Specification

Description:[001] PREAMBLE TO THE DESCRIPTION

[002] The following specification particularly describes the invention and the manner in which it is to be performed.

[003] TECHNICAL FIELD

[004] The present disclosure generally relates to the field of automobiles. Particularly, but not exclusively, the present disclosure relates to a frontbox of the vehicle, preferably electrical heavy duty vehicles. Further, embodiments of the present disclosure disclose a mounting assembly for the frontbox of the vehicle.

[005] BACKGROUND

[006] Increase in transportation of goods and movement of passengers, has led to a high demand for vehicles, especially commercial vehicles, and passenger vehicles. As road travel is the cheapest mode of travel, majority of the people prefer to travel through public vehicles, preferably buses. The vehicles, preferably heavy duty vehicles require more power to run driving wheels of the vehicle due to high amount of load. The power generation can be increased by increasing rate of combustion of fuels, for example - petrol, diesel, gasoline and likewise in a power stroke of Internal combustion engines. The combustion of more fuel results in generation of more exhaust gases that tend to pollute the environment. In order to curb the pollution caused by burning of fuels, the vehicle industries are moving towards implementation of electric vehicles, that require current to drive a traction motor associated with the vehicle and the traction motor is connected to the driving wheels through a power transmission unit.

[007] The implementation of traction motor to drive the vehicle may have resulted in lesser pollution. However, the operation of traction motor requires a precise control mechanism that governs proper and required actuation of the traction motor by regulating amount of current passed to the traction motor from a battery module. Most of the electric vehicles, preferably heavy duty electric vehicles, for example - electric buses, trucks and likewise, comprise a frontbox area or compartment disposed at a front portion of the vehicle. The frontbox compartment generally comprises a plurality of mounting means to facilitate mounting of different controllers, power boxes, circuits, busbars and likewise. However, the mounting of such components is often challenging to the vehicle manufactures, because of the packaging constraint present inside the frontbox, accessibility of such components disposed inside the frontbox and thereby difficulty in serviceability of such components mounting inside the frontbox.

[008] Conventionally, vehicle manufacturers have sought, proposed, and implemented different solutions to address the above problem. One of the existing solutions include mounting of such electronic components on a vertical frame which in turn is fixed to a frontal chassis of the vehicle. The vertical mounting or orientation of the components may have facilitated packaging of components in a limited space, but such a vertical orientation of the components causes misalignment during service, damaging tapped holes, and thereby increasing vehicle downtime. The heavy cover plate during removal and assembly, and the cradle structure blocking access, further exacerbate these issues. The frontbox generally has two Variable Frequency Drive [VFD] units, but their access is blocked by surrounding components, especially of the bottom VFD. This results in additional downtime as a top VFD and other peripheral components must be removed to access the bottom VFD. The vertical mounting of the components may also exhibit uneven weight distribution, with more load concentrated on the RH side due to vertical placement of junction box and VFDs.

[009] Some of the existing assemblies for frontbox of a vehicle are disclosed in CN utility patent no. CN206306808U [referred as '808 publication hereafter], CN utility patent no. CN215042597U [referred as '597 publication hereafter]and CN utility patent no. CN201530302U [referred as '302 publication hereafter].

[010] The '808 publication discloses an electric vehicle that comprises a fixed suspension structure assembly. The assembly comprises vertical supports, for instance - upper mounting plates are bolted onto the vertical supports. The upper mounting plates serve as mounting base to facilitate mounting of the components associated with the vehicle, for example - mounting of the junction box. The '808 publication discloses the assembly that facilitates a mounting of the components in a vertical orientation and thereby may cause of the above mentioned problems, for example - increase in downtime of the vehicle, due to increase time in servicing of the vehicle, difficult in accessing the components that are positioned behind the other components, uneven weight distribution and likewise.

[011] The '597 publication relates to a heavy-duty truck comprising a universal electric control integrated bracket, the high voltage box mounted on top, and a motor controller mounted on bracket. A mounting of a MCU bracket the design has vertical structural supports. The vertical structural supports have vertical mounting scheme on one side. The universal electric control structural is bolted to a longitudinal bar of vehicle. Similar to '808 publication, the '597 publication also discloses mounting of the components associated with the heavy duty truck in a vertical orientation and thereby may cause similar problems.

[012] The '302 publication discloses an electric vehicle comprising a battery box structural assembly. The assembly comprises batteries which are mounted on top and bottom of a bracket. The assembly discloses vertical structural supports have vertical mounting schemes. The '302 publication does not disclose the specific mounting of the electronic components of the electric vehicle that aids in improving the serviceability of the vehicle and at the same time are easily accessible.

[013] The prior arts described above, and other such known arts disclose different assemblies for mounting the components associated with the vehicle, preferably with the frontbox of the vehicle. However, such constructions do not provide a simplified assembly to facilitate easy accessibility of all the components improving the serviceability of the vehicle and simultaneously decreasing the downtime of the vehicle.

However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles "a" or "an" limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases "one or more" or "at least one" and indefinite articles such as "a" or "an" (e.g., "a" and/or "an" should typically be interpreted to mean "at least one" or "one or more"); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of "two recitations," without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to "at least one of A, B, and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, and C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances, where a convention analogous to "at least one of A, B, or C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B, or C" would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase "A or B" will be understood to include the possibilities of "A" or "B" or "A and B." While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope being indicated by the following claims.
