Description

Technical Field

[0001] This invention claims priority to French application 2102479, filed on March 12, 2021, the contents of which (text, drawings and claims) are incorporated herein by reference.

[0002] This invention relates to the installation of battery chargers on the body of motor vehicles.

[0003] More specifically, the present invention relates to an improved device for ensuring a connection between a battery charger, a support for supporting the battery charger, and the vehicle body, respectively. Background Technology

[0004] A battery charger mounted on a motor vehicle is a relatively heavy (around ten kilograms) and space-consuming component housed in a support structure (which is fixed under the vehicle body). This support structure is typically formed of a frame in which the charger is housed, and the frame is equipped with vertical tabs that ensure connection to the vehicle body.

[0005] The support member is subjected to oscillating motion due to the vibration of the vehicle body and the inertia of the charger. However, these stresses eventually cause deformation, which may lead to the breakage of the support member and the fall of the charger. Therefore, currently available support joints do not have good durability.

[0006] Patent EP1479567B1 describes a support for receiving high-voltage electrical equipment and for suspending the high-voltage electrical equipment onto a structural component of a motor vehicle. The support is perforated to allow ventilation of the high-voltage equipment.

[0007] Patent EP2767428B1 describes a suspended charger support equipped with reinforcing and guiding elements, and capable of rigidifying (in its mounting position on the vehicle body) the assembly consisting of the support and the charger.

[0008] However, none of the preceding documents disclose a technical solution that can simultaneously ensure the rigidity and stability of the charger support (without increasing the footprint and without resorting to additional components) and the assembly of the charger in a location closer to the vehicle body or at least in close proximity to the "machine tool board" (referred to as POM, which is used for the assembly of different components on the chassis of the vehicle). Summary of the Invention

[0009] In this context, the present invention aims to overcome the technical problems posed by the preceding solutions by providing an improved support device for supporting a charger, wherein an assembly joint for assembly with the charger is added, wherein thereafter the assembly joint is horizontal and separate from the stand.

[0010] This new configuration allows the support to be positioned and assembled closer to the vehicle body before the charger is placed on the stand, while also making it easy to access the assembly components used for assembling between the support and the charger.

[0011] According to the invention, this objective is achieved by means of a support device for supporting a battery charger for mounting the battery charger under the body of a motor vehicle. The device includes a frame and at least two vertical arms integrally connected to the frame. A housing for housing the charger rests on the frame, and the at least two vertical arms ensure the suspension of the frame under the vehicle body. The housing is characterized by having at least one protruding tab that ensures assembly with an angled partition, which, on one hand, abuts against a side wall of the housing, and on the other hand, has its upper surface fixed under the vehicle body in parallel with the vertical connecting arms.

[0012] According to an advantageous feature, the tab is configured to face a corresponding opening provided on the separator to accommodate a component for assembling the tab and the separator together.

[0013] When needed, the tab is provided with at least one orifice, which is used to face a corresponding orifice provided on the separator to accommodate an assembly screw.

[0014] According to another advantageous feature, the end of the partition is provided with a side opening for mounting a fixing element under the vehicle body.

[0015] Preferably, the side openings of the separator are located on both sides of the opening for assembly with the tabs of the housing.

[0016] In a variation of the device according to the invention, the side opening is configured to pass through a boss that extends along a plane located above the upper surface of the housing.

[0017] According to another variation, the separator is provided with a base that ensures connection with the frame.

[0018] According to a preferred embodiment of the device of the present invention, the housing has two horizontal and parallel tabs.

[0019] Preferably, the housing and the bracket are fixed on the lower edge of the side wall of the housing located on the side opposite to the partition.

[0020] The invention is also designed such that the separator includes at least one recess for receiving and securing the assembly tabs of the housing.

[0021] Another object of the present invention is to provide a motor vehicle equipped with a support device having the above-described features for supporting a battery charger.

[0022] Therefore, the device of the present invention is to modify the position of the joint between the seat and the charger, which can rigidify the connection between the seat and the charger, strengthen the assembly, and ensure reliable and stable assembly of the charger under the vehicle body over time, even in the presence of large vibrations or stresses (such as collisions).

[0023] Thus, the device of the present invention can solve the problem of low mechanical durability of the preceding technical solutions, while allowing the charger to be arranged closer to the vehicle body (especially closer to the machine tool board) without adding material and therefore without increasing the weight of the vehicle.

[0024] Therefore, the present invention can produce a more rigid charger / charger support assembly with the same material input, or even with a smaller metal plate thickness. Attached Figure Description

[0030] For clarity, identical or similar elements are represented by the same reference numerals in the specification and its accompanying drawings.

[0031] Naturally, the embodiments of the invention's apparatus shown in the accompanying drawings, illustrated above and described below, are given only as non-limiting examples. It is expressly stated that different embodiments may be provided and other embodiments may be proposed by combining said different embodiments with each other.

[0032] The present invention relates to the integration of a battery charger into a structural component of a motor vehicle, and more specifically to the assembly of a support for supporting the charger under the vehicle body.

[0033] The battery charger mounted on a motor vehicle is a relatively heavy component (weighing around ten kilograms), housed in a support structure fixed to the underside of the vehicle body. This support typically includes a frame and at least two vertical arms integrally formed with the frame. The housing containing the charger rests on the frame, and the at least two vertical arms ensure a suspended connection under the vehicle body.

[0034] The present invention aims to rigidify the support / charger assembly to prevent harmful swaying of the mounting bracket. To this end, as... Figure 1A , Figure 1B and Figure 1C As shown, a preferred embodiment is presented, wherein the charger housing 1 is designed such that at least one (two in this case) parallel and protruding tabs 11a, 11b extend along a substantially horizontal plane in its upper portion. These tabs ensure assembly with the angled partition 2, which, on the one hand, abuts against the side wall 1a of the housing 1, and on the other hand, is secured to the underside of the vehicle body C by its upper surface and two vertical connecting arms 31 (for connecting the seat 3 to the vehicle body C), particularly as... Figure 1B As shown.

[0035] Each of the tabs 11a and 11b of the housing 1 is provided with at least one opening 10, said at least one opening being for facing a corresponding opening 20 provided on the partition 2, for accommodating screws 4 for vertically assembling the housing 1 and the partition 2. Figure 1B The orifice 20 of the separator 2 is provided in the bottom of one or more recesses 22, which are used to receive and secure the tabs 11a, 11b.

[0036] The end of the separator 2 is equipped with a side opening 21 for mounting a fixing element (not shown) under the vehicle body C.

[0037] Preferably, these side openings 21 are configured to pass through bosses 24, which extend along a plane located above the upper surface 1b of the housing 1 and are located on both sides of the openings 20 for assembly with the tabs 11a, 11b.

[0038] exist Figure 2 In this embodiment, the partition 2 is fixed horizontally instead of vertically. For this purpose, the orifice 20 of the partition is configured to pass through the sidewall of the partition and receive facing tabs 11a, 11b present here by the sidewall 1a of the housing 1. These tabs are secured, for example, by bolts through the orifice 20. A stop 12 on the upper edge of the housing 1 ensures the stability of the partition 2 towards the top. The partition 2 can thus be positioned and assembled onto the housing 1 by means of the lug 13, and simultaneously secured.

[0039] The housing 1 and the base 3 are fixed to the lower edge of the side wall 1c of the housing, which is located on the side opposite to the surface 1a on which the partition 2 abuts. The partition 2 is provided with a base 23, which ensures the connection with the base 3. Figure 1B ).

[0040] The fixing mode advocated by the present invention enables the assembly consisting of the seat frame 3 and the charger housing 1 to be closer to the vehicle body C and ensures satisfactory stability, even when there is vibration or collision on the vehicle.

[0041] Furthermore, the support device of the present invention enables easy assembly of the charger under the vehicle body C. This assembly is first performed by arranging the housing 1 containing the charger on the mount 3 via side access near the tool plate (POM). The next step involves positioning and assembling the separator 2 onto the tabs 11a, 11b of the housing 1, thereby closing the side access to the mount 3. The final assembly is completed by vertically inserting screws through the orifice 20 of the separator 2 until they are inserted into threaded holes (not shown) designed for this purpose under the vehicle body C.
