[0001] This utility model relates to the field of vehicle integrated on-board power management module installation technology, specifically to a bracket assembly and a vehicle. Background Technology

[0002] With technological advancements, new energy vehicles are becoming increasingly popular and accepted by consumers. As new models introduce more and more electrical functions, the number of electrical components also increases, placing higher demands on space allocation and making traditional electrical component layout methods difficult.

[0003] An integrated on-board power management module (ODP) refers to a module that integrates functions such as an OBC (On-Board Charger), DC / DC converter, and PDU (Power Distribution Unit). Existing integrated ODPs are typically located in the center floor unit and have four mounting points, secured to the suspension with four mounting bolts. This placement necessitates a maintenance access cover on the center floor, and the large size of this cover makes sealing the center floor difficult, potentially leading to leaks. Therefore, a new installation method for integrated ODPs is needed to meet the installation requirements of integrated ODPs in new energy vehicles. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a bracket assembly and vehicle to improve the problem that the existing integrated vehicle power management module installation structure requires a maintenance access cover to be opened on the floor of the vehicle, which leads to poor sealing of the floor and easy leakage.

[0005] To achieve the above and other related objectives, the first aspect of this utility model provides a bracket assembly, including a mounting component and a protective component; the mounting component is configured to be fixed to the rear engine compartment of a vehicle; the protective component is detachably fixed to the mounting component, and the protective component and the mounting component form a mounting cavity, the mounting cavity being configured to mount an integrated vehicle power management module.

[0006] In an exemplary embodiment of the present invention, the mounting component is provided with reinforcing ribs, which are arranged along the length direction of the vehicle.

[0007] In an exemplary embodiment of this utility model, the reinforcing rib protrudes toward the protective member.

[0008] In an exemplary embodiment of the present invention, the reinforcing rib has a groove formed on the side away from the protective member, and a first connecting portion protruding relative to the groove is formed between the grooves, and the first connecting portion is fixed to the vehicle floor.

[0009] In an exemplary embodiment of this utility model, the mounting component has a first protrusion near the protective component, and a first connector is provided on the first protrusion. The first connector is used to connect the integrated vehicle power management module.

[0010] In an exemplary embodiment of the present invention, the mounting member is provided with a second protrusion on the side near the protective member, and a second connecting member is provided on the second protrusion, and the protective member is connected to the second connecting member.

[0011] In an exemplary embodiment of the present invention, the protective member includes a first protective plate, a second protective plate, and a third protective plate. The second protective plate and the third protective plate are respectively disposed on opposite sides of the first protective plate, and the second protective plate and the third protective plate extend toward the mounting member.

[0012] In an exemplary embodiment of this utility model, a second connecting plate is provided at the end of the second guard plate away from the first guard plate, and the second connecting plate abuts against the mounting member; a third connecting plate is provided at the end of the third guard plate away from the first guard plate, and the third connecting plate abuts against the mounting member; the second connecting plate and the third connecting plate extend in opposite directions.

[0013] A second aspect of this utility model provides a vehicle, the vehicle including the bracket assembly and the rear engine compartment as described above, the bracket assembly being disposed on the lower side of the rear engine compartment of the vehicle.

[0014] In an exemplary embodiment of the present invention, the vehicle includes a floor beam, and one end of the mounting member is fixed to the floor beam of the vehicle.

[0015] In combination with existing technologies, the beneficial effects of this utility model are as follows:

[0016] Existing integrated vehicle power management modules are installed in the lower part of the vehicle floor and mounted on the suspension with bolts.

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. It should also be understood that the terminology used in the embodiments of this utility model is for describing specific implementation schemes and not for limiting the scope of protection of this utility model. Test methods in the following embodiments that do not specify specific conditions are generally performed under conventional conditions or according to the conditions recommended by the respective manufacturers.

Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, equipment, and materials similar to or equivalent to those in the embodiments of this invention.

[0028] It should be noted that the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0029] With the increasing popularity of new energy vehicles, the requirements for the layout of electrical components in these vehicles are becoming more and more stringent. Existing integrated vehicle power management modules are generally located in the lower part of the floor panel and are mounted on the suspension with four mounting bolts. To facilitate maintenance, a maintenance access cover needs to be installed in the floor panel. Because the integrated vehicle power management module itself is relatively large, the required size of the maintenance access cover is also relatively large. This makes it difficult to control the seal at the maintenance access cover, which can easily lead to water leakage and affect the overall quality of the vehicle.

[0030] In view of this, the present invention provides a bracket assembly and a vehicle to facilitate the installation of an integrated vehicle power management module. By fixing the mounting component to the rear engine compartment of the vehicle, which has a large space, the integrated vehicle power management module can be installed under the rear engine compartment without the need for a maintenance access panel, thus ensuring the integrity of the rear engine compartment and avoiding water leakage problems caused by a maintenance access panel cover. The protective component and the mounting component form an installation cavity to protect the integrated vehicle power management module from damage due to impacts, improving driving safety.

[0031] Please see Figures 1 to 5 The first aspect of this utility model provides a bracket assembly, which includes a mounting member 100 and a protective member 200. The mounting member 100 is configured to be fixed to the rear engine compartment 300 of a vehicle. By fixing the mounting member 100 to the rear engine compartment 300, the lower space of the rear engine compartment 300 can be effectively utilized, avoiding locations such as the floor suspension, and facilitating the disassembly, assembly, and maintenance of the integrated vehicle power management module 500 from the lower side of the rear engine compartment 300. The protective member 200 is detachably fixed to the mounting member 100. The protective member 200 and the mounting member 100 form a mounting cavity 240, which is configured to mount the integrated vehicle power management module 500. The mounting cavity 240 protects the integrated vehicle power management module 500, reducing the risk of impact damage and improving driving safety. The protective component 200 and the mounting component 100 are detachable and fixed. The protective component 200 can be removed and installed through the space under the rear engine compartment 300, thereby allowing the integrated vehicle power management module 500 to be disassembled, installed, and maintained. This avoids opening a maintenance port on the vehicle floor, solving the problem of water leakage caused by opening a maintenance port, improving the sealing of the vehicle floor, and improving the convenience of maintenance of the integrated vehicle power management module 500.

[0032] In one embodiment, the mounting component 100 is fixed to the rear floor of the rear engine compartment 300 to facilitate the installation of the mounting component 100, the protective component 200, and the integrated vehicle power management module 500 using the bottom space of the rear engine compartment 300.

[0033] Of course, as some alternatives, the mounting component 100 can also be fixed to other components of the rear engine compartment 300 to achieve the installation and fixation of the mounting component 100 and the installation of the integrated vehicle power management module 500.

[0034] In one embodiment, the mounting component 100 may be a horizontally arranged thin plate structure, which is fixed to the rear engine compartment 300 of the vehicle by means of welding, adhesive bonding, snap-fit ​​connection, or bolt connection. Preferably, the mounting component 100 is connected to the rear engine compartment 300 of the vehicle by welding. Welding two thin plate structures is a mature and simple process with good stability, and will not damage the rear engine compartment 300 or the mounting component 100, thus avoiding problems such as leakage.

[0035] Please see Figure 4 and Figure 5 In one embodiment, the mounting component 100 is provided with reinforcing ribs 110. The reinforcing ribs 110 increase the strength of the mounting component 100, thereby improving the installation stability of the protective component 200 and the integrated vehicle power management module 500. The reinforcing ribs 110 are arranged along the length of the vehicle. When the vehicle moves forward or backward, it is prone to collisions with uneven ground or foreign objects. During a collision, the force is applied in the longitudinal direction, i.e., along the length of the vehicle. By providing reinforcing ribs 110 along the length of the vehicle, the strength of the mounting component 100 in the vehicle's length direction is effectively increased, enhancing the protection of the integrated vehicle power management module 500 and reducing the risk of collision damage to the integrated vehicle power management module 500.

[0036] Please see Figure 4 Multiple reinforcing ribs 110 are spaced apart to improve the strength of each area of ​​the mounting component 100. Adjacent reinforcing ribs 110 can be spaced equally to make the strength of each area of ​​the mounting component 100 more consistent. Of course, adjacent reinforcing ribs 110 can also be spaced unequally, adapted to the strength requirements of each area of ​​the mounting component 100 and the shape of the rear engine compartment 300 of the vehicle.

[0037] There are multiple reinforcing ribs 110, and the number of reinforcing ribs 110 can be selected according to actual needs, such as 2, 4, 5, 6, etc.

[0038] Please see Figure 4 In one embodiment, the reinforcing rib 110 protrudes toward the protective member 200. The side of the mounting member 100 away from the protective member 200 is used to fix it to the vehicle's lower floor. The reinforcing rib 110 protruding toward the protective member 200 can avoid interference between the mounting member 100 and the vehicle's lower floor, and facilitate the installation of the mounting member 100 while improving its strength.

[0039] Please see Figure 4 In one embodiment, the reinforcing rib 110 is integrally formed with the main body of the mounting component 100. For example, the reinforcing rib 110 is directly generated when the mounting component 100 is stamped or hydraulically pressed, which is convenient and simple to process and ensures the connection strength between the reinforcing rib 110 and the main body of the mounting component 100. The reinforcing rib 110 effectively improves the strength of the mounting component 100.

[0040] Please see Figure 4 In one embodiment, the reinforcing rib 110 has a groove 120 formed on the side opposite to the protective member 200, which facilitates the integral formation of the reinforcing rib 110 and the main body of the mounting member 100 by stamping or hydraulic means, thereby reducing the weight of the mounting member 100. A first connecting portion 130 protrudes from the groove 120 between the grooves 120. The first connecting portion 130 is fixed to the vehicle floor. The grooves 120 are connected through the first connecting portion 130. Compared to fixing the entire surface of the mounting member 100 to the vehicle floor, the area of ​​the mounting member 100 at the fixing point to the vehicle floor can be reduced by using a small-area connection and fixing instead of a large-area connection and fixing. This makes it easier to fix the mounting member 100 to the vehicle floor, reduces the fitting precision between the mounting member 100 and the vehicle floor, reduces the production precision of the mounting member 100, thereby reducing the production cost of the mounting member 100 and improving product competitiveness.

[0041] Please see Figure 2 and Figure 5 In one embodiment, the mounting member 100 has a first protrusion 150 near the protective member 200. The first protrusion 150 protrudes from the surface of the main body of the mounting member 100, which can effectively improve the strength of the first protrusion 150. A first connector 151 is provided on the first protrusion 150. The first connector 151 is used to connect the integrated vehicle power management module 500, which effectively improves the stability of the connection of the integrated vehicle power management module 500 and reduces the risk of the first connector 151 detaching from the mounting member 100.

[0042] Please see Figure 2 and Figure 5 The first boss 150 and the main body of the mounting part 100 are integrally formed by stamping or hydraulic methods to facilitate the production and processing of the mounting part 100. The cross-section of the first boss 150 can be square, circular, etc., selected according to actual needs. It should be noted that when the cross-section of the first boss 150 is square or other angular shapes, the transitions between the edges are all arc-shaped, that is, the edge transitions of the cross-section of the first boss 150 are all arc-shaped, to avoid stress concentration and ensure the strength of the first boss 150.

[0043] The first connector 151 includes, but is not limited to, bolts, to facilitate the connection between the first connector 151 and the integrated vehicle power management module 500. The connection method between the first connector 151 and the first boss 150 includes, but is not limited to, welding, preferably welding, such as projection welding, to ensure the connection strength between the first connector 151 and the first boss 150.

[0044] Multiple first protrusions 150 and first connectors 151 are provided, such as 3, 4, 6, 7, 8, etc., to meet the connection strength requirements of the integrated vehicle power management module 500. Multiple first protrusions 150 are distributed in the areas where the mounting member 100 abuts against the edge region of the integrated vehicle power management module 500, to facilitate the fixing of the integrated vehicle power management module 500.

[0045] Please see Figure 2 and Figure 5 In one embodiment, the mounting member 100 has a second protrusion 160 on the side near the protective member 200. The second protrusion 160 protrudes from the surface of the main body of the mounting member 100, which can effectively improve the strength at the first protrusion 150. A second connector 161 is provided on the second protrusion 160, and the protective member 200 is connected to the second connector 161, which effectively improves the connection strength between the protective member 200 and the mounting member 100, ensuring the protection of the integrated vehicle power management module 500 by the protective member 200.

[0046] Please see Figure 2 and Figure 5 In one embodiment, the second boss 160 and the main body of the mounting component 100 are integrally formed by stamping or hydraulic pressing to facilitate the production and processing of the mounting component 100. The cross-section of the second boss 160 can be square, circular, etc., selected according to actual needs. It should be noted that when the cross-section of the second boss 160 is square or other angular shapes, the transitions between the edges are all arc-shaped, that is, the transitions at the edges of the cross-section of the second boss 160 are all arc-shaped, to avoid stress concentration and ensure the strength of the second boss 160.

[0047] The second connector 161 can be a bolt or other connector to facilitate the assembly and disassembly of the protective component 200 and the mounting component 100. The connection method between the second connector 161 and the second boss 160 includes, but is not limited to, welding connection, preferably welding connection, such as projection welding, to ensure the connection strength between the second connector 161 and the second boss 160.

[0048] Multiple second bosses 160 and second connectors 161 are provided, such as 3, 4, 6, 7, 8, etc., to ensure the installation strength of the protective component 200. Multiple second bosses 160 are distributed in the area where the mounting component 100 abuts against the edge area of ​​the protective component 200, so as to facilitate the fixing of the protective component 200.

[0049] In one embodiment, the second protrusion 160 is disposed on the outside of the first protrusion 150, so that the integrated vehicle power management module 500 is completely installed on the inside of the protective member 200, thereby ensuring the protection of the integrated vehicle power management module 500 by the protective member 200.

[0050] Please see Figure 2 and Figure 3 In one embodiment, the protective component 200 includes a first protective plate 210, a second protective plate 220, and a third protective plate 230. The second protective plate 220 and the third protective plate 230 are respectively disposed on opposite sides of the first protective plate 210. The first protective plate 210 is located at the bottom of the integrated vehicle power management module 500 to protect the bottom of the integrated vehicle power management module 500. The second protective plate 220 and the third protective plate 230 are respectively disposed on the front and rear sides of the integrated vehicle power management module 500, with the front direction referring to the vehicle's forward direction and the rear direction referring to the vehicle's reverse direction. The second protective plate 220 and the third protective plate 230 respectively protect the front and rear sides of the integrated vehicle power management module 500. Since vehicles usually move forward and backward, the front and rear sides of the integrated vehicle power management module 500 are more susceptible to impacts when bumped. The second protective plate 220 and the third protective plate 230 can effectively reduce the risk of damage to the integrated vehicle power management module 500 from bumps. The integrated vehicle power management module 500 does not have protective parts 200 on its left and right sides, which can reduce the weight of the protective parts 200 and thus facilitate vehicle weight reduction.

[0051] Of course, as optional features, the protective component 200 may also include a third protective plate 230 and a fourth protective plate, which protect the left and right sides of the integrated vehicle power management module 500 to provide better protection. For example, some new energy vehicles can move laterally; the third and fourth protective plates can protect the left and right sides of the integrated vehicle power management module 500 during this movement.

[0052] The second protective plate 220 and the third protective plate 230 extend toward the mounting member 100 to effectively protect the integrated vehicle power management module 500.

[0053] In one embodiment, the second protective plate 220 and the third protective plate 230 may extend perpendicularly to the first protective plate 210 toward the protective member 200. The connection points between the second protective plate 220 and the third protective plate 230 and the first protective plate 210 are respectively arc-shaped to avoid stress concentration at the connection points between the second protective plate 220 and the first protective plate 210 and the third protective plate 230 and the first protective plate 210, thereby improving the connection strength.

[0054] In another embodiment, the second protective plate 220 is not perpendicular to the first protective plate 210, and the third protective plate 230 is not perpendicular to the first protective plate 210. Along the direction of the first protective plate 210 toward the mounting plate, the second protective plate 220 and the third protective plate 230 are inclined in opposite directions, thereby forming an obtuse angle between the second protective plate 220 and the first protective plate 210, and between the third protective plate 230 and the first protective plate 210. This effectively improves the strength of the connection between the second protective plate 220 and the first protective plate 210, and the strength of the connection between the third protective plate 230 and the first protective plate 210, thereby effectively protecting the integrated vehicle power management module 500 and reducing the risk of damage to the integrated vehicle power management module 500.

[0055] Please see Figure 2 In one embodiment, a second connecting plate 221 is provided at the end of the second protective plate 220 away from the first protective plate 210. The second connecting plate 221 abuts against the mounting member 100. Preferably, the second connecting plate 221 abuts against the second boss 160, so as to fix the mounting member 100 and the protective member 200 through the cooperation of the second connecting plate 221 and the second connecting member 161. A third connecting plate 231 is provided at the end of the third protective plate 230 away from the first protective plate 210. The third connecting plate 231 abuts against the mounting member 100. Preferably, the third connecting plate 231 abuts against the second boss 160, so as to fix the mounting member 100 and the protective member 200 through the cooperation of the third connecting plate 231 and the second connecting member 161. The second connecting plate 221 and the third connecting plate 231 extend in opposite directions to improve the connection stability between the protective member 200 and the mounting member 100.

[0056] In one embodiment, the second connector 161 is a bolt. The second connecting plate 221 and the third connecting plate 231 are respectively provided with through holes to accommodate the bolt. After the bolt passes through the through hole, the nut and the bolt are threaded together, so as to realize the detachable fixing of the protective part 200 and the mounting part 100, which facilitates the disassembly, assembly and maintenance of the integrated vehicle power management module 500.

[0057] A second aspect of this utility model provides a vehicle comprising the bracket assembly described above and a rear engine compartment 300. The bracket assembly is disposed under the rear engine compartment 300 of the vehicle, thereby avoiding obstruction of the suspension and facilitating the disassembly, installation, and maintenance of the integrated vehicle power management module 500 from below. Installing the integrated vehicle power management module 500 using the bracket assembly also avoids the need for a maintenance access port or cover on the vehicle floor, improving the waterproofing of the vehicle floor.

[0058] Please see Figure 2In one embodiment, the vehicle includes a floor beam 400, and one end of the mounting member 100 is fixed to the floor beam 400 of the vehicle. Preferably, the front end of the mounting member 100 is fixed to the floor beam 400. The mounting member 100 is fixed by the floor beam 400 to ensure the installation strength of the mounting member 100 and reduce the risk of floor deformation caused by the installation of the integrated vehicle power management module 500 and bracket assembly.

[0059] In one embodiment, the rear engine compartment 300 of the vehicle has a recessed portion that curves inwards into the vehicle. The bracket assembly is mounted in the recessed portion, thereby increasing the height of the bracket assembly and reducing the risk of impact damage to the bracket assembly and the integrated vehicle power management module 500. The recessed portion also increases the overall strength of the rear engine compartment 300, thereby improving the torsional strength and safety of the vehicle body.

[0060] Please see Figure 2 and Figure 5 The mounting component 100 is provided with a first bending portion and a second connecting portion 170. The first bending portion overlaps with the edge of the recess, thereby allowing the second connecting portion 170 to extend out of the recess and be fixed to the floor beam 400. The second connecting portion 170 is preferably fixed to the floor beam 400 by welding, which is a mature and stable process and is convenient to manufacture.

[0061] The bracket assembly and vehicle of this utility model allow for the detachable fixing of the protective component 200 and the mounting component 100. The protective component 200 can be installed and removed through the space under the rear engine compartment 300, enabling the disassembly, installation, and maintenance of the integrated vehicle power management module 500. This avoids the need for maintenance access points on the vehicle floor, solving the problem of water leakage caused by such access points, improving the sealing of the vehicle floor, and enhancing the convenience of maintenance for the integrated vehicle power management module 500. The protective component 200 protects the front, lower, and rear of the integrated vehicle power management module 500, effectively resisting collisions and improving safety performance. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus possessing high utilization value and practical significance.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
