Description

Technical Field

[0001] This invention belongs to the field of electric vehicle battery installation technology, specifically relating to a shared bracket for a battery and a controller. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Electric vehicles (EVs) are vehicles powered by onboard electricity, driven by electric motors, and that comply with all road traffic and safety regulations. Due to their relatively smaller environmental impact compared to traditional vehicles, their prospects are widely considered promising. However, EVs have diverse power structures, numerous configurations and functions, and a large number of electrical components. This complexity leads to insufficient usable space in the engine compartment, especially for the battery and mounting brackets. Other electrical components, such as chargers, DC-DC converters, and motor controllers, occupy a significant amount of space, leaving insufficient room for the battery and brackets. Furthermore, the rear area controller is another crucial component of EVs. Developing mounting brackets for the rear area controller to meet its installation requirements is complex, time-consuming, and involves a sophisticated installation process.

[0004] In the prior art, the rear area controller and low-voltage battery are usually installed separately using rear area controller brackets and low-voltage battery brackets, which results in a large space occupation, a relatively complex installation structure, and fails to meet the requirements of lightweight design. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a shared bracket and installation method for a battery and controller, which enables integrated installation of the battery and controller, reduces space occupation, and simplifies the installation structure.

[0006] The technical solution of the present invention is as follows:

[0007] In a first aspect of the invention, a shared bracket for a battery and a controller is provided, comprising a bracket body, wherein the bracket body is provided with a controller mounting surface and a battery mounting groove, the controller mounting surface and the surface where the battery mounting groove is located form an obtuse angle, the controller mounting surface is fixedly mounted with a controller, the battery mounting groove is fixedly mounted with a battery, and the bracket body is fixed to the vehicle body floor and wheel arches.

[0008] In some embodiments of the present invention, a bracket support plate is provided on the back of the controller mounting surface. The bracket support plate has a Z-shaped structure and is mounted on the wheel cover.

[0009] In some embodiments of the present invention, a mounting hole is provided on the surface where the battery mounting slot is located, the battery mounting slot is engaged with one side of the battery, and the surface where the battery mounting slot is located and one side of the battery bracket are fixed to the vehicle floor.

[0010] In some embodiments of the present invention, two mounting holes are provided, one being a round hole and the other an oblong hole.

[0011] In some embodiments of the present invention, the controller mounting surface and the battery mounting groove are connected by a first connecting beam, a second connecting beam and a third connecting beam, wherein one side of the first connecting beam is connected to the controller mounting surface and the other side is connected to one end of the second connecting beam and the third connecting beam, and the other end of the second connecting beam and the third connecting beam is connected to the battery mounting groove.

[0012] In some embodiments of the present invention, a quadrilateral through hole is formed between the first connecting beam, the second connecting beam, the third connecting beam, and the surface where the battery mounting groove is located.

[0013] In some embodiments of the present invention, the first connecting beam, the second connecting beam and the third connecting beam are all provided with weight-reducing holes, and the length of the second connecting beam is less than the length of the third connecting beam.

[0014] In some embodiments of the present invention, the support body is an integral structure.

[0015] In some embodiments of the present invention, four mounting holes are provided on the mounting surface of the controller, the mounting holes are located on a step, and the controller is mounted on the mounting surface of the controller by bolts.

[0016] In a second aspect of the invention, a method for installing a battery and a controller sharing a common bracket is provided, comprising the following steps:

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] In a typical embodiment of the present invention, a shared bracket for the battery and controller is proposed, such as... Figure 1-4 As shown, the device includes a bracket body 1, on which a controller mounting surface 3 and a battery mounting groove 7 are provided. The controller mounting surface 3 and the surface where the battery mounting groove 7 is located form an obtuse angle. The controller mounting surface 3 is used to fix the controller, and the battery mounting groove 7 is used to fix the battery. The bracket body 1 is fixed to the vehicle floor and wheel arches to support the installation of the controller and the battery.

[0036] like Figure 5 As shown, a flange 10 is provided on one side of the surface 7 where the battery mounting slot is located. Multiple battery mounting slots 7 are provided on the flange 10. The battery mounting slots 7 are adapted to the engaging slots on the battery. The battery mounting slots 7 engage with one side of the battery, and the battery is mounted on the battery bracket to realize the installation of the battery on a common bracket. The surface 7 where the battery mounting slot is located is provided with mounting holes. There are two mounting holes, one is a round hole 8 and the other is an oblong hole 9. The mounting holes are used to fix the surface 7 where the battery mounting slot is located and one side of the battery bracket to the vehicle floor. By making one mounting hole an oblong hole, it is easier to adapt to different manufacturing and assembly requirements.

[0037] like Figure 6As shown, the controller mounting surface 3 is provided with controller mounting holes 4. Specifically, there are four controller mounting holes 4, located at the four corners of the controller mounting surface 3. To ensure a better fit between the controller and the controller mounting surface 3 during installation, the four controller mounting holes 4 are positioned on a step, meaning the surface of the controller mounting surface that contacts the controller is slightly lower than the surface where the controller mounting holes are located. The controller mounting surface 3 also has a first weight-reducing hole 11. One side of the first weight-reducing hole 11 is connected to a bracket support plate 2. The bracket support plate 2 is located on the side of the controller mounting surface 3 and has a Z-shaped structure. It is mounted on the wheel arch. By setting the bracket support plate in a Z-shaped structure, it can provide a certain degree of shock absorption, reducing the impact of vehicle vibration on the controller. The first weight-reducing hole 11 not only serves a shock-reducing function but also provides return space for the bracket support plate 2. When the controller mounting surface 3 is large, other weight-reducing holes can be provided on the controller mounting surface to further reduce the weight of the bracket. For example, L-shaped weight-reducing holes can be provided around the first weight-reducing hole. The size of these holes can be adjusted according to the actual situation, as long as it does not affect the strength of the bracket.

[0038] Furthermore, the controller mounting surface 3 and the battery mounting groove surface 5 are connected by a first connecting beam 12, a second connecting beam 14, and a third connecting beam 16. One side of the first connecting beam 12 is connected to the controller mounting surface 3, and the other side is connected to one end of the second connecting beam 14 and the third connecting beam 16. The other end of the second connecting beam 14 and the third connecting beam 16 is connected to the battery mounting groove surface 5. A quadrilateral through hole is formed between the first connecting beam 12, the second connecting beam 14, the third connecting beam 16, and the battery mounting groove surface 5. The quadrilateral through hole can play a role in shock absorption and can also allow the wiring harness connected to the controller to be connected to other components through the wire speed groove 19.

[0039] Furthermore, weight-reduction holes are provided on the first connecting beam 12, the second connecting beam 14, and the third connecting beam 16. Specifically, the first connecting beam 12 has a second weight-reduction hole 13, the second connecting beam 14 has a third weight-reduction hole 15, and the third connecting beam 16 has a fourth weight-reduction hole 17. These weight-reduction holes reduce the weight of the shared bracket. The length of the second connecting beam 14 is shorter than the length of the third connecting beam 16, and the second connecting beam 14 and the third connecting beam 16 are not on the same plane, which allows the controller mounting surface 3 to tilt inward toward the vehicle body, making the installation of the controller and the battery more compact.

[0040] In this embodiment, the support body is an integral structure.

[0041] like Figure 7 and Figure 8As shown, the bracket support plate 2 is provided with two bracket mounting holes 20. The bracket body is installed on the wheel cover by bolts. In order to further improve the stability of the bracket support plate 2 installation, a bracket side mounting plate 21 is provided on the side of the controller mounting surface 3. The bracket side mounting plate 21 is provided with bracket side mounting holes 22. The bracket body is further fixed by bolts.

[0042] When using, such as Figure 9 and Figure 10 As shown, follow these steps to install:

[0043] Step ① The common bracket is installed on the wheel cover 27 by bolts;

[0044] Step ② Controller 26 is fixed to the common bracket by bolts;

[0045] Step ③ The battery bracket 25 is installed on the vehicle floor 24 with bolts, but not tightened.

[0046] Step 4: Push the battery 23 forward from the rear of the vehicle body to secure it in the battery mounting slot 7 of the common bracket;

[0047] Step 5: Secure the battery bracket and common bracket to the surface where the battery mounting slot is located, and tighten them firmly to the vehicle floor. The structure after installation is as follows: Figure 10 As shown.

[0048] Example 2

[0050] Secure the bracket body to the rear wheel arch and the controller to the bracket body; install the battery bracket on the vehicle floor with bolts, but do not tighten it; push the battery forward from the rear of the vehicle to lock it into the common bracket slot; secure the battery bracket and common bracket through the slot and tighten them to the vehicle floor.

[0051] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
