Abstract
Description
Technical Field
[0001] This application relates to the field of automotive battery maintenance plate installation, and in particular to integrated maintenance plate mounting beams. Background Technology
[0002] The specific roles vary slightly depending on the type of electric vehicle. In pure electric vehicles equipped solely with a battery, the battery serves as the sole power source for the vehicle's drive system. In hybrid electric vehicles, which combine a conventional engine and a battery, the battery can function as both the primary and auxiliary power source for the drive system. Specifically, at low speeds and during startup, the battery acts as the primary power source; during full-load acceleration, it functions as an auxiliary power source; and during normal driving, deceleration, or braking, it serves as an energy storage device.

[0011] By adopting the above technical solution, when the maintenance plate moves, the buffers at its four corners will deform. When it passes over an obstacle, the maintenance plate will return to its original position through the restoring thrust of the buffers.
[0012] Preferably, there are four buffer components, located at the four corners of the mounting beam, with the lower part of each buffer component abutting against the four corners of the upper surface of the maintenance plate. The buffer components are made of natural rubber.

[0018] Preferably, the inner plate has a heat dissipation groove on its upper part, and the inner plate is located above the maintenance plate.
[0019] By adopting the above technical solution, the heat generated by the battery pack can be directed between the maintenance board and the battery pack, which can achieve slight heat dissipation and increase the heat dissipation space of the battery pack.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. In this application, the force applied to restrict the maintenance plate by the connection of nuts and fastening bolts is a squeezing force. If the maintenance plate receives a large impact force, the impact force at the bottom will push the maintenance plate to move upward. The maintenance plate will drive the connecting parts and fastening bolts to move upward. The fastening bolts will move inside the through groove and move from inside the through groove to the top. When the maintenance plate moves, the buffer parts at its four corners will deform. When it passes over the obstacle, the maintenance plate will return to its original position through the restoring thrust of the buffer parts.
[0022] 2. This application uses nuts and fastening bolts to restrict the maintenance plate. At this time, the upper surface of the maintenance plate is in contact with the lower surface of the buffer. During the movement of the vehicle, the force applied to restrict the maintenance plate by the nut and fastening bolt is a squeezing force. If the maintenance plate receives a large impact force, the impact force at the bottom will push the maintenance plate to move upward. The maintenance plate will drive the connecting parts and fastening bolts to move upward. The fastening bolts will move inside the through groove and move from inside the through groove to the top. When the maintenance plate moves, the buffer at its four corners will deform. When it passes over an obstacle, the restoring thrust of the buffer will make the maintenance plate return to its original position. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0030] This application discloses an integrated maintenance plate mounting beam, including a mounting beam plate 1. A movable area 2 is formed on the lower inner side of the mounting beam plate 1. A maintenance plate 3 is mounted on the lower inner side of the mounting beam plate 1 below the movable area 2. A connector 4 is mounted on the maintenance plate 3. A limiting groove 6 is formed on the inner side of the mounting beam plate 1. A through groove 7 is formed on the inner side of the limiting groove 6. A fastening bolt 8 is mounted on the upper part of the connector 4. One end of the fastening bolt 8 is threadedly connected to a nut 5. The side of the nut 5 abuts against the outer side of the mounting beam plate 1. Connectors 4 are mounted on both sides of the mounting beam plate 1. The extension plate 12 has multiple mounting bolts evenly arranged on it. The width of the connector 4 is matched with the width of the limiting groove 6. The connector 4 is located inside the limiting groove 6 and can move inside the limiting groove 6. When the maintenance plate 3 receives a large impact force, the impact force at the bottom will push the maintenance plate 3 to move upward. The maintenance plate 3 will drive the connector 4 and the fastening bolt 8 to move upward. The fastening bolt 8 will move inside the through groove 7 and move from inside the through groove 7 to the upper part. When the maintenance plate 3 moves, the buffer 11 at its four corners will deform and play a buffering role.
[0031] Screws 9 are installed at the four corners of the mounting beam plate 1. The mounting beam plate 1 is connected to the fixing plate 10 by the screws 9. Buffer members 11 are installed at the lower part of the fixing plate 10. There are four buffer members 11, located at the four corners of the mounting beam plate 1, and the lower part of the buffer members 11 abuts against the four corners of the upper surface of the maintenance plate 3. The buffer members 11 are made of natural rubber. The pushing force of the buffer members 11 is greater than the squeezing force generated when the nut 5 and the fastening bolt 8 are connected. Natural rubber is an isoprene polymer with excellent resilience and tensile strength, and is suitable for making shock-absorbing and buffer parts.
[0032] A connecting rod 13 is installed on the inner side of the mounting beam plate 1. The mounting beam plate 1 is connected to the inner plate 14 through the connecting rod 13. A heat dissipation groove 15 is provided on the upper part of the inner plate 14. The inner plate 14 is located above the maintenance plate 3, so that the heat generated by the battery pack can enter between the maintenance plate 3 and the battery pack, which can dissipate heat slightly and improve the heat dissipation space of the battery pack.
[0033] The implementation principle of the integrated maintenance plate mounting beam in this application embodiment is as follows: During installation, the battery pack is placed inside the inner plate 14. Through the heat dissipation groove 15 opened on the inner plate 14, the heat generated by the battery pack enters between the maintenance plate 3 and the battery pack, which can dissipate heat slightly and increase the heat dissipation space of the battery pack. Then, the mounting beam plate 1 is fixed by multiple mounting bolts evenly arranged on the extension plate 12 and installed at the bottom of the car.
[0034] When installing the maintenance plate 3, align the connecting piece 4 and the limiting groove 6 on the maintenance plate 3 vertically, and gradually push the maintenance plate 3 upwards so that the connecting piece 4 enters the interior of the limiting groove 6. When the connecting piece 4 drives the fastening bolt 8 to align with the lowest part of the through groove 7, stop moving and push the fastening bolt 8 into the lowest part of the through groove 7, with one end of the fastening bolt 8 passing through the through groove 7. The nut 5 connects to the fastening bolt 8, restricting the maintenance plate 3. At this time, the upper surface of the maintenance plate 3 contacts the lower surface of the buffer 11. When the car is moving... During the process, the force applied to the maintenance plate 3 by the connection of nut 5 and fastening bolt 8 is a squeezing force. If the maintenance plate 3 receives a large impact force, the impact force at the bottom will push the maintenance plate 3 to move upward. The maintenance plate 3 will drive the connecting piece 4 and fastening bolt 8 to move upward. The fastening bolt 8 will move inside the through groove 7 and move from inside the through groove 7 to the upper part. When the maintenance plate 3 moves, the buffer piece 11 at its four corners will deform. When it passes over the obstacle, the maintenance plate 3 can be restored to its original position by the restoring thrust of the buffer piece 11.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
