[0001] This utility model relates to the field of battery mounting bracket technology, and in particular to a stable mounting bracket for power battery packs. Background Technology

[0002] With the development of the times, new energy vehicles, energy storage systems and other fields have developed rapidly. In electric vehicles or hybrid vehicles, power battery packs composed of multiple individual batteries are generally used to meet the demand for high power output. Power battery pack mounting brackets have emerged in this context.

[0003] Traditional brackets are not easy to position during battery installation, so operators need to spend a lot of time adjusting the battery position to match the installation location, making the installation process cumbersome and time-consuming. In addition, the connection method of traditional brackets is relatively complex, and there is a lack of effective coordination between the connection points. During long-term use, the connections are prone to loosening, which leads to a decrease in the overall stability of the battery pack.

[0004] Therefore, those skilled in the art have provided a robust mounting bracket for power battery packs to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a stable mounting bracket for power battery packs. When installing the battery body, the battery body is simply slid into the inner wall of the main frame along the sliding grooves on both sides to establish an initial connection with the main frame. During this process, the rear end of the battery body is held in place by a connecting piece. Then, the connecting plate is installed by first engaging the insert plate with the slot, at which point the connecting slot will engage with the front end of the battery body. Finally, by rotating the connecting screw sleeve with a tool, the connecting plate can be firmly secured to the main frame. In this way, the battery body can be installed quickly.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A power battery pack mounting bracket includes a main body assembly, which includes a main frame. A connecting component is provided at the front end of the main frame. The connecting component includes a connecting plate. Multiple fixing slots are provided at the rear end of the inner wall of the main frame. Connecting plates are slidably connected to both sides of the inner wall of the fixing slots. Multiple return springs are fixedly connected to the front end of the inner wall of the fixing slots. Connecting seats are fixedly connected to the middle of the front ends of both sides of the outer wall of the main frame and the middle of both sides of the outer wall of the connecting plate.

[0008] Insert plates are fixedly connected to both sides of the rear end of the outer wall of the connecting plate. Slots are opened on both sides of the front end of the outer wall of the main frame. Threaded rods are fixedly connected to one end of the connecting seat on the main frame. Connecting screw sleeves are provided on both sides of the outer front end of the connecting plate. Multiple connecting slots are opened at the rear end of the connecting plate. Multiple sliding grooves are opened on both sides of the inner wall of the main frame.

[0009] With the above technical solution, when installing the battery pack mounting bracket, the battery body can be initially connected to the main frame simply by sliding the two sides of the battery body into the inner wall groove. During this process, the rear end of the battery body will be held in place by the connecting piece. Then, the connecting plate is installed. First, the insert plate is engaged with the slot. At this time, the connecting slot will be engaged with the front end of the battery body. Finally, by rotating the connecting screw sleeve with a tool, the connecting plate can be firmly fastened to the main frame. In this way, the battery body can be installed quickly.

[0010] Furthermore, the inner wall of each groove is provided with a battery body, the rear end of each battery body is attached to the outer wall of the connecting piece, and the front end of each battery body is attached to the inner wall of the connecting groove.

[0011] The above technical solution enables the battery body to be stably installed in the slide, effectively ensuring the stability of the power supply of the entire device, and also facilitating the installation and replacement of the battery.

[0012] Furthermore, each of the fixing grooves is connected to the corresponding sliding groove;

[0013] Through the above technical solution, this through-type design facilitates the connection and fixation of other components with the battery body or related structures in the chute, thereby improving production efficiency and product quality.

[0014] Furthermore, the other end of each threaded rod passes through the connecting seat on the connecting plate and is fastened by a connecting threaded sleeve;

[0015] The above technical solution utilizes the cooperation between the threaded rod and the connecting sleeve to adjust the relative position between the connecting plate and the main frame, thereby enabling flexible control of the internal spatial layout of the device. Furthermore, the connection and fastening method is simple and easy to implement, facilitating disassembly and maintenance.

[0016] Furthermore, the rear end of each connecting piece is fixedly connected to the front end of multiple return springs, and multiple ventilation slots are provided on both sides of the outer wall of the main frame.

[0017] Through the above technical solution, the reset spring can provide a certain elastic buffer force for the connecting piece, which can effectively extend its service life, while the ventilation slot is conducive to the air circulation inside the device, timely dissipating the heat generated during battery operation, avoiding battery performance degradation or safety accidents due to overheating, and ensuring that the device can operate stably in a suitable temperature environment.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figure 1-5 One specific embodiment provided by this utility model:

[0031] A power battery pack mounting bracket includes a main component 1, which includes a main frame 101. A connecting component 2 is provided at the front end of the main frame 101. The connecting component 2 includes a connecting plate 201. Multiple fixing grooves 107 are provided at the rear end of the inner wall of the main frame 101. Connecting pieces 109 are slidably connected to both sides of the inner wall of the fixing groove 107. Multiple return springs 108 are fixedly connected to the front end of the inner wall of the fixing groove 107. Connecting seats 204 are fixedly connected to the middle of the front ends of both sides of the outer wall of the main frame 101 and the middle of both sides of the outer wall of the connecting plate 201.

[0032] Insert plates 203 are fixedly connected to both sides of the rear end of the outer wall of the connecting plate 201. Slots 103 are opened on both sides of the front outer wall of the main frame 101. Threaded rods 105 are fixedly connected to one end of the connecting seat 204 on the main frame 101. Connecting screw sleeves 106 are provided on both sides of the outer front end of the connecting plate 201. Multiple connecting slots 202 are opened at the rear end of the connecting plate 201. Multiple sliding grooves 104 are opened on both sides of the inner wall of the main frame 101.

[0033] When installing the battery body 3, the battery mounting bracket simply slides the two sides of the battery body 3 into the inner wall of the main frame 101 through the sliding grooves 104 to establish a preliminary connection with the main frame 101. During this process, the rear end of the battery body 3 will be held in place by the connecting piece 109. Then, the connecting plate 201 is installed. First, the insert plate 203 is engaged with the slot 103. At this time, the connecting slot 202 will be engaged with the front end of the battery body 3. Finally, by rotating the connecting screw sleeve 106 with a tool, the connecting plate 201 can be firmly fastened to the main frame 101. In this way, the battery body 3 can be installed quickly.

[0034] The inner wall of the slide 104 is provided with a battery body 3. The rear end of the battery body 3 is attached to the outer wall of the connecting piece 109, and the front end of the battery body 3 is attached to the inner wall of the connecting groove 202. This allows the battery body 3 to be stably installed in the slide 104, effectively ensuring the stability of the power supply of the entire device. It also facilitates the installation and replacement of the battery. The fixing groove 107 is connected to the corresponding slide 104. This through design facilitates the connection and fixation of other components with the battery body 3 or related structures in the slide 104, improving production efficiency and product quality.

[0035] The other end of the threaded rod 105 passes through the connecting seat 204 on the connecting plate 201 and is fastened by the connecting screw sleeve 106. By using the cooperation between the threaded rod 105 and the connecting screw sleeve 106, the relative positional relationship between the connecting plate 201 and the main frame 101 can be adjusted, realizing flexible control of the internal spatial layout of the device. Moreover, the connection and fastening method is simple and easy to implement, and easy to disassemble and maintain. The rear end of the connecting piece 109 is fixedly connected to the front end of multiple return springs 108. Multiple ventilation slots 102 are opened on both sides of the outer wall of the main frame 101. The return springs 108 can provide a certain elastic buffer force for the connecting piece 109, which can effectively extend its service life. The ventilation slots 102 are conducive to the air circulation inside the device, timely dissipating the heat generated during the operation of the battery, avoiding battery performance degradation or safety accidents due to overheating, and ensuring that the device can operate stably in a suitable temperature environment.

[0036] Working principle: During installation, the battery body 3 is first slowly slid into the slide groove 104 on the inner wall of the main frame 101. Due to the guiding effect of the slide groove 104, the battery body 3 can enter the predetermined installation position. During the sliding process, the rear end of the battery body 3 begins to contact the connecting piece 109 in the fixing groove 107. Under the initial pre-tightening force of the return spring 108, the connecting piece 109 applies a certain resistance force to the rear end of the battery body 3.

[0037] After the battery body 3 is basically in place, the connecting plate 201 is installed. The insert plate 203 at the rear end of the connecting plate 201 is aligned with the slot 103 on the outer wall of the front end of the main frame 101 and inserted to achieve initial positioning and connection. At this time, the connecting slot 202 at the rear end of the connecting plate 201 corresponds to and engages with the front end of the battery body 3, further limiting the battery body 3 from the front end. Next, the threaded rod 105 of the connecting seat 204 on the main frame 101 is passed through the corresponding connecting seat 204 on the connecting plate 201, and then the connecting screw sleeve 106 is rotated to connect the battery body 3. As the connecting plate 201 gradually approaches and tightens towards the main frame 101, the movement of the connecting plate 201 will push the battery body 3 to move slightly towards the front end, while the rear end of the battery body 3 will squeeze the connecting piece 109. The connecting piece 109 will overcome the elastic force of the return spring 108 and move backward until the connecting plate 201 is tightly fixed to the main frame 101. At this time, the return spring 108 is in a compressed state and will continue to apply a backward force to the connecting piece 109. This force works in conjunction with the limiting force of the connecting groove 202 on the front end of the battery body 3.
