In the claims, specification, and drawings of the present invention, terms such as "including," "having," and their variations are intended to mean "including but not limited to."
[0034] Please also refer to Figures 1 to 4The power battery mounting structure and vehicle provided by the present invention are now described. The power battery mounting structure includes a plurality of mounting brackets 1 connected sequentially along the vertical direction. Each mounting bracket 1 includes a plurality of mounting positions 104 distributed sequentially along a first path. The mounting positions 104 are used to accommodate a battery pack 3. The first path is perpendicular to the vertical direction. The mounting brackets 1 include a support plate 101 and a plurality of partition plates 102. The support plate 101 is used to provide support for the battery pack 3. The plurality of partition plates 102 are spaced apart from the support plate 101 along the first path. The mounting positions 104 are formed between two adjacent partition plates 102. The partition plates 102 are also connected to the support plates 101 of adjacent mounting brackets 1.
[0035] Compared with the prior art, the power battery mounting structure provided by the present invention includes a plurality of fixing frames 1 distributed in the vertical direction, and each fixing frame 1 has a plurality of mounting positions 104 for accommodating battery packs 3. Users can determine the number of battery packs 3 according to the battery life requirements, and thus select the corresponding number of fixing frames 1. The battery packs 3 are placed on the support plate 101, and the partition plate 102 provides support for the fixing frame 1 and the battery pack 3 above. The mounting position 104 is formed between two adjacent partition plates 102, which can increase the support performance of the battery pack 3 and the support plate 101 above, and prevent the support plate 101 from being deformed by the gravity of the battery pack 3. The connection of multiple fixing frames 1 is achieved by a stacked installation method, which can reduce the space occupied. The present invention can flexibly select the number of fixing frames 1 according to the number of battery packs 3, without the need to set up a dedicated mounting structure in a targeted manner. It has versatility, reduces manufacturing and design costs, and can meet the different battery life requirements of users.
[0036] Optionally, the partition plate 102 is welded, screwed or clamped to the upper support plate 101 .
[0037] It should be noted that the present invention only distributes multiple partition plates 102 at intervals along the first path to provide support for the upper fixing frame 1 and the battery pack 3. Compared with the solution of evenly distributing the partition plates 102 on the periphery of the battery pack 3 in the prior art, it is beneficial to quickly dissipate the heat generated by the battery pack 3.
[0038] Optionally, the support plate 101 includes a support body 1011 and a mounting beam 1012 disposed on the support body 1011. The partition plate 102 is connected to the support body 1011, and the battery pack 3 is mounted on the mounting beam 1012. The mounting beam 1012 creates a space between the bottom of the battery pack 3 and the support body 1011, which facilitates heat dissipation from the bottom of the battery pack 3.
[0039] In some embodiments, see Figure 1 and Figure 3, multiple fixing frames 1 are connected in sequence to form a support assembly, and the power battery installation structure also includes a protective plate 2 arranged on the top of the support assembly, and the protective plate 2 is used to shield the battery pack 3.
[0040] With the exception of the top battery pack 3, all other battery packs 3 are shielded by the upper support plate 101 and the outer perimeter by the partition plate 102, thereby reducing the risk of damage from external forces. The installation of a protective plate 2 on top of the support assembly prevents the top surface of the top battery pack 3 from being exposed to the outside, which could lead to damage from external forces, thereby increasing the service life of the battery pack 3. Furthermore, the solution in this embodiment can also be equipped with other components on the protective plate 2, facilitating a rational layout of the vehicle.
[0041] In some embodiments, see Figure 1 and Figure 3 The power battery mounting structure also includes a shock-absorbing assembly 4 connected to the bottom fixing frame 1. The shock-absorbing assembly 4 includes a connecting seat 401, a locking member 402 and a shock-absorbing pad 403. The connecting seat 401 is connected to the bottom fixing frame 1 and extends outward from the fixing frame 1; the locking member 402 is inserted into the connecting seat 401 for connecting to the vehicle body; the shock-absorbing pad 403 is sleeved outside the locking member 402 for alleviating the vibration force between the connecting seat 401 and the vehicle body.
[0042] The locking member 402 is inserted into the connecting seat 401 to fix the connecting seat 401 to the vehicle body. Compared with the solution of directly connecting the locking member 402 to the fixing frame 1, it not only increases the contact area with the vehicle body, but also makes the installation position 104 more flexible.
[0043] Optionally, the shock-absorbing pad 403 is an elastic or flexible component, such as a rubber component, an EVA component, etc.
[0044] Optionally, the connecting seat 401 includes a connecting plate connected to the fixing frame 1 and reinforcement plates located on opposite sides of the connecting plate, the reinforcement plates are used to increase the strength and deformation resistance of the connecting plate, and the locking member 402 is inserted into the connecting plate.
[0045] In some embodiments, see Figure 1 and Figure 3 There are multiple shock absorbing components 4, and the multiple shock absorbing components 4 are respectively connected to the outer periphery of the bottom fixing frame 1.
[0046] This embodiment connects the mounting bracket 1 to the vehicle body by providing multiple sets of damping assemblies 4. This increases the number of connection points for the mounting bracket 1, improving both reliability and stability while also reducing the pressure at each connection point. Compared to solutions that incorporate integral damping assemblies 4 around the perimeter of the mounting bracket 1, this embodiment reduces the overall weight of the power battery mounting structure, ultimately contributing to a lighter vehicle.
[0047] In some embodiments, see Figure 1 The power battery installation structure also includes a lifting ring 5 that is detachably connected to the partition plate 102.
[0048] The lifting ring 5 is detachably connected to the partition plate 102. When installing the battery pack 3, the battery pack 3 can be first connected to the corresponding fixing frame 1 to form an installation module, and then the lifting ring 5 can be hung using a lifting device to connect multiple installation modules in sequence. In this embodiment, the battery pack 3 and the fixing frame 1 can be fixed first, and then assembled. Compared with the solution of first connecting multiple fixing frames 1 in sequence and then installing the battery pack 3, the installation of the battery pack 3 is more convenient and avoids the problem of wasting manpower during the transportation of the installation module. In addition, after the power battery installation structure is formed, the entire power battery installation structure can be placed in the corresponding position of the vehicle body through the lifting ring 5 to facilitate connection with the vehicle body.
[0049] Optionally, the lifting ring 5 can be installed on the outside of the partition plate 102, which is convenient for removing the lifting ring 5 after the lifting is completed. Optionally, the lifting ring 5 can also be installed on the top of the partition plate 102. When the fixing frame 1 is placed in the specified position, the lifting ring 5 is removed to avoid interference with the fixing frame 1 above.
[0050] In some embodiments, see Figures 3 and 4 The support plate 101 is provided with a heat dissipation module, and the heat dissipation modules are arranged in a one-to-one correspondence with the mounting positions 104 , and each heat dissipation module includes at least one heat dissipation hole 1013 .
[0051] The battery pack 3 generates a large amount of heat during operation. Providing a heat dissipation module is beneficial for quickly dissipating the heat generated by the battery pack 3 to prevent heat accumulation from affecting the normal operation of the battery pack 3.
[0052] In some embodiments, see Figure 4 The partition plate 102 includes a crossbeam 1022 and a plurality of columns 1021. The plurality of columns 1021 are distributed on the support plate 101 in sequence along the second path, and a heat dissipation space is formed between two adjacent columns 1021. The second path is perpendicular to the first path; the crossbeam 1022 is connected to the plurality of columns 1021 in sequence, and the crossbeam 1022 is also connected to the support plate 101 of the adjacent fixed frame 1.
[0053] Multiple columns 1021 are connected to beams 1022 to form an integrated structure. Compared to designs in which the partition plate 102 is an integral plate, this embodiment not only ensures support for the upper fixing frame 1 and battery pack 3, but also creates a heat dissipation space between two adjacent columns 1021, which can quickly dissipate heat generated by the battery pack 3, preventing heat accumulation from causing alarms or damage to the battery pack 3.
[0054] Optionally, the crossbeam 1022 is connected to the top of the column 1021 and is connected to the support plate 101 above.
[0055] In some embodiments, see Figure 4 The partition plate 102 further includes a reinforcing plate 1023 connected to the column 1021 , and a weight-reducing groove is provided in the middle portion of the reinforcing plate 1023 .
[0056] The reinforcing plate 1023 can increase the strength of the partition plate 102, and a weight-reducing groove is opened in the center of the reinforcing plate 1023, which not only ensures the contact area between the reinforcing plate 1023 and the column 1021, the support plate 101 and the beam 1022, ensuring the firmness of the connection, but also reduces the weight, and is also beneficial to the heat dissipation of the battery pack 3.
[0057] Optionally, the side of the reinforcing plate 1023 is provided with an opening connected to the weight-reducing slot, forming a "U"-shaped structure of the reinforcing plate 1023. This solution in this embodiment further reduces the deadweight of the reinforcing plate 1023 and improves the heat dissipation effect of the battery pack 3 while ensuring a reliable connection between the reinforcing plate 1023 and surrounding components.
[0058] In some embodiments, see Figure 2 The fixing frame 1 further includes a reinforcing block 103 connected to the partition plate 102 , and the reinforcing block 103 and the partition plate 102 jointly provide supporting force for the supporting plate 101 .
[0059] The reinforcement block 103 and the partition plate 102 jointly provide support force to the support plate 101 , thereby increasing the contact area with the support plate 101 , reducing the pressure at the support points, and improving the reliability of the support plate 101 .
[0060] Optionally, the reinforcement block 103 is a triangular structure, and the triangle has stability and improves the supporting effect.
[0061] Based on the same inventive concept, the present invention further provides a vehicle, which includes the above-mentioned power battery mounting structure.
[0062] The vehicle provided by the present invention adopts the above-mentioned power battery installation structure, which includes a plurality of fixing frames 1 distributed in the up-down direction, and each fixing frame 1 has a plurality of installation positions 104 for accommodating battery packs 3. Users can determine the number of battery packs 3 according to the battery life requirements, and thus select the corresponding number of fixing frames 1. The battery pack 3 is placed on the support plate 101, and the partition plate 102 provides support for the upper fixing frame 1 and the battery pack 3. The installation position 104 is formed between two adjacent partition plates 102, which can increase the support performance of the upper battery pack 3 and the support plate 101, and prevent the support plate 101 from being deformed by the gravity of the battery pack 3. The connection of multiple fixing frames 1 is achieved by a stacked installation method, which can reduce the space occupied. The utility model can flexibly select the number of fixing frames 1 according to the number of battery packs 3, without the need to set up a dedicated installation structure in a targeted manner. It has versatility, reduces manufacturing and design costs, and can meet the different battery life requirements of users.
