[0016] Due to the adoption of the above technical scheme, the application has the following beneficial effects:

[0017] 1. This application utilizes a support structure between two adjacent longitudinal beams. This support structure provides support to the two beams, improving the structural strength of the vehicle's rear suspension module and enhancing vehicle stability. By fixing the battery to the support structure, the battery avoids occupying space on both sides of the vehicle, facilitating cargo loading and unloading and the installation of auxiliary devices. Simultaneously, the spare tire lifter is fixed to the support structure and connected to the spare tire. This allows the support structure to simultaneously secure both the battery and spare tire, avoiding the space waste caused by separately securing the spare tire and battery, thus improving vehicle space utilization. During the production stage, the support structure simplifies the assembly process of the battery and spare tire, reducing installation steps and time, improving production efficiency, and lowering production costs. Furthermore, the support structure concentrates the battery and spare tire in a relatively centralized location, facilitating later inspection and maintenance.

[0018] 2. As a preferred embodiment of this application, a support plate is provided to offer installation space for the battery, increasing the contact area between the battery and the support structure and enhancing the support structure's ability to support the battery. The side plate serves two purposes: firstly, it limits the battery's position in the vehicle's axial direction, preventing it from moving out of the support plate during vehicle operation; secondly, it provides a fixed position for the spare tire lifter, offering stable support. Simultaneously, the side plate divides the space, making the battery space relatively independent from the spare tire lifter space, avoiding interference during operation. The battery is secured by locking components, ensuring its stable mounting on the support plate and guaranteeing a stable power supply.

[0019] 3. In a preferred embodiment of this application, two positioning members are provided. The pressure plate is connected to the two positioning members by two connecting members. The two positioning members provide accurate positioning for the pressure plate, improving its contact with the battery at the designated position. The pressure plate can move along the connecting members, and the locking member can adapt to batteries of different sizes. By adjusting the position of the pressure plate, it can be flexibly adjusted according to the thickness, width, and other parameters of the actual battery to achieve the best fixing effect, increasing the versatility and applicability of the support structure. The connecting members can fix the pressure plate, keeping it in contact with the battery, facilitating quick release of the pressure plate when the battery needs to be inspected or replaced. When installing the battery, after the pressure plate reaches the appropriate position, it is firmly fixed by fixing it with the connecting members. When removing the battery, simply loosen the connecting members and move the pressure plate to remove the battery, improving the convenience of maintenance operations and saving maintenance time and labor costs.

[0020] 4. In a preferred embodiment of this application, the positioning component is provided with a positioning hole. One end of the connecting rod passes through the through hole and is threadedly connected to the fastening ring, while the other end is bent to engage with the positioning hole. This allows the pressure plate to be accurately aligned with the positioning component during installation, achieving precise positioning. Simultaneously, when the pressure plate moves to the corresponding position, the bent end of the connecting rod can be quickly disengaged from the positioning hole, facilitating the removal of the battery. Furthermore, by providing a threaded connection between the connecting rod and the fastening ring, the position of the pressure plate can be easily adjusted by rotating the fastening ring during battery installation or adjustment to accommodate batteries of different sizes or models.

[0021] 5. As a preferred embodiment of this application, by providing a fixed plate that is fixedly connected to the longitudinal beam, the connection between the support structure and the longitudinal beam is made more stable. At the same time, by providing a fixed plate, the connection requirements between the side plates and the support plate and the longitudinal beam are reduced. By providing reinforcing members, including vertical connecting members and horizontal connecting members, the reinforcing members further improve the connection strength between the fixed plate and the side plates and the support plate, thereby improving the overall structural strength of the support structure.

[0022] 6. As a preferred embodiment of this application, by setting a limiting plate, the support plate is partitioned, which divides the support plate into multiple battery installation positions, providing precise positioning for battery installation. At the same time, the limiting plate can control the distance between two adjacent batteries, so that the batteries are reasonably distributed on the support plate and the heat dissipation capacity of the batteries is improved.

[0023] Furthermore, by incorporating multiple heat dissipation holes in the support plate, the heat dissipation capacity of the support plate is further improved, facilitating heat dissipation from the battery. Simultaneously, the heat dissipation holes reduce the weight of the support structure, simplifying production and installation, and lowering production costs.

[0024] 7. As a preferred embodiment of this application, the connecting crossbeam is detachably mounted on the two longitudinal beams, which facilitates maintenance and replacement of components. At the same time, the connecting crossbeam can provide good support for the longitudinal beams, further improving the structural strength of the vehicle's rear suspension module.

[0025] Furthermore, by setting an auxiliary crossbeam, the structural strength of the vehicle's rear suspension module is improved by providing stable support for the longitudinal beam. One end of the spare tire lifter housing is connected to the support structure, and the other end is connected to the auxiliary crossbeam. The auxiliary crossbeam and support structure disperse the weight of the spare tire and the forces generated during vehicle operation, thereby improving the vehicle's driving stability. At the same time, the spare tire can be raised and lowered more stably.

[0026] In an embodiment, the driving part comprises a driving rod, and the connecting beam is provided with a limiting hole matched with the driving rod. The limiting hole provides positioning for the driving rod, facilitating installation and maintenance of the driving rod, and provides stable support for the driving rod, so that the driving rod can stably drive the spare tire to rise and fall.

[0046] ​The application sets the support structure 3 between the two adjacent longitudinal beams 2, which can provide support for the two adjacent longitudinal beams 2, improve the structural strength of the vehicle rear suspension module, and improve the stability of the vehicle operation. By fixing the storage battery 4 to the support structure 3, the storage battery 4 can avoid occupying the space on both sides of the vehicle, facilitating the loading and unloading of the carried goods and the installation of auxiliary devices.

Those skilled in the art can clearly see that the spare tire lifter 5 can also be arranged on the side plate on the rear side of the support plate 31.

[0049] By setting the support plate 31 to provide mounting space for the storage battery 4, the contact area of the storage battery 4 and the support structure 3 is improved, and the support capacity of the support structure 3 to the storage battery 4 is improved. By setting the side plate 32, on the one hand, the storage battery 4 is limited in the vehicle axial direction, avoiding the storage battery 4 moving out of the support plate 31 during vehicle operation, and on the other hand, the side plate 32 provides a fixing position for the spare tire lifter 5, which provides stable support for the spare tire lifter 5 through the side plate 32. At the same time, the side plate 32 plays a role in dividing the area, making the space of the storage battery 4 and the space of the spare tire lifter 5 relatively independent, avoiding interference during operation.

The pressing plate 331 is connected to the two positioning members 332 through two connecting members 333, respectively. The pressing plate 331 is movable along the connecting member 333, and is used to abut against the battery 4. The connecting member 333 can fix the pressing plate 331 to keep the pressing plate 331 abutting against the battery 4. By arranging two positioning members 332, the pressing plate 331 is connected to the two positioning members 332 through two connecting members 333, respectively. The two positioning members 332 provide accurate positioning for the pressing plate 331, improving the abutment of the pressing plate 331 at the set position of the battery 4.

At the same time, when the abutting plate 331 moves to the corresponding position, the end of the connecting rod 3331 can be quickly separated from the positioning hole 3321, which is more convenient for moving out the storage battery 4. Moreover, by screwing the connecting rod 3331 with the fastening ring 3332, when installing or adjusting the fixed position of the storage battery 4, the position of the abutting plate 331 can be easily adjusted by rotating the fastening ring 3332 to adapt to storage batteries 4 of different sizes or models.
