The existing pallet is equipped with a clamping mechanism for clamping a row of power batteries for assembly. When the power battery module is composed of two rows of power batteries, this type of pallet cannot meet the use requirements. Therefore, how to design a pallet that can meet the requirements of clamping and assembling two rows of power batteries has become a technical problem that needs to be solved urgently. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a double clamping structure tray to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] According to one aspect of the utility model, a double-clamping structure pallet is designed, comprising: a bottom plate and two clamping mechanisms longitudinally arranged on the bottom plate, wherein the clamping mechanism on the rear side of the two clamping mechanisms is fixedly connected to the bottom plate, and the clamping mechanism on the front side is longitudinally slidably matched with the bottom plate through a longitudinal guide component, and the clamping mechanism comprises a base, a first mounting seat and a second mounting seat, and two bakelite strips are inherently fixed to the top of the base in a transverse manner, the first mounting seat is transversely adjustably fixed to the left end of the base, a first clamping block is fixedly connected to the right end of the first mounting seat, the second mounting seat is arranged at the right end of the base, and is transversely slidably matched with the base through a transverse guide component, a second clamping block is provided at the left end of the second mounting seat, the second clamping block corresponds to the first clamping block on the left and right, and a first clamping locking unit is fixedly connected to the bottom of the second mounting seat, and when the first clamping locking unit is started, the transverse guide component can be clamped to lock the movement of the second mounting seat.

[0006] By adopting the above technical solution, two clamping mechanisms are set up, each clamping mechanism can clamp a row of power batteries horizontally, and the two clamping mechanisms can clamp two rows of power battery packs to meet the assembly requirements of the power battery module composed of two rows of power batteries; in addition, the front clamping mechanism is designed to be a longitudinally sliding structure, and its distance from the rear clamping mechanism can be adjusted, which can meet the assembly requirements of power batteries with different longitudinal widths and improve the practicality of the tray.

[0007] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0008] In some embodiments, a second clamping and locking unit is fixedly connected to the bottom of the front clamping mechanism. When the second clamping and locking unit is activated, it can clamp the longitudinal guiding component to lock the movement of the front clamping mechanism. Thus, the movement of the front clamping mechanism can be locked, facilitating assembly.

[0009] In some embodiments, a return driving mechanism for driving the front clamping mechanism to automatically return is connected to the bottom of the front clamping mechanism. Buffer devices are fixedly connected to the front sides of the left and right ends of the bottom plate, and the buffer ends of the buffer devices face the base. In the initial state, the front clamping mechanism is located at the front side of the bottom plate. When the front clamping mechanism clamps the power battery, an external force causes it to move backward, so that the power battery on it contacts the power battery clamped by the rear clamping mechanism. After contact, the second clamping and locking unit is activated to lock the movement of the front clamping mechanism. When the two rows of power batteries are assembled and taken away, the second clamping and locking unit releases the locking of the front clamping mechanism. The front clamping mechanism automatically returns to the front side of the bottom plate under the drive of the return driving mechanism and abuts against the buffer end of the buffer device, playing a buffering role through the buffer device.

[0010] In some embodiments, the longitudinal guiding component includes a longitudinal guide rail and a longitudinal slider. The longitudinal guide rail is fixedly connected to the bottom plate, the longitudinal slider is fixedly connected to the bottom of the base, and is longitudinally slidably engaged with the longitudinal guide rail.

When the second clamping and locking unit is activated, it can clamp the longitudinal guide rail to lock the movement of the front clamping mechanism.

[0011] In some embodiments, the transverse guiding component includes a transverse guide rail and a transverse slider. The transverse guide rail is fixedly connected to the base, the transverse slider is fixedly connected to the bottom of the second mounting seat, and is transversely slidably engaged with the transverse guide rail. The first clamping and locking unit is fixedly connected to the bottom of the second mounting seat. When the first clamping and locking unit is activated, it can clamp the transverse guide rail to lock the movement of the second mounting seat.

[0012] In some embodiments, the first mounting seat is connected to the base by screws, and a plurality of threaded holes for adjusting the fixed position of the first mounting seat are horizontally spaced on the base.

[0013] In some embodiments, the second mounting seat includes a mounting plate, an E-shaped seat and a U-shaped seat fixedly connected to the mounting plate. A limiting component for restricting the movement of the second mounting seat is mounted on the U-shaped seat. When the clamping mechanism is in a non-clamping state, the first clamping and locking unit is not activated. In order to prevent the second mounting seat from moving left and right, a limiting component is provided to restrict the movement of the second mounting seat.

[0014] In some embodiments, the limiting component includes a sliding rod, a connecting rod, a spring, a T-shaped member, and a limiting hole. The two sliding rods are vertically slidably engaged with the U-shaped seat. The two ends of the connecting rod are correspondingly connected to the two sliding rods. The lower ends of the two sliding rods are connected to the T-shaped member. The spring is sleeved on the sliding rod, and the upper end of the spring abuts against the U-shaped seat, and the lower end abuts against the T-shaped member. The lower end of the T-shaped member is vertically slidably engaged with the through hole on the mounting plate. The limiting hole is provided on the base, and the lower end of the T-shaped member can be inserted into the limiting hole.

[0015] In some embodiments, the first clamping and locking unit and the second clamping and locking unit are pneumatic clamps or hydraulic clamps. A limiting block is fixedly connected to the right end of the base, and a stop bolt is fixedly connected to the limiting block. The stop bolt corresponds to the bottom plate on the second mounting seat left and right.

[0016] In some embodiments, the return driving mechanism includes a longitudinal rod, a connecting block, a return spring, and a driving block.

The driving block is fixedly connected to the base and is longitudinally slidably engaged with the two longitudinal rods. One end of the return spring elastically abuts against the driving block, and the other end elastically abuts against the rear connecting block of the two connecting blocks.

One end of the reset spring 83 is elastically abutted against the driving block 84, and the other end is elastically abutted against the connecting block 82 on the rear side of the two connecting blocks 82. Buffers 11 are respectively fixedly connected to the front sides of the left and right ends of the bottom plate 1, and the buffering end of the buffer 11 faces the base 21. When the front clamping mechanism 2 is in a state close to the rear clamping mechanism 2, the second clamping locking unit 7 clamps the longitudinal guide rail 31, and the return spring 83 is in a compressed state.
