Two storage batteries can be placed in the "sun-shaped" (Japanese-shaped) structure, and the arrangement of the plurality of through holes allows adjustment of the positions of the clamping pieces in two directions, so as to be suitable for clamping storage batteries of different sizes and specifications.

[0005] Fixed seats are fixedly connected to both sides of the bottom plate, a screw rod is vertically threadedly connected to the middle part of the fixed seat, a pressure rod is inserted on the screw rod, and a preset nut on the screw rod presses against the pressure rod. By screwing the nut downward, the pressure rod presses down the preset storage battery below, so as to realize fixing the storage battery in the vertical direction. In addition, in cooperation with the function of the clamping pieces in two directions, the clamping and fixing of six surfaces of the storage battery is realized, which improves the stability of the storage battery during vibration testing.

[0006] Preferably, the clamping component includes a fixing plate and a clamping plate. A guide bolt is inserted through the fixing plate, and the end of the guide bolt is threadedly connected to a nut pre-installed on the clamping plate. A limit bolt is threadedly connected to the fixing plate, and the other end of the limit bolt abuts against the clamping plate. The guide bolt makes the fixing plate and the clamping plate a single unit. Furthermore, rotating the limit bolt moves the clamping plate away from the fixing plate, thus clamping and fixing the battery.

[0007] Preferably, the threaded hole that mates with the limiting bolt is open, and clamping bolts are threadedly connected to both sides of the upper end of the fixing plate, with the clamping bolts passing through the opening. After the limiting bolt has finished moving, the clamping bolts are rotated to lock the limiting bolt in place, greatly reducing the probability of the limiting bolt loosening during vibration testing.

[0008] Preferably, the bottom of the base plate is provided with a plurality of second fixing members, and the second fixing members are located above the lower end face of the base plate. The second fixing members are provided with threaded holes, and fixing bolts are inserted through both sides of the fixing plate, with the fixing bolts engaging with the threaded holes. The number and position of the threaded holes correspond to the pre-set through holes on the base plate, enabling the fixing bolts to pass through the base plate and be fixedly connected to the threaded holes. Changing the position of the clamping member allows the fixing bolts to engage with the threaded holes at the corresponding positions. Further, the second fixing members are of two types: one is fixedly connected to the clamping member, and the other is fixedly connected to the fixing seat.

[0009] Preferably, the base plate is provided with a plurality of first fixing members, and the upper end surface of the first fixing members is not higher than the upper end surface of the base plate. The first fixing members are used to fix the base plate to the test platform.
