Description

Technical Field

[0001] This utility model relates to the technical field of Z-axis clamping device on the circulating material rack of new energy battery packs, specifically a rotating pressure bar structure. Background Technology

[0002] During the logistics and transportation of battery packs, road bumps, sudden braking or acceleration of vehicles can all subject the battery packs loaded in the recycling racks to impact forces from different directions. When the vertical impact force is too large, the battery pack is prone to vertical jumping. This jumping can not only cause collisions and friction between battery packs, but may also cause internal cell displacement, loosening of connecting wires, and even damage to the battery pack casing, leading to serious safety hazards such as short circuits and fires. Utility Model Content

[0003] The purpose of this invention is to provide a rotating pressure bar structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotating pressure rod structure, comprising a rotating pressure plate, a pressure rod base, and a mounting base. The middle part of the top of the mounting base is fixedly welded to the bottom end of the pressure rod base. The pressure rod base has a pin fixing hole and a bushing through hole sequentially from top to bottom. A bushing is inserted into the bushing through hole, and one end of the bushing passes through the bushing through hole and is sleeved with a rotating pressure plate. The other end of the bushing is welded to the opening in the middle of the torsion spring fixing seat, and the torsion spring fixing seat is welded to the pressure rod base. One end of a right-handed torsion spring is fixedly connected to the torsion spring fixing seat, and the other end of the right-handed torsion spring is fixedly connected to the rotating pressure plate. A spring pin is fixedly welded inside the pin fixing hole. A pressure plate is mounted on the rotating pressure plate, and a rubber sleeve is adhesively fitted onto the outside of the pressure plate.

[0005] When the battery pack needs to be compressed, the mounting base is installed on the circulating material rack through the mounting holes and screws. Then, the rotating pressure plate is rotated so that the spring pin enters the pin insertion hole through the pin guide groove. The cooperation between the pin insertion hole and the spring pin achieves the limiting of the rotating pressure plate. At this time, the pressure plate on the rotating pressure plate presses down on the battery pack, compressing the battery pack and preventing the battery pack from bouncing up and down during transportation. When the battery pack needs to be released, the spring pin is pulled out, so that the spring pin disengages from the pin insertion hole. The rotating pressure plate is automatically returned to its original position by the action of the right-hand torsion spring. Then, the screws on the mounting hole are removed to complete the disassembly of the rotating pressure rod structure.

[0006] Preferably, the right-hand torsion spring is placed inside the bushing hole and is sleeved on the bushing.

[0007] Preferably, the bushing has a hollow structure with a bolt inserted inside. One end of the bolt passes through the bushing and is threaded to a lock nut. The rotating pressure plate is positioned between the lock nut and the pressure rod base. The bolt and lock nut ensure that the rotating pressure plate is stably positioned between the lock nut and the pressure rod base, thus achieving stable rotation.

[0008] Preferably, the rotating pressure plate has a pin hole and a bushing hole. The pin hole corresponds to the spring pin, and the plug end of the spring pin is inserted into the pin hole. The bushing hole corresponds to the bushing, and the bushing passes through the bushing hole. The plug end of the spring pin is inserted into the pin hole, which achieves the rotation limit of the rotating pressure plate.

[0009] Preferably, the mounting base has mounting holes at all four corners. These mounting holes allow the mounting base to be installed at the desired location.

[0010] Preferably, the rotating pressure plate has a pin guide groove in the middle, and the pin guide groove is correspondingly set with the spring pin. The pin guide groove has an inclined surface with an inclination angle of 45°. The 45° inclination angle of the inclined surface facilitates the insertion of the spring pin into the pin hole, thus playing an auxiliary role in the insertion.

[0011] Preferably, one end of the spring pin passes through the pin fixing hole, and the length of the pin passing through the pin fixing hole is 3mm-9mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the cooperation between a spring pin and a pin insertion hole to effectively limit the rotation of the pressure plate, ensuring it firmly presses against the battery pack and preventing it from bouncing during transport, thus guaranteeing the battery pack's safety. The right-hand torsion spring allows the pressure plate to automatically return to its original position when the spring pin disengages from the pin insertion hole, facilitating operation. A bolt inserted into the bushing, along with a locking nut, stably positions the pressure plate between the locking nut and the pressure rod base, ensuring the stability of the pressure plate's rotation. The pin guide groove on the pressure plate, with its 45° inclined surface, facilitates the insertion of the spring pin into the pin insertion hole, providing auxiliary guidance. The mounting holes on the mounting base allow for easy installation of this structure on a circulating material rack, simplifying installation and disassembly. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-6 This utility model provides a rotating pressure rod structure, including a rotating pressure plate 2, a pressure rod base 4, and a mounting base 6. The middle part of the top of the mounting base 6 is fixedly welded to the bottom end of the pressure rod base 4. The pressure rod base 4 has a pin fixing hole 15 and a bushing through hole 14 from top to bottom. A bushing 16 is inserted into the bushing through hole 14, and one end of the bushing 16 passes through the bushing through hole 14 and is sleeved on the rotating pressure plate 2. The other end of the bushing 16 is welded to the opening in the middle of the torsion spring fixing seat 7, and the torsion spring fixing seat 7 is welded to the pressure rod base 4. One end of the right-hand torsion spring 3 is fixedly connected to the torsion spring fixing seat 7, and the other end of the right-hand torsion spring 3 is fixedly connected to the rotating pressure plate 2. A spring pin 5 is fixedly welded inside the pin fixing hole 15. A pressure plate 10 is installed on the rotating pressure plate 2, and a rubber sleeve 1 is glued to the outside of the pressure plate 10. The spring pin 5 consists of an outer tube, a spring, and a pin. Both the spring and the pin are located inside the outer tube. The spring is sleeved on the pin, with one end of the spring fixed to the inner wall of the outer tube and the other end of the spring fixed to the surface of the pin. The outer tube is fixedly welded to the pin fixing hole 15 to avoid affecting the insertion and removal function of the spring pin 5.

[0023] The right-hand torsion spring 3 is placed inside the bushing through hole 14, and the right-hand torsion spring 3 is sleeved on the bushing 16.

[0024] Specifically, by setting the right-hand torsion spring 3, the rotating pressure plate 2 can automatically return to its original position after disengaging from the pin insertion hole 12.

[0025] The bushing 16 is a hollow structure, and a bolt 17 is inserted inside. One end of the bolt 17 passes through the bushing 16 and is threaded to a lock nut 8. The rotating pressure plate 2 is placed between the lock nut 8 and the pressure rod base 4.

[0026] Specifically, the rotating pressure plate 2 is stably limited by the cooperation of bolt 17 and anti-loosening nut 8, ensuring its stability during rotation.

[0027] The rotating pressure plate 2 has a pin insertion hole 12 and a bushing insertion hole 13. The pin insertion hole 12 is correspondingly set with the spring pin 5, and the plug end of the spring pin 5 is inserted into the pin insertion hole 12. The bushing insertion hole 13 is correspondingly set with the bushing 16, and the bushing 16 passes through the bushing insertion hole 13.

[0028] Specifically, the spring pin 5 is inserted into the pin insertion hole 12 to limit the rotation of the rotating pressure plate 2, and the bushing 16 passes through the bushing insertion hole 13 to provide support for the rotation of the rotating pressure plate 2.

[0029] Mounting holes 9 are provided at all four corners of the mounting base 6.

[0030] Specifically, the mounting base 6 can be installed on the circulating material rack using screws through the mounting hole 9, making it easy to install and remove.

[0031] The rotating pressure plate 2 has a pin guide groove 11 in the middle, and the pin guide groove 11 is correspondingly set with the spring pin 5. The pin guide groove 11 has an inclined surface, and the inclined surface has an inclination angle of 45°.

[0032] Specifically, the 45° inclined surface design allows the spring pin 5 to be more smoothly inserted into the pin insertion hole 12 when rotating the rotating pressure plate 2.

[0033] One end of the spring pin 5 passes through the pin fixing hole 15, and the length of the pin passing through the pin fixing hole 15 is 3mm-9mm.

[0034] Specifically, this length setting ensures that the spring pin 5 can be effectively inserted into the pin socket 12 for limiting, while also preventing it from being too long and affecting the operation of other components.

[0035] Working principle: When the battery pack needs to be compressed, the mounting base 6 is installed on the circulating material rack through the mounting hole 9 and screws. Then, the rotating pressure plate 2 is rotated so that the spring pin 5 enters the pin insertion hole 12 through the pin guide groove 11. The cooperation between the pin insertion hole 12 and the spring pin 5 realizes the limiting of the rotating pressure plate 2. At this time, the pressure plate 10 on the rotating pressure plate 2 presses down on the battery pack and compresses the battery pack to prevent the battery pack from bouncing up and down during transportation. When the battery pack needs to be released, the spring pin 5 is pulled out so that the spring pin 5 disengages from the pin insertion hole 12. The rotating pressure plate 2 is automatically returned to its original position by the action of the right-hand torsion spring 3. Then, the screws on the mounting hole 9 are removed to complete the disassembly of the rotating pressure rod structure.
