Description

Technical Field

[0001] This utility model belongs to the field of lithium battery processing technology, and in particular relates to a clamping device for lithium battery energy storage devices. Background Technology

[0002] A clamping device for lithium battery energy storage devices, disclosed in related technology (publication number CN219235087U), uses a cylinder to push a push plate up and down, thereby rotating an L-shaped plate. This causes the L-shaped slider to slide inside a moving groove, and the moving clamping block at the top of the L-shaped slider moves on the clamping platform to loosen the lithium battery. Simultaneously, multiple sets of insertion holes at the top of the clamping platform and the top of the L-shaped slider allow the moving clamping block and the limiting block at different positions to be inserted into these holes. This allows for adjustment of the clamping space according to different sizes of lithium batteries, solving the problem that existing technologies using clamping plates with fixed shapes can only clamp lithium batteries of a fixed size, failing to meet the need to clamp lithium batteries of different sizes.

[0003] However, the device requires a hydraulic cylinder to drive the clamping and fixing process, which not only increases the cost, but also requires the replacement of hydraulic oil and repair of leaks, making it unsuitable for long-term use. Furthermore, the hydraulic cylinder is greatly affected by environmental factors such as temperature, dust, and humidity, making it difficult to maintain stable clamping. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for lithium battery energy storage devices. By setting a locking part, the problem of the device requiring a hydraulic cylinder to drive clamping and fixing during use is solved. This not only increases the cost, but also requires the replacement of hydraulic oil and repair of leaks, making it inconvenient for long-term use. Furthermore, the hydraulic cylinder is greatly affected by environmental factors such as temperature, dust, and humidity, making it difficult to maintain clamping stability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a clamping device for a lithium battery energy storage device, comprising a rectangular housing, and further comprising: a support portion disposed on the rectangular housing; a locking portion mounted on the rectangular housing; a clamping portion disposed above the locking portion; the locking portion comprising a latching assembly mounted on the rear side of the rectangular housing; and a transmission assembly disposed on the rectangular housing; the latching assembly comprising a first ring disposed at the rear of the rectangular housing, and a second ring disposed at the front side of the first ring. The front side of the first ring has several slots, and the rear side of the second ring is fixedly connected to several blocks. The blocks extend into the slots, and the outer walls of the blocks contact the slots. The rear side of the first ring has an elastic element, and the rectangular shell has a support element. The front side of the second ring is rotatably connected to the rear side of the rectangular shell. The buckle assembly engages with the slots and blocks of the first and second rings, and works with the elastic element to lock and unlock the rotating shaft, preventing loosening after clamping and ensuring stable clamping.

[0007] Furthermore, the support portion includes a partition fixedly connected to the inner wall of the rectangular housing, and two support legs fixedly connected to the bottom of the rectangular housing; wherein the partition is located above the two support legs, the clamping portion includes an engagement assembly installed inside the rectangular housing; and a clamping assembly disposed on the rectangular housing.

[0008] Furthermore, the transmission assembly includes a rotating shaft rotatably connected to the rear side of the rectangular housing. A bevel gear is fixedly connected to the outer wall of the rotating shaft rotatably. A rotating shaft rotatably passes through the partition and is rotatably connected to the partition. A bevel gear is fixedly connected to the outer wall of the rotating shaft rotatably. The bevel gear rotatably meshes with the bevel gear rotatably. The rotating shaft rotatably passes through and is fixedly connected to the circular ring rotatably. The transmission assembly transmits the rotational motion of the rotating shaft rotatably to the rotating shaft rotatably via the bevel gear transmission, providing power transmission for the action of the clamping part and realizing the conversion of manual operation into clamping force.

[0009] Furthermore, the meshing assembly includes a gear fixedly connected to the outer wall of the second rotating shaft, and several L-shaped support blocks are fixedly connected to the top of the partition. Two slotted racks are slidably connected to the several L-shaped support blocks. Both slotted racks mesh with the gear. The meshing assembly converts the rotational motion of the second rotating shaft into the linear motion of the slotted racks through the meshing of the gear and the slotted racks, thereby driving the clamping assembly to adjust the clamping space.

[0010] Furthermore, the clamping assembly includes rectangular connecting blocks fixedly connected to the tops of two slotted racks respectively. The top of the rectangular housing has two guide grooves, the inner walls of which are slidably connected to the two rectangular connecting blocks respectively. The tops of the two rectangular connecting blocks are fixedly connected to clamping plates, and buffer pads are fixedly connected to the sides of the two clamping plates that are close to each other. A guide is provided on the top of the rectangular housing. The two rectangular connecting blocks are arranged in a circumferential array. The clamping assembly uses the clamping plates and buffer pads to directly contact and fix the lithium battery energy storage device. The guide structure ensures stable clamping while buffering and protecting the battery, adapting to the clamping requirements of batteries of different specifications.

[0011] Furthermore, the elastic element includes a spring fixedly connected to the rear side of the ring; wherein the spring is in a compressed state, the support element includes an L-shaped support block fixedly connected to the rear side of the rectangular housing, a slide cylinder is fixedly connected to the front inner wall of the L-shaped support block, the rotating shaft rotatably passes through the L-shaped support block, the front inner wall of the L-shaped support block is fixedly connected to the rear side of the spring, and the slide cylinder is rotatably connected to the rotating shaft; wherein the slide cylinder slides through the ring, and the guide element includes two guide grooves two formed on the top of the rectangular housing; wherein the bottoms of the two clamping plates slide into the two guide grooves two respectively.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting a locking part, the buckle assembly and the transmission assembly cooperate to fix and unlock the clamping action. In the buckle assembly, ring one and ring two, through the engagement of the slot and the block, combined with the pre-tightening force of the elastic element, can stably restrict the rotation of the shaft, prevent loosening after clamping, and ensure the reliability of the clamping state. The transmission assembly converts the rotation operation into the power transmission of the clamping part, so that the force of manual operation can be effectively transmitted, ensuring that the clamping process is controllable. The clamping and fixing can be completed without an additional power source, which not only reduces the cost, but also reduces the impact of environmental factors such as temperature, dust, and humidity on the device, thereby maintaining the stability of clamping and increasing the practicality of the device.

[0014] 2. By setting up a clamping part, the engagement component and the clamping component work together to achieve stable clamping of the lithium battery energy storage device. In the engagement component, the meshing transmission of the gear and the slotted rack converts the rotational motion into linear motion, causing the clamping plate of the clamping component to move closer or further away synchronously. The clamping plate of the clamping component is equipped with a buffer pad, which can not only ensure the smoothness of movement through the guide groove, but also play a buffering protection role during clamping to avoid damage to the battery shell. At the same time, it ensures that the battery remains stable during installation, maintenance and other processes, and ensures the safety and structural stability of the energy storage system.
