Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a compact cylindrical lithium battery array packaging bracket. Background Technology

[0002] Cylindrical lithium battery packaging brackets are structural components used to fix and support multiple cylindrical lithium batteries. They are typically made of materials with high temperature resistance and good insulation properties. Physical isolation ensures insulation between cells, avoiding the risk of short circuits; maintaining reasonable spacing between cells optimizes heat dissipation and prevents localized overheating; and the overall structural design enhances the mechanical strength of the module, maintaining structural stability under vibration or impact environments, preventing cell displacement or connector detachment, thereby improving the safety and reliability of the lithium battery pack.

[0003] Existing technologies for cylindrical lithium battery array packaging present numerous problems. On the one hand, the lack of precise positioning during assembly makes lithium batteries prone to shifting and shaking, resulting in uneven arrangement, affecting subsequent packaging and usage stability, and reducing the reliability and safety of the battery array. On the other hand, traditional packaging structures use bolts or clips for fixing, and disassembly and maintenance often require tools, making the process cumbersome, time-consuming, and labor-intensive, thus reducing the efficiency of maintaining and replacing lithium batteries. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a compact cylindrical lithium battery array packaging bracket, which improves the stability and accuracy of lithium battery assembly, and enables automatic insertion and packaging without tools; it can quickly disassemble and assemble the top frame, which is convenient for maintenance and replacement, and improves the flexibility and convenience of use.

[0005] The technical solution adopted by this utility model is as follows: It includes a positioning frame, with the limiting rings evenly fixed on the top, and the lithium battery body located within the limiting rings; a vertical connecting seat, fixed to the top of the positioning frame and distributed at the four corners of the positioning frame; a detachable top frame, fixedly connected to the vertical connecting seat via the elastic self-locking pin assembly, used to limit the lithium battery body from above; and a rotary pushing assembly installed at the bottom of the detachable top frame, one end of which is located on one side of the elastic self-locking pin assembly, used to push and control the elastic self-locking pin assembly.

[0007] Preferably, in order to limit the pin head by means of the first limiting slide rod, the bottom end of the detachable top frame is fixedly installed with the first connecting seat, the inner wall of the first connecting seat is fixedly installed with the first limiting slide rod, and the pin head is slidably sleeved on the first limiting slide rod.

[0008] Preferably, in order to ensure that the pin head is tightly against the inner wall of the vertical connecting seat by means of the clamping spring, thereby fixing the positioning protrusion into the limiting slot, the pin head is elastically connected to the inner wall of the first connecting seat by means of the clamping spring.

[0009] Preferably, in order to control the rotation of the micro threaded rod so that the push threaded block can drive the extension push plate to move, thereby pushing the pin head and facilitating the positioning protrusion to disengage from the limiting slot, the screw-type push assembly includes a second connecting seat fixed to the bottom end of the detachable top frame. The micro threaded rod is rotatably mounted on the inner wall of the first connecting seat. The push threaded block is threaded onto the micro threaded rod. The extension push plate is fixed on the side wall of the push threaded block, and one end of the extension push plate is located on one side of the pin head.

[0010] Preferably, in order to limit the push threaded block by means of the second limiting slide rod, one end of the push threaded block is slidably sleeved on the second limiting slide rod installed on the inner wall of the second connecting seat.

[0011] Preferably, in order to enable the micro threaded rod to rotate via the screwing head, the screwing head is fixedly mounted on one end of the micro threaded rod.

[0012] Preferably, in order to improve the stability of the lithium battery body packaging by means of the limiting strip, the vertical connecting seats located at the four corners of the positioning frame are connected by the limiting strip, and the limiting strip is used to limit the lithium battery body from the side.

[0013] The beneficial effects of this utility model are: the limiting ring enables the lithium battery body to be perpendicularly aligned with the detachable top frame during assembly, resulting in higher stability and assembly precision; the flexible self-pin assembly enables automatic insertion and sealing of the detachable top frame without tools; the screw-type push assembly allows for quick disassembly and installation of the top frame, facilitating maintenance and replacement of the lithium battery body, and improving the flexibility and convenience of use.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5As shown, this embodiment provides a compact cylindrical lithium battery array packaging bracket, including a positioning frame 1 with uniformly fixed limiting rings 2 on the top. The lithium battery body 3 is located in the limiting rings 2. During assembly, it is placed stably on a suitable working plane. The uniformly distributed limiting rings 2 on the top provide precise placement positions for the lithium battery body 3. The lithium battery body 3 can be placed one by one into its corresponding limiting ring 2, preventing displacement or shaking in the array and ensuring that multiple lithium battery bodies 3 are arranged neatly and orderly. This provides a stable foundation structure for subsequent packaging and use, improving the reliability and safety of the entire battery array. Vertical connecting seats 4 are fixed to the top of the positioning frame 1 and distributed at the four corners of the positioning frame 1. The vertical connecting seats 4 at the four corners provide stable connection points for the detachable top frame 5, allowing the detachable top frame 5 to be accurately installed above the positioning frame 1. This also enhances the structural strength of the entire packaging bracket, enabling it to withstand certain external impacts and protecting the internal lithium battery body 3. The detachable top frame 5 is designed to be removable. The top frame 5 is fixedly connected to the vertical connecting seat 4 via the flexible self-locking pin assembly 6, which is used to limit the lithium battery body 3 from above. During installation, the flexible self-locking pin assembly 6 is aligned with the vertical connecting seat 4 and inserted to achieve automatic connection without tools. A screw-type pushing assembly 7 is installed at the bottom of the detachable top frame 5. One end of the screw-type pushing assembly 7 is located on one side of the flexible self-locking pin assembly 6, which is used to push and control the flexible self-locking pin assembly 6. When it is necessary to disassemble the detachable top frame 5, the screw-type pushing assembly 7 is screwed. Its pushing end applies force to the elastic self-inserting pin assembly 6, causing the elastic self-inserting pin assembly 6 to separate from the vertical connecting seat 4, realizing the quick disassembly and installation of the detachable top frame 5, and improving the efficiency of maintenance and replacement of the lithium battery body 3; the vertical connecting seats 4 located at the four corners of the positioning frame 1 are connected by limiting strips 8. The limiting strips 8 are used to limit the lithium battery body 3 from the side. When in use, the lithium battery body 3 is further limited from the side, enhancing the stability of the lithium battery body 3 in the horizontal direction.

[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 4As shown, the elastic self-locking pin assembly 6 includes a pin head 601 vertically corresponding to the vertical connecting seat 4. One end of the pin head 601 is provided with a positioning protrusion 602, which is inserted into a limiting slot on the vertical connecting seat 4. The bottom end of the detachable top frame 5 is fixedly installed with a first connecting seat 603, and a first limiting slide rod 604 is fixedly installed on the inner wall of the first connecting seat 603. The pin head 601 is slidably sleeved on the first limiting slide rod 604. The pin head 601 is elastically connected to the inner wall of the first connecting seat 603 through a clamping spring 605. When installing the detachable top frame 5, the pin head 601 is aligned with the vertical connecting seat 4, and the detachable top frame 5 is pressed down so that the positioning protrusion 602 corresponds to the limiting slot. Under the action of the clamping spring 605, the pin head 601 slides along the first limiting slide rod 604. At this time, the positioning protrusion 602 is inserted into the limiting slot, so that the positioning protrusion 602 is firmly fixed in the slot. During disassembly, overcome the elastic force to disengage the positioning protrusion 602 from the limiting slot, and pull the pin head 601 to remove the detachable top frame 5.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the rotary push assembly 7 includes a second connecting seat 701 fixed to the bottom of the detachable top frame 5. A miniature threaded rod 702 is rotatably mounted on the inner wall of the first connecting seat 603. A push threaded block 703 is threaded onto the miniature threaded rod 702. An extension push plate 704 is fixed on the side wall of the push threaded block 703. One end of the extension push plate 704 is located on one side of the pin head 601. One end of the push threaded block 703 is slidably sleeved on a second limiting slide bar 705 installed on the inner wall of the second connecting seat 701. A screwing head 706 is fixedly mounted on one end of the miniature threaded rod 702. When the detachable top frame 5 needs to be disassembled, the screwing head 706 is rotated, causing the miniature threaded rod 702 to rotate. Since the push threaded block 703 cannot rotate due to the restriction of the second limiting slide bar 705, it will move along the miniature threaded rod 702, thereby causing the extension push plate 704 to push the pin head 601, causing the positioning protrusion 602 to disengage from the limiting slot. Conversely, rotating the screw head 706 in the opposite direction causes the extended push plate 704 to move back, releasing the push on the pin head 601.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
