Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a short-circuit-proof lithium battery assembly frame. Background Art

[0002] When lithium batteries are installed and used, they are generally directly installed on the corresponding battery box or battery assembly rack. The lithium battery is provided with positive and negative electrodes, which are usually connected to external wires for use. The external wires are generally provided with insulating sleeves. However, the copper wires or aluminum wires at the connection parts between the wires and the positive and negative electrodes on the lithium battery are generally directly exposed to the outside, so that the external insulating sleeves will not hinder the transmission of electricity. Conventional lithium battery assembly racks lack corresponding anti-short circuit components, and cannot separate the copper wires exposed to the outside of the two wires;

[0003] Chinese patent CN202320827101.0 in the prior art discloses an anti-short circuit lithium battery assembly rack, including a lithium battery placement rack, a placement chamber is arranged inside the lithium battery placement rack, a wiring hole connected to the outside is arranged on the top wall of the placement chamber, an insulating partition is fixedly installed on the top surface of the lithium battery placement rack, the insulating partition is located in the middle position of the wiring hole, and is used to separate two wires to prevent short circuit, and a rear side limit plate is also fixedly installed on the top surface of the lithium battery placement rack, and two mutually symmetrical insulating sleeve assemblies are arranged on the rear side limit plate, and the insulating sleeve assembly includes an insulating bellows fixedly installed on the rear side limit plate, and a bending sleeve bent toward one side of the wiring hole is fixedly installed on the rear end of the insulating bellows;

[0004] The above-mentioned prior art can separate the wires connected to the positive and negative electrodes on the battery. In addition, by setting the insulating sleeve assembly, the exposed copper wire can be further wrapped inside, which plays an insulating protection effect and reduces the occurrence of short circuits, thus solving the technical problem of the lack of corresponding anti-short circuit components on the conventional lithium battery assembly rack.

[0005] Based on the search of the above patents and the implementation in combination with the prior art, it is found that when the above component rack is used, the protective structure of the insulating sleeve component is used to pass the copper wire. Due to the fixed structural design of the kit, the copper wire can only pass through in one direction and the passing direction of the wire body cannot be changed. Therefore, it cannot be applied to more application environment requirements and has certain usage limitations. For this reason, the utility model proposes an optimized anti-short circuit lithium battery component rack. Utility Model Content

[0026] See also Figure 1-4 The utility model provides an embodiment: an anti-short circuit lithium battery assembly rack, including an assembly rack 1, a lithium battery body 2 is fixedly installed inside the assembly rack 1, and in specific implementation, the lithium battery body 2 and the four corners of the assembly rack 1 can be filled with protective pads, and the pads are made of silicone pads, so that the four corners of the lithium battery 2 can be protected from collision. Through holes are opened on both sides of the upper surface of the assembly rack 1 and located on the positive and negative electrodes of the lithium battery body 2, and upper connecting sleeves 3 are sleeved on the outside of the two through holes, and the two upper connecting sleeves 3 are both insulating sleeves;

[0027] Among them, the upper connecting sleeve 3 is fixedly installed on the upper surface of the component frame 1, and an internal threaded portion 4 is arranged inside the upper connecting sleeve 3. A protective cover 5 is arranged above the two upper connecting sleeves 3. Heat dissipation grooves 6 are opened on the outer walls on both sides of the component frame 1. The heat dissipation grooves 6 can ensure the normal heat dissipation of the internal lithium battery body 2. An insulating partition 7 is fixedly installed between the two upper connecting sleeves 3 and located on the upper surface of the component frame 1.

[0028] In this embodiment, the protection kit 5 includes a lower threaded barrel 501, and the lower threaded barrel 501 and the upper connecting sleeve 3 are of an adaptable structural design, so that the protection kit 5 of the utility model can be installed in the upper connecting sleeve 3 by threading through the lower threaded barrel 501, and the protection kit 5 can be quickly installed and disassembled by threaded connection, and can be conveniently disassembled for regular inspection and maintenance, thereby improving the overall protection effect of the component frame 1, having a convenient maintenance effect, and having good performance;

[0029] A primary insulating sleeve 502 is fixedly mounted on the upper surface of the top of the lower threaded cylinder 501;

[0030] Furthermore, a bellows 503 is fixedly connected to the upper surface of the primary insulating sleeve 502, and a secondary insulating sleeve 504 is fixedly installed on the top of the bellows 503. The size and structure of the primary insulating sleeve 502 and the secondary insulating sleeve 504 are the same, and the bellows 503 is made of insulating material;

[0031] The primary insulating sleeve 502, the corrugated tube 503 and the secondary insulating sleeve 504 are provided to form an insulating protective sleeve assembly for the external copper wire, so that the wires connected to the positive and negative electrodes on the battery can be separated by the above structure, which can effectively prevent the copper wires from being directly exposed to the outside, and achieve a good insulation protection effect, and prevent the positive and negative electrode wires from being entangled or contacted with each other to cause a short circuit, thereby solving the technical problem of the lack of corresponding anti-short circuit components on the conventional lithium battery assembly rack;

[0032] In addition, the primary insulating sleeve 502 and the secondary insulating sleeve 504 of the utility model are flexibly connected via a bellows 503. The overall posture of the insulating protective sleeve assembly can be changed by bending the bellows 503, so that the outlet port of the secondary insulating sleeve 504 can be adjusted in direction through the swing of the bellows 503, so that it can be oriented to different angles and positions. In actual use, the bellows 503 can be swung 360° to adjust the posture, so that the direction and angle of the copper wire passing through can be dynamically adjustable, the angle adjustment range is large, and the scope of application is wide, so that the component rack 1 of the utility model can be applied to different threading angle requirements, so that it can be applied to more application environments, and effectively reduce the limitations of use.

[0033] Among them, in order to facilitate the wire management work of threading the copper wire, an inner threading plate 505 is fixedly installed inside the upper part of the secondary insulating sleeve 504, and a plurality of evenly distributed threading holes 506 are opened on the inner threading plate 505. When threading, the copper wire can be passed through the threading holes 506 of the inner threading plate 505, so that the hole position of the copper wire body can be limited, which has a better wire management and threading effect and improves the neatness of the wire body.

[0034] Working principle: When the utility model is in use, an upper connecting sleeve 3 is arranged on the component frame 1, and the upper connecting sleeve 3 can be threadedly connected with the lower threaded cylinder 501 of the protection kit 5, so that the overall installation of the protection kit 5 can be completed, and the protection kit 5 can be quickly installed and disassembled by threaded connection, and regular disassembly, inspection and maintenance can be conveniently performed, thereby improving the overall protection effect of the component frame 1, having a convenient maintenance effect, and good use performance;

[0035] Then, the connecting wires of the lithium battery body 2 are passed through the upper connecting sleeve 3 and the protective sleeve 5, thereby completing the wiring work of the lithium battery body 2. The utility model forms an insulating protective sleeve assembly for the external copper wire by setting the primary insulating sleeve 502, the corrugated tube 503 and the secondary insulating sleeve 504. The wires connected to the positive and negative electrodes on the battery can be separated by the above structure, which can effectively prevent the copper wires from being directly exposed to the outside, play a good insulation protection effect, and prevent the positive and negative electrode wires from being entangled or contacting each other to cause a short circuit, which solves the technical problem of the lack of corresponding anti-short circuit components on the conventional lithium battery assembly rack, and has a certain anti-short circuit protection effect;

[0036] In addition, the primary insulating sleeve 502 and the secondary insulating sleeve 504 of the utility model are flexibly connected through the bellows 503. By bending the bellows 503, the overall posture of the insulating protective sleeve assembly can be changed, so that its shape can be changed. Specifically, when in use, it can be in the vertical shape shown in the drawings, or in the L-shaped shape of the arc-shaped connection, and can also be in the U-shaped shape.

[0037] In this way, the direction of the outlet port of the secondary insulating sleeve 504 can be adjusted by the swing of the bellows 503, so that it can be oriented to different angles and positions. In actual use, the bellows 503 can be swung 360° to adjust the posture, so that the direction and angle of the copper wire passing out can be dynamically adjustable. The angle adjustment range is large and the application range is wide, so that the component rack 1 of the utility model can be applied to different threading angle requirements, so that it can be applied to more application environments, effectively reducing the limitations of use.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
