Description

Technical Field

[0001] This utility model relates to the field of lithium battery frame technology, specifically an insulating frame for lithium battery mounting. Background Technology

[0002] A lithium-ion battery is a type of rechargeable battery that primarily works by the movement of lithium ions between the positive and negative electrodes. A lithium-ion battery is a modular assembly composed of many individual battery cells. The assembly is encapsulated in a structure that provides support, rigidity, electrical insulation, and chemical resistance for the entire assembly structure. A frame is used to limit and protect the multiple cells.

[0003] Most existing lithium-ion battery frames are made of plastic, and their production is largely customized according to the number of batteries required for lithium-ion battery installation. This means that the number of batteries that can be installed in the battery frame cannot be changed, resulting in poor versatility. Based on this, an insulating frame for lithium battery installation is provided. Utility Model Content

[0004] The purpose of this utility model is to provide an insulating frame for installing lithium batteries in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating frame for lithium battery installation, comprising a U-shaped frame, wherein two vertically distributed U-shaped frames are joined together to form a space for placing a single battery, horizontal splicing components are provided on both sides of the U-shaped frame, and two horizontally distributed adjacent U-shaped frames are spliced ​​together by the horizontal splicing components, and a vertical snap-fit ​​component is provided on the top of the U-shaped frame, wherein the two vertically distributed U-shaped frames are snap-fitted and fixed by the vertical snap-fit ​​component;

[0006] The horizontal splicing assembly includes a C-type sleeve, a snap-fit ​​post, and a bottom sealing block;

[0007] The C-shaped sleeves and locking posts are symmetrically distributed on both sides of the U-shaped frame. There are two C-shaped sleeves and two locking posts, which are respectively distributed at both ends of the side of the U-shaped frame.

There are two first L-shaped slots, which are symmetrically formed on the top two sides of the U-shaped frame. The first 7-shaped buckles and the first L-shaped slots are symmetrically distributed with the horizontal axis of the U-shaped frame as the center.

[0012] The second 7-shaped buckle is fixed to the middle of one end of the top of the U-shaped frame, and the second L-shaped slot is formed in the middle of the other end of the top of the U-shaped frame;

[0013] When two U-shaped frames are vertically joined, they are first placed vertically symmetrically, and then rotated horizontally by 180 degrees.

[0016] As a further improvement of this utility model, the U-shaped frame, horizontal splicing component, vertical snap-fit ​​component, electrical connection slot, and heat dissipation slot are integrally formed by injection molding.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 In this embodiment of the utility model, an insulating frame for installing lithium batteries includes a U-shaped frame 1. The space formed by two vertically distributed U-shaped frames 1 interlocking with each other is used to provide a placement space for a single battery. Horizontal splicing components 2 are provided on both sides of the U-shaped frame 1. Two horizontally distributed adjacent U-shaped frames 1 are spliced ​​together by the horizontal splicing components 2. A vertical snap-fit ​​component 3 is provided on the top of the U-shaped frame 1. The two vertically distributed U-shaped frames 1 are snapped and fixed by the vertical snap-fit ​​component 3.

[0025] The horizontal splicing component 2 includes a C-type sleeve 201, a snap-fit ​​post 202, and a bottom sealing block 203;

[0026] C-type sleeves 201 and snap-fit ​​posts 202 are symmetrically distributed on both sides of the U-shaped frame 1. There are two C-type sleeves 201 and snap-fit ​​posts 202, and the two C-type sleeves 201 and snap-fit ​​posts 202 are respectively distributed at both ends of the side of the U-shaped frame 1.

[0027] The bottom horizontal height of the C-type sleeve 201 is higher than the bottom horizontal height of the U-shaped frame 1. The bottom sealing block 203 is fixed to the bottom of the C-type sleeve 201, and the bottom of the bottom sealing block 203 is flush with the bottom of the U-shaped frame 1, while the top of the bottom sealing block 203 is flush with the bottom of the C-type sleeve 201.

[0028] When two U-shaped frames 1 are horizontally spliced, the connection between the two U-shaped frames 1 is achieved by snapping the snap-fit ​​post 202 into the inside of the C-shaped sleeve 201. The arbitrary splicing of the U-shaped frames 1 can be used to achieve different numbers of battery assembly operations.

[0029] The vertical snap-fit ​​component 3 includes a first 7-shaped snap fastener 301, a first L-shaped slot 302, a second 7-shaped snap fastener 303, and a second L-shaped slot 304;

[0030] Two first 7-shaped buckles 301 are provided, and the two first 7-shaped buckles 301 are symmetrically fixed on the top two sides of the U-shaped frame 1. Two first L-shaped slots 302 are provided, and the two first L-shaped slots 302 are symmetrically formed on the top two sides of the U-shaped frame 1. The first 7-shaped buckles 301 and the first L-shaped slots 302 are symmetrically distributed with the transverse axis of the U-shaped frame 1 as the center.

[0031] The second 7-shaped buckle 303 is fixed to the middle of one top end of the U-shaped frame 1, and the second L-shaped slot 304 is formed in the middle of the other top end of the U-shaped frame 1;

[0032] When two U-shaped frames 1 are vertically spliced, the two U-shaped frames 1 are first vertically symmetrical, and then rotated horizontally by 180 degrees. The two vertically spliced ​​U-shaped frames 1 are fixed by engaging the second 7-shaped buckle 303 with the second L-shaped slot 304 and engaging the first 7-shaped buckle 301 with the first L-shaped slot 302.

[0033] In this embodiment, the operation steps for assembling a lithium battery module from multiple batteries are as follows:

[0034] First, select the appropriate number of U-shaped frames 1 according to the number of batteries to be assembled (the number of batteries is n, and the number of U-shaped frames 1 is 2n). Then, divide the U-shaped frames 1 into two groups and splice them horizontally. When splicing two adjacent U-shaped frames 1, simply insert the snap-fit ​​post 202 on one U-shaped frame 1 into the inside of the C-shaped sleeve 201 on the other U-shaped frame 1 from top to bottom. The bottom sealing block 203 can provide support for the bottom of the snap-fit ​​post 202. After that, install the above steps and connect the other U-shaped frames 1 with the previous U-shaped frame 1 in sequence (it should be noted that at this time, the first 7-shaped buckle 301 and the second 7-shaped buckle 303 on the horizontally distributed U-shaped frames 1 are aligned in the horizontal direction).

[0035] After completing the horizontal splicing of the two sets of U-shaped frames 1, first take one set of U-shaped frames 1 with its opening facing upwards, and then put the multiple batteries to be assembled into each U-shaped frame 1. Then take another set of U-shaped frames 1 with its opening facing downwards, and rotate it horizontally by 180 degrees relative to the lower U-shaped frame 1, so that the first 7-shaped buckle 301 and the second 7-shaped buckle 303 on the upper U-shaped frame 1 are aligned with the first L-shaped slot 302 and the second L-shaped slot 303 on the lower U-shaped frame 1, respectively.

[0036] Then, the upper U-shaped frame 1 is fitted onto the outer top of the battery. As the upper U-shaped frame 1 and the lower U-shaped frame 1 approach and fit together, the first 7-shaped buckle 301 and the second 7-shaped buckle 303 will respectively snap into the first L-shaped slot 302 and the second L-shaped slot 303 (it should be noted that the first 7-shaped buckle 301 and the second 7-shaped buckle 303 have a certain deformation and restoring elasticity), thereby fixing the upper and lower U-shaped frames 1. At this time, the battery is limited to be fitted between the two upper and lower U-shaped frames 1, thus achieving the limitation and protection of the battery.

[0037] By combining the above components, different numbers of batteries can be assembled. Compared with the traditional fixed-quantity structure, it is more flexible, more versatile, and has a wider range of applications.

[0038] Please refer to this carefully. Figures 1-3 The bottom of the U-shaped frame 1 is provided with an electrical connection slot 4, and the two sides of the U-shaped frame 1 are provided with heat dissipation slots 5. The first 7-shaped buckle 301 and the first L-shaped slot 302 are distributed at both ends of the heat dissipation slots 5.

[0039] The U-shaped frame 1, horizontal splicing component 2, vertical snap-fit ​​component 3, power connection slot 4, heat dissipation slot 5 are integrally formed by injection molding.

[0040] In this embodiment: the setting of the power connection slot 4 facilitates the later electrode connection between batteries, and the heat dissipation slot 5 enables better heat dissipation on both sides of the battery.

[0041] In addition, the U-frame 1, which is integrally molded by injection molding, has a simple overall production process with fewer steps. When assembling later, the U-frame 1 does not need to consider the top and bottom, and can be freely spliced ​​to different lengths. It is convenient to assemble, highly flexible, and has a good market prospect.

[0042] Please refer to this carefully. Figures 1-3 The snap-fit ​​post 202 and the bottom sealing block 203 have through holes formed in the middle. The two U-shaped frames 1 are horizontally spliced ​​and reinforced by external screws passing through the bottom sealing block 203, snap-fit ​​post 202 and through holes.

[0043] In this embodiment: After the assembly of the U-frame 1 is completed, if it is necessary to strengthen the connection, a screw can be threaded through the bottom sealing block 203 and connected to the snap-fit ​​post 202 to increase the horizontal connection force between two adjacent U-frames 1. Alternatively, an extended screw can be threaded through the upper and lower snap-fit ​​posts 202 and connected to them to increase the connection force between the upper and lower U-frames 1.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
