DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1-Figure 4 as well as Figure 6 As shown, a battery placement rack for temperature resistance testing provided by an embodiment of the utility model includes a base 1, characterized in that a plurality of battery placement components 3 are detachably connected to the surface of the base 1;

[0027] The battery placement assembly 3 includes a first placement plate 301 and a second placement plate 302, and the first placement plate 301 and the second placement plate 302 are both detachably connected to the base 1, and the first placement plate 301 and the second placement plate 302 are respectively provided with a first receiving groove 303 and a second receiving groove 304 on the sides close to each other, and the first placement plate 301 and the second placement plate 302 are both provided with a plurality of hollow holes on the sides away from each other;

[0028] A plurality of battery placement components 3 are distributed on the base 1 in a matrix manner. The battery placement components 3 are used to carry batteries to be tested. Each battery placement component 3 can carry a preset number of batteries, and the batteries are placed in the battery placement component 3 in a stacked manner, that is, a plurality of batteries are stacked and placed between the first placement plate 301 and the second placement plate 302;

[0029] By opening hollow holes from top to bottom on the sides of the first placement plate 301 and the second placement plate 302 that are away from each other, the first placement plate 301 and the second placement plate 302 can be designed as a hollow structure. The purpose of this design is to increase the contact area between the battery and the test environment so that the outer surface of the battery is better exposed to the environment.

[0030] It can be understood that increasing the contact area can firstly effectively improve the heat conduction efficiency between the battery and the surrounding environment and promote faster and more efficient heat exchange, which helps to quickly transfer the heat generated inside the battery to the environment, prevent the battery from overheating, and improve the overall heat dissipation performance of the battery; secondly, a larger contact area can also improve the heat exchange efficiency of the gas between the battery and the test environment. Increasing the contact area can improve the heat exchange efficiency, thereby improving the interaction performance between the battery and the environment.

[0031] In one embodiment of the present invention, Figure 4 As shown, by clamping the cylindrical battery 11 by the first placement plate 301 and the second placement plate 302, a plurality of cylindrical batteries 11 can be stably placed on the first placement plate 301 and the second placement plate 302, and the negative electrode of the cylindrical battery 11 is placed inside the second receiving groove 304, and the positive electrode is placed inside the first receiving groove 303;

[0032] It can be understood that the second placement plate 302 and the first placement plate 301 can not only place cylindrical batteries 11, but also batteries of other shapes, such as square columns. It should be noted that the length of the battery placed between the first receiving groove 303 and the second receiving groove 304 should be slightly larger than the distance between the inner walls opposite to the first receiving groove 303 and the second receiving groove 304. The lateral width of the first receiving groove 303 is equal to the diameter of the positive electrode of the cylindrical battery 11, and the lateral width of the second receiving groove 304 is equal to the diameter of the negative electrode of the cylindrical battery 11. Therefore, the positive electrodes of the cylindrical battery 11 can stably fall into the first receiving groove 303 and the second receiving groove 304.

[0033] In addition, the first placement plate 301 and the second placement plate 302 of each group of battery placement components 3 can be designed according to the diameters of cylindrical batteries 11 of different sizes. For example, the first placement plate 301 and the second placement plate 302 of each column or row can be designed according to the same type of cylindrical batteries 11, and the first placement plate 301 and the second placement plate 302 can accommodate corresponding cylindrical batteries 11.

[0034] Preferably, a second supporting plate 9 is disposed inside the first receiving groove 303, and the second supporting plate 9 is located at the bottom of the first receiving groove 303, and a first supporting plate 7 is disposed inside the second receiving groove 304, and the first supporting plate 7 is located at the bottom of the second receiving groove 304. The purpose of the above design is to prevent the cylindrical battery 11 placed at the bottom between the first placement plate 301 and the second placement plate 302 from directly contacting the base 1.

[0035] Preferably, a plurality of first positioning slots 12 are provided on the surface of the base 1, a first positioning plug plate 8 is provided at one end of the second placement plate 302, and the second placement plate 302 is detachably connected to the base 1 through the cooperation of the first positioning plug plate 8 and the first positioning slot 12, a plurality of second positioning slots 13 are provided on the surface of the base 1, a second positioning plug plate 10 is provided at one end of the first placement plate 301, and the first placement plate 301 is detachably connected to the base 1 through the cooperation of the second positioning plug plate 10 and the second positioning slot 13;

[0036] Through the design of the above-mentioned plug-in structure, the first placement plate 301 and the second placement plate 302 can be conveniently and stably positioned on the base 1 at appropriate positions;

[0037] The cross section of the first positioning plug plate 8 is the same as that of the first positioning slot 12, and the cross section of the second positioning plug plate 10 is the same as that of the second positioning slot 13, so after the second positioning plug plate 10 or the first positioning plug plate 8 is inserted into the second positioning slot 13 or the first positioning slot 12, the second positioning plug plate 10 or the first positioning plug plate 8 will not shake left and right or forward and backward inside the second positioning slot 13 or the first positioning slot 12, and the height of the first positioning plug plate 8 is greater than the depth of the first positioning slot 12, and the height of the second positioning plug plate 10 is greater than the depth of the second positioning slot 13, so that the second positioning plug plate 10 or the first positioning plug plate 8 can be inserted into the second positioning slot 13 or the first positioning slot 12 with interference fit, thereby ensuring the stability of the connection between the first placement plate 301 and the second placement plate 302 on the base 1;

[0038] Furthermore, the tops of the first positioning slot 12 and the second positioning slot 13 are both provided with chamfers, so that the staff can more smoothly insert or remove the first positioning plug plate 8 and the second positioning plug plate 10 inside the first positioning slot 12 and the second positioning slot 13.

[0039] Preferably, a plurality of universal casters 5 are installed on the outer side of the base 1, and the universal casters 5 have a self-locking function. A connecting piece 2 is provided on the surface of the base 1, and a push rod 6 is detachably connected to the outer side of the connecting piece 2, so that the base 1 can be pushed and moved conveniently and freely on the ground. The connecting piece 2 can be a sleeve with a threaded groove, and a threaded fixing hole is provided on the surface of the push rod 6, that is, the push rod 6 can be detachably connected to the connecting piece 2 by inserting bolts into the threaded groove and the threaded fixing hole. In this way, when the placement rack is not needed, the bolts can be loosened to place the push rod 6 on the base 1 to reduce the space occupied.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment of the utility model, a tensioning assembly 4 is provided on the outer side of the battery placement assembly 3, and the tensioning assembly 4 is used to provide a clamping force for the first placement plate 301 and the second placement plate 302 toward each other;

[0041] The tensioning assembly 4 includes: the first placing plate 301 and the second placing plate 302 are respectively connected to the first plate body 401 and the second plate body 402 on the sides away from each other, and the surfaces of the first plate body 401 and the second plate body 402 are jointly installed with an elastic telescopic rod 403. Preferably, a set of tensioning assemblies 4 includes two elastic telescopic rods 403;

[0042] The first plate body 401 and the second plate body 402 are respectively provided with a first snap-in 404 and a second snap-in 405 on the sides close to each other, and the length of the first snap-in 404 is the same as the length of the first placement plate 301, and the length of the second snap-in 405 is the same as the length of the second placement plate 302. Through the first snap-in 404 and the second snap-in 405, the first plate body 401 and the second plate body 402 can be quickly clamped at the appropriate positions on the first placement plate 301 and the second placement plate 302, and the friction force of contact is used to achieve an interference fit, so that the first plate body 401 and the second plate body 402 can move longitudinally, and the friction force is used to achieve a preliminary fixation of the position.

[0043] In this embodiment, when the battery is placed between the first placement plate 301 and the second placement plate 302, since the length of the battery is slightly larger than the distance between the inner walls of the first receiving groove 303 and the second receiving groove 304, the battery will slightly push the first placement plate 301 and the second placement plate 302 outward, thereby causing the spring inside the elastic telescopic rod 403 to stretch, that is, the elastic telescopic rod 403 generates a pulling force and provides a clamping force toward each other for the first placement plate 301 and the second placement plate 302, thereby better fixing the battery between the first placement plate 301 and the second placement plate 302.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
