DETAILED DESCRIPTION
[0022] 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 specific 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.
[0023] In order to make the description of the disclosed content more detailed and complete, the following is an illustrative description of the implementation methods and specific examples of the utility model; however, this is not the only form of implementing or using the specific examples of the utility model. Based on the examples in the utility model, all other examples obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.
[0025] In the description of the embodiments of the present invention, "multiple" means two or more than two, and other quantifiers are similar and should be understood. The preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features therein may be combined with each other if there is no conflict.
[0026] like Figure 1 and Figure 2The figure shows a three-dimensional structural diagram of a forced discharge device provided by an embodiment of the utility model in different directions, wherein the forced discharge device comprises: a discharge bracket 100; a support plate 200, wherein the support plate 200 is movably connected to the discharge bracket 100; a discharge module 300, wherein the discharge module 300 is arranged on the support plate 200, and wherein the discharge module 300 comprises at least one discharge resistor 310; and a conductive component 400, wherein the conductive component 400 has an electric energy input terminal and an electric energy output terminal, wherein the electric energy output terminal is electrically connected to a first discharge resistor 311 in the discharge module 300, and wherein the electric energy output terminal is elastically connected to the first discharge resistor 311.
[0027] It should be noted that the discharge bracket 100 can be any bracket that can accommodate the battery cell and the discharge device of the battery cell. As a specific example, Figure 1 As shown, the overall shape of the discharge bracket 100 can be a cube or a cuboid, and the discharge bracket 100 can have a hollow structure for accommodating battery cells. On the side close to the battery cell pole, the discharge bracket 100 can be connected to a discharge module 300 that can be electrically connected to the battery cell pole so as to discharge the battery cell through the discharge module 300.
[0028] Specifically, the support plate 200 may be any plate-shaped structure capable of supporting the discharge module 300, and in order to discharge the battery cell through the discharge module 300, the support plate 200 may be disposed on one side of the discharge bracket 100 close to the battery cell pole;
[0029] It should be noted that the connection method of the support plate 200 to the discharge bracket 100 can be any feasible method. For example, a guide rail can be set on the discharge bracket 100, and the support plate 200 can be set in the guide rail, so that the support plate 200 can be moved on the discharge bracket 100, and by setting the direction of the guide rail on the discharge bracket 100, the support plate 200 can be moved along the expected direction on the discharge bracket 100.
[0030] It is understandable that since the support plate 200 can be moved on the discharge bracket 100, the support plate 200 can be moved according to the height or width of the battery cell, and the position of the support plate 200 on the discharge bracket 100 can be changed to better discharge the battery cell, ultimately achieving discharge of battery cells of various specifications.
[0031] It should be noted that the conductive component 400 can be any component that can conduct electricity between the discharge module 300 and the battery cell, and is not limited in detail here; it should be further noted that the power input end of the conductive component 400 can be connected to the pole of the battery cell so that the electric energy of the battery cell flows into the conductive component 400, and the power output end of the conductive component 400 is electrically connected to the first discharge resistor 311, so that the electric energy flowing into the conductive component 400 can flow out to the first discharge resistor 311, and the electric energy is released in the form of power consumption by the first discharge resistor 311.
[0032] It can be understood that the number of the discharge resistors 310 can be one or more. When the number of the discharge resistors 310 is more than one, each discharge resistor 310 can be connected to a corresponding conductive component 400, and each discharge resistor 310 can discharge one battery cell, so that the discharge of multiple battery cells can be achieved, and finally the batch discharge of battery cells can be achieved;
[0033] It should be noted that the discharge resistor 310 can be replaced according to the specifications of the battery cell and the amount of electric energy that needs to be released, so that the specifications of the discharge resistor 310 meet the electric energy that needs to be released.
[0034] It should be noted that the way in which the power output terminal is elastically connected to the first discharge resistor 311 can be any way that makes the connection between the power output terminal and the first discharge resistor 311 elastic, for example, the power output terminal and the first discharge resistor 311 are connected through a connecting block, and the connecting block is made of elastic material.
[0035] It can be understood that the electric energy output end is elastically connected to the first discharge resistor 311, so that the conductive component 400 can buffer the pressure when it is subjected to the pressure of the battery cell pole connected to it, so as to prevent the conductive component 400 from generating a reaction force on the battery cell pole when subjected to pressure and damaging the battery cell pole.
[0036] In this way, the embodiment of the utility model directly discharges the battery through the discharge resistor 310, avoiding the complexity of the discharge structure. Compared with the complex structure of the charging and discharging cabinet for discharging the battery in the prior art, the forced discharge device of the embodiment of the utility model can use all the space for discharge when occupying the same space as the charging and discharging cabinet, so that more discharge resistors 310 can be set for discharge. Naturally, compared with the charging and discharging cabinet in the prior art, the forced discharge device in the embodiment of the utility model can release more electrical energy from the battery, thereby effectively reducing the discharge time of the battery and improving the discharge efficiency of the battery.
[0037] In an optional implementation, the discharge resistor 310 is a power resistor.
[0038] It should be noted that the power of the discharge resistor 310 in this implementation can be designed according to the specific needs of the application. For example, if the battery cell discharged through the discharge resistor 310 needs to release more electric energy, the power of the discharge resistor 310 can be made larger. If the battery cell discharged through the discharge resistor 310 needs to release less electric energy, the power of the discharge resistor 310 can be made smaller.
[0039] It can be understood that a power resistor is a resistor that consumes a large amount of power. Therefore, in this implementation, setting the discharge resistor 310 as a power resistor can further enhance the discharge efficiency of the discharge module 300 on the battery cell.
[0040] In an optional implementation, Figure 1 and Figure 2 As shown, the forced discharge device further includes a movable connecting member 500 , one end of which is detachably connected to the support plate 200 , and the other end of which is connected to the discharge bracket 100 .
[0041] It should be noted that in this implementation, the detachable connection method between the movable connecting member 500 and the support plate 200 can be any detachable connection method, and the connection method between the movable connecting member 500 and the discharge bracket 100 can be any connection method;
[0042] It can be understood that the support plate 200 is detachably connected to one end of the movable connecting member 500, and the other end of the movable connecting member 500 is connected to the discharge bracket 100. The position of the support plate 200 on the discharge bracket 100 can be changed by detaching the support plate 200 from one end of the movable connecting member 500, thereby realizing the movement of the support plate 200 on the discharge bracket 100.
[0043] In an optional implementation, Figure 1 and Figure 2 As shown, a movable through hole 210 is provided on the support plate 200 , and one end of the movable connecting member 500 is detachably connected in the movable through hole 210 , and the other end of the movable connecting member 500 is fixedly connected to the discharge bracket 100 .
[0044] It should be noted that the length of the movable through hole 210 in this implementation can be determined according to the distance that the support plate 200 needs to move on the discharge bracket 100, and the opening direction of the movable through hole 210 can be determined according to the direction that the support plate 200 needs to move on the discharge bracket 100;
[0045] It is understandable that when the support plate 200 needs to be moved, the movable connecting member 500 and the movable through hole 210 can be disassembled to move the support plate 200. When the support plate 200 moves to the expected position, the movable connecting member 500 and the movable through hole 210 are re-fastened, so that the support plate 200 can be moved on the discharge bracket 100.
[0046] In an optional implementation, Figure 3 Shown Figure 2 The local enlarged view of point A in the middle is as follows: Figures 1 to 3 As shown, the conductive component 400 includes: a buffer 410 , one end of which is electrically connected to the first discharge resistor 311 ; a test probe 420 , which has an electric energy test end and a fixed end, and the fixed end is connected to the other end of the buffer 410 .
[0047] It should be noted that the buffer member 410 may be any component having a buffering function, for example, the buffer member 410 may be a structural member made of an elastic material;
[0048] It should be noted that the power test end of the test probe 420 is an end electrically connected to the battery cell pole, and the test probe 420 can be selected according to specific needs of the application. For example, the test probe 420 can be a HRS420 test probe.
[0049] It is understandable that when the battery cell pole squeezes the test probe 420 , the squeezing force on the test probe 420 can be buffered by the buffer 410 , thereby preventing the test probe 420 from squeezing the battery cell pole and damaging the battery cell pole.
[0050] In an optional implementation, Figure 1 and Figure 2 As shown, the discharge module 300 also includes a cylinder 320, a fixed end of which is fixedly connected to the first discharge resistor 311, and a piston (not shown in the figure) is arranged in the cylinder 320, and the piston is connected to one end of the buffer 410 so that the buffer 410 moves in the cylinder 320.
[0051] It can be understood that by allowing the buffer 410 to move within the cylinder 320, the movement of the buffer 410 can be limited to prevent the buffer 410 from moving too much and damaging the test probe 420 connected thereto. It can also avoid the problem of the buffer 410 being directly connected to the discharge resistor 410 and causing the discharge resistor 410 to be damaged.
[0052] It is understandable that in order to achieve a better limiting effect of the cylinder body 320 on the buffer member 410 , the difference between the cylinder diameter of the cylinder body 320 and the end surface diameter of the buffer member 410 may be set within a preset error range.
[0053] In an optional implementation, the buffer member 410 is a spring.
[0054] It can be understood that a spring is an elastic element that can deform under the action of an external force and can return to its original shape. It has the characteristics of good elasticity, fatigue resistance and stability.
[0055] In an optional implementation, Figure 1 and Figure 2 As shown, the forced discharge device further includes a resistor fixing connection block 600 , and the resistor fixing connection block 600 is disposed between two surfaces of the first discharge resistor 311 and the support plate 200 that are close to each other.
[0056] It can be understood that the resistor fixing connection block 600 can fix the first discharge resistor 311 on the support plate 200;
[0057] It is understandable that since the resistor is easily damaged when it is hit, and the support plate 200 needs to play a supporting role and therefore usually has a certain rigidity, when the first discharge resistor 311 is directly installed on the support plate 200, the support plate 200 is likely to damage the first discharge resistor 311. For this reason, the material of the resistor fixing connection block 600 can be a flexible material to prevent the first discharge resistor 311 from being damaged.
[0058] In an optional implementation, Figure 1 and Figure 2 As shown, the resistor fixing connection block 600 is located in the middle of the first discharge resistor 311 .
[0059] It can be understood that if the resistor fixing connection block 600 is located outside the middle of the first discharge resistor 311, the supporting force provided by the resistor fixing connection block 600 to each part of the first discharge resistor 311 is uneven, so that the supporting and fixing effect of the resistor fixing connection block 600 on the first discharge resistor 311 is poor. If the resistor fixing connection block 600 is located in the middle of the first discharge resistor 311, the above problem can be avoided.
[0060] In an optional implementation, Figure 1 and Figure 2 As shown, the discharge module 300 further includes an extension arm 330 , and the extension arm 330 is disposed between the end of the first discharge resistor 311 and the fixed end of the cylinder 320 .
[0061] It is understandable that since the buffer 410 moves in the cylinder 320, the cylinder 320 will still be affected by the vibration caused by the buffer 410. Therefore, when the cylinder 320 is directly connected to the first discharge resistor 311, the first discharge resistor 311 will still be damaged. Therefore, an extension arm 330 is provided between the end of the first discharge resistor 311 and the fixed end of the cylinder 320 to avoid damage to the first discharge resistor 311 caused by the cylinder 320 when the cylinder 320 is directly connected to the first discharge resistor 311.
[0062] The technical solution provided by the present invention is introduced in detail above. The principle and implementation mode of the present invention are explained by using specific examples in the present invention. The description of the above embodiments is only used to help understand the structure and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
[0063] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
