[0002] Lithium batteries are the most commonly used type of power batteries in electric devices. They have the advantages of high energy density, fast charging rate and strong discharge performance, and they have no charge and discharge memory effect. They are the first choice for mobile power sources for various power tools, toys and new energy equipment. However, it is precisely because of the powerful energy storage capacity and discharge performance of lithium batteries that the safety of lithium batteries has been repeatedly questioned, especially the tolerance and performance of lithium batteries under extreme conditions such as puncture, extrusion, high temperature, overcharge and over-discharge. This is one of the key contents of lithium battery research and development. Therefore, it is very necessary to test the safety performance of lithium batteries.

[0023] refer to Figure 3 The limit assembly 9 includes a limit slider 91, the inner side of the limit slider 91 is fixedly connected to the top of both sides of the push plate 6, a limit groove 92 is opened on the top of the inner side of the limit plate 5, the inner wall of the limit groove 92 is slidably connected to the surface of the limit slider 91, and the limit slider 91 is T-shaped.

[0024] As a technical optimization solution of the present invention, by setting a limit assembly 9, the limit slider 91 will be driven to move along the inner wall path of the limit groove 92 during the movement of the push plate 6, thereby preventing the push plate 6 from deviating up, down, left and right during the movement, thereby affecting the stability of the push plate 6 and improving the use effect.

[0025] refer to Figure 2 The guide assembly 11 includes a guide inclined plate 111 , the top of the front side of the guide inclined plate 111 is fixedly connected to the top of the back side of the tester body 1 , and both sides of the top of the guide inclined plate 111 are fixedly connected with anti-fall plates 112 .

[0026] As a technical optimization solution of the utility model, by setting the guide component 11, the guide inclined plate 111 can be used to tilt and guide the pushed out battery waste, so as to prevent the battery waste from directly hitting the ground and causing further damage to the battery waste and affecting subsequent recycling. Then, the anti-fall plate 112 can ensure that the battery waste is moved on the top of the guide inclined plate 111 during the process of being pushed out, thereby improving the guiding stability.

[0027] refer to Figure 2 The buffer mechanism 10 includes an extension plate 101, the front side of the extension plate 101 is fixedly connected to the bottom of the back side of the guide inclined plate 111, the top of the extension plate 101 is inlaid with a rubber plate 102, and both sides of the top of the extension plate 101 are fixedly connected with anti-deflection plates 103.

[0028] As a technical optimization solution of the utility model, by providing a buffer mechanism 10, when the waste batteries move to the bottom of the guide inclined plate 111 during the discharge process, the waste batteries will have a certain inertia, and then the waste batteries can release the inertia on the extension plate 101, so that the moving waste batteries gradually stop, and at the same time, the bottom of the waste batteries contacts the extension plate 101 through the rubber plate 102, thereby further improving the friction between the waste batteries and the extension plate 101, so that the waste batteries can stop earlier, and at the same time, the anti-deflection plate 103 can be used to limit the waste batteries to the left and right.

[0029] refer to Figure 2 A tension spring 12 is fixedly connected to the outer side of the limit slider 91 , and one end of the tension spring 12 away from the limit slider 91 is fixedly connected to the front sides of both sides of the inner wall of the tester body 1 .

After the waste battery is pushed out, the user starts the electric telescopic rod 8 to retract, and then the push plate 6 will be reset under the tension of the tension spring 12 to facilitate the next use.

[0031] refer to Figure 2 The back side of the limiting plate 5 is fixedly connected with a limiting sleeve 13 , the limiting sleeve 13 is sleeved on the surface of the transmission rope 7 , and the inner wall of the limiting sleeve 13 is slidably connected with the surface of the transmission rope 7 .

[0034] As a technical optimization solution of the utility model, by providing a soft pad 14, when the push plate 6 pushes the battery waste out, the push plate 6 contacts the battery waste through the soft pad 14, thereby being able to buffer the impact force generated during the contact, preventing the impact force from being too large and causing further damage to the battery waste, and then utilizing the advantage of the strong viscosity of PET glue to prevent the soft pad 14 from falling off.

[0035] The working principle and use process of the utility model are as follows: when the user starts the tester body 1 to drive the pressure plate 3 to move downward to press the battery for detection, if the battery is damaged and the test fails, the battery will generate heat or leak electricity, then the user can turn on the electric telescopic rod 8 to contract and pull one end of the transmission rope 7, and then the other end of the transmission rope 7 will drive the push plate 6 to move backward, so that the push plate 6 will push the waste battery outward, and then the guide inclined plate 111 can be used to tilt and guide the pushed waste battery to prevent the waste battery from directly hitting the ground and causing further damage to the waste battery and affecting subsequent recycling, and then the anti-fall plate 112 can be used to ensure that the waste battery is moved on the top of the guide inclined plate 111 during the process of pushing out the waste battery, thereby improving the guiding stability, and on the push plate During the movement of 6, the limiting slider 91 will be driven to move along the inner wall path of the limiting groove 92, thereby preventing the push plate 6 from deviating up, down, left, and right during the movement, thereby affecting the stability of the push plate 6 and improving the use effect. When the waste battery moves to the bottom of the guide inclined plate 111 during the discharge of the waste battery, the waste battery will have a certain inertia, and then the waste battery can be released by inertia on the extension plate 101, so that the moving waste battery gradually stops. At the same time, the bottom of the waste battery contacts the extension plate 101 through the rubber plate 102, thereby further increasing the friction between the waste battery and the extension plate 101, so that the waste battery can stop earlier. At the same time, the anti-deflection plate 103 can be used to limit the waste battery to the left and right, which has the ability to assist in the discharge of waste batteries.

[0036] To sum up: the battery performance testing device, by setting an electric telescopic rod 8, turns on the electric telescopic rod 8 to contract and pulls one end of the transmission rope 7, and then the other end of the transmission rope 7 will drive the push plate 6 to move backward, so that the push plate 6 will push the waste battery outward, solving the problem of lack of a structure for discharging waste batteries. When the battery is damaged after testing in the testing device, the internal structure of the battery will cause a short circuit between the positive and negative electrodes due to damage. In this case, the battery will heat up or leak electricity, and the waste battery cannot be discharged in time.
