Description

Technical Field

[0001] The utility model relates to the field of battery test boxes, in particular to a battery high and low temperature test box. Background Art

[0002] A battery high and low temperature test chamber is a device used to test the high and low temperature resistance of batteries, usually composed of one or more batteries. This test chamber can test batteries under high and low temperature environments to evaluate the performance and life of the batteries under various environmental conditions. The battery high and low temperature test chamber can simulate various temperature and humidity conditions, such as high temperature, low temperature, low air pressure, high air pressure, etc., to test the battery's capacitance, voltage, cycle life and other parameters under different conditions. The test chamber usually has an automatic control system and data recording function, which can record the battery performance parameters under each test condition for analysis and comparison.

[0003] When the existing battery high and low temperature test box performs high temperature tests on batteries, the temperature inside the test box body is usually high, and some batteries of poor quality may cause dangers such as battery rupture, leakage, fire or even explosion due to the high temperature, causing the test box to easily shake greatly. The impact force of the battery explosion will collide with the inside of the test box body, thereby reducing its service life. In addition, the battery explosion will suddenly generate a large amount of heat and harmful gases, and the experiment can only be continued after these harmful gases are completely dissipated, which affects the progress and experimental results of the battery test and increases time and cost.

[0004] Therefore, it is necessary to provide a new battery high and low temperature test box to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a battery high and low temperature test box.

[0006] The battery high and low temperature test box provided by the utility model comprises a test box body, a heat dissipation component is arranged through the top of the test box body, a central partition is arranged inside the test box body, and the central partition divides the inside of the test box body into a high temperature chamber and a low temperature chamber, and a plurality of protective components distributed along the side wall of the high temperature chamber of the test box body are arranged inside the high temperature chamber of the test box body;

[0007] The protective assembly includes a protective outer plate and a plurality of first sleeves, wherein the plurality of first sleeves are respectively fixedly connected to the inner wall of the high-temperature cavity of the test box body, a plurality of first cylinders are fixedly connected to one end of the protective outer plate, and the first cylinders are fitted into the annular holes opened on the inner wall of the first sleeve, elastic members are provided on the outer walls of the first cylinder and the elastic member, a plurality of connecting grooves are penetrated through the protective outer plate, and a plurality of protective inner plates are respectively fixedly connected to one end of the protective outer plate away from the first cylinder, and the protective inner plates are located on the outside of the connecting grooves.

[0008] Furthermore, the heat dissipation component includes a heat dissipation fan and multiple activated carbon plates. A flow groove connected to the high-temperature chamber is opened through the top of the test box body. The heat dissipation fan and multiple activated carbon plates are arranged on the inner wall of the flow groove of the test box body in sequence from bottom to top.

[0009] Furthermore, the cross-section of the protective inner plate is arranged in a trapezoidal shape, and the size of the protective inner plate is larger than the flow groove of the protective outer plate.

[0010] Furthermore, two observation windows are respectively arranged on one side of the test box body, and the two observation windows are respectively located outside the high temperature cavity and the low temperature cavity, and auxiliary handrails are respectively fixedly connected to the edge of one side of the test box body.

[0011] Furthermore, a control screen is provided at one end of the test box body away from the auxiliary armrest, and the control screen is electrically connected to the heat dissipation fan.

[0012] Furthermore, four corners of the bottom of the test box body are respectively fixedly connected with universal wheels.

[0013] Compared with the related art, the battery high and low temperature test box provided by the utility model has the following beneficial effects:

[0014] 1. When the battery needs to undergo a high-temperature test, the test box body is opened and the battery is placed in a high-temperature chamber, and then the test box body is closed to make the interior of the test box a closed space, and the interior is heated. When a battery explodes during the test, the scattered matter from the battery explosion collides and splashes onto the protective outer plate and the outer wall of the protective inner plate. The protective inner plate is on the outside of the flow tank, so that the sputtered matter is blocked by the protective inner plate and will not pass through the flow tank into the high-temperature chamber, thereby improving the stability of the test.

[0015] 2. The impact force generated by the explosion of the battery is transmitted to the protective inner plate and the protective outer plate. The protective outer plate squeezes the elastic member to generate elastic potential energy. During the movement of the protective outer plate, the first cylinder slides on the first sleeve and guides it. The elastic potential energy generated by the elastic member resets the protective outer plate to reduce the vibration of the test box body.

[0016] 3. During the test of the battery high and low temperature test box, the hot air accumulated inside will be dispersed to both sides of the protective inner plate and transmitted to the high-temperature cavity through the flow groove. After the battery test, the heat dissipation component is started to exchange the air inside and outside, so that the internal hot air can circulate quickly and exchange with the external cold air, thereby improving its internal cooling effect.
