[0002] At present, new energy vehicles are becoming more and more popular. The safety of battery packs directly affects the safety of the entire vehicle. Major new energy vehicle manufacturers have gradually improved various testing standards, and battery pack extrusion test is a crucial one among them.

[0003] The prior art (publication number: CN 219142477 U) discloses a battery extrusion and puncture tester, comprising: a cabinet, an inner bracket, a screw drive assembly and a press assembly; the press assembly comprises: an upper press and a lower press, the lower press is fixedly mounted on a carrier, the upper press is arranged on the screw drive assembly and driven to move up and down by the screw drive assembly; the upper press is symmetrically distributed up and down, and a fixed clamp limits the workpiece to be tested between the two; the screw drive assembly comprises: a servo motor, a screw and a pressure frame, the upper press is assembled on the pressure frame, and a pressure sensor is arranged on the upper press or the lower press.

[0004] Although the above patent adopts the cooperation of two guide columns and two pressure rods, the servo motor outputs power, and transmits the power to the upper press through the gearbox and the screw rod, making the control more precise and stable; the extrusion force is divided into upper force output and lower force, so that the extrusion force is completely realized between the two pressure rods, so that the entire chassis is not affected by the extrusion force, more stable, and the plane is uniform, but there are the following disadvantages. After the battery test spontaneously combusts, the natural battery cannot be automatically thrown into a closed environment. The spontaneously combusted battery may continue to damage the tester and surrounding equipment, increase the cost of maintenance and replacement, and need further improvement. For this reason, we propose a vertical new energy battery expansion tester. Utility Model Content

[0005] The main purpose of the utility model is to provide a vertical new energy battery expansion testing machine, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A vertical new energy battery expansion testing machine comprises a box body, a top plate is installed at the upper end of the box body, a second rectangular groove is opened in the middle of the lower end of the top plate, a slide plate is slidably connected to the middle of the upper end of the top plate, a pushing component is installed at the right upper end of the top plate, a pressure sensor is installed at the upper end of the slide plate, a placement plate is arranged at the upper end of the pressure sensor, an L-shaped frame is arranged at the rear upper end of the top plate, a hydraulic cylinder is installed at the upper end of the L-shaped frame, and the output end of the hydraulic cylinder movably passes through the upper wall of the L-shaped frame and is transmission-connected with a pressure block.

[0008] Preferably, the pushing component includes a cylinder, which is installed on the upper right part of the top plate, an L-shaped plate is installed on the outer surface of the cylinder, a push plate is installed on the left end of the L-shaped plate, and the output end of the cylinder is fixedly connected to the right end of the slide plate.

[0009] Preferably, a fixing plate is installed at the left end of the box body, a water tank is installed at the upper left part of the fixing plate, a pump body is installed at the upper right part of the fixing plate, the suction end of the pump body extends into the water tank, and the discharge end of the pump body extends into the box body.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By setting a pushing component, the self-igniting battery can be pushed into the box. When the battery self-ignites, the output end of the control cylinder is shortened, driving the slide plate, the placement plate and the battery to move to the right. When the battery contacts the push plate, the push plate prevents the battery from continuing to move to the right, so that the battery is separated from the top of the placement plate, and then falls from the second rectangular groove into the box. Then the output end of the control cylinder is extended, so that the slide plate blocks the top of the second rectangular groove, and the battery can be automatically pushed into the closed box, avoiding the self-igniting battery from continuously causing damage to the test machine and surrounding equipment, and reducing the subsequent maintenance and replacement costs;

[0015] 2. By setting up a spray component, the duration of battery spontaneous combustion can be reduced. Before the test, pour the fire extinguishing agent into the water tank, control the pump body to transport the fire extinguishing agent in the water tank into the box, and then spray it on the spontaneously combusting battery, quickly reduce the fire scene temperature, suppress heat radiation, reduce the subsequent combustion time, and facilitate subsequent personnel to quickly deal with it.
