The battery is protected by the battery casing. The fire performance testing equipment will test the ability of the battery casing to extinguish after being ignited. There are many ways to judge based on the burning speed, burning time, anti-drip ability and whether the dripping beads are burning.

[0003] Chinese patent number CN202223584853.3 discloses a detection device for fireproof sealing strips, including a detection box, a smoke hole is formed through the top plate of the detection box, an exhaust fan is fixedly arranged just above the upper end of the smoke hole, a smoke box is fixedly arranged on the upper surface of the top plate of the detection box outside the exhaust fan, a smoke outlet is fixedly arranged at the center of the rear plate of the smoke box, side protective shells are fixedly arranged on both sides of the detection box, a hydraulic cylinder is fixedly arranged in the internal cavity of the side protective shell, a stretching shaft is fixedly connected to the end of the output shaft of the hydraulic cylinder, a fixed clamp seat is fixedly connected to the end of the shaft body of the stretching shaft, a movable clamp plate is slidably arranged inside the fixed clamp seat, and a fastening bolt is rotatably arranged on the upper end surface of the fixed clamp seat.

[0004] From the above, it can be seen that the flame nozzle structure can simulate the high temperature environment of the fire-resistant sealing strip when encountering a fire, so that it can most realistically show the changes in mechanical properties under fire conditions. At the same time, the fire-resistant sealing strip can be clamped by a stretching device and axially stretched in a high temperature environment of flame burning, so as to further determine the degree of change of its mechanical properties in a high temperature environment. However, the case still has the following shortcomings: First, when the outer box of the battery is being transported, the equipment overheats after heating and testing, and personnel who open it for operation are prone to burns, which is not conducive to continuous testing; second, when the outer box of the battery continues to burn, the existing technology can only extinguish the fire by burning it out or spraying it with water, which is too limited in operation.

[0005] Therefore, in order to solve the above problems, a fire resistance performance testing device for battery outer box production is proposed. Utility Model Content

[0025] During operation, the load-bearing plate 21 and the connecting seat 22 are installed to support the components on the top during the test. The connection between the support rod 24 and the isolation plate 25 isolates the test space from other components to avoid the influence of excessive heat on other components during the heating test.

[0026] Furthermore, the protection component 3 is installed with a mounting plate 31, a cylinder 32 is fixedly installed on the top of the mounting plate 31, a movable rod 33 is movably installed at the output end of the cylinder 32, and one end of the movable rod 33 is fixedly connected to a linkage plate 37;

[0027] During operation, the cylinder 32 moves the movable rod 33 , whereby the other end of the movable rod 33 drives the linkage plate 37 to perform corresponding synchronous movement.

[0028] Further, the detection box 1 is installed with a fixing frame 11, the fixing frame 11 is fixedly connected with three protective plates 12, the top of the fixing frame 11 is fixedly connected with a connecting plate 13, one side of the fixing frame 11 is fixedly installed with a control panel 14, and one side of the fixing frame 11 is fixedly connected with a bearing plate 21;

[0029] During operation, the protective plate 12, the connecting plate 13 and the bearing plate 21 cooperate with the movable plate 201 to seal the interior during testing, which is beneficial for providing certain protection for the staff during the heating test.

[0030] Furthermore, a fixed block 27 is fixedly connected to the top of the bearing plate 21, a hydraulic cylinder 28 is hingedly connected to one side of the fixed block 27, a hydraulic push rod 29 is movably installed at the output end of the hydraulic cylinder 28, and a movable plate 201 is hingedly connected to one end of the hydraulic push rod 29;

[0031] During operation, the hydraulic cylinder 28 is hinged to the fixed block 27 , and the hydraulic push rod 29 limits the hydraulic cylinder 28 when it is retracted to its original position. At the same time, the hydraulic cylinder 28 moves in a circle around the fixed block 27 as the hydraulic push rod 29 moves.

[0032] Furthermore, a fixed shaft 202 is passed through and hingedly connected to the bottom of the movable plate 201, and fixed frames 11 are fixedly installed at both ends of the fixed shaft 202;

[0033] During operation, when the hydraulic push rod 29 generates thrust on the movable plate 201, the movable plate 201 performs circular movement and turns around the fixed axis 202, and the adjustment is convenient for taking out the outer box of the battery.

[0034] Furthermore, one side of the mounting plate 31 is provided with four grooves 36, the inner walls of the four grooves 36 are respectively fixedly mounted with sealing sleeves 35, the inner walls of the four sealing sleeves 35 are respectively movably mounted with plugs 34, and the bottoms of the four plugs 34 are fixedly connected with linkage plates 37;

[0035] During operation, the movable rod 33 drives the linkage plate 37 to move, thereby linking the plug 34 to move in the inner wall of the sealing sleeve 35, so that the gap between the plug 34 and the sealing sleeve 35 allows oxygen to flow, which is beneficial to the control of heating monitoring.

[0036] Working principle: In the first embodiment, the hydraulic cylinder 28 is driven to make the hydraulic push rod 29 at the output end perform telescopic and divergent activities. When the hydraulic push rod 29 moves to one side, it generates thrust to the movable plate 201 hinged on one side, so that the movable plate 201 performs circular activities with the fixed axis 202 as the axis. When the activities reach a certain extent, the hydraulic push rod 29 is parallel to the load-bearing plate 21. At this time, the outer box of the battery is placed on the top of the isolation plate 25, and the flamethrower 26 is driven to continuously heat the outer box of the battery. During the heating process, the servo motor 23 can be driven to make the output shaft drive the flamethrower 26 to rotate, so as to avoid the heating surface becoming controllable and adjustable during continuous local heating. After the test is completed, the hydraulic push rod 29 is pushed to be parallel to the load-bearing plate 21 through the above-mentioned method, and the outer box of the battery is taken out from the top of the isolation plate 25 to proceed to the next step.

[0037] Embodiment 2: In the process of heating the outer box of the battery by the flamethrower 26, a certain amount of oxygen is required to promote combustion. The movable rod 33 is driven by the cylinder 32 to push the linkage plate 37 at the bottom. The linkage plate 37 is linked to the plug 34 to move in the inner wall of the sealing sleeve 35 during the movement, so that a gap is generated between the plug 34 and the sealing sleeve 35 for air circulation. At the same time, when the outer box of the battery is heated and tested, when the combustion of the outer box of the battery is uncontrollable, the cylinder 32 is driven to shrink the movable rod 33. Under the cooperation, the plug 34 and the sealing sleeve 35 are tightly fitted, the air inlet channel is closed, and the combustion of the outer box of the battery is controlled without the supply of oxygen.
