DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a battery high-temperature aging test box, comprising a test box body 1, a plurality of rollers 101 are equidistantly installed in the test box body 1 for rotation, a support frame 2 is fixedly installed on the front of the test box body 1, a hydraulic push rod 201 is fixedly connected to the support frame 2, a support plate 3 is arranged above the hydraulic push rod 201, a test battery 9 is arranged in the test box body 1, a limit slide groove 4 is arranged on the inner wall of the test box body 1, a limit slider 502 is slidably installed in the limit slide groove 4, a hydraulic push rod 501 is fixedly installed on the front of the limit slider 502, a push rod 5 is fixedly connected to the other end of the hydraulic push rod 501, a connector 6 is fixedly installed on the front of the push rod 5, a dovetail slide groove 601 is arranged on the front of the connector 6, a dovetail slider 603 is slidably installed in the dovetail slide groove 601, and a triangular drag block 602 is fixedly connected to the front of the dovetail slider 603.

[0021] In this embodiment, after the test battery 9 is tested inside the test box body 1, the seal of the test box body 1 is opened, and the hydraulic push rod 201 is started to drive the pallet 3 to move up, so that the top of the pallet 3 is slightly lower than the bottom of the test battery 9, and then the hydraulic push rod 501 is started to push the push rod 5 forward. The forward movement of the push rod 5 will drive the push plate 504 to move, and the push plate 504 will resist the back of the test battery 9, thereby pushing the test battery 9 out of the test box body 1 and moving it onto the pallet 3. At this time, the pallet 3 can be lifted to move the test battery 9 together with the pallet 3 and placed in a suitable position. There is no need to wait for the battery to cool down. The test battery 9 to be tested is placed together with the pallet 3 on the upper end of the hydraulic push rod 201, and the triangular drag block 602 will hook the front edge of the test battery 9, thereby dragging the test battery 9 into the test box body 1 to realize automatic loading and unloading.

[0022] Among them, in order to achieve the purpose of adjusting the height of the test battery 9, the present device is implemented by adopting the following technical solutions: a connecting ring 301 is fixedly installed under the support plate 3, the connecting ring 301 cooperates with the hydraulic push rod 201, handles 302 are fixedly installed on both sides of the support plate 3, a convex edge is fixedly connected to the support plate 3 near the front edge, a threaded rod 401 is threadedly installed in the limiting slide groove 4, a threaded through hole 503 is opened in the limiting slider 502, and the threaded through hole 503 is threadedly matched with the threaded rod 401.

[0023] The handle 302 is convenient for the operator to move the support plate 3, and the connecting ring 301 cooperates with the hydraulic push rod 201 to install the support plate 3 above the hydraulic push rod 201. The test battery 9 placed on the support plate 3, when the triangular drag block 602 is against the back of the test battery 9, the convex edge limits the forward movement of the test battery 9. At this time, the inclined surface of the triangular drag block 602 is released from the rear edge of the test battery 9, which will cause the triangular drag block 602 to move up. After the triangular drag block 602 moves to the front of the test battery 9, under the push of the return spring 604, the triangular drag block 602 will move down and reset again, and jam the front edge of the test battery 9. The threaded rod 401 is threadedly matched with the threaded through hole 503. Rotating the threaded rod 401 can drive the limit slider 502 to move, thereby adjusting the height of the push rod 5 so that the bottom of the push rod 5 is slightly higher than the test battery 9, and test batteries 9 of different specifications can be automatically pushed in and out.

[0024] Among them, in order to achieve the purpose of pushing the test battery 9, the present device adopts the following technical solution: a push plate 504 is fixedly installed under the push rod 5, a return spring 604 is fixedly connected to the dovetail slider 603, and the other end of the return spring 604 is fixedly connected to the inner wall of the dovetail slot 601.

[0025] When the push rod 5 moves forward, the push plate 504 contacts the back of the test battery 9 to push the test battery 9 out of the test box body 1 . The return spring 604 can provide a certain thrust for the dovetail slider 603 .

[0026] The working principle and use process of the utility model are as follows: when using the device, it is necessary to place the device in a suitable position, after opening the sealed door of the test box body 1, start the hydraulic push rod 201 to drive the support plate 3 to move up, then start the hydraulic push rod 501 to drive the push rod 5 to move forward, the forward movement of the push rod 5 will drive the triangular drag block 602 to move, the inclined surface of the triangular drag block 602 is released from the rear edge of the test battery 9, and the triangular drag block 602 will move up, after the triangular drag block 602 moves to the front of the test battery 9, under the push of the return spring 604, the triangular drag block 602 will move down and reset again, jamming the front edge of the test battery 9, and then start the hydraulic push rod 501 again to drive the triangular drag block 602 to move forward, and finally stop the front edge of the test battery 9. The drag block 602 moves backward, and the triangular drag block 602 clamps the front edge of the test battery 9, so that the test battery 9 can be dragged into the test box body 1, and the hydraulic push rod 201 is started to drive the support plate 3 to move downward, and the test box body 1 can be closed to perform the aging test. After the test is completed, the sealed door of the test box body 1 is opened again, and the hydraulic push rod 201 is started to drive the support plate 3 to move upward, and the hydraulic push rod 501 is started to drive the push plate 504 to move. The push plate 504 will resist the back of the test battery 9, thereby pushing the test battery 9 out of the test box body 1 and moving it onto the support plate 3. At this time, the support plate 3 can be lifted to move the test battery 9 together with the test battery 9 and place it in a suitable position.
