[0026] The following refers to Figure 1 and Figure 2 The pull-out high-low temperature test box of the embodiment of the present application is described.

[0027] The pull-out high-low temperature test box according to the embodiment of the present application comprises a test box main body 100 and a support frame.

[0028] The inside of the test box main body 100 is provided with a containing cavity, the front end of the containing cavity is provided with an open mouth, the front side of the test box main body 100 is provided with a box door 110, the box door 110 is covered on the open mouth from front to back, the box door 110 can be installed on the test box main body 100 in an openable and closable manner through hinging or other suitable connecting mode, the test box main body 100 is a device commonly used in the art, and can be directly purchased from the market, and the specific structure thereof will not be described here.

[0029] The support frame is arranged in the test box, and the support frame comprises a connecting part 200 and a pull-out part, the connecting part 200 is arranged in the accommodating cavity and connected with the inner wall of the accommodating cavity, the pull-out part is arranged in the connecting part 200 and slides along the front and back directions, the pull-out part is provided with a jig for placing a battery, the rear end of the pull-out part is provided with a baffle 310, the baffle 310 is parallel to the box door 110, the pull-out part has a forward moving state and a backward moving state relative to the connecting part 200, in the backward moving state, the pull-out part is arranged in the accommodating cavity, and the box door 110 can be closed; in the forward moving state, the box door 110 is opened, the pull-out part moves forward and protrudes out of the accommodating cavity, and the baffle 310 moves to the opening and shields the opening to a certain extent. Wherein, the connecting part 200 and the pull-out part can be connected through a sliding rail and sliding block mechanism, a sliding groove mechanism or other suitable sliding mechanisms, and the sliding mechanism can be arranged between the edge of the baffle 310 and the inner wall of the accommodating cavity; the jig needs to be connected with a wire for testing the battery, and the wire can be a flexible wire, so that the wire does not hinder the forward and backward movement of the jig.

[0030] By arranging the pull-out part, when the battery needs to be disassembled, the pull-out part can be pulled out of the test box body 100, so that the battery can be disassembled; at the same time, by arranging the baffle 310, after the pull-out part is pulled out of the test box body 100, the baffle 310 moves to the opening formed after the test box body 100 opens the box door 110, and the opening is shielded to a certain extent, so that the heat exchange between the internal environment of the test box body 100 and the external environment is reduced, a lot of time is not wasted for re-stabilizing the environment in the subsequent operation of the test box, the test efficiency is improved, and the energy consumption is reduced.

[0031] In some embodiments of the utility model, the gap is arranged between the baffle 310 and the inner wall of the test box body 100. The inner wall of the test box body 100 is the inner wall of the accommodating cavity. It can be understood that if the edge of the baffle 310 is in sliding fit with the inner wall of the accommodating cavity, the baffle 310 and the accommodating cavity will combine to form a structure similar to a piston, so that the space between the baffle 310 and the rear wall of the accommodating cavity forms a negative pressure environment, which makes it difficult for the worker to pull out the pull-out part. In this embodiment, by arranging the gap, during the process that the worker pulls out the pull-out part, the air on the front side of the baffle 310 will flow to the rear side of the baffle 310 through the gap, so that the negative pressure environment is avoided between the baffle 310 and the rear wall of the accommodating cavity, and the worker can smoothly pull out the pull-out part; moreover, the way that the front side space and the rear side space of the baffle 310 are communicated in this embodiment is to leave a gap at the edge of the baffle 310 instead of arranging a through hole in the middle of the baffle 310, so that in the forward moving state, the gap can be covered by the front frame 210, and heat convection between the internal environment and the external environment through the gap is avoided.

[0032] In some embodiments of the utility model, connecting component 200 includes front frame 210, and the outer edge of front frame 210 is connected with the inner wall of test box main body 100;The movement of pull-out component relative to support frame has a forward movement state, and in the forward movement state, baffle 310 is covered on front frame 210. In the forward movement state, baffle 310 is covered on front frame 210 from back to front, and the inner edge of front frame 210 overlaps with the outer edge of baffle 310. In this way, baffle 310 and front frame 210 jointly shield the open mouth, and the effect of reducing heat exchange between the internal environment of test box main body 100 and the external environment is better. Wherein, the transverse dimension of baffle 310 can be set to be less than the transverse dimension of the outer periphery of front frame 210 and greater than the transverse dimension of the inner periphery of front frame 210, and the vertical dimension of baffle 310 is less than the vertical dimension of the outer periphery of front frame 210 and greater than the vertical dimension of the inner periphery of front frame 210, that is, baffle 310 can be covered on front frame 210 while leaving a gap between baffle 310 and the inner wall of the containing cavity.

[0033] In some embodiments of the utility model, the number of jigs is multiple. In this way, more batteries can be tested at one time.

[0034] In some embodiments of the utility model, the pull-out component includes multiple partitions 320, and the multiple partitions 320 are arranged in parallel from top to bottom, and the multiple jigs are arranged one by one on the upper side of the multiple partitions 320. In this way, the space between adjacent partitions 320 can be adapted to a flat battery, making full use of space, and the structure is reasonable and compact. The partition 320 can be a particle board or other suitable insulating material component. In the embodiment, the sliding mechanism between the pull-out component and the connecting component 200 can also be arranged at the edge of the partition 320, and the baffle 310 is provided with an avoiding slot for avoiding the sliding mechanism.

[0035] In some embodiments of the utility model, the partition 320 is provided with multiple air permeable through holes 321. By arranging the air permeable through holes 321, the air flow in the containing cavity is more smooth, the temperature difference between different positions in the containing cavity is reduced, and the temperature difference between different positions is avoided to be too large to cause inaccurate test results.

[0036] In some embodiments of the utility model, the jig includes a placing seat 331 for placing the battery and a quick clamp 332 for fixing the battery, and the quick clamp 332 is arranged on the left side or the right side of the placing seat 331.
