[0036] Specifically, the energy compartment 201 of the vehicle 200 is part of the energy supply of the vehicle 200, and the energy compartment 201 includes a battery device that can include a plurality of battery monomers. The front compartment assembly 202 can include a front frame, an air conditioner, and the like. The rear drive assembly 203 can include a motor, a shock absorber, and the like. The front compartment assembly 202 and the rear drive assembly 203 are mechanically decoupled from the energy compartment 201, which means that the front compartment assembly 202 and the rear drive assembly 203 are not mechanically connected by fasteners such as bolts, and the front compartment assembly 202 and the rear drive assembly 203 can move relative to the energy compartment 201 under external force.

[0037] The front compartment assembly 202 and the rear drive assembly 203 can be electrically connected to the energy compartment 201 through the test bench, so that the energy compartment 201 can supply power to the front compartment assembly 202 and the rear drive assembly 203. During the test of the vehicle 200, the energy consumption, throttle response time, sensor sensitivity, and light of the vehicle 200 can be tested.

[0038] The support 11 of the bearing device 10 can provide support for the bearing part 12, and the bearing device 10 can be installed on the floor, which can be made of steel plate and the like.

[0040] In summary, in the test bench 100 of the embodiment of the utility model, the front compartment assembly 202 and the rear drive assembly 203 are mechanically decoupled from the energy compartment 201, the bearing part 12 of the bearing device 10 can bear or release the energy compartment 201, and the cooling box 20 is arranged below the bearing part 12, so that the energy compartment 201 can enter the cooling box 20 from the opening 21 of the cooling box 20 when thermal runaway occurs, thereby reducing the further development of thermal runaway, without the need for cooling treatment of the entire vehicle 200, and the test cost of the vehicle 200 is low.

[0042] Specifically, the bearing part 12 can be a plate-like part, and the bearing part 12 is capable of being extended and retracted relative to the support 11, which means that the bearing part 12 is capable of being extended or retracted relative to the edge of the support 11 towards the energy tank 201. The bearing part 12 can be extended and retracted relative to the support 11 under the action of a driving assembly, for example, the support 11 can be provided with a driving assembly, and the driving assembly can include a motor and a gear assembly connected with the motor, and the motor can drive the bearing part 12 to extend and retract relative to the support 11 through the gear assembly.

[0043] When the bearing part 12 is extended relative to the support 11, the bearing part 12 has a larger size for bearing, so as to be capable of bearing the energy tank 201, and when the bearing part 12 is retracted relative to the support 11, the bearing part 12 has a smaller size for bearing, so as to be capable of releasing the energy tank 201.

[0044] In one example, in the case of thermal runaway of the energy tank 201, a case outside the cooling box 20 can be pressed, so as to make the bearing part 12 retract relative to the support 11, so as to release the energy tank 201.

[0045] Therefore, in the above-mentioned embodiments, the bearing part 12 is capable of being extended and retracted relative to the support 11 to bear or release the energy tank 201, so that the bearing part 12 bears or releases the energy tank 201 in a simple and easy-to-implement manner, and this is conducive to reducing the cost of the test bench 100.

[0046] Please refer to Figures 1-2 In some embodiments, the support 11 includes a base 111 and a column 112 connected with the base 111, and the bearing part 12 is arranged on the column 112.

[0049] In some embodiments, the number of the bearing devices 10 is greater than or equal to 3, and all the bearing devices 10 are arranged in a ring shape. For example, all the bearing devices 10 can be arranged in a triangular ring shape, a quadrilateral ring shape, a pentagonal ring shape, etc. In this way, in the above-mentioned embodiments, the number of the bearing devices 10 is conducive to further stably bearing the energy bin 201.

[0051] In some embodiments, the cover 30 comprises a cover film. In the above-mentioned embodiments, when the cover 30 is a cover film, the cover film is easy to deform, so that the energy bin 201 can break the cover film under the action of gravity, thereby smoothly entering the cooling box 20.

[0052] Of course, in other embodiments, the cover 30 can be a plate-like part, and the cover 30 can be rotatably arranged with the cooling box 20. Under the gravity of the energy bin 201, the cover 30 can rotate relative to the cooling box 20, thereby opening the opening 21 of the cooling box 20.
