[0032] Please refer to Figure 1 、Figure 2 , Figure 3 and Figure 4 , to solve the problem of poor sealing of mobile test vehicles, the present utility model proposes a mobile test vehicle 1000, comprising:

[0033] A chassis 1, a vehicle body 2 and a seal 3. Clamping grooves 11 are formed on both outer side walls of the chassis 1 arranged oppositely; a first installation cavity 21 is formed by enclosing the vehicle body 2 and the chassis 1, and clamping blocks 22 are formed on both inner side walls of the first installation cavity 21 arranged oppositely. Each clamping block 22 is clamped and limited with the groove wall of a clamping groove 11; a sealing groove 221 is formed on one side of the clamping block 22 facing the bottom wall of the clamping groove 11; the seal 3 abuts against the groove wall of the sealing groove 221.

[0034] In the technical solution of the present utility model, the clamping blocks 22 on the two opposite inner side walls of the vehicle body 2 are simultaneously clamped with the clamping grooves 11 on the two opposite outer side walls of the chassis 1, so that the vehicle body 2 is clamped on the chassis 1, realizing the detachable connection between the vehicle body 2 and the chassis 1, facilitating the replacement of the vehicle body 2; a seal 3 is installed at the connection between the vehicle body 2 and the chassis 1 to seal the gap between the vehicle body 2 and the chassis 1, which can effectively reduce the probability of sediment or water vapor entering the vehicle body 2 through the gap between the vehicle body 2 and the chassis 1 and wearing the test equipment a, improving the sealing performance of the mobile test vehicle 1000.

[0035] In an embodiment of the present utility model, one side of the seal 3 facing away from the bottom wall of the sealing groove 221 is in interference abutment with the bottom wall of the clamping groove 11. The clamping blocks 22 on the two opposite inner side walls of the vehicle body 2 are simultaneously clamped with the clamping grooves 11 on the two opposite outer side walls of the chassis 1, so that the vehicle body 2 is clamped on the chassis 1, realizing the detachable connection between the vehicle body 2 and the chassis 1, facilitating the replacement of the vehicle body 2; a seal 3 is installed at the connection between the vehicle body 2 and the chassis 1 to seal the gap between the vehicle body 2 and the chassis 1, which can effectively reduce the probability of sediment or water vapor entering the vehicle body 2 through the gap between the vehicle body 2 and the chassis 1; the seal 3 is in interference abutment with the groove wall of the clamping groove 11, so that when the vehicle body 2 is installed, the seal 3 is extruded into the sealing groove 221, ensuring that the contact surface between the seal 3 and the groove wall of the sealing groove 221 is tighter; at the same time, through the interference abutment, the pressure between the seal 3 and the groove wall of the sealing groove 221 increases, thereby increasing the friction force between the seal 3 and the groove wall of the sealing groove 221, effectively preventing the seal 3 from moving in the sealing groove 221; considering comprehensively, the interference abutment between the seal 3 and the bottom wall of the clamping groove 11 improves the sealing performance of the mobile test vehicle 1000.

[0036] In an embodiment of the present utility model, pin holes are formed in the groove walls at both ends of each clamping groove 11, and each pin hole is used for inserting a pin b. Before installation, the pin b in the pin hole is pulled out, and the clamping blocks 22 on the opposite inner side walls of the vehicle body 2 and the clamping grooves 11 on the opposite outer side walls of the chassis 1 are clamped simultaneously, so as to clamp the vehicle body 2 on the chassis 1; after the clamping is completed, the pin b is inserted into the pin holes at both ends of the clamping groove 11 to limit the clamping block 22 on the vehicle body 2 in the clamping groove 11, so as to prevent the clamping block 22 from sliding in the clamping groove 11 and driving the sealing member 3 to slide, thereby reducing the sealing performance of the mobile test vehicle 1000.

[0037] The material of the sealing member 3 can be rubber or silica gel. In an embodiment of the present utility model, the material of the sealing member 3 is rubber. The rubber material has better sealing performance and can effectively prevent sediment and water vapor from entering the first installation cavity 21 to wear the test equipment a; the rubber material usually has high wear resistance and can maintain its performance unchanged for a long time, and also has good aging resistance and can resist the influence of sunlight, high temperature, chemicals and other environmental factors; compared with silica gel, the production cost of rubber is usually lower, and the manufacturing and processing are also simpler; therefore, rubber is preferably used as the material of the sealing member 3.

[0038] In an embodiment of the present utility model, the chassis 1 is formed with a second installation cavity 12, and the second installation cavity 12 is used for installing a control system; the chassis 1 is also provided with a maintenance port, and the maintenance port is used for communicating the second installation cavity 12 with the outside. The control system controls the movement of the chassis 1, such as driving, steering and braking, so as to drive the vehicle body 2 and the test equipment a in the vehicle body 2 to move; a maintenance port is opened on the chassis 1, which is convenient for users to maintain the control system and maintain the mobile test vehicle 1000 so that it can move normally.

[0039] In an embodiment of the present utility model, the chassis 1 further includes a maintenance door 13, and the maintenance door 13 is movably connected to the side wall of the second installation cavity 12, and the maintenance door 13 is used for covering the maintenance port. The maintenance door 13 can cover the maintenance port, thereby preventing foreign objects from entering the second installation cavity 12 from the maintenance port to damage or wear the control system and playing a protective role for the control system; at the same time, users can open the maintenance door 13 during maintenance to maintain the control system, which is convenient for users to operate.

[0040] In an embodiment of the present utility model, the mobile test vehicle 1000 further includes an interface board 4, and the interface board 4 is arranged on the outer wall of the vehicle body 2 and is used for electrically connecting with the test equipment a. The interface board 4 is internally connected to the test equipment a, so that when the performance equipment is debugged, the wiring can be started on the interface board 4 without opening the vehicle body 2 for wiring, which simplifies the operation process and is convenient for users to use.

[0041] In an embodiment of the present utility model, the mobile test vehicle 1000 further includes a touch display screen 5. The touch display screen 5 is disposed on the outer wall of the vehicle body 2 and is used for electrically connecting with the test device a. The touch display screen 5 and the test device a are electrically connected through a computer. After the performance device is electrically connected with the test device a, the test device a can measure various data of the performance device, thereby transmitting signals to the computer. The computer displays the data on the touch display screen 5 for the user to collect, which facilitates the use of the user.

[0042] In an embodiment of the present utility model, heat dissipation holes 23 are formed in the side wall of the first installation cavity 21. Since the power of some test devices a is relatively large, the heat dissipated by the test device a installed in the first installation cavity 21 can exchange heat with the outside air through the heat dissipation holes 23 to achieve the purpose of heat dissipation. Therefore, forming heat dissipation holes 23 in the side wall of the first installation cavity 21 helps the mobile test vehicle 1000 to achieve a better heat dissipation effect.

[0043] In an embodiment of the present utility model, the mobile test vehicle 1000 further includes a heat dissipation fan 6. The heat dissipation fan 6 is disposed in the first installation cavity 21 and faces the heat dissipation holes 23. The heat generated by the test device a exchanges heat with the air in the first installation cavity 21, increasing the air temperature in the first installation cavity 21. The heat dissipation fan 6 can increase the speed of air exchange between the air in the first installation cavity 21 and the outside air, thereby quickly reducing the air temperature in the first installation cavity 21, and enabling the mobile test vehicle 1000 to achieve more efficient heat dissipation.
