[0002] The electric car test line is an important facility in the rail transit system for testing and debugging new or repaired electric cars. On the test line, various performance tests can be carried out on the electric cars to ensure that they meet the design specifications and safety standards.

[0003] The dynamic dispatching auxiliary safety protection system of the electric passenger car test line adopts UWB ultra-wideband wireless communication technology. It exchanges data between the base station equipment deployed on the ground and the train's on-board monitoring instrument, on-board intelligent terminal, and the electronic bracelet worn by the driver. Through wireless transmission, real-time data transmission between vehicles and the ground is realized. In addition, 4G or 5G communication technology is used to transmit the on-site images of the test line to the ground remote monitoring management platform through ground monitoring cameras to monitor the dynamic dispatching status of the vehicles on the test line.

[0004] For example, basic on-board detectors are usually directly fixed on the vehicle body or glass, and cannot flexibly adjust their own position and angle. The scope of use is limited, and they do not have the function of convenient disassembly. The basic bolt installation method increases the equipment disassembly and assembly operation time, which has certain limitations. In order to solve the above technical problems, we have designed an on-board monitoring instrument for electric passenger car test lines. Utility Model Content

[0028] See also Figure 4 , Figure 5 and Figure 6 The movable positioning mechanism 9 includes a connecting frame 903 and an arc groove 907. The bottom of the connecting frame 903 is fixedly connected to the top of the mounting bracket 3. The arc groove 907 is opened through the top of the mounting bracket 3.

[0029] See also Figure 4 , Figure 5 and Figure 6 A card plate 901 is movably sleeved at the center of the surface of the connecting frame 903, and auxiliary grooves 902 are provided at the bottom of the front and back surfaces of the card plate 901;

[0032] The central angle of the baffle 904 is an obtuse angle, and the arc groove 907 exists to provide a storage space for the upper end of the baffle 904. The lower end of the baffle 904 passes through the baffle 904 and is located at the bottom of the mounting bracket 3. The baffle 904 is shaped like a trigger, which is convenient for the staff to drive the baffle 904 to rotate;

[0033] The front and rear inner diameters of the card slot 11 are consistent with the front and rear lengths of the top of the card plate 901, and are both greater than the front and rear lengths of the bottom of the card plate 901. This design allows the auxiliary slot 902 to meet the installation space requirements of the connecting frame 903.

[0034] One end of the screw rod 502 located on the auxiliary frame 7 is in close contact with the surface of the movable rod 6, and one end of the screw rod 502 located on the movable rod 6 is in close contact with the surface of the supporting frame 8;

[0035] By providing the suction cup 2, it can be tightly adsorbed and installed on the vehicle glass to stably install the device. By providing the mounting bracket 3, the vehicle-mounted monitor body 4 can be supported and installed. By providing the anti-slip head 501, it is convenient for operators to prevent the driving screw 502 from slipping and rotating.

[0036] By setting the screw rod 502, it can be threadedly connected with the movable rod 6 or the auxiliary frame 7, and then in the installed state, the support frame 8 or the movable rod 6 can be pressed to prevent the support frame 8 or the movable rod 6 from rotating at will;

[0037] By providing the annular sheet 503 and the anti-loosening spring 504, an elastic pressing effect can be achieved. When the screw 502 is installed and pressed, the anti-loosening spring 504 is compressed to provide an elastic supporting force for the anti-slip head 501 and the screw 502, thereby increasing the friction force to be overcome by the anti-slip head 501 and the screw 502 to prevent the anti-slip head 501 and the screw 502 from rotating at will without external force.

[0038] By providing the movable rod 6 and the supporting bracket 8, the vehicle-mounted monitor body 4 can be movably mounted on the auxiliary frame 7 and the movable rod 6 respectively to meet the requirements of changing the position and changing the angle. By providing the card plate 901 and the card slot 11, the vehicle-mounted monitor body 4 can be prevented from moving randomly in the installed state.

[0039] By providing the auxiliary groove 902, it is possible to provide an installation space for the connecting frame 903. By providing the baffle 904, it is possible to prevent the card plate 901 from rotating outward under the action of an external force. By providing the torsion spring 905, it is possible to connect with the baffle 904 and the arc groove 907, thereby providing an elastic supporting force for the baffle 904 to prevent the baffle 904 from rotating at will.

By providing the connecting wire hole 10 , the peripheral cable can pass through the mounting bracket 3 and be connected to the vehicle-mounted monitor body 4 .

[0041] When in use, all components are in the initial installation state, the suction cup 2 is adsorbed and installed on the vehicle glass, and is located on the side of the driving seat, and does not block the driver's driving vision. According to actual needs, the movable rod 6 can be flexibly rotated to adjust the position and height of the mounting bracket 3, and the supporting bracket 8 can be flexibly rotated to make the mounting bracket 3 in a horizontal state. When it is necessary to press and lock, the anti-slip head 501 is rotated to make the screw 502 rotate and screw in, and the movable rod 6 and the supporting bracket 8 are pressed and locked, and the distance between the two adjacent annular pieces 503 is reduced to prevent loosening. The spring 504 is compressed, increasing the friction force that the screw 502 and the anti-slip head 501 need to overcome during rotation, thereby ensuring the position stability of the movable rod 6 and the supporting bracket 8. When the vehicle-mounted monitor body 4 needs to be disassembled for maintenance, the staff will push the lower end of the baffle 904 forward, and under the positioning action of the positioning rod 906, the upper end of the baffle 904 rotates backward, and the torsion spring 905 is tightened. At this time, it can be rotated outward to allow the card plate 901 to rotate around the connecting frame 903, and the card plate 901 is disengaged from the card slot 11. At this time, the vehicle-mounted monitor body 4 can be removed.
