[0031] like Figure 1-Figure 7 As shown, an embodiment of the utility model provides a radar trolley, including a rear shell 1, a chassis body 2, a radar 3, a pan-tilt platform 4 and a camera 5. The radar 3 and the pan-tilt platform 4 are installed on the chassis body 2, and the camera 5 is arranged on the pan-tilt platform 4. The bottom of the rear shell 1 is open, and a main control board 9 is arranged in the rear shell 1, and the main control board 9 is connected to the chassis body 2. One side of the bottom of the rear shell 1 is hinged to the chassis body 2, and the other side of the bottom of the rear shell 1 is detachably connected to the chassis body 2; when the other side of the bottom of the rear shell 1 and the chassis body 2 are in a state where they can be separated from each other, one side of the bottom of the rear shell 1 can rotate relative to the chassis body 2. Figure 1 In the embodiment, the rear housing 1 is in a horizontal state relative to the chassis body 2, that is, in a closed state. Figure 2 In the embodiment, the rear shell 1 is flipped to a certain angle relative to the chassis body 2, that is, in an open state. In this state, there is enough space to facilitate upgrading and repairing operations on the main control board 9.

[0032] By arranging the main control board 9 outside the chassis body 2 and inside the rear shell 1, the rear shell 1 can shield the main control board 9 and prevent it from being directly exposed to the outside. At the same time, one side of the rear shell 1 can be rotated relative to the chassis body 2. When upgrading and debugging is required, the rear shell 1 can be rotated to make it open at a larger angle relative to the chassis body 2, thereby providing a wider operating space for the upgrading and debugging operations of the main control board 9 and making the upgrading and debugging more convenient. When the upgrading and debugging is completed, the rear shell 1 is rotated to reset it.

[0033] Furthermore, if Figure 1-Figure 3 As shown, the rear shell 1 includes a top plate 11, a rear plate 12, and two oppositely arranged vertical plates 13. The rear plate 12 is connected to the rear side of the two vertical plates 13, and the top plate 11 is connected to the upper side of the two vertical plates 13. The rear shell 1 can be an integrally formed structure or a plurality of plates spliced ​​together.

The connection by hinge is low in cost and easy to realize rotation connection. Of course, in other embodiments, other hinged structures can be used instead, for example, the matching structure of the shaft and the sleeve is used to replace the rotation function of the hinge.

[0035] Furthermore, if Figure 1 , Figure 7 As shown, at least one folding connection portion 133 is provided on the lower edge of another vertical plate portion 13 of the two vertical plate portions 13, and a folding connection hole 1331 is opened on the folding connection portion 133, and a locking hole 221 is provided at a position corresponding to the folding connection hole 1331 of the chassis main body 2, and a fastener is connected in the folding connection hole 1331 and the locking hole 221 to lock and fix the rear shell 1 and the chassis main body 2, and the fastener can be a connecting piece such as a screw. In this embodiment, the right vertical plate portion is provided with two folded edge connection parts 133, the two folded edge connection parts 133 are arranged one after the other, and each folded edge connection part 133 is provided with a folded edge connection hole 1331. Correspondingly, the chassis body 2 is provided with two locking holes 221 corresponding to the two folded edge connection holes 1331. After the upgrade and maintenance of the main control board 9 is completed, the rear shell 1 is rotated to a horizontal state, and then screws are installed in the locking holes 221 and the folded edge connection holes 1331 and tightened, thereby realizing the locking of the rear shell 1 and the chassis body 2. It should be noted that in other embodiments, a common buckle structure can be used to realize a detachable connection between the other side of the bottom of the rear shell 1 and the chassis body 2, instead of the screw locking connection method in this embodiment.

[0036] Furthermore, if Figure 3-Figure 6 As shown, the radar car also includes a screen bracket 6, which is connected to the rear shell 1 and can rotate relative to the rear shell 1. A touch screen 7 is installed on the screen bracket 6, and the touch screen 7 is fixed to the screen bracket 6 by screws and other connecting parts. The screen bracket 6 is provided with a plurality of angle adjustment holes 622, and the vertical plate portion 13 is provided with angle fixing holes 132 that match the angle adjustment holes 622. By switching different angle adjustment holes 622 and connecting with the angle fixing holes 132, the touch screen 7 can be placed in different tilt angle states. Specifically, by connecting connecting parts such as fixing pins or screws in the angle adjustment holes 622 and the angle fixing holes 132, the angle positioning of the screen bracket 6 is realized, and then the angle positioning of the touch screen 7 is realized. The entire angle adjustment process is simple and convenient.

[0037] Furthermore, if Figure 3-Figure 6 As shown, the screen bracket 6 includes a screen support panel 61 and an angle adjustment plate 62. There are two angle adjustment plates 62, which are arranged opposite to each other on the left and the right.

The touch screen 7 is in a square shape, and fixing holes are arranged at its four corners. The touch screen 7 is fixed flat on the upper surface of the screen support panel 61 by connecting screws or other connecting parts in the fixing holes. When the angle of the angle adjustment plate 62 changes, the touch screen 7 changes with the angle change of the angle adjustment plate 62, thereby realizing the adjustment of the tilt angle of the touch screen 7.

[0038] like Figure 3-Figure 6 As shown, the bottom of the rear side of the angle adjustment plate 62 is provided with a central hole 621 of the rotating shaft rotatably connected to the vertical plate portion 13, and the vertical plate portion 13 is provided with a hinge hole 131 at a position corresponding to the central hole 621 of the rotating shaft, and the angle adjustment hole 622 is provided on the angle adjustment plate 62 and is located in front of the central hole 621 of the rotating shaft. A plurality of angle adjustment holes 622 are arranged in an arc shape relative to the center of the central hole 621 of the rotating shaft. The angle positioning of the angle adjustment plate 62 is achieved by connecting a pin in the hinge hole 131 and the central hole 621 of the rotating shaft. The number of angle adjustment holes 622 determines the different tilt positioning angles that the touch screen 7 can form. Of course, the angle variation range of the touch screen 7 can be set according to actual needs. After determining the angle variation range that the touch screen 7 needs to set, the number of angle adjustment holes 622 can be designed accordingly to meet the requirements of the angle adjustment range. Figure 4 The diagram shows that the touch screen 7 is in a horizontal state relative to the rear housing 1.
