In some alternative embodiments of the present application, only one end of the driving shaft 22 is rotatably connected to the base 1, which means that only one end of the driving shaft 22 is supported on the base 1 and the other end is in a floating state, i.e. the other end is neither in contact with the wall surface of the base 1 nor supported on the base 1 through a bearing. The auxiliary rotating shaft 62 is connected with the base 1 in a rotating manner.

Referring to fig. 1, 2 and 3, in some alternative embodiments of the present application, the drive bevel gear 21 is located in the middle of the drive shaft 22, and both ends of the drive shaft 22 are rotatably connected to the base 1. In such a structural form, both ends of the driving rotating shaft 22 are rotatably connected with the base 1, which is beneficial to improving the mounting stability of the driving bevel gear 21, so that the driving bevel gear 21 stably supports the driven bevel gear 31. On this basis, in some optional embodiments in the present application, the lower side of the driven bevel gear 31 abuts against the upper side of the driving rotation shaft 22. With the structure, the driving rotating shaft 22 supports the driven bevel gear 31 to a certain extent, which is beneficial to improving the mounting stability of the driven bevel gear 31.

Referring to fig. 1, 2 and 3, of course, in some other alternative embodiments of the present application, the active shaft 22 may have only one end rotatably connected to the base 1. According to the structure form, the installation process can be simplified. On the basis, in some optional embodiments in the present application, the driving rotary shaft 22 is located on the side of the driving bevel gear 21 away from the driven bevel gear 31, so that the structure can avoid the interference between the driving rotary shaft 22 and the driven bevel gear 31. Of course, in some other alternative embodiments in the present application, the driving shaft 22 may also be located on the side of the driving bevel gear 21 close to the driven bevel gear 31, and the lower side of the driven bevel gear 31 abuts against the upper side of the driving shaft 22. With the structure, the driving rotating shaft 22 supports the driven bevel gear 31 to a certain extent, which is beneficial to improving the mounting stability of the driven bevel gear 31.

Referring to fig. 1, 2 and 3, it should be explained that the gap between the driven rotating shaft 32 and the base 1 means that the driven rotating shaft 32 is in a floating state relative to the base 1, the driven rotating shaft 32 is not directly connected with the base 1, and the driven rotating shaft 32 is supported only by the driving bevel gear 21 and the radar mounting assembly 4. The driven rotation shaft 32 not being directly connected to the base 1 means that the driven rotation shaft 32 is not in contact with the wall surface of the base 1 to be supported on the base 1, nor is it supported on the base 1 through a bearing. In some optional embodiments of the present application, the driven rotation shaft 32 is located on a side of the driven bevel gear 31 away from the driving bevel gear 21. Due to the structure, the interference between the driven rotating shaft 32 and the driving bevel gear 21 can be avoided, the interference between the radar mounting component 4 and the driving bevel gear 21 can be avoided, and the movement stroke of the radar mounting component 4 can be improved. It should be noted that the fact that the driven rotation shaft 32 is located on the side of the driven bevel gear 31 far away from the driving bevel gear 21 means that the driven bevel gear 31 is located at the extreme end of the driven rotation shaft 32, and the side of the driven bevel gear 31 close to the driving bevel gear 21 does not have a rotation shaft extending in the axial direction of the driven bevel gear 31. The same thing applies to the drive rotation shaft 22 on the side of the drive bevel gear 21 and the auxiliary rotation shaft 62 on the side of the auxiliary bevel gear 61.

The auxiliary rotating shaft 62 is rotatably connected to the base 1, and only one end of the auxiliary rotating shaft may be rotatably connected to the base 1, or both ends of the auxiliary rotating shaft may be rotatably connected to the base 1. In some optional embodiments of the present application, only one end of each of the driving rotation shaft 22 and the auxiliary rotation shaft 62 is rotatably connected to the base 1, the driving rotation shaft 22 is located at one end of the driving bevel gear 21 away from the driven bevel gear 31, and the auxiliary rotation shaft 62 is located at one end of the auxiliary bevel gear 61 away from the driven bevel gear 31. With such a structure, the support stability of the driven bevel gear 31 is strong, and the auxiliary rotating shaft 62 and the driving rotating shaft 22 are not easy to interfere with the driven bevel gear 31.

On this basis, in some optional embodiments in the present application, the number of the guide rails 51 is two, and the two guide rails 51 are symmetrical with respect to the axis center of the driven rotating shaft 32.

Moreover, the first mounting tube 11 can provide a reliable mounting position for the plurality of guide rails 51, which is beneficial to improving the structural stability.

Referring to fig. 1, 2 and 3, in some alternative embodiments of the present application, an end of the radar mounting assembly 4, which is far from the driven bevel gear 31, extends out of the first mounting cylinder 11 in a direction away from the driven bevel gear 31, and an end of the radar mounting assembly 4, which extends out of the first mounting cylinder 11, is used for mounting a radar. With the structure, the position of the radar mounting component 4 for mounting the radar is located outside the first mounting cylinder 11, so that the radar can be mounted without being limited by the inner space of the first mounting cylinder 11.
