The one end border of fixed plate 64 is through bolt fixed connection in the mounting panel 512 that slides that is the level setting, the vertical bending shaping in other end border of fixed plate 64 has fixed plate two 65, fixed plate two 65 are curved platelike structure, fixed plate two 65 laminating and fixed connection in the outer wall of solid fixed ring 62, so that solid fixed ring 62 is through fixed plate one 64 and two 65 fixed connection in the mounting panel 512 that slides, and through fixed plate one 64 and two 65 increase of fixed plate and solid fixed ring 62's area of contact, in order to increase the stability of being connected between mounting panel 512 that slides and the solid fixed ring 62. In addition, the fixing ring 62 can also be directly fixedly connected to the sliding mounting plate 512.

Referring to fig. 8 and 9, the fastening ring 63 is sleeved on the fixing ring 62, a plurality of fastening plates 621 are disposed around the central axis of the fixing ring 62, the fastening plates 621 are fixedly connected to the fixing ring 62, the fastening plates 621 are disposed around the central axis of the fixing ring 62, and the fastening plates 621 are in an arc-shaped plate-shaped structure. The outer wall of the fastening plate 621 or the inner wall of the fastening ring 63 is in a conical surface structure, in this embodiment, the outer wall of the fastening plate 621 is in a conical surface structure, and the fastening plate 621 is inserted between the fastening ring 63 and the fastening elastic ring 61. Wherein, the edge of the upper opening of the fastening ring 63 is chamfered so as to facilitate the insertion of the fastening plate 621.

When installing mounting panel 51, because fastening elastic ring 61 is elastic shrinkage, and the outer wall of mounting plate 621 is the conical surface form structure, under projecting apparatus 1, second installation mechanism 5's effect, can make solid fixed ring 62 and mounting plate 621 have the trend of gliding downwards, because the restriction of fastening ring 63, can make mounting plate 621 buckle towards fastening elastic ring 61, thereby make fastening ring 63 with the relatively inseparable laminating in fastening elastic ring 61 of mounting plate 621, for the installation, and can do the buffering through fastening elastic ring 61, reduce the rigid vibration of installation box 52 and projecting apparatus 1 in the use.

In other embodiments, the fastening ring 63 may also be threaded onto the securing ring 62 to further increase stability in use. Further, the fastener 6 may also be a bolt screwed to the vehicle body to fixedly attach the mounting plate 51 to the vehicle body directly by the fastener 6; the installation pipe can be directly and fixedly connected in the vehicle body, so that the installation pipe can be sleeved with the fastening elastic ring 61, the fixing ring 62 and the fastening ring 63.

The implementation principle of the vehicle-mounted projection system in the embodiment of the application is as follows: when the projection screen is used, the light rays directly irradiating the eyes of a user can be effectively reduced only by projecting the light rays to the projection screen 2 through the projector 1, so that the damage to the eyes of the user is reduced. When the position and the angle of the projection screen 2 need to be adjusted, the angle of the projection screen 2 can be adjusted only by rotating the projection screen 2; in addition, the position of the projection screen 2 can be adjusted through the height adjusting component 31 and the horizontal adjusting component 32 so as to meet the requirements of users; when the position of the projection screen 2 is adjusted, the mounting box 52 can be slid along the mounting plate 51 according to the user's needs, so as to adjust the positions of the mounting box 52 and the projector 1 mounted on the mounting box 52.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
