AI Technical Summary
Car head-up displays are easily contaminated by dust and other debris during long-term use, resulting in damage to projection equipment and poor heat dissipation, resulting in rapid aging and damage.
A projection-type vehicle-mounted head-up display is designed, with a horizontal groove and two symmetrically distributed grooves on its main body. A curved plate that is suitable for the horizontal groove and a side plate that is suitable for the groove are fixed on the transparent plate. The transparent plate and the contact part of the transparent plate are equipped with a sealing rubber ring, and the transparent plate is fixed through a mechanical structure of a screw and a round sleeve to prevent dust from entering. At the same time, bumps are fixed at the bottom to increase the body, reduce the contact area between the base and the vehicle, and improve the heat dissipation effect.
Through the protection design of the transparent board, dust and other substances are prevented from entering the projection lens, extending the service life of the equipment; by increasing the base design, the heat dissipation effect is improved, and the equipment will be prevented from rapidly aging and damaged due to overheating.

[0007] Preferably, the limiting member includes a fixed block fixed on the main body, a screw is rotatably connected to the fixed block, and the screw is threadedly connected to the round sleeve, a bent rod is fixed on the round sleeve, and a clamping block is fixed at the end of the bent rod, and a clamping groove adapted to the clamping block is opened on the side panel.
[0008] Preferably, a sliding groove is provided on the main body, and a sliding block slidably connected to the sliding groove is fixed on the circular sleeve.
[0009] Preferably, an end block is fixed to the end of the screw.
[0010] Preferably, a protrusion is fixed to the bottom of the body, and the protrusion is fixed to the car by adhesive.
[0011] Preferably, a sealing rubber ring is provided on the portion of the transparent plate that contacts the body, and the rubber ring prevents dust or liquid from contacting the projection lens of the body.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0013] 1. The present application controls the movement of the circular sleeve by rotating the screw until the block at the end of the bent rod engages with the slot on the side panel, and the transparent plate is fixed to the body as a whole. The transparent plate protects the projection lens on the body, thereby preventing dust and other substances from affecting the projection lens.
[0014] 2. The present application fixes the main body to the car through adhesive through the protrusions at the bottom of the main body. The protrusions can increase the height of the main body, thereby reducing the contact area between the base of the main body and the vehicle. Therefore, when the vehicle is in the sun, the main body can dissipate heat better and will not age and be damaged quickly due to overheating. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0022] The utility model provides a technical solution, please refer to Figure 1-4 :
[0023] A projection type vehicle head-up display comprises a body 1, a transverse groove 2 and two symmetrically distributed grooves 3 are provided on the body 1, a transparent plate 4 is attached to the projection lens of the body 1, a curved plate 5 matching the transverse groove 2 is fixed on the transparent plate 4, a side plate 6 matching the groove 3 is fixed on the transparent plate 4, and a limiting member for limiting the transparent plate 4 is provided on the body 1. A sealing rubber ring is provided on the part where the transparent plate 4 contacts the body 1, and the rubber ring prevents dust or liquid from contacting the projection lens of the body 1. Therefore, the transparent plate 4 can protect the projection lens of the body 1, and prevent dust and other substances from entering the inside of the projection lens through the gap, thereby affecting the normal use of the projection lens. A convex block 16 is fixed to the bottom of the body 1, and the convex block 16 is fixed to the car by adhesive. The convex block 16 can increase the height of the body 1, thereby reducing the contact area between the base of the body 1 and the vehicle, so that when the vehicle is in the sun, the body 1 can dissipate heat better and will not be quickly aged and damaged due to overheating. Example
[0024] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the limiting member includes a fixed block 8 fixed on the body 1, a screw rod 9 is rotatably connected to the fixed block 8, and the screw rod 9 is connected to the round sleeve 12 by threads, an end block 10 is fixed to the end of the screw rod 9, a curved rod 14 is fixed to the round sleeve 12, and a clamping block 15 is fixed to the end of the curved rod 14, and a clamping groove 7 adapted to the clamping block 15 is provided on the side plate 6. A slide groove 11 is provided on the body 1, and a slider 13 slidably connected to the slide groove 11 is fixed to the round sleeve 12. When the slider 13 is slidably connected to the slide groove 11, it is only necessary to rotate the end block 10 to control the movement of the round sleeve 12, so that the curved rod 14 fixed on the round sleeve 12 moves together until the clamping block 15 on the curved rod 14 extends into the clamping groove 7. Thereby, the position of the side plate 6 is fixed, and the position of the transparent plate 4 is also fixed.
[0025] In summary, when installing the head-up display provided in this embodiment, the curved plate 5 on the transparent plate 4 is engaged with the transverse groove 2, and the side plate 6 is engaged with the groove 3. Then, the slider 13 on the circular sleeve 12 can be slidably connected with the slide groove 11 on the main body 1, and the circular sleeve 12 is pushed to move close to the screw 9. The end block 10 is rotated so that the screw 9 controls the movement of the circular sleeve 12 during rotation until the block 15 at the end of the curved rod 14 is engaged with the groove 7 on the side plate 6. At this time, the transparent plate 4 is fixed to the main body 1, and the transparent plate 4 plays a protective effect on the projection lens on the main body 1, thereby preventing dust and other substances from affecting the projection lens.
