Description

Technical Field

[0001] This utility model relates to the field of vehicle HUD technology, and in particular to a display dust cover. Background Technology

[0002] Most modern cars are equipped with HUD (Head-Up Display) devices, located below a recessed area at the front of the dashboard. A translucent glass panel within this recess prevents dust from contaminating the HUD. However, in practice, dust easily accumulates on the glass, affecting the HUD's usability. Furthermore, the recess is typically quite deep, making cleaning difficult. To address this issue, automotive parts manufacturers design matching head-up display protective covers for various car models. These covers are made of rigid plastic and are molded in one piece, fitting the recess perfectly. An optical glass panel is installed at the bottom of the cover. During use, the cover is simply placed inside the HUD recess. With the cover in place, the optical glass is closer to the dashboard surface, reducing cleaning difficulty. However, because the cover is directly placed inside the recess without any securing mechanism, it can easily wobble and make noise while the car is in motion, affecting the driving experience. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a monitor dust cover.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A display dust cover includes a rigid cover body whose shape corresponds to the shape of a HUD recess on a car dashboard. A transparent optical glass is connected to the bottom of the cover body, and a dustproof flange is provided on the top of the cover body. A raised rib is provided on the outer wall of the cover body, and a through hole is formed on the side wall of the cover body corresponding to the position of the raised rib. A slot larger than the through hole is formed on the inner wall of the cover body corresponding to the position of the through hole. A cover plate is fitted into the slot, and a suction cup is connected to the outer wall of the cover plate. When the cover body is fitted into the HUD recess on the car dashboard, the raised rib fits against the inner wall of the recess, and the suction cup is firmly attached to the inner wall of the recess.

[0005] Furthermore, a boss is provided on the outer side of the cover plate, the shape of the boss corresponds to the through hole, the boss is fitted into the through hole, and the suction cup is connected to the boss.

[0006] Furthermore, the suction cup includes a disc body and a rubber head. The disc body is conical, and the rubber head is integrally disposed at the tip of the disc body. A sleeve is provided on the surface of the boss, and the rubber head is embedded in the sleeve.

[0007] The beneficial effects of this utility model are as follows: Traditional protective covers are made of rigid plastic in one piece and can only be installed in the HUD groove. This application improves the cover body by adding ribs to the outer wall of the cover body. The ribs can not only ensure that the cover body is stably installed in the HUD groove, but also leave space between the outer wall of the cover body and the inner wall of the HUD groove to accommodate the suction cup. After the cover body is installed, the cover plate is inserted into the slot and the suction cup is pressed tightly against the inner wall of the HUD groove. The cover plate can press the cover body tightly and can firmly fix the entire cover body, preventing the cover body from shaking and producing abnormal noise during driving.

[0009] Explanation of the attached drawing numbers: 1. Cover body, 11. Dustproof flange, 12. Rib, 13. Through hole, 14. Slot, 2. Optical glass, 3. Cover plate, 31. Boss, 32. Sleeve, 4. Suction cup. Detailed Implementation

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0011] like Figures 1-3As shown, a display dust cover includes a rigid cover 1, the shape of which corresponds to the shape of the HUD recess on a car dashboard. A transparent optical glass 2 is bonded to the bottom of the cover 1. A dustproof flange 11 is provided on the top of the cover 1, the shape of which is adapted to the car dashboard. Raised ribs 12 are provided on both the left and right outer walls of the cover 1, the ribs 12 being closed rings. Through holes 13 are provided on the left and right side walls of the cover 1 corresponding to the positions of the raised ribs 12. A slot 14, larger than the through hole 13, is provided on the inner wall of the cover 1 corresponding to the positions of the through holes 13. Each slot 14 has a cover plate 3 installed in it. The outer side of the cover plate 3 is provided with a boss 31. The shape of the boss 31 corresponds to the shape of the through hole 13. The boss 31 is installed in the through hole 13 and the surface of the boss is connected to a suction cup 4. Specifically, the suction cup 4 includes a disc body and a glue head. The disc body is conical and the glue head is integrally set at the tip of the disc body. The glue head and the disc body are integrally molded with silicone. The surface of the boss 31 is provided with a sleeve 32. The sleeve 32 has a flange at the opening. The glue head is embedded in the sleeve 32. The flange can prevent the glue head from falling out of the sleeve 32.

[0012] In actual use, the cover 1 is first installed in the HUD groove on the car dashboard. The dustproof flange 11 on the top of the cover 1 is adapted to the car dashboard. When the cover 1 is installed in the HUD groove on the car dashboard, the rib 12 fits against the inner wall of the groove. Then, the cover plate 3 is inserted into the slot 14 and pressed tightly, so that the suction cup 4 is attached to the inner wall of the groove. Under the action of the suction cup 4, the cover plate 3 presses the cover 1 tightly in the HUD groove, thus fixing the cover 1. This can effectively prevent the cover 1 from shaking and producing abnormal noise during driving.

[0013] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
