[0026] Reference Figures 1 to 8 As shown in the figure, a mounting structure for an automotive display screen is shown, including a base 1 and a mounting plate 2. Mounting through holes are provided in the middle of both the base 1 and the mounting plate 2. On both sides of the mounting through hole of the base 1, mounting recesses 11 are provided opposite to each other. An L-shaped hook 12 extending longitudinally is formed inside the mounting recess 11. On both sides of the mounting through hole of the mounting plate 2, mounting convex strips 21 are provided opposite to each other. On the outer edges of both sides of the mounting convex strip 21, inverted L-shaped hooks 22 that are buckled with the hook 12 extend horizontally

[0027] As shown in the attached drawings, the base 1 is fixed on the car machine, the mounting recesses 11 are fixed on both sides of the mounting through hole of the base, and the mounting plate 2 is fixed on the back of the display screen. The mounting convex strips 21 are fixed on the mounting plate 2 and can also be integrally formed with the mounting convex strips 21. The mounting convex strips 21 correspond to the positions of the mounting recesses 11. Among them, the hook 12 is formed by extending longitudinally from the bottom surface of the mounting recess 11 and forms an L-shaped hook with an upper opening. Correspondingly, the hook 22 is formed by extending horizontally from the outer edges of both sides of the mounting convex strip 21. During installation, hold the display screen by hand and insert the mounting convex strip 21 into the mounting recess 11, and press it from top to bottom to make the hook 22 snap into the hook 12. Since the hook 22 is formed by extending horizontally from the outer edge of the mounting convex strip 21, the hook 22 and the mounting convex strip 21 are an integral structure, with better strength. At the same time, due to the structure of the mounting convex strip 21 being integrally inserted into the mounting recess 11, on the one hand, it plays a role in mounting and positioning. At the same time, the overall thickness of the mounting convex strip 21 can be completely used to allocate the thickness of the hook 22 and the hook 12, ensuring that the hook 12 and the hook 22 have sufficient thickness and strength

[0028] Furthermore, the mounting recess 11 includes an outer side edge 13, and the outer edge of the hook 12 is connected to the outer side edge 13

[0029] As shown in the attached drawings, this integrated design makes the hook 12 connected to the bottom surface and the outer side edge 13 of the mounting recess 11 into one body, leaving only the inner and upper openings, making its overall strength higher

[0030] Further, the upper edge of the hook 22 is longitudinally connected to the mounting plate 2.

[0031] As shown in the attached drawings, this integrated design makes the front surface of the mounting rib 21 and the hook 22 coplanar, and the top surface is also coplanar with the hook 22. The outer side and the lower side of the hook 22 are open for hanging with the supporting hook 12. The hook 22 with this structure is integrated with the mounting rib 21 and the mounting plate 2, greatly enhancing the overall strength of the hook 22.

[0032] Further, a U-shaped groove 14 is formed at the bottom surface of the mounting recess 11, and a cantilevered elastic reverse hook 15 extending upward is formed. A positioning protrusion 16 is provided on the outer surface of the free end of the elastic reverse hook 15, and a positioning groove 23 slidably engaged with the positioning protrusion 16 is provided on the surface of the mounting rib 21.

[0033] As shown in the attached drawings, since the elastic reverse hook 15 is cantilevered, it naturally has a certain elasticity, and the reverse hook direction is upward. During installation, when the display screen is pressed downward, the hook 22 thereon is hung downward on the supporting hook 12. During the downward movement, the elastic reverse hook 15 turns outward, and the positioning protrusion 16 thereon abuts against the surface of the mounting rib 21. After reaching the position, the positioning protrusion 16 falls into the positioning groove 23, achieving the effects of positioning and clamping and preventing the reverse hook from coming off.

[0034] Further, the positioning protrusion 16 and the positioning groove 23 are hemispherical.

[0035] As shown in the attached drawings, the hemispherical positioning protrusion 16 always maintains point contact with the surface of the mounting rib 21 during the relative sliding process, which can avoid jamming and is also easy to slide into the hemispherical positioning groove 23. Moreover, the hemispherical positioning groove 23 has low requirements for the insertion depth and direction of the hemispherical positioning protrusion 16, and stable engagement can be ensured even with cumulative machining errors.

[0036] Further, the elastic reverse hook 15 and the supporting hook 12 are arranged side by side.

[0037] As shown in the attached drawings, there are two upper and lower groups of the hook 21, the supporting hook 12 and the elastic reverse hook 15 on each mounting rib 21 and mounting recess 11, that is, a stable distribution of four groups at the four corners. Each elastic reverse hook 15 is arranged side by side with the corresponding supporting hook 12, making the meshing position of the positioning protrusion 16 and the positioning groove 23 thereon closer to the fastening position of the corresponding supporting hook 12 and the hook 22, enabling each group of elastic meshing positioning and adjacent fastening to interact with each other, making the clamping of the display screen more stable.

[0038] Further, a convex rib 121 is convexly provided on the inner side of the supporting hook 12.

[0039] As shown in the attached drawings, the most preferred form of the convex ribs is two horizontal upper and lower convex ribs 121, which can achieve small-area contact when the supporting hook 12 contacts the hanging hook 22, preventing the clamping of each pair of supporting hooks 12 and hanging hooks 22 from being more stable and reliable when the flatness is poor due to processing errors. The convex ribs 121 can also be provided on the inner surface of the hanging hook 22.

[0040] Further, guiding inclined surfaces are provided on the upper edge of the supporting hook 12 and the lower edge of the hanging hook 22.

[0041] As shown in the attached drawings, when the display screen is hung downward, the guiding inclined surfaces on the hanging hook 22 and the guiding inclined surfaces on the supporting hook 12 are easily contacted and play a role of mutual guiding, making the downward snap connection of the hanging hook 22 easier.

[0042] Further, the installation concave strip 11 and the base 1 are detachably connected, and the cross section of the installation concave strip 11 is L-shaped.

[0043] As shown in the attached drawings, because the supporting hook 12 and the elastic reverse hook 15 may also be damaged after frequent disassembly or violent disassembly, the installation concave strip 11 is detachably connected to the base 1 by bolts or the like. When the supporting hook 12 or the elastic reverse hook 15 is damaged, only the damaged installation concave strip 11 can be replaced, instead of replacing the entire bottom plate 1, which greatly saves the maintenance cost. The installation concave strip 11 includes a bottom edge and an outer edge, forming an L shape. Of course, the groove can also be a U-shaped groove.

[0044] Further, the two installation convex strips 21 are connected by a connecting cross strip 211 up and down to form an installation convex frame, the installation concave strip 11 is connected by connecting cross edges 111 up and down to form an installation concave frame, and at least a receiving cavity for the up and down movement of the installation convex frame is left above the installation concave frame.

[0045] As shown in the attached drawings, the installation convex strips 21 on both sides and the connecting cross strip 211 up and down are connected end to end to form a square installation convex frame, while the installation concave strips 11 on both sides and the connecting cross edges 111 up and down are connected end to end to form a square installation concave frame. The width direction of the installation convex frame is the same as the width direction of the installation concave frame, and the height direction of the installation concave frame is at least higher than the height of one receiving cavity of the installation convex frame, so that the hanging hooks 22 above the installation convex strips 21 on both sides are temporarily inserted into the receiving cavity. During installation, the connecting cross strip 211 above the installation convex frame abuts against the inner side of the connecting cross edge 111 above the receiving cavity, and the outer edge of the inserted and installed convex frame abuts against the bottom surface of the installation concave frame, so that the hanging hooks 22 on both sides are located above the supporting hooks 12 in the receiving cavity, playing a role of overall positioning of the display screen for the operator. Then, pressing downward can make the hanging hook 22 and the supporting hook 12 tightly snap together, and the operation is very convenient and fast.

[0046] In the detailed description of the present utility model, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "front", "rear", etc. is the positional relationship of the operator in the state of using the present utility model. It is only for the convenience of describing the present utility model, rather than indicating or implying that the indicated device or component must have a specific orientation or positional relationship. Therefore, it should not be construed as a limitation to the present utility model. It can be understood that the above embodiments only express the preferred implementation modes of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, the above technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made to the claims and scope of the present utility model shall fall within the scope covered by the claims of the present utility model.
