DETAILED DESCRIPTION

[0022] The technical solutions of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0023] Please refer to Figs. 1-4 The present application comprises:

[0024] A detachable automobile lampshade mounting structure comprises a lampshade body 2 and a support body 1. The lampshade body 2 is installed on one side of the support body 1. The support body 1 comprises a mounting bracket 4 and a locking assembly 3. The mounting bracket 4 is a hollow cuboid structure. The locking assembly 3 is at least two. The locking assembly 3 is installed on two non-adjacent sides of the mounting bracket 4. The lampshade body 2 is provided with a positioning support 22 on two non-adjacent sides. The locking assembly 3 is provided with a claw 5. The claw 5 cooperates with the positioning support 22. In this embodiment, the mounting bracket 4 is a hollow cuboid structure. The mounting bracket 4 is provided with a car lamp. The claw 5 cooperates with the positioning support 22 on the lampshade body 2 to fix the lampshade body 2 on the mounting bracket 4. The mounting bracket 4 is provided with a locking assembly 3 on two non-adjacent sides to further lock the lampshade body 2 on the mounting bracket 4. Here, the mounting bracket 4 can also be a cylinder or other forms of structure. The locking assembly 3 can also be increased accordingly, as long as it can lock the lampshade body 2 on the mounting bracket 4.

[0025] Further specifically, the locking assembly 3 comprises a fixed support 31, a first limiting support 32, a second limiting support 33 and a straight rack 34, the first limiting support 32 and the second limiting support 33 are fixedly installed on the same side of the fixed support 31, and the straight rack 34 penetrates through the inside of the fixed support 31; the first limiting support 32 is provided with at least two, and the inside of each of the first limiting supports 32 is provided with a first gear 35, the second limiting support 33 is provided with at least two, and the inside of each of the second limiting supports 33 is provided with a second gear 36; the straight rack 34 is located between the two first limiting supports 32, the two first limiting supports 32 are located between the two second limiting supports 33, the first gear 35 is engaged with the straight rack 34, and the second gear 36 is engaged with the first gear 35. In this embodiment, the second gear 36 is a sector gear, the axial dimension of the first gear 35 is smaller than the axial dimension of the sector gear, the pawl 5 is arranged on the side of the sector gear without the gear, the positioning support 22 is provided with a locking groove 23 matched with the pawl 5, when the lamp cover body 2 needs to be disassembled, the straight rack 34 is pulled downward to drive the first gear 35 to rotate, so as to drive the second gear 36 to rotate, and then drive the pawl 5 to rotate, when the pawl 5 rotates to a certain angle, the pawl 5 is separated from the locking groove 23 on the positioning support 22, and the disassembly of the lamp cover body 2 is completed. Since the axial dimension of the first gear 35 is smaller than the axial dimension of the sector gear, when the straight rack 34 is pushed and pulled, only a small displacement can make the sector gear drive the pawl 5 to rotate by a large angle, so as to complete the locking and separation of the locking groove 23; here, the locking assembly 3 can not be provided with the first gear 35, but directly engaged with the straight rack 34 and the sector gear, when the straight rack 34 is pulled, the sector gear rotates, so as to drive the pawl 5 to rotate, thereby completing the disassembly and installation of the lamp cover body 2.

[0026] Further specifically, the fixed support 31 is provided with a locking screw 37, the straight rack 34 is provided with a limiting hole, and one end of the locking screw 37 penetrates through the fixed support 31 and matches with the limiting hole. In this embodiment, after the installation of the lamp cover body 2 is completed, the straight rack 34 is fixed at a certain position through the cooperation of the locking screw 37 and the limiting hole, so as to prevent the locking assembly 3 from moving due to external force, causing the pawl 5 to fall off, and thus causing the lamp cover body 2 to separate from the mounting support 4. At the same time, the limiting hole can position the straight rack 34, and determine the working position of the straight rack 34.

[0027] Further, the fixing support 31 is provided with a locking screw 37, one end of the locking screw 37 is arranged to abut against the straight rack 34. In the embodiment, the straight rack 34 can be fixed at a certain position by directly abutting against the locking screw 37, so that the locking assembly 3 is prevented from moving due to external force, the pawl 5 is prevented from falling off, and the lamp cover body 2 is prevented from being separated from the mounting support 4.

[0028] Further, one end of the straight rack 34 is provided with a push piece 341. In the embodiment, the push piece 341 arranged on the straight rack 34 can facilitate the worker to exert force when pulling the straight rack 34. Here, grooves or pull rings can also be arranged on both sides of the straight rack 34.

[0029] Further, the lamp cover body 2 further comprises a guide plate 21, the positioning support 22 is arranged on the guide plate 21, the mounting support 4 is provided with a limiting step 41 and a positioning groove 42 at one end, the positioning support 22 is matched with the positioning groove 42, and the guide plate 21 is matched with the limiting step 41. In the embodiment, the positioning groove 42 and the positioning support 22 are matched, and the guide plate 21 and the limiting step 41 are matched, so that the lamp cover can be more accurately mounted on the mounting support 4, the sealing performance is improved, the positioning support 22 is positioned, and the pawl 5 can be accurately clamped in the locking groove 23.

[0030] Further, the mounting support 4 is provided with a screw hole 43 on the side. In the embodiment, the screw hole is arranged to fix the vehicle lamp in the mounting support 4, and the heat generated by the vehicle lamp can be dissipated in time through the screw hole during long-time use, so that the service life of the lamp cover body 2 is not affected due to high temperature.

[0031] Further, one end of the pawl 5 matched with the positioning support 22 is provided with an elastic pad. In the embodiment, the pawl 5 is made of hard metal, and a great force is generated when the pawl 5 is in contact with the locking groove 23 and is tightened, so that the inside of the locking groove 23 is damaged. The elastic pad arranged at the end of the pawl 5 can effectively prevent the pawl 5 from being in direct contact with the locking groove 23, so that the service life of the pawl 5 and the locking groove 23 is increased.

[0032] The specific installation process of the lamp cover is as follows: first, the straight rack 34 is pulled downward, the fan-shaped gear is driven to rotate, the pawl 5 is rotated, the straight rack 34 is stopped when the distance between the two ends of the pawl 5 is greater than the length of the positioning support 22, the lamp cover body 2 is mounted on the positioning support 22 through the positioning groove 42 and the limiting step 41, the straight rack 34 is pushed after the mounting is completed, the pawl 5 is rotated into the locking groove 23 of the positioning support 22, and the locking screw 37 is locked when the end of the pawl 5 is in contact with the inside of the locking groove 23, so that the installation is completed.

[0033] In summary, the utility model discloses a lampshade body 22 is fixed on the mounting support 44 through locking assembly 33, then the car lamp is fixed in the inside of mounting support 44 through screw, make the personnel directly open locking assembly 33, can reach the purpose of quick disassembly of lampshade body 22, mounting support 44 also has certain protective effect simultaneously, when lampshade body 22 is impacted, mounting support 44 can protect the car lamp in the inside to a certain extent, improve the service life of car lamp.
