DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.

[0020] like Figure 1-4 As shown, a car rear taillight with good waterproof sealing performance includes a light board 1 and a taillight cover 2 installed on the light board 1. The cross-section of the light board 1 is a T-shaped structure. The taillight cover 2 includes a top cover 201, a bottom cover 202 and a circular convex edge 203. The bottom end of the top cover 201 is connected to the top end of the bottom cover 202, and the circular convex edge 203 is installed on the outer side wall of the bottom cover 202 near the top. The top cover 201, the bottom cover 202 and the circular convex edge 203 are integrally formed to improve the overall structural strength. The cross-section of the top cover 201 is an isosceles trapezoid, so that its side is inclined, so that rainwater is not easy to gather on the top cover 201.

[0021] A groove 3 for inserting the bottom cover 202 is provided on the side of the light board 1 close to the tail light cover 2, and a lamp body 11 is installed at the bottom of the groove 3. The tail light cover 2 covers the lamp body 11 to protect the lamp body 11, and a wire 12 is electrically connected to the lamp body 11. A mounting column 13 for connecting to the car is symmetrically provided on the side of the light board 1 away from the tail light cover 2.

[0022] A circumferentially arranged first sealing strip 4 is installed at the joint between the bottom cover 202 and the groove 3 to ensure the sealing of the joint between the bottom cover 202 and the groove 3. In this embodiment, the first sealing strip 4 is covered and protected by the circular convex edge 203, and a step groove for the circular convex edge 203 to be inserted is circumferentially arranged at the notch of the groove 3, and a circular baffle 5 is installed at the bottom of the step groove. A circular groove for clamping with the circular baffle 5 is opened on the circular convex edge 203, and a circumferentially distributed second sealing strip 6 is installed between the circular baffle 5 and the circular groove, which not only further improves the waterproof sealing effect, but also utilizes the circular groove to facilitate the protection of the second sealing strip 6. In this embodiment, the number of circular baffles 5 is not limited to one, and a multi-stage sealing effect is formed as the number increases.

[0023] A connecting component is installed between the bottom cover 202 and the groove 3. The end of the bottom cover 202 away from the top cover 201 extends toward the inner side of the tail light cover 2, and the extension part is in contact with the bottom of the groove 3. The connecting component includes a plurality of threaded sleeves 7 installed on the side of the bottom cover 202 close to the bottom of the groove 3. In this embodiment, the plurality of threaded sleeves 7 are evenly distributed on the extension part in the circumferential direction. A guide hole for inserting the threaded sleeve 7 is provided at the bottom of the groove 3. An annular groove 8 connected with the guide hole is provided on the side of the lamp board 1 away from the tail light cover 2. A bolt 9 for fixing the position of the threaded sleeve 7 is installed in the annular groove 8. An annular plug 10 is fixedly mounted on the bolt 9. The annular plug 10 is in contact with the bottom of the annular groove 8, and the annular plug 10 covers the guide hole.

[0024] The working principle of the utility model is as follows: the threaded sleeve 7 on the bottom cover 202 is correspondingly plugged into the guide hole on the bottom of the groove 3. At the same time, the bottom cover 202 will dock with the groove 3, the circular convex edge 203 will dock with the step groove, the circular retaining strip 5 will dock with the circular groove, and the bolt 9 will be tightened to make it threadedly connected with the threaded sleeve 7 until the annular seal 10 presses the bottom of the annular groove 8 to complete the installation between the tail light cover 2 and the lamp board 1. After the installation is completed, the second sealing strip 6 between the circular retaining strip 5 and the circular groove can form a first layer of waterproof sealing structure, and the first sealing strip 4 between the bottom cover 202 and the groove 3 can form a second layer of waterproof sealing structure, thereby forming a multi-level waterproof sealing structure between the lamp cover 2 and the lamp board 1, improving the waterproof effect of the rear tail light of the car, the second sealing strip 6 is located in the circular groove to form protection, and the first sealing strip 4 is covered and protected by the circular convex edge 203, so that the first sealing strip 4 and the second sealing strip 6 are not easily eroded by rainwater, effectively extending the service life and improving the waterproof sealing effect of the rear tail light of the car.

[0025] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
