DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the embodiment, Figure 1-8 A sealed and waterproof structure of a vehicle light box is provided, comprising a light box base plate 1, a light box top cover 2 is provided on the light box base plate 1, and a sealing component is provided on the light box base plate 1;

[0028] Among them, the sealing component includes a rubber seal 4 arranged between the light-emitting box bottom plate 1 and the light-emitting box top cover 2, a connecting frame 6 is set on the front of the light-emitting box bottom plate 1 and the light-emitting box top cover 2, a protective shell 3 is set on the outside of the two connecting frames 6, and a wire 5 is set inside the rubber seal 4.

[0029] See also Figure 1-4 The sides opposite to the bottom plate 1 and the top cover 2 of the luminous box are both provided with a connecting groove 8 that matches the width of the rubber seal 4. The interior of the rubber seal 4 is provided with two wire holes 12 that match the size of the wires 5.

[0030] It should be noted that the provision of the wire hole 12 facilitates the wire 5 to pass through the wire hole 12 and connect to the rubber seal 4 .

[0031] See also Figure 4-5The rubber seal 4 is located between the two connecting frames 6. Ultrasonic welding ribs 13 are provided on the bottom plate 1 and the top cover 2 of the light-emitting box. The surface of the rubber seal 4 is provided with serrated patterns corresponding to the ultrasonic welding ribs 13.

[0032] In actual use, the connection between the vehicle light box and the wire 5 is sealed by the rubber seal 4, and the ultrasonic welding rib 13 is inserted into the rubber seal 4 through interference crimping, and the gap is filled by utilizing the elasticity of the rubber, so that the welded light box has excellent waterproof sealing ability.

[0033] See also Figure 5-7 A heat dissipation cavity 10 is provided inside the rubber seal 4, a heat absorption layer 11 is provided on the inner wall of the heat dissipation cavity 10, a heat conducting column 7 is provided on the outside of the rubber seal 4, and a heat dissipation hole 9 is provided on the outside of the rubber seal 4.

[0034] A plurality of heat dissipation holes 9 are provided on one side of the rubber seal 4 , and a plurality of heat-conducting columns 7 are evenly distributed.

[0035] See also Figure 7 One end of the heat-conducting column 7 passes through and extends into the heat dissipation cavity 10 , and the heat-conducting column 7 contacts the heat-absorbing layer 11 , which is a silicone grease layer.

[0036] During actual use, when the automobile light box is in use, the heat generated by it enters the heat dissipation cavity 10 through the heat dissipation holes 9, and the heat is absorbed by the heat-conducting columns 7 and the heat-absorbing layer 11 and conducted to the outside of the rubber seal 4 for discharge, thereby improving the heat dissipation effect of the rubber seal 4.

[0037] The connecting frame 6 is a magnet, and the protective shell 3 is made of metal. The connecting frame 6 and the protective shell 3 are magnetically attracted.

[0038] During actual use, the protective shell 3 can be set outside the rubber seal 4 through the magnetic attraction between the connecting frame 6 and the protective shell 3, which makes it convenient to take and place the protective shell 3 and to protect the rubber seal 4 through the protective shell 3.

[0039] The protective shell 3 is located outside the two connection frames 6 . A plurality of heat conduction holes are provided on the protective shell 3 . The heat conduction holes facilitate the discharge of heat to the outside of the protective shell 3 .

[0040] It should be noted that the provision of the heat-conducting column 7 and the heat-absorbing layer 11 can reduce the situation in which the rubber seal 4 is damaged due to the inability to effectively dissipate the heat inside the automobile light box when it is used for a long time, thereby increasing the service life of the rubber seal 4.

[0041] The working principle of the above embodiment is:

[0042] During the use of the vehicle light box, the rubber seal 4 is placed in the connecting groove 8 opened on the light box bottom plate 1 and the light box top cover 2, and the light box bottom plate 1 and the light box top cover 2 are ultrasonically welded. The rubber seal 4 is connected to the light box bottom plate 1 and the light box top cover 2 by an embedded crimping process, which has excellent sealing performance, eliminates the glue filling and sealing process, and has the advantages of low cost and few processes. The ultrasonic welding ribs 13 are inserted into the rubber seal 4 by interference crimping, and the gap is filled by the elastic properties of the glue, so that the welded automobile light box has excellent waterproof sealing ability. In addition, during the use of the automobile light box, the heat generated by it enters the heat dissipation cavity 10 through the heat dissipation hole 9, and the heat is absorbed and conducted to the outside by the heat conductive column 7 and the heat absorption layer 11 to be discharged, thereby improving the heat dissipation effect of the rubber seal 4, reducing the situation where the rubber seal 4 is damaged due to the inability to effectively dissipate the heat inside the automobile light box when it is used for a long time, and increasing the service life of the rubber seal 4.
