[0025] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0026] like Figures 1 to 7 As shown, this case provides a waterproof car lamp structure without soldering wires, including a lamp body 1, a mounting cavity 11 is provided at the front end of the lamp body 1, and the mounting cavity 11 is provided with a circuit board 2 and a lens assembly 3 arranged outside the circuit board 2 in sequence from the inside to the outside. In specific implementation, the circuit board 2 is mounted on the bottom of the mounting cavity 11, and the lens assembly 3 is arranged at the upper end of the circuit board 2, that is, the lens assembly 3 is arranged toward the outside of the lamp body 1 to facilitate the light to be transmitted outward. The rear end of the lamp body 1 is detachably connected with a connector 4, and the detachable connection between the connector 4 and the lamp body 1 facilitates the disassembly, assembly and maintenance between the lamp body 1 and the connector 4. The connector 4 includes a pin end 41, and the pin end 41 includes a conductive pin 411. The conductive pin 411 is inserted into the lamp body 1 and connected to the circuit board 2, and the conductive pin 411 is electrically connected to the circuit board 2. It should be noted that in specific implementation, the number of conductive pins 411 in this case is preferably set to three, so that it can be generally installed on most cars on the market. Of course, under the premise of achieving the same function and effect, the number of the conductive needles 411 can be set to two or more than three according to different requirements.

[0027] As described above, in the specific implementation, compared with the prior art, the automobile lamp of this structure provided in the present case does not need to use multiple wires or wire socket welding to realize the electrical connection between the circuit board 3 and the connector 4. It only needs to set a connector 4 with a conductive pin 411, insert the conductive pin 411 into the lamp body 1 and connect it to the circuit board 2 to realize the electrical connection between the two, which greatly reduces the production and assembly process, makes assembly, disassembly and maintenance convenient and quick, saves labor time, and saves production and maintenance costs.

[0028] like Figure 1 , Figure 2 As shown, the circuit board 2 is connected with an adapter board 5, and the conductive pin 411 passes through the circuit board 2 and then passes through the adapter board 5 and is welded to the adapter board 5. In specific implementation, the conductive pin 411 is electrically connected to the adapter board 5 and the circuit board 2, and then connected to the external power supply through the connector 4 to realize the power-on of the automobile lamp in this case. The welding referred to here is the solder connection commonly used in the field to achieve the conductivity between the adapter board 5 and the conductive pin 411. Compared with the prior art, the electrical connection method between the connector 4 and the inside of the automobile lamp set in this case saves the cumbersome process of welding wires in the early stage. When assembling the automobile lamp in this case, it is only necessary to insert the conductive pin 411 of the connector 4 along the lamp body 1 into the circuit board 2 and then pass through the adapter board 5, and then directly weld the adapter board 5. In this way, the welding can be completed by machine automation, and the production assembly efficiency can be improved.

[0029] Specifically, refer to Figure 6 The connector 4 further includes a socket end 42 disposed at the other end of the pin end 41, and the conductive pin 411 penetrates into the socket end 42 and is exposed to facilitate connection to an external power source.

[0030] like Figure 1-Figure 5 As shown, in order to further improve the waterproof effect of the automobile lamp of this case, liquid is prevented from penetrating from the connection between the connector 4 and the lamp body 1, resulting in damage to the circuit board 2, the adapter board 5 and corresponding parts inside the automobile lamp. In this case, a waterproof rubber pad 6 is connected to the pin end 41, and a groove 12 is provided at the rear end of the lamp body 1. The waterproof rubber pad 6 is interference-fitted and arranged in the groove 12. In specific implementation, the waterproof rubber pad 6 can be made of a flexible and waterproof material such as rubber, silicone, polyurethane, etc., which is integrally formed.

[0031] like Figure 1-Figure 3 , Figure 6 As shown, the connector 4 also includes a connecting portion 43 disposed between the pin end 41 and the socket end 42, a first screw hole 431 is provided on the connecting portion 43, and a second screw hole 13 is provided on the lamp body 1. In specific implementation, a screw is used to pass through the first screw hole 431 and then into the second screw hole 13 to realize a detachable connection between the connector 4 and the lamp body 1, further improving the stability of the connection between the two, and the waterproof rubber pad 6 is pressed and arranged between the two. Of course, the detachable connection between the two can also be realized by other means, such as plug-in, snap-in, etc., as long as the stability of the connection between the two can be guaranteed. Relatively speaking, this screw connection method is convenient for disassembly and assembly, has low cost, is conducive to the stability of the connection between the two, and is not easy to affect the power-on of the car lamp.

[0032] like Figure 1-Figure 3 , Figure 4 , 5 As shown, specifically, in this case, through holes 100 for the conductive needle 411 to penetrate are correspondingly opened on the waterproof rubber pad 6, the lamp body 1, the circuit board 2, and the adapter board 5, so that the conductive needle 411 passes through the waterproof rubber pad 6, the lamp body 1, the circuit board 2 in sequence, and then passes through the adapter board 5 and is welded with the adapter board 5. In specific implementation, the through holes 100 on the waterproof rubber pad 6, the lamp body 1, the circuit board 2, and the adapter board 5 are all consistent in size and shape. In order to make the connection of the conductive needle 411 in the through hole 100 more stable, the size of the through hole 100 should be set to match the size of the conductive needle 411, so as to prevent the conductive needle 411 from shaking or loosening in the through hole. There are three conductive needles 411 in this case, and three through holes 100 are correspondingly opened on the waterproof rubber pad 6, the lamp body 1, the circuit board 2, and the adapter board 5, respectively. It should be noted that conductive metal is provided in the through holes 100 of the circuit board 2 and the adapter board 5 to achieve electrical connection between the conductive needle 411 and the circuit board 2 and the adapter board 5 .

[0033] like Figure 1 , Figure 2 As shown, a plurality of LED lamp beads 21 are arranged on the circuit board 2 to provide light sources for the automobile lamp of this embodiment.

[0034] Specifically, Figure 1 , Figure 2 , Figure 7 As shown, the lens assembly 3 includes a fixing seat 31, in which a focusing lens 32 and a reflective cup 33 are installed, and the lens assembly 3 also includes a fixing frame 34 for tightly setting the fixing seat 31 on the lamp body 1. In specific implementation, the fixing frame 34 is fastened to the lamp body 1 by screws to press the fixing seat 31 on the lamp body 1.

[0035] like Figure 1 , Figure 7 As shown, the focusing lens 32 and the reflective cup 33 can be detachably connected to the fixing seat 31, the fixing frame 34 can be detachably connected to the lamp body 1, and the lower end of the lamp body 1 can be detachably connected to the mounting bracket 7. The automobile lamp provided in this case can be detached from each other in its entirety, and the disassembly and assembly of the entire lamp is convenient, so that the parts of the automobile lamp can be quickly replaced and repaired, and at the same time, it is convenient to maintain and reduce the use cost.

[0036] As mentioned above, this case protects a waterproof car lamp structure that does not require welding wires. All technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
