[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Embodiment 1: The specific structure of the utility model is as follows:

[0032] Please refer to the attached Figure 1-4 The utility model discloses a vehicle headlamp with a quick locking structure. The vehicle headlamp is plugged into a vehicle lamp installation position. The vehicle headlamp and the vehicle lamp installation position are fixed by a locking mechanism after being plugged.

[0033] The automobile headlamp comprises a heat dissipation shell 3 , an LED module 2 , a soldering pad 4 and a pin assembly 5 .

[0034] The heat dissipation shell 3 has a thick part, a thin part, a receiving cavity penetrating both ends of the heat dissipation shell 3, and two symmetrical side grooves 32 arranged at the thin part of the heat dissipation shell 3. The two symmetrical side grooves 32 are opposite to each other and a through hole 33 communicating with the receiving cavity is arranged between the two symmetrical side grooves 32. The mouth end of the thick part is provided with a column cavity communicating with the receiving cavity, and the wall of the column cavity has a circle of steps. The heat dissipation shell 3 is an aluminum alloy heat dissipation shell, which has good thermal conductivity and relatively low cost.

[0035] The LED module 2 is installed in the accommodating cavity, and a light source 22 is provided on both sides thereof and the light source 22 is located in the area of ​​the through hole 33. One end of the LED module 2 extends to the column cavity and protrudes a distance. After the LED module 2 is installed, the tail cover 1 covers the port of the detail. The light source 22 is an LED lamp. The LED module 2 includes a PCB substrate 21, and a soft metal layer 23 that wraps the edge of the PCB substrate 21 and has the ability to expand and contract with heat. The soft metal layer 23 can be closely attached to the heat dissipation shell 3 after being expanded by heat. The soft metal layer 23 is made of an aluminum layer of soft material. The aluminum layer expands by heat and contacts the aluminum alloy heat dissipation shell 3, which can better conduct heat.

[0036] The soldering pad 4 is arranged in the column cavity and fixed to the protrusion of the LED module 2, and the soldering pad 4 is electrically connected to the LED module 2; the soldering pad 4 is a circular soldering pad, on which a power supply circuit is arranged, and the power supply circuit is connected to the circuit on the PCB substrate 21, and the PCB substrate 21 is a rectangular substrate, which is vertically connected and fixed to the circular soldering pad.

[0037] The pin assembly 5 is fixed to the step and electrically connected to the pad 4. The pin assembly 5 includes two pins, a circular bracket fixed to the pins, and a circular cover sleeved on the two pins and fixed to the step. The two pins are connected to the pad 4 through a cable. Example

[0038] The following is a structural description of the locking mechanism of the utility model:

[0039] The outer edge of the plug end of the heat dissipation shell 3 of the present invention is provided with a circle of annular groove 31 , and the outer peripheral surface of the plug end edge of the heat dissipation shell 3 is provided with at least one through hole 34 communicating with the annular groove 31 .

[0040] The locking mechanism includes a magnetic ring 6 and a plug assembly 7 .

[0041] The magnetic ring 6 is embedded in the annular groove 31. After the magnetic ring 6 is fixed, an annular groove is reserved. The annular groove is used to orient the socket of the headlight installation position. An annular iron sheet is fixed to the socket end. When the plug assembly 7 of the utility model is inserted into the socket, the annular iron sheet and the magnetic ring 6 are attracted and fixed.

[0042] The plug-in column assembly 7 is arranged at the lamp mounting position, and the plug-in column assembly 7 includes a shell 71, a directional iron column 73, a spring 72 and a blocking ring 74. The shell 71 is fixed at the lamp mounting position, and has a blind cavity pointing to the through hole 34. The first end of the directional iron column 73 has an external convex retaining ring, and the second end is set as a slope. The directional iron column 73 is placed in the blind cavity, and the inclined surface end is set outward. After the column body of the directional iron column 73 is covered with the spring 72, the blind cavity mouth is screwed through the blocking ring 74 to limit the spring 72. One end of the spring 72 abuts the external convex retaining ring, and the directional iron column 73 can pass through the blocking ring 74. The magnetic ring 6 selects a magnetic ring with a magnetic attraction force large enough to magnetically attract the end of the directional iron column 73 into the through hole 34.

[0043] When the plug assembly 7 of the utility model is inserted into the socket, the magnetic ring 6 has a magnetic attraction to the directional iron column 73, and the directional iron column 73 is attracted by the magnetic attraction, and its bevel end enters the through hole 34. A guide groove is provided in the blind cavity, and the directional iron column 73 moves along the guide groove to prevent the bevel end from deflecting. After the bevel end enters the through hole 34, its non-bevel side is stuck in the through hole 34. At this time, the heat dissipation shell 3 cannot be withdrawn, and then the entire front vehicle headlamp is stuck and cannot be rotated or withdrawn. Therefore, the contact is stable and will not be separated from the socket due to vibration.

[0044] When the automobile headlamp fails and needs to be repaired or replaced, the directional iron post 73 needs to be separated from the through hole 34. Therefore, in the design, the directional iron post 73 is directional and movable in the blind cavity, with its inclined surface end facing the pin assembly 5. After the end of the directional iron post 73 enters the through hole 34, part of its inclined surface is left outside the through hole 34. There is a gap at the outer opening of the through hole 34 for a sleeve to enter. The sleeve is a maintenance part. The sleeve pushes the inclined surface of the directional iron post 73 to make the outer end of the directional iron post 73 leave the through hole 34. The automobile headlamp of the utility model can be pulled out.

[0045] The utility model adopts the magnetic attraction of the directional iron column 73 and the magnetic ring 6 to realize the function of fixing the automobile headlamp, and prevents the automobile headlamp from shaking and preventing the automobile headlamp from being separated from the socket, so as to achieve the purpose of stably connecting the automobile headlamp and the socket.

[0046] In addition, the utility model has a compact structure and a small appearance and can be adapted to a variety of vehicle models.

[0047] In summary, the automobile headlamp of the utility model adopts the method of magnetic attraction + bolt buckle to lock the automobile headlamp in the lamp installation position, thereby improving the installation efficiency and further improving the contact stability of the automobile headlamp. The utility model also sets a soft metal layer on the edge of the PCB substrate, and the soft metal layer expands when heated and can be closely attached to the heat dissipation shell, thereby improving the heat conduction effect and thus improving the heat conduction efficiency.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
