DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] The directional nouns involved in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the drawings. Unless otherwise clearly specified and limited, the terms "setting", "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0026] like Figure 1 and Figure 3 As shown, the contact-type power-on principle structure of a light bulb comprises a light bulb assembly 100 and a socket assembly 200, wherein the socket assembly 200 is composed of a first connecting part 300 and a second connecting part 400, wherein one end of the first connecting part 300 is adapted to be connected with the light bulb assembly 100; the second connecting part 400 is installed on the outer side wall of the first connecting part 300, and an anti-slip structure 500 is provided between the two; wherein one end of the second connecting part 400 is adapted to be connected with the light bulb assembly 100.

[0027] It can be understood that the bulb assembly 100 and the socket assembly 200 are one of the many components in the headlamp assembly, and the bulb assembly 100 and the socket assembly 200 can be adapted and connected to the front vehicle lamp assembly.

[0028] like Figure 2 As shown, the bulb assembly 100 includes a bulb 110 and a plug-in portion 120, one end of the plug-in portion 120 is connected to the bulb 110, and the other end of the plug-in portion 120 is embedded in the first connection portion 300, and part of the outer wall of the plug-in portion 120 abuts against the second connection portion 400. In this way, a loop is formed between the bulb assembly 100 and the first connection portion 300 and the second connection portion 400, so that the bulb assembly 100 can work normally.

[0029] Optionally, a circuit board 121 is embedded in the plug-in portion 120 , and one end of the circuit board 121 is connected to the bulb 110 , and the other end is provided with a plug contact 130 , which protrudes away from the bulb 110 and is connected to the first connection portion 300 .

[0030] Optionally, the outer side of the circuit board 121 is wrapped with a skin 122, and a plurality of openings are provided on the skin 122. In this way, the skin 122 wrapped on the outer side of the circuit board 121 plays a certain protective role on the circuit board 121. And by providing the openings on the skin 122 for heat dissipation of the circuit board 121, the operating temperature of the circuit board 121 can be effectively reduced, so that the circuit board 121 can operate stably within an appropriate temperature.

[0031] Optionally, a detachable chuck 140 is also installed on the outer side wall of the skin 122. In this way, the bulb assembly 100 can be connected and fixed with other components of the headlamp through the chuck 140.

[0032] like Figure 4 and Figure 5 As shown, a connection groove 310 is defined inside the first connection part 300, and one end of the connection groove 310 is provided with a slot 311 adapted to the bulb assembly 100. In this way, one end of the bulb assembly 100 can be firmly connected to the first connection part 300 through the connection groove 310 and the slot 311 adapted thereto, thereby reducing the displacement or separation of the bulb assembly 100 from the first connection part 300 under the action of external force, thereby improving the structural stability between the two, and also improving the service life of the two.

[0033] like Figure 5 As shown, a stopper 312 is provided on the inner wall of the connection groove 310. Thus, the space in the connection groove 310 is filled by the stopper 312, so as to limit the portion of the bulb assembly 100 embedded in the connection groove 310, and further improve the connection stability between the lamp holder assembly and the first connection portion 300.

[0034] like Figure 4 and Figure 5 As shown, a protective skirt 320 is provided at one end of one of the outer side walls of the first connection part 300 away from the bulb assembly 100, and a wiring groove 321 is provided on one side of the protective skirt 320. In this way, when the first connection part 300 and the second connection part 400 are connected with a hook, the metal parts on the second connection part 400 can be protected to a certain extent by the protective skirt 320; at the same time, the protective skirt 320 also plays a protective role, which can reduce the possibility of direct contact between the staff and the metal parts in the protective skirt 320, thereby preventing the occurrence of safety accidents such as electric shock.

[0035] Preferably, the outer side wall of the first connection part 300 is provided with continuously arranged side grooves 330, which are adaptively connected with one end of the second connection part 400; wherein one end of the side groove 330 is communicated with the protective skirt 320. In this way, when the second connection part 400 and the first connection part 300 are connected to each other, the end of the second connection part 400 facing the first connection part 300 can be embedded in the side groove 330, so that the side groove 330 can wrap the end part of the second connection part 400 therein, so as to improve the tightness of the connection between the second connection part 400 and the first connection part 300. Therefore, the connection strength between the second connection part 400 and the first connection part 300 is effectively improved.

[0036] like Figure 6As shown, the second connection part 400 is provided with a through cavity 401 adapted to be connected with the first connection part 300. In this way, the second connection part 400 is sleeved on the outer wall of the first connection part 300 through the through cavity 401, so that the two become a whole.

[0037] like Figure 6 As shown, an arc plate 410 is provided at one end edge of the through cavity 401, which is adapted to be connected with the side groove 330; and a clip 420 is provided at the other end of the through cavity 401 to abut against the bulb assembly 100. In this way, the arc plate 410 is arranged at the edge of the through cavity 401 in a facing manner, which guides the connection between the second connection part 400 and the first connection part 300, making the connection between the first connection part 300 and the second connection part 400 smoother. In addition, the arc plate 410 also plays a limiting role, so that when the first connection part 300 is connected with the second connection part 400, the end of the arc plate 410 facing the first connection part 300 abuts against the inner side wall of the side groove 330, avoiding the second connection part 400 from being over-embedded to cause damage to the first connection part 300, or the second connection part 400 is not embedded in place to cause poor connection stability between the two. Thus, the overall stability of the first connection part 300 and the second connection part 400 is effectively improved through the cooperation of the side groove 330 and the arc plate 410. There are at least two clips 420 arranged at the other end edge of the through cavity 401, and the distance between the two clips 420 is less than the thickness of the plug-in part 120 of the bulb assembly 100, so that when the bulb assembly 100 is connected to the first connection part 300, the clip 420 can clamp the plug-in part 120, making the connection between the bulb assembly 100 and the first connection part 300 more stable. On the other hand, the clip 420 is made of metal, and the socket assembly 200 can transport the bulb assembly 100 through the clip 420 so that the bulb assembly can operate stably.

[0038] like Figure 6 As shown, a P-shaped connecting plate 430 is provided on the side wall adjacent to the arc-shaped plate 410 of the outer side wall of the second connecting portion 400, and the P-shaped connecting plate 430 extends into the protective skirt plate 320. In this way, a groove 440 for connecting a cable is provided at one end of the P-shaped connecting plate 430, and the P-shaped connecting plate 430 extends into the protective skirt plate 320, and can be protected by the protective skirt plate 320, thereby preventing the P-shaped connecting plate 430 from directly contacting other objects or human bodies.

[0039] like Figure 3 , Figure 4 , Figure 6As shown, the anti-detachment structure 500 is formed by the protrusion 340 provided on the outer wall of the first connection part 300 and the groove body 440 provided on the side wall of the second connection part 400. In this way, through the mutual cooperation between the protrusion 340 and the groove body 440, the connection between the first connection part 300 and the second connection part 400 is made more stable, and it is not easy to be displaced or separated under the action of external force, thereby ensuring the stability of the connection between the two.

[0040] like Figure 7 As shown, a principle structure of contact-type power-on of a light bulb also includes a lamp body 600, a first fixed point 610, a first fixing piece 611, a second fixed point 620, a second fixing piece 621, and a retaining spring 630. One side of the lamp body 600 is provided with a first fixed point 610 and a second fixed point 620 arranged opposite to each other; the first fixed point 610 is installed with a first fixing piece at one end away from the lamp body 600, and the second fixed point 620 is installed with a second fixing piece 621 at one end away from the lamp body 600; one end of the retaining spring 630 is movably connected to the first fixing piece 611 and the first fixed point 610, and the other end is detachably abutted against the second fixing piece 621.

[0041] Optionally, the middle part of the clamping spring 630 protrudes toward the chuck 140 and abuts against the chuck 140. In this way, the bulb assembly 100 and the lamp body 600 can be tightly connected through the cooperation between the clamping spring 630 and the chuck 140.

[0042] For example, this bulb contact-type power-on principle and structural design has been subjected to all-round process production verification, circuit performance verification, and road test verification on PK model headlights and MPV model headlights, and has passed the single-product headlight GB / T 10485 bench vibration test and the whole vehicle GB / T 12678 automobile reliability road test test respectively.

[0043] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
