DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation methods.

[0023] like Figure 1-Figure 3 As shown, a new type of plug-in and installation structure, which is used on LED headlights, includes a plug connector 1 made of plastic, with an opening at one end of the plug connector 1, and a metal shell 2, with openings at both ends and one end connected to the open end of the plug connector 1; the metal shell 2 is detachably connected to the plug connector 1; at least three longitudinal notches 201 are provided in the body of the metal shell. Specifically, the metal shell 2 and the plug connector 1 are detachably connected by a plurality of screws. Here, the "body of the metal shell" refers to the solid part of the metal shell, not the hollow part inside it. The plastic here should be understood as all materials suitable for making plug connectors except metal materials, such as materials that can be processed and formed by injection molding.

[0024] like Figure 4As shown, the metal shell 2 and the plug connector 1 are both cylindrical and coaxially assembled; a fan assembly 3 is arranged in the metal shell; the fan assembly 3 includes a fan 301 and a fan bracket 302, the fan bracket includes a bracket body 302a, at least two transverse blocks 302b arranged on the side of the bracket body, and a clamping member 302c is arranged at the end of each transverse block; the clamping member 302c is respectively clamped in two of the longitudinal notches and contacts the bottom of the longitudinal notch. That is to say, in the longitudinal notch 201 here, there are at least two clamping members 302c for installing the fan bracket 302, so that the assembly of the fan assembly 3 is completed through a simple structure; two longitudinal notches 201 can be set for installing the clamping member 302c, and at this time, two clamping members 302c are correspondingly arranged on the fan bracket 302, or more than two longitudinal notches 201 can be used to install the clamping member 302c, and the number of the clamping members is also correspondingly more than two.

[0025] like Figure 4 As shown, here, three clips 302c are set on the fan bracket 302 for explanation; specifically, there are four longitudinal notches 201 set in the main body of the metal shell 2, and the longitudinal notches are parallel to the axial direction of the metal shell; there are three transverse blocks 302b, and the clips 302c on the three transverse blocks are respectively clamped in three of the longitudinal notches 201.

[0026] like Figure 5-Figure 6 As shown, the metal shell 2 of this embodiment is not only used to install the fan assembly 3, but also needs to install a part of the heat dissipation part 4 on the LED car light. In order to install the longitudinal left strip 5 and the longitudinal right strip 6 respectively arranged on the two sides of the heat dissipation part, two of the four longitudinal notches 201 have an angle of 180 degrees, and thickened parts 202 are provided at the upper end openings of the two longitudinal notches, and the longitudinal left strip 5 and the longitudinal right strip 6 are respectively installed in the two longitudinal notches with the thickened parts.

[0027] After the fan assembly 3 is installed, the longitudinal right strip 6 abuts against one of the clips 302c to fix the clip 302c; at the same time, the side edges of two heat sinks 401 of the heat dissipation part 4 respectively extend into the other two longitudinal notches 201 (except the two longitudinal notches of the thickened portion at the upper end) and abut against the clip 302c.

[0028] like Figure 7As shown, the fan bracket 302 is provided with two clips 302c as an example for explanation; with this structure, the two clips 302c are respectively installed in the two longitudinal notches 201, which is different from the fan bracket structure with three clips in that there is no clip 302c in the longitudinal notch 201 for installing the longitudinal right strip 6, but because the heat dissipation part 4 needs to be fixed, the longitudinal notches 201 in the main body of the metal shell 2 are still four, of which two longitudinal notches are respectively used to install the longitudinal left strip 5 and the longitudinal right strip 6. In other words, there is no special requirement for the number of clips 302c, and setting more than two can meet the requirements of installing the fan assembly 3.

[0029] like Figure 3-Figure 4 As shown, a circular chuck 7 integrally formed therewith is sleeved radially on the outer wall of the metal shell 2, and a plurality of notches 701 are provided in the edge of the circular chuck so as to adapt to the structure of the original vehicle's headlight installation position when installing the LED headlight; the other end of the longitudinal notch 201 for installing the three clamping parts 302c contacts the surface of the circular chuck.

[0030] like Figure 3-Figure 4 As shown, two mutually symmetrical connecting pieces 101 and two mutually symmetrical supporting pieces 102 are provided on the surface of one end of the plug connector 1 connected to the metal housing 2. The connecting pieces 101 and the supporting pieces 102 are integrally formed with the plug connector 1.

[0031] In order to achieve a detachable connection with the plug connector 1, the end of the metal shell 2 connected to the plug connector 1 is provided with two symmetrical connecting plates 203 respectively connected to the two connecting sheets 101 and two groups of supporting plates 204 respectively abutting against the two supporting sheets. The connecting plates 203 and the supporting plates 204 are integrally formed with the metal shell 2.

[0032] Specifically, the connecting vertical plate 203 includes an outer vertical plate 203a and an inner vertical plate 203b arranged below and offset therefrom; the lower end of the outer vertical plate abuts against the upper end of the connecting plate 101, the inner vertical plate is located on the inner side of the connecting plate and the two are connected by screws.

[0033] A ventilation gap 1a is provided between each connecting piece 101 and the two supporting pieces 102 on both sides thereof, so the plug connector 1 has four ventilation gaps, which is beneficial for the LED car lamp adopting the installation structure of the utility model to have a good heat dissipation effect during use.

[0034] To summarize, more than two longitudinal notches 201 are provided in the metal shell 2, and more than two clips 302c are provided on the fan bracket 302 of the fan assembly 3. During assembly, the clip 302c is inserted into the upper opening of the longitudinal notch 201, and then moved along the longitudinal notch to its bottom so that the clip 302c contacts the bottom of the longitudinal notch. After one end of the heat dissipation part 4 is inserted into the metal shell, the clip 302c is fixed in the longitudinal notch by the structure on the heat dissipation part, thereby realizing the installation of the cooling fan 301. Here, the structures for fixing the three clips 302c are respectively the longitudinal right strip 6 and the two heat sinks 401. Compared with the prior art, the installation structure of the cooling fan of the utility model is simple, easy to install, and saves time and effort.

[0035] In the above description, it should be noted that the terms "installed", "connected", "connected" and other corresponding terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two components; "provided in" should be understood as "installed in, set in", including fixed installation, movable installation and other installation methods.

The preferred embodiments of the utility model are given in the drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms.
