The focus is adjusted by a lens slider focusing structure and a Z-direction platform structure for alignment, and then a screw is tightened in the Z direction. Among them, the slider focusing structure and the Z-direction platform structure have relatively large relative degrees of freedom in the Y direction and the Z direction. During the process of tightening the Z-direction screw after focusing, the relative position of the lens and the light source may change, resulting in the failure of focus adjustment.

[0036] The core of this application lies in providing an illumination module to improve the stability of focusing.

[0037] Another core of this application lies in providing a vehicle with the above-mentioned illumination module.

[0038] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0039] With the development of vehicle headlight lighting technology, pixel modules have become more and more popular. During the assembly process of pixel modules, due to the stability of pixel module manufacturing processes and the differences in parts, the process of imaging focusing is essential.

[0040] In the traditional pixel module imaging, the focal length adjustment usually fixes the Z direction, and can be arbitrarily adjusted in the X and Y directions, that is, the X and Y directions of the pixel module are completely unrestricted. Focusing is performed by adjusting the focus of the lens slider structure and the Z-direction platform structure, and then locking with screws in the Z direction. Among them, the slider focusing structure and the Z-direction platform structure have relatively large degrees of freedom in the Y and Z directions. During the process of locking the Z-direction screw after focusing, the relative position of the lens and the light source may change, resulting in focusing failure.

[0041] Therefore, as Figure 1 and Figure 2 shown, the embodiments of this application disclose an illumination module, including a lens module 100 and a support platform 200. By sliding the sliding member 101 in sliding cooperation with the sliding groove 201, the displacement in the z and y directions can be restricted, preventing the position of the lens module 100 from changing when the lens module 100 is locked, and improving the stability of focusing. At the same time, the fastener 102 is locked along the direction perpendicular to the side wall of the sliding groove 201. Without considering the y-direction depth problem, the size of the lens module 100 can be reduced. In addition, the locking direction of the fastener 102 is consistent with the process installation direction, which can shorten the production time and improve production efficiency.

[0042] The following will combine Figures 1 to 9 to specifically explain and illustrate the lighting module disclosed in the embodiments of the present application.

[0043] Among them, as Figure 1 shown, at least one of the lens module 100 and the support platform 200 is provided with a slider 101, and the other is provided with a chute 201 that cooperates with the slider 101. Moreover, the chute 201 can extend along a direction parallel to the lens module 100. At the same time, the opening side 2011 of the chute 201 is arranged towards or away from the direction of the lens module 100. Through the sliding cooperation of the slider 101 and the chute 201, the focusing of the lens module 100 is realized. After the focusing of the lens module 100 is completed, it can be locked by a fastener 102 such as a bolt along the direction perpendicular to the side wall of the chute 201. As can be seen from the above embodiments, through the sliding cooperation of the slider 101 and the chute 201, as Figure 2 shown, the displacements in the z-direction and y-direction can be restricted, preventing the position of the lens module 100 from changing when the lens module 100 is locked, and improving the stability of focusing. At the same time, the fastener 102 is locked along the direction perpendicular to the side wall of the chute 201, without considering the y-direction depth problem, and the size of the lens module 100 can be reduced. In addition, the locking direction of the fastener 102 is consistent with the process installation direction, which can shorten the production time and improve the production efficiency.

[0044] In some embodiments, as Figure 8 and Figure 9 shown, the slider 101 can be a rectangular plate strip, and two sliders 101 can be used. The two sliders 101 can be symmetrically arranged on both sides of the lens module 100 or the support platform 200 respectively. At the same time, the chute 201 can adopt a structure in the shape of a capital "J" or a U-shaped structure adapted to the slider 101, so that the cross-sectional shape of the groove body of the chute 201 is in the shape of a capital "J" or a U, so that the groove body of the chute 201 can have a large contact area with the slider 101, ensuring the stability of focusing and the connection strength. And, two waist-shaped holes 1011 are provided on the slider 101, and mounting holes 2012 adapted to the waist-shaped holes 1011 of the slider 101 are respectively provided on the two side walls of the chute 201. After the focusing action of the lens module 100 is realized through the waist-shaped holes 1011, a fastener 102 such as a bolt can pass through the waist-shaped holes 1011 and the mounting holes 2012 to lock the lens module 100 and the support platform 200. Of course, the slider 101 can also adopt a columnar structure, and the chute 201 can adopt a C-shaped structure adapted to the slider 101, so that the groove body of the chute 201 can have a large contact area with the slider 101, ensuring the stability of focusing and the connection strength.

[0045] In some embodiments, as Figures 1 to 4As shown, the slide groove 201 can be arranged on the support platform 200, and the open side 2011 of the slide groove 201 is arranged toward the direction of the lens module 100, that is, the open sides 2011 of the two slide grooves 201 are arranged opposite to each other, and at the same time, the outer end of the slide groove 201, that is, the end close to the lens module 100, is connected with the groove body of the slide groove 201, so that the sliding member 101 slides into the groove body of the slide groove 201 from the outer end of the slide groove 201. At the same time, the sliding member 101 can be arranged on the lens module 100. When installing, the sliding member 101 of the lens module 100 is slid into the groove body of the slide groove 201 through the outer end of the slide groove 201, so that the waist-shaped hole 1011 of the sliding member 101 corresponds to the mounting hole 2012 on the side wall of the slide groove 201, and after adjusting to a suitable position, the lens module 100 and the support platform 200 are locked by fasteners 102 such as bolts passing through the mounting hole 2012 and the waist-shaped hole 1011.

[0046] In some embodiments, Figure 5 and Figure 6 As shown, the slide groove 201 can also be arranged on the lens module 100, and the opening side 2011 of the slide groove 201 is arranged away from the direction of the lens module 100, that is, the opening sides 2011 of the two slide grooves 201 are arranged opposite to each other, and at the same time, the inner end of the slide groove 201, that is, the end close to the support platform 200, is connected with the groove body of the slide groove 201, so that the sliding member 101 slides into the inner end of the slide groove 201. At the same time, the sliding member 101 can be arranged on the support platform 200. When installing, move the inner end of the slide groove 201 of the sliding member 101 closer to the sliding member 101 of the supporting platform 200 until the sliding member 101 enters the groove body of the slide groove 201, so that the waist-shaped hole 1011 of the sliding member 101 corresponds to the installation hole 2012 on the side wall of the slide groove 201. After adjusting to the appropriate position, fasteners 102 such as bolts are passed through the installation hole 2012 and the waist-shaped hole 1011 to achieve locking between the lens module 100 and the supporting platform 200.

[0047] In some embodiments, Figures 1 to 3 As shown, the support platform 200 may include a lens support 202 and a heat sink assembly 203, and one of the sliding member 101 and the slide groove 201 is disposed on the lens support 202.

When installing, the sliding member 101 of the lens module 100 is slid into the groove body of the slide groove 201 through the outer end of the slide groove 201, so that the waist-shaped hole 1011 of the sliding member 101 corresponds to the mounting hole 2012 on the side wall of the slide groove 201, and after adjusting to a suitable position, the lens module 100 and the lens holder 202 are locked by fasteners 102 such as bolts passing through the mounting hole 2012 and the waist-shaped hole 1011. In addition, the lens holder 202 and the heat sink assembly 203 are fixed together by screws, and a thermal insulation gasket 300 and a first seal 400 can be set between the lens holder 202 and the heat sink assembly 203 to achieve a sealing and heat insulation effect. At the same time, the lens module 100 and the lens holder 202 can be sealed by a second seal 500, wherein the first seal 400 and the second seal 500 can be sealed by silicone sealing rings or the like.

[0048] Of course, if Figure 5 and Figure 6 As shown, the slide groove 201 can also be arranged on the lens module 100, and the open side 2011 of the slide groove 201 is arranged away from the lens module 100, that is, the open sides 2011 of the two slide grooves 201 are arranged opposite to each other, and at the same time, the inner end of the slide groove 201, that is, the end close to the lens bracket 202, is connected with the groove body of the slide groove 201, so that the sliding member 101 slides into the inner end of the slide groove 201.

After adjusting to the appropriate position, fasteners 102 such as bolts are passed through the installation hole 2012 and the waist-shaped hole 1011 to achieve locking between the lens module 100 and the lens holder 202.

[0049] In some embodiments, Figure 7As shown, the support platform 200 may also include a radiator assembly 203. One of the sliding member 101 and the sliding groove 201 is disposed on the radiator assembly 203, that is, the lens bracket 202 is not provided, which can reduce the number of parts, and at the same time can reduce the volume of the lighting module and reduce the cost.
