[0040] Another core of this application is to provide a vehicle lamp with the above-mentioned bracket sub-assembly.

[0041] Another core of this application is to provide a vehicle with the above-mentioned vehicle lamp.

[0042] 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.

[0043] Generally, the light guide bar in a vehicle lamp is fixed by arranging mounting legs on the light guide bar and connecting the mounting legs to the light guide bar bracket or the lamp housing with fasteners such as screws. However, when the light beam emitted by the light source propagates to the position of the mounting leg through the light guide bar, light refraction is likely to occur at the root of the mounting leg, resulting in relatively large light efficiency loss.

[0044] For this reason, as Figure 1As shown, an embodiment of the present application discloses a bracket subassembly for a vehicle lamp, including a light guide bar 100, a bracket 200, a first clamping member 300, and a second clamping member 400. By using the first clamping member 300 and the second clamping member 400 to fix the head light guide portion 101, the middle light guide portion 102, and the tail light guide portion 103 of the light guide bar 100 respectively, there is no need to provide mounting legs on the light guide bar 100, which can avoid the refraction of the light beam emitted by the light source at the root of the mounting legs. At the same time, the annular accommodation cavity 301 of the first clamping member 300 can play an effect of preventing light leakage, so that while the installation of the light guide bar 100 is convenient, the light efficiency loss can be effectively reduced.

[0045] The following will combine Figures 1 to 10 to specifically explain and illustrate the bracket subassembly for a vehicle lamp disclosed in the embodiment of the present application.

[0046] Among them, as Figure 2 shown, the light guide bar 100 can be prepared from polycarbonate (PC) material or polymethyl methacrylate (PMMA) material, so that the light guide bar 100 can have a certain bending ability to flexibly adjust the light transmission path in various application scenarios to meet different lighting requirements. For the convenience of understanding, the regions at both ends of the light guide bar 100 are respectively defined as the head light guide portion 101 and the tail light guide portion 103, and the middle region of the light guide bar 100, that is, the region of the light guide bar 100 except the end regions, is defined as the middle light guide portion 102. At the same time, as Figure 3 shown, an annular groove 201 is formed on the bracket 200 so that the light guide bar 100 can be bent and installed in the annular groove 201, and a port 203 is provided on the bracket 200. When the head light guide portion 101 or the tail light guide portion 103 of the light guide bar 100 extends into the bracket 200 through the port 203 and is bent along the annular groove 201 and then extends out through the port 203 of the bracket 200, it is ensured that both the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 extend out of the port 203 of the bracket 200 to improve the lighting effect, as Figure 1 shown.

[0047] In order to fix both ends of the light guide bar 100 and prevent both ends of the light guide bar 100 from slipping out of the port 203 of the bracket 200, as Figure 1 shown, the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 can be fixed by the first clamping member 300. Specifically, as Figure 4As shown in the figure, the first card member 300 has an annular accommodation cavity 301 that can respectively accommodate the head light guide portion 101 and the tail light guide portion 103. For the convenience of understanding, the annular accommodation cavity 301 for accommodating the head light guide portion 101 is defined as the first annular accommodation cavity, and the annular accommodation cavity 301 for accommodating the tail light guide portion 103 is defined as the second annular accommodation cavity. Moreover, the inner diameter of the first annular accommodation cavity is slightly smaller than the diameter of the head light guide portion 101 of the light guide bar 100, and at the same time, the inner diameter of the second annular accommodation cavity is slightly smaller than the diameter of the tail light guide portion 103 of the light guide bar 100, so that the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 can be in interference fit with the first annular accommodation cavity and the second annular accommodation cavity respectively, thereby preventing the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 from detaching from the first card member 300. In addition, by installing the head light guide portion 101 in the first annular accommodation cavity and installing the tail light guide portion 103 in the second annular accommodation cavity, the effect of preventing light leakage of the light guide bar 100 can be achieved. Also, the first card member 300 can be fixedly connected to the bracket 200 by fasteners. Of course, the first card member 300 and the bracket 200 can also be fixed by plug-in fit or snap-fit, so as to fix the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 on the bracket 200, thereby fixing both ends of the light guide bar 100 and preventing both ends of the light guide bar 100 from protruding out of the port 203 of the bracket 200.

[0048] In order to fix the middle region of the light guide bar 100 and prevent the middle region of the light guide bar 100 from protruding out of the annular groove 201 of the bracket 200, as Figure 1 shown, the middle light guide portion 102 of the light guide bar 100 can be fixed in the annular groove 201 of the bracket 200 through the second card member 400. Among them, the second card member 400 can be a U-shaped buckle or a clamp, etc., and the second card member 400 can be fixed in the annular groove 201 of the bracket 200 by fasteners. Of course, the second card member 400 can also be snap-fitted or plug-in-fitted into the annular groove 201 of the bracket 200.

[0049] It can be seen from the above embodiments that by respectively fixing the head light guide portion 101, the middle light guide portion 102, and the tail light guide portion 103 of the light guide bar 100 through the first card member 300 and the second card member 400, there is no need to provide installation legs on the light guide bar 100, which can avoid the refraction of the light beam emitted by the light source at the root of the installation legs. At the same time, the annular accommodation cavity 301 of the first card member 300 can achieve the effect of preventing light leakage, thereby reducing the light efficiency loss while realizing the convenient installation of the light guide bar 100.

[0050] To facilitate the installation of the first card member 300 and the light guide bar 100, as Figure 4 and Figure 5As shown, in some embodiments, the first card member 300 includes a first fastening member 302 and a second fastening member 303. The second fastening member 303 can be flipped along one side of the first fastening member 302 and cover the first fastening member 302. At the same time, the first fastening member 302 and the second fastening member 303 are locked by a locking mechanism. Two first arc-shaped grooves are symmetrically arranged on the first fastening member 302. At the same time, two second arc-shaped grooves corresponding to the first arc-shaped grooves of the first fastening member 302 are arranged on the second fastening member 303. When the second fastening member 303 covers the first fastening member 302, the first arc-shaped grooves of the first fastening member 302 and the second arc-shaped grooves of the second fastening member 303 enclose an annular accommodating cavity 301. When installing the first card member 300 and the light guide bar 100, as Figure 5 shown, flip the second fastening member 303 outward along one side of the first fastening member 302, that is, flip the second fastening member 303 in a direction away from the first fastening member 302. At this time, the head light guide part 101 and the tail light guide part 103 of the light guide bar 100 can be respectively placed in the two first arc-shaped grooves, and then flip the second fastening member 303 inward along one side of the first fastening member 302, that is, flip the second fastening member 303 in a direction close to the first fastening member 302 until the second fastening member 303 covers the first fastening member 302. At the same time, the first fastening member 302 and the second fastening member 303 are locked by a locking mechanism, so that the installation of the first card member 300 and the light guide bar 100 can be realized, as Figure 6 shown. It can be seen from the above example that by adopting a split structure for the first card member 300, the convenience of installing the first card member 300 and the light guide bar 100 is improved. It should be noted that the first fastening member 302 and the second fastening member 303 can also be independent split parts. When assembling the second fastening member 303 and the first fastening member 302, the second fastening member 303 can be covered on the first fastening member 302 in a direction perpendicular to the first fastening member 302 and locked by a locking mechanism.

[0051] In order to fix the first card member 300 and the bracket 200, as Figure 5 and Figure 7As shown, in some embodiments, the first fastening member 302 is provided with a plugging portion 3021, and a plugging space 3022 is formed between the plugging portion 3021 and the first fastening member 302. When installing the first card member 300 and the bracket 200, the side wall of the port 203 of the bracket 200 can be inserted into the plugging space 3022 to achieve the quick installation of the first card member 300 and the bracket 200. Specifically, the plugging portion 3021 can adopt an L-shaped structure, and one end of the plugging portion 3021 is connected to the first fastening member 302, and a plugging space 3022 is formed between the other end of the plugging portion 3021 and the outer surface of the first fastening member 302. Of course, in order to ensure the reliability of the connection between the first card member 300 and the bracket 200, at least two plugging portions 3021 can be adopted. When there are two plugging portions 3021, the two plugging portions 3021 are respectively located at the corresponding positions of the two first arc-shaped grooves, and plugging spaces 3022 are respectively formed between the two plugging portions 3021 and the outer surface of the first fastening member 302, which improves the reliability of the connection between the first card member 300 and the bracket 200 while ensuring the evenness of force. It should be noted that the number of plugging portions 3021 can be two or more, such as three, four, etc.

[0052] In the above embodiments, a jack cooperating with the plugging portion 3021 can also be provided on the bracket 200. When installing the first card member 300 and the bracket 200, the plugging portion 3021 of the first card member 300 can be inserted into the jack of the bracket 200. Of course, the number of jacks can be the same as the number of plugging portions 3021, or the number of jacks can be more than the number of plugging portions 3021, so as to facilitate the adjustment of the position of the first card member 300.

[0053] In some embodiments, the locking mechanism may include a protrusion provided on the first fastening member 302 and a mouth portion provided on the second fastening member 303, and a guiding inclined surface is provided on the protrusion. When the second fastening member 303 is covered on the first fastening member 302, at this time, the mouth portion of the second fastening member 303 can slide along the guiding inclined surface of the protrusion on the first fastening member 302 until the mouth portion of the second fastening member 303 is sleeved outside the protrusion on the first fastening member 302, thereby locking the second fastening member 303 and the first fastening member 302, and the separation of the second fastening member 303 and the first fastening member 302 can be avoided. When it is necessary to open the second fastening member 303 and the first fastening member 302, only slightly move the mouth portion of the second fastening member 303 away from the protrusion of the first fastening member 302 with a little force, and the second fastening member 303 can be separated from the first fastening member 302. From the above example, it can be seen that through the cooperation of the protrusion on the first fastening member 302 and the mouth portion provided on the second fastening member 303, the first fastening member 302 and the second fastening member 303 can be quickly locked and separated, thereby improving the assembly efficiency of the first card member 300 and the light guide bar 100. It should be noted that the locking mechanism can also adopt the cooperation of bolts and threaded holes to achieve the convenience of locking and separating the first fastening member 302 and the second fastening member 303.

[0054] It should be noted that, in order to prevent the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 from disengaging from the first card member 300, as Figure 2 shown, protruding portions 104 extending outward may be provided on the end faces of the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100, and shallow grooves 3023 cooperating with the protruding portions 104 are provided on the end face of the first fastening member 302, as Figure 4 shown. When the light guide bar 100 and the first card member 300 are installed, the protruding portions 104 on the end faces of the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 are located in the shallow grooves 3023 on the end face of the first fastening member 302. At this time, the end faces of the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 are flush with the end face of the first fastening member 302, so that while not affecting the lighting effect, it can effectively prevent the head light guide portion 101 and the tail light guide portion 103 of the light guide bar 100 from disengaging from the first card member 300, ensuring the reliability of the connection between the first card member 300 and the light guide bar 100.

[0055] In order to fix the second card member 400 and the light guide bar 100, as Figure 8 and Figure 9As shown, in some embodiments, the second card member 400 has an annular receiving groove 401 for receiving the light guide bar 100, and the opening width of the annular receiving groove 401 is smaller than the diameter of the light guide bar 100 to prevent the light guide bar 100 from disengaging from the annular receiving groove 401. When installing the middle light guide portion 102 of the second card member 400 and the light guide bar 100, the annular receiving groove 401 of the second card member 400 can be passed through the head light guide portion 101 or the tail light guide portion 103 of the light guide bar 100 until the second card member 400 is moved to a suitable position and fixed in the annular groove 201 of the bracket 200, thereby realizing the installation and fixation of the second card member 400 and the light guide bar 100.

[0056] To facilitate the installation of the light guide bar 100 and the second card member 400, as Figure 8 and Figure 9 shown, in some embodiments, elastic claws 402 that can open a preset angle are provided on both sides of the opening of the annular receiving groove 401. When installing the middle light guide portion 102 of the second card member 400 and the light guide bar 100, the middle light guide portion 102 of the light guide bar 100 can be squeezed into the annular receiving groove 401 from the opening position of the annular receiving groove 401. At this time, the elastic claws 402 on both sides of the opening can open a certain angle until the middle light guide portion 102 of the light guide bar 100 enters the annular receiving groove 401. At the same time, the elastic claws 402 return to the initial state under the action of elastic force, so that the middle light guide portion 102 of the light guide bar 100 cannot disengage from the opening position of the annular receiving groove 401, thereby realizing the installation of the light guide bar 100 and the second card member 400. From the above examples, it can be seen that by providing elastic claws 402 that can elastically deform on both sides of the opening of the annular receiving groove 401, the middle light guide portion 102 of the light guide bar 100 can be conveniently installed in the annular receiving groove 401 of the second card member 400, improving the installation efficiency of the light guide bar 100 and the second card member 400.

[0057] To realize the connection and fixation of the second card member 400 and the bracket 200, as Figure 3 and Figure 8 shown, in some embodiments, a bayonet 202 is provided in the annular groove 201 of the bracket 200. At the same time, an elastic leg 403 is provided on the second card member 400, and a clamping portion 4031 that cooperates with the bayonet 202 is provided on the elastic leg 403. When installing the second card member 400 and the bracket 200, the elastic leg 403 of the second card member 400 is inserted into the bayonet 202, so that the clamping portion 4031 of the elastic leg 403 abuts against the bayonet 202, thereby preventing the second card member 400 from disengaging from the bayonet 202.

[0058] In some embodiments, as Figure 8As shown, two elastic legs 403 can be adopted, and the two elastic legs 403 are distributed along the circumferential direction of the annular groove 201, that is, along the axial direction of the annular receiving groove 401. At the same time, the distance between the two elastic legs 403 is greater than the width of the bayonet 202 along the circumferential direction of the annular groove 201, so as to prevent the elastic legs 403 of the second fastener 400 from disengaging from the bayonet 202. When installing the second fastener 400 and the bracket 200, the two elastic legs 403 of the second fastener 400 can be squeezed towards the center until the two elastic legs 403 are inserted into the bayonet 202. At this time, the elastic legs 403 return to the initial state under the action of elastic force, so that the two elastic legs 403 cannot disengage from the bayonet 202, thus realizing the rapid installation of the second fastener 400 and the bracket 200, as Figure 10 shown. When disassembling the second fastener 400, only need to squeeze the two elastic legs 403 towards the center until the two elastic legs 403 disengage from the bayonet 202. From the above example, it can be seen that by setting two elastic legs 403, the rapid disassembly and assembly of the second fastener 400 and the bracket 200 can be realized, thereby improving the installation efficiency of the light guide bar 100 and the second fastener 400. It should be noted that in order to facilitate the insertion of the elastic legs 403 into the bayonet 202, the clamping portion 4031 of the elastic legs 403 can be provided with an inclined guiding surface to provide a guiding effect when the elastic legs 403 are inserted into the bayonet 202, thereby improving the efficiency of the elastic legs 403 inserted into the bayonet 202.

[0059] In the above embodiment, the second fastener 400 can be made of rubber material or thermoplastic elastomer, etc., so that the second fastener 400 has the performance of being able to return to the initial state after being deformed by an external force. The material of the second fastener 400 is not limited herein.
