[0029] In order to enable a more clear understanding of the above-mentioned objects, features and advantages of the present application, the following will further describe the solutions of the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other manners different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present application, and not all the embodiments.

[0031] With reference to Figures 1 to 4 The first aspect of the present application provides a vehicle lamp structure, comprising a light source 1, a shell 2 and a light guide 3; the inside of the shell 2 is formed with a receiving cavity 21, and the light source 1 is installed in the receiving cavity 21; the light guide 3 is independently arranged on the outside of the shell 2, the light guide 3 and the light source 1 are oppositely arranged along a first direction a, and the part of the shell 2 between the light source 1 and the light guide 3 is formed with a light-transmitting area 22 which is light-transmitting, and the light emitted by the light source 1 is emitted into the light guide 3 through the light-transmitting area 22.

[0032] Specifically, the shell 2 can be selected as a cuboid shell or a cylindrical shell structure, the inside of the shell 2 is hollow, so that the space inside the shell 2 is used as the receiving cavity 21, and the light source 1 can be connected to the inner wall of the receiving cavity 21 by means of bolts or adhesion, so that the light source 1 is arranged in the receiving cavity 21. The inside of the shell 2 is the receiving cavity 21, and the outside of the shell 2 is the side of the shell 2 which is away from the receiving cavity 21.

[0033] As shown in Figure 1 and Figure 2 The direction opposite to the shell 2 and the light guide 3 is the first direction a, the second direction b can be perpendicular to the first direction a, when the vehicle lamp structure is arranged in a vehicle, the first direction a can be selected as a vertical direction, i.e. the height direction of the vehicle; the length direction of the vehicle body can be selected as the direction in which the front of the vehicle is toward the rear of the vehicle or the direction in which the rear of the vehicle is toward the front of the vehicle, the second direction b is consistent with the length direction of the vehicle body; the third direction c is perpendicular to both the first direction a and the second direction b, i.e. the third direction c is the width direction of the vehicle.

[0034] The above-mentioned shell 2 can be selected to be made of transparent plastic or glass along the side surface between the light source 1 and the light guide 3 in the first direction a, so that the light-transmitting area 22 of the shell 2 is between the light source 1 and the light guide 3, and the light emitted by the light source 1 can only be emitted from the light-transmitting area 22, so that the light emitted by the light source 1 can be emitted into the light guide 3. Of course, the shell 2 can also be made of transparent material as a whole, the side surface of the shell 2 close to the light guide 3 along the first direction a is the light-transmitting area 22, the light source 1 is a lamp panel, and the lamp panel is arranged toward the light-transmitting area 22, so that the light emitted by the light source 1 can pass through the light-transmitting area 22 and be emitted into the light guide 3.

[0035] The light guide 3 can be a plate or a block made of transparent plastic, or can be a plate or a block made of glass. The light guide 3 has a pattern or a slope structure inside, so that the light entering the light guide 3 is reflected and refracted on the pattern or the slope structure, thereby changing the propagation direction of the light entering the light guide 3. The light guide 3 can also be configured to limit the propagation range of the light, so that the light entering the light guide 3 from the light-transmitting area 22 is emitted from the light guide 3 in the first direction a away from the one end of the housing 2.

[0036] When the vehicle lamp structure is used in a vehicle, the first direction a is consistent with the height direction of the vehicle, and the housing 2 is arranged on the upper side or the lower side of the light guide 3 in the vertical direction, so that the light emitted by the light source 1 propagates in the first direction a, and the light emitted by the light source 1 is emitted from the light guide 3 in the second direction b after being refracted in the light guide 3, so that the light propagating in the second direction b can illuminate the space around the front of the vehicle or the space around the rear of the vehicle.

[0037] The light guide 3 is arranged on the outside of the housing 2, so that the shape of the light guide 3 does not affect the shape of the housing 2, that is, when the light guide 3 needs to be increased in size and changed in shape due to design requirements, the shape and size of the housing 2 do not need to be changed along with the light guide 3, as long as the light-transmitting area 22 faces the light guide 3. The light guide 3 can be arranged separately from the housing 2, or can be arranged in abutment with the light-transmitting area 22 on the outer side of the housing 2.

[0038] The light source 1 can be a light source structure in which an LED (Light Emitting Diode) bulb is mounted on a circuit board, the circuit board supplies power to the LED bulb to make the LED bulb light up, or can be an incandescent bulb or other type of bulb, as long as the light source 1 can emit light toward the light-transmitting area 22.

[0039] The vehicle lamp structure provided by the embodiment of the application is used as follows: the light source 1 is mounted in the accommodating cavity 21 inside the housing 2, the housing 2 is mounted at the position for mounting the vehicle lamp on the front or the rear of the vehicle, the light guide 3 is mounted at the position for mounting the vehicle lamp on the front or the rear of the vehicle, and the housing 2 is arranged on the upper side or the lower side of the light guide 3 in the vertical direction.

[0040] The light source 1 emits light in the first direction a toward the light-transmitting area 22, the light propagates in the vertical direction through the light-transmitting area 22 and enters the light guide 3, the light is refracted in the light guide 3 to change the propagation angle, so that the light emitted from the light guide 3 propagates in the horizontal direction toward the direction away from the vehicle, thereby enabling the light emitted from the light guide 3 to illuminate the space around the front of the vehicle or the space around the rear of the vehicle.

[0041] The vehicle lamp structure provided by the application comprises a light source 1, a shell 2 and a light guide 3. The shell 2 is internally formed with a containing cavity 21, and the light source 1 is installed in the containing cavity 21. The light guide 3 is independently arranged outside the shell 2, and the light guide 3 is oppositely arranged with the light source 1 along a first direction a. The part of the shell 2 between the light source 1 and the light guide 3 is formed with a light-transmitting area 22 which is light-transmitting, so that the light emitted by the light source 1 can be emitted into the light guide 3 through the light-transmitting area 22. After the light is emitted into the light guide 3, the light is emitted out of the light guide 3 under the guidance of the light guide 3, so that the light guide 3 has the illumination function due to the increased brightness, so as to illuminate the space around the vehicle and increase the light-emitting area of the vehicle lamp by increasing the volume of the light guide 3 and changing the shape of the light guide 3. The light guide 3 is independently arranged outside the shell 2, so that the shell 2 does not need to be changed with the change of the volume and shape of the light guide 3. The space occupied by the shell 2 and the light source 1 is kept stable while the light-emitting area of the vehicle lamp is increased, so that the space occupied by the overall structure of the vehicle lamp is reduced, and the design of the vehicle lamp is not limited by the large space occupied by the overall vehicle lamp. Moreover, the shell 2 and the light guide 3 are independently arranged, so that the shell 2 and the light guide 3 can be flexibly installed in the vehicle.

[0042] Referring to Figure 1 and Figure 2 In some embodiments, the shell 2 comprises a lampshade 23 and a lower shell 24. One side of the lampshade 23 is recessed to form a mounting groove 25, and the lower shell 24 is connected to the groove opening of the mounting groove 25, so that the lower shell 24 and the lampshade 23 jointly enclose the containing cavity 21. The light source 1 is arranged in the mounting groove 25, and the light-transmitting area 22 is formed on the side wall of the mounting groove 25 which is close to the light guide 3 along the first direction a.

[0043] Specifically, the groove opening of the mounting groove 25 can be provided with a protrusion, and one side surface of the lower shell 24 can be provided with a clamping groove. The protrusion and the clamping groove are connected through clamping, so that the lampshade 23 and the lower shell 24 are connected with each other, and the lower shell 24 covers the groove opening of the mounting groove 25, so that the space inside the mounting groove 25 can form the containing cavity 21. Of course, the lampshade 23 and the lower shell 24 can also be connected with each other by using bolts.

[0044] The light source 1 is arranged in the mounting groove 25. The light source 1 can be connected with the groove bottom of the mounting groove 25 through bonding, or the light source 1 can be connected with the inner wall of the mounting groove 25 through bolts. The mounting groove 25 can extend along a third direction c. The mounting groove 25 can be a through groove along the third direction c, and the mounting groove 25 has two side walls which are opposite along the first direction a. The side wall of the mounting groove 25 which is close to the light guide 3 along the first direction a is transparent to form the light-transmitting area 22. When the light emitted by the light source 1 propagates towards the light guide 3 along the first direction a, the light emitted by the light source 1 can be emitted into the light guide 3 through the light-transmitting area 22.

[0045] The lampshade 23 can be made of transparent plastic or glass, and the mounting groove 25 can be transparent to form a light transmission area 22 on the side wall of the light guide 3 along the first direction a. Alternatively, the mounting groove 25 can be provided with a window on the side wall along the first direction a, and the window can be made of glass or transparent plastic to form a light transmission area 22 on the side wall of the mounting groove 25.

[0046] Referring to Figures 1 to 4 In some embodiments, the light guide 3 has an incident side 31 on one side along the first direction a facing the light transmission area 22, and an emitting side 32 on one side along the second direction b. The incident side 31 is arranged corresponding to the light transmission area 22, and the light guide 3 has a refractive structure 33 inside. The light emitted by the light source 1 enters the light guide 3 through the incident side 31, and the light inside the light guide 3 is emitted from the emitting side 32 after passing through the refractive structure 33. The second direction b intersects the first direction a.

[0047] In this way, the housing 2 can be arranged on one side of the light guide 3 along the first direction a, thereby reducing the space occupied by the vehicle in the second direction b. When the first direction a is vertical, the vehicle has a large space in the horizontal direction for installing the vehicle lamp structure. The light guide 3 and the housing 2 are arranged opposite to each other along the first direction a, which can better utilize the space of the vehicle for installing the vehicle lamp structure, and provide more design margin for the light guide 3 in the second direction b.

[0048] Specifically, the vehicle lamp structure is installed in the vehicle, and the first direction a can be vertical, and the second direction b and the third direction c can be horizontal. The second direction b can be the length direction of the vehicle, and the third direction c can be the width direction of the vehicle. The incident side 31 of the light guide 3 can have the same shape as the light transmission area 22, and the area of the incident side 31 can be equal to or greater than the area of the light transmission area 22, so that the light emitted by the light source 1 through the light transmission area 22 can be incident on the incident side 31.

[0049] The first direction a and the second direction b can be perpendicular to each other, or they can have a predetermined angle therebetween, such as 30° or 60°.

[0050] The light guide 3 can include an inner layer and a surface layer. The inner layer is connected to the surface layer on both sides along the second direction b. The inner layer has a plurality of inclined surfaces formed by etching or a mold during manufacturing, and the inclined surfaces serve as the refractive structure. The surface layer and the inner layer are both made of transparent material. The inclined surfaces are arranged along the first direction a, so that the light is incident on the inner layer from one side along the first direction a, and the light is reflected or refracted on the inclined surfaces to change the propagation direction of the light from the first direction a to the second direction b, and the light is emitted from the emitting side 32 along the second direction b.

[0051] Referring to Figure 3 and Figure 4 As shown in the drawings, in some embodiments, the refractive structure 33 comprises a plurality of inclined surfaces arranged at an angle with the first direction a, so that the light rays propagating along the first direction a are refracted and reflected by the inclined surfaces and then propagate along the second direction b.

[0052] Specifically, the refractive structure 33 can be a continuous sawtooth structure arranged inside the light guide 3, which comprises a plurality of tooth portions arranged along the first direction a, and the two side surfaces of the tooth portion along the first direction a are inclined surfaces. The angle between the inclined surface and the first direction a can be 60°, 45° or 30°, and the angle between the inclined surface and the first direction a is determined according to the angle between the first direction a and the second direction b and the number of tooth portions, as long as the light rays enter the sawtooth structure along the first direction a, and then the light rays are refracted and reflected by the plurality of tooth portions and then exit along the second direction a.

[0053] After the above-mentioned light rays propagate along the first direction a and irradiate on the inclined surface, part of the light rays are reflected and propagate along the second direction b, and the remaining part of the light rays enter the sawtooth structure and are refracted. When the light rays enter the sawtooth structure from the inclined surface on one side of the tooth portion along the first direction a, the light rays are refracted, and when the light rays exit from the inclined surface on the other side, the light rays are refracted again, so that the light rays passing through the tooth portion of the sawtooth structure are deflected towards the propagation direction close to the second direction b. After the light rays pass through a plurality of sawtooth structures, the light rays can propagate along the second direction b and exit from the light exit side 32.

[0054] Of course, the refractive structure 33 can also be a light-transmitting block arranged inside the light guide 3, and a plurality of rhombic cavities are formed inside the light-transmitting block. The plurality of rhombic cavities are arranged along the first direction a and the second direction b and are spaced apart, so that the side wall of the rhombic cavity along the first direction a is an inclined surface. When the light rays enter the rhombic cavity along the first direction a, the light rays are refracted. When the light rays enter the light-transmitting block from the rhombic cavity, the light rays are also refracted. After the light rays pass through the rhombic cavity, the light rays are deflected towards the propagation direction close to the second direction b. Therefore, after the light rays pass through a plurality of rhombic cavities, the light rays can propagate along the second direction b and exit from the light exit side 32.

[0055] The above-mentioned rhombic cavities or sawtooth structures in the refractive structure 33 can be arranged in a certain regular pattern, or the refractive structure 33 can be arranged at a specific position inside the light guide 3, so that the light rays enter the light guide 3 from the light entrance side 31, the light rays are refracted by the refractive structure 33 and then exit from the light exit side 32. The light rays exiting from the light exit side 32 can form a light spot of a specific shape on the ground, so as to improve the display effect of the vehicle lamp structure.

[0056] Referring to Figure 1 and Figure 2As shown, in some embodiments, the light source 1 and the shell 2 extend along a third direction c, and the light-transmitting region 22 extends along the third direction c, so that the projection of the light source 1 along the first direction a is within the light-transmitting region 22, and the projection of the light-transmitting region 22 along the first direction a is within the light-incident side 31; the third direction c is perpendicular to the first direction a and the second direction b.

[0057] In this way, the light-transmitting region 22 corresponds to the light source 1, and the light-incident side 31 corresponds to the light-transmitting region 22, so that all the light emitted by the light source 1 can pass through the light-transmitting region 22, and all the light passing through the light-transmitting region 22 can irradiate onto the light-incident side 31; the light source 1 and the light-incident side 31 extend along the third direction c, so that the light guide 3 can receive more light without increasing the size of the light guide 3 in the first direction a and the second direction b, thereby improving the brightness of the light guide 3 during operation of the vehicle lamp structure, and saving space of the vehicle lamp structure in the first direction a and the second direction b.

[0058] Specifically, the shell 2 can extend along the third direction c, so that the accommodating cavity 21 extends along the third direction c, and the third direction c is consistent with the length direction of the shell 2; the light source 1 can be a circuit board provided with a plurality of LED bulbs, the circuit board extends along the third direction c, the plurality of LED bulbs are arranged along the third direction c, and the light-transmitting region 22 extends along the third direction c, so that the light-transmitting region 22 corresponds to the plurality of LED bulbs, thereby enabling all the light emitted by the plurality of LED bulbs to pass through the light-transmitting region 22 and irradiate onto the light-incident side 31. Of course, the light source 1 can also be a white incandescent bulb or a halogen bulb, and the white incandescent bulb or the halogen bulb extends along the third direction c.

[0059] The size of the light-transmitting region 22 in the third direction c can be greater than or equal to the size of the light source 1, the size of the light-incident side 31 in the third direction c can be greater than or equal to the size of the light-transmitting region 22, the size of the light-transmitting region 22 in the second direction b is greater than or equal to the size of the light source 1, and the size of the light-incident side 31 in the second direction b is greater than or equal to the size of the light source 1.

[0060] In the first direction a, the projection of the light source 1 on the light-incident side 31 is less than or equal to the area of the light-transmitting region 22 on the light-incident side 31, and the projection of the light source 1 is within the projection of the light-transmitting region 22; in the first direction a, the projection area of the light-transmitting region 22 on the light-incident side 31 is less than or equal to the area of the light-incident side 31, and the projection of the light-transmitting region 22 on the light-incident side 31 is within the light-incident side 31; so that all the light emitted by the light source 1 towards the light-transmitting region 22 can pass through the light-transmitting region 22, and the light-incident side 31 can receive all the light passing through the light-transmitting region 22.

[0061] The first direction a is a vertical direction, the second direction b is a length direction of the vehicle, and the third direction c is a width direction of the vehicle. The light source 1 and the light-transmitting area 22 extend along the third direction c, so that the housing 2 uses the space in the width direction of the vehicle to increase the area in which the light source 1 can emit light and the light guide 3 can receive more light.

[0062] Referring to Figure 1 and Figure 2 In some embodiments, a set of texture structures are formed on the light-emitting side 32.

[0063] Specifically, the light-emitting side 32 is provided with conical protrusions as the patterned portions, or is provided with sawtooth-shaped protrusions as the patterned portions, so that the light emitted from the patterned portions can be refracted and scattered. The patterned portions are arranged on the light-emitting side 32 to form vehicle logos, concentric circles, or wavy patterns as the set of texture structures. When the light emitted from the light-emitting side 32 is projected onto the ground or an object, a light spot with the shape of the set of texture structures can be formed on the ground or the object.

[0064] Of course, the set of texture structures can also be formed on the light-emitting side 32 by etching or cutting, so that the light emitted from the light-emitting side 32 can form a light spot with the shape of the set of texture structures on the ground or the object.

[0065] Referring to Figure 1 and Figure 2 In some embodiments, the light guide 3 includes a light-blocking plate 35 and a refractive plate 34. The light-blocking plate 35 and the refractive plate 34 are arranged along the first direction a. The refractive plate 34 is connected to the side of the light-blocking plate 35 close to the housing 2. The refractive plate 34 is transparent to light, and the refractive structure 33 is formed in the refractive plate 34. The light-incident side 31 is formed on the side of the refractive plate 34 facing the light-transmitting area 22 along the first direction a. The light-emitting side 32 is formed on the side of the refractive plate 34 along the second direction b.

[0066] In this way, the refractive plate 34 is arranged on the side of the light-blocking plate 35 close to the housing 2, so that all the light emitted from the light-transmitting area 22 can enter the refractive plate 34. The light-blocking plate 35 can prevent the light from the refractive plate 34 from being arranged away from the housing 2 along the first direction a, thereby preventing light leakage of the light guide 3 and improving the lighting effect of the light guide 3. The light-blocking plate 35 can also clearly define the edges of the refractive plate 34, so that the edges of the light spot formed on the ground or the object by the light emitted from the refractive plate 34 are clear.

[0067] Specifically, the light shielding plate 35 can be selected as a dark plate body, so that the light rays can be absorbed and reflected by the light shielding plate 35 after being irradiated on the light shielding plate 35, avoiding the light rays from the refracting plate 34 to be emitted from the side of the shell 2 away from the first direction a, avoiding the light leakage of the light guide member 3 in the first direction a. The light shielding plate 35 can also clearly define the edge of the refracting plate 34, so that the edge of the light spot formed on the ground or the object by the light rays emitted from the refracting plate 34 is clear.

[0068] The refracting plate 34 described above can be selected to be made of transparent plastic or glass, and the refracting structure 33 is arranged in the refracting plate 34, so that the light rays are refracted after being irradiated into the refracting plate 34, and the light rays irradiated into the refracting plate 34 along the first direction a propagate along the second direction b after being refracted by the refracting structure 33.

[0069] Referring to FIGS. 1 to 3, Figure 1 and Figure 2 In some embodiments, the light source 1 includes an LED module 11 and a light-transmissive uniform light plate 12; the LED module 11 is connected with the inner wall of the accommodating cavity 21, the LED module 11 and the light-transmissive area 22 are oppositely arranged along the first direction a and spaced from each other, and the uniform light plate 12 is arranged between the light-transmissive area 22 and the LED module 11, one side of the uniform light plate 12 along the first direction a is oppositely arranged with the LED module 11, and the other side is oppositely arranged with the light-transmissive area 22, so that the light rays emitted by the LED module 11 pass through the uniform light plate 12 and the light-transmissive area 22 in sequence and are irradiated into the light guide member 3.

[0070] In this way, the LED module 11 can stably emit light rays and is not easy to heat, and the uniform light plate 12 emits light rays after receiving the light rays emitted by the LED module 11, so that the light rays emitted from the uniform light plate 12 towards the light-transmissive area 22 are uniformly distributed, thereby enabling the uniform light plate 12 to homogenize the light rays emitted by the LED module 11.

[0071] Specifically, the LED module 11 is a circuit board and an LED bulb, and the uniform light plate 12 is a plate body structure, which can be selected to be made of transparent plastic or glass, so that the uniform light plate 12 is oppositely arranged with the light-transmissive area 22 along the first direction a, the light rays emitted by the LED module 11 are first irradiated on the uniform light plate 12, so that the brightness of the uniform light plate 12 is improved, then the light rays emitted by the uniform light plate 12 pass through the light-transmissive area 22 and are irradiated on the light guide member 3, the uniform light plate 12 emits light as a whole to improve the uniformity of the light rays irradiated on the light-transmissive area 22, and the light rays emitted by the LED module 11 are avoided from forming bright spots on the light guide member 3 due to concentration.

[0072] The light source 1 described above extends along the third direction c, that is, the circuit board of the LED module 11 extends along the third direction c, and the plurality of LED bulbs are arranged along the third direction c. The brightness of some of the LED bulbs can be greater than that of the remaining LED bulbs, so that the light emitted by the light guide 3 at different positions of the light emitting side 32 has different brightness, thereby forming a light spot with a specific shape when the light guide 3 illuminates the ground around the vehicle. Moreover, the different brightness of the plurality of LED bulbs can cooperate with the set texture structure and the internal refraction structure 33 of the light guide 3 to form a light spot with a set texture and different brightness on the ground or object.

[0073] The light homogenizing plate 12 described above can be arranged apart from the light transmission area 22 and the LED module 11 along the first direction a. Of course, the light homogenizing plate 12 can also be attached to one side of the light transmission area 22 in the accommodating cavity 21 and arranged apart from the light source 1 along the first direction a. Or, the light homogenizing plate 12 is not limited to being attached to the side of the light source 1 facing the light transmission area 22 along the first direction a. As long as the light emitted by the light source 1 can be irradiated to the light transmission area 22 after passing through the light homogenizing plate 12, the light entering the light transmission area 22 can be uniformly distributed.

[0074] Referring to Figure 1 and Figure 2 In some embodiments, the light source 1 further includes a light-transmissive thick-walled member 13 arranged between the LED module 11 and the light homogenizing plate 12. In this way, one end of the thick-walled member 13 is arranged opposite to the LED module 11 along the first direction a, and the other end is arranged opposite to the light homogenizing plate 12 along the first direction a, so that the thick-walled member 13 can guide the light emitted by the LED module 11 to irradiate to the light transmission area 22 through the thick-walled member 13. The light is constrained in the thick-walled member 13 during propagation, thereby reducing the scattering of the light emitted by the LED module 11 during propagation to the light homogenizing plate 12.

[0075] Specifically, the thick-walled member 13 can be a rectangular or cylindrical structure. The thick-walled member 13 is made of transparent plastic or glass and extends along the first direction a, so that one end of the thick-walled member 13 is arranged opposite to the LED module 11 along the first direction a, and the other end is arranged opposite to the light homogenizing plate 12 along the first direction a. The light emitted by the LED module 11 irradiates on the thick-walled member 13, propagates in the interior of the thick-walled member 13, and then exits from the end of the thick-walled member 13 close to the light homogenizing plate 12, so that the light passes through the light transmission area 22.

[0076] Referring to Figure 1 and Figure 2As shown, in some embodiments, the thick-walled member 13 is provided with a plurality of scattering protrusions 131 evenly distributed on the end face of one end of the light mixing plate 12. In this way, light is scattered after passing through the plurality of scattering protrusions 131, improving the uniformity of light passing through the thick-walled member 13, making the light distribution on the light mixing plate 12 uniform, and ultimately improving the uniformity of light passing through the light-transmitting area 22 and irradiating onto the light guide member 3.

[0077] Specifically, the end face of the thick-walled member 13 is provided with a plurality of light-transmitting conical protrusions or cylindrical protrusions as the scattering protrusions 131, and the plurality of conical protrusions or cylindrical protrusions are evenly distributed on the end face of the thick-walled member 13, so that the plurality of conical protrusions or cylindrical protrusions form a diffuse scattering pattern structure, and light is diffusely scattered after passing through the diffuse scattering pattern structure, and the light is uniformly distributed after passing through the diffuse scattering pattern structure.

[0078] The second aspect of the present application provides a vehicle comprising the vehicle lamp structure as described above.

The vehicle lamp structure can be arranged at the front or rear of the vehicle, and can also be arranged at the door as a signal lamp. The light emitted by the light source 1 enters the light guide member 3 after passing through the light-transmitting area 22, and the light guide member 3 emits the light to the outside of the vehicle frame after receiving the light, so that the light guide member 3 plays a lighting role. The first direction a can be selected as the height direction of the vehicle.

[0080] By using the vehicle lamp structure described above in the vehicle, the light guide member 3 and the housing 2 are independent of each other, and changing the volume and shape of the light guide member 3 does not require changing the volume and shape of the housing 2, so that the overall space occupied by the vehicle lamp structure is reduced, and the space on the vehicle frame where the vehicle lamp is installed is sufficient to install vehicle lamp structures of various shapes, avoiding the limitation of the space of the vehicle frame on the design of the vehicle lamp shape.

[0082] The light guide 3 and the shell 2 are installed on the vehicle frame, the light guide 3 is opposite to the shell 2 along the first direction a, the first direction a is the height direction of the vehicle, the LED module 11 emits light rays towards the light transmission area 22, the light rays are uniformly irradiated on the light transmission area 22 after passing through the thick wall piece 13 and the light mixing plate 12 in turn, the light rays received by the light transmission area 22 are irradiated on the light entrance side 31 along the first direction a through the light transmission area 22, the light rays are emitted from the light exit side 32 of the refractive plate 34 along the second direction b after being refracted by the refractive structure in the refractive plate 34, the light shielding plate 35 blocks the light rays from being emitted from the side of the refractive plate 34 away from the shell 2 along the first direction a. The light rays can illuminate the space outside the vehicle after being emitted from the refractive plate 34.
