[0002] In recent years, the design trend of passenger cars tends to be simple and round, and the design of tail lamps tends to be slim. In order to make the back door split line more smooth and expand the back door opening, the transverse width of the tail lamp is continuously reduced to adapt to the technical requirements of lightweight, space maximization, etc. The reduction of the width of the tail lamp will reduce the illumination range of the tail lamp, affect the visual effect when the tail lamp emits light, and make other drivers or pedestrians easily ignore the light of the tail lamp and easily cause danger.

DETAILED DESCRIPTION
[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. 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.
[0038] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.
[0039] Reference Figures 1 to 10 As shown in FIG. 1, the embodiment of the present application provides a vehicle tail structure, which comprises a tail light 1, a vehicle tail 2 and a back door 3; the vehicle tail 2 is formed with a trunk 21, the back door 3 is rotationally arranged on the vehicle tail 2, the back door 3 can shield the trunk 21 when closed and can expose the trunk 21 when opened, and the tail light 1 is installed on the vehicle tail 2 and arranged at the side of the trunk 21; the tail light 1 comprises a first light exit surface 11 and a second light exit surface 12, light can be transmitted through the first light exit surface 11 and the second light exit surface 12, the first light exit surface 11 is exposed on the side of the vehicle tail 2 along the longitudinal direction of the vehicle, and the second light exit surface 12 is arranged towards the trunk 21 along the transverse direction of the vehicle; the second light exit surface 12 is covered when the back door 3 is closed and is exposed when the back door 3 is opened.
[0040] Specifically, the vehicle has a vehicle body as a main structure, a longitudinal direction of the vehicle is a direction in which a vehicle head of the vehicle faces a vehicle tail, a lateral direction of the vehicle is a direction in which two rear wheels of the vehicle face each other, an end of the vehicle body at the vehicle tail is the vehicle tail 2, the vehicle tail 2 is provided with a box body structure as a trunk 21, the trunk 21 is a box body with an opening exposed at an end of the vehicle tail 2, and a tailgate 3 is rotationally connected to the vehicle tail 2, the tailgate 3 is in a closed state when being rotated downward to cover the opening of the trunk 21, and the tailgate 3 is in an open state when being rotated upward to expose the opening of the trunk 21.
[0041] In order to reasonably utilize the space of the vehicle tail 2, the tail lamp 1 is arranged at a corner of the vehicle tail 2, so that the first light exit surface 11 is exposed on a surface side of the vehicle tail 2, and the tail lamp 1 extends toward the trunk 21 in the lateral direction of the vehicle to the opening of the trunk 21, so that the second light exit surface 12 is exposed on a side wall of the opening of the trunk 21 in the lateral direction of the vehicle; generally, the area of the tailgate 3 is greater than the opening of the trunk 21, and the vehicle tail frame is recessed to form an adaptive groove on the vehicle tail frame in order to match the tailgate 3, the opening of the trunk 21 is formed on a groove bottom of the adaptive groove, a side wall of the adaptive groove is on a periphery of the opening, and the second light exit surface 12 can also be selected to be exposed on the side wall of the adaptive groove toward the trunk 21 in the lateral direction of the vehicle, so that light can be transmitted to the outside of the vehicle tail 2 through the second light exit surface 12 when the tailgate 3 is opened.
[0042] When the tailgate 3 is closed, the tailgate 3 will block the second light exit surface 12. For example Figure 1 As shown, the tailgate 3 is in a closed state, the tailgate 3 blocks the second light exit surface 12, and light is transmitted to the outside of the vehicle tail 2 through the first light exit surface 11; Figure 2 As shown, the tailgate 3 is in an open state, the second light exit surface 12 is exposed on the vehicle tail 2, and light is transmitted to the outside of the vehicle tail 2 through the first light exit surface 11 and the second light exit surface 12.
[0043] The tail lamp 1 can be selected to include a shell and a light source, the light source is in the shell, two faces of the shell are respectively the first light emitting surface 11 and the second light emitting surface 12, the first light emitting surface 11 and the second light emitting surface 12 are transparent structures, so that the light can pass through the first light emitting surface 11 and the second light emitting surface 12. Of course, the tail lamp 1 can also be selected to include a base and two lamp panels, the base is a polyhedron, and the two lamp panels are respectively installed on two faces of the base, so that the two faces of the base are respectively the first light emitting surface 11 and the second light emitting surface 12.
[0044] The tail lamp 1 can be selected to include a shell and a light source, the light source is in the shell, two faces of the shell are respectively the first light emitting surface 11 and the second light emitting surface 12, the first light emitting surface 11 and the second light emitting surface 12 are transparent structures, so that the light can pass through the first light emitting surface 11 and the second light emitting surface 12. Of course, the tail lamp 1 can also be selected to include a base and two lamp panels, the base is a polyhedron, and the two lamp panels are respectively installed on two faces of the base, so that the two faces of the base are respectively the first light emitting surface 11 and the second light emitting surface 12.
[0045] The tail lamp 1 can be selected to include a shell and a light source, the light source is in the shell, two faces of the shell are respectively the first light emitting surface 11 and the second light emitting surface 12, the first light emitting surface 11 and the second light emitting surface 12 are transparent structures, so that the light can pass through the first light emitting surface 11 and the second light emitting surface 12. Of course, the tail lamp 1 can also be selected to include a base and two lamp panels, the base is a polyhedron, and the two lamp panels are respectively installed on two faces of the base, so that the two faces of the base are respectively the first light emitting surface 11 and the second light emitting surface 12.
[0046] When the back door 3 is closed, the first light emitting surface 11 of the tail lamp 1 emits light outward, and the lamp body on the back door 3 synchronously emits light, so that the lamp body and the first light emitting surface 11 cooperate to have a better visual effect. However, when the trunk of the vehicle is placed with more objects and the back door 3 needs to be opened, the light emitted by the lamp body on the back door 3 will propagate upward and cannot increase the visual effect of the light emitted by the tail lamp 1. At this time, the second light emitting surface 12 is exposed on the tail 2, and the first light emitting surface 11 and the second light emitting surface 12 jointly emit light on the tail 2. The propagation direction of the light passing through the second light emitting surface 12 and the propagation direction of the light passing through the first light emitting surface 11 have an included angle, so that when the second light emitting surface 12 is exposed, the illumination range of the tail lamp 1 can be increased to improve the overall visual effect of the tail lamp 1 when it emits light, so that other drivers or pedestrians can clearly identify that the tail lamp 1 is in the light-emitting state.
[0047] In the requirements of the national standard (GB 4785-2019) for the turn signal lamp, the illumination range of the turn signal lamp on the tail has two parts. The turn signal lamp forms a boundary line in the longitudinal direction of the vehicle at the tail, and the illumination range on the side of the boundary line away from the vehicle in the transverse direction of the vehicle should be greater than 80°, and the illumination range on the side of the boundary line close to the vehicle should be greater than 45°. The illumination range of the existing vehicle tail lamp is concentrated on the side of the boundary line away from the vehicle, and the illumination on the side of the boundary line close to the vehicle relies on the lamp body for auxiliary illumination on the back door. When the back door is opened, the illumination range of the vehicle tail lamp on the side of the boundary line close to the vehicle is very small, which is difficult to meet the requirements of the national standard for the turn signal lamp. The tail lamp provided in the present application has a first light emitting surface 11 and a second light emitting surface 12. When the back door is closed, the first light emitting surface 11 and the lamp body on the back door jointly serve as the turn signal lamp of the tail, so that the tail lamp 1 and the lamp body on the back door cooperate to meet the requirements of the national standard. When the back door is opened, the first light emitting surface 11 and the second light emitting surface 12 are exposed on the tail, and the second light emitting surface 12 illuminates on the side of the boundary line close to the vehicle, so that the illumination range of the tail lamp 1 when the back door is opened meets the requirements of the national standard.
[0048] The vehicle tail structure provided by the application comprises a tail lamp 1, a vehicle tail 2 and a back door 3; the vehicle tail 2 is formed with a trunk 21, the back door 3 is rotatably arranged on the vehicle tail 2, the back door 3 can shield the trunk 21 when being closed and can expose the trunk 21 when being opened, and the tail lamp 1 is arranged on the vehicle tail 2 and at the side of the trunk 21; the tail lamp 1 comprises a first light exit surface 11 and a second light exit surface 12, light can be transmitted through the first light exit surface 11 and the second light exit surface 12, the first light exit surface 11 is exposed to the side of the vehicle tail 2 along the longitudinal direction of the vehicle, and the second light exit surface 12 is arranged towards the trunk 21 along the transverse direction of the vehicle; the second light exit surface 12 is covered when the back door 3 is closed and is exposed when the back door 3 is opened. When the back door 3 is opened, the light transmitted through the first light exit surface 11 and the second light exit surface 12 can all be transmitted outwards on the vehicle tail 2, the propagation direction of the light transmitted through the second light exit surface 12 and the propagation direction of the light transmitted through the first light exit surface 11 have an included angle, so that the exposed second light exit surface 12 can increase the illumination range of the tail lamp 1, the overall visual effect when the tail lamp 1 emits light is improved, and other drivers or pedestrians can clearly observe that the tail lamp 1 is in the light-emitting state.
[0049] Referring to Figures 4 to 10 In some embodiments, the tail lamp 1 comprises a shell 13 and a light-emitting part 14, the first light exit surface 11 and the second light exit surface 12 are formed on the shell 13, and the light-emitting part 14 is arranged in the shell 13, and the light emitted by the light-emitting part 14 can be transmitted through the first light exit surface 11 and the second light exit surface 12.
[0050] In this way, the light emitted by the light-emitting part 14 can illuminate the space outside the shell 13 through the first light exit surface 11 and the second light exit surface 12 on the shell 13, and the shell 13 can protect the light-emitting part 14 from external collision or foreign matter affecting the normal work of the light-emitting part 14.
[0051] Specifically, the shell 13 is a hollow shell structure, the shell structure is a polyhedral structure, two surfaces of the shell structure are transparent, the two transparent surfaces are respectively the first light exit surface 11 and the second light exit surface 12, the light-emitting part 14 is arranged in the shell structure, and the light emitted by the light-emitting part 14 can be transmitted through the first light exit surface 11 and the second light exit surface 12 and emitted out of the shell 13.
[0052] The light-emitting part 14 can be selected as a bulb, the bulb emits light to the periphery to perform the illumination operation through the transparent first light exit surface 11 and the second light exit surface 12 on the shell 13; the light-emitting part 14 can also be selected to comprise a light source and a thick-wall part, the thick-wall part is a transparent part, the light source emits light towards the thick-wall part, the light can propagate in the thick-wall part, the thick-wall part guides the propagation direction of the light, and the light emitted by the light source can improve the uniformity of the light after passing through the thick-wall part.
[0053] Referring to Figures 4 to 10As shown, in some embodiments, the light emitting part 14 comprises a thick-walled piece 141 and a light source 142; the light source 142 is towards the thick-walled piece 141, the surface side of the thick-walled piece 141 is formed with a first light emitting surface 143 and a second light emitting surface 144, the first light emitting surface 143 is arranged opposite to the first light emitting surface 11, and the second light emitting surface 144 is arranged opposite to the second light emitting surface 12.
[0054] The thick-walled piece 141 can guide the light emitted by the light source 142 to be emitted from the first light emitting surface 143 and the second light emitting surface 144 respectively.
[0055] In this way, the light emitted by the light source 142 can be emitted from the first light emitting surface 143 and the second light emitting surface 144 after passing through the thick-walled piece 141, and the uniformity of the light can be improved after passing through the thick-walled piece 141, avoiding the formation of bright spots due to the concentration of light; the light source 142 and the thick-walled piece 141 can have a variety of relative positions, so that the light emitting part 14 can adapt to a variety of shapes of the shell. The first light emitting surface 143 and the second light emitting surface 144 can ensure that the light passing through the thick-walled piece 141 is emitted from the first light emitting surface 11 and the second light emitting surface 12 respectively, improving the guiding effect of the thick-walled piece 141 on the propagation of light, and increasing the amount of light passing through the first light emitting surface 11 and the second light emitting surface 12.
[0056] Specifically, the light source 142 is a bulb or an LED light plate, the thick-walled piece 141 is a block structure, the thick-walled piece 141 can transmit light, and the light enters the thick-walled piece 141 and propagates in the thick-walled piece 141; the thick-walled piece 141 is a polyhedron, two sides of the thick-walled piece 141 serve as the first light emitting surface 143 and the second light emitting surface 144, the light enters the thick-walled piece 141 and propagates inside the thick-walled piece 141 until the light is emitted from the first light emitting surface 143 and the second light emitting surface 144.
[0057] The above-mentioned thick-walled piece 141 can select two sides in the horizontal direction to form the first light emitting surface 143 and the second light emitting surface 144, and the light source 142 can be arranged on one side of the thick-walled piece 141 in the vertical direction, so that the light emitted by the light source 142 can enter the thick-walled piece 141 in the vertical direction, the thick-walled piece 141 is formed with a reflection inclined surface, the reflection inclined surface and the shape of the thick-walled piece 141 cooperate with each other to change the propagation direction of the light entering the thick-walled piece 141, so that the light emitted by the light source 142 can be emitted from the first light emitting surface 143 and the second light emitting surface 144 of the thick-walled piece 141.
[0058] Of course, the light source 142 can also be arranged on one side of the thick-walled piece 141 in the horizontal direction, and the light source 142 is on the side of the thick-walled piece 141 away from the first light emitting surface 143 and the second light emitting surface 144, and the thick-walled piece 141 is formed with a light guide pattern and a light guide surface, so that the light emitted by the light source 142 can enter the thick-walled piece 141 in the horizontal direction and be emitted from the first light emitting surface 143 and the second light emitting surface 144.
[0059] The first light-emitting surface 143 can be a planar structure, just like the first light-emitting surface 11. The first light-emitting surface 143 and the first light-emitting surface 11 are arranged opposite each other and parallel to each other. The second light-emitting surface 144 can be a planar structure, just like the second light-emitting surface 12. The second light-emitting surface 144 can be arranged opposite each other and parallel to each other, ensuring that light emitted from the first light-emitting surface 143 can pass through the first light-emitting surface 11, and light emitted from the second light-emitting surface 144 can pass through the second light-emitting surface 12. Alternatively, the first light-emitting surface 143 can be an arc-shaped surface, facing the first light-emitting surface 11, or the second light-emitting surface 144 can be an arc-shaped surface, facing the second light-emitting surface 12, so that light emitted from the first light-emitting surface 143 can pass through the first light-emitting surface 11, and light emitted from the second light-emitting surface 144 can pass through the second light-emitting surface 12.
[0060] Reference Figure 3 , Figure 4 and Figures 6 to 10 As shown, in some embodiments, the first light-emitting surface 11 is an arc-shaped surface, and the second light-emitting surface 12 is a plane; the first light-emitting surface 143 is parallel to the first light-emitting surface 11, and the second light-emitting surface 144 is parallel to the second light-emitting surface 12.
[0061] With this configuration, the light emitted from the first light-emitting surface 143 can be evenly propagated to the first light-emitting surface 11. The light passing through the curved first light-emitting surface 11 has a wider propagation range, enhancing the visual effect of the taillight 1. The second light-emitting surface 12 makes good use of the shape of the tailgate 3 and the space around the opening of the trunk 21.
[0062] Specifically, the first light-emitting surface 11 is exposed on the rear of the vehicle 2. After passing through the first light-emitting surface 11, most of the light propagates in a direction perpendicular to the first light-emitting surface 11. The first light-emitting surface 11 is an arc-shaped surface, and the light rays passing through each position of the first light-emitting surface 11 are inclined to each other, which can expand the illumination range of the light rays passing through the first light-emitting surface 11 and improve the visual effect of the light rays passing through the first light-emitting surface 11, making it easier for other drivers or pedestrians to observe the light rays passing through the first light-emitting surface 11. The longer the light propagates, the greater the loss of brightness. The first light-emitting surface 143 has the same curvature as the first light-emitting surface 11 and is parallel to each other, that is, the distance from each position of the first light-emitting surface 143 to the first light-emitting surface 11 is equal, which can avoid the loss of brightness due to different light propagation distances and thus avoid affecting the visual effect of the taillight 1.
[0063] The second light exit surface 12 can be arranged on the side wall of the fitting groove of the tail frame of the opening periphery of the trunk 21. The second light exit surface 12 is a plane to facilitate cooperation with the edge of the back door 3, so that the first light exit surface 11 does not occupy the space required by the back door 3. The second light exit surface 144 is parallel to the second light exit surface 12, so that the light rays emitted by the second light exit surface 144 at different positions propagate to the second light exit surface 12 at equal distances.
[0064] Referring to Figure 3 and Figure 4 In some embodiments, the first light exit surface 143 and the second light exit surface 144 are formed on the side of the thick-walled member 141, and the light source 142 is arranged on the top side or the bottom side of the thick-walled member 141.
[0065] In this way, the light source 142 utilizes the space of the housing 13 on the top side or the bottom side of the thick-walled member 141, avoids increasing the size of the housing 13 in the horizontal direction due to the arrangement of the light source 142, and realizes the installation of the light source 142 in the housing 13 while the housing 13 has a small size in the longitudinal direction of the vehicle.
[0066] Specifically, after the tail lamp 1 is installed on the tail 2, the first light exit surface 143 and the second light exit surface 144 are formed on the side of the thick-walled member 141 in the horizontal direction, and the light source 142 is arranged on the top side or the bottom side of the thick-walled member 141 in the vertical direction. The side of the thick-walled member 141 away from the ground in the vertical direction is the top side of the thick-walled member 141. The light source 142 emits light in the vertical direction towards the thick-walled member 141. The light propagates in the thick-walled member 141 in the vertical direction. The thick-walled member 141 can be arranged with a reflection inclined surface. The reflection inclined surface is arranged inclinedly relative to the top side or the bottom side of the thick-walled member 141. After the light passes through the reflection inclined surface, the propagation direction of the light changes. The number of reflection inclined surfaces can be selected to be multiple. Finally, the light propagating in the vertical direction can be emitted from the first light exit surface 143 and the second light exit surface 144 in the horizontal direction after passing through the thick-walled member 141.
[0067] When the tail lamp 1 is arranged on the tail 2, in order to adapt to the vehicle model and avoid the tail lamp 1 protruding from the tail 2 with an excessively large size, the size of the housing 13 in the longitudinal direction of the vehicle is limited. In order to make the light propagate uniformly, the thick-walled member 141 needs to have a large volume, which occupies a large space in the housing 13 in the longitudinal direction of the vehicle, making it difficult to arrange the light source 142 on the side of the thick-walled member 141. Arranging the light source 142 on the top side of the thick-walled member 141 can reasonably utilize the space in the housing 13, and realize the installation of the light source 142 in the housing 13 while the housing 13 has a small size in the longitudinal direction of the vehicle.
[0068] Referring to Figure 5 , Figure 7 and Figure 8As shown, in some embodiments, one side of the thick-walled piece 141 is provided with a light collecting structure 15, and the other side is provided with a light guiding structure 16. The light collecting structure 15 is configured to collect light emitted by the light source 142. The light guiding structure 16 includes a plurality of inclined surfaces 161 arranged at intervals. The inclined surfaces 161 are configured to guide the light collected by the light collecting structure 15 to propagate in the direction of the first light emitting surface 143 and the second light emitting surface 144.
[0069] In this way, the light collecting structure 15 can collect light emitted by the light source 142. The collected light can be emitted from each position of the first light emitting surface 143 and the second light emitting surface 144 through the plurality of inclined surfaces 161, thereby improving the uniformity of light emitted from the first light emitting surface 143 and the second light emitting surface 144, and improving the visual effect when the tail lamp 1 emits light.
[0070] Specifically, the light source 142 can be arranged on the top side of the thick-walled piece 141. The top side of the thick-walled piece 141 is provided with the light collecting structure 15, and the bottom side of the thick-walled piece 141 is provided with the light guiding structure 16. Of course, the light source 142 can also be arranged on the bottom side of the thick-walled piece 141. The bottom side of the thick-walled piece 141 is provided with the light collecting structure 15, and the top side is provided with the light guiding structure 16.
[0071] The light collecting structure 15 described above can be a convex structure, so that light irradiating the convex surface can converge. Of course, the light collecting structure 15 can also be a circular truncated cone structure. The side of the circular truncated cone structure away from the thick-walled piece 141 is a top surface. The diameter of the top surface of the circular truncated cone structure is smaller than that of the bottom surface. The top surface of the circular truncated cone structure can be a convex surface protruding towards the light source 142. Of course, the top surface of the circular truncated cone structure can also be concave to form a light guiding channel. The light guiding channel has a convex surface at one end close to the thick-walled piece 141, which protrudes towards the light source 142. Light emitted by the light source 142 passes through the light guiding channel of the circular truncated cone structure and then enters the thick-walled piece 141 through the convex surface. When the light is in the light guiding channel, the light irradiating the side wall of the light guiding channel can be reflected, so that the light guiding channel guides the light to irradiate the convex surface.
[0072] The plurality of inclined surfaces 161 of the light guide structure 16 described above are formed on the side of the thick-walled member 141 opposite the light collecting structure 15, and the inclined surfaces 161 can be inclined gradually toward the first light emitting surface 143 in the direction in which the light collecting structure 15 faces the light guide structure 16, so that when light strikes the inclined surfaces 161, the light is reflected and deflected toward the first light emitting surface 143, and in the process of propagating, the light passes through the second light emitting surface 144, so that part of the light can be emitted from the second light emitting surface 144. For example, the thick-walled member 141 can have four sides, and the first light emitting surface 143 and the second light emitting surface 144 are formed on two adjacent sides, and the inclined surfaces 161 are formed on the side opposite the first light emitting surface 143, and the inclined surfaces 161 extend to the side on which the second light emitting surface 144 is located, and the inclined surfaces 161 are inclined toward the first light emitting surface 143, and the light propagates toward the first light emitting surface 143 through the inclined surfaces 161, and in the process of propagating, the light on the side on which the second light emitting surface 144 is located can increase the brightness of the second light emitting surface 144, so that the second light emitting surface 144 can also emit light.
[0073] Of course, the thick-walled member 141 can also have more than five sides, and two spaced apart sides are the first light emitting surface 143 and the second light emitting surface 144, and the inclined surfaces 161 are on the sides away from the first light emitting surface 143 and the second light emitting surface 144, and the inclined surfaces 161 extend in the horizontal direction of the thick-walled member 141, so that the area of the inclined surfaces 161 can correspondingly cover the first light emitting surface 143 and the second light emitting surface 144, so that after the light is reflected by the inclined surfaces 161, it can strike the first light emitting surface 143 and the second light emitting surface 144, so that the first light emitting surface 143 and the second light emitting surface 144 can emit light outwardly.
[0074] The first light emitting surface 143 corresponds to the first light emitting surface 11, which needs to emit light and illuminate or transmit signals at the tail 2 under various working conditions, and the first light emitting surface 11 undertakes the main illumination and signal transmission operation of the tail lamp 1; the second light emitting surface 12 is on the side wall of the fitting groove of the tail frame around the opening of the trunk 21, and is only exposed when the back door 3 is opened, and the light at the edge of the first light emitting surface 143 can also propagate to the second light emitting surface 144 and be emitted from the second light emitting surface 144, so the light guide structure 16 can be selected to mainly guide light to the first light emitting surface 143, so that the light emitted by the first light emitting surface 143 is emitted from the first light emitting surface 11 to the outside of the shell 13, so that the first light emitting surface 11 can meet the illumination and signal transmission requirements, and when the second light emitting surface 12 is exposed, light can also be transmitted from the second light emitting surface 12 to improve the visual effect of the tail lamp 1.
[0075] The first light emitting surface 143 and the second light emitting surface 144 can be adjacent to each other on the thick wall member 141, or the first light emitting surface 143 and the second light emitting surface 144 are spaced apart, the inclined surface 161 is spaced apart from the first light emitting surface 143 and the second light emitting surface 144, and the area of the inclined surface 161 covers the first light emitting surface 143 and the second light emitting surface 144, so that the part of the inclined surface 161 corresponding to the first light emitting surface 143 can be inclined towards the first light emitting surface 143, and the part of the inclined surface 161 corresponding to the second light emitting surface 144 can be inclined towards the second light emitting surface 144, so that the light can be guided by the inclined surface 161 and propagated to the first light emitting surface 143 and the second light emitting surface 144 respectively. Of course, the inclined surface 161 can also be a plane, and the area of the inclined surface 161 covers the first light emitting surface 143 and the second light emitting surface 144, and the inclined surface 161 is inclined towards the plane where the two side edges of the first light emitting surface 143 and the second light emitting surface 144 are close to each other, so that the light can be propagated to the first light emitting surface 143 and the second light emitting surface 144 after passing through the inclined surface 161. As long as the light can be propagated towards the first light emitting surface 143 and the second light emitting surface 144 after being reflected by the inclined surface 161, and finally the light can be emitted through the first light emitting surface 143 and the second light emitting surface 144.
[0076] The thick wall member 141 can form a stepped structure on the side away from the light collecting structure 15, and the stepped structure gradually approaches the first light emitting surface 143 in the direction of the light collecting structure 15 towards the light guiding structure 16. The end surface of each step of the stepped structure away from the first light emitting surface 143 can form a plurality of inclined surfaces 161 on the thick wall member 141. The plurality of inclined surfaces 161 are spaced apart in the direction of the light collecting structure 15 towards the light guiding structure 16 and in the direction close to the first light emitting surface 143 on the stepped structure. The light entering the thick wall member 141 through the light collecting structure 15 can be reflected on the plurality of inclined surfaces 161 formed by the stepped structure, so that the light can be propagated towards the first light emitting surface 143.
[0077] The light reflected by different inclined surfaces 161 can be distributed in the direction of the light collecting structure 15 towards the light guiding structure 16, so that the light can be propagated to each position of the first light emitting surface 143, and the light can also be propagated to each position of the second light emitting surface 144, or the light can also pass through each position of the second light emitting surface 144 during propagation, so that the light entering the light guiding structure 16 through the light collecting structure 15 can be emitted from each position of the first light emitting surface 143 and the second light emitting surface 144, improving the uniformity of the light emitted by the tail lamp 1 and improving the visual effect of the tail lamp 1.
[0078] A light distribution pattern can also be formed on the light guiding structure 16, and the light distribution pattern includes a plurality of grooves extending in the direction of the light collecting structure 15 towards the light guiding structure 16 and inclined towards the first light emitting surface 143, so that the light distribution pattern of the light guiding structure 16 can assist in changing the direction of light propagation.
[0079] Referring to Figures 7 to 10 As shown in some embodiments, the thick-walled member 141 is provided with an auxiliary thick wall 17, which is arranged between the light source 142 and the second light emitting surface 144. The auxiliary thick wall 17 is formed with an auxiliary light emitting surface 171 at one end close to the second light emitting surface 144, and the light emitted by the light source 142 can be emitted from the auxiliary light emitting surface 171 to the second light emitting surface 12.
[0080] In this way, the auxiliary thick wall 17 can utilize the space on the top side or the bottom side of the thick-walled member 141, and the auxiliary thick wall 17 can guide the light emitted by the light source 142 to be emitted from the auxiliary light emitting surface 171, so that the light emitted from the auxiliary light emitting surface 171 can complement the light emitted from the second light emitting surface 144, thereby improving the brightness of the light emitted through the second light emitting surface 12, and improving the visual effect of the light emitted through the second light emitting surface 12.
[0081] Specifically, the thick-walled member 141 can be provided with a cuboid structure as the auxiliary thick wall 17, or the thick-walled member 141 can be provided with a protrusion as the auxiliary thick wall 17, and the light can propagate in the auxiliary thick wall 17, which is arranged between the light source 142 and the second light emitting surface 144. The thick-walled member 141 can be provided with an inclined surface or an inclined structure, which is inclined toward the first light emitting surface 143, so that the light propagates through the inclined surface or the inclined structure toward the first light emitting surface 143, and the auxiliary thick wall 17 is in the propagation path of the light, so that the light can propagate through the auxiliary thick wall 17 to the auxiliary light emitting surface 171 and be emitted from the auxiliary light emitting surface 171. Alternatively, the inclined surface or the inclined structure can be inclined toward both the first light emitting surface 143 and the second light emitting surface 144, and the auxiliary thick wall 17 is in the propagation path of the light, so that the light can propagate through the auxiliary thick wall 17 to the auxiliary light emitting surface 171 and be emitted from the auxiliary light emitting surface 171.
[0082] Of course, the thick-walled member 141 can be provided with an inclined surface or an inclined structure toward the auxiliary thick wall 17, so that the light propagates through the inclined surface or the inclined structure toward the auxiliary thick wall 17, and the light propagates through the auxiliary thick wall 17 to be emitted from the auxiliary light emitting surface 171.
[0083] Referring to Figures 7 to 10 As shown in some embodiments, the first light emitting surface 143 and the second light emitting surface 144 are both provided with a light distribution pattern. In this way, the light distribution pattern improves the uniformity of the light emitted from the first light emitting surface 143 and the second light emitting surface 144, thereby improving the visual effect of the tail lamp 1 when the back door 3 is opened and closed.
[0084] Specifically, the first light emitting surface 143 and the second light emitting surface 144 can be provided with a plurality of convex structures as the light distribution patterns, and the plurality of convex structures are uniformly distributed on the first light emitting surface 143 and the second light emitting surface 144. The light emitted from the first light emitting surface 143 needs to pass through the plurality of convex structures, and the light emitted from the second light emitting surface 144 needs to pass through the plurality of convex structures. When the light passes through the plurality of convex structures, refraction and scattering occur, which can make the distribution of the light uniform and avoid the light from being concentrated in a small area to form a bright spot. Of course, the light distribution patterns can also be a plurality of grooves formed by recessing the first light emitting surface 143 and the second light emitting surface 144. The plurality of grooves on the first light emitting surface 143 are uniformly arranged in parallel with each other, and the plurality of grooves on the second light emitting surface 144 are uniformly arranged in parallel with each other. When the light passes through the plurality of parallel grooves, the light is reflected and refracted on the side walls of the grooves, which can improve the uniformity of the light emitted from the first light emitting surface 143 and the second light emitting surface 144.
[0085] Referring to Figure 3 , Figure 5 and Figures 7 to 10 , in some embodiments, the first light emitting surface 143 and the second light emitting surface 144 are adjacent to each other and inclined to each other on the thick-walled member 141. In this way, the distance between the first light emitting surface 143 and the second light emitting surface 144 is short, and the overall structure of the thick-walled member 141 is compact, so that the tail lamp 1 can maintain a small size.
[0086] Specifically, the housing 13 is a polyhedron, and two adjacent side surfaces of the housing 13 are inclined to each other to serve as the first light emitting surface 11 and the second light emitting surface 12, respectively. The thick-walled member 141 is a polyhedron, and two adjacent side surfaces of the thick-walled member 141 serve as the first light emitting surface 143 and the second light emitting surface 144, respectively. The first light emitting surface 11 and the second light emitting surface 12 are inclined to each other, so that when the first light emitting surface 11 is exposed on the vehicle tail 2, the second light emitting surface 12 can be arranged in the lateral direction of the vehicle towards the trunk 21.
[0087] Referring to Figure 3 , Figure 4 and Figure 5 , in some embodiments, the housing 13 includes a rear shell 132 and a face cover 131, the face cover 131 is connected to one side of the rear shell 132, and the light emitting part 14 is installed in the space surrounded by the rear shell 132 and the face cover 131. The first light emitting surface 11 and the second light emitting surface 12 are formed on the face cover 131.
[0088] In this way, when the rear shell 132 and the face cover 131 are separated, the light emitting part 14 can be placed in the rear shell 132, and then the face cover can be installed to complete the assembly operation of the tail lamp 1, thereby improving the operation convenience of installing the light emitting part 14 in the housing 13.
[0089] Specifically, the rear shell 132 is a box structure with a bottom surface and multiple side surfaces, and the box structure has an opening. The mask 131 is a panel structure, and the mask 131 is transparent and has two adjacent surfaces as the first light exit surface 11 and the second light exit surface 12. The mask 131 is mounted on the opening of the rear shell 132, so that the mask 131 can cover the rear shell 132, and the mask 131 and the rear shell 132 together form a closed space. When the mask 131 is separated from the rear shell 132, the light emitting part 14 can be mounted inside the rear shell 132 through the opening, and then the mask 131 is connected with the rear shell 132, so that the operation of mounting the light emitting part 14 in the rear shell 132 is completed.
[0090] The mask 131 and the rear shell 132 can be connected by clamping or by bolts, as long as the mask 131 can be connected with the rear shell 132 to form a space for accommodating the light emitting part 14.

[0093] By using the vehicle tail structure as described above in the vehicle, when the back door 3 is closed, light passes through the first light exit surface 11 to illuminate or transmit signals, and when the back door 3 is opened, light passes through the first light exit surface 11 and the second light exit surface 12 to illuminate or transmit signals, which improves the illumination range of the tail lamp 1 when the back door 3 is opened, and improves the visual effect of the tail lamp 1, so that other drivers or pedestrians can easily observe the tail lamp 1.
[0094] The vehicle tail structure and the vehicle provided by the application are used as follows: the light emitting part 14 is installed in the rear shell 132, the mask 131 is installed on the rear shell 132, the outer shell 13 is connected with the vehicle tail 2, the first light emitting surface 11 is exposed on the vehicle tail 2, and the second light emitting surface 12 is on the side wall of the adaptive slot of the vehicle tail frame at the opening periphery of the trunk 21. When the back door 3 is closed, the second light emitting surface 12 is covered, the light emitted by the light source 142 is emitted into the thick wall part 141 through the light collecting structure 15, and is emitted from the first light emitting surface 143 and the second light emitting surface 144 through the plurality of inclined surfaces 161 of the light guide structure 16, the light emitted from the first light emitting surface 143 is emitted out of the outer shell 13 through the first light emitting surface 11, the light emitted through the first light emitting surface 11 is propagated outward on the vehicle tail 2, and the light emitted from the second light emitting surface 144 is emitted out of the outer shell 13 through the second light emitting surface 12 and is blocked by the back door 3.

[0095] When the back door 3 is opened, the second light emitting surface 12 is exposed, the light source 142 emits light from the first light emitting surface 143 and the second light emitting surface 144 through the thick wall part 141, the light emitted from the first light emitting surface 143 is emitted out of the outer shell 13 through the first light emitting surface 11, the light emitted from the second light emitting surface 144 is emitted out of the outer shell 13 through the second light emitting surface 12, the light emitted through the first light emitting surface 11 and the second light emitting surface 12 is propagated outward on the vehicle tail 2, the light emitted by the lamp body on the back door 3 is propagated upward, other drivers and pedestrians cannot see the light emitted by the lamp body on the back door 3, the light emitted through the second light emitting surface 12 is propagated on the side of the first light emitting surface 11, the propagation range of the light emitted by the tail lamp 1 is increased, the visual effect when the tail lamp 1 emits light is improved, and other drivers and pedestrians can accurately observe that the tail lamp 1 is on and receive the signal transmitted by the driver of the vehicle.
