[0037] The vehicle rear combination lamp 1 comprises a mask 10, a shell 20, a light-emitting assembly 30 and a breathable membrane 22. The mask 10 and the shell 20 cooperate with each other to form a receiving space 70, the shell 20 is used to be connected to the body of the vehicle, the mask 10 is located on the side of the shell 20 away from the body of the vehicle, the light-emitting assembly 30 is located in the receiving space 70, and the light-emitting assembly 30 is used to emit light to the mask 10, and transmit light to the outside of the receiving space 70 through the mask 10. Among them, the shell 20 is provided with a first vent 21 connecting the inside and outside of the receiving space 70, and the breathable membrane 22 covers the first vent 21, and the breathable membrane 22 allows airflow to enter and exit the receiving space 70 through the first vent 21.

[0038] The mask 10 is a plastic plate with a part or all of the area being transparent. The mask 10 is connected to the side of the shell 20 facing away from the vehicle body. The mask 10 is used to transmit the light beam to reflect the driving status of the vehicle and send a signal to the rear vehicle. The surrounding side where the mask 10 is connected to the shell 20 may be provided with a protrusion, and the shell 20 may be provided with a groove at a position corresponding to the protrusion. The mask 10 and the shell 20 may be connected together by hot plate welding to connect the protrusion and the groove. The mask 10 and the shell 20 cooperate with each other to form a receiving space 70, so that there is no gap at the connection part between the mask 10 and the shell 20, so as to prevent foreign matter and water outside the receiving space 70 from entering the interior of the vehicle combination lamp, thereby preventing the safety hazard caused by it. The material of the mask 10 may be any one or more of polycarbonate (PC), polypropylene (PP), polyamide (PA), polyphenylene sulfide (PBT) and acrylic (PMMA).

[0039] The light-emitting component 30 is arranged inside the accommodation space 70. The light-emitting component 30 can be fixed on the housing 20 by a plurality of screws. The housing 20 is connected to the body of the vehicle, and finally the rear combination lamp 1 of the vehicle is connected to the rear of the vehicle. The light-emitting component 30 emits light to the mask 10 to display the driving status of the vehicle. The housing 20 is also provided with a plurality of first vents 21 on the side close to the vehicle body. The first vents 21 are used to achieve heat exchange inside and outside the accommodation space 70, so that when the heat emitted by the light-emitting component 30 during operation can be dissipated through the first vents 21, the air outside the accommodation space 70 can also enter the accommodation space 70. In addition, a breathable membrane 22 is provided on the housing 20. The breathable membrane 22 is used to cover the first vents 21. The breathable membrane 22 can be arranged on the side of the housing 20 close to the vehicle body. The breathable membrane 22 allows air flow to pass through and prevents foreign matter such as water and dust from passing through. The material of the breathable membrane 22 can be one material or a composite material formed by multiple polymer materials such as high-density polyethylene (HDPE), polyurethane (PU), polylactic acid (PLA) and wood cellulose, and the present application does not limit this.

[0040] Through the above embodiment, the mask 10 and the shell 20 form a receiving space 70, the light emitting component 30 is located in the receiving space 70, and the decorative ring 40 is installed between the mask 10 and the light emitting component 30. The light emitting component 30 will generate a lot of heat when working for a long time, and the shell 20 is provided with a first vent hole 21 connecting the inside and outside of the receiving space 70. The first vent hole 21 is covered by a breathable membrane 22, thereby preventing foreign matter from entering the receiving space 70, and also enabling heat exchange between the inside and outside of the receiving space 70 through the first vent hole 21, so as to dissipate heat for the rear combination lamp 1 of the vehicle.

[0041] In some embodiments, the vehicle rear combination lamp 1 further includes a decorative ring 40, which is located in the accommodating space 70 and fixedly connected to the housing 20. The decorative ring 40 is disposed between the light emitting assembly 30 and the mask 10, and the decorative ring 40 and the mask 10 are spaced apart in the direction of the light emitted by the light emitting assembly 30. The decorative ring 40 can pass the light beam emitted by the light emitting assembly 30, and then the light beam is emitted to the mask 10. There is a gap between the lower side of the decorative ring 40 in the vertical direction perpendicular to the direction of the light emitting assembly 30 and the housing 20, so that the heat emitted by the light emitting assembly 30 can be transferred to between the decorative ring 40 and the mask 10 through the gap, so that the heat emitted by the light emitting assembly 30 is transferred to the outside through the mask 10, so that the vehicle rear combination lamp 1 dissipates heat. When the temperature difference between the inner side of the mask 10 and the outer side of the mask 10 is large, condensation may accumulate on the mask 10, and the heat emitted by the light emitting assembly 30 can also evaporate the condensation on the mask 10, and the steam can be discharged through the first vent 21.

[0042] See also Figures 4 to 6 , Figure 4 yes Figure 1 A cross-sectional view of the rear combination lamp of the vehicle shown along the BB direction; Figure 5 yes Figure 1 The disassembled schematic diagram of the vehicle rear combination lamp is shown; Figure 6 yes Figure 1 A structural schematic diagram of an embodiment of a decorative ring is shown.

[0043] In some embodiments, the bezel 40 is provided with a plurality of second vents 41, which penetrate the opposite surfaces of the bezel 40 along the direction of light emitted by the light emitting component 30, so that the heat emitted by the light emitting component 30 can also flow between the bezel 40 and the mask 10 through the second vents 41. The second vents 41 can be arranged below the corresponding positions of the light emitting component 30 and the bezel 40 to increase the channel for heat to be transferred from the light emitting component 30 to the gap between the mask 10 and the bezel 40, so that the heat transfer speed is faster. The bezel 40 can also be provided with a decorative pattern structure, and the second vents 41 can be arranged in the texture of the pattern structure, so as to improve the heat dissipation capacity of the lamp while ensuring the beautiful shape of the lamp.

[0044] In some embodiments, in addition to the gap between the lower side of the decorative ring 40 and the housing 20 in the vertical direction, there is also a gap between the upper side of the decorative ring 40 and the housing 20 in the vertical direction. So that the heat between the decorative ring 40 and the mask 10 can be transferred to the first vent 21 through the gap. The outside air also enters the accommodation space 70 through the first vent 21, thereby reducing the temperature inside the accommodation space 70. Since the outside temperature is lower than the temperature inside the accommodation space 70, after the outside air enters the accommodation space 70, it drives the heat emitted by the light-emitting component 30 to be transferred to the gap on the lower side of the decorative ring 40 and the second vent 41 along the vertical direction. Therefore, the outside air can drive the heat emitted by the light-emitting component 30 in the accommodation space 70 along the route of the first vent 21-light-emitting component 30-second vent 41 and the gap on the lower side of the decorative ring 40-between the decorative ring 40 and the mask 10-the gap on the upper side of the decorative ring 40-the first vent 21 to achieve cyclic heat dissipation.

[0045] In some embodiments, the light emitting assembly 30 may include a position light 31 and two brake lights 32. The position light 31 is arranged along the direction in which the housing 20 extends. The two brake lights 32 are arranged at intervals in the direction in which the housing 20 extends. The position light 31 may be located above the brake lights 32 in the vertical direction. The positions of the two brake lights 32 may correspond to the positions of the first vent holes 21 on the housing 20, so that the heat dissipation distance from the brake lights 32 to the first vent holes 21 is relatively short. The position light 31 may include a plurality of position light PCB boards, a position light harness, and a main harness interface. The plurality of position light PCB boards are arranged at intervals along the direction in which the housing 20 extends. The plurality of position light PCB boards are connected by the position light harness. The two position light PCB boards near the two brake lights 32 are provided with a main harness interface, the main harness interface is connected to the main harness, the main harness is connected to the power supply, and the main harness is located on the housing 20 corresponding to the two brake lights 32. The position light PCB board may be fixed to the housing 20 by screws. The two brake lights 32 include a brake light PCB board and a main harness interface, and the brake lights 32 are connected to the main harness. The position light PCB and the brake light PCB may be provided with a plurality of LED lamp beads, and the heat emitted by the LED lamp beads is lower than that of other light sources, so that the heat dissipation requirement of the vehicle rear combination lamp 1 is small, and the heat dissipation is sufficient without a heat dissipation device without affecting the life of the lamp. The position light PCB is arranged at intervals along the direction in which the housing 20 extends, and the plurality of LED lamp beads are evenly arranged at intervals on the position light PCB and the brake light PCB. Specifically, the number of the position light PCB and the brake light PCB may be 5 and 2, respectively.

[0046] In some embodiments, a plurality of forced release structures may be provided on the housing 20, and the forced release structures are used to fix the position light harness connected to the adjacent position light PCB board, and also to fix the main harness connected to the brake light 32. The forced release structure is integrally formed with the housing 20, and has a certain plastic deformation ability, which can prevent the installation of the position light 31 and the brake light 32 from being affected by the harness being too long or too hard, and can also prevent abnormal noise from being generated by the harness due to vibration during driving of the vehicle.

[0047] In some embodiments, the vehicle rear combination lamp 1 is provided with a light diffuser 50, which is arranged inside the accommodation space 70, and is extended along the direction in which the housing 20 extends. The light diffuser 50 is arranged between the decorative ring 40 and the position lamp 31, and is located above the brake lamp 32 and corresponds to the position lamp 31 in the direction in which the light emitting assembly 30 emits light, so that the light beam emitted by the position lamp 31 can be transmitted to the mask 10 through the light diffuser 50. The light diffuser 50 can make the light beam emitted by the position lamp 31 uniform through a series of reflections and scatterings, thereby achieving the purpose of optimizing the brightness uniformity of the entire light board, which can not only make the light beam emitted by the lamp have a certain clarity and brightness, but also not irritate the human eye.

[0048] In some embodiments, the accommodation space 70 is further provided with a reflector 33, and the brake light 32 is connected with the reflector 33 in cooperation. The reflector 33 may include a reflector surface and a beam channel. The reflector 33 is located below the brake light 32. The optical axis of the light beam emitted by the brake light 32 is vertically downward. The light beam emitted by the brake light 32 is reflected by the reflector surface to transmit the light beam to the mask 10 through the beam channel. The brake light 32 can be inserted into the reflector 33 holder, and the reflector 33 and the brake light 32 can be further fixed by two clips. The reflector 33 may be provided with a screw hole, and the two reflectors 33 connected with the two brake lights 32 can be fixed to the housing 20 together with the light diffuser 50 by multiple screws. The reflector 33 may be provided with a notch on the lower side in the vertical direction, so that the heat emitted by the brake light 32 can be transferred to the gap between the lower side of the decorative ring 40 and the housing 20 and the second vent 41 through the notch, and then the heat is transferred to between the decorative ring 40 and the mask 10.

[0049] In some embodiments, a shading pad can be provided between the reflector 33 and the decorative ring 40. The shading pad can be attached to the peripheral side of the light beam channel of the reflector 33 to fill the gap between the decorative ring 40 and the reflector 33. Under the condition of ensuring the safe assembly gap of each part, the brake light 32 is ensured not to leak light, not to cause cross-light with the position light 31, and the vehicle driving signal is ensured to be accurate, thereby improving safety. The shading pad can be made of soft, opaque foam, which has a large compression capacity and can effectively shield the brake light 32.

[0050] In some embodiments, the bezel 40 is further provided with a first light emitting area 42 at a position corresponding to the position light 31, so that the light beam emitted by the position light 31 passes through the light homogenizing plate 50, then passes through the first light emitting area 42, and finally emits to the mask 10. A second light emitting area 43 is further provided at each position corresponding to the two brake lights 32, so that the light beam emitted by the brake lights 32 first passes through the reflector 33, then passes through the second light emitting area 43, and finally emits to the mask 10. The first light emitting area 42 is extended along the direction in which the housing 20 extends, like the position light 31, and the two second light emitting areas 43 are located on the same side of the first light emitting area 42 and are spaced apart along the direction in which the first light emitting area 42 extends. The second light emitting area 43 is spaced apart below the first light emitting area 42 in the vertical direction. The first light emitting area 42 can be divided into a plurality of parts, and the plurality of parts can be spaced apart along the direction in which the housing 20 extends. The first light exiting area 42 may be provided with a thick-walled member, which is fixedly connected to the first light exiting area 42, so that the light beam emitted by the position lamp 31 passes through the light homogenizing plate 50 and the thick-walled member successively, and the thick-walled member can further make the brightness of the light beam emitted by the position lamp 31 more uniform and more penetrating. The second light exiting area 43 may be provided with a lens, which is fixedly connected to the decorative ring 40, and the lens can gather the light beam emitted by the brake lamp 32, so that the brightness of the brake lamp 32 is higher, thereby improving the safety factor of the vehicle.

[0051] In some embodiments, when fixing the decorative ring 40 to the housing 20, screws can be driven from the side of the housing 20 close to the vehicle body to completely lock the reflector 33, the light diffuser 50 and the decorative ring 40 on the housing 20. In addition, the decorative ring 40 can be pre-fixed on the housing 20 by inserting multiple sheet structures provided on the decorative ring 40 into multiple buckle grooves provided on the housing 20, and one sheet structure corresponds to one buckle groove. The buckle groove guides the sheet structure, facilitates the positioning of the decorative ring 40, and prevents the decorative ring 40 from falling off due to the flipping of the housing 20, thereby reducing the difficulty of assembly, shortening the installation time, and reducing the number of locking screws and the cost of parts.

[0052] In some embodiments, since the accommodation space 70 is connected to the outside world through the first vent 21, and the outside air has a certain humidity, a plurality of desiccants may be provided in the accommodation space 70, and the desiccants are provided between the housing 20 and the light-emitting assembly 30. The desiccant may be fixed to the housing 20 by an adhesive. The desiccant may absorb excess moisture in the accommodation space 70 to ensure that the components inside the accommodation space 70 are in a relatively dry environment, reduce the risk of fogging, prevent the brake light 32 and the position light 31 from short-circuiting, and slow down the aging speed of the plastic products inside the accommodation space 70. The number of desiccants may be designed according to actual conditions, and the present application does not limit the number of desiccants.
