Description
Technical Field
[0001] This application relates to the field of vehicle technology, specifically to light-emitting components, vehicle bodies, and vehicles. Background Technology
[0002] Vehicle bodies typically include light-emitting components that provide functions such as nighttime illumination and warning signals. With the maturity and widespread adoption of LED technology, traditional light-emitting components generally employ a direct-light LED structure.
[0003] In the prior art, an automotive taillight is provided, including a functional module and a mounting module. The mounting module is located below the functional module and is used to install and fix the functional module. The functional module includes a lamp cover, a reflector, a circuit board, and a mounting bracket. The mounting bracket has protruding feet, and the circuit board has corresponding feet holes. The circuit board is mounted on the mounting bracket, with the feet passing through the feet holes, so that the circuit board is in close contact with the mounting bracket. A lamp is mounted on one side of the circuit board, and the reflector has mounting holes corresponding to the lamp position. The reflector is located on the side of the circuit board away from the mounting bracket and overlaps with the circuit board. The lamp passes through the mounting holes and protrudes from one side of the reflector. A protruding post is provided on the side of the reflector that is in contact with the circuit board. The position of the post corresponds to the position of the feet on the mounting bracket. The post is inserted into the interior of the feet, so that the reflector, circuit board, and mounting bracket are tightly fitted.
[0004] In existing vehicle taillights, the direct-light structure makes it difficult to achieve uniform light diffusion, which can easily lead to the formation of bright spots with excessively high local brightness on the surface of the light-emitting components, affecting the overall lighting effect of the light-emitting components. Utility Model Content
[0005] One objective of this application is to provide a light-emitting component to solve the problem of how to improve the uniformity of light diffusion in the light-emitting component. A second objective of this application is to provide a vehicle body. A third objective of this application is to provide a vehicle.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] In a first aspect, embodiments of this application provide a light-emitting component, including: a housing, a light source, a light guide, and a reflector, wherein the light source is connected inside the housing; the light guide is connected inside the housing and disposed on the light-emitting side of the light source; the reflector includes a reflective surface, and the light guide guides the light emitted by the light source to the reflective surface, the reflective surface facing the light-emitting side of the light-emitting component.
[0008] According to the above technical means, the housing serves as the frame of the light-emitting component, with both the light source and the light guide located inside. The housing provides support and protection for the light source and the light guide. The light source emits light, and the light guide is installed inside the housing on one side of the light-emitting direction. It guides the light emitted by the light source to the reflector. The reflector has a reflective surface facing the light-emitting side of the light-emitting component. When the light guide guides the light to the reflective surface, the reflective surface reflects the light back to the light-emitting side of the light-emitting component, thus illuminating it. In this way, the light is guided by the light guide to the reflector and reflected out, preventing the light emitted by the light source from shining directly out. This achieves more uniform light diffusion, avoids localized overbrightness in the light-emitting component, and improves the lighting effect of the light-emitting component.
[0009] In some embodiments, the light guide includes a light guide portion and a reflective portion. The light-incident side of the light guide portion faces the light-outceasing side of the light source, and the light-outceasing side of the light guide portion faces the reflective portion. The reflective portion is located on the side of the light guide portion away from the reflective portion and is used to reflect the light from the light guide portion to the reflective portion.
[0010] According to the above technical means, the light guide part serves as the main channel for light. The light-incident side of the light guide part faces the light-out direction of the light source and can directly receive the light emitted by the light source. The light-out side faces the reflector and can guide most of the light to the reflective surface of the reflector. The reflective part is located on the other side of the light guide part. When the light propagates inside the light guide part, some of the light diffuses away from the reflector. The reflective part can redirect some of the light back to the reflector.
[0011] In some embodiments, the light source is located on one side of the light guide in a first direction, and the reflector is located on one side of the light guide in a second direction. The first direction is perpendicular to the second direction. The reflective part includes a reflective surface facing the reflective surface and is located on the side facing the reflective surface.
[0012] According to the above technical means, the light source and the reflector are located in two vertical directions of the light guide. The reflective surface of the reflector can reflect the diffused light from the light guide to the reflective surface of the reflector, which further improves the light guiding efficiency.
[0013] In some embodiments, both the reflective surface and the reflective surface are inclined relative to the second direction.
[0014] According to the above-mentioned technical means, the reflective surface of the reflective part and the reflective surface of the reflector are both tilted at a certain angle relative to the second direction, which allows the light from the reflective surface to be guided to the reflective surface at the optimal angle, and then the light is scattered through the reflective surface, further optimizing the light propagation efficiency.
[0015] In some embodiments, the reflective surface includes a first end and a second end. Along a second direction, the first end is located on the side of the second end closer to the reflector. Along a direction perpendicular to the reflective surface, the distance between the first end and the reflector is greater than the distance between the second end and the reflector.
[0016] According to the above technical means, by making the distance between the first end and the reflector greater than the distance between the second end and the reflector, the inclined setting of the reflective surface can make the light more accurately reflect to the reflective surface, reduce light loss, and improve the light guiding efficiency.
[0017] In some embodiments, a light-shielding element is also included, which is located on the light-emitting side of the light guide and on the side opposite to the reflective surface.
[0018] According to the above technical means, by setting up a light-shielding component, light leakage from the light guide can be blocked, preventing light from scattering in unwanted directions, ensuring that the light is concentrated and emitted from a preset direction, and improving the efficiency of light emission.
[0019] In some embodiments, the housing includes a lens and a mounting bracket, the lens being mounted on one side of the mounting bracket in a first direction, the lens including a first portion and a second portion, the first portion being connected to one end of the second portion in a second direction and located on the side of the second portion away from the mounting bracket in the first direction, the first portion and the mounting bracket defining a first mounting space, a light source and a light guide being mounted in the first mounting space, and a reflector being connected to the side of the second portion away from the mounting bracket in the first direction.
[0020] According to the above technical means, the first part of the lens and the mounting bracket form a first mounting space, the light source and the light guide are set in the first mounting space, and the reflector is installed on the outside of the second part of the lens, forming an integral light-emitting component structure.
[0021] In some embodiments, a flexible element is further included, disposed between the reflector and the second portion.
[0022] According to the above-mentioned technical means, by setting a flexible component between the reflector and the second part, the impact caused by vibration or collision between the reflector and the second part can be reduced, thus playing a protective role.
[0023] Secondly, embodiments of this application also provide a vehicle body that includes the light-emitting component of the first aspect.
[0024] Since the vehicle body provided in this application includes the light-emitting component in the first aspect, it can solve the same technical problems as the light-emitting component described above and achieve the same technical effects, so it will not be described again here.
[0025] Thirdly, embodiments of this application also provide a vehicle that includes the body described in the second aspect above.
[0026] Since the vehicle provided in this application embodiment includes the body in the second aspect, it can solve the same technical problems as the above-mentioned body and achieve the same technical effects, so it will not be described again here. Attached Figure Description

[0044] Please see Figure 1 This application provides a vehicle. The vehicle can be a pure electric vehicle, a hybrid electric vehicle, a plug-in hybrid electric vehicle, a range-extended electric vehicle, a gasoline vehicle, etc.
[0045] In some embodiments, the vehicle includes a body, which is a frame that supports functional components such as seats, engines, motors, etc. The body includes a body body and light-emitting components 100. The light-emitting components 100 are distributed at multiple locations on the body body. For example, the light-emitting components 100 may be located at the front of the body body, the rear of the body body, rearview mirrors, etc. The light-emitting components 100 can be used for illumination or to transmit information through different light modes to ensure driving safety.
[0046] In some examples, the light-emitting component 100 can be a vehicle headlight, taillight, hazard lights, turn signals, etc., and this application does not specifically limit its use. In other examples, the light-emitting component 100 can also be used in other devices, such as ships, aircraft, machinery, etc., and this application does not specifically limit its use either. This application is illustrated by example using the light-emitting component 100 in a vehicle.
[0047] In some embodiments, the light-emitting component 100 may include a housing 110, a light source 140, a light guide 120, and a reflector 130, with the light source 140 connected inside the housing 110; the light source 140 is the core of the light-emitting component 100 and is used to generate light.
[0048] The light guide 120 is connected inside the housing 110 and is located on the light-emitting side of the light source 140. The light guide 120 is used to guide the light emitted by the light source 140. For example, the light guide 120 is fixed inside the housing 110 and faces the light-emitting side of the light source 140. For instance, the light-emitting center of the light source 140 and the light-incident side of the light guide 120 are precisely aligned to ensure that the light emitted by the light source 140 can enter the light guide 120 to the maximum extent and reduce the loss of initial light.
[0049] The reflector 130 is fixed at a preset position to reflect the light guided by the light guide 120. The reflector 130 may include a reflective surface 131. The light guide 120 guides the light emitted by the light source 140 to the reflective surface 131, which faces the light-emitting side of the light-emitting component 100.
[0050] Specifically, the housing 110 serves as a protective shell and support structure for the light-emitting component 100, and can securely house the light source 140 and the light guide 120 inside the housing 110, preventing external dust, rainwater, and vibrations from vehicle operation from affecting the internal components of the light source 140 and the light guide 120. In some examples, a dedicated planar-mounted light source 140 is provided on the inner side of the housing 110.
[0051] When the light source 140 emits light, the light enters from the light-incident side of the light guide 120 and is conducted inside the light guide 120. The reflector 130 includes a reflective surface 131, which faces the light-emitting side of the light-emitting component 100. When the light guide 120 guides the light to the reflective surface 131, the reflective surface 131 reflects the light back to the light-emitting side of the light-emitting component 100, thus illuminating the light. In this way, the light is guided by the light guide 120 to the reflector 130 and reflected out, preventing the light emitted by the light source 140 from shining directly out. This achieves more uniform light diffusion, avoids localized overbrightness in the light-emitting component 100, and improves the lighting effect of the light-emitting component 100. Furthermore, uniform light illumination also improves visual comfort and reduces safety hazards.
[0052] In some embodiments, the light guide 120 includes a light guide portion 121 and a reflector portion 122. The light-incident side of the light guide portion 121 faces the light-emitting side of the light source 140, and the light-emitting side of the light guide portion 121 faces the reflector 130. The reflector portion 122 is located on the side of the light guide portion 121 away from the reflector 130, and the reflector portion 122 is used to reflect the light from the light guide portion 121 to the reflector 130.
[0053] The light guide section 121 serves as a light channel, with its light-incident side facing the light-emitting side of the light source 140. This allows the light emitted from the light source 140 to directly and efficiently enter the interior of the light guide section 121, minimizing light refraction loss and ensuring that the light guide section 121 receives the light emitted from the light source 140 to the maximum extent. The reflector section 122 is located on the side of the light guide section 121 away from the reflector 130. When light propagates through the light guide section 121, the reflector section 122 can intercept the light diffused by the light guide section 121, thereby guiding the light to the light-emitting side of the light guide section 121 and directing it toward the reflective surface 131 of the reflector 130. Through the cooperation of the light guide section 121 and the reflector section 122, the light emitted from the light source 140 is fully utilized, reducing unnecessary light loss. At the same time, the light reflected by the reflector 130 is more uniform and stable, improving the overall light emission effect of the light-emitting component 100.
[0054] In some examples, the light guide 120 can be a light guide strip, and the length direction of the light guide strip can be perpendicular to the arrangement direction of the light source 140 and the light guide 120. The light guide strip can be provided with a light guiding channel, the light guide channel forms a light guide portion 121, and the portion of the side wall of the light guide strip surrounding the light guide channel on the side of the light guide portion 121 away from the reflector 130 forms a reflective portion 122.
[0055] In some other examples, the light guide 120 can also be a light guide plate, with the light-incident side of the light guide plate corresponding to the light source 140. The interior of the light guide plate is provided with laser dots or etched dots, so that the light is continuously scattered and reflected when it propagates in the light guide plate, and finally emitted uniformly from the preset light-out side to achieve a uniform light emission effect.
[0056] In other examples, the light guide 120 can also be a light guide post or a light guide film, as long as it can achieve a high-efficiency light guiding effect, which will not be described in detail here.
[0057] In some embodiments, the light source 140 is located on one side of the light guide 120 in the first direction X, and the reflector 130 is located on one side of the light guide 120 in the second direction Y. The first direction X is perpendicular to the second direction Y. For example, the first direction X can be the length direction of the vehicle, and the second direction Y can be the height direction of the vehicle. The reflector 122 includes a reflective surface 1221 facing the reflective surface 131, and the reflective surface 1221 is located on the side facing the reflective surface 131. For example, the light guide 120 is a light guide strip, and at least a portion of the inner wall surface of the portion of the sidewall of the light guide strip that forms the conduit channel on the side of the light guide 121 away from the reflector 130 forms the reflective surface 1221.
[0058] Specifically, the light source 140 is located on one side of the light guide 120 in the first direction X, and the reflector 130 is located on one side of the light guide 120 in the second direction Y. The reflector 122 is used to receive the light propagated by the light guide 121. When the light propagates in the light guide 121, it is affected by the reflector 1221. When the light diffuses at different angles and shines on the reflector 1221, the reflector 1221 accurately reflects the light to the reflector 131 of the reflector 130 according to the preset reflection path. The light guided by the reflector 122 and the light guided by the main path of the light guide 121 converge and act together on the reflector 131 of the reflector 130. This not only reduces the light loss, but also increases the total amount of light received by the reflector 130. The combination of the two makes the light emitted by the light source 140 more fully utilized and improves the light emission effect of the light-emitting component 100.
[0059] In some embodiments, both the reflective surface 1221 and the reflective surface 131 are inclined relative to the second direction Y.
[0060] Specifically, the reflective surface 1221 of the reflective part 122 and the reflective surface 131 of the reflector 130 are both tilted at a certain angle relative to the second direction Y, so that the light reflected by the reflective surface 1221 can hit the reflective surface 131 at a better angle, and then the light is scattered through the reflective surface 131, which further optimizes the light propagation efficiency.
[0061] In some other embodiments, at least one of the reflective surface 1221 and the reflective surface 131 may also be parallel to the second direction Y. In this case, since the light emitted by the light source 140 diffuses in multiple directions, the light that shines on the reflective surface 1221 can also be reflected back to the reflective surface 1221, which can also reduce the loss of light.
[0062] This application is illustrated by way of example, with both the reflective surface 1221 and the reflective surface 131 being tilted relative to the second direction Y.
[0063] In some embodiments, the light-emitting surface and the reflective surface 131 are inclined, and the extension surfaces of the light-emitting surface and the reflective surface 131 intersect. The tilt angle of the reflective surface 1221 matches the incident angle of the light in the light guide 120, so that when the light is reflected by the reflective surface 1221, the reflection angle and the incident angle follow optical laws, reducing light scattering caused by angle deviation. After being received by the inclined reflective surface 1221, a relatively concentrated beam of light is formed, which falls on the reflective surface 131 of the reflector 130 and can cover the effective area of the reflective surface 131, avoiding the waste caused by the light only hitting the edge of the reflective surface 131. Subsequently, the reflective surface 131 of the reflector 130 scatters the light out at an appropriate tilt angle, and the angle of the reflective surface 131 matches the light emission requirements of the light-emitting component 100. For example, if the light-emitting component 100 is used for a vehicle's turn signal, the reflective surface 131 will tilt and scatter the light to both sides of the vehicle body, ensuring that surrounding vehicles and pedestrians can clearly see it from different angles. For example, the light-emitting component 100 is used for interior ambient lighting, while the reflective surface 131 diffuses the light gently onto the interior surface at a relatively gentle angle, avoiding the generation of glaring light spots.
[0064] In some embodiments, the reflective surface 1221 includes a first end and a second end. Along the second direction Y, the first end is located on the side of the second end closer to the reflector 130. Along a direction perpendicular to the reflective surface 131, the distance between the first end and the reflective surface 131 is greater than the distance between the second end and the reflective surface 131. That is, the tilt angle of the reflective surface 1221 relative to the second direction Y is greater than the tilt angle of the reflective surface 131 relative to the second direction Y.
[0065] Specifically, when light is transmitted within the light guide 121, the angle at which the light is incident on the reflective surface 1221 is not entirely consistent. Some light rays may not accurately reach the predetermined reflector 130 surface due to the deviation in reflection angle, and instead deviate to the non-target area of the light guide 121, thus causing light loss. By making the distance between the first end of the reflective surface 1221 and the reflective surface 131 greater than the distance between the second end and the reflective surface 131, the tilted reflective surface 1221 can be adapted to the incident characteristics of light. When light is projected onto the surface of the reflective surface 1221, more light rays can be reflected to the reflective surface 1221 under the guidance of the reflective surface 1221. After receiving the reflected light, the reflector 130 can further transmit or emit the light from the reflective surface 131 in a predetermined direction. The ineffective scattering caused by the light deviating from the reflector 130 is greatly reduced, allowing the light rays to concentrate more towards the reflector 130 at the end after being reflected by the reflective surface 1221, reducing the dispersion during transmission.
[0066] In some other embodiments, the emitting surface and the reflecting surface 131 may both be inclined relative to the second direction Y and arranged in parallel. In this way, since the light emitted by the light source 140 diffuses in multiple directions, the light illuminating the reflecting surface 1221 can also be reflected back to the reflecting surface 1221, reducing light loss. Furthermore, the parallel arrangement of the emitting surface and the reflecting surface 131 can reduce interference when light propagates between the two reflecting surfaces 131, allowing for a smoother light propagation path.
[0067] In some embodiments, the light-emitting component 100 further includes a light-shielding member 150, which is located on the light-emitting side of the light guide 120 and on the side opposite to the reflective surface 131. In some examples, the light-shielding member 150 is fixedly connected within the housing 110. In some examples, both the reflective element 130 and the light-shielding member 150 may be located below the light guide 120, with the reflective element 130 located on the side of the light-shielding member 150 facing the light-emitting side of the light-emitting component 100.
[0068] The light-shielding member 150 is used to block part of the light from the light guide 121, preventing the light from the light guide 121 from scattering from the reflector 130 toward the side of the light-shielding member 150 (i.e., the side opposite to the reflector 131), thus causing light loss. When the light from the light source 140 is diffused by the light guide 121, some of the light will be reflected from the side of the light guide channel close to the reflector 130. In order to ensure that the light is more accurately reflected to the reflector 1221 of the reflector 130 after being refracted by the reflector 1221, the light-shielding member 150 can block the light reflected to the side opposite to the reflector 131, so that more light shines on the reflector 131, reducing the overall light loss and improving the light guiding efficiency.
[0069] In some examples, the material of the light-shielding element 150 is opaque.
[0070] In some examples, the light-shielding element 150 can be a light-shielding plate, a light-shielding cover, a light-shielding cloth, etc. The shape of the light-shielding element 150 can be a regular shape such as square or circle, or an irregular shape such as L-shape. This application does not make specific limitations in this regard.
[0071] In some embodiments, the housing 110 includes a lens 111 and a mounting bracket 112. The lens 111 is mounted on one side of the mounting bracket 112 in a first direction X. The lens 111 includes a first portion 1111 and a second portion 1112. The first portion 1111 is connected to one end of the second portion 1112 in a second direction Y and is located on the side of the second portion 1112 away from the mounting bracket 112 in the first direction X. The first portion 1111 and the mounting bracket 112 define a first mounting space. The light source 140 and the light guide 120 are mounted in the first mounting space. The reflector 130 is connected to the side of the second portion 1112 away from the mounting bracket 112 in the first direction X.
[0072] Specifically, the housing 110 is formed by a lens 111 and a mounting bracket 112. The lens 111 is mounted on one side of the mounting bracket 112 in the first direction X. The lens 111 covers the opening of the mounting bracket 112 and is used to transmit light. The lens 111 includes a first part 1111 and a second part 1112. The first part 1111 of the lens 111 is the upper area enclosed by the lens 111 and the mounting bracket 112. The first part 1111 and the mounting bracket 112 define a first mounting space. The light source 140 is fixedly disposed in the first mounting space and fixedly connected to the mounting bracket 112. The light guide 120 is also disposed in the first mounting space. One end of the light guide 120 is fixedly connected to the mounting bracket 112, and the other end of the light guide 120 covers the light source 140. The light-emitting side of the light source 140 faces the light guide 120. The second part 1112 of the lens 111 and the mounting bracket 112 define a second mounting space. The light shield 150 is installed in the second mounting space and fixedly connected to the mounting bracket 112. The reflector 130 is located on the side of the lens 111 away from the second mounting space and is located on the outside of the lens 111. The reflector 130 is fixedly connected to the vehicle body and is used to absorb the light reflected from the light guide 120 and reflect it evenly. The light guide 120 covers the light source 140 and faces the light-emitting side of the light source 140. It can receive the light emitted by the light source 140 and conduct it in a directional manner, avoiding meaningless scattering of light into the installation space and reducing light loss. The reflector 130 is located outside the lens 111 and fixed to the vehicle body. It can receive the light reflected by the light guide 120, and then reflect the light out after homogenizing it itself, solving the problem of uneven light output from a single light source 140 and ensuring a more uniform lighting effect. The light shield 150 is installed in the second installation space and can accurately block light leakage (such as scattered light in non-target directions) generated by the light source 140 or the light guide 120, ensuring the directionality of the light.
[0073] In some examples, the light source 140 includes a PCB board and an LED lamp. The PCB board is fixedly mounted in the first mounting area of the mounting bracket 112. The PCB board has a reserved circuit interface, which is connected to the vehicle power system via wires to realize the power supply and signal control of the light source 140. The LED lamp is soldered on the preset pads of the PCB board. The light guide 120 is made of transparent PC material. One end of the light guide 120 is fixedly connected to the inside of the mounting bracket 112 by screws, and the other end has an arc-shaped structure that completely covers the light-emitting side of the LED lamp, so as to maximize the reception of the light emitted by the LED lamp. The light guide 120 has microstructure dots inside, which can uniformly diffuse the received light, so that the light is evenly emitted from the light-emitting part of the light guide 120, avoiding the appearance of local bright spots or dark areas.
[0074] In other examples, the light source 140 can also be an incandescent lamp, etc.
[0075] In some examples, the mounting bracket 112 is made of lightweight aluminum alloy, anodized, and has a corrosion-resistant coating. Its dimensions are precisely matched to the vehicle body mounting position to ensure that the housing 110 can be stably fixed to the preset area of the vehicle body.
[0076] In some examples, lens 111 is made of optical-grade material with high light transmittance and excellent resistance to ultraviolet aging and impact, and can withstand long-term high and low temperature cycling in the automotive environment. Lens 111 is embedded in one side of the mounting bracket 112 along the first direction X, completely covering the opening at the top of the mounting bracket 112 to ensure no light leakage.
[0077] In some examples, the second part 1112 of the lens 111 is located below the first part 1111, forming a second mounting space with the bottom crossbeam and side vertical beams of the mounting bracket 112. The second space houses the light shield 150. The light shield 150 is made of black ABS material and is fixed in the inner slot of the mounting bracket 112 by a snap-fit structure. Its surface has a matte finish, which can effectively absorb stray light leaking from the side of the light guide 120, preventing stray light from interfering with the normal operation of other vehicle optical components, while also preventing stray light from reflecting onto the surface of the lens 111 and affecting the overall optical effect.
[0078] In some examples, the reflector 130 is positioned on the outer side of the lens 111 away from the second mounting space (i.e., the side of the lens 111 facing the exterior of the vehicle body). The reflector 130 is made of high-reflectivity aluminum foil and is fixedly connected to the surface of the vehicle body. The shape of the reflector 130 perfectly matches the outer contour of the lens 111, ensuring better reception of light reflected from the light guide 120. The surface of the reflector 130 is polished to uniformly reflect the received light, causing the light to be emitted towards the exterior of the vehicle body at a preset angle, thus meeting the functional requirements of vehicle lighting or signal indication.
[0079] In some embodiments, the light-emitting component 100 further includes a flexible member 160 disposed between the reflector 130 and the second portion 1112.
[0080] Specifically, the flexible component 160 is disposed between the reflector 130 and the second part 1112 of the housing 110. The flexible component 160 can play a role in buffering and compensation. When the vehicle vibrates or the temperature changes cause slight deformation of the component, the flexible component 160 can offset part of the force through its own deformation, so as to avoid damage to the reflector 130 due to rigid collision. At the same time, it can also make up for the slight positional errors that may occur during the assembly process, ensuring that the reflective surface 131 always maintains the correct posture facing the light-emitting side of the light-emitting component 100, and ensuring the stability of light reflection.
[0081] In some examples, there may be one or more flexible components 160, which will not be described in detail here. In some examples, the flexible component 160 may be a rubber component, a latex component, a silicone component, etc.
