Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and more specifically, to a vehicle lighting assembly and a vehicle. Background Technology
[0002] Traditional full-width taillights typically consist of "LED + reflector + inner cover containing diffuser" or "LED + rear wall + inner cover". Moreover, they use a circuit board that extends along the left and right sides of the vehicle to densely arrange more than 100 LEDs to meet the light intensity requirements, resulting in a large number of components and high production costs. Utility Model Content
[0003] The problem this invention addresses is: how to reduce the production cost of continuous taillights.
[0004] To solve the above problems, this utility model provides a vehicle lighting assembly and a vehicle.
[0005] In a first aspect, the present invention provides a vehicle lamp assembly, including a lamp cover and a diffuse reflection component, a light guide component, and a light source component disposed within the lamp cover. The lamp cover, the diffuse reflection component, and the light guide component extend along a predetermined direction. The light source component is disposed at one or both ends of the light guide component along the predetermined direction. The light guide component is used to guide the light emitted by the light source component to the diffuse reflection component. The diffuse reflection component covers the light guide component and is used to diffusely reflect the light incident upon it before it exits the lamp cover.
[0006] Optionally, the light guide assembly includes a fixed bracket and a light guide extending along the set direction. Two fixed brackets are respectively disposed at both ends of the light guide along the set direction and are respectively connected to the lampshade. The two ends of the light guide along the set direction are respectively connected to the corresponding fixed brackets. The light source assembly is disposed opposite to the end face of the light guide, and the diffuse reflection assembly is located between the two fixed brackets.
[0007] Optionally, the light source assembly includes a circuit board and a lamp source disposed on the circuit board. The circuit board is connected to the fixed bracket and is spaced apart from the end face of the light guide. The lamp source is located between the light guide and the circuit board and is directly opposite and spaced apart from the end face of the light guide.
[0008] Optionally, the diffuse reflection component includes a mounting bracket and a diffuse reflector. Both the mounting bracket and the diffuse reflector extend along the set direction. The diffuse reflector and the mounting bracket are connected and form a receiving groove extending along the set direction. The light guide passes through the receiving groove and extends out of the receiving groove at both ends. The opposite sides of the light guide are respectively attached to the groove wall of the receiving groove.
[0009] Optionally, the diffuse reflector includes a first reflector and a second reflector. The first reflector, the mounting bracket, and the second reflector are sequentially connected and form the receiving groove. The first reflector and the second reflector are disposed opposite to each other on both sides of the light guide. The second reflector is used to diffusely reflect the light guided onto it by the light guide and then project it onto the first reflector. The first reflector is used to diffusely reflect the light projected onto it and then project it out from the opening of the receiving groove.
[0010] Optionally, the first reflector and the second reflector are in the form of a curved plate structure, the concave surface of the first reflector and the convex surface of the second reflector constitute the reflective surface of the diffuse reflector, and together with the mounting bracket, form the receiving groove.
[0011] Optionally, the first reflector has a plurality of grooves on the side facing the light guide, and the second reflector has a plurality of protrusions on the side facing the light guide.
[0012] The depth of the plurality of grooves decreases from one end of the first reflector connected to the mounting bracket to the end away from the mounting bracket, and / or the height of the plurality of protrusions increases from one end of the second reflector connected to the mounting bracket to the end away from the mounting bracket.
[0013] Optionally, the lampshade includes an outer shell, a bottom shell, and a light-transmitting plate that are connected in sequence and form a receiving cavity. The diffuse reflection component, the light guide component, and the light source component are disposed in the receiving cavity. The bottom shell is used to connect to the vehicle body. The diffuse reflection component is used to diffusely reflect the light incident on it and direct it to the light-transmitting plate and exit the lampshade from the light-transmitting plate.
[0014] Optionally, the headlight assembly further includes a light receiving plate located below the lamp cover and used to receive light emitted from the lamp cover for illumination.
[0015] Secondly, this utility model provides a vehicle including the headlight assembly described above.
[0016] The beneficial effects of this vehicle lamp assembly are as follows: By placing the light source component at one or both ends of the light guide component along its extension direction, and covering the light guide component with a diffuse reflection component, the light emitted by the light source component is guided by the light guide component to the diffuse reflection component, and then diffusely reflected before exiting the lamp cover. In this way, using the light guide component, which reduces light attenuation, as the core light-emitting carrier to propagate the light emitted by the light source component, only a small number of LEDs are needed at the end of the light guide component to ensure sufficient luminous intensity. This significantly reduces the number of light sources in the light source component, thereby reducing the number of components in the vehicle lamp assembly and lowering production costs. Simultaneously, the volume of components such as the circuit board in the light source component can be reduced, facilitating assembly and lightweight design, and simplifying the structure of the circuit board production mold, thus reducing mold development costs. Furthermore, when the vehicle lamp assembly is used as a continuous taillight, the number of components and production costs of the continuous taillight can be reduced. Furthermore, by placing the diffuse reflection component over the light guide component, the light emitted from the light source component can be guided by the light guide component to the diffuse reflection component for diffuse reflection processing as much as possible, thereby improving the utilization rate of the light source and reducing energy consumption. In addition, using the diffuse reflection component to diffuse the light allows the light exiting the lampshade to be evenly diffused, which not only improves the lighting quality but also makes more efficient use of the light source, thereby further reducing unnecessary energy consumption.

[0031] In related technologies, traditional through-type taillights are usually composed of "LED + reflector + inner cover containing diffuser" or "LED + rear wall + inner cover". Moreover, more than 100 LEDs are densely arranged on a circuit board that extends along the left and right direction of the vehicle to ensure that the light intensity meets the usage requirements. This results in a large number of components and high production costs for through-type taillights.
[0032] In view of the problems existing in the above-mentioned related technologies, this utility model provides a vehicle lighting assembly and a vehicle.
[0033] Combination Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a vehicle lamp assembly, including a lamp cover 1 and a diffuse reflection component 2, a light guide component 3 and a light source component 4 disposed within the lamp cover 1. The lamp cover 1, the diffuse reflection component 2 and the light guide component 3 extend along a set direction. The light source component 4 is disposed at one or both ends of the light guide component 3 along the set direction. The light guide component 3 is used to guide the light emitted by the light source component 4 to the diffuse reflection component 2. The diffuse reflection component 2 covers the light guide component 3 and is used to diffusely reflect the light incident on it before it is emitted out of the lamp cover 1.
[0034] It should be noted that the vehicle light assembly in this embodiment can be used as the vehicle's headlights, taillights, and turn signals. The taillights can be a continuous taillight mounted on the tailgate 100, or brake lights, reversing lights, side marker lights, and rear fog lights located at the rear of the vehicle. For ease of description, the vehicle light assembly will be described in detail as a continuous taillight. Since the lamp cover 1 extends along the left and right sides of the vehicle, the setting direction refers to the left and right direction of the vehicle. Figure 1 and Figure 2 The Y-axis direction, referred to as the left-right direction, means that the extension direction of the lampshade 1 (i.e., the length direction of the lampshade 1) is the left-right direction. Correspondingly, the extension direction or length direction of the diffuse reflection component 2 and the light guide component 3 is also the left-right direction.
[0035] Specifically, the lampshade 1, the diffuse reflection component 2, and the light guide component 3 are all elongated structures. The light source component 4 can be located at one end of the light guide component 3 along its length, or at both ends of the light guide component 3 along its length. That is, light can enter the light guide component 3 from one end or from both ends, and then exit from the side of the light guide component 3 onto the diffuse reflection component 2. For example, Figure 2The example shown is that a light source component 4 is set at each end of a long strip-shaped light guide component 3. A diffuse reflection component 2 is placed on the light guide component 3 so that the light emitted by the light source component 4 can be guided by the light guide component 3 to the diffuse reflection component 2 for diffuse reflection processing as much as possible.
[0036] In this embodiment, the light source component 4 can be disposed at one or both ends of the light guide component 3 along its extension direction, and the diffuse reflection component 2 can be placed on the light guide component 3. The light emitted from the light source component 4 is guided by the light guide component 3 to the diffuse reflection component 2, and then diffusely reflected before exiting the lamp cover 1. By using the light guide component 3, which reduces light attenuation, as the core light-emitting carrier to propagate the light emitted from the light source component 4, only a small number of LEDs are needed at the end of the light guide component 3 to ensure sufficient luminous intensity. This significantly reduces the number of light sources in the light source component 4, thereby reducing the number of components in the vehicle lamp assembly and lowering production costs. Simultaneously, the volume of components such as the circuit board 41 in the light source component 4 can be reduced, facilitating assembly and lightweight design, and simplifying the structure of the production mold for the circuit board 41, thus reducing mold development costs. When the vehicle lamp assembly is used as a continuous taillight, the number of components and production costs of the continuous taillight can be reduced. Furthermore, by covering the light guide component 3 with the diffuse reflection component 2, the light emitted from the light source component 4 can be guided by the light guide component 3 to the diffuse reflection component 2 for diffuse reflection processing as much as possible, thereby improving the utilization rate of the light source and reducing energy consumption. In addition, by using the diffuse reflection component 2 to diffuse the light, the light emitted from the lampshade 1 can be evenly diffused, which not only improves the lighting quality but also makes more efficient use of the light source, thereby further reducing unnecessary energy consumption.
[0037] Optionally, combined Figure 2 As shown, the light guide assembly 3 includes a fixed bracket 31 and a light guide 32 extending along a set direction. The two fixed brackets 31 are respectively disposed at both ends of the light guide 32 along the set direction and are respectively connected to the lamp cover 1. The two ends of the light guide 32 along the set direction are respectively connected to the corresponding fixed brackets 31. The light source assembly 4 is disposed opposite to the end face of the light guide 32, and the diffuse reflection assembly 2 is located between the two fixed brackets 31.
[0038] In this optional embodiment, the light guide 32 can be a light guide strip structure, and the light source assembly 4 and the end face of the light guide strip structure are arranged opposite each other along its length. In addition, the light guide 32 can be made of PC material or PMMA material with good light guiding performance to improve the light guiding effect. The fixing brackets 31 are disposed at both ends of the light guide 32, which has a long strip structure, and fix the two ends of the light guide 32. The fixing brackets 31 can be fixed to the lamp cover 1 by means of integral molding, welding or bonding, etc., and the diffuse reflection assembly 2 is located between the two fixing brackets 31. In this way, the light guide component 3 can be installed and fixed inside the lamp cover 1. Moreover, compared with setting a long strip bracket structure to fix the light guide component 32, setting fixed brackets 31 at both ends of the length direction of the light guide component 32 to fix the light guide component 32 not only makes it easier for the diffuse reflection component 2 to be covered on the outside of the light guide component 32 between the two fixed brackets 31, but also simplifies the structure of the light guide component 3 and even the vehicle lamp assembly, further reducing the weight of the vehicle lamp assembly, thereby further reducing production costs.
[0039] Optionally, combined Figure 2 As shown, the two ends of the light guide 32 along a predetermined direction are respectively inserted into corresponding fixing brackets 31. The fixing brackets 31 can be plate-shaped structures perpendicular to the length direction of the light guide 32. Each fixing bracket 31 has fixing holes adapted to the cross-sectional shape of the light guide 32. The two ends of the light guide 32 pass through the fixing holes on two fixing brackets 31 respectively, so that the two ends of the light guide 32 are respectively inserted into the corresponding fixing brackets 31. This achieves the fixing of the light guide 32 by the fixing brackets 31, simplifies the assembly process of the light guide 32, improves assembly efficiency, and facilitates the placement of the light source assembly 4 at the end of the light guide 32, allowing the light emitted by the light source assembly 4 to enter the light guide 32 from the end face of the light guide 32.
[0040] Optionally, combined Figure 6 As shown, the light source assembly 4 includes a circuit board 41 and a light source 42 disposed on the circuit board 41. The circuit board 41 is connected to the fixed bracket 31 and is spaced apart from the end face of the light guide 32. The light source 42 is located between the light guide 32 and the circuit board 41, and is directly opposite to and spaced apart from the end face of the light guide 32.
[0041] In this optional embodiment, the light source 42 disposed on the circuit board 41 can be an LED, and typically there are two to four. A connector can be disposed on the side of the circuit board 41 opposite to the light source 42 to facilitate electrical connection with the driver board to turn the light source 42 on and off. The circuit board 41 and the fixing bracket 31 can be a parallel plate structure. The circuit board 41 and the fixing bracket 31 can be connected by two connecting posts, that is, one end of the two connecting posts is connected to the fixing bracket 31 and the other end is connected to the circuit board 41. The light source 42 is disposed on the side of the circuit board 41 facing the fixing bracket 31, and is directly opposite and spaced apart from the end face of the light guide 32. This ensures that the light emitted by the light source 42 can enter the light guide 32 from the end face of the light guide 32 as much as possible, while avoiding the heat of the light source 42 damaging the light guide 32, thereby improving the service life of the light guide 32.
[0042] Optionally, combined Figure 3 and Figure 4 As shown, the diffuse reflection component 2 includes a mounting bracket 21 and a diffuse reflector 22. Both the mounting bracket 21 and the diffuse reflector 22 extend along a set direction. The diffuse reflector 22 and the mounting bracket 21 are connected and form a receiving groove 23 extending along the set direction. The light guide 32 passes through the receiving groove 23 and extends out of the receiving groove 23 at both ends. The opposite sides of the light guide 32 are respectively attached to the groove wall of the receiving groove 23.
[0043] In this optional embodiment, the diffuse reflector 22 is an elongated strip structure extending along a predetermined direction. The mounting bracket 21 can be a strip structure with the same or approximately the same length as the diffuse reflector 22, or it can be composed of multiple shorter mounting plates. In this case, multiple mounting plates can be spaced apart along the predetermined direction to fix the elongated diffuse reflector 22. Moreover, the diffuse reflector 22 and the mounting bracket 21 form a receiving groove 23 extending along the predetermined direction. The opening of the receiving groove 23 can be a strip-shaped opening extending along the predetermined direction. The light guide 32 passes through the receiving groove 23 along the predetermined direction and extends out of the receiving groove 23. The length of the light guide 32 can be greater than the length of the diffuse reflector 22, and both ends of the light guide 32 extend beyond the two ends of the diffuse reflector 22 to facilitate cooperation with the light source assembly 4. At the same time, the two ends of the light guide 32 perpendicular to the predetermined direction are respectively attached to the groove wall of the receiving groove 23, so that the diffuse reflector assembly 2 can be fixed as a whole on the light guide 32. In this way, there is no need to connect the mounting bracket 21 to the lampshade 1 to fix the diffuse reflection component 2, and there is no need to set an additional connection structure on the lampshade 1 to connect the mounting bracket 21. This simplifies the structure of the lampshade 1 and facilitates the modular design of the lampshade 1.
[0044] Optionally, combined Figure 3 and Figure 4As shown, the diffuse reflector 22 includes a first reflector 221 and a second reflector 222. The first reflector 221, the mounting bracket 21, and the second reflector 222 are connected in sequence and form a receiving groove 23. The first reflector 221 and the second reflector 222 are arranged opposite to each other on both sides of the light guide 32. The second reflector 222 is used to diffusely reflect the light guided by the light guide 32 onto the first reflector 221. The first reflector 221 is used to diffusely reflect the light onto it and then emit it from the opening of the receiving groove 23.
[0045] In this optional embodiment, the mounting bracket 21 can be a plate-like structure. The first reflector 221 and the second reflector 222 can be connected to opposite ends of the mounting bracket 21, and the space enclosed by the first reflector 221, the mounting bracket 21, and the second reflector 222 constitutes a receiving groove 23. In this way, the second reflector 222 can reflect the light emitted from the light guide 32 that has not reached the first reflector 221 back to the first reflector 221, and after diffuse reflection by the first reflector 221, the light will exit the receiving groove 23 through the opening of the receiving groove 23, and then be emitted through the lampshade 1, thereby improving the utilization rate of the light source and reducing energy consumption.
[0046] Optionally, combined Figure 3 and Figure 4 As shown, the first reflector 221 and the second reflector 222 are curved plate-like structures. The concave surface of the first reflector 221 and the convex surface of the second reflector 222 constitute the reflective surface of the diffuse reflector 22 and together with the mounting bracket 21 form a receiving groove 23.
[0047] In this optional embodiment, the first reflector 221 and the second reflector 222 are curved plate-like structures, wherein the bending directions of the first reflector 221 and the second reflector 222 are approximately the same. The first reflector 221 is recessed outward from the receiving groove 23, and the second reflector 222 is recessed inward from the receiving groove 23. That is, the concave surface of the first reflector 221 is located inside the receiving groove 23, and the concave surface of the second reflector 222 is located outside the receiving groove 23. Moreover, the ends of the first reflector 221 and the second reflector 222 away from the mounting bracket 21 respectively form the opening of the receiving groove 23. Specifically, for example, one end of the first reflector 221 may be located above the light guide 32 and connected to the mounting bracket 21, and the other end of the first reflector 221 may be bent obliquely downward to below the light guide 32. One end of the second reflector 222 may be located below the light guide 32 and connected to the mounting bracket 21, and the other end of the second reflector 222 may be bent obliquely downward to be flush with the other end of the first reflector 221. In this way, the first reflector 221 covers the light-emitting side of the light guide 32 (the side of the light guide 32 away from the mounting bracket 21) and the second reflector 222, so as to simultaneously receive the light emitted from the light guide 32 and the light reflected by the second reflector 222, and reflect the light incident on it toward the slot.
[0048] Furthermore, the first reflector 221 and the second reflector 222 are respectively snapped into the mounting bracket 21. In this way, rapid assembly is achieved while ensuring a secure connection.
[0049] Optionally, combined Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the first reflector 221 has a plurality of grooves 2211 on the side facing the light guide 32, and the second reflector 222 has a plurality of protrusions 2221 on the side facing the light guide 32.
[0050] The groove depth of the plurality of grooves 2211 decreases from one end of the first reflector 221 connected to the mounting bracket 21 to the end away from the mounting bracket 21, and / or the protrusion height of the plurality of protrusions 2221 increases from one end of the second reflector 222 connected to the mounting bracket 21 to the end away from the mounting bracket 21.
[0051] In this optional embodiment, by providing a plurality of grooves 2211 on the side of the first reflector 221 facing the light guide 32 and providing a plurality of protrusions 2221 on the side of the second reflector 222 facing the light guide 32, the reflective surfaces of the first reflector 221 and the second reflector 222 are rough surfaces with uneven surfaces, so as to realize diffuse reflection of light by scattering light in various directions on the rough surface. Compared with the method of applying diffuse reflection material to the reflective surface of the reflector to achieve diffuse reflection, the coating process and production cost can be reduced and the production efficiency can be improved. Furthermore, by decreasing the groove depth of the multiple grooves 2211 from one end of the first reflector 221 connected to the mounting bracket 21 to the end away from the mounting bracket 21, that is, decreasing the groove depth along the direction close to the groove opening, it is ensured that the light irradiated on the first reflector 221 can exit the lampshade 1 according to a preset route; by increasing the protrusion height of the multiple protrusions 2221 from one end of the second reflector 222 connected to the mounting bracket 21 to the end away from the mounting bracket 21, that is, decreasing the groove depth along the direction close to the groove opening, it is ensured that the light irradiated on the second reflector 222 can be reflected onto the first reflector 221 and exited outside the lampshade 1 after diffuse reflection by the first reflector 221.
[0052] Furthermore, combined Figure 7 As shown, multiple grooves 2211 are distributed in multiple rows and columns and connected without gaps. In this way, the roughness of the reflecting surface of the first reflector 221 is increased, thereby improving the diffuse reflection effect of the first reflector 221.
[0053] Furthermore, combined Figure 8 As shown, the protrusions 2221 are elongated strip structures extending along a predetermined direction. Multiple protrusions 2221 are connected without gaps along the direction from one end of the second reflector 222 connected to the mounting bracket 21 to the end away from the mounting bracket 21. In this way, the roughness of the reflective surface of the second reflector 222 is increased, thereby improving the diffuse reflection effect of the second reflector 222.
[0054] Optionally, combined Figure 3 and Figure 4 As shown, the lampshade 1 includes an outer shell 11, a bottom shell 12, and a light-transmitting plate 13 that are connected in sequence and form a receiving cavity 14. The diffuse reflection component 2, the light guide component 3, and the light source component 4 are disposed in the receiving cavity 14. The bottom shell 12 is used to connect to the vehicle body. The diffuse reflection component 2 is used to diffusely reflect the light incident on it and then direct it to the light-transmitting plate 13 and exit the lampshade 1 from the light-transmitting plate 13.
[0055] In this optional embodiment, the outer shell 11 constitutes the styling component of the lamp cover 1, adapted to the vehicle body styling. The bottom shell 12 can be detachably fixed to the vehicle body using fasteners such as screws, thereby achieving the mounting and fixing of the lamp assembly on the vehicle body. Specifically, for a through-type taillight, the bottom shell 12 is connected to the sheet metal of the tailgate 100. The light-transmitting plate 13 of the lamp cover 1 faces the slot 23 of the diffuse reflection component 2. The position of the light-transmitting plate 13 can be adaptively designed according to the light emission angle of the lamp assembly. For example, for a through-type taillight, the light-transmitting plate 13 can be positioned at the lower end of the lamp cover 1 to achieve downward light emission; for a headlight, the light-transmitting plate 13 can be positioned at the front end of the lamp cover 1 to achieve forward light emission. In this way, by setting the lamp cover 1 to include three parts: the outer shell 11, the bottom shell 12, and the light-transmitting plate 13, on the one hand, it is possible to ensure that the lamp cover 1 can meet the appearance requirements of different vehicle models by only making adaptive adjustments to the outer shell 11, which constitutes the styling parts of the lamp cover 1; on the other hand, it is possible to make adaptive adjustments to the setting position of the light-transmitting plate 13 according to the light emission angle of the vehicle lamp assembly to ensure that the vehicle lamp assembly meets the lighting requirements, so that the entire lamp cover 1 does not need to be redesigned, which facilitates the modular design of the vehicle lamp assembly.
[0056] Optionally, combined Figure 1 and Figure 5 As shown, the vehicle headlight assembly may also include a light receiving plate 5, which is located below the lamp cover 1 and is used to receive light emitted from the lamp cover 1 for illumination. The light-transmitting plate 13 in the lamp cover 1 is located at the lower end of the lamp cover 1, and the light receiving plate 5 can be fixed to the tailgate 100 and is located below the lamp cover 1. In this way, light exits the lamp cover 1 from the light-transmitting plate 13 at the lower end of the lamp cover 1 and illuminates the light receiving plate 5. The light receiving plate 5 reflects the light emitted from the lamp cover 1 into the eyes of the wearer, thus achieving the illumination function of a continuous taillight.
