Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a vehicle and its side marker light. Background Technology

[0002] With the rapid development of automotive lighting technology and increasingly higher customer demands for more stylish and attractive designs, the requirements for the light-emitting methods and costs of automotive lighting optical systems are also increasing. Currently, to enhance the aesthetics of taillights, side marker lights are added to the sides. Existing side marker lights consist of a light panel and an inner lamp cover. The inner lamp cover displays the logo, and multiple LEDs are positioned on the light panel facing the inner lamp cover. These LEDs directly illuminate the inner lamp cover, displaying the logo. However, this requires a large number of light sources on the light panel, resulting in high costs due to the extensive use of LEDs. Furthermore, the direct illumination of the inner lamp cover by the LEDs creates a significant difference in brightness, leading to a poor visual effect. Utility Model Content

[0003] The main purpose of this utility model is to propose a vehicle and its side marker light, which aims to solve the technical problems of high cost and poor visual effect of existing side marker lights.

[0004] To achieve the above objectives, this utility model proposes a side marker light for a vehicle, comprising:

[0005] Lamp housing;

[0006] An outer lamp cover, which is detachably connected to the lamp housing and forms an installation space;

[0007] An inner lamp cover is disposed within the installation space, and the inner lamp cover and the outer lamp cover are disposed opposite to each other. The inner lamp cover is provided with a pattern mark, and the pattern mark forms a light-emitting area.

[0008] A light-emitting mechanism is disposed within the installation space. The light-emitting mechanism includes a lamp plate and a light guide plate. Both the light guide plate and the lamp plate are disposed on the side of the inner lamp cover away from the outer lamp cover. The light guide plate is disposed opposite to the inner lamp cover, and the lamp plate is disposed at one end near the light guide plate. The light guide plate includes a light-incident surface facing the lamp plate and a light-emitting surface facing the inner lamp cover. A light source for emitting light to the light-incident surface is disposed on the lamp plate. Light entering the light guide plate from the light-incident surface can be emitted from the light-emitting surface to the inner lamp cover and pass through the light-emitting area to exit from the outer lamp cover.

[0009] In one embodiment, the light-emitting surface is provided with a diverging texture, and the diverging texture covers the entire light-emitting surface. Light entering the light guide plate from the light-incident surface is diffused by the diverging texture of the light-emitting surface and then directed toward the inner lampshade.

[0010] In one embodiment, the light-emitting surface completely covers the light-emitting area.

[0011] In one embodiment, a gap exists between the light-emitting surface and the inner lampshade.

[0012] In one embodiment, the area on the inner lampshade other than the light-emitting area is a light-shielding area, the light-shielding area is arranged around the light-emitting area, and the lamp panel is arranged corresponding to the position of the light-shielding area.

[0013] In one embodiment, the lamp panel is provided with a plurality of lamp sources, which are arranged in a row at equal intervals along the extension direction of the light incident surface; a light guide groove is provided on the light incident surface corresponding to the position of each lamp source for the lamp source to extend into.

[0014] In one embodiment, a bracket is connected to the side of the lamp housing facing the mounting space, and a mounting area matching the light guide plate is formed on the side of the bracket away from the lamp housing. The light guide plate is mounted in the mounting area. The lamp plate is fastened to the bracket with screws and is positioned away from the mounting area.

[0015] In one embodiment, the bracket includes a first mounting plate and two second mounting plates disposed at opposite ends of the first mounting plate. The mounting area is formed on the side of the first mounting plate away from the lamp housing. The opposite ends of the inner lamp cover are respectively engaged with the two mounting plates one by one.

[0016] In one embodiment, the outer lampshade has a flange protruding on the side facing the lamp housing, and a groove is formed on the lamp housing corresponding to the position of the flange, the flange extending into the groove and engaging with the groove.

[0017] This utility model also proposes a vehicle that applies the side marker lights as described above.

[0018] The side marker light of this utility model includes a detachably connected lamp housing and an outer lamp cover forming an installation space, which facilitates the subsequent maintenance and replacement of the light-emitting mechanism within the installation space. It also facilitates the replacement of the inner lamp cover with different marking patterns to achieve different lighting effects. The light-emitting mechanism set in the installation space includes a lamp plate and a light guide plate. The light guide plate and the inner lamp cover are arranged opposite each other, with the lamp plate positioned at one end near the light guide plate. The lamp plate is equipped with a light source for emitting light. Some or all of the light can enter the light guide plate from the light-incident surface and propagate along the light guide plate by total internal reflection, making the light more uniform. Light entering the light guide plate shines from its light-emitting surface onto the inner lampshade. The pattern on the inner lampshade forms a light-emitting area, allowing light to pass through this area and exit from the outer lampshade. From an external perspective, the pattern appears to be emitting light. Furthermore, the light is propagated through total internal reflection via the light guide plate, effectively utilizing the light emitted by the lamp source. Even with fewer lamp sources, uniform light distribution can be achieved, allowing light to pass through the entire pattern. This results in more uniform light distribution and reduces uneven brightness caused by direct illumination of the inner lampshade by the lamp source, leading to a better visual effect.

[0028] With the rapid development of automotive lighting technology and increasingly higher customer demands for more stylish and attractive headlight designs, the requirements for the light emission methods and costs of headlight optical systems are also rising. Currently, to enhance the aesthetics of taillights, side marker lights are often added to the sides. Existing side marker lights consist of a light panel and an inner lampshade. The inner lampshade displays the logo, and the light panel has multiple LEDs facing the inner lampshade. These LEDs directly illuminate the inner lampshade to display the logo. However, this requires a large number of light sources on the light panel, resulting in high costs due to the extensive use of LEDs. Furthermore, the direct illumination of the inner lampshade by the LEDs creates a significant difference in brightness, leading to a poor visual effect.

[0029] This utility model proposes a side marker light 100 for a vehicle.

[0030] Please see Figure 1 and Figure 2In one embodiment of this utility model, the side marker light 100 includes a lamp housing 1, an outer lampshade 2, an inner lampshade 3, and a light-emitting mechanism 4. The outer lampshade 2 is detachably connected to the lamp housing 1 and forms an installation space 11. The inner lampshade 3 is disposed within the installation space 11, and the inner lampshade 3 and the outer lampshade 2 are disposed opposite each other. The inner lampshade 3 is provided with a pattern mark, and the pattern mark forms a light-emitting area 31. The light-emitting mechanism 4 is disposed within the installation space 11 and includes a lamp plate 41 and a light guide plate 42. All 41 are located on the side of the inner lampshade 3 away from the outer lampshade 2; wherein, the light guide plate 42 is arranged opposite to the inner lampshade 3, and the lamp plate 41 is arranged at one end near the light guide plate 42. The light guide plate 42 includes a light-incident surface 421 facing the lamp plate 41 and a light-exiting surface 422 facing the inner lampshade 3. The lamp plate 41 is provided with a light source 411 for emitting light to the light-incident surface 421; the light entering the light guide plate 42 from the light-incident surface 421 can be emitted from the light-exiting surface 422 to the inner lampshade 3, and pass through the light-exiting area 31 and be emitted from the outer lampshade 2.

[0031] The side marker light 100 of this utility model includes a detachably connected lamp housing 1 and an outer lamp cover 2 forming an installation space 11, which facilitates subsequent maintenance and replacement of the light-emitting mechanism 4 within the installation space 11. It also allows for easy replacement of the inner lamp cover 3 with different marking patterns, thereby achieving different lighting effects. The light-emitting mechanism 4, located within the installation space 11, includes a lamp plate 41 and a light guide plate 42. The light guide plate 42 and the inner lamp cover 3 are positioned opposite each other. The lamp plate 41 is positioned at one end near the light guide plate 42, and a light source is provided on the lamp plate 41 to emit light. Some or all of the light can enter the light guide plate 42 from the light-incident surface 421 and travel along the light guide plate. The total internal reflection propagation of the light guide plate 42 improves the uniformity of light. The light inside the light guide plate 42 is emitted from the light-emitting surface 422 of the light guide plate 42 to the inner lampshade 3. The pattern mark on the inner lampshade 3 forms the light-emitting area 31, allowing the light to pass through the light-emitting area 31 and be emitted from the outer lampshade 2. From the outside perspective, the pattern mark is emitting light. Moreover, the light is propagated by the total internal reflection of the light guide plate 42, effectively utilizing the light emitted by the light source 411. Even with fewer light sources 411, uniform light distribution can be achieved, thus passing through the entire pattern mark. The light is more uniform, reducing the problem of uneven brightness caused by the light source 411 directly illuminating the inner lampshade 3, resulting in a better visual effect.

[0032] like Figure 1 and Figure 2 As shown, the area defined by the dashed line is the light-emitting area 31. The shape and size of the light-emitting area 31 are determined according to the specific pattern. Figure 1 and Figure 2 The dashed line is for illustrative purposes only and does not specify the shape and size of the light-emitting area 31.

[0033] In one embodiment, the light-emitting surface 422 is provided with a diverging texture, and the diverging texture covers the entire light-emitting surface 422. The light entering the light guide plate 42 from the light-incident surface 421 is diffused by the diverging texture of the light-emitting surface 422 and then directed toward the inner lampshade 3.

[0034] Understandably, the diffused texture can scatter and diffuse the light transmitted from the inside of the light guide plate 42 to the light-emitting surface 422 multiple times, making the light output softer and more uniform, further avoiding uneven light, and making the overall light emission uniformity of the pattern logo on the inner lampshade 3 more uniform, resulting in a better visual effect.

[0035] Furthermore, the area on the inner lamp cover 3 other than the light-emitting area 31 is the light-shielding area 32. The light-shielding area 32 is arranged around the light-emitting area 31, and the lamp panel 41 is arranged in the position corresponding to the light-shielding area 32.

[0036] The light-shielding area 32 blocks light from passing through, ensuring that light can only pass through the light-emitting area 31. This effectively prevents light leakage, making the outline of the logo clearer and the boundaries more distinct, significantly improving the contrast and recognizability of the display, and enhancing the visual effect. In addition, by setting the position of the light panel 41 corresponding to the light-shielding area 32, it effectively prevents the light from the light source 411 from leaking directly out of the light-emitting area 31.

[0037] Furthermore, the light-emitting surface 422 completely covers the light-emitting area 31. Understandably, the fact that the light-emitting surface 422 completely covers the light-emitting area 31 ensures that the light emitted from the light-emitting surface 422 can pass through every position of the light-emitting area 31, avoiding the phenomenon of partial light loss or uneven brightness in some areas of the light-emitting area 31, thereby ensuring that the logo pattern is presented completely and clearly.

[0038] Furthermore, there is a gap between the light-emitting surface 422 and the inner lampshade 3. Understandably, the gap between the light guide plate 42 and the inner lampshade 3 allows air circulation, which helps dissipate heat and reduces the risk of damage due to overheating.

[0039] In one embodiment, a plurality of light sources 411 are provided on the light panel 41, and the plurality of light sources 411 are arranged in a row at equal intervals along the extension direction of the light incident surface 421; a light guide groove is provided on the light incident surface 421 corresponding to the position of each light source 411 for the light source 411 to extend into.

[0040] Understandably, arranging multiple light sources 411 in a row reduces the required number of light sources 411, saving costs. Furthermore, the light guide groove provided on the light-incident surface 421 allows the light sources 411 to extend partially or completely into the light guide groove, shortening the distance between the light source and the light guide plate 42. This significantly reduces the loss of light emitted by the light sources 411, allowing more light energy to enter the light guide plate 42 efficiently from the light-incident surface 421, improving the overall light utilization rate, and making the structure more compact.

[0041] In one embodiment, a bracket 12 is connected to the side of the lamp housing 1 facing the mounting space 11, and a mounting area matching the light guide plate 42 is formed on the side of the bracket 1 away from the lamp housing 1. The light guide plate 42 is mounted in the mounting area; the lamp plate 41 is fastened to the bracket 12 by screws and avoids the mounting area.

[0042] By providing a bracket 12 within the installation space 11, with an installation area on the bracket 12 matching the shape of the light guide plate 42, the light guide plate 42 can be limited and supported, ensuring its accurate position and stable posture within the installation space 11. This effectively prevents the light guide plate 42 from shifting or shaking during vehicle movement, ensuring the stability of light propagation and improving reliability. The bracket 12 simultaneously achieves the positioning and installation of the light guide plate 42 and the fixation of the lamp plate 41, resulting in a simple and compact structure.

[0043] In one embodiment, the bracket 12 includes a first mounting plate 121 and two second mounting plates 122 disposed at opposite ends of the first mounting plate 121. The side of the first mounting plate 121 facing away from the lamp housing 1 forms a mounting area, and the opposite ends of the inner lamp cover 3 are respectively snapped into the two mounting plates. By forming a snap-fit ​​engagement between the two ends of the inner lamp cover 3 and the two second mounting plates 122 of the bracket 12, the inner lamp cover 3 can be securely installed without the need for additional screws, making the operation simple and the disassembly and assembly quick.

[0044] Furthermore, the first mounting plate 121 and the two second mounting plates 122 are integrally formed.

[0045] In one embodiment, the outer lamp cover 2 has a flange 21 protruding on the side facing the lamp housing 1, and a groove is provided on the lamp housing 1 at the position corresponding to the flange 21, with the flange 21 extending into the groove and engaging with the groove.

[0046] The snap-fit ​​structure between the flange 21 and the groove allows for a stable connection between the outer lamp cover 2 and the lamp housing 1 without the need for additional screws or other fasteners. This significantly improves the efficiency of assembling and disassembling the lamp housing 1 and the outer lamp cover 2; furthermore, the flange 21 extending into the groove also provides a certain degree of sealing performance.

[0047] Furthermore, a sealing strip is provided at the flange 21 and the groove. The sealing strip seals the installation space 11, further improving the dustproof and waterproof effect of the installation space 11, ensuring the safe and stable operation of the light-emitting mechanism 4, and improving its service life.

[0048] This utility model also proposes a vehicle that uses the side marker lights 100 as described above. The specific structure of the side marker lights 100 of this vehicle is the same as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
