Description

Technical Field

[0001] This application relates to the field of vehicle signal system lighting fixtures, and more specifically, to a vehicle signal light guide structure and a vehicle. Background Technology

[0002] A light guide is a structural component that directs light emitted from an LED from a PCB board to the front panel or the desired light-emitting location. This component is typically made of PC or PMMA material and has excellent light-guiding properties.

[0003] Light guides are already a common light-emitting form for headlights and taillights. Due to their low cost and rich design options, they are widely recognized by customers. Light guides have evolved from the original single strip to L-shaped, C-shaped, and O-shaped, and their length has increased from 300mm to 1500-2000mm. Paired with uniformly diffused external light distribution lenses, they can meet various design requirements.

[0004] Traditionally, the light guide is used with light entering from one end. The energy is most concentrated at the entrance end, often resulting in more bright spots. This is typically mitigated by adding supports or ribs outside the visible area to reduce the impact of these bright spots on the appearance, or by using a darkened texture to mask them, thus achieving a better lighting effect. This method is more practical for short light guides. However, when the light guide is longer, with light entering from both ends, or when there are multiple segments in C-type or O-type light guides, there will be multiple entrance ends. If the joints cannot be completely blocked, bright spots at the joints are unavoidable, significantly affecting the lighting effect. Summary of the Invention

[0005] The purpose of this application is to provide a vehicle signal light guide structure and vehicle, which can effectively improve the bright spots at the connection of the light guide and radiation structure and improve the uniformity of lighting.

[0006] The embodiments of this application are implemented as follows:

[0007] In a first aspect, this application provides a vehicle signal light guide structure, including: a light guide assembly and a sheath assembly; wherein the sheath assembly is detachably disposed on the light guide assembly, and the sheath assembly is made of a light-transmitting material.

[0008] In one embodiment, the light guide assembly includes: a first light guide and a second light guide, wherein one end of the second light guide is connected to the first light guide; the sheath assembly includes: a first sheath and a second sheath; wherein the first sheath is detachably fitted onto the first light guide; and the second sheath is connected to the first sheath at one end and is detachably fitted onto the second light guide.

[0009] In one embodiment, the first sheath has a first slot; the second sheath has a second slot; the first slot and the second slot are connected.

[0012] In one embodiment, the light guide assembly is provided with a limiting post, and the sheath assembly is provided with a limiting groove. The limiting post passes through the limiting groove to fix the light guide assembly.

[0013] In one embodiment, the limiting post is snapped together with the first slot or the second slot to fix the sheath assembly to the light guide assembly.

[0014] In one embodiment, the length of the first sheath is less than or equal to the length of the first optical guide; the length of the second sheath is less than or equal to the length of the second optical guide.

[0015] Secondly, this application provides a vehicle, including a signal light body and a plurality of the above-mentioned vehicle signal light guiding structures, wherein the vehicle signal light guiding structures are disposed in the signal light body.

[0016] In one embodiment, the vehicle further includes: an external light distribution mirror, an LED circuit board assembly, and a heat sink; the external light distribution mirror is connected to the signal light body; the LED circuit board assembly is disposed in the signal light body for emitting light; and the heat sink is disposed in the signal light body.

[0017] The advantages of this application compared to the prior art are:

[0018] Energy is concentrated at the light-inlet emitter end, which easily produces bright spots. This application installs a protective sleeve assembly at the connection of the light-inlet emitter end. The protective sleeve assembly can effectively reduce bright spots and block excess bright spots, so that the uniformity of the lighting reaches the best state and there will be no defects such as local dark areas or bright spots. Thus, it can better meet the uniformity requirements of automotive signal lights. Attached Figure Description

Detailed Implementation

[0027] The terms “first,” “second,” “third,” etc., are used only for distinguishing descriptions and do not indicate a sequence number, nor should they be interpreted as indicating or implying relative importance.

[0028] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of this application, it should be noted that the terms "inner", "outer", "left", "right", "upper", "lower", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] In the description of this application, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” shall be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; as a direct connection or an indirect connection through an intermediate medium; or as a connection within two components.

[0031] The technical solution of this application will now be clearly and completely described with reference to the accompanying drawings.

[0032] Please refer to Figure 1 This is a schematic diagram of the structure of a vehicle 1 shown in an embodiment of this application. A vehicle 1 includes a signal light body 11 and a plurality of vehicle signal light guide structures 12, the vehicle signal light guide structures 12 being disposed within the signal light body 11.

[0033] Vehicle 1 also includes an external light distribution lens 13 and an LED circuit board assembly 14. The external light distribution lens 13 is connected to the signal light body 11, and the LED circuit board assembly 14 is located inside the signal light body 11 to emit light, allowing the light to propagate along the vehicle signal light guide structure 12 to the desired light-emitting position. LED luminous flux refers to the amount of light emitted per unit time, and luminous flux is directly proportional to the energy required for optics. Depending on the luminous flux, it is optional whether to install a heat sink 15 inside the signal light body 11. When the luminous flux is higher, the driving current will be greater, there will be more control components, and the overall heat will increase. However, the space is often fixed, i.e., the heat dissipation area is constant, so it is necessary to install a heat sink 15 inside the signal light body 11. When the luminous flux is low, it is not necessary to install a heat sink 15.

[0034] The signal light body 11 may include one or more of the following: headlights, taillights, or turn signals. When the signal light body 11 is a headlight, it is installed at the front of the vehicle 1 for illuminating and controlling the high and low beams; when the signal light body 11 is a taillight, it is installed at the rear of the vehicle 1 for indicating the braking signal; when the signal light body 11 is a turn signal, it is installed on the body of the vehicle 1, rearview mirrors, A-pillars, etc., to indicate that the vehicle 1 is turning.

[0035] Please refer to Figure 2 This is a schematic diagram of a vehicle signal light guide structure 12 according to an embodiment of this application. A vehicle signal light guide structure 12 includes: a light guide assembly 100 and a sheath assembly 200; wherein, the sheath assembly 200 is detachably disposed on the light guide assembly 100.

[0036] The sheath assembly is made of a light-transmitting material with a transmittance range of 1%-99%. When the light transmitted by the light guide assembly 100 is directed to the sheath assembly 200, the brightness of the light transmitted by the light guide assembly 100 will decrease after passing through the sheath assembly 200, and the original bright spots will be weakened, thereby improving uniformity.

[0037] The sheath assembly 200 can be made of different colors and materials, and different color codes of the sheath assembly 200 correspond to different transmittance. In one embodiment, the sheath assembly 200 can be made of polycarbonate (PC) material, with a transparent gray color and model number LS2_71127 or LS2_GY3A578T, or with a bright red color and model number 2407 321390. The transmittance is not only related to the thickness of the sheath assembly 200, but also to the LED luminous intensity, luminous flux, and the material of the sheath assembly 200. A change in any of these influencing factors will cause a change in transmittance. Different colors, thicknesses, and lengths of the sheath assembly 200 can be selected to suit different bright spot intensities and areas.

[0038] The light guide assembly 100 includes a first light guide 110 and a second light guide 120. The first light guide 110 is in a straight line shape, and one end of the second light guide 120 is connected to the first light guide 110. One end of the second light guide 120 can be located in the middle of the first light guide 110, forming a T-shaped structure. The sheath assembly 200 includes a first sheath 210 and a second sheath 220. The first sheath 210 is detachably fitted onto the first light guide 110. One end of the second sheath 220 is connected to the first sheath 210 and is detachably fitted onto the second light guide 120. The shape of the sheath assembly 200 is consistent with the shape of the light guide assembly 100.

[0039] In this embodiment, the first sheath 210 has a "C-shaped" structure, the second sheath 220 has two "semi-circular" structures, and the sheath assembly 200 is sleeved on the outside of the incident end connection of the light guide assembly 100.

[0040] The first sheath 210 has a first slot 211; the second sheath 220 has a second slot 221; the first slot 211 and the second slot 221 are connected.

[0041] During the operation, along the direction of the first slot 211 and the second slot 221, a gap of a certain size is opened up and down. First, one end of the first light guide 110 is inserted into the space of the "C-shaped" structure of the first sheath 210. Relying on the deformation of the light guide component 100 itself, the light guide component 100 is inserted into the sheath component 200 along the direction of the slot opening parallel to the first slot 211 and the second slot 221, so that the sheath component 200 fits the light guide component 100. Conversely, the light guide component 100 can be removed and replaced in the same way to achieve disassembly.

[0042] The first sheath 210 is provided with a first top rib 212 for fixing the first light guide 110; the second sheath 220 is provided with a second top rib 222 for fixing the second light guide 120. In this embodiment, the first top rib 212 can be connected with the second top rib 222 to form an integral structure, which facilitates the simultaneous fixing of the first light guide 110 and the second light guide 120.

[0043] In this embodiment, the second sheath 220 is also provided with a third top rib 223, which is used to fix the second light guide 120 and prevent the second light guide 120 from moving inside the second sheath 220.

[0044] The light guide assembly 100 is provided with a limiting post 130, and the sheath assembly 200 is provided with a limiting groove 230. The limiting post 130 passes through the limiting groove 230 and is used to fix the light guide assembly 100. The limiting post 130 can be set at any position on the first light guide 110, and the limiting groove 230 is set at the corresponding position on the first sheath 210. The limiting post 130 is connected to the first groove 211 or the second groove 221 by a snap-fit ​​connection, so as to fix the light guide assembly 100 by the sheath assembly 200.

[0045] In one embodiment, the limiting post 130 can be one or more, and the number and position of the limiting groove 230 must be consistent with the number and position of the limiting post 130.

[0046] The length of the first sheath 210 is less than or equal to the length of the first light guide 110; the length of the second sheath 220 is less than or equal to the length of the second light guide 120. The size of the bright spot is related to the connection position of the light guide at the emission end and the light guide structure. The length of the sheath assembly 200 can be adjusted according to the actual size of the bright spot. The length of the sheath assembly 200 generally does not exceed the length of the light guide assembly 100.

[0047] In one embodiment, the inner diameter of the sheath assembly 200 can be equal to the diameter of the light guide assembly 100, so that the light guide assembly 200 can be fixed inside the sheath assembly 200, or the inner diameter of the sheath assembly 200 is larger than the diameter of the light guide assembly 100, and then the light guide assembly 100 is reinforced and fixed in conjunction with the first top rib 212, the second top rib 222 and the third top rib 223.

One end of the second light guide 120 is connected to the first light guide 110, and one end of the second light guide 120 is located in the middle of the first light guide 110. The other end of the second light guide 120 is bent and raised to form a "T" shape. The shape of the sheath assembly 200 is consistent with the shape of the light guide assembly 100, and it is sleeved on the outside of the incident connection of the light guide assembly 100. Among them, the first sheath 210 has a first slot 211; the second sheath 220 has two symmetrical second slots 221.

[0050] During the operation, the second sheath 220 is pried open upward along the second slot 221, and the first light guide 110 is moved into the first slot 211 along the slot direction parallel to the second slot 221. The first light guide 110 extends into the first sheath 210 by its own deformation, so that the sheath assembly 200 fits the light guide assembly 100.
