[0031] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] The following refers to Figures 1 - 3Describe the vehicle exterior trim component 100 according to an embodiment of the present utility model.

[0033] The vehicle exterior trim component 100 according to an embodiment of the present utility model is referred to Figure 1 and Figure 2 and includes: an exterior trim panel 50 and a lighting component 10. At least a part of the area of the exterior trim panel 50 is a light-transmitting area 51, and the lighting component 10 is arranged inside the exterior trim panel 50.

[0034] It can be understood that as the name implies, the vehicle exterior trim component 100 is arranged on the outer surface of the vehicle body. For example, it can be an A-pillar trim panel, a B-pillar trim panel, a C-pillar trim panel, or a vehicle door outer panel, a vehicle body outer panel, etc., which is not limited here. Thus, when the lighting component 10 is lit, the light-transmitting area 51 of the exterior trim panel 50 forms a lighting area, and the lighting area can be observed from the outside of the vehicle. Thereby, a lighting element is obtained on the vehicle body surface, and the vehicle styling has a more technological sense, improving the appearance quality.

[0035] When the lighting area formed by the light-transmitting area 51 of the exterior trim panel 50 is large or the brightness is high, the position of the vehicle body can be presented at night or in a dim environment, and even the outline of the vehicle body can be clearly presented, improving the convenience and safety of use.

[0036] In addition, in some solutions, the lighting component 10 of the vehicle exterior trim component 100 can also be designed functionally. For example, it can be used as a warning light device to warn the driver and passengers about vehicle problems, such as the door not being closed, the fuel running out, etc. According to the design of the lighting component 10, different warning contents can be generated by displaying different colors, or the driver and passengers can be warned by the flashing of the light. Another example is that it can be used as a stock display device. For example, the lighting area of the lighting component 10 is controllable, and the remaining power of the vehicle can be reminded to the driver and passengers by different lighting areas. Designed in this direction, the appearance and function of the vehicle exterior trim component 100 can be diversified.

[0037] In this application, as Figure 2 and Figure 3 shown, the lighting component 10 includes: a light guide plate 2, a light source component 1 that emits light rays towards the light guide plate 2, at least a part of the light guide plate 2 is arranged corresponding to the light-transmitting area 51, and the light source component 1 is a flexible light strip.

[0038] It can be understood that the light guide plate 2 is a material plate known in the prior art, made of a material with an extremely high refractive index and non-light-absorbing properties, such as an acrylic plate. After the optical-grade acrylic plate absorbs the light emitted from the light source component 1, it reflects multiple times within the optical-grade acrylic plate, diffuses to various angles, and then emits from the front surface of the light guide plate 2 and passes through the light-transmitting area 51 of the exterior trim plate 50 to form a uniform surface light. This method of forming surface light through the light guide plate 2 has high luminous efficiency and low power consumption under the condition of the same luminous brightness per unit area. Such a design does not require the light source component 1 to be too large in size. A slender light strip can be used, and a certain-width surface light can be obtained through the light guide plate 2, which is beneficial to the thin and light design of the lighting component 10.

[0039] Moreover, for the structure of the vehicle body exterior component 100 on the vehicle body exterior surface, the light source needs to be set as a surface light with a certain width to make the luminous area presented externally more prominent. In particular, the A-pillar trim plate, B-pillar trim plate, and C-pillar trim plate are all strip-shaped plates. The slender light source obtained by using the flexible light strip for the light source component 1 can obtain a strip-shaped luminous area with a certain width through the light guide plate 2, which is easier to be arranged on these plates.

[0040] The vehicle body exterior component 100 obtained in this way is convenient to control the overall shape into a thin plate shape. When the vehicle body exterior component 100 is assembled to the vehicle body, the vehicle body exterior component 100 can almost directly replace the original vehicle body exterior trim plate, and the skeleton plate inside the vehicle body exterior trim plate does not need to be deformed. In this way, the application cost of this design of the present application can be greatly reduced.

[0041] In the present application, setting the light source component 1 as a flexible light strip has many advantages:

[0042] First, the vehicle body exterior component 100 is the outer contour plate of the vehicle body. To match the overall shape, usually the outer contour plate of the vehicle has a certain curvature. Setting the light source component 1 as a flexible light strip does not require considering the curvature of the vehicle body shape during processing. After assembly, the shape of the flexible light strip can be adapted to the shapes of the exterior trim plate 50 and the light guide plate 2. This reduces the processing difficulty and cost, and also reduces the problems of inability to assemble and high scrap rate caused by insufficient processing accuracy.

[0043] Second, the vehicle body exterior component 100 is the outer contour plate of the vehicle body, and the outer contour plate of the vehicle body usually bears external forces first and undergoes buckling during a vehicle collision. Setting the light source component 1 as a flexible light strip helps to absorb external stress, and the vehicle can still work normally during vibration and collision, improving the reliability.

[0044] Third, compared with the scheme of setting the light source component 1 as a light-emitting film, etc., the scheme of using a flexible light strip for the light source component 1 in the present application has a mature production process, low cost, and the flexible light strip has a waterproof function. The vehicle body exterior component 100 of the present application has good luminous stability, high reliability, and long service life.

[0045] Optionally, the light source component 1 can adopt a light-emitting silica gel strip known in the prior art, and its structure will not be described in detail here. Of course, the silica gel tube in the light-emitting silica gel strip can also be replaced with other flexible materials, which is not limited here.

[0046] In some embodiments, as Figure 3 shown, the light-emitting component 10 further includes: a light-blocking plate 3 connected to the side of the light guide plate 2 away from the exterior trim plate 50, and the light source component 1 is installed on the light-blocking plate 3. The light-blocking plate 3 can not only serve as an installation support structure for the light source component 1 and the light guide plate 2, but also block the light emitted towards the interior of the vehicle, avoiding light leakage inside the vehicle and affecting the sight and perception of the driver and passengers.

[0047] Specifically, as Figure 3 shown, a light-receiving cavity 41 is formed between the light-blocking plate 3 and the light guide plate 2, and the surface of the light-blocking plate 3 facing the light-receiving cavity 41 is a reflective surface 31. Since the light guide plate 2 itself has strong light guiding properties, when light is emitted from the light guide plate 2 into the light-receiving cavity 41, the reflective surface 31 of the light-blocking plate 3 reflects the light back to the light guide plate 2, reducing light energy loss and increasing the illumination brightness of the light-emitting area presented externally.

[0048] Here, forming the light-receiving cavity 41 between the light-blocking plate 3 and the light guide plate 2 facilitates installing the light source component 1 on the light-blocking plate 3 or arranging it in the light-receiving cavity 41, so that the light emitted by the light source component 1 can be directed towards the light guide plate 2 as much as possible, further reducing light loss.

[0049] Specifically, on the surfaces of the light-blocking plate 3 and the light guide plate 2 facing each other, one is provided with an installation protrusion 42, and the other is provided with an installation groove 43 that cooperates with the installation protrusion 42. In this way, the light-blocking plate 3 and the light guide plate 2 can be snapped together, facilitating positioning and connection methods. Moreover, it can avoid connecting components such as connecting screws and prevent the loosening of the connecting components during vibration. The number and shape of the installation protrusions 42 are not specifically limited here.

[0050] Specifically, the installation protrusion 42 is strip-shaped, which facilitates forming the light-receiving cavity 41 between the two installation protrusions 42.

[0051] Optionally, the installation protrusion 42 is strip-shaped, the installation protrusion 42 is arranged adjacent to the edge of the light-blocking plate 3, the installation protrusion 42 includes at least two, and the light source component 1 is arranged on the installation protrusion 42. In this way, the light-blocking plate 3 is thicker at the installation protrusion 42, and the structural strength here can still be ensured after arranging the light source component 1, reducing the risk of breakage at the installation position of the light source component 1.

[0052] In addition, by arranging the light source component 1 on the installation protrusion 42 and providing an installation groove 43 on the corresponding light guide plate 2, the light source component 1 is equivalent to being inserted into the installation groove 43, facilitating the light source component 1 to directly emit light into the light guide plate 2 and reducing light loss.

[0053] In some specific embodiments, a scattering texture surface 21 is formed on the surface of the light guide plate 2 facing the light blocking plate 3. In this way, the scattering texture surface 21 can be utilized to further disperse the reflection angle of the light, making the light distribution more uniform when it exits the light guide plate 2 and improving the brightness uniformity of the light emitting area. Specifically, the scattering texture surface 21 includes a plurality of convex surfaces and concave surfaces, which can diverge and equalize the reflected light.

[0054] Optionally, the light blocking plate 3 is an integrally injection molded part, and the light source component 1 is fixedly connected to the light blocking plate 3 through injection molding of the light blocking plate 3. In this way, the connection between the light source component 1 and the light blocking plate 3 is firm and reliable, avoiding the probability of the light source component 1 loosening from the light blocking plate 3 during vehicle driving and vibration. Of course, when set in this way, the light emitting end of the light source component 1 is still exposed on the side of the light blocking plate 3 facing the light guide plate 2.

[0055] With such a setting, the non-light emitting components of the light source component 1 can be buried in the light blocking plate 3, which not only improves the aesthetics but also can improve the protection environment of these non-light emitting components against water and gas.

[0056] Furthermore, as Figure 3 shown, the wire harness of the light source component 1 is located on the side of the light blocking plate 3 away from the light guide plate 2. In this way, the light blocking plate 3 is used to block the wire harness, facilitating the wiring of the wire harness.

[0057] In some embodiments, a film layer covering at least the light transmissive area 51 is provided on the exterior trim panel 50. Here, the position of the film layer can be on the outer side surface of the exterior trim panel 50 or on the inner side surface of the exterior trim panel 50. The film layer is provided such that when the light source component 1 is turned off, the film layer blocks the light transmissive area 51, preventing external personnel from seeing the internal light emitting component 10 structure through the light transmissive area 51. When the light source component 1 is turned on, the film layer transmits light, making the light transmissive area 51 a light emitting area.

[0058] Here, the structural type of the film layer can be flexibly selected. For example, the film layer can be an ink layer. It can be understood that when the ink layer is relatively thin, the density of the particles in the layer is not high and there are pores between the particles. When the light source component 1 is turned off, on the appearance of the exterior trim panel 50 at the light transmissive area 51, what is presented is the brightness and color of the film layer under external light. When the light source component 1 is turned on, the internal light passes through the pores of the micro-particles, and what is presented on the exterior trim panel 50 at the light transmissive area 51 is a light emitting area. Here, neither the color nor the shape of the film layer is limited. For example, the film layer is black that is the same as the body color.

[0059] Optionally, the film layer is a printed layer or can also be a coating, etc. Patterns can be printed in segments to serve as the film layer.

[0060] For another example, the film layer is a photochromic layer, so that when the light source member 1 is turned off and on, the color presented on the appearance of the exterior trim panel 50 at the light-transmitting area 51 is different. Here, the photochromic layer can adopt the photochromic layer structure known in the prior art, and its principle will not be elaborated.

[0061] Of course, the exterior trim panel 50 in the present application may not be provided with a film layer. For example, the light-transmitting area 51 is covered from the inside by the light guide plate 2. For another example, the light-transmitting area 51 of the exterior trim panel 50 is subjected to a matte treatment.

[0062] Optionally, the exterior trim panel 50 may be a plastic plate, and in some solutions, it is not excluded that the exterior trim panel 50 is made into a sheet metal part or a glass part, etc. Alternatively, the exterior trim panel 50 can be obtained by IML process.

[0063] In some embodiments, the exterior trim panel 50 is elongated, and there are multiple light-emitting components 10, which are arranged at intervals along the extending direction of the exterior trim panel 50. The multiple light-emitting components 10 can be independently switched on and off to form a power display bar. In this way, the driver and passengers can observe the remaining power through the light-emitting components 10 outside the vehicle without entering the vehicle to view.

[0064] Specifically, a plurality of light-transmitting areas 51 can be provided on the exterior trim panel 50, and each light-transmitting area 51 corresponds to a light-emitting component 10. Or a plurality of light-emitting components 10 are correspondingly arranged in one light-transmitting area 51.

[0065] Specifically, the controller of the light-emitting component 10 is communicatively connected to the vehicle control system. For example, signals can be directly exchanged through wires, or signals can be exchanged wirelessly. For example, communication and interaction occur between the PCB board of the light-emitting component 10 and the vehicle ECU, and the amount of power is presented through 4 light-emitting areas.

[0066] The vehicle according to the embodiment of the present invention includes a body exterior trim component 100 according to the embodiment of the present invention. The body exterior trim component 100 is provided on at least one of the A-pillar, B-pillar, and C-pillar of the vehicle, so as to achieve the body lighting effect of the vehicle, which is not only beautiful but also can serve as a functional component to play a reminder role.

[0067] Specifically, the exterior trim panel 50 can be used as the decorative outer panel of the vehicle A-pillar, and the light-emitting component 10 is installed between the exterior trim panel 50 and the sidewall sheet metal 60.

[0068] Other components of the vehicle according to the embodiment of the present invention, such as the engine and other structures, as well as operations, are known to those of ordinary skill in the art and will not be described in detail here.

[0070] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model, and the scope of the present utility model is defined by the claims and their equivalents.
