[0027] The embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments of the present application are mainly for illustrating possible implementation manners of the technical solutions of the present application and should not be construed as limitations on the technical solutions of the present application. In this specification, the same or similar components are denoted by the same or similar reference numerals.

[0028] Figure 1 It is a schematic structural diagram of a motor vehicle 200 provided by an embodiment of the present application; Figure 2 For Figure 1 Partial enlarged view C of the motor vehicle 200 shown; Figure 3 For Figure 1 Schematic diagram of the A-A cross-section of the motor vehicle 200 shown; Figure 4 For Figure 3 Partial enlarged view D of the motor vehicle 200 shown; Figure 5 For Figure 1 Schematic structural diagram of the lighting assembly 100 in the motor vehicle 200 shown; Figure 6 For Figure 5 Front view of the lighting assembly 100 shown.

[0029] As Figures 1-6 Shown, an embodiment of the present application provides a lighting assembly 100 and a motor vehicle 200 including the lighting assembly 100.

[0030] The lighting assembly 100 includes a lens assembly 10. The lens assembly 10 includes a first lens part 11 and a second lens part 12. The first lens part 11 and the second lens part 12 are injection-molded together, and the first lens part 11 has an injection-molding positioning hole 11a.

[0031] The lens assembly 10, as an optical element in the lighting assembly 100, is used to transmit light from a light source to a required position or direction. In this embodiment, by providing the injection-molding positioning hole 11a on the first lens part 11, the injection-molding positioning protrusions can be reduced or completely removed, thereby reducing the space occupied by the injection-molding positioning protrusions, overall reducing the space occupied by the lens assembly 10, making the structure of the entire lighting assembly 100 more compact, and making it more convenient to install the lighting assembly 100 on the motor vehicle 200.

[0032] In this embodiment, the injection-molding positioning hole 11a is used to position the first lens part 11 when injecting the first lens part 11 and the second lens part 12, avoiding rotation or movement of the first lens part 11, so as to effectively inject the second lens part 12 and the first lens part 11 together. Generally, a two-color injection-molding process can be used to first inject the first lens part 11 and then inject the second lens part 12. After the first lens part 11 is injection-molded, it is necessary to stably position the first lens part on the mold to prevent rotation or movement when injecting the second lens part 12.

[0033] Specifically, as Figure 3 shown, the first lens portion 11 is in the shape of a long strip extending along the transverse direction X, and has a first side surface 11b and a second side surface 11c which are oppositely arranged. The injection molding positioning hole 11a is a through hole penetrating the first side surface 11b and the second side surface 11c of the first lens portion 11. The first side surface 11b may face the front side of the motor vehicle 200, that is, face the forward direction Z. It should be noted that in other embodiments, the first side surface 11b may also face other directions, and the present application does not limit this. Figure 1 The transverse direction X, the vertical direction Y, and the forward direction Z which are orthogonal to each other are schematically shown in [reference], and these directions are only for simplifying the description of this embodiment and do not constitute any limitation to the protection scope of the present application. That is, in other embodiments, the installation direction and the setting angle of the lighting assembly 100 may be other forms.

[0034] In other embodiments, the injection molding positioning hole 11a may not be a through hole, but a blind hole. For example, the injection molding positioning hole 11a is a blind hole extending from the first side surface 11b of the first lens portion 11 to the second side surface 11c, as long as it can position the first lens 11 during injection molding.

[0035] The Figure 3 shown, the first lens portion 11 includes a light-emitting portion 111 and a connecting portion 112. The light-emitting portion 111 is used for transmitting light, and the connecting portion 112 is used for connecting the second lens portion 12. The connecting portion 112 may be arranged at two ends of the first lens portion 11, that is, the light-emitting portion 111 is located in the middle portion, and the two connecting portions 112 are respectively arranged at both ends of the light-emitting portion 111, so that the two connecting portions 112 are respectively located at both ends of the first lens portion 11 as a whole, for example, at the upper and lower ends along the vertical direction Y. The injection molding positioning hole 11a is arranged in the connecting portion 112 of the first lens portion, so as to avoid the influence of the injection molding positioning hole 11a on the light-emitting portion 111, so that the first lens portion 11 can normally realize the light-emitting function by using the light-emitting portion 111, and can also realize the connection with the second lens portion 12 by using the connecting portion 112. The number of the injection molding positioning holes 11a may be multiple, and the multiple injection molding positioning holes are arranged at intervals along the transverse direction Y at the end of the first lens portion 11.

[0036] For the first lens portion 11, the light-emitting portion 111 may be provided with a first thickness d1, and the connecting portion 112 may be provided with a second thickness d2, and the first thickness d1 is greater than the second thickness d2. The first thickness d1 may be the thickness between the front and rear side surfaces of the light-emitting portion 111 along the forward direction Z, and the second thickness d2 may be the thickness between the front and rear side surfaces of the connecting portion 112 along the forward direction Z. Since the light-emitting portion 111 needs to meet specific optical requirements, the flexibility of freely designing its thickness d1 is relatively small; while the connecting portion 112 is only used for connection and not for light emission, so its thickness d2 can be designed to be smaller. Thus, the connecting portion 112 for the connection function has a smaller thickness, so as to realize a more compact lens assembly 100.

[0037] In this embodiment, the first lens portion 11 is transparent, commonly known as a "white sheet", and the second lens portion 12 is black and opaque, commonly known as a "black sheet". The first lens portion 11 may be made of transparent PC material, and the second lens portion 12 may be made of black PC material.

[0038] Since the second lens portion 12 is black, its main functions are to block light and cover ugliness, so as to avoid seeing its internal structure when observing the lighting assembly from the outside. On the other hand, the second lens portion 12 is also used to connect other components, such as connecting the housing 50 in the lighting assembly 100, so as to realize the installation and positioning of the lens assembly 10.

[0039] The lighting assembly 100 is used for lighting and / or signal indicating lights of a motor vehicle 200. For example, the lighting assembly 100 is used for the position light PL of the motor vehicle 200, and can also be used for welcome lights, light show display lights, etc. The present application does not specifically limit the specific use of the lighting assembly 100.

[0040] When the lighting assembly 100 is installed on a body part 210 of the motor vehicle 200, the minimum distance d3 between the first side surface 11b of the first lens portion 11 and the body part 210 of the motor vehicle 200 is less than 4 mm. Even more preferably, the minimum distance d3 between the first side surface 11b of the first lens portion 11 and the body part 210 of the motor vehicle 200 is less than 1.5 mm. In this narrow space, that is Figure 4 in the shown D area, it is not allowed at all to provide an injection molding positioning protrusion protruding outward from the first side surface 11b on the first side surface 11b of the first lens portion 11, otherwise the injection molding positioning protrusion is very likely to interfere with the body part 210. The body part 210 is, for example, a front bumper or other parts of the motor vehicle 200, and the present application does not limit this. The embodiment of the present application replaces the traditional injection molding positioning protrusion with an injection molding positioning hole, and on the premise of realizing the positioning function, the volume of the lighting assembly 100 can be effectively reduced, and the installation space of the lighting assembly 100 on the motor vehicle 200 can be saved.

[0041] In addition, in this embodiment, the lighting assembly 100 further includes a light source 30 and a light guide 40. The light source 30 can be an LED. The light emitted by the light source 30 is transmitted through the light guide 40 to the lens assembly 10 and emitted from the first side surface 111b of the first lens portion 111 to achieve the lighting and / or signal indication function. The lighting assembly 100 may further include a housing 50 and a light shielding member 60. The light shielding member 60 is used for blocking light, and the housing 50 is used for installing and fixing the components inside the lighting assembly 100.

[0042] Although the present application has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to exemplarily illustrate the preferred embodiments of the present application and should not be construed as a limitation to the present application. The dimensional ratios in the drawings are merely illustrative and should not be construed as a limitation to the present application.

[0043] Although some embodiments of the general concept of the present application have been shown and described, those of ordinary skill in the art will understand that the present application may further include more other equivalent embodiments without departing from the general inventive concept of the present application. The protection scope of the present application is defined by the claims.
