[0027] Embodiments of the present application will be described in detail below with reference to the drawings. It should be understood that these embodiments of the present application are mainly possible embodiments intended to illustrate the technical solution of the present application, and should not be interpreted as limitations of the technical solution of the present application. In this Description, identical or similar components are indicated with identical or similar reference numerals.
[0028] is a schematic structural view of a motor vehicle 200 provided in an embodiment of the present application;is a partial enlarged view C of the motor vehicle 200 shown in;is a schematic view of section A-A of the motor vehicle 200 shown in;is a partial enlarged view D of the motor vehicle 200 shown in;is a schematic structural view of a lighting assembly 100 in the motor vehicle 200 shown in; andis a front view of the lighting assembly 100 shown in.
[0029] As shown in Figs. 1-6, the 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, wherein the lens assembly 10 includes a first lens portion 11 and a second lens portion 12, the first lens portion 11 and the second lens portion 12 are injection-moulded together, and an injection-moulding positioning hole 11a is provided on the first lens portion 11.
[0031] The lens assembly 10 serves as an optical element in the lighting assembly 100, which is used to transmit light from a light source to a desired position or direction. In this embodiment, by providing the injection-moulding positioning hole 11a on the first lens portion 11, injection-moulding positioning protrusions can be reduced or completely removed, thereby reducing the space occupied by the injection-moulding positioning protrusions, and reducing the space occupied by the lens assembly 10 as a whole, so that the structure of the entire lighting assembly 100 is more compact, and it is more convenient to install the lighting assembly 100 on the motor vehicle 200.
[0032] In this embodiment, the injection-moulding positioning hole 11a is used to position the first lens portion 11 when the first lens portion 11 and the second lens portion 12 are injection-moulded, so as to prevent the first lens portion 11 from rotating or moving, thereby effectively injection-moulding the second lens portion 12 and the first lens portion 11 together. Generally speaking, a two-colour injection moulding process may be used to first injection-mould the first lens portion 11, and then injection-mould the second lens portion 12. After the first lens portion 11 is injection-moulded, it is necessary to stably position the first lens portion on a mould to prevent rotation or movement when the second lens portion 12 is injection-moulded.
[0033] Specifically, as shown in, the first lens portion 11 is in the shape of a long strip extending along a transverse direction X, and has a first side surface 11b and a second side surface 11c which are arranged opposite to each other, and the injection-moulding positioning hole 11a is a through hole that penetrates 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, toward a forward direction Z. It is worth noting that, in other embodiments, the first side surface 11b may also face other directions, and the present application does not impose any limitation on this. The transverse direction X, a vertical direction Y, and the forward direction Z that are orthogonal to each other are schematically shown in. These directions are only for simplifying the description of this embodiment, and do not impose any limitation on the scope of protection of the present application. That is, in other embodiments, the installation direction and setting angle of the lighting assembly 100 may be in other forms.
[0034] In other embodiments, the injection-moulding positioning hole 11a may not be a through hole but a blind hole. For example, the injection-moulding positioning hole 11a is a blind hole that extends from the first side surface 11b to the second side surface 11c of the first lens portion 11, as long as the first lens 11 can be positioned during injection moulding.
[0035] Furthermore, as shown in, the first lens portion 11 includes a light emitting portion 111 and a connecting portion 112, wherein the light emitting portion 111 is used to transmit light, and the connecting portion 112 is used to connect the second lens portion 12. The connecting portion 112 may be arranged to be located at two end portions of the first lens portion 11, that is, the light emitting portion 111 is located in the middle, and two connecting portions 112 are arranged at two ends of the light emitting portion 111, respectively, so that the two connecting portions 112 are located at the two ends, for example, upper and lower ends along the vertical direction Y, of the first lens portion 11 as a whole, respectively. The injection-moulding positioning hole 11a is arranged at the connecting portion 112 of the first lens portion, so as to prevent the injection-moulding positioning hole 11a from affecting the light emitting portion 111, so that the first lens portion 11 can use the light emitting portion 111 to realize a normal light emitting function, and can also use the connecting portion 112 to realize the connection with the second lens portion 12. The number of the injection-moulding positioning holes 11a may be multiple, and the multiple injection-moulding positioning holes are arranged at intervals along the transverse direction X at an end portion 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, wherein the first thickness d1 is greater than the second thickness d2. The first thickness d1 may be the thickness between 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 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 the thickness d1 thereof is relatively small. However, the connecting portion 112 is only used for connection and is not used for light emission. Therefore, the connecting portion may be designed to have a smaller thickness d2. Thus, the connecting portion 112 used for connection function has a smaller thickness, so as to realize a lens assembly 100 with a more compact structure.
[0037] In this embodiment, the first lens portion 11 is transparent, commonly known as a "white lens piece", and the second lens portion 12 is black and opaque, commonly known as a "black lens piece". 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] The second lens portion 12 is black, and its main function is to block light and hide ugliness, so as to prevent the internal structure of the lighting assembly from being seen when viewing the lighting assembly from the outside. Additionally, the second lens portion 12 is further used to connect other components, for example, connecting a housing 50 in the lighting assembly 100, so as to achieve the installation and positioning of the lens assembly 10.
[0039] The lighting assembly 100 is used for lighting and / or signal indication lamps of the motor vehicle 200. For example, the lighting assembly 100 is used for a position light PL of the motor vehicle 200, and may also be used for a welcome light, a light show display light, 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 component 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 component 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 component 210 of the motor vehicle 200 is less than 1.5 mm. In this narrow space, i.e., area D shown in, it is not allowed at all for the first lens portion 11 to be provided with, on its first side surface 11b, an injection-moulding positioning protrusion that protrudes outwards from the first side surface 11b, otherwise the injection-moulding positioning protrusion is likely to interfere with the body component 210. The body component 210 is, for example, a front bumper or other components of the motor vehicle 200, and the present application does not impose any limitation on this. In the embodiment of the present application, the traditional injection-moulding positioning protrusion is replaced with the injection-moulding positioning hole, which can effectively reduce the volume of the lighting assembly 100 and save the installation space of the lighting assembly 100 on the motor vehicle 200 on the premise of achieving the positioning function.
[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 may be an LED. Light emitted by the light source 30 is transmitted to the lens assembly 10 through the light guide 40 and emitted from the first side surface 111b of the first lens portion 111 to achieve lighting and / or signal indication functions. The lighting assembly 100 may further include a housing 50 and a light shielding member 60. The light shielding member 60 is used to block light, and the housing 50 is used to install and fix the internal components of the lighting assembly 100.
[0042] Although the present application has been described with reference to the drawings, the embodiments disclosed in the drawings are intended to provide an exemplary description of preferred implementations of the present application, and must not be construed as limiting the present application. The dimensional proportions in the drawings are merely schematic, and must not be construed as limiting the present application.
[0043] Although some embodiments of the general concept of the present application have been shown and described, those skilled in the art will understand that the present application may include other equivalent embodiments without departing from the general inventive concept of the present application, and the scope of protection of the present application is defined by the claims.
