Description

[0001] This application relates to the field of vehicle lighting technology, and more particularly to an optical module, a vehicle lamp, and a vehicle. Background Technology

[0002] With the continuous development of modern automobiles, the requirements for the static appearance of vehicles are becoming increasingly stringent. Conventional headlights add a corn kernel-like viewing pattern to the outer lens to refract light and meet regulatory requirements. However, creating a viewing pattern on the inner side of the lens greatly affects the static appearance and lighting effect of the headlight. Furthermore, the shape of the viewing pattern itself is prone to producing silver streaks, affecting the static appearance of the headlight and thus reducing its quality.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] The optical module, headlights, and vehicle described in this application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] In the existing technology, the creation of viewing angle patterns on the inner side of the lens greatly affects the static appearance and lighting effect of the lamp. Secondly, due to the shape of the viewing angle patterns themselves, silver wire appearance problems are easily generated, affecting the static appearance of the lamp and thus reducing the quality of the lamp.

[0034] To address the aforementioned technical problems, this application provides an optical module including a light source, a reflector bowl, and a reflector. The light source emits light; the reflector bowl is disposed in the main light-emitting direction of the light source and is configured to adjust the light emitted by the light source and emit the light beam toward a side away from the light source; the reflector bowl is disposed on the light-emitting side of the reflector bowl and has a reflective surface; a reference plane perpendicular to the main light-emitting direction of the reflector bowl is used as a reference plane, and the reference plane is disposed on the side of the reflector bowl away from the light source; the angle between the reflective surface and the reference plane is an obtuse angle; the reflective surface is configured to reflect the light incident on it, and the light reflected by the reflective surface is angled to the main light-emitting direction of the reflector bowl. This will be described in detail below.

[0035] See Figure 1 and Figure 4 In one embodiment, the optical module includes a light source 10, a reflector bowl 20, and a reflector 30. The light source 10 is used to emit light. The reflector bowl 20 is disposed in the main light-emitting direction of the light source 10 and is configured to adjust the light emitted by the light source 10 and emit the light beam toward the side away from the light source 10. The reflector 30 is disposed on the light-emitting side of the reflector bowl 20 and has a reflective surface 311. A reference plane perpendicular to the main light-emitting direction of the reflector bowl 20 is used as a reference plane, and the reference plane is disposed on the side of the reflector 30 away from the light source 10. The angle between the reflective surface 311 and the reference plane is an obtuse angle. The reflective surface 311 is configured to reflect the light incident on the reflective surface 311, and the light reflected by the reflective surface 311 is angularly set with the main light-emitting direction of the reflector bowl 20.

[0036] By setting the reflective surface 311 at an obtuse angle to the reference surface, the reflective surface 311 faces the light source 10, allowing it to receive more light and ensuring the brightness of the light reflected by the reflective surface 311, which is beneficial to the uniformity of overall lighting. In this embodiment, the light source 10 is set at the bottom of the reflective bowl 20. When the reflective surface 311 is not facing the light source 10, the light received by the reflective surface 311 decreases, and the reflected light also decreases accordingly, resulting in a decrease in the brightness of the light reflected by the reflective surface 311. There is a brightness difference between the light reflected by the reflective bowl 20 and the light reflected by the reflective surface 311, resulting in poor uniformity when the headlight is lit.

[0037] At the same time, the light reflected by the reflecting surface 311 is angled to the main light-emitting direction of the reflecting bowl 20, and the light reflected by the reflecting surface 311 is distributed to a large viewing angle (i.e., Figure 4In the region where the value of the mid-angle α is relatively large (the same below), it meets the regulatory requirements; by setting the reflector 311 and the reference surface at an obtuse angle, the angle after reflection by the reflector 311 (the angle between the light reflected by the reflector 311 and the first axis) can be effectively improved, which can increase the illumination range of the headlight, improve driving safety, and the structure is simple. It does not require adding patterns to the lens to meet the regulatory requirements for viewing angle, which is beneficial to the aesthetics of the headlight when it is static (not lit), and effectively improves the quality of the headlight.

[0038] It should be noted that the main light emission direction of the reflector bowl 20 is as follows: Figure 4 and Figure 6 As shown in the X direction; the reflecting surface 311 is set at an obtuse angle to the reference plane, that is, the reflecting surface 311 is at the first axis (the first axis is as shown in the X direction). Figure 4 As shown by line a in the middle, which is the principal optical axis of the reflecting bowl 20, the lateral spacing gradually decreases from top to bottom. Figure 4 (Perspective).

[0039] See Figure 4 In one embodiment, the main optical axis of the reflective bowl 20 is taken as the first axis, and the angle between the reflective surface 311 and the first axis is an acute angle, that is, the lateral distance between the reflective surface 311 and the first axis gradually decreases from top to bottom.

[0040] See Figure 4 In one embodiment, the angle between the reflecting surface 311 and the reference surface is β, which satisfies: 125°≤β≤145°, such as 125°, 135°, 145°, etc.

[0041] When the value of β is less than 125°, the reflecting surface 311 tends to be vertical, and the angle between the light reflected by the reflecting surface 311 and the first axis becomes smaller (according to the principle that the angle of incidence equals the angle of reflection, when the reflecting surface 311 tends to be vertical, the angle between the light incident on the reflecting surface 311 and the reflecting surface 311 is smaller, that is, the angle between the light reflected by the reflecting surface 311 and the reflecting surface 311 is smaller, and the light reflected by the reflecting surface 311 also tends to be vertical), which is not conducive to the formation of a large viewing angle and is not easy to meet the regulatory requirements.

[0042] When the value of β is greater than 145°, the reflecting surface 311 tends to be horizontal, and the light reflected by the reflecting surface 311 tends to be vertical, which is not conducive to the formation of a large viewing angle and does not easily meet the regulatory requirements.

[0043] See Figure 1 In one embodiment, the reflector 30 is disposed on the periphery of the rim of the reflector bowl 20.

[0044] The reflector 30 is arranged around the rim of the reflector bowl 20. The reflector 30 does not block the light emitted from the reflector bowl 20, does not affect the lighting effect of the headlight, avoids dark areas when the headlight is lit, and improves the quality of the headlight.

[0045] It should be noted that the bowl-shaped opening of the reflector is the opening through which light rays are emitted. The reflector 30 is positioned around the opening and will not block the light rays emitted from the bowl-shaped opening.

[0046] See Figure 2 , Figure 3 and Figure 7 In one embodiment, the reflector 30 is disposed on the inner wall of the reflector bowl 20 via a detachable structure 40.

[0047] In this embodiment, the reflector 30 is mounted on the inner wall of the reflector bowl 20 via a detachable structure 40, meaning that the reflector 30 can be replaced and removed. Different reflectors 30 can be used to achieve different lighting effects depending on the required illumination effect of the headlight. This makes it highly adaptable and can meet the diverse needs of headlights. Furthermore, when the reflector surface 311 is damaged, only the damaged reflector 30 needs to be replaced, without having to disassemble and replace the entire reflector bowl 20, thus reducing the later usage costs.

[0048] Meanwhile, the reflector 30 is set on the inner wall of the reflector bowl 20, that is, the reflector 30 is set inside the reflector bowl 20, which does not require occupying the space outside the reflector bowl 20. This is beneficial for the arrangement of other components of the headlight and will not affect the connection and installation between the reflector bowl 20 and other components, resulting in a compact structure.

[0049] Furthermore, the reflector 30 and the reflector bowl 20 are two independent parts, which can reduce the manufacturing difficulty of the parts. When the reflector 30 and the reflector bowl 20 are integrated, the reflector 311 will obstruct the demolding due to the angle of the reflector 311 (the reflector 311 forms an angle with the inner wall of the reflector bowl 20), which increases the processing difficulty and reduces the processing accuracy. In this embodiment, the reflector and reflector 30 are detachable, so the two parts can be processed separately and then assembled after processing, which ensures the processing accuracy of each part while reducing the manufacturing difficulty.

[0050] It should be noted that different reflectors 30 are different reflective surfaces 311, such as reflective surfaces 311 with different areas, different shapes, and different angles (angles with the first axis), etc. The appropriate selection should be made according to the actual situation.

[0051] In some embodiments, the reflector 30 and the reflector bowl 20 can also be connected by a non-removable fixing method such as hot riveting, which can ensure the stability of the installation between the reflector 30 and the reflector bowl 20, and is not limited to this.

[0052] In some embodiments, the reflector 30 and the reflector bowl 20 can be integrally formed, which is beneficial to the overall consistency and improves the lighting effect of the headlights; the specific processing method can be cutting processing or other methods, which are not specifically limited here.

[0053] In one embodiment, the detachable structure 40 includes a mounting groove 41, the reflector 30 includes a connected main body 31 and a mounting part 32, the reflective surface 311 is disposed on the main body 31, the mounting groove 41 is disposed on the inner wall of the reflector bowl 20, and the mounting part 32 is inserted into the mounting groove 41 to define the relative position between the reflector 30 and the reflector bowl 20.

[0054] The reflector 30 can be installed by inserting the mounting part 32 into the mounting slot 41. The structure is simple and the operation is convenient.

[0055] In some embodiments, the detachable structure 40 further includes a connecting hole 42, a threaded hole 43, and a screw; the threaded hole 43 is disposed on the mounting portion 32; the connecting hole 42 is disposed on the bottom of the mounting groove 41; when the mounting portion 32 is inserted into the mounting groove 41, the connecting hole 42 is opposite to the threaded hole 43; the screw passes through the connecting hole 42 and is screwed into the threaded hole 43 to define the relative position between the reflector 30 and the reflector bowl 20.

[0056] When installing the reflector 30, the reflector 30 can be pre-positioned by the insertion and engagement of the mounting part 32 and the mounting groove 41, and finally tightened with screws. The structure is simple and the installation is convenient.

[0057] It should be noted that in some embodiments, the reflector block 30 and the reflector bowl 20 can be fixed by means other than screw fastening; in some embodiments, the reflector block 30 and the reflector bowl 20 can also be fixedly connected by rivets, or by applying glue to the mounting part 32 for bonding.

[0058] See Figure 5 In one embodiment, the optical module further includes a bracket 50 disposed on the light-emitting side of the reflector bowl 20; the bracket 50 is provided with a light-transmitting hole 51, which is configured to guide the light emitted from the reflector bowl 20 from the light-incident side of the bracket 50 to the light-emitting side of the bracket 50; the orthographic projection of the reflector 30 on the reference plane is located outside the orthographic projection of the light-transmitting hole 51 on the reference plane.

[0059] When the vehicle is stationary, the internal reflector 30 is not visible through the light-transmitting hole 51, meaning the reflector 30 is covered by the bracket 50, which enhances the aesthetics of the vehicle when stationary and effectively improves the quality of the headlights.

[0060] See Figure 4 and Figure 5 In one embodiment, the principal optical axis of the reflector bowl 20 is taken as the first axis, and the two reference straight lines passing through the light source 10 are taken as the second axis (e.g., Figure 4 As shown by line b in the middle (the same below) and the third axis ( Figure 4 As shown by line c in the middle (the same below), the second axis is set between the first axis and the third axis; the angle between the third axis and the first axis is 45°, and the angle between the second axis and the third axis is e, satisfying: 10°≤e≤35°, such as 10°, 20°, 30°, 35°, etc.; the reflecting surface 311 is set between the conical surface formed by the third axis rotating around the first axis and the conical surface formed by the second axis rotating around the first axis.

[0061] When the value of e is less than 10°, the distance between the second axis and the third axis is small, the reflective surface 311 within the area swept by the included angle e is small, less light is distributed within the large-angle viewing angle, the large-angle viewing angle is darker, which is not conducive to the uniformity of overall illumination; in some embodiments, the slope of the reflective surface 311 can be increased (i.e., the included angle between the reflective surface 311 and the first axis becomes smaller), so that there can be a larger reflective surface 311 even when the value of e is small, but such a setting of the reflective surface 311 tends to be vertical ( Figure 4 (View angle, the same below) The light emitted by the light source 10 cannot illuminate the reflective surface 311 well, and the angle between the light reflected by the reflective surface 311 and the first axis becomes smaller, which is not conducive to the formation of a large viewing angle; or in some embodiments, the vertical distance between the reflective surface 311 and the light source 10 can be increased, and a larger reflective surface 311 can be obtained when the value of e is small, but the size of the headlight in the main light emission direction of the reflector will be increased, occupying more space, which is not conducive to the overall shape design of the headlight.

[0062] When the value of e is greater than 35°, the reflector 311 will be close to or set on the first axis. At this time, the reflector 311 will block the light emitted from the reflector bowl 20, affecting the lighting effect of the headlight. Moreover, the reflector 311 (reflector 30) will be visible when the headlight is static, which is not conducive to improving the quality of the headlight.

[0063] In summary, when 10°≤e≤35°, the reflective surface 311 can be set at multiple angles (the angle between it and the first axis), thus forming different viewing angles (the angle between the light reflected by the reflective surface 311 and the first axis). It has strong applicability and can receive more light emitted from the light source 10 to meet the viewing angle regulations.

[0064] On the other hand, this application also relates to a vehicle light, including any of the aforementioned optical modules.

[0065] On the other hand, this application also relates to a vehicle including the aforementioned headlights.

[0066] The technical solution provided in this application aims to achieve this by setting the reflective surface 311 at an obtuse angle to the reference surface, so that the reflective surface 311 faces the light source 10, thereby receiving more light and ensuring the brightness of the light reflected by the reflective surface 311, which is beneficial to the uniformity of overall illumination. Moreover, the light reflected by the reflective surface 311 is distributed to a wide viewing angle area, which meets regulatory requirements. The structure is simple and does not require adding patterns to the lens to meet the viewing angle regulatory requirements, which is beneficial to the aesthetics of the vehicle headlight when it is static and effectively improves the quality of the vehicle headlight.
