[0037] The core of this application is to provide an anti-solar ablation device to reduce the risk of sunlight ablation on the high and low beam modules.

[0038] Another core of the present application is to provide a lamp having the above-mentioned anti-sun ablation device.

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] When sunlight shines on the lens-based high and low beam modules, the focusing effect of the lens can cause the light to concentrate in a specific area, causing the temperature in that area to rise rapidly. Some parts of the high and low beam modules are made of plastic, and when the light concentrates on these plastic parts, they are prone to ablation and damage.

[0041] For this reason, Figure 1As shown, the embodiment of the present application discloses an anti-sun ablation device, comprising a bracket 100, a shading assembly 200, and a driving assembly 300. The driving assembly 300 drives the first blade assembly 201 and the second blade assembly 202 to rotate, so that the shading assembly 200 switches between a closed state and an open state. When the shading assembly 200 is in the closed state, the shading assembly 200 can block sunlight to prevent light from entering the headlight, thereby reducing the risk of sunlight ablation on the high and low beam modules.

[0042] The following will be combined Figures 1 to 7 The anti-solar ablation device disclosed in the embodiment of the present application is specifically explained and illustrated.

[0043] Among them, Figure 2 As shown, the shading assembly 200 includes a first blade assembly 201 and a second blade assembly 202. The first blade assembly 201 and the second blade assembly 202 are respectively rotatably disposed on the bracket 100, with the first blade assembly 201 located above the second blade assembly 202. At the same time, the driving assembly 300 can drive the first blade assembly 201 and the second blade assembly 202 to rotate, so that the shading assembly 200 can be switched between a closed state and an open state. Therefore, when the shading assembly 200 is in the closed state, it can block sunlight and prevent light from entering the headlights, thereby reducing the risk of sunlight burning the high and low beam modules.

[0044] In some embodiments, as Figure 1 and Figure 2 As shown, the bracket 100 may include an upper support plate 103, a lower support plate 104 and a connecting plate 105, and the connecting plate 105 is connected to the same end side of the upper support plate 103 and the lower support plate 104. The light shielding assembly 200 is installed between the upper support plate 103 and the lower support plate 104. For ease of understanding, the two relatively arranged ends of the shading assembly 200 are defined as the first end and the second end respectively, and the first end of the shading assembly 200 is the driving end. The first end of the shading assembly 200 is rotatably set on the connecting plate 105 and is connected to the driving assembly 300, so as to drive the first blade assembly 201 and the second blade assembly 202 to rotate through the driving assembly 300, thereby realizing the switching of the shading assembly 200 between the closed state and the open state. At the same time, the second end of the shading assembly 200 is the supporting end. A supporting cover plate 101 is provided at the second end of the shading assembly 200, and the supporting cover plate 101 can be fixed to the end side of the upper support plate 103 and the lower support plate 104 opposite to the connecting plate 105 by a detachable connection method such as bolts or clamping, so that the shading assembly 200 can be rotatably installed between the upper support plate 103 and the lower support plate 104.

[0045] In some embodiments, as Figure 2 and Figure 3As shown, the driving assembly 300 may include a motor 301 and a mounting base 302, and the motor 301 may be fixed to the connecting plate 105 of the bracket 100 via the mounting base 302. Two motors 301 may be used, so that the two motors 301 can respectively drive the first blade assembly 201 and the second blade assembly 202 to rotate, so as to realize the switching of the shading assembly 200 between the closed state and the open state. Of course, as Figures 1 to 7 As shown, a single motor 301 can also be used to simultaneously drive the first blade assembly 201 and the second blade assembly 202 to rotate, thereby switching the light shielding assembly 200 between the closed state and the open state. It should be noted that when there are two motors 301, two mounting brackets 302 can also be used to fix the two motors 301 to the connecting plate 105 of the bracket 100 respectively.

[0046] In some embodiments, as Figures 1 to 7 As shown, there is one drive assembly 300, and the drive assembly 300 can adopt one motor 301. Among them, the drive assembly 300 can be connected to any one of the first blade assembly 201 and the second blade assembly 202, that is, the drive assembly 300 can be connected to the first blade assembly 201, and can also be connected to the second blade assembly 202. At the same time, the first blade assembly 201 and the second blade assembly 202 are connected by at least one connecting member 203, so that the drive assembly 300 drives one of the first blade assembly 201 and the second blade assembly 202 to rotate, and the other of the first blade assembly 201 and the second blade assembly 202 is linked, thereby achieving the purpose of driving the first blade assembly 201 and the second blade assembly 202 to rotate simultaneously by one motor 301, so as to achieve the purpose of switching the light-shielding assembly 200 between the closed state and the open state.

[0047] In some embodiments, as Figure 2 and Figure 3As shown, the drive assembly 300 can be connected to the first blade assembly 201. The first blade assembly 201 includes a first rotating shaft 2011 and a first blade 2012 arranged axially along the first rotating shaft 2011, and the second blade assembly 202 includes a second rotating shaft 2021 and a second blade 2022 arranged axially along the second rotating shaft 2021. The first rotating shaft 2011 and the second rotating shaft 2021 are arranged parallel to the upper support plate 103 and the lower support plate 104 of the bracket 100. The motor 301 of the drive assembly 300 is splined to the driving end of the first rotating shaft 2011, so that the motor 301 of the drive assembly 300 drives the first blade assembly 201 to rotate in the same direction as the motor 301. A connector 203 is connected to at least one end surface of the first rotating shaft 2011 and the second rotating shaft 2021. The connector 203 can be connected to one end surface of the first rotating shaft 2011 and the second rotating shaft 2021, or it can be connected to both end surfaces of the first rotating shaft 2011 and the second rotating shaft 2021 to ensure the stability of the transmission between the first rotating shaft 2011 and the second rotating shaft 2021. It should be noted that the motor 301 of the drive assembly 300 can also be connected to the driving end of the second rotating shaft 2021 via a spline, which is not limited herein.

[0048] In some embodiments, as Figure 3 As shown, the connecting member 203 can be a connecting rod, and the connecting member 203 can be connected to the end faces of the first rotating shaft 2011 and the second rotating shaft 2021 along the oblique tangent direction of the first rotating shaft 2011 and the second rotating shaft 2021, so that the second blade 2022 of the second blade assembly 202 moves in the opposite direction to the first blade 2012 of the first blade assembly 201, so that when the motor 301 of the driving assembly 300 drives the first blade assembly 201 to rotate, the first blade assembly 201 can drive the second blade assembly 202 to rotate in the opposite direction through the connecting member 203, so as to realize the switching between the closed state and the open state of the first blade 2012 of the first blade assembly 201 and the second blade 2022 of the second blade assembly 202.

[0049] like Figure 3 As shown, when the motor 301 of the drive assembly 300 drives the first rotating shaft 2011 to rotate clockwise, the second rotating shaft 2021 rotates counterclockwise driven by the first rotating shaft 2011. At this time, the first blade 2012 and the second blade 2022 move toward each other until the first blade 2012 and the second blade 2022 are located on the same plane, and the edges of the first blade 2012 and the second blade 2022 are fitted together to block the sunlight, thereby preventing light from entering the car lights and reducing the risk of sunlight burning the high and low beam modules.

[0050] On the contrary, when the motor 301 of the driving component 300 drives the first rotating shaft 2011 to rotate counterclockwise, the second rotating shaft 2021 rotates clockwise driven by the first rotating shaft 2011. At this time, the first blade 2012 and the second blade 2022 move away from each other until the light-emitting module 400 is completely exposed between the first blade 2012 and the second blade 2022 to open the shading component 200. The light emitted by the light-emitting module 400 can pass through the shading component 200 to achieve a lighting effect.

[0051] In some embodiments, as Figure 2 and Figure 3 As shown, a first limiting column 2013 and a second limiting column 2023 are respectively provided at the edge positions of the end faces of the first rotating shaft 2011 and the second rotating shaft 2021, and the connecting line of the first limiting column 2013 and the second limiting column 2023 are respectively tangent to the first rotating shaft 2011 and the second rotating shaft 2021. At the same time, both ends of the connecting member 203 are respectively provided with connecting holes sleeved on the first limiting column 2013 and the second limiting column 2023, and the connecting holes are clearance-matched with the first limiting column 2013 and the second limiting column 2023, so that the connecting member 203 can rotate relative to the first limiting column 2013 and the second limiting column 2023, thereby realizing that when the first rotating shaft 2011 rotates, the second rotating shaft 2021 can be driven to rotate in the opposite direction.

[0052] In some embodiments, as Figure 2 As shown, the connecting plate 105 of the bracket 100 is provided with a first mounting hole 1051 and a second mounting hole 1052 for mounting the driving ends of the first rotating shaft 2011 and the second rotating shaft 2021, respectively, so that the driving end of the first rotating shaft 2011 can pass through the first mounting hole 1051 to connect with the motor 301 of the driving assembly 300, and the driving end of the second rotating shaft 2021 can be rotatably mounted in the second mounting hole 1052. Figure 1 and Figure 2 As shown, a first supporting hole 1011 and a second supporting hole 1012 for installing the supporting ends of the first rotating shaft 2011 and the second rotating shaft 2021 are respectively provided on the supporting cover plate 101, so that the supporting end of the first rotating shaft 2011 can pass through the first supporting hole 1011 of the supporting cover plate 101 and be supported in the first card slot 1013 on the supporting cover plate 101, and at the same time, the supporting end of the second rotating shaft 2021 can pass through the second supporting hole 1012 of the supporting cover plate 101 and be supported in the second card slot 1014 on the supporting cover plate 101, thereby realizing the assembly of the first blade assembly 201 and the second blade assembly 202.

[0053] like Figures 4 to 7As shown, in some embodiments, the shading assemblies 200 may be provided in two groups, and the driving assembly 300 may be located between adjacent shading assemblies 200. Thus, the first blade assemblies 201 and the second blade assemblies 202 of the two adjacent groups of shading assemblies 200 may be driven simultaneously by one driving assembly 300 to rotate, thereby achieving simultaneous switching between the open and closed states of the two adjacent groups of shading assemblies 200. Of course, the shading assemblies 200 may also be provided in three, four, or more groups to meet the requirements of different application scenarios.

[0054] like Figure 1 As shown, to facilitate the installation of the anti-sun ablation device, in some embodiments, two ear plates 102 are respectively provided on the upper support plate 103 and the lower support plate 104 of the bracket 100, so that the anti-sun ablation device can be fixed to the target position through the ear plates 102, for example, the anti-sun ablation device can be fixed in the lamp housing through the ear plates 102. In addition, the ear plates 102 of the upper support plate 103 and the lower support plate 104 are arranged perpendicular to each other, so that the anti-sun ablation device can be limited in multiple degrees of freedom, ensuring the reliability of the installation of the anti-sun ablation device. Among them, the ear plates 102 of the upper support plate 103 can be arranged parallel to the upper support plate 103, and the ear plates 102 of the lower support plate 104 can be arranged perpendicular to the lower support plate 104, so that the ear plates 102 of the upper support plate 103 and the lower support plate 104 are perpendicular to each other, thereby achieving multi-degree-of-freedom limitation of the anti-sun ablation device. Of course, the ear plate 102 of the upper support plate 103 can also be set perpendicular to the upper support plate 103, and the ear plate 102 of the lower support plate 104 can be set parallel to the lower support plate 104, so that the ear plates 102 of the upper support plate 103 and the lower support plate 104 are perpendicular to each other, which is not limited in this article.

[0055] like Figure 1 As shown, in order to improve the strength and rigidity of the bracket 100, multiple reinforcing ribs can be set on the upper support plate 103 and the lower support plate 104 of the bracket 100 to increase the rigidity and strength of the upper support plate 103 and the lower support plate 104, thereby improving the overall bearing capacity of the bracket 100.

[0056] The present application also discloses a lamp comprising a light-emitting module 400 and an anti-sun ablation device as disclosed in the above embodiment. Therefore, the anti-sun ablation device has all the technical effects of the above-mentioned anti-sun ablation device, which will not be described in detail herein. The shading component 200 is located in front of the light-emitting end of the light-emitting module 400. When the shading component 200 is in the open state, the light emitted by the light-emitting module 400 can pass through the shading component 200 to achieve a lighting effect. When the shading component 200 is in the closed state, it can block sunlight and prevent light from entering the headlight, thereby reducing the risk of sunlight ablation of the light-emitting module 400.
