Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a light adjustment component and a light carpet projection device. Background Technology

[0002] The automotive headlight system mainly consists of low beam and high beam headlights. Their beams are fixed, and the light diffuses towards the distance or forward, providing the driver with a clear view of the road and conveying vehicle status information to other road users.

[0003] According to the road cycling grid spotlight device based on laser grating disclosed in announcement number CN208670888U, it projects a grid-shaped laser line. Because the grid line has a regular shape, it will significantly twist and deform when encountering uneven road surfaces. Riders can observe this phenomenon and make timely adjustments to ensure riding safety. However, this solution only ensures the driver's safety and cannot convey the vehicle's specific width or the area it is about to enter through the light.

[0004] Therefore, a light adjustment component and a light carpet projection device are proposed to solve the technical problem that existing solutions cannot display the specific width of the vehicle and the area the vehicle is about to enter. Utility Model Content

[0005] In view of this, the present invention proposes a light adjustment component and a light carpet projection device, which solves the technical problem that the existing solution cannot display the specific width of the vehicle and the area that the vehicle is about to enter. It can play a technical role in reminding other traffic participants to know the status information of the vehicle in a timely manner.

[0006] This utility model proposes a light adjustment component, comprising:

[0007] A light source, installed on the car, is used to emit light in the direction the car is traveling;

[0009] A lens mechanism, mounted on the base and located on the optical axis of the light source, is used to converge and adjust the output direction of the light path;

[0010] A light guiding mechanism is rotatably mounted on the lens mechanism, and the rotation angle is lockable. It is located on the optical axis of the lens mechanism and is used to further adjust the direction of the light path projected onto the ground to form a light carpet area, wherein the position of the light carpet area relative to the light source is adjustable.

[0011] Based on the above technical solutions, preferably, the lens mechanism includes:

[0012] The lens barrel has one end snapped onto the base and the other end rotatably connected to the light guiding mechanism, and the inside of the lens barrel is hollow.

[0013] The first lens is snapped into the base and located on the optical axis of the light source, and is used to initially converge and adjust the output direction of the light path.

[0014] The second lens is embedded in the lens barrel, located on the optical axis of the light source, and close to the light guiding mechanism, for secondary adjustment of the optical path.

[0015] Based on the above technical solutions, preferably, the first lens is disposed at the center of the base and forms an angle with the central axis of the light source, for inputting the light path along the axial direction of the lens barrel to the second lens.

[0016] Based on the above technical solution, preferably, the base extends outward along its own axis on the side near the first lens to form at least two first snap-fit ​​parts and at least two first receiving parts. The at least two first snap-fit ​​parts and the at least two first receiving parts are circumferentially distributed on the base, and the first snap-fit ​​parts and the first receiving parts are staggered. The at least two first receiving parts abut against one end face of the first lens, and the at least two first snap-fit ​​parts snap against the other end face of the first lens.

[0017] Based on the above technical solution, preferably, the base extends outward along its own axis on the side near the first lens to form at least two second snap-fit ​​parts and at least two second receiving parts. Each second snap-fit ​​part is provided with a snap-fit ​​hole, and each second receiving part is provided with a receiving groove. The lens barrel protrudes outward on the side near the base to form a snap-fit ​​member and a receiving member adapted to the snap-fit ​​hole, so that when the snap-fit ​​member is located in the snap-fit ​​hole, the receiving member is located in the receiving groove.

[0018] Based on the above technical solution, preferably, the at least two second latching portions are located on the side of the at least two first receiving portions away from the first lens, and the at least two second receiving portions are located on the side of the at least two first latching portions away from the first lens.

[0019] Based on the above technical solutions, preferably, the lens barrel is provided with an embedding groove adapted to the second lens on the side near the light guiding mechanism, for limiting the second lens.

[0020] Based on the above technical solutions, preferably, the light guiding mechanism includes:

[0021] The cover has a mating groove on the side near the lens mechanism and is nested in the end of the lens barrel away from the base;

[0022] A grating section, located at the center of the cover, is used to adjust the direction of the light path projected onto the ground to form a light carpet area;

[0023] A locking unit is provided on the cover body for locking the angle of the cover body relative to the lens barrel.

[0024] Based on the above technical solutions, preferably, the locking unit includes a connecting part and a fastener. The connecting part is disposed on the circumferential side of the cover and has an arc-shaped hole. One end of the fastener passes through the arc-shaped hole and is connected to the lens mechanism to lock the angle of the cover relative to the lens mechanism.

[0025] On the other hand, this utility model also provides a light carpet projection device, comprising:

[0026] At least two light sources are correspondingly installed on the car to emit light in the direction of the car's movement;

[0027] At least two light adjustment components as described above are respectively mounted on the light source, for projecting a light carpet onto the ground in front of the car along the direction of travel of the car and displaying the width of the car through the light carpet.

The car is equipped with a light source, a lens mechanism, and a light guiding mechanism that can adjust the light path during the light propagation process multiple times, so that the light emitted by the light source is projected onto the ground, and the adjusted light source can display a light carpet of specific width on the ground; in this way, on the one hand, surrounding traffic participants can see the area that the car is about to enter; on the other hand, when the vehicle is moving into a narrow space, it can be quickly determined whether the car can pass through the narrow space smoothly.

[0030] 2. The light source is configured as a high-power amber LED point light source. Compared with white, yellow or red, this amber color can play an effective role in reminding and warning.

[0031] 3.

[0044] The technical solution will now be explained. The existing solution can only ensure driver safety and cannot use light to convey the vehicle's width or the area it is about to enter. Therefore, if... Figure 1 and 2 As shown, this utility model provides a light adjustment component, including:

[0045] Light source 100 is installed on the car to emit light in the direction of the car's movement;

[0046] Base 1, which is hollow inside, is fitted onto light source 100 for transmitting light;

[0047] Lens mechanism 2 is mounted on base 1 and located on the optical axis of light source 100, used to converge and adjust the output direction of the light path;

[0048] The light guiding mechanism 3 is rotatably mounted on the lens mechanism 2, and the rotation angle can be locked. It is located on the optical axis of the lens mechanism 2 and is used to further adjust the direction of the light path projected onto the ground to form a light carpet area, wherein the position of the light carpet area relative to the light source 100 is adjustable.

[0049] A light source 100 is installed on the car. The lens mechanism 2 and the light guiding mechanism 3 can adjust the light path during the light propagation process multiple times, so that the light emitted by the light source 100 is projected onto the ground. The adjusted light source can display a light carpet of the car's specific width on the ground. In this way, on the one hand, surrounding road users can see the area the car is about to enter, especially when the vehicle is about to overtake other vehicles from the side. Other vehicles can clearly see the area the car is about to enter, which can provide a good reminder and warning to surrounding road users. On the other hand, when the vehicle is moving into a narrow space and the driver has difficulty judging, the specific width displayed by the light carpet can quickly determine whether the car can pass through the narrow space smoothly, which is beneficial for the driver to make a quick judgment.

[0050] More specifically, the light source 100 is configured as a high-power amber LED point light source, which can play an effective reminder and warning role compared to white or red.

[0051] like Figure 2 and Figure 3 As shown, in order to ensure that the light from the light source 100 is smoothly transmitted to the light guiding mechanism 3, the lens mechanism 2 includes:

[0052] The lens tube 21 is attached to the base 1 at one end and rotatably connected to the light guiding mechanism 3 at the other end. The lens tube 21 has a hollow interior.

[0053] The first lens 22 is snapped into the base 1 and located on the optical axis of the light source 100. It is used to initially converge and adjust the output direction of the optical path.

[0054] The second lens 23 is embedded in the lens barrel 21, located on the optical axis of the light source 100, and close to the light guiding mechanism 3, for secondary adjustment of the optical path.

[0055] Specifically, the first lens 22 is used to parallel and converge the light from the light source 100, and the second lens 23 is used to collimate the light path to ensure that the light is smoothly transmitted to the light guiding mechanism 3.

[0056] like Figure 2 and Figure 3 As shown, specifically, in order to ensure that the first lens 22 transmits the light from the light source 100 to the second lens 23, the first lens 22 is set at the center of the base 1 and forms an angle with the central axis of the light source 100, so as to input the light path along the axial direction of the lens barrel 21 to the second lens 23.

[0057] There are no perfectly parallel planes on a car. The first lens 22 forms an angle with the base 1. The size of the angle is adapted to the angle between the optical axis of the light source 100 and the fixed plane. The angle formed by the first lens 22 and the base 1 is used to compensate for the angle between the light source 100 and the car surface. This ensures that the first lens 22 directs the light path along the axis of the lens barrel 21 into the second lens 23, achieving complete incident illumination.

[0058] like Figure 2 As shown, in order to fix the first lens 22 on the base 1, the side of the base 1 near the first lens 22 extends outward along its own axis to form at least two first snap-fit ​​portions 11 and at least two first receiving portions 12. The at least two first snap-fit ​​portions 11 and at least two first receiving portions 12 are circumferentially distributed on the base 1, and the first snap-fit ​​portions 11 and the first receiving portions 12 are staggered. At least two first receiving portions 12 abut against one end face of the first lens 22, and at least two first snap-fit ​​portions 11 snap into the other end face of the first lens 22.

[0059] Specifically, two elastic locking parts 11 are provided on the base 1. The two locking parts 11 are arranged opposite to each other and cooperate to form a locking space that adapts to the shape of the first lens 22. When the first lens 22 is located inside the locking space, the two locking parts 11 block one end face of the first lens 22 through the abutment part, and make the other end face of the locking parts 11 abut against the first receiving part 12, thereby restricting the first lens 22.

[0060] Furthermore, in order to prevent the first lens 22 from rotating relative to the base 1, the first lens 22 has at least one anti-rotation part. Correspondingly, an anti-rotation groove 1201 is also provided on the first receiving part 12 to correspond to the anti-rotation part. When the first lens 22 is inside the snap-fit ​​space, the anti-rotation part is located inside the anti-rotation groove 1201, thereby completely restricting the first lens 22 within the base 1.

[0061] like Figure 3 and Figure 4As shown, in order to quickly fix the lens barrel 21 onto the base 1, the lens barrel 21 is snapped onto the base 1. The side of the base 1 near the first lens 22 extends outward along its own axis to form at least two second snap-fit ​​portions 13 and at least two second receiving portions 14. Each second snap-fit ​​portion 13 is provided with a snap-fit ​​hole 1301, and each second receiving portion 14 is provided with a receiving groove 1401. The side of the lens barrel 21 near the base 1 protrudes outward to form a snap-fit ​​member 211 and a receiving member 212 that are adapted to the snap-fit ​​hole 1301, so that when the snap-fit ​​member 211 is located in the snap-fit ​​hole 1301, the receiving member 212 is located in the receiving groove 1401.

[0062] Specifically, when the lens barrel 21 is installed on the base 1 through its own snap-fit ​​part 211 and support part 212, the outer wall of the lens barrel 21 snaps into the base 1, thus completing the fixation of the base. The lens barrel 21 restricts the angle between itself and the base 1 through the support part 212, thereby completing the fixation of the lens barrel 21 and the base 1.

[0063] like Figure 2 As shown, in order to ensure that the first lens 22 and the lens barrel 21 can be fixed on the base 1 at the same time, at least two second latching parts 13 are located on the side away from the first lens 22 of at least two first receiving parts 12, and at least two second receiving parts 14 are located on the side away from the first lens 22 of at least two first latching parts 11.

[0064] In order to reduce the size of the light adjustment assembly, the first latching part 11 and the second latching part 13 are offset on the base 1, which can also ensure that the first lens 22 and the lens barrel 21 are stably fixed. This can effectively reduce the space occupied by the light adjustment assembly in the car and reduce wind resistance.

[0065] like Figure 3 and Figure 4 As shown, in order to facilitate the fixing of the second lens 23, the lens barrel 21 is provided with an embedding groove 2101 adapted to the second lens 23 on the side near the light guiding mechanism 3, which is used to limit the second lens 23.

[0066] Specifically, the diameter of the mounting groove 2101 gradually increases along the direction of light propagation, and the second lens 23 can be directly installed in the mounting groove 2101. The other end of the second lens 23 is blocked by the light guiding mechanism 3, thereby completing the fixation of the second lens 23.

[0067] like Figure 1 As shown, in order to adjust the position of the formed light carpet on the ground, the light guiding mechanism 3 includes:

[0068] The cover 31 has a mating groove 301 on the side near the lens mechanism 2, which is nested in the end of the lens barrel 21 away from the base 1;

[0069] A grating section 32 is located at the center of the cover 31 and is used to adjust the direction of the light path projected onto the ground to form a light carpet area;

[0070] The locking unit 33 is disposed on the cover 31 and is used to lock the angle of the cover 31 relative to the lens barrel 21.

[0071] When it is necessary to change the position of the light carpet on the ground, the angle between the grating part 32 and the lens barrel 21 can be changed by rotating the cover 31, thereby changing the position and size of the light carpet on the ground.

[0072] To ensure the stability of the size of the light blanket after adjustment, the locking unit 33 includes a connecting part 331 and a fastener 332. The connecting part 331 is disposed on the circumferential side of the cover 31 and is provided with an arc-shaped hole 3301. The lens barrel 21 is provided with a connecting hole 2102 corresponding to the fastener 332. One end of the fastener 332 passes through the arc-shaped hole 3301 and the connecting hole 2102 in sequence and is connected to the lens mechanism 2 to lock the angle of the cover 31 relative to the lens mechanism 2.

[0073] After the cover 31 rotates relative to the cover 31 through the mating groove 301, the connecting part 331 on the cover 31 also rotates synchronously. The fastener 332 passes through the arc-shaped hole 3301 of the fastener 332 and extends into the lens barrel 21, thereby limiting the angle between the cover 31 and the lens barrel 21, thus completing the angle locking.

[0074] Specifically, fastener 332 is configured as a bolt, which passes through the arc-shaped hole 3301 and is threadedly connected to the lens barrel 21. Correspondingly, the bolt can also be configured as a pin or other locating pin type fastener. The bolt here should not be construed as a limitation on the embodiment of this utility model.

[0075] On the other hand, this application also provides a light carpet projection device, comprising:

[0076] At least two light sources 100 are respectively set in the rearview mirror or windshield of the car to emit light in the direction of the car's travel;

[0077] At least two of the aforementioned light adjustment components are respectively mounted on the light source 100, for projecting a light carpet onto the ground in front of the car along the direction of travel of the car and displaying the width of the car through the light carpet.

[0078] This light carpet projection device can display an amber-colored light carpet on the ground, and the width of the light carpet is equal to the width of the car. Surrounding road users can see the area the car is about to enter, especially when the vehicle is about to overtake another vehicle from the side. Other vehicles can clearly see the area the car is about to enter, providing a good reminder and warning to surrounding road users. On the other hand, when the vehicle is moving into a narrow space where the driver has difficulty judging the distance, the specific width displayed by the light carpet can quickly determine whether the car can pass through the narrow space smoothly, facilitating a quick assessment by the driver.

[0079] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
