Description

Technical Field

[0001] The present application relates to the technical field of vehicle light dimming components, and in particular to a vehicle light dimming component. Background Art

[0002] Dimming headlights typically refer to headlights that can adjust the intensity and angle of the beam. These headlights can automatically or manually adjust the beam based on driving conditions to improve nighttime driving safety and comfort. Modern cars typically use an electric motor and linkage to automatically adjust the headlight angle based on the vehicle's load, speed, and steering angle.

[0003] The working principle of existing motor-driven connecting rods to adjust car headlights is generally to convert the high-speed rotational motion of the motor into low-speed linear motion through a gear transmission system and a threaded transmission system. At the same time, a screw connection is generally used to connect with the square clip on the headlight, thereby applying thrust or pull to the headlight to change the inclination angle of the low beam lighting light.

[0004] However, the above-mentioned headlight dimming device generally requires the selection of screws of different lengths according to actual working conditions. When a longer screw is used according to design requirements, a cantilever structure will be generated. Because the vehicle vibrates continuously while driving, when a longer screw is used, the end of the screw away from the motor vibrates, which in turn disturbs the motor connected to it, causing damage to the motor. Utility Model Content

[0005] The present application provides a vehicle light dimming assembly that can solve the existing problem that when facing a long screw, the support force on the screw is not uniform, which easily causes vibration, thereby disturbing the motor and causing damage to the motor.

[0006] The technical solution of this application is as follows: A vehicle light dimming assembly, comprising:

[0007] A driving member, wherein the driving member is provided with a screw assembly that can be connected to the headlight and drive the headlight to operate, and the driving member can drive the screw assembly to move along its own length direction, and the screw assembly includes a first screw and a second screw;

[0008] A fixing frame, wherein a strip-shaped through hole extending along the width direction of the fixing frame is provided inside the fixing frame, a strip-shaped barrel extending along the length direction of the strip-shaped through hole is slidably connected inside the strip-shaped through hole, and one end of the first screw and the second screw are respectively assembled on the inner walls of both ends of the strip-shaped barrel;

[0009] A support frame, one end of which is fixedly assembled on the fixing frame, and the other end of which extends to the bottom of the second screw rod and is provided with a rotating member for supporting the second screw rod.

[0010] In one embodiment of the present application, the other end of the first screw is connected to the driving shaft of the driving member through a transmission member, and the other end of the second screw is connected to the vehicle light.

[0011] By adopting the above scheme, the screw assembly is divided into a first screw and a second screw arranged at both ends of the strip barrel, so that when the driving member is working, even if the second screw itself vibrates, the force generated by the vibration will be transmitted to the inside of the strip barrel, and then act on the bracket, without causing disturbance to the first screw, thereby avoiding disturbance to the driving member. At the same time, the support frame is set, which can effectively improve the setting stability of the second screw and reduce its vibration effect.

[0012] In one embodiment of the present application, the rotating member includes:

[0013] a bracket, the bracket being fixedly assembled on the other end of the support frame;

[0014] A supporting wheel is rotatably assembled in the bracket and is used to support the second screw rod.

[0015] By adopting the above solution and setting up a second screw, the supporting wheel can rotate and support the second screw as the second screw moves. The device can not only improve the support stability of the second screw, but also reduce the resistance encountered when the second screw and the rotating part move relative to each other.

[0016] In one embodiment of the present application, the driving member includes:

[0017] a motor housing, wherein the transmission member is disposed in the motor housing;

[0018] A drive motor is disposed inside the motor housing, and a drive shaft of the drive motor is connected to the transmission member.

[0019] In one embodiment of the present application, the driving motor is a servo motor or a stepper motor.

[0020] In one embodiment of the present application, the transmission member includes:

[0021] A threaded sleeve, wherein one end of the first screw is disposed inside the threaded sleeve and is threadedly connected to the threaded sleeve, and one end of the threaded sleeve is fixedly connected to the drive shaft of the drive motor;

[0022] A limiting ring is provided on the motor housing and is coaxially sleeved on the outside of the first screw. The limiting ring is slidably connected to the first screw.

[0023] By adopting the above solution, by setting a threaded sleeve, a first screw and a limit ring, the threaded sleeve connected to the drive motor can convert the rotational motion into the linear displacement of the first screw, so that the subsequent first screw can drive the second screw to move linearly, thereby adjusting the car lights.

[0024] In one embodiment of the present application, two mounting holes are provided on the fixing frame, and the two mounting holes are respectively arranged on both sides of the strip-shaped through hole.

[0025] In one embodiment of the present application, the supporting wheel includes:

[0026] A roller portion, the roller portion being rotatably mounted on the bracket, and the roller portion being provided with an annular rubber ring along its circumference;

[0027] The limiting parts are coaxially arranged at both ends of the roller part. The diameter of the limiting parts is larger than the diameter of the roller part. The two limiting parts and the roller part enclose a support channel for supporting the second screw.

[0028] By adopting the above solution, when the roller portion rotates, it is ensured that a stable support effect can be provided between the roller portion and the second screw rod, while the second screw rod can perform linear displacement on the roller portion.

[0029] In one embodiment of the present application, one end of the first screw and the second screw are each provided with a wavy first rough surface along their circumference.

[0030] In one embodiment of the present application, a second rough surface extending along the length direction of the inner wall of the strip-shaped cylinder is provided, and the second rough surface is adapted to the two first rough surfaces.

[0031] By adopting the above scheme, a second rough surface is set on the inner wall of both ends of the strip barrel, and a first rough surface is opened on the outside of the first screw and the second screw. The wavy shapes of the first rough surface and the second rough surface are engaged with each other, thereby improving the tightness of the first screw and the second screw when they are fixed inside the strip barrel, and improving the stability of the axial fixation of the first screw and the second screw.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. By providing a strip-shaped barrel and fixing the first and second screws to the two ends of the strip-shaped barrel respectively, when the first screw extends to the headlight and vibrates, the stress generated by the vibration acts on the strip-shaped barrel and then on the bracket, ensuring that when the first screw vibrates due to the bumps of the vehicle due to its long length, the second screw will not be disturbed, thereby ensuring the stability of the motor during operation. At the same time, when the headlight is pushed or pulled, the first screw can drive the strip-shaped barrel to move linearly inside the bracket, and the strip-shaped barrel drives the second screw to move linearly, thereby not affecting the normal regulation of the headlight by the device.

[0034] 2. By setting up a support frame, by setting up a support frame on the bracket, and using the rotating wheel at one end of the support frame to lift and support the first screw to extend toward the other end of the headlight, the support stability of the first screw can be improved and the vibration of the first screw due to its long length can be reduced.

[0035] 3. By providing a second rough surface on the inner wall at both ends of the strip barrel, and opening a first rough surface on the outside of one end of the first screw and the second screw that penetrates into the interior of the strip barrel, when the first screw and the second screw are fixed inside the strip barrel, the wave shapes of the first rough surface and the second rough surface engage with each other, thereby improving the tightness of the first screw and the second screw when they are fixed inside the strip barrel, and improving the stability of the axial fixation of the first screw and the second screw.

[0041] The following is combined with Figure 1-4 The vehicle light dimming component provided in this application is further described in detail.

[0042] See also Figure 1 and Figure 2 , is a headlight dimming assembly provided in an embodiment of the present application, comprising: a driving member 1, a fixing frame 2 and a supporting frame 3. The driving member 1 is provided with a screw assembly 11 that can be connected to the headlight and drive the headlight. The driving member 1 can drive the screw assembly 11 to move along its own length direction. The screw assembly 11 includes a first screw 111 and a second screw 112. The fixing frame 2 is provided with a strip-shaped through hole 21 extending along the width direction of the fixing frame 2. A strip cylinder 22 extending along the length direction of the strip through hole 21 is slidably connected to the inside of the strip through hole 21. One end of the first screw 111 and the second screw 112 are respectively assembled on the inner walls of the two ends of the strip cylinder 22, and one end of the support frame 3 is fixedly assembled on the fixed frame 2, and the other end extends to the bottom of the second screw 112, and is provided with a rotating part 31 for supporting the second screw 112. By setting up a split screw assembly 11, the first screw 111 can drive the second screw 112 to move. When the second screw 112 deflects and vibrates, the second screw 112 cannot disturb the first screw 111, and thus will not disturb the motor.

[0043] The other end of the first screw rod 111 is connected to the driving shaft of the driving member 1 through a transmission member 14 , and the other end of the second screw rod 112 is connected to the vehicle lamp.

[0044] See also Figure 4 The rotating member 31 includes: a bracket 311 and a supporting wheel 312. The bracket 311 is fixedly assembled on the other end of the support frame 3. The supporting wheel 312 is rotatably assembled in the bracket 311 to support the second screw 112. By setting the bracket 311 and the supporting wheel 312, and setting the second screw 112 on the supporting wheel 312, the support stability of the second screw 112 is improved, and the resistance of the second screw 112 to the movement on the supporting wheel 312 is also reduced.

[0045] See also Figure 1 and Figure 3 The driving member 1 includes: a motor housing 12 and a driving motor 13, the transmission member 14 is arranged in the motor housing 12, the driving motor 13 is arranged inside the motor housing 12, and the driving shaft of the driving motor 13 is connected to the transmission member 14.

[0046] The driving motor 13 is a servo motor or a stepping motor.

[0047] The transmission member 14 includes: a threaded sleeve 141 and a limiting ring 142. One end of the first screw 111 is arranged inside the threaded sleeve 141 and is threadedly connected to the threaded sleeve 141. One end of the threaded sleeve 141 is fixedly connected to the drive shaft of the drive motor 13. The limiting ring 142 is arranged on the motor housing 12 and is coaxially sleeved on the outside of the first screw 111. The limiting ring 142 is slidingly connected to the first screw 111. The drive motor 13 is used to drive the transmission member 14 to operate, so that the rotational motion of the drive shaft of the drive motor 13 is converted into the linear displacement of the first screw 111, so as to adjust the illumination angle of the car light.

[0048] The fixing frame 2 is provided with two mounting holes 23 , and the two mounting holes 23 are respectively arranged on both sides of the strip-shaped through hole 21 .

[0049] See also Figure 4 The supporting wheel 312 includes: a roller portion 3121 and a limiting portion 3123. The roller portion 3121 is rotatably assembled on the bracket 311. The roller portion 3121 is provided with an annular rubber ring 3122 along its circumference. The limiting portion 3123 is coaxially arranged at both ends of the roller portion 3121. The diameter of the limiting portion 3123 is larger than the diameter of the roller portion 3121. The two limiting portions 3123 and the roller portion 3121 form a supporting channel for supporting the second screw 112. By providing the roller portion 3121 and the limiting portion 3123, when the second screw 112 is provided on the roller portion 3121, the second screw 112 can be limited and displaced on the roller portion 3121 while the limiting portion 3123 is used to limit the side of the second screw 112.

[0050] See also Figure 2 One end of the first screw 111 and the second screw 112 are respectively provided with a wavy first rough surface 1110 along their own circumference.

[0051] The inner wall of the strip barrel 22 is provided with a second rough surface 221 extending along its own length direction. The second rough surface 221 is wavy and adapted to the two first rough surfaces 1110. After the first screw 111 and the second screw 112 are arranged inside the strip barrel 22, the first rough surface 1110 and the second rough surface 221 are engaged with each other, so that the axial fixation between the first screw 111, the second screw 112 and the strip barrel 22 is more stable.

[0052] In summary, when the angle of the headlight needs to be adjusted, the motor rotates to drive the threaded sleeve 141 to rotate. Due to the threaded fit between the first screw 111 and the threaded sleeve 141, and the limiting effect of the limiting ring 142 on the first screw 111, the first screw 111 can be linearly displaced along its own length. The first screw 111 drives the motorized cylinder 22 to move on the bracket 311, thereby driving the second screw 112 to move in a limited position, thereby adjusting the angle of the headlight.

[0053] At the same time, the bracket 311 and the support frame 3 can provide good and stable support for the second screw rod 112 even when the second screw rod 112 is long, thereby preventing the second screw rod 112 from vibrating continuously due to its own length, thereby improving the stability of adjusting the angle of the car light.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
