Description

Technical Field

[0001] This utility model relates to the field of automotive dimming technology, and in particular to a dimming system and headlights for vehicles. Background Technology

[0002] Automotive lighting fixtures employ dimming mechanisms to adjust the range of their illumination, ensuring the light meets standard requirements for vehicle lighting. Existing dimming systems typically use a long dimming screwdriver inserted into a hexagonal socket screw mechanism on a dimming screw. Rotating this screw, which connects to the high and low beam headlights, adjusts the position of the headlights, thus achieving dimming.

[0003] However, the internal hexagonal screw mechanism on the dimming screw is often obscured by the vehicle body structure or the lamp itself, making it difficult to see the dimming hole or screw when inserting the dimming screwdriver, or the insertion angle is very tilted, resulting in low efficiency when dimming offline. Furthermore, rotating the dimming rod before it is inserted into the mating structure can easily damage the dimming hole, causing the entire lamp to be scrapped. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem that the dimming screwdriver is difficult to insert for adjustment due to the obstruction of the internal hexagon screw mating structure in the existing dimming system, this utility model provides a dimming system for vehicles with an adapter rod, which shortens the forward distance of the dimming screwdriver, avoids the situation of improper insertion or very tilted insertion angle, and indirectly improves dimming efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dimming system for vehicles, including a bracket, a transmission rod, and an adapter rod; the bracket is equipped with a power transmission component; one end of the transmission rod is rotatably disposed in the bracket and is detachably connected to the power transmission component; one end of the adapter rod is detachably connected to the power transmission component; thereby, the adapter rod causes the rotation control point to move outward, making it easier for the operator to adjust the rotation torque and control the rotation angle of the adapter rod in a relatively open space, thereby indirectly improving dimming efficiency.

[0006] The power transmission assembly includes a first gear and a second gear, both of which are bevel gears. The outer side of the first gear is rotatably mounted to the bracket, and one end of the first gear is press-fitted to an adapter rod. The end of the transmission rod located inside the bracket is press-fitted to the second gear. The end of the first gear away from the adapter rod meshes with the second gear, and the axis of the first gear is perpendicular to the axis of the transmission rod. Thus, rotating the adapter rod from the outside causes the transmission rod to rotate via the first gear, thereby providing power for dimming.

[0007] Furthermore, the axis of gear one is perpendicular to the axis of the transmission rod, and both gear one and gear two are bevel gears; thus, gear one controls gear two to have less rotational resistance.

[0008] Furthermore, the outer side of the bracket is fixedly connected to the housing, and the inside of the bracket is provided with an installation cavity and a movable cavity. The rod body of the transmission rod is rotatably installed in the installation cavity, the second gear is located in the movable cavity, and the tooth surface of the first gear is located in the movable cavity; thus, the bracket provides support and positioning for the transmission rod and the gear.

[0009] Furthermore, a dimming gear is pressed and fixed at the end of the transmission rod away from the second gear; thus, the transmission rod controls the dimming mechanism through the dimming gear.

[0010] Furthermore, the adapter rod is a rigid rod, and the axis of the adapter rod is on the same straight line as the axis of gear one. The end of the adapter rod away from gear one is provided with an internal hexagonal slot. Therefore, the torque of the adapter rod is less than that of the existing flexible shaft. And it is compatible with the dimming screwdriver through the internal hexagonal slot.

[0011] Furthermore, the adapter rod has several raised ribs circumferentially arranged on its body, and the long side of the raised ribs is parallel to the axis of the adapter rod; thereby, the bending strength of the adapter rod is enhanced, and the service life of the adapter rod is indirectly extended.

[0012] Furthermore, the dimming system also includes a ring-shaped mounting bracket, one side of which is fixedly connected to the housing. The end of the adapter rod away from the first gear passes through the mounting bracket, and the rod body is rotatably connected to the mounting bracket. Thus, the mounting bracket provides support and positioning for the adapter rod.

[0013] Furthermore, the adapter rod has at least one elastic fin circumferentially arranged on its body. One end of the elastic fin is fixedly connected to the adapter rod, such that the elastic fin and the adapter rod form an angle, with the opening of the angle facing the mounting frame. Thus, after the adapter rod passes through the annular mounting frame, it unfolds outward. The distance between the farthest end of the unfolded elastic fin and the axis of the adapter rod is greater than the inner diameter of the mounting frame. In this way, the elastic fin abuts against the mounting frame, restricting the axial movement of the adapter rod and preventing the adapter rod from coming off during vehicle operation.

[0014] Furthermore, the adapter rod has grooves on its body, and each groove corresponds to an elastic fin. Thus, when the adapter rod passes through the annular mounting bracket, the elastic fins are compressed and retracted to the grooves, reducing the resistance of the elastic fins to the adapter rod as it passes through the mounting bracket.

[0015] A vehicle light, including the aforementioned dimming system for vehicles.

[0016] The beneficial effect of this utility model is that the vehicle dimming system of this utility model is equipped with an adapter rod, which makes the rotation control point move outward, making it easier for the operator to adjust the rotation torque and control the rotation angle of the adapter rod in a relatively open space, reducing the difficulty of dimming for the operator and indirectly improving the dimming efficiency.

[0017] The vehicle dimming system of this utility model is equipped with a mounting bracket, which, together with the bracket, supports the adapter rod, preventing the adapter rod from swaying radially when the car is in motion, thereby indirectly ensuring the service life of the adapter rod.

[0018] The vehicle dimming system of this utility model is equipped with elastic fins, which, together with the mounting bracket, serve as a limit for the adapter rod, preventing the adapter rod from moving out along its axis when the car is in motion. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] like Figures 1-4 The diagram shows the preferred embodiment of this utility model, a vehicle dimming system, including a bracket 1, a transmission rod 21, a gear 32, and an adapter rod 31; see reference. Figure 1 , Figure 2 , Figure 4The bracket 1 is fixedly connected to the outer side of the housing 5. The bracket 1 has an installation cavity 11 and a movable cavity 12 inside. One end of the transmission rod 21 is rotatably installed in the bracket 1, and the rod body is rotatably installed in the installation cavity 11. The outer side of the gear 32 is rotatably installed on one side of the bracket 1, and the tooth surface of the gear 32 is located in the movable cavity 12. The end of the transmission rod 21 located in the bracket 1 is provided with a gear 22, which is located in the movable cavity 12, and the tooth surface of the gear 22 meshes with the gear 32. The end of the gear 32 away from the tooth surface is provided with a pressing groove 321, and one end of the adapter rod 31 is in transition fit with the pressing groove 321. Thus, rotating the adapter rod 31 from the outside causes the adapter rod 31 to drive the transmission rod 21 to rotate through the gear 32, thereby providing power for dimming. The adapter rod 31 moves the rotation control point outward, making it easier for the operator to adjust the rotation torque and control the rotation angle of the adapter rod 31 in a relatively open space, thereby indirectly improving the dimming efficiency.

[0027] in: Reference Figure 2 The axis of gear 1 32 is perpendicular to the axis of transmission rod 21. Both gear 1 and gear 2 22 are bevel gears, which reduces rotational resistance. The end of transmission rod 21 away from gear 2 22 is press-fitted with a dimming gear that controls the dimming mechanism. The adapter rod 31 is a rigid rod. The axis of adapter rod 31 and the axis of gear 1 32 are on the same straight line, that is, the intersection angle is zero degrees. The end of adapter rod 31 away from gear 1 32 is provided with an internal hexagonal slot 33. The torque of the rigid adapter rod 31 is less than the torque of the existing flexible shaft, and it is adapted to the dimming screwdriver through the internal hexagonal slot 33.

[0028] Reference Figure 1 , Figure 2 The adapter rod 31 has several raised ribs circumferentially arranged on its body, and the long side of the raised ribs is parallel to the axis of the adapter rod 31; thereby, the bending strength of the adapter rod 31 is enhanced, and the service life of the adapter rod 31 is indirectly enhanced.

[0029] In addition, refer to Figure 3 , Figure 4 The dimming system also includes a ring-shaped mounting bracket 4. One side of the mounting bracket 4 is fixedly connected to the housing 5. The end of the adapter rod 31 away from the gear 32 passes through the mounting bracket 4, and the rod body of the adapter rod 31 is rotatably connected to the mounting bracket 4. Thus, the mounting bracket 4 serves to support and position the adapter rod 31.

[0030] Reference Figure 2 , Figure 4The adapter rod 31 has at least one elastic fin 311 circumferentially arranged on its body. In this embodiment, there are two elastic fins 311 arranged symmetrically. One end of the elastic fin 311 is fixedly connected to the adapter rod 31, so that the elastic fin 311 and the adapter rod 31 form an angle, with the opening of the angle facing the mounting frame 4. Thus, after the adapter rod 31 passes through the annular mounting frame 4, it unfolds outward, and the distance between the farthest end of the unfolded elastic fin 311 and the axis of the adapter rod 31 is large. The inner diameter of the mounting bracket 4 is such that the elastic fins 311 abut against the mounting bracket 4, restricting the axial movement of the adapter rod 31 and preventing the adapter rod 31 from coming off during vehicle operation; the body of the adapter rod 31 has a groove 312, which corresponds one-to-one with the elastic fins 311; when the adapter rod 31 passes through the annular mounting bracket 4, the elastic fins 311 are squeezed and retracted to the groove 312, reducing the resistance of the elastic fins 311 to the adapter rod 31 passing through the mounting bracket 4.

[0031] In addition, the connection between the adapter rod 31 and the gear 32 can also be riveted or threaded.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
