Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamps, and in particular to a coupling mechanism for vehicle lamps. Background Art

[0002] Traditional joint debugging organizations mainly include the following core issues:

[0003] 1. Size limitation: The two brackets in a traditional joint adjustment mechanism are typically no longer than 100 mm, which limits its application. For example, when the lens is mounted far from the adjustment point, the mechanism cannot effectively adjust the optical path due to insufficient torque or low transmission efficiency.

[0004] 2. Limited styling: The dimming range (dimming envelope) of traditional joint adjustment mechanisms is large, which requires a larger gap between the headlights and the body or other components. The larger gap requirement severely limits the design freedom of the headlights and body styling. The large gap destroys the streamlined design of the body and affects the appearance. The volume of the headlight assembly is forced to increase, which makes it difficult to meet the industry trend of compact headlights.

[0005] 3. Increased cost and weight: To circumvent the above problems, a headlight is sometimes split into two independent lights (A light and B light), but this splitting solution will significantly increase the cost and weight of the system. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0007] To this end, the present invention proposes a joint dimming mechanism for vehicle lights, which realizes synchronous dimming of upper and lower lenses, breaking through the traditional distance limitation. The dimming envelope is the same as the dimming envelope of a single dimming bracket.

[0009] The beneficial effects of the present invention are that the vehicle lamp joint adjustment mechanism of the present invention has the following advantages:

[0053] A vehicle lamp adjustment mechanism according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0054] See Figure 1-14 The present invention provides a joint dimming mechanism for a vehicle light, comprising a bracket 1, a linkage bracket 2, a first dimming bracket 3, a second dimming bracket 4, a manual dimming shaft 5 and a dimming motor 6.

[0055] The bracket 1 includes a ball seat 101 , a rotating shaft 102 , a first sliding groove 103 and a second sliding groove 104 .

[0056] The linkage bracket 2 includes a connecting seat 201 , a first sliding shaft 202 , a first guide shaft 203 , a second sliding shaft 204 and a second guide shaft 205 .

[0057] The first dimming bracket 3 includes a first set of rotating shafts 301 and a first guide groove 302 .

[0058] The second dimming bracket 4 includes a second set of rotating shafts 401 and a second guide groove 402 .

[0059] The manual dimming axis 5 includes a first dimming axis 501 , a second dimming axis 502 , a first matching bracket 503 and a second matching bracket 504 .

[0060] The dimming motor 6 includes a dimming bracket 601 , a motor 602 and a conductive structure 603 .

[0061] The bracket 1 is connected to the vehicle lamp housing. Specifically, the bracket 1 is rotatably connected to the vehicle lamp housing via two coaxially arranged rotating shafts.

[0062] A first sliding shaft 202 is provided between the linkage bracket 2 and the first sliding groove 103 on the bracket 1 , and the first end of the linkage bracket 2 is slidably engaged with the first sliding groove 103 on the bracket 1 through the first sliding shaft 202 .

[0063] A second sliding shaft 204 is provided between the linkage bracket 2 and the second sliding groove 104 on the bracket 1 , and the second end of the linkage bracket 2 is slidably engaged with the second sliding groove 104 on the bracket 1 via the second sliding shaft 204 .

[0064] A connecting base 201 is provided on the linkage bracket 2 , and the connecting base 201 is connected to the dimming motor 6 .

[0065] A motor 602 is installed on the dimming bracket 601 of the dimming motor 6, and a ball head is installed at the power output end of the motor 602. The ball head is clamped in the conductive structure 603 of the dimming motor 6, and the end of the conductive structure 603 away from the dimming bracket 601 is rotated and clamped in the connecting seat 201 of the linkage bracket 2. That is, the motor 602 is arranged on one side of the dimming bracket 601 of the dimming motor 6, and the ball head is installed at the output end of the motor 602. The ball head is clamped in the conductive structure 603, and the other side of the conductive structure 603 is rotated and clamped in the connecting seat 201. When the dimming bracket 601 moves longitudinally, the conductive structure 603 drives the linkage bracket 2 to move up and down.

[0066] Two rotating shafts are set between the first dimming bracket 3 and the bracket 1, and the two rotating shafts are on the same axis. Specifically, the two rotating shafts constitute a first group of rotating shafts 301. The first dimming bracket 3 is rotatably connected to the bracket 1 through the first group of rotating shafts 301, and the first dimming bracket 3 is provided with a first guide groove 302 that slides with the first guide shaft 203 on the linkage bracket 2, that is, the first dimming bracket 3 and the linkage bracket 2 are connected to the first guide shaft 203 through the first guide groove 302.

[0067] Two rotating shafts are set between the second dimming bracket 4 and the bracket 1, and the two rotating shafts are on the same axis. Specifically, the two rotating shafts constitute a second group of rotating shafts 401. The second dimming bracket 4 is rotatably connected to the bracket 1 through the second group of rotating shafts 401, and the second dimming bracket 4 is provided with a second guide groove 402 that slides with the second guide shaft 205 on the linkage bracket 2, that is, the second dimming bracket 4 and the linkage bracket 2 are connected to the second guide shaft 205 through the second guide groove 402.

[0068] The first dimming bracket 3 and the second dimming bracket 4 rotate around the first set of rotating shafts 301 and the second set of rotating shafts 401 respectively, thereby realizing up and down dimming of the lens module.

[0069] The manual dimming shaft 5 includes a first bevel gear and a second bevel gear that are meshed with each other. The first bevel gear is fixed to the first dimming shaft 501, and the second bevel gear is fixed to the second dimming shaft 502; the first matching bracket 503 is installed on the second dimming shaft 502 and is close to one end of the second bevel gear, and the second matching bracket 504 is threadedly installed on the second dimming shaft 502 and is away from one end of the second bevel gear. The end of the second matching bracket 504 away from the second dimming shaft 502 is rotatably connected to the ball seat 101 of the bracket 1 through the ball head sleeve 9, that is, the bracket 1 and the manual dimming shaft 5 are rotatably connected through the ball seat 101.

[0070] The first dimming axis 501 of the manual dimming axis 5 is meshed with the second dimming axis 502 through a bevel gear. The second dimming axis 502 is connected to the first matching bracket 503 and the second matching bracket 504. When the second dimming axis 502 rotates, the length of the second matching bracket 504 is adjusted to screw into the second matching bracket 504, so as to realize the forward and backward movement of the second matching bracket 504. A ball head is set at one end of the second matching bracket 504, which is rotated and clamped in the ball seat 101 of the bracket 1 through the ball head sleeve 9. When the second matching bracket 504 moves forward and backward, the bracket 1 will rotate left and right, thereby realizing the left and right dimming of the lens module. When the bracket 1 rotates left and right, the ball head of the dimming motor 6 can move in the slide groove of the conductive structure 603.

[0071] Preferably, the two rotating shafts 102 between the bracket 1 and the lamp housing are each formed by a connector 7 and a screw 8, and the axes of the two rotating shafts 102 coincide, that is, the two rotating shafts 102 are arranged on the same axis. The rotating shafts 102 formed by the connector 7 and screw 8 provide a detachable rigid connection, easy maintenance, strong fatigue resistance, and improved connection reliability.

[0072] Preferably, the conductive structure 603 is a U-shaped slot member with a rotation fulcrum at each end. The rotation fulcrum is rotatably embedded in the slot of the connecting base 201. The rotation fulcrum design of the U-shaped conductive structure 603 compensates for axial deviation of the dimming bracket 601, prevents movement jamming, and optimizes movement freedom.

[0073] Preferably, the first guide shaft 203 on the linkage bracket 2 is disposed in the first guide slot 302 of the first dimming bracket 3, and the second guide shaft 205 on the linkage bracket 2 is disposed in the second guide slot 402 of the second dimming bracket 4. The first guide shaft 203 and the second guide shaft 205 respectively control the two dimming brackets, i.e., independent guide control is adopted to avoid motion interference and ensure dimming synchronization of the dual-lens module.

[0074] Preferably, the first and second chute 103, 104 are vertically aligned and parallel to each other. The parallel structure of the first and second chute 103, 104 constrains the linkage bracket 2 to move only in the vertical direction, eliminating lateral deviation, improving vertical adjustment linearity, and achieving precise vertical guidance.

[0075] Preferably, the ball seat 101 is provided on the side wall of the bracket 1, and the ball head cover 9 covers the ball head of the second supporting bracket 504 and forms a ball hinge with the ball seat 101. The ball hinge formed by the ball head cover 9 and the ball seat 101 allows the second supporting bracket 504 to adaptively adjust its angle during the push-pull process, avoiding mechanical stagnation and achieving multi-directional rotation compatibility.

[0076] Preferably, a ball head anti-detachment ring is provided between the dimming bracket 601 of the dimming motor 6 and the motor 602. The ball head anti-detachment ring prevents the dimming bracket 601 and the motor 602 from detaching in a vibration environment, thereby improving driving safety and reliability.

[0077] Preferably, a sealed dust cover is provided at the meshing point of the first dimming axis 501 and the second dimming axis 502. The sealed dust cover protects the meshing point of the bevel gears, preventing dust / water vapor from intruding and causing thread jamming, thereby extending outdoor service life and improving environmental adaptability.

[0078] Preferably, the first guide groove 302 and the second guide groove 402 are both arcuate grooves, and their centers of curvature correspond to the axes of the first set of rotating shafts 301 and the second set of rotating shafts 401, respectively. The centers of curvature of the arcuate first guide groove 302 and the arcuate second guide groove 402 correspond to the rotational axes, allowing the first guide shaft 203 and the second guide shaft 205 to move along a tangent line, reducing sliding friction losses and achieving motion trajectory matching.

[0079] Preferably, the threads of the first supporting bracket 503 and the second dimming shaft 502 are self-locking. The self-locking thread structure prevents the second dimming shaft 502 from accidentally rotating due to vehicle vibration, ensuring that the left and right dimming angles are permanently stable.

[0080] The vehicle lamp joint adjustment mechanism of the present invention has the following advantages:

[0081] 1. The present invention uses the linkage bracket 2 to synchronously drive the dual dimming brackets (the first dimming bracket 3 and the second dimming bracket 4) to rotate, breaking through the 100mm spacing limit of the traditional design, and is compatible with various headlight shapes to meet more styling requirements;

[0082] Second, the present invention overcomes the disadvantage of the large dimming envelope of the traditional multi-module bracket. The optimized transmission structure makes the overall dimming envelope basically the same as the traditional single-module dimming solution, effectively reducing space occupation;

[0083] 3. Dual dimming decoupling:

[0084] ① Electric up and down dimming: the motor 602 in the dimming motor 6 works → the dimming bracket 601 moves longitudinally → the conductive structure 603 also moves longitudinally → the linkage bracket 2 realizes vertical movement → the guide shaft drives the dimming bracket to rotate (the first guide shaft 203 drives the first dimming bracket 3 to rotate, and the second guide shaft 205 drives the second dimming bracket 4 to rotate). The movement paths are independent to avoid interference with manual dimming;

[0085] ② Manual left and right dimming: the first bevel gear and the second bevel gear engage → the thread pushes the second supporting bracket 504 → the ball head on the second supporting bracket 504 rotates → the bracket 1 rotates as a whole, with a short mechanical transmission chain and high precision.

[0086] 4. Improved Stability: Bracket 1 is connected to the headlight housing via two coaxial rotating shafts 102. The first dimming bracket 3 is connected to bracket 1 via a first set of rotating shafts 301, and the second dimming bracket 4 is connected to bracket 1 via a second set of rotating shafts 401. The dual coaxial design suppresses vibration and offset.

[0087] 5. The modular design used in the present invention realizes the compact arrangement of multiple lamp groups and provides technical support for the development of innovative vehicle lamp shapes: structural integration, by clearly defining the six core components and their subcomponents (such as the bracket 1, the linkage bracket 2, the first dimming bracket 3, the second dimming bracket 4, the manual dimming shaft 5 and the dimming motor 6) (such as the bracket 1 including the ball seat 101 / slide groove, the linkage bracket 2 including the double sliding shafts / double guide shafts, etc.), a highly modular design of the mechanism is achieved, reducing the complexity of assembly.

[0088] 6. The present invention satisfies the functionality of the linkage bracket while reducing the weight and cost of the module through structural design.

[0089] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
