Description

Technical Field

[0001] This application relates to the field of vehicle headlight adjustment technology, and in particular to a dimming structure and a vehicle headlight. Background Technology

[0002] The beam angle of a vehicle's headlights varies depending on the vehicle's load and road conditions. If the headlight beam is not properly positioned, it can impair the driver's vision and increase the risk of traffic accidents.

[0003] Typically, the lighting module inside a vehicle headlight has a dimming mechanism, which includes a motor and an adjustment bracket. The motor drives the lighting module to move through the adjustment bracket, thereby adjusting the vertical angle of the headlight beam.

[0004] However, with the rapid development of the automotive industry, vehicle models are becoming increasingly novel, and each model's appearance is more futuristic and minimalist. This extreme minimalism in the exterior design further compresses the space inside the headlights, thus restricting the installation of the motor. This can lead to motor interference or output bias after installation, ultimately affecting the reliability of the dimming structure. Utility Model Content

[0005] This application provides a dimming structure and a vehicle light, aiming to improve the problem of low reliability of the dimming structure due to the limitation of motor installation.

[0006] The specific technical solution is as follows:

[0007] An embodiment of the first aspect of this application provides a dimming structure for a vehicle lamp, the vehicle lamp including a lamp housing and an illumination module disposed within the lamp housing, the dimming structure including: at least one driving member for connecting to the lamp housing; a dimming bracket for fixedly connecting to the illumination module, the dimming bracket including spaced-apart fulcrum portions and at least one rotating portion, the fulcrum portions being connected to the lamp housing; at least one adapter, each of the driving members being connected to a rotating portion via an adapter, the driving member being configured to drive the adapter to move along a first direction, so that the dimming bracket drives the illumination module to deflect at an angle around a preset axis, the first direction being the light emission direction of the vehicle lamp.

[0008] The dimming structure of this application embodiment connects the driver and the dimming bracket by using an adapter. The driver is positioned along a first direction, fully utilizing the depth space inside the headlight along the light-emitting direction—an area that is difficult to compress in a minimalist design. Furthermore, the driver is connected to the dimming bracket via the adapter, whose shape can be flexibly designed to allow the driver to be placed within the available space of the lamp housing, avoiding areas with densely packed lighting modules or other components. Even if the internal space of the lamp housing is irregular, the adapter's shape design ensures sufficient installation space for the driver, guaranteeing effective transmission of output force and preventing mechanical jamming or wear due to offset. This reduces the probability of driver interference or insufficient installation space, thereby improving the reliability and stability of the dimming structure.

[0009] In some embodiments, the dimming bracket includes a bracket body and a through hole provided on the bracket body, the lighting module passes through the through hole, and the edge of the bracket body is provided with a first corner and a second corner, the second corner being located on one side of the first corner along a second direction;

[0010] The number of the driving component, the rotating part, and the adapter is one each. The fulcrum is located at the first corner, the rotating part is located at the second corner, and the second direction is perpendicular to the first direction.

[0011] This design has two advantages. First, the fulcrum and rotating part are located at the corner of the bracket body, which makes use of the fragmented space at the corner of the lamp housing, thereby improving the space utilization rate inside the lamp housing and thus improving the structural compactness of the vehicle lamp. Second, it also helps to balance cost and ease of adjustment.

[0012] In some embodiments, the number of the driving member, the rotating part, and the adapter is two, the two driving members are a first driving member and a second driving member, the two rotating parts are a first rotating part and a second rotating part, and the two adapters are a first adapter and a second adapter.

[0013] The first driving component is configured to drive the first adapter to move along a first direction, so that the dimming bracket drives the lighting module to deflect at an angle about a third direction as the axis;

[0014] The second driving component is configured to drive the second adapter to move along the first direction, so that the dimming bracket causes the lighting module to deflect at an angle about the second direction as the axis, wherein the second direction, the third direction and the first direction are perpendicular to each other.

[0015] This configuration allows the dimming structure to achieve bidirectional beam adjustment of the lighting module through two drive components, improving the convenience and intelligence of headlight adjustment. Furthermore, the layout of both drive components via adapters ensures sufficient installation space, guarantees effective transmission of output force, and prevents mechanical jamming or wear due to misalignment. This also reduces the probability of drive component interference or insufficient installation space, thereby improving the reliability and stability of the dimming structure.

[0016] In some embodiments, the dimming bracket includes a bracket body and a through hole provided on the bracket body, the lighting module passes through the through hole, and the edge of the bracket body is provided with a first corner, a second corner and a third corner, the second corner is located on one side of the first corner along the second direction, and the third corner is located on one side of the first corner along the third direction.

[0017] The fulcrum is located at the first corner, the first rotating part is located at the second corner, and the second rotating part is located at the third corner.

[0018] This design has two advantages. First, the second and third corners extend from the first corner along the second and third directions, respectively, allowing the two rotating parts to fully utilize the redundant space at the corners of the lamp housing. This improves the space utilization rate inside the lamp housing and, consequently, enhances the structural compactness of the vehicle lamp. Second, it also helps to further improve the convenience and automation of the dimming structure.

[0019] In some embodiments, the bracket body is provided with a plurality of first weight-reduction cavities. This arrangement facilitates the lightweighting of the dimming structure, thereby reducing the weight of the vehicle headlight.

[0020] In some embodiments, the bracket body is provided with a plurality of mounting holes for connecting to the lighting module. This arrangement helps to improve the reliability and stability of the connection between the bracket body and the lighting module.

[0021] In some embodiments, the adapter is provided with a plurality of second weight-reduction cavities. This configuration facilitates the lightweighting of the dimming structure, thereby reducing the weight of the vehicle headlights.

[0022] In some embodiments, the adapter includes a main body and an extension, the main body being detachably connected to the rotating part, the extension being located on the side of the main body away from the lighting module, and the extension being detachably connected to the output end of the driver.

[0023] This design offers several advantages. First, it allows for flexible design of the extension's shape and structure based on the internal space of the lamp housing, preventing interference between the driver and the lamp housing or other components during installation and movement. This enhances the reliability, stability, and versatility of the dimming structure. Second, the detachable connections between the main body and the rotating part, as well as between the extension and the driver's output end, further improve the efficiency and convenience of assembly and maintenance, while reducing costs.

[0024] In some embodiments, the rotating part is an elastic buckle with an arc-shaped wall inside, and the main body is provided with a first ball-head locking post, which engages with the elastic buckle.

[0025] This design simplifies structural design, saves space, and reduces costs. It also improves the flexibility of rotation for both components. Furthermore, the elastic snap-fit ​​and the first ball-head locking post allow for disassembly or assembly with only axial force, eliminating the need for tools and thus improving assembly and maintenance efficiency.

[0026] In some embodiments, the extension is provided with a first connection hole, a first ball joint seat is provided in the first connection hole, and the output end of the drive member is provided with a second ball joint post. The drive member is connected to the first ball joint seat through the second ball joint post.

[0027] This design, on the one hand, avoids the jamming or stress concentration caused by rigid connections, thus improving the smoothness of movement. On the other hand, the aforementioned snap-fit ​​structure can also reduce the requirements for assembly precision and improve assembly tolerance. In addition, only axial force is needed for disassembly or assembly, without the need for tools, which also helps to improve assembly and maintenance efficiency.

[0028] In some embodiments, the fulcrum portion is a second connecting hole, and a second ball joint is provided in the second connecting hole. The second ball joint is connected to the lamp housing by a ball head screw.

[0029] This design allows for both the fixing and relative rotation of the lamp housing and the dimming bracket via a snap-fit ​​connection, which helps to save components, simplify the structure, and improve the efficiency and convenience of assembly and maintenance of the dimming structure.

[0030] In some embodiments, the dimming structure further includes an adjustment member connected to the output end of the driver, the adjustment member being configured to drive the output end of the driver to move under the action of an external force, thereby driving the adapter to move along the first direction.

[0031] This configuration allows for redundant design, which in turn improves the reliability of the dimming structure under extreme conditions.

[0032] An embodiment of the second aspect of this application provides a vehicle lamp, including a lamp housing, an illumination module disposed within the lamp housing, and a dimming structure as described in the first aspect, wherein the driving member is connected to the lamp housing, the dimming bracket is fixedly connected to the illumination module, and the fulcrum portion is connected to the lamp housing.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0051] like Figures 1 to 4As shown, in a first aspect, embodiments of this application provide a dimming structure 10 for a vehicle lamp. The vehicle lamp includes a lamp housing (not shown) and an illumination module 20 disposed within the lamp housing. The dimming structure 10 includes at least one driving member 100, a dimming bracket 200, and at least one adapter 300. The driving member 100 is used to connect to the lamp housing, and the dimming bracket 200 is used to fixally connect to the illumination module 20. The dimming bracket 200 includes a fulcrum portion 201 spaced apart and at least one rotating portion 202. The fulcrum portion 201 is used to connect to the lamp housing. Each driving member 100 is connected to a rotating portion 202 through an adapter 300. The driving member 100 is configured to drive the adapter 300 to move along a first direction X, so that the dimming bracket 200 drives the illumination module 20 to deflect at an angle around a preset axis. The first direction X is the light emission direction of the vehicle lamp.

[0052] The dimming structure 10 includes at least one drive element 100, a dimming bracket 200, and at least one adapter 300. The drive element 100 is the power source of the dimming structure 10, used to provide linear motion output along a first direction X (the light output direction of the vehicle lamp). The drive element 100 is rigidly connected to the lamp housing to ensure that it has no displacement during movement and that the output force is stable.

[0053] The dimming bracket 200 is the core transmission component connecting the lighting module 20 and the lamp housing. The fulcrum 201 is the rotation fulcrum of the dimming bracket 200. On one hand, the fulcrum 201 connects the dimming bracket 200 and the lamp housing; on the other hand, the dimming bracket 200 can rotate relative to the lamp housing with the fulcrum 201 as the fulcrum. The rotating part 202 is the force-bearing point of the dimming bracket 200. A lever structure can be formed between the rotating part 202 and the fulcrum 201, with the distance between them being the lever arm. For example, if there is a first distance between the rotating part 202 and the fulcrum 201, and the length by which the driving member 100 pushes the rotating part 202 to move along the first direction X is a second distance, then the deflection angle of the lighting module 20 can be approximated as the arctangent of the ratio of the second distance to the first distance. Therefore, by optimizing the stroke of the driving member 100 and the distance between the rotating part 202 and the fulcrum 201, the stroke range of the deflection angle of the lighting module 20 can be flexibly adjusted.

[0054] The adapter 300 is a connection and conversion component between the drive unit 100 and the dimming bracket 200. The output end of the drive unit 100 is connected to the rotating part 202 of the dimming bracket 200 through the adapter 300. The adapter 300 mainly serves to adapt to the internal space of the vehicle headlight and realize the effective transmission of power.

[0055] The following explains the specific principle of headlight adjustment: In the initial state, the driver 100 is in the initial position, and the lighting module 20 is within the reference illumination range. If headlight adjustment is required, the driver 100 is activated, and its output end moves linearly along the light emission direction (first direction X). The linear movement of the driver 100 is transmitted to the rotating part 202 of the dimming bracket 200 through the adapter 300. Subsequently, the rotating part 202 receives a force (push or pull). Since the fulcrum 201 of the dimming bracket 200 is fixed to the lamp housing, the rotating part 202 and the fulcrum 201 form a lever. The force applied to the rotating part 202 generates a torque around the fulcrum part 201. It can be understood that if the rotating part 202 is located on the side of the fulcrum part 201 in the vertical direction, the dimming bracket 200 will cause the lighting module 20 to adjust its angle in the vertical direction; if the rotating part 202 is located on the side of the fulcrum part 201 in the horizontal direction, the dimming bracket 200 will cause the lighting module 20 to adjust its angle in the horizontal direction. Thus, the direction of the beam emitted by the lighting module 20 changes, thereby achieving the dimming function of the vehicle lights. Here, the vertical direction refers to the vehicle's vertical direction (height direction), and the horizontal direction refers to the vehicle's horizontal direction.

[0056] The dimming structure 10 of this embodiment connects the driver 100 and the dimming bracket 200 via an adapter 300. The driver 100 is positioned along a first direction X, fully utilizing the interior space of the headlight along the light-emitting direction—an area that is difficult to compress in a minimalist design. Furthermore, the driver 100 is connected to the dimming bracket 200 via the adapter 300. The shape of the adapter 300 can be flexibly designed to guide the driver 100 into the available space inside the headlight housing, avoiding areas densely populated with the lighting module 20 or other components. Even if the interior space of the headlight housing is irregular, the adapter 300's shape design ensures sufficient installation space for the driver 100, ensuring effective transmission of output force and preventing mechanical jamming or wear due to offset. This reduces the probability of interference or insufficient installation space for the driver 100, thereby improving the reliability and stability of the dimming structure 10.

[0057] Furthermore, in related technologies, if space is limited, customized motors or brackets need to be designed, increasing the complexity of production and maintenance. This application, however, uses an adapter 300 for transitional connection, allowing the drive component 100 and dimming bracket 200 to be produced in a standardized manner. This reduces the need for customized components, lowers manufacturing costs, and simplifies maintenance. Moreover, for different vehicle models, the dimming structure 10 can be universally applicable simply by flexibly designing the shape of the adapter 300. This also improves the adaptability and versatility of the dimming structure 10, accommodating the personalized designs of different vehicle models.

[0058] Furthermore, through the lever design of the fulcrum 201 and the rotating part 202, this application can transform the small movement of the driving component 100 into a large-range angle adjustment of the lighting module 20 within a limited space by amplifying the lever arm. This does not require increasing the size of the driving component, but can still meet the adjustment requirements, taking into account both the space compression requirements and the large adjustment range.

[0059] like Figure 1 , Figures 3 to 6 As shown, in some embodiments, the dimming bracket 200 includes a bracket body 210 and a through hole 203 provided on the bracket body 210. The lighting module 20 passes through the through hole 203. The edge of the bracket body 210 is provided with a first corner 211 and a second corner 212. The second corner 212 is located on one side of the first corner 211 along the second direction Z. The number of the driving member 100, the rotating part 202 and the adapter 300 is one. The fulcrum part 201 is provided at the first corner 211 and the rotating part 202 is provided at the second corner 212. The second direction Z is perpendicular to the first direction X.

[0060] This embodiment presents a specific structure for the dimming structure 10 when there is only one drive component 100, one adapter 300, and one rotating part 202. The bracket body 210 can be made of engineering plastics, aluminum alloy, or other materials, balancing lightweight and strength. The lighting module 20 passes through the through hole 203, allowing the dimming bracket 200 to synchronously drive the lighting module 20 to rotate. This through-hole method improves the reliability and stability of the fixed connection between the two. Furthermore, it saves space and improves the space utilization rate inside the lamp housing.

[0061] The bracket body 210 has a first corner 211 and a second corner 212 on its edge. The first corner 211 and the second corner 212 are corner areas where the edge contour direction of the bracket body 210 changes. The second corner 212 is located on one side of the first corner 211 along the second direction Z. The fulcrum part 201 is located at the first corner 211, and the rotating part 202 is located at the second corner 212. In this case, the drive member 100 is connected to the rotating part 202 of the second corner 212 of the dimming bracket 200 through the adapter 300, while the fulcrum part 201 of the first corner 211 is connected to the lamp housing. The second direction Z can be the vertical direction (height direction) or the horizontal direction of the vehicle. When the second direction Z is the vertical direction of the vehicle, the drive member 100 pushes the rotating part 202 through the adapter 300, so that the dimming bracket 200 can be deflected at an angle with the fulcrum part 201 as the rotation point and the horizontal direction as the rotation axis, thereby enabling the lighting module 20 to adjust the beam in the vertical direction. When the second direction Z is the left and right direction of the vehicle, the drive unit 100 pushes the rotating part 202 through the adapter 300, so that the dimming bracket 200 can be deflected at an angle with the fulcrum part 201 as the rotation point and the up and down direction as the rotation axis, thereby enabling the lighting module 20 to adjust the beam in the left and right directions.

[0062] This arrangement has two advantages. First, the fulcrum 201 and the rotating part 202 are located at the corner of the bracket body 210, which utilizes the fragmented space at the corner of the lamp housing, thereby improving the space utilization rate inside the lamp housing and thus improving the structural compactness of the vehicle lamp. Second, the lighting module 20 uses the drive unit 100 for beam adjustment in one direction, while the manual dimming unit 600 in related technologies can still be used for beam adjustment in the other direction. For example, see reference... Figure 1 and Figure 7 The dimming mechanism is adjusted vertically via the drive unit 100 and the adapter 300, and horizontally via the manual dimming unit 600. This balances cost and ease of adjustment. The manual dimming unit is a component that provides driving force to the dimming bracket 200 through manually applied force.

[0063] Please refer to Figure 1 , Figure 2 and Figure 5In some embodiments, there are two driving members 100, two rotating parts 202, and two adapters 300. The two driving members 100 are a first driving member 100a and a second driving member (not shown in the figure), the two rotating parts 202 are a first rotating part 202a and a second rotating part 202b, and the two adapters 300 are a first adapter 300a and a second adapter (not shown in the figure). The first driving member 100a is configured to drive the first adapter 300a to move along the first direction X, so that the dimming bracket 200 drives the lighting module 20 to deflect at an angle about the third direction Y as the axis. The second driving member is configured to drive the second adapter to move along the first direction X, so that the dimming bracket 200 drives the lighting module 20 to deflect at an angle about the second direction Z as the axis. The second direction Z, the third direction Y, and the first direction X are perpendicular to each other.

[0064] This embodiment presents a specific adjustment method for the dimming structure 10 when there are two drive components 100, two adapter components 300, and two rotating parts 202. Specifically, one of the second direction Z and the third direction Y can be the vertical direction of the vehicle, and the other can be the horizontal direction of the vehicle. The following explanation uses the second direction Z as the vertical direction of the vehicle and the third direction Y as the horizontal direction of the vehicle as an example.

[0065] In this embodiment, the first driving member 100a is connected to the first rotating part 202a of the dimming bracket 200 via the first adapter 300a. A first rotating arm is formed between the fulcrum part 201 and the first rotating part 202a, enabling the lighting module 20 to adjust the beam in the vertical direction. The second driving member is connected to the second rotating part 202b of the dimming bracket 200 via the second adapter. A second rotating arm is formed between the fulcrum part 201 and the second rotating part 202b, enabling the lighting module 20 to adjust the beam in the horizontal direction.

[0066] This configuration allows the dimming structure 10 to achieve bidirectional beam adjustment of the lighting module 20 via two driving components 100. The first driving component 100a deflects the dimming bracket 200 around a third direction Y to achieve vertical dimming, compensating for changes in vehicle posture when fully loaded / unloaded. The second driving component deflects the dimming bracket 200 around a second direction Z to achieve horizontal dimming, enabling adaptive steering in conjunction with steering wheel angles and significantly improving driving safety in complex road conditions. Compared to related technologies where a single driving component achieves unidirectional adjustment and a manual adjustment component achieves adjustment in the other direction, this design enhances the convenience and intelligence of headlight adjustment. Furthermore, the layout of both driving components via adapters ensures sufficient installation space for the driving components 100, ensuring effective transmission of output force and preventing mechanism jamming or wear due to offset. This also reduces the probability of interference or insufficient installation space for the driving components 100, thereby improving the reliability and stability of the dimming structure 10.

[0067] Furthermore, in some embodiments, the edge of the support body 210 is provided with a first corner 211, a second corner 212 and a third corner 213. The second corner 212 is located on one side of the first corner 211 along the second direction Z, and the third corner 213 is located on one side of the first corner 211 along the third direction Y. The fulcrum part 201 is provided at the first corner 211, the first rotating part 202a is provided at the second corner 212, and the second rotating part 202b is provided at the third corner 213.

[0068] Among them, the first corner 211, the second corner 212 and the third corner 213 are all corner structures on the edge of the bracket body 210. The first corner 211 is a common fulcrum. The three form an "L" shaped layout. The first adapter 300a connects the first drive 100a and the first rotating part 202a of the second corner 212. The second adapter connects the second drive and the second rotating part 202b of the third corner 213. Thus, the beam adjustment of the lighting module 20 in both directions is realized.

[0069] This configuration has several advantages. First, the second corner 212 and the third corner 213 extend from the first corner 211 along the second direction Z and the third direction Y, respectively. This allows the two rotating parts to fully utilize the redundant space at the corners of the lamp housing, thereby improving the space utilization rate inside the lamp housing and thus enhancing the structural compactness of the vehicle lamp. Second, it also helps to further improve the convenience and automation of the dimming structure 10.

[0070] It should be noted that the above only illustrates one way in which the rotating part 202 and the fulcrum part 201 are arranged on the dimming bracket 200, but it is not the only limitation on the arrangement position of the rotating part 202 and the fulcrum part 201. As long as the rotating part 202 can rotate around the fulcrum part 201 with the second direction Z or the third direction Y as the axis, it is acceptable.

[0071] like Figure 4 and Figure 6 As shown, in some embodiments, the bracket body 210 is provided with a plurality of first weight-reduction cavities 214. This arrangement is beneficial for achieving a lightweight dimming structure 10, thereby helping to reduce the weight of the vehicle lamp.

[0072] like Figure 5 and Figure 6 As shown, in some embodiments, the bracket body 210 is provided with a plurality of mounting holes 215 for connecting to the lighting module 20. This arrangement helps to improve the reliability and stability of the connection between the bracket body 210 and the lighting module 20.

[0073] like Figure 4As shown, in some embodiments, the adapter 300 is provided with a plurality of second weight-reduction cavities 301. This arrangement is beneficial for achieving a lightweight dimming structure 10, thereby helping to reduce the weight of the vehicle lamp.

[0074] like Figures 1 to 4 As shown, in some embodiments, the adapter 300 includes a main body 310 and an extension 320. The main body 310 is detachably connected to the rotating part 202, and the extension 320 is located on the side of the main body 310 away from the lighting module 20. The extension 320 is detachably connected to the output end of the drive member 100.

[0075] This embodiment presents a specific structure of the adapter 300. The adapter 300 includes a main body 310 and an extension 320. The main body 310 is the part of the adapter 300 that connects to the rotating part 202 of the dimming bracket 200. That is, the structure of the main body 310 needs to be adapted to the structure of the rotating part 202 of the dimming bracket 200.

[0076] The extension 320 is a portion that extends from the main body 310 toward the side away from the lighting module 20. This portion can introduce the connection position of the driver 100 into a suitable position inside the lamp housing, so as to avoid problems such as interference between the driver 100 and the lamp housing or output bias.

[0077] This design offers several advantages. First, given the differences in internal space between headlights in different vehicle models, dividing the adapter 300 into a main body 310 and an extension 320 allows for the connection between the drive component 100 and the rotating part 202. Furthermore, the shape and structure of the extension 320 can be flexibly designed according to the internal space of the lamp housing, ensuring that the drive component 100 does not interfere with the lamp housing or other components during installation and movement. This improves the reliability, stability, and versatility of the dimming structure 10. Second, the main body 310 and the rotating part 202, as well as the extension 320 and the output end of the drive component 100, are detachably connected. This further enhances the efficiency and convenience of assembly and maintenance of the dimming structure 10, reducing costs.

[0078] like Figures 1 to 6 As shown, in some embodiments, the rotating part 202 is an elastic buckle, the elastic buckle has an arc-shaped wall 2021 inside, and the main body 310 has a first ball head locking post 311, which is engaged with the elastic buckle.

[0079] The first ball-head locking post 311 refers to a connecting post with a ball-head shape at its end. The first ball-head locking post 311 of the main body 310 can be inserted into the elastic buckle, so that the ball head of the first ball-head locking post 311 makes surface contact with the arc-shaped wall surface 2021. This allows for both a detachable connection between the rotating part 202 and the main body 310, and a rotational connection between the rotating part 202 and the main body 310, ensuring smooth adjustment.

[0080] This design offers several advantages. First, the elastic buckle and the bracket body 210 are integrally formed, as are the first ball-head locking post 311 and the main body 310 of the adapter 300. This simplifies the structural design, saves space, and reduces costs. Second, the spherical fit between the curved wall surface 2021 and the first ball-head locking post 311 allows for the compensation of assembly errors through the slight sliding of the ball head within the curved surface, thereby improving the flexibility of their rotation. Furthermore, the engagement of the elastic buckle and the first ball-head locking post 311 requires only axial force for disassembly or assembly, eliminating the need for tools and further improving assembly and maintenance efficiency.

[0081] It is understood that the main body 310 and the rotating part 202 can also be detachably connected in other ways, and this application does not limit this.

[0082] like Figures 1 to 4 As shown, in some embodiments, the extension 320 is provided with a first connecting hole 321, a first ball joint holder 330 is provided in the first connecting hole 321, and a second ball joint post 101 is provided at the output end of the drive member 100. The drive member 100 is connected to the first ball joint holder 330 through the second ball joint post 101.

[0083] A ball head holder refers to an elastic snap-fit ​​structure with a spherical receiving space inside. A first ball head holder 330 is provided in the first connecting hole 321. For example, a slot can be provided in the first connecting hole 321, and a locking block can be provided on the outer surface of the first ball head holder 330 (the surface near the inner wall of the first connecting hole 321). The first ball head holder 330 is snapped onto the slot in the first connecting hole 321 by the locking block, thereby realizing the detachable connection between the two.

[0084] The second ball-head locking post 101 refers to a connecting post with a ball-head shape at its end. The ball head of the second ball-head locking post 101 can be inserted into the spherical buckle of the first ball-head locking seat 330, so that the second ball-head locking post 101 can realize both the detachable connection between the driving member 100 and the extension 320 and the rotational connection between the driving member 100 and the extension 320, ensuring the smooth power transmission of the driving member 100.

[0085] This design eliminates motion interference between the drive component 100 and the adapter 300, avoiding jamming or stress concentration caused by rigid connections, thus improving smoothness of movement. Furthermore, the aforementioned snap-fit ​​structure reduces the requirements for assembly precision and increases assembly tolerance. In addition, only axial force is needed for disassembly or assembly, eliminating the need for tools, which further improves assembly and maintenance efficiency.

[0086] like Figure 1 and Figure 2 As shown, in some embodiments, the fulcrum 201 is a second connecting hole, and a second ball head holder 2011 is provided in the second connecting hole. The second ball head holder 2011 is connected to the lamp housing by a ball head screw 700.

[0087] The structure of the second ball joint holder 2011 can be the same as that of the first ball joint holder 330, and the second ball joint holder 2011 is also snapped into the second connecting hole. In this embodiment, one end of the ball head screw 700 is fastened to the lamp housing, and the ball head of the ball head screw 700 can be inserted into the spherical buckle of the second ball joint holder 2011, so that the fulcrum part 201 can not only realize the connection between the lamp housing and the dimming bracket 200, but also allow the dimming bracket 200 to have the freedom of rotation.

[0088] This design allows for both the fixing and relative rotation of the lamp housing and the dimming bracket 200 via a snap-fit ​​connection, thereby saving components, simplifying the structure, and improving the efficiency and convenience of assembling and maintaining the dimming structure 10.

[0089] like Figure 1 and Figure 2 As shown, in some embodiments, the dimming structure 10 further includes an adjustment member 400 connected to the output end of the drive member 100. The adjustment member 400 is configured to drive the output end of the drive member 100 to move under the action of an external force, thereby driving the adapter 300 to move along the first direction X.

[0090] In this embodiment, the dimming structure 10 also includes an adjustment element 400, which can manually drive the output end of the drive element 100 to move, thereby realizing the beam adjustment of the vehicle headlight. This configuration enables redundant design, which helps to improve the reliability of the dimming structure 10 under extreme operating conditions.

[0091] The drive unit 100 is a linear drive unit; for example, the drive unit 100 can be a linear motor, an electric actuator, an electric cylinder, etc. Alternatively, please refer to... Figure 2 and Figure 3The driving component 100 is equipped with a transmission structure that converts the rotation of the motor output shaft into linear motion. Taking a lead screw structure as an example, the driving component 100 includes a motor 110 and a sleeve 120 connected to the output shaft of the motor 110. A shaft 130 is internally connected to the sleeve 120. When the motor 110 drives the sleeve 120 to rotate, the shaft 130 can extend or retract. Simultaneously, a gear ring 121 is fitted onto the outside of the sleeve 120. The adjusting component 400 has a meshing tooth 401 at one end near the driving component 100, and the gear ring 121 meshes with the meshing tooth 401 of the adjusting component 400. Therefore, when the adjusting component 400 is manually rotated, the sleeve 120 will rotate through the meshing tooth 401 and the gear ring 121, causing the shaft 130 to extend or retract, thus achieving manual adjustment.

[0092] Secondly, embodiments of this application provide a vehicle lamp, including a lamp housing, an illumination module 20 disposed within the lamp housing, and a dimming structure 10 as described in the first aspect. A driving member 100 is connected to the lamp housing, a dimming bracket 200 is fixedly connected to the illumination module 20, and a fulcrum 201 is connected to the lamp housing.

[0093] This configuration helps reduce the probability of interference or insufficient installation space in the drive component 100, thereby improving the reliability and stability of the dimming structure 10.

[0094] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
