Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, specifically relating to a dimming component, a lamp, and an automobile. Background Technology

[0002] In automotive lighting, dimming components are used to adjust the beam angle of the lights, providing the driver with better visibility.

[0003] In related technologies, during the assembly process of dimming components, the ball head and dimming bracket of the dimming component are prone to misalignment, causing damage to the ball head, resulting in a low yield of dimming components and affecting the assembly efficiency of lamps. Summary of the Invention

[0004] Based on the above-mentioned technical problems, this application provides a dimming component, a lamp, and an automobile, aiming to at least partially solve the problem that the ball joint and dimming bracket of the dimming component are prone to misalignment, causing damage to the ball joint, so as to ensure the yield rate of the dimming component and improve the assembly efficiency of the lamp.

[0005] In a first aspect of this application, a dimming assembly is provided, the dimming assembly comprising: a dimming bracket including a snap-fit ​​portion, the snap-fit ​​portion having a snap-fit ​​groove and a snap-fit ​​hole, the snap-fit ​​hole being formed at the bottom of the snap-fit ​​groove; and a ball joint seat including a snap-fit ​​member and a base body. ， An inwardly recessed limiting groove is formed between the snap-fit ​​member and the base body; wherein, the snap-fit ​​member passes through the snap-fit ​​hole and is located outside the snap-fit ​​groove, at least a portion of the base body is located within the snap-fit ​​groove, and a portion of the snap-fit ​​part is fitted into the limiting groove to limit the relative position of the ball head base and the dimming bracket.

[0006] The dimming assembly provided in this application allows for the control of at least one of the dimming bracket and ball head seat during assembly, bringing them closer together. The ball head seat's locking member passes through the locking hole via the opening side of the locking groove, positioning itself outside the groove. The locking part moves into the limiting groove, thereby restricting the position of the dimming bracket through the limiting groove of the ball head seat. This allows the dimming bracket to automatically correct its alignment, ensuring coaxiality between the dimming bracket and the ball head seat, and consequently, ensuring balanced force on the ball head seat. This prevents damage caused by uneven force on the ball head seat, ensuring a high yield rate for the dimming assembly and correspondingly improving the assembly efficiency of the lighting fixture.

[0007] In some implementations, the snap-fit ​​portion includes a plurality of first spring tabs, which are circumferentially spaced around the snap-fit ​​hole. One end of the plurality of first spring tabs is connected to a connecting sleeve, and the other end of the plurality of first spring tabs is suspended and extends toward each other. The other end of the plurality of first spring tabs forms the snap-fit ​​hole, and the other end of the plurality of first spring tabs is fitted into the limiting groove. Two adjacent first spring tabs form a first channel.

[0008] In some implementations, the first spring and the snap-fit ​​element are in planar contact.

[0009] In some embodiments, the first spring includes a support section, at least a portion of which is fitted into the limiting groove, and the side of the support section that is in contact with the snap-fit ​​member is a plane.

[0010] In some embodiments, the ball head seat further includes a limiting part connected to the periphery of the seat body, the limiting part and the snap-fit ​​member being located on both sides of the dimming bracket, and the dimming bracket and the limiting part abutting against each other.

[0011] In some implementations, one of the limiting part and the dimming bracket is provided with a plurality of limiting ribs, and the other abuts against the plurality of limiting ribs.

[0012] In some embodiments, the snap-fit ​​portion and the bottom of the limiting groove are spaced apart.

[0013] In some embodiments, the snap-fit ​​element has a chamfered edge at at least one end along the opening direction of the snap-fit ​​hole.

[0014] In a second aspect of this application, a lighting fixture is provided, the lighting fixture including the dimming component described in the first aspect.

[0015] In a third aspect, this application also provides an automobile that includes the aforementioned lamps.

[0016] The luminaire with the dimming component described in the first aspect and the automobile with the luminaire can avoid damage to the ball joint when assembling the dimming bracket and the ball joint, thereby ensuring the yield rate of the dimming component and improving the assembly efficiency of the luminaire.

[0042] The technical solutions in this application will now be clearly and thoroughly described with reference to the accompanying drawings. Specifically, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0043] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] Today, cars are the most important means of transportation for every household. Their widespread use has enriched human life and accelerated its pace. Car lights provide illumination, lighting the way forward and ensuring driving safety. The high and low beams of car lights, as the most basic lighting function, can be adjusted via related dimming components to change the angle of the beam in all directions, providing the driver with a better field of vision.

[0045] Figure 1 A schematic diagram of the structure of a dimming component 10' in the related art is shown. Combined with... Figure 1 The dimming assembly 10' in the related technology includes a dimming bracket 110', a ball head seat 120', and a ball head screw 130'. The lamp body is mounted on the dimming bracket 110', and the ball head screw 130' is mounted on the lamp housing 20. The dimming bracket 110' and the ball head screw 130' are connected by the ball head seat 120'. The dimming bracket 110' has an assembly channel 111', and the inner wall of the assembly channel 111' is connected to a support protrusion 112'. The assembly end of the ball head screw 130 is movably mounted in the ball head seat 120. The ball head seat 120 is inserted into the assembly channel 111' with a gap. The support protrusion 112' abuts against the outer surface of the ball head seat 120' so that the dimming bracket 110' can rotate relative to the ball head seat 120'. Driven by the power component, the position of the dimming bracket 110' relative to the ball screw 130' can be changed, thereby adjusting the position of the lamp body relative to the lamp housing 20 and changing the angle of the lamp beam.

[0046] During assembly Figure 1 When using the dimming assembly 10' shown, the ball head 120' is typically installed on the ball head screw 130' first, and then pressure is applied to the dimming bracket 110' so that the support protrusion 112' can abut against the ball head 120'. However, because the assembly end of the ball head screw 130' is movably fitted into the ball head 120' when the dimming bracket 110' is pressed down, the ball head 120' may deviate from the ball head screw 130' under the driving pressure of the dimming bracket 110' (e.g., Figure 2 As shown, if the angle between the ball head seat 120' and the ball head screw 130' is too large, the force on the ball head seat 120' will be uneven, and the downward pressing of the dimming bracket 110' will easily damage the ball head seat 120', resulting in a low yield of the dimming assembly 10', which in turn affects the assembly efficiency of the lamp.

[0047] Based on the above-mentioned technical problems, this application provides a dimming component 10, a lamp, and an automobile, which aims to at least partially solve the problem that the ball head 120 and the dimming bracket 110 of the dimming component 10 are prone to misalignment, causing damage to the ball head 120, so as to ensure the yield rate of the dimming component 10 and improve the assembly efficiency of the lamp.

[0048] In a first aspect, this application provides a dimming component 10. Figure 3 A schematic diagram of the structure of a dimming assembly 10 according to one or more embodiments of this application is shown. Figure 4 It shows Figure 3 An explosion diagram. Figure 5 It shows Figure 3 A top-down view diagram. Figure 6 It shows Figure 5 A schematic diagram of the AA cross-section. Combined with... Figures 3-6 The dimming assembly 10 includes a dimming bracket 110 and a ball head seat 120. The dimming bracket 110 includes a snap-fit ​​portion 111, which is provided with a snap-fit ​​groove 1111 and a snap-fit ​​hole 1112. The snap-fit ​​hole 1112 is formed at the bottom of the snap-fit ​​groove 1111. The ball head seat 120 includes a snap-fit ​​member 121 and a seat body 123. An inwardly recessed limiting groove 122 is formed between the snap-fit ​​member 121 and the seat body 123. The snap-fit ​​member 121 passes through the snap-fit ​​hole 1112 and is located outside the snap-fit ​​groove 1111. At least a portion of the seat body 123 is located inside the snap-fit ​​groove 1111. A portion of the snap-fit ​​portion 111 is fitted into the limiting groove 122 to limit the relative position of the ball head seat 120 and the dimming bracket 110.

[0049] The dimming assembly 10 provided in this application can control the movement of at least one of the dimming bracket 110 and the ball head seat 120 during assembly, so that the dimming bracket 110 and the ball head seat 120 are close together. The snap-fit ​​part 121 of the ball head seat 120 passes through the snap-fit ​​hole 1112 through the opening side of the snap-fit ​​groove 1111, so that the snap-fit ​​part 121 is located outside the snap-fit ​​groove 1111. The snap-fit ​​part 111 is assembled and moved into the limiting groove 122, so that the position of the dimming bracket 110 can be limited by the limiting groove 122 of the ball head seat 120, so that the dimming bracket 110 can automatically correct itself, thereby ensuring the coaxiality of the dimming bracket 110 and the ball head seat 120, and thus ensuring the balanced force on the ball head seat 120, avoiding damage caused by uneven force on the ball head seat 120, thereby ensuring the yield rate of the dimming assembly 10 and improving the assembly efficiency of the lamp accordingly.

[0050] Figure 7 It shows Figure 3 A frontal view diagram. Combined with... Figure 7 For ease of description, we now define Figure 7The orientation shown is vertical, meaning the dimming bracket 110 is above the ball joint 120, and the ball screw 130 (described below) is below the ball joint 120. When assembling the dimming bracket 110 and the ball joint 120, the snap-fit ​​member 121 of the ball joint 120 passes through the opening side of the snap-fit ​​groove 1111 from bottom to top through the snap-fit ​​hole 1112, so that the snap-fit ​​member 121 is positioned with its top surface above the snap-fit ​​member 111. The snap-fit ​​portion 111 moves into the limiting groove 122 to limit the relative position of the ball joint 120 and the dimming bracket 110. The specific details of the dimming assembly 10 will now be further described with reference to the accompanying drawings.

[0051] Figure 8 A schematic diagram of the dimming bracket 110 is shown. Figure 9 It shows Figure 8 A structural diagram from another perspective. Combined with... Figure 8 as well as Figure 9 The dimming bracket 110 includes a connecting sleeve 113 and a plurality of connecting rods 114. The connecting sleeve 113 extends axially and forms a first assembly cavity 1131 for assembling the ball head seat 120. One end of the plurality of connecting rods 114 is connected to the periphery of the connecting sleeve 113, and the other end of the plurality of connecting rods 114 extends radially outward from the connecting sleeve 113 to form a carrier for mounting the lamp. In one embodiment, the connecting rods 114 are arranged radially along the connecting sleeve 113, that is, the connecting rods 114 extend horizontally. In other embodiments, the connecting rods 114 may also be inclined radially to the connecting sleeve 113. The specific design can be tailored according to the structural shape of the lamp body and the lamp housing 20, and this application does not impose any limitations on this.

[0052] Combination Figure 8 as well as Figure 9 In one embodiment, two connecting rods 114 are provided, and the two connecting rods 114 are arranged perpendicularly to each other. In other embodiments, more connecting rods 114 may be provided, such as three, four, five, etc., which can be set according to the shape of the lamp body and the internal space of the lamp housing 20. This application does not impose any restrictions here.

[0053] Combination Figure 8 as well as Figure 9The outer edge of the snap-fit ​​part 111 is connected to the connecting sleeve 113. The middle part of the snap-fit ​​part 111 extends towards the top of the connecting sleeve 113 so that the snap-fit ​​part 111 forms an upwardly concave snap-fit ​​groove 1111. The opening side of the snap-fit ​​groove 1111 faces downward, that is, the opening side of the snap-fit ​​groove 1111 faces downward towards the ball head seat 120. The snap-fit ​​part 111 has the aforementioned snap-fit ​​hole 1112 in the middle part. The snap-fit ​​hole 1112 can be circular and coaxial with the connecting sleeve 113. When the snap-fit ​​member 121 of the ball head seat 120 passes through the snap-fit ​​hole 1112 through the opening side of the snap-fit ​​groove 1111, the end of the snap-fit ​​member 111 facing the snap-fit ​​hole 1112 moves into the limiting groove 122.

[0054] Combination Figure 8 as well as Figure 9 In order to allow the snap-fit ​​member 121 of the ball joint 120 to pass smoothly through the snap-fit ​​hole 1112, the snap-fit ​​groove member 111 of this application has a plurality of first channels 1113. One end of the plurality of first channels 1113 is connected to the snap-fit ​​hole 1112, and the other end of the plurality of first channels 1113 extends toward the edge of the snap-fit ​​groove 1111. That is, the arrangement of the plurality of first channels 1113 can divide the snap-fit ​​member into a plurality of first spring pieces 1114. In other words, the snap-fit ​​member 111 includes a plurality of circumferentially spaced pieces around the snap-fit ​​hole 1112. The first spring piece 1114 is arranged, one end of the first spring piece 1114 is connected to the axial bottom end of the connecting sleeve 113, and the other end of the first spring piece 1114 is suspended and extends in a direction that approaches each other, that is, extends towards the axial top end of the connecting sleeve 113. The other end of the first spring piece 1114 forms the above-mentioned snap-fit ​​hole 1112, and two adjacent first spring pieces 1114 form the above-mentioned first channel 1113, thereby making the snap-fit ​​part 111 that forms the snap-fit ​​groove 1111 have a certain elasticity. When the dimming bracket 110 and the ball head seat 120 move relative to each other, the locking member 121 of the ball head seat 120 can push open multiple first spring pieces 1114, causing one end of each first spring piece 1114 to elastically deform upwards. This increases the opening size of the locking hole 1112 to the maximum cross-sectional area of ​​the locking member 121 of the ball head seat 120, allowing the locking member 121 of the ball head seat 120 to pass smoothly through the locking hole 1112. The locking member 121 of the ball head seat 120 is positioned above the locking hole 1112. After the locking member 121 of the ball head seat 120 is positioned above the locking hole 1112, the multiple first spring pieces 1114 automatically return to their original positions and move into the limiting groove 122 on the periphery of the ball head seat 120 to limit the relative position of the dimming bracket 110 and the ball head seat 120.

[0055] Combination Figure 8 as well as Figure 9In some embodiments, the top end of the connecting sleeve 113 can be open, and the bottom end of the connecting sleeve 113 is connected to a flange 115 extending into the connecting sleeve 113. The flange 115 can extend radially along the connecting sleeve 113 so that the flange 115 is in a horizontal position. In addition, the flange 115 is annular so that the bottom end of the connecting sleeve 113 forms a through hole 1151. The through hole 1151 and the connecting sleeve 113 are coaxially arranged. The through hole 1151 is the opening side of the snap-fit ​​groove 1111. The area of ​​the through hole 1151 is larger than the maximum cross-sectional area of ​​the snap-fit ​​member 121 of the ball head seat 120 so that the snap-fit ​​member 121 of the ball head seat 120 can pass through the through hole 1151 and enter the snap-fit ​​groove 1111.

[0056] Combination Figure 8 as well as Figure 9 One end of each of the multiple first springs 1114 is connected to the inner side of the flange 115. The multiple first springs 1114 can be integrally formed with the flange 115, the connecting sleeve 113, and the connecting rod 114, that is, the dimming bracket 110 is an integrally formed structure, so as to facilitate the production and assembly of the dimming bracket 110.

[0057] Combination Figure 8 as well as Figure 9 Multiple first spring pieces 1114 can be arranged at equal intervals around the snap-fit ​​hole 1112 so that multiple first channels 1113 are arranged at equal intervals around the snap-fit ​​hole 1112. When the snap-fit ​​member 121 of the ball head seat 120 pushes open the multiple first spring pieces 1114, the force on the multiple first spring pieces 1114 is balanced, and the deformation of the multiple first spring pieces 1114 is consistent or nearly consistent. After the snap-fit ​​member 121 of the ball head seat 120 passes through the snap-fit ​​hole 1112, the multiple first spring pieces 1114 can return to their original position smoothly and apply the same or nearly the same force to the ball head seat 120, ensuring the coaxiality of the dimming bracket 110 and the ball head seat 120.

[0058] Figure 10 It shows Figure 8 A cross-sectional schematic diagram, combined with Figure 10The first spring piece 1114 includes a connecting section 11141, a transition section 11142, and a support section 11143. The connecting section 11141, the transition section 11142, and the support section 11143 are connected sequentially from the bottom end to the top end of the first spring piece 1114. The connecting section 11141, the transition section 11142, and the support section 11143 of the multiple first spring pieces 1114 all form a ring structure. The support section 11143 is connected to the inner side of the flange 115. The annular structure formed by the support sections 11143 of the multiple first spring pieces 1114 can be cylindrical or frustum-shaped. Furthermore, the inner diameter of the connecting section 11141 is larger than the maximum outer diameter of the snap-fit ​​member 121 of the ball head seat 120, allowing the snap-fit ​​member 121 of the ball head seat 120 to pass through the annular structure formed by the multiple connecting sections 11141 with a gap. The transition section 11142 of the multiple first spring pieces 1114 can be frustum-shaped. The inner diameter of the transition section 11142 decreases sequentially from the connecting section 11141 to the support section 11143. The minimum inner diameter of the transition section 11142 is also larger than the maximum outer diameter of the snap-fit ​​member 121 of the ball head seat 120, allowing the snap-fit ​​member 121 of the ball head seat 120 to pass through the annular space formed by the multiple connecting sections 11141 with a gap. 11143 can be an annular plate structure. The snap-fit ​​hole 1112 is opened in the middle of the support section 11143. The diameter of the support section 11143 is larger than the maximum outer diameter of the snap-fit ​​member 121 of the ball head seat 120. The inner diameter of the snap-fit ​​hole 1112 is smaller than the maximum outer diameter of the snap-fit ​​member 121 of the ball head seat 120 and larger than the inner diameter of the annular limiting groove 122, so that the snap-fit ​​member 121 of the ball head seat 120 can pass through the snap-fit ​​hole 1112 with interference fit. At the same time, at least a part of the support section 11143 is moved and assembled into the limiting groove 122. Since the support section 11143 is an annular plate structure, the side wall plane of the support section 11143 and the limiting groove 122 can be in contact. That is, the side of the support section 11143 and the snap-fit ​​member 121 that are in low contact is a plane, so that the first spring piece 1114 and the snap-fit ​​member 121 of the ball head seat 120 are in contact with the plane. This configuration increases the contact area between the first spring 1114 and the snap-fit ​​121 of the ball head seat 120, further ensuring the coaxiality of the dimming bracket 110 and the ball head seat 120, and ensuring the balanced force on the ball head seat 120, thus preventing damage to the ball head seat 120.

[0059] It should be noted that the phrase "at least part of the support section 11143 is moved and assembled into the limiting groove 122" means that the entire support section 11143 can be moved and assembled into the limiting groove 122, or that only a part of the inner side of the support section 11143 is moved and assembled into the limiting groove 122. This application does not impose any restrictions on this.

[0060] Figure 11 A schematic diagram of the ball joint 120 is shown. Figure 12 It shows Figure 11 A frontal view diagram. Combined with... Figure 11 as well as Figure 12 The ball joint 120 also includes a support member 124. The seat body 123, the support member 124 and the snap-fit ​​member 121 are connected in sequence along the axial direction of the ball joint 120 (from bottom to top in the figure). The outer diameter of the support member 124 is smaller than the outer diameter of the seat body 123 and the snap-fit ​​member 121, so that the seat body 123, the support member 124 and the snap-fit ​​member 121 can form the aforementioned recessed limiting groove 122, that is, the limiting groove 122 is in close contact with the snap-fit ​​member 121. When assembling the dimming bracket 110 and the ball head seat 120, the snap-fit ​​member 121 passes through the snap-fit ​​hole 1112 through the opening side of the snap-fit ​​groove 1111, so that the snap-fit ​​member 121 is located on the outside of the bottom of the snap-fit ​​groove 1111 (on the top surface side of the snap-fit ​​part 111), and the end of the snap-fit ​​part 111 moves into the limiting groove 122 towards the snap-fit ​​hole 1112 to limit the relative position of the ball head seat 120 and the dimming bracket 110.

[0061] Combination Figure 11 as well as Figure 12 The snap-fit ​​component 121 has a plate-like structure. The top edge of the snap-fit ​​component 121 (that is, the axial top edge of the snap-fit ​​component 121) is provided with a first chamfer 1211. During the process of the snap-fit ​​component 121 passing through the snap-fit ​​hole 1112, the top of the snap-fit ​​component 121 acts on the top edge of the first spring piece 1114 (support section 11143). The top edge of the first spring piece 1114 can move along the first chamfer 1211 so that the snap-fit ​​component 121 of the ball head seat 120 can pass smoothly through the snap-fit ​​hole 1112.

[0062] Combination Figure 11 as well as Figure 12 The bottom edge of the snap-fit ​​121 (i.e., the axial bottom end of the snap-fit ​​121) is provided with a second chamfer 1212. After the snap-fit ​​121 passes through the snap-fit ​​hole 1112, the top end of the first spring piece 1114 (support section 11143) can move along the second chamfer 1212 and smoothly enter the limiting groove 122 to improve the smoothness of the assembly of the ball head seat 120 and the dimming bracket 110.

[0063] Specifically, the angle of the first chamfer 1211 is smaller than the angle of the second chamfer 1212. The angle of the first chamfer 1211 can be 30°-60°, for example, the angle of the first chamfer 1211 is 45°. The angle of the second chamfer 1212 can be 30-40°, for example, the angle of the second chamfer 1212 is 35°. The specific angle can be set according to the specifications of the snap-fit ​​121 and the first spring 1114, which will not be elaborated here.

[0064] It should be noted that the edge of the snap-fit ​​member 121 may be provided with the first chamfer 1211 and the second chamfer 1212 at the same time, or it may be provided with only one of the first chamfer 1211 and the second chamfer 1212. That is, the snap-fit ​​member 121 has a chamfer on at least one end of its edge along the opening direction of the snap-fit ​​hole 1112.

[0065] Figure 13 A cross-sectional schematic diagram of the assembly of the dimming bracket 110 and the ball head seat 120 is shown. Combined with... Figures 11-13 The support member 124 is a rod-shaped structure, which is coaxially disposed between the base 123 and the snap-fit ​​member 121. The outer diameter of the support member 124 is slightly smaller than the inner diameter of the snap-fit ​​hole 1112. When the snap-fit ​​121 passes through the snap-fit ​​hole 1112 of the snap-fit ​​groove 1111 and is located outside the snap-fit ​​groove 1111, the top end (support section 11143) of the first spring piece 1114 moves into the limiting groove 122. The top end (support section 11143) of the first spring piece 1114 can have a certain distance from the support member 124. The first spring piece 1114 is movably disposed outside the support member 124, that is, there is a distance between the snap-fit ​​part 111 and the bottom of the limiting groove 122. The snap-fit ​​part 111 is movably disposed in the limiting groove 122. With this arrangement, the dimming bracket 110 can rotate smoothly relative to the support member 124 under the action of external force, so as to adjust the position angle of the dimming bracket 110 relative to the ball head seat 120, and then adjust the position of the lamp body relative to the lamp housing 20, thereby changing the angle of the lamp body beam.

[0066] Combination Figures 11-13 The ball head seat 120 also includes a limiting part 125, which is connected to the periphery of the seat body 123. A limiting groove 122 is disposed between the locking member 121 and the limiting part 125. The limiting part 125 and the locking member 121 are respectively located on both sides of the dimming bracket 110, and the dimming bracket 110 and the limiting part 125 abut against each other to further limit the position of the dimming bracket 110 through the limiting part 125. The limiting part 125 and the locking member 121 cooperate with each other to axially position the dimming bracket 110. In addition, the limiting part 125 can support the dimming bracket 110, increase the contact area between the dimming bracket 110 and the ball head seat 120, and improve the phenomenon of the ball head seat 120 being crushed by the dimming bracket 110.

[0067] Combination Figures 11-13In specific implementation, the base 123 can be bell-shaped. When the ball head seat 120 is assembled to the dimming bracket 110, the base 123 is fitted into the snap-fit ​​groove 1111. The base 123 forms a second assembly cavity 1231 for assembling the ball head screw 130. The base 123 includes a plurality of second spring pieces 1232. The first ends of the plurality of second spring pieces 1232 are connected to the bottom of the support member 124. The second ends of the plurality of second spring pieces 1232 are spaced apart around the support member 124 and extend radially downward. The second ends of the plurality of second spring pieces 1232 protrude from the snap-fit ​​groove 1111 and are located at the bottom of the dimming bracket 110. The limiting part 125 also includes a plurality of single-unit structures 1211. The single-unit structure 1211 and the first Two springs 1232 are arranged in a one-to-one correspondence. The single-unit structure 1211 is connected to the second end of the second spring 1232 and extends radially towards the outside of the second assembly cavity 1231 along the base 123, so that the single-unit structure 1211 is located at the bottom of the dimming bracket 110. Adjacent single-unit structures 1211 also have a gap. The flange 115 provided at the bottom of the connecting sleeve 113 supports multiple single-unit structures 1211, so that the connecting sleeve 113 abuts against the limiting part 125, and then the dimming bracket 110 abuts against the limiting part 125. This restricts the position of the dimming bracket 110 while increasing the contact area between the dimming bracket 110 and the ball head seat 120, and improves the phenomenon of the ball head seat 120 being crushed by the dimming bracket 110.

[0068] In this application, one of the limiting part 125 and the dimming bracket 110 is provided with multiple limiting ribs 126, and the other abuts against the multiple limiting ribs 126. This arrangement can ensure that the limiting part 125 supports and limits the connecting sleeve 113 while reducing the contact area between the limiting part 125 and the connecting sleeve 113. When the dimming bracket 110 can rotate relative to the support member 124 under the action of external force, the friction between the limiting part 125 and the connecting sleeve 113 can be reduced, allowing the dimming bracket 110 to rotate smoothly relative to the ball head seat 120.

[0069] Combination Figures 11-13 In some embodiments, each individual structure 1211 of the limiting part 125 is provided with a limiting rib 126 on its top. The limiting rib 126 can be arranged radially along the base 123. The flange 115 of the connecting sleeve 113 abuts against the limiting ribs 126 of the multiple individual structures 1211 to achieve the supporting and limiting function of the limiting part 125 on the connecting sleeve 113. In addition, the top of the limiting rib 126 is arc-shaped so that the connecting sleeve 113 and the limiting rib 126 are in line contact, further reducing the friction between the limiting part 125 and the connecting sleeve 113. In other embodiments, the bottom of the flange 115 of the connecting sleeve 113 is provided with multiple limiting ribs 126. The limiting ribs 126 are arranged one-to-one with the individual structures 1211. The limiting ribs 126 abut against the corresponding individual structures 1211, which can also achieve the supporting and limiting function of the limiting part 125 on the connecting sleeve 113.

[0070] Combination Figures 11-13 In this application, since the second ends of the multiple second springs 1232 of the seat 123 are arranged circumferentially around the support member 124, and the single structure 1211 is connected to the second ends of the second springs 1232, the second springs 1232 and the corresponding single structure 1211 divide the side wall of the seat 123 into multiple second channels 1233, so that the side wall of the seat 123 is elastic, so as to facilitate the assembly of the ball head screw 130 in the seat 123.

[0071] It should be noted that the base 123, support 124 and snap-fit ​​121 constituting the ball head seat 120 in this application are also integrally formed structures, that is, the ball head seat 120 is integrally formed, which facilitates the production and manufacturing of the ball head seat 120.

[0072] Figure 14 A schematic diagram of the ball-end screw 130 is shown. Figure 15 A schematic cross-sectional view of the assembly of the ball joint seat 120 and the ball screw 130 is shown. Figure 14 as well as Figure 15 The ball head screw 130 has a ball head end 131 and a screw end 132. The ball head end 131 is spherical and is rotatably fitted into the base 123. The screw end 132 is threaded to the lamp housing 20. When the dimming bracket 110 rotates relative to the ball head base 120 under the action of external force, the friction generated by the dimming bracket 110 and the ball head base 120 can also drive the ball head base 120 to rotate relative to the ball head screw 130, so as to adjust the position of the dimming bracket 110 relative to the ball head screw 130, thereby adjusting the position of the lamp body relative to the lamp housing 20 and changing the angle of the lamp beam.

[0073] In a second aspect, this application also provides a lighting fixture, which includes a dimming assembly 10 as described in the first aspect. The dimming assembly 10 is disposed between the lamp body and the lamp housing 20 of the lighting fixture. Driven by a power component, it can change the position of the dimming bracket 110 relative to the ball screw 130, thereby adjusting the position of the lamp body relative to the lamp housing 20 to change the angle of the lamp beam.

[0074] In a third aspect, this application also provides an automobile that includes the aforementioned lamp. When applied to the automotive field, the lamp can be a high beam headlight, low beam headlight, or high beam headlight.

[0075] The luminaire with the dimming component 10 and the automobile with the luminaire can avoid damage to the ball joint 120 when assembling the dimming component 10, thereby ensuring the yield of the dimming component 10, improving the assembly efficiency of the luminaire, and having good practicality.
