Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a dimming component, a vehicle lighting system, and a vehicle. Background Technology

[0002] With the rapid development of the vehicle industry, the frequency of model upgrades and replacements has accelerated significantly, and the appearance has become increasingly diverse. In order to adapt to market competition and reduce costs, OEMs widely use the vehicle structure and sheet metal parts during the R&D iteration process. However, when upgrading a model or using a shared platform model, changes in the shape of the lights will lead to changes in the position of the dimming point. However, due to the safety requirements of the lights, the body sheet metal that should have been used may be forced to be modified because it cannot be adapted to the large old dimming system, which greatly increases the difficulty, cycle and cost of development.

[0003] Current multi-level dimming systems for automotive lights primarily employ structures such as worm gears, planetary gears, or long shaft drives. These structures are complex and bulky, increasing the overall dimensions of the dimming system and making it prone to interference with surrounding components, which is detrimental to the overall vehicle layout. Furthermore, because the dimming system transmits power through long screws or shafts, these shafts are susceptible to twisting, deformation, or even breakage due to uneven stress during dimming, potentially leading to dimming jamming or malfunction. Utility Model Content

[0004] This application provides a dimming component, a vehicle lighting system, and a vehicle that can change the direction of transmission in a confined space, which is beneficial to the overall vehicle layout.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

One side of the first transmission member is tractively connected to the adjusting part, the other side of the first transmission member is tractively connected to one side of the second transmission member, and the other side of the second transmission member is tractively connected to the adjusting rod. The rotational axis of the first transmission member is parallel to the axial direction of the adjusting rod, the rotational axis of the second transmission member is perpendicular to the rotational axis of the first transmission member, and the adjusting part is perpendicular to the rotational axis of the first transmission member.

When arranging the dimming assembly, the placement and rotation direction of the second transmission member, the first transmission member, and the adjusting part can be adjusted according to the shape and size of the space. This allows the positions of the first transmission member, the second transmission member, and the adjusting part to adapt to confined spaces, reducing the space occupied by the dimming assembly and minimizing interference between the dimming assembly and surrounding structures. This is beneficial for the overall vehicle layout, the reuse of the vehicle platform and sheet metal structure, and can also be applied to newly developed models.

[0017] In the above embodiments, the first connecting rod and the second connecting rod are connected separately, which can reduce the torsional deformation during the transmission process, thereby reducing the jamming caused by the deformation of the first transmission component during the transmission process.

[0041] Current multi-level dimming systems for automotive lights primarily employ structures such as worm gears, planetary gears, or long-shaft drives. These structures are complex and bulky, increasing the overall dimensions of the dimming system and making it prone to interference with surrounding components, which is detrimental to the overall vehicle layout. Furthermore, because the dimming system transmits power via long screws or shafts, these shafts are susceptible to twisting, deformation, or even breakage during the dimming process due to uneven stress. Long-distance screw or shaft drives typically involve significant frictional resistance and torque loss, causing the output torque of the final drive dimming system to often exceed the stringent standards of the original equipment manufacturer (OEM).

[0042] In addition, the current traditional dimming system has a complex structure, requires high skills from assembly workers, is cumbersome and difficult to operate, is not conducive to rapid assembly, has low production efficiency, and reduces overall production efficiency.

[0043] Firstly, reference Figures 1 to 3 This application provides a dimming assembly, which includes a housing 1, an adjusting slider 2, an adjusting rod 3, an adjusting part 4, and a transmission part 5. The housing 1 includes a bottom wall 11. The adjusting slider 2 is connected to a vehicle light assembly (not shown in the figure). The adjusting rod 3 is rotatably connected to the bottom wall 11. The adjusting rod 3 cooperates with the adjusting slider 2 to drive the adjusting slider 2 to move along the axial direction of the adjusting rod 3. The adjusting part 4 is rotatably disposed on the bottom wall 11. The transmission part 5 includes a first transmission member 51 and a second transmission member 52. Both the first transmission member 51 and the second transmission member 52 are rotatably connected to the bottom wall 11. One side of the first transmission member 51 is tractively connected to the adjusting part 4, and the other side of the first transmission member 51 is tractively connected to one side of the second transmission member 52. The other side of the second transmission member 52 is tractively connected to the adjusting rod 3. The rotation axis of the first transmission member 51 is parallel to the axis of the adjusting rod 3, and the rotation axis of the second transmission member 52 is perpendicular to the rotation axis of the first transmission member 51. The adjusting part 4 is perpendicular to the rotation axis of the first transmission member 51.

[0044] The dimming assembly proposed in this embodiment adopts a multi-stage transmission method. That is, the adjustment unit 4 transmits power to the first transmission member 51, the first transmission member 51 then transmits power to the second transmission member 52, and the second transmission member 52 transmits power to the adjustment rod 3. The adjustment rod 3 adjusts the light output direction of the vehicle lamp assembly. In other words, by rotating the adjustment unit 4, the first transmission member 51 is driven to rotate, the first transmission member 51 drives the second transmission member 52 to rotate, and the second transmission member 52 drives the adjustment rod 3 to rotate. The rotation of the adjustment rod 3 can drive the adjustment slider 2 to move along the axial direction of the adjustment rod 3, thereby achieving the purpose of adjusting the light of the vehicle lamp assembly.

[0045] The dimming assembly proposed in this application specifies that the rotation axis of the first transmission member 51 is parallel to the axis of the adjusting rod 3, the rotation axis of the second transmission member 52 is perpendicular to the rotation axis of the first transmission member 51, and the adjusting part 4 is perpendicular to the rotation axis of the first transmission member 51. When arranging the dimming assembly, the position and rotation direction of the second transmission member 52, the first transmission member 51, and the adjusting part 4 can be adjusted according to the shape and size of the space. This allows the positions of the first transmission member 51, the second transmission member 52, and the adjusting part 4 to adapt to confined spaces, reducing the space occupied by the dimming assembly and minimizing interference between the dimming assembly and surrounding structures. This is beneficial for the overall vehicle layout, the reuse of the vehicle platform and sheet metal structure, and can also be applied to newly developed models. In other words, the multi-stage transmission method used in this application allows for flexible arrangement of the positions of the first transmission member 51, the second transmission member 52, and the adjusting part 4 within a compact space.

[0046] In addition, the dimming assembly in this application adopts a multi-stage transmission method, which can improve the positioning accuracy and reliability of the adjustment part 4, the first transmission member 51, the second transmission member 52, and the adjustment rod 3, thereby improving the rigidity and stability of the adjustment part 4, the first transmission member 51, and the second transmission member 52 during the transmission process.

[0047] In this application, the transmission methods between the adjusting part 4 and the first transmission member 51, between the first transmission member 51 and the second transmission member 52, and between the second transmission member 52 and the adjusting rod 3 can be determined according to specific usage conditions. For example, the adjusting part 4 and the first transmission member 51 can be driven by gear meshing, the first transmission member 51 and the second transmission member 52 can be driven by gear meshing, and the second transmission member 52 and the adjusting rod 3 can be driven by gear meshing; or the adjusting part 4 and the first transmission member 51 can be driven by worm gear, the first transmission member 51 and the second transmission member 52 can be driven by gear meshing, and the second transmission member 52 and the adjusting rod 3 can be driven by gear meshing, etc., as long as the transmission between the adjusting part 4, the first transmission member 51, the second transmission member 52 and the adjusting rod 3 can be realized, and the setting positions of the adjusting part 4, the first transmission member 51 and the second transmission member 52 can be flexibly adjusted.

[0048] It should be noted that the dimming assembly in this application also includes a motor 20, which is connected to the adjustment slider 2 for electrically adjusting the light of the vehicle light assembly; while the adjustment part 4, the first transmission member 51, the second transmission member 52 and the adjustment rod 3 in this application are used for manually adjusting the light of the vehicle light assembly.

[0049] Optionally, refer to Figure 2 and Figure 3The adjusting part 4 has a first bevel gear 41. Along the rotation axis of the first transmission member 51, the two sides of the first transmission member 51 have a second bevel gear 511 and a third bevel gear 512 respectively. Along the rotation axis of the second transmission member 52, the two sides of the second transmission member 52 have a fourth bevel gear 521 and a fifth bevel gear 522 respectively. The first bevel gear 41 meshes with the second bevel gear 511, the third bevel gear 512 meshes with the fourth bevel gear 521, and the fifth bevel gear 522 meshes with the adjusting rod 3 gear.

[0050] For example, the adjusting rod 3 is provided with a sixth bevel gear 31, which meshes with the fifth bevel gear 522. Rotating the adjusting part 4 causes the first transmission member 51 to rotate via the meshing of the first bevel gear 41 and the second bevel gear 511. The first transmission member 51 then meshes with the fourth bevel gear 521 via the third bevel gear 512, causing the second transmission member 52 to rotate. The second transmission member 52 meshes with the sixth bevel gear 31 via the fifth bevel gear 522, causing the adjusting rod 3 to rotate. The rotation of the adjusting rod 3 drives the adjusting slider 2 to move axially along the adjusting rod 3, thereby achieving the purpose of adjusting the light of the vehicle headlight assembly.

[0051] The transmission between the adjustment unit 4, the first transmission component 51, the second transmission component 52, and the adjustment rod 3 all adopts bevel gear meshing, which enables flexible reversing in a small and compact space, reduces space occupancy, and minimizes interference with surrounding parts, thus benefiting the overall vehicle layout. Furthermore, the use of bevel gear meshing in each transmission stage improves the positioning accuracy between various structures, enhances the stability of torque output, and reduces the risk of torque loss and torsional deformation during transmission.

[0052] Optionally, refer to Figure 2 and Figure 3 The adjustment unit 4 also includes a first body part 42, a first bevel gear 41 is disposed at one end of the first body part 42 along its rotation axis, and a first rotating groove (not shown in the figure) is provided on the bottom wall 11. The first body part 42 is rotatably disposed in the first rotating groove. The dimming assembly also includes a first pressure plate 6, which covers the first body part 42 and is connected to the bottom wall 11 to limit the first body part 42 to the first rotating groove.

[0053] The first body part 42 is located within the first rotating groove and can rotate relative to the first rotating groove. The first bevel gear 41 is located at one end of the rotation axis of the first body part 42 and is located outside the first rotating groove. When the first body part 42 rotates, the first bevel gear 41 rotates synchronously, driving the second transmission member 52 to rotate. The first pressure plate 6 and the first rotating groove define the space for the first body part 42 to rotate. The first pressure plate 6 is detachably connected to the bottom wall 11. For example, the first pressure plate 6 has an arc-shaped portion and two ears. The two ears of the first pressure plate 6 are located on both sides of the arc-shaped portion of the first pressure plate 6. The arc-shaped portion of the first pressure plate 6 covers the first body part 42 to define the space for the first body part 42 to rotate with the first rotating groove. The two ears of the first pressure plate 6 are detachably connected to the bottom wall 11. For example, the two ears of the first pressure plate 6 are connected to the bottom wall 11 by a first screw.

[0054] When the first body part 42 rotates in the first rotating groove, the first pressure plate 6 limits the first body part 42, thereby reducing the movement of the first body part 42 during the transmission process and improving the stability of the dimming assembly during the transmission process.

[0055] Optionally, the housing 1 also includes a side wall 12 surrounding the bottom wall 11, the side wall 12 having a first through hole 120, the side of the first body part 42 away from the first bevel gear 41 extending into the first through hole 120, and a sealing member 10 being provided between the first body part 42 and the hole wall of the first through hole 120.

[0056] The first body portion 42 extends into the first through hole 120 from the side away from the first bevel gear 41, allowing for manual rotation of the first body portion 42. The end of the first body portion 42 away from the first bevel gear 41 can be located within or extend beyond the first through hole 120, as long as it can be manually rotated. The end of the first body portion 42 away from the first bevel gear 41 has a countersunk hole with a hexagonal cross-section to facilitate manual rotation.

[0057] A sealing element 10 is provided between the first body part 42 and the hole wall of the first through hole 120. The inner ring of the sealing element 10 abuts against the first body part 42, and the outer ring of the sealing element 10 abuts against the hole wall of the first through hole 120, so as to achieve a seal between the first body part 42 and the hole wall of the first through hole 120 and reduce light leakage.

[0058] Optionally, refer to Figure 2 and Figure 3The second transmission component 52 also includes a second body part 520, a fourth bevel gear 521 and a fifth bevel gear 522 respectively disposed on both sides of the second body part 520 along its rotation axis, and a second rotation groove (not shown in the figure) provided on the bottom wall 11, the second body part 520 being rotatably disposed in the second rotation groove; the dimming assembly also includes a second pressure plate 7, the second pressure plate 7 being disposed on the second body part 520 and connected to the bottom wall 11, so as to limit the second body part 520 to be located in the second rotation groove.

[0059] The second body portion 520 is disposed within the second rotating groove and can rotate within the second rotating groove. The fourth bevel gear 521 and the fifth bevel gear 522 are respectively disposed on both sides of the second body portion 520 along the rotation axis of the second body portion 520. When the fourth bevel gear 521 rotates under the drive of the third bevel gear 512, it synchronously drives the second body portion 520 and the fifth bevel gear 522 to rotate. The second pressure plate 7 and the second rotating groove define the space for the second body portion 520 to rotate. The second pressure plate 7 is detachably connected to the bottom wall 11. For example, the second pressure plate 7 has an arc-shaped portion and two ears. The two ears of the second pressure plate 7 are located on both sides of the arc-shaped portion of the second pressure plate 7. The arc-shaped portion of the second pressure plate 7 covers the second body portion 520 to define the space for the second body portion 520 to rotate with the second rotating groove. The two ears of the second pressure plate 7 are detachably connected to the bottom wall 11. For example, the two ears of the second pressure plate 7 are connected to the bottom wall 11 by a second screw.

[0060] When the second body part 520 rotates in the second rotating groove, the second pressure plate 7 limits the second body part 520, thereby reducing the movement of the second body part 520 during the transmission process and improving the stability of the dimming assembly during the transmission process.

[0061] Optionally, refer to Figure 1 The bottom wall 11 includes a main body 111 and a protrusion 112. Along the axial direction of the adjusting rod 3, the protrusion 112 protrudes from the main body 111. The adjusting part 4 is disposed on the protrusion 112. The second transmission member 52 is disposed on the main body 111. The first transmission member 51 also includes a first connecting rod 513 and a second connecting rod 514. One side of the first connecting rod 513 is connected to the second bevel gear 511, and one side of the second connecting rod 514 is connected to the third bevel gear 512. The other side of the first connecting rod 513 and the other side of the second connecting rod 514 are engaged.

[0062] Along the axial direction of the adjusting rod 3, the protrusion 112 protrudes from the main body 111. That is to say, there is a height difference between the setting position of the adjusting part 4 and the second transmission member 52. The adjusting part 4 realizes the transmission connection and the change of transmission direction through the first transmission member 51 set in the axial direction parallel to the adjusting rod 3.

[0063] The first transmission component 51 includes a first connecting rod 513 and a second connecting rod 514. The first transmission component 51 adopts a split design, that is, the first connecting rod 513 and the second connecting rod 514 adopt a short shaft design, which can reduce the torsional deformation during the transmission process, thereby reducing the jamming caused by the deformation of the first transmission component 51 during the transmission process.

[0064] Furthermore, the first connecting rod 513 and the second connecting rod 514 are engaged by a snap-fit ​​mechanism, which simplifies the installation process and improves assembly efficiency. For example, the connection between the first connecting rod 513 and the second connecting rod 514 can be any possible method, such as a keyway, as long as it allows for a detachable snap-fit ​​between the two rods and ensures that the rotation of the first connecting rod 513 can drive the rotation of the second connecting rod 514.

[0065] Optionally, refer to Figures 1 to 3 The dimming assembly also includes a bracket 8, which is connected to the protrusion 112. Along the rotation axis of the first transmission member 51, the bracket 8 has a through second hole 80. The other side of the first connecting rod 513 and the other end of the second connecting rod 514 are located in the second through hole 80.

[0066] The bracket 8 is fixedly connected to the protrusion 112 by fasteners. For example, the bracket 8 is connected by three fasteners, two of which are first screws. One end of the first connecting rod 513 is provided with a second bevel gear 511 that meshes with the first bevel gear 41. The other end of the first connecting rod 513 is located in the second through hole 80 and can rotate within the second through hole 80. The second through hole of the bracket 8 can position the rotation of the first connecting rod 513. One end of the second connecting rod 514 is sleeved on the protrusion of the bottom wall 11, and this end of the second connecting rod 514 is provided with a third bevel gear 512. The other end of the second connecting rod 514 is located in the second through hole 80. The bracket 8 can position the rotation of the second connecting rod 514. That is to say, the bracket 8 improves the positioning accuracy of the first transmission component 51, thereby making the transmission of the first transmission component 51 more stable.

[0067] Optionally, refer to Figure 2 and Figure 3 The adjusting slider 2 is provided with a mating groove 21, and the adjusting rod 3 is threadedly engaged with the mating groove 21; the dimming assembly also includes a locking buckle 9, which is connected to the adjusting slider 2 and is used to limit the adjusting rod 3 to the mating groove 21.

[0068] The adjusting rod 3 is accommodated in the mating groove 21. When the adjusting rod 3 rotates, the adjusting slider 2 is driven to move linearly along the axial direction of the adjusting rod 3 through the threaded engagement between the adjusting rod 3 and the mating groove 21, thereby achieving the purpose of dimming the vehicle headlight assembly. The latch 9 and the mating groove 21 define the space for the adjustment rod 3 to rotate. The latch 9 and the adjusting slider 2 are detachably connected. For example, the latch 9 has an arc-shaped portion and two ears. The two ears of the latch 9 are located on both sides of the arc-shaped portion of the latch 9. The arc-shaped portion of the latch 9 surrounds the adjusting rod 3 to define the space for the adjustment rod 3 to rotate with the mating groove 21. The two ears of the latch 9 are detachably connected to the adjusting slider 2.
