Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle lighting assembly and a vehicle using the vehicle lighting assembly. Background Technology

[0002] Headlights are the core component of a vehicle's lighting system, using internal optical components to precisely control the beam to meet driving safety requirements. The reflector, a key optical element of the headlight, uses a specific curved surface design to reflect the light emitted by the light source and form a light pattern distribution that meets regulatory requirements. The opening angle of the reflector directly affects the focusing and diverging characteristics of the light pattern.

[0003] In related technologies, the driving structure of the reflector bowl typically employs a motor-driven gear transmission system. Specifically, the motor's output shaft is connected to a drive gear, which meshes with a ring gear. The inner ring of the ring gear has a toothed structure that engages with the meshing teeth at the top of the rotating shaft, while the meshing teeth at the bottom of the rotating shaft connect to a horizontal rack, which is connected to the reflector bowl via a transmission connection. When the motor is running, power is transmitted sequentially through the gear, ring gear, rotating shaft, and rack, driving the reflector bowl to rotate to a preset opening angle.

[0004] However, in the aforementioned technologies, due to factors such as component manufacturing tolerances and cumulative assembly errors, the actual opening angle of the reflector bowl often deviates from the theoretical design value, leading to problems such as beam defocus or blurred cut-off lines, which reduces the stability of the headlights and consequently the stability of the vehicle. Utility Model Content

[0005] This application provides a vehicle headlight assembly and a vehicle that can perform secondary adjustment of the opening angle of the reflector bowl to make the deviation between the opening angle of the reflector bowl and the theoretical design value smaller, thereby improving the integrity of the light pattern emitted by the headlight assembly and thus improving the operational stability of the headlight assembly and the vehicle.

[0006] On one hand, this application provides a vehicle lamp assembly, including a lamp holder, a reflector, a drive mechanism, an adjustment mechanism, and a fastening assembly; the lamp holder is used to connect to the vehicle body; the reflector is rotatably connected to the lamp holder; the drive mechanism is used to drive the reflector to rotate relative to the lamp holder to open the reflector, and the drive mechanism includes a gear ring; the adjustment mechanism includes a drive member and a transmission member, the drive member is rotatably engaged with the gear ring, the transmission member is connected to the gear ring, and the transmission member is drively connected between the drive member and the reflector, after the drive mechanism drives the reflector to open, the drive member can drive the transmission member to move and drive the reflector to rotate to change the opening angle of the reflector; the fastening assembly is connected to the gear ring, and the fastening assembly abuts against the drive member to prevent the drive member from disengaging from the gear ring.

[0007] Thus, after the drive mechanism completes the initial opening of the reflector bowl, the drive component in the adjustment mechanism can further drive the transmission component to dynamically fine-tune the opening angle of the reflector bowl. In other words, even with manufacturing or assembly deviations, subsequent compensation can bring the actual angle of the reflector bowl closer to the theoretical value, thereby ensuring the convergence and divergence characteristics of the light pattern distribution and the clarity of the cutoff lines. Furthermore, the limiting effect of the fastening components on the drive component, to a certain extent, prevents the risk of the drive component dislodging due to vibration or load changes during adjustment, enhancing the anti-interference capability of the adjustment mechanism.

[0008] As an optional implementation, the driving component is a worm gear, and the gear ring includes a gear ring body, a first mating part, and a second mating part. The transmission component is connected to the gear ring body. The worm gear includes a rod body with helical teeth formed on it. The first mating part has a groove that mates with the first end of the rod body, and a fastening component is connected to the first mating part. The second mating part includes a support sub-part and a mating sub-part connected together. The support sub-part has a support notch that supports the second end of the rod body. The second end of the rod body is connected to a hemispherical structure, and the mating sub-part has a hemispherical groove. The hemispherical structure and the hemispherical groove are rotatably engaged.

[0009] In this way, when the worm is rotated, a rotational engagement can be achieved between the worm and the first mating part and the second mating part, so that the worm can drive the sector gear to rotate.

[0010] As an optional implementation, the worm gear also includes an operating part, which is connected to the first end of the rod body, and an operating hole is provided at the end of the operating part opposite to the rod body.

[0011] In this way, external tools can apply force to the worm gear by cooperating with the operating hole, driving the worm gear to rotate, which in turn drives the sector gear to rotate, thereby adjusting the opening angle of the low beam reflector.

[0012] As an optional implementation, the fastening assembly includes a first fastener and a washer; the first fastener includes a first connecting post and a first end structure connected together, the diameter of the first end structure being larger than the diameter of the first connecting post; the first connecting post is connected to a first mating part, and the washer is disposed between the first mating part and the first end structure, and the washer abuts against the rod body.

[0013] In this way, the combination of the first fastener and the washer can limit the position of the worm, thereby preventing the worm from coming out of the first mating part and / or the second mating part to a certain extent and improving the stability of the worm in use.

[0014] As an optional implementation, the lamp holder is provided with multiple reflectors, which are arranged circumferentially along the lamp holder. The multiple reflectors include multiple low beam reflectors and multiple high beam reflectors, which are staggered. The driving mechanism can drive each low beam reflector and each high beam reflector to open, and one adjustment mechanism is set for each low beam reflector.

[0015] In this way, after each reflector is driven to open by the drive mechanism, the opening angle of the corresponding low beam reflector can be adjusted by the adjustment mechanism.

[0016] As an optional implementation, the transmission component is a sector gear, which is connected to the gear ring, and the outer circumference of the sector gear is connected to the worm gear drive. The headlight assembly also includes a drive shaft, a first gear, a second gear, and a drive rack. The axial direction of the drive shaft is consistent with the axial direction of the gear ring. The first gear is located at the first end of the drive shaft and meshes with the inner circumference of the sector gear. The second gear is located at the second end of the drive shaft. The drive rack meshes with the second gear and is connected to the corresponding low beam reflector.

[0017] In this way, after the drive mechanism opens each low beam reflector and each high beam reflector, the worm gear is rotated. The worm gear drives the sector gear to rotate around the center of the gear ring, which in turn drives the first gear and the second gear to rotate synchronously, thereby driving the transmission rack to move. Under the action of the transmission rack, the low beam reflector rotates slightly relative to the lamp holder to change the opening angle of the low beam reflector.

[0018] As an optional implementation, the vehicle lamp assembly provided in this application further includes a second fastener, which includes a second connecting post and a second end structure connected together, the diameter of the second end structure being larger than the diameter of the second connecting post; the sector gear includes a main body, on which a first strip hole is provided, the first strip hole extending circumferentially along the main body; the gear ring has a connecting end face facing away from the reflector bowl, and a protrusion is provided on the connecting end face, the protrusion passing through the first strip hole and slidingly engaging with the first strip hole; wherein, the second connecting post is connected to the protrusion, and the second end structure abuts against the main body.

[0019] In this way, by setting the second fastener and by engaging the protrusion with the first slot, the position of the sector gear can be limited in both the axial and radial directions of the gear ring, so as to ensure that the movement trajectory of the sector gear is a rotation around the center of the gear ring.

[0020] As an optional implementation, the main body includes a first sub-drive section and a second sub-drive section connected together; a first meshing tooth is formed on the first sub-drive section, and the first meshing tooth is connected to the helical tooth of the worm gear; a first strip hole is opened on the first sub-drive section; the second sub-drive section abuts against the inner peripheral wall of the gear ring, and a second meshing tooth is formed on the second sub-drive section, and the second meshing tooth is connected to the first gear.

[0021] In this way, on the one hand, the transmission connection between the sector gear and the worm gear, as well as the meshing connection between the sector gear and the first gear can be realized; on the other hand, through the blocking action of the second sub-transmission part and the inner peripheral wall of the gear ring, the position of the sector gear in the radial direction of the gear ring can be further limited, so as to improve the stability of the sector gear during use.

[0022] As an optional implementation, the first sub-drive unit includes a drive plate and a protruding plate connected together. A first meshing tooth is formed on the outer peripheral wall of the drive plate, and the inner peripheral wall of the drive plate is connected to the second sub-drive unit. A second strip-shaped hole is provided on the drive plate, which extends circumferentially along the sector gear. The second strip-shaped hole has an opening facing away from the connecting end face. The protruding plate is connected to the opening, and the outline shape of the protruding plate is the same as the shape of the opening. The first strip-shaped hole is provided on the protruding plate, and the protruding post passes through the second strip-shaped hole and the first strip-shaped hole in sequence.

[0023] In this way, on the one hand, the convex post can be matched with the first strip hole, and on the other hand, the connection between the transmission plate and the protruding plate can improve the structural strength of the first sub-transmission part, thereby improving the overall structural strength of the sector gear.

[0024] As an optional implementation, the drive mechanism further includes a drive motor and a drive gear. The drive motor is connected to the lamp holder and has an output shaft. The drive gear is disposed on the output shaft, and a protruding meshing portion is provided on the gear ring. The meshing portion has teeth, and the drive gear meshes with the teeth. The headlight assembly also includes a drive shaft, a first driven gear, a second driven gear, and a drive rack. The axial direction of the drive shaft is consistent with the axial direction of the gear ring. The first driven gear is disposed at the first end of the drive shaft and meshes with the inner circumferential wall of the gear ring. The second driven gear is disposed at the second end of the drive shaft. The drive rack meshes with the second driven gear and is drivenly connected to the corresponding high beam reflector.

[0025] When the motor starts, it drives the drive gear to rotate, which in turn drives the gear ring to rotate. Since the sector gear is connected to the gear ring, the sector gear and the gear ring will rotate synchronously, thereby driving the first driven gear and the second driven gear to rotate synchronously. The synchronous rotation of the first gear and the second gear causes the drive rack and the transmission rack to move. Under the action of the movement of the drive rack, the corresponding high beam reflector is driven to rotate relative to the lamp holder, so that the high beam reflector opens. Under the action of the movement of the transmission rack, the corresponding low beam reflector is driven to rotate relative to the lamp holder, so that the low beam reflector opens.

[0026] On the other hand, this application provides a vehicle including a body and the aforementioned headlight assembly.

[0027] The vehicle provided in this application, by adopting the aforementioned headlight assembly, can improve the stability of the vehicle in use. Attached Figure Description

Detailed Implementation

[0051] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0052] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0053] Headlights are the core component of a vehicle's lighting system, using internal optical components to precisely control the beam to meet driving safety requirements. The reflector, a key optical element of the headlight, uses a specific curved surface design to reflect light emitted from the light source and form a light pattern distribution that meets regulatory requirements. The opening angle of the reflector directly affects the focusing and diverging characteristics of the light pattern. In related technologies, the drive structure of the reflector typically employs a motor-driven gear transmission system. Specifically, the motor's output shaft is connected to a drive gear, which meshes with a ring gear. The inner ring of the ring gear has a toothed structure that engages with the meshing teeth at the top of the rotating shaft, while the meshing teeth at the bottom of the rotating shaft connect to a horizontal rack, which is connected to the reflector via a transmission connection. When the motor is running, power is transmitted sequentially through the gear, ring gear, rotating shaft, and rack, driving the reflector to rotate to a preset opening angle.

[0054] However, in the aforementioned technologies, due to factors such as component manufacturing tolerances and cumulative assembly errors, the actual opening angle of the reflector bowl often deviates from the theoretical design value, leading to problems such as beam defocus or blurred cut-off lines, which reduces the stability of the headlights and consequently the stability of the vehicle.

[0055] Based on this, this application provides a vehicle headlight assembly and a vehicle, which, after the reflector is initially opened, can have its opening angle adjusted a second time by an adjustment mechanism to ensure the convergence and divergence characteristics of the light pattern distribution and the clarity of the cutoff line, thereby improving the stability of the headlight and the stability of the vehicle.

[0056] It should be noted that the low beam reflector requires secondary adjustment because its beam pattern is strictly regulated. Even a slight angular deviation can cause the cutoff line to become blurred or cause glare. Dynamic compensation is necessary to ensure accurate light distribution. On the other hand, the high beam reflector is designed for wide-area illumination. Its beam diffusion characteristics can absorb angular tolerances and it is less sensitive to deviations, so no additional adjustment is required.

[0057] Based on this, in this embodiment of the application, the opening angle is adjusted by the adjustment mechanism for the near beam reflector.

[0058] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0059] Please combine Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the vehicle headlight assembly provided in an embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the local structure at point A. Figure 3 for Figure 1 Cross-sectional view along the BB direction. Figure 4 for Figure 1 The diagram shows the structure in another direction.

[0060] As shown in the figure, this embodiment provides a vehicle lamp assembly 100, including a lamp holder 1, a reflector 2, a drive mechanism 3, an adjustment mechanism 4, and a fastening component 5. The lamp holder 1 is used to connect to the vehicle body; the reflector 2 is rotatably connected to the lamp holder 1; the drive mechanism 3 is used to drive the reflector 2 to rotate relative to the lamp holder 1 to open the reflector 2, and the drive mechanism 3 includes a gear ring 31; the adjustment mechanism 4 includes a drive member 41 and a transmission member 42. The drive member 41 is rotatably engaged with the gear ring 31, and the transmission member 42 is connected to the gear ring 31 and is tractively connected between the drive member 41 and the reflector 2. After the drive mechanism 3 drives the reflector 2 to open, the drive member 41 can drive the transmission member 42 to move and drive the reflector 2 to rotate to change the opening angle of the reflector 2; the fastening component 5 is connected to the gear ring 31 and abuts against the drive member 41 to prevent the drive member 41 from disengaging from the gear ring 31.

[0061] Thus, after the drive mechanism 3 completes the initial opening of the reflector bowl 2, the drive component 41 in the adjustment mechanism 4 can further drive the transmission component 42 to dynamically fine-tune the opening angle of the reflector bowl 2. In other words, even if there are manufacturing or assembly deviations, subsequent compensation can still bring the actual angle of the reflector bowl 2 closer to the theoretical value, thereby ensuring the convergence and divergence characteristics of the light pattern distribution and the clarity of the cutoff line.

[0062] In addition, the limiting effect of the fastening component 5 on the drive component 41, to a certain extent, prevents the risk of the drive component 41 coming off due to vibration or load changes during the adjustment process, and enhances the anti-interference ability of the adjustment mechanism 4.

[0063] Understandably, the lamp holder 1 typically has multiple reflectors 2 arranged circumferentially around it. These reflectors 2 may include multiple low beam reflectors 2a and multiple high beam reflectors 2b, which are staggered. A driving mechanism 3 can open each low beam reflector 2a and each high beam reflector 2b, and an adjustment mechanism 4 is configured for each low beam reflector 2a. Thus, after each reflector 2 is opened by the driving mechanism, the opening angle of the corresponding low beam reflector 2a can be adjusted by the adjustment mechanism 4.

[0064] In the following description, for the sake of clarity, the near beam reflector 2a and the far beam reflector 2b will be described separately, and the reflector 2 will not be used.

[0065] Please continue to combine Figure 5 , Figure 5 This is a three-dimensional structural diagram of a first partial structure of the vehicle lamp assembly provided in an embodiment of this application. As shown in the figure, in some optional embodiments, the driving component 41 is a worm gear, the transmission component 42 is a sector gear, the sector gear is connected to the gear ring 31, and the outer periphery of the sector gear is connected to the worm gear for transmission.

[0066] Furthermore, the headlight assembly 100 provided in this embodiment also includes a drive shaft 6, a first gear 7, a second gear 8, and a drive rack 9; the axial direction of the drive shaft 6 is consistent with the axial direction of the gear ring 31; the first gear 7 is disposed at the first end of the drive shaft 6, and the first gear 7 is meshed with the inner circumferential side of the sector gear; the second gear 8 is disposed at the second end of the drive shaft 6; the drive rack 9 is meshed with the second gear 8, and the drive rack 9 is drivenly connected to the corresponding low beam reflector 2a.

[0067] Specifically, after the drive mechanism 3 drives each low beam reflector 2a and each high beam reflector 2b to open, the worm gear is rotated. The worm gear drives the sector gear to rotate around the center of the gear ring 31, which in turn drives the first gear 7 and the second gear 8 to rotate synchronously, thereby driving the transmission rack 9 to move. Under the action of the movement of the transmission rack 9, the low beam reflector 2a is driven to rotate slightly relative to the lamp holder 1, so as to change the opening angle of the low beam reflector 2a.

[0068] It should be noted that the worm gear can rotate in either a counterclockwise or clockwise direction. Specifically, when the worm gear rotates counterclockwise, the opening angle of the low beam reflector 2a increases; when the worm gear rotates clockwise, the opening angle of the low beam reflector 2a decreases. Alternatively, when the worm gear rotates counterclockwise, the opening angle of the low beam reflector 2a decreases; when the worm gear rotates clockwise, the opening angle of the low beam reflector 2a increases.

[0069] In order for the drive mechanism 3 to drive each low beam reflector 2a and each high beam reflector 2b to open, in some specific embodiments, the drive mechanism 3 also includes a drive motor 32 and a drive gear 33. The drive motor 32 is connected to the lamp holder 1 and has an output shaft 321. The drive gear 33 is disposed on the output shaft 321. The gear ring 31 has a connecting end face 314 facing away from the reflector 2. The connecting end face 314 is provided with a protruding meshing part 317. The meshing part 317 has teeth 3171. The drive gear 33 meshes with the teeth 3171.

[0070] Furthermore, the headlight assembly 100 provided in this embodiment also includes a drive shaft 10, a first driven gear 20, a second driven gear 30, and a drive rack 40. The axial direction of the drive shaft 10 is consistent with the axial direction of the gear ring 31. The first driven gear 20 is disposed at the first end of the drive shaft 10 and meshes with the inner peripheral wall of the gear ring 31. The second driven gear 30 is disposed at the second end of the drive shaft 10. The drive rack 40 meshes with the second driven gear 30 and is connected to the corresponding high beam reflector 2b.

[0071] When the motor starts, it drives the drive gear 33 to rotate, which in turn drives the gear ring 31 to rotate. Since the sector gear is connected to the gear ring 31, the sector gear and the gear ring 31 will rotate synchronously, thereby driving the first driven gear 20 and the second driven gear 30 to rotate synchronously, and the first gear 7 and the second gear 8 to rotate synchronously, so that the drive rack 40 and the transmission rack 9 move. Under the action of the drive rack 40, the corresponding high beam reflector 2b is driven to rotate relative to the lamp holder 1, so that the high beam reflector 2b opens. Under the action of the transmission rack 9, the corresponding low beam reflector 2a is driven to rotate relative to the lamp holder 1, so that the low beam reflector 2a opens.

[0072] That is, the number of drive shaft 10, first driven gear 20, second driven gear 30 and drive rack 40 is the same as the number of high beam reflectors 2b, and they correspond one-to-one; the number of transmission shaft 6, first gear 7, second gear 8 and transmission rack 9 is the same as the number of low beam reflectors 2a, and they correspond one-to-one.

[0073] Please continue to combine Figures 6 to 9 , Figure 6 This is a schematic diagram of the second partial structure of the vehicle lighting assembly provided in an embodiment of this application. Figure 7 for Figure 6 A magnified view of the local structure at point C. Figure 8 This is a three-dimensional structural diagram of the gear ring in the vehicle headlight assembly provided in this application embodiment. Figure 9 for Figure 8 A magnified view of the partial structure at point D. In some embodiments, the gear ring 31 includes a gear ring body 311, a first mating part 312, and a second mating part 313. A portion of the transmission component 42 is connected to the gear ring body 311. The worm gear includes a rod body 411 with helical teeth 4111 formed on it. The first mating part 312 has a groove 3121 that mates with the first end of the rod body 411. The fastening component 5 is connected to the first mating part 312. The second mating part 313 includes a support sub-part 3131 and a mating sub-part 3132 connected together. The support sub-part 3131 has a support notch 3133, which supports the second end of the rod body 411.

[0074] Please continue to combine Figures 10 to 12 , Figure 10 This is a three-dimensional structural diagram of the worm gear in the vehicle headlight assembly provided in an embodiment of this application. Figure 11 for Figure 8 A schematic diagram of the three-dimensional structure from another perspective. Figure 12 for Figure 11 A magnified view of the partial structure at point E. Further, a hemispherical structure 412 is connected to the second end of the rod body 411, and a hemispherical groove 3134 is formed in the mating part 3132. The hemispherical structure 412 and the hemispherical groove 3134 are rotatably engaged. Thus, when the worm is rotated, a rotatable engagement can be achieved between the worm and the first mating part 312 and the second mating part 313, enabling the worm to drive the sector gear to rotate.

[0075] Please continue to combine Figure 13 , Figure 13 for Figure 10A three-dimensional structural diagram from another perspective. It is understood that in order for the worm to rotate, a force needs to be applied to it to drive it to rotate. Therefore, in some optional embodiments, to facilitate the application of force to the worm, the worm also includes an operating part 413. The operating part 413 is connected to the first end of the rod body 411, and an operating hole 4131 is provided at the end of the operating part 413 facing away from the rod body 411. In this way, an external tool can apply a force to the worm by cooperating with the operating hole 4131, driving the worm to rotate, thereby driving the sector gear to rotate and adjusting the opening angle of the low-beam reflector 2a.

[0076] Please continue to combine Figure 14 , Figure 14 for Figure 7 A cross-sectional view along the FF direction. To allow the worm gear to disengage from the first mating part 312 and the second mating part 313 to a certain extent, the fastening assembly 5 includes a first fastener 51 and a washer 52. The first fastener 51 includes a first connecting post 511 and a first end structure 512 connected together, the diameter of the first end structure 512 being larger than the diameter of the first connecting post 511. The first connecting post 511 is connected to the first mating part 312, and the washer 52 is disposed between the first mating part 312 and the first end structure 512, and the washer 52 abuts against the rod body 411. Thus, the combination of the first fastener 51 and the washer 52 can limit the position of the worm gear, thereby preventing it from disengaging from the first mating part 312 and / or the second mating part 313 to a certain extent, improving the stability of the worm gear in use.

[0077] It should be noted that the first fastener 51 described above can be a screw. Of course, in some other embodiments, the first fastener 51 can also be a bolt, etc. Here, there is no limitation on the specific type of the first fastener 51.

[0078] Of course, in order for the sector gear to rotate around the center of the gear ring 31 under the drive of the worm gear, it is necessary to limit the axial position of the sector gear and the gear ring 31. Based on this, in some embodiments, the vehicle lamp assembly 100 provided in this embodiment further includes a second fastener 50, which includes a second connecting post 501 and a second end structure 502 connected together, wherein the diameter of the second end structure 502 is larger than the diameter of the second connecting post 501.

[0079] Furthermore, please combine Figure 15 and Figure 16 , Figure 15 This is a three-dimensional structural diagram of the sector gear in the vehicle headlight assembly provided in this application embodiment. Figure 16 for Figure 15A three-dimensional structural schematic diagram from another perspective. As shown, the sector gear includes a main body 421, on which a first strip-shaped hole 4211 is provided, extending circumferentially along the main body 421. The gear ring 31 has a connecting end face 314 facing away from the reflector bowl 2, and a protrusion 315 is provided on the connecting end face 314. The protrusion 315 passes through the first strip-shaped hole 4211 and slides in cooperation with it. A second connecting post 501 is connected to the protrusion 315, and a second end structure 502 abuts against the main body 421. Thus, by providing the second fastener 50 and by cooperating with the protrusion 315 and the first strip-shaped hole 4211, the position of the sector gear can be limited in both the axial and radial directions of the gear ring 31, ensuring that the movement trajectory of the sector gear is a rotation around the center of the gear ring 31.

[0080] Furthermore, the main body 421 includes a first sub-drive section 4212 and a second sub-drive section 4213 connected together. A first meshing tooth 4214 is formed on the first sub-drive section 4212, and the first meshing tooth 4214 is connected to the helical tooth 4111 of the worm gear. A first strip-shaped hole 4211 is formed on the first sub-drive section 4212. The second sub-drive section 4213 abuts against the inner peripheral wall of the gear ring 31, and a second meshing tooth 4215 is formed on the second sub-drive section 4213, which meshes with the first gear 7. In this way, on the one hand, the transmission connection between the sector gear and the worm gear, and the meshing connection between the sector gear and the first gear 7 can be realized; on the other hand, through the abutting action of the second sub-drive section 4213 against the inner peripheral wall of the gear ring 31, the radial position of the sector gear on the gear ring 31 can be further defined, thereby improving the stability of the sector gear during use.

[0081] To meet the structural strength requirements of the first sub-transmission unit 4212, in some optional embodiments, the first sub-transmission unit 4212 includes a transmission plate 4216 and a protruding plate 4217 connected together. A reinforcing plate 4220 is connected to the outer peripheral wall of the transmission plate 4216, and a first meshing tooth 4214 is formed on the outer peripheral wall of the reinforcing plate 4220. The inner peripheral wall of the transmission plate 4216 is connected to the second sub-transmission unit 4213. A second strip-shaped hole 4218 is provided on the transmission plate 4216. The second strip-shaped hole 4218 extends circumferentially along the sector gear. The second strip-shaped hole 4218 has an opening 4219 disposed opposite to the connecting end face 314. The protruding plate 4217 is connected to the opening 4219, and the outline shape of the protruding plate 4217 is the same as the shape of the opening 4219. The first strip-shaped hole 4211 is opened on the protruding plate 4217, and the protruding post 315 passes through the second strip-shaped hole 4218 and the first strip-shaped hole 4211 in sequence. In this way, on the one hand, the protrusion 315 can be matched with the first strip hole 4211, and on the other hand, the connection between the transmission plate 4216 and the protrusion plate 4217 can improve the structural strength of the first sub-transmission part 4212, thereby improving the overall structural strength of the sector gear.

[0082] The structure of the protruding post 315 can be as follows: the protruding post 315 includes a base post body 3151 and two spaced-apart positioning protrusions 3152. The first end of the base post body 3151 is connected to the connecting end face 314. A connecting hole 3153 is provided on the base post body 3151. The two positioning protrusions 3152 are connected to the second end of the base post body 3151, and the second connecting post 501 passes through the space between the two positioning protrusions 3152 and extends into the connecting hole 3153, connecting with the base post body 3151. The base post body 3151 has a second strip hole 4218, and the second end of the base post body 3151 is stopped by the protruding plate 4217. The positioning protrusions 3152 have a first strip hole 4211.

[0083] It should be noted that when the second fastener 50 is a threaded fastener, the aforementioned connecting hole 3153 is a threaded hole.

[0084] To improve the positioning reliability between the sector gear and the gear ring 31, the aforementioned protrusions 315 can be arranged along the extension direction of the first strip hole 4211, that is, the gear ring 31 can be arranged in multiple directions, such as two. Here, there is no specific limitation on the number of protrusions 315.

[0085] like Figure 16As shown, in order to improve the structural strength of the second sub-transmission unit 4213, in some specific embodiments, a plurality of reinforcing ribs 4230 are provided on the side of the inner peripheral wall of the second sub-transmission unit 4213 facing the gear ring 31. The plurality of reinforcing ribs 4230 are arranged at intervals along the circumference of the gear ring 31, and each reinforcing rib 4230 extends along the axial direction of the gear ring 31. In this way, by providing reinforcing ribs 4230, the structural strength of the second sub-transmission unit 4213 can be improved, thereby further improving the structural strength of the sector gear.

[0086] Please continue to combine Figure 17 and Figure 18 , Figure 17 for Figure 6 Cross-sectional view along the GG direction. Figure 18 for Figure 17 A magnified view of the partial structure at point H. In some optional embodiments, to improve the smoothness of the sector gear's rotation, two guide ribs 316 can be provided on the connecting end face 314. The two guide ribs 316 are distributed radially along the gear ring 31 on both sides of the second strip-shaped hole 4218, and each guide rib 316 extends circumferentially along the gear ring 31. Thus, by providing the guide ribs 316, the smoothness of the sector gear's rotation can be improved.
