Description

Technical Field

[0001] This application relates to vehicle manufacturing technology, and more particularly to a steering component and a vehicle. Background Technology

[0002] The steering mechanism of a vehicle (such as a scooter, bicycle, or motorcycle) is a core component affecting its handling, safety, and riding experience. Because electric scooters require a standing posture, the user's center of gravity is high. Furthermore, due to size limitations and ergonomic design, their trail is generally small. Therefore, the steering mechanisms of most models are overly sensitive, resulting in a light steering feel and difficulty in control. Additionally, when traversing uneven surfaces, if the steering mechanism is too sensitive, vibrations caused by the road surface will be transmitted to the steering mechanism, making it difficult to control the direction and potentially causing the rider to fall off the vehicle. In conclusion, an overly sensitive steering mechanism affects riding stability and poses a significant safety hazard. Utility Model Content

[0026] This application provides a steering assembly and a vehicle. The steering assembly includes a head tube, a riser tube, and a damper. A cavity is formed inside the head tube, and openings communicating with the cavity are formed at both ends of the head tube along its axial direction. The riser tube is used to connect to the steering operation unit of the vehicle and can rotate under the drive of the steering operation unit. At least a portion of the riser tube is rotatably inserted into the cavity through the opening. The damper is disposed in the cavity and includes a fixed member and a rotating member. The fixed member is sleeved on the outside of the rotating member, and an oil passage for filling damping oil is formed between the fixed member and the rotating member. The fixed member is connected to the head tube, and the rotating member is connected to the riser tube. When the riser tube rotates, it can drive the rotating member to rotate relative to the fixed member. This application places the damper within the cavity between the head tube and the riser. When the riser rotates, it drives the rotating component of the damper to rotate as well, while the fixed component of the damper remains stationary with the head tube. The rotation of the rotating component relative to the fixed component induces friction and shearing within the damping oil in the oil passages. This utilizes the viscous resistance of the damping oil to achieve a steering damping effect, reducing the sensitivity of the steering assembly and keeping it within a suitable sensitivity range. This improves driving stability and reduces riding risks. Furthermore, placing the damper within the head tube allows the head tube to protect the damper, extending its service life and enhancing the vehicle's aesthetics. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0053] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] As described in the background section, when a vehicle's steering components are overly sensitive, the vehicle's turning angle becomes excessive, making it difficult to control and potentially causing the driver to fall out. Furthermore, when traversing uneven road surfaces, the vibrations caused by the road surface are transmitted to the steering components, making steering difficult to control. Therefore, overly sensitive steering components affect driving stability and pose significant safety hazards.

[0055] In view of this, the embodiments of this application aim to provide a steering assembly and a vehicle. By placing the damper in the cavity between the head tube and the riser, when the riser rotates, it can drive the rotating component of the damper to rotate as a whole, while the fixed component of the damper is fixed to the head tube. When the rotating component rotates relative to the fixed component, it can induce friction and shearing within the damping oil in the oil passage. The viscous resistance of the damping oil is used to achieve a steering damping effect, reducing the sensitivity of the steering assembly, keeping the steering assembly within a suitable sensitivity range, improving driving stability, and reducing riding risks. In addition, placing the damper in the head tube of this application can protect the damper by utilizing the head tube, which is beneficial to extending the service life of the damper and improving the aesthetics of the vehicle's appearance.

[0056] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0057] Please refer to Figures 1-14 This embodiment provides a steering component 10, including:

[0058] The head tube 100, exemplarily, is generally cylindrical and may be made of a metallic material. A cavity 110 is formed inside the head tube 100, and openings 120 communicating with the cavity 110 are formed at both ends of the head tube 100 along the axial direction of the head tube 100.

[0059] A vertical tube 200 is used to connect to the vehicle's steering control unit 20, and the vertical tube 200 can rotate under the drive of the steering control unit 20. For example, the steering control unit 20 can be a handle. When the driver rotates the steering control unit 20, the vertical tube 200 rotates relative to the head tube 100. The vertical tube 200 is further connected to the vehicle's steering wheel, thereby achieving vehicle steering by rotating the steering control unit 20. In this embodiment, at least a portion of the vertical tube 200 is rotatably inserted into the cavity 110 through the opening 120.

[0060] A damper 300 is disposed within a cavity 110. The damper 300 includes a fixed member 310 and a rotating member 320. The fixed member 310 is sleeved on the outside of the rotating member 320, and an oil passage (not shown in the figure) for filling damping oil is formed between the fixed member 310 and the rotating member 320. The fixed member 310 is connected to the head tube 100, and the rotating member 320 is connected to the vertical tube 200. When the vertical tube 200 rotates, it drives the rotating member 320 to rotate relative to the fixed member 310, thereby causing the rotating member 320 to contact the damping oil in the oil passage. The viscous resistance of the damping oil will impede the rotation of the rotating member 320, thus achieving the effect of steering damping. It can be understood that the damping effect of the damper 300 can be changed by altering the size of the oil passage, the contact area between the rotating member 320 and the oil passage, the grade of the damping oil, and the amount of damping oil filling the oil passage.

[0061] In this embodiment, the damper 300 is disposed within the cavity 110 between the head tube 100 and the vertical tube 200. When the vertical tube 200 rotates, it drives the rotating component 320 of the damper 300 to rotate as a whole, while the fixed component 310 of the damper 300 is fixed to the head tube 100. When the rotating component 320 rotates relative to the fixed component 310, it can induce friction and shearing within the damping oil in the oil passage. The viscous resistance of the damping oil is used to achieve a steering damping effect, reducing the sensitivity of the steering assembly 10 and keeping the steering assembly 10 within a suitable sensitivity range, thereby improving driving stability and reducing riding risks. In addition, in this embodiment, disposing of the damper 300 within the head tube 100 allows the head tube 100 to protect the damper 300, which helps extend the service life of the damper 300 and improves the aesthetics of the vehicle's appearance.

[0062] Please continue to refer to Figures 1-12 In this embodiment, the fixing member 310 includes a housing, on which a first connecting portion 311 is provided. The first connecting portion 311 may, for example, be disposed on the outer surface of the housing. A first mating portion 130 is provided on the head tube 100, which may be disposed on the inner wall or end face of the head tube 100. The first connecting portion 311 is connected to the first mating portion 130. Exemplarily, the specific structure of the first connecting portion 311 and the first mating portion 130 can be configured as needed, for example, it can be a protrusion and groove fit, a threaded fit, etc.

[0063] The rotating component 320 includes a shaft core 321 located within a housing. A second connecting portion 322 is provided within the shaft core 321, which may be positioned within the projection range of the shaft core 321. A second mating portion 210 is provided on the vertical tube 200, and may be positioned on the outer surface of the vertical tube. The second connecting portion 322 connects to the second mating portion 210. Exemplarily, the specific structures of the second connecting portion 322 and the second mating portion 210 can be configured as needed, for example, as a protrusion-groove fit, a threaded fit, etc.

[0064] In this embodiment, the first connecting portion 311 includes a protrusion or groove on the housing, and the first mating portion 130 includes a groove or protrusion on the head tube 100. For example, as... Figures 1-12 As shown, the first connecting part 311 in this embodiment may be a protrusion provided on the housing, and the first mating part 130 may be a groove provided on the head tube 100. The connection between the fixing member 310 and the head tube 100 is achieved by inserting the protrusion into the groove.

[0065] In one possible implementation, such as Figures 1-8 As shown, the housing in this embodiment includes an outer shell 312 and an end cap 313, with the end cap 313 covering one end of the outer shell 312. A first connecting portion 311 is disposed on the end cap 313, and a first mating portion 130 is disposed on one end of the head tube 100. In this embodiment, multiple (e.g., two, three, etc.) first connecting portions 311 can be provided on the end cap 313, and the multiple first connecting portions 311 can be evenly arranged along the circumference of the end cap 313. Correspondingly, multiple first mating portions 130 can be provided on one end of the head tube 100, and the multiple first mating portions 130 and the multiple first connecting portions 311 are arranged in a one-to-one correspondence, with the multiple first connecting portions 311 respectively connected to the corresponding first mating portions 130.

[0066] Furthermore, in this embodiment, the end cap 313 is provided with a fixing groove 3131, and one end of the outer shell 312 is provided with a buckle 3121, which is engaged in the fixing groove 3131. In this embodiment, the end cap 313 may be provided with multiple (e.g., three, four, etc.) fixing grooves 3131, which are evenly arranged along the circumference of the end cap 313. Correspondingly, one end of the outer shell 312 may be provided with multiple buckles 3121, which correspond one-to-one with the multiple fixing grooves 3131, and are respectively engaged in the corresponding fixing grooves 3131.

[0067] In another possible implementation, such as Figures 9-12As shown, the housing in this embodiment includes an outer shell 312 and an end cap 313, with the end cap 313 covering one end of the outer shell 312. A first connecting portion 311 is disposed on the outer shell 312, and a first mating portion 130 is disposed on the inner wall of the head tube 100. In this embodiment, multiple (e.g., two, three, etc.) first connecting portions 311 can be disposed on the outer shell 312, and the multiple first connecting portions 311 can be evenly disposed along the circumference of the outer shell 312. Correspondingly, multiple first mating portions 130 can be disposed on the inner wall of the head tube 100, and the multiple first mating portions 130 and the multiple first connecting portions 311 are disposed in a one-to-one correspondence, with the multiple first connecting portions 311 respectively connected to the corresponding first mating portions 130.

[0068] Furthermore, in this embodiment, one end of the outer shell 312 is provided with a flange 3122, which abuts against the outer periphery of the end cap 313. Specifically, the diameter of the end cap 313 can be slightly smaller than the inner diameter of the outer shell 312. After the end cap 313 is assembled into the inner shell 312, the flange 3122 can be abutted against the end cap 313 by a spinning machine or other equipment, thereby preventing the end cap 313 from falling off.

[0069] In one possible implementation, the second connecting portion 322 of this embodiment includes a protrusion or groove disposed within the shaft core 321, and the second mating portion 210 includes a groove or protrusion disposed on the vertical tube 200. For example, please continue to refer to... Figures 1-4 , Figures 9-12 In this embodiment, the second connecting part 322 can be a protrusion provided in the shaft core 321, and the second mating part 210 can be a groove provided on the vertical tube 200. The connection between the rotating part 320 and the vertical tube 200 is realized by inserting the protrusion into the groove.

[0070] In this embodiment, the shaft core 321 may be provided with a plurality of (e.g., two, three, etc.) second connecting portions 322, which are evenly arranged along the inner wall of the shaft core 321. The corresponding vertical tube 200 may be provided with a plurality of second mating portions 210, which correspond one-to-one with the plurality of second connecting portions 322, and the plurality of second connecting portions 322 are respectively connected to the corresponding second mating portions 210.

[0071] Please continue to refer to Figures 1-4In this embodiment, the rotating component 320 further includes a frame 323, with a shaft core 321 sleeved on the outer periphery of the frame 323. A second connecting portion 322 is disposed on the inner wall of the frame 323, and the frame 323 is connected to the second mating portion 210 on the vertical tube 200 through the second connecting portion 322. In this embodiment, the steering assembly 10 passes through the opening 120 of the head tube 100. The frame 323 can be a metal frame and can be used to support external parts. The shaft core 321 can be, for example, a plastic part. The frame 323 can be press-fitted into the shaft core 321, or the frame 323 can be integrally formed with the shaft core 321 using an insert injection molding process.

[0072] Furthermore, to prevent the skeleton 323 from rotating within the shaft core 321, the outer periphery of the skeleton 323 in this embodiment is provided with at least one first limiting surface 3231, and the shaft core 321 is provided with at least one second limiting surface 3211, with the first limiting surface 3231 abutting against the second limiting surface 3211. It can be understood that by providing the first limiting surface 3231 and the second limiting surface 3211, the rotation of the skeleton 323 relative to the shaft core 321 can be restricted, thereby improving the stability of the connection between the two. For example, the cross-section of the skeleton 323 in this embodiment can be polygonal (e.g., pentagonal, hexagonal, etc.), thus giving the skeleton 323 multiple first limiting surfaces 3231; correspondingly, the cross-section of the through hole in the shaft core 321 is also polygonal, giving the shaft core 321 multiple second limiting surfaces 3211. The skeleton 323 can be interference-fitted with the shaft core 321.

[0073] Please continue to refer to Figures 5-8 In another possible implementation, the rotating member 320 of this embodiment further includes a frame 323, and the shaft core 321 is sleeved on the outer periphery of the frame 323. The second connecting part 322 includes a through hole provided on the frame 323, and the second mating part 210 includes a fixing hole provided on the vertical tube 200, the fixing hole being, for example, a threaded hole. In this embodiment, the shaft core 321 may be provided with a plurality of (for example, two, three, etc.) second connecting parts 322, and the plurality of second connecting parts 322 are evenly arranged along the outer periphery of the frame 323. The corresponding vertical tube 200 may be provided with a plurality of second mating parts 210, the plurality of second mating parts 210 corresponding one-to-one with the plurality of second connecting parts 322, and the plurality of second connecting parts 322 are respectively connected to the corresponding second mating parts 210.

[0074] Specifically, in this embodiment, the length of the frame 323 is greater than the length of the outer shell 312, and the frame 323 can be inserted into the outer shell 312. The first end of the frame 323 is used to connect with the shaft core 321. At least one first limiting surface 3231 is provided on the outer periphery of the first end of the frame 323, and at least one second limiting surface 3211 is provided inside the shaft core 321. The first limiting surface 3231 abuts against the second limiting surface 3211. The second connecting portion 322 can be located at the second end of the frame 323. The head tube 100 is provided with a through hole 140 corresponding to the second connecting portion 322. The fastener 400 passes through the through hole 140 and the second connecting portion 322 and is fixedly connected to the second mating portion 210. In this embodiment, the fastener 400 can be, for example, a bolt or screw.

[0075] Please continue to refer to Figures 1-12 The housing in this embodiment also includes an inner shell 314, and an outer shell 312 is fitted onto the outer periphery of the inner shell 314 and fixedly connected to it. The inner shell 314 contains a plurality of first labyrinth structures 3141. The shaft core 321 includes a rotating shaft 3212 and a damping portion 3213 fitted onto the outer periphery of the rotating shaft 3212. A plurality of second labyrinth structures 3214 are provided between the damping portion 3213 and the rotating shaft 3212. The plurality of first labyrinth structures 3141 are respectively inserted into the plurality of second labyrinth structures 3214, and the plurality of first labyrinth structures 3141 and the plurality of second labyrinth structures 3214 together form an oil passage.

[0076] In this embodiment, a portion of the rotating shaft 3212 extends out of the damping portion 3213, and the end cap 313 is fitted onto the outside of the extended portion of the rotating shaft 3212 and abuts against the end face of the damping portion 3213.

[0077] Exemplarily, the first labyrinth structure 3141 of this embodiment includes a protrusion or groove disposed within the inner shell 314, and the second labyrinth structure 3214 includes a groove or protrusion disposed within the damping portion 3213. By inserting the first labyrinth structure 3141 into the second labyrinth structure 3214, an oil passage is formed between adjacent protrusions and grooves to fill with damping oil.

[0078] Please continue to refer to Figure 4 In this embodiment, the outer shell 312 includes an outer shell bottom wall, on which a plurality of limiting holes 3123 are provided. The inner shell 314 includes an inner shell bottom wall, on which a plurality of limiting posts (not shown in the figure) are provided on the side of the inner shell bottom wall facing the outer shell bottom wall. The plurality of limiting posts are respectively interference connected to the plurality of limiting holes 3123, thereby realizing the assembly of the inner shell 314 and the outer shell 312.

[0079] Please continue to refer to Figure 4 , Figure 8 and Figure 12This embodiment also includes a seal 330, which is located at both ends of the oil passage. The seal 330 can be, for example, a sealing ring. Specifically, as... Figure 4 and Figure 8 As shown, the damper 300 includes two seals 330, which are located at both ends of the oil passage to prevent leakage of damping oil within the oil passage. Figure 12 As shown, the damper 300 includes three seals 330, which are located between the inner shell 314 and the shaft core 321, between the end cover 313 and the shaft core 321, and between the end cover 313 and the outer shell 312, respectively.

[0080] Please refer to Figures 13-14 This embodiment also provides a vehicle including the aforementioned steering assembly 10.

[0081] Specifically, the vehicle includes a steering operation unit 20 connected to the steering assembly 10, which may be, for example, a handle. The vehicle also includes a frame 30, a front wheel 40, and a rear wheel 50, with the front wheel 40 and rear wheel 50 respectively disposed on opposite sides of the frame 30. The steering assembly 10 is mounted on the frame near the front wheel 40, and the steering operation unit 20 is connected to the front wheel 40 via the steering assembly 10, thereby allowing control of the rotation direction of the front wheel 40.

[0082] Because the vehicle in this embodiment uses the aforementioned steering assembly 10, the steering assembly 10 can be kept within a suitable sensitivity range, improving driving stability and reducing riding risks. Furthermore, by placing the damper inside the head tube, this embodiment can protect the damper, extending its service life and enhancing the vehicle's aesthetics.
