Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically, to a vehicle with an adjustable steering wheel height. Background Technology

[0002] Vehicles are widely used as a common means of transportation. The operation and control of vehicles are usually done by gripping a steering wheel. Taking recreational vehicles such as go-karts as an example, their driving audience is relatively broad. Therefore, they are often unsuitable for drivers of different heights. This is because gripping the steering wheel too high or too low will cause a poor driving experience for the driver. In addition, a steering wheel of fixed height will result in a relatively fixed space occupation of the vehicle, which is not conducive to the storage of the vehicle. Utility Model Content

[0003] This utility model addresses the shortcomings of existing methods by proposing a vehicle with an adjustable steering wheel height, thereby solving the technical problems of poor driving experience and inconvenient storage caused by the non-adjustable steering wheel height in the prior art.

[0004] This utility model provides a vehicle with an adjustable steering wheel height, including a frame, a steering wheel component, and an adjustment assembly; The steering wheel component is rotatably mounted on the vehicle frame, and the adjustment component is mounted on the vehicle frame and acts on the steering wheel component. The adjustment component adjusts the tilt angle of the steering wheel component to adjust the height of the steering wheel component.

[0005] Optionally, the steering wheel component includes a grip, a connecting rod, a steering gear, and a kit; The hand grip is connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the frame via the steering gear. The kit is fitted onto the connecting rod and rotates in the circumferential direction of the connecting rod. The adjustment assembly includes a support member and a positioning member. One end of the support member is rotatably mounted on the frame, and the end of the support member away from the frame is used to support the kit. The kit has multiple fixing positions. The end of the positioning member away from the vehicle frame acts on different fixing positions to adjust the tilt angle of the steering wheel component. The positioning member is used to fix the end of the support member away from the vehicle frame to the kit.

[0006] Optionally, the adjustment assembly further includes a slider that is sleeved on the kit and slides along the length of the kit, and the end of the support member away from the frame is rotatably connected to the slider; The slider is provided with a first positioning hole, and the kit is provided with a plurality of second positioning holes forming the fixed position; The first positioning hole is aligned with a second positioning hole, and the positioning member is inserted into the aligned first positioning hole and second positioning hole.

The housing covers the sliding member so that the receiving cavity is connected to the first positioning hole. The positioning member is in the receiving cavity and aligned with the first positioning hole. The reset member is disposed in the receiving cavity. The reset member acts on the positioning member to drive the positioning member to insert into the first positioning hole and the second positioning hole. One end of the operating member is an abutting end, which is disposed in the receiving cavity. The other end is an operating end, which passes through the side wall of the receiving cavity and extends to the outside of the housing. The operating member moves relative to the housing. When an external force is applied to the operating end, the external force drives the operating member to move into the receiving cavity. The abutting end acts on the positioning member, and the positioning member disengages from the first positioning hole and the second positioning hole. The reset member stores energy. When the external force on the operating end is removed, the reset member releases and pushes the positioning member to reset and then inserts into the first positioning hole and the second positioning hole.

[0020] This utility model provides a vehicle with an adjustable steering wheel height, aiming to solve the above-mentioned technical problems of the prior art. The vehicle in this utility model is not specifically defined as a particular vehicle; for example, the vehicle can be, but is not limited to, go-karts, ATVs, etc.

[0021] The technical solution of this utility model and how the technical solution of this utility model solves the above-mentioned technical problems will be described in detail below with specific embodiments.

[0022] This utility model embodiment provides a vehicle with an adjustable steering wheel height, and the structural schematic diagram of the product is shown below. Figure 1 - Figure 7 As shown, it includes: a frame 10, a steering wheel component 20, and an adjustment component 30; the steering wheel component 20 is rotatably mounted on the frame 10, the adjustment component 30 is mounted on the frame 10 and acts on the steering wheel component 20, and the adjustment component 30 adjusts the elevation angle of the steering wheel component 20 to adjust the height of the steering wheel component 20.

[0023] As can be seen, the steering wheel component 20 is rotatably mounted on the vehicle frame 10. The steering wheel component 20 can rotate not only vertically but also circumferentially to facilitate steering operations. The vehicle frame 10 typically includes a vehicle body, wheels mounted on the vehicle body, and a seat (not shown), which will not be described further here. The steering wheel component 20 is rotatably mounted on the vehicle body and faces the seat. In this embodiment, the height of the top operating position of the steering wheel component 20 can be adjusted by adjusting the tilt angle of the adjusting assembly 30, thereby accommodating drivers of different heights. Furthermore, when storing the vehicle, the steering wheel component 20 can be adjusted to its lowest position using the adjusting assembly 30 to reduce space occupancy.

[0024] Optionally, the steering wheel component 20 includes a grip plate 21, a connecting rod 22, a steering gear 23, and a kit 24; the grip plate 21 is connected to one end of the connecting rod 22, and the other end of the connecting rod 22 is rotatably connected to the vehicle frame 10 via the steering gear 23; the kit 24 is sleeved on the connecting rod 22 and rotates in the circumferential direction of the connecting rod 22; the adjustment component 30 includes a support member 31 and a positioning member 32; one end of the support member 31 is rotatably disposed on the vehicle frame 10, and the end of the support member 31 away from the vehicle frame 10 is used to support the kit 24; the kit 24 is provided with multiple fixing positions, and the end of the positioning member 32 away from the vehicle frame 10 acts on different fixing positions to adjust the tilt angle of the steering wheel component 20; the positioning member 32 is used to fix the end of the support member 31 away from the vehicle frame 10 to the kit 24.

[0025] In this embodiment, multiple fixing points are arranged along the length of the kit 24. For ease of description, the end of the support member 31 away from the frame 10 is defined as the free end (top). The free end acts on different fixing points to adjust the tilt angle (i.e., elevation angle) of the kit 24, thereby ultimately achieving height adjustment of the handgrip 21.

[0026] It should be noted that the kit 24 does not move along the length of the connecting rod 22, and because the kit 24 interacts with the support 31, the kit 24 does not participate in the rotation of the connecting rod 22 when the connecting rod 22 rotates axially with the handgrip 21. This achieves the independent functions of height adjustment and rotation of the handgrip 21. In addition, after the free end interacts with the corresponding fixed position, the positioning member 32 fixes the free end to the kit 24, thus confirming the final height of the handgrip 21.

[0027] It can be seen that the closer the fixed position of the free end is to the hand grip 21 (that is, the highest fixed position), the lower the final height of the hand grip 21, and vice versa. In this way, multiple fixed positions can be set up to allow for more height adjustments.

[0028] Furthermore, when storing the vehicle, applying the free end to the highest fixed position will lower the grip plate 21 to its lowest position. Alternatively, the interaction between the free end and the fixed position can be directly released, allowing the grip plate 21 to rotate downwards to its lowest position, at which point the grip plate 21 can be hidden within the frame 10. In summary, this minimizes the space occupied in the height direction of the vehicle cover.

[0029] Preferably, the steering gear 23 is a universal joint. The universal joint can rotate vertically and also axially.

[0030] Optionally, combined Figure 2 - Figure 5 The adjustment component 30 also includes a slider 33, which is sleeved on the kit 24 and slides along the length of the kit 24. The end of the support member 31 away from the frame 10 is rotatably connected to the slider 33. The slider 33 is provided with a first positioning hole 330, and the kit 24 is provided with a plurality of second positioning holes 240 forming a fixed position. The first positioning hole 330 is aligned with one of the second positioning holes 240, and the positioning member 32 is inserted into the aligned first positioning hole 330 and second positioning hole 240.

[0031] In this embodiment, the aforementioned free end is connected to the kit 24 via the slider 33, so that the support 31 provides contact support to the kit 24, ensuring the stability of the hand grip 21.

[0032] At least one side wall of the kit 24 is provided with a second positioning hole 240. In this embodiment, three second positioning holes 240 are provided on one side wall of the kit 24 as an example. The three second positioning holes 240 are arranged along the length direction of the kit 24. A first positioning hole 330 is provided on the slider 33. Thus, the slider 33 slides along the length direction of the kit 24. During the movement, the first positioning hole 330 aligns with different second positioning holes 240. During this process, the elevation angle of the kit 24 changes continuously, and the height of the hand grip 21 is adjusted accordingly. The positioning member 32 passes through the aligned first positioning hole 330 and second positioning hole 240, and the sliding of the slider 33 ends.

[0033] Preferably, since the connecting rod 22 rotates with the hand grip 21, the kit 24 and the connecting rod 22 are connected in a mutually rotating manner. In order to avoid the kit 24 being affected by the rotation of the connecting rod 22, in this embodiment the kit 24 is a long rectangular sleeve. The sliding member 33 is adapted to the kit 24, but the sliding member 33 is a short rectangular sleeve. The sliding member 33 and the kit 24 form a right-angle locking position, thereby preventing the kit 24 from rotating with the connecting rod 22, ensuring the stability of the support member 31 and the reliability of vehicle operation.

[0034] Optionally, the adjustment assembly 30 further includes a cover 34, an operating member 35, and a reset member 36; the cover 34 has a receiving cavity inside, and the cover 34 covers the sliding member 33 so that the receiving cavity is connected to the first positioning hole 330. The positioning member 32 is in the receiving cavity and aligned with the first positioning hole 330. The reset member 36 is disposed in the receiving cavity. The reset member 36 acts on the positioning member 32 to drive the positioning member 32 to insert into the first positioning hole 330 and the second positioning hole 240. One end of the operating member 35 is an abutting end, which is disposed in the receiving cavity. The other end is an operating end, which passes through the side wall of the receiving cavity and extends to the outside of the cover 34. The operating member 35 moves relative to the cover 34. When an external force is applied to the operating end, the external force drives the operating member 35 to move into the receiving cavity. The abutting end acts on the positioning member 32, and the positioning member 32 disengages from the first positioning hole 330 and the second positioning hole 240. The reset member 36 stores energy. When the external force on the operating end is removed, the reset member 36 releases and pushes the positioning member 32 to reset and then inserts it into the first positioning hole 330 and the second positioning hole 240. The operating member 35 moves into the receiving cavity and resets.

[0035] This embodiment primarily achieves the positioning element 32 being mounted on the sliding element 33. The positioning element 32 is controlled to enter or exit the aligned first positioning hole 330 and second positioning hole 240 through the interaction of the operating element 35 and the reset element 36. This allows the positioning element 32 to move synchronously with the sliding element 33, facilitating positioning at any time and preventing loss of the positioning element 32. Preferably, the reset element 36 is a spring, which stores and releases energy through deformation.

[0036] Furthermore, as mentioned above, the operating end passes through the side wall of the receiving cavity and extends to the outside of the cover 34. It can be seen that the side wall of the receiving cavity is provided with a through hole. In order to prevent the operating part 35 from falling out of the cover 34, a locking protrusion 352 is provided on the side wall of the operating part 35, and the locking protrusion 352 abuts against the inner wall of the through hole.

[0037] Optionally, combined Figure 6 The positioning member 32 includes a base 321 and a plug post 322. The plug post 322 is disposed on the base 321 and faces the first positioning hole 330 and is aligned with the first positioning hole 330. The reset member 36 is disposed on the side of the base 321 away from the plug post 322. The base 321 is provided with a first inclined surface 3210 facing the first positioning hole 330, and the abutting end is provided with a second inclined surface 350. The second inclined surface 350 is fitted with the first inclined surface 3210. The movement direction of the operating member 35 is perpendicular to the movement direction of the positioning member 32.

[0038] In this embodiment, the initial state is that the plug-in pin 322 is inserted into the aligned first positioning hole 330 and second positioning hole 240. At this time, the first inclined surface 3210 and the second inclined surface 350 are in contact, and the locking protrusion 352 abuts against the inner wall of the through hole. When an external force is applied to the operating end, and the operating member 35 moves into the receiving cavity, the locking protrusion 352 disengages from the inner wall of the through hole, the first inclined surface 3210 and the second inclined surface 350 interact, the positioning member 32 moves away from the kit 24, and the plug-in pin 322 disengages from the first positioning hole 330 and the second positioning hole 240. At this time, the sliding member 33 can slide on the kit 24, and the reset member 36 compresses and stores energy. When the external force at the operating end is removed, the reset member 36 releases the pusher positioning member 32 to move in the direction of the assembly 24, the operating member 35 moves out of the receiving cavity, the insertion post 322 is inserted into the newly aligned first positioning hole 330 and second positioning hole 240, and the locking protrusion 352 is reset and abuts against the inner wall of the receiving cavity.

[0039] Alternatively, in another embodiment, the direction of movement of the operating member 35 can be parallel to the direction of movement of the positioning member 32.

[0040] It should be noted that the closer the second positioning hole 240 into which the plug pin 322 is inserted is to the hand grip 21, the smaller the elevation angle of the assembly 24, that is, the lower the height of the hand grip 21. If you want the height of the hand grip 21 to be as low as possible, you can use the operating member 35 to remove the plug pin 322 from the second positioning hole 240, and then slide the sliding member 33 as far as possible toward the hand grip 21.

[0041] Optionally, combined Figure 7There are two first inclined surfaces 3210 and two second inclined surfaces 350, with one second inclined surface 350 corresponding to one first inclined surface 3210; the two first inclined surfaces 3210 are respectively provided on both sides of the insertion post 322, and an abutment post 351 is provided on each side of the abutment end. One end of the two abutment posts 351 is respectively provided with a first inclined surface 3210, and a clearance space 3510 is formed between the two abutment posts.

[0042] As described above, the phase interaction between the operating member 35 and the base 321 is actually the interaction between the first inclined surface 3210 and the second inclined surface 350. The one-to-one correspondence between the two first inclined surfaces 3210 and the second inclined surface 350 in this embodiment increases the interaction point between the operating member 35 and the base 321, ensuring the stability when the operating member 35 pushes the base 321. The two first inclined surfaces 3210 are located on both sides of the insertion post 322, which ensures that the movement path of the insertion post 322 is a straight line, effectively ensuring that the insertion post 322 smoothly exits the mutually aligned first positioning hole 330 and second positioning hole 240.

[0043] Optionally, a guide groove 40 is provided in the receiving cavity, and a guide block 3211 adapted to the guide groove 40 is provided on the base 321; the cover 34 is slidably disposed in the guide groove 40.

[0044] For example, the receiving cavity is provided with two U-shaped bars with openings facing each other. The U-shaped grooves of the two U-shaped bars form a guide groove 40. Guide blocks 3211 are provided on two opposite sides of the base 321. One guide block 3211 is slidably disposed in one U-shaped groove. The reset member 36 is also disposed in the guide groove 40. The guide groove 40 is used to ensure the stability of the movement trajectory of the positioning member 32 and to ensure that the insertion post 322 can be accurately inserted into the aligned first positioning hole 330 and second positioning hole 240.

[0045] Optionally, the cover 34 includes a first sub-cover 341 and a second sub-cover 342; the first sub-cover 341 and the second sub-cover 342 are fastened to each other on the outer side of the slider 33 and form a receiving cavity between them.

[0046] The housing 34 is divided into a first sub-housing 341 and a second sub-housing 342. The first sub-housing 341 and the second sub-housing 342 are directly fastened together onto the kit 24, which facilitates installation. Additionally, the positioning member 32, the operating member 35, and the resetting member 36 are installed in the receiving cavity. More preferably, the base 321 is provided with a countersunk hole, into which the resetting member 36 is inserted. Preferably, the aforementioned U-shaped groove is provided in the first sub-housing 341.

[0047] In addition, multiple connecting lugs are provided at the joint between the first shell 341 and the second shell 342, and each connecting lug is screwed together.

[0048] Optionally, the kit 24 is rotatably mounted on the connecting rod via a bearing.

[0049] For example, the connecting rod 22 is a cylindrical rod, the inside of the kit 24 is a cylindrical channel, the inner ring of the bearing is interference-fitted to the cylindrical rod, and the outer ring of the bearing can also be interference-fitted to the cylindrical channel.

[0050] In this embodiment, bearings are provided at both ends of the cylindrical channel, and the two support points are used to improve the stability of the component 24 rotating on the connecting rod 22.

[0051] Optionally, the adjustment assembly 30 further includes a sliding sleeve 37 disposed between the kit 24 and the slider 33; the sliding sleeve 37 is provided with a through hole corresponding to the first positioning hole 330.

[0052] For example, the sliding sleeve 37 is typically made of a material with a low coefficient of friction, such as plastic. The sliding sleeve 37 can improve the smoothness of the sliding of the sliding component 33 relative to the kit 24.

[0053] In other solutions, as described above, the free end (top) of the support member 31 is displaced along the length of the kit 24, while the other end is simply rotated on the frame 10. However, in other solutions, the arrangement is reversed compared to the above embodiments. The free end is rotatably connected to the kit 24, while the other end (bottom) is displaced relative to the support, referring to the aforementioned free end. Specifically, the frame 10 is provided with a guide rod that aligns with the kit 24, and the guide rod is arranged along the front-rear direction of the frame 10. A sleeve with an alignment sliding member 33 is fitted onto the guide rod, and the sleeve slides relative to the guide rod. The support member 31 is rotatably mounted on the sleeve. Multiple adjustment positions, as described above, are also provided along the length of the guide rod. The sleeve moves between these adjustment positions, thus achieving the adjustment of the kit 24's elevation angle. The fixing member alignment positioning member 32 is used to fix the sleeve and the guide rod. Preferably, the adjustment positions can refer to the aforementioned adjustment holes, which will not be elaborated here.

[0054] Of course, both ends of the support member 31 can be set as free ends, so that both ends can be used to adjust the elevation angle of the kit 24 at the same time, as described above, and will not be repeated here.
