Description

Technical Field

[0001] The present application relates to the technical field of steering wheels, and in particular to a steering wheel suitable for drivers with a missing distal thumb joint. Background Art

[0002] The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" stipulate that individuals with missing fingertips or a missing right thumb can still apply for a driver's license for small cars (C1), small automatic cars (C2), and low-speed trucks (C3). This regulation reflects inclusiveness for people with different physical conditions and aims to allow more people to obtain driving qualifications, as long as their physical conditions meet the basic requirements for safe driving.

[0003] However, a missing distal thumb joint can affect a driver's precision in steering, shifting gears, and braking. This is especially true in situations requiring strong finger strength and fine motor skills. Loss of the distal thumb joint reduces grip strength and makes driving difficult. For drivers with a missing distal thumb joint, prolonged driving can lead to fatigue and increase safety risks. Therefore, some drivers may need some time to adapt before becoming proficient in driving techniques.

[0004] While existing vehicle modifications and assisted driving systems exist for people with disabilities, there are no steering wheels specifically designed for people with distal thumb loss. Currently, most steering wheels on the market are still designed based on the needs of ordinary drivers, failing to consider the specific needs of some people with specific physical conditions. For people with distal thumb loss, traditional steering wheel designs can present issues such as an unstable grip and awkward control, failing to provide adequate comfort and safety.

Figure 2 As shown) and the second channel 202 (i.e., the channel between the right disk 4 and the second sliding sleeve structure 6, as shown) Figure 3 As shown), the first channel 201 is used for the first sliding sleeve structure 5 to pass through, and the second channel 202 is used for the second sliding sleeve structure 6 to pass through.

[0042] See also Figure 4 A first slide rail 105 (i.e., a slide rail between the left disc width 3 and the first sliding sleeve structure 5) and a second slide rail 106 (i.e., a slide rail between the right disc width 4 and the second sliding sleeve structure 6) are fixedly arranged inside the steering wheel rim 1. The first slide rail 105 and the second slide rail 106 are symmetrically distributed relative to the center of the steering wheel rim 1. A third channel 101 (i.e., a channel between the left disc width 3 and the first sliding sleeve structure 5) is opened on the inner side of the steering wheel rim 1.

[0043] See also Figure 5A motor 7, a first gear 8, a second gear 9 and a third gear 10 are fixedly arranged inside the steering wheel column 2, the output shaft of the motor 7 is fixedly connected to the first gear 8, the second gear 9 and the third gear 10 are both meshed with the first gear 8, and the second gear 9 and the third gear 10 are symmetrically distributed relative to the center of the first gear 8 axis; one end of the first sliding sleeve structure 5 is fixedly connected to the output shaft of the second gear 9, and the other end of the first sliding sleeve structure 5 is slidably connected to the first slide rail 105, and the end of the first sliding sleeve structure 5 located inside the steering wheel rim 1 is fixedly provided with a first bracket 501; one end of the second sliding sleeve structure 6 is fixedly connected to the output shaft of the third gear 10, and the other end of the second sliding sleeve structure 6 is slidably connected to the second slide rail 106, and the end of the second sliding sleeve structure 6 located inside the steering wheel rim 1 is fixedly provided with a second bracket 601, the first opening 103 is used to push out the first bracket 501, and the second opening 104 is used to push out the second bracket 601, wherein the first bracket 501 and the second bracket 601 are hook-shaped brackets.

[0044] Specifically, in a steering wheel suitable for drivers with a missing distal thumb joint, the present application provides a first sleeve structure 5 comprising an inner rod and an outer sleeve. One end of the inner rod is fixedly connected to the output shaft of the second gear 9, and the other end is mounted with the outer sleeve. The outer sleeve fits within a first slide rail 105 and can slide along the first slide rail 105 driven by the inner rod. A first bracket 501 is fixed to the outer sleeve. As the outer sleeve slides along the slide rail, it gradually extends and delivers the first bracket 501. In the present application, the second sleeve structure 6 and the first sleeve structure 5 have the same structure and will not be further described here.

[0045] The main working principle of a steering wheel suitable for drivers with a missing thumb joint provided by the present application is as follows: the motor 7 drives the first gear 8 above to rotate clockwise, and when the first gear 8 moves, it drives the second gear 9 and the third gear 10 meshing with it to rotate counterclockwise. At the same time, the first sleeve structure 5 and the second sleeve structure 6 connected to the second gear 9 and the third gear 10 rotate with the gear shaft as the center of the circle, so that the first sleeve structure 5 and the second sleeve structure 6 perform a limiting movement in the grooves of the first slide rail 105 and the second slide rail 106, and finally stop at the ends of the first slide rail 105 and the second slide rail 106, and push out the first bracket 501 and the second bracket 601 respectively, so that they pop out on both sides of the steering wheel rim 1, thereby supporting the ulnar side of the palms of the motor vehicle driver with a missing thumb joint, adding a fulcrum for the palm, and compensating for the problem of unstable grip caused by insufficient thumb strength.

[0046] See also Figure 6 and Figure 7The present application provides a steering wheel suitable for drivers with a missing distal joint of the thumb, and also includes a display screen 11 and a lifting mechanism 12. The display screen 11 is installed on the top of the steering column 2 of the steering wheel through the lifting mechanism 12, and the lifting mechanism 12 can control the up and down movement of the display screen 11; the lifting mechanism 12 includes a fourth gear 121, a fifth gear 122, a sixth gear 123, a first rack 124 and a second rack 125, the fourth gear 121 is coaxially fixedly connected to the first gear 8, the fifth gear 122 and the sixth gear 123 are vertically meshed with the fourth gear 121, the first rack 124 is meshed with the fifth gear 122, and the second rack 125 is meshed with the sixth gear 123. The first rack 124 and the second rack 125 can move up and down under the drive of the fifth gear 122 and the sixth gear 123, and the fixed ends of the first rack 124 and the second rack 125 are fixedly connected to the display screen 11.

[0047] The present application provides a steering wheel suitable for drivers with missing distal joints of the thumb. While pushing out the first bracket 501 and the second bracket 601, the fourth gear 121 coaxial with the motor 7 and the first gear 8 is also driven to move clockwise. The rotation of the fourth gear 121 will drive the fifth gear 122 and the sixth gear 123 to rotate. The rotation of the fifth gear 122 and the sixth gear 123 will drive the first rack 124 and the second rack 125 to move up and down in the vertical direction. Because the fixed ends of the first rack 124 and the second rack 125 are fixed to the display screen 11, they will control the display screen 11 to move up and down.

[0048] The upward movement of the display screen 11 brings the display screen 11 approximately 150 mm closer to the driver, thereby enhancing the visual interaction experience for people with disabilities. (Due to thumb loss, driving posture is restricted, and the 150 mm displacement flexibility of the display screen 11 plays a significant role in improving visual ergonomics.) When the first bracket 501 and the second bracket 601 reach the ends of the first and second slide rails 105 and 106, the display screen 11 stops moving, and the motor 7 stops operating. The user can then place their palms on the hook-shaped brackets at both ends to help stabilize the steering wheel, avoiding accidents caused by the inability to grip the steering wheel due to the loss of fingers.

[0049] See also Figure 8 The present application provides a steering wheel suitable for drivers with a missing distal thumb joint. The steering wheel also includes a partition 203 that divides the interior of the steering column 2 into an upper cavity and a lower cavity. The motor 7, first gear 8, second gear 9, and third gear 10 are disposed in the lower cavity, while the fourth gear 121, fifth gear 122, sixth gear 123, first rack 124, and second rack 125 are disposed in the upper cavity. The free ends of the first rack 124 and the second rack 125 extend into the lower cavity through a through hole in the partition 203.

[0050] Continue reading Figure 2 The present application provides a steering wheel suitable for drivers with a missing distal joint of the thumb. A first receiving cavity 301 is provided on one side of the left wheel width 3. The first receiving cavity 301 is used to receive the first sliding sleeve structure 5. A second receiving cavity 401 is provided on one side of the right wheel width 4. The second receiving cavity 401 is used to receive the second sliding sleeve structure 6.

[0051] See also Figure 9 In a steering wheel suitable for drivers with a distal thumb joint defect, the present application provides a steering wheel rim 1 comprising an upper rim 107 and a lower rim 108. The upper rim 107 and the lower rim 108 are fixedly connected on one side by a rotating shaft 109, and the upper rim 107 and the lower rim 108 are fixedly connected on the other side by a connecting ring 110. With this structural design, the driver can first remove the connecting ring 110, then rotate the lower rim 108 90 degrees around the rotating shaft 109 and secure it, making it easier for the driver to rest or get off the vehicle.

[0052] Because the palm of the hand with a damaged thumb joint only has four fingers contacting the steering wheel, the hand is more likely to get tired. In this state, when arriving at the destination or taking a break during driving, the user can fold the lower rim 108 of the steering wheel upwards and lock it (such as Figure 10 This can increase the leg room, making it easier to rest and get off the vehicle; secondly, the raised part makes it easier for the driver to lie on it to rest or change the position of his hands, forming a humanized driving space.

[0053] It should be noted that when the lower rim 108 of the steering wheel is folded upward, the first and second sliding sleeve structures 5 and 6 are both retracted into the first and second receiving cavities 301 and 401, thus having no impact on the lower rim. Furthermore, after the lower rim 108 of the steering wheel 1 is folded upward, the left side is connected to the rotating shaft 109, while the right side is completely disconnected from the upper rim 107, allowing the lower rim to fully support one arm for the driver to rest.

[0054] In a steering wheel suitable for drivers with a missing distal joint of the thumb provided in the present application, the upper rim 107 and the lower rim 108 can also be folded by a ratchet pawl. The pawl can slide between the teeth of the ratchet, thereby allowing the upper rim 107 and the lower rim 108 to move relative to each other in a certain direction, while being locked in another direction.

[0055] See also Figure 11The present application provides a steering wheel suitable for drivers with a missing distal thumb joint. A switch button 13 is fixedly mounted on the right side of the lower outer surface of the steering column 2. The switch button 13 is electrically connected to the motor 7 and is used to control the motor 7 on and off. This manually activated mechanical transmission system avoids the reliance on the vehicle's computer settings and electronic control system, as is the case with conventional telescopic steering wheels. This is energy-efficient and environmentally friendly, and is easily repairable if damaged.

[0056] This application provides a steering wheel suitable for drivers with distal thumb joint loss. After getting in the vehicle, the driver presses a button on the right-hand side of the steering column 2 to activate barrier-free mode. A first support 501 and a second support 601 extend from either side of the steering wheel rim 1 to support the ulnar side of both palms, providing a support point and a point of force for the palms. In this mode, the driver can also manually tilt the lower rim 108 upwards to create an angle with the upper rim 107, allowing for adequate rest.

[0057] The steering wheel provided in this application, suitable for drivers with distal thumb joint amputations, utilizes built-in slide rails, compared to methods that use telescopic structures or directly extend auxiliary supports. The advantage is that it increases the travel of the support and significantly reduces the possibility of accidental ejection. This structure is easy to manufacture and maintain, and can reduce sales and repair costs. The relatively simple mechanical structure also helps reduce resource consumption, which is common in precision machining.

[0058] The present application provides a steering wheel suitable for drivers with a missing distal joint of the thumb. Small hook-shaped supports extend from both sides of the steering wheel to support the ulnar side of both palms, thereby adding a fulcrum for the palms. This compensates for the unstable grip caused by insufficient thumb strength of drivers with a missing distal joint of the thumb, making driving a vehicle safer and more reliable.

[0059] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
