Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive steering shaft technology, specifically to an automotive steering shaft positioning device. Background Technology
[0002] The steering shaft is the core component of the car steering system, and its performance is directly related to traffic safety and personal safety. During the driving process, drivers have significant differences in height, body type and operating habits.
[0003] However, traditional automotive steering shaft positioning devices often employ a fixed-angle design, making it difficult to meet diverse ergonomic needs. In existing technologies, the installation angle of the steering shaft is typically fixed during the vehicle development stage. Drivers cannot adjust the steering wheel position according to their own height, forcing taller drivers to bend over due to the steering wheel obstructing their view of the instrument panel, increasing neck strain; shorter drivers, on the other hand, must extend their arms to operate the steering wheel, which can easily lead to shoulder fatigue during prolonged driving. For users with significant differences in arm length, a fixed steering shaft structure may cause overextension or constriction of the arms, affecting handling precision and even delaying steering timing in emergency situations due to excessively long operating paths.
[0004] To address this issue, we designed an automotive steering shaft positioning device. Utility Model Content
[0005] The purpose of this invention is to provide an automotive steering shaft positioning device to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides an automotive steering shaft positioning device, including a fixing plate, a support frame at the top of the fixing plate, a first through groove on the left and right sides of the top of the support frame, a second through groove on the front and rear sides of the bottom of the support frame, a first shaft hole through the front and rear sides of the first through groove, a first limiting shaft rotatably inserted into the first shaft hole, the bottom end of the steering shaft being disposed in the first through groove, and a second shaft hole through the left and right sides of the second through groove, a second limiting shaft rotatably inserted into the second shaft hole.
[0007] Furthermore, both ends of the first and second limiting shafts are provided with threaded lines.
[0008] Furthermore, the first limiting shaft is threaded with a first nut at both ends, and the second limiting shaft is threaded with a second nut at both ends.
[0009] Furthermore, a fixed shaft is fixedly connected to the top end of the fixed plate, and a rotating shaft is rotatably connected to the top end of the fixed shaft.
[0010] Furthermore, slots are provided on both the left and right sides of the rotating shaft, and the second limiting shaft is tightly inserted into the slots.
[0011] Furthermore, a bolt is threadedly connected between the anti-detachment groove and the anti-detachment shaft.
[0012] Furthermore, a convex anti-detachment groove is provided inside the fixed shaft.
[0013] Furthermore, an anti-detachment shaft is fixedly connected to the bottom end of the rotating shaft, and the shape of the anti-detachment shaft is adapted to the anti-detachment groove.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. In this utility model, the adjusting device composed of the first through groove, the first limiting shaft, and the first nut can flexibly adjust the left and right angles of the steering shaft, improving visibility and ease of operation while driving. The adjusting structure composed of the second through groove, the second limiting shaft, and the second nut can easily change the front and rear angles of the steering shaft, meeting the needs of drivers with different arm lengths. This allows the arm movement range of drivers of different body types to match the steering wheel travel. In emergencies, larger drivers can avoid arm-to-abdomen collisions, while smaller drivers can shorten the steering path and improve response speed for emergency maneuvers such as sharp turns, indirectly enhancing driving safety.
[0016] 2. In this utility model, the rotation adjustment device formed by the fixed shaft, the rotating shaft and the anti-detachment groove can adjust the steering shaft in 360 degrees circumferentially to adapt to the hand grip habits of different drivers. For example, left-handed drivers or drivers who prefer a specific grip can finely adjust the steering wheel angle to make the hand posture more natural and improve the comfort and stability of driving control.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-3 This utility model provides a technical solution: a car steering shaft positioning device, including a fixing plate 1, a support frame 2 at the top of the fixing plate 1, a first through groove 3 on the left and right sides of the top of the support frame 2, a second through groove 4 on the front and rear sides of the bottom of the support frame 2, a first shaft hole 5 through the front and rear sides of the first through groove 3, a first limiting shaft 7 rotatably inserted into the first shaft hole 5, the bottom end of the steering shaft is set in the first through groove 3 and tightly sleeved in the middle position of the first limiting shaft 7, a second shaft hole 6 through the left and right sides of the second through groove 4, a second limiting shaft 8 rotatably inserted into the second shaft hole 6, both ends of the first limiting shaft 7 and the second limiting shaft 8 are threaded, the two ends of the first limiting shaft 7 are threaded with a first nut 9, and the two ends of the second limiting shaft 8 are threaded with a second nut 10.
[0024] In practice, if the driver needs to rotate the steering shaft to adjust the steering wheel position according to their body shape, the operator first loosens the first nut 9 to release the first limiting shaft 7 from the first shaft hole 5, based on the required steering shaft angle. The steering shaft is then moved left and right within the first through groove 3 to adjust its left and right angle to the target position. The first nut 9 is then tightened to lock the first limiting shaft 7 within the first shaft hole 5, thus fixing the left and right angle of the steering shaft. Next, the second nut 10 is loosened to release the second limiting shaft 8 from the second shaft hole 6. The steering shaft is then moved back and forth within the second through groove 4 to adjust its front and rear angle to the target position. Finally, the second nut 10 is tightened to lock the second limiting shaft 8 within the second shaft hole 6, thus positioning the front and rear angle of the steering shaft.
[0025] See Figure 1 The top of the fixed plate 1 is fixedly connected to a fixed shaft 11, and the top of the fixed shaft 11 is rotatably connected to a rotating shaft 12. The left and right sides of the rotating shaft 12 are provided with slots 13. The second limiting shaft 8 is tightly inserted into the slot 13. The anti-disengagement groove 14 and the anti-disengagement shaft 15 are threadedly connected with bolts.
[0026] In practice, if it is necessary to rotate the steering shaft, the operator loosens the bolts between the anti-detachment groove 14 and the anti-detachment shaft 15 to release the circumferential lock on the rotating shaft 12. At this time, the rotating shaft 12 can rotate 360 degrees within the fixed shaft 11, driving the second limit shaft 8 and the steering shaft to rotate synchronously. After rotating to the target position, tighten the bolts, and through the cooperation between the anti-detachment shaft 15 and the anti-detachment groove 14, lock the rotating shaft 12 within the fixed shaft 11, completing the rotational positioning of the steering shaft.
[0027] See Figure 4 The fixed shaft 11 has a convex anti-detachment groove 14, and the bottom end of the rotating shaft 12 is fixedly connected to the anti-detachment shaft 15. The shape of the anti-detachment shaft 15 is adapted to the anti-detachment groove 14. The anti-detachment shaft 15 is rotatably connected in the anti-detachment groove 14. This design can prevent the rotating shaft 12 from detaching from the fixed shaft 11 during rotation.
[0028] Working principle: According to the required steering shaft angle, the operator first loosens the first nut 9 to release the first limiting shaft 7 from the first shaft hole 5. By swinging the steering shaft left and right in the first through groove 3, its left and right angle is adjusted to the target position. Then, the first nut 9 is tightened to lock the first limiting shaft 7 in the first shaft hole 5, thus fixing the left and right angle of the steering shaft.
[0029] Next, loosen the second nut 10 to release the second limiting shaft 8 from the second shaft hole 6. Swing the steering shaft back and forth in the second through groove 4 to adjust its front and rear angle to the target position. Then tighten the second nut 10 to lock the second limiting shaft 8 in the second shaft hole 6, thereby achieving the positioning of the front and rear angle of the steering shaft.
[0030] If rotation of the steering shaft is required, the operator loosens the bolts between the anti-detachment groove 14 and the anti-detachment shaft 15 to release the circumferential lock on the rotating shaft 12. At this time, the rotating shaft 12 can rotate 360 degrees within the fixed shaft 11, driving the second limit shaft 8 and the steering shaft to rotate synchronously. After rotating to the target position, tighten the bolts, and through the cooperation of the anti-detachment shaft 15 and the anti-detachment groove 14, lock the rotating shaft 12 within the fixed shaft 11, completing the rotational positioning of the steering shaft.
[0031] Throughout the positioning process, the first through groove 3 and the second through groove 4 provide space for the left and right and front and rear angle adjustments of the steering shaft, respectively. The shaft hole mating structure of the first shaft hole 5 with the first limiting shaft 7, the second shaft hole 6 with the second limiting shaft 8, and the anti-disengagement structure of the fixed shaft 11 and the rotating shaft 12 ensure that the steering shaft can be reliably locked after adjustment in different directions, meeting the requirements of the automotive steering system for the positioning accuracy and stability of the steering shaft, as well as the body shape and habits of different drivers.
[0032] An adjustable steering shaft positioning device allows the range of arm movement of drivers of different sizes to match the steering wheel travel. In an emergency, it can prevent the arms and abdomen of larger drivers from colliding, while it can shorten the steering operation path for smaller drivers and improve the response speed of emergency operations such as sharp steering, thereby indirectly enhancing driving safety.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
