Description

Technical Field

[0001] This utility model relates to the field of steering shaft technology, and in particular to a steering shaft assembly for automobiles. Background Technology

[0002] The steering shaft is an important component of the car steering system. Its upper part is fixedly connected to the steering wheel, and its lower part is connected to the steering gear. It is used to transmit the steering force applied by the driver to the steering wheel to the steering gear. When equipped with a flexible universal joint, it can adjust the working angle and height of the steering wheel.

[0003] Chinese patent CN212709647U discloses a steering shaft for automobiles. The key technical features are: a cylindrical, hollow body with an external spline at its upper end and an internal spline I at its lower end. The external spline has parallel teeth. The body also contains an internal spline II, which has the same number of teeth as internal spline I. The inner end of internal spline I is connected to internal spline II via transition teeth on the inner wall of the body. The transition teeth have inclined grooves that correspond one-to-one with the grooves of internal splines I and II. The body has a radially convex convex section that transitions to the outer wall of the inner end of internal spline II via a conical surface. The convex section has an energy-absorbing collapsible structure. This invention offers advantages such as ease of mass assembly, good collapsible effect, and stable sliding force.

[0029] Reference Figures 1-4As shown, this utility model provides a technical solution: an automotive upper steering shaft assembly, including an upper shaft body 1. A fixing ring 2 is fixedly connected to the surface of the upper shaft body 1. Two sliding plates 3 are slidably connected to the inner wall of the fixing ring 2. Fastening screws 11 are threaded into the inner walls of both sliding plates 3. An arc plate 12 is rotatably connected to one end of each of the two fastening screws 11 near the upper shaft body 1. A stabilizing rod 13 is fixedly connected to one side of each of the two arc plates 12 near the fastening screws 11, and the stabilizing rod 13 is slidably connected to the inner wall of the sliding plate 3. By setting the fixing ring 2, the sliding plate 3 can be installed; by setting the fastening screws 11, the position of the arc plate 12 can be adjusted; and by setting the stabilizing rod 13, the rotation of the arc plate 12 can be restricted during its movement.

[0030] The following is a detailed explanation of its overall setup and function.

[0031] Reference Figures 1-4 As shown in this embodiment: Push plates 5 are fixedly connected to the ends of the two sliding plates 3 away from the fastening screws 11. Pads 14, made of rubber, are glued to the sides of the two arc plates 12 that are close to each other. The push plates 5 control the movement of the sliding plates 3, and the pads 14 improve the clamping effect of the two arc plates 12. Two mounting plates 4 are fixedly connected to the surface of the fixing ring 2. Adjusting screws 6 are rotatably connected to the sides of the two mounting plates 4 near the push plates 5, and the adjusting screws 6 are threaded into the inner wall of the push plates 5. The adjusting screws 6, rotatably connected to the mounting plates 4, can rotate on their surface, and the position of the push plates 5 can be adjusted by rotating the adjusting screws 6. Arc-shaped blocks 8 are installed on the sides of the two sliding plates 3 that are close to each other. The side of the arc-shaped blocks 8 away from the upper shaft body 1 is arc-shaped. The arc-shaped blocks 8 help the operator judge the connection effect between the upper shaft body 1 and the lower connecting shaft when connecting them.

[0032] A sliding rod 7 is fixedly connected to the side of the arc-shaped block 8 closest to the slide plate 3. The sliding rod 7 is slidably connected to the inner wall of the slide plate 3. The sliding rod 7, slidably connected to the inner wall of the slide plate 3, can move. By setting the sliding rod 7, the connection between the arc-shaped block 8 and the slide plate 3 is ensured, while also allowing the arc-shaped block 8 to move. A circular plate 9 is fixedly connected to the end of the sliding rod 7 furthest from the arc-shaped block 8. By setting the circular plate 9, the stable installation of the sliding rod 7 is ensured, and the movement of the sliding rod 7 can be easily controlled. A spring 10 is fitted onto the surface of the sliding rod 7, and both ends of the spring 10 are fixedly connected to the circular plate 9 and the slide plate 3, respectively. By setting the circular plate 9, the spring 10 can be installed, and the spring 10 can restrict the position of the sliding rod 7.

[0033] Working principle: When connecting the upper shaft body 1 and the lower steering shaft, the lower steering shaft is moved closer to the connecting upper shaft. During this process, the lower steering shaft pushes the arc-shaped block 8, causing the slide rod 7 to slide on the inner wall of the slide plate 3. The circular plate 9 moves away from the slide plate 3. When the lower steering shaft is inserted into the installation position inside the upper shaft body 1, under the action of the spring force of the spring 10, the arc-shaped block 8 moves closer to the lower steering shaft. At this time, the movement of the lower steering shaft can be stopped. The fastening screw 11 is rotated to make it rotate on the inner wall of the slide plate 3. At this time, under the restriction of the stabilizing rod 13, the arc plate 12 and the pad 14 move closer to the lower steering shaft to clamp the lower steering shaft. When it is necessary to separate the connecting upper shaft and the lower steering shaft, the arc-shaped block 8 is moved away from the lower steering shaft, and the adjusting screw 6 is rotated to make it slide on the inner wall of the push plate 5 and the mounting plate 14. The surface of mounting plate 4 rotates, thereby controlling the sliding plate 3 to slide on the inner wall of fixing ring 2, thereby pushing the lower steering shaft away from the connecting upper shaft and completing the separation of the lower steering shaft. By setting fixing ring 2 and mounting plate 4, sliding plate 3, push plate 5 and fastening screw 11 can be installed. By setting fastening screw 11, arc plate 12 and pad 14, the lower steering shaft can be clamped. By setting adjusting screw 6 and push plate 5, sliding plate 3 can be pushed to drive the lower steering shaft away from the upper shaft body 1, realizing the separation of the two. By setting circular plate 9, spring 10, slide rod 7 and arc block 8, a positioning effect can be achieved when connecting upper shaft body 1 and lower steering shaft, thereby assisting the staff to judge the connection effect between upper shaft body 1 and lower steering shaft.
