Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 , a technical solution provided by the utility model:

[0022] Example 1:

[0023] A vibration-proof structure of a power steering controller includes a steering main frame 1, a connecting shaft 2 is installed on the top of the steering main frame 1, a buffer assembly 3 is connected to the top of the steering main frame 1 through the connecting shaft 2, the outer wall of the steering main frame 1 is connected to a drive rod 4 through the connecting shaft 2, one end of the drive rod 4 is connected to a mounting frame 5 by a bearing, a single-sided vibration damping assembly 6 is installed on one side of the mounting frame 5, a steering wheel 7 is installed on the outside of the single-sided vibration damping assembly 6, and one end of the buffer assembly 3 is connected to a connecting rod 8.

[0024] The two sets of bracket structures designed on the left and right of this structure can independently resist vibration on both sides of the steering gear. The middle position is connected by the buffer component 3, which can resist vibration on the left and right mounting brackets 5. When on bumpy roads, the middle buffer component 3 can be compressed. The driving rod 4 and the bearing design of the buffer component 3 can be used to lift one side of the drive control bracket to keep the other side stable, reducing the overall vibration of the controller body, thereby achieving a shock absorption effect.

[0025] Furthermore, the interior of the buffer assembly 3 includes a clamping frame 301, a buffer spring 302 and a protective cover 303. The clamping frame 301 is installed on the top of the steering main frame 1 through the connecting shaft 2. A buffer spring 302 is provided at one end of the clamping frame 301, and a protective cover 303 is provided on the outside of the buffer spring 302. The clamping frames 301 are symmetrical with each other along the central axis of the steering main frame 1, and the clamping frames 301 are L-shaped, and several clamping frames 301 are connected by the buffer spring 302. The other end of the connecting rod 8 is connected to the steering main frame 1 through the clamping frame 301 bearing.

[0026] The above-mentioned buffer assembly 3 is used to resist vibration and provide buffer protection for the steering wheel 7 on the vibrating side, so that the hub vibration pressure can be effectively relieved on the basis of the rotation of the steering wheel 7. At the same time, this position can be disassembled for easy maintenance and replacement in the future.

[0027] Furthermore, the driving rods 4 are parallel to each other, and the connecting rod 8 is bearing-mounted between the driving rods 4 .

[0028] The above structure can connect the left and right side structures through the driving rod 4.

[0029] Furthermore, the interior of the unilateral vibration damping component 6 includes an inner sleeve 601, a steel ball 602, an outer cylinder 603, a threaded rod 604, a steering cylinder 605 and a positioning spring 606. The inner sleeve 601 is mounted on the outer wall of the mounting frame 5, and the steel ball 602 is embedded in the interior of the inner sleeve 601. The steering cylinder 605 is slidably mounted on one side of the inner sleeve 601. The outer wall of the steering cylinder 605 is fixedly connected to the positioning spring 606. The inner side of the steering wheel 7 is fixedly connected to the outer cylinder 603, and the inner side of the mounting frame 5 is provided with a threaded rod 604.

[0030] The above structure reduces the vibration damage of the wheel itself and the overall vibration of the controller body when the single-side vibration damping component 6 is lifted on one side of the steering wheel 7, thereby achieving a shock absorption effect.

[0031] Furthermore, the threaded rod 604 passes through the mounting frame 5 and is threadedly connected to one side of the inner sleeve 601. The steel ball 602 is located between the inner sleeve 601 and the steering cylinder 605, and the steering cylinder 605 rolls along the inner wall groove of the inner sleeve 601. The other end of the positioning spring 606 is fixedly connected to the outer cylinder 603, and a plurality of positioning springs 606 are arranged inside the outer cylinder 603.

[0032] The above structure can install and fix the single-side vibration damping component 6 through the threaded rod 604.

[0033] Working principle: When in use, first, the two sets of bracket structures designed on the left and right sides of the structure can independently resist vibration on both sides of the steering gear. The middle position is connected by the buffer component 3 to resist vibration on the left and right mounting brackets 5. A buffer bracket is formed between the mounting bracket 5, the driving rod 4 and the buffer component 3. When on bumpy roads, the middle buffer component 3 is retracted and extended. The bearing design of the driving rod 4 and the buffer component 3 is used to lift one side of the drive control bracket, which can keep the other side stable, reducing the overall vibration of the controller body, thereby achieving a shock absorption effect;

[0034] Secondly, the separate buffer structure designed for the steering wheel 7 position can buffer the hubs of the steering wheels 7 on both sides separately, reducing damage to the hub positions. At the same time, while the buffer assembly 3 is anti-vibration, the steering wheel 7 on the vibrating side is buffered and protected, so that the hub vibration pressure can be effectively alleviated on the basis of the rotation of the steering wheel 7. At the same time, the steel ball 602 is provided between the steering cylinder 605 and the inner sleeve 601 to maintain the normal operation of the steering wheel 7.

[0035] Finally, the movable threaded rod 604 is separated from the inner sleeve 601, so that one side of the steering wheel 7 can be disassembled for easy maintenance and replacement in the future.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
