Description

Technical Field

[0001] The utility model relates to the field of regulators, in particular to a seat height regulator. Background Art

[0002] In order to improve the comfort and safety of passengers, automobile seats generally have basic adjustment functions such as height adjustment, front-back adjustment, and backrest adjustment. With the development of the domestic automobile market and the increasing maturity of consumers' understanding of automobiles, their requirements for the adjustment operation quality of automobile seats are getting higher and higher. For example, issues such as whether the operating force is appropriate and whether the feel during operation is comfortable are problems that consumers are more concerned about. Currently, the operating structure of the height regulator used to adjust the height of an automobile seat is that the operating handle bracket is directly connected to the central axis of the height regulator. If the operating handle bracket is short, the operating force is large; if the operating handle bracket is lengthened, although the operating force is reduced, there are problems such as too long a cantilever, poor lateral stiffness, easy lateral swaying and deformation, and a deteriorated operating feel.

[0003] In the existing technology, such as the "operating structure of an automobile seat height regulator" with Chinese patent number CN104118338B, it includes an operating handle bracket connected to the central axis of the height regulator, a lateral support plate welded to the seat frame for supporting the operating handle bracket, and a limit component connected to the lateral support plate and used to limit the rotation stroke and lateral sliding of the operating handle bracket. A kidney-shaped hole with the same arc center as the rotation center of the operating handle bracket is provided on the operating handle bracket, and the limit component is in clearance fit with the kidney-shaped hole, and the operating handle bracket can slide around the limit component through the kidney-shaped hole. This operating structure can increase the lateral stiffness of the operating handle bracket, avoid lateral swaying and deformation due to the lengthening of the operating handle bracket, and improve the operating comfort.

[0025] The hydraulic column 7 is movably sleeved on the top of the lifting plate 5, and the hydraulic column 7 is perpendicular to the support plate 6; by setting the hydraulic column 7, when adjusting the seat angle, starting the hydraulic column 7 enables the hydraulic column 7 to drive the support plate 6 to flip on the top of the lifting plate 5, thus achieving the adjustment effect of the flatness of the support plate 6, that is, achieving the seat angle adjustment effect, thereby avoiding the problem that the seat can only be adjusted up and down due to the limited adjustment direction of the seat adjuster, and further improving the practicality of the seat adjuster.

[0026] The number of the limit rods 9 is two, and the two limit rods 9 are symmetrically distributed with the support plate 6 as the axis of symmetry; by setting the limit rods 9, when adjusting the seat, the limit rods 9 can limit and fix the lifting plate 5, avoiding the problem that the lifting plate 5 rotates during height adjustment, thus improving the stability during seat height adjustment.

[0027] The reinforcing rod 10 is parallel to the lifting plate 5, and the number of the reinforcing rods 10 is three; by setting the reinforcing rods 10, when adjusting the seat height, the reinforcing rods 10 can strengthen the lifting frame 4, that is, improve the load-bearing capacity of the lifting frame 4, that is, improve the load-bearing capacity of the height adjuster, that is, improve the stability during the operation of the height adjuster.

[0028] The top of the sliding ball 11 is in close contact with the bottom of the limit sleeve 2, and the number of the sliding balls 11 is several; by setting the sliding balls 11, when adjusting the seat position, the sliding balls 11 can support the moving limit sleeve 2, thus avoiding the problem that the limit sleeve 2 rubs against the bottom of the inner cavity of the base 1 during load-bearing movement, resulting in a reduction in the smoothness of the limit sleeve 2, and further improving the smoothness during seat position adjustment.

[0029] The lifting mechanism 12 includes a first motor 121. The first motor 121 is fixedly installed on the side of the limit sleeve 2. A first threaded column 122 is fixedly connected to the output shaft of the first motor 121. The first threaded column 122 is threadedly sleeved inside the sliding block 3. By providing the lifting mechanism 12, when the seat height needs to be adjusted, the first motor 121 is started, so that the first motor 121 can drive the sliding block 3 to horizontally move inside the limit sleeve 2 through the first threaded column 122, that is, drive the lifting frame 4 to move up and down, thus achieving the height adjustment effect of the lifting plate 5, and further bringing convenience to the height adjustment of the seat.

An oil delivery pipe 142 is fixedly sleeved at the bottom of the lubrication sleeve 141. By providing the lubrication mechanism 14, when the seat position is adjusted, the oil delivery pipe 142 can evenly apply lubricating oil on the surface of the driving components through the lubrication sleeve 141, thereby improving the lubricity of the driving components, avoiding the problem of serious wear of the driving components during long-term use, and thus improving the service life of the seat height adjuster.

[0032] The working principle of a seat height adjuster provided by the present utility model is as follows:

[0033] Step 1: First, when adjusting the seat angle, start the hydraulic cylinder 7, so that the hydraulic cylinder 7 drives the support plate 6 to flip on the top of the lifting plate 5, thereby achieving the adjustment effect of the flatness of the support plate 6, that is, achieving the seat angle adjustment effect, thus avoiding the problem that the seat can only be adjusted up and down due to the limited adjustment direction of the seat regulator, and further improving the practicality of the seat regulator. When adjusting the seat, the limiting rod 9 limits and fixes the lifting plate 5, so as to avoid the problem of rotation during the height adjustment of the lifting plate 5, thereby improving the stability during the seat height adjustment. When adjusting the seat height, the reinforcing rod 10 strengthens the lifting frame 4, that is, improves the load-bearing capacity of the lifting frame 4, that is, improves the load-bearing capacity of the height regulator, that is, improves the stability during the operation of the height regulator. When adjusting the seat position, the sliding ball 11 supports the limiting sleeve 2 during movement, thus avoiding the problem that the limiting sleeve 2 rubs against the bottom of the inner cavity of the base 1 during load-bearing movement, resulting in a decrease in the fluidity of the limiting sleeve 2, and further improving the fluidity during the seat position adjustment;

[0034] Step 2: When the seat height needs to be adjusted, start the first motor 121, so that the first motor 121 drives the sliding block 3 to move horizontally inside the limiting sleeve 2 through the first threaded column 122, that is, drives the lifting frame 4 to move up and down, thereby achieving the height adjustment effect of the lifting plate 5, and further facilitating the seat height adjustment. When the seat position needs to be adjusted, start the second motor 131, so that the second motor 131 drives the connecting column 8 to move horizontally through the second threaded column 132, that is, drives the limiting sleeve 2 to move horizontally inside the base 1, thereby achieving the position adjustment effect of the support plate 6, and further facilitating the seat position adjustment. When adjusting the seat position, the oil delivery pipe 142 evenly applies lubricating oil to the surface of the driving components through the lubricating sleeve 141, thereby improving the lubricity of the driving components, avoiding the problem of serious wear of the driving components during long-term use, and thus improving the service life of the seat height regulator.
