The utility model provides a seat angle adjusting device and a seat using the same, wherein, referring to fig. 1 to 7, the seat angle adjusting device comprises an adjusting base 100, a connecting part 200, an elastic buffer body 300 and a limiting protrusion 400; the adjusting base 100 is hollow and has a ring-shaped first inner connecting surface 101, the ring-shaped first inner connecting surface encloses to form a cylindrical cavity, and the adjusting base 100 is used for connecting and supporting a seat surface of a seat; the connecting part 200 is used for connecting a supporting column 500 of a seat and the adjusting base 100, the connecting part 200 is annular and has a second inner connecting surface 201 and an outer connecting surface 202, and the second inner connecting surface 201 is used for connecting the supporting column 500; the elastic buffer body 300 is annular and is fittingly embedded between the first inner connecting surface 101 and the outer connecting surface 202 with the first inner connecting surface 101 and the outer connecting surface 202; the limiting protrusion 400 is embedded in the elastic buffer body 300 to reduce the maximum deformation of the elastic buffer body 300.
The adjustment of the seat surface inclination angle adopts a dynamic adjustment mode and needs to have an elastic recovery function. The utility model provides a seat angle adjusting device adopts the elastic buffer body 300 as the part that provides elastic restoring force. When the same amount of force is applied, the larger the thickness of the elastic buffer 300, the larger the amount of deformation thereof, the larger the change in the seat surface angle, and the easier the adjustment of the seat surface angle.
In order to realize the difference of the inclination angle adjustment of the seat in different directions, in a specific embodiment, the cylindrical cavity is in an elliptic cylinder shape, the major axis direction of the ellipse is the front-back swing direction of the seat, and the minor axis direction of the ellipse is the left-right swing direction of the seat, so that the effect that the maximum inclination angle of the front-back swing of the seat is larger than the maximum inclination angle of the left-right swing of the seat is achieved.
The utility model provides a seat angle adjusting device is applicable to the seat of single support column, the support column 500 of seat is connected to connecting portion 200, adjust the seat face that seat is connected to base 100, set up the elastic buffer body 300 between rigid regulation base 100 and rigid connecting portion 200, when the seat face receives unbalanced top-down's power, the seat face can take place to deflect, and the elastic buffer body 300 can receive the pressure of side direction because of the deflection of seat face, therefore takes place elastic deformation to produce elastic restoring force.
The elastic buffer body 300 is preferably made of rubber and has a thickness of 5mm to 25 mm. After the elastic buffer 300 is subjected to multiple times of deformation recovery, especially multiple times of deformation recovery with large deformation amount, the elastic deformation capability of the elastic buffer becomes weak, so that the elastic buffer can not recover normally after being deformed. In order to prolong the reduction of the elastic deformation capacity of the elastic buffering body 300, increase the times of the elastic deformation and prolong the service life of the elastic buffering body, the utility model discloses a limiting protrusion 400 arranged along the connecting part 200 or along the circumference of the adjusting base 100 is arranged between the connecting part 200 and the adjusting base 100, the limiting protrusion 400 is embedded in an avoiding position 301 in the elastic buffering body 300, and the avoiding position 301 can be an avoiding hole or an avoiding groove; when the elastic buffering body 300 is deformed laterally, the limiting protrusion 400 can reduce the maximum deformation of the soft elastic buffering body 300 under the condition of ensuring the whole thickness of the elastic buffering body 300, thereby reducing the damage of the elastic buffering body 300 and prolonging the service life of the elastic buffering body. The limiting protrusion 400 may be an annular protrusion or a plurality of tooth-shaped protrusions uniformly arranged in an annular shape.

In this embodiment, the limiting effect of the limiting protrusion 400 on the front-back swing of the seat is smaller than the limiting effect on the left-right swing of the seat, so that the maximum inclination angle of the seat in the front-back direction is larger than the maximum inclination angle of the seat in the left-right direction. In other embodiments, the protruding height of the tooth-like protrusions in the first direction is smaller than the protruding height of the tooth-like protrusions in the second direction, or the pitch of the tooth-like protrusions in the first direction is larger than the pitch of the tooth-like protrusions in the second direction.
The place that the elastic buffer body 300 takes place the deformation volume when the seat face angle changes is its upper end and lower extreme, consequently, in the utility model discloses in, spacing protruding 400 sets up the upper end and/or the lower extreme at the column cavity, just spacing protruding 400 is the metalwork.
In one embodiment, the limiting protrusion 400 is disposed on the first inner connecting surface 101 of the adjusting base 100, and the protruding height of the limiting protrusion 400 is smaller than the distance between the connecting portion 200 and the adjusting base 100. The circumferentially arranged stopper protrusions 400 are inserted from the outer side surface of the elastic buffer body 300.
In another embodiment, the limiting protrusion 400 is disposed on the outer connecting surface 202 of the connecting portion 200, and the protruding height of the limiting protrusion 400 is smaller than the distance between the connecting portion 200 and the adjusting base 100. The circumferentially arranged limit protrusions 400 are embedded from the inner side surface of the elastic buffer body 300.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
