TECHNICAL FIELD

[0001] The utility model relates to the field of furniture, especially a swing chassis with reduced noise. BACKGROUND

[0002] With the improvement of people's living standards, the requirement for the comfort of the seat is also higher and higher, and the product in the field of seat is also developed accordingly; the seat nowadays, the sitting and lying dual-purpose function has become the mainstream, and the comfort improvement aiming at the two points is also more mature, and the manufacturer wants to further increase the competitiveness and improve the sitting feeling, so it is necessary to take a different approach, such as opening up a new track in the sitting freedom, that is, the seat capable of swinging left and right.

[0003] However, this kind of seat, because it is difficult to control the force, when the user swings left and right, the swing structure in the chassis is easy to collide and accompanied by noise, thereby reducing the use experience; the long-term collision between parts is also easy to cause damage, thereby affecting the service life; in order to solve these problems, a better swing chassis is urgently needed. SUMMARY

[0004] In order to solve the above technical problems, the utility model provides a swing chassis with reduced noise.

[0005] The technical scheme of the utility model is as follows:

[0007] The buffer is used for buffering the collision generated when the chassis swings left and right, the buffer has an energy absorption effect, thereby absorbing the energy of the collision, reducing the jerk feeling caused by the collision, and the noise is obviously reduced, thereby improving the use experience; and after the collision part of the fixed seat and the swing seat is separated by the buffer, the two can also be prevented from being damaged due to the collision, thereby prolonging the service life.

[0008] As a preferred, the other of the swing seat and the fixed seat is provided with a collision part, the collision part is arranged in the upper and lower interval of the buffer, and the collision part is configured to increase the contact area with the buffer. The collision part is used for increasing the contact area, thereby reducing the pressure when colliding, and further reducing the adverse effects caused by the collision.

[0009] As preferred, there are at least two groups of buffer members, which are respectively arranged on the left and right sides of the rotating shaft, and the number of the impact parts is the same as that of the buffer members. The buffer members can be a single whole member distributed from the left side to the right side of the rotating shaft, but more material is needed, which is relatively wasteful. The two groups of buffer members arranged separately on the left and right sides can save more material, prevent waste, reduce cost, and be more targeted.

[0010] As preferred, the swing seat is an upwardly open shell, the fixed seat is arranged in the swing seat, and an avoiding hole is arranged on the swing seat, and the fixed seat protrudes downward from the swing seat through the avoiding hole; the buffer member is arranged on the swing seat, and the impact part is arranged on the fixed seat.

[0011] As preferred, the swing seat comprises a vertical mounting plate, the rotating shaft is arranged on the fixed seat and the mounting plate, the buffer member is arranged on the lower part of the mounting plate, and the impact part is arranged on the lower end of the fixed seat; the buffer member protrudes from the mounting plate towards the impact part.

[0012] As preferred, the lower end of the mounting plate is provided with a mounting part, the mounting part protrudes towards the fixed seat and is upwardly open to form a slot, a clamping groove is arranged on the mounting part, and the slot and the clamping groove are through; the buffer member comprises a plug-in part and an acting part, and a clamping part is further arranged on the plug-in part, the buffer member is arranged on the mounting part, the plug-in part is arranged in the slot, the clamping part is clamped in the clamping groove, and the acting part is exposed above the mounting part. In this way, the buffer member is stably arranged on the mounting plate.

[0013] As preferred, the fixed seat comprises left and right transverse plates, the rotating shaft is arranged in the transverse plates; the impact part is arranged at the lower end of the transverse plate, and in the front-rear direction, the length of the impact part is greater than the thickness of the transverse plate. The pressure generated when the originally thinner transverse plate collides with the buffer member is greater, and now the impact part replaces the transverse plate to directly collide with the buffer member, the pressure is smaller, and the impact has less influence.

[0014] As preferred, the buffer member is rubber. It is common and low in cost.

[0015] The design starting point, concept and beneficial effects of the utility model with the above technical scheme are as follows:

[0016] The buffer member is used to buffer the impact generated when the chassis swings left and right, the buffer member has an energy absorption effect, thereby absorbing the impact energy, reducing the jerk feeling caused by the impact, and obviously reducing the noise, thereby improving the use experience; and after the impact part of the fixed seat and the swing seat are separated by the buffer member, the parts are prevented from being damaged due to the impact, thereby prolonging the service life.
