Detailed Description

The application provides a damper of a seat of a lawn mower, which is suitable for riding lawn mowers. The mower seat mainly comprises a mower frame 1 and a seat frame 2, wherein a seat 3 is arranged on the seat frame 2, the seat frame 2 comprises a first frame 21 and a second frame 22, and the first frame 21 is transversely arranged at the rear end of the seat from left to right; the second frame 22 is disposed at both sides and the front side of the seat. The rear end of the movable frame 4 is hinged with the rear end of the second frame 22 of the seat frame 2 through a long pin shaft 16, the front end of the movable frame 4 is hinged with the mower frame 1, specifically, two longitudinally extending mounting pieces 5 are arranged on a cross rod of the mower frame 1, and the front end of the movable frame 4 is arranged between the two mounting pieces 5 and is in running fit through a bolt.

A first spring group 6 is provided between the front end of the movable frame 4 and the seat frame 2 (i.e., the front side of the second frame 22); the first spring group 6 comprises two longitudinally mounted springs which are respectively arranged at the left side and the right side; a second spring group 7 is arranged between the rear end of the seat frame 2 and the mower frame 1, and the second spring group 7 also comprises two springs which are longitudinally arranged, in particular two support beams 1a which extend forwards and backwards and are respectively arranged on the mower frame 1. Therefore, the front end and the rear end of the mower seat can move and extrude the spring, and the effect of damping and buffering is provided by means of the elastic restoring force of the spring.

In order to limit the movable fit between the movable frame 4 and the seat frame 2, the maximum movable distance between the movable frame 4 and the seat frame 2 is limited. A limiting mechanism 8 is arranged between the movable frame 4 and the seat frame 2. Specifically, stop gear 8 includes: a stopper pin 81 provided at a side wall of the seat frame 2 and extending laterally; and a limit ring 82 fixed on the side wall of the movable frame 4 and sleeved on the limit pin 81. In order to increase the compression range, the side wall of the movable frame 4 is further provided with an escape groove 83 which is matched with the contour of the inner hole of the limit ring 82. Thus, the stopper pin 81 can move within the range of the escape groove 83 and the stopper ring 82.

In order to reduce the assembly space as much as possible, the structure is made more compact. Referring to fig. 2, the side wall 23 of the seat frame 2 is movable relative to the side wall 41 of the movable frame 4, and is at least partially covered by the side wall 41 of the movable frame 4.

The application further provides a wheel damping structure of the riding mower, and the wheel damping structure is arranged on a cross beam 1b at the front end of the mower frame 1 and is mainly used for damping the front wheels of a vehicle. Also, the wheel-damping structure of the present embodiment can be applied to the rear wheel of the lawn mower according to different arrangements, which is not technically difficult for those skilled in the art.

For the present embodiment, the method specifically includes:

the connecting sleeves 9 are welded at the left end and the right end of the cross beam 1b and are obliquely arranged, and the distance between the upper ends of the two connecting sleeves 9 which are arranged in a separated mode is smaller than that between the lower ends of the two connecting sleeves. Meanwhile, hollow plungers 10 are further mounted at the upper end and the lower end of the connecting sleeve 9.

The wheel shafts 11 and 11 are of a generally L-shaped structure and comprise longitudinal sections 111 and transverse sections 112, an included angle formed by the longitudinal sections 111 and the transverse sections 112 is larger than 90 degrees, so that the included angle is matched with the connecting sleeves 9 which are obliquely arranged, and the design that the upper portions are narrow and the lower portions are wide can provide an avoiding space for mounting a vehicle. Specifically, the longitudinal section 111 of the wheel shaft 11 is movably inserted into the hollow plunger 10 in the connecting sleeve 9; the transverse section 112 of the wheel axle 11 is then used for mounting the front wheels.

One end of the positioning piece 12 is sleeved on the longitudinal section 111 of the wheel shaft 11, the other end of the positioning piece 12 is hung on the mower frame 1 through a pin shaft 13, and a locking nut 14 is arranged at the lower end of the pin shaft 13, namely the lower end face of the positioning piece 12, so that the positioning piece 12 is prevented from being separated, and the positioning piece 12 can longitudinally move on the pin shaft 13 so as to change the distance between the positioning piece 12 and the connecting sleeve 9; a first limiting piece 17 is fixed at the upper end of the wheel shaft 11, and a second limiting piece 18 is arranged on the connecting sleeve 9 and the damping spring 15.

In order to realize shock absorption, the shock absorption device further comprises a shock absorption spring 15 which is sleeved on the longitudinal section 111 of the wheel shaft 11, is arranged between the connecting sleeve 9 and the positioning piece 12 and is used for driving the positioning piece 12 and the wheel shaft 11 to return.

Therefore, a front wheel damping system of the vehicle is formed, and the vehicle runs more stably and comfortably.

The above description is only a preferred embodiment of the present application, and is not intended to limit the present application in any way, and simple modifications, equivalent changes and modifications may be made without departing from the technical scope of the present application.
