The embodiment provides a shock-absorbing frame 100 which can be used in a power-assisted bicycle, a bicycle and other mobility tools.

As shown in FIGS. 1 and 3, the shock absorbing frame 100 may include a frame body 10, a connector bracket assembly 20, and a shock absorber 30.

The frame body 10 can serve as a carrier in a shock absorbing frame 100, and the bracket assembly 20 and the shock absorber 30 can be mounted attached to the frame body 10. In some embodiments, the frame body 10 may include a support beam 11 and a cross beam 12 connected. The cross member 12 can be used to support a seat or the like of a walk-substituting tool. It will be appreciated that only a portion of the structure of the beam 12 is shown. In some embodiments, the support beam 11 and the cross beam 12 may be a unitary structure.

In other embodiments, the support beam 11 and the cross beam 12 may be connected by welding, screws, or the like.

Referring also to fig. 7, the support beam 11 may be connected to one end of the cross beam 12. It will be appreciated that the support beam 11 may be used as a vertical beam and that the support beam 11 may be arranged inclined relative to the cross beam 12. When the shock absorbing frame 100 is applied to a ride instead of walk, the support beam 11 may be located at an end of the cross member 12 near a rear wheel in the ride instead of walk. In addition, the end of the support beam 11 remote from the cross beam 12 can be used to connect the bottom bracket mechanism 200 in the walk aid.

Referring again to FIG. 4, the support beam 11 may include a first end 1101 and a second end 1102. Wherein the second end 1102 may be connected to the beam 12 and the first end 1101 may be disposed away from the beam 12. Accordingly, first end 1101 may be used to connect bottom bracket mechanism 200.

As shown in fig. 1, 4 and 5, the connector housing assembly 20 may include a first connector end 201 and a second connector end 202. The first connection end 201 is rotatably connected to the first end 1101 of the support beam 11, i.e., the connection frame assembly 20 is capable of rotating relative to the support beam 11. The second connecting end 202 can be used for connecting the rear wheel of the transportation tool, i.e. the connecting frame assembly 20 can be used for connecting the frame body 10 and the rear wheel.

Referring also to FIG. 2, in some embodiments, one end of the shock absorber 30 can be hinged to the support beam 11. The connection position of the shock absorber 30 to the support beam 11 can be referred to as a connection point O ₁ . In the embodiment, the connection point O ₁ May be located between the first end 1101 and the second end 1102.

The other end of the shock absorber 30 can be hingedly connected to the connector frame assembly 20. Correspondingly, the connection position of the shock absorber 30 and the connecting frame assembly 20 can be designated as the connection point O ₂ . Connection point O ₂ May be located between the first connection end 201 and the second connection end 202.

When the shock-absorbing frame 100 is applied to a walking tool, the shock-absorbing frame 100 can move towards the direction close to the ground under the action of pressure when the shock-absorbing frame 100 bears the load, and meanwhile, the rear wheel in the walking tool can elastically deform. Under the elastic force of the rear wheel, the second connecting end 202 of the connecting bracket assembly 20 can be pushed to rotate around the first connecting end 201, even if the connecting bracket assembly 20 rotates relative to the support beam 11, and the shock absorber 30 is driven to compress, so that the shock absorber 30 stores a certain elastic potential energy. When the user encounters a bumpy road section, the shock absorber 30 can release and store elastic potential energy better, the shock absorption effect is achieved, the bumpy feeling of the user is reduced, and the user experience is improved.

It can be understood that the angle between the connecting frame assembly 20 and the support beam 11 can be adjusted adaptively according to the weight of the user, so as to provide effective shock-absorbing effect for users with different weights. Therefore, more comfortable riding experience can be provided for users with different weights, and the user experience is improved.

The accommodating cavity 401 may be used to mount the middle shaft mechanism 200 in the walk-substituting tool, that is, the middle shaft mechanism 200 may be disposed in the shaft sleeve 40, and the shaft sleeve 40 and the middle shaft mechanism 200 are coaxially disposed.

Referring to fig. 4 and 5, the first end 1101 of the support beam 11 is rotatably mounted on the outer side of the shaft sleeve 40, i.e., the side of the shaft sleeve 40 away from the accommodating cavity 401. Correspondingly, the first end 1101 of the support beam 11 may be formed with a mounting hole 111 for the shaft sleeve 40 to pass through. The support beam 11 may be installed at a middle position of the shaft sleeve 40 in the axial direction of the shaft sleeve 40.

In the illustrated embodiment, shock absorbing frame 100 further includes a lubrication member 50. The lubricating member 50 may be installed in the installation hole 111 between the support beam 11 and the bushing 40. The lubricating member 50 is used to smoothly rotate between the bearing beam 11 and the bushing 40. In some embodiments, the lubrication 50 may be a bearing. Wherein, the inner ring of the bearing can be fixedly sleeved outside the shaft sleeve 40. The outer ring of the bearing can be fixedly mounted relative to the inner wall of the mounting hole 111, i.e. the outer ring of the bearing is fixedly connected to the support beam 11. Accordingly, the relative rotation between the support beam 11 and the bushing 40 can be ensured smoothly by the lubricating material 50.

In an embodiment, the shock absorbing frame 100 may include two bearings. Along the axial direction of the mounting hole 111, two bearings can be separately arranged at two ends of the mounting hole 111 to ensure the balance of two sides of the support beam 11 and reduce the occurrence of the problems of inclination, blockage and the like.

Of course, in other embodiments, one, three, etc. bearings may be disposed between the support beam 11 and the bushing 40.

In other embodiments, the lubricating element 50 may be a grease or the like. Grease may be filled in the fitting gap between the bearing beam 11 and the sleeve 40 to provide lubrication and ensure smooth rotation between the bearing beam 11 and the sleeve 40.

In other embodiments, the lubricating member 50 may be a ball bearing or the like. Correspondingly, rolling grooves can be formed in the inner wall of the mounting hole 111 and the outer side wall of the shaft sleeve 40, and the rolling grooves in the inner wall of the mounting hole 111 can be opposite to the rolling grooves in the outer side wall of the shaft sleeve 40. The balls are rollably mounted in the rolling grooves to provide lubrication.

Illustratively, an end of the first connecting frame 21 near the first connecting end 201 and an end of the second connecting frame 22 near the first connecting end 201 can be fixedly mounted on the shaft sleeve 40 by riveting, welding, screwing, or the like.

In some embodiments, the first connecting frame 21 and the second connecting frame 22 can be fixedly connected by screws or the like near one end of the first connecting end 201, so as to improve the structural stability of the connecting frame assembly 20.

The end of the first link frame 21 adjacent to the second link end 202 and the end of the second link frame 22 adjacent to the second link end 202 may be opened in directions away from each other. The end of the first link frame 21 adjacent the second link end 202 and the end of the second link frame 22 adjacent the second link end 202 may be used to connect the rear wheels of the mobility aid, i.e. the rear wheels may be mounted between the first link frame 21 and the second link frame 22.
