The elastic supporting pieces 2 are circumferentially and sequentially distributed between the hub 1 and the rim 3 at intervals, and the rim 3 has certain bearing rigidity and forms a bearing peripheral surface. The elastic support piece has a rigidity adjustable function so as to adapt to actual function requirements in different application scenes.

It should be understood that the manner of driving (pedal or electric) of the bicycle and the dimensional proportions of the various frame parts are not central to the present application and do not constitute a substantial limitation on the frame claimed in the present application.

As shown in fig. 1, the stressed deformation area of the elastic support member 2 can be formed by coiling the body of the elastic support member, and the elastic support member can have elastic shock absorbing and impact resisting capabilities in the running process when the elasticity of the elastic support member reaches a certain threshold value, similar to a traversing spring structure. Here, the outer end structures of the elastic supports 2 of the driving wheel (rear wheel in this view) and the driven wheel are directed in a clockwise direction so as to facilitate the release of the stored elastic deformation energy during the movement, and to assist the counterclockwise rotation of the whole wheel or rim. In other embodiments, the elastic support 2 may also form a stress deformation region (not shown in the figures) by bending the body around. Here, the deformed bearing structure of the elastic support is not the core point of the present application, and therefore will not be described herein.

In order to adjust the rigidity of the elastic support 2, in the present embodiment, a rubber member 4 may be interposed in a swivel hole 2-1 formed by swiveling a body of the elastic support 2.

In a specific implementation, cover plates 5 are respectively arranged on two sides of the rubber piece 4, the two cover plates 5 can be matched through first screws 6 inserted into the rubber piece 4, the distance between the two cover plates 5 can be adjusted through the first screws 6, and then the deformation of the rubber piece 4 can be adjusted through the clamping force applied to the two cover plates 5; specifically, the first screw 6 passes through a through hole on one cover plate 5 and is in threaded fit with a threaded hole on the other cover plate 5, and as the first screw 6 locks the two cover plates 5, the two cover plates can correspondingly squeeze the rubber member 4 and radially expand in the rotary hole 2-1, and can be adjusted according to the use requirement of an actual application scene, so that the elastic support member 2 with corresponding rigidity is obtained. Has better adaptability.

In other embodiments, other configurations of the rubber member 4 as a compressibly deformable member may be used, such as, but not limited to, a micro-balloon structure, which also expands radially inside the swivel hole 2-1 when both sides are compressed.

In order to further increase the adjustability of the rigidity, the body section of the elastic support 2 extending from the swivel aperture can be fitted with a filler 7 as required. Referring to fig. 3 and 4, fig. 3 is a sectional view b-b of fig. 1, and fig. 4 is a schematic diagram illustrating an assembly relationship of the filling member 7 on the elastic support member 2 according to the present embodiment.

In the figure, the two sides of the body section of the elastic support piece 2 extending from the rotation hole are provided with accommodating grooves 2-2, the section of the body section is I-shaped, and each accommodating groove 2-2 is provided with a gradually-expanding groove wall from inside to outside; accordingly, the side surfaces of the packing 7 are configured as inclined surfaces adapted to the groove walls of the receiving groove 2-2, and the two packing 7 are at least partially built into the corresponding receiving groove 2-2 and connected by the second screw 8 to adjust the interval between the two packing. Based on the difference of the screwing degree of the second screw 8, corresponding compressive prestress matching the gradient is formed so as to adjust and obtain different damping, the body rigidity of the elastic support 2 can be quickly adjusted and improved, and the elastic support is suitable for application scenes with large adaptation difference of the vehicle body, such as but not limited to large changes of load and/or road conditions, and the like. In addition, the corresponding adjustment operation can be performed at any time according to the needs of users, and the method has good operability.

It will be appreciated that the front wheel 10-1 as the driven wheel, and the rear wheel 10-2 as the driven wheel, may be selected according to specific functional needs.

Wherein, for the front wheel 10-1 as the driven wheel, two different action working modes can be adopted.

In one implementation, the hub 1 is sleeved on the wheel shaft 20a with rolling capability, the inner end part of the elastic support 2 is fixed on the hub 1 and can rotate around the axle center, and the rim 3 is sleeved on the outer end part of the elastic support 2 and is not fixedly connected with the outer end part of the elastic support 2.

During the movement of the driven wheel, the rotational angular speeds of the rim 3 and the elastic support 2 may be the same or different based on the friction of the rim 3 against the elastic support 2.

Referring to fig. 6, an enlarged view of portion II of fig. 1 is shown, and a contact-type engagement structure between the rim 3 and the elastic support member 2 is shown. As shown in fig. 6, the outer end 2-3 of the resilient support 2 is in contact engagement with the inner surface of the rim 3, such as, but not limited to, the bottom of the mounting groove 3-1, with a relatively high coefficient of friction when rotated relative to each other.

Referring to fig. 7, another contact-type engagement structure between the rim 3 and the resilient support 2 is shown. As shown in fig. 7, a wear-resistant sheet layer 2-5 is disposed between the outer end 2-3 of the elastic support member 2 and the rim 3 to reduce friction loss between the outer end 2-3 of the elastic support member 2 and the inner surface of the rim 3, so that on one hand, work efficiency can be improved, and on the other hand, material cost of the rim 3 and the elastic support member 2 can be reduced, and good actuation performance can be achieved.

Referring to fig. 8 and 9, fig. 8 is a schematic diagram illustrating another assembly relationship between the hub 1b and the axle 20b, and fig. 9 is an enlarged schematic diagram of a portion III of fig. 1.

Here, the circumferential rotation limitation formed between the hub 1 and the axle 20b is illustrated in fig. 8 by taking a square fit section as an example. As shown in fig. 9, which shows a schematic view of still another contact-type engagement structure between the rim and the elastic support member, the roller 2-4 is disposed on the outer end 2-3 of the elastic support member 2, and the elastic support member 2 can be adapted to roll along the inner surface of the rim 3 by the roller 2-4, for example, but not limited to, to roll along the bottom of the mounting groove 3-1, and only the rim rotates when the vehicle body moves, and the friction coefficient is relatively small.

The rear wheel 10-2 serving as the drive wheel may be formed by separately processing and then assembling the elastic support 2 and the rim 3, or may be formed integrally.

For the driving wheel assembled by split processing, in order to avoid the impact of the transmission efficiency caused by different angular speeds of the rim 3 and the elastic support member 2 during the rotation of the wheel, a stop limit pair may be further disposed between the rim 3 and the elastic support member 2, please refer to fig. 10, which is an enlarged schematic view of the IV portion in fig. 1.

As shown in the figure, corresponding to the outer end 2-3 of the elastic support 2, two circumferential stop portions 3-3 formed by extending radially are provided on the inner wall surface of the rim 3, and the two circumferential stop portions 3-3 are disposed at intervals in the circumferential direction and respectively abut against two sides of the outer end 2-3 of the elastic support 2 to form a stop limit pair capable of limiting relative rotation in the circumferential direction.

Of course, for the integrally formed driving wheel, please refer to fig. 11 and 12 together, wherein fig. 11 is an enlarged schematic view of the V portion of fig. 1, and fig. 12 is a sectional view d-d of fig. 1. The cross-section shows an integrated implementation, in which the rim 3 is shown integrated with the elastic support 2.

It can be understood that the wheel rim 3 and the elastic support 2 are integrally formed, and the wheel rim 3 rotates synchronously with the elastic support 2, and can be applied to driven wheels according to design requirements.

In addition, in the structural implementation manner of split processing and assembling of the rim 3 and the elastic support 2, the rim 3 can be designed to synchronously rotate along with the elastic support 2, and can also be designed to have relative rotation between the two.
