Embodiment 1

[0029] Such as Figure 1-6 The shown wheel includes a center frame and several pairs of arc hubs; each pair of arc hubs is connected to the center frame; several pairs of arc hubs form a complete hub, and each pair of arc hubs includes the first arc hub 2 and The second arc hub 8; the right end of the first arc hub 2 is connected with the left end of the second arc hub 8 by a hinge; A number of kinematic changing mechanisms that rotate at the hinge to change the kinematics of the wheel.

[0030] The movement form changing mechanism on the center frame rotates the first arc hub and the second arc hub on both sides of the hinge part 6 around the hinge, thereby realizing the shape change of the complete hub, thereby realizing the change of the movement form; the movement form is the movement The shape and condition of the complete hub at the time.

[0031] For example, when the distance between the hinge of the first arc hub and the second arc hub and the center frame was the s...

Embodiment 2

[0036] Such as Figure 1-6The shown wheel includes a center frame and several pairs of arc hubs; each pair of arc hubs is connected to the center frame; several pairs of arc hubs form a complete hub, and each pair of arc hubs includes the first arc hub 2 and The second arc hub 8; the first connecting block 5 on the right-hand side of the first arc hub 2 is connected with the second connecting block 7 on the left end of the second arc hub 8 by a hinge 6; A plurality of movement form changing mechanisms are used to rotate the first arc hub and the second arc hub around the hinge to change the movement form of the wheels. Preferably, when the distance between the hinge portion of the complete hub and the center frame is the farthest, the section of the complete hub is a circular structure; when the distance between the hinge portion of the complete hub and the center frame is the shortest, the cross section of the complete hub is It is a Lello triangle structure.

[0037] In th...

Embodiment 3

[0045] This embodiment is further improved and optimized on the basis of embodiment 2 as follows.

[0046] Such as Figure 1-6 The shown wheel includes a center frame and several pairs of arc hubs; each pair of arc hubs is connected to the center frame; several pairs of arc hubs form a complete hub, and each pair of arc hubs includes the first arc hub 2 and The second arc hub 8; the first connecting block 5 on the right-hand side of the first arc hub 2 is connected with the second connecting block 7 on the left end of the second arc hub 8 by a hinge 6; A plurality of movement form changing mechanisms are used to rotate the first arc hub and the second arc hub around the hinge to change the movement form of the wheel.

[0047] Each movement form changing structure includes: a retractable mechanism, a telescopic mechanism and a power mechanism. Specifically, the retractable mechanism is used to retract the upper end of the first arc hub and the lower end of the second arc hub ...

Abstract

The invention discloses a wheel, which comprises a center frame and several pairs of arc hubs; each pair of arc hubs is connected with the center frame; several pairs of arc hubs together form a complete hub; each pair of arc hubs includes a first arc hub and The second arc hub; one end of the first arc hub and one end of the second arc hub are hinged through a hinge; the center frame is provided with a device for making the first arc hub and the second arc hub rotate around the hinge A plurality of motion shape changing mechanisms for changing the motion shape of the wheels. The invention can realize the movement of the wheel on flat ground and stairs through the transformation of the motion form, and the wheel of the invention can be used on mobile tools such as wheelchairs that need to climb stairs.

Description

technical field [0001] The invention belongs to the technical field of wheels, and in particular relates to a wheel. Background technique [0002] The wheel is a rigid wheel that fixes the inner edge of the tire, supports the tire and bears the load together with the tire. A wheel is a rotating assembly that bears load between the tire and the axle, usually consisting of two main components, the rim and the spokes (GB / T2933-2009). The rim is the part that installs and supports the tire on the wheel, and the spoke is the supporting part on the wheel between the axle and the rim. In addition to the above components, wheels sometimes also include hubs. Tires are usually installed on metal rims, which can support the vehicle body, buffer external impacts, realize contact with the road surface and ensure the driving performance of the vehicle. Wheels are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and l...
