Multi-functional wheel structure with variable wheel diameter

Abstract

The invention discloses a multi-functional wheel structure with the variable wheel diameter. The multi-function wheel structure comprises a motor, a small-spoke limiting guiding plate, small spokes, driving plates provided with threads, large spokes and a large-spoke limiting guiding plate. The driving plates are fixedly arranged on a rotating shaft of the motor in a sleeving mode. The small-spokelimiting guiding plate and the large-spoke limiting guiding plate keep static relative to a stator of the motor. The small spokes, the driving plates and the large spokes are arranged between the small-spoke limiting guiding plate and the large-spoke limiting guiding plate in sequence and axially limited. The small spokes and the large spokes are each composed of fan blocks arranged annular and capable of moving in the radial direction. All the fan blocks are provided with threads engaged with the threads of the driving plates. According to the multi-function wheel structure with the variablewheel diameter, the ground height of a chassis can be changed by adjusting the diameter of a wheel, the outer rim of the wheel can also be changed into a non-circular circle, the surface adaptabilityof the wheel is good, and the multi-function wheel structure climbs steps or crosses gullies more easily and can adapt to operation under various terrain conditions.

Description

technical field [0001] The invention belongs to the field of wheel structure design, in particular to a wheel structure with multifunctional variable wheel diameter. Background technique [0002] Wheeled mobile mechanisms are widely used in today's society. The wheeled mobile chassis has a simple structure, high operating efficiency and good stability. However, in the existing wheel structure, the diameter of the wheels is fixed, and the size of the wheels cannot be adjusted, so that there are the following defects: [0003] 1) The ground adaptability of the wheels is poor and cannot adapt to operation under various terrain conditions; [0004] 2) Most of the outer edges of the wheels are a full circle, making it difficult to climb up obstacles such as stairs and bosses; [0005] 3) When the diameter of the wheel is fixed, the height of the connected chassis from the ground is also fixed. [0006] How to improve the obstacle-surmounting performance and ground adaptability...
