In view of the single running mode and poor terrain adaptability of the existing mobile platform, the invention provides the gait-adjustable wheel-track conversion mobile platform with high maneuverability and high trafficability, which can be freely switched between wheel-type and track-type running modes and has the characteristics of simple structure, good reliability, high switching speed and the like.
This patent is in order to realize above-mentioned purpose, and the technical scheme who takes is a wheel-track switching moving platform, including controller, rack, wheel-track switching system, track system, wheeled system, its characterized in that: the controller is fixed at the top of the rack, the wheel-track switching system is fixed above the rack, the wheel type system is installed at the lower end of the wheel-track switching electric push rod, and the track system is installed at the bottom of the rack.
The wheel-track switching system comprises a wheel-track switching electric push rod and a running wheel support, the wheel-track switching electric push rod is installed below a rack top plate, and the running wheel support is fixedly installed at the lower end of the wheel-track switching electric push rod.
The wheel type system comprises a running wheel and a running wheel driving motor, wherein a running wheel support is fixedly arranged at the lower end of the wheel-track switching electric push rod, the running wheel driving motor is arranged at the running wheel support, and the running wheel is arranged on the running wheel driving motor.
The crawler system comprises a crawler, bearing wheels, crawler supporting wheels, a crawler driving motor and crawler driving wheels, wherein the bearing wheels are arranged at the bottom of the rack, the crawler supporting wheels are arranged on the rack, the crawler driving motor is arranged at two sides of the rack, the crawler driving wheels are arranged on the crawler driving motor, and the crawler is wound on the bearing wheels, the crawler supporting wheels and the crawler driving wheels.
Through holes are formed in the center of the running wheel and the side portion of the running wheel support, and the running wheel is connected with an output shaft of a running wheel driving motor through a flat key.
The caterpillar is provided with a hollow groove which is meshed with a tooth-shaped part on the caterpillar driving wheel.
The upper part of the bearing wheel is provided with a vertical long rod and sleeved with a spring, the bottom of the rack is provided with a through hole, and the long rod passes through the through hole and is arranged below the rack by the spring.
The beneficial effect of this patent is: the wheel-track type traveling mechanism can realize free and rapid switching between the wheel and the track, has the advantages of high maneuverability and high trafficability of the wheel-type traveling mechanism and the track-type traveling mechanism, and meets different traveling requirements of various terrains on the mobile platform.

Detailed Description
The patent will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, the wheel-track switching mobile platform comprises a controller 1, a wheel-track switching electric push rod 2, a traveling wheel 3, a track 4, a bearing wheel 5, a track supporting wheel 6, a rack 7, a track driving motor 8, a track driving wheel 9, a traveling wheel driving motor 10 and a traveling wheel support 11.
When the vehicle runs on soft soil such as sand, a crawler system of the mobile platform works, the controller 1 controls the wheel-track switching electric push rod 2 of the wheel-track switching system to retract upwards, the running wheel support 11 fixed at the lower end of the controller drives the running wheels 3 to lift upwards until the running wheels 3 completely leave the ground, the crawler 4 contacts the ground, the crawler driving motors 8 fixed at two sides of the rack 7 rotate, the crawler driving wheels 9 are driven to rotate by flat keys, and the crawler 4 wound on the crawler driving wheels 9 is driven therewith, so that a crawler running mode is realized.
When the crawler system is used for driving, the crawler supporting wheels 6 jack the upper half part of the crawler 4 upwards to ensure that the crawler 4 is in a tensioning state in the driving process, the bearing wheels 5 are arranged on two sides below the rack to press the lower half part of the crawler 4 on the road surface, so that the sufficient contact area between the crawler 4 and the ground is ensured, and the bearing wheels 5 can move up and down to improve the stability of the moving platform when passing through uneven road surfaces.
When the mobile platform runs on the ground with flat ground and hard geology, a wheel type system of the mobile platform works, the controller 1 controls a wheel-track switching electric push rod 2 of the wheel-track switching system to extend downwards, a running wheel support 11 fixed at the lower end of the controller drives a running wheel 3 to descend until the running wheel 3 contacts the ground, a track 4 leaves the ground, a running wheel driving motor 10 rotates to drive the running wheel 3 to rotate through a parallel key, a wheel type running mode is achieved, the extending length of the wheel-track switching electric push rod 2 can be adjusted as required, and the stability of the mobile platform in the running process is guaranteed.
