A direction-changing mobile device

Abstract

The invention discloses a novel direction-changing moving device which comprises a power source, wheel train structures, a connecting plate, a center gear, push rods I, push rods II, limiting rods I and limiting rods II. The connecting plate is of a square structure, and the wheel train structures are mounted on the four corners of the connecting plate correspondingly. The center gear is mounted in the center of the connecting plate and connected with the power source and can be driven by the power source to rotate forwards or reversely; each push rod I is in a T shape and comprises a vertical rod body and a horizontal rod body, wherein a rack is arranged on the middle section of the vertical rod body and engaged with the center gear. One limiting rod I is arranged in the position, between the corresponding horizontal rod body and the corresponding rack I, of the upper section of the corresponding vertical rod body, and the two ends of each horizontal rod body are engaged with the corresponding wheel train structure. Each push rod II is in a long strip shape, the middle of each push rod II is engaged with the center gear, and one limiting rod II is mounted at one end of the corresponding push rod II. The purpose of changing the moving direction is achieved in a mechanical transmission mode, the structure is simple, movement is stable, and reliability is good.

Description

technical field [0001] The present invention relates to the technical field of mobile devices, in particular to a direction-changing mobile device. Background technique [0002] In the prior art direction changing mobile device, in order to make the structure easy to realize the movement and direction changing requirements of the device, the [0003] The mobile device is designed in a multi-motor drive control mode. In order to obtain independent degrees of freedom for each wheel, each wheel is equipped with its corresponding driving motor, and the direction control of the device can be realized by different rotational speeds or steering directions of each driving motor. Although this one-wheel-one-motor-driven design is structurally convenient to realize the function of moving in multiple directions, it has the disadvantages of low stability, complex structure and high cost.

Problems solved by technology

[0003] The mobile device is designed as a multi-motor drive control method. In order to obtain independent degrees of freedom for each wheel, each wheel is equipped with its own corresponding drive motor, and the direction control of the device can be realized through different speeds or steering directions of each drive motor. Although the design of this one-wheel-one-motor drive is structurally convenient to realize the function of moving in multiple directions, it has the disadvantages of low stability, complicated structure and high cost.
