Technical Field

The invention relates to a balance car, in particular to a Mecanum wheel type four-wheel balance car.

Background

Balance car in the existing market is difficult for keeping away the barrier when meetting obstacles such as some big stones, turns to slowly to most balance cars can only the back-and-forth movement, and unable lateral shifting and most balance car shock attenuation effect are poor, can perk certain angle when one side wheel crosses the barrier, seriously influences the balanced sense.

Disclosure of Invention

The invention aims to provide a Mecanum wheel type four-wheel balance vehicle to solve the technical problems in the background technology.

In order to achieve the purpose, the Mecanum wheel type four-wheel balance car comprises a car body, a steering operation handle and a walking mechanism, wherein the steering operation handle is connected with the car body through a steering support column; the traveling mechanism is connected with the vehicle body through a damping device.

Furthermore, the damping device comprises a shell, a supporting guide rod, a linear bearing sliding block, a spring and a vehicle body side steel plate, wherein the shell is fixed on two sides of the vehicle body, the supporting guide rod is fixedly arranged in the shell, and the spring and the linear bearing damping sliding block are sequentially sleeved on the supporting guide rod from high to low; the automobile body side steel plate can slide up and down along the square hole under the driving of the linear bearing slider.

Further, running gear includes mecanum wheel and installing support, the installing support includes V-arrangement steel side pipe and slewing bearing, mecanum wheel is installed the tip of V-arrangement steel side pipe, slewing bearing one side with V-arrangement steel side pipe fixed connection, one end fixed mounting be in on the automobile body side steel sheet.

Furthermore, an ultrasonic ranging sensor and a switch are arranged in front of the vehicle body.

The invention has the beneficial effects that: the obstacle crossing capability of the balance car is greatly improved by arranging the four Mecanum wheels on the two sides of the car body; damping device and mecanum wheel cooperation make the balance car have more balanced walking experience when the road surface of unevenness.

Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1, a mecanum wheel type four-wheel balance car comprises a car body 3, a steering operation handle 1 and a walking mechanism, wherein the steering operation handle 1 is connected with the car body 3 through a steering support column 2; the traveling mechanism is connected with the vehicle body 3 through a damping device. Wherein, the car body 3 is provided with a pedal position, and the steering operation handle 1 is used for holding by hands.

As shown in fig. 2, the damping device includes a housing 5, a spring 14, a linear bearing slider 15, and a support guide rod 16, the housing is fixed on two sides of the vehicle body 3, the support guide rod 16 is fixedly disposed in the housing, and the spring 14 and the linear bearing slider 15 are sequentially sleeved on the support guide rod 16 from high to low; the square hole has been seted up on the casing 5, and the casing 5 outside is provided with automobile body side steel sheet 11, and linear bearing slider 15 sees through the square hole and is connected with automobile body side steel sheet 11, and automobile body side steel sheet 11 can slide from top to bottom along the square hole under the drive of linear bearing slider 15. Two Mecanum wheels 8 are respectively arranged on one side of two sides of the vehicle body 3, the two Mecanum wheels 8 are connected through a V-shaped steel square pipe 9, so that the obstacle crossing is advantageous, and the turntable bearing 10 is arranged on the damping device, so that the obstacle crossing is stable, and the hard contact phenomenon cannot occur. In addition, a drive motor 6 is arranged on the travelling mechanism, and the drive motor 6 is connected to the mecanum wheel 8 through a coupling shaft.

As shown in fig. 1, the front surface of the vehicle body 3 is also provided with an ultrasonic distance measuring sensor 12 and a switch 13. The ultrasonic ranging sensor 12 can detect the road condition ahead, and if there is a high obstacle, the mecanum wheel can be controlled to move transversely so as to avoid the obstacle.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes which can be made within the knowledge of those skilled in the art without departing from the gist of the present invention are within the scope of the claims of the present invention.
