Embodiment 1

[0032] Such as Figure 1~4 As shown, a flexible shock-absorbing intelligent trolley wheel module of the present invention includes a 匚-shaped vehicle frame 1 and wheels 2, and also includes a shock-absorbing device 3 and a fixing seat 4, a wheel rolling drive mechanism 5 and a wheel steering drive mechanism 6, The wheel 2 adopts a rubber tire, and the middle part of the rubber tire is fixedly equipped with a hub 9 with a shaft, and a fixed shaft is installed in the middle part of one side of the hub 9 with a shaft. The middle part of the fixed shaft is provided with a triangular hole 9a. Type wheel support 7-1 and sliding shaft 7-2, the left and right side panels of inverted U-shaped wheel support 7-1 are symmetrically installed with wheel shaft installation bearing 7-3, by the belt shaft hub 9 and wheel shaft installation bearing 7-3 Cooperate with the connection, the wheel 2 is rotatably installed on the inverted U-shaped wheel bracket 7-1, the sliding shaft 7-2 is fixed on ...

Embodiment 2

[0036] The difference between this embodiment and embodiment 1 is that, as Figure 5 As shown, the two fixing seats 4 are installed on the sides of two adjacent openings of the 匚-shaped vehicle frame 1. This independent flexible shock-absorbing smart car wheel is used to insert and fix the two ends of the connector 8 on different flexible shock-absorbing smart cars. In the fixed seat 4 of the wheel, it can be spliced ​​and assembled into such as Figure 6 The wheel module of the four-wheeled flexible shock-absorbing smart car shown.

[0037] Such as Figure 14 As shown, the motor controller can realize the four-wheel straight running, four-wheel backward, and in-situ turning of the four-wheel flexible shock-absorbing smart car wheel module by controlling each wheel 2 to rotate accordingly (differential speed, two wheels on the left) 2 forward rotation, two wheels on the right side 2 reverse rotation), in-situ rotation (front wheel, four wheels 2 circular rotation), lateral t...

Embodiment 3

[0039] The difference between this embodiment and embodiment 1 is that, as Figure 7 As shown, two fixing seats 4 are installed on two opposite sides of the U-shaped vehicle frame 1 respectively, and one of them is installed on the outer wall of the riser surface of the U-shaped vehicle frame 1 .

Abstract

The invention discloses a wheel module of a flexible shock-absorbing smart trolley. The wheels are rotatably mounted on an inverted U-shaped wheel bracket with axles, and are located directly below the U-shaped frame. The wheel rolling drive mechanism is provided with inverted U-shaped axle wheels. The bracket is connected with the wheel drive. The wheel steering drive mechanism drives the wheel steering through the inverted U-shaped wheel bracket with axle. The wheel steering drive mechanism is installed on the 匚-shaped frame. Up and down sliding connection, the shock absorber is installed on the top shaft of the inverted U-shaped wheel bracket with axle, and is located between the 匚-shaped frame and the inverted U-shaped wheel bracket with axle, and the fixing seat is fixed on the side of the 匚-shaped frame for matching The connecting parts are spliced ​​to assemble the wheel module of the flexible shock-absorbing smart car. The invention has a simple and compact structure and has the function of shock absorption. At the same time, the wheels can roll and turn, and the fixed seat can be assembled with the connecting parts to assemble the wheel module of the multi-wheel flexible shock-absorbing intelligent trolley. The product has high flexibility and wide application range.

Description

technical field [0001] The invention belongs to the technical field of smart cars, and in particular relates to a flexible shock-absorbing smart car wheel module. Background technique [0002] Since the smart car can automatically operate in an environment according to the preset mode, it can be used in shooting, transportation and other fields, and is widely loved by the public. However, the existing AGV cars and other smart cars generally have the following technical shortcomings: 1. No shock absorption, easy to cause damage to objects during transportation; 2. The size of the car is not adjustable, and the scope of application is limited. Therefore, in order to expand the application range of the smart car and improve its practicability, it is urgent to design a smart car with a shock-absorbing function and an adjustable size. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a size-adjustable...
