Problems solved by technology

[0003] 1) The steering mechanism of traditional vehicles has a complex structure, high cost, and heavy weight of the vehicle itself
In actual use, due to the heavy weight of the vehicle body, it is difficult to go straight or turn, which wastes power and cannot achieve real-time control
Moreover, the steering control process is complicated, and the steering cannot be realized simply through the wheel speed difference on both sides.
[0004] 2) Most of the traditional vehicles are a single platform, and it is difficult to cascade mobile platforms. When used in industrial and other fields, a single mobile platform is limited to transport goods, and vehicles and platforms need to be transported back and forth between the destination and the cargo location in order to achieve the purpose , low work efficiency

Embodiment approach 1

[0032] The invention discloses a mobile platform, which comprises a chassis 2 and a drive bridge 1, wherein the number of the two chassis is N, and the number of one drive bridge is N+1, where N is a positive integer greater than or equal to 1. The drive axle 1 includes a drive axle support 101 and wheels rotatably connected to both ends of the drive axle support 101, chassis hinge connectors 201 are arranged on both sides of the chassis 2, N chassis 2 and N+1 drive axles 1 are arranged at intervals in sequence, and the drive axle 1 can rotate relative to the chassis 2, and the drive axle bracket 101 is hinged to the chassis hinge connection part 201 through a coaxial hinge. The angle of the wheel 3 relative to the drive axle support 101 is constant, and the wheel 3 is provided with a wheel driving mechanism to drive it to rotate.

[0033]In this embodiment, N=1, so the mobile platform is a four-wheel trolley structure. In this embodiment, the drive axle support 101 and the ch...

Embodiment approach 2

[0044] The difference between this embodiment and Embodiment 1 is: see the attached image 3 , the coaxial hinge includes a hinge shaft three 111 and a hinge connection part three 112 and a hinge connection part four 113 arranged symmetrically in the center, the hinge shaft three 111 runs through the drive axle support 101, and is fixed on the drive axle support 101 by a fixing key 106; the hinge Connecting part 3 112 and hinge connecting part 4 113 are hollow inside, and the two are interspersed and arranged on the upper side and the lower side of the drive axle bracket 101. 3 111, see attached image 3 , Bearings 108 are provided with 4 pieces, respectively arranged on the upper and lower side walls of hinge connector three 112 and hinge connector four 113 and are rotationally connected with hinge shaft three 111 . The other ends of the hinge connector three 112 and the hinge connector four 113 are fixedly connected to the chassis hinge connector 201, and the hinge connecto...

Embodiment approach 3

[0050] This embodiment differs from Embodiment 1 and Embodiment 2 in that: the transaxle support 101 and the chassis hinge connector 201 are hinged through a biaxial hinge, and the biaxial hinge includes hinge axis four 114, hinge axis five 115, hinge connection Part five 116, hinge connection part six 117. The four chain shafts 114 and the five hinge shafts 115 are arranged in parallel with different axes, and they respectively run through the drive axle brackets 101 close to the chassis 2 on both sides. Five 116, the hinge connector six 117 is fixedly connected, the hinge connector five 116, the hinge connector six 117 are hollow inside, and both of them are sleeved on the upper side and the lower side of the drive axle bracket 101; the hinge connector five 116, the hinge connector Six 117 are rotatably connected to the drive axle support 101 through thrust bearings 107 respectively. In this embodiment, four thrust bearings 107 are set, see the attached Figure 4 , 2 thrust...

Abstract

The invention relates to the technical field of traffic transportation, and discloses a mobile platform which comprises N chassis and N+1 drive axles, and N is a positive integer larger than or equal to 1. Each drive axle comprises a drive axle support and wheels rotationally connected to the drive axle support, chassis hinge connecting pieces are arranged on the two sides of the chassis respectively, the N chassis and the N+1 drive axles are sequentially arranged at intervals, and the drive axle supports are hinged to the chassis hinge connecting pieces through coaxial hinges or double-shaft hinges. Two ends of each drive axle support are rotationally connected with wheels, the angles of the wheels relative to the drive axle supports are unchanged, and the wheels are provided with wheel driving mechanisms for driving the wheels to rotate. Compared with the prior art, steering is achieved through the differential speed of a left wheel and a right wheel of the vehicle, a complex steering mechanism is omitted, the cost and the weight of the vehicle can be reduced, and meanwhile the vehicle has the expansion capacity.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a mobile platform. Background technique [0002] Mobile platforms, such as wheelchairs, mobile cars, etc., play an important role in many fields such as agriculture, industry, film and television, search and rescue, police, military, etc., and can adapt to complex environments and road conditions. In the operation of the mobile platform, in order to adapt to the complex environment and road conditions, the steering of the vehicle or the mobile platform is required to be flexible and easy to control. Traditional vehicles or mobile platforms have the following problems: [0003] 1) The structure of the steering mechanism of the traditional vehicle is complicated, the cost is high, and the weight of the vehicle itself is large. In actual use, due to the heavy weight of the vehicle body, it is difficult to go straight or turn, and real-time control cannot be achieved while w...
