Embodiment Construction
[0047] see Figure 1-5 , the present invention relates to a trolley using a small chassis, comprising a bottom plate 102 of the chassis, on which a pair of motors 10 indirectly movable are horizontally arranged, and the two motors 10 are staggered head to tail and arranged side by side, and the two motors 10 The axes are parallel to each other.
[0048] A pair of suspension units 103 including the motor 10 are arranged on the base plate 102 . The two suspension units 103 are interlaced and arranged side by side, and are movably connected to the base plate 102 through connecting pieces.
[0049] like figure 1 , figure 2 As shown, the vertical projections of the top and bottom sides of the bottom plate 102 are in the shape of "H" or after being rotated by 90°, they are in the shape of "I". The four corners on the base plate 102 are respectively provided with a circular hole 102a, and a universal wheel 101 is movable in the circular hole 102a, and the wheel shaft upper end of...

The invention relates to a car with a small chassis. The car with the small chassis comprises a bottom plate, wherein a pair of motors movably connected with the bottom plate indirectly are arranged on the bottom plate horizontally, the heads and tails of the two motors are arranged in a staggered state and side by side, and the axes of the motors are parallel to each other. A pair of suspension units comprising the motors are further arranged on the bottom plate, the two suspension units are staggered with each other and arranged side by side, and movably connected with the bottom plate through a connecting piece; each suspension unit comprises a pair of guide columns, a suspension bracket is sleeved on the two guide columns, a spring and a spring fixing block are arranged on the guide columns; the motors are arranged on the inner sides of the suspension brackets, driving wheels are arranged on the outer sides of the suspension brackets, the axes of the driving wheels carry out translation to the left side relative to the axes of the motors, and the motors are in meshing transmission with the driving wheels; a pair of open slots are symmetrically formed in the bottom plate, guide column connecting holes are formed in two sides of the open slots, universal wheel holes are formed in four corners of the bottom plate, and the suspension units entirely ascend or descend along the axial directions of the guide columns. The heads and tails of the two motor bodies are arranged in a staggered state and side by side, and not mutually interfered, so that the design requirement on a small chassis size is met, and the chassis can successfully pass when meeting uneven ground.
Description
technical field [0001] The invention belongs to the technical field of robots and relates to a small chassis, in particular to a trolley using a small chassis. Background technique [0002] People in the industry know that for a car with a small chassis, when the chassis is reduced to a certain size, the overall design and layout of the motor will often have a bottleneck. Therefore, the driving wheels of the two-wheel differential robot chassis must adopt a suspension structure. [0003] However, when the chassis of the robot is reduced to a certain size, the remaining space of the chassis is very small, and it is impossible to install a more complicated suspension mechanism at all. [0004] Therefore, how to design a motor layout with a reasonable structure and install it on a robot chassis with a small space, and at the same time ensure that the chassis can still pass smoothly when the robot encounters uneven ground during operation is becoming more urgent and important. ...
