Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.
[0026] As shown in the utility model provides a kind of technical scheme: Figures 1-5
[0027] A wheeled electric power-assisted stroller structure, including car body 1, the upper end of car body 1 is horizontally provided with car plate 2, folding extension mechanism is provided at the top of car body 1 both sides, folding extension mechanism includes sleeve pipe 5, sleeve pipe 5 is horizontally provided at the top of both sides of car body 1, the inside both ends of sleeve pipe 5 are movably sleeved with two-layer pipe 6, L-shaped pipe 7 is provided at the outside one end of two-layer pipe 6;
[0028] In the embodiment, when the carrying capacity of the stroller needs to be expanded to load more materials, two-layer pipe 6 can be pulled out of sleeve pipe 5, so as to increase the effective use area of car plate 2, when the area does not need to be expanded, two-layer pipe 6 can be pushed back into sleeve pipe 5, to realize the folding of the structure, and facilitate the storage and movement of the stroller in narrow space.
[0029] For example, when it is necessary to transport bulky materials, such as tents, large equipment parts, etc., the folding extension mechanism can be unfolded, and when passing through a narrow forest path, it can be folded up.
[0030] As shown in the utility model provides a kind of technical scheme: Figure 2 And Figure 3 As shown in the utility model provides a kind of technical scheme:
[0031] In the embodiment, battery 9 provides power for the entire electric drive system, and the operator sends control signals to electric controller 8 through hand control box 10, and electric controller 8 controls the operation of electric drive bridge assembly 3 according to the received signals, and then drives wheel 4 to rotate, to realize the forward movement, backward movement, acceleration and deceleration of the stroller.
[0032] For example, the operator presses the forward button on hand control box 10, and after electric controller 8 receives the signal, adjusts the output power of electric drive bridge assembly 3, so that wheel 4 rotates forward, and the stroller starts to move forward.
[0033] As Figure 4 shown, a damping mechanism is arranged between the electric drive axle assembly 3 and the vehicle body 1, which includes swing arms 11, swing arms 11 are arranged on both ends of the electric drive axle assembly 3, one end of the swing arm 11 is movably connected with the bottom end of the vehicle body 1, the other end of the swing arm 11 movably arranged with air damping 12, the other end of the air damping 12 is movably connected with the upper end of the vehicle body 1, the anti-roll pull rod 13 movably connected with the swing arm 11 is arranged on both sides of the bottom end of the vehicle body 1;
[0034] In this embodiment, when the trolley runs on uneven road surface, the wheels 4 will be impacted by the ground, the impact force is transmitted to the air damping 12 through the swing arm 11, the air damping 12 absorbs and buffers the impact force by the elastic deformation of the internal compressed air, reduces the vibration of the vehicle body 1, improves the stability and comfort of the trolley running, at the same time, the anti-roll pull rod 13 can limit the lateral swing of the swing arm 11, prevent the trolley from tilting during running.
[0035] For example, when the trolley passes through a pit, the wheels 4 jump up, the swing arm 11 moves, the air damping 12 is compressed, and most of the impact force is absorbed, so that the vehicle body 1 will not produce violent vibration.
[0036] Working principle: when the troops need to transport materials, if the volume of the materials is large, the second layer pipe 6 of the folding and expanding mechanism can be pulled out of the sleeve pipe 5, the L-shaped pipe 7 is unfolded, the carrying capacity of the trolley board 2 is expanded to load more materials; if it is necessary to store or move the trolley in a narrow space, the second layer pipe 6 is pushed back into the sleeve pipe 5 to realize folding. In terms of electric drive system, the battery 9 provides power for the whole system, the operator sends control signals to the electric controller 8 through the hand control box 10, the electric controller 8 controls the operation of the electric drive axle assembly 3 according to the signals, and then drives the wheels 4 to rotate, realizes the forward and backward movement, acceleration and deceleration of the trolley. During the running of the trolley, if uneven road surface is encountered, the ground impact force received by the wheels 4 will be transmitted to the air damping 12 through the swing arm 11, the air damping 12 absorbs and buffers the impact force by the elastic deformation of the internal compressed air, reduces the vibration of the vehicle body 1; at the same time, the anti-roll pull rod 13 limits the lateral swing of the swing arm 11, prevents the trolley from tilting, and ensures the stability and comfort of running. In addition, in the night or dim light environment, the operator can turn on the illuminating lamp 14 arranged on both sides of the top end of the vehicle body 1 through the control device, provide lighting for the trolley running, ensure to see the road conditions, and ensure the safety of transportation.
