This two-wheeled electric vehicle can carry 2-3 people at a time, and two people can ride simultaneously to improve teamwork ability, which is more suitable for parent-child outings. However, most two-wheeled electric vehicles cannot guarantee the safety of children on the vehicle. Moreover, although the two-wheeled electric vehicle has four-wheel drive, tourists can rest on the seat after stopping, but most tourists have to put their feet on the pedals to sit firmly, which is an uncomfortable way to rest.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-7 A dual-drive four-wheel electric vehicle comprises a dual-drive four-wheel electric vehicle body 1, seat rods 2 are symmetrically arranged at the middle of the frame on both sides of the dual-drive four-wheel electric vehicle body 1, a seat unit 4 is arranged at the upper end of the seat rod 2, a child seat structure 6 is arranged on the seat unit 4, a battery box 8 is arranged at the rear side of the seat unit 4, motors 7 are connected and installed on the bicycle rear wheels on both sides of the dual-drive four-wheel electric vehicle body 1, and the motor 7 is driven by the battery box 8, frame lower tubes 3 are arranged on the frames on both sides of the dual-drive four-wheel electric vehicle body 1 and located in front of the seat rod 2, a connecting frame 31 is arranged on the tube body of the frame lower tube 3, and pedal units 5 are symmetrically arranged on both sides of the connecting frame 31;

[0024] The pedal unit 5 includes a fixed plate 51, which is symmetrically fixedly connected to both sides of the connecting frame 31. A pedal 52 is rotatably provided on one side of the fixed plate 51, and a supporting structure 53 is symmetrically provided on the upper surface of the fixed plate 51 and at the connection with the pedal 52.

[0025] Among them, the seat unit 4 includes a fixed base plate 41, which is horizontally arranged at the top of the seat rods 2 on both sides, a seat cushion 42 is horizontally arranged on the fixed base plate 41, a child seat structure 6 is arranged in the middle of the seat cushion 42, a fixed frame 43 is symmetrically arranged on the rear side of the fixed base plate 41, and a first backrest cushion 44 is fixedly connected to the front side of the upper part of the fixed frame 43, and the first backrest cushion 44 is convenient for tourists to lean on when resting.

[0026] In addition, the child seat structure 6 includes a connecting rod 61, the bottom end of which is fixedly connected to the middle of the rear side of the fixed bottom plate 41, a handlebar frame 64 is provided in the middle of the front side of the fixed bottom plate 41, a second backrest pad 62 is fixedly connected to the front side of the upper part of the connecting rod 61, and armrests 63 are symmetrically provided on both sides of the second backrest pad 62. The armrests 63 can effectively limit the movement of children, prevent children from moving around or shaking when the car shakes, causing the children to slide down, and play a better protective role.

[0027] Moreover, a rotating groove 511 is symmetrically provided on the rear side of the upper surface of the fixed plate 51, and a rotating shaft 512 is arranged in the rotating groove 511. The foot pedal 52 rotates around the rotating shaft 512. A rotating block 521 is symmetrically fixed to the front end of the foot pedal 52. The rotating block 521 is arranged to rotate on the rotating shaft 512. The upper surface of the foot pedal 52 can be pressed against the supporting structure 53 by rotation. After the foot pedal 52 and the fixed plate 51 are spread out, tourists who stop to rest can put their legs flat on it, or they can put food and other things on it for tourists to take when they are resting.

[0028] Meanwhile, the support structure 53 includes a support rod 531 , the bottom end of the support rod 531 is fixed to the upper surface of the fixing plate 51 , and a top plate 532 is fixed at an angle to the top of the support rod 531 .

[0029] In the present embodiment, when tourists ride the dual-drive parallel four-wheel electric vehicle body 1 in a scenic spot, they can place children on the child seat structure 6. The children sit on the seat cushion 42, and there are armrests 63 on both sides. The armrests 63 can protect the children, and the handlebar frame 64 at the front end is convenient for providing children with the fun of riding a bicycle, preventing tourists with children from just sitting there while riding, which would cause distress. The handlebar frame 64 allows children to play with it, so that couples can ride with peace of mind, and the second backrest pad 62 is convenient for children to lean on.

[0030] Two tourists sit on the cushions 42 on both sides. Before riding, they turn all the pedals 52 and press the pedals 52 against the top plate 532 of the supporting structure 53, so as to store the pedal units that were originally spread out flat, which is convenient for tourists to ride. Once they are tired during riding, the two-wheeled electric vehicle is different from ordinary two-wheeled bicycles. Tourists of the two-wheeled electric vehicle can stop and rest at any time on the two-wheeled electric vehicle body 1, because the pedals 52 against the inclined top plate 532 allow tourists to step on the inclined pedals 52 and rest on the first backrest pad 44 without putting their feet on the easily rotated pedals to rest.

[0031] When tourists stop to rest for a long time at a scenic spot, they stop the dual-drive parallel four-wheel electric vehicle body 1 and turn all the pedals 52 to spread them out. After the pedals 52 and the fixing plate 51 are spread out, the tourists who stop to rest can put their legs flat on them, or put food and other things on them for the tourists to take when they are resting.

[0032] Moreover, the bicycles on both sides of the dual-drive four-wheel electric vehicle body 1 are connected and fixed by a mortise and tenon structure, so that the bicycles on both sides of the dual-drive four-wheel electric vehicle body 1 are detachable and separable, and the motor 7 is arranged on the rear wheels on both sides for driving the bicycles, and the motor 7 is driven by the battery box 8 to synchronize the rear wheels, and a controller is also arranged in the battery box 8, so that the dual-drive four-wheel electric vehicle as a whole is an electric bicycle. These structures are all existing technologies and are necessary knowledge well known to people in the field of electric bicycles, and there is no need to elaborate on them.

[0033] In the utility model, the child seat structure 6 is provided to facilitate tourists who carry children when riding. The children can be placed behind the child and the handrail 63 can also play a protective role. The handlebar frame 64 is provided for children to play, and the children will not make noise, which is convenient for tourists on both sides to ride with peace of mind. By rotating the foot pedal 52 on the inclined top plate 532, tourists can step on the inclined foot pedal 52 and lean on the first backrest pad 44 to rest, without having to put their feet on the easily rotated foot pedal to rest. The horizontally spread foot pedal 52 is convenient for tourists who stop to rest to put their legs flat on it for a long time to rest, or they can put food and other things on it for tourists to take when they are resting. This makes the functions of the dual-drive parallel four-wheel electric vehicle more comprehensive.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
