Folding electric wheelchair vehicle

Abstract

Provided is a folding electric wheelchair vehicle. The folding electric wheelchair vehicle comprises a chair seat frame, a chair back frame and a pair of armrests, wherein a pedal is hinged to the rear end of a vehicle frame, the front end of the vehicle frame is hinged to a reversing frame, and one side of the upper end of a left battery box is provided with a first walking wheel assembly; the lower end of the left battery box is provided with a first driving wheel assembly, one side of the upper end of a right battery box is provided with a second walking wheel assembly, and the lower end of the right battery box is provided with a second driving wheel assembly; one of the armrests is provided with a remote controller. The folding electric wheelchair is characterized in that the front end of the chair seat frame is provided with a front horizontal pipe of the chair seat frame, and the chair seat frame is provided with a left hook plate seat and a right hook plate seat; the lower parts of the left and right side of the chair back frame are provided with a left hinge seat and a right hinge seat of the chair back frame, and one side of the left or right hook plate seat is provide with a snap mechanism; the side, facing upward, of the left battery box is supported through the middle of the left side of the chair seat frame, and the side, facing upward, of the right battery box is supported through the middle of the right side of the chair seat frame; the upper part of the reversing frame is hinged to the front horizontal pipe of the chair seat frame, and the lower part of the reversing frame is hinged to the sides, facing upward, of the lower parts of the left and right battery boxes. According to the folding electric wheelchair vehicle, the structure is simplified, the security is ensured, and unlocking and storing are convenient; no damage is caused to the left and right battery boxes, feet are comfortable on the wheelchair, and tipping is avoided.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to a foldable electric wheelchair. Background technique [0002] Electric wheelchairs, also referred to as electric wheelchairs for short, are transportation tools for special groups such as disabled, elderly and infirm, and medical and clinical rehabilitation patients. There is no shortage of technical information about electric wheelchairs in the published Chinese patent documents, such as the "multifunctional electric wheelchair" (four-wheel structure) recommended by the authorized announcement number CN2745544Y. Fold in the direction of the seat, and put the seat against the direction of the bottom plate, and finally reflect the folding effect in the state of non-use or storage. However, no matter in the state of use or in the folded state, the positions of the pedals and the front wheels have not changed, that is to say, the pedals and the front wheels do...

Problems solved by technology

[0005] But above-mentioned CN102764185B still has following shortcoming: one, owing to need to be pulled backguy by car owner or accompanying person when folding, make the locking pin of backguy two ends withdraw from the flip plate locking hole on the back support pipe, make the seat frame and the back of the chair The locking relationship between the support tubes is released, so it is necessary to add a seat back support tube between the two sides of the seat frame and the two sides of the seat back frame. The frame is hinged, and the end facing the seat frame is hinged with the seat frame and the rear support tube at the same time in the state of cooperating with the aforementioned stay wire locking pin, which not only increases the complexity of the structure, but also has many hinge points. Assembly is troublesome, especially because of the many hinge points that make folding difficult; second, because the backguy is essentially a steel wire with a sheath, the locking pins at the two ends of the backguy, that is, the steel wire, correspond to the locking pin holes on the seat frame. It is difficult to ensure the exact position of the seat back support tube to be locked by the flip plate locking hole on the seat back support tube under the chair back support tube at the position inserted into the seat back support tube at the correct position, and the locking reliability is relatively low, because once the cable is pulled too hard, Then there is a risk that the locking pin will come out of the locking pin hole as a whole, and a false lock will appear when it is locked again, and because when the lengthy pull wire is hit by a foreign object such as an object placed on the seat cushion, the user's finger is accidentally hooked, or other similar In other cases, there will be abnormal unlocking, and even safety accidents; third, because the pulling operation of the pull wire is relatively laborious, it is not suitable for people with limited physical fitness, such as the aforementioned disabled, elderly and infirm, and medical and clinical rehabilitation patients. Four, because the limit stop feet supported by a pair of rear brackets are arranged on the opposite side of a pair of battery boxes, it is easy to cause tearing damage to a pair of battery boxes or cause the limit stop feet to be separated from each other. The battery box is separated; fifthly, since the two sides of the pedal, that is, the pedal board, are hinged to the front support tube through a pedal tube hinge pin, and because the pedal tube hinge pin does not have a reasonable locking force on the pedal, the pedal is prone to abnormal Flip freely, affecting the comfort or comfort of the occupant's feet
