Description

Technical Field

[0001] This utility model relates to the field of electric wheelchair technology, and in particular to a novel folding electric wheelchair. Background Technology

[0002] In the current field of electric wheelchair technology, most electric wheelchairs suffer from complex folding structures and cumbersome operation. Folding them often requires multiple steps and consumes considerable time and effort, which is extremely inconvenient for users with mobility impairments. Furthermore, the folded wheelchair remains bulky, making it difficult to store in a vehicle trunk or carry around. Additionally, some electric wheelchairs lack functional integration; for example, the design of armrests and storage spaces is not well-considered, failing to meet the diverse needs of users. Therefore, it is necessary to design a new type of folding electric wheelchair to address these shortcomings of existing technology. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a new type of folding electric wheelchair with a reasonable structural design, convenient folding, easy portability, and rich functions.

[0004] To achieve the above and other related objectives, the technical solution provided by this utility model is: a novel folding electric wheelchair, including a front fork arm, a backrest support, a seat support and a connecting rod support hinged between the front fork arm and the backrest support. The front fork arm, the backrest support, the seat support and the connecting rod support together form a quadrilateral frame structure that can be folded or unfolded. The bottom of the front fork arm is provided with two sets of front wheels, and the bottom of the backrest support is provided with two sets of electric rear wheels. It also includes a telescopic rod, one end of which is hinged to the backrest support and the other end of which is hinged to the seat support. The telescopic rod is configured to control the quadrilateral frame structure to switch between folded and unfolded postures.

[0005] A preferred technical solution is as follows: it further includes an armrest, which is hinged to the seat plate bracket. The armrest is provided with a press-type spring pin, and the seat plate bracket is provided with a pin hole. The press-type spring pin is correspondingly provided with the pin hole. The press-type spring pin and the pin hole are configured to control the armrest to switch between two postures: folded or unfolded.

[0006] The preferred technical solution is as follows: the telescopic rod consists of a support rod and a sleeve. One end of the support rod is hinged to the bottom of the seat plate bracket, and the other end is inserted into the sleeve. The support rod has a first lock hole and a second lock hole. One end of the sleeve is fitted onto the outer periphery of the support rod, and the other end is hinged to the bottom of the backrest bracket. The sleeve has an electric spring pin. The pin shaft of the electric spring pin extends into the sleeve and is correspondingly matched with the first lock hole and the second lock hole. When the pin shaft of the electric spring pin extends into the first lock hole, the quadrilateral frame structure remains in an unfolded posture. When the pin shaft of the electric spring pin extends into the second lock hole, the quadrilateral frame structure remains in a folded posture.

[0007] The preferred technical solution is as follows: the electric rear wheel consists of a battery, a hub motor and a rear wheel. The hub motor is fixed on the backrest bracket and is used to drive the rear wheel to rotate. The backrest bracket is provided with a mounting base. The battery is detachably assembled in the mounting base and is used to supply power to the hub motor.

[0008] A preferred technical solution is that a pedal is hinged to the front bottom of the front fork arm.

[0009] A preferred technical solution is that the connecting rod bracket is located on the bottom side of the seat plate bracket, and a detachable storage basket is provided on the bottom side of the connecting rod bracket.

[0010] A preferred technical solution is as follows: an unlocking switch is provided at the bottom front side of the seat plate bracket, and the unlocking switch is connected to the electric spring pin to control the extension or retraction of the electric spring pin.

[0011] A preferred technical solution is that the armrest is equipped with a control unit, which is connected to the hub motor and is used to control the working state of the hub motor.

[0012] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0013] This utility model provides a novel folding electric wheelchair. Through a quadrilateral frame structure composed of a front fork arm, backrest support, seat support, and connecting rod support, combined with the control of a telescopic rod, the wheelchair can be easily folded and unfolded. The operation is simple, greatly saving the user's time and energy. The foldable armrests further reduce the wheelchair's size when folded, making it easier to store and carry. The telescopic rod uses a support rod and sleeve structure, and through the cooperation of an electric spring pin and a locking hole, it can stably maintain the wheelchair's unfolded or folded posture, ensuring safety and reliability. The electric rear wheels are driven by a hub motor, and with a removable battery, it not only provides ample power but also facilitates battery charging and replacement. The footrest hinged at the bottom of the front fork arm provides a comfortable footrest position for the user, improving comfort. The removable storage frame on the bottom side of the connecting rod support increases the wheelchair's storage space, making it convenient for the user to carry items. The unlocking switch at the bottom front of the seat support and the control unit on the armrest allow the user to easily control the wheelchair's folding and driving status, improving operational convenience.
