Problems solved by technology

[0002] Early electric wheelchairs were designed to use the speed coordination between the two motors to achieve the purpose of traveling and turning. This type of electric wheelchair has a complex structure, high cost, and difficult maintenance. Therefore, the applicant of the present invention has made improvements to the above deficiencies. design a figure 1 , 2 As shown in the electric wheelchair, the electric wheelchair 1 mainly includes: a base 11, a power mechanism 12, a differential mechanism 13, a control mechanism 14 and a steering mechanism 15, wherein the base 11 is at the bottom of a chair frame 111 Four wheels 112 are installed, and an intubation base 113 is set at a position on one side of the chair frame 111, and the power mechanism 12 is installed on the base 11 to provide the power for the electric wheelchair 1 to move. The differential mechanism 13 is It is used to control the rotational speed difference of the rear two wheels 112, and the control mechanism 14 has a linkage rod 141 inserted on the intubation base 113, a hand wheel 142 located at the top of the linkage rod 141, a power mechanism that can start 12 of the control seat 143 and a swing seat 144 installed on the bottom end of the linkage rod 141, wherein the swing seat 144 has a swing plate 145, and the steering mechanism 15 is erected between the front two wheels 112, and with the swing seat 144 The swinging piece 145 moves in unison to control the direction of travel of the electric wheelchair 1
[0003] Although the design of the aforementioned existing electric wheelchair 1 using mechanical means to control the steering can reduce production costs and is also very convenient in maintenance, but in design, because the handwheel 142 of the control mechanism 14 must be erected on one side of the base 11, although the design The installation position of the control mechanism 14 can be changed to meet the needs of customers, but the position of the handwheel 142 for the user to control is fixed after installation, and the user must use a specific hand to control it, which cannot be easily controlled with both hands. This is the electric wheelchair 1 Bad design

Abstract

The electric wheel chair includes a base seat, on said base seat, a power mechansm, a differential mechanism for regulating rotating speed difference and a steering mechanism. In order to do not affect convenience for incoming and outcoming, at the same time of making user utilize two hands to operate and control a supporting mechansm is mounted on one side of the base seat, the interior of the supporting mechanism is equipped with a turning shaft coupled with steering mechanism, an operation-control mechanism is mounted on the turning shaft, and a cycloidal seat of said operation-control mechanism has a pivot point and a cycloidal portion which are space and arranged, said pivot point portion is mounted on the turning shaft, and on the cycloidal portion a hand wheel which is coupled with turning shaft by means of coupling mechanism is assembled, said hand wheel can be turned to side of base seat.

Description

【Technical field】 [0001] The invention relates to an electric wheelchair, in particular to an electric wheelchair conveniently controlled by both hands. 【Background technique】 [0002] Early electric wheelchairs were designed to use the speed coordination between the two motors to achieve the purpose of traveling and turning. This type of electric wheelchair has a complex structure, high cost, and difficult maintenance. Therefore, the applicant of the present invention has made improvements to the above deficiencies. design a figure 1 , 2 As shown in the electric wheelchair, the electric wheelchair 1 mainly includes: a base 11, a power mechanism 12, a differential mechanism 13, a control mechanism 14 and a steering mechanism 15, wherein the base 11 is at the bottom of a chair frame 111 Four wheels 112 are installed, and an intubation base 113 is set at a position on one side of the chair frame 111, and the power mechanism 12 is installed on the base 11 to provide the power...
