Description of the Invention: [Technical Field] The present invention relates to a simple auxiliary electric module for a wheelchair, and more particularly to an auxiliary device for a conventional manual wheelchair, thereby providing a component that is compact and stressed. A simple auxiliary electric module that is small, has a long service life, is light in weight, and is easy to operate and disassemble. [Prior Art] Wheelchairs are mainly used for the movement of people with physical disabilities or the elderly. As a means of transportation, wheelchairs enable users to achieve independent and independent needs. Wheelchairs are distinguished by the source of power and can be divided into two types: manual wheelchair virtual wheelchairs. The power source of the manual wheelchair is the user's hands. The dream is to push the handwheel of the wheelchair by both hands. 9 (4) It is the movement of the wheelchair that can be used to improve the user's heart and lung power. The role of the month ti, the lack of basins to other points, slow speed and lack of comfort. The electric cymbal is to use the electric motor to provide the power required for the wheelchair to travel. It only needs to use the control device to dry the stagnation and the speed of travel. The disadvantage of the direction is that it loses the means of transportation that helps the user to travel more comfortably, but at that time Can't be used. Advantages, and when the motor power is insufficient, the sports disk of the integrated manual wheelchair appears - some additional auxiliary 〃 #椅 comfort' on the market, the auxiliary electric drive can be separated or combined with the general manual rotation 4 1335813, The design of the conventional design, such as the national Zhuoli No. 5, 372, "Additional Wheelchair Steering Drive", Patent No. 4,275, "Electric Wheelchair" and No. 3,405, "Wheelchair The actuator, etc., but its structural design is disadvantageous due to its large size, difficulty in disassembly and assembly, and inability to make rapid changes between manual mode and electric mode. To this end, the inventors have developed a "wheelchair assisted electric module with retractable device" for this problem and filed a patent application with the SIPO, the application number is 9411 2541, to solve the above problems, Only the structure of the case is still not concise and heavy, and the weight of the electric wheel set needs to be large, so that the force of the component is large, and the problem that affects the service life is generated. [Summary of the Invention] What is the problem with the easy-to-use electric motor model? In view of the problems described above, the [...] first-time show group is an additional auxiliary device for the traditional manual wheelchair, designed by a lifting group. The lifting group lowers the electric wheel and touches the ground. When the small wheel is pushed off the ground, the electric wheel and the big wheel touch the ground and are in the electric mode. When the lifting group raises the electric wheel and leaves the ground, the small and large wheels are simultaneously landed. And return to the manual mode, thereby providing a wheelchair-assisted electric module with reduced components, low force, long mission, light weight, convenient operation and disassembly. The structural features and techniques of the present invention (4), the "wheel=two electric module" of the present invention, comprising: a convergence group, a retracting group, a direction control group, a squatting button and an electric wheel set, which: 接接. & 3 has - the adapter, and the number of adjustment ends are provided with a groove and at the groove Λ adjustment # outer groove 6 is also attached to the buckle, the adjustment rod can be inserted into the connection 5 1335813 seat 'adjusted according to the width of the wheelchair length. The retracting group includes a pivoting seat and a retracting seat. The pivoting seat is provided with a fixing rod. The fixing rod is inserted into the connecting seat and fixed to the front end of the connecting seat, and the pivoting seat is provided with a pivot hole on each side of the front end of the pivoting seat. The shaft block, wherein one of the pivot blocks is provided with an engaging block at the periphery of the shaft hole, and a screw is disposed through the pivot block and screwed to the spray block. The retracting seat is provided with a shaft hole, which is sleeved between the two frame shaft blocks of the pivoting seat and is pivoted through a pivot hole, and the receiving and locking groups are locked and integrated by screws. The accommodating portion is provided with an engaging portion and the abutting block of the pivot block mutually slid together. The front end of the accommodating seat is provided with an internally threaded sleeve. The direction control group 'includes a control lever, a telescopic rod and a handlebar. The telescopic rod is disposed inside the control rod, and the top end is connected to the handle rod. The lifting group is an externally threaded sleeve, and a handle is pivoted on the outer edge thereof. The outer thread of the sleeve is screwed into the internal thread of the sleeve, and the control of the direction control group is framed in the sleeve. The electric wheel set has a wheel frame and an electric wheel. The wheel frame is functionally connected to the bottom end of the control rod of the direction control group and can be rotated with the control rod. The mandrel of the electric wheel is screwed in the middle of the wheel frame. Thereby, the direction of movement of the electric wheel can be directly controlled by the direction=group.
