New description: [New technical field] This case is related to the seat mechanism of electric wheelchairs. More specifically, it is a design that can control the proper angle of seat rotation. [Prior Art] • It is known that the cranes of the Lin Lin need to rely on one to push the two wheels on their own, or rely on the caregiver to push the wheelchair behind. In other words, the makers of the wheelchairs themselves are still equipped with the ability to control and muscle strength. However, for users who lack this ability, the electric wheelchair is the first choice for its action instead of the X. Because the user can control the electric wheelchair with the fingers, the joystick, the switch, etc. Very labor-saving, convenient, and more mobile. However, the users of electric wheelchairs often face great troubles when they are in the upper and lower wheelchairs. The main reason is that the seat of the electric wheelchair is strangely-fixed in the direction of advancement, and the user should watch the position. In a wheelchair, the entire wheelchair must be turned into an angle that is suitable for up and down, very numb and unsafe. [New content] In order to solve the inconvenience of the upper and lower electric wheelchairs, it is better to make the seat rotate the right angle to the left and right. In this case, the rotating seat mechanism is designed. - a rotating seat mechanism for an electric wheelchair, constructed in the main frame of the electric wheelchair; comprising: a power source; a speed reducer driven by the power source; and a pass by the thief speed machine The rotary motion of the reduction gearbox is transmitted to the seat lever of the electric wheelchair; the angle sensing device senses the pivot angle of the seat lever and converts the physical quantity of the sensing into 5 M325108. A plurality of concentrically combined ring gears 21, the inner portion of each of the ring gears 21 is coupled to a planetary gear set 23 assembled by a carrier 22, wherein the planetary gear set 23 of the lowest level layer is directly driven by the power source 10 described above, and the rotary motion is The hierarchical planetary gear set 23 is decelerated and transmitted to the flexible transmission 30 by the planetary gear set 23 of the highest level. The reducer 20 of the present invention is achieved by using a multi-stage planetary gear train, which has the advantage that the specific product is smaller, but it is easy to achieve the expected speed and torque output value. • The flexible transmission 30 includes an active rotating element 31, a passive rotating element 32, and an annular flexible element 33 pivoted over the active and passive rotating elements. The active rotary element 31 is driven by the planetary gear set 23 of the uppermost layer of the above-described multi-step planetary gear train, and the passive rotary element 32 transmits the rotational motion of the active rotary element 31 to the electric wheelchair 6 at a reduction ratio. The seat lever 61 is pivotally mounted in a bearing housing 62 fixed to the main frame of the electric wheelchair. - The angle of rotation of the seat lever 61 described above is monitored by the aforementioned angle sensing device 40. In the embodiment of the present invention, the above-described angle sensing device 4 utilizes a conventional magnetic field sensing technique. Generally, at least the magnetic element 42 is disposed on the outer ring of the seat rod 61, and the ring 41 is disposed on the ring 41, and the fixed position of the ring _ is set to be the element 43. The seat is full of rotation and the magnetic induction element 43 generates relative motion to generate magnetic induction, and the magnetic sensing member 43 is connected to the circuit secret output sensing signal X as a reference for controlling the power source, thereby controlling the seat (10) to rotate to - Stop when the angle is predetermined. The fourth chart is not the above-mentioned power source 1 〇, the reduction gear 2 〇, the flexible transmission device, the angle sensing device 40, and the like are constructed in the electric wheelchair 6 〇 main frame body _ schematic. The main frame is deleted before and after. The battery 67 is mounted on the main frame view to provide the fine rotation after driving and the power required for the power of the case.

Through the disclosure of the above, we can infer that the rotating seat mechanism allows the seat of the electric wheelchair to be aligned forward and left to the right. The angle of turning to the left or to the right is not limited to those disclosed in the drawings. Although this case is based on the record of the real face, but the skilled person can do a variety of different forms of change in the case of the female case. The above embodiments are only used to illustrate the case, and are not intended to be used in this case.
