The handicapped moped 1 also includes an inclination sensor 22, which is arranged on the seat body 21 (preferably at the bottom of the seat body 21) and is used to sense the seat 2 (specifically the seat body 21) the inclination. The lower frame 4 includes at least one (for example, including but not limited to 1, 2, 3, 4, 5 or 6) arc-shaped members 41 . In the preferred embodiment of FIG. 1 , the lower frame 4 includes two arc-shaped members 41 respectively arranged on the left and right sides of the moped 1 for the disabled. The arc-shaped member 41 extends in the front-rear direction of the moped 1 and has the same curvature in this direction. More specifically, the same curvature of the arc-shaped member 41 means that the curvature value of the arc-shaped portion of the member is constant (the curvature does not change). Further, the upper frame 3 includes a connector that cooperates with the arc member 41 and the size and shape of the connector are set to be suitable for the arc member 41 and the connector to slide relative to each other; the upper frame 3 passes through the connector It is arranged on the arc-shaped member 41 and can slide on the arc-shaped member 41 along the front-rear direction of the bicycle 1, thereby changing the inclination of the upper frame 3 and the seat 2 (specifically, the seat body 21). Preferably, the arc-shaped member 41 is two arc-shaped brackets 41 connected to each other; the main purpose of the connection of the two is to help define the absolute position of the two and the relative position between the two, and this connection does not in any way The movement of the upper frame 3 and the lower frame 4 relative to each other is influenced. Specifically, the two arc-shaped brackets 41 extend along the front-rear direction of the wheelchair 1 ; and each arc-shaped bracket 41 has two ends, and each end is provided with one of the four wheels.

It should be understood that the slidable installation referred to herein means that the two installed together can slide relative to each other.

In addition, the wheelchair 1 according to the present invention also includes a driving device and a computer-based controller (not shown in the drawings). The driving device is fixed on the lower frame 4 and is used to drive the above-described upper frame 3 to slide relative to the lower frame 4 (or the sliding sleeve 34 to slide relative to the arc member 41 ). A computer based controller is in signal communication with the inclination sensor 22 and the drive means and is provided on one of the following components: the seat 2 , the upper frame 3 and the lower frame 4 . When the signal received from the inclination sensor 22 shows that the inclination of the seat body 21 exceeds the maximum limit, the controller sends an instruction to the driving device, and the driving device drives the upper frame 3 to slide along the arc member of the lower frame 4 , so that the seat body 21 returns to the horizontal state. As an example, the maximum limit of the above inclination is generally between 10° and 30° and is most preferably 20°, the specific value depends on factors such as the size, structure, and tolerance of the user to the inclination state of the moped, and the The value can be set to be adjusted by the user. When the inclination sensor 22 sensed that the seat body 21 returned to a horizontal state, the sensor 22 sent a signal to the computer-based controller and the controller sent an instruction to command the driving device to stop the driving action, thereby keeping the seat body 21 in a horizontal state. It should be understood that the computer-based controller referred to in the present invention means that the controller communicates with an external computer or an internal computer (for example, a single-chip microcomputer) so that it can better control the computer with the help of the computer. Complete the control work on the components. Preferably, each of the aforementioned two arc-shaped supports 41 includes a beam 42 arranged horizontally, and the driving device is four hydraulic cylinders arranged on the beam 42 .

Next, referring to FIG. 2 and FIG. 3 , and on the basis of observing FIG. 2 and FIG. 3 in combination with FIG. 1 , the seat inclination adjustment process of the moped 1 for the disabled according to the present invention will be described. Fig. 2 is another side view of the computer-controlled moped for the disabled according to the present invention, in which the moped for the disabled is in an uphill state. Fig. 3 is another side view of the computer-controlled moped for the disabled according to the present invention, in which the moped for the disabled is in a downhill state. As shown in Fig. 1, the wheelchair 1 according to the utility model is placed on the level ground and its four wheels 5 contact the ground to support the seat 2, the upper frame 3 and the lower frame 4 of the bicycle 1. Now, the inclination sensor 22 senses that the seat body 21 is in a horizontal state and the user can sit comfortably on the seat body 21, and the driving device will not make a driving action, so the seat body 21 remains in this horizontal state . Preferably, in the horizontal state, a certain hydraulic pressure can be maintained in the driving device (specifically, the hydraulic cylinder), so that the seat 2 and the upper frame 3 can be more stably maintained in the horizontal state. As shown in Figure 2, according to the utility model, the handicapped bicycle 1 is placed on the ground inclined upwards, and the seat 2, the upper frame 3 and the lower surface of the bicycle 1 are also supported by its four wheels 5 contacting the ground. Frame 4 etc. In this application, the state of the moped 1 for the disabled in FIG. 2 on the upwardly inclined ground is called the uphill state, and the arrow parallel to the ground shown in the figure indicates the forward direction of the moped 1 . At this time, the inclination sensor 22 senses that the seat body 21 is in an upwardly inclined state and the user will feel that the ride is very uncomfortable and its center of gravity moves backward. fall), throwing the user off the vehicle. Therefore, at this time, the controller will instruct the driving device to make a driving action in time, so that the seat body 21 returns to its horizontal state. Specifically, when the signal received by the controller from the inclination sensor 22 indicates that the angle of the seat 2 tilting backward exceeds the maximum limit—for example, 20 degrees, the controller sends an instruction to the rear hydraulic cylinder, commanding the The rear hydraulic cylinder drives the upper frame 3 to slide forward along the arc member 41 of the lower frame 4, so that the upper frame 3 and the seat 2 return to a horizontal state. At this time, the front side hydraulic cylinder can be depressurized, or only maintain a weak pressure, as long as the upper frame 3 and the seat 2 can slide forward smoothly. As shown in Figure 3, according to the utility model, the handicapped bicycle 1 is placed on the ground inclined downwards, and the seat 2, the upper frame 3 and the upper frame 3 of the bicycle 1 are also supported by its four wheels 5 contacting the ground. Get off the frame 4 and so on. In this application, the state of the moped 1 for the disabled in FIG. 3 on the downwardly inclined ground is called the downhill state, and the arrow parallel to the ground shown in the figure indicates the forward direction of the moped 1 . Similarly, at this time, the inclination sensor 22 senses that the seat body 21 is in a downwardly inclined state and the user will feel that the ride is very uncomfortable and its center of gravity moves forward. or fall forward), throwing the user off the vehicle. Therefore, at this time, the controller will instruct the driving device to make a driving action in time, so that the seat body 21 returns to its horizontal state. Specifically, when the signal received by the controller from the inclination sensor 22 indicates that the forward tilt angle of the seat 2 exceeds the maximum limit—for example, 20 degrees, the controller sends an instruction to the front hydraulic cylinder, commanding the The front side hydraulic cylinder drives the upper frame 3 to slide backward along the arc member 41 of the lower frame 4, so that the upper frame 3 and the seat 2 return to a horizontal state. At this time, the rear side hydraulic cylinder can be depressurized, or only maintain a weak pressure, as long as the upper frame 3 and the seat 2 can slide backward smoothly. Although the power-assisted bicycle 1 in Fig. 2 and Fig. 3 is placed on the ground inclined forward or backward, its seat body 21 is in a horizontal state after position adjustment. In addition, it is also easy to understand that no matter whether the wheelchair 1 according to the utility model is placed on a level ground or on a non-level ground where the bicycle 1 is in an uphill or downhill state, as long as the inclination sensor 22 senses the seat When the chair body 21 is in a non-horizontal state (that is, the inclination exceeds the maximum limit), the controller instructs the driving device to drive the upper frame 3, and thus drives the seat body 21 to return to its horizontal state. In addition, preferably, the upper frame 3, the lower frame 4, the ribs 31 and the beams 42 are all made of lightweight and durable aluminum alloy.
