[0033] Please refer to Figures 4-6, in this embodiment, sliders 1202 are fixed at both the front and rear ends of the positioning rod 1107. The sliders 1202 are slidably connected to the chute 1203. The chute 1203 is an arc-shaped structure and is opened at the front end of the first auxiliary bracket 2. By sliding the sliders 1202 in the chute 1203, the positioning rod 1107 can move smoothly, playing a guiding role. The monitoring component 15 further includes a first mounting plate 1501. The rear end of the first auxiliary bracket 2 is fixedly connected to the first mounting plate 1501. A first position sensor 1502 is fixedly installed at the upper end of the first mounting plate 1501. Through the real-time monitoring of the first position sensor 1502, once the positioning rod 1107 reaches this position, it will immediately convert and transmit the signal to turn off the dual-axis motor 1101. The rear end of the first auxiliary bracket 2 is fixedly connected to a second mounting plate 1503. A second position sensor 1504 is fixedly installed at the right end of the second mounting plate 1503. Through the real-time monitoring of the second position sensor 1504, once the positioning rod 1107 reaches this position, it will immediately convert and transmit the signal to the total control 8 to turn off the dual-axis motor 1101. The left end of the fixed reinforcing rod 6 is fixedly connected to a third mounting plate 1505. A rain sensor 1506 is fixedly installed at the upper end of the third mounting plate 1505. Through the rain sensor 1506, real-time monitoring can be carried out. Once it rains, it will convert and transmit the signal to the total control 8, thereby turning on the dual-axis motor 1101. A light sensor 1507 is fixedly installed at the upper end of the third mounting plate 1505. A thermometer 1508 is fixedly installed at the upper end of the third mounting plate 1505. Through the light sensor 1507 and the thermometer 1508, real-time monitoring can be carried out. Once the temperature and light intensity exceed the set value, the signal will be converted and transmitted to the total control 8, thereby turning on the dual-axis motor 1101.

[0034] During operation, the rain sensor 1506, the light sensor 1507, and the thermometer 1508 will monitor the weather conditions in real time. Once the temperature and light intensity exceed the set value, the signal will be converted and transmitted to the total control 8, thereby turning on the dual-axis motor 1101. The main gear 1104 is driven to rotate by the first output shaft 1102 and the second output shaft 1103. At the same time, it cooperates with the sleeve 1106 to rotate in the rotating shaft 10, so that the driven gear 1105 rotates, thereby driving the positioning rod 1107 to rotate and driving the slider 1202 to slide directionally in the chute 1203. Then the first position sensor 1502 will monitor. Once the slider 1202 on the positioning rod 1107 reaches this position, it will immediately convert and transmit the signal to turn off the dual-axis motor 1101, and the dark sunshade cloth 13 can be unfolded. Similarly, once it rains, the rain sensor 1506 will convert and transmit the signal to the total control 8, thereby turning on the dual-axis motor 1101 and cooperating with the second position sensor 1504 for monitoring, and then the transparent rainproof cloth 14 can be unfolded.

[0035] Through the above steps, it is convenient to shade or shield rain for users sitting outdoors by using a dark sunshade cloth and a transparent rain shield cloth. The cooperation of the driving component and the driving positioning component facilitates adjusting the positions of the dark sunshade cloth and the transparent rain shield cloth according to the usage needs. And through the monitoring component, it can automatically sense environmental changes and thus automatically adjust the dark sunshade cloth and the transparent rain shield cloth to solve the problems of inconvenient operation, low automation level, poor stability and single function of the wheelchair sunshade and rain shield.

[0036] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
