Embodiment Construction
[0037] The present invention will be further explained below in conjunction with the accompanying drawings.
[0038] A rear-wheel-driven electric four-wheel skateboard includes a skateboard body and four runners. Hub motors are installed on the two runners at the rear of the skateboard body, and Hall sensors for detecting rotational speed are installed on the hub motors. like figure 1 As shown, four dual-arm bridge pressure detectors are fixed on the surface of the main body of the skateboard, two of which are arranged side by side at the front of the board at intervals laterally, and the other two dual-arm bridge pressure detectors are arranged side by side at the front of the board. The bridge pressure detectors are arranged laterally and side by side at the rear of the board, and a gyro sensor is also installed at the geometric center of the board. A controller is installed on the main body of the skateboard, and the controller is connected to two sets of double-arm bridge...

The invention discloses a rear wheel drive type electric skate scooter. The rear wheel drive type electric skate scooter comprises a scooter body and four rotary wheels. Hub motors are mounted on thetwo rotary wheels located on the rear portion of the scooter. Four double bridge type pressure sensors are fixed to a plate face of the scooter body, and each double bridge type pressure sensor comprises two bridge type pressure detecting circuits composed of strain gauges, the four double bridge type pressure sensors are transversely arranged on the front portion and the rear portion of the plateface in pairs at intervals. A controller is connected with two double bridge type pressure sensors and the hub motors. The controller comprises a speed control module, and the hub motors are controlled to speed up or slow down to operate according to the difference value f the double bridge type pressure sensors on the front portion and the rear portion of the plate face. According to the rear wheel drive type electric skate scooter, in order to adapt to different users and avoid velocity jump, the four double bridge type pressure detectors are arranged on the front portion and the rear portion of the plate face respectively, the control intention of all postures of the users is accurately detected, and it is ensured that the gravity centers of the users are stable.
Description
technical field [0001] The invention relates to a rear-wheel drive electric four-wheel skateboard. Background technique [0002] Common electric slider control methods on the market can be divided into handheld remote control and center of gravity control, and can be divided into external belt motor and hub motor according to the driving method. For the existing center of gravity control type electric skateboards, the problem of poor stability usually occurs when they are used, that is, the speed is prone to sudden changes, which makes it difficult for the user to control, and is prone to operation accidents. Double-arm bridge-type pressure detector, and each user's manipulation posture is different. Contents of the invention [0003] Purpose of the invention: Aiming at the above-mentioned prior art, a rear-wheel drive electric four-wheel skateboard is proposed to reduce the problem of sudden change in speed during the use of the center-of-gravity control electric four-wh...
