Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
embodiment 1
According to Fig. 1, Fig. 2, a kind of Self-balancing electronic two-wheel car described in the present embodiment, includes two wheels 1, and wheel inner circumferential is torque motor, torque motor is electrically connected with the mouth of controller, two torque motors is also separately installed with the sensor be connected with controller signals input end, the internal stator side of torque motor is fixedly connected on a mount pad 12, mount pad is connected with pedal 2 away from the side of wheel, mount pad is positioned at pedal rotated down and is connected with Connection Block 13, the rotational angle range that Connection Block is mounted opposite seat is 1-10 °, the turning cylinder of mount pad and Connection Block with axletree to parallel, between Connection Block 13 described in two by one interlock seat 3 connect, and interlock seat two ends and two Connection Blocks all hinged, in articulated position, two stepping motors in order to control to link seat length direction and Connection Block corner dimension are installed between described interlock seat and the Connection Block of both sides, two stepping motors are electrically connected with the mouth of controller respectively, controller control step motor action makes the wheel of both sides be in parastate, and, when two-wheel car moving velocity is less than 15km/h, controller controls two stepping motor actions, make interlock seat length direction and two Connection Blocks perpendicular, when two-wheel car moving velocity is greater than 15km/h, controller controls two stepping motor actions, the angle between interlock seat length direction and Connection Block is made to become acute angle, and along with the increase of two-wheel car moving velocity, described sharp angle successively decreases, when two-wheel car moving velocity reaches 35km/h, the angle of acute angle is 45 °.
Described mount pad forms the joint pin be rotationally connected with Connection Block, torsion spring or elastic-like part is also installed between Connection Block and joint pin, torsion spring in the raw time, Connection Block and mount pad perpendicular.Such two wheels have certain rotational freedom, are beneficial to the speed that bipod controls two wheels respectively and realize keeping straight on or turning.When a wheel occurs to skid, because Connection Block and mount pad relatively rotate the restriction of angle and the existence of torsion spring, two-wheel car still can continue normal traveling under the driving of another wheel.As shown in Figure 2, on mount pad, the upper position of joint pin forms one in order to limit the retaining wall of Connection Block slewing area.
When two described Connection Blocks turn to parallel with the seat that links, between the end that two wheels are mutually close, leave gap.Like this when two-wheel car does not use, two wheels can turn to the side (Connection Block side fits with interlock seat side) of interlock seat under driving stepper motor, arrange handle, be beneficial to and carry two-wheel car in the middle of interlock seat.Described Connection Block is processed into L shape, and linking seat when such wheel is turned up can be bonded to each other with Connection Block.Magnet can be installed in interlock seat and Connection Block two surfaces of fitting or VELCRO or buckle etc. are connected and fixed.
Described mount pad is fixedly connected with the housing covering wheel top; Sensor described in two groups is fixed in described housing, and described controller is arranged in housing or links in seat; Described interlock seat or housing are provided with a spreading-retracting button be electrically connected with controller, when once pressing spreading-retracting button, controller controls two stepping motor actions, two Connection Blocks are made to be expanded to the seat that links perpendicular, when again pressing spreading-retracting button, controller controls two stepping motor actions, two Connection Blocks is turned to and fits with the seat that links.
When described pedal launches, its bottom near side, mount pad side to be against on mount pad thus to make pedal be positioned at horizontal direction, pedal upper surface described at least one is provided with inductive switch 20, inductive switch is connected with the signal input part of described controller, and described inductive switch is not trampled Time Controller and controlled wheel braking.When emergency situation, user jumps off from pedal like this, and inductive switch loss signal thus controller control wheel reversing immediately and realize braking.Described inductive switch is push type contact switch or switching regulator pressure sensor.
Be provided with storage battery in described interlock seat, storage battery is electrically connected with controller.Storage battery can form battery pack by 16 joint 18650 serial battery, two above-mentioned battery pack parallel connections can be used to use in order to increase flying power.
Often organize described sensor and include gyro sensor and acceleration pick-up, gyro sensor controller is controlled state of equilibrium that wheel fore-and-aft direction is in level, when body gravity deflection front or rear, controller is control torque motor forward or reverse correspondingly, when the amplitude of user's body forward, rear-inclined is larger, the side-play amount that acceleration pick-up detects is larger, then controller correspondingly control torque motor rotating speed increase.
The using method of this two-wheel car is similar to self-balancing wheelbarrow, and the center of gravity relying on user's health to act on wheel carrys out control rate.Before riding, because the inductive switch on pedal does not have signal, two-wheel car is standby, and after on user's both feet step on two pedals respectively, two-wheel car is just in by manipulation state, and then namely the center of gravity of adjustable health drives two-wheel car to move ahead.Two wheels are directly manipulated by bipod respectively, and alerting ability is strong, can realize flipper turn, and the technology that is suitable for good car fan use.
embodiment 2
The present embodiment, compared with embodiment 1, also comprises following characteristics:
Shown in composition graphs 3, described pedal is rotatably connected to a screw mandrel 22, be provided with a motor 21 in order to drive screw mandrel to rotate in pedal, described screw mandrel is connected by screw-driven with described mount pad; Described motor is electrically connected with a mouth of controller, when two-wheel car moving velocity is lower than 10km/h, motor driving screw mandrel rotates forward and pedal is moved to two-wheel car working direction front, when two-wheel car moving velocity is higher than 30km/h, motor driving screw mandrel rotates backward and pedal is moved to the rear of two-wheel car direct of travel.
When needing brake like this in higher speed driving process, because pedal is automatically moved to wheel rear positions, as long as user's health is swung back a little, center of gravity at once moves to wheel rear portion, can realize braking in time and ensure that user's amplitude of leaning back can not be excessive and cause falling down; When comparatively low speed driving, pedal is automatically moved to wheel forward position, and such user health that do not need to lean forward can keep two-wheel car low speed and at the uniform velocity travel, thus reduce shank firmly,
The top of two described pedals is separately installed with pressure sensor, and two pressure sensors are electrically connected with the input end of controller respectively; The difference of pressure recorded when two pressure sensors is less than 100N, two controllers control two wheel constant speed and advance, the difference of pressure recorded when two pressure sensors is greater than 100N, and the force value that two pressure sensors record is when being greater than zero, the wheel velocity of the larger side of controller control presssure is accelerated to realize turning.
The technical characteristic that the relative embodiment 1 of the present embodiment increases, make two-wheel car can conveniently keep keeping straight in ride, need the center of gravity shifting health significantly to drive during turning, applicable new hand or safety performance require that high user uses.
embodiment 3
