Description
Technical field
Electric automobiles are the utility model is related to, especially a kind of old tricycle.
Background technology
At present, do not specialize in electric bicycle or electro-tricycle that the elderly uses, conventional electric bicycle or
Person's electro-tricycle when turning or running into barrier can not automatic retarding, the control of speed must carry out manually, and
The agility of the elderly is poor, it is not easy to carries out deceleration-operation in advance when turning or running into barrier, security risk is larger.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of old tricycle, can be anti-according to the instinct of human body
It should slow down, it is not necessary to it is specially manually operated, make the elderly safer when riding.
Technical scheme is used by the utility model solves its technical problem：Old tricycle, including vehicle frame, the car
The head of frame is provided with key switch, and middle part is provided with power supply, and rear portion is provided with motor and power transmission shaft, the motor and transmission
Axle is connected, and the power supply, key switch and motor are connected in series；
Also include a pair of pedals, rotating shaft, pivot sensor, controller and electric-controlled switch, the rotating shaft and car
Frame is rotatably assorted, and the pedal is fixedly installed in the both ends of rotating shaft, and the pivot sensor is used for whether detecting rotating shaft
Rotate, pivot sensor, controller and the electric-controlled switch are connected with power supply, the electric-controlled switch and controller phase
Even, the electric-controlled switch, key switch and motor are connected in series.
Further, the pivot sensor uses absolute value encoder, speed probe and Hall sensor
In one kind.
Further, the motor is connected by chain with power transmission shaft.
Further, the electric-controlled switch is electromagnetic switch.
Further, the rotating shaft is connected by chain with power transmission shaft.
The beneficial effects of the utility model are：When above there is barrier or needing to turn, the natural reaction of human body
It is off stepping on pedal, now, rotating shaft stops operating, and pivot sensor is used to detect whether rotating shaft rotates, and will inspection
The signal measured is transferred to controller, and when rotating shaft stops operating, controller control electric-controlled switch disconnects, and motor power-off stops turning
It is dynamic, tricycle decelerating turn or deceleration straight-line travelling in the presence of inertia, with ensure turning security or before barrier and
When stop.This tricycle, it can be slowed down according to the natural reaction of human body, it is not necessary to it is specially manually operated, when the elderly is ridden
It is safer.
Brief description of the drawings
Fig. 1 is vertical view partial schematic sectional view of the present utility model；
Fig. 2 is circuit connection diagram of the present utility model.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, old tricycle of the present utility model, including vehicle frame 1, the head of the vehicle frame 1 are provided with
Key switch 2, middle part are provided with power supply 3, and rear portion is provided with motor 4 and power transmission shaft 5, and the motor 4 connects with the transmission of power transmission shaft 5
Connect, the power supply 3, key switch 2 and motor 4 are connected in series；
Also include a pair of pedals 6, rotating shaft 7, pivot sensor 8, controller 9 and electric-controlled switch 10, described turn
Axle 7 is rotatably assorted with vehicle frame 1, and the pedal 6 is fixedly installed in the both ends of rotating shaft 7, and the pivot sensor 8 is used to examine
Survey whether rotating shaft 7 rotates, the pivot sensor 8, controller 9 and electric-controlled switch 10 are connected with power supply 3, the electricity
Control switch 10 is connected with controller 9, and the electric-controlled switch 10, key switch 2 and motor 4 are connected in series.
Vehicle frame 1 includes handlebar, seat, wheel etc., can use existing arbitrary structure.Key switch 2 is arranged at queues of stationary traffic
On head, power supply 3 is used to power for each electronic component, and power supply 3, pivot sensor 8 and controller 9 are arranged at under-seat
Mounting box body in, power supply 3, power transmission shaft 5, key switch 2 and motor 4 use prior art, the pivot sensor 8
One kind in absolute value encoder, speed probe and Hall sensor can be used, these sensors can detect rotating shaft
Rotating speed, judge whether rotating shaft 7 is rotating according to rotating speed.Controller 9 not only can use using the controller of general battery truck
, can be with startup, stopping, deceleration of controlled motor 4 etc. in the break-make of control electric-controlled switch 10.At present, controller 9, automatically controlled open
Closing 10, absolute value encoder, speed probe and Hall sensor, maturation is applied to every field, and it is new to implement this practicality
During type, the finished product of suitable types is bought.Preferably, the electric-controlled switch 10 uses electromagnetic switch.
Ride this tricycle when, first with key unlocking key switch 2, now, rotating shaft 7 is static, and electric-controlled switch 10 disconnects,
Motor 4 is in off-position, and tricycle will not travel, and after waiting driver to occupy stably, steps pedal 6, and rotating shaft 7 rotates, rotating shaft fortune
Dynamic sensor 8 detects that the rotating speed of rotating shaft 7 is more than 0, transmits signals to controller 9, and controller 9 controls electric-controlled switch 10 to close
Close, motor 4, which is powered, to be rotated, and drives power transmission shaft 5 and the vehicle wheel rotation at the both ends of power transmission shaft 5.Rotating shaft 7 is installed on vehicle frame by bearing
1, it is only necessary to which applying the power of very little to pedal 6 just can be such that pedal 6 persistently rotates, and ride laborsaving.When need turn or
When barrier occurs in front, driver stops stepping on pedal 6, the stop motion of rotating shaft 7 by the light of nature, and pivot sensor 8 is examined
The rotating speed for measuring rotating shaft 7 is 0, transmits signals to controller 9, and controller 9 controls electric-controlled switch 10 to disconnect, and the power-off of motor 4 stops
Machine, tricycle run out of steam, and decelerating turn or deceleration move forward, and ensure the safety of driver.
The motor 4 is connected by chain 11 with power transmission shaft 5.
In order to further mitigate the burden of driver, the rotating shaft 7 is connected by chain 11 with power transmission shaft 5.Normal row
After sailing, driver need not exert oneself, and power transmission shaft 5 drives rotating shaft 7 to rotate by chain 11.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all in the spirit and principles of the utility model
