Abstract

A kind of electro-tricycle with clean boot function, including key switch, controller and motor M, the tricycle further includes the occupancy sensor being arranged in seat cushion interior, and the occupancy sensor is connected between key switch and controller, the operation of the controller control motor M.The utility model is arranged using occupancy sensor in seat cushion, when only rotating speed control crank simultaneously and sitting on cushion, electro-tricycle could be started, since children's figure is smaller, in the case where being supervised without adult, it can not simultaneously sit on cushion and rotate handle, effectively prevent the generation of " driving " contingency.

Description

A kind of electro-tricycle with clean boot function

Technical field

The utility model is related to a kind of electro-tricycles with clean boot function, belong to vehicle braking control technology neck Domain.

Background technology

Currently, electro-tricycle has become the indispensable vehicles in people's lives, existing electronic three All it is to open key switch when wheel vehicle starts, rotates handle, so that power unit is started, to realize the operation of tricycle.It is this Simple Starting mode has prodigious security risk, especially caused by children's maloperation personal injury just see repeatly not It is fresh.After parent stops electro-tricycle, due to carelessness, forgets to extract car key or forget the electric switch for turning off electro-tricycle Key, after causing child's maloperation, rotation speed control crank, electric vehicle, which is activated, causes " driving " accident, breeds a tragedy.

Utility model content

The utility model is directed to the drawback of the prior art, provides a kind of electro-tricycle with clean boot function, should The driving motor of tricycle is controlled using a controller, can effectively prevent error starting tricycle.

Problem described in the utility model is solved with following technical proposals：

A kind of electro-tricycle with clean boot function, including key switch, controller and motor M, the three-wheel Vehicle further includes the occupancy sensor being arranged in seat cushion interior, and the occupancy sensor is connected between key switch and controller, The operation of the controller control motor M.

The above-mentioned electro-tricycle with clean boot function, the controller include singlechip CPU, speed control crank, three Pole pipe T and relay J₁, the occupancy sensor is connected between the key switch and the speed control crank, and the speed governing turns The P for connecting the singlechip CPU_1.0Port, P_2.0Port connects the base stage of the triode T, the relay J₁It is three The load resistance of pole pipe, the relay J₁Normally opened contact connect the motor M.

The above-mentioned electro-tricycle with clean boot function, the seat cushion include face layer, elastic sponge layer and substrate, institute The setting of elastic sponge layer is stated between face layer and substrate, occupancy sensor is provided in the elastic sponge layer.

The above-mentioned electro-tricycle with clean boot function, the occupancy sensor are provided with one or two or three It is a, it is arranged in series between the occupancy sensor.

The above-mentioned electro-tricycle with clean boot function, the electro-tricycle further include motor work light LED, the motor work light LED are connected in parallel on the both ends the motor M.

The utility model is after adopting the above technical scheme, have the following technical effect that：

The utility model is only rotating speed control crank using the start and stop of occupancy sensor control electro-tricycle While, when human body is sat on cushion, and when body weight reaches occupancy sensor initially set threshold value, electricity could be started Dynamic tricycle.Since children's figure is smaller, speed control crank can not be rotated while sitting on cushion so that entire control circuit It is not turned on, to avoid children's maloperation from starting electro-tricycle.In addition, children's weight is lighter, occupancy sensor is not achieved The threshold value of setting, so as to avoid security risk caused by children's maloperation.

Description of the drawings

The utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is the control electrical schematic diagram of the utility model；

Fig. 2 is the utility model electricity principle control block diagram；

Fig. 3 is cushion structure schematic diagram.

Each list of reference numerals is in figure：1, key switch；2, controller；CPU, microcontroller；M, motor；T, triode；J₁, after Electric appliance；3, seat cushion；3-1, face layer；3-2, elastic sponge layer；3-3, substrate；4, occupancy sensor；5, speed control crank.

Specific implementation mode

Referring to Fig. 1~Fig. 3, the electro-tricycle with clean boot function includes key switch 1,2 and of controller Motor M, the tricycle further include the occupancy sensor 4 being arranged inside seat cushion 3, and the occupancy sensor 4 is connected on key Between switch 1 and controller 2, the controller 2 controls the operation of motor M.The occupancy sensor 4 be arranged in series there are one or Two or three, are connected in series between occupancy sensor.After opening key switch 1 with key, the human body of weight is only set It needs to be sitting on seat cushion 3, just can turn on occupancy sensor switch, while electro-tricycle entirely controls after rotating speed control crank 5 Circuit just can turn on, to start electro-tricycle, the generation of " driving " accident caused by effectively preventing children's maloperation.

The controller 2 includes singlechip CPU, motor M, occupancy sensor 4, speed control crank 5, triode T and relay J₁；The occupancy sensor 4 is connected between the key switch 1 and the speed control crank 5, and the speed control crank 5 connects described The P of singlechip CPU_1.0Port, P_2.0Port connects the base stage of the triode T, the relay J₁For the load of triode Resistance, the relay J₁Normally opened contact J_1-1Connect the motor M.

When work, if key switch is forgotten to extract, when children, which are sitting on vehicle seat, looks on the bright side of things dynamic tricycle, since its weight reaches Less than preset threshold value, microcontroller will not work, and motor will not rotate, and tricycle is motionless.Only when adult is sitting in On seat cushion, occupancy sensor 4 just can make triode ON by contacting, after singlechip CPU judges, the actuating of relay, Normally opened contact is connected, at this point, rotation speed control crank 5, connects circuit, motor M, which is powered, to be operated, and motor work light LED is bright, and three Vehicle is taken turns to start.

The output threshold value of occupancy sensor can prestore in microcontroller, just begin to be adjusted in advance according to driver's weight, Children are made to be unable to reach startup threshold value, so as to avoid security risk caused by children's maloperation.

In addition, when occupancy sensor is provided with two or three, since children's figure is smaller, can not be sitting in simultaneously two or On three occupancy sensors of person so that occupancy sensor contact is not turned on, and motor will not work, and avoids error starting electric three-wheel Security risk caused by vehicle.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change The scope of protection of the utility model is also should be regarded as into modification.
