Description
Technical field
The utility model is related to arrive pure electric automobile and special-purpose vehicle field, and in particular to be moved to a kind of electric traction vehicle electric
Towing pin.
Background technology
At present, the traditional towing pin applied in the market is mostly pure mechanic structure, mainly includes towing pin body and hand
Dynamic operation lever, driver control towing pin by operating manual lever, when tractor mounts trailer, also need ground staff
Cooperation mounting trailer, driver keep looking back to posture, hold the lifting for handle control machinery formula towing pin towing pin of stopping, simultaneously
Face staff is by the matched alignment of the hook of trailer.For being no less than the frequent operation of hundred times daily, add and drive
The labor intensity for the person of sailing easily causes shoulder neck to strain；Also waste of manpower simultaneously, loses time, the unmated tacit agreement of especially two people
When, the surface personnel that wounds when slipping up because moving backward easily is caused, is also susceptible to the accident for crushing surface personnel's finger.
The content of the invention
According to defect existing in the prior art, the utility model provides a kind of electric traction vehicle electric and moves towing pin, mainly
It is by the way that the important components such as towing pin mechanical part, stepping electric appliance, controller, camera of parking, display interface are collected
Into, and it is aided with electronic control logic, to realize that trailer mounts.
The specific technical solution of the utility model is：A kind of electric traction vehicle electric moves towing pin, including towing pin, stepping
Motor, controller, park camera and display, the towing pin are arranged on car body rear, control traction are set on towing pin
The stepper motor of lifting, the output axis connection towing pin of stepper motor are sold, the stepper motor connects controller, and controller is equipped with
Switch, switch are arranged in front of driver's cabin, and the car body rear sets camera of parking, and camera of parking connection display is shown
Show that device is arranged in front of driver's cabin.
Further, the output terminal connection bolt of the stepper motor, towing pin inner cavity are provided with screw thread, and stepper motor leads to
It crosses and is bolted towing pin.Stepper motor is by driving bolt rotation to realize the lifting of towing pin.
Further, the camera of parking is the far infrared camera with distance measurement function.
Further, top dead centre and lower dead center, stop of the lifting of the towing pin equipped with /V are by stepper motor
What controller was set, mainly realized by the way that motor is controlled to rotate revolution, when the revolution of motor reaches predetermined value, towing pin
Reach stop, no longer rise or fall.
Further, the switch is arranged in the switch enclosure with box cover, and switch enclosure is arranged in front of driver's cabin.
Beneficial effects of the present invention are：By one operation of driver, tractor is allowed effectively to be mounted with trailer, reach section
Human-saving saves money, and improves work efficiency, objectively reduces the occurrence probability of occupational hazards.
Description of the drawings
Fig. 1 is the tractor structure diagram with towing pin,
Fig. 2 mounts flow diagram for towing pin,
In figure：1st, towing pin, 2, stepper motor, 3, controller, 4, camera of parking, 5, display, 6, switch,
7th, towing pin.
Specific embodiment
The invention will be further described with reference to the accompanying drawings, and a kind of electric traction vehicle electric moves towing pin, including towing pin 1,
Stepper motor 2, controller 3, park camera 4 and display 5, the towing pin 1 are arranged on car body rear, are set on towing pin 1
Put the stepper motor 2 that control towing pin 7 lifts, the output axis connection towing pin 7 of stepper motor 2, the connection of stepper motor 2 control
Device 3 processed, controller 3 are equipped with switch 6, and switch 6 is arranged in front of driver's cabin, and the car body rear sets camera 4 of parking, and parks
Camera 4 connects display 5, and display 5 is arranged in front of driver's cabin.
Driver is instructed by Operation switch 6, issue control instruction to controller 3, the response of controller 3, and to stepping electricity
Machine 2 issues control instruction, promotes 7 liters of towing pin or drop on towing pin 1, in the process, camera 4 i.e. far infrared of parking
Camera can detect the size there are space and barrier automatically, be transferred information in real time in mounting process aobvious on instrument desk
Show device 5, driver is by observing the information on display 5, judging and implementing 7 descending operation of towing pin.
One section of bolt is connected on 2 one output terminal of stepper motor, 7 inner cavity of towing pin is really threaded elongated " nut ",
Stepper motor 2 is by driving bolt rotation to realize the lifting of towing pin 7.During work, towing pin 7 is by screw thread guiding come up and down
It is mobile.
The lifting of towing pin 7 on towing pin 1, there is provided upper and lower two stops, stop is by the controller of stepper motor 2
3 settings, mainly realized by the way that motor is controlled to rotate revolution, when 7 lifting process of towing pin reaches any stop, control
The phenomenon that device 3 processed is issued /V and is instructed to stepper motor 2, and dieback or drop when are declined by less than when being not in liter,
Prevent invalid mounting.
The controller 3 connects display 5, if towing pin 7 during moving up and down, is acted on accidental stuck existing by external force
As the controller 3 of stepper motor sends overload protection information, and overload protection information is directly fed back on display 5, and prompting is driven
The person of sailing is adjusted operation, prevents invalid mounting.
Switch when driver is lifted by 6 operation towing pin 7 of switch, to prevent maloperation, is placed in one by incorrect switching
In a switch enclosure that can be opened and close, just have to first open switch enclosure cover when needing Operation switch, it is dynamic by two
Work could complete an operation.
Vehicle realizes that is, vehicle is opened by controller 3 in the process of movement, switch limitation operation, this limitation
Dynamic, controller is stopped, and controller voluntarily starts during parking.Effectively prevent because in driving conditions, maloperation and there is trailer
The unsafe condition departed from tractor.
The control method of electric traction bolt, comprises the following steps：
Step 1：Tractor is moved to and stopped when mounting trailer position, and controller starts during parking；
Step 2：Detection is there are space and the size of barrier automatically for camera of parking, in mounting process in real time by information
The display being transferred on instrument desk, driver adjust vehicle location by the information on display and carry out mounting pre- aiming；
Step 3：Driver is by observing the information Operation switch on display, and issue control instruction is to controller；Control
Device receives instruction, and control instruction is issued to stepper motor, and stepper motor drives towing pin liter or drop on towing pin, to hanging
Vehicle is mounted；
Step 4：After the completion of mounting, tractor starts, and controller is stopped.
Wherein, plate structure subject to mechanical traction bolt, is processed using welding procedure, and hole position is using common machining；
Stepper motor uses 12V, stroke 115mm, torque 12kg.cm, screw M10, length 182mm, and rotating speed 5 encloses the/second；Above and below towing pin
Mobile once stepping motor rotating shaft need to rotate 11.5 circles, and run duration is 2.3 seconds, and the operation for meeting people receives the time；Controller
The protection level requirements of IP67 need to be reached；The device is particularly suitable for the matching of special place vehicle and related special vehicle, such as machine
Field luggage tractor, logistics tractor etc..
