The specific embodiment
As shown in Figure 1, in an embodiment of the present utility model, electric golf cart comprises joystick 1, front-wheel 2, front fork 3, strut bar 4, two trailing wheels 5 and control circuits.
In running condition, setting tilts after descending before strut bar 4 is.The bottom front end of strut bar 4 is provided with a baffle plate 401, and top and middle and lower part are provided with the club fixed mount respectively.Baffle plate 401 is connected with strut bar 4 by rotating shaft 402, and in running condition, baffle plate 401 is fixed on the position rectangular with strut bar 4 by supporting piece, thereby the golf club bag can be resisted against on the baffle plate 40 1, and by the club fixed mount club bag is fixed; When not using, baffle plate 401 can be turned to collapsed position towards strut bar 4.The middle part of strut bar 4 is connected with two rear wheel fulcrum bars 403 by rotating shaft, and links to each other with two trailing wheels 5 respectively by rear wheel fulcrum bar 403.Also be provided with the trailing wheel pull bar 404 of two rigidity on strut bar 4, an end of trailing wheel pull bar 404 is fixed on the front side portion of strut bar 4, and the other end is articulated in fixedly buckling on 405 of rear wheel fulcrum bar 403.Also be provided with folding and buckle 406 on the appropriate location that fixedly buckles the strut bar 4 above in the of 405, when trailing wheel pull bar 404 is articulated in when fixedly buckling on 405, rear wheel fulcrum bar 403 is fixed, and golf cart is in open mode; When trailing wheel pull bar 404 is articulated in folding when buckling on 406, rear wheel fulcrum bar 403 can rotate around the axis to collapsed position.The lower end of strut bar 4 is connected with front fork 3 by vertical rotating shaft 6, and by vertical rotating shaft 6, front fork 3 and front-wheel 2 can freely turn to by relative strut bar 4 in 360 ° of scopes of horizontal surface.
Joystick 1 is a hollow stem, comprises two parts up and down that are connected by arrangement for adjusting height 11, before running condition is on after the setting that has a down dip.The top of joystick 1 is provided with handle 12 and scoring board 13, and the bottom of joystick 1 and front fork 3 fix.As shown in Figure 2, arrangement for adjusting height 11 comprises the axle sleeve 102 that is connected with joystick top, and the connecting strap 107 that is connected with the joystick bottom; In axle sleeve 102, be respectively arranged with friction plate 101 and 104, be provided with compression spring 103 between the friction plate 101 and 104 with connecting strap 107 contacted both sides; Connecting strap 107 inner surfaces, friction plate 101 and 104 and connecting strap 107 contacted surfaces be equipped with lines, required static friction force when producing the location; Axle sleeve 102 is connected with captive nut 106 by the screw rod 105 that wears thereon with connecting strap 107.When by handle 12 application of forces of joystick 1, joystick top overcomes the friction force between friction plate and the connecting strap and rotates, so that the stepless any adjustment of the height of joystick 1, thereby is fit to the personage of different heights; When stopping the application of force, because the elastic force effect of compression spring 103, friction plate and connecting strap compress mutually, produce static friction force, make joystick 1 location; When not using, can make the top of joystick 1 turn to collapsed position by bar handle 12 to strut bar 4.Both sides in joystick 1 bottom also are respectively arranged with tension spring 12, and an end of tension spring 12 is fixed on the lower side of joystick 1, and the other end is fixed on the lower side of strut bar 4.Because joystick 1 fixes with front fork 3, and is provided with rotating shaft 6 between front fork 3 and the strut bar 4, can golf cart be turned to by the application of force on joystick lever 12; After forcing the power that turns to disappear, under the effect of tension spring 12, can make front-wheel 2 reply the direction of keeping straight on.
As shown in Figure 3, front-wheel 2 is to adopt rotor to be set in the exterior hub-type motor of stator to make.The hub-type motor is stator with center shaft 21 with being fastened on center shaft 21 exterior windings 22, is rotor with the shell 24 that permanent magnet 23 is housed, and is connected by bearing 25 between stator and the rotor.The bottom of joystick 1 fixes by the two ends of front fork 3 with the center shaft 21 of stator, and the circuit pig-tail wire contact 26 of motor is arranged on center shaft 21 ends.The wheel hub of the front-wheel 2 of electric golf cart is to be made by rotor, can directly encapsulate engineering plastics 27 or industrial rubber by the rotor outside at the hub-type motor, air-inflation tyre also can be installed form.
The control circuit of electric golf cart mainly comprises control button, hub-type motor 2, controller 7, storage battery 8 and lead.Control button is arranged on the handle 12 of joystick 1, controller 7 is arranged on the back side of strut bar 4 front ends, storage battery 8 is arranged on strut bar 4 back sides of controller 7 tops, and storage battery 8 can adopt lead-acid battery or Ni-MH battery, and its charging socket is arranged on the controller 7; The lead of control button is directed to controller 7 through the central cavity of joystick 1, and the circuit pig-tail wire of hub-type motor 2 is directed to controller 7 through front fork 3, thereby forms the control circuit loop.As shown in Figure 4, the control circuit of electric golf cart is to improve to form on the basis of general-duty brushless motor control circuit, controller 7 wherein is that the model that adopts Motorola Inc. to produce is the control chip of MPU33035, the difference of itself and general control circuit is, utilize the electricity generating principle of motor itself, draw the sensor current signal end from two winding A, C of three phase electric machine, a speed-regulating signal input end of input controller is to form the sensor circuit signal deteching circuit after photoelectrical coupler is handled.When motor is dragged by the people or in rotary course, all can produce sensor current signal, the speed-regulating signal input end of input controller is as the actuation signal of controller after photoelectrical coupler is handled, controller is only when detecting this actuation signal, just connect working current, like this problem of the excessive easy damage motor of starting current when having avoided that motor is static to be started; On the other hand, if motor does not also have in entry into service or the operation process by the external force forced brake, i.e. this sensor current signal not, then controller stops immediately to the motor power supply, thereby prevents motor rotation blockage, prolongs motor service life.Because controller 7 has the commutation and the function of speed governing, can pass through the control button switch motor hand of rotation at any time on the handle 12, controlling advancing or falling back of car body easily, and advance to carry out infinite speed variation in the process in ball garage.
