Abstract

A driving device for body-building and riding comprises a trapezoid connection rod mechanism, a pair of front and back stand bars, a pedal, a wheel, and a braking clip. A sliding rod and a spring are positioned among the connection rods of the trapezoid connection rod mechanism. The connection rods are movably connected together. The bottom of the front and the back stand bars are provided with wheel frames, whereon the wheel and the braking clip are arranged. When in riding, foot stamping and self weight enable the driving device to imitate the fluctuating movement of animals to operate. The device has simple structure and low cost of production, the advancing speed can be controlled at will, saves operational labor and is applicable for children to ride.

Description

Body-building drives drive unit

The utility model relates to a kind of body-building and drives drive unit, especially relates to a kind of children of confession body-building and drives proal drive unit.

The driving method of present manned walking machine generally adopts manpower and electronic two kinds of modes.This dual mode is that simple level travels forward, and can not imitate the dipping and heaving action that produces in the animal movement, lacks authenticity and enjoyment, and these two kinds of driving device structures are complicated, and the manufacturing cost height is difficult in maintenance.

The purpose of this utility model is to provide a kind of mechanical device, makes drive unit can significantly imitate animal motion in the dipping and heaving action.

The purpose of this utility model is achieved in that drive unit, it comprises a trapezoidal linkage, before paired respectively, rear leg, a pair of is foot-operated, 4 wheel carriers and wheel braking card, in the middle of the neighbouring connecting rod of described trapezoidal linkage, be provided with spring, between the neighbouring connecting rod of described trapezoidal connecting rod slide bar is housed, connecting rod in the described trapezoidal linkage and connecting rod flexibly connect, before described, the upper end of rear leg be separately positioned on described before trapezoidal linkage lower link before, the rear end, before described, the bottom of rear leg is provided with wheel carrier, wheel is equipped with in described wheel carrier lower end, described braking clamp top is fixedly mounted on the upper end of described wheel carrier, and its underpart combines with described wheel lower end from hanging down.

Advantage of the present utility model is that it has adopted trapezoidal linkage, make full use of the effect that body weight and pin are stepped on, the progressive action of imitation animal, especially run on one's body as riding over animal, bring a lot of enjoyment for the saddle horse person, and in amusement, accept physical exercise, can strengthen people's waist, leg, limb force, and more laborsaving when using, can be for the usefulness of children's body-building recreation.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the front view of the utility model drive unit;

Fig. 2 is the schematic diagram that is similar to Fig. 1, wherein shows another embodiment of the present utility model;

Fig. 3 is the zoomed-in view of wheel subdivision among Fig. 1;

Fig. 4 is the generalized section of Fig. 3.

Now referring to Fig. 1,2 and 3,4, drive unit of the present utility model comprises trapezoidal linkage 17, front support leg 7, rear leg 8 and a pair of foot-operated 16,4 wheel carriers 18 and wheel 9, braking clamp 10 in pairs in pairs.Ladder type bar linkage structure 17 is by load-bearing connecting rod 1, and side connecting rod 2,3 is connected by removable pin 6 respectively with lower link 4,5, forms a five-bar mechanism like this.Between the side connecting rod 3 of ladder type linkage and lower link 4, be provided with an arcuate struts 15, play the role of positioning, arcuate struts 15 lower ends are fixed on the lower link 4 and pass side connecting rod 3 on it and stretch out trapezoidal linkage 17, arcuate struts 15 sheathed springs 13 between side connecting rod 3 and lower link 4, also sheathed another spring 14 on the over-hang part of arcuate struts 15, spring 13,14 work folding amplitude and the return effect regulated.Be provided with a vertical slide bar 11 in addition between load-bearing connecting rod 1 and lower link 5, vertical slide bar 11 upper ends are fixed on the load-bearing connecting rod 1 and its lower end is passed lower link 5 and stretched out trapezoidal linkage 17, and vertical slide bar 11 can be controlled balance.Between the load-bearing connecting rod 1 of trapezoidal linkage 17 and lower link 4,5 spring 12 is set, spring 12 helps trapezoidal linkage 17 to reset in distortion.Be equipped with a pair of foot-operated 6 at lower link 4, the upper end of forward and backward leg 7,8 is fixedly installed on the two ends of lower link 4,5 respectively, wheel carrier 18 is installed in bottom at forward and backward leg 7,8, wheel 9 is equipped with in wheel carrier 18 lower ends, braking clamp 10 tops are installed on wheel carrier 18 upper ends, braking clamp 10 bottoms are free sagging in the lower surface of wheel 9, and the friction that braking clamp 10 utilizes wheel 9 backs to change is finished the location to wheel 9, guarantees that 9 on wheel stands fast forward.

The motion process of this drive unit is, when the people rides on the bearing bar 1, after pin is placed on foot-operated 16, because people's self-gravity action on bearing bar 1, makes trapezoidal linkage 17 keep compressive state, promptly load-bearing connecting rod 1 is mutually close with lower link 4,5, side connecting rod 2,3 is close to lower link 4,5, spring 13 is pressurized slightly, forward and backward leg 7,8 one-tenth plumbness, lower link 4,5 one-tenth parallel shapes.When the people firmly pedal step on foot-operated 16 the time, this moment, people's buttocks left load-bearing connecting rod 1, lower link 4,5 and load-bearing connecting rod 1 space out, spring 14 pressurizeds, spring 12 elongates, and lower link 4,5 is deformed into V-type downwards, front support leg 7 is to front slide like this, and the braking clamp 10 that is positioned on rear leg 8 is lived wheel 9 surely and must not be rotated backward, and at this moment forward and backward leg 7,8 spaces out and becomes Eight characters shape, and whole device has a declining tendency.Again because after the people abandons power foot-operated 16, the people acts on bearing bar 1 again from gravity, makes lower link 4,5 recover parastate, and rear leg 8 is close to front support leg 7 simultaneously, the braking clamp 10 that is positioned on front support leg 7 is lived wheel 9 surely and must not be rotated backward, and whole like this device is just stepped out a step forward.Reciprocal so like this, whole device is travelled forward.Help return because spring 12,13,14 has been installed again, so the power of human is less, children also can use.And whole device falls suddenly at the volley and neglect to rise, and just produced the dipping and heaving effect of imitation animal forward motion.
