Description

Multifunctional body-building tricycle for children

The utility model is a kind of multifunctional body-building perambulator, belongs to non-motor-driven child car.It can be used as children's such as family, kindergarten, primary school, recreation ground body-building, the equipment of playing, competing.

Its external form of various perambulators in the market is similar, function is few and single, still traditional common style with both feet driving car body easy motion; And along with the growth of child age, car just can't use, and causes the perambulator purposes little, and children do not have novel sense.

Main purpose of the present utility model is to provide 3～9 years old all spendable perambulator of each age children solves body building and travels in the problem of the multiple function of one.

Specific design measure of the present utility model is: when using out of doors, child rides onboard both feet and is placed on the front-wheel direction control bracket plate and controls direction of traffic, two-hand control headstock place hand exercise mechanism, make car body such as horse run formula ground undulatory motion by the two-stage driving system, car can move forward or backward.Can temper the strength of children's hand and buttocks, strengthen the motor function of internal organ.When indoor use, car placed make on the special-purpose vehicle frame that car body can not seesaw, sit hand exercise mechanism and leg exercise mechanism are carried out individually or simultaneously; The sense of motion of hand and leg can be in the same way or counter motion, and the size of leg exercise amount can be regulated.To reach the flexibility ratio that improves each joint part, promote the growth of brain control, balance, the coordination ability, strengthen effects such as children's muscle power.Two sides, the left and right sides, headstock support top as the drive sprocket outer cover, is equipped with the electronic simulation voice activated control with different animal head types in the cover, the cry that can send imitative animal at any time replaces common small bell, feels very novel and happy when allowing children play.The seat cushion bottom of car is provided with tunable arrangement, can regulate the position of seat cushion forward or backward, up or down, makes 3-9 year children easy to operate, ride sit suitable.In a word, the utility model has been realized purpose of the present invention in the function design.

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail:

Concrete structure of the present utility model is made up of seven parts such as hand exercise mechanism, driving system, body movement mechanism, leg exercise mechanism, seat cushion regulating mechanism, headstock head sprocket outer cover and electronic simulation voice activated control.

Fig. 1 is an overall schematic of the present utility model.

Fig. 2 is headstock head sprocket outer cover of the present invention and voice activated control scheme drawing.

Fig. 3 is the special-purpose vehicle frame scheme drawing of this perambulator.

As shown in Figure 1:

One, hand exercise mechanism: form by headstock bracket component (2), Handleset (3).The upper end of the vertical hollow steel pipe in front of the bottom of headstock support (2) and chassis assembly (5) is connected into one with the Luo bolt, the mandrel of Handleset (3) is gone up fork with headstock support (2) and is connected with the pellet shot from a slingshot bearing, drive sprocket (1) is fixed on the mandrel, drive head sprocket (1) when handle rotates and just doing together or counter-rotation, drive to move by driving system.

Two, driving system: form by the driven sprocket (9) on drive sprocket (1), preceding chain (4), middle transition duplex chain wheel (14), rear chain (11), the hind axle (10).Head sprocket (1) is just being done or during backward rotation, is being driven chain (4) and be synchronized with the movement, and makes duplex chain wheel (14) also do in the same way rotation synchronously; Rear chain on it (11) drives driven sprocket (9) and is fixed in rear vehicle shaft (10) the do rotation synchronously in the same way of one, and the power of hand exercise is delivered on the hind axle (10) by the two-stage chain drive system, and car body produces motion.

Three, body movement mechanism: form by chassis assembly (5), back eccentric vehicle wheel component (8), rear vehicle shaft (10), pre-eccentric vehicle wheel component (16), foot control direction bracket component (15).Chassis assembly (5) wherein: be welded with foot-operated mandrel lug through hole support and extension spring pole by the middle part of two duplex chain wheel supports of the oblique crook welding of the cushion rack of the back upper place welding of the preceding vertical hollow steel pipe of the front end welding of two vehicle frame main beams, beam, beam, beam, beam and collude etc. and to be welded.Eccentric wheel after two (8) is integral with the Luo bolt is affixed with rear vehicle shaft (10); The back vent of two cross member of framees connects with the pellet shot from a slingshot bearing with hind axle (10), can relatively rotate neatly; The upper shaft of foot control direction bracket component (15) connects with double-deck (about spacing 120mm) pellet shot from a slingshot bearing with the preceding vertical hollow steel pipe of assembly (5), and the foot control support can steadily and neatly be rotated around preceding vertical hollow steel pipe; Foot control bracket component (15) lower end yoke connects with the pellet shot from a slingshot bearing with the wheel shaft of pre-eccentric vehicle wheel component (16), and the pre-eccentric wheel can be rotated around the lower end of foot control support (15) yoke flexibly and reposefully.Energy heave and set ground such as horse move forwards or backwards with running formula when making body movement by three accentric wheels.

Four, leg exercise mechanism: form by foot-operated assembly (13), adjustable spring (12).The mandrel of foot-operated assembly (13) is interspersed in two main beam lug rack ventilating holes of chassis assembly (5), foot-operatedly makes positive and negative direction and freely rotate with pin is affixed with mandrel.Be with the rubber bush of slack running fit in the middle of the mandrel, the through hole and extension spring (12) the one end hook joints of its sleeve middle part lug, extension spring other end hook joint make when riding the mandrel rotation and rubber bush inwall generation frictional resistance on arbitrary the colluding that vehicle frame pole is colluded.Foot-operated strength size of rotating is colluded far away, the nearly hook that colludes car beam pole by extension spring (12) and is regulated.

Five, seat cushion regulating mechanism: form by seat cushion upper-lower position adjusting part (6), front and back position adjusting part (7), spring seat cushion assembly.Tighten thick steel pipe above the elongated slot of the cushion rack of vehicle frame and be integral by big mother Luo in the assembly (7), this steel pipe bottom is welded a flat gasket and is contacted below elongated slot, when mother Luo unclamps this pipe and seat cushion together can be in elongated slot forward or move backward to the desired position.Also can move up and down in the thick steel pipe of the little steel pipe plug-in package (7) of assembly (6), after little steel pipe is transferred to suitable height, the Luo select on the assembly (6) be tightened, pipe clamp becomes one assembly (6) and assembly (7).

As shown in Figure 2: the outer cover of headstock support of the present utility model top head sprocket, form by the left side (17), (18) two on the right.Outer cover is loaded on the right and left on headstock support (2) top with screw, each imitative a kind of animal head type of two outside faces of outer cover, can adopt punching press plate or moulding all can, its overall dimensions size is all identical.Electronic simulation acoustic control wiring board (19), patch (20), battery (21), acoustic control knob (22) etc. are housed in the cover.

As shown in Figure 3: special-purpose vehicle frame of the present utility model (23), can make car two trailing wheels when indoor use revolve sky, vehicle frame two crossbeam back vents place on the vehicle frame, and car body can be as you were when motion for hand and pin.
