Specific embodiment
Below in conjunction with the accompanying drawings the present invention will be further described with specific embodiment.
As shown in Figure 1, a kind of rocking toy car for being easy to children to use, including one can on the ground before and after arc swinging vehicle frame 1, vehicle frame adopts splicing construction, specifically include the base plate 11 of a circular arc evagination, it is vertically situated at the riser 12 of the left and right sides of base plate, and the cover plate 13 being connected across on two pieces of risers, the both sides up and down of riser are respectively by least two connecting elements and cover plate lower surface, and plate upper surface forms T-shaped being fixedly connected, riser therein constitutes the straight to sheet material portions of T-shaped connection, and cover plate and base plate then constitute the horizontal sheet material portions of T-shaped connection, each sheet material of vehicle frame can be made using density board, and cover plate is then a compressing curved slab, certainly, in order to increase comfortableness, we can lay the cushion of softness on rear side of cover plate, so as to become seat cushion.In order to reduce the contact area of vehicle frame and ground, the left and right sides of base plate are respectively equipped with the arc flange 14 for being higher by plate outer surface, and the lower limb of the arc flange of both sides is located at same arc surface, so as to constitute a circular arc bottom surface.Additionally, the rigidity and intensity in order to increase vehicle body, riser can slope inwardly from the bottom to top setting, specifically, between riser and base plate the angle of inner side between 80 degree to 85 degree so that the cross section of vehicle body is substantially trapezoidal.
In addition, as shown in Fig. 2 the front cross in vehicle frame a final drive shaft 5 is set, the two ends of the final drive shaft are respectively provided with bearing block, and bearing block is fixed on the left and right sides riser of vehicle frame, so that final drive shaft is rotatable.Also, we need to be fixedly connected a vertical drive link 6 in the centre position of final drive shaft, the upper end of the drive link upwardly extends and passes the cover plate of vehicle frame, certainly, the slip groove 134 that a longitudinal direction is set is needed on the cover plate of vehicle frame, so that drive link is slidably positioned in slip groove, drive link stretches out the upper end of cover plate and arranges corresponding handrail 2, so that the children rided on vehicle frame can make drive link along slip groove swing by pulling handrail, and final drive shaft is correspondingly driven to carry out back rotation.Further, we need to also connect a horizontal step 7 in the lower end of drive link, so that occupant drives step swing by both feet, and then drive drive link swing.Specifically, step includes being connected to the cross bar 71 of drive link lower end in T shapely, and the riser of the vehicle frame left and right sides is stretched out at the two ends of cross bar, while each autorotation in left and right both ends in cross bar connects a pedal 72.It is understandable that, we need to arrange arc-shaped slot 121 on the riser of the left and right sides, cross bar is slidably positioned in arc-shaped slot, and the radius of arc-shaped slot should be equal with the distance of cross bar to final drive shaft, so that cross bar can be moved back and forth along before and after arc-shaped slot.
Especially, medium position of the present invention in vehicle frame laterally arranges a secondary power transmission shaft 8 parallel with final drive shaft, and the two ends of this power transmission shaft are also respectively provided with the bearing block on the left and right sides riser for being fixed on vehicle frame, so that secondary power transmission shaft is rotatable.Swing arm 81 straight down is set on secondary power transmission shaft simultaneously, and the lower end of swing arm then arranges a pendulum 82.So, as long as we arrange corresponding transmission mechanism between primary and secondary power transmission shaft, you can make primary and secondary power transmission shaft form association.When occupant pulls with hand handrail, drives final drive shaft to rotate with pedal pedal, you can make time drive axis, and drive swing arm to make pendulum swing.It is understood that transmission mechanism can be using various ways such as existing Chain conveyer, gear drive, pulley drives.In the present embodiment, transmission mechanism adopts gear drive, specifically, transmission mechanism includes the driving gear 91 being arranged on final drive shaft, the driven gear 92 being arranged on time power transmission shaft and the two-sided rack 93 being arranged between driving gear and driven gear, the upper and lower surface of the two-sided rack is respectively provided with engaging tooth, it is meshed with driving gear above the two-sided rack, is then meshed with driven gear below the two-sided rack.
Children when hand-car is taken, can both hands get a grip on the rail, bipod is then stepped down on pedal, to keep the balance of body and hand-car.When body hypsokinesis, move after the center of gravity of body and the shaking moment of one swing backward of generation, now both hands pull back handrail naturally, and both legs are then extended straight forward naturally, so as to promote drive link to rotate in perpendicular.Drive link then drives final drive shaft to rotate, and then drives time drive axis by driving gear, the two-sided rack, driven gear.Because driving gear and driven gear are meshed respectively with the upper and lower surface of the two-sided rack, therefore, the rotation direction of secondary power transmission shaft and final drive shaft is conversely, and then drive pendulum synchronously swing backward.So, the shaking moment of hand-car swing backward is further increased on the basis of hand-car overall weight is not changed, and correspondingly reduce resistance torque, enable hand-car soon swing backward.On the contrary, when body forward is inclined, both legs bend contraction naturally, and both hands then protract to promote drive link to rotate backward naturally.So, the position of centre of gravity of children's torso and pendulum is moved forward simultaneously, hand-car is soon swung forward.Make hand-car be rapidly introduced into swinging condition by so moving in circles, and correspondingly improve the hunting frequency of hand-car.
It should be noted that, we can be respectively provided with slide rail 94 in the medial surface of left and right riser, and the rear and front end of the two-sided rack is then respectively provided with horizontal support shaft 95, the two ends of support shaft arrange the roller adapted in slide rail, so that the two-sided rack is reliably supported, and can be movable along slide rail.
Both sides are symmetrically arranged accumulating mechanism 10 before and after we can also be located at pendulum in vehicle frame, accumulating mechanism includes being fixed on vehicle frame and the slide cartridge 101 of one end open, the lance 102 that is slidably arranged in slide cartridge, the slide cartridge openend of former and later two accumulating mechanisms is relative, outer end on lance towards pendulum then arranges the anticollison block 103 of hard, and spring 104 is arranged between the Inner ends and the bottom surface of slide cartridge of lance.So, when pendulum swing is to certain position, you can collide with anticollison block, and then make lance overcome the resistance of spring to compress into slide cartridge, to play a cushioning effect to pendulum, it is to avoid the impact occurred during its backswing.And pendulum relies on the elastic force rapidly backswing of spring after its extreme position is reached, so that hand-car is rapidly formed an extra resistance torque when the extreme position of side is swung to, hand-car now is promptly decelerated to zero and starts backswing, so as to be conducive to improving the hunting frequency of hand-car.It is understood that anticollison block should be located on the swinging track of pendulum, in order to the collision of pendulum and anticollison block.
In order to position the angle between riser and base plate and cover plate exactly, as shown in Figure 3, Figure 4, the connecting elements of the present invention includes the universal coupling assembly 3 for forming T-shaped connection and the angular adjustment component 4 for controlling the angle of T-shaped connection.Universal coupling assembly therein includes connection U-shaped cutting ferrule 31, the connection core ring 32 fitted in connection U-shaped cutting ferrule and the support shaft 33 being connected in connection core ring, support shaft connects a U-shaped buckle 34 away from one end of connection core ring, and on the relative side wall of the U-shaped buckle two screw via is respectively provided with.The lateral surface of connection U-shaped cutting ferrule is the face of cylinder, and medial surface is then sphere, correspondingly, connect the sphere that core ring lateral surface is and is connected U-shaped cutting ferrule medial surface adaptation, so that connection core ring is in cydariform small in ends, broad in the middle, so, support shaft both can be rotated by connection core ring in connection U-shaped cutting ferrule, swing can be formed simultaneously, and connect core ring will not deviate from from connection U-shaped cutting ferrule.Connection core ring is installed in connection U-shaped cutting ferrule for convenience, such as Fig. 5, shown in Fig. 6, we can along the circumferential direction decile arranges two insertion grooves 311 on the end face of support shaft on connection U-shaped cutting ferrule, that is, two insertion grooves now are located at connection U-shaped cutting ferrule end face diametrically, the width of insertion groove should be greater than connecting the height of core ring, insertion groove is along the axially extending until tangent with the medial surface for being connected U-shaped cutting ferrule of connection U-shaped cutting ferrule, it is understandable that, the lateral surface of insertion groove should be the face of cylinder, and its diameter should be identical with the spherical diameter of connection U-shaped cutting ferrule medial surface.So, when needing that connection core ring is installed in connection U-shaped cutting ferrule, the axis and the axis perpendicular for being connected U-shaped cutting ferrule of connection core ring can be made, then connection core ring can be vertically filled in insertion groove.When core ring is connected completely in insertion groove, sphere on the outside of connection core ring is with the sphere laminating being connected on the inside of U-shaped cutting ferrule and concentric, then connection core ring is rotated into 90 degree, make the axis of connection core ring and the dead in line for being connected U-shaped cutting ferrule, connection core ring completes to install, and will not deviate from from the inner chamber of connection U-shaped cutting ferrule.
When needing with universal coupling assembly connecting cover plate and riser, as shown in Figure 3, Figure 4, we first can be fixed on connection U-shaped cutting ferrule as on the cover plate of horizontal sheet material portions, certainly, we can arrange a connection ring 312 of the circle with screw via on connection U-shaped cutting ferrule away from one end of support shaft, so as to available screw easily fixes connection U-shaped cutting ferrule.Then connection core ring is installed to as previously mentioned and is connected in U-shaped cutting ferrule, support shaft is connected on connection core ring again, now can be using as in the U-shaped buckle for directly snapping into support shaft to the upper side edge of the riser of sheet material portions, and U-shaped buckle is fixed with riser with screw, you can riser is formed with cover plate and be rotatably connected.Then the angle between riser and cover plate is accurately determined with the gauge of a fixed angle, and with angular adjustment component fixes the angle between riser and cover plate.Certainly two universal coupling assemblies should be at least positioned apart between riser and cover plate, and then can be connected using the universal coupling assembly of identical method between riser and base plate, here does not do excessive description.It is understood that gauge can be made according to the design angle between two plates, two sides of gauge are made when using while tight abutment two plates, you can make two plates form satisfactory angle.
