[ detailed description ] embodiments

The utility model relates to a scooter folds up structure, as shown in fig. 1 to 7, including bottom plate 1, establish at the rear wheel subassembly (can be the subassembly of single or two rear wheels) 2 of this bottom plate 1 tail end, the breeches pipe 3, rotate through upper and lower slewing bearing 41, 42 and embolia steering spindle 4 in the sleeve part 31 of this breeches pipe 3, with the handlebar stem 5 of being connected on this steering spindle 4, connect the front wheel subassembly (can be single or two front wheels) 6 at 4 lower extremes of steering spindle, adorn at the handle 7 of 6 upper ends of this handlebar stem, and fold up structure 8, here:

the lower surface of the bottom plate 1 is provided with a folding storage groove 11;

the fork tube 3 comprises a circular sleeve part 31 and a diagonal connection part 32; the inclined connecting part 32 comprises a fixed inclined bracket 321 and a movable inclined bracket 322: one end of the declivity fixing bracket 321 is fixedly connected with the sleeve part 31 (here, welded); two sides of one end of the movable inclined bracket 322 are clamped on two sides of the fixed inclined bracket 321 and are connected with the fixed inclined bracket 321 through a first folding shaft 33 in a swinging way; the other end of the movable inclined bracket 322 is connected in the bottom plate 1 in a swinging way through a second folding shaft 34;

the folding structure 8 comprises an unfolding locking seat 81, a button 82, a handle 83 and a handle elastic positioning piece 84; the unfolding locking seat 81 is fixed in the folding storage groove 11 at the front end of the bottom plate 1; an expansion locking hole 811 is formed in the front of the expansion locking seat 81; one end of the handle 83 is connected in the incline positioning bracket 321 through a handle shaft 831 in a swinging manner, and the pushing position 832 at the other end can push against the unfolding locking hole 811 of the unfolding locking seat 81 when the scooter is in an unfolding state; the button 82 is arranged in a button hole 3221 of the upper inclined surface of the movable inclined bracket 322, and the lower end of the button can be in contact connection with the handle 83; the handle elastic positioning piece 84 is arranged in the movable inclined bracket 322 and acts on the handle 83 to enable the handle 83 to lean against the bottom of the button 82; when the button 82 is pressed, the handle 83 swings and the abutting portion 832 slides away from the expansion locking hole 811 of the expansion locking seat 81, so that the folding can be performed.

In the unfolded state of the present invention, as shown in fig. 1, 2, 6 and 7, the pushing position 832 of the handle 83 is pushed against the unfolding locking opening 811 of the unfolding locking seat 81, so that the user can play and slide. When folding is to be performed, the user presses the button 82 to make the handle 83 swing after overcoming the acting force of the handle elastic positioning element 84 and the resistance of the unfolding locking opening 811, and at this time, the pushing position 832 of the handle 83 swings away from the unfolding locking opening 811 of the unfolding locking seat 81, so that the scooter can be folded, and at this time, on one hand, the movable inclined bracket 322 swings to the folding accommodating groove 11 of the bottom plate 1 around the second folding shaft 34; on the other hand, the handle bar 5 is folded around the first folding shaft 33 toward the movable tilting bracket 322, thereby completing the folding of the scooter, as shown in fig. 3.

As can be seen from the above, the inclined connecting portion 32 of the fork tube 3 comprises the fixed inclined bracket 321 and the movable inclined bracket 322 which are connected together through the first folding shaft 33 in a swinging manner, and the movable inclined bracket 322 is connected in the folding and accommodating groove 11 of the bottom plate 1 through the second folding shaft 34 in a swinging manner, so that the movable inclined bracket 322 can be folded into the folding and accommodating groove 11 of the bottom plate 1, and the fixed inclined bracket 321 can be folded towards the movable inclined bracket 322, and the whole structure and the appearance of the scooter are completely different from those of a conventional scooter due to the brand new two-section folding structure, thereby indirectly contributing to the improvement of the interest of children in playing and using; and the scooter when expanding the state, through folding up the swing handle top of structure 8 just can in the expansion locking mouth 811 that expandes the locking seat 81, and when folding, press button 82 and make its tight position 832 in top of handle 83 swing back leave the expansion locking mouth 811 that expandes the locking seat 81 and just can fold the operation, consequently the utility model discloses an operation is more simple and convenient.

The handle resilient retainer 84 may be of a different configuration and its primary function is to assist in preventing the handle from easily falling out of the deployment locking aperture 811 of the deployment locking seat 81 when in the deployed state. For example, in the embodiment shown in fig. 6, the handle elastic positioning member 84 is a torsion spring, which is installed in the movable tilting bracket 322 through a torsion spring shaft 841, and then both ends of which respectively act on the inner bottom surface of the movable tilting bracket 322 and the handle 83; for another example, in the embodiment shown in fig. 7, the handle elastic positioning member 84 is a spring piece, one end of which is mounted in the movable inclined bracket 322, and the other end of which abuts against the handle 83.

Preferably, an adjusting screw 9 is screwed into the vertical screw hole 3211 of the fixed diagonal bracket 321, and the upper end of the adjusting screw abuts against the inner bottom surface of the movable diagonal bracket 322, so that the angle between the fixed and movable diagonal brackets is finely adjusted by screwing the adjusting screw 9, so that the tightening position of the handle completely abuts against the unfolding locking port of the fixed seat when the scooter is in the unfolding state, and the deviation of the tightening position of the handle from the unfolding locking port does not occur, thereby ensuring the rationality of locking in place between the handle and the unfolding locking port of all scooters during batch production, and in this embodiment, two adjusting screws 9 are clamped on two sides of the handle.

In this embodiment, as shown in fig. 1 to 5, the handlebar 5 and the steering shaft 4 are locked together by the locking ring assembly 10, so that the handlebar and the handlebar can be detached together when the scooter is folded, thereby saving the space occupied during carrying and storage. Of course, the handle bar 5 and the steering shaft 4 can also be connected through a folding structure of butt joint of the shaft and the shaft, so that the occupied space during carrying and storage can be better saved.

Generally, the deployment locking opening 811 of the deployment locking seat 81 is in a C-shape or an inwardly concave arc shape; the jacking position 832 of the handle is in a convex semicircular shape or an arc shape, so that the handle is prevented from loosening in the unfolding state, and the jacking position can smoothly slide out of the unfolding locking opening when the button is pressed to fold the bicycle.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the present disclosure, but rather to limit the scope thereof by the appended claims.
