Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 8, the scooter comprises a handlebar frame 1, a front wheel 2 arranged at the bottom of the handlebar frame 1, a pedal 3 with the front part connected with the handlebar frame 1, and a rear wheel 4 arranged at the bottom and the rear part of the pedal 3.

The handlebar frame 1 comprises a first rod 11 and a second rod 12 which are in relative sliding and telescopic connection, wherein the first rod 11 can be inserted into a rod cavity of the second rod 12 in a relative sliding manner along the length direction of the first rod 11, so that the overall height of the handlebar frame 1 can be adjusted to be suitable for children with different heights.

Between the first lever 11 and the second lever 12, there is provided a locking assembly for locking the two in a plurality of height gears, the locking assembly including a lock pin (not shown in the drawings) provided on the first lever 11, and a plurality of lock grooves 12c provided at intervals along the length direction of the second lever 12, and when the lock pin is inserted in one of the lock grooves 12c, the locking assembly locks so that the first lever 11 and the second lever 12 are relatively locked.

A locking mechanism 10 is further disposed between the first rod 11 and the second rod 12 for secondary locking to prevent inconvenience and danger due to a locking failure of the locking assembly. The locking mechanism 10 includes a locking block 5 provided on the second rod 12 so as to be relatively movable in a radial direction of the second rod 12, a locking portion provided on a side portion of the locking block 5 facing the first rod 11, and a plurality of engaging portions provided on the first rod 11 at intervals in a longitudinal direction and capable of being engaged and locked with the locking portion, where the locking portion is a locking protrusion 51 protruding from the locking block 5 and extending toward the first rod 11, and the engaging portion is a locking groove 11a provided on the first rod 11.

The lock mechanism 10 has a locked state and an unlocked state, and when the lock mechanism 10 is in the locked state, the locking projection 51 is inserted in one of the locking grooves 11 a; when the lock mechanism 10 is in the unlocked state, the lock projection 51 is disengaged from the lock groove 11 a. The locking mechanism 10 further comprises a locking wrench 6 rotatably arranged on the second lever 12 for driving the locking block 5 to move for switching the locking mechanism 10 from the unlocked state to the locked state, the locking wrench 6 further being capable of fixing the locking block 5 in the locked state

Specifically, referring to fig. 5 to 8, the second rod 12 includes a rod body 12a and a fixing seat 12b fixedly disposed on the rod body 12a, and the locking block 5 and the locking wrench 6 are disposed on the fixing seat 12 b. Here, the fixing seat 12b is disposed on an end portion of the rod body 12a, and has a guide hole communicating with the inner cavity of the rod body 12a, and the first rod 11 is inserted into the guide hole along its length direction and inserted into the inner cavity of the rod body 12 a. The fixed seat 12b is provided with a rotating shaft 7, the axial lead of the rotating shaft 7 is parallel to the axial leads of the first rod 11 and the second rod 12, and the locking wrench 6 is connected to the fixed seat 12b in a rotating way around the axial lead of the rotating shaft 7. The locking block 5 is provided with a kidney-shaped guide groove 52, and the rotation shaft 52 is inserted into the guide groove 52 to provide a guide when the locking block 5 slides radially toward or away from the first lever 11.

Referring to fig. 2, 4 and 6, the locking wrench 6 has a cam portion 61, and a wrench portion 62 connected to the cam portion 61, the cam portion 61 is rotatably connected around the rotating shaft 7, the cam portion 61 has a distal end 61a farthest from the rotating center line thereof, when the locking mechanism 10 is in the locking state, as shown in fig. 2, the distal end 61a abuts against the locking block 5, thereby pushing the locking block 5 to move toward the radial direction of the first rod 11 so that the locking protrusion 51 is fittingly inserted into the locking groove 11a, and at this time, the wrench portion 62 is circumferentially buckled on the outer circumferential portion of the fixed seat 12 b. When the lock mechanism 10 is in the unlocked state, as shown in fig. 4, the distal end 61a is disengaged from the lock block 5, and at this time, by applying a certain downward pressure to the first lever 11, the lock groove 11a presses the lock projection 51 outward, so that the lock block 5 can be moved away from the first lever 11, thereby disengaging the lock projection 51 from the lock groove 11a to be unlocked. The handle portion 62 is operated to drive the cam portion 61 to rotate, so that the distal end 61a can be driven to rotate to be separated from the locking block 5 or abut against the locking block 5, thereby unlocking or locking the locking mechanism 10, and the operation is very convenient.

When the device is specifically arranged, the first rod 11 can be arranged above the second rod 12, in this embodiment, the first rod 11 is a handlebar rod, the second rod 12 is a front fork rod, and the front wheel 2 is arranged at the bottom of the front fork rod. The number of the locking grooves 12c on the second lever 12 corresponds to the number of the locking recesses 11 a. Thus, when the locking assembly locks the first rod 11 and the second rod 12 in a certain height position, the locking mechanism 10 can be correspondingly locked in the certain height position, so that double locking is realized, and the stability of the height of the handlebar 1 is ensured.

To sum up, the utility model discloses a scooter, wherein set up locking mechanical system 10 between first pole 11 and the second pole 12 through can stretch out and draw back relatively on handlebar frame 1 and adjust, make handlebar frame 1 can be locked steadily under fixed high position, when locking assembly locking became invalid, locking mechanical system 10 can continue to play the effect of locking, and when height-adjusting between first pole 11 and the second pole 12, locking spanner 6 is opened, first pole 11 still can not make first pole 11 slide into second pole 12 because the unblock at once because locking block 5 cooperates with first pole 11, danger such as tong has been caused, thereby the factor of safety of use of scooter has further been improved.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
