Specific implementation mode

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally The every other embodiment that field those of ordinary skill is obtained without making creative work, belongs to this practicality Novel protected range.

Referring to FIG. 1, Fig. 1 is a kind of structural representation of specific implementation mode of steering provided by the utility model Figure.

In a specific embodiment, steering provided by the utility model is used for vehicle, which is specially certainly Driving or electric booster bicycle, in the embodiment by taking shared bicycle as an example.The steering includes being installed on the head tube of vehicle frame 1, the circumferential handlebar 2 for being rotatably installed on the head tube 1, and the front fork 3 affixed with the handlebar 2, front fork 3 and front vehicle wheel Wheel shaft is fixed, and drives front vehicle wheel rotation by the steering moment that handlebar 2 transmits.Further, which further includes week It to position limiting structure, is set between the main part and the handlebar, and the handlebar 2 is turned to relative to the head tube 1 It is circumferentially fixed by the circumferential position limiting structure when predetermined limit position.Circumferential position limiting structure be set to the head tube 1 with it is described It between handlebar 2, and limits the handlebar 2 and circumferentially rotates stroke relative to the head tube 1, it refers to handlebar that this, which circumferentially rotates stroke, The slewing area between two limit positions is turned to relative to head tube.

The concrete structure of above-mentioned circumferential direction position limiting structure can be, including be installed on the first lateral buffering of the connection sheet 4 Block 5 and the second buffer stopper 6 for being installed on the head tube 1；The connection sheet 4 includes main part 41, is set to the main part 41 First mounting portion 42 of one end and the second mounting portion 43 for being set to 41 other end of the main part, first mounting portion 42 weeks To the head tube 1 is rotatably installed on, second mounting portion 43 is fixedly installed in the front fork 3；The handlebar 2 relative to When the head tube 1 turns to predetermined limit position, first buffer stopper 5 leans with second buffer stopper 6.

The one end in aforementioned body portion 41 refers under Fig. 1 status, and the upper end of main part 41, correspondingly, the other end is Refer to the lower end of the state lower body portion, connection sheet refers to laterally the left and right sides direction of main part 41 under Fig. 1 status.

In theory, circumferential position limiting structure is not limited to above structure form, for example, can be in the transverse direction of connection sheet The limiting slot for opening up predetermined length installs sliding block in head tube, and sliding block is embedded into limiting slot and can be slided in limiting slot, When handlebar rotates, sliding block slides along limiting slot and stops in stroke end, to realize limit.It is apparent that the limiting slot Stroke should be consistent with the range that handlebar circumferentially rotates.

Specifically, aforementioned body portion 41 can be arcuate structure, and inner surface and 1 outer wall of head tube of the arcuate structure are affixed It closes, to improve space availability ratio, preferable bonding structure can also avoid the formation of wedge angle, improve security performance.It is apparent that the master The major function in body portion 41 is carrying and connects each mounting structure, may be plane platelet structures, or carry rectangular bending Structure.

Above-mentioned first buffer stopper 5 can be one or two, and when it is one, the first buffer stopper 5 can be installed on institute State any lateral of arcuate structure；When it is two, two first buffer stoppers 5 are divided into two sides of the arcuate structure Bian Shang；When the handlebar 2 turns to predetermined limit position relative to the head tube 1, second buffer stopper 6 in the side First buffer stopper 5 leans, and the limit in both direction may be implemented in two the first buffer stoppers 5 of setting, more preferably to tie Structure.For example, the predetermined limit position can be ± 135 ° or so circumferential, or other angles appropriate, to ensure at this When angle value, it will not twist subject to toppling.

Specifically, the first mounting portion 42 is the laminated structure between 1 end face of the handlebar 2 and the head tube, described Via is offered in laminated structure, the head tube 1 is inserted into after passing through the via in the head tube 1, can using this kind of structure It enough realizes the installation of connecting plate and head tube 1 and handlebar 2, and the first mounting portion 42 can be avoided to limit handlebar 2 in working range Rotation.The via is preferably arranged with 1 female coaxial of head tube, it is possibility to have the little deviation in preset range.

First buffer stopper 5 may be used the forms such as clamping or bonding and be connect with main part 41, for example, can be on main part 41 Card slot is opened up, first buffer stopper 5 is connected and fixed in the card slot, is easily installed by the way of clamping, and when first It is easy to disassemble when buffer stopper 5 needs replacing, to reduce maintenance cost.

Further, the mounting structure of bicycle basket can also be integrated on connecting plate, i.e., on first mounting portion 42 Threaded connection hole is opened up, bicycle basket across the bolt of the threaded connection hole by being fixed in first mounting portion 42, to letter Change bicycle basket mounting structure, and improves the integration of steering.

The first buffering that steering provided by the utility model includes connection sheet 4, to be installed on the connection sheet 4 lateral Block 5 and the second buffer stopper 6 for being installed on the head tube 1, wherein connection sheet 4 is rotationally pacified so that its first mounting portion 42 is circumferential It is fixedly installed in the front fork 3 loaded on the head tube 1, and with its second mounting portion 43, in the handlebar 2 relative to the head tube 1 when turning to predetermined limit position, and first buffer stopper 5 leans with second buffer stopper 6.The steering is in handlebar 2 circumferentially rotate is provided with position limiting structure in stroke, when handlebar 2 turns to extreme position, serve as position limiting structure two are slow It rushes block to lean to realize circumferential limit, to limit the circumferential free degree between handlebar 2 and head tube 1, avoids 2 phase of handlebar Position rotation is crossed for head tube 1, improves and rides and park safety；Meanwhile above-mentioned position limiting structure has pooling feature, avoids Rigid collision between parts.

In addition to above-mentioned steering, the utility model also provides a kind of vehicle including above-mentioned steering, the vehicle Refer to the prior art for other Each parts, and this will not be repeated here.Specifically, the vehicle be specially bicycle, electric vehicle or Electric booster bicycle, wherein bicycle can be private savings bicycle or shared bicycle.

Although the embodiments of the present invention have been shown and described above, it is to be understood that above-described embodiment is Illustratively, it should not be understood as limiting the present invention, those skilled in the art are in the scope of the utility model Inside it can make changes, modifications, alterations, and variations to the above described embodiments.
