Description

Front wheel of scooter transfer

Technical field

This utility model is related to a kind of scooter steering technique, particularly a kind of slide plate being rotated by steering handle Car steering unit for front wheels.

Background technology

The steering mechanism of existing scooter does not have auto-reset function, needs handss after existing scooter manual steering Move and resetted, operation is laborious, inadequate hommization：

Scooter due to have flexibly light, recreational strong, body-building effect is good the features such as, be popular in users, special It is not affected by liking of youngsters and children.The species of scooter is more, and most popular is that two front-wheels are arranged on bogie Scooter, but this car can not automatically reset in steering operation, need to use hand-reset, and operation is laborious, inadequate hommization.For this reason, Chinese utility model patent Authorization Notice No. discloses a kind of steering mechanism of scooter for CN204998708U, when this structure promotes When block turns left, right jacking block top pressure block makes bogie along steering spindle rotate in an anti-clockwise direction, realizes, pushing block simultaneously One end of female 8 top pressure torsion spring, makes torsion spring have an elastic potential energy to the right, when user stops to applying of turning left When strength, torsion spring resets and promotion block reset, drives pushing block and steering handle to reset.But deposit in use In following deficiency：Due to promoting the block on bogie to realize turning to when turning to by the jacking block of pushing block, turn to each other Idle stroke is big not to be turned to therewith it is simply that starting bogie during rotation, and steering stability is poor, and drive mechanism is complicated.For this reason, it is many Manufacturer and knowledgeable people are researched and developed for the problems referred to above, but not yet have comparatively ideal product so far in market On emerge.

Content of the invention

For the disadvantages mentioned above overcoming existing steering mechanism of scooter to exist, the purpose of this utility model is to provide a kind of structure Advantages of simple, flexible operation are light, stable direction is reliable, turn to automatically reset front wheel of scooter transfer.

This utility model solves the technical scheme that its technical problem is adopted, it include both sides install front-wheel bogie, Steering spindle, steering base, steering spindle is installed in rotation on the centre bore of bogie by bearing, and steering base is fixedly connected on and turns To on axle, the vertical line of described bogie front axle line is provided with limiting steering block, and the both sides of limiting steering block are correspondingly provided with torsion Spring loose slot, the steering spindle between steering base and bogie is cased with the reduction torsion spring of V-shaped structure, reduction torsion spring both sides hook arm It is correspondingly arranged in the torsion spring loose slot of limiting steering block both sides, the lower section of steering base is provided with the torsion spring seat covering reduction torsion spring, Torsion spring seat is provided with the torsion spring seat notch matching with reduction torsion spring both sides torque arm.

Further scheme of the present utility model, described bogie is provided with safety screen.

After said structure, this utility model has the following advantages and effect, and one is that when turning to, steering base passes through torsion spring seat Torsion spring seat notch promote the reduction torsion spring of side, the hook arm of reduction torsion spring mobile and elastic energy storage in torsion spring loose slot, with When opposite side reduction torsion spring hook arm promote bogie to turn to, structure is simple, and stable direction is reliable；When unclamping steering, multiple Position torsion spring elastic force effect lower drive bogie automatically resets and keeps straight trip direction；Two is that reduction torsion spring both can play promotion steering Frame steering-effecting, can play reset response again, may also operate as steering angle positioning action simultaneously.Setting peace on three bogies Full baffle plate, not only can improve the security performance of use, and can greatly improve the mechanical strength of bogie, and product design is beautiful See generous.

Fig. 2 unloads fit structure schematic diagram during steering base for this utility model.

Fig. 3 is the structural representation of this utility model steering base.

Fig. 4 is the structural representation of this utility model bogie.

Wherein 1 bogie, 2 safety screens, 3 reduction torsion springs, 4 steering bases, 5 steering spindles, 6 torsion spring loose slots, 7 limiting steerings Block, 8 torsion spring seat notches, 9 torsion spring seats, 10 centre bores.

Specific embodiment

Shown in Fig. 1 to Fig. 4, it is a kind of specific embodiments of this utility model front wheel of scooter transfer, it includes The bogie 1 of both sides installation front-wheel, steering spindle 5, steering base 4, steering spindle 5 is installed in rotation on the centre bore 10 of bogie 1 On, steering base 4 is fixedly connected in steering spindle 5, and steering handle is fixedly connected on steering base 4, and described bogie 1 front axle is even The vertical line of line is provided with limiting steering block 7, and the both sides of limiting steering block 7 are correspondingly provided with torsion spring loose slot 6, steering base 4 and steering The reduction torsion spring 3 of V-shaped structure is cased with the steering spindle 5 between frame 1, reduction torsion spring 3 both sides hook arm is correspondingly arranged at steering limit In the torsion spring loose slot 6 of position block 7 both sides, the lower section of steering base 4 is provided with the torsion spring seat 9 covering reduction torsion spring 3, and torsion spring seat 9 sets There is the torsion spring seat notch 8 matching with reduction torsion spring 3 both sides torque arm.Described bogie 1 is provided with safety screen 2.

About scooter steering handle of the present utility model during gravimetric tilt, steering handle drives torsion spring by steering base 4 Seat 9, the torsion spring seat notch 8 of torsion spring seat 9 promotes reduction torsion spring 3 torque arm of this side, and the hook arm of reduction torsion spring 3 is in torsion spring loose slot 6 Interior movement elastic energy storage, simultaneously opposite side reduction torsion spring 3 hook arm promote bogie 1 turn to, thus realize scooter turn to. When the hook arm of reduction torsion spring 3 is contacted with limiting steering block 7, limit steering handle and rotate, can turning with effective control scooter To angle.When unclamping steering handle, drive steering handle, steering base 4 and bogie 1 under the effect of reduction torsion spring 3 elastic force certainly Dynamic reset, thus ensure that scooter keeps direction of keeping straight on automatically.

The above, simply specific embodiment of the utility model, not this utility model is made any pro forma Limit, on the basis of without departing from the technical solution of the utility model, done simple modification, equivalent variations or modification, all fall Enter protection domain of the present utility model.
