Abstract
The utility model relates to a foot-actuated quadricycle, comprising a hand steered handle (1), a forestay (2), a car body (5), as well as two front wheels (3), two rear wheels (4), and a pedal drive device. The utility model not only reserves the character of the scooters, but also is strong in overall stability for being provided with four wheels to support the car body, so the utility model has the advantages of coherent operation, strong recreation, adaptation for the little children to use.
Description
" technical field " the utility model belongs to a kind of bicycle, particularly relates to a kind of quadricycle with foot drive device.
In " background technology " prior art, the product similar to the utility model is Kickboard Scooter, be to use the feet step on the ground with the acquisition onward impulse by the glider, and free-wheel one segment distance, stopping naturally then, it is coherent, simple and dull that slide action is owed.Though electronic, Motor driven skateboard car and bicycle are also arranged, and price is more expensive, be unfavorable for popularizing, and its instrumentality is greater than recreational.And, certain requirement is arranged for user's balanced capacity because all Kickboard Scooters are two-wheeled or tricycle structure, and therefore, these products and be not suitable for young children and use at present.
" summary of the invention " the purpose of this utility model promptly is to provide a kind of later-model foot-operated quadricycle, not only keeps the recreational of Kickboard Scooter but also can be fit to the purpose that the younger ones in an age group children use to reach.
The utility model comprises hand steered handle (1), front strut (2) and car body (5), it is characterized in that, the utility model also comprises 2 front vehicle wheels (3), 2 rear wheels (4), and the foot drive device of being made up of stretcher (6), tooth bar (7), gear (8), gear (9) and retracing spring (10), the driving device be made up of gear (11), sprocket wheel (12), chain (13), sprocket wheel (14); Tooth bar (7) and gear (8) engagement; Gear (8) and the same axle mounting of gear (9) pass through ratchet drive between the two; Gear (9) and gear (11) engagement; Be crankshaft drive between gear (11) and the sprocket wheel (12), between sprocket wheel (14) and the rear wheel (4).
The utility model has not only kept the characteristics of Kickboard Scooter, and has 4 wheels to support car body, and resistance to overturning is strong, so has the good effect that operation is coherent, recreational by force, be fit to younger ones in an age group children use.
" description of drawings " accompanying drawing part further discloses specific embodiment of the utility model, wherein:
Fig. 1, foot-operated quadricycle profile scheme drawing;
Fig. 2, foot-operated quadricycle drives and the driving device scheme drawing;
" specific embodiment " discloses a kind of foot-operated quadricycle of back-wheel drive in the utility model embodiment shown in the drawings.As shown in Figure 1, comprise hand steered handle (1), front strut (2) and car body (5), also comprise 2 front vehicle wheels (3) and 2 rear wheels (4).Front strut (2) is that segmentation assembles, and adopts live axle to connect between front strut (2) and the car body (5), to reach the purpose that can fold.
The utility model also can adopt the mode of f-w-d, and its driving device structure and transmission principle and back-wheel drive are basic identical, so do not do repeat specification.
As shown in Figure 2, foot drive device of the present utility model is made up of stretcher (6), tooth bar (7), gear (8), gear (9) and retracing spring (10).Driving device is made up of gear (11), sprocket wheel (12), chain (13), sprocket wheel (14).Wherein, pass through ratchet drive, gear (9) and gear (11) engagement, gear (11) and sprocket wheel (12) crankshaft drive, sprocket wheel (14) and rear wheel (4) crankshaft drive between tooth bar (7) and gear (8) engagement, gear (8) and gear (9), it cooperates in twos, forms one group of transmission respectively.
Of the present utility model advancing is achieved in that the stretcher that tramps with one's feet down (6), pass through tooth bar (7), gear (8), gear (9), gear (11), sprocket wheel (12), chain (13) and sprocket wheel (14) successively, motion is reached rear wheel (4), thereby drive wheels moves ahead.Owing to realize unidirectional transmission by ratchet between gear (8) and the gear (9), so after unclamping stretcher, under retracing spring (10) effect, stretcher can reset.And so forth, can drive to move ahead continuously.Therefore, the utility model has not only kept the characteristics of Kickboard Scooter, and operation links up, resistance to overturning is strong, is particularly suitable for the younger ones in an age group children and uses.
