Embodiment

The technical solution of the utility model is described in further detail below in conjunction with Figure of description.

As shown in Figure 1-2, the handle of the technical program is the handle 4 for producing dynamo power；Described handle 4 passes through Regulator drive mechanism is with driving the driving wheel of rear wheel to be connected；Each described driving wheel be equipped with 1 set be used for realize high speed The regulator drive mechanism of shelves, low or first gear and the switching of reverse gear third gear, often cover regulator drive mechanism and be equipped with a handle 4, it is described Handle 4 be for realize top gear, low or first gear and reverse gear third gear switching and moving operation swing type handle.Swing type handle Hand can easily realize the multi gear switching of top gear, low or first gear and reverse gear, when driving, be realized by the swing of handle Hand driven bicycle is advanced, simple in construction, easy to operate.

In the present embodiment, hand driven bicycle includes car body 1, the Chinese herbaceous peony wheel 2 located at the front portion of car body 1, located at the rear portion of car body 1 Back wheels of vehicle 5, the seat 3 located at the top of car body 1, the handle 4 for producing dynamo power, the tune for realizing speed governing and transmission Fast transmission mechanism, steering mechanism, pedal brake 6 and pedal 7 for realizing steering, back wheels of vehicle 5 include 2 or so Symmetrically independent driving wheel, each driving wheel are equipped with 1 set of tune for being used to realize top gear, low or first gear and the switching of reverse gear third gear Fast transmission mechanism, often cover regulator drive mechanism and be equipped with a handle 4.

In order to realize that the switching of the third gear of handle 4 and hand driven bicycle travel unidirectionally, handle 4 passes through connecting rod 12 and speed governing Transmission mechanism is connected, and the lower end of connecting rod 12 is connected by unilateral bearing with the axletree of back wheels of vehicle 5, and back wheels of vehicle 5 passes through one-way shaft Hold and be connected with axletree, sun gear 8 that regulator drive mechanism includes being fixedly connected with car body 1, with sun gear 8 engage the planet being connected Wheel 9, the reversing pole 11 being connected with the lower end of connecting rod 12, the astern wheel 10 for being connected to reversing pole 11 lower end, planetary gear 9 connect In the middle and upper part of connecting rod 12, planetary gear 9 can be departed from and sun gear 8 forward or backward by being realized before and after handle 4 to swing Engagement, be top gear when planetary gear 9 engages with sun gear 8, planetary gear 9 is low or first gear when departing from and mediate with sun gear 8 forward, It is reverse gear when planetary gear 9 is disengaged from sun gear 8 backward, astern wheel 10 is connected by unilateral bearing with reversing pole 11. By the position of handle 4 and the convenient switching for realizing top gear, low or first gear and reverse gear of the conversion of angle, pass through one-way shaft Hold, swinging back and forth for handle 4 is converted into travelling unidirectionally for hand driven bicycle.

For the ease of realizing different operations, handle 4 includes removably being fixed in the connecting shaft on the top of connecting rod 12 401st, it is that Chinese herbaceous peony wheel 2 arrives the 0.7 ~ 1.2 of the distance of back wheels of vehicle 5 with the rocking bar 402 connected vertically of connecting shaft 401, the length of rocking bar 402 Times, seat 3 is located at the postmedian of car body 1.The length of rocking bar 402 is easy to vehicle drive people to realize difference when being sitting on seat 3 Operation.

For the ease of gripping and operating, 1.2 times away from more than or equal to the width of seat 3 between left and right of 2 rocking bars 402, rocking bar 402 towards the front upper place of seat 3.By the way that rocking bar 402 located at the both sides of seat 3 and towards front upper place, is easy to vehicle drive people's Grip and operate.

For the ease of the operation of shorter small people, rocking bar 402 is provided with pole 403 backward, the curved bend of pole 403 It is bent.When high speed is advanced, height can carry out swinging operation with respect to pipsqueak by gripping pole 403.

In order to realize preferable security, rocking bar 402 and pole 403 are round steel pipe, the upper end of rocking bar 402 and pole 403 lower end is equipped with spherical end 404.Pipe and spherical head security are good.

By the formula handle 4 that swings back and forth realize third gear switching and moving operation, when driving, by handle 4 come Backswing is dynamic to realize that hand driven bicycle is advanced.

When advancing at a high speed, planetary gear 9 engages with sun gear 8 all the time, and the respective handle 4 of hands grasping, which swings back and forth, drives car Move ahead；When low speed is advanced, both hands pull respective handle 4 to depart from forward and engaged with sun gear 8, and then hands grasping is respective Handle 4 swings back and forth, and realizes that low speed is advanced；During reversing, it is double grip handles 4 and backward depart from engaged with sun gear 8, then both hands Grip respective handle 4 to swing back and forth, realize car backing operation.

A kind of handle for hand driven bicycle shown in figure 1 above -2 is specific embodiment of the utility model, The utility model in essence feature and progress are embodied, can be right under enlightenment of the present utility model according to the use needs of reality It carries out shape, the equivalent modifications of structure etc., this programme protection domain row.
