The transmission mechanism 6 includes a first sprocket 61, a second sprocket 62, a third sprocket 63, and a first chain 64. The one-way wheel structure 5 is connected between the end of the operating portion 4 and the first sprocket 61. The second chain wheel 62 and the driving wheel are both rotationally connected with the frame 1, the third chain wheel 63 is linked with the driving wheel, and the first chain 64 is sleeved outside the second chain wheel 62 and the third chain wheel 63. The first sprocket 61 engages a lower horizontally extending run of the first chain 64, with the first sprocket 61 being positioned above the run of the first chain 64, as shown in FIG. 1.

In this embodiment, the ratchet structure includes a ratchet 52 and a pawl 51, and the pawl 51 is located outside the ratchet 52, as shown in fig. 2. The ratchet 52 is fixed to one end of the climbing-rod-shaped operating part 4, and the pawl 51 is fixedly connected to the first sprocket 61 coaxially. In fig. 2, the pawl 51 can rotate clockwise relative to the ratchet 52 and cannot rotate counterclockwise relative to the ratchet 52. Therefore, when the upper and/or lower limbs of the user drive the operation portion 4 in the form of a climbing pole to move linearly backward, the ratchet structure is in a locked state, the first chain wheel 61 drives the lower horizontal extension section of the first chain 64 to move backward, the rear wheel 2 of the driving wheel rotates clockwise, and the vehicle in the climbing posture rides forward.

The wheels comprise steering wheels, and the front wheels 3 are steering wheels. The real crawling mechanism further comprises a steering mechanism 8. The frame 1 is connected with the steering wheel through a steering mechanism 8.

The real crawling mechanism of the crawling posture riding vehicle further comprises a braking system connected to the wheels, and the braking system is connected with a braking operating rod 9. The brake operating lever 9 is provided on the grip 83. The structural principle of the braking system is the same as that of a traditional crawling posture riding vehicle. The brake operating lever 9 is linked with a brake system on the wheel through a pull rope.

In this embodiment, each hand corresponds to one grip 83, and each grip 83 controls the steering of one front wheel 3. Alternatively, only one long grip 83 may be provided, and both hands may grip the grip 83 at the same time, and the grip 83 may control the steering of one front wheel 3. In addition, only one front wheel can be arranged, and the two grips 83 can simultaneously drive the front wheels 3 to steer through a flexible shaft respectively.

Example 3

As shown in fig. 5, the difference from embodiment 1 is in the structure of the transmission mechanism 6. The transmission mechanism 6 comprises a toothed rack 65 and a toothed wheel 66 which are in engagement. The rack 65 is parallel to the rail 7. The rack 65 is in sliding engagement with the frame 1. The driving wheel is a rear wheel 2 and is rotationally connected with the frame 1, and the gear 66 and the rear wheel 2 are coaxially arranged and are connected through a one-way wheel structure 5. The one-way wheel structure 5 is the same as that of the embodiment 1, the gear 66 is coaxially and fixedly connected with the pawl 51, and the ratchet wheel 52 is coaxially and fixedly connected with the rear wheel 2. The steering mechanism 8 is the same as that of embodiment 1.

Example 4

As shown in fig. 6 and 7, the difference from embodiment 1 is that the vehicle frame 1 includes a trunk support portion. The transmission mechanism 6 includes two arm supports 67 and two leg supports 68.

Both the front wheel 3 and the rear wheel 2 are driving wheels. The operating part 4 of the rear wheel 2 is provided with a shoe cover or a bandage for fixing the sole of a foot.

The arm support 67 and the leg support 68 are fixed to the limbs through the binding bands, respectively. The middle parts of the arm support 67 and the leg support 68 are provided with a rotary joint 69, so that the elbow joint of the upper limb and the knee joint of the lower limb can be properly bent during crawling, and the crawling action is smoother. When the steering mechanism 8 is not present, the operating portion 4 is directly connected to the one-way wheel structure 5.

In this embodiment, the front wheels 3 are also steered wheels. The real crawling mechanism further comprises a steering mechanism 8. A steering mechanism 8 is connected between the operating part 4 on the arm support 67 and the corresponding one-way wheel structure 5. The steering mechanism 8 includes a connected grip 83, a turn bar 84, and a cross arm 85. One end of the cross arm 85 is connected to the driving wheel through the one-way wheel structure 5, the rotating rod 84 extends up and down, and the middle portion thereof is rotatably connected to the operating portion 4.

The operation section 4 is indirectly connected to the one-way wheel structure 5 via a crossbar 85.

The structure of the one-way wheel structure 5 is the same as that of embodiment 1. When the four limbs drive the arm frame 67 and the leg frame 68 to swing backwards, the driving wheels are subjected to the forward friction force of the ground, the one-way wheel structure 5 is in a locked state, the driving wheels are locked and cannot rotate relative to the arm frame 67 or the leg frame 68, and the driving wheels enable the vehicle in the crawling posture to move forwards under the reaction of the friction force of the ground. When the four limbs drive the arm frame 67 and the leg frame 68 to swing forward, the driving wheel rotates clockwise under the friction force of the ground to the backward direction, at this time, the one-way wheel structure 5 is unlocked, and the driving wheel can rotate relative to the arm frame 67 or the leg frame 68.

Example 5

As shown in fig. 8 and 9, the difference from embodiment 1 is that the operation portion 4 is provided in a linearly extending section of the endless crawler belt. The transmission mechanism 6 comprises a first belt wheel 602 and a second belt wheel 603 which are rotationally connected to the frame 1 and are respectively arranged in front and at back. The first pulley 602 and the second pulley 603 are each two and arranged left and right. The two crawling belts are respectively sleeved on the outer sides of the first belt wheel 602 and the second belt wheel 603 on the left side and the right side, and the upper layer of straight line extension section and the lower layer of straight line extension section of the crawling belt are both upwards and slightly obliquely arranged.

The transmission 6 also comprises a reversing transmission which links the second pulley 603 with said drive wheel. The one-way wheel structure 5 is arranged on the second belt wheel 603, the driving wheel or the reversing transmission mechanism. In this embodiment, the reversing gear mechanism includes a first reversing gear 604 and a second reversing gear 605 that are engaged with each other.

The pawl 51 of the ratchet structure is coaxially and fixedly connected with the second belt wheel 603, the ratchet 52 is coaxially and fixedly connected with the first reversing gear 604, and the second reversing gear 605 is coaxially and fixedly connected with the rear wheel 2. The rear wheel 2 is a driving wheel and is rotationally connected with the frame 1.

When a person steps on the linear extension section on the upper layer of the crawling belt and moves backwards, the ratchet structure is locked, the crawling belt rotates anticlockwise, the second belt wheel 603 drives the rear wheel 2 to rotate clockwise through the reversing transmission mechanism, and the crawling posture riding vehicle is driven to move forwards. When the foot drives the linearly extending section of the upper layer of the crawling belt to move forwards, the ratchet structure is unlocked, the crawling belt rotates clockwise, and the rear wheel 2 is not driven by the crawling belt and rolls along with the movement of the vehicle riding in the crawling posture. The steering mechanism 8 may be implemented in the following manner:

the first method is as follows: the steering mechanism 8 is the same as that in embodiment 1, and includes a turntable 81 and a first rotating shaft 82, and drives the turntable 81 to rotate through shoulders and a chest, so as to drive the front wheel 3 to rotate, or a person drives the turntable 81 to rotate through a head and a chin, so as to drive the front wheel 3 to rotate;

For driving body length and handlebar height, or only body length or handlebar height, since it is sufficient to allow a person to change from a seated ride to a crawling posture, e.g. with simultaneous downward and forward movement or backward and upward movement of the handlebars, and also to drive other accessory attachments

Similar structures can also be added to make other less important vehicle components, such as seats and the like, follow-up, i.e., change position simultaneously with changes in body length and handlebar height; for example, the side wheels beside the bicycle are folded or put down along with the change of the length of the bicycle body and the height of the handlebar, so as to increase the stability of the bicycle in the crawling posture, and the structures of the side wheels are shown in the following embodiments in detail.

Example 8

The pedal driving mechanism for riding is moved backwards, and the effect equivalent to the extension of the bicycle body is also achieved.

As shown in fig. 12 and 13, the bicycle employs a pedal driving mechanism that can move forward and backward. The pedal driving mechanism is not limited to any driving manner, such as shaft driving, chain driving.

According to the structure and the size of the conventional bicycle, the front lower part of the seat of the conventional bicycle is provided with a pedal driving mechanism, and only one pedal driving mechanism is provided. The difference is that: the pedal driving mechanism of the invention is a pedal driving mechanism which can move back and forth. When the bicycle is used on roads and the like, a person sits on the bicycle seat like a conventional bicycle, and when the person is to lie on the front of the bicycle, the person holds the handlebar with unchanged hands, stands up with the lower limbs, slowly moves the pedal driving mechanism backwards and moves the pedal driving mechanism to a position suitable for the body length of the person. Because the feet and the crotch move backwards along with the pedal driving mechanism, the upper body of the person also bends down.

For safety, when the pedal driving mechanism moves backwards, the side wheel 208 connected to the bicycle is put on the ground, and after the side wheel 208 is contacted with the ground, the side wheel 208 can roll like a wheel to play an auxiliary supporting role, so that the bicycle is changed into two wheels. When people lie prone to ride the bicycle, the bicycle is safer.

The length of the pedal driving mechanism is longer than that of the conventional bicycle in order to perform the twisting exercise of the spine.

The pedal handle of the pedal driving mechanism adopts a structure capable of adjusting the length, so that a person can adjust the length according to the length of the legs.

The rear part of the saddle is made into a wide structure, so that when a person lies on the bicycle, the saddle can be lifted upwards in a follow-up manner to contact the person, and the person can lie on the saddle sometimes.

The pedal shaft 205 is fixedly connected with the center of the driving disc 201, the pedal shaft 205 is connected with the pedal driving mechanism moving guide rail 206 through a bearing and the like, so that the whole driving disc, the pedal handle and the like can move back and forth along the pedal driving mechanism moving guide rail 206, and the driving disc 201 drives the transmission shaft 203 to move back and forth. The pedal 207 handle is fixed on the pedal handle shaft, and the shaft of the pedal 207 is fixedly connected with the pedal handle. The rear gear 204 drives a flywheel, which drives the rear wheel of the bicycle, either directly or via a gear or the like.

The pedal driving mechanism on the other side also adopts the structure, and then the driving forces on the two sides are converged together through the transmission of gears and the like.

Can also add the side wheel structure, supplementary the vehicle that lets when riding does not fall to the side. One end of the push rod 207 is hinged with the pedal handle shaft 205, and the other end of the push rod 207 is hinged with the side wheel frame 209. The side wheels 208 are mounted on a side wheel frame 209, and the side wheel frame 209 is hinged and fixed on the bicycle frame. When the pedal driving mechanism moves backwards along the pedal driving mechanism moving guide rail, the pedal handle shaft 205 pushes the push rod 207, the push rod 207 pushes the side wheel frame 209 to move backwards and downwards, and the side wheel 208 approaches the ground. Edge wheels 208 may also be coupled to controller 128.

It is obvious if original whole structure includes that foot drive mechanism moves guide rail 206, transmission shaft 203 etc. just is the level setting, but to the driving direction, forward downward sloping, then foot drive mechanism also can the rebound when backward moving, then more is fit for the gesture of crawling that the people was lying prone and rides.
