[0052] The present application provides an auxiliary steering device. The present application also provides a cycling vehicle including the auxiliary steering device.

[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] like Figures 1 to 10As shown, an embodiment of the present application provides an auxiliary steering device, which is installed on a bicycle to assist the bicycle in steering. The bicycle is usually a bicycle for infants and young children, and the auxiliary steering device is used to assist the bicycle in steering. The auxiliary steering device mainly includes an auxiliary component 1, a force component 2 and a connecting component 3. Specifically, the auxiliary component 1 is connected to the steering component 4 of the bicycle, and can drive the steering component 4 to rotate to assist in steering the bicycle; the force component 2 is connected to the frame component 5 of the bicycle, and is used to bear the auxiliary steering force; one end of the connecting component 3 is connected to the auxiliary component 1, and the other end is connected to the force component 2, and the auxiliary steering force borne by the force component 2 can be transferred to the auxiliary component 1 through the connecting component 3. When the bicycle needs to turn, the supervisor applies a rotational force to the force component 2 with both hands, and the force component 2 will rotate relative to the frame component 5, and the force component 2 will transfer the rotational force to the connecting component 3, and the connecting component 3 will transfer the rotational force to the auxiliary component 1, and the auxiliary component 1 will transfer the rotational force to the steering component 4 of the bicycle to achieve the effect of assisting the steering component 4 to turn.

[0055] Further, the connection component 3 is connected to the auxiliary component 1 through a spherical pair, and / or the connection component 3 is connected to the force-bearing component 2 through a spherical pair. It should be noted that when the connection component 3 is connected to the auxiliary component 1 through a spherical pair, the ball head can be set on either the connection component 3 or the auxiliary component 1; when the connection component 3 is connected to the force-bearing component 2 through a spherical pair, the ball head can be set on either the connection component 3 or the force-bearing component 2.

[0056] In this embodiment, an optional implementation is provided, in which the connecting component 3 is connected to the auxiliary component 1 through a spherical pair, and the connecting component 3 is hinged to the force-bearing component 2.

[0057] Another optional implementation is also provided in this embodiment, in which the connecting component 3 is connected to the force-bearing component 2 through a spherical pair, and the connecting component 3 is hinged to the auxiliary component 1.

[0058] In this embodiment, another optional implementation is also provided, in which the connecting component 3 is connected to the auxiliary component 1 through a spherical pair, and the connecting component 3 is connected to the force-bearing component 2 through a spherical pair.

[0059] The auxiliary steering device of the above structure is achieved by connecting the connecting component 3 to the auxiliary component 1 through a spherical pair, and / or connecting the connecting component 3 to the force-bearing component 2 through a spherical pair. Since the spherical pair is provided, the auxiliary steering device is a spatial mechanism, and the auxiliary steering device has a greater degree of freedom, thereby improving the convenience of the layout of the auxiliary steering device in the bicycle and improving applicability.

[0060] In some embodiments, the force-bearing component 2 includes a force-bearing handle 21, a first connecting piece 22 and a first ball head 23. The force-bearing handle 21 is arranged on the frame component 5 through a connecting rod 211 that can rotate around its own axis; the first connecting piece 22 is radially protruding and arranged on the connecting rod 211, and rotates with the connecting rod 211; the first ball head 23 is arranged on the protruding end of the first connecting piece 22, and is connected with the connecting component 3 to form a spherical pair. Specifically, when the riding bicycle needs to turn, the supervisor applies a rotational force to the force handle 21 with both hands, and the force handle 21 rotates around its own axis relative to the frame assembly 5. When the force handle 21 rotates, it also drives the first connecting piece 22 which is radially protruding from the connecting rod 211 to rotate. Further rotation of the first connecting piece 22 will drive the first ball head 23 which is arranged on the protruding end of the first connecting piece 22 to rotate. The first ball head 23 and the connecting assembly 3 form a spherical pair. The first ball head 23 will transmit the rotational force to the connecting assembly 3, and the connecting assembly 3 will transmit the rotational force to the auxiliary assembly 1. Finally, the auxiliary assembly 1 will transmit the rotational force to the steering assembly 4, and finally the steering of the riding bicycle is realized.

[0061] Here, the force-bearing handlebar 21 is connected to the connecting assembly 3 via a spherical pair, which can improve the degree of freedom of the auxiliary steering device, thereby improving the applicability of the auxiliary steering device during steering, and can also improve the rationality of the arrangement of various components of the bicycle.

[0062] In some embodiments, the auxiliary component 1 includes a second connecting plate 11 and a second ball head 12; the second connecting plate 11 is radially protruding and arranged on the steering component 4, and drives the steering component 4 to rotate; the second ball head 12 is arranged on the protruding end of the second connecting plate 11, and is connected to the connecting component 3 to form a spherical pair. On the basis that the connecting component 3 and the force-bearing component 2 are connected by a spherical pair, the auxiliary component 1 and the connecting component 3 are also connected by a spherical pair. Specifically, when the riding vehicle needs to turn, the supervisor applies a rotational force to the force-bearing handle 21 with both hands, and the force-bearing handle 21 rotates around its own axis relative to the frame component 5. When the force-bearing handle 21 rotates, it also drives the first connecting piece 22 radially protruding from the connecting rod 211 to rotate. Further rotation of the first connecting piece 22 will drive the first ball head 23 arranged on the protruding end of the first connecting piece 22 to rotate. The first ball head 23 transmits the rotational force to the connecting component 3, and the connecting component 3 applies a rotational force to the second ball head 12. The second ball head 12 drives the second connecting piece 11 to rotate. The second connecting piece 11 applies a steering force to the steering component 4, thereby realizing that the second connecting piece 11 drives the steering component 4 to rotate, thereby realizing the steering of the riding vehicle.

[0063] Here, the connecting component 3 is connected to the auxiliary component 1 through a spherical pair, and the connecting component 3 is connected to the force-bearing component 2 through a spherical pair, which can further enhance the degree of freedom of the auxiliary steering device in assisting the steering of the bicycle and enhance the steering effect of the bicycle.

[0064] In some embodiments, the center lines of the first connecting piece 22 and the second connecting piece 11 are parallel. Specifically, the center lines of the first connecting piece 22 and the second connecting piece 11 are ensured to be parallel, so that when the force-bearing component 2 is adjusted to rotate to drive the auxiliary component 1 to rotate to drive the steering component 4 to rotate, the stability of the rotation of the first connecting piece 22 and the second connecting piece 11 is ensured, so that the rotation is labor-saving and the steering of the rotating component can be adjusted quickly.

[0065] Furthermore, the protruding length of the first connecting piece 22 is the same as the protruding length of the second connecting piece 11. With this arrangement, when turning, the steering angle of the first connecting piece 22 can be the same as the steering angle of the second connecting piece 11, and the steering angle of the force handle 21 can be the same as the steering angle of the steering assembly 4, thereby facilitating the adjustment of the steering angle of the steering assembly 4.

[0066] Furthermore, in order to improve the convenience of auxiliary steering, the first connecting piece 22 and the second connecting piece 11 are arranged on the same side of the riding vehicle.

[0067] In addition, the first connecting piece 22 and the second connecting piece 11 can also be arranged in other ways, for example, the extension lines of the center lines of the first connecting piece 22 and the second connecting piece 11 intersect, and such an arrangement can also achieve the function of assisting the steering of the riding bicycle.

[0068] In some embodiments, the connecting assembly 3 includes a transmission rod 31 and a connecting structure 32. There is a height difference between the two ends of the transmission rod 31, so that the shape of the transmission rod 31 can be flexibly set according to the setting positions of other components of the bicycle, thereby improving the diversity of the setting of the bicycle; there are at least two connecting structures 32, and they are respectively set at the two ends of the transmission rod 31; wherein, the connecting structure 32 located at one end of the transmission rod 31 is detachably connected to the first ball head 23, and the connecting structure 32 located at the other end of the transmission rod 31 is detachably connected to the second ball head 12. Such a setting can facilitate the installation of the auxiliary steering device of the bicycle. It should be noted that there is a height difference between the two ends of the transmission rod 31, and the value of the height difference is not limited. The height difference between the two ends of the transmission rod 31 facilitates the setting of other structures of the bicycle and reduces the difficulty of designing and installing the bicycle.

[0069] In addition, there may be no height difference between the two ends of the transmission rod 31, that is, the heights of the two ends of the transmission rod 31 are the same, so that the auxiliary steering device can also achieve the function of assisting the steering of the bicycle.

[0070] In some embodiments, the connection structure 32 includes a body 321, a stopper 322, and an elastic member 323. One end of the body 321 is connected to the transmission rod 31, and the other end is provided with a groove 3211 for accommodating the first ball head 23 or the second ball head 12, so that the first ball head 23 or the second ball head 12 can be extended into the groove 3211 along the radial direction of the body 321 to form a spherical pair with the groove 3211; the stopper 322 is movably sleeved on the end of the body 321 where the groove 3211 is provided along the axial direction of the body 321, and has a stopper 3221; the elastic member 323 is sleeved on the body 321, and one end is connected to the body 321, and the other end is connected to the stopper 322; wherein, the stopper 322 is driven by the elastic member 323 to move the stopper 3221 to the notch of the groove 3211 to block the first ball head 23 or the second ball head 12.

[0071] Specifically, when the force-bearing component 2 and the connecting component 3 need to be assembled, Fig. 9 The limiting portion 322 is pushed in the direction indicated by the arrow Y, and the limiting portion 322 moves in the direction indicated by the arrow Y. The blocking piece 3221 of the limiting portion 322 no longer blocks the notch of the groove 3211. The first ball head 23 is placed in the groove 3211, and then the limiting portion 322 is released. The limiting portion 322 moves along the direction indicated by the arrow Y under the action of the rebound force of the elastic member 323. Fig. 9 The first ball head 23 is moved in the direction indicated by the arrow X, and the blocking piece 3221 blocks the first ball head 23 again. At this time, the first ball head 23 and the inner wall of the groove 3211 form a spherical pair, so that the first ball head 23 and the connecting structure 32 are assembled, thereby realizing the assembly of the force-bearing component 2 and the connecting component 3. When the force-bearing component 2 and the connecting component 3 need to be disassembled, Fig. 9 The limiting portion 322 is pushed in the direction indicated by the middle arrow Y, and the limiting portion 322 moves along Fig. 9 The stopper 3221 of the limiting portion 322 no longer blocks the notch of the groove 3211, the first ball head 23 is removed from the groove 3211, and then the limiting portion 322 is released. The limiting portion 322 moves along the groove 3211 under the action of the rebound force of the elastic member 323. Fig. 9 The limiting part 322 moves in the direction indicated by the arrow X, and moves back to the original position, thereby realizing the disassembly of the force-bearing component 2 and the connecting component 3. Accordingly, the installation and disassembly methods of the auxiliary component 1 and the connecting component 3 are similar to the installation and disassembly methods of the force-bearing component 2 and the connecting component 3, and will not be repeated here.

[0072] With such a configuration, the operator can quickly install and disassemble the first ball head 23 or the second ball head 12 and the connecting structure 32 by simply adjusting the elastic member 323, thereby improving the installation and disassembly efficiency of the connecting component 3 and the force-bearing component 2, and improving the installation and disassembly efficiency of the connecting component 3 and the auxiliary component 1, thereby improving the installation and disassembly efficiency of the bicycle.

[0073] A bicycle comprising the auxiliary steering device. Since the bicycle comprises the auxiliary steering device, the beneficial effects of the bicycle brought by the auxiliary steering device can be seen in the above content, which will not be repeated here.

[0074] In the present embodiment, a cycling bike generally refers to a cycling bike used by infants and young children, and a cycling bike particularly refers to a sports rehabilitation device. It should be noted that SMA is a hereditary disease that mainly affects the neuromuscular system of infants and young children, leading to symptoms such as muscle weakness and atrophy. The lower limb muscles of SMA patients are often affected, leading to problems such as abnormal gait and difficulty walking. In order to help SMA patients, a cycling bike is provided, which is a movable rehabilitation training device that can achieve sports training for the lower limbs of children through pedaling cycling movements. However, since SMA patients often have weak upper limb strength, they may not be able to control the direction of the device well. Therefore, the present invention provides the above-mentioned auxiliary steering device, which is convenient for the guardian to assist the child in controlling the forward direction of the device when necessary to ensure safety of use. By using the cycling bike of the present invention, SMA children can more effectively perform lower limb motor rehabilitation and promote the recovery of muscle strength and function. The device is simple in structure, easy to operate, safe and reliable, and is suitable for rehabilitation training of SMA children.

[0075] In some embodiments, the frame assembly 5 includes a frame body 51 and a connecting tube 52 that is rotatably sleeved with the connecting rod 211, and the connecting rod 211 extends into the connecting tube 52 to realize the connection between the force-bearing assembly 2 and the riding vehicle. The connecting rod 211 is provided with a first stopper 212; the connecting tube 52 is provided with a strip stopper groove 521 that allows the first stopper 212 to pass through and extends along the circumference of the connecting tube 52; the connecting rod 211 drives the first stopper 212 to rotate in the strip stopper groove 521 to achieve the limit of the first stopper 212 and the connecting rod 211. When the riding vehicle needs to turn, the supervisor applies a rotational force to the force-bearing handle 21 with both hands, and the connecting rod 211 of the force-bearing handle 21 rotates along its own axial direction, driving the first stopper 212 set on the connecting rod 211 to rotate, and the first stopper 212 rotates in the strip stopper groove 521 to achieve the limit of the first stopper 212 and the connecting rod 211.

[0076] Exemplarily, the first stopper 212 is a stopper protrusion radially protruding from the connecting rod 211, the stopper protrusion is detachably connected to the connecting rod 211, a plurality of holes are arranged on the connecting rod 211, when the connecting rod 211 and the connecting tube 52 need to be connected together, the connecting rod 211 is inserted into the connecting tube 52, and the stopper protrusion passes through the strip stopper groove 521 and is inserted into the hole of the connecting rod 211, thereby realizing the detachable connection between the first stopper 212 and the connecting rod 211. It should be noted that the connection between the stopper protrusion and the hole can be a snap connection, a magnetic connection, etc.

[0077] Further, in some embodiments, the first limiting member 212 is a limiting marble. Specifically, the limiting marble can move relative to the connecting rod 211 along the radial direction of the connecting rod 211, so that when the connecting rod 211 needs to be installed in the connecting tube 52, an extrusion force is applied to the limiting marble in the direction toward the connecting rod 211, and the limiting marble is pressed into the connecting rod 211, and the connecting rod 211 is inserted into the connecting tube 52 until the limiting marble moves to the position of the strip limiting groove 521, and the limiting marble pops out, and the limiting marble is just located in the strip limiting groove 521. Such a setting can quickly realize the limiting abutment between the first limiting member 212 and the strip limiting groove 521, and can quickly realize the installation of the connecting rod 211 and the connecting tube 52, improve the installation efficiency, and can improve the adaptation accuracy of the limiting marble and the strip limiting groove 521.

[0078] In some embodiments, a second stopper 6 connected to the frame 51 of the frame assembly 5 is further included, and the transmission rod 31 is arranged in the second stopper 6 to limit the degree of freedom of the transmission rod 31. Specifically, the second stopper 6 is a stopper ring, and the transmission rod 31 is a rod-shaped structure. The transmission rod 31 passes through the stopper ring and is located in the stopper ring. When the auxiliary steering device is subjected to the auxiliary steering force, the transmission rod 31 may touch the rider's calf or ankle during movement due to excessive freedom. Therefore, by setting the second stopper 6 connected to the frame, the transmission rod 31 is arranged in the second stopper 6, so as to limit the degree of freedom of the transmission rod 31, thereby preventing the transmission rod 31 from touching the rider's calf or ankle, and improving the safety of the auxiliary steering device when in use.
