[0077] Bicycles, also known as bicycles or bikes, are usually two-wheeled small land vehicles. As a means of transportation for humans, bicycles have a long history of use and development and play an important role in people's daily work and life.

[0078] Bicycles have good passing ability. They can travel quickly on flat asphalt and concrete roads, and can also travel slowly on muddy roads, gravel roads and other harsh roads.

[0079] However, in the related art, it is often difficult for bicycles to pass through congested roads or obstacles such as rivers, swamps, mud pits, and mountains.

[0080] In order to solve the above technical problems, the embodiment of the present application provides a ground-to-air dual-purpose bicycle. The ground-to-air dual-purpose bicycle provided by the embodiment of the present application is described in detail below with reference to the drawings of the specification.

[0081] Please refer to Figures 1 to 3 The present application proposes a ground-to-air dual-purpose bicycle 100, which includes a frame 3, a wheel 1, a plurality of rotor assemblies 2, and a controller (not shown in the figure). The plurality of rotor assemblies 2 are arranged on both sides of the wheel 1 and are movably connected to the frame 3; the rotor assemblies 2 have a folded position and an extended position, and can be switched between the folded position and the extended position. The controller is installed on the frame 3 and is electrically connected to the rotor assemblies 2. In addition, see Figure 3 The ground-air dual-purpose bicycle 100 may also include a power battery 9, which is used to supply power to electrical devices such as a controller and a rotor assembly 2.

[0082] The frame 3 is a core structural component of the ground-air dual-purpose bicycle 100 and is the installation base of structural components such as the wheel 1. The structure of the frame 3 will be described in detail below.

[0083] The number of rotor assemblies 2 can be two, three, four, six, eight, etc. The specific number of rotor assemblies 2 can be flexibly determined according to factors such as the number of wheels 1 of the ground-air dual-purpose bicycle 100 (such as a unicycle, a multi-wheeled bicycle), and the embodiment of the present application does not specifically limit this.

[0084] There are many ways to implement the switching of the rotor assembly 2 between the folded position and the deployed position. In one possible implementation, the rotor assembly 2 can be set in the folded position or the deployed position by manual operation and fixed by fasteners. In another possible implementation, the rotor assembly 2 can be driven to switch between the folded position and the deployed position by a combination of a motor and a transmission mechanism, wherein the transmission mechanism can be at least one of a multi-link mechanism, a gear transmission mechanism, a belt transmission mechanism, an electric push rod and the like. The motor is electrically connected to the power battery 9. After the motor is started, the transmission mechanism can drive the rotor assembly 2 to switch between the folded position and the deployed position.

[0085] It should be noted that the motion state of the ground-air dual-purpose bicycle 100 of the present application is different according to the different positions of the rotor assembly 2. When the rotor assembly 2 is in the folded position, the rotor assembly 2 is folded and close to both sides of the wheel 1, the rotor assembly 2 is not working, and the ground-air dual-purpose bicycle 100 can travel on the ground; when the rotor assembly 2 is in the unfolded position, the rotor assembly 2 is in an extended state and spreads toward both sides of the wheel 1 away, and the rotor assembly 2 generates lift through rotation, which can make the ground-air dual-purpose bicycle 100 fly in the air.

[0086] The controller can change the size and direction of the lift by controlling the rotation speed of the rotor assembly 2 and the windward angle of the blades, thereby controlling the flight of the ground-air dual-purpose bicycle 100 in the air. The controller can be a control unit of the flight control system in the ground-air dual-purpose bicycle 100, or a dedicated control module.

[0087] The solution provided by the present application is that when riding on the ground is blocked, the rotor assemblies 2 on both sides of the wheel 1 in the ground-to-air bicycle 100 can be switched from the folded position to the unfolded position, and the ground-to-air bicycle 100 can fly over the congested road or obstacles under the control of the controller. It can be seen that the passing ability of the bicycle is further improved through the present application, so the problem that the bicycle in the related art is difficult to pass when facing congested roads or obstacles can be solved.

[0088] See also Figure 3 In some embodiments, the number of wheels 1 is at least two. The frame 3 includes a main frame body 31, a front fork 32 and a rear fork 33; the front fork 32 connects the main frame body 31 and one wheel 1, and the rear fork 33 connects the main frame body 31 and another wheel 1. The front fork 32 and the rear fork 33 are both provided with a support member 320, and the rotor assembly 2 is rotatably connected to the support member 320. The rotor assembly 2 rotates around a first axis X, and the first axis X intersects with the axis of rotation of the wheel 1.

[0089] The number of wheels 1 can be two, three, four, etc. Figure 3 As shown, the wheel 1 may include a front wheel 11 and a rear wheel 12. The embodiment of the present application does not specifically limit the number of wheels 1, and designers may flexibly set the number according to actual needs.

[0090] It is understandable that the support member 320 provided on the front fork 32 can be fixed on the front fork 32 by welding, screwing, etc., or can be integrally formed with the front fork 32 by casting, etc. Similarly, the support member 320 provided on the rear fork 33 can be fixed on the rear fork 33 by welding, screwing, etc., or can be integrally formed with the rear fork 33 by casting, etc.

[0091] The main frame 31 is the main body of the frame 3, and a front fork 32 is installed on the front side of the main frame 31, and the front fork 32 is used to install the front wheel 11. A rear fork 33 is installed on the rear side of the main frame 31, and the rear fork 33 is used to install the rear wheel 12.

[0092] The plurality of rotor assemblies 2 are connected to the vehicle frame 3 via support members 320 disposed on the front fork 32 and the rear fork 33 , and are capable of rotating about a first axis X intersecting with the axis of rotation of the wheel 1 .

[0093] It should be noted that, for multiple wheels 1, the first axis X of rotation of the rotor assembly 2 mounted on the front fork 32 and the first axis X of rotation of the rotor assembly 2 mounted on the rear fork 33 may be parallel or intersecting, such as Figure 3 shown.

[0094] By providing support members 320 on the front fork 32 and the rear fork 33, the embodiment of the present application can conveniently connect the rotor assembly 2 to the frame 3 through the support members 320, so that the rotor assembly 2 can be switched between the folded position and the deployed position by rotating the rotor assembly 2, so that the dual-purpose ground-to-air bicycle 100 can both travel on the ground and fly in the air.

[0095] See also Figure 3 and Figure 4 In some embodiments, the rotor assembly 2 includes a bracket 21, a connecting shaft 22, and a rotor 23. The bracket 21 is rotatably connected to the support member 320 around a first axis X. The connecting shaft 22 is rotatably connected to the bracket 21 around a second axis Y in a manner in which the rotation angle can be adjusted, and the second axis Y intersects the first axis X. The rotor 23 is disposed at an end of the connecting shaft 22 away from the wheel 1.

[0096] The connecting shaft 22 is rotatably connected to the support member 320 through the bracket 21, and the end of the connecting shaft 22 away from the wheel 1 is connected to the rotor 23. When the rotor assembly 2 is in the deployed position, the connecting shaft 22 can keep the rotor 23 away from the wheel 1 to avoid interference between the rotor 23 and the wheel 1.

[0097] Since the connecting shaft 22 is rotatably connected to the bracket 21 around the second axis Y in an adjustable rotation angle, the connecting shaft 22 can be rotated relative to the bracket 21 before the rotor assembly 2 is switched to the folded position, for example, the rotor 23 of the rotor assembly 2 connected to the rear fork 33 faces the ground, and the rotor 23 of the rotor assembly 2 connected to the front fork 32 faces the front side of the ground-to-air bicycle 100. In this way, when the rotor assembly 2 is switched to the folded position, the space occupied by the rotor 23 can be reduced, making the ground-to-air bicycle 100 in the folded position more compact.

[0098] The embodiment of the present application can ensure that the rotor assembly 2 in the deployed position works normally, and when the rotor assembly 2 is in the retracted position, the ground-to-air bicycle 100 can have a compact structure.

[0099] Please continue to see Figure 4 In some embodiments, the rotor assembly 2 may further include a locking member 24. The locking member 24 is disposed on the connecting shaft 22 of the rotor assembly 2 on one side of the wheel 1, and the locking member 24 is detachably connected to the connecting shaft 22 of the rotor assembly 2 on the other side of the wheel 1. The locking member 24 may be a fastener such as a lock.

[0100] In the embodiment of the present application, when the two rotor assemblies 2 on both sides of the wheel 1 are in the deployed position, the locking member 24 can connect the connecting shafts 22 of the two rotor assemblies 2, thereby fixing the two rotor assemblies 2 in connection, effectively ensuring the stable flight of the ground-to-air bicycle 100 in the air.

[0101] When the rotor assembly 2 is switched to the deployed position, the flight of the ground-to-air bicycle 100 can be controlled in different ways. Figure 2 and Figure 4 In a possible implementation, the ground-air dual-purpose bicycle 100 may include a handlebar 4, and the rider may apply an external force to the handlebar 4 to control the flight of the ground-air dual-purpose bicycle 100 by controlling the handlebar 4. The following describes in detail how to control the flight of the ground-air dual-purpose bicycle 100 using the handlebar 4.

[0102] See also Figure 3 , Figure 5 and Figure 6 When the handlebar 4 is used for flight control, the ground-air dual-purpose bicycle 100 may include not only the handlebar 4, but also a stem body 5 and an adapter assembly 6. The stem body 5 is fixedly connected to the front fork 32. The adapter assembly 6 is connected to the handlebar 4 and the stem body 5. The adapter assembly 6 has an active state and a fixed state. When the rotor assembly 2 is in the deployed position, the adapter assembly 6 can be switched to an active state to rotate relative to the stem body 5 and the handlebar 4; when the rotor assembly 2 is in the retracted position, the adapter assembly 6 can be switched to a fixed state to be fixedly connected to the stem body 5 and the handlebar 4. The controller is electrically connected to the adapter assembly 6.

[0103] The stem body 5 and the front fork 32 are connected as a whole, and the adapter assembly 6 is used as an intermediate connecting member to connect the handlebar 4 and the stem body 5. The adapter assembly 6 has an active state and a fixed state. When the rotor assembly 2 is in the retracted position, the adapter assembly 6 can be switched to a fixed state. The adapter assembly 6 in the fixed state is fixedly connected to the stem body 5 and the handlebar 4 to form an integral rigid structure.

[0104] When the rotor assembly 2 is in the deployed position, the adapter assembly 6 can be switched to an active state, and the adapter assembly 6 can rotate relative to the stem body 5 and the handlebar 4. In other words, the handlebar 4 can rotate relative to the adapter assembly 6, and the adapter assembly 6 can also rotate relative to the stem body 5. In this way, the rider can apply an external force to the handlebar 4 to rotate the handlebar 4 relative to the adapter assembly 6, and the external force is transmitted to the adapter assembly 6 through the handlebar 4 to rotate the handlebar 4 and the adapter assembly 6 relative to the stem body 5.

[0105] The controller is electrically connected to the adapter assembly 6. The controller can control the flight attitude of the rotor assembly 2 based on the rotation of the handlebar 4 relative to the adapter assembly 6, and the rotation of the handlebar 4 and the adapter assembly 6 relative to the stem body 5, thereby achieving flight control of the ground-to-air dual-purpose bicycle 100.

[0106] See also Figure 5 and Figure 6 In some embodiments, the adapter assembly 6 may include an adapter 61, a support shaft 62, a sensor group 63, and a first limit assembly 64. The adapter 61 includes a first section 611 and a second section 612 connected at an angle; the first section 611 is rotatably connected to the stem body 5 around the third axis Z. The support shaft 62 is rotatably connected to the second section 612 around the fourth axis W, and one end of the support shaft 62 away from the second section 612 is fixedly connected to the handlebar 4; the fourth axis W intersects the third axis Z. The sensor group 63 is disposed on the adapter 61 and is electrically connected to the controller, and is used to detect a first rotation angle of the handlebar 4 and the adapter assembly 6 relative to the stem body 5 and a second rotation angle of the handlebar 4 relative to the adapter assembly 6. The first limit assembly 64 is disposed on the adapter 61, and is used to limit the first rotational degree of freedom and the second rotational degree of freedom when the rotor assembly 2 is in the retracted position, and to release the restriction on the first rotational degree of freedom and the second rotational degree of freedom when the rotor assembly 2 is in the deployed position. The first rotational degree of freedom is the rotational degree of freedom of the first section 611 relative to the stem body 5 , and the second rotational degree of freedom is the rotational degree of freedom of the support shaft 62 relative to the second section 612 .

[0107] It is understandable that the first section 611 and the second section 612 of the adapter 61 can be an integral structural member made by stamping, injection molding or casting, or can be separate structural members and fixedly connected by welding, screwing, bonding, etc. The first section 611 is rotatably connected to the stem body 5 around the third axis Z, so that the adapter 61 can rotate relative to the stem body 5. The support shaft 62 is rotatably connected to the second section 612 around the fourth axis W, and one end is fixedly connected to the handlebar 4, so that the handlebar 4 can rotate relative to the adapter 61 through the support shaft 62. The sensor group 63 is arranged between the first section 611 and the second section 612, and can detect the second rotation angle of the handlebar 4 and the support shaft 62 as a whole relative to the adapter 61, and can also detect the first rotation angle of the handlebar 4, the support shaft 62 and the adapter 61 as a whole relative to the stem body 5.

[0108] The sensor group 63 includes a base and a plurality of angle sensors, the base is fixedly connected to the adapter 61, and the angle sensor is mounted on the base. The working principle of the angle sensor can be based on a variety of physical effects, such as the Hall effect, magnetoresistance effect, photoelectric effect, resistance change, etc., that is, the angle sensor can adopt a potentiometer angle sensor, a photoelectric angle sensor, a Hall effect angle sensor, a magnetoresistance effect angle sensor, a rotary transformer angle sensor, etc. Designers can select a suitable angle sensor based on factors such as control accuracy and cost, and the embodiments of the present application do not specifically limit this.

[0109] The first limit assembly 64 is disposed on the adapter 61, and is used to release the restriction on the rotational freedom of the first section 611 relative to the stem body 5 and the rotational freedom of the support shaft 62 relative to the second section 612 when the rotor assembly 2 is in the deployed position, so that the rider can apply external force to the handlebar 4, and control the flight of the ground-to-air bicycle 100 by controlling the handlebar 4. Of course, when the rotor assembly 2 is in the retracted position, the first limit assembly 64 is also used to impose restrictions on the rotational freedom of the first section 611 relative to the stem body 5 and the rotational freedom of the support shaft 62 relative to the second section 612, so that the handlebar 4, the adapter assembly 6 and the stem body 5 become an integral rigid structure, so that the rider can control the ground-to-air bicycle 100 to ride on the ground through the handlebar 4.

[0110] For example, see Figure 6 The first limit assembly 64 may include a first connector 641 and a second connector 642. The first connector 641 is disposed on the first section 611, and the second connector 642 is disposed on the second section 612. When the rotor assembly 2 is located at the folded position, the first connector 641 is plug-connected with the first section 611 and the handlebar body 5, and the second connector 642 is plug-connected with the second section 612 and the support shaft 62. The handlebar 4, the adapter assembly 6 and the handlebar body 5 are an integral rigid structure. When the rotor assembly 2 is located at the unfolded position, the first connector 641 is disengaged from the handlebar body 5, and the second connector 642 is disengaged from the support shaft 62. The first section 611 can rotate relative to the handlebar body 5, and the support shaft 62 can rotate relative to the second section 612.

[0111] The controller is electrically connected to the sensor group 63. For the rotor assembly 2 in the deployed position, the controller can obtain the first rotation angle and the second rotation angle detected by the sensor group 63, and control the flight attitude of the rotor assembly 2 according to the first rotation angle and the second rotation angle. For example, when the handlebar 4 and the support shaft 62 as a whole swing up and down around the fourth axis W relative to the adapter 61, the controller can control the left and right lateral movement of the ground-to-air bicycle 100 during flight by obtaining the second rotation angle. When the handlebar 4, the support shaft 62 and the adapter 61 as a whole rotate clockwise or counterclockwise around the third axis Z relative to the stem body 5, the controller can control the left and right heading of the ground-to-air bicycle 100 during flight by obtaining the first rotation angle.

[0112] In order to make the handlebar 4 automatically return to the center position, reduce the number of times and strength that the rider adjusts the rotor assembly 2 through the handlebar 4, and make the process of controlling the flight easier and more comfortable, in some embodiments, the adapter assembly 6 may also include a first elastic reset member 71 and / or a second elastic reset member 72. The first elastic reset member 71 is arranged on the support shaft 62. When the first driving torque that drives the handlebar 4 to rotate around the third axis Z is eliminated, the first reset torque generated by the first elastic reset member 71 can drive the handlebar 4 to reset. The second elastic reset member 72 is arranged on the stem body 5. When the second driving torque that drives the handlebar 4 and the adapter assembly 6 to rotate around the fourth axis W is eliminated, the second reset torque generated by the second elastic reset member 72 can drive the handlebar 4 and the adapter assembly 6 to reset.

[0113] The first elastic reset member 71 and the second elastic reset member 72 may be a torsion spring, a spring sheet, etc. Figure 6 The first elastic reset member 71 can be arranged at one end of the support shaft 62 close to the adapter 61, and the second elastic reset member 72 can be arranged at one end of the stem body 5 close to the adapter 61. When the first elastic reset member 71 is a torsion spring, it can be sleeved on the support shaft 62, and the two torsion arms of the torsion spring can abut against the adapter 61. The second elastic reset member 72 is similar to the first elastic reset member 71, and will not be described in detail here.

[0114] See also Figure 5 and Figure 6 The main frame 31 includes a head tube 311 and a down tube 312. The down tube 312 is connected to the head tube 311, and the head tube 311 is sleeved on the stem body 5 and can rotate relative to the stem body 5. In other words, the stem body 5 can rotate relative to the head tube 311.

[0115] When the rider applies external force to the handlebar 4, in order to prevent the handlebar 4, the adapter assembly 6 and the stem body 5 from rotating as a whole relative to the head tube 311 under the action of friction, thereby affecting the accuracy of the rider controlling the flight of the dual-purpose ground-air bicycle 100 through the handlebar 4, the main frame 31 of the embodiment of the present application further includes a second limit assembly 3122, and the down tube 312 is provided with a first connecting member 3121, and the stem body 5 is provided with a second connecting member 321. The second limit assembly 3122 is provided on one of the first connecting member 3121 and the second connecting member 321, and is used to limit the rotational freedom of the stem body 5 relative to the head tube 311 when the rotor assembly 2 is in the extended position, and to release the restriction on the rotational freedom of the stem body 5 relative to the head tube 311 when the rotor assembly 2 is in the retracted position.

[0116] In the embodiment of the present application, when the rotor assembly 2 is in the deployed position, the second limit assembly 3122 can limit the rotational freedom of the stem body 5 relative to the head tube 311, which can effectively prevent the handlebar 4, the adapter assembly 6 and the stem body 5 from rotating relative to the head tube 311 as a whole under the action of friction, thereby preventing the rider from affecting the accuracy of controlling the flight of the ground-to-air dual-purpose bicycle 100 through the handlebar 4. The second limit assembly 3122 may include at least one third connector, which is disposed on one of the first connector 3121 and the second connector 321. When the rotor assembly 2 is in the deployed position, the third connector is plug-connected with the other of the first connector 3121 and the second connector 321.

[0117] When the rotor assembly 2 is in the folded position, the second limit assembly 3122 can also release the restriction on the rotational freedom of the stem body 5 relative to the head tube 311, for example, the third connector is disconnected from the other of the first connector 3121 and the second connector 321. In this way, the rider can drive the adapter assembly 6, the stem body 5, the front fork 32 and the front wheel 11 through the handlebar 4 to control the ground-to-air dual-purpose bicycle 100 to ride on the ground.

[0118] See also Figure 5 In some embodiments, the handlebar 4 may further include a handlebar body 41 and a wave wheel switch 42. The handlebar body 41 is connected to the adapter assembly 6, and the wave wheel switch 42 is disposed on the handlebar body 41 and is electrically connected to the controller. The rider can control the ascent, descent, hovering, etc. of the ground-to-air dual-purpose bicycle 100 during flight by controlling the rotation of the wave wheel switch 42.

[0119] In addition, please continue to see Figure 5The handlebar 4 may further include a handle assembly 43, which is rotatably connected to the handlebar body 41 and electrically connected to the controller. The handle assembly 43 includes a movable handle and an angle sensor, the movable handle can be transmitted relative to the handlebar body 41, and the angle sensor can detect the rotation angle of the movable handle and send the rotation angle to the controller. The controller can control the forward and backward movements of the ground-to-air dual-purpose bicycle 100 during flight through the rotation angle.

[0120] In addition to the above-mentioned control of the ground-air dual-purpose bicycle 100 by controlling the handlebar 4, see Figure 5 In another possible implementation, the ground-air dual-purpose bicycle 100 may further include a remote control device 8 , which is communicatively connected to the controller, and the rider may implement flight control of the ground-air dual-purpose bicycle 100 through the remote control device 8 .

[0121] like Figure 5 As shown, the remote control device 8 can be detachably arranged on the adapter assembly 6, for example, a clamp can be used to clamp the remote control device 8. When the rider needs to use the remote control device 8 to control the flight of the ground-air dual-purpose bicycle 100, the rider can take the remote control device 8 out of the clamp and remotely control the flight of the ground-air dual-purpose bicycle 100 through the remote control device 8.
