Abstract
Description
Technical Field
[0001] The invention relates to the technical field of two-wheeled vehicles, in particular to a fully enclosed two-wheeled vehicle with eccentric floating wheels and a control method thereof. Background Art
[0002] The future development of urban transportation is space, especially in Beijing, Shanghai and Guangzhou, where traffic congestion is the norm during rush hour every day. The fundamental reason is that a single-person car takes up the space of four people. The present invention is to launch an eccentric floating wheel fully enclosed two-wheeled vehicle with car attributes created for single-person travel, which is 1 / 6 of the volume of an ordinary car and fills the gap in the market for fully enclosed two-wheeled vehicles for single-person travel. The main technical obstacle to fully enclosed two-wheeled vehicles is the balance of the vehicle after an emergency stop occurs due to an accident during driving. In related technologies, the balance of two-wheeled vehicles is mainly controlled by controlling the lifting of auxiliary support wheels or using a constant speed automatic control of the lifting of auxiliary support wheels and adopting high-speed motion gyroscopes. Due to the landing distance between the lifting of the auxiliary support wheels and the ground and the minimum landing time required within the vehicle's extreme tilt angle, especially when the auxiliary support wheels have a hard impact and fall to the ground during driving, inertia dumping is likely to occur. Therefore, this landing gear-type support cannot safely and reliably meet the vehicle balance requirements of the two-wheeled vehicle after an emergency stop occurs due to an accident during driving. The use of high-speed motion gyroscopes to maintain vehicle balance has large device size, high cost, and requires additional continuous power to maintain high-speed gyroscope movement. The vehicle door and window system uses separate and cumbersome components.
[0003] It is these safety reasons and the factors contrary to the lightness of two-wheeled vehicles that hinder the commercialization of fully enclosed two-wheeled vehicles. Therefore, it is necessary to design a fully enclosed two-wheeled vehicle with an eccentric floating wheel and a control method thereof to overcome the above problems. Summary of the invention
[0004] The embodiment of the present invention provides an eccentric floating wheel fully enclosed two-wheeled vehicle and a control method thereof, so as to solve the problems in the related art that the fully enclosed two-wheeled vehicle cannot safely and reliably cope with the emergency stop of the two-wheeled vehicle within the vehicle's extreme tilt angle during driving because the minimum time required for the auxiliary support wheels to land cannot be met, especially when the auxiliary wheels have a hard impact at a distance during driving and fall to the ground, inertia dumping occurs easily, the space occupied is large, the cost is high, and additional continuous reliance on electricity is required to maintain the balance of the vehicle. The vehicle door and window system adopts an integrated convenient component.
[0005] In a first aspect, a fully enclosed two-wheeled vehicle with an eccentric floating wheel and a control method thereof are provided, including a foot brake connecting rod assembly, a door and window integrated sliding door component, and an eccentric floating wheel assembly, which includes: a worm gear motor pipe clamp sleeve, a suspension arm joint bearing end respectively assembled by a wire tube, a double tube clamp, a short sleeve, an eccentric floating wheel, a middle sleeve, and a long shaft, the suspension arm bearing end is respectively fixed on the left and right side plate frames of the rear wheels of the vehicle, the suspension arm is twisted and changed with external force within the rollover range of the vehicle, and the floating wheel connected to it floats along the road surface at zero distance, and when the suspension arm is about to twist and change and the floating wheel at the side bend of the vehicle automatically becomes the third point support.
[0006] The foot brake linkage assembly with seat bearings are fixed on the left and right side panels of the rear wheels of the vehicle by studs respectively. By guiding the position of the suspension arm where the concave pulley is located by the foot pressure linkage assembly, the suspension arm distortion range can be changed from large to stop and self-locked through the tension spring and the components. The hand brake inching trigger signal can be defined to drive the eccentric floating wheel assembly worm gear motor to change the position of the eccentric block through gears to return the floating wheel to its initial state and define another hand brake inching trigger signal to control the eccentric floating wheel assembly worm gear motor to control the eccentric block through gears to allow the floating wheel to obtain four-point support for the vehicle.
[0007] In some embodiments, the eccentric floating wheel assembly includes a worm gear motor with a Hall sensor, a wheel housing, a large bearing, an eccentric block, a small bearing, a gear, and a suspension arm component. The large bearing is placed in the wheel housing, the eccentric block is placed in the large bearing, and the small bearing is placed in the eccentric block hole. The gear is concentric with the eccentric hole and fixed by a stud.
[0008] In some embodiments, the eccentric floating wheel fully enclosed two-wheeled vehicle and the control method thereof, the worm gear motor pipe clamp sleeve and the suspension arm joint bearing end are respectively assembled by a wire tube, a double tube clamp, a short sleeve, an eccentric floating wheel, a middle sleeve, and a long shaft. The suspension arm bearing end is respectively fixed on the left and right side plate frames of the rear wheels of the vehicle. The suspension arm and the floating wheel connected thereto are twisted and changed with external force within the rollover range of the vehicle and float along the road surface at zero distance. When the suspension arm twists and changes and stops at the side bend of the vehicle when the rollover is imminent, the floating wheel automatically becomes the third point support.
[0009] In some embodiments, the eccentric floating wheel fully enclosed two-wheeled vehicle and the control method thereof can define a handbrake momentary trigger signal to drive the eccentric floating wheel assembly worm gear motor to change the position of the eccentric block via gears to return the floating wheel to an initial state, and define another handbrake momentary trigger signal to control the eccentric floating wheel assembly worm gear motor to control the eccentric block via gears to allow the floating wheel to obtain four-point support for the vehicle.
[0010] In some embodiments, the eccentric floating wheel fully enclosed two-wheeled vehicle and the control method thereof can change the distortion range of the suspension arms when the vehicle is about to roll over and the corresponding vehicle tilt angle by adjusting the distance between the suspension arms and adding adjustment blocks.
[0011] In some embodiments, the eccentric floating wheel fully enclosed two-wheeled vehicle and the control method thereof, when the concave pulley is at the uppermost end of the suspension arm through the foot brake connecting rod assembly, the suspension arm distortion change is the largest, and the vehicle can obtain the maximum safe tilt bending angle, and when the guiding concave pulley is at the lowermost end of the suspension arm, the distortion change stops and is automatically locked through the tension spring and the components.
[0012] In some embodiments, the eccentric floating wheel fully enclosed two-wheeled vehicle and control method thereof, a door and window integrated sliding door component, includes a door and window guard rod with a ball bearing placed above the door and window and fixed to the vehicle body, with the other end suspended in front of the door and window.
[0013] In some embodiments, the described eccentric floating wheel fully enclosed two-wheeled vehicle and control method thereof, the door and window integrated sliding door component, which includes a DC reduction motor, a door and window guard bar with a ball bearing, a convex pulley, a double-axis roller slide rail, a roller, a sensor switch 1, a sensor switch 2, a door and window frame with a sealing groove, and a transparent door and window material, which can realize a fully open door or a slightly open window.
[0014] Secondly, a fully enclosed two-wheeled vehicle with an eccentric floating wheel and a control method thereof are provided, including an eccentric floating wheel assembly which is fixed on a wire tube by a worm gear motor pipe clamp sleeve, the worm gear motor leads and the Hall sensor leads enter from the left hole and the right hole on the wire tube, and finally exit from the wire tube exit hole through a double tube clamp and a short sleeve to make the worm gear motor gear match the eccentric floating wheel gear, the suspension arm joint bearing ends are respectively connected to the eccentric floating wheel by a short sleeve, and the joint assembly is completed through a middle sleeve and a long shaft, the suspension arm joint bearing ends are respectively connected to the eccentric floating wheel, and the suspension arm bearing ends are respectively fixed on the left and right side plate frames of the rear wheels of the vehicle, the suspension arm changes with the external force within the rollover range of the vehicle, and the floating wheel connected to it floats along the road surface at zero distance, and when the suspension arm changes with the distortion when the rollover is imminent and the floating wheel at the side bend of the vehicle automatically becomes the third point support.
[0015] In the third aspect, a fully enclosed two-wheeled vehicle with eccentric floating wheels and a control method thereof are provided, including a foot brake connecting rod assembly with a seat bearing fixed to the left and right side plate frames of the rear wheel through a stud, the two ends of the open frame rotate in the seat bearing, and the two feet of the open frame are semicircular hooks. When the current pedal is pressed down, the open frame is pulled by the connecting rod to produce a clockwise rotation, and the concave pulleys at both ends of the open frame slide downward along the suspension arm to the lowest end, and then the semicircular hooks are tightly buckled on the sleeve between the two suspension arms. The suspension arm stops twisting and changes, and self-locks under the tightening action of the sharp angle of the tension spring, and then the pedal is pressed down to generate thrust driven by the connecting rod. The open frame rotates counterclockwise, and the concave pulleys at both ends of the open frame slide upward along the suspension arm to the uppermost end and then self-lock under the action of the sharp-angle tension of the tension spring. The suspension arm obtains the maximum twistable change, that is, the maximum safe tilt bending angle that the vehicle can obtain. By switching and controlling the front pedal and the rear pedal, the concave pulley can be guided to stay at the position of the suspension arm to correct the tilt angle state of the vehicle within the rollover range. When the vehicle is driving, the weight of the vehicle is mainly borne by the front and rear wheels, so this method of guiding the concave pulley with a foot brake linkage structure is a micro-force structural component control similar to the micro-force control of an electronic lock.
[0016] A handbrake inching trigger signal can be defined to drive the eccentric floating wheel assembly, the worm gear motor changes the position of the eccentric block through gears to make the floating wheel return to the initial state, that is, the place where the eccentric hole is closest to the ground. The position signal is fed back to the motor controller through the Hall sensors on the worm gear motors. Another defined handbrake inching trigger signal triggers the motor controller to generate a stall current under the external load to reach the set value. The motor self-stop characteristic controls the worm gear motor through gears to control the eccentric block so that the floating wheel is fully loaded to fill the depression in the road surface, so that the vehicle obtains four-point support on the road surface. Since the wheel shell is a solid tire with a built-in large bearing, the eccentric block is placed in the large bearing, so the change in the position of the eccentric block does not affect the sliding of the solid tire and the road surface. At the same time, the change in the position of the eccentric block is a continuous curve method to raise or lower the floating wheel, thereby avoiding the disadvantage of the landing gear-type lifting auxiliary support wheel landing during vehicle driving because there is a hard impact and landing at a distance, which is easy to cause the inertia dumping disadvantage.
[0017] The definable handbrake inching trigger signal can be realized according to personal habits by simply exchanging the handbrake inching trigger signal output connections. Since the handbrake is a routine driving habit operation, this control method allows the driver to adapt without learning. After defining the handbrake inching trigger signal to control the floating wheel to return to the initial position, clicking the handbrake again will not change the initial state of the floating wheel due to the positioning of the Hall sensor. This control method maintains the same habit as daily driving operations, so the driver can operate it without additional learning.
[0018] A fourth aspect provides the above-mentioned eccentric floating wheel fully enclosed two-wheeled vehicle and a control method thereof, including a door and window integrated sliding door component, which includes a door and window frame with a sealing groove, an organic perspective material combined into one through a window sealing strip and the sealing groove door and window frame, a groove is opened at the bottom of the sealing groove door and window frame to facilitate the positioning and movement of the convex pulley, a ball bearing door and window guard rod is arranged above the sealing groove door and window frame, one end of which is fixed to the vehicle body and the other end is suspended in the air in front of the sealing groove door and window frame, rollers and racks are installed at the lower back of the bottom of the sealing groove door and window frame, the rollers are arranged in a double-axis roller slide rail for positioning and sliding, the sealing groove door and window frame rack is driven to move by the gear of the reduction motor, the door and window frame foam sealing strip and the door frame side foam sealing strip are sealed by mutual extrusion through the limit control of the sensor switch, and the self-locking characteristics of the reduction motor are utilized to control the reduction motor to stop at any position to achieve the convenient effect of fully opening the door or slightly opening the window.
[0019] The beneficial effects brought about by the technical solution provided by the present invention include:
[0020] The embodiment of the present invention provides an eccentric floating wheel fully enclosed two-wheeled vehicle and a control method thereof. Within the rollover range, the suspension arm twists and changes with external force, and the floating wheel connected thereto floats along the road surface at zero distance. When the rollover is imminent, the suspension arm twists and changes, and the floating wheel that stops at the side bend of the vehicle automatically becomes the third point support, thereby solving the problem of inertial tipping that is easy to occur due to the landing distance between the auxiliary support wheel and the ground and the minimum landing time required within the vehicle's extreme tilt angle, especially when the auxiliary support wheel has a hard impact and lands during driving, and the vehicle balance after emergency stop.
[0021] The handbrake trigger signal triggers the application of the motor controller, which is subjected to external force load and generates a stall current that reaches the set value. The motor's self-stop feature controls the worm gear motor and controls the eccentric block through the gears to allow the floating wheel to be fully loaded to fill the depression in the road surface so that the vehicle can obtain four-point support, solving the problem of using a high-speed motion gyroscope due to its large size, high cost, and the need for additional continuous power to maintain the high-speed motion of the gyroscope to maintain vehicle balance.
[0022] The vehicle door and window system adopts a reduction motor to directly move and control through gear racks. The door and window frame foam sealing strips and the door frame side foam sealing strips are sealed by squeezing each other. The self-locking characteristics of the reduction motor can be used to arbitrarily position the integrated door and window, and the fully open is the door and the slightly open is the window. This convenient integrated door and window component solves the problem of existing vehicle sliding doors having to use cumbersome door and window separation components because they cannot be positioned on the way, filling the gap for the industrialization and promotion of safe and cheap micro fully enclosed single-person vehicles.

DETAILED DESCRIPTION
[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.
[0047] See also Fig. 9 , Fig.10 , Fig.13As shown, an eccentric floating wheel fully enclosed two-wheeled vehicle and a control method thereof provided by an embodiment of the present invention include an eccentric floating wheel assembly ①, which is fixed by a worm gear motor pipe clamp sleeve 9 on a wire tube 107, and the leads of the worm gear motor 41, 51 and the Hall sensor 6 enter from the left wire hole 105 and the right wire hole 108 on the wire tube 107, and finally exit from the wire outlet hole 106 through a double pipe clamp 109 and connected to a short sleeve 102 so that the gears of the worm gear motor 41, 51 are matched with the gears 4 of the eccentric floating wheel ⑷, ⑸, and the suspension arm joint bearing The ends 8 are connected by short sleeves 102 and eccentric floating wheels ⑷ and ⑸, and the joint assembly is completed through the middle sleeve 103 and the long shaft 101. The suspension arm joint bearing ends 8 are connected to the eccentric floating wheels ⑷ and ⑸, and the suspension arm bearing ends 7 are fixed on the left 009 and right 008 side plate frames of the rear wheels of the vehicle. Within the rollover range of the vehicle, the suspension arm ⑹ changes with the twisting of external force and the floating wheels ⑷ and ⑸ connected thereto float along the road surface at zero distance. When the suspension arm is about to roll over, the twisting change of the suspension arm ⑹ stops and the floating wheels ⑷ and ⑸ at the side bend of the vehicle automatically become the third point support.
[0048] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 , Fig.11 , Fig.12 , Fig.13 As shown, an eccentric floating wheel fully enclosed two-wheeled vehicle and a control method thereof provided by an embodiment of the present invention include a foot brake connecting rod assembly ②, a seat bearing 203 is fixed to the left 009 and right 008 side plate frames of the rear wheel through a stud, the two ends of the open frame 209 rotate in the seat bearing 203, and the two feet of the open frame 209 are semicircular hooks. When the current pedal 201 is pressed down, the open frame 209 is pulled by the connecting rod 207 to produce a clockwise rotation, and the concave pulleys 208 at both ends of the open frame 209 slide downward along the suspension arm ⑹ to the lowest end, and then the semicircular hooks are tightly fastened to the sleeve 103 between the two suspension arms ⑹. The suspension arm ⑹ stops twisting and changes, and is self-locked under the acute angle tension of the tension spring 210, and then the pedal rod 202 is pressed down to produce a push The force is driven by the connecting rod 207 to drive the open frame 209 to rotate counterclockwise. The concave pulleys 208 at both ends of the open frame 209 slide upward along the suspension arm (6) to the uppermost end and then self-lock under the acute angle tension of the tension spring 210. The suspension arm (6) obtains the maximum twistable change, that is, the maximum safe tilt bending angle that the vehicle can obtain. By switching and controlling the front pedal 201 and the rear pedal 202, the concave pulley 208 can be guided to stay at the position of the suspension arm (6) to correct the tilt angle state of the vehicle within the rollover range. When the vehicle is driving, the weight of the vehicle is mainly borne by the front wheel 003 and the rear wheel 002. Therefore, the way in which this foot brake connecting rod structure guides the concave pulley 208 is a micro-force structural component control similar to the micro-force control of the electronic lock.
[0049] The handbrake 004, 005 inching trigger signal can be defined to drive the eccentric floating wheel assembly ⑷, ⑸ worm gear motor 41, 51 to change the position of the eccentric block 43, 53 through the gear 4 to make the floating wheel ⑷, ⑸ return to the initial state, that is, the place where the eccentric hole is closest to the ground. The position signal output by the Hall sensor 6 on each of the worm gear motors 41, 51 is fed back to the motor controller for control. The handbrake 004, 005 inching trigger signal defined by the other definition triggers the application motor controller to generate a stall current under the external load to reach the set value, and the motor self-stop characteristics control the worm gear motor 41, 51 The gear 4 controls the eccentric blocks 43 and 53 to allow the floating wheels ⑷ and ⑸ to be fully loaded and fill the depressions on the road surface so that the vehicle can obtain four-point support on the road surface. Since the wheel shell 2 is a solid tire with a built-in large bearing 1, the eccentric blocks 43 and 53 are placed in the large bearing 1, so the position change of the eccentric blocks 43 and 53 does not affect the sliding of the solid tire 2 and the road surface. At the same time, the position change of the eccentric blocks 43 and 53 is a continuous curve method to raise or lower the floating wheels ⑷ and ⑸, thereby avoiding the disadvantage of the landing gear type lifting auxiliary support wheel being easily caused by the inertia tipping when the vehicle lands at a distance during driving.
[0050] The handbrake 004, 005 inching trigger signals can be defined according to personal habits by simply exchanging the handbrake 004, 005 inching trigger signal output connections. Since the handbrake 004, 005 are conventional driving habit operations, this control method allows the driver to adapt without learning. After defining the handbrake 004, 005 inching trigger signals to control the floating wheels ⑷, ⑸ to return to the initial position, clicking the handbrake 004, 005 again will not change the initial state of the floating wheels ⑷, ⑸ due to the positioning of the Hall sensor 6. This control method maintains the same habits as daily driving operations and can be operated without additional learning.

Through the limit control of the sensor switches 311 and 313, the foam sealing strip 305 of the door and window frame 303 and the foam sealing strip 007 on the side of the vehicle door frame squeeze and seal each other. The self-locking characteristic of the reduction motor 312 is utilized to control the reduction motor 312 to stop at any position to achieve the convenient effect of fully opening the door or slightly opening the window.
