Description

Technical Field

[0001] This utility model relates to the field of drive wheel technology, specifically a clutch-type drive wheel for electric scooters. Background Technology

[0002] Currently, electric scooters, as a convenient personal transportation tool, are widely used for daily commuting and short-distance travel. Existing electric scooters generally use a motor to directly drive the tires for propulsion, and control direction via a servo motor or manual steering mechanism. While this structure can meet basic riding and steering functions, it still has significant shortcomings in terms of overall integration and power control.

[0003] In typical designs, the drive motor is usually directly connected to the wheels via a fixed gear or belt drive, resulting in a simple power transmission path and a lack of an effective clutch switching mechanism. Once the motor is continuously outputting power, the wheels are in a forced-drive state, which is not conducive to cutting off power during downhill driving, coasting, or stopping. At the same time, some existing devices, in order to increase steering flexibility, only have simple rotating hinge points at the wheel frame ends, resulting in a loose overall structure and insufficient driving stability.

[0004] On the other hand, existing drive wheel assemblies generally lack control structures for power engagement and disengagement. When the motor needs to be disconnected or reconnected, it is often achieved through manual power cut-off or mechanical friction braking. This not only easily leads to motor no-load losses and energy waste, but also generates shocks during the switching process, reducing vehicle safety and service life. In addition, because existing devices have not integrated the drive and steering mechanisms, their structures are complex, have low integration, and are relatively cumbersome to maintain and debug.

[0005] Therefore, there is an urgent need for a compact electric scooter drive wheel with clutch control function and integrated drive and steering design to solve the above technical problems and improve the overall operating efficiency and safety reliability of the vehicle. Utility Model Content

[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0007] Therefore, the technical solution adopted by this utility model is as follows: a clutch-type electric scooter drive wheel, including a drive base, a movable wheel, and a clutch control assembly. A steering wheel frame is rotatably mounted on the bottom surface of the drive base, and the movable wheel is rotatably mounted on the surface of the steering wheel frame. A drive shaft is passed through the surface of the steering wheel frame, and a driven gear plate that meshes with the bottom end of the drive shaft is fixedly mounted on the surface of the movable wheel. A drive motor and a steering servo are provided inside the drive base. The output end of the steering servo is connected to the steering wheel frame to drive the movable wheel to deflect and achieve steering. The clutch control assembly includes a rocker arm, a drive cylinder, a gear shaft, clutch teeth, and a control core rod, which can achieve the engagement and disengagement of power between the drive motor and the movable wheel by controlling the raising and lowering of the control core rod.

[0008] In a preferred embodiment, the steering wheel carrier surface is further configured with forks symmetrically arranged on both sides of the moving wheel for stable support of the moving wheel. The steering wheel carrier is axially rotatable on the bottom surface of the drive unit, and the rotation axis of the moving wheel is perpendicular to the fork surface. Specifically, this structure ensures the stability of the moving wheel during high-speed operation and steering, improving the overall vehicle handling.

[0009] In a preferred embodiment, the gear shaft is further configured coaxially with the steering wheel frame, and the output of the drive motor is sequentially driven through the clutch gear, gear shaft, transmission shaft, and driven gear plate to achieve the rotation of the moving wheel. Specifically, this structure optimizes the power transmission path, resulting in higher transmission efficiency and improved dynamic stability of the scooter during operation.

[0010] In a preferred embodiment, the drive housing is further configured with a sensing component inside for monitoring the movement of the output rod of the drive cylinder. The drive cylinder and the control rod are rotatably mounted at both ends of the rocker arm, and the control rod achieves lifting and lowering movement when the rocker arm deflects. Specifically, this configuration enables real-time monitoring and feedback of the clutch state, improving the accuracy and safety of clutch control.

[0011] In a preferred embodiment, the abutment ball is further configured such that it is movably sleeved inside the through hole on the surface of the gear shaft, and the sum of the radius of the control core rod and the diameter of the abutment ball is equal to the distance from the inner side of the meshing groove to the center of the clutch gear shaft, and this sum is greater than the diameter of the gear shaft. Specifically, this structure ensures that the abutment ball can accurately enter or exit the meshing groove under the action of the control core rod, thereby achieving stable clutch engagement and disengagement.

[0012] In a preferred embodiment, the inner side of the gear shaft is further configured with a limiting groove to guide the abutment ball to slide radially toward the through hole on the surface of the gear shaft. Specifically, this structure prevents the abutment ball from shifting or getting stuck during the sliding process, ensuring the reliability of the clutch control.

[0013] In a preferred embodiment, the drive cylinder is further configured as a hydraulic cylinder or an electric push rod, capable of outputting reciprocating linear displacement to drive the rocker arm to deflect, thereby causing the control core rod to achieve lifting and lowering motion inside the gear shaft. Specifically, this solution improves the automation level and response speed of clutch switching, reduces manual intervention, and enhances the intelligence level of system operation.

[0014] In a preferred embodiment, the control core rod is further configured such that its end has a beveled portion that abuts against a stop ball. During the lifting and lowering movement of the control core rod, the stop ball is pushed radially into or out of the meshing groove, thereby achieving the engagement and disengagement of the clutch teeth and the gear shaft. Specifically, this structure achieves reliable power switching through the mechanical bevel engagement, effectively improving the adaptability and operational stability of the electric scooter under various working conditions.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, by setting up a coordinated transmission structure of drive base, steering wheel frame, drive motor, transmission shaft and driven gear plate, the output power of drive motor can be reliably transmitted to moving wheel through clutch teeth and gear shaft, which not only ensures the driving efficiency of electric scooter, but also achieves flexible steering by driving steering wheel frame to deflect through steering servo, effectively improving the handling performance and running stability of the whole vehicle.

[0017] 2. In this utility model, through the innovative structural design of the clutch control component, the controllable engagement and disengagement of power transmission between the drive motor and the moving wheel are achieved by utilizing the cooperation of the rocker arm, drive cylinder, control core rod, abutment ball, and meshing groove. This design not only cuts off power when needed, avoiding motor no-load loss, but also quickly completes power switching during operation, improving the reliability and response speed of clutch operation, thereby significantly improving the adaptability and safety of the electric scooter under different working conditions.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a clutch-type electric scooter drive wheel.

[0030] Combination Figures 1-5 As shown, the present invention provides a clutch-type electric scooter drive wheel, including a drive base 100, a moving wheel 200, and a clutch control assembly 300.

[0031] A steering wheel frame 110 is rotatably mounted on the bottom surface of the drive base 100, and the movable wheel 200 is rotatably mounted on the surface of the steering wheel frame 110. A rotatable drive shaft 120 is provided through the surface of the steering wheel frame 110. A driven gear 210 that meshes with the bottom end of the drive shaft 120 is fixedly mounted on the surface of the movable wheel 200. A drive motor 130 and a steering servo 140 are fixedly mounted on the inner side of the drive base 100. The output end of the steering servo 140 is connected to the surface of the steering wheel frame 110 for driving the steering wheel frame 110 and the movable wheel 200 to deflect, thereby achieving steering in the direction of travel.

[0032] The clutch control assembly 300 includes a rocker arm 310, a drive cylinder 320, a gear shaft 330, a clutch gear 340, and a control core rod 350. The control core rod 350 is rotatably mounted on one end of the rocker arm 310, and the other end of the rocker arm 310 is rotatably connected to the output end of the drive cylinder 320. A support rod 311 is rotatably mounted on the surface of the rocker arm 310. The support rod 311 is fixed to the inner side of the drive base 100 and located in the middle of the rocker arm 310, used to support the stability of the rocker arm 310 during deflection. The gear shaft 330 is rotatably mounted on the inner side of the drive base 100, and its bottom end is provided with a gear that meshes with the top end of the transmission shaft 120. The clutch gear 340 is rotatably sleeved on the surface of the gear shaft 330, and the outer periphery of the clutch gear 340 meshes with the output end of the drive motor 130 for transmission. The surface of the gear shaft 330 is provided with several through holes, and its inner side is provided with abutment balls 331 arranged corresponding to the through holes. The inner side of the clutch tooth 340 is provided with several meshing grooves 341 arranged corresponding to the abutment balls 331. The control core rod 350 is slidably sleeved on the inner side of the gear shaft 330 and is used to control the engagement or disengagement of the abutment balls 331 and the meshing grooves 341.

[0033] In a preferred embodiment, the surface of the steering wheel frame 110 is provided with forks symmetrically arranged on both sides of the movable wheel 200 to support the rotation of the movable wheel 200. The steering wheel frame 110 is axially mounted vertically on the bottom surface of the drive base 100, and the rotation axis of the movable wheel 200 is perpendicular to the surface of the forks. This arrangement ensures higher stability and reliability of the movable wheel 200 during driving and steering.

[0034] In another embodiment, the gear shaft 330 is coaxially arranged with the steering wheel frame 110. The output end of the drive motor 130 is sequentially connected to the clutch gear 340, the gear shaft 330, the transmission shaft 120, and the driven gear plate 210, thereby driving the rotation of the moving wheel 200 and realizing the driving of the electric scooter. This structure ensures the high efficiency and compactness of the power transmission path.

[0035] In another embodiment, a sensing component is provided on the inner side of the drive base 100 to monitor the movement of the output rod of the drive cylinder 320. The drive cylinder 320 and the control core rod 350 are respectively rotatably mounted at both ends of the rocker arm 310. When the rocker arm 310 deflects, the control core rod 350 moves up and down inside the gear shaft 330, thereby controlling the abutment ball 331 and the meshing groove 341. Through the monitoring of the sensing component, the clutch status can be fed back in real time, improving control accuracy.

[0036] In a further embodiment, the abutment ball 331 is movably sleeved inside the through hole on the surface of the gear shaft 330. The sum of the radius of the control core rod 350 and the diameter of the abutment ball 331 is equal to the distance from the inner side of the meshing groove 341 to the axis of the clutch tooth 340, and the sum of the radius of the control core rod 350 and the diameter of the abutment ball 331 is greater than the diameter of the gear shaft 330. This structure ensures that the abutment ball 331 can reliably enter or exit the meshing groove 341 under the drive of the control core rod 350, achieving stable clutch engagement and disengagement.

[0037] In another embodiment, the inner side of the gear shaft 330 is provided with a limiting groove to guide the abutment ball 331 to slide radially toward the through hole on the surface of the gear shaft 330. This structure prevents the abutment ball 331 from shifting or jamming during movement, ensuring the stability of the clutch control.

[0038] In a further embodiment, the drive cylinder 320 is a hydraulic cylinder or an electric push rod, capable of outputting reciprocating linear displacement to drive the rocker arm 310 to deflect, thereby causing the control core rod 350 to perform radial lifting and lowering motion inside the gear shaft 330. This arrangement ensures the automation and response speed of clutch control.

[0039] In another embodiment, the end of the control core rod 350 is provided with a beveled portion, which abuts against the abutment ball 331. When the control core rod 350 moves up and down, the beveled portion pushes the abutment ball 331 to slide radially, causing it to enter or exit the meshing groove 341, thereby achieving the engagement and disengagement of the clutch tooth 340 and the gear shaft 330. This structure enables reliable switching of power transmission, ensuring the normal operation of the scooter under different working conditions.

[0040] In summary, the clutch-type electric scooter drive wheel of this utility model achieves driving movement, flexible steering, and reliable clutch control through the coordinated action of the drive base 100, the moving wheel 200, the steering servo 140, the drive motor 130, and the clutch control assembly 300. Those skilled in the art will understand that various changes or modifications can be made without departing from the spirit and scope of this utility model, and all such changes or modifications fall within the protection scope of this utility model.

[0041] Working principle and usage process of this utility model:

[0042] This invention relates to a clutch-type electric scooter. Through the coordinated operation of the drive base 100, the moving wheel 200, and the clutch control assembly 300, the scooter achieves motor-driven movement, servo steering control, and clutch switching functions. Its working principle is as follows:

[0043] The output end of the drive motor 130 transmits power to the gear shaft 330 through meshing with the clutch gear 340. The gear shaft 330 meshes with the transmission shaft 120, further driving the driven gear plate 210 mounted on the steering wheel frame 110 to rotate, thereby driving the moving wheel 200 to rotate, realizing the forward or backward movement of the electric scooter.

[0044] The steering servo 140 is located inside the drive unit 100, and its output end is connected to the steering wheel frame 110. When the steering servo 140 is activated, it can drive the steering wheel frame 110 to deflect, thereby changing the direction of travel of the moving wheel 200 and realizing flexible steering of the vehicle.

[0045] The clutch control assembly 300 achieves clutch control through the cooperation of the rocker arm 310, drive cylinder 320, gear shaft 330, clutch gear 340 and control core rod 350.

[0046] When the drive cylinder 320 outputs thrust, it drives the rocker arm 310 to deflect, thereby pushing the control core rod 350 to move up and down inside the gear shaft 330. The end of the control core rod 350 is provided with a beveled part, which abuts against the abutment ball 331 during the lifting process, so that the abutment ball 331 slides radially along the through hole of the gear shaft 330. When the abutment ball 331 enters the meshing groove 341 inside the clutch tooth 340, the clutch tooth 340 and the gear shaft 330 are engaged, and the power can be transmitted from the drive motor 130 to the transmission shaft 120, driving the moving wheel 200 to rotate.

[0047] When the control core rod 350 moves in the reverse direction, the abutment ball 331 disengages from the groove 341, the clutch tooth 340 and the gear shaft 330 are disengaged, the power of the drive motor 130 is cut off, and the moving wheel 200 stops being driven by power, thus achieving the effect of idling or braking.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
