Description

Technical Field

[0001] This utility model relates to the field of electric scooters, and more particularly to a hand-push electric scooter with a detachable front bucket. Background Technology

[0002] Electric scooters are transportation devices based on traditional human-powered scooters, with the addition of an electric motor. Electric scooters are generally divided into two-wheel drive or single-wheel drive types, with the most common transmission methods being hub motors and belt drive. Their primary power source is a lithium battery pack, and electric scooters are typically two-wheeled, three-wheeled, or four-wheeled. To accommodate storage needs, some scooters now have a front-mounted storage basket.

[0003] The applicant previously applied for a multi-functional scooter with a front cargo box, with publication number CN222859663U. The front cargo box has auxiliary wheels and can be opened to put the cargo box in a four-wheel support state when the cargo box is disconnected. It is fixed and opened using locking pins. The process of opening and closing requires separate tools and is prone to shaking. It is also prone to noise when closed. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a detachable front bucket for both hand-push and electric use as a scooter.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method: A scooter with a detachable front bucket that can be used for both hand and electric use, including the scooter body and the front bucket; the front bucket includes the bucket body and the bottom frame, with fixed wheels at the front end of the lower side of the frame and movable wheel assemblies at the rear side of the frame. The movable wheel assembly includes a rotating arm and a wheel body connected to one end of the rotating arm. A first limiting post is provided on the frame, and a first latch is provided on the rotating arm. When the rotating arm is retracted, it is in a horizontal state, and the first latch is engaged with the first limiting post. It also includes a central shaft fixed on the frame, a rotating arm sleeved on the central shaft and able to rotate around the central shaft; a second bayonet is provided at the other end of the rotating arm, and a second limiting structure is also provided on the frame. When the rotating arm is in the open state, the second bayonet is engaged with the second limiting structure.

[0006] Preferably, the second limiting structure includes a limiting frame mounted on the frame. The limiting frame includes a left limiting plate and a right limiting plate, both of which are provided with a sliding groove. It also includes a first spring and a limiting rod. The limiting rod is inserted into the sliding groove and can slide along the sliding groove. One end of the first spring is fixed to the limiting frame, and the other end is fixed to the middle of the limiting rod. The other end of the rotating arm is provided with a second latch. When in the open state, the second latch is engaged with the limiting rod, and the first spring is in a stretched state.

[0007] Preferably, a torsion spring is fitted on the central shaft, a first limiting plate is provided on the rotating arm, and a second limiting plate is provided on the frame. One end of the torsion spring abuts against the first limiting plate, and the other end abuts against the second limiting plate. When the rotating arm is retracted, the torsion spring is in a compressed state.

[0008] Preferably, the rotating arm is inserted into the central shaft, and the rotating arm can move axially along the central shaft.

[0009] Preferably, it also includes a support spring sleeved on the central shaft, the other end of the central shaft has a limiting plate, the support spring is located on the outside of the rotating arm, one end of the support spring is supported on the rotating arm, and the other end is supported on the frame.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example

[0018] The scooter with a detachable front bucket is a push-pull electric scooter, including the scooter body 1 and the front bucket 2. The front bucket 2 includes the bucket body 3 and the bottom frame 4. The front end of the frame 4 is equipped with a fixed wheel 5, and the rear side of the frame 4 is equipped with a movable wheel assembly 6. The fixed wheel 5 is always in the state of supporting the bucket body 3, while the movable wheel assembly 6 can be opened or closed as needed.

[0019] When the cargo box 2 is attached to the scooter body 1, the movable wheel assembly 6 is retracted, making steering easier. When the cargo box 2 needs to be used alone or requires greater support, the movable wheel assembly 6 is retracted.

[0020] The movable wheel assembly 6 in this solution opens or retracts by rotating, and then is fixed in place by a limiting structure, thereby achieving the purpose of portable opening and reducing the number of parts used.

[0021] Specifically in this embodiment, the movable wheel assembly 6 includes a rotating arm 7 and a wheel body 8 connected to one end of the rotating arm 7. The rotating arm 7 is a rod structure, and a first limiting post 9 is provided on the frame 4. A first latch 10 is provided on the rotating arm 7. When the rotating arm 7 is retracted, it is in a horizontal state, and the first latch 10 is latched on the first limiting post 9.

[0022] To enable the rotation of the rotating arm 7, this design also includes a central shaft 11 fixed to the frame 4. The rotating arm 7 is fitted onto the central shaft 11 and can rotate around it. A second latch 12 is provided at the other end of the rotating arm 7, and a second limiting structure is also provided on the frame 4. When the rotating arm 7 is in the open state, the second latch 12 engages with the second limiting structure. The central shaft 11 serves as a support shaft, supporting the entire rotating arm 7. The arm is then locked in place by the latch structure in both the retracted and open states.

[0023] Specifically, in this embodiment, the second limiting structure includes a limiting frame 13 mounted on the frame 4. The limiting frame 13 includes a left limiting plate 14 and a right limiting plate 15, both of which are provided with sliding grooves 16. It also includes a first spring 17 and a limiting rod 19. The limiting rod 19 is inserted into the sliding groove 16 and can slide along it. One end of the first spring 17 is fixed to the limiting frame 13, and the other end is fixed to the middle of the limiting rod 19. The other end of the rotating arm 7 is provided with a second latch 12. In the open state, the second latch 12 engages with the limiting rod 19, putting the first spring 17 in a stretched state. This structural design ensures that the limiting rod 19 can slide under force within the sliding groove 16, thus allowing the rotating arm 7 to stably engage with the second latch 12 in the open state, while also providing a certain degree of force-bounce capability, thus acting as a buffer. To prevent the first spring 17 from being stretched and failing due to excessive force on the rotating arm 7, limit blocks that restrict the stroke are provided on the left limit plate 14 and the right limit plate 15.

[0024] Specifically, in this embodiment, the slide 16 is inclined, and its inclination is equal to the inclination of the rotating arm 7 when it is in the open state. Specifically, the slide 16 is inclined, and the inclination angle of the slide 16 is the same as the inclination angle of the rotating arm 7 when it is in the fully open state. The limiting rod 19 is located on the rotation path of the second bayonet 12.

[0025] In the initial state, part of the limiting rod 19 is located on the path of the outer wall of the second opening, and part is located on the inner side of the outer wall of the second opening. When the rotating arm 7 is opened, the outer wall of the second latch 12 presses down on the limiting rod 19, causing it to slide downwards. After the limiting rod 19 passes the edge of the outer wall of the second latch 12, it falls into the second latch 12, and the first spring 17 instantly returns to its original position and abuts against the inner wall of the second latch 12. When it needs to be opened, simply pull down the limiting rod 19 so that the entire limiting rod 19 is located outside the second latch 12 to achieve the engagement of the limiting rod 19 and the second latch 12, thus enabling the rotating arm 7 to be retracted.

[0026] Specifically, in this embodiment, the upper ends of the left limiting plate 14 and the right limiting plate 15 are connected by a connecting plate 26. A guide shaft 27 is also provided in the middle of the limiting rod 19, and the guide shaft 27 slides through the connecting plate 26. A first spring 17 is sleeved on the guide shaft 27. Both ends of the first spring 17 are connected to the connecting plate 26 and the limiting rod 19 via hooks.

[0027] In this embodiment, the rotating arm 7 is inserted into the central shaft 11, and the rotating arm 7 can move axially along the central shaft 11. A baffle 25 is provided at the outer end of the central shaft 11, and a support spring 24 is also sleeved on the central shaft 11. The support spring 24 is located outside the rotating arm 7, with one end supporting the rotating arm 7 and the other end supporting the baffle 25. This structural arrangement ensures that, in the initial state, the position of the rotating arm 7 can be tightly fitted to one end of the central shaft 11 under the action of the support spring 24 to prevent its axial movement.

[0028] In this embodiment, a torsion spring 21 is sleeved on the central shaft 11, a first limiting plate 22 is provided on the rotating arm 7, and a second limiting plate 23 is provided on the frame 4. One end of the torsion spring 21 abuts against the first limiting plate 22, and the other end abuts against the second limiting plate 23. When the rotating arm 7 is retracted, the torsion spring 21 is in a compressed state. Specifically, in this embodiment, both the first limiting plate 22 and the second limiting plate 23 are L-shaped plates, and the two ends of the torsion spring 21 are respectively limited by the first limiting plate 22 and the second limiting plate 23. When the rotating arm 7 is released, the torsion spring 21 releases torque to push the rotating arm 7 to rotate to the right. In this embodiment, the front truck bed 2 and the scooter body 1 are detachably connected.

[0029] When the rotating arm 7 is in the retracted state, the first latch 10 is engaged with the first limiting post 9. At this time, the torsion spring 21 is under stress and twisted. Since the position of the second limiting plate 23 on the right is fixed, the torsion spring 21 can only apply a rightward force to the rotating arm 7, so that the first latch 10 is more reliably engaged with the first limiting post 9.

[0030] When the rotating arm 7 needs to be lowered and opened, rotate the rotating arm 7 upward and pull it outward, further compressing the support spring 24. At this point, the first limiting post 9 is no longer on the rotation path of the first latch 10. Then, the torsion spring 21 releases torque to rotate the rotating arm 7 to the open state. When the second latch 12 abuts against the limiting rod 19, continue to lift it upward and pull the limiting rod 19 downward so that it falls into the second latch 12, completing the opening action. When retracting, pull the limiting rod 19 downward to disengage it from the position of the second latch 12, then retract the rotating arm 7. When rotating to the first limiting post 9, first pull the rotating arm 7 outward and upward so that the first latch 10 is above the first limiting post 9. At this point, release the rotating arm 7, and the first latch 10 is engaged with the first limiting post 9.
