Detailed Implementation

[0019] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0020] like Figures 1 to 4 As shown, an electric suitcase 100 includes: a suitcase body 10, a control drive device 20, and a connecting assembly 30.

[0021] The box 10 forms a storage space. The box 10 is equipped with support wheels. The support wheels are located at the bottom of the box 10 to support the box 10.

[0022] The control drive device 20 enables the self-driving of the housing 10 and controls its direction of travel. The connecting component 30 connects the housing 10 and the control drive device 20. The control drive device 20 drives the housing 10 to move through the connecting component 30.

[0023] like Figure 1 , Figure 3 , Figures 5 to 7 As shown, the control drive device 20 includes: wheel frame 21, drive wheel 22, motor 23, steering handle 24, connecting seat 25, and handlebar assembly 26.

[0024] The active drive wheel 22 is rotatably mounted to the wheel frame 21. The motor 23 drives the active drive wheel 22 to rotate, thereby enabling the housing 10 to move self-propelled.

[0025] The motor can directly drive the drive wheel to rotate, or it can indirectly drive the drive wheel to rotate through a transmission mechanism such as a gearbox. The motor can be a hub motor or a hub motor. As a specific implementation, motor 23 is a hub motor 23. Motor 23 is mounted on the drive wheel 22.

[0026] like Figure 1 , Figure 3 , Figures 5 to 7 As shown, the steering handle 24 is for the user to grip. The connecting seat 25 is used to connect the connecting assembly 30. The connecting assembly 30 connects the connecting seat 25 and the housing 10. The handlebar assembly 26 connects the steering handle 24 and the wheel carrier 21. The connection can be direct or indirect. The steering handle 24 is mounted to the handlebar assembly 26. The wheel carrier 21 is mounted to the handlebar assembly 26. Specifically, the steering handle 24 is mounted to the top of the handlebar assembly 26. The wheel carrier 21 is mounted to the bottom of the handlebar assembly 26. The handlebar assembly 26 and the wheel carrier 21 are rotatably mounted to the connecting seat 25 as a whole; this can also be understood as the rotatable mounting relationship between the handlebar assembly 26 and the wheel carrier 21 when the handlebar assembly 26 and the wheel carrier 21 are considered as a single unit.

[0027] As an optional implementation, rotation is transmitted between the handlebar assembly and the wheel frame via a transmission mechanism. For example, a gear transmission mechanism is provided between the handlebar assembly and the wheel frame, using the rotation of the handlebar assembly relative to the connecting seat to drive the rotation of the wheel frame relative to the connecting seat.

[0028] As a specific implementation method, such as Figure 7 As shown, the handlebar assembly 26 is fixedly connected to the wheel carrier 21. The handlebar assembly 26 is fixedly connected to the steering handle 24.

[0029] like Figure 1 , Figure 3 , Figures 5 to 7 As shown, the steering handle 24 serves to control the direction of travel. Specifically, when the user turns the steering handle 24, the handlebar assembly 26 drives the wheel carrier 21 to rotate to control the direction of travel. The steering force applied by the user to the steering handle 24 is transmitted to the wheel carrier 21 through the handlebar assembly 26, and the rotation of the wheel carrier 21 changes the direction of travel of the drive wheel 22.

[0030] The handlebar assembly comprises several handlebar sections. These sections are interconnected to form the handlebar assembly. The connections between the handlebar sections can be either movable or fixed. Movable connections allow for a smaller size and easier storage of the handlebar assembly. For example, the handlebar assembly can be configured with a sliding connection to form a telescopic handlebar assembly; or it can be configured with a rotating connection to form a folding handlebar assembly. A locking mechanism can be included to secure the movable handlebar sections. The top handlebar connects to the steering handle. The bottom handlebar connects to the wheel hub. Specifically, the handlebar sections constitute a telescopic handlebar assembly.

[0031] As an optional implementation, the handle assembly may consist of only one handle.

[0032] In one specific embodiment, the handlebar assembly 26 includes an upper handlebar and a lower handlebar. A steering handle 24 is mounted to the upper handlebar. A wheel bracket 21 is mounted to the lower handlebar. The upper and lower handlebars slide relative to each other, forming a telescopic rod assembly. The top of the upper handlebar is connected to the steering handle 24. The bottom of the lower handlebar is connected to the wheel bracket 21. After the telescopic rod assembly formed by the upper and lower handlebars extends, the upper and lower handlebars can be locked, allowing them to rotate synchronously as a single unit. The locking mechanism between the upper and lower handlebars is a conventional technical means that those skilled in the art would conceive of, and is not the core of this invention; therefore, its specific structure is not described in detail in the specification.

[0033] like Figures 1 to 4 As shown, in one specific embodiment, the support wheels include a front support wheel 111 and a rear support wheel 112. The support wheel located at the front in the direction of travel of the electric luggage compartment 100 is the front support wheel 111, and the support wheel located at the rear is the rear support wheel 112.

[0034] In one specific implementation, there are two front support wheels 111 and two rear support wheels 112. The two front support wheels 111 and the two rear support wheels 112 are respectively positioned at the four corners of the bottom of the housing 10. The rotation axes of the two front support wheels 111 are coaxial. The rotation axes of the two rear support wheels 112 are coaxial.

[0035] As an optional implementation, the number of front and rear support wheels is not limited to two. For example, there can be one front support wheel and two rear support wheels. Alternatively, there can be two front support wheels and one rear support wheel, or both front and rear support wheels can be one. Stable support can be achieved with three support wheels, and stable support can also be achieved by widening the width of the support wheels when using two support wheels. As another optional implementation, the number of front and rear support wheels can be multiple.

[0036] As an optional implementation, the front support wheel may be omitted, in which case the rear support wheel and the drive wheel jointly support the housing.

[0037] The front and rear support wheels can be constructed as the same type of wheel or as different types of wheels. The support wheels can be either omnidirectional wheels or directional wheels. Specifically, for example... Figures 1 to 4 As shown, the bottom of the housing 10 is provided with a front support wheel 111 and a rear support wheel 112. The front support wheel 111 is a swivel wheel. The rear support wheel 112 is a fixed wheel. The diameter of the rear support wheel 112 is larger than the diameter of the front support wheel 111. Specifically, the diameter of the rear support wheel 112 is approximately equal to that of the drive wheel 22.

[0038] As a preferred embodiment, the electric luggage case 100 is equipped with an electric riding mode (see reference). Figure 1 and Figure 3 ) and manual dragging status (see reference) Figure 2 and Figure 4 ).

[0039] like Figure 4 As shown, in manual towing mode, the active drive wheel 22 is out of contact with the ground, and the front support wheel 111 and the rear support wheel 112 are in contact with the ground to support the box 10.

[0040] like Figure 3 As shown, in electric riding mode, the drive wheel 22 and the rear support wheel 112 contact the ground and support the housing 10, while the front support wheel 111 is detached from the ground and positioned between the drive wheel 22 and the rear support wheel 112. In electric riding mode, the user can sit on the housing 10 and control the direction of travel using the handlebars 24. Specifically, the user sits on the top of the housing 10. The top of the housing 10 is equipped with a seat cushion for user comfort.

[0041] Automatic luggage can be both electric-powered and easily towed manually.

[0042] like Figure 3 As shown, in electric riding mode, the front support wheel 111 is lifted off the ground, forming a support structure with the active drive wheel 22 and the rear support wheel 112, improving handling. Figure 2 As shown, the control drive device 20 can be retracted, reducing storage volume and facilitating manual towing. In manual towing mode, it is supported by the front support wheel 111 and the rear support wheel 112, making the box 10 more stable and towing more flexible. Manual towing is more effortless when the active drive wheel 22 is off the ground compared to when the active drive wheel 22 is in contact with the ground.

[0043] In one specific implementation, the suitcase 10 is equipped with a manual pull rod. The manual pull rod has a handle for the user to grip. In manual towing mode, the user can pull the electric suitcase 100 forward using the manual pull rod. At this time, the front support wheels 111 and the rear support wheels 112 support the suitcase 10. The control drive device 20 is lifted and stored on the suitcase 10. Specifically, the manual pull rod is located at the end of the suitcase 10 furthest from the control drive device 20.

[0044] As an alternative implementation, the container may not be equipped with a manual pull rod. In manual towing mode, the user can use the steering handle to pull the container forward, or push the container forward directly without using the steering handle.

[0045] In one specific implementation, the housing 10 has a storage space for accommodating the control drive device 20. In manual towing mode, the control drive device 20 is housed within the storage space.

[0046] In one specific implementation, the front support wheel 111 is a swivel wheel. The rear support wheel 112 is a fixed wheel. The fixed wheel on the rear support wheel 112 improves the stability of the box 10 during straight-line movement. The swivel wheel on the front support wheel 111 facilitates the turning of the box 10.

[0047] As an optional implementation, both the front support wheel and the rear support wheel are swivel wheels.

[0048] The rotatable connection between the wheel frame 21 and the connecting seat 25 also enables the active drive wheel 22 to function as a swivel wheel. In electric riding mode, rotating the wheel frame 21 changes the direction of travel of the active drive wheel 22. Specifically, there is one active drive wheel 22. The active drive wheel 22 and the two rear support wheels 112 form a three-point support. The rear support wheels 112 are directional wheels, improving the stability of the electric luggage compartment 100 during straight-line travel. The active drive wheel 22 can be steered to control the direction of travel of the electric luggage compartment 100.

[0049] As an optional implementation, the number of active drive wheels can also be set to two. The two active drive wheels rotate synchronously relative to the connecting seat. The two active drive wheels are arranged coaxially.

[0050] As a specific implementation method, such as Figure 1 and Figure 3 As shown, the connecting assembly 30 connects the housing 10 and the control drive device 20. The connecting assembly 30 transmits the traction force of the control drive device 20 to the housing 10, thereby causing the control drive device 20 to move the housing 10. Specifically, the connecting assembly 30 connects the housing 10 and the connecting seat 25.

[0051] The connection between the connecting components and the housing, as well as the connection between the connecting components and the control drive device, can be either a fixed connection or a movable connection. The connecting component can be fixed at one end and movable at the other. Alternatively, both ends can be movable. A movable connection refers to a connection with relative movement, such as a hinge or sliding connection. Movable connections allow for adjustable positions between the control drive device and the housing, enabling switching between manual towing and electric riding modes.

[0052] As a specific implementation method, such as Figures 1 to 4 As shown, the two ends of the connecting component 30 are movably connected to the connecting base 25 and the housing 10, respectively. The connecting component 30 has a retracted state and an unfolded state. When the connecting component 30 is in the retracted state, the control drive device 20 is retracted into the housing 10, and the electric luggage 100 is in a manually dragged state. When the connecting component 30 is in the unfolded state, the control drive device 20 is removed from the housing 10, and the electric luggage 100 is in an electric riding state. The position of the control drive device 20 can be adjusted by unfolding and retracting the connecting component 30.

[0053] More specifically, the two ends of the connecting component 30 are hinged to the connecting seat 25 and the housing 10, respectively.

[0054] like Figure 1 , Figure 3 , Figures 8 to 10 As shown, in one specific embodiment, the housing 10 is provided with a mounting base 12. The connecting assembly 30 is at least partially constructed as a rigid structure that is integrally rigid. This makes the structure more reliable. The two ends of the rigid structure of the connecting assembly 30 are respectively hinged to the connecting base 25 and the mounting base 12.

[0055] like Figure 1 , Figure 3 , Figure 8 , Figure 11 and Figure 12 As shown, in a preferred embodiment, the electric luggage case 100 also includes a locking device 40. The locking device 40 is used to lock the position of the connecting assembly 30. For example, when there is a movable connection at the end of the connecting assembly 30, the locking device 40 can be provided to achieve locking.

[0056] The locking device is used to lock the connecting component in a retracted state and / or an extended state. The locking device can be configured to lock the connecting component in the retracted state. Alternatively, the locking device can be configured to lock the connecting component in the extended state. Alternatively, the locking device can be used to lock both the retracted and extended states of the connecting component. The retracted and extended states can be locked using multiple locking devices or a single locking device.

[0057] A locking element is movably installed into one of the housing and the connecting assembly. The other of the housing and the connecting assembly has a locking slot. The locking element is inserted into the locking slot to lock the connecting assembly. The connecting assembly is unlocked when the locking element disengages from the locking slot.

[0058] As an optional implementation, the locking element is movably installed to the connecting assembly, and the housing is provided with a locking slot.

[0059] like Figure 1 , Figure 3 , Figure 8 , Figure 11 and Figure 12 As shown, in one specific embodiment, the locking member 41 is movably installed to the housing 10. The connecting assembly 30 has a locking slot. Specifically, the housing 10 has a mounting base 12. The connecting assembly 30 includes a main connecting member 31 and an auxiliary connecting member 32. Both ends of the main connecting member 31 are hinged to the connecting base 25 and the mounting base 12, respectively. Both ends of the auxiliary connecting member 32 are hinged to the connecting base 25 and the mounting base 12, respectively. Specifically, the main connecting member 31 is a rigid structure with overall rigidity. Similarly, the auxiliary connecting member 32 is also a rigid structure with overall rigidity.

[0060] The main connector 31, the auxiliary connector 32 and their mounting structure constitute a four-bar linkage, which can keep the handle bar assembly 26 parallel between the retracted state and the extended state, that is, maintain the posture of the handle bar assembly 26.

[0061] The locking element is movably installed into one of the mounting base and the main connector. The other of the mounting base and the main connector has a locking slot. The locking element is inserted into the locking slot to lock the position of the main connector relative to the mounting base. The locking element is unlocked when it disengages from the locking slot.

[0062] As an optional implementation, the locking member is movably installed to the main connector, and the mounting base is provided with a locking slot hole.

[0063] In one specific implementation, the locking member 41 is movably mounted to the mounting base 12. The main connector 31 is provided with a locking groove hole.

[0064] In one specific implementation, the auxiliary connector 32 does not intersect with the main connector 31. The auxiliary connector 32 and the main connector 31 do not constitute a scissor mechanism. Specifically, during the rotation of the main connector 31 relative to the connecting seat 25, the main connector 31 and the auxiliary connector 32 are parallel to each other.

[0065] The main connector 31 and auxiliary connector 32 of the connecting component 30 are configured such that it is not necessary to set two locking devices 40 to lock the two ends of the main connector 31 respectively. Only one end of the main connector 31 needs to be locked to achieve the position locking of the connecting component 30 relative to the housing 10 and the control drive device 20.

[0066] As an optional implementation, the connecting assembly may consist of only a main connector, without auxiliary connectors. The connecting assembly consists of a single, rigid structure. A locking mechanism is used to lock the main connector in place.

[0067] like Figures 8 to 12 In one specific implementation, the locking device 40 also includes a reset spring 42 and a pull rope 43.

[0068] The return spring 42 applies a force to the locking member 41, causing it to move into the lock slot. A pull cord 43 is connected to the locking member 41. The pull cord 43 can be pulled by the user to overcome the elastic force of the return spring 42. Pulling the pull cord 43 overcomes the elastic force of the return spring 42, causing the locking member 41 to move from inside the lock slot to outside, thus unlocking. The return spring 42 drives the locking member 41 from outside the lock slot into the lock slot, thus locking.

[0069] The structure of the pull cord 43 and the reset spring 42 makes it convenient for users to pull to unlock, and can achieve automatic reset and locking. In the locked state, the reset spring 42 can prevent accidental unlocking.

[0070] In one specific implementation, the locking device 40 further includes a release member 44. The release member 44 is connected to the pull cord 43. The release member 44 can be moved by the user to pull the pull cord 43. For example, the release member 44 can be configured as a handle, lever, or knob to pull the pull cord 43. The release member 44 allows the user to avoid direct contact with the thin pull cord 43, making the operation of pulling the pull cord 43 more comfortable.

[0071] In one specific implementation, the release element 44 is rotatably mounted to the housing 10. Specifically, the release element 44 is located on the top of the housing 10. The release element 44 has a contact portion 441 for the user to contact and rotate. The distance from the contact portion 441 to the axis of rotation of the release element 44 is greater than the distance from the position of the pull rope 43 connecting the release element 44 to the axis of rotation of the release element 44. The user can rotate the release element 44 by tilting the contact portion 441 upwards, which is convenient to operate. The connection method of the release element 44 forms a force-saving lever structure, which is easy to use.

[0072] As an optional implementation, the locking device can also be configured to unlock in other non-pull-cord unlocking methods, such as unlocking by pulling out the locking element or unlocking by sliding it out.

[0073] In one specific implementation, the mounting base 12 is provided with a pull rope limiting hole. The pull rope limiting hole limits the pull rope 43 to prevent the pull rope 43 from shaking on the housing 10. The pull rope 43 passes through the pull rope limiting hole.

[0074] In one specific embodiment, the locking device 40 further includes a lock frame 45. The lock frame 45 is movably mounted to the mounting base 12. The lock frame 45 is fitted with a locking element 41. Alternatively, the lock frame may have the locking element formed therein; that is, the locking element is part of the lock frame.

[0075] The return spring 42 directly resets the lock frame 45, thereby causing the locking member 41 to move into the lock slot and achieve reset. The pull rope 43 is connected to the locking member 41 through the lock frame 45. Specifically, the lock frame 45 is rotatably mounted to the mounting base 12. The pull rope 43 is connected to one end of the lock frame 45 away from the axis of rotation of the lock frame 45 relative to the mounting base 12. The return spring 42 is a torsion spring, and it is mounted on the axis of rotation of the lock frame 45 relative to the mounting base 12. Both ends of the return spring 42 abut against the lock frame 45 and the mounting base.

[0076] The connecting component 30 has a retracted state and an extended state. In the retracted state, the control drive device 20 is retracted close to the housing 10. In the extended state, the control drive device 20 is moved away from the housing 10, and the electric luggage case 100 is in an electric riding state. As a preferred embodiment, the locking device 40 can be used to lock the connecting component 30 in both the retracted and extended states. Specifically, the locking slot includes a first locking slot 311 and a second locking slot 312. When the locking member 41 is inserted into the first locking slot 311, the connecting component 30 is locked in the retracted state. When the locking member 41 is inserted into the second locking slot 312, the main connecting component 31 is locked in the extended state. More specifically, when the locking member 41 is inserted into the first locking slot 311, the main connecting component 31 is locked to keep the connecting component 30 in the retracted state. When the locking member 41 is inserted into the second locking slot 312, the main connecting component 31 is locked to keep the connecting component 30 in the extended state.

[0077] One of the mounting base 12 and the main connector 31 is provided with a first abutting structure. The other of the mounting base 12 and the main connector 31 is provided with a second abutting structure and a third abutting structure.

[0078] When the first abutting structure and the second abutting structure abut together, the first locking slot 311 aligns with the locking member 41. When the first abutting structure and the third abutting structure abut together, the second locking slot 312 aligns with the locking member 41. Specifically, one of the mounting base 12 and the main connecting member 31 is provided with an abutment block 3101. The other of the mounting base 12 and the main connecting member 31 is provided with an abutment block groove 1202. The abutment block 3101 slides in the abutment block groove 1202. The abutment block 3101 serves as the first abutting structure. The groove walls at both ends of the abutment block groove 1202 respectively constitute the second abutting structure and the third abutting structure.

[0079] As an optional implementation, the mounting base is provided with a first abutment structure. The main connector is provided with a second abutment structure and a third abutment structure.

[0080] In one specific implementation, the main connector 31 is provided with a first abutting structure. The mounting base 12 is provided with a second abutting structure and a third abutting structure. Specifically, the main connector 31 is provided with an abutting block 3101. The mounting base 12 is provided with an abutting block groove 1202. The structure is simple and has high reliability.

[0081] In a preferred embodiment, there are two main connectors 31. The two main connectors 31 are symmetrically arranged on both sides of the handlebar assembly 26. There are also two auxiliary connectors 32. The two auxiliary connectors 32 are symmetrically arranged on both sides of the handlebar assembly 26. A connecting seat 25 is fitted onto the outer periphery of the handlebar assembly 26. The two main connectors 31 are symmetrically arranged on both sides of the connecting seat 25. The two auxiliary connectors 32 are symmetrically arranged on both sides of the connecting seat 25. The main connectors 31 are located above the auxiliary connectors 32. Both the main connectors 31 and the auxiliary connectors 32 are sheet metal structures. The width of the main connector 31 is greater than the width of the auxiliary connector 32.

[0082] As a preferred implementation method, such as Figures 8 to 12 As shown, the mounting base 12 includes a connecting plate 121 and two side plates 122. The connecting plate 121 and the two side plates 122 are integrally formed. The two side plates 122 are respectively connected to both sides of the connecting plate 121. The connecting assembly 30 is located in the area enclosed by the connecting plate 121 and the two side plates 122. Two main connecting members 31 and two auxiliary connecting members 32 are rotatably connected to the two side plates 122. More specifically, the mounting base 12 also includes a base plate 123. The base plate 123, the connecting plate 121, and the two side plates 122 are integrally formed. The base plate 123 is connected to the bottom of the connecting plate 121. The rear support wheel 112 is rotatably mounted to the base plate 123. The side plates 122 form a stop groove 1202. The side plates 122 also form a locking groove 1221 for guiding the sliding of the locking member 41. After the locking member 41 slides to one side, it slides out from the first locking slot hole 311. After the main connecting member 31 rotates, it moves to the position where the second locking slot 312 aligns with the locking member 41. The locking member 41 slides in opposite directions in the locking groove 1221, and then enters the second locking slot 312 to achieve locking. Specifically, the first locking slots 311 on the two main connecting plates 121 are aligned with each other, and the second locking slots 312 are also aligned with each other. The locking member 41 simultaneously enters the first locking slots 311 of the two main connecting plates 121 to achieve locking. When the locking member 41 enters the second locking slot 312, it simultaneously enters the second locking slots 312 of the two main connecting plates 121 to achieve locking.

[0083] As a preferred implementation method, such as Figures 5 to 7As shown, the control drive unit 20 also includes a foot pedal 27. The foot pedal 27 is mounted to the connector 25. The foot pedal 27 is used to support the user's feet. In electric riding mode, the user can place their feet on the foot pedal 27.

[0084] As an optional implementation, a foot pedal may not be provided.

[0085] As a specific method, such as Figures 1 to 3 As shown, the electric luggage compartment 100 also includes a battery 28. The battery 28 supplies power to the motor 23. As a preferred embodiment, Figures 5 to 7 As shown, battery 28 is mounted on control drive device 20. Alternatively, control drive device 20 includes battery 28. Battery 28 supplies power to motor 23.

[0086] The control drive unit 20 has a storage state (reference) Figure 2 ) and usage status (reference) Figure 1 The storage state is the state when the control drive device 20 is not in use, in which case the control drive device 20 is stored away. In the use state, the control drive device 20 is used by the user to realize the self-driven movement of the housing 10.

[0087] The housing 10 has a receiving groove 102 for accommodating the control drive device 20.

[0088] When in use, the control drive 20 is disengaged from the receiving slot 102, and the battery 28 is located outside the receiving slot 102.

[0089] In the storage state, the control drive 20 is placed in the receiving slot 102, and the battery 28 is at least partially located in the receiving slot 102.

[0090] Specifically, when the control drive device 20 is in use, the electric luggage box 100 is in electric riding mode. When the control drive device 20 is in storage mode, the electric luggage box 100 is in manual towing mode.

[0091] When the operating drive is used, i.e., when the electric luggage case 100 is moving electrically, the battery 28 is away from the case body 10 and is in a relatively open space, which allows for better heat dissipation. In the storage state, the battery 28 is at least partially located in the receiving slot 102, reducing the exposed portion, and the case body 10 provides protection for the battery 28.

[0092] like Figures 1 to 4As shown, the housing 10 has a front end face 101. The front end face 101 is recessed inward to form a receiving groove 102. The receiving groove 102 is used to receive the control drive device 20. In the storage state, the battery 28 does not protrude from the front end face 101. The front end face 101 is the end face of the housing 10 facing the control drive device 20. Because the battery 28 does not protrude from the housing 10, the housing 10 can provide good protection for the battery 28.

[0093] In manual towing mode, the steering handlebar 24 and pedal 27 are located on the front side of the front end face 101, the handlebar assembly 26 is located on the rear side of the front end face 101, and the battery 28 is located in the receiving slot 102. In electric riding mode, the battery 28 and handlebar assembly 26 are located outside the receiving slot 102. In storage mode, the steering handlebar 24 and pedal 27 are located on the front side of the front end face 101, and the handlebar assembly 26 is located on the rear side of the front end face 101. In use mode, the handlebar assembly 26 is located on the front side of the front end face 101. In storage mode, the steering handlebar 24 and pedal can protect the battery 28, preventing the battery 28 from contacting the ground if the case 10 is tipped over. In addition, the steering handlebar 24 and pedal are located on the outside of the case 10, reducing the space occupied by the case 10 and allowing the case 10 to have a larger storage space.

[0094] As a specific implementation method, such as Figure 1 , Figures 5 to 7 , Figures 13 to 16 As shown, the control drive device 20 also includes a control circuit board 291 and a control housing 292. The control circuit board 291 is electrically connected to the motor 23. The control circuit board 291 is located inside the control housing 292.

[0095] In use, the control housing 292 is located outside the receiving slot 102. In storage, the control housing 292 does not protrude from the front end face 101. The battery 28 is located above the control housing 292. The battery 28 and the control housing 292 are disposed adjacent to each other.

[0096] In storage mode, enclosure 10 provides some protection for control box 292. Specifically, the battery 28 at least partially surrounds the handlebar assembly 26 in the circumferential direction. The battery 28 is disposed around the handlebar assembly 26 in the circumferential direction.

[0097] The battery can completely or partially surround the handlebar assembly. A complete surround means the battery is constructed as a closed loop. A partial surround means the battery is constructed as a loose loop.

[0098] More specifically, such as Figures 13 to 18As shown, the battery 28 includes a battery housing 281 and a plurality of battery cells 282. The battery cells 282 are located within the battery housing 281. The battery housing 281 is provided with a recess 2811. The handle assembly 26 is inserted into the recess 2811. A charging interface is provided on the battery housing 281. Specifically, the charging interface is located on the top of the battery housing 281. A power indicator light is also provided on the battery housing 281. Specifically, the power indicator light is located on the top of the battery housing 281.

[0099] like Figure 6 , Figure 7 , Figure 12 , Figure 17 As shown, the connector 25 is fitted around the outer periphery of the handlebar assembly 26. The battery 28 at least partially surrounds the connector 25 in the circumferential direction. The connector 25 is embedded in the slot 2811. In this arrangement, the slot 2811 is a notch-shaped slot on the side, where the battery 28 partially surrounds the handlebar assembly 26 in the circumferential direction. Alternatively, in this embodiment, the battery completely surrounds the handlebar assembly in the circumferential direction, in which case the slot is a through-hole shape.

[0100] The arrangement of the batteries 28 provides a larger contact surface with the outside, thereby improving heat dissipation performance.

[0101] like Figure 17 and Figure 18 As shown, the battery casing 281 forms a U-shaped structure. Multiple battery cells 282 are arranged in a U-shape. The handle assembly 26 is embedded within the space enclosed by the U-shaped structure. The U-shaped structure opens rearward toward the housing 10.

[0102] Specifically, the U-shaped structure forms the slot 2811. The slot 2811 opens rearward toward the housing 10.

[0103] In one specific implementation, the control drive device 20 further includes a control circuit board 291 and a control housing 292. The control circuit board 291 is electrically connected to the motor 23. The control circuit board 291 is located within the control housing 292. The battery 28 is slidably mounted to the control housing 292 along the open direction of the slot 2811. The control housing 292 is mounted to the connector 25. The control housing 292 supports the battery 28 from below. The control circuit board 291 is electrically connected to the motor 23 for controlling the motor 23.

[0104] The control drive unit 20 includes a battery holder. A battery 28 is removably installed to the battery holder. Specifically, the battery 28 is removably installed to the control housing 292, meaning the control housing 292 serves as the battery holder, and the control circuit board 291 is located inside the battery holder. More specifically, the battery 28 is removably installed to the top of the control housing 292; the top of the control housing 292 can also be understood as serving as the battery holder. The structural design of the battery 28 also facilitates removal and replacement.

[0105] like Figure 17 and Figure 18 As shown, the battery 28 includes a battery casing 281 and a plurality of battery cells 282. The battery cells 282 are located inside the battery casing 281.

[0106] A battery locking element is movably mounted on one of the battery holder and the battery housing. The other of the battery holder and the battery housing has a locking groove. The battery housing is slidably mounted to the battery holder.

[0107] As an optional implementation, the battery housing is provided with a locking groove. The battery holder is equipped with a locking element.

[0108] In one specific implementation, the battery housing 281 is equipped with a battery locking element 283. The battery holder is provided with a locking groove 293.

[0109] The battery locking element 283 can be operated by the user to move between the locked position and the unlocked position.

[0110] Battery locking element 283 is in the locked position (reference) Figure 15 When the battery is in use, the battery locking member 283 is inserted into the locking groove 293 to prevent the battery housing 281 from sliding relative to the battery holder and thus lock the battery 28.

[0111] When the battery locking member 283 is in the unlocked position, the battery locking member 283 is pulled out from the lock groove 293, and the battery housing 281 can slide relative to the battery holder to unlock the battery 28 and realize the removal of the battery 28.

[0112] Users can unlock and lock the battery 28 using the battery lock 283, making it convenient to remove and replace the battery 28.

[0113] In one specific implementation, the battery 28 is located above the battery holder. A locking groove 293 is formed on the battery holder. The battery locking member 283 is installed to the bottom of the battery housing 281. Gravity exerts a force on the battery locking member 283 to insert into the locking groove 293.

[0114] As a specific implementation method, such as Figure 16 As shown, the battery locking member 283 is also connected to a battery reset spring 284. The battery reset spring 284 applies a force to the battery locking member 283 to move it from the unlocked position to the locked position. The battery reset spring 284 also applies a force to the battery locking member 283 to insert it into the lock groove 293.

[0115] As a preferred method, the battery locking element 283 is installed at the bottom of the battery housing 281. The battery reset spring 284 and gravity together push the battery locking element 283 from the unlocked position to the locked position.

[0116] Specifically, the fastener 285 passes through the battery locking member 283 and is then fixed to the battery housing 281. The battery reset spring 284 is sleeved on the fastener 285. The two ends of the battery reset spring 284 abut against the head of the fastener 285 and the battery locking member 283, respectively.

[0117] As a specific implementation method, such as Figure 15 As shown, the battery locking member 283 is provided with an unlocking operation part 2831. When the user contacts the unlocking operation part 2831, it applies a force to the battery locking member 283 to move it from the locked position to the unlocked position. When the user pushes the unlocking operation part 2831 upward, the battery locking member 283 moves upward, thereby being pulled out of the lock groove 293, completing the unlocking.

[0118] In one specific implementation, a battery locking member 283 is disposed at the front end of the battery housing 281. The battery housing 281 is inserted into the battery holder along the open direction of the U-shaped structure.

[0119] When the battery housing 281 is mounted on the battery holder, in the insertion direction of the battery housing 281, the upstream height of the battery housing 281 is higher than the downstream height of the battery housing 281 (reference). Figure 3 (The height on the left is higher than the height on the right).

[0120] The battery 28 is provided with a first electrical connection terminal. The battery holder is provided with a second electrical connection terminal. When the battery 28 is installed on the battery holder, the first electrical connection terminal and the second electrical connection terminal are electrically connected. The basic principles, main features and advantages of this application have been shown and described above. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
