Description

Technical Field

[0001] The utility model belongs to the technical field of storage boxes or vehicle baskets, and in particular relates to an electric turnover drive device and a basket cover or tail box cover turnover assembly for electric vehicles. Background Art

[0002] With the rapid development of the sharing economy, shared electric bikes are gaining popularity among the general public as a convenient and environmentally friendly means of transportation. However, while enjoying the convenience of shared electric bikes, riding safety, especially the wearing of helmets, has become an increasingly prominent issue that needs to be addressed.

[0003] Currently, some shared electric bikes on the market are equipped with helmets, which has improved riding safety to a certain extent. However, the storage and anti-theft issues of helmets have always been a problem that has troubled shared electric bike operators.

[0004] Existing helmets are generally placed in a basket with an open top, where the helmet is locked to the basket via an electronically controlled lock. For example, a prior patent application (publication number CN217260429U) proposes an electric vehicle basket assembly and a shared electric vehicle. The electronically controlled lock inside the basket cooperates with a locking pin on the helmet to achieve a tight connection between the helmet and the basket. This solution not only effectively prevents the loss of the helmet, but also uses internet technology to synchronize the shared electric vehicle with the helmet wearing status. This means that the user must put on the helmet before starting the bike; otherwise, the bike cannot be ridden. Furthermore, the helmet must be returned correctly when returning the bike; otherwise, the bike cannot be returned, greatly improving riding safety.

[0005] Problems with existing technologies:

[0006] Although the electronically controlled latch lock system solves the problem of helmet loss and reminders to wear helmets to a certain extent, it requires a high level of helmet modification and requires a special locking pin component to be installed on the helmet, which increases the manufacturing cost and complexity of the helmet and also limits the versatility of the helmet.

[0007] The open design allows dust, rainwater, and even garbage to accumulate inside the basket, seriously affecting its hygiene. Because the basket is open and often exposed to the elements, it is susceptible to erosion from wind, rain, sun, and other natural factors, which can accelerate aging, deformation, and even damage. This not only affects the appearance but can also reduce the basket's functionality.

[0008] Currently, baskets are hinged with lids, which are conventional techniques. In conventional techniques, basket lids or trunk lids are typically opened manually. If the basket lid or trunk lid has a locking function, it is often locked with a mechanical lock or self-locking latch between the basket lid or trunk lid and the basket. However, in the context of shared electric motorcycles, this design can be cumbersome for users. Therefore, the present utility model aims to design an electric flip drive device that can both automatically open and lock. Utility Model Content

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] See also Figures 1 to 3An electric flip drive device includes a housing 1-1, a motor 1-2 installed in the housing, an output gear 1-3 installed on the output shaft of the motor, the output gear meshing with a reduction gear pair 1-4, and the final gear of the reduction gear pair meshing with a power output gear 1-5; the secondary gear of the reduction gear pair in the housing meshes with a locking drive gear 1-11, and the purpose of meshing the secondary gear is to achieve unlocking before the power output gear drives the power output sleeve; the locking drive is installed on a locking drive shaft 1-12, and the end of the locking drive shaft is connected to a locking mechanism 1-13 through a gear 1-120, and the locking mechanism 1-13 reciprocates in a direction perpendicular to the support shaft, thereby achieving the function of locking or unlocking. The electric flip drive device is exquisitely designed. It not only has an excellent driving and flipping function, but also realizes the function of outputting locking power at the same time under the same power source through a clever mechanical structure design, truly achieving "one machine with two uses". This innovative design not only improves the overall efficiency of the equipment but also significantly saves energy and space, making the device a significant advantage in applications requiring simultaneous flipping and locking control. Its compact structure and efficient performance make this electric flip drive an ideal choice for many automated equipment, providing users with a more convenient and efficient experience.

[0036] Preferably, the locking mechanism 1-13 includes a locking block 1-130 installed in the sliding groove of the mounting shell, which enables the locking block to move in a specific direction under the constraint of the sliding groove; guide grooves 1-131 are provided at both ends of the cavity of the locking block and are perpendicular to the direction of the support axis, and a locking drive block 1-132 is slidably installed in the guide groove, ensuring that the locking drive block can maintain a stable direction and path when moving, and a tooth 1-1320 is provided below the locking drive block to cooperate with the locking drive gear, and the rotation of the locking drive gear can be converted into a linear movement of the locking drive block; a spring 1-133 is provided between the locking drive block and the locking block, and the elastic force of the spring can provide a pre-tightening force for the locking drive block to ensure its engagement with the locking drive gear. It fits tightly and can also provide a reset force when needed; a locking arm 1-134 is provided at the end of the locking block, and a shift fork 1-135 is provided on the outside of the locking arm, so that the locking mechanism can drive the movement of the locking arm and the shift fork through external force, thereby controlling the position of the locking block; in order to detect the position of the locking block, an in-position detection switch 1-136 is installed on the shell at the tail of the locking block. After the locking block is triggered, the lock is confirmed to be in place, and the in-position detection switch is electrically connected to the electric opening and closing device; a locking assembly 1-20 is installed on the inner side of the mounting frame corresponding to the position of the shift fork through an axis; the locking assembly 1-20 is used to lock the flip arm. When locked, the flip arm is at the lower flip end point. At this time, the flip arm cannot be opened manually, thereby playing an anti-theft function.

[0037] In summary, the locking mechanism mechanically achieves both actuation and locking functions, providing a stable locking mechanism. This stability is achieved through the ingenious design of the locking block, locking drive block, locking drive gear, and spring. When the flip arm needs to be locked, the locking drive gear rotates to drive the locking drive block, which in turn moves the locking block and locking arm, allowing the locking assembly to engage with the locking slot, achieving locking. The mechanism also offers a flexible unlocking function: when unlocking is required, simply reverse the locking drive gear, pushing the shift fork in the opposite direction, disengaging the locking assembly from the locking slot and unlocking the mechanism. This design makes unlocking the locking mechanism equally flexible and convenient. The locking mechanism is compact and reliable: The compact design of the entire locking mechanism and the tight fit between its components ensure its reliability and stability in practical applications. Furthermore, the use of sliding grooves, guide slots, and other structures to constrain the movement path and direction of the components also ensures smooth and accurate operation.

[0038] Preferably, a spring mounting groove 1-137 is provided in the locking drive block, in which a spring 1-138 is mounted, and the outer diameter of the spring is greater than the width of the guide groove. This technical feature ensures the stability of the spring in the locking mechanism through a clever design.

[0039] Application Example 1, please refer to Figures 1 to 5A basket cover or trunk cover flip assembly for an electric vehicle includes a flip mechanism 2, the flip mechanism includes a mounting frame 2-1, which is connected to the basket and a rotating arm 2-2 hingedly mounted on the mounting frame, the rotating arm including a buckling portion 2-20 and a rotating support portion 2-21; the lower surface of the buckling portion 2-20 is used to limit the helmet; the rotating support portion is mounted on a support shaft 2-3, which is mounted on the mounting frame, and a power output gear 1-5 is mounted on the support shaft, which engages with the final gear of the above-mentioned reduction gear pair; a clutch spring 1-6 is provided between the power output gear and the rotating support portion, and a clutch spring is provided between the power output gear and the rotating support portion. The clutch spring may provide a preload to ensure good meshing between the power output gear and the adjacent gear, or realize a clutch function in the event of an overload, thereby protecting the motor; the power output gear is coaxially provided with end face teeth 1-7, the end face teeth are connected to the power output end face gear 1-8, the power output end face gear is connected to the power output sleeve 1-80, the outer end of the power output sleeve is connected to the rotating support part 2-21, and drives the rotating support part to rotate around the support shaft, specifically, the end of the power output sleeve is provided with a square head 1-9, and the corresponding power output sleeve is provided on the rotating support part to cooperate with the square head. The square head and the square slot cooperate to realize power transmission. When the power output gear rotates, it drives the rotating support part to rotate around the support shaft through the end face teeth, the power output end face gear and the power output sleeve. The rotating support part of the support shaft or the rotating arm is connected to the electric flip drive device through a locking assembly. The electric flip drive device adopts the above-mentioned electric flip drive device. The driving component of the electric flip drive device is connected to the locking assembly, and the locking assembly is used to lock the rotating arm in the closed position.

[0040] In this embodiment, please refer to Figure 6 and Figure 7 The locking assembly 1-20 includes a locking body 1-21, a slot 1-23 cooperating with the shift fork is provided at the lower part of the locking body, a locking protrusion 1-22 is provided on the locking body 1-21 on the flip arm side, and a locking slot 2-22 is provided on the rotation support part of the flip arm. When the locking protrusion cooperates with the locking slot, the flip arm is located at the lower flip end point and the flip arm is locked. Figure 6 In the locked state, when the flip arm rises, the motor rotates to drive the secondary gear of the reduction gear pair in the shell to engage the locking drive gear 1-11 to move, and the gear 1-120 coaxially installed with the locking drive gear 1-11 drives the locking drive block in the locking block to move upward. During the movement, when the spring abuts against both sides of the guide groove 1-131, it drives the locking block to move upward in a straight line. The fork 1-135 on the locking arm will drive the locking body to rotate counterclockwise, thereby achieving unlocking. The flip arm will rise as the motor continues to rotate until it is fully opened. The locking process is opposite to the movement state of the components in the above-mentioned unlocking process.

[0041] Application Example 2, please refer to Figure 8 and Figure 9 The locking assembly includes a locking body 1-21, a driving plate 1-24 is provided at both ends of the locking body, an oblong limiting slide groove 1-25 is provided on the driving plate, and the shift fork 1-135 on the outside of the locking arm is inserted into the limiting slide groove below; a transverse shaft 1-250 is inserted into the upper limiting groove, and the transverse shaft is fixedly connected to the locking slider 1-26, and a slide groove 1-27 is provided on the inner side of the side wall of the mounting frame corresponding to the locking slider, and the locking slider is slidably installed in the slide groove; a locking sleeve 1-28 is installed on the support shaft on the side of the locking slider, and the locking sleeve is provided with a flip The rotating arm driving surface 1-29 and the locking surface 1-30 of the locking slider; a torsion spring 1-31 is installed in the locking sleeve, and the torsion spring is sleeved on the support shaft. One end of the torsion spring is inserted into the slot on the locking sleeve, and the other end is inserted into the rotation support part of the flip arm. After the flip arm is closed, the torsion spring can absorb part of the external force when it is turned and rotated, so that the flip arm is slightly raised at an angle. After the force is lost, it automatically recovers to ensure that the flip arm is fastened; the flip arm driving surface 1-29 is in contact with the abutting surface of the rotation support part of the flip arm; when the front end of the locking slider is matched with the locking surface of the locking slider, the flip arm is at the lower flip end point. Figure 8 In the unlocked state, when locking is required, the motor rotates to drive the secondary gear of the reduction gear pair in the housing to engage the locking drive gear 1-11 to move, and the gear 1-120 coaxially installed with the locking drive gear 1-11 drives the locking drive block in the locking block to move downward. During the movement, when the spring abuts against both sides of the guide groove 1-131, it drives the locking block to move downward in a straight line. The shift fork 1-135 on the locking arm will drive the locking body 1-22 to rotate clockwise, and the transverse shaft drives the locking slider 1-26 to move forward until it cooperates with the locking surface 1-30 of the locking slider to achieve locking; the unlocking process is opposite to the operating status of each component in the above-mentioned locking process.

[0042] This technical solution demonstrates an efficient and reliable locking mechanism, the core of which lies in its compact structural design and ingenious transmission mechanism. Precise control of the flip arm is achieved through the close combination of the drive plate, limit slide, shift fork, transverse shaft and locking slider. The oblong limit slide provides a flexible range of movement for the shift fork, ensuring the stability and accuracy of the locking mechanism during operation. At the same time, the use of a torsion spring in the locking sleeve provides a preload for the locking mechanism, which not only enables the locking slider to remain in a specific position, but also releases the stored energy during the unlocking process, achieving rapid and smooth unlocking. The significant effect of this technical solution lies in its compact structure, stable performance and flexible operation mode, which makes it have broad application prospects and market demand in various occasions where the flip arm locking function is required, and provides a strong guarantee for the stable operation of related equipment.

[0043] Example 3, in this example, please refer to Figure 10 The locking component 1-20 includes a locking body 1-21, a slot 1-23 cooperating with the shift fork is provided at the lower part of the locking body, a locking sleeve 1-28 is installed on the support shaft on the locking slider side, and a flip arm driving surface 1-29 and a locking slider locking surface 1-30 are provided on the locking sleeve; a torsion spring 1-31 is installed in the locking sleeve, and the torsion spring is sleeved on the support shaft, one end of the torsion spring is inserted in the slot on the locking sleeve, and the other end is inserted on the rotation support part of the flip arm. After the flip arm is closed, the torsion spring can absorb part of the external force when it is pulled and rotated, so that the flip arm is slightly raised by an angle. After the force is lost, it automatically recovers to ensure that the flip arm is fastened; the flip arm driving surface 1-29 is in contact with the abutting surface of the rotation support part of the flip arm; when the front end of the locking slider cooperates with the locking surface of the locking slider, the flip arm is located at the lower flip end point. A locking sleeve is installed on the support shaft on the locking slider side, and the locking sleeve is provided with a flip arm driving surface and a locking slider locking surface; a torsion spring is installed in the locking sleeve, and the torsion spring is sleeved on the support shaft. When the locking protrusion is locked with the locking surface of the locking slider, the flip arm is located at the lower flip end point and the flip arm is locked.

[0044] The aforementioned electric vehicle basket or trunk lid flip assembly is applied to the basket 3 or trunk of a shared electric vehicle and connected to the basket cover 4 or trunk lid (generally referring to the front basket or trunk lid) or trunk lid (generally the trunk lid of a rear trunk). The basket or trunk lid opens and closes as the flip mechanism rotates, thereby locking a shared helmet 5. The basket or trunk lid is fixedly connected to the flip arm of the flip mechanism via fasteners. After connection, a cover plate or rain cap shields the connection (not shown) to enable the basket to open and close. The cover fully cooperates with the basket, providing excellent dust and rain protection, enhancing the practicality and safety of the basket or trunk lid, and protecting the shared helmet.
