Description

Technical Field

[0001] This application relates to the field of bicycle technology, specifically to a locking and unlocking device and an electric bicycle. Background Technology

[0002] Electric-assisted bicycles (E-Bikes) are bicycles with electric auxiliary power, but are still primarily driven by human pedaling. They differ from electric bicycles that rely solely on electricity, and also from purely human-powered bicycles. During riding, the electric-assisted bicycle only provides additional auxiliary power through the motor drive system when the rider actively pedals, thereby reducing the pedaling effort and making riding easier and less strenuous. An electric-assisted bicycle includes a frame, motor, battery, and control system. The frame houses the wheels and pedals, the battery provides driving force to the motor, and the control system controls the motor to assist in driving the pedals based on the rider's riding status or operating commands, further reducing pedaling effort.

[0003] In related technologies, to facilitate battery assembly onto the frame, a mounting cavity for accommodating the battery is typically provided inside the downtube of the frame. The mounting cavity has an opening, through which the battery is inserted into the mounting cavity. A battery lock within the mounting cavity secures the battery in place. Then, a cover plate is used to close the opening of the mounting cavity, and finally, a cover plate lock is used to secure the cover plate to the downtube. This ensures the stability of the electrical connection between the battery and other components, guarantees a stable power supply, improves the aesthetics of the electric bicycle, and prevents the battery from being exposed, thus extending the battery's lifespan.

[0004] Since the battery lock and cover lock are installed independently, two sets of installation structures are required, which not only increases material and assembly costs, but also requires more installation space on the lower tube, which is not conducive to the lightweight design of the whole vehicle and reduces the aesthetics of the whole vehicle.

[0005] This section provides background information related to this application, which is not necessarily prior art. Summary of the Invention

[0006] One object of this application is to solve or at least alleviate some or all of the aforementioned problems. Therefore, one object of this application is to provide a locking / unlocking device and an electric bicycle.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] On one hand, this application provides a locking and unlocking device for locking a battery and a cover plate to a mounting member, wherein the mounting member has an open mounting cavity, and the locking and unlocking device includes:

[0009] The cover plate lock bracket is located inside the mounting component;

[0010] A battery lock bracket, a portion of which is located between the cover plate lock bracket and the mounting component;

[0011] Fasteners are located outside the mounting component, with one end of the fastener passing through the mounting component and the battery lock bracket being fixed to the cover plate lock bracket;

[0012] A cover plate lock assembly is mounted on the cover plate lock bracket and is used to lock the cover plate to the mounting member;

[0013] A battery lock assembly is mounted on the battery lock bracket and is used to lock the battery into the mounting cavity.

[0014] As an optional solution for the locking and unlocking device, a battery holder is provided in the mounting cavity, the battery lock assembly and the battery holder are spaced apart in the battery extension direction, and the distance between the battery lock assembly and the battery holder is adjustable.

[0015] As an alternative to the locking and unlocking device, the battery lock bracket has a guide groove through which the fastener passes, the length of the guide groove in the battery extension direction being greater than the width of the fastener in that direction.

[0016] As an optional solution for the locking and unlocking device, the guide groove is a U-shaped groove, and the fastener can enter the U-shaped groove from the opening of the U-shaped groove.

[0017] As an optional solution for the locking and unlocking device, the battery lock bracket includes a first mounting portion and a second mounting portion connected to the first mounting portion. The first mounting portion is sandwiched between the mounting member and the cover lock bracket, and the second mounting portion extends to the bottom of the cover lock bracket and is used to install the battery lock assembly.

[0018] As an alternative to the locking and unlocking device, the battery lock bracket includes two second mounting portions, which are connected to both ends of the first mounting portion and make the battery lock bracket U-shaped.

[0019] As an optional embodiment of the locking and unlocking device, the fastener includes a pressing part and a connecting part. The pressing part is located outside the mounting component, and the connecting part passes through the mounting component and the battery lock bracket and is detachably and fixedly connected to the cover plate lock bracket.

[0020] As an optional embodiment of the locking and unlocking device, the cover plate lock assembly includes a locking cover located outside the mounting member. The locking cover is movable along the outer wall of the mounting member to have a cover plate locking position that covers the cover plate and a cover plate unlocking position that avoids the cover plate.

[0021] As an optional solution for the locking and unlocking device, the battery lock assembly includes a base, a bolt, and a bolt drive structure. The base is provided with a clearance hole for the bolt to pass through. The output end of the bolt drive structure is connected to the bolt and can drive the bolt to pass through the clearance hole and extend into the mounting cavity to cooperate with the battery or exit the mounting cavity.

[0022] On the other hand, this application provides an electric bicycle, including a mounting component, a battery, a cover plate, and a locking / unlocking device as described in any of the preceding claims. The mounting component has an open mounting cavity, and the locking / unlocking device is used to lock the battery into the mounting cavity and to lock the cover plate into the open portion of the mounting cavity.

[0023] The advantages of this application are:

[0024] The locking and unlocking device provided in this application includes a cover plate lock bracket, a battery lock bracket, fasteners, a cover plate lock assembly, and a battery lock assembly. Through the cooperation of the cover plate lock bracket, the battery lock bracket, and the fasteners, the cover plate lock assembly and the battery lock assembly are simultaneously installed on the mounting component using the fasteners. This not only saves materials and reduces assembly costs, but also reduces the space occupied by the mounting structure on the mounting component. It eliminates the need to reserve a large installation space on the mounting component, facilitating the lightweight design of the entire vehicle and improving the overall aesthetics of the vehicle.

[0025] The electric bicycle provided in this application, by applying the above-mentioned locking and unlocking device, can lock the cover plate and battery onto the mounting piece, and can achieve a lightweight design of the whole vehicle, improving the overall aesthetics of the vehicle.

[0041] 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.

[0042] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0043] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0044] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0045] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0046] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0047] Figure 1 This is a partial structural diagram of the electric bicycle provided in this embodiment. Figure 2 This is a partially exploded view of the electric bicycle provided in this embodiment. Figures 1 to 2 As shown, the electric bicycle includes a mounting component 100, a battery 300, and a cover plate 200. The mounting component 100 has an open mounting cavity 101, in which the battery 300 is installed. The cover plate 200 is used to cover the openness of the mounting cavity 101 to prevent the battery 300 from being exposed. This not only improves the overall aesthetics of the bicycle but also protects the battery 300 and extends its lifespan. It should be noted that the mounting component 100 can be the downtube of the electric bicycle frame or other parts of the electric bicycle frame; there are no restrictions here.

[0048] Furthermore, the aforementioned electric bicycle also includes a locking and unlocking device, which includes a cover plate lock assembly 4 and a battery lock assembly 5. The battery lock assembly 5 can be used to lock the battery 300 in the mounting cavity 101 to ensure the stability of the electrical connection between the battery 300 and other components and to ensure a stable power supply. The cover plate lock assembly 4 can be used to lock the cover plate 200 onto the mounting member 100 to prevent the cover plate 200 from falling off and to improve the stability of the cover plate 200 installation.

[0049] In electric bicycles, since the relative positions of the cover plate 200 and the mounting component 100 are fixed, if the battery lock assembly 5 and the cover plate lock assembly 4 are installed independently, two sets of mounting structures are required to install the battery lock mechanism and the cover plate lock mechanism on the mounting component 100. This not only increases material and assembly costs, but also requires more installation space, making the frame larger and heavier. At the same time, it requires more processing steps for the frame, such as opening more mounting holes or adding other auxiliary components. This is not conducive to the lightweight design of the whole vehicle and reduces the aesthetics of the whole vehicle.

[0050] To address the aforementioned issues, the locking and unlocking device in this embodiment improves the installation method of the battery lock assembly 5 and the cover plate lock assembly 4, enabling the installation of both lock assemblies through a single installation structure. This not only reduces material and assembly costs but also eliminates the need for a large installation space on the mounting component 100, facilitating lightweight design of the entire vehicle and enhancing its aesthetics.

[0051] Figure 3 A partial structural diagram of the locking and unlocking device provided in this embodiment installed on the mounting member 100 is shown. Figure 4 An exploded view of the locking and unlocking device provided in this embodiment is shown. Figures 3 to 4 As shown, the locking and unlocking device also includes a cover plate lock bracket 1, a battery lock bracket 2, and a fastener 3. The cover plate lock bracket 1 is located inside the mounting component 100, a portion of the battery lock bracket 2 is located between the cover plate lock bracket 1 and the mounting component 100, and the fastener 3 is located outside the mounting component 100, with one end of the fastener 3 passing through the mounting component 100 and the battery lock bracket 2 and being fixedly connected to the cover plate lock bracket 1. The cover plate lock assembly 4 is mounted on the cover plate lock bracket 1, and the battery lock assembly 5 is mounted on the battery lock bracket 2. This locking and unlocking device, through the cooperation of the cover plate lock bracket 1, the battery lock bracket 2, and the fastener 3, enables the simultaneous mounting of both the cover plate lock assembly 4 and the battery lock assembly 5 onto the mounting component 100 using the fastener 3. This not only saves materials and reduces assembly costs but also reduces the space occupied by the mounting structure on the mounting component 100, eliminating the need for a large installation space on the mounting component 100, facilitating lightweight design of the entire vehicle and improving its aesthetics.

[0052] In this embodiment, the fastener 3 is detachably and fixedly connected to the cover plate lock bracket 1. The fastener 3 includes a pressing part 31 and a connecting part 32. The pressing part 31 is located outside the mounting member 100, and the connecting part 32 passes through the mounting member 100 and the battery lock bracket 2 and is detachably and fixedly connected to the cover plate lock bracket 1. For example, the fastener 3 can be a nut bolt, and the cover plate lock bracket 1 is provided with a threaded hole for threaded connection with the nut bolt. To facilitate the fastener 3 passing through the mounting member 100, a through hole is provided on the mounting member 100. For example, the cover plate lock bracket 1 can be fixed by two fasteners 3.

[0053] In another embodiment, the locking and unlocking device may only include a cover plate lock bracket 1, a fastener 3, and a cover plate lock assembly 4. The cover plate lock assembly 4 can be installed on the mounting member 100 by means of the fastener 3 and the cover plate lock bracket 1. For ease of description, the combination having the cover plate lock bracket 1, the fastener 3, and the cover plate lock assembly 4 is referred to as the cover plate lock mechanism.

[0054] In another embodiment, the locking and unlocking device may include only a cover plate lock bracket 1, a fastener 3, a battery lock bracket 2, and a battery lock assembly 5. The battery lock bracket 2 is mounted on the mounting member 100 via the cover plate lock bracket 1 and the fastener 3, thereby enabling the battery lock assembly 5 to be mounted on the mounting member 100. The cover plate lock bracket 1 may have the same structure as in the above embodiment, or it may have a different structure, as long as it can cooperate with the fastener 3 to clamp and mount the battery lock bracket 2 onto the mounting member 100; no limitation is made here. Alternatively, the locking and unlocking device may include only the battery lock bracket 2 and the battery lock assembly 5, wherein the battery lock bracket 2 is fixed to the mounting member 100 by other means, such as by opening additional mounting holes in the mounting member 100 and using screws or other fasteners 3 to mount the battery lock bracket 2 onto the mounting member 100, thereby enabling the battery lock assembly 5 to be mounted on the mounting member 100. As can be seen from the above embodiments, for ease of description, the combination having the battery lock bracket 2 and the battery lock assembly 5 is referred to as a battery lock mechanism. The battery lock bracket 2 in the battery lock mechanism can be installed on the mounting part 100 via the cover plate lock bracket 1 and fastener 3, or it can be installed on the mounting part 100 via other mounting structures.

[0055] In this embodiment, as Figure 4 Combination Figure 2 As shown, the electric bicycle typically also includes a battery holder 400, which is screwed onto the mounting member 100 and located in the mounting cavity 101. The battery holder 400 and the battery lock assembly 5 are spaced apart in the extending direction of the battery 300 to enable the battery 300 to be installed between the battery holder 400 and the battery lock assembly 5.

[0056] If both the battery lock assembly 5 and the battery holder 400 are fixed to the mounting component 100, keeping the distance between them constant, the distance between the battery holder 400 and the battery lock assembly 5 is usually designed to be slightly larger than the length of the battery 300 to ensure smooth assembly of the battery 300, due to the tolerance in the length of the battery 300. However, this design greatly increases the risk of the battery 300 wobbling during riding, which is detrimental to the stability of the battery 300 and affects the stable power supply.

[0057] To address the aforementioned issues, this embodiment provides an adjustable distance between the battery lock bracket 2 and the battery holder 400 to accommodate batteries 300 of varying lengths, ensuring the stability of the battery 300 installation. In this embodiment, the fixed position of the battery lock bracket 2 on the mounting component 100 is adjustable along the extension direction of the battery 300, thereby adjusting the distance between the battery lock bracket 2 and the battery holder 400 to accommodate batteries 300 of different lengths, ensuring the stability of the battery 300 installation, reducing the risk of battery 300 wobbling during riding, and preventing poor charging and discharging of the battery 300 due to inadequate locking.

[0058] Furthermore, the battery lock bracket 2 has a guide groove 211 through which the fastener 3 passes. The extension direction of the guide groove 211 is perpendicular to the extension direction of the fastener 3, and the length of the guide groove 211 in the extension direction of the battery 300 is greater than the length of the fastener 3 in that direction. When the position of the battery lock bracket 2 needs to be adjusted, the fastener 3 is first loosened. At this time, the distance between the cover plate lock bracket 1 and the mounting member 100 increases, and the space in which the battery lock bracket 2 is located becomes larger, allowing it to move. Then, the position of the battery lock bracket 2 is adjusted to the desired position, and then the fastener 3 is tightened until the cover plate lock bracket 1 and the mounting member 100 clamp and fix the battery lock bracket 2. During the adjustment process, since part of the structure of the fastener 3 is located in the guide groove 211 of the battery lock bracket 2, the fastener 3 can serve as a guide structure for the movement of the battery lock bracket 2, ensuring that the battery lock bracket 2 can be stably adjusted in position.

[0059] In this embodiment, the guide groove 211 is a U-shaped groove, allowing the fastener 3 to enter the U-shaped groove from its opening. During installation, the cover plate lock bracket 1 and the fastener 3 are assembled first, and then the battery lock bracket 2 is inserted from the opening of the mounting cavity 101, pushing the battery lock bracket 2 until the fastener 3 enters the U-shaped groove from its opening. This U-shaped groove design facilitates the installation of the battery lock bracket 2. Alternatively, in other embodiments, the guide groove 211 can be an elongated hole, with a length greater than the length of the part where the fastener 3 mates with the elongated hole. During installation, the fastener 3 passes sequentially through the mounting component 100, the guide groove 211 of the battery lock bracket 2, and is fixedly connected to the cover plate lock bracket 1.

[0060] In this embodiment, the battery lock bracket 2 includes a first mounting portion 21 and a second mounting portion 22 connected to the first mounting portion 21. The first mounting portion 21 is sandwiched between the mounting member 100 and the cover plate lock bracket 1, and the second mounting portion 22 extends to the bottom of the cover plate lock bracket 1 and is used to install the battery lock mechanism. Further, the battery lock bracket 2 includes two second mounting portions 22, which are connected to both ends of the first mounting portion 21, making the battery lock bracket 2 U-shaped. A guide groove 211 is provided on the first mounting portion 21, and the battery lock assembly 5 is mounted on the two second mounting portions 22. This battery lock bracket 2 facilitates the installation of the battery lock assembly 5, ensures the stability of the battery lock assembly 5, and thus ensures the stability of the battery 300.

[0061] Figure 5 A partial cross-sectional view is shown of the locking and unlocking device provided in this embodiment mounted on the mounting member 100. (See attached image.) Figure 5 Combination Figure 4As shown, the battery lock assembly 5 includes a base 51, a latch 52, and a latch drive structure 53. The base 51 has a clearance hole 511 for the latch 52 to pass through. The output end of the latch drive structure 53 is connected to the latch 52 and can drive the latch 52 through the clearance hole 511 to extend into the mounting cavity 101 to engage with the battery 300 or to exit the mounting cavity 101. Furthermore, the latch 52 and the base 51 are engaged by an elastic element. When installing the battery 300, the battery 300 can be directly installed into the mounting cavity 101. The battery 300 pushes the latch 52 out of the mounting cavity 101. After the battery 300 is installed, the latch 52 rebounds back into the mounting cavity 101 under the action of the elastic element and engages with the limiting step on the battery 300, thereby locking the battery 300 and preventing the battery 300 from coming out of the mounting cavity 101. When unlocking to remove the battery 300, a key can be inserted into the keyhole of the bolt drive structure 53 to make the bolt 52 exit the mounting cavity 101, so as to remove the battery 300.

[0062] In this embodiment, the base 51 of the battery lock assembly 5 is detachably and fixedly connected to the battery lock bracket 2 by three screws. Of course, in other embodiments, the base 51 may also be fixedly connected to the battery lock bracket 2 by two screws, four screws, or other numbers of screws, and this is not limited here.

[0063] Furthermore, the battery lock assembly 5 also includes a spring clip, one end of which is mounted on the base 51, and the other end of which can abut against the battery 300. This spring clip provides a pre-tightening force for the installation of the battery 300, reducing the risk of the battery 300 shaking within the mounting cavity 101 and improving the stability of the battery 300. In this embodiment, the base 51 may be made of plastic, and the spring clip may be made of metal.

[0064] Figure 6 An exploded view of the cover plate locking mechanism provided in this embodiment is shown. Figure 6 Combination Figures 1 to 3 As shown, the cover lock assembly 4 includes a lock cover 41 located outside the mounting member 100. The lock cover 41 is movable along the outer wall of the mounting member 100 to have a cover lock position that covers the cover 200 and a cover unlock position that avoids the cover 200. Furthermore, the lock cover 41 is reciprocating along the extension direction of the battery 300. When it is necessary to lock the cover 200, the lock cover 41 is moved towards the cover 200 until it is above the cover 200. Thus, the lock cover 41 abuts against the outer side of the cover 200, thereby preventing the cover 200 from detaching from the mounting member 100.

[0065] To improve the stability of the cover plate 200 during installation, a latching protrusion is provided at the end of the cover plate 200 away from the locking cover member 41, and a locking groove is provided on the inner wall of the mounting member 100 to cooperate with the latching protrusion. When installing the cover plate 200, first engage the latching protrusion at one end of the cover plate 200 with the locking groove on the mounting member 100, then press the other end of the cover plate 200 to the opening of the mounting cavity 101, and finally push the locking cover member 41 onto the cover plate 200, thus achieving the limiting of both ends of the cover plate 200. In other words, one end of the cover plate 200 engages with the locking groove of the mounting member 100 through the latching protrusion, and the locking groove of the mounting member 100 restricts the tendency of one end of the cover plate 200 to move outwards from the mounting cavity 101. The other end of the cover plate 200 is restricted from moving outwards from the mounting cavity 101 by the locking cover member 41, thereby firmly locking the cover plate 200 onto the mounting member 100. Of course, in another embodiment, the inner wall of the mounting member 100 may not be provided with a slot, but only with a protrusion on the cover plate 200. After the protrusion is inserted into the mounting cavity 101 of the mounting member 100, it directly abuts against the inner wall of the mounting member 100, which can also achieve the limitation of the cover plate 200.

[0066] The cover lock assembly 4 also includes a locking guide 42 and an elastic member 43. The elastic member 43 is installed between the locking guide 42 and the cover lock bracket 1 and is used to move the locking guide 42 outward of the mounting member 100 to lock the cover 41 in the locked position. Pressing the locking guide 42 inward of the mounting member 100 allows the cover 41 to be in a movable state, so as to adjust the cover 41 to the unlocked position. The locking guide 42 and the elastic member 43 allow the state of the cover 41 to be adjusted by pressing, which improves the convenience of operation. During operation, when the cover 200 needs to be removed from the mounting member 100, first press the locking guide 42 inward of the mounting member 100 (in actual operation, the locking guide 42 can be pressed directly), then push the cover 41 away from the cover 200 so that the cover 41 moves away from the cover 200, and finally remove the cover 200. When the cover plate 200 needs to be installed on the mounting part 100, the locking cover 41 is in the locked position due to the action of the elastic member 43. At this time, it is necessary to first press the locking guide 42 inward towards the mounting part 100, and then push the locking cover 41 away from the cover plate 200 so that the locking cover 41 moves away from the cover plate 200. After the battery 300 is installed in the mounting cavity 101, push the locking cover 41 to the locked position, and then release the locking guide 42 to lock the locking cover 41 to the locked position.

[0067] In this embodiment, the cover lock assembly 4 includes a cover 41, a locking guide 42, and an elastic member 43. The cover 41 is located outside the mounting member 100 and can move along the outer wall of the mounting member 100 so that it has a cover lock position that covers the cover 200 and a cover unlock position that avoids the cover 200. The locking guide 42 is reciprocally mounted on the cover lock bracket 1 in the opening direction. The elastic member 43 is located between the locking guide 42 and the cover lock bracket 1 and is used to move the locking guide 42 in the direction of the mounting member 100 to lock the cover 41 in the cover lock position. Pressing the locking guide 42 in the direction of the mounting member 100 can make the cover 41 movable to adjust the cover 41 to be in the cover unlock position. Of course, in other embodiments, the cover lock assembly 4 may also include a cover lock 41 and a cover lock drive, wherein the cover lock 41 is driven to rotate by the cover lock drive, thereby enabling the cover lock 41 to switch between the cover lock position and the cover unlock position.

[0068] Furthermore, in order to facilitate the movement of the locking cover 41, a pushing part is provided on the locking cover 41, and the pushing part is provided with anti-slip texture to facilitate the operation of the operator.

[0069] continue Figure 6 Combination Figure 3 As shown, the cover plate lock assembly 4 also includes a fixing piece 45 located outside the mounting member 100. The fixing piece 45 covers the lock cover 41, and both ends of the fixing piece 45 extend beyond the lock cover 41 and are fixed to the mounting member 100 by fasteners 3, thereby installing the lock cover 41 onto the mounting member 100.

[0070] Furthermore, the fixing piece 45 includes a pressing part 451 and a first fixing part 452 and a second fixing part 453 connected to both ends of the pressing part 451. The pressing part 451 has a recessed side facing the locking cover 41 to form a receiving space for accommodating the locking cover 41. The depth of the receiving space is not less than the thickness of the mating part between the locking cover 41 and the receiving space, so as to prevent the fixing piece 45 from locking the locking cover 41 onto the mounting member 100 and to ensure that the locking cover 41 can move relative to the fixing piece 45. In this embodiment, the fixing piece 45 is shaped like a "Z".

[0071] Figure 7 A cross-sectional schematic diagram of the cover plate locking mechanism provided in this embodiment is shown. Figure 7 Combination Figure 6As shown, the locking guide 42 includes a limiting part 422, and the locking cover 41 has a limiting guide hole 411. When the locking guide 42 is not subjected to a pressing force, the limiting part 422 is located in the limiting guide hole 411, and the distance between the limiting part 422 and the inner wall of the limiting guide hole 411 near the cover plate 200 is less than the distance required for the locking cover 41 to move from the locked position of the cover plate to the unlocked position of the cover plate. When the locking guide 42 is subjected to a pressing force, the limiting part 422 can exit the limiting guide hole 411 so that the locking cover 41 is in a movable state. In other words, when the locking guide 42 moves outward from the mounting 100 under the action of the elastic member 43, the limiting part 422 can extend into the limiting guide hole 411 and abut against the hole wall of the limiting guide hole 411, so that the lock cover 41 is in the locked position; when the locking guide 42 moves inward from the mounting 100 under the pressing force, the limiting part 422 can exit the limiting guide hole 411, so that the lock cover 41 is in a movable state.

[0072] To facilitate pressing operation, the locking guide 42 also includes a guiding pressing part 423. The guiding pressing part 423 passes through the limiting guide hole 411 and extends to the outside of the mounting part 100. When the locking guide 42 is not subjected to pressing force, the height of the guiding pressing part 423 extending beyond the upper surface of the lock cover 41 is greater than the depth of the limiting part 422 extending into the limiting guide hole 411.

[0073] In this embodiment, the locking guide 42 further includes a main body 421, a limiting part 422 and a guiding pressing part 423, both located above the main body 421, with the guiding pressing part 423 higher than the limiting part 422. When the locking guide 42 is only subjected to the elastic force of the elastic member 43, the guiding pressing part 423 extends outside the lock cover 41 to facilitate pressing by the operator. The limiting part 422 can just extend into the limiting guide hole 411 of the lock cover 41, and the distance between the limiting part 422 and the inner wall of the limiting guide hole 411 near the cover plate 200 is less than the distance required for the lock cover 41 to move from the lock position to the unlock position. When the locking guide 42 is subjected to an external pressing force, the locking guide 42 moves downward until the limiting part 422 exits the limiting guide hole 411 of the lock cover 41, facilitating the movement of the lock cover 41 to the unlock position.

[0074] Furthermore, to avoid interference between the guide pressing part 423 and the clamping part 451 of the fixing plate 45, a relief groove 4511 is provided on the clamping part 451 of the fixing plate 45 at a position corresponding to the guide pressing part 423, so that the guide pressing part 423 can extend out. This design, while reserving space for the movement of the guide pressing part 423 of the locking guide member 42, can ensure that the fixing plate 45 covers the locking cover member 41 over a large area, thus ensuring the stability of the locking cover member 41.

[0075] It should be noted that, in order to ensure that the locking cover 41 can smoothly switch between the locked and unlocked positions, the length of the limiting guide hole 411 must be greater than the sum of the width of the guide pressing part 423 in the direction of movement and the distance between the locked and unlocked positions of the cover. This design is readily conceived by technicians familiar with the working principle of the cover locking mechanism and will not be elaborated upon here.

[0076] To ensure the stable movement of the locking guide 42, the cover plate lock bracket 1 has a guide channel 11 extending along the movement direction of the locking guide 42, and the locking guide 42 is slidably disposed within the guide channel 11. Through the limiting and guiding effect of the guide channel 11, the locking guide 42 can be stably raised and lowered along the guide channel 11 without misalignment, ensuring the normal operation of the cover plate lock mechanism.

[0077] Furthermore, the cover plate lock bracket 1 has a groove 12 communicating with the guide channel 11. Part of the elastic member 43 is accommodated in the groove 12, and the part of the elastic member 43 outside the groove 12 abuts against the locking guide member 42. By providing the groove 12, the elastic member 43 can be accommodated on the one hand, and the elastic member 43 can also be limited on the other hand, to prevent the elastic member 43 from being misaligned and affecting the stable operation of the locking guide member 42.

[0078] To prevent the locking guide 42 from moving too much upward under the action of the elastic member 43, the cover lock assembly 4 also includes a connector 44. The cover lock bracket 1 has a guide hole that slides with the connector 44. The connector 44 includes a stop portion 441 and a guide connecting portion 442. The stop portion 441 is located outside the guide hole, and the guide connecting portion 442 passes through the guide hole and is fixedly connected to the locking guide 42. With this configuration, when the stop portion 441 of the connector 44 abuts against the cover lock bracket 1, the locking guide 42 cannot continue to move upward even under the force of the elastic member 43, thereby limiting the movement stroke of the locking guide 42.

[0079] In summary, the locking and unlocking device provided in this embodiment, by using a common fixing structure to install the battery lock mechanism and the cover lock mechanism on the mounting part 100, not only reduces material costs but also simplifies assembly and shortens assembly time. By adjusting the battery lock mechanism to be installed on the mounting part 100 along the extension direction of the battery 300, the stable installation of the battery 300 can be ensured, reducing the risk of the battery 300 shaking during riding. Locking and unlocking the cover lock mechanism by pressing simplifies operation and improves ease of use.

[0080] The foregoing has shown and described the basic principles, main features, and advantages of this application. 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.
