[0003] The present application relates to the field of battery technology, and in particular to a locking mechanism, a battery assembly, an electrical device, and a locking device. Background Art

[0004] With the advancement of science and technology, the battery industry has developed rapidly, and the market share and frequency of use of electric equipment are also increasing. Electric vehicles such as electric vehicles are gradually appearing in various application scenarios. At the same time, in order to improve the convenience of electric equipment, especially electric vehicles, battery swap stations for rapid battery replacement have appeared on the market. However, electric equipment needs to be frequently replaced. During the battery replacement process, the locking mechanism between the battery and the power-consuming equipment needs to be switched between locking and unlocking multiple times to lock and separate the battery and the power-consuming equipment. As a result, the locking mechanism is prone to wear or damage, resulting in a short service life of the locking mechanism and poor reliability, which in turn leads to inconvenience in battery replacement and safety hazards in use.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a locking mechanism, a battery assembly, an electrical device, and a locking device, which can effectively improve the service life and reliability of the locking mechanism.

[0007] and a locking mechanism for engaging with or disengaging from a lock seat in a first direction. The locking mechanism comprises a sleeve, a locking member, an adjusting member, and a fastening assembly; the locking member is movably arranged on the sleeve, and the locking member has a locked state and an unlocked state, the locking member being configured to engage with the lock seat when in the locked state so that the locking mechanism and the lock seat are engaged in the first direction, and the locking member is configured to disengage from the lock seat when in the unlocked state to allow the locking mechanism and the lock seat to disengage in the first direction; the adjusting member is rotatably connected to the sleeve around an axis extending in the first direction, the adjusting member is threadedly connected to the locking member, and the adjusting member is configured to drive the locking member to move relative to the sleeve when rotating relative to the sleeve, so that the locking member switches between the locked state and the unlocked state; the fastening assembly is configured to prevent the locking member from moving relative to the adjusting member in the first direction along the direction of the adjusting member pointing to the lock seat when the locking member is in the locked state.

[0008] In the above technical solution, the locking mechanism is provided with a locking member and an adjusting member. By threading the locking member and the adjusting member, the locking member can be driven to move relative to the sleeve when the adjusting member is rotated, thereby realizing the switching of the locking member between a locked state and an unlocked state, so that the locking member can be engaged or disengaged with the lock seat, thereby realizing the engagement or disengagement of the locking mechanism and the lock seat along the first direction. When the locking member is in the locked state, the locking member is prevented from moving relative to the adjusting member in the direction of the adjusting member pointing to the lock seat. That is, when the locking member is engaged with the lock seat so that the locking mechanism and the lock seat are engaged in the first direction, the locking member and the adjusting member can be further locked under the action of the fastening member, so that the locking member cannot move relative to the adjusting member in the direction closer to the lock seat, thereby further preventing the locking member from disengaging from the adjusting member in the first direction. The locking mechanism with such a structure can, on the one hand, further reduce the risk of the locking member and the adjusting member being disengaged from each other when the locking member and the lock seat are engaged with each other, thereby improving the stability and reliability of the mutual locking between the locking mechanism and the lock seat. On the other hand, the fastening member can transfer the force of the threaded structure between the locking member and the adjusting member to the fastening member, thereby alleviating the phenomenon of slipping or damage of the threaded structure between the locking member and the adjusting member, thereby reducing the risk of failure of the threaded connection between the locking member and the adjusting member, thereby facilitating the service life and reliability of the locking mechanism.

[0009] In some embodiments, the fastening assembly is provided on the locking member, the adjusting member has a contact surface, and the fastening assembly is configured to contact the contact surface in a first direction along the direction of the adjusting member pointing to the lock seat when the locking member is in a locked state.

[0010] In the above technical solution, the fastening assembly is arranged on the locking member, and the adjusting member has an abutting surface that abuts against the fastening assembly, so that when the locking member is in a locked state, the fastening assembly can abut against the abutting surface in the first direction along the direction of the adjusting member pointing to the lock seat, so as to prevent the locking member from moving relative to the adjusting member in the first direction along the direction of the adjusting member pointing to the lock seat, thereby transferring the force of the threaded structure between the locking member and the adjusting member to the abutting surface between the fastening assembly and the adjusting member, so as to alleviate the phenomenon of slipping teeth or damage to the threaded structure between the locking member and the adjusting member.

[0011] In some embodiments, the locking member has a mounting portion inserted into the adjusting member along a first direction, and the inner surface of the adjusting member includes a contact surface; the fastening assembly includes a clip, which is movably arranged on the mounting portion, and the clip is used to abut against the contact surface after protruding from the outer peripheral surface of the mounting portion or to release the contact with the contact surface after retracting into the mounting portion.

[0012] In the above technical solution, the locking member has a mounting portion inserted into the interior of the adjusting member, and the abutment surface is located on the inner surface of the adjusting member, so that the clamping member of the fastening assembly can abut against the abutment surface after protruding from the outer peripheral surface of the mounting portion, so as to realize that the fastening assembly prevents the locking member from moving relative to the adjusting member in the first direction along the direction of the adjusting member pointing to the lock seat. Conversely, the clamping member of the fastening assembly can release the abutment from the abutment surface after retreating into the mounting portion, thereby realizing that the locking member can move relative to the adjusting member. The structure is simple and easy to implement.

[0013] In some embodiments, the fastening assembly also includes a moving part; the moving part is movably arranged in the mounting part along a first direction, and the moving part is configured to push the clamping part to protrude out of the outer peripheral surface of the mounting part or allow the clamping part to retreat into the mounting part when it moves relative to the mounting part along the first direction, so that the clamping part abuts or releases the abutment with the abutment surface.

[0014] In the above technical solution, the fastening assembly is also provided with a movable member for pushing the clipping member to protrude from the outer peripheral surface of the mounting portion and allowing the clipping member to retreat into the mounting portion. By arranging the movable member movably along the first direction in the mounting portion, the movable member can push the clipping member to protrude from the outer peripheral surface of the mounting portion and prevent the clipping member from retreating when it moves relative to the mounting portion in one direction of the first direction, and can release the abutment against the clipping member when it moves relative to the mounting portion in the other direction of the first direction to allow the clipping member to retreat into the mounting portion, thereby enabling the clipping member to abut or release the abutment with the abutment surface.

[0015] In some embodiments, the adjusting member is configured to drive the locking member to move between a first position and a second position along a first direction when rotating relative to the sleeve. When the locking member is in the first position, the locking member is in a locked state, and when the locking member is in the second position, the locking member is in an unlocked state; wherein the adjusting member is provided with an execution part, and the execution part is configured to: when the locking member moves from the second position to the first position, it can abut against the moving member and push the moving member to move, so that the moving member can push the clamping member to protrude from the outer peripheral surface of the mounting portion; when the locking member moves from the first position to the second position, it can separate from the moving member, so that the moving member can allow the clamping member to retreat into the mounting portion.

[0016] In the above technical solution, the adjusting member can drive the locking member to switch between the locked state and the unlocked state while also driving the locking member to move relative to the sleeve along the first direction, so that the locking member has a first position and a second position in the first direction. By arranging an executive part on the adjusting member, the executive part can abut against the moving member and push the moving member to move when the locking member moves from the second position to the first position, so that the clip can protrude from the outer peripheral surface of the mounting part under the push of the moving member, and the executive part can also separate from the moving member when the locking member moves from the first position to the second position to release the constraint of the executive part on the moving member, so that the moving member can allow the clip to retreat into the mounting part, thereby enabling the locking member to switch between the locked state and the unlocked state by moving the locking member along the first direction. At the same time, the clip of the fastening assembly can protrude from the outer peripheral surface of the mounting part or allow the clip of the fastening assembly to retreat into the mounting part under the cooperation of the moving member and the executive part, so as to realize the linkage of the locking mechanism, without the need for an additional driving mechanism or manual participation, which is conducive to reducing the operation difficulty of the locking mechanism.

[0017] In some embodiments, the executing portion and the mounting portion are arranged along a first direction, and a protrusion is provided at one end of the executing portion facing the mounting portion, and the protrusion is configured to be inserted into the mounting portion and abut against the moving part.

[0018] In the above technical solution, a protrusion is provided at one end of the executing part facing the mounting part along the first direction, so that the protrusion can be inserted into the mounting part and abut against the moving part when the mounting part approaches the executing part along the first direction, thereby facilitating improving the effect of the executing part in pushing the moving part to move.

[0019] In some embodiments, a accommodating cavity is formed inside the mounting portion, and the accommodating cavity passes through one end of the mounting portion close to the execution portion along the first direction, and the accommodating cavity is used for inserting the protrusion; wherein, the movable part is movably arranged in the accommodating cavity along the first direction, and a mounting hole is provided on the outer peripheral surface of the mounting portion, and the mounting hole is connected to the accommodating cavity, and the clamping part is movably arranged in the mounting hole.

[0020] In the above technical solution, a housing cavity for accommodating the movable member is provided inside the mounting portion, and the housing cavity extends through one end of the mounting portion in a first direction, so that the protrusion of the actuator can be inserted into the housing cavity, thereby enabling the protrusion and the movable member to abut against each other, which helps to simplify the structural complexity of the locking mechanism. In addition, a mounting hole is provided on the outer peripheral surface of the mounting portion that is connected to the housing cavity, and the clamping member is movably provided in the mounting hole. When the movable member moves in the first direction within the housing cavity, it can push the clamping member through the mounting hole to protrude from the outer peripheral surface of the mounting portion, or allow the third clamping member to retract into the mounting portion through the mounting hole. The structure is simple and easy to implement.

[0021] In some embodiments, the fastening assembly also includes a first elastic member; the first elastic member is arranged between the moving member and the mounting portion, and the first elastic member is configured to drive the moving member to move along the first direction toward the execution portion so that the moving member can allow the clamping member to retract into the mounting portion.

[0022] In the above technical solution, a first elastic member is further provided between the movable member and the mounting portion, through which a force can be applied to the movable member along a first direction toward the execution portion, so that the movable member can automatically reset to a position allowing the clamping member to retreat into the mounting portion after being separated from the execution portion. On the one hand, this can alleviate the phenomenon of the clamping member and the adjusting member's abutting surface being mistakenly contacted due to the inability of the movable member to reset, and on the other hand, it does not require manual labor and is easy to operate and use.

[0023] In some embodiments, a first limiting portion is provided inside the mounting portion, and a second limiting portion is provided inside the moving member. The first limiting portion and the second limiting portion cooperate to limit the range of movement of the moving member relative to the mounting portion in the first direction.

Through the cooperation of the first limiting portion and the second limiting portion, the movement range of the movable part relative to the mounting portion in the first direction can be limited. On the one hand, the movable part can be accurately switched along the first direction between the position of pushing the clamping part protruding from the outer peripheral surface of the mounting portion and the position of allowing the clamping part to retreat to the mounting portion, which is beneficial to improving the accuracy of the abutment and release of the abutment between the clamping part and the abutment surface. On the other hand, it can play a certain limiting role on the movable part to reduce the risk of the movable part detaching from the mounting part.

[0025] In some embodiments, the first limiting portion is a limiting block provided on the inner circumference of the mounting portion, and the second limiting portion is a groove provided on the outer circumference of the moving part, and at least a portion of the limiting block is accommodated in the groove.

[0026] In the above technical solution, the first limiting portion and the second limiting portion are respectively a limiting block arranged on the inner circumferential surface of the mounting portion and a groove on the outer circumferential surface of the movable part. By inserting the limiting block into the groove, when the movable part moves relative to the mounting portion, the limiting block can abut against the two groove side walls opposite to each other in the first direction, so as to limit the moving range of the movable part in the first direction under the cooperation of the limiting block and the groove. The structure is simple, easy to implement, and has high stability.

[0027] In some embodiments, the first limiting portion is an annular limiting block extending along the circumference of the moving member, and the second limiting portion is an annular groove extending along the circumference of the moving member.

[0028] In the above technical solution, by setting the first limiting portion and the second limiting portion as annular structures, it is helpful to further improve the stability and reliability of the first limiting portion and the second limiting portion cooperating to limit the moving part.

[0030] In the above technical solution, a guiding slope for the clamping part to abut against is provided on the moving part, so that the clamping part can protrude from the outer peripheral surface of the mounting part under the guidance of the guiding slope when the moving part moves along the first direction, so that the moving part can drive the clamping part to protrude from the outer peripheral surface of the mounting part or allow the clamping part to retreat into the mounting part. The locking mechanism using this structure can reduce the phenomenon of mutual jamming between the moving part and the clamping part.

The structure is simple and easy to operate, and can alleviate the phenomenon that the clamping part cannot be clamped with the lock seat due to the large angle of rotation of the clamping part following the connecting part, which is beneficial to improving the reliability of the mutual locking between the locking mechanism and the lock seat.

[0039] In some embodiments, the third limiting portion and the fourth limiting portion are also configured to cooperate with the guiding connecting portion to move along the first direction when the adjusting member rotates relative to the sleeve, so that the locking member moves between the first position and the second position along the first direction; when the locking member is in the first position, the locking member is in a locked state, so that the clamping portion can be clamped with the lock seat; when the locking member is in the second position, the locking member is in an unlocked state, so that the clamping portion can be released from the lock seat.

By inserting the protrusion into the limiting groove, the rotation angle of the connecting portion is limited under the restriction of the limiting groove, and the protrusion can be guided by the limiting groove to enable the connecting portion to rotate relative to the sleeve and move along the first direction relative to the sleeve at the same time.

DETAILED DESCRIPTION

[0084] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0085] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0086] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0087] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0088] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0089] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0090] The term "plurality" used in this application refers to two or more (including two).

[0091] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0092] The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present application.

[0093] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of a battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator, placed between the positive and negative electrodes, prevents short circuits between the positive and negative electrodes while allowing the active ions to pass through.

[0094] In some embodiments, the positive electrode may be a positive electrode sheet, and the negative electrode may be a negative electrode sheet.

[0095] In some embodiments, the electrode assembly further includes a separator disposed between the positive electrode and the negative electrode.

[0096] In some embodiments, the separator is a separator.

[0097] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.

[0098] As an example, the battery cells may be cylindrical, prismatic, soft-pack or other shaped battery cells. Prismatic battery cells include but are not limited to square-shell, blade-shaped, and polygonal batteries, such as hexagonal batteries.

[0099] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

[0100] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0101] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0102] With technological advancements and the rapid development of new energy vehicles, electric vehicles are gaining increasing market share and increasing in frequency of use. Electric commercial vehicles, such as heavy-duty and light-duty electric trucks, are gradually appearing in various application scenarios, and battery swap stations have been built to accommodate these vehicles.

[0103] In the field of new energy vehicles, electric trucks consume more energy than ordinary passenger cars due to their heavy loads and long driving range. Therefore, to maintain battery life, electric trucks require frequent battery swaps. During this process, the locking, securing, and detaching of the battery from the vehicle are key concerns. To achieve this, the current method primarily involves installing a lock seat on the vehicle and a corresponding locking mechanism on the battery. The locking mechanism's adjustment member can drive the locking member of the locking mechanism to lock or unlock the lock seat, completing the vehicle's battery swapping function. However, the locking part and the adjusting part of the locking mechanism usually adopt a threaded connection structure, so that the adjusting part can drive the locking part to move or rotate. The locking mechanism of this structure is prone to slippage between the locking part and the adjusting part after multiple battery replacements, and the gravity of the battery installed on the vehicle will directly act on the threaded structure between the locking part and the adjusting part, which can easily cause the risk of failure of the threaded connection between the locking part and the adjusting part, resulting in a shorter service life and lower reliability of the locking mechanism between the battery and the vehicle, causing inconvenience in battery replacement and safety hazards in use of electrical equipment.

[0104] Based on the above considerations, in order to address technical issues such as the short service life and low reliability of the locking mechanism between the battery and the vehicle, an embodiment of the present application provides a locking mechanism, which includes a sleeve, a locking member, an adjusting member, and a fastening assembly. The locking member is movably disposed on the sleeve, and the locking member has a locked state and an unlocked state. When in the locked state, the locking member is configured to engage with the lock seat so that the locking mechanism and the lock seat engage in a first direction. When in the unlocked state, the locking member is configured to disengage from the lock seat to allow the locking mechanism and the lock seat to disengage in the first direction. The adjusting member is rotatably connected to the sleeve about an axis extending in the first direction. The adjusting member is threadedly connected to the locking member. The adjusting member is configured to drive the locking member to move relative to the sleeve when rotating relative to the sleeve, so that the locking member switches between the locked state and the unlocked state. The fastening assembly is configured to prevent the locking member from moving relative to the adjusting member in the first direction in the direction from which the adjusting member points to the lock seat when the locking member is in the locked state.

[0105] In the locking mechanism of this structure, the locking mechanism is provided with a locking member and an adjusting member. By threading the locking member and the adjusting member, the locking member can be driven to move relative to the sleeve when the adjusting member is rotated, thereby realizing the switching of the locking member between the locked state and the unlocked state, so that the locking member can be engaged or disengaged with the lock seat, thereby realizing the engagement or disengagement of the locking mechanism and the lock seat along the first direction. When the locking member is in the locked state, the locking member is prevented from moving relative to the adjusting member in the direction of the adjusting member pointing to the lock seat. That is, when the locking member is engaged with the lock seat so that the locking mechanism and the lock seat are engaged in the first direction, the locking member and the adjusting member can be further locked under the action of the fastening member, so that the locking member cannot move relative to the adjusting member in the direction closer to the lock seat, thereby further preventing the locking member from disengaging from the adjusting member in the first direction. The locking mechanism with such a structure can, on the one hand, further reduce the risk of the locking member and the adjusting member being disengaged from each other when the locking member and the lock seat are engaged with each other, thereby improving the stability and reliability of the mutual locking between the locking mechanism and the lock seat. On the other hand, the fastening member can transfer the force of the threaded structure between the locking member and the adjusting member to the fastening member, thereby alleviating the phenomenon of slipping or damage of the threaded structure between the locking member and the adjusting member, thereby reducing the risk of failure of the threaded connection between the locking member and the adjusting member, thereby facilitating the service life and reliability of the locking mechanism.

[0106] The locking mechanism disclosed in the embodiments of this application can be used, but is not limited to, in electrical equipment such as vehicles, ships, or aircraft. A power supply system for such electrical equipment can be constructed using a locking mechanism disclosed in this application and a battery assembly. This can help alleviate issues such as the short service life and low reliability of the locking mechanism, thereby improving the safety of the electrical equipment.

[0107] The present invention provides an electrical device that uses a battery pack as a power source. The electrical device may include, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, and the like. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, and the spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, and the like.

[0108] For the convenience of description, the following embodiments are described by taking a vehicle as an example of an electrical device in an embodiment of the present application.

[0109] Please refer to Figure 1, which is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of the present application. Vehicle 1000 can be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle. A battery assembly 100 is disposed within vehicle 1000. Battery assembly 100 can be disposed at the bottom, front, or rear of vehicle 1000.

[0110] According to some embodiments of the present application, with reference to FIG2 and FIG3 , FIG2 is a schematic diagram of a partial structure of a vehicle 1000 provided in some embodiments of the present application, and FIG3 is an exploded view of a partial structure of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 has a mounting frame 200 and a lock seat 300, the lock seat 300 being mounted on the mounting frame 200, and the battery assembly 100 including a locking mechanism 10 and a battery 20, the locking mechanism 10 being mounted on the battery 20, and the locking mechanism 10 being used to lock or unlock with the lock seat 300 to enable battery replacement of the vehicle 1000. The battery 20 can be used to power the vehicle 1000, for example, the battery 20 can serve as an operating power source or a power source for the vehicle 1000.

[0111] Optionally, as shown in FIG1 , the vehicle 1000 may further include a controller 400 and a motor 500 , wherein the controller 400 is used to control the battery 20 to supply power to the motor 500 , for example, to meet the power requirements for starting, navigating, and driving the vehicle 1000 .

[0112] In some embodiments of the present application, the battery 20 can not only serve as the operating power source or usage power source of the vehicle 1000, but also serve as the driving power source of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0113] Referring to Figure 3 and further to Figure 4, which is an exploded view of a battery 20 according to some embodiments of the present application, the battery 20 may include a housing 21 and a battery cell 22. The battery cell 22 is housed within the housing 21, and the locking mechanism 10 is mounted on the housing 21.

[0114] The housing 21 is used to provide assembly space for the battery cells 22, and the housing 21 can adopt a variety of structures. In some embodiments, the housing 21 can include a first housing body 211 and a second housing body 212. The first housing body 211 and the second housing body 212 cover each other, and the first housing body 211 and the second housing body 212 jointly define an assembly space for accommodating the battery cells 22. The first housing body 211 and the second housing body 212 can each be a hollow structure with one side open, and the open side of the first housing body 211 covers the open side of the second housing body 212, so that the first housing body 211 and the second housing body 212 jointly define an assembly space. Exemplarily, the locking mechanism 10 can be installed on the first housing body 211 or the second housing body 212.

[0115] In other embodiments, the box body 21 may also have other structures. For example, the second box body 212 may be a hollow structure with one end open, and the first box body 211 may be a plate-like structure. The first box body 211 covers the open side of the second box body 212, so that the first box body 211 and the second box body 212 jointly define an assembly space. Of course, the box body 21 formed by the first box body 211 and the second box body 212 can have various shapes, such as a cylinder, a rectangular parallelepiped, etc. For example, in FIG4 , the box body 21 is in the shape of a rectangular parallelepiped.

[0116] In the battery 20, there may be one or more battery cells 22 disposed in the housing 21. When there are multiple battery cells 22 disposed in the housing 21, the multiple battery cells 22 may be connected in series, in parallel, or in a mixed connection. Mixed connection means that the multiple battery cells 22 are connected in series and in parallel. The multiple battery cells 22 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 22 may be accommodated in the housing 21. Of course, the battery 20 may also be a battery module formed by first connecting multiple battery cells 22 in series, in parallel, or in a mixed connection, and then the multiple battery modules may be connected in series, in parallel, or in a mixed connection to form a whole, and then accommodated in the housing 21. In some embodiments, the battery 20 may also include other structures. For example, the battery 20 may also include a busbar component, which is used to connect the multiple battery cells 22 to achieve electrical connection between the multiple battery cells 22.

[0117] Each battery cell 22 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 22 can be cylindrical, flat, rectangular, or in other shapes. For example, in FIG4 , the battery cell 22 is a rectangular parallelepiped.

[0118] According to some embodiments of the present application, referring to FIG3 and further referring to FIG5, FIG6, and FIG7, FIG5 is a schematic structural diagram of a locking mechanism 10 provided in some embodiments of the present application, FIG6 is an exploded structural diagram of a locking mechanism 10 provided in some embodiments of the present application, and FIG7 is a cross-sectional view of a locking mechanism 10 (when the locking member 12 is in a locked state) provided in some embodiments of the present application. The present application provides a locking mechanism 10 for engaging or disengaging with a lock base 300 along a first direction X. The locking mechanism 10 includes a sleeve 11, a locking member 12, an adjusting member 13, and a fastening assembly 14. The locking member 12 is movably disposed within the sleeve 11 and has a locked state and an unlocked state. When in the locked state, the locking member 12 is configured to engage with the lock base 300 to engage the locking mechanism 10 with the lock base 300 in a first direction X. When in the unlocked state, the locking member 12 is configured to disengage from the lock base 300 to allow the locking mechanism 10 to disengage from the lock base 300 in the first direction X. An adjusting member 13 is rotatably coupled to the sleeve 11 about an axis extending in the first direction X. The adjusting member 13 is threadedly coupled to the locking member 12. The adjusting member 13 is configured to drive the locking member 12 relative to the sleeve 11 when rotating relative to the sleeve 11, thereby switching the locking member 12 between the locked and unlocked states. A fastening assembly 14 is configured to prevent the locking member 12 from moving relative to the adjusting member 13 in the first direction X, in a direction directed toward the lock base 300 by the adjusting member 13, when the locking member 12 is in the locked state.

[0119] Among them, the locking member 12 is used to engage or disengage with the lock base 300, so that the locking mechanism 10 can engage or disengage with the lock base 300 along the first direction X through the locking member 12, thereby realizing locking or unlocking between the locking mechanism 10 and the lock base 300.

[0120] The locking member 12 is movable relative to the sleeve 11 , so that the locking member 12 has a locked state in which it can be engaged with the lock base 300 and an unlocked state in which it is released from the lock base 300 . The structure of the locking member 12 can be various. For example, in Figures 6 and 7, the locking member 12 includes a connecting portion 121 and a clamping portion 122. The connecting portion 121 extends along the first direction X and is inserted into the sleeve 11. The connecting portion 121 is threadedly connected to the adjusting member 13. The clamping portion 122 is located outside the sleeve 11 and is connected to the end of the connecting portion 121 away from the sleeve 11. The clamping portion 122 protrudes from the outer peripheral surface of the connecting portion 121 along its extension direction. The clamping portion 122 is used to clamp with the lock seat 300. The extension direction of the clamping portion 122 is perpendicular to the first direction X, so that the locking member 12 is an irregular structure that can be rotated around an axis extending in the first direction X, so that the clamping portion 122 can be driven to rotate by rotating the connecting portion 121, so that the clamping portion 122 can be clamped or released with the lock seat 300. Of course, in other embodiments, the locking member 12 may also be a structure that is retractable in a direction perpendicular to the first direction X, so that the locking member 12 can be engaged with or disengaged from the lock base 300 .

[0121] The adjusting member 13 is threadedly connected to the locking member 12, that is, the locking member 12 is threadedly connected to the adjusting member 13. The locking member 12 can be inserted into the adjusting member 13, the locking member 12 has an external thread, the adjusting member 13 has an internal thread, and the locking member 12 is threadedly connected to the adjusting member 13. Alternatively, the adjusting member 13 can be inserted into the locking member 12, the locking member 12 has an internal thread, the adjusting member 13 has an external thread, and the locking member 12 is threadedly connected to the adjusting member 13. For example, in FIG7 , the connecting portion 121 of the locking member 12 is inserted into the adjusting member 13, the connecting portion 121 has an external thread, and the adjusting member 13 has an internal thread, so as to achieve the threaded connection between the adjusting member 13 and the locking member 12.

[0122] The adjusting member 13 is configured to drive the locking member 12 to move relative to the sleeve 11 when rotating relative to the sleeve 11, so that the locking member 12 switches between the locked state and the unlocked state. That is, by rotating the adjusting member 13 relative to the sleeve 11, the adjusting member 13 can drive the locking member 12 to move relative to the sleeve 11, so that the locking member 12 switches between the locked state and the unlocked state. For example, in FIG7 , rotating the adjusting member 13 can drive the connecting portion 121 of the locking member 12 to rotate relative to the sleeve 11, so that the connecting portion 121 drives the engaging portion 122 to rotate, thereby enabling the engaging portion 122, whose extending direction is perpendicular to the first direction X, to rotate within a plane perpendicular to the first direction X, so that the engaging portion 122 can engage or disengage with the lock base 300, so that the locking member 12 switches between the locked state and the unlocked state.

[0123] The fastening assembly 14 is configured to prevent the locking member 12 from moving relative to the adjusting member 13 in the first direction X along the direction from the adjusting member 13 to the lock seat 300 when the locking member 12 is in the locked state. That is, when the locking member 12 is engaged with the lock seat 300, the fastening assembly 14 can limit the locking member 12 from moving in the first direction X from the sleeve 11 to the engaging portion 122.

[0124] The locking mechanism 10 is provided with a locking member 12 and an adjusting member 13. By threading the locking member 12 and the adjusting member 13, when the adjusting member 13 is rotated, the locking member 12 can be driven to move relative to the sleeve 11, thereby realizing the switching of the locking member 12 between the locked state and the unlocked state, so that the locking member 12 can be engaged or disengaged with the lock seat 300, thereby realizing the engagement or disengagement of the locking mechanism 10 and the lock seat 300 along the first direction X. By arranging the fastening assembly 14 on the locking mechanism 10, the fastening assembly 14 can prevent the locking member 12 from moving relative to the adjusting member 13 in the first direction X along the direction in which the adjusting member 13 points to the lock seat 300 when the locking member 12 is in the locked state. That is, when the locking member 12 is engaged with the lock seat 300 to achieve the engagement of the locking mechanism 10 and the lock seat 300 along the first direction X, the locking member 12 and the adjusting member 13 can be further locked under the action of the fastening assembly 14, so that the locking member 12 cannot move relative to the adjusting member 13 in the direction close to the lock seat 300, thereby further preventing the locking member 12 from separating from the adjusting member 13 along the first direction X. On the one hand, the locking mechanism 10 can further reduce the risk of the locking member 12 and the adjusting member 13 being disengaged from each other when the locking member 12 and the lock base 300 are engaged with each other, so as to improve the stability and reliability of the mutual locking between the locking mechanism 10 and the lock base 300. On the other hand, the fastening component 14 can transfer the force of the threaded structure between the locking member 12 and the adjusting member 13 to the fastening component 14, thereby alleviating the phenomenon of slipping or damage to the threaded structure between the locking member 12 and the adjusting member 13, so as to reduce the risk of failure of the threaded connection between the locking member 12 and the adjusting member 13, which is beneficial to improving the service life and reliability of the locking mechanism 10.

[0125] According to some embodiments of the present application, referring to Figures 6 and 7, and further referring to Figure 8, which is a partial enlarged view of the locking mechanism 10 at point A shown in Figure 7, a fastening assembly 14 is provided on the locking member 12, and the adjusting member 13 has an abutting surface 131. The fastening assembly 14 is configured to abut against the abutting surface 131 in a first direction X along a direction of the adjusting member 13 pointing toward the lock seat 300 when the locking member 12 is in the locked state.

[0126] The locking member 12 has a mounting portion 123 inserted into the adjusting member 13. The mounting portion 123 is connected to an end of the connecting portion 121 that is away from the engaging portion 122 in the first direction X. The fastening assembly 14 is disposed on the mounting portion 123 of the locking member 12. Of course, in other embodiments, the fastening assembly 14 may also be disposed on the adjusting member 13. Correspondingly, the locking member 12 is provided with an abutment portion for the fastening assembly 14 to abut against.

[0127] The adjusting member 13 has a contact surface 131, which is formed on the inner surface of the adjusting member 13, that is, the inner surface of the adjusting member 13 includes the contact surface 131. For example, in Figure 8, the contact surface 131 is an arc surface formed on the inner surface of the adjusting member 13. Of course, in other embodiments, the contact surface 131 can also be an inclined plane set on the adjusting member 13.

[0128] It should be noted that in other embodiments, the locking mechanism 10 may also have other structures. For example, part of the adjusting member 13 is inserted into the locking member 12 , and correspondingly, the abutting surface 131 is formed on the outer surface of the adjusting member 13 .

[0129] The fastening component 14 is arranged on the locking member 12, and the adjusting member 13 has an abutting surface 131 that abuts against the fastening component 14, so that when the locking member 12 is in a locked state, the fastening component 14 can abut against the abutting surface 131 in the first direction X along the direction of the adjusting member 13 pointing to the lock seat 300, so as to prevent the locking member 12 from moving relative to the adjusting member 13 in the first direction X along the direction of the adjusting member 13 pointing to the lock seat 300, thereby transferring the force of the threaded structure between the locking member 12 and the adjusting member 13 to the abutting surface 131 between the fastening component 14 and the adjusting member 13, so as to alleviate the phenomenon of slipping or damage to the threaded structure between the locking member 12 and the adjusting member 13.

[0130] According to some embodiments of the present application, as shown in Figures 6, 7, and 8, the locking member 12 includes a mounting portion 123 inserted into the adjusting member 13 along the first direction X. The inner surface of the adjusting member 13 includes an abutment surface 131. The fastening assembly 14 includes a clamping member 141, which is movably disposed on the mounting portion 123. The clamping member 141 is configured to abut against the abutment surface 131 after protruding from the outer peripheral surface of the mounting portion 123, or to release the abutment from the abutment surface 131 after retracting into the mounting portion 123.

[0131] The inner surface of the adjusting member 13 includes a contact surface 131 , that is, the contact surface 131 is formed on the inner surface of the adjusting member 13 .

[0132] The clip 141 serves to prevent the locking member 12 from moving relative to the adjusting member 13 in the first direction X along the direction of the adjusting member 13 pointing to the lock seat 300 after abutting against the abutting surface 131. The clip 141 is movably arranged on the mounting portion 123. The clip 141 is used to abut against the abutting surface 131 after protruding from the outer peripheral surface of the mounting portion 123 or to release the abutment from the abutment surface 131 after retracting into the mounting portion 123. That is, the clip 141 can abut against the abutting surface 131 of the adjusting member 13 when it moves relative to the mounting portion 123 and protrudes from the outer peripheral surface of the mounting portion 123, so as to prevent the locking member 12 from moving relative to the adjusting member 13. Conversely, when the clip 141 moves relative to the mounting portion 123 and retracts into the mounting portion 123, it can release the abutment from the abutting surface 131 of the adjusting member 13 to allow the locking member 12 to move relative to the adjusting member 13.

[0133] For example, in Figure 8, a mounting hole 1231 is provided on the outer peripheral surface of the mounting portion 123, and the clamping member 141 is movably provided in the mounting hole 1231 along the radial direction of the mounting portion 123, so that the clamping member 141 can protrude from the outer peripheral surface of the mounting portion 123 or retract into the mounting portion 123 when it moves relative to the mounting portion 123 along the radial direction of the mounting portion 123.

[0134] It should be noted that in other embodiments, the structure of the fastening component 14 can be various. For example, the fastening component 14 can be a locking pin inserted between the locking member 12 and the adjusting member 13. When the locking member 12 is in a locked state, the locking pin is inserted between the locking member 12 and the adjusting member 13 along the radial direction of the locking member 12 to prevent the locking member 12 from moving relative to the adjusting member 13 in the first direction X along the direction of the adjusting member 13 pointing to the lock seat 300.

[0135] The locking member 12 has a mounting portion 123 inserted into the interior of the adjusting member 13, and the abutment surface 131 is located on the inner surface of the adjusting member 13, so that the clamping member 141 of the fastening assembly 14 can abut against the abutment surface 131 after protruding from the outer peripheral surface of the mounting portion 123, so that the fastening assembly 14 prevents the locking member 12 from moving relative to the adjusting member 13 in the first direction X along the direction of the adjusting member 13 pointing to the lock seat 300. Conversely, the clamping member 141 of the fastening assembly 14 can release the abutment from the abutment surface 131 after retreating into the mounting portion 123, thereby enabling the locking member 12 to move relative to the adjusting member 13. The structure is simple and easy to implement.

[0136] According to some embodiments of the present application, with reference to Figures 6, 7, and 8, and further with reference to Figure 9, which is a cross-sectional view of the locking mechanism 10 (when the locking member 12 is in an unlocked state) provided in some embodiments of the present application. The fastening assembly 14 may further include a moving member 142, which is movably disposed in the mounting portion 123 along the first direction X. The moving member 142 is configured to push the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123 or allow the clamping member 141 to retract into the mounting portion 123 when moving relative to the mounting portion 123 along the first direction X, so that the clamping member 141 abuts against or releases the abutment with the abutment surface 131.

[0137] Among them, the moving member 142 plays the role of pushing the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123 or allowing the clamping member 141 to retreat into the mounting portion 123. It should be noted that, referring to Figure 8, when the moving member 142 moves along the first direction X toward the direction close to the connecting portion 121 of the locking member 12, the moving member 142 can push the clamping member 141 to move relative to the mounting portion 123 along the radial direction of the mounting portion 123 and protrude from the outer peripheral surface of the mounting portion 123, so as to achieve The clamping member 141 can abut against the abutting surface 131 and lock the clamping member 141 in a position abutting against the abutting surface 131. When the moving member 142 moves along the first direction X in a direction away from the connecting portion 121 of the locking member 12, the moving member 142 can release the constraint on the clamping member 141, so that the clamping member 141 can retreat into the mounting portion 123 under the reaction force of the abutting surface 131, so that the clamping member 141 can be released from the abutment with the abutting surface 131.

[0138] The fastening assembly 14 is also provided with a movable member 142 for pushing the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123 and allowing the clamping member 141 to retreat into the mounting portion 123. By movably arranging the movable member 142 in the mounting portion 123 along the first direction X, the movable member 142 can push the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123 and prevent the clamping member 141 from retreating when it moves relative to the mounting portion 123 in one direction of the first direction X, and can release the abutment against the clamping member 141 when it moves relative to the mounting portion 123 in the other direction of the first direction X, so as to allow the clamping member 141 to retreat into the mounting portion 123, thereby realizing that the clamping member 141 can abut or release the abutment with the abutment surface 131.

[0139] According to some embodiments of the present application, as shown in Figures 6, 7, 8 and 9, the adjusting member 13 is configured to drive the locking member 12 to move between a first position and a second position along a first direction X when rotating relative to the sleeve 11. When the locking member 12 is in the first position (as shown in Figure 7), the locking member 12 is in a locked state. When the locking member 12 is in the second position (as shown in Figure 9), the locking member 12 is in an unlocked state. The adjusting member 13 is provided with an execution portion 132. The execution portion 132 is configured to: when the locking member 12 moves from the second position to the first position, it can abut against the moving member 142 and push the moving member 142 to move, so that the moving member 142 can push the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123; when the locking member 12 moves from the first position to the second position, it can separate from the moving member 142, so that the moving member 142 can allow the clamping member 141 to retreat into the mounting portion 123.

[0140] 7 , so that the clamping member 141 can be released from the abutment surface 131.

[0141] For example, referring to Figures 6 and 8, an installation channel 133 is provided at one end of the adjusting member 13 away from the clamping portion 122 of the locking member 12, and the executing portion 132 is accommodated in the installation channel 133 and fixedly connected to the adjusting member 13. Correspondingly, an accommodating cavity 1232 is provided inside the mounting portion 123, and the accommodating cavity 1232 passes through the end of the mounting portion 123 away from the clamping portion 122 in the first direction X, so that the accommodating cavity 1232 is communicated with the installation channel 133, and the accommodating cavity 1232 is communicated with the mounting hole 1231 provided on the outer peripheral surface of the mounting portion 123, and the moving member 142 is movably provided in the accommodating cavity 1232 along the first direction X. The executing portion 132 and the locking member 12 are arranged along the first direction X, so that the locking member 12 moves from the second position to the first position When the locking member 12 is moved in the first direction X toward the executing portion 132, part of the executing portion 132 can be inserted into the accommodating cavity 1232 and abut against the moving member 142 (as shown in FIG7 ), so as to push the moving member 142 to move in the first direction X toward the connecting portion 121. Conversely, when the locking member 12 is moved from the first position to the second position, that is, when the locking member 12 is moved in the first direction X away from the executing portion 132, the executing portion 132 can exit the accommodating cavity 1232 and separate from the moving member 142 (as shown in FIG9 ), so that the moving member 142 can move in the first direction X away from the connecting portion 121, thereby realizing that the engaging member 141 can abut or release the abutment with the abutting surface 131 through the executing portion 132.

[0142] Optionally, the execution part 132 can be connected to the adjustment part 13 in various ways. For example, the execution part 132 can be screwed into the adjustment part 13, welded into the adjustment part 13, or connected to the inner wall surface of the installation channel 133 by interference fit.

[0143] The adjusting member 13 can drive the locking member 12 to switch between the locked state and the unlocked state while also driving the locking member 12 to move relative to the sleeve 11 along the first direction X, so that the locking member 12 has a first position and a second position in the first direction X. By providing an execution portion 132 on the adjusting member 13, the execution portion 132 can abut against the moving member 142 and push the moving member 142 to move when the locking member 12 moves from the second position to the first position, so that the clamping member 141 can protrude from the outer peripheral surface of the mounting portion 123 under the push of the moving member 142, and the execution portion 132 can also abut against the moving member 142 when the locking member 12 moves from the first position to the second position. 42 is separated to release the constraint of the execution part 132 on the moving part 142, so that the moving part 142 can allow the clamping part 141 to retreat into the installation part 123, so that the locking part 12 is switched between the locked state and the unlocked state by moving the locking part 12 along the first direction X, and the clamping part 141 of the fastening assembly 14 can be protruded from the outer peripheral surface of the installation part 123 or allowed to retreat into the installation part 123 under the cooperation of the moving part 142 and the execution part 132, so as to realize the linkage of the locking mechanism 10, without the need for additional driving mechanism or manual participation, which is conducive to reducing the operation difficulty of the locking mechanism 10.

[0144] According to some embodiments of the present application, as shown in Figures 8 and 9, the execution part 132 and the mounting part 123 are arranged along the first direction X, and a protrusion 1321 is provided at one end of the execution part 132 facing the mounting part 123, and the protrusion 1321 is configured to be inserted into the mounting part 123 and abut against the moving part 142.

[0145] Among them, along the first direction X, the protrusion 1321 is protruded from one end of the execution part 132 facing the locking member 12, and the protrusion 1321 can be inserted into the accommodating cavity 1232 and abut against the moving member 142, so that the execution part 132 pushes the moving member 142 to move.

[0146] By providing a protrusion 1321 at one end of the executing portion 132 facing the mounting portion 123 along the first direction X, the protrusion 1321 can be inserted into the mounting portion 123 and abut against the moving member 142 when the mounting portion 123 approaches the executing portion 132 along the first direction X, thereby facilitating improving the effect of the executing portion 132 in pushing the moving member 142 to move.

[0147] In some embodiments, as shown in FIG8 , a receiving cavity 1232 is formed within the mounting portion 123. The receiving cavity 1232 extends through one end of the mounting portion 123 near the actuator 132 along the first direction X. The convex portion 1321 is inserted into the receiving cavity 1232. The movable member 142 is movably disposed within the receiving cavity 1232 along the first direction X. A mounting hole 1231 is disposed on the outer circumference of the mounting portion 123. The mounting hole 1231 communicates with the receiving cavity 1232. The engaging member 141 is movably disposed within the mounting hole 1231.

[0148] By providing an accommodating cavity 1232 for accommodating the movable member 142 within the mounting portion 123, and the accommodating cavity 1232 extending through one end of the mounting portion 123 along the first direction X, the protrusion 1321 of the actuator 132 can be inserted into the accommodating cavity 1232, thereby enabling the protrusion 1321 and the movable member 142 to abut against each other, which helps to simplify the structural complexity of the locking mechanism 10. In addition, by providing a mounting hole 1231 on the outer peripheral surface of the mounting portion 123 that communicates with the accommodating cavity 1232, and by movably disposing the clamping member 141 within the mounting hole 1231, when the movable member 142 moves within the accommodating cavity 1232 along the first direction X, the clamping member 141 can be pushed to protrude from the outer peripheral surface of the mounting portion 123 through the mounting hole 1231, or the third clamping portion 122 can be allowed to retract into the mounting portion 123 through the mounting hole 1231, resulting in a simple structure and easy implementation.

[0149] According to some embodiments of the present application, as shown in Figure 8, the fastening assembly 14 may further include a first elastic member 143, which is arranged between the movable member 142 and the mounting portion 123, and the first elastic member 143 is configured to drive the movable member 142 to move along the first direction X toward the direction close to the execution portion 132, so that the movable member 142 can allow the clamping member 141 to retreat into the mounting portion 123.

[0150] The first elastic member 143 is configured to drive the moving member 142 to move along the first direction X toward the actuator 132 . That is, the first elastic member 143 can apply an elastic force in the first direction X toward the actuator 132 to the moving member 142 .

[0151] For example, in Figure 8, the first elastic member 143 is connected in a compressed state in the first direction X between the movable member 142 and the bottom surface of the accommodating cavity 1232. Of course, in other embodiments, the first elastic member 143 can also be connected in a stretched state along the first direction X between the movable member 142 and the end of the mounting portion 123 away from the connecting portion 121.

[0152] For example, in FIG. 8 , the first elastic member 143 is a spring. In other embodiments, the first elastic member 143 may also be a spring or elastic rubber disposed between the moving member 142 and the mounting portion 123 .

[0153] A first elastic member 143 is further provided between the movable member 142 and the mounting portion 123. The first elastic member 143 can apply a force to the movable member 142 along the first direction X toward the execution portion 132, so that the movable member 142 can automatically reset to a position allowing the clamping member 141 to retreat into the mounting portion 123 after being separated from the execution portion 132. On the one hand, this can alleviate the phenomenon of the clamping member 141 and the abutting surface 131 of the adjusting member 13 being mistakenly abutted due to the inability of the movable member 142 to reset. On the other hand, it does not require manual labor and is easy to operate and use.

[0154] According to some embodiments of the present application, as shown in Figures 6 and 8, a first limiting portion 1233 is provided inside the mounting portion 123, and a second limiting portion 1421 is provided on the movable member 142. The first limiting portion 1233 and the second limiting portion 1421 cooperate to limit the range of movement of the movable member 142 in the first direction X relative to the mounting portion 123.

[0155] Among them, the first limiting portion 1233 and the second limiting portion 1421 are respectively arranged on the mounting portion 123 and the movable member 142, so that the first limiting portion 1233 and the second limiting portion 1421 play a role in cooperating to limit the moving range of the movable member 142 in the first direction X. The structures of the first limiting portion 1233 and the second limiting portion 1421 can be various. For example, the first limiting portion 1233 can be a limiting block arranged on the inner surface of the mounting portion 123, and correspondingly, the second limiting portion 1421 is a groove arranged on the outer peripheral surface of the movable member 142, and at least part of the limiting block is inserted into the groove. Of course, the first limiting portion 1233 can also be a strip hole arranged on the inner surface of the mounting portion 123, and the length direction of the strip hole is the first direction X. Correspondingly, the second limiting portion 1421 is a pin protruding from the outer peripheral surface of the mounting portion 123, and at least part of the pin is inserted into the strip hole.

[0156] The mounting portion 123 and the movable member 142 are respectively provided with a first limiting portion 1233 and a second limiting portion 1421. Through the cooperation of the first limiting portion 1233 and the second limiting portion 1421, the movement range of the movable member 142 relative to the mounting portion 123 in the first direction X can be limited. On the one hand, the movable member 142 can be accurately switched along the first direction X between a position of pushing the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123 and a position of allowing the clamping member 141 to retreat into the mounting portion 123, which is beneficial to improving the accuracy of the abutment and release of the abutment between the clamping member 141 and the abutment surface 131. On the other hand, it can play a certain limiting role on the movable member 142 to reduce the risk of the movable member 142 detaching from the mounting portion 123.

[0157] In some embodiments, referring to FIG8 and further to FIG10 , FIG10 is a cross-sectional view of the movable member 142 of the fastening assembly 14 of the locking mechanism 10 provided in some embodiments of the present application. The first limiting portion 1233 is a limiting block provided on the inner circumference of the mounting portion 123, and the second limiting portion 1421 is a groove provided on the outer circumference of the movable member 142, with at least a portion of the limiting block being accommodated in the groove.

[0158] Wherein, at least a portion of the limiting block is accommodated in the groove, that is, the limiting block may be entirely accommodated in the groove, or may be only partially accommodated in the groove.

[0159] Exemplarily, the limit block is snapped into the mounting groove on the inner circumference of the mounting portion 123. Of course, in other embodiments, the limit block can also be connected to the inner circumference of the mounting portion 123 by welding, bonding or interference fit.

[0160] In other embodiments, the groove may also be provided on the inner circumference of the mounting portion 123 , and correspondingly, the limiting block may be protruded on the outer circumference of the moving member 142 .

[0161] It should be noted that in the embodiment where a first elastic member 143 is provided between the movable member 142 and the mounting portion 123 , the first elastic member 143 may also be provided between the side of the limit block facing the connecting portion 121 in the first direction X and the side wall of the groove.

[0162] The first limiting portion 1233 and the second limiting portion 1421 are respectively a limiting block arranged on the inner circumferential surface of the mounting portion 123 and a groove on the outer circumferential surface of the movable member 142. By inserting the limiting block into the groove, when the movable member 142 moves relative to the mounting portion 123, the limiting block can abut against the two opposite side walls of the groove in the first direction X, so as to limit the moving range of the movable member 142 in the first direction X under the cooperation of the limiting block and the groove. The structure is simple, easy to implement, and has high stability.

[0163] In some embodiments, referring to FIG. 6 , FIG. 8 and FIG. 10 , the first limiting portion 1233 is an annular limiting block extending along the circumference of the moving member 142 , and the second limiting portion 1421 is an annular groove extending along the circumference of the moving member 142 .

[0164] By configuring the first limiting portion 1233 and the second limiting portion 1421 to be annular structures, the stability and reliability of the first limiting portion 1233 and the second limiting portion 1421 cooperating with the limiting moving member 142 can be further improved.

[0165] According to some embodiments of the present application, as shown in Figures 8 and 10, a guiding slope 1422 is formed on the moving member 142, and the guiding slope 1422 is used to abut against the clamping member 141 to push the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123.

[0166] Among them, the guiding inclined surface 1422 is formed at one end of the moving member 142 close to the connecting portion 121 in the first direction X. For example, the end of the moving member 142 close to the connecting portion 121 in the first direction X is a conical structure, so that a conical surface is formed at one end of the moving member 142 close to the connecting portion 121 in the first direction X, and the conical surface is the guiding inclined surface 1422, so that when the moving member 142 moves along the first direction X toward the connecting portion 121, the clamping member 141 can protrude from the outer peripheral surface of the mounting portion 123 under the push of the guiding inclined surface 1422.

[0167] By providing a guiding slope 1422 on the moving part 142 for the clamping part 141 to abut, the clamping part 141 can protrude from the outer peripheral surface of the mounting part 123 under the guidance of the guiding slope 1422 when the moving part 142 moves along the first direction X, so that the moving part 142 can drive the clamping part 141 to protrude from the outer peripheral surface of the mounting part 123 or allow the clamping part 141 to retreat into the mounting part 123, so that the locking mechanism 10 adopting this structure can reduce the phenomenon of mutual jamming between the moving part 142 and the clamping part 141.

[0168] According to some embodiments of the present application, as shown in FIG. 6 and FIG. 8 , the fastening assembly 14 includes a plurality of clips 141 , and the plurality of clips 141 are arranged at intervals along the circumference of the mounting portion 123 .

[0169] Exemplarily, the fastening assembly 14 is provided with four clamping members 141, and the four clamping members 141 are spaced and evenly arranged around the moving member 142. Of course, in other embodiments, the number of the clamping members 141 can also be two, three, five or six.

[0170] The fastening assembly 14 is provided with a plurality of clips 141, and the plurality of clips 141 are arranged at intervals along the circumference of the mounting portion 123, that is, when the plurality of clips 141 all protrude from the outer peripheral surface of the mounting portion 123, the plurality of clips 141 are a structure arranged around the mounting portion 123, thereby further improving the structural stability and reliability of the mutual abutment between the fastening assembly 14 and the adjusting member 13, which is beneficial to improving the effect of the fastening assembly 14 sharing the force of the threaded structure between the locking member 12 and the adjusting member 13.

[0171] In some embodiments, as shown in Figures 6 and 8, the clamping member 141 is spherical. Of course, in other embodiments, the clamping member 141 can also be a cube structure, a rectangular parallelepiped structure, or a cone structure.

[0172] By setting the clamping member 141 as a spherical structure, it is convenient for the movable member 142 to push the clamping member 141 to protrude from the outer peripheral surface of the mounting portion 123 or allow the clamping member 141 to retract into the mounting portion 123 when moving relative to the mounting portion 123 along the first direction X, thereby reducing the phenomenon of mutual jamming between the movable member 142 and the clamping member 141.

[0173] According to some embodiments of the present application, as shown in Figures 5, 6, 7, and 8, the locking member 12 includes a connecting portion 121 and a clamping portion 122. The connecting portion 121 extends along a first direction X and is inserted into the sleeve 11. The connecting portion 121 is threadedly connected to the adjusting member 13. The clamping portion 122 is located outside the sleeve 11 and is connected to the end of the connecting portion 121 away from the sleeve 11. The clamping portion 122 protrudes from the outer circumference of the connecting portion 121 along its extension direction. The clamping portion 122 is configured to engage with the lock base 300. The extension direction of the clamping portion 122 is perpendicular to the first direction X. The adjusting member 13 can rotate relative to the sleeve 11 to drive the connecting portion 121 to rotate, thereby engaging or disengaging the clamping portion 122 with the lock base 300, thereby switching the locking member 12 between a locked state and an unlocked state.

[0174] The mounting portion 123 is connected to one end of the connecting portion 121 in the first direction X, away from the engaging portion 122. The connecting portion 121 of the locking member 12 is a cylindrical structure extending in the first direction X. A portion of the connecting portion 121 is inserted into the sleeve 11 along the first direction X. The portion of the connecting portion 121 inserted into the sleeve 11 is threadedly connected to the adjusting member 13. For example, the portion of the adjusting member 13 is sleeved outside the connecting portion 121, and the adjusting member 13 has an internal thread. Correspondingly, the portion of the connecting portion 121 received within the adjusting member 13 has an external thread, so that the connecting portion 121 and the adjusting member 13 are threadedly connected, allowing the adjusting member 13 to drive the connecting portion 121 to rotate about an axis extending in the first direction X. Of course, in other embodiments, a portion of the connecting portion 121 may be sleeved outside the adjusting member 13, and the connecting portion 121 has an internal thread. Correspondingly, the portion of the adjusting member 13 received within the connecting portion 121 has an external thread, so that the connecting portion 121 and the adjusting member 13 are threadedly connected.

[0175] The clamping portion 122 is located outside the sleeve 11 and is connected to one end of the connecting portion 121 away from the sleeve 11, that is, the connecting portion 121 has a portion that is not inserted into the sleeve 11, and the clamping portion 122 is connected to one end of the portion of the connecting portion 121 that is not inserted into the sleeve 11, so that the clamping portion 122 is arranged at intervals from the sleeve 11 along the first direction X.

[0176] The clamping portion 122 protrudes from the outer peripheral surface of the connecting portion 121 along its extension direction, that is, in the extension direction of the clamping portion 122, the clamping portion 122 extends beyond the outer peripheral surface of the connecting portion 121. For example, in Figures 6 and 7, the extension direction of the clamping portion 122 is perpendicular to the first direction X, so that the clamping portion 122 and the connecting portion 121 form a "T"-shaped structure. Of course, in other embodiments, the clamping portion 122 and the connecting portion 121 can also form an "L"-shaped structure.

[0177] The adjusting member 13 can drive the connecting portion 121 to rotate by rotating relative to the sleeve 11, so that the clamping portion 122 is clamped or released from the lock seat 300, so that the locking member 12 is switched between the locked state and the unlocked state, that is, when the adjusting member 13 rotates relative to the sleeve 11, it can drive the clamping portion 122 to rotate around the axis extending along the first direction X through the connecting portion 121, thereby changing the extension direction of the clamping portion 122, so that the clamping portion 122 can overlap the lock seat 300 or release the overlap from the lock seat 300, so that the clamping portion 122 can be clamped or released from the lock seat 300.

[0178] In some embodiments, refer to FIG. 7 and further refer to FIG. 11 , which is a schematic diagram of the connection between the locking mechanism 10 and the lock base 300 provided in some embodiments of the present application. When the locking mechanism 10 and the lock base 300 are in engagement with each other, the locking mechanism 10 and the lock base 300 are locked.

[0179] Among them, the cross-section of the locking hole 310 is rectangular. When the extension direction of the clamping portion 122 is consistent with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be inserted into the locking hole 310 or can be withdrawn from the locking hole 310. When the clamping portion 122 passes through the locking hole 310 and the extension direction of the clamping portion 122 intersects with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be engaged with the surface of the lock seat 300 on the side facing away from the sleeve 11.

[0180] Optionally, a card slot 320 is further provided on the surface of the lock seat 300 for the engaging portion 122, and the extending direction of the card slot 320 is perpendicular to the length direction of the cross section of the lock hole 310. When the card slot 122 is rotated so that the extending direction is perpendicular to the length direction of the cross section of the lock hole 310, the card slot 320 can engage with the lock seat 300, and the card slot 320 can be inserted into the card slot 122 to alleviate the shaking phenomenon between the locking mechanism 10 and the lock seat 300, thereby helping to improve the stability of the mutual locking of the locking mechanism 10 and the lock seat 300.

[0181] In some embodiments, as shown in FIG7 , a clamping surface 111 is further formed at one end of the sleeve 11 near the clamping portion 122 along the first direction X. The clamping surface 111 is configured to abut against a side of the lock base 300 facing the sleeve 11 when the locking member 12 is in the locked state. When the locking mechanism 10 is engaged with the lock base 300 along the first direction X, the clamping portion 122 and the clamping surface 111 respectively abut against two sides of the lock base 300 in the first direction X. By setting the clamping surface 111 of the sleeve 11 so that it can abut against the side of the lock seat 300 facing the sleeve 11 when the locking member 12 and the lock seat 300 are clamped in the locked state, the locking mechanism 10 can clamp the lock seat 300 in the first direction X through the clamping portion 122 of the locking member 12 and the clamping surface 111 of the sleeve 11, which is beneficial to reduce the shaking phenomenon of the locking mechanism 10 during use, thereby improving the stability of the mutual locking between the locking mechanism 10 and the lock seat 300.

[0182] The locking member 12 is provided with a connecting portion 121 and a clamping portion 122 connected to one end of the connecting portion 121, and the clamping portion 122 protrudes from the outer peripheral surface of the connecting portion 121 in its extension direction. By inserting the connecting portion 121 into the sleeve 11 along the first direction X and threadedly connected to the adjusting member 13, the adjusting member 13 can drive the connecting portion 121 to rotate when rotating, so that the clamping portion 122 can rotate with the connecting portion 121, thereby changing the extension direction of the clamping portion 122 in a plane perpendicular to the first direction X, so that the clamping portion 122 can be clamped or released with the lock seat 300 after rotation, thereby realizing that the locking mechanism 10 can engage with or disengage from the lock seat 300 in the first direction X.

[0183] According to some embodiments of the present application, as shown in Figures 6 and 7, the sleeve 11 is provided with a third limiting portion 112, and the connecting portion 121 is provided with a fourth limiting portion 1211. The third limiting portion 112 and the fourth limiting portion 1211 cooperate to limit the rotation angle of the connecting portion 121.

[0184] Among them, the third limiting portion 112 and the fourth limiting portion 1211 play the role of cooperating to limit the rotation angle of the connecting portion 121 relative to the sleeve 11. The structures of the third limiting portion 112 and the fourth limiting portion 1211 can be various. For example, the third limiting portion 112 can be a limiting groove provided on the inner circumference of the sleeve 11, and correspondingly, the fourth limiting portion 1211 can be a protrusion convexly provided on the outer circumference of the connecting portion 121, and the protrusion is inserted into the limiting groove to cooperate with the rotation of the connecting portion 121. To limit the moving angle, of course, the third limiting portion 112 and the fourth limiting portion 1211 can also be protrusions, the third limiting portion 112 is protruded at one end of the sleeve 11 in the first direction X, and the fourth limiting portion 1211 is protruded on the outer peripheral surface of the connecting portion 121. The fourth limiting portion 1211 can abut against the third limiting portion 112 when the connecting portion 121 rotates relative to the sleeve 11, so as to limit the rotation angle of the connecting portion 121 through the mutual cooperation of the third limiting portion 112 and the fourth limiting portion 1211.

[0185] Optionally, the number of the third limiting portion 112 and the fourth limiting portion 1211 can be one or more. For example, in an embodiment of the present application, there are two third limiting portions 112, and correspondingly, there are also two fourth limiting portions 1211. The two fourth limiting portions 1211 are respectively arranged on both sides of the connecting portion 121 along the radial direction of the connecting portion 121.

[0186] By respectively arranging the third limiting portion 112 and the fourth limiting portion 1211 on the sleeve 11 and the connecting portion 121, the third limiting portion 112 and the fourth limiting portion 1211 can cooperate to limit the rotation angle of the connecting portion 121, so that the connecting portion 121 drives the clamping portion 122 to be clamped or released with the lock seat 300 under the cooperation restriction of the third limiting portion 112 and the fourth limiting portion 1211, thereby facilitating the switching of the locking member 12 between the locked state and the unlocked state. The structure is simple and easy to operate, and can alleviate the phenomenon that the clamping portion 122 cannot be clamped with the lock seat 300 due to the excessive rotation angle of the clamping portion 122 following the connecting portion 121, which is beneficial to improving the reliability of the mutual locking between the locking mechanism 10 and the lock seat 300.

[0187] According to some embodiments of the present application, as shown in Figures 7 and 9, the third limiting portion 112 and the fourth limiting portion 1211 are further configured to cooperate with the guiding connecting portion 121 to move along the first direction X when the adjusting member 13 rotates relative to the sleeve 11, so as to move the locking member 12 between the first position and the second position along the first direction X. When the locking member 12 is in the first position, the locking member 12 is in a locked state, so that the engaging portion 122 can engage with the lock base 300. When the locking member 12 is in the second position, the locking member 12 is in an unlocked state, so that the engaging portion 122 can be released from the lock base 300.

[0188] Among them, the third limiting portion 112 and the fourth limiting portion 1211 are further configured to cooperate to guide the connecting portion 121 to move along the first direction X when the adjusting member 13 rotates relative to the sleeve 11, that is, in the process of the adjusting member 13 driving the connecting portion 121 to rotate relative to the sleeve 11, the third limiting portion 112 and the fourth limiting portion 1211 cooperate to limit the rotation angle of the connecting portion 121 while also guiding the connecting portion 121 to move relative to the sleeve 11 in the first direction X, so that the locking member 12 has two end positions relative to the sleeve 11 in the first direction X, namely the first position and the second position. That is to say, when the adjusting member 13 drives the connecting portion 121 to rotate relative to the sleeve 11, the connecting portion 121 can also move relative to the sleeve 11 along the first direction X, so that when the connecting portion 121 drives the clamping portion 122 to rotate until the clamping portion 122 can engage with the side of the lock seat 300 away from the sleeve 11, the locking member 12 is in the first position. Correspondingly, when the locking member 12 moves to the second position, the projection of the clamping portion 122 in the first direction X is located within the lock hole 310 of the lock seat 300, so that the locking member 12 can be disengaged from the lock seat 300 along the first direction X.

[0189] When the adjusting member 13 rotates relative to the sleeve 11, it can not only drive the connecting part 121 to rotate, but also drive the connecting part 121 to move along the first direction X. For example, in Figure 7, the adjusting member 13 and the connecting part 121 are connected by a threaded structure, so that the adjusting member 13 can drive the connecting part 121 to rotate, and when the circumferential rotation of the connecting part 121 is restricted, the adjusting member 13 can provide the connecting part 121 with a feed force along the first direction X, so that the connecting part 121 can move along the first direction X.

[0190] The third limiting portion 112 and the fourth limiting portion 1211 can cooperate to guide the connecting portion 121 to move relative to the sleeve 11 in the first direction X while limiting the rotation angle of the connecting portion 121, so that the adjusting member 13 can drive the connecting portion 121 to rotate relative to the sleeve 11 while also driving the locking member 12 to move between the first position and the second position along the first direction X, so that the adjusting member 13 can drive the clamping portion 122 to clamp with the lock base 300 while also driving the clamping portion 122 and the lock base 300 to abut against each other, so as to reduce the size of the gap between the clamping portion 122 and the lock base 300, thereby reducing the vibration between the locking mechanism 10 and the lock base 300.

[0191] According to some embodiments of the present application, referring to Figures 6 and 7, the third limiting portion 112 is a limiting groove provided on the inner circumferential surface of the sleeve 11, and the fourth limiting portion 1211 is a protrusion provided on the outer circumferential surface of the connecting portion 121, and at least a portion of the protrusion is accommodated in the limiting groove.

[0192] Among them, the third limiting portion 112 is a limiting groove, and the fourth limiting portion 1211 is a protrusion. By inserting the protrusion into the limiting groove, the movement trajectory of the protrusion will be restricted and guided by the limiting groove, so that the connecting portion 121 can limit the rotation angle and move between the first position and the second position along the first direction X under the cooperation of the third limiting portion 112 and the fourth limiting portion 1211.

[0193] It should be noted that, in other embodiments, the third limiting portion 112 and the fourth limiting portion 1211 can also be other structures. For example, the third limiting portion 112 is a protrusion protruding from the inner circumference of the sleeve 11, and correspondingly, the fourth limiting portion 1211 is a limiting groove provided on the outer circumference of the connecting portion 121.

[0194] The third limiting portion 112 and the fourth limiting portion 1211 are respectively a limiting groove arranged on the inner circumference of the sleeve 11 and a protrusion on the outer circumference of the connecting portion 121. By inserting the protrusion into the limiting groove, the rotation angle of the connecting portion 121 is limited under the restriction of the limiting groove, and the protrusion can be guided by the limiting groove to enable the connecting portion 121 to rotate relative to the sleeve 11 while moving along the first direction X relative to the sleeve 11. The structure is simple, easy to implement, and has high stability.

[0195] In some embodiments, referring to FIG. 7 and further to FIG. 12 , FIG. 12 is a cross-sectional view of the sleeve 11 of the locking mechanism 10 provided in some embodiments of the present application. The limiting groove includes a first groove section 1121, a second groove section 1122, and a third groove section 1123, which are sequentially connected. The first groove section 1121 and the third groove section 1123 both extend along the first direction X. The first groove section 1121 and the third groove section 1123 are spaced apart along the circumference of the connecting portion 121, and the first groove section 1121 and the third groove section 1123 are spaced apart along the first direction X. Along the first direction X, the third groove section 1123 is closer to the engaging portion 122 than the first groove section 1121. When the locking member 12 is in the first position, the protrusion is located in the first groove section 1121. When the locking member 12 is in the second position, the protrusion is located in the third groove section 1123.

[0196] Among them, the first slot segment 1121 and the third slot segment 1123 are arranged at intervals along the circumference of the connecting portion 121, and the first slot segment 1121 and the third slot segment 1123 are arranged at intervals along the first direction X, that is, there is a distance between the first slot segment 1121 and the third slot segment 1123 of the limiting slot in the first direction X, and there is also a distance in the circumferential direction of the connecting portion 121. It should be noted that, since the first groove segment 1121 and the third groove segment 1123 are arranged at intervals in the first direction X and in the circumferential direction of the connecting portion 121, the second groove segment 1122 connecting the first groove segment 1121 and the third groove segment 1123 is a spiral structure surrounding the connecting portion 121, so that when the protrusion is located in the first groove segment 1121 and the third groove segment 1123, the connecting portion 121 can only move along the first direction X under the drive of the adjustment member 13, and when the protrusion is located in the second groove segment 1122, the connecting portion 121 can be driven by the adjustment member 13 to move along the first direction X and rotate around the axis extending along the first direction X.

[0197] When the locking member 12 is in the first position, the protrusion is located in the first groove section 1121, and when the locking member 12 is in the second position, the protrusion is located in the third groove section 1123. That is, when the protrusion of the connecting portion 121 moves from the first groove section 1121 to the third groove section 1123, the locking member 12 can move from the first position to the second position.

[0198] Of course, the structure of the limiting groove is not limited to this. In some embodiments, the limiting groove may also be other structures. For example, the limiting groove extends along the first direction X and has a wider width in the circumferential direction of the connecting portion 121, so that the limiting groove has two opposite groove side walls in the circumferential direction of the connecting portion 121. The two groove side walls are arranged at intervals in the circumferential direction of the connecting portion 121, and the two groove side walls are both used for the protrusion to abut. The protrusion is inserted into the limiting groove, and the protrusion can move between the two groove side walls along the circumference of the connecting portion 121 to limit the rotation angle of the connecting portion 121. When the protrusion abuts against the groove side walls of the limiting groove, the groove side walls of the limiting groove can block the rotation of the connecting portion 121 to limit the rotation angle of the connecting portion 121. After being blocked by the groove side walls of the limiting groove, the protrusion of the connecting portion 121 can move along the first direction X under the guidance of the groove side walls of the limiting groove, so that the connecting portion 121 can move along the first direction X.

[0199] By setting the first groove section 1121 and the third groove section 1123 of the limiting groove to be structures that both extend along the first direction X, and the first groove section 1121 and the third groove section 1123 are arranged at intervals in the first direction X and the circumferential direction of the connecting portion 121, so that the second groove section 1122 is a spiral groove connected between the first groove section 1121 and the third groove section 1123, so that when the protrusion of the connecting portion 121 is located in the first groove section 1121 and the third groove section 1123, it can only move along the first direction X following the extension direction of the first groove section 1121 and the second groove section 1122, and when the protrusion of the connecting portion 121 is located in the second groove section 1122, it can follow the extension direction of the second groove section 1122 and can both rotate relative to the sleeve 11 and move relative to the sleeve 11 along the first direction X, thereby achieving the limitation of the rotation angle of the locking member 12 and enabling movement between the first position and the second position along the first direction X. In addition, by setting the third groove section 1123 to be closer to the clamping portion 122 than the first groove section 1121 in the first direction X, the clamping portion 122 can be clamped with the lock seat 300 when the protrusion is located in the first groove section 1121 and can be closer to the sleeve 11, so that the clamping portion 122 can abut against the lock seat 300 in the first direction X.

[0200] According to some embodiments of the present application, as shown in Figures 6 and 7, the adjustment member 13 includes a connecting section 134 arranged in the sleeve 11, the connecting section 134 is sleeved on the outside of the connecting portion 121, and the connecting section 134 is threadedly connected to the connecting portion 121.

[0201] The connecting section 134 is sleeved on the outside of the connecting portion 121 and is threadedly connected to the connecting portion 121 to achieve a threaded connection between the locking member 12 and the adjusting member 13. That is, the connecting section 134 of the adjusting member 13 is screwed onto the outside of the connecting portion 121. In other words, the adjusting member 13 is sleeved on the outside of the connecting portion 121, and the inner circumferential surface of the adjusting member 13 is provided with an internal thread. Correspondingly, the outer circumferential surface of the connecting portion 121 is provided with an external thread, so that the connecting portion 121 and the connecting section 134 are threadedly connected. Of course, in other embodiments, the locking mechanism 10 can also be a structure in which the connecting portion 121 is screwed onto the outer side of the connecting section 134 of the adjusting member 13.

[0202] The adjusting member 13 has a connecting section 134, and the connecting section 134 is screwed to the outer side of the connecting portion 121 to realize a threaded connection between the locking member 12 and the adjusting member 13, so that the connecting portion 121 can be driven to rotate together by rotating the adjusting member 13, and the adjusting member 13 can also give the connecting portion 121 a feed force along the first direction X when the connecting portion 121 is restricted in circumferential rotation, so as to realize the movement of the connecting portion 121 in the first direction X. The structure is simple and easy to implement.

[0203] According to some embodiments of the present application, as shown in Figures 6, 7 and 8, the locking mechanism 10 may further include an anti-loosening component 15, which is arranged between the sleeve 11 and the adjusting member 13. The anti-loosening component 15 is used to selectively lock the adjusting member 13 with the sleeve 11 to limit the rotation of the adjusting member 13 relative to the sleeve 11.

[0204] Among them, the anti-loosening component 15 is used to selectively lock the adjusting part 13 and the sleeve 11 to limit the rotation of the adjusting part 13 relative to the sleeve 11, that is, the anti-loosening component 15 can selectively lock or unlock the adjusting part 13 and the sleeve 11. When the anti-loosening component 15 locks the adjusting part 13 and the sleeve 11, the adjusting part 13 cannot rotate relative to the sleeve 11. When the anti-loosening component 15 unlocks the adjusting part 13 and the sleeve 11, the adjusting part 13 can rotate relative to the sleeve 11.

[0205] The locking mechanism 10 is also provided with an anti-loosening component 15, which can selectively lock the adjusting component 13 with the sleeve 11 by arranging the anti-loosening component 15 between the sleeve 11 and the adjusting component 13, that is, when the anti-loosening component 15 releases the sleeve 11 and the adjusting component 13, the anti-loosening component 15 can allow the adjusting component 13 to rotate relative to the sleeve 11, so as to drive the locking component 12 to move relative to the sleeve 11, so that the locking component 12 and the lock seat 300 are engaged or disengaged, and when the anti-loosening component 15 locks the sleeve 11 and the adjusting component 13, the anti-loosening component 15 can limit the rotation of the adjusting component 13 relative to the sleeve 11, thereby alleviating the phenomenon of the locking failure of the locking component 12 and the lock seat 300 caused by the erroneous rotation of the adjusting component 13, so as to improve the locking effect between the locking component 12 and the lock seat 300, which is beneficial to improving the stability and reliability of the mutual locking of the locking mechanism 10 and the lock seat 300.

[0206] According to some embodiments of the present application, as shown in Figures 6, 7, and 8, the anti-loosening assembly 15 may include a first clutch member 151 and a second clutch member 152. The first clutch member 151 is disposed on the sleeve 11, and the second clutch member 152 is disposed on the adjustment member 13. The first clutch member 151 and the second clutch member 152 are configured to: restrict the adjustment member 13 from rotating relative to the sleeve 11 when engaged with each other; and allow the adjustment member 13 to rotate relative to the sleeve 11 when disengaged from each other.

[0207] The first clutch 151 and the second clutch 152 can restrict the adjustment member 13 from rotating relative to the sleeve 11 when they are engaged with each other. Conversely, when the first clutch 151 and the second clutch 152 are disengaged from each other, the adjustment member 13 can be allowed to rotate relative to the sleeve 11. Optionally, the structures of the first clutch 151 and the second clutch 152 can be various. For example, the first clutch 151 can be fixed to the inner side of the sleeve 11, and the second clutch 152 can be movably arranged on the outer side of the adjusting member 13 along the first direction X and circumferentially locked with the adjusting member 13, that is, the second clutch 152 can move relative to the adjusting member 13 along the first direction X but cannot rotate circumferentially relative to the adjusting member 13, so that when the second clutch 152 moves along the first direction X until it is engaged with the first clutch 151, the first clutch 151 and the second clutch 152 can cooperate to limit the rotation of the adjusting member 13 relative to the sleeve 11; conversely, when the first clutch 151 and the second clutch 152 are disengaged from each other, the adjusting member 13 can be allowed to rotate relative to the sleeve 11. Of course, the first clutch member 151 may also be a structure movably disposed in the sleeve 11 along the first direction X and circumferentially locked with the sleeve 11 . Correspondingly, the second clutch member 152 is fixedly sleeved on the outer side of the adjusting member 13 .

[0208] Of course, the structure of the anti-loosening component 15 is not limited to this. In other embodiments, the anti-loosening component 15 can also be other structures. For example, the anti-loosening component 15 can be a bolt threaded on the sleeve 11. When the bolt is tightened, the bolt can abut against the adjusting part 13 to limit the rotation of the adjusting part 13 relative to the sleeve 11. When the bolt is loosened, the bolt can be separated from the adjusting part 13 to allow the adjusting part 13 to rotate relative to the sleeve 11, thereby realizing that the anti-loosening component 15 can selectively lock the adjusting part 13 and the sleeve 11.

[0209] The anti-loosening assembly 15 is provided with a first clutch member 151 and a second clutch member 152 which can be engaged with and disengaged from each other, and the first clutch member 151 and the second clutch member 152 are respectively provided on the sleeve 11 and the adjusting member 13, so that the adjusting member 13 can be restricted from rotating relative to the sleeve 11 by engaging with the first clutch member 151 and the second clutch member 152, and the adjusting member 13 can be rotated relative to the sleeve 11 when the first clutch member 151 and the second clutch member 152 are disengaged from each other, so as to realize the function of the anti-loosening assembly 15 to selectively lock the adjusting member 13 and the sleeve 11.

[0210] In some embodiments, please continue to refer to Figures 6, 7 and 8, the first clutch member 151 and the second clutch member 152 are arranged along the first direction X, the first clutch member 151 is fixed to the sleeve 11, the second clutch member 152 is circumferentially locked with the adjustment member 13, and the second clutch member 152 is movably arranged on the adjustment member 13 along the first direction X, so that the second clutch member 152 can be engaged with or disengaged from the first clutch member 151.

[0211] Among them, the first clutch member 151 is fixed to the inner side of the sleeve 11, and the fixed connection structure between the first clutch member 151 and the sleeve 11 can be various. For example, the first clutch member 151 can be fixedly connected to the sleeve 11 by welding, bonding or clamping.

[0212] The second clutch member 152 is circumferentially locked with the adjusting member 13 and is movably arranged on the adjusting member 13 along the first direction X. That is, the second clutch member 152 can move relative to the adjusting member 13 along the first direction X but cannot rotate circumferentially relative to the adjusting member 13, so that the second clutch member 152 can engage with or disengage from the first clutch member 151 when moving along the first direction X.

[0213] Illustratively, the second clutch member 152 is sleeved on the outer side of the adjusting member 13 .

[0214] The first clutch member 151 and the second clutch member 152 are arranged along the first direction X, and the second clutch member 152 is movably provided on the adjusting member 13 along the first direction X. By fixing the first clutch member 151 to the sleeve 11 and setting the second clutch member 152 to a structure circumferentially locked with the adjusting member 13, the second clutch member 152 and the first clutch member 151 can be snapped into or disengaged by moving the second clutch member 152, so as to limit the adjusting member 13 from rotating relative to the sleeve 11 or allow the adjusting member 13 to rotate relative to the sleeve 11. The anti-loosening component 15 of this structure is simple in structure and easy to operate and implement.

[0215] According to some embodiments of the present application, referring to Figures 6, 7, and 8, and further referring to Figure 13, Figure 13 is a schematic structural diagram of the second clutch member 152 of the anti-loosening assembly 15 of the locking mechanism 10 provided in some embodiments of the present application. The adjusting member 13 includes a guide section 135 disposed within the sleeve 11, and the second clutch member 152 is movably sleeved on the outer side of the guide section 135 along the first direction X. The outer circumferential surface of the guide section 135 is provided with a first circumferential limiting portion 1351, and the inner circumferential surface of the second clutch member 152 is provided with a second circumferential limiting portion 1521. The second circumferential limiting portion 1521 cooperates with the first circumferential limiting portion 1351 to achieve circumferential locking of the second clutch member 152 and the adjusting member 13.

[0216] Among them, the guide section 135 is connected to one end of the connecting section 134, and the guide section 135 is farther away from the clamping portion 122 than the connecting section 134 in the first direction X. The first clutch member 151 is fixed in the sleeve 11 and is arranged around the adjusting member 13. The second clutch member 152 is movably mounted on the outer side of the guide section 135 of the adjusting member 13 along the first direction X, so that the second clutch member 152 can move relative to the adjusting member 13 along the first direction X, so that the second clutch member 152 can be clamped or separated from the first clutch member 151.

[0217] The outer circumferential surface of the guide section 135 is provided with a first circumferential limit portion 1351, and the inner circumferential surface of the second clutch member 152 is provided with a second circumferential limit portion 1521. The first circumferential limit portion 1351 and the second circumferential limit portion 1521 cooperate to limit the circumferential rotation of the second clutch member 152 relative to the adjusting member 13, so that when the second clutch member 152 and the first clutch member 151 are engaged with each other, the first clutch member 151 can limit the rotation of the second clutch member 152 relative to the sleeve 11, thereby further limiting the rotation of the adjusting member 13 relative to the sleeve 11.

[0218] Optionally, the first circumferential limiting portion 1351 and the second circumferential limiting portion 1521 may have various structures. For example, the first circumferential limiting portion 1351 may be a projection provided on the outer circumferential surface of the guide section 135 of the adjusting member 13, and the projection is a structure extending along the first direction X. Correspondingly, the second circumferential limiting portion 1521 is a guide groove provided on the inner circumferential surface of the second clutch member 152, and the guide groove extends along the first direction X. The projection is engaged in the guide groove, so that the second clutch member 152 can move relative to the guide section 135 of the adjusting member 13 along the first direction X and be circumferentially locked with the guide section 135 of the adjusting member 13. Of course, the first circumferential limiting portion 1351 may also be a guide groove provided on the outer circumferential surface of the guide section 135 of the adjusting member 13, and correspondingly, the second circumferential limiting portion 1521 is a projection provided on the inner circumferential surface of the second clutch member 152.

[0219] It should be noted that, in an embodiment in which an installation channel 133 is provided at one end of the adjustment member 13 and an execution part 132 is provided in the installation channel 133, the installation channel 133 is provided in the guide section 135 and passes through the end of the guide section 135 away from the connecting section 134 in the first direction X. Correspondingly, the execution part 132 is connected in the guide section 135.

[0220] The adjusting member 13 has a guide section 135, and the second clutch member 152 is movably mounted on the outside of the guide section 135 along the first direction X. By providing a first circumferential limit portion 1351 on the outer circumferential surface of the guide section 135, and correspondingly providing a second circumferential limit portion 1521 on the inner circumferential surface of the second clutch member 152 to cooperate with the first circumferential limit portion 1351, the second clutch member 152 can be moved relative to the adjusting member 13 along the first direction X and circumferentially locked.

[0221] In some embodiments, the first circumferential limiting portion 1351 is a spline extending along the first direction X, and the second circumferential limiting portion 1521 is a spline groove cooperating with the spline.

[0222] By setting the first circumferential limiting portion 1351 and the second circumferential limiting portion 1521 as a spline and a spline groove extending along the first direction X, that is, the outer circumferential surface of the guide section 135 of the adjusting member 13 is provided with a spline extending along the first direction X, and the inner circumferential surface of the second clutch member 152 is provided with a spline groove matching the spline, so that the second clutch member 152 can be circumferentially locked with the adjusting member 13 but can move relative to the adjusting member 13 along the first direction X, the structure is simple and the stability is high.

[0223] According to some embodiments of the present application, referring to Figures 6 and 13, and further referring to Figure 14, Figure 14 is a schematic structural diagram of the first clutch member 151 of the anti-loosening assembly 15 of the locking mechanism 10 provided in some embodiments of the present application. Along the first direction X, the first clutch member 151 is provided with a first toothed portion 1511 at one end facing the second clutch member 152, and the second clutch member 152 is provided with a second toothed portion 1522 at one end facing the first clutch member 151. The second toothed portion 1522 is configured to engage with the first toothed portion 1511 to achieve a snap-fit ​​engagement between the second clutch member 152 and the first clutch member 151.

[0224] The first toothed portion 1511 is a toothed structure disposed on the end of the first clutch member 151 facing the second clutch member 152. The first toothed portion 1511 has multiple teeth arranged circumferentially around the first clutch member 151, with each tooth extending radially from the first clutch member 151. The second toothed portion 1522 is a toothed structure disposed on the end of the second clutch member 152 facing the first clutch member 151. The second toothed portion 1522 has multiple teeth arranged circumferentially around the second clutch member 152, with each tooth extending radially from the second clutch member 152. When the second clutch member 152 moves in the first direction X and approaches the first clutch member 151, the second toothed portion 1522 and the first toothed portion 1511 can engage with each other, thereby achieving mutual engagement between the second clutch member 152 and the first clutch member 151, thereby restricting rotation of the adjustment member 13 relative to the sleeve 11.

[0225] It should be noted that, in other embodiments, the first clutch member 151 and the second clutch member 152 can also be other structures. For example, a limiting hole is provided at one end of the first clutch member 151 facing the second clutch member 152 in the first direction X, and a latch is provided at one end of the second clutch member 152 facing the first clutch member 151 in the first direction X. When the second clutch member 152 moves along the first direction X and approaches the first clutch member 151, the latch can be inserted into the limiting hole to achieve mutual engagement between the second clutch member 152 and the first clutch member 151, thereby limiting the rotation of the adjusting member 13 relative to the sleeve 11.

[0226] By providing a first tooth-shaped portion 1511 at one end of the first clutch member 151 facing the second clutch member 152, and correspondingly providing a second tooth-shaped portion 1522 at one end of the second clutch member 152 facing the first clutch member 151, the second tooth-shaped portion 1522 can be engaged with or disengaged from the first tooth-shaped portion 1511 when the second clutch member 152 moves in the first direction X, thereby realizing the snap-fitting or disengagement of the second clutch member 152 and the first clutch member 151, so that when the first tooth-shaped portion 1511 and the second tooth-shaped portion 1522 are engaged with each other, the first clutch member 151 and the second clutch member 152 can cooperate to limit the rotation of the adjustment member 13 relative to the sleeve 11. The structure is simple and easy to implement. In addition, by respectively arranging the first tooth-shaped portion 1511 and the second tooth-shaped portion 1522 on the first clutch member 151 and the second clutch member 152, the difficulty of engaging and disengaging the first clutch member 151 and the second clutch member 152 can be reduced, which is conducive to the mutual engagement or disengagement of the first clutch member 151 and the second clutch member 152.

[0227] According to some embodiments of the present application, as shown in FIG8 , along the first direction X, a first inclined surface 1512 is formed on one end of the first clutch member 151 facing the second clutch member 152, and a second inclined surface 1523 is formed on one end of the second clutch member 152 facing the first clutch member 151. The second inclined surface 1523 mates with the first inclined surface 1512. The first tooth-shaped portion 1511 is disposed on the first inclined surface 1512, and the second tooth-shaped portion 1522 is disposed on the second inclined surface 1523.

[0228] The second inclined surface 1523 matches the first inclined surface 1512 , that is, the first inclined surface 1512 on the first clutch 151 and the second inclined surface 1523 on the second clutch 152 have the same shape, so that the first inclined surface 1512 can fit the second inclined surface 1523 .

[0229] The first tooth-shaped portion 1511 is disposed on the first inclined surface 1512 , and the second tooth-shaped portion 1522 is disposed on the second inclined surface 1523 . That is, the first tooth-shaped portion 1511 is protruded from the first inclined surface 1512 , and the second tooth-shaped portion 1522 is protruded from the second inclined surface 1523 .

[0230] A first inclined surface 1512 is provided at one end of the first clutch member 151 facing the second clutch member 152, and the first tooth-shaped portion 1511 is provided on the first inclined surface 1512. Correspondingly, a second inclined surface 1523 that matches the first inclined surface 1512 is provided at one end of the second clutch member 152 facing the first clutch member 151, and the second tooth-shaped portion 1522 is provided on the second inclined surface 1523. This structure can achieve an inclined structure in which the first tooth-shaped portion 1511 and the second tooth-shaped portion 1522 are matched with each other, thereby playing a certain guiding role and facilitating the mutual engagement of the first tooth-shaped portion 1511 and the second tooth-shaped portion 1522.

[0231] In some embodiments, referring to FIG. 8 , FIG. 13 and FIG. 14 , the first inclined surface 1512 is a concave surface provided on the first clutch member 151 , and the second inclined surface 1523 is a convex surface provided on the second clutch member 152 .

[0232] Among them, the first inclined surface 1512 is a concave surface set on the first clutch member 151, that is, the first inclined surface 1512 is a inclined surface set at one end of the first clutch member 151 facing the second clutch member 152 and concave inward, so that the first inclined surface 1512 is a conical surface concave toward the interior of the first clutch member 151.

[0233] The second inclined surface 1523 is a convex surface provided on the second clutch member 152 , that is, the second inclined surface 1523 is provided on one end of the second clutch member 152 facing the first clutch member 151 and protrudes outward, so that the second inclined surface 1523 is a conical surface protruding toward the outside of the second clutch member 152 .

[0234] By setting the first inclined surface 1512 as a concave surface and the second inclined surface 1523 as a convex surface, the second clutch component 152 can be inserted into the first clutch component 151 when the second tooth-shaped portion 1522 of the second clutch component 152 is engaged with the first tooth-shaped portion 1511 of the first clutch component 151, thereby facilitating improving the stability and reliability of the mutual engagement between the second clutch component 152 and the first clutch component 151, thereby reducing the phenomenon of slippage between the second clutch component 152 and the first clutch component 151 when they are engaged with each other.

[0235] According to some embodiments of the present application, referring to Figures 6, 7 and 8, the anti-loosening assembly 15 may further include a second elastic member 153, which is arranged between the sleeve 11 and the second clutch member 152. The second elastic member 153 is configured to drive the second clutch member 152 to move along the first direction X toward the direction close to the first clutch member 151, so that the second clutch member 152 is engaged with the first clutch member 151.

[0236] Among them, the second elastic member 153 is arranged between the sleeve 11 and the second clutch member 152, so that the second elastic member 153 can provide elastic force for the second clutch member 152, so that the second clutch member 152 has a tendency to move in the first direction X toward the direction close to the first clutch member 151. Therefore, in actual use, it is only necessary to overcome the elastic force of the second elastic member 153 and push the second clutch member 152 to disengage to drive the adjusting member 13 to rotate relative to the sleeve 11, so as to realize the switching of the locking member 12 between the locked state and the unlocked state. After the state switching of the locking member 12 is completed, it is necessary to cancel the force pushing the second clutch member 152 so that the second clutch member 152 can be close to and clamped with the first clutch member 151 under the elastic force of the second elastic member 153, so as to realize the rotation limiting function between the adjusting member 13 and the sleeve 11.

[0237] Optionally, the second elastic member 153 may have various structures. For example, the second elastic member 153 may be a spring, a spring sheet, or elastic rubber, etc., disposed between the sleeve 11 and the second clutch member 152. For example, in Figures 6 and 8 , the second elastic member 153 is a spring that is sleeved around the outside of the guide section 135 of the adjustment member 13, with both ends of the spring respectively contacting the inner circumferential wall of the sleeve 11 and the side of the second clutch member 152 facing away from the first clutch member 151.

[0238] It should be noted that the second elastic member 153 can be arranged between the sleeve 11 and the second clutch member 152 in various structures. For example, the second elastic member 153 can be directly connected to the sleeve 11 and the second clutch member 152 at both ends, or it can be indirectly connected to the sleeve 11 and the second clutch member 152, that is, the second elastic member 153 is connected to the sleeve 11 and the second clutch member 152 through other components.

[0239] In some embodiments, as shown in Figures 6, 7 and 8, the anti-loosening assembly 15 may further include a block 154. The block 154 is connected to the sleeve 11 and surrounds the outer side of the guide section 135 of the adjusting member 13. The elastic member is sleeved on the outer side of the guide section 135 of the adjusting member 13, and the two ends of the elastic member in the first direction X are respectively in contact with the block 154 and the second clutch member 152. The anti-loosening assembly 15 with such a structure is conducive to reducing the difficulty of assembling the elastic member between the sleeve 11 and the second clutch member 152, and is conducive to improving the assembly stability of the elastic member between the sleeve 11 and the second clutch member 152, so as to alleviate the phenomenon of the elastic member falling off.

[0240] The stopper 154 is connected to the inside of the sleeve 11 and surrounds the outside of the adjustment member 13, that is, the stopper 154 is sleeved on the outside of the adjustment member 13, and the stopper 154 is connected to the inner circumferential wall of the sleeve 11. For example, the connection structure between the stopper 154 and the sleeve 11 can be various, such as welding, bonding, or clamping.

[0241] Both ends of the elastic member in the first direction X abut against the stopper 154 and the second clutch member 152 respectively, that is, one end of the elastic member abuts against the second clutch member 152 , and the other end indirectly abuts against the sleeve 11 through the stopper 154 .

[0242] The anti-loosening component 15 is also provided with a second elastic member 153, which is arranged between the sleeve 11 and the second clutch member 152. The second elastic member 153 can apply a force in the first direction X toward the first clutch member 151 to the second clutch member 152, so that the first clutch member 151 and the second clutch member 152 are engaged with each other. The anti-loosening component 15 with this structure can, on the one hand, further improve the stability of the mutual engagement between the first clutch member 151 and the second clutch member 152, so as to reduce the phenomenon of accidental disengagement of the first clutch member 151 and the second clutch member 152. On the other hand, after the second clutch member 152 and the first clutch member 151 are disengaged from each other, the second elastic member 153 can realize automatic engagement of the second clutch member 152 with the first clutch member 151, without manual intervention, and is easy to operate and use.

Optionally, the lock base 300 and the mounting frame 200 may be integral or separate structures. When the lock base 300 and the mounting frame 200 are integral, that is, the lock base 300 is part of the mounting frame 200; when the lock base 300 and the mounting frame 200 are separate structures, the lock base 300 may be connected to the mounting frame 200 by welding, bolting, or clamping. For example, in FIG2 , the lock base 300 and the mounting frame 200 are separate structures, and the lock base 300 is bolted to the mounting frame 200.

[0251] The battery assembly 100 includes a locking mechanism 10 and a battery 20 . The locking mechanism 10 is mounted on the battery 20 . The locking mechanism 10 is used to lock or unlock with the lock seat 300 to achieve battery replacement of the vehicle 1000 .

[0252] In some embodiments, as shown in FIG11 , a lock hole 310 is provided on the lock base 300 for inserting the locking member 12. The lock hole 310 passes through both sides of the lock base 300 along the first direction X. After the locking member 12 is inserted into the lock hole 310, the adjusting member 13 is rotated to drive the clamping portion 122 of the locking member 12 to rotate around the axis extending along the first direction X, so that the clamping portion 122 can be engaged with the surface of the lock base 300 on the side away from the sleeve 11, so that the locking mechanism 10 and the lock are locked. The seat 300 engages in the first direction X, thereby realizing mutual locking between the locking mechanism 10 and the lock seat 300. Conversely, when the adjusting member 13 is rotated and the clamping portion 122 of the locking member 12 is driven to rotate until the projection of the clamping portion 122 in the first direction X is located in the lock hole 310, the locking member 12 can be withdrawn from the lock hole 310, so that the locking mechanism 10 and the lock seat 300 can be disengaged in the first direction X, thereby realizing mutual unlocking between the locking mechanism 10 and the lock seat 300.

[0253] Among them, the cross-section of the locking hole 310 is rectangular. When the extension direction of the clamping portion 122 is consistent with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be inserted into the locking hole 310 or can be withdrawn from the locking hole 310. When the clamping portion 122 passes through the locking hole 310 and the extension direction of the clamping portion 122 intersects with the length direction of the cross-section of the locking hole 310, the clamping portion 122 can be engaged with the surface of the lock seat 300 on the side facing away from the sleeve 11.
