Description

Technical Field

[0001] This application relates to the field of fast battery swapping technology, and more particularly to a battery swapping device. Background Technology

[0002] The application of new energy batteries in daily life and industry is becoming increasingly widespread. For example, new energy vehicles equipped with batteries are already widely used, and batteries are also increasingly being applied in energy storage. In new energy vehicles equipped with batteries, the batteries can provide all or part of the power.

[0003] In related technologies, electric vehicles are mostly driven to battery swapping stations for battery swapping. However, if a vehicle breaks down due to power issues or battery failure in a scenario far from a battery swapping station, the battery device needs to be replaced on-site. Therefore, how to quickly and conveniently install and remove the battery device in non-battery swapping station scenarios is one of the problems that those skilled in the art need to solve. Utility Model Content

[0004] This application provides a battery replacement device that enables quick and convenient installation and removal of battery devices in non-battery swapping station scenarios.

[0005] The technical solution of this application embodiment is implemented as follows:

[0006] This application provides a battery replacement device, including: an unlocking mechanism, comprising an unlocking component for engaging with a locking accessory of a battery device along its mating direction and rotating around the mating direction to lock or unlock the battery device; a lifting mechanism, the unlocking mechanism being connected to the lifting mechanism and capable of lifting and lowering under the action of the lifting mechanism; and an angle adjustment mechanism, connected to the lifting mechanism, the lifting mechanism being capable of rotating under the action of the angle adjustment mechanism and driving the unlocking mechanism to rotate; wherein the mating direction of the unlocking component is consistent with the lifting direction of the lifting mechanism.

[0007] The battery replacement device provided in this application embodiment, through the coordinated operation of an locking / unlocking mechanism, a lifting mechanism, and an angle adjustment mechanism, allows the locking / unlocking mechanism to adjust its position in the lifting direction via the lifting mechanism and its angle to adjust its angle when performing locking or unlocking operations on the battery device. This improves its adaptability to battery devices in different positions or postures, especially in rugged, non-swapping station environments, where the device enhances the accuracy of docking between the locking / unlocking mechanism and the locking accessories of the battery device. Thus, the battery replacement device provided in this application can accurately and quickly dock with the battery device in non-swapping station environments, thereby improving the speed and convenience of battery swapping. Furthermore, when the docking direction of the unlocking component is collinear with the docking direction of the battery device's lock accessory, since the docking direction of the unlocking component is consistent with the lifting direction of the lifting mechanism, as the lifting mechanism drives the unlocking component to rise along the lifting direction, the unlocking component approaches the lock accessory along its docking direction. During this process, the docking direction of the unlocking component and the docking direction of the battery device's lock accessory are always collinear with each other. In this way, the lifting mechanism can complete the docking of the unlocking component and the battery device's lock accessory through the rising action, reducing the number of times the unlocking component needs to frequently adjust its angle to align with the lock accessory. This can reduce misalignment or interference caused by inconsistent directions and improve the efficiency and reliability of the unlocking process.

[0008] In some embodiments, the battery replacement device further includes a first translation mechanism, which includes: a base; a first translation force assembly connected to the base; and a translation member connected to the first translation force assembly, capable of reciprocating relative to the base along a first direction under the action of the first translation force assembly. The first direction intersects the lifting direction of the lifting mechanism, and the lifting mechanism is connected to the translation member through an angle adjustment mechanism.

[0009] Thus, by setting up the first translation mechanism, the position of the unlocking mechanism in the first direction can be adjusted, which can further enhance the spatial flexibility of the battery replacement device and make it easier to adapt to the needs of different installation positions. At the same time, combined with the lifting and angle adjustment functions, the overall positioning accuracy and ease of operation are improved.

[0010] In some embodiments, the first translational force assembly includes: a first translational drive member connected to the base; a first lead screw extending along a first direction, the output end of the first translational drive member being connected to the first lead screw for driving the first lead screw to rotate; and a first engaging member connected to the translational member, the first engaging member being sleeved on the first lead screw and capable of driving the translational member to move along the first direction as the first lead screw rotates.

[0011] Thus, by forming a first clearance groove in the translation component and setting a meshing component and a first lead screw in the first clearance groove, the space occupied is reduced, making the structure compact, which is conducive to the miniaturization of the battery replacement device and makes it easier to move to non-battery swapping station scenarios for battery swapping operations.

[0012] In some embodiments, the translation member has two protrusions spaced apart along a second direction, and a first clearance groove is formed between the two protrusions. The second direction intersects the first direction and the lifting direction. At least a portion of the first engagement member is located in the first clearance groove and is connected to the inner wall of the first clearance groove. At least a portion of the first lead screw is located in the first clearance groove and passes through the first engagement member.

[0013] Thus, the cooperation between the first slide groove and the first slide rail enhances the guiding and stability of the translation component during movement and improves the accuracy of position adjustment along the first direction.

[0014] In some embodiments, of the translation member and the base, one is formed with a first slide rail extending in a first direction, and the other is formed with a first slide groove, wherein the first slide rail and the first slide groove are slidably engaged.

[0015] Thus, by setting up a rotating connection structure and a pushing component, the angle can be flexibly adjusted, allowing the lifting mechanism to rotate freely within a certain range, thereby adapting to the operational needs under complex working conditions. Moreover, placing the rotating connection structure within the first clearance slot can save space, promote a compact structure, facilitate the miniaturization of the battery swapping device, and make it easier to move it to non-swapping station scenarios for battery swapping operations.

[0016] In some embodiments, at least one protrusion has a first rotatable connection structure formed on the surface facing the first clearance groove. The angle adjustment mechanism includes: a second rotatable connection structure disposed on the lifting mechanism, wherein one of the first rotatable connection structure and the second rotatable connection structure is a connecting shaft extending along a second direction, and the other is a connecting hole, wherein the connecting shaft rotatably passes through the connecting hole; and a pusher connected to the translation member, configured to enable the lifting mechanism to rotate around the central axis of the connecting shaft by pushing against the lifting mechanism.

[0017] Thus, by setting up a rotating connection structure and a pushing component, the angle can be flexibly adjusted, allowing the lifting mechanism to rotate freely within a certain range, thereby adapting to the operational needs under complex working conditions. Moreover, the lifting mechanism is partially located within the first clearance slot, which saves space, promotes a compact structure, facilitates the miniaturization of the battery swapping device, and makes it easier to move it to non-battery swapping station locations for battery swapping operations.

[0018] In some embodiments, the pushing member includes a threaded member with external threads, and a threaded through hole is formed in the bottom wall of the first relief groove. The threaded member passes through the threaded through hole and is threadedly connected to the threaded through hole. One end of the threaded member extends from the side of the translation member facing the first relief groove and abuts against the lifting mechanism, while the other end extends from the side facing away from the first relief groove, and the extended part serves as a screwing part.

[0019] Thus, by using threaded parts as the pushing parts, it is not only easy to manually adjust the angle, but also to achieve precise positioning, thereby improving the controllability and convenience of operation.

[0020] In some embodiments, the battery replacement device further includes a second translation mechanism, which includes: a base; a second translation force component connected to the base, the base being connected to the second translation force component and capable of reciprocating relative to the base along a second direction under the action of the second translation force component, the second direction intersecting the first direction and the lifting direction.

[0021] Thus, the addition of a second translation mechanism further enhances the flexibility of adjusting the unlocking mechanism, improving the positioning accuracy and ease of operation of the battery replacement device.

[0022] In some embodiments, the second translational force assembly includes: a second translational drive member connected to the base; a second lead screw extending along a second direction, the output end of the second translational drive member being connected to the second lead screw for driving the second lead screw to rotate; and a second engagement member connected to the base body, the second engagement member being sleeved on the second lead screw and capable of driving the base body to move along the second direction as the second lead screw rotates.

[0023] Therefore, using a lead screw drive structure to achieve translational motion has the advantages of compact structure and smooth operation, which helps to improve the accuracy and stability of translation, thereby improving the smoothness of subsequent unlocking and unlocking operations.

[0024] In some embodiments, the base has a second clearance groove, the second lead screw extends into the second clearance groove along the second direction, the second engaging member is connected to the side of the base facing the base and is at least partially disposed in the second clearance groove, one of the base and the base has a second slide rail extending along the second direction, and the other has a second slide groove, the second slide rail and the second slide groove are slidably engaged.

[0025] Thus, by setting up a second clearance groove, space can be rationally utilized, resulting in space savings and a more compact structure. This facilitates the miniaturization of the battery swapping device and makes it easier to move it to non-swapping station locations for battery swapping operations. Furthermore, the second clearance groove also saves materials and reduces weight. The cooperation between the second slide rail and the second slide groove enhances the smoothness and reliability of the unlocking mechanism's position adjustment along the second direction, and improves the accuracy of position adjustment along the second direction.

[0026] In some embodiments, the lifting mechanism includes: a lifting base connected to a translation member via an angle adjustment mechanism; a lifting power assembly connected to the upper part of the lifting base; a lifting member connected to the upper part of the lifting power assembly, the lifting member being able to move up and down relative to the lifting base under the action of the lifting power assembly; and an unlocking mechanism connected to one end of the lifting member along a second direction.

[0027] In this way, by setting up a lifting power component and lifting parts, the lifting movement of the unlocking mechanism is realized. This structure helps to improve the flexibility and accuracy of operation, and also enhances the adaptability of the battery replacement device in complex environments.

[0028] In some embodiments, the lifting power assembly includes: a lifting drive member; a third lead screw extending along a first direction, the output end of the lifting drive member being connected to the third lead screw for driving the third lead screw to rotate; a third engagement member sleeved on the third lead screw and capable of reciprocating along the first direction as the third lead screw rotates; a first connecting rod, both ends of which are rotatably connected to the third engagement member and the lifting base, respectively; a second connecting rod, both ends of which are rotatably connected to the third engagement member and the lifting member, respectively; a third connecting rod and a fourth connecting rod, one end of the third connecting rod and one end of the fourth connecting rod being rotatably connected to the lifting base and the lifting member, respectively; and a transition member, the other ends of the third connecting rod and the other ends of the fourth connecting rod being rotatably connected via the transition member, the transition member being disposed on the third lead screw and fixed in position relative to the third lead screw in the first direction.

[0029] Thus, during the rotation of the third lead screw driven by the lifting drive component, the third engaging component can be driven to move towards or away from the adapter along the first direction, thereby changing the angles between the first, second, third, and fourth links. This, in turn, increases or decreases the distance between the lifting base and the lifting component, realizing the lifting function of the lifting mechanism. Furthermore, by setting up a multi-link structure, the smoothness of the lifting component's lifting movement is improved, enhancing the movement accuracy and battery swapping reliability of the battery replacement device.

[0030] In some embodiments, the locking / unlocking mechanism includes a locking / unlocking drive and a deceleration mechanism. The locking / unlocking drive is connected to the output end of the locking / unlocking drive through the deceleration mechanism. The locking / unlocking drive can rotate under the action of the locking / unlocking drive and the deceleration mechanism to lock or unlock the battery device.

[0031] In this way, by setting up locking and unlocking drive components and deceleration mechanisms, controllable rotation of the locking and unlocking components is achieved, which not only improves the flexibility and accuracy of operation, but also effectively reduces energy consumption and extends service life.

[0032] In some embodiments, the unlocking mechanism further includes an elastic element, the bottom end of which is formed with a groove, the output end of the deceleration mechanism is movably inserted into the groove, the elastic element is accommodated in the groove and clamped between the output end of the deceleration mechanism and the bottom wall of the groove, and the unlocking drive and the lifting element are respectively connected to opposite sides of the deceleration mechanism along the second direction.

[0033] Thus, by incorporating an elastic component, a buffering function is achieved between the unlocking / unlocking component and the deceleration mechanism, which helps reduce the occurrence of jamming and thereby improves the operational reliability of the battery swapping device. By connecting the unlocking / unlocking drive component and the lifting component to opposite sides of the deceleration mechanism along the second direction, and by rationally arranging the positions of the drive component and the lifting component, the height of the battery swapping device can be reduced, improving the overall structural compactness and facilitating the miniaturization of the battery swapping device. This makes it easier to move the device to non-battery swapping station locations for battery swapping operations.

[0034] In some embodiments, the battery replacement device further includes: a base, a lifting mechanism and an angle adjustment mechanism, all located on the upper part of the base; multiple wheels, including omnidirectional wheels, installed on the lower part of the base; and a push handle connected to the base.

[0035] In this way, by setting up a base, wheels, and push handle, the entire battery replacement device is easy to move and position, improving the convenience and flexibility of on-site use. Attached Figure Description

[0060] The following is a detailed description of this application.

[0061] The application of new energy batteries in daily life and industry is becoming increasingly widespread. New energy batteries are not only used in energy storage systems for hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, and electric trucks, as well as in aerospace and other fields. With the continuous expansion of the application areas of power batteries, the market demand is also constantly increasing.

[0062] Currently, most electric vehicles need to travel to battery swapping stations to swap batteries. However, if a vehicle breaks down due to battery issues or malfunctions in a location far from a battery swapping station, the battery needs to be replaced on-site. Therefore, how to quickly and conveniently install and remove battery devices in non-battery swapping station locations is one of the problems that needs to be solved by those in the field.

[0063] In related technologies, common battery swapping devices include an unlocking mechanism and a lifting mechanism. The lifting action allows the unlocking component of the unlocking mechanism to fit over the locking accessory of the battery device. Rotating the unlocking component then rotates the locking accessory, thereby releasing the lock between the battery device and the vehicle's battery mounting bracket. However, the inventors of this application have noted that in non-battery swapping station scenarios, the ground where the vehicle is located is usually uneven. When the battery swapping device and the vehicle are parked on such ground, the extension direction of the inner cavity of the unlocking component is often inconsistent with the extension direction of the locking accessory. Even with lifting or horizontal adjustment of the unlocking mechanism's position, it is difficult for the battery swapping device to properly align with the locking accessory of the battery device, thus affecting the speed and convenience of battery installation and removal.

[0064] This application addresses the problems existing in the aforementioned related technologies by proposing a battery replacement device, including an locking / unlocking mechanism, a lifting mechanism, and an angle adjustment mechanism. The locking / unlocking mechanism is configured to lock or unlock the battery device. The locking / unlocking mechanism is connected to the lifting mechanism and can move up and down under the action of the lifting mechanism. The angle adjustment mechanism is connected to the lifting mechanism, and the lifting mechanism can rotate under the action of the angle adjustment mechanism, thereby driving the locking / unlocking mechanism to rotate.

[0065] The battery swapping device provided in this application, in scenarios outside of battery swapping stations, especially when the vehicle is parked on uneven ground, where the battery unit mounted on the vehicle's battery mounting bracket is tilted, or the battery swapping device itself is tilted, can adjust the orientation of the locking / unlocking mechanism via an angle adjustment mechanism. This allows the locking / unlocking mechanism to more effectively align with the locking accessory of the battery unit. Combined with the lifting mechanism, accurate docking between the locking / unlocking mechanism and the locking accessory of the battery unit can be achieved. Thus, the battery swapping device provided in this application can accurately and quickly dock with the battery unit in scenarios outside of battery swapping stations, thereby improving the speed and convenience of battery swapping.

[0066] In the following embodiments, for ease of explanation, a vehicle 1000 is used as an example. The description is as follows with reference to the accompanying drawings.

[0067] Figure 1 This is a structural schematic diagram of a vehicle 1000 according to one or more embodiments.

[0068] Vehicle 1000 can be a fuel-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid vehicles, or range-extended vehicles, etc. The vehicle can be a commercial vehicle. This application embodiment does not impose any special restrictions on the aforementioned vehicles.

[0069] like Figure 1 As shown, a battery device 100 is installed inside the vehicle 1000. The battery device 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery device 100 can be used to power the vehicle 1000; for example, the battery device 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.

[0070] In some embodiments of this application, the battery device 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0071] In some embodiments of this application, the vehicle 1000 includes a chassis and a body mounted on the chassis. The body forms the vehicle exterior and passenger compartment and protects the occupants located in the passenger compartment. The chassis is located below the body and carries the engine, battery unit 100, and other components.

[0072] For example, the chassis includes a battery mounting bracket, which is a skeletal structure of the chassis for mounting the battery device, and may consist of multiple crossbeams and multiple longitudinal beams. The battery device 100 is mounted on the battery mounting bracket.

[0073] Figure 2 This is an exploded structural diagram of a battery device 100 according to one or more embodiments.

[0074] like Figure 2 As shown in this embodiment, the battery device 100 may include one or more battery cell assemblies 101 for providing voltage and capacity. Each battery cell assembly 101 may include multiple battery cells, which can be connected in series, parallel, or mixed connections via a busbar.

[0075] In some embodiments, the battery cell assembly 101 is typically formed by arranging a plurality of battery cells.

[0076] A single battery cell can be a rechargeable battery. A rechargeable battery is a battery cell that can be recharged after it has been discharged, allowing the active materials to be activated and the cell to continue to be used.

[0077] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and this application does not specifically limit it.

[0078] As an example, the battery cell assembly 101 can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As an example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0079] In some embodiments, the battery device 100 may be a battery pack, which may include a battery case 102 and one or more battery cell assemblies 101, the battery cell assemblies 101 being housed in the battery case 102.

[0080] As an example, the battery cell assembly 101 can be a battery module, and the battery cell assembly 101 can be housed in the battery box 102 by fixing the battery module in the battery box 102.

[0081] As an example, the battery cell assembly 101 can also be housed in the battery box 102 by directly fixing multiple battery cells to the battery box 102.

[0082] As an example, the battery box 102 may include a first box body 1021 and a second box body 1022. The first box body 1021 and the second box body 1022 are fastened together to form a closed space inside the battery box 102 to house the battery cell assembly 101. Here, "closed" refers to covering or closing, which can be sealed or unsealed. The first box body 1021 can be a top cover, and the second box body 1022 can be a bottom plate, or the first box body 1021 can be a bottom plate, and the second box body 1022 can be a top cover.

[0083] Below, refer to Figures 3 to 13 Some embodiments of this application will be described in detail.

[0085] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a lifting direction are defined. These three directions intersect each other, including perpendicular intersections. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions are perpendicular to each other. For ease of explanation, as... Figures 5 to 12 As shown by the arrows, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the upward and downward direction. The direction that arrow Z points in along the upward and downward direction is called "up," and its opposite direction is called "down."

[0086] Embodiments of this application provide a battery replacement device, such as... Figures 3 to 9 As shown, the battery replacement device includes an unlocking mechanism 1, a lifting mechanism 2, and an angle adjustment mechanism 3. The unlocking mechanism 1 is configured to lock or unlock the battery device 100. The unlocking mechanism 1 is connected to the lifting mechanism 2 and can be raised and lowered under the action of the lifting mechanism 2. The angle adjustment mechanism 3 is connected to the lifting mechanism 2, and the lifting mechanism 2 can rotate under the action of the angle adjustment mechanism 3, thereby driving the unlocking mechanism 1 to rotate.

[0087] The locking / unlocking mechanism 1 refers to a mechanical structure used to lock or unlock the battery device 100. For example, such as... Figure 5 and Figure 6 As shown, the unlocking mechanism 1 may include an unlocking member 11 with an internal hexagonal hole, and... Figure 3 and Figure 4 The locking and unlocking mechanism 11 engages with the rotating nut (also known as the locking accessory 103) at the mounting point of the battery device 100. Driven by the drive motor, the locking / unlocking mechanism 11 rotates, causing the rotating nut and the T-bolt 104 threadedly connected to the rotating nut to rotate. This causes the T-bolt 104 to rotate 90°, allowing its head to switch between a position where it can pass through the mounting hole 401 of the battery mounting bracket 400 of the vehicle 1000 and a position where it cannot pass through the mounting hole 401 of the battery mounting bracket 400, thus completing the locking and unlocking of the battery device 100. For example, the locking / unlocking mechanism 1 may also include a reduction mechanism 13 (e.g., a multi-stage gear transmission system) to amplify torque and adapt to the installation and removal requirements of battery devices 100 of different specifications.

[0088] The lifting mechanism 2 is a mechanical structure used to drive the unlocking mechanism 1 to rise and fall. It can consist of a lifting power component 22 (such as a motor, lead screw, etc.) and a support structure. The height of the unlocking mechanism 1 can be adjusted in the lifting direction Z, allowing the unlocking mechanism 1 to move closer to or further away from the locking accessory 103 of the battery device 100. For example, the lifting mechanism 2 can be a scissor lift, where the angle between the lifting arms of the scissor lift changes through the cooperation of the lead screw and nut, thereby driving the unlocking mechanism 1 to rise or fall. Alternatively, the lifting mechanism 2 can also be composed of an electric push rod, where the extension and retraction of the push rod is driven by a motor to achieve the lifting action of the lifting mechanism 2.

[0089] The angle adjustment mechanism 3 refers to the structure used to adjust the tilt angle of the lifting mechanism 2 and the unlocking mechanism 1. This structure enables precise alignment during the entire assembly and disassembly process even under non-horizontal conditions, further improving the applicability of the device in complex terrain. For example, the angle adjustment mechanism 3 may include a pair of support bolts. By adjusting the height difference between the support bolts on the left and right sides, the tilt angle of the lifting mechanism 2 is changed, allowing the lifting mechanism 2 to adapt to uneven ground. Alternatively, the angle adjustment mechanism 3 may also include a rotating component driven by a hydraulic cylinder or electric motor. The rotation of the rotating component causes the lifting mechanism 2 to rotate, thereby adjusting the angle of the lifting mechanism 2.

[0090] The angle adjustment mechanism 3 can be configured to drive the lifting mechanism 2 to rotate in various directions around a central point. For example, the angle adjustment mechanism 3 includes a ball joint. The angle adjustment mechanism 3 can also be configured to drive the lifting mechanism 2 to reciprocate around a central axis. For example, the angle adjustment mechanism 3 includes a rotary connecting shaft.

[0091] The battery replacement device provided in this application embodiment, through the coordinated operation of an unlocking / unlocking mechanism 1, a lifting mechanism 2, and an angle adjustment mechanism 3, allows the unlocking / unlocking mechanism 1 to adjust its position in the lifting direction Z via the lifting mechanism 2 and its angle via the angle adjustment mechanism 3 when performing locking or unlocking operations on the battery device 100. This improves its adaptability to battery devices 100 in different positions or postures, especially in rugged, non-battery swapping station environments. This battery replacement device can improve the accuracy of docking between the unlocking / unlocking mechanism 1 and the locking accessory 103 of the battery device 100. Thus, the battery replacement device provided in this application embodiment can accurately and quickly dock with the battery device 100 in non-battery swapping station environments, thereby improving the speed and convenience of battery swapping.

[0092] In some embodiments, such as Figure 5 and Figure 6 As shown, the locking / unlocking mechanism 1 includes a locking / unlocking member 11, which is used to engage with the lock attachment 103 of the battery device 100 along its docking direction and rotate around the docking direction to lock or unlock the battery device 100. The docking direction of the locking / unlocking member 11 is consistent with the lifting direction Z of the lifting mechanism 2.

[0093] It is understandable that the mating direction of the unlocking component 11 refers to the assembly direction when the unlocking component 11 and the locking accessory 103 of the battery device 100 are connected. For example, if the unlocking component 11 is a sleeve and the locking accessory 103 of the battery device 100 is a shaft, and the two need to be assembled along a straight line, then the direction of the central axis of the sleeve is the mating direction of the unlocking component 11. Or, for another example, if the unlocking component 11 is a shaft and the locking accessory 103 of the battery device 100 is a sleeve, and the two need to be assembled along a straight line, then the direction of the central axis of the shaft is the mating direction of the unlocking component 11.

[0094] For example, the unlocking component 11 is a sleeve structure with a polygonal hole, and the end of the locking accessory 103 of the battery device 100 is set as a polygonal shaft. The docking direction of the unlocking component 11 is the direction of the central axis of the sleeve structure, and the docking direction of the locking accessory 103 is the direction of the central axis of the polygonal shaft.

[0095] It is understood that the lifting direction Z of the lifting mechanism 2 refers to the direction of movement of the load or worktable in the lifting mechanism 2 relative to the reference part. For example, the lifting mechanism 2 includes a lifting base 21, a lifting power assembly 22, and a lifting component 23. The lifting power assembly 22 is connected above the lifting base 21, and the lifting component 23 is connected above the lifting power assembly 22. The lifting component 23 can move closer to or away from the lifting base 21 under the action of the lifting power assembly 22, thereby realizing the lifting of the lifting component 23. The direction along which the lifting component 23 moves closer to or away from the lifting mechanism 2 is the lifting direction Z. The relative angle between the lifting direction Z of the lifting mechanism 2 and the direction of gravity is related to the posture of the lifting mechanism 2. For example, if the lifting base 21 and the lifting component 23 of the lifting mechanism 2 are both parallel plates, the lifting power component 22 drives the lifting component 23 to move closer to or away from the lifting base 21 in a direction perpendicular to the lifting base 21. If the lifting base 21 is placed on a horizontal surface, the lifting component 23 moves up and down along the direction of gravity. In this case, the lifting direction Z of the lifting mechanism 2 is consistent with the direction of gravity. However, if the lifting base 21 is placed on an inclined surface intersecting the horizontal surface, the lifting component 23 moves up and down in a direction intersecting the direction of gravity. In this case, the lifting direction Z of the lifting mechanism 2 intersects the direction of gravity, and the two are not consistent. Therefore, under the action of the angle adjustment mechanism 3, the lifting mechanism 2 will rotate, which can change the angle between the lifting direction Z of the lifting mechanism 2 and the direction of gravity, and will also simultaneously change the angle between the docking direction of the unlocking component 11 and the direction of gravity.

[0096] Thus, when the docking direction of the unlocking component 11 is collinearly aligned with the docking direction of the lock accessory 103 of the battery device 100, since the docking direction of the unlocking component 11 is consistent with the lifting direction Z of the lifting mechanism 2, as the lifting mechanism 2 drives the unlocking component 11 to rise along the lifting direction Z, the unlocking component 11 approaches the lock accessory 103 along its docking direction. During this process, the docking direction of the unlocking component 11 and the docking direction of the lock accessory 103 of the battery device 100 are always collinearly aligned. In this way, the lifting mechanism 2 can complete the docking of the unlocking component 11 and the lock accessory 103 of the battery device 100 by rising, reducing the number of times the unlocking component 11 needs to frequently adjust its angle to align with the lock accessory 103, reducing misalignment or interference caused by inconsistent directions, and improving the efficiency and reliability of the unlocking process.

[0097] Of course, it is understood that the docking direction of the locking and unlocking component 11 is not limited to the lifting direction Z of the lifting mechanism 2. In some embodiments, the docking direction of the locking and unlocking component 11 may intersect with the lifting direction Z of the lifting mechanism 2.

[0098] In some embodiments, such as Figure 5 and Figure 8As shown, the battery replacement device also includes a first translation mechanism 4, which includes a base 41, a first translation force assembly 42, and a translation component 43. The first translation force assembly 42 is connected to the base 41; the translation component 43 is connected to the first translation force assembly 42 and can reciprocate relative to the base 41 along the first direction X under the action of the first translation force assembly 42. The first direction X intersects the lifting direction Z. The lifting mechanism 2 is connected to the translation component 43 through the angle adjustment mechanism 3.

[0099] The first translation mechanism 4 is a mechanical structure that can drive the angle adjustment mechanism 3, the lifting mechanism 2 and the locking / unlocking mechanism 1 to reciprocate along the first direction X, so as to adjust the position of the locking / unlocking mechanism 1, thereby facilitating the locking / unlocking component 11 of the locking / unlocking mechanism 1 to approach and align with the locking accessory 103 of the battery device 100.

[0100] Thus, by setting the first translation mechanism 4, the position of the unlocking mechanism 1 in the first direction X can be adjusted, which can further enhance the spatial flexibility of the battery replacement device and make it easier to adapt to the needs of different installation positions. At the same time, combined with the lifting and angle adjustment functions, the overall positioning accuracy and operation convenience are improved.

[0101] Of course, it is understood that the battery replacement device is not limited to including the first translation mechanism 4. In some embodiments, the battery replacement device does not include the first translation mechanism 4 for adjusting the position in the first direction X. The position of the unlocking mechanism 1 in the first direction X can be changed by pushing the overall position of the battery replacement device.

[0102] In some embodiments, such as Figure 8 As shown, the first translational force assembly 42 includes a first translational drive 421, a first lead screw 422, and a first engagement member 423. The first translational drive 421 is connected to the base 41. The first lead screw 422 extends along the first direction X. The output end of the first translational drive 421 is connected to the first lead screw 422 and is used to drive the first lead screw 422 to rotate. The first engagement member 423 is connected to the translation member 43. The first engagement member 423 is sleeved on the first lead screw 422 and can drive the translation member 43 to reciprocate along the first direction X as the first lead screw 422 rotates.

[0103] For example, the first translation drive 421 can be, but is not limited to, an electric motor, a hydraulic motor, or a pneumatic motor.

[0104] For example, the first engaging member 423 can be, but is not limited to, a nut, which is directly threaded into the first lead screw 422. During the rotation of the first lead screw 422, the nut moves along the first direction X, thereby driving the translation member 43 to move along the first direction X.

[0105] For example, the first engaging member 423 may include, but is not limited to, a nut and a ball, with the nut sleeved on the first lead screw 422 and a ball between the first lead screw 422 and the nut, thus changing sliding friction into rolling friction.

[0106] For example, the first engaging element 423 may include, but is not limited to, a nut and planetary rollers (a plurality of threaded rollers), the planetary rollers revolving around the first lead screw and rotating on their own axis while engaging with the threads in the nut.

[0107] Therefore, using a lead screw drive structure to achieve translational motion has the advantages of compact structure and smooth operation, which helps to improve the accuracy and stability of translation, thereby improving the smoothness of subsequent unlocking and unlocking operations.

[0108] Of course, those skilled in the art should understand that the first translational power component 42 is not limited to a transmission form including a lead screw and nut. As long as it can realize the movement of the lifting mechanism 2 along the first direction X, the first translational power component 42 may also include gear and rack transmission, chain transmission, belt transmission, etc.

[0109] In some embodiments, such as Figure 8 As shown, the translation member 43 has two protrusions 431 spaced apart along the second direction Y. The translation member 43 forms a first clearance groove 432 between the two protrusions 431. The second direction Y intersects the first direction X and the lifting direction Z. At least a portion of the first engaging member 423 is located in the first clearance groove 432 and is connected to the inner wall of the first clearance groove 432. At least a portion of the first lead screw 422 is located in the first clearance groove 432 and passes through the first engaging member 423.

[0110] For example, the surface of the translation member 43 facing away from the base 41 has a protrusion 431 and a first clearance groove 432.

[0111] For example, the first clearance groove 432 includes a groove bottom wall 4321 and two groove side walls 4322 opposite each other along the second direction Y. The groove bottom wall 4321 is connected to both groove side walls 4322. The groove bottom wall 4321 and the two groove side walls 4322 form an opening along one end edge of the first direction X. The groove bottom wall 4321 and the two groove side walls 4322 form another opening along the other end edge of the first direction X. The first engaging member 423 is located in the first clearance groove 432 and is connected to the groove bottom wall 4321 of the first clearance groove 432. The first lead screw 422 passes through the two openings and the first clearance groove 432.

[0112] For example, the base 41 is a rectangular frame structure. The length direction of the base 41 is consistent with the first direction X, and the width direction is consistent with the second direction Y. The dimension of the base 41 along the first direction X is larger than the dimension of the translation member 43 along the first direction X. The first translation drive member 421 is installed on the frame edge of one end of the base 41 along the first direction X. One end of the first lead screw 422 is connected to the output end of the first translation drive member 421, and the other end of the first lead screw 422 is rotatably connected to the frame edge of the other end of the base 41 along the first direction X.

[0113] Thus, by forming a first clearance groove 432 in the translation member 43 and setting a first engaging member 423 and a first lead screw 422 in the first clearance groove 432, the space occupied is reduced, making the structure compact, which is conducive to the miniaturization of the battery replacement device and makes it easier to move to non-battery swapping station scenarios for battery swapping operations.

[0114] Of course, it is understood that the translation member 43 is not limited to forming the protrusion 431 and the first clearance groove 432. In some embodiments, the translation member 43 is a plate of uniform thickness.

[0115] In some embodiments, such as Figure 8 As shown, of the translation member 43 and the base 41, one is formed with a first slide rail 411 extending along the first direction X, and the other is formed with a first slide groove. The first slide rail 411 and the first slide groove are slidably engaged.

[0116] For example, the translation member 43 has a first groove formed on the side opposite to the two protrusions 431, and the surface of the base 41 facing the translation member 43 has a first slide rail 411 formed at both ends along the second direction Y. The two first grooves and the two first slide rails 411 are slidably connected in a one-to-one correspondence. In this way, the thickness of the corresponding protrusions 431 of the translation member 43 is relatively thick, which is sufficient to provide the first groove without causing the solid part of the translation member 43 to be too thin and affecting the structural strength.

[0117] Thus, the cooperation between the first slide groove and the first slide rail 411 enhances the guiding and stability of the translation component 43 during movement and improves the accuracy of position adjustment along the first direction X.

[0118] Of course, it is understood that the translation member 43 and the base 41 are not limited to being slidably connected by slide rails and grooves. In some embodiments, the translation member 43 and the base 41 are not provided with slide rails and grooves.

[0119] In some embodiments, such as Figure 8 and Figure 9As shown, at least one protrusion 431 has a first rotating connection structure 4311 formed on the surface facing the first clearance groove 432. The angle adjustment mechanism 3 includes a second rotating connection structure 31 and a pushing member 32. The second rotating connection structure 31 is provided on the lifting mechanism 2. One of the first rotating connection structure 4311 and the second rotating connection structure 31 is a connecting shaft extending along the second direction Y, and the other is a connecting hole. The connecting shaft is rotatably inserted through the connecting hole. The pushing member 32 is connected to the translation member 43 and is configured to allow the lifting mechanism 2 to rotate around the central axis of the connecting shaft by pushing against it.

[0120] For example, such as Figure 8 As shown, the first rotating connection structure 4311 is a connection hole, that is, at least one protrusion 431 has a connection hole formed on the surface facing the first clearance groove 432. The lifting mechanism 2 is connected to a connecting shaft that serves as the second rotating connection structure 31. The connecting shaft passes through the connection hole, and the lifting mechanism 2 can rotate around the central axis of the connecting shaft together with the connecting shaft.

[0121] For example, the pusher 32 may only abut against the lifting mechanism 2 (which can be separated), or it may be rotatably connected in addition to abutting against the lifting mechanism 2 (which cannot be separated).

[0122] Thus, by setting up a rotating connection structure and a pushing member 32, the angle can be flexibly adjusted, allowing the lifting mechanism 2 to rotate freely within a certain range, thereby adapting to the operational needs under complex working conditions. Moreover, it also allows part of the lifting mechanism 2 to be located within the first clearance groove 432, which can save space, promote a compact structure, facilitate the miniaturization of the battery swapping device, and make it easier to move it to non-battery swapping station scenarios for battery swapping operations.

[0123] Of course, it is understood that the angle adjustment mechanism 3 is not limited to the above structure. In some embodiments, the angle adjustment mechanism 3 includes a rotary drive device (e.g., a rotary motor) capable of driving the connecting shaft to rotate about its own central axis.

[0124] In some embodiments, such as Figure 9 As shown, the pusher 32 includes a threaded member with external threads. The bottom wall 4321 of the first clearance groove 432 is formed with a threaded through hole. The threaded member passes through the threaded through hole and is threadedly connected to the threaded through hole. One end of the threaded member extends from the side of the translation member 43 facing the first clearance groove 432 and abuts against the lifting mechanism 2. The other end extends from the side away from the first clearance groove 432 and the extended part serves as a screwing part.

[0125] It is understandable that threaded parts can be, but are not limited to, bolts, studs, screws, etc.

[0126] For example, the threaded part is a bolt, the head of the bolt is located on the side of the threaded through hole facing away from the first relief groove 432, and the head of the bolt is used as the screwing part, which can be easily screwed.

[0127] Understandably, the screwing part can be used for manual screwing or can be equipped with a drive component and a transmission assembly. The transmission assembly connects the screwing part and the drive component, and can transmit the motion of the drive component to the screwing part, thereby driving the threaded part to rotate.

[0128] Thus, by using a threaded part as the pushing part 32, it is not only easy to manually adjust the angle, but also to achieve precise positioning, thereby improving the controllability and convenience of operation.

[0129] Of course, it can be understood that the pushing member 32 is not limited to using a threaded part. In some embodiments, the pushing member 32 can be a telescopic structure (such as a cylinder or telescopic rod). The telescopic structure is installed on the translation member 43, and the telescopic output end of the telescopic structure is connected to the lifting mechanism 2. In this way, the angle of the lifting mechanism 2 can be adjusted by the telescopic structure.

[0130] In some embodiments, such as Figure 9 As shown, at least two pushers 32 are provided, and at least one pusher 32 is provided on each of the opposite sides of the second rotating connection structure 31 along the first direction X.

[0131] For example, the second rotary connection structure 31 has a pusher 32 on each of its opposite sides along the first direction X.

[0132] In this way, at least two parts of the lifting mechanism 2 are pushed, which can improve the smoothness of the angle adjustment of the lifting mechanism 2 and improve the stability and accuracy of the angle adjustment.

[0133] Of course, it is understood that the pusher 32 is not limited to at least two. In some embodiments, there may be one pusher 32. The pushing end of the pusher 32 is in contact with and rotatably connected to the lifting device. When the pusher 32 is pushed upward, it can cause the lifting mechanism 2 to rotate in one clockwise direction. When the pusher 32 is pulled downward, it can drive the lifting mechanism 2 to rotate in the opposite clockwise direction.

[0134] In some embodiments, such as Figure 12 As shown, the battery replacement device also includes a second translation mechanism 5. The second translation mechanism 5 includes a base 51 and a second translation force component 52. The second translation force component 52 is connected to the base 51. The base 41 is connected to the second translation force component 52 and can reciprocate relative to the base 51 along the second direction Y under the action of the second translation force component 52. The second direction Y intersects the first direction X and the lifting direction Z.

[0135] It is understandable that the second translation mechanism 5 can drive the base 41 to reciprocate in the second direction Y, thereby causing the first translation mechanism 4, the angle adjustment mechanism 3, the lifting mechanism 2 and the unlocking mechanism 1 to reciprocate along the second direction Y, thereby adjusting the position of the unlocking mechanism 1 in the second direction Y.

[0136] Thus, by setting up the second translation mechanism 5, the flexibility of adjusting the unlocking mechanism 1 can be further enhanced, and the positioning accuracy and ease of operation of the battery replacement device can be improved.

[0137] Of course, it is understood that the battery replacement device is not limited to including the second translation mechanism 5. In some embodiments, the battery replacement device does not include the second translation mechanism 5 for adjusting the position in the second direction Y. The position of the unlocking mechanism 1 in the second direction Y can be changed by pushing the entire battery replacement device.

[0138] In some embodiments, such as Figure 12 As shown, the second translational force assembly 52 includes a second translational drive 521, a second lead screw 522, and a second engagement member 523. The second translational drive 521 is connected to the base 51. The second lead screw 522 extends along the second direction Y. The output end of the second translational drive 521 is connected to the second lead screw 522 to drive the second lead screw 522 to rotate. The second engagement member 523 is connected to the base 41 and is sleeved on the second lead screw 522. It can drive the base 41 to move along the second direction Y as the second lead screw 522 rotates.

[0139] For example, the second translation drive 521 can be, but is not limited to, an electric motor, a hydraulic motor, or a pneumatic motor.

[0140] For example, the second engaging member 523 can be, but is not limited to, a nut, which is directly threaded into the second lead screw 522. During the rotation of the second lead screw 522, the nut moves along the second direction Y, thereby driving the base 41 to move along the second direction Y.

[0141] For example, the second engaging member 523 may include, but is not limited to, a nut and balls, with the nut sleeved on the second lead screw 522 and balls between the second lead screw 522 and the nut, thus changing sliding friction into rolling friction.

[0142] For example, the second engagement member 523 may include, but is not limited to, a nut and planetary rollers (a plurality of threaded rollers), which revolve around the second lead screw and rotate on their own axis while engaging with the threads in the nut.

[0143] Therefore, using a lead screw drive structure to achieve translational motion has the advantages of compact structure and smooth operation, which helps to improve the accuracy and stability of translation, thereby improving the smoothness of subsequent unlocking and unlocking operations.

[0144] Of course, those skilled in the art should understand that the second translational power assembly 52 is not limited to a transmission form including a lead screw and nut. As long as it can realize the movement of the lifting mechanism 2 along the second direction Y, it is acceptable. For example, the second translational power assembly 52 may also include gear and rack transmission, chain transmission, belt transmission, etc.

[0145] In some embodiments, such as Figure 12 As shown, the base 51 has a second clearance groove 511, the second lead screw 522 extends into the second clearance groove 511 along the second direction Y, and the second engagement member 523 is connected to the side of the base 41 facing the base 51 and is at least partially disposed in the second clearance groove 511.

[0146] For example, the base 51 is a rectangular frame structure. The length direction of the base 51 is consistent with the first direction X, and the width direction is consistent with the second direction Y. The second translation drive 521 is connected to one end face of the base 51 along the second direction Y.

[0147] Thus, by setting up the second clearance slot 511, space can be rationally utilized, saving space and promoting a compact structure. This facilitates the miniaturization of the battery swapping device and makes it easier to move it to non-swapping station locations for battery swapping operations. In addition, the setting of the second clearance slot 511 also saves materials and reduces weight.

[0148] Of course, it is understood that the base 51 is not limited to having a clearance groove. In some embodiments, the base 51 is a plate of uniform thickness without a clearance groove, and the second lead screw 522 is located above the base 51.

[0149] In some embodiments, such as Figure 12 As shown, of the two components, the base 51 and the base body 41, one is formed with a second slide rail 512 extending along the second direction Y, and the other is formed with a second slide groove. The second slide rail 512 and the second slide groove are slidably engaged.

[0150] For example, a second slide groove is formed on each of the two edges of the surface of the base 41 facing the base 51 along the first direction X, and a second slide rail 512 is formed on each of the two edges of the surface of the base 51 facing the base 41 along the first direction X. The two second slide grooves and the two second slide rails 512 are slidably connected in a one-to-one correspondence.

[0151] Thus, the cooperation between the second slide groove and the second slide rail 512 enhances the smoothness and reliability of the locking / unlocking mechanism 1 in adjusting its position along the second direction Y, and improves the accuracy of the position adjustment along the second direction Y.

[0152] Of course, it is understood that the base 41 and the base 51 are not limited to being slidably connected by slide rails and grooves. In some embodiments, the base 41 and the base 51 are not provided with slide rails and grooves.

[0153] In some embodiments, such as Figure 7 As shown, at least a portion of the unlocking mechanism 1 is located on one side of the lifting mechanism 2 along the second direction Y.

[0154] It is understandable that when projected along the second direction Y into the same projection plane, the projection of the unlocking mechanism 1 and the projection of the lifting mechanism 2 have overlapping parts.

[0155] Thus, by arranging the unlocking mechanism 1 on one side of the lifting mechanism 2 along the second direction Y, the size of the battery swapping device in the lifting direction Z can be reduced, which is conducive to the miniaturization of the battery swapping device, thereby enhancing its adaptability in confined spaces and making it easier to move to non-battery swapping station scenarios for battery swapping operations.

[0156] In some embodiments, such as Figure 9 and Figure 10 As shown, the lifting mechanism 2 includes a lifting base 21, a lifting power assembly 22, and a lifting component 23. The lifting base 21 is connected to the translation component 43 through an angle adjustment mechanism 3. The lifting power assembly 22 is connected to the upper part of the lifting base 21. The lifting component 23 is connected to the upper part of the lifting power assembly 22. The lifting component 23 can be raised and lowered relative to the lifting base 21 under the action of the lifting power assembly 22. The unlocking mechanism 1 is connected to the lifting component 23 at one end along the second direction Y.

[0157] Understandably, the direction of relative movement between the lifting component 23 and the lifting base 21 under the action of the lifting power component 22 is the lifting direction Z. During the rotation of the lifting mechanism 2 under the action of the angle adjustment mechanism 3, the lifting direction Z of the lifting mechanism 2 will also change relative to the horizontal plane. The battery device 100 of the vehicle 1000 is usually installed at the bottom of the chassis of the vehicle 1000. The battery replacement device needs to be positioned below the chassis to operate. Therefore, during the battery replacement process, the lifting direction Z of the lifting mechanism 2 always forms an angle with the horizontal plane. The lifting mechanism 2 can raise the position of the unlocking component 11 through upward operation and lower the position of the unlocking component 11 through downward operation.

[0158] For example, such as Figure 9 As shown, the lifting base 21 is connected to a second rotating connection structure 31, which is a connecting shaft. The connecting shaft extends into a connecting hole formed in the translation member 43, realizing the rotating connection between the lifting mechanism 2 and the translation member 43. The top of the pushing member 32 abuts against the bottom of the lifting base 21.

[0159] Thus, by setting up the lifting power assembly 22 and the lifting component 23, the lifting movement of the unlocking mechanism 1 is realized. This structure helps to improve the flexibility and accuracy of operation, and also enhances the adaptability of the battery replacement device in complex environments.

[0160] In some embodiments, such as Figure 10 As shown, the lifting power assembly 22 includes a lifting drive component 221, a third lead screw 222, a third engagement component 223, a first connecting rod 224, a second connecting rod 225, a third connecting rod 226, a fourth connecting rod 227, and a converter 228. The third lead screw 222 extends along the first direction X. The output end of the lifting drive component 221 is connected to the third lead screw 222 to drive the third lead screw 222 to rotate. The third engagement component 223 is sleeved on the third lead screw 222 and can reciprocate along the first direction X as the third lead screw 222 rotates. Both ends of the first connecting rod 224 are rotatably connected to the third engaging member 223 and the lifting base 21, respectively; both ends of the second connecting rod 225 are rotatably connected to the third engaging member 223 and the lifting member 23, respectively; one end of the third connecting rod 226 and one end of the fourth connecting rod 227 are rotatably connected to the lifting base 21 and the lifting member 23, respectively; the other end of the third connecting rod 226 and the other end of the fourth connecting rod 227 are rotatably connected through the adapter 228, which is located on the third lead screw 222 and fixed in position relative to the third lead screw 222 in the first direction X.

[0161] For example, the lifting drive 221 can be, but is not limited to, an electric motor, a hydraulic motor, or a pneumatic motor.

[0162] For example, such as Figure 11 As shown, the third engaging member 223 includes a main body 2231 and two extensions 2232. The two extensions 2232 are respectively connected to opposite sides of the main body 2231 along the second direction Y. The main body 2231 has an engaging hole 2233 extending along the first direction X. The third lead screw 222 passes through the main body 2231 through the engaging hole 2233 and is threadedly engaged with the engaging hole 2233. The first connecting rod 224 and the second connecting rod 225 are rotatably connected to the two extensions 2232.

[0163] For example, both ends of the adapter 228 along the second direction Y are rotatably connected to the third link 226 and the fourth link 227. The middle part of the adapter 228 has a through hole extending along the first direction X. The third lead screw 222 passes through the through hole, and there is a gap between the third lead screw 222 and the hole wall. The adapter 228 is fixedly connected to the housing of the lifting drive 221 through a fixed connector. In this way, the position of the adapter 228 relative to the third lead screw 222 in the first direction X is fixed. It can be understood that the relative position of the adapter 228 and the third lead screw 222 in the first direction X remains unchanged, and the third lead screw 222 can rotate about the central axis of the third lead screw 222 relative to the adapter 228.

[0164] Thus, during the rotation of the third lead screw 222 driven by the lifting drive component 221, the third engaging component 223 can be driven to move towards or away from the adapter 228 along the first direction X, thereby changing the angle between the first link 224, the second link 225, the third link 226, and the fourth link 227. This, in turn, increases or decreases the distance between the lifting base 21 and the lifting component 23, realizing the lifting function of the lifting mechanism 2. Furthermore, by setting a multi-link structure, the smoothness of the lifting movement of the lifting component 23 is improved, enhancing the movement accuracy and battery swapping reliability of the battery replacement device.

[0165] In some embodiments, such as Figure 6 and Figure 7 As shown, the battery replacement device also includes a monitoring probe 6, which is connected to the upper part of the lifting component 23.

[0166] For example, the battery replacement device also includes a control device (not shown in the figure). The control device is communicatively connected to the lifting drive 221, the first translation drive 421, the second translation drive 521, and the unlocking drive 12. The control device can control the start and stop of the lifting drive 221, the first translation drive 421, the second translation drive 521, and the unlocking drive 12. The monitoring probe 6 can be connected to a client such as a tablet or mobile phone via a wireless communication network. The client can observe the images captured by the monitoring probe 6 and remotely control the start and stop of the lifting drive 221, the first translation drive 421, the second translation drive 521, and the unlocking drive 12. In this way, the docking and unlocking of the unlocking device 11 with the locking accessory 103 of the battery device 100 can be completed conveniently and quickly.

[0167] By setting up a monitoring probe 6 and installing it on the upper part of the lifting mechanism 2, the monitoring probe 6 can capture images of a wider range and closer to the battery device 100, realizing real-time monitoring of the operation process. This not only improves the safety of operation but also helps operators to detect and handle abnormal situations in a timely manner, thereby improving overall work efficiency and reliability.

[0168] In some embodiments, such as Figure 7 As shown, the locking / unlocking mechanism 1 includes a locking / unlocking drive 12, a reduction mechanism 13, and a locking / unlocking component 11. The locking / unlocking component 11 is connected to the output end of the locking / unlocking drive 12 through the reduction mechanism 13. The locking / unlocking component 11 can rotate under the action of the locking / unlocking drive 12 and the reduction mechanism 13 to lock or unlock the battery device 100.

[0169] The reduction mechanism 13 is a mechanical transmission device that can reduce speed and increase torque. It converts high-speed, low-torque power input into low-speed, high-torque power output. Examples include gear reducers and planetary reducers.

[0170] The unlocking / unlocking drive component 12 can be, but is not limited to, an electric motor, a hydraulic motor, or a pneumatic motor.

[0171] Thus, by setting up the unlocking / unlocking drive component 12 and the deceleration mechanism 13, controllable rotation of the unlocking / unlocking component 11 is achieved, which not only improves the flexibility and accuracy of operation, but also effectively reduces energy consumption and extends service life.

[0172] Of course, it is understood that the unlocking mechanism 1 is not limited to including the deceleration mechanism 13. In some embodiments, the unlocking mechanism 1 does not include the deceleration mechanism 13.

[0173] In some embodiments, such as Figure 13 As shown, the unlocking mechanism 1 also includes an elastic member 14. The bottom end of the unlocking member 11 has a groove 111. The output end of the deceleration mechanism 13 is movably inserted into the groove 111. The elastic member 14 is accommodated in the groove 111 and is sandwiched between the output end of the deceleration mechanism 13 and the bottom wall 4321 of the groove 111.

[0174] For example, the elastic element 14 can be, but is not limited to, a helical spring, a bending spring, a rubber part, a bellows, etc.

[0175] Thus, by setting the elastic element 14, a buffer function is achieved between the unlocking / unlocking element 11 and the deceleration mechanism 13, which helps to reduce the occurrence of jamming and thereby improves the operational reliability of the battery replacement device.

[0176] Of course, it is understood that the locking / unlocking component 11 and the deceleration mechanism 13 are not limited to having an elastic element 14. In some embodiments, the locking / unlocking component 11 and the deceleration mechanism 13 are not provided with an elastic element 14, and the two are rigidly connected.

[0177] In some embodiments, the unlocking / unlocking drive 12 and the lifting member 23 are respectively connected to opposite sides of the deceleration mechanism 13 along the second direction Y.

[0178] In this way, by rationally arranging the positions of the drive components and lifting components 23, it is beneficial to reduce the height of the battery swapping device, improve the overall structural compactness, facilitate the miniaturization of the battery swapping device, and make it easier to move to non-swapping station scenarios for battery swapping operations.

[0179] In some embodiments, such as Figures 5 to 7 As shown, the battery replacement device also includes a base 51, a push handle 7, and multiple wheels 8. The lifting mechanism 2 and the angle adjustment mechanism 3 are both located on the upper part of the base 51; the multiple wheels 8 are installed on the lower part of the base 51, and the multiple wheels 8 include casters; the push handle 7 is connected to the base 51.

[0180] Thus, by setting up the base 51, the wheels 8 and the push handle 7, the entire battery replacement device is easy to move and position, improving the convenience and flexibility of on-site use.

[0181] In some embodiments, such as Figures 5 to 7 As shown, the battery replacement device also includes a monitoring probe 6, which is installed on the upper part of the lifting mechanism 2 and is arranged with the unlocking mechanism 1 in a direction that intersects with the lifting direction Z of the lifting mechanism 2.

[0182] In this way, by rationally arranging the positions of the monitoring probes 6, the field of view coverage is expanded, making it easier to fully grasp the operation situation and improve the efficiency and reliability of the operation.

[0183] The following describes specific examples of some embodiments of this application with reference to the accompanying drawings.

[0184] As a concrete example, a disassembly and assembly trolley (battery replacement device) is provided. The disassembly and assembly trolley includes a bottom frame (base 51), a middle frame (base 41), an upper frame (translation component 43), a scissor lift (lifting mechanism 2), a push rod (push handle 7), a disassembly and assembly deceleration mechanism (deceleration mechanism 13), a monitoring probe (monitoring probe 6), a disassembly and assembly sleeve (locking and unlocking component 11), a first drive motor (second translation drive component 521), a second drive motor (first translation drive component 421), and a third drive motor (lifting drive component 221). The fourth drive motor (unlocking drive component 12) allows the middle frame to move relative to the bottom frame. The first drive motor (second translation drive component 521) drives the second lead screw 522 on the bottom frame (base 51) to rotate. The second lead screw 522 engages with the second nut (second engagement component 523) connected below the middle frame, which can transmit the power of the first drive motor to the middle frame. The bottom frame and the middle frame also engage with the second slide groove and the second slide rail 512. The middle frame can move relative to the bottom frame along the direction of the second slide rail 512. The movement of the upper frame relative to the middle frame is achieved by the second drive motor (first translation drive 421) driving the first lead screw 422 on the middle frame to rotate. The first lead screw 422 engages with the first nut (first engaging member 423) on the upper side of the middle frame, transmitting the power of the second drive motor to the upper frame. The middle frame and the upper frame also engage through the first slide groove and the first slide rail 411, allowing the upper frame to move relative to the middle frame along the direction of the first slide rail 411. The remote control corresponds to the third drive motor, causing the scissor lift lifting and disassembly reduction mechanism 13 to move in the lifting direction Z while simultaneously driving the disassembly sleeve (locking and unlocking member 11) to rotate slowly at a low torque. The scissor lifting mechanism 2 includes a base (lifting base 21), lifting arms (first link 224, second link 225, third link 226 and fourth link 227), a rotating shaft (third meshing member 223), and a third lead screw 222. The rotating shaft has a threaded hole inside, which is threadedly engaged with the third lead screw 222. When the third drive motor drives the third lead screw 222 to rotate, the engagement of the rotating shaft with the threaded hole can change the included angle between the lifting arms (first link 224, second link 225, third link 226 and fourth link 227) to complete the lifting. The scissor lift mechanism 2 can be connected to the connecting hole (first rotating connection structure 4311) on the upper frame via the connecting shaft (second rotating connection structure 31) on the base, and supported by bolts (push member 32); by adjusting the support height difference between the left and right support bolts, the deflection angle of the scissor lift relative to the upper frame can be adjusted, and the entire disassembly and assembly trolley enters the bottom of the vehicle 1000 to be disassembled and assembled. By adjusting the angle, the mounting point to be disassembled and assembled (lock accessory 103 of battery device 100) can be aligned when the ground is uneven.The disassembly and assembly sleeve (with unlocking component 11) can move vertically in the disassembly and assembly reduction mechanism 13. A spring (elastic component 14) is installed between them to reduce the likelihood of the disassembly and assembly reduction mechanism 13 jamming during cap removal and retrieval. After the shear-type lifting mechanism 2 moves to the preset height and the disassembly and assembly sleeve has successfully retrieved the cap, the fourth drive motor corresponding to the disassembly and assembly reduction mechanism 13 outputs a large torque to quickly disassemble and retrieval the corresponding mounting point.
