Description

[0001] This application claims priority to Chinese patent application CN202111444383.8, filed on November 30, 2021. The entire contents of the aforementioned Chinese patent application are incorporated herein by reference. Technical Field

[0002] This invention relates to a battery pack swapping mobile component and a battery swapping shuttle. Background Technology

[0003] Fast-swap electric vehicles can meet their power needs by replacing battery packs. However, for large vehicles, such as heavy or light trucks, the large vehicle body and cargo weight result in high battery pack capacity requirements, necessitating a sufficiently large energy capacity to support a range of hundreds of kilometers. Therefore, in current technology, large new energy vehicles typically use a top-mounted method to fix a large battery container to the vehicle's frame, with the container positioned close to the cab. This creates significant safety hazards for the driver and the vehicle during driving and the battery swapping process; moreover, battery malfunctions can directly cause personal injury to the driver. Furthermore, the top-mounted method requires a large site for the battery swapping station, necessitating a sufficiently large area for hoisting equipment to transfer and store batteries, leading to high construction costs.

[0004] Therefore, a safer, more reliable, and easier-to-use battery swapping method is urgently needed for large vehicles. During battery pack replacement, a fully charged battery pack needs to be moved to the bottom of the electric vehicle using a battery pack swapping moving assembly to align it with the battery mounting bracket. The depleted battery pack also needs to be unlocked from its mounting bracket, removed, and placed on the battery pack swapping moving assembly for removal from the bottom of the electric vehicle. However, during the unlocking and moving of the battery pack, and after unlocking, uneven placement can cause the battery pack to fall and damage it. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the battery pack is easily dropped due to unstable placement during the transportation of the battery pack, which in turn causes damage to the battery pack. The present invention provides a battery pack swapping mobile component and a battery swapping shuttle.

[0006] The present invention solves the above-mentioned technical problems through the following technical solution:

[0007] The present invention provides a battery pack swapping mobile assembly, which is installed on a battery swapping shuttle. The battery pack swapping mobile assembly includes a mobile plate for placing and moving the battery pack, and tray mounting areas are provided on both sides of the mobile plate for mounting trays that support the battery pack.

[0008] In this design, the aforementioned structural form allows the battery pack placed on the tray to move along with the movable plate, facilitating operator control. Furthermore, a pre-designed tray mounting area is provided on the movable plate to prevent contact interference between the tray and the movable plate during installation. Located on both sides of the movable plate, the tray mounting area ensures that the battery pack's load-bearing surface is on either side after successful installation, improving stability. Moreover, the tray mounting area's location on only the sides of the movable plate prevents the tray from completely covering it, saving materials and reducing the overall weight of the device.

[0009] Preferably, the movable plate is provided with a positioning area, and the tray mounting area is located on both sides of the positioning area. The positioning area is used to install a first positioning element capable of positioning the battery pack.

[0010] In this solution, the above-mentioned structure is adopted. The battery pack is placed on the tray, and the first positioning member located between the trays can position the battery pack and drive the battery pack to move, so as to make the force even when moving the battery pack.

[0011] Preferably, the tray mounting area is provided with a flexible battery pack support, which can compress the height of the flexible battery pack support when the tray is used to place the battery pack.

[0012] In this solution, the above-mentioned structure allows for cushioning when the battery pack is placed on the tray. When the battery pack is attached to the chassis, the elastic battery pack support enables horizontal movement of the tray, allowing for a certain degree of offset error between the battery pack and the bottom of the vehicle.

[0013] Preferably, a second positioning element is installed in the tray mounting area. The second positioning element is used to insert into the corresponding positioning slot in the battery pack. When the battery pack is placed on the tray, the second positioning element passes through the tray and is inserted into the positioning slot.

[0014] In this solution, the above-mentioned structure ensures that when the battery pack is placed on the tray, the second positioning component can cooperate with the positioning slot in the battery pack to achieve positioning of the battery pack. By controlling the movement of the moving plate, the second positioning component inserted into the battery pack pulls the battery pack to move, realizing the function of the battery pack moving with the movement of the moving plate. Moreover, the battery pack is not easy to fall off, further facilitating the operator to control the movement of the battery pack.

[0015] Preferably, the elastic battery pack support includes a spring, which is detachably connected to the movable plate.

[0016] In this solution, the aforementioned structural form provides good spring extension and contraction performance at a low cost. Furthermore, the spring and the movable plate are detachably connected, facilitating spring disassembly and installation, and allowing for easy replacement of parts should either the spring or the movable plate be damaged.

[0017] Preferably, the spring is a rectangular spring.

[0018] In this solution, the above-mentioned structural form is adopted, which results in a rectangular spring with large supporting force and good durability.

[0019] Preferably, the movable plate has a protrusion, and the spring is sleeved on the outer periphery of the protrusion.

[0020] In this solution, the above-mentioned structural form is adopted, and the spring is sleeved on the protrusion to realize the installation of the spring. The installation is quick, and the protrusion for installing the spring is pre-set on the moving plate, thereby greatly improving the assembly efficiency.

[0021] Preferably, the tray mounting area is provided with an unlocking component, which cooperates with the unlocking mechanism on the battery pack to achieve unlocking, and the position of the unlocking component corresponds to the through hole of the tray.

[0022] In this design, the aforementioned structure allows the unlocking component to extend from its corresponding through-hole and trigger the unlocking mechanism on the battery pack as the moving plate moves closer to the vehicle floor. This unlocking mechanism enables the battery pack to be unlocked from the vehicle, resulting in a compact structure. Furthermore, the unlocking component is installed within the tray mounting area, specifically within the battery pack placement area, ensuring that it can trigger the unlocking mechanism on the battery pack and improving operational accuracy.

[0023] Preferably, the unlocking component is an unlocking rod, which includes a first positioning part and a second positioning part. The first positioning part is located at one end of the second positioning part away from the moving plate and has a guide part. The second positioning part is located on the moving plate, and the battery pack is moved by cooperating with the side wall of the positioning hole of the battery pack.

[0024] In this solution, the above-mentioned structure is adopted. By controlling the movement of the moving plate, the unlocking lever inserted into the battery pack can also pull the battery pack to move, thereby realizing the function of the battery pack moving with the moving plate and preventing the battery pack from falling off.

[0025] Preferably, the positioning area has a notch located on the side of the positioning area, and the first positioning member is located on the center line of the notch.

[0026] In this design, the aforementioned structural form is adopted, with a notch in the positioning area, which saves materials and reduces the weight of the entire device. Two tray mounting areas are located on either side of the positioning area, meaning the two trays are respectively located on either side of the notch in the moving plate. The first positioning element is located on the center line of the notch, which helps improve the stability of the battery pack placement, ensuring the battery pack is placed smoothly.

[0027] Preferably, the first positioning element is located on the center line of symmetry between the two trays.

[0028] In this solution, the above-mentioned structural form is adopted. The first positioning component located between the two trays can position the battery pack and drive the battery pack to move, which further facilitates the uniform force distribution when moving the battery pack.

[0029] Preferably, the height of the first positioning member extending beyond the movable plate is greater than the height of the unlocking member extending beyond the movable plate.

[0030] In this solution, the above-mentioned structural form is adopted to ensure that the battery pack can be positioned by the first positioning member, so that the battery pack can move with the moving plate and is not easy to fall off.

[0031] Preferably, the unlocking element is a torque unlocking lever, which is used to apply torque to cooperate with the unlocking mechanism to achieve unlocking.

[0032] The above-mentioned structural form is adopted in this solution for ease of operation.

[0033] The present invention also provides a battery swapping shuttle vehicle, the battery swapping shuttle vehicle including a lifting mechanism, a vehicle body positioning component and a battery pack swapping moving component as described above, the vehicle body positioning component and the battery pack swapping moving component are disposed on the lifting mechanism, and the vehicle body positioning component and the battery pack swapping moving component are movable relative to the lifting mechanism along a first direction.

[0034] In this solution, the above-mentioned structural form is adopted, and the battery pack swapping mobile component is applied to the battery swapping shuttle. When the mobile plate moves, the battery pack placed on the tray can move accordingly, which makes it easy for the operator to control the movement of the battery pack. When replacing the battery pack, the battery pack can be moved up and down by the lifting mechanism, which makes it easy for the operator to control the movement and installation of the battery pack.

[0035] Preferably, the movable plate has a notch on one side perpendicular to the first direction, and the vehicle positioning component is at least partially located inside the notch.

[0036] In this solution, the above-mentioned structural form and the spatial arrangement of the vehicle positioning component and the moving plate reduce the space occupied by the two when they are set separately, making the use of space more reasonable.

[0037] Preferably, the vehicle positioning assembly includes a first plate and a second plate stacked together, the first plate being flush with the movable plate, the second plate being located above the horizontal plane of the movable plate, and the second plate having a vehicle positioning element for positioning with the battery swapping vehicle.

[0038] In this solution, the aforementioned structural form is adopted, with the first and second plates stacked together to increase strength, making the vehicle positioning component less prone to bending or breakage during use. Furthermore, the vehicle positioning component of the second plate is used to position the battery pack swapping mobile component on the swapping vehicle, preventing relative displacement between the swapping shuttle and the swapping vehicle during battery pack installation, which would affect the installation accuracy and efficiency of the battery pack.

[0039] Preferably, the movable plate is fixedly connected to the power output structure of the drive mechanism, and the drive mechanism is used to drive the movable plate to move along the first direction, which is the direction of movement of the battery pack during the locking and unlocking process.

[0040] In this solution, the above-mentioned structure is adopted. The moving plate moves through the drive mechanism, thereby driving the battery pack to move, improving automation efficiency and facilitating operation. Since the moving plate moves along the unlocking and unlocking direction of the battery pack, the battery pack can be unlocked and unlocked during the movement.

[0041] Preferably, the movable plate is provided with a slider, which is slidably disposed on a guide rail along the first direction.

[0042] In this solution, the above-mentioned structural form is adopted. Through the sliding cooperation of the guide rail and the slider, the frictional resistance encountered by the moving plate during the movement on the guide rail is reduced, the movement is smoother, and the movement efficiency is improved.

[0043] The positive and progressive effects of this invention are as follows:

[0044] When the moving plate in the battery pack swapping moving assembly of the present invention moves, the battery pack placed on the tray can move accordingly, facilitating operator control of the battery pack's movement. Furthermore, a tray mounting area is pre-set on the moving plate to prevent contact interference between the tray and the moving plate during installation. The tray mounting area is located on both sides of the moving plate; after successful battery pack installation, the force-bearing surface of the battery pack is located on both sides, contributing to improved stability of the battery pack placement. Moreover, since the tray mounting area is only located on both sides of the moving plate, the tray does not completely cover the top of the moving plate, saving materials and reducing the overall weight of the device.

[0110] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.

[0111] This invention provides a battery pack swapping mobile assembly 1, which is mounted on a battery swapping shuttle vehicle 2. Please also refer to... Figures 1 to 16The battery pack swapping moving assembly 1 includes a moving plate 11, which is used to place and move the battery pack. Tray mounting areas 111 are provided on both sides of the moving plate 11, where trays 1111 supporting the battery packs are mounted. When the moving plate 11 moves, the battery packs placed on the trays 1111 can move accordingly, facilitating operator control of the battery pack movement. Furthermore, the tray mounting areas 111 are pre-set on the moving plate 11 to prevent contact interference between the trays 1111 and the moving plate 11 during installation. The tray mounting areas 111 are located on both sides of the moving plate 11; after successful battery pack installation, the force-bearing surfaces of the battery pack are located on both sides, which helps improve the stability of the battery pack placement. Moreover, the tray mounting areas 111 are only located on both sides of the moving plate 11, so that the trays 1111 do not completely cover the top of the moving plate 11, saving materials and reducing the overall weight of the device.

[0112] The movable plate 11 is provided with a positioning area 112, and the tray mounting area 111 is located on both sides of the positioning area 112. The positioning area 112 is used to install the first positioning member 1121 that can position the battery pack. The battery pack is placed on the tray 1111, and the first positioning member 1121 located between the two trays can position the battery pack and drive the battery pack to move, so as to ensure that the force is evenly distributed when moving the battery pack.

[0113] The pallet mounting area 111 is provided with a flexible battery pack support 1112, which can compress the height of the flexible battery pack support 1112 when the battery pack is placed on the pallet 1111. When the battery pack is placed on the pallet 1111, the flexible battery pack support 1112 provides cushioning. When the battery pack is attached to the chassis under the vehicle, the flexible battery pack support 1112 enables the horizontal movement of the pallet 1111, allowing for a certain degree of offset error between the battery pack and the bottom of the chassis.

[0114] In other embodiments, a second positioning member is installed in the tray mounting area 111. The second positioning member is used to insert into the corresponding positioning slot in the battery pack. When the battery pack is placed on the tray 1111, the second positioning member passes through the tray 1111 and inserts into the positioning slot. This ensures that when the battery pack is placed on the tray 1111, the second positioning member can cooperate with the positioning slot in the battery pack to achieve positioning of the battery pack. By controlling the movement of the moving plate 11, the second positioning member inserted into the battery pack pulls the battery pack to move, realizing the function of the battery pack moving with the movement of the moving plate 11. Moreover, the battery pack is not easy to fall off, further facilitating the operator to control the movement of the battery pack. Specifically, both the first and second positioning members include a first component and a second component. The first component is located at the end of the second component away from the moving plate and has a guide surface. The second component is located on the moving plate, and the battery pack is moved by cooperating with the side wall of the positioning hole. The lower surface of the battery pack has a slot as the first and second positioning members.

[0115] The flexible battery pack support 1112 includes a spring 11121, which is detachably connected to the movable plate 11. The spring 11121 has good telescopic performance and low cost. Furthermore, the detachable connection between the spring 11121 and the movable plate 11 facilitates the removal and installation of the spring 11121 and allows for easy replacement of parts in case of damage to either the spring 11121 or the movable plate 11. Specifically, the spring 11121 is a rectangular spring. Rectangular springs have high supporting force and good durability.

[0116] In this embodiment, the movable plate 11 is provided with a protrusion 11122, and the spring 11121 is sleeved on the outer periphery of the protrusion 11122. The spring 11121 is sleeved on the protrusion 11122 to realize the installation of the spring 11121, which is quick and easy. Furthermore, the protrusion 11122 for installing the spring 11 is pre-set on the movable plate 11, which greatly improves the assembly efficiency.

[0117] Specifically, such as Figure 2 As shown, a protrusion 11122 is installed at the corner of each tray mounting area 111. Along the length of the moving plate 11, the protrusions 11122 are arranged in three rows and two columns. Correspondingly, springs 11121 are arranged in three rows and two columns. The battery pack has good stability when it is placed on the tray 1111 and moves up and down. One end of the spring 11121 is sleeved on the protrusion 11122 and abuts against the upper surface of the moving plate 11, and the other end abuts against the lower surface of the tray 1111.

[0118] The tray mounting area 111 is equipped with an unlocking component 1113, which cooperates with the unlocking mechanism on the battery pack to achieve unlocking. The unlocking component 1113 is positioned corresponding to the through hole 11111 of the tray 1111. When the moving plate 11 moves towards the vehicle floor, the unlocking component 1113 extends out of the corresponding through hole 1111 and triggers the unlocking mechanism on the battery pack, thereby unlocking the battery pack from the vehicle. The structure is compact. In addition, the unlocking component 1113 is installed within the tray mounting area 111, that is, within the battery pack placement area, ensuring that the unlocking component 1113 can trigger the unlocking mechanism on the battery pack, thus improving operational accuracy.

[0119] The unlocking component is an unlocking lever, which includes a first positioning part and a second positioning part. The first positioning part is located at the end of the second positioning part away from the moving plate and has a guide part. The second positioning part is disposed on the moving plate, and the battery pack is moved by engaging with the side wall of the positioning hole of the battery pack. By controlling the movement of the moving plate, the unlocking lever inserted into the battery pack can also pull the battery pack to move, further realizing the function of the battery pack moving with the movement of the moving plate and preventing the battery pack from falling out.

[0120] A notch 1122 is provided within the positioning area 112, located on the side of the positioning area. The first positioning element 1121 is located on the center line of the notch 1122. Specifically, a notch is made on the side of the positioning area 112 to form the notch 1122. The notch in the positioning area 112 saves material and reduces the weight of the entire device. Two tray mounting areas 111 are located on both sides of the positioning area 112, that is, the two trays 1111 are respectively located on both sides of the notch 1122 of the moving plate 11. The first positioning element 1121 is located on the center line of the notch 1122, which helps to improve the stability of the battery pack placement, ensuring that the battery pack is placed stably.

[0121] The first positioning element 1121 is located on the symmetrical center line between the two trays 1111. The first positioning element 1121, located between the two trays 1111, can position the battery pack and drive the battery pack to move, further facilitating the uniform force distribution when moving the battery pack.

[0122] The height of the first positioning member 1121 extending from the moving plate 11 is greater than the height of the unlocking member 1113 extending from the moving plate 11, ensuring that the battery pack can be positioned by the first positioning member 1121, so that the battery pack can move with the moving plate 11 and is not easy to fall off.

[0123] The unlocking component 1113 is a torque unlocking lever, which is used to apply torque to cooperate with the unlocking mechanism to achieve unlocking, making it easy to operate.

[0124] The present invention also provides a battery swapping shuttle 2, such as Figure 3 To and Figure 6 As shown. The battery swapping shuttle 2 includes a lifting mechanism 21, a vehicle positioning component 22, and a battery pack swapping moving component 1 as described in any of the above embodiments. The vehicle positioning component 22 and the battery pack swapping moving component 1 are mounted on the lifting mechanism 21 and can move relative to the lifting mechanism 21 in a first direction. When the battery pack swapping moving component 1 is applied to the battery swapping shuttle 2, the battery pack placed on the tray 1111 can move accordingly when the moving plate 11 moves, making it convenient for the operator to control the movement of the battery pack. When replacing the battery pack, the lifting mechanism 21 is used to move the battery pack up and down, making it convenient for the operator to control the movement and installation of the battery pack.

[0125] like Figure 7 and Figure 8As shown, the lifting mechanism 21 includes a lifting drive assembly 211 and a cam 212. The lifting drive assembly 211 and the cam 212 are coaxially arranged. The cam 212 includes a cam body and a connecting part. The connecting part has a slide groove. The cam body is disposed in the slide groove. The connecting part is connected to the battery pack swapping moving assembly 1. The lifting drive assembly 211 rotates and drives the cam body to slide in the slide groove, and drives the connecting part to move in the vertical direction, thereby realizing the lifting of the battery pack swapping moving assembly 1.

[0126] The movable plate 11 has a notch 1122 on one side perpendicular to the first direction, and the vehicle body positioning component 22 is at least partially located inside the notch 1122. The spatial arrangement of the vehicle body positioning component 22 and the movable plate 11 reduces the space occupied by the two when they are installed separately, making the use of space more reasonable.

[0127] The vehicle positioning assembly 22 includes a first plate 221 and a second plate 222 stacked together. The first plate 221 is flush with the moving plate 11, and the second plate 222 is located above the horizontal plane of the moving plate 11. The second plate 222 has a vehicle positioning element for positioning with the battery swapping vehicle. The stacked arrangement of the first plate 221 and the second plate 222 increases strength, making the vehicle positioning assembly 22 less prone to bending or breakage during use. Furthermore, the vehicle positioning element of the second plate 222 is used to position the battery pack swapping mobile assembly 1 on the battery swapping vehicle, preventing relative displacement between the battery swapping shuttle 2 and the battery swapping vehicle during battery pack installation, which would affect the installation accuracy and efficiency of the battery pack. Specifically, the vehicle positioning element is a vehicle positioning pin.

[0128] The movable plate 11 is fixedly connected to the power output structure of the drive mechanism 23. The drive mechanism 23 is used to drive the movable plate 11 to move along a first direction, which is the direction in which the battery pack moves during the locking and unlocking process. The first direction is along... Figure 5 The moving plate 11 extends in the width direction. The moving plate 11 moves through the drive mechanism 23, thereby driving the battery pack to move, improving automation efficiency and facilitating operation; since the moving plate 11 moves along the unlocking and unlocking direction of the battery pack, the battery pack can be unlocked and unlocked during the movement.

[0129] A slider 231 is provided on the movable plate 11, and the slider 231 is slidably mounted on the guide rail 232 along the first direction. Through the sliding engagement of the guide rail 232 and the slider 231, the frictional resistance experienced by the movable plate 11 during its movement on the guide rail 232 is reduced, resulting in smoother movement and improved efficiency. Please also refer to... Figures 9 to 13During the unlocking process, the vehicle positioning component 22 and the battery pack swapping moving component 1 are driven to move in the first direction by the drive mechanism 23. Both the vehicle positioning component 22 and the battery pack swapping moving component 1 are mounted on the lifting mechanism 21, so that the vehicle positioning component 22 and the battery pack swapping moving component 1 are adjusted to a suitable position according to the position of the vehicle positioning hole and the position of the battery pack of the vehicle to be swapped. The battery swapping shuttle 2 moves to the underside of the vehicle body, and the lifting mechanism 21 lifts and lowers to position the vehicle positioning component 22 with the vehicle body. The battery pack swapping moving component 1 moves the battery pack and the unlocking component through the drive mechanism 23 and the lifting mechanism 21.

[0130] A flexible battery pack support 1112 is provided on the tray mounting area. When the battery pack is placed on the tray 1111, the height of the flexible battery pack support 1112 can be compressed. The rectangular spring is compressed by the lifting of the moving plate, thereby allowing the unlocking member to extend from the through hole of the tray, realizing the push rod 42 inside the battery pack. The push rod pushes the locking mechanism 3 to realize the locking and unlocking of the battery pack. The specific operation process is as follows:

[0131] like Figures 9 to 13 As shown, a locking mechanism 3 is provided on the vehicle's longitudinal beam. The battery pack 4 is detachably connected to the vehicle's longitudinal beam via a hook 41 mounted on its top, which engages with the locking mechanism 3. The locking mechanism 3 includes a primary lock 31, which comprises a primary lock base 311, three primary lock tongues 312, and a locking rod 313. The through slot includes a primary lock groove 314. The primary lock base 311 has a horizontally penetrating, inverted L-shaped primary lock groove 314. The primary lock base 311 and the primary lock tongues 312 are arranged in a one-to-one correspondence. The primary lock base 311 is located on the side wall of the electric vehicle's longitudinal beam. The first end of the primary lock tongue 312 is rotatably connected to the primary lock base 311, and the second end of the primary lock tongue 312 is rotatably connected to the locking rod 313. The hook 2 at each mounting bracket of the electric vehicle's battery pack 4 passes through the primary lock groove 314.

[0132] When the locking link 313 is subjected to the force of the unlocking component, the locking link 313 drives the primary locking tongue 312 to rotate and open the opening of the primary locking groove 314. The hook 41 enters and exits the primary locking groove 314 through the opening of the primary locking groove 314. A push rod 42 is provided in the battery pack 4 at the position corresponding to the locking mechanism 3. The push rod 42 is vertically arranged and can move along the vertical direction.

[0133] When locking: the unlocking component pushes the top rod 42, which in turn pushes the locking linkage 313, thus unlocking the battery pack. The quick-change bracket on the battery pack is then pushed into the inverted L-shaped primary lock groove 314 of the locking mechanism 3, thereby locking the battery pack.

[0134] During unlocking: The battery pack swapping moving assembly 1 moves the battery pack towards the inside of the inverted L-shaped primary lock groove 314 of the locking mechanism 3. The unlocking component pushes the push rod 42, which in turn pushes the locking linkage 313, thus opening the locking mechanism 3. The battery pack swapping moving assembly 1 then moves the battery pack towards the unlocking opening of the L-shaped groove, exiting the vehicle-side locking mechanism 3 and unlocking the battery pack.

[0135] Specifically, the unlocking component on the battery pack swapping moving assembly 1, which carries the battery pack, pushes the push rod 42 upward, causing the push rod 42 to move upward. When the push rod 42 is driven to push upward in the vertical direction, it contacts the locking linkage 313 of the locking mechanism 3 located on the body bracket of the electric vehicle, thereby unlocking the locking mechanism 3 and achieving the unlocking purpose.

[0136] When unlocking component 13 is a torque unlocking lever, the torque unlocking lever can be a torque gun. For example... Figure 14 As shown, the torque gun 131 includes a sleeve device 1311, a power unit 1312, a preload device 1313, and a housing 1314. The upper end of the sleeve device is connected to the locking / unlocking mechanism and can rotate to transmit torque to the locking / unlocking mechanism. The power unit is used to output power to drive the sleeve device to rotate. One end of the preload device abuts against the sleeve device, and the other end abuts against the power unit. The preload device is in a preloaded state and is used to provide an upward preload force to the sleeve device. The lower end of the housing is connected to the power unit, and the upper end of the housing is connected to the sleeve device. The internal space of the housing is used to accommodate a part of the sleeve device and at least a part of the power unit. The power unit and the sleeve device are housed in the same housing, making the structure compact and the layout reasonable. The preload device provides an upward preload force. In the working state, the preload device can continuously provide an upward restoring force. In the non-working state, the preload device can maintain the stability of the sleeve device within a certain force range.

[0137] In this embodiment, the locking mechanism 3 can also be a threaded lock structure. For example... Figure 15As shown, the threaded lock includes a second lock base 32, which has a first opening 321 extending vertically. A first threaded portion 3211, which is an internal thread, is provided within the first opening 321. The battery pack includes a lock connection structure 5 for engaging with the locking mechanism 3 to achieve locking. The lock connection structure 5 includes a mounting base 51 and a first unlocking portion 52. The mounting base 51 has a second opening 511 extending vertically, and the first unlocking portion 52 is vertically disposed within the second opening 511. The first unlocking portion 52 is movable vertically relative to the mounting base 51 and has a second threaded portion 521 that engages with the first threaded portion 3211. By applying torque to a torque gun to rotate the lock connection structure 5, the second threaded portion 521 can engage with the first threaded portion 3211, thereby achieving locking and unlocking of the locking mechanism 3 and the lock connection structure 5.

[0138] In other specific embodiments, the locking mechanism 3 can also be a T-lock structure. For example... Figure 16 As shown, the locking mechanism 3 includes a second lock base 32, which has a third opening 322 extending vertically. A stop portion 323 is provided in the third opening 322. In this embodiment, the third opening 322 is a square hole and the stop portion 323 is formed above the third opening 322. The locking shaft of the lock connection structure 5 includes a second unlocking portion 53 and a limiting portion 54. The upper end of the second unlocking portion 53 is provided with the limiting portion 54. The limiting portion 54 includes a locking rod extending horizontally. The locking rod is a columnar body and is horizontally arranged at the top of the second unlocking portion 53. The locking rod and the second unlocking portion 53 together form a T-shaped structure. By applying torque to the torque gun to drive the lock connection structure 5 to rotate, when the locking rod is at the first angle, the locking rod can pass through the third opening 322 and enter the stop part 323 of the second lock base 32. When the locking rod rotates to the second angle, the locking rod can be restricted in the stop part 323, thereby making the second lock base 32 and the lock connection structure 5 relatively fixed.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
