Description

Technical Field

[0001] This invention relates to the field of electric vehicle battery swapping, and particularly to a vehicle positioning component and a battery swapping shuttle vehicle including the component. Background Technology

[0002] Currently, vehicle exhaust emissions remain a significant contributor to environmental pollution. To address this issue, researchers have developed natural gas vehicles, hydrogen fuel cell vehicles, solar-powered vehicles, and electric vehicles to replace gasoline-powered cars. Among these, electric vehicles hold the most promise. Current electric vehicles primarily fall into two categories: direct-charging and fast-swapping. Due to limitations in charging time and location, many new energy electric vehicles are gradually adopting a fast-swapping battery system for refueling.

[0003] In existing chassis-based battery swapping systems, battery swapping shuttles typically unlock and remove the batteries from the swapping vehicle, place them in the swapping station for charging, and then install the fully charged batteries back into the swapping vehicle. However, during the battery swapping process, the quality of batteries varies between different types of swapping vehicles. For large vehicles, such as heavy or light trucks, the significant weight of the vehicle body and cargo necessitates a high-capacity battery pack to support a range of hundreds of kilometers. Furthermore, the large size and weight of batteries in heavy or light trucks mean that the driving force of a single type of battery swapping shuttle is insufficient to meet the requirements of the shuttle's drive mechanism, causing the batteries on the swapping shuttle to shake during the swapping process. The existing battery swapping shuttle vehicles are relatively large, and different battery swapping vehicles require different swapping spaces. The existing battery swapping shuttle vehicles are relatively large, while the space and height for swapping under the chassis of the battery swapping vehicles are limited, which is increasingly unable to meet the trend of miniaturization of battery swapping vehicles. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of unstable driving force output by the drive mechanism of the battery swapping shuttle and large size of the drive mechanism in the battery swapping process of the existing battery swapping shuttle, and to provide a vehicle body positioning component and a battery swapping shuttle including the component.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

The transmission ends of the driving force of the two sets of first drive components are connected and fixed to the second plate component. The driving directions of the two sets of first drive components are the same.

[0009] A first guide mechanism is disposed on the base, the guide direction of the first guide mechanism is the same as the first direction, and the second plate assembly reciprocates along the first guide mechanism under the drive of the two sets of first drive components, the first direction being the movement direction of the battery pack unlocking.

[0010] In this scheme, using two sets of first drive components can increase the load-bearing capacity of the second plate assembly. The two sets of first drive components are set on both sides of the second plate assembly relative to the first direction, making the movement of the second plate assembly more stable. Compared with the transmission using a single set of first drive components, using two sets of first drive components can also reduce the size of each set of first drive components, which is conducive to reducing the installation space of the first drive components in the battery swapping shuttle, making the space utilization of the first drive components in the battery swapping shuttle more reasonable.

[0011] Preferably, the first guide mechanism and the two sets of first drive components are both disposed below the second plate assembly, and the first guide mechanism is used to support the second plate assembly.

[0018] Preferably, the first guiding mechanism has two sets, each set of the first guiding mechanism includes a guide rail and a sliding part, one end of the sliding part is slidably engaged with the guide rail, and the other end of the sliding part is connected to the second plate assembly.

[0019] In this design, the two sets of first guide mechanisms make the movement of the second plate assembly smoother; through the sliding cooperation of the guide rail and the sliding part, the frictional resistance encountered by the second plate assembly during the movement on the first guide mechanism is small, the movement is smoother, and the movement efficiency is improved.

[0020] Preferably, the two sets of the first drive components are disposed inside the two sets of the first guide mechanisms.

[0021] In this scheme, the two sets of first drive components are located inside the two sets of first guide mechanisms, making reasonable use of the space of the second plate components that are fixed to the battery swapping vehicle, thus reducing the volume of the battery swapping shuttle.

[0033] The two sets of first drive components are disposed on the base, and the two sets of first drive components drive the second frame to reciprocate relative to the base along the first direction. The first frame extends out of the base, and the extension direction of the first frame is parallel to the first direction.

[0034] In this solution, compared to the frames of other types of battery swapping shuttles, the second plate assembly has fewer parts, a simpler assembly process, and higher rigidity. Furthermore, the second plate assembly can avoid interference with other structures of the battery swapping shuttle during its movement, allowing it to interact with electric vehicles in a wider space and meet the battery swapping needs of different types of vehicles.

[0035] Preferably, the second frame is fixed to the first frame by a pad, one end of the pad is fixed to one side of the second frame, and the other end of the pad is fixed to one side of the first frame.

[0036] In this design, the use of spacers saves material for the second frame, reducing costs. The structure formed by the spacers, the second frame, and the first frame can accommodate other components, saving design space.

[0037] Preferably, two pads are provided, and the pads are located at the edge of the first frame.

[0038] In this solution, two pads are provided to ensure the stability and reliability of the connection between the first frame and the second frame. The pads are located at the edge of the first frame and are spaced apart to reduce the overall weight of the first frame and the second frame.

[0041] Preferably, the first frame is provided with a through hole, and the first frame is rectangular, and / or;

[0042] The second frame is rectangular.

[0043] In this design, the first frame is provided with through holes. Under the condition that the stiffness is met, the mass of the first frame can be reduced and the cost can be lowered. The first and second frames are rectangular to maximize the use of the overall design space. The rectangular shape of the second frame ensures the stability of its connection with the guide mechanism.

[0044] Preferably, the projected dimension of the cross section of the first frame in the plane perpendicular to the first direction in the horizontal plane is smaller than the projected dimension of the cross section of the second frame in the plane perpendicular to the first direction in the horizontal plane.

[0045] In this design, the second frame is wider, so the spacing between the guide rails can be set wider, which is beneficial for the smooth movement of the second frame; the first frame is narrower, which is beneficial for collision avoidance.

[0046] Preferably, one end of the first frame is fixed to the second frame, and the other end of the first frame is suspended above the second frame; or,

[0047] The other end of the first frame is slidably connected to the base via a crimping block, and the guiding direction of the crimping block is a first direction.

[0048] In this design, one end of the first frame is mounted on the second frame. The purpose of this is to fix one end of the first frame onto the second frame, while the other end is suspended above the second frame. This is to avoid other structures and to facilitate the cooperation with its corresponding components.

[0049] A battery swapping shuttle vehicle includes a vehicle positioning component as described above, and further includes a battery pack positioning and unlocking component, the battery pack positioning and unlocking component comprising:

[0050] First board assembly;

[0051] An unlocking lever and a positioning element for positioning the battery pack are provided on the first plate assembly.

[0052] The first plate assembly is configured to reciprocate along the first direction.

[0053] In this solution, the battery swapping shuttle includes a vehicle positioning assembly. Using two sets of first drive assemblies increases the load-bearing capacity of the second plate assembly. These two sets of first drive assemblies are positioned on either side of the second plate assembly relative to the first direction, resulting in smoother movement of the second plate assembly. Compared to using a single set of first drive assemblies in a transmission system, using two sets of first drive assemblies reduces the size of each set, thus reducing the installation space required for the first drive assemblies within the battery swapping shuttle and making more efficient use of space. The battery pack positioning and unlocking assembly includes a first plate assembly, an unlocking lever, and a positioning component for positioning the battery pack. The positioning component positions the positioning component on the battery swapping cart against the electric vehicle. The unlocking lever unlocks the battery pack on the electric vehicle, allowing the old battery pack on the electric vehicle to be placed on the first plate assembly, and the battery swapping cart then moves the old battery pack out.

[0054] Preferably, the unlocking lever is a torque unlocking lever, which is used to apply torque to cooperate with the unlocking mechanism to achieve unlocking.

[0055] In this solution, a torque unlocking lever is used to unlock the device. The torque unlocking lever is used to apply torque to cooperate with the unlocking mechanism to achieve unlocking. This unlocking method is simple, fast, and reliable.

[0056] Preferably, the battery swapping shuttle also includes a base, and the battery pack positioning and unlocking assembly also includes a second drive assembly and a second guide member, both of which are disposed on the base, and both the first drive assembly and the first guide mechanism are disposed on the base.

[0057] In this scheme, the first drive component drives the body positioning component to position itself relative to the battery swapping vehicle, and the second drive component drives the battery pack unlocking component to move the battery pack unlocking component to the appropriate position on the battery swapping vehicle and unlock the battery on the battery swapping vehicle. The first drive component and the first guide mechanism are used to move the body positioning component to the vicinity of the electric vehicle.

[0058] Preferably, the battery swapping shuttle further includes a lifting mechanism disposed on the base, the lifting mechanism driving the vehicle positioning component to move up and down to fix the vehicle positioning component to the vehicle body, the lifting mechanism driving the vehicle positioning component and the battery pack positioning and unlocking component to move the battery pack after the battery swapping shuttle is fixed to the vehicle body to unlock the battery pack; and / or, at least a portion of the two sets of first drive components are disposed below the first plate component.

[0059] In this solution, the vehicle positioning component of the battery swapping shuttle can accurately position the battery swapping trolley and the battery swapping vehicle. The lifting mechanism raises the first plate assembly to a suitable height close to the battery swapping vehicle, thereby enabling the battery movement unlocking component to install or remove the battery. At least a portion of the first drive assembly is located below the first plate assembly, saving space on the battery swapping trolley.

[0060] Preferably, the first plate assembly has a second recess for avoidance, and the second plate assembly is at least partially located inside the second recess.

[0061] In this design, the first plate assembly has a second recess, and the second plate assembly is at least partially located inside the second recess to prevent interference between the second plate assembly and the first plate assembly during movement.

[0062] Preferably, the second recess is a groove, the first plate assembly has a battery pack fixing area corresponding to the inner edge of the groove, the battery pack fixing area is provided with the positioning member, the positioning member is a rod-shaped structure, and at least a portion of the first drive assembly is disposed below the battery pack fixing area.

[0063] In this design, the second recess is a groove, which can minimize the space of the first plate assembly. The battery can be placed on the first plate assembly. The battery pack is equipped with positioning components to prevent the battery from moving relative to the first plate assembly. A part of the first drive assembly is located below the fixed area of ​​the battery pack, which can drive the battery smoothly and prevent the battery from shaking during movement.

[0064] Preferably, the first plate assembly has battery tray mounting areas on both sides of the groove, the battery pack fixing area is between the two battery tray mounting areas, the unlocking rod is disposed in the battery tray mounting area, and the second drive assembly and the second guide are disposed below the battery tray mounting area.

[0065] In this solution, the battery pack is supported by a tray in the battery tray mounting area on the first plate assembly to prevent rigid collisions between the battery pack and the first plate assembly, which could damage the battery pack. The unlocking rod is installed in the tray mounting area to ensure that the unlocking rod can trigger the unlocking mechanism on the battery pack, thus improving operating accuracy. The second drive assembly and the second guide are located below the battery tray mounting area, which can save space and reduce costs.

[0066] The positive and progressive effects of this invention are as follows: using two sets of first drive components can increase the load-bearing capacity of the second plate assembly. The two sets of first drive components are arranged on both sides of the second plate assembly relative to the first direction, making the movement of the second plate assembly more stable. Compared with the transmission using a single set of first drive components, using two sets of first drive components can also reduce the size of each set of first drive components, which is beneficial to reducing the installation space of the first drive components in the battery swapping shuttle, making the space utilization of the first drive components in the battery swapping shuttle more reasonable.

[0131] The following preferred embodiment, together with the accompanying drawings, will illustrate the present invention more clearly and completely, but the scope of protection of the present invention should not be limited to this embodiment.

[0132] See Figure 1 As shown, this embodiment provides a battery swapping shuttle vehicle, which includes a vehicle positioning component and a battery pack positioning and unlocking component. The battery pack positioning and unlocking component includes a first plate component 2, an unlocking rod 21, and a positioning member 13 for positioning the battery pack. The positioning member 13 is used to position the positioning member 13 on the battery swapping shuttle vehicle with the electric vehicle. The unlocking rod 21 can unlock the battery pack on the electric vehicle. The first plate component 2 is configured to reciprocate along a first direction, thereby moving the battery pack between the locked position and the unlocked position on the electric vehicle.

[0133] See Figures 1-4As shown, the vehicle positioning assembly includes a base 3 and further includes: a second plate assembly 1, which is used to fix the battery swapping vehicle body; two sets of first drive assemblies 11, which are disposed on both sides of the second plate assembly 1 relative to a first direction, and the transmission ends of the driving force of the two sets of first drive assemblies 11 are connected and fixed to the second plate assembly 1, and the driving directions of the two sets of first drive assemblies 11 are the same; and a first guide mechanism 12 disposed on the base 3, whose guiding direction is the same as the first direction. The second plate assembly 1 moves reciprocally along the first guide mechanism 12 under the drive of the two sets of first drive assemblies 11, and the first direction is the movement direction for locking and unlocking the battery pack. The battery swapping shuttle can drive the battery pack to move relative to the second plate assembly 1 (i.e., relative to the electric vehicle) along the first direction to lock or unlock the battery pack and adjust the position of the battery pack relative to the electric vehicle.

[0134] In this embodiment, using two sets of first drive components 11 can increase the load-bearing capacity of the second plate assembly 1. The two sets of first drive components 11 are arranged on both sides of the second plate assembly 1 relative to the first direction, making the movement of the second plate assembly 1 more stable. Compared with the transmission using a single set of first drive components 11, using two sets of first drive components 11 can also reduce the size of each set of first drive components 11, which is beneficial to reduce the installation space of the first drive components 11 in the battery swapping shuttle, making the space utilization of the first drive components 11 in the battery swapping shuttle more reasonable.

[0135] The first guide mechanism 12 and the two sets of first drive components 11 are both located below the second plate assembly 1. The first guide mechanism 12 is used to support the second plate assembly 1.

[0136] In this embodiment, the first drive component 11 is disposed below the second plate component 1, thereby facilitating its fixation with the battery swapping vehicle; the first guide mechanism 12 is disposed below the second plate component 1, serving both as a guide and support for the second plate component 1.

[0137] Each first drive assembly 11 includes a driver 111, a power output shaft 112, and a transmission part 113. The power output shaft 112 is fitted with the transmission part 113 and threadedly engaged with the transmission part 113. The transmission part 113 is connected to the second plate assembly 1. The driver 111 is used to drive the power output shaft 112 to rotate. The first drive assembly 11 is disposed on the base 3.

[0138] In this embodiment, the driver 111 drives the power output shaft 112 to rotate, and the transmission part 113 converts the rotational motion of the power output shaft 112 into linear motion of the transmission part 113 along the axial direction of the power output shaft 112. The transmission part 113 is connected to the second plate assembly 1, ensuring the moving efficiency and moving stability of the second plate assembly 1.

[0139] The first guide mechanism 12 has two sets. Each set of the first guide mechanism 12 includes a guide rail 121 and a sliding part 122. One end of the sliding part 122 is slidably engaged with the guide rail 121, and the other end of the sliding part 122 is connected to the second plate assembly 1.

[0140] In this embodiment, the arrangement of two sets of first guide mechanisms 12 makes the movement of the second plate assembly 1 more stable; through the sliding cooperation of the guide rail 121 and the sliding part 122, the frictional resistance encountered by the second plate assembly 1 during the movement on the first guide mechanism 12 is small, the movement is smoother, and the movement efficiency is improved.

[0141] See Figure 2 and Figure 4 As shown, the two sets of first drive components 11 are disposed inside the two sets of first guide mechanisms 12.

[0142] In this embodiment, two sets of first drive components 11 are disposed inside two sets of first guide mechanisms 12, which makes reasonable use of the space of the second plate component 1 that is fixed to the battery swapping vehicle, thereby reducing the volume of the battery swapping shuttle.

[0143] The guide rail 121 is set along the travel direction of the battery swapping vehicle, and the guide rail 121 extends from one side of the battery swapping shuttle to the opposite side of the battery swapping shuttle.

[0144] In this embodiment, the guide rail 121 extends from one side of the battery swapping shuttle to the opposite side of the battery swapping shuttle, so that the travel between the starting point and the ending point of the movement of the second plate assembly 1 is large, which makes it easier to adapt to different types of battery swapping vehicles.

[0145] The first guide mechanism 12 also includes a guide rail mounting base 123, on which the guide rail 121 is fixedly connected.

[0146] In this embodiment, the guide rail mounting base 123 makes the installation of the guide rail 121 more secure, further ensuring the stability of the moving plate running on the first guide mechanism 12.

[0147] The second plate assembly 1 is provided with a positioning component 13, which is used to insert into the corresponding positioning hole of the battery swapping vehicle.

[0148] In this embodiment, the positioning member 13 can be inserted into the positioning hole in the battery pack, ensuring the stability of the battery pack during movement and lifting.

[0149] The second plate assembly 1 is provided with two sets of positioning parts 13, which are located on both sides of the second plate assembly 1.

[0150] In this embodiment, two sets of positioning components 13 are provided to ensure the accuracy and stability of the mutual positioning between the battery swapping vehicle and the second plate assembly 1.

[0151] It also includes a limit position detection device 14 and an origin detection device 15. The limit position detection device 14 is used to detect whether the second plate assembly 1 has reached a preset position, and the origin detection device 15 is used to detect whether the second plate assembly 1 is located at the origin position. The origin detection device 15 is located on the guide rail 121. When the sensing device on the second frame 17 detects the limit position sensor and the sensor on the origin detection device 15, it transmits the above-mentioned electrical signals to the corresponding driver 111, thereby improving the motion control accuracy of the driver 111 for the second plate assembly 1.

[0152] In this embodiment, the limit position detection device 14 can detect whether the second plate assembly 1 has reached the preset position, ensuring the accuracy of the movement of the second plate assembly 1, thereby ensuring the accuracy of the battery pack movement and improving the battery swapping efficiency; the origin detection device 15 is used to detect whether the second plate assembly 1 is located at the origin position. When the second plate assembly 1 needs to be reset, the origin detection device 15 can be used to determine whether the reset is completed, improving the reset accuracy of the vehicle positioning assembly used for placing and moving the battery pack.

[0153] The second plate assembly 1 includes a first frame 16 and a second frame 17 stacked together, with the first frame 16 and the second frame 17 being relatively fixed to each other;

[0154] Two sets of first drive components 11 are disposed on the base 3. The two sets of first drive components 11 drive the second frame 17 to reciprocate relative to the base 3 along the first direction. The first frame 16 extends out of the base 3, and the extension direction of the first frame 16 is parallel to the first direction.

[0155] In this embodiment, compared with the frames of other types of battery swapping shuttles, the second plate assembly 1 of this solution has fewer parts, a simpler assembly process, and higher rigidity. Furthermore, the second plate assembly 1 can avoid other structures of the battery swapping shuttle during its movement, ensuring that its movement does not interfere with other structures. It can interact with electric vehicles in a wider space, meeting the battery swapping needs of different types of vehicles.

[0156] The second frame 17 is fixed to the first frame 16 by a pad 171. One end of the pad 171 is fixed to one side of the second frame 17, and the other end of the pad 171 is fixed to one side of the first frame 16.

[0157] In this embodiment, the pad 171 saves material for the second frame 17 and reduces costs. The structure formed by the pad 171, the second frame 17, and the first frame 16 can accommodate other components, saving design space.

[0158] Two pads 171 are provided, and the pads 171 are located at the edge of the first frame 16.

[0159] In this embodiment, two pads 171 are provided to ensure the stability and reliability of the connection between the first frame 16 and the second frame 17. The pads 171 are located on the side of the first frame 16 and are spaced apart, which reduces the overall weight of the first frame 16 and the second frame 17.

[0160] Along the first direction, the end of the second frame 17 has a first recess 18 for avoidance, the first recess 18 being a groove.

[0161] In this embodiment, the second frame 17 is provided with a first recess 18 so that the second frame 17 avoids other structures during movement. The first recess 18 is a groove, which can avoid other mechanical structures to the greatest extent.

[0162] The first frame 16 is provided with a through hole 161, and the first frame 16 is rectangular, and / or;

[0163] The second frame 17 is rectangular.

[0164] In this embodiment, the first frame 16 is provided with a through hole 161. Under the condition that the rigidity meets the requirements, the mass of the first frame 16 can be reduced and the cost can be reduced. The first frame 16 and the second frame 17 are rectangular, which maximizes the use of the overall design space. The rectangular shape of the second frame 17 ensures the stable connection between it and the guide mechanism.

[0165] The projected dimension of the cross-section of the first frame 16 in the plane perpendicular to the first direction is smaller than the projected dimension of the cross-section of the second frame 17 in the plane perpendicular to the first direction. That is, the width of the first frame 16 is smaller than the width of the second frame 17.

[0166] In this embodiment, the second frame 17 is wider, so the spacing of the guide rails 121 can be set wider, which is conducive to the smooth movement of the second frame 17; the first frame 16 is narrower, which is conducive to collision avoidance.

[0167] One end of the first frame 16 is fixed to the second frame 17, and the other end of the first frame 16 is suspended above the second frame 17; or,

[0168] The other end of the first frame 16 is slidably connected to the base 3 by a pressing block, and the guiding direction of the pressing block is the first direction.

[0169] In this embodiment, one end of the first frame 16 is disposed on the second frame 17. The purpose is to fix one end of the first frame 16 on the second frame 17, while the other end is suspended above the second frame 17. This is to avoid other structures and to facilitate cooperation with its corresponding components.

[0170] The battery pack positioning and unlocking assembly also includes a second drive assembly 23 and a second guide 24, both of which are mounted on the base 3. The first drive assembly 11 and the first guide mechanism 12 are both mounted on the base 3.

[0171] In this embodiment, the first drive component 11 drives the vehicle body positioning component to position itself relative to the battery swapping vehicle, and the second drive component 23 drives the battery pack unlocking component to move to the appropriate position on the battery swapping vehicle and unlock the battery on the battery swapping vehicle. The first drive component 11 and the first guide mechanism 12 are used to move the vehicle body positioning component to the vicinity of the electric vehicle.

[0172] The battery swapping shuttle also includes a lifting mechanism mounted on the base 3. The lifting mechanism drives the body positioning component to move up and down to fix the body positioning component to the body. The lifting mechanism drives the body positioning component and the battery pack positioning and unlocking component to move up and down to fix the battery swapping shuttle to the body and then move the battery pack to unlock the battery pack.

[0173] In this embodiment, the body positioning component of the battery swapping shuttle can accurately position the battery swapping trolley and the battery swapping vehicle. The lifting mechanism lifts the first plate component 2 to an appropriate height close to the battery swapping vehicle, thereby enabling the battery movement unlocking component to install or remove the battery.

[0174] At least a portion of the two sets of first drive components 11 are disposed below the first plate component 2.

[0175] In this embodiment, at least a portion of the first drive component 11 is disposed below the first plate component 2, saving space for the battery swapping vehicle.

[0176] The first plate assembly 2 has a second recess 25 for avoidance, and the second plate assembly 1 is at least partially located inside the second recess 25.

[0177] In this embodiment, the first plate assembly 2 has a second recess 25, and the second plate assembly 1 is at least partially located inside the second recess 25 to prevent interference between the second plate assembly 1 and the first plate assembly 2 during movement.

[0178] The second recess 25 is a groove, and the first plate assembly 2 has a battery pack fixing area corresponding to the inner edge of the groove. The battery pack fixing area is provided with a positioning member 13, which is a rod-shaped structure. At least a part of the first drive assembly 11 is disposed below the battery pack fixing area.

[0179] In this embodiment, the second recess 25 is a groove, which can minimize the space of the first plate assembly 2. The battery can be placed on the first plate assembly 2. The battery pack is provided with a positioning member 13 to prevent the battery from moving relative to the first plate assembly 2. A part of the first driving component 11 is disposed below the fixed area of ​​the battery pack, which can drive the battery smoothly and prevent the battery from shaking during movement.

[0180] The first plate assembly 2 has battery tray 22 mounting areas on both sides of the groove, and the battery pack fixing area is between the two battery tray 22 mounting areas. The unlocking rod 21 is set in the battery tray 22 mounting area, and the second drive assembly 23 and the second guide 24 are set below the battery tray 22 mounting area.

[0181] In this embodiment, the battery pack is supported by the tray 22 in the battery tray 22 mounting area on the first plate assembly 2 to avoid rigid collision between the battery pack and the first plate assembly 2, which would cause damage to the battery pack. The unlocking rod 21 is installed in the tray 22 mounting area to ensure that the unlocking rod 21 can trigger the unlocking mechanism on the battery pack, thereby improving the operating accuracy. The second drive assembly 23 and the second guide 24 are located below the battery tray 22 mounting area, which can save space and reduce costs.

[0182] In this embodiment, the unlocking component is a pin, which can trigger the top rod of the battery pack, causing the top rod of the battery pack to trigger the unlocking linkage in the battery swapping vehicle. The unlocking linkage further triggers the locking mechanism of the body bracket 600 on the battery swapping vehicle used to install the battery pack, thereby unlocking or locking the battery pack.

[0183] The battery swapping shuttle also includes a lifting mechanism connected to the base 3, which is used to raise and lower the base 3. The raising and lowering of the base 3 causes the first plate assembly to rise and fall, allowing the battery pack on the first plate assembly to be installed on the battery swapping vehicle, or to be removed from the battery swapping vehicle and placed on the first plate assembly. An unlocking mechanism is used to unlock the battery pack from the battery swapping vehicle when the battery pack is lifted. The lifting mechanism is capable of vertically moving the base.

[0184] Accordingly, such as Figure 5 As shown, the locking mechanism of the vehicle body bracket 600 includes a first lock base 610. The first lock base 610 has a lock groove 612 for the locking shaft on the battery pack to enter and lock. At least a portion of the locking tongue 613 is inserted into the lock groove 612 to prevent the locking shaft from leaving the lock groove 612. One end of the locking tongue 613 is rotatably disposed within the first lock base 610, and the other end of the locking tongue 613 is connected to a locking linkage 620. The locking linkage 620 is used to rotate the locking tongue 613 between an unlocked state and a locked state under the action of an unlocking driving force, thereby opening or closing the opening 611 for the locking shaft to enter and exit the lock groove 612. The opening 611 is a flared shape to facilitate the entry of the battery pack's locking shaft into the lock groove 612.

[0185] like Figures 6 to 7 As shown, the battery pack 700 has a mounting bracket 710 at its upper end, and a hook-and-loop fastener 711 is provided on the mounting bracket 710. The locking shaft is the hook-and-loop fastener 711 on each mounting bracket 710 of the battery pack 700. The hook-and-loop fastener 711 is located at the top of the battery pack 700 corresponding to the locking mechanism position on the body bracket 600 of the battery swapping vehicle. The battery pack 700 is locked by inserting the hook-and-loop fastener 711 into the locking groove 612 of the locking mechanism. A push rod 720 is provided inside the battery pack 700 at the position corresponding to the locking mechanism. The push rod 720 is used to push up the locking linkage 620 of the locking mechanism.

[0186] In other embodiments, the unlocking element can also be a torque unlocking element, which applies torque to cooperate with the locking mechanism to achieve locking and unlocking. In this case, the unlocking element can be a torque gun. Figure 8 As shown, the torque gun 800 includes a sleeve device 810, a power unit 820, a preload device 830, and a housing 840. The upper end of the sleeve device 810 is connected to the locking mechanism of the battery pack and is rotatable to transmit torque to the locking mechanism. The power unit 820 is used to output power to drive the sleeve device 810 to rotate. One end of the preload device 830 abuts against the sleeve device 810, and the other end abuts against the power unit 820. The preload device 830 is in a preloaded state and is used to provide an upward preload force to the sleeve device 810. The lower end of the housing 840 is connected to the power unit 820, and the upper end of the housing 840 is connected to the sleeve device 810. The internal space of the housing 840 is used to accommodate a part of the sleeve device 810 and at least a part of the power unit 820. The power unit 820 and the sleeve device 810 are housed in the same outer casing 840, making the structure compact and the layout reasonable. The preload device 830 provides an upward preload force. In the working state, the preload device 830 can continuously provide an upward restoring force. In the non-working state, the preload device 830 can maintain the stability of the sleeve device 810 within a certain force range.

[0187] When the locking mechanism is a threaded lock, an external thread is provided on the outer circumference of the unlocking rod. When unlocking is required, the unlocking rod drives the external thread to move, thereby unlocking the mechanism by engaging with the internal thread on the locking mechanism. Figure 9As shown, the locking mechanism includes a second lock base 640, which has a first opening 641 extending vertically. A first threaded portion 642, which is an internal thread, is provided within the first opening 641. The battery pack includes a first lock connection structure 730 for engaging with the second lock base 640 to achieve locking. The first lock connection structure 730 includes a mounting base 731 and an unlocking portion 732. A second opening 733 extending vertically is provided within the mounting base 732. The unlocking portion 732 is vertically disposed within the second opening 733 and is movable vertically relative to the mounting base 731. The unlocking portion 732 has a second threaded portion 734 that engages with the first threaded portion 642. By applying torque to a torque gun to rotate the lock connection structure 730, the second threaded portion 734 can engage with the first threaded portion 642, thereby achieving locking and unlocking of the second lock base 640 and the lock connection structure 730.

[0188] When the locking mechanism is a T-lock, the top of the unlocking lever has a horizontal bar. This horizontal bar is fixedly connected to the body of the unlocking lever, forming a T-shaped structure. Rotation of the unlocking lever causes the horizontal bar to change angle. When the angle of the horizontal bar matches the opening angle on the T-lock, the horizontal bar disengages from the opening, thus unlocking the locking mechanism. Figure 10 As shown, the locking mechanism includes a third lock base 650, which has a second opening 651 extending vertically. A stop portion 652 is provided within the second opening 651. In this embodiment, the second opening 651 is a square hole, and the stop portion 652 is formed above the second opening 651. The battery pack includes a second lock connection structure 740, which includes a fifth transmission part 741. A locking part 742 is provided at the upper end of the fifth transmission part 741. The locking part 742 includes a locking rod extending horizontally. The locking rod is a columnar body and is horizontally positioned at the top of the fifth transmission part 741. The locking part 742 and the fifth transmission part 741 together form a T-shaped structure. By applying torque to the torque gun to drive the second locking connection structure 740 to rotate, when the locking part 742 is at the first angle, the locking rod can pass through the second opening 651 and enter the stop part 652 of the third lock base 650. When the locking part 742 rotates to the second angle, the locking rod can be restricted in the stop part 652, thereby fixing the locking mechanism and the second locking connection structure 740 relative to each other.

[0189] The aforementioned structure and unlocking method make it suitable for various unlocking environments.
