[0002] Battery-powered mobile devices, such as drones, electric vehicles, and electric cars, require convenient and quick battery replacement in certain situations. For example, in scenarios where drones are used to inspect trains, the drone needs to have its battery replaced after a period of inspection before continuing the inspection. To improve inspection efficiency, rapid battery replacement is necessary.

[0003] Therefore, how to develop a battery replacement device that can quickly replace the battery of an electric mobile device has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a battery replacement device that can quickly replace the battery of an electric mobile device, and requires fewer mobile devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model discloses a battery replacement device for installing and removing batteries from an electric mobile device. It is characterized by comprising a frame, on which a docking platform, a charging device, a clamping device, a first moving device for moving the docking platform and the clamping device along a first direction, and a second moving device for moving the charging device; the first direction is the longitudinal direction of the frame; it also includes a first connecting structure for connecting and disconnecting the first moving device from the docking platform, a second connecting structure for connecting and disconnecting the docking platform from the frame, and a second limiting structure for limiting the electric mobile device.

[0007] The clamping device is disposed on the first moving device, and the clamping device includes a clamping structure for clamping the battery and an unlocking structure for unlocking and locking the first locking structure of the battery.

[0008] The charging device includes a charging rack with at least two charging positions. The second moving device moves the charging rack to a position where the desired charging position is directly opposite the clamping device along the first direction. The charging position is provided with a first charging electrode, a supporting structure for supporting the battery, a first limiting structure for cooperating with the first locking structure to lock the battery, and a space for the clamping device to pass through along the first direction. When the clamping device clamps the battery and moves it to a preset position of the charging position along the first direction, the second charging electrode of the battery is connected to the first charging electrode.

[0009] The first mobile device drives the docking platform to a first position for battery installation and removal of the electric mobile device and a second position for docking and departure of the electric mobile device.

[0010] Optionally, the first connection structure includes two opposing first limiting slots disposed on the docking platform, and two locking blocks disposed on the first moving device that move relative to each other along a second direction, the second direction being the transverse direction of the frame.

[0011] Optionally, the second connection structure includes a second limiting slot disposed on the docking platform and a telescopic block disposed on the frame.

[0012] Optionally, the unlocking structure and the clamping structure are the same structure. The clamping structure includes two oppositely arranged clamping members that move along a second direction and a driving structure for driving the clamping members to move. The second direction is the lateral direction of the frame.

[0013] Optionally, the first connection structure includes two opposing first limiting slots disposed on the docking platform and two locking blocks disposed on the clamping member, wherein the locking blocks cooperate with the first limiting slots.

[0014] Optionally, the second connection structure includes the two opposing first limiting slots, a telescopic block on the frame that is driven by elastic force and moves vertically, a first inclined surface on the docking platform for compressing the telescopic block when the docking platform moves in the first direction, and a second inclined surface on the latching block for compressing the telescopic block when the latching block moves in the second direction. When the telescopic block extends into the first limiting slot, the first limiting slot has space for the second inclined surface to extend into and compress the telescopic block.

[0015] Optionally, the second connection structure includes the two opposing first limiting slots, a telescopic block disposed on the frame and driven by elastic force to move along the second direction, and a first inclined surface disposed on the docking platform for compressing the telescopic block when the docking platform moves along the first direction; the first limiting slot is a through slot along the second direction.

[0016] Optionally, the first mobile device is further provided with a battery tray for supporting the battery.

[0017] Optionally, the second limiting structure includes a guide positioning part disposed on the frame for contacting the electric motor to adjust the orientation of the electric motor during the process of the docking platform moving to the first position, and a thrust part disposed on the docking platform for preventing the electric motor from moving away from the charging device in the first direction, wherein the guide positioning part is adapted to the first positioning part of the electric motor.

[0018] Optionally, the second moving device is a translational device, and the charging position includes a guide groove extending along the first direction and having a supporting surface. The guide groove is provided with a limiting groove that is concave to the outside. A fixing plate is connected to one end of the guide groove away from the docking platform, and the first charging electrode is provided on the fixing plate. The guide groove forms the supporting structure, and the limiting groove forms the first limiting structure.

[0019] In this utility model, the battery replacement device includes a docking platform, a charging device, and a clamping device. The charging device has a space for the clamping device to pass through. A first moving device can drive the clamping device to move along a first direction through the charging device, thereby removing the battery from the electric motor. The battery is then moved along the first direction to the charging device for charging, and the charged battery is removed from the charging device and moved to the docking platform for installation on the electric motor. The charging device has at least two charging positions. A second moving device can drive the charging positions to move along a plane perpendicular to the first direction. Thus, when removing the battery, the empty charging position can be aligned with the clamping device; when installing the battery, the charging position containing the battery can be aligned with the clamping device to complete the battery removal and installation. During this process, the clamping device only needs to move back and forth in the first direction to complete the battery removal and installation, the transportation of the battery between the charging device and the docking platform, and the removal and installation of the battery on the charging device. The removal and installation actions are relatively simple and quick, allowing for rapid battery replacement of the electric motor. Furthermore, through the arrangement of the first and second connecting structures, and the structural design of placing the clamping device on the first moving device, the first moving device alone can both drive the docking platform to move and drive the clamping device to install and remove the battery, thus reducing the setup and use of the moving device.

Detailed Implementation

[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this invention. Rather, they are merely examples of apparatuses or methods consistent with some aspects of this invention.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0038] See Figure 1-13 This utility model provides a battery replacement device for installing and removing batteries from an electric mobile device. It includes a frame 1, which can refer to a fixed surface of a building, such as a wall or floor. Alternatively, it can refer to a support structure for placing or fixing the device in a specific location, such as a box or bracket. See also... Figure 1 The frame 1 is equipped with a docking platform 2, a charging device 4, and a clamping device 3; a first moving device 5 for moving the docking platform 2 and the clamping device 3 along a first direction; and a second moving device 6 for moving the charging device 4. The first direction is the longitudinal direction of the frame 1. Figure 1 The center represents the left-right direction. See also... Figure 6 and 7 It also includes a first connection structure 7 for connecting and disconnecting the first moving device 5 from the docking platform 2, and a second connection structure 8 for connecting and disconnecting the docking platform 2 from the frame 1. It also includes a second limiting structure for limiting the electric moving device. See [link to relevant documentation] Figure 2 The clamping device 3 is disposed on the first moving device 5. The clamping device 3 includes a clamping structure 31 for clamping the battery and an unlocking structure for unlocking and locking the first locking structure of the battery. See also Figure 8The charging device 4 includes a charging rack 41 with at least two charging positions 411. A second moving device 6 moves the charging rack 41 to a position where the desired charging position 411 is directly opposite the clamping device 3 along a first direction. Each charging position 411 is provided with a first charging electrode 4114, a supporting structure for supporting the battery, a first limiting structure for cooperating with a first locking structure to lock the battery, and a space for the clamping device 3 to pass through along the first direction. When the clamping device 3 clamps the battery and moves it along the first direction to a preset position of the charging position 411, the second charging electrode of the battery is connected and conductive to the first charging electrode 4114. The first moving device 5 moves the docking platform 2 to a first position for battery installation and removal of the electric motor and a second position for docking and departure of the electric motor.

[0039] The docking platform 2 can be slidably mounted on the frame 1 in a horizontal direction via a sliding rail structure. A second limiting structure prevents the electric motor from moving relative to the docking platform 2 in the first direction. The electric motor can be a drone, electric car, or electric vehicle. When the electric motor is docked on the docking platform 2, the platform supports it. The battery has clamping spaces on both sides, so the battery does not support the motor. The rest of the motor, except for the battery, contacts the docking platform 2 to support it, ensuring that battery installation and removal do not affect the docking. For example, the battery can be suspended, or although it contacts the platform 2, it does not provide support. When the electric motor is a drone, some drones have a support frame underneath, and the battery is located at the bottom of the drone. The support frame supports the drone, and the battery is suspended. In this case, the structure of the docking platform 2 is not restricted. The clamping device 3 includes a clamping structure 31 and an unlocking structure. The clamping structure 31 is used to connect to the battery, specifically clamping it onto two sides of the battery. The unlocking structure is used to unlock or lock the battery's first locking structure. When the first locking structure on the battery is locked, the battery can be locked inside the battery compartment of the electric motor. When the unlocking structure unlocks the first locking structure, the battery can be moved along the first direction to be removed from the battery compartment, or it can be moved along the first direction to be installed into the battery compartment. The first moving device 5 is used to drive the docking platform 2 or the clamping device 3 to move along the first direction.

[0040] See Figure 10The charging device 4 includes a charging rack 41, which includes at least two charging positions 411. A second moving device 6 is used to move the charging rack 41 so that the charging rack 41 is positioned so that the desired charging position 411 is directly opposite the clamping device 3 along a first direction. Specifically, the second moving device 6 can move the charging rack 41 along a plane perpendicular to the first direction, that is, it can move the charging rack 41 in a vertical plane, specifically through translation or rotation; it can also move the charging rack 41 along a horizontal plane, specifically through translation or rotation. Translation here includes both linear and curved movement. It is sufficient to ensure that the second moving device 6 can align the desired charging position 411 with the clamping device 3 along the first direction, while simultaneously offsetting the unwanted charging position 411 from the clamping device 3.

[0041] Each charging position 411 may be provided with a first charging electrode 4114, a supporting structure for supporting the battery, a first limiting structure for cooperating with a first locking structure to lock the battery, and a space for the clamping device to pass through in a first direction. When the clamping device 3 clamps the battery and moves it to a preset position in the charging position 411 in the first direction, that is, when the battery is correctly installed in the charging position 411, the second charging electrode of the battery connects and conducts with the first charging electrode 4114. The specific setting of the first charging electrode 4114 is not limited, as long as the condition that the battery only needs to move into the charging position 411 in the first direction and reach the preset position, and the second charging electrode on the battery connects and conducts with the first charging electrode 4114 to enable charging is met. For example, the first charging electrode 4114 may be set on the surface of the charging position 411 opposite to the battery in the first direction, or it may be set on the surface of the charging position 411 opposite to the top or bottom of the battery. Figure 10 The diagram shows the first charging electrode 4114 disposed on the surface of the charging position 411 opposite to the battery in the first direction.

[0042] See Figure 2 The first moving device 5 can be a linear module, including a first slide rail 51 and a first slider 52, and the clamping device 3 can be mounted on the first slider 52. Alternatively, the first moving device 5 can also be a telescopic cylinder or similar structure. The second moving device 6 has a similar structure to the first moving device 5 and will not be described further. The following description uses the example of the first moving device 5 and the second moving device 6 being linear modules.

[0043] Battery disassembly and assembly process: Disassemble the battery, see [link to documentation]. Figure 1The first moving device 5 is connected to the docking platform 2 via the first connecting structure 7, and the second connecting structure 8 is disconnected to detach the docking platform 2 from the frame 1. The first moving device 5 drives the docking platform 2 to extend, that is, to move the docking platform 2 to the second position along the first direction. The electric moving device docks on the docking platform 2, and then the first moving device 5 drives the docking platform 2 to retract, that is, to move the docking platform 2 to the first position along the first direction. Under the limiting action of the second limiting structure, the electric moving device will move along the docking platform 2 along the first direction. After the docking platform 2 moves to the first position, the frame 1 is connected to the docking platform 2 via the second connecting structure 8, thereby fixing the docking platform 2. Under the action of the second limiting structure, the electric moving device is fixed along with the docking platform 2. The first connecting structure 7 is disconnected to detach the first moving device 5 from the docking platform 2. It should be noted that the order of the actions of the second connecting structure 8 and the docking platform 2, or the first connecting structure 7 and the docking platform 2, is not specifically limited. The order can be determined according to the specific structure, or the two can be performed simultaneously. The second moving device 6 drives the charging rack 41 to move along the second direction, so that the empty charging position 411 is aligned with the clamping device 3. The first moving device 5 drives the clamping device 3 from right to left (with the position of the docking platform 2 on the longitudinal direction of the frame 1 as the left side) through the empty charging position 411, and reaches the position of the battery of the electric motor on the docking platform 2. The clamping device 3 clamps the two sides of the battery, and the first locking structure of the battery is unlocked by the unlocking structure. The battery is pulled out from left to right, and then continues to move to the right into the empty charging position 411. After moving into position, the second charging electrode of the battery is connected to the first charging electrode 4114 to conduct electricity and start charging. The unlocking structure locks the first locking structure at the first limiting structure on the charging position 411. The clamping device 3 releases the battery and continues to move to the right, moving back to the right side of the charging device 4.

[0044] The battery is loaded. The second moving device 6 moves the charging rack 41, moving the charging position 411 with the charged battery to a position opposite to the clamping device 3. The first moving device 5 moves the clamping device 3 from the right side of the charging position 411, clamping the two sides of the battery. The unlocking mechanism unlocks the first locking structure and the first limiting structure, allowing the battery to be removed from the charging position 411 in the first direction. The clamping device 3, holding the battery, moves to the left until it reaches the position of the electric motor mover, pushing the battery into the battery compartment of the electric motor mover. After installation, the unlocking structure locks the first locking structure, locking the battery in the battery compartment. The clamping device 3 releases the battery, completing the battery loading.

[0045] This battery replacement device includes a docking platform 2, a charging device 4, and a clamping device 3. The charging device 4 has a space for the clamping device 3 to pass through. A first moving device 5 can drive the clamping device 3 to move along a first direction through the charging device 4, thereby removing the battery from the electric motor. The battery is then moved along the first direction to the charging device 4 for charging, and the charged battery is removed from the charging device 4 and moved to the docking platform 2 for installation on the electric motor. The charging device 4 has at least two charging positions 411. A second moving device 6 can drive the charging positions 411 to move along a plane perpendicular to the first direction. Thus, when removing the battery, the empty charging position 411 can be aligned with the clamping device 3, and when installing the battery, the charging position 411 with the battery is aligned with the clamping device 3 to complete the battery removal and installation. During this process, the clamping device 3 only needs to move back and forth in the first direction to complete the battery removal and installation, the transportation of the battery between the charging device 4 and the docking platform 2, and the removal and installation of the battery on the charging device 4. The disassembly and assembly operations are relatively simple and quick, allowing for rapid battery replacement of the electric motor. Furthermore, the design of the first connecting structure 7 and the second connecting structure 8, along with the clamping device 3 mounted on the first moving device 5, allows the first moving device 5 to simultaneously move the docking platform 2 and the clamping device 3 for battery installation and removal, reducing the need for additional moving devices.

[0046] Optionally, the detachment Figure 2-7 The first connecting structure 7 includes two opposing first limiting slots 71 disposed on the docking platform 2, and two locking blocks 72 disposed on the first moving device 5 that move relative to each other along a second direction, the second direction being the lateral direction of the frame 1. Specifically, the two locking blocks 72 are slidably disposed on the first slider 52, and each locking block 72 is provided with a corresponding driving structure. The driving structure is used to drive the two locking blocks 72 to move relative to each other. When the first connecting structure 7 needs to be connected, the two locking blocks 72 move away from each other and enter the two first limiting slots 71 respectively, forming a locking; when the first connecting structure 7 needs to be disconnected, the two locking blocks 72 move closer to each other and disengage from the two first limiting slots 71 respectively.

[0047] Optionally, the second connection structure 8 includes a second limiting slot 81 disposed on the docking platform 2 and a telescopic block 82 disposed on the frame 1.

[0048] See Figure 4-7The telescopic locking block 82 can be a telescopic locking block 82 that moves vertically. The second limiting slot 81 can be the same structure as the first limiting slot 71 or a different structure. When the second connecting structure 8 needs to be connected, the telescopic locking block 82 can be provided with a corresponding driving structure. The driving structure drives the telescopic locking block 82 to move vertically into the second limiting slot 81, forming a locking connection. When the second connecting structure 8 needs to be disconnected, the driving structure drives the telescopic locking block 82 to move vertically out of the second limiting slot 81.

[0049] Optionally, see Figure 8 and 9 The telescopic block 82 can also be along the second direction ( Figure 9 The telescopic locking block 82 moves in the vertical direction. The second limiting slot 81 can be the same structure as the first limiting slot 71 or a different structure. The telescopic locking block 82 can be provided with a corresponding driving structure. The driving structure drives the telescopic locking block 82 to move in the second direction into the second limiting slot 81 to form a locking connection. When the second connecting structure 8 needs to be disconnected, the driving structure drives the telescopic locking block 82 to move out of the second limiting slot 81 in the second direction.

[0050] Optionally, the unlocking structure and the clamping structure 31 are the same structure, see [link to relevant documentation]. Figure 2-3 The clamping structure 31 includes two opposing clamping members 311 that move along a second direction, and a driving structure 312 for driving the clamping members 311 to move. The second direction is the lateral direction of the frame 1. The driving structure 312 drives the two clamping members 311 to move closer or further apart, thereby completing the clamping and opening. The clamping device 3 unlocks the first locking structure while clamping the battery, and locks the first locking structure while releasing the battery. Setting the unlocking structure and the clamping structure 31 as the same structure is simple in structure, and the clamping process and the unlocking process are realized by one action, and the releasing process and the locking process are realized by one action, which can further reduce the battery replacement time. The battery compartment of the electric motor can be provided with a guide and limiting structure similar to the charging position 411. The specific unlocking and locking process is described below.

[0051] Optionally, see Figure 2-7 The first connecting structure 7 includes two opposing first limiting slots 71 disposed on the docking platform 2 and two engaging blocks 72 disposed on the clamping member 311. The engaging blocks 72 cooperate with the first limiting slots 71. Specifically, a connecting rod 23 can be disposed on the inner slide rail of the docking platform 2, and the bottom of the connecting rod 23 can be provided with the first limiting slots 71. By placing the engaging blocks 72 on the clamping member 311, the engaging blocks 72 and the clamping member 311 can share a single driving structure, reducing the number of driving structures required. See also... Figure 3The snap-fit ​​block 72 is connected to the clamping member 311 by a rod extending along the first direction.

[0052] Optionally, see Figure 2-7 The second connecting structure 8 includes two opposing first limiting slots 71, a telescopic block 82 mounted on the frame 1 and driven by elastic force to move vertically, a first inclined surface 231 mounted on the docking platform 2 to compress the telescopic block 82 when the docking platform 2 moves in the first direction, and a second inclined surface 721 mounted on the locking block 72 to compress the telescopic block 82 when the locking block 72 moves in the second direction. When the telescopic block 82 extends into the first limiting slot 71, the first limiting slot 71 leaves space for the second inclined surface 721 to extend into and compress the telescopic block 82.

[0053] Thus, the first limiting slot 71 can serve as part of both the first connecting structure 7 and the second connecting structure 8. Specifically, the first limiting slot 71 can be located at the bottom of the connecting rod 23. The first limiting slot 71 has an opening in the horizontal direction and an opening at the bottom. A first inclined surface 231 is provided on the side of the first limiting slot 71 in the first direction. The first inclined surface 231 gradually slopes vertically along the first direction. A second inclined surface 721 is provided at the bottom of the locking block 72. The second inclined surface 721 gradually slopes vertically along the second direction.

[0054] When the first connecting structure 7 needs to be connected, the driving structure 312 drives the clamping member 311 and causes the two locking blocks 72 to move away from each other, and the locking blocks 72 are locked into the first limiting slot 71.

[0055] When the second connecting structure 8 is required for connection, the first moving device 5 drives the docking platform 2 to the right along the first direction ( Figure 1 When the docking platform 2 (located on the left) moves, the first inclined surface 231 will contact and gradually press down on the telescopic block 82. When the first limiting slot 71 moves to the position of the telescopic block 82, the telescopic block 82 will abut against the bottom of the locking block 72. When the two locking blocks 72 move close to each other, the locking block 72 will disengage from the first limiting slot 71. At the same time, the telescopic block 82 will gradually contact the second inclined surface 721 under the action of elastic force and extend upward, locking into the first limiting slot 71. That is, at the same time that the first connecting structure 7 is disconnected, the second connecting structure 8 is connected.

[0056] When the first connecting structure 7 needs to be connected, the driving structure 312 drives the clamping member 311 and causes the two locking blocks 72 to move away from each other. The locking blocks 72 gradually enter the first limiting slot 71. At the same time, the second inclined surface 721 gradually connects and compresses the telescopic locking block 82 downward. When the locking block 72 is locked in place with the first limiting slot 71, the telescopic locking block 82 disengages downward from the first limiting slot 71. That is, the first connecting structure 7 forms a connection at the same time as the second connecting structure 8 disconnects.

[0057] Optionally, see Figure 8 and 9 The second connection structure includes two opposing first limiting slots 71, a telescopic block 82 mounted on the frame 1 and driven by elastic force to move along the second direction, and a first inclined surface 231 mounted on the docking platform 2 to compress the telescopic block 82 when the docking platform 2 moves along the first direction; the first limiting slots 71 are through slots along the second direction.

[0058] Thus, the first limiting slot 71 can serve as part of both the first connecting structure 7 and the second connecting structure 8. Specifically, the first limiting slot 71 can be provided on the connecting rod 23. The first limiting slot 71 is a through hole in the second direction. A first inclined surface 231 is provided on the side of the first limiting slot 71 in the first direction. The first inclined surface 231 gradually slopes horizontally along the first direction.

[0059] When the first connecting structure 7 needs to be connected, the driving structure 312 drives the clamping member 311 and causes the two locking blocks 72 to move away from each other, and the locking blocks 72 are locked into the first limiting slot 71.

[0060] When the second connecting structure 8 is required for connection, the first moving device 5 drives the docking platform 2 to the right along the first direction ( Figure 8 When the door panel 22 of the middle docking platform 2 (located on the left) moves, the first inclined surface 231 will contact and gradually move outward in the second direction ( Figure 9 Press the telescopic locking block 82 (up and down) and when the first limiting slot 71 moves to the position of the telescopic locking block 82, the telescopic locking block 82 will abut against the end of the locking block 72. When the two locking blocks 72 move closer together, the locking block 72 will disengage from the first limiting slot 71. At the same time, the telescopic locking block 82 will gradually be inserted into the first limiting slot 71 from the outside to the inside under the action of elastic force. That is, the second connecting structure 8 is connected at the same time as the first connecting structure 7 is disconnected.

[0061] When the first connecting structure 7 needs to be connected, the driving structure 312 drives the clamping member 311 and causes the two locking blocks 72 to move away from each other. The locking blocks 72 gradually enter the first limiting slot 71. At the same time, the end of the locking block 72 contacts the telescopic locking block 82 and presses the telescopic locking block 82 outward. When the locking block 72 is locked in place with the first limiting slot 71, the telescopic locking block 82 disengages outward from the first limiting slot 71. That is, the first connecting structure 7 is connected at the same time as the second connecting structure 8 is disconnected.

[0062] Optionally, see Figure 3 The first moving device 5 is also provided with a battery tray 53 for supporting the battery. The battery tray 53 can be disposed on the first slider 52 and located beside the clamping device 3 along the first direction. The battery tray 53 serves to support the battery when the clamping device 3 clamps and moves the battery.

[0063] Optionally, the second limiting structure includes a guide positioning part disposed on the frame 1 for contacting the electric motor to adjust the orientation of the electric motor during the process of the docking platform 2 moving to the first position, and a thrust part disposed on the docking platform 2 for preventing the electric motor from moving away from the charging device in the first direction. The guide positioning part is adapted to the first positioning part of the electric motor.

[0064] Some electric mobile devices, such as drones, may not have high enough landing positioning accuracy to land precisely at a preset position. When the docking platform 2 moves the electric mobile device to the first position, the battery may not be directly aligned with the clamping device 3, and the clamping structure 31 cannot clamp it. By setting the second limiting structure as a guide positioning part and a thrust part, if the orientation of the electric mobile device deviates during the movement from the second position to the first position by the docking platform 2, the first positioning part on the electric mobile device will contact or collide with the guide positioning part, thus adjusting it to the correct orientation during the movement. The first positioning part and the guide positioning part are compatible, allowing the battery to be aligned with the clamping structure 31 for easy battery installation and removal. This increases the adaptability of the battery replacement device, enabling it to replace batteries from electric mobile devices with poor docking positioning accuracy.

[0065] Specifically, see Figure 1The guide positioning part can be a constricted structure 11, the opening of which gradually decreases as it approaches the charging device 4 along the first direction. A first positioning part can be provided on the electric motor, matching the end (small end) of the constricted structure 11. Thus, when the first moving device 5 drives the docking platform 2 and the electric motor to move along the first direction, if there is a positional deviation in the electric motor, the first positioning part will contact or collide with the constricted structure 11, thereby correcting the orientation of the electric motor. Specifically, the constricted structure 11 of the frame 1 can be a figure-eight structure, and the first positioning part on the electric motor can be a trapezoidal block that matches the figure-eight structure.

[0066] Optionally, the frame 1 can be configured as a box, and the charging device 4, clamping device 3, and docking platform 2 can be partially or entirely housed within the box. This arrangement provides dust protection and other protective functions. The box has an opening for the docking platform 2 to enter and exit. A door panel 22 is installed on the docking platform 2. When the docking platform 2 is moved out, the door panel 22 moves out with it; when the docking platform 2 is moved back, the door panel 22 moves back with it, sealing the opening.

[0067] Optionally, the second moving device 6 is a translational device, or the second moving device 6 is a rotating device.

[0068] Optionally, see Figure 1 , Figure 9 and Figure 10 , Figure 9 This is an inverted schematic diagram of the charging device 4. The second moving device 6 is a translational device. The charging rack 41 is mounted on the slider of the second moving device 6. The charging position 411 includes a guide groove 4111 extending along a first direction and containing a supporting surface. The guide groove 4111 is provided with a limiting groove 4112 that is concave outward. The limiting groove 4112 has a first end face 41121 and an end face opposite to the first end face 41121 along the first direction. The end of the guide groove 4111 away from the docking platform 2 is connected to a fixing plate 4113. A first charging electrode 4114 is provided on the fixing plate 4113. The guide groove 4111 forms a supporting structure, and the limiting groove 4112 forms a first limiting structure.

[0069] See Figure 12 and Figure 13The first locking structure of the battery can be two elastic fins 100 disposed on two sides of the battery. Each elastic fin 100 has a clamping part 101 and a first protruding edge 102. The clamping part 101 may have a protrusion. The two sides of the battery have second protruding edges 110. When the clamping part 101 is clamped, the two elastic fins 100 approach each other, and the first protruding edge 102 aligns with the second protruding edge 110, acting as a slider. A second charging electrode is disposed on the side of the battery opposite to the fixing plate 4113. When the clamping part 101 is clamped, the two elastic fins 100 approach each other, and the first protruding edge 102 aligns with the second protruding edge 110, acting as a slider. It can slide along the guide groove 4111 into and out of the charging position 411. When it is in position, the second charging electrode on the battery is connected and conductively connected to the first charging electrode 4114. After the clamping structure 31 releases the clamping part 101, the two elastic fins 100 move away from each other, and the two first protrusions 102 are engaged in the limiting groove 4112. The two end faces of the limiting groove 4112 along the first direction (i.e. Figure 9 The first end face 41121 and the end face opposite to the first end face 41121 along the first direction respectively contact the two end faces of the first protrusion 102 along the first direction to restrict the movement of the battery along the first direction. When the clamping structure 31 clamps the clamping part 101 of the battery, the two elastic fins 100 approach each other, and the two first protrusions 102 disengage from the limiting groove 4112.

[0070] See Figure 11 A detection element 4115 can be provided at the limiting groove 4112. The detection element 4115 is used to detect whether the battery is installed in place. Specifically, the detection element 4115 can be a contact sensor. When the first protrusion 102 of the battery presses on the contact sensor, it indicates that the battery is installed in place, and the contact sensor transmits a signal to the controller.

[0071] In order to make the clamping more secure, when the clamping part 101 of the battery is provided with a protrusion, the two jaws of the clamping structure 31 can be provided with grooves 3111 that match the protrusion.

[0072] Optionally, see Figure 1 and Figure 4 The docking platform 2 includes a support part, which can be a support plate 21. The support plate 21 is provided with a through hole 211 for the battery to pass through downward. The trapezoidal edge 212 of the through hole 211 can form a thrust part. The electric motor can be provided with a trapezoidal second positioning block corresponding to the trapezoidal edge 212. When the electric motor is docked on the docking platform 2, the second positioning block presses against the trapezoidal edge 212, which can prevent the electric motor from moving away from the charging device 4 in the first direction, so as to facilitate the loading of the battery.

[0073] For some electric mobile devices, such as drones, the battery is installed at the bottom of the drone. During normal landing, the bottom of the battery contacts the ground, supporting the drone. Removing or installing the battery can affect this support. By adding a through-hole 211 to the support, the battery can pass downwards through the through-hole 211 and remain suspended in the air after landing, allowing the rest of the drone (excluding the battery) to contact the support. This facilitates battery installation and removal.
