Detailed implementation mode

[0028] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation modes described in the following exemplary embodiments do not represent all the implementation modes consistent with the present invention. On the contrary, they are only examples of devices or methods consistent with some aspects of the present invention.

[0029] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation modes obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope protected by the present invention.

[0030] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not limit the content of the utility model described in the claims in any way. In addition, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims.

[0031] See Figures 1-5 , the present utility model provides a battery replacement device, including a frame body 1. Here, the frame body 1 can refer to the ground, the fixed surface of a building (such as a wall surface, the ground, etc.). It can also refer to a support structure for placing or fixing at a certain position, and the support structure can be a box body, a bracket, etc. Along the first direction, a docking platform 2, a charging device 4, and a clamping device 3 are sequentially arranged on the frame body 1, and the first direction is the longitudinal direction of the frame body 1. In Figure 1 , the first direction refers to the left - right direction of the drawing. In Figure 2 , the first direction refers to the up - down direction of the drawing. Figure 2Inside, a docking platform 2, a charging device 4, and a clamping device 3 are sequentially arranged from top to bottom. A second limiting structure for limiting the electric-powered mover is provided on the frame 1 and / or the docking platform 2. The second limiting structure is used to prevent the electric-powered mover from moving in the first direction when the battery is being disassembled and assembled. The electric-powered mover can be a drone, an electric vehicle, a battery car, etc. When the electric-powered mover docks on the docking platform 2, the docking platform 2 supports the electric-powered mover and leaves a space for the battery to move, that is, there is a clamping space on both sides of the battery of the electric-powered mover, and the battery does not play a role in supporting the electric-powered mover. Other parts of the electric-powered mover except the battery are in contact with the docking platform 2 to support the electric-powered mover, so that when the battery is being disassembled and assembled, it will not affect the docking of the electric-powered mover. For example, the battery can be suspended, or although the battery is in contact with the docking platform 2, it does not play a supporting role. For some drones, a support frame is provided below them, and the battery of the drone is also arranged at the bottom of the drone. The support frame supports the drone and the battery is suspended. At this time, the structure of the docking platform 2 can be unrestricted. The clamping device 3 includes a first moving device 31. A clamping structure 32 and an unlocking structure are provided on the first moving device 31. The clamping structure 32 is used to connect with the battery, specifically, it can clamp both sides of the battery; the unlocking structure is used to unlock the first locking structure of the battery and lock the first locking structure of the battery. The first locking structure provided on the battery can lock the battery in the battery compartment of the electric-powered mover. After the unlocking structure unlocks the first locking structure, the battery can be translated in the first direction and taken out of the battery compartment, or can be translated in the first direction and installed into the battery compartment. The first moving device 31 is used to drive the clamping structure 32 and the unlocking structure to move in the first direction. The charging device 4 includes a charging rack 42 and a second moving device 41. The charging rack 42 includes at least two charging positions 421. The second moving device 41 is used to drive the charging rack 42 to move so that the second moving device 41 can move the charging rack 42 to a position where the required charging position 421 is directly opposite to the clamping device 3 in the first direction. Specifically, the second moving device 41 can drive the charging rack 42 to move in a plane direction perpendicular to the first direction, that is, the charging rack 42 can move in a vertical plane, specifically, it can be translational or rotational. It can also drive the charging rack 42 to move on a horizontal plane, specifically, it can be translational or rotational. The translational motion here includes both linear motion and curvilinear motion. It only needs to be ensured that the second moving device 41 can align the required charging position 421 with the clamping device 3 (and the battery) in the first direction, and at the same time stagger the unnecessary charging positions 421 from the clamping device 3 (and the battery).

[0032] Each charging position 421 can be provided with a first charging electrode 4214, 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 3 clamps the battery and moves the battery to a preset position of the charging position 421 along the first direction, that is, when the battery is correctly installed in the charging position 421, the second charging electrode of the battery is connected and conducted with the first charging electrode 4214. The specific setting of the first charging electrode 4214 may not be limited, as long as it meets the condition that the battery only needs to move into the charging position along the first direction, and after reaching the preset position, the second charging electrode on the battery is connected and conducted with the first charging electrode 4214 to enable charging. For example, the first charging electrode 4214 can be arranged on the surface of the charging position 421 opposite to the battery in the first direction, or on the surface of the charging position 421 opposite to the upper or lower surface of the battery. Figure 3 The situation shown in Figure 3 is that the first charging electrode 4214 can be arranged on the surface of the charging position 421 opposite to the battery in the first direction.

[0033] See Figure 4 , the first moving device 31 can be a linear module, including a first slide rail 311 and a first slider 312. The first slider 312 and the clamping structure 32 can be connected by a connecting rod 33.

[0034] Battery disassembly and assembly process: After the electric mover docks at the docking platform 2, the battery is also aligned with the clamping device 3 along the first direction. See Figure 1 , the first direction is Figure 1 the left - right direction in Figure 1 . When disassembling the battery, the second moving device 41 drives the charging rack 42 to move back and forth (the front refers to the direction perpendicular to the paper surface and outward), so that the empty charging position 421 is aligned with the battery. The first moving device 31 drives the clamping structure 32 to pass through from the left side of the empty charging position 421 and move to the right to the position of the battery on the electric mover at the docking platform 2. Clamp both sides of the battery through the clamping structure 32, unlock the first locking structure of the battery through the unlocking structure, and then return to the left to extract the battery. Then continue to move to the left into the empty charging position 421. After moving in place, the second charging electrode of the battery is connected and conducted with the first charging electrode 4214 for charging. The unlocking structure locks the first locking structure at the first limiting structure on the charging position 421. The clamping structure 32 and the unlocking structure continue to move to the left and move back to the left side of the charging device 4.

[0035] Subsequently, the battery is loaded. The second moving device 41 drives the charging rack 42 to move back and forth, aligning the charging position 421 with a fully charged battery with the clamping device 3. The first moving device 31 drives the clamping structure 32 to enter the charging position 421 from the left side of the charging position 421, clamping both side portions of the battery. The unlocking mechanism unlocks the first locking structure and the first limiting structure so that the battery can be removed from the charging position 421 along the first direction. Subsequently, the clamping structure 32 clamps the battery and moves it to the right until it reaches the position of the electric power mover. The battery is then further pushed into the battery compartment of the electric power mover to the right. After being installed in place, the unlocking structure locks the first locking structure to the battery compartment, and the clamping structure 32 releases the battery, completing the installation of the battery. Subsequently, the clamping structure 32 can move back to the initial position to the left.

[0036] In this battery replacement device, the docking platform 2, the charging device 4, and the clamping device 3 are arranged in sequence along the first direction. The charging device 4 is provided with a space for the clamping device 3 to pass through. The clamping device 3 can reciprocate along the first direction through the charging device 4, thereby removing the battery of the electric power mover from the docking platform 2, then moving the battery to the charging device 4 for charging, taking the charged battery from the charging device 4, moving it to the docking platform 2, and installing it on the electric power mover. The charging device 4 is provided with at least two charging positions 421, and the charging positions 421 can move in a plane direction perpendicular to the first direction. In this way, when disassembling the battery, the empty charging position 421 can be aligned with the clamping device 3, and when installing, the charging position 421 with the battery placed on it can be aligned with the clamping device 3 to facilitate the disassembly and installation of the battery. During this process, the clamping device 3 only needs to move back and forth in the first direction to complete the disassembly and assembly of the battery on the electric power mover, the transportation of the battery between the charging device 4 and the docking platform 2, and the disassembly and assembly of the battery on the charging device 4. The disassembly and assembly operations are relatively simple, the disassembly and assembly time is short, and the battery of the electric power mover can be replaced quickly.

[0037] Optionally, a third moving device is further provided on the frame 1. The docking platform 2 is connected to the third moving device, and the third moving device moves the docking platform 2 to a first position for disassembling and assembling the battery of the electric power mover and a second position for docking and departing of the electric power mover.

[0038] To facilitate the docking and departure of the electric power mover, a third moving device is added to drive the docking platform 2 to move. When the docking platform 2 moves to the second position, the electric power mover can dock. Subsequently, the docking platform 2 drives the electric power mover to move to the first position for battery replacement. After replacement, the docking platform 2 drives the electric power mover to move to the second position for the electric power mover to depart.

[0039] Specifically, the movement form of the third moving device may not be limited. It can perform translational movement, rotational movement, or both rotational and translational movement. It can perform translational movement on a horizontal plane or in the vertical direction.

[0040] Optionally, the second limiting structure includes a guiding and positioning portion provided on the frame 1 for contacting the electric power mover during the process of the docking platform 2 moving to the first position to adjust the orientation of the electric power mover, and a thrust portion provided on the docking platform 2 for preventing the electric power mover from moving away from the charging device along the first direction. The guiding and positioning portion is adapted to the first positioning portion of the electric power mover.

[0041] For some electric power movers, such as drones, the landing positioning accuracy may not be high enough, and they cannot directly and accurately land at a preset position. When the docking platform 2 drives the electric power mover to move to the first position, the battery is not directly aligned with the clamping device 3, and the clamping structure 32 cannot clamp it. By setting the second limiting structure in the form of a guiding and positioning portion and a thrust portion, during the process of the docking platform 2 driving the electric power mover from the second position to the first position, if there is a deviation in the orientation of the electric power mover, a first positioning portion can be provided on the electric power mover. The first positioning portion will contact or collide with the guiding and positioning portion and be adjusted to the correct direction during the movement, so that when reaching the first position, the first positioning portion is adapted to the guiding and positioning portion, enabling the battery to be aligned with the clamping structure 32 for battery disassembly and assembly. In this way, the adaptability of this battery replacement device can be increased, and it can adapt to the replacement of batteries of electric power movers with poor docking position accuracy.

[0042] Optionally, the third moving device moves along the first direction, and the guiding and positioning portion is a constricted structure with a gradually decreasing opening when approaching the charging device 4 along the first direction.

[0043] Preferably, the third moving device performs translational movement along the first direction. At this time, the guiding and positioning portion can be a constricted structure 51. The opening of the constricted structure 51 gradually decreases when approaching the charging device 4 along the first direction. A first positioning block can be provided on the electric power mover, and the first positioning block matches the end (small end) of the constricted structure 51. In this way, when the third moving device drives the docking platform 2 and the electric power mover to move along the first direction, if there is a position deviation of the electric power mover, the first positioning portion thereon will contact or collide with the constricted structure 51 until the orientation of the electric power mover is straightened. Specifically, a fixing rod 52 can be provided on the frame 1, and the constricted structure 51 can be an "eight"-shaped structure formed by two guiding rods provided on the fixing rod 52. The first positioning portion on the electric power mover can specifically be a trapezoidal first positioning block that matches the "eight"-shaped structure.

[0044] Optionally, the frame 1 can be set as a box body, and the charging device 4, the clamping device 3, and the docking platform 2 can be partially or wholly arranged inside the box body, and the box body is provided with an openable and closable opening for the docking platform to enter and exit.

[0045] In this way, the charging device 4, the clamping device 3, and the docking platform 2 being partially or wholly arranged inside the box body can play a role in protection such as dust prevention. The openable and closable opening on the box body can specifically be a baffle 11 provided with an opening and connected to the box body; alternatively, an opening can be provided on the box body, and a door panel can be provided on the docking platform 2, and when the docking platform 2 is moved out, the door panel is moved out with the docking platform 2, and when the docking platform 2 is moved back, the door panel is moved back with the docking platform 2 to seal the opening.

[0046] Optionally, the unlocking structure and the clamping structure 32 are the same structure. The first locking structure includes a clamping part arranged on the side of the battery. When the clamping structure 32 is closed to clamp the clamping part, the first locking structure is unlocked, and when the clamping structure is opened, the first locking structure is locked.

[0047] Setting the unlocking structure and the clamping structure 32 as the same structure has two advantages. One is that the structure is simple, and the other is that the clamping process and the unlocking process are realized by one action, and the loosening process and the locking process are realized by one action, which can further reduce the time for battery replacement. The battery compartment of the electric mover can be provided with guiding and limiting structures similar to the charging position 421. For the specific unlocking and locking processes, reference can be made to the following text.

[0048] Optionally, the second moving device 41 is a translation device, or the second moving device 41 is a rotating device.

[0049] Optionally, referring to Figure 1 and Figure 3 , Figure 3 is an inverted schematic diagram of the charging device 4. The second moving device 41 is a translation device. The second moving device 41 includes a second slide rail 411 extending along a horizontal direction perpendicular to the first direction and a second slider 412 arranged on the second slide rail 411. The charging rack 42 is connected to the second slider 412 and is located below the second slide rail 411. The charging position 421 includes a guiding groove 4211 extending along the first direction and having a supporting surface. The guiding groove 4211 is provided with a limiting groove 4212 recessed outward. The limiting groove 4212 has a first end surface 42121 and an end surface opposite to the first end surface 42121 along the first direction. One end of the guiding groove 4211 far from the docking platform 2 is connected to a fixing plate 4213, and a first charging electrode 4214 is arranged on the fixing plate 4213; the guiding groove 4211 forms a supporting structure, and the limiting groove 4212 forms a first limiting structure.

[0050] Referring to Figure 6 and Figure 7, the first locking structure of the battery can be two elastic fins 80 provided on two side portions of the battery. A clamping portion 801 and a first convex edge 802 are provided on the elastic fin 80. A protrusion can be provided on the clamping portion 801. Second convex edges 81 are provided on two side portions of the battery. When the clamping portion 801 is clamped, the two elastic fins 80 approach each other, and the first convex edge 802 is aligned with the second convex edge 81, acting as a slider. A second charging electrode is provided on a side of the battery opposite to the fixed plate 4213. After the clamping portion 801 is clamped, the two elastic fins 80 approach each other, and the first convex edge 802 is aligned with the second convex edge 81, acting as a slider, and can slide into and out of the charging position 421 along the guide groove 4211. When in place, the second charging electrode on the battery is exactly connected and conducted with the first charging electrode 4214. After the clamping structure 32 releases the clamping portion 801, the two elastic fins 80 move away from each other, and the two first convex edges 802 are stuck in the limit groove 4212. Two end faces of the limit groove 4212 along the first direction (that is, Figure 5 the first end face 42121 in

[0051] and the end face opposite to the first end face 42121 along the first direction) are respectively in contact with two end faces of the first convex edge 802 along the first direction to limit the movement of the battery along the first direction. When the clamping structure 32 clamps the clamping portion 801 of the battery, the two elastic fins 80 approach each other, and the two first convex edges 802 disengage from the limit groove 4212. Figure 5 , at the limit groove 4212, a detection member 4215 can be provided. The detection member 4215 is used to detect whether the battery is installed in place. Specifically, the detection member 4215 can be a contact sensor. When the first convex edge 802 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.

[0052] Among them, in order to facilitate firmer clamping, when a protrusion is provided on the clamping portion 801 of the battery, grooves 321 matching the protrusion can be provided on two clamping jaws of the clamping structure 32.

[0053] Optionally, referring to Figure 1 , the docking platform 2 includes a support portion. The support portion can be a support plate 21. A through hole 211 for the battery to pass through downward is provided on the support plate 21. The trapezoidal edge 212 of the through hole 211 can form a thrust portion. A corresponding trapezoidal second positioning block can be provided on the electrokinetic mover. When the electrokinetic mover docks on the docking platform 2, the second positioning block abuts against the trapezoidal edge 212, which can prevent the electrokinetic mover from moving away from the charging device 4 along the first direction, so as to facilitate the loading of the battery.

[0054] For some electric movers, such as drones, the battery is installed at the bottom of the drone. When landing normally, the bottom of the battery will contact the ground and play a role in supporting the drone. When disassembling and assembling the battery, it will affect the support of the drone. By adding a through hole 211 to the support part, after the drone lands, the battery can pass downward through the through hole 211 and be suspended, and the part of the drone other than the battery will contact the support part. Thus, it is convenient for the disassembly and assembly of the battery.

[0055] Optionally, referring to Figure 1 and Figure 2 , a battery auxiliary guiding device 6 for auxiliary support and auxiliary guiding is further provided on the frame body 1 when the clamping device 3 clamps the battery and moves in the first direction. The battery auxiliary guiding device 6 can be adapted to the bottom of the battery to form a guide rail for the battery to slide, so as to play a role in auxiliary supporting the battery and auxiliary guiding when the clamping device 3 clamps the battery and moves in the first direction, which can reduce the force on the clamping device 3 and thus make the movement of the battery smoother.

[0056] It should be noted that the structures of the first moving device, the second moving device, and the third moving device in this application are not specifically limited. It can be a linear module. It can also use a ball screw structure, a cylinder structure, a hydraulic cylinder structure, etc. as the power source, and a slide rail and slider structure as the guiding structure, combined to obtain the moving device. Figure 2 The third moving device shown in is a linear module, including a third slide rail 7. The third slide rail 7 can be arranged at the bottommost, and a third slider can be arranged on the third slide rail 7. The docking platform 2 can be a front cantilever structure. The docking platform 2 includes a support plate 21, and a support body is arranged below the support plate 21. The support body is connected to the third slider.
