Fig. 1 is a schematic structural diagram of a battery swapping apparatus 10. As shown in fig. 1, the battery replacing apparatus 10 includes a base and a connecting assembly 13 connected to the base, the connecting assembly 13 is used for docking the battery box 20, and the connecting assembly 13 is connected to the base, so that the base can move the battery box 20 through the connecting assembly 13 to replace the battery box 20 for a vehicle.

Fig. 2 is a schematic structural view of the battery case 20. As shown in fig. 2, a bracket 21 is provided at the top of the battery box 20 for connecting the battery charger 10. The bracket 21 has a substantially frame-like structure including side members extending in the lengthwise direction of the battery case 20 and a cross bar 211 connected to the side members. In this embodiment, the number of the cross bars 211 is two, and a preset distance exists between the cross bars 211, so that the battery replacement device 10 can be simultaneously connected to the two cross bars 211 to balance the stress condition of the cross bars 211. In addition, one of the cross bars 211 is further provided with a jack 212 to fix the battery box 20, so as to prevent the battery box 20 from being separated from the battery replacement device 10 during the moving process.

The substrate may be in various forms according to the application of the battery replacing device 10. In some embodiments, the base is located above the battery box 20 and is movable in XYZ directions, such that the connection assembly 13 can move the battery box 20 following the movement of the base.

Illustratively, as shown in fig. 1, in the present embodiment, the base body includes a frame 11 and a robot arm 12. The rack 11 has a substantially "door" shaped structure and can be moved in a vertical direction or a horizontal direction by an external force to move the battery box 20. The robot arm 12 is attached to an upper portion of the frame 11 and can be extended and retracted in a horizontal direction as shown in fig. 1.

Fig. 3 is a schematic view of the structure of the robot arm 12 and the connecting assembly 13. As shown in fig. 3, the robot arm 12 is used to move the battery box 20, and in this embodiment, the robot arm 12 is connected to the rack 11 so as to be movable along with the rack 11. In some embodiments, the robotic arm 12 includes a telescoping mechanism 121 and a base plate. The telescoping mechanism 121 is connected to the gantry 11 such that the robotic arm 12 can be extended from or retracted into the gantry 11. The telescopic mechanism 121 of the mechanical arm 12 may be implemented in various manners, for example, a telescopic cylinder, a ball screw, a linear motor, etc. may be used to implement a telescopic structure, but those skilled in the art may also implement a telescopic function of the mechanical arm 12 in other manners, which is not limited in this application.

The bottom plate 122 has a substantially flat plate-shaped structure, and the bottom plate 122 is movably connected to the telescoping mechanism 121, for example, movably connected to an end of the telescoping mechanism 121 by a chute-slider structure, a ball screw structure, or the like, and can be moved along the telescoping mechanism 121 within a moving stroke range by a driving mechanism of the robot arm 12 or an independent driving mechanism (for example, a linear motor, a gear-rack mechanism, a ball screw mechanism, or the like), so that the stroke of the coupling assembly can be increased.

With continued reference to fig. 3, the connecting assembly 13 is adapted to dock with the battery box 20. The connecting assembly 13 includes a driving mechanism 131, a first bearing portion 132, and a second bearing portion 133.

The widths of the first bearing part 132 and the second bearing part 133 are smaller than the width of the bracket 21 of the battery case 20. One end of the first bearing portion 132 and the second bearing portion 133 is fixedly connected to the bottom surface of the bottom plate 122, and the other end extends towards the end direction of the robot arm 12 (i.e. the horizontal direction shown in fig. 1), so that the first bearing portion 132 and the second bearing portion 133 form an "L" shaped structure. When the robot arm 12 moves toward the battery box 20 until the first bearing part 132 and the second bearing part 133 are located below the cross bar 211 of the rack 21 of the battery box 20, the first bearing part 132 and the second bearing part 133 move upward along with the robot arm 12, and respectively lift up the cross bar 211 to move the battery box 20.

Further, in order to prevent the battery box 20 from being detached from the connection assembly 13 during movement, in some preferred embodiments, the connection assembly 13 further includes a latch 1321 and a receptacle 212. The latch 1321 extends in a vertical direction and corresponds to the insertion hole 212 of the cross bar 211. When the first bearing part 132 is located below the cross bar 211, the first bearing part 132 moves upward along with the mechanical arm 12, so that the latch 1321 is inserted into the insertion hole 212, thereby preventing the battery box 20 from being separated from the first bearing part 132 during the moving process. In other embodiments, the latch 1321 may be disposed on the cross bar 211 of the battery box 20, and correspondingly, the receptacle 212 is disposed on the first bearing part 132 and corresponds to the latch 1321. When the first bearing part 132 is located below the cross bar 211, the first bearing part 132 moves upward along with the mechanical arm 12, so that the plug 1321 is sleeved with the insertion hole 212, and the function of preventing the battery box 20 from being separated from the first bearing part 132 in the moving process can also be achieved.

When the battery box 20 needs to be moved, when the mechanical arm 12 extends towards the battery box 20 until the connecting assembly 13 is located above the battery box 20, the height of the mechanical arm 12 is adjusted so that the heights of the first bearing part 132 and the second bearing part 133 of the connecting assembly 13 at the end part of the mechanical arm 12 are lower than the height of the cross bar 211 of the support 21 of the battery box 20, and then the mechanical arm 12 continues to extend to be close to the support 21 of the battery box 20 until the first bearing part 132 and the second bearing part 133 are respectively located below the cross bar 211 of the battery box 20.

Next, the robot arm 12 moves upward, so that the first bearing part 132 and the second bearing part 133 respectively bear the crossbar 211 of the battery box 20 from below the crossbar 211, and the function of hooking the battery box 20 is realized. Since the width of the connecting portion 131 is smaller than that of the bracket 21, the robot arm 12 can be connected to the battery box 20 without adjusting the postures of the first bearing portion 132 and the second bearing portion 133 again. During the upward movement of the first carrying part 132, the latch 1321 is inserted into the insertion hole 212 of the cross bar 211, so as to prevent the battery box 20 from being separated from the first carrying part 132 during the movement.

Fig. 4 is a schematic structural view of the second bearing part 133. In order to facilitate the adjustment of the angle of the battery box 20, to facilitate the handling of the battery box 20, or to release the battery box 20 after moving the battery box 20 to a predetermined position, the angle of the battery box 20 needs to be adjusted. As shown in fig. 4, the connection assembly further includes a driving mechanism 131 for driving the second bearing portion 133 to move in a direction perpendicular to the extending and contracting direction of the robot arm 12, so that the angle of the battery box 20 can be adjusted. Specifically, the driving mechanism 131 is connected to the robot arm, and is configured to drive the battery box 20 to rotate around the latch 1321 to adjust the angle of the battery box 20 when the first supporting portion 132 and the second supporting portion 133 support the crossbar 211 of the battery box 20.

In order to facilitate the rotation of the battery box 20, in the embodiment shown in fig. 4, the second bearing portion 133 is movably connected to the bottom plate 122 of the mechanical arm 12, for example, movably connected to the bottom plate 122 through a slider-slide structure, so that the second bearing portion 133 can move in a direction perpendicular to the extending and contracting direction of the mechanical arm 12 (i.e., the width direction of the battery box 20). The driving mechanism 131 is connected to the second bearing part 133 to drive the second bearing part 133 to move along the width direction of the battery box 20, and the second bearing part 133 supports the cross bar 211 of the bracket 21 of the battery box 20, so that the angle of the battery box 20 can be adjusted by moving the second bearing part 133. As will be appreciated by those skilled in the art, the drive mechanism 131 may be implemented in a variety of forms or configurations, and by way of example, in the embodiment illustrated in fig. 4, the drive mechanism 131 includes a first drive motor 1311, a drive wheel 1312, and a drive chain 1313. The driving wheel 1312 is rotatably connected to the bottom plate 122, the first driving motor 1311 is connected to the driving wheel 1312, the driving chain 1313 bypasses the driving wheel 1312 and is connected to the second supporting portion 133, the first driving motor 1311 can drive the driving wheel 1312 to rotate, the driving wheel 1312 can drive the driving chain 1313 to move when rotating, and the second supporting portion 133 is connected to the driving chain 1313, so that the driving chain 1313 can drive the second supporting portion 133 to move when moving, thereby driving the battery box 20 to rotate around the bolt 1321 to adjust the angle of the battery box 20.

However, the drive mechanism 131 may be of other forms and configurations. Fig. 5 is a schematic structural view of another embodiment of the driving mechanism 131, and as shown in fig. 5, the second bearing part 133 is fixedly connected to the bottom plate 122 and extends toward the end of the robot arm 12. The driving mechanism 131 may include a first driving motor 1311 and a driving rod 1314, the driving rod 1314 extending in the width direction of the battery case 20 and being connected to the first driving motor 1311. The driving rod 1314 may be moved in the width direction of the battery case 20 by the first driving motor 1311, so as to push the battery case 20 to rotate during the movement. However, other structures and manners of driving mechanism 131 may be adopted by those skilled in the art, and the present application is not limited thereto.

When the battery replacing device is used, in the process that the mechanical arm 12 drives the connecting assembly 13 to move upwards, the plug pin 1321 is inserted into the insertion hole 212 of the cross rod 211 of the support 21 of the battery box 20, so that the battery box 20 can be prevented from being separated from the connecting assembly 13 in the moving process, and the safety of the battery replacing device 10 is further improved.

Then, the robot arm 12 moves the battery box 20, and moves the battery box 20 to a predetermined position. In the present embodiment, in order to move the battery box 20 to the vehicle or the charging stand, the robot arm 12 starts the retracting action after the coupling assembly 13 hooks the battery box 20, so that the battery box 20 moves into the rack 11 to move the battery box 20. The inventor finds in practice that the battery box 20 may shake during the movement of the battery replacement device 10 due to the fact that the connection assembly 13 hooks the battery box 20.

Fig. 6 is a schematic structural diagram of the battery replacing device 10 when moving the battery box 20 to a specified position. As shown in fig. 6, in some preferred embodiments, the battery replacing apparatus 10 further includes a clamping mechanism 14, so that when the battery box 20 is moved to a preset position (e.g., inside the rack 11 in this embodiment), the clamping mechanism 14 clamps the battery box 20 to reduce the shaking degree of the battery box 20 during the process of carrying the battery box 20 by the battery replacing apparatus 10.

Fig. 7 is a schematic structural view of the chucking mechanism 14. As shown in fig. 6 and 7, the chucking mechanism 14 illustratively includes a second driving motor 141, a turntable 142, a connecting rod 143, and a chucking arm 144. The second driving motor 141 is connected to the bottom of the frame 11, and the turntable 142 is connected to an output shaft of the second driving motor 141 and can be driven by the second driving motor 141 to rotate. The number of the connecting rods 143 is two, and the end parts are hinged to the rotating disc 142. The number of the holding arms 144 is two, and they are respectively located on both sides of the battery case 20. The clamping arm 144 is hinged at its middle portion to the frame 11 and is hinged at one end to the connecting rod 143 and at the other end rotatably connected to the roller 145. When the battery box 20 moves into the rack 11, the second driving motor 141 drives the rotating disc 142 to rotate, and the clamping arm 144 is pulled by the connecting rod 143 to swing so as to clamp the two sides of the battery box 20, so that the shaking condition of the battery box 20 can be reduced, and the stability of the battery box 20 in the moving process of the battery replacing device 10 is improved. However, it is understood by those skilled in the art that the structure of the clamping mechanism 14 may be various, and for example, the clamping mechanism may include telescopic rods disposed at both sides of the rack 11, and when the battery box 20 is located in the rack 11, the telescopic rods extend to abut against both sides of the battery box 20, so as to achieve the function of fixing the battery box 20.

The operation of the battery replacement device 10 is described in detail below.

When the battery box 20 needs to be moved, the battery replacing device 10 is moved to a position corresponding to the battery box 20, and then the mechanical arm 12 is extended towards the battery box 20 until the connecting assembly 13 is positioned above the bracket 21 of the battery box 20.

Then, the robot arm 12 moves in the vertical direction and/or in the extending direction, so that the connecting assembly 13 moves along with the bottom plate 122 of the robot arm 12 until the connecting portion 131 extends below the cross bar 211 to hook the cross bar 211 of the battery box 20.

Next, the robot arm 12 moves upward so that the connection portion 131 contacts the crossbar 211 of the battery box 20 and the latch 1321 is inserted into the insertion hole 212 of the crossbar 211, and as the robot arm 12 continues to move upward, the robot arm 12 hooks the battery box 20 through the connection assembly 13 and moves upward. Because the widths of the first bearing part 132 and the second bearing part 133 are smaller than the width of the bracket 21 of the battery box 20, the first bearing part 132 and the second bearing part 133 have larger moving spaces to move below the cross rod 211, so that the posture of the first bearing part 132 or the second bearing part 133 can be prevented from being adjusted during butt joint, and the battery replacement efficiency is effectively improved.

During the upward movement of the robot arm 12, the latch 1321 moves upward to be inserted into the insertion hole 212 of the cross bar 211 along with the first bearing part 132. Then, the driving mechanism 131 pulls the second bearing part 133 to move, so that the battery box 20 can be driven to rotate around the latch 1321 to adjust the angle of the battery box 20.

The robotic arm 12 then begins to retract until the battery box 20 moves to a preset position within the housing 11. Preferably, the preset position may be an inner space of the housing 11. Then, the second driving motor 141 of the clamping mechanism 14 drives the clamping arm 144 to rotate to clamp the two sides of the battery box 20, so that the shaking degree of the battery box 20 during the movement of the battery replacement device 10 can be reduced.

According to the battery replacing device 10 and the battery replacing method, the connecting assembly 13 is arranged on the mechanical arm 12, the connecting assembly 13 is provided with the first bearing part 132 and the second bearing part 133, when the mechanical arm 12 moves towards the battery box 20 until the first bearing part 132 and the second bearing part 133 are located below the cross bar 211 of the support 21 of the battery box 20, the mechanical arm 12 drives the first bearing part 132 and the second bearing part 133 to move upwards so as to lift the battery box 20, and the cross bar 211 of the support 21 of the battery box 20 can be hooked without adjusting the extending angle of the mechanical arm 12 and the posture of the connecting assembly 13 in the process of butting the support 21 of the battery box 20, so that the battery box 20 can be butted quickly, and the battery replacing efficiency is improved.

In several embodiments provided in the present disclosure, it will be apparent to those skilled in the art that the present disclosure is not limited to the details of the above-described exemplary embodiments, and can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the disclosure being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Furthermore, it is obvious that the word "comprising" does not exclude other elements or steps, and the singular does not exclude the plural. The terms first, second, etc. are used to denote names, but not to denote any particular order.

Although the present disclosure has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the present disclosure.
