[0047] In various embodiments, for the convenience of description but not limitation of the present disclosure, the term "connection" used in the patent application specification and claims of the present disclosure is not limited to physical or mechanical connection, but can include electrical connection, whether direct or indirect. "Up", "down", "below", "left", "right", and the like are only used to represent relative positional relationships, which change accordingly when the absolute position of the described object changes.

[0048] Figure 1 is a structural schematic diagram of the battery replacement equipment in a state of carrying the vehicle. As shown in Figure 1 , the battery replacement equipment can realize both the function of carrying the vehicle 20 and the function of replacing the battery for the vehicle 20. In the existing parking scenario of the parking garage, the battery replacement equipment can provide the user with the functions of parking and battery replacement, which is conducive to reducing the cost of the garage equipment and improving the parking and charging efficiency of the vehicle 20.

[0049] Figure 2 is a structural schematic diagram of the battery replacement equipment. As shown in Figure 1 and Figure 2 , the battery replacement equipment includes a base body 10, a moving mechanism, a mechanical arm 30, and a battery replacement component. The moving mechanism is used to drive the battery replacement equipment to move along a preset route or carry the vehicle 20 to move; the mechanical arm 30 is used to lift the vehicle 20, and the battery replacement component is used to replace the battery pack 60 for the vehicle 20 after the mechanical arm 30 lifts the vehicle 20.

[0050] The base body 10 is generally in a "C" shape structure, and the end along the walking direction is an open end 13 used to accommodate the vehicle 20. During the process of carrying the vehicle 20, the opening of the open end 13 of the base body 10 faces and moves close to the vehicle 20 until the vehicle 20 is at least partially accommodated in the space of the open end 13. In addition, the end opposite to the open end 13 of the base body 10 is also provided with a battery replacement cavity 12 used to accommodate the battery replacement trolley 51. The base body 10 includes a plurality of battery cavities 11 stacked and arranged and one or more battery cavities 11 used to accommodate the battery pack 60. In the present embodiment, the battery replacement cavity 12 has an opening communicating with the open end 13, and communicates with the open end 13 along the longitudinal direction, so that the battery replacement trolley 51 can move between the space of the open end 13 and the battery replacement cavity 12. The number of the battery cavities 11 can be a plurality of stacked arrangements. In the present embodiment, the battery cavities 11 are arranged on both sides of the battery replacement cavity 12, and each side has two battery cavities 11 in the vertical direction, one of which is used to store the battery pack 60 to be replaced to the vehicle 20 (i.e. the full battery pack 60), and the other is used to store the battery pack 60 replaced from the vehicle 20 (i.e. the low battery pack 60), and each battery cavity 11 communicates with the battery replacement cavity 12, so as to facilitate the battery replacement trolley 51 to exchange the battery pack 60 between the battery replacement cavity 12 and the battery cavity 11.

[0051] The moving mechanism is connected to the base body 10 and is used to move the base body 10. In the embodiment, the moving mechanism includes a plurality of walking wheels 40 arranged at the bottom of the base body 10 and a track (not shown in the figure), wherein the track extends to a parking position for parking the vehicle 20, and the walking wheels 40 rotate under the drive of a walking motor (not shown in the figure) to realize the walking function of the battery replacing device moving along the track. In some embodiments, the battery replacing device moves along the track through the walking wheels 40 to realize linear forward movement or backward movement; in other embodiments, the walking wheels 40 can be steering wheels or be equipped with a steering device to realize the rotating walking of the walking wheels 40, so that the battery replacing device can also turn and walk to the destination (i.e. the preset position) to carry the vehicle 20 to the preset position for parking. In operation, after the vehicle 20 is parked at the parking position, the moving mechanism moves to the parking position along the track through the walking wheels 40, at which time the vehicle 20 is located at the position of the open end 13 of the base body 10. In other embodiments, the moving mechanism can also not need a track, and the walking wheels 40 move according to a preset trajectory to realize the moving function of the battery replacing device. Further, through the movement of the base body 10, the battery replacing device can also realize the function of carrying the vehicle in addition to the battery replacing operation. It is understood by those skilled in the art that the moving mechanism can also be other structures for carrying the vehicle 20 to the open end 13 of the base body 10, such as a vehicle carrier, a movable vehicle loading plate, etc. Those skilled in the art can set the structure of the moving mechanism according to actual needs to realize the movement of at least one of the base body 10 and the vehicle 20, so that the vehicle 20 can be placed at the position of the open end 13 of the base body 10 to realize the battery replacing operation for the vehicle 20.

[0052] The mechanical arm 30 is connected to the base body 10 and is used to clamp the wheels 21 of the vehicle 20 and lift the vehicle 20 to move the vehicle 20. In the embodiment, the number of the mechanical arm 30 is one pair, which is connected to the side wall of the open end 13 of the base body 10, wherein one of the mechanical arms 30 is used to carry the front wheels of the vehicle 20, and the other mechanical arm 30 is used to carry the rear wheels of the vehicle 20, and the lifting of the vehicle 20 is realized through the cooperation of the two mechanical arms 30.

[0053] Figure 3 is a structural schematic view of the mechanical arm 30. As shown in Figure 2 and Figure 3 , the mechanical arm 30 includes a pair of fork arms 31, a horizontal moving component and a lifting component. The pair of fork arms 31 is used to clamp the wheels 21 of the vehicle 20, the horizontal moving component is used to adjust the fork arms 31 to approach or move away along the horizontal direction (i.e. along the length direction of the vehicle 20) to adjust the distance between the pair of fork arms 31. The lifting component is used to pull the fork arms 31 to rise or fall along the vertical direction, so as to lift or lower the vehicle 20.

[0054] The lifting component is connected to the fork arms 31 for lifting the fork arms 31 up or down. As an example, the lifting component includes a moving seat 32, a lifting screw 36 and a lifting motor (not shown in the figure). The moving seat 32 is generally flat and is movably connected to the side wall of the open end 13 of the base body 10 in the vertical direction, so that it can move in the vertical direction along the side wall of the open end 13. The lifting screw 36 is rotatably connected to the side wall of the open end 13 of the base body 10 in the vertical direction, and in this embodiment, the number of lifting screws 36 can be one pair, each threadedly connected to the two ends of the moving seat 32 in the transverse direction. The output shaft of the lifting motor is connected to the lifting screw 36 for driving the lifting screw 36 to rotate, so that the moving seat 32 can be lifted or lowered in the vertical direction.

[0055] The horizontal moving component is connected to the fork arms 31. As an example, the horizontal moving component includes a horizontal moving screw 34, a horizontal moving nut 35 and a horizontal moving motor 33. The horizontal moving screw 34 can be a common screw or a ball screw. The horizontal moving screw 34 is rotatably connected to the moving seat 32 of the base body 10 in the transverse direction. The horizontal moving nut 35 is connected to the fork arm 31, and in this embodiment, each fork arm 31 can have one or more horizontal moving nuts 35. The rotation directions of the horizontal moving nuts 35 of the two fork arms 31 are opposite, and the horizontal moving nuts 35 are threadedly connected to the horizontal moving screw 34. The output shaft of the horizontal moving motor 33 is connected to the horizontal moving screw 34 for driving the horizontal moving screw 34 to rotate. When the horizontal moving motor 33 drives the horizontal moving screw 34 to rotate, the fork arms 31 can be brought closer or farther apart by driving the horizontal moving screw 34 to rotate through the horizontal moving nuts 35 due to the opposite rotation directions of the horizontal moving nuts 35. In other embodiments, the rotation directions of the horizontal moving nuts 35 of the two fork arms 31 can be the same, but the rotation direction of the horizontal moving screw 34 connected to the horizontal moving nuts 35 is opposite, so that the fork arms 31 can still be brought closer or farther apart when the entire horizontal moving screw 34 rotates. In this embodiment, the fork arm 31 is also movably connected to the moving seat 32, for example, it can be movably connected to the moving seat 32 through a roller 311.

[0056] In operation, the moving seat 32 is moved in the vertical direction by the lifting motor to adjust the height of the fork arms 31; the horizontal moving screw 34 is driven to rotate by the horizontal moving motor 33 to adjust the distance between the two fork arms 31, so that the fork arms 31 can adapt to the size of the wheels 21, and when the base body 10 approaches the vehicle 20, the two fork arms 31 can be located on the front and rear sides of the wheels 21, and when the fork arms 31 are moved up, the vehicle 20 can be lifted.

[0057] The battery replacement component is used to move the battery pack 60 of the vehicle 20 to the battery cavity 11, and install the battery pack 60 of the battery cavity 11 to the vehicle 20. Specifically, the battery replacement component includes a battery replacement trolley 51 and a telescopic arm 111. The battery replacement trolley 51 is used to transport the battery pack 60 before the vehicle 20 and the battery cavity 11, and the telescopic arm 111 is used to transfer the battery pack 60 before the battery replacement trolley 51 and the battery cavity 11.

[0058] Figure 4 FIG. 1 is a structural schematic diagram of the battery replacement trolley 51, Figure 5 FIG. 2 is a structural schematic diagram of the battery pack 60. As shown in Figure 4 and Figure 5 The bottom of the battery replacement trolley 51 is provided with a plurality of walking rudders 513, which are used to realize the walking of the battery replacement trolley 51. Specifically, the battery replacement trolley 51 moves between the vehicle 20 below the open end 13 and the battery replacement cavity 12 through the walking rudders. The top of the battery replacement trolley 51 has a planar area for carrying the battery pack 60, which is provided with a locking piece 511 and a guide piece 512. The locking piece 511 corresponds to the lock hole 61 of the battery pack 60, and can realize the locking or unlocking of the battery pack 60 to the planar area of the battery replacement trolley 51. The guide piece 512 extends in the vertical direction, and is used to guide the battery pack 60 to move to the planar area in the vertical direction. In work, when the mechanical arm 30 lifts the vehicle 20, the battery replacement trolley moves below the vehicle 20 to exchange the battery pack 60 with the vehicle 20, unlocks the battery pack 60 from the vehicle 20 through the locking piece 511, and after carrying the battery pack 60 on the planar area under the guidance of the guide piece, locks the battery pack 60 to the battery replacement trolley 51. Then, the battery replacement trolley 51 moves to the battery replacement cavity 12 to transfer the battery pack 60 with the battery cavity 11, moves the battery pack 60 with low power to the battery cavity 11, and completes the battery replacement action.

[0059] In some embodiments, the battery replacement device further includes a battery replacement arm 50 located in the battery replacement cavity 12. The battery replacement arm 50 is used to lift the battery replacement trolley 51, and the height of the battery replacement trolley 51 corresponds to the battery cavity 11 to move the battery pack 60 between the battery cavity 11. In the case where the battery pack 60 does not need to be replaced, the battery replacement arm 50 loads the battery replacement trolley 51, so that the battery replacement trolley 51 can be separated from the ground and move together with the base body 10. The structure of the battery replacement arm 50 is similar to that of the mechanical arm 30, which will not be described here.

[0060] The battery replacement component further comprises a telescopic arm 111 for moving the battery pack 60 between the battery replacement trolley 51 and the battery cavity 11. The telescopic arm 111 is arranged on the battery replacement trolley 51 or the battery cavity 11, and is used to extend or retract when carrying the battery pack 60 to move the battery pack 60 to the battery cavity 11 or the battery replacement trolley 51. In this embodiment, the telescopic arm 111 is arranged on the bottom surface of the battery cavity 11 to carry the battery pack 60. In this way, the battery pack 60 can be sent out of the battery cavity 11 to the battery replacement trolley 51 after the telescopic arm 111 is extended, or the battery pack 60 can be carried after the telescopic arm 111 is extended below the battery pack 60 on the battery replacement trolley 51, and the battery pack 60 is moved to the battery cavity 11 by retracting the telescopic arm 111 to the battery cavity 11. The telescopic arm 111 can be a telescopic fork, a linear motor, or a nut-screw structure, and those skilled in the art can select a suitable telescopic arm 111 to achieve the telescopic function, and the present application does not limit this.

[0061] Figure 6 is a schematic diagram of the process of storing the battery pack 60 by the battery replacement trolley 51. As shown in Figure 6 , the battery replacement trolley 51 stores the battery pack 60 to move the battery pack 60 from the battery replacement trolley 51 to the battery cavity 11. First, the battery replacement trolley 51 moves from the vehicle 20 to load the battery pack 60 into the battery replacement cavity 12, at this time, the battery cavity 11 is located on both sides of the battery replacement cavity 12. Then, the battery replacement arm 50 Figure 6 (not shown in the figure) lifts the battery replacement trolley 51 to rise, so that the height of the battery pack 60 of the battery replacement trolley 51 corresponds to the battery cavity 11 above (the empty battery cavity 11). Then, the telescopic arm 111 extends from the battery cavity 11 to the bottom of the battery pack 60, and the battery replacement trolley 51 can be slightly moved downward, so that the battery pack 60 is carried on the telescopic arm 111. Then, the telescopic arm 111 retracts, and the battery pack 60 is moved horizontally to the battery cavity 11. Finally, the telescopic arm 111 retracts, and the battery pack 60 is completely moved into the battery cavity 11, and the storing action of the battery pack 60 is completed.

[0062] Figure 7 is a schematic diagram of the process of taking the battery pack 60 by the battery replacement trolley 51. The purpose of the battery replacement trolley 51 taking the battery pack 60 is to carry the battery pack 60 from the battery cavity 11 to the battery replacement trolley 51. As shown in Figure 7As shown, in the initial state, the battery cavity 11 stores a full battery pack 60 for replacement to the vehicle 20, and the battery replacement trolley 51 is in an idle state without loading the battery pack 60. Then, the battery replacement arm 50 drags the battery replacement trolley 51 to move in the vertical direction, so that the height of the battery replacement trolley 51 corresponds to the battery cavity 11 below. Next, the telescopic arm 111 extends towards the battery replacement trolley 51, moves the battery pack 60 from the battery cavity 11 to the upper side of the battery replacement trolley 51, and then the battery replacement arm 50 can drag the battery replacement trolley 51 to move slightly upward to carry the battery pack 60. Finally, the telescopic arm 111 retracts to the battery cavity 11, and the battery replacement arm 50 drags the battery replacement trolley 51 to move downward until the battery replacement trolley 51 lands to load the battery pack 60 to move to the lower side of the vehicle 20, and completes the action of taking the battery pack 60.

[0063] Figure 8 is a flowchart of the battery replacement method. The following describes the battery replacement method based on the above-mentioned battery replacement device. Figure 8 The battery replacement method based on the above-mentioned battery replacement device is described in detail. As shown in the flowchart, Figure 8 The battery replacement method includes the following steps.

[0064] Step S801: After the vehicle 20 is parked at a predetermined position, the moving mechanism drags the open end 13 of the base body 10 to approach the vehicle 20, and at the same time, the transverse motor 33 drags the fork arms 31 to move transversely to adapt to the position of the wheels 21 of the vehicle 20.

[0065] Step S802: After the vehicle 20 is contained in the open end 13, the mechanical arm 30 clamps the wheels 21 of the vehicle 20. Specifically, a pair of fork arms 31 of a mechanical arm 30 is located on the front and rear sides of the front wheels, and a pair of fork arms 31 of another mechanical arm 30 is located on the front and rear sides of the rear wheels. Then, the transverse motor 33 rotates to adjust the distance between the fork arms 31 to the appropriate position.

[0066] Step S803: The mechanical arm 30 lifts the vehicle 20 to a predetermined height. In this step, the lifting component of the mechanical arm 30 lifts the fork arms 31 to lift the vehicle 20 to the appropriate height.

[0067] Step S804: The battery replacement component moves the battery pack 60 of the vehicle 20 to the battery cavity 11 of the base body 10, and moves the battery pack 60 of the battery cavity 11 of the base body 10 to the vehicle 20. In this step, first, the battery replacement trolley 51 completes the battery storage action. Specifically, the battery replacement trolley 51 of the battery replacement component moves from the battery replacement cavity 12 of the base body 10 to the lower side of the vehicle 20, and moves the battery pack 60 of the vehicle 20 to the battery replacement trolley 51. Then, the battery replacement trolley 51 loaded with the battery pack 60 moves to the battery replacement cavity 12, and moves the battery pack 60 of the battery replacement trolley 51 to the battery cavity 11. During the movement of the battery pack 60, the mechanical arm 30 extends from the battery cavity 11 to the lower side of the battery pack 60 of the battery replacement trolley 51, the battery replacement trolley 51 is lowered so that the battery pack 60 is carried by the telescopic arm 111, then the telescopic arm 111 is retracted to move the battery pack 60 to the battery cavity 11, and the telescopic arm 111 extends to carry the battery pack 60 until the battery pack 60 is above the battery replacement trolley 51, the battery replacement trolley 51 is lifted to carry the battery pack 60, the telescopic arm 111 is retracted, and the movement of the battery pack 60 to the battery replacement trolley 51 is completed. Then, the battery replacement trolley 51 moves to the lower side of the vehicle 20, and moves the battery pack 60 to the vehicle 20. Then, the battery replacement trolley 51 completes the battery taking action, and the action process is similar and will not be described here.

[0068] Step S805: The moving mechanism drives the base body 10 to move, and moves the vehicle 20 to a predetermined position. Those skilled in the art know that this step can be implemented before the battery pack 60 replacement action, or the battery replacement action can be implemented after the vehicle 20 is moved to the predetermined position.

[0069] The above-mentioned battery replacement device and battery replacement method lift the vehicle 20 by clamping the wheels 21 of the vehicle 20 by the mechanical arm 30, and exchange the battery pack 60 of the vehicle 20 and the battery pack 60 accommodated in the battery cavity 11 by the battery replacement component, to complete the battery replacement work of the vehicle 20. The battery replacement process does not depend on a specific place and other equipment, and realizes a simple and low-cost way to provide battery replacement service for vehicles in a general garage environment.

[0070] Further, the above-mentioned battery replacement device can also move the vehicle 20 by the moving mechanism to complete the moving action of the vehicle 20, so that the battery replacement work of the vehicle 20 can be completed while parking in the garage, and the parking and battery replacement needs of the vehicle can be met in the garage, which also effectively improves the utilization rate of the battery replacement device.
