[0007] In the battery replacing device, the unlocking mechanism is arranged at the side of the battery carrying plate to utilize the side space of the battery carrying plate to accommodate the unlocking mechanism, effectively solving the problem that the unlocking mechanism is too high in size and can only be arranged on the upper surface of the base. Meanwhile, the battery carrying plate is used to carry the battery pack and adjust the position relative to the locking mechanism of the electric vehicle under the driving of the displacement adjusting mechanism, the unlocking mechanism is connected with the battery carrying plate to adjust the position synchronously with the battery carrying plate to realize the alignment with the locking mechanism of the electric vehicle, so it is not necessary to additionally arrange a driving mechanism to adjust the horizontal position of the unlocking mechanism, effectively simplifying the structure of the battery replacing device and the battery replacing control process.

[0010] Preferably, the adapter plate further has a reinforcing member, two side surfaces of the reinforcing member are connected to the first mounting surface and the second mounting surface respectively.

[0011] The first mounting surface and the second mounting surface of the adapter plate are structurally reinforced through the reinforcing member, avoiding deformation in the process of continuous use.

[0012] Preferably, the battery replacing platform further comprises a battery tray, the battery tray is located above the battery carrying plate, the battery tray is used to directly carry the battery pack, in the vertical direction, the battery tray is elastically connected with the battery carrying plate, and in the horizontal direction, the battery tray is positioningly connected with the battery carrying plate.

[0015] The battery tray and the battery carrying plate are elastically connected in the vertical direction to realize buffering, avoiding that the impact force of placing the battery pack to the battery tray is rapidly transmitted to the battery carrying plate to cause the components arranged on the battery carrying plate (such as the unlocking mechanism) to be damaged by the impact.

[0016] Meanwhile, the battery tray and the battery carrier plate are connected in the horizontal direction, so that the horizontal driving force of the displacement adjustment mechanism can be directly transmitted to the battery tray, thereby achieving the purpose of horizontal position adjustment.

[0017] Preferably, the unlocking mechanism is a two-stage lock unlocking mechanism, and the battery swap platform further comprises a one-stage lock unlocking mechanism, which is arranged on the upper surface of the battery carrier plate and does not interfere with the battery tray in the horizontal direction.

[0018] By arranging the one-stage lock unlocking mechanism and the two-stage lock unlocking mechanism on the battery carrier plate, multi-stage unlocking relative to the locking mechanism of the electric vehicle is achieved, and the misunlocking situation is avoided. The one-stage lock unlocking mechanism is used for pre-unlocking, and does not need to be provided with a driving mechanism for driving the top rod to move up and down, so the structure is simpler than that of the two-stage lock unlocking mechanism, and therefore there is sufficient height space on the upper surface of the battery carrier plate.

[0022] By arranging the connecting rod structure, the horizontal driving force output by the power source is converted into the vertical movement of the top rod through the force transmission of the single rod in the axial direction. Compared with other transmission schemes, the reliability of the transmission through the connecting rod is higher. Moreover, since the structure is relatively simple, the height dimension of the connecting rod structure can be avoided to affect the setting space of the unlocking mechanism on the side of the battery carrier plate.

[0030] In the case of arranging both the first position sensor and the second position sensor, if one of the position sensors detects the position, and the other position sensor does not detect the position, it indicates that one of the position sensors is damaged. Therefore, arranging both the position sensors can improve the detection reliability.

[0073] The utility model will be described below with a preferred embodiment and in combination with the drawings.

[0074] Example 1

[0075] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a battery swapping device 100, which includes a battery swapping platform 10, a lifting drive mechanism 20, and a horizontal movement mechanism 30. The battery swapping platform 10 is connected to the horizontal movement mechanism 30 via the lifting drive mechanism 20. The battery swapping platform 10 carries a battery pack 200. The lifting drive mechanism 20 drives the battery swapping platform 10 and the battery pack 200 to move vertically A and detach the battery pack 200 relative to the chassis of an electric vehicle. The horizontal movement mechanism 30 drives the battery swapping platform 10 and the battery pack 200 to move horizontally along a traveling direction B, thereby achieving horizontal transport of the battery pack 200.

[0076] Specifically, such as Figure 2 and Figure 3 As shown, the battery swapping platform 10 includes a battery tray 1, a battery support plate 2, a vehicle connection plate 3, a base 4, a displacement adjustment mechanism 5, and an unlocking mechanism 6. The base 4 is located at the bottom of the entire battery swapping platform 10 and is connected to the lifting drive mechanism 20. The battery support plate 2 and the vehicle connection plate 3 are located above the base 4 and are connected to the base 4 via the displacement adjustment mechanism 5. The displacement adjustment mechanism 5 drives the battery support plate 2 and the vehicle connection plate 3 to reciprocate along the adjustment direction C to adjust their horizontal position relative to the electric vehicle. The adjustment direction C is perpendicular to the travel direction B of the horizontal movement mechanism 30. The battery tray 1 is located above the battery support plate 2 and is used to directly contact the battery pack 200 to support the battery pack 200. The battery tray 1 and the battery support plate 2 are elastically connected in the vertical direction A to prevent the impact force generated by placing the battery pack 200 from being transmitted to the battery support plate 2. Simultaneously, the battery tray 1 and the battery support plate 2 are positioned and connected in the horizontal adjustment direction C to transmit the horizontal displacement of the battery support plate 2 to the battery tray 1, thereby adjusting the horizontal position of the battery pack 200. The displacement adjustment mechanism 5 adjusts the horizontal position of the battery support plate 2 so that the battery pack 200 can be aligned with the battery swapping position of the vehicle to be swapped. The vehicle connecting plate 3 is used for positioning and connecting to the vehicle to be swapped. Through the cooperation of the battery support plate 2 and the vehicle connecting plate 3, the purpose of attaching and detaching the battery pack 200 from the vehicle to be swapped is achieved. The unlocking mechanism 6 drives the push rod to move upward in the vertical direction A to open the locking linkage of the locking mechanism used to fix the battery pack 200 on the electric vehicle, thus achieving the unlocking purpose.

[0077] like Figure 3 and Figure 4As shown, in the embodiment, two unlocking mechanisms 6 are respectively arranged on the left side and the right side of the battery carrying plate 2 along the traveling direction B and are respectively connected with the battery carrying plate 2. By arranging the unlocking mechanisms 6 on the side of the battery carrying plate 2, the unlocking mechanisms 6 are accommodated in the side space of the battery carrying plate 2, effectively solving the problem that the unlocking mechanisms 6 are too large in height and can only be arranged on the upper surface of the base 4.

[0078] Meanwhile, the battery carrying plate 2 is used to carry the battery pack 200 and is driven by the displacement adjusting mechanism 5 to adjust the position of the battery carrying plate 2 relative to the locking mechanism of the electric vehicle along the adjusting direction C. By connecting the unlocking mechanisms 6 with the battery carrying plate 2, the unlocking mechanisms 6 can be adjusted in position synchronously with the battery carrying plate 2 to realize the alignment with the locking mechanism of the electric vehicle, so that it is not necessary to additionally arrange other driving mechanisms to separately adjust the horizontal position of the unlocking mechanisms 6, which can effectively simplify the structure of the battery swap device and make the battery swap control process relatively simple.

[0079] Specifically, in the embodiment, the number of the unlocking mechanisms 6 is two, which are distributed on the two side surfaces of the battery carrying plate 2. In other embodiments, the number of the unlocking mechanisms 6 can also be arranged according to actual needs.

[0080] As shown, Figure 5 The unlocking mechanisms 6 are arranged below the battery tray 1. In order to avoid the battery tray 1 affecting the upward movement of the ejector rods 61 of the unlocking mechanisms 6, first hollow parts 11 are arranged on both sides of the battery tray 1 to correspond to the positions of the ejector rods 61 of the two unlocking mechanisms 6, so that the ejector rods 61 can extend upward from the first hollow parts 11 and avoid interfering with the battery tray 1. In other embodiments, the setting positions of the unlocking mechanisms 6 can also be adjusted, or the size of the battery tray 1 can be reduced, so that the ejector rods 61 of the unlocking mechanisms 6 are arranged in a staggered manner in the horizontal direction with the battery tray 1.

[0081] In the embodiment, the battery pack 200 is internally provided with an adapter rod in the vertical direction A. After the ejector rods 61 extend upward through the first hollow parts 11 of the battery tray 1, the ejector rods 61 contact the bottom of the adapter rod of the battery pack 200, push the adapter rod to move upward, and the top end of the adapter rod contacts the locking mechanism of the electric vehicle to realize unlocking.

[0082] In the embodiment, as shown, Figure 6 The battery swap platform 10 further comprises two first-level lock unlocking mechanisms 8. The first-level lock unlocking mechanisms 8 are relatively simple in structure, the ejector rods 81 of the first-level lock unlocking mechanisms 8 are located at a high position and do not have the ability to move up and down, so that the first-level lock unlocking mechanisms 8 can be arranged on the upper surface of the battery carrying plate 2.

[0083] On the basis of the above-mentioned unlocking mechanism 6 as a two-stage lock unlocking mechanism, a one-stage lock unlocking mechanism 8 is further provided to realize multi-stage unlocking of the locking mechanism of the electric vehicle and avoid the occurrence of false unlocking. The one-stage lock unlocking mechanism 8 is used for pre-unlocking, and does not need to be provided with a driving mechanism for driving the top rod 81 to move up and down. The structure is simpler than that of the two-stage lock unlocking mechanism (the unlocking mechanism 6), and therefore has sufficient height space on the upper surface of the battery carrying plate 2.

[0084] As shown in Figure 5 , the one-stage lock unlocking mechanism 8 is also arranged below the battery tray 1, and the second hollow part 12 is arranged on both sides of the battery tray 1, so that the top rod 81 of the two one-stage lock unlocking mechanisms 8 can extend from the second hollow part 12. In other embodiments, the setting position of the one-stage lock unlocking mechanism 8 can also be adjusted, or the size of the battery tray 1 can be reduced, so that the top rod 81 of the one-stage lock unlocking mechanism 8 is arranged in a staggered manner with the battery tray 1 in the horizontal direction.

[0085] The present embodiment further provides a preferred structure setting scheme of the unlocking mechanism 6: as shown in Figure 7 and Figure 8 , the unlocking mechanism 6 includes a top rod 61, a transmission part 62, a power source 63 and a mechanism frame 67. The mechanism frame 67 is used for accommodating the transmission part 62 and protecting the linkage structure of the transmission part 62. The top rod 61 is arranged in the vertical direction A and connected with the power source 63 through the transmission part 62. The transmission part 62 is used for transmitting the driving force of the power source 63 in the first horizontal direction (i.e. the adjustment direction C in the present embodiment) to the top rod 61 and driving the top rod 61 to move up and down in the vertical direction A. The power source 63 of the unlocking mechanism 6 outputs the driving force outward along the horizontal adjustment direction C, which can avoid the height dimension of the power source 63 being too large to affect the setting space of the unlocking mechanism 6 on the side surface of the battery carrying plate 2, and realize compact layout. At the same time, the transmission part 62 changes the driving force of the power source 63 along the adjustment direction C to the vertical direction A and transmits it to the top rod 61, so as to realize the lifting of the top rod 61 and the unlocking purpose. In the present embodiment, the power source 63 is realized by an electric push rod, which utilizes the high position accuracy of the electric push rod to improve the unlocking accuracy of the unlocking mechanism 6.

[0086] Specifically, the transmission part 62 comprises a connecting rod 621, a first guide rail 622 and a second guide rail 623. The first guide rail 622 is arranged along the horizontal adjustment direction C, and the second guide rail 623 is arranged along the vertical direction A. The first end 6211 of the connecting rod 621 is movably connected to the power source 63 and can reciprocate along the adjustment direction C on the first guide rail 622, so that the first guide rail 622 guides the first end 6211 of the connecting rod 621. The second end 6212 of the connecting rod 621 is movably connected to the top rod 61 and can reciprocate along the vertical direction A on the second guide rail 623. In this embodiment, the transmission part 62 transmits the force output by the power source 63 to the top rod 61 by single-rod axial force transmission, and converts the horizontal driving force output by the power source 63 into vertical movement of the top rod 61. Compared with other transmission schemes, the reliability of the transmission through the connecting rod 621 is higher. Moreover, due to the relatively simple structure, the height dimension of the connecting rod 621 structure can be avoided to affect the installation space of the unlocking mechanism 6 on the side of the battery carrying plate 2. In this embodiment, as shown in Figure 7 the first guide rail 622 and the second guide rail 623 are formed on the side of the mechanism frame 67. The first end 6211 of the connecting rod 621 is accommodated in the waist hole extending along the adjustment direction C on the side of the mechanism frame 67 to form the first guide rail 622 and guide the first end 6211 of the connecting rod 621. The second end 6212 of the connecting rod 621 is accommodated in the waist hole extending along the vertical direction A on the side of the mechanism frame 67 to form the second guide rail 623 and guide the second end 6212 of the connecting rod 621. By guiding the two ends of the two rods by the mechanism frame 67, the structure of the unlocking mechanism 6 can be more compact.

[0087] In addition, the mechanism frame 67 is also provided with a guide 64 on the top thereof, and the top rod 61 passes through the through hole of the guide 64 to limit the horizontal movement degree of freedom of the top rod 61, so that the top rod 61 can keep accurate vertical movement and improve the unlocking accuracy.

[0088] In this embodiment, as shown in Figure 8 the main body of the mechanism frame 67 is composed of a frame structure, and the connecting rod 621 of the transmission part 62 is arranged in the mechanism frame 67. As can be seen from the figure, the left and right sides of the mechanism frame 67 are open. The left side of the mechanism frame 67 is open to allow the power source 63 to extend into the connecting rod 621 for connection. The right side of the mechanism frame 67 is open to facilitate the installation of the connecting rod 621 and the maintenance of the connecting rod 621. In addition, the bottom of the mechanism frame 67 in this embodiment extends towards the power source 63 and is connected to the power source 63, so as to fix the power source 63 by the structure frame and integrate the structure of the entire unlocking mechanism 6.

[0089] As shown in Figure 7As shown, the unlocking mechanism 6 further comprises a first to-position sensor 65 and a second to-position sensor 66. Among them, the first to-position sensor 65 is arranged at the first guide rail 622 of the side of the mechanism frame 67 and close to the first end 6211 of the connecting rod 621, and the first to-position sensor 65 is used to detect the to-position condition of the first end 6211 of the connecting rod 621. And the second to-position sensor 66 is arranged at the second guide rail 623 of the side of the mechanism frame 67 and close to the second end 6212 of the connecting rod 621, and the second to-position sensor 66 is used to detect the to-position condition of the second end 6212 of the connecting rod 621. By arranging the first to-position sensor 65 or the second to-position sensor 66, the to-position condition of the first end 6211 or the second end 6212 of the connecting rod 621 is detected respectively. Since the to-position condition of the first end 6211 or the second end 6212 of the connecting rod 621 can directly reflect the jacking condition of the jacking rod 61, the active detection of the jacking rod 61 to the jacking position can be realized.

[0090] Among them, in the case of simultaneously arranging the first to-position sensor 65 and the second to-position sensor 66, if one of the to-position sensors detects the to-position condition, and the other to-position sensor does not detect the to-position condition, it indicates that one of the to-position sensors is damaged. Therefore, the simultaneous arrangement of the two to-position sensors can improve the detection reliability. Of course, in other embodiments, only the first to-position sensor 65 can be arranged to detect the to-position condition of the first end 6211 of the connecting rod 621, or only the second to-position sensor 66 can be arranged to detect the to-position condition of the second end 6212 of the connecting rod 621 according to actual needs.

[0091] As shown in Figure 4 and Figure 9 As shown, the battery replacement platform 10 in the embodiment further comprises a adapter plate 7, and the reliable connection between the unlocking mechanism 6 and the battery carrying plate 2 is realized through the adapter plate 7. Specifically, as shown in Figure 10 the adapter plate 7 has a first mounting surface 71 and a second mounting surface 72 arranged at an angle, wherein the first mounting surface 71 is used to connect the position close to the side surface of the upper surface of the battery carrying plate 2, and the second mounting surface 72 is used to connect the side surface of the mechanism frame 67 of the unlocking mechanism 6. Among them, the first mounting surface 71 of the adapter plate 7 is connected at the position close to the side surface of the upper surface of the battery carrying plate 2, which is convenient for disassembly and maintenance between the adapter plate 7 and the battery carrying plate 2. In addition, as shown in Figure 11 two reinforcing members 73 are further arranged on each adapter plate 7, and the two sides of each reinforcing member 73 are connected on the first mounting surface 71 and the second mounting surface 72 of the adapter plate 7, so as to use the reinforcing member 73 to strengthen the structure of the first mounting surface 71 and the second mounting surface 72 of the adapter plate 7, and avoid deformation in the process of continuous use.
