[0008] The detection ends of the two first-in-place sensors correspond to two opposite corners of the four corners of the battery pack, and the horizontal distance between the two first-in-place sensors is relatively far, so that the battery pack can be detected by the two first-in-place sensors even if the placement angle deviation is small, and the active detection capability of the battery swap device in the case of incorrect battery pack placement is improved.

[0009] Preferably, the battery swap device further comprises a second-in-place sensor, which is arranged on the battery swap platform, and the detection end of the second-in-place sensor is arranged in a horizontal direction and corresponds to the side of the battery pack.

[0010] By arranging a second-in-place sensor on the battery swap platform, the second-in-place sensor can detect the side of the battery pack to generate a signal indicating that the battery pack is in place after the battery pack is placed on the battery swap platform, thereby achieving the purpose of detecting the presence or absence of the battery pack. The detection end of the second-in-place sensor is arranged in a horizontal direction and corresponds to the side of the battery pack, so that the second-in-place sensor is arranged at a relatively outer position on the side of the battery pack, which is more convenient for disassembly, debugging, and maintenance of the second-in-place sensor than being arranged at other positions (e.g., below the bottom surface of the battery pack).

[0017] Preferably, the two second-in-place sensors are arranged at the two ends of the battery swap platform along the direction of movement of the horizontal movement mechanism.

[0018] Arranging the two second-in-place sensors at the front and rear ends of the battery swap platform along the direction of movement of the horizontal movement mechanism avoids occupying the space on the left and right sides of the battery swap platform, so that the layout of the battery swap device is more compact.

At the same time, arranging the hollow part on the second sensor support corresponding to the position of the detection end of the second-in-place sensor can avoid affecting the normal detection of the second-in-place sensor.

[0022] Preferably, the battery swap device further comprises a first sensor support extending in a vertical direction, an upper end of the first sensor support is connected with the first-in-place sensor, and a lower end of the first sensor support is detachably connected with the battery swap platform.

[0056] A preferred embodiment is described below in conjunction with the accompanying drawings so as to provide a thorough understanding of the application. In the description, any specific

[0057] As shown in Figure 1 , Figure 2 and Figure 3 , the application provides a battery replacement device 100, which comprises a battery replacement platform 10, a lifting driving mechanism 20 and a horizontal moving mechanism 30. The battery replacement platform 10 is connected with the horizontal moving mechanism 30 through the lifting driving mechanism 20. The battery replacement platform 10 is used for carrying the battery pack 200. The lifting driving mechanism 20 is used for driving the battery replacement platform 10 and the battery pack 200 to lift along the vertical direction A, so as to disassemble and assemble the battery pack 200 relative to the chassis of the electric vehicle. The horizontal moving mechanism 30 is used for driving the battery replacement platform 10 and the battery pack 200 to move horizontally along the advancing direction B, so as to realize the horizontal conveying of the battery pack 200.

[0058] Specifically, as shown in Figure 2 and Figure 3 , the battery replacement platform 10 comprises a battery tray 1, an upper layer plate 2, a lower layer plate 3, a base 4 and a moving mechanism 5. The base 4 is arranged at the lowermost part of the entire battery replacement platform 10, and is used for being connected with the lifting driving mechanism 20. The upper layer plate 2 and the lower layer plate 3 are arranged above the base 4, and are respectively connected with the base 4 through the moving mechanism 5. The moving mechanism 5 is respectively used for driving the upper layer plate 2 and the lower layer plate 3 to reciprocally move along the adjusting direction C, so as to adjust the horizontal position relative to the electric vehicle. The adjusting direction C is perpendicular to the advancing direction B of the horizontal moving mechanism 30. The battery tray 1 is arranged above the upper layer plate 2, and is used for directly contacting with the battery pack 200, so as to realize the purpose of carrying the battery pack 200. The battery tray 1 is connected with the upper layer plate 2 in the vertical direction A, so as to avoid the impact force generated by placing the battery pack 200 from being transmitted to the upper layer plate 2. The moving mechanism 5 adjusts the horizontal position of the upper layer plate 2, so as to align the battery replacement position of the vehicle to be replaced. The lower layer plate 3 is used for being positioned and connected to the vehicle to be replaced. Through the cooperation of the upper layer plate 2 and the lower layer plate 3, the purpose of disassembling and assembling the battery pack 200 relative to the vehicle to be replaced is realized.

[0059] As shown in Figure 4As shown, the battery replacing device 100 further comprises two first position sensors 6, which are both arranged on the battery replacing platform 10, and the detection ends 61 of the first position sensors 6 are arranged upward along the vertical direction. The two first position sensors 6 are used to detect whether the battery pack 200 is properly placed on the battery replacing platform 10. Specifically, by arranging the detection ends 61 of the first position sensors 6 upward along the vertical direction, after the battery pack 200 is placed on the battery replacing platform 10, if both of the first position sensors 6 generate a position signal, it indicates that the placement posture of the battery pack 200 relative to the battery replacing platform 10 is correct. If one or none of the first position sensors generates a position signal, it indicates that the placement posture of the battery pack 200 relative to the battery replacing platform 10 is incorrect (i.e., there is a certain angle between the bottom surface of the battery pack 200 and the bottom surface of the normally placed battery pack 200), and then the posture of the battery pack 200 relative to the battery replacing platform 10 can be determined based on the position signals generated by the two first position sensors 6, so as to actively detect the placement posture of the battery pack 200 relative to the battery replacing platform 10, and avoid damage to the device caused by installing the battery pack 200 in an incorrect posture.

[0060] In this embodiment, the first position sensors 6 are arranged on the base 4 of the battery replacing platform 10, so as to avoid occupying the space of the upper layer plate 2 and the lower layer plate 3, and make the battery replacing device 100 better realize the battery replacing work through the upper layer plate 2 and the lower layer plate 3. At the same time, the first position sensors 6 are arranged on the base 4 with a relatively fixed position, which is also convenient for wiring and accessing of the sensor signal lines.

[0061] In this embodiment, the two first position sensors 6 are arranged corresponding to two opposite corners of the four corners of the battery pack 200. Specifically, please refer to the two solid arrows corresponding to the directions of the detection ends 61 of the two first position sensors 6 in Figure 5 , which shows that the two first position sensors 6 are arranged corresponding to the right upper corner 201a and the left lower corner 201c of the battery pack 200. This structure arrangement scheme can make the horizontal distance between the two first position sensors 6 relatively far, so that the battery pack 200 can be measured by the two first position sensors 6 even if the placement angle deviation is small, and the active detection capability of the battery replacing device 100 in the case of incorrect placement of the battery pack 200 is improved. Of course, in other embodiments, the two first position sensors 6 can be arranged at any position of the battery replacing platform 10 according to actual needs, so as to determine whether the battery pack 200 is properly placed based on the position of the battery pack 200 measured by the two first position sensors 6.

[0062] As shown in Figure 6As shown, the battery replacement device 100 also comprises a second alignment sensor 7, which is also arranged on the battery replacement platform 10, and the detection end 71 of the second alignment sensor 7 is arranged in the horizontal direction and corresponds to the side surface 202 of the battery pack 200. Figure 7 As shown, by arranging the second alignment sensor 7 on the battery replacement platform 10, after the battery pack 200 is placed on the battery replacement platform 10, the second alignment sensor 7 can detect the side surface 202 of the battery pack 200 to generate an alignment signal, thereby achieving the purpose of detecting the presence or absence of the battery pack 200. In this embodiment, the second alignment sensor 7 is arranged on the base 4 of the battery replacement platform 10, thereby avoiding occupying the space of the upper layer plate 2 and the lower layer plate 3, and facilitating the wiring and connection of the sensor signal line.

[0063] In this embodiment, the detection end 71 of the second alignment sensor 7 is arranged in the horizontal direction and corresponds to the side surface 202 of the battery pack 200, so that the arrangement position of the second alignment sensor 7 is located at the side surface 202 of the battery pack 200 and is relatively outward, which is convenient for disassembly, debugging and maintenance of the second alignment sensor 7 compared with being arranged at other positions (for example, below the bottom surface of the battery pack 200).

[0064] Meanwhile, in this embodiment, the first alignment sensor 6 and the second alignment sensor 7 both adopt ultrasonic sensors to achieve the non-contact alignment detection function. Compared with other types of non-contact alignment detection sensors such as photoelectric sensors, the ultrasonic sensor can penetrate smoke, so that the first alignment sensor 6 and the second alignment sensor 7 can also function in the presence of smoke. In other embodiments, the first alignment sensor 6 and the second alignment sensor 7 can also adopt photoelectric sensors or other types of non-contact alignment detection sensors according to actual needs, or adopt microswitches or other types of contact alignment detection sensors to achieve the purpose of detecting whether the battery pack 200 is properly placed and whether it exists.

[0065] As shown, Figure 7 In this embodiment, the height of the second alignment sensor 7 on the battery replacement platform 10 is arranged so that the detection end 71 of the second alignment sensor 7 corresponds to the region close to the upper edge 203 of the side surface 202 of the battery pack 200. By arranging the detection end 71 of the second alignment sensor 7 corresponding to the region close to the upper edge 203 of the side surface 202 of the battery pack 200, the second alignment sensor 7 mechanism also has the function of detecting whether a battery pack 200 of an incorrect specification is mistakenly placed on the battery replacement platform 10. Specifically, when a battery pack 200 of other specifications with a lower height is mistakenly placed on the battery replacement platform 10 of the battery replacement device 100, the detection end 71 of the second alignment sensor 7 cannot detect the side surface 202 of the battery pack 200, so that the second alignment sensor 7 cannot generate an alignment signal, thereby judging that the battery pack 200 of the incorrect specification is mistakenly placed on the battery replacement platform 10.

[0066] As shown in Figure 8 the embodiment, two second-in-position sensors 7 are specifically arranged on the battery replacement platform 10, and the detection ends 71 of the two second-in-position sensors 7 are oppositely arranged (see the direction indicated by the two solid arrows in Figure 8 , so as to correspond to different sides of the battery pack 200. This layout scheme can realize multi-point detection of the battery pack 200 and improve the accuracy of detecting whether the battery pack 200 is present. Specifically, along the traveling direction B of the horizontal moving mechanism 30, the two second-in-position sensors 7 are arranged at the two ends of the battery replacement platform 10, respectively. By arranging the two second-in-position sensors 7 at the front and rear ends of the battery replacement platform 10 along the traveling direction B of the horizontal moving mechanism 30, respectively, the left and right sides of the battery replacement platform 10 are avoided, so that the layout of the battery replacement device 100 is more compact. In other embodiments, the detection ends 71 of the two second-in-position sensors 7 can be arranged towards other sides 202 of the battery pack 200.

[0067] In the embodiment, since two first-in-position sensors 6 are arranged to detect whether the battery pack 200 is properly placed, and two second-in-position sensors 7 are arranged to detect whether the battery pack 200 is present, the two first-in-position sensors 6 and the two second-in-position sensors 7 are arranged to be relatively far away from each other, so as to relatively more objectively and accurately reflect the in-position condition of the battery pack 200. As shown in Figure 9 , the detection ends 61 of the two first-in-position sensors 6 are arranged upwards, so as to correspond to the end corners 201a on the upper right side and the end corners 201c on the lower left side of the battery pack 200, and the detection ends 71 of the two second-in-position sensors 7 are arranged along the horizontal direction, so as to correspond to the side of the end corner 201b on the lower right side and the side of the end corner 201d on the upper left side of the battery pack 200.

[0068] As shown in Figure 4 , the battery replacement device 100 comprises a first sensor support 8, the first sensor support 8 extends along the vertical direction A, and the upper end of the first sensor support 8 is used for connecting with the first-in-position sensor 6, and the lower end of the first sensor support 8 is detachably connected with the base 4 of the battery replacement platform 10. Among them, the upper end of the first sensor support 8 is wrapped on one side of the detection end 61 of the first-in-position sensor 6, and a hollow part 81 is arranged on the first sensor support 8 corresponding to the position of the detection end 61 of the first-in-position sensor 6. By wrapping the first sensor support 8 on one side surface of the first-in-position sensor 6 having the detection end 61, the detection end 61 of the first-in-position sensor 6 is protected, so as to avoid accidental scratching of the detection end 61 of the first-in-position sensor 6 by the battery pack 200 and other parts. At the same time, the hollow part 81 is arranged on the first sensor support 8 corresponding to the position of the detection end 61 of the first-in-position sensor 6, so as to avoid affecting the normal detection of the first-in-position sensor 6.

[0069] As Figure 6 shown, the battery replacing device 100 further comprises a second sensor support 9 extending along the vertical direction A, and the upper end of the second sensor support 9 is used for connecting with the second arrival sensor 7, and the lower end of the second sensor support 9 is detachably connected with the base 4 of the battery replacing platform 10. Wherein, the upper end of the second sensor support 9 is wrapped on one side surface of the detection end 71 of the second arrival sensor 7, and a hollow part 91 is arranged on the second sensor support 9 corresponding to the position of the detection end 71 of the second arrival sensor 7. By wrapping the second sensor support 9 on the side surface of the detection end 71 of the second arrival sensor 7, the detection end 71 of the second arrival sensor 7 is protected, and the detection end 71 of the second arrival sensor 7 is prevented from being accidentally scratched by the battery pack 200 and other parts. At the same time, the hollow part 91 is arranged on the second sensor support 9 corresponding to the position of the detection end of the second arrival sensor 7, so as to avoid affecting the normal detection of the second arrival sensor 7.

[0070] As Figure 2 shown, the battery replacing platform 10 further comprises four buffer contact mechanisms 41 arranged on the base 4 and corresponding to the four corner angles of the battery pack 200, respectively, and the buffer contact mechanism 41 is used for buffering contact with the bottom of the battery pack 200 when the battery pack 200 is placed on the battery replacing platform 10. Figure 4 and Figure 6 As shown in , the first arrival sensor 6 and the second arrival sensor 7 are arranged close to the buffer contact mechanism 41, so as to avoid the battery pack 200 from generating large up and down shaking when placed on the battery replacing platform 10 by using the buffer contact mechanism 41 to contact with the bottom surface of the battery pack 200, and effectively avoid the false alarm of the first arrival sensor 6 and the second arrival sensor 7 caused by the up and down shaking of the bottom surface of the battery pack 200.
