[0003] With the rapid development of new energy electric vehicles, a quick-swap electric vehicle has emerged. This electric vehicle no longer needs to wait for several hours to charge the battery. It only needs to remove the low-power battery from the car and reinstall a fully charged battery. As a place dedicated to providing battery quick-swap services for electric vehicles, battery swap stations have been established and operated on a large scale across the country.

[0004] However, current battery swap stations are only tailored to the different models and battery pack specifications of each automobile manufacturer. Different automobile manufacturers use different locking methods for battery packs.

[0131] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0132] The first locking mechanism and the second locking mechanism involved in the present invention are illustrated using Chinese patent application numbers 2016110412204 and 2017112736024 as examples. However, the two locking mechanisms in the multifunctional battery exchange device of the present invention are not limited to the specific structures in the above-mentioned prior art, and can also be applied to other types of battery locking structures.

[0133] Example 1

[0134] Different types of battery packs usually use different locking mechanisms when installed with electric vehicles or charging equipment. Figure 1As shown, the present invention provides a multifunctional battery swapping device, which is used to disassemble and assemble battery packs locked by different locking mechanisms. Specifically, the battery swapping device includes a first disassembly and assembly mechanism 1 and a second disassembly and assembly mechanism 2. The first disassembly and assembly mechanism 1 corresponds to the first locking mechanism, and the second disassembly and assembly mechanism 2 corresponds to the second locking mechanism. The first disassembly and assembly mechanism 1 is used to disassemble and assemble the first battery pack locked by the first locking mechanism, and the second disassembly and assembly mechanism 2 is used to disassemble and assemble the second battery pack locked by the second locking mechanism.

[0135] By configuring the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 on a battery swapping device, the battery swapping device can be used for disassembly and assembly of two types of battery packs at the same time, thereby improving the compatibility of the battery swapping device, thereby improving the battery swapping efficiency, improving the compatibility of the battery swapping station, and reducing the manufacturing cost of the battery swapping station. Different types of battery packs, in addition to differences in the specifications and sizes of the battery packs, also include differences in the types of locking mechanisms of the battery packs on the corresponding electric vehicles.

[0136] Among them, the battery exchange device also includes a control mechanism, which is used to receive the type of locking mechanism of the battery pack to be disassembled and assembled, and the control mechanism is also used to control the corresponding disassembly and assembly mechanism to complete the disassembly and assembly of the battery pack. For example, when the control mechanism receives that the type of locking mechanism of the battery pack to be disassembled and assembled is the first locking mechanism, that is, the battery pack is the first battery pack, the control mechanism controls the first disassembly and assembly mechanism 1 to unlock or lock the first locking mechanism, so that the first battery pack can be disassembled or installed; when the control mechanism receives that the type of locking mechanism of the battery pack to be disassembled and assembled is the second locking mechanism, the control mechanism controls the second disassembly and assembly mechanism 2 to unlock or lock the second locking mechanism, so that the second battery pack can be disassembled or installed.

[0137] like Figure 1 As shown, the battery swap device also includes a base 3, and the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 are detachably mounted on the base 3. Through the detachable connection between the first disassembly and assembly mechanism 1, the second disassembly and assembly mechanism 2 and the base 3, the battery swap device can be installed with the first disassembly and assembly mechanism 1 or the second disassembly and assembly mechanism 2 separately, so that the battery swap device can be used for the disassembly and assembly of the first battery pack or the second battery pack separately; the battery swap device can also be installed with the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 at the same time, so that the battery swap device is compatible with the disassembly and assembly of the first battery pack and the second battery pack.

[0138] like Figure 1 As shown, the positions of the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 on the base 3 are relatively determined. Relative to the first disassembly and assembly mechanism 1, the area where the second disassembly and assembly mechanism 2 is located is an avoidance area, that is, the second disassembly and assembly mechanism 2 does not affect the action of the first disassembly and assembly mechanism 1 to disassemble and assemble the battery pack; relative to the second disassembly and assembly mechanism 2, the area where the first disassembly and assembly mechanism 1 is located is an avoidance area, that is, the first disassembly and assembly mechanism 1 does not affect the action of the second disassembly and assembly mechanism 2 to disassemble and assemble the battery pack.

[0139] In other embodiments, there may be multiple disassembly and assembly mechanisms, and the multiple disassembly and assembly mechanisms correspond to battery packs locked by multiple different locking mechanisms. The number of disassembly and assembly mechanisms is determined according to the number of locking mechanisms that the battery exchange device needs to be compatible with.

[0140] The multifunctional battery swapping equipment is applied to the battery swapping station, so that the battery swapping station can be compatible with the disassembly and assembly of various types of battery packs. Figure 2 As shown, the battery swap station includes a battery compartment 100, a first battery swap device 200 and a second battery swap device 300. The battery compartment 100 stores a first battery pack corresponding to a first locking mechanism and a second battery pack corresponding to a second locking mechanism. The first battery swap device 200 and the second battery swap device 300 are multifunctional battery swap devices. The first battery swap device 200 is used to remove a low-power battery pack from an electric vehicle 400, and the second battery swap device 300 is used to install a fully charged battery pack on the electric vehicle 400.

[0141] The first battery exchange device 200 and the second battery exchange device 300 are set as multifunctional battery exchange devices, so that the first battery exchange device 200 and the second battery exchange device 300 can be used to replace the first battery pack or the second battery pack at the same time. When the battery pack to be replaced is the first battery pack, while the first battery exchange device 200 removes the depleted first battery pack from the electric vehicle 400, the second battery exchange device 300 can take out the fully charged first battery pack from the battery compartment 100 and wait on the side; after the first battery exchange device 200 completes the removal of the first battery pack, the second battery exchange device 300 immediately installs the first battery pack on the electric vehicle 400. When the battery pack to be replaced is the second battery pack, while the first battery exchange device 200 removes the depleted second battery pack from the electric vehicle 400, the second battery exchange device 300 can take out the fully charged second battery pack from the battery compartment 100 and wait on the side; after the first battery exchange device 200 completes the removal of the second battery pack, the second battery exchange device 300 immediately installs the second battery pack on the electric vehicle 400. It can be seen that when the first battery exchange device 200 and the second battery exchange device 300 are compatible with the replacement of two battery packs, the battery exchange efficiency can be significantly improved.

[0142] The first battery exchange device 200 and the second battery exchange device 300 may also be provided with a variety of disassembly and assembly mechanisms to cope with various types of battery packs in battery exchange stations.

[0143] Example 2

[0144] The structure of the multifunctional battery exchange device of Example 2 is substantially the same as that of Example 1, except that the position between the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 can be adjusted by an avoidance mechanism. That is, the battery exchange device is also provided with an avoidance mechanism, which moves the idle disassembly and assembly mechanism to the avoidance position, and the disassembly and assembly mechanism at the avoidance position does not affect the action of other disassembly and assembly mechanisms to disassemble and assemble the battery pack.

[0145] In actual disassembly and assembly needs, the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 may interfere with each other during the disassembly and assembly process. In this case, when the first disassembly and assembly mechanism 1 is disassembling and assembling the battery pack, the second disassembly and assembly mechanism 2 needs to be moved to an avoidance position so that the second disassembly and assembly mechanism 2 does not affect the disassembly and assembly action of the first disassembly and assembly mechanism 1; and when the second disassembly and assembly mechanism 2 is disassembling and assembling the battery pack, the first disassembly and assembly mechanism 1 needs to be moved to an avoidance position so that the first disassembly and assembly mechanism 1 does not affect the disassembly and assembly action of the second disassembly and assembly mechanism 2.

[0146] The avoidance mechanism of this embodiment is as follows: Figure 3 The avoidance mechanism 4 includes a flip body 41 and a rotating shaft 42. The flip body 41 rotates around the axis of the rotating shaft 42 to achieve flipping. The flip body 41 is provided with a first mounting surface 411 and a second mounting surface 412 around the circumference. The first disassembly and assembly mechanism 1 is mounted on the first mounting surface 411, and the second disassembly and assembly mechanism 2 is mounted on the second mounting surface 412. The flip body 41 rotates the idle disassembly and assembly mechanism to the avoidance position during the flipping process.

[0147] For example, when the first disassembly and assembly mechanism 1 is used to disassemble and assemble the battery pack, the flip body 41 flips to make the first disassembly and assembly mechanism 1 flip to the disassembly and assembly position, and the second disassembly and assembly mechanism 2 flips to the avoidance position. The first disassembly and assembly mechanism 1 located at the disassembly and assembly position can disassemble and assemble the battery pack, and the second disassembly and assembly mechanism 2 located at the avoidance position does not affect the disassembly and assembly action of the first disassembly and assembly mechanism 1. For another example, when the second disassembly and assembly mechanism 2 is used to disassemble and assemble the battery pack, the flip body 41 flips to make the second disassembly and assembly mechanism 2 flip to the disassembly and assembly position, and the first disassembly and assembly mechanism 1 flips to the avoidance position. The second disassembly and assembly mechanism 2 located at the disassembly and assembly position can disassemble and assemble the battery pack, and the first disassembly and assembly mechanism 1 located at the avoidance position does not affect the disassembly and assembly action of the second disassembly and assembly mechanism 2.

[0148] In other embodiments, the flip body may have several mounting surfaces, each disassembly mechanism is separately mounted on one mounting surface, and the flip body rotates the idle disassembly mechanism to an avoidance position during the flipping process. The number of disassembly mechanisms is determined according to the number of locking mechanisms that the battery exchange device needs to be compatible with.

[0149] Example 3

[0150] The structure of the multifunctional battery exchange device of Example 3 is substantially the same as that of Example 1, except that:

[0151] like Figure 4 As shown, the first disassembly and assembly mechanism 1 includes an upper plate 11, a lower plate 12, a first positioning mechanism and a push rod 14. The upper plate 11 is located above the lower plate 12, and the upper plate 11 can move relative to the lower plate 12; the first positioning mechanism in this embodiment is a first positioning fork 13, and the first positioning fork 13 is arranged on the upper plate 11, and the first positioning fork 13 is used to position the battery pack; the push rod 14 is arranged on the lower plate 12, and the push rod 14 is used to unlock the first locking mechanism 50.

[0152] Figure 5 The first locking mechanism 50 corresponding to the first disassembly and assembly mechanism 1 is shown. The first locking mechanism 50 includes a lock link 501, a lock base 502 and a lock tongue 503. A lock groove 504 is formed on the lock base 502. The lock tongue 503 is located in the lock groove 504. The lock link 501 can drive the lock tongue 503 to retract to the outside of the lock groove 504.

[0153] When unlocking the first battery pack, the top rod 14 presses against the unlocking position 505 of the lock link 501 and drives the lock link 501 to move, so that the lock tongue 503 retracts to the outside of the lock slot 504; the first positioning fork 13 forks the first battery pack, and the upper plate 11 drives the first battery pack to move, so that the lock shaft of the first battery pack moves out of the lock slot 504, thereby unlocking the first battery pack. When locking the first battery pack, the top rod 14 moves to a position where it does not contact the lock link 501, the first positioning fork 13 forks the first battery pack, and the upper plate 11 drives the first battery pack to move, so that the lock shaft of the first battery pack enters the lock slot 504 and is locked.

[0154] The first disassembly and assembly mechanism 1 also includes a second positioning mechanism. The second positioning mechanism in this embodiment is a second positioning fork 15. The second positioning fork 15 is fixed on the lower plate 12. The second positioning fork 15 can cooperate with the positioning block on the electric vehicle to make the position of the lower plate 12 relatively fixed with the electric vehicle when unlocking or locking the first battery pack.

[0155] like Figure 4 , Figure 6 to Figure 7 As shown, the battery exchange device also includes a fixed plate 5, and the second disassembly mechanism 2 is fixed on the surface of the fixed plate 5 relative to the lower plate 12. The fixed plate 5 can be flipped relative to the upper plate 11 to move the second disassembly mechanism 2 to a disassembly position or an avoidance position. Figure 6 As shown, the fixed plate 5 is flipped to the top of the upper plate 11, and the second disassembly and assembly mechanism 2 is located at the disassembly and assembly position. The second disassembly and assembly mechanism 2 is located above the fixed plate 5, and the second disassembly and assembly mechanism 2 can disassemble and assemble the battery pack having the second locking mechanism; as shown Figure 7As shown, the fixed plate 5 is flipped to be parallel to the upper plate 11, the second disassembly and assembly mechanism 2 is located in the avoidance position, and the second disassembly and assembly mechanism 2 is located below the fixed plate 5. The second disassembly and assembly mechanism 2 does not affect the action of the first disassembly and assembly mechanism 1 to disassemble and assemble the battery pack.

[0156] like Figure 8 As shown, the second disassembly and assembly mechanism 2 includes a rotating part 21 and a rotation control mechanism 22. The second locking mechanism is provided with a locking end cooperating with the rotating part 21. The rotating part 21 is used to rotate the locking end of the second locking mechanism for disassembly and assembly; the rotation control mechanism 22 is used to control the rotation of the rotating part 21 so that the rotating part 21 can rotate the locking end to enable the second locking mechanism to realize disassembly and assembly.

[0157] Among them, the rotation control mechanism 22 includes a motor 221 and a reducer 222, and the output of the motor 221 can be directly or indirectly input into the reducer 222. For example, the connecting shaft (not marked) provided in the motor 221 can extend into the coupling (not marked) in the reducer 222, thereby realizing the connection between the motor 221 and the reducer 222. The speed of the motor 221 is changed by the reducer 222, and then the reducer 222 directly or indirectly drives the rotating part 21 to tighten or loosen the locking end of the second locking mechanism, thereby realizing the removal or installation of the second battery pack. The bolt is a typical example of the locking end of the second locking mechanism. However, it can be understood that, in addition to the bolt, the rotating part 21 can be used to screw any component that requires a rotation operation; it is only necessary to design the rotating part 21 to match the shape of the locking end of the second locking mechanism.

[0158] The upper plate 11 is provided with a hidden groove, and the push rod 14 can be rotated into the hidden groove; when the push rod 14 is located in the hidden groove, the push rod 14 does not affect the action of the second disassembly and assembly mechanism 2 to disassemble and assemble the battery pack.

[0159] The first positioning fork 13 can also be foldably mounted on the upper plate 11 . When the first positioning fork 13 is folded from a vertical state to a horizontal state, the first positioning fork 13 does not affect the movement of the second disassembly and assembly mechanism 2 in disassembling and assembling the battery pack.

[0160] The second positioning fork 15 can also be foldably mounted on the lower plate 12 . When the second positioning fork 15 is folded from a vertical state to a horizontal state, the second positioning fork 15 does not affect the movement of the second disassembly and assembly mechanism 2 in disassembling and assembling the battery pack.

[0161] The selection of the hiding method of the first positioning fork 13, the second positioning fork 15 and the top rod 14 depends on the actual demand for the disassembly and assembly space required by the second disassembly and assembly mechanism 2. When the multifunctional battery exchange device has other disassembly and assembly mechanisms in addition to the second disassembly and assembly mechanism 2, the first positioning fork 13, the second positioning fork 15 and the top rod 14 can also be hidden in other ways to achieve the purpose of not affecting the disassembly and assembly of the battery pack by other disassembly and assembly mechanisms.

[0162] Example 4

[0163] The structure of the multifunctional battery exchange device of Example 4 is substantially the same as that of Example 3, except that:

[0164] like Fig. 9 As shown, the edge of the upper plate 11 forms a receiving space 111 for receiving the fixed plate 5, and a slide bar 112 is provided in the receiving space 111, and the fixed plate 5 is sleeved on the slide bar 112; the fixed plate 5 slides on the slide bar 112, so that the fixed plate 5 can slide back and forth relative to the upper plate 11; when the fixed plate 5 is extended to be away from the upper plate 11, the second disassembly and assembly mechanism 2 is located in the disassembly and assembly position, and the second disassembly and assembly mechanism 2 can disassemble and assemble the battery pack with the second locking mechanism; when the fixed plate 5 is retracted to be close to the upper plate 11, the second disassembly and assembly mechanism 2 is located in the avoidance position, and the second disassembly and assembly mechanism 2 does not affect the action of the first disassembly and assembly mechanism 1 to disassemble and assemble the battery pack.

[0165] Through the above structure, the position switching of the second disassembly and assembly mechanism 2 can also be achieved to meet the need of avoiding the action of the first disassembly and assembly mechanism 1 to disassemble and assemble the battery pack.

[0166] In addition to the avoidance mechanisms described in Embodiments 3 and 4, avoidance mechanisms may also be designed according to the actual disassembly and assembly position and avoidance position of the second disassembly and assembly mechanism 2. As long as the avoidance mechanism can achieve the function of moving the second disassembly and assembly mechanism 2 to the disassembly and assembly position or the avoidance position, it is within the scope of protection claimed by the present invention.

[0167] Example 5

[0168] The structure of the multifunctional battery exchange device of Example 5 is substantially the same as that of Example 3, except that:

[0169] like Fig.10 As shown, the battery exchange device includes a replacement tray 6, which is detachably mounted on the upper plate 11, and the second disassembly mechanism 2 is mounted on the replacement tray 6. When the second disassembly mechanism 2 is needed to disassemble and assemble the battery pack, the replacement tray 6 is mounted on the upper plate 11, and the battery pack with the second locking mechanism can be disassembled and assembled. When the second disassembly mechanism 2 is not needed to disassemble and assemble the battery pack, the replacement tray 6 is removed without affecting the action of the first disassembly mechanism 1 to disassemble and assemble the battery pack.

[0170] The first assembly and disassembly mechanism 1 further includes a docking mechanism 16, which is mounted on the upper plate 11, and the replacement tray 6 is mounted on the docking mechanism 16. The docking mechanism 16 further includes an electrical interface, which is used to be electrically connected to the electrical interface of the second assembly and disassembly mechanism 2. The docking mechanism 16 is used to fix the replacement tray 6, and at the same time, the electrical interface of the docking mechanism 16 is also electrically connected to the electrical interface of the second assembly and disassembly mechanism 2 to provide power to the second assembly and disassembly mechanism 2.

[0171] Example 6

[0172] The structure of the multifunctional battery exchange device of Example 6 is roughly the same as that of Example 3. This embodiment provides a specific structure of a foldable positioning mechanism. The foldable first positioning mechanism (first positioning fork 13) and second positioning mechanism (second positioning fork 15) involved in the other embodiments mentioned above can refer to the positioning mechanism in this embodiment.

[0173] like Figure 11-Figure 15 As shown, this embodiment provides a positioning mechanism structure that can be flipped and folded, so that the positioning mechanism can switch between a vertical state and a horizontal state, that is, the positioning mechanism can be folded from a vertical state to a horizontal state, or flipped from a horizontal state to a vertical state. When the positioning mechanism is in a vertical state, the positioning mechanism can normally position the battery pack; when the positioning mechanism is in a horizontal state, the positioning mechanism can not interfere with other positioning devices positioning the battery pack and does not interfere with other disassembly and assembly mechanisms disassembling and assembling the battery pack.

[0174] like Figure 11-Figure 15 As shown, the positioning mechanism includes a positioning mechanism body 61 and a flipping mechanism for folding the positioning mechanism body 61. The positioning mechanism body 61 is used to abut against the battery pack to achieve the positioning of the battery pack. The flipping mechanism is connected to the positioning mechanism body 61 and is used to drive the positioning mechanism body 61 to rotate so that the positioning mechanism body 61 switches between a vertical state and a horizontal state.

[0175] like Fig.13 , Fig.16 and Fig.17As shown, the flip mechanism includes a driving member 62 and a rotating shaft 63, wherein the driving member 62 is connected to the rotating shaft 63 for driving the rotating shaft 63 to rotate, and the rotating shaft 63 is connected to the positioning mechanism body 61 for driving the positioning mechanism body 61 to rotate, so as to switch the positioning mechanism body 61 between a vertical state and a horizontal state. The rotating shaft 63 and the positioning mechanism body 61 in this embodiment are fixedly connected by a connecting member, specifically, a rotating shaft connecting hole 611 with two ends penetrating therethrough is provided at the lower end of the positioning mechanism body 61, and the rotating shaft 63 is passed through the rotating shaft connecting hole 611. The flip mechanism also includes a connecting member connected between the rotating shaft 63 and the positioning mechanism. In this embodiment, the connecting member is a pin key 64. The rotating shaft 63 is provided with a first key groove 631 for placing part of the pin key 64. The corresponding position of the rotating shaft connecting hole 611 is provided with a second key groove 612 for placing another part of the pin key 64. The first key groove 631 cooperates with the second key groove 612 to limit the movement of the pin key 64 in all directions, so as to achieve the position fixation of the pin key 64 relative to the rotating shaft 63 and the positioning mechanism body 61. During the rotation of the rotating shaft 63, the pin key 64 fixed relatively thereto is driven to rotate synchronously, thereby driving the positioning mechanism body 61 connected to the pin key 64 to flip.

[0176] In other alternative embodiments, other connectors capable of achieving the above functions may be selected to fix the rotation shaft 63 and the positioning mechanism body 61, or the connection between the rotation shaft 63 and the positioning mechanism body 61 may be achieved in other forms, such as directly fixing the rotation shaft 63 and the positioning mechanism body 61, wherein the direct fixed connection includes one-piece molding or welding. In this embodiment, the pin key 64 is selected as the connector connecting the rotation shaft 63 and the positioning mechanism body 61, which has a simple structure, is easy to install, and can improve assembly efficiency. The rotation shaft 63 and the positioning mechanism body 61 are fixedly connected, so that the positions of the rotation shaft 63 and the positioning mechanism body 61 are relatively fixed, so as to ensure that the positioning mechanism body 61 can rotate synchronously with the rotation shaft 63, thereby improving the reliability of the positioning mechanism body 61 flipping.

[0177] The driving member 62 in this embodiment is a rotary motor, which can directly drive the rotating shaft 63 to rotate. In other alternative embodiments, the driving member 62 can also select other structures that can drive the rotating shaft 63 to rotate.

[0178] like Fig.13 As shown, the flip mechanism also includes at least one position detection device for detecting the position of the positioning mechanism body 61 and determining whether the positioning mechanism body 61 is flipped to a vertical state or a horizontal state, so as to ensure the reliability of the positioning mechanism body 61 being adjusted in place, thereby ensuring the accuracy of the positioning mechanism in positioning the battery pack. The number of position detection devices in this embodiment is 2, and in other alternative embodiments, the number of position detection devices may also be one or more.

[0179] Specifically, Fig.11 and Fig.14 As shown, the position detection device in this embodiment includes a vertical sensor 651 and a horizontal sensor 652. The vertical sensor 651 is used to detect whether the positioning mechanism body 61 is flipped to a vertical state, and the horizontal sensor 652 is used to detect whether the positioning mechanism body 61 is flipped to a horizontal state. The vertical sensor 651 and the horizontal sensor 652 in this embodiment are both photoelectric sensors, which are non-contact sensors. The positioning mechanism body 61 will not interfere with the vertical sensor 651 and the horizontal sensor 652 during the rotation process, thereby ensuring the reliability of the flipping and folding of the positioning mechanism body 61. Moreover, the photoelectric sensor has a simple structure and a short response time, and is simple and reliable to control. It can timely identify the position of the positioning mechanism body 61, thereby improving the reliability of the position adjustment of the positioning mechanism body 61. In other alternative embodiments, the vertical sensor 651 and the horizontal sensor 652 can select other position detection devices that can achieve the above functions, and the vertical sensor 651 and the horizontal sensor 652 can select the same or different structures.

[0180] Based on the specific structure of the above positioning mechanism, the folding process of the positioning mechanism is briefly described below:

[0181] like Fig.16 As shown, during the process of folding the positioning mechanism body 61 from a vertical state to a horizontal state, the driving member 62 drives the rotating shaft 63 to rotate, and the rotating shaft 63 drives the pin key 64 connected thereto to rotate synchronously, thereby driving the positioning mechanism body 61 that cooperates with the pin key 64 to fold. When the horizontal sensor 652 detects the positioning mechanism body 61, the driving member 62 stops driving the rotating shaft 63 to rotate.

[0182] like Fig.17 As shown, during the process of the positioning mechanism body 61 flipping from the horizontal state to the vertical state, the driving member 62 drives the rotating shaft 63 to rotate in the opposite direction, and the rotating shaft 63 drives the pin key 64 connected thereto to rotate synchronously, thereby driving the positioning mechanism body 61 that cooperates with the pin key 64 to flip, and when the vertical sensor 651 detects the positioning mechanism body 61, the driving member 62 stops driving the rotating shaft 63 to rotate.

[0183] Another example Fig.13As shown, the flip mechanism also includes a connecting seat 66, a sleeve 67, a bearing 68, a flip seat 69 and a fixed bracket 610. Along the axial direction of the rotating shaft 63, the driving member 62, the connecting seat 66 and the flip seat 69 are connected in sequence, and the rotating shaft 63 passes through the connecting seat 66 and the flip seat 69 to connect with the driving member 62. The connecting seat 66 and the flip seat 69 play the role of supporting the rotating shaft 63 to ensure that the rotating shaft 63 can rotate stably. The outer side of the rotating shaft 63 is sleeved with a sleeve 67, and the sleeve 67 is connected to the rotating shaft 63 by a bolt 620, which plays the role of protecting the rotating shaft 63 and reducing the wear of the rotating shaft 63. The rotating shaft 63 is fixed on the flip seat 69 by a bearing 68, and realizes rotation relative to the flip seat 69. The vertical sensor 651 and the horizontal sensor 652 are installed on the fixed bracket 610, and the fixed bracket 610 is fixed on the flip seat 69. The fixed bracket 610 plays the role of supporting the vertical sensor 651 and the horizontal sensor 652. The vertical sensor 651 and the horizontal sensor 652 remain stationary relative to the flip seat 69 to ensure the accuracy of position detection. The flip mechanism of this embodiment also includes a reducer, which is connected between the driving member 62 and the rotating shaft 63 to reduce the rotation speed transmitted from the driving member 62 to the rotating shaft 63, thereby improving the stability of the flipping of the positioning mechanism body 61.

[0184] In addition, the existing positioning mechanism is usually installed on the battery swapping equipment and moves synchronously with the battery swapping equipment, wherein the highest point of the positioning mechanism is usually also the highest point of the battery swapping equipment. During the disassembly and assembly of the battery pack, the battery swapping equipment needs to be moved to the bottom of the electric vehicle, so the chassis height of the electric vehicle will affect the movement of the battery swapping equipment. In the prior art, the chassis height of the electric vehicle is usually less than the height of the battery swapping equipment. Therefore, during the disassembly and assembly of the battery pack, the electric vehicle needs to be lifted before the battery swapping equipment can be moved to the bottom of the electric vehicle. Moreover, after the disassembly and assembly of the battery pack is completed, it is also necessary to wait for the battery swapping equipment to move out of the bottom of the electric vehicle before the electric vehicle can be lowered to prevent interference between the electric vehicle and the battery swapping equipment. The entire process takes a long time to swap batteries, and the battery swapping efficiency is low.

[0185] Since the highest point of the positioning mechanism is usually also the highest point of the battery swapping device, when the positioning mechanism is in a vertical state, the overall height of the battery swapping device is the highest, and when the positioning mechanism is in a horizontal state, the overall height of the battery swapping device is the lowest. Therefore, the positioning mechanism that can be flipped and folded provided in this embodiment can change the position of the highest point of the positioning mechanism by flipping and folding the positioning mechanism, that is, change the overall height of the battery swapping device, so that it is convenient for the battery swapping device to enter and exit the bottom of the electric vehicle. In other words, before the battery swapping device enters the bottom of the electric vehicle, the positioning mechanism can be kept in a horizontal state. At this time, the overall height of the battery swapping device is the lowest and can be lower than the height of the chassis of the electric vehicle, so that the battery swapping device can drive into the bottom of the electric vehicle even if the electric vehicle is not lifted. The lifting process of the electric vehicle and the process of flipping the positioning mechanism to a vertical state can be carried out simultaneously, and the lowering process of the electric vehicle and the process of folding the positioning mechanism to a horizontal state can also be carried out simultaneously, thereby shortening the battery swapping time and improving the battery swapping efficiency.

[0186] Specifically, the control method of the battery swapping device may include the following steps:

[0187] Step 1: Control the first positioning mechanism and the second positioning mechanism to flip to a horizontal state;

[0188] Step 2: Control the battery exchange equipment to move to the bottom of the electric car.

[0189] The first positioning mechanism and the second positioning mechanism can be flipped to a horizontal state before the vehicle enters. When the electric vehicle is not lifted, the battery exchange equipment can be directly moved to the bottom of the electric vehicle without waiting for the electric vehicle to be lifted, thereby shortening the battery exchange time and improving the battery exchange efficiency.

[0190] Among them, after step 2, it also includes: step 3, controlling the first positioning mechanism and the second positioning mechanism to flip to a vertical state and execute the corresponding battery removal process.

[0191] When the battery swap device is moved to the disassembly and assembly position at the bottom of the electric vehicle, the first positioning mechanism and the second positioning mechanism can be switched from a horizontal state to a vertical state to achieve the positioning of the battery pack. During this process, the electric vehicle can be lifted synchronously, which can prevent the first positioning mechanism and the second positioning mechanism from interfering with the bottom of the electric vehicle, and can also further shorten the battery swap time and improve the battery swap efficiency.

[0192] Before step 1, the method may further include: determining the vehicle information of the electric vehicle, and determining whether the position state of the first positioning mechanism or the second positioning mechanism needs to be flipped according to the chassis height and other related information in the vehicle information. Thus, whether step 1 needs to be performed is determined according to the chassis height of the electric vehicle. For electric vehicles with a higher chassis, step 1 may not be performed, thereby simplifying the battery replacement steps.

[0193] Secondly, there are usually multiple positioning mechanisms on a battery exchange device to ensure that each part of the battery pack is evenly stressed and to improve the stability of the battery pack positioning. In a preferred embodiment, each positioning mechanism can independently achieve flipping and folding, so that each positioning mechanism can be flexibly controlled without interfering with each other. In other alternative embodiments, multiple positioning mechanisms in a battery exchange device can also jointly control flipping and folding.

[0194] In addition, in the prior art, part of the positioning mechanism on the battery swapping device is arranged on the frame of the battery swapping device, and the other part is arranged on the battery tray of the battery swapping device. In order to realize that a battery swapping device can position battery packs of different sizes, it can only be achieved by replacing the battery trays with the positioning mechanism located at different positions. This method is relatively troublesome and costly. If the battery swapping device adopts the positioning mechanism of the present embodiment, multiple sets of positioning mechanisms can all be installed on the frame of the battery swapping device. For battery packs of different sizes, it is only necessary to select the corresponding positioning mechanism to be in a vertical state, and the other positioning mechanisms can be folded to a flipped state. Therefore, there is no need to replace the battery tray, and the cost is low. In another embodiment, the structure of the first positioning mechanism and the second positioning mechanism can also adopt a U-shaped structure different from that of the present embodiment, for example, it can be L-shaped, rod-shaped, etc., as long as it can realize the positioning function with the battery pack or the chassis of the electric vehicle.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
