In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0118] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0119] In addition, in the following embodiments, the first direction refers to the direction of the vehicle entering and exiting the battery swap platform, that is, the length direction of the vehicle body when the vehicle is parked on the battery swap platform. The second direction refers to the vertical direction of the first direction in the horizontal plane, that is, the width direction of the vehicle body when the vehicle is parked on the battery swap platform.

[0120] First refer to Figure 1 and Figure 2 , describe the battery swap platform of this application.

[0121] like Figure 1 and Figure 2 As shown, in order to solve the problem of poor wheelbase compatibility of the battery swapping platform of the charging and swapping station, the battery swapping platform of the present application includes a fixed frame 1, a first positioning device 21, a second positioning device 22, a first lifting mechanism 31, a second lifting mechanism 32 and a first wheelbase adjustment mechanism 41. The first positioning device 21 is arranged on one side of the fixed frame 1 along the first direction, and is used to position the front wheel or rear wheel of the vehicle to be battery swapped. The second positioning device 22 is arranged on the other side of the fixed frame 1 along the first direction, and is correspondingly used to position the rear wheel or front wheel of the vehicle to be battery swapped. The first lifting mechanism 31 is used to lift the first positioning device 21, the second lifting mechanism 32 is used to lift the second positioning device 22, the first wheelbase adjustment mechanism 41 is arranged between the first positioning device 21 and the first lifting mechanism 31, and the first wheelbase adjustment mechanism 41 is used to adjust the position of the first positioning device 21 relative to the second positioning device 22 in the first direction.

[0122] For example, during the battery swapping process, the vehicle parks and enters the battery swapping platform. After parking, the two front wheels of the vehicle are located on the first positioning device 21, and the two rear wheels are located on the second positioning device 22. Next, the first lifting mechanism 31 and the second lifting mechanism 32 act simultaneously to lift the vehicle to a certain height, and the battery swapping robot enters under the vehicle to complete the removal of the depleted battery and the subsequent installation of the fully charged battery. When the wheelbase of the battery swapping vehicle does not match the wheelbase range supported by the current first positioning device 21 and the second positioning device 22, the front wheels or rear wheels of the vehicle cannot be accurately positioned on the corresponding positioning device. At this time, before the vehicle is parked, the first wheelbase adjustment mechanism 41 is controlled to act to drive the first positioning device 21 to move along the first direction, thereby adjusting the distance between the first positioning device 21 and the second positioning device 22, so that after the vehicle is parked and enters the battery swapping platform, the two front wheels and the two rear wheels can be accurately parked on the first positioning device 21 and the second positioning device 22, respectively.

[0123] The battery swap platform of the present application can adjust the position of the first positioning device 21 in the first direction by setting the first wheelbase adjustment mechanism 41, thereby adjusting the distance between the first positioning device 21 and the second positioning device 22, improving the wheelbase compatibility of the battery swap platform, and making the battery swap platform suitable for positioning and battery swapping of more wheelbase models. The setting of the first lifting mechanism 31 and the second lifting mechanism 32 can be used to lift the first positioning device 21 and the second positioning device 22 to achieve lifting of the vehicle, which is conducive to forming a larger battery swap space at the bottom of the vehicle and facilitating battery swap operations.

Specifically, the first adjustment drive unit 411 includes a first adjustment motor 4111 and a first pulley transmission assembly 4112. The first adjustment transmission unit 412 is a first screw nut assembly. The first adjustment motor 4111 is transversely arranged on the lifting plate. The screw in the first screw nut assembly is transversely fixedly connected to the lifting plate and is located below the first adjustment motor 4111. The output end of the first adjustment motor 4111 is connected to the screw in the first screw nut assembly through the first pulley transmission assembly 4112. The nut in the first screw nut assembly is connected to one end of the first positioning device 21 through the first connecting portion 51.

The second wheelbase adjustment mechanism 42 includes a second adjustment drive unit and a second adjustment transmission unit, the second adjustment drive unit is arranged on the second lifting member and connected to the second adjustment transmission unit, the second adjustment transmission unit is arranged on the second lifting member and connected to one end of the second positioning device 22.

[0131] Return to see Figure 2 The first connection part 51 includes a first hanging plate 511, a first adapter seat 512 and a first hinge seat 513. The first hanging plate 511 is fixedly connected to the nut in the first lead screw nut assembly. Two first adapter seats 512 are provided. The two first adapter seats 512 are fixedly connected to the first hanging plate 511. The first hinge seat 513 is fixedly connected to one end of the first installation frame 211 and is hinged to the two first adapter seats 512. Similarly, the second connection part 52 includes a second hanging plate, a second adapter seat and a second hinge seat.

The second hinge seat is fixedly connected to one end of the second installation frame 221 and is hinged to the second adapter seat.

[0132] See also Figure 5, a first guide mechanism 61 is also provided between the first connecting portion 51 and the first lifting member 312. Preferably, the first guide mechanism 61 is a slide rail and slider assembly, and two groups of slide rail and slider assemblies are provided, and the two groups of slide rail and slider assemblies are respectively arranged on the upper and lower sides of the first screw nut assembly. Each slide rail and slider assembly includes a slide rail and two sliders, and the slide rail is laterally fixedly connected to the lifting plate.

A second guide mechanism is also provided between the second connecting portion 52 and the second lifting member. The second guide mechanism is preferably also a slide rail and slider assembly, and its setting method is similar to that of the first guide mechanism 61, and it will not be repeated.

[0133] In this way, during the battery replacement process, the first lifting mechanism 31 drives the first lifting member 312 to move up and down through the first lifting drive unit 311, and the second lifting mechanism 32 drives the second lifting member to move up and down through the second lifting drive unit.

When it is necessary to adjust the position of the first positioning device 21 in the first direction, the first adjustment motor 4111 is operated, and its driving force is transmitted to the first screw nut assembly through the first pulley transmission assembly 4112. The screw in the first screw nut assembly rotates, driving the nut in the first screw nut assembly to move horizontally, so that the first hanging plate 511 connected to the nut drives the first positioning device 21 to move along the first direction, and the first connecting rib plate 2112 moves along the first insertion slot 11.

[0134] By setting the first wheelbase adjustment mechanism 41 and the second wheelbase adjustment mechanism 42 to adjust the positions of the first positioning device 21 and the second positioning device 22 in the first direction respectively, a wider range of wheelbase compatibility can be achieved. By setting two first lifting mechanisms 31 and two second lifting mechanisms 32, it is beneficial to improve the stability of the lifting process. Each first lifting mechanism 31 is connected to one end of the first positioning device 21 through a first wheelbase adjustment mechanism 41, and each second lifting mechanism 32 is connected to one end of the second positioning device 22 through a second wheelbase adjustment mechanism 42, which is beneficial to improve the smoothness of the wheelbase adjustment process. The first guide mechanism 61 and the second guide mechanism are provided to improve the smoothness of the wheelbase adjustment process.

[0135] See also Figure 2 , Figure 5 and Figure 6 , the first limiting mechanism 71 is arranged below the first connection part 51, and the first limiting mechanism 71 is arranged to limit the movement of the first connection part 51 along the first direction. Specifically, the first limiting mechanism 71 includes a first limiting driving part 711, a first limiting member 712, a first limiting support 713, a first limiting guide block 714, a first limiting push block 715 and a first pin shaft 716. The first limiting support 713 is fixedly connected in the charging and swapping station, and the first limiting guide block 714 is fixedly connected to the first limiting support 713. The first limiting guide block 714 is provided with a first pulling hole 7141 penetrating along the first direction, a first lifting hole 7142 penetrating along the vertical direction, and two first long strip holes 7143 penetrating along the second direction, wherein the length of the first lifting hole 7142 along the first direction is equal to the length of the first limiting member 712 along the first direction. The first limit push block 715 is movably arranged in the first pull-out hole 7141, and one end of the first limit push block 715 is connected to the first limit driving part 711. The first limit driving part 711 is preferably an electric cylinder. When the electric cylinder is actuated, the first limit push block 715 is driven to move along the first pull-out hole 7141. The first limit push block 715 is provided with a first receiving hole 7151 penetrating in the vertical direction, and two first pin holes 7152 penetrating in the second direction. The length of the first receiving hole 7151 in the first direction is greater than the length of the first limit member 712 in the first direction. The first limit member 712 is a limit plug plate, which is inserted into the first receiving hole 7151, and the upper part of the first limit member 712 extends from the top of the first lifting hole 7142, and the lower part of the first limit member 712 extends from the bottom of the first lifting hole 7142. The first limit member 712 can move up and down along the first lifting hole 7142. The first stopper 712 is provided with two first adjustment holes 7121 penetrating along the second direction, and the two ends of the first adjustment hole 7121 have different heights. In the present application, the first adjustment hole 7121 includes two horizontal sections and an inclined section located between the two horizontal sections, and the heights of the two horizontal sections are different. An upper tooth portion 7122 is formed at the top of the first stopper 712, and a lower tooth portion 5111 is formed at the bottom of the first hanging plate 511. The upper tooth portion 7122 matches the lower tooth portion 5111, and preferably, the length of the upper tooth portion 7122 is greater than the length of the lower tooth portion 5111. Two first pin shafts 716 are provided, and each first pin shaft 716 passes through the first long hole 7143, the first pin hole 7152 and the first adjustment hole 7121 in sequence, so as to assemble the first stopper 712, the first stopper push block 715 and the first stopper guide block 714 together.

[0136] In this way, during the telescopic movement of the electric cylinder, the first limit push block 715 makes a pulling / pulling movement in the first pulling hole 7141 of the first limit guide block 714. During the movement, the first limit push block 715 drives the first pin shaft 716 to move along the first long hole 7143 on the first limit guide block 714. During the movement, the first pin shaft 716 moves from one end to the other end of the first adjustment hole 7121 on the first limit member 712. Since the length of the first limit member 712 in the first direction is equal to the length of the first lifting hole 7142 in the first direction, the movement of the first limit member 712 along the first direction is restricted. Since the heights of the two ends of the first adjustment hole 7121 are different, the first limit member 712 finally makes an ascending / descending movement along the first lifting hole 7142. Among them, when the first limiting member 712 rises, the upper tooth portion 7122 of the first limiting member 712 engages with the lower tooth portion 5111 of the first hanging plate 511, and the movement of the first hanging plate 511 along the first direction is restricted; when the first limiting member 712 descends, the upper tooth portion 7122 of the first limiting member 712 disengages from the lower tooth portion 5111 of the first hanging plate 511, and the movement restriction of the first hanging plate 511 along the first direction is released.

[0137] By setting the first limit mechanism 71, the impact on the first wheelbase adjustment mechanism 41 when the vehicle goes up and down the battery swapping platform can be prevented, thereby protecting the first wheelbase adjustment mechanism 41. By setting the first limit member 712 to move up and down, the first limit member 712 can be prevented from interfering with the adjustment when the position of the first positioning device 21 is adjusted, and by setting the upper tooth portion 7122 to mesh with the lower tooth portion 5111, the first limit member 712 can continue to effectively mesh with the first connecting portion 51 after the position of the first positioning device 21 is adjusted.

[0138] It should be noted that the specific composition of the second limiting mechanism 72 is similar to that of the first limiting mechanism 71 , and only a brief description is given below.

[0139] The second limiting mechanism 72 is arranged below the second connecting portion 52, and the second limiting mechanism 72 is arranged to limit the second connecting portion 52 from moving in the first direction. Specifically, the second limiting mechanism 72 includes a second limiting driving portion, a second limiting member, a second limiting support, a second limiting guide block, a second limiting push block and a second pin shaft. The second limiting support is fixedly connected in the charging and swapping station, and the second limiting guide block is fixedly connected to the second limiting support. The second limiting guide block is provided with a second pulling hole extending in the first direction, a second lifting hole extending in the vertical direction and a second long strip hole extending in the second direction, and the length of the second lifting hole in the first direction is equal to the length of the second limiting member in the first direction. The second limiting push block is movably arranged in the second pulling hole, and one end of the second limiting push block is connected to the second limiting driving portion. The second limiting driving portion is preferably an electric cylinder, which drives the second limiting push block to move along the second pulling hole when the electric cylinder is actuated. The second limit push block is provided with a second receiving hole penetrating in the vertical direction and a second pin hole penetrating in the second direction, and the length of the second receiving hole in the first direction is greater than the length of the second limit piece in the first direction. The second limit piece is a limit plug plate, which is inserted in the second receiving hole, and the upper part of the second limit piece extends from the second lifting hole, and the lower part of the second limit piece extends from the bottom of the second lifting hole, and the second limit piece can be lifted and moved along the second lifting hole. The second limit piece is provided with two second adjustment holes penetrating in the second direction, and the two ends of the second adjustment holes have different heights. The top of the second limit piece is formed with an upper tooth portion, and the bottom of the second hanging plate is formed with a lower tooth portion, and the upper tooth portion and the lower tooth portion match each other. Preferably, the length of the upper tooth portion is greater than the length of the lower tooth portion. Two second pin shafts are provided, and each second pin shaft passes through the second long hole, the second pin hole and the second adjustment hole in sequence, and the second limit piece, the second limit push block and the second limit guide block are assembled together.

[0140] In this way, when the second limit driving part is activated, it can drive the second limit member to move up and down. When the second limit member rises, the upper tooth portion engages with the lower tooth portion. When the second limit member descends, the upper tooth portion and the lower tooth portion disengage from each other.

[0141] By setting the second limit mechanism 72, the impact on the second wheelbase adjustment mechanism 42 when the vehicle goes up and down the battery swapping platform can be prevented, thereby protecting the second wheelbase adjustment mechanism 42. By setting the second limit member to move up and down, the second limit member can be prevented from interfering with the adjustment when the position of the second positioning device 22 is adjusted, and by setting the upper tooth portion to mesh with the lower tooth portion, the second limit member can continue to effectively mesh with the second connecting portion 52 after the position of the second positioning device 22 is adjusted.

[0142] See also Figure 1 , Figure 3 and Figure 4, the follower platform 8 is arranged on one side of the fixed frame 1 along the second direction, one end of the follower platform 8 is connected to the first mounting frame 211, and the other end can be relatively slidably connected to the second positioning device 22. Specifically, the follower platform 8 is arranged on the side of the main cab when the vehicle is parked and enters the battery exchange platform, and a mobile support 81 is hingedly arranged on the lower side of the follower platform 8. A fixed support 223 is fixedly arranged on the side wall of the second mounting frame 221 of the second positioning device 22, and the mobile support 81 is slidably connected to the fixed support 223. Among them, a third guide mechanism 63 is arranged between the mobile support 81 and the fixed support 223. The third guide mechanism 63 is preferably a slide rail slider assembly, the slide rail is arranged on the mobile support 81, the slider is fixedly connected to the fixed support 223, and the mobile support 81 and the fixed support 223 are slidably connected through the slide rail slider assembly.

[0143] By providing the follower platform 8, after the vehicle is lifted, the follower platform 8 can be used as a step for getting on and off the vehicle, which is convenient for people in the vehicle to get on and off the vehicle and avoid stepping on empty space when getting off the vehicle. One end of the follower platform 8 is connected to the first installation frame 211, and the other end can be relatively slidably connected to the second installation frame 221, so that the relative position of the follower pedal remains unchanged when the position of the first positioning device 21 is adjusted. The movable support 81 is slidably connected to the fixed support 223, which can improve the bearing stability of the follower platform 8 after moving. By providing the third guide mechanism 63, the movement stability between the movable support 81 and the fixed support 223 can be improved.

[0144] It should be noted that the above preferred implementations are only used to illustrate the principles of the present application and are not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may adjust the above settings so that the present application can be applied to more specific application scenarios.

[0145] For example, in an alternative embodiment, although the above embodiment is described in combination with the example that two first lifting mechanisms 31 and two second lifting mechanisms 32 are provided, this is only a preferred embodiment. In other embodiments, the structures of the first lifting mechanism 31 and the second lifting mechanism 32 can also be adjusted. For example, the first lifting mechanism 31 and / or the second lifting mechanism 32 are configured as a lifting drive unit to simultaneously drive two lifting members to lift the positioning device, such as by driving two driving chains simultaneously by a motor to drive the two lifting members to rise and fall. Or the first lifting mechanism 31 can also be configured as other forms, such as a scissor-fork type lifting mechanism.

[0146] For another example, in another replaceable embodiment, although each first lifting mechanism 31 in the above embodiment is connected to one end of the first positioning device 21 through a first wheelbase adjustment mechanism 41, and each second lifting mechanism 32 is connected to one end of the second positioning device 22 through a second wheelbase adjustment mechanism 42, this arrangement is only exemplary. In other embodiments, those skilled in the art can selectively adjust the number of the first wheelbase adjustment mechanism 41 and the second wheelbase adjustment mechanism 42. For example, only one of the two first lifting mechanisms 31 is connected to one end of the first positioning device 21 through the first adjustment mechanism, and the other first lifting mechanism 31 is connected to the first positioning device 21 through the slide rail slider to achieve follow-up. The second lifting mechanism 32 is similar and will not be described in detail.

[0147] For example, in another alternative embodiment, although the above embodiment is introduced in conjunction with the example of providing a second wheelbase adjustment mechanism 42, the provision of the second wheelbase adjustment mechanism 42 is not necessary, and those skilled in the art can make provision based on specific needs. For example, in some embodiments, the provision of the second wheelbase adjustment mechanism 42 can also be omitted.

[0148] For another example, in another replaceable embodiment, the specific structural form of the first lifting mechanism 31 is not unique, and those skilled in the art can adjust it as long as the first lifting mechanism 31 can achieve the lifting of the first positioning device 21. For example, in addition to the hydraulic cylinder, the first lifting drive unit 311 can also use an electric cylinder or a pneumatic cylinder. Alternatively, the first lifting drive unit 311 can also be replaced by a combination of a drive motor and a lifting chain, or a combination of a drive motor and a screw nut assembly. For another example, in addition to the lifting plate, the first lifting member 312 can also be a block or other irregular shape. The replaceable manner of the second lifting mechanism 32 is similar to that of the first lifting mechanism 31, and will not be repeated.

[0149] For another example, in another replaceable embodiment, the specific form of the first wheelbase adjustment mechanism 41 is not fixed, and the above embodiment is only a preferred method, and those skilled in the art can make adjustments based on specific needs. For example, the first adjustment motor 4111 is directly connected to the screw in the first screw nut assembly, and the first pulley transmission assembly 4112 is omitted; for another example, the first wheelbase adjustment mechanism 41 can also adopt a combination of a motor and a gear rack assembly, or a combination of a motor and a gear chain, etc., to achieve wheelbase adjustment through a rack or chain. The replaceable method of the second wheelbase adjustment mechanism 42 is similar to that of the first wheelbase adjustment mechanism 41, and will not be repeated.

[0150] For another example, in another replaceable embodiment, although the first connecting portion 51 is provided in the above embodiment, the provision of the first connecting portion 51 is not necessary, and those skilled in the art may directly connect the nut in the first screw nut assembly to the first positioning device 21. In addition, the specific composition of the first connecting portion 51 is not unique, and those skilled in the art may adjust it, such as only one first adapter seat 512 may be provided, or any one of the first hinge seat 513, the first hanging plate 511, and the first adapter seat 512 may be omitted. The replaceable manner of the second connecting portion 52 is similar to this, and will not be described in detail.

[0151] For another example, in another replaceable embodiment, the first guide mechanism 61, the second guide mechanism and the third guide mechanism 63 are not required, and those skilled in the art can choose whether to set them based on the specific scenario, as well as the specific setting form of the above three guide mechanisms. For example, none of the above three guide mechanisms can be set, or only some of them can be set. In addition to the slide rail slider, the guide mechanism can also be replaced by a slide groove slider, a slider slider, etc. When setting the slide rail slider assembly, if possible, the setting position between the slide rail and the slider can also be swapped.

[0152] For example, in another replaceable embodiment, the setting of the first limit mechanism 71 is only preferred, and those skilled in the art can choose whether to set the first limit mechanism 71 based on the specific application scenario. Of course, if the first limit mechanism 71 is omitted, it may cause an impact on the platform structure when the vehicle goes up and down the battery exchange platform. Furthermore, the specific setting form of the first limit mechanism 71 is not unique, and those skilled in the art can also adjust it. For example, the first limit mechanism 71 may only include a first limit drive unit 711 and a first limit member 712, such as the first limit drive unit 711 adopts a combination of a drive motor and a lead screw nut assembly, and the first limit member 712 adopts a limit plate with an upper tooth portion, and the limit plate is connected to the nut in the lead screw nut assembly. Or the first limit drive unit 711 is replaced by a motor and a gear chain, a motor and a gear rack, etc. In short, as long as the lifting and lowering movement of the first limit member 712 can be achieved, it can be used. For another example, the first limiting mechanism 71 can also be set to other limiting forms, such as opening a plurality of positioning holes along the second direction on the first hanging plate 511, and setting a telescopic rod driving mechanism, when it is necessary to limit the movement of the first hanging plate 511, the telescopic rod is driven to extend and insert into a positioning hole. Similarly, those skilled in the art can also adjust the second limiting mechanism 72.

[0153] For another example, in another replaceable embodiment, although the above embodiment is described in combination with the first positioning device 21 including the first mounting frame 211 and the first roller group 212, the specific structure of the first positioning device 21 is not fixed, and those skilled in the art can adjust it according to the specific application scenario. For example, the first mounting frame 211 of the first positioning device 21 can be adjusted to other shapes; for another example, the first roller group 212 can be interchangeable with the I-type roller group in addition to the V-type roller group. Similarly, those skilled in the art can also make the above adjustments to the specific composition of the second positioning device 22.

[0154] For example, in another alternative embodiment, the first flange 2111 and the first connecting rib 2112 on the first installation frame 211 are not necessarily provided. When the above structure is provided, the stability of the first installation frame 211 during movement can be improved. Of course, those skilled in the art can also choose to omit the provision of the structure. Accordingly, the first insertion slot 11 on the fixed frame 1 can also be omitted. Similarly, the second installation frame 221 and the second insertion slot 12 can also be adjusted in the above manner.

[0155] For another example, although the above-mentioned embodiment is introduced in conjunction with the battery exchange platform including the follower platform 8, the setting of the follower platform 8 is only a preferred solution. In other embodiments, the follower platform 8 can also be omitted. At this time, the area of ​​the fixed frame 1 can be expanded to fill the position of the follower platform 8. For another example, in the case of setting the follower platform 8, as long as it is ensured that the follower platform 8 can be slidably set relative to the second positioning device 22, the specific slidable setting method can be adjusted by those skilled in the art. For example, only a movable support 81 can be set under the follower platform 8, and a roller is set under the movable support 81 to achieve sliding relative to the second positioning device 22. Alternatively, the follower platform 8 and the fixed platform do not contact each other, but are arranged in a manner of being plugged in at intervals from each other.

[0156] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0157] The present application also provides a charging and swapping station, which includes the battery swapping platform of the above embodiment.

[0158] The charging and swapping station of the present application, by setting a first wheelbase adjustment mechanism 41 on the battery swapping platform, can use the first wheelbase adjustment mechanism 41 and the second wheelbase adjustment mechanism 42 to adjust the positions of the first positioning device 21 and the second positioning device 22 in the first direction respectively, thereby improving the wheelbase compatibility of the battery swapping platform, and making the battery swapping platform suitable for positioning and battery swapping of more wheelbase models. The setting of the first lifting mechanism 31 and the second lifting mechanism 32 can be used to lift the first positioning device 21 and the second positioning device 22 to achieve lifting of the vehicle, which is conducive to forming a larger battery swapping space at the bottom of the vehicle and facilitating battery swapping operations.

[0159] The following is an introduction to a possible battery replacement process of the charging and swapping station of the present application.

[0160] In a possible implementation, the wheelbase of the next vehicle to be replaced is first obtained, and then the first limiting mechanism 71 and the second limiting mechanism 72 are controlled to operate, so that the first limiting member 712 and the second limiting member are lowered, and the movement restriction of the first hanging plate 511 and the second hanging plate is released. Then the first wheelbase adjustment mechanism 41 and / or the second wheelbase adjustment mechanism 42 are controlled to operate, and the distance between the first positioning device 21 and the second positioning device 22 is adjusted, so that the distance between the adjusted first positioning device 21 and the second positioning device 22 matches the wheelbase of the vehicle to be replaced. After the adjustment is completed, the first limiting mechanism 71 and the second limiting mechanism 72 are controlled to operate again, so that the first limiting member 712 and the second limiting member are raised, and the movement of the first hanging plate 511 and the second hanging plate is restricted respectively. After that, the vehicle to be replaced is parked and enters the replacement platform, and the front wheels of the vehicle to be replaced are stuck in the V-shaped roller group of the first positioning device 21, and the rear wheels are supported on the I-shaped roller group for positioning. After the positioning is completed, the normal replacement process is carried out.
