Description

Technical Field

[0001] The present invention relates to the technical field of vehicle battery replacement, and in particular to a battery replacement platform. Background Art

[0002] With the rapid development of science and technology, new energy vehicle related technologies are also constantly updated and iterated at a faster speed. New energy vehicles are showing an explosive growth trend with advantages such as low cost, stable driving, fuel saving and reduced exhaust emissions. With the emergence of more and more new energy vehicles, realizing the rapid replenishment of battery power of new energy vehicles will be a difficult problem faced by the new energy vehicle industry. At present, the battery replenishment methods for new energy vehicles mainly include charging with charging piles and battery replacement mode. Among them, the charging efficiency of charging with charging piles is low, and it takes up to several hours to fully charge the battery; moreover, the number of charging piles is limited due to the large area occupied by the charging piles; the battery replacement mode refers to the centralized storage, centralized charging and unified distribution of a large number of batteries through centralized charging stations, and the battery replacement service for electric vehicles in the battery distribution station. Therefore, the use of battery replacement mode to replenish the battery power can solve the problem of long charging time. There are three main battery replacement methods in the battery replacement mode: chassis battery replacement, front cabin / tail battery replacement and side panel battery replacement.

[0003] In the chassis battery replacement method, one is to lift the vehicle with a lift, and the battery replacement vehicle enters the bottom of the vehicle and replaces the battery of the vehicle; the driver is in the vehicle during the entire battery replacement process. Since the vehicle needs to be repeatedly lifted during the removal and installation of the battery to cooperate with the battery replacement vehicle to perform the battery replacement operation, the user experience is poor. In addition, there is another way to set the battery replacement vehicle below the ground, and the battery replacement vehicle is parked above the battery replacement vehicle for battery replacement; at this time, since the battery replacement vehicle needs to be lifted and passed through the battery replacement opening set on the ground to contact the bottom of the vehicle for battery replacement, the design of the battery replacement opening on the ground is easy to cause inconvenience in driving the vehicle, there are safety hazards, and it is also easy for debris to enter the interior, such as garbage or other debris, resulting in the battery replacement function being affected and the safety is low. . Summary of the invention

[0004] This application provides a battery swap platform to solve the above technical problems. The existing vehicles are repeatedly lifted during the entire battery swap process, and the driver is in the vehicle throughout the process, resulting in a poor user experience; the design of the battery swap opening easily allows garbage and other debris to enter, resulting in the battery swap function being affected; the battery swap opening on the ground causes inconvenience in driving the vehicle and poses a safety hazard.

[0005] The present application provides a battery swap platform, wherein a shuttle channel for the movement of a battery swap vehicle is arranged at the bottom of the battery swap platform, and a battery swap port is opened on the battery swap platform for the battery swap vehicle to be lifted and moved for battery swap operations. The battery swap port has a protective door and a driving device, and the driving device drives the protective door to move to open or close the battery swap port.

[0006] Through the above-mentioned arrangement, a battery swap port is provided on the battery swap platform for the battery swap vehicle to perform battery swap operations; the battery swap vehicle can be located at the bottom of the vehicle to perform battery swap operations on the vehicle battery through the battery swap port, and the vehicle does not need to be lifted by a lifting mechanism, thereby improving the user experience; when the vehicle is parked in place, the protective door opens and the battery swap port is in an open state, and the electric vehicle can contact the bottom of the battery swap vehicle through the battery swap port and disassemble and replace the battery of the battery swap vehicle at the bottom of the battery swap vehicle; when the battery swap operation is completed, the protective door is closed to close the battery swap port; by setting a movable protective door and closing it when the battery swap operation is not required, the battery swap port can be protected, effectively preventing garbage and other debris from falling into the battery swap port and affecting the battery swap function; on the other hand, it can effectively avoid the inconvenience of vehicle driving caused by the design of the battery swap opening on the battery swap platform, avoid safety hazards, and enhance safety.

[0007] As a preferred embodiment, the protective door has a folding portion, and the folding portion is connected to a connecting device; the driving device drives the folding portion to extend or fold via the connecting device.

[0008] In this solution, the protective door is provided with a folding portion with accordion folds, so that the folding portion can be folded and stored from one side to the other when the protective door is opened. All of it can be stored on one side and can even be completely hidden in the wall of the battery exchange platform, thereby reducing the space occupied by the protective door and making the space look more open. The layered contraction folding method is more flexible and changeable, which will also increase the user experience. When the protective door needs to be closed, the folding portion gradually extends layer by layer from the contracted side, like a flowing wave line, which increases the visual beauty and user experience.

[0009] As a preferred embodiment, the connecting device includes a connecting bracket and a plurality of connecting blocks respectively connected to the folding parts; the connecting bracket is connected to the driving device; and the connecting block is movably connected to the battery exchange platform.

[0010] In this solution, the driving device is connected to the protective door through a connecting bracket, and the driving device drives the protective door to unfold or fold toward one side in sequence through the connecting bracket; the connecting block is connected to the bottom of the protective door to support the protective door; the connecting block is movably connected to the power exchange platform to guide the protective door, so that the protective door can translate along the power exchange platform to further realize the extension or folding movement of the protective door.

[0011] As a preferred embodiment, the battery exchange platform is provided with a track protruding toward the folding portion; or, the battery exchange platform is provided with a track protruding upward, and the connecting block is movably connected to the track.

[0012] In this solution, a track protruding toward the folding part is provided on the inner side of the power exchange platform along the moving direction of the protective door, so that the horizontal side of the folding part of the protective door can be movably connected to the power exchange platform. At this time, the connecting block is connected to the side of the protective door, and is movably connected to the track protruding toward the folding part of the power exchange platform through the connecting block, so that the protective door is supported in the horizontal direction, thereby protecting the protective door from sliding smoothly in the horizontal direction, and does not cause uneven force on both sides of the protective door, resulting in one side of the protective door being squeezed, causing the protective door to be skewed, and causing jamming when extending or folding in the horizontal direction. ; Alternatively, a track protruding upward is provided in the battery exchange platform, and a connecting block is connected to the bottom of the protective door, so that the protective door can be moved and connected to the upward track of the battery exchange platform through the connecting block at the bottom, ensuring that the protective door is subjected to equal support force in the vertical plane, so that the protective door is not prone to partial collapse in the vertical plane, thereby avoiding resistance when the driving device drives the protective door to move horizontally; whether supporting the horizontal side of the protective door or supporting the bottom of the protective door, the protective door can be protected, ensuring that the protective door opens or closes more smoothly, thereby improving the battery exchange efficiency.

[0013] As a preferred embodiment, relatively distributed grooves are provided in the battery exchange platform, and rollers are sleeved on the connecting blocks, and the rollers move along the grooves.

[0014] In this solution, a groove is provided inside the battery swap platform, and the connecting block is connected to a roller for movably connecting to the groove. When the protective door is extended or folded, the roller rolls in the groove to drive the protective door to move along the groove of the battery swap platform. The groove is embedded in the battery swap platform and will not protrude from the surface of the battery swap platform, thereby reducing the space occupied by the battery swap platform, and can realize an embedded connection between the protective door and the battery swap platform, thereby reducing the distance between the protective door and the battery swap platform, reducing dust intrusion, and being more conducive to cleaning. Moreover, the hidden design makes the appearance more beautiful and increases the user experience.

[0015] As a preferred embodiment, the protective door includes a first protective door and a second protective door; the first protective door and the second protective door are respectively connected to the connecting device;

[0016] The connecting device includes a rotating shaft and a plurality of support rods; the rotating shaft is rotatably connected to the battery exchange platform at both ends along the axial direction, and the driving device is connected to the rotating shaft through a rotating connecting piece; the first end of the support rod is connected to the rotating shaft, and the second end of the support rod is hingedly connected to the protective door, and the protective door can rotate relative to the battery exchange platform under the rotation of the rotating shaft to open or close the battery exchange port.

[0017] In this solution, the protective door includes a first protective door and a second protective door symmetrically arranged on both sides of the power exchange port. The first protective door and the second protective door are respectively connected to the connecting device, so that the first protective door and the second protective door can be opened or closed to both sides respectively. The simultaneous movement of the two protective doors shortens the waiting time for closing or opening compared to a single protective door, and improves the efficiency of opening or closing the power exchange port; by rotating the rotating shaft located at the bottom of the power exchange platform and arranged along the width direction of the power exchange platform, the support rod is driven to interact with the protective door to realize the rapid opening or closing of the protective door. It only needs to start the rotating shaft to rotate in the forward or reverse direction to realize the rapid opening or closing of the protective door, thereby improving the power exchange efficiency.

[0018] As a preferred embodiment, the first protective door and the second protective door are arranged along the width direction of the battery exchange platform; or, the first protective door and the second protective door are arranged along the length direction of the battery exchange platform.

[0019] In this solution, the first protective door and the second protective door can be set along the length direction of the battery exchange platform, which can increase the space for arranging the driving device and the connecting device; the first protective door and the second protective door can also be set along the width direction of the battery exchange platform to reduce the moving distance of the protective door and increase the battery exchange efficiency.

[0020] As a preferred embodiment, it also includes a pull rod, a first end of the pull rod is hingedly connected to the protective door, and a second end of the pull rod is hingedly connected to the power exchange platform.

[0021] In this solution, the pull rod is arranged between the protective door and the battery exchange platform to support the protective door above the battery exchange platform to prevent the protective door from being partially tilted during the movement relative to the battery exchange platform, causing failure of the protective door when opening or closing; the setting of the pull rod can limit the opening angle and position of the protective door to avoid the protective door from being unable to close due to excessive rotation angle; moreover, the pull rod is hingedly connected to the protective door and the battery exchange platform, and the protective door, support rod and pull rod cooperate to form a four-bar linkage mechanism to realize parallel movement of the protective door relative to the battery exchange platform. After the movement, the protective door remains parallel to the battery exchange platform, and the protective door has an outward swing door structure, which increases the safety and stability of the protective door.

[0022] As a preferred embodiment, the connecting device includes a connecting plate connected to the battery exchange platform and a movable component connected to the protective door; the movable component is movably connected to the connecting plate, and the protective door can be translated along the connecting plate through the movable component under the driving action of the driving device to open or close the battery exchange port.

[0023] In this solution, the connecting plate is connected to the power exchange platform below the protective door, which plays an effective supporting role for the protective door, preventing the protective door from collapsing in the horizontal plane and being unable to operate stably; the connecting plate serves as a guide for the protective door and has the function of guiding the moving position of the protective door. The connecting plate can ensure the moving path of the protective door, so that the protective door can move horizontally according to the predetermined moving path to achieve rapid opening or closing of the protective door, thereby ensuring the safety and convenience of the smooth operation of the protective door and increasing the power exchange efficiency.

[0024] As a preferred embodiment, a guide track is opened in the extension direction of the connecting plate; the moving assembly includes a first connecting member, a second connecting member and a guide roller; one end of the first connecting member and the second connecting member are respectively connected to the protective door, and the other end of the first connecting member and the second connecting member are rotatably connected to the guide roller, and the guide roller is rollingly connected to the guide track.

[0025] In this solution, a guide track for guiding the movement direction of the protective door is provided inside the connecting plate; the moving assembly connected to the bottom of the protective door is movably connected to the guide track, so that the protective door is driven to reciprocate along the guide track of the connecting plate by the moving assembly, thereby realizing the opening and closing of the protective door. The guide track serves as the moving path of the protective door to prevent the protective door from being offset during movement and causing the protective door to be unable to be opened and closed smoothly; the first connecting member and the second connecting member are fixedly connected to the bottom of the protective door to further provide a stable support force for the protective door, the guide roller is rotatably connected between the first connecting member and the second connecting member, and the guide roller is rollingly connected in the guide track, so that the protective door can run smoothly along the guide track, thereby improving the battery replacement efficiency.

[0026] As a preferred embodiment, the closed end of the guide rail is provided with an upwardly curved arc transition section, so that the protective door rises along the arc transition section of the guide rail to be flush with the top surface of the battery exchange platform.

[0027] In this solution, in order to enable the first protective door and the second protective door to close in the middle when running along the guide track, the guide track needs to extend to the middle of the battery exchange platform, and one end extending to the middle of the battery exchange platform serves as the closed end of the guide track; in order to enable the first protective door and the second protective door on both sides to achieve the top surface flush with the top surface of the battery exchange platform under the guiding action of the closed end, the closed end of the guide track is set to have an upward curved arc transition section. When the first protective door and the second protective door on both sides move relative to each other for closing, the guide roller at the bottom moves upward along the arc transition section, further pushing the first protective door and the second protective door to move upward, and finally achieving the top surface of the first protective door and the second protective door flush with the top surface of the battery exchange platform.

[0028] As a preferred embodiment, a guide rail is provided on the inner side of the battery exchange platform, and a roller is rotatably connected to the side of the protective door facing the guide rail through a positioning member, and the roller rolls along the guide rail.

[0029] In this solution, a guide rail is arranged on the battery exchange platform, and the protective door is provided with rollers which are rollingly connected to the guide rail, so as to further increase the supporting force of the protective door; in addition, the protective door can move along a predetermined route under the guidance of the guide rail, so as to prevent the protective door from deflecting during the movement and avoid the protective door being unable to open or close smoothly.

[0030] As a preferred embodiment, the connecting device includes a connecting component and a guide component; the bottom of the protective door is connected to a door panel through the connecting component; the guide component is connected to the side of the power exchange platform facing the protective door, and the protective door can be translated under the driving action of the driving device until the connecting component is abutted against the guide component, and the connecting component moves along the guide component to drive the protective door to move upward until it is flush with the power exchange platform.

[0031] In this solution, a door panel is provided at the bottom of the protective door, and a connecting component is connected between the door panel and the protective door. The connecting component realizes effective support of the protective door, and at the same time, the door panel and the protective door are hingedly connected, and the protective door can be pushed upward relative to the door panel under the drive of the guide component so that the protective door is flush with the top surface of the battery swap platform. The guide component is connected to the battery swap platform, and serves as a fulcrum for the upward movement of the connecting component. The position where the guide component is set can be in conflict with the connecting component moved to the guide component, and when the connecting component moves along the guide component, it can drive the door panel and the protective door to move upward, so that the protective door and the door panel move to be flush with the top surface of the battery swap platform; the purpose of the protective door being flush with the top surface of the battery swap platform is to avoid the protective door being lower than the height of the battery swap platform, which causes the driver to see a visual pit when driving into the battery swap platform and dare not drive into the battery swap platform. At the same time, the protective door is flush with the battery swap platform, making the battery swap platform smoother and more beautiful, and increasing the user experience.

[0032] As a preferred embodiment, the connecting assembly includes a first connecting rod bracket and a second connecting rod bracket hingedly connected between the protective door and the door panel; when the first connecting rod bracket moves to abut against the guide assembly, it can drive the protective door to move upward to be flush with the battery exchange platform under the guidance of the guide assembly.

[0033] In this solution, the first connecting rod bracket and the second connecting rod bracket are connected between the protective door and the door panel, which can provide two-point support between the protective door and the door panel, thereby avoiding an imbalance in the connection between the protective door and the door panel, which causes the protective door to be tilted relative to the door panel. The first connecting rod bracket and the second connecting rod bracket are both hingedly connected between the protective door and the door panel, so that a certain moving space can be provided between the protective door and the door panel, which is conducive to the upward movement of the protective door relative to the door panel, so that the protective door is flush with the top surface of the battery exchange platform.

[0034] As a preferred embodiment, the connecting device also includes a connecting seat, which is connected to the bottom of the door panel along the length direction of the door panel, and the driving device is installed in the connecting seat.

[0035] In the present solution, the connecting seat is arranged under the door panel, so that the driving device can be connected to the bottom of the door panel through the connecting seat. The driving device is fixed by the connecting seat, which increases the stability and disassembly of the connection between the driving device and the door panel. The connection between the driving device and the door panel is more flexible. The driving device and the connecting seat can be connected by a pin shaft or a rotating shaft. When the driving device drives the door panel to move, there can be a certain rotation margin relative to the door panel. When the door panel is locally slightly deformed and bulges downward, since the driving device has a certain rotation margin relative to the door panel, it will not interfere with the door panel, thereby reducing the friction between the driving device and the door panel.

[0036] As a preferred embodiment, the guide assembly includes a pulley bracket and a pulley connected to each other; the pulley bracket is connected to the side of the power exchange platform facing the door panel, and the first connecting rod bracket is abutted against the pulley.

[0037] In this solution, a pulley bracket rotatably connected to a pulley is connected to the side of the battery exchange platform facing the door panel, so that the first connecting rod bracket of the connecting assembly can abut against the pulley on the pulley bracket, and since the first connecting rod bracket is obliquely connected between the door panel and the protective door, the first connecting rod bracket can move upward along the pulley when moving along the pulley, thereby driving the protective door to move upward to be flush with the top surface of the battery exchange platform.

[0038] As a preferred embodiment, the first connecting rod bracket has a first connecting section and a second connecting section along the length direction; the second connecting section has an arc transition surface on the side facing the battery exchange platform, so that the door panel moves upward along the arc transition surface to be flush with the battery exchange platform.

[0039] In this solution, the first connecting rod bracket has a first connecting section and a second connecting section. The purpose is that the second connecting section of the first connecting rod bracket first contacts the pulley and slides upward along the pulley. The second connecting section has an arc transition surface on the side facing the battery exchange platform, which can be used as an entry surface with the pulley. When the second connecting rod bracket moves to the position of the pulley and abuts against the pulley, the second connecting section has an upward curved action surface because it is an arc transition surface. When the action surface contacts the pulley and slides relative to the pulley, the first connecting rod bracket moves upward, driving the protective door to move upward, and finally the protective door is flush with the top surface of the battery exchange platform.

[0040] As a preferred embodiment, the connecting rod assembly includes a first connecting rod assembly and a second connecting rod assembly; the first connecting rod assembly is connected between the protective door and the door panel; the second connecting rod assembly can, when moved to abut against the longitudinal beam of the battery exchange platform, push the protective door upward to be flush with the battery exchange platform.

[0041] In this solution, the first connecting rod assembly is connected between the protective door and the door panel, and the protective door is supported by the first connecting rod assembly. The protective door can move freely at a certain angle relative to the door panel under the action of the first connecting rod assembly, so that there is a moving space between the protective door and the door panel, thereby ensuring that the protective door can move upward relative to the door panel so that the protective door remains flush with the top surface of the battery exchange platform; the second connecting rod assembly can be linked with the protective door and the door panel, and when the door panel and the protective door move to a position where the second connecting rod assembly abuts against the longitudinal beam of the battery exchange platform, the second connecting rod assembly can support the protective door, lift the protective door upward relative to the door panel, and thus achieve that the protective door remains flush with the top surface of the battery exchange platform.

[0042] As a preferred embodiment, the first connecting rod assembly includes a first connecting rod and a second connecting rod respectively hingedly connected to the door panel and the protective door;

[0043] The second connecting rod assembly includes a third connecting rod and a pulley in a V-shaped structure, the third connecting rod having a connecting end, a positioning end and a guide end; the connecting end is hingedly connected to the top of the door panel, the wire end is rotatably connected to the first wheel, and the longitudinal beam of the power exchange platform is rotatably connected to the second wheel; when the door panel moves to make the positioning end abut against the second wheel, the guide end rotates to make the first wheel abut against the bottom of the door panel, and the door panel and the protective door can move upward under the abutting action of the first wheel to be flush with the power exchange platform.

[0044] In this solution, the first connecting rod assembly includes a first connecting rod and a second connecting rod hingedly connected between the door panel and the protective door, so as to achieve stable support on both sides of the protective door and realize a certain movement of the protective door relative to the door panel. The height distance between the protective door and the door panel is adjustable, thereby ensuring that the protective door moves upward relative to the door panel, so that the protective door is flush with the top surface of the power exchange platform; the second connecting rod assembly includes a V-shaped third connecting rod, and the protruding end of the third connecting rod is arranged downward as a connecting end with the door panel, and the positioning end and the guide end extend upward at an angle respectively. The positioning end on one side can be positioned and kept in position, and the guide end on the other side can push against the bottom of the protective door, so that the guide end can realize an upward pushing effect on the protective door, thereby realizing the upward movement of the protective door until it is flush with the top surface of the power exchange platform.

[0046] In this solution, the lead screw and the slide rail are respectively connected to a slider, and the slider can move along the lead screw and the slide rail at the same time. The lead screw is driven by a motor to drive the slider to move along the lead screw, so that the slider can move along the slide rail. The slider is connected to the bottom of the door panel and can drive the door panel to translate along the slide rail, thereby realizing the horizontal displacement of the door panel and the protective door along the power exchange platform; ensuring the straight movement path of the protective door and the door panel, and ensuring that the protective door and the door panel always move in a straight line along the established route during the movement process without deflection.

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0083] like Figures 1 to 17 As shown, the present application provides a battery swap platform 1, a shuttle channel 2 for the movement of a battery swap vehicle is arranged at the bottom of the battery swap platform 1, a battery swap port 3 is opened on the battery swap platform 1 for the battery swap vehicle to be lifted and moved for battery swap operations, and the battery swap port 3 has a protective door 4 and a driving device 5, and the driving device 5 drives the protective door 4 to move to open or close the battery swap port 3.

[0084] It should be noted that the battery exchange platform 1 can be a frame structure constructed by a bracket and a patterned steel cover plate, or it can be a closed three-dimensional structure formed by connecting patterned steel cover plates. The specific shape and construction method are not limited by this embodiment.

[0085] The battery swap platform 1 is used for parking vehicles. When the vehicle is docked at the battery swap platform 1, a shuttle channel 2 is provided at the bottom of the battery swap platform 1 to allow the battery swap vehicle to enter and exit freely. The battery swap vehicle reaches the battery swap port 3 in the shuttle channel 2, and the chassis battery of the vehicle is located opposite the battery swap port 3. A battery swap port 3 is provided in the middle of the battery swap platform 1 for the vehicle to perform battery swap operations. The purpose of setting the battery swap port 3 is to facilitate exposing the vehicle chassis for the vehicle located below the battery swap port 3 to perform battery swap operations; a protective door 4 is connected to the battery swap port 3, and the protective door 4 is movably connected to the battery swap platform 1 to enable the protective door 4 to be opened to open the battery swap port 3 or to be closed to close the battery swap port 3. When the protective door 4 is opened to put the battery swap port 3 in an open state, the battery swap vehicle is located below the battery swap port 3 to perform battery swap operations on the battery at the bottom of the vehicle.

[0086] Through the above arrangement, the battery swap platform 1 can be located under the ground. When the top surface of the battery swap platform 1 is flush with the ground, the vehicle does not need to be lifted by the lifting mechanism or driven into the ramp to lift the vehicle. The driver can drive the vehicle into the battery swap platform 1 as if driving on the ground, and the driver can get off the vehicle or stay in the cab during the entire battery swap operation, which provides a good user experience. The battery swap vehicle is sunk into the underground space and will not interfere with the components and vehicles on the ground; a shuttle channel 2 for the battery swap vehicle to move is set below the battery swap platform 1. The battery swap vehicle can shuttle in the shuttle channel 2 under the ground and run to the bottom of the battery swap port 3 of the battery swap platform 1. When the protective door 4 is opened, the battery swap port 3 is in an open state. The battery swap vehicle can contact the bottom of the battery swap vehicle through the battery swap port 3 and disassemble and replace the battery at the bottom of the battery swap vehicle accordingly; when the battery swap vehicle is finished swapping, it drives away from the battery swap port 3 through the shuttle channel 2, and the protective door 4 is closed to close the battery swap port 3. A movable protective door 4 is provided. When a battery swap operation is required, the protective door is opened to keep the battery swap port open. When a battery swap operation is not required, the protective door is closed. On the one hand, it can protect the battery swap port 3 and effectively prevent garbage or other debris from falling into the battery swap port 3 to cause environmental pollution. On the other hand, it can effectively prevent people from accidentally entering the battery swap port 3 and causing injuries, thereby increasing safety. On the other hand, it can also prevent the driver from seeing a pit when driving the vehicle into the battery swap platform 1 and not daring to continue driving forward, thereby increasing the user experience.

[0087] Implementation method 1: Figures 1 to 3 As shown, the protective door 4 has a folding portion 6, and the folding portion 6 is connected to a connecting device; the driving device 5 drives the folding portion 6 to extend or fold through the connecting device.

[0088] In this solution, the protective door 4 is provided with a folding portion 6 with accordion folds, so that the folding portion 6 can be folded and stored from one side to the other side when the protective door 4 is opened, so that the protective door can be completely stored on one side, and can even be completely hidden in the wall of the battery exchange platform 1, thereby reducing the space occupied by the protective door 4 and making the space look more open. The layered contraction folding method is more flexible and changeable, which will also increase the user experience. When the protective door 4 needs to be closed, the folding portion 6 gradually extends layer by layer from the contracted side, like a flowing wave line, which increases the visual beauty and increases the user experience.

[0089] Preferably, if Figure 1 As shown, the connecting device includes a connecting bracket 7 respectively connected to the folding part 6 and a plurality of connecting blocks 8 arranged along the length direction of the folding part 6; the connecting bracket 7 is connected to the driving device 5; and the connecting block 8 is movably connected to the battery exchange platform 1.

[0090] Specifically, the connecting bracket 7 is connected to the bottom of the movable end of the folding portion 6, a circular through hole is provided on the connecting bracket 7, and a connecting through hole is provided at the driving end of the driving device 5 corresponding to the circular through hole, and the driving end is fixedly connected to the connecting bracket 7 by passing a pin shaft or a fixing member through the circular through hole and the connecting through hole. The driving end of the driving device 5 pushes the movable end of the folding portion 6 toward the fixed end of the folding portion 6 to fold, so that the movable end and the fixed end of the folding portion 6 are both located on one side of the battery swap platform 1, and the entire battery swap port 3 is opened; when the battery swap port 3 needs to be closed, the driving end of the driving device 5 makes a return motion so that the movable end of the folding portion 6 moves toward the side away from the fixed end of the folding portion 6, and finally the folding portion 6 completely covers the battery swap port 3.

[0091] In this solution, the driving device 5 is connected to the protective door 4 through the connecting bracket 7, and the driving device 5 drives the protective door 4 to unfold or fold toward one side in sequence through the connecting bracket 7; the connecting block 8 is connected to the bottom of the protective door 4 to support the protective door 4; the connecting block 8 is movably connected to the power exchange platform 1 to guide the protective door 4, so that the protective door 4 can translate along the power exchange platform 1, further realizing the extension or folding movement of the protective door 4.

[0092] Preferably, the battery exchange platform 1 is provided with a track protruding toward the folding portion 6; or, the battery exchange platform 1 is provided with a track protruding upward, and the connecting block 8 is movably connected to the track.

[0093] Embodiment 1: A raised track is provided on the inner side of the battery exchange platform 1 along the length direction of the battery exchange platform 1, and the track is opposite to the two side edges of the protective door 4; a positioning block is connected to the outer side of the protective door 4 along the length direction, and the positioning block is movably connected to the track. The protective door 4 can be translated along the track through the positioning block to realize the opening or closing of the protective door 4 relative to the battery exchange port 3.

[0094] Embodiment 2: A track protruding upward is provided on the inner side of the battery exchange platform 1 along the length direction of the battery exchange platform 1, and the track is located at the bottom of the protective door 4; a positioning block movably connected to the track is connected to the bottom of the protective door 4 corresponding to one side of the track, and the protective door 4 can be moved along the top of the track through the positioning block to realize the opening or closing of the protective door 4 relative to the battery exchange port 3.

[0095] In this solution, the battery exchange platform 1 is provided with a track protruding toward the folding portion 6, so that the horizontal side of the folding portion 6 of the protective door 4 is movably connected to the battery exchange platform 1. At this time, the connecting block 8 is connected to the side of the protective door 4, and is movably connected to the track protruding toward the folding portion 6 of the battery exchange platform 1 through the connecting block 8, so that the protective door 4 is supported in the horizontal direction, thereby protecting the protective door 4 from sliding smoothly in the horizontal direction, and does not cause uneven force on both sides of the protective door 4, resulting in one side of the protective door 4 being squeezed, causing the protective door 4 to be skewed, and jamming when extending or folding in the horizontal direction; or, A track protruding upward is provided in the battery exchange platform 1. At this time, a connecting block 8 is connected to the bottom of the protective door 4, so that the protective door 4 can be moved and connected to the upward track of the battery exchange platform 1 through the connecting block 8 at the bottom, ensuring that the protective door 4 is subjected to equal support force in the vertical plane, so that the protective door 4 is not easy to cause local collapse in the vertical plane, thereby avoiding resistance when the driving device 5 drives the protective door 4 to move horizontally; whether supporting the horizontal side of the protective door 4 or supporting the bottom surface of the protective door 4, the protective door 4 can be protected, ensuring that the protective door 4 opens or closes more smoothly, thereby improving the battery exchange efficiency.

[0096] Example 3: Figure 3 As shown, relatively distributed grooves 9 are provided in the battery exchange platform 1 , and a roller 10 is sleeved on the connecting block 8 , and the roller 10 moves along the groove 9 .

[0097] Specifically, Figure 3 As shown, a groove 9 is provided on the inner side of the battery exchange platform 1 facing the side of the protective door 4, and the groove 9 is provided along the length direction of the battery exchange platform 1; connecting blocks 8 are respectively connected to both sides of the protective door 4 along the length direction, and rollers 10 are rotatably connected to the connecting blocks 8, and the rollers 10 can roll in the groove 9 to drive the protective door 4 to translate along the groove 9.

[0098] In this solution, a groove 9 is provided inside the battery exchange platform 1, and the connecting block 8 is connected to a roller 10 for movably connecting to the groove 9. When the protective door 4 is extended or folded, the roller 10 rolls in the groove 9 to drive the protective door 4 to move along the groove 9 of the battery exchange platform 1; the recessed setting of the groove 9 on the battery exchange platform 1 reduces the space occupied by the battery exchange platform 1, and can realize the embedded connection between the protective door 4 and the battery exchange platform 1, thereby reducing the distance between the protective door 4 and the battery exchange platform 1, reducing dust intrusion, and being more conducive to cleaning. The hidden design makes the appearance more beautiful and increases the user experience.

[0099] Implementation method 2: Figure 4-5As shown, the protection door 4 includes a first protection door and a second protection door; the first protection door and the second protection door are respectively connected to the connecting device;

[0100] like Figure 5 As shown, the connecting device includes a rotating shaft 11 and a plurality of support rods 12; the rotating shaft 11 is rotatably connected to the battery exchange platform 1 at both ends along the axial direction, and the driving device 5 is connected to the rotating shaft 11 through a rotating connecting piece 13; the first end of the support rod 12 is connected to the rotating shaft 11, and the second end of the support rod 12 is hingedly connected to the protective door 4, and the protective door 4 can rotate relative to the battery exchange platform 1 under the rotation action of the rotating shaft 11 to open or close the battery exchange port 3.

[0101] It should be noted that the number of the support rods 12 is not limited by the present embodiment. In order to maintain the balance of the protective door 4 during the rotation process, the number of the support rods 12 is not less than two. In the present embodiment, two support rods 12 are used.

[0102] Specifically, Figure 5 As shown, the rotating connector 13 has a certain curvature, one end of the rotating connector 13 is connected to the driving end of the driving device 5, and the other end of the rotating connector 13 is connected to the rotating shaft 11; the fixed block 14 is fixedly connected to the inner side of the power exchange platform 1, and the two ends of the rotating shaft 11 along the axial direction are rotatably connected to the fixed block 14, and the rotating shaft 11 is rotatably connected to the power exchange platform 1 through the fixed block 14. The peripheral side of the rotating shaft 11 is connected to the driving device 5 through the rotating connector 13, and the position of the rotating shaft 11 relative to the rotating connector 13 is connected to the support rod 12, one end of the support rod 12 is fixedly connected to the rotating shaft 11, and the other end is hingedly connected to the bottom of the protective door 4;

[0103] The structure of the support rod 12 is not limited by the present embodiment and can adopt any one of the following embodiments:

[0104] Embodiment 1: The support rod 12 adopts a linear structure, one end of the support rod 12 is connected to the rotating shaft 11, and the other end of the support rod 12 is hingedly connected to the bottom of the protective door 4; when the rotating shaft 11 rotates toward the outside of the power exchange platform 1, the first protective door or the second protective door is driven by the support rod 12 to move toward the outside of the power exchange platform 1. Since one end of the support rod 12 is fixedly connected to the rotating shaft 11, the first protective door or the second protective door is driven to move toward the outside, and the other end of the support rod 12 is hingedly connected to the first protective door or the second protective door. When the first protective door or the second protective door moves toward the outside driven by the support rod 12, it falls inwardly and downward under the action of its own gravity. The middle part of the protective door 4 makes a circular motion, and the two sides of the protective door 4 along the length direction make smooth motions respectively, so that the protective door 4 forms an inward swing door structure toward the inside and maintains a vertical state with the power exchange platform 1.

[0105] Example 2: Figure 5 As shown, the support rod 12 has a first positioning end 15 and a second positioning end 16; a downwardly protruding curved portion 17 is provided between the first positioning end 15 and the second positioning end 16, and the curved portion 17 has a certain curvature. The first positioning end 15 of the support rod 12 is fixedly connected to the rotating shaft 11, and the second positioning end 16 of the support rod 12 is hingedly connected to the bottom of the protective door 4; when the rotating shaft 11 rotates toward the outside of the power exchange platform 1, the first protective door or the second protective door is driven to move toward the outside of the power exchange platform 1 through the second positioning end 16 of the support rod 12. Since the second positioning end 16 needs to avoid the first protective door or the second protective door The door opening frame of the protective door, so the second positioning end 16 is designed to have a downwardly protruding curved portion 17. In this way, the second positioning end 16 bypasses the door opening frame and moves to the outside of the door opening frame of the battery exchange platform 1, so that the first protective door or the second protective door moves to the outside of the battery exchange platform 1; in order to further realize that the first protective door or the second protective door can be moved parallel to the outside of the battery exchange platform 1, preferably, the connecting device also includes a pull rod 18. As a preferred embodiment, the first end of the pull rod 18 is hingedly connected to the protective door 4, and the second end of the pull rod 18 is hingedly connected to the battery exchange platform 1.

[0106] The pull rod 18 and the support rod 12 together form a four-bar linkage that allows the first protective door or the second protective door to have a certain motion trajectory, so that the first protective door or the second protective door forms an outward swing door, so that the first protective door or the second protective door is located outside the battery swap platform in a horizontal state after opening, and remains parallel to the battery swap platform. It is worth noting here that the distance between the first protective door or the second protective door and the top surface of the battery swap platform 1 after parallel movement needs to be smaller than the distance between the bottom of the vehicle and the battery swap platform 1, so as to prevent the first protective door or the second protective door from being unable to fully open to form an outward swing door structure. The length of the pull rod 18 and the length of the support rod 12 can be adjusted according to the height range of the first protective door or the second protective door.

[0107] In this solution, the pull rod 18 is arranged between the protective door 4 and the battery exchange platform 1 to support the protective door 4 above the battery exchange platform 1, thereby preventing the protective door 4 from partially tilting during the movement relative to the battery exchange platform 1, causing failure of the protective door 4 when opening or closing. The pull rod 18 is hingedly connected to the protective door 4 and the battery exchange platform 1, so that the protective door 4 can rotate freely relative to the battery exchange platform 1, and the protective door 4 can move to a preset angle relative to the battery exchange platform 1 under the connecting action of the pull rod 18, and the opening angle and position of the protective door 4 are restricted to avoid the protective door 4 from rotating too much and being unable to close, thereby increasing the safety and stability of the protective door 4.

[0108] In addition, in the present scheme, the protective door 4 is configured to include a first protective door and a second protective door, and is connected to the connecting device through the first protective door and the second protective door, respectively, so that the first protective door and the second protective door can be opened or closed to both sides, respectively, thereby reducing the waiting time for closing or opening; the peripheral side of the rotating shaft 11 is connected to the driving device 5, so that the driving device 5 drives the rotating shaft 11 to rotate, and the protective door 4 and the rotating shaft 11 are respectively connected through the support rod 12, so that when the rotating shaft 11 rotates, the protective door 4 is driven by the support rod 12 to rotate relative to the battery exchange platform 1, thereby realizing the rapid opening or closing of the protective door 4, and the protective door 4 can be opened or closed by only starting the rotating shaft 11 to rotate counterclockwise or clockwise, thereby improving the battery exchange efficiency.

[0109] Preferably, the first protective door and the second protective door are arranged along the width direction of the power exchange platform 1; or, the first protective door and the second protective door are arranged along the length direction of the power exchange platform 1.

[0110] In this solution, the first protective door and the second protective door can be arranged along the length direction of the battery exchange platform 1, so as to increase the layout space of the driving device 5 and the connecting device; the first protective door and the second protective door can also be arranged along the width direction of the battery exchange platform 1 to reduce the moving distance of the protective door 4 and increase the battery exchange efficiency.

[0111] Implementation method three: Figures 6 to 9 As shown, the connecting device includes a connecting plate 19 connected to the battery exchange platform 1 and a movable component 20 connected to the protective door 4; the movable component 20 is movably connected to the connecting plate 19, and the protective door 4 can be translated along the connecting plate 19 through the movable component 20 under the driving action of the driving device 5 to open or close the battery exchange port 3.

[0112] Specifically, the connecting plate 19 can be a plate-shaped structure, with both sides of the connecting plate 19 in the length direction connected to the bottom of the battery exchange port 3 of the battery exchange platform 1, and the connecting plate 19 is vertically arranged below the protective door 4; the driving device 5 is directly connected to the protective door 4, and the protective door 4 is movably connected to the connecting plate 19 through the moving component 20, and the driving device 5 drives the protective door 4 to move in a straight line along the connecting plate 19, thereby realizing the opening or closing of the battery exchange port 3.

[0113] In this solution, the connecting plate 19 is connected to the battery exchange platform 1 and is located below the protective door 4, which effectively supports the protective door 4 and prevents the protective door 4 from collapsing in the horizontal plane and being unable to operate stably; and the connecting plate 19 serves as a guide for the protective door 4 and has the function of guiding the moving position of the protective door 4. The connecting plate 19 can ensure the moving path of the protective door 4, so that the protective door 4 can move horizontally according to the predetermined moving path, and the protective door 4 can be translated along the connecting plate 19 to be opened or closed, thereby ensuring the safety and convenience of the smooth operation of the protective door 4 and improving the battery exchange efficiency.

[0114] Example 1: Figure 7 As shown, a guide track 21 is provided in the extension direction of the connecting plate 19; the moving assembly 20 includes a first connecting member 201, a second connecting member 202 and a guide roller 203; one end of the first connecting member 201 and the second connecting member 202 are respectively connected to the protective door 4, and the other ends of the first connecting member 201 and the second connecting member 202 are rotatably connected to the guide roller 203, and the guide roller 203 is rollingly connected to the guide track 21.

[0115] Specifically, the first connecting member 201 and the second connecting member 202 are rod-shaped structures, and the connecting plate 19 is obliquely connected to the bottom of the protective door 4. The first connecting member 201 and the second connecting member 202 are symmetrically arranged and spaced a certain distance apart. The purpose is to connect the guide roller 203 between the first connecting member 201 and the second connecting member 202. Through holes are respectively opened at one end of the bottom of the first connecting member 201 and the second connecting member 202, and bearings are connected in the through holes. The two ends of the axial direction of the guide roller 203 are respectively rotatably connected in the through holes through bearings. During installation, the circumferential surface of the conductive roller is first inserted into the guide track 21 in the connecting plate 19. When the driving device 5 drives the protective door 4 to move to one side, the guide roller 203 moves along the guide track 21 in the direction of the same side as the protective door 4, thereby realizing the linear movement of the protective door 4 along the guide track 21 of the connecting plate 19, thereby realizing the opening and closing of the power exchange port 3.

[0116] In this solution, a guide track 21 for guiding the movement direction of the protective door 4 is provided inside the connecting plate 19; the moving assembly 20 connected to the bottom of the protective door 4 is moved and connected to the guide track 21, so that the protective door 4 is driven to reciprocate along the guide track 21 of the connecting plate 19 by the moving assembly 20, thereby realizing the opening and closing of the protective door 4. The guide track 21 can ensure the movement path of the protective door 4, and prevent the protective door 4 from being offset during the movement, which may cause the protective door 4 to fail to open and close smoothly; and the first connecting member 201 and the second connecting member 202 are fixedly connected to the bottom of the protective door 4, and the guide roller 203 is connected between the first connecting member 201 and the second connecting member 202, and the guide roller 203 is rollingly connected in the guide track, further providing a stable support force for the protective door 4, so that the protective door 4 can run smoothly along the guide track 21, thereby improving the battery replacement efficiency.

[0117] Preferably, if Figure 7 As shown, the closed end of the guide rail 21 is provided with an upwardly curved arc transition section 22 so that the protective door 4 rises along the arc transition section 22 of the guide rail 21 to be flush with the top surface of the battery exchange platform 1.

[0118] Specifically, the guide track 21 has two ends along the extension direction, wherein the end facing the door frame of the power exchange port 3 is the starting end. The guide track 21 here can be open, that is, the guide track 21 and the connecting plate 19 are not closed but open, or the starting end of the guide track 21 can be designed to be closed; the end of the guide track 21 facing the center of the power exchange port 3 is the closed end, and the power exchange port 3 can be closed when the protective door 4 moves toward the closed end; in order to achieve the top surface height of the protective door 4 to be consistent with the height of the power exchange platform 1 The top surface height is consistent, that is, the top surface of the battery exchange platform 1 and the top surface of the protective door 4 are on the same horizontal plane. When the protective door 4 needs to be moved toward the center position of the battery exchange port 3, it also has an upward movement. Therefore, the closed end of the guide rail 21 is designed to have an upward curved arc transition section 22, so that the guide roller 203 moves upward in a circular trajectory. The protective door 4 moves upward in parallel under the drive of the first connecting member 201, the second connecting member 202 and the guide roller 203, so that the top surface of the protective door 4 is flush with the top surface of the battery exchange platform 1.

[0119] In this solution, in order to enable the first protective door and the second protective door to close in the middle when running along the guide track 21, the guide track 21 needs to extend to the middle of the power exchange platform 1, and one end extending to the middle of the power exchange platform 1 serves as the closed end of the guide track 21; in order to enable the first protective door and the second protective door on both sides to achieve the top surface flush with the top surface of the power exchange platform 1 under the guiding action of the closed end, the closed end of the guide track 21 is set to have an upward curved arc transition section 22. When the first protective door and the second protective door on both sides approach the middle for closing, the guide rollers 203 at the bottom of the first protective door and the second protective door move along the circular arc transition section 22. Since the circular arc transition section 22 is bent upward, the guide rollers 203 can push the first protective door and the second protective door to move upward, and finally the top surfaces of the first protective door and the second protective door are flush with the top surface of the power exchange platform 1.

[0120] Specifically, Figure 8 As shown, a guide rail 23 is provided on the inner side of the battery exchange platform 1 , and the protective door 4 is rotatably connected to a roller 24 on one side of the guide rail 23 through a positioning piece, and the roller 24 rolls along the guide rail 23 .

[0121] In this solution, a guide rail 23 is arranged on the power exchange platform 1, and the protective door 4 is provided with a roller 24 which is rollingly connected to the guide rail 23, so that the protective door 4 can move along the guide rail 23 of the power exchange platform 1, thereby further increasing the supporting force of the protective door 4. In addition, the protective door 4 can move along a predetermined route under the guidance of the guide rail 23, thereby protecting the protective door 4 from deviation during the movement, thereby preventing the protective door 4 from being unable to open or close smoothly.

[0122] Example 2: Figures 10 to 13 As shown, the connecting device includes a connecting component 25 and a guide component 26; the bottom of the protective door 4 is connected to a door panel 30 through the connecting component 25; the guide component 26 is connected to the side of the power exchange platform 1 facing the protective door 4, and the protective door 4 can be translated under the driving action of the driving device 5 until the connecting component 25 is abutted against the guide component 26, and the connecting component 25 moves along the guide component 26 to drive the protective door 4 to move upward until it is flush with the power exchange platform 1.

[0123] In this solution, a door panel 30 is provided at the bottom of the protective door 4, and a connecting component 25 is connected between the door panel 30 and the protective door 4. The connecting component 25 realizes effective support of the protective door 4. At the same time, the door panel 30 and the protective door 4 are hingedly connected, and can be driven by the guide component 26 to push the protective door 4 upward relative to the door panel 30 so that the protective door 4 is flush with the top surface of the power exchange platform 1. The guide component 26 is connected to the battery exchange platform 1 and serves as a fulcrum for the upward movement of the connecting component 25. The position at which the guide component 26 is set can be in contact with the connecting component 25 moved to the guide component 26, and can enable the connecting component 25 to drive the door panel 30 and the protective door 4 to move upward when moving along the guide component 26, so that the protective door 4 and the door panel 30 move to be flush with the top surface of the battery exchange platform 1; the purpose of the protective door 4 being flush with the top surface of the battery exchange platform 1 is to avoid the protective door 4 being lower than the height of the battery exchange platform 1, which will cause the driver to see a visual pit when driving into the battery exchange platform 1 and dare not drive into the battery exchange platform 1. At the same time, the protective door 4 is flush with the battery exchange platform 1, which makes the battery exchange platform 1 more flat and beautiful, thereby increasing the user experience.

[0124] Example 1: Fig.11 and Fig.12 As shown, the connecting assembly 25 includes a first connecting rod bracket 251 and a second connecting rod bracket 252 which are hingedly connected between the protective door 4 and the door panel 30; when the first connecting rod bracket 251 moves to abut against the guide assembly 26, it can drive the protective door 4 to move upward to be flush with the battery exchange platform 1 under the guiding action of the guide assembly 26.

[0125] Specifically, the protective door 4 includes a first protective door and a second protective door arranged along the length direction, and the structures of the first protective door and the second protective door are the same. Here, the first protective door is used as an example for explanation. The bottom of the first protective door is rotatably connected by a first connecting rod bracket 251 and a second connecting rod bracket 252. The first connecting rod bracket 251 and the second connecting rod bracket 252 are respectively located on both sides of the first protective door, wherein the first connecting rod bracket 251 is close to the opening and closing side of the first protective door. When the first connecting rod bracket 251 and the first protective door perform a closing movement toward the middle of the power exchange port 3 together, the first connecting rod bracket 251 can be abutted and connected with the guide assembly 26 connected to the power exchange platform 1, and the first connecting rod bracket 251 can move upward along the guide assembly 26, so that the first protective door is driven by the first connecting rod bracket 251 to make an upward parallel movement, thereby realizing that the first protective door is flush with the top surface of the power exchange platform 1. Similarly, the second protective door moves relative to the first protective door, so that the top surface of the second protective door remains flush with the top surface of the power exchange platform 1.

[0126] In this solution, the first connecting rod bracket 251 and the second connecting rod bracket 252 are connected between the protective door 4 and the door panel 30, which can provide two-point support between the protective door 4 and the door panel 30, thereby avoiding an imbalance in the connection between the protective door 4 and the door panel 30, which would cause the protective door 4 to be tilted relative to the door panel 30. The first connecting rod bracket 251 and the second connecting rod bracket 252 are both hingedly connected between the protective door 4 and the door panel 30, so that a certain amount of moving space can be provided between the protective door 4 and the door panel 30, thereby facilitating the upward movement of the protective door 4 relative to the door panel 30, so that the protective door 4 is flush with the top surface of the battery exchange platform 1.

[0127] The connecting device further comprises a connecting seat, which is connected to the lower side of the door panel 30 along the length direction of the door panel 30 , and the driving device 5 is installed in the connecting seat.

[0128] In this solution, the connection seat is arranged below the door panel 30, so that the drive device 5 can be connected to the below of the door panel 30 through the connection seat, and the drive device 5 is fixed through the connection seat, which increases the stability and detachability of the connection between the drive device 5 and the door panel 30, and the connection between the drive device 5 and the door panel 30 is more flexible, and the drive device 5 and the connection seat can be connected through a pin. When the drive device 5 drives the door panel 30 to move, there can be a certain rotation margin relative to the door panel 30. When the door panel 30 is partially slightly deformed and bulges downward, since the drive device 5 has a certain rotation margin relative to the door panel 30, it will not interfere with the door panel 30, thereby reducing the friction between the drive device 5 and the door panel 30.

[0129] like Fig.12 As shown, the guide assembly 26 includes a pulley bracket 261 and a pulley 262 connected to each other; the pulley bracket 261 is connected to the side of the power exchange platform 1 facing the door panel 30, and the first connecting rod bracket 251 is abutted and connected to the pulley 262.

[0130] In this solution, a pulley bracket 261 rotatably connected to a pulley 262 is connected to the side of the battery exchange platform 1 facing the door panel 30, so that the first connecting rod bracket 251 of the connecting assembly 25 can abut against the pulley 262 on the pulley bracket 261, and since the first connecting rod bracket 251 is obliquely connected between the door panel 30 and the protective door 4, the first connecting rod bracket 251 can move upward along the pulley 262 when moving along the pulley 262, thereby driving the protective door 4 to move upward to be flush with the top surface of the battery exchange platform 1.

[0131] Preferably, if Fig.13As shown, the first connecting rod bracket 251 has a first connecting section 2511 and a second connecting section 2512 along the length direction; the second connecting section 2512 has an arc transition surface 28 on the side facing the battery exchange platform 1, so that the door panel 30 moves upward along the arc transition surface 28 to be flush with the battery exchange platform 1.

[0132] In this solution, the first connecting rod bracket 251 has a first connecting section 2511 and a second connecting section 2512. The purpose is that the second connecting section 2512 of the first connecting rod bracket 251 first contacts the pulley 262 and slides upward along the pulley 262. The second connecting section 2512 has an arc transition surface 28 on the side facing the power exchange platform 1, which can be used as an entry surface with the pulley 262. When the second connecting rod bracket 252 moves to the position of the pulley 262 and abuts against the pulley 262, the second connecting section 2512 has an upward curved action surface because it is an arc transition surface 28. When the action surface contacts the pulley 262 and slides relative to the pulley 262, the first connecting rod bracket 251 moves upward to drive the protective door 4 to move upward, and finally the protective door 4 is flush with the top surface of the power exchange platform 1.

[0133] Specifically, Fig.12 As shown, the connecting device also includes a sliding assembly 29, which includes a sliding rail 291 connected to the battery exchange platform 1 and a sliding block 292 movably connected to the sliding rail 291, and the sliding block 292 is connected to the bottom of the door panel 30 to drive the door panel 30 to translate along the sliding rail 291.

[0134] Example 2: Figures 14 to 17 As shown, the connecting rod assembly 25 includes a first connecting rod assembly 253 and a second connecting rod assembly 254; the first connecting rod assembly 253 is connected between the protective door 4 and the door panel 30; the second connecting rod assembly 254 can push the protective door 4 to move upward until it is flush with the battery exchange platform 1 when it moves to abut against the longitudinal beam 32 of the battery exchange platform 1.

[0135] In this solution, the first connecting rod assembly 253 is connected between the protective door 4 and the door panel 30, and the protective door 4 is supported by the first connecting rod assembly 253. The protective door 4 can freely move at a certain angle relative to the door panel 30 under the action of the first connecting rod assembly 253, so that there is a moving space between the protective door 4 and the door panel 30, thereby ensuring that the protective door 4 can move upward relative to the door panel 30 so that the protective door 4 remains flush with the top surface of the battery exchange platform 1; the second connecting rod assembly 254 can be linked with the protective door 4 and the door panel 30, and when the door panel 30 and the protective door 4 move to the position where the second connecting rod assembly 254 abuts against the longitudinal beam 32 of the battery exchange platform 1, the second connecting rod assembly 254 can play a role in supporting the protective door 4, and push the protective door 4 upward relative to the door panel 30, so that the protective door 4 remains flush with the top surface of the battery exchange platform 1.

[0136] Specifically, the protective door 4 includes a first protective door and a second protective door arranged along the length direction. The first protective door and the second protective door have the same structure, and the first protective door is taken as an example for description. Fig.14 As shown, the first connecting rod 2531 and the second connecting rod 2532 are respectively connected to the two sides of the moving direction of the door panel 30, and the first connecting rod 2531 and the second connecting rod 2532 are hingedly connected between the door panel 30 and the protective door 4 to realize the rotation between the first protective door and the door panel 30;

[0137] The second connecting rod assembly 254 includes a third connecting rod 2541 with a V-shaped structure and a first rotating wheel 2542. The third connecting rod 2541 has a connecting end, a positioning end and a guiding end. There is a certain angle between the positioning end and the guiding end. The guiding end is rotatably connected to the first rotating wheel 2542. The connecting end is hingedly connected to the top of the door panel 30. The positioning end is inclined toward the bottom of the power exchange platform 1, and the guiding end is inclined toward the bottom of the first protective door. A longitudinal beam 32 is provided at the bottom of the power exchange platform 1 along the width direction. The longitudinal beam 32 is located on both sides of the power exchange port 3. The longitudinal beam 32 of the power exchange platform 1 is rotatably connected to the second rotating wheel 27. When the positioning end is in the direction of the width, the longitudinal beam 32 is located on both sides of the power exchange port 3. When the end moves toward the middle of the power exchange port 3 together with the first protective door, when the positioning end moves to touch the second rotating wheel 27, the positioning end and the second rotating wheel 27 are in contact and connected, and the positioning end is limited along the moving direction of the first protective door; the first protective door continues to move toward the middle of the power exchange port 3 driven by the driving device 5, and the third connecting rod 2541 rotates counterclockwise at the connecting end, so that the first rotating wheel 2542 at the guide end is pushed against the bottom of the first protective door, so that the first protective door is lifted upward under the drive of the circular arc trajectory movement of the guide end, realizing the parallel movement of the first protective door so that the top surface of the first protective door remains flush with the top surface of the power exchange platform 1. Similarly, the second protective door moves relative to the first protective door, so that the top surface of the second protective door remains flush with the top surface of the power exchange platform 1.

[0138] In this scheme, if Fig.14 and Fig.15 As shown, the first connecting rod assembly 253 includes a first connecting rod 2531 and a second connecting rod 2532 hingedly connected between the door panel 30 and the protective door 4, so as to achieve stable support on both sides of the protective door 4 and enable the protective door 4 to move relative to the door panel 30 to a certain extent. The height distance between the protective door 4 and the door panel 30 is adjustable, thereby ensuring that the protective door 4 moves upward relative to the door panel 30, so that the protective door 4 is flush with the top surface of the power exchange platform 1; as shown Fig.15 As shown, the second connecting rod assembly 254 includes a V-shaped third connecting rod 2541, and one end of the third connecting rod 2541 is protruded downward and is arranged as a connecting end with the door panel 30, and the positioning end and the guide end are respectively extended upward at an angle, and the positioning end on one side can be positioned and kept in place, and the guide end on the other side can push against the bottom of the protective door 4, so that the guide end can push the protective door 4 upward, thereby realizing the upward movement of the protective door 4 until it is flush with the top surface of the battery exchange platform 1.

[0139] Specifically, Fig.17 As shown, the guide assembly 26 includes a lead screw 263 and a slide rail 264 connected to the battery exchange platform 1, and a slider 265 is movably connected to the lead screw 263 and slidably and fixedly connected to the slide rail 264; the slider 265 is connected to the bottom of the door panel 30, and the motor drives the lead screw 263 to rotate so that the slider 265 moves along the slide rail 264, driving the door panel 30 to move along the slide rail 264.

[0140] In this solution, the lead screw 263 and the slide rail 264 are respectively connected to a slider 265, and the slider 265 can move along the lead screw 263 and the slide rail 264 at the same time. The lead screw 263 is driven by a motor to drive the slider 265 to move along the lead screw 263, so that the slider 265 can move along the slide rail 264. The slider 265 is connected to the bottom of the door panel 30, and can drive the door panel 30 to translate along the slide rail 264, so as to realize the horizontal displacement of the door panel 30 and the protective door 4 along the power exchange platform 1; ensure the straight movement path of the protective door 4 and the door panel 30, and ensure that the protective door 4 and the door panel 30 always move in a straight line along the established route during the movement process without deviation.
