Description

Technical Field

[0001] The present invention relates to the field of battery replacement, and in particular to a channel opening and closing device and a battery replacement station comprising the same. Background Art

[0002] In the prior art, in order to effectively separate the battery swapping area of ​​the battery swapping equipment from the charging area inside the battery swapping station, a lifting door is usually set at the passageway of the battery swapping station. However, the current technology often uses manual control or a separate drive device to drive the lifting door, which is complex in structure and has some safety hazards and inconveniences.

[0003] For example, there are certain safety risks in manually controlling the lift door. Manual operation may lead to misoperation or improper operation. For example, the lift door fails to open and close in time when the battery swap equipment enters and exits, or the battery swap equipment does not fully enter the battery swap station before driving the lift door to close the passage, leading to a series of safety issues such as cross-traffic and collision accidents. The use of drive equipment to control the lift door makes the control system complex and costly, and additional sensors are required to detect the status of the lift door to avoid control failure. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art and provide a channel opening and closing device and a battery swap station including the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A passage opening and closing device, the passage opening and closing device comprising a passage opening for a battery swapping device to enter and exit a charging area and a lifting door capable of opening and closing the passage opening, the passage opening opening and closing device further comprising a counterweight, a first pulley block, a second pulley block and a door panel adjustment device, the lifting door and the counterweight being connected by a first pulley block, the weight of the counterweight being configured to be able to drive the lifting door to rise;

[0007] The door panel adjustment device and the counterweight are connected by a second pulley group. The door panel adjustment device is arranged on the travel path of the battery exchange equipment within the charging area by a flipping connection. When the battery exchange equipment moves onto the door panel adjustment device, the door panel adjustment device can drive the counterweight to rise through the second pulley group, so as to drive the lifting door to descend through the first pulley group.

[0008] In this technical solution, first, by reasonably setting the weight of the counterweight, the counterweight relationship between the counterweight and the lifting door is such that the counterweight drives the lifting door to rise, making the passage opening normally open, enabling the battery swapping device to pass through the passage opening smoothly. Moreover, setting the counterweight can also balance the gravity of the lifting door, improve the stability of the lifting door movement, ensure that the lifting door can maintain a stable and vertical state during movement, and at the same time reduce the driving burden on the door panel adjustment device, lower its load, thereby reducing the required driving force and saving energy. Secondly, by arranging the door panel adjustment device on the traveling path of the battery swapping device in the charging area, the force generated when the battery swapping device travels past the door panel adjustment device is transmitted to the counterweight via the second pulley group to drive the counterweight to rise, changing the counterweight relationship between the counterweight and the lifting door, causing the lifting door to descend and making the passage opening normally closed, so as to use the weight of the battery swapping device to achieve the purpose of driving the lifting door to descend and close the passage opening, enabling the passage opening to be self-controlled according to the traveling position of the battery swapping device. And since the descent of the lifting door is triggered by the contact between the battery swapping device and the door panel adjustment device, this structural design can provide a more convenient operation method for closing the passage opening of the battery swapping station. Without additionally setting a driving mechanism to drive the lifting door to close, the separation between the battery swapping area and the charging area of the battery swapping device is completed, improving the convenience of operation.

[0009] Preferably, the door panel adjustment device is arranged on the ground of the charging area of the battery swapping station and at least partially located within the equipment stop area where the battery swapping device exchanges battery packs with the palletizer.

[0010] In this technical solution, by arranging the door panel adjustment device on the charging area inside the battery swapping station, when the battery swapping device completely enters the charging area, the operation of the door panel adjustment device can be automatically started without additional manual intervention or external signal triggering. And this interaction form can also more precisely control the start and stop of the door panel adjustment device, avoiding the situation where when the battery swapping device has not completely entered the charging area, the battery swapping device acts on the door panel adjustment device and causes the lifting door to descend, resulting in damage to the battery swapping device due to the collision between the lifting door and the battery swapping device still partially located at the passage opening.

[0011] Preferably, the door panel adjustment device is arranged on the ground of the charging area of the battery swapping station and at one end away from the lifting door along the moving direction of the battery swapping device, and the door panel adjustment device can contact the front end of the battery swapping device along its traveling path.

[0012] In this technical solution, adopting this structural form, by making the front end of the battery swapping device contact the door panel adjustment device, it can respond more timely and drive the counterweight to move upward compared to other contact positions, thereby driving the lifting door to close the passage opening.

[0013] Preferably, the door panel adjustment device comprises:

[0014] A pressure plate, one end of which is connected to the chain of the second pulley block, and the other end of which is extended toward the charging area to contact the battery exchange device;

[0015] A bracket is arranged on the ground near the charging area, the pressing plate is arranged on the bracket through the second pulley block, and slide grooves extending along the moving direction of the pressing plate for the pressing plate to move are arranged on both sides of the bracket, and both sides of the connecting end of the pressing plate and the second pulley block are embedded in the slide grooves, a pulley of the second pulley block is arranged at one end of the bracket away from the ground, and another pulley of the second pulley block is arranged on the ground with a spacing from the bracket, and a through groove for the chain of the second pulley block to pass through is arranged on the bracket, and the extension direction of the through groove is the same as the extension direction of the slide groove;

[0016] Among them, one end of the chain of the second pulley group is connected to the pressure plate, and the other end is connected to the counterweight after passing through the pulley connected to the bracket and the pulley set on the ground in sequence. The pressure plate can be pressed by the power exchange equipment and move in the slide groove to drive the counterweight to move through the second pulley group and then drive the lifting door to move through the first pulley group to close the passage opening.

[0017] In the present technical solution, the closing effect of the lifting door on the passage opening is achieved through the synergistic effect of the pressure plate being pressed and the pressure plate moving in the slide groove to drive the second pulley group to drive the counterweight and then drive the lifting door to move through the first pulley group. When the pressure plate is pressed by the battery exchange equipment, the battery exchange equipment can use its own gravity to quickly trigger the door panel adjustment device without the need for other external forces. In addition, the use of this direct contact form also makes the operation of the door panel adjustment device more convenient and easy to operate.

[0018] Preferably, the passage opening and closing device also includes a displacement amplification mechanism, and the door panel adjustment device is transmission-connected to the second pulley group via the displacement amplification mechanism, and the displacement amplification mechanism is used to amplify the first displacement generated by the door panel adjustment device under the action of the power exchange device into a second displacement that drives the counterweight to rise.

[0019] In this technical solution, a displacement amplification mechanism is provided to amplify the amplitude of the displacement of the power swapping device driving the door panel adjustment device downward after the power swapping device travels to the door panel adjustment device, so that the first displacement of the actual downward movement of the door panel adjustment device is amplified into a second displacement that can drive the counterweight to rise and close the lifting door, increasing the amplitude of the door panel adjustment device driving the lifting door to rise and fall, and meeting the height requirement for the lifting and lowering of the lifting door. This structural setting provides flexibility and adaptability for applications that require a greater lifting height in some scenarios. The introduction of the displacement amplification mechanism allows for more flexible lifting and lowering adjustments of the door panel adjustment device, enabling customized control of the movement of the lifting door to meet the requirements of different needs and application scenarios, and making it easier to adapt to passage openings of different sizes and heights.

[0020] Preferably, the passage opening opening and closing device further includes a support frame body, the interior of the support frame body forms the charging area, both the counterweight and the displacement amplification mechanism are arranged on the side surface of the support frame body, and both the counterweight and the displacement amplification mechanism are located on the same side of the support frame body.

[0021] In this technical solution, the counterweight mechanism and the displacement amplification mechanism are arranged on the support frame body to utilize the existing structure to achieve the fixed installation of the counterweight mechanism, with a simple structure. At the same time, such an arrangement also avoids the interference of the counterweight mechanism and the displacement amplification mechanism to the movement of the power swapping device and the battery pack to be carried inside the charging area of the power swapping station, and avoids interfering with the normal conveying process of the battery pack.

[0022] Among them, the displacement amplification mechanism and the counterweight are arranged on the support frame body on the same side and connected by a second pulley group to form a system with a synergistic effect, which helps to achieve a more precise and stable movement of the counterweight in a coordinated manner, and further makes the movement of the lifting door more stable and vertical.

[0023] Preferably, the displacement amplification mechanism amplifies the first displacement into the second displacement by adopting a movable pulley group.

[0024] In this technical solution, the method of adopting a fixed pulley group, that is, adopting a plurality of movable pulleys, compared with other solutions that amplify the stroke through a lever structure, changes the movement path of the counterweight by changing the direction of force transmission, thereby changing the moving distance of the counterweight. Therefore, adopting this method can most directly and efficiently change the amplitude of the movement of the counterweight, and can make the space occupied by the entire displacement amplification mechanism relatively small.

[0025] Preferably, a support frame body is also provided inside the power swapping station, and the displacement amplification mechanism includes:

[0026] A bearing platform, which is connected to the door panel adjustment device through the chain of the second pulley group;

[0027] A plurality of pulleys, part of the pulleys are arranged at intervals in sequence on the bearing platform, and the other part of the pulleys are arranged at intervals in sequence on the support frame corresponding to the pulleys on the bearing platform. One end of the chain of the second pulley group is fixedly connected to the support frame, and the other end passes through a plurality of the pulleys in sequence and is connected to the counterweight.

[0028] In this technical solution, adopting this structural form fully realizes the amplification effect of chain drive. This enables the second pulley group, during transmission, to amplify the lifting amplitude of the counterweight, i.e., the lifting door, through the action of a plurality of pulleys, thereby enabling the lifting door to move within a larger range. At the same time, a plurality of pulleys in the displacement amplification mechanism are designed in a hierarchical structure, with part of them arranged on the bearing platform and the other part correspondingly arranged on the support frame. Such a design helps to maintain the balance and stability of the displacement amplification mechanism, prevent uneven force during movement, and improve the reliability of the amplification mechanism.

[0029] Preferably, the multiple pulleys arranged on the support frame and the multiple pulleys arranged on the bearing platform are cross - arranged.

[0030] In this technical solution, by cross - arranging the pulleys, the chain of the second pulley group can be evenly stressed during movement, which helps to reduce the lateral swing of the chain during movement, makes the movement of the displacement amplification mechanism more stable, and ensures the verticality and stability of the lifting door during movement.

[0031] Preferably, along the height direction of the support frame, the counterweight is arranged above the displacement amplification mechanism, and the height of the connection end of the counterweight to the support frame through the first pulley group is the same as the maximum height that the lifting door rises.

[0032] In this technical solution, setting the height of the counterweight to be the same as the maximum height that the lifting door rises helps to achieve vertical balance. Such a design can ensure that balance is maintained throughout the movement of the lifting door, prevent instability caused by insufficient or excessive counterweight height. The reasonable setting of the counterweight may bring better energy efficiency performance. By reducing the burden on the starting mechanism, less energy may be required to drive the movement of the lifting door, thereby reducing the energy consumption of the entire door panel adjustment device.

[0033] Preferably, on both sides of the lifting door along the moving direction of the power - swapping device, there are fixing members fixedly connected to the first pulley group, and the lifting door is connected to the first pulley group through the fixing members.

[0034] In this technical solution, the setting of the fixing member helps to enhance the stability of the lifting door during movement. By being fixedly arranged on both sides of the lifting door, it can effectively prevent the lifting door from swaying or deviating from the track during movement, and improve the balance of the lifting door during movement.

[0035] A battery swapping station, characterized in that it includes the channel opening and closing device described in any one of the above.

[0036] In this technical solution, the channel opening and closing device adopting the above structural form can effectively control the opening and closing of the channel in the battery swapping station, provide a flexible operation channel for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0037] The positive and progressive effects of the present invention are as follows:

[0038] 1. By reasonably setting the weight of the counterweight member in the channel opening and closing device, the counterweight relationship between the counterweight member and the lifting door is such that the counterweight member drives the lifting door to rise, making the channel opening in a normally open state, enabling the battery swapping equipment to pass through the channel smoothly. Moreover, setting the counterweight member can also balance the gravity of the lifting door, improve the stability of the lifting door during movement, ensure that the lifting door can maintain a stable and vertical state during movement, and at the same time reduce the driving burden on the door panel adjustment device, lower its load, thereby reducing the required driving force and saving energy.

[0039] 2. Secondly, by arranging the door panel adjustment device on the traveling path of the battery swapping equipment in the charging area, the force generated when the battery swapping equipment travels through the door panel adjustment device is transmitted to the counterweight member via the second pulley group to drive the counterweight member to rise, changing the counterweight relationship between the counterweight member and the lifting door, causing the lifting door to descend and making the channel opening in a normally closed state, so as to use the weight of the battery swapping equipment to achieve the purpose of driving the lifting door to descend to close the channel opening, enabling the channel opening to be self-controlled according to the traveling position of the battery swapping equipment.

[0040] 3. And, since the descent of the lifting door is triggered by the contact between the battery swapping equipment and the door panel adjustment device to activate its closing function, this structural design can provide a more convenient operation method for closing the channel opening of the battery swapping station. Without additionally setting a driving mechanism to drive the lifting door to close, the separation between the battery swapping area and the charging area of the battery swapping equipment is completed, improving the convenience of operation.

[0041] 4. The battery swapping station adopting the above structural form of the channel opening and closing device can effectively control the opening and closing of the channel in the battery swapping station, provide a flexible operation channel for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0081] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments thereby.

[0082] As Figures 1 - 15As shown, the present invention discloses a battery swap station 500, in which a channel opening and closing device 100 is provided. The channel opening and closing device 100 is used to close and open the channel. The switching between the open state and the closed state is as shown in FIG. Figure 1 and Figure 8 As shown, the passageway is set between the battery swap area 51 and the charging area 16 of the battery swap station 500. The passageway specifically refers to the area for the battery swap equipment 600 (i.e., the battery swap car) to travel back and forth between the battery swap area 51 and the charging area 16. By setting the passageway opening and closing device 100 to control the opening and closing of the passageway 11, the battery swap area 51 and the charging area 16 can be effectively separated, thereby improving the safety factor of the battery swap station 500. It should be clarified in the specification that the battery swap area 51 of the battery swap station 500 in this embodiment is an open form with an open top. Under other feasible battery swap station 500 schemes, the battery swap area 51 is also a closed structure that can be surrounded by a box.

[0083] Among them, Figure 1 and Figure 2 As shown, the passage opening and closing device 100 specifically includes a lifting door 12 capable of opening and closing the passage opening 11 , a counterweight 200 , a first pulley block 14 , a second pulley block 15 and a door panel adjustment device 300 .

[0084] The lifting door 12 is arranged on the mounting door frames 13 on both sides of the passage opening 11, and the lifting door 12 is connected to the counterweight 200 through the first pulley block 14. The weight of the counterweight 200 is configured to drive the lifting door 12 to rise. At the same time, the counterweight 200 is connected to the door panel adjustment device 300 through the second pulley block 15. For details, please refer to Figure 7 and Figure 15 Therefore, in this solution, by controlling the weight of the counterweight 200, the lifting door 12 is in an open state when no other external force is applied, that is, the passage 1 is in a normally open state.

[0085] Furthermore, the door panel adjustment device 300 is disposed on the path of the battery-exchanging device 600 in the charging area 16 by means of a flip connection. When the battery-exchanging device 600 moves onto the door panel adjustment device 300, the door panel adjustment device 300 can drive the counterweight 200 to rise through the second pulley set 15, so as to drive the lifting door 12 to descend through the first pulley set 14. In other words, after the battery-exchanging device 600 passes through the door panel adjustment device 300, the weight of the battery-exchanging device 600 is applied to the door panel adjustment device 300, and the force can be transmitted to the counterweight 200 to change the normally open state of the passage opening 11, so that the lifting door 12 switches to the closed passage opening 11 in response to the force applied by the battery-exchanging device 600 to the door panel adjustment device 300.

[0086] Specifically, in this solution, the lifting door 12 located at the access opening 11 of the battery swapping station 500 is always in the normally open state under the action of the counterweight 200. When the battery swapping device 600 is on its travel path and enters the charging area 16 inside the battery swapping station 500 along its moving direction X through the access opening 11, the battery swapping device 600 starts the door panel adjusting device 300 by contacting the door panel adjusting device 300 and drives the counterweight 200 to move through the second pulley group 15. Specifically, it drives the counterweight 200 to rise along the height direction. At the same time, the rise of the counterweight 200 will drive the first pulley group 14 to drive the lifting door 12 to descend in the height direction through its transmission connection with the lifting door 12, so that the lifting door 12 gradually closes the access opening 11, so as to effectively isolate the battery swapping area 51 of the battery swapping device 600 from the charging area 16 inside the battery swapping station 500.

[0087] In this embodiment, first, by reasonably setting the weight of the counterweight 200, the counterweight relationship between the counterweight 200 and the lifting door 12 is such that the counterweight 200 drives the lifting door 12 to rise, making the access opening 11 in the normally open state, enabling the battery swapping device 600 to smoothly pass through the access opening 11. And setting the counterweight 200 can also balance the gravity of the lifting door 12, improve the stability of the movement of the lifting door 12, ensure that the lifting door 12 can maintain a stable and vertical state during movement, and at the same time can reduce the driving burden of the door panel adjusting device 300, reduce its load, thereby reducing the required driving force and saving energy.

[0088] Secondly, by arranging the door panel adjusting device 300 on the travel path of the battery swapping device 600 in the charging area 16, the force of the battery swapping device 600 passing by the door panel adjusting device 300 is transmitted to the counterweight 200 via the second pulley group 15 to drive the counterweight 200 to rise, changing the counterweight relationship between the counterweight 200 and the lifting door 12, so that the lifting door 12 descends and the access opening 11 is in the normally closed state, so as to use the weight of the battery swapping device 600 to drive the lifting door 12 to descend to close the access opening 11, enabling the access opening 11 to be self-controlled according to the travel position of the battery swapping device 600.

[0089] Moreover, since the descent of the lifting door 12 is triggered by the contact between the battery swapping device 600 and the door panel adjusting device 300 to trigger its closing function, this structural design solution can provide a more convenient operation method for closing the access opening 11 of the battery swapping station 500. Without additionally setting a driving mechanism to drive the lifting door 12 to close, the separation between the battery swapping area 51 of the battery swapping device 600 and the charging area 16 is completed, improving the convenience of operation.

[0090] Preferably, as Figure 2 and Figure 9As shown, the door panel adjustment device 300 should be arranged on the ground of the charging area 16 of the battery swapping station 500, and at least partially located within the equipment stop area where the battery swapping device 600 and the palletizer transfer the battery pack.

[0091] In this embodiment, by arranging the door panel adjustment device 300 on the charging area 16 inside the battery swapping station 500, when the battery swapping device 600 fully enters the charging area 16, the operation of the door panel adjustment device 300 can be automatically started without additional manual intervention or external signal triggering. Only through the contact between the door panel adjustment device 300 and the battery swapping device 600 can the driving function of the door panel adjustment device 300 for the lifting door 12 be started. And this interaction form can also more precisely control the start and stop of the door panel adjustment device 300, avoiding the situation where when the battery swapping device 600 has not fully entered the charging area 16, the battery swapping device 600 acts on the door panel adjustment device 300, causing the lifting door 12 to descend, and resulting in the collision between the lifting door 12 and the battery swapping device 600 still partially located at the channel entrance 11, thus damaging the battery swapping device 600.

[0092] More preferably, as Figure 2 and Figure 9 shown, the door panel adjustment device 300 should further be arranged at one end along the moving direction X of the battery swapping device 600 away from the lifting door 12, and the door panel adjustment device 300 can contact the front end of the battery swapping device 600 along its traveling path. When the door panel adjustment device 300 is arranged at this position, the battery swapping device 600 just contacts the door panel adjustment device 300 in a parked state and applies a downward pressure to the door panel adjustment device 300, so that the door panel adjustment device 300 can be stably triggered. Therefore, it can respond and drive the counterweight 200 to move upward more timely compared to other contact positions, and then drive the lifting door 12 to close the channel entrance 11.

[0093] As Figure 4 and Figure 11 shown, this embodiment further provides a preferred structural setting scheme for the door panel adjustment device 300, which specifically includes a pressing plate 31 and a bracket 32.

[0094] Specifically, one end of the pressing plate 31 is connected to the chain of the second pulley group 15, and the other end of the pressing plate 31 extends towards the charging area 16 to contact the battery swapping device 600, that is, it is pressed by the battery swapping device 600. Therefore, in this embodiment, the pressing plate 31 is similar to a touch switch. After the battery swapping device 600 presses on the pressing plate 31, the movement of the lifting door 12 is realized through the transmission of the first pulley group 14 and the second pulley group 15.

[0095] Moreover, the bracket 32 is disposed on the ground near the charging area 16. The pressing plate 31 is hung on the bracket 32 by a chain in the second pulley set 15. Chutes 321 extending along the moving direction X of the pressing plate 31 are provided on the left and right sides of the bracket 32 for the pressing plate 31 to move. Both sides of the connection end of the pressing plate 31 and the second pulley set 15 are embedded in the chutes 321. Then, the pressing plate 31 presents a "seesaw" form relative to the bracket 32. One end of the pressing plate 31 is lifted by the chain, and the other end extends toward the charging area 16 and also faces the ground.

[0096] Meanwhile, a pulley of the second pulley set 15 is provided at one end of the bracket 32 away from the ground, and this pulley is used to lift the pressing plate 31. Another pulley of the second pulley set 15 is spaced from the bracket 32 on the ground, and this other pulley is vertically opposite to the pulley at the top of the bracket 32. A through groove 322 for the chain of the second pulley set 15 to pass through is provided on the bracket 32, and the extending direction of the through groove 322 is the same as the extending direction of the chutes 321.

[0097] In addition, the door panel adjusting device 300 further includes a base 33 disposed on the ground, and the bracket 32 and the other pulley spaced from it are both disposed on the base 33.

[0098] One end of the chain of the second pulley set 15 is connected to the pressing plate 31, and the other end passes through the pulley at the top of the bracket 32, the through groove 322, and the other pulley spaced from the bracket 32 on the base 33 in sequence and is then connected to the counterweight 200. The pressing plate 31 can be pressed by the power exchange device 600 and move in the chutes 321 to drive the counterweight 200 to move through the second pulley set 15, and then drive the lifting door 12 to move through the first pulley set 14 to close the passage opening 11.

[0099] In this embodiment, through the synergistic effect that the pressing plate 31 is pressed and the pressing plate 31 moves in the chutes 321 to drive the second pulley set 15 to drive the counterweight 200, and then drive the lifting door 12 to move through the first pulley set 14, the closing effect of the lifting door 12 on the passage opening 11 is realized. When the pressing plate 31 is pressed down by the power exchange device 600, it can be quickly triggered by using the relatively heavy self-gravity of the power exchange device 600 without borrowing other external forces. Moreover, adopting this form of direct contact also makes the operation of the door panel adjusting device 300 more stable and reliable.

[0100] Therefore, in this embodiment, as Figure 4 shown, when the power exchange device 600 does not enter the charging area 16 inside the power exchange station 500, the connection end of the pressing plate 31 and the second pulley set 15 is at the topmost position of the chutes 321 along the vertical direction, and the other end of the pressing plate 31 is in a state close to the ground, so that the lifting door 12 is in an "open state" relative to the passage opening 11.

[0101] As Figure 11 shown, when the power replacement device 600 fully enters the charging area 16 and contacts the door panel adjustment device 300, that is, after pressing the pressure plate 31 by the gravity of the power replacement device 600 itself, the connection end of the pressure plate 31 and the second pulley group 15 is at the bottommost position of the chute 321 along the vertical direction, making the pressure plate 31 present a "parallel" state to the ground, that is, the pressure plate 31 will be pressed by the power replacement device 600 and be at the bottom of the power replacement device 600, located between the power replacement device 600 and the ground. At the same time, through the transmission connection between the pressure plate 31 and the second pulley group 15, the counterweight 200 is driven to rise, and then through the transmission connection between the counterweight 200 and the lifting door 12 by the first pulley group 14, the lifting door 12 is driven to descend so that the passage opening 11 is closed. For details, reference can be made to Figure 7 and Figure 15 the simplified diagrams shown therein.

[0102] As Figures 2 - 3 , Figure 5 , Figures 9 - 10 and Figure 12 shown, the passage opening opening and closing device 100 further includes a displacement amplification mechanism 400. The door panel adjustment device 300 is in transmission connection with the second pulley group 15 through the displacement amplification mechanism 400. The displacement amplification mechanism 400 is used to amplify the first displacement generated by the door panel adjustment device 300 under the action of the power replacement device 600 into a second displacement for driving the counterweight 200 to rise. For details, reference can be made to Figure 7 and Figure 15 the simplified diagrams shown therein.

[0103] In this embodiment, by setting the displacement amplification mechanism 400, the amplitude of the downward movement of the door panel adjustment device 300 driven by the power replacement device 600 after the power replacement device 600 travels to the door panel adjustment device 300 is amplified, so that the first displacement of the actual downward movement of the door panel adjustment device 300 is amplified into a second displacement that can drive the counterweight 200 to rise to close the passage opening 11 of the lifting door 12, increasing the amplitude of the lifting and lowering of the door panel adjustment device 300 driving the lifting door 12 and meeting the height requirement of the lifting and lowering of the lifting door 12. This structural setting scheme provides flexibility and adaptability for applications that require a greater lifting height in some scenarios. The introduction of the displacement amplification mechanism 400 allows the door panel adjustment device 300 to perform more flexible lifting and lowering adjustments, enabling customized control of the movement of the lifting door 12 to meet the requirements of different needs and application scenarios and making it easier to adapt to passage openings 11 of different sizes and heights.

[0104] Specifically, as Figure 2 and Figure 9As shown in the figure, the channel opening and closing device 100 further includes a support frame body 17 arranged inside the battery swapping station 500, and a charging area 16 is formed inside the support frame body 17. Among them, in this embodiment, both the counterweight 200 and the displacement amplification mechanism 400 are arranged on the support frame body 17 and are both located on the side surface of the support frame body 17. Preferably, both the counterweight 200 and the displacement amplification mechanism 400 are located on the same side of the support frame body 17.

[0105] In this embodiment, the counterweight mechanism and the displacement amplification mechanism 400 are arranged on the support frame body 17 to utilize the existing structure to realize the fixed installation of the counterweight mechanism, and the structure is simple. At the same time, such an arrangement also avoids the interference of the counterweight mechanism and the displacement amplification mechanism 400 to the movement of the battery swapping device 600 and the battery pack to be carried inside the charging area 16 of the battery swapping station 500, and avoids interfering with the normal conveying process of the battery pack.

[0106] Among them, the displacement amplification mechanism 400 and the counterweight 200 are arranged on the support frame body 17 on the same side and are connected by the second pulley group 15 to form a system with a synergistic effect, which helps to realize the more precise and stable movement of the counterweight 200 in a coordinated manner, and further makes the movement of the lifting door 12 more stable and vertical.

[0107] Specifically, the door panel adjustment device 300 is arranged on the ground of the charging area 16 near the two support frame bodies 17, preferably at the middle position of the traveling path of the battery swapping device 600. A plurality of pulleys of the first pulley group 14 are provided at the bottom end of the support frame body 17 to realize the transmission connection between the door panel adjustment device 300 and the displacement amplification mechanism 400. Moreover, a plurality of pulleys of the first pulley group 14 and a plurality of pulleys of the second pulley group 15 are also provided at one end of the support frame body 17 close to the counterweight 200 and far from the displacement amplification mechanism 400 to realize the transmission connection between the counterweight 200 and the displacement amplification mechanism 400 and the transmission connection between the counterweight 200 and the lifting door 12.

[0108] In other embodiments, the counterweight 200 and the displacement amplification mechanism 400 can also be arranged on the support frame bodies 17 on both sides of the moving direction X of the battery swapping device 600, that is, the counterweight 200 and the displacement amplification mechanism 400 are arranged on each side of the support frame body 17 to change the lifting of the lifting door 12 through dual actions, and can also balance the acting force of the counterweight 200 driving the lifting door 12 to move.

[0109] Preferably, as Figure 5 and Figure 12As shown, in this embodiment, the displacement amplification mechanism 400 amplifies the first displacement into the second displacement by using a movable pulley block. The way of using a fixed pulley block, that is, using multiple movable pulleys, compared with other solutions that amplify the stroke through a lever structure, affects the movement path of the counterweight 200 by changing the force transmission direction, thereby changing the moving distance of the counterweight 200. Therefore, using this method can most directly and efficiently change the amplitude of the movement of the counterweight 200, and can make the space occupied by the entire displacement amplification mechanism 400 relatively small.

[0110] Furthermore, the displacement amplification mechanism 400 includes a bearing platform 41 and several pulleys.

[0111] Specifically, the bearing platform 41 is connected to the door panel adjustment device 300 through the chain of the second pulley block 15. A part of the pulleys are arranged at intervals on the bearing platform 41 in sequence. This part of the pulleys are movable pulleys. Another part of the pulleys are arranged at intervals on the support frame 17 corresponding to the pulleys on the bearing platform 41 in sequence. This part of the pulleys are fixed pulleys. And one end of the chain of the second pulley block 15 is fixedly connected to the support frame 17, and the other end passes through several pulleys in sequence and is connected to the counterweight 200. In this way, it can be realized that the first displacement of the movement of the door panel adjustment device 300 is amplified into the second displacement of the movement of the counterweight 200 by the way of connecting the movable pulley and the fixed pulley in series and using the movable pulley to increase the moving displacement.

[0112] In this embodiment, adopting this structural form fully realizes the amplification effect of chain drive. When the second pulley block 15 is driving, it can make the lifting amplitude of the counterweight 200, that is, the lifting amplitude of the lifting door 12, be amplified through the action of several pulleys, so as to realize the movement of the lifting door 12 within a larger range. At the same time, several pulleys in the displacement amplification mechanism 400 are designed in a hierarchical structure. One part is arranged on the bearing platform 41, and the other part is correspondingly arranged on the support frame 17. Such a design helps to maintain the balance and stability of the displacement amplification mechanism 400, prevent uneven force during the movement process, and improve the reliability of the amplification mechanism.

[0113] More preferably, the multiple pulleys arranged on the support frame 17 and the multiple pulleys arranged on the bearing platform 41 are arranged in a cross pattern. By arranging the pulleys in a cross pattern, the chain of the second pulley block 15 can be evenly stressed during movement, which helps to reduce the lateral swing of the chain during movement, makes the movement of the displacement amplification mechanism 400 more stable, and ensures the verticality and stability of the movement of the lifting door 12.

[0114] In addition, as Figure 3 、 Figure 10 and Figure 12As shown, along the height direction of the support frame 17, the counterweight 200 is arranged above the displacement amplification mechanism 400, and the height of the connection end of the counterweight 200 through the first pulley group 14 and the support frame 17 is the same as the maximum height that the lifting door 12 rises to.

[0115] In this embodiment, the height setting of the counterweight 200 is the same as the maximum height that the lifting door 12 rises to, which helps to achieve vertical balance. Such a design can ensure that the balance is maintained throughout the movement of the lifting door 12, preventing unstable situations caused by insufficient or excessive counterweight height. The reasonable setting of the counterweight 200 may bring better energy efficiency performance. By reducing the burden on the starting mechanism, less energy may be required to drive the movement of the lifting door 12, thereby reducing the energy consumption of the entire door panel adjustment device 300.

[0116] As Figure 13 and Figure 14 shown, on both sides of the lifting door 12 along the moving direction X of the battery swapping device 600, there are fixing members 121 fixedly connected to the first pulley group 14, and the lifting door 12 is connected to the first pulley group 14 through the fixing members 121. Preferably, the number of the fixing members 121 is multiple, and they are arranged in pairs on both sides of the lifting door 12 to be in transmission connection with the first pulley group 14.

[0117] And at the position of the installation door frame 13 corresponding to the fixing member 121, there is a slide rail 131 adapted to the fixing member 121 to provide a guide for the movement of the lifting door 12 and enable the movement of the lifting door 12.

[0118] In this technical solution, the setting of the fixing member 121 helps to enhance the stability of the movement of the lifting door 12. By being fixedly arranged on both sides of the lifting door 12, it can effectively prevent the lifting door 12 from swaying or deviating from the track during the movement process, and improve the balance of the movement of the lifting door 12.

[0119] As Figure 1 and Figure 8 shown, a battery swapping station 500 is also disclosed. The battery swapping station 500 adopts the above-mentioned channel opening and closing device 100, and the channel opening and closing device 100 is arranged inside the battery swapping station 500 to realize the opening and closing of the channel opening 11 in the battery swapping station 500.

[0120] In this embodiment, the channel opening and closing device 100 adopting the above structural form can effectively control the opening and closing of the channel opening 11 in the battery swapping station 500, provide a flexible operation channel for the battery swapping device 600, and realize safe and orderly battery replacement services.

Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
