Description

Technical Field

[0001] The utility model relates to the field of power exchange, and in particular to a channel opening and closing device and a power exchange 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. Utility Model Content

[0004] The technical problem to be solved by the utility model 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 utility model 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 the present technical solution, firstly, 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, so that the passage opening is in a normally open state, so that the battery exchange equipment can pass through the passage opening smoothly, and the counterweight can also balance the gravity of the lifting door, improve the stability of the lifting door movement, and ensure that the lifting door can maintain a stable and vertical state during movement, and at the same time, it can also reduce the driving burden of the door panel adjustment device and reduce its load, thereby reducing the required driving force and saving energy. Secondly, by setting the door panel adjustment device on the travel path of the battery exchange equipment in the charging area, the force of the battery exchange equipment passing through the door panel adjustment device is transmitted to the counterweight through the second pulley group to drive the counterweight to rise, and the counterweight relationship between the counterweight and the lifting door is changed, so that the lifting door descends and the passage opening is in a normally closed state, so as to use the weight of the battery exchange equipment to achieve the purpose of driving the lifting door to descend to close the passage opening, so that the passage opening can be controlled automatically according to the driving position of the battery exchange equipment. Moreover, since the descent of the lifting door is triggered by the contact between the battery swapping equipment and the door panel adjustment device to trigger its closing function, this structural design scheme can provide a more convenient operation method for closing the passage entrance of the battery swapping station. There is no need to set up an additional driving mechanism to drive the lifting door to close, thereby completing the separation of the battery swapping area and the charging area of ​​the battery swapping equipment, thereby improving the convenience of operation.

[0009] Preferably, the door panel adjustment device is arranged on the ground of the charging area of ​​the battery swap station, and is at least partially located in the equipment stop area where the battery swap equipment and the palletizer hand over the battery pack.

[0010] In the present technical solution, by arranging the door panel adjustment device on the charging area inside the battery swap station, when the battery swap equipment fully enters the charging area, the door panel adjustment device can be automatically started without additional human intervention or external signal triggering, and this interactive form can also more accurately control the start and stop of the door panel adjustment device, to avoid the battery swap equipment acting on the door panel adjustment device and causing the lifting door to drop when the battery swap equipment has not fully entered the charging area, causing the lifting door to collide with the battery swap equipment that is still partially located at the passage entrance, thereby causing damage to the battery swap equipment.

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

[0012] In the present technical solution, this structural form is adopted to make the front end of the battery exchange equipment contact the door panel adjustment device, so that it can respond more promptly than other contact positions and drive the counterweight to move upward, 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 the present technical solution, a displacement amplification mechanism is provided to amplify the amplitude of the downward movement of the door panel adjustment device after the battery exchange equipment travels to the door panel adjustment device, so that the first displacement of the door panel adjustment device actually moving downward is amplified to a second displacement that can satisfy the need to drive the counterweight to rise and close the lifting door, thereby increasing the amplitude of the lifting and lowering of the lifting door by the door panel adjustment device to meet the height requirements for the lifting and lowering of the lifting door. 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 allows the door panel adjustment device to perform more flexible lifting and lowering adjustments, and can achieve customized control of the movement of the lifting door to meet the requirements of different needs and application scenarios, and is more easily adapted to passage openings of different sizes and heights.

[0020] Preferably, the channel opening and closing device also includes a supporting frame, the interior of the supporting frame forms the charging area, the counterweight and the displacement amplification mechanism are both arranged on the side of the supporting frame, and the counterweight and the displacement amplification mechanism are both located on the same side of the supporting frame.

[0021] In this technical solution, the counterweight mechanism and the displacement amplification mechanism are arranged on the support frame, so as 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 prevents the counterweight mechanism and the displacement amplification mechanism from interfering with the movement of the battery swapping equipment and the battery pack to be carried within the charging area of ​​the battery swapping station, and avoids interfering with the normal transportation process of the battery pack.

[0022] Among them, the displacement amplification mechanism and the counterweight are arranged on the support frame on the same side and connected by a second pulley set to form a synergistic system, which helps to achieve more precise and smooth movement of the counterweight through mutual coordination, thereby making the movement of the lifting door smoother and more vertical.

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

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

[0025] Preferably, a support frame is further provided inside the battery swap station, and the displacement amplification mechanism comprises:

[0026] A bearing platform connected to the door panel adjusting device via a chain of the second pulley block;

[0027] A plurality of pulleys, some of which are arranged at intervals in sequence on the bearing platform, and another portion of the pulleys are arranged at intervals in sequence on the supporting frame corresponding to the pulleys on the bearing platform; one end of the chain of the second pulley group is fixedly connected to the supporting frame, and the other end is connected to the counterweight after passing through a plurality of the pulleys in sequence.

[0028] In the technical solution, this structural form is adopted to fully realize the amplification effect of the chain transmission, so that when the second pulley group is transmitting, the counterweight can magnify the lifting range of the lifting door through the action of several pulleys, thereby realizing the movement of the lifting door in a larger range. At the same time, the several pulleys in the displacement amplification mechanism adopt a graded design structure, one part is set on the bearing platform, and the other part is correspondingly set 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 plurality of pulleys arranged on the support frame and the plurality of pulleys arranged on the bearing platform are arranged crosswise.

[0030] In this technical solution, by cross-setting 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, making the movement of the displacement amplification mechanism more stable and ensuring 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 connecting end of the counterweight through the first pulley block and the support frame is the same as the maximum height of the lifting door.

[0032] In the present technical solution, the height of the counterweight is set to be the same as the maximum height of the lift door, which helps to achieve vertical balance. Such a design can ensure that the balance is maintained throughout the entire movement of the lift door, and prevent instability caused by insufficient or excessive counterweight height. 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 lift door to move, thereby reducing the energy consumption of the entire door panel adjustment device.

[0033] Preferably, fixing members fixedly connected to the first pulley block are provided on both sides of the lifting door along the moving direction of the battery exchange device, and the lifting door is connected to the first pulley block via the fixing members.

[0034] In the present technical solution, the setting of the fixing parts helps to enhance the stability of the movement of the lifting door. By being fixed on both sides of the lifting door, it can effectively prevent the lifting door from swaying or deviating from the track during movement, thereby improving the balance of the movement of the lifting door.

[0035] A battery swap station, characterized in that it comprises the channel opening and closing device as described in any one of the above items.

[0036] In the present technical solution, the channel opening and closing device using the above-mentioned structural form can effectively control the opening and closing of the channel opening in the battery swap station, provide a flexible operating channel for the battery swap equipment, and realize safe and orderly battery replacement services.

[0037] The positive and progressive effects of the utility model are:

[0038] 1. The passage opening and closing device reasonably sets the weight of the counterweight so that the counterweight relationship between the counterweight and the lifting door is such that the counterweight drives the lifting door to rise, so that the passage opening is in a normally open state, allowing the battery exchange equipment to pass through the passage opening smoothly. The setting of the counterweight can also balance the gravity of the lifting door, improve the stability of the movement of the lifting door, and ensure that the lifting door can maintain a stable and vertical state during movement. At the same time, it can also reduce the driving burden of the door panel adjustment device and reduce its load, thereby reducing the required driving force and saving energy.

[0039] 2. Secondly, by setting the door panel adjustment device on the travel path of the battery swapping equipment in the charging area, the force of the battery swapping equipment passing through the door panel adjustment device is transmitted to the counterweight via the second pulley group to drive the counterweight to rise, thereby changing the counterweight relationship between the counterweight and the lifting door, so that the lifting door is lowered and the passage opening is in a normally closed state, so as to utilize the weight of the battery swapping equipment to drive the lifting door to descend to close the passage opening, so that the passage opening can be controlled by itself according to the driving position of the battery swapping equipment.

[0040] 3. Moreover, since the descent of the lifting door is triggered by the contact between the battery swapping equipment and the door panel adjustment device to trigger its closing function, this structural design scheme can provide a more convenient operation method for closing the passage entrance of the battery swapping station. There is no need to set up an additional driving mechanism to drive the lifting door to close, thereby completing the separation of the battery swapping area and the charging area of ​​the battery swapping equipment, thereby improving the convenience of operation.

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

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

[0082] like Figure 1-Figure 15As shown, the utility model discloses a battery swap station 500, in which a channel opening and closing device 100 is arranged. 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 set 14 , a second pulley set 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 Fig.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 passage opening 11 of the battery swap station 500 is always in a normally open state under the action of the counterweight 200. When the battery swap equipment 600 is on its travel path and passes through the passage opening 11 along its moving direction X to enter the charging area 16 inside the battery swap station 500, the battery swap equipment 600 starts the door panel adjustment device 300 by contacting the door panel adjustment device 300 and drives the counterweight 200 to move through the second pulley group 15, specifically driving the counterweight 200 to rise in the height direction. At the same time, the rise of the counterweight 200 will be connected to the lifting door 12 through the transmission connection, driving the first pulley group 14 to drive the lifting door 12 to descend in the height direction so that the lifting door 12 gradually closes the passage opening 11, so as to achieve effective isolation between the battery swap area 51 of the battery swap equipment 600 and the charging area 16 inside the battery swap station 500.

[0087] In this embodiment, firstly, 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, so that the passage opening 11 is in a normally open state, so that the battery exchange equipment 600 can smoothly pass through the passage opening 11, and the setting of the counterweight 200 can also balance the gravity of the lifting door 12, improve the stability of the movement of the lifting door 12, and ensure that the lifting door 12 can maintain a stable and vertical state during movement. At the same time, it can also reduce the driving burden of the door panel adjustment device 300 and reduce its load, thereby reducing the required driving force and saving energy.

[0088] Secondly, by setting the door panel adjustment device 300 on the travel path of the battery exchange equipment 600 in the charging area 16, the force of the battery exchange equipment 600 passing through the door panel adjustment device 300 is transmitted to the counterweight 200 via the second pulley group 15 to drive the counterweight 200 to rise, thereby changing the counterweight relationship between the counterweight 200 and the lifting door 12, so that the lifting door 12 descends and the passage opening 11 is in a normally closed state, so as to utilize the weight of the battery exchange equipment 600 to drive the lifting door 12 to descend to close the passage opening 11, so that the passage opening 11 can be controlled by itself according to the driving position of the battery exchange equipment 600.

[0089] Furthermore, since the descent of the lifting door 12 is triggered by the contact between the battery exchange equipment 600 and the door panel adjustment device 300 to trigger its closing function, this structural design scheme can provide a more convenient operation method for closing the passage opening 11 of the battery exchange station 500. There is no need to additionally set up a driving mechanism to drive the lifting door 12 to close, thereby completing the separation of the battery exchange area 51 and the charging area 16 of the battery exchange equipment 600, thereby improving the convenience of operation.

[0090] Preferably, if Figure 2 and Fig. 9As shown, the door panel adjustment device 300 should be set on the ground of the charging area 16 of the battery swap station 500, and at least partially located in the equipment stop area where the battery swap equipment 600 and the palletizer hand over the battery pack.

[0091] In this embodiment, the door panel adjustment device 300 is arranged on the charging area 16 inside the battery swap station 500, so that when the battery swap equipment 600 fully enters the charging area 16, the operation of the door panel adjustment device 300 can be automatically started without additional human intervention or external signal triggering. The driving function of the door panel adjustment device 300 on the lifting door 12 can be started only through the contact between the door panel adjustment device 300 and the battery swap equipment 600, and this form of interaction can also more accurately control the start and stop of the door panel adjustment device 300, to avoid the battery swap equipment 600 acting on the door panel adjustment device 300 to cause the lifting door 12 to drop when the battery swap equipment 600 has not fully entered the charging area 16, so that the lifting door 12 collides with the battery swap equipment 600 that is still partially located at the passage opening 11, thereby causing damage to the battery swap equipment 600.

[0092] More preferably, if Figure 2 and Fig. 9 As shown, the door panel adjustment device 300 should be further arranged at one end away from the lifting door 12 along the moving direction X of the power exchange device 600, and the door panel adjustment device 300 can contact the front end of the power exchange device 600 along its travel path. When the door panel adjustment device 300 is arranged at this position, the power exchange device 600 just contacts the door panel adjustment device 300 when it is parked, and applies downward pressure to the door panel adjustment device 300, so that the door panel adjustment device 300 can be stably triggered, so that it can respond more promptly than other contact positions and drive the counterweight 200 to move upward, thereby driving the lifting door 12 to close the passage opening 11.

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

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

[0095] In addition, the bracket 32 ​​is set on the ground near the charging area 16, and the pressure plate 31 is suspended on the bracket 32 ​​by the chain in the second pulley group 15, and a slide groove 321 extending along the moving direction X of the pressure plate 31 for the movement of the pressure plate 31 is provided on the left and right sides of the bracket 32, and the two sides of the connection end of the pressure plate 31 and the second pulley group 15 are embedded in the slide groove 321, so that the pressure plate 31 presents a "seesaw" form relative to the bracket 32, one end of the pressure plate 31 is suspended by the chain, and the other end extends toward the charging area 16 and is also set toward the ground.

[0096] At the same time, a pulley of the second pulley group 15 is provided at the end of the bracket 32 ​​away from the ground, and the pulley is used to lift the pressure plate 31, as well as another pulley of the second pulley group 15 arranged on the ground at a distance from the bracket 32. The other pulley and the pulley at the top of the bracket 32 ​​are arranged opposite to each other in the vertical height, and a through groove 322 is provided on the bracket 32 ​​for the chain of the second pulley group 15 to pass through, and the extension direction of the through groove 322 is the same as the extension direction of the slide groove 321.

[0097] In addition, the door panel adjustment device 300 further includes a base 33 disposed on the ground, and the bracket 32 ​​and another pulley spaced apart therefrom are both disposed on the base 33 .

[0098] One end of the chain of the second pulley group 15 is connected to the pressure plate 31, and the other end passes through the pulley at the top of the bracket 32, the through groove 322 and another pulley arranged on the base 33 at an interval from the bracket 32 ​​in sequence, and then is connected to the counterweight 200. The pressure plate 31 can be pressed by the battery exchange equipment 600 and move in the slide groove 321 to drive the counterweight 200 to move through the second pulley group 15 and then drive the lifting door 12 to move through the first pulley group 14 to close the passage opening 11.

[0099] In this embodiment, the closing effect of the lifting door 12 on the passage opening 11 is achieved through the synergistic effect of the pressure plate 31 being pressed and the pressure plate 31 moving in the slide groove 321 to drive the second pulley group 15 to drive the counterweight 200 and then driving the lifting door 12 to move through the first pulley group 14. When the pressure plate 31 is pressed down by the battery exchange device 600, the relatively heavy gravity of the battery exchange device 600 can be used to achieve rapid triggering 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 300 more stable and reliable.

[0100] Therefore, in this embodiment, if Figure 4 As shown, when the battery exchange equipment 600 has not entered the charging area 16 inside the battery exchange station 500, the connection end of the pressure plate 31 and the second pulley group 15 is at the top of the slide groove 321 along the vertical direction, and the other end of the pressure plate 31 is close to the ground, so that the lifting door 12 is in a "normally open state" relative to the passage opening 11.

[0101] like Fig.11 As shown, after the battery swap device 600 completely enters the charging area 16, it contacts the door panel adjustment device 300, that is, after the pressure plate 31 is pressed by the gravity of the battery swap device 600 itself, the connection end of the pressure plate 31 and the second pulley group 15 is at the bottom of the slide groove 321 along the vertical direction, so that the pressure plate 31 is in a "parallel" state to the ground, that is, the pressure plate 31 will be pressed by the battery swap device 600 and is at the bottom of the battery swap device 600, located between the battery swap device 600 and the ground, and at the same time, the counterweight 200 is driven to rise through the transmission connection between the pressure plate 31 and the second pulley group 15, and then the counterweight 200 and the lifting door 12 are driven to descend through the transmission connection between the first pulley group 14 so that the passage opening 11 is closed. For details, please refer to Figure 7 and Fig.15 The simplified diagram shown in .

[0102] like Figure 2-Figure 3 , Figure 5 , Figure 9-10 as well as Fig.12 As shown, the passage opening and closing device 100 also includes a displacement amplification mechanism 400, and the door panel adjustment device 300 is connected to the second pulley group 15 through the displacement amplification mechanism 400. The displacement amplification mechanism 400 is used to amplify the first displacement of the door panel adjustment device 300 under the action of the power exchange device 600 into a second displacement that drives the counterweight 200 to rise. For details, please refer to Figure 7 and Fig.15 The schematic shown.

[0103] In this embodiment, a displacement amplification mechanism 400 is provided to amplify the amplitude of the downward movement of the door panel adjustment device 300 after the battery exchange device 600 moves to the door panel adjustment device 300, so that the first displacement of the door panel adjustment device 300 actually moving downward is amplified to a second displacement that can drive the counterweight 200 to rise to achieve the lifting door 12 to close the passage opening 11, and the amplitude of the lifting door 12 driven by the door panel adjustment device 300 is increased to meet the height requirements of the lifting door 12. This structural setting scheme provides flexibility and adaptability for applications that require a larger 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, and can achieve customized control of the movement of the lifting door 12 to meet the requirements of different needs and application scenarios, and more easily adapt to passage openings 11 of different sizes and heights.

[0104] Specifically, Figure 2 and Fig. 9As shown, the passage opening and closing device 100 also includes a support frame 17 disposed inside the battery swap station 500, and the interior of the support frame 17 forms a charging area 16. In this embodiment, the counterweight 200 and the displacement amplification mechanism 400 are both disposed on the support frame 17 and are both located on the side of the support frame 17, and preferably, the counterweight 200 and the displacement amplification mechanism 400 are both located on the same side of the support frame 17.

[0105] In this embodiment, the counterweight mechanism and the displacement amplification mechanism 400 are arranged on the support frame 17, so as 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 prevents the counterweight mechanism and the displacement amplification mechanism 400 from interfering with the movement of the battery swapping device 600 and the battery pack to be carried within the charging area 16 of the battery swapping station 500, and avoids interfering with the normal transportation process of the battery pack.

[0106] Among them, the displacement amplification mechanism 400 and the counterweight 200 are arranged on the support frame 17 on the same side and connected by the second pulley set 15 to form a synergistic system, which helps to achieve more precise and smooth movement of the counterweight 200 through mutual coordination, thereby making the movement of the lifting door 12 more stable and vertical.

[0107] Specifically, the door panel adjustment device 300 is arranged on the ground near the charging area 16 between the support frames 17 on both sides, and is preferably arranged in the middle position of the travel path of the battery exchange equipment 600. Several pulleys of the first pulley group 14 are provided at the bottom end of the support frame 17 to realize the transmission connection between the door panel adjustment device 300 and the displacement amplification mechanism 400, and several pulleys of the first pulley group 14 and several pulleys of the second pulley group 15 are also provided at one end of the support frame 17 close to the counterweight 200 and away 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 may also be arranged on the support frame 17 on both sides of the moving direction X of the battery exchange device 600, that is, the counterweight 200 and the displacement amplification mechanism 400 are arranged on the support frame 17 on each side, so as to change the lifting and lowering of the lifting door 12 through dual effects, and also balance the force of the counterweight 200 to drive the lifting door 12 to move.

[0109] Preferably, if Figure 5 and Fig.12As shown, in the present embodiment, the displacement amplification mechanism 400 amplifies the first displacement into the second displacement by adopting a movable pulley group. The fixed pulley group, that is, a plurality of movable pulleys, is adopted. Compared with other schemes for amplifying the stroke by a lever structure, the movement path of the counterweight 200 is affected by changing the direction of force transmission, thereby changing the moving distance of the counterweight 200. Therefore, this method can most directly and efficiently change the movement amplitude 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 support platform 41 and a plurality of pulleys.

[0111] Specifically, the supporting platform 41 is connected to the door panel adjustment device 300 through the chain of the second pulley group 15, and a part of the pulleys are arranged on the supporting platform 41 in sequence and at intervals, and this part of the pulleys are movable pulleys, and the other part of the pulleys are arranged on the support frame 17 in sequence and at intervals corresponding to the pulleys on the supporting platform 41, and this part of the pulleys are fixed pulleys, and one end of the chain of the second pulley group 15 is fixedly connected to the support frame 17, and the other end is connected to the counterweight 200 after passing through several pulleys in sequence. In this way, the first displacement of the door panel adjustment device 300 can be amplified to the second displacement of the counterweight 200 by connecting the movable pulley and the fixed pulley in series and by utilizing the movable pulley to increase the moving displacement.

[0112] In this embodiment, this structural form is adopted to fully realize the amplification effect of the chain transmission, so that when the second pulley group 15 is transmitting, the counterweight 200 can amplify the lifting range of the lifting door 12 through the action of several pulleys, thereby realizing the movement of the lifting door 12 in a larger range. At the same time, the several pulleys in the displacement amplification mechanism 400 are designed in a graded structure, with one part arranged on the bearing platform 41 and the other part 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 movement, 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 cross-arranged. By cross-arranging the pulleys, the chain of the second pulley group 15 can be evenly stressed during movement, which helps to reduce the lateral swing of the chain during movement, making the movement of the displacement amplification mechanism 400 more stable, and ensuring the verticality and stability of the lifting door 12 during movement.

[0114] In addition, if Figure 3 , Fig.10 and Fig.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 of the lifting door 12.

[0115] In this embodiment, the height of the counterweight 200 is set to be the same as the maximum height of the lifting door 12, which helps to achieve vertical balance. Such a design can ensure that the lifting door 12 can maintain balance throughout the movement of the lifting door 12 and prevent instability 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 lifting door 12 to move, thereby reducing the energy consumption of the entire door panel adjustment device 300.

[0116] like Fig.13 and Fig.14 As shown, fixing members 121 fixedly connected to the first pulley block 14 are provided on both sides of the lifting door 12 along the moving direction X of the battery exchange device 600, and the lifting door 12 is connected to the first pulley block 14 through the fixing members 121. Preferably, the number of fixing members 121 is multiple, and they are arranged in pairs on both sides of the lifting door 12 to be transmission-connected to the first pulley block 14.

[0117] In addition, a slide rail 131 matched with the fixing member 121 is provided at a position of the door frame 13 corresponding to the fixing member 121 , so as to allow the lifting door 12 to move and provide guidance for the movement of the lifting door 12 .

[0118] In the present technical solution, the setting of the fixing member 121 helps to enhance the stability of the movement of the lifting door 12. By being fixed on both sides of the lifting door 12, it can effectively prevent the lifting door 12 from swaying or deviating from the track during movement, thereby improving the balance of the movement of the lifting door 12.

[0119] like Figure 1 and Figure 8 As shown, a battery swap station 500 is also disclosed. The battery swap 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 swap station 500 to realize the opening and closing of the channel opening 11 in the battery swap station 500.

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

[0121] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
