Description

Technical Field

[0001] The present invention relates to the field of battery swapping, and particularly to a channel opening and closing device and a battery swapping station including the same. Background Art

[0002] In the prior art, most battery swapping stations use lifting doors to open and close the channels, and usually use a driving mechanism to drive the movement of the lifting door. However, there are some problems in the prior art, mainly involving the design and operation of the driving mechanism being restricted by the internal space of the battery swapping station.

[0003] For example, due to the limited internal space of the battery swapping station, the design of traditional driving mechanisms may be difficult to adapt to this limitation. The volume and shape of the driving mechanism may be restricted by the space, resulting in difficulty in normal driving operation or being restricted in the operation of driving the lifting door to open and close, thus affecting the smoothness of the battery swapping equipment entering and exiting the channel. Secondly, if only a driving mechanism is used to drive the movement of the lifting door, it may cause an excessive load on the driving mechanism, thereby reducing its service life. Since the lifting door needs to overcome gravity during movement, if the design of the driving mechanism is not reasonable, it may cause an excessive load, accelerating the wear of the driving mechanism and reducing its reliability and service life.

[0004] Generally speaking, there are some deficiencies in the battery swapping stations in the prior art, mainly manifested in that the driving mechanism for driving the movement of the lifting door cannot work properly in a limited space and the problem of excessive load that may be faced during the movement of the lifting door. Therefore, a solution is urgently needed to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects that the driving mechanism cannot work properly in a limited space and the excessive load that may be faced during the movement of the lifting door in the prior art, and to provide a channel opening and closing device and a battery swapping station including the same.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A channel opening and closing device, the channel opening and closing device includes a channel for the battery swapping equipment to enter and exit the charging area and a lifting door capable of opening and closing the channel, and the channel opening and closing device further includes a mounting door frame, a linear driving mechanism, a first stroke amplification mechanism, and a commutation mechanism.

[0008] In which, the mounting door frame is enclosed to define the passage opening, the linear drive mechanism, the first stroke amplification mechanism and the reversing mechanism are all arranged in the mounting door frame and are all located above the lifting door, the lifting door is also arranged in the mounting door frame, and the lifting door is sequentially connected to the linear drive mechanism through the reversing mechanism and the first stroke amplification mechanism, the first stroke amplification mechanism is used to amplify the first stroke of horizontal movement output by the linear drive mechanism into a second stroke of horizontal movement, and the reversing mechanism is used to convert the second stroke of horizontal movement into a third stroke that drives the lifting door to move up and down.

[0009] In the present technical solution, a lifting door is provided to open and close the passageway, thereby ensuring the safety and isolation of the charging area. Furthermore, a linear drive mechanism is provided and the lifting door is driven to lift and lower via a first stroke amplification mechanism and a reversing mechanism. First, the characteristic of the first stroke amplification mechanism to amplify the moving stroke enables the smaller moving stroke of the linear drive mechanism to meet the displacement requirements for opening and closing the lifting door. Secondly, the characteristic of the reversing mechanism to change the transmission direction is utilized so that the horizontally arranged linear drive mechanism can drive the lifting door to move up and down. Finally, through the combination of the first stroke amplification mechanism and the reversing mechanism, the linear drive mechanism can be used to drive the lifting door to lift and lower, and a horizontal arrangement scheme is adopted to reasonably utilize the limited space in the installation door frame, so that the setting of the linear drive mechanism will not cause the overall height dimension of the passageway opening and closing device to be too high.

[0010] Preferably, the passage opening and closing device further comprises a counterweight member which is transmission-connected to the lifting door in the vertical direction, and the force exerted by the gravity of the counterweight member on the lifting door is opposite to the gravity direction of the lifting door;

[0011] The linear drive mechanism is an electric push rod.

[0012] In the present technical solution, a counterweight is arranged to be transmission-connected with the lifting door in the vertical direction, and the gravity of the counterweight acts on the lifting door in the vertical upward direction to reduce or even balance the gravity of the lifting door, so that the load required for the linear drive mechanism for driving the lifting door to open and close can be reduced.

[0013] Furthermore, by using an electric push rod as a linear drive mechanism to drive the opening and closing of the lifting door, the control accuracy of the passage opening and closing device is improved by utilizing the characteristics of the electric push rod such as high control accuracy and the ability to stop midway. In addition, the problem of the small output torque of the electric push rod is solved by providing a counterweight to reduce or balance the gravity of the lifting door, and the problem of the short telescopic length of the electric push rod is also solved by providing a first stroke amplification mechanism to amplify the stroke.

[0014] Preferably, the channel opening and closing device further includes a second stroke amplification mechanism. Both the second stroke amplification mechanism and the counterweight are disposed within the installation doorframe. The counterweight is in driving connection with the lifting door in the vertical direction through the second stroke amplification mechanism. The second stroke amplification mechanism is configured to amplify a fourth stroke of the lifting and lowering movement of the counterweight into a fifth stroke of the lifting and lowering movement of the lifting door.

[0015] When the lifting door rises to open the channel opening, the counterweight is located above the channel opening. Along the thickness direction of the installation doorframe, the lifting door and the counterweight are arranged in a staggered manner.

[0016] In this technical solution, by providing a second stroke amplification mechanism to establish a driving connection between the counterweight and the lifting door, the characteristic of the second stroke amplification mechanism to amplify the stroke is utilized, so that the magnitude of the lifting and lowering displacement of the counterweight can be smaller than the displacement required for the opening and closing of the lifting door. By reducing the magnitude of the lifting and lowering displacement of the counterweight, the counterweight can be installed within the installation doorframe, and the downward movement of the counterweight caused by the rising of the lifting door will not affect the normal passage of the channel opening. In addition, by arranging the lifting door and the counterweight in a staggered manner along the thickness direction of the installation doorframe, a compact layout of the structure is achieved, so that the space occupied by the entire channel opening and closing device can be further reduced.

[0017] Preferably, the second stroke amplification mechanism includes a second movable pulley provided on the counterweight and at least one fixed pulley provided on the installation doorframe. One end of a transmission chain led out from the second movable pulley of the second stroke amplification mechanism is provided on the installation doorframe, and the other end passes through at least one of the fixed pulleys and is connected to the lifting door.

[0018] In this technical solution, the method of providing a second movable pulley on the counterweight helps the amplitude of the movement of the counterweight, avoids the range of its movement being too large to interfere with the normal operation of the battery swapping device, makes the movement of the counterweight more flexible within a limited space, and is suitable for occasions where the movement area is restricted.

[0019] Preferably, the connection end of the second stroke amplification mechanism and the lifting door is provided at the central axis of the lifting door.

[0020] In this technical solution, placing the connection end of the second stroke amplification mechanism on the central axis of the lifting door can achieve balanced force transmission, helps to ensure the stable movement of the lifting door during the opening and closing processes, reduces the uneven force and torque it receives. And it also helps to prevent the lifting door from being skewed or swinging during the movement process, improving the reliability of the movement.

[0021] Preferably, the counterweight and / or the linear driving mechanism is disposed on one side of the installation doorframe facing the charging area.

[0022] In this technical solution, placing the linear drive mechanism and the counterweight on one side of the charging area, that is, inside the battery swapping station, can effectively protect these key components from the influence of the external environment or other potential damage factors, help improve their stability and reliability, reduce maintenance requirements, and also improve the aesthetics of the battery swapping station to a certain extent.

[0023] Preferably, the first stroke amplification mechanism includes a first movable pulley, the reversing mechanism includes a first steering wheel, the linear mobile end of the linear drive mechanism is connected to the first movable pulley, and the transmission chain led out by the first movable pulley passes through the first steering wheel and then is connected to the top of the lifting door.

[0024] In this technical solution, by arranging the first movable pulley on the linear mobile end of the linear drive mechanism in the first stroke amplification mechanism, the transmission chain can be driven along the moving direction of the linear mobile end of the linear drive mechanism, enabling the drive mechanism to operate in a limited space to ensure the normal movement of the lifting door.

[0025] Preferably, there are two transmission chains led out from the first movable pulley, and the steering wheel further includes a second steering wheel. The first steering wheel and the second steering wheel are respectively arranged on both sides of the installation door frame;

[0026] One of the transmission chains passes through the first steering wheel and then is connected to the top of the lifting door on the side where the first steering wheel is located;

[0027] The other transmission chain passes through the first steering wheel and the second steering wheel on the other side in sequence and then is connected to the top of the lifting door on the side where the second steering wheel is located.

[0028] In this technical solution, by adopting the first stroke amplification mechanism with this structural form, it helps to balance the movement of the lifting door, ensure that the lifting door remains stable during the lifting process, and reduce vibrations and swings caused by imbalance. Moreover, the reasonable setting of the first steering wheel and the second steering wheel helps to guide the transmission chain to be driven along the required direction, ensuring that the transmission chain does not deviate from the direction during the power transmission process.

[0029] Preferably, a buffer structure is provided at the bottom end of the lifting door along its moving direction and facing the channel opening. The buffer structure extends along the moving direction of the battery swapping device, and a receiving groove for accommodating the buffer structure is provided on the ground.

[0030] In the present technical solution, the main purpose of setting up the buffer structure is to prevent the driver from opening the door and getting off the vehicle during the battery swapping process, because during the battery swapping process, the lift door is in a state of opening the passage, and the buffer structure is just opposite to the door of the battery swapping vehicle, so that the door cannot be opened, which can avoid personal injury. Secondly, it also helps to reduce the collision with the ground or other structures when the lift door closes the passage, thereby reducing the impact force, helping to protect the lift door and related mechanical parts from excessive impact, reducing damage and extending the service life. In addition, by extending the buffer structure along the moving direction of the battery swapping equipment, the lift door can be in contact with the ground more smoothly when closing the passage by increasing the contact surface. At the same time, a receiving groove for accommodating the buffer structure is provided on the ground, which helps to provide a stable support for the buffer structure, and helps to ensure that the buffer structure can effectively play its role and remain in the proper position.

[0031] Preferably, there are a plurality of buffer structures, and the plurality of buffer structures are arranged in sequence and spaced apart along the width direction of the lifting door.

[0032] In this technical solution, multiple buffer structures are arranged at intervals along the width direction of the lifting door, which can not only further protect the driver during the battery replacement process, but also help to evenly distribute the impact force. Such a design can effectively disperse the impact force generated when the lifting door closes the channel opening, reduce the force borne by each buffer structure, reduce local pressure, and help to increase the service life of each buffer structure. Moreover, the interval arrangement of multiple buffer structures also helps to improve the stability of the lifting door when closing the channel opening. This evenly distributed buffer structure can prevent the lifting door from swinging or shaking unevenly when closing the channel opening, ensuring that its movement is more stable and controllable.

[0033] Preferably, a position detection component is provided at a position of the installation door frame close to the passage opening, and the position detection component is electrically connected to the linear drive mechanism;

[0034] The position of the in-place detection component on the mounting door frame is set to: when the lifting door moves to a preset position, it can contact the detection end of the in-place detection component to stop the linear drive mechanism from continuing to drive the first stroke amplification mechanism to drive the lifting door to move.

[0035] In this technical solution, by using the in-place detection component, it is possible to accurately detect whether the lifting door has moved to the preset position, and transmit the position of the lifting door to the linear drive mechanism in a timely manner by signal transmission, so that the linear drive mechanism can perform the next step of work according to the received signal. This design helps to ensure that the lifting door can accurately stop at the required position, improve the opening and closing accuracy of the passage opening, thereby preventing the lifting door from moving excessively or inaccurately, ensuring the safety performance of the passage opening and closing device, and avoiding potential safety hazards caused by the lifting door staying in the incorrect position.

[0036] Preferably, slide rails extending along the moving direction of the lifting door are provided on both sides of the installation door frame for the lifting door to move, and sliders adapted to the slide rails are provided on both sides of the lifting door. The lifting door moves along the extension direction of the slide rails through the sliders.

[0037] In this technical solution, the design of the slide rails and sliders helps to ensure that the lifting door moves smoothly during the movement process, improves the stability of the operation of the passage opening and closing device, and prevents the lifting door from deviating or disengaging from the installation door frame when moving.

[0038] A battery swapping station includes the passage opening and closing device as described in any one of the above.

[0039] In this technical solution, the passage opening and closing device adopting the above structural form can effectively control the opening and closing of the passage opening in the battery swapping station, provide a flexible operation passage for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0040] The positive and progressive effects of the present invention are as follows:

[0041] 1. For the said passage opening and closing device, by setting a lifting door to open and close the passage opening, the safety and isolation of the charging area are ensured. Further, by setting a linear drive mechanism and driving the lifting door to move up and down through a first stroke amplification mechanism and a reversing mechanism. First, by utilizing the characteristic of the first stroke amplification mechanism to amplify the moving stroke, the smaller moving stroke of the linear drive mechanism can meet the displacement requirements for opening and closing the lifting door. Secondly, by utilizing the characteristic of the reversing mechanism to change the transmission direction, the horizontally arranged linear drive mechanism can drive the lifting door to move up and down. Finally, through the combination of the first stroke amplification mechanism and the reversing mechanism, the linear drive mechanism can be used to drive the lifting door to move up and down, and a horizontal layout scheme is adopted to reasonably utilize the limited space within the installation door frame, so that the setting of the linear drive mechanism will not cause the overall height dimension of the passage opening and closing device to be too high.

[0042] 2. For the battery swapping station adopting the said passage opening and closing device, it can effectively control the opening and closing of the passage opening in the battery swapping station, provide a flexible operation passage for the battery swapping equipment, and realize safe and orderly battery replacement services.

[0071] 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 hereby.

[0072] The present invention provides a battery swapping station for providing battery swapping services to vehicles driving into the battery swapping station. Among them, the battery swapping station includes a battery swapping area and a charging area. The area for vehicles to drive into is the battery swapping area. In the battery swapping area, there is battery swapping equipment for disassembling and assembling the battery loaded on the vehicle. After the disassembly and assembly are completed, the battery swapping equipment will drive into the charging area through the passage opening to perform a charging operation on the battery removed from the vehicle. In order to separate the charging area and the battery swapping area while not affecting the normal driving of the battery swapping equipment, a passage opening opening and closing device is also provided at the position of the passage opening of the battery swapping station.

[0073] As Figures 1-7 shown, this embodiment provides a preferred structural setting scheme for the passage opening opening and closing device 100. Among them, the function of the passage opening opening and closing device 100 is to close and open the passage opening 11 of the battery swapping station. The switching between its open state and closed state is respectively as Figure 1 and Figure 4 shown, where Figure 1 is the open state, and Figure 4 is the closed state. Among them, the passage opening opening and closing device 100 specifically includes a lifting door 12, a mounting door frame 13, a linear driving mechanism 14, a first stroke amplification mechanism 15 and a reversing mechanism 17. The mounting door frame 13 encloses the area where the passage opening 11 is located. The linear driving mechanism 14, the first stroke amplification mechanism 15 and the reversing mechanism 17 are all arranged inside the mounting door frame 13 and are all located above the lifting door 12. The lifting door 12 is also arranged on the mounting door frame 13 and completely covers the passage opening 11. By driving the lifting door 12 to move upward, the purpose of opening the passage opening 11 is achieved. By setting the lifting door 12 to open and close the passage opening 11, the safety and isolation of the charging area are ensured.

[0074] Specifically, as Figure 1As shown, in this embodiment, the lifting door 12 is driven to rise by the linear drive mechanism 14, but the lifting door 12 is not directly connected to the linear drive mechanism 14, but is sequentially connected to the linear drive mechanism 14 through the reversing mechanism 17 and the first stroke amplification mechanism 15. The specific structure is as follows Figure 5 As shown, the first stroke amplification mechanism 15 is used to amplify the first horizontal stroke output by the linear drive mechanism 14 into a second horizontal stroke. At the same time, the reversing mechanism 17 is further used to convert the second horizontal stroke into a third stroke that drives the lifting door 12 to move up and down.

[0075] For this structural setting scheme, firstly, the first stroke amplification mechanism 15 is used to amplify the moving stroke so that the smaller moving stroke of the linear drive mechanism 14 can meet the displacement requirements of the opening and closing of the lifting door 12. Secondly, the reversing mechanism 17 is used to change the transmission direction so that the horizontally arranged linear drive mechanism 14 can drive the lifting door 12 to move up and down.

[0076] Finally, through the combination of the first stroke amplification mechanism 15 and the reversing mechanism 17, the linear drive mechanism 14 can be used to drive the lifting door 12 to rise and fall, and a horizontal arrangement is adopted to rationally utilize the limited space within the installation door frame 13, so that the setting of the linear drive mechanism 14 will not cause the overall height dimension of the passage opening and closing device 100 to be too high.

[0077] Specifically, the first stroke amplification mechanism 15 in this embodiment is implemented by means of a movable pulley, so the ratio of the first stroke of horizontal movement output by the linear drive mechanism 14 to the amplified second stroke of horizontal movement is 1:2, so that the stroke output by the linear drive mechanism 14 is amplified twice to drive the lifting door 12 to lift and lower.

[0078] Of course, in other embodiments, other mechanisms with stroke amplification capability may be used to achieve the purpose of stroke amplification, such as a lever mechanism, etc. By adjusting the fulcrum of the lever mechanism, the stroke amplification ratio is not necessarily limited to 2 times, but can be set as needed. In this embodiment, a movable pulley is used as a specific implementation scheme of the first stroke amplification mechanism 15, mainly considering the relatively simple structure and high reliability of the movable pulley mechanism.

[0079] In addition, the reversing mechanism 17 in this embodiment is specifically implemented in the form of a reversing wheel. Compared with other optional reversing schemes, the structure using a reversing wheel to change the transmission direction is simpler and more reliable, so as to adapt to the high-frequency opening and closing working scenario of the channel opening and closing device.

[0080] It should be clearly stated that, in this embodiment, Figure 1As shown, when the lifting door 12 is in the closed state, it completely covers the passage opening 11, so as to effectively prevent personnel and foreign objects from invading the charging area of the battery swapping station, while improving the isolation effect between the charging area and the outside world and meeting the requirements of dust prevention, heat preservation, etc. Of course, in other embodiments, the lifting door 12 can also cover the passage opening 11 partially or semi - covered as needed, and the specific covering degree can be set according to actual needs.

[0081] As Figures 1-6 shown, further, the passage opening opening and closing device 100 further includes a counterweight 18 that is vertically drivably connected to the lifting door 12. The force exerted on the lifting door 12 by the gravity of the counterweight 18 is opposite to the direction of the gravity of the lifting door 12. By setting the counterweight 18 to be vertically drivably connected to the lifting door 12 and making the gravity of the counterweight 18 act on the lifting door 12 in the vertically upward direction, the gravity of the lifting door 12 can be reduced or even balanced, so that the load required to drive the lifting door 12 to open and close can be reduced. Therefore, in this embodiment, a push - rod motor is specifically used as the linear drive mechanism 14 for driving the lifting door 12 to open and close. By utilizing the characteristics of high control precision and the ability to stop midway of the push - rod motor, the control precision of the passage opening opening and closing device 100 is improved. In addition, the problem of the small output torque of the push - rod motor is solved by setting the counterweight 18 to reduce or balance the gravity of the lifting door 12, and the problem of the short telescopic length of the push - rod motor is also solved by setting the first stroke amplification mechanism 15 to amplify the stroke.

[0082] In this embodiment, the linear drive mechanism 14 extends along the width direction of the installation door frame 13, and the output end of the linear drive mechanism 14 also moves along the width direction of the installation door frame 13 to drive the first stroke amplification mechanism 15 to output an amplified driving stroke through the amplification principle of the movable pulley.

[0083] At the same time, the passage opening opening and closing device 100 further includes a second stroke amplification mechanism 16. Both the second stroke amplification mechanism 16 and the counterweight 18 are arranged inside the installation door frame 13, and the counterweight 18 is vertically drivably connected to the lifting door 12 through the second stroke amplification mechanism 16. The second stroke amplification mechanism 16 is used to amplify the fourth stroke of the lifting and lowering movement of the counterweight 18 into the fifth stroke of the lifting and lowering movement of the lifting door 12. By utilizing the characteristic of the second stroke amplification mechanism 16 to amplify the stroke, a smaller displacement stroke of the counterweight 18 can drive the lifting door 12 to generate a larger displacement stroke, so that the magnitude of the lifting and lowering displacement of the counterweight 18 can be smaller than the displacement required for the opening and closing of the lifting door 12.

[0084] Moreover, when the lifting door 12 rises to open the passage opening 11, the counterweight 18 is located above the passage opening 11. By reducing the magnitude of the lifting displacement of the counterweight 18, the counterweight 18 can be installed within the installation doorframe 13, and the descent of the counterweight 18 caused by the rise of the lifting door 12 will not affect the normal passage of the passage opening 11.

[0085] On this basis, this embodiment further provides a preferred layout scheme of the counterweight at the passage opening: As Figure 7 shown, along the thickness direction of the installation doorframe 13, the lifting door 12 and the counterweight 18 are arranged with a left-right offset. Specifically, as Figure 7 shown, the counterweight 18 is located on the left side in the figure, while the lifting door 12 is located on the right side in the figure. Therefore, when the counterweight 18 drives the lifting door 12 to move to the required position, that is, when both move up and down along the height direction of the passage opening 11, the lifting door 12 and the counterweight 18 do not interfere with each other and will not affect the function of the lifting door 12 to normally open and close the passage opening 11. Moreover, by arranging the lifting door 12 and the counterweight 18 with an offset along the thickness direction of the installation doorframe 13, the space within the installation doorframe 13 can be fully utilized to achieve a compact layout of the structure, so that the height space occupied by the entire passage opening opening and closing device 100 can be further reduced.

[0086] As Figures 1-6 shown, the connection end of the second stroke amplification mechanism 16 and the lifting door 12 is set at the central axis of the lifting door 12, which can achieve balanced force transmission, contribute to ensuring the stable movement of the lifting door 12 during the opening and closing processes, and reduce the uneven forces and torques it receives. Moreover, it also helps to prevent the lifting door 12 from tilting or swinging during the movement process, improving the reliability of the movement.

[0087] In this embodiment, the second stroke amplification mechanism 16 also realizes the stroke amplification function by relying on the way of a movable pulley. Therefore, the stroke amplification ratio is 1:2. The second stroke amplification mechanism 16 specifically includes a second movable pulley 161 provided on the counterweight 18 and two parallel fixed pulleys 162 provided on the installation doorframe 13. The installation positions of the two fixed pulleys 162 are as Figure 1 shown. One of the fixed pulleys 162 is provided on the installation doorframe 13 and is located at the central axis of the lifting door 12, and the other fixed pulley 162 is arranged along the width direction of the installation doorframe 13 between the counterweight 18 and the connection end of the second stroke amplification mechanism 16 and the lifting door 12.

[0088] Then one end of the transmission chain led out from the second movable pulley 161 of the second stroke amplification mechanism 16 is provided on the installation doorframe 13, and the other end passes through the two fixed pulleys 162 and is connected to the lifting door 12.

[0089] In this embodiment, the second movable pulley 161 is arranged on the counterweight 18. By utilizing the principle of a movable pulley to amplify the stroke, the large-scale movement of the counterweight 18 is avoided, thereby preventing its movement range from being too large to interfere with the normal operation of the battery swapping device. This makes the movement of the counterweight 18 more flexible within a limited space and is suitable for occasions where the movement area is restricted.

[0090] Preferably, both the counterweight 18 and the linear drive mechanism 14 are arranged on the side of the installation doorframe 13 facing the charging area, that is, inside the battery swapping station. This can effectively protect these key components from the influence of the external environment or other potential damage factors, contribute to improving their stability and reliability, reduce maintenance requirements, and also improve the aesthetics of the battery swapping station to a certain extent. Of course, in other embodiments, the counterweight 18 can also be arranged on the side facing the battery swapping area, and the specific layout position can be adjusted as needed.

[0091] As Figure 1 shown, the first stroke amplification mechanism 15 in this embodiment uses the principle of a movable pulley to achieve the purpose of amplifying the stroke. It includes a first movable pulley 151. The reversing mechanism 17 includes a first steering wheel 171. The linear moving end of the linear drive mechanism 14, that is, the output end of the linear drive mechanism 14, is connected to the first movable pulley 151. The transmission chain led out from the first movable pulley 151 passes through the first steering wheel 171 and then is connected to the top of the lifting door 12.

[0092] In this embodiment, by arranging the first movable pulley 151 on the linear moving end of the linear drive mechanism 14 in the first stroke amplification mechanism 15, the transmission chain can be driven along the moving direction of the linear moving end of the linear drive mechanism 14, enabling the drive mechanism to operate in a limited space to ensure the normal movement of the lifting door 12.

[0093] Furthermore, there are two transmission chains led out from the first movable pulley 151, and the reversing mechanism 17 further includes a second steering wheel 172. The first steering wheel 171 and the second steering wheel 172 are respectively arranged on both sides of the installation doorframe 13, that is, the first steering wheel 171 and the second steering wheel 172 are respectively located above the lifting door 12 and on both sides of the lifting door 12.

[0094] Specifically, among the two transmission chains led out from the first movable pulley 151, one transmission chain passes through the first steering wheel 171 and then is connected to the top of the lifting door 12 on the side where the first steering wheel 171 is located, and the other transmission chain passes through the first steering wheel 171 and the second steering wheel 172 on the other side in sequence and then is connected to the top of the lifting door 12 on the side where the second steering wheel 172 is located.

[0095] In this embodiment, by adopting the first stroke amplification mechanism 15 with such a structural form, it helps to balance the movement of the lifting door 12, ensures that the lifting door 12 remains stable during the lifting process, and reduces vibrations and swings caused by imbalance. Moreover, the reasonable setting of the first steering wheel 171 and the second steering wheel 172 helps to guide the transmission chain to drive along the required direction, ensuring that the transmission chain does not deviate from the direction during the power transmission process.

[0096] As Figure 3 and Figure 6 shown, a buffer structure 19 is provided at the bottom end of the lifting door 12 along its moving direction and facing the channel opening 11. The buffer structure 19 extends along the moving direction of the battery swapping device, and a receiving groove for accommodating the buffer structure 19 (not shown in the figure) is provided on the ground. In this embodiment, the buffer structure 19 is a plate-like structure and extends from the bottom of the lifting door 12 towards the inside of the battery swapping station.

[0097] In this embodiment, the main purpose of setting the buffer structure 19 is to prevent the driver from opening the car door and getting out during the battery swapping process. Because during the battery swapping process, the lifting door 12 is in the state of opening the channel opening 11, and the buffer structure 19 is exactly opposite the car door of the battery swapping vehicle, making the car door unable to be opened, which can avoid causing personal injuries. Secondly, it also helps to slow down the collision with the ground or other structures when the lifting door 12 closes the channel opening 11, thereby reducing the impact force, helping to protect the lifting door 12 and related mechanical components from excessive impact, reducing damage and extending the service life. And by extending the buffer structure 19 along the moving direction of the battery swapping device, the way of increasing the contact surface makes the lifting door 12 contact the ground more smoothly when closing the channel opening 11. At the same time, a receiving groove for accommodating the buffer structure 19 is provided on the ground, which helps to provide a stable support for the buffer structure 19, helps to ensure that the buffer structure 19 can effectively play its role and remain in the appropriate position.

[0098] Preferably, the number of the buffer structures 19 is multiple, and the multiple buffer structures 19 are arranged at intervals in sequence along the width direction of the lifting door 12.

[0099] In this embodiment, multiple buffer structures 19 are arranged at intervals along the width direction of the lifting door 12, which can not only further protect the driver during the battery replacement process, but also help to evenly distribute the impact force. Such a design can effectively disperse the impact force generated when the lifting door 12 closes the passage opening 11, reduce the force borne by each buffer structure 19, reduce local pressure, and help to increase the service life of each buffer structure 19. Moreover, the interval arrangement of multiple buffer structures 19 also helps to improve the stability of the lifting door 12 when closing the passage opening 11. Such evenly distributed buffer structures 19 can prevent the lifting door 12 from swinging or shaking unevenly when closing the passage opening 11, ensuring that its movement is more stable and controllable.

[0100] like Figures 1-2 As shown, an in-place detection component 200 is provided at a position of the installation door frame 13 near the passage opening 11. The in-place detection component 200 is preferably arranged above the installation door frame 13 to detect whether the lifting door 12 rises to a preset position, and the in-place detection component 200 is electrically connected to the linear drive mechanism 14.

[0101] Among them, the position of the in-place detection component 200 on the door frame 13 is set to: when the lifting door 12 moves to a preset position, it can contact the detection end of the in-place detection component 200. After the in-place detection component 200 and the lifting door 12 contact, a stop driving signal is sent to the linear drive mechanism 14 through signal transmission to stop the linear drive mechanism 14 from continuing to drive the first stroke amplification mechanism 15 to drive the lifting door 12 to move.

[0102] In this embodiment, the in-position detection component 200 can be used to accurately detect whether the lifting door 12 has moved to the preset position, and the position of the lifting door 12 can be timely sent to the linear drive mechanism 14 in the form of a signal, so that the linear drive mechanism 14 can perform the next step according to the received signal. This design helps to ensure that the lifting door 12 can accurately stop at the required position, improve the opening and closing accuracy of the passage opening 11, thereby preventing the lifting door 2 from moving excessively, ensuring the safety performance of the passage opening and closing device 100, and avoiding the safety hazards caused by the lifting door 12 staying in an incorrect position.

[0103] Preferably, there are two in-place detection components 200, both of which are arranged on the door frame 13 and located above the lifting door 12, so as to perform double detection on the movement of the lifting door 12. When the in-place detection component 200 on one side fails, the position can also be detected by the in-place detection component 200 on the other side. The advantage of setting two is that the accuracy of the position detection of the lifting door 12 can be further improved.

[0104] Specifically, Figure 2As shown, the in-place detection component 200 in this embodiment includes a touch arm 21 and a sensor 22. Among them, the touch arm 21 is used to contact the lifting door 12, and the sensor 22 is connected to the touch arm 21 and electrically connected to the linear drive mechanism 14. After the lifting door 12 is to open the passage opening 11 and rise to a preset position, the lifting door 12 will push the touch arm 21 to move. When the lifting door 12 opens the passage opening 11, the touch arm 21 reaches its limit position and sends a signal to stop the operation to the linear drive mechanism 14 through the sensor 22.

[0105] In this embodiment, by monitoring the position of the touch arm 21 through the sensor 22, the position of the lifting door 12 can be accurately detected. And through the mechanical way that the lifting door 12 contacts the touch arm 21, the detection of the in-place detection component 200 is more reliable, and it can send a signal to the linear drive mechanism 14 in time. This real-time feedback ensures that the in-place detection component 200 monitors the position of the lifting door 12 in a timely and accurate manner.

[0106] As Figures 1-6 shown, on both sides of the installation door frame 13, there are slide rails 131 extending along the moving direction of the lifting door 12 for the lifting door 12 to move, and on both sides of the lifting door 12, there are sliding blocks 121 adapted to the slide rails 131. The sliding blocks 121 are adapted to the slide rails 131. Preferably, the sliding blocks 121 are embedded in the slide rails 131. The lifting door 12 moves along the extension direction of the slide rails 131 through the sliding blocks 121 to realize the movement of the lifting door 12 on the installation door frame 13.

[0107] In this embodiment, the design of the slide rails 131 and the sliding blocks 121 helps to ensure that the lifting door 12 maintains a stable movement during the movement process, improves the stability of the operation of the passage opening opening and closing device 100, and prevents the lifting door 12 from deviating or disengaging from the installation door frame 13 when moving.

[0108] More preferably, the number of the sliding blocks 121 on each side can be two, and they are arranged in pairs on both sides of the lifting door 12 to realize multi-point connection with the lifting door 12 and effectively balance the acting force generated during the movement of the lifting door 12.

[0109] It should be clearly stated that the passage opening opening and closing device 100 in this embodiment is applied in the battery swapping station to realize the opening and closing of the passage opening of the battery swapping station. However, in other embodiments, the passage opening opening and closing device 100 can also be applied to other devices in the battery swapping field to achieve the purpose of reliably opening and closing the passage opening.
