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, battery swap stations often use lift doors to open and close the passageway, and usually use a drive mechanism to drive the lift door to move. However, there are some problems in the prior art, mainly related to the fact that the design and operation of the drive mechanism are limited by the internal space of the battery swap station.

[0003] For example, due to the limited internal space of the battery swap station, the traditional drive mechanism design may be difficult to adapt to this limitation. The size and shape of the drive mechanism may be constrained by space, making it difficult to drive normally or being restricted in the operation of driving the lifting door to open and close, thereby affecting the smoothness of the entrance and exit of the battery swap equipment. Secondly, if the drive mechanism is used alone to drive the movement of the lifting door, it may cause the load of the drive mechanism to be too large, thereby reducing its service life. Since the lifting door needs to overcome gravity during movement, if the design of the drive mechanism is not reasonable, it may cause excessive load, accelerate the wear of the drive mechanism, and reduce its reliability and service life.

[0004] In summary, there are some deficiencies in the existing battery swap stations, mainly manifested in the fact that the driving mechanism for driving the lifting door to move cannot work normally in a limited space and the lifting door may face excessive load during movement. Therefore, a solution is urgently needed to solve the above problems. Utility Model Content

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

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] A channel opening and closing device, the channel opening and closing device comprising a channel opening for a battery exchange device to enter and exit a charging area and a lifting door capable of opening and closing the channel opening, the channel opening and closing device also comprising a mounting door frame, a linear drive mechanism, a first stroke amplification mechanism and a reversing 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 passage opening and closing device further comprises a second stroke amplification mechanism, the second stroke amplification mechanism and the counterweight are both arranged in the installation door frame, the counterweight is connected to the lifting door in a vertical direction through the second stroke amplification mechanism, and the second stroke amplification mechanism is used to amplify the fourth stroke of the lifting movement of the counterweight into the fifth stroke of the lifting movement of the lifting door;

[0015] When the lifting door rises and opens the passage opening, the counterweight is located above the passage opening, and along the thickness direction of the mounting door frame, the lifting door and the counterweight are staggered.

[0016] In the present technical solution, a second stroke amplification mechanism is provided to establish a transmission connection between the counterweight and the lifting door, so that the lifting displacement of the counterweight can be smaller than the displacement required for the lifting door to open and close by utilizing the characteristics of the second stroke amplification mechanism to amplify the stroke. By reducing the lifting displacement of the counterweight, the counterweight can be installed in the installation door frame, and the lowering of the counterweight caused by the lifting door rising will not affect the normal passage of the passage. In addition, by staggering the lifting door and the counterweight along the thickness direction of the installation door frame to achieve a compact structure, the space occupied by the entire passage opening and closing device can be further reduced.

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

[0018] In this technical solution, a second movable pulley is provided on the counterweight, which helps to limit the range of movement of the counterweight and avoids the excessive range of movement interfering with the normal operation of the battery exchange equipment, making the movement of the counterweight more flexible in a limited space, which is suitable for occasions with limited moving areas.

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

[0020] In the technical solution, placing the connection end of the second stroke amplification mechanism on the central axis of the lift door can achieve balanced force transmission, help ensure the stable movement of the lift door during opening and closing, and reduce the uneven force and torque it is subjected to. In addition, it also helps prevent the lift door from deflecting or swinging during movement, thereby improving the reliability of movement.

[0021] Preferably, the counterweight and / or the linear drive mechanism are arranged on a side of the installation door frame facing the charging area.

[0022] In this technical solution, the linear drive mechanism and the counterweight are placed on one side of the charging area, that is, inside the battery swap station, which 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 to a certain extent improve the aesthetics of the battery swap station.

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

[0024] In the present technical solution, by setting the first movable pulley on the linear moving end of the linear drive mechanism in the first stroke amplification mechanism, the transmission chain can be transmitted along the moving direction of the linear moving end of the linear drive mechanism, so that the drive mechanism can operate in a limited space to ensure the normal movement of the lifting door.

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

[0028] In the technical solution, by adopting the first stroke amplification mechanism of this structural form, it is helpful to balance the movement of the lifting door, ensure that the lifting door remains stable during the lifting process, and reduce the vibration and swing caused by imbalance. In addition, the reasonable arrangement of the first steering wheel and the second steering wheel helps to guide the transmission chain to transmit in the required direction, ensuring that the transmission chain will 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 toward the passage opening, the buffer structure extends along the moving direction of the battery exchange device, and a receiving groove for receiving 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 the present technical solution, the in-position detection component is utilized to accurately detect whether the lifting door has moved to the preset position, and the position of the lifting door is timely sent to the linear drive mechanism in the form of a signal, so that the linear drive mechanism performs the next step according to the received signal. This design helps to ensure that the lifting door can accurately stop at the desired position, improve the opening and closing accuracy of the passage opening, thereby preventing the lifting door from excessive movement or inaccurate movement position, ensuring the safety performance of the passage opening opening and closing device, and avoiding the safety hazards caused by the lifting door staying in an incorrect position.

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

[0037] In this technical solution, the design of the slide rail and the slider helps to ensure that the lifting door maintains smooth movement during movement, improves the stability of the operation of the channel opening and closing device, and prevents the lifting door from deviating from or detaching from the installation door frame during movement.

[0038] A battery swap station, comprising a channel opening and closing device as described in any one of the above items.

[0039] 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.

[0040] The positive and progressive effects of the utility model are:

Further, a linear drive mechanism is set and the lifting door is driven to rise and fall 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 of the opening and closing of 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 rise and fall, 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 passage opening and closing device to be too high.

[0071] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0072] The utility model provides a battery swap station for providing battery swap services to vehicles entering the battery swap station, wherein the battery swap station includes a battery swap area and a charging area, the area for vehicles to enter is the battery swap area, and battery swap equipment is provided in the battery swap area to disassemble and assemble the batteries loaded on the vehicle. After the disassembly and assembly are completed, the battery swap equipment will enter the charging area through a passageway to charge the batteries removed from the vehicle. In order to separate the charging area from the battery swap area while not affecting the normal operation of the battery swap equipment, a passageway opening and closing device will also be provided at the passageway of the battery swap station.

[0073] like Figure 1-Figure 7 As shown, this embodiment provides a preferred structural setting scheme of a channel opening and closing device 100. The function of the channel opening and closing device 100 is to close and open the channel opening 11 of the battery swap station. The switching between the open state and the closed state is respectively as shown in FIG. Figure 1 and Figure 4 As shown, Figure 1 In the open state, Figure 4 The passage opening and closing device 100 specifically includes a lifting door 12, a mounting door frame 13, a linear drive mechanism 14, a first stroke amplification mechanism 15 and a reversing mechanism 17. The mounting door frame 13 surrounds the area where the passage opening 11 is located. The linear drive mechanism 14, the first stroke amplification mechanism 15 and the reversing mechanism 17 are all arranged in 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 passage opening 11 is opened. 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, 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 people and foreign objects from invading the charging area of ​​the battery swap station, and improve the isolation effect between the charging area and the outside world, meeting the requirements of dust prevention, heat preservation, etc. Of course, in other embodiments, the lifting door 12 can also half-cover or partially cover the passage opening 11 as needed, and the specific coverage degree can be set as needed according to actual needs.

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

[0082] In this embodiment, the linear drive mechanism 14 is extended 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 the amplified driving stroke through the amplification principle of the movable pulley.

[0083] At the same time, the passage opening and closing device 100 also includes a second stroke amplification mechanism 16. The second stroke amplification mechanism 16 and the counterweight 18 are both arranged in the mounting door frame 13, and the counterweight 18 is vertically 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 row of the lifting movement of the counterweight 18 to the fifth stroke of the lifting movement of the lifting door 12. By utilizing the stroke amplification characteristic of the second stroke amplification mechanism 16, the smaller displacement stroke of the counterweight 18 can drive the lifting door 12 to produce a larger displacement stroke, so that the lifting displacement size of the counterweight 18 can be smaller than the displacement required for the opening and closing of the lifting door 12.

[0084] Furthermore, when the lifting door 12 rises and opens the passage opening 11, the counterweight 18 is located above the passage opening 11. By reducing the lifting displacement of the counterweight 18, the counterweight 18 can be installed in the installation door frame 13, and the lowering of the counterweight 18 caused by the rising of the lifting door 12 will not affect the normal passage of the passage opening 11.

[0085] On this basis, this embodiment also provides a preferred arrangement scheme of the counterweight at the passage opening: Figure 7 As shown, along the thickness direction of the door frame 13, the lifting door 12 and the counterweight 18 are staggered left and right. Figure 7 As shown, the counterweight 18 is located on the left side of the figure, and the lifting door 12 is located on the right side of the figure. Therefore, when the counterweight 18 drives the lifting door 12 to move to the desired 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 normal opening and closing function of the lifting door 12 of the passage opening 11. In addition, by staggering the lifting door 12 and the counterweight 18 along the thickness direction of the installation door frame 13, the space in the installation door frame 13 is fully utilized to achieve a compact structure, so that the height space occupied by the entire passage opening and closing device 100 can be further reduced.

[0086] like Figure 1-Figure 6 As shown, the connection end of the second stroke amplification mechanism 16 and the lifting door 12 is arranged at the central axis of the lifting door 12, which can achieve balanced force transmission, help ensure the stable movement of the lifting door 12 during the opening and closing process, and reduce the uneven force and torque it is subjected to. In addition, it also helps to prevent the lifting door 12 from deflecting or swinging during the movement process, thereby improving the reliability of movement.

[0087] In this embodiment, the second stroke amplification mechanism 16 also realizes the stroke amplification function by means of a movable pulley, so the stroke amplification ratio is 1:2. The second stroke amplification mechanism 16 specifically includes a second movable pulley 161 arranged on the counterweight 18 and two fixed pulleys 162 arranged in parallel on the mounting door frame 13. The setting positions of the two fixed pulleys 162 are as shown in FIG. Figure 1 As shown, one of the fixed pulleys 162 is arranged on the mounting door frame 13 and located at the central axis of the lifting door 12, and the other fixed pulley 162 is arranged along the width direction of the mounting door frame 13 between the counterweight 18 and the connecting end of the second stroke amplification mechanism 16 and the lifting door 12.

[0088] One end of the transmission chain led out from the second movable pulley 161 of the second stroke amplifying mechanism 16 is arranged on the mounting door frame 13 , and the other end passes through two fixed pulleys 162 and is connected to the lifting door 12 .

[0089] In this embodiment, a second movable pulley 161 is provided on the counterweight 18 to utilize the principle of the movable pulley amplifying the stroke to prevent the counterweight 18 from moving too much, thereby preventing its movement range from being too large to interfere with the normal operation of the battery exchange equipment. This makes the movement of the counterweight 18 in a limited space more flexible, and is suitable for occasions where the moving area is limited.

[0090] Preferably, the counterweight 18 and the linear drive mechanism 14 are both arranged on the side of the mounting door frame 13 facing the charging area, that is, inside the battery swap station, which 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 to a certain extent improve the aesthetics of the battery swap station. Of course, in other embodiments, the counterweight 18 can also be arranged on the side facing the battery swap area, and the specific layout position can be adjusted as needed.

[0091] like Figure 1 As shown, the first stroke amplification mechanism 15 in this embodiment adopts the movable pulley principle to achieve the purpose of amplifying the stroke, and 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 by 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 setting 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 transmitted along the moving direction of the linear moving end of the linear drive mechanism 14, so that the drive mechanism can operate in a limited space to ensure the normal movement of the lifting door 12.

[0093] Furthermore, there are two transmission chains extending from the first movable pulley 151, and the reversing mechanism 17 also 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 mounting door frame 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 of the transmission chains passes through the first steering wheel 171 and 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 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, the first stroke amplification mechanism 15 of this structural form is used to help balance the movement of the lifting door 12, ensure that the lifting door 12 remains stable during the lifting process, and reduce vibration and swing caused by imbalance. In addition, the reasonable arrangement of the first steering wheel 171 and the second steering wheel 172 helps guide the transmission chain to transmit in the desired direction, ensuring that the transmission chain will not deviate from the direction during the power transmission process.

[0096] like Figure 3 and Figure 6 As shown, a buffer structure 19 is provided at the bottom end of the lifting door 12 along its moving direction and toward the passage opening 11. The buffer structure 19 is extended along the moving direction of the battery exchange equipment, and a receiving groove for accommodating the buffer structure 19 is provided on the ground (not shown in the figure). In the present embodiment, the buffer structure 19 is a plate-like structure and is extended from the bottom of the lifting door 12 toward the interior of the battery exchange station.

[0097] In this embodiment, the buffer structure 19 is mainly used to prevent the driver from opening the door and getting off the vehicle during the battery swap process, because during the battery swap process, the lift door 12 is in a state of opening the passage opening 11, and the buffer structure 19 is just opposite the door of the battery swap 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 12 closes the passage opening 11, thereby reducing the impact force, helping to protect the lift door 12 and related mechanical parts from excessive impact, reducing damage and extending the service life. In addition, by extending the buffer structure 19 along the moving direction of the battery swap equipment, the lift door 12 can be more smoothly in contact with the ground when closing the passage opening 11 by increasing the contact surface. 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 and helps to ensure that the buffer structure 19 can effectively play its role and remain in the appropriate position.

[0098] Preferably, there are multiple buffer structures 19 , and the multiple buffer structures 19 are arranged in sequence and spaced apart 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 Figure 1-Figure 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-position detection component 200 in this embodiment includes a touch arm 21 and a sensor 22. 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. When the lifting door 12 is about to open the passage opening 11 and rises 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 stop signal to the linear drive mechanism 14 through the sensor 22.

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

[0106] like Figure 1-Figure 6 As shown, slide rails 131 extending along the moving direction of the lifting door 12 for moving the lifting door 12 are provided on both sides of the installation door frame 13, and sliders 121 adapted to the slide rails 131 are provided on both sides of the lifting door 12. The sliders 121 and the slide rails 131 are adapted to each other, and preferably the sliders 121 are embedded in the slide rails 131. The lifting door 12 is moved on the installation door frame 13 by the sliders 121 along the extending direction of the slide rails 131.

[0107] In this embodiment, the design of the slide rail 131 and the slider 121 helps to ensure that the lifting door 12 maintains smooth movement during movement, improves the stability of the operation of the passage opening and closing device 100, and prevents the lifting door 12 from deviating from or detaching from the mounting door frame 13 during movement.

[0108] Preferably, the number of the sliders 121 on each side can be two, and they are arranged in pairs on both sides of the lifting door 12 to achieve multi-point connection with the lifting door 12 and effectively balance the force generated by the lifting door 12 during movement.

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

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.
