Description

Technical Field

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

[0002] In battery swap stations of the prior art, in order to ensure the safety of the charging area connected to the battery swap area, a channel opening and closing device is usually set at the connection point between the two (i.e., the channel for the battery swap shuttle vehicle to travel), and the channel opening and closing is achieved by driving the lifting door to rise and fall. Usually, in order to achieve the drive of the lifting door, a transmission assembly is usually set to achieve the connection between the lifting door and the counterweight block and the lifting drive mechanism. The transmission assembly specifically includes a wire rope and a guide wheel. The two ends of the wire rope are respectively connected to the lifting door and the counterweight block, as well as the lifting door and the drive mechanism. The guide wheel is for the wire rope to pass through to change the transmission direction of the wire rope. However, there is a potential problem with this design, that is, the wire rope is easy to fall off at the guide wheel during the transmission process, causing the entire transmission assembly to fail, making it difficult for the opening and closing mechanism of the channel opening to operate normally. At the same time, after the wire rope falls off, it may also cause the lifting door to fall from a height, posing a safety hazard.

[0003] Therefore, the problem of easy falling off of wire rope in transmission components needs to be paid attention to. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art that the steel wire rope of the channel opening and closing device is easy to fall off and there are safety hazards, and to provide a channel opening and closing device and a battery swap station including the same.

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

[0006] A passage opening and closing device, the passage opening and closing device comprising a passage opening for a battery exchange device to enter and exit a charging area, a mounting door frame, and a lifting door disposed on the mounting door frame and capable of opening and closing the passage opening, the passage opening opening and closing device further comprising:

[0007] A transmission mechanism, the transmission mechanism is arranged in the installation door frame, the transmission mechanism includes a plurality of transmission wires and a guide wheel, one end of the plurality of transmission wires is respectively connected to the lifting door, and the other end of the plurality of transmission wires is connected to the lifting drive mechanism or the counterweight mechanism of the passage opening and closing device after passing through the transmission surface of the guide wheel respectively, the surface of the guide wheel has roller grooves corresponding to the number of the transmission wires, and each of the roller grooves is arranged in parallel to accommodate the corresponding transmission wires respectively;

[0008] A limiting mechanism is provided on the guide wheel, and is used to limit the transmission wire from escaping from the roller groove.

[0009] In this technical solution, the transmission mechanism is provided with multiple transmission wires to connect with the lifting door by using the multiple transmission wires. Even if one of the transmission wires falls off from the guide wheel due to external factors, the remaining transmission wires can still maintain normal working conditions, enabling the lifting door to lift and lower normally and avoiding potential safety hazards caused by the falling of the lifting door. Further, a limiting mechanism is provided on the guide wheel of the transmission mechanism. Through the limiting mechanism, the transmission wire is transmitted at the correct position on the guide wheel to provide a second layer of protection, effectively reducing the possibility of the transmission wire disengaging from the guide wheel during transmission, helping to prevent problems such as the failure of the lifting door or unstable movement caused by the transmission wire disengaging from the guide wheel, ensuring the normal operation of the transmission mechanism, and thus guaranteeing the stable lifting and lowering of the lifting door.

[0010] Preferably, the guide wheel is connected to the installation door frame through a mounting bracket, and the guide wheel is rotatably arranged on the mounting bracket;

[0011] The limiting mechanism includes a first limiting member provided on the mounting bracket. The connection point of the first limiting member and the mounting bracket is located on the side where the guide wheel contacts the transmission wire. The first limiting member extends along the axis direction of the guide wheel on the surface of the mounting bracket and covers the outside of the roller groove;

[0012] And / or, the limiting mechanism includes a second limiting member provided on the mounting bracket. The connection point of the second limiting member and the mounting bracket is located on the side where the guide wheel does not contact the transmission wire. The second limiting member extends on the surface of the mounting bracket towards the side where the guide wheel contacts the transmission wire and covers the outside of the roller groove.

[0013] In this technical solution, the first limiting member and the second limiting member are arranged by using the mounting bracket that is connected to the guide wheel and relatively stationary to achieve the limiting of the transmission wire, avoiding problems such as difficult limiting caused by directly arranging the first limiting member and the second limiting member on the rotating guide wheel. Among them, the first limiting member is arranged on the surface of the mounting bracket and is arranged close to the position where the guide wheel contacts the transmission wire to prevent the transmission wire from disengaging from the roller groove through physical limiting, which can effectively restrict the movement of the transmission wire and keep the transmission wire in the correct position on the guide wheel. The second limiting member is arranged on the surface of the mounting bracket and is arranged at a position relatively far from the position where the guide wheel contacts the transmission wire. The second limiting member extends to the position where the guide wheel contacts the transmission wire by extending outwards to achieve the limiting of the transmission wire. The structural setting scheme of the second limiting member is applicable to the scheme where the lower surface of the guide wheel contacts the transmission wire, because usually in this structural layout, the mounting bracket is far from the contact position of the guide wheel and the transmission wire.

[0014] Preferably, a gap is formed between the first limiting member and / or the second limiting member and the outer edge of the guide wheel, and the size of the gap is smaller than the diameter of the transmission wire.

[0015] In this technical solution, by arranging the gap between the first limiting member and the second limiting member and the guide wheel, direct contact between the two is avoided, and friction and wear that may occur during the transmission of the guide wheel are reduced. At the same time, when the gap size between the two is controlled to be smaller than the diameter of the transmission wire, it also prevents the transmission wire from slipping out of the guide wheel from the gap, which helps to extend the service life of the transmission wire and the limiting mechanism, improves the durability of the limiting mechanism and the transmission mechanism, and improves the reliability and safety of the channel opening and closing device.

[0016] Preferably, the first limiting member and / or the second limiting member is a sheet-like structure formed by bending a sheet metal, and a receiving groove for receiving the first limiting member and / or the second limiting member is provided on the mounting bracket, and the first limiting member and / or the second limiting member is positioned and installed in the receiving groove in a snap-fit manner.

[0017] In this technical solution, the first limiting member and the second limiting member are designed in an insert-sheet type. Without the assistance of screws and nuts for locking, only by connecting with the mounting bracket in a snap-fit manner, not only simplifies the installation process of the first limiting member and the second limiting member, reduces the installation complexity, but also makes the structure compact and does not occupy too much other space.

[0018] Preferably, the first limiting member and / or the second limiting member is tangent to the surface of the guide wheel in the radial direction along the central axis of the guide wheel.

[0019] In this technical solution, by setting the first limiting member and the second limiting member to be tangent to the surface of the guide wheel, the transmission wire is maximally restricted to the correct position of the guide wheel.

[0020] Preferably, the transmission mechanism further includes a stroke amplification assembly, and the stroke amplification assembly is used to amplify the first displacement driven by the lifting drive mechanism or the counterweight mechanism and transmitted by the transmission wire into the second displacement driven by the transmission wire to drive the lifting door.

[0021] In this technical solution, by arranging a stroke amplification assembly in the transmission mechanism to amplify the displacement of the transmission wire driving the lifting door, the characteristic of amplifying the moving stroke is utilized so that the smaller moving stroke generated by the lifting drive mechanism or the counterweight mechanism can meet the displacement requirements for opening and closing the lifting door, and the movement amplitude of the lifting drive mechanism or the counterweight mechanism in the installation door frame is reduced, and the space occupation is reduced.

[0022] Preferably, the stroke amplification assembly includes a movable pulley set, the transmission wire is threaded through the movable pulley set, and the limiting mechanism is also arranged on the movable pulley set to limit the displacement of the transmission wire on the surface of the movable pulley set.

[0023] In this technical solution, the stroke amplification assembly uses a movable pulley set to achieve the function of stroke amplification, with a simple structure and high reliability. At the same time, by also arranging a limiting mechanism on the movable pulley set, the transmission wire is prevented from loosening from the surface of the movable pulley set.

[0024] Preferably, there are two transmission wires led out from the movable pulley, and the transmission mechanism further includes a commutation assembly. The commutation assembly includes a first steering wheel and a second steering wheel respectively arranged on both sides of the installation door frame;

[0025] One of the transmission wires passes through the first steering wheel and is connected to the top of the lifting door on the side where the first steering wheel is located;

[0026] The other transmission wire 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.

[0027] 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 vibration and swing caused by imbalance. Moreover, the reasonable setting of the first steering wheel and the second steering wheel helps to guide the transmission wire to be transmitted along the required direction, ensuring that the transmission wire does not deviate from the direction during the power transmission process.

[0028] Preferably, the passage opening and closing device further includes a transmission wire adjusting mechanism. Multiple transmission wires are connected to the lifting door through the transmission wire adjusting mechanism, and the transmission wire adjusting mechanism is used to adjust the lengths of the connected transmission wires.

[0029] In this technical solution, a transmission wire adjusting mechanism is provided to realize the connection between the transmission wire and the lifting door, and the lengths of the transmission wires are adjusted through the transmission wire adjusting mechanism. In the case of connecting the lifting door by using multiple transmission wires, by adjusting the lengths of the transmission wires, the influence of different lengths of the transmission wires on the transmission efficiency is avoided, meeting the requirement for the stable lifting of the lifting door.

[0030] Preferably, the transmission wire adjusting mechanism includes:

[0031] Two clamping members arranged oppositely, the two clamping members are respectively connected to the lifting door, and the two transmission wires are arranged in parallel between the two clamping members;

[0032] A locking member is provided on the clamping member, and the locking member is used to drive the two clamping members to approach each other relatively to fix the transmission wire between the two clamping members.

[0033] In this technical solution, by setting the locking member to clamp the clamping member, the connection of multiple transmission wires is achieved by the acting force of the two clamping members approaching each other relatively. By unlocking the locking member, the clamping force of the two clamping members on the transmission wire can be released, so that the position of the transmission wire relative to the clamping member can be adjusted to achieve the purpose of adjusting the length of the transmission wire.

[0034] Preferably, an arc-shaped flanging is provided at the edge of the surface of the clamping member in contact with the transmission wire;

[0035] The number of the locking members is three, and the three locking members and the two transmission wires are alternately arranged on the clamping member;

[0036] The locking member is a screw, and the screw is threadedly connected to a threaded hole provided on the other clamping member after passing through a through hole provided on one of the clamping members.

[0037] In this technical solution, by providing an arc-shaped flanging at the edge of the surface of the clamping member in contact with the transmission wire, it is avoided that during the clamping process, the corner structure at the edge of the clamping member presses the transmission wire and causes damage to the transmission wire. At the same time, setting the arc-shaped flanging also reduces the frictional force between the transmission wire and the clamping member when adjusting the length, which helps to extend the service life of the transmission wire and reduce the maintenance frequency.

[0038] Secondly, three locking members and two transmission wires are alternately arranged so that the transmission wire adjusting mechanism can adjust the other transmission wire when clamping one transmission wire. Specifically, by unlocking the locking members located on both sides of the corresponding transmission wire, the transmission wire can be adjusted relative to the clamping member, while the other transmission wire remains fixed to the clamping member due to the action of the remaining unlocked locking member. Therefore, through this technical solution, when the length of the transmission wire on one side needs to be adjusted, the unlocked locking member can keep the transmission wire on the other side fixed, realizing single-sided adjustment, which is beneficial to improving the stability when multiple transmission wires drive the lifting door to move.

[0039] Finally, the function of the locking member is realized through a relatively simple structure, which is convenient for processing and maintenance.

[0040] A swapping station includes the channel opening and closing device described in any one of the above.

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

[0042] The positive and progressive effects of the present invention are as follows:

[0043] 1. In the channel opening and closing device, the transmission mechanism is provided with multiple transmission wires to connect with the lifting door by using the multiple transmission wires. Even if one of the transmission wires falls off from the guide wheel due to external factors, the remaining transmission wires can still maintain normal working conditions, enabling the lifting door to lift and lower normally and avoiding potential safety hazards caused by the dropping of the lifting door. Further, a limiting mechanism is provided on the guide wheel of the transmission mechanism, which enables the transmission wire to be transmitted at the correct position of the guide wheel to provide a second layer of protection, effectively reducing the possibility of the transmission wire disengaging from the guide wheel during transmission, helping to prevent problems such as the failure of the lifting door or unstable movement caused by the transmission wire disengaging from the guide wheel, ensuring the normal operation of the transmission mechanism, and thus guaranteeing the stable lifting and lowering of the lifting door.

[0044] 2. The battery swapping station with the channel opening and closing device adopting the above structural form can effectively control the opening and closing of the channel in the battery swapping station, provide a flexible operation channel for the battery swapping equipment, and realize safe and orderly battery swapping services.

[0079] The present invention will be further described below by way of examples, but the present invention is not limited to the scope of the examples accordingly.

[0080] 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 11 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 100 is also provided at the position of the passage opening 11 of the battery swapping station.

[0081] As Figures 1 - 5 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. As Figure 1 shown, it is a schematic diagram of the state when the lifting door 13 of the passage opening opening and closing device 100 is at the lowest point to close the passage opening 11. Among them, the passage opening opening and closing device 100 specifically further includes a transmission mechanism 200, a limit mechanism 300, a lifting drive mechanism 400, and a counterweight mechanism 500.

[0082] The lifting drive mechanism 400 is specifically an electric push rod in this embodiment. By transmitting the displacement and driving force generated by the telescopic movement of the electric push rod to the lifting door 13, the lifting door 13 can rise to open the passage opening 11. And the counterweight mechanism 500 is specifically a counterweight block in this embodiment. By transmitting its weight to the lifting door 13, the gravity of the lifting door 13 is balanced, so that the electric push rod only needs a relatively small load to drive the lifting door 13. It can be seen from the figure that both the lifting drive mechanism 400 and the counterweight mechanism 500 are located above the lifting door 13, and the two are connected and transmitted to the lifting door through their respective transmission mechanisms 200.

[0083] Specifically, the transmission mechanisms 200 for realizing the transmission between the lifting drive mechanism 400 and the lifting door 13, and for realizing the transmission between the counterweight mechanism 500 and the lifting door 13 are all arranged in the installation door frame 12.

[0084] Taking the transmission mechanism 200 for realizing the transmission between the lifting drive mechanism 400 and the lifting door 13 as an example, this transmission mechanism 200 includes a plurality of transmission wires 23 and guide wheels 21. One ends of the plurality of transmission wires 23 are respectively connected to the lifting door 13, and the other ends of the plurality of transmission wires 23 are connected to the lifting drive mechanism 400 of the passage opening opening and closing device 100 after passing through the transmission surfaces of the guide wheels 21 respectively. And roller grooves 211 corresponding to the number of transmission wires 23 are provided on the surface of the guide wheel 21, and the roller grooves 211 are arranged in parallel for respectively accommodating the corresponding transmission wires 23.

[0085] Meanwhile, the limiting mechanism 300 is arranged on the guiding wheel 21 to limit the transmission wire 23 from disengaging from the roller groove 211.

[0086] In this embodiment, the transmission mechanism 200 is provided with multiple transmission wires 23 to connect with the lifting door 13 by using the multiple transmission wires 23. Even if one of the transmission wires 23 falls off from the guiding wheel 21 due to external factors, the remaining transmission wires 23 can still maintain a normal working state, enabling the lifting door 13 to lift and lower normally and avoiding potential safety hazards caused by the dropping of the lifting door 13.

[0087] Furthermore, by arranging the limiting mechanism 300 on the guiding wheel 21 of the transmission mechanism 200, the transmission wire 23 is made to transmit at the correct position on the guiding wheel 21 through the limiting mechanism 300, providing a second layer of protection, effectively reducing the possibility of the transmission wire 23 disengaging from the guiding wheel 21 during transmission, helping to prevent problems such as the failure of the lifting door 13 or unstable movement caused by the disengagement of the transmission wire 23 from the guiding wheel 21, ensuring the normal operation of the transmission mechanism 200, and thus enabling the smooth ascent and descent of the lifting door 13 under the drive of the lifting drive mechanism 400.

[0088] It should be clearly stated that in this embodiment, as Figure 1 shown, when the lifting door 13 is in the closed state, it completely covers the passage opening 11, effectively preventing 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 requirements such as dust prevention and heat preservation. Of course, in other embodiments, the lifting door 13 can also semi-cover or partially cover the passage opening 11 as needed, and the specific covering degree can be set according to actual requirements.

[0089] As Figures 3 - 4 shown, further, the guiding wheel 21 is connected to the inside of the installation doorframe 12 through the mounting bracket 22, and the guiding wheel 21 is rotatably arranged on the mounting bracket 22 for transmitting the transmission wire 23.

[0090] Among them, the limiting mechanism 300 includes a first limiting member 31 and a second limiting member 32 to limit different guiding wheels through different limiting methods. Specifically, as Figure 3 shown, at the edge position of the installation doorframe 12, the limiting mechanism 300 includes a first limiting member 31 arranged on the mounting bracket 22. The connection point of the first limiting member 31 and the mounting bracket 22 is located on the side where the guiding wheel 21 contacts the transmission wire 23, and the first limiting member 31 extends along the axis direction of the guiding wheel 21 on the surface of the mounting bracket 22 and covers the outside of the roller groove 211.

[0091] Meanwhile, as Figure 4As shown, at the top center position of the door frame 12, a guide wheel 21 is also arranged on another mounting frame 22, but the contact point between the guide wheel 21 and the transmission wire 23 is located at the bottom, and the mounting frame 22 is located above the guide wheel 21. Therefore, the connection point between the second limiting member 32 and the mounting frame 22 is located on the side where the guide wheel 21 and the transmission wire 23 are not in contact (i.e., the upper side of the guide wheel 21). The second limiting member 32 extends on the surface of the mounting frame 22 toward the side where the guide wheel 21 and the transmission wire 23 are in contact (i.e., the lower side of the guide wheel 21), and covers the outer side of the roller groove 211, thereby limiting the transmission wire 23 through the end of the second limiting member 32.

[0092] Therefore, in this solution, the first limiter 31 and the second limiter 32 are arranged by using the mounting frame 22 connected to the guide wheel 21 and relatively stationary, so as to avoid the problems such as difficulty in limiting caused by directly setting the first limiter 31 and the second limiter 32 on the rotating guide wheel 21. Among them, the first limiter 31 is arranged on the surface of the mounting frame 22 and is arranged near the position where the guide wheel 21 contacts the transmission wire 23, so as to prevent the transmission wire 23 from being separated from the roller groove 211 by physical limiting, and can effectively limit the movement of the transmission wire 23 and keep the transmission wire 23 in the correct position on the guide wheel 21. The second limiter 32 is arranged on the surface of the mounting frame 22 and is arranged at a position relatively far away from the contact between the guide wheel 21 and the transmission wire 23. The second limiter 32 extends to the position where the guide wheel 21 contacts the transmission wire 23 by extending outward, so as to limit the transmission wire 23. The structural setting scheme of the second limiter 32 is suitable for the scheme where the lower surface of the guide wheel 21 contacts the transmission wire 23. Furthermore, gaps are formed between the first limiting member 31 and the second limiting member 32 and the outer edge of the guide wheel 21 , and the size of the gaps is smaller than the diameter of the transmission wire 23 .

[0093] In this embodiment, by arranging a gap between the first limiter 31 and the second limiter 32 and the guide wheel 21, direct contact between the two is avoided, and the friction and wear of the guide wheel 21 that may occur during the transmission process is reduced. At the same time, the gap size between the two is controlled to be smaller than the diameter of the transmission wire 23, which prevents the transmission wire 23 from slipping out of the guide wheel 21 from the gap, helps to extend the service life of the transmission wire and the limiter mechanism 300, improves the durability of the limiter mechanism 300 and the transmission mechanism 200, and improves the reliability and safety of the channel opening and closing device 100.

[0094] In general, according to the different contact positions between the guide wheel 21 and the transmission wire 23, position limiting members with different structural shapes are provided to solve the transmission wire limiting problem on each guide wheel according to the actual structural layout.

[0095] Specifically, for these first limit members 31 and second limit members 32, the extension length along the axis direction of the guide wheel 21 should be greater than or equal to the diameter of the transmission wire 23.

[0096] In this embodiment, both the first limit member 31 and the second limit member 32 are sheet-like structures formed by bending a sheet metal, and there are receiving grooves on the mounting bracket 22 for receiving these limit members. Therefore, the first limit member 31 and the second limit member 32 can be positioned and installed in the receiving grooves in a snap-fit manner to achieve quick connection and reliable fixation. In addition, bonding methods such as nail-free glue can also be used to bond the first limit member 31 and the second limit member 32 to the mounting bracket 22 to enhance the stability of the first limit member 31 provided on the guide wheel 21.

[0097] In other embodiments, the limit member structure for limiting the position of the transmission wire can also be realized by using an anti-disengagement cover. Specifically, the anti-disengagement cover is arranged on the mounting bracket and partially wraps the guide wheel to limit the transmission wire within the range of the guide wheel without affecting the transmission of the transmission wire. However, compared with the structures of the first limit member 31 and the second limit member 32 provided in this embodiment, the anti-disengagement cover is larger in size, heavier in weight, and difficult to disassemble and assemble relative to the guide wheel, which is not conducive to maintenance.

[0098] It should be noted that although the structures of the first limit member 31 and the second limit member 32 provided in this embodiment are simple and convenient for installation, due to the small contact area with the transmission wire 23, there are certain limitations in terms of anti-disengagement reliability. However, combined with the solution of simultaneously leading out two transmission wires 23 for transmission in this embodiment, even if one of the transmission wires 23 accidentally falls off, the other transmission wire 23 can still continue to complete the work. Therefore, the solution of this embodiment selects the first limit member 31 and the second limit member 32 to limit the guide wheel 21, which is a solution obtained after comprehensively considering the operation reliability and the installation and maintenance difficulty. By combining the structures of the first limit member 31 and the second limit member 32 with the solution of using multiple transmission wires 23 for synchronous transmission, the installation and maintenance difficulty is reduced as much as possible on the premise of meeting the operation reliability.

[0099] In this embodiment, to further simplify the installation, the first limit member 31 and the second limit member 32 are designed in an insert-tab type, without the assistance of screws and nuts for locking. Only by connecting with the mounting bracket 22 in a snap-fit manner, not only makes the installation process of the first limit member 31 and the second limit member 32 more simplified, reduces the complexity of installation, but also makes the structure compact and does not occupy too much other space.

[0100] From Figure 3 and Figure 4It can be seen that the first limit member 31 and the second limit member 32 are arranged tangentially to the surface of the guide wheel 21 in the radial direction along the central axis of the guide wheel 21, so that the transmission wire 23 can be restricted to the correct position of the guide wheel 21 to the maximum extent.

[0101] In addition, along the height direction of the passage opening 11, the first limiting member 31 is arranged above the mounting frame 22 relative to the guide wheel 21. By arranging the first limiting member 31 above the pulley, the effective range of its limiting force is increased, making the limiting effect better and more stable.

[0102] like Figure 1 As shown, the transmission mechanism 200 further includes a stroke amplification component 24, which includes a first stroke amplification part 241 and a second stroke amplification part 242, which correspond to the driving mechanism 400 and the counterweight mechanism 500 respectively, so as to amplify the driving stroke, so that the driving mechanism 400 and the counterweight mechanism 500 can drive the lifting door 13 to a larger position through a smaller displacement. Specifically, the lifting driving mechanism 400 is connected to the lifting door 13 through the first stroke amplification part 241, and the counterweight mechanism 500 is connected to the lifting door 13 through the second stroke amplification part 242.

[0103] In this embodiment, a stroke amplification component 24 is provided in the transmission mechanism 200 to amplify the displacement of the lifting door 13 driven by the transmission wire 23, and the characteristic of amplifying the moving stroke is utilized so that the smaller moving stroke generated by the lifting drive mechanism 400 or the counterweight mechanism 500 can meet the displacement requirements of opening and closing the lifting door 13, thereby reducing the movement amplitude of the lifting drive mechanism 400 or the counterweight mechanism 500 in the installation door frame 12 and reducing space occupancy.

[0104] Here, the first stroke amplifying portion 241 connected to the lifting drive mechanism 400 is taken as an example to specifically illustrate the relevant structural scheme. Figure 3 As shown, the first stroke amplifying part 241 is a movable pulley group, and the transmission wire 23 is arranged in the movable pulley group. The stroke is amplified by the principle of the movable pulley. Therefore, in this embodiment, the stroke amplification ratio of the first stroke amplifying part 241 is 1:2. At the same time, the limiting mechanism 300 (specifically the first limiting member 31) is also arranged on the movable pulley group to limit the displacement of the transmission wire 23 on the surface of the movable pulley group to prevent the transmission wire 23 from accidentally falling out.

[0105] In this embodiment, the stroke amplification assembly 24 uses a movable pulley block to achieve the function of stroke amplification, with a simple structure and high reliability. At the same time, by also arranging a limit mechanism 300 on the movable pulley block, the transmission wire 23 is prevented from loosening from the surface of the movable pulley block. Of course, in other embodiments, other structural setting schemes capable of amplifying the stroke can also be used to achieve, such as a lever structure, etc. Compared with these structural schemes capable of amplifying the stroke, the first stroke amplification part 241 of the stroke amplification assembly 24 in this embodiment uses a movable pulley block to amplify the stroke. Although the amplification ratio is fixed at 1:2, the structure is simple and the reliability is high, fully meeting the operating reliability requirements of the lifting door 13 in this solution during the high-frequency lifting process. In addition, the second stroke amplification part 242 of the stroke amplification assembly 24 in this embodiment also uses a movable pulley block structure to achieve the transmission connection and stroke amplification between the counterweight mechanism 500 and the lifting door 13. The specific structural layout can refer to Figure 1 and is substantially the same as the structure of the first stroke amplification part 241, so it will not be elaborated here.

[0106] As Figure 1 shown, at the position of the cross beam at the upper end of the installation door frame 12 along the height direction of the passage opening 11, there is a track 121 extending along the moving direction of the lifting door 13. The track 121 is arranged on both sides of the counterweight mechanism 500 to provide guidance for the lifting movement of the counterweight mechanism 500.

[0107] In this embodiment, the setting of the track 121 helps to provide guidance for the movement of the counterweight mechanism 500, ensuring that it moves along the designed trajectory, helping to maintain the smooth movement of the lifting door 13, and reducing the swing and deviation during the movement process.

[0108] Preferably, along the height direction of the passage opening 11, the lower end of the track 121 has a horizontally extending limiting part 122, and the limiting part 122 is used to contact the lower surface of the counterweight mechanism 500 to limit the moving stroke of the counterweight mechanism 500.

[0109] In this embodiment, the setting of the limiting part 122 can effectively limit the moving range of the counterweight mechanism 500, ensuring that its movement on the track 121 is precisely controlled, preventing the counterweight mechanism 500 from exceeding the designed safety range during the movement of the lifting door 13 and interfering with the normal passage of the battery swapping equipment in the passage opening 11, and helping to avoid potential damage or safety risks.

[0110] In addition, as Figure 2As shown, along the thickness direction of the installation door frame 12, the lifting door 13 and the counterweight mechanism 500 are arranged in a staggered manner. Specifically, when the counterweight mechanism 500 drives the lifting door 13 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 13 and the counterweight mechanism 500 do not interfere with each other, and it will not affect the normal opening and closing function of the lifting door 13 for the passage opening 11. Moreover, by arranging the lifting door 13 and the counterweight mechanism 500 in a staggered manner along the thickness direction of the installation door frame 12, the space inside the installation door frame 12 can be fully utilized to achieve a compact layout of the structure, so that the space occupied by the entire passage opening opening and closing device 100 can be further reduced.

[0111] As Figure 1 and Figure 3 shown, the transmission mechanism 200 further includes a commutation assembly 25. The first stroke amplification portion 241 includes a first movable pulley 2411. The commutation assembly 25 includes a first steering wheel 251. The movable end of the lifting drive mechanism 400, that is, the output end of the lifting drive mechanism 400, is connected to the first movable pulley 2411. The transmission wire 23 led out from the first movable pulley 2411 passes through the first steering wheel 251 and then is connected to the top of the lifting door 13.

[0112] In this embodiment, by arranging the first movable pulley 2411 on the movable end of the lifting drive mechanism 400 in the first stroke amplification portion 241, the transmission wire 23 can be transmitted along the moving direction of the movable end of the lifting drive mechanism 400, so that the lifting drive mechanism 400 can operate in a limited space to ensure the normal movement of the lifting door 13.

[0113] Specifically, there are two transmission wires 23 led out from the first movable pulley 2411, and the commutation assembly 25 further includes a second steering wheel 252. The first steering wheel 251 and the second steering wheel 252 are respectively arranged on both sides of the installation door frame 12, that is, the first steering wheel 251 and the second steering wheel 252 are respectively located above the lifting door 13 and on both sides of the lifting door 13. Among the two transmission wires 23 led out from the first movable pulley 2411, one transmission wire 23 passes through the first steering wheel 251 and then is connected to the top of the lifting door 13 on the side where the first steering wheel 251 is located, and the other transmission wire 23 passes through the first steering wheel 251 and the second steering wheel 252 on the other side in sequence and then is connected to the top of the lifting door 13 on the side where the second steering wheel 252 is located.

[0114] In this embodiment, the transmission wire 23 is respectively connected to the left and right ends of the lifting door 13, which helps to balance the movement of the lifting door 13, ensures that the lifting door 13 remains stable during the lifting process, and reduces vibration and swing caused by imbalance. Moreover, the reasonable setting of the first steering wheel 251 and the second steering wheel 252 helps to guide the transmission wire 23 to transmit along the required direction, ensuring that the transmission wire 23 does not deviate from the direction during the power transmission process.

[0115] In addition, a guiding wheel 253 is also provided on the installation door frame 12 and between the first steering wheel 251 and the second steering wheel 252. The transmission wire 23 passes through the guiding wheel 253 after passing through the first steering wheel 251 and before passing through the second steering wheel 252 and is located at the bottom end on the side of the guiding wheel 253 facing the lifting door 13.

[0116] Therefore, in this embodiment, the second limiting member 32 is arranged on the mounting bracket 22 of the guiding wheel 253, and the second limiting member 32 is in a bent structure. The bent structure is a section that extends along the height direction of the channel opening 11 towards the side of the lifting door 13 and extends to the bottom end on the side of the guiding wheel 253 facing the lifting door 13, and the other section extends along the axial direction of the guiding wheel 253 and the extending length is not less than the diameter of the transmission wire 23 and there is a gap between it and the transmission wire 23.

[0117] In this embodiment, the setting of the guiding wheel 253 helps to guide the transmission wire to move along the correct track, can ensure that the transmission wire passes along the predetermined path, thereby ensuring the normal operation of the lifting door 13. Moreover, by arranging the second limiting member 32 at the guiding wheel 253 and setting it in a bent structure, it can effectively surround the transmission wire 23 transmitting at the bottom end of the guiding wheel 253, avoiding the possibility that the transmission wire 23 detaches from the guiding wheel 253 and falls off, ensuring that the transmission wire 23 moves along the correct track, and enhancing the stability of the transmission wire 23 transmitting at the bottom end of the guiding wheel 253.

[0118] In addition, along the height direction of the channel opening 11, when the second limiting member 32 extends towards the side of the lifting door 13, the extending length is greater than the height of the lifting drive mechanism 400. Adopting this structural form ensures that the transmission wire 23 will not collide with the drive mechanism in the height direction, prevents interference between the transmission wire 23 and the lifting drive mechanism 400, and reduces the risk of damage to the drive mechanism and / or the transmission wire 23.

[0119] Such as Figure 1 and Figure 5As shown, the channel opening and closing device 100 further includes a transmission wire adjusting mechanism 600. The transmission wire adjusting mechanism 600 is arranged on both sides of the top of the lifting door 13. For any one side, there are two transmission wires 23 connected to the lifting door 13 through the transmission wire adjusting mechanism 600. The transmission wire adjusting mechanism 600 is used to adjust the lengths of the connected transmission wires 23. In the case of connecting the lifting door 13 by using multiple transmission wires 23, by adjusting the lengths of the transmission wires 23, the influence of different lengths between the transmission wires 23 on the transmission efficiency can be avoided, and the smooth lifting requirement of the lifting door 13 can be met.

[0120] In this embodiment, the transmission wire adjusting mechanisms 600 are arranged on both the left and right sides of the lifting door 13. In other embodiments, the arrangement position and quantity of the transmission wire adjusting mechanisms 600 can be adjusted as required. As Figure 5 shown, this embodiment further provides a preferred structural setting scheme of the transmission wire adjusting mechanism 600 to facilitate the adjustment of the connection lengths between the transmission wires 23 and the lifting door 13. The transmission wire adjusting mechanism 600 includes two clamping members 61, a locking member 62 and a base 63.

[0121] Among them, the two clamping members 61 are arranged oppositely and are respectively connected to the lifting door 13, and the two transmission wires 23 are arranged in parallel between the two clamping members 61. The locking member 62 is arranged through the clamping members 61 to drive the two clamping members 61 to approach relatively to fix the transmission wires 23 between the two clamping members 61.

[0122] Preferably, Figure 5 the clamping member 61 on the right side in [[ ]] is fixedly arranged on the lifting door 13 through the base 63, and the clamping member 61 on the left side is movably connected to the clamping end of the clamping member 61 on the right side through the locking member 62. In this way, when adjusting the transmission wires 23, only the clamping member 61 on the left side needs to be loosened for adjustment, which improves the operation convenience.

[0123] Therefore, in this embodiment, by setting the locking member 62 to clamp the clamping members 61, the connection of multiple transmission wires 23 is realized by the acting force of the two clamping members 61 approaching relatively. By unlocking the locking member 62, the clamping force of the two clamping members 61 on the transmission wires 23 can be released, so that the position of the transmission wires 23 relative to the clamping members 61 can be adjusted, and the purpose of adjusting the lengths of the transmission wires 23 can be achieved.

[0124] As Figure 5As shown, an arc flanging is provided at the surface edge of the clamping member 61 in contact with the transmission wire 23 to prevent the corner structure at the edge of the clamping member 61 from pressing the transmission wire 23 during the clamping process, resulting in damage to the transmission wire 23. At the same time, the provision of the arc flanging also reduces the frictional force between the transmission wire 23 and the clamping member 61 when adjusting the length, which helps to extend the service life of the transmission wire 23 and reduce the maintenance frequency.

[0125] Moreover, the number of the locking members 62 is three, and the three locking members 62 and the two transmission wires 23 are alternately arranged on the clamping member 61, so that the transmission wire adjusting mechanism 600 can adjust the other transmission wire 23 when clamping one of the transmission wires 23. Specifically, by unlocking the locking members 62 located on both sides of the corresponding transmission wire 23, the transmission wire 23 can be adjusted relative to the clamping member 61, while the other transmission wire 23 remains fixed to the clamping member 61 due to the action of the remaining one unlocked locking member 62. Therefore, through this technical solution, when the length of one side of the transmission wire 23 needs to be adjusted, the unlocked locking member 62 can keep the other side of the transmission wire 23 fixed, realizing single-sided adjustment, which is beneficial to improving the stability when the multiple transmission wires 23 drive the lifting door 13 to move.

[0126] In addition, the locking member 62 is a screw, and the screw is threadedly connected to the threaded hole provided on the other clamping member 61 after passing through the through hole provided on one of the clamping members 61, realizing the function of the locking member 62 through a relatively simple structure, which is convenient for processing and beneficial to maintenance.

[0127] The channel opening and closing device 100 in this embodiment is applied in a battery swapping station to realize the opening and closing of the channel opening 11 of the battery swapping station. However, in other embodiments, the channel 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 channel opening 11.

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