Description

Technical Field

[0001] The utility model 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 comprising 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. Utility Model Content

[0004] The technical problem to be solved by the utility model 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 utility model solves the above technical problems through the following technical solutions:

[0006] A passage opening and closing device, the passage opening and closing device comprising a passage opening for a battery 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 the present technical solution, the transmission mechanism is provided with multiple transmission wires to realize the connection with the lifting door by using multiple transmission wires, so that even if one of the transmission wires falls off from the guide wheel due to external factors, the remaining transmission wires can still maintain a normal working state, so that the lifting door can be lifted and lowered normally, avoiding the safety hazard caused by the lifting door falling. Further, by providing a limiting mechanism on the guide wheel of the transmission mechanism, the transmission wire is transmitted at the correct position of the guide wheel through the limiting mechanism to provide a second guarantee, effectively reducing the possibility of the transmission wire being separated from the guide wheel during the transmission process, helping to prevent the failure of the lifting door or unstable movement caused by the transmission wire being separated from the guide wheel, ensuring the normal operation of the transmission mechanism, and thus ensuring the smooth lifting and lowering of the lifting door.

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

[0011] The limiting mechanism comprises a first limiting member arranged on the mounting frame, the connection point between the first limiting member and the mounting frame is located at a side where the guide wheel contacts the transmission wire, and the first limiting member extends on the surface of the mounting frame along the axis direction of the guide wheel and covers the outer side of the roller groove;

[0012] And / or, the limiting mechanism includes a second limiting member arranged on the mounting frame, the connection point between the second limiting member and the mounting frame is located on the side where the guide wheel and the transmission wire are not in contact, and the second limiting member extends on the surface of the mounting frame toward the side where the guide wheel and the transmission wire are in contact and covers the outer side of the roller groove.

[0013] In the present technical solution, a first limiter and a second limiter are arranged by using a mounting frame connected to a guide wheel and relatively stationary, so as to achieve the limitation of the transmission wire, and avoid the limitation difficulties caused by directly setting the first limiter and the second limiter on the rotating guide wheel. Among them, the first limiter is arranged on the surface of the mounting frame and is arranged near the position where the guide wheel contacts the transmission wire, so as to prevent the transmission wire from being separated from the roller groove by physical limitation, and can effectively limit the movement of the transmission wire and keep the transmission wire in the correct position on the guide wheel. The second limiter is arranged on the surface of the mounting frame and is arranged relatively far away from the position where the guide wheel contacts the transmission wire. The second limiter extends to the position where the guide wheel contacts the transmission wire by extending outward, so as to achieve the limitation of the transmission wire. The structural setting scheme of the second limiter is suitable for the scheme where the lower surface of the guide wheel contacts the transmission wire, because usually under this structural layout, the mounting frame is far away from the contact position between 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 the technical solution, by arranging the gap between the first limiter and the second limiter and the guide wheel, direct contact between the two is avoided, and the friction and wear of the guide wheel 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, which is better than avoiding the transmission wire from escaping from the guide wheel through the gap, which helps to extend the service life of the transmission wire and the limit mechanism, improve the durability of the limit mechanism and the transmission mechanism, and improve the reliability and safety of the channel opening and closing device.

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

[0017] In the present technical solution, the first limit member and the second limit member are designed with a plug-in type, which does not require screws and nuts to assist in locking, and only needs to be connected by snapping with the mounting frame. This not only simplifies the installation process of the first limit member and the second limit member and reduces the complexity of installation, 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 are arranged tangentially to the surface of the guide wheel in the radial direction along the central axis of the guide wheel.

[0019] In the present technical solution, the first limiting member and the second limiting member are designed to be tangent to the surface of the guide wheel, so as to maximize the restriction of the transmission wire to the correct position of the guide wheel.

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

[0021] In the present technical solution, a stroke amplification component is provided in the transmission mechanism to amplify the displacement of the lifting door driven by the transmission belt, and the characteristic of the amplified 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 of the opening and closing of the lifting door, thereby reducing the movement amplitude of the lifting drive mechanism or the counterweight mechanism in the installation door frame and reducing the space occupied.

[0022] Preferably, the stroke amplification component includes a movable pulley block, the transmission wire is inserted into the movable pulley block, and the limiting mechanism is also arranged on the movable pulley block to limit the displacement of the transmission wire on the surface of the movable pulley block.

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

[0024] Preferably, there are two transmission wires led out from the movable pulley, and the transmission mechanism further includes a reversing assembly, and the reversing assembly includes a first steering wheel and a second steering wheel respectively arranged on both sides of the mounting 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] Another 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 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 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 wire to transmit in the required direction, ensuring that the transmission wire will not deviate from the direction during the power transmission process.

[0028] Preferably, the passage opening and closing device further comprises a transmission wire adjustment mechanism, and a plurality of the transmission wires are connected to the lifting door via the transmission wire adjustment mechanism, and the transmission wire adjustment mechanism is used to adjust the length of each of the connected transmission wires.

[0029] In the present technical solution, a transmission wire adjustment mechanism is provided to realize the connection between the transmission wire and the lifting door, and the length of each transmission wire is adjusted by the transmission wire adjustment mechanism. When the lifting door is connected by utilizing multiple transmission wires, the length of the transmission wire can be adjusted to avoid the different lengths of the transmission wires affecting the transmission efficiency, thereby meeting the requirement for smooth lifting of the lifting door.

[0030] Preferably, the transmission wire adjustment mechanism comprises:

[0031] Two clamping members are arranged opposite to each other, 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 arranged on the clamping member, and is used to drive the two clamping members to be relatively close to each other so as to fix the transmission wire between the two clamping members.

[0033] In the technical solution, by setting a locking member to clamp the clamping member, the force of the two clamping members being relatively close to each other is used to achieve the connection of multiple transmission wires. 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, thereby achieving the purpose of adjusting the length of the transmission wire.

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

[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 after passing through a through hole provided on one of the clamping members, the screw is threadedly connected with a threaded hole provided on the other clamping member.

[0037] In this technical solution, an arc-shaped flange is provided on the edge of the surface where the clamping member contacts the transmission wire, so as to avoid the corner structure at the edge of the clamping member pressing the transmission wire during the clamping process, thereby preventing the transmission wire from being damaged. At the same time, the arc-shaped flange also reduces the friction 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 pieces are arranged alternately with two transmission wires, so that the transmission wire adjustment mechanism can adjust the other transmission wire when one of the transmission wires is clamped. Specifically, by unlocking the locking pieces on both sides of the corresponding transmission wire, the transmission wire can be adjusted relative to the clamping piece, while the other transmission wire remains fixed in position with the clamping piece due to the action of the remaining unlocked locking piece. Therefore, through this technical solution, when the transmission wire on one side needs to adjust its length, the unlocked locking piece can keep the transmission wire on the other side fixed, realizing unilateral adjustment, which is conducive to improving the stability of the lifting door when multiple transmission wires drive it to move.

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

[0040] A battery swap station, comprising a channel opening and closing device as described in any one of the above items.

[0041] 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.

[0042] The positive and progressive effects of the utility model are:

[0043] 1. In the passage opening and closing device, the transmission mechanism is provided with multiple transmission wires to realize the connection with the lifting door by using multiple transmission wires, so that even if one of the transmission wires falls off from the guide wheel due to external factors, the remaining transmission wires can still maintain a normal working state, so that the lifting door can be lifted and lowered normally, avoiding the safety hazard caused by the lifting door falling. Further, by providing a limiting mechanism on the guide wheel of the transmission mechanism, the transmission wire is transmitted at the correct position of the guide wheel through the limiting mechanism to provide a second guarantee, effectively reducing the possibility of the transmission wire being separated from the guide wheel during the transmission process, helping to prevent the failure of the lifting door or unstable movement caused by the transmission wire being separated from the guide wheel, ensuring the normal operation of the transmission mechanism, and thus ensuring the smooth lifting and lowering of the lifting door.

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

[0080] 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 the passage opening 11 to charge the battery removed from the vehicle. In order to separate the charging area from the battery swap area without affecting the normal driving of the battery swap equipment, a passage opening and closing device 100 will also be provided at the passage opening 11 of the battery swap station.

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

[0082] In this embodiment, the lifting drive mechanism 400 is specifically an electric push rod, which transmits the displacement and driving force generated by the extension and contraction of the electric push rod to the lifting door 13, so that the lifting door 13 can rise to open the passage 11. The counterweight mechanism 500 is specifically a counterweight block in this embodiment, which transmits its weight to the lifting door 13 to balance the gravity of the lifting door 13, so that the electric push rod only needs a small load to drive the lifting door 13. As can be seen from the figure, the lifting drive mechanism 400 and the counterweight mechanism 500 are both located above the lifting door 13, and both are connected and transmitted to the lifting door through their respective transmission mechanisms 200.

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

[0084] Here, the transmission mechanism 200 used to realize the transmission between the lifting drive mechanism 400 and the lifting door 13 is taken as an example. The transmission mechanism 200 includes a plurality of transmission wires 23 and a guide wheel 21. One end of the plurality of transmission wires 23 is respectively connected to the lifting door 13, and the other end of the plurality of transmission wires 23 is respectively connected to the lifting drive mechanism 400 of the passage opening and closing device 100 after passing through the transmission surface of the guide wheel 21. In addition, roller grooves 211 corresponding to the number of transmission wires 23 are provided on the surface of the guide wheel 21, and each roller groove 211 is arranged in parallel to accommodate the corresponding transmission wires 23.

[0085] Meanwhile, the limiting mechanism 300 is disposed on the guide wheel 21 to limit the transmission wire 23 from being separated from the roller groove 211 .

[0086] In this embodiment, the transmission mechanism 200 is provided with a plurality of transmission wires 23 to realize connection with the lifting door 13, so that even if one of the transmission wires 23 falls off from the guide wheel 21 due to external factors, the remaining transmission wires 23 can still maintain a normal working state, so that the lifting door 13 can be lifted and lowered normally, avoiding safety hazards caused by the lifting door 13 falling.

[0087] Furthermore, by providing a limiting mechanism 300 on the guide wheel 21 of the transmission mechanism 200, the transmission wire 23 is transmitted at the correct position of the guide wheel 21 through the limiting mechanism 300, so as to provide a second level of protection, effectively reducing the possibility of the transmission wire 23 detaching from the guide wheel 21 during the transmission process, and helping to prevent problems such as failure or unstable movement of the lifting door 13 caused by the transmission wire 23 detaching from the guide wheel 21, thereby ensuring the normal operation of the transmission mechanism 200, thereby achieving smooth rising and falling of the lifting door 13 under the drive of the lifting drive mechanism 400.

[0088] It should be clearly stated that, in this embodiment, Figure 1 As shown, when the lifting door 13 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 13 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.

[0089] like Figure 3-Figure 4 As shown, further, the guide wheel 21 is connected to the installation door frame 12 through the installation frame 22, and the guide wheel 21 is rotatably arranged on the installation frame 22 to transmit the transmission wire 23.

[0090] The limiting mechanism 300 includes a first limiting member 31 and a second limiting member 32, so as to limit different guide wheels by different limiting methods. Figure 3 As shown, at the edge position of the door frame 12, the limiting mechanism 300 includes a first limiting member 31 arranged on the mounting frame 22, and the connection point between the first limiting member 31 and the mounting frame 22 is located on the side where the guide wheel 21 contacts the transmission wire 23, and the first limiting member 31 extends on the surface of the mounting frame 22 along the axial direction of the guide wheel 21 and covers the outer side of the roller groove 211.

[0091] At the same time, if 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 limiting members 31 and the second limiting members 32 , their extension lengths along the axial direction of the guide wheel 21 should be greater than or equal to the diameter of the transmission wire 23 .

[0096] In this embodiment, the first limiter 31 and the second limiter 32 are both sheet structures formed by bending sheet metal, and are used to accommodate the accommodating grooves of these limiters on the mounting frame 22. Therefore, the first limiter 31 and the second limiter 32 can be positioned and installed in the accommodating grooves in a snap-fitting manner to achieve quick connection and reliable fixation. In addition, the first limiter 31 and the second limiter 32 can be bonded to the mounting frame 22 by a bonding method such as nail-free glue to enhance the stability of the first limiter 31 set on the guide wheel 21.

[0097] In other embodiments, the limit member structure for limiting the position of the transmission wire can also be implemented by an anti-slip cover. Specifically, the anti-slip cover is set on the mounting frame 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 structure of the first limit member 31 and the second limit member 32 provided in this embodiment, the anti-slip cover is larger in size and heavier in weight, and is difficult to disassemble and assemble relative to the guide wheel, which is not conducive to maintenance.

[0098] It should be noted that, although the first limiter 31 and the second limiter 32 provided in this embodiment have a simple structure and are convenient for dark rotation, they have certain limitations in terms of reliable anti-dropping due to the small contact area with the transmission wire 23. However, combined with the scheme of simultaneously leading out two transmission wires 23 for transmission in this embodiment, even if one of the transmission wires 23 falls off under unexpected circumstances, the other transmission wire 23 can still continue to complete the work. Therefore, the scheme of this embodiment selects the first limiter 31 and the second limiter 32 to limit the guide wheel 21. This is a scheme obtained after comprehensive consideration of operational reliability and installation and maintenance difficulty. By combining the structure of the first limiter 31 and the second limiter 32 with the scheme of using multiple transmission wires 23 for synchronous transmission, the installation and maintenance difficulty can be reduced as much as possible while meeting operational reliability.

[0099] In this embodiment, in order to further simplify the installation, the first limit member 31 and the second limit member 32 are designed as a plug-in type, and no screws or nuts are required for auxiliary locking. They only need to be connected by snapping with the mounting frame 22. This not only simplifies the installation process of the first limit member 31 and the second limit member 32 and 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 setting 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 the present embodiment, the stroke amplification component 24 uses a movable pulley group to achieve the function of stroke amplification, and has a simple structure and high reliability. At the same time, by also setting a limit mechanism 300 on the movable pulley group, the transmission wire 23 is prevented from loosening from the surface of the movable pulley group. Of course, in other embodiments, other structural setting schemes that can amplify the stroke can also be used to achieve this, such as a lever structure, etc. Compared with these structural schemes that can amplify the stroke, the first stroke amplification part 241 of the stroke amplification component 24 in the present embodiment adopts a movable pulley group to amplify the stroke. Although the amplification ratio is fixed at 1:2, it has a simple structure and high reliability, which fully meets the operational reliability requirements of the lifting door 13 of this scheme during high-frequency lifting. In addition, the second stroke amplification part 242 of the stroke amplification component 24 in the present embodiment also adopts the structure of a movable pulley group to achieve the transmission connection and stroke amplification between the counterweight mechanism 500 and the lifting door 13. The specific structural layout can be referred to. Figure 1 , and the structure is substantially the same as that of the first stroke amplifying portion 241, so it will not be described herein in detail.

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

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

[0108] Preferably, along the height direction of the passage opening 11 , a horizontally extending limit portion 122 is provided at the lower end of the track 121 , and the limit portion 122 is used to contact with the lower surface of the counterweight mechanism 500 to limit the movement stroke of the counterweight mechanism 500 .

[0109] In this embodiment, the setting of the limit portion 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 when the lifting door 13 moves, and interfering with the normal passage of the battery exchange equipment in the passage opening 11, thereby helping to avoid potential damage or safety risks.

[0110] In addition, if Figure 2As shown, the lifting door 13 and the counterweight mechanism 500 are staggered along the thickness direction of the installation door frame 12. Specifically, when the counterweight mechanism 500 drives the lifting door 13 to move to the desired position, that is, when they 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 will not affect the normal opening and closing function of the lifting door 13 of the passage opening 11. In addition, by staggering the lifting door 13 and the counterweight mechanism 500 along the thickness direction of the installation door frame 12, the space in the installation door frame 12 can be fully utilized to achieve a compact structure arrangement, so that the space occupied by the entire passage opening and closing device 100 can be further reduced.

[0111] like Figure 1 and Figure 3 As shown, the transmission mechanism 200 also includes a reversing assembly 25, the first stroke amplifier 241 includes a first movable pulley 2411, the reversing assembly 25 includes a first steering wheel 251, the moving 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, and the transmission wire 23 led out by the first movable pulley 2411 passes through the first steering wheel 251 and then connected to the top of the lifting door 13.

[0112] In this embodiment, by setting the first movable pulley 2411 on the moving end of the lifting drive mechanism 400 in the first stroke amplifier 241, the transmission wire 23 can be transmitted along the moving direction of the moving 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 drawn out from the first movable pulley 2411, and the reversing 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 mounting 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 drawn out from the first movable pulley 2411, one transmission wire 23 passes through the first steering wheel 251 and 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 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 connected to the left and right ends of the lifting door 13, which helps to balance the movement of the lifting door 13, ensure that the lifting door 13 remains stable during the lifting process, and reduce vibration and swing caused by imbalance. In addition, the reasonable arrangement of the first steering wheel 251 and the second steering wheel 252 helps to guide the transmission wire 23 to transmit in the desired direction, ensuring that the transmission wire 23 does not deviate from the direction during the power transmission process.

[0115] In addition, a directional wheel 253 is provided on the door frame 12 and between the first steering wheel 251 and the second steering wheel 252. After passing through the first steering wheel 251 and before passing through the second steering wheel 252, the transmission wire 23 will pass through the directional wheel 253 and be located at the bottom end of the directional wheel 253 on the side facing the lifting door 13.

[0116] Therefore, in this embodiment, the second limit member 32 is arranged on the mounting frame 22 of the directional wheel 253, and the second limit member 32 is a bending structure, the bending structure is a section extending along the height direction of the passage opening 11 toward one side of the lifting door 13 and extending to the bottom end of the directional wheel 253 facing the lifting door 13, and the other section is extended along the axial direction of the directional wheel 253 and its extended length is not less than the diameter of the transmission wire 23 and a gap is formed between the transmission wire 23.

[0117] In this embodiment, the setting of the directional wheel 253 helps to guide the transmission wire to move along the correct trajectory, and can ensure that the transmission wire passes along the predetermined path, thereby ensuring the normal operation of the lifting door 13. In addition, the second stopper 32 is set at the directional wheel 253 and is set as a bent structure so that it can effectively surround the transmission wire 23 transmitted at the bottom end of the directional wheel 253, avoiding the possibility of the transmission wire 23 detaching from the directional wheel 253 and falling off, ensuring that the transmission wire 23 moves along the correct trajectory, and enhancing the stability of the transmission of the transmission wire 23 at the bottom end of the directional wheel 253.

[0118] In addition, along the height direction of the passage opening 11, when the second stopper 32 is extended toward one side of the lifting door 13, its extended length is greater than the height of the lifting drive mechanism 400. 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] like Figure 1 and Figure 5As shown, the passage opening and closing device 100 also includes a transmission wire adjustment mechanism 600, which is arranged on both sides of the top of the lifting door 13. For any side, there are two transmission wires 23 connected to the lifting door 13 through the transmission wire adjustment mechanism 600. The transmission wire adjustment mechanism 600 is used to adjust the length of each connected transmission wire 23, so that when the lifting door 13 is connected by using multiple transmission wires 23, by adjusting the length of the transmission wire 23, it is avoided that the different lengths of the transmission wires 23 affect the transmission efficiency, thereby meeting the smooth lifting and lowering requirements of the lifting door 13.

[0120] In this embodiment, the transmission wire adjustment mechanism 600 is disposed on both the left and right sides of the lifting door 13. In other embodiments, the location and number of the transmission wire adjustment mechanism 600 can be adjusted as required. Figure 5 As shown, this embodiment further provides a preferred structural setting scheme of a transmission wire adjustment mechanism 600 to facilitate adjustment of the connection length between each transmission wire 23 and the lifting door 13. The transmission wire adjustment mechanism 600 includes two clamping parts 61, a locking part 62 and a base 63.

[0121] The two clamping members 61 are arranged opposite to each other and are respectively connected to the lifting door 13, and the two transmission wires 23 are arranged side by side 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 be relatively close to each other so as to fix the transmission wire 23 between the two clamping members 61.

[0122] Preferably, Figure 5 The clamping member 61 on the right side 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 wire 23, it is only necessary to loosen the clamping member 61 on the left side for adjustment, thereby improving the convenience of operation.

[0123] Therefore, in this embodiment, by providing a locking member 62 to clamp the clamping member 61, the force of the two clamping members 61 being relatively close to each other is used to achieve the connection of multiple transmission wires 23. By unlocking the locking member 62, the clamping force of the two clamping members 61 on the transmission wire 23 can be released, so that the position of the transmission wire 23 relative to the clamping member 61 can be adjusted, thereby achieving the purpose of adjusting the length of the transmission wire 23.

[0124] like Figure 5As shown, the edge of the surface where the clamping member 61 contacts the transmission wire 23 is provided with an arc flange to prevent the corner structure at the edge of the clamping member 61 from pressing the transmission wire 23 during the clamping process and causing damage to the transmission wire 23. At the same time, the provision of the arc flange also reduces the friction 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] Furthermore, there are three locking members 62, 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 adjustment 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 is kept fixed in position with the clamping member 61 due to the action of the remaining unlocked locking member 62. Therefore, through this technical solution, when the transmission wire 23 on one side needs to be adjusted in length, the unlocked locking member 62 can keep the transmission wire 23 on the other side fixed, realizing unilateral adjustment, which is conducive to improving the stability of the multiple transmission wires 23 when driving the lifting door 13 to move.

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

[0127] 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 11 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 also realize the purpose of reliably opening and closing the channel opening 11.

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.
