Description

Technical Field

[0001] The present invention relates to the field of battery swapping, and particularly to a lifting door device and a battery swapping station. Background Art

[0002] Charging and battery swapping stations for replacing batteries or charging batteries of electric vehicles are widely used. In current charging and battery swapping stations, the replacement of battery packs is mainly achieved by the back-and-forth movement of battery swapping equipment between electric vehicles and battery compartments. However, due to the existence of battery swapping equipment, there needs to be an access passage opening between the battery compartment and the outside world. As a result, the battery compartment is connected to the outside, and external sundries, animals, and insects may enter through the access passage opening, causing damage to the interior of the battery compartment. At the same time, it is not easy to maintain the temperature control inside the battery compartment.

[0003] In existing battery swapping stations, the opening and closing devices of the access passage opening of the battery swapping equipment generally have poor sealing performance and cannot effectively prevent the air flow between the battery compartment and the outside world, resulting in poor heat preservation performance. When in use, even when the lifting door is in the closed state, some small foreign objects may still enter the battery compartment, causing damage to the interior of the battery compartment. In addition, when put into use in some cold regions, the poor heat preservation performance makes it not easy to maintain the temperature control inside the battery compartment, and it is impossible to reach the appropriate working temperature of the battery, affecting the battery performance and charging efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the opening and closing devices of the access passage opening of the battery swapping equipment have poor sealing and heat preservation performance, there are some small foreign objects entering the battery compartment, resulting in damage to the interior of the battery compartment, and in cold regions, it is impossible to reach the appropriate working temperature of the battery, affecting the battery performance and charging efficiency, and to provide a lifting door device and a battery swapping station.

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

[0006] A lifting door device is provided on both sides of the driving passage of the battery swapping station for opening and closing the moving passage of the battery swapping equipment. It includes a door frame, a door body, and a sealing member is provided at the bottom of the door body. The door body is movably arranged within the door frame and can be switched between an open position and a closed position to open or close the moving passage. When the door body is in the closed position, the sealing member seals between the door body and the bottom plate of the battery swapping station.

[0007] In this solution, adopting the above structure, using the sealing member to fill the gap between the door body and the bottom surface of the battery swapping station when the door body is closed can improve the sealing and heat preservation performance of the battery swapping station, ensuring that when the temperature is relatively low in cold regions, the interior of the battery swapping station can maintain a suitable temperature for the battery to work.

[0008] Preferably, a track for the battery swapping device to move back and forth is provided in the moving channel. The seal has intermittent grooves, and the positions of the intermittent grooves coincide with the projected positions of the track in the vertical direction of the door body.

[0009] In this solution, with the above structure, the intermittent grooves are used to avoid the track, so that when the door body is closed, the track can pass through the intermittent grooves, and there will be no gap between the door body and the bottom surface of the battery swapping station due to the setting of the track, further improving the heat preservation effect.

[0010] Preferably, the thickness of the seal is greater than the height of the track relative to the bottom plate of the battery swapping station.

[0011] In this solution, with the above structure, it is ensured that when the door body is closed, the seal can be completely sealed and there will be no gap between the seal and the bottom plate of the battery swapping station caused by the thickness of the seal being smaller than the height of the track relative to the bottom plate of the battery swapping station, which causes the door body to be lifted by the track.

[0012] Preferably, the lifting door device further includes a driving mechanism and a position sensor. The position sensor includes a closing position sensor. The driving mechanism drives the door body to move up and down. The closing position sensor is fixed at the closing position on the door frame, and the closing position sensor can detect whether the door body reaches the closing position and control the start and stop of the driving mechanism.

[0013] In this solution, with the above structure, a closing position sensor is arranged at the bottom of the door frame and electrically connected to the driving mechanism to control the driving mechanism to stop in time after the door body moves down in place.

[0014] Preferably, it further includes a transmission mechanism. The driving mechanism is used to drive the transmission mechanism to drive the door body to move up and down. The transmission mechanism includes gear pairs arranged at both ends of the moving stroke of the door body and a synchronous belt meshing with the gear pairs. One end of the gear pair located at the lowest position in the moving stroke of the door body is lower than the bottom plate of the battery swapping station.

[0015] In this solution, with the above structure, the transmission mechanism has a sunken design, and the lowest point is lower than the bottom plate of the battery swapping station, which can ensure the seal between the lowest position of the door body and the bottom plate of the battery swapping station.

[0016] Preferably, it further includes a guiding mechanism. The guiding mechanism includes a sliding rail arranged on the door frame and a sliding block arranged on the door body and cooperating with the sliding rail. The sliding block can slide along the sliding rail and drive the door body to rise and fall;

[0017] The position sensor detects the position of the sliding block on the moving path when the sliding block moves on the sliding rail.

[0018] In this solution, with the above structure, the slide rail cooperates with the slider to control the lifting and guide and limit the movement of the door body. The position sensor is used to detect the position of the slider to control the lifting of the door body, with a simple structure, low cost, and high reliability.

[0019] Preferably, the position sensor further includes an opening position sensor, which is fixed on the door frame and detects the position on the moving path of the slider when it moves on the slide rail. The opening position sensor can detect whether the door body reaches the opening position and control the start and stop of the driving mechanism.

[0020] In this solution, with the above structure, by setting an opening position sensor and a closing position sensor respectively for detection to control the opening and closing of the door.

[0021] Preferably, a sensor mounting bracket is provided on the door frame. The sensor mounting bracket is detachably connected to the door frame, and the position sensor is adjustably mounted on the sensor bracket.

[0022] In this solution, with the above structure, the sensor mounting bracket is an adjustable structure to meet the condition that the door panel is tightly closed downward without overpressure through on-site debugging.

[0023] Preferably, the sensor mounting bracket includes a fixing part and a mounting part. The fixing part is connected to the door frame, the mounting part is connected to the fixing part, and a long hole extending along the extending direction of the slide rail is formed on the mounting part. The position sensor is mounted in the long hole and can be fixed at any position along its extending direction.

[0024] In this solution, with the above structure, the longitudinal position adjustment can be conveniently realized through the long hole structure, which is convenient for manually adjusting the position of the sensor.

[0025] Preferably, a buffer is provided on one side of the top of the door frame facing the door body.

[0026] In this solution, with the above structure, the buffer prevents the door body and the door frame from colliding and wearing when the door is opened. Setting the buffer on the door frame can reduce the weight of the door body compared with setting it on the door body.

[0027] A swapping station includes the lifting door device as described above.

[0028] In this solution, with the above structure, the lifting door device of the swapping station uses a seal to fill the gap between the door body and the bottom surface of the swapping station when the door is closed, which can improve the sealing and heat preservation of the swapping station and ensure that the interior of the swapping station can maintain a more suitable temperature for battery operation when the temperature is low in cold regions.

[0065] The following is a preferred embodiment, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0066] This embodiment provides a battery swapping station, which includes at least one battery compartment and an operation compartment. The battery compartment is used to store batteries and charge the batteries, and the operation compartment is used for electric vehicles to drive in and replace the batteries. The battery swapping station moves between the battery compartment and the operation compartment through battery swapping equipment and completes work such as transportation, installation, disassembly, and placement of batteries. Due to the requirements of the battery working environment and safety, the battery swapping compartment needs to be provided with a lifting door device to form an openable and closable passage opening. The lifting door device can close the passage opening and open the passage opening when personnel or battery swapping equipment enter or leave the battery swapping station.

[0067] As Figure 1As shown in the figure, this embodiment provides a lifting door device, which is arranged on both sides of the driving passage of the operation bin of the battery swapping station and is used to open and close the moving passage 1 of the battery swapping equipment. It includes a door frame 10, a door body 20, and a sealing member 70 is arranged at the bottom of the door body 20. The door body 20 is movably arranged in the door frame 10 and can be switched between an open position and a closed position to open or close the moving passage 1. When the door body 20 is in the closed position, the sealing member 70 is sealed between the door body 20 and the bottom plate of the battery swapping station. Specifically. The lifting door device of this embodiment is a lifting type lifting door. The door frame 10 is arranged on one side of the battery bin. A transmission mechanism 40 for driving the door body 20 to move up and down, a driving mechanism 50 for driving the transmission mechanism 40 to move, and a guiding mechanism 30 for guiding and limiting the moving direction of the door body 20 are arranged on the door frame 10. The transmission mechanism 40 is specifically a gear pair 42 and a synchronous belt 41 arranged on the door frame 10. The door body 20 is fixed to the synchronous belt 41. The driving mechanism 50 drives the gear pair 42 to rotate to drive the synchronous belt 41 to roll, thereby lifting or lowering the door body 20. The sealing member 70 is arranged on the end face of the lower part of the door body 20 facing the bottom surface of the battery swapping station and covers the entire end face. Using the sealing member 70 to fill the gap between the door body 20 and the bottom surface of the battery swapping station when the door body 20 is closed can improve the sealing performance and heat preservation performance of the battery swapping station, ensuring that when the temperature is low in cold regions, the interior of the battery swapping station can maintain a suitable temperature more suitable for the battery to work. The sealing member 70 can be selected from common sealing materials such as sponge, etc. As long as it can play the role of filling gaps and heat preservation.

[0068] As Figure 1 , Figure 4 and Figure 6 shown, a track (not shown in the figure) for the battery swapping equipment to move back and forth is arranged in the moving passage 1. The track is arranged on the bottom surface of the battery swapping station. The sealing member 70 has an intermittent groove 71, and the position of the intermittent groove 71 is consistent with the projection position of the track in the vertical direction of the door body 20. The intermittent groove 71 is used to avoid the track, so that when the door body 20 is closed, the track can pass through the intermittent groove 71, and there will be no gap between the door body 20 and the bottom surface of the battery swapping station due to the arrangement of the track, further improving the heat preservation effect. Specifically, the intermittent groove 71 can be equivalent to the width of the track or slightly narrower than the track, so as to elastically clamp the track therein and improve the sealing performance.

[0069] The thickness of the sealing member 70 is greater than the height of the track relative to the bottom plate of the battery swapping station. Ensure that when the door body 20 is closed, the sealing member 70 can be completely sealed and there will be no gap between the sealing member 70 and the bottom plate of the battery swapping station because the thickness is smaller than the height of the track relative to the bottom plate of the battery swapping station, which causes the door body 20 to be lifted by the track.

[0070] As Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the lifting door device further includes a driving mechanism 50 and a position sensor 60. The position sensor 60 includes a closing position sensor 60. The driving mechanism 50 drives the door body 20 to move up and down to switch between the open position and the closed position. The driving mechanism 50 is a kind of motor. The closing position sensor 60 is fixed at the closing position on the doorframe 10. The closing position sensor 60 can detect whether the door body 20 reaches the closing position and control the start and stop of the motor. Specifically, in this embodiment, as Figure 1 shown, the doorframe 10 includes two longitudinals 11 arranged oppositely and a crossbeam 12 connected between the tops of the two longitudinals 11. The door body 20 is arranged between the two longitudinals 11. The position sensors 60 are all arranged on the longitudinals 11, and can sense whether the door body 20 reaches the corresponding position and send a signal to start or stop the driving mechanism 50 after detecting that the door body 20 reaches the corresponding position. Among them, a closing position sensor 60 is arranged at the bottom position of the doorframe 10, and this position corresponds to the closing position of the door body 20. The closing position sensor 60 is electrically connected to the motor to control the door body 20 to stop in time after moving down in place.

[0071] As Figure 1 、 Figure 5 shown, the position sensor 60 further includes an opening position sensor 60. The opening position sensor 60 is fixed on the longitudinal 11 of the doorframe 10. The opening position sensor 60 can detect whether the door body 20 reaches the opening position and control the start and stop of the motor. By setting the opening position sensor 60 and the closing position sensor 60 respectively for detection to control opening and closing the door.

[0072] As Figure 1 、 Figure 2 shown, it further includes a transmission mechanism 40. The driving mechanism 50 is used to drive the transmission mechanism 40 to drive the door body 20 to move up and down. The transmission mechanism 40 includes a gear pair 42 arranged at both ends of the moving stroke of the door body 20 and a synchronous belt 41 meshing with the gear pair 42. One end of the gear pair 42 located at the lowest position in the moving stroke of the door body 20 is lower than the bottom plate of the battery swapping station. Specifically, the transmission mechanism 40 is not arranged between the door body 20 and the longitudinal 11, but is arranged on the installation surface 111 adjacent to the side of the longitudinal 11 facing the door body 20. The gear pair 42 includes a driving wheel 421 and a driven wheel 422 arranged at the upper and lower positions of the longitudinal 11. The synchronous belt 41 is arranged along the extending direction of the longitudinal 11 and bypasses the driving wheel 421 and the driven wheel 422. The door body 20 is fixed at a specific position of the transmission belt. When the driving wheel 421 is driven by the driving mechanism 50 to rotate, the driving wheel 421 drives the synchronous belt 41 to rotate, and then drives the driven wheel 422 to rotate. When the synchronous belt 41 rotates, the specific position fixed to the door body 20 can move between the set positions of the driving wheel 421 and the driven wheel 422. The moving stroke of the door body 20 for lifting and lowering is jointly defined by the driving wheel 421 and the driven wheel 422. As Figure 1 、Figure 6 As shown, the driven wheel 422 in the gear pair 42 is arranged at the bottom end of the longitudinal beam 11 through the mounting base 423. An outwardly protruding mounting base 423 is arranged on the mounting surface 111 at the bottom end of the longitudinal beam 11. A rotating shaft is arranged on the mounting base 423, and the driven wheel 422 is arranged on the rotating shaft. The mounting position of the mounting base 423 is lower than the bottom surface of the battery swapping station, ensuring that the lowest point of the lifting and moving stroke of the door body 20 can be equal to or lower than the bottom surface of the battery swapping station, and ensuring that the door body 20 can contact the bottom surface of the battery swapping station. The transmission mechanism 40 is designed in a sunken manner, and the lowest point is lower than the bottom plate of the battery swapping station, which can ensure the sealing between the lowest position of the door body 20 and the bottom plate of the battery swapping station.

[0073] As Figures 1 to 3 shown, the guiding mechanism 30 includes a sliding rail 31 arranged on the door frame 10 and a sliding block 32 arranged on the door body 20 and cooperating with the sliding rail 31. The sliding block 32 can slide along the sliding rail 31 and drive the door body 20 to rise and fall. Specifically, in this embodiment, the sliding rail 31 is concave with a sliding groove, and the sliding block 32 is clamped in the sliding groove of the sliding rail 31 and is restricted to move only along the extending direction of the sliding rail 31, so that it cannot escape from the sliding rail 31 in the horizontal direction. The sliding block 32 is also fixedly connected to both the door body 20 and the synchronous belt 41 at the same time. So that both the transmission mechanism 40 and the guiding mechanism 30 act on the door body 20 through the sliding block 32. In this embodiment, the sliding block 32 is connected to the door body 20 through the connecting plate 21. The sliding rail 31 and the sliding block 32 are both arranged on the mounting surface 111 of the longitudinal beam 11, and the opening position sensor 60 and the closing position sensor 60 are exactly aligned with the moving path of the sliding block 32 to detect the position of the sliding block 32 on the moving path when it slides on the sliding rail 31. The sliding rail 31 cooperates with the sliding block 32 to control the lifting and guide and limit the movement of the door body 20. And the lifting of the door body 20 is controlled by detecting the position of the sliding block 32 through the position sensor 60. The structure is simple, the cost is low, and the reliability is high.

[0074] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7 shown, a sensor mounting bracket 63 is arranged on the door frame 10. The sensor mounting bracket 63 is detachably connected to the door frame 10, and the position sensor 60 is adjustably mounted on the sensor bracket. Both the opening position sensor 60 and the closing position sensor 60 are mounted on the position exactly aligned with the moving path of the sliding block 32 through the sensor mounting bracket 63. The sensor mounting bracket 63 is an adjustable structure to meet the situation that the door panel is tightly closed downward without overpressure through on-site debugging. Specifically, as Figure 7As shown, the sensor mounting bracket 63 includes a fixing portion 631 and a mounting portion 632. The fixing portion 631 is connected to the door frame 10, and it is detachably connected to the door frame 10, capable of adjusting the longitudinal position of the position sensor 60 and the distance from the slider 32. The mounting portion 632 is used to mount the position sensor 60, and it is fixedly connected to the fixing portion 631. An oblong hole 633 extending along the extending direction of the slide rail 31 is formed in the mounting portion 632. The position sensor 60 is mounted in the oblong hole 633 and can be fixed at any position along its extending direction. The longitudinal position adjustment can be conveniently achieved through the structure of the oblong hole 633, which is convenient for manually adjusting the position of the sensor. In this embodiment, the position sensor 60 is provided only at one end of the longitudinal beam 11, and the sensor mounting bracket 63 is arranged such that the position sensor 60 is exactly aligned with the positions of the slider 32 when the door body 20 is in the open position and the closed position. In this embodiment, the fixing portion 631 and the mounting portion 632 of the sensor mounting bracket 63 are integrally formed L-shaped plates perpendicular to each other. This structure can facilitate the fixation of the fixing portion 631 to the door frame, and at the same time, it is easier for the mounting portion 632 to arrange the position sensor to face the slider. In other embodiments, the integrally formed manner may not be adopted, and other structures may be used to fix the position sensor.

[0075] The position sensor 60 can adopt common sensors such as image sensors and motion sensors, and it realizes position detection by detecting the slider 32.

[0076] As Figure 1 , Figure 5 shown, a buffer member 121 is provided on the side of the top of the door frame 10 facing the door body 20. The buffer member 121 prevents the door body 20 and the door frame 10 from colliding and wearing when opening the door. Setting the buffer member 121 on the door frame 10 can reduce the weight of the door body 20 compared with setting it on the door body 20. In this embodiment, the buffer member 121 can be set as a mechanism with a certain elasticity to absorb the impact force through elasticity. The buffer member 121 can also choose a structure with a certain ductility such as foam plastic to absorb energy.
