[0002] Charging and swapping stations for replacing or charging batteries in electric vehicles are widely used. In current charging and swapping stations, battery packs are replaced mainly by moving the battery swapping equipment back and forth between the electric vehicle and the battery compartment. However, due to the presence of the battery swapping equipment, an inlet and outlet are required between the battery compartment and the outside world, which also causes the battery compartment to be connected to the outside world. External debris, animals, and insects may enter through the inlet and outlet, causing damage to the inside of the battery compartment. At the same time, the temperature control in the battery compartment is not easy to maintain.

[0003] In existing battery swap stations, the opening and closing devices at the entrances and exits of battery swap equipment generally have poor sealing properties and cannot effectively prevent the air flow between the battery compartment and the outside world, resulting in poor thermal insulation performance. When in use, even when the lift door is closed, some small foreign objects will still enter the battery compartment, causing damage to the inside of the battery compartment. In addition, when put into use in some cold regions, the poor thermal insulation performance makes it difficult to maintain temperature control in the battery compartment, and the battery cannot reach a suitable working temperature, affecting battery performance and charging efficiency.

[0065] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0066] The present embodiment provides a battery swap station, which includes at least one battery compartment and an operating compartment. The battery compartment is used to store and charge batteries, and the operating compartment is used for electric vehicles to drive in and replace batteries. The battery swap station moves between the battery compartment and the operating compartment through the battery swap equipment and completes the transportation, installation, disassembly, and placement of batteries. Due to the battery working environment requirements and safety requirements, the battery swap compartment needs to be equipped with a lifting door device to form an openable and closable passageway. The lifting door device can close the passageway and open the passageway when personnel or battery swap equipment enter and exit the battery swap station.

[0067] like Figure 1As shown, the present embodiment provides a lifting door device, which is arranged on both sides of the driving passage of the working compartment of the battery swap station, and is used to open and close the moving passage 1 of the battery swap equipment, which 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 swap station. Specifically. The lifting door device of the present embodiment is a lifting lifting door, and the door frame 10 is arranged on one side of the battery compartment. The door frame 10 is provided with 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 movement direction of the door body 20. The transmission mechanism 40 is specifically a gear pair 42 and a synchronous belt 41 provided on the door frame 10. The door body 20 is fixed on the synchronous belt 41. The driving mechanism 50 drives the gear pair 42 to rotate and drives the synchronous belt 41 to roll, thereby lifting or lowering the door body 20. The seal 70 is provided on the end face of the lower part of the door body 20 facing the bottom surface of the battery swap station, and is spread to fill the entire end face. The use of the seal 70 to fill the gap between the door body 20 and the bottom surface of the battery swap station when the door body 20 is closed can improve the sealing and thermal insulation of the battery swap station, and ensure that the interior of the battery swap station can be maintained at a suitable temperature that is more suitable for battery operation when the temperature is low in the cold zone. The seal 70 can be made of commonly used sealing materials such as phases and sponges. As long as it can fill the gap and have a heat preservation effect, it will be fine.

[0068] like Figure 1 , Figure 4 and Figure 6 As shown, a track (not shown in the figure) for the battery swapping equipment to move back and forth is provided in the mobile channel 1. The track is arranged on the bottom surface of the battery swapping station. The seal 70 has an intermittent groove 71. 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 the track can pass through the intermittent groove 71 when the door body 20 is closed. There will be no gap between the door body 20 and the bottom surface of the battery swapping station due to the setting of the track, which further improves the insulation effect. Specifically, the intermittent groove 71 can be equivalent to the width of the track, or it can be slightly narrower than the track, so that the track can be clamped therein by elasticity and the sealing can be improved.

[0069] The thickness of the seal 70 is greater than the height of the track relative to the base plate of the battery swap station. This ensures that when the door 20 is closed, the seal 70 can be completely sealed without causing the door 20 to be lifted up by the track and leaving a gap between the seal 70 and the base plate of the battery swap station because the thickness is smaller than the height of the track relative to the base plate of the battery swap station.

[0070] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the lifting door device also 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 motor. The closing position sensor 60 is fixed to the closing position on the door frame 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, Figure 1 As shown, the door frame 10 includes two longitudinal beams 11 arranged opposite to each other and a cross beam 12 connected between the top ends of the two longitudinal beams 11. The door body 20 is arranged between the two longitudinal beams 11. The position sensors 60 are arranged on the longitudinal beams 11, which can sense whether the door body 20 has reached the corresponding position and send a signal to start or stop the driving mechanism 50 after detecting that the door body 20 has reached the corresponding position. Among them, a closing position sensor 60 is arranged at the bottom position of the door frame 10, and the 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 downward to the position.

[0071] like Figure 1 , Figure 5 As shown, the position sensor 60 also includes an opening position sensor 60, which is fixed on the longitudinal beam 11 of the door frame 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. The opening position sensor 60 and the closing position sensor 60 are set to detect respectively to control the opening and closing of the door.

[0072] like Figure 1 , Figure 2 As shown, it also includes a transmission mechanism 40, and a 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 meshed with the gear pair 42. The 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 swap station. Specifically, the transmission mechanism 40 is not arranged between the door body 20 and the longitudinal beam 11, but is arranged on the mounting surface 111 adjacent to the side of the longitudinal beam 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 beam 11, and the synchronous belt 41 is arranged along the extension direction of the longitudinal beam 11 and bypasses the driving wheel 421 and the driven wheel 422. The door body 20 is fixed to 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 setting positions of the driving wheel 421 and the driven wheel 422. The driving wheel 421 and the driven wheel 422 jointly define the lifting and lowering travel of the door body 20. 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 seat 423. An outwardly protruding mounting seat 423 is arranged on the mounting surface 111 at the bottom end of the longitudinal beam 11, and a rotating shaft is arranged on the mounting seat 423, and the driven wheel 422 is arranged on the rotating shaft. The installation position of the mounting seat 423 is lower than the bottom surface of the battery swap station, which ensures that the lowest point of the lifting and lowering movement of the door body 20 can be equal to or lower than the bottom surface of the battery swap station, ensuring that the door body 20 can contact the bottom surface of the battery swap station. The transmission mechanism 40 is designed to be sunken, and the lowest point is lower than the bottom plate of the battery swap station, which can ensure that the lowest position of the door body 20 can be sealed with the bottom plate of the battery swap station.

[0073] like Figures 1 to 3 As shown, the guide mechanism 30 includes a slide rail 31 arranged on the door frame 10 and a slider 32 arranged on the door body 20 and matched with the slide rail 31. The slider 32 can slide along the slide rail 31 and drive the door body 20 to rise and fall. Specifically, in this embodiment, the slide rail 31 is concave and has a slide groove. The slider 32 is clamped in the slide groove of the slide rail 31 and is limited to only move along the extension direction of the slide rail 31, so that it cannot escape from the slide rail 31 in the horizontal direction. The slider 32 is also fixed to the door body 20 and the synchronous belt 41 at the same time. So that the transmission mechanism 40 and the guide mechanism 30 are both acted on the door body 20 through the slider 32. In this embodiment, the slider 32 is connected to the door body 20 through the connecting plate 21. The slide rail 31 and the slider 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 just aligned with the moving path of the slider 32 so that it detects the position of the slider 32 on the moving path when it moves on the slide rail 31. The slide rail 31 cooperates with the slider 32 to control the lifting and guiding limit of the movement of the door body 20. The lifting and lowering of the door body 20 is controlled by detecting the position of the slider 32 through the position sensor 60, which has a simple structure, low cost and high reliability.

[0074] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a sensor mounting bracket 63 is provided on the door frame 10, and 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. The open position sensor 60 and the closed position sensor 60 are both mounted on the position exactly aligned with the moving path of the slider 32 through the sensor mounting bracket 63. The sensor mounting bracket 63 is an adjustable structure, so that through on-site debugging, it can meet the situation that the door panel is closed down without overpressure. 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 is detachably connected to the door frame 10, and can adjust the longitudinal position of the position sensor 60 and the distance from the slider 32. The mounting portion 632 is used to install the position sensor 60, and is fixedly connected to the fixing portion 631. The mounting portion 632 is provided with a waist hole 633 extending along the extension direction of the slide rail 31. The position sensor 60 is installed in the waist hole 633 and can be fixed at any position of the waist hole 633 along the extension direction thereof. The waist hole 633 structure can conveniently realize longitudinal position adjustment, and is convenient for manual adjustment of the sensor position. In this embodiment, the position sensor 60 is only provided at one end of the longitudinal beam 11, and the sensor mounting bracket 63 is configured so that the position sensor 60 is aligned with the position 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 fixing of the fixing portion 631 to the door frame, while the mounting portion 632 can more easily arrange the position sensor at a position facing the slider. In other embodiments, the position sensor can be fixed by other structures instead of the integral forming method.

[0075] The position sensor 60 may be a common sensor such as an image sensor, a motion sensor, etc., and realizes position detection by detecting the slider 32 .

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