Description

[0001] This application is a divisional application of a Chinese patent application with an application date of September 3, 2020, application number 202010917627.9, and invention name “Battery exchange channel door device and battery exchange station including the same”. Technical Field

[0002] The present invention relates to a battery-swapping passage door device and a battery-swapping station comprising the same. Background Art

[0003] At present, battery swapping stations usually use battery swapping equipment to transport batteries. The battery swapping equipment moves along the battery swapping channel between the electric vehicle and the charging warehouse or transfer equipment to transport the battery. During the operation of the battery swapping equipment, if a person is on the battery swapping channel, he will collide with the battery swapping equipment, causing great safety hazards, which will cause great damage not only to the personnel but also to the battery swapping equipment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that the battery swapping equipment is prone to collision with people in the battery swapping channel, causing damage and safety hazards, and to provide a battery swapping channel door device and a battery swapping station including the same.

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

[0006] A battery exchange channel door device is provided at the entrance and exit of a battery exchange device in a battery exchange station, and is used to open or close the entrance and exit. The battery exchange channel door device comprises: a flip door, and the flip door is configured to switch between a closed state and an open state, wherein:

[0007] In the closed state, the flip door seals the entrance and exit;

[0008] In the open state, the flip door rotates relative to the inlet and outlet to above the battery exchange channel.

[0009] In this solution, the vehicle loading platform and the battery swapping compartment are isolated from each other, and the battery swapping equipment can enter and exit the battery swapping compartment along the battery swapping channel by opening the flip door. When the flip door is closed, the battery swapping compartment can be isolated from the outside world to avoid being affected by the outside world.

[0010] Among them, when the battery swapping equipment enters or leaves the vehicle loading platform, the flip door remains open and can form a barrier above the battery swapping channel. As a result, pedestrians cannot enter the battery swapping channel by crossing the flip door blocking the battery swapping channel, so that pedestrians can only stay on both sides of the battery swapping channel and cannot enter or cross the battery swapping channel. When the flip door is closed, personnel can be allowed to pass safely. Therefore, this solution ensures the safety of personnel during battery swapping and avoids damage caused by collisions between battery swapping equipment and personnel during operation. At the same time, when the flip door is closed, it covers the battery swapping equipment and closes the import and export of the battery swapping equipment, which plays a role in safety protection, prevents dust or rainwater from entering the battery swapping compartment where the battery swapping equipment is located, and increases the service life of the equipment in the battery swapping compartment.

[0011] In addition, the space occupied by the rotation of the flip door is the space above the battery exchange channel, which will not affect the operating space of other equipment. At the same time, the installation structure of the flip door is simple, and the installation space occupied by the structure of the lifting door is significantly reduced.

[0012] Preferably, the flip door comprises a door panel, wherein the top of the door panel is rotatably connected to the inlet and outlet, the door panel is used to cover the inlet and outlet, and a flexible member is provided at the bottom of the door panel.

[0013] When the flip door is closed, the flexible part isolates the space between the bottom of the door panel and the battery exchange channel to prevent debris from entering. At the same time, the flexible part also plays a buffering role to prevent the bottom of the door panel from directly colliding with other objects. When people's feet are extended, the flexible part can prevent them from being pressed.

[0014] Preferably, the door panel comprises a base plate and a protruding portion connected to the bottom of the base plate, wherein the protruding portion extends outwardly along a surface of the base plate.

[0015] When the flip door is closed, the interior of the protrusion can fit and accommodate the battery swap equipment, which can effectively protect the battery swap equipment that cannot fully enter the battery swap compartment while ensuring that the battery swap compartment is isolated from the vehicle loading platform. This can reduce the space occupied by the battery swap equipment in the battery swap compartment.

[0016] Preferably, the protrusion includes a top plate, a side plate and an end plate, wherein the top plate and the side plate are vertically connected to the base plate, the end plate is connected to the top plate and the side plate and is parallel to the base plate, and a accommodating cavity is formed between the top plate, the side plate and the end plate.

[0017] The top plate, side plates and end plates form a longitudinal depth along the battery exchange channel, so that the accommodating cavity can accommodate the battery exchange equipment. At the same time, the top plate, side plates and end plates only leave openings at the bottom, and the side plates and end plates form a semi-enclosed structure and are connected to the flexible parts, so that the flexible parts can block foreign objects from entering from the side, front and top.

[0018] Preferably, an arc-shaped transition portion is provided between the top plate and the end plate, and the arc-shaped transition portion can reduce the edges and corners of the flip door, thereby reducing damage when the flip door collides.

[0019] Preferably, there is a certain gap between the bottom of the protrusion and the driving plane of the battery exchange equipment, and the flexible member is arranged at the bottom of the protrusion and covers at least a part of the gap.

[0020] The protrusion is located at the bottom of the flip door. This arrangement allows the flexible component to isolate the space between the bottom of the protrusion and the driving plane of the battery exchange equipment, thereby preventing debris from entering.

[0021] Preferably, the flexible member is one or more of a brush, an elastic sheet, and a curtain.

[0022] Preferably, the protrusion and the base plate are integrally connected or detachably connected.

[0023] The protrusion can be integrally formed with the substrate, has good strength and is easy to manufacture. The detachable protrusion can be easily replaced to meet the needs of different battery replacement equipment.

[0024] Preferably, a sensor is provided on the flip door, and the sensor is used to detect whether there is an object approaching the flip door. The sensor can realize early warning of the power exchange station, remind people who are approaching or about to pass through the power exchange channel, and prevent people who walk with their heads down from ignoring the existence of the flip door.

[0025] The sensor is further installed on the side of the substrate facing the inside of the battery swap compartment through a bracket. As a result, when the flip door is closed, the sensor is retained in the battery swap compartment and does not perform detection. When the flip door is open, the sensor is flipped out along with the flip door, so that objects can be detected. In addition, the side of the flipped substrate facing the battery swap compartment is set downward, and the sensor will not exceed the height of the flip door 1, so it will not take up more space.

[0026] Preferably, the battery exchange channel door device also includes a driving device, wherein the flip door is connected to the driving device and is driven by the driving device to switch between a closed state and an open state.

[0027] Preferably, the inlet and outlet include a door frame, the door frame is fixedly arranged on the battery exchange box of the battery exchange station, and the flip door is rotatably connected to the door frame, wherein one end of the drive device is connected to the fixed frame, and the other end is connected to the flip door. Thus, the door frame, the flip door and the drive device form an integral structure and can be installed as a whole. Among them, the door frame provides stability and provides support for the rotation of the flip door to facilitate repeated driving of the drive device. In addition, by providing support through the door frame, other structures can be reduced, simplifying the overall installation structure of the battery exchange channel door device.

[0028] When the driving device is telescopically moving, the distance between the two ends and the connection between the fixed frame and the flip door is changed. Since the flip door is connected to the door frame by rotation, the movement trajectory of the connection between the driving device and one side of the flip door is an arc, while the connection between the driving device and the fixed frame remains in place. Therefore, the driving device adapts to the change in the distance between the two side connections by rotating the two ends.

[0029] Preferably, the driving device is an electric cylinder, and both sides of the electric cylinder can generate relative telescopic movement, wherein one side of the electric cylinder is rotationally connected to a fixed frame, and the other side of the electric cylinder is rotationally connected to the flip door.

[0030] The electric cylinder generates a large driving force and operates reliably, which can ensure that the battery-swap channel door device can operate stably during repeated opening and closing, reducing failures. At the same time, the electric cylinder occupies a small space in the height direction, which can reduce the installation space in the height direction of the battery-swap channel door device.

[0031] A battery swap station, characterized in that the station comprises a battery swap warehouse, battery swap equipment and a vehicle loading platform, the battery swap equipment moves back and forth between the battery swap warehouse and the vehicle loading platform to replace batteries of electric vehicles located on the vehicle loading platform, and an entrance and exit for the battery swap equipment are provided on the side of the battery swap warehouse facing the vehicle loading platform, wherein the battery swap channel door device is provided on the entrance and exit.

[0032] Preferably, when the flip door is opened, there is a certain gap between the end of the flip door and the electric vehicle to prevent the door of the electric vehicle from opening. When the flip door is opened, the end of the flip door is close to the electric vehicle and there is a certain gap between the end of the flip door and the electric vehicle, and at the same time, it plays a role in preventing the door of the electric vehicle from opening, thereby preventing people inside the electric vehicle from opening the door, avoiding safety hazards caused by people walking out of the vehicle.

[0033] Preferably, a flexible member is provided at the bottom of the flip door, and when the flip door is opened, the flexible member is close to the electric vehicle to prevent damage to the door. When the flip door is opened, the flexible member at the bottom of the flip door is close to the electric vehicle, avoiding a hard collision of the flip door with the vehicle. Even if the flexible member hits the electric vehicle, it will be deformed, thereby reducing the impact on the electric vehicle and avoiding damage.

[0034] The positive and progressive effects of the present invention are: the present invention prevents pedestrians or external impurities from entering the battery exchange channel during the operation of the battery exchange equipment, ensures the safety of personnel during battery exchange, and avoids damage caused by collisions between the battery exchange equipment and personnel during operation. At the same time, after the battery exchange is completed, the flip door is closed to prevent external impurities from entering the battery exchange compartment and contaminating the equipment in the battery exchange compartment, thereby increasing the service life of the battery exchange compartment. At the same time, the installation structure of the flip door is simple and occupies less installation space. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0044] like Figure 1 and Figure 2As shown, the present embodiment provides a battery swap station 8, which is mainly built with containers, and includes a battery swap warehouse 80, a battery swap device 9 and a vehicle loading platform 6. The battery swap device 9 moves back and forth between the battery swap warehouse 80 and the vehicle loading platform 6 to replace the battery of the electric vehicle 7 located on the vehicle loading platform 6. The battery swap warehouse 80 is provided with an entrance and exit 30 for the battery swap device 9 on the side facing the vehicle loading platform 6, wherein a battery swap channel door device is provided on the entrance and exit 30.

[0045] like Figure 1 and Figure 2 As shown, the battery exchange channel door device of this embodiment is arranged at the entrance and exit 30 of the battery exchange equipment 9 in the battery exchange station, and is used to open or close the entrance and exit 30, including a flip door 1. The flip door 1 of this embodiment is set to switch between a closed state and an open state, wherein, as Figure 1 As shown, in the closed state, the flip door 1 closes the access port 30. Figure 2 As shown, in the open state, the flip door 1 rotates relative to the entrance and exit 30 to above the battery exchange channel 5.

[0046] like Figure 1 As shown, the battery replacement channel 5 of this embodiment is Figure 1 and Figure 2 The battery exchange channel 5 extends along the first direction X and extends to the vehicle loading platform 6. The vehicle loading platform 6 is used to carry and position the electric vehicle 7. The electric vehicle 7 enters or exits the vehicle loading platform 6 along the second direction Y, wherein the first direction is perpendicular to the second direction Y, the first direction X is the length direction of the electric vehicle, and the second direction Y is the width direction of the electric vehicle 7. A battery exchange device 9 travel track is provided on the battery exchange channel 5. The track extends along the first direction X and passes through the vehicle loading platform 6. The battery exchange device 9 travels along the battery exchange channel 5 to the bottom of the electric vehicle 7 on the vehicle loading platform 6 to replace the battery.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, the vehicle loading platform 6 and the battery swap compartment 80 are isolated from each other. By opening the flip door 1, the passage between the two can be opened, and the battery swap equipment 9 can enter and exit the battery swap compartment 80 along the battery swap channel 5. When the flip door 1 is closed, it can ensure that the battery swap compartment 80 is isolated from the outside world to avoid being affected by the outside world.

[0048] like Figure 2As shown, when the battery exchange device 9 of this embodiment enters or leaves the vehicle loading platform 6, the flip door 1 remains open and can form a barrier above the battery exchange channel 5, which blocks the space outside the electric vehicle 7. As a result, pedestrians cannot enter the battery exchange channel 5 by crossing the flip door 1 blocking the battery exchange channel 5, so that pedestrians can only stay on both sides of the battery exchange channel 5 and cannot enter or cross the battery exchange channel 5. When the flip door 1 is in a closed state, people can be allowed to pass safely. Therefore, this solution ensures the safety of personnel during battery exchange and avoids damage caused by collisions between the battery exchange equipment 9 and personnel during operation.

[0049] In addition, the space occupied by the rotation of the flip door 1 is the space above the battery exchange channel 5, which will not affect the operating space of other equipment. At the same time, the installation structure of the flip door 1 is simple, and the installation space occupied by the structure of the lifting door is significantly reduced.

[0050] like Figure 3 and Figure 5 As shown, the flip door 1 of this embodiment includes a door panel 10, wherein the top of the door panel 10 is rotatably connected to the inlet and outlet 30, and specifically can be hinged. The door panel 10 is used to block the inlet and outlet 30, thereby isolating the interior of the battery exchange compartment 80. A flexible member 11 is provided at the bottom of the door panel 10. When the flip door 1 is opened, the flexible member 11 is close to the electric vehicle 7 to prevent damage to the door. The flexible member 11 of this embodiment is one or more of a brush, an elastic sheet, and a curtain. When the flip door 1 is closed, the flexible member 11 isolates the space between the bottom of the door panel 10 and the battery exchange channel 5 on the one hand to prevent debris from entering. At the same time, the flexible member 11 also plays a buffering role on the other hand, preventing the bottom of the door panel 10 from directly colliding with other objects. When a person's feet are extended, the flexible member 11 can prevent feet from being pressed.

[0051] like Figure 5 and Figure 6 As shown, compared with the door frame 3, the bottom of the protrusion 12 of this embodiment has a certain gap from the driving plane of the battery exchange device 9, and the flexible member 11 is arranged at the bottom of the protrusion 12 and covers at least a part of the gap. Since the protrusion 12 is located at the bottom of the flip door 1, the flexible member 11 can isolate the space between the bottom of the protrusion 12 and the driving plane of the battery exchange device 9, thereby preventing debris from entering.

[0052] like Figure 4 and Figure 5 As shown, the door panel 10 of this embodiment includes a base plate 101 and a protrusion 12 connected to the bottom of the base plate 101, wherein the protrusion 12 extends outward along the surface of the base plate 101, specifically protruding toward the side where the vehicle loading platform 6 is located.

[0053] like Figure 1and Figure 5 As shown, when the flip door 1 is in the closed state, the interior of the protrusion 12 can adapt to and accommodate the battery swapping equipment 9, while ensuring that the battery swapping compartment is isolated from the vehicle loading platform 6, it can also avoid interference with the battery swapping equipment 9 that has not fully entered the entrance and exit 30. The space occupied by the battery swapping equipment 9 in the battery swapping compartment can be reduced. When the battery swapping equipment 9 is not in use, it is completely or partially located in the battery swapping compartment. When it is partially located in the battery swapping compartment 80, the part that exceeds the edge of the battery swapping compartment 80 can be accommodated by providing a flip door 1 with a protrusion. On the one hand, the battery swapping equipment 9 located outside the battery swapping compartment 80 can be accommodated, making the structure of the battery swapping station more compact and reducing the floor space of the battery swapping station; on the other hand, during the operation of the battery swapping equipment 9, it can prevent people from entering the battery swapping channel 5 to cause battery swapping accidents. After the battery swapping action is completed, the flip door 1 can be closed to prevent external impurities from entering the battery swapping compartment 80 and polluting the battery swapping compartment 80.

[0054] like Figure 6 As shown, the protrusion 12 of this embodiment further includes a top plate 103, a side plate 104 and an end plate 102, wherein the top plate 103 and the side plate 104 are vertically connected to the base plate 101, the end plate 102 is connected to the top plate 103 and the side plate 104 and is parallel to the base plate 101, and a accommodating cavity 13 is formed between the top plate 103, the side plate 104 and the end plate 102.

[0055] like Figure 6 As shown, the top plate 103, the side plate 104 and the end plate 102 of this embodiment form a longitudinal depth along the battery exchange channel 5, so that the accommodating cavity 13 can accommodate the battery exchange device 9. At the same time, the top plate 103, the side plate 104 and the end plate 102 only leave an opening at the bottom, and the side plate 104 and the end plate 102 form a semi-enclosed structure and are connected to the flexible member 11, so that the flexible member 11 can block foreign objects from entering from the side, front and top.

[0056] like Figure 7 As shown, an arc-shaped transition portion 105 is provided between the top plate 103 and the end plate 102 of the present embodiment. The arc-shaped transition portion 105 can reduce the edges and corners of the flip door 1, and can reduce damage when the flip door 1 collides. At the same time, the stress at the arc-shaped transition portion 105 is not concentrated, which can facilitate the production of the protrusion 12 in an integral manner. Furthermore, the protrusion 12 and the substrate 101 can be integrally connected. Of course, it can also be a detachable connection. Among them, the protrusion 12 and the substrate 101 are integrally formed, which has good strength and is easy to manufacture. The detachable protrusion 12 can be easily replaced to adapt to the needs of different battery exchange equipment 9.

[0057] In other embodiments, the protrusion 12 may be other shapes, such as an arc-shaped protrusion or a protrusion 12 formed by splicing together multiple shapes, as long as it can accommodate the portion of the battery swapping device 9 that protrudes beyond the battery swapping compartment 80 and does not affect the battery swapping operation when it is flipped up.

[0058] In addition, the height of the entire flip door 1 of this embodiment is less than or equal to the distance between the battery exchange compartment 80 and the electric vehicle 7 on the vehicle loading platform 6. Therefore, after the flip door 1 is flipped, it will not hit the electric vehicle 7, avoiding interference and damage.

[0059] In this embodiment, when the flip door 1 is opened, there is a certain gap between the end of the flip door 1 and the electric vehicle 7 to prevent the door of the electric vehicle 7 from opening. As a result, people inside the electric vehicle 7 cannot open the door, avoiding safety hazards caused by people walking out of the vehicle. Figure 5 and Figure 6 As shown, the flip door 1 of this embodiment is provided with a sensor 4, which is used to detect whether there is an object approaching the flip door 1. The sensor 4 can realize the early warning of the battery swap station, remind the personnel approaching or passing through the battery swap channel 5, and prevent the personnel who walk with their heads down from ignoring the existence of the flip door 1.

[0060] like Figure 5 and Figure 6 As shown, the sensor 4 of this embodiment is installed on the side of the substrate 101 facing the inside of the battery swap compartment 80 through the bracket 41. Therefore, when the flip door is closed, the sensor 4 is retained in the battery swap compartment 80 and no detection is performed. When the flip door is open, the sensor 4 is flipped out together with the flip door 1, so that objects can be detected. In addition, the side of the flipped substrate 101 facing the battery swap compartment 80 is set downward, and the sensor 4 will not exceed the height of the flip door 1, so it will not take up more space. The sensor 4 can be one or more of an infrared sensor, a distance sensor, a laser sensor, and a visual sensor. The sensor 4 can detect whether there is an object approaching the flip door by emitting a light signal and receiving a return signal, or by image recognition.

[0061] like Figure 3 and Figure 4As shown, the battery exchange channel door device of this embodiment also includes a driving device 2, wherein the flip door 1 of this embodiment is connected to the driving device 2, and is driven by the driving device 2 to switch between a closed state and an open state. The driving device 2 of this embodiment is further configured as an electric cylinder, and the two sides of the electric cylinder can generate relative telescopic movement. Of course, in other embodiments, other types of power elements can also be used, such as motors, hydraulic cylinders, cylinders, etc. The driving force generated by the electric cylinder in this embodiment is large and the operation is reliable, which can ensure that the battery exchange channel door device can operate stably during repeated opening and closing, and reduce failures. At the same time, the electric cylinder occupies a small space in the height direction, which can reduce the installation space of the battery exchange channel door device in the height direction.

[0062] like Figure 3 As shown, the inlet and outlet 30 of this embodiment is located in the door frame 3, and the door frame 3 is fixedly arranged on the battery swap compartment body of the battery swap station. The flip door 1 is rotatably connected to the door frame 3, wherein one end of the driving device 2 of this embodiment is connected to the door frame 3, and the other end is connected to the flip door 1. As a result, the door frame 3, the flip door 1 and the driving device 2 become an integral structure and can be installed as a whole. Among them, the door frame 3 provides stability and provides support to the flip door 1 to facilitate repeated driving of the driving device 2. In addition, by providing support through the door frame 3, other structures can be reduced, simplifying the overall installation structure of the battery swap channel door device.

[0063] like Figure 3 and Figure 8 As shown, one side of the driving device 2 of this embodiment is rotationally connected to the fixed frame 81 in the battery swap station 8, and the other side of the driving device 2 is rotationally connected to the flip door 1. Therefore, when the driving device 2 is telescopic, the distance between the two ends and the connection between the fixed frame 81 and the flip door 1 is changed. Since the flip door 1 is rotationally connected to the door frame 3, the movement trajectory of the connection between the driving device 2 and one side of the flip door 1 is an arc, while the connection between the driving device 2 and the fixed frame 81 remains in place, so that the driving device 2 adapts to the change in the distance between the two side connections by rotating the two ends.

[0064] In summary, the present invention prevents pedestrians from entering the battery exchange passage through the flip door blocking the battery exchange passage during battery exchange, thereby ensuring the safety of personnel during battery exchange and avoiding damage caused by collisions between battery exchange equipment and personnel during operation. At the same time, the installation structure of the flip door is simple and occupies less installation space.
