[0086] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0087] Figure 1-2 According to an embodiment of the present invention, a battery swap station 100 is illustrated. The battery swap station 100 is used to provide an automatic battery replacement service for an electric vehicle 40.

[0088] In this embodiment, the battery swap station 100 includes: two battery swap bays 101 arranged opposite to each other, and a battery swap parking area 105 is formed between the two battery swap bays 101.

[0089] Those skilled in the art should understand that, although the figure shows two battery swap bays 101 being parallel and opposite to each other, the two battery swap bays 101 may alternatively be arranged in other ways, such as at a certain angle to each other, as long as they can form a battery swap parking area 105 between them.

[0090] In other embodiments, the battery swap station 100 may also include only one battery swap bay 101 or more than three battery swap bays 101 for battery replacement.

[0091] In this embodiment, the battery swapping station 100 further includes a charging bin 115, which is arranged above the battery swapping parking area 105 and is used to store batteries.

[0092] In other embodiments, the charging bin 115 can also be arranged in other ways according to needs, such as being arranged below, on the side, etc. relative to the battery swapping parking area 105.

[0093] As Figure 3 shown, a charging rack 116 and the like are arranged in the charging bin, and the battery is placed on the charging rack 116 for charging.

[0094] In this embodiment, the charging bin 115 is arranged above the battery swapping parking area 105 and between two battery swapping bins 101. The charging bin 115 and the two battery swapping bins 101 form a "pin" - shaped structure and surround the battery swapping parking area 105.

[0095] In this embodiment, the following transportation device is further arranged in the battery swapping bin 101. The transportation device is used for disassembling, assembling and transporting the battery between the electric vehicle 40 and the charging bin 115.

[0096] The working mode of the battery swapping station 100 is briefly introduced below.

[0097] First, the electric vehicle 40 (battery - swapping vehicle) drives into the battery swapping parking area 105 and stops at the predetermined battery - swapping position in the battery swapping parking area 105. The transportation device in the battery swapping bin 101 operates to remove the old battery in the electric vehicle 40 and transports it to the charging bin 115 for charging. Then, a fully - charged new battery is taken out from the charging bin 115, transported to the electric vehicle 40 and installed on the electric vehicle 40, thus completing the battery - swapping service for the electric vehicle 40, and the electric vehicle 40 drives away.

[0098] The structure of the battery swapping bin 101 in the battery swapping station 100 is described in detail below.

[0099] As Figure 4 shown, the battery swapping bin 101 includes an upper battery swapping bin 103 and a lower battery swapping bin 104 arranged in the vertical direction. The upper battery swapping bin 103 is arranged above the lower battery swapping bin 104. The upper battery swapping bin 103 is arranged on both sides of the charging bin 115 and is directly connected to the charging bin 115. A communication opening is provided on the lower surface of the upper battery swapping bin 103 to communicate with the lower battery swapping bin 104.

[0100] As Figure 5 、 Figure 6As shown, the side of the lower battery exchange compartment 104 is provided with a battery exchange passage 106 and an emergency door device 110, and the top surface of the lower battery exchange compartment 104 is provided with a connecting port 107, which is used for the upper battery exchange compartment 103, and then connected to the charging compartment 115 through the upper battery exchange compartment 103. The interior of the lower battery exchange compartment 104 is provided with a walking area 108, which is used for the transportation device to walk, and the connecting port 107 is connected to the walking area 108. The lower battery exchange compartment also has a monitoring room 109 and a maintenance area 112.

[0101] The battery exchange channel opening 106 is opened and closed by the compartment door 117.

[0102] like Figure 7-10 As shown, the emergency door device 110 includes a door frame 120, a door panel 121 and an automatic opening mechanism 122. The door frame 120 has an emergency passage, which connects the inside and outside of the lower battery swap compartment 104; the door panel 121 is movably connected to the door frame 120, and the door panel 121 can close and open the emergency passage; the automatic opening mechanism 122 is used to open the door panel 121 according to the instructions of the battery swap station 100 or the action of the transportation device. When a battery pack fails, the emergency door device 110 automatically opens the door panel 121 through the automatic opening mechanism 122 to open the lower battery swap compartment 104 and transport the faulty battery out through the transportation device to prevent the faulty battery from being trapped in the battery swap station 100 and causing safety hazards.

[0103] In this embodiment, the automatic opening mechanism 122 can be a push rod lock 131 device, which includes a push rod lock 131 and a lock matching portion 132, wherein the push rod lock 131 is arranged on the door panel 121, and the lock matching portion 132 is arranged on the door frame 120. Of course, optionally, their arrangement positions can also be opposite.

[0104] The automatic opening mechanism 122 uses a push rod lock 131 device to achieve the function of automatic unlocking by physical impact. It has a simple structure and strong reliability. By setting the push rod lock 131 on the door panel 121, when the push rod lock 131 is unlocked by force, the door panel 121 is also forced to move outward to complete the opening.

[0105] The push rod lock 131 has a lock head 142 and a push rod 141 that are linked. The lock matching portion 132 has a lock hole that matches the lock head 142. When the door panel 121 closes the emergency opening, the lock head 142 is locked in the lock hole. The lock head 142 is used to match the lock hole of the lock matching portion 132 to lock the door panel 121, and the push rod 141 is used to control the lock head 142.

[0106] like Fig.14As shown, the push rod 141 is connected to the lock head 142 through a connecting rod 143, one end of the connecting rod 143 is connected to the push rod 141, and the other end of the connecting rod 143 is connected to the lock head 142, and the connecting rod 143 can rotate. When one end of the push rod 141 is pressed, the other end of the push rod is lifted up and one end of the connecting rod 143 is lifted. When the connecting rod 143 rotates, the other end moves downward and pulls the lock head 142 at the same time, and the lock head 142 is forced to shrink and escape from the lock hole to complete unlocking.

[0107] The push rod 141 is arranged on the side of the push rod lock 131 facing the battery swap compartment 101. When the battery pack transport device moves to the door opening position in the battery swap compartment 101 and touches the push rod 141, the push rod 141 is pressed downward by force and drives the lock head 142 to shrink and move out of the lock hole to complete unlocking. At the same time, the door panel 121 is naturally forced to move outward under the impact to complete opening. The battery pack transport device includes a horizontal moving mechanism, a vertical lifting mechanism and a horizontal extension mechanism. The horizontal moving mechanism is used to drive the battery pack transport device to move horizontally in the battery swap compartment 101. The vertical lifting mechanism and the horizontal extension mechanism are used to drive the battery pack to move vertically and horizontally, respectively. After the battery pack transport device removes the faulty battery from the charging compartment 115, it moves through the horizontal moving mechanism and the vertical lifting mechanism to align the battery pack with the emergency door device 110. The horizontal extension mechanism drives the battery pack to extend toward the door panel 121 and hits the push rod 141 at the same time, driving the lock head 142 to withdraw from the lock hole to open the door panel.

[0108] The door panel 121 is hinged to the bottom of the door frame 120, and the door panel 121 can be flipped around the bottom of the door frame 120 toward the outside of the battery swap compartment 101. The transport device hits the inside of the door panel 121 from the inside, and the door panel 121 flips outward and opens.

[0109] like Fig.11 , Fig.12 As shown, in another embodiment of the present invention, the automatic opening mechanism 122 may be an inductive self-opening mechanism, which includes a locking mechanism 151 , an inductive mechanism 152 and a control module 153 .

[0110] The locking mechanism 151 is used to lock or unlock the door panel 121 and the door frame 120; the sensing mechanism 152 is used to detect the position of the transport device; the control module 153 is electrically connected to the sensing mechanism 152 and the locking mechanism 151, and controls the action of the locking mechanism 151 according to the detection result of the sensing mechanism 152.

[0111] When the locking mechanism 151 is in the locked state, the sensing mechanism 152 detects the position of the transport device to determine whether the transport device is in the open door position of the emergency door device 110. If so, a signal is sent to the control module 153. After receiving the signal, the control module 153 controls the locking mechanism 151 to unlock.

[0112] The locking mechanism 151 includes an automatic lock and a lock matching part 132. The automatic lock is installed on the door frame 120, and the automatic lock is electrically connected to the control module 153; the lock matching part 132 is installed on the door panel 121, and the lock matching part 132 is used to cooperate with the automatic lock to achieve locking and unlocking. The automatic lock can automatically lock or unlock according to the control signal sent by the control module 153. At the same time, since the automatic lock needs to be electrically connected to the control module 153 and the motor and other components, setting it on the door frame 120 can avoid difficulties in wiring due to movement. The automatic lock and the lock matching part 132 can achieve locking and unlocking through electromagnetic, mechanical and other methods.

[0113] In this embodiment, the automatic lock and the lock matching part 132 are locked and unlocked by a mechanical structure in which the lock head 142 and the lock hole match. The automatic lock has a lock head 142, and the lock matching part 132 has a lock hole matching the lock head 142. When the door panel 121 closes the emergency opening, the lock head 142 is locked in the lock hole. The door panel 121 is fixed in the door frame 120 by extending the lock head 142 and locking it in the lock hole, and the door panel 121 is unlocked by retracting the lock head 142 and moving it out of the lock hole.

[0114] When the battery swap station 100 detects that a battery failure has occurred, the transport device will find the faulty battery and transport it to the door opening position in the battery swap compartment 101. When the sensing mechanism 152 detects that the transport device is in the door opening position, it will send a trigger signal to the control module 153. The control module 153 will send a control signal to the locking mechanism 151 based on the trigger signal. When the locking mechanism 151 receives the control signal, the lock head 142 will automatically retract and move out of the lock hole, thereby unlocking the door panel 121 and the door frame 120.

[0115] The automatic opening mechanism 122 of this embodiment determines whether to open or close by means of position detection. The sensing device is a position sensor, which can detect whether the transport device is at the door opening position, and can send a trigger signal to the control device to control the locking mechanism 151 to unlock. The position sensor in this embodiment is set on the door frame and can sense whether there is a transport device at the door opening position. In other embodiments, the position sensor can also be set at the door opening position or directly on the transport device.

[0116] The door opening position may be a position where the transport device travels to face the door panel 121, or a position where the transport device is about to travel to face the door panel 121 and is a certain distance away from the door panel 121. Those skilled in the art may set the door opening position as required.

[0117] like Fig.13 As shown, this embodiment also provides a control method for the emergency door device 110 of the battery swap station 100, which includes the following steps:

[0118] S1: A faulty battery pack is detected in the battery swap station 100;

[0119] S2: The transport device transports the faulty battery pack to the emergency door device 110;

[0120] S3: The automatic opening mechanism 122 opens the door panel 121;

[0121] S4: The transport device transports the faulty battery out of the battery swap station 100 through the opening.

[0122] Once a battery pack fails, the transport device will transport the failed battery pack to the emergency door device 110 after the failed battery pack is detected. The automatic opening mechanism 122 of the emergency door device 110 will automatically open the door panel 121, and the transport device will transport the failed battery out to avoid safety hazards.

[0123] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
