DETAILED DESCRIPTION

[0046] The following description is used to disclose the present application to enable a person skilled in the art to implement the present application. The preferred embodiments in the following description are only as examples, and other obvious modifications can be conceived by those skilled in the art.

[0047] As shown in Figures 1 to 10 A power connector of a battery replacement cabinet, comprising:

[0048] An insulating shell 1, a conductive connector 2 is slidably connected in the insulating shell 1, and a first energy storage spring 3 is fixedly connected between the conductive connector 2 and the connecting shell;

[0049] An insulating slot 4 adapted to the outer contour of the battery interface is formed at the end of the insulating shell 1 and the end of the conductive connector 2, and a temperature sensor 6 is arranged in the insulating slot 4 for detecting the temperature of the conductive connector 2;

[0050] A first self-locking mechanism for limiting the position of the conductive connector 2 in the insulating shell 1;

[0051] A controller, based on the temperature parameter detected by the temperature sensor 6, when the temperature parameter exceeds the threshold value, the controller controls the first self-locking mechanism to close, cancels the limiting of the conductive connector 2, and under the elastic action of the first energy storage spring 3, drives the conductive connector 2 to move, so that the conductive connector 2 is separated from the battery interface;

[0052] Wherein the tail end of the conductive connector 2 is connected with the power cord;

[0053] Specifically, in the prior art, during the charging of the battery, the battery is in a closed space, the internal air flow is poor, and the battery is easy to heat. The existing overcharge protection usually adopts electronic fuse or alarm prompt, but the connector still maintains physical connection, which is easy to cause incomplete power-off and safety hazards. The technical solution can solve the above problems, and the specific operation is as follows:

[0054] The conductive connector 2 is connected with the interface of the battery, and the outer contour of the battery interface is inserted into the insulating slot 4, then the battery is placed into the battery replacement cabinet, and the door is closed, and the battery is charged through the conductive connector 2;

[0055] During the charging, the temperature of the battery interface is detected in real time by the temperature sensor 6, and when the temperature of the interface exceeds the specified threshold value, the first self-locking mechanism is closed by the controller, so that the limiting of the conductive connector 2 is cancelled;

[0056] Under the elastic action of the first energy storage spring 3, the conductive connector 2 moves away from the battery interface, so that the conductive connector 2 is separated from the battery interface, and the insulating shell 1 is not separated from the interface, which ensures that the battery is fully powered off and avoids safety hazards.

[0057] As a further embodiment of the present application, further comprises:

[0058] The driving motor 7 is fixedly connected to the inner wall of the top end of the insulating shell 1, and the output shaft of the driving motor 7 is fixedly connected with a first gear 87, the side surface of the first gear 87 is engaged with a first rack 9, the first rack 9 is slidingly connected to the outer wall of the insulating and conductive connector 2, and the first rack 9 is fixedly connected with a let spring 10 between the insulating and conductive connector 2;

[0059] The controller controls the driving motor 7 to start when the temperature parameter detected by the temperature sensor 6 is less than a threshold value, so that the conductive connector 2 is reconnected with the battery interface.

[0060] The driving motor 7 is a non-self-locking motor.

[0061] Specifically, after the conductive connector 2 is separated from the battery interface, the temperature sensor 6 continues to detect the temperature at the interface, and when the temperature at the interface is lower than a specified threshold value, the controller starts the driving motor 7, so that the output shaft of the driving motor 7 rotates, the first gear 87 rotates, and the first rack 9 moves, under the connection of the let spring 10, the conductive connector 2 moves, and is reconnected with the battery interface, restoring the charging of the battery. In the process of moving the conductive connector 2, the first energy storage spring 3 is compressed, and energy is stored for the next time when the conductive connector 2 is separated from the interface.

[0062] After the conductive connector 2 is connected with the interface, the first rack 9 continues to move, so that the let spring 10 is compressed, thereby facilitating the normal connection of the conductive connector 2 with the interface.

[0063] As a further embodiment of the present application, the first self-locking mechanism comprises:

[0064] The first ratchet wheel 11 is coaxially fixed with the first gear 87.

[0066] The first flip drive assembly is used to drive the first pawl 12 to flip to cancel the limiting of the first ratchet wheel 11.

[0067] The first flip drive assembly comprises a first magnet block 14 fixedly connected to the side wall of the first pawl 12, and a first electromagnet 15 fixedly connected to the position corresponding to the first magnet block 14 on the inner wall of the top end of the insulating shell 1.

[0068] Specifically, by setting the first ratchet wheel 11 and the first pawl 12, when the conductive connector 2 is connected with the interface, the first pawl 12 is clamped on the side of the first ratchet wheel 11, thereby limiting the rotation of the first ratchet wheel 11, thereby limiting the rotation of the first gear 87, and since the first gear 87 is engaged with the first rack 9, the position of the conductive connector 2 is limited;

[0069] When the temperature at the interface exceeds the threshold value, the controller turns on the circuit of the first electromagnet 15, so that the first electromagnet 15 generates a magnetic force different from the first magnet block 14, and since opposite poles attract each other, the first pawl 12 is flipped, the limiting of the first ratchet wheel 11 is cancelled, and under the action of the first energy storage spring 3, the conductive connector 2 is quickly separated from the interface, ensuring that the battery is fully disconnected, and avoiding safety hazards;

[0070] During the flipping of the first pawl 12, the torsional spring generates elastic force, and after the conductive connector 2 is separated from the interface, the controller turns off the circuit of the first electromagnet 15, so that the first electromagnet 15 loses the magnetic force, and under the action of the torsional spring, the first pawl 12 is reset and re-clamped with the first ratchet wheel 11;

[0071] After the temperature of the interface returns to normal (below the specified threshold value), the controller starts the driving motor 7, and performs the above operation, so that the first gear 87 rotates, the first ratchet wheel 11 rotates, and finally the conductive connector 2 is reconnected with the interface, and then the first pawl 12 limits the first ratchet wheel 11, thereby re-limiting the position of the conductive connector 2, ensuring that the conductive connector 2 is normally connected with the interface.

[0074] A second self-locking mechanism is used to limit the push rod 17;

[0075] A voltage sensor is used to detect the voltage of the battery;

[0076] The controller controls the second self-locking mechanism to be closed when the voltage value detected by the voltage sensor reaches a specified value, thereby cancelling the limiting of the push rod 17;

[0077] Specifically, by setting the voltage sensor, when the battery is close to full charge, the voltage will reach a peak, for lead-acid batteries, the full charge voltage is usually around 12.6-12.8V, and for lithium battery monomer, it is around 4.2V, when the voltage reaches the preset threshold, the controller controls the second self-locking mechanism to close, cancels the limit of the push rod 17, under the action of the second energy storage spring 19, the push rod 17 extends out of the sliding groove 16, and the battery is extruded by pushing the outer wall, so that the insulating shell 1 is separated from the interface, so that the conductive connector 2 is separated from the interface, on the one hand, it ensures that the power is fully disconnected, avoids causing safety hazards, on the other hand, the user does not need to manually pull out the power supply, and the battery can be quickly taken out of the battery compartment.

[0078] It should be noted that the controller and the voltage sensor are arranged in the battery compartment.

[0085] Specifically, by setting the second ratchet wheel 22 and the second pawl 23, in the process of inserting the insulating shell 1 into the battery interface, the push rod 17 is in contact with and extruded by the outer wall of the battery, so that the push rod 17 is retracted into the sliding groove 16, and the second energy storage spring 19 is compressed and stored energy;

[0086] In the process of retracting the push rod 17 into the sliding groove 16, the second rack 20 is engaged with the second gear 21, so that the second gear 21 rotates, the second ratchet wheel 22 rotates, and the second pawl 23 limits the second ratchet wheel 22, thereby limiting the push rod 17, and ensuring that the insulating shell 1 is stably connected with the interface;

[0087] When the voltage sensor detects that the voltage in the battery reaches a specified value, the controller turns on the circuit of the second electromagnet 26, so that the second electromagnet 26 generates a magnetic force different from the second magnet block 25, under the attraction of the second magnet block 25, so that the second ratchet wheel 22 is flipped, the limiting of the second ratchet wheel 22 is cancelled, thereby cancelling the limiting of the second gear 21, under the action of the second energy storage spring 19, the push rod 17 is quickly extended from the sliding groove 16, and the battery outer wall is extruded, so that the insulating shell 1 is separated from the interface;

[0088] After the insulating shell 1 is separated from the interface, the controller turns off the circuit of the second electromagnet 26, under the action of the second torsional spring 24, the second pawl 23 is reset and re-coupled with the second ratchet wheel 22.

[0089] As a further embodiment of the present application, a plurality of elastic clamping pieces 5 are symmetrically and fixedly connected to the inner wall of the insulating slot 4.

[0095] Under the elastic action of the first energy storage spring 3, the conductive connector 2 moves away from the battery interface, so that the conductive connector 2 is separated from the battery interface, and the insulating shell 1 is not separated from the interface, thereby ensuring that the battery is fully powered off and avoiding safety hazards;

[0096] After the electrically-conductive connector 2 is separated from the battery interface, the temperature sensor 6 continues to detect the temperature at the interface. When the temperature at the interface is lower than a specified threshold, the controller starts the driving motor 7, so that the output shaft of the driving motor 7 rotates, and the first gear 87 rotates, thereby driving the first rack 9 to move, and under the connecting action of the displacement spring 10, the electrically-conductive connector 2 moves, re-connects with the battery interface, and resumes charging the battery. In the process of moving the electrically-conductive connector 2, the first energy storage spring 3 is compressed, and energy is stored, so as to prepare for the next time when the electrically-conductive connector 2 is separated from the interface.

[0097] After the electrically-conductive connector 2 is connected with the interface, the first rack 9 continues to move, so that the displacement spring 10 is compressed, thereby facilitating ensuring that the electrically-conductive connector 2 is normally connected with the interface.
