[0038] A kind of battery replacement unlocking device provided by this application, refer to Figures 1-6 , in some embodiments, the battery replacement unlocking device includes a vehicle frame bottom bracket, an electromagnet assembly device 3 and a control system. The electromagnet assembly device 3 is installed inside the vehicle frame bottom bracket. The electromagnet assembly device 3 includes an electromagnet and a permanent magnet, and the permanent magnet is at least partially sleeved on the outer periphery of the electromagnet;

[0039] The control system includes a power supply. The control system is electrically connected to the electromagnet. The control system controls the power supply to supply power to the electromagnet so that the electromagnet attracts, or controls the power supply to disconnect the power supply to the electromagnet so that the electromagnet disconnects.

[0040] Specifically, the frame bottom bracket includes a bottom bracket upper beam 2 and a bottom bracket lower beam 1. The bottom bracket lower beam 1 is sleeved outside the bottom bracket upper beam 2, and there is a cavity between the bottom bracket upper beam 2 and the bottom bracket lower beam 1. The electromagnet assembly device 3 includes an assembly upper cover 4 and an assembly main body 5. The assembly main body 5 is installed inside the assembly upper cover 4. The assembly main body 5 includes a first frame 6, a second frame 7 and an internal structure. The first frame 6 and the second frame 7 are arranged side by side horizontally, and the middle part of the contact surface between the first frame 6 and the second frame 7 is embossed and riveted, and at the same time, the rest of the contact surface between the first frame 6 and the second frame 7 is welded. One end of the first frame 6 away from the second frame 7 is connected to the internal structure by four rivets, and one end of the second frame 7 away from the first frame 6 is connected to the internal structure by three M3 screws.

[0041] The internal structure includes a moving valve core 8, a pressing plate 9, a permanent magnet, a coil 11, a spring 12, a push rod 13 and a static iron core 14. The electromagnet includes a moving valve core 8, a static iron core 14, a coil 11 and a spring 12. The static iron core 14 is fixedly installed at one end of the first frame 6 close to the second frame 7. The moving valve core 8 is also installed in the first frame 6, and there is a gap between the moving valve core 8 and the static iron core 14. One end of the moving valve core 8 is connected to one end of the push rod 13. The other end of the push rod 13 passes through the first frame 6 and is installed in the second frame 7. The coil 11 is installed outside the moving valve core 8 and the static iron core 14. The spring 12 is arranged inside the coil 11. The permanent magnet includes a first permanent magnet 10 and a second permanent magnet 15. The first permanent magnet 10 is arranged on the outer periphery of one end of the moving valve core 8 away from the static iron core 14. The pressing plate 9 is arranged at the outer end of the first permanent magnet 10. The second permanent magnet 15 is arranged in the second frame 7.

[0042] The battery replacement unlocking device is installed inside the frame bottom bracket and fixed by M3 countersunk head bolts. The battery replacement unlocking device itself is provided with M4 threaded holes, and the number of unilateral fixing points is not less than three. The overall height limit dimension of the battery replacement unlocking device is 30 mm, the width limit dimension is 49 mm, and the limit length from the front end to the tail end is 140 mm.

[0043] When the control system supplies power to the electromagnet and controls the electromagnet to attract, that is, the moving valve core 8 of the electromagnet approaches the static iron core 14 under the action of magnetic force, and the spring 12 is compressed. When the gap distance between the moving valve core 8 and the static iron core 14 is 0 mm - 3 mm, the moving valve core 8 drives the fixing device magnetically connected to the vehicle battery to move, so that the fixing device is disconnected from the battery, thereby unlocking the vehicle battery. At this time, the vehicle battery can be taken out and replaced; when the control system controls the electromagnet to disconnect, that is, there is no magnetic force between the moving valve core 8 and the static iron core 14. At this time, the moving valve core 8 moves away from the static iron core 14 under the action of the spring 12. When the gap distance between the moving valve core 8 and the static iron core 14 is 12 mm - 15 mm, the moving valve core 8 drives the fixing device to move, so that the fixing device is magnetically connected to the battery, thereby locking the vehicle battery. At this time, the newly replaced vehicle battery can be fixed to prevent the vehicle battery from falling off; when the gap distance between the moving valve core 8 and the static iron core 14 is 3 mm - 12 mm, no action is taken.

[0044] The battery replacement unlocking device provided by this application, by setting the first permanent magnet 10 and the second permanent magnet 15, can reduce the volume of the electromagnet under the condition of ensuring the magnetic force of the electromagnet assembly device 3, that is, under the same magnetic force condition, the overall volume of the first permanent magnet 10, the second permanent magnet 15 and the electromagnet is smaller than that of the traditional electromagnet. Therefore, the space occupied by the electromagnet assembly device 3 is reduced, so that the electromagnet assembly device 3 can be installed in the narrow frame bottom bracket.

[0045] In addition, the electromagnet has a small volume and is powered by a common 24V power supply mode. Therefore, the battery replacement unlocking device provided by this application can be applied to other systems that require electromagnetic force and signal acquisition.

[0046] Optionally, other types of screws or countersunk bolts can also be selected for fixing according to the actual situation.

[0047] Optionally, other gap distances between the moving valve core 8 and the static iron core 14 can also be set to lock or unlock.

[0048] Optionally, the limit size of the battery replacement unlocking device can also be set according to the space size in the frame bottom bracket.

[0049] In some embodiments, the electromagnet assembly device 3 further includes a circuit board 16. The circuit board 16 is provided with a switch, and the switch is electrically connected to the installation device for installing the vehicle battery;

[0050] The output port of the electromagnet is connected to the switch to control the unlocking or locking of the installation device.

[0051] Specifically, a circuit board 16 is provided inside the second frame 7. A switch is provided on the circuit board 16. The low-voltage interface 20 of the electromagnet includes three input ports and an output port. The first input port 21 is connected to the vehicle battery in the control system. The second input port 22 is grounded. The third input port 23 is connected to the control terminal of the ECU (Electronic Control Unit) in the control system. The output port of the electromagnet is connected to the switch on the circuit board 16.

[0052] When the ECU control terminal outputs a high level, the electromagnet is attracted and the installation device is lifted through the switch, that is, the installation device is unlocked, and at this time, the vehicle battery can be removed for replacement. When the ECU control terminal outputs a low level, the electromagnet is disconnected and the installation device is lowered through the switch, that is, the installation device is locked, and at this time, the vehicle battery can be fixed.

[0053] Integrating the switch on the circuit board 16, compared with the prior art where the switch and the circuit board 16 are separately arranged, the volume can be reduced, thereby reducing the space occupied by the overall battery replacement unlocking device. At the same time, the integrated structure design of the switch and the circuit board 16 can reduce the overall installation error of the battery replacement unlocking device and improve reliability.

[0054] In addition, the current of the coil 11 can be reduced through the circuit board 16, thereby reducing the time consumption when the electromagnet works. And since the current of the coil 11 is small in the stable attraction state, the heat generated by the electromagnet is small. Therefore, it can work for a long time, improve the overall service life of the device, and extend the usage frequency and life of the whole battery replacement vehicle.

[0055] In some embodiments, the electromagnet assembly device 3 further includes a disconnection sensing device. The switch includes a first switch and a second switch. The disconnection sensing device is used to sense the position where the electromagnet is in the disconnected state.

[0056] The disconnection sensing device, the first switch, and the second switch are all electrically connected to the control system.

[0057] The disconnection sensing device is configured to control the first switch to disconnect and the second switch to connect when the electromagnet is in the disconnected state.

[0058] Specifically, the disconnection sensing device is arranged inside the second frame 7. One end of the ejector rod 13 connected to the moving valve core 8 passes through the first frame 6 and is arranged inside the second frame 7. The disconnection sensing device is used to sense the position of the ejector rod 13. The disconnection sensing device is set at the position where the ejector rod 13 is inside the second frame 7 when the electromagnet is disconnected, that is, when the gap distance between the moving valve core 8 and the static iron core 14 is 13 mm - 15 mm, the position where the end of the ejector rod 13 inside the second frame 7 is located is the position where the disconnection sensing device is set.

[0059] The output ports of the electromagnet include a first output port 24 and a second output port 25. The first output port 24 is connected to the first switch, and the second output port 25 is connected to the second switch.

[0060] The control system includes an ECU control terminal, an input interface circuit, an MCU (Microcontroller Unit), an LDO (Low Dropout Regulator) power module, an electromagnetic pole conversion circuit, an output interface circuit, a first MOS (Metal Oxide Semiconductor Field Effect Transistor) transistor switch circuit, and a second MOS transistor switch circuit. The ECU control terminal is connected to the input interface circuit, the input interface circuit is connected to the MCU, the MCU is respectively connected to the LDO power module, the electromagnetic pole conversion circuit, and the output interface circuit. The electromagnetic pole conversion circuit is connected to the coil 11, the first MOS transistor switch circuit is connected to the first switch, the second MOS transistor switch circuit is connected to the second switch, and the disconnection induction device is disconnected from the input interface circuit.

[0061] The input interface circuit is a switch circuit designed with transistors, which converts the external signal voltage into the standard voltage of the MCU's IO port. The switch circuit converts into a high level of 5V and a low level of 0V as the external voltage changes; the LDO power module adjusts the voltage input from the vehicle's main battery to within the working voltage range of the MCU; the electromagnetic pole conversion circuit is a bridge circuit composed of a transistor array. By controlling the input end of the transistor through the MCU, the current direction in the transistor bridge circuit is converted, thereby changing the current direction of the coil 11, and further changing the magnetic pole direction of the coil 11; the output interface circuit is the same as the input interface circuit, both are transistor switch circuits, but the connection method of the output interface circuit is opposite to that of the input interface circuit; the first MOS transistor switch circuit and the second MOS transistor switch circuit are both low-end output circuits composed of high-current MOS transistors.

[0062] When the MCU receives a low level input from the ECU control terminal through the input interface circuit, if the disconnection induction device detects the end of the push rod 13 at this time, that is, the electromagnet is in the off state, the moving valve core 8 does not move; if the disconnection induction device does not detect the end of the push rod 13, that is, the electromagnet is not in the off state, the moving valve core 8 moves away from the static iron core 14 under the action of the spring 12, that is, the disconnection action is executed. The MCU judges the input signal of the disconnection induction device during the disconnection process. When the disconnection induction device senses the push rod 13, it controls the first switch to disconnect and the second switch to connect, and controls the locking of the installation device through the second switch.

[0063] By setting up a disconnection sensing device, the accuracy of detecting whether the electromagnet is in a disconnected state can be improved, thereby enhancing the overall reliability of the electromagnet.

[0064] Optionally, the disconnection sensing device can also be arranged within the first frame 6 to directly sense the position of the moving spool valve 8.

[0065] In some embodiments, the electromagnet assembly device 3 further includes an attraction sensing device electrically connected to the control system, and the attraction sensing device is configured to control the first switch to be turned on and the second switch to be turned off when the electromagnet is in an attracted state.

[0066] Specifically, the attraction sensing device is arranged within the second frame 7 and at the position of the end of the ejector rod 13 within the second frame 7 when the electromagnet is in an attracted state, that is, when the gap distance between the moving spool valve 8 and the static iron core 14 is 0 mm - 3 mm, the position of the end of the ejector rod 13 within the second frame 7 is the position where the attraction sensing device is set.

[0067] When the MCU receives a high level input through the input interface circuit from the ECU control terminal, if the attraction sensing device detects the end of the ejector rod 13 at this time, that is, the electromagnet is in an attracted state, the moving spool valve 8 does not move; if the attraction sensing device does not detect the end of the ejector rod 13, that is, the electromagnet is not in an attracted state, the moving spool valve 8 moves in the direction close to the static iron core 14 under the action of magnetic force, that is, performs an attraction action. The MCU judges the input signal of the attraction sensing device during the attraction process. When the attraction sensing device senses the ejector rod 13, it controls the first switch to be turned on, the second switch to be turned off, and controls the unlocking of the installation device through the first switch.

[0068] By setting up the attraction sensing device, the accuracy of detecting whether the electromagnet is in an attracted state can be improved, thereby further enhancing the overall reliability of the electromagnet.

[0069] Optionally, the attraction sensing device can also be arranged within the first frame 6 or other positions.

[0070] In some embodiments, the disconnection sensing device is arranged on the circuit board 16, and / or the attraction sensing device is arranged on the circuit board 16.

[0071] Specifically, both the disconnection sensing device and the attraction sensing device are integrated on the circuit board 16, which can further reduce the overall volume of the battery replacement unlocking device, thereby further ensuring that the battery replacement unlocking device can be installed inside the frame bottom bracket. At the same time, integrating the disconnection sensing device and the attraction sensing device on the circuit board 16 can improve the reliability of signal detection, reduce the failure rate of the switch, and thus enhance the overall reliability of the electromagnet.

[0072] Optionally, the disconnection sensing device and the attraction sensing device can also not be arranged on the circuit board 16.

[0073] In some embodiments, the disconnection sensing device is an optocoupler sensor, and / or the attraction sensing device is an optocoupler sensor.

[0074] Specifically, both the disconnection sensing device and the attraction sensing device are optocoupler sensors. Since the disconnection sensing device and the attraction sensing device are arranged near the electromagnet and the permanent magnet, using optocoupler sensors can enhance the anti-interference ability of the disconnection sensing device and the attraction sensing device to electromagnetic interference, thereby avoiding problems in the detection results caused by electromagnetic interference to the disconnection sensing device and the attraction sensing device, and further improving the reliability of signal detection.

[0075] Optionally, other sensors can also be used as the disconnection sensing device and the attraction sensing device, and an anti-interference structure is arranged outside the disconnection sensing device and the attraction sensing device.

[0076] In some embodiments, a protective housing for protecting the circuit board 16 is provided outside the circuit board 16.

[0077] Specifically, the protective housing includes a protective upper cover 18 and a protective lower cover 19. The protective upper cover 18 and the protective lower cover 19 cover the outside of the circuit board 16, thereby preventing dust from entering the circuit board 16. At the same time, the overall design is of the protection level IP6K7K, ensuring absolute dust protection of the circuit board 16 and preventing dust from entering the circuit board 16 and affecting each device on the circuit board 16, thereby extending the service life of the circuit board 16.

[0078] Optionally, it can also be designed with other protection levels.

[0079] In some embodiments, an epoxy resin glue structure is provided inside the circuit board 16.

[0080] Specifically, the inside of the circuit board 16 is potted with epoxy resin glue to ensure absolute waterproofing inside the circuit board 16, prevent the circuit board 16 from being damaged due to water ingress, and further extend the service life of the circuit board 16.

[0081] Optionally, other waterproof structures can also be provided.

[0082] In some embodiments, a dust-proof ring 17 is provided outside the electromagnet, and the permanent magnet is arranged outside the dust-proof ring 17.

[0083] Specifically, the first permanent magnet 10 is sleeved outside the moving spool 8, and a dust-proof ring 17 is provided between the first permanent magnet 10 and the moving spool 8. A dust-proof ring 17 is also provided at one end of the static iron core 14 close to the second frame 7, thereby preventing dust from entering the inside of the electromagnet and avoiding blockage inside the electromagnet caused by dust, which may lead to abnormal disconnection or attraction of the electromagnet.

[0084] Optionally, other numbers of dust-proof rings 17 can also be set.

[0085] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0086] The above-described embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
