[0026] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention are described in further detail below. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0027] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0028] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0029] like Figure 1-Figure 3 As shown, in order to facilitate the opening of the electronic bus stop door 20 and improve the status monitoring of the electronic bus stop sign, this embodiment provides an electronic lock mechanism for the electronic bus stop sign, which includes a box body 10 and a box door 20. The box body 10 serves as the supporting body of the electronic bus stop sign, and a hollow cavity 11 is formed inside it. In actual application, the cavity 11 is used to install electronic equipment required for the electronic bus stop sign to realize its function. The bus stop sign information or advertisement of the electronic bus stop sign can also be replaced on the rear side of the box door 20 after the box door 20 is opened. An opening 12 connected to the cavity 11 is provided on one side of the box body 10 to facilitate the disassembly and assembly of the above-mentioned electronic equipment and the maintenance of the electronic bus stop sign. One side of the box door 20 is hinged to the box body 10 by a hinge, and can swing back and forth between opening and closing the opening 12 with the above-mentioned hinge as the rotation axis.

[0030] The electronic lock mechanism of the electronic bus stop also includes a lock mechanism for keeping the box door 20 closed or open. The lock mechanism includes a lock hook assembly 30 arranged in the cavity 11 and a fastener 40 arranged on the box door 20. Specifically, the lock mechanism includes a first state and a second state. When the lock mechanism is in the first state, the lock hook assembly 30 and the fastener 40 lock and cooperate to close the box door 20 and lock the opening 12. When the lock mechanism is in the second state, the lock hook assembly 30 is separated from the fastener 40, so that the box door 20 can be swung freely relative to the box body 10. The specific structure of the lock hook assembly 30 and the fastener 40 is not limited here. The lock hook assembly 30 and the fastener 40 can cooperate with each other to lock or separate from each other.

[0031] A magnetic attraction component is used to maintain stability between the box door 20 and the box body 10 in a closed state. The magnetic attraction component includes a magnetic block 50 and an electromagnet 60. The electromagnet 60 and the magnetic block 50 are relatively arranged in the cavity 11 and the box door 20. The electromagnet 60 is electrically connected to the external power supply device. In this example, the electromagnet 60 is arranged in the cavity 11, and the corresponding magnetic block 50 is arranged on the box door 20. The purpose is to facilitate the installation of the electromagnet 60. When the external power supply device continuously supplies power to the electromagnet 60, the electromagnet 60 is magnetic and can allow the magnetic block 50 to be adsorbed on the electromagnet 60. When the external power supply device is disconnected from the electromagnet 60, the magnetism of the electromagnet 60 disappears, allowing the magnetic block 50 to be separated from the electromagnet 60. Specifically, the above-mentioned external power supply device can use the power supply connected to the electronic bus stop itself or an external power supply outside the electronic bus stop.

[0032] The induction component provides a control signal for the lock mechanism and the magnetic component. The induction component includes a sensor plate 70 and an electronic control unit. The sensor plate 70 is installed on the outside of the box body 10 and can be set as an infrared sensor device or a card swiping sensor device. The electronic control unit is electrically connected to the lock mechanism, the external power supply device and the induction plate 70 respectively. During the implementation of this solution, the lock mechanism is in the first state, that is, when the box door 20 is locked with the box body 10 and the external power supply device continuously supplies power to the electromagnet 60, the operator can trigger the induction plate 70 to make the induction plate 70 send the corresponding trigger signal to the electronic control unit, so that the electronic control unit converts the trigger signal into a corresponding control signal and transmits the control signal to the lock. Mechanism, when the locking mechanism switches from the first state to the second state, the electric control signal will also transmit the control signal to the external power supply equipment, so that the external power supply equipment stops supplying power to the electromagnet 60, so that the box door 20 can be opened smoothly, solving the problem that the box door 20 is difficult to open when the traditional electronic bus stop adopts an electronic lock. At the same time, even in the case of power failure, the locking mechanism can still remain in the first state, so that the box door 20 can be tightly locked on the box body 10, which is safe and reliable, and can very conveniently realize the opening and closing of the box door 20. By connecting the background equipment with the electric control unit, the opening and closing status of the box door 20 can also be better monitored, thereby improving the safety factor of the electronic bus stop and avoiding the original safety hazards.

[0033] like Figure 5-Figure 6As shown, further, the lock hook assembly 30 includes an electromagnet device 31 and a rotating lock hook 32 for locking the hook box door 20. The electromagnet device 31 is electrically connected to the electronic control unit. The electromagnet device 31 has an electromagnetic shell and an electromagnet core 311 that can move closer to or away from the electromagnetic shell in the vertical direction, so that the electronic control unit can drive and control the electromagnet core 311 to move back and forth in the direction of approaching and moving away from the electromagnet device 31. In this example, the box body 10 has a rectangular structure, and the opening 12 is opened on one side of the box body 10. The rotating lock hook 32 is arranged on the other side wall that is arranged at a right angle to the opening 12 and is parallel to the side wall. The first end of the rotating lock hook 32 is close to the opening 12 and forms a hook body 321 for cooperating with the fastener 40, and the fastener 40 is a rod-shaped structure for the hook body 321 to be hooked. The second end of the rotating lock hook 32 extends in a direction away from the opening 12 and pivots with the electromagnet core 311. Then, the first end and the second end of the rotating lock hook 32 are pivotally connected to the wall of the cavity 11, and the electromagnet device 31 is controlled by the electronic control unit to make the electromagnet core 311 move back and forth in the vertical direction to drive the rotating lock hook 32 to swing around its own pivot point, thereby switching between the first state and the second state. When the electromagnet core 311 rises, the hook body 321 will swing downward to hook the fastener 40, and when the electromagnet core 311 falls, the hook body 321 will rise and disengage from the fastener 40.

[0034] In order to ensure that the rotating lock hook 32 of the box door 20 can automatically reset after being unlocked and separated from the box body 10, and to avoid the box door 20 being unable to re-lock the box body 10 when closing, the lock hook assembly 30 also includes a reset spring 33, one end of the reset spring 33 is hung on the first end of the rotating lock hook 32, and the other end of the reset spring 33 is located at the lower part of the rotating lock hook 32 and hung on the wall of the cavity 11, and continuously applies a downward pulling force to the first end of the rotating lock hook 32, so that the rotating lock hook 32 continues to remain in the first state in the absence of external force, so that the hook body 321 can be more stable during the process of hanging the fastener 40, thereby preventing the box door 20 from falling off the box body 10.

[0035] like Figure 7-Figure 8 As shown, in order to prevent the box door 20 from being unable to be unlocked in the event of a power outage, the lock hook assembly 30 also includes a manual lock 80 and a lock tongue 81. The manual lock 80 is arranged on the box body 10, and one end of the manual lock 80 forms a manual trigger end. The trigger end can be set to a lock hole or a twist lock or other component that can manually open the lock. The other end of the manual lock 80 can be movably inserted into the cavity 11 and connected to the lock tongue 81. The lock tongue 81 is set on one side of the cavity 11 close to the second end of the rotating lock hook 32. By triggering the manual lock 80, the lock tongue 81 can move back and forth between the second end close to or away from the release rotating lock hook 32. In the event of an accidental power outage or the electronic bus stop is in a non-working state, the manual lock 80 can be driven by operating the trigger section, and the lock tongue 81 will rotate by toggling the rotating lock hook 32 to open the box door 20.

[0036] In order to improve the overall installation stability of the lock hook assembly 30, the lock hook assembly 30 also includes a support plate 34, which is arranged on the wall surface of the cavity 11 and forms a accommodating cavity 341 between the support plate 34 and the wall surface of the cavity 11. The rotating lock hook 32 is movably placed in the accommodating cavity 341, and the side wall of the cavity 11 and the support plate 34 jointly support the rotating lock hook 32. In this example, a pivot hole is opened in the middle of the rotating lock hook 32, and a rotating gasket 323 is provided in the pivot hole. The thickness of the rotating gasket 323 is slightly larger than the thickness of the rotating lock hook 32, ensuring that the rotating lock hook 32 can rotate flexibly in the accommodating cavity 341 without getting stuck or offset. In order to further limit the freedom of movement of the rotating lock hook 32, a limiting plate 324 is provided between the rotating lock hook 32 and the side wall of the cavity 11, so that the rotating lock hook 32 can rotate in the limiting plate 324. Since the rotating lock hook 32 is installed on a side closer to the support plate 34 , the other end of the return spring 33 in this example is also hung on a side of the support plate 34 closer to the accommodating cavity 341 .

[0037] Furthermore, a door opening limit shaft 342 and a door closing limit shaft 343 are provided on one side of the support plate 34 located within the accommodating cavity 341. The door opening limit shaft 342 is disposed above the first end of the rotating lock hook 32, while the door closing limit shaft 343 is disposed below the first end of the rotating lock hook 32. The rotating lock hook 32 can only rotate between the door closing limit shaft 343 and the door opening limit shaft 342. When the locking mechanism is in the first state, the rotating lock hook 32 abuts against the door closing limit shaft 343. When the locking mechanism is in the second state, the rotating lock hook 32 abuts against the door opening limit shaft 342, thereby preventing the rotating lock hook 32 from moving beyond its range and causing damage to the locking mechanism.

[0038] In order to make the box door 20 easier to open, a limit switch 35 is also provided in the accommodating chamber 341. The limit switch 35 is arranged at the lower part of the second end of the rotating lock hook 32 and is electrically connected to the electronic control unit. The limit switch 35 has a trigger spring 351 for triggering the limit switch 35. In this example, a pressure rod 322 protrudes outward from the connection point where the second end of the rotating lock hook 32 is connected to the electromagnet core 311. The pressure rod 322 is used to press the trigger spring 351 when the second end of the rotating lock hook 32 moves toward the trigger spring 351. When the lock mechanism is in the first state, the rotating lock hook 32 is away from the trigger spring piece 351. When the lock mechanism is in the second state, the rotating lock hook 32 is close to the trigger spring piece 351. In the actual application of this solution, when the operator triggers the sensing plate 70, the electromagnet device 31 pulls the electromagnet core 311 to move downward, and the second end of the rotating lock hook 32 moves downward with the electromagnet core 311, so that the hook body 321 of the first end of the rotating lock hook 32 is upwardly separated from the buckle 40, thereby switching the lock mechanism from the first state to the second state. In this process, the rotating lock hook 32 The second end of the lever 350 will move toward the trigger spring piece 351 and press against the trigger spring piece 351, so that the limit switch 35 is triggered. Then, the switch formed will transmit the trigger signal to the electronic control unit, and the electronic control unit will convert the trigger signal into a corresponding control signal and transmit it to the external power supply device, so that the external power supply device stops supplying power to the electromagnet 60, causing the electromagnet 60 to lose its magnetism. In this way, the locking mechanism and the magnetic attraction component will simultaneously break away from the restriction on the door 20, so that the door 20 can be in a free swinging state, making the door 20 more stable and convenient to open.

[0039] like Figure 4 As shown, further, a through hole 51 is opened on the magnetic block 50, and an ejection assembly is arranged in the through hole 51. The ejection assembly can eject the box door 20 away from the box body 10 at the moment when the electromagnet 60 loses its magnetism. In this example, a pad is also provided between the magnetic block 50 and the box door 20 to facilitate the installation of the magnetic block 50 and the ejection assembly, which can prevent the box door 20 from being accidentally re-locked when the locking mechanism returns to the first state, and allow the box door 20 to automatically open for the operator to perform subsequent operations.

[0040] Specifically, the ejection assembly includes a ejection block 52 and a spring 53. A boss 511 is provided on the hole wall of the through hole 51 at one end away from the box door 20. A clamping platform 521 that can abut against the boss 511 is provided on the outer periphery of the ejection block 52. When the clamping platform 521 abuts against the boss 511, the ejection block 52 protrudes from the surface of the magnetic block 50. The spring 53 is provided between the ejection block 52 and the box door 20, and the opposite ends of the spring 53 abut against the ejection block 52 and the box door 20 respectively. Because the upper and lower electromagnets 60 attract the door 20, eliminating the elastic force in the door's opening direction, and there is no significant force between the rotating lock hook 32 and the fastener 40, after the sensor plate 70 is triggered, the electromagnet core 311 controlled by the electronic control unit moves downward. In this example, the electromagnet core 311 drives the rotating lock hook 32 to rotate via the transmission rod. When the rotating lock hook 32 rotates to the position of the door opening limit shaft 342, it also triggers the limit switch 35. At this time, the limit switch 35 circuit is disconnected, the electromagnet 60 is de-energized, and the door 20 automatically springs open under the action of the elastic force. After a period of time, the electromagnet 60 and the rotating lock hook 32 will automatically reset.

[0041] In order to improve the monitoring level of the electronic bus stop door 20, the induction component also includes an induction magnet 91 and a Hall sensor 90. The induction magnet 91 and the Hall sensor 90 are respectively placed in the cavity 11 and the door 20. The Hall sensor 90 is electrically connected to the electronic control unit. The Hall sensor 90 on the box body 10 transmits a signal to the electronic control unit by sensing the induction magnet 91 on the door 20. The background equipment is connected to the electronic control unit and can determine whether the door 20 is locked through the background equipment. When the Hall sensor 90 and the induction magnet 91 are almost in contact, it indicates that the door 20 is normally locked; when the induction magnet 91 is away from the Hall sensor 90, it indicates that the door 20 is open.
