Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model. In the utility model, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0050] Please refer to Figure 1-Figure 3 , Figure 1 is a schematic diagram of the structure of a lock provided by an embodiment of the utility model, Figure 2 yes Figure 1 Partial structure diagram of the provided lock Figure 1 , Figure 3 yes Figure 1 An exploded diagram of the provided lock. The present application provides a lock 100, which includes a housing 10 and a lock beam 20, wherein the housing 10 includes a base and a side wall 12, wherein the base includes a bottom wall 11, and the side wall 12 is arranged around the bottom wall 11 and forms a receiving chamber 101, wherein a portion of the lock beam 20 can extend into the receiving chamber 101. The lock 100 also includes a conversion member 30, which is arranged in the receiving chamber 101 and is used to cooperate with the lock beam 20 to achieve unlocking or locking of the lock 100. It can be understood that the lock 100 also includes a spring, which is connected to the bottom of the lock 100, and when the conversion member 30 cooperates with the lock beam 20 to lock, the spring is compressed, and when the conversion member 30 cooperates with the lock beam 20 to unlock, the lock beam 20 pops up under the action of the spring to complete the unlocking.

[0051] The lock 100 further includes a motor 40, a mechanical lock core 50 and a control assembly 60. The motor 40 is disposed in the accommodating chamber 101. The motor 40 can drive the conversion member 30 to move so as to unlock or lock the lock beam 20. The mechanical lock core 50 is disposed in the accommodating chamber 101. The side wall 12 is provided with a through hole 121 corresponding to the lock hole of the mechanical lock core 50. The mechanical lock core 50 can drive the conversion member 30 to rotate so as to unlock or lock the lock beam 20. The control assembly 60 includes an NFC antenna 61 and a control circuit board 62. The NFC antenna 61 cooperates with the control circuit board 62 to control the motor 40. The NFC antenna 61 is attached to the bottom wall 11.

[0052] In the prior art, the mechanical lock cylinder 50 is unlocked from the bottom, that is, the bottom wall 11 is provided with a through hole 121 corresponding to the lock hole of the mechanical lock cylinder 50, and when the NFC antenna 61 is arranged on the bottom wall 11, it needs to avoid the through hole 121, so the layout space of the NFC antenna 61 is limited and the NFC antenna 61 cannot be effectively arranged. When the lock hole faces the side wall 12 and the NFC antenna 61 is attached to the bottom wall 11, the mechanical lock cylinder can be unlocked from the side wall 12, so that there is more space at the bottom of the lock to accommodate the NFC antenna 61, which is convenient for the placement of the NFC antenna 61, and avoids the keyhole being inserted into the bottom of the lock to unlock and overlapping with the layout of the NFC antenna, thereby solving the technical problem of unreasonable layout of the electronic unlocking structure and the mechanical unlocking structure.

[0053] Specifically, NFC (Near Field Communication, NFC) is also known as short-range wireless communication, which is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission and exchange of data between electronic devices. NFC communication adopts electromagnetic induction, and after the NFC antenna 61 receives the carrier from the reader, the information is processed through the chip. The NFC antenna 61 includes a magnetic element and a coil attached to the magnetic element, and a protective cover covering the coil, wherein the coil can be a circular coil or an elliptical coil.

[0054] The control circuit board 62 can be a flexible circuit board (FPC), the control circuit board 62 can also be a rigid circuit board (PCB), and the control circuit board 62 can also be a flexible and rigid combination board (FPCB). The embodiment of the present application does not limit this. The control circuit board 62 can be provided with a control unit, a data communication unit, and an energy storage unit, etc.

[0055] The NFC antenna 61 is electrically connected to the control circuit board 62, and the NFC antenna is used to transmit energy and / or information. In other words, the NFC antenna can be used only to transmit energy, the NFC antenna can be used only to transmit information, or the NFC antenna can be used to transmit both energy and information, which is not limited in the embodiments of the present application.

[0056] The control assembly 60 also includes an energy storage component connected to the control circuit board 62, and the energy storage component is electrically connected to the side of the control circuit board 62 facing the bottom wall 11. The energy storage component can be an energy storage capacitor or a storage battery such as an aluminum battery, a lithium iron phosphate battery, etc., and the energy storage component can be used as a transfer to provide a stable and reliable current and voltage for the lock 100.

[0057] Specifically, the locking beam 20 is a U-shaped structure, and the locking beam 20 includes a curved portion and a straight portion connected to both ends of the curved portion, with the direction parallel to the straight portion as the vertical direction, and the direction perpendicular to the straight portion as the horizontal direction, then the horizontal direction is the extension direction of the bottom wall 11, and the vertical direction is the extension direction of the side wall 12. In some embodiments, when the induced current induced by the NFC antenna 61 and the external mobile device reaches the requirement of the energy storage component, the energy storage component transfers the electric energy to the control circuit board 62, so that the control circuit board 62 controls the motor 40 to work, so that the motor 40 drives the conversion member 30 to move. It can be understood that the conversion member 30 can move along the extension direction of the bottom wall 11, and can also move along the extension direction of the side wall 12.

[0058] In some embodiments, the NFC antenna 61 and the mechanical lock core 50 are arranged along the extension direction of the bottom wall 11. Specifically, the NFC antenna 61 and the mechanical lock core 50 extend in the horizontal direction and are arranged at intervals. Since the NFC antenna 61 is an overall approximately rectangular structure, the NFC antenna 61 is extended along the bottom wall 11 to better adapt to the structure of the bottom wall 11, and the bottom wall 11 may be provided with a coil groove that cooperates with the coil.

[0059] In some embodiments, the control circuit board 62 is disposed between the mechanical lock cylinder 50 and the NFC antenna 61, and the control circuit board 62 is disposed along the extension direction of the bottom wall 11. Specifically, when the mechanical lock cylinder 50 is disposed in the horizontal direction, there is more space at the bottom to accommodate the NFC antenna 61 and the control circuit board 62 structure. The NFC antenna 61 and the control circuit board 62 are disposed in the horizontal direction, which can shorten the distance from the motor 40 structure and facilitate the power supply to the motor 40.

[0060] In some embodiments, the lock beam 20 includes an extension section 21 that can extend into the accommodating chamber 101, the motor 40 is placed between the extension section 21 and the mechanical lock core 50, and the motor 40 is arranged along the extension direction of the side wall 12. Specifically, the lock beam 20 is arranged close to the side wall 12, the motor 40 is arranged on the side of the lock beam 20 facing the mechanical lock core 50, and the motor 40 and the mechanical lock core 50 are respectively located on both sides of the conversion member 30. If the motor 40, the mechanical lock core 50, and the mechanical lock core 50 are all arranged in the horizontal direction, a larger space of the accommodating chamber 101 will be occupied, resulting in a larger size of the lock, affecting the appearance of the lock and the unlocking experience. When the motor 40 is arranged in the vertical direction, the mechanical lock core 50 is arranged in the horizontal direction, which can improve the spatial structure and ensure that the NFC antenna 61 does not protrude from the lock body.

[0062] The lock 100 further includes a steel ball 103, which is disposed between the conversion member 30 and the extension section 21. A lock body cavity 102 is further disposed in the accommodation chamber 101, and a steel ball groove for accommodating the steel ball 103 is disposed in the lock body cavity 102. When the conversion member 30 rotates to the first position, the notch 311 faces the extension section 21 and is disposed opposite to the hole 211, and the steel ball 103 can move toward the notch 311 and separate from the hole 211. At this time, the elastic potential energy of the spring is converted into kinetic energy, and the lock beam 20 bounces up under the action of the spring to complete the unlocking.

[0063] When the lock 100 is locked, the lock beam 20 is pressed down, the lock beam 20 releases the limit on the steel ball 103, the steel ball 103 moves toward the hole 211 and is partially located in the hole 211, and the upper roller 31 is reset and rotated to the second position. At this time, the notch 311 and the hole 211 are offset, and the steel ball 103 no longer enters the notch 311.
