[0026] It should be noted that the control chip 5 can be installed in the lock housing 1 . Figure 2 The lock housing 1 is shown in an open state, so as to facilitate observation of the components installed inside the lock housing 1 . In actual implementation, the lock housing 1 has a closing panel (not shown in the figure), which is used to completely close the lock housing 1 .

[0027] In an exemplary embodiment, the first mounting plate 3 includes a first assembly plate 31, a first transverse support plate 32 and a first vertical support plate 33, the first assembly plate 31 is fixed to the outer side of the lock housing 1, the first transverse support plate 32 is fixedly connected to the first assembly plate 31, the first vertical support plate 33 is fixedly connected to the first transverse support plate 32, and one end of the rotating shaft 7 is rotatably disposed on the first vertical support plate 32.

[0028] In an exemplary embodiment, the second mounting plate 4 includes a second vertical support plate 41, a second horizontal support plate 42, a third vertical support plate 43 and a fourth horizontal support plate 44, the second vertical support plate 41 is fixedly connected to the first assembly plate 31, the second horizontal support plate 42 is fixedly connected to the second vertical support plate 41, and the second horizontal support plate 42 is fixedly connected to the fourth horizontal support plate 44 via the third vertical support plate 43.

[0029] In an exemplary embodiment, the scanning assembly 9 is disposed on the second cross brace plate 42 .

[0030] In an exemplary embodiment, a switch button 11 is disposed on the third vertical support plate 43 , and the switch button 11 is electrically connected to the scanning component 9 to control the opening and closing of the scanning component 9 .

[0031] In an exemplary embodiment, a return torsion spring 12 is disposed on the rotating shaft 7 .

[0032] In an exemplary embodiment, a motor mounting seat 13 is disposed in the lock housing 1 , and the motor 6 is fixed on the motor mounting seat 13 .

[0033] The inductive passive lock cylinder needs a corresponding smart key to open. The embodiment of the utility model provides a smart key, which is used to open the inductive passive lock cylinder as described above. Figure 4 As shown, the smart key includes a key body 14 , on which a unique identifier 10 is provided. The key body 14 is used to open the rotary lock cylinder 2 , and the unique identifier 10 can be identified by the scanning component 9 .

[0034] The opening process of the inductive passive lock cylinder is described in detail in conjunction with the smart key. The key body 14 matching the rotary lock cylinder 2 is inserted into the rotary lock cylinder 2 and contacts the switch button 11, so that the switch button 11 is activated, thereby opening the scanning component 9. As the key body 14 rotates, the unique identifier 10 can be scanned and identified by the scanning component 9. The control chip 5 controls the motor 6 to work for a certain period of time according to the scanning and identification results of the scanning component 9. If the identified unique identifier 10 is exactly the preset unlocking condition, the control chip 5 controls the motor 6 to work for a certain period of time, and the rotation of the shaft 7 causes the lock tongue 8 to rotate, so that the inductive passive lock cylinder is opened. After the motor 6 stops working, the shaft 7 returns to its position under the action of the reset torsion spring 12, and the lock tongue 8 returns to its position. After taking out the key body 14, since the switch button 11 is a spring-loaded button, the switch button 11 is reset and the scanning component 9 is turned off, so that the scanning component 9 only works after the switch button 11 is turned on. The control chip 5 is in a dormant state when there is no need to unlock the lock, and only starts to enter the working state after receiving the signal fed by the scanning component 9. Therefore, the power consumption of the overall electronic components is relatively low, and the electronic components can be powered by batteries, which can be installed in the lock shell 1.

[0035] Exemplarily, the scanning component 9 may be a radio frequency scanner, and the unique identifier 10 may be a unique identification code that can be scanned by the radio frequency scanner.

[0036] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
