[0031] Embodiment 1:

[0032] See also Figure 1-Figure 6 This embodiment provides a door access control installation structure, including a door access control device. The door access control device includes a housing 1, a controller 2, an alarm 3 and a vibration sensor 4, and the housing 1 is fixed on a base surface.

[0033] The controller 2 includes a PCB board 21 and a main control chip 22, and the main control chip 22 is mounted on the PCB board 21 to be electrically connected to the PCB board 21. The controller 2 also includes some hardware modules for performing access control functions, which are also mounted on the PCB board 21 and electrically connected to the main control chip 22. In this embodiment, the PCB board 21 is mounted in the housing 1, so the main control chip 22 and the hardware modules for performing access control functions are also located in the housing 1.

[0034] The alarm 3 is electrically connected to the main control chip 22, and the alarm 3 sounds an alarm based on the signal sent by the main control chip 22 to alert people around the access control device. In some embodiments, the alarm 3 can be a flash alarm. In this case, in order for the alarm 3 to have an alarm effect, the alarm 3 needs to be set outside the housing 1, or a light-transmitting hole needs to be set on the housing 1, so that when the alarm 3 sounds an alarm, light is irradiated to the outside of the housing 1, which plays a role in alerting people around the access control device. In this embodiment, the alarm 3 is a buzzer, so the alarm 3 can have an alarm effect even inside the housing 1. In some other embodiments, the alarm 3 can also be an audible and visual alarm.

[0035] Based on the characteristic that the alarm 3 of this embodiment is a buzzer, the alarm 3 does not need to be set on the outside of the casing 1. The alarm 3 can be directly installed on the PCB board 21 and electrically connected to the main control chip 22 through the PCB board 21, thereby reducing the use of wires between the alarm 3 and the main control chip 22. The alarm 3 is set inside the casing 1 together with the PCB board 21 without affecting the normal alarm of the alarm 3, and can be protected by the casing 1.

[0036] The alarm principle of the access control device in this embodiment is: when the access control device is violently dismantled, since the vibration sensor 4 is installed on the casing 1, the casing 1 will drive the vibration sensor 4 to shake more violently, and the vibration sensor 4 will generate a corresponding electrical signal. Further, since the vibration sensor 4 is electrically connected to the main control chip 22, the vibration sensor 4 can send the generated electrical signal to the main control chip 22. The main control chip 22 controls the alarm 3 to sound an alarm based on the received electrical signal, thereby reminding the surrounding people that the access control device is being violently dismantled.

[0037] Based on the above alarm principle, as long as the casing 1 can transmit the vibration to the vibration sensor 4 when vibrating, the connection relationship between the vibration sensor 4 and the casing 1 is not limited. The vibration sensor 4 can be directly installed on the side wall of the casing 1 or indirectly installed on the side wall of the casing 1.

[0038] In this embodiment, the vibration sensor 4 is preferably installed on the PCB board 21. On the one hand, the housing 1 can transmit the vibration to the vibration sensor 4 through the PCB board 21. On the other hand, the vibration sensor 4 can be electrically connected to the main control chip 22 through the PCB board 21, reducing the use of wires.

[0039] In this embodiment, the base surface where the housing 1 is located is a wall surface. In order to fix the housing 1 on the wall surface, the access control device generally further includes a base surface mounting bracket 5. The base surface mounting bracket 5 is fixed to the outer wall surface of the housing 1, and the housing 1 is mounted on the wall surface through the base surface mounting bracket 5.

[0040] Accordingly, when the access control device is violently disassembled, the base surface mounting bracket 5 and the housing 1 may be forced to separate. Based on this, the access control device of this embodiment also includes a first anti-disassembly switch 6. When the housing 1 is mounted on the base surface mounting bracket 5, the first anti-disassembly switch 6 will be squeezed by the base surface mounting bracket 5, and will move or deform. At this time, the two ends of the first anti-disassembly switch 6 are respectively abutted on the base surface mounting bracket 5 and the PCB board 21, thereby making the first anti-disassembly switch 6 electrically connected to the main control chip 22, and the corresponding detection circuit between the first anti-disassembly switch 6 and the main control chip 22 is turned on. Once the housing 1 is separated from the base surface mounting bracket 5 due to violent disassembly, the first anti-disassembly switch 6 will reset or recover by itself when it loses the squeezing of the base surface mounting bracket 5, thereby disconnecting the detection circuit between the first anti-disassembly switch 6 and the main control chip 22, and the main control chip 22 controls the alarm 3 to sound an alarm based on the disconnection signal.

[0041] The access control device is generally connected to an external power supply to continuously supply power to the main control chip 22. When the access control device is violently disassembled, if the access control device and the external power supply have not been disconnected, the alarm 3 can continue to sound the alarm. If the access control device and the external power supply are disconnected, the alarm 3 may stop the alarm in advance before the surrounding people notice the violent disassembly. In order to enable the access control device to continue to sound the alarm after being disconnected from the external power supply, the access control device in this embodiment also includes a battery 9, which is installed in the housing 1 and electrically connected to the PCB board 21. After the access control device is disconnected from the external power supply, the battery 9 can continue to supply power to the main control chip 22 and the alarm 3 through the PCB board 21. Further preferably, the battery 9 can be directly installed on the PCB board 21, thereby reducing the layout of the wires.

[0042] Preferably, the access control device also includes a switching power supply 10, which is installed on a PCB board 21. The switching power supply 10 is electrically connected between an external power supply and the PCB board 21. When the external power supply and the access control device are connected, the main control chip 22 and the alarm 3 need to be powered via the main control chip 22.

[0043] In this embodiment, the housing 1 includes a base 11, a second cover plate 13 and a first cover plate 12. The second cover plate 13 and the first cover plate 12 are both detachably mounted on the base 11, and the first cover plate 12 and the second cover plate 13 are both connected to the base 11 by snaps. The first cover plate 12 and a part of the base 11 are surrounded to form a wiring cavity 121, and the second cover plate 13 and a part of the base 11 are surrounded to form an installation cavity 131. The controller 2, the switching power supply 10 and the alarm 3 are all located in the installation cavity 131, and the wiring cavity 121 is used for wiring. The PCB board 21 is fixed on the side wall of the installation cavity 131 to ensure that the vibration of the base 11 can be effectively transmitted to the PCB board 21, and then detected by the vibration sensor 4 on the PCB board 21.

[0044] Therefore, some violent disassembly of the access control device may occur between the second cover plate 13 and the base 11, or between the first cover plate 12 and the base 11. Therefore, the access control device of this embodiment further includes a second anti-disassembly switch 7 and a third anti-disassembly switch 8, and the second anti-disassembly switch 7 and the third anti-disassembly switch 8 are both electrically connected to the main control chip 22.

[0045] Taking the second anti-disassembly switch 7 as an example, when the first cover plate 12 is not separated from the base 11, the second anti-disassembly switch 7 is squeezed by the first cover plate 12 to move or deform, and the two ends of the second anti-disassembly switch 7 are respectively abutted on the PCB board 21 and the first cover plate 12, thereby realizing the electrical connection between the second anti-disassembly switch 7 and the main control chip 22, and the corresponding detection circuit between the second anti-disassembly switch 7 and the main control chip 22 is connected. When the first cover plate 12 is violently removed, the second anti-disassembly switch 7 is reset or restored, thereby disconnecting the detection circuit between the second anti-disassembly switch 7 and the main control chip 22, and the main control chip 22 controls the alarm 3 to sound an alarm based on the signal.

[0046] Similarly, when the second cover plate 13 is not separated from the base 11, the third anti-disassembly switch 8 is squeezed by the second cover plate 13 to move or deform, and the two ends of the third anti-disassembly switch 8 are respectively abutted on the PCB board 21 and the second cover plate 13, thereby realizing the electrical connection between the third anti-disassembly switch 8 and the main control chip 22, and the corresponding detection circuit between the third anti-disassembly switch 8 and the main control chip 22 is connected. When the second cover plate 13 is violently removed, the third anti-disassembly switch 8 is reset or restored, thereby disconnecting the detection circuit between the third anti-disassembly switch 8 and the main control chip 22, and the main control chip 22 controls the alarm 3 to sound an alarm based on the signal.

[0047] In addition, as long as any one of the vibration sensor 4, the first anti-disassembly switch 6, the second anti-disassembly switch 7 and the third anti-disassembly switch 8 triggers the alarm 3 through the main control chip 22, the main control chip 22 can also notify the monitoring personnel in the remote control room through a wired or wireless signal, so as to deal with the situation where there is no management personnel around the access control device when violent disassembly occurs. The working principles and structures of the vibration sensor 4, the first anti-disassembly switch 6, the second anti-disassembly switch 7 and the third anti-disassembly switch 8 are all prior arts, and will not be described in detail in this embodiment.

[0048] If the access control device needs to be disassembled and repaired normally, as long as the maintenance personnel pass the authentication of the access control device normally, the main control chip 22 can control the alarm 3 not to sound an alarm during the maintenance process.

[0049] A partition 14 is provided between the wiring cavity 121 and the installation cavity 131, and a clearance opening is provided on the partition 14. The controller 2 and the switching power supply 10 can be connected to the line of the wiring cavity 121 through the clearance opening. A plurality of wiring holes 1211 are provided on the side wall of the wiring cavity 121 of the base 11.

[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
