Description

Technical Field

[0001] This utility model relates to an intelligent door lock with anti-tamper alarm function. Background Technology

[0002] Currently, smart door locks on the market offer multiple unlocking methods, including fingerprint unlocking, password unlocking, facial recognition unlocking, and mechanical key unlocking, thus meeting all user unlocking needs and gaining popularity. Smart door locks also feature alarm systems that sound an alarm when the lock is tampered with, alerting the user and neighbors and deterring thieves. Conventional anti-tampering functions typically use infrared sensors; a change in the sensing distance indicates tampering. However, infrared sensors are relatively cumbersome to install on the door and adjust the infrared distance.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned problems and provide a smart door lock with an anti-tamper alarm function. The anti-tamper alarm function adopted by this smart door lock has the advantage of easy installation.

[0005] To achieve the above objectives, this utility model provides an intelligent door lock with an anti-tamper alarm function, comprising a housing and a control circuit board mounted on the housing. A conductive spring body is located on one side of the back of the housing. The control circuit board has an alarm module, which has an inner conductive part and an outer conductive part surrounding the inner conductive part. The conductive spring body includes an outer spring and an inner spring connected together, with the inner spring located inside the outer spring. The length of the outer spring is greater than the length of the inner spring. The outer spring corresponds to the outer conductive part, and the inner spring corresponds to the inner conductive part. When the housing is assembled onto the door, the outer spring and inner spring are compressed and respectively connect to the outer and inner conductive parts. When the housing is pried open, the outer spring recovers its deformation and disconnects the inner spring from the inner conductive part, thereby triggering the alarm module.

[0006] In one or more embodiments, the control circuit board is provided with a positioning enclosure around the outer conductive portion, and at least a portion of the outer spring extends into the positioning enclosure.

[0007] In one or more embodiments, the alarm module is a sound alarm.

[0008] In one or more embodiments, the control circuit board is provided with a wireless communication module, which can establish network communication with Wi-Fi. When the alarm module is triggered, the wireless communication module sends alarm information to the user's mobile device.

[0009] In one or more embodiments, the control circuit board is provided with a SIM card slot.

[0010] In one or more embodiments, a decorative cover is provided on the front side of the housing, and the decorative panel is fastened to the housing.

[0011] Compared with the prior art, the advantages of this utility model are: after the housing is installed, the circuit is connected through the spring body, and when the housing is pried open, the alarm module is triggered by the spring restoring its deformation. The smart door lock with this structure does not need to be adjusted in distance during installation; the housing can be fixed directly with screws, which is very convenient.

[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0015] Please refer to the appendix. Figure 1-2 This application provides a smart door lock with an anti-tamper alarm function, which includes a housing 1 and a control circuit board 2 mounted on the housing. The control circuit board has a conductive spring body on one side of the back of the housing 1. The control circuit board 2 has an alarm module. The alarm module has an inner conductive part and an outer conductive part surrounding the inner conductive part. The conductive spring body includes an outer spring 3 and an inner spring 4 connected together. The inner spring 4 is located inside the outer spring 3, and the length of the outer spring 3 is greater than the length of the inner spring 4. The outer spring 3 corresponds to the outer conductive part, and the inner spring 4 corresponds to the inner conductive part. When the housing 1 is assembled into the door, the outer spring 3 and the inner spring 4 are compressed and connected to the outer conductive part and the inner conductive part respectively, i.e., a closed circuit. When the housing 1 is pried open, the outer spring 3 recovers its deformation and disconnects the inner spring 4 from the inner conductive part, thereby triggering the alarm module. Specifically, when the housing is pried open, both the outer spring and the inner spring lose the support of the door and therefore deform. Since the length of the outer spring is greater than that of the inner spring, the process of the outer spring recovering its deformation is also the process of the inner spring gradually recovering its deformation, and the inner spring disconnects from the inner conductive part.

[0016] The control circuit board 2 is provided with a positioning wall 5 around the outer conductive part. At least a portion of the outer spring 3 extends into the positioning wall 5. The positioning wall is used to install the outer spring to ensure that the outer spring is not easily detached when the housing is assembled into the door.

[0017] The alarm module is a sound alarm, which is more direct and can emit an alarm sound to remind users and nearby neighbors, thus more directly scaring away thieves.

[0018] The control circuit board 2 is equipped with a wireless communication module, which can establish network communication with Wi-Fi. When the alarm module is triggered, the wireless communication module sends alarm information to the user's mobile device, which can be a smartphone. The user can receive the alarm information from the alarm module through an app on the smartphone. When the smart lock is installed in an environment without Wi-Fi, the control circuit board 2 is equipped with a SIM card slot for convenient communication. After inserting a SIM card, communication can be achieved using the SIM card's data plan.

[0019] A decorative cover 6 is provided on the front of the housing 1, and the decorative panel is fastened to the housing. This allows for easy removal of the decorative cover, so that when the smart lock is out of power, the door lock can be opened with a mechanical key by removing the decorative cover.

[0020] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
