Description

Technical Field

[0001] The utility model belongs to the field of intelligent door locks, and particularly relates to an intelligent door lock for waterproofing and preventing water vapor. Background Art

[0002] Most of the intelligent door locks used in the current market and industry have electronic components, but generally have a low waterproof level. At the same time, intelligent door locks usually have a hollow structure. If they are not waterproof, water vapor intrusion is likely to occur in areas with high humidity, resulting in short circuits of the electronic devices inside the intelligent door lock, which may damage the equipment or cause a fire risk. There is a need for waterproofing of intelligent door locks (including water and water vapor in the air), especially in scenarios such as outdoors and scenarios that require immersion in water (such as door locks in bathrooms or car door locks, etc.). When traditional door locks are applied to the above scenarios, internal component short circuits are likely to occur and they cannot work effectively. In addition, the overall size of existing intelligent door locks with waterproof functions is usually large, and it is not conducive to saving space. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problem that existing intelligent door locks do not have waterproof functions or have insufficient waterproof levels in the prior art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an intelligent door lock for waterproofing and preventing water vapor, including a lock body and a face cover. An installation cavity is provided inside the lock body, and a camera, a lock core, a sensor, and a main board assembly are installed in the installation cavity. The camera and the sensor are electrically connected to the main board assembly. The face cover is correspondingly provided with a keyhole, and the lock core is controlled to perform opening and closing actions through a corresponding key or the main board assembly. Waterproof parts are correspondingly provided for the camera, the lock core, and the sensor. A key cover is provided at the position corresponding to the keyhole on the face cover. Main board waterproof parts are provided before and after the main board assembly, and the door lock is waterproofed and protected against water vapor through the waterproof parts.

[0005] Preferably, the waterproof parts form a sealed structure with the corresponding camera, lock core, sensor, and main board assembly through interference fit.

[0006] Preferably, the waterproof parts are waterproof silica gels.

[0007] Preferably, the face cover and the lock body are connected by buckling or clamping.

[0008] Preferably, a waterproof groove is provided at the clamping position of the face cover and the lock body.

[0009] Preferably, the sensor is an infrared sensor, a bioelectric induction sensor, or an optical sensor.

[0010] Preferably, the side wall of the waterproof groove close to the inside of the lock body has an arc-shaped slope, and the other side wall of the waterproof groove is a vertical side wall.

[0011] The utility model has the following beneficial effects: in the lock body of the utility model, waterproof parts are arranged on the lock core, camera, special board component and sensor. By arranging waterproof parts on the key components of the utility model, especially the electronic parts, the waterproof level of the utility model is increased to ensure that water vapor in the air cannot invade the utility model, thus avoiding the risk of short circuit of the electronic devices in the intelligent door lock.

[0022] Embodiment

[0023] The following are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the following embodiments. Any technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model.

[0024] Refer to the attached Figure 1 , an intelligent door lock for preventing water and water vapor, comprising a lock body 8 and an intelligent lock face cover 1. An installation cavity is provided in the lock body 8. A camera 2, a lock core, a human body sensor 6 and a main board assembly 10 are installed in the installation cavity. The camera 2 and the human body sensor 6 are electrically connected to the main board assembly 10. A keyhole is provided on the face cover corresponding to the position of the lock core. The lock core is controlled to perform opening and closing actions through a corresponding key or the main board assembly 10. Specifically, the main board assembly 10 judges whether someone is approaching the intelligent door lock through the human body sensor 6. When it is judged that someone is approaching, the camera is used to collect a portrait and compare it with the stored portrait to judge whether it is a stored portrait. When it is judged to be the case, the main board assembly 10 controls the lock core to open the door. Similarly, the lock core can also perform the opening action mechanically. The human body sensor 6 can be an infrared sensor, a bioelectric induction sensor or an optical sensor.

[0025] The camera 2, the lock core and the human body sensor 6 are respectively provided with waterproof parts, and the waterproof parts are waterproof silica gels. The reason for choosing waterproof silica gel as the waterproof part is that first, the waterproof effect of waterproof silica gel is good. At the same time, waterproof silica gel is relatively light and occupies a small area, and can be flexibly molded according to the parts to be waterproofed, especially the key parts to be waterproofed. In particular, there are small gaps in the circuit board, and the waterproof silica gel can also be engaged with the corresponding protrusions to achieve a good waterproof effect.

[0026] A key cover 3 is provided at the position corresponding to the keyhole on the face cover, and a keyhole waterproof silica gel 4 is provided correspondingly to prevent water ingress in front of the lock core. At the same time, a lock core waterproof silica gel 7 is also provided at the rear of the lock core to ensure that the lock core can achieve a high waterproof level both mechanically and electronically. Waterproof silica gels 9 are provided both in front of and behind the main board assembly 10, and the above-mentioned waterproof silica gels are used to waterproof the door lock.

[0027] Refer to the attached instruction manual Figure 2-3 , the smart lock face cover 1 and the lock body 8 are connected by buckling or clamping. A waterproof groove 81 is provided at the clamping position between the smart lock face cover 1 and the lock body. Refer to the attached instruction manual Figure 3 , the waterproof groove 81 is a groove formed at the buckling position between the smart lock face cover 1 and the lock body 8. The groove is provided near the outside of the lock body. The purpose is to allow the water vapor outside the lock body to enter the groove first when entering the lock body. Refer to the attached instruction manual Figure 3 , the side wall near the outside of the groove is a vertical side wall 82, and the purpose is to directly let the water vapor flow into the groove. Since the lock body is vertically arranged, the groove can not only block the invasion of water vapor but also play a guiding role. The other side wall of the groove has an arc-shaped slope 83, which is to prevent the water vapor in the groove from easily invading the inside of the lock body through the clamping position between the smart lock face cover 1 and the lock body 8.

[0028] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
