The shielding cover body 1 is to be movably installed onto a lock panel of a smart door lock. The attraction member 2 is installed on a side of the shielding cover body 1 adjacent to the lock panel of the smart door lock, and is configured to attach the shielding cover body 1 to the lock panel of the smart door lock by attraction. Multiple through holes 3 are defined in the attraction member 2. The blocking portions 4 correspond to the through holes 3 in a one-to-one manner. Each blocking portion 4 is fixed to the shielding cover body 1 through a connecting portion 5 that penetrates the through hole 3, thereby fixing the attraction member 2 to the shielding cover body 1.
The above-described door lock shielding cover includes the shielding cover body 1, the attraction member 2 installed on the shielding cover body 1, the connecting portions 5, and the blocking portions 4. The connecting portions 5 and the blocking portions 4 are configured to connect the shielding cover body 1 with the attraction member 2. The shielding cover body 1 is to be movably installed onto the lock panel of the smart door lock. The shielding cover body 1 in a shielding position covers the emergency keyhole of the smart door lock. When the shielding cover body 1 is in other positions, the emergency keyhole is exposed for unlocking the smart door lock by using an emergency key. The shielding cover body 1 is secured to the lock panel of the smart door lock by the attraction member 2. When the attraction member 2 is attracted to the lock panel of the smart door lock, the shielding cover body 1 is located in the shielding position. When the attraction member 2 is not attracted to the lock panel of the smart door lock, the shielding cover body 1 is located in other positions. The shielding cover body 1 and the attraction member 2 are fixed by the connecting portions 5 and the blocking portions 4. The multiple through holes 3 are defined in the attraction member 2. The blocking portions 4 corresponding to the through holes 3 in the one-to-one manner are disposed on the side of the attraction member 2 away from the shielding cover body 1. Each blocking portion 4 is fixed to the shielding cover through the connecting portion 5 penetrating through the through hole 3. The connecting portion 5 is located on the surface of the shielding cover body 1 at the side facing the lock panel of the smart door lock. In the process of installing the attraction member 2, the through holes 3 of the attraction member 2 are positioned corresponding to the connecting portions 5, and the connecting portions 5 passing through the through holes 3 are connected to the blocking portions 4, thereby limiting the position of the attraction member 2 between the shielding cover body 1 and the multiple blocking portions 4 in order to achieve a fixed connection between the attraction member 2 and the shielding cover body 1. The above-described door lock shielding cover adopts the connecting portions 5 and the blocking portions 4 to limit the position of the attraction member 2 between the shielding cover body 1 and the blocking portions 4. This fixing manner is firmer compared with the glue bonding method that is not secure and endurable due to material difference between the cover body 1 and the attraction member 2. This fixing manner between the shielding cover body 1 and the attraction member 2 in the door lock shielding cover is not restricted by the materials thereof, and the firmness of the fixation between the shielding cover body 1 and the attraction member 2 can be ensured.
The attraction member 2 can be made of iron. A magnet can be arranged in the lock panel of the smart door lock at the region around the emergency keyhole. The attraction member 2 is secured to the magnet through the magnetic attraction. When the attraction member 2 is attracted to the magnet, the shielding cover body 1 is located at the shielding position to shield the emergency keyhole.

In an embodiment, in the above-described door lock shielding cover, the shielding cover body 1 is made of the plastic material, and the shielding cover body 1, the connecting portion 5, and the blocking portion 4 are integrated together as one piece. During the manufacturing process, the shielding cover body 1 is integrated formed with the connecting portion 5 as one piece. In installation of the attraction member 2 onto the shielding cover body 1, each connecting portion 5 passes through one through hole 3 corresponding to the connecting portion 5. The length of the connecting portion 5 is greater than the thickness of the attraction member 2. Then the end of the connecting portion 5 away from the shielding cover body 1 is thermally melted to form the blocking portion 4 on the side of the attraction member 2 away from the shielding cover body 1. The length of the connecting portion 5 can be designed according to actual needs.
In an embodiment, as shown in
The through holes 3 in the attraction member 2 are counterbores, so that the blocking portions 4, formed from the thermal melting process of the ends, away from the shielding cover body 1, of the connecting portions 5, are located in the counterbores; the blocking portions 4 are flush with the surface of the attraction member 2, thus avoiding abrasion of a protruding blocking portion 4, increasing the firmness of the fixation, and ensuring the smoothness of the appearance as well.
