FIG.2is a diagram showing a rear side of the electric lock of the present invention.FIG.3is a diagram showing the rear side of the electric lock of the present invention from another viewing angle.FIG.4is an exploded view of the electric lock of the present invention. As shown in figures, the electric lock10of the present invention comprises a housing20, a driving module30, a motor40and a control circuit50. The housing20comprises a first casing100and a second casing200. The first casing100has a main body102, a first side wall110, a second side wall120, a third side wall130and a fourth side wall140. The first to fourth side walls110,120,130,140are extended from the main body102along a height direction D1of the first casing100. The first side wall110and the second side wall120are arranged at opposite sides of the first casing100, and the third side wall130and the fourth side wall140are arranged at opposite sides of the first casing100. The second casing200is mounted between the first side wall110and the second side wall120, and mounted between the third side wall130and the fourth side wall140. In other words, the second casing200is mounted in a space surrounded by the first to fourth side walls110,120,130,140. When the first casing100and the second casing200are combined, an accommodating space is formed between the first casing100and the second casing200for accommodating components of the electric lock10, such as the driving module30, the motor40and the control circuit50.

The driving module30is configured to drive a predetermined mechanism in the electric lock10to move to perform a predetermined operation. For example, the predetermined mechanism can be a latch mechanism of the electric lock10, and the driving module30is configured to drive the latch mechanism to move to perform a locking operation or an unlocking operation; or the predetermined mechanism can be a clutch mechanism of the electric lock10, and the driving module30is configured to drive the clutch mechanism to move to perform a locking operation or an unlocking operation, but the present invention is not limited thereto. The motor40is connected to the driving module30. When the motor40rotates, the motor40is configured to drive the driving module30to perform the aforementioned operations. The control circuit50is configured to control rotation of the motor according to control parameters of the motor40in order to further drive the driving module30to drive the predetermined mechanism to move.

In addition, the second casing200is formed with at least one first buckle structure210adjacent to the first side wall110. In the present embodiment, the second casing200is formed with two first buckle structures210adjacent to the first side wall110, but the present invention is not limited thereto. The first buckle structure210comprises a first elastic arm212extended along the height direction D1of the second casing200, and a first protrusion214protruded from the first elastic arm212and extended toward the first side wall110. The first side wall110is formed with a first blocking part112configured to abut against the first protrusion214when the first casing100and the second casing200are combined in order to prevent the second casing200from moving away from the first casing100along the height direction D1. In the present embodiment, the first blocking part112is protruded from the first side wall110, but the present invention is not limited thereto. In addition, an upper end of the first blocking part112is formed with a first upper inclined surface114.

The second casing200is further formed with at least one second buckle structure220adjacent to the second side wall120. In the present embodiment, the second casing200is formed with two second buckle structures220adjacent to the second side wall120, but the present invention is not limited thereto. Similarly, the second buckle structure220comprises a second elastic arm222extended along the height direction D1of the second casing200, and a second protrusion224protruded from the second elastic arm22and extended toward the second side wall120. The second side wall120is formed with a second blocking part122configured to abut against the second protrusion224when the first casing100and the second casing200are combined in order to prevent the second casing200from moving away from the first casing100along the height direction D1. In the present embodiment, the second blocking part122is protruded from the second side wall120, but the present invention is not limited thereto. In addition, an upper end of the second blocking part122is formed with a second upper inclined surface124.

Please refer toFIG.5, andFIG.1toFIG.4as well.FIG.5is a diagram showing the second casing of the electric lock of the present invention. As shown in figures, the second casing200is further formed with at least one first rebound structure230adjacent to the first buckle structure210, and at least one second rebound structure240adjacent to the second buckle structure220. In the present embodiment, the second casing200is formed with one first rebound structure230adjacent to the first buckle structure210, and two second rebound structures240adjacent to the second buckle structure220, but the present invention is not limited thereto. In addition, the first rebound structure230comprises a first cantilever232and a first protrusion part234protruded from the first cantilever232; the second rebound structure240comprises a second cantilever242and a second protrusion part244protruded from the second cantilever242. In the present embodiment, the first buckle structure210, the second buckle structure220, the first rebound structure230, and the second rebound structure240are integrally formed on the second casing200. For example, the second casing200is formed by plastic injection molding.

Please refer toFIG.6andFIG.7, andFIG.1toFIG.5as well.FIG.6is a diagram showing assembly of the housing of the electric lock of the present invention.FIG.7is a diagram showing disassembly of the housing of the electric lock of the present invention. When the first casing100and the second casing200are combined, the first protrusion part234of the first rebound structure230is configured to abut against the first casing100such that the first cantilever232is elastically deformed to accumulate an elastic force, and the second protrusion part244of the second rebound structure240is configured to abut against the motor40such that the second cantilever242is elastically deformed to accumulate an elastic force (as shown inFIG.6). When the first side wall110and the second side wall120are pulled outward along a lateral direction D2of the first casing100, the first blocking part112no longer abuts against the first protrusion214, and the second blocking part122no longer abuts against the second protrusion224. Meanwhile, the first rebound structure230and the second rebound structure240are configured to provide the elastic forces along the height direction D1to push the second casing200away from the first casing100along the height direction D1(as shown inFIG.7).

According to the aforementioned arrangement, during a process of dissembling the housing20, a user only needs to pull the first side wall110and the second side wall120outward along the lateral direction D2of the first casing100, such that the second casing200can be automatically detached from the first casing100along the height direction D1. Therefore, the housing20of the electric lock of the present invention is easier to disassemble, and the first buckle structure210and the second buckle structure220are not easily broken or damaged during the disassembly process.

On the other hand, a lower end of the first protrusion214is formed with a first lower inclined surface216corresponding to the first upper inclined surface114, and a lower end of the second protrusion224is formed with a second lower inclined surface226corresponding to the second upper inclined surface124. Therefore, during an assembly process of the housing, the user only needs to press down the second casing200toward the first casing100along the height direction D1, such that the first protrusion214and the second protrusion224can easily cross the first blocking part112and the second blocking part122respectively through interaction between the first upper inclined surface114and the first lower inclined surface216and between the second upper inclined surface124and the second lower inclined surface226(and through elastic deformation of the first elastic arm212and the second elastic arm222), so as to combine the first casing100and the second casing200.

Moreover, when the first casing100and the second cover200are combined, the second rebound structure240is configured to abut against the motor40. Therefore, the second rebound structure240can reduce vibration of the motor40during operation, so as to prevent a welding point between the motor40and a power cable from being damaged due to the vibration. In the present embodiment, the second rebound structures240are arranged along a longitudinal direction of the motor to respectively abut against two opposite ends of the motor40, so as to improve vibration absorption effect.

In contrast to the prior art, the housing20of the electric lock10of the present invention can be easily dissembled and assembled, and the first buckle structure210and the second buckle structure220are not easily broken or damaged during the disassembly process. In addition, the second rebound structure240on the second casing200can abut against the motor40to reduce the vibration of the motor40during operation, thereby increasing stability and reliability of the electric lock10of the present invention.
