In order to solve the above technical problems, as shown in fig. 1 to 8, an embodiment of the present utility model provides a waterproof structure for a doorbell, which includes: the device comprises a shell 1, a silica gel key 6 and a PCB 11; wherein,,

the inner side of the shell 1 is provided with a first protruding surrounding rib 2, and the first surrounding rib 2 surrounds the periphery of a waterproof area on the shell 1;

the silica gel key 6 is arranged on the inner side of the shell 1 and props against the first surrounding bone 2;

the PCB 11 is attached to the silica gel key 6 and fixedly connected with the shell 1.

In this embodiment, as shown in fig. 4 and 5, the housing 1 is a front shell structure of a video doorbell, which may be a plastic piece. The inner side of the shell 1 is provided with a mounting plane, a first protruding surrounding rib 2 is formed on the mounting plane, and the first surrounding rib 2 is arranged along a waterproof area on the shell 1 and surrounds the waterproof area. The waterproof area on the casing 1 refers to the periphery of each functional area on the casing 1, and the functional areas can be a key area, a nameplate area or a screen display area, etc. The silica gel key 6 is installed at the inner side of the housing 1, and the silica gel key 6 has a function part corresponding to each function area. In order to waterproof each functional part, in this embodiment, a protruding first surrounding rib 2 is formed on the inner side of the housing 1, after the silica gel key 6 is assembled on the inner side of the housing 1, the surface of the silica gel key 6 is propped against the first surrounding rib 2, so that the area surrounded by the first surrounding rib 2 becomes a closed area, and water located on the outer side of the first surrounding rib 2 cannot enter the closed area, thereby realizing the waterproof of each functional part on the silica gel key 6. The back at silica gel button 6 is installed to PCB board 11, and PCB board 11 is after the installation with casing 1 fixed connection and apply certain pressure with silica gel button 6 to make silica gel button 6 can more closely paste on first surrounding bone 2.

The first surrounding bone 2 can be integrally formed with the shell 1, and the shell 1 with the first surrounding bone 2 can be directly formed in a mold injection molding process. The material of the first surrounding bone 2 and the material of the shell 1 can be kept consistent, so that the production is simpler, a double-color mold is not required to be used due to water resistance, and the production cost is lower.

The purpose that the first convex surrounding rib 2 and the silica gel key 6 are propped against each other to form a waterproof structure surrounding a waterproof area is achieved, so that the technical effect of improving the waterproof performance of the visual doorbell through a simpler structure is achieved, and the problem that the waterproof performance of the visual doorbell is poor in the related art is solved.

As shown in fig. 4 and 5, in order to facilitate the fixed connection between the PCB 11 and the housing 1, a plurality of connection studs 5 are provided on the inner side of the housing 1, connection holes 10 are provided on the PCB 11, through holes corresponding to the connection studs 5 are also provided on the silica gel keys 6, and after the silica gel keys 6 are installed, the through holes are sleeved on the corresponding connection studs 5. A screw is arranged in the connecting hole 10 and is in threaded connection with the connecting stud 5. Since the screws pass through the connection holes 10 on the PCB 11 and the connection studs 5 on the housing 1 for connection, the connection studs 5 also need to be waterproof as a waterproof area, i.e. the first surrounding rib 2 in this embodiment also needs to be disposed around the connection studs. When the screw is installed, the torque force is less than or equal to 1.6kgf.cm, so that the connecting stud 5 is prevented from slipping.

In order to facilitate pressing the key, in this embodiment, a key hole 3 is formed in the housing 1, a key portion 8 protruding toward the housing 1 is provided on the silica gel, after the silica gel key 6 is installed, the key portion 8 is embedded in the key hole 3, and the waterproof area includes the periphery of the key hole 3. Since the silica gel key 6 is of a flexible structure, the edge of the key part 8 can be brought into close contact with the key hole 3 after installation. Further, the number of the key holes 3 is plural, and the waterproof area includes the periphery of each key hole 3. In this embodiment, the number of the key holes 3 is four, and the periphery of each key hole 3 is provided with a first surrounding bone 2, and the first surrounding bones 2 of each part form a whole.

According to the requirements, the shell 1 is also provided with a nameplate hole 4, the waterproof area comprises the periphery of the nameplate hole 4, the corresponding silica gel key 6 is also provided with a nameplate part 7, and the nameplate part 7 is embedded in the nameplate hole 4; in order to facilitate checking nameplates and keys when outdoor environment is dim, the silica gel keys 6 in the embodiment are made of light-permeable silica gel, lamps and patch keys can be distributed on the PCB 11, under the premise of realizing water resistance, the hand feeling of the keys is improved through silica gel light transmission,

in order to enable the PCB 11 to be stably mounted on the housing 1, the connecting studs 5 in this embodiment are disposed in a plurality of positions around the key hole 3 and the nameplate hole 4, and the corresponding connecting holes 10 on the PCB 11 are also disposed in a plurality of positions. In order to make the elastic deformation of the structure react on the silica gel key 6 as much as possible instead of the PCB 11 and the shell 1 during installation, the connecting studs 5 around the key hole 3 in this embodiment are uniformly distributed, and the connecting studs 5 around the nameplate hole 4 are uniformly distributed. Corresponding to the present embodiment, the connection studs 5 in the length direction and the width direction of the housing 1 are uniformly distributed.

In order to obtain better elastic force feedback when the key part 8 of the silica gel key 6 is pressed, the pressure transmitted to the PCB 11 by the silica gel key 6 needs to be more concentrated. As shown in fig. 6 to 8, in this embodiment, a protruding second surrounding rib 9 is disposed on one side of the silica gel key 6 close to the PCB board 11, the second surrounding rib 9 corresponds to the first surrounding rib 2, and the PCB board 11 is pressed and attached to the second surrounding rib 9. The contact area between the silica gel key 6 and the PCB 11 is reduced through the setting of the second surrounding rib 9, so that the local pressure born by the silica gel key 6 during pressing is improved, and better pressing hand feeling can be obtained during pressing. Meanwhile, the structural strength of the silica gel key 6 can be enhanced by the arrangement of the second surrounding rib 9, and the durability of the silica gel key 6 can be improved.

In this embodiment, the trend of the second surrounding bone 9 and the trend of the first surrounding bone 2 may be completely identical or may be partially identical. In the case of partial agreement, the difference is that there is a first surrounding rib 2 between adjacent key holes 3, but no second surrounding rib 9 is provided between adjacent key portions 8.

Furthermore, in order to reduce the cost, the second surrounding rib 9 and the silica gel key 6 are made of the same material, and can be integrally formed. On this basis, because the second surrounding rib 9 is of a flexible structure, and the PCB 11 can squeeze the second surrounding rib 9 during installation, in order to avoid the second surrounding rib 9 from generating overlarge dislocation relative to the first surrounding rib 2, the stress point is caused to generate larger change, and in the embodiment, the width of the second surrounding rib 9 is equal to the width of the first surrounding rib 2. Preferably, the width of the second peripheral bone 9 is greater than the width of the first peripheral bone 2, so that the first peripheral bone 2 and the second peripheral bone 9 are maintained in a corresponding relationship even if the second peripheral bone 9 is deformed by a certain amount.

Further, in the length direction of the housing 1, the distance between the adjacent connection studs 5 is greater than 30mm, in this embodiment, the distance between the adjacent connection studs 5 in the length direction of the housing 1 is 48.18±0.01mm, and the distance between the adjacent connection studs 5 in the width direction of the nameplate hole 4 is 50.67 ±0.01mm. . The housing 1 is made of plastic, and the thickness of the housing is not easy to be too thin, so that the thickness of the housing 1 is greater than or equal to 1.6mm in the embodiment.

Since the first surrounding rib 2 protrudes from the inner side of the housing 1, the space inside the housing 1 is reduced by the first surrounding rib 2. Meanwhile, the width of the first surrounding rib 2 influences the contact area with the silica gel key 6, so that the waterproof effect and the key hand feeling are influenced, and the width of the first surrounding rib 2 is not easy to be too small. Therefore, under the condition that enough space is reserved in the shell 1, the width of the first surrounding rib 2 is more than or equal to 1.8mm, so that the silica gel key 6 can bear force and keep certain key hand feeling. In order to enable the second surrounding bone 9 to still keep corresponding to the first surrounding bone 2 after being pressed, the second surrounding bone 9 is wider than the first surrounding bone 2 by 0.2mm on one side in the embodiment.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
