The subject matter herein generally relates to a fastening structures, and more particularly to a waterproof fastening assembly.
In a device such as a smart doorbell, when a battery of the smart doorbell needs to be replaced, a housing of the smart doorbell is first opened to remove the battery. However, a waterproof structure of the smart doorbell is generally difficult to disassemble, making it difficult to replace the battery. An improved waterproof structure is desired to enable easy opening and closing of the housing.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series and the like.
As shown in
The receiving space 40 is sealed when the housing 50 is covered over the receiving space 40, and the housing 50 can be opened and closed conveniently. The housing 50 is opened and closed by the fastening structure 30.

The fixing seat 36 is arranged at the second opening 222. The elastic latch 32 and the limiting slider 34 are arranged at the first opening 221. The fixing seat 36 includes at least one guiding rod 361 extending into the slot 22. The guiding rod 361 is configured to sleeve an elastic member 38 to elastically mount the elastic latch 32 on the fixing seat 36. In one embodiment, the guiding rod 361 includes two first guiding rods 3611 and a second guiding rod 3613. The first guiding rods 3611 are received through a hole 321 of the elastic latch 32 to guide elastic displacement of the elastic latch 32 on the fixing seat 36. The second guiding rod 3613 sleeves the elastic member 38 to apply an elastic force of the elastic member 38 on the elastic latch 32. The elastic latch 32 is biased by the elastic force of the elastic member 38 to abut against the limiting slider 34, and the limiting slider 34 is held in the first opening 221 of the slot 22.
A latching structure 33 is formed by the elastic latch 32 and the limiting slider 34. The latching structure 33 includes at least one protrusion 331 and at least one recess 333. The protrusion 331 is formed on a surface of the elastic latch 32, and the recess 333 is defined in a surface of the limiting slider 34 facing the elastic latch 32. When the elastic latch 32 abuts against the limiting slider 34 to insert the protrusion 331 into the recess 333 (as shown in
In one embodiment, the limiting slider 34 defines a guiding groove 341 for guiding the elastic latch 32 to protrude through the first opening 221. An inner edge surface of the guiding groove 341 forms a pushing surface 343. By sliding the limiting slider 34, the pushing surface 343 drives the elastic latch 32 to retract into the slot 22 (as shown in

To assemble the housing 50 to the top cover 20, the housing 50 is first engaged with the top cover 20 such that the fastening hole 52 is aligned with the first opening 221. Then, the limiting slider 34 is driven to slide to align the guiding groove 341 of the limiting slider 34 with the elastic latch 32, and the elastic latch 32 is driven by a restoring force of the elastic member 38 to protrude from the guiding groove 341 through the first opening 221 to latch the housing 50 to the top cover 20. A joint between the top cover 20 and the housing 50 is located at a periphery of an outer surface of the top cover 20, and the first soft waterproofing sealant 201 is disposed on the periphery of the outer surface of the top cover 20. The first waterproofing sealant 201 is located opposite to a periphery of a joint end of the housing 50. The second waterproofing sealant 203 is disposed on a periphery of the receiving space 40 between the base plate 10 and the top cover 20 (as shown in
The housing 50 is latched and unlatched by the elastic latch 32 and the limiting slider 34 to facilitate opening and closing of the receiving space 40. Thus, the waterproof fastening assembly 100 has a simple structure.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
