Patent Application
20190124781
This application claims priority to Chinese Patent Application No. 201711010021.1 filed on Oct. 25, 2017, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to an opening and closing structure of a casing of an electronic device.
Generally, a casing of an electronic device includes ports, such as an audio port, a USB port, or the like. The ports may be covered to prevent dust from entering the ports. A cover of the ports is usually hinge-coupled to an outer surface of the casing.
Implementations of the present disclosure will now be described, by way of example only, 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. In addition, 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 “substantially” is defined to be essentially conforming to the particular dimension, shape, or other word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. 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.
The electronic device 100 includes a casing 10 and an opening and closing structure 13. The casing 10 includes a bottom plate 101 and a peripheral wall 103. The peripheral wall 103 surrounds the bottom plate 101 to cooperatively define an accommodating space 105. The accommodating space 105 is used for accommodating electrical elements, such as a battery, an antenna, a circuit, or the like.
An outer surface of the casing 10 defines a groove 11. In at least one embodiment, the groove 11 is defined in the peripheral wall 103. A shape of the groove 11 can be round, oval, or any shape according to actual requirements.
The groove 11 includes at least one port 111. The port 111 serves to electrically couple the electronic device 100 to an external device and can be a universal serial bus (USB) port, an earphone port, a storage card port, or the like. A shape of the port 111 is determined according to the shape of a plug of the external device required to be coupled to the electronic device 100. In the illustrated embodiment, the groove 11 includes three ports 111, which are an earphone port, a storage card port, and a USB port.
A through hole 113 is defined in the groove 11 on opposite sides of the ports 111. The through holes 113 correspond to the opening and closing structure 13 to cover the groove 11, thereby achieving anti-dust functionality and a good appearance.
Referring to
A shape of the cover plate 131 corresponds to the shape of the groove 11. The cover plate 131 is mounted in the groove 11 by the connecting assembly 135 and covers the groove 11 to achieve anti-dust functionality.

Each of the first guiding member 1331 and the second guiding member 1333 define a sliding slot 1337. The sliding slots 1337 are substantially parallel and opposite to each other. The sliding slot 1337 is substantially rectangular with rounded ends. The sliding slots 1337 are oriented toward the cover plate 131.
The connecting assembly 135 includes a connecting rod 1351 and a connecting shaft 1353. The connecting rod 1351 includes a first end 1352 and a second end 1354. The connecting rod 1351 can pass through the corresponding through hole 113 such that the first end 1352 and the second end 1354 are at opposite sides of the through hole 113. The first end 1352 of the connecting rod 1351 is coupled to a side of the cover plate 131 facing the groove 11. The second end 1354 of the connecting rod 1351 is arranged in the casing 10 and slidably coupled to the sliding seat 133 through the connecting shaft 1353.
In detail, a connecting hole 1355 is defined through the second end 1354 of the connecting rod 1351. The second end 1354 is received within the receiving slot 1335 such that the connecting hole 1355 is aligned with the sliding slots 1337. Then, the connecting shaft 1353 is received through the sliding slot 1337 of the first guiding member 1331, the connecting hole 1355, and the receiving slot 1337 of the second guiding member 1333, thereby slidably coupling the second end 1354 of the connecting rod 1351 to the sliding seat 133. The connecting shaft 1353 allows the second end 1354 to slide along the sliding slots 1337, thereby allowing the cover plate 131 to open and close. The connecting shaft 1353 received through the second end 1354 of the connecting rod 1351 causes the connecting rod 1351 to rotate relative to the connecting shaft 1353. In at least one embodiment, the connecting shaft 1353 is a rotation shaft.
A length of the connecting rod 1351 can be adjusted to control an open angle of the cover plate 131 relative to the casing 10.

The opening and closing structure 13 is used for covering the groove 11 to achieve anti-dust functionality and a good appearance. The connecting assembly 135 is slidably coupled to the sliding seat 133 to allow the cover plate 131 to open and close relative to the casing 10. Assembly of the opening and closing structure 13 is simple. Operation is smooth, and the opening and closing structure 13 can be adapted for use in the casing 10 having any size. Furthermore, the connecting rod 1351 is received in the casing 10, thereby ensuring a good appearance of the casing 10.
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.
