The subject matter herein generally relates to locking mechanisms, and more particularly to a magnetic locking mechanism for locking and unlocking two housings.
Generally, a cover is fixed to a housing by screws. However, it may be inconvenient to assemble or remove the cover fixed to the housing by screws. Even though there are structures on the market for automatically locking a cover to a housing, the automatic locking structure may be easily unlocked, so that the automatic locking structure may not have an effective locking function.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached FIGs.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different FIGS. 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 “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.

When the locking member 30 is moved to a predetermined position in a direction of the guiding member 12, the telescopic rod 32 protrudes into the first through hole 129, and the second housing 20 is locked to the first housing 10. When the unlocking member 40 adsorbs the locking member 20 protruded into the first through hole 129, the telescopic rod 32 is retracted from the first through hole 129, and the second housing 20 is unlocked from the first housing 10.

The first inclined portion 122, the second inclined portion 123, and the third inclined portion 124 are all inclined toward an inner side of the first housing 10. The first protruding portion 126 and the second protruding portion 127 protrude toward an inner side of the first housing 10 and are substantially parallel to the first side wall 11. In one embodiment, the first protruding portion 126 and the second protruding portion 127 are not in the same plane, and a distance between the first protruding portion 126 and the first sidewall 11 is greater than a distance between the second protruding portion 127 and the first side wall 11, such that the locking member 30 has sufficient space between the first side wall 11 and the guiding member 12 and continue to move along the guiding member 12. The first through hole 129 is defined in the second protruding portion 127 to cooperate with the locking member 30. It can be understood that, in other embodiments, the inclined portions and the protruding portions of the guiding member 12 may be replaced with other structures according to the structure of the locking member 30. For example, the first protruding portion 126 and the second protruding portion 127 can be in the same plane. At this time, a length of the locking member 30 should be increased, and a position of the first through hole 129 can be adjusted accordingly. The guiding member 12 may be integrally formed with the first housing 10.

The fixing portion 31 is substantially cylindrical and includes a second through hole 313 extending from a third end 311 to an opposite fourth end 312. In one embodiment, the third end 311 is provided with a groove (not shown). The groove latches the bent portion 21. The third end 311 is further provided with a first abutting portion 314 located on an inner side of the third end 311. The first abutting portion 314 is configured to abut the telescopic rod 32 and the resilient member 33. A second abutting portion 315 is located on an inner side of the fourth end 312, and the second abutting portion 315 is configured to abut the telescopic rod 32. Further, a length of the first abutting portion 314 extending along a center line of the fixing portion 31 is greater than a length of the second abutting portion 315.
The telescopic rod 32 includes a first end A and a second end B opposite to the first end A. The diameter of the telescopic rod 32 increases from the first end A to the second end B to match the first abutting portion 314 and the second abutting portion 315. The first end A is correspondingly located at the third end 311 and can protrude from the third end 311. The second end B is correspondingly located at the fourth end 312 and can protrude from the fourth end 312. The telescopic rod 32 includes a third abutting portion 321 located about ⅓ from the first end A to the second end B, and includes a fourth abutting portion 322 located about ⅔ from the first end A to the second end B. The third abutting portion 321 is configured to abut the first abutting portion 314, and the fourth abutting portion 322 is configured to abut the second abutting portion 315 and the resilient member 33.
The two ends of the resilient member 33 respectively abut the first abutting portion 314 and the fourth abutting portion 322, and a resilient force of the resilient member 33 drives the telescopic rod 32 to move within the fixing portion 31. The resilient member 33 may be a spring. It can be understood that the resilient member 33 can also be replaced with other structures having a similar effect or function. In order to avoid offsetting the resilient member 33 in the fixing portion 31, two ends of the resilient member 33 can be respectively embedded on the fixing portion 31 and the telescopic rod 32, so that the fixing portion 31 and the telescopic rod 32 are not easily detached.

When the second housing 20 is to be unlocked from the first housing 10, the unlocking member 40 is aligned with the locking member 30, and the magnetic member 42 adsorbs the telescopic rod 32. The telescopic rod 32 moves toward the third end 311, the first end A protrudes out of the third end 311, and the second end B is received in the fixing portion 31, the third abutting portion 321 abuts the first abutting portion 314, and the resilient member 33 is compressed. At this time, the second housing 20 can be unlocked from the first housing 10 as shown in

The actuation process of the second embodiment is substantially the same as the actuation process of the first embodiment, and will not be further described herein.
In summary, the magnetic locking mechanism 100 provides a locking structure on the first housing 10 and the second housing 20, that is, the locking member 30 arranged on the second housing 20 inserts through the first through hole 129 of the guiding member 12 to lock the two housing together. The unlocking member 40 adheres the locking member 30 to cause the locking member 30 to remove from the first through hole 129 to unlock the two housings. The magnetic locking mechanism 100 has a simple structure, and the two housings are not required to be locked or unlocked by screws. It can be understood that the magnetic locking mechanism 100 can also be used on other structures that need to be locked.
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.
