Description

Locking mechanism

The present invention relates to an engaging mechanism, and in particular to an engaging mechanism capable of combining two objects and causing the two objects to rotate relative to each other.

In the prior art, the combination structure that connects two products and the rotation structure that enables the two products to rotate relative to each other are usually designed as two separate mechanisms. The two products must first be connected through the combination structure, and then use the rotation structure to perform relative rotation. The internal space of the two products needs to be large enough to accommodate the two structures at the same time. Therefore, it will be compressed into the accommodation space required for other components, causing inconvenience in the overall design of the product. In addition, since the combining structure and the rotating structure are two different mechanism designs, there are many structural materials, which also relatively increases the manufacturing cost.

Therefore, how to integrate the combined structure and the rotating structure through structural design improvements to overcome the above-mentioned defects has become one of the important issues to be solved in this field.

The present invention mainly aims at the shortcomings of the prior art to provide an engaging mechanism that can combine two objects and make the two objects rotate relative to each other, so as to solve the technical problems in the prior art that the combining structure and the rotating structure cause many inconveniences due to different structural designs.

In order to solve the above technical problems, one of the technical solutions adopted by the present invention is to provide an engaging mechanism for combining a first housing and a second housing with an opening. The locking mechanism includes a hook structure and a rotating structure. The hook structure is provided on the first housing, and the rotating structure is provided on the second housing. The rotating structure includes a fixed frame, a rotating disk and a plurality of limiting components. The fixed frame is disposed inside the second housing and surrounds the opening. The fixed frame includes a plurality of stops. The rotating disk is rotatably disposed between the fixed frame and the second housing and is exposed through the opening. A through hole is opened in the part of the rotating disk that is exposed to the opening. The rotating disk has a plurality of limiting grooves and a plurality of stops. A plurality of limiting components are respectively arranged in a plurality of limiting grooves. When the hook structure passes through the through hole and abuts against the plurality of blocks, the first housing is used to drive the rotating disk through the plurality of blocks, so that the first housing rotates relative to the second housing.

The beneficial effect of the present invention is that the engaging mechanism provided by the present invention can pass through the through hole through the hook structure and resist against a plurality of stops, so that the first housing is combined with the second housing, and then the first housing is combined with the second housing through the hook structure. The hook structure drives the rotating disk to rotate together, causing the first housing to rotate relative to the second housing. Thereby, the engaging mechanism provided by the present invention integrates the hook structure and the rotating structure, so that the first housing and the second housing can not only be combined but also relatively rotate at the same time.

FIG. 16 is a schematic bottom view of FIG. 15 . When the rotating disk 22 stops rotating, since the first housing S1 can still continue to rotate at this time, the hammer-shaped portion 11 of the hook structure 1 will also rotate without resisting the two stops 222 and return to the hook. The state when the structure 1 has just been inserted into the through hole 220. Furthermore, at this time, the projection of the hammer-shaped portion 11 of the hook structure 1 on the rotating disk 22 will completely overlap the through hole 220 . After that, the user can pull out the hook structure 1 from the through hole 220 to separate the first housing S1 and the second housing S2 from each other to complete the disassembly step.

[Beneficial effects of the embodiment]

The beneficial effect of the present invention is that the engaging mechanism provided by the present invention can integrate the hook structure 1 and the rotating structure 2 . When the first housing S1 is combined with the second housing S2, it can be completed by inserting the hook structure 1 into the through hole 220 of the rotating disk 22 and rotating the first housing S1 along the first direction D1. Snap action. If you want to separate the first housing S1 from the second housing S2, you only need to rotate the first housing S1 in the opposite direction to complete the disassembly. Referring to FIG. 7 , the aforementioned electronic device having the first housing S1 may be, for example, a camera, and the other electronic device having the second housing S2 may be, for example, a projector. Through the engaging mechanism of the present invention, while the projector is fixedly projecting in one direction through the second illumination hole S21, the camera can rotate the first illumination hole S11 to a desired shooting angle.

Furthermore, when the user wants to combine the first housing S1 with the second housing S2, the hook structure 1 can be inserted into the through hole 220 of the rotating disk 22, and the first housing can be rotated along the first direction D1. body S1, so that the hammer-shaped portion 11 also rotates along the first direction D1 and abuts against the two stops 222, so as to drive the rotating disk 22 to rotate along the first direction D1, thereby completing the coupling action, allowing the first housing S1 to Rotates relative to the second housing S2.

Furthermore, when the user wants to disassemble the first housing S1 from the second housing S2, the first housing S1 can be rotated in the second direction D2 (the opposite direction of the first direction D1) to move the lever. The fourth contact surface 2312 of the head 231A of 231 abuts against the second contact surface 2112 of one of the stop portions 211, thereby causing the rotating disk 22 to stop rotating. Since the first housing S1 still continues to rotate at this time, the hammer-shaped portion 11 of the hook structure 1 will also rotate and end the state of contacting the two stops 222, and return to the state where the hook structure 1 was just inserted through. The state of hole 220. After that, the user can pull out the hook structure 1 from the through hole 220 to separate the first housing S1 and the second housing S2 from each other to complete the disassembly step.
