Description

Snap structure and electronic product using the same

The present invention relates to a snap structure, and more particularly to a snap structure for use in an electronic product to cover a battery slot.

Conventional electronic products such as mobile phones, digital cameras, PDAs, etc., mostly use batteries as their power source. The batteries are mostly detachable batteries. The electronic components are provided with a battery-assembled casing and a cover for the battery. The assembly is assembled with the cover body by snapping. However, if the cover body is pressed into the housing in a vertical direction, a finger position is required on the cover body to facilitate the user to open or close the cover body; if the cover body is slid into the housing in the horizontal direction, the cover body The finger position design can be omitted, but once the user mistakenly presses the cover body into the casing in a vertical direction, the buckle structure is easily damaged, and the cover body cannot be used.

In view of the above, it is necessary to provide a snap structure that can be slid into and pressed into the casing and an electronic product to which the buckle structure is applied.

A buckle structure includes a detachable snap-fit buckle and a hook, the buckle includes a receiving groove, a first inclined surface, a second inclined surface, and a third inclined surface, and the hook includes a first inclined surface and a second inclined surface The first inclined surface of the hook slides along the first inclined surface of the buckle and the second inclined surface to guide the hook to slide into the receiving slot in the first direction and is engaged with the buckle, and the second inclined surface of the hook The third inclined surface of the buckle slides into the receiving slot to guide the hook to slide into the receiving slot from the second direction and is engaged with the buckle.

An electronic product comprising a cover body and a casing, the cover body comprising a buckle, the casing comprising a hook, the buckle and the hook are detachably snap-fitted to engage the cover body and the casing, the buckle comprises The receiving groove, the first inclined surface, the second inclined surface, and the third inclined surface, the hook comprises a first inclined surface and a second inclined surface, and the first inclined surface of the hook slides along the first inclined surface and the second inclined surface of the buckle The guide hook is slid into the receiving slot in the first direction and is engaged with the buckle. The second inclined surface of the hook slides into the receiving slot along the third inclined surface of the buckle to guide the hook to slide into the receiving slot from the second direction. And with the buckle card.

The first sliding surface and the second inclined surface of the buckle are sequentially slid by the first inclined surface of the hook, and the buckle is guided to be engaged in the hook, so that the user is in the vertical direction, that is, the thickness of the electronic product. Direction, the cover body is mounted on the casing; the third inclined surface of the buckle slides along the second inclined sliding surface of the hook, guiding the buckle to be engaged into the hook, so that the user is in the horizontal direction, that is, the electronic In the longitudinal direction of the product, the cover body is mounted on the casing; the above method realizes that the user assembles the cover body to the casing in multiple directions, so as to prevent the buckle from being broken when the user presses the cover body vertically into the casing due to an erroneous operation. At the same time, the reinforcing rib is designed between the two buckles to increase the strength of the buckle and avoid the buckle from breaking. The cover body is assembled into the casing in a sliding manner, and no need to set a finger position, thereby reducing the design cost. The invention has simple structure and reasonable design.
