In some examples, the compact housing assembly 1 may include a housing 10 and a snap-on cover 20. In some examples, the snap cover 20 may be removably fitted to the housing 10. In some examples, the housing 10 may have a window 11. The engaging cover 20 is fitted to the housing 10 so as to engage with the window 11.

Fig. 4A is a schematic view showing the compact case assembly 1 according to the embodiment of the present invention in a closed state. Fig. 4B is a schematic view showing the compact case assembly 1 according to the embodiment of the present invention in an open state.

In some examples, one face of the housing 10 is perforated to form a window 11. In some examples, an inner edge 12 of the window 11 on the side of the inner wall of the housing 10 protrudes from an outer edge 13 on the side of the outer wall of the housing 10 in a direction facing the center of the window installation surface. That is, the cross section of the window 11 may be substantially stepped in a cross section along the direction in which the window 11 faces. In some examples, the inner edge 12 and the outer edge 13 may form a retaining groove 14 of the snap cover 20. The engaging cover 20 engages with the stopper groove 14 to cover the window 11.

In some examples, one side of the snap cover 20 forms a rotating portion 21. In some examples, the rotating portion 21 may present a concave structure. In some examples, the inward edge 12 of the recess of the concave structure. In some examples, the inner wall side of the housing 10 and the outer wall side of the housing 10 are wrapped around the inner edge 12 of the window 11, and the inner edge 12 of the window 11 is matched to realize that the snap cover 20 is turned over within a preset degree. In some examples, when the concave structure contacts with a portion of the inner edge 12 facing the inside of the housing 10, the compact housing component 1 may be in a closed state, that is, the engaging cover 20 is mostly engaged with the limiting groove 14. When the concave structure contacts the portion of the inner edge 12 facing the outside of the housing 10, the compact housing 1 can be in an open state, i.e. the inside of the compact housing 1 can be exposed and the parts inside can be replaced.

In the present invention, the engagement cover 20 is detachably attached to the window 11 of the housing 10, and most of the engagement cover 20 is engaged with the stopper groove 14 formed in the outer edge 13. The engagement cover 20 further includes a rotating portion 21 on one side. The rotating portion 21 may be engaged with the inner edge 12 of the case 10 in a concave structure, and the engaging cover 20 may be rotated in such a manner that the rotating portion 21 rotates around the inner edge 12.

Fig. 5A is a detailed view showing a first perspective of the snap cover 20 according to the embodiment of the present invention. Fig. 5B is a detailed view showing a second perspective of the snap cover 20 according to the embodiment of the present invention. Fig. 6 is a detailed view showing the window 11 of the housing 10 according to the embodiment of the present invention.

In some examples, the concave structure of the rotating part 21 may include: the cover edge 211, the cover edge 211 forms a first side wall of the concave structure. In some examples, the cover edge 211 may be an end of the snap cover 20 on the same side as the rotating part 21. In some examples, the cover edge 211 may be thinner as it gets closer to the edge and the cover edge 211 and the housing 10 constitute a flat surface after the snap cover 20 covers the window 11. In this case, the cover edge 211 is gradually spaced from the inner edge 12 in an extending direction toward the edge to form a concave structure and a rotation space of the inner edge 12.

In some examples, the concave structure of the rotating part 21 may include: recessed bottom 212. The recessed bottom 212 may form the bottom of the concave structure. The recessed bottom 212 may be located on a side of the inner wall of the snap cover 20 closer to the snap cover 20 than the cover rim 211. In some examples, the recessed bottom 212 may abut the inner edge 12 of the window 11. Thus, the recessed bottom portion 212 and the cover edge 211 can have an inner concave structure.

In some examples, the concave structure of the rotating part 21 may further include: a stopper protrusion 213. In some examples, the stop protrusion 213 forms a second sidewall of the concave structure. The stopper protrusion 213 may be an extension of the inner wall of the snap cover 20. Thus, the stopper protrusion 213 located on the inner side, the cover edge 211 located on the outer side, and the recessed bottom 212 can form a recessed structure to be engaged with the inner edge 12.

In some examples, the number of the stopper protrusions 213 may be two, three, or four. At least two of the stopper protrusions 213 may be provided at intervals. This allows the stopper projection 213 to be easily engaged with the inner wall of the housing 10. In some examples, the compact housing assembly 1 may be in a closed state when the inner walls of the housing 10 contact the stop protrusion 213. In some examples, when the stop protrusion 213 contacts the inner wall of the housing 10, the outer surface of the housing 10 and the outer surface of the snap-on cover 20 may be substantially flush.

In some examples, the concave structure of the rotating part 21 may include: a lid edge protrusion 214. In some examples, the lid edge protrusion 214 may form a first sidewall of the concave structure. The lid edge protrusion 214 is an extension that engages the outer wall of the lid 20. Thus, the inward-located stopper projection 213, the outward-located cover rim projection 214, and the recessed bottom 212 can be engaged with the inner edge 12 in a recessed structure.

In some examples, the number of lid edge projections 214 may be two, three, four, five, or six. More than two cover rim protrusions 214 may be provided at intervals. Thus, the cover rim protrusion 214 can be easily engaged with the inner rim 12.

In some examples, the cover rim protrusions 214 and the stopper protrusions 213 may be staggered.

In some examples, the snap cover 20 may further include an opening and closing catch 22 provided at an opposite side of the rotation portion 21. That is, in some examples, the opening and closing catch 22 and the rotating part 21 may be respectively located at both ends of the snap cover 20. In some examples, the opening and closing snaps 22 may be provided to the inner wall of the snap cover 20. The open/close latch 22 is inserted from the outer wall side of the housing 10 and abuts against the inner wall side of the housing 10 in the process of covering the window 11 with the latch cover 20. In this case, when the engaging cover 20 is engaged with the housing 10, the opening/closing hook 22 can improve the stability of the engaging between the engaging cover 20 and the housing 10.

In some examples, the outer wall of the snap cover 20 may be provided with an opening and closing protrusion 23. In some examples, the opening and closing protrusion 23 may function to facilitate the opening of the snap cover 20. The opening and closing protrusion 23 can be matched with the opening and closing groove 15 arranged on the outer wall of the shell 10 to realize the opening of the clamping cover 20. Thus, the engaging cover 20 can be easily rotated or removed by the opening and closing protrusion 23.

In some examples, snap cover 20 may further include a snap carrier 24, and an opening and closing snap 22 disposed on snap carrier 24. In some examples, the snap bearing 24 may be disposed perpendicular to the plane of the snap lid 20 and extend inward starting from the inner wall of the snap lid 20. In some examples, the opening catch 22 may be disposed in a direction extending toward an edge of the snap cover 20 in a direction perpendicular to the catch carrier 24.

According to the present invention, it is possible to provide a compact case assembly 1 that is easy to assemble and disassemble.
