Abstract

A case comprises a case body, a case cover, and a snap-fitting assembly comprising a snap-fitting member and a connecting member for fastening the case cover and the case body. The connecting member comprises a first end and a second end opposite to each other. The first end of the connecting member is rotatably connected to one of the case body and the case cover. The other one of the case body and the case cover is provided with a snapping block. The second end of the connecting member is rotatably connected to the snap-fitting member. The snap-fitting member comprises a snapping part configured to be snapped with the snapping block.

First claim

What is claimed is:

1. A case, comprising:
a case body;
a case cover; and
a snap-fitting member and a connecting member for fastening the case cover and the case body, wherein:
the connecting member comprises a first end and a second end, the first end of the connecting member being rotatably connected to one of the case body and the case cover, and the second end of the connecting member being rotatably connected to the snap-fitting member,
the other one of the case body and the case cover comprises a snapping block,
the snap-fitting member comprises:
a snapping part configured to be snapped with the snapping block,
a first plate body rotatably connected to the second end of the connecting member and a second plate body extending from one side of the first plate body,
a protrusion connected to the second plate body and extending to the first plate body, the snapping part extending perpendicularly from the protrusion, and

the snap-fitting member covers the connecting member on an outer surface of the case when the case cover and the case body are fastened.

2. The case of claim 1 , wherein:
the snapping part is formed on and extends from one side of the second plate body away from the first plate body.

3. The case of claim 2 , wherein:
the snapping block comprises a slot, and
the snapping part comprises a lock catch formed on and protruding from a side of the snapping part facing the first plate body, the lock catch being configured to snap in the slot of the snapping block.

4. The case of claim 1 , wherein the snapping block is arranged on the case body and the first end of the connecting member is rotatably connected to the case cover.

5. The case of claim 4 , wherein:
the case body comprises a first side wall and a second side wall opposite to the first side wall,
the case cover comprises a first installation wall and a second installation wall opposite to the first installation wall,
the snapping block is arranged on an outer side surface of the first side wall,
the first end of the connecting member is rotatably connected to the first installation wall, and
the second installation wall is rotatably connected to the second side wall.

6. The case of claim 5 , wherein the first side wall comprises two stopping sheets arranged at two sides of the snapping block.

7. The case of claim 5 , wherein:
the first installation wall comprises a pair of pivoting blocks arranged on an outer side surface of the first installation wall,
the first end of the connecting member is located between the pivoting blocks and comprises a perforated hole, and
each of the pivoting blocks comprises a rotating shaft extending from a side of the pivoting block facing the other pivoting block, the rotating shaft being snapped in one end of the perforated hole.

8. The case of claim 7 , wherein:
the stopping sheets are first stopping sheets, and
the first installation wall further comprises two second stopping sheets arranged on the outer side surface of the first installation wall at two sides of the pair of pivoting blocks.

9. The case of claim 7 , wherein:
the perforated hole is a first perforated hole,
the first plate body comprises two extension parts extending from two ends of the first plate body, respectively, each of the extension parts comprising a through hole,
the second end of the connecting member is located between the two extension parts of the snap-fitting member and comprising a second perforated hole, and
the snap-fitting member and the connecting member are rotatably connected via a pin inserted in the through holes of the two extension parts of the snap-fitting member and the second perforated hole on the second end of the connecting member.

10. The case of claim 5 , further comprising two hinges rotatably connecting the second installation wall to the second side wall.

11. The case of claim 1 , further comprising:
a power source installed on the case cover or the case body, the power source comprising a rechargeable battery, a power source port, and a cable electrically connected to the power source port and the rechargeable battery, the rechargeable battery and the cable being embedded in the case cover, and the power source port being fixed on the case cover and exposed.

12. The case of claim 11 , wherein the case cover comprises:
a rectangular top wall, the rechargeable battery being embedded in the top wall;
a first installation wall and a second installation wall opposite to each other, the second installation wall being rotatably connected to the case body; and
two connecting walls extending from two edges of the top wall, respectively, and opposite to each other.

13. The case of claim 12 , wherein the power source port is fixed on the first installation wall of the case cover, and the cable is embedded in the top wall and the first installation wall.

14. A snap-fitting assembly, comprising:
a snap-fitting member comprising:
a first plate body;
a second plate body extending from the first plate body; and
a snapping part extending from an end of the second plate body away from the second plate body and bent toward the first plate body;
a protrusion connected to the second plate body and extending to the first plate body, the snapping part extending perpendicularly from the protrusion; and

a connecting member, one end of the connecting member being rotatably connected to an end of the first plate body away from the second plate body.

15. The snap-fitting assembly of claim 14 , wherein the snapping part is perpendicular to a top surface of the second plate body, and the first plate body has a curved shape.

16. The snap-fitting assembly of claim 14 , wherein:
the snap-fitting member further comprises two extension parts extending perpendicularly from two ends of the first plate body, respectively, and
the connecting member is rotatably connected between the two extension parts.

17. The snap-fitting assembly of claim 14 , wherein the snapping part comprises a lock catch formed on and protruding from a side of the snapping part facing the first plate body.

18. The snap-fitting assembly of claim 17 , wherein a cross-section of the lock catch has an arch shape.
