Abstract

A case includes a housing, a cover and a switch module with a secure mechanism. The case has an accommodation portion. The cover is disposed on the case to have a cover position. The cover covers the accommodation portion. The switch module including a pressing switch and a switch-changing element is located in the accommodation portion and connected to the housing. The switch-changing includes a first pivot part, a pressing part, and a stop part. The first pivot part pivots the housing. The pressing part and the stop part jut from the first pivot part along different radial directions. The switch-changing element has a test position and a non-test position for rotating relative to the housing. When the switch-changing element locates at the test position, a position of the position of the stop part overlaps the cover position.

First claim

What is claimed is:

1. A case, comprising:
a housing having an accommodation portion; and
a cover which is detachably connected to the housing to have a cover position, wherein the cover covers the accommodation portion when the cover is in the cover position; and
a switch module connected to the housing and located in the accommodation portion, comprising:
a pressing switch for being pressed to have a turn-on state; and
a switch-changing element comprising a first pivot part, a pressing part and a stop part, wherein the first pivot part is pivoted on the housing, the pressing part and the stop part jut out from the first pivot part along different radial directions, the switch-changing element is configured to rotate relative to the housing to have a test position and a non-test position; when the switch-changing element is in the test position, the pressing part presses the pressing switch so that the pressing switch is in the turn-on state and a position of the stop part overlaps the cover position to prevent the cover from being disposed on the housing; when the switch-changing element is in the non-test position, the pressing part is out from the switch-changing element and the position of the stop part does not overlap with the cover position to make the cover be capable of being disposed on the housing.

2. The case according to claim 1 , wherein the cover presses the pressing switch to make the pressing switch be in the turn-on state.

3. The case according to claim 1 , wherein the first pivot part has an adjusting structure configured for letting a tool to adjust the rotating location of the switch-changing element.

4. The case according to claim 1 , wherein the case comprises a bottom plate and a plurality of side plates, the side plates are connected to the bottom plate to define the accommodation portion, each of the side plates has a first assembly region respectively, the cover contacts the first assembly region when being in the cover position, the position of the stop part overlaps the cover position to prevent the cover from being disposed on the cover position when the switch-changing element is in the test position, the stop part moves out from the cover position to make the cover in the cover position when the switch-changing element is in the non-test position.

5. The case according to claim 1 , wherein the cover is a wind shield, the accommodation portion is sealed by the cover and the housing.

6. The case according to claim 1 , further comprising a lid, wherein the housing comprises a bottom plate, a separating plate and a plurality of side plates, the side plates are connected to the bottom plate, opposite two sides of the separating plate are connected to two of the side plates to define a fans accommodating space and the accommodation portion, the switch module is located in the accommodation portion, the cover is assembled with the side plates and the separating plate to cover the accommodation portion, the lid is assembled with the side plates to cover the cover and the fans accommodating space.

7. The case according to claim 1 , further comprising a lid, wherein the lid is detachably disposed on an assembling position of the housing, the cover has a holding part, the switch module further comprises a fool-proof element which comprises a second pivot part, a convex part and a blocking part, the convex part and the blocking part jut out from the second pivot part, the fool-proof element rotates relative to the housing around a pivot point as a centerline and therefore has a starting position and a pressed position, the convex part overlaps the assembling position to prevent the lid from being disposed on the housing when the fool-proof element is located at the starting position, the holding part of the cover presses the blocking part to drive the fool-proof element to pivot from the starting position to the pressed position when the cover is connected to the housing, which makes the fool-proof element does not overlap the assembling position and the lid is capable of being connected to the housing.

8. The case according to claim 7 , wherein the second pivot part has a pivot point, the convex part has a stop point, the blocking part has a blocking point, the cover and the lid are connected to the housing along an assembling direction; a line from the pivot point to a first touching point is parallel to the assembling direction when the fool-proof element is located at the starting position, and a line from the pivot point to a second touching point encloses an acute angle with the assembling direction.

9. The case according to claim 7 , wherein the switch module further comprises an elastic element which abuts on the housing and the fool-proof element to make the fool-proof element be located at the starting position.

10. The case according to claim 7 , wherein the side plates have a second assembly region respectively, the lid contacts the second assembly region when locating at the assembling position, the fool-proof element juts out from the second assembly region when locating at the starting position, and the fool-proof element does not jut out from the second assembly region when locating at the pressed position.

11. A switch module with a secure mechanism configured to be connected to a housing and located in an accommodation portion, wherein a cover and a lid are assembled with the housing, the cover covers the accommodation portion to have a cover position, the lid covers the cover, the switch module with the secure mechanism comprising:
a pressing switch for being pressed to have a turn-on state; and
a switch-changing element including a first pivot part, a pressing part and a stop part, wherein the first pivot part is pivoted on the housing, the pressing part and the stop part jut out from the first pivot part along different radial directions, the switch-changing element is configured to rotate relative to the housing to have a test position and a non-test position; when the switch-changing element is in the test position, the pressing part presses the pressing switch to make the pressing switch be in the turn-on state and a position of the stop part overlaps the cover position to prevent the cover from being disposed on the housing, when the switch-changing element is in the non-test position, the pressing part moves out from the switch-changing element and the position of the stop part does not overlap the cover position to make the cover be capable of being disposed on the housing.

12. The switch module with the secure mechanism according to claim 11 , wherein the cover presses the pressing switch to make the pressing switch be in the turn-on state.

13. The switch module with the secure mechanism according to claim 11 , wherein the first pivot part has an adjusting structure, the adjusting structure is configured for letting a tool to adjust a rotating location of the switch-changing element.

14. The switch module with the secure mechanism according to claim 11 , further comprising a fool-proof element which comprises a second pivot part, a convex part and a blocking part, wherein the cover has a holding part, the convex part and the blocking part both jut out from the second pivot part, the second pivot part has a pivot point, the convex part has a first touching point contacting the lid, the blocking part has a second touching point contacting the holding part, the fool-proof element rotates relative to the housing around a pivot point as a centerline and has a starting position and a pressed position, a position of the convex part overlaps an assembling position to prevent the lid from being disposed on the h
