Electronic device with detachable power module
View Patent ↗An electronic device includes a casing with a side plate and encasing a power module. The power module includes a locking member, a sliding member, and an elastic member sandwiched between the base and the cover. The sliding member is movable relative to the locking member between a locked position in which the locking portion of the locking member is pushed by the elastic member to extend through the cover to be blocked by the side plate of the casing, and an unlocked position in which the locking member is pressed by the sliding member to withdraw from the side plate to allow removal of the power module from the casing.
1. An electronic device, comprising:
a casing comprising a side plate; and
a power module attached to the side plate of the casing, the power module comprising:
a base;
a cover engaged with the base;
a connector mounted between the base and the cover;
a sliding member sandwiched between the base and the cover and defining a through slot;
a locking member comprising a main body movably received in the base, and a locking portion connecting the main body and extending through the slot of the sliding member; and
an elastic member sandwiched between the main body of the locking member and the base;
wherein the sliding member is movable relative to the locking member between a locked position in which the locking portion of the locking member is pushed by the elastic member to extend through the cover to be blocked by the side plate of the casing, and an unlocked position in which the locking member is pressed by the sliding member to withdraw from the side plate to allow removal of the power module from the casing.
2. The electronic device of claim 1 , wherein the main body of the locking member has an inclined contact surface, the sliding member comprising a contact end in the slot to press the contact surface of the locking member away from the cover in the unlocked position.
3. The electronic device of claim 1 , wherein the sliding member comprises a body, an operating portion connecting one end of the body, and an inserting portion connecting the other end of the body and opposite to the operating portion, the slot being defined through the body.
4. The electronic device of claim 3 , wherein the base comprises a fixing member retaining the inserting portion when the inserting portion is pushed towards the fixing member at a first time, and pushing the inserting portion to separate away from the fixing member when the inserting portion is pushed towards the fixing member at a second time.
5. The electronic device of claim 1 , wherein the sliding member has a concave portion and the base comprises a latching portion elastically engaged in the concave portion when the sliding member is in the unlocked position.
6. The electronic device of claim 1 , wherein the slot of the sliding member extends lengthways and the concave portion of the sliding member extends transversely.
7. The electronic device of claim 1 , wherein the main body of the locking member defines a blind hole at a bottom thereof to receive the elastic member.
8. The electronic device of claim 7 , wherein the elastic member is a spring.
9. An electronic device, comprising:
a casing; and
a power module received in the casing, the power module comprising:
a base;
a cover engaged with the base;
at least a connector mounted between the base and the cover;
a sliding member sandwiched between the base and the cover;
a locking member movably received in the base, the locking member comprising a locking portion extending through the sliding member; and
an elastic member sandwiched and pressed between the locking member and the base, the elastic member pushing the locking member to space apart from the base;
wherein the sliding member is movable relative to the locking member between a locked position in which the locking portion of the locking member is pushed by the elastic member to extend through the cover to be blocked by the side plate of the casing, and an unlocked position in which the locking member is pressed by the sliding member to withdraw from the side plate to allow removal of the power module from the casing.
10. The electronic device of claim 9 , wherein the locking member has an inclined contact surface, the sliding member comprising a contact end to press the contact surface of the locking member away from the cover in the unlocked position.
11. The electronic device of claim 9 , wherein the sliding member comprises a body, an operating portion connecting one end of the body, and an inserting portion connecting the other end of the body and opposite to the operating portion.
12. The electronic device of claim 11 , wherein the base comprises a fixing member retaining the inserting portion when the inserting portion is pushed towards the fixing member at a first time, and pushing the inserting portion to separate away from the fixing member when the inserting portion is pushed towards the fixing member at a second time.
13. The electronic device of claim 9 , wherein the sliding member has a concave portion and the base comprises a latching portion elastically engaged in the concave portion when the sliding member is in the unlocked position.
14. The electronic device of claim 9 , wherein the locking member defines a blind hole at a bottom thereof to receive the elastic member.
