Abstract

An electronic apparatus combined with a magnetic attraction force includes a first body and a second body. The first body includes at least one first magnetic element, and the second body includes at least one receiving groove, at least one moving assembly, and at least one assistant magnetic element. Each moving assembly is movably disposed in each receiving groove, and each moving assembly includes a second magnetic element. Each assistant magnetic element is fixed in the receiving groove, and the magnetic attraction force between the assistant magnetic element and the second magnetic element is smaller than that between the first magnetic element and the second magnetic element. When the second body is combined with the first body, each second magnetic element is attracted by each first magnetic element, such that each moving assembly is driven to move toward the first body.

Claims

1. An electronic apparatus combined with magnetic attraction force, comprising:

a first body including a first combination side and at least one first magnetic element, wherein each first magnetic element is disposed on the first combination side;

a second body including a second combination side combined with the first combination side, at least one receiving groove, at least one moving assembly, and at least one assistant magnetic element, wherein the at least one receiving groove is disposed on the second combination side, each moving assembly is movably disposed in the receiving groove and comprises a second magnetic element, the assistant magnetic element is fixed in the receiving groove and far away from the second combination side, and the magnetic attraction force between the assistant magnetic element and the second magnetic element is smaller than that between the first magnetic element and the second magnetic element, wherein each moving assembly further has a support and the second magnetic element is combined with the support, wherein the support is able follow the second magnetic element as the second magnetic element moves in the at least one receiving groove, wherein each moving assembly further comprises at least one damper element to provide a buffering effect on contact of each moving assembly with the second combination side;

wherein when the second body is not combined with the first body, each second magnetic element is attracted by each assistant magnetic element to fix each moving assembly,

wherein when the second combination side of the second body is combined with the first combination side of the first body, each second magnetic element is attracted by each first magnetic element to separate from the assistant magnetic element such that each moving assembly can move toward the second combination side.

2. The electronic apparatus combined with magnetic attraction force as claimed in claim 1, wherein each damper element is fixed on each second magnetic element or each support and is closer to the second combination side than to each second magnetic element or each support.

3. An electronic apparatus combined with magnetic attraction force, comprising:

a first body including a first combination side and at least one first magnetic element, wherein each first magnetic element is disposed on the first combination side;

a second body including a second combination side combined with the first combination side, at least one receiving groove, at least one moving assembly, and at least one assistant magnetic element, wherein the at least one receiving groove is disposed on the second combination side, each moving assembly is movably disposed in the receiving groove and comprises a second magnetic element, the assistant magnetic element is fixed in the receiving groove and far away from the second combination side, and the magnetic attraction force between the assistant magnetic element and the second magnetic element is smaller than that between the first magnetic element and the second magnetic element, wherein the second body further comprises at least one second upper cover and each second upper cover is used for being fixed on each receiving groove for shielding each receiving groove;

wherein when the second body is not combined with the first body, each second magnetic element is attracted by each assistant magnetic element to fix each moving assembly,

wherein when the second combination side of the second body is combined with the first combination side of the first body, each second magnetic element is attracted by each first magnetic element to separate from the assistant magnetic element such that each moving assembly can move toward the second combination side.

4. The electronic apparatus combined with magnetic attraction force as claimed in claim 3, wherein each moving assembly further has a support and the second magnetic element is combined with the support, and wherein the support is able follow the second magnetic element as the second magnetic element moves in the at least one receiving groove.

5. The electronic apparatus combined with magnetic attraction force as claimed in claim 4, wherein each support includes at least one guiding portion and the at least one receiving groove includes at least one corresponding guiding portion, wherein each support moves along a substantially linear direction in the at least one receiving groove by cooperation between each guiding portion and each corresponding guiding portion.

6. The electronic apparatus combined with magnetic attraction force as claimed in claim 5, wherein each guiding portion is a guiding rod and each corresponding guiding portion is a guiding groove for the guiding rod to pass along.

7. The electronic apparatus combined with magnetic attraction force as claimed in claim 3, wherein the first body further comprises at least one first positioning portion and the second body further comprises at least one second positioning portion corresponding to the at least one first positioning portion to provide an auxiliary positioning effect of combining the first body and the second body by cooperation between each first positioning portion and each second positioning portion.

8. The electronic apparatus combined with magnetic attraction force as claimed in claim 7, wherein each first positioning portion is a recess and each second positioning portion is a tenon inserted into the recess.

9. The electronic apparatus combined with magnetic attraction force as claimed in claim 3, wherein the first combination side is an inclined structure and the second combination side is an another inclined structure corresponding to the inclined structure of the first combination side.
