Abstract

An electronic device with a latching assembly includes a housing, a battery cover, a circuit board, and a latching assembly. The battery cover includes a pair of hook portions. The circuit board is mounted in the housing. The latching assembly includes a touch element, a magnetic element, and a pair of latching elements. The touch element and the magnetic element are electrically connected to the circuit board. The latching elements are connected with two opposite ends of the magnetic element, respectively. The latching elements cooperate with the hook portions to secure the battery cover to the housing. When the touch element is touched, a touch signal is generated and transmitted to the circuit board, the circuit board charges the magnetic element in response to the touch signal, and when the magnetic element is charged, the magnetic element contract to cause the latching elements to disengage from the hook portions.

Claims

1. An electronic device with a latching assembly comprising:

a housing;

a battery cover comprising a pair of hook portions;

a circuit board mounted in the housing; and

a latching assembly comprising;

a touch element mounted in the housing and electrically connected to the circuit board;

a magnetic element mounted in the housing and electrically connected to the circuit board; and

a pair of latching elements connected with two opposite ends of the magnetic element, respectively, wherein the latching elements cooperate with the hook portions to secure the battery cover to the housing;

wherein when the touch element is touched, a touch signal is generated and transmitted to the circuit board, the circuit board charges the magnetic element in response to the touch signal, and when the magnetic element is charged, the magnetic element contract to cause the latching elements to disengage from the hook portions.

2. The electronic device as described in claim 1, wherein the latching assembly further comprises at least one resisting element, when the battery cover is secured to the housing, the at least one resisting element is compressed, and when the latching elements disengage from the hook portions, the at least one resisting element rebounds to push the battery cover to separate from the housing.

3. The electronic device as described in claim 2, wherein each of the at least one resisting element comprises an elastic portion and a resisting portion, when the battery cover is secured to the housing, the at least one elastic portion is compressed, and when the latching elements disengage from the hook portions, the at least one elastic portion rebounds to resist the at least one resisting portion, thus the at least one resisting portion pushes the battery cover to separate from the housing.

4. The electronic device as described in claim 3, wherein the number of the at least one resisting element is two, the housing comprises a first shell and a second shell secured to the first shell, the second shell defines a receiving space for receiving the battery cover, a bottom surface of the receiving space defines a pair of first through holes, a pair of receiving posts opposite to the receiving space is formed on the second shell, each of the receiving posts defines a second through hole, each of the second through holes communicates with one of the first through holes, the elastic portions and a part of the resisting portion of one of the resisting elements are received in one of the second through holes, and the other part of each of the resisting portion is received in one of the first through holes.

5. The electronic device as described in claim 4, wherein each of the resisting portions comprises a first cylinder and a second cylinder, each of the elastic portions resists one of the first cylinders, the diameter of each of the first cylinders is less than each of the second through holes and larger than that of each of the first through holes, and the diameter of the each of the second cylinders is less than that of each of the first through holes.

6. The electronic device as described in claim 5, wherein the bottom surface of the receiving space defines a pair of latching holes between the first through holes, each of the hook portions passes through one of the latching holes and hooks onto one of the latching elements.

7. The electronic device as described in claim 5, wherein the magnetic element comprises two coaxial magnetic coils, the magnetic element comprises a connecting portion connecting the magnetic coils, and the connecting portion is electrically connected to the circuit board.

8. The electronic device as described in claim 7, wherein a limiting space is formed on the magnetic element between the magnetic coils, a receiving portion between the receiving posts is formed on the second shell for receiving the magnetic element, the receiving portion comprises a limiting portion and an opening, the limiting portion passes through the limiting space and the connecting portion is placed in the opening.
