Abstract

A push-push type latch mechanism is disclosed, which includes a platform, a slide hook with an incline disposed on the platform, a spring disposed on the platform and connected to the slide hook, and at least one damping component disposed on the platform and touching the slide hook. An electronic device with the push-push type latch mechanism is also disclosed.

Claims

1. An electronic device with a push-push type latch mechanism, the electronic device comprising:

a platform disposed in the electronic device;

a slide hook disposed on the platform and comprising an incline;

a spring disposed on the platform and connected to the slide hook;

two damping components disposed on opposite sides of the slide hook and touching the slide hook for reducing the speed of the slide hook by the friction force between the damping components and the slide hook;

two spiral springs, each spiral spring having a fixed end fixed on the electronic device, wherein gaps are provided between the fixed ends of the spiral springs and the platform respectively; and

a substrate for supporting an assembly, the spiral springs being disposed on opposite sides of the substrate, the substrate comprising two protrusions placed on the spiral springs respectively, whereby the substrate touches and pushes the incline of the slide hook for sliding the slide hook outwardly as the substrate is pushed in a pressing direction, and the assembly is coupled to the slide hook when the slide hook returns, and the substrate touches and pushes the incline of the slide hook again for sliding the slide hook outwardly to release the assembly, such that the substrate is moved upwardly and downwardly in a stroke defined by the gaps,

wherein the spiral springs are elongated in the pressing direction and in the respective gaps when the substrate is pressed in the pressing direction.

2. The electronic device with the push-push type latch mechanism of claim 1, wherein the damping components are damping gears.

3. The electronic device with the push-push type latch mechanism of claim 1, wherein the damping components are friction wheels or friction gears.

4. The electronic device with the push-push type latch mechanism of claim 1, wherein an end of the spring is fixed on the platform, and another end of the spring is connected to the slide hook.

5. The electronic device with the push-push type latch mechanism of claim 1, wherein the assembly comprises a groove for being coupled to the slide hook, the groove being disposed on a side surface of the assembly.

6. The electronic device with the push-push type latch mechanism of claim 5, wherein the assembly is a mobile phone.

7. The electronic device with the push-push type latch mechanism of claim 6, wherein the electronic device is a notebook computer.

9. The electronic device with the push-push type latch mechanism of claim 1, wherein the gap consists of a press stroke and a buffer stroke.

8. An electronic device with a push-push type latch mechanism, the electronic device comprising:

a platform disposed in the electronic device;

a first slide hook disposed on the platform and comprises an incline;

a second slide hook disposed on the platform and comprises an incline;

a spring disposed on the platform, wherein an end of the spring is connected to the first slide hook, and another end of the spring is connected to the second slide hook;

a first damping component disposed on the platform, wherein the first damping component is disposed at a side of the first slide hook and touches the first slide hook for reducing the speed of the first slide hook by the friction force between the first damping component and the first slide hook;

a second damping component disposed on the platform, wherein the second damping component is disposed on a side of the second slide hook and touches the second slide hook for reducing the speed of the second slide hook by the friction force between the second damping component and the second slide hook;

two spiral springs, each spiral spring having a fixed end fixed on the electronic device, wherein gaps are provided between the spiral springs and the platform respectively; and

a substrate for supporting an assembly, the spiral springs being disposed on opposite sides of the substrate, the substrate comprising two protrusions placed on the spiral springs respectively, whereby the substrate touches and pushes the inclines for sliding the first and second slide hooks outwardly as the substrate is pressed in a pressing direction, and the assembly is coupled to the first and second slide hooks when the first and second slide hooks returns, and the substrate touches and pushes the inclines again for sliding the first and second slide hooks outwardly to release the assembly, such that the substrate is moved upwardly and downwardly in a stroke defined by the gaps,

wherein the spiral springs are elongated in the pressing direction and in the respective gaps when the substrate is pressed in the pressing direction.

10. The electronic device with the push-push type latch mechanism of claim 8, wherein the gap consists of a press stroke and a buffer stroke.
