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. A push-push type latch mechanism comprising:

a platform;

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

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.

2. The push-push latch mechanism of claim 1, wherein the damping component is a damping gear.

3. The push-push latch mechanism of claim 1, wherein the damping component is a friction wheel or a friction gear.

4. The push-push latch mechanism of claim 1, further comprising at least one spiral spring disposed on a fixed part, wherein a gap is provided between the spiral spring and the platform.

5. The push-push latch mechanism of claim 4, further comprising a substrate hanged by the at least one spiral spring.

6. The push-push latch mechanism of claim 5, wherein the substrate comprises a protrusion placed on the at least one spiral spring.

7. The push-push 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.

8. The push-push latch mechanism of claim 1, wherein the least one damping component comprises two damping components, and the damping components are disposed on opposite side of the slide hook.

9. The push-push latch mechanism of claim 8, further comprising two spiral springs disposed on a fixed part, wherein gaps are provided between the spiral springs and the platform respectively.

10. The push-push latch mechanism of claim 9, wherein the substrate is hanged by the spiral springs.

11. The push-push latch mechanism of claim 10, wherein the spiral springs are disposed on opposite sides of the substrate, and the substrate comprises two protrusions placed on the spiral springs respectively.

12. 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;

two spiral springs disposed on the electronic device, wherein gaps are provided between the spiral springs and the platform respectively; and

a substrate hanged by the spiral springs.

13. The electronic device with the push-push type latch mechanism of claim 12, wherein the spiral springs are disposed on opposite sides of the substrate, and the substrate comprises two protrusions placed on the spiral springs respectively.

14. The electronic device with the push-push type latch mechanism of claim 12, wherein the damping components are damping gears.

15. The electronic device with the push-push type latch mechanism of claim 12, wherein the damping components are friction wheels or friction gears.

16. The electronic device with the push-push type latch mechanism of claim 12, wherein an end of the spring is fixed on the platform, and another end of the spring is connected to the slide hook.

17. The electronic device with the push-push type latch mechanism of claim 12, further comprises an assembly disposed on the substrate, wherein the assembly comprises a groove disposed on a side surface of the assembly.

18. The electronic device with the push-push type latch mechanism of claim 17, wherein the assembly is a mobile phone.

19. The electronic device with the push-push type latch mechanism of claim 18, wherein the electronic device is a notebook computer.

20. 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;
