Electronic device having sliding assembly
An electronic device having a sliding assembly is described. A cantilever having a slide-proof pad is disposed on a bottom surface of a casing, and a sliding assembly corresponding to the cantilever is disposed in the casing. When the casing is pressed, the sliding assembly extends outside the slide-proof pad through an elastic displacement of the cantilever, such that the sliding assembly supports the casing to a higher position, and the casing slides on and contacts with a plane through the sliding assembly; alternatively, the sliding assembly retracts into the slide-proof pad, such that the slide-proof pad contacts with the plane, and the casing does not slide freely on the plane through interference contact of the slide-proof pad.
1. An electronic device having a sliding assembly, enabling the electronic device to have a sliding contact or an interference contact with a plane, comprising:
a casing, having a bottom surface, wherein at least one groove is disposed on the bottom surface, a cantilever that may have a swing displacement is corresponding to the groove, the cantilever has a through hole, and a slide-proof pad is disposed on the cantilever, the cantilever has a blocked position where the slide-proof pad contacts with the plane, and an evading position where the slide-proof pad retracts into the casing; and
a sliding assembly, disposed in the casing, and corresponding to the cantilever, wherein the sliding assembly comprises:
a cylinder, fixed to the casing; and
a movable member, movably disposed on the cylinder and corresponding to the through hole, wherein the movable member moves to a first position, a second position, and a third position relative to the cylinder; when the movable member is at the first position, the cantilever makes the slide-proof pad remain at the blocked position; when the movable member is at the second position, the cantilever makes the slide-proof pad remain at the evading position; when the movable member is at the third position, the movable member supports the casing higher, such that the slide-proof pad leaves the plane, and the movable member and the plane have the sliding contact.
2. The electronic device having a sliding assembly according to claim 1 , wherein the casing further comprises a rolling component, the rolling component is disposed on the bottom surface, and is freely rotatable relative to the bottom surface, and the rolling component and the groove are located on two opposite sides of the bottom surface.
3. The electronic device having a sliding assembly according to claim 1 , wherein the bottom surface further comprises a cut groove, the cut groove is disposed around the cantilever, and the cantilever has the swing displacement through the cut groove.
4. The electronic device having a sliding assembly according to claim 1 , wherein the sliding assembly further comprises a telescopic component, and the telescopic component further comprises:
a circulating guide groove, disposed on an internal side wall of the cylinder;
a guide rod, having one end connected to the movable member, and the other end movably located in the circulating guide groove to have a reciprocal displacement; and
an elastic element, normally pushing the movable member towards the second position.
5. The electronic device having a sliding assembly according to claim 1 , wherein the movable member is made of a material having a low friction coefficient, a side of the movable member has a contact surface, and the contact surface forms a point contact on the plane.
6. The electronic device having a sliding assembly according to claim 1 , wherein the movable member further comprises a ball, and the ball is disposed on a bottom of the movable member and is freely rotatable relative to the bottom, and forms a point contact on the plane.
7. The electronic device having a sliding assembly according to claim 1 , wherein the slide-proof pad protrudes from the bottom surface of the casing.
8. The electronic device having a sliding assembly according to claim 1 , wherein the slide-proof pad is made of a material having a high friction coefficient.
