## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 098143445 filed in Taiwan, R.O.C. on 17 Dec. 2009, the entire contents of which are hereby incorporated by reference.
FIELD OF THE INVENTION
The present invention relates to electronic device carriers, and more particularly, to an electronic device carrier that can be removed without producing much fiction and can position the electron device at its location firmly.
BACKGROUND OF THE INVENTION
A conventional electronic device is usually placed on a carrier or usually requires a carrier, for recharging or data transmission purpose. In so doing, friction arises between the electronic device and the carrier while the electronic device is being removed from or placed on the carrier. Plenty of the conventional electronic devices are encapsulated with the protective rubber. In this regard, rubber is notorious known for its excessive friction, which not only prevents the conventional electronic device from being smoothly removed from or positioned in the carrier but also damages the edges of the electronic device or a corresponding portion of the carrier.
The prior art pertaining to reduction of aforesaid friction is disclosed in Taiwan Patent No. 571608, M264742, and 525864. Taiwan Patent No. 571608 discloses a wearproof base structure comprising an elastic structure that has a rubber pad provided on a supporting base such that when the electronic device comes into contact with the rubber pad, it will induce the rubber pad to undergo an elastic deformation after the electronic device is placed on the supporting base. The elasticity derived from deformation provides resistance to the electronic device. However, the wearproof base structure cannot reduce friction at all.
Taiwan Patent No. M264742 discloses a recharger structure, comprising a supporting platform provided thereon with a stop block for limiting the movement of a battery placed on the supporting platform and fixing the battery to the supporting platform. However, the recharger structure is not free from the excessive friction while being removed or positioned.
Taiwan Patent No. 525864 discloses a quick-assembly mobile phone recharger comprising clamping mechanisms that are designed at the sides of a casing of a mobile phone so as to clamp the mobile phone and precisely position the mobile phone in between the clamping mechanisms. However, great friction is generated between the mobile phone and the clamping mechanisms in the course of the removal or the positioning of the mobile phone.
SUMMARY OF THE INVENTION
It is an objective of the present invention to provide an electronic device carrier comprising a rolling element for rolling and thereby having point contact with an electronic device so as to efficiently reduce friction between the electronic device and a base of the electronic device carrier, so as to allow the electronic device to be smoothly removed or positioned, and it protects the electronic device and the base from damage.
Another objective of the present invention is to provide an electronic device carrier, wherein a resilient element of each of the rolling devices exerts a resilient force for driving the rolling element pivotally connected to the resilient element to tightly clamp the electronic device and position the electronic device to a receiving chamber of the electronic device carrier firmly.
Yet another objective of the present invention is to provide an electronic device carrier comprising a transmission unit whereby the data transmission between the transmission unit and the electronic device takes place.
The electronic device carrier of the present invention comprises a base and two rolling devices. The base is concavely provided with a receiving chamber. The base has two sidewalls located at two opposing ends of the receiving chamber respectively. Each of two sidewalls is concavely provided with a chamber opening facing toward the receiving chamber.
The two rolling devices each comprise a resilient element and a rolling element. The resilient element of each of the rolling devices is coupled to the base and is extended toward the chamber opening of a corresponding one of the sidewalls until the resilient element is provided with a pivotally connecting end. The resilient element of each of the rolling devices exerts a resilient force toward the receiving chamber. The rolling element of each of the rolling devices is pivotally connected to the pivotally connecting end, and is located in the chamber opening of each of the sidewalls, and each rolling element is protruded toward the receiving chamber.
When the electronic device is positioned in the receiving chamber of the base or removed from the receiving chamber of the base, the electronic device comes into contact with the rolling element of the rolling devices. Consequently, the rolling movement of the rolling element provides the point contact between the rolling element and the electronic device, thus the friction between the electronic device and the base is effectively reduced. As a result, the removal and positioning of the electronic device is smooth, and the electronic device or the base is protected from damage.
When the electronic device is positioned in the receiving chamber of the base, the resilient element of each of the rolling devices exerts a resilient force for driving the rolling element pivotally connected to the resilient element to tightly clamp the electronic device and fixing the electronic device to the receiving chamber.
In another embodiment of the present invention, the electronic device carrier comprises a base, two rolling devices, and a transmission unit. The base is concavely provided with a receiving chamber. The base has two sidewalls located at two opposing facing of the receiving chamber respectively. The sidewalls are each concavely provided with a chamber opening open to the receiving chamber.
The two rolling devices each comprise a resilient element and a rolling element. The resilient element of each of the rolling devices is coupled to the base and extends toward the chamber opening of a corresponding one of the sidewalls until the resilient element is provided with a pivotally connecting end. The resilient element of each of the rolling devices exerts a resilient force toward the receiving chamber. The rolling element of each of the rolling devices is pivotally connected to the pivotally connecting end, received in the chamber opening of each of the sidewalls, and protruding toward the receiving chamber.
The transmission unit comprises a control panel and an electrical connector electrically connected to the control panel. The control panel is internally coupled to the base. The electrical connector is coupled to the base and exposed to the receiving chamber.
Accordingly, in addition to the aforesaid effects, the electronic device carrier enables data transmission between the transmission unit and the electronic device when the electronic device is positioned in the receiving chamber of the base.
