BACKGROUND OF THE INVENTION

1. Technical Field

The invention relates to the technical field of accessories of mobile phone shells and tablet personal computers, in particular to a simple kickstand for electronic devices.

2. Description of Related Art

As is commonly known, electronic devices such as mobile phones and tablet personal computers have become common products in people's daily life with the continuous development of science and technology. Users use mobile phones or tablet personal computers generally by holding them by hand, and may feel fatigue after holding the heavy electronic devices for a long time. To allow users to use electronic devices for a long time without feeling tired, corresponding kickstands are used to support the electronic devices at a proper angle.

At present, there are two types of kickstands: external kickstands and kickstands integrated on the shell of electronic devices. When the external kickstand is used, an electronic device is directly placed on the external kickstand to be supported by the kickstand; however, such a kickstand has to be carried by users all the time. Compared with the external kickstand, the kickstand integrated on the shell of electronic devices does not need to be separately carried by users and can be used to support electronic devices at any time, thus being popular with most users.

However, existing integrated kickstands are designed as follows: a receiving groove is formed in the shell of electronic devices, and the kickstand is hinged to the receiving groove as a single piece, so a corresponding hinge port has to be formed in the receiving groove of the electronic devices, which inevitably increases the machining costs and manufacturing difficulties. In addition, the existing kickstands are provided with a damping shaft, for which a hinge gasket has to be additionally disposed on a plate of the kickstands to ensure the connecting stability, thus increasing the thickness of the plate of the kickstands and increasing the depth of the receiving groove, bringing difficulties to the overall design because the thickness of the shell of the electronic devices is limited.

BRIEF SUMMARY OF THE INVENTION

The objective of the invention is to overcome the defects of the prior art by providing a simple kickstand for electronic devices.

To fulfill the above objective, the invention adopts the following technical solution:

A simple kickstand for electronic devices comprises a base plate, a support plate, and a hinge pin, wherein the base plate and the support plate are located at the same end and are provided with lugs, pin cavities are formed in the lugs of the base plate and the support plate, one pair of symmetrical end faces of the hinge pin are arc faces, the other pair of symmetrical end faces of the hinge pin are planes, the hinge pin sequentially penetrates into the pin cavities of the support plate and the base plate, inner wall faces of the shaft cavities fit the end faces of the hinge pin, and the base plate is detachably assembled on a back shell of an electronic device.

Preferably, a back side of the base plate is coated with a 3M adhesive, and the base plate is attached to the back shell of the electronic device with the 3M adhesive.

Preferably, the base plate is provided with at least one lug, the support plate is provided with at least two lugs, and the lug of the base plate is disposed between the lugs of the support plates.

Preferably, an arc notch is formed in an end, opposite to the lugs, of the support plate.

Preferably, the base plate and the support plate are both metal plates, and the hinge pin is a metal hinge pin.

Preferably, electroplated coatings are disposed on surfaces of the base plate and the support plate.

Preferably, an electroplating suspension hole is formed in the base plate or the support plate.

Preferably, conical heads are disposed at two ends of the hinge pin.

By adoption of the above solution, the base plate and the support plate constitute the kickstand, and the base plate is used as a component hinged and connected to the support plate, such that it is no longer necessary to dispose a corresponding hinge part on the shell of the electronic device. The arc faces and planes of the hinge pin fit the inner wall faces of the pin cavities, so that a damping effect can be realized during the rotating process, and the base plate and the support plate can be restored instantly or be unfolded at a fixed angle after being rotated to a certain angle, and can be self-locked after being restored. In addition, through the combination of the pin cavities formed in the self-locked lugs, and the hinge pin, hinge gaskets can be eliminated, such that the thickness of the base plate and the support plate is greatly decreased in design.

The embodiments of the invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the invention may be implemented in different manners defined and covered by the claims.

As shown inFIG. 1toFIG. 5, this embodiment provides a simple kickstand for electronic devices. The simple kickstand for electronic devices comprises a base plate1, a support plate2, and a hinge pin3, wherein the base plate1and the support plate2are located at the same end and are provided with lugs4, pin cavities5are formed in the lugs4of the base plate1and the support plate2, one pair of symmetrical end faces of the hinge pin3are arc faces6, the other pair of symmetrical end faces of the hinge pin3are planes7, the hinge pin3sequentially penetrates into the pin cavities5of the support plate2and the base plate1, inner wall faces of the pin cavities5fit the end faces of the hinge pin3, and the base plate1is detachably assembled on a back shell of an electronic device.

In this embodiment, the base plate1and the support plate2constitute the kickstand, and the base plate1is used as a component hinged and connected to the support plate2, so that it is no longer necessary to dispose a corresponding hinge part on the shell of the electronic device. When the simple kickstand is used, the base plate1is assembled on the back shell of the electronic device, and the support plate2is used as a support bar. When the simple kickstand is not used, the support plate2and the base plate1are folded together; and when used to support the electronic device, the support plate2is unfolded. The base plate1and the support plate2are unfolded or unfolded by rotation. In this embodiment, corresponding structures are designed to realize the rotation of the base plate1and the support plate2. Specifically, the lugs4are formed on the base plate1and the support plate2, the pin cavities5are formed in the lugs4, and the hinge pin3penetrates into the pin cavities5. When clamped in the pin cavities5, the hinge pin3will be elastically squeezed by the pin cavities5, a damping effect is realized by the clamping force of the pin cavities5to the hinge pin3, and the base plate1and the support plate2are able to rotate under the elastic force. In addition, the arc faces6and planes7of the hinge pin3fit the inner wall faces of the pin cavities5, such that the angle can be fixed during the rotating process, that is, a damping effect is realized. When the base plate1and the support plate2need to be restored after being rotating to be staggered with each other, the base plate1and the support plate2can be restored instantly by means of the elastic force of the pin cavities5, and can be self-locked after being restored. Moreover, the lugs4and pin cavities5in this embodiment may also be formed by curling, and the specific structure is shown inFIG. 4andFIG. 5.

Further, in this embodiment, to detachably assemble the base plate1on the back shell of the electronic device, the back side of the base plate1is coated with a 3M adhesive, and the base plate1is attached to the back shell of the electronic device with the 3M adhesive. In this way, the base plate1can be assembled on the back shell of the electronic device in an attached manner and can be detached from the back shell of the electronic device.
