Description

Electronic equipment

The present invention relates to an electronic device, and more particularly to a slide type electronic device.

Existing slide-type electronic devices, such as mobile phones, typically include a body and a cover that is slidably mounted to the body. The body and the cover are substantially rectangular parallelepiped. The two long edges of the body are provided with two elongated sliders. Two long grooves are provided on the two long edges of the cover. The recess is for receiving a slider, and the slider is slidable within the recess such that the cover is slidable relative to the body.

However, in the process of using the above electronic device, it is found that when the cover body slides relative to the body, a large sliding friction force is generated between the cover body and the body, and the user or the cover body is used after a period of use. The surface in contact with the slider is subject to wear, which affects the fit between the cover and the body.

In view of this, it is necessary to provide an electronic device that reduces the wear of the surface of the cover.

An electronic device includes a body and a cover body slidably mounted on the body. The cover body is provided with a sliding slot. The body is provided with a fixing portion that is slidably engaged with the sliding slot. The fixing portion is provided with a fixing hole on the body. There is further provided a roller rotatably fitted in the fixing hole, and the body is in contact with the sliding groove of the cover body through the roller, thereby slidingly fixing the cover body to the body.

The body of the electronic device is in contact with the cover body through a roller, thereby converting the sliding friction force into a rolling friction force and reducing the wear degree of the surface of the cover body.

Figure 6 is a cross-sectional view taken along line VI-VI of the electronic device of Figure 2.

Referring to FIGS. 1 and 2, the electronic device 100 includes a body 10 and a cover 20 slidably mounted on the body 10.

Referring to FIGS. 3 and 4, the body 10 has a substantially rectangular shape with two fixing portions 13 provided thereon. The two fixing portions 13 are symmetrically disposed on the main body 10, and extend from opposite end edges of the two long edges of the body 10. The two fixing portions 13 are elongated structures in which the portions 131 are recessed downward, and fixing holes 133 are respectively formed at both ends (see FIG. 6). Two hooks 135 are respectively disposed on opposite sides of each fixing hole 133.

Two rollers 15 are also disposed on each of the fixing portions 13. The roller 15 is rotatably disposed in the fixing hole 133 of the fixing portion 13. A rotating shaft 151 is protruded from each of the two ends of the roller 15 , and the rotating shaft 151 is slidably inserted between the two hooks 135 to be fixed on the fixing portion 13 . The diameter of the roller 15 is larger than the thickness of the fixing portion 13 so that the roller 15 can be exposed to both sides of the fixing portion 13 through the fixing hole 133.

Referring to FIG. 5 at the same time, the cover 20 is slidably covered on the body 10. The cover 20 is provided with components such as a display screen, a circuit board, and a cable (not shown). The cover 20 includes a bottom plate 21 and a cover plate 23 engageable with the bottom plate 21.

The bottom plate 21 has a flat shape, and opposite edges thereof are bent toward each other to form two elongated sliding grooves 211 arranged in parallel. The sliding slots 211 are respectively configured to receive the two fixing portions 13 . The rollers 15 are exposed on both sides of the fixing portion 13 and are in contact with the wall surface surrounding the sliding groove 211, thereby preventing the fixing portion 13 from coming into contact with the wall surface surrounding the sliding groove 211, and reducing the contact area between the body 10 and the cover body 20. In addition, since the roller 15 is rotatable relative to the fixed portion 13, when the cover 20 slides relative to the body 10, the roller 15 can be rotated under the force of the frictional force of the cover 20 acting on the roller 15, thereby closing the cover The sliding friction between the body 20 and the body 10 is converted into rolling friction, which reduces the degree of wear of the contact surface between the cover 20 and the body 10. A plurality of positioning holes 213 are further disposed on the bottom plate 21.

The cover plate 23 is provided with a plurality of buckles 231. The plurality of buckles 231 are in one-to-one correspondence with the positions of the plurality of positioning holes 213, and are respectively mounted on the plurality of positioning holes 213, thereby engaging the cover plate 23 with the bottom plate 21 on.
