Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an electronic device in which a back cover is easy to open. [Prior Art] [0002] Currently, most consumer electronic devices include a detachable back cover to facilitate replacement of the battery, SIM card or SD card by the user. If the designer is unreasonable in designing the back cover engaging mechanism or the boxing mechanism of the electronic device, the user needs to take a long time and a great deal of effort to disassemble the back cover of the electronic device, and the process of directly covering or disassembling the back cover There is a possibility that the engaging mechanism or the cover mechanism of the back cover of the electronic device may be damaged. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide an electronic device that is simple in structure and easy to disassemble/cover. An electronic device includes a body, a groove formed on the body, and a back cover for closing the groove, wherein the back cover is provided with a knob, a slider, and a first portion connected to the knob and the slider a resilient member, a latching post is protruded from a sidewall of the slider; an opening is formed at one end of the recess, and a latching hole is formed in the inner wall of the recess adjacent to the opening, and a slideway is connected to the latching hole The slide rail extends to the surface of the body adjacent to the groove, and the latching post of the slider is movably received in the latching hole; the second elastic member is fixedly disposed on the inner wall of the recess opposite to the opening, and the second elastic The piece abuts against the first end of the back cover. [0005] Compared with the prior art, the card slot is driven to disengage from the card slot hole on the electronic device body by rotating the knob on the back cover, and the second elastic member presses the first end of the back cover to make the card position The column slides out automatically along the slideway, so that the back cover automatically rises from the body groove, so that the back cover of the electronic device is automatically opened 1013325705-0 09910806^^AQ1{)1 S 3 f / Total 17 pages 13765591 | 101 years 08^77曰@1£胃^] Kai, easy to operate. [Embodiment] [0007] [0008] The present invention will be further described in detail below with reference to the accompanying drawings. Referring to Fig. 1, the electronic device 1 for facilitating opening of the back cover includes a body 2, a recess 40 formed in the body 20, and a back cover 3 for closing the recess 40. The electronic device 10 can be a mobile phone, an e-reader, a personal digital assistant (PDA), or a personal laptop. Referring to FIG. 2 together, the rear cover 30 has a flat shape on which a knob 33 is disposed. The recess 40 is formed at the end of the recess 20 of the body 20, and the second elastic member 8 is fixedly disposed on the inner wall of the recess 40 opposite to the opening 50, and the side wall 1〇1 of the recess 40 adjacent to the opening 5 is provided. Slide 7〇. In the present embodiment, the second elastic member 80 is provided with two springs. 3 and FIG. 4, the rear cover 30 includes a first end portion 31 and a second end portion 32 opposite to each other. The second elastic member 80 abuts against the first end portion 31 of the rear cover 30. The two end portions 32 are bent to form a cover wall 381, and the inner surface of the cover wall 381 is convexly provided with a convex rail 3081. An end wall 34 is formed on one side adjacent to the second end portion 32, and a through hole 383 is formed in the end wall 34. The rear cover 30 is further provided with a guiding rod 389, and the end of the guiding rod 389 is fixed to the inner side of the end wall 34. [0010] The rear cover 30 further defines a through hole 36, and the knob 33 is rotatably disposed in the through hole 36 and one end thereof passes through the through hole 36. Extending to the inside of the rear cover 30. The rear cover 30 is further provided with a first elastic member 35 and two sliders 37. One end of the first elastic member 35 is fixed to the circumference of the knob 33 and the other end thereof is fixed to the two sliders 37. The two sliders 37 are oppositely disposed on opposite sides of the knob 33. One of the sliders 37 is slidably disposed in the through hole 383 of the end wall 34, and the other slider 37 is slidably disposed on the guide rod 389. 09910806#单号A0101第4页/ Total 17 pages 1013325705-0 1376591 On August 27, 101, the nuclear replacement was replaced by the other end. A latch post 39 is protruded from a side of the two sliders 37 opposite to each other. In the present embodiment, the first elastic member 35 is two springs and is fixedly coupled to the two sliders 37 which are disposed on opposite sides of the knob 33, respectively. [0011] Referring also to FIGS. 5 and 6, the ramp 70 includes a chute 71 and a trailing end 72, and the chute 71 is located on the surface of the body 2 adjacent to the recess 4. A latching hole 90 is formed in the side wall 101 and communicates with the chute 70 through the chute end 72. The slide 70 extends to the surface of the body 2 adjacent to the groove 40. The latch post 39 of the slider 37 is movably received in the latch hole 90. The depth of the latch hole 90 is greater than the end of the slide. The depth of 72 prevents the card post 39 from automatically sliding out along the chute 70 through the chute end 72. In the present embodiment, the two side walls 1 〇 1 of the recess 40 are provided with a four-slide 70 and a four-clamp hole 9 〇, wherein the slide 70 is substantially curved. [0012] The body 2 of the opening 50 is further provided with a sliding slot 60 so that the convex rail 3081 of the rear cover 30 is accommodated in the sliding slot 6 and slides along the sliding slot 6 . In addition, referring to FIG. 2 and FIG. 3, in the present embodiment, the side wall 101 adjacent to the chute 60 is provided with a first magnet piece 382, and the inner surface of the end wall 34 is provided with a second magnet that is attracted to the side wall 101. The sheet 392 is such that the back cover 30 can automatically slide along the chute 60 under the action of a magnetic force. [0013] The process of opening the back cover: Referring to FIG. 1, first, the knob 33 is rotated, and the knob 33 drives the first elastic member 35 to move, so that a spring of the first elastic member 35 pulls a slider 37 along the guide rod 389. The knob 33 is close, and the other spring of the first elastic member 35 pulls the other slider 37 out of the through hole 383 and approaches the knob 33 so that the card post 39 disposed on the two sliders 37 is latched from the body 20. The hole 90 is removed. Since the second elastic member 80 presses the first end portion 31' of the rear cover 30, the card post 39 slides from the chute end 72 along the chute 70 to 09910806^^^^ A 〇 101 page 5 / total 1.7 pages 1013325705-0 1376591 On August 27, 101, the 100-way chute 71 was replaced and slipped out from the chute 71, so that the back cover 3〇 was automatically raised from the groove 40. [0014] [0016] [0020] [0020] As shown in FIG. 7, since the first magnet piece 382 on the side wall 101 and the second magnet piece 392 of the end wall 34 attract each other, the second end portion 32 is convex. The rail 3081 slides along the chute 60 such that the rear cover 30 slides away from the recess 40 to expose the recess 40. The process of closing the back cover: first, the rear cover 30 is pushed along the chute 60 to slide over the recess 40, and then the rear cover 30 is pressed so that the latch post 39 slides from the chute 71 along the chute 70 to the chute end 72. At the same time, the first end portion 31 of the rear cover 30 presses the second elastic member 80 to elastically deform, and finally continues to press the rear cover 3 0 'the first elastic member 35 pushes the slider 3 7 to move the card. The post 39 is snapped into the bayonet aperture 90 such that the back cover 3 is closed to the recess 4. Those skilled in the art will recognize that the above embodiments are only used for (d) the present invention, and not The invention is intended to be limited to the scope of the invention as set forth in the appended claims.
