Locking device and electronic device using the same

The present invention relates to a locking device, and more particularly to a locking device for an electronic device.

The development of electronic devices is increasingly inclined to small, thin, light requirements, and its hardware structure is constantly required for easy assembly. In the case of a host, it includes a bottom case and a corresponding top case. The conventional host assembly is screwed from the bottom of the electronic device to fix the bottom case and the top case. Although this method can obtain a better locking force, it is inconvenient to lock and disassemble, and the internal units of the electronic device are inconvenient. (For example, hard disk drives, central processing units or various interface cards), the top case must be opened first. If the main unit is locked in the above manner, it will increase the inconvenience, time and labor.

In view of the above, it is necessary to provide a lock device that is easy to install and disassemble and an electronic device that uses the lock device.

A locking device for locking a first component and a second component of an electronic device housing, comprising: a locking member slidably mounted on the first component and capable of being on the first component Moving between a first position and a second position, the lock locks the first component and the second component when the lock is moved from the first position to the second position, when the lock is When the two positions are moved to the first position, the locking between the first component and the second component is released; at least one elastic positioning member is used in the The lock is resiliently positioned when the lock is moved to the second position.

An electronic device includes a first component, a second component, and a locking device for locking the first component and the second component, the locking device including at least one locking component and at least one of the locking components a mating elastic positioning member; the locking member being mounted on the first member and movable between the first position and a second position on the first member, when the locking member is moved by the first position When the second position is reached, the locking member locks the first member with the second member, and when the locking member is moved from the second position to the first position, releasing between the first member and the second member The elastic locating member is configured to elastically position the locking member when the locking member is moved to the second position.

Referring to FIG. 2 together, the host 100 includes a housing and an electronic component (not shown) such as a computer CPU housed in the housing, the housing including a first component and a second component corresponding to the first component. And a four locking device 30 that secures the first component and the second component together. In the present embodiment, the first component is the bottom case 10 of the main body 100, and includes a rectangular top wall and a side wall vertically extending from the periphery of the top wall. The second component is the top case 20 of the main body 100, which is in the form of a rectangular plate. And covering the edge of the side wall of the bottom case 10. The four locking devices 30 are respectively disposed at four corners on the lower side of the main body 100 for locking the top case 20 to the bottom case 10. It will be appreciated that the number of locking devices 30 is not limited to four.

As shown in FIG. 3 and FIG. 4 , each of the locking devices 30 includes an "I" shaped locking member 31 and two elastic positioning members 32. The elastic positioning member 32 includes an elastic member 320 and a positioning member fixed to one end of the elastic member 320. 322. In the present embodiment, the elastic member 320 is a spring, and the positioning member 322 has a spherical shape. It can be understood that in other embodiments, the shape of the positioning member 322 is not limited to being spherical.

The lock body 31 includes a first level portion 311, a second level portion 312, and a vertical portion 313 that is perpendicular to the first level portion 311 and the second level portion 312, respectively. The first level portion 311 and the second level portion 312 and the vertical portion 313 form two notches 314 and 315. The two opposite end faces of the first level portion 311 of the locking member 31 are respectively provided with grooves 316 for receiving the positioning members 322. The lock member 31 is for engaging the bottom case 10 and the top case 20 together.

The bottom portion 101 of the bottom case 10 is provided with a through hole 11 corresponding to the first level portion 311 of the locking member 31, The perforations 11 extend through the bottom case 10. The through hole 11 includes a first card plate 12 and a second card plate 13 respectively corresponding to the notches 314 and 315 of the locker 31, and the second card plate 13 has two side walls 14 connected at both ends thereof. The two side walls 14 are respectively provided with two receiving slots 141 corresponding to the two elastic members 320. One end of the two elastic members 320 is fixed in the two receiving slots 141, and the other end is fixedly connected to the two positioning members 322. The first level portion 311 is in sliding contact with the first card board 12 and the second card board 13.

The top portion 201 of the top case 20 is provided with a boss 21 corresponding to the first level portion 311 of the lock member 31. The upper surface 22 of the boss 21 protrudes from a rail 25 which is slidable at a notch 315 of the locking member 31. The first level portion 311 of the locking member 31 is slidably contacted with the upper surface 22 of the boss 21. The first card board 12 is engaged with the notch 314, and the second card board 13 and the railing 25 are engaged with the notch 315.

When assembling, the first level portion 311 of the lock 31 and the upper surface 22 of the boss 21 are correspondingly contacted, and the lock 31 can slide along the upper surface 22 of the boss 21. The first level portion 311 can pass through the railing 25 and the railing 25 can be placed at the notch 315. In addition, the second leveling portion 312 of the locking member 31 passes through the through hole 11 of the bottom case 10, and the first level portion 311 is placed on the first card board 12 and the second card board 13, and the first card board 12 and the second board 12 The card plates 13 are respectively located within the notches 314 and 315 of the fastener 31, the first card plate 12 and the second card plate 13 are approximately parallel to the railing 25, and the railing 25 is located between the second card board 13 and the vertical portion 313. At this time, the lock 31 is located at the first position on the bottom case 10. When the locking member 31 is moved in the direction of the second card plate 13, the locking member 31 is gradually brought into contact with the positioning member 322 fixed to the elastic member 320 at one end until the positioning member 322 is engaged in the recess 316 on both end faces of the locking member 31. The rail 25 stops at the vertical portion 313. At this time, the lock 31 is located at the second position on the bottom case 10. The lock member 31 secures the bottom case 10 and the top case 20 integrally (as shown in Fig. 5).

When disassembling, the locking member 31 is pushed in the opposite direction. When the positioning member 322 slides out of the groove 316, the second card 13 and the rail 25 gradually slide out of the notch 315. At this time, the lock 31 is on the bottom case 10 The second position is moved to the first position, the boss 21 is disengaged from the lock 31, and the lock 31 is separable from the top case 20. Thereby, the separation of the bottom case 10 and the top case 20 is achieved (as shown in Fig. 6).
