Description

The automatic positioning equipment of pivot device

Technical field

The utility model relates to a kind of automatic positioning equipment of pivot device, refers to especially prevent that to reach its screen from colliding the function of pedestal when folding, and can effectively save the automatic positioning equipment that its member is formed on a kind of pivot device that is applied to mobile computer.

Background technology

Common mobile computer mainly has LCD screen at present, and one inside be provided with the pedestal of various computer hardware, and this mobile computer is that reduced volume is carried to make things convenient for the user, normally between LCD screen and pedestal, pivot device is set, the function that makes its LCD screen directly on pedestal, open and to fold, and for preventing the pivotal action of LCD screen because of pivot device, and when closure and pedestal produce the bump situation, so have relevant dealer to be provided with automatic positioning equipment in addition, use making LCD screen cause damaging in closing Shi Buhui collision pedestal in pivot device.

As Fig. 5 and shown in Figure 6, pivot device 30 for known tool automatic positioning equipment, this pivot device 30 includes the bonding pad 31 that can be fixedly arranged on LCD screen, the stator 32 that can be fixedly arranged on pedestal, and one provide aforementioned bonding pad 31 and stator to establish on it for 32 groups, makes its pivot that can be pivoted relative to each other to each other 33.Wherein, automatic positioning equipment 40 is arranged on the pivot 33, and be positioned at stator 32 1 sides relatively, it mainly is made up of stop block 41, locating piece 42 and the elastic parts 43 that can be sheathed in regular turn on the pivot 33, this stop block 41 is fixedly arranged on stator 32 sides, and stop block 41 and locating piece 42 are provided with the protuberance 411 and the recess 412 that can engage mutually, and stop block 41 protuberances 411 cooperate LCD screen in open on the pedestal and closure after angle and the design that is distributed in distance.

By this, this automatic positioning equipment 40 can utilize nut to be locked on the pivot 33, when the user carries out folding of LCD screen on pedestal, its bonding pad 31 that is incorporated into LCD screen can drive pivot 33 and locating piece 42 pivots simultaneously, and force the recess 421 of locating piece 42 and the protuberance 411 of stop block 41 to break away from mutual fastening state, when pivoting, screen folds when being parastate with pedestal, stop block 41 and locating piece 42 can form the engaging location once more by the pushing and pressing of elastic parts 43, LCD screen is folded form the location when being parastate, so can be because of folding bump mutually with pedestal.

But the pivot device 30 of aforementioned known tool automatic positioning equipment, its automatic positioning equipment 40 can not collide pedestal for making LCD screen when the closure, so members such as the stop block 41 of tool engaging function and locating piece 42 must be set simultaneously, can reach and make screen fold the effect of Shi Buhui collision pedestal, right this measure not only causes the assembled component of this pivot device 30 to increase, and then improves its manufacturing cost, and also can cause the loaded down with trivial details of pivot device 30 number of assembling steps, and do not meet economic benefit generally speaking.

Therefore, for improving the shortcoming of aforementioned known tool automatic positioning equipment pivot device, the design people develops a kind of automatic positioning equipment of pivot device.
