Abstract
The utility model discloses a pivotal-rotating device used for connecting an upper cover body and a lower cover body of a notebook computer. The utility model comprises a base and a rotating part connected with the base, wherein, the base comprises a positioning part arranged at one end of the base and a sleeve barrel arranged at the other end corresponding to one end of the base; the rotating part comprises a rotating shaft matched with the sleeve barrel and a connecting part connected with the rotating shaft, wherein, an opening formed by the butt joint of the sleeve barrel and the rotating part is provided with a chamfer angle; the rotating shaft of the rotating part is provided with a plurality of grooves used for storing the lubricating oil; when the upper cover body is rotated, the utility model can effectively prevent the lubricating oil from overflowing from a gap between a rotating shaft and the sleeve barrel by the arrangement.
Description
The relevant a kind of pivoting device of the utility model refers in particular to a kind of pivoting device that is used on the notebook computer.
The prior art relevant with the utility model can be with reference to U.S. Patent application the 5th, 632,066 and 5,896, No. 622 grades and TaiWan, China patented claim the 85219836th, 85218533 and No. 83212590 etc., see also the synoptic diagram that Figure 1 shows that existing pivoting device, this pivoting device 5 comprises the pedestal 50 that is provided with through hole 51, deck 56, sleeve 52, pad 53 and connecting portion 54, wherein this connecting portion 54 is provided with the rotating shaft 55 that matches with pad 53 and sleeve 52 at its front end, after the assembling, connecting portion 54 rotating shafts 55 are passed pad 53 and are contained in the sleeve 52, and the catch 57 of being located at rotating shaft 55 ends connects with pad 53.In addition,, reduce the wearing and tearing of rotating shaft 55 and sleeve 52, add lubricating oil at this pivoting device 5 usually for stablizing torsion.But, when rotating shaft is rotated, the lubricating oil that catch 57 and pad are 53 is squeezed, because of the gap between pad and rotating shaft very little and between pad and catch no any guiding device, lubricating oil be easy to from this pivoting device excessive and pollute other the device, this can cause the normal performance of other apparatus function or bring the user inconvenience.
The utility model purpose is to provide a kind of being used for also can effectively prevent the pivoting device that lubricating oil is excessive on the notebook computer.
The utility model pivoting device comprises pedestal and the rotation section that links to each other with pedestal, wherein this pedestal comprises that the location division of being located at an end reaches in the sleeve of the relative other end, wherein this rotation section comprises rotating shaft that matches with sleeve and the connecting portion that links to each other with rotating shaft, this sleeve is provided with a chamfering at the inner wall edge of itself and docking site, rotation section, by such arrangement, when preventing effectively that when the notebook computer upper cover body rotates the gap location between the lubricating oil axis of rotation and sleeve is excessive.
Prior art relatively, the utility model with sleeve lining that rotating shaft matches on offer a chamfering, thereby this chamfering cooperates the slit of sleeve can and overflow outside unlikely the lubricating oil guiding when the notebook computer upper cover body rotate, thereby the function of torsion is stablized in realization.
Below in conjunction with diagram and embodiment the utility model is further described.
Fig. 1 is the three-dimensional exploded view of existing pivoting device.
Fig. 2 is the three-dimensional exploded view of the utility model pivoting device.
Fig. 3 is the three-dimensional combination figure of the utility model pivoting device.
Fig. 4 is the cut-open view of Fig. 3 along the A-A line.
See also Fig. 2 to shown in Figure 4, the utility model pivoting device 1 comprises pedestal 15 and the rotation section 11 that is connected with this pedestal 15, wherein pedestal 15 comprises tabular location division 151 and the sleeve 152 that is connected with location division 151, and wherein this location division 151 is provided with several pilot holes that runs through this tabular location division 151 153.In addition, be provided with sleeve 152 in these location division 151 1 ends, this sleeve 152 is ring-type by sheet metal bending and is made into integration with location division 151, is provided with the slit 156 of flowing out for lubricating oil in its lower end, and is provided with the chamfering 154 that flows out for lubricating oil in sleeve 152 inwalls 157 relative with rotation section 11.
Wherein rotation section 11 comprises rotating shaft 110 that matches with the sleeve 152 of pedestal 15 and the connecting portion 111 that is connected with rotating shaft 110, wherein this rotating shaft 110 is provided with several grooves 113 that stores lubricating oil, and is provided with the fillet 114 that plays a transition role in these rotating shaft 110 front ends.Connecting portion 111 is provided with up and down two recesses 116,115 in its back-end so that connecting portion therebetween is tabular, and is provided with several through holes 117 in this tabular connecting portion 111.
When assembling finishes, this moment, connecting portion 111 rotating shafts 110 were contained in the sleeve 152, sleeve 152 sidewalls 155 connect with connecting portion 111 roofs 112, after adding lubricating oil, when rotating shaft 110 rotations, the lubricating oil that sleeve 152 and connecting portion are 111 then can and flow in the sleeve 152 through chamfering 154 guiding through extruding, after 156 flow in the space that stores lubricating oil (not shown) through the slit again, thereby prevent that effectively lubricating oil is excessive.
