Embodiment
For making those skilled in the art better understand the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, embodiment of the present utility model discloses a kind of pivot, and for connecting display end and the system end of notebook computer, this pivot comprises rotating shaft 10, gear 30 and shaft seat 20; One end of rotating shaft 10 is fixedly connected with display end, and can rotate with display end; Gear 30 is fixedly connected on the other end of rotating shaft 10, and can rotate with rotating shaft 10, so, can rotate by driven gear 30 when display end rotates; Shaft seat 20 is fixedly connected on system end, and it is also provided with the tooth bar 221 engaged with gear 30, and so, the gear 30 rotated just can relative to shaft seat 20 moving linearly on shaft seat 20 by engaging with tooth bar 221.
As Figure 2-Figure 5, notebook computer is in opening procedure, the angle of display end and system end constantly increases, display end makes clockwise rotation by rotating shaft 10 driven gear 30, gear 30 is while making clockwise rotation, and by engaging with the tooth bar 221 on shaft seat 20, the rectilinear motion away from system end also made by gear 30, thus make display end can walk around the protuberance of system end in articulated section, display end and system end can not be interfered in whole opening procedure.Notebook computer is in fastening process, the angle of display end and system end constantly reduces, display end makes counter-clockwise rotary motion by rotating shaft 10 driven gear 30, gear 30 is while making counter-clockwise rotary motion, by engaging with the tooth bar 221 on shaft seat 20, the rectilinear motion near system end also made by gear 30, finally make after notebook computer fastens completely, namely when the angle of display end and system end is 0 °, display end and system end reach minimum in the gap of articulated section, and the rectilinear motion of the close system end that gear 30 is done and notebook computer are in opening procedure, the track of the rectilinear motion away from system end that gear 30 is done is identical, therefore, in notebook computer fastening process, display end also can be walked around protuberance and can not interfere with system end.
In fact, have the notebook computer of this pivot in moving process, display end had both done the rotary motion of system for winding end, do again near or away from the rectilinear motion (i.e. translation) of system end.The reason that display end does above-mentioned motion is, the gear 30 in rotating shaft 10 has carried out engaged transmission with the tooth bar 221 on shaft seat 20.In the engaged transmission process of gear 30 and tooth bar 221, gear 30 both rotated, and did again rectilinear motion (i.e. translation).
Gear 30 can be fixedly connected with rotating shaft 10 in several ways, as adopted one-body molded mode, bonding way and welding manner etc., for improving maintenanceability and the maintainability of pivot structure of the present utility model, in a preferred embodiment of the present utility model, gear 30 and rotating shaft 10 are arranged to removably connect, particularly, rotating shaft 10 is by rotating shaft body 11 and axle 12 one or welding fabrication, gear 30 center offers a hole matched with axle 12 cross section, and gear 30 is located in this axle 12 by this borehole jack.So, gear 30 had both achieved with rotating shaft 10 and had removably connected, and can rotate again with rotating shaft 10.In the present embodiment, rotating shaft body 11 is connected with rotating shaft fixed head 80 away from one end of axle 12, and rotating shaft body 11 is fixed on display end by rotating shaft fixed head 80.
The structure of shaft seat 20 can have multiple, in a preferred embodiment of the present utility model, shaft seat 20 is the L-type structure formed by the base 21 of tabular and stand 22, base 21 is screwed on system end, above-mentioned tooth bar 221 is arranged on stand 22 towards on the side of base 21 side, and the orientation of tooth on tooth bar 221 is vertical with base 21.
The display end of notebook computer not only needs system for winding end to carry out rotating to regulate the angle opened, and after having regulated angle, need to make display end remain on this angle and free rotation does not occur, for this reason, the damping piece preventing display end from freely rotating and damping structure are set in pivot of the present utility model.Particularly, the sheathed friction disc 50 at the middle part of axle 12, the first damping slot 222 is offered in the position that stand 22 is relative with friction disc 50, friction disc 50 part stretches into the first damping slot 222, and the first damping slot 222 is arranged to its side can with the physical dimension of the contacts side surfaces of friction disc 50 so that when friction disc 50 rotates with rotating shaft 10, produce with the first damping slot 222 friction force stoping rotating shaft 10 to be rotated, namely countershaft 10 produces damping.In the present embodiment, sheathed three friction discs 50 in interval in axle 12, accordingly, stand 22 offer three the first damping slots 222.
Move towards the direction away from stand 22 in the radial direction thereof for preventing rotating shaft 10, and then cause gear 30 and tooth bar 221 to come off gear 30 cannot be engaged with tooth bar 221, in a preferred embodiment of the present utility model, pivot also comprises for limiting rotating shaft 10 in the radial direction thereof away from the rotary shaft cover 40 of stand 22 movement, this rotary shaft cover 40 is fastened on shaft seat 20 by staircase structure, and fixed by pin 90 and shaft seat 20, rotary shaft cover 40 and shaft seat 20 form the cavity of the rectangle that wears for rotating shaft 10, this rectangular cavities away from or size on stand 22 direction be less than away from or size on base 21 direction.So, rotating shaft 10 driven gear 30 and friction disc 50 away from or movement on base 21 (namely away from or near system end) direction unrestricted, away from or be restricted on stand 22 direction, therefore, this rotary shaft cover 40 can effectively prevent gear 30 and tooth bar 221 from coming off, and gear 30 is well engaged with tooth bar 221.In the present embodiment, the position that rotary shaft cover 40 is relative with friction disc 50 offers the second damping slot 41.
For improving the stability of gear 30 and tooth bar 221 engaged transmission so that notebook computer folding is more steady, in a preferred embodiment of the present utility model, sheathed two gears 30 in axle 12, and these two gears 30 lay respectively at the outside of two friction discs 50 in outside.
For damping that rotating shaft 10 produces can be adjusted so that folding notebook computer, in a preferred embodiment of the present utility model, axle 12 is also arranged with multi-disc shell fragment 60 and (in Fig. 1, has only indicated one, in fact, between adjacent two friction discs 50 and be shell fragment 60 between friction disc 50 and gear 30), the end of axle 12 is also provided with adjusting nut 70, and adjusting nut 70 is by screwing extrusion elastic 60 to adjust the contact force of the side of friction disc 50 and the first damping slot 222 and the second damping slot 41.Contact force is larger, and the friction force between friction disc 50 and damping slot is larger, and the damping that rotating shaft 10 produces is larger, otherwise damping is less.
The invention also discloses a kind of notebook computer with above-mentioned pivot.The display end of notebook is connected by this pivot with system end, and therefore, the notebook computer with this pivot by display end and the gap design of system end and the less of manufacture, can add the compactedness of laptop structure.
Above embodiment is only exemplary embodiment of the present utility model, is not used in restriction the utility model, and protection domain of the present utility model is defined by the claims.Those skilled in the art can in essence of the present utility model and protection domain, and make various amendment or equivalent replacement to the utility model, this amendment or equivalent replacement also should be considered as dropping in protection domain of the present utility model.
