Abstract
The utility model provides a kind of hinge of portable type electronic product, and it comprises axle and axle sleeve, and described axle and axle sleeve are connected one of them of two main bodys that correspondence is articulated and connected respectively; It is characterized in that described axle sleeve is for having flexible axle sleeve, is embedded brake pad in described axle sleeve, described axle is the axle that side face has camming surface, described axle by described axle sleeve banding, utilized its elasticity by described axle sleeve and with brake pad close contact.The utility model utilizes elastic shaft sleeve to the extruding of axle, when axle when rotated, the different parts contact friction block of its camming surface, make elastic shaft sleeve produce different deformation diametrically, thus the pressure that axle is applied on brake pad is different, and then produces different frictional force, achieve torsion in rotation process variant, can realize opening and closing the different operating feel in rotatable parts process, and it is little to take up room, structure is very simple.
Description
Technical field
The utility model relates to the hinge of portable type electronic product, and described portable type electronic product can be notebook computer, pad, mobile phone, gaming machine etc.
Background technique
At present, for the such as portable type electronic product such as notebook computer, pad, its thickness is more and more thinner, moreover, also more and more higher to the requirement of the opening and closing operating characteristics of the rotatable parts such as its lid, support, need more exert oneself when more easily closing when such as opening lid, or on the contrary, like this, requirements at the higher level are proposed to the structure of hinge.But slimming design means there is more restriction to hinge structure, and this often becomes again the obstacle of modified node method biggest obstacle.
Summary of the invention
The purpose of this utility model is to provide a kind of hinge of portable type electronic product, and its structure is simple, can realize operating the different operating feel in rotatable parts process.For this reason, the utility model is by the following technical solutions:
The hinge of portable type electronic product, comprises axle and axle sleeve, and described axle and axle sleeve are connected one of them of two main bodys that correspondence is articulated and connected respectively; It is characterized in that described axle sleeve is for having flexible axle sleeve, is embedded brake pad in described axle sleeve, described axle is the axle that side face has camming surface, described axle by described axle sleeve banding, utilized its elasticity by described axle sleeve and with brake pad close contact.
On the basis adopting technique scheme, the utility model also can adopt following further technological scheme:
Described axle sleeve is the open loop type axle sleeve of lateral opening.
Described axle sleeve internal surface arranges axial groove, and described brake pad is embedded in groove, and a part for described brake pad is in inside the circular arc reference line of axle sleeve internal surface.
The brake pad part surface be in inside described circular arc reference line is plane.
Owing to adopting the technical solution of the utility model, the utility model utilizes elastic shaft sleeve to the extruding of axle, when axle when rotated, the different parts contact friction block of its camming surface, makes elastic shaft sleeve produce different deformation diametrically, thus the pressure making axle be applied on brake pad is different, and then produce different frictional force, achieve torsion in rotation process variant, can realize opening and closing the different operating feel in rotatable parts process, and it is little to take up room, structure is very simple.

Fig. 3 is the demonstration graph in axle rotation process embodiment illustrated in fig. 1.
Fig. 4 is the coordinate schematic diagram of torsion generation difference in axle rotation process embodiment illustrated in fig. 1.
Fig. 5 uses the demonstration graph of pad of the present utility model in its support opening procedure.
Embodiment
With reference to accompanying drawing.The hinge of portable type electronic product provided by the utility model, comprises axle 1 and axle sleeve 2, and described axle 1 and axle sleeve 2 are connected one of them of corresponding two main bodys be articulated and connected respectively; As shown in Figure 5, the utility model hinge to be applied to the support 301 on pad, described axle sleeve 2 can be in the parts be connected with pad main body 300, and axle 1 is on the parts that are connected with support 301.
Described axle sleeve 2 is for having flexible axle sleeve, and it can adopt metal powder injection molding, and it is closely coated by axle 1 according to himself elasticity, and axle sleeve internal surface can arrange multiple tiny groove 20, for storing lubricant oil, improves wearability.Described axle sleeve is the open loop type axle sleeve of lateral opening 22 as shown in the figure.
Brake pad 3 is embedded in described axle sleeve 2, described brake pad is embedded in the groove 21 on axle sleeve internal surface, a part for described brake pad 3 is in inside the circular arc reference line of axle sleeve internal surface, and also namely this part distance apart from axle sleeve axle center of brake pad 3 is less than the radius of the circular arc reference line of axle sleeve internal surface).The brake pad part surface 30 be in inside described circular arc reference line is plane.
Described axle 1 has the axle of camming surface for side face, described axle 1 by described axle sleeve 2 banding, utilized its elasticity by described axle sleeve and with brake pad close contact.
With reference to Fig. 3,4, it is 180 degree for open angle, described camming surface is arc surface 41 and the plane 42,43 being in arc end two ends, and when opening beginning, plane 42 contacts with brake pad, now, the radius of the contact position of cam and brake pad is minimum, and the deformation that elastic shaft sleeve produces diametrically is minimum, thus the pressure that axle is applied on brake pad is minimum, frictional force is minimum, so operation is very light when opening beginning; After opening several angle, arc surface 41 contacts with brake pad, now, the radius of the contact position of cam and brake pad is maximum, and the deformation that elastic shaft sleeve produces diametrically is maximum, thus the pressure making axle be applied on brake pad is maximum, frictional force is maximum, can obtain good operating handle according to this frictional force, and once stop operating, its stiction provides enough detent force overcoming gravity, realizes the arbitrarily angled function opening stopping of hinge; When the final stage opened, plane 43 contacts with brake pad, and identical with situation during plane 42 contact friction block, now rotating operation becomes again light, and the change in torque of above operating process is shown in the curve 100 of Fig. 4.In closing process, the change of moment of torsion is just in time contrary, sees the curve 200 of Fig. 4.
