Embodiment
For the purpose and the advantage that make inventing type is clearer, the present invention is described in further detail below in conjunction with accompanying drawing 1 to 12 and embodiment.
As depicted in figs. 1 and 2, the embodiment of the invention one disclosed slide drive module comprises first sliding unit 10 and second sliding unit 20, be slidingly connected between described first sliding unit 10 and second sliding unit 20, also comprise the gathering sill 11 that is arranged on first sliding unit 10, and be arranged at the driver element 30 between first sliding unit 10 and second sliding unit 20.Described driver element 30 comprises driver element first end 31 that rotates and be slidingly connected in the gathering sill 11, driver element second end 32 that is rotationally connected with second sliding unit 20.Described slide drive module also comprises the damping block 40 that is arranged on second sliding unit 20, and described damping block 40 has concave curved surface 41, and described driver element first end 31 can slide on this concave curved surface 41.
Concrete, described first sliding unit 10 and second sliding unit 20 are slidingly connected by the guide rail 21,22 of both sides, are respectively arranged with the guide pin bushing 210 and 220 that improves lubrification, reduces wear in the described guide rail 21,22.
Concrete, as Fig. 1 and shown in Figure 5, described driver element first end 31 is riveted on by pivot structure 9 and realizes in the gathering sill 11 rotating and sliding motion, and described pivot structure 9 comprises that riveted joint sheet 93, rivet 91 and rotating shaft 92 constitute.
Described gathering sill 11 adapts with driver element 30 first motions of end 31 on concave curved surface 41, that is to say gathering sill 11 in the horizontal direction and the projector distance on the vertical direction when equaling driver element first end 31 respectively and moving on concave curved surface 41, driver element 30 elastic deformations are at the level and the vertical projector distance of both direction.
In order to make the damping block have stable damping, described damping block cooperates with hole on second sliding unit 20 by at least one the hot melt post 411 on the damping block 31, by hot melt damping block 40 is installed on second sliding unit 20.
Described damping block has projection 412 near a side of second sliding unit, can reduce damping block 40 upper surface scratches first sliding unit 10 lower surfaces in the sliding process.
As shown in Figure 3, further described concave curved surface 41 comprises introduction segment AB, and an end and the vertical direction of described introduction segment AB are tangent, and curvature is by diminishing greatly gradually, the introduction segment AB other end extends main paragraph BC, and the curvature of main paragraph BC is identical with introduction segment other end curvature and remain unchanged.In conjunction with Fig. 2, Fig. 3, shown in Fig. 7 to 9, when driver element 30 has just contacted with the concave curved surface introduction segment AB segmental arc of damping block 40, this moment, driver element first end 31 still was close to an end of gathering sill 11, driver element 3 is about to enter and is subjected to damping state, when cam surface AB section is slided, driver element discharge compression can the trend that discharges when not having the damping block of trend slow, and curvature changing along with cam surface, energy discharges more and more slower, the BC section be with the installing hole 23 of driver element 3 one ends on base plate 20 are isocentric circular arc, the end face 43 of driven unit 4 is when cam surface BC end slides like this, driven unit value with joint efforts remains unchanged substantially, but it offers the carriage upper plate and reduces along the component of glide direction, carriage is done the motion that acceleration reduces at this moment under the frictional force effect, realize damping, but because the curvature of this section radian does not have variation substantially, so can give the more level and smooth feel of user.
In addition, in the process that whole damping is slided, need to guarantee that driver element can move swimmingly on concave curved surface 41, the dieback phenomenon can not occur.When this just needs to guarantee that driver element slides on concave curved surface 41, the reverse frictional force that must apply greater than 40 pairs of driver elements 30 of damping block along the component of glide direction.When should slide with concave curved surface 41 greater than driver element first end 31 in the angle of inclination of gathering sill 11 along continuous straight runs from the locking angle, if less than from the locking angle, will make that locking phenomenon appears in driver element, promptly driver element can not slide along gathering sill.Define from locking angle a herein and follow the coefficient of friction f of driver element first end 31 and gathering sill 11 relevant, its pass is tan a=f, and promptly gathering sill 11 should be greater than arctanf with respect to the inclination angle of horizontal direction.When shaping-orientation groove 11, its size be by changing driver element first end 31 driver element when damping block concave curved surface 41 slides elastic deformation level and vertically the projection of both direction adjust.
Preferably, the end of the BC section of concave curved surface has screens groove 413, has obvious card to end effect in the time of can allowing driver element stop from moving to, and embodies better feel.
Preferred described damping block is that rigid material is made, thereby described concave curved surface when work curve form is stable, helps the stable release of driver element elastic energy.
Preferably, as shown in figure 10, be respectively arranged with damping block 4 and 4 ', thereby can realize that first sliding unit all carries out damping when opening or closing relatively and slides relatively no matter be with second sliding unit at two tache motorices of slide drive module.
Further, described driver element is a kind of in stage clip, torsion spring, the snake spring.Driver element 320 is the torsion spring structure among the embodiment two as shown in figure 12.Among the embodiment three shown in Figure 13, what driver element 330 adopted is the snake spring structure.Certain described driver element does not limit to this, if can realize slip driving and with suitable can the adopting of damping block of the present invention.
The embodiment of the invention also discloses a kind of portable terminal, comprise the first relative motion main body and the second relative motion main body, and being connected in slide drive module between the described first relative motion main body and the second relative motion main body, described slide drive module is above-described slide drive module.
Subtract accelerated motion by adopting damping block structure of the present invention can realize that carriage is done in sliding process, thereby in sliding process, have the damping sense, and can play cushioning effect, reduce and impact, improve the useful life of carriage.
In sum, more than be preferred embodiment of the present invention only, be in order to help to understand the spirit and the main points of this patent, but be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
