Description
Technical field
The utility model relates to the notebook pivot structure.
Background technology
Notebook computer is small and exquisite portable, by working clan is at present praised highly.Along with the height of notebook computer function is integrated, there is the interface of many external equipments on the whole body that inevitably makes notebook computer base especially notebook base rear design.When the design of notebook computer rotation shaft, usually can the location structure of block effect be arranged to notebook rotating shaft design, thereby the maximum angle that the screen board of notebook computer is opened is about 160 °.The effect of notebook computer rotation shaft location structure is to remind the user to maximum angle, and the interface at the notebook computer base rear may be connected to the external equipment connecting plug, does not continue opening action.The damage that can reduce the notebook screen board to collide with the external equipment connecting plug like this and cause.
But when reality is used, tend to take place some accidents, notebook rotating shaft location structure is damaged.Such as in the notebook computer open mode, certain reason suddenly, external force presses the notebook screen board to make it cross maximum open angle suddenly, causes the damage of notebook rotating shaft location structure, makes the block disabler of location structure.Thereby make notebook screen board shell may often bump to the external equipment plug, thereby notebook computer is caused damage, influence the normal use of notebook computer, shorten the serviceable life of notebook computer greatly.
The utility model pivot structure can overcome above-mentioned defective.
The utility model content
The purpose of this utility model is to provide a kind of notebook rotating shaft that overcomes bad location structure of the violent crushing of external force.
The utility model discloses a kind of notebook rotating shaft, the spacer that comprises upper bracket, rotates with respect to upper bracket, wherein, described spacer side is provided with elastic arm, the elastic arm end is provided with the elasticity extended end, and the position of matching with the elasticity extended end in the described upper bracket is provided with the positioning convex that elasticity extended end gear is provided.
Further, wherein, described positioning convex is provided with first lead-in chamfered and second lead-in chamfered relatively, and the position of first, second lead-in chamfered of the corresponding positioning convex of described elasticity extended end is respectively equipped with the 3rd lead-in chamfered and the 4th lead-in chamfered.
Further, the described axostylus axostyle that is inserted in spacer and upper bracket successively that comprises, wherein, described axostylus axostyle is provided with clearance position with the position that positioning convex and elasticity extended end match.
The utility model pivot structure improves the location structure of existing rotating shaft, overcome because the violent suddenly shortcoming of pressing screen board to cause notebook rotating shaft location structure to damage of external force, thereby ensured the block function of location structure, guaranteed the serviceable life of notebook computer effectively.

Embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.
The utility model pivot structure is to improve on existing pivot structure basis.As shown in Figure 1 and Figure 2, existing notebook computer rotation shaft comprises lower carriage 1, axostylus axostyle 2, spacer 3, upper bracket 4, cam set 5, dish-like shell fragment group 6, pad 7 and securing member 8.As shown in Figure 3, an outstanding positioning convex 41 is arranged on 3 contacted of upper bracket 4 and the spacers, spacer 3 designs have the extending part 31 of symmetry, the block function in the time of can realizing the rotating shaft folding.As shown in Figure 4, when the notebook screen board opens to 160 ° of maximum angles, positioning convex 41 on the upper bracket 4 fits tightly with the extending part 31 on the spacer 3, by the extending part 31 on the positioning convex 41 block spacers of upper bracket 4, limit the maximum angle that screen board is opened, realize the positioning function of rotating shaft.As shown in Figure 5, suddenly press when screen board suffers external force, when the screen board open angle surpasses maximum open angle, the positioning convex 41 on the upper bracket 4 will be interfered with extending part 31 extruding on the spacer 3, thereby upper bracket positioning convex 41 caused to scrape decreases p, thereby makes notebook computer lose the block function.
This novel pivot structure improves at this situation.To shown in Figure 9, the utility model rotating shaft comprises axostylus axostyle 20, spacer 30 and upper bracket 40 as Fig. 6, and the positioning convex 410 on the upper bracket 40 has first lead-in chamfered 411 by mould impact briquetting manufacturing; Design has an elastic arm 32 on the spacer 30, spacer 30 uses the spring steel material manufacturing, so elastic arm 32 has suitable elasticity, the butt design that elastic arm 32 connects the spacer main body has a circular hole 321, the end of elastic arm 32 has an outstanding elasticity extended end 322, is processed with the 3rd lead-in chamfered 3221 on the elasticity extended end 322 on the elastic arm 32; End design at the axle bed 21 of axostylus axostyle 2 has a clearance position 211, and the degree of depth of this clearance position 211 and length are as the criterion with the elasticity extended end 322 that can be contained on the elastic arm 32 in the motion process.
Extremely shown in Figure 12 as Figure 10, when the notebook screen board opens to maximum angle (as 160 °), the utility model rotating shaft is coming in contact on first lead-in chamfered 411 of the positioning convex 410 of upper bracket 40 and on the 3rd lead-in chamfered 3221 of the elasticity extended end 322 on the elastic arm 32 of spacer 30, realizes the block function.When the notebook screen board is subjected to that external force is suddenly violent presses, the extruding slippage takes place on the 3rd lead-in chamfered 3221 on the elasticity extended end 322 on the elastic arm 32 of first lead-in chamfered 411 on the positioning convex 410 of upper bracket 40 and spacer 03, the elastic arm 32 of spacer 30 is offset, during elastic arm 32 skew of spacer 30, just 211 li of the clearance position of the axle bed 21 that is contained in axostylus axostyle 20.The positioning convex 410 of upper bracket 40 can be crossed the elasticity extended end 322 on the elastic arm 32 of spacer 30 like this, elasticity extended end 322 shift state on the elastic arm 32 of spacer 30 are recovered former state, and can not cause damage to the positioning convex 410 and the spacer 30 of upper bracket 40.Turn back rotating shaft with certain power equally again, the 4th lead-in chamfered 3222 of the elasticity extended end 322 of second lead-in chamfered 412 of the positioning convex 410 of upper bracket 40 and elastic arm 32 ends of spacer 30 contacts, continuation turns back rotating shaft, the positioning convex 410 of upper bracket 40 will push elasticity extended end 322, make it to be offset, when positioning convex 410 strode across extension 322 on the elastic arm 32 of spacer 30, this rotating shaft returned to normal flip angle scope.Rotating shaft has just been avoided damaging because of the rotating shaft that external force presses the notebook screen board to cause suddenly like this, has guaranteed the block function of rotating shaft, has prolonged the serviceable life of rotating shaft.
In sum, more than be preferred embodiment of the present utility model 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 domain of the present utility model.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
