Specific implementation mode

Below in conjunction with the accompanying drawings, the present invention is described in detail.

In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not For limiting the present invention.

As shown in figures 1-13, a kind of headrest fitting device, including holder 6, driving part 9, pedestal 1 and sleeve 5, pedestal 1 On the frame 6 with the setting of sleeve 5, pedestal 1 is used to support headrest, and driving part 9 drives opening for close/separate sleeve of pedestal 15 Mouthful, sleeve 5 is more than the opening of the other end, respectively large port 513 and portlet 512 close to the opening of 1 one end of pedestal, that is, The openings of sizes at 5 both ends of sleeve is different, and one end is big and the other end is small, pillowcase is placed in the portlet 512 of sleeve 5 as a result, so Pillow 41 is inserted by large port 513 afterwards, and firmly pushes away pillow 41 to portlet 512, pillow 41 is compressed in inner cavity 53, and There is portlet 512 to go out, hence into pillowcase, in entire assembling process, manually finger need not be used to squeeze pillow 41, It only needs pillowcase being placed on portlet 512 and pin, while pushing away pillow 41 and suit work can be completed, assembly effect can be improved Rate, while labor intensity is reduced, further, it is possible to the damage caused by 41 surface layer of pillow during avoiding worker from squeezing pillow 41, The risk that stabilizer blade 42 of resting the head on during pillowcase can also be avoided to be placed on pillow 41 damages worker's abdomen；In addition, using driving Dynamic component 9 drives pedestal 1 to push pillow 41 to enter sleeve 5, is pushed compared to artificial, it is strong that this programme further reduced labour Degree, can further increase efficiency.

Specifically, the opening area of portlet 512 is less than the maximum secting area of headrest pillow 41, to which pillow 41 is across small It can be automatically compressed in two steps so big to 512 opening area of portlet when port 512, and pillow 41 of resting the head on can pass through portlet 512, the opening area of large port 513 is more than the sectional area of headrest 41 head end of pillow, to allow pillow 41 to can extend into big end In mouth 513, the opening area of portlet 512 is less than the opening area of pillowcase, and just pillowcase can be placed in portlet 512.

More specifically, it is provided with the limiting section for placing stabilizer blade 42 on pedestal 1, enables the headrest being placed on pedestal 1 Sleeve 5 is smoothly pushed by pedestal 1, included angle A≤3 ° between 61 line 59 of 61 pillow axis of axis, 61 line 419 and 61 quill of axis are such as schemed 12, it so, it is possible to avoid manually pushing 61 pillow axis of axis, 61 line 419 and 61 quill of axis, 61 line 59 when pillow 41 enters sleeve 5 The too big caused headrest surface layer in drift angle scratches, and the risk that headrest surface layer scratches can be reduced, simultaneously as using the promotion of pedestal 1 Artificial promotion pillow 41 is driven, labor intensity can be reduced and improves efficiency of assembling.Preferably, it is admitted to sleeve 5 in pillow 41 During, 61 pillow axis of axis, 61 line 419 is parallel with 61 quill of axis, 61 line 59, and is smaller than equal to 2cm, so as to It enough avoids pillow 41 excessive with 5 lateral run-out of sleeve and causes 41 sleeve of pillow, 5 inner wall local friction excessive, it can be further 41 surface layer of pillow is protected, the risk scratched is reduced.

5 inner wall of sleeve is shiny surface, so, it is possible that 41 surface layer of pillow is avoided to be scratched by 5 inner wall of sleeve, specifically, sleeve 5 Inner wall is smooth surface or plane 511, and more specifically, 5 inner cavity 53 of sleeve is by gradual on large port 513 to 512 direction of portlet Become smaller, so as to the pillow 41 that gradually reduces, further decreases the risk for scratching 41 surface layer of pillow.

Further, inner cavity 53 is truncated rectangular pyramids shape, and to which 53 side of inner cavity is plane 511, and 5 inner cavity 53 of sleeve is Gradual diminution, the risk that can reduce by 41 surface layer of scratch pillow are compared further, since using the inner cavity 53 of truncated rectangular pyramids shape In using inner cavities 53 such as ellipse or circular cross-sections, processing cost is lower, more reliable and more stable.

Pillow 41 is not truncated rectangular pyramids shape, and section is also entirely rectangle, but by the rectangle after fillet, therefore, When pillow 41 is placed in sleeve 5 and is compressed, the pillow 41 and cylinder inboard wall discontinuity of the attachment of the rib of close truncated rectangular pyramids, The case where there are stress mutations be easy to cause at the stress mutation and loses surface layer close to the tearing of 41 surface layer of pillow of rib, therefore, In order to reduce the risk happened, seamlessly transitted between 5 adjacent two inner wall of sleeve, that is, the rib of truncated rectangular pyramids uses circular arc Or other modes for seamlessly transitting, it so, it is possible to tear close to 41 surface layer of pillow of rib caused by avoiding the occurrence of stress mutation.

Certainly, in order to avoid being torn close to 41 surface layer of pillow of rib caused by stress mutation, other schemes can also be used, For example, 5 inner cavity of sleeve, 53 cross section profile is similar to pillow profile 49, that is to say, that 5 inner cavity of sleeve, 53 cross section profile is pillow wheel What wide 49 equal proportions zoomed in or out, pillow profile 49 is the vertical view profile in horizontal plane 511 when pillow 41 is placed vertically, such as Shown in Fig. 7 A and 7B, it so, it is possible to ensure that pillow 41 is not much different in the bulbs of pressure of 5 inner cavity 53 of sleeve everywhere as possible, to It can ensure that the frictional force that pillow 41 moves is not much different, headrest surface layer caused by capable of avoiding frictional force difference larger as possible is torn It splits.

Sleeve 5 can be that integral type manufactures to be formed, as shown in Figure 3A, but since both ends open laugh is different and inner cavity 53 be the design of size gradation formula, therefore difficulty of processing is larger, for this purpose, modular sleeve 5 may be used, for example, such as Fig. 4-6 Shown, sleeve 5 includes first half-shell 51 and the second half-shell 52, and first half-shell 51 and the second half-shell 52 are both provided with groove portion 54, the One half-shell 51 and the second half-shell 52 cooperatively form sleeve 5, and two groove portions 54 cooperatively form inner cavity 53, and thereby, it is possible to reduce processing Cost, also, the volume of inner cavity 53 can also be adjusted, as the distance between first half-shell 51 and the second half-shell 52 change, set Cylinder 5 inner cavity 53 volume constantly changes, and large port 513 and the opening area of portlet 512 be also with variation, so as to root The distance between first half-shell 51 and the second half-shell 52 are adjusted according to the size of headrest size, pillow 41 is enable to pass through sleeve 5 enter pillowcase, so as to avoid causing 41 surface layer of pillow to scratch because 5 inner cavity 53 of sleeve is too small.

Specifically, three kinds of modes may be used in the cooperation of first half-shell 51 and the second half-shell 52：

1, simple in structure as shown in figure 4, the both ends of the surface of the both ends of the surface of first half-shell 51 and the second half-shell 52 dock to form sleeve 5；

2, above-mentioned first way will appear when needing to expand 53 area of inner cavity between first half-shell 51 and the second half-shell 52 Gap, after pillow 41 fills in sleeve 5, pillow 41 understands some sponge and comes up from gap after being squeezed, to be easy The part come up is scratched, therefore, the case where appearance in order to avoid first way, the both ends of first half-shell 51 stretch into In the groove portion 54 of two half-shells 52, and medial surface of the lateral surface at 51 both ends of first half-shell respectively at 52 both ends of the second half-shell is formed Plane-plane contact coordinates, as shown in figure 5, the part of the cooperation of first half-shell 51 and the second half-shell 52 is plane 511, to, When needing to expand 53 volume of inner cavity, it is only necessary to pull open the distance between first half-shell 51 and the second half-shell 52, can permit Perhaps while variation 53 volume of inner cavity is to avoid damage 41 surface layer of pillow, additionally it is possible to it is further avoid the occurrence of gap and caused by 41 superficial lesions of pillow, simultaneously as be plane-plane contact cooperation, therefore when adjusting 53 volume of inner cavity, first half-shell 51 or the 54 opening size of groove portion of two half-shells 52 can remain unchanged, and will not reduce inner cavity 53 between first half-shell 51 and the second half-shell 52 Occur gap when volume, can further avoid gap occur and caused by 41 superficial lesions of pillow.

3, it is different from the above-mentioned second way, another way can also be used, as shown in fig. 6, the one of first half-shell 51 End is stretched into the groove portion 54 of the second half-shell 52, and is engaged with the medial surface forming face face of the second half-shell 52, first half-shell 51 The medial surface of the other end and the lateral surface forming face face of the second half-shell 52 are engaged, to need to expand 53 volume of inner cavity When, it is only necessary to pull open the distance between first half-shell 51 and the second half-shell 52, can allow change 53 volume of inner cavity with While avoiding damage to 41 surface layer of pillow, additionally it is possible to it is further avoid the occurrence of gap and caused by 41 superficial lesions of pillow, When adjusting 53 volume of inner cavity, 54 opening size of groove portion of first half-shell 51 or the second half-shell 52 can remain unchanged, compared to injustice Capable situation gap will not occur between first half-shell 51 and the second half-shell 52 when reducing 53 volume of inner cavity, can be further Avoid the occurrence of gap and caused by 41 superficial lesions of pillow.

Such as Fig. 2, headrest fitting device further includes the connector 8 being fixedly connected with first half-shell 51 or the second half-shell 52, even It is provided with the first screw hole 81 on fitting 8, the second screw hole 31 coordinated with the first screw hole 81, the first screw hole 81 are provided on holder 6 And/or second screw hole 31 be bar shaped screw hole 31, pass through the first screw hole 81 and the second screw hole 31 that connector 8 is detachable by bolt Fixation on the frame 6, so, it is possible effectively to adjust the distance between first half-shell 51 and the second half-shell 52, so as to adjust set 5 inner cavity of cylinder, 53 volume, conveniently can adjust out suitable distance according to the size of pillow 41, avoid 41 surface layer quilt of pillow It scratches.

Be different from it is above-mentioned fixed 51 or second half-shell 52 of first half-shell is gone by the way of bar shaped screw hole 31, can also use Other modes, such as such as Fig. 1, fitting device of resting the head on further includes regulating member 7 and is fixed with first half-shell 51 or the second half-shell 52 The connector 8 of connection, connector 8 are slidably arranged on holder 6, and axis 61 is provided on holder 6, are provided on connector 8 and axis 61 hole 21 of axis of 61 cooperations, regulating member 7 is connect with connector 8 and drive connection part 8 is slided along axis 61, passes through adjusting as a result, 7 drive connection part 8 of component moves, and to drive first half-shell 51 or the second half-shell 52 to move, and then adjusts 51 He of first half-shell The distance between second half-shell 52,5 inner cavity of adjustment sleeve, 53 volume, can conveniently be adjusted out according to the size of pillow 41 Suitable distance avoids 41 surface layer of pillow from being scratched.61 hole 21 of axis on connector 8 and between on axis 61 coordinate, it is fixed to have The effect that position is oriented to, makes first half-shell 51 or the second half-shell 52 that can only be slided along the direction of axis 61.

Specifically, regulating member 7 includes the regulating member 9 of hydraulic-driven or gas-powered, that is, using hydraulic cylinder or 9 drive connection part 8 of the driving parts such as cylinder includes gear driving or screw rod driven driving part 9 compared to using, is not in Joint gap present in gear driving or screw drive, can make control more accurate, can be easier to control.
