Detailed Description
The present invention will be described in detail below with reference to the drawings and detailed description to enable those skilled in the art to better understand the technical scheme of the present invention.
As shown in fig. 3 and 4, an embodiment of the present invention discloses a hinge assembly for connecting a display end 20 and a system end 10 of an electronic device so that the display end 20 can be rotated with respect to the system end 10, thereby enabling to change an opening angle of the display end 20. The hinge assembly includes a hinge 40 formed by sequentially hinge-jointing a plurality of hinge shafts, and the hinge 40 has the characteristic of being repeatedly bendable without damage due to the sequential hinge-jointing of the hinge shafts, and has a structure and a use form similar to a watch chain. The hinge 40 is used to connect the display end 20 and the system end 10 such that the display end 20 can be opened by any angle within a maximum range due to the bending characteristic of the hinge 40. The key of the embodiment of the present invention is that the relationship between the length of the hinge 40 connected to the display end 20 and the system end 10 and the opening angle of the display end 20 is configured as follows: the length of the hinge 40 between the access display end 20 and the system end 10 increases as the opening angle of the display end 20 increases.
Configuring the access length of the hinge 40 in the above relationship with the opening angle of the display end 20 can solve the problem of wrinkling of the cover layer 30 integrally covering the display end 20 and the system end 10 when the display end 20 is opened.
Before describing how the hinge assembly of the embodiment of the present invention solves the problem of wrinkling of the cover layer 30, the reason why the electronic device applied to the prior art is wrinkled when the display end 20 is opened will be first analyzed. The rotation axis assembly of the prior art for connecting the display end 20 and the system end 10 makes the rotation center of the display end 20 unchanged, and when the opening angle of the display end 20 is 0 ° (i.e. when the display end 20 is closed), the cover layer 30 is on the same plane (i.e. the cover layer 30 is not bent); when the opening angle of the display end 20 increases, the bending angle of the cover layer 30 (the bending position of the cover layer 30 corresponds to the position where the display end 20 is connected to the system end 10) starts to increase, and when a plate member having a certain thickness (the cover layer 30 may be regarded as a plate member) is bent according to the principle of material mechanics, the bending radius becomes smaller as the bending angle increases, and thus the bending radius of the cover layer 30 becomes smaller. When the bending radius of the cover layer 30 is smaller than the minimum bending radius thereof (which depends on the thickness of the cover layer 30 under a certain material), protons (which may be regarded as particles forming the cover layer 30 with a certain binding force including repulsive force and attractive force therebetween) which are farther away from the rotation axis assembly in the thickness direction of the cover layer 30 at the bending position have a tendency to squeeze each other, and the protons resist such a tendency that the portion of the cover layer 30 away from the rotation axis assembly resists bending, which causes the cover layer 30 to separate from the display end 20 and the system end 10 at the bending position, thereby wrinkling. From the above, the reason for the wrinkling of the cover layer 30 is that: the bending radius of the cover layer 30 becomes smaller as the opening angle of the display end 20 increases, and the bending angle of the cover layer 30 becomes smaller, resulting in wrinkling.
Based on the above analysis, the length of the hinge 40 between the display end 20 and the system end 10 according to the embodiment of the present invention increases with the opening angle of the display end 20, and this relationship can effectively prevent the bending radius of the cover layer 30 from becoming smaller with the opening angle of the display end 20. The reason is that: when the opening angle of the display end 20 increases, the length of the hinge 40 is also increased, at this time, the display end 20 may be considered to be a plate having a certain thickness, the hinge 40 forms an outer bending radius of the plate, and the cover layer 30 may be considered to form an inner bending radius of the plate as a whole, when the length of the hinge 40 is increased, the outer bending radius formed by the hinge 40 at least does not decrease with the increase of the opening angle of the display end 20, and further, the inner bending radius also does not decrease with the increase of the opening angle of the display end 20, that is, during the rotation of the display end 20 in the opening range, the overall bending radius of the cover layer 30 does not decrease to the minimum bending radius, so that the cover layer 30 is not wrinkled.
The structure capable of realizing the above-mentioned relationship between the access length of the hinge 40 and the opening angle of the display end 20 may be various, for example, the two ends of the hinge 40 are movably connected with the display end 20 and the system end 10, i.e., the two ends of the hinge 40 are respectively moved in the length direction of the hinge 40 relative to the display end 20 and the system end 10. As shown in fig. 3 and 4, in a preferred embodiment of the present invention, one end of the hinge 40 is restricted and the other end is provided in a movable manner with respect to the display end 20, specifically, the display end 20 is provided with a fixing member 60 near the system end 10, one end of the hinge 40 is fixed at the system end 10 near the display end 20, the other end of the hinge 40 is provided with a telescopic member 50, and the fixing member 60 is formed with a sliding groove, and the telescopic member 50 is at least partially extended into the sliding groove. In this way, when the opening angle of the display end 20 is continuously increased, the hinge 40 forms a pulling force for pulling the expansion member 50 to maintain the bending angle unchanged, and the pulling force makes the expansion member 50 continuously slide out of the chute, so as to increase the access length of the hinge 40, further ensure that the bending radius of the hinge 40 is kept constant, and prevent the cover layer 30 from wrinkling.
It should be noted that: the extension of the extension 50 into the chute should be such that the end of the extension 50 does not come out of the chute when the display end 20 is opened a maximum angle.
In order to make the bending form of the hinge 40 more stable and the overall bending more approximate to a circular arc, in a preferred embodiment of the present invention, as shown in fig. 6, a layer of auxiliary board 70 is covered on the outer side of the hinge 40 (the outer side of the hinge 40 refers to the side of the hinge 40 near the system end 10) along the length direction of the hinge 40, two ends of the auxiliary board 70 are respectively connected to the display end 20 and the system end 10, and the relationship between the length of the auxiliary board 70 connected between the display end 20 and the system end 10 and the opening angle of the display end 20 is configured as follows: the access length increases with increasing opening angle of the display end 20. The reason why the relationship between the access length of the auxiliary board 70 and the opening angle of the display end 20 is the same as that of the hinge 40 is not described herein.
When the display end 20 is opened, the bent shape of the auxiliary plate 70 is closer to an arc, and when the display end 20 is opened, the applied force is mostly carried by the auxiliary plate 70, so that the shape of the hinge 40 is more regular and closer to an arc.
In order to achieve the above relationship between the access length of the auxiliary board 70 and the opening angle of the display end 20, as shown in fig. 8, and in combination with fig. 6, one end of the auxiliary board 70 is fixedly connected to the system end 10, the other end is provided with an oblong hole 71, and a screw 81 is inserted through the oblong hole 71 and is in threaded connection with the fixing member 60 so that the auxiliary board 70 can slide relative to the fixing member 60. In this way, as the opening angle of the display end 20 increases, the access length of the auxiliary board 70 increases.
The following should be noted: the purpose of the screws 81 is to adjust the tension required for sliding the auxiliary plate 70 with respect to the fixing member 60 so that the insertion length of the hinge 40 coincides with the amount of change in the insertion length of the auxiliary plate 70.
In order to prevent the auxiliary plate 70 from being deformed plastically without being restored due to the excessively small bending radius of the auxiliary plate 70, the auxiliary plate 70 is made of spring steel having a large elastic modulus, and the thickness of the auxiliary plate 70 is not more than one fifth of the minimum bending radius thereof. This allows the auxiliary plate 70 to be bent at a smaller radius without plastic deformation.
The structure and size of the hinge shafts constituting the hinge 40 may be varied, and in a preferred embodiment of the present invention, the hinge shafts constituting the hinge 40 include fixed hinge shafts 41 provided at both ends of the hinge 40 and movable hinge shafts 42 provided between the fixed hinge shafts 41, and the fixed hinge shafts 41 have a diameter larger than that of the movable hinge shafts 42, wherein one fixed hinge shaft 41 is fixed to the system end 10 and the other fixed hinge shaft 41 is coupled to the telescopic member 50. The diameter of the fixed hinge shaft 41 is larger than that of the movable hinge shaft 42, so that the bending of the auxiliary plate 70 is smoother.
In order to limit the amount of change in the access length of the hinge 40, that is, the amount of expansion of the expansion piece 50 when the opening angle of the display end 20 is changed from 0 ° to the maximum angle, in this embodiment, the fixing piece 60 is a rectangular block fixed to the display end 20 by a set screw, and as shown in fig. 7, the slide groove includes a guide portion 62 and a housing portion 61 penetrating the guide portion 62, the expansion piece 50 is a telescopic rod, the head of the telescopic rod is formed with a stopper 51, the stopper 51 is located in the housing portion 61 and slides along the length direction of the telescopic rod together with the telescopic rod when the opening angle of the display end 20 is changed, and the dimension of the housing portion 61 in the length direction of the telescopic rod is set to be equal to the maximum amount of change in the access length of the hinge. In this way, the telescopic rod can be freely extended and contracted, and the length of the telescopic rod beyond the length required for extending the hinge 40 to be connected can be limited.
The embodiment of the invention also discloses an electronic device, such as a notebook computer, which comprises a system end 10 and a display end 20, wherein a covering layer 30 is paved on the display end 20 and the system end 10, and the system end 10 and the display end 20 are connected through the rotating shaft assembly. Because the electronic equipment is provided with the rotating shaft assembly, the cover layer 30 cannot be wrinkled when the display end 20 is opened, so that the dustproof effect of the electronic equipment is improved, and the appearance is attractive.
The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this invention will occur to those skilled in the art, and are intended to be within the spirit and scope of the invention.
