Detailed Description

Hereinafter, embodiments of the connecting device of the present invention will be described with reference to the accompanying drawings.

The examples described herein are specific embodiments of the present invention, are intended to be illustrative and exemplary in nature, and are not to be construed as limiting the scope of the invention. In addition to the embodiments described herein, those skilled in the art will be able to employ other technical solutions which are obvious based on the disclosure of the claims and the specification of the present application, and these technical solutions include technical solutions which make any obvious replacement or modification for the embodiments described herein.

The drawings in the present specification are schematic views to assist in explaining the concept of the present invention, and schematically show the shapes of respective portions and their mutual relationships. It should be noted that the drawings are not necessarily drawn to the same scale in order to clearly illustrate the structures of the various elements of the embodiments of the invention. Like reference numerals are used to denote like parts. Further, when the description is made with reference to the drawings, directional words such as "upper", "lower", "front", "rear", and the like are employed for convenience of description, and they do not constitute specific limitations on the structure of the features.

Referring to fig. 1 to 11, the electronic apparatus of the present invention having the support assembly of the first embodiment will be described first.

Fig. 3 is an external perspective view of an electronic device according to an embodiment of the present invention, and fig. 4 is a partially enlarged perspective sectional view of fig. 3. The electronic device comprises a first body 1, a second body 2 and a connecting device 3 for rotatably connecting the first body 1 and the second body 2, wherein a pressing plate 4 is used for fixing the connecting device 3 on the first body 1 and the second body 2 respectively. In this embodiment, the first body 1 and the second body 2 may be embodied as a display side for displaying target contents and a system side for operating the electronic device, respectively.

As shown in fig. 4, the connecting device 3 includes a first covering member 5, a second covering member 6, and a support member 7 as the first embodiment connected between inner side walls of the first covering member 5 and the second covering member 6. The support member 7 appears as a cylinder when uncompressed, as shown in fig. 8 when the enrobing mechanism 3 is in a 180 degree extended state. The connecting device 3 also comprises a turning mechanism 8, not shown in fig. 4, it being noted that the turning mechanism 8 is shown in fig. 9, 11, 12 and 18.

The rotation mechanism 8 in the connection device 3 of the present invention may take any prior art configuration. The rotating mechanism 8 may have one or more rotating axes in the axial direction, or in the lateral direction of the electronic device, and the rotating mechanism 8 having multiple rotating axes which may be parallel may be formed in a shape of a strip in the overall appearance. In the drawings, the rotation mechanism 8 embodies a rotation shaft, colloquially referred to by the applicant as a "watch chain shaft", which is generally lath-like in appearance, as shown in figures 9, 11, 12 and 18. Since the overall appearance of the rotating mechanism 8 is in the form of a strip, the first and second covers 5, 6 covering the outside of the rotating mechanism 8 each have a planar surface area, the greater the likelihood of creasing or buckling of the compressed covers when the rotating mechanism 8 is bent.

The rotating shaft is shown as 2 sections in fig. 9, 12 and 18, and is shown as 5 sections in fig. 11, please note that the number of the sections included in the rotating shaft is only schematically shown in the drawings, and can be determined according to design requirements in actual implementation, and may be a natural number such as 1, 3, 4, 6, 7, 8 … …, and the like. In this context, the structure of the rotating mechanism 8 is not explained in detail, and the structure of the prior art is adopted.

Fig. 5 is a perspective view showing a coating mechanism including a first coating member and a second coating member in a folded state according to an embodiment of the present invention. Fig. 6 is an enlarged perspective partial cross-sectional view of fig. 5 showing the support assembly 7, and the first and second cover members 5 and 6 are also clearly seen in fig. 6.

Referring again to fig. 3, 4, 9 and 11, the rotating mechanism 8 is fixedly connected to the first body 1 and the second body 2 through its connecting ends arranged in the lateral direction of the electronic apparatus, and the pressing plate 4 is fixed to the first body 1 and the second body 2 through the through holes of the pressing plate 4 and the first covering member 5 and the second covering member 6 by fastening means such as screws. In the illustrated embodiment, these through holes are also arranged in the lateral direction of the electronic device.

Fig. 7, 8, 9 and 10 further illustrate the structure and positional relationship of the support assembly 7. When the wrapping is not compressed and stretched, i.e. when neither the first wrapping 5 nor the second wrapping 6 is compressed, the support member 7 appears as a cylinder when uncompressed, as schematically shown in fig. 8.

Conversely, when the cladding is compressed and stretched, i.e. both the first and second cladding 5, 6 are bent, for example when the cladding mechanism 3 is in the folded state shown in fig. 7 (i.e. the first and second bodies 1, 2 are in the folded state, respectively), one cladding is stretched and the other cladding is compressed. The stretched wrapping apparently does not crease or wrinkle, but in the prior art the compressed wrapping may crease or wrinkle. In fig. 7, the first covering member 5 is stretched and the second covering member 6 is compressed at the bending portion, and the support member 7 is connected to the inner side walls of the first covering member 5 and the second covering member 6 at least at the bending portion, so that the second covering member 6 is under the tensile force of the support member 7 when being compressed, and the second covering member 6 is not easily creased or wrinkled at the bending portion, thereby being beneficial to being flexibly bent during the rotation operation of the rotating mechanism 8 and preventing the covering mechanism 3 from being creased or wrinkled during the rotation operation of the rotating mechanism 8.

As shown in fig. 7, when the coating mechanism 3 is bent, one end of the support member 7 located in the tension coating member is also radially expanded in tension, and the other end located in the compression coating member is radially compressed and contracted in the compression direction.

With further reference to fig. 9 and 10, the support assemblies 7 are schematically arranged in 4 rows along the curved part of the wrapping mechanism 3 and are grouped into three groups corresponding to the structure of the rotating mechanism 8, the longitudinal and transverse distances between the support assemblies 7 being set to the dimensions d1 and d2, respectively. It should be noted, however, that this arrangement is merely illustrative and that the grouping and arrangement of the support members 7 is arranged according to the actual design requirements so as to prevent the coating mechanism 3 from being creased or wrinkled. That is, the number and arrangement of the supporting members 7 can be changed according to the actual design requirement, for example, the number and arrangement can be 1, 2, 5, 6, 7 rows, etc., and the distance between the pillars (including the longitudinal distance and the transverse distance) can be different according to the material and the hardness of the supporting members 7, even the supporting members 7 can be distributed in such a way that the longitudinal distance and the transverse distance are not equal, and the supporting members can be not in a straight line, i.e., staggered.

It is specifically noted that, although fig. 9 does not show that the support members 7 are distributed at positions corresponding to one coupling, the support members 7 may actually be distributed at positions corresponding to one coupling, that is, the support members 7 may be disposed to pass through the rotating device 8, and the passing positions may be positions around the rotating device, a gap in the middle of the rotating device, or through holes particularly provided in the rotating device 8 for passing the support members 7.

The connecting device of the present invention having the support assembly 7' of the second embodiment is explained with reference to fig. 12 to 16.

Fig. 12 is a schematic view showing the internal structure of the connecting device in a deployed state with one covering removed, and fig. 13 is a schematic cross-sectional view showing the positions of the support members 7' in fig. 12 and their interrelationships. Fig. 15 is a plan sectional view of the covering mechanism at 180 degree folding showing the state of the support assembly 7' at this time, and fig. 16 is a plan sectional view of the covering mechanism shown in fig. 15 at the unfolded state. Fig. 14 shows a perspective cross-sectional view of fig. 5 in order to more clearly express the shape and positional relationship of the support member 7'.

As shown in perspective in fig. 12, the supporting member 7' of the second embodiment is also connected between the inner side walls of the two wrapping members at the bending portion of the wrapping mechanism, which is different from the cylindrical supporting member 7 of the first embodiment: the support member 7' of the second embodiment is in the shape of a long strip, the longitudinal direction of which is along the longitudinal direction of the electronic apparatus. In particular, in the figures, the support member 7' can be seen as oblong, i.e. with both ends being curved and the cross-section between the ends being rectangular. Of course, the shape of the long strip of the support member 7' is not limited to the shape shown in the figures, and a person skilled in the art may design different shapes of the long strip according to actual needs, for example, the shape may be a rectangular shape with chamfers at both ends, or even without chamfers, or the shape may be corrugated in the longitudinal direction.

The technical effect and design concept of the support member 7' is practically the same as that of the support member 7, but it is structurally different. Therefore, the design concept of the support assembly 7 can be applied to the support assembly 7 'in a completely similar manner, so that the description of the support assembly 7' can refer to the above description of the support assembly 7, and only the following two points are explained below.

As shown in fig. 15 and 16, only one support member 7' exists in the plan views of fig. 15 and 16, since a plurality of support members may no longer be provided in the longitudinal direction of the electronic apparatus. In fig. 15, the first wrapping member 5 is stretched and the second wrapping member 6 is compressed at the bending portion, and since the support member 7 'is connected to the inner side walls of the first wrapping member 5 and the second wrapping member 6 at least at the bending portion, the second wrapping member 6 is not easily creased or wrinkled at the bending portion due to the pulling action of the first wrapping member 5 by the support member 7' when the second wrapping member 6 is compressed, which is the same as the support member 7. Thus, the coating mechanism 3 of the present invention is advantageous in that it can be flexibly bent at the time of the rotational operation of the rotating mechanism 8, and the coating mechanism 3 is prevented from being creased or wrinkled at the time of the rotational operation of the rotating mechanism 8.

Referring again to fig. 13, a plurality of support members 7 'are arranged in the lateral direction of the electronic device, forming a space d between the support members 7'. The arrangement of the support members 7 'as shown in fig. 12-16 is merely illustrative, as with the support members 7, and the grouping, number and arrangement of the support members 7' are arranged according to actual design requirements so as to prevent the coating mechanism 3 from creasing or wrinkling. Moreover, the distance between the supporting members 7 'may be different according to the material and hardness of the supporting members 7', even if the supporting members 7 are distributed in a non-equidistant manner, and may be non-linear, i.e. staggered.

In the foregoing description of the embodiment, the coating mechanism 3 comprises two separate first and second coating members 5, 6 connected by a support assembly. In fact, the first and second covering members 5 and 6 may be integral in themselves, as shown in fig. 17 and 18, and even if the support assembly is eliminated from the first and second covering members 5 and 6, the first and second covering members 5 and 6 are one integral piece joined together.

Further, while the covering mechanism 3 and the rotating mechanism 8 are described as two separate members in describing the present invention, it will be understood by those skilled in the art that the covering mechanism 3 and the rotating mechanism 8 may be manufactured by integral molding to form the connecting device of the present invention.

In the present invention, the first covering member 5 and the second covering member 6 of the covering mechanism 3 and the support member may be made of the same material or different materials. The covering means 3 is able to provide protection, connection and aesthetic features, and any suitable organic material having a certain toughness and elasticity may be used to make the covering means 3, such as silicone.

In the drawings, the through hole for fixing of the covering mechanism 3 is a circular hole, however, an oblong hole for fixing may be designed for the covering mechanism 3, and the lengthwise direction of the oblong hole is along the longitudinal direction of the electronic device, so that a degree of freedom may be left for the movement of the first covering member 5 and the second covering member 6 of the covering mechanism 3 during bending, and the first covering member 5 and the second covering member 6 may be made to slide along the longitudinal direction of the electronic device during bending, so that a person skilled in the art can design the covering mechanism 3 with different bending modes.

The rotating mechanism can avoid crease marks and wrinkles on the pressure surface of the coating mechanism, so that the rotating mechanism can rotate more flexibly and with higher quality, the man-machine interaction is improved, and a user can obtain better experience. As shown in fig. 19 to 22, the electronic apparatus of the present invention realizes flexible, high-quality rotation of 360 degrees between the first body 1 and the second body 2 by the rotating mechanism of the present invention.

In the previous figures, the first body 1 and the second body 2 are a display side and a system side, respectively, and have a large difference in appearance. However, the shape design of the first body 1 and the second body 2 and the overall design of the electronic device may also form different solutions, presenting different variations, as briefly described below.

As shown in fig. 23 and 24, the electronic apparatus also includes a first body 1, a second body 2 and a rotating means 3 therebetween, however, in appearance, the electronic apparatus employs an integral display screen which can be rotated 360 degrees by means of the rotating means 3. Obviously, the electronic device may be embodied as a tablet computer.

Referring again to fig. 25, at least the first body 1 has a display screen forming a display portion, and the second body 2 also has a physical keyboard structure. Note that a small display screen for displaying information with a hint or auxiliary content is provided on the back side of the electronic device at a location corresponding to the rotating means 3. In addition, as an alternative, on the same side as the first body 1 and the display screen, the electronic device may be equipped with another small display screen at a position corresponding to the rotating means 3, and may also be used to display information with a prompt or auxiliary content.

Referring to fig. 26 again, the electronic device is equipped with a small display screen at a position corresponding to the rotating device 3, and both the first body 1 and the second body 2 of the electronic device may have a display screen, such as a touch screen. Similarly, as an alternative, on the back side of the electronic device, a small display screen may be mounted in a position corresponding to the rotating means 3, the small display screen being located between the two separate display screens of the first body 1 and the second body 2, and also being used to display information with a hint or auxiliary content.

Furthermore, although the electronic apparatus shown in fig. 23 and 24 is provided with an integral display screen, a separate small display screen for displaying information with a hint or an auxiliary content may be displayed at a portion corresponding to the rotating means 3 by electronic control. In addition, as an alternative, another small display screen may be mounted on the back side of the electronic apparatus corresponding to the rotating means 3, as in the embodiment of fig. 25 and 26.

The embodiments of the connecting device and the electronic apparatus according to the present invention have been described above. The specific features of the connecting device and the electronic apparatus of the present invention, such as shape, size and position, can be specifically designed by the functions of the above disclosed features, which can be realized by those skilled in the art. Moreover, the technical features disclosed above are not limited to the combinations with other features disclosed, and other combinations between the technical features can be performed by those skilled in the art according to the purpose of the invention, so as to achieve the purpose of the invention.
