Background technique

With the rapid development of integrated circuit manufacturing technology and the continuous development and progress of electronic technology, all kinds of electronic products are moving towards "digitalization". Moreover, in order to meet the considerations of portability and practicability, the design of electronic products tends to be thin, short, multi-functional, and fast-processing as design specifications, so that the products produced can be more easily carried and more in line with modern requirements. Daily needs. Especially after the popularity of multimedia electronic products, with its powerful computing power, it can easily process various digital data such as sound effects, images, and patterns, and provide consumers with high-quality and high-quality entertainment effects. High-end computer products are widely loved and used by the public.

In particular, with the development and maturity of network application technology, through wired or wireless network connections, consumers can surf the Internet at any place and at any time, and transmit or exchange various messages and data. Under such circumstances, consumers will obviously be more willing to purchase and use various portable computer products, such as palmtop computers, laptop computers, or notebook computers, so as to exchange information with remote users via the Internet, Or obtain various voice or image data. In other words, after combining the powerful data processing capabilities of the new generation of computers and the communication services provided by the network connection, consumers will be able to easily watch multimedia programs on the Internet or browse instant news information through the computer screen.

In order to provide consumers with more convenience in operation, a new generation of portable computers, such as tablet computers (TABLE PC), adopts a touch screen, so that consumers can input data through the screen, Or control various functions. In addition, in order to allow consumers to browse the screen from more angles, the design of the hinge between the screen and the host, in addition to the traditional flip-top design, allows the screen to be lifted upwards, allowing 180-degree rotation on the upper surface of the host. Left and right rotation, so that consumers can browse the pictures on the screen from all directions. In other words, in a new type of portable computer, the screen can be rotated in the left and right directions in addition to the action of raising or lowering the screen in the pitch direction.

In order to enable the screen to rotate up and down and left and right at the same time, the new generation of portable computers has abandoned the traditional way of installing rotating shafts on the left and right sides of the bottom of the screen in traditional notebook computers, and changed it to a rotating shaft at the bottom of the screen. At the central part, a group of rotating shaft devices are assembled. Moreover, since the hinge device can not only rotate in the up and down direction, but also in the left and right directions, the computer screen can be lifted up or closed down on the host computer, and can also be turned on the host computer. Rotation in left and right directions.

Although by assembling a single rotating shaft device between the computer screen and the host, the rotation effects in the above two directions can be provided at the same time. However, most of the rotating shaft devices currently on the market still have quite a few disadvantages. In particular, for most of the rotating shaft devices currently on the market, the positioning function is generally not reliable enough, and the positioning gap is too large. Therefore, after the screen rotates to the positioning, it lacks strong fixation and support, and a slight vibration will still occur. swing, causing consumers to easily feel uncomfortable when watching the screen. Secondly, when the screen is rotating, because the friction torque provided by the rotating shaft device is generally insufficient, the entire screen cannot be rotated smoothly and will shake.

The rotating shaft device 1 can be assembled and connected between a screen of a portable computer and the host, so that the screen can be pulled up and down and rotated left and right on the upper surface of the host. As shown in the figure, the main components of the rotating shaft device 1 are divided into a strip-shaped plate 10 , a vertical rotating shaft 11 , two horizontal rotating shafts 12 , an elastic member 13 , and a fixing member 14 . Wherein, the elongated plate 10 is the main body constituting the entire rotating shaft device 1 . The vertical shaft 11 is protruded vertically downward from the central position of the lower surface of the elongated plate 10, and is used for assembling and inserting into the corresponding hole on the main machine casing, allowing the elongated plate 10 to move left and right on the upper surface of the main machine. direction of rotation. The horizontal rotating shafts 12 are respectively connected to two ends of the elongated plate 10 , and extend and protrude to both sides along the direction of the elongated plate 10 . The horizontal rotating shaft 12 can rotate relative to the elongated plate along its axial direction. When the horizontal rotating shaft 12 is combined with the groove corresponding to the lower edge of the screen shell, it can drive the entire screen to rotate up and down.

It is worth noting that, at the center of the elongated plate 10, a central circular hole 101 is made through the plate. Moreover, the above-mentioned vertical rotating shaft 11 is just connected under the central circular hole 101 . Since the vertical rotating shaft 11 is also a hollow cylindrical structure, it penetrates upwards through the central circular hole 101 of the elongated plate 10 . In a preferred embodiment, the vertical shaft 11 and the elongated plate 10 are integrally formed, and the central hole 101 through which it passes can be used for laying various signal lines or wires for connecting the screen and the host. power cable.

Still referring to FIG. 1 , on the upper surface of the elongated plate 10 , on both sides of the central circular hole 101 , rings 102 penetrating through the elongated plate 10 are respectively provided for assembling the elastic member 13 provided by the present invention. As shown in the figure, the collar 102 protrudes upwards from the upper surface of the elongated plate 10, and threads are made on the inner wall of the collar 102, so that the elastic member 13 is screwed into and fixed in the collar 102 . It should be particularly pointed out that after being screwed into the collar 102 passing through the elongated plate 10 , the elastic member 13 will protrude downward from the lower surface of the elongated plate 10 . When the entire rotating shaft device 10 is assembled on the main machine, the front end of the elastic member 13 will just touch the main machine casing, so that the rotation of the elongated plate 10 is smoother by virtue of its elastic pressing force. In addition, a hole-shaped depression corresponding to the elastic member 13 is provided on the upper surface of the main machine casing. Once the elongated plate 10 is rotated to a fixed position, the front end of the elastic member 13 will just protrude and be stuck in the hole-shaped depression, and The effect of fixing the elongated plate 10 is produced.

In one embodiment of the present invention, the elastic member 13 is composed of a spring ball screw. Please refer to FIG. 2 , which shows the detailed structure of the elastic member 13 . The elastic member 13 includes a sleeve 131 , a spring 132 and a steel ball 133 . A screw thread 131a is made on the shell of the sleeve 131 so that it can be screwed into and screwed into the collar 102 of the elongated plate 10 with the opening facing downward. The spring 132 is plugged into the sleeve 131 , and the front end of the spring 132 is connected to the steel ball 133 . As shown in the figure, since the diameter of the steel ball 133 is larger than the diameter of the opening of the sleeve 131 , it will be clamped in the opening of the sleeve 131 and elastically pressed by the spring 132 .

Generally speaking, in order to keep enough space between the screen and the host, the screen can be rotated left and right and flipped up and down smoothly. In an actual mechanism, the position of the horizontal rotating shaft 12 is higher than the upper surface of the elongated plate 10 to generate a step-like height difference, so as to provide enough connection space between the screen and the host. As shown in FIG. 1 , upwardly protruding blocks 103 are respectively provided at both ends of the upper surface of the elongated plate 10 . In a preferred embodiment, the block 103 here is also integrally formed and connected with the elongated plate 10 .

On the upper surface of each block 103 there is a fixing member 14 extending outward along the direction of the elongated plate 10 . Each fixing member 14 , as shown in FIG. 1 , can be divided into two parts: a flat plate 141 and a columnar structure 142 . Wherein, two small holes 141 a are provided on the plate 141 , and the plate 141 can be fixed on the upper surface of the block 103 by means of rivets or screws. The columnar structure 142 is connected to the front end of the flat plate 141 and extends outward for connecting with the horizontal shaft 12 .

Still referring to FIG. 1 , the horizontal rotating shaft 12 is connected to the front end of the fixing member 14 and can rotate relative to the fixing member 14 . Each horizontal rotating shaft 12 can also be divided into two parts: a columnar structure 121 and a flat plate 122 . Wherein, the columnar structure 121 is connected to the front end of the columnar structure 142 of the fixing member 14 , and can rotate relative to the columnar structure 142 along its axial direction. The flat plate 122 extends outward from the front end of the columnar structure 121 . Two small holes 122a are formed on the flat plate 122, and the horizontal shaft 12 can be locked to the lower edge of the screen by screws.

Generally speaking, when the rotating shaft device 1 is assembled on the computer mainframe, at least one ball bearing 15 will be sheathed on the above-mentioned vertical rotating shaft 11, so as to be assembled and inserted into the corresponding hole on the main frame, so that the rotating shaft device 1 can Smooth left and right rotation on the host. In the present invention, as shown in FIG. 1 , two sets of ball bearings 15 a and 15 b are used to sequentially pass through the vertical rotating shaft 11 as a basis for rotation. In addition, a nut 16 is used under the ball bearing 15 for locking, so as to lock the rotating shaft device 1 in the computer host.

On the basis of the above-mentioned rotating shaft device 1, the present invention also provides a corresponding design of the main body casing and the screen casing, so as to be able to be assembled and connected with the above-mentioned rotating shaft device 1, and fully exert the unique functions of the rotating shaft device. Still referring to FIG. 1 , on the upper surface of the casing of the host 2 , near the side, a downwardly recessed disk base 20 is provided. A central hole 201 is formed at the center of the disc base 20 , corresponding to the vertical shaft 11 on the lower side of the shaft device 1 . After assembling the vertical shaft 11 of the shaft device 1 into the central hole 201 , the strip-shaped plate 10 can rotate left and right on the upper surface of the disk base 20 .

It is worth noting that an annular thin plate 201a is disposed on the inner wall of the central hole 201 of the disc base 20 for placing the annular ball bearing 15a on the upper surface of the annular thin plate 201a in the central hole 201 . Another annular ball bearing 15b is placed on the lower side of the annular thin plate 201a. In this way, when the vertical rotating shaft 11 of the rotating shaft device 1 passes through the ball bearing 15a, the annular thin plate 201a and the ball bearing 15b from top to bottom, the above-mentioned nut 16 can be used to move the ball bearing 15b from the lower surface of the ball bearing 15b. These components are locked on the vertical shaft 11 .

In addition, hole-shaped depressions 202 are respectively made on the surface of the disk base 20 on both sides of the central hole 201 . When the rotating shaft device 1 is rotated to a fixed position, the steel ball 133 at the front end of the elastic member 13 just protrudes downwards and is stuck in the corresponding hole-shaped recess 202 , thereby producing the effect of fixing the rotating shaft device 1 .

It should be pointed out that in order to prevent the screen from rotating more than 180 degrees when the screen is rotated left and right, the circuit connecting the screen and the host in the hinge device 1 will be excessively twisted or cause the circuit to become knotted or broken. Shaped plate 10 lower surface, make a protruding post (not shown in the figure) that protrudes downwards. Moreover, on the upper surface of the disc base 20 , a semicircular arc groove 203 is provided at a position surrounding the central hole 201 . When the rotating shaft device 1 is assembled on the disc base 20 , the protrusions on the lower surface of the elongated plate 10 will just fit into the arc groove 203 . In this way, when the elongated plate 10 rotates on the disc base 20 , the protrusion will slide back and forth along the arc groove 203 . Since the arc groove 203 is only half-shaped, the elongated wrench 10 can rotate 180 degrees at most, and the direction of rotation is also limited by the position of the boss.

On the other hand, at the lower edge of the housing of the screen 3 , there are two sets of locking bases 30 corresponding to the above-mentioned horizontal rotating shaft 12 for assembling the rotating shaft device 1 . Each locking base 30 includes a semicircular arc-shaped groove 30a and two screw holes 30b. When assembling the rotating shaft device 1 and the screen 3, the cylindrical structure 142 of the above-mentioned fixing member 14 and the cylindrical structure 121 of the horizontal rotating shaft 12 are just assembled and accommodated in the arc-shaped groove 30a; Screws are used to pass through the small holes 122a and 30b in sequence to be fixedly installed on the locking base 30 .

For the convenience of understanding, please refer to FIG. 3 , which shows the assembly relationship among the above-mentioned rotating shaft device 1 , host 2 and screen 3 . Wherein, the disc base 20 is made at the central position on the rear side of the upper surface of the main body 2 casing, and the two locking bases 30 are distributed at the center of the lower edge of the screen 3 casing, and are just in line with the rotating shaft device 1 The horizontal axis of rotation 12 is relative.

Using the design of the present invention has considerable advantages:

(1) First of all, since the rotating shaft device of the present invention has two elastic members protruding downwards, when the elongated plate rotates left and right on the main machine casing, the elastic members will just touch the upper surface of the disc base , so that the rotation of the entire strip plate is smoother, thereby reducing the shaking degree of the screen when rotating.

(2) In the present invention, a hole-shaped depression is provided on the upper surface of the disc base, so that when the screen reaches the positioning position, the above-mentioned elastic member will just protrude downward and be stuck in the hole-shaped depression, thereby achieving the purpose of strengthening and fixing the screen Effect.

(3) In addition, in the present invention, protruding posts are provided on the lower surface of the elongated plate, and corresponding semicircular arc-shaped concave grooves are provided on the disc base. In this way, the rotation direction and angle of the screen can be effectively restricted, and the accident of twisting and breaking of the connection between the host and the screen due to excessive rotation of the screen can be prevented.

Although the present invention is illustrated above with preferred examples, they are not intended to limit the spirit and protection scope of the present invention. Those skilled in the art can easily understand and utilize other elements or methods to produce the same effect. Therefore, modifications made without departing from the spirit and scope of the present invention should be included in the scope of the following claims of the present application.
