Detailed Description

Referring to fig. 3 to 10, an embodiment of the present invention is described, and the number and shape of the embodiments are mentioned in the corresponding drawings, which are only for illustrating the embodiments of the present invention, so as to facilitate understanding of the content of the embodiments, and not to limit the scope of the claims.

As shown in fig. 3 and 4, the present embodiment provides an adjustable tilt angle display, and the adjustable tilt angle display supporting device 100 is used for carrying a display (not shown), so that the display can be at various tilt angles by adjusting the adjustable tilt angle display supporting device 100, thereby being convenient for people to watch or operate. The display may be a display, a tablet computer, a liquid crystal display, a monitor, a computer-integrated machine, a navigation device, or other objects to be presented with different inclinations in this embodiment, which is not limited herein.

The display supporting device 100 with adjustable inclination angle comprises a base module 1, a bearing piece 2, two slide rail modules 3, a supporting frame 4 and two buckling modules 5. The base module 1 is pivotally disposed at one end of the carrier 2, the two slide rail modules 3 are respectively mounted at the left and right sides of the carrier 2, the base module 1 is pivotally disposed at one end of the support frame 4, the other end of the support frame 4 is connected to the two slide rail modules 3, the two fastening modules 5 are respectively mounted at the left and right sides of the carrier 2 and located at the outer sides of the two slide rail modules 3, and the two fastening modules 5 are respectively used for limiting the two slide rail modules 3. It should be noted that, the display supporting apparatus 100 with adjustable tilt angle of the present embodiment is exemplified by including two sets of slide rail modules 3 and fastening modules 5 that are matched, but in another embodiment, which is not shown, the display supporting apparatus 100 with adjustable tilt angle may also include only one set of slide rail modules 3 and fastening modules 5 that are matched.

In the following disclosure, the respective structures of the base module 1, the carrier 2, the slide rail module 3, the support frame 4, and the fastening module 5 will be described, and the connection relationship therebetween will be described in good time.

As shown in fig. 4 and 5, the base module 1 has a base 11, two hinge structures 12, and a plurality of rollers 13. The base 11 is configured to be disposed on a working surface (e.g., a table top), and the base 11 is substantially H-shaped in the present embodiment and includes two front end portions 111 and two rear end portions 112. Wherein, a groove 113 is formed between the two rear ends 112 of the base 11.

Furthermore, the two hinge structures 12 are respectively embedded in the two rear ends 112 of the base 11, and the two hinge structures 12 are located substantially in the two rear end 112 blocks adjacent to the bottom of the recess 113. The rollers 13 are respectively pivoted to two rear ends 112 of the base 11, and the rollers 13 are located in two rear end 112 blocks away from the bottom of the groove 113. Each roller 13 partially protrudes out of the bottom surface of the base 11 and is configured to be rollably disposed on a working surface.

The carrier 2 is substantially flat in this embodiment, and the carrier 2 has a front surface 21 and a back surface 22 on opposite sides, the front surface 21 of the carrier 2 is used for carrying the object, and the back surface 22 of the carrier 2 is used for mounting the slide rail module 3 and the fastening module 5. Furthermore, the bottom edge of the carrier 2 is pivotally connected to the front end portions 111 of the base module 1 along a first axis C1, so that the carrier 2 can pivot relative to the base module 1 about the first axis C1.

The two sliding rail modules 3 are respectively installed at the left and right sides of the back surface 22 of the upper half block of the carrier 2, and the two sliding rail modules 3 are long and are approximately parallel to each other in the embodiment. In this embodiment, since the two rail modules 3 have substantially the same structure, for convenience of understanding and avoiding redundancy, only the structure of a single rail module 3 is described below, but it is not excluded that the two rail modules 3 have not completely the same structure in practical application.

The slide rail module 3 has a rail 31 and a slider unit 32 movably disposed in the rail 31. The rail 31 is elongated and fixed to the back surface 22 of the carrier 2, and the rail 31 is substantially perpendicular to the first axis C1. The slider unit 32 includes a slider 321, a coupling member 322, a positioning member 323, and a fixing member 324 (e.g., screw and nut). The sliding member 321 is slidably disposed on the rail 31, and the coupling member 322 is fixed to the sliding member 321 and positioned on the rail 31100 at various angles of inclination, so as to facilitate the viewing or operation of the person. The display may be a display, a tablet computer, a liquid crystal display, a monitor, a computer-integrated machine, a navigation device, or other objects to be presented with different inclinations in this embodiment, which is not limited herein.

The slide rail module 3 has a rail 31 and a slider unit 32 movably disposed in the rail 31. The rail 31 is elongated and fixed to the back surface 22 of the carrier 2, and the rail 31 is substantially perpendicular to the first axis C1. The slider unit 32 includes a slider 321, a coupling member 322, a positioning member 323, and a fixing member 324 (e.g., screw and nut). The sliding member 321 is slidably disposed on the rail 31, and the connecting member 322 is fixed to the sliding member 321 and located at a projection area corresponding to the rail 31, and protrudes beyond the edge of the carrier 2 (as shown in fig. 3), so that a user faces the left and right hands of the display and extends to the left and right sides of the display to press the pressing portion 511 of the fastening member 51.

Thus, the fastening member 51 can be pressed by the pressing portion 511 to pivot between the fastening position (fig. 6) and the releasing position (fig. 7) with respect to the carrier 2 about a third axis C3. And, the angle formed by the pressing portion 511 and the carrier 2 when the fastening member 51 is located at the fastening position is larger than the angle formed by the pressing portion 511 and the carrier 2 when the fastening member 51 is located at the releasing position. In other words, when the pressing portion 511 is pressed, the pressing portion 511 gradually rotates toward the carrier 2 with the third axis C3 as the axis.

Furthermore, a plurality of engaging areas 5121 are formed at the end edge of the fastening portion 512 away from the pressing portion 511 (i.e. adjacent to the sliding rail module 3), and the alignment direction of the engaging areas 5121 is substantially parallel to the track 31. That is, the engaging zones 5121 are arranged in a row substantially parallel to the third axis C3, and the distance between the two engaging zones 5121 located at opposite ends of the row of engaging zones 5121 is greater than the distance between the two reset units 52.

It should be noted that, in the embodiment, two cylindrical protruding columns are taken as an example of the engaging portion 3233, and the engaging regions 5121 include a plurality of notches concavely formed from the end edges of the engaging portion 512, and the number of notches included in each engaging region is equal to the number of protruding columns of the engaging portion, that is, each engaging region 5121 of the embodiment corresponds to two notches, and any notch is a structure capable of geometrically engaging with the protruding columns, but is not limited thereto. For example, the engaging portion 3233 can be a single protrusion, and the engaging region 5121 can be a single notch; alternatively, the engaging portion 3233 may be formed as a notch, and the engaging portion 5121 may be formed as a protruding post corresponding to the notch.

The above description is given of the structure of the tilt-adjustable display supporting apparatus 100 according to the present embodiment, but the implementation structure can be adjusted according to the needs of the designer, and the tilt-adjustable display supporting apparatus 100 is not limited to the embodiment. It should be noted that, in this embodiment, the hinge structure 12 and the reset unit 52 are each exemplified by a structure formed by springs, various gaskets, screws, and nuts (not labeled) (particularly, the hinge structure 12 may include flat gaskets, elastic gaskets, angle limiting gaskets, and structures such as loosening gaskets and fixing nuts or rivets (not labeled in the drawings for simplicity), so as to generate a yaw friction resistance moment to improve the hand feeling during the pitching operation, which may be implemented by referring to some known technologies related to this function), but in practical applications, the hinge structure 12 and the reset unit 52 are not limited to the structures shown in the drawings.

The operation of the tilt-adjustable display support apparatus 100 is described below. When the user presses the pressing portion 511 of the locking module 5 to locate the locking member 51 at the release position (as shown in fig. 7), that is, the pressing portion 511 is pressed, the locking member 51 pivots to separate the locking region 5121 and the locking region 3233 from each other, and at this time, the slider unit 32 can move along the track 31 to enable the position of the locking region 3233 to selectively correspond to one of the locking regions 5121.

Further, when the positions of the engaging portions 3233 correspond to the different engaging regions 5121, the carrier 2 and the base module 1 form different angles, and the angle formed by the carrier 2 and the base module 1 includes at least three angles between 15-75 degrees. In the present embodiment, the included angle formed by the carrier 2 and the base module 1 includes ten angles between 15-67 degrees, and in order to avoid being too complicated, the present embodiment only shows three angles in the drawings, namely, 67 degrees in fig. 8, 45 degrees in fig. 9, and 15 degrees in fig. 10.

Then, after the angle formed by the carrier 2 and the base module 1 is selected by the user, the pressing portion 511 is released, so that the fastening member 51 is located at the fastening position (as shown in fig. 6) through the reset unit 52, and the fastening portion 3233 is fastened to one of the fastening regions 5121 (i.e., the fastening region 5121 corresponding to the user's selected suitable angle). Therefore, the carrier 2 of the tilt-adjustable display supporting apparatus 100 of the present embodiment is maintained at the angle selected by the user, and the weight of the object mounted on the tilt-adjustable display supporting apparatus 100 falls on the support frame 4 and the base module 1, so as to prevent the object from falling down due to unstable center of gravity or touch of the touch screen (e.g. during game playing of the touch screen).
