1 is a schematic view of a conventional pivot device 1000. The conventional pivot device includes a pivot shaft 11, a carrier member 12 and a connecting member 13. The carrier member 12 can be coupled to a display module (not shown). The connecting member 13 can be connected to a supporting device (not shown). The bearing member 12 and the connecting member 13 are pivoted on the pivot shaft 11 , and the bearing member 12 can pivot 1 to the pivot center 11 . And the connecting member 13 is rotated by an angle, whereby the user has to adjust an angle of the display module relative to the supporting device. In order to control the angular range of the rotating carrier 12, the carrier 12 has a limiting slot 121. The connecting member 13 has a protrusion 131 disposed in the limiting slot 121. When the carrier 12 rotates relative to the pivot 11, the limit is limited. The end of the groove 121 is directly in contact with the protrusion 131, so that the carrier 12 can be prevented from continuing to rotate, that is, the range of the rotation angle of the carrier 12 is controlled by the size of the limiting groove 121.

A disadvantage of the above-mentioned conventional support device is that the support member 12 must additionally form a limiting slot 121, and the connecting member 13 must be additionally provided with a protrusion 131, so that the shape of the carrier member 12 and the connecting member 13 is relatively complicated, and the known pivot The overall volume of the shaft device 1000 will also be larger. In addition, in order to prevent the end of the pivot 11 from being worn by the carrier 12 at each rotation, the conventional pivot device 1000 is provided with a plurality of washers 14 in a portion where the contact area between the pivot 11 and the carrier 12 is large.

In the radial direction R, there is a non-circular body section. The body cross section has two first straight lines 211 and two first arc lines 212, and the first straight line 211 and the first arc line 212 are alternately connected in a wraparound manner. Wherein, the first arc 212 extends from the center of the axial direction C, and the head 22 is connected to one end of the body 21, and the head 22 has a head section in the radial direction R, and the head section Greater than the body section.

Figure 5 is a perspective view of the carrier member 3. The carrier member 3 has a plate body 32 and two first side wings 31 extending from the two sides of the plate body 32. In other words, the carrier member 3 is substantially U-shaped. The board body 32 can be fixed by a display module. A first shaft hole 311 is formed in each of the first side wings 31.

Hereinafter, only a single first axial hole 311 will be described as an example, and the other first axial hole 311 has the same shape and structure, and thus will not be further described. In detail, as shown in FIG. 6, the first shaft hole 311 has a non-circular shaft hole section in the radial direction R, and the shaft hole section has two opposite second straight lines 312b and two opposite third straight lines 312c. The two opposite second arcs 312d are centered at a point where the axial direction C intersects the cross section of the shaft hole, and each of the second straight lines 312b and the third straight line 312c intersect at a connection point 312a. With respect to the axial direction C, the second straight lines 312b are located at obliquely opposite to each other, that is, with the axial direction C as the axis, and the second straight lines 312b form a central symmetry with each other. Similarly, the third The straight lines 312c are also located at diagonally opposite one another, that is, with the axial direction C as the axis, and the third straight lines 312c form a center symmetry with each other. Therefore, each of the connection points 312a is located between each of the second straight lines 312b and the third straight lines 312c; and the second arcs 312d are also in contact with the second straight lines 312b and the third straight lines 312c, respectively. The distance D1 from each connection point to the center of the circle is smaller than the distance D2 from any point of the second arc 312d to the center of the circle.

As shown in FIG. 3, the connecting member 4 has a plate body 42 and two second side wings 41 extending from the two side edges of the plate body 42, that is, a U-shape, and the plate body 42 can be connected to the first side. In addition, a second shaft hole 411 is formed in each of the second side wings 41. The body 21 is sequentially disposed in one of the first shaft holes 311, one of the second shaft holes 411, the torsion spring 5, another second shaft hole 411, and another first axis. After the hole 311, the head 22 bears against one of the first side flaps 31, and the lock attachment 6 is disposed at the other end of the body 21 relative to the head 22. In this embodiment, the lock attachment 6 can be a The nut is screwed to the other end of the body 21. The second shaft hole 411 has a corresponding shape with the body section of the body 21, that is, a non-circular shape, so that the connecting member 4 cannot rotate relative to the body 21. The two ends of the torsion springs 5 are respectively connected to the carrier member 3 and the connecting member 4. When the carrier member 3 rotates relative to the body 21 and the connecting member 4, the torsion spring 5 can be simultaneously twisted to generate a torque. The display module having a certain weight is connected to the carrier 3, and the torque is balanced with the gravity of the display and the friction between the components, thereby maintaining the effect of the display module at a viewing angle.

Please refer to FIG. 6 to show the state before the carrier 3 is rotated (in this case, when the display module is disposed on the carrier 3, it is perpendicular to the ground), when the body 21 is worn on the carrier 3, each first straight line 211 is a surface. For each of the connection points 312a, each of the second straight lines 312b, and each of the third straight lines 312c, only the connection point 312a is in contact with the first straight line 211. That is, one of the first straight lines 211 and each of the second straight lines 312b has a first angle θ1, and each of the first straight lines 211 and each of the third straight lines 312c has a second angle θ2. Each of the first straight lines 211 is selectively adjacent to one of the second straight line 312b and the third straight line 312c, so that the carrier 3 can be axially oriented with respect to the body 21 and rotated relative to the body 21 at a first position. Transforms with the second position.

7 is a schematic diagram showing the carrier 3 rotating counterclockwise with respect to the body 21, and FIG. 8 is a schematic diagram showing the carrier 3 rotating clockwise with respect to the body 21, when the carrier 3 is axially oriented with respect to the axis C, relative to When the body 21 is rotated counterclockwise by the first angle θ1, the second arc 312d slides on the first arc 212 with respect to the relative actuation relationship between the body section and the shaft hole section, and the carrier 3 is The connecting point 312a is rotated to the fulcrum to bring the second straight line 312b close to the first straight line 211. At this time, the carrier 3 is located at a first position, and the first angle between the second straight line 312b and the first straight line 211 is originally located. Θ1 thus becomes 0 degree, that is, the state in which the first angle θ1 is the smallest and the second angle θ2 is the largest, and since the connection point 312a and the second straight line 312b abut against the first straight line 211, the bearing member cannot be made Then perform relative rotation.

At the viewing angle shown in FIG. 9, when the carrier 3 is axially oriented with the axial direction C and rotated clockwise relative to the body 21 by a second angle θ2, the carrier 3 is in a second position, the second arc The 312d slides on the first arc 212, and the carrier 3 rotates with the connection point 312a as a fulcrum to make the third line 312c close to the first line 211, and is originally located between the third line 312c and the first line 211. The second angle θ2 will become 0 degree, that is, the state in which the first angle θ1 is the largest and the second angle θ2 is the smallest. Similarly, since the connection point 312a and the third straight line 312c have abutted on the first line 211. , and can no longer make relative rotation.

As described above, by controlling the inclination angles of the second straight line 312b and the third straight line 312c with respect to the first straight lines 211 of the body 21 (ie, the first angle θ1 and the second angle θ2), the carrier 3 can be controlled to be relatively The rotation angle range of the shaft 2 and the connecting member 4 further controls the rotation angle of the display module relative to the support frame. For example, in a preferred embodiment of the present invention, when the first angle θ1 is 5 degrees and the second angle θ2 is 25 degrees, the carrier 3 can be 5 degrees and 25 degrees with respect to the shaft 2 and the connecting member 4 However, in other embodiments of the present invention, at least the first angle θ1 and the second angle θ2 are controlled to be between 0 and 70 degrees.

However, those skilled in the art can also make the rotation only in a single direction according to the concept of the present creation. In detail, with respect to the viewing angles of FIGS. 6 to 8, the third straight line 312c is designed to be parallel to the side surface 211 as needed, and the second straight line 312b and the first straight line 211 have a first angle θ1, The carrier 3 can only be rotated counterclockwise relative to the shaft 2 and the connecting member 4, or the second straight line 312b can be designed to be parallel to the first straight line 211, and the third straight line 312c and the first straight line The second angle θ2 is 211, so that the carrier 3 can only be rotated clockwise with respect to the shaft 2 and the connecting member 4, and details are not described herein.

In this embodiment, the first shaft hole 311 has the same shape. However, in other embodiments of the present invention, at least one of the first shaft holes 311 may be a circle, and the other The one shaft hole 311 maintains the non-circular shape described in the preceding paragraph, and the effect of restricting the rotation angle of the carrier 3 can also be achieved. In other embodiments of the present invention, as shown in FIG. 9, the number of the shaft 2, the torsion spring 5, and the lock attachment 6 may be two, and the shaft 2 passes through each of the first shaft holes 311 of the carrier 3, respectively. The torsion springs 5 and the lock attachments 6 are respectively sleeved on the respective shafts 2, and the detailed structure thereof will not be described herein.

In summary, the creation of the pivot device through the specific shape of the first shaft hole of the carrier can effectively limit the rotation angle of the carrier relative to the shaft and the connecting member, compared with the conventional pivot device, the creation The shape of the carrier and the connecting member is more simplified, thereby effectively reducing the volume of the pivot device and reducing the production cost.
