Therefore, when the user wants to rotate the display module 8 in the backward direction 10, the force applied by the user to the display module 8 must be greater than the frictional resistance between the ratchet 53 and the two first friction ring pieces 542. The pawl 552 has sufficient force to push the ratchet 53 to rotate, so that the second bracket 4 can smoothly rotate relative to the first bracket 2 in the reclining direction 10.

With the aforementioned design, since the friction resistance of the hinge 5 is large and it is not easy to be rotated, the support frame module 100 can stably position the display module 8 at the selected angular position. Therefore, when the user presses and presses the display module 8, the display module 8 can maintain a stable state without swaying or tilting backward.

Referring to Figures 7 and 8, when the user rotates in a forward tilt direction 30 When the module 8 is used, the ratchet 53 is stationary, and the second bracket 4 drives the pawl 552 to rotate in the forward tilting direction 30 to disengage the latching claw portion 557 from the latching groove 533, and the latching claw portion 557 of the pawl 552. A slope 534 of the plurality of oblique teeth 532 is sequentially slid so that the click claw portion 557 of the pawl 552 can rotate along the outer circumference of the ratchet 53. When the user rotates the display module 8 to the desired angular position, the latching claw portion 557 of the pawl 552 is positioned in the corresponding slot 533 of the ratchet 53. Since the display module 8 drives the second bracket 4 to rotate in the forward tilt direction 30, the pawl 552 does not need to overcome the frictional resistance between the ratchet 53 and the two first friction ring segments 542 to drive the ratchet 53 to rotate, and therefore, the hinge The frictional resistance of 5 is small, so that the user can easily rotate the display module 8 without applying excessive force to adjust and store the angle of the display module 8.

It should be noted that the number of the hinge 5 and the hinge 3 in the preferred embodiment are two, but only one hinge 5 and one hinge 3 may be included.

In addition, the support frame module 100 in the preferred embodiment may not include the fixed bracket 1 and the two hinges 3, and the first bracket 2 may be directly disposed on the base 7.

In summary, by the arrangement of the ratchet 53 and the pawl 552 of the brake mechanism 55, when the display module 8 and the second bracket 4 are rotated in the reclining direction 10, the hinge 5 has a large frictional resistance and is not easily rotated. Therefore, the force applied by the user to the display module 8 must be greater than the frictional resistance between the ratchet 53 and the two first friction ring pieces 542, so that the pawl 552 has sufficient force to push the ratchet 53 to rotate, and the second bracket 4 In order to smoothly rotate in the reclining direction 10 relative to the first bracket 2. Therefore, when the user presses the display module 8 by touch The display module 8 can maintain a stable state without swaying or tilting backwards. In addition, when the display module 8 and the second bracket 4 are rotated in the forward tilting direction 30, since the pawl 552 does not need to overcome the frictional resistance between the ratchet 53 and the two first friction ring segments 542 to drive the ratchet 53 to rotate, The frictional resistance of the hinge 5 is small, so that the user can easily rotate the display module 8 without applying excessive force to adjust and store the angle of the display module 8, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
