Support mechanism for pivoting mechanism and its application

The present invention relates to a pivoting mechanism, and more particularly to a pivoting mechanism that has a long service life and is simple to operate, and a support frame for its application.

A desktop display is typically placed on a table top by a base having a pivoting mechanism. Since the pivoting mechanism is a mechanism that can be rotated, the user can adjust the display screen to obtain the best viewing angle.

However, most of the common pivoting mechanisms use torsion or gears, which not only tend to wear the components, but also can only be rotated to a specific angle, which has a preset angle limit, which is quite equivalent for the user. inconvenient.

The invention utilizes the friction generated by the turntable (or with the limit plate) and the soft rotating component to adjust and fix the angle, and can be applied to general consumer electronic products.

The present invention provides a pivoting mechanism adapted to be disposed on a base, the pivoting mechanism including an actuating disc, at least one flexible rotating element, a dial, and a displacement adjusting element. The actuation disk is disposed on the base, and the actuation disk has a first disk surface, a second disk surface, and at least one through hole. The flexible rotating element is placed in the through hole and protrudes from the first disk surface and the second disk surface, and is rotatable within the through hole. The turntable is disposed opposite to the first disk surface of the actuating disk, and the turntable and the portions of the soft rotating member projecting the first disk surface are in contact with each other. The displacement adjusting component has an adjusting member and a fixing member which are relatively movable or relatively positioned. The actuating disc and the rotating disc are disposed between the adjusting member and the fixing member, and the adjusting member passes through the actuating disc and the rotating disc, and the adjusting member is opposite to the fixing member. The adjustment of the position causes the soft rotating element to generate friction with the turntable or does not generate friction.

The pivoting mechanism may further include at least one limiting disc and a fixing wall on the base, the limiting disc is disposed between the actuating disc and the fixed wall opposite to the second disc surface of the actuating disc, and the limiting disc There is a third disk surface and a fourth disk surface, wherein the third disk surface is opposite to the second disk surface of the actuation disk. Through the adjustment of the displacement adjusting component, the limiting disc can be moved toward the actuating disc to contact, squeeze the soft rotating component to generate friction and resistance, or move the limiting disc away from the actuating disc, and the limiting disc is moved. There is no distance between the soft rotating elements and no friction or resistance.

The pivoting mechanism described above may further include at least one sleeve and at least one positioning post. The sleeve is disposed on the fixed wall of the base and opposite to the fourth disk surface of the limiting plate. The positioning post is disposed on the fourth surface of the limit plate and sleeved into the sleeve. In other applications, the sleeve may be disposed on the limiting plate, and the positioning post is disposed on the fixed wall of the base relative to the limiting plate. Wherein, when the limit plate moves away from the actuating plate, the positioning post moves relative to the sleeve within the sleeve.

The pivoting mechanism further includes an elastic member disposed between the limiting plate and the fixed wall to provide a limit plate restoring force when the limiting plate moves relative to the actuating plate. For example, the elastic element can be a spring.

The present invention also provides a support frame using the above-mentioned pivoting mechanism, which comprises the above-mentioned pivoting mechanism and a bearing seat, and the pivoting mechanism is pivotally connected between the base and the carrier provided with the pivoting mechanism, wherein the pivot The rotating mechanism is configured to drive the base of the bearing relative to the pivoting mechanism to rotate, or through the displacement adjusting component of the pivoting mechanism, so that some soft rotating elements of the pivoting mechanism generate friction with the turntable in the pivoting mechanism to achieve locking.

The pivoting mechanism of the present invention or the support frame thereof is used to lock the rotation of the turntable by the friction force applied to the flexible rotating member by the turntable or the limit plate to fix the inclination angle of the carrier relative to the base. Due to the flexibility of the flexible rotating element, Sexual components are less prone to wear and therefore have a longer service life. In addition, when the turntable or the limit plate is away from the actuating plate and does not contact the soft rotating element or is not affected by the frictional force thereof, the turntable can drive the bearing seat to rotate without a segment, so the user can adjust the bearing seat according to actual needs. The angle of inclination of the base.

In view of the above, the actuation plate 210 has a first disk surface 212, a second disk surface 214, and a plurality of through holes 216. The through holes 216 extend through the first disk surface 212 and the second disk surface 214, and the flexible rotating element 220 can be inserted or fitted into the through holes 216 by telescopic pins or the like, and protrudes from the first disk surface 212 and the second disk surface. 214, These soft rotating elements 220 can also be designed to rotate within the through holes 216 in some applications. These soft rotating elements 220 are, for example, cylindrical rollers or spherical balls. Moreover, the material of the flexible rotating member 220 is, for example, rubber or plastic.

The turntable 230 is coupled to the carrier 400 and is disposed relative to the first disk surface 212 of the actuator disk 210. The turntable 230 and the carrier 400 are, for example, integrally formed, but the invention is not limited thereto.

The limit plate 240 is disposed between the actuation plate 210 and the fixed wall 310 of the base 300. The limit plate 240 has a third disk surface 242 and a fourth disk surface 244, wherein the third disk surface 242 is a second disk surface 214 relative to the actuation disk 210.

The displacement adjusting component 250 is configured to drive the turntable 230 and/or the limit plate 240 to move relative to the actuating disk 210. The displacement adjusting member 250 is composed of a fixing member 252 and an adjusting member 254, wherein one end of the fixing member 252 can be fixed to the fixing wall 310 of the base 300, and the adjusting member 254 is disposed on the outer side of the turntable to sequentially pass the turntable 230. The disk 210 and the limiting plate 240 are finally disposed on the other end of the fixing member 252. The adjusting member 254 is sleeved on the fixing member 252, for example, in a screwing manner, that is, the adjusting member 254 is moved relative to the fixing member 252 by a screwing manner to relatively actuate the turntable 230 and/or the limiting plate 240. The disk 210 is moved to determine whether the soft rotating member 220 on the actuating disk 210 is pressed to generate friction.

In order to make the present invention more familiar with the present invention, a method of adjusting the angle of the support frame 100 will be described below by way of example.

3A is a partial schematic view showing the support frame in a locked state according to an embodiment of the present invention, and FIG. 3B is a partial schematic view showing the support frame in an adjustable state according to an embodiment of the present invention. Referring to FIG. 3A and FIG. 3B simultaneously, since the support frame 100 is moved from the state of FIG. 3A to FIG. 3B, the position of some components may be changed. Therefore, the component to be changed is preceded by a lowercase English letter, such as a limit plate 240a, a sleeve 260a, and an elastic member 280a.

Referring to FIG. 2 and FIG. 3A, when the displacement adjusting member 250 is adjusted to move the limiting plate 240 toward the actuating plate 210, the soft rotating member 220 on the actuating plate 210 is pressed and frictional, and the frictional force will make the softness The rotating member 220 cannot rotate in the through hole 216 to assume a stationary state. Indirectly, the turntable 230 is also affected by the frictional force of the flexible rotating member 220 and cannot rotate relative to the actuating plate 210, so that the turntable 230 can be locked to maintain the bearing. The angle of rotation of the seat 400.

Referring to FIG. 2 to FIG. 3B simultaneously, if the angle between the bearing base 400 and the base 300 is to be adjusted, the displacement adjusting member 250 can be adjusted to move the limiting plate 240 away from the actuation plate 210, and the limit is limited. The disk 240a is spaced apart from the flexible rotating element 220 such that the flexible rotating element 220 is rotatable without being pressed, so that the turntable 230 can be rotated relative to the actuating disk 210, and the carrier 400 can be moved to change its relative to the base 300. slope.

In detail, when the rotation adjusting member 254 urges the sleeve portion edge of the adjusting member 254 against the third disk surface 242 of the limiting plate 240 to push the limiting plate 240, the limiting plate 240 is subjected to the adjusting member 254. The force of the force moves away from the actuating disc 210 to reach the position of the limit plate 240a of FIG. 3B, so as to have a space with the soft rotating element 220 on the actuating disc 210, so as to facilitate the relative rotation of the turntable 230. 210 turns.

In this embodiment, the pivoting mechanism 200 may further include a resilient member 280 disposed between the limiting plate 240 and the fixed wall 310 of the base 300. The elastic element 280 is, for example, a compression spring. When the sleeve portion of the adjusting member 254 abuts against the limiting plate 240 and moves away from the driving plate 210 by a distance to reach the position of the limiting plate 240a as shown in FIG. 3B, the elastic member 280a is compressed and stored elastically. Resilience. Therefore, when the adjusting member 254 moves away from the limiting plate 240, the elastic restoring force released by the elastic member 280a pushes the limiting plate 240a toward the actuating plate 210, so that the third disk surface 242 of the limiting plate 240 contacts the softness. The rotating member 220 is returned to the position shown in FIG. 3A to lock the rotation of the turntable 230.

In addition, in order to prevent the limit plate 240 from being subjected to the force applied by the adjusting member 254, it may rotate due to uneven force. In this embodiment, for example, at least one positioning is provided on the fixed wall 310 of the base 300. The sleeve 270 is disposed on the fourth disk surface 244 of the limiting plate 240 at the same time. That is, when the limiting discs 240a, 240 are moved toward or away from the actuating disc 210, the sleeves 260a, 260 are moved relative to the positioning post 270, thereby preventing the limiting disc 240 from rotating due to uneven force.

The fixing wall 310 of FIGS. 2, 3A and 3B is, for example, three positioning posts 270, and the fourth disk surface 244 of the limiting disk 240 is provided with corresponding three sleeves 260, but it is not intended to limit the present invention. . Those skilled in the art can determine the number of positioning posts 270 and sleeves 260 according to actual needs.

In addition, in this embodiment, the positioning post 270 is disposed on the fixed wall 310 of the base 300, and the sleeve 260 is disposed on the fourth disk surface 244 of the limiting plate 240. In other embodiments, the sleeve 260 and the positioning post 270 are interchangeable, that is, the positioning post 270 is disposed on the fourth disk surface 244 of the limiting plate 240, and the sleeve 260 is disposed on the fixed wall 310 of the base 300. on.

Please refer to FIG. 4 , which is a simplified mechanism and can save the cost of parts. The displacement adjusting component 250 of this embodiment is composed of a fixing member 252 and an adjusting member 254 without a sleeve. Specifically, the embodiment The adjusting member is, for example, a screw having a head, and the head has a hexagonal or polygonal shape to suit the rotation of the hand or the hex wrench, the multi-angle wrench to rotate, or the head has a concave shape. Or the cross-shaped groove is rotated by a slotted screwdriver or a Phillips screwdriver; and the fixing member 452 is, for example, a nut, and at the same time, depending on the requirement, whether the second disk surface 214 of the actuation disk 210 is designed to cooperate with the nut shape or Fit the groove or protrusion.

When the adjustment adjusting member 454 and the fixing member 452 are moved toward each other, the actuating disc 210 and the rotating disc 230 abut against each other or even the soft rotating member 220, thereby generating a frictional force to prevent the rotating disc 230 from rotating to achieve the locking effect.

When the angle of the carrier 400 needs to be adjusted, the adjustment adjusting member 454 and the fixing member 452 are away from each other, so that the flexible rotating member 220 can be freely rotated. At this time, the rotating plate 230 can be freely rotated to perform the segmentless angle adjustment without being subjected to friction. After the determined angle is adjusted, the adjustment member 454 and the fixing member 452 are pressed against each other or the soft rotating member 220 is pressed to achieve the purpose of positioning and locking.

In summary, the support frame of the present invention locks the rotation of the turntable by the friction force applied to the flexible rotating member by the limit plate to fix the tilt angle of the carrier relative to the base. Moreover, since the flexible rotating element has flexibility, it is less prone to wear than the rigid element. In addition, when the limit plate is away from the actuating plate and does not contact the soft rotating member, the turntable can drive the carrier to rotate without a segment, so that the user can arbitrarily adjust the tilt angle of the carrier relative to the base according to actual needs. It can be seen that the invention can not only effectively extend the service life of the pivoting mechanism, but also greatly improve the flexibility in angle adjustment.
