Description

Support device

This case relates to a supporting device, and more particularly to a supporting device for supporting at least one electronic device on an object.

According to the display device, a support device can usually stand firmly on an object, such as a table or a platform. The conventional support frame is a fixed form, and the user cannot adjust the height of the display device box to the object. Position, not to mention a supporting device capable of moving relative to the object in a three-degree space according to the use state of the user.

For example, the “screen support cantilever structure” of the national patent publication No. M305524, the screen support cantilever structure includes a clamp seat, a rotating arm, a support arm, a shaft joint seat, a connecting rod and a swing seat. For use, the supported object is supported and suspended by a support cantilever structure composed of a clamp seat, a rotating arm, a support arm, a shaft joint seat, a connecting rod and a swing seat. The pivot joint can provide the rotation of the tilt angle of the support arm, and the elastic element provides a certain elastic force, and the support arm can form a downward pull force to share the weight of the supported object. Support assist function can balance the weight of the LCD screen to achieve a smooth support effect.

In this case, the force of pulling the elastic element is changed through the guide groove, and the reaction force of the elastic element is used to share the weight of the supported object. However, the biggest problem with this technique is that it cannot arbitrarily adjust the swing of the support arm. Because the strength of the elastic element cannot be adjusted according to the status quo of implementation, it will limit the matching load device, such as the weight of the display device. After the support arm of the case is connected to the load device, it is still necessary to rely on the user to give a force, or adjust the support arm to a preset height by supporting or pressing down, and then use the lock attachment to achieve positioning in a tight manner to secure the support.

As shown in FIGS. 1 to 7, basically, the supporting device of the present case includes a clamp base 1, an extension arm 2, a support arm 3, and a back frame 4.

Please refer to FIG. 1 and FIG. 2, the clip base 1 is detachably assembled on an object, such as a table or a platform (not shown in the conventional art). The extension arm 2 is pivotally connected to the clamp base 1, so that the extension arm 2 has a first pivoting degree of freedom relative to the clamp base 1. The support arm 3 is pivotally connected to the extension arm 2, so that the support arm 3 has a second pivoting degree of freedom relative to the extension arm 2. The back frame 4 is pivotally connected to the support arm 3, so that the back frame 4 is relative to the support arm. 3 has a third pivoting degree of freedom. The supported object, such as a display device (not shown), is attached to the back frame 4. The first pivotal degree of freedom, the second pivotal degree of freedom, and the third pivotal degree of freedom can be overlapped or combined with each other without any interference, so the user can drive any component, and That is, any one of the extension arm 2, the support arm 3, and the back frame 4 allows the display device to select one of the first, second, and second pivotal degrees of freedom. At least one of them moves relative to the object.

Please refer to FIGS. 3 and 4. The clamp base 1 includes an inverted L-shaped carrier plate 11. A side wall 111 of the carrier plate 11 is connected to a top wall 112 at intervals, for example, a bottom plate 12 is screwed to the bottom plate. 12 longitudinally screwed at least one pressing member 121. A top cover 13 is further connected above the top wall 112. The top cover 13 and the abutment surface of the extension arm 2 are provided with a first pivoting mechanism, such as a pivot hole 131 and a pivot 21, and the pivot 21 is inserted. Receiving in the pivot hole 131, the extension arm 2 and the clamp base 1 use the first pivoting mechanism to make the extension arm 2 have a first degree of freedom of rotation relative to the clamp base 1.

The top wall 112 and the bottom plate 12 further include a reinforcing plate 14 that is also inverted L-shaped and is connected to the top wall 112 and the side wall 111. The reinforcing plate 14 can increase the overall thickness of the carrier plate 11 and Structural stress, so the at least one pressing member 121 is rotated and forced to be clamped to the object, which will not cause deformation of the bending angle position of the clamp seat 1, thereby increasing the extension arm 2, the support arm 3, and The display device attached to the back frame 4 is stable without shaking or falling.

Furthermore, in order to avoid damage to the surface of the article during the clamping process, the bottom surface of the reinforcing plate 14 is provided with a cushion gasket 141 made of a high-molecular elastic material, such as rubber.

In particular, as mentioned above, the reinforcing plate 14 can increase the overall thickness and structural stress of the carrier plate 11, so the number of the pressing members 121 can be reduced. For example, only a single pressing member 121 is left. Rotate outside the pressing time, and avoid the situation of clamping instability that may be caused by the uneven pressing force of multiple pressing pieces.

Please refer to FIG. 1 to FIG. 3 again, the extension arm 2 is used to increase the height of the supporting device, and may have a first pivoting degree of freedom relative to the clamp base 1; and the support arm 3 is relative to the extension arm. 2 has a second pivoting degree of freedom. Therefore, a second pivotal connection is provided opposite to the abutting surface of the extension arm 2 and the support arm 3 Mechanisms, such as a pivot hole 22 and a pivot shaft 361, are inserted into the pivot hole 22, so that the support arm 3 has a second pivoting degree of freedom relative to the extension arm 2.

The bottom surface of the extension arm 2 is partitioned into two or more wire grooves 25 by at least one partition plate 24, and a bottom cover 23 forming an opening with both ends of the wire grooves 25 is connected to the bottom surface of the extension arm 2. Each of the wire grooves 25 can be used for a wire of a display device, such as a power line and a signal line, and has a cable management function.

Please refer to FIG. 1, FIG. 2, FIG. 5 to FIG. 6, the supporting arm 3 is provided with a third pivoting mechanism, such as a pivot hole 341 and a pivot shaft 411. 411 is inserted into the pivot hole 341 so that the back frame 4 has a third pivoting degree of freedom relative to the support arm 3.

The support arm 3 further includes an upper link 31, a lower link 32, a fixing member 33, a connecting member 34, and a force applying mechanism 35. The lower link 32 is disposed below the upper link 31. The fixing member 33 is U-shaped and is located behind the upper link 31 and the lower link 32. The fixing member 33 and the upper link 31 are pivotally connected through a first upper shaft 311, and the fixing member 33 and the lower link 32 are pivotally connected through a first lower shaft 321. The connecting member 34 is located at the front side of the upper link 31 and the lower link 32 and is pivotally connected to the back frame 4. The connecting member 34 and the upper link 31 are pivotally connected through a second upper shaft 312, and The connecting member 34 and the lower link 32 are pivotally connected through a second lower shaft 322, so that the upper link 31, the lower link 32, the fixing member 33 and the connecting member 34 together constitute a Four-link mechanism. Wherein, the gravity F generated by the total weight of the display device (not shown) and the support arm 3 will generate a gravity torque T1 to the fixing member 33 (for example, FIG. 6 shows the gravity torque T1 in the counterclockwise direction).

The force applying mechanism 35 includes a set of tubes 351, a blocking piece 352 and a telescopic spring 353 provided in the sleeve 351, and is rotatably pivotally connected to the fixing member 33 and located on the first upper shaft 311 and the first A main shaft 354 between the lower shaft 321 passes through the main shaft 354, the bottom of the sleeve 351 and the telescopic spring 353 and is screwed to an adjusting screw 355 of the blocking piece 352, and pivots the front end of the sleeve 351 A positioning shaft 356 is connected to the front side of the lower link 32.

The sectional view of the force applying mechanism 35 after assembly is shown in FIG. 6. The connecting member 34, the upper link 31 and the lower link 32 can drive the sleeve 351 and the adjusting screw 355 to rotate relative to the fixing member 33. The front end of the sleeve 351 is pivotally connected to the lower link 32 and can be displaced with the lower link 32, and the two ends of the telescopic spring 353 abut against the blocking piece 352 and the inner wall of the rear end of the sleeve 351, respectively. So it can change as the sleeve 351 moves The degree of elastic deformation. Therefore, the elastic force of the telescopic spring 353 will generate a compensation torque T2 (shown in FIG. 6) on the fixing member 33. The direction of the compensation torque T2 is opposite to the direction of the gravity torque T1 to resist the gravity torque T1, thereby, This allows the user to conveniently apply force to pull the display device to adjust and position the display device at an arbitrary height position through the rotation of the support arm 3. To take a specific example, looking at one of the nodes, the gravity F of this embodiment will generate the gravity torque T1 to the first lower shaft 321, and the elastic force of the telescopic spring 353 will cause the first lower shaft 321 This compensation torque T2 is generated.

Please refer to FIG. 5 and FIG. 6 again. The longitudinal section of the upper link 31 is U-shaped, and the longitudinal section of the lower link 32 is U-shaped. The upper link 3 and the two ends of the lower link 32 After being pivotally connected to the fixing member 33 and the connecting member 34, the upper link 31 and the lower link 32 jointly define an accommodating space 323 for accommodating the force applying mechanism 35. The connecting member 34 includes a pivot hole 341 for pivoting the hanger 4, wherein an upper end of the connecting member 34 is pivotally connected to the upper link 31 through the second upper shaft 312, and a lower end of the connecting member 34 passes through the first The two lower shafts 322 are pivotally connected to the lower link 32.

The fixing member 33 is sleeved in an arm base 36 which is also U-shaped, and the fixing member 33 is covered with the arm seat 36 to increase the aesthetics, and the bottom of the arm seat 36 is extended and inserted in the longitudinal direction. The pivot shaft 361 in the pivot hole 22 of the extension arm 2 is extended.

In addition, in order to cover the upper link 31 and the lower link 32, an inverted U-shaped protective cover 37 is connected outside the upper link 31 and the lower link 32 to increase the number of the support arm 3. Beauty.

Furthermore, in order to prevent the telescopic spring 353 from interfering with the adjusting screw 355 during the telescopic process, the telescopic spring 353 is sleeved with a relay tube 38 for the adjusting screw 355 to pass through. In addition, in order to avoid deformation of the fixing member 33, the first upper shaft 311 and the first lower shaft 321 respectively pass through an abutting tube 331 capable of abutting both side walls of the fixing member 33.

In particular, in order to increase the structural strength of the two side walls of the fixing member 33, the first upper shaft 311, the main shaft 354, and the first lower shaft 321 are respectively connected to the outside of the two side walls. Each of the reinforcing side plates 332 uses at least two mortises 333 on both sides to be respectively inserted into a socket 334 corresponding to the two side walls, so that the two reinforcing side plates 332 are connected to the fixing member 33. Outside both sides.

When the connecting member 34, the upper link 31 and the lower link 32 rotate around the first upper shaft 311 and the first lower shaft 321 relative to the fixing member 33, the sleeve 351 will follow the lower Link 32 moves so that The retractable spring 353 can be lengthened or shortened by the force of the inner wall of the rear end of the sleeve 351 to change the compensation torque T2.

As shown in FIGS. 7 and 8, after the user lowers the height of the front end of the support arm 3, the adjustment screw 355 whose rear end is located in the fixing member 33 is exposed. At this time, the user can use a tool such as an internal The hexagonal wrench is inserted into a plug hole 355a at the rear end of the adjustment screw 355 and rotated to move the blocking piece 352 along the adjustment screw 355 to change the length of the telescopic spring 353, such as compressing the adjustment screw 355 or releasing the adjustment Screw 355 in order to adjust the compensation torque T2.

If the elastic force of the telescopic spring is not adjusted, when the height of the front end of the support arm 3 is reduced, in order to effectively resist the gravity torque T1, the sleeve 351 of the force applying mechanism 35 moves with the lower link 32, so that The telescoping spring 353 can be appropriately shortened due to compression under the force of the inner wall of the rear end of the sleeve 351 to change the compensation torque T2. Thereby, the telescopic spring 353 can generate a large elastic force to generate a large compensation torque T2 to the first lower shaft 321 to resist the gravity torque T1.

Please refer to FIG. 9, which shows a first embodiment of the back frame 4. The back frame 4 includes a pivot base 41. The pivot base 41 has a pivot shaft pivotally connected to the pivot hole 341 at the front end of the support arm 3. 411, which is used to be connected to a pendant 42 mounted on the pivot base 41, and pivoted in front of the pendant 42 and can be adjusted and rotated with respect to the pendant 42 and conforms to the VESA (Video Electronics Standards Association, Video Electronics Standards Association) ) Standard one mounting member 43. The mounting member 43 is used for mounting the display device. Therefore, after the back frame 4 is assembled, the third pivoting mechanism of the abutting surface of the support arm 3 and the back frame 4 is used, for example, the pivot shaft 411 is inserted into the pivot hole 341, so that the back frame 4 faces each other. The support arm 3 has a third pivoting degree of freedom.

As shown in FIG. 10 to FIG. 12, it shows another embodiment of the back frame 4, and the same reference numerals (symbols) are used to indicate the same components. Since the two embodiments of the back frame 4 share many common components, Only the differences between the two will be explained in detail later. A transverse bracket 44 is provided in front of the pivot joint 41. The transverse bracket 44 includes a multi-directional joint 441 connected to the front of the pivot joint 41. Each side of the multi-directional joint 441 is connected with a support rod 442. A pair of guide grooves 442a are symmetrically recessed on the front and rear sides of the support rod 442, and one end cover 442b is freely connected to the outside of each support rod 442.

Wherein, each of the supporting rods 442 is provided for bridging and sliding of at least one pendant 42, so a pair of protruding rails 421 are inserted into the pair of guide grooves 442 a on the inner wall of each pendant 42 so that each pendant 42 utilizes the pair of projections. The rail 421 slides laterally and linearly along the pair of guide grooves 442 a of each support rod 442. The front of each pendant 42 is pivotally connected to a mounting member 43 that can be adjusted and rotated with respect to the pendant 42 and conforms to the VESA standard, and the mounting member 43 is used for mounting the display device D.

In order to be able to adjust the left and right inclination angle of the lateral bracket 44 with respect to the pivot base 41, a pivot post 412 is protruded in front of the pivot mount 41, and at least two fan-shaped tenons 413 are protruded in the rear peripheral surface of the pivot post 412. At least two fixing grooves 414 are recessed in the front peripheral surface of the shaft post 412. A first-stage shaft hole 441a for the shaft post 412 to pass through is provided behind the multi-directional joint 441, and the rear peripheral surface of the shaft hole 441a is connected with a slightly larger size, the same shape, and is provided for the sector-shaped tenons 413. At least two fan-shaped tongue and groove 441b.

A friction washer 441c is provided between the fan-shaped tongue grooves 441b and the fan-shaped tongues 413 for the fan-shaped tongues 413 to pass through. In front of the shaft hole 441a, a positioning washer 441d protruding at least two fixing tenons 441e and at least one elastic body 441f, such as a disk spring or a spring, are sequentially inserted into the rear peripheral surface. After the elastic body 441f and the positioning washer 441d are screwed to the shaft post 412, the fixing tenons 441e are inserted into the fixing grooves 414, so that the positioning washer 441d cannot be rotated, and the shaft post 412 is added The multi-directional joint 441 can be firmly positioned in front of the pivot joint 41. Finally, a decorative cover 441h is installed in front of the shaft hole 441a, so that the shaft hole 441a is closed to increase the visual beauty.

As shown in FIG. 12, if the weights of the display devices D carried by the two supporting rods 442 are different, the stopper action of the fan-shaped grooves 441 b and the fan-shaped tongues 413 makes the heavier load. The support rod 442 will be slightly inclined. At this time, the locking member 441g only needs to be loosened slightly to release the urging mode, and the opposite support force is applied to the support rod 442 on the other side to make the two support rods 442. After the level is formed, the locking member 441g is further locked to complete the level adjustment of the two supporting rods 442.

In particular, in order to easily control the lifting and lowering of the horizontal bracket 44, a handle 443 is connected to the bottom of the multi-directional joint 441 to facilitate the operation of the user.

As shown in FIG. 13 to FIG. 14, it shows a second embodiment of the supporting device. Compared with the first embodiment, the same reference numerals (symbols) are used to represent the same components. Since this embodiment shares many common components with this first embodiment, only the differences between the two will be described in detail later.

The difference between this second embodiment and the first embodiment is that it omits the setting of the extension arm 2, that is, a pivoting mechanism is provided opposite to the abutting surface of the base 1 and the support arm 3, such as a pivot hole 131 and A pivot shaft 361 is inserted into the pivot hole 131, so that the support arm 3 has a first pivoting degree of freedom relative to the base 1.

The two previous embodiments of the back frame 4 can be applied to the second embodiment, and the back frame 4 and the support arm 3 use another pivoting mechanism, such as a pivot hole 341 and a pivot 411, The pivot shaft 411 is inserted into the pivot hole 341, so that the back frame 4 has a second pivoting degree of freedom relative to the support arm 3.

Therefore, through the implementation of this case, the effect obtained is that the force applying mechanism in the four-link mechanism of the support arm can provide compensation torque to resist the gravity torque generated by at least one display device at different height positions. The height of the at least one display device can be adjusted up and down to achieve the effect of forming stagnation and positioning at any height. In particular, in addition to the reinforced design of the clamp seat, in addition to increasing stability, it can effectively reduce the number of pressing members, and it is not easy to cause the support arm and the at least one display device to fall over. In particular, by adopting a common modular structure design for some components of the back frame, only the simple disassembly and replacement of the pivot base or the pivot base and the horizontal bracket can be performed to enable the support device. Connecting a single display device or connecting two display devices can help increase the range of use of the support device, which is a great structure that has never been seen in similar articles.

The one disclosed in this case is one of the preferred embodiments, and any change or modification that originates from the technical ideas of this case and is easily inferred by those who are familiar with the technology, does not depart from the scope of patent rights in this case.
