Supporting device capable of switching bearing capacity

The present invention relates to a support device capable of switching load bearing capacity; in particular, a support device having a hinge capable of adjusting its bearing capacity in multiple stages.

Taiwan Patent No. M476873 discloses a hinge and display support device. The hinge includes a shaft, a carrier, a buckle, a first torsion spring and a second torsion spring. The carrier is pivotally mounted on the shaft and is rotatable relative to the shaft to change between a first state and a second state; the buckle is fixed to the shaft. A first end and a second end of the first torsion spring are respectively fixed to the carrier and the buckle, and a third end of the second torsion spring is fixed to the carrier. And the fourth end of the second torsion spring abuts the buckle in the first state, and is detached from the buckle in the second state, and determines the second by controlling whether the second torsion spring abuts the buckle Whether the torsion spring provides torque to change the overall support force. In other words, in addition to the first torsion spring can continue to provide the torsion, the second torsion spring depends on the rotation angle of the shaft and the carrier. When rotating within a certain angle, the fourth end of the second torsion spring is abutted. The buckle can be used to provide the torsion force. In this case, it is in the first state, and when it is rotated outside the certain angle, the fourth end of the second torsion spring is disengaged from the buckle without providing a torque, and is in the second state.

However, the conventional support device has the disadvantage that it must rely on the buckle and the second twist. The relative position of the spring can determine whether it is the first state or the second state. That is to say, if the user wants to control the second torsion spring to provide the torsion, the support device can only be rotated to a certain angle or more, so that the second torsion spring can abut the second ring. Actuate. However, the angle is limited by the structural design of the buckle and the second torsion spring, so the user cannot decide whether the second torsion spring is activated or not according to the use condition, and may not meet the actual demand.

In view of this, a supporting device capable of switching load capacity is provided, which is suitable for mounting display modules of different weights, and is convenient for the user to adjust and operate, and is highly demanded in the industry.

One object of the present invention is to provide a support device capable of switching the tensile force, which has a plurality of torsion spring sets to achieve a multi-stage structural adjustment design, and the user can easily adjust the bearing capacity to match the electronic device or Display the weight of the module and choose the appropriate load capacity.

To achieve the above object, the present invention provides a support device capable of switching load carrying capacity, the support device comprising a bracket structure, a connecting member and a first hinge. The first hinge pivotally connects the bracket structure and the connecting member.

The first hinge includes a mandrel member, a first torsion spring set and a second torsion spring set. The mandrel member is disposed on the connecting member and has a non-circular cross section, and defines a first portion and a second portion along an axial direction. The first torsion spring group has a first torsion spring, and is sleeved on the connecting portion. In the first part, the second torsion spring group has a second torsion spring and a button respectively sleeved on the second portion. Wherein, the button can be changed between the first position and the second position along the axial direction. When the button is in the second position, and the connecting member pivots relative to the bracket structure to drive the spindle member to rotate, the spindle member drives the first torsion spring group to rotate, so that the first torsion spring Being reversed to produce a first a torque; when the first button is driven to move from the second position to the first position along the axial direction, and the connecting member pivots relative to the bracket structure to drive the spindle member to rotate, the first The torsion spring is twisted to correspondingly generate the first torsion and actuate the second torsion spring to a state that can be twisted to generate a second torsion.

The second shaft hole 21 is bored by the mandrel member 31, so that when the connecting member 2 is rotated, the mandrel member 31 can be simultaneously rotated, and the left half of the second drawing corresponds to The structure of the second hinge 4 is the same as that of the first hinge 3, and will not be further described herein. At this time, since the bearing member 5 is interlocked with the connecting member 2, the bearing member 5 also rotates with the connecting member 2.

Further explaining the first torsion spring group 32 of the first hinge 3, please refer to FIG. 2A and FIG. 2B and 2C, the first torsion spring group 32 is located between the tubes 12, and the first torsion spring group 32 has a The first torsion spring 320 and a fixing member 321 . The first torsion spring 320 and the fixing member 321 are sleeved on the first portion 31a of the mandrel member 31. The fixing member 321 has a third shaft hole 321b. The shape of the third shaft hole 321b corresponds to the non-circular cross section of the mandrel member 31. That is to say, when the spindle member 31 rotates, the fixing member 321 can be rotated. The first torsion spring 320 has a first end portion 320a and a second end portion 320b respectively fixed to a fixing groove 321a of the fixing member 321 and a fixing hole 12a of the tube body 12. Therefore, when the user adjusts the display module fixed on the bearing member 5, the bearing member 5 drives the connecting member 2 to rotate, thereby interlocking the mandrel member 31 and the fixing member 321 due to the first torsion spring 320 The one end portion 320a is disposed on the fixing member 321, so that the first torsion spring 320 can provide a torsion force. Similarly, the related structure and operation manner of the second hinge 4 are the same as those of the first hinge 3, and therefore will not be further described.

Next, the detailed structure of the second torsion spring group 33 of the first hinge 3 will be described, please Referring to FIGS. 4, 5, and 6, the second torsion spring set 33 is sleeved on the second portion 31b of the mandrel member 31 and received in the tubular body 12. The second torsion spring set 33 has a second torsion spring 330, a button 331, a latching member 332, an elastic member 333, a triggering structure 334 and a latch 335. The second torsion spring 330 has a third end portion 330a and a fourth end portion 330b. The button 331 has a cover body 3310 and a cover member 3311. The cassette 335 is disposed on the cover body 3310 and the cover body fitting member 3311. It is fixed to the mandrel member 31. The latch member 332 has an accommodation space 332a and a plurality of card ends 332b. The triggering structure 334 has a triggering member 3341 and a fitting member 3342. The triggering member 3341 defines a first shaft hole 334a and a plurality of channels 334b corresponding to the non-circular cross section of the spindle member 31. The fitting member 3342 is formed with a plurality of The first slot 334c, a protrusion 334d, a second slot 334e and a fifth shaft hole 334f, in particular, the fifth shaft hole 334f has a circular shape and is not a non-circular cross section.

The latching member 332 is in contact with the button 331 and the elastic member 333 is accommodated therein. In the space 332a, the triggering member 3341 of the triggering structure 334 abuts against the elastic member 333, and the second torsion spring 330 The fourth end portion 330b is sleeved in a fourth slot 12b of the inner wall of the tube body 12, and the third end portion 330a is selectively abutted against the second slot 334e of the triggering structure 334. The cover 3310 is engaged with the cover fitting 3311. In more detail, the Incarcer 335 has a shaft hole corresponding to the non-circular cross section of the mandrel member 31, and can be positioned by, for example, a nut 336 so that the cassette 335 can be positioned on the mandrel member 31. Fixed location.

Next, the operation mode of the second torsion spring group 33 will be described in detail, wherein The left half of the 2C diagram shows the state in which the button 331 of the second torsion spring group 33 is not pressed, and the right half shows the state in which the button 331 of the second torsion spring group 33 is pressed, so the following description The two states of action can be compared with the details shown on the left and right sides of Figure 2C.

First, the state in which the button 331 is not pressed is explained. At this time, the cassette 335 is engaged with the cover. The first inner groove 331a of the engaging member 3311, the latching end 332b of the latching member 332 is away from the first latching groove 334c of the triggering structure 334, and only the channel 334b on the triggering member 3341 The fifth shaft hole 334f on the fitting member 3342 is circular. Therefore, when the spindle member 31 drives the trigger member 3341 to rotate, the fitting member 3342 is not locked, and does not rotate with the spindle member 31. The third end portion 330a of the torsion spring 330 cannot abut against the second slot 334e of the triggering structure 334. In other words, the second torsion spring 330 cannot function to provide a torsion.

Further, when the button 331 is not pressed and is in a second position P2, only The first torsion spring 320 of the first torsion spring group 32 will function. That is, when the connecting member 2 is pivoted relative to the frame body 11 of the bracket structure 1 to drive the spindle member 31 to rotate, only the first torsion springs 320 are twisted to correspondingly generate a first torsion.

Next, a state in which the button 331 is pressed is explained, and when the button 331 is driven, the The axial direction D translates and rotates to a first position P1, at which time the second torsion spring 330 of the second torsion spring set 33 enters The twisted state can be actuated, and a second torque is generated correspondingly. More specifically, the latch 335 fixed to the spindle member 31 is originally engaged in the first inner groove 331a of the cover fitting 3311 when the button 331 is at the second position P2, and the button 331 is pressed and rotated. The process of the first position P1 is to first press the cover body 3310 to interlock the cover fitting 3311, so that the cover fitting 3311 and the cassette 335 are disengaged, and simultaneously rotate the cover 3310 and the cover relative to the cassette 335. After the engaging member 3311 is released to a certain angle, the second inner groove 331b of the cover fitting 3311 can be engaged with the latch 335. At this time, the cover 3310 and the cover fitting 3311 are located at the first position P1.

As can be seen from FIG. 6, the first inner groove 331a and the second inner groove 331b have a height. Poor, and because the cassette 335 is attached to the fixed position on the mandrel member 31, it is conceivable that when the cassette 335 is located in the second inner groove 331b, the button 331 will thus provide an axial thrust to the first portion 31a to push The latching member 332 compresses the elastic member 333, and the latching end 332b is engaged with the first latching slot 334c through the passage 334b, wherein a width of the latching end 332b is preferably slightly larger than the first latching slot 332b. A width of a card slot 334c can be clamped to each other to avoid loosening. Thereby, the third end portion 330a of the second torsion spring 330 is fixed in the second slot 334e of the triggering structure 334, in other words, both ends of the second torsion spring 330 are fixed and can be twisted. When the connecting member 2 is pivoted relative to the frame body 11 to drive the spindle member 31 to rotate, the spindle member 31 simultaneously drives the fixing member 321 and the triggering member 3341 of the triggering structure 334 to rotate, so that the first torsion spring 320 and the second portion are rotated. The torsion spring 330 is simultaneously twisted to generate a first torsion and a second torsion.

In particular, if the button 331 is to be pressed to the first position P1 The condition is removed, as well as pressing and rotating the button 331. In more detail, the cassette 335 fixed to the mandrel member 31 is engaged with the second inner groove 331b of the cover fitting 3311. The user first presses the cover 3310 to interlock the cover fitting 3311. Making the cover fitting 3311 and the cassette 335 Disengaged, and then released relative to the cassette 335 by rotating the cover body 3310 and the cover fitting 3311 to a certain angle, the elastic member 333 will urge the button 331 to be reset, so that the first inner groove 331a and the latch of the cover fitting 3311 When the 335 is engaged, the cover 3310 and the cover fitting 3311 are the second position P2. During this process, the third end portion 330a of the second torsion spring 330 will be disengaged from the second slot 334e and returned to the inactive state that could not be actuated to be twisted, so that the second torsion is not generated.

In addition, in other embodiments of the present invention, the number of the card end 332b, the channel 334b, and the first card slot 334c may be increased or decreased according to the situation, and details are not described herein.

The display module can be supported only by pressing the button 331 of the second hinge 4 to support a 12-inch 23-inch display module; while pressing the button 331 of the first hinge 3 and the second hinge 4 simultaneously, the size can be supported. Larger and heavier display modules. However, the torque of each of the first torsion springs 320 and the second torsion springs 330 is not limited thereto, and the number and torsional strength of the first torsion springs 320 and the second torsion springs 330 can be adjusted according to requirements.

In addition, in another embodiment of the present invention, a part of the first torsion spring group may be omitted. 32 configuration. Referring to FIG. 7, the first hinge 3 has a first torsion spring group 32 and a second torsion spring group 33, and the second hinge 4 includes only a second torsion spring group 33 to omit the first torsion spring group 32. Configuration. The mandrel member 31 of the first hinge 3 defines a third portion 31c along the axial direction D. The third portion 31c is located on one side of the first portion 31a and away from the second portion 31b, and the second twist of the second hinge 4 The spring set 33 is sleeved in the third portion 31c. In the present embodiment, only the first hinge 3 has the first torsion spring set 32, and the first torsion spring set of the second hinge 4 is omitted, that is, the entire support device 1000 is only provided with a first twist. The spring set 32, the user can respectively activate the first torsion spring group 32 of the first hinge 3 and the second torsion spring group 33 of the second hinge 4 by pressing a button, but the torsion spring can be adjusted according to requirements. The number of actuations and the overall torsional strength of the group to support display modules of different weights.

Alternatively, in another embodiment of the present creation, only the first hinge 3 may be retained. The second hinge 4 is omitted, that is to say, the support device 1000 is only provided with a hinge. In this way, the support device 1000 has only two-stage carrying capacity for switching, but the purpose of the present invention can still be achieved. Therefore, adjustments such as the increase or decrease of the number of the hinges, or the arrangement of the partial torsion spring groups in the hinge, etc., should be understood by those skilled in the art, which can be easily accomplished according to the contents disclosed in the present disclosure. Still belongs to the scope of this creation.

In summary, the second torsion spring group is obtained by driving the button structure. Relatively moving to different positioning, the torque of the torsion spring can be adjusted in multiple stages, and the user can adjust the bearing capacity of the supporting device according to the weight of the purchased display module, and even if the user replaces the display module of different weights It is only necessary to make corresponding adjustments through the button structure, and it is not necessary to re-purchase a suitable supporting device, and at the same time, the user can feel a better operating feel when creating the supporting device during operation.
