Description

Adjustable torque hinge and electronic device

technical field

The utility model relates to a hinge device with adjustable torque, in particular to a hinge device arranged between a display panel and a base of an electronic device so that the display panel can pivot relative to the base.

Background technique

The hinge is one of the indispensable components in the clamshell electronic device. It is installed between the base of the electronic device and the display panel. It uses different parts to fix the display panel and the base respectively, so that the display panel can be relatively The base pivots, and the relative rotation between these different components also relatively generates friction to form a torsion force, and the torsion force can make the display panel stagnate at any position, so that the user can adjust the desired viewing angle of the display panel.

However, the torque value of the hinge device in the prior art is set when each component is manufactured. For example, if the torque value is mainly output by the spring frame, the torque value is determined by parameters such as the material of the spring frame and the diameter of the pipe. ; Another example is that the torsion value is mainly output by the spring, and the torsion value is determined by parameters such as the elastic coefficient of the spring. Therefore, if you want to obtain a different torsion value, even if the same hinge is composed of components, the manufacturer still has to remake different keys. Only components with different torque values can be obtained; for example, if a hinge is also composed of a pivot and a pipe spring frame, as long as a different torque value is required, the pipe spring frame must be remade, which will cost more for the manufacturer. Much manufacturing cost.

Utility model content

In view of the above-mentioned shortcomings of the prior art, the utility model designs a hinge device with adjustable torque, so that users can adjust different torque values according to needs during assembly.

In order to achieve the purpose of the above-mentioned utility model, the technical means adopted in the utility model is to design a hinge device with adjustable torque, which includes:

a pivot;

a swivel bracket fixed to the pivot;

A torsion spring, which is sheathed outside the pivot and has an adjustment end and a fixed end;

A fixed support frame, which is fixed to the fixed end of the torsion spring, the fixed support frame has an accommodation plate, and the accommodation plate is opposite to the adjustment end of the torsion spring, and an adjustment hole is formed through the accommodation plate;

An adjustment piece, which runs through the adjustment hole of the accommodation plate of the fixed support frame, and the adjustment piece protrudes from the accommodation plate. The adjustment piece has a contact end, and the contact end pushes against the adjustment end of the torsion spring.

The swivel bracket 30 is sheathed and fixed outside the fixed rod 22 of the pivot shaft 20. The end surface of the swivel bracket 30 is concavely formed with a non-circular hole 31 to engage and fix the fixed rod 22, so the swivel bracket 30 is relatively When the fixed support frame 10 rotates, it will drive the pivot shaft 20 to rotate relative to the fixed support frame 10, and the end surface of the rotating support frame 30 is concavely formed with a limit arc groove 32, and the limit protrusion 115 of the fixed support frame 10 is penetrated on the rotating frame. In the limiting arc groove 32 of the bracket 30, when the rotating bracket 30 rotates relative to the fixed bracket 10, the limiting arc groove 32 and the limiting protrusion 115 rotate relative to each other, and pass through the end edge of the limiting arc groove 32. Pushing against the limiting protrusion 115 to limit the rotation angle of the swivel bracket 30 , a connecting wing 33 is radially extended from the outer wall of the swivel bracket 30 .

The torsion spring 40 is wound and sheathed outside the pivot shaft 20 and passed through the sleeve 11 of the fixed bracket 10 . The torsion spring 40 has an adjusting end 41 and a fixed end 42 . Placed on the board 113, the fixed end 42 and the fixed bracket 10 are fixed to each other.

Please refer to FIG. 5 , the adjustment member 50 passes through the adjustment hole 114 of the accommodation plate 113 and protrudes from the accommodation plate 113, the contact end 51 of the adjustment member 50 pushes the adjustment end 41 of the torsion spring 40, and the adjustment member 50 can be After being moved up and down in the adjustment hole 114 and positioned, it can be a screw hole relative to the adjustment hole 114 , and the adjustment member 50 can be screwed into the adjustment hole 114 by a screw.

Please refer to Fig. 6, the electronic device of the present invention includes a display panel 60, a base 70 and at least one hinge device 1 of the utility model, the hinge device 1 is located between the display panel 60 and the base 70, the hinge device 1 The connecting wing 33 of the rotating bracket 30 and the display panel 60 are fixed to each other, and the fixed wing 12 and the base 70 of the fixed bracket 10 of the hub 1 are fixed to each other. When the display panel 60 pivots relative to the base 70, the rotating bracket 30 rotates relative to the fixed bracket 10.

5 and 6, when the rotating bracket 30 rotates relative to the fixed bracket 10, the rotating bracket 30 drives the pivot 20 to rotate relative to the torsion spring 40, and the torsion spring 40 and the pivot 20 rotate Mutual friction produces torsion force, then the torsion force will make the display panel 60 stagnate at the viewing angle required by the user, and with the design of the winding direction of the torsion spring 40 and the rotation direction of the rotating bracket 30, when the display panel 60 is unfolded toward When the angle is rotated (taking FIG. 5 as an example, in the counterclockwise direction), the pivot 20 will loosen the torsion spring 40 to reduce the torsion force at this time, and when the display panel 60 rotates toward the closed angle (as shown in FIG. 5 For example, in the clockwise direction), the pivot 20 relatively tightens the torsion spring 40 to increase the torsion force at this time. Therefore, the hinge device 1 of the present utility model provides the characteristics of having different torsion values when rotating in different directions. In terms of this function, it is called "opening light and closing heavy", which allows the user to save effort when unfolding the display panel 60, and can quickly unfold the display panel 60 for use, but also allows the user to spend more force when closing the display panel. In order to protect the display panel 60 from being closed too quickly and accidentally colliding with the base 70 to cause damage.

Please refer to FIG. 5 and FIG. 7, when the manufacturer wants to change the torque value provided by the hinge 1, the purpose of adjusting the torque value can be achieved by changing the height of the adjustment member 50 protruding from the receiving plate 113;

When the height of the adjusting member 50 protruding from the receiving plate 113 is low (as shown in FIG. 5 ), the degree of tightness of the torsion spring 40 wrapped around the pivot 20 is relatively tight, so the friction between the pivot 20 and the pivot 20 is relatively small. Large, the torque value output by the hub 1 is also relatively large at this time. With the aforementioned function of opening light and closing weight, the torque value when unfolded in this state is about 2kg, and the torque value when closed is about 8kg;

When the height of the adjusting member 50 protruding from the accommodating plate 113 is high (as shown in FIG. 7 ), the lifting of the adjusting end 41 makes the degree of tightness of the torsion spring 40 wound around the pivot 20 looser. The frictional force between the pivots 20 becomes smaller, and the torque value output by the hinge 1 is also relatively small at this time. With the above-mentioned function of opening light and closing weight, the torque value when unfolding in this state is about 1.5 to 1.8kg , and the torque value when closing is about 4 to 7.5kg;

Therefore, in the case that all parts are the same, the effect of adjusting the torque value output by the hinge device 1 of the present invention can be achieved only by changing the position of the adjusting member 50 . It must be specially noted that the above torsion values are only for illustrative purposes only, and the hinge device 1 of the present invention can still achieve the function of switching the light and closing the weight no matter whether the adjusting member 50 is used or not.

Please refer to FIG. 8 to FIG. 10 which show another embodiment of the hinge device of the present invention, which further includes a pipe reed 80A, which is sleeved outside the pivot 20A and passed through the torsion spring 40A The wall of the pipe reed 80A is formed with a longitudinal notch 81A, so that the pipe reed 80A can be expanded or contracted. There is a corresponding card slot 116A concavely formed on the level surface, and the extension protrusion 82A of the pipe reed 80A is inserted into the card slot 116A of the fixed bracket 10A to fix the tube reed 80A and the fixed bracket 10A to each other. The ring flange 21A and the fixed rod 22A of the shaft 20A are respectively formed on opposite ends of the pivot shaft 20A, and the pipe reed 80A is relatively located between the rotating bracket 30A and the ring flange 21A, so the ring flange 21A can block the pipe reed 80A is axially disengaged from pivot 20A.

Please refer to FIG. 11 and FIG. 12 , when the manufacturer wants to change the torque value provided by the hinge device, the purpose of adjusting the torque value can also be achieved by changing the height of the adjustment member 50A protruding from the receiving plate 113A;

When the height of the adjusting member 50A protruding from the accommodation plate 113A is low (as shown in Figure 11), the degree of tightness of the torsion spring 40A wound around the outside of the pipe reed 80A is relatively tight, so that the pipe reed 80A is more tightly attached Leaning against the pivot 20A, so the friction between it and the pivot 20A is relatively large, and the torque value output by the pivot is relatively large at this time;

When the adjustment part 50A protrudes from the receiving plate 113A to a higher height (as shown in Figure 12), the adjustment end 41A is pushed up so that the torsion spring 40A is wound around the tube reed 80A loosely, and the tube reed 80A is loose. The strength of the reed 80A covering the outside of the pivot 20A is relatively small, and the longitudinal notch 81A is relatively open, so the friction between the reed 80A and the pivot 20A becomes smaller, and the torque value output by the hinge is relatively small at this time;

Therefore, in another embodiment of the hinge device of the present invention, when all parts are the same, only changing the position of the adjustment member 50A can achieve the adjustment of the output torque value.

In addition, it should be particularly noted that, in the first embodiment (as shown in FIGS. 1 and 2 ), the torsion spring 40 directly generates friction with the pivot shaft 20 , so when the display panel 60 is closed relative to the base 70 , the torsion spring 40 The degree of tightness wound around the pivot shaft 20 becomes tighter; conversely, when the display panel is turned on, the degree of tightness wound around the pivot shaft 20 by the torsion spring 40 becomes looser, thereby producing the function of turning light on and off. However, in the second embodiment, when the display panel 60 is opened or closed relative to the base 70, the friction between the pipe reed 80A and the pivot 20A will generate a torsion force, therefore, this torsion force will be a fixed value, Therefore, in this implementation, there is no so-called "open light and close heavy" function; that is, the torque force when the display panel 60 is opened or closed relative to the base 70 will be the same. However, since the torsion spring 40A directly exerts force on the pipe reed 80A, the torsion value can still be controlled by adjusting the height of the adjustment member 50A protruding from the accommodating plate 113A, but there will be no so-called " The function of "on light off and off heavy" is generated.

In addition, it should be specifically stated that in the first embodiment, the sleeve 11 is formed on the fixed bracket 10, and then the fixed end 42 of the torsion spring 40 is fixed in the sleeve 11; however, it can also be The fixing end 42 of the torsion spring 40 is directly fixed on the fixing bracket 10 by omitting the sleeve 11, which does not affect the efficacy of the present invention. Therefore, the fixing bracket can have various forms and is not limited to what is described in the present invention.

The above descriptions are only preferred embodiments of the present utility model, and do not limit the utility model in any form. Although the utility model has been disclosed as above with preferred embodiments, it is not intended to limit the utility model. Anyone in the field Skilled persons, within the scope of the technical solution of the utility model, should be able to use the technical content disclosed above to make some changes or modify equivalent embodiments with equivalent changes.
