According to an embodiment of the present invention, a display apparatus includes: a display main body for outputting an image; a stand device to which the display main body is rotatably connected; And an elastic member, one end of which moves in unison with the display body and the other end of which is connected to a point of the stand apparatus, to generate a rotation moment in a direction opposite to the tilting direction of the display body.

Description

Display device

This embodiment relates to a display device.

A display device is a device for viewing an image, and a lot of flat display devices having a very thin thickness have recently been released. These flat display devices are attracting much attention from consumers because of their small volume, light weight, and easy handling.

These display devices are wall-mounted and fixed to the wall, or may be placed on the floor by a stand device. This embodiment relates to a form in which the display device is placed on the bottom surface and supported.

In addition, when the display device is installed on the floor by the stand, the viewing angle of the screen should be easily adjustable by the user. In this case, in order to maintain the screen inclined rearward, a friction force of a certain size or more must be applied to the connection point of the display screen unit and the stand unit.

As the display screen becomes larger, the frictional force must be increased, and the thickness or width of the connection portion of the display screen unit and the stand unit must be increased to increase the frictional force.

However, according to the trend of slimming display devices, the thickness or width of the connection portion needs to be slimmed. As such, as the friction area formed on the connection portion decreases, a phenomenon in which the display screen is not kept inclined forward or backward may occur, and there is a need for improving such a phenomenon.

An object of the present embodiment is to propose a display device that reduces the friction area formed at the connection portion between the display screen portion and the stand portion, and keeps the display main body in a tilted state.

According to an aspect of the present invention, a display apparatus includes a display main body for outputting an image; A stand device to which the display main body is rotatably connected; And an elastic member, one end of which moves in unison with the display body and the other end of which is connected to a point of the stand apparatus, to generate a rotation moment in a direction opposite to the tilting direction of the display body.

According to another aspect of the present invention, a display apparatus includes a display main body; A stand device supporting the display main body; A hinge assembly configured to pivotally connect a lower end of the display body to the stand apparatus; A connection part extending downward from the lower end of the display main body to a length shorter than the length of the display main body; And an elastic member connecting the connection part and the stand to generate a rotation moment in a direction opposite to the tilting direction of the display main body.

According to the proposed embodiment, there is an advantage in that the friction force required for the hinge axis of rotation is reduced during tinting of the display main body.

In addition, the frictional force on the hinge rotation axis is reduced so that the user can tint the display body with a small force.

In addition, since the frictional force on the hinge rotation shaft is reduced, the space occupied by the hinge portion can be reduced, thereby ensuring space and reducing the constraints on the design. This has the advantage of producing a slim display device as a whole.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a display apparatus according to a first embodiment.

Referring to FIG. 1, the display apparatus 1 according to the first embodiment includes a display main body 2 for outputting an image or an image, and a display main body 2 coupled to a lower side of the display main body 2. Supporting stand apparatus 10 is included.

The display body 2 includes a front cabinet 4 forming a front exterior and a rear cabinet 6 (refer to FIG. 2) coupled to a rear side of the front cabinet 4 to form a rear exterior. The display module 5 is accommodated in the space between the front cabinet 4 and the rear cabinet 6.

Meanwhile, a hinge assembly 30 (see FIG. 3) is provided at a connection portion between the display main body 2 and the stand apparatus 10, so that the display main body 2 is moved forward or rearward from the stand apparatus 10. It is comprised so that predetermined angle rotation is possible. In addition, the display body 2 may be maintained in a tilted state by frictional force generated in the hinge assembly 30 (see FIG. 3).

2 is a cross-sectional view taken along the AA plane of FIG. 1, FIG. 3 is an exploded perspective view of the stand apparatus according to the first embodiment, and FIG. 4 is an enlarged state in which the connection member and the display main body are coupled according to the first embodiment. One drawing.

2 to 4, in the stand apparatus 10 according to the first embodiment, a base 12 placed on an installation surface and an upper surface of the base 12 are coupled to the stand apparatus 10. A weight body 13 coupled to the base 12 so that the stand body 11 forming an outer shape and the center of gravity of the display device 1 are formed at a point close to the bottom of the stand apparatus 10. Included.

In detail, the base 12 is in contact with the ground and forms the bottom surface of the display device 1. The base 12 is provided in a flat planar shape. For example, in the present embodiment, a circular flat planar shape is provided.

A support part 121 for supporting the weight member 13 is formed at the center of the base 12, and the support part 121 protrudes upward from the bottom surface of the base 12. In addition, the support part 121 is provided with a fastening hole 123 through which the fastening member 14 passes.

A depression 122 recessed upward from the bottom of the base 12 is formed. A fastening member 14 for inserting the weight member 13 into the base 12 is inserted into the recess 122. In addition, the recess 122 is recessed upward, to prevent the head portion of the fastening member 14 from interfering with the installation surface.

The weight member 13 is provided with a hole 131 through which the fastening member 14 passes. In addition, a plurality of through holes 132 may be formed at outer edges of the weight member 13. The fastening member 17 passes through the through hole 132 and is inserted into the fastening hole 16 formed on the bottom surface of the stand body 11. Since the weight member 13 should have a weight greater than or equal to a certain level, the weight member 13 may be made of a metal material having a high density.

The display body 2 is hinged to the stand body 11, and may be rotated by a predetermined angle in the front-rear direction while being connected to the stand body 11. A hollow portion 19 is formed inside the stand body 11, and the stand body 11 may be formed in a shape in which a cross sectional area decreases from an upper side to a lower side. In the first embodiment, the cross section of the stand body 11 is formed in a circular shape, but the shape of the stand body 11 is not limited thereto.

When the display main body 2 is tilted, no interference should occur between the display main body 2 and the stand body 11. Accordingly, there may exist a free space 11a between the display main body 2 and the upper portion of the stand body 11 in which the display main body 2 can be tilted without interference.

An elastic member 22 may be accommodated in the hollow part 19 formed inside the stand body 11. For example, the elastic member 22 may be a coil spring. The elastic member 22 and the display body 2 are connected to each other by a connecting member 21. That is, one end of the connection member 21 is coupled and fixed to the lower end of the display main body 2, and the other end is connected to the elastic member 22.

The connection member 21 includes a body portion 21a and a coupling portion 21b coupled to the display body 2.

In detail, the coupling part 21b forms an upper end of the connection member 21, and the body part 21a forms a structure extending downward from the center of the coupling part 21b. In addition, the coupling part 21b is provided with a fastening hole 24 through which the fastening member 26 passes. The fastening member 26 penetrates the fastening hole 24 formed in the coupling part 21b and is inserted into the fastening boss 201 formed in the display main body 2 so that the connection member 21 is displayed on the display. It is fastened and fixed to the main body (2). Therefore, the coupling part 21b is in close contact with the display main body 2, so that the connection member 21 is formed in one body with the display main body 2.

The body portion 21a may extend slightly from the coupling portion 21b to the rear of the display body 2. That is, the body portion 21a is not positioned on the same plane as the coupling portion 21b and the display main body 2, and is formed to be inclined backward by a predetermined angle φ. This is to prevent the end of the body portion 21a from rotating in the front-rear direction when the display main body 2 is tilted, so as not to interfere with the inner circumferential surface of the stand body 11 at this time.

The lower end of the connection member 21 is formed with a locking hole 23 for the elastic member 22 is coupled.

One end of the elastic member 22 is coupled to the locking hole 23, the other end is coupled to the locking member 25 provided on the inner circumferential surface of the stand body (11). For example, in the first embodiment, the locking member 25 may be provided to be inserted into the groove 18 formed at the rear of the inside of the stand body 11.

Therefore, when the display main body 2 is tilted backward, the end portion of the body portion 21a forming the connecting member 21 moves forward of the display main body 2. In addition, the connecting member 21 pulls the elastic member 22 to extend the elastic member 22.

When the elastic member 22 is extended, a restoring force is applied to the elastic member 22 to return to its original length. In the first embodiment, since the elastic member 22 is extended forward from the inside rear of the stand body 11, a rotation moment for rotating the display main body 2 forward by the restoring force is generated.

In addition, when the display main body 2 is tilted backward, a rotation moment due to the weight of the display main body 2 is generated. The rotation moment due to the restoring force and the rotation moment due to the own weight of the display main body 2 are offset by acting in opposite directions. In other words, while the display main body 2 is tilted, the elastic modulus of the elastic member 22 is suitably adjusted so that the rotation moment generated by the self-weight of the display main body 2 cancels the rotation moment caused by the restoring force. You can choose.

Therefore, the rotational moment generated by the restoring force of the elastic member 22 cancels the rotational moment caused by the weight of the display main body 2, so as to maintain the tilting state of the display main body 2. The friction force generated at 30 can be reduced.

The shaft coupling portion 15 to which the hinge shaft 31 may be coupled is formed on the stand body 11. The shaft coupling portion 15 has two shaft coupling portions 15 symmetrically formed on the upper left side and the upper right side of the stand body 11. That is, the center of the shaft coupling portion 15 formed on the upper left and right will be on the same line.

The hinge assembly 30 is coupled to the shaft coupling portion 15, and a hinge shaft 31 constituting the hinge assembly 30 is inserted into the shaft coupling portion 15. In order to prevent the hinge shaft 31 from rotating during the tilting of the display main body 2, the inner space of the shaft coupling part 15 may have a shape corresponding to the cross-sectional shape of the hinge shaft 31. Can be. Therefore, the cross-sectional shape of the shaft coupling portion 15 and the hinge shaft 31 may be formed in a polygon.

On the other hand, the hinge assembly 30, one end is inserted into the shaft coupling portion 15, the hinge shaft 31 and the hinge shaft 31, which functions as a rotating shaft when the display body 2 is tilted. A friction member 32 into which the other end of the insert is inserted, and a friction bracket 33 into which the friction member 32 is inserted are included.

In detail, the friction member 32 remains unrotated with the hinge shaft 31, and only the friction bracket 33 is rotated together with the display body 2. Therefore, frictional force is generated at the contact surface between the friction member 32 and the friction bracket 33.

In the present embodiment, the hinge shaft 31 and the shaft coupling portion 15 have been described as being provided as separate parts, but the hinge shaft 31 and the shaft coupling portion 15 may be formed in a single body. Reveal it.

That is, the friction member 32 is forcibly fitted into the fastening groove 332 formed in the friction bracket 33, so that the friction bracket 33 has one degree of freedom capable of rotation only. Therefore, when the display body 2 is tilted, the friction member 32 is rotated in the friction bracket 33 to friction between the inner circumferential surface of the friction bracket 33 and the outer circumferential surface of the friction member 32. This will happen. The tilting state of the display main body 2 is maintained by the friction force.

In addition, the friction bracket 33 is formed with a fastening hole 332 through which the fastening member 34 can pass. The fastening member 34 penetrates the fastening hole 332 formed in the friction bracket 33, and is inserted into the fastening boss 202 formed in the display body 2, thereby allowing the friction bracket 33 to be inserted into the display body. (2) is fastened and fixed.

Accordingly, the stand apparatus 10 and the display main body 2 are connected by the hinge assembly 30 including the hinge shaft 31 and the friction bracket 33.

Hereinafter, a mechanism in which the elastic member 21 acts when the display main body 2 is tilted will be described.

5 is a cross-sectional view taken along the A-A surface of FIG. 1 in a state where the display main body is tilted.

Referring to FIGS. 3 and 5, when the display main body 2 is rotated at an angle θ backward, that is, tilted while the display main body 2 is perpendicular to the base 12, the display main body 2 is rotated. (2) receives a rotation moment which tries to rotate in the tilting direction by its own weight.

That is, when the weight of the display main body 2 is W and the distance from the hinge axis 31 to the center of gravity of the display main body 2 is L1, when the display main body 2 is tilted, The rotation moment due to the weight of the display main body 2 is in accordance with the following equation.

M1 = W * sinθ * L1

When the display body 2 is tilted backward, the connecting member 21 is rotated forward to extend the elastic member 22 coupled to the engaging hole 23.

When the elastic member 22 is elongated, a restoring force is generated to restore to its original length. In other words, when the length of the elastic member 22 is elongated is Δx and the elastic modulus of the elastic member 22 is k, the restoring force of the elastic member 22 is given by the following equation.

F = k * Δx

Since the distance from the hinge shaft 31, which acts as a rotating shaft when the display body 2 is tilted, to the locking hole 23 located at the distal end of the connecting member 21 is L2, the display main body by the restoring force. The rotation moment acting on (2) is as follows.

M2 = k * Δx * L2

The rotation moment M2 by the elastic member 22 acts in the opposite direction to the rotation moment caused by the weight of the display main body 2. Therefore, the rotation moment M1 due to the weight of the display main body 2 is extinguished by the rotation moment M2 due to the restoring force. On the contrary, it may also occur that the rotation moment M2 due to the restoring force is dissipated by the rotation moment due to the weight of the display main body 2.

In order to maintain the tilting state of the display main body 2, only a frictional force of a magnitude that counters the remaining rotation moment canceled is sufficient to the hinge shaft 31. That is, when the rotation moment M1 due to the weight of the display main body 2 is canceled by the rotation moment M2 due to the restoring force of the elastic member 22, the friction force required by the hinge shaft 31 is Compared with the structure without the elastic member 22, it is significantly reduced.

That is, even when a relatively small frictional force acts on the hinge axis 31, the tilting position of the display main body 2 can be maintained.

Therefore, the user adjusts the elastic modulus k value of the elastic member 22, the length of the connecting member 21, and the like, and the rotation moment M2 caused by the restoring force is adjusted to the rotation moment due to the weight of the display main body. Can be set same as M1). In this case, the friction force required for the hinge shaft 31 can be minimized, and the force required for tilting the display main body 2 can be adjusted.

In addition, when the display main body 2 is tilted, the hinge shaft 31 may serve as a support point for supporting and fixing the lever. In addition, the display main body 2 may serve as a force point for applying a force and an end point of the connection member 21 to which the elastic member 22 is coupled to act as a force point.

In the present embodiment, the connecting member 21 extends downward from the lower end of the display main body 2 to a length shorter than the length of the display main body 2. That is, the hinge shaft 31 is located between the display main body 2 and the connecting member 21.

Therefore, the length L1 between the hinge axis 31 and the center of gravity of the display main body 2 is greater than the length L2 from the hinge axis 31 to the end of the connecting member 22. According to the principle of the lever, the display main body 2 can be tilted with a force smaller than the restoring force of the elastic member 22.

According to the proposed embodiment, when the display body 2 is tilted, the rotation moment M1 generated by the self-weight of the display body 2 is generated by the restoring force of the elastic member 22 ( Offset by M2), the frictional force required for the hinge axis 31 is reduced.

Since the frictional force required for the hinge shaft 31 is reduced, the structure of the hinge shaft 31 can be simply implemented, which is suitable for a slim design.

In addition, there is an advantage that the user can optimize the force required to tilt the display body 2 by adjusting the elastic modulus of the elastic member 22, the length of the connection member 21, and the like.

In addition, the hinge coupling structure according to the present embodiment has advantages in terms of cost because the structure is simple and the number of parts is small.

6 is a cross-sectional view taken along the A-A plane of FIG. 1 in a state in which the display main body is tilted according to the second embodiment.

The display device according to the second embodiment differs in the type of elastic member, and the rest of the configuration is the same in function and structure as the display device according to the first embodiment.

In other words, in the first embodiment, the elastic member 22 is a tension spring, and in this embodiment, there is a difference. Therefore, the description of the first embodiment is used except for the description of the type of the elastic member 22.

Referring to FIG. 6, in the display device 100 according to the second embodiment, the elastic member 220 is positioned in front of the connection member 210 so that the elastic member 220 is tilted when the display body 200 is tilted. It is not stretched, it is compressed.

When the display main body 200 is tilted backward, a moment force due to its own weight of the display main body 2 is generated in the tilting direction, and the elastic member 220 is compressed by the connection member 210.

When the elastic member 220 is compressed, a restoring force is generated to restore to the original state. That is, the elastic member 220 generates a rotation moment in a direction opposite to the tilting direction of the display body 2 by the restoring force.

Therefore, the rotation moment due to the weight of the display main body 200 is canceled by the restoring force of the elastic member 220, the same as the first embodiment in that there is an advantage that the friction force required for hinge coupling is reduced. .
