Detailed Description

An embodiment of the present invention will be described below with reference to fig. 1 to 7.

As shown in fig. 1 to 3, the display device 1 of the present embodiment includes a display device main body 2, an expansion slot 3, and a partition member 4. In addition, the display device 1 includes a connector 5.

As shown in fig. 1, the display device main body 2 is formed in a substantially plate shape and has a space therein. The display device main body 2 of the present embodiment includes a plate-shaped display panel 21 having a display surface 21a on a front surface thereof for displaying images and videos, and a back cover 22 covering a back surface side of the display panel 21 facing a side opposite to the display surface 21 a. The space inside the display device main body 2 is mainly formed between the back surface of the display panel 21 and the back cover 22.

As shown in fig. 1 and 2, the display device main body 2 includes a bracket 23 fixed to the back surface side of the display panel 21. The bracket 23 closes a gap between the display panel 21 and the back cover 22, which is open in a first direction (the X-axis positive direction in fig. 1 and 2) along the back surface of the display panel 21. The bracket 23 is formed with an opening 231 that penetrates in the first direction (X-axis direction) so that an extension slot 3 described later faces the outside of the display device main body 2. The opening 231 is formed in a rectangular shape extending long in a second direction (Y-axis direction) orthogonal to the first direction along the rear surface of the display panel 21 when viewed from the first direction.

The bracket 23 is formed by bending a plate material. The bracket 23 is formed with an extension plate portion 232 that is formed by bending a plate material constituting the bracket 23 and integrally extends from an edge portion of the opening 231 toward the internal space of the display device main body in the first direction. The extension plate 232 is provided on a long side portion of the opening 231 extending long in the second direction.

As shown in fig. 1, 2, and 4, the expansion slot 3 is provided in the display device main body 2. Specifically, the expansion slot 3 is provided in a space inside the display device main body 2 (i.e., a gap between the back surface of the display panel 21 and the back cover 22). Various function expansion modules 10 are removably mounted to the expansion slot 3 (see fig. 5 and 6). Specifically, the function expansion module 10 can be inserted into and removed from the expansion slot 3 by passing through the opening 231 of the bracket 23 in the first direction (X-axis direction).

The expansion slot 3 has two

guide rails

32, 33. The two

guide rails

32 and 33 are attached to the back surface side of the display panel 21 and extend in the first direction. The two

guide rails

32, 33 are located at both ends of the expansion slot 3 in the second direction, and define the range of the expansion slot 3 in the second direction. The two

guide rails

32 and 33 guide the function expansion module 10 in the first direction when inserting and removing the function expansion module 10 into and from the expansion slot 3, and hold the function expansion module 10 attached to the expansion slot 3 from the second direction.

The partition member 4 is detachably provided in the expansion slot 3. The dividing member 4 divides the expansion slot 3 into two divided slots 31 aligned in the second direction in a state of being mounted to the expansion slot 3. The function expansion modules 10 (see fig. 6) can be attached to the two divided slots 31. The partition member 4 is disposed between the two

guide rails

32 and 33 in the second direction and is located at a position spaced apart from the two

guide rails

32 and 33 in a state of being attached to the expansion slot 3. The width dimension of each divided slot 31 in the second direction is smaller than the width dimension of the entire expansion slot 3 in the second direction.

In the present embodiment, the partition member 4 attached to the expansion slot 3 is positioned on one side of the two

guide rails

32 and 33. Thus, the width dimensions of the two divided slots 31 in the second direction are different from each other. In the following description, the divided insertion groove 31 having a large width may be referred to as a first divided insertion groove 31A, and the divided insertion groove 31 having a small width may be referred to as a second divided insertion groove 31B.

A part of the partition member 4 attached to the expansion slot 3 is inserted into the opening 231 of the bracket 23, and the opening 231 is divided into two in the second direction. The two divided openings 231 correspond to the two divided slots 31, respectively.

The partition member 4 extends in the first direction in a state of being attached to the expansion slot 3, similarly to the two

guide rails

32 and 33 described above. The dividing member 4 functions as a dividing rail that guides the function expansion module 10 in the first direction together with the

rails

32 and 33 when inserting and removing the function expansion module 10 into and from the divided slot 31, and holds the function expansion module 10 attached to the divided slot 31 from the second direction.

As shown in fig. 2 and 3, the partitioning member 4 of the present embodiment includes an insulating portion 41 having electrical insulation and a conductive portion 42 having electrical conductivity. In fig. 3, the conductor portions 42 are shown in a dot pattern to distinguish them from the insulation portions 41. The insulating portion 41 is made of, for example, plastic, and constitutes a rail portion of the dividing member 4 that guides the function expansion module 10 mainly in the first direction. The conductor portion 42 is made of, for example, metal, and is formed separately from the insulating portion 41 and attached to the insulating portion 41. The conductor portion 42 is formed by bending a metal plate material.

The conductor portion 42 is connected to a portion (conductive portion) having conductivity in the display device main body 2 in a state where the partition member 4 is attached to the expansion slot 3. In the present embodiment, the conductive portion of the display device main body 2 is a conductive chassis 24 provided on the rear surface side of the display panel 21.

The conductor portion 42 includes a flat plate portion 421 disposed to overlap the bottom plate 24 in a state where the partition member 4 is attached to the expansion slot 3. The flat plate portion 421 is formed with a spring portion 422 that protrudes from the flat plate portion 421 toward the bottom plate 24 side and is elastically deformable relative to the flat plate portion 421. Therefore, in a state where the partition member 4 is attached to the expansion slot 3, the spring portion 422 is pressed against the bottom plate 24 by its own elastic force. This ensures electrical connection between the conductor part 42 and the bottom plate 24.

The partition member 4 may be attached to the extension slot 3 by being fixed to the chassis 24 and the display panel 21 by, for example, screwing. In the present embodiment, the partition member 4 is fixed to the bracket 23 via the cover 12 (for example, the cover 12 of the function expansion module 10 (see fig. 6)) covering the opening 231 of the bracket 23, and the partition member 4 is attached to the expansion slot 3. This point will be specifically explained below.

The conductor portion 42 of the partition member 4 includes an insertion plate portion 423 that is inserted into the opening 231 of the bracket 23 in a state where the partition member 4 is attached to the extension slot 3. The insertion plate portion 423 is formed with two screw holes 424 aligned in the second direction in a state where the insertion plate portion 423 is inserted into the opening portion 231 of the bracket 23. The two screw holes 424 of the insertion plate portion 423 are used for screw fastening of the cover 12 covering the opening 231 of the bracket 23 together with the screw hole 234 formed in the bracket 23. In a state where the cover 12 is screwed to the bracket 23 and the insertion plate portion 423, the partitioning member 4 is fixed to the bracket 23 via the cover 12.

When the partition member 4 is fixed to the bracket 23 via the cover 12, the partition member 4 can be attached to and detached from the expansion slot 3 only by detaching the cover 12 from the partition member 4 and the bracket 23. That is, the partitioning member 4 can be attached and detached without removing the back cover 22 from the back surface side of the display panel 21.

As shown in fig. 2 and 4, the connector 5 is disposed in the expansion slot 3. Two connectors 5 are arranged in the second direction so as to correspond to the two divided slots 31 (the first divided slot 31A and the second divided slot 31B), respectively. That is, the first connector 51 of the two connectors 5 is disposed in the first divided insertion groove 31A, and the second connector 52 is disposed in the second divided insertion groove 31B. Both connectors 5 are located at the end of the function expansion module 10 in the expansion slot 3 on the front side in the insertion direction (X-axis negative direction side). These first and

second connectors

51 and 52 are located at positions offset from each other in the first direction. Specifically, the first connector 51 is located at a position shifted to the front side (X-axis negative direction side) in the insertion direction of the function expansion module 10 in the first direction from the second connector 52.

The two connectors 5 are mounted on a circuit board 7 constituting a circuit of the display device 1. Thus, the function expansion module 10 mounted in the expansion slot 3 is connected to the connector 5, whereby the function expansion module 10 can be connected to the circuit of the display device 1.

Next, the function expansion module 10 mounted to the expansion slot 3 of the display device 1 will be described with reference to fig. 5 and 6.

The function expansion module 10 is attached to the expansion slot 3 and connected to the connector 5, thereby being connected to the circuit of the display device 1 to expand the function of the display device 1. The function extension Module 10 may be, for example, an OPS (Open plug Specification), SDM-L, SDM-S, which is a Smart Display Module (Smart Display Module) of Intel corporation, and RPi-CMIF, which is a Raspberry Pi (Raspberry Pi).

The function expansion module 10 includes a module body 11 inserted into the expansion slot 3, and a cover 12 fixed to an end of the module body 11. The module main body 11 includes a substrate and the like constituting a circuit of the function expanding module 10. The cover 12 is arranged to overlap the bracket 23 with the module main body 11 inserted into the extension slot 3, and covers the opening 231 of the bracket 23 from the outside of the display device main body 2. The function expansion module 10 can be fixed to the display device 1 by screwing the cover 12 to the bracket 23 and the partition member 4 in a state where the function expansion module 10 is mounted to the expansion slot 3.

In the display device 1 of the present embodiment, three types of function expansion modules 10 can be mounted in the same expansion slot 3. Hereinafter, the various kinds of function expanding modules 10 will be described.

As shown in fig. 5, the function expansion module 10 includes a large function expansion module 10A that is removably attached to the expansion slot 3 in a state where the partition member 4 is removed from the expansion slot 3.

The width dimension of the large function expansion module 10A corresponds to the width dimension of the expansion slot 3 (the distance between the two guide rails 32, 33). Thus, when the large-sized function expansion module 10A is attached to the expansion slot 3, the large-sized function expansion module 10A is guided in the first direction by the two

guide rails

32 and 33. The large-sized function expansion module 10A attached to the expansion slot 3 is held by the two

guide rails

32 and 33 from the second direction. In the illustrated example, the large function expansion module 10A is connected to the second connector 52 in a state of being mounted in the expansion slot 3, but may be connected to the first connector 51, for example.

As shown in fig. 6, the function expansion module 10 includes two small

function expansion modules

10B and 10C that are removably mounted in the two divided slots 31 in a state where the partition member 4 is mounted in the expansion slot 3. The width of each of the two small-sized

function expansion modules

10B and 10C is smaller than the width of the large-sized function expansion module 10A.

The width of the first expansion module 10B of the two

small expansion modules

10B and 10C corresponds to the width of the first split slot 31A (the distance between one of the guide rails 32 and the partition member 4). When the first function expansion module 10B is attached to the first divided slot 31A, the first function expansion module 10B is guided in the first direction by one of the guide rails 32 and the partitioning member 4. The first function expansion module 10B attached to the expansion slot 3 is held from the second direction by one of the guide rails 32 and the partitioning member 4. The first function expansion module 10B is connected to the first connector 51 in a state of being attached to the first division slot 31A.

The width of the second expansion module 10C of the two

small expansion modules

10B and 10C corresponds to the width of the second divided insertion groove 31B (the distance between the other guide rail 33 and the partition member 4), and is smaller than the width of the first expansion module 10B. In addition, the length dimension of the second function expansion module 10C in the first direction is smaller than the length dimension of the first function expansion module 10B.

When the second function expansion module 10C is attached to the second divided slot 31B, the second function expansion module 10C is guided in the first direction by the other guide rail 33 and the partitioning member 4. The second function expansion module 10C attached to the expansion slot 3 is held from the second direction by the other guide rail 33 and the partition member 4. The second function expansion module 10C is connected to the second connector 52 in a state of being mounted in the second divided slot 31B.

As illustrated in fig. 6, both the first and second

function expansion modules

10B and 10C may be mounted on the expansion slot 3 to which the partition member 4 is mounted, but for example, only one of the first and second

function expansion modules

10B and 10C may be mounted.

In this case, the width of the first function expansion module 10B is larger than the width of the second divided insertion groove 31B. Therefore, the first function expansion module 10B is not erroneously inserted into the second divided insertion groove 31B, and as a result, is not erroneously connected to the second connector 52. On the other hand, the width of the second function expanding module 10C is smaller than the width of the first dividing insertion groove 31A. Thus, for example, as shown in fig. 7, the second function expansion module 10C may be erroneously inserted into the first divided insertion slot 31A.

In the display device 1 of the present embodiment configured as described above, the division member 4 is attached to the extension slot 3, whereby the method of dividing the extension slot 3 into two divided slots 31 can be implemented. Each width dimension of the two divided slots 31 obtained by this dividing method is smaller than the width dimension of the expansion slot 3.

As described above, the display device 1 of the present embodiment includes the dividing member 4 that is detachably provided in the expansion slot 3 and divides the expansion slot 3 into the two divided slots 31. Therefore, by attaching and detaching the partition member 4 to and from the extension slot 3, a plurality of types of function extension modules 10 having different width dimensions in the second direction can be attached to the same extension slot 3 of the display device main body 2. For example, in a state where the partition member 4 is detached from the expansion slot 3, the function expansion module 10(10A) having a large width can be attached to the expansion slot 3. On the other hand, in a state where the partition member 4 is attached to the extension slot 3, since two divided slots 31 having a smaller width dimension than the extension slot 3 are formed, the function extension modules 10(10B, 10C) having a smaller width dimension can be attached to the respective divided slots 31. This can reduce the number of expansion slots 3 provided in the display device main body 2. Therefore, the cost of the display device 1 can be reduced.

In addition, as compared with the case where the extension slot 3 of the display device main body 2 is prepared for each specification (particularly, width dimension) of the function extension module 10, the occupied area of the extension slot 3 in the display device main body 2 can be suppressed to be small.

In the display device 1 of the present embodiment, the dividing member 4 is attached to the expansion slot 3 so that the width dimensions of the two divided slots 31 are different from each other. Therefore, two kinds of function expansion modules 10 (first and second

function expansion modules

10B and 10C) having different width dimensions can be attached to the two divided slots 31. Therefore, the number of the expansion slots 3 provided in the display device main body 2 can be further reduced to further reduce the cost of the display device 1, and the occupied area of the expansion slots 3 in the display device main body 2 can be further reduced.

In the display device 1 of the present embodiment, the two connectors 5 arranged in the second direction are located at positions offset from each other in the insertion and extraction direction (first direction) of the function expansion module 10 into and from the expansion slot 3. Specifically, the first connector 51 provided in the first divided insertion slot 31A is located at a position shifted to the front side in the insertion direction of the function expansion module 10 in the first direction from the second connector 52 provided in the second divided insertion slot 31B. In addition, the length dimension of the second function expansion module 10C in the first direction is shorter than the length dimension of the first function expansion module 10B. Therefore, as shown in fig. 7, even if the second function expansion module 10C is erroneously inserted into the first divided insertion groove 31A, the second function expansion module 10C is located at a position spaced apart from the first connector 51 in the first direction. Therefore, the second function expanding module 10C can be prevented from being erroneously connected to the first connector 51.

In the display device 1 of the present embodiment, the partitioning member 4 includes the insulating portion 41 and the conductor portion 42. The insulating portion 41 of the partitioning member 4 may be electrostatically charged, and thus may cause noise such as electromagnetic interference (EMI). In the partition member 4 of the present embodiment, the conductor portion 42 is attached to the insulating portion 41. The conductor portion 42 is electrically connected to the conductive portion (the bottom plate 24) of the display device main body 2 in a state where the partition member 4 is attached to the expansion slot 3. Therefore, the insulating portion 41 can be grounded. This can suppress the electrostatic charging of the insulating portion 41 and suppress or prevent the generation of noise due to the insulating portion 41.

In addition, according to the display device 1 and the division method of the expansion slot 3 of the present embodiment, the width dimensions of the slots (expansion slot 3, division slot 31) can be easily switched simply by attaching and detaching the dividing member 4 to and from the expansion slot 3.

In the display device 1 of the present embodiment, the plate member constituting the bracket 23 is bent to form the extension plate portion 232 integrally extending from the edge of the opening 231 in the insertion direction (first direction) of the function expansion module 10. Therefore, the edge of the opening 231 is formed in a circular arc shape. Thus, when the function expansion module 10 is inserted into the expansion slot 3 through the opening 231 of the bracket 23, the function expansion module 10 (particularly, the module main body 11) can be prevented or prevented from being scratched by the edge of the opening 231. In other words, the function expansion module 10 can be protected.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within a range not departing from the gist thereof.

In the display device of the present invention, the width dimensions of the two divided slots 31 may be equal to each other, for example.

The display device of the present invention may include a plurality of partitioning members 4. In this case, the plurality of dividing members 4 are provided in the extension slot 3 so as to be arranged at intervals in the second direction, and thus the extension slot 3 can be divided into three or more divided slots 31.

As shown in fig. 8, for example, the display device of the present invention may be provided with at least a display device main body 2, an expansion slot 3 provided in the display device main body 2 and to which a function expansion module 10 is attached so as to be able to be inserted and removed in a first direction (X-axis direction), and a dividing member 4 provided in the expansion slot 3 so as to be detachable and dividing the expansion slot 3 into two divided slots 31 arranged in a second direction (Y-axis direction) orthogonal to the first direction.
