Detailed Description

For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail below by referring to the accompanying drawings and examples.

Fig. 1 is a schematic diagram of an assembly structure of an interface device in an embodiment of the present application. Fig. 2 is an exploded view of the interface device of the embodiment shown in fig. 1. Referring to fig. 1 and 2, in an embodiment of the present application, an interface apparatus for a display device may include a mounting member 10 and a rotary drum 30.

Wherein the rotary drum 30 is rotatably mounted to the mounting member 10. For example, the mounting member 10 may include a hollow frame, that is, the mounting member 10 may include a pair of stay plates 13, and first and second connection plates 11 and 12 connected (e.g., welded) between the pair of stay plates 13, for example, both the stay plates 13 and the first and second connection plates 11 and 12 may be sheet metal pieces, and the hollow frame of the mounting member 10 may be welded from these sheet metal pieces, and the rotary drum 30 may be located in a frame space formed by surrounding the pair of stay plates 13 and the first and second connection plates 11 and 12, and the drum end plate 313 of the rotary drum 30 may be rotatably connected with the pair of stay plates 13.

Also, the physical interface 300 built in the rotary drum 30 is exposed at the wall of the rotary drum 30. In embodiments of the present application, the physical interface 300 built into the rotating drum 30 and exposed at the wall of the rotating drum 30 may include one, or more than one (three are illustrated in fig. 1 and 3). For example, the physical interface 300 may include at least one of a USB interface and an HDMI interface, wherein the USB interface may include at least one of a Type (Type-a), a Type B (Type-B), and a Type C (Type-C).

Thus, when the mounting member 10 is mounted to the display device, by rotating the rotary drum 30 relative to the mounting member 10 in response to an external force operation, the orientation of the physical interface 300 relative to the display device can be adjusted to enable the physical interface 300 to be switched between an orientation in which the insertion and extraction operation is convenient to be performed, and an orientation for avoiding a collision by mistake.

Fig. 3 is a schematic diagram of an exemplary structure of a display apparatus to which the interface device in the embodiment shown in fig. 1 is applied. Fig. 4 is a schematic diagram of an assembly structure of the interface device in the display apparatus according to the embodiment shown in fig. 1. Referring to fig. 1 and 2 together with fig. 3 and 4, in an embodiment of the present application, the display apparatus 80 using the interface device as shown in fig. 1 may include a display panel 800, for example, the display panel 800 may be an LCD (Liquid Crystal Display ) or OLED (Organic Light Emitting Diodes, organic light emitting diode) display screen, and the display panel 800 may be a large-sized screen such as 86 inch screen; the display device 80 may further include a device bezel 90 located at an edge of the display panel 800 and having an open slot 900.

In fig. 3, a vertical placement posture of the display device 80 by a wall-hanging installation is shown, and in fig. 3 and 4, the device bezel 90 is exemplified as a lower bezel located at a lower edge of the display panel 800. In addition, in fig. 3 and 4, the display device 80 is also exemplified as a smart tablet, that is, the display device further includes a tablet 93 (e.g., a blackboard or whiteboard) located outside at least one side of the display panel 800, so that the display device 80 can perform content explanation with the aid of the manual writing content on the tablet 93 while performing content presentation with the display panel 800. It will be appreciated that the pictorial representations in fig. 3 and 4 should not be construed as limiting the display device 80, i.e., the display device 80 may also be a purely smart screen that does not include a tablet 93, in which case the device bezel 90 with the open slot 900 may still be a lower bezel, or may also be a side bezel located at any side edge of the display panel 800.

Referring to fig. 4 in particular, in the embodiment of the present application, whether the device bezel 90 having the open slot 900 is a lower bezel or a side bezel, the device bezel 90 located at the edge of the display panel 800 has a bezel front facing surface 91 that is co-directional with the display panel 800, and a bezel outer wall surface 92 that intersects the bezel front facing surface 91 adjacently (e.g., perpendicular to the bezel front facing surface 91). If the apparatus frame 90 having the open slot 900 is a lower frame, the outer wall 92 of the frame is a lower wall of the lower frame facing away from the display panel 800; if the device frame 90 having the open slot 900 is a side frame, the frame outer wall surface 92 is a side wall surface of the side frame facing away from the display panel 800. Also, the open slot 900 of the device bezel 90 may have a first open area 910 located at the bezel front face 91, and a second open area 920 located at the bezel outer wall 92.

The open slot 900 of the device frame 90 is used to mount an interface device applied to the display device 80, i.e., the mounting member 10 of the interface device may be mounted to the open slot 900 of the device frame 90 of the display device 80.

For example, in the case where the mounting member 10 includes a hollow frame body, the hollow frame body of the mounting member 10 may be integrally placed in the open groove 900, that is, both the pair of stay plates 13 and the first and second connection plates 11 and 12 connected between the pair of stay plates 13 are in the open groove 900, and accordingly, the rotary drum 30 rotatably connected with the pair of stay plates 13 by the drum end plate 313 is also placed in the open groove 900. When the mounting member 10 including the hollow frame is mounted in the open groove 900, the space opening of the frame space of the hollow frame may be directed toward the first opening area 910, and the second connection plate 12 is close to the frame outer wall surface 92 and is away from the second opening area 920. Further, in order to facilitate the fixation of the mounting member 10 in the open slot 900, the mounting member 10 may further include an ear plate 15, the ear plate 15 being connected at the junction of the stay plate 13 and the second connection plate 12 and being bent with respect to the stay plate (13), and, when the mounting member 10 is mounted in the open slot 900, the ear plate 15 may protrude outside the second opening area 920 of the open slot 900 and be fixed to the bezel outer wall surface 92 with the first screw, so that, based on the fixed connection between the ear plate 15 and the bezel outer wall surface 92, the position of the mounting member 10 (i.e., the interface device) may be fixed in the direction X in which the device bezel 90 extends (e.g., the width direction of the display device 80), in the direction Y parallel to the display panel 800 and perpendicular to the device bezel 90 (e.g., the height direction of the display device 80), and in the direction Z perpendicular to the display panel 800 (e.g., the thickness direction of the display device 80).

Moreover, the interface device can be detachably assembled on the display device 80 (i.e., the device frame 90) by using the ear plate 15 of the mounting member 10 and the first screw, so that the interface device is convenient to be detached on the display device 80 (i.e., the device frame 90), and therefore, the hardware replacement and maintenance of the display device 80 are convenient.

Fig. 5 is a schematic diagram showing an embedded state of the interface device in the display apparatus according to the embodiment shown in fig. 1. Fig. 5 shows a rear side structure of the display device 80, and as shown in fig. 5, when the mounting member 10 is mounted to the display device, the mounting member 10 may be flush with a rear frame surface 94 of the device frame 90, the rear frame surface 94 being a side of the wall where the device frame 90 is wall-mounted toward the display device 80, and as can be seen from fig. 5, a wall-mounted bracket 95 for wall-mounting the display device 80 is mounted on a rear surface of the display panel 800 of the display device 80.

In addition, the frame rear surface 94 of the apparatus frame 90 may be further provided with a limiting structure such as a hook, etc., which can be in limiting engagement with the first connection plate 11 of the mounting member 10, so that the mounting member 10 (i.e., the interface device) is fixedly limited on one side of the first connection plate 11 by means of the limiting constraint of the limiting structure and on the other side of the second connection plate 12 by means of the ear plate 15 by means of the double-sided stabilizing structure.

Referring back to fig. 4, when the mounting member 10 is mounted to the open slot 900 of the device frame 90 of the display device 80, the phase posture of the rotating drum 30 mounted to the mounting member 10 in the open slot 900 is rotated, and can be switched between the first rotational phase phaopt and the second rotational phase phaprt in response to an external force operation. Wherein the physical interface 300 is located in a first opening area 910 of the open slot 900 (i.e., an orientation for performing a plugging operation) when the rotary drum 30 is in the first rotational phase, phaopt, and the physical interface 300 is located in a second opening area 920 of the open slot 900 (i.e., an orientation for avoiding a miss collision) when the rotary drum 30 is in the second rotational phase, phaopt. For example, in case the apparatus frame 90 is a lower frame, the physical interface 300 may be perpendicular to the first opening area 910 and have an angle difference of 0 ° with respect to the horizontal direction when the rotary drum 30 is at the first rotation phase phaopt, and the physical interface 300 may be vertically downward perpendicular to the second opening area 910 and have an angle view of-90 ° with respect to the horizontal direction when the rotary drum 30 is at the second rotation phase phaprt.

That is, in the embodiment of the present application, the interface device for the display apparatus includes the mounting member 10, and the rotating drum 30 rotatably mounted to the mounting member 10, wherein the physical interface 300 built in the rotating drum 30 may be exposed at the wall of the rotating drum 300, and thus, when the interface device is mounted to the open slot 900 of the apparatus bezel 90 of the display apparatus 80, the rotating drum 30 may be rotated in response to an external force operation, so that the exposed orientation of the physical interface 300 may be switched between the bezel front face 91 of the apparatus bezel (i.e., the orientation in which the first opening area 910 is located to facilitate the execution of the insertion operation) and the bezel outer wall face 92 (i.e., the orientation in which the second opening area 920 is located to avoid the erroneous collision), thereby, it may be ensured that the physical interface 300 is convenient to perform the insertion operation when being exposed to the bezel front face 91, and also may be possible to avoid the erroneous collision occurring due to the front of the bezel front face 91 of the data source or the docking cable connector by hiding the physical interface 300 in the connection state with the data source to the bezel outer wall face 92, thereby helping to reduce the risk of failure of the connection of the data source and the physical interface 300.

In the embodiment of the present application, the rotation of the rotary drum 30 with respect to the mounting member 10 may be a damped rotation, for example, the drum end plate 313 of the rotary drum 30 and the at least one stay plate 13 may be rotatably connected by the rotary damper 21 (the rotary damper 21 may be fixed to the stay plate 13 with the second screw 62) so that the rotary drum 30 may be stationary without an external force operation.

Referring back to fig. 1 and 2, at least one of the stay plates 13 of the mounting member 10 may be provided (preferably, a pair of stay plates 13 are each provided) with the rotary damper 21 fixed by the second screw 62, at least one corresponding drum end plate 313 of the rotary drum 30 has (preferably, a pair of drum end plates 313 each have) an end plate shaft hole 3130, and a damping rotation shaft of the rotary damper 21 provided to any stay plate 13 may be coaxially connected with the end plate shaft hole 3130 of the corresponding drum end plate 313. For example, any one of the stay plates 13 may be provided with a rotary damper 21 on an outer side surface outside the frame space, and a damping rotation shaft of the rotary damper 21 may pass through a stay plate through hole 130 formed in the stay plate 13 and be coaxially connected to an end plate shaft hole 3130 of the corresponding drum end plate 313. Also for example, the damping shaft of the rotary damper 21 may be a flat key shaft having a waist-shaped cross section, the end plate shaft hole 3130 of the drum end plate 313 may be a waist-shaped hole, and the damping shaft of the rotary damper 21 (i.e., the flat key shaft) may be interference-fitted with the end plate shaft hole 3130 of the drum end plate 313 (i.e., the waist-shaped hole).

In the embodiment of the present application, a positioning mechanism may be provided for rotation of the rotary drum 30 with respect to the mounting member 10 so that the rotary drum 30 can be accurately rotated in response to an external force operation to either one of the first rotational phase phaopt and the second rotational phase phaprt.

Referring back to fig. 1 and 2, at least one stay 13 of the mounting member 10 may have (preferably, a pair of stay 13 each has) a first positioning hole 131 and a second positioning hole 132, wherein a phase difference between the first positioning hole 131 and the second positioning hole 132 about the coaxial end plate shaft hole 3130 and the stay through hole 130 is equal to a phase difference between the first rotational phase phaopt and the second rotational phase phaprt of the rotating drum 30, for example, both are 90 °; also, at least one corresponding drum end plate 313 of the rotary drum 30 may be mounted (preferably, a pair of drum end plates 313 are each mounted) with spring balls 40, for example, the drum end plate 313 may have spring ball mounting holes 3134, and the spring balls 40 may be mounted to the spring ball mounting holes 3134. Based on the above structure:

when the rotary drum 30 is at any phase between the first rotation phase phaopt and the second rotation phase phaprt, the spring balls 40 are compressed by the supporting plate 13, and at this time, the compressed spring balls 40 compressed by the supporting plate 13 form friction with the supporting plate 13, which can generate a damping effect during the rotation of the rotary drum 30 between the first rotation phase phaopt and the second rotation phase phaprt;

when the rotary drum 30 is at the first rotational phase phaopt, the spring balls 40 are aligned with the first positioning holes 131, and since the pressing of the shutter 13 disappears at the first positioning holes 131, the spring balls 40 can be elastically inserted into the first positioning holes 131, and the positioning engagement formed by the elastic insertion of the spring balls 40 into the first positioning holes 131 generates a resistance force greater than the damping force to the rotation of the rotary drum 30, so that the generation of the resistance force can generate a feel indication for an external force-operated force applying person (e.g., an interpreter) that is adjusted in place, and the resistance force greater than the damping force tends to keep the rotary drum 30 at the first rotational phase phaopt and helps to keep the physical interface 300 at the first opening area 910 of the opening groove 900 of the apparatus frame 90;

when the rotating drum 30 is in the second rotational phase, the spring balls 40 may similarly spring out into the second positioning holes 132 and may likewise generate a tactile cue of the force being applied by the external force operator (e.g., the interpreter) to adjust into place and help to maintain the rotating drum 30 in the second rotational phase Pha_prt and help to maintain the physical interface 300 at the second opening area 920 of the opening slot 900 of the device frame 90.

It will be appreciated that the positioning mechanism described above may be used either simultaneously with the rotary damper 21 described above or alone in the case of the rotary damper 21 being provided, since the spring balls 40 in the positioning mechanism described above may also provide a damping effect on the rotation of the rotary drum 30 relative to the mounting member.

In the embodiment of the present application, whether or not the aforementioned rotary damper 21 and/or spring ball 40 are used, a limit mechanism for preventing the excessive adjustment may be provided for the rotation of the rotary drum 30 with respect to the mounting member.

Referring back to fig. 1 and 2, at least one roller end plate 313 of the rotating roller 30 may have a first limit edge 3131 and a second limit edge 3132 (preferably both roller end plates 313 have); at least one corresponding stay plate 13 of the mounting member 10 may be provided with a stop screw 22 (preferably, a pair of stay plates 13 are provided), wherein the stop screw 22 may be provided through the stay plate 13, and the stop screw 22 provided through any one stay plate 13 may be suspended in a circular gap between the first stop edge 3131 and the second stop edge 3132 adjacent to the corresponding roller end plate 313 of that stay plate 13, wherein:

when the external force operation causes the rotating drum 30 to generate an excessive rotation trend relative to the first rotation phase Pha_opt, the first limiting edge 3131 is limited and blocked by the limiting screw 22;

when the external force operates to cause the rotating drum 30 to generate an excessive rotation tendency with respect to the second rotation phase phaprt, the second stopper 3132 is stopped by the stopper screw 22.

In the embodiments of the present application, to facilitate the built-in assembly of the physical interface 300 to the rotating drum 30, a preferred structure is also provided for the rotating drum 30.

In addition, the interface carrier plate 311 may further be provided with a press-riveting stud 312, and the circuit board 331 may be fixed to the press-riveting stud 312 by using the third screw 63, so as to realize the fixed installation of the physical interface 300 on the roller frame 31.

The semi-closed cylindrical housing 32 may be formed by bending a sheet metal member in a plate shape, wherein the bent sheet metal member is not completely closed so that the semi-closed cylindrical housing 32 has a cylindrical fracture 321, and the bent sheet metal member may form a cylindrical space with both ends open so that both ends of the semi-closed cylindrical housing 32 have end openings 322. In addition, the sheet metal part bent to form the semi-closed cylindrical housing 32 may also be perforated so that the semi-closed cylindrical housing 32 may also have an interface exposure hole 320.

The drum frame 31 may be fixedly connected to the semi-closed cylindrical shell 32 at a cylindrical fracture 321 of the semi-closed cylindrical shell 32, for example, the semi-closed cylindrical shell 32 may have a fracture flange 323 at an edge of the cylindrical fracture 321, the drum frame 31 may further include a butt-joint mounting bar 314 connected between a pair of drum end plates 313, and the butt-joint mounting bar 314 may be fixedly connected to the fracture flange 323 by a fourth screw 64.

Based on the fixed connection of the roller skeleton 31 with the semi-closed cylindrical shell 32 at the cylindrical fracture 321 of the semi-closed cylindrical shell 32, it is possible to make: the interface module 33 is accommodated inside the semi-closed cylindrical housing 32 (i.e., within the cylindrical space of the semi-closed cylindrical housing 32), the physical interface 300 is exposed through the interface exposing hole 320 opened in the semi-closed cylindrical housing 32, and the drum end plate 313 is located at the end opening 322 of the semi-closed cylindrical housing 32.

In the embodiment of the present application, the interface module 33 may further have a flexible wire harness 333 for electrically connecting with the display panel 800, for example, the interface module 33 further includes a circuit board 331 integrated with the physical interface 300 and the wire harness connector 332, and the flexible wire harness 333 connected to the wire harness connector 332. The flexible harness 333 may include a power supply harness 3331 and a data signal harness 3332, and accordingly, the harness connector 332 may include a power supply harness connector 3321 for connecting the power supply harness 3331 and a signal harness connector 3322 for connecting the data signal harness 3332, so that the physical interface 300 of the interface module 33 may receive power supply of the built-in power module of the display panel 800 through the power supply harness 3331, and the physical interface 300 of the interface module 33 may provide data signals from a data source and for content presentation to the built-in processor of the display panel 800 through the data signal harness 3332, for example, the data signal harness 3332 may include an FFC (flexible flat cable ).

As the rotary drum 30 rotates relative to the mounting member 10, the flexible wire harness 333 can adapt to different orientations of the physical interface 300 through deformation, but at the same time, if deformation of the flexible wire harness 333 is not limited, the connection between the flexible wire harness 333 and the harness connector 332 is easily broken after the rotary drum 30 rotates for a plurality of times. Thus, in the embodiment of the present application, the rotary drum 30 may further include a wire pressing sheet 34, the wire pressing sheet 34 may be made of plastic material, the wire pressing sheet 34 may be fixed to the butt-joint mounting bar 314 by the fourth screw 64, and the flexible wire harness 333 may pass between the wire pressing sheet 34 and the butt-joint mounting bar 314, and a portion of the flexible wire harness 333 located between the wire pressing sheet 34 and the butt-joint mounting bar 314 is clamped and fixed. With such a structure, the flexible wire harness 333 is not deformed with the rotation of the rotary drum 30 from the end connected to the harness connector 322 to the harness section at the portion between the wire pressing piece 34 and the butt-mounting bar 314, and thus, it is possible to avoid that the connection of the flexible wire harness 333 and the harness connector 332 is easily broken after the rotary drum 30 is rotated a plurality of times.

The foregoing description of the preferred embodiments of the present utility model is not intended to limit the utility model to the precise form disclosed, and any modifications, equivalents, improvements and alternatives falling within the spirit and principles of the present utility model are intended to be included within the scope of the present utility model.
