Detailed Description

In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the utility model, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the related art, the tiled infrared touch display device 100 'includes a plurality of display units 110', each display unit 110 'has a supporting unit, and each display unit 110' is connected to a position to be mounted through a respective supporting unit. Considering that the display unit 110' has an assembly gap with the position to be mounted, the display unit 110' has a certain movement space relative to the position to be mounted, which may cause the display unit 110' to be tilted, and taking fig. 1 as an example, after two adjacent display units 110' are tilted, the touch glasses of the two display units 110' are tilted at one side facing each other. In this way, part of infrared rays in the infrared light beams emitted from the infrared emitting element of one of the display units 110' can be emitted toward the infrared receiving element of the other display unit 110', resulting in a disordered touch signal of the tiled infrared touch display device 100 '.

In view of this, an embodiment of the present application provides a tiled infrared touch display device, which includes a fastening component, configured to connect two adjacent display units, and make the plane surfaces of the two adjacent display units coplanar, so as to improve the assembly precision of the tiled infrared touch display device, and avoid that a part of infrared rays in an infrared beam emitted by an infrared emitter of one display unit is emitted toward an infrared receiver of the other display unit, and thus avoid a situation of touch signal confusion.

Referring to fig. 2 to 6, the present embodiment provides a tiled infrared touch display device 100, which includes a plurality of display units 110, and the display units 110 are arranged in parallel. In this way, the plurality of display units 110 may display different image information, respectively, or the plurality of display units 110 may display a part of the entire image information, respectively.

The models of the plurality of display units 110 may be the same or different. The plurality of display units 110 may be arranged in rows in a horizontal direction, in columns in a vertical direction, or in rows and columns. In the present embodiment, the tiled infrared touch display device 100 includes two display units 110 with the same model, and the two display units 110 are arranged along the horizontal direction, and the touch glasses of the two display units 110 are located on the same plane.

Each display unit 110 is connected to a position to be mounted (not shown), that is, each display unit 110 is independently fixed to the position to be mounted. The position to be installed can be a wall or a movable fixed seat and the like.

The display unit 110 includes a bezel, a touch glass, and a rear case 111. The frame is of an annular frame structure and is arranged around the outer side of the touch glass, and the touch glass is arranged on the front side of the rear shell 111. Taking a rectangular frame as an example, the frame includes four edge strips, and the four edge strips are respectively disposed on the top side, the ground side, the left side and the right side of the touch glass. Wherein the left and right sides of the display unit 110 refer to the left and right sides of the user when the user performs a touch operation toward the display unit 110. Accordingly, the side of the display unit 110 facing the user is the front side, and the side of the display unit 110 facing away from the user is the rear side.

The rear case 111 is connected to a rear side of the bezel, and a display device (not shown) of the display unit 110 is located between the touch glass and the rear case 111 to protect the display device.

The display unit 110 further includes a circuit board (not shown) located inside the bezel, and provided with an infrared emitting element and an infrared receiving element respectively disposed at opposite sides of the bezel. Illustratively, the side strips of the frame on the left side and the sky side are provided with infrared transmitters, and the side strips of the frame on the right side and the ground side are provided with infrared receivers. Thus, the central lines of the infrared light beams emitted by the infrared emitting elements can form a crisscross infrared matrix.

When the user does not perform touch operation, the infrared light beam emitted by the infrared emitting piece is not blocked, the infrared receiving piece can receive the infrared light beam emitted by the infrared emitting piece, and the circuit board judges that the user does not perform touch according to the infrared light beam received by the infrared receiving piece.

When a user touches the touch control glass, for example, the infrared ray beam emitted by the infrared emitting piece is blocked, and the infrared receiving piece cannot receive the infrared ray beam emitted by the infrared emitting piece. At this time, the circuit board judges that the user performs the touch operation because the infrared receiving part does not receive the infrared light beam emitted by the infrared emitting part.

In some possible embodiments, the tiled infrared touch display device 100 further includes a fastening assembly, and for convenience of illustration, two adjacent display units 110 may be referred to as a first display unit and a second display unit. The fastening assembly includes, among other things, a fitting 120 and a fastener (not shown), which may be a locking pin, a threaded fastener, etc. Two ends of the mounting member 120 are simultaneously mounted on the rear cases 111 of two adjacent display units 110, the number of the fasteners is multiple, and the mounting member 120 is respectively connected with the rear cases 111 of two adjacent display units 110 through the fasteners, so that the planes of the multiple display units 110 are coplanar.

The plane of the display unit 110 is parallel to the touch glass. For example, the plane may be understood as a front wall surface of the touch glass.

That is, the attachment member 120 is an integral structure, for example, the attachment member 120 may be approximately a plate-shaped structure, contact surfaces are disposed at two ends of the attachment member 120, the contact surfaces are used for abutting against the fixing portion 1111, that is, the attachment surface is attached to the wall surfaces of the two rear cases 111, and the relative angle between the two adjacent display units 110 is limited, so that the planes where the two adjacent display units 110 are located are coplanar, and therefore, the situation that the touch signals are disordered due to the relative inclination between the two adjacent display units 110 is avoided.

Specifically, the plate-shaped mount 120 is disposed behind the display unit 110, and has less influence on the appearance of the split infrared touch display device 100.

The fasteners are multiple, one end of the mounting piece 120 is connected with the first display unit through at least one fastener, the other end of the mounting piece is connected with the second display unit through at least one fastener, and the connection stability is high.

In some embodiments, the rear case 111 has a fixing portion 1111, the rear case 111 generally has a plurality of portions, the fixing portion 1111 and the protective portion, the fixing portion 1111 is disposed around a circumferential edge of the protective portion, the fixing portion 1111 is parallel to the touch glass, and a fastening member between the rear case 111 and the bezel is also located on the fixing portion 1111 to prevent the fastening member between the rear case 111 and the bezel from being skewed. The protection part corresponds to components such as a controller of the display unit 110, and the protection part protrudes toward the rear side of the display unit 110, that is, the fixing part 1111 and the protection part form an included angle therebetween.

To simplify the structure of the attachment member 120, the contact surface may contact the fixing portion 1111. Thus, when the mounting member 120 is connected to the display unit 110, the contact surface is parallel to the touch glass.

The fixing portion 1111 and the touch glass have a spacing distance therebetween, and a display module of the display device and the like are sandwiched between the fixing portion 1111 and the touch glass. Different display units 110 may have different interval pitches according to models of the display units 110.

In order to make the planes of the two adjacent display units 110 coplanar, the height difference of the contact surfaces at the two ends of the mounting member 120 along the vertical direction of the touch glass is the same as the difference of the spacing distance between the two display units 110.

For example, the interval pitch of the first display unit is smaller than the interval pitch of the second display unit, and the contact surface of the attachment 120 corresponding to the first display unit is closer to the touch glass side than the other contact surface. Thus, when the two ends of the attachment member 120 are attached to the fixing portions 1111 of the two display units 110, the front walls of the touch glasses of the two display units 110 are coplanar, so as to avoid the situation that the touch signals of the infrared touch display device are disordered.

It can be understood that when the models of two adjacent display units 110 are the same, the fixing portions 1111 of the two display units 110 are coplanar, and then the two contact surfaces at the two ends of the attachment member 120 are also coplanar. In some embodiments, the mounting member 120 may be a flat plate structure, which is relatively simple.

Wherein, the mounting member 120 may be mounted on the rear wall surface of the rear case 111. Referring to fig. 5, in some possible embodiments, the mount 120 includes a first mount portion 121 and a second mount portion 122, and the second mount portion 122 is perpendicular to the first mount portion 121, that is, the mount 120 is approximately L-shaped, and the L-shaped mount 120 is generally disposed at an edge position of the tiled infrared touch display device 100.

The first mounting portion 121 is located at the rear side of the display unit 110 and is simultaneously mounted on the rear wall surface of the rear case 111 of two adjacent display units 110, for example, the first mounting portion 121 is simultaneously mounted on the fixing portion 1111 of two display units 110.

The display unit 110 is restricted by the contact between the first mounting portion 121 and the rear case 111. The second mounting portion 122 is simultaneously mounted on the side wall surfaces of the circumferential directions of two adjacent display units 110, for example, the second mounting portion 122 is simultaneously mounted on the top wall surfaces of two display units 110 or simultaneously mounted on the bottom wall surfaces of two display units 110.

Thus, the L-shaped mounting member 120 can limit two adjacent display units 110 at the same time, and prevent the display units 110 from tilting. The first mounting portion 121 is located at the rear side of the display unit 110, and the second mounting portion 122 is located at the top or the bottom of the display unit 110, so that the appearance of the tiled infrared touch display device 100 is slightly affected.

Referring to fig. 6, in some possible embodiments, the mounting member 120 further includes a third mounting portion 123, the third mounting portion 123 is connected to the second mounting portion 122, and the third mounting portion 123 is parallel to the first mounting portion 121, that is, the mounting member 120 is approximately U-shaped, and the U-shaped mounting member 120 is generally disposed at an edge position of the tiled ir-touch display apparatus 100.

The third attaching portion 123 is attached to the front wall surfaces of two adjacent display units 110 at the same time. In this way, when two adjacent display units 110 extend into the U-shaped mounting member 120, the third mounting portion 123 and the first mounting portion 121 both form a limit for the display units 110, so as to prevent the display units 110 from tilting.

Considering that the rear case 111 may be damaged during the process of connecting the fastening member to the rear case 111 when the display unit 110 is in the tilted state, for example, when the fastening member is a bolt, the screw hole of the rear case 111 may be damaged. Referring to fig. 7 to 9, in some embodiments, the tiled ir-touch display apparatus 100 further includes an adjusting assembly 130, which includes first adjusting parts 131, each display unit 110 is correspondingly provided with the first adjusting part 131, and the first adjusting part 131 is connected to the rear shell 111 and protrudes from the rear shell 111 to the rear side of the display unit 110.

In order to simplify the structure of the adjusting assembly 130, the embodiment takes the example that each display unit 110 is correspondingly provided with one first adjusting member 131 as an example.

The first adjusting member 131 may be a rod-shaped member, and one end of the first adjusting member 131 is connected to the rear case 111 and the other end is a free end and protrudes out of the rear case 111.

For the display unit 110 to be tilted, the first adjusting member 131 can be shifted correspondingly, the extending direction of the first adjusting member 131 forms an included angle with the touch glass, for example, the first adjusting member 131 can be tilted upward or tilted downward to protrude out of the rear housing 111, so as to be suitable for different positions to be installed and sizes of installation spaces of the tiled infrared touch display device 100.

Wherein the first adjusting member 131 may be welded to the rear case 111. In some possible embodiments, the first adjusting member 131 is detachably connected to the rear case 111, for example, the first adjusting member 131 is connected to the rear case 111 by a threaded fastener, a locking pin, or the like, so as to avoid excessive changes to the structure of the rear case 111 and reduce the manufacturing cost.

It is understood that the first adjusting member 131 is disposed on each display unit 110, and the fixing position and the extending direction of the first adjusting member 131 relative to the respective display unit 110 are the same. Then, when the display unit 110 is tilted, the first adjustment member 131 is correspondingly shifted.

In some embodiments, the adjusting assembly 130 includes a second adjusting member 132, the second adjusting member 132 is provided with a plurality of insertion portions 1321 arranged in parallel, the insertion portion 1321 is inserted into the first adjusting member 131, and the plurality of insertion portions 1321 extend in parallel. The plug portion 1321 may be a blind hole structure (not shown) or a through hole structure (shown in fig. 8) penetrating through the second adjuster 132, and the embodiment is not limited.

The number of the inserting portions 1321 is set as required, for example, when the second adjusting member 132 positions two adjacent display units 110, the number of the inserting portions 1321 is two. Then, when the two first adjusting members 131 are respectively plugged into the two plugging portions 1321, the extending directions of the two first adjusting members 131 are parallel, and correspondingly, the touch glasses of the two display units 110 are also parallel.

That is, when the display unit 110 is tilted, the tilted display unit 110 can be adjusted by inserting the first adjusting members 131 into the inserting parts 1321, so that the touch glasses of two adjacent display units 110 are in a parallel state.

At this time, the attachment 120 can be used to connect the two adjacent display units 110, and in the process of connecting the fastening member to the rear case 111, the relative positions of the two adjacent display units 110 in the vertical direction of the touch glass can be adjusted until the fixing portions 1111 of the two display units 110 are respectively abutted to the contact surfaces, and the planes of the two adjacent display units 110 are coplanar.

That is to say, through mutually supporting between the piece 120 of pasting, first regulating part 131, the second regulating part 132, can make things convenient for effectually adjust the relative position between two adjacent display element 110, avoid the infrared touch display device of concatenation formula to appear the condition that touch signal is in disorder, avoid backshell 111 to appear the damage simultaneously.

It is understood that the second adjustor 132 may have different sizes when the first adjustor 131 is provided at different positions of the rear case 111. For example, when the first adjusting member 131 is located at the middle position of the rear case 111, the second adjusting member 132 may have a size comparable to the width of the display unit 110.

In some embodiments, the first adjusting member 131 is located at an edge position of the rear case 111 (as shown in fig. 7 and 8) to reduce the size of the second adjusting member 132 and reduce the manufacturing cost of the second adjusting member 132. At this time, a plurality of connection structures connected to the first adjusting member 131 may be reserved at the circumferential edge position of the rear case 111, and when two display units 110 are arranged side by side, the first adjusting member 131 is arranged at the adjacent side position of the two display units 110.

In some embodiments, the adjustment assembly 130 further includes a first locking member 133, and the first locking member 133 passes through the second adjustment member 132 and is coupled to the first adjustment member 131. In this way, after two adjacent display units 110 are connected by the attachment 120, they can be fixed relatively by the first locking member 133 and the second adjusting member 132, so that two adjacent display units 110 can be maintained in a coplanar state.

The first locking member 133 may be a locking pin or the like. In some possible embodiments, the first locking member 133 is a threaded fastener, the second adjusting member 132 is provided with a communication portion 1323 for the threaded fastener to pass through, the communication portion 1323 is a through hole-shaped structure formed on the second adjusting member 132, the threaded fastener is screwed with the first adjusting member 131 through the communication portion 1323, that is, a threaded hole screwed with the first locking member 133 is formed on the first adjusting member 131, so that the first adjusting member 131 is easy to disassemble and assemble, and the second adjusting member 132 can be reliably connected to the first adjusting member 131, thereby avoiding positioning failure caused by separation of the second adjusting member 132.

It can be understood that, in the assembling process of the tiled infrared touch display device 100, before the display units 110 are installed, the first adjusting member 131 may be first fixed on the rear case 111, and then the display units 110 are respectively fixed on the positions to be installed, so as to avoid the limitation of the installation space, which is not beneficial to the assembly of the first adjusting member 131. Next, the second regulating member 132 is coupled to the first regulating member 131.

To facilitate guiding the first adjusting member 131 into the inserting part 1321, in some possible embodiments, an end of the inserting part 1321 facing the rear case 111 is provided with a guiding inclined surface 1322. Thus, even if the display unit 110 is tilted to cause the free end of the first adjusting member 131 to be shifted, the free end of the first adjusting member 131 can still be opposite to the guiding inclined surface 1322 by providing the guiding inclined surface 1322, so that the free end of the first adjusting member 131 can move along the guiding inclined surface 1322 until extending into the inserting part 1321, which is easy to assemble and convenient to operate.

The inclination angle of the introduction slant surface 1322 and the dimension of the introduction slant surface 1322 in the extending direction of the plug 1321 may be set as needed, for example, the inclination angle of the introduction slant surface 1322 is 45 °, and the dimension of the introduction slant surface 1322 in the extending direction of the plug 1321 is 0.2 to 0.3 times the dimension of the plug 1321 in the extending direction thereof.

It is understood that when the inserting part 1321 penetrates the second adjusting member 132, both ends of the inserting part 1321 may be provided with a guiding inclined surface 1322 (not shown), so that either end of the second adjusting member 132 can be used as a guiding end, and the operation is easy.

The first adjusting member 131 is perpendicular to the touch glass, and illustratively, the first adjusting member 131 is perpendicular to the fixing portion 1111, so as to be suitable for different types of display units 110. Meanwhile, the coupling stability between the first adjusting member 131 and the rear case 111 may also be improved.

In some embodiments, the first adjustment member 131 may include a first connection portion 1311 and a second connection portion 1312, the first connection portion 1311 is formed in a sheet shape and attached to the fixing portion 1111 such that a contact area between the first connection portion 1311 and the fixing portion 1111 is large, and the first connection portion 1311 is vertically connected to the second connection portion 1312, for example, the first connection portion 1311 and the second connection portion 1312 are welded to each other such that the first adjustment member 131 is stably connected to the fixing portion 1111.

In some possible embodiments, the second adjusting member 132 further comprises a retractable connecting portion (not shown) for connecting two adjacent plug portions 1321. In this way, when the second adjusting member 132 is applied to display units 110 of different models, for example, the tiled infrared touch display device 100 includes display units 110 of different models, the second adjusting member 132 can be extended or retracted according to the distance between two adjacent first adjusting members 131, and the applicability is high.

In some possible embodiments, the connecting portion includes a plurality of connecting arms sleeved inside and outside, the plurality of connecting arms can move relatively along the axial direction of the connecting portion, so as to achieve extension or shortening of the connecting portion, and the structure of the connecting portion is relatively simple.
