[0006] The thickness of the panel body is 3 mm.

[0007] The organic thin film is formed on the surface of the panel body through an organic coating process.

[0008] The fixing bracket includes a fitting strip fitted with the edge of the front frame, and a first connecting strip and a second connecting strip respectively vertically connected to both sides of the fitting strip, wherein the first connecting strip and the second connecting strip are in opposite directions; the first connecting strip is fixed to the front frame by screw locking; a plurality of rivets are fixed to the second connecting strip, and the rivets pass through positioning holes provided at the edge of the panel body to fix the panel body.

[0009] Preferably, the first connecting strip is provided with a plurality of through holes for screws to pass through.

[0010] Preferably, at least two fixing brackets are provided in the length direction of the front frame; and at least one fixing bracket is provided in the width direction of the front frame.

[0011] After adopting the above technical solution, the present invention has the following technical effects: The present invention is the first in the industry to use an acrylic writing panel instead of a tempered glass writing panel, which, on the one hand, reduces the overall weight of the whole machine and achieves the purpose of reducing weight and cost; on the other hand, the acrylic writing panel does not have the risk of self-explosion and is safer and more reliable when used; at the same time, an organic film is bonded to the surface of the panel body, which can increase the surface hardness of the writing panel from 2H to 8H, solving the problem of easy scratches on the acrylic surface; the fixed bracket is made of hardware material, which can make up for the problem of insufficient rigidity of the acrylic writing panel.

DETAILED DESCRIPTION

[0013] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0014] refer to Figure 1-4 As shown, the present invention discloses an infrared touch display device with an acrylic writing panel, comprising a front frame 1 of the infrared touch display device, a plurality of fixing brackets 2 fixed to the inner edge of the front frame 1, and a writing panel 3 whose edges are connected to the fixing brackets 2; The fixing bracket 2 is made of hardware material; The writing panel 3 includes a panel body 31 made of acrylic material and an organic film 32 attached to the front surface of the panel body 31 .

[0015] Through the above scheme, the present invention is the first in the industry to use an acrylic writing panel instead of a tempered glass writing panel. On the one hand, the overall weight of the whole machine is reduced, achieving the purpose of reducing weight and reducing costs. On the other hand, the acrylic writing panel does not have the risk of self-explosion, and is safer and more reliable when used. At the same time, the surface of the panel body 31 is bonded with an organic film 32, which can increase the surface hardness of the writing panel 3 from 2H to 8H, solving the problem of easy scratches on the acrylic surface. The fixed bracket 2 is made of hardware material, which can make up for the problem of insufficient rigidity of the acrylic writing panel.

[0016] Specific embodiments of the present invention are shown below.

[0017] The panel body 31 has a thickness of 3 mm.

[0018] The organic thin film 32 is formed on the surface of the panel body 31 through an organic coating process.

[0019] The fixing bracket 2 comprises a fitting strip 21 fitted with the edge of the front frame 1, and a first connecting strip 22 and a second connecting strip 23 respectively connected vertically to the two sides of the fitting strip 21, and the first connecting strip 22 and the second connecting strip 23 are in opposite directions; the first connecting strip 22 is fixed to the front frame 1 by screw locking; the second connecting strip 23 is fixed with a plurality of rivets 4, and the rivets 4 pass through the positioning holes 311 provided at the edge of the panel body 31 to fix the panel body 31. During installation, the fitting strip 21 realizes the installation and positioning of the fixing bracket 2, the first connecting strip 22 is fixed by screw locking, and then the positioning holes 311 of the writing panel 3 are aligned with the corresponding rivets 4, and the edges of the writing panel 3 are hooked by the rivets 4 to realize the installation and fixing of the writing panel 3 on the front frame 1.

[0020] Furthermore, the first connecting bar 22 is provided with a plurality of through holes 221 for screws to pass through.

[0021] Meanwhile, at least two fixing brackets 2 are provided in the length direction of the front frame 1 ; and at least one fixing bracket 2 is provided in the width direction of the front frame 1 .

[0022] Taking a conventional 86-inch infrared touch display device as an example, the size of the 86-inch writing panel is 1940×1110mm, the weight of conventional 3mm thick tempered glass is 16kg, and the weight of 3mm acrylic plate is 7.5kg. In comparison, the weight of a conventional 86-inch infrared touch display device using tempered glass is 62kg, while the weight of the device of the present invention of the same size is 51.5kg, which is reduced by 8.5kg, and the weight reduction ratio reaches 13.7%, which has great advantages in saving costs in design, production, transportation, etc.

[0023] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
