Description

Technical Field

[0001] This utility model relates to the field of resistive touch screen technology, and in particular to a multi-point resistive touch screen with a dustproof structure. Background Technology

[0002] A multi-touch resistive touchscreen with a dustproof structure is an input device that incorporates a specially designed dustproof feature into a traditional multi-touch resistive touchscreen. It is used for information interaction and display in electronic devices, featuring multi-touch functionality, capable of simultaneously recognizing multiple touch points, and supporting interaction methods such as zooming, rotation, and multi-finger operation. By adding dustproof structures, such as a sealed frame, dustproof strips, and a breathable dustproof film, dust is prevented from entering the screen from the edges, interlayer gaps, or ventilation areas. This protects the conductive layer, circuitry, and other critical components from dust corrosion, maintains stable touch performance and display effects, extends the screen's lifespan, and allows it to operate normally in dusty environments.

[0003] In existing technologies, multi-point resistive touchscreens are typically attached to the device frame using dustproof and waterproof adhesive to ensure their waterproof and dustproof performance. Installing these screens requires highly skilled and experienced operators. Precise calibration using specialized tools is necessary to align the screen and frame precisely; even minor deviations can affect touch sensitivity and display quality, leading to inaccurate touch input, localized display abnormalities, and potentially loose connections between the frame and screen, reducing device protection and shortening lifespan. This complex process results in low installation efficiency, significantly extended product assembly cycles, and substantial increases in labor costs. Furthermore, in large-scale production, variations in operator skill levels make it difficult to guarantee consistent product quality. The challenging positioning of the resistive touchscreen against the frame during installation further complicates the work, leading to low efficiency and complex positioning procedures.

[0004] Therefore, it is necessary to provide a new multi-point resistive screen with a dustproof structure to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-point resistive screen with a dustproof structure.

[0006] The present invention provides a multi-point resistive screen with a dustproof structure, comprising: a resistive screen body and a mounting frame device, wherein the mounting frame device has mounting grooves on all four sides, and the outer side of the resistive screen body extends into the four mounting grooves respectively.

[0007] The mounting frame device includes a positioning frame and a locking frame. Four mounting slots are located on three inner sides of the positioning frame and one inner side of the locking frame, respectively. A sealing strip is provided on the side of the positioning frame near the locking frame, and a sealing groove is provided on the side of the locking frame near the positioning frame. The sealing strip extends into the sealing groove, and the outer side of the sealing strip is in contact with the inner wall of the sealing groove. The four outer sides of the resistive screen body are in contact with the inner walls of the four mounting slots, respectively. A connecting adhesive layer is applied to both sides of the resistive screen body near the positioning frame and the locking frame, as well as at the connection between the positioning frame and the locking frame.

[0008] Preferably, the adhesive layer material is polyurethane sealant.

[0009] Preferably, the resistive touchscreen body includes: a bottom layer, a lower conductive layer, an insulating layer, an upper conductive layer, and a protective layer, wherein the bottom layer, the lower conductive layer, the insulating layer, the upper conductive layer, and the protective layer are connected in sequence, and the outer sides of the bottom layer and the protective layer are respectively attached to the inner opposite sides of the four mounting slots.

[0010] Preferably, the bottom layer, the lower conductive layer, the insulating layer, the upper conductive layer, and the protective layer are connected by an adhesive layer.

[0011] Preferably, the adhesive layer material is silicone adhesive.

[0012] Preferably, the bottom layer material is soda-lime glass, and the materials of the lower conductive layer and the upper conductive layer are both graphene two-dimensional carbon materials.

[0013] Preferably, the insulating layer material is a polyester film material.

[0014] Preferably, the protective layer material is tempered glass.

[0015] Compared with related technologies, the multi-point resistive screen with a dustproof structure provided by this utility model has the following beneficial effects:

[0016] In practical use, the resistive touchscreen body is slid into the positioning frame along the mounting slots on both sides. The sealing groove on the locking frame aligns with the sealing strip on the positioning frame, ensuring the sealing strip fully extends into the sealing groove. Then, a connecting adhesive layer is applied to the edges of the resistive touchscreen body near the positioning and locking frames. This adhesive layer connects the resistive touchscreen to the positioning and locking frames. A connecting adhesive layer is also applied at the connection point between the positioning and locking frames. When using this device, operators do not need high-precision positioning equipment when installing the resistive touchscreen and frame; they only need to insert the resistive touchscreen body into the mounting slot inside the positioning frame. This improves operator efficiency and simplifies installation, increasing accuracy. After installation, the sealing strip, sealing groove, and connecting adhesive layer enhance the device's waterproof and dustproof sealing performance, resulting in a more stable connection.

A connecting adhesive layer 6 is applied to the sides of the resistive screen body near the positioning frame 1 and the locking frame 2, as well as at the connection between the positioning frame 1 and the locking frame 2. The material of the connecting adhesive layer 6 is polyurethane sealant.

[0028] It should be noted that the sealing strip 4 provided on the positioning frame 1 and the sealing groove 5 provided on the engaging frame 2 have their outer side wall fitting against the inner side wall of the sealing groove 5. In use, the sealing strip 4 is inserted into the sealing groove 5 to perform initial installation and fixation of the device. Then, the connecting adhesive layer 6 is applied to both sides of the resistive screen body near the positioning frame 1 and the engaging frame 2, as well as at the connection between the positioning frame 1 and the engaging frame 2. The material of the connecting adhesive layer 6 is polyurethane sealant, which further increases the sealing performance of the device in use, making the device connection tighter. In addition, polyurethane sealant has good waterproof and dustproof properties, giving the device a dustproof function.

[0029] The resistive touch screen body includes: a bottom layer 7, a lower conductive layer 8, an insulating layer 9, an upper conductive layer 10, and a protective layer 11. The bottom layer 7, the lower conductive layer 8, the insulating layer 9, the upper conductive layer 10, and the protective layer 11 are connected in sequence. The outer sides of the bottom layer 7 and the protective layer 11 are respectively attached to the inner opposite sides of the four mounting slots 3.

The aforementioned lower conductive layer 8 and upper conductive layer 10 have good conductivity. When the resistive touch screen is touched during use, the lower conductive layer 8 and upper conductive layer 10 can realize the recognition of the touch position of the resistive touch screen. The aforementioned insulating layer 9 is used to optimize the bonding process between the lower conductive layer 8 and the upper conductive layer 10, and can effectively isolate the upper conductive layer 10 and the lower conductive layer 8. The aforementioned protective layer 11 has good anti-friction and anti-drop properties, and can provide protection for other parts during use, so that the device has a longer service life.

[0031] The bottom layer 7, the lower conductive layer 8, the insulating layer 9, the upper conductive layer 10, and the protective layer 11 are connected by an adhesive layer 12, which is made of silicone adhesive.
