Description

Technical Field

[0001] This utility model relates to the field of resistive touch screen technology, specifically a waterproof resistive touch screen. Background Technology

[0002] Resistive touchscreens, with their mature technology, low cost, and high touch accuracy, are widely used in many fields, such as industrial control, medical equipment, and public information retrieval. However, in practical use, existing resistive touchscreens have some problems that urgently need to be solved.

[0003] From a physical protection perspective, conventional resistive touchscreens lack effective cushioning structures when subjected to impacts or drops. Internal components are easily damaged by the impact, leading to touchscreen malfunctions or display abnormalities, affecting their lifespan and reliability. This not only increases maintenance costs but may also cause inconvenience or even safety hazards in critical applications. Regarding waterproofing, many resistive touchscreens struggle to meet the demands of complex environments. Once exposed to water, moisture easily seeps in, corroding critical components such as the light-emitting layer and electrode layer, causing short circuits, open circuits, and other problems, rendering the touchscreen unusable. Especially in humid environments or applications where water contact is possible, such as outdoor equipment and medical devices, existing waterproofing technologies cannot provide reliable protection. Furthermore, as industries increasingly demand higher performance from touchscreens, they require both good impact resistance and reliable waterproofing. Existing technologies often fail to balance these two aspects, making it difficult to meet market demands for high-performance touchscreens. Therefore, those skilled in the art have developed a waterproof resistive touchscreen to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof resistive touchscreen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waterproof resistive touchscreen includes a housing, a hydrophobic layer, a first buffer groove, and a second buffer groove. The housing has several first buffer grooves on its front and rear sides and on its left and right sides. Each first buffer groove contains a movably connected ball bearing, which is confined within the first buffer groove. Each first buffer groove also contains a fixedly connected return spring, which contacts but is not connected to the ball bearing. The lower end of the housing has several second buffer grooves, each second buffer groove contains a movably connected ball bearing, which is confined within the second buffer groove. Each second buffer groove also contains a fixedly connected return spring, whose lower end contacts but is not connected to the ball bearing.

[0007] As a further embodiment of this utility model: a back plate is fixedly connected inside the outer shell, and a light-emitting layer is fixedly connected to the top of the back plate.

[0008] As a further embodiment of this utility model: a lower electrode layer is fixedly connected to the top of the light-emitting layer, a pressure-sensitive layer is fixedly connected to the top of the lower electrode layer, and a panel is fixedly connected to the top of the pressure-sensitive layer.

[0009] As a further embodiment of this utility model: a hydrophobic layer is fixedly connected to the top of the panel, wherein the hydrophobic layer is a polysiloxane material and has a transparent structure, and a water-proof ring is adhered to the surface of the hydrophobic layer, wherein the water-proof ring is a silicone structure.

[0010] As a further improvement of this utility model: a water-blocking layer is provided around the back plate, wherein the water-blocking layer is made of resin material, and the water-blocking layer is thermally fused to the back plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Strong impact resistance: The front, back, left and right sides and bottom of the shell are respectively equipped with buffer grooves with ball bearings and return springs. When the touch screen is dropped or hit, the ball bearings first contact the ground or the object that collides. The impact force is absorbed by compressing the return spring. At the same time, the ball bearings rotate to disperse the impact force, which can effectively reduce the damage to the touch screen, improve its impact resistance and extend its service life.

[0013] 2. Excellent waterproof performance: The hydrophobic layer at the top of the panel is made of polysiloxane material, which has good hydrophobicity and can prevent water penetration; the silicone water barrier ring on the surface of the hydrophobic layer can further prevent water from entering from the edge; the resin water-blocking layer around the back panel is tightly connected to the back panel through heat fusion, preventing water intrusion in all directions and protecting the internal light-emitting layer, lower electrode layer, pressure-sensitive layer and other components, ensuring that the touch screen can work normally in a humid environment.

[0014] 3. Reasonable structural design: The components are compactly arranged and work together. From the external protective structure to the internal functional layer, everything has been carefully designed. The combination of the buffer structure and the waterproof structure takes into account both physical damage protection and waterproof requirements, making the overall performance of the touch screen more perfect.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 In this embodiment of the present invention, a waterproof resistive touchscreen includes a shell 1, a hydrophobic layer 8, a first buffer groove 2, and a second buffer groove 5. The shell 1 has several first buffer grooves 2 on its front and rear sides and left and right sides. A ball bearing 3 is movably connected to each first buffer groove 2, and the ball bearing 3 is confined within the first buffer groove 2. A return spring 4 is fixedly connected to each first buffer groove 2, and the return spring 4 contacts the ball bearing 3 but is not connected to it. The lower end of the shell 1 has several second buffer grooves 5, each second buffer groove 5 having a ball bearing 6 movably connected to it, and the ball bearing 6 is confined within the second buffer groove 5. A return spring 7 is fixedly connected to each second buffer groove 5. The lower end of spring 2 7 is in contact with ball 2 6, but not connected. A back plate 13 is fixedly connected inside the outer shell 1. A light-emitting layer 12 is fixedly connected to the top of the back plate 13. A lower electrode layer 11 is fixedly connected to the top of the light-emitting layer 12. A pressure-sensitive layer 10 is fixedly connected to the top of the lower electrode layer 11. A panel 9 is fixedly connected to the top of the pressure-sensitive layer 10. A hydrophobic layer 8 is fixedly connected to the top of the panel 9. The hydrophobic layer 8 is made of polysiloxane material and is transparent. A water-proof ring 15 is bonded to the surface of the hydrophobic layer 8. The water-proof ring 15 is made of silicone. A water-blocking layer 14 is provided around the back plate 13. The water-blocking layer 14 is made of resin material and is thermally fused to the back plate 13.

[0022] The working principle of this invention is as follows: When the touchscreen falls to the ground, the ball bearings around its outer shell 1 and at its bottom will first contact the ground. After being impacted by the ground, the ball bearings will compress the corresponding return springs. The deformation of the return springs absorbs the impact force, thus playing a buffering role and reducing the damage to the touchscreen caused by the fall. When the touchscreen is hit by a collision, the ball bearings will also be subjected to the impact force. On the one hand, the ball bearings will compress the return springs to absorb the impact energy; on the other hand, the impact force will drive the ball bearings to rotate, changing the direction of the impact force and further dispersing the impact force, reducing damage to the overall structure of the touchscreen. In addition to its waterproofing properties, the touchscreen achieves waterproofing through a multi-layer structure design. The hydrophobic layer 8 at the top of the panel 9 is made of polysiloxane material, which is hydrophobic and prevents water from easily staying or penetrating its surface. The water-resistant ring 15 on the surface of the hydrophobic layer 8 is made of silicone, which can further prevent water from entering from the edges. The water-resistant layer 14 around the back panel 13 is made of resin material and is tightly bonded to the back panel 13 by heat fusion to prevent water from entering from the sides of the back panel 13. This protects the internal components of the touchscreen, such as the light-emitting layer 12, the lower electrode layer 11, and the pressure-sensitive layer 10, from water damage and ensures the normal operation of the touchscreen.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
