Description

Technical Field

[0001] This utility model relates to industrial automation equipment, and more particularly to a protective device for a removable touch screen of an electrical control cabinet. Background Technology

[0002] Human-machine interface (HMI) touchscreens, as a crucial component of industrial automated production equipment, are the core component for realizing human-machine interaction. Through touchscreens, operators can monitor equipment operating status in real time, record and analyze production data, and directly control the operation or shutdown of production equipment. However, due to the complex environment of industrial sites, dust, oil, and cleaning agents can damage touchscreens during maintenance or deep cleaning. Existing touchscreen protection methods mostly employ temporary or fixed designs, such as covering with plastic film, applying transparent tape, or using fixed protective covers. However, these protective methods and devices all have certain shortcomings:

[0003] When using plastic film or tape, these methods are typically for single use, increasing maintenance costs and environmental burden. Furthermore, tape can leave adhesive residue on the touchscreen surface, affecting cleaning and potentially damaging the screen. Fixed protective covers are heavy, time-consuming to install and remove, and can easily cause wear and tear on the device's outer surface.

[0004] When a fixed protective cover is used, it is made of rigid material, is heavy, and takes a long time to install and remove, which can easily cause wear and tear on the outer surface of the equipment. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a protective device for a removable electrical control cabinet touch screen that is simple in structure, easy to remove and install, portable, lightweight, and reusable, protecting the touch screen from dust, oil, cleaning agents and other potential damage.

[0006] This utility model is achieved through the following technical solution:

[0007] A protective device for a removable touchscreen on an electrical control cabinet is provided. The touchscreen protrudes from the surface of the electrical control cabinet. The protective device includes a cover, which comprises a transparent protective film, a positioning frame, and a connecting frame arranged sequentially from front to back. The transparent protective film is a polycarbonate film or an acrylic film. The positioning frame is located on the rear side of the transparent protective film near the edge and is a flexible frame. The connecting frame is a soft magnetic strip frame. The transparent protective film, the positioning frame, and the connecting frame together form a receiving space for accommodating the touchscreen. The cover covers the touchscreen and is magnetically attracted to the surface of the electrical control cabinet through the connecting frame. The touchscreen is located in the receiving space of the cover.

[0008] As a preferred embodiment of the above-mentioned protective device, the positioning frame is a rectangular frame, and the inner sidewall of the positioning frame matches the outer sidewall of the touch screen.

[0009] As a preferred embodiment of the above-mentioned protective device, the positioning frame is a silicone frame or an EVA foam frame.

[0010] As a preferred embodiment of the above-mentioned protective device, the connecting frame and the positioning frame have the same shape, and the sum of the thicknesses of the connecting frame and the positioning frame is equal to the thickness of the touch screen protruding from the surface of the electrical control cabinet.

[0011] As a preferred embodiment of the above-mentioned protective device, the transparent protective film is connected to the positioning frame, and the positioning frame is connected to the connecting frame by adhesive.

[0012] This invention has the following advantages over the prior art:

[0013] This utility model provides a protective device for a removable touchscreen in an electrical control cabinet. The cover is magnetically attached to the surface of the control cabinet via a connecting frame, enabling convenient installation and removal. Simultaneously, the cover provides waterproof and dustproof protection for the touchscreen and also functions as a touch film, allowing touch operation without removing the cover. This dual-purpose device is low-cost and suitable for large-scale deployment. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0021] See Figures 1 to 5 This embodiment discloses a protective device for a removable touchscreen of an electrical control cabinet. The electrical control cabinet 1 has a touchscreen protruding from its surface. The protective device includes a cover 2, which comprises a transparent protective film 3, a positioning frame 4, and a connecting frame 5 arranged sequentially from front to back. The transparent protective film 3 is connected to the positioning frame 4, and the positioning frame 4 is connected to the connecting frame 5, respectively, by adhesive bonding. The transparent protective film 3 is a polycarbonate film or an acrylic film, providing dust and water protection while remaining visible, and can also be used as a touchscreen. The positioning frame 4 is located on the rear side of the transparent protective film 3 near the edge. The positioning frame 4 is a flexible frame, which can be made of silicone or EVA foam. The connecting frame 5 is a soft magnetic strip frame. The transparent protective film 3, the positioning frame 4, and the connecting frame 5 together form a receiving space 6 for accommodating the touchscreen. The cover 2 covers the touchscreen and is magnetically attracted to the surface of the electrical control cabinet 1 through the connecting frame 5. The touchscreen is located within the receiving space 6 of the cover 2.

[0022] The positioning frame 4 is a rectangular frame, and its inner sidewall matches the outer sidewall of the touchscreen. The connecting frame 5 has the same shape as the positioning frame 4, and the sum of the thicknesses of the connecting frame 5 and the positioning frame 4 is equal to the thickness of the touchscreen protruding from the surface of the control cabinet 1, ensuring that the transparent protective film 3 can adhere tightly to the touchscreen surface, facilitating touch operation through the transparent protective film 3. Furthermore, the entire cover 2 is made of lightweight materials, reducing its overall weight and facilitating installation and removal.

[0023] In use, the cover 2 is placed over the touchscreen of the electrical control cabinet 1, so that the touchscreen is located within the housing space 6 of the cover 2. The positioning frame 4 is located around the touchscreen and is magnetically attached to the surface of the electrical control cabinet 1 via the connecting frame 5. The cover 2 provides waterproof and dustproof protection for the touchscreen and also functions as a touch film, allowing touch operation through the transparent protective film 3, thus serving two purposes. When the protective device is no longer needed, the cover 2 can be easily removed, making the operation very convenient and quick.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
