Description

Technical Field

[0001] This utility model relates to the field of touch screens, and specifically to a touch screen with a protective structure. Background Technology

[0002] Touchscreens, as a widely used input / output device, have been deeply integrated into consumer electronics, industrial control, medical equipment, and public information terminals. Their core value lies in enabling efficient operation through an intuitive human-computer interaction interface. These products typically consist of a display module and a sensing layer stacked together. Users can directly input commands using their fingers or a stylus. However, traditional designs often prioritize touch sensitivity and display quality, resulting in significant shortcomings in optimizing the physical protective structure.

[0003] The touchscreen consists of a glass panel, a transducer, and a reflective array. The glass panel is made of chemically strengthened glass with reflective stripes engraved on the edges to conduct ultrasonic waves. The transducer includes a transmitter that converts electrical signals into ultrasonic waves and a receiver that detects the attenuated ultrasonic signals. The reflective array consists of fine grooves on the edges of the glass that guide ultrasonic waves to cover the entire screen.

[0004] Existing protective devices of this type typically employ an integral frame structure. When subjected to a drop or collision, the impact energy is directly transmitted to the screen assembly through the rigid frame, causing the glass panel to crack due to stress concentration. The sealing design at the joints often relies on a single-layer sealing gasket. As the service life extends, the gasket ages and deforms, easily forming tiny gaps that allow dust or liquid to seep into the device along the joint surface, leading to decreased touch module sensitivity or circuit corrosion. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned defects and provide a touch screen with a protective structure. By using an anti-slip frame and a cushioning pad, it solves the technical problem that in the prior art, when an object is dropped or collided, the impact energy is directly transmitted to the screen assembly through the rigid frame, causing the glass panel to crack due to stress concentration.

[0006] The objective of this utility model is achieved through the following means:

[0007] A touchscreen with a protective structure includes a protective frame. A screen assembly, which is a touchscreen, is mounted at the center of the front of the protective frame. A sealing strip is added at the connection between the protective frame and the screen assembly. A dustproof flip cover is rotatably connected to the front of the protective frame. The back of the dustproof flip cover is tightly fitted to the front of the screen assembly. Rubber buffer pads are installed at the four outer corners of the protective frame. Mounting holes are evenly distributed around the front of the protective frame. The protective frame consists of a protective top plate, protective side plates, and a protective bottom plate. Rotating grooves are formed on both sides of the upper surface of the protective top plate. Side grooves are formed on both sides of the inner wall of the rotating grooves. Side protrusions are inserted into the inner cavities of the side grooves. A rotating shaft is rotatably connected to the inner side of the side protrusions. The rotating shaft is connected to the upper surface of the dustproof flip cover. An annular retaining plate is slidably fitted to the upper surface of the side protrusions. The annular retaining plate is rotatably connected to the upper surface of the protective top plate. The protective top plate, protective side plates, and protective bottom plate are connected to form an annular frame structure. The center of the front of the protective frame has reserved space for the installation of the screen assembly, and the back is fixedly connected to an external device through mounting holes.

[0008] The screen assembly is embedded in the central groove on the front of the protective frame, and the gap between the screen assembly and the protective frame is filled with sealing strips to form a sealed structure to block external liquids or dust.

[0009] Insert the two ends of the rotating shaft on the upper surface of the dust cover into the rotating groove of the protective top plate, so that the side protrusions on both sides of the rotating shaft are embedded in the side grooves, thus completing the rotating connection between the dust cover and the protective frame. Slide the annular plate to cover the top of the side protrusions to prevent the rotating shaft from coming out.

[0010] Flip the dust cover so that its back side fits against the front side of the screen assembly. The ring plate remains in place to lock the flip angle. Slide the ring plate to release the limit of the opposite side protrusion. Flip the dust cover to the desired angle. The ring plate resets to fix the current opening angle.

[0011] When the protective frame is subjected to external impact, the rubber buffer pads at its four outer corners absorb the impact energy through deformation, reducing the vibration transmitted to the screen components.

[0012] Furthermore, the outer side of the sealing strip is provided with positioning holes, and positioning posts are installed on the inner sides of the protective top plate, protective side plate and protective bottom plate, and the positioning posts are inserted and connected to the positioning holes.

[0013] Align the positioning holes on the outer side of the sealing strip with the positioning posts on the inner sides of the protective top plate, protective side plate, and protective bottom plate. Insert the positioning posts into the positioning holes to complete the initial fixing of the sealing strip and the protective components.

[0014] Furthermore, the upper and lower parts of the front side of the protective side plate are provided with snap-fit ​​grooves, and the front end of the inner cavity of the snap-fit ​​groove is slidably connected to an external sliding plate.

[0015] In the snap-fit ​​grooves on the upper and lower parts of the front of the protective side panel, push the external connecting slide plate along the front end of the snap-fit ​​groove to adjust its position to fit the external connecting parts or reserve the operation.

[0016] Furthermore, the upper and lower parts of the inner side of the protective side plate are provided with insertion interfaces, and the insertion interfaces are connected to the snap-fit ​​slots.

[0017] The corresponding structure can be inserted into the slot via the interface for snap-in operation.

[0018] Furthermore, the inner cavity of the snap-fit ​​groove is slidably connected to a post, and the post is connected to an external sliding plate, and a compression spring is connected between the end of the post and the inner wall of the snap-fit ​​groove.

[0019] The external connecting slide slides along the inner cavity of the snap-fit ​​groove on the front of the protective side plate, causing the external connecting slide to drive the connected pin to move synchronously in the snap-fit ​​groove and compress the spring.

[0020] Furthermore, plug-in blocks are installed on both sides of the lower surface of the protective top plate and the protective bottom plate, and the plug-in blocks correspond to the plug-in interface in position and shape. Semicircular grooves are opened on the surface of the protective top plate, the protective bottom plate and the side protrusions, and two adjacent sets of semicircular grooves form a complete circular groove. The annular card plate is set in the inner cavity of the complete circular groove.

[0021] Align the semi-circular grooves on the surface of the protective top plate, protective bottom plate and side protrusions, so that two adjacent sets of semi-circular grooves are combined to form a complete circular groove. Then, insert the annular clamping plate into the inner cavity of the complete circular groove to fix the protective components.

[0022] The beneficial effects of this utility model are:

[0023] The protective frame adopts a combination design of a split protective top plate, protective side plate and protective bottom plate. When encountering external impact, the modular structure can disperse stress and form a three-dimensional buffer system with the four corner rubber buffer pads to effectively absorb the impact energy generated by the drop or collision, and prevent the screen components from breaking or failing due to direct force.

[0024] The sealing strip at the connection between the protective frame and the screen assembly forms the first line of defense. Its elastic sealing properties can completely prevent dust and liquids from entering the device along the seam, thus preventing touch response delays or display module corrosion caused by contaminant deposits.

[0025] The dustproof flip cover's rotating protective structure achieves a dual protection mechanism: when closed, the flip cover surface and the screen assembly form a physical isolation layer, which can resist scratches from sharp objects and accidental impacts. Its tight fit design with the touch screen on the back further eliminates gaps and prevents tiny particles from entering the operating interface. Attached Figure Description

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] In this embodiment, refer to Figures 1 to 6The specific implementation of the touch screen with a protective structure includes a protective frame 1, a screen assembly 3 installed at the center of the front of the protective frame 1, a sealing strip 4 added at the connection between the protective frame 1 and the screen assembly 3, a dustproof flip cover 2 rotatably connected to the front of the protective frame 1, the back of the dustproof flip cover 2 tightly fitting the front of the screen assembly 3, rubber buffer pads 5 installed at the four outer corners of the protective frame 1, and mounting holes 6 evenly opened around the front of the protective frame 1. The protective frame 1 is composed of a protective top plate 7, protective side plates 8 and a protective bottom plate 9. Rotating grooves 18 are opened on both sides of the upper surface of the protective top plate 7, and side grooves 23 are opened on both sides of the inner wall of the rotating grooves 18. Side protrusions 22 are inserted into the inner cavity of the side grooves 23, and a rotating shaft 21 is rotatably connected to the inner side of the side protrusions 22. The rotating shaft 21 is connected to the upper surface of the dustproof flip cover 2, and an annular retaining plate 20 is slidably attached to the upper surface of the side protrusions 22. The annular retaining plate 20 is rotatably connected to the upper surface of the protective top plate 7. The protective top plate 7, protective side plate 8 and protective bottom plate 9 are connected to form a ring frame structure. The front center of the protective frame 1 is reserved for the installation space of the screen assembly 3, and the back is fixedly connected to the external equipment through the mounting holes 6.

[0035] The screen assembly 3 is embedded in the central groove on the front of the protective frame 1, and the gap between the screen assembly 3 and the protective frame 1 is filled by the sealing strip 4 to form a sealed structure to block external liquids or dust.

[0036] Insert both ends of the rotating shaft 21 on the upper surface of the dust cover 2 into the rotating groove 18 of the protective top plate 7, so that the side protrusions 22 on both sides of the rotating shaft 21 are embedded in the side grooves 23, thus completing the rotational connection between the dust cover 2 and the protective frame 1. By sliding the annular plate 20, it covers the top of the side protrusions 22 to prevent the rotating shaft 21 from coming out.

[0037] Flip the dustproof cover 2 so that its back side fits against the front side of the screen assembly 3. The ring plate 20 remains in place to lock the flip angle. Slide the ring plate 20 to release the limit of the opposite side protrusion 22. Flip the dustproof cover 2 to the desired angle. The ring plate 20 resets to fix the current opening angle.

[0038] When the protective frame 1 is subjected to external impact, the rubber buffer pads 5 at its four outer corners absorb the impact energy through deformation, reducing the vibration transmitted to the screen assembly 3.

[0039] The protective frame 1 is assembled from the split-design protective top plate 7, protective side plate 8 and protective bottom plate 9, which facilitates partial replacement and maintenance; together with the rubber buffer pad 5, it can resist external impact and vibration at the same time, and extend the service life of the screen assembly 3.

[0040] A sealing strip 4 is provided at the connection between the protective frame 1 and the screen assembly 3. When the dustproof flip cover 2 is closed, it is directly attached to the front of the screen assembly 3 to form a double sealing barrier, which effectively prevents liquid or dust from entering and is suitable for high dust or humid environments.

[0041] like Figure 2 and Figure 3 As shown, the outer side of the sealing strip 4 has positioning holes 10, and positioning posts 11 are installed on the inner sides of the protective top plate 7, protective side plate 8, and protective bottom plate 9, with the positioning posts 11 inserted into the positioning holes 10. Aligning the positioning holes 10 on the outer side of the sealing strip 4 with the positioning posts 11 on the inner sides of the protective top plate 7, protective side plate 8, and protective bottom plate 9, and inserting them to fully embed the positioning posts 11 into the positioning holes 10, completes the initial fixation of the sealing strip 4 to the protective components. The insertion connection between the positioning holes 10 and the positioning posts 11 ensures precise alignment between the sealing strip 4 and the protective components, avoiding sealing failure caused by installation deviations. The positioning structure simplifies the installation process, improves assembly efficiency, and enhances the fixing stability of the sealing strip 4, preventing it from falling off or shifting during use.

[0042] like Figure 4 As shown, the upper and lower parts of the front of the protective side panel 8 are provided with snap-fit ​​grooves 12, and the front end of the inner cavity of the snap-fit ​​groove 12 is slidably connected to an external connecting slide plate 15. Within the snap-fit ​​grooves 12 on the upper and lower parts of the front of the protective side panel 8, the external connecting slide plate 15 can be pushed to slide along the front end of the inner cavity of the snap-fit ​​groove 12, adjusting its position to accommodate external connecting components or reserve operating space. The sliding connection design between the external connecting slide plate 15 and the snap-fit ​​groove 12 allows for flexible adjustment of the position of the external connecting slide plate 15 according to actual needs, improving the adaptability and ease of operation of the protective side panel 8. The sliding adjustment function provides redundant space for the connection or disassembly of external components, reducing installation difficulty and enhancing the scalability of the structure. The upper and lower parts of the inner side of the protective side panel 8 are provided with insertion interfaces 13, and the insertion interfaces 13 communicate with the snap-fit ​​grooves 12. The corresponding structure can be inserted into the snap-fit ​​slot 12 via the insertion interface 13 for snap-fit ​​operation. The connection design between the insertion interface 13 and the snap-fit ​​slot 12 enables dual locking in both the lateral and longitudinal directions through a single operation, reducing the number of connecting parts and optimizing structural compactness. A pin 14 is slidably connected to the inner cavity of the snap-fit ​​slot 12, and the pin 14 is connected to the outer connecting slide plate 15. A compression spring 16 is connected between the end of the pin 14 and the inner wall of the snap-fit ​​slot 12. The outer connecting slide plate 15 slides along the inner cavity of the snap-fit ​​slot 12 on the front of the protective side plate 8, causing the outer connecting slide plate 15 to drive the connected pin 14 to move synchronously within the snap-fit ​​slot 12, compressing the compression spring 16. The combined design of the compression spring 16 and the pin 14 ensures that the pin 14 remains in the inserted state through an elastic reset function, effectively resisting external vibration or impact and improving the stability and durability of the connection structure.

[0043] like Figure 5 As shown, plug-in blocks 17 are installed on both sides of the lower surface of the protective top plate 7 and the protective bottom plate 9. The plug-in blocks 17 correspond to the plug-in interfaces 13 in position and shape. Semicircular grooves 19 are formed on the surfaces of the protective top plate 7, the protective bottom plate 9, and the side protrusions 22. Adjacent sets of semicircular grooves 19 form a complete circular groove. An annular retaining plate 20 is set in the inner cavity of the complete circular groove. The semicircular grooves 19 on the surfaces of the protective top plate 7, the protective bottom plate 9, and the side protrusions 22 are aligned so that adjacent sets of semicircular grooves 19 combine to form a complete circular groove. Then, the annular retaining plate 20 is embedded into the inner cavity of the complete circular groove to fix the protective components. This facilitates the disassembly and assembly of the dustproof flip cover 2 and the protective top plate 7, while ensuring connection stability.

[0044] The usage process of a touch screen with a protective structure in this embodiment is as follows: The protective top plate 7, the protective side plate 8 and the protective bottom plate 9 are assembled by the corresponding cooperation of the plug block 17 and the plug interface 13 to form a protective frame 1 with a ring frame structure. The front center of the protective frame 1 reserves the installation space of the screen assembly 3, and the back is fixedly connected to the external device through the mounting hole 6.

[0045] The screen assembly 3 is embedded in the central groove on the front of the protective frame 1. The gap between the screen assembly 3 and the protective frame 1 is filled by the sealing strip 4. The positioning hole 10 on the outer side of the sealing strip 4 is inserted and connected to the positioning post 11 on the inner side of the protective top plate 7, the protective side plate 8 and the protective bottom plate 9 to form a sealing structure to block external liquids or dust.

[0046] Insert both ends of the rotating shaft 21 on the upper surface of the dust cover 2 into the rotating groove 18 of the protective top plate 7, so that the side protrusions 22 on both sides of the rotating shaft 21 are embedded in the side grooves 23, thus completing the rotational connection between the dust cover 2 and the protective frame 1. By sliding the annular plate 20, it covers the top of the side protrusions 22 to prevent the rotating shaft 21 from coming out.

[0047] Flip the dustproof cover 2 so that its back side fits against the front side of the screen assembly 3. The ring plate 20 remains in place to lock the flip angle. Slide the ring plate 20 to release the limit of the opposite side protrusion 22. Flip the dustproof cover 2 to the desired angle. The ring plate 20 resets to fix the current opening angle.

[0048] When the protective frame 1 is subjected to external impact, the rubber buffer pads 5 at its four outer corners absorb the impact energy through deformation, reducing the vibration transmitted to the screen assembly 3.

[0049] In the upper and lower part of the snap-fit ​​groove 12 on the front side of the protective side plate 8, push the external connecting slide plate 15 to slide along the front end of the inner cavity of the snap-fit ​​groove 12 to adjust its position to fit the external connecting parts or reserve operating space.

[0050] The corresponding structure enters the snap-fit ​​slot 12 through the insertion interface 13 for snap-fit ​​operation. The external sliding plate 15 drives the insertion post 14 to move synchronously in the snap-fit ​​slot 12 and compresses the spring 16. The elastic reset function ensures that the insertion post 14 always remains in the insertion state.

[0051] Align the semi-circular grooves 19 on the surface of the protective top plate 7, the protective bottom plate 9 and the side protrusions 22, so that two adjacent sets of semi-circular grooves 19 are combined to form a complete circular groove. Then, the annular clamping plate 20 is embedded into the inner cavity of the complete circular groove to fix the protective components.

[0052] The protective frame 1 is assembled from the split-design protective top plate 7, protective side plate 8 and protective bottom plate 9, which facilitates partial replacement and maintenance. Together with the rubber buffer pad 5, it resists external impact and vibration, and extends the service life of the screen assembly 3.

[0053] A sealing strip 4 is provided at the connection between the protective frame 1 and the screen assembly 3. When the dustproof flip cover 2 is closed, it is directly attached to the front of the screen assembly 3 to form a double sealing barrier, which effectively prevents liquid or dust from entering and is suitable for high dust or humid environments.

[0054] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
