Description

Technical Field

[0001] The present invention relates to the field of mechanical structure and detection technology, and in particular to a flip cover installation structure and a detection system thereof. Background Art

[0002] In devices like printers, the flip cover is typically connected to the rear end of the upper cover. The flap legs rotate by inserting into the rear end of the upper cover through the rotation holes on the flap legs. A rubber roller is installed at the front end of the flap, which snaps into the main body of the device. However, the compact design of home or portable devices on the market compresses the internal structure, making it difficult to achieve its functional characteristics. Furthermore, the flap legs are relatively flexible, so when the flap is closed, the front end will swing left and right, preventing the rubber roller from properly snapping into the main body, affecting the normal operation of the device. Furthermore, the flip cover mounting structure is widely used in various devices, and its performance directly affects the user experience and service life of the device. During the production process of the flip cover mounting structure, the dimensional accuracy, assembly precision, and connection reliability of components such as the rotating shaft structure, detachable bushing, removable rubber roller structure, and elastic arm buckle are crucial. However, existing inspection methods are relatively limited and cannot comprehensively and accurately inspect the flip cover mounting structure, making it difficult to effectively ensure product quality. This can lead to problems such as poor flap rotation and loose rubber rollers during use, affecting the normal operation of the device.

[0003] Therefore, the existing fields of mechanical structures and detection technology need to be further improved. Summary of the Invention

[0004] The purpose of the present invention is to provide a flip cover installation structure and its detection system, to provide an installation and fixing structure that can enable the flip cover to be flipped over in a small space and accurately snapped into the movement main body, and to solve the problem that existing detection means are unable to perform comprehensive and accurate detection of the flip cover installation structure, to achieve effective detection of key indicators such as dimensional accuracy, fitting accuracy, locking performance and durability of each component of the flip cover installation structure, and to improve product quality and reliability.

[0005] In order to achieve the above object, the present invention adopts the following scheme: a flip cover mounting structure, comprising a base, an upper cover mounted on the base, a flip cover mounted on the upper cover, and a movement body disposed in the upper cover, wherein the flip cover is provided with a rotating shaft structure;

[0006] A split shaft sleeve for wrapping the rotating shaft structure is provided between the upper cover and the base;

[0007] A detachable rubber roller structure is provided on the flip cover;

[0008] Elastic arm buckles are provided on both sides of the movement body for locking the detachable rubber roller structure when the flip cover is closed.

[0009] Furthermore, the rotating shaft structure includes two flip cover protrusions spaced apart at the rear of the flip cover, and a rotating shaft is provided on each side wall of the flip cover protrusion.

[0010] Furthermore, the split shaft sleeve includes two slots spaced apart at the rear of the upper cover, wherein an upper semicircular arc groove is provided in the slot;

[0011] The tail of the base is provided with two upper extension ribs for correspondingly inserting into the slots, and the upper ends of the upper extension ribs are provided with lower semicircular arc grooves.

[0012] Furthermore, the upper semicircular arc groove and the lower semicircular arc groove are respectively wrapped around the upper and lower surfaces of the rotating shaft to form a complete shaft sleeve.

[0013] Furthermore, the detachable rubber roller structure includes two C-shaped positioning grooves spaced apart at the front end of the flip cover, and also includes a rubber roller body, with roller shafts provided at both ends of the rubber roller body, and the roller shafts are clamped on the C-shaped positioning groove on the corresponding side.

[0014] Furthermore, a guiding slope is provided at the bottom of the C-shaped positioning groove.

[0015] Furthermore, the elastic arm buckle includes a U-shaped groove provided on both sides of the movement body for installing the roller shaft, and the inner wall of the U-shaped groove is provided with an elastic buckle for locking the roller shaft.

[0016] A structural detection system includes: a frame body for fixing a base and upper cover assembly on which a flip-cover mounting structure is placed;

[0017] The optical measurement assembly, mounted on the main frame, includes a high-precision laser displacement sensor and a visual camera. The laser displacement sensor measures the diameter of the rotating shaft and the radius of the upper and lower semicircular arc grooves of the split sleeve. The visual camera detects the spacing between the flap protrusions and the clearance between the slot and the upper extension rib, analyzing the clearance deviation using an image processing algorithm.

[0018] The data acquisition and analysis unit is electrically connected to the optical measurement component and is used to collect measurement data and perform real-time analysis to determine whether the dimensional accuracy and fitting accuracy of the shaft structure and the split sleeve meet the design requirements, and generate a test report.

[0019] Furthermore, it also includes: a mounting platform for stably mounting the upper cover, the flip cover and the movement body;

[0020] The force loading and measurement module is installed on the mounting platform and consists of an electric push rod and a pressure sensor. The electric push rod is used to apply axial thrust to the rubber roller body of the detachable rubber roller structure. The pressure sensor measures the thrust value when the elastic buckle of the elastic arm buckle begins to release the roller shaft in real time.

[0021] The position detection component uses a linear displacement sensor installed at the joint between the flap and the rubber roller body to detect the installation position deviation of the rubber roller body in the C-shaped positioning groove;

[0023] Furthermore, it also includes: a main frame for supporting and fixing the entire detection device;

[0024] The flip cover drive mechanism is installed on the main frame and consists of a motor, a reducer and a crank connecting rod structure. The motor drives the crank connecting rod through the reducer to drive the flip cover to open and close;

[0025] The monitoring system includes multiple sensors, including an accelerometer mounted on the flip cover to monitor acceleration changes during opening and closing to determine whether there is abnormal vibration. Strain gauges are attached to key locations such as the split shaft sleeve and elastic arm buckle to monitor stress changes in components during long-term use. A counter is used to record the number of times the flip cover is opened and closed.

[0026] The data processing and alarm unit is electrically connected to the monitoring system and performs real-time analysis and processing on the sensor data. When it detects that the stress of a component exceeds the design threshold, the acceleration is abnormal, or the number of opening and closing times reaches the preset durability number, it issues an alarm signal and generates a durability test report to analyze the wear and fatigue of each component.

[0027] In summary, the present invention has the following beneficial effects compared to the prior art:

[0028] This invention addresses shortcomings in existing mechanical structures and testing technologies. Through its structural arrangement, it offers the following advantages: Through the coordination of the rotating shaft structure and the split shaft sleeve, stable flipping of the flip cover is achieved within a small space. The split shaft sleeve, formed by combining the structures on the upper cover and the base, forms a complete shaft sleeve that effectively limits and supports the rotating shaft, resolving the prior art issue of the flip cover's soft legs causing the front end to sway and deflect when the cover is closed. The design of the detachable rubber roller structure and the elastic arm buckle ensures that the rubber roller can be accurately snapped into the main body of the movement. The guiding bevel at the bottom of the C-shaped positioning groove guides the rubber roller smoothly into position when the flip cover is closed, while the elastic buckle of the elastic arm buckle ensures that the rubber roller is securely installed, improving the stability and reliability of the device. The structural inspection system comprehensively tests various performance indicators of the flip cover installation structure, including dimensional accuracy, fit accuracy, locking force, installation position deviation, and durability, thereby ensuring product quality and performance.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figures 1-11 The present invention provides a flip cover installation structure, comprising a base 1, an upper cover 2 installed on the base 1, a flip cover 3 installed on the upper cover 2, and a movement body 4 arranged in the upper cover 2, wherein the flip cover 3 is provided with a rotating shaft structure 5;

[0042] A split shaft sleeve 6 for wrapping the rotating shaft structure 5 is provided between the upper cover 2 and the base 1;

[0043] A detachable rubber roller structure 7 is provided on the flip cover 3;

[0044] Elastic arm buckles 8 are provided on both sides of the movement body 4 for locking the detachable rubber roller structure 7 when the flip cover 3 is closed;

[0045] The rotating shaft structure 5 serves as the rotation support core of the flip cover 3 and provides an axis for the flipping movement of the flip cover.

[0046] The split shaft sleeve 6 is composed of the structure on the upper cover 2 and the base 1. When the two are assembled, the upper semicircular groove 602 and the lower semicircular groove 604 wrap around the rotating shaft 502 to form a complete shaft sleeve. This not only limits the radial displacement of the rotating shaft 502 during the flipping process, but also provides it with a stable rotation track, thereby solving the problem of insufficient installation space for a traditional single shaft sleeve in a small space.

[0047] The detachable rubber roller structure 7 realizes the detachable connection between the rubber roller and the flip cover 3, which facilitates the installation, replacement and maintenance of the rubber roller.

[0048] When the flip cover 3 is closed, the elastic arm buckle 802 engages with the roller shaft 703 to firmly lock the rubber roller on the movement body 4, ensuring that the rubber roller will not move during the operation of the device and ensuring the normal operation of the device.

[0049] The hinge structure 5 of the present invention includes two flap projections 501 spaced apart at the rear of the flip cover 3, each with a hinge 502 disposed on either side of the flap projections 501. The two flap projections 501 spaced apart at the rear of the flip cover 3 form a stable support structure, increasing the overall strength and stability of the hinge structure 5 and preventing the shaking that could occur when the flip cover is flipped due to a single projection. The hinges 502 disposed on either side of each flap projection 501 provide two symmetrical rotational pivots for the flip cover 3, ensuring uniform force distribution during flipping, enabling a smoother flipping motion and effectively resolving the problem of front-end swaying and offsetting when closing the cover due to the flap's weak legs in the prior art. A slot 601 at the rear of the upper cover 2 accommodates the flap projections 501, with an upper semicircular arc-shaped slot 602 disposed within the slot 601, conforming to the upper surface of the hinge 502.

[0050] The upper extension rib 603 at the rear of the base 1 is designed to be inserted into the slot 601 of the upper cover 2 , and the lower semicircular arc groove 604 at the upper end fits with the lower surface of the rotating shaft 502 .

[0051] When base 1 and cover 2 are assembled, upper extension rib 603 inserts into slot 601, and upper and lower semicircular grooves 602 and 604 together enclose shaft 502, forming a complete sleeve. This split design eliminates the need for additional space for a separate sleeve in a small space. Instead, the combined structure of the cover and base fulfills the sleeve's function, significantly saving space while ensuring effective positioning and support for shaft 502.

[0052] The split shaft sleeve 6 of the present invention includes two slots 601 spaced apart and arranged at the rear of the upper cover 2 , and an upper semicircular arc groove 602 is arranged in the slots 601 ;

[0053] The tail of the base 1 is provided with two upper extension ribs 603 for correspondingly inserting into the slot 601, and the upper end of the upper extension rib 603 is provided with a lower semicircular groove 604; the upper semicircular groove 602 is wrapped around the upper surface of the rotating shaft 502, limiting the upward displacement of the rotating shaft 502.

[0054] The lower semicircular arc groove 604 wraps around the lower surface of the rotating shaft 502 to limit the downward displacement of the rotating shaft 502 .

[0055] The two functions together form an all-round radial constraint on the rotating shaft 502, so that the rotating shaft 502 can only rotate within the sleeve without any up and down shaking or deviation. This ensures the stability and accuracy of the flip cover 3 during the flipping process, allowing the flip cover to flip along the predetermined trajectory, thereby ensuring that the rubber roller can be accurately engaged with the movement body 4.

[0056] The upper semicircular arc groove 602 and the lower semicircular arc groove 604 of the present invention are respectively wrapped around the upper and lower surfaces of the rotating shaft 502 to form a complete shaft sleeve.

[0057] The detachable rubber roller structure 7 described in the present invention includes two C-shaped positioning grooves 701 arranged at intervals at the front end of the flip cover 3, and also includes a rubber roller body 702. A roller shaft 703 is provided at each end of the rubber roller body 702, and the roller shaft 703 is clamped on the C-shaped positioning groove 701 on the corresponding side; the two C-shaped positioning grooves 701 are arranged at intervals at the front end of the flip cover 3, providing an installation position for the rubber roller body 702.

[0058] The roller shafts 703 at both ends of the rubber roller body 702 are designed to be able to be snapped into the C-shaped positioning groove 701. This C-shaped opening design allows the roller shaft 703 to be easily inserted and removed, realizing a detachable connection between the rubber roller body 702 and the flip cover 3, which is convenient for replacement and maintenance of the rubber roller.

[0059] When the roller shaft 703 is inserted into the C-shaped positioning groove 701, the two side walls of the C-shaped positioning groove 701 form lateral constraints on the roller shaft 703, preventing the rubber roller body 702 from shifting in the horizontal direction, thereby ensuring the stability of the rubber roller during operation.

[0060] The bottom of the C-shaped positioning groove 701 of the present invention is provided with a guiding inclined surface.

[0061] The elastic arm buckle 8 of the present invention includes a U-shaped groove 801 provided on both sides of the movement body 4 for installing the roller shaft 703, and the inner wall of the U-shaped groove 801 is provided with an elastic buckle 802 for locking the roller shaft 703; the U-shaped groove 801 on both sides of the movement body 4 provides an installation position for the roller shaft 703, and when the flip cover 3 is closed, the roller shaft 703 enters the U-shaped groove 801.

[0062] The elastic buckle 802 on the inner wall of the U-shaped groove 801 has a certain degree of elasticity. When the roller 703 enters the U-shaped groove 801, the elastic buckle 802 will be elastically deformed and then clamp the roller 703, thereby firmly locking the rubber roller on the movement body 4 to prevent the rubber roller from loosening or displacement during operation of the equipment.

[0063] When the rubber roller needs to be disassembled, a certain external force is applied to the rubber roller to elastically deform the elastic buckle 802, thereby loosening the roller shaft 703 and realizing the disassembly of the rubber roller. This design not only ensures the installation firmness of the rubber roller, but also facilitates the disassembly and maintenance of the rubber roller.

[0064] A structural detection system includes: a frame body for fixing a base 1 and an upper cover 2 combination of a flip-up mounting structure;

[0065] The optical measurement assembly, mounted on the main frame, includes a high-precision laser displacement sensor and a visual camera. The laser displacement sensor is used to measure the diameter of the rotating shaft 502 and the radius of the upper semicircular groove 602 and the lower semicircular groove 604 of the split shaft sleeve 6. The visual camera is used to detect the spacing between the flip cover protrusion 501 and the clearance between the slot 601 and the upper extension rib 603, and analyze the clearance deviation using an image processing algorithm.

[0066] The data acquisition and analysis unit is electrically connected to the optical measurement component and is used to collect measurement data and perform real-time analysis to determine whether the dimensional accuracy and fit accuracy of the shaft structure 5 and the split shaft sleeve 6 meet the design requirements, and generate a test report;

[0067] The main frame provides a stable support platform for testing, ensuring that the flap installation structure will not shake during the testing process, thereby ensuring the accuracy of the test data.

[0068] The high-precision laser displacement sensor in the optical measurement component accurately measures the diameter of the rotating shaft 502 and the radii of the upper semicircular groove 602 and the lower semicircular groove 604 of the split sleeve 6 by emitting laser and measuring the reflection time or phase difference of the laser; the visual camera captures images and uses image processing algorithms to detect and analyze the spacing distance of the flip cover protrusion 501 and the fitting clearance between the slot 601 and the upper extension rib 603, thereby obtaining the dimensional accuracy and fitting accuracy information of these key parts.

[0069] The data acquisition and analysis unit collects and analyzes the data obtained by the optical measurement component in real time, compares it with the standard values ​​required by the design, determines whether the dimensional accuracy and fitting accuracy of the shaft structure 5 and the split sleeve 6 meet the requirements, and generates a test report to provide a basis for product quality assessment.

[0070] The present invention also includes: a mounting platform for stably mounting the upper cover 2, the flip cover 3 and the movement body 4;

[0071] The force loading and measurement module is installed on the mounting platform and consists of an electric push rod and a pressure sensor. The electric push rod is used to apply axial thrust to the rubber roller body 702 of the detachable rubber roller structure 7. The pressure sensor measures the thrust value when the elastic buckle 802 of the elastic arm buckle 8 begins to release the roller shaft 703 in real time.

[0072] The position detection component, which uses a linear displacement sensor, is installed at the joint between the flip cover 3 and the rubber roller body 702 to detect the installation position deviation of the rubber roller body 702 in the C-shaped positioning groove 701;

[0073] The control and display unit is electrically connected to the force loading and measurement module and the position detection component, and is used to control the thrust loading speed of the electric linear actuator, display the thrust value and the rubber roller installation position deviation data in real time, and judge whether the rubber roller locking force and positioning are qualified according to the preset standards;

[0074] The mounting platform is used to stably mount the upper cover 2, the flip cover 3 and the movement body 4, providing a stable working platform for force loading, measurement and position detection.

[0075] The electric push rod in the force loading and measurement module applies axial thrust to the rubber roller body 702 of the removable rubber roller structure 7 at a set speed. The pressure sensor measures the thrust in real time when the elastic buckle 802 of the elastic arm buckle 8 begins to release the roller shaft 703. This thrust value is the locking force of the rubber roller. By measuring the locking force, it can be determined whether the locking performance of the elastic arm buckle 8 meets the requirements. The bottom of the C-shaped positioning groove 701 is beveled to prevent the flip cover from twisting left and right when closing, which could collide with the U-shaped groove 801 of the movement, and the bevel serves as a guide.

[0076] The position detection component uses a linear displacement sensor, which is installed at the joint between the flip cover 3 and the rubber roller body 702 to detect the installation position deviation of the rubber roller body 702 in the C-shaped positioning groove 701 in real time, thereby determining whether the installation position of the rubber roller is accurate.

[0077] The control and display unit controls the thrust loading speed of the electric linear actuator, displays the thrust value and rubber roller installation position deviation data in real time, and judges whether the rubber roller locking force and positioning are qualified according to preset standards, providing an important reference for product quality control.

[0079] The flip cover drive mechanism is installed on the main frame and consists of a motor, a reducer and a crank connecting rod structure. The motor drives the crank connecting rod through the reducer to drive the flip cover 3 to open and close;

[0080] The monitoring system includes multiple sensors, including an acceleration sensor mounted on the flip cover 3 to monitor acceleration changes during the opening and closing process of the flip cover and determine whether there is abnormal vibration; strain gauges are attached to key locations such as the split shaft sleeve 6 and the elastic arm buckle 8 to monitor stress changes in components during long-term use; and a counter is used to record the number of times the flip cover is opened and closed.

[0081] The data processing and alarm unit is electrically connected to the monitoring system and performs real-time analysis and processing on the sensor data. When it detects that the stress of a component exceeds the design threshold, the acceleration is abnormal, or the number of opening and closing times reaches the preset durability number, it issues an alarm signal and generates a durability test report to analyze the wear and fatigue of each component. The main frame is used to support and fix the entire testing device to ensure the stability of each component during the testing process.

[0082] The flip cover drive mechanism consists of a motor, a reducer and a crank-connecting rod structure. The motor drives the crank-connecting rod through the reducer to drive the flip cover 3 to open and close, simulating the opening and closing action of the flip cover during actual use, thereby conducting a durability test on the flip cover installation structure.

[0083] The acceleration sensor in the monitoring system is installed on the flip cover 3 to monitor the acceleration changes in real time during the opening and closing process of the flip cover. By analyzing the abnormal acceleration, it is determined whether there is abnormal vibration, thereby evaluating the stability of the flip cover installation structure; strain gauges are pasted on key parts such as the split shaft sleeve 6 and the elastic arm buckle 8 to monitor the stress changes of these components during long-term use and understand the stress conditions and fatigue levels of the components; the counter is used to record the number of times the flip cover is opened and closed in order to determine the service life of the product.

[0084] The data processing and alarm unit is electrically connected to the monitoring system to perform real-time analysis and processing of sensor data.
