Description

Technical Field

[0001] This application relates to the field of tablet computer testing technology, and more specifically, to a rotating mechanism testing device. Background Technology

[0002] As a smart terminal device integrating display and control functions, the rotating mechanism of a tablet remote control is a key motion component for achieving multi-angle adjustment of the screen or operating parts. This rotating mechanism typically consists of a fixed part and a relatively rotatable rotating part, achieving smooth and reliable reciprocating rotational motion through hinges, shafts, or other mechanical connections. To ensure that the product meets design life requirements before mass production, manufacturers must conduct aging tests (also known as life tests or durability tests) on the rotating mechanism to simulate tens of thousands or even hundreds of thousands of rotational movements that it might experience in actual use, thereby verifying its structural strength, friction and wear characteristics, and overall stability.

[0003] Currently, aging tests are typically conducted manually, where operators repeatedly rotate the mechanism to a specified angle and count the cycles. This method is not only extremely inefficient and labor-intensive, but also makes it difficult to ensure consistency and standardization of actions, easily introducing human error and affecting the accuracy and repeatability of test results. Furthermore, the long hours of repetitive labor result in significant workload, which is not conducive to large-scale batch testing. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] As a smart terminal device integrating display and control functions, the rotating mechanism of a tablet remote control is a key motion component for achieving multi-angle adjustment of the screen or operating parts. This rotating mechanism typically consists of a fixed part and a relatively rotatable rotating part, achieving smooth and reliable reciprocating rotational motion through hinges, shafts, or other mechanical connections. To ensure that the product meets design life requirements before mass production, manufacturers must conduct aging tests (also known as life tests or durability tests) on the rotating mechanism to simulate tens of thousands or even hundreds of thousands of rotational movements that it might experience in actual use, thereby verifying its structural strength, friction and wear characteristics, and overall stability.

[0024] Currently, aging tests are typically conducted manually, where operators repeatedly rotate the mechanism to a specified angle and count the cycles. This method is not only extremely inefficient and labor-intensive, but also makes it difficult to ensure consistency and standardization of actions, easily introducing human error and affecting the accuracy and repeatability of test results. Furthermore, the long hours of repetitive labor result in significant workload, which is not conducive to large-scale batch testing.

[0025] To solve the above technical problems, refer to Figure 1 As shown, this application provides a rotating mechanism testing device, including a first support base 100, a second support base 101, a swing mounting base 102, and a drive mechanism 103; the first support base 100 is connected to the fixed part 104 of the rotating mechanism, and the swing mounting base 102 is connected to the rotating part 105 of the rotating mechanism; a rotating shaft 106 parallel to and spaced from the rotation axis of the rotating mechanism is mounted on the second support base 101, and a swing rod 107 is provided on the rotating shaft 106; one end of the swing rod 107 is connected to the swing mounting base 102, and the other end is connected to the drive mechanism 103; the drive mechanism 103 drives the swing rod 107 to move around the rotating shaft 106, and drives the rotating part 105 of the rotating mechanism to reciprocate around the rotation axis through the swing mounting base 102.

[0026] It should be noted that the embodiments of this application achieve automated reciprocating drive of the rotating mechanism through a mechanical linkage structure. The device of the embodiments of this application includes a first support base 100, a second support base 101, a swing mounting base 102, and a drive mechanism 103: the first support base 100 fixes the stationary fixed part 104 of the rotating mechanism, and the swing mounting base 102 connects to its rotating part 105; the second support base 101 is provided with rotating shafts 106 arranged parallel to and at intervals with the rotation axis of the rotating mechanism, and a swing rod 107 is mounted on it, one end of the swing rod 107 is hinged to the swing mounting base 102, and the other end is connected to the drive mechanism 103.

[0027] It should be noted that, in the present application embodiment, when working, the drive mechanism 103 drives the rocker arm 107 to swing around the rotating shaft 106, and then the rocker mounting base 102 converts the swing motion into the reciprocating rotation motion of the rotating part 105 of the rotating mechanism around its own axis, thereby efficiently, stably and repeatably simulating the opening and closing action in actual use, and realizing automated aging test of the life and reliability of the rotating mechanism.

[0028] It should be noted that, by setting up a first support base 100, a second support base 101, a swing mounting base 102, and a drive mechanism 103, this application embodiment constructs a simple and highly adaptable automated testing device for rotating mechanisms. This application embodiment can accurately simulate the reciprocating motion of the rotating mechanism of a tablet remote control in actual use, effectively replacing manual operation and significantly improving testing efficiency and consistency. At the same time, this device avoids the problems of complex structure, high cost, and poor adaptability of general aging equipment, and has the advantages of convenient clamping, stable operation, and low maintenance cost. It can meet the needs of efficient and accurate verification of the durability and reliability of rotating mechanisms before mass production of large-scale products.

[0029] Reference Figure 2 , Figure 3 as well as Figure 4 As shown, in one optional implementation, the drive mechanism 103 includes a drive motor 108 and a crank connecting rod 109; the power output end of the drive motor 108 is connected to the crank connecting rod 109, and the crank connecting rod 109 drives the rocker arm 107 to swing back and forth around the rotating shaft 106.

[0030] In one optional embodiment of this application, the drive mechanism 103 specifically includes a drive motor 108 and a crank connecting rod 109, wherein the power output end of the drive motor 108 is connected to the crank connecting rod 109, and the continuous rotational motion of the motor is converted into the reciprocating swing of the rocker arm 107 around the rotating shaft 106 through the crank connecting rod 109.

[0031] The structure of this application embodiment is not only stable in transmission and precise in control, but also can effectively simulate the periodic opening and closing action of the rotating mechanism in actual use. Compared with manual operation or complex general equipment, this solution has a simple structure, reliable response, low operating noise, and is easy to adjust the angle and frequency, thereby improving the consistency, repeatability and automation level of aging test, significantly improving test efficiency and reducing test cost.

[0032] As an optional implementation, the rocker arm 107 is provided with a plurality of hinges arranged at intervals along the length of the rocker arm 107; the crank connecting rod 109 is connected to different hinges and can be used to adjust the angle of reciprocating swing of the rocker arm 107.

[0033] In one optional embodiment of this application, the rocker arm 107 is provided with a plurality of hinges arranged at intervals along its length. The crank connecting rod 109 can adjust the range of the rocker arm 107’s reciprocating swing around the pivot 106 by selectively connecting the hinges at different positions to change the lever arm length.

[0034] It should be noted that since the output stroke (i.e., push-pull displacement) of the crank-connecting rod 109 is fixed, according to the lever principle, when the connection point of the crank-connecting rod 109 is close to the rotation center (i.e., the shaft 106) of the rocker arm 107, the lever arm generated by the same stroke is shorter, resulting in a larger angular displacement of the rocker arm 107, i.e., a larger swing angle. Conversely, when the connection point is far from the rotation center, the lever arm becomes longer, the angular displacement caused by the same stroke decreases, and the swing angle becomes smaller accordingly. This structure allows for flexible adjustment of the test angle by simply changing the connection position, without modifying the drive mechanism 103 or the control system, effectively improving the device's adaptability to different specifications of rotating mechanisms and its testing flexibility.

[0035] This embodiment of the application provides multiple hinges spaced along the length of the rocker arm 107, allowing the crank connecting rod 109 to connect to different hinge points according to testing requirements. Utilizing the inverse relationship between the lever arm length and angular displacement under a fixed stroke, the reciprocating swing angle of the rotating mechanism can be flexibly adjusted: the closer the connection point is to the rotation center, the larger the swing angle; the farther away, the smaller the angle. This design eliminates the need to replace drive components or adjust motor parameters, quickly adapting to the testing requirements of different products for opening and closing angles. This significantly improves the versatility, ease of adjustment, and testing efficiency of the testing device, while ensuring repeatability accuracy, effectively meeting the aging test requirements of rotating mechanisms for various tablet remote controls.

[0036] Reference Figure 2 , Figure 3 as well as Figure 4As shown, in one optional embodiment, the end of the rocker arm 107 away from the drive mechanism 103 is provided with a sliding rod 110 parallel to the rotating shaft 106; the rocker mounting base 102 is provided with a strip hole 111, the extension direction of the strip hole 111 is perpendicular to the sliding rod 110, and the sliding rod 110 is inserted into the strip hole 111.

[0037] It should be noted that the end of the rocker arm 107 away from the drive mechanism 103 is provided with a sliding rod 110 parallel to the rotating shaft 106, and the rocker mounting base 102 is provided with a strip hole 111, the extension direction of which is perpendicular to the sliding rod 110, and the length of the strip hole 111 is greater than the diameter of the sliding rod 110, so that the sliding rod 110 can be movably inserted therein.

[0038] Since the swing mount 102 is used to clamp the rotating part 105 of the rotating mechanism, the rotating part 105 needs to rotate freely around its own axis during the test. If the swing mount 102 is rigidly connected to it, the reciprocating swing of the swing rod 107 may introduce additional constraints, causing friction or interference between the rotating part 105 and the mount. By setting a matching structure between the strip hole 111 and the sliding rod 110, the sliding rod 110 can slide freely in the strip hole 111 perpendicular to the rotation direction while transmitting the swing driving force, thereby achieving motion decoupling. This ensures that the swing mount 102 can effectively drive the rotating mechanism to reciprocate, while avoiding obstruction to the free rotation of the rotating part 105, preventing friction damage, and ensuring the smoothness of the test process and the authenticity of the movement of the tested mechanism.

[0039] As an optional implementation, the swing mounting base 102 is provided with a snap-fit ​​assembly for engaging the rotating part of the rotating mechanism.

[0040] It should be noted that the swing mounting base 102 in this embodiment of the application is provided with a snap-fit ​​assembly for quickly and securely snapping the rotating part 105 of the rotating mechanism. The snap-fit ​​assembly typically includes an elastic buckle, a positioning groove, or an adjustable clamping structure, which can adapt to rotating parts of different shapes and sizes, and achieve tool-free clamping and reliable fixation.

[0041] This embodiment of the application establishes a temporary but stable connection between the rotating part 105 of the rotating mechanism and the swing mounting base 102 through a mechanical snap-fit ​​method. When the drive mechanism 103 drives the swing arm 107 to reciprocate, it ensures that the rotating part 105 moves synchronously with the swing mounting base 102, thereby accurately simulating the opening and closing actions in actual use. Simultaneously, the snap-fit ​​structure avoids permanent or cumbersome fixing methods such as adhesives and screws, significantly improving assembly and disassembly efficiency and test turnaround speed. This design not only enhances the compatibility of the device with multiple product models but also improves the stability and repeatability of the testing process, effectively supporting the needs of efficient, batch aging verification.

[0042] It should be noted that the embodiments of this application can be flexibly adjusted or replaced according to the external dimensions, interface shape, or mounting hole positions of different models of rotating mechanisms, thereby achieving reliable clamping of products of various specifications. While ensuring synchronous movement between the rotating part 105 and the swing mounting base 102, stress concentration and assembly interference are avoided through non-rigid or adjustable connections, ensuring accurate transmission of test actions while preventing damage to the test piece. This design significantly improves the versatility and adaptability of the testing device, eliminating the need to develop separate fixtures for each model, and efficiently completing aging tests on rotating mechanisms of various types of tablet remote controls, greatly reducing testing costs.

[0043] Reference Figure 3 , Figure 4 As shown, in one optional implementation, the swing mounting base 102 is provided with a U-shaped groove 117 for mounting the rotating part 105, and the snap-fit ​​assembly includes at least two locking screws 118 inserted into one side of the U-shaped groove 117, with the ends of the locking screws 118 abutting against the rotating part 105.

[0044] It should be noted that the swing mounting base 102 is provided with a U-shaped groove 117 for mounting the rotating part 105 of the rotating mechanism. The snap-fit ​​assembly includes at least two locking screws 118 inserted into one side of the U-shaped groove 117. The ends of the locking screws 118 can be screwed in and abut against the outer surface of the rotating part 105.

[0045] It should be noted that after the rotating part 105 of the rotating mechanism is embedded into the U-shaped groove 117, tightening the locking screw 118 causes its end to press against the rotating part 105 from the side, achieving rapid positioning and reliable clamping. Since the U-shaped groove 117 provides initial limiting, and multiple locking screws 118 can apply clamping force from different positions, not only is the clamping stability enhanced, but it can also adapt to rotating parts of different thicknesses or dimensions. This structure is simple, easy to adjust, and provides firm clamping. It can be adapted to various product models without the need for special fixtures, effectively improving the versatility of the testing device, assembly and disassembly efficiency, and motion synchronization accuracy during testing.

[0046] As an optional implementation, the inner wall of the other side of the U-shaped groove 117 is provided with an elastic protective structure that contacts the rotating part 105.

[0047] It should be noted that the inner wall of the other side of the U-shaped groove 117 in this embodiment is provided with an elastic protective structure (such as a rubber pad, silicone layer, or spring pressure plate) that contacts the rotating part 105 of the rotating mechanism. This design, by introducing a flexible contact surface during clamping, can buffer pressure when the locking screw 118 applies clamping force, preventing direct contact between rigid metal parts and causing scratches, deformation, or stress concentration on the surface of the rotating part 105. Furthermore, the elastic structure can compensate for minor dimensional differences between different product models, improving clamping adaptability and stability. Combined with the mechanical positioning of the U-shaped groove 117 and the locking screw 118, this elastic protective structure effectively protects the appearance and functional integrity of the tested component while ensuring reliable transmission, balancing test accuracy and product safety. It is particularly suitable for aging tests of consumer electronics products with high surface quality requirements.

[0048] Reference Figure 2 As shown, as an optional implementation, a counting module is also included; the counting module includes a magnet 112 mounted on the crank connecting rod 109, and an induction counter 113 mounted on one side of the magnet 112; the induction counter 113 is used to sense the number of times the magnet 112 passes by.

[0049] It should be noted that the testing device in this embodiment further includes a counting module, which consists of a magnet 112 mounted on the crank connecting rod 109 and an inductive counter 113 fixed to one side of the movement trajectory of the magnet 112. Alternatively, a Hall sensor or a magnetic proximity switch may be used.

[0050] When the drive mechanism 103 drives the crank connecting rod 109 to reciprocate, the magnet 112 or magnetic proximity switch periodically passes through the induction counter 113 or Hall sensor. Each pass is recorded as a complete oscillation cycle, thus accurately counting the number of tests completed by the rotating mechanism. This counting method has a simple structure, reliable response, and strong anti-interference ability. It can achieve high-precision automatic counting without contact, effectively avoiding errors or omissions in manual counting. At the same time, combined with the control system, it can also realize functions such as life threshold setting, automatic shutdown, or data uploading, significantly improving the intelligence level and traceability of aging tests. It is suitable for standardized and efficient durability verification of different models of rotating mechanisms.

[0051] Reference Figure 2 As shown, as an optional implementation, a digital display screen 114 is also included. The digital display screen 114 is electrically connected to the induction counter 113 and is used to display the number of reciprocating movements of the rotating part 105.

[0052] It should be noted that the testing device is equipped with a digital display screen 114, which is electrically connected to the induction counter 113 and is used to display the number of reciprocating motions of the rotating part 105 of the rotating mechanism in real time.

[0053] It should be noted that each time the crank connecting rod 109 drives the magnet 112 past the induction counter 113, the induction counter 113 outputs a pulse signal. The control system counts this signal and synchronously updates the cumulative count on the digital display screen 114. This design achieves visualization of the testing process and intuitive data presentation, allowing operators to instantly grasp the current aging test progress without relying on external equipment or manual recording. Furthermore, combined with preset lifespan thresholds, it can assist in determining whether the test meets the standards, improving testing efficiency and accuracy. The overall structure is simple, low-cost, and highly reliable, significantly enhancing the device's human-machine interaction, automation level, and standardized testing capabilities applicable to multiple product models.

[0054] Reference Figure 1 , Figure 2 As shown, as an optional embodiment, it also includes a base 115 and a protective cover 116; the first support 100 and the second support 101 are both fixed on the base 115; the protective cover 116 is installed on the base 115 and covers the outside of the drive mechanism 103.

[0055] It should be noted that the testing device further includes a base 115 and a protective cover 116. The first support 100 and the second support 101 are both securely mounted on the base 115, providing rigid support and positioning reference for the entire testing mechanism, ensuring the relative position of each component is stable and the force is evenly distributed during movement. The protective cover 116 is fixed to the base 115 and covers the outside of the drive mechanism 103, isolating moving parts such as the drive motor 108 and the crank connecting rod 109 to prevent accidental contact by operators and to prevent dust and foreign objects from entering the transmission system, thus improving the reliability and service life of the equipment. This structure not only enhances the overall integration and mechanical stability of the device but also considers operational safety and ease of maintenance, making it suitable for long-term, continuous aging testing in factory environments.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
