Description

Technical Field

[0001] This invention relates to the field of folding test for foldable mobile phones, and specifically to a high and low temperature folding test device and test method for foldable mobile phones. Background Technology

[0002] The high and low temperature folding test equipment for foldable phones is a specialized testing device used to evaluate the mechanical reliability, optical performance, and material durability of foldable screen phones (such as flexible screens, protective films, hinges, and other key components) after repeated folding and unfolding operations in extreme high and low temperature cycling environments. This equipment belongs to the interdisciplinary field of electronic product reliability testing, environmental simulation testing, and precision mechanical automation technology. It is a key tool for ensuring the quality of related products in foldable phones, predicting their lifespan, and verifying design reliability.

[0003] In existing technologies, high and low temperature testing equipment for foldable phones typically consists of a high and low temperature environmental test chamber, a mechanical folding actuator placed inside the chamber, and a control system. Its basic working principle is as follows: the foldable phone to be tested is fixed to a test fixture (such as two clamping plates), which hold the two parts of the phone (usually the folding end). Then, a drive device such as a motor, crank connecting rod, or cylinder drives one clamping plate to reciprocate relative to the other, thereby simulating the opening and closing folding action of the phone. The test process is continuously repeated several times under a set temperature environment to assess its durability.

[0004] However, existing folding tests still have certain shortcomings. First, most existing devices use rigid clamps to directly clamp the phone body, concentrating the clamping force on the phone casing rather than the rotation center of its internal hinge. When the clamps are driven to swing, the swing trajectory is difficult to precisely align with the actual rotation center of the phone hinge, resulting in unexpected torsional loads and compressive stresses on the phone casing and hinge. This can easily lead to physical damage to the screen, frame, or hinge, turning the test itself into a source of damage and affecting the accuracy and validity of the test results.

[0005] Secondly, the opening and closing angle of the device lacks simulation of the real force state. The hinge system of foldable phones usually has a built-in torque structure that provides specific unfolding and folding forces. When the opening and closing angle is too large or too small, the external driving force will fight against the internal hinge force of the phone, resulting in impact or "hard squeezing", which deviates from the real use scenario and affects the actual test results.

[0006] Furthermore, due to the lack of a precise alignment feedback mechanism, deviations in phone installation lead to poor consistency in testing conditions, making test data from different batches or devices incomparable. Therefore, there is an urgent need for a high- and low-temperature folding test device and method that simulates manual opening and closing actions and coordinates with the flexible testing of mobile phones. Summary of the Invention

[0007] The purpose of this invention is to address the above-mentioned deficiencies by providing a high and low temperature folding test device and test method for foldable mobile phones, thereby solving the technical problem in the background art of how to improve the accuracy and effectiveness of folding tests in a simulated environment.

[0008] The objective of this invention is achieved through the following means:

[0009] A high and low temperature folding test device for foldable mobile phones includes a cabinet with a receiving cavity inside. The cabinet is used to regulate the temperature environment inside the receiving cavity. A rotating mechanism is provided inside the cabinet, and the rotating mechanism is connected to a rotatable central shaft. One end of the central shaft passes through the receiving cavity and is located on the inner side of the receiving cavity. A laser centering positioner coaxial with and opposite to the central shaft is provided on the inner side of the receiving cavity. A lifting platform is provided inside the receiving cavity, and an openable clamping mechanism is connected to the lifting platform. The clamping mechanism is configured to clamp and fix the first body end of the foldable mobile phone. A swing arm is detachably connected to the end of the central shaft near the receiving cavity. A flipping swing shaft extending towards the clamping mechanism is detachably connected to the side of the swing arm. A lifting ring block passes through the end of the flipping swing shaft near the clamping mechanism. The lifting ring block is configured to be bonded to the second body end of the foldable mobile phone, and a lifting ring hole for passing through the flipping swing shaft is provided on the lifting ring block. A buffer gap is left between the inner side of the lifting ring hole and the outer side of the flipping swing shaft.

[0010] When the first body of the mobile phone is clamped and fixed on the clamping mechanism, the second body of the mobile phone flips and folds with the first body. The hanging ring block is attached to the outer side of the second body. One end of the flipping swing shaft is inserted into the hanging ring hole. The rotating mechanism drives the central shaft to rotate the swing arm, so that the flipping swing shaft can move the hanging ring block to drive the second body to flip relative to the first body.

[0011] Furthermore, as described above, the rotating mechanism includes a drive motor, which is connected to the cabinet via a motor mount, and the output shaft of the drive motor is coaxially connected to one end of the central shaft via a coupling.

[0012] Furthermore, as described above, the laser centering positioner is detachably mounted inside the receiving cavity via a fixing seat.

[0013] The laser alignment positioner is detachably mounted inside the receiving cavity via a mounting bracket, providing a reliable feedback mechanism for precise alignment of the phone's hinge structure with the central axis. The detachable design facilitates maintenance, calibration, or replacement of the laser alignment positioner, ensuring the comparability and reliability of test data from different batches or devices.

[0014] Furthermore, as described above, the lifting platform is composed of a Z-axis scissor lift, and the side of the Z-axis scissor lift is connected to an adjusting screw for manually adjusting the lifting height.

[0015] The Z-axis scissor lift is used as the lifting platform and equipped with a manual adjustment screw, which realizes the smooth and precise lifting of the clamping mechanism and the mobile phone it holds in the vertical direction.

[0016] Further, as described above, the Z-axis scissor lift is connected to a worktable with several connection holes. The clamping mechanism includes a base plate, a first clamping block, a second clamping block, a positioning seat, and an adjustment assembly. The base plate is connected to the connection holes by bolts and can be adjusted and installed according to the mobile phone. The first clamping block and the second clamping block are positioned opposite each other at both ends of the base plate, and a clamping gap for holding the mobile phone is left between the first clamping block and the second clamping block. The positioning seat and the first clamping block are respectively installed at one end of the base plate. The adjustment assembly includes a handle bolt, a guide shaft, and a bushing. The bushing is installed on the positioning seat. One end of the guide shaft passes through the bushing and is connected to the second clamping block. The handle bolt passes through the positioning seat and is connected to the second clamping block, so that the rotation of the handle bolt can drive the second clamping block to move relative to the first clamping block.

[0017] The fixture mechanism is multi-point adjustable in its mounting position by connecting multiple holes on the base plate to the worktable via bolts, allowing for flexible adaptation to folding phones of different sizes and models. The fixture mechanism uses a handle bolt to drive the second clamping block to move smoothly along the guide shaft, thus achieving clamping of the first body end.

[0018] Furthermore, as described above, the inner sides of the first clamping block and the adjacent inner sides of the first clamping block are provided with steps for supporting the mobile phone, and the inner sides of the first clamping block and the adjacent inner sides of the first clamping block are connected with pads.

[0019] By setting steps and pads on the inner sides of the first and second clamping blocks, the phone is provided with support and contact. The steps can limit the movement of the phone's sides, while the pads (usually made of elastic materials such as silicone) can buffer the clamping force, increase the contact area, disperse pressure, and further protect the phone's casing from damage.

[0020] Further, as described above, the swing arm includes a first connecting part and a second connecting part. The first connecting part is connected to one end of the central shaft, and the second connecting part has a plurality of positioning holes. One end of the flipping swing shaft is detachably paired and connected to a positioning hole.

[0021] By creating multiple positioning holes on the second connecting part of the swing arm and detachably pairing the flip swing shaft with one of these positioning holes, the rotation radius of the flip swing shaft relative to the central axis can be changed. This allows the device to adaptively adjust according to the hinge torque characteristics and required flip lever arm of different folding phones. When driving the flip swing shaft to move the hanging ring block, a more suitable force application point can be selected, avoiding excessively large or small opening angles due to improper flip lever arm settings. This prevents external driving force from clashing and impacting the internal hinge force of the phone, making the testing process closer to the gentle flicking action applied by the hand in real-world usage scenarios, and significantly improving the actual testing results.

[0022] Furthermore, as described above, the lifting ring block includes an adhesive portion and a lifting ring portion. The back of the adhesive portion is configured for attaching a mobile phone. A lifting ring hole is formed on the lifting ring portion, and the inner diameter of the lifting ring hole is larger than the outer diameter of the flipping swing shaft.

[0023] The lifting ring is connected to the second body of the phone via an adhesive joint, achieving a non-destructive, flexible fixation method that avoids physical damage to the phone's appearance and structure caused by clamping. The inner diameter of the lifting ring hole is configured to be larger than the outer diameter of the flip pivot, forming a buffer gap between them, thus creating a non-rigid, movable coupling.

[0024] A high and low temperature folding test method for foldable mobile phones, comprising testing using high and low temperature folding test equipment, and the folding test method including:

[0025] Step S101: Apply a screen protector or flexible screen to the foldable phone;

[0026] Step S102: The foldable phone includes a first body end and a second body end. The first body end and the second body end are hinged together by a hinge structure. The first body end is placed within the clamping distance. The first clamping block and the second clamping block are adjusted to clamp the first body end. The height is adjusted by manually controlling the Z-axis scissor lift platform. The hinge structure is aligned with the central axis by a laser centering positioner. The second body end can be folded relative to the first body end.

[0027] Step S103: Attach the lifting ring block to the end of the second body. At the same time, match the lifting ring hole with the tilting shaft, and leave a buffer gap between the lifting ring hole and the tilting shaft.

[0028] Step S104: Adjust the temperature environment inside the housing cavity by using the heating or cooling module on the cabinet to simulate the flipping and folding test under high or low temperature conditions.

[0029] In step S105, the central shaft can be driven by the drive motor to rotate the swing arm forward or backward, so that the swing arm can move the hanging ring block by flipping the swing shaft, thereby causing the second body end to unfold or fold relative to the first body end. When flipped to the unfolded state, the first body end rotates to a preset position and automatically unfolds through the elasticity of the folding phone. When flipped to the folded state, the second body end rotates to a preset position and automatically folds and fits through the magnetic attraction of the folding phone.

[0030] Furthermore, in the above description, the temperature value in step S104 is -40°C to 60°C.

[0031] Furthermore, in the above description, the rotation angle of the swing arm in step S105 is -10° to 180°.

[0032] The beneficial effects of this invention are as follows: By setting a laser alignment positioner coaxial with the central axis inside the receiving cavity and combining it with an adjustable lifting platform, the rotation center of the phone hinge is precisely aligned with the rotation center of the device drive. By using a lifting ring block bonded to the second body end of the folding phone and driven by a flip-up pivot shaft passing through the lifting ring hole, and simultaneously setting a buffer gap between the inner side of the lifting ring hole and the outer side of the flip-up pivot shaft, a compliant, non-rigid drive connection is constructed. This ensures that the flip-up pivot shaft and the driven part of the phone are not rigidly connected, and the buffer gap provides a certain amount of flexibility. This, combined with the elastic unfolding or automatic magnetic folding of the folding phone hinge, effectively simulates the gentle force applied when manually opening and closing the phone. This adapts to the actual rotation of the phone hinge, avoiding unexpected torsional loads and compressive stresses on the phone screen, frame, or hinge caused by rigid clamping of the phone's opening and closing drive and mismatched trajectories. This improves the safety and accuracy of the test results, ensuring that the phone hinge can unfold or fold according to its own built-in torque structure, thereby improving the actual test effect.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0053] To make the technical problem to be solved, the technical solution and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0054] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0055] In this embodiment, refer to Figures 1-11 Specifically, the flip-up pivot 600 is connected to the central shaft 1 driven by the rotating mechanism via the pivot arm 400, forming a rotation drive structure. When the central shaft 1 rotates, the pivot arm 400 drives the flip-up pivot 600 to move along an arc-shaped trajectory. The flip-up pivot 600 is coaxially set with the hanging ring hole 503. When the preset toggle angle is 175 degrees, the flip-up pivot 600 can move the hanging ring block 500 through the buffer gap 504, causing the second body end 702 of the mobile phone to flip to the preset angle, and automatically unfolds through the hinge of the mobile phone, eliminating the control error of the rotation angle. When the preset toggle angle is 175 degrees, the flip-up pivot 600 drives the second body end 702 to flip to the preset angle through the hanging ring block 500, and automatically folds through the magnetic attraction of the mobile phone.

[0056] The setting of the hanging ring block 500 on the flipping pivot 600, through the existence of the buffer gap 504, makes the drive a "pushing" rather than a "forceful push". Its movement can better coordinate with the torque characteristics of the built-in hinge of the mobile phone, simulating the real opening and closing force state, avoiding the "hard squeezing" or impact between the external driving force and the internal hinge force, making the test closer to the actual use scenario, improving the effectiveness of the test and the real test results.

[0057] A high and low temperature folding test device for foldable mobile phones includes a cabinet 100 and a cabinet door. The cabinet 100 contains a receiving cavity 101, which is used to regulate the temperature environment within the receiving cavity 101. A rotating mechanism is installed inside the cabinet 100, connected to a rotatable central shaft 1. One end of the central shaft 1 passes through the receiving cavity 101 and is located on one inner side of the receiving cavity 101. A laser alignment positioner 2, coaxial with and opposite to the central shaft 1, is installed on the inner side of the receiving cavity 101. A lifting platform 200 is installed inside the receiving cavity 101, and a clamping machine capable of opening and closing is connected to the lifting platform 200. The clamping mechanism 300 is configured to clamp and fix the first body end 701 of the folding mobile phone 700. The end of the central shaft 1 near the receiving cavity 101 is connected to a swing arm 400. The side of the swing arm 400 is connected to a flipping swing shaft 600 extending toward the clamping mechanism 300. The end of the flipping swing shaft 600 near the clamping mechanism 300 is provided with a lifting ring block 500. The lifting ring block 500 is configured to be bonded to the second body end 702 of the folding mobile phone 700. The lifting ring block 500 is provided with a lifting ring hole 503 for the flipping swing shaft 600 to pass through. A buffer gap 504 is left between the inner side of the lifting ring hole 503 and the outer side of the flipping swing shaft 600.

[0058] When the first body end 701 of the mobile phone is clamped and fixed on the clamping mechanism 300, the second body end 702 of the mobile phone flips and folds with the first body end 701. The hanging ring block 500 is attached to the outer side of the second body end 702. One end of the flipping swing shaft 600 passes through the hanging ring hole 503. The rotating mechanism drives the central shaft 1 to drive the swing arm 400 to rotate, so that the flipping swing shaft 600 can move the hanging ring block 500 to drive the second body end 702 to flip relative to the first body end 701.

[0059] Specifically, in this embodiment, the rotating mechanism includes a drive motor 3, which is connected to the cabinet 100 via a motor base 4, and the output shaft of the drive motor 3 is coaxially connected to one end of the central shaft 1 via a coupling 5.

[0060] Specifically, in this embodiment, the drive motor 3 is composed of a servo motor, and a controller is provided on the cabinet 100 to control the rotation speed and angle of the servo motor.

[0061] Specifically, the laser centering positioner 2 is detachably mounted inside the receiving cavity 101 via a fixing seat 6.

[0062] The laser alignment positioner 2 is detachably mounted inside the receiving cavity 101 via the fixing base 6, providing a reliable feedback mechanism for the precise alignment of the mobile phone hinge structure with the central axis 1. The detachable design facilitates the maintenance, calibration, or replacement of the laser alignment positioner 2, ensuring the comparability and reliability of test data from different batches or different devices.

[0063] When installing a mobile phone, the locator can provide a visual reference point or line coaxial with the central axis 1. The operator can use this reference to precisely adjust the installation position of the mobile phone to ensure that its hinge center is highly aligned with the rotation center of the equipment, thus solving the problem of poor consistency of test conditions caused by installation deviation.

[0064] In some embodiments, the laser centering positioner 2 uses a red laser positioner to perform positioning by a single point, a line, or a cross.

[0065] In some embodiments, the lifting platform 200 is composed of a Z-axis scissor lift, and the side of the Z-axis scissor lift is connected to an adjusting screw 202 for manually adjusting the lifting height.

[0066] A Z-axis scissor lift is used as the lifting platform 200, and a manual adjustment screw 202 is configured to achieve stable and precise lifting of the clamping mechanism 300 and the mobile phone it holds in the vertical direction.

[0067] When aligning the hinge with the laser alignment positioner 2, the operator can finely adjust the height of the phone by rotating the adjusting screw 202, so that the center line of the phone hinge and the axis of the central axis 1 can be precisely intersected in space.

[0068] It is worth further explaining that the lifting platform 200 and clamping mechanism 300 used in this embodiment are conventional technical components required to achieve the corresponding lifting height and clamping adjustment purposes. Their specific structure, driving method and control principle are conventional technical means in this field. Any existing device that can achieve the lifting and clamping action functions described in this embodiment can be equivalently replaced and applied to this technical solution.

[0069] A worktable 201 is connected to the Z-axis scissor lift platform. The worktable 201 has several connection holes 203. The clamping mechanism 300 includes a base plate 301, a first clamping block 302, a second clamping block 303, a positioning seat 304, and an adjustment assembly. The base plate 301 is bolted to the connection holes 203 and can be adjusted for installation according to the mobile phone. The first clamping block 302 and the second clamping block 303 are positioned opposite each other at both ends of the base plate 301, with a space between them for... The clamping distance for holding the mobile phone is determined by the positioning seat 304 and the first clamping block 302, which are respectively installed at one end of the base plate 301. The adjustment assembly includes a handle bolt 305, a guide shaft 306, and a bushing 307. The bushing 307 is installed on the positioning seat 304. One end of the guide shaft 306 passes through the bushing 307 and is connected to the second clamping block 303. The handle bolt 305 passes through the positioning seat 304 and is connected to the second clamping block 303, so that the rotation of the handle bolt 305 can drive the second clamping block 303 to move relative to the first clamping block 302.

[0070] By connecting the base plate 301 to the worktable 201 with multiple connecting holes 203 and bolts, the installation position of the clamping mechanism 300 is adjustable at multiple points, which can flexibly adapt to different sizes and models of folding mobile phones 700. The clamping mechanism 300 adopts an adjustment method in which the second clamping block 303 is driven by the handle bolt 305 to move smoothly along the guide shaft 306, thereby achieving the clamping of the first body end 701.

[0071] The first clamping block 302 and the adjacent inner sides of the first clamping block 302 are provided with steps for supporting the mobile phone, and the adjacent inner sides of the first clamping block 302 and the first clamping block 302 are connected with pads 308.

[0072] By providing steps and pads 308 on the inner sides of the first and second clamping blocks 303, the phone is supported and contacted. The steps can limit the movement of the phone's sides, while the pads 308 (usually made of elastic materials such as silicone) can buffer the clamping force, increase the contact area, disperse pressure, and further protect the phone's casing from damage.

[0073] The swing arm 400 includes a first connecting part 401 and a second connecting part 402. The first connecting part 401 is connected to one end of the central shaft 1, and the second connecting part 402 is provided with a plurality of positioning holes 403. One end of the flipping swing shaft 600 is detachably paired with a positioning hole 403.

[0074] By opening multiple positioning holes 403 on the second connecting part 402 of the swing arm 400 and detachably pairing the flipping swing shaft 600 with one of the positioning holes 403, the rotation radius of the flipping swing shaft 600 relative to the central axis 1 can be changed. This allows the device to adaptively adjust according to the hinge torque characteristics and required flipping lever arm of different folding phones 700. When driving the flipping swing shaft 600 to move the hanging ring block 500, a more suitable force application point can be selected, avoiding excessively large or small opening and closing angles due to improper flipping lever arm settings. This prevents external driving force from clashing and impacting the internal hinge force of the phone, making the testing process closer to the gentle flicking action applied by the hand in real-world usage scenarios, and significantly improving the actual testing effect.

[0075] In some embodiments, the swing arm 400 and the tilting pivot 600 may be an integrally formed structure.

[0076] Specifically, in this embodiment, the swing arm 400 has an "L" shaped structure.

[0077] The lifting ring block 500 includes an adhesive part 501 and a lifting ring part 502. The back side of the adhesive part 501 is configured for attaching a mobile phone. The lifting ring hole 503 is formed on the lifting ring part 502. The inner diameter of the lifting ring hole 503 is larger than the outer diameter of the flip swing shaft 600.

[0078] The lifting ring block 500 is connected to the second body end 702 of the mobile phone via the adhesive part 501, achieving a non-destructive flexible fixation method and avoiding physical damage to the appearance and structure of the mobile phone caused by clamping. The inner diameter of the lifting ring hole 503 is configured to be larger than the outer diameter of the flip pivot 600, forming a buffer gap 504 between the two, which constitutes a non-rigid movable coupling.

[0079] When there is a slight deviation between the rotation trajectory of the flip pivot 600 and the actual movement trajectory of the phone hinge, the buffer gap 504 can effectively absorb and resolve the resulting radial displacement and stress, ensuring that the flip pivot 600 only provides the lifting ring block 500 with the tug force along the swing direction, and will not transmit the unexpected torsional load or compressive force to the hinge through the second body end 702, thereby cooperating flexibly with the phone and solving the problem of device damage to the phone due to alignment error.

[0080] A high and low temperature folding test method for foldable mobile phones, comprising testing using high and low temperature folding test equipment, and the folding test method including:

[0081] Step S101: Apply a screen protector (e.g., UTG glass film, flexible film) to the folding phone 700;

[0082] Step S102: The foldable phone 700 includes a first body end 701 and a second body end 702. The first body end 701 and the second body end 702 are hinged together by a hinge structure. The first body end 701 is placed within the clamping distance. The first body end 701 is clamped by adjusting the first clamping block 302 and the second clamping block 303. The height is adjusted by manually controlling the Z-axis scissor lift platform. The hinge structure is aligned with the central axis 1 by the laser centering positioner 2. The second body end 702 can be folded relative to the first body end 701.

[0083] In step S103, the lifting ring block 500 is glued to the second body end 702. At the same time, the lifting ring hole 503 is paired with the flipping swing shaft 600, and a buffer gap 504 is left between the lifting ring hole 503 and the flipping swing shaft 600.

[0084] Step S104: Adjust the temperature environment inside the receiving cavity 101 by using the heating or cooling module on the cabinet 100 to simulate the flipping and folding test at high or low temperatures (such as 45°C).

[0085] In step S105, the drive motor 3 can drive the central shaft 1 to rotate the swing arm 400 forward or backward (e.g., 180 degrees), so that the swing arm 400 can move the hanging ring block 500 through the flipping swing shaft 600, thereby causing the second body end 702 to unfold or fold relative to the first body end 701. When flipped to the unfolded state, the first body end 701 rotates to a preset position and automatically unfolds through the elasticity of the folding phone 700. When flipped to the folded state, the second body end 702 rotates to a preset position and automatically folds and fits through the magnetic attraction of the folding phone 700.

[0086] In this embodiment, a lifting ring block 500 is bonded to the second body end 702 of the folding phone 700 and driven by a flip-up pivot 600 passing through the lifting ring hole 503. A buffer gap 504 is provided between the inner side of the lifting ring hole 503 and the outer side of the flip-up pivot 600, creating a compliant, non-rigid driving connection. This ensures that the flip-up pivot 600 and the driven part of the phone are not rigidly connected. The buffer gap 504 provides a certain amount of flexibility, thus simulating the gentle force applied when manually opening and closing the phone, adapting to the actual rotation of the phone hinge, improving the safety and accuracy of the test results, and ensuring that the phone hinge can unfold or fold according to the trajectory of its built-in torque structure, thereby improving the actual test effect.

[0087] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
