Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, specifically, it relates to an automated testing device based on a decoupling system. Background Technology

[0002] With the rapid development of communication technology, smartphones, as mobile terminals integrating communication, information interaction, and entertainment functions, have become an indispensable core tool in modern people's daily lives and work. However, a prominent pain point in current smartphones is their insufficient drop resistance. Because smartphone screens are mostly made of glass to ensure light transmission and scratch resistance, this material is inherently brittle, making the phone prone to screen breakage and internal structural damage when dropped or impacted. Therefore, accurately testing the impact resistance of the screen and the entire internal structure during the mobile phone manufacturing process, and optimizing production processes and structural designs based on the test results, has become a key step for manufacturers to improve product quality and enhance market competitiveness.

[0003] Existing technologies already include mobile phone impact resistance testing equipment, such as Chinese utility model patent CN207019861U, which discloses a mobile phone impact resistance testing machine. This patent uses an electromagnet inside the testing probe to attract the probe, releasing it when testing the impact resistance of the phone panel, and utilizing the probe's own gravity to complete the impact test. Simultaneously, the testing head of the probe can provide feedback on the test data. The overall structure is relatively simple, the testing cost is low, and it can perform multiple repeated tests. However, this solution has significant limitations: because the impact height of the testing probe remains constant during the test, and the impact force on the phone is directly related to the impact height, a fixed-height impact cannot simulate the force differences under different drop scenarios. This makes it difficult to comprehensively reflect the phone's impact resistance performance under different impact intensities, thus affecting the accuracy and reference value of the test results and failing to meet manufacturers' needs for refined evaluation of product impact resistance.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automated testing device for a decoupling system, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An automated testing device for a decoupling system includes:

[0008] Test fixture;

[0009] Unhooking device;

[0010] The traction device is installed on the top of the test frame, and the traction end of the traction device is fixedly connected to the unhooking device.

[0011] The impact device is slidably fitted inside the test frame and cooperates with the unhooking device.

[0012] Protective devices, including retractable baffles and restraint components;

[0013] The constraint assembly includes a housing, which is installed on one side of the test frame. A stop bar is slidably fitted inside the housing, and a rotating rod is rotatably fitted inside the housing. A push rod is slidably fitted on one side of the housing, with one end of the push rod engaging with the stop bar. A constraint rod is installed on the rotating rod, which engages with a telescopic baffle. A limit rod is installed on the rotating rod, which engages with the stop bar.

[0014] Optionally, the test frame includes a base plate, two uprights mounted on the upper side of the base plate, a top plate mounted on the upper side of the two uprights, a placement pad mounted on the upper side of the base plate, a housing mounted on one side of the top plate, and a telescopic baffle mounted on the lower side of the top plate.

[0015] Optionally, the traction device includes a motor, with a winding roller installed at the output end of the motor. A traction rope is wound on the winding roller, and one end of the traction rope passes through the top plate and is fixedly connected to the unhooking device.

[0016] Optionally, the impact device includes a crossbar that is slidably fitted between two uprights, a connecting shell mounted on the crossbar, a connecting ring mounted on the connecting shell, and an impact head detachably mounted on the underside of the connecting shell.

[0017] Optionally, grooves are provided on the opposite inner surfaces of the two uprights, a limiting groove is provided on one side of the groove, and limiting slide plates are installed at both ends of the crossbar, with the limiting slide plates slidingly engaged in the limiting groove.

[0018] Optionally, one side of the limiting slide plate is elastically fitted with multiple rollers, which fit tightly against one side of the limiting groove.

[0019] Optionally, the upper side of the crossbar is provided with multiple positioning holes, the connecting shell is sleeved and slidably fitted on the crossbar, and a positioning rod is installed on the top of the inner wall of the connecting shell, the positioning rod cooperating with the positioning holes.

[0020] Optionally, the bottom of the inner wall of the positioning rod is elastically fitted with a compression plate, which cooperates with the crossbar.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0022] 1. The traction device uses a motor-driven winding roller to wind the traction rope, achieving automated lifting and lowering of the unhooking device and impact device. Compared to manual lifting, this structure can control the lifting height of the impact device, ensuring consistent initial conditions for multiple tests and improving the repeatability of test data; it also reduces labor costs and improves testing efficiency.

[0023] 2. The crossbar of the impact device slides in the limiting groove of the upright through the limiting slide plates at both ends. With the guiding effect of the slide groove, the tilt or offset of the crossbar is limited, so that the impact head falls vertically and reduces the test error caused by the deviation of the motion trajectory.

[0024] 3. The restraint components of the protective device enable the rapid deployment of the retractable baffle through the mechanical linkage of the push rod, stop rod, and rotating rod. After pressing the push rod, its inclined surface compresses the stop rod to slide, releasing the obstruction of the limit rod. The rotating rod drives the restraint rod to rotate and release the retractable baffle, which quickly covers the test frame and forms a sealed space with the top and bottom plates. This prevents the risk of fragments flying or battery explosion during impact (such as mobile phone testing), thus improving operational safety.

Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] Please see Figure 1-5 As shown, this embodiment provides an automated testing device for a decoupling system, including:

[0043] Test fixture 1;

[0044] Unhooking device 2;

[0045] The traction device 3 is installed on the top of the test frame 1, and the traction end of the traction device 3 is fixedly connected to the unhooking device 2.

[0046] Impact device 4 is slidably fitted inside test frame 1 and cooperates with unhooking device 2;

[0047] Protective device 5, which includes a retractable baffle 6 and a restraint assembly 7;

[0048] The constraint assembly 7 includes a housing 701, which is installed on one side of the test frame 1. A stop bar 702 is slidably fitted inside the housing 701, and a rotating rod 703 is rotatably fitted inside the housing 701. A push rod 704 is slidably fitted on one side of the housing 701, and one end of the push rod 704 cooperates with the stop bar 702. A constraint rod 705 is installed on the rotating rod 703, and the constraint rod 705 cooperates with the telescopic baffle 6. A limit rod 706 is installed on the rotating rod 703, and the limit rod 706 cooperates with the stop bar 702.

[0049] Working principle:

[0050] The traction device 3 is connected to the impact device 4 via the unhooking device 2. After connection, the impact device 4 is pulled to the required height position for testing via the traction device 3. Then, the mobile phone to be impacted is placed on the test frame 1, and the unhooking device 2 is activated. The unhooking device 2 disconnects from the impact device 4, allowing the impact device 4 to fall freely. The impact device 4 impacts the mobile phone, thus completing the impact test.

[0051] During the mobile phone impact test, there may be unexpected situations such as fragments flying due to the impact. Therefore, before releasing the impact device 4 through the release device 2, the push rod 704 can be pressed manually. The push rod 704 pushes the stop rod 702, and the stop rod 702 releases the obstruction of the limit rod 706. At this time, the constraint rod 705 will be continuously squeezed by the retractable baffle 6, so it will rotate through the rotating rod 703 to release the constraint on the retractable baffle 6. The retractable baffle 6 extends to cover the test frame 1, which can prevent the occurrence of accidents. In the event of battery explosion after the impact test, the above steps can be followed to quickly release the retractable baffle 6 to cover the test frame 1, achieving a rapid protection effect.

[0052] The test frame 1 in this embodiment includes a base plate 101, two uprights 102 mounted on the upper side of the base plate 101, a top plate 103 mounted on the upper side of the two uprights 102, a placement pad 104 mounted on the upper side of the base plate 101, a housing 701 mounted on one side of the top plate 103, and a retractable baffle 6 mounted on the lower side of the top plate 103. The retractable baffle 6 is a plurality of sequentially nested rectangular annular baffles, as in the prior art, used to cover the test frame 1 during descent, and cooperates with the top plate 103 and the base plate 101 to form a sealed space, achieving a protective effect. Furthermore, to facilitate observation of the internal condition of the test frame 1 by the operator, the rectangular annular baffles can be made of transparent plastic sheets, as in the prior art.

[0053] The traction device 3 in this embodiment includes a motor, and a winding roller is installed at the output end of the motor. A traction rope 301 is wound on the winding roller, and one end of the traction rope 301 passes through the top plate 103 and is fixedly connected to the unhooking device 2.

[0054] The motor is designed to drive the winding roller to rotate, which in turn causes the winding roller to wind up the traction rope 301, thereby driving the unhooking device 2 to rise.

[0055] The impact device 4 in this embodiment includes a crossbar 401, which is slidably fitted between two uprights 102. A connecting shell 402 is mounted on the crossbar 401, and a connecting ring 403 is mounted on the connecting shell 402. An impact head 404 is detachably mounted on the lower side of the connecting shell 402.

[0056] The horizontal bar 401 can slide between the two vertical bars 102 to guide the impact head 404. The impact head 404 can be replaced with an impact head 404 with a flat, conical or arc-shaped end according to the actual needs of the impact test.

[0057] In this embodiment, each of the two uprights 102 has a sliding groove 105 on its opposite inner side. A limiting groove 106 is provided on one side of the sliding groove 105. Both ends of the crossbar 401 are equipped with limiting slide plates 405, which slide in the limiting groove 106.

[0058] The limiting slide plate 405 is designed to slide within the limiting groove 106, reducing the likelihood of the crossbar 401 tilting within the groove 105.

[0059] In this embodiment, a plurality of rollers 406 are elastically fitted on one side of the limiting slide plate 405, and the rollers 406 are tightly fitted to one side of the limiting groove 106.

[0060] By using the roller 406, the friction between the limiting slide plate 405 and the limiting groove 106 can be reduced, thus reducing the impact of friction on the free fall speed of the impact head 404. Furthermore, the roller 406 fits tightly against the limiting groove 106, which can further improve the stability of the crossbar 401 sliding between the two uprights 102.

[0061] In this embodiment, the upper side of the crossbar 401 is provided with a plurality of positioning holes 407, the connecting shell 402 is sleeved and slidably fitted on the crossbar 401, and the top of the inner wall of the connecting shell 402 is provided with a positioning rod 408, which cooperates with the positioning holes 407.

[0062] The positioning hole 407 allows the operator to lift the connecting shell 402 to disengage the positioning rod 408 from the positioning hole 407. At this time, the connecting shell 402 can be slid to adjust the position of the impact head 404. After reaching the appropriate position, the connecting shell 402 can be released to allow the positioning rod 408 to be reinserted into the positioning hole 407.

[0063] In this embodiment, the bottom of the inner wall of the positioning rod 408 is elastically fitted with a pressing plate 409, which cooperates with the crossbar 401.

[0064] The compression plate 409 is designed to fill the gap between the connecting shell 402 and the crossbar 401, reducing the possibility of the connecting shell 402 shifting position on the crossbar 401 during traction. The added compression plate 409 only needs to constrain the position of the crossbar 401 when adjusting the connecting shell 402. Pulling the connecting shell 402 to compress the compression plate 409 can adjust the position of the connecting shell 402 in the manner described above. After the adjustment is completed, the compression plate 409 returns to its original position through elasticity, filling the gap between the connecting shell 402 and the crossbar 401.

[0065] In this embodiment, a threaded rod is installed on the lower side of the connecting shell 402, and a threaded cylinder is installed on the upper side of the impact head 404. The threaded cylinder and the threaded rod are threadedly engaged.

[0066] In this embodiment, the push rod 704 has an inclined surface at one end near the stop rod 702. The inclined surface allows the stop rod 702 to rise as the user pushes the push rod 704, thus releasing the stop rod 702 from blocking the limit rod 706.

[0067] In this embodiment, the constraint rod 705 is L-shaped. The constraint rod 705 is provided with a first rod body and a second rod body, and the first rod body is connected to the second rod body. The included angle between the first rod body and the second rod body is an obtuse angle, and the obtuse angle is directed towards the retractable baffle 6.

[0068] The unhooking device 2 is existing technology and will not be described in detail here.

[0069] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.

[0070] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
