Description

TECHNICAL FIELD

[0001] The present application relates to the field of mobile phone screen detection, and in particular to a mobile phone display screen pressure detector. BACKGROUND

[0002] In the existing mobile phone screen pressure detection, the screen is installed on the mobile phone for detection, which has the following problems.

[0003] 1. In the existing simulation of mobile phone pressure detection, the mobile phone screen is usually pressed by a flexible object with a width relative to the mobile phone to simulate the process of the mobile phone screen being crushed by a wheel. The result of the above-mentioned detection is too single and cannot simulate the real scene when the mobile phone screen is crushed by a wheel.

[0004] 2. In the simulation of mobile phone screen pressure detection, the existing technology usually fixes the mobile phone on both sides and directly presses the mobile phone screen with a cylinder to perform extreme detection. The extreme detection of the mobile phone screen by the above-mentioned method is too limited and can only detect the bearing capacity of a point on the mobile phone screen. Since the mobile phone is fixed on both sides during the detection, the fixation on both sides causes the mobile phone to be unable to disperse the pressure downward during the extreme detection, resulting in inaccurate detection data.

[0005] 3. In the simulation of the mobile phone screen being subjected to multiple impacts in a short time, the mobile phone screen is usually pressed by a cylinder with the same force in a short time to simulate the situation of being subjected to multiple impacts. The result obtained by the above-mentioned method is significantly different from the result of an actual object falling onto the mobile phone screen to cause multiple impacts. Since the mobile phone screen is subjected to the greatest force when the object initially falls onto it, the force and direction of the subsequent impacts change, and the repeated impacts at the same position with the same force are different.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] A pressure detector for mobile phone displays, such as Figures 1-3 As shown, it includes a mounting frame 1, an electric base 2, and a fixing plate 3; the mounting frame 1 has a viewing window 1a on the front side and a handle 1b on the rear side; the electric base 2 is bolted to the bottom of the mounting frame 1; the fixing plate 3 is slidably connected to the electric base 2.

[0031] The first air bag 4, the first push rod 5, the second air bag 6, the transmission assembly, the tilt fixing assembly, the extrusion detection assembly and the impact detection assembly are further included; four tilt fixing assemblies in annular distribution are installed on the electric seat 2; two extrusion detection assemblies in annular distribution are installed on the inner top surface of the installation frame 1; one impact detection assembly is installed on each of the two extrusion detection assemblies, and the two impact detection assemblies are in annular distribution; the transmission assembly is installed on the inner top surface of the installation frame 1 and is located between the two extrusion detection assemblies; the first air bag 4 is rotatably connected to the bottom of the transmission assembly; the first push rod 5 opposite to the two telescopic parts is fixedly connected in the first air bag 4; the second air bag 6 is fixedly connected to the two first push rods 5 in common, and the extrusion part 6a is arranged on the second air bag 6.

[0032] The convex point 4a is arranged on the first air bag 4, which is used for simulating the condition that the wheel gap has stones.

[0033] The multiple impact detection assembly adjusts the state of the extrusion detection assembly to avoid affecting the detection of the mobile phone screen during the pressure detection of the detection of the mobile phone screen. When the mobile phone screen needs to be simulated by the wheel, the mobile phone is first placed on the fixed plate 3 connected to the electric seat 2. The electric seat 2 drives the fixed plate 3 and the mobile phone to move to the center of the installation frame 1. The first guide rail 101 and the moving block 102 in the transmission assembly are used to control the left or right movement of the first air bag 4, the first push rod 5 and the second air bag 6. The electric rotating seat 103 is used for the rotation of the first air bag 4, the first push rod 5 and the second air bag 6. The second push rod 104 is used to control the lifting of the first air bag 4, the first push rod 5 and the second air bag 6. The second guide rail 105 and the mounting seat 106 are used to control the forward or backward movement of the first air bag 4, the first push rod 5 and the second air bag 6. The transmission assembly drives the first air bag 4, the first push rod 5 and the second air bag 6 to move to the center of the installation frame 1. When the mobile phone is located in the center of the installation frame 1, the fixed plate 3 stops moving, and the transmission assembly stops moving. From the top view, the transmission assembly is one to two centimeters away from the mobile phone. The middle part of the mobile phone is fixed by the inclined fixed assembly. Then the second push rod 104 pushes out to drive the first air bag 4, the first push rod 5, the second air bag 6, the second guide rail 105 and the mounting seat 106 to move downward. After the first air bag 4 contacts the fixed plate 3, the pressure detector 104a starts to detect the pressure. When the pressure reaches a specified pressure, the second push rod 104 stops pushing out. The first air bag 4, the first push rod 5 and the second air bag 6 are driven by the transmission assembly to crush the mobile phone screen to simulate the crushing of the mobile phone screen by the wheel. The convex point 4a simulates the situation that the wheel gap has stones. When the first air bag 4, the first push rod 5 and the second air bag 6 move linearly, the electric rotating seat 103 is used to rotate to simulate the situation that the mobile phone screen is crushed by the wheel in the turning. The second guide rail 105 and the mounting seat 106 control the position of the first air bag 4, the first push rod 5 and the second air bag 6 to simulate the situation that the mobile phone screen is partially crushed by the wheel. The first push rod 5 pushes out to extrude the extrusion part 6a, so that the second air bag 6 expands outward to support the middle part of the first air bag 4, simulating the crushing of the wheel of the small trolley loaded with goods.

[0034] Example 2

[0035] Based on example 1, as Figure 4As shown, the front right tilting fixing assembly includes a third push rod 201, a connecting strip 202, a first rotating plate 203, a second rotating plate 204, and a suction cup 205; the third push rod 201 is fixedly connected in the electric seat 2; the connecting strip 202 is slidingly connected to the electric seat 2, and the front side of the connecting strip 202 is fixedly connected to the telescopic part of the third push rod 201; the first rotating plate 203 is rotatably connected to the rear side of the connecting strip 202; the second rotating plate 204 is rotatably connected to the first rotating plate 203, and the left part of the second rotating plate 204 is rotatably connected to the electric seat 2; at least three suction cups 205 are fixedly connected to the second rotating plate 204, and a gas pump is arranged in the suction cup 205.

[0036] When the pressure detection of the mobile phone screen is performed, for example, when the mobile phone needs to be tilted in the front right direction, the third push rod 201 in the front right direction is retracted to drive the connecting strip 202 in the front right direction to move to the left. At this time, the mobile phone is simply fixed by the suction cup 205 on the center of the second rotating plate 204 in the front right direction. Because the mobile phone is pressed in a tilted manner in the actual scene, the mobile phone is not fixed too strongly, so when the pressure detection of the mobile phone screen is performed, the mobile phone cannot be fixed too strongly to avoid affecting the accuracy of the detection result. The first rotating plate 203 in the front right direction and the second rotating plate 204 in the front right direction are turned upward, and at this time, the mobile phone is fixed in the installation frame 1 in a manner that the left is low and the right is high. The pressure detection assembly is started to perform the pressure detection of the mobile phone screen. After that, the above-mentioned actions are repeated, the tilting fixing assembly in different directions is adjusted to change the tilting direction of the mobile phone, the pressure detection of the mobile phone screen in different tilting states is simulated, and the mobile phone can be fixed in different degrees by controlling different numbers of suction cups 205 to simulate the pressure detection of the mobile phone screen in more different scenes.

[0037] Embodiment 3

[0038] On the basis of embodiment 2, as shown, Figure 5 the rear pressure detection assembly includes a fourth push rod 301, a fixed strip 302, a driving motor 303, and a pressing plate 304; the fourth push rod 301 is fixedly connected to the inner top surface of the rear side of the installation frame 1; the telescopic part of the fourth push rod 301 is fixedly connected to the fixed strip 302, and the first recess 302a is formed in the fixed strip 302; the driving motor 303 is bolted to the left side of the fixed strip 302; the output shaft of the driving motor 303 is fixedly connected to the pressing plate 304 through the fixed strip 302, the second recess 304a is formed in the pressing plate 304, and the second recess 304a cooperates with the first recess 302a.

[0039] The pressing plate 304 is designed in a fan shape, and the angle of the pressing plate 304 is adjusted by cooperating with the driving motor 303, so that the pressing plate 304 can simulate the pressing of more objects on the mobile phone screen.

[0040] In the process of simulating the mobile phone screen being crushed by the wheels, the two driving motors 303 rotate to drive the respective connecting plates 304 to rotate 125 degrees in the direction of the connected impact detection assemblies, so as to avoid affecting the movement of the transmission assembly.

[0041] When the extrusion detection assembly performs local pressure detection on the mobile phone screen, the fourth push rod 301 is pushed to drive the fixed strip 302, the driving motor 303 and the pressing plate 304 to move downward to extrude the mobile phone screen. The driving motor 303 adjusts the rotation angle of the pressing plate 304 to perform pressure detection on different areas of the mobile phone screen. At the same time, the driving motor 303 can be rotated to make the second groove 304a and the first groove 302a fit together, and the two fixed strips 302 and the two pressing plates 304 are connected as a whole, so that different areas of the mobile phone screen can be simultaneously subjected to pressure detection.

[0042] Embodiment 4

[0043] Based on embodiment 3, as shown in Figure 6 The rear impact detection assembly includes a fifth push rod 401, a connecting block 402, a sliding rod 403 and an impact unit. The fifth push rod 401 is fixedly connected to the left side of the fixed strip 302 and located to the right of the driving motor 303. The fifth push rod 401 is fixedly connected to the connecting block 402. The connecting block 402 is connected to the front side of the impact unit.

[0044] The impact unit includes a first circular ring 410, a spring 411 and a second circular ring 412. The connecting block 402 is slidingly connected to the sliding rod 403. The first circular ring 410 is fixedly connected to the sliding rod 403. The first circular ring 410 is fixedly connected to the surface of the three annular springs 411. All the springs 411 are connected to the second circular ring 412.

[0045] The second circular ring 412 can be deformed, so that the detection result of the mobile phone screen can be closer to reality.

[0046] In the process of carrying out the mobile phone screen pressure detection, the impact detection assembly simulates the situation that the mobile phone screen is subjected to multiple impacts in a short time. The fifth push rod 401 pushes out or retracts to drive the connecting block 402, the slide rod 403, the first circular ring 410, the spring 411 and the second circular ring 412 to move forward or backward, thereby adjusting the detection position of the mobile phone screen. Before the impact detection assembly detects, the second circular ring 412 needs to be extruded by rotating the pressure plate 304 through the control driving motor 303. After the second circular ring 412 is extruded, the second circular ring 412 moves upward, and the spring 411 located at the lower left begins to contract, and the spring 411 located at the upper right and lower right begins to stretch. The impact unit starts to store energy, and the impact unit drives the slide rod 403 to slide upward, and the fifth push rod 401 pushes out to lower the impact detection assembly to the specified position. After the pressure plate 304 loses contact with the second circular ring 412, the impact unit starts to release the accumulated energy, and the impact unit impacts the mobile phone screen downward. After the impact unit contacts the mobile phone screen, the second circular ring 412 impacts the mobile phone screen. After the second circular ring 412 completes the first impact on the mobile phone screen, the three springs 411 quickly change between the contraction and stretching states, drive the second circular ring 412 to impact different positions of the mobile phone screen with different forces, and better simulate the reaction of the object falling on the mobile phone screen.

[0047] The sixth push rod 501 and the pressing block 502 are also included. Four sixth push rods 501 are fixedly connected to the top surface of the mounting frame 1 in a rectangular distribution. Each extension of the sixth push rod 501 is fixedly connected with a pressing block 502. The two pressing blocks 502 on the left and the two pressing blocks 502 on the right are symmetrically distributed front and back.

[0048] The pressing block 502 is arc-shaped and has a soft pad on the bottom surface, which can simultaneously adapt to the pressure maintaining treatment of conventional screens and curved screens and reduce the damage to the screen during the pressure maintaining treatment.

[0049] When different mobile phone screens need to be detected, the original mobile phone screen has been broken and needs to be replaced. After the mobile phone screen is replaced, pressure maintaining is needed. At this time, the mobile phone with the replaced screen is placed in the detection area of the mounting frame 1, and then the sixth push rod 501 pushes out to extrude the pressing block 502 on the mobile phone screen to maintain the pressure of the mobile phone. After the pressure maintaining is completed, the sixth push rod 501 retracts to drive the pressing block 502 to return to the initial position, and the pressure detection of the mobile phone screen can be directly carried out.

[0050] Finally, it should be noted that the above examples are merely intended to illustrate the technical solutions of the present application and not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present application.
