Description

Technical Field

[0001] This application relates to the field of product pressure testing, and in particular to a remote control button pressure testing mechanism based on pneumatic load. Background Technology

[0002] In the field of electronic equipment manufacturing, remote controls, as commonly used control devices, rely heavily on the performance of their buttons. With continuous technological advancements, remote control functions are becoming increasingly diverse, and users are placing higher demands on the ease of operation and stability. Button pressure testing, as a crucial step in ensuring remote control quality, is of great significance for guaranteeing product reliability and user experience. Accurate button pressure testing can effectively prevent operational malfunctions and misoperations caused by abnormal button pressure, thereby improving the overall quality and market competitiveness of remote controls. In emerging fields such as smart homes and smart appliances, the application scenarios for remote controls are constantly expanding, posing even greater challenges to the accuracy and efficiency of button pressure testing. Therefore, the development of related technologies is of significant value in driving the progress of the electronic equipment industry.

[0003] Existing remote control button pressure testing typically employs two methods: manual testing and simple mechanical testing. Manual testing involves operators using simple pressure testing tools, such as pressure gauges, to press each button on the remote control one by one. While simple to operate, this method is inefficient, and due to human error, the accuracy and consistency of the test results are difficult to guarantee, failing to meet the needs of large-scale production. Simple mechanical testing uses mechanical devices to apply a fixed pressure to the buttons, recording the button feedback information through sensors. However, this method lacks precise control over air pressure and load, failing to simulate the complexities of actual use, resulting in inaccurate test results. Furthermore, existing testing methods require frequent adjustments to the testing equipment when dealing with different models and specifications of remote controls, increasing testing costs and time.

[0004] Therefore, how to design a testing mechanism that can accurately control the test pressure and adapt to different models and specifications of remote controls for pressure testing is a technical problem that urgently needs to be solved. Utility Model Content

One end of the second mounting base plate is connected to the first mounting base plate via a screw, and a spring component is sleeved on the screw to buffer the downward movement of the load test component. The corresponding convex edge plate is provided with a through hole for the screw and the spring component to pass through.

Detailed Implementation

[0026] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0027] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0028] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0029] See Figure 1 and Figure 2 The present application discloses a remote control button pressure testing mechanism based on air pressure load, which includes a machine base 10, a first drive structure 20, a second drive structure 30 and a pressure testing structure 40.

[0030] The machine tool 10 is equipped with a support frame 11 and a housing 12. The housing 12 is used to hold the remote control under test. A first drive structure 20 is fixed on the support frame 11, and a second drive structure 30 is fixed on the machine tool 10 to drive the housing 12 to move the remote control under test linearly. One side of the first mounting plate 41 of the pressure testing structure 40 is connected to the first drive structure 20. The air pressure component 42 is connected to the load testing component 43 and is also located on the side of the first mounting plate 41 away from the first drive structure 20. One end of the load testing component 43 has a test pressure head 431 exposed. The first drive structure 20 drives the pressure testing structure 40 to move towards the position of the remote control under test, and the test pressure head 431 presses down on the remote control under test under the air pressure control of the air pressure component 42. In this way, the relative position of the pressure testing structure 40 and the remote control under test can be flexibly adjusted by the cooperation of the first drive structure 20 and the second drive structure 30; and the air pressure and load can be precisely controlled according to actual needs by the cooperation of the air pressure component 42 and the load testing component 43 to adjust the test pressure.

[0031] Specifically, the testing platform 10 is the basic support component of the entire testing mechanism. It is made of sturdy metal materials, such as stainless steel or aluminum alloy, to ensure its stability and durability. Of course, it can also be made of high-strength plastic, etc., but this embodiment is not limited. The support frame 11 on the testing platform 10 is a frame structure that supports the first drive structure 20. It is fixed to the testing platform 10 by welding or bolting, which facilitates the installation of the first drive structure 20. The receiving box 12 is provided with multiple receiving slots for placing the remote control to be tested. Its shape and size are not limited and can be designed according to the specifications of common remote controls.

[0032] The first drive structure 20 includes a first direction drive assembly 21 and a second direction drive assembly 22. The first direction drive assembly 21 is horizontally fixed on the support frame 11 and can move horizontally using a motor and lead screw drive. The motor can be a stepper motor, which has precise control performance. The lead screw drive can convert the rotational motion of the motor into linear motion, driving the second direction drive assembly 22 to move along the first direction (such as the X-axis). The second direction drive assembly 22 is a cylinder drive assembly, vertically fixed on the first direction drive assembly 21. Of course, in another embodiment, it can also be in the form of a motor and lead screw drive to drive the first mounting base plate 41 and the test pressure head 431 to move along the second direction (such as the Z-axis). The first direction and the second direction are perpendicular to each other.

[0033] The second drive structure 30 is fixed on the machine base 10 and is used to drive the housing 12 to move the remote control under test linearly along a third direction (such as the Y-axis). In this embodiment, its specific structure is not limited, as long as it can drive the housing 12 to move linearly. For example, it can be a cylinder drive mechanism, consisting of a cylinder and a piston. The gas in the cylinder pushes the piston to move, thereby moving the housing 12. It can also be an electric push rod drive mechanism, in which a motor drives the push rod to extend and retract, thereby realizing the linear movement of the housing 12. In this way, in conjunction with the design of the first drive structure 20, the pressure testing structure 40 can move flexibly in three-dimensional space and accurately align with each button of the remote control under test.

[0034] See Figure 2 and Figure 3 The first mounting base plate 41 of the pressure testing structure 40 is a key component connecting the first drive structure 20, the pneumatic assembly 42, and the load testing assembly 43. If made of metal sheet, it has a certain strength and rigidity. One side of it is connected to the first drive structure 20 by bolts or welding to ensure the stability of the connection.

[0035] The pneumatic assembly 42 is connected to the load testing assembly 43 via an air pipe. The pneumatic assembly 42 may include a pneumatic pump, an air pipe, and a pneumatic pressure regulating valve. The pneumatic pump is used to generate air pressure, the air pipe is used to transmit air pressure, and the pneumatic pressure regulating valve can precisely control the air pressure.

[0036] See Figure 3 and Figure 4 The load testing assembly 43 includes a test indenter 431, a connector 432, a first outer sleeve 433, a piston rod 434, and a second outer sleeve 435. One side of the connector 432 is fixed to the second mounting base plate 44 by screws, and a first air inlet port 4321 is provided on one end face for connecting to the pneumatic assembly 42. The connector 432 can be made of stainless steel, which has good corrosion resistance. One end of the first outer sleeve 433 is embedded in the connector 432 and communicates with the first air inlet port 4321, ensuring smooth gas transmission and allowing the piston rod 434 to move accurately downwards under the push of the gas.

[0037] The piston rod 434 is located inside the first outer sleeve 433 and is pushed downward by the gas entering through the first air inlet port 4321. One end of the second outer sleeve 435 is connected to the first outer sleeve 433, and a second air inlet port 4351 connected to the air pressure assembly 42 is provided on one side. One end of the test pressure head 431 is located inside the second outer sleeve 435 and abuts against the end of the piston rod 434 away from the first air inlet port 4321, and is used to move downward with the piston rod 434 and the gas entering through the second air inlet port 4351.

[0038] See Figure 4To increase the airtightness of the load testing assembly 43, the load testing assembly 43 also includes a first inner sleeve 436 and a second inner sleeve 437. The first inner sleeve 436 is located inside the first outer sleeve 433 for the piston rod 434 to pass through. The first outer sleeve 433, the first inner sleeve 436, and one end of the piston rod 434 surround a first sealed space 4361, which can provide a stable space for the movement of the piston rod 434, so that the piston rod 434 moves down stably under the push of the gas entering through the first air inlet port 4321. The second inner sleeve 437 is located inside the second outer sleeve 435 for the test head 431 to pass through. The second outer sleeve 435, the second inner sleeve 437, and one end of the test head 431 surround a second sealed space 4371, which can provide a stable space for the movement of the test head 431, so that the test head 431 moves down stably under the push of the piston rod 434 and the gas entering through the second air inlet port 4351.

[0039] In this embodiment, both the first outer sleeve 433 and the second outer sleeve 435 are made of acetal alloy (polyoxymethylene (POM)), which has excellent mechanical properties, wear resistance, and chemical resistance. The first inner sleeve 436, the second inner sleeve 437, the piston rod 434, and the test indenter 431 are all made of SKD11 high-carbon high-chromium cold work tool steel, which has high hardness, good cutting stability, excellent wear resistance, and good heat treatment performance.

[0040] See Figure 2 and Figure 5 The pressure testing structure 40 also includes a second mounting base plate 44, connected to the end face of the first mounting base plate 41 away from the first driving structure 20. A guide groove 441 is provided on one side of the second mounting base plate 44, and a guide rail 412 is provided on the first mounting base plate 41 corresponding to the guide groove 441. This cooperation between the guide rail 412 and the groove ensures the stability and accuracy of the load testing component 43 during movement. Multiple load testing components 43 are configured and arranged side-by-side on the second mounting base plate 44, allowing simultaneous testing of multiple buttons and improving testing efficiency.

[0041] Furthermore, a raised edge plate 411 perpendicular to the first mounting base plate 41 is provided thereon. The pneumatic assembly 42 is located at the end of the raised edge plate 411 away from the load testing assembly 43 and abuts against the raised edge plate 411. One end of the second mounting base plate 44 is connected to the first mounting base plate 41 via a screw 45, and a spring member 46 for buffering the downward movement of the load testing assembly 43 is sleeved on the screw 45. A through hole 4111 is provided on the corresponding raised edge plate 411 for the screw 45 and the spring member 46 to pass through. The function of the spring member 46 is to buffer the downward movement of the test head 431 and avoid excessive damage to the button.

[0042] See Figure 4A silicone sleeve 4311 is fitted on the exposed end of the test head 431. The silicone sleeve 4311 has good flexibility and wear resistance, which can better simulate the feeling of pressing the button by a human hand, while protecting the button surface from damage.

[0043] See Figure 1 and Figure 3 In this embodiment, a limiting component 50 is also included. The limiting component 50 includes a limiting member 51 and a limiting switch 52. One end of the limiting member 51 is fixed to the flange plate 411, and the limiting switch 52 is fixed relative to the limiting member 51 on the second mounting base plate 44. The function of the limiting component 50 is to limit the movement range of the pressure testing structure 40 to prevent excessive movement that could damage the equipment or cause inaccurate testing.

[0044] The implementation principle of this embodiment is as follows: The testing mechanism provides stable support through the machine base 10. The cooperation of the first drive structure 20 and the second drive structure 30 enables the position adjustment of the pressure testing structure 40 and the remote control under test in different directions. The pneumatic component 42 and the load testing component 43 cooperate to precisely control the downward pressure of the test pressure head 431, simulating complex situations in actual use. The setting of multiple load testing components 43 allows for simultaneous testing of multiple buttons, improving testing efficiency. The setting of the spring component 46 and the limiting component 50 ensures the safety and stability of the testing process, avoiding damage to the remote control.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
