Automated testing equipment for durability of mechanical buttons of car audio

Abstract

This utility model discloses an automated testing device for the durability of mechanical buttons in car audio systems, relating to the field of automotive parts testing. It includes a testing frame with a positioning rod fixedly connected to its upper end. This utility model uses a guide rail to allow the first tightening frame to move. When the position of the testing rod needs adjustment, the operator rotates the first tightening frame so that its narrower side faces the guide rail. The guide rail can slide freely along the lifting frame. Once the position is adjusted, the operator rotates the first tightening frame clockwise or counterclockwise, causing its wider side to gradually approach and eventually contact the guide rail surface. This creates a compressive force on the first tightening frame, forcing a first rubber block at one end of the first tightening frame to fit tightly against the surface of the lifting frame. Friction quickly locks the position of the first tightening frame. This device is suitable for frequent model changes in testing various types of car audio buttons, effectively improving the equipment's operational efficiency and positioning stability.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing, specifically an automated testing device for the durability of mechanical buttons in car audio systems. Background Technology

[0002] As an important part of the car interior, the durability of the mechanical buttons in car audio systems directly affects user experience and product reputation. With the rapid development of the automotive industry, consumers are increasingly demanding higher usage frequency and reliability of car audio systems. As high-frequency operating components, the lifespan and tactile stability of mechanical buttons have become key factors in measuring product quality. Therefore, an automated testing device for the durability of mechanical buttons in car audio systems is needed.

[0003] Existing automated testing equipment for the durability of mechanical buttons in car audio systems suffers from a significant decrease in versatility when faced with diverse testing requirements. It fails to meet the practical needs of "multi-specification compatibility" in automotive component testing. Mechanical buttons in car audio systems are typically located in specific panel areas, and the number, arrangement, and size of buttons vary between different products. Furthermore, the center point of each button needs precise alignment, which can easily lead to distorted test data due to misalignment. Additionally, the components in contact with the buttons are not easily fixed or adjusted quickly. Therefore, there is an urgent need for automated testing equipment for the durability of mechanical buttons in car audio systems. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an automated testing device for the durability of mechanical buttons in car audio systems. This addresses the problem that existing automated testing devices for the durability of mechanical buttons in car audio systems suffer from a significant decrease in versatility when faced with diverse testing needs. They fail to meet the practical requirements of "multi-specification compatibility" in automotive parts testing. The mechanical buttons in car audio systems are typically distributed in specific panel areas, and the number, arrangement, and size of buttons vary between different products. Furthermore, the center point of the same button needs to be precisely aligned, which can easily lead to distorted test data due to misalignment. Additionally, the components in contact with the buttons are not easily fixed and adjusted quickly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated testing device for the durability of mechanical buttons in a car audio system, comprising a testing frame, a positioning rod fixedly connected to the upper end of the testing frame, a PLC controller fixedly connected to the outer wall of the positioning rod, an anti-slip pad adhered to the inner wall of the testing frame, electric push rods installed on both sides of the testing frame, a support frame installed at one end of each electric push rod, a fixing rod fixedly connected to the inner wall of each support frame, a synchronous motor fixedly connected to the outer wall of each fixing rod, a contact rotor fixedly connected to one end of each synchronous motor, a lifting frame abutting the outer wall of the contact rotor, a first spring abutting the outer wall of each lifting frame, a guide rail installed on the inner wall of each lifting frame, a second spring abutting at both ends of each guide rail, a first tightening frame abutting at one end of each second spring, a first rubber block adhered to the outer wall of the first tightening frame, and a first locking frame installed at one end of the first tightening frame.

[0006] A detection rod is installed on the inner wall of the guide rail. A third spring abuts against the outer wall of the detection rod. One end of the third spring abuts against a second tensioning frame. A second rubber block is adhered to the outer wall of the second tensioning frame. A second locking frame is installed at one end of the second tensioning frame. A laser light is installed at the upper end of the detection rod. A silicone button mold head is installed at the lower end of the detection rod. A Bluetooth 5.3 connection module is electrically connected to one side of the PLC controller. A Wi-Fi 6E connection module is electrically connected to one side of the Bluetooth 5.3 connection module.

[0007] Preferably, the lifting frame is movably connected to the testing frame, and the inner wall of the lifting frame has a slotted design.

[0008] Preferably, the guide rail is engaged with the first tensioning frame, and the first tensioning frame is symmetrically arranged about the central axis of the guide rail.

[0009] Preferably, the outer wall of the first tightening frame is in close contact with the outer wall of the first rubber block, and the first rubber block is square in shape.

[0010] Preferably, the first tightening frame is movably connected to the first locking frame, and the inner wall of the first tightening frame has an open design.

[0011] Preferably, the detection rod is snapped into place with the laser lamp, and the inner wall of the detection rod has an open design.

[0012] Preferably, the outer wall of the detection rod is in close contact with the inner wall of the silicone button mold head, and the diameter of the outer wall of the detection rod is smaller than the diameter of the inner wall of the silicone button mold head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a guide rail to enable the first tightening frame to move. When the position of the detection rod needs to be adjusted, the operator rotates the first tightening frame so that the narrower side faces the guide rail. The first tightening frame is in a relaxed state, and the guide rail can slide freely along the lifting frame. After the position is adjusted, the operator rotates the first tightening frame clockwise or counterclockwise so that the wider side gradually approaches the surface of the guide rail and eventually contacts it. Since the size of the wider side is larger than the initial gap, it will exert a squeezing force on the first tightening frame, forcing the first rubber block at one end of the first tightening frame to fit tightly against the surface of the lifting frame. The friction force quickly locks the position of the first tightening frame, which retains the flexible adjustment capability of the traditional guide rail and solves the problem of quick fixation. It is suitable for frequent model change scenarios in the testing of various types of car audio buttons, effectively improving the operating efficiency and positioning stability of the equipment.

[0015] 2. This utility model uses a detection rod to lock and fix the laser light. The detection rod serves as both the mounting carrier and positioning actuator for the laser light. Made of high-strength, lightweight alloy material, the detection rod is elongated and has a matching slot at one end for the laser light. The operator simply inserts the laser light into the slot to complete the installation without additional tools. The hollow channel of the detection rod is completely coaxial with the laser beam emission direction, ensuring unobstructed laser beam emission from one end of the detection rod. When the laser light is powered on, the beam is transmitted through the hollow channel to the front end of the detection rod, forming a visible green laser dot. During positioning, the operator simply aligns the front end of the detection rod with the car audio button panel and fine-tunes the alignment between the laser dot and the center point of the button. If the laser dot deviates from the center of the button, the detection rod is pushed along the guide rail until the light spot completely covers the center of the button. Meanwhile, the Bluetooth 5.3 module supports both BLE and BR / EDR dual modes and is compatible with previous versions of Bluetooth 5.0, 5.1, and 5.2. It can simulate pairing scenarios between car audio systems and mobile phones or car Bluetooth devices. The Wi-Fi 6E module supports the 6GHz band and is backward compatible with Wi-Fi 5 and Wi-Fi 4 protocols. It can simulate wireless connections between car audio systems and in-vehicle infotainment systems or smart home devices. During button durability testing, the module monitors the packet loss rate and signal strength changes of the Bluetooth / Wi-Fi connection in real time. When the packet loss rate exceeds 5% or the signal strength drops below -85dBm, the system automatically records the abnormal time points and generates fluctuation curves. The Wi-Fi 6E module supports simultaneous connection of up to 8 simulated terminal devices to test the protocol response capability of the car audio system in multi-device access scenarios, avoiding connection interruption issues caused by protocol conflicts.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Please see Figure 1-6An automated testing device for the durability of mechanical buttons in a car audio system includes a testing frame 1. A positioning rod 2 is fixedly connected to the upper end of the testing frame 1. A PLC controller 3 is fixedly connected to the outer wall of the positioning rod 2. An anti-slip pad 4 is adhered to the inner wall of the testing frame 1. Electric push rods 5 are installed on both sides of the testing frame 1. A support frame 6 is installed at one end of each electric push rod 5. A fixing rod 7 is fixedly connected to the inner wall of each support frame 6. A synchronous motor 8 is fixedly connected to the outer wall of each fixing rod 7. A contact rotor 9 is fixedly connected to one end of the synchronous motor 8. A lifting frame 10 abuts against the outer wall of the contact rotor 9. The frame 10 is movably connected to the testing frame 1, and the inner wall of the lifting frame 10 is slotted. The outer wall of the lifting frame 10 is abutted against a first spring 11. The inner wall of the lifting frame 10 is equipped with a guide rail 12. Both ends of the guide rail 12 abut against a second spring 13. One end of the second spring 13 abuts against a first tensioning frame 14. The guide rail 12 and the first tensioning frame 14 are engaged and connected. The first tensioning frame 14 is symmetrically arranged about the central axis of the guide rail 12. A first rubber block 15 is adhered to the outer wall of the first tensioning frame 14, and the outer wall of the first tensioning frame 14 and the outer wall of the first rubber block 15 are tightly fitted together. The first rubber block 15 is square in shape, and a first locking frame 16 is installed at one end of the first tightening frame 14. The first tightening frame 14 and the first locking frame 16 are movably connected, and the inner wall of the first tightening frame 14 is designed with openings. The guide rail 12 is used to move the first tightening frame 14. When it is necessary to adjust the position of the detection rod 17, the operator rotates the first locking frame 16 so that the narrower side faces the guide rail 12. The first tightening frame 14 is in a relaxed state, and the guide rail 12 can slide freely along the lifting frame 10. After the position is adjusted, the operator rotates clockwise or counterclockwise. Rotating the first locking bracket 16 clockwise causes its wider side to gradually approach and eventually contact the surface of the guide rail 12. Since the size of the wider side is larger than the initial gap, it will exert a squeezing force on the first tightening bracket 14, forcing the first rubber block 15 at one end of the first tightening bracket 14 to fit tightly against the surface of the lifting frame 10. The position of the first tightening bracket 14 is quickly locked by friction. This retains the flexible adjustment capability of the traditional guide rail 12 and solves the problem of quick fixation. It is suitable for frequent model change scenarios in the testing of various types of car audio buttons, effectively improving the operating efficiency and positioning stability of the equipment.

[0026] Please see Figure 1-6An automated testing device for the durability of mechanical buttons in a car audio system is disclosed. A testing rod 17 is mounted on the inner wall of a guide rail 12. A third spring 18 abuts against the outer wall of the testing rod 17. One end of the third spring 18 abuts against a second tensioning frame 19. A second rubber block 20 is adhered to the outer wall of the second tensioning frame 19. A second locking frame 21 is mounted on one end of the second tensioning frame 19. A laser light 22 is mounted on the upper end of the testing rod 17, and the testing rod 17 is engaged with the laser light 22. The inner wall of the testing rod 17 has an open design. A silicone button mold head 23 is mounted on the lower end of the testing rod 17. The outer wall of the testing rod 17 is tightly fitted to the inner wall of the silicone button mold head 23, and the outer wall of the testing rod 17 is straight. The diameter is smaller than the inner wall diameter of the silicone button mold head 23. A Bluetooth 5.3 connection module 24 is electrically connected to one side of the PLC controller 3, and a Wi-Fi 6E connection module 25 is electrically connected to one side of the Bluetooth 5.3 connection module 24. A detection rod 17 is used to engage and fix the laser lamp 22. The detection rod 17 serves as the mounting carrier and positioning actuator for the laser lamp 22. The detection rod 17 is made of high-strength, lightweight alloy material and is elongated. One end has a matching slot for the laser lamp 22. The operator only needs to insert the laser lamp 22 into the slot to complete the installation without additional tools. The hollow channel of the detection rod 17 is aligned with the beam emission of the laser lamp 22. The direction is completely coaxial, ensuring that the laser beam can be emitted from one end of the detection rod 17 without obstruction. When the laser lamp 22 is powered on, the beam is conducted to the front end of the detection rod 17 through the hollow channel, forming a visible green laser dot. During the positioning operation, the operator only needs to align the front end of the detection rod 17 with the car audio button panel and observe the overlap between the laser dot and the center point of the button for fine-tuning. If the laser dot deviates from the center of the button, push the detection rod 17 to slide along the guide rail 12 until the light spot completely covers the center of the button. At the same time, the Bluetooth 5.3 module supports BLE and BR / EDR dual modes and is compatible with previous versions of Bluetooth 5.0, 5.1, 5.2 and other protocols, which can simulate the interaction between the car audio system and mobile phones / cars. In pairing scenarios with Bluetooth devices, the Wi-Fi 6E module supports the 6GHz band and is backward compatible with Wi-Fi 5 and Wi-Fi 4 protocols. It can simulate wireless connections between car audio systems and smart home devices. During button durability testing, the module monitors the packet loss rate and signal strength changes of the Bluetooth / Wi-Fi connection in real time. When the packet loss rate exceeds 5% or the signal strength is below -85dBm, the system automatically records the abnormal time points and generates fluctuation curves. The Wi-Fi 6E module supports simultaneous connection of 8 simulated terminal devices to test the protocol response capability of the car audio system in multi-device access scenarios, avoiding connection interruption issues caused by protocol conflicts.
