[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0039] like Figures 1 to 11 As shown, this application provides a vibration testing device for an in-vehicle central control PAD screen, used for vibration testing of automotive central control screens. The vibration testing device includes a vibration fixture 100, a driver bracket 300, a vibration table body 200, and a vibration control cabinet 400. The vibration fixture 100 is located at the upper end of the vibration table body 200, enabling the vibration table body 200 to provide a power source for the vibration testing process of the PAD screen 500 fixed on the vibration fixture 100. The driver bracket 300 is located inside the vibration table body 200, mainly used to hold the PAD driver 600 and to detach the PAD driver 600 from the vibration table body 200 to prevent unstable power supply from the PAD driver 600 to the PAD screen 500 due to vibration. The vibration control cabinet 400 is located on one side of the vibration table body 200 and is communicatively connected to the vibration table body 200, used to control the working mode of the vibration table body 200 to achieve data interaction with the vibration table body 200.
[0040] The PAD screen 500 refers to the central control screen of a car. With continuous technological innovation, central control screens have evolved from monochrome display panels to LCD screens, and now to large-size, multi-functional touchscreens, allowing control of almost all in-vehicle functions, including navigation, multimedia entertainment, vehicle status display, voice interaction, and remote control. However, central control screens also face many challenges, one of which is the decline in performance indicators caused by vibrations during high-speed driving. To address this, the vehicle-mounted central control PAD screen 500 vibration testing device proposed in this application can simulate vibration tests on the central control screen before installation in the vehicle to verify its stable operation under complex vibration environments, thereby reducing the occurrence of malfunctions. Furthermore, the vehicle-mounted central control PAD screen 500 vibration testing device proposed in this application can also effectively identify and intercept defective products during the production process, preventing defective products from leaving the factory.
[0041] In an optional embodiment, the vibration fixture 100 includes a fixture frame, a positioning bracket 103, and a detection module 104. The fixture frame has a base 101 and a support 102. The positioning bracket 103 and the detection module 104 are both disposed on the support 102, so that the PAD screen 500 can be mounted on the fixture frame through the positioning bracket 103, so that the detection module 104 can monitor the adverse conditions of the PAD screen 500 during vibration.
[0042] In an optional embodiment, the support 102 is inclinedly disposed on the base 101, which is disposed at the upper end of the vibration table body 200, to simulate the inclined installation and fixation of the PAD screen 500 in the vehicle loading state, thereby improving the test accuracy.
[0043] In an optional embodiment, the angle between the support 102 and the base 101 is between 100 and 110 degrees, specifically 105 degrees. This simulates the 15-degree tilt of the PAD screen 500 during vehicle installation, ensuring that the PAD screen 500 maintains the same posture as in actual vehicle installation throughout the vibration test. The detection module 104 is an RGB detection module that can monitor the PAD screen 500 in real time for defects such as black screen or flickering during vibration, effectively preventing defective products from being detected.
[0044] In an optional embodiment, the positioning bracket 103 is provided with a chuck structure 1031, and the chuck structure 1031 is provided with claws around its periphery so that the chuck structure 1031 can clamp the PAD screen 500 through the claws, thereby supporting and fixing the PAD screen 500, preventing the PAD screen 500 from falling during the test, and improving the test accuracy.
[0045] In an optional embodiment, the vibration fixture 100 includes a clamping module 105, which is disposed above the chuck structure 1031, and a detection module 104 is disposed below the chuck structure 1031. The clamping module 105 is used to clamp the PAD screen 500, which can effectively prevent the positioning failure of the PAD screen 500 due to vibration, and ensure that the PAD screen 500 maintains the same posture as the actual vehicle installation situation to complete the entire vibration test process.
[0046] In an optional embodiment, the clamping module 105 includes a drive member 1052, a clamping member 1051, and a fixing block 1053. The drive member 1052 is mounted on the support 102 via the fixing block 1053. The clamping member 1051 is connected to the drive member 1052 to fix the PAD screen 500 to the positioning bracket 103. This effectively prevents the positioning failure of the PAD screen 500 due to vibration and ensures that the PAD screen 500 maintains the same posture as in the actual vehicle installation to complete the entire vibration test process.
[0047] In an optional embodiment, the drive unit 1052 includes a quick clamp, which includes a handle, a clamping rod, and a clamp seat mounted on the support 102. The handle is rotatably mounted on the clamp seat, one end of the clamping rod is connected to the handle, and the other end of the clamping rod is connected to the clamping member 1051, which facilitates manual operation and switching. The user does not need to have strong mechanical expertise and can be used by any operator.
[0048] In an optional embodiment, the clamping member 1051 includes a jaw member 10511 and a jaw piece 10512. The jaw member 10511 is provided with a sliding groove structure, and the jaw piece 10512 is installed on the side of the jaw member 10511 facing away from the sliding groove structure. The sliding groove structure is slidably installed on the clamping seat, so that the jaw member 10511 can move along the length direction of the clamping seat.
[0049] In an optional embodiment, the support 102 includes an outer side plate 1021 and a support plate 1022. The outer side plate 1021 surrounds the outer side of the base 101, and the two ends of the support plate 1022 are respectively connected to the inner sidewalls of the two oppositely arranged outer side plates 1021 to improve the connection strength between the outer side plate 1021 and the base 101.
[0050] For example, the base 101 has a rectangular structure, and the outer side plate 1021 surrounds the six sides of the base 101 to increase the number of tests that the vibration testing device can perform on the PAD screen 500, so that the PAD screen 500 fixed on the six sides can be tested for vibration at the same time, effectively improving production capacity.
[0051] Specifically, each side is provided with at least one clamping module 105, at least one chuck structure 1031, and at least one detection module 104, so that each chuck structure 1031 can be used to position each PAD screen 500, each clamping module 105 can effectively prevent the positioning failure of the PAD screen 500 due to vibration, and each detection module 104 can monitor the corresponding PAD screen 500 in real time for black screen, flickering, and other defective states during the vibration process, effectively intercepting defective products, thereby realizing the simultaneous vibration test of at least six PAD screens 500, effectively improving production capacity.
[0052] In an alternative embodiment, the outer side plate 1021 is provided with a perforated structure to reduce the weight of the outer side plate 1021 and increase the frequency of vibration.
[0053] In an alternative embodiment, the angle between the outer side plate 1021 and the base 101 is between 100 and 110 degrees.
[0054] In one optional embodiment, the vibration table body 200 includes a vibration motor 204, a counterweight frame 202, and a vibration table surface 201 connected to the counterweight frame 202. The counterweight frame 202 has an accommodating cavity 2023. The vibration motor 204 is disposed on the vibration table surface 201 and housed in the accommodating cavity 2023. A vibration fixture 100 is mounted on the vibration table surface 201, and a driver bracket 300 is disposed inside the counterweight frame 202. The vibration motor 204 provides the power source for the entire vibration test. After the vibration fixture 100 is mounted on the vibration table surface 201, the vibration motor 204 drives the vibration table surface 201 and the vibration fixture 100 to vibrate vertically together in the Z-axis direction, and the amplitude and frequency are adjustable. The counterweight frame 202 not only increases the bottom configuration of the vibration table body 200, preventing the vibration table body 200 from being top-heavy, but also raises the vibration table surface 201 to a height suitable for human operation.
[0055] In an optional embodiment, the counterweight frame 202 includes a first frame 2021 and a second frame 2022, a accommodating cavity 2023 is formed in the first frame 2021, the first frame 2021 and the second frame 2022 are detachably connected, and the driver bracket 300 is disposed on the inner side of the second frame 2022.
[0056] In an optional embodiment, the vibration table body 200 further includes a damping component 203 disposed on the side of the second frame 2022 away from the first frame 2021 to reduce the resonance of the counterweight frame 202 to the ground.
[0057] In an optional embodiment, the driver support 300 includes a tray 301 and a support column 302. The support column 302 is located at the lower end of the tray 301 and is used to support the tray 301. The tray 301 is used to place the PAD driver 600 and to separate the PAD driver 600 from the vibration table body 200 to prevent unstable power supply caused by vibration.
[0058] In an optional embodiment, a plurality of partitions are spaced apart on the tray 301, and placement slots are formed between or between the partitions and the tray 301 for placing the PAD driver 600 to be tested.
[0059] In an optional embodiment, the vibration control cabinet 400 includes a control box 401, a display 403, a control unit 402, and a communication interface 404. The display 403 is located at the upper end of the control box 401, and the control unit 402 and the communication interface 404 are located on the control box 401. This allows the display 403 and the control unit 402 to be connected to the vibration table body 200 through the communication interface 404 to achieve motion control and data interaction. This not only makes control more convenient and adaptable, but also makes it easier for the operator to control the vibration frequency.
