[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] refer to Figure 1-4 The present invention provides a car navigation panel inspection fixture for testing various performance aspects of a car navigation panel. According to one embodiment, it includes a base 1, two opposing fixed plates 2, clamping devices 3 respectively fixed to the two fixed plates 2, a testing device 4, and a control device 5. The base 1, the two opposing fixed plates 2, and the clamping devices 3 are all in the same horizontal state (ideal state). This is because if the clamping devices 3 apply unbalanced or torsional forces to the car navigation panel during testing, the fixture may be damaged. Therefore, the installed base 1, the two opposing fixed plates 2, and the clamping devices 3 respectively fixed to the two fixed plates 2 need to be in the same horizontal state (ideal state).

[0030] In specific embodiments, such as Figure 1 As shown, the two opposing fixed plates 2 are L-shaped with a space in the middle. Since the sizes of car navigation panels vary, the distance between the two fixed plates 2 is fixed. Therefore, the clamping device 3 needs to be equipped with an adjustable size device. Specifically, the clamping device 3 includes grippers, which are symmetrically arranged on both sides of the car navigation panel 6 to fix the car navigation panel 6. The device that drives the grippers to clamp and release is a cylinder 32. For the accuracy of the detection, the two cylinders 32 are set horizontally, that is, the piston 323 extends and retracts horizontally to drive the grippers to clamp and release. However, the extension and retraction of the piston 323 only produces the clamping and releasing effect of the grippers, that is, the clamping position remains unchanged and it cannot clamp different sizes of car navigation panels.

[0031] Therefore, connecting blocks 81 are set at both ends of the two cylinders 32 away from the car navigation panel. Sleeves 82 are set on the connecting blocks 81. The sleeves 82 are connected to the horizontal linear driving component. The driving component is two symmetrically arranged telescopic components connected to the clamping device 3. The two telescopic components, such as linear motors, gears, racks, screws and other mechanical transmission devices, convert the rotational motion into linear motion. In order to connect with the control system to realize automation, electric push rods 7 are used in this embodiment. The use of servo motors can realize automated and accurate distance control. The two electric push rods 7 are fixed on the two fixed plates 2.

[0032] Furthermore, in order to achieve stability of distance adjustment, a linear slide groove 322 is provided on the fixed plate 2, and a sliding component is provided at the bottom of the cylinder 32 accordingly. The sliding component cooperates with the linear slide groove 322, thereby pushing the two electric push rods 7 to make the cylinder 32 slide, thereby adjusting the distance between the gripper and the car navigation panel 6.

[0033] Furthermore, the sliding component is a slider 321, of which there are two, arranged in parallel, such as... Figure 2 The system is configured such that a linear groove 322 adapted to the slide bar 321 is opened on the fixed plate 2, thereby the two electric push rods 7 push the cylinder 32 to slide through the cooperation of the slide bar 321 and the linear groove 322, thereby adjusting the distance between the gripper and the car navigation panel 6.

[0034] Furthermore, to prevent the slider 321 from sliding out, stops 324 are provided at both ends of the straight slide groove 322 to prevent it from sliding out.

[0035] Furthermore, to ensure the stability of the inspection of the car navigation panel, the electric push rod 7 is fixed on the fixing plate 2, and the sleeve 82 is then connected to the piston rod 71 of the electric push rod 7 with screws.

[0036] Of course, in order to ensure smooth sliding of the sliding parts, a structure similar to pulley 325 can be adopted, with four pulleys placed on both sides.

[0037] In some specific implementation methods, such as Figure 1 As shown, there are two clamping devices 3. Each clamping device 3 includes an upper clamping device 31 and a lower clamping device 33, which are opposite to each other. The upper clamping device 31 and the lower clamping device 33 are respectively connected to the piston 323 of the cylinder 32.

[0038] Furthermore, the upper clamping device 31 includes an upper top plate 311 and an upper jaw 312 mounted on the upper top plate 311, and the lower clamping device 33 includes a lower top plate 331 and a lower jaw 332 mounted on the lower top plate 331. The upper top plate 311 and the lower top plate 331 are respectively connected to the piston 323 of the cylinder 32, and the cylinder 32 is connected to the PLC 51 circuit of the control device. The piston 323 drives the upper top plate 311 and the lower top plate 331 to clamp and release the upper jaw 312 and the lower jaw 332.

[0039] In some specific implementation methods, such as Figure 1 As shown, the detection device 4 includes a detection element 41 located above the car navigation panel 6, which is used to detect the car navigation panel 6; the control device 5 includes a PLC 51, which is connected to a power supply; the PLC 51 is signal-connected to the detection element 41, and the PLC 51 is also connected to the clamping device 3 via wiring.

[0040] Specifically, the detection component 41 includes a bracket 411 mounted on two fixed plates 2. A screw 413 is connected to the middle of the bracket 411 by a nut 412. A connecting plate 414 is provided at the bottom of the screw 413. Multiple detection rods 415 are provided on the bottom surface of the connecting plate 414. Photoelectric sensors 4151 for detecting the car navigation panel 6 are provided on the multiple detection rods 415. The photoelectric sensors 4151 are connected to the PLC 51 circuit.

[0041] Working principle of photoelectric sensor 4151 in car navigation panel inspection fixture:

[0042] Photoelectric sensor 4151 component: This component consists of a transmitter and a receiver (the transmitter and receiver are prior art and are not shown in the figure). Only the principle is explained. The transmitter is responsible for emitting light beams, which are usually from semiconductor light sources, such as light-emitting diodes (LEDs) or laser diodes. The light beams are focused by a lens or reflector and then illuminate the navigation panel. The receiver is responsible for receiving the light signals reflected or scattered back by the panel and converting them into electrical signals.

[0043] Signal processing circuit: Located after the receiver, this circuit is responsible for processing the electrical signals converted by the receiver. Through amplification, filtering, and other operations, it extracts the useful signals and converts them into data that can be used for measurement.

[0044] Control and Display Unit: This unit is responsible for receiving data output from the signal processing circuit and performing further processing and analysis. Based on preset measurement standards, it determines whether the navigator panel is qualified and displays the results on the screen.

[0045] When the light beam emitted by the transmitter shines onto the navigation panel, part of the beam is reflected or scattered back by the panel. The receiver receives these reflected or scattered light signals and converts them into electrical signals. The signal processing circuit processes these electrical signals to obtain data that can be used for measurement. The control unit uses this data to determine the accuracy and quality of the navigation panel and displays the results.

[0046] The photoelectric sensor 4151 is mainly used to detect light-related data and parameters to ensure the normal operation of the navigation panel 6's display, touch, and environmental perception functions. Specifically, the photoelectric sensor 4151 detects the following data:

[0047] 1. Light Intensity: Detect the backlight intensity or ambient light intensity of the navigator panel 6 to ensure the visibility and clarity of the display screen under different lighting conditions.

[0048] 2. Luminous flux: Measure the light energy emitted by the navigator panel 6 to assess its brightness and uniformity.

[0049] 3. Light wavelength: Analyze the wavelength distribution of the light emitted by the navigator panel 6 to ensure its color accuracy and color gamut coverage.

[0050] 4. Touch light signal: The photoelectric sensor 4151 captures the changes in light signals generated by touch operation to detect the touch position and action.

[0051] 5. Touch response speed: The immediacy and accuracy of touch operation are evaluated by combining the response time and data processing speed of the photoelectric sensor 4151.

[0052] 6. Ambient light change: The photoelectric sensor 4151 monitors changes in external ambient light to adjust the brightness and contrast of the navigator panel 6, thereby improving the user's visual experience.

[0053] 7. Proximity Detection: In some advanced navigation panels, photoelectric sensor 4151 may be used to detect the proximity of the user's hand or an object to enable a smarter interactive experience.

[0054] The photoelectric sensor 4151 is used to detect light-related data and parameters to ensure that the display, touch and environmental perception functions of the navigator panel are normal.
