Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0022] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0023] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] As living standards improve, people's demands for car functions are also increasing. Whether it's the multimedia entertainment needs of rear passengers during family trips or the need for video conferencing in cars during business activities, in-vehicle display devices are indispensable.
[0028] During the manufacturing process of the vehicle-mounted display device 20, it is necessary to inspect the dimensions of the vehicle-mounted display device 20 to ensure that the product is safe, reliable, and meets customer requirements. However, the traditional method for inspecting the dimensions of the vehicle-mounted display device 20 mainly involves using measuring tools (such as vernier calipers) to measure the dimensions of the vehicle-mounted display device 20. This requires operators to rely on experience for observation and judgment, which is both time-consuming and prone to errors.
[0029] In this regard, one embodiment of this application provides a dimensional inspection tool 10, which can be used in the automotive manufacturing field, for example, for dimensional inspection of in-vehicle equipment, specifically for inspecting whether the thickness of the in-vehicle display device 20 meets the standard. Of course, this dimensional inspection tool 10 can also be applied to fields such as machinery manufacturing and electronic manufacturing.
[0030] like Figure 1 As shown, the dimensional inspection tool 10 includes an inspection block 100. The inspection block 100 has a first surface 110, a second surface opposite to the first surface 110, and a third surface 120 located between the first surface 110 and the second surface. The third surface 120 is provided with an inspection groove 130, which penetrates the first surface 110 and the second surface.
[0031] During the manufacturing process of the vehicle-mounted display device 20, when it is necessary to inspect the thickness of the vehicle-mounted display device 20, first align the opening of the inspection slot 130 of the dimensional inspection tool 10 with the edge of the vehicle-mounted display device 20, then move the dimensional inspection tool 10 or the vehicle-mounted display device 20, and observe whether the edge of the vehicle-mounted display device 20 smoothly passes through the opening of the inspection slot 130 and enters the inspection slot 130. If it passes smoothly, the thickness of the vehicle-mounted display device 20 is deemed acceptable; otherwise, the thickness of the vehicle-mounted display device 20 is deemed unacceptable. It should be noted that... Figure 1 and Figure 2 The hollow arrow in the image represents the direction of movement.
[0032] It should be noted that before inspection, a dimensional inspection tool 10 of the corresponding size and specifications needs to be customized according to the specific size and shape requirements of the vehicle display device 20. The manufacturing process of the dimensional inspection tool 10 adopts advanced CNC machining technology to ensure the accuracy and fit of each component.
[0033] To ensure the long-term stability and accuracy of the dimensional inspection tool 10, regular calibration and maintenance are required. Calibration includes dimensional calibration and functional calibration to ensure that all indicators of the inspection tool meet design requirements. Maintenance includes routine maintenance measures such as cleaning, lubrication, and tightening, as well as necessary parts replacement and repair.
[0034] The dimensional inspection tool 10 is made of wear-resistant, corrosion-resistant, and high-precision engineering plastics or metals to ensure long-term stability and accuracy. Optionally, the dimensional inspection tool 10 can be made of phenolic plastic (i.e., bakelite) or metal. To ensure that the dimensional inspection tool 10 does not damage the vehicle display device 20 during inspection, the surface of the inspection block 100 can be covered with a protective layer. This protective layer can be made of Teflon, which has high-temperature resistance and can be applied to the surface of the inspection block 100 using adhesive bonding or other methods.
[0035] The dimensional inspection tool 10 for vehicle-mounted equipment of this application, by setting an inspection groove 130 on the inspection block 100, allows for the inspection of the thickness of the vehicle-mounted display device 20. This is achieved by observing whether the edge of the device smoothly passes through the opening of the inspection groove 130 and enters it. If it does, the thickness of the vehicle-mounted display device 20 is deemed acceptable. Therefore, this dimensional inspection tool 10 not only simplifies and speeds up the inspection method, eliminating the need for complex measuring equipment and specialized personnel, but also provides clear and intuitive results, making it easy for personnel to operate and understand. Furthermore, it improves inspection efficiency and significantly increases the yield and production capacity of the production line.
[0036] like Figure 1As shown, in some embodiments, there are two inspection slots 130, which are distributed on both sides of the central axis M of the inspection block 100. When inspecting the thickness of multiple vehicle display devices 20 with the same target size, the size inspection tool 10 can be placed between two adjacent vehicle display devices 20, and the opening of each inspection slot 130 can be aligned with the edge of the corresponding vehicle display device 20. Then, it can be observed at the same time whether the edge of each vehicle display device 20 can pass smoothly through the opening of the corresponding inspection slot 130 and enter the inspection slot 130. This can improve the inspection efficiency. In this case, the size specifications (including shape and size) of the two inspection slots 130 on the inspection block 100 are the same. Of course, the two inspection slots 130 on the inspection block 100 can also have different dimensions (e.g., the same shape, different dimensions, or both different shapes and dimensions). When inspecting the thickness of the target vehicle display device 20, the opening of the corresponding inspection slot 130 can be aligned with the edge of the target vehicle display device 20, and then it can be observed whether the edge of the target vehicle display device 20 can pass smoothly through the opening of the corresponding inspection slot 130 and enter the inspection slot 130. When inspecting the thickness of vehicle display devices 20 of other target sizes, the opening of the other inspection slot 130 can be aligned with the edge of the vehicle display device 20, and then it can be observed whether the edge of the target vehicle display device 20 can pass smoothly through the opening of the corresponding inspection slot 130 and enter the inspection slot 130. It is not necessary to use two size inspection tools 10 to inspect two vehicle display devices 20 of different sizes, which simplifies the structure of the size inspection tool 10.
[0037] The two inspection slots 130 may have the same shape, or the same shape and size, or different shapes and sizes, and can be set accordingly as needed.
[0038] Optionally, the two inspection slots 130 are symmetrically distributed on both sides of the central axis M of the inspection block 100. In this way, the thickness of vehicle-mounted display devices 20 of the same size and specifications can be effectively inspected on the production line.
[0039] like Figure 1 As shown, in some embodiments, the opening of the inspection slot 130 is provided with a first rounded corner 131. The first rounded corner 131 can prevent the opening of the inspection slot 130 from scratching the vehicle display device 20, thus protecting the vehicle display device 20.
[0040] like Figure 1 As shown, in some embodiments, the inspection slot 130 is a rectangular slot. This inspection block 100 can inspect the generally rectangular vehicle-mounted display device 20. The width H of the rectangular slot is equal to or slightly greater than the thickness H of the vehicle-mounted display device 20.
[0041] like Figure 2As shown, in some embodiments, the inspection block 100 also has opposing fourth surfaces 140 and fifth surfaces 150, with the first, second, and third surfaces located between the fourth surface 140 and the fifth surface 150; the inspection groove 130 includes a communicating first groove portion 132 and a second groove portion 133, the first groove portion 132 being close to the fourth surface 140, and the second groove portion 133 being close to the fifth surface 150. The openings of the first groove portion 132 and the second groove portion 133 are flush, and the bottom of the second groove portion 133 is close to the central axis M of the inspection block 100. This structure of the inspection block 100 allows for the inspection of an in-vehicle display device 20 with a thick base 20a protruding from its bottom, wherein the groove width H of the first groove portion 132 is equal to or slightly greater than the thickness h of the in-vehicle display device 20, and the groove width of the second groove portion 133 is equal to or slightly greater than the thickness of the base 20a.
[0042] Optionally, such as Figure 2 As shown, a second rounded corner 134 is provided between the first groove 132 and the second groove 133. The second rounded corner 134 can prevent the groove opening of the inspection groove 130 from scratching the vehicle display device 20, thus protecting the vehicle display device 20.
[0043] Optionally, such as Figure 2 As shown, the inspection groove 130 also includes a third groove 135 communicating with the second groove 133. The third groove 135 is closer to the fifth surface 150 than the second groove 133, and the bottom of the third groove 135 is flush with the bottom of the second groove 133. Thus, when the base 20a of the vehicle display device 20 has an irregular flat structure, i.e., the thickness of the outer edge is greater than the thickness of the inner edge, the third groove 135 can be used to accommodate the outer edge of the base 20a, wherein the width of the third groove 135 is equal to or slightly greater than the thickness of the outer edge of the base 20a.
[0044] In some embodiments of this application, multiple inspection blocks 100 are provided, each with a different size specification for the inspection slot 130, to inspect the dimensions of vehicle-mounted devices of different sizes. The corresponding inspection block 100 can be selected according to the size and shape of the target vehicle-mounted display device 20, ensuring that the size specification of the inspection slot 130 on the inspection block 100 is the same as that of the target vehicle-mounted display device 20. Then, the opening of the inspection slot 130 on the corresponding inspection block 100 is aligned with the edge of the target vehicle-mounted display device 20, and it is observed whether the edge of the target vehicle-mounted display device 20 can smoothly pass through the opening of the corresponding inspection slot 130 and enter the inspection slot 130. In this way, the application range of the size inspection tool 10 can be expanded, enabling the inspection of vehicle-mounted display devices 20 of different sizes.

[0047] The dimensional inspection tool 10, by setting an inspection groove 130 on the inspection block 100, allows for easy inspection of the thickness of the vehicle-mounted display device 20. This is achieved by observing whether the edge of the vehicle-mounted display device 20 smoothly passes through the opening of the inspection groove 130 and enters it.
