[0042] As mentioned in the background technology above, in order to improve the sun protection performance of vehicles with glass sunroofs, most vehicles with glass sunroofs are usually equipped with shading sunshade curtains. The sunshade curtains can block sunlight to reduce or avoid direct sunlight to the user's face, head, etc., which can effectively improve the user experience.
[0043] During the installation process of sunshade curtains, if the curtains are too large, they can collapse, become wavy, or wrinkle, affecting their proper function. On the other hand, if the curtains are too small, they cannot be assembled and will be scrapped. Therefore, during the curtain production process, strict requirements are placed on the curtain dimensions. Currently, curtains are typically cut manually using a steel ruler to measure and cut the dimensions.
[0044] However, during the measurement process, it is difficult to ensure that the steel ruler effectively fits the cord, which reduces the measurement accuracy of the cord and thus affects the overall dimensional accuracy of the cord.
[0045] To address the aforementioned issues, the present invention provides a testing device that provides a first and second perpendicular, intersecting scale line on a testing platform. Multiple reference lines and positioning blocks are located within one of the scale lines. The positioning blocks can locate the edge of the cord, effectively improving the alignment between the cord edge and the start of the scale lines and contributing to improved cord measurement accuracy. The reference lines enable workers to quickly and accurately read data from the scale lines, enabling the testing platform to quickly and accurately measure the length and width of the cord, thereby effectively improving the accuracy and efficiency of cord width and length measurements.
[0046] The following is a detailed description of the detection equipment provided in the embodiments of the present application in conjunction with the accompanying drawings.
[0047] Figure 1 A schematic diagram of the structure of a detection device provided in an embodiment of the present application is shown. Figure 2 A schematic diagram of the structure of a scale grid provided in an embodiment of the present application is shown in FIG. Figure 3 This is an enlarged view of a scale grid provided in an embodiment of the present application.
[0048] An embodiment of the present application provides a detection device that can be used to detect a curtain covering a vehicle, for example, the size of the curtain.
[0049] See also Figure 1 As shown, the detection device 100 may include a detection platform 110. For example, the detection device 100 may further include a detection base, and the detection platform 110 may be installed on the detection base 160. Figure 2 As shown, a scale grid 120 may be provided on the detection platform 110 . For example, the scale grid 120 may be distributed on the detection platform 110 by painting, engraving, or the like.
[0050] The scale grid 120 may include first scale lines 121 and second scale lines 122 that are perpendicular to and intersect each other. For example, the first scale lines 121 may be arranged along a first direction (i.e., the x-direction in the figure), and the second scale lines 122 may be arranged along a second direction (i.e., the y-direction in the figure). The first direction may be perpendicular to the second direction. The first scale lines 121 may be used to measure the size of the fabric 200 in the first direction, and the second scale lines 122 may be used to measure the size of the fabric 200 in the second direction.
[0051] For example, see Figure 1 As shown, during the measurement of the curtain fabric 200, the curtain fabric 200 can be laid on the testing platform 110, and one edge of the curtain fabric 200 can be aligned with the starting point of the first scale line 121. For example, the edge of the curtain fabric 200 in the width direction can be aligned with the starting point of the first scale line 121. The other edge can be aligned with the starting point of the second scale line 122. For example, the edge of the curtain fabric 200 in the length direction can be aligned with the starting point of the second scale line 122. In this case, the first scale line 121 can measure the dimension of the curtain fabric 200 in the first direction (i.e., the width), and the second scale line 122 can measure the dimension of the curtain fabric 200 in the second direction (i.e., the length), thereby measuring the width and length of the curtain fabric 200.
[0052] At least one of the first scale line 121 and the second scale line 122 may include multiple reference lines (e.g., first reference line 1211, second reference line 1212, third reference line 1213, etc.), and the multiple reference lines may divide the corresponding scale line into multiple scale lengths. For example, the first scale line 121 may include multiple reference lines, or the second scale line 122 may include multiple reference lines, or, in some examples, both the first scale line 121 and the second scale line 122 may include multiple reference lines.
[0053] Taking the first scale line 121 including multiple reference lines as an example, the multiple reference lines can divide the first scale line 121 into multiple scale lengths, which can facilitate the staff to read the scale value, so that the staff can quickly and accurately read the size of the curtain 200 in the first direction, thereby effectively improving the measurement accuracy and measurement efficiency of the curtain 200 in the first direction.
[0054] In order to improve the accuracy of the size (i.e., length) of the curtain 200 in the second direction, the curtain 200 can be rotated 90° so that the edge of the curtain 200 in the length direction is aligned with the starting point of the first scale line 121, so that the first scale line 121 can accurately measure the length direction of the curtain 200, thereby improving the measurement accuracy and efficiency of the length direction of the curtain 200.
[0055] The detection device 100 may further include a positioning block 130, which is connected to the detection platform 110 and is located at the beginning of at least one of the first scale line 121 and the second scale line 122. For example, the positioning block 130 may be located at the beginning of the first scale line 121, or the positioning block 130 may be located at the beginning of the second scale line 122, or the positioning block 130 may be set at the beginning of both the first scale line 121 and the second scale line 122.
[0056] The positioning block 130 can limit the curtain 200 to reduce or avoid movement or displacement of the curtain 200, which helps to improve the alignment between the edge of the curtain 200 and the edge of the scale line (the first scale line 121 or the second scale line 122), thereby improving the accuracy of measuring the curtain 200.
[0057] In the embodiment of the present application, a first scale line 121 and a second scale line 122 are provided on the detection platform 110, and multiple reference lines and positioning blocks 130 are provided on one of the scale lines. The positioning blocks 130 can locate the edge of the curtain 200, effectively improving the alignment between the edge of the curtain 200 and the starting position of the scale lines, thereby helping to improve the measurement accuracy of the curtain 200. The reference lines enable workers to quickly and accurately read the data on the scale lines, allowing the detection platform 110 to quickly and accurately measure the length and width of the curtain 200, thereby effectively improving the measurement accuracy and efficiency of the width and length of the curtain 200.
[0058] Continue to see Figure 2 As shown, the first scale lines 121 can be arranged along the width of the testing platform 110, and the second scale lines 122 can be arranged along the length of the testing platform 110. This ensures that the width and length of the scale grid 120 correspond to the width and length of the testing platform 110, which helps to improve the rationality of the layout of the scale grid 120 on the testing platform 110 and enhance the utilization rate of the testing platform 110. It also makes it easier for staff to read the values and improves the operability of the testing device 100.
[0059] Continue to see Figure 2 As shown, in the embodiment of the present application, the first scale line 121 may include multiple reference lines, and the positioning block 130 may be located at the starting point of the first scale line 121. In this way, the positioning block 130 can position the curtain 200 at the starting point of the first scale line 121, which can effectively improve the alignment between the edge of the curtain 200 and the starting point of the first scale line 121, and can effectively improve the measurement accuracy of the curtain 200 in the first direction.
[0060] The multiple reference lines can divide the first scale line 121 into multiple scale lengths, which can facilitate reading by staff, effectively improve the accuracy of reading the curtain 200 on the first scale line 121, and enhance the reading efficiency of the curtain 200 on the first scale line 121.
[0061] See also Figure 2 and Figure 3 As shown, the reference lines may include a first reference line 1211 and a second reference line 1212. The ratio of the scale length of the first reference line 1211 to the scale length of the second reference line 1212 may be 5:1. That is, the ratio of the distance between two adjacent first reference lines 1211 to the distance between two adjacent second reference lines 1212 is 5:1. For example, the scale length of the first scale line 121 may be 500 mm, and the scale length of the second reference line 1212 may be 100 mm.
[0062] The first reference line 1211 can be used to locate the size of the curtain 200 within a larger range, while the second reference line 1212 can be used to locate the size within a smaller range than the first reference line 1211. For example, if the length of the curtain 200 is 577 mm, the first reference line 1211 can facilitate the operator to quickly locate the size to 500 mm, while the second reference line 1212 can quickly locate the reading within 100 mm based on 500 mm, allowing the operator to locate the size of the curtain 200 between greater than 500 mm and less than 600 mm for further reading.
[0063] Continue to see Figure 2 and Figure 3 As shown, the reference line also includes a third reference line 1213. The ratio of the scale length of the second reference line 1212 to the scale length of the third reference line 1213 can be 2:1. That is, the ratio of the distance between two adjacent second reference lines 1212 to the distance between two adjacent third reference lines 1213 is 2:1. For example, if the scale length of the second reference line 1212 is 100 mm, the scale length of the third reference line 1213 can be 50 mm.
[0064] This allows the third reference line 1213 to be positioned and read within a range smaller than the second reference line 1212. For example, continuing with the example of a curtain 200 having a length of 577 mm, when the first reference line 1211 and the second reference line 1212 are used to locate the length of the curtain 200 between 500 mm and 600 mm, the third reference line 1213 can be used to quickly locate the length of the curtain 200 between 550 mm and 600 mm, thereby further narrowing the range for reading the length of the curtain 200.
[0065] Continue to see Figure 2 and Figure 3As shown, the reference lines also include a fourth reference line 1214. The ratio of the scale length of the third reference line 1213 to the scale length of the fourth reference line 1214 is 5:2. That is, the ratio of the distance between two adjacent third reference lines 1213 to the distance between two adjacent fourth reference lines 1214 is 5:2. For example, if the scale length of the third reference line 1213 is 50 mm, the scale length of the fourth reference line 1214 can be 20 mm.
[0066] This allows the fourth reference line 1214 to be positioned and read within a range smaller than the third reference line 1213. For example, continuing with the example of a 577 mm length of the curtain 200, if the first reference line 1211, the second reference line 1212, and the third reference line 1213 determine the length of the curtain 200 to be between 550 mm and 600 mm, the fourth reference line 1214 can further narrow the reading range of the curtain 200's size. For example, the fourth reference line 1214 can quickly determine the length of the curtain 200 to be between 570 and 600 mm, thereby further narrowing the reading range of the curtain 200's size and improving the measurement accuracy of the curtain 200.
[0067] Continue to see Figure 2 and Figure 3 As shown, the reference lines also include a fifth reference line 1215, and the ratio of the scale length of the fourth reference line 1214 to the scale length of the fifth reference line 1215 is 2:1. That is, the ratio of the distance between two adjacent fourth reference lines 1214 to the distance between two adjacent fifth reference lines 1215 is 2:1. For example, if the scale length of the fourth reference line 1214 is 20 mm, the scale length of the fifth reference line 1215 can be 10 mm.
[0068] This allows the fifth reference line 1215 to be positioned and read within a range smaller than the fourth reference line 1214. For example, continuing with the example of a fabric 200 length of 577 mm, if the first reference line 1211, the second reference line 1212, the third reference line 1213, and the fourth reference line 1214 determine the fabric 200 size to be between 570 mm and 600 mm, the fifth reference line 1215 can further narrow the range of readings for the fabric 200 size. For example, the fourth reference line 1214 can quickly determine the fabric 200 size to be between 570 mm and 580 mm, effectively narrowing the range of readings for the fabric 200 size, ensuring a reading error of less than or equal to 5 mm, and effectively improving the measurement accuracy of the fabric 200.
[0069] Continue to see Figure 2 and Figure 3As shown, the reference lines also include a sixth reference line 1216, and the ratio of the scale length of the fifth reference line 1215 to the scale length of the sixth reference line 1216 is 2:1. That is, the ratio of the distance between two adjacent fifth reference lines 1215 to the distance between two adjacent sixth reference lines 1216 is 2:1. For example, if the scale length of the fifth reference line 1215 is 10 mm, the scale length of the fifth reference line 1215 can be 5 mm.
[0070] This allows the sixth reference line 1216 to be positioned and read within a range smaller than the fifth reference line 1215. For example, if the length of the curtain 200 is 577 mm, and the first, second, third, fourth, and fifth reference lines 1211, 1212, 1213, 1214, and 1215 are used to locate the length of the curtain 200 between 570 mm and 580 mm, the sixth reference line 1216 can be used to further narrow the range of readings for the curtain 200. This allows the curtain 200 to be quickly located between 575 and 580 mm. At this point, the operator can, based on experience, locate the curtain 200 at approximately 577 mm to complete the measurement. This reduces the reading error for the curtain 200 to less than 5 mm, effectively reducing the reading error and thus improving the measurement accuracy of the curtain 200.
[0071] Figure 4 A cross-sectional view of a detection device 100 provided in an embodiment of the present application is shown in FIG. Figure 5 This is a cross-sectional view of a detection device 100 provided in an embodiment of the present application under another cross-section.
[0072] Continue to see Figure 4 and Figure 5 As shown, the positioning block 130 may include a positioning portion 131 and a connecting portion 132 connected to each other. The connecting portion 132 may be connected to the detection platform 110. The positioning portion 131 may be connected to the detection platform 110 via the connecting portion 132. In addition, the positioning portion 131 may be perpendicular to the surface of the detection platform 110. For example, the connecting portion 132 may be connected to the detection platform 110 by bonding, clamping, snapping, or bolt fasteners 140.
[0073] For example, in an embodiment of the present application, the connecting portion 132 can be connected to the detection platform 110 via a bolt fastener 140, which can effectively improve the firmness and reliability of the connection between the connecting portion 132 and the detection platform 110, and help improve the reliability and stability of the positioning block 130 set on the detection platform 110, thereby effectively improving the overall structural stability of the detection equipment 100.
[0074] For example, the positioning block 130 may further include a positioning pin 150, and the connecting portion 132 and the detection platform 110 may have positioning holes that cooperate with the positioning pin 150. Before the connecting portion 132 and the detection platform 110 are connected via the bolt fasteners 140, the positioning pin 150 may be inserted into the positioning holes on the connecting portion 132 and the detection platform 110. This pre-positions the connecting portion 132 and the detection platform 110, thereby reducing or preventing misalignment of the bolt fasteners 140 between the connecting portion 132 and the detection platform 110 during the connection process, thereby affecting the connection of the bolt fasteners 140. This facilitates the installation of the bolt fasteners 140 and improves the assembly efficiency between the connecting portion 132 and the detection platform 110.
[0075] Continue to see Figure 5 As shown, there can be two positioning blocks 130 , and the two positioning blocks 130 can be arranged side by side at the starting point of the first scale line 121 . This can improve the positioning accuracy of the positioning blocks 130 on the edge of the curtain 200 , which helps to improve the measurement accuracy of the curtain 200 .
