[0033] It should be noted that in the relevant technology, GB 15741-1995 "Automobile and trailer license plate (frame) and its location" has relevant requirements for the shape, size, location and strength of the license plate (frame). At present, the installation inclination and visual range of the license plate (frame) are generally measured by multiple devices such as tape measure, digital angle ruler, level meter, etc., which is complicated to measure and has low measurement efficiency.

[0034] Based on this, the embodiment of the present application proposes a vehicle license plate plate detection device 1, wherein the first plate body 10 can be assembled with the vehicle license plate plate of the vehicle, and the first plate body 10 can be connected to the vehicle license plate plate by means of clamping, bolting, etc. The size and shape of the first plate body 10 can be the same as the size and shape of the vehicle license plate, and the assembly of the first plate body 10 with the vehicle license plate plate can simulate the effect of the assembly of the vehicle license plate with the vehicle license plate plate, thereby achieving the effect of the vehicle license plate plate detection device 1 detecting the installation tilt angle and the visual range of the vehicle license plate plate.

[0035] Along the first direction, the second plate body 20 and the third plate body 30 are located on the same side of the first plate body 10. Figure 1 When setting the direction, the first direction is Figure 1 Y direction in the diagram. When the vehicle license plate detection device 1 is assembled with the vehicle license plate, the second plate body 20 and the third plate body 30 are both located on the side of the first plate body 10 that is away from the vehicle license plate. Any two of the first plate body 10, the second plate body 20 and the third plate body 30 can be fixedly connected, and any two of the first plate body 10, the second plate body 20 and the third plate body 30 can be fixedly connected by welding or the like, and the relative positions of any two of the first plate body 10, the second plate body 20 and the third plate body 30 are fixed, so that the relative positions of the first plate body 10, the second plate body 20 and the third plate body 30 will not change, which is beneficial to improving the reliability and test accuracy of the vehicle license plate detection device 1.

[0036] Along the second direction, at least one side of the first plate body 10 is provided with a second plate body 20. Figure 1 When setting the direction, the second direction is Figure 1 The second direction is the X direction in the diagram. When the vehicle license plate is installed on the vehicle and the vehicle license plate detection device 1 is assembled with the vehicle license plate, the second direction is the width direction of the vehicle. Along the second direction, the first plate body 10 may be provided with a second plate body 20 on one side, or the first plate body 10 may be provided with a second plate body 20 on both sides. The embodiment of the present application is described by taking the first plate body 10 provided with a second plate body 20 on one side along the second direction as an example. When the vehicle license plate detection device 1 is assembled with the vehicle license plate, the second plate body 20 may be provided on the right side of the first plate body 10. Along the third direction, a third plate body 30 is provided on at least one side of the first plate body 10. When the vehicle license plate detection device 1 is as Figure 1When setting the direction, the third direction is Figure 1 Z direction in the diagram. Along the third direction, the first plate body 10 may be provided with a third plate body 30 on one side, or the first plate body 10 may be provided with a third plate body 30 on both sides. The present application takes the case where the first plate body 10 is provided with a third plate body 30 on one side along the third direction as an example for explanation. When the vehicle license plate detection device 1 is assembled with the vehicle license plate, the third plate body 30 may be provided below the first plate body 10. The first direction, the second direction and the third direction are perpendicular to each other. The first plate body 10, the second plate body 20 and the third plate body 30 may all be constructed as a plate body structure with a rectangular cross-section, and the first plate body 10, the second plate body 20 and the third plate body 30 are perpendicular to each other.

[0037] The second plate 20 can be used to detect the installation tilt angle of the vehicle license plate. The second plate 20 is formed with a first angle scale 21 in an arc shape. The first angle scale 21 can be arranged on the side of the second plate 20 away from the first plate 10 along the second direction. The first angle scale 21 can be constructed as a circular arc structure with a shape of 1 / 4 circle. The first angle scale 21 can be located between two adjacent sides of the second plate 20. The first angle scale 21 can extend from one side of the second plate 20 to the other side adjacent thereto. The two adjacent sides of the second plate 20 are perpendicular to each other. The scale line range of the first angle scale 21 can be 0°-90°. The second plate 20 is provided with a horizontal ruler 40 corresponding to the first angle scale 21. The horizontal ruler 40 can be movably connected to the second plate 20. The horizontal ruler 40 can move relative to the second plate 20 along the extension direction of the first angle scale 21. The horizontal ruler 40 can detect the installation tilt angle of the vehicle license plate by cooperating with the first angle scale 21.

[0038] The third plate 30 can be used to detect the visible range of both sides of the vehicle license plate along the second direction. The third plate 30 is formed with a second arc-shaped angle scale 31. The second angle scale 31 can be constructed as an arc-shaped structure with a shape of 1 / 4 circle. The second angle scale 31 can be located between two adjacent sides of the third plate 30. The second angle scale 31 can extend from one side of the third plate 30 to the other side adjacent thereto. The two adjacent sides of the third plate 30 are perpendicular to each other. The scale line range of the second angle scale 31 can be 0°-90°. The third plate 30 is provided with a first rotating scale 32 corresponding to the second angle scale 31. Along the third direction, the first rotating scale 32 can be located on the same side of the third plate 30 as the second angle scale 31. As an example, the first rotating scale 32 and the second angle scale 31 can be both located above the third plate 30, so as to facilitate reading data when measuring the visible range of the vehicle license plate.

[0039] The first rotating scale 32 can rotate around a first axis, the first axis is parallel to the third direction, and the first axis can be set at the center of the arc-shaped second angle scale portion 31, so as to achieve the effect that the first rotating scale 32 is rotatably set on the third plate body 30. As an example, the first rotating scale 32 can be formed with a first through hole, and the third plate body 30 can be formed with a first threaded hole. The first rotating scale 32 can be rotatably connected to the third plate body 30 through a first bolt 50. The first bolt 50 can be passed through the first through hole and assembled with the first threaded hole. The first bolt 50 is screwed with the third plate body 30. The first rotating scale 32 can rotate around the screw rod of the first bolt 50. The head of the first bolt 50 can abut against the first rotating scale 32, which can prevent the first rotating scale 32 from falling off the third plate body 30, which is conducive to achieving the effect that the first rotating scale 32 is rotatably set on the third plate body 30. The first rotating ruler 32 can rotate toward the outside of the third plate body 30. It should be noted that when the first rotating ruler 32 rotates in a direction away from the first plate body 10, the first rotating ruler 32 can rotate toward the outside of the third plate body 30. The first rotating ruler 32 can abut against obstacles outside the third plate body 30, and the first visible angle of the vehicle license plate along the width direction of the vehicle can be detected by rotating the first rotating ruler 32 toward the outside of the third plate body 30.

[0040] The vehicle license plate detection device 1 can simultaneously detect the installation tilt angle and visual range of the vehicle license plate, with a simple detection method and high detection efficiency. The vehicle license plate detection device 1 can be applied to detect the installation tilt angle and visual range of all vehicle license plates, with high versatility and strong practicality.

[0041] As an example, Figure 1As shown, the 0° scale line of the first angle scale portion 21 can be set on the edge where the second plate 20 is adjacent to the first plate 10, and the 90° scale line of the first angle scale portion 21 can be set on the edge of the second plate 20 away from the third plate 30 along the third direction, and the scale lines of the first angle scale portion 21 extend upward along an arc. When the moving level 40 detects the installation tilt angle of the vehicle license plate, the complementary angle of the angle read on the first angle scale portion 21 is the installation tilt angle of the vehicle license plate. As an example, the 0° scale line of the second angle scale portion 31 can be set on the edge where the third plate 30 is adjacent to the first plate 10, and the 90° scale line of the second angle scale portion 31 can be set on the edge of the third plate 30 along the second direction. There may be two second angle scale portions 31, and the two second angle scale portions 31 are arranged along the second direction, so that the vehicle license plate detection device 1 can detect the visible angles on both sides of the vehicle license plate along the second direction (i.e., the width direction of the vehicle). When the first rotating ruler 32 is rotated to measure the first visible angle of the vehicle license plate, the degree read on the second angle scale portion 31 is the first visible angle of the vehicle license plate along the width direction of the vehicle.

[0042] In some embodiments of the present invention, Figure 1 As shown, the second plate body 20 is further formed with a first arc-shaped hole 22 , which is adjacent to the first angle scale portion 21 and is arranged around the first angle scale portion 21 , and the level 40 is installed in the first arc-shaped hole 22 .

[0043] The second plate body 20 is also formed with a first arc-shaped hole 22, which can be constructed as an arc-shaped structure with a shape of 1 / 4 circle, and the shape of the first arc-shaped hole 22 can be the same as the shape of the first angle scale portion 21. Along the radial direction of the first arc-shaped hole 22, the first arc-shaped hole 22 can be adjacent to the first angle scale portion 21, the first arc-shaped hole 22 can be arranged around the first angle scale portion 21, and the first arc-shaped hole 22 can be arranged outside the first angle scale portion 21. The level 40 can be passed through the first arc-shaped hole 22, the level 40 can be limitedly abutted against the inner wall of the first arc-shaped hole 22, the level 40 can move along the extension direction of the first arc-shaped hole 22, and the level 40 can cooperate with the first angle scale portion 21, so as to achieve the effect of detecting the installation tilt angle of the vehicle license plate.

[0044] In some embodiments of the present invention, Figure 4-Figure 6As shown, the level ruler 40 may include: a mounting portion 41 and a detection ruler portion 42, the mounting portion 41 may include: a first mounting plate 411, a second mounting plate 412 and a connecting column 413, along the second direction, the first mounting plate 411 and the second mounting plate 412 are respectively located on both sides of the second plate body 20, the first mounting plate 411 and the scale lines of the first angle scale portion 21 are located on the same side of the second plate body 20, the detection ruler portion 42 is fixed to the first mounting plate 411, and the connecting column 413 is penetrated through the first mounting plate 411, the second mounting plate 412 and the first arc-shaped hole 22 to fix the first mounting plate 411 and the second mounting plate 412.

[0045] The level ruler 40 can be assembled with the first arc-shaped hole 22 through the mounting portion 41, and the detection ruler portion 42 can be matched with the first angle scale portion 21, so as to detect the installation tilt angle of the vehicle license plate. The mounting portion 41 can include a first mounting plate 411, a second mounting plate 412 and a connecting column 413. Along the second direction, the first mounting plate 411 and the second mounting plate 412 can be respectively located on both sides of the second plate body 20. The connecting column 413 is penetrated through the first mounting plate 411, the second mounting plate 412 and the first arc-shaped hole 22. The connecting column 413 can be fixedly connected to the first mounting plate 411 by means of clamping, bonding, etc., and the connecting column 413 can be fixedly connected to the second mounting plate 412 by means of clamping, bonding, etc. The first mounting plate 411 and the second mounting plate 412 can both abut against the second plate body 20, and the second plate body 20 is sandwiched between the first mounting plate 411 and the second mounting plate 412. The connecting column 413 can abut against the inner wall of the first arc-shaped hole 22, so that the connecting column 413 can only move along the extension direction of the first arc-shaped hole 22, which is conducive to improving the stability of the level ruler 40 moving in the first arc-shaped hole 22. The first mounting plate 411 and the first angle scale portion 21 are located on the same side of the second plate body 20, and the detection ruler portion 42 is arranged on the first mounting plate 411. The detection ruler portion 42 can be fixed to the first mounting plate 411 by means of clamping, bonding, etc. The detection ruler portion 42 can cooperate with the first angle scale portion 21 to achieve the effect of detecting the installation tilt angle of the vehicle license plate.

[0046] As an example, the detection ruler part 42 can be set as a level ruler. The detection ruler part 42 can use the principle of liquid level to detect the installation tilt angle of the vehicle license plate. The detection ruler part 42 can be constructed as a transparent tube filled with liquid. When the detection ruler part 42 moves relative to the second plate body 20 along the extension direction of the first angle scale part 21, the liquid level in the detection ruler part 42 can always remain parallel to the horizontal plane. When the vehicle license plate detection device 1 is assembled with the vehicle license plate, one of the scale lines of the first angle scale part 21 is parallel to the horizontal plane. When the horizontal liquid surface in the detection ruler part 42 is aligned with the scale line, the installation tilt angle of the vehicle license plate can be measured by reading the degree corresponding to the scale line. According to the specific arrangement of the starting position and extension direction of the scale lines in the first angle scale part 21, the read angle or the complementary angle of the read angle can be the installation tilt angle of the vehicle license plate.

[0047] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the second plate body 20 is also provided with a second rotating ruler 23 corresponding to the first angle scale portion 21, the scale lines of the second rotating ruler 23 and the first angle scale portion 21 are located on the same side of the second plate body 20, the second rotating ruler 23 is rotatably provided on the second plate body 20 around a second axis, the second axis is parallel to the second direction, and the second rotating ruler 23 is rotated toward the top of the second plate body 20 to detect a second visible angle of the vehicle license plate in the upward direction.

[0048] The second rotating scale 23 is arranged corresponding to the first angle scale 21. Along the second direction, the second rotating scale 23 and the first angle scale 21 are located on the same side of the second plate 20. Along the radial direction of the arc-shaped first angle scale 21, the second rotating scale 23 can be arranged on the side of the first angle scale 21 away from the first arc-shaped hole 22. The second rotating scale 23 and the horizontal scale 40 are respectively arranged on both sides of the first angle scale 21, which is conducive to avoiding the second rotating scale 23 and the horizontal scale 40 from colliding when moving. The second rotating scale 23 can be used in conjunction with the first angle scale 21. The second rotating scale 23 can rotate around the second axis, the second axis is parallel to the second direction, and the second axis can be arranged at the center of the arc-shaped first angle scale 21, so that the second rotating scale 23 can be rotatably arranged on the second plate 20. The second rotating ruler 23 can rotate toward the top of the second plate body 20 (i.e., away from the third plate body 30). By rotating the second rotating ruler 23 toward the top of the second plate body 20, the second rotating ruler 23 cooperates with the first angle scale part 21 to detect the second visible angle of the vehicle license plate in the upward direction.

[0049] As an example, the second rotating scale 23 can be formed with a second through hole, and the second plate body 20 can be formed with a second threaded hole. The second rotating scale 23 can be rotatably connected to the second plate body 20 through a second bolt 60. The second bolt 60 can be inserted into the second through hole and assembled with the second threaded hole. The second bolt 60 is screwed to the second plate body 20. The second rotating scale 23 can rotate around the screw rod of the second bolt 60. The head of the second bolt 60 can abut against the second rotating scale 23, which can prevent the second rotating scale 23 from falling off the second plate body 20, which is conducive to achieving the effect that the second rotating scale 23 is rotatably set on the second plate body 20.

[0050] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the second plate body 20 is also formed with a second arc-shaped hole 24, the second arc-shaped hole 24 is adjacent to the first angle scale portion 21, and the first angle scale portion 21 is arranged around the second arc-shaped hole 24, and the surface of the second rotating ruler 23 facing the second plate body 20 is provided with a first guide column 231, at least a portion of the first guide column 231 is installed in the second arc-shaped hole 24, and the first guide column 231 abuts against the inner wall of the second arc-shaped hole 24.

[0051] The second arc-shaped hole 24 can be constructed as an arc-shaped structure with a shape of 1 / 4 circle, and the shape of the second arc-shaped hole 24 can be the same as the shape of the first angle scale portion 21. Along the radial direction of the second arc-shaped hole 24, the second arc-shaped hole 24 can be adjacent to the first angle scale portion 21, and the first angle scale portion 21 is arranged around the second arc-shaped hole 24.

The first guide column 231 can be assembled with the second arc-shaped hole 24. At least a portion of the first guide column 231 is passed through the second arc-shaped hole 24.
