Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0048] like Figures 1-10 As shown, a device for measuring the attack angle of a car wiper includes a scale plate 2, a measuring platform 1, a gear connecting plate 3 and a gear pointer 4;

[0049] The scale plate 2 includes a first vertical plate 21, a bottom plate 22, and a second vertical plate 23 connected as an integral body. The first vertical plate 21 and the second vertical plate 23 are respectively arranged at two ends of the bottom plate 22. The second vertical plate 23 is provided with a circular scale plate 231.

[0050] The measuring platform 1 is located above the bottom plate 22 and both ends of the measuring platform 1 are rotatably mounted on the first vertical plate 21 and the second vertical plate 23;

[0051] The gear connecting plate 3 includes a connecting end and a first gear tooth 31. The gear connecting plate 3 is mounted on the measuring platform 1 through the connecting end and can rotate synchronously with the measuring platform 1.

[0052] The gear pointer 4 includes a pointer 41 and a second gear tooth 42. The gear pointer 4 is rotatably mounted at the center of the circular scale 231. The pointer 41 points to the scale of the circular scale 231. The second gear tooth 42 is engaged with the first gear tooth 31.

[0053] The measuring platform 1 rotates and drives the gear connecting plate 3 to rotate synchronously. The first gear teeth 31 of the gear connecting plate 3 engage with the second gear teeth 42 of the gear pointer 4 to transmit the gear, so that the pointer 41 swings in the circular dial 231 on the scale plate 2.

[0054] In some embodiments, as Figure 5 As shown, a scale 222 is provided at the bottom of the base plate 22, which can conveniently check the correct angle value of the car wiper; a supporting structure is provided at the bottom of the base plate 22, and the supporting structure includes a support leg 221 located at one end of the base plate 22 and two support legs 221 located at the other end of the base plate 22. The support structure of the three support legs 221 improves the stability of placement on the curved surface of the curved windshield and ensures the accuracy of measurement.

[0055] In some embodiments, as Figure 2 、 Figure 3As shown, the connecting end of the gear connecting plate 3 includes two connecting legs 32 at the lower end. The measuring platform 1 is provided with insertion holes 13 that cooperate with the connecting legs 32. The connecting legs 32 are inserted into the insertion holes 13, thereby connecting the gear connecting plate 3 to the measuring platform 1 through insertion. This also facilitates adjusting the meshing smoothness between the second gear teeth 42 and the first gear teeth 31. Of course, the gear connecting plate 3 and the measuring platform 1 can also be designed as an integrated structure.

[0056] In some embodiments, as Figure 3 As shown, the bottom of the measuring platform 1 is provided with protruding rotating portions 11 at both ends, each with a rotation hole. A recessed portion mates with the rotating portion 11 on the bottom plate 22. Connecting holes 24 are formed in the first and second vertical plates 21, 23 at either end of the recessed portion. These holes are connected by a rotating shaft. When a wiper is mounted on the measuring platform 1, the rotating shaft allows the measuring platform 1 to rotate on the scale plate 2. The scale indicated by the gear pointer 4 indicates the wiper's deflection angle.

[0057] In some embodiments, in order to better improve the rotational sensitivity of the measuring platform 1 on the scale plate 2 , bearings are installed in the connecting holes 24 on the first vertical plate 21 and the second vertical plate 23 .

[0058] In some embodiments, as Figure 2 As shown, the gear connecting plate 3 is provided with a sector-shaped end, on which the first gear teeth 31 are mounted. The gear pointer 4 is provided with a circular end, on which the second gear teeth 42 are mounted. The transmission ratio between the first gear teeth 31 and the second gear teeth 42 is 1:(2-12). For example, if the gear on which the first gear teeth 31 and the gear on which the second gear teeth 42 are mounted have a gear ratio of 8:1, the rotation angle of the first gear teeth 31 can be magnified 8 times and indicated on the circular scale 231 by the second gear teeth 42, resulting in a clearer display and more accurate measurement results.

[0059] In some embodiments, as Figure 1 、 Figure 2 As shown, the center of the circular end of the gear pointer 4 is coaxially arranged with the center of the circular scale 231, ensuring the concentricity of the gear pointer 4 and the circular scale 231. Then, a rotating shaft is installed in the center of the circular end and the center of the circular scale 231. By relying on the rotating shaft, the gear pointer 4 can be rotated relative to the circular scale 231. The pointer 41 on the gear pointer 4 swings synchronously in the circular scale 231 and points to different scale lines, so that the offset angle of the wiper can be obtained.

[0060] The rotating shaft can be fixedly connected or rotationally connected to the circular scale plate 231, and the gear pointer 4 rotates on the rotating shaft. In order to improve the sensitivity of rotation, a bearing can be installed on the gear pointer 4 to rotationally connect the rotating shaft to the bearing on the gear pointer 4.

[0061] In some embodiments, as Figure 3 As shown, the measuring platform 1 is provided with a mounting hole 12, which can be used to connect U-shaped interfaces of different lengths (such as Figure 11 (a) shows a 9 mm width wiper, such as Wuling, Foton and other models, the mounting hole 12 can also be used to install the connecting block 5, and various models of wipers can be connected by relying on the connecting block 5.

[0062] In some embodiments, as Figure 7-10 As shown, it also includes a connecting block 5 that is detachably mounted on the measuring platform 1. The connecting block 5 is integrated and is used to connect wipers of different models, thereby improving the application range of the automobile wiper attack angle measuring device of the present invention.

[0063] In some embodiments, as Figure 7-10 As shown, the connecting block 5 includes a first plate 51, a second plate 52, a third plate 53, a fourth plate 54 and a fifth plate 55. The second plate 52, the third plate 53 and the fifth plate 55 are connected in sequence and their bottoms are horizontal. The fourth plate 54 is installed on the third plate 53.

[0064] The first plate 51 is installed below the second plate 52 and the third plate 53. The first plate 51 is connected to the mounting hole 12 on the measuring platform 1. The first plate 51 can be inserted into the mounting hole 12 for easy assembly and disassembly.

[0065] The second plate 52 is provided with a special-shaped groove 521 and a bolt hole 522. The special-shaped groove 521 is used to match the connection with the B12 tank type interface (such as Figure 11 (e) shows a wiper, such as the Mercedes-Benz EQ and other models, the wiper is installed in the special-shaped groove 521 and the wiper is pressed and fixed after the bolt passes through the bolt hole 522. At this time, the installation method of the connecting block 5 on the measuring platform 1 is as follows Figure 8 As shown;

[0066] The third plate 53 is provided with a U-shaped groove 531, and both sides of the third plate 53 are provided with an L-shaped hole and a C-shaped hole 532, the L-shaped hole and the C-shaped hole 532 are connected, and the two fourth plates 54 are mounted on the L-shaped holes of the third plate 53 opposite to each other. The upper mounting surface 541 of the fourth plate 54 is used to mount the B1 interface (such as Figure 11 (i)) of the wiper, such as GL8 and other models, the lower mounting surface 542 is used to install the B2 interface (such as Figure 11(h) shown) of the wiper, such as the Land Rover Range Rover and other models; the H interface wiper is stuck on the top of the third plate 53; the C side plug interface (such as Figure 11 (d) The wiper is installed on the C-shaped hole 532, such as Volkswagen, Passat, 14 Mercedes-Benz E and other models;

[0067] The two fifth plates 55 are symmetrically mounted on the sides of the third plate 53. A mounting gap 552 is provided between the two fifth plates 55 for mounting an old-style 11 mm wide U-shaped interface wiper. A U-shaped hole 551 is provided on the fifth plate 55 for mounting a B13 interface wiper. The outer sides of the two fifth plates 55 are used to mount a B5 interface (such as Figure 11 (f) Wiper, such as the Volvo S90. Connecting block 5 allows direct connection to a variety of wiper models with different interface types, eliminating the need for frequent replacement. The integrated design of connecting block 5 offers high versatility and is less likely to be lost, improving ease of use.

[0068] When using, if the interface of the wiper is a B12 tank type interface, connect the connecting block 5 according to Figure 8 As shown, it is installed on the measuring platform 1; when the wiper is a non-B12 tank type interface, connect the connecting block 5 according to Figure 7 As shown, it is installed on the measuring platform 1;

[0069] Then the interface of the wiper is connected to the connecting block 5 accordingly. Through the rotational offset of the connecting block 5, the measuring platform 1 and the gear connecting plate 3, the offset angle is finally obtained by the scale line indicated by the pointer 41 on the circular scale 231 combined with the scale meter 222.

[0070] The automobile wiper attack angle measuring device of the present invention relies on the transmission cooperation of the gear connecting plate and the gear pointer to amplify the gear transmission ratio to amplify the automobile wiper offset angle to be detected, thereby ensuring that when measuring smaller offset angles, the measurement readings are faster and the results are more accurate.
