[0016] A method for detecting a pointer of an automobile electronic instrument, using the instrument panel pointer detection device to detect the pointer, comprises the following steps:

[0017] S1. First, the personnel place the instrument to be tested on the support plate, and then control the motor 1 to operate. When the motor 1 operates, it will drive the bevel gear 1 to rotate. At the same time, the bevel gear 2 will drive the transmission rod to rotate under the action of the bevel gear 1. At the same time, the worms on both sides will also rotate accordingly, and the worm wheel will also rotate under the action of the worm. At this time, the rotating rod will drive the upper half gear to rotate, and at the same time, the upper half gear will drive the lower half gear to rotate, so that the two rotating rods rotate at the same time, thereby driving the folding rod to extend. As the half gears rotate, the clamps will be driven to approach each other, so that the clamps clamp the instrument.

[0018] S2. After that, the height of the adjustment plate can be adjusted by the cylinder. When the card plate is inserted into the bottom end of the card plate, the motor three can be controlled to rotate. At this time, when the motor three rotates, it will drive the screw two to rotate. When the screw rotates, it will drive the tooth plate to rotate. The tooth plate will drive the gear three to rotate. When the gear three rotates, it will drive the card plate to rotate, so that the card plate limits the pointer, which is convenient for the subsequent tension detection of the pointer.

[0019] S3. After that, the motor 2 can be controlled to rotate. The motor 2 will drive the gear 2 to rotate through the gear 1. As the gear 2 rotates, the screw 1 will be driven to rotate, so that the screw pulls the top plate at the bottom, so that the tension of the pointer at the bottom is detected through the tension detector. The tension can be adjusted more finely through the gear 2 and the screw 1, thereby improving the accuracy of the detection data.

[0020] Beneficial effects of the present invention:

[0021] 1. The present invention extends the folding rod on the clamping mechanism. As the half gear rotates, the clamping plates are driven to approach each other to clamp and fix the instrument. At the same time, the rubber pad and the spring can change with the shape of the instrument, thereby improving the stability of the instrument during detection and preventing looseness from affecting the detection data.

[0022] 2. The present invention controls the rotation of motor 2, which drives gear 2 to rotate through gear 1. As gear 2 rotates, screw 1 rotates, so that the screw pulls the top plate at the bottom, and the tension detector detects the tension of the pointer at the bottom. The tension can be adjusted more finely through gear 2 and screw 1, thereby improving the accuracy of the detection data;

[0023] 3. The height of the adjustment plate is adjusted by the cylinder of the present invention. When the card plate is inserted into the bottom end of the card plate, the motor three can be controlled to rotate. At this time, when the motor three rotates, it will drive the screw rod two to rotate. When the screw rod rotates, it will drive the tooth plate to rotate. The tooth plate will drive the gear three to rotate. When the gear three rotates, it will drive the card plate to rotate, so that the card plate limits the pointer, which is convenient for the subsequent tension detection of the pointer. At the same time, limiting the position by the rotation of the card plate can be more convenient for personnel to operate and is also faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Control motor 2 1302 to rotate, motor 2 1302 will drive gear 2 1305 to rotate through gear 1 1304, and as gear 2 1305 rotates, screw 1 1 306 will be driven to rotate, so that the screw pulls the top plate 1401 at the bottom, so that the tension of the pointer at the bottom is detected through the tension detector 1402, and the tension can be adjusted more finely through gear 2 1305 and screw 1 1306, thereby improving the accuracy of the detection data.

[0042] like Figure 4 , Figure 5 and Figure 7 As shown, the detection mechanism 14 includes a top plate 1401, a tension detector 1402, a bottom shell 1403, a gear 3 1404, a tooth plate 1405, a screw 2 1406, a motor 3 1407 and a clamping plate 1408.

[0044] Here’s how it works:

[0045] After placing the instrument to be tested on the support plate 6, the motor 17 can be controlled to operate. When the motor 17 is operating, it will drive the bevel gear 18 to rotate.

As the half gear 1104 rotates, the clamping plates 1106 will be driven to approach each other, so that the clamping plates 1106 clamp the instrument and fix it. Thereafter, the height of the adjusting plate 1301 can be adjusted by the cylinder 12. When the clamping plate 1408 is inserted into the bottom end of the clamping plate 1408, , the motor three 1407 can be controlled to rotate. At this time, when the motor three 1407 rotates, it will drive the screw two 1406 to rotate, and when the screw rotates, it will drive the tooth plate 1405 to rotate, and the tooth plate 1405 will drive the gear three 1404 to rotate. When the gear three 1404 rotates, it will drive the card plate 1408 to rotate, so that the card plate 1408 limits the pointer, thereby facilitating the subsequent tension detection of the pointer, and thereafter the motor two 1302 can be controlled to rotate. The motor two 1302 will drive the gear two 1305 to rotate through the gear one 1304. As the gear two 1305 rotates, it will drive the screw one 1306 to rotate, so that the screw pulls the top plate 1401 at the bottom, so that the tension detector 1402 performs tension detection on the pointer at the bottom, and the tension can be adjusted more finely through the gear two 1305 and the screw one 1306, thereby improving the accuracy of the detection data.

10. A method for detecting a pointer of an automobile electronic instrument, using the automobile electronic instrument pointer detection device as claimed in any one of claims 1 to 9 to detect the pointer, characterized in that: The following steps are involved: S1. First, after placing the instrument to be tested on the support plate (6), the personnel can control the motor 1 (7) to operate. When the motor 1 (7) operates, it will drive the bevel gear 1 (8) to rotate. At the same time, the bevel gear 2 (9) will drive the transmission rod (10) to rotate under the action of the bevel gear 1 (8). At the same time, the worm gears (1101) on both sides will also rotate accordingly. The worm wheel (1102) will also rotate under the action of the worm gear (1101). At this time, the rotating rod (1103) will drive the upper half gear (1104) to rotate. At the same time, the upper half gear (1104) will drive the lower half gear (1104) to rotate, so that the two rotating rods (1103) rotate at the same time, thereby driving the folding rod (1105) to extend. As the half gear (1104) rotates, the clamping plates (1106) will be driven to approach each other, so that the clamping plates (1106) clamp and fix the instrument; S2. After that, the height of the adjustment plate (1301) can be adjusted by the cylinder (12). When the card plate (1408) is inserted into the bottom of the card plate (1408), the motor three (1407) can be controlled to rotate. At this time, when the motor three (1407) rotates, it will drive the screw rod two (1406) to rotate. When the screw rod rotates, it will drive the tooth plate (1405) to rotate. Then, the tooth plate (1405) will drive the gear three (1404) to rotate. When the gear three (1404) rotates, it will drive the card plate (1408) to rotate, so that the card plate (1408) limits the pointer, thereby facilitating the subsequent tensile force detection of the pointer. S3. After that, the motor 2 (1302) can be controlled to rotate. The motor 2 (1302) will drive the gear 2 (1305) to rotate through the gear 1 (1304). As the gear 2 (1305) rotates, the screw 1 (1306) will be driven to rotate, so that the screw pulls the top plate (1401) at the bottom, so that the tension of the pointer at the bottom is detected through the tension detector (1402). The tension can be adjusted more finely through the gear 2 (1305) and the screw 1 (1306), thereby improving the accuracy of the detection data.
