Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

Therefore, it cannot be understood as a limitation on the present utility model.

[0035] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0037] After the mechanical strength life test of the existing battery pack, the residual torque test of the fastening bolts or nuts is required to determine whether the structural strength and initial torque are appropriate. The static measurement method is a common and direct residual torque measurement method. It obtains the residual torque by directly measuring the torque value after the rotating system stops rotating. The static measurement method mainly includes the torque sensor method and the cantilever beam method. The torque sensor method is to directly measure the residual torque by installing a torque sensor on the shaft of the rotating system. The torque sensor can be a sensor based on the principle of strain gauge, magnetostriction or capacitance. This method has high measurement accuracy and is suitable for various types of rotating systems. Cantilever beam method, this method indirectly infers the residual torque by fixing a cantilever beam on the rotating system and measuring the deflection of the cantilever beam. The deflection of the cantilever beam is proportional to the residual torque, and the deflection can be measured by a force sensor or an optical measuring instrument. This method is suitable for some rotating systems where the torque sensor cannot be directly installed. However, the current technology cannot accurately measure the residual torque of bolts or nuts. The results obtained by different torque wrenches, different equipment, and different people are very different, and the data results are unreliable.

[0038] Based on this, please refer to Figure 1 and Figure 2 The torque detection tool 1000 provided in the embodiment of the utility model can effectively improve the above-mentioned technical problems. The torque detection tool 1000 can measure the residual torque of the threaded fastener multiple times by changing the angle of the torque detection device 300 relative to the housing 100 to improve the accuracy of torque detection.

That is, the torque detection device 300 is in the plane where the surface of the housing 100 is located, and can rotate relative to the housing 100 by a certain angle.

[0040] When the torque detection device 300 is working, that is, when the torque detection device 300 is detecting the threaded fastener to be detected, such as a screw, a bolt, etc., the torque detection device 300 is locked on the housing 100, and the torque detection device 300 will not rotate relative to the housing 100. At this time, the torque detection device 300 detects the torque of the threaded fastener to be detected, and then feeds back to the analysis electronic component 200, and the analysis electronic component 200 obtains a torque value. After the torque detection device 300 completes the detection of the threaded fastener to be detected once, the operator loosens the torque detection device 300 relative to the housing 100, and the torque detection device 300 can rotate a certain angle relative to the housing 100 in the plane where the surface of the housing 100 is located. After the torque detection device 300 rotates a certain angle relative to the first position, the torque detection device 300 is locked to be fixed relative to the housing 100, and the torque detection device 300 is used again to perform torque detection on the same threaded fastener to be detected, and the analysis electronic component 200 obtains another torque value. Repeat the above operation multiple times to obtain multiple torque values, and obtain the torque detection analysis value after comparison and detection to improve the accuracy of residual torque detection.

In order to facilitate locking the torque detection device 300 when the torque detection device 300 is working so that it does not rotate relative to the housing 100, a driving roller 315 is connected to the snap-in roller 313 in this embodiment, and the operator achieves the locking and loosening of the torque detection device 300 by rotating the driving roller 315. In order to further facilitate the operator to rotate the driving roller 315, the snap-in roller 313 and the driving roller 315 in this embodiment are rotatably connected via an embedded roller 314. Rotating the driving roller 315 can drive the embedded roller 314 to rotate, thereby driving the snap-in roller 313 to rotate, so as to achieve the locking and loosening of the torque detection device 300 relative to the housing 100. Of course, in addition to using the clamping roller 313 and the driving roller 315 to achieve the locking and loosening of the torque detection device 300 relative to the housing 100, fasteners such as bolts or other methods can also be used, which are not limited here.

[0042] Please continue reading Figure 1 , Figure 2 , and combined with Figure 3The torque detection device 300 in this embodiment includes a first driving rod 310, and the first driving rod 310 includes a first rod member 311 and a torque detection sleeve 312.

The operator pulls the tightening band 323 to change the size of the connecting buckle 322. The connecting buckle 322 is used to bind to the threaded fastener to be tested. By changing the size of the connecting buckle 322, the tightening state of the detection piece for torque detection of the threaded fastener to be tested is changed, and then the same threaded fastener to be tested is subjected to multiple torque measurements when the detection piece is in different tightening states to obtain multiple torque measurement values, and then a more accurate measurement torque value is obtained after detection and analysis. The force and torque applied by the second rod 321 to the threaded fastener to be tested can be transmitted to the analysis electronic component 200 through the force, and the analysis electronic component 200 can obtain the corresponding measured torque value.

[0063] According to a torque detection tool 1000 provided in this embodiment, its working principle is as follows:

[0064] When the first driving rod 310 is working, that is, when the first driving rod 310 is detecting the threaded fastener to be tested, such as a screw, a bolt, etc., the first driving rod 310 is locked on the housing 100, and the first driving rod 310 will not rotate relative to the housing 100. At this time, the first driving rod 310 detects the torque of the threaded fastener to be tested, and then feeds back to the analysis electronic component 200, and the analysis electronic component 200 obtains a torque value. After the first driving rod 310 completes the detection of the threaded fastener to be tested once, the operator loosens the first driving rod 310 relative to the housing 100, and at this time, the torque detection device 300 can rotate a certain angle relative to the housing 100 on the plane where the surface of the housing 100 is located, and the rotation angle is measured by the angle measurement assembly 600.

Repeat the above operation multiple times to obtain multiple torque values, and obtain the torque detection analysis value after comparison and analysis to improve the accuracy of torque detection.

[0065] When the second drive rod 320 is working, the connection buckle 322 of the second drive rod 320 is used to cooperate with the threaded fastener to be tested to obtain the torque value of the threaded fastener to be tested. After one measurement, by adjusting the tightening strap 323 to change the size of the connection buckle 322, the torque test is performed on the same threaded fastener to be tested to obtain another test torque value. Repeat the above operation multiple times to obtain the test value of the torque of the same threaded fastener to be tested under different tightening states of the second drive rod 320. After comparing and analyzing multiple torque test values, a more accurate torque value is obtained, thereby improving the accuracy of torque detection.

[0066] In summary, the torque detection tool 1000 includes a housing 100, an analysis electronic component 200, and a torque detection device 300. The analysis electronic component 200 is disposed in the housing 100, and the torque detection device 300 is electrically connected to the analysis electronic component 200, thereby realizing torque detection of the threaded fastener. In addition, since the torque detection device 300 can be rotatably connected to the housing 100, multiple torques can be measured for the same threaded fastener to be tested at different angles of the torque detection device 300 relative to the housing 100. After comparing and analyzing the multiple torque values, a more accurate measurement torque value of the threaded fastener to be tested can be obtained, so as to improve the accuracy of residual torque detection.
