[0002] In the research and development and production of automobiles, the power window regulator is a crucial component that requires rigorous performance testing, among which electromagnetic compatibility (EMC) testing is a key aspect. Applying precise and stable torque to the power window regulator during EMC testing is an important method for evaluating its performance in complex electromagnetic environments.

[0003] Existing torque testing devices have several drawbacks. First, their complex structure and cumbersome operation make them difficult to use.

Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0035] To address the issues of complex operation and poor versatility in existing torque testing devices, this application provides a torque testing device 100 for testing the torque of an automotive window regulator 1. Figure 1 This is a schematic diagram of the forward structure of the torque testing device provided in this embodiment. Figure 2 This is a top-down structural diagram of the torque testing device provided in this embodiment, as shown below. Figure 1 and Figure 2 As shown, the torque testing device 100 includes a fixed base 10, a clamping assembly 20, an adjusting bracket 30, and a damper 40.

[0036] The clamping assembly 20 includes an outer connector 21 and an inner connector 22 movably embedded in the outer connector 21. At least a portion of the inner connector 22 protrudes above the fixed base 10, and at least a portion of the outer connector 21 is located below the fixed base 10. The inner connector 22 is detachably connected to the motor drive shaft of the automotive window regulator 1.

[0037] The adjusting bracket 30 includes a support member 31 and an adjusting member 32. The support member 31 is disposed on the adjusting member 32. The car window regulator 1 is adjustablely connected to the support member 31 in the vertical direction. The adjusting member 32 is movably connected to the fixed base 10. The adjusting member 32 is used to adjust the distance between the support member 31 and the inner connecting member 22 in the horizontal direction.

[0038] The damper 40 is installed below the fixed base 10. The connecting end of the damper 40 is connected to the outer connector 21. The car window regulator 1 applies torque to the inner connector 22 and transmits the torque to the connecting end of the outer connector 21 and the damper 40 through the inner connector 22.

[0039] The torque testing device 100 of this application includes a fixed base 10, a clamping assembly 20, an adjusting bracket 30, and a damper 40. The support member 31 of the adjusting bracket 30 is adjustable horizontally from the adjusting member 32, and the automotive window regulator 1 is adjustable vertically from the support member 31. The motor drive shaft of the automotive window regulator 1 is detachably connected to the inner connecting member 22 of the clamping assembly 20. This enables the automotive window regulator 1 to be adjustable horizontally and vertically connected to the adjusting bracket 30 and the clamping assembly 20, thus allowing the adjusting bracket 30 and the clamping assembly 20 to accommodate automotive window regulators 1 of different sizes, thereby solving the problems of complex operation and poor versatility.

[0040] To make the technical solution, purpose and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0041] The torque testing device 100 of this application is used to test the torque of the automotive window regulator 1. Please refer to the following: Figure 2 The automotive window regulator 1 includes a transmission 1a and a motor 1b. The transmission 1a is triangular in shape and has at least one mounting hole on its surface. The transmission 1a also has a protruding drive shaft. The motor 1b is laterally mounted on one side of the transmission 1a. Exemplarily, the transmission 1a can be circular, square, or other shapes, and the motor 1b and transmission 1a can be connected in other ways. The automotive window regulator 1 may or may not include the transmission 1a; that is, the output shaft of the automotive window regulator 1 can be either the output shaft of the motor 1b or the output shaft of the transmission 1a, without limitation.

[0042] like Figure 1 and Figure 2As shown, the fixed base 10 is a square plate structure with a perforation in the center. The fixed base 10 is the working platform of the torque testing device 100. The square plate structure of the fixed base 10 facilitates the installation of the car window regulator 1 and other functional components, and can also ensure the structural stability of the torque testing device 100.

[0043] To facilitate the connection of other functional components mounted on the fixed base 10, the fixed base 10 is provided with connectors 11, which can be bolts. Multiple connectors 11 are bolted onto the fixed base 10 to connect other functional components.

[0044] During the torque test, the clamping of the automotive window regulator 1 needs to be convenient and stable. Therefore, the structure of the clamping assembly 20 can affect the clamping efficiency and test stability of the clamping process.

[0045] In some implementations, such as Figure 1 As shown, the clamping assembly 20 includes an outer connector 21 and an inner connector 22 movably embedded in the outer connector 21. At least a portion of the inner connector 22 protrudes above the fixed base 10, and at least a portion of the outer connector 21 is located below the fixed base 10. The inner connector 22 is detachably connected to the drive shaft of the automotive window regulator 1.

[0046] Specifically, the clamping assembly 20 includes an outer connector 21 and an inner connector 22 with a circular sleeve structure. The outer surface of the outer connector 21 has a radially protruding step at the bottom and a straight cylindrical shape at the top. The inner surface of the outer connector 21 is a cone shape that is larger at the top and smaller at the bottom. The outer surface of the inner connector 22 matches the inner surface of the outer connector 21, and the two can form a sliding fit structure.

[0047] The outer connector 21 and the inner connector 22 are perpendicularly inserted through the hole in the center of the fixed base 10 along the axial direction. The upper part of the inner connector 22 protrudes from the upper surface of the fixed base 10 to facilitate connection with the drive shaft of the car window regulator 1. The lower part of the inner connector 22 is movably connected to the step at the bottom of the outer connector 21, and the lower part of the inner connector 22 is located on the lower surface of the fixed base 10. The upper part of the outer connector 21 can move upward and protrude from the upper surface of the fixed base 10 to drive the inner connector 22.

[0048] The inner hole of the inner connector 22 can connect to the drive shaft of the automotive window regulator 1. A detachable connection, such as a snap-fit, screw-fit, or pin-fit, can be formed between the inner hole of the inner connector 22 and the drive shaft of the automotive window regulator 1. For example, the cross-section of the inner hole of the inner connector 22 is circular, or it can be hexagonal, etc., without limitation. The outer connector 21 and the inner connector 22 can also be mating square components, or they can be partially mating oblique components, without limitation.

[0049] In some implementations, such as Figure 1 As shown, the inner connector 22 is provided with at least two interlocking inner teeth 221. The outer connector 21 moves in the vertical direction and drives at least two of the inner teeth 221 to engage inward. The inner teeth 221 engage with the drive shaft of the car window regulator 1.

[0050] Specifically, the top of the inner hole of the inner connector 22 is provided with at least two, three, four, five, or other numbers of grooves along the axial direction. Two, three, four, five, or other numbers of internal teeth 221 are formed between the grooves, creating a multi-lobed and elastic structure at the top of the inner connector 22. Understandably, when the conical inner surface of the outer connector 21, which is fitted onto the inner connector 22, slides upward and abuts against the conical inner surface of the inner connector 22, at least two opposing internal teeth 221 engage inward, forming an elastic clamping structure that contracts under pressure and releases upon release, thus providing a clamping function. Furthermore, at least two internal teeth 221 engage inward to engage and clamp the drive shaft of the automotive window regulator 1.

[0051] For example, the clamping assembly 20 can be made of metal or non-metal, and the clamping assembly 20 can be a wedge snap, a cross pin snap, or other clamping connection structure, without limitation.

[0052] In some implementations, such as Figure 1 and Figure 2 As shown, in order to simplify the driving method and driving mechanism of the clamping assembly 20, the clamping assembly 20 also includes a collar 23 that is slidably connected to the outer connector 21. One side of the collar 23 is connected to the bottom of the fixed base 10 and drives the outer connector 21 to reciprocate in the vertical direction.

[0053] Specifically, the collar 23 is a circular sleeve structure with a central hole. The inner hole of the collar 23 is fitted onto the lower step of the outer connector 21. The inner hole of the collar 23 and the straight cylindrical part of the outer connector 21 are in clearance fit. The collar 23 can also move up and down along the outer connector 21 while being fitted onto it. For example, the collar 23 can be a metal or non-metal structural component. The collar 23 and the clamping assembly 20 can be connected by snap-fit, screw connection, or other methods. The collar 23 can be connected to a hydraulic drive structure, a pneumatic drive structure, or an electric drive structure, and there are no restrictions on this.

[0054] In some other embodiments, the other side of the collar 23 is provided with an outwardly protruding handle 231, which drives the collar 23 to swing back and forth and drives the outer connector 21 to move back and forth in the vertical direction.

[0055] Specifically, a handle 231 protruding outward is provided on one side of the outer surface of the collar 23. The handle 231 is connected to the collar 23 as an integral structure. Pulling or pressing the handle 231 can drive the outer connector 21 to move up and down.

[0056] In some other embodiments, a support column 24 extends downward from the perforated edge at the center of the fixed base 10 and adjacent to the lower surface of the inner connector 22. The support column 24 is movably connected to the collar 23. The handle 231 and the collar 23 swing about the support column 24 as the origin, driving the outer connector 21 to move. Understandably, one side of the upper part of the collar 23 has a movable connection position with the support column 24. Pressing the handle 231 drives the collar 23 to form a lever structure with the support column 24 as the fulcrum. The test operator can operate by pressing the handle 231 with one hand, which is more labor-saving and can also improve clamping efficiency.

[0057] In some other implementations, such as Figure 1 As shown, in order to facilitate the quick reset of the external connector 21 and simplify the reset structure, the clamping assembly 20 also includes an elastic element 25, the upper end of which abuts against the bottom end of the external connector 21.

[0058] Specifically, the elastic element 25 is a compression spring and is installed below the outer connector 21. Pressing the handle 231 causes the collar 23 to swing around the support column 24 as the origin, which in turn causes the outer connector 21 to move downward. During the downward movement of the outer connector 21, the elastic element 25 is compressed and contracts, and the internal teeth 221 of the inner connector 22 open outward and relax. Releasing the handle 231 causes the elastic element 25 to rebound and push the outer connector 21 upward, which in turn causes the internal teeth 221 of the inner connector 22 to engage and clamp inward.

[0059] For example, the elastic element 25 can also be a wave spring, a rubber pad or other elastic component. The elastic element 25 can also be sleeved on the outer connector 21 or connected to the outer connector 21 and the collar 23 in other ways. There are no restrictions here.

[0060] During torque testing, connecting the adjusting bracket 30 to the automotive window regulator 1 is usually a complex and time-consuming process. Therefore, improving the structure of the adjusting bracket 30 can enhance the convenience and efficiency of the test.

[0061] In some implementations, such as Figure 1 and Figure 2 As shown, in order to enable the adjustment bracket 30 to be adjustable in both the horizontal and vertical directions, the adjustment bracket 30 includes a support member 31 and an adjustment member 32. The support member 31 is disposed on the adjustment member 32. The car window regulator 1 is vertically adjustable and connected to the support member 31. The adjustment member 32 is movably connected to the fixed base 10. The adjustment member 32 is used to adjust the distance between the support member 31 and the inner connecting member 22 in the horizontal direction.

[0062] Specifically, the adjusting bracket 30 is used to connect to the mounting hole of the gearbox 1a of the car window regulator 1, and the support 31 and adjusting member 32 of the adjusting bracket 30 are both mounted on the upper surface of the fixed base 10.

[0063] Among them, the support member 31 is a columnar structural member, and the adjusting member 32 is a strip-shaped structural member. The support member 31 is installed on the adjusting member 32 to form an integral part. When a mounting hole of the transmission 1a is inserted through the support member 31, the transmission 1a can move up and down along the support member 31, so that the transmission 1a has space to move up and down relative to the fixed base 10. It can be understood that the support member 31 of the adjusting bracket 30 can be adapted to the insertion and connection of transmissions 1a of different thicknesses.

[0064] In some embodiments, the adjusting member 32 is provided with a groove structure or the fixed base 10 is provided with a groove structure, so that the adjusting member 32 and the fixed base 10 connected to each other can be displaced relative to each other in the horizontal direction. A slide rail or other structure may also be installed between the adjusting member 32 and the fixed base 10 so that they can be displaced relative to each other in the horizontal direction, which is not limited here.

[0065] During the process of adjusting the bracket 30 to connect the car window regulator 1, the drive shaft of the transmission 1a is engaged in at least two internal teeth 221 of the inner connecting member 22 of the clamping assembly 20. The engagement depth of the drive shaft of the transmission 1a in the internal teeth 221 can be adapted to the position of the mounting hole of the transmission 1a through which the support member 31 passes. Moreover, the engagement position of the drive shaft of the transmission 1a and the internal teeth 221 is fixed in the horizontal direction. The relative displacement between the adjusting member 32 and the support member 31 connected to it and the fixed base 10 allows the distance between the support member 31 and the inner connecting member 22 to be arbitrarily adjustable in the horizontal direction. This makes the torque testing device 100 of this application applicable to a wide range of car window regulators 1, and it is convenient to install and highly versatile.

[0066] In some implementations, such as Figure 2 As shown, at least two sets of the adjusting brackets 30 are spaced apart on the fixed base 10.

[0067] Specifically, when the transmission 1a of the automotive window regulator 1 has two or more mounting holes, in order to ensure that the automotive window regulator 1 is securely clamped, at least two sets of adjusting brackets 30 can be installed, and the distance between the two sets of adjusting brackets 30 can be adjusted according to the position of the mounting holes of the transmission 1a.

[0068] For some other implementations, please refer to [link / reference]. Figure 1 and Figure 2 The adjusting member 32 is provided with a sliding groove 321 extending in the horizontal direction, and the fixed base 10 is provided with a connecting member 11. The connecting member 11 passes through the sliding groove 321 and forms an adjustable connection with the sliding groove 321.

[0069] Specifically, the strip-shaped adjusting member 32 has a waist-shaped sliding groove 321 along its length. A connecting member 11 of the fixed base 10 is bolted through the sliding groove 321. The adjusting member 32 can swing or move horizontally within the sliding groove 321 with the connecting member 11 as the origin, so as to adjust the distance between the supporting member 31 and the inner connecting member 22, that is, to adapt to the distance between the drive shaft and the mounting hole of different automotive window regulators 1.

[0070] In order to improve the torque testing accuracy of the torque testing device 100 of this application, the torque testing device 100 includes a damper 40, the damper 40 is provided with an adjustable setting member 41 and a locking member 42, the setting member 41 is rotated to the torque value to be tested and the locking member 42 is locked.

[0071] Specifically, the damper 40 has a cylindrical body, the setting member 41 is annular, and the setting member 41 is movably mounted on the top of the damper 40. The locking member 42 is a clamping device mounted on the upper side of the damper 40. Rotating the setting member 41 can drive the anti-torsion device inside the damper 40. The damper 40 has at least 1 to 10 positions, including 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or other numbers of positions. According to the different testing requirements of the automotive window regulator 1, the setting member 41 is rotated to the corresponding position, and then the locking member 42 is tightened to hold the setting member 41 in place to lock the test position. This application uses a magnetic damper and sets multiple test positions, thus enabling more accurate verification of the torque of the automotive window regulator 1 and improving the torque testing accuracy of the automotive window regulator 1.

[0072] In some embodiments, the damper 40 is installed below the fixed base 10, and the connecting end of the damper 40 is connected to the external connector 21. The torque generated by the car window regulator 1 is transmitted to the damper 40 through the external connector 21. That is, the connecting end of the top of the damper 40 is connected to the step at the bottom of the external connector 21 of the clamping assembly 20, and an elastic member 25 is installed between the two. It can be understood that the elastic member 25 is located between the external connector 21 and the damper 40, and the two ends of the elastic member 25 abut against the step at the bottom of the external connector 21 and the connecting end of the damper 40, respectively, so that the elastic force direction of the elastic member 25 is consistent with the moving direction of the connecting end of the damper 40 and the external connector 21 of the clamping assembly 20, and the elastic force of the elastic member 25 can be concentrated on the bottom of the external connector 21.

[0073] In some implementations, please refer to [the relevant documentation]. Figure 1 and Figure 2 To ensure the structural stability of the torque testing device 100, the torque testing device 100 also includes a mounting plate 50 spaced apart from the fixed base 10. At least one side bracket 60 is connected between the mounting plate 50 and the fixed base 10 to form a frame, and the damper 40 is mounted on the mounting plate 50.

[0074] Specifically, the mounting plate 50 is a square plate structure and is spaced apart from the fixed base 10. At least one side bracket 60 is connected between the mounting plate 50 and the fixed base 10. The fixed base 10, the side bracket 60 and the mounting plate 50 form a frame structure, and the damper 40 is connected above the mounting plate 50. Thus, from top to bottom, a connection structure system is formed of the car window regulator 1, the adjusting bracket 30, the clamping assembly 20, the damper 40 and the mounting plate 50. This structure is compact and the processing and installation process is simple, which is conducive to use and maintenance.

[0075] For example, the side bracket 60 can be a vertical plate structure, a column structure, or a bolt. The fixed base 10 and the mounting plate 50 can be square, round, polygonal, or other shapes. The fixed base 10, the mounting plate 50, and the side bracket 60 can be made of metal materials such as steel and aluminum or non-metallic materials such as plastic and wood. The connection structure system of the car window regulator 1, the adjusting bracket 30, the clamping assembly 20, the damper 40, and the mounting plate 50 can be set vertically, tilted, or horizontally, and there are no restrictions here.

[0076] To control the start and stop of the automotive window regulator 1 and the testing time of the torque testing device 100, the torque testing device 100 further includes a control component connected to the automotive window regulator 1. Understandably, the torque testing device 100 has a control box, within which a control component controls the power supply and communication of the automotive window regulator 1.

[0077] During the testing process, the torque testing device 100 of this application first adjusts the setting member 41 of the damper 40 to the corresponding gear according to the torque test value of the tested car window regulator 1. Then, it tightens the locking member 42, places the car window regulator 1 to be tested on the fixed base 10, presses the handle 231 to drive the outer connecting member 21 of the collar 23 to move downward, and the inner teeth 221 of the inner connecting member 22 to loosen outward. The drive shaft of the transmission 1a of the car window regulator 1 is inserted into the inner teeth 221. Then, the position of the support member 31 on the adjusting bracket 30 is aligned with the mounting hole of the transmission 1a of the car window regulator 1. Then, the handle 231 is pressed down. 31. Loosen the internal gear 221, then insert the gearbox 1a mounting hole of the car window regulator 1 onto the support 31. Then, loosen the handle 231 to clamp the internal gear 221 and the drive shaft of the gearbox 1a that is engaged. Next, the control component is powered on to the motor 1b of the car window regulator 1. The motor 1b of the car window regulator 1 applies torque to the drive shaft of the gearbox 1a.
