Description

Technical Field

[0001] The utility model relates to the technical field of test benches, in particular to a test bench for a torsion bar turnover mechanism. Background Art

[0002] In the related art, the cabs of most trucks adopt a torsion bar flipping type. During the process of the cab falling back, the torsion bar will generate a certain torque, and the cab will tilt to one side under the action of the torque, resulting in uneven gaps between the bumper, front panel and door.

[0003] The current solution typically involves adding a pre-bias to the tilt mechanism's mounting bracket. However, due to the non-rigid nature of the cab, determining the pre-bias value is difficult, necessitating multiple replacements of the tilt mechanism assembly to verify the value. Replacing the tilt mechanism assembly requires not only removing some exterior trim and disconnecting the oil, electrical, and air lines connecting the cab to the chassis, but also hoisting the cab. This complicates the tilt mechanism replacement process (a single tilt mechanism replacement is estimated to take 4-6 hours), resulting in a prohibitively high time cost for determining the pre-bias value, severely impacting vehicle production efficiency.

[0040] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0041] Reference below Figure 1-Figure 5 A test bench 100 for a torsion bar flipping mechanism 200 according to an embodiment of the present invention is described. The test bench 100 is used to confirm a pre-bias value of the torsion bar flipping mechanism 200 .

[0042] like Figure 1-Figure 5 As shown, the test bench 100 for the torsion bar flipping mechanism 200 according to the present invention includes: a first mounting seat 1 and an adjustment seat 3, the adjustment seat 3 is movably arranged on the first mounting seat 1; the adjustment seat 3 has a first mounting portion 31, the first mounting portion 31 is suitable for being assembled with the torsion bar flipping mechanism 200, the first mounting seat 1 defines an installation space 11, at least part of the adjustment seat 3 is arranged in the installation space 11, the first mounting seat 1 has a first avoidance hole 12, the first avoidance hole 12 corresponds to the first mounting portion 31 and extends along the moving direction of the adjustment seat 3.

[0043] The adjustment seat 3 is provided on the first mounting seat 1, and the adjustment seat 3 is movable relative to the first mounting seat 1. In some embodiments of the present application, one of the adjustment seat 3 and the first mounting seat 1 may have a slide groove 14, and the other of the adjustment seat 3 and the first mounting seat 1 may have a slider 41, so that the adjustment seat 3 can be movably provided on the first mounting seat 1. In some embodiments of the present application, one of the adjustment seat 3 and the first mounting seat 1 may have a pulley, and the other of the adjustment seat 3 and the first mounting seat 1 may have a slide rail, so that the adjustment seat 3 can be movably provided on the first mounting seat 1.

[0044] The adjustment seat 3 has a first mounting portion 31. In some embodiments of the present application, the first mounting portion 31 can be configured as a through hole. By passing a bolt through the through hole and screwing it into the torsion bar flip mechanism 200, the adjustment seat and the torsion bar flip mechanism 200 can be assembled together. In some embodiments of the present application, the first mounting portion 31 can be configured as a hook. By hooking the hook into the torsion bar flip mechanism 200, the adjustment seat 3 and the torsion bar flip mechanism 200 can be assembled together.

[0045] Since the adjustment seat 3 is movably arranged on the first mounting seat 1, and the adjustment seat 3 is assembled with the torsion bar flipping mechanism 200, by changing the relative position of the adjustment seat 3 and the first mounting seat 1, the position of the torsion bar flipping mechanism 200 can be changed with the position of the adjustment seat 3, thereby achieving the effect of adjusting the position of the torsion bar flipping mechanism 200, and then achieving the effect of confirming the pre-bias value without replacing the flipping mechanism.

[0046] Specifically, the first mounting base 1 carries the torsion bar flipping mechanism 200. The adjustment base 3 may have a slider 41, and the first mounting base 1 may have a slide groove 14, so that the adjustment base 3 can be movably mounted on the first mounting base 1. The adjustment base 3 can be assembled with the torsion bar flipping mechanism 200 via the first mounting portion 31, and the second mounting base 2 can be assembled with the torsion bar flipping mechanism 200 via the second mounting portion 21.

[0047] When it is necessary to determine the pre-bias value of the torsion bar flipping mechanism 200, the relative positions of the adjustment seat 3 and the first mounting seat 1 can be changed first. For example, a first preset value is preset, and the adjustment seat 3 is moved relative to the first mounting seat 1 by the first preset value. At this time, the torsion bar flipping mechanism 200 moves the first preset value with the adjustment seat 3. At this time, it is determined whether the deflection amount of the torsion bar flipping mechanism 200 meets the design requirements. If it meets the design requirements, the pre-bias value of the torsion bar flipping mechanism 200 can be determined as the first preset value.

[0048] If the design requirements are not met, a second preset value is preset based on the deflection of the torsion bar flipping mechanism 200 after adjusting the first preset value, and the adjustment seat 3 is moved by the second preset value relative to the first mounting seat 1. At this time, the torsion bar flipping mechanism 200 moves with the adjustment seat 3 by the second preset value. At this time, it is determined whether the deflection of the torsion bar flipping mechanism 200 meets the design requirements. If the design requirements are met, the pre-deflection value of the torsion bar flipping mechanism 200 can be determined as the second preset value.

[0049] If the design requirements are not met, a third preset value can be determined based on the deflection of the torsion bar flipping mechanism 200 after adjusting the second preset value. The test can be repeated until the deflection of the torsion bar flipping mechanism 200 meets the design requirements. The preset value of the test in which the deflection meets the design requirements is determined as the pre-bias value of the torsion bar flipping mechanism 200.

[0050] In some embodiments of the present application, the deflection of the torsion bar flip mechanism 200 can be obtained by determining the deflection of the cab 300. In some embodiments of the present application, the deflection of the cab 300 can be measured by a sensor.

[0051] The first mounting seat 1 can define an installation space 11, and the installation space 11 can provide an assembly position for the adjustment seat 3, so that at least a portion of the adjustment seat 3 is disposed in the installation space 11. As some embodiments of the present application, a portion of the adjustment seat 3 is disposed in the installation space 11. As some embodiments of the present application, the entire structure of the adjustment seat 3 is disposed in the installation space 11. By disposing at least a portion of the adjustment seat 3 in the installation space 11, the adjustment seat 3 can be reliably moved within the installation space 11, reducing the risk of the relative displacement failure of the adjustment seat 3 and the first mounting seat 1 caused by interference with the external environment, thereby reducing the risk of the adjustment seat 3 and the first mounting seat 1 being stuck.

[0052] The first mounting seat 1 has a first avoidance hole 12, and the first avoidance hole 12 extends along the moving direction of the adjustment seat 3, that is, the first avoidance hole 12 is constructed as a strip-shaped hole extending along the moving direction of the adjustment seat 3. As some embodiments of the present application, the first mounting portion 31 can be constructed as a through hole, and a bolt is passed through the through hole and screwed with the torsion bar flip mechanism 200, so as to achieve the effect of cooperating and assembling the adjustment seat 3 and the torsion bar flip mechanism 200. By setting the first avoidance hole 12 corresponding to the first mounting portion 31, the position of the first avoidance hole 12 can be reasonably set, so that the first avoidance hole 12 can reliably avoid the bolt, reduce the risk of interference between the bolt and the first mounting seat 1, thereby facilitating the smooth screw connection of the bolt and the torsion bar flip mechanism 200, and further achieving the effect of smoothly assembling the adjustment seat 3 and the torsion bar flip mechanism 200.

[0053] Therefore, by setting up the adjustment seat 3, and the adjustment seat 3 is movably set on the first mounting seat 1, the position of the torsion bar flipping mechanism 200 can be adjusted by moving the adjustment seat 3. The operation is simple, which is conducive to achieving the effect of confirming the pre-bias value without replacing the flipping mechanism, thereby reducing the number of calibrations of the pre-bias value of the cab 300 on the whole vehicle, effectively reducing the difficulty of confirming the pre-bias value, and then reducing the time cost required to confirm the pre-bias value, thereby improving the production efficiency of the vehicle.

[0054] In some examples of the present invention, such as Figure 4 As shown, the test bench 100 also includes: a connecting member 4, the adjustment seat 3 has a third mounting portion 32, the first mounting seat 1 has a second avoidance hole 13, the second avoidance hole 13 corresponds to the third mounting portion 32 and extends along the moving direction of the adjustment seat 3, and the connecting member 4 is passed through the second avoidance hole 13 and connected to the third mounting portion 32.

[0055] The adjustment seat 3 has a third mounting portion 32. In some embodiments of the present application, the third mounting portion 32 can be configured as a through hole. In some embodiments of the present application, the third mounting portion 32 can be configured as a hook. This application uses the configuration of the third mounting portion 32 as a through hole as an example. Through holes are easy to process, and configuring the third mounting portion 32 as a through hole can reduce the difficulty of processing the adjustment seat 3, thereby reducing the production cost of the test bench 100.

[0056] The adjustment seat 3 can be assembled with the first mounting seat 1 via the third mounting portion 32. In some embodiments of the present application, the third mounting portion 32 can be configured as a bolt hole, and the connector 4 can be configured as a bolt adapted to the bolt hole. The first mounting seat 1 has a second avoidance hole 13, which is arranged corresponding to the third mounting portion 32. By inserting the connector 4 through the second avoidance hole 13 and screwing it to the third mounting portion 32, the adjustment seat 3 can be assembled with the first mounting seat 1.

[0057] The second avoidance hole 13 extends along the moving direction of the adjustment seat 3, that is, the second avoidance hole 13 is constructed as a strip hole extending along the moving direction of the adjustment seat 3. Such a setting can make the shape of the second avoidance hole 13 reasonable. Since the adjustment seat 3 is movably arranged on the first mounting seat 1, when the adjustment seat 3 moves relative to the first mounting seat 1, the second avoidance hole 13 can avoid the connecting member 4 within the extended length range of the second avoidance hole 13, which is conducive to the connecting member 4 being able to move in the second avoidance hole 13, so that the adjustment seat 3 can move smoothly relative to the first mounting seat 1.

[0058] Furthermore, since the extension length of the first avoidance hole 12 and the second avoidance hole 13 is limited, the first avoidance hole 12 is conducive to limiting the bolt, and the second avoidance hole 13 is conducive to limiting the connecting member 4, reducing the risk of excessive movement of the adjustment seat 3 relative to the first mounting seat 1, causing the adjustment seat 3 to move out of the installation space 11, thereby reducing the risk of failure of the test bench 100. Moreover, during the test, the adjustment seat 3 can be adjusted by toggling the connecting member 4, which is conducive to reducing the difficulty of adjustment.

[0059] In some examples of the present invention, such as Figure 4 As shown, the adjustment seat 3 has one of the slide groove 14 or the slider 41 , and the first mounting seat 1 has the other of the slide groove 14 or the slider 41 , and the slider 41 is slidably disposed in the slide groove 14 .

[0060] In some embodiments of the present application, the adjustment seat 3 has a slider 41, and the first mounting seat 1 has a slide groove 14. In some embodiments of the present application, the adjustment seat 3 has a slide groove 14, and the first mounting seat 1 has a slider 41. By slidably setting the slider 41 in the slide groove 14, the adjustment seat 3 can be movably set on the first mounting seat 1, and by cooperating and assembling the adjustment seat 3 with the torsion bar flipping mechanism 200, the position of the torsion bar flipping mechanism 200 can be adjusted by changing the relative position of the adjustment seat 3 and the first mounting seat 1.

[0061] Compared with movably arranging the adjustment seat 3 on the first mounting seat 1 by other means, the cooperation between the slider 41 and the slide groove 14 can reduce the production difficulty of the adjustment seat 3 and the first mounting seat 1, thereby helping to reduce the production cost of the test bench 100. Moreover, the cooperation between the slider 41 and the slide groove 14 is reliable, which can effectively reduce the risk of jamming of the adjustment seat 3 and the first mounting seat 1, thereby making the position adjustment of the adjustment seat 3 reliable, thereby achieving the effect of smoothly adjusting the position of the torsion bar flipping mechanism 200.

[0062] In some examples of the present invention, such as Figure 3-Figure 4 As shown, the adjustment base 3 has a scale bar 33 .

[0063] In some embodiments of the present application, a scale bar 33 may be printed on the adjustment seat 3. In some embodiments of the present application, a scale bar 33 may be etched on the adjustment seat 3. However, the present application is not limited thereto. By providing a scale bar 33 on the adjustment seat 3, the relative position of the adjustment seat 3 and the first mounting seat 1 can be accurately adjusted. Furthermore, when the deflection of the torsion bar flipping mechanism 200 meets the design requirements, the pre-bias value of the torsion bar flipping mechanism 200 can also be accurately determined by reading the scale of the scale bar 33, thereby improving the reliability of the pre-bias value of the torsion bar flipping mechanism 200 when testing.

[0064] In some examples of the present invention, the test bench 100 may further include a sensor (not shown in the figures), the sensor being adapted to detect the deflection of the cab 300 connected to the torsion bar flip mechanism 200 .

[0065] In some embodiments of the present application, the sensor may be configured as an infrared sensor. In some embodiments of the present application, the sensor may be configured as an ultrasonic sensor. However, the present application is not limited thereto. In some embodiments of the present application, the sensor may be located behind the cab 300. It should be noted that, along the length of the vehicle, the sensor is located at one end of the cab 300 near the rear. This arrangement allows for a reasonable sensor placement, facilitating accurate detection of the deflection of the cab 300 connected to the torsion bar flip mechanism 200 by the sensor. This allows the sensor to determine whether the pre-bias value meets the vehicle's design requirements based on the deflection of the cab 300 connected to the torsion bar flip mechanism 200. Furthermore, compared to manually measuring the deflection of the cab 300 connected to the torsion bar flip mechanism 200, detecting the deflection of the cab 300 connected to the torsion bar flip mechanism 200 using the sensor can improve the accuracy of the deflection detection results, thereby accurately determining whether the pre-bias value of the torsion bar flip mechanism 200 meets the design requirements, thereby further improving the reliability of testing the pre-bias value of the torsion bar flip mechanism 200.

[0066] In some examples of the present invention, such as Figure 1-Figure 2 As shown, the test bench 100 may further include: a second mounting seat 2, wherein the first mounting seat 1 and the second mounting seat 2 are spaced apart along the first direction; the second mounting seat 2 has a second mounting portion 21, and the second mounting portion 21 is suitable for cooperating with the torsion bar flipping mechanism 200.

[0067] Among them, along the first direction, that is, Figure 1In the X direction of the test bench 100, the first mounting seat 1 and the second mounting seat 2 are arranged opposite each other, and the first mounting seat 1 and the second mounting seat 2 are arranged spaced apart. In some embodiments of the present application, the spacing between the first mounting seat 1 and the second mounting seat 2 can be adapted to the width of the torsion bar flipping mechanism 200. Such an arrangement can make the arrangement positions of the first mounting seat 1 and the second mounting seat 2 reasonable, and facilitate the first mounting seat 1 and the second mounting seat 2 to cooperate with each other and jointly support the torsion bar flipping mechanism 200. In some embodiments of the present application, along the height direction of the test bench 100, the torsion bar flipping mechanism 200 is arranged on the upper side of the first mounting seat 1 and the second mounting seat 2.

[0068] The adjustment seat 3 has a first mounting portion 31, and the second mounting seat 2 has a second mounting portion 21. In some embodiments of the present application, the first mounting portion 31 and the second mounting portion 21 can both be configured as through holes. By passing bolts through the through holes and screwing them into the torsion bar flip mechanism 200, the adjustment seat 3 and the second mounting seat 2 can be assembled with the torsion bar flip mechanism 200. In some embodiments of the present application, the first mounting portion 31 and the second mounting portion 21 can both be configured as hooks. By hooking the hooks into the torsion bar flip mechanism 200, the adjustment seat 3 and the second mounting seat 2 can be assembled with the torsion bar flip mechanism 200.

[0069] Specifically, the first mounting seat 1 and the second mounting seat 2 are arranged opposite to each other and spaced apart along the first direction. Figure 1 The first mounting seat 1 and the second mounting seat 2 are arranged opposite and spaced apart in the X direction, and the first mounting seat 1 and the second mounting seat 2 jointly support the torsion bar flip mechanism 200. By providing the second mounting seat 2, the installation stability of the torsion bar flip mechanism 200 can be improved, which is conducive to improving the reliability of the test bench 100.

[0070] In some examples of the present invention, such as Figure 1-Figure 2 As shown, the test bench 100 may further include: a base 5 , on which the first mounting seat 1 and the second mounting seat 2 are both arranged.

[0071] In some embodiments of the present application, the first mounting seat 1 and the second mounting seat 2 can be directly connected to the base 5, so that the first mounting seat 1 and the second mounting seat 2 are both provided on the base 5. In some embodiments of the present application, the first mounting seat 1 and the second mounting seat 2 can be indirectly connected to the base 5 through the reinforcement component 6, so that the first mounting seat 1 and the second mounting seat 2 are both provided on the base 5.

[0072] In some embodiments of the present application, the base 5 can be placed on the ground. In some embodiments of the present application, the base 5 can be placed on a test bench. However, the present application is not limited thereto. The present application takes the base 5 placed on the ground as an example for explanation. By placing the base 5 on the ground, the placement stability of the base 5 can be improved, thereby improving the stability of the first mounting seat 1 and the second mounting seat 2, reducing the risk of test deviation or even test failure caused by position changes of the first mounting seat 1 and the second mounting seat 2 during the test, and thereby improving the working reliability of the test bench 100 and the reliability of the pre-bias value test results.

[0073] In some examples of the present invention, such as Figure 2 As shown, the test bench 100 may further include: a reinforcing component 6 , which is disposed on the base 5 , and the first mounting seat 1 and the second mounting seat 2 are both disposed on the reinforcing component 6 .

[0074] The first mounting base 1 and the second mounting base 2 can both be indirectly connected to the base 5 via a reinforcement assembly 6. In some embodiments of the present application, the reinforcement assembly 6 and the base 5 can be connected by bolts so that the reinforcement assembly 6 is disposed on the base 5. In some embodiments of the present application, the reinforcement assembly 6 and the base 5 can be connected by welding so that the reinforcement assembly 6 is disposed on the base 5. However, the present application is not limited thereto.

[0075] In some embodiments of the present application, the first mounting seat 1 and the second mounting seat 2 can be connected to the reinforcement assembly 6 by bolts, so that the first mounting seat 1 and the second mounting seat 2 are both provided on the reinforcement assembly 6. In some embodiments of the present application, the first mounting seat 1 and the second mounting seat 2 can be connected to the reinforcement assembly 6 by welding, so that the first mounting seat 1 and the second mounting seat 2 are both provided on the reinforcement assembly 6. However, the present application is not limited thereto.

[0076] Specifically, the reinforcement assembly 6 is threaded onto the base 5, and the first mounting seat 1 and the second mounting seat 2 are both bolted to the reinforcement assembly 6, so that the first mounting seat 1 and the second mounting seat 2 are indirectly connected to the base 5 via the reinforcement assembly 6, thereby improving the stability of the first mounting seat 1 and the second mounting seat 2. Furthermore, compared with directly connecting the first mounting seat 1 and the second mounting seat 2 to the base 5, the indirect connection of the first mounting seat 1 and the second mounting seat 2 to the base 5 via the reinforcement assembly 6 can improve the structural strength of the test bench 100, thereby increasing the service life of the test bench 100. In addition, by providing the reinforcement assembly 6, the test bench 100 can reliably and stably support the torsion bar tilting mechanism 200 and the cab 300, which is conducive to improving the accuracy of the test results.

[0077] In some examples of the present invention, such as Figure 2As shown, the reinforcement component 6 may include: a first mounting bracket 61 and a second mounting bracket 62. The first mounting bracket 61 and the second mounting bracket 62 are spaced apart along the first direction. The first mounting bracket 61 defines a first receiving space 611. A portion of the first mounting seat 1 is disposed in the first receiving space 611 and is connected to the first mounting bracket 61. The second mounting bracket 62 defines a second receiving space 621. A portion of the second mounting seat 2 is disposed in the second receiving space 621 and is connected to the second mounting bracket 62.

[0078] Among them, along the first direction, that is, Figure 1 In the X direction, the first mounting bracket 61 and the second mounting bracket 62 are arranged opposite each other, and the first mounting bracket 61 and the second mounting bracket 62 are spaced apart. In some embodiments of the present application, the spacing between the first mounting bracket 61 and the second mounting bracket 62, the spacing between the first mounting seat 1 and the second mounting seat 2, and the width of the base 5 are adapted. Such an arrangement can make the positions of the first mounting bracket 61 and the second mounting bracket 62 reasonably arranged, and facilitate the smooth assembly of the first mounting seat 1 and the second mounting seat 2 to the base 5 via the reinforcement assembly 6.

[0079] The first mounting bracket 61 defines a first receiving space 611, which can provide an assembly location for the first mounting seat 1. In some embodiments of the present application, the first mounting seat 1 and the first mounting bracket 61 can be connected by bolts, so that a portion of the first mounting seat 1 is disposed in the first receiving space 611. In some embodiments of the present application, the first mounting seat 1 and the first mounting bracket 61 can be connected by screws, so that a portion of the first mounting seat 1 is disposed in the first receiving space 611. However, the present application is not limited thereto.

[0080] The second mounting bracket 62 defines a second receiving space 621, which can provide an assembly location for the second mounting base 2. In some embodiments of the present application, the second mounting base 2 and the second mounting bracket 62 can be connected by bolts, so that a portion of the second mounting base 2 is disposed in the second receiving space 621. In some embodiments of the present application, the second mounting base 2 and the second mounting bracket 62 can be connected by screws, so that a portion of the second mounting base 2 is disposed in the second receiving space 621. However, the present application is not limited thereto.
