Description

Technical Field

[0001] The utility model relates to the field of automobiles, in particular to a test bench. Background Art

[0002] The wheel speed sensor is a sensor used to test the rotation speed of the car wheels. The wheel speed sensor is usually installed on parts near the wheel that do not rotate with the wheel, such as the half-axle sleeve, steering knuckle, brake base plate, etc. In the actual driving process of the car, there are both vehicle bumps and turns. Therefore, the wheel speed sensor will move up and down and swing left and right after being installed on the vehicle.

[0003] The current durability test of wheel speed sensors is to conduct up and down movement and left and right swing separately through different test benches. Such a design not only takes a long time to test, but also is inconsistent with the actual loading conditions. It cannot fully simulate the actual loading operation conditions, affecting the accuracy of the test data. Utility Model Content

[0011] For the convenience of demonstration, the test product is taken as a wheel speed sensor as an example for explanation.

[0012] By adopting the above technical solution, the fixing mechanism connects and fixes a part of the wheel speed sensor, the moving mechanism connects the other part of the wheel speed sensor, the moving mechanism connects the connecting part, the connecting part connects the lifting mechanism and the sliding mechanism, the lifting mechanism drives the connecting part to move up and down along the first direction to drive the moving mechanism to move synchronously, thereby driving the wheel speed sensor to move up and down along the first direction, and the sliding mechanism drives the connecting part to rotate around the first direction at a set angle to drive the moving mechanism to move synchronously, thereby driving the wheel speed sensor to rotate around the first direction at a set angle.

Compared with the previous separation of up and down movement and left and right swing through different test benches, the test bench can simultaneously realize the up and down movement and left and right swing of the test product (i.e., rotate around the first direction by a set angle), simulating the actual loading environment, reducing the test bench and saving test time.

The first connecting member is connected to the connecting part, which drives the connecting part to rotate around the first direction at a set angle, thereby driving the moving mechanism connected to the connecting part to move synchronously, so that the wheel speed sensor connected to the moving mechanism rotates around the first direction at a set angle to achieve left and right swing.

[0021] By adopting the above technical scheme, one end of the first connecting rod passes through the first through hole and is connected to the first disc. When the rotation angle of the wheel speed sensor needs to be changed, the position of the one end of the first connecting rod on the first disc can be changed. Since the first through hole extends radially along the first disc, when the rotation angle of the wheel speed sensor around the first direction needs to be reduced, one end of the first connecting rod can be connected to a position close to the center of the first disc. When the rotation angle of the wheel speed sensor around the first direction needs to be increased, one end of the first connecting rod can be connected to a position far away from the center of the first disc.

[0027] By adopting the above technical scheme, one end of the second connecting rod passes through the second through hole and is connected to the second disc. When it is necessary to change the length of the up and down movement of the wheel speed sensor, the position of one end of the second connecting rod on the second disc can be changed. Since the second through hole extends radially along the second disc, when it is necessary to reduce the length of the up and down movement of the wheel speed sensor along the first direction, one end of the second connecting rod can be connected to a position close to the center of the second disc. When it is necessary to increase the length of the up and down movement of the wheel speed sensor along the first direction, one end of the second connecting rod can be connected to a position far away from the center of the second disc. This can meet the needs of different types of wheel speed sensors, simulate different loading environments, and has a wide range of applications.

When it is necessary to change the position of the connecting part, the connecting part can be connected to the first connecting column through other plug interfaces, so as to facilitate the adjustment of the position of the fixing mechanism and the connecting part. When the position of the connecting part changes, the position between the connecting part and the lifting mechanism and the sliding mechanism will also change accordingly, and the movement of the connecting part driven by the lifting mechanism and the sliding mechanism will also change, so as to adjust the length of the connecting part moving up and down in the first direction and the angle of rotation around the first direction, so as to meet the needs of different types of wheel speed sensors and simulate different loading environments.

[0044] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0045] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0046] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] The present embodiment provides a test bench that can be used for durability testing of automotive parts with wiring harness connectors, such as durability testing of all wheel speed sensors that simulate the actual vehicle layout. For ease of description, the present embodiment uses the test product, a wheel speed sensor, as an example for explanation.

[0048] For example, reference Figures 1 to 3 The test bench comprises: a frame 1, a first connecting column 2, a second connecting column 3, a fixing mechanism 4, a moving mechanism 5, a connecting portion 6, a lifting mechanism 7 and a sliding mechanism 8, wherein the fixing mechanism 4 is used to connect a part of a wheel speed sensor (not shown in the figure), the moving mechanism 5 is used to connect another part of the wheel speed sensor, the connecting portion 6 is connected to the moving mechanism 5, and the connecting portion 6 is moved along a first direction (i.e. Figure 1 The lifting mechanism 7 is connected to the connecting portion 6 and can drive the connecting portion 6 to move in a first direction (ie, Figure 1 The sliding mechanism 8 is connected to the connecting portion 6, and can drive the connecting portion 6 to rotate around the first direction by a set angle, so as to drive the wheel speed sensor to rotate around the first direction by a set angle, for example, 15°, 19°, 25°, 30°, etc. The embodiment of the present application does not limit the specific rotation angle of the wheel speed sensor around the first direction, and can be selected according to actual needs.

[0049] Exemplarily, the fixing mechanism 4 connects and fixes a part of the wheel speed sensor, the moving mechanism 5 connects to the other part of the wheel speed sensor, the moving mechanism 5 is connected to the connecting part 6, the connecting part 6 is connected to the lifting mechanism 7 and the sliding mechanism 8, the lifting mechanism 7 drives the connecting part 6 to move up and down along the first direction to drive the moving mechanism 5 to move synchronously, thereby driving the wheel speed sensor to move up and down along the first direction, and the sliding mechanism 8 drives the connecting part 6 to rotate around the first direction at a set angle to drive the moving mechanism 5 to move synchronously, thereby driving the wheel speed sensor to rotate around the first direction at a set angle.

[0050] That is to say, the test bench can make the wheel speed sensor realize the wheel speed sensor in the first direction (i.e. Figure 1 The X direction shown in the figure) moves up and down and around the first direction (i.e. Figure 1 The test bench can realize the up-down movement and the left-right swing (i.e., rotate the set angle around the first direction) to simulate the actual loading situation (i.e., there are both vehicle bumps and turns in the actual operation of the car). Compared with the previous test benches that separately perform the up-down movement and the left-right swing through different test benches, the test bench can realize the up-down movement and the left-right swing (i.e., rotate the set angle around the first direction), simulate the actual loading environment, reduce the number of test benches, save test time, and be closer to the actual loading environment, so that the test data is more accurate.

[0051] For example, reference Figure 1 and Figure 3 The frame 1 includes a receiving space 10 to accommodate the above-mentioned sliding mechanism 8 and part of the lifting mechanism 7. The frame 1 is a six-sided hollow cube. The upper surface of the frame 1 is connected with two Figure 1 The two beams 11 extend in the second direction (ie, Figure 1 The three insertion ports 12 are arranged at intervals in the Y direction as shown to form three insertion ports 12 for the later-described first extension rod 42 and the above-mentioned connecting portion 6 to be inserted.

[0052] The embodiment of the present application does not limit the specific shape of the frame 1, which can be a cube with six hollow sides, a rectangular parallelepiped with five hollow sides, or other irregular shapes, as long as it can provide accommodation space and support for the sliding mechanism 8 and part of the lifting mechanism 7. Similarly, the embodiment of the present application does not limit the number of beams 11, which can also be three, four or five beams 11.

[0053] For example, reference Figures 3 to 5 , the first connecting column 2 is along the second direction (ie Figure 4 The second connecting column 3 extends in the second direction (ie Figure 4The first connecting column 2 is arranged on the right side of the frame 1, and the second connecting column 3 is arranged on the left side of the frame 1. The first connecting column 2 is provided with three slide grooves extending along the second direction. The above-mentioned lifting mechanism 7, sliding mechanism 8 and connecting part 6 are respectively connected to the first connecting column 2 in a detachable manner through one of the slide grooves. For the convenience of description, the one connected to the connecting part 6 is called the first slide groove 20, the one connected to the lifting mechanism 7 is called the second slide groove 21, and the one connected to the sliding mechanism 8 is called the third slide groove 22.

[0054] Exemplarily, the connecting portion 6 can change its position in the first slide groove 20 to change the positional relationship with the fixing mechanism 4, the lifting mechanism 7 and the sliding mechanism 8 to adapt to different types of wheel speed sensors. Similarly, the lifting mechanism 7 and the sliding mechanism 8 can also change their positions in the second slide groove 21 and the third slide groove 22 to change the positional relationship between the lifting mechanism 7 and the sliding mechanism 8 and the connecting portion 6 to change the length of the connecting portion 6 moving up and down along the first direction and the angle of rotation around the first direction. When the wheel speed sensor is installed on different vehicle models, the detection requirements will be different. Such a design can adapt to different detection requirements of customers.

[0055] For example, reference Figure 1 and Figure 2 The second connecting column 3 is provided with a slide groove extending along the second direction, which can be called the fourth slide groove 30 for the convenience of description. The above-mentioned fixing mechanism 4 is detachably connected to the second connecting column 3 through the fourth slide groove 30. Similarly, the fixing mechanism 4 can change its position in the fourth slide groove 30 to change the positional relationship with the moving mechanism 5, so as to adapt to different wheel speed sensors, with high practicality and strong adaptability.

[0056] It should be noted that the embodiment of the present application does not limit the number of slide grooves specifically provided on the first connecting column 2 and the second connecting column 3. The first connecting column 2 may have three or more slide grooves, such as four or five slide grooves, and the second connecting column 3 may have one or more slide grooves, such as two or three slide grooves.

[0057] For example, reference Figure 1 and Figure 3 The fixing mechanism 4 includes a fixing plate 40, a first bearing seat 41, a first extension rod 42, a first connecting plate 43 and an L-shaped bracket 44. The first extension rod 42 extends along a first direction. The fixing plate 40 is sleeved on the first extension rod 42. A part of the wheel speed sensor is connected to the fixing plate 40. The first bearing seat 41 is connected to the first extension rod 42 and is arranged below the fixing plate 40 along the first direction for supporting the fixing plate 40. The first connecting plate 43 extends along a second direction and is detachably connected to the upper surface of the frame 1 and the two beams 11 mentioned above. The first extension rod 42 passes through the first connecting plate 43 and any one of the above-mentioned plug-in interfaces 12, and is connected to the L-shaped bracket 44.

[0058] The L-shaped bracket 44 is detachably connected to the second connecting column 3 through the above-mentioned fourth slide groove 30, so that the fixing mechanism 4 is detachably connected to the second connecting column 3 through the fourth slide groove 30. Along the first direction, the first connecting plate 43 is connected to the fourth bearing disk 45, and the first extension rod 42 passes through the fourth bearing disk 45, so that the first extension rod 42 is supported and fixed.

[0059] For example, continue to refer to Figure 1 and Figure 3 The connecting portion 6 is a rod-shaped structure, such as the second extension rod 61 shown in the embodiment of the present application. The moving mechanism 5 includes a moving plate 50, which is sleeved on the second extension rod 61. Another part of the wheel speed sensor is connected to the moving plate 50. A second bearing seat 51 is provided on the second extension rod 61. The second bearing seat 51 is arranged below the moving plate 50 along the first direction for supporting the moving plate 50. The second extension rod 61 passes through the second connecting plate 52 and any one of the above-mentioned plug-in interfaces 12. It can pass through the same plug-in interface 12 as the first extension rod 42, or it can pass through a different plug-in interface 12 with the first extension rod 42, and is detachably connected to the first connecting column 2 through the above-mentioned first slide groove 20.

[0060] The second connecting plate 52 extends along the second direction and is detachably connected to the upper surface of the frame 1 and the two cross beams 11 mentioned above. Along the first direction, the second connecting plate 52 is connected to the second bearing disk 53, and the second extension rod 61 passes through the second bearing disk 53. The first connecting column 2 is connected to the third bearing disk 54, and the second extension rod 61 passes through the third bearing disk 54, so that the second extension rod 61 is supported and fixed.

[0061] For example, reference Figures 3 to 5 The sliding mechanism 8 is arranged in the above-mentioned accommodating space 10. The sliding mechanism 8 includes a first driving member 80 and a first connecting member 82. The first driving member 80 is connected to the inverted L-shaped mounting seat 81. The inverted L-shaped mounting seat 81 is connected to the first connecting column 2 through the above-mentioned third sliding groove 22. The first driving member 80 is connected to the first connecting member 82. The first driving member 80 can select a first motor 800 or other driving devices. The first connecting member 82 is connected to the second extension rod 61. The first motor 800 can drive the first connecting member 82 to move, so as to drive the second extension rod 61 to rotate around the first direction by a set angle, thereby driving the moving plate 50 connected to the second extension rod 61 to move synchronously, so that the wheel speed sensor connected to the moving plate 50 rotates around the first direction by a set angle to achieve left and right swing.

[0062] For example, continue to refer to Figures 3 to 5The first connecting member 82 includes a first disk 820 and a first connecting rod 821. The output shaft of the first motor 800 is connected to the first disk 820. The first connecting rod 821 is a crank rocker structure. The crank rocker structure includes a crank connected to the first disk 820 and a rocker fixedly connected to the second extension rod 61. The rocker is connected to the second extension rod 61 through a first bearing disk 823. The first bearing disk 823 is sleeved on the first extension rod 61.

[0063] The first motor 800 can drive the first disc 820 to rotate, driving one end of the first connecting rod 821 (i.e., the crank) to rotate around the center of the first disc 820, and the other end of the first connecting rod 821 (i.e., the rocker) to rotate around the first direction, thereby driving the second extension rod 61 to rotate around the first direction at a set angle, such as 15°, 19°, 25°, 30°, etc., but not limited to this, and can be selected according to actual needs. The first connecting rod 821 converts the circular motion of the first disc 820 into a rotation of the second extension rod 61 around the first direction, that is, simulating the left and right swing in an actual loading environment.

[0064] For example, reference Figure 4 and Figure 5 The first disc 820 is provided with a first through hole 822 extending along its radial direction, and one end of the first connecting rod 821 passes through the first through hole 822 and is connected to the first disc 820. When the rotation angle of the wheel speed sensor needs to be changed, the position of one end of the first connecting rod 821 on the first disc 820 can be changed. Since the first through hole 822 extends along the radial direction of the first disc 820, when the rotation angle of the wheel speed sensor around the first direction needs to be reduced, one end of the first connecting rod 821 can be connected to a position close to the center of the first disc 820. When the rotation angle of the wheel speed sensor around the first direction needs to be increased, one end of the first connecting rod 821 can be connected to a position far away from the center of the first disc 820. This can meet the needs of different types of wheel speed sensors and simulate different loading environments, and has a wide range of applications.

[0065] For example, reference Figures 3 to 5 The lifting mechanism 7 includes a second driving member, a second connecting member 71 and a sliding member 72. The second connecting member 71 and the sliding member 72 together constitute a crank slider mechanism. The second driving member passes through an L-shaped support seat 73. The L-shaped support seat 73 is connected to the lower surface of the frame 1. The second driving member can select a second motor or other driving device. Only the output shaft 70 of the second motor is shown in the figure. The output shaft 70 of the second motor is connected to the second connecting member 71. The second connecting member 71 is connected to the sliding member 72. The sliding member 72 is connected to the second extension rod 61.

[0066] The second motor can drive the second connecting member 71 to move, so as to drive the sliding member 72 to move up and down along the first direction, thereby driving the second extension rod 61 to move up and down along the first direction, thereby driving the movable plate 50 connected to the second extension rod 61 to move synchronously, so that the wheel speed sensor connected to the movable plate 50 moves up and down along the first direction, that is, simulating the up and down movement in the actual loading environment.

[0067] For example, continue to refer to Figures 3 to 5 The second connecting member 71 includes a second disc 710 and a second connecting rod 711, the second disc 710 is connected to the output shaft 70 of the second motor, one end of the second connecting rod 711 is connected to the second disc 710, and the other end of the second connecting rod 711 is connected to the sliding member 72, the sliding member 72 is connected to the frame 1 in a slidable manner along the first direction, for example, it is connected to the frame 1 through two slide rails 720 spaced apart along the second direction, the two slide rails 720 are connected to the frame 1 and extend along the first direction, the sliding member 72 includes a sliding seat 721 extending along the second direction, one side of the sliding seat 721 is connected to the two slide rails 720, and the other side is connected to the first connecting column 2 through the above-mentioned second slide groove 21.

[0068] Exemplarily, the second motor can drive the second disc 710 to rotate, so as to drive one end of the second connecting rod 711 to rotate around the center of the second disc 710, and the other end of the second connecting rod 711 to move up and down along the first direction, thereby driving the slide 721 to move up and down along the first direction, so as to drive the second extension rod 61 to move up and down along the first direction. The second connecting rod 711 converts the circular motion of the second disc 710 into the up and down motion of the second extension rod 61 along the first direction, that is, simulating the up and down motion in the actual loading environment.

[0069] For example, continue to refer to Figures 3 to 5 The second disc 710 is provided with a second through hole 722 extending along its radial direction, and one end of the second connecting rod 711 passes through the second through hole 722 and is connected to the second disc 710. When it is necessary to change the length of the up and down movement of the wheel speed sensor, the position of one end of the second connecting rod 711 on the second disc 710 can be changed. Since the second through hole 722 extends along the radial direction of the second disc 710, when it is necessary to reduce the length of the up and down movement of the wheel speed sensor along the first direction, one end of the second connecting rod 711 can be connected to a position close to the center of the second disc 710. When it is necessary to increase the length of the up and down movement of the wheel speed sensor along the first direction, one end of the second connecting rod 711 can be connected to a position far away from the center of the second disc 710. This can meet the needs of different types of wheel speed sensors and simulate different loading environments, and has a wide range of applications.
