Description

Technical Field

[0001] The present invention relates to the test of an accelerator pedal, and particularly to a test tooling and a test method for an accelerator pedal. Background Art

[0002] Currently, there is no test tooling on the market that can be well applied to the accelerator pedal. Generally, the test tooling uses actuators such as cylinders to apply a vertical force to a point on the accelerator pedal. As the accelerator pedal rotates, the application angle of the force shifts, that is, as the pedal rotates continuously, the initial vertical force on its end face becomes an obliquely directed force, which is quite different from the force that is always perpendicular to the bottom surface of a person's foot during the actual use of the pedal. Therefore, the existing test tooling cannot effectively conduct accurate tests on the accelerator pedal and deviates from the actual use situation.

[0003] Therefore, it is necessary to design a new type of test tooling for the accelerator pedal to overcome the above defects. Summary of the Invention

[0012] As an alternative technical solution, an adjusting rod is provided in the housing and is threadedly connected thereto, one end of the adjusting rod is rotatably connected to the base, and the other end extends to the outside of the housing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] To further understand the purpose, structure, features and functions of the present invention, hereby in conjunction with the embodiments and Figures 1-9The detailed description is as follows.

[0032] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of the present invention. The throttle pedal test tooling according to an embodiment of the present invention includes at least one pressing plate assembly 8, and the pressing plate assembly 8 has the same rotational stroke as the throttle pedal 9; a connecting rod assembly, the connecting rod assembly includes an input end and an output end, and the output end is adjustably connected to the pressing plate assembly 8; a power assembly, the power assembly is rotationally connected to the input end, and the power assembly has an output stroke that is adapted to the rotational stroke and has a periodic output stroke.

[0033] In practice, those skilled in the art can understand that the throttle pedal 9 is disposed on the tabletop 1 and is detachably connected, and the assembly of the throttle pedal 9 and the stroke debugging of the power assembly are realized through the detachable connection method; the pressing plate assembly 8 obtains the output stroke information required by the power assembly by pressing the throttle pedal 9, and adjusts its own output stroke through the output stroke information. This output stroke can be understood as the output stroke that matches the angular change amount of the throttle pedal 9. In order to make the pressing plate assembly 8 have the same angular change amount as the throttle pedal 9, the power assembly transmits the output stroke to the pressing plate assembly 8 through the connecting rod assembly, so that the pressing plate assembly 8 has the same stroke as the throttle pedal 9. It should be noted that after the pressing plate assembly 8 has the same stroke as the throttle pedal 9, its rotation path is an arc line. In this embodiment, the pressing plate assembly 8 includes a pressing plate 82 and an adjusting plate 81. The lower end surface of the pressing plate 82 forms a surface contour that fits the upper surface of the throttle pedal 9. Those skilled in the art can understand that in practice, the pressing plate assembly 8 acts on the surface of the throttle pedal 9 through the pressing plate 82, and the contact formed with the surface of the throttle pedal 9 is surface-to-surface contact. Therefore, when the pressing plate assembly 8 has the same angular rotation as the throttle pedal 9, the pressing plate 82 can always maintain a force perpendicular to the surface of the throttle pedal 9 during the process of pressing and rotating the throttle pedal 9. This kind of acting force not only increases the acting surface of the force and reduces the damage degree to the surface of the throttle pedal 9, but also can effectively imitate the process of stepping on the throttle pedal 9 by the bottom surface of the human foot, achieving an ideal simulation test effect; in this embodiment, the connecting rod assembly is used to transmit the force output by the power assembly and feedback the output force to the pressing plate assembly in a rotational form, so that the pressing plate assembly can fit the surface of the throttle pedal 9 and rotate. It should be noted that in this embodiment, the connecting rod assembly can include various structural forms. In practice, the connecting rod assembly used can realize the linkage of a single pressing plate assembly 8, and can also realize the linkage of multiple pressing plate assemblies 8. The following will make a detailed description in combination with specific connection forms.

[0034] I. Connection state I between the connecting rod assembly and the pressing plate assembly 8:

[0035] In practice, the connecting rod assembly includes a support rod 4, the end of the support rod 4 is adjustably connected to the pressing plate assembly 8, and the rotating shaft of the support rod 4 and the accelerator pedal 9 are arranged on the same rotation axis. Here, those skilled in the art can understand that only when the rotating shafts of the support rod 4 and the accelerator pedal 9 are on the same axis, the rotation angle of the support rod 4 will change synchronously with the rotation angle of the accelerator pedal 9; a connecting rod 7, one end of the connecting rod 7 is fixedly connected to the support rod 4; a main transmission rod 2, the other end of the connecting rod 7 is rotatably connected to the main transmission rod 2, and the other end of the main transmission rod 2 is rotatably connected to the output end of the power assembly. Here, the power assembly transmits force to the connecting rod 7 through the main transmission rod 2. Since the connecting rod 7 is fixedly connected to the support rod 4, that is, the connecting rod 7 rotates around the axis of the support rod 4 on the support rod 4, and since the output of the power assembly is a periodic output stroke, in practice, the power assembly can adopt a periodic motion with a continuous output stroke. Those skilled in the art can understand that the connecting rod 7 makes a reciprocating periodic swinging motion around the axis of the support rod, so that the pressing plate assembly 8 has the same arc motion as the accelerator pedal 9. The arc motion of the accelerator pedal 9 means the arc stroke during the pressing process of the accelerator pedal 9 around its rotating shaft and the arc stroke during the return process. Generally, the paths of the pressing stroke and the return stroke of the accelerator pedal 9 are the same, that is, the rotation angles are the same.

[0036] In this embodiment, the support rod 4 can achieve two connection methods, including:

[0037] One end is adjustably connected to the pressing plate assembly 8 or both ends are respectively and synchronously adjustably connected to a pressing plate assembly 8; the support rod 4 is positioned through the bearing seats 12 arranged at both ends. Those skilled in the art can understand that the bearing seat 12 includes a bearing sleeved on the support rod 4 and a support for fixing the bearing. At the same time, the support is fixedly connected to the table 1, and the support rod 4 is arranged parallel to the table 1.

[0038] In practice, when using one pressing plate assembly 8 to connect with the support rod 4, the pressing plate assembly 8 is adjustably connected to the end of the rod 4, and a connecting rod 7 is fixedly connected to the middle of the support rod 4.

[0039] In practice, when using two pressing plate assemblies 8 to connect with the support rod 4, the pressing plate assemblies 8 are respectively arranged at both ends of the support rod 4 and are adjustably connected to the support rod 4, and a connecting rod 7 is fixedly connected to the middle of the support rod 4. It should be noted that the setting angles of the pressing plate assemblies 8 at both ends are the same.

[0040] II. Connection state II between the connecting rod assembly and the pressing plate assembly 8:

[0041] Different from the above embodiments, in this embodiment, the connection of the two sets of pressing plate assemblies 8 is realized by adopting a transmission rod 6.

[0042] Here, both ends of the transmission rod 6 are respectively rotatably connected to the link assembly. Specifically, two support rods 4 are assembled on the table surface 1, and the two support rods 4 are arranged in parallel. At the end of the support rod 4, one pressing plate assembly 8 or two pressing plate assemblies 8 can be adjustably connected. At the same time, a link 7 is fixedly connected to one of the support rods 4. The link 7 is rotatably connected to the main transmission rod 2, and a swing rod 5 is fixedly connected to this support rod 4. A swing rod 5 is also fixedly connected to the other support rod 4. The two swing rods 5 are rotatably connected by a transmission rod 6, and the linkage of the two sets of pressing plate assemblies 8 can be realized. Similarly, when the power is sufficient and the accuracy can be achieved, this kind of throttle pedal test tooling can be equipped with multiple pressing plate assemblies 8 at the same time. This embodiment will not make a detailed description of it.

[0043] Further, in the above embodiment, the length of the transmission rod 6 is adjustable, including a middle section rod 61 and rod seats 63 adjustably arranged at both ends of the middle section rod 61. The rod seats 63 are rotatably connected to the swing rod 5. There are various connection methods between the middle section rod 61 and the rod seats 63, and their purposes are all to realize the adjustable length of the transmission rod 6. In practice, a locking member 62 is detachably connected between the middle section rod 61 and the rod seats 63. After adjusting the lengths of the middle section rod 61 and the rod seats 63 and then fixing them by the locking member 62, the length adjustment of the transmission rod 6 can be realized. In this embodiment, the length adjustment is used to realize the position adjustment of the two swing rods 5. That is, those skilled in the art can understand that by adjusting the length of the transmission rod 6, the two swing rods 5 are adjusted to be parallel, so as to realize the linkage of the two sets of pressing plate assemblies 8, and this linkage can ensure the consistency of the rotation stroke.

[0044] Please refer to Figure 2 and Figure 3, the structure and connection method of the power assembly are shown in the figure. In order to make the pressing plate assembly 8 adjustable, the power assembly is the stroke adjustment assembly 3. The stroke adjustment assembly 3 includes a motor 31. The stroke adjuster 33 includes a housing 333. A straight track is formed in the housing 333 and is arranged in the same plane as the axis of the output shaft of the motor 31. This straight track is perpendicular to the axis of the output shaft of the motor 31. A base 332 that can be adjustably fixed at any position on the track is movably connected to the straight track. A connecting member 3322 is rotatably connected to the base 332. The other end of the connecting member 3322 is rotatably connected to the input end of the link assembly. That is, in the figure, the connecting member 3322 is rotatably connected to the main transmission rod 2. The rotation axis of the connecting member 3322 is in the same plane as the track and the output shaft of the motor 31, and the rotation axis of the connecting member 3322 is parallel to the output shaft of the motor 31. The output shaft of the motor 31 is fixedly connected to the housing 333. In practice, there are various ways to fixedly install it. In this embodiment, the motor 31 can be fixedly installed on the housing 333 through a flange 32. Specifically, end caps 331 are provided at both the upper and lower ends of the housing 333, and the end caps 331 are fixedly connected to the flange 32, so that the stroke adjuster 33 can achieve the function of stroke adjustment.

[0045] The specific adjustment principle is as follows;

[0046] A base 332 that can be adjustably fixed at any position on the straight track is movably connected to the straight track. To achieve the adjustability of the base 332, an adjusting rod 334 that is threadedly connected to the housing 333 is provided in the housing 333. One end of the adjusting rod 334 is rotatably connected to the base 332, and the other end extends to the outside of the housing 333. In practice, a connecting member 3322 is rotatably connected to the base 332. The connecting member 3322 is arranged eccentrically and parallel to the axis of the output shaft of the motor 31. Thus, when the motor 31 drives the housing 333 to rotate, the connecting member 3322 can have a stroke with different rotation radii. The adjustment size of this stroke depends on the change amount of the rotation angle of the accelerator pedal 9.

[0047] Please refer to Figure 8, the connection method between the pressing plate assembly 8 and the support rod 4 is shown in the figure. The pressing plate assembly 8 includes a pressing plate 82, and the lower end surface of the pressing plate 82 forms a surface contour that fits the upper surface of the accelerator pedal 9; an adjusting plate 81, one end of the adjusting plate 81 is fixedly connected to the pressing plate 82, and the other end is connected to the output end of the connecting rod assembly with its steering angle adjustable. One end of the adjusting plate 81 is provided with a double-layer plate structure, namely an upper plate 811 and a lower plate 812. The upper plate 811 and the lower plate 812 form an accommodation hole 814 for accommodating the end contour size of the support rod 4 in a certain area position. By using the relative fastening force of the bolt 813 to fix the upper plate 811 and the lower plate 812, the adjusting plate 81 can adjust the connection tightness of the support rod 4. When the adjusting plate 811 needs to drive the pressing plate 82 to rotate to a certain position, only the relative position between it and the support rod 4 needs to be rotated and fastened by the bolt 813 to achieve it.

[0048] Please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 9 , the state diagram of the pressing plate assembly 8 pressing the accelerator pedal 9 and the process state formed by the rotation of the support rod 4 output to the pressing plate assembly 8 are shown in the above figure. Specifically as follows;

[0049] When the accelerator pedal 9 is not under force, its angle is A. When the accelerator pedal 9 is under force and reaches the maximum rotation angle, its angle is B. Thus, it can be calculated that the maximum rotation angle of the accelerator pedal 9 is α = A - B. In order to enable the pressing plate assembly 8 to output the same rotation stroke to the accelerator pedal 9, the connecting rod assembly needs to output a force with an α rotation angle to the pressing plate assembly 8, and this force is obtained by adjusting the power assembly. For this reason, the present invention provides a method for testing an accelerator pedal, and the testing method of the accelerator pedal will be described in detail below in combination with specific embodiments.

[0050] The method includes:

[0051] Obtain a stroke information, and the stroke information is the change amount of the rotation angle of the accelerator pedal, which can be understood by those skilled in the art as α described in the above description;

[0052] Obtain an output stroke information according to the stroke information. The power assembly obtains an output stroke through this output stroke information. The output stroke has an initial stroke point and a final stroke point. The initial stroke point to the final stroke point constitutes the first stroke of the power assembly, and the final stroke point to the initial stroke point constitutes the second stroke of the power assembly. The first stroke and the second stroke constitute a cycle stroke of the output stroke. Please return to Figure 9In the [device / system], the power component converts the output stroke into the rotation of the support rod 4 through force transmission. Those skilled in the art can understand that the initial stroke point is converted into the position point of the support rod 4 at R1, and the end stroke point is converted into the position point of the support rod 4 at R2. The angular change amount of the support rod 4 between the two points is α;

[0053] Obtain an assembly position, which is the spatial position of the pressure plate 82 when the power component is at the initial stroke point, the pressure plate 82 is in contact with the accelerator pedal 9 and there is no external force acting on it;

[0054] The power component applies a stroke with at least one cycle to the pressure plate 82 through the linkage mechanism. Here, those skilled in the art can understand that when the pressure plate 82 presses the accelerator pedal 9 and the accelerator pedal 9 returns to the initial position, it is one cycle of the stroke. Generally, a complete test needs to implement up to tens of thousands of cycles. In this embodiment, the specific number of cycles is not limited.

[0055] Furthermore,

[0056] The steps of obtaining the stroke information include:

[0057] Attach the pressure plate 82 to the accelerator pedal 9 without applying external force, and obtain the first position information of the pressure plate 82. The first position information is the point generated on the contact surface between the pressure plate 82 and the accelerator pedal 9;

[0058] Apply an external force to the pressure plate 82 until the accelerator pedal 9 reaches the maximum rotation angle, and obtain the second position information of the pressure plate 82. The second position information is a point generated after the point generated by the first position information undergoes displacement in an arc path under the application of an external force by the pressure plate;

[0059] Determine the point generated by the first position information as the first information point, and the first information point is the initial position where the pressure plate 82 contacts the accelerator pedal 9 without applying external force; determine the point generated by the second position information as the second information point, and the second information point is the end position after the accelerator pedal 9 reaches the maximum rotation angle;

[0060] Determine the stroke information according to the first information point and the second information point. The stroke information is the angular change amount generated from the first information point to the second information point, which is α as described above.

[0061] In practice, first determine α, and then adjust the output stroke of the power component. In order to conveniently and intuitively show the angular position of the pressure plate assembly 8, an angle gauge 83 is provided on the pressure plate assembly 8. The adjustment process is as follows;

[0062] 1. Confirm α:

[0063] Assemble the accelerator pedal 9 to the work station. At this time, adjust the tightness between the adjusting rod 4 and the adjusting plate 8 so that the adjusting plate 8 can rotate on the adjusting rod 4. When the pressing plate 82 fits on the surface of the accelerator pedal 9, record the angular position of the pressing plate 82 at this time through the angle gauge 83, denoted as A; when the pressing plate 82 applies force to the accelerator pedal 9 and causes the accelerator pedal 9 to have the maximum rotation angle, record the angular position of the pressing plate 82, denoted as B; thus, the maximum rotation angle of the accelerator pedal 9 is obtained as α.

[0064] II. Adjust the output stroke of the power assembly:

[0065] Fix the relative position of the adjusting plate 81 and the adjusting rod 4, and make the track in the housing 333 arranged vertically. Record the angular position of the pressing plate 82 at this time through the angle gauge 83, denoted as A1; adjust the base 332 in the vertical position by rotating the adjusting rod 334. Here, those skilled in the art can understand that by adjusting the position of the base 332 on the track, the relative position of the connecting piece 3322 in the base 332 with respect to the output shaft of the motor 31 can be realized, and the rotation stroke can be adjusted by changing the radius; during the adjustment process, rotate the housing 333. At this time, the pressing plate 82 obtains a new angular position, and obtain the angular position of the pressing plate 82 through the angle gauge, denoted as B1. During the adjustment process, it is necessary to satisfy that when the base 332 is in two directions in the vertical position, that is, when the base 332 is in the vertical state and still in the vertical state after rotating 180°, the corresponding pressing plate 82 has two angular positions (A1 and B1 respectively), and at this time A1 - B1 = α, so as to realize the adjustment of the output stroke, and at the same time, the output stroke is the rotation stroke of the pressing plate assembly 8 and the accelerator pedal 9.

[0066] III. Assembly:

[0067] As described above, the power assembly has obtained the required output stroke, and the associated adjusting rod 4 has a rotation period of α. At this time, place the housing 333 vertically, and make the adjusting rod 4 at the initial stroke point R1. Assemble the accelerator pedal 9 to the work station, and adjust the rotational position of the pressing plate 82 relative to the adjusting rod 4 so that the pressing plate 82 fits on the surface of the accelerator pedal 9 without applying external force, and fix the relative position of the adjusting plate 81 and the adjusting rod 4. In this way, the pressing plate assembly 8 has completed the assembly. The number of test cycles after assembly depends on the specific situation, and this embodiment does not make specific limitations on it.

[0068] The embodiments described above are only used to describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
