Description

Technical Field

[0001] The invention relates to the technical field of automobile detection, in particular to an automobile pedal motor durability test device. Background Art

[0002] With the rapid development of the transportation industry today, more and more vehicles appear in people's daily lives. Cars have become the mainstream means of transportation. The continuous improvement, updating and optimization of auto parts have become inevitable in the automotive industry. The pedal is one of the main parts of the car, and its reliability directly affects the normal use of the car. Therefore, the corresponding durability test must be done before the pedal is used to ensure the sensitivity and durability of the pedal.

[0003] The pedal durability test not only examines the strength of the pedal itself, but also verifies its service life, and whether unacceptable deformation, sticking, abnormal noise and other defects will occur during its service life. Since different user groups have significantly different forces applied to the pedal, it is impossible to adjust the amount of force applied to the pedal, and thus it is impossible to simulate the operating habits of different user groups, which affects the pedal durability test results. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A vehicle pedal motor durability test device, comprising a platform, a guide rod is fixedly connected to the top of the platform, the number of the guide rods is multiple, the multiple guide rods are located at the top corner of the platform, the top of the guide rod is fixedly connected to the top plate, the top of the top plate is fixedly connected to the top of the hydraulic cylinder, and the output end of the hydraulic cylinder passes through the top plate;

[0005] A driving assembly, which is fixedly mounted on the output end of the hydraulic cylinder and is slidably connected to the guide rod;

[0006] The fixed component is fixedly installed on the top of the platform. There are multiple fixed components, and the multiple fixed components are symmetrically staggered. By setting multiple fixed components, multiple pedals can be tested at the same time, which can greatly improve the detection efficiency. Compared with testing the pedals one by one, this method can complete the detection of more pedals in the same time, thereby shortening the detection cycle. It is especially suitable for the quality inspection link in large-scale production, and the fixed components are alternately set to save working space;

[0007] The fixing assembly includes a fixing block, a square plate is fixedly connected to the top of the fixing block, a base is fixedly connected to the top of the square plate, a limiting hole is arranged on the outer side of the base, the limiting hole is fan-shaped, and the bottom side of the limiting hole is higher than the limiting height of the limiting cylinder, a rotating rod is fixedly connected to the inside of the limiting hole, and a support arm is fixedly connected to the outer side of the rotating rod, and the object to be measured is placed on the fixing part, and the motor is connected to the external power supply to work, and the motor drives the limiting cylinder to rotate. Due to the threaded connection between the limiting cylinder and the base, the upper and lower position relationship of the limiting cylinder in the base can be driven, and then the compression degree of the compression spring can be adjusted, that is, when the object to be measured is subjected to force, the support arm rotates with the rotating rod, The resistance of the compression spring can be adjusted. Since the forces applied to the pedal by people of different genders, ages and physical conditions are significantly different, by adjusting the degree of compression of the compression spring, the downward force of the pedal by different groups of people can be simulated, which can make the durability test data more accurate. At the same time, by reasonably adjusting the magnitude of the force, various forces that the pedal may encounter in long-term actual use can be simulated in a relatively short period of time, thereby effectively shortening the test cycle and improving the test efficiency. One end of the support arm away from the rotating rod is fixedly connected to a fixing part, and a compression spring is arranged at the bottom of the support arm. The bottom of the compression spring is fixedly connected to a limiting cylinder, and the limiting cylinder is rotatably connected to the base.

[0008] Preferably, there are two fixed blocks, which are located at the two ends of the bottom of the square plate. The bottom of the square plate is fixedly connected to a motor, which is located in the middle of the two fixed blocks. The motor is fixedly connected to the limit cylinder, and a threaded groove is provided on the outer side of the limit cylinder. The limit hole is set in an L shape. A sliding rod is fixedly connected to the side of the support arm close to the compression spring. The sliding rod penetrates the compression spring. When the hydraulic cylinder works, it drives the driving assembly to move downward on the guide rod, thereby applying force to the pedal. The pedal is driven by the extrusion force to rotate the support arm inside the limit hole, and the support arm drives the sliding rod to slide downward inside the limit cylinder. At the same time, the cylinder slides inside the slide groove. Through the guidance between the cylinder and the slide groove, it can ensure that the pedal rotates according to a predetermined trajectory to limit the pedal The freedom of movement can only be achieved within the designed rotation plane, avoiding irregular movements such as left-right swinging or up-and-down deviation of the pedal, thereby ensuring that the trajectory of each pedal rotation is highly consistent, and the guide can effectively reduce the vibration and shaking of the pedal during rotation, reduce the vibration caused by uneven friction or loose components, and keep the pedal stable during rotation, improve the detection accuracy, and make the detection data more reliable. The slide rod passes through the compression spring and is slidably connected to the inner wall of the limit cylinder. An arc plate is fixedly connected to the outside of the base. There are two arc plates, which are symmetrically arranged with the support arm as the center. A slide groove is provided on the side of the arc plate close to the support arm, and a cylinder is fixedly connected to the side of the support arm close to the slide groove, and the cylinder is located inside the slide groove.

[0009] Preferably, the fixing member includes a fixing frame, which is fixedly connected to the end of the support arm away from the rotating rod, and a frame is fixedly connected to the outer side of the fixing frame, and the frame is symmetrically arranged with the fixing frame as the center. When the object to be tested is placed on the fixing frame, the spring plate is deformed by force, and the outer side of the object to be tested can be fixed by the spring plate arranged at the corner of the fixing frame to prevent the pedal from moving during the detection process. By utilizing the elastic properties of the spring plate, when the pedal is impacted by external force or vibrates during the detection process, the elasticity of the spring plate can absorb part of the energy, reduce the impact on the pedal, and facilitate installation and disassembly. A through hole is opened on the outer side of the fixing frame, and the through holes are symmetrically arranged on the fixing frame with the frame as the center. The inner wall of the through hole is fixedly connected with a spring plate, and the spring plate is located at the corner of the fixing frame. A circular hole is opened on the top of the frame.

[0010] Preferably, the driving assembly includes a moving plate, the moving plate is fixedly connected to the output end of the hydraulic cylinder, the moving plate is slidably connected to the guide rod, a square groove is opened in the middle of the bottom of the moving plate, and a positioning plate is fixedly connected inside the square groove; the bottom of the positioning plate is inclined, and a notch is opened inside the positioning plate, and the notch is parallel to the bottom inclined surface of the positioning plate. During the driving of the car, when the pedal is pressed, the rotation of the pedal causes the center of gravity position of the driver's foot applying force to the pedal to change, that is, the center of gravity is close to one end of the limb after the pedal is pressed. After the pedal is fixed, the magnitude of the force is adjusted by the motor, and the hydraulic cylinder drives the moving plate to move downward on the outer side of the guide rod, so that the roller contacts the top of the pedal. As the hydraulic cylinder continues to move downward, the object to be measured is acted upon by the force, and the support arm is subjected to the force and rotates with the rotating rod, generating an extrusion force between the pedal and the roller, and as the support arm rotates, the return spring is compressed by the force, so that the roller drives the U-shaped plate to move inside the notch, and at this time the roller is located near the pedal The end near the support arm can more accurately simulate the mechanical state during actual operation, so that the test data is more in line with actual usage and provide a reliable basis for subsequent analysis and evaluation. At the same time, a reasonable distribution of the center of gravity can enable the pedal to apply a more uniform and stable force to the test equipment components in contact with it during the test process, which helps to reduce the excessive pressure or impact force on the local part of the test equipment, reduce the possibility of equipment damage, and extend the service life of the test equipment. At the same time, it can also ensure the accuracy and reliability of the test equipment and avoid deviations in test results caused by equipment damage. The inside of the notch is slidably connected to a U-shaped plate, and the outside of the U-shaped plate is fixedly connected to a return spring. The end of the return spring away from the U-shaped plate is fixedly connected to the notch, and the open end of the U-shaped plate is rotatably connected to a roller. The bottom of the inner wall of the U-shaped plate is parallel to the notch, and the positioning plate is located directly above the fixed assembly. There are multiple positioning plates, and the multiple positioning plates are symmetrically staggered. The roller and the top of the fixing are located on the same vertical plane.

[0011] The present invention provides a vehicle pedal motor durability test device, which has the following beneficial effects:

[0012] 1. The automobile pedal motor durability test device can simulate the force exerted by different groups of people on the pedal by adjusting the compression degree of the compression spring, so as to make the durability test data more accurate. At the same time, by reasonably adjusting the force, it can simulate various forces that the pedal may encounter in long-term actual use in a relatively short time, thereby effectively shortening the test cycle and improving the test efficiency.

[0013] 2. The automobile pedal motor durability test device can ensure that the pedal rotates according to a predetermined trajectory through the guidance between the cylinder and the slide groove, limit the degree of freedom of the pedal so that it can only move within the designed rotation plane, and avoid irregular movements such as left and right swinging or up and down deviation of the pedal, thereby ensuring that the trajectory of each pedal rotation is highly consistent.

[0014] 3. The automobile pedal motor durability test device can fix the outer side of the object to be tested by means of a spring plate arranged at the corner of the fixed frame to prevent the pedal from moving during the test. By utilizing the elastic properties of the spring plate, when the pedal is impacted by an external force or vibrates during the test, the elasticity of the spring plate can absorb part of the energy, thereby reducing the impact on the pedal and facilitating installation and disassembly.

[0015] 4. The automobile pedal motor durability test device can make the pedal apply more uniform and stable force to the test equipment parts in contact with it during the test process through reasonable center of gravity distribution, which helps to reduce excessive pressure or impact force on the local part of the test equipment, reduce the possibility of equipment damage, and extend the service life of the test equipment. At the same time, it can also ensure the accuracy and reliability of the test equipment and avoid deviation in test results caused by equipment damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: a vehicle pedal motor durability test device, comprising a platform 1, a guide rod 2 is fixedly connected to the top of the platform 1, there are multiple guide rods 2, the multiple guide rods 2 are located at the top corners of the platform 1, a top plate 3 is fixedly connected to the top of the guide rod 2, a hydraulic cylinder 4 is fixedly connected to the top of the top plate 3, and the output end of the hydraulic cylinder 4 passes through the top plate 3;

[0029] A driving assembly 5, which is fixedly mounted on the output end of the hydraulic cylinder 4 and is slidably connected to the guide rod 2;

[0030] A fixing component 6, the fixing component 6 is fixedly installed on the top of the platform 1, and there are multiple fixing components 6, and the multiple fixing components 6 are symmetrically staggered. By setting multiple fixing components 6, multiple pedals can be tested at the same time, which can greatly improve the testing efficiency. Compared with testing the pedals one by one, this method can complete the testing of more pedals in the same time, thereby shortening the testing cycle, which is particularly suitable for the quality testing link in large-scale production, and the fixing components 6 are alternately arranged to save working space;

[0031] The fixing assembly 6 comprises a fixing block 61, a square plate 62 is fixedly connected to the top of the fixing block 61, a base 63 is fixedly connected to the top of the square plate 62, a limiting hole 64 is arranged on the outer side of the base 63, the limiting hole 64 is fan-shaped, and the bottom side of the limiting hole 64 is higher than the limiting height of the limiting cylinder, a rotating rod 611 is fixedly connected to the inside of the limiting hole 64, and a supporting arm 65 is fixedly connected to the outer side of the rotating rod 611, and the object to be measured is placed on the fixing member 66, and the motor 610 is connected to an external power supply to work, and the motor 610 drives the limiting cylinder 69 to rotate. Since the limiting cylinder 69 and the base 63 are threadedly connected, the upper and lower position relationship of the limiting cylinder 69 in the base 63 can be driven, and then the compression degree of the compression spring 68 can be adjusted, that is, when the object to be measured is subjected to the action of force, When the support arm 65 rotates with the rotating rod 611, the resistance of the compression spring 68 can be adjusted. Since the forces applied to the pedal by people of different genders, ages and physical conditions are significantly different, by adjusting the compression degree of the compression spring 68, the downward force of the pedal by different groups of people can be simulated, which can make the durability test data more accurate. At the same time, by reasonably adjusting the magnitude of the force, various forces that the pedal may encounter in long-term actual use can be simulated in a relatively short period of time, thereby effectively shortening the test cycle and improving the test efficiency. One end of the support arm 65 away from the rotating rod 611 is fixedly connected to a fixing part 66, and a compression spring 68 is arranged at the bottom of the support arm 65. The bottom of the compression spring 68 is fixedly connected to a limiting cylinder 69, and the limiting cylinder 69 is rotatably connected to the base 63.

[0032] There are two fixed blocks 61, which are located at the two ends of the bottom of the square plate 62. The bottom of the square plate 62 is fixedly connected with a motor 610, which is located in the middle of the two fixed blocks 61. The motor 610 is fixedly connected to the limiting cylinder 69. The outer side of the limiting cylinder 69 is provided with a threaded groove. The limiting hole 64 is L-shaped. The side of the support arm 65 close to the compression spring 68 is fixedly connected with a slide bar 67. The slide bar 67 penetrates the compression spring 68. The hydraulic cylinder 4 works to drive the drive assembly 5 to move downward on the guide rod 2, thereby applying force to the pedal. The pedal is squeezed and drives the support arm 65 to rotate inside the limiting hole 64. The support arm 65 drives the slide bar 67 to slide downward inside the limiting cylinder 69. At the same time, the cylinder 614 slides inside the slide groove 613. The guidance between the cylinder 614 and the slide groove 613 can ensure that the pedal moves along a predetermined trajectory. Rotation limits the freedom of the pedal so that it can only move within the designed rotation plane, avoiding irregular movements such as left and right swinging or up and down deviation of the pedal, thereby ensuring that the trajectory of each pedal rotation is highly consistent, and the guide can effectively reduce the vibration and shaking of the pedal during rotation, reduce the vibration caused by uneven friction or loose components, so that the pedal remains stable during rotation, improves the detection accuracy, and makes the detection data more reliable. The slide bar 67 passes through the compression spring 68 and is slidably connected to the inner wall of the limit tube 69. An arc plate 612 is fixedly connected to the outer side of the base 63. There are two arc plates 612. The two arc plates 612 are symmetrically arranged with the support arm 65 as the center. A slide groove 613 is opened on the side of the arc plate 612 close to the support arm 65, and a cylinder 614 is fixedly connected to the side of the support arm 65 close to the slide groove 613. The cylinder 614 is located inside the slide groove 613.

[0033] The second embodiment is based on the first embodiment. Figures 7 and 8 As shown, the fixing member 66 includes a fixing frame 661, and the fixing frame 661 is fixedly connected to the end of the support arm 65 away from the rotating rod 611. The outer side of the fixing frame 661 is fixedly connected to a frame 665, and the frame 665 is symmetrically arranged with the fixing frame 661 as the center. When the object to be tested is placed on the fixing frame 661, the spring plate 663 is deformed by force. The spring plate 663 arranged at the corner of the fixing frame 661 can fix the outer side of the object to be tested to prevent the pedal from moving during the detection process. The elastic performance of 63, when the pedal is impacted by external force or vibrates during the detection process, the elasticity of the spring plate 663 can absorb part of the energy, reduce the impact on the pedal, and facilitate installation and disassembly. A through hole 662 is provided on the outer side of the fixed frame 661, and the through hole 662 is symmetrically arranged on the fixed frame 661 with the frame 665 as the center. The inner wall of the through hole 662 is fixedly connected with the spring plate 663, and the spring plate 663 is located at the corner of the fixed frame 661. A round hole 664 is provided on the top of the frame 665.

[0034] The third embodiment is based on the first and second embodiments. Figures 9 and 10 As shown, the driving assembly 5 includes a moving plate 51, which is fixedly connected to the output end of the hydraulic cylinder 4, and is slidably connected to the guide rod 2. A square groove 52 is provided in the middle of the bottom of the moving plate 51, and a positioning plate 53 is fixedly connected inside the square groove 52. The bottom of the positioning plate 53 is inclined, and a notch 54 is provided inside the positioning plate 53. The notch 54 is parallel to the bottom inclined surface of the positioning plate 53. During the driving process of the car, when the pedal is pressed, the rotation of the pedal causes the center of gravity position of the driver's foot applying force to the pedal to change. That is, after the pedal is pressed, the center of gravity is close to one end of the limb. After the pedal is fixed, the magnitude of the force is adjusted by the motor 610. At this time, the hydraulic cylinder 4 works to drive the movable plate 51 to move downward on the outside of the guide rod 2, so that the roller 57 contacts the top of the pedal. As the hydraulic cylinder 4 continues to move downward, the object to be measured is acted upon by the force, and the support arm 65 is forced to rotate with the rotating rod 611, and an extrusion force is generated between the pedal and the roller 57. As the support arm 65 rotates, the return spring 55 is compressed by the force, so that the roller 57 drives the U-shaped plate 56 to move inside the notch 54. The roller 57 is located at one end of the pedal close to the support arm 65, which can more accurately simulate the mechanical state during real operation, so that the detection data is more in line with the actual use situation, providing a reliable basis for subsequent analysis and evaluation. At the same time, the reasonable distribution of the center of gravity can make the pedal apply a more uniform and stable force to the detection equipment components in contact with it during the detection process, which helps to reduce the excessive pressure or impact force on the local part of the detection equipment, reduce the possibility of equipment damage, and extend the service life of the detection equipment. At the same time, it can also ensure the accuracy and reliability of the detection equipment and avoid the deviation of the detection result caused by equipment damage. The inside of the notch 54 is slidably connected with a U-shaped plate 56, and the outer side of the U-shaped plate 56 is fixedly connected with a return spring 55. The end of the return spring 55 away from the U-shaped plate 56 is fixedly connected to the notch 54, and the open end of the U-shaped plate 56 is rotatably connected with a roller 57. The bottom of the inner wall of the U-shaped plate 56 is parallel to the notch 54. The positioning plate 53 is located directly above the fixed component 6. There are multiple positioning plates 53, and the multiple positioning plates 53 are symmetrically staggered. The roller 57 and the top of the fixing member 66 are located on the same vertical plane.

[0035] When in use, the object to be measured is placed on the fixed frame 661, and the spring plate 663 is deformed by the force. The outer side of the object to be measured can be fixed by the spring plate 663 arranged at the corner of the fixed frame 661. The motor 610 is connected to an external power supply to work, and the motor 610 drives the limit cylinder 69 to rotate. Since the limit cylinder 69 and the base 63 are threadedly connected, the upper and lower position relationship of the limit cylinder 69 in the base 63 can be driven, and then the compression degree of the compression spring 68 can be adjusted. That is, when the object to be measured is subjected to the force, the support arm 65 rotates with the rotating rod 611, and the resistance of the compression spring 68 can be adjusted.

[0036] The hydraulic cylinder 4 works to drive the movable plate 51 to move downward on the outside of the guide rod 2, so that the roller 57 contacts the top of the pedal. As the hydraulic cylinder 4 continues to move downward, the object to be tested is acted upon by a force, and the support arm 65 is subjected to the force to rotate along with the rotating rod 611, and an extrusion force is generated between the pedal and the roller 57. As the support arm 65 rotates, the return spring 55 is compressed, so that the roller 57 drives the U-shaped plate 56 to move inside the slot 54. At this time, the roller 57 is located at one end of the pedal close to the support arm 65, which can more accurately simulate the mechanical state during actual operation, so that the detection data is more in line with actual usage.

[0037] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
