Description

Technical Field

[0001] This application relates to the field of vehicle braking technology, and in particular to a vehicle braking system assembly testing device. Background Technology

[0002] During vehicle production or maintenance, it is often necessary to test the vehicle's braking system assembly. During testing, a drive mechanism is typically used to simulate a human foot, causing the output end of the drive mechanism to move the input end of the vehicle's braking system assembly, thus triggering the braking process. During braking, personnel can check various indicators of the vehicle's braking system assembly, such as the noise emitted by the braking system assembly, to determine whether the braking process meets requirements.

[0003] However, in related technologies, the testing of vehicle braking system assemblies is not accurate enough, and there are often cases where the test results are qualified, but the actual use results are unqualified. Utility Model Content

[0004] This application provides a vehicle braking system assembly testing device that can improve the accuracy of testing.

[0005] This application provides a vehicle braking system assembly testing device, which includes a base and a loading mechanism. The base is configured to mount the vehicle braking system assembly, and the loading mechanism is movably disposed on the base. The loading mechanism includes a drive component, the output end of which is configured to connect to the input end of the vehicle braking system assembly, and the output end of the drive component is configured to drive the input end of the vehicle braking system assembly to move relative to the base.

[0006] The vehicle braking system assembly testing device provided in this application allows the loading mechanism to be movably mounted on the base, enabling the adjustment of the loading mechanism's position relative to the base. This, in turn, allows the adjustment of the position of the driving component relative to the base. Since the vehicle braking system assembly is mounted on the base and the driving component's position relative to the base is adjustable, the driving component's position relative to the vehicle braking system assembly can be adjusted. This allows the driving component to move the input end of the vehicle braking system assembly in various positions, triggering the braking process. The movement of the driving component's output end more closely matches the movement of a person's feet during vehicle operation, making the testing process more comprehensive and improving its accuracy.

[0007] In some possible implementations of this application, the loading mechanism further includes a movable component that is slidably connected to the base, and a driving component disposed on the movable component. The direction in which the movable component slides relative to the base has a component along the vehicle width direction. The driving component has a first posture and a second posture. In the first posture, the movable component is disposed opposite to the vehicle braking system assembly along the vehicle length direction. In the second posture, the movable component is offset from the vehicle braking system assembly along the vehicle length direction.

[0008] In this way, in the first posture, the driving component can trigger the braking process. After the braking process ends, the moving component slides relative to the base, and the driving component switches to the second posture. The driving component obstructs the vehicle braking system assembly less, so personnel can easily operate the vehicle braking system assembly, which is beneficial to improving the convenience of the testing process. Personnel can operate the braking system, for example, by stepping on the input end of the vehicle braking system assembly.

[0009] In some possible implementations of this application, the movable component includes a first movable module and a second movable module. The first movable module is slidably connected to the base, and the second movable module is slidably connected to the first movable module, with the direction of relative sliding perpendicular to the vehicle width direction. The drive component is disposed on the second movable module.

[0010] By sliding the first movable module to the base, with the relative sliding direction having a component along the vehicle width direction, the drive component can switch between a first posture and a second posture, allowing personnel to easily operate the vehicle braking system assembly. Furthermore, different types of vehicle braking system assemblies often have different dimensions, and after installation on the base, the relative positions of the input ends of different types of vehicle braking system assemblies to the base often differ, primarily varying in the direction perpendicular to the vehicle width direction. By sliding the second movable module to the first movable module, with the relative sliding direction perpendicular to the vehicle width direction, the drive component can translate relative to the base along at least one direction perpendicular to the vehicle width direction. This allows the drive component to move to the input ends of different vehicle braking system assemblies, triggering different types of vehicle braking system assemblies, thus making the vehicle braking system assembly testing device highly adaptable.

[0011] In some possible implementations of this application, the second active module includes a first active component and a second active component. The first active component is slidably connected to the first active module, and the second active component is slidably connected to the first active component. The sliding direction of the second active component relative to the first active component, the sliding direction of the first active component relative to the first active module, and the vehicle width direction are all perpendicular to each other. The driving component is disposed on the second active component.

[0012] In this way, the drive component can translate relative to the base in three perpendicular directions, and the drive component can be adjusted in a more flexible position relative to the base, so that the movement of the output end of the drive component can better simulate the human foot, and also make the vehicle braking system assembly test device adaptable to more types of vehicle braking system assemblies.

[0013] In some possible implementations of this application, the direction in which the first movable member slides relative to the first movable module is parallel to the length direction of the vehicle.

[0014] Thus, the sliding direction of the second movable component relative to the first movable component is parallel to the vehicle height direction. Compared to the sliding direction of the first movable component relative to the first movable module being parallel to the vehicle height direction, the sliding direction of the second movable component relative to the first movable component is parallel to the vehicle length direction. In this application, the number of components that need to translate relative to the base along the vehicle height direction is smaller. It is understood that with the method where the sliding direction of the first movable component relative to the first movable module is parallel to the vehicle height direction, during the sliding process of the first movable component relative to the first movable module, the first movable component, the second movable component, and the driving component all need to translate relative to the base along the vehicle height direction. However, in the method of this application, the second movable component and the driving component can jointly translate relative to the base along the vehicle height direction, and the first movable component does not need to translate relative to the base along the vehicle height direction. It is understood that the translation of components relative to the base along the vehicle height direction requires overcoming gravity. In this application, the number of components that need to translate relative to the base along the vehicle height direction is smaller, and the gravity that needs to be overcome during movement is also smaller, which helps to reduce energy consumption and improve the stability of movement.

[0015] In some possible implementations of this application, the loading mechanism further includes a movable component that is slidably connected to the base, and a driving component disposed on the movable component. The direction in which the movable component slides relative to the base is perpendicular to the vehicle width direction.

[0016] Different types of vehicle braking system assemblies often have different dimensions. After being installed on the base, the relative positions of the input ends of different types of vehicle braking system assemblies to the base are also often inconsistent, mainly varying in the direction perpendicular to the vehicle width direction. By making the moving part slide against the base, with the relative sliding direction perpendicular to the vehicle width direction, the drive part can be translated relative to the base along at least one direction perpendicular to the vehicle width direction. This allows the drive part to move to the input end of different vehicle braking system assemblies, triggering different types of vehicle braking system assemblies, thus making the vehicle braking system assembly testing device highly adaptable.

[0017] In some possible implementations of this application, the movable components include a third movable module and a fourth movable module. The third movable module is slidably connected to the base, and the fourth movable module is slidably connected to the third movable module. The sliding direction of the fourth movable module relative to the third movable module, the sliding direction of the third movable module relative to the base, and the vehicle width direction are all perpendicular to each other. The drive component is disposed on the fourth movable module.

[0018] By making the direction in which the fourth active module slides relative to the third active module, the direction in which the third active module slides relative to the base, and the vehicle width direction perpendicular to each other, the drive component is set on the fourth active module. This allows the drive component to be adjusted more flexibly in a plane perpendicular to the vehicle width direction, enabling the output end movement of the drive component to better simulate human feet. It also allows the vehicle braking system assembly testing device to adapt to more types of vehicle braking system assemblies.

[0019] In some possible implementations of this application, the direction in which the third active module slides relative to the base is parallel to the length direction of the vehicle.

[0020] Thus, the sliding direction of the fourth active module relative to the third active module is parallel to the vehicle height direction. While the sliding direction of the third active module relative to the base is parallel to the vehicle height direction, the sliding direction of the fourth active module relative to the third active module is parallel to the vehicle length direction. In this application, the number of components that need to translate relative to the base along the vehicle height direction is smaller. It is understood that with the method where the sliding direction of the third active module relative to the base is parallel to the vehicle height direction, during the sliding process of the third active module relative to the base, the third active module, the fourth active module, and the drive component all need to translate relative to the base along the vehicle height direction. However, in the method of this application, the fourth active module and the drive component can jointly translate relative to the base along the vehicle height direction, and the third active module does not need to translate relative to the base along the vehicle height direction. It is understood that the translation of components relative to the base along the vehicle height direction requires overcoming gravity. In this application, the number of components that need to translate relative to the base along the vehicle height direction is smaller, and the gravity that needs to be overcome during movement is also smaller, which helps to reduce energy consumption and improve the stability of movement.

[0021] In some possible implementations of this application, the drive component includes a mounting part and a movable part. The mounting part is rotatably connected to the movable part, and the axis of rotation of the mounting part relative to the movable part is parallel to the vehicle width direction. The movable part is slidably connected to the mounting part, and the direction of sliding of the movable part relative to the mounting part is perpendicular to the vehicle width direction. The movable part includes the output end of the drive component.

[0022] By making the axis of rotation of the mounting part relative to the moving part parallel to the vehicle width direction, and the direction of sliding of the moving part relative to the mounting part perpendicular to the vehicle width direction, the angle between the direction of sliding of the moving part relative to the mounting part and the horizontal direction changes during the rotation of the mounting part relative to the moving part. This allows the drive component to simulate human legs at different tilt angles, which helps to improve the accuracy of the test.

[0023] In some possible implementations of this application, the vehicle braking system assembly testing device further includes a sensing module, with a drive component connected to the sensing module and configured to adjust the output parameters of the drive component's output terminal based on the detection information from the sensing module. The sensing module includes components configured to detect at least one of the following: the displacement of the drive component's output terminal relative to the base, the force exerted by the drive component's output terminal on the input terminal of the vehicle braking system assembly, and the output hydraulic pressure of the vehicle braking system assembly.

[0024] In this way, the sensing module can detect the actual output parameters of at least one of the drive components and the vehicle braking system assembly. Based on the detection results, the drive component can adjust its own output parameters, forming a control closed loop. This makes the actual output parameters of the drive components and the vehicle braking system assembly closer to the set parameters, which helps improve the accuracy of the test. Furthermore, the detection results of the sensing module can also be used for fault diagnosis, facilitating the testing of vehicle braking system assemblies and the production and maintenance of vehicle braking system assemblies.

[0025] In some possible implementations of this application, the driving component includes a driving member and a loading member, the loading member being detachably connected to the output end of the driving member, and the loading member being configured to be detachably connected to the input end of the vehicle braking system assembly. The vehicle braking system assembly testing device also includes a sensing module, which includes a force sensor disposed between the output end of the loading member and the driving member.

[0026] By detachably connecting the loading element between the output end of the drive component and the input end of the vehicle braking system assembly, the loading element can be replaced. This allows personnel to select different loading elements for different types of vehicle braking system assemblies. The loading element, driven by the output end of the drive component, triggers the vehicle braking system assembly. Thus, the vehicle braking system assembly testing device can adapt to testing different types of vehicle braking system assemblies, exhibiting strong adaptability. Furthermore, a force sensor is positioned between the loading element and the output end of the drive component. The force sensor detects the force between the output end of the drive component and the loading element. The output end of the drive component triggers the vehicle braking system assembly through the loading element. The force between the output end of the drive component and the loading element is essentially equal to the force between the loading element and the vehicle braking system assembly. Therefore, the force sensor can detect the force exerted by the output end of the drive component on the input end of the vehicle braking system assembly. Moreover, compared to placing the force sensor between the input end of the vehicle braking system assembly and the loading component, in this application the force sensor is placed between the output end of the loading component and the drive component. The force sensor does not need to be replaced along with the loading component, and one force sensor can be used to test different types of vehicle braking system assemblies, which helps to reduce testing costs.

[0030] The technical solutions in this application will now be described clearly and in detail with reference to the accompanying drawings.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0035] During vehicle production or maintenance, it is often necessary to test the vehicle's braking system assembly. During testing, a drive mechanism is typically used to simulate a human foot, causing the output end of the drive mechanism to move the input end of the vehicle's braking system assembly, thus triggering the braking process. During braking, personnel can check various indicators of the vehicle's braking system assembly, such as the noise emitted by the braking system assembly, to determine whether the braking process meets requirements.

[0036] However, in related technologies, the testing of vehicle braking system assemblies is not accurate enough, and there are often cases where the test results are qualified, but the actual use results are unqualified.

[0037] The following analysis explains why vehicle braking system assembly testing is not accurate enough in related technologies: During actual vehicle operation, human feet may trigger the vehicle braking system assembly in various forms of movement. However, in related technologies, both the drive mechanism and the vehicle braking system assembly are fixedly mounted on the frame. The relative posture between the input ends of the drive mechanism and the vehicle braking system assembly cannot be adjusted. The movement forms in which the drive mechanism triggers the vehicle braking system assembly are relatively simple, resulting in insufficient testing. The drive mechanism cannot simulate the various movement forms of human feet, leading to poor accuracy.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3This application provides a vehicle braking system assembly testing device, which includes a base 1 and a loading mechanism 2. The base 1 is configured to mount a vehicle braking system assembly 01. The loading mechanism 2 is movably disposed on the base 1 and includes a drive component 21. The output end of the drive component 21 is configured to connect to the input end of the vehicle braking system assembly 01, and the output end of the drive component 21 is configured to drive the input end of the vehicle braking system assembly 01 to move relative to the base 1.

[0039] The vehicle braking system assembly testing device provided in this application embodiment allows the loading mechanism 2 to be movably disposed on the base 1, enabling the position of the loading mechanism 2 relative to the base 1 to be adjusted. This, in turn, allows the position of the drive component 21 relative to the base 1 to be adjusted. The vehicle braking system assembly 01 is mounted on the base 1, and the position of the drive component 21 relative to the base 1 can be adjusted. In other words, the position of the drive component 21 relative to the vehicle braking system assembly 01 can be adjusted. Thus, the drive component 21 can drive the input end of the vehicle braking system assembly 01 to move in various positions, triggering the braking process. The movement of the output end of the drive component 21 is more consistent with the movement of a person's feet during vehicle operation, making the testing process more comprehensive and improving the accuracy of the testing process.

[0040] Please refer to Figure 1 , Figure 2 and Figure 3 In this application embodiment, the type of vehicle braking system assembly 01 is not limited, and it can be an electro-hydraulic brake (EHB) system assembly, an electro-mechanical brake (EMB) system, or a vacuum-assisted braking system assembly, etc.

[0041] Please refer to Figure 1 and 4 In some embodiments of this application, the vehicle braking system assembly 01 is an electro-hydraulic braking system assembly or an electromechanical braking system assembly. The vehicle braking system assembly testing device also includes a power supply 5, which may be a programmable power supply. The power supply 5 is connected to the vehicle braking system assembly 01 and is used to supply power to the vehicle braking system assembly 01.

[0042] Please refer to Figure 1 , Figure 2 and Figure 3It is understood that the vehicle braking system assembly 01 includes a fixed component for fixed connection with the vehicle body or axle, and a moving component for transmitting braking force, the moving component being able to move relative to the vehicle body. The fixed component is, for example, the valve body of a hydraulic valve, which is a valve for flowing brake fluid; the moving component is, for example, a brake pedal, a push rod, or the piston of a hydraulic valve. In this embodiment, the vehicle braking system assembly 01 is mounted on the base 1, meaning the fixed component is fixedly connected to the base 1, while the moving component 22 is able to move relative to the base 1.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the vehicle braking system assembly testing device further includes a mounting plate 3. The thickness direction of the mounting plate 3 is parallel to the length direction of the vehicle. The mounting plate 3 is fixedly connected to the base 1, for example, by bolts. The vehicle braking system assembly 01 can be mounted on the base 1 by the mounting plate 3.

[0044] Please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the input terminal of the vehicle braking system assembly 01 can refer to a brake pedal or push rod, etc. The pedal or push rod moves relative to the base 1, triggering the braking process.

[0045] Please refer to Figure 1 and Figure 4 In some embodiments of this application, the vehicle braking system assembly testing device further includes a caliper 4 and an oil pipe. One end of the oil pipe is connected to the caliper 4, and the other end is connected to the oil outlet of the vehicle braking system assembly 01. The output end of the drive component 21 drives the input end of the vehicle braking system assembly 01 to move relative to the base 1, which enables the oil outlet of the vehicle braking system assembly 01 to output brake fluid to the oil pipe, thereby causing the brake fluid to drive the piston of the caliper 4 to move, so that the caliper 4 switches from the released state to the clamped state, triggering the braking process.

[0046] Please refer to Figure 1 and Figure 4 In this application embodiment, the driving component 21 can be implemented in various forms. In some embodiments of this application, the driving component 21 may include an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, etc. Taking an electric cylinder as an example, the output end of the electric cylinder can be directly or indirectly connected to the input end of the vehicle braking system assembly 01. During the operation of the electric cylinder, the output end of the electric cylinder, i.e., the piston rod, translates axially relative to the outer shell of the electric cylinder, pushing the brake pedal or push rod to trigger the braking process.

[0047] Please refer to Figure 1 and Figure 4In some embodiments of this application, the vehicle braking system assembly testing device further includes a controller 7, which is electrically connected to the drive component 21. The controller 7 can be used to control the output parameters of the drive component 21, such as the loading stroke, loading speed, loading force, and loading time of the drive component 21. The loading stroke refers to the movement stroke of the output end of the drive component 21 relative to the base 1. The loading speed refers to the movement speed of the output end of the drive component 21 relative to the base 1. The loading force refers to the force between the output end of the drive component 21 and the input end of the vehicle braking system assembly 01. The loading time refers to the time during which the output end of the drive component 21 applies a force to the input end of the vehicle braking system assembly 01.

[0048] Please refer to Figure 1 and Figure 4 The vehicle braking system assembly testing device provided in this application embodiment can be used to detect various indicators, such as the noise emitted by the vehicle braking system assembly 01 during braking. In some embodiments of this application, the vehicle braking system assembly testing device includes a detection module 6, which includes a microphone 61 facing the vehicle braking system assembly 01 and configured to detect the noise emitted by the vehicle braking system assembly 01. The vehicle braking system assembly 01 generally includes structures such as a motor, hydraulic valve, and gears. During braking, the high-frequency operation of the motor, the friction and impact between the piston and valve body of the hydraulic valve, and the gear transmission can all easily generate noise. The microphone 61 can collect the above noise.

[0049] Please refer to Figure 1 and Figure 4 In some embodiments of this application, the detection module 6 further includes a microphone bracket 64, the microphone 61 is fixed to the microphone bracket 64, and the microphone bracket 64 can be disposed on the base 1.

[0050] Please refer to Figure 1 and Figure 4 In some embodiments of this application, the detection module 6 further includes a data acquisition unit 62 and a computer 63. The data acquisition unit 62 is connected between the microphone 61 and the computer 63. The data acquisition unit 62 can convert the analog signal collected by the microphone 61 into a digital signal and transmit it to the computer 63 for analysis and processing.

[0051] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments of this application, the base 1 can be placed on a test platform. The base 1 has a first mounting hole 12, and the test platform has a second mounting hole. The first mounting hole 12 and the second mounting hole are arranged opposite each other along the vehicle height direction. The first mounting hole 12 is located above the second mounting hole. Fasteners are inserted into the first mounting hole 12 and the second mounting hole to secure the base 1 to the test platform. Generally, the vehicle height direction is the vertical direction.

[0052] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the loading mechanism 2 further includes a movable component 22, which is slidably connected to the base 1, and a driving component 21 is disposed on the movable component 22. The direction in which the movable component 22 slides relative to the base 1 has a component along the vehicle width direction. The driving component 21 has a first posture and a second posture. In the first posture, along the vehicle length direction, the movable component 22 is disposed opposite to the vehicle braking system assembly 01. In the second posture, along the vehicle length direction, the movable component 22 is offset from the vehicle braking system assembly 01.

[0053] In this way, in the first posture, the driving component 21 can trigger the braking process. After the braking process ends, the moving component 22 slides relative to the base 1, and the driving component 21 switches to the second posture. The driving component 21 has less obstruction to the vehicle braking system assembly 01, so that the personnel can easily operate the vehicle braking system assembly 01, which is conducive to improving the convenience of the testing process. The personnel's operation of the braking system is, for example, stepping on the input end of the vehicle braking system assembly 01.

[0054] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the direction in which the movable component 22 slides relative to the base 1 can be parallel to the vehicle width direction. This allows the movable component 22 to move a relatively small distance relative to the base 1, enabling switching between the first and second postures, thus improving the ease of switching.

[0055] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the base 1 has a first guide rail 11, and the movable component 22 has a first slider 2211, with the first guide rail 11 and the first slider 2211 slidably connected. This facilitates a more reliable connection between the base 1 and the movable component 22.

[0056] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments of this application, the vehicle braking system assembly testing device further includes a first power mechanism 8, which includes a first nut and a first lead screw 81. The first nut is fixed to the movable component 22, and the first lead screw 81 is rotatably connected to the base 1. The first lead screw 81 is helically connected to the first nut, and the axial direction of the first lead screw 81 is the same as the extension direction of the first guide rail 11. In this way, the movable component 22 is connected to the base 1 through the first lead screw 81 and the first nut, which makes the load-bearing capacity of the movable component 22 strong. When the driving component 21 triggers the braking process, the movable component 22 can provide stable support for the driving component 21.

[0057] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first power mechanism 8 further includes a first handle 85, which is rotatably connected to the base 1 and drively connected to the first lead screw 81, for driving the first lead screw 81 to rotate relative to the base 1. Of course, in some embodiments of this application, the rotation of the first lead screw 81 relative to the base 1 can also be driven by an electric motor.

[0058] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first power mechanism 8 further includes a first gear 82, a second gear 83, and a drive shaft 84. One end of the drive shaft 84 is coaxially fixed to the first handle 85, and the other end is coaxially fixed to the second gear 83. The first gear 82 is coaxially fixed to the first lead screw 81. The first gear 82 meshes with the second gear 83. The axial direction of the first gear 82 is perpendicular to the axial direction of the second gear 83. For example, the axial direction of the second gear 83 can be parallel to the length direction of the vehicle.

[0059] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the movable component 22 includes a first movable module 221 and a second movable module 222. The first movable module 221 is slidably connected to the base 1, and the second movable module 222 is slidably connected to the first movable module 221, with the relative sliding direction perpendicular to the vehicle width direction. The driving component 21 is disposed on the second movable module 222.

[0060] By sliding the first movable module 221 to the base 1, with the relative sliding direction having a component along the vehicle width direction, the drive component 21 can switch between a first posture and a second posture, allowing personnel to easily operate the vehicle braking system assembly 01. Furthermore, different types of vehicle braking system assemblies 01 often have different dimensions, and after installation on the base 1, the relative positions of the input ends of different types of vehicle braking system assemblies 01 to the base 1 are often inconsistent, primarily varying in a direction perpendicular to the vehicle width direction. By sliding the second movable module 222 to the first movable module 221, with the relative sliding direction perpendicular to the vehicle width direction, the drive component 21 can translate relative to the base 1 along at least one direction perpendicular to the vehicle width direction. This allows the drive component 21 to move to the input ends of different vehicle braking system assemblies 01, triggering different types of vehicle braking system assemblies 01, thus enhancing the adaptability of the vehicle braking system assembly testing device.

[0061] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first movable module 221 and the base 1 can be slidably connected via the first guide rail 11 and the first slider 2211. In some embodiments of this application, the first nut can be disposed on the first movable module 221.

[0062] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first active module 221 has a second guide rail 2212, and the second active module 222 has a second slider 22211, with the second guide rail 2212 and the second slider 22211 slidably connected. This facilitates a more reliable connection between the first active module 221 and the second active module 222.

[0063] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the vehicle braking system assembly testing device further includes a second power mechanism, which includes a second nut and a second lead screw 223. The second nut is fixed to the second movable module 222, and the second lead screw 223 is rotatably connected to the first movable module 221. The second lead screw 223 is helically connected to the second nut, and the axial direction of the second lead screw 223 is the same as the extension direction of the second guide rail 2212. In this way, the second movable module 222 is connected to the first movable module 221 via the second lead screw 223 and the first nut, which makes the second movable module 222 have a strong load-bearing capacity. When the driving component 21 triggers the braking process, the second movable module 222 can provide stable support for the driving component 21.

[0064] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the second power mechanism further includes a second handle 224, which is rotatably connected to the first movable module 221 and drively connected to the second lead screw 223, for driving the second lead screw 223 to rotate relative to the first movable module 221. Of course, in some embodiments of this application, the rotation of the first lead screw 81 relative to the base 1 can also be driven by an electric motor. In some embodiments of this application, the second handle 224 can be coaxially fixed with the second lead screw 223.

[0065] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the second active module 222 includes a first active member 2221 and a second active member 2222. The first active member 2221 is slidably connected to the first active module 221, and the second active member 2222 is slidably connected to the first active member 2221. The sliding direction of the second active member 2222 relative to the first active member 2221, the sliding direction of the first active member 2221 relative to the first active module 221, and the vehicle width direction are all perpendicular to each other. The driving component 21 is disposed on the second active member 2222.

[0066] In this way, the drive component 21 can translate relative to the base 1 in three perpendicular directions. The drive component 21 can be adjusted in position relative to the base 1 more flexibly, so that the output end movement of the drive component 21 can better simulate human feet, and also make the vehicle braking system assembly test device adaptable to more types of vehicle braking system assemblies 01.

[0067] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first movable member 2221 and the first movable module 221 can be slidably connected via the second guide rail 2212 and the second slider 22211. In some embodiments of this application, the second nut can be disposed on the first movable member 2221.

[0068] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first movable member 2221 has a third guide rail 22212, and the second movable member 2222 has a third slider 22221, with the third guide rail 22212 and the third slider 22221 slidably connected. This facilitates a more reliable connection between the first movable member 2221 and the second movable member 2222.

[0069] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the vehicle braking system assembly testing device further includes a third power mechanism, which includes a third nut and a third lead screw. The third nut is fixed to the second movable member 2222, and the third lead screw is rotatably connected to the first movable member 2221. The third lead screw and the third nut are helically connected, and the axial direction of the third lead screw is the same as the extension direction of the third guide rail 22212. In this way, the second movable member 2222 is connected to the first movable member 2221 through the third lead screw and the third nut, which makes the second movable member 2222 have a strong load-bearing capacity. When the driving component 21 triggers the braking process, the second movable member 2222 can provide stable support for the driving component 21.

[0070] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the third power mechanism further includes a third handle 225, which is rotatably connected to the first movable member 2221 and is drively connected to the third lead screw, for driving the third lead screw to rotate relative to the first movable module 221. Of course, in some embodiments of this application, the rotation of the first lead screw 81 relative to the base 1 can also be driven by an electric motor.

[0071] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the sliding direction of the first movable member 2221 relative to the first movable module 221 is parallel to the vehicle length direction. Thus, the sliding direction of the second movable member 2222 relative to the first movable member 2221 is parallel to the vehicle height direction. Since the sliding direction of the first movable member 2221 relative to the first movable module 221 is parallel to the vehicle height direction, and the sliding direction of the second movable member 2222 relative to the first movable member 2221 is parallel to the vehicle length direction, the number of components that need to be translated relative to the base 1 along the vehicle height direction is relatively small in this application. It is understandable that, in the case where the first movable component 2221 slides relative to the first movable module 221 in a direction parallel to the vehicle height direction, during the sliding process of the first movable component 2221 relative to the first movable module 221, the first movable component 2221, the second movable component 2222, and the driving component 21 all need to translate relative to the base 1 along the vehicle height direction. However, in the present application, the second movable component 2222 and the driving component 21 can jointly translate relative to the base 1 along the vehicle height direction, and the first movable component 2221 does not need to translate relative to the base 1 along the vehicle height direction. It is understandable that the translation of components relative to the base 1 along the vehicle height direction requires overcoming gravity. In this application, the number of components that need to translate relative to the base 1 along the vehicle height direction is smaller, and the gravity that needs to be overcome during the movement is also smaller, which helps to reduce energy consumption and improve the stability of the movement.

[0072] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the drive component 21 includes a mounting portion and a movable portion. The mounting portion is rotatably connected to the movable component 22. The axis of rotation of the mounting portion relative to the movable component 22 is parallel to the vehicle width direction. The movable portion is slidably connected to the mounting portion. The direction of sliding of the movable portion relative to the mounting portion is perpendicular to the vehicle width direction. The movable portion includes the output end of the drive component 21.

[0073] By making the axis of rotation of the mounting part relative to the movable part 22 parallel to the vehicle width direction, and the direction of sliding of the movable part relative to the mounting part perpendicular to the vehicle width direction, the angle between the direction of sliding of the movable part relative to the mounting part and the horizontal direction changes during the rotation of the mounting part relative to the movable part 22. This allows the drive part 21 to simulate human legs at different tilt angles, which helps to improve the accuracy of the test.

[0074] It should be explained that, in this embodiment, during the sliding process of the movable part relative to the mounting part, the movable part pushes the input end of the vehicle braking system assembly 01 to move relative to the base 1, triggering the braking process. Taking the drive component 21 including an electric cylinder as an example, the movable part includes the piston rod of the electric cylinder, and the mounting part includes the housing of the electric cylinder.

[0075] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the second movable member 2222 is rotatably connected to a fourth handle 226, which is drively connected to the mounting part and used to drive the mounting part to rotate relative to the second movable member 2222. Of course, in some embodiments of this application, the rotation of the mounting part relative to the second movable member 2222 can also be driven by an electric motor.

[0076] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the first movable member 2221 includes a first plate structure and a second plate structure. The thickness direction of the first plate structure is parallel to the vehicle height direction, and the thickness direction of the second plate structure is parallel to the vehicle width direction. The second plate structure is fixed to the first end of the first plate structure along its own thickness direction. The second movable member 2222 is disposed on the side of the second plate structure near the second end of the first plate structure. The first end and the second end of the first plate structure are opposite ends of the first plate structure. The second movable member 2222 is slidably connected to the second plate structure along the vehicle height direction. The driving component 21 is disposed on the side of the second movable member 2222 away from the second plate structure. The first movable module 221 is disposed on the lower side of the first plate structure along the vehicle length direction. The first movable module 221 is slidably connected to the first plate structure.

[0077] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the loading mechanism 2 further includes a movable component 22, which is slidably connected to the base 1, and a driving component 21 is disposed on the movable component 22. The direction in which the movable component 22 slides relative to the base 1 is perpendicular to the vehicle width direction.

[0078] Different types of vehicle braking system assemblies 01 often have different dimensions. After being installed on the base 1, the relative positions of the input ends of different types of vehicle braking system assemblies 01 and the base 1 are often inconsistent, mainly varying in the direction perpendicular to the vehicle width direction. By making the movable part 22 slidably connected to the base 1, and the relative sliding direction is perpendicular to the vehicle width direction, the drive part 21 can be translated relative to the base 1 in at least one direction perpendicular to the vehicle width direction. This allows the drive part 21 to move to the input ends of different vehicle braking system assemblies 01, triggering different types of vehicle braking system assemblies 01, thus making the vehicle braking system assembly testing device highly adaptable.

[0079] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the movable component 22 includes a third movable module and a fourth movable module. The third movable module is slidably connected to the base 1, and the fourth movable module is slidably connected to the third movable module. The sliding direction of the fourth movable module relative to the third movable module, the sliding direction of the third movable module relative to the base 1, and the vehicle width direction are all perpendicular to each other. The driving component 21 is disposed on the fourth movable module.

[0080] By making the direction in which the fourth active module slides relative to the third active module, the direction in which the third active module slides relative to the base 1, and the vehicle width direction perpendicular to each other, the drive component 21 is set on the fourth active module. This allows the drive component 21 to be adjusted more flexibly in the plane perpendicular to the vehicle width direction, enabling the output end of the drive component 21 to better simulate the movement of a human foot. It also allows the vehicle braking system assembly test device to adapt to more types of vehicle braking system assemblies 01.

[0081] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments of this application, the sliding direction of the third active module relative to the base 1 is parallel to the vehicle length direction. Thus, the sliding direction of the fourth active module relative to the third active module is parallel to the vehicle height direction. Compared to the third active module sliding relative to the base 1 in a direction parallel to the vehicle height direction, the fourth active module sliding relative to the third active module in a direction parallel to the vehicle length direction, in this application, the number of components that need to translate relative to the base 1 along the vehicle height direction is smaller. It is understood that with the method where the third active module slides relative to the base 1 in a direction parallel to the vehicle height direction, during the sliding process of the third active module relative to the base 1, the third active module, the fourth active module, and the drive component 21 all need to translate relative to the base 1 along the vehicle height direction. However, in the method of this application, the fourth active module and the drive component 21 can jointly translate relative to the base 1 along the vehicle height direction, and the third active module does not need to translate relative to the base 1 along the vehicle height direction. It is understandable that the components need to overcome gravity to translate relative to the base 1 along the vehicle height direction. In this application, the number of components that need to translate relative to the base 1 along the vehicle height direction is small, and the gravity that needs to be overcome during the movement is also small, which helps to reduce energy consumption and improve the stability of the movement.

[0082] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the vehicle braking system assembly testing device further includes a sensing module 9, with the drive component 21 connected to the sensing module 9 and configured to adjust the output parameters of the output terminal of the drive component 21 according to the detection information of the sensing module 9. The sensing module 9 includes a component configured to detect at least one of the following: the displacement of the output terminal of the drive component 21 relative to the base 1, the force exerted by the output terminal of the drive component 21 on the input terminal of the vehicle braking system assembly 01, and the output hydraulic pressure of the vehicle braking system assembly 01.

[0083] In this way, the sensor module 9 can detect the actual output parameters of at least one of the drive component 21 and the vehicle braking system assembly 01. Based on the detection results of the sensor module 9, the drive component 21 can adjust its own output parameters, forming a control closed loop. This makes the actual output parameters of the drive component 21 and the vehicle braking system assembly 01 closer to the set parameters, which helps improve the accuracy of the test. In addition, the detection results of the sensor module 9 can also be used for fault diagnosis, facilitating the production and maintenance of the vehicle braking system assembly testing device and the vehicle braking system assembly 01.

[0084] Please refer to Figure 1 , Figure 2 and Figure 3In some embodiments of this application, the drive component 21 includes a drive member 211 and a loading member 212. The loading member 212 is detachably connected to the output end of the drive member 211, and the loading member 212 is configured to be detachably connected to the input end of the vehicle braking system assembly 01. The vehicle braking system assembly testing device also includes a sensing module 9, which includes a force sensor 91 disposed between the loading member 212 and the output end of the drive member 211.

[0085] By detachably connecting the loading element 212 between the output end of the drive component 21 and the input end of the vehicle braking system assembly 01, the loading element 212 can be replaced. In this way, for different types of vehicle braking system assemblies 01, the operator can select different loading elements 212, so that the loading element 212 triggers the vehicle braking system assembly 01 under the drive of the output end of the drive component 21. Thus, the vehicle braking system assembly testing device can adapt to the testing of different types of vehicle braking system assemblies 01, and the vehicle braking system assembly testing device has strong adaptability. Furthermore, a force sensor 91 is disposed between the output end of the loading member 212 and the drive member 211. The force sensor 91 can detect the force between the output end of the drive member 211 and the loading member 212. The output end of the drive member 211 triggers the vehicle braking system assembly 01 through the loading member 212. The force between the output end of the drive member 211 and the loading member 212 is basically equal to the force between the loading member 212 and the vehicle braking system assembly 01. In this way, the force sensor 91 can realize real-time monitoring of the force exerted by the output end of the drive member 21 on the input end of the vehicle braking system assembly 01. Moreover, compared to disposing the force sensor 91 between the input end of the vehicle braking system assembly 01 and the loading member 212, in this application, the force sensor 91 is disposed between the loading member 212 and the output end of the drive member 211. The force sensor 91 does not need to be replaced along with the loading member 212. One force sensor 91 can be used for testing different types of vehicle braking system assemblies 01, which helps to reduce testing costs.

[0086] Please refer to Figure 1 , Figure 2 and Figure 3 In this application embodiment, the driving component 211 can be implemented in various forms, such as an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. In some embodiments of this application, the driving component 21 further includes a driving component 211 bracket, the driving component 211 is fixed to the driving component 211 bracket, and the driving component 211 bracket is rotatably connected to the movable component 22.

[0087] Please refer to Figure 1 , Figure 2 and Figure 3In this embodiment of the application, the loading member 212 is a rigid structure, and the output end of the driving member 211 applies a force to the input end of the vehicle braking system assembly 01 through the loading member 212 to trigger the braking process.

[0088] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the sensing module 9 can be connected to the driving component 21 through the controller 7. The controller 7 can control the driving component 21 and adjust the output parameters of the driving component 21 according to the detection results of the sensing module 9.

[0089] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments of this application, the sensing module 9 includes a displacement sensor 92, which is disposed on the drive member 211. The displacement sensor 92 can be used to monitor the displacement and speed of the output end of the drive member 211 relative to the base 1 in real time.

[0090] Please refer to Figure 1 and Figure 4 In some embodiments of this application, the sensing module 9 includes a hydraulic sensor 93, which is disposed in the oil pipe. The hydraulic sensor 93 can be used to monitor the output hydraulic pressure of the vehicle braking system assembly 01 in real time. The output hydraulic pressure refers to the dynamic pressure of the brake fluid flowing within the oil pipe.
