Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a brake assembly testing mechanism. Background Technology

[0002] The electro-hydraulic braking system (EHB) has a displacement sensor installed on the pedal push rod. The displacement sensor obtains the driver's braking intention, and the electronic control unit (ECU) adjusts the hydraulic pressure in real time to achieve precise braking.

[0003] The distance from the flange mounting surface of the electro-hydraulic braking system assembly to the joint where it is mounted on the pedal needs to be matched according to different vehicle models. Therefore, the distance from the flange mounting surface to the joint where it is mounted on the pedal needs to be tested before the electro-hydraulic braking system assembly leaves the factory. In addition, the mounting bolt holes of the flange also need to be tested to ensure that the electro-hydraulic braking system assembly can be installed smoothly and improve installation efficiency.

[0004] In related technologies, the distance from the flange mounting surface to the joint where the pedal is mounted is measured manually with a ruler, which results in large measurement errors and low measurement efficiency. Furthermore, the inspection of each mounting bolt hole on the flange is also carried out by trial installation of the electro-hydraulic braking system assembly, resulting in low overall inspection efficiency of the electro-hydraulic braking system assembly. Utility Model Content

[0005] One aspect of this utility model is to provide a brake assembly testing mechanism to solve the problem of low overall testing efficiency of electro-hydraulic brake system assemblies.

[0006] A brake assembly testing mechanism is provided, comprising:

[0007] Base;

[0008] The flange inspection structure includes a first support part and a first inspection part. The first inspection part is located on top of the first support part and connected to the first support part. The first support part is fixed to the base. The top surface of the first support part is horizontally arranged. The first support part has a first inspection hole corresponding to the bolt hole of the flange of the EHB assembly. The first inspection hole and the bolt hole are arranged in a one-to-one correspondence. The first support part also has a through hole for the connector of the EHB assembly to be connected to the pedal to pass through.

[0009] The connector inspection structure includes a second support and a second inspection part. The second support is mounted on the base, and the second inspection part is slidably connected to the second support. The second inspection part has a second inspection hole that matches the shape of the connector to be inspected. The second inspection hole penetrates the top surface of the second inspection part and is used to inspect whether the length of the connector is qualified.

[0010] Based on the above technical solutions, optionally, the joint detection structure further includes a positioning detection component, which is used to detect whether the second detection unit has moved into position.

[0011] Based on the above technical solutions, optionally, the positioning detection component includes a position detection element, which is used to detect the position of the second detection unit.

[0012] Based on the above technical solutions, optionally, the positioning detection component includes a photoelectric switch and an identification element, the identification element is located on the bottom surface of the second detection part, and the photoelectric switch is disposed at either end of the second support part.

[0013] Based on the above technical solutions, optionally, the identification element and the second detection unit are an integral structure.

[0014] Based on the above technical solutions, optionally, the identification element is a screw, which is fixed to the bottom of the second detection part and is disposed opposite to the detection part of the photoelectric switch.

[0015] Based on the above technical solutions, optionally, the joint detection structure further includes a position correction component, which is installed on the second support and disposed opposite to the second detection part. The position correction component is used to correct the initial position of the joint so that the axial center axis of the joint is collinear with the central axis of the through hole.

[0016] Based on the above technical solutions, optionally, the position correction component includes a support plate and a correction block, the support plate is fixedly connected to the correction block, and the correction block is located on the side of the support plate facing the connector, the end face of the correction block facing the connector is a vertical plane, and the end face of the correction block facing the connector is parallel to the central axis of the through hole.

[0017] Based on the above technical solutions, optionally, the second support part includes a fixing component and a movable block. The fixing component is respectively provided on both sides of the movable block. A pressure strip extends from the movable block toward the fixing component. The fixing component includes a pressure block, which is fixed to the base. The portion of the pressure block facing the movable block is located above the pressure strip, and the pressure block abuts against the pressure strip.

[0018] Based on the above technical solutions, optionally, the fixing component further includes a fixing block, which is fixed to the base. The pressure block has an oblong hole, through which a screw passes to connect the pressure block and the fixing block. The pressure block protrudes from the side of the pressure strip.

[0019] Optionally, based on the above technical solutions, the first detection unit and the first support unit can be detachably connected.

[0020] The brake assembly testing mechanism provided by this utility model has at least the following beneficial effects:

[0021] The flange inspection structure is used to inspect the bolt holes of the flanges in the electro-hydraulic braking system assembly. The first inspection hole corresponds one-to-one with the flange bolt holes; that is, the arrangement of the first inspection holes is the same as the flange bolt holes. When the connector of the electro-hydraulic braking system assembly passes through the through hole, the flange and the first inspection part are aligned. The flange bolts are then passed through the flange bolt holes. If the bolts can pass through the first inspection holes corresponding to the bolt holes simultaneously, the flange bolt holes of the electro-hydraulic braking system assembly meet the requirements and the inspection is passed. If the bolts can only pass through the bolt holes but not the first inspection holes, the flange bolt holes of the electro-hydraulic braking system assembly do not meet the requirements and the inspection is failed. When inspecting the connector, the connector is suspended. Since the shape of the first inspection hole matches the shape of the connector, the second inspection part is directly pushed to slide relative to the second support part. If the connector can pass through the second inspection part, the length from the connector to the flange meets the assembly requirements and the inspection is passed. If the connector cannot pass through the second inspection part, the length from the connector to the flange does not meet the assembly requirements and the inspection is failed.

[0022] The flange inspection structure and joint inspection structure can be set up to inspect EHB flanges and joints simultaneously in one inspection, thereby improving inspection efficiency. Attached Figure Description

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1 to 4 As shown, a brake assembly testing mechanism is provided. The brake assembly testing mechanism includes a base 1, a flange testing structure 2, and a connector testing structure 3. The flange testing structure 2 includes a first support part 21 and a first testing part 22. The first testing part 22 is located on top of the first support part 21 and connected to the first support part 21. The first support part 21 is fixed to the base 1, and its top surface is horizontally arranged. The first support part 21 has a first testing hole 221 corresponding to the bolt holes of the flange of the EHB assembly, and the first testing hole 221 is arranged one-to-one with the bolt holes. The first support part 21 also has a through hole 222 for the connector connecting the EHB assembly and the pedal to pass through. The connector testing structure 3 includes a second support part 31 and a second testing part 32. The second support part 31 is installed on the base 1, and the second testing part 32 is slidably connected to the second support part 31. The second testing part 32 has a second testing hole 321 that matches the shape of the connector to be tested. The second testing hole 321 penetrates the top surface of the second testing part 32 and is used to detect whether the length of the connector is qualified.

[0037] The flange inspection structure 2 is used to inspect the bolt holes of the flange of the electro-hydraulic braking system assembly. The first inspection hole 221 is set one-to-one with the bolt holes of the flange, that is, the arrangement position of the first inspection hole 221 is the same as that of the flange bolt holes. When the connector of the electro-hydraulic braking system assembly passes through the through hole 222, the flange and the first inspection part 22 are in contact, and the bolts of the flange pass through the bolt holes of the flange. If the bolts can pass through the first inspection hole 221 corresponding to the bolt holes at the same time, then the flange bolt holes of the electro-hydraulic braking system assembly meet the requirements and the inspection is qualified. If the bolts can only pass through the bolt holes but not through the first inspection hole 221, then the flange bolt holes of the electro-hydraulic braking system assembly do not meet the requirements and the inspection is unqualified. When inspecting the joint, the joint is suspended in the air. Since the shape of the second inspection hole 321 matches the shape of the joint, that is, the shape of the second inspection hole 321 is the same as the shape of the joint, the second inspection part 32 is directly pushed to slide relative to the second support part 31. If the joint can pass through the second inspection part 32, the length from the joint to the flange meets the assembly requirements and the inspection is qualified. If the joint cannot pass through the second inspection part 32, the length from the joint to the flange does not meet the assembly requirements and the inspection is unqualified.

[0038] The flange inspection structure 2 and the joint inspection structure 3 can be set up to inspect EHB flanges and joints at the same time in one inspection, thereby improving inspection efficiency.

[0039] In some embodiments, the connector detection structure 3 further includes a positioning detection component, which is used to detect whether the second detection unit 32 has moved into position.

[0040] After the second detection unit 32 moves to a position that the positioning detection component can detect, the positioning detection component detects the second detection unit 32 and completes the detection task. The positioning detection component can avoid the problem of missed detection.

[0041] For example, the positioning detection component includes a position detection element, which is used to detect the position of the second detection unit 32.

[0042] The position detection component can be a CCD camera. After the CCD camera captures the current position of the second detection unit 32, it compares it with the position after the detection is completed. If they are the same, it means that the detection is completed. If they are different, it means that the detection was missed. The second detection unit 32 needs to move towards the connector to achieve the detection purpose.

[0043] Of course, in some other embodiments, the position detection element may be a distance detection sensor, which detects the distance between the second detection unit 32 and the sensor, and compares it with a preset distance stored internally to determine whether the detection is in place.

[0044] In some embodiments, the positioning detection component includes a photoelectric switch and an identification element, with the identification element located on the bottom surface of the second detection section 32 and the photoelectric switch disposed at either end of the second support section 31.

[0045] The photoelectric switch is located at either end of the second support portion 31. For example, the photoelectric switch is located at the first end of the second support portion 31, while the second detection portion 32 is located at the second end of the second support portion 31. The first and second ends are positioned opposite to each other. An identification element is provided on the bottom surface of the second detection portion 32. Moving the second detection portion 32 will also cause the identification element to move towards the photoelectric switch. When the identification element approaches the photoelectric switch and reaches the identification position of the photoelectric switch, the photoelectric switch detects the second detection portion 32, indicating that the second detection portion 32 has moved into place, and the detection is complete. When the photoelectric switch and the second detection portion 32 are located at the same end of the second support portion 31, the second detection portion 32 moves the identification element away from the photoelectric switch. When the photoelectric switch can no longer identify the identification element, it indicates that the second detection portion 32 has moved into place, and the detection is complete.

[0046] In some embodiments, the identification element and the second detection unit 32 are integrated into one structure.

[0047] This facilitates the assembly of the brake assembly testing mechanism, reduces assembly steps, and makes it readily available.

[0048] In some embodiments, the identification element is a screw, which is fixed to the bottom of the second detection part 32 and disposed opposite to the detection part of the photoelectric switch.

[0049] The screw is assembled in the second detection part 32 and can be adjusted up and down according to the position of the photoelectric switch, thereby improving the detection accuracy of the photoelectric switch. In addition, the screw is low in cost, thereby reducing the overall manufacturing cost of the brake assembly detection mechanism.

[0050] like Figure 5 As shown, in some embodiments, the second detection unit 32 has a slide groove 322, which is a T-shaped slide groove. The top of the moving block 311 has a T-shaped structure, and the moving block 311 passes into the T-shaped slide groove 322 to realize the sliding connection between the second detection unit 32 and the moving block 311.

[0051] In some embodiments, the connector detection structure 3 further includes a position correction component 33, which is installed on the second support 31 and disposed opposite to the second detection part 32. The position correction component 33 is used to correct the initial position of the connector so that the axial center axis of the connector is collinear with the central axis of the through hole 222.

[0052] When the central axis of the connector is set at an angle to the central axis of the through hole 222, there is a problem with the placement of the connector. For example, the connector may enter the support but the length does not meet the requirements. In this case, the position of the connector needs to be corrected. The position correction component 33 can make the connector be located in the position to be tested and will not be offset, thereby improving the testing efficiency and the testing accuracy.

[0053] The position correction assembly 33 includes a support plate 331 and a correction block 332. The support plate 331 is fixedly connected to the correction block 332 and the support plate 331 is fixedly connected to the moving block 311. The correction block 332 is located on the side of the support plate 331 facing the connector. The end face of the correction block 332 facing the connector is a vertical plane. The end face of the correction block 332 facing the connector is parallel to the central axis of the through hole 222. This allows the connector to be pushed to correct its position.

[0054] like Figure 7 As shown, the support plate 331 has a mounting groove 3311 at its bottom. The movable block 311 is inserted into the mounting groove 3311, and the support plate 331 is fixedly connected to the movable block 311 by screws. The support plate 331 has a mounting hole 3312, and the correction block 332 is inserted into the mounting hole 3312.

[0055] Combination Figure 3 , Figure 4 and Figure 6As shown, in some embodiments, the second support 31 includes a fixing component and a moving block 311. Fixing components are respectively provided on both sides of the moving block 311. A pressure strip 3111 extends from the moving block 311 toward the fixing component. The fixing component includes a pressure block 312. The pressure block 312 is fixed to the base 1. The portion of the pressure block 312 facing the moving block 311 is located above the pressure strip 3111. The pressure block 312 abuts against the pressure strip 3111.

[0056] For example, the pressure block 312 has a groove, and the pressure strip 3111 can extend into the pressure block 312 and be pressed down against the side wall of the pressure block 312, thereby realizing the adjustment of the position of the moving block 311.

[0057] In some other embodiments, the second support 31 is an integrally formed structure, which can improve the overall assembly efficiency of the brake assembly testing mechanism.

[0058] In some embodiments, the fixing component further includes a fixing block 313, which is fixed to the base 1. The pressure block 312 has a waist-shaped hole 3121, and a screw passes through the waist-shaped hole 3121 to connect the pressure block 312 and the fixing block 313. The side of the pressure block 312 facing the pressure strip 3111 protrudes from the pressure block 312.

[0059] The pressure block 312 has a waist-shaped hole 3121, so the position of the moving block 311 can be adjusted as needed before the screw is tightened, thereby ensuring that the second detection part 32 will not be offset relative to the connector and avoiding large errors in detection.

[0060] In some embodiments, the first detection unit 22 and the first support unit 21 are detachably connected. The first support unit 21 can be replaced according to different EHB models to adapt to the detection of different EHB models. For example, the first detection unit 22 and the first support unit 21 are fixedly connected by screws, and when the first support unit 21 needs to be replaced, the screws can be unscrewed directly to achieve replacement.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
