Description

Technical Field

[0001] The present invention relates to the field of production and manufacturing of EMB calipers, and more specifically, to an on-line performance detection device for EMB calipers. Background Art

[0002] An EMB (Electronic Mechanical Brake) caliper, that is, an electronic mechanical brake caliper, is an advanced technology in modern vehicle braking systems; it uses electrical signals to control a drive motor installed on the brake caliper to generate a braking clamping force, realizing the full electronic control of the braking system. Compared with traditional hydraulic braking systems, EMB calipers have advantages such as simple structure, fast response, and precise control, and can better support the requirements of high-order intelligent driving for chassis control.

[0003] The internal structure of an EMB caliper is complex and includes multiple key components. Among them, the performance of the motor gear unit (MGU), the caliper air chamber, and the piston is particularly crucial. As the power source of the braking force, the operating state of the MGU directly determines the movement speed and stability of the piston, thereby affecting the braking response time and braking force. At the same time, the sealing performance of the caliper air chamber and the working state of the piston are also directly related to the braking efficiency and long-term reliability of the EMB caliper.

[0004] However, current detection methods for EMB calipers mostly rely on manual operation and judgment, with relatively low automation. This not only increases the labor intensity of operators but also is easily affected by human factors, making it difficult to ensure the stability and consistency of detection results. In addition, since the performance detection of EMB calipers covers multiple detection items, this requires frequent switching to different detection stations during the detection process.

Beneficial Effects

[0017] In the present invention, the floating detection mechanism cooperates with the EOL detection matching component, the torque detection matching component and the airtight detection matching component to comprehensively detect the various performances of the EMB caliper. This multifunctional integrated design avoids the switching of the caliper between different detection platforms during the detection process, reduces the time and cost of replacing different detection equipment, and greatly improves the detection efficiency; it also avoids the error introduced by the switching of the caliper between detection platforms, and improves the accuracy of the detection.

[0018] If the test device is fixed on a certain structure during the detection process, then when the force is transmitted to the test device, part of the force will also be transmitted to the structure, which will cause the test data measured by the test device to be easily biased. Therefore, in the present invention, the design of the movable gap between the assembly block and the assembly space allows the test device to have a certain degree of adaptive adjustment during the detection process, and tries to avoid the force applied to the test device by the EMB caliper from being transmitted to other structures, thereby ensuring the accuracy of force transmission and feedback during the detection process, and further improving the accuracy and reliability of the detection.

[0019] In the present invention, through the coordination and action of the assembly plate, the movable plate, the force sensor and the compression spring, the change of the interaction force between the movable plate and the EMB caliper piston can be captured in real time and accurately during the detection process; the test device can simulate the actual working state of the EMB caliper during the detection process, realize dynamic detection, and thus improve the accuracy of the detection.

[0020] In the present invention, by setting the adjustment block, when the test device cooperates with the EMB caliper, the test device will raise the heights of the assembly plate, the movable plate and the force sensor according to the thickness of the adjustment block; and then the assembly block is raised synchronously, so that the assembly block can be in the middle of the assembly space during the detection process, and try to avoid the upper and lower ends of the assembly block abutting against the upper and lower ends of the assembly space during the test, causing part of the force to be transmitted to the installation part of the device and affecting the detection result.

[0021] In the present invention, due to the width difference between the first part and the third part and the second part, the assembly block of the test device can be stably located at the lowest point of the assembly space when the test work is not being performed, so that other areas of the EMB caliper can abut against the adjustment block of the test device when the test work starts, thereby stably lifting the assembly plate, the movable plate and the force sensor for stable data detection.

[0022] In the present invention, the width at the second area corresponds to the width at the second part, the length at the second area is longer than the length at the second part, and the length direction of the assembly block and the length direction of the assembly space correspond to the length direction of the guide shaft; when the testing device is subjected to the force from the piston, the assembly block can only move in the direction corresponding to the movement of the EMB caliper piston, preventing it from moving in other directions, resulting in inaccurate test results.

[0023] In the present invention, the adjustment block is in the shape of an inverted frustum, and through the setting of its contact surface, when the testing device enters the corresponding area of ​​the caliper under the drive of the driving device, the adjustment block is driven to increase its height due to the contact between the inclined surface and other areas of the caliper and the continuous force provided by the driving device, thereby achieving that the assembly block can be in the middle of the assembly space during the detection process.

[0024] In the present invention, by setting the first driving cylinder and the second driving cylinder, the testing device can achieve horizontal and vertical movements, so that the testing device can flexibly adjust the position and angle to meet different testing requirements.

[0025] In the present invention, the motor shaft and transmission rod of the torque output motor are connected to the measuring shafts at the upper and lower ends of the torque sensor through a coupling, forming an accurate torque transmission and measurement system; at the same time, since the motor shaft and transmission rod of the torque output motor are respectively connected to the measuring shafts at the upper and lower ends of the torque sensor, the torque sensor can not only detect the torque output by the torque output motor, but also detect the torque of the piston inside the EMB caliper, providing high-precision torque measurement capability.

[0026] In the present invention, the detection power supply device realizes the flexible adjustment of the power supply interface in the horizontal and vertical directions through the power supply adjustment unit; this adjustment ability enables the power supply interface to accurately dock with MGU of different models or positions, improving the adaptability and versatility of the equipment; after the detection power supply device supplies power to the MGU, the MGU starts to work to drive the piston of the EMB caliper, thereby realizing the EOL detection.

[0027] In the present invention, the second connection plate is fixed to the first connection plate using positioning bolts. This design not only ensures the stability of the power supply interface during the adjustment process but also allows for fine-tuning within a certain range to achieve more precise positioning; the adjustment notch is designed in an arc shape, which means that the second connection plate can be rotated and adjusted relative to the first connection plate within a certain angle range, further enhancing the flexibility of the power supply interface.

[0028] In the present invention, the conveying track provided on the tabletop enables the tooling carrying the EMB caliper to automatically move in front of the test equipment without manual handling or position adjustment; this automated conveying process significantly improves the test efficiency and reduces manual intervention and waiting time.

[0029] In the present invention, through the design of the lifting device and the design of the notch on the tooling, when the lifting mating plate abuts against the bottom of the tooling, the air pipe joint can smoothly expose from the notch; it is convenient for people to block and inflate the air passage in the EMB caliper body that communicates with the air chamber through the cooperation of the air pipe joint and the air inlet pipe. When the air pressure reaches a certain level, the piston is pushed out, thereby detecting the sealing effect of the caliper air chamber; through the design of the lifting device, it is also possible to prevent interference and damage between the air pipe joint and the tooling when the tooling conveys the EMB caliper.

[0048] As Figure 1-14 As shown in the figure, an on-line performance detection device for an EMB caliper includes a detection module 1 and a tooling 2 for fixing the caliper. The detection module 1 is arranged above the tooling 2; the detection module 1 includes a floating detection mechanism 3, an EOL detection cooperation component 4, a torque detection cooperation component 5, and an airtight detection cooperation component 6; through the cooperation of the floating detection mechanism 3 with the EOL detection cooperation component 4, the torque detection cooperation component 5, and the airtight detection cooperation component 6, various performances of the EMB caliper 9 can be comprehensively detected. This multi-functional integrated design avoids the conversion of the caliper between different detection stations during the detection process, reduces the time and cost of replacing different detection devices, and greatly improves the detection efficiency; at the same time, it also avoids the introduction of errors caused by the conversion of the caliper between detection stations, and improves the accuracy of the detection.

[0049] In the present invention, the floating detection mechanism 3 includes a test device 30 and a device installation part 31. An assembly block 32 and an assembly space 33 are respectively arranged on the test device 30 and the device installation part 31; the assembly block 32 is assembled in the assembly space 33, and there is an activity gap between the assembly block 32 and the inner wall of the assembly space 33; during performance detection, both ends of the test device 30 respectively abut against the piston of the caliper and other areas of the caliper. If the test device 30 is fixed to a certain structure during the detection process, then when a force is transmitted to the test device 30, part of the force will also be transmitted to this structure, which will lead to certain deviations in the detection data measured by the test device 30; therefore, in the present invention, through the design of the activity gap between the assembly block 32 and the assembly space 33, the test device 30 is allowed to have a certain degree of adaptive adjustment during the detection process, so that the test device 30 is accurately abutted against the piston and other areas of the EMB caliper 9, and tries to avoid the force exerted by the EMB caliper 9 on the test device 30 from being transmitted to other structures, ensuring the accuracy of the force transmission and feedback during the detection process; further improving the detection accuracy and reliability.

[0050] In this embodiment, the assembly block 32 moves vertically within the assembly space 33, and the movement gap is in the vertical direction of the assembly block 32; the assembly block 32 is arranged on the testing device 30, and an adjusting block 351 is arranged at the bottom of the testing device; the thickness of the adjusting block 351 is less than the length of the movement gap; thus, the device can lift the assembly block 32 by the presence of the adjusting block 351 to make it in the middle of the assembly space 33, so as to avoid the force applied by the caliper 9 to the testing device 30 being transmitted to other structures as much as possible, ensuring the accuracy of force transmission and feedback during the detection process.

[0051] In the present invention, the EOL detection cooperation assembly 4 includes a detection power supply device 41 with adjustable position. During EOL detection, an MGU is assembled on the caliper, and the detection power supply device 41 cooperates with the MGU to supply power, thereby facilitating EOL detection. The torque detection cooperation assembly 5 includes a torque detection device 51 and a detection adjustment device 52. During torque detection, no MGU is assembled on the caliper, and the detection adjustment device 52 drives the torque detection device 51 into the caliper interior and cooperates with the caliper piston to achieve precise detection of the caliper torque. The airtightness detection cooperation assembly 6 includes an air inlet device 61. During airtightness detection, the air inlet device 61 seals the special interface for testing the airtightness of the caliper and introduces gas into the caliper, achieving reliable detection of the airtightness performance of the caliper.

[0052] It should be noted that the sealing performance of the caliper body air chamber of the EMB caliper 9 is related to the braking performance and long-term reliability of the EMB caliper 9. Therefore, to ensure that the sealing performance of the caliper body air chamber meets the production requirements, a special interface for sealing performance testing and a gas passage leading to the caliper body air chamber are provided on the caliper body of the EMB caliper 9, so that the air inlet device 61 can introduce gas into the caliper body air chamber to detect the airtightness performance of the caliper.

[0053] In the present invention, the test device 30 includes an assembly plate 34, a movable plate 35, and a force sensor 36; the assembly block 32 is disposed on the assembly plate 34, and a guide shaft 37 is further assembled on the assembly plate 34; an activity through hole is provided on the assembly plate 34, and the assembly plate 34 is movably engaged with the guide shaft 37 through the activity through hole; the movable plate 35 is located between the assembly plate 34 and the tooling 2, and one end of the guide shaft 37 is fixedly connected to the movable plate 35; the length direction of the guide shaft 37 and the activity direction of the caliper piston are the same as the activity direction of the assembly block 32 in the assembly space 33, facilitating the force sensor 36 to detect the acting force of the caliper piston and obtaining a test result based on the measured acting force of the caliper piston; a compression spring 38 is sleeved on the guide shaft 37, and both ends of the compression spring 38 are respectively engaged with the assembly plate 34 and the movable plate 35; the force sensor 36 is fixed on the assembly plate 34 and is located between the assembly plate 34 and the movable plate 35; during performance testing, the relative surfaces of the movable plate 35 and the assembly plate 34 respectively abut against the piston of the caliper and other areas of the caliper. Through the cooperation of the movable plate 35 and the guide shaft 37, and the action of the compression spring 38, the change in the mutual acting force between the movable plate 35 and the piston of the EMB caliper 9 can be captured in real time and accurately during the detection process; the test device 30 can simulate the actual working state of the EMB caliper 9 during the detection process, realizing dynamic detection. This dynamic detection method is closer to the actual use situation and can more comprehensively evaluate the performance of the EMB caliper 9, including its response speed, stability, and long-term reliability, thereby improving the accuracy of the detection.

[0054] In the present invention, the assembly block 32 moves vertically in the assembly space 33, and the movement direction of the assembly block 32 corresponds to the length direction of the guide shaft 37; the assembly block 32 includes a first part 321, a second part 322, and a third part 323, which are arranged in sequence from top to bottom, and the widths at the first part 321 and the third part 323 are both smaller than the width at the second part 322; the assembly space 33 includes a first area 331, a second area 332, and a third area 333, which are arranged in sequence from top to bottom, and the shape of the first area 331 matches the shape of the first part 321, and the shape of the third area 333 matches the shape of the third part 323; the width at the second area 332 corresponds to the width at the second part 322, and the length at the second area 332 is longer than the length at the second part 322; the length direction of the assembly block 32, the length direction of the assembly space 33, and the length direction of the guide shaft 37 correspond to each other; when the test device 30 is subjected to the acting force from the piston, the assembly block 32 can only move in the direction corresponding to the movement of the piston of the EMB caliper 9, preventing its movement in other directions from causing inaccurate test results.

[0055] In this embodiment, the movable plate 35 is located below the assembly plate 34, and the bottom end of the guide shaft 37 is fixedly connected to the upper surface of the movable plate 35; an adjustment block 351 is fixedly arranged on the lower surface of the movable plate 35, and the adjustment block 351 is in the shape of an inverted truncated cone, and its lower bottom surface with a larger area is connected to the lower surface of the movable plate 35, and its side surface is a contact surface 352; the thickness of the adjustment block 351 is less than the length at the second area 332; by setting the adjustment block 351, the test device 30 reaches the EMB caliper 9 and needs to be inspected. When the position to be measured is reached and the piston of the EMB caliper 9 is not working and before the EMB caliper 9 is braked, the testing device 30 will raise the heights of the assembly plate 34, the movable plate 35 and the force sensor 36 according to the thickness of the adjusting block 351; and then the assembly block 32 will be raised synchronously, so that the assembly block 32 can be in the middle of the assembly space 33 during the testing process, and try to avoid the upper and lower ends of the assembly block 32 abutting against the upper and lower ends of the assembly space 33 during the test, causing part of the force to be transmitted to the device mounting portion 31 and affecting the test result.

[0056] In this embodiment, the length difference between the second area 332 and the second portion 322 is the length of the movable gap of the assembly block 32 in the assembly space 33 .

[0057] In the present invention, through the width difference between the first part 321 and the third part 323 and the second part 322, the assembly block 32 of the test device 30 can be stably located at the lowest point of the assembly space 33 when the test work is not being performed, so that other areas of the EMB caliper 9 can abut against the adjustment block 351 of the test device 30 when the test work starts, thereby stably lifting the assembly plate 34, the movable plate 35 and the force sensor 36 for stable data detection.

[0058] In the present invention, the second part has the largest width, and this design helps to enhance the overall structural stability of the assembly block; the wide second part can provide a larger supporting area to resist the impact and deformation of external forces, thereby improving the durability and reliability of the assembly block.

[0059] In the present invention, the assembly blocks 32 are symmetrically arranged at the left and right ends of the assembly plate 34; the device mounting portion 31 includes a device mounting plate 311 and a device mounting rod 312 symmetrically arranged on the device mounting plate 311, and the assembly space 33 is symmetrically arranged on the device mounting rod 312 symmetrically; the floating detection mechanism 3 also includes a driving device 39 for driving the device mounting portion 31 and the test device 30 to move, and the driving device 39 drives the test device 30 to reach the detection position and cooperate with the caliper to carry out subsequent detection procedures; the assembly blocks 32 are symmetrically arranged at the left and right ends of the assembly plate 34. This layout helps to balance the weight distribution of the entire detection equipment, reduce the tilt or shaking that may occur during the assembly or detection process, thereby improving the stability of assembly and detection.

[0060] In the present invention, the adjusting block 351 is in the shape of an inverted frustum of a cone. Through the setting of its contact surface 352, when the testing device 30 enters the corresponding area of the caliper driven by the driving device 39, driven by the contact between the inclined surface and other areas of the caliper and the continuous force provided by the driving device 39, the adjusting block 351 moves to increase its own height, so as to enable the assembly block 32 to be located in the middle of the assembly space 33 during the detection process.

[0080] After the preparation stage is completed, the steps of EOL detection are as follows:

[0081] (1) The operator adjusts the positional relationship between the first connecting plate 434 and the second connecting plate 435 by adjusting the cooperation of the notch 436, the positioning bolt, and the positioning hole according to the model of the EMB caliper 9 and the model of the MGU on the EMB caliper 9, thereby changing the position orientation of the power supply interface 42.

[0082] (2) Control the vertical adjustment cylinder 431 and the horizontal adjustment cylinder 432 to work to make the power supply interface 42 cooperate with the MGU to complete the power supply to the MGU.

[0085] After the preparation stage is completed, the steps for torque detection are as follows:

[0086] (1) Control the detection and adjustment cylinder 522 to work to drive the torque detection device 51 to adjust its position, so that the transmission part 515 enters the inside of the caliper and cooperates with the piston of the caliper.

[0087] (2) The torque output motor 511 works to apply a rotational force to the piston of the caliper, and then torque detection is carried out.

[0088] (3) After the detection is completed, control the detection and adjustment cylinder 522 to work to reset the torque detection device 51 and release the cooperation between the transmission part 515 and the caliper piston.

[0089] After the preparation stage is completed, the steps for airtightness detection are as follows:

[0090] (1) Manually or using a robotic arm, connect one end of the air inlet pipe to the air pipe joint 62, and then block the dedicated airtightness test interface of the caliper with the other end of the air inlet pipe.

[0091] (2) The air supply device outside or inside the equipment supplies air to the air pipe joint 62 to introduce gas into the caliper; thus, the airtightness detection is completed.

[0092] (3) Remove the air inlet pipe and release the blockage of the dedicated airtightness test interface of the caliper by the air inlet pipe.

[0093] After the EOL detection, torque detection, and airtightness detection are completed, the steps are as follows:
