Description

Technical Field

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

[0002] EMB (Electronic Mechanical Brake) calipers are an advanced technology in modern automotive braking systems. They use electrical signals to control the drive motor installed on the caliper to generate brake clamping force, thus achieving full electronic control of the braking system. Compared with traditional hydraulic brake systems, EMB calipers have the advantages of simple structure, fast response, and precise control, and can better support the needs of high-level intelligent driving for chassis control.

[0003] The internal structure of the EMB caliper is complex and contains multiple key components, among which the performance of the motor gear unit (MGU), caliper air chamber and piston is particularly critical. As the power source of the braking force, the operating state of the MGU directly determines the movement speed and stability of the piston, which in turn affects 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 performance and long-term reliability of the EMB caliper.

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

Beneficial Effects

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] In the present invention, the detection power supply device realizes flexible adjustment of the power supply interface in the horizontal and vertical directions through the power supply adjustment part; this adjustment capability enables the power supply interface to accurately dock with MGUs of different models or positions, thereby improving the adaptability and versatility of the equipment; when the detection power supply device supplies power to the MGU, the MGU starts to work to drive the piston of the EMB caliper to work, thereby realizing EOL detection.

[0026] In the present invention, the second connection plate is fixed to the first connection plate by using positioning bolts. This design not only ensures the stability of the power supply interface during the adjustment process, but also allows fine adjustment 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 within a certain angle range relative to the first connection plate, further enhancing the flexibility of the power supply interface.

[0027] In the present invention, the conveying track arranged on the table panel enables the tooling carrying the EMB caliper to automatically move in front of the testing equipment without manual handling or position adjustment; this automated conveying process significantly improves the testing efficiency and reduces manual intervention and waiting time.

[0028] In the present invention, through the design of the lifting device and the design of the notch on the tooling, the air pipe joint can be smoothly exposed from the notch when the lifting matching plate abuts against the bottom of the tooling; it is convenient for people to seal and inflate the air path connected to the air chamber in the caliper body of the EMB caliper through the cooperation of the air pipe joint and the air inlet pipe, and when the air pressure reaches a certain level, the piston is pushed out to detect the sealing effect of the air chamber of the caliper body; the design of the lifting device can also avoid interference between the air pipe joint and the tooling when the tooling is transporting the EMB caliper, causing damage.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0047] like Figure 1-14 As shown, an EMB caliper online performance detection device includes a detection module 1 and a fixture 2 for fixing the caliper, and the detection module 1 is arranged above the fixture 2; the detection module 1 includes a floating detection mechanism 3, an EOL detection matching component 4, a torque detection matching component 5 and an airtight detection matching component 6; through the floating detection mechanism 3, the EOL detection matching component 4, the torque detection matching component 5 and the airtight detection matching component 6, the various performances of the EMB caliper 9 can be comprehensively detected. 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.

[0048] In the present invention, the floating detection mechanism 3 includes a test device 30 and a device mounting portion 31, and the test device 30 and the device mounting portion 31 are respectively provided with an assembly block 32 and an assembly space 33; the assembly block 32 is assembled in the assembly space 33, and there is a movable gap between the assembly block 32 and the inner wall of the assembly space 33; during performance testing, the two 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 on a certain structure during the detection process, then when the force is transmitted to the test device 30, part of the force will also be transmitted to the structure, which will cause the detection data measured by the test device 30 to be easily biased. Therefore, in the present invention, the movable gap design between the assembly block 32 and the assembly space 33 allows the test device 30 to have a certain degree of adaptive adjustment during the detection process, so that the test device 30 can accurately abut against the piston and other areas of the EMB caliper 9, and the force applied to the test device 30 by the EMB caliper 9 can be avoided as much as possible 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.

[0049] In this embodiment, the assembly block 32 moves vertically in the assembly space 33, and the movable gap is in the vertical direction of the assembly block 32; the assembly block 32 is arranged on the test device 30, and an adjustment block 351 is arranged at the bottom of the test device; the thickness of the adjustment block 351 is less than the length of the movable gap; thereby, the device can raise the assembly block 32 through the existence of the adjustment block 351, so that it is located in the middle of the assembly space 33, and try to avoid the force applied to the test device 30 by the caliper 9 to be transmitted to other structures, thereby ensuring the accuracy of force transmission and feedback during the detection process.

[0050] In the present invention, the EOL detection matching component 4 includes a detection power supply device 41 with adjustable position. During EOL detection, the caliper is equipped with an MGU. The detection power supply device 41 cooperates with the MGU and supplies power, thereby conveniently performing EOL detection. The torque detection matching component 5 includes a torque detection device 51 and a detection adjustment device 52. During torque detection, the caliper is not equipped with an MGU. The detection adjustment device 52 drives the torque detection device 51 into the interior of the caliper and cooperates with the caliper piston to achieve accurate detection of the caliper torque. The airtight detection matching component 6 includes an air intake device 61. During airtight detection, the air intake device 61 blocks the special interface for the sealing test of the caliper and introduces gas into the caliper, thereby achieving reliable detection of the airtight performance of the caliper.

[0051] It should be noted that the sealing performance of the caliper body air chamber of the EMB caliper 9 is related to the braking efficiency and long-term reliability of the EMB caliper 9. Therefore, in order to ensure that the sealing performance of the caliper body air chamber meets the production requirements, a special sealing test interface and a gas channel leading to the caliper body air chamber are provided on the caliper body of the EMB caliper 9, so that the air intake device 61 can pass the gas into the caliper body air chamber to realize the detection of the airtight performance of the caliper.

[0052] 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 arranged on the assembly plate 34, and the assembly plate 34 is also equipped with a guide shaft 37; an active through hole is arranged on the assembly plate 34, and the assembly plate 34 can be movably matched with the guide shaft 37 through the active 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 movable direction of the caliper piston are consistent with the assembly block 32 in the assembly The movement direction in the space 33 is consistent, which is convenient for the force sensor 36 to detect the force of the caliper piston and obtain the detection result according to the measured force of the caliper piston; the guide shaft 37 is provided with a compression spring 38, and the two ends of the compression spring 38 are respectively matched 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 the performance test, the relative surfaces of the movable plate 35 and the assembly plate 34 are respectively in contact with 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 of the interaction force between the movable plate 35 and the piston of the EMB caliper 9 can be captured in real time and accurately during the test process; the test device 30 can simulate the actual working state of the EMB caliper 9 during the test process to achieve 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 test.

[0053] In the present invention, the assembly block 32 moves vertically in the assembly space 33, and the moving direction of the assembly block 32 corresponds to the length direction of the guide shaft 37; the assembly block 32 includes a first portion 321, a second portion 322 and a third portion 323, which are sequentially arranged from top to bottom, and the width of the first portion 321 and the width of the third portion 323 are both smaller than the width of the second portion 322; the assembly space 33 includes a first area 331, a second area 332 and a third area 333, which are sequentially arranged from top to bottom, and the shape of the first area 331 is similar to that of the first portion 32 1, the shape of the third area 333 matches the shape of the third part 323; the width of the second area 332 corresponds to the width of the second part 322, and the length of the second area 332 is longer than the length of the second part 322; the length direction of the assembly block 32 and the length direction of the assembly space 33 correspond to the length direction of the guide shaft 37; so that when the test device 30 is subjected to the 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, so as to prevent it from moving in other directions and causing inaccurate test results.

[0054] 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.

[0055] 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 .

[0056] 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.

[0057] 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.

[0058] 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.
