Description

Technical Field

[0001] The invention relates to a performance detection technology for an automobile EPB brake caliper. Background Art

[0002] When testing the electronic parking efficiency of automotive EPB calipers, the output force and output current of the product need to be detected through pressure sensors and electronic power head connectors, respectively. Currently, when testing the electronic parking efficiency of EPB calipers, the pressure sensor is usually manually placed between the product's piston and the caliper body's opening, and the power head connector is manually installed into the electronic power head's socket. Testing in this manner affects the output force test results, as the pressure sensor cannot be fixed in position during manual placement, resulting in inaccurate product test results. Manual installation of the electronic power head connector is extremely difficult during disassembly and installation, placing high labor intensity on the operator and easily damaging the electronic power head connector. Furthermore, this testing method cannot achieve production automation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automobile EPB caliper electronic parking efficiency detection structure, which can automatically install the power head connector to the electronic power head socket, and automatically detect the output force to ensure accurate output force detection results.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: an automobile EPB caliper electronic parking efficiency detection structure, comprising:

[0005] The product mounting seat is used to mount the EPB product, and the product mounting seat is driven to rise and fall by the first linear drive; the connector mounting seat is located above the product mounting seat, and the connector mounting seat includes a mounting base, a second linear drive vertically mounted above the mounting base, a connector connecting plate with the connector mounted thereon, and an intermediate transmission assembly connected to the connector connecting plate. The second linear drive drives the intermediate transmission assembly, and the intermediate transmission assembly converts the up and down movement of the second linear drive into a horizontal extension and retraction movement of the connector connecting plate, so that when the connector is extended, the connector is inserted into the connector socket of the EPB product power head so that the PIN pins therein contact, and when the connector is retracted, the connector is pulled out of the connector socket of the EPB product power head;

[0006] The product output force detection mechanism includes a pressure plate located above the EPB product caliper hook and a pressure sensor connected to the pressure plate for detecting the output force of the EPB product. The pressure plate is driven by the third linear drive to extend and retract horizontally forward and backward, and is driven by the fourth linear drive to rise and fall.

[0007] Optionally, the pressure plate includes a first horizontal portion and a first vertical portion, the upper surface of the first horizontal portion is provided with a pressure sensor mounting groove for mounting a pressure sensor, and a pressure sensor pad in contact with the pressure sensor is provided above the first horizontal portion.

[0008] Optionally, the pressure plate is connected to a sensor pad connecting plate, and the sensor pad connecting plate includes a second horizontal portion and a second vertical portion connected in an L-shape, and the first vertical portion is fixed to the second vertical portion.

[0009] Optionally, the third linear drive is a third cylinder, the cylinder push rod of the third cylinder is connected to a sliding plate, the sliding plate is connected to a first guide rail slider, and the first guide rail slider is slidably matched with the first linear guide rail.

[0010] Optionally, the fourth linear actuator is a fourth cylinder, the fourth cylinder is mounted on the sliding plate, and the cylinder push rod of the fourth cylinder is connected to the second horizontal portion.

[0011] Optionally, a support frame is installed on the sliding plate, and the support frame is provided with a horizontal extension portion, and the horizontal extension portion is threadedly connected to a height-limiting bolt that cooperates with the second horizontal portion to limit the rising height of the sensor pad connection plate.

[0012] Optionally, a support frame is installed on the sliding plate, the second vertical portion is connected to a second guide rail slider, the support frame is provided with a second linear guide rail, and the second guide rail slider is slidably engaged with the second linear guide rail.

[0013] Optionally, the second linear actuator is a second cylinder vertically installed above the mounting base.

[0014] Optionally, the intermediate transmission assembly includes a connecting rod, a slide, and a guide rod. The connecting rod consists of an upper section and a lower section. There is a fixed angle between the upper section and the lower section, and the connection position between the upper section and the lower section is hinged to a fixed fulcrum. The first end of the connecting rod is hinged to the cylinder top rod of the second cylinder. The slide is provided with a slide groove. The second end of the connecting rod is provided with a rolling bearing. The rolling bearing is slidably connected to the slide groove, and the guide rod is connected to the connector connecting plate.

[0015] Optionally, the slide plate is connected to a return spring.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. The manual installation method of pressure sensors and electronic power head connectors has been improved. The EPB product to be tested is installed on the product mounting seat. The second linear drive on the connector mounting seat inserts the connector into the connector port of the EPB product power head through the intermediate transmission component to make the PIN pins in the two contact. The pressure plate installed with the pressure sensor in the product output force detection mechanism is driven by the third linear drive to extend and retract back and forth, and driven up and down by the fourth linear drive, so that the pressure plate is located above the caliper hook of the EPB product. When the connector is inserted into the connector port of the EPB product power head, the active parts of the EPB product move down and act on the pressure sensor to perform product output force detection. During the whole process, the operator only needs to trigger the switch, and the rest of the detection actions are performed automatically, thereby improving the accuracy of product detection and reducing the labor intensity of operators.

[0018] 2. The pressure sensor is pre-installed in the pressure sensor installation slot, and its position is fixed. The pressure sensor and the pressure sensor pad work together to detect the output force of the product, and the output force detection result is more accurate.

[0019] 3. Set a limited height bolt to limit the rising height of the sensor pad connecting plate, thereby ensuring that the pressure sensor can interact with the pressure sensor pad.

[0020] 4. The first linear guide rail ensures that the horizontal movement position of the pressure plate is accurate, and the second linear guide rail ensures that the upper and lower positions of the pressure plate are accurate, thereby ensuring that the product output force test results are accurate.

[0021] 5. Through the linkage of the intermediate transmission assembly, the direction of the second linear drive force is changed, so that the connector can be accurately inserted into the socket of the EPB product power head. In addition, the intermediate transmission assembly can prevent the driver from directly driving the connector to insert into the socket of the EPB product power head to generate a large impact force.

[0022] 6. The reset spring can cushion the impact of inserting the connector into the socket of the EPB product power head when the connector is inserted, and can ensure that the intermediate transmission component is reset after the detection is completed when the connector is pulled out.

[0023] The specific technical solutions and beneficial effects of the present invention will be described in detail in the following specific embodiments with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Those skilled in the art will appreciate that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.

[0033] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. For example, terms such as "upper," "lower," "left," "right," "front," and "back" that indicate orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the disclosure. They do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as limiting the disclosure.

[0034] like Figures 1 to 4 As shown in the figure, the EPB product electronic parking automatic detection device includes:

[0035] The product mounting seat 15 is used to mount the EPB product 29. The product mounting seat 15 is driven up and down by the first linear actuator, and when it rises, it presses the EPB product against the connector mounting seat 14;

[0036] The connector mounting base 14 is located above the product mounting base 15 and includes a connector connecting plate 26 for mounting a connector 27, an intermediate transmission assembly connected to the connector connecting plate 26, and a vertically mounted second linear actuator. The second linear actuator drives the connector connecting plate 26 through the intermediate transmission assembly, and the intermediate transmission assembly converts the vertical movement of the second linear actuator into a horizontal extension and retraction movement of the connector connecting plate 26. When extended, the connector 27 is inserted into the connector socket of the EPB product power head so that the pins therein contact. When retracted, the connector 27 is removed from the connector socket of the EPB product power head.

[0037] Due to space limitations, it's not possible to use a driver to directly drive the connector 27 for insertion and removal. Furthermore, using the driver to directly push the connector 27 into the product's powerhead connector would be too fast and forceful, easily impacting the connector. Therefore, a second linear actuator is mounted vertically and, through the linkage of an intermediate transmission assembly, ensures accurate insertion of the connector into the EPB product's powerhead connector. The intermediate transmission assembly also prevents the driver from directly driving the connector into the EPB product's powerhead connector, which would create significant impact.

[0038] The product output force detection mechanism includes a pressure plate 12 located above the EPB product caliper hook and a pressure sensor 18 connected to the pressure plate for detecting the output force of the EPB product. The pressure plate 12 is driven by a third linear drive to extend and retract horizontally forward and backward, and is driven up and down by a fourth linear drive, so that the pressure plate 12 is located above the EPB product caliper hook. When the connector 27 is inserted into the socket of the EPB product power head, the moving parts of the EPB product move downward and act on the pressure sensor 18 to perform product output force detection.

[0039] The pressure plate 12 is connected to the sensor pad connection plate 8 , the fourth linear actuator is the fourth cylinder 7 , and the cylinder push rod of the fourth cylinder is connected to the sensor pad connection plate 8 .

[0040] Furthermore, the fourth cylinder 7 is fixed to the sliding plate 4, which is connected to the first guide rail slider 3. The first guide rail slider 3 slides with the first linear guide 2, which is mounted on the pushing base 1. The third linear actuator is a third cylinder 5. The sliding plate 4 is connected to the cylinder mounting plate 6, and the cylinder push rod of the third cylinder 5 is fixedly connected to the cylinder mounting plate 6.

[0041] In order to limit the movement of the first guide rail slider 3, the end of the first linear guide rail 2 is connected with a guide rail slider limit plate 19. The entire mechanism is pushed onto the guide rail slider limit plate 19, i.e. the position of the test state.

[0042] The output force detection mechanism also includes a support frame 9 mounted on the sliding plate 4. A height limit plate is located on top of the support frame 9. This limit plate is connected to a height limit bolt that limits the height of the sensor pad connection plate. The height limit can be adjusted by adjusting the height limit screw.

[0043] Specifically, the pressure plate 12 is L-shaped, comprising a first horizontal portion and a first vertical portion. The sensor pad connection plate 8 is L-shaped, comprising a second horizontal portion and a second vertical portion, with the first vertical portion being fixed to the second vertical portion. A pressure sensor mounting groove is provided on the upper surface of the first horizontal portion, into which the aforementioned pressure sensor 18 is mounted. A pressure sensor pad 17 is provided above the first horizontal portion, which is press-fitted onto the pressure sensor 18.

[0044] The second vertical portion is connected to a second guide rail slider 11 , and the support frame 9 is provided with a second linear guide rail 10 . The second guide rail slider 11 is slidably engaged with the second linear guide rail 10 .

[0045] Preferably, the first linear actuator is a first air cylinder 16, and a cylinder push rod of the first air cylinder is connected to the product mounting seat 15. The product mounting seat 15 is provided with a mounting pin for positioning the EPB product 29.

[0046] refer to Figure 3 and Figure 4 As shown, the connector mounting base 14 includes a mounting base 20, and the second linear actuator is a second cylinder 13 mounted above the mounting base 20. The intermediate transmission assembly comprises an L-shaped connecting rod 22, a slide 23, and a guide rod 25. The connecting rod 22 is generally L-shaped and consists of an upper section and a lower section, with a fixed angle between them. The upper and lower sections are hinged at a fixed fulcrum at their junction. One end of the connecting rod is hinged to the cylinder push rod of the second cylinder via a pin 1 21. The slide is provided with a slide slot. The second end of the connecting rod is connected to a rolling bearing via a pin 24, which is connected to the slide slot. The guide rod 25 is connected to the slide 23 and the connector connecting plate 26, and is slidably connected to the guide sleeve. The second cylinder 13 extends and retracts, driving the connecting rod 22 to oscillate. Restricted by the guide sleeve, the guide rod 25 can only move linearly. The rolling bearing cooperates with the slide slot to convert the oscillation of the connecting rod 22 into linear motion for the guide rod 25.

[0047] Furthermore, the slide plate 23 is connected to a return spring 28, one end of which abuts the slide plate 23 and the other end is fixed. The return spring 28 can cushion the impact of inserting the connector 27 into the socket of the EPB product power head when the connector 27 is inserted, and can ensure that the intermediate transmission assembly is reset after the test is completed when the connector 27 is removed.

[0048] The specific working process of the connector mounting seat 14 is as follows:

[0049] 1. The second cylinder 13 pushes downward, the left part of the connecting rod 22 moves downward, and at the same time the right part of the connecting rod pushes the slide plate 23 to the right;

[0050] 2. The guide rod 25 connected to the slide 23 moves to the right, and the guide rod 25 drives the connector connecting plate 26 to move to the right;

[0051] 3. The connector 27 connected to the connector connecting plate 26 extends to the right and extends into the power head connector of the EPB caliper.

[0052] 4. When the test is completed and the machine returns, the second cylinder 13 is reset, and the remaining left and right mechanisms return to their original positions under the elastic action of the reset spring 28.

[0053] The electronic parking automatic detection device for EPB products of the present invention performs the following detection steps:

[0054] 1. The first cylinder 16 lifts the product mounting seat 15 and presses the EPB product tightly onto the connector mounting seat 14;

[0055] 2. The fourth cylinder 7 lifts the sensor block connecting plate 8 to the limit height of the upper limit bolt of the support frame 9;

[0056] 3. The third cylinder 5 pushes the entire mechanism onto the guide rail slider limit plate 19 through the cylinder mounting plate 6 fixed to the sliding plate 4, that is, the position of the mechanism in the test state;

[0057] 4. The fourth cylinder 7 is reset, causing the pressure plate 12 to descend so that the first horizontal portion of its bottom contacts the caliper hook;

[0058] 5. The second cylinder 13 pushes the connector 27 on the connector mounting seat 14 to the socket of the product power head, so that the PIN pins in the two contact;

[0059] 6. The equipment automatically starts the detection program;

[0060] 7. After the detection is completed, the equipment automatically stops the detection program.

[0061] 7. All mechanisms are reset.
