Description

Technical Field

[0001] This utility model relates to the field of equipment production qualification testing technology, specifically a qualification testing device for the production of semi-trailer brake wear testing equipment. Background Technology

[0002] Trailer brake wear testing equipment is a necessary tool for most semi-trailers using disc brakes. Its working principle is as follows: Figure 1 As shown, there are typically six wear sensors connected in series. When the disc brake wears to a certain extent, it will wear down the corresponding wear sensor, causing the warning indicator light to illuminate and reminding the driver to check and replace the brake disc in time.

[0003] Because the equipment is manufactured using a high-temperature injection molding process, the high temperature and pressure during this process can easily cause solder melting and displacement of components on the circuit board. Therefore, it is essential to have a convenient and rapid way to test the quality of this equipment during the production process. Utility Model Content

[0004] The technical problem this invention aims to solve is to provide a qualification testing device for the production of semi-trailer brake wear testing equipment. During testing, pressing the control button illuminates a qualification indicator light, indicating that the semi-trailer brake wear testing equipment is qualified; conversely, illuminating a failure indicator light indicates that the equipment is unqualified. This device enables one-button rapid testing of semi-trailer brake wear testing equipment, significantly improving both the qualification rate and production efficiency.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A qualified testing device for the production of semi-trailer brake wear testing equipment includes a housing;

[0007] The upper surface of the housing is the control panel, which is equipped with control buttons, pass indicator lights, fail indicator lights, power cord interface, abnormal status indicator light interface and sensor interface assembly in sequence. All of the above electrical components are connected to the control circuit board installed inside the housing.

[0008] The power cord interface and abnormal status indicator light interface are connected to the two ends of the indicator light of the semi-trailer brake wear detection equipment under test; the sensor interface assembly is connected to the wear sensor of the semi-trailer brake wear detection equipment under test.

[0009] Using the above method, pressing the control button during testing will illuminate a pass indicator light, indicating that the semi-trailer brake wear testing equipment has passed; conversely, illuminating a fail indicator light will indicate that the equipment has failed. This device enables one-button rapid testing of semi-trailer brake wear, significantly improving both the pass rate and production efficiency.

[0010] As a preferred embodiment of a qualified testing device for the production of semi-trailer brake wear testing equipment, the sensor interface assembly consists of multiple sensor interfaces, all of which are arranged side by side on the control panel of the housing.

[0011] By adopting the above solution, in order to simultaneously detect all wear sensors in the semi-trailer brake wear detection equipment, a sensor interface assembly consisting of multiple sensor interfaces can be installed. During detection, all wear sensors can be sequentially connected to the sensor interfaces, which can greatly improve its production efficiency.

[0012] As a preferred embodiment of a qualified testing device for the production of semi-trailer brake wear testing equipment, the control panel of the housing is also provided with a group of status indicator lights connected to the control circuit board, which is located next to the sensor interface assembly.

[0013] The status indicator group consists of multiple status indicators, all of which are arranged side by side on the control panel of the housing, and each status indicator corresponds to a sensor.

[0014] To accurately identify the fault points of the wear sensors in the semi-trailer brake wear detection equipment using the above scheme, a status indicator light is installed at each sensor interface. When the status indicator light at the corresponding sensor interface is lit, it indicates that the wear sensor at that location is qualified; when the status indicator light at the corresponding sensor interface is not lit, it indicates that the wear sensor at that location is unqualified.

[0015] In a preferred embodiment of a qualified testing device for the production of semi-trailer brake wear testing equipment, the color of the qualified indicator light is different from the color of the unqualified indicator light.

[0016] Using the above solution, different light colors are used to clearly distinguish between the qualified and unqualified indicator lights; for example, the qualified indicator light is green when it is lit, and the unqualified indicator light is red when it is lit. This makes it more intuitive for staff to judge whether the product is qualified.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. Press the control button during testing. If the "pass" indicator light illuminates, it indicates that the semi-trailer brake wear testing equipment has passed; if the "fail" indicator light illuminates, it indicates that the semi-trailer brake wear testing equipment has failed. This device can complete one-button rapid testing of semi-trailer brake wear, greatly improving production efficiency while increasing the pass rate.

[0019] 2. In order to meet the requirement of simultaneous detection of all wear sensors in the semi-trailer brake wear detection equipment, a sensor interface assembly consisting of multiple sensor interfaces is installed. During the detection, all wear sensors can be connected to the sensor interfaces in sequence, which can greatly improve its production efficiency.

[0020] 3. In order to accurately determine the fault points of the wear sensors in the semi-trailer brake wear detection equipment, a status indicator light is installed at each sensor interface; when the status indicator light at the corresponding sensor interface is lit, it indicates that the wear sensor at this point is qualified; when the status indicator light at the corresponding sensor interface is not lit, it indicates that the wear sensor at this point is unqualified.

[0021] 4. To clearly distinguish between the qualified and unqualified indicator lights, different light colors are used; for example, the qualified indicator light is green when lit, and the unqualified indicator light is red when lit. This makes it more intuitive for staff to judge whether the product is qualified. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 3 As shown, a qualification testing device for the production of semi-trailer brake wear testing equipment includes a housing 1. The upper surface of the housing 1 is a control panel, on which are sequentially arranged a control button 2, a qualification indicator light 3, a failure indicator light 4, a power cord interface 5, an abnormal status indicator light interface 6, and a sensor interface assembly 7. All the above electrical components are connected to a control circuit board installed inside the housing 1. The power cord interface 5 and the abnormal status indicator light interface 6 are connected to the indicator lights of the semi-trailer brake wear testing equipment under test. The sensor interface assembly 7 is connected to the wear sensor of the semi-trailer brake wear testing equipment under test; wherein the wear sensor consists of 6 sets of sensors connected in series. When the control button 2 is pressed during testing, if the qualification indicator light 3 illuminates, it indicates that the semi-trailer brake wear testing equipment under test is qualified; if the failure indicator light 4 illuminates, it indicates that the semi-trailer brake wear testing equipment under test is unqualified. This device can complete one-button rapid testing of semi-trailer brake wear testing equipment, greatly improving production efficiency while increasing the qualification rate.

[0029] like Figure 3 As shown, the sensor interface assembly 7 consists of six sensor interfaces, all arranged side-by-side on the control panel of the housing 1, namely sensor interface 7a, sensor interface 7b, sensor interface 7c, sensor interface 7d, sensor interface 7e, and sensor interface 7f. To simultaneously detect all wear sensors in the semi-trailer brake wear detection equipment, the sensor interface assembly 7, consisting of six sensor interfaces, allows all wear sensors to be sequentially connected to the sensor interfaces during detection, significantly improving production efficiency.

[0030] like Figure 3As shown, the control panel of housing 1 also has a status indicator light group 8 connected to the control circuit board. This status indicator light group 8 is located next to the sensor interface assembly 7. The status indicator light group 8 consists of six status indicator lights: status indicator light 8a, status indicator light 8b, status indicator light 8c, status indicator light 8d, status indicator light 8e, and status indicator light 8f. All status indicator lights are arranged side-by-side on the control panel of housing 1, and each status indicator light corresponds to a sensor interface. To accurately determine the fault points of the wear sensors in the semi-trailer brake wear detection equipment, a status indicator light is installed at each sensor interface. When the status indicator light at the corresponding sensor interface is lit, it indicates that the wear sensor at that location is qualified; when the status indicator light at the corresponding sensor interface is not lit, it indicates that the wear sensor at that location is unqualified.

[0031] like Figure 2 As shown, the color of the qualified indicator light 3 is different from the color of the unqualified indicator light 4. To clearly distinguish between qualified indicator light 3 and unqualified indicator light 4, different colors are used; for example, qualified indicator light 3 is green, and unqualified indicator light 4 is red. This makes it more intuitive for staff to determine whether a product is qualified.

[0032] The operating steps of this utility model are as follows:

[0033] Before testing, power on the device and connect the six wear sensors of the semi-trailer brake wear testing equipment to sensor interfaces 7a, 7b, 7c, 7d, 7e, and 7f in sequence. Connect the two ends of the indicator lights of the semi-trailer brake wear testing equipment to power cable interface 5 and abnormal status indicator light interface 6, respectively. Then press control button 2, and the device will start automatic testing. The test results are as follows, based on the indications of each indicator light:

[0034] Scenario 1: After pressing control button 2, status indicator lights 8a-8f will light up in sequence, and finally the qualified indicator light 3 will light up. This means that all functions of the semi-trailer brake wear testing equipment are normal and it can be packaged and shipped normally.

[0035] Scenario 2: If the final failure indicator light 4 illuminates after pressing control button 2, the brake wear detection equipment for the semi-trailer under test is malfunctioning and cannot be shipped. The specific cause of the malfunction is analyzed as follows:

[0036] Fault cause 1: If none of the status indicator lights 8a-8f light up after pressing control button 2, and finally the unqualified indicator light 4 lights up, then the power line of the semi-trailer brake wear detection equipment under test is malfunctioning. You can check the connection between it and the power line interface 5 and confirm whether there is any welding abnormality in the power line of the semi-trailer brake wear detection equipment under test.

[0037] Fault Cause 2: If, after pressing control button 2, the status indicator lights 8a-8f remain lit until one of them stops lighting up, and finally the failure indicator light 4 lights up, it means that the wear sensor corresponding to the indicator light that remains lit has an abnormality. For example, if the status indicator light 8c lights up during the detection process and then stops lighting up 8d, it means that the sensor interface 7d connected to 8d has an abnormality. You can check whether there is an abnormality in the wiring harness connected to the sensor interface 7d.

[0038] Fault Cause 3: After pressing control button 2, status indicator lights 8a-8f light up in sequence, and finally the unqualified indicator light 4 lights up. This indicates that there is an abnormality in the indicator light of the semi-trailer brake wear detection device connected to the abnormal status indicator light interface 6. It is possible to check whether there is an abnormality in the wiring harness connected to the abnormal status indicator light interface 6.

[0039] In summary, this device can perform one-click rapid testing of semi-trailer brake wear detection equipment, and accurately determine the fault points of the semi-trailer brake wear detection equipment based on the operating status of each indicator light, which not only improves production efficiency but also facilitates subsequent maintenance.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
