[0002] In the field of waterproof testing, it is crucial to test products for different levels of waterproof performance. IPX1 / 2 testing is a common level of waterproof testing. Existing IPX1 / 2 testing devices in waterproof test chambers primarily rely on manual adjustment of the drip assembly height. Operators must manually adjust the drip assembly to a distance of 20 cm from the sample on the touchscreen before the equipment can be operated.

[0003] This manual adjustment method has certain limitations. First, samples vary in shape and height. Manual operation not only increases test preparation time but also requires high operator skills and accurate distance control. However, visual distance estimation is prone to errors, affecting the accuracy of test results. Utility Model Content

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0032] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0033] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0034] In the description of this embodiment, the terms "upper" and "lower" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive distinction and do not have any special meaning.

[0035] In the field of waterproof testing, it is crucial to test products for different levels of waterproof performance. Among these, the IPX1 / 2 test is a common level of waterproof testing. Existing IPX1 / 2 testers in waterproof test chambers primarily rely on manual adjustment of the height of the drip assembly 3. Operators must manually adjust the height of the drip assembly 3 to a distance of 20 cm from the sample before the equipment can be operated. This manual operation not only increases test preparation time but also places high demands on the operator's technical skills, requiring precise distance control. Even the slightest error can affect the accuracy of the test results. Furthermore, the manual adjustment process is cumbersome, reducing test efficiency.

[0036] To solve the above problems, this embodiment provides a waterproof performance detection device. Figures 1 to 4 As shown, the waterproof performance testing device includes: a housing 1, a lifting mechanism 2, a drip assembly 3, a sample stage 5, and a distance sensor 7. The sample stage 5 is disposed within the housing 1 and connected to the inner wall of the housing 1. The sample stage 5 is used to carry the sample to be tested. The drip assembly 3 is spaced apart above the sample stage 5. The lifting mechanism 2 is disposed on the housing 1. The output end of the lifting mechanism 2 is connected to the drip assembly 3 to drive the drip assembly 3 up and down. The distance sensor 7 is used to detect the distance between the drip assembly 3 and the sample. The synergistic effect of the distance sensor 7 and the lifting mechanism 2 enables precise adjustment of the height of the drip assembly 3. The device can simulate various actual rain scenarios, improve detection accuracy and reliability, provide reliable data for waterproof performance evaluation, enable repeatable detection to reduce errors, and establish a standardized detection process. At the same time, it is convenient and efficient to operate, thereby improving detection efficiency.

[0037] The drip assembly 3 can be a shower or a drip tray. In this embodiment, the drip assembly 3 is preferably a drip tray, which is in the shape of a tray and can increase the area of dripping water, so that the sample to be tested can be evenly sprinkled with water, thereby ensuring the accuracy of the test results.

[0038] In this embodiment, if Figure 4 As shown, the distance measuring sensor 7 is disposed on the circumference of the drip assembly 3. In other embodiments, the distance measuring sensor 7 can also be disposed at other locations of the waterproof performance testing device, as long as the distance between the drip assembly 3 and the sample can be detected. There is no restriction on the specific fixed position of the distance measuring sensor.

[0039] It is worth noting that the distance measuring sensor 7 can be a laser distance measuring sensor, an ultrasonic distance measuring sensor, or an infrared distance measuring sensor, etc., and the selection of a specific type of distance measuring sensor 7 is not limited. The distance between the dripping assembly 3 and the sample refers to the distance between the dripping assembly 3 and the highest point of the sample.

[0040] In this embodiment, the lifting mechanism 2 includes a power source assembly 21, a transmission member 22, and multiple sets of lifting assemblies 23. The multiple sets of lifting assemblies 23 are arranged at intervals along the circumference of the drip assembly 3 and are connected to the drip assembly 3. The multiple sets of lifting assemblies 23 are connected to the power source assembly 21 via the transmission member 22, so that the multiple sets of lifting assemblies 23 move synchronously. The power source assembly 21 transmits power to the multiple sets of lifting assemblies 23 uniformly and synchronously through the transmission member 22. Because the multiple sets of lifting assemblies 23 are spaced apart around the circumference of the drip assembly 3 and jointly support the drip assembly 3, when they move synchronously, they can ensure that the drip assembly 3 can be lifted and lowered smoothly in the vertical direction. At the same time, a single transmission member 22 connects the multiple sets of lifting assemblies 23, ensuring the consistency of the movements of each lifting assembly 23, avoiding the adverse effects caused by asynchrony, and helping to improve the accuracy and reliability of detection.

[0041] like Figure 3 As shown, the transmission member 22 includes a first transmission member 221 and a second transmission member 222. The power source assembly 21 outputs power to the first transmission member 221. Two second transmission members 222 are symmetrically arranged on opposite sides of the first transmission member 221. The first transmission member 221 transmits the power to the two second transmission members 222. Two lifting assemblies 23 are symmetrically arranged on opposite sides of the second transmission member 222. The second transmission member 222 then transmits the power to the lifting assembly 23, which realizes the lifting and lowering of the drip assembly 3.

[0042] In other embodiments, the lifting assemblies 23 can be provided in a single group to achieve the lifting and lowering of the drip assembly 3 in a relatively simple manner; they can also be provided in two groups to synchronously lift and lower the drip assembly 3 from different positions, thereby enhancing the stability of the lifting process; they can also be provided in three or even more groups to further improve the smoothness and reliability of the lifting. The specific number of lifting assemblies 23 provided is not strictly limited; it only needs to ensure that the lifting assemblies 23 can enable the drip assembly 3 to complete the lifting and lowering action smoothly.

[0043] In other embodiments, there is no specific limitation on the number of power source components 21 and transmission components 22. Each group of lifting components 23 can be equipped with a separate power source component 21 and transmission component 22. It is only necessary to ensure the synchronization of each group of lifting components 23 during operation, so that the dripping component 3 can be lifted and lowered smoothly without causing problems such as tilting or instability due to the difference in movements between different groups of lifting components 23.

[0044] It is worth noting that the power source component 21 can be a motor, a hydraulic pump, etc., and its specific structure is not limited here. It only needs to ensure that it can drive the lifting component 23 to operate.

[0045] It is worth noting that the transmission member 22 can be a worm gear, a bevel gear or other mechanism, and its specific structure is not limited here. It only needs to ensure that the transmission direction of the power output by the power source component 21 can be changed.

[0046] It is worth noting that the lifting assembly 23 can be a worm gear and a ball screw, which changes the direction of the power through the worm gear and then achieves precise lifting and lowering motion through the ball screw; or it can be a bevel gear and a ball screw, which adjusts the transmission direction through the bevel gear and then uses the ball screw to complete the lifting and lowering operation of the drip assembly 3. The specific structure is not limited here, as long as it can ensure that the drip assembly 3 can be lifted and lowered.

[0047] In this embodiment, if Figure 4 As shown, the drip assembly 3 is provided with a water tank 4, and the water tank 4 is provided with a monitoring assembly 41 to monitor the water level in the water tank 4. The provision of the water tank 4 can provide a stable water source. By monitoring the water level through the monitoring assembly 41, the water supply can be adjusted in time to ensure a stable drip flow rate. Abnormalities in the water level of the water tank 4 may cause unstable drip flow rate and affect the detection results. The application of the monitoring assembly 41 can detect water level problems in a timely manner, take corresponding measures, and ensure the reliability of the detection. In other embodiments, the water tank 4 can also be set at other positions of the housing 1. It is only necessary to ensure that the water tank 4 can supply water to the drip assembly 3, and its specific installation position is not limited.

[0048] In this embodiment, the monitoring component 41 uses radar to monitor water level changes. In other embodiments, the monitoring component 41 can also use sensors, liquid level gauges, etc. to monitor water level changes. The specific selection of the monitoring component 41 is not specifically limited here.

[0049] In this embodiment, if Figure 4 As shown, the sample table 5 is provided with a sample holder 51, the top surface of which is inclined. The inclined top surface of the sample holder 51 can promote the rapid flow of water, effectively preventing water accumulation on the sample surface. Once water accumulates on the sample surface, it will greatly affect the accurate judgment of the product's waterproof performance. Through this design, it can be ensured that the water on the sample surface is always in a dynamic flow state during the testing process, which is closer to the state in actual use, thereby significantly improving the accuracy of the test.

[0050] In this embodiment, if Figure 4 As shown, the waterproof performance testing device also includes multiple camera assemblies 6, at least some of which are circumferentially spaced apart on the sample stage 5. This arrangement can monitor the sample status in all directions, record the testing process in real time, improve test accuracy, and provide assurance for test traceability.

[0051] It is worth noting that the camera components 6 can be set to two groups, three groups or four groups, etc. There is no specific restriction on the number of camera components 6 installed, as long as it ensures all-round monitoring of the sample.

[0052] Specifically, if Figure 4 and Figure 5 As shown, the camera assembly 6 includes a bracket 63, a camera 61, and a fourth fastener. The bracket 63 is arranged on the sample stage 5. The bracket 63 includes two fixed plates 635 arranged at intervals. The fixed plates 635 are provided with first mounting holes 631. The camera 61 is arranged between the two fixed plates 635 and is rotatably connected to the first mounting holes 631 of the two fixed plates 635. The fourth fastener passes through the first mounting hole 631 and is rotatably connected to the camera 61. The camera 61 is rotatably connected to the first mounting holes 631 of the fixed plates 635, allowing the inspector to adjust the shooting angle of the camera 61 according to actual needs to adapt to the monitoring requirements of samples of different shapes. The fourth fastener serves as the rotation axis to enable the camera 61 to rotate relative to the bracket 63. At the same time, the fourth fastener can also be fixed after the relative position of the camera 61 and the bracket 63 is adjusted.

[0053] Furthermore, if Figure 4 and Figure 5As shown, the camera assembly 6 also includes a first fastener. A first adjustment hole 632 is provided around the first mounting hole 631. The first fastener passes through the first adjustment hole 632 and is connected to the camera 61. When the camera 61 rotates relative to the bracket 63, the first fastener can slide within the first adjustment hole 632. The first fastener is configured to lock the relative position between the camera 61 and the bracket 63. This arrangement further ensures the flexibility and stability of angle adjustment. After adjusting to the appropriate angle, the inspector can lock the relative position between the camera 61 and the bracket 63 using the first fastener, preventing the camera 61 from shifting due to vibration or other factors during the inspection process, ensuring a continuous and stable monitoring effect.

[0054] In some embodiments, at least one side of the first adjustment hole 632 is an arc and the arc is coaxial with the first mounting hole 631. The first fastener slides against the arc of the first adjustment hole 632 and locks the camera 61 and the bracket 63. Figure 5 As shown, the first adjustment hole 632 is configured as an arc-shaped long hole, and both sides of the first adjustment hole 632 are arcs arranged coaxially with the first mounting hole 631, and two first adjustment holes 632 are provided around the first mounting hole 631. The first fastener slides close to the arcs on both sides of the first adjustment hole 632 to adjust the vertical swing angle of the camera 61 and lock the camera 61 to the bracket 63.

[0055] Specifically, if Figure 4 and Figure 5 As shown, bracket 63 also includes a base plate 636 and a second fastener. Base plate 636 is provided with a second mounting hole 633. The second fastener passes through the second mounting hole 633 and is rotatably connected to sample stage 5. This arrangement allows the entire camera assembly 6 to adjust its angle relative to sample stage 5, expanding the range of shooting angles and meeting the needs of more comprehensive monitoring of samples of various complex shapes. The second fastener serves as a rotation axis, allowing the camera assembly 6 to rotate relative to the sample stage 5. At the same time, the second fastener can also be used to fix the camera assembly 6 after adjusting its relative position to the sample stage 5.

[0056] Furthermore, if Figure 4 and Figure 5 As shown, the camera assembly 6 also includes a third fastener, and a second adjustment hole 634 is provided around the second mounting hole 633. The third fastener passes through the second adjustment hole 634 and is connected to the sample stage 5. When the bracket 63 rotates relative to the sample stage 5, the third fastener can slide in the second adjustment hole 634. The third fastener is configured to lock the relative position between the bracket 63 and the sample stage 5.

[0057] In some embodiments, at least one side of the second adjustment hole 634 is an arc and the arc is coaxial with the second mounting hole 633. The third fastener slides against the arc of the second adjustment hole 634 and locks the bracket 63 to the sample stage 5. Figure 5 As shown, the second adjustment hole 634 is configured as an arc-shaped long hole, and both sides of the second adjustment hole 634 are arcs arranged coaxially with the second mounting hole 633, and three second adjustment holes 634 are arranged around the second mounting hole 633. The third fastener slides close to the arcs on both sides of the second adjustment hole 634 to adjust the horizontal swing angle of the camera component 6 and lock the bracket 63 to the sample stage 5.

[0058] It is worth noting that the first fastener, the second fastener, the third fastener, and the fourth fastener can be screws or bolts, and their specific structures are not limited here.

[0059] In this embodiment, the camera assembly 6 is also arranged on the inner side wall of the box body 1 and is located above the sample stage 5. Figure 1 As shown, a set of camera assemblies 6 are installed on the inner side wall of the box body 1. The structure of the camera assembly 6 is not detailed here. The monitoring angle of the camera 61 can be adjusted to fully monitor the sample. Since the sample stage 5 rotates during operation of the device, the installation of a set of camera assemblies 6 on the inner side wall of the box body 1 is sufficient.

[0060] In this embodiment, the camera assembly 6 also includes a shower shield 62, which is arranged above the camera 61 and can effectively prevent water droplets, water mist and other liquids from falling directly on the camera 61, ensuring that the lens of the camera 61 remains clear and captures clear sample images, providing an accurate basis for detection.

[0061] In this embodiment, the box body 1 further includes a pulley 11, a support rod 12 and a display screen 13. The display screen 13 is used for step operation and data display. The pulley 11 and the support rod 12 are provided at the bottom of the box body 1 to facilitate the movement of the waterproof performance detection device.

[0062] The test process of the waterproof performance detection device is as follows: first, place the sample on the sample placement rack 51 of the sample stage 5, then adjust the shooting angle of the camera component 6, and then close the door of the box body 1 (not shown). Then, the waterproof performance detection device starts to run. At this time, according to the feedback information of the ranging sensor 7, the lifting mechanism 2 automatically starts to move, so that the distance between the drip component 3 and the sample stage 5 is adjusted to the set value. After the test starts, the drip component 3 starts to spray water to simulate a rain scene. During the test, the monitoring component 41 will continue to monitor the changes in the water level in the water tank 4, and the camera component 6 will shoot the status of the sample during the test until the test is completed.

[0063] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
