Description
Technical Field
[0001] The present application relates to the technical field of automobile trunk water spraying test, and in particular to a water spraying test device for an automobile trunk. Background Art
[0002] The spare tire cover is an important part of the car interior. It is installed in the trunk of the car to separate the spare tire compartment from the trunk, and plays the role of covering the spare tire, on-board tools and carrying items in the trunk.
[0003] With the continuous development of automobiles, multiple electronic components will be integrated in the spare tire compartment, but the property of the trunk as a storage compartment has not changed. Some spare tire covers are made of paper honeycomb boards, which contain materials such as paper / wood chips that are easy to absorb moisture. When designing spare tire covers made of honeycomb paperboard, there will be a set water absorption value, that is, how much water the spare tire cover can absorb. Testers need to use a water spray test to test whether the spare tire cover meets the set water absorption value.
[0004] In most cases of the existing water spraying test, the test personnel hold a pressure spray bottle to spray water. The pressure spray bottle will spray water through pressure so that the water is sprinkled on the spare tire cover. When the water absorption value of the spare tire cover is set, it is based on the water absorption value that the spare tire cover reaches saturation under natural flow of water. Therefore, when using the test method of a pressure spray bottle, when water penetrates into the spare tire cover, due to the existence of pressure, the water will penetrate into the spare tire cover faster than the natural penetration by gravity, so that the water absorption in the test result will be much less than the designed water absorption, thereby affecting the final test result. Utility Model Content
[0005] The technical problem to be solved by the present application is to provide a water sprinkling test device for a car trunk, which can improve the accuracy of the water sprinkling test of the spare tire cover.

[0024] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0026] like Figure 1 and 3 As shown, an embodiment of the present application provides a water sprinkling test device for a car trunk, comprising: a box body 1, which is a through structure. During the test, the box body 1 is placed on the spare tire cover. A baffle 2 is provided in the box body 1. The baffle 2 is fixedly connected to the four side walls of the box body 1 on all sides, and a plurality of first through holes 21 are provided on the baffle 2; the water sprinkling test device also includes a movable part 3, which can move relative to the baffle 2. When the movable part 3 covers the first through hole 21, the movable part 3 can prevent the water in the box body 1 from flowing out of the first through hole 21; when the movable part 3 moves relative to the baffle 2, the water in the box body 1 flows out through the first through hole 21, and the water flowing out by its own gravity soaks into the spare tire cover, simulating the situation in which a real liquid soaks into the spare tire cover when it is overturned in reality. Compared with the water sprinkling test performed by spraying with a pressure spray bottle, the accuracy of the test can be improved.
[0027] In the prior art, the spare tire cover made of honeycomb paperboard has a corresponding water absorption capacity during design, that is, how much water the spare tire cover absorbs to reach a saturated state. The test personnel need to verify the water absorption of the spare tire cover through a water sprinkling test. After the water is sprayed out with a pressure spray bottle, the water will quickly penetrate into the spare tire cover through pressure. Therefore, the amount of water required to spray the spare tire cover with a pressure spray bottle will be much less than the designed amount. For example, the water absorption capacity of the spare tire cover is 5 liters during design. When a pressure spray bottle is used, 4 liters of water is used to saturate the spare tire cover, and the error is large. The embodiment of the present application simulates the actual situation. The water flows by its own gravity to reduce the error, thereby improving the accuracy of the test.
[0028] In the prior art, testers sometimes need to test the amount of water required to test the spare tire cover for dripping, which means that liquid drips from the other end of the spare tire cover. Using a pressure spray bottle for testing will also shorten the time for the spare tire cover to drip. For example, under normal circumstances, when the spare tire cover absorbs saturated water, the spare tire cover may not drip due to the gravity of the liquid. When a pressure spray bottle is used, the water accelerates the dripping of the spare tire cover through pressure, which shortens the time required for the spare tire cover to drip, and also affects the test results. This application simulates the actual situation, reduces errors, and thus improves the accuracy of the test.
[0029] In addition, in the prior art, when the tester holds the pressure spray bottle, his arm will shake, and it is impossible to accurately ensure that the pressure spray bottle is always facing the same position. When shaking occurs, the spraying area will be uneven, which will also affect the test results. The water spraying test device of the embodiment of the present application is stationary during the test process, which can improve the accuracy of the test compared to the prior art where the tester holds the pressure spray bottle to spray.
[0030] In addition, when the tester's arm shakes, the water spraying will be uneven, which will also make the total water spraying amount uncontrollable and make the amount of water immersed in the spare tire cover plate in the same area different. The water spraying test device in the embodiment of the present application is stationary during the test, so all the water flowing out of the box body 1 is immersed in the corresponding area of the box body 1, and there will be no problem of different water spraying amounts in the test area, so that the total amount of water sprayed is controllable, and the total amount of water required for the water to penetrate into the spare tire cover plate and drip from the other end surface can be more accurately confirmed.
[0031] At the same time, the watering test device of the embodiment of the present application can be moved, which is suitable for the test scene requirements inside and outside the site. At the same time, compared with spraying with a handheld high-pressure spray bottle, the operating difficulty is greatly reduced.
[0032] Optionally, the fixed connection between the baffle 2 and the box body 1 may include an integral, non-detachable connection, such as welding, hot melting or gluing, or a detachable connection, such as a snap connection or an overlap connection.
[0033] Optionally, the diameter of the first through hole 21 may be 10 mm.
[0034] In the embodiment of the present application, the baffle plate 2 and the box body 1 can be connected by glue, or baffle plates of the same height can be set around the box body 1, and the baffle plate 2 is placed on the baffle plates for overlapping.
[0035] like Figure 1 and 2 As shown, as an implementation mode, the movable member 3 includes a movable plate 32 , and the area of the movable plate 32 can cover all the first through holes 21 , so as to prevent water from flowing out of the first through holes 21 .
[0036] like Figure 1 and 2 As shown, as an embodiment, the movable part 3 includes a handle 31, which is connected to the movable plate 32. The handle 31 extends along the end surface of the movable plate 32, so that the tester can hold the movable part 3 and move the movable part 3 relative to the baffle 2 to allow water to flow out of the first through hole 21.
[0037] Optionally, the handle 31 and the movable plate 32 may be integrally connected or detachably connected.
[0038] As an implementation mode, the area of the movable plate 32 is smaller than the area of the baffle 2, and the movable member 3 can move relative to the baffle 2 in the vertical direction. The area of the movable plate 32 is designed to be smaller than the area of the baffle 2. In this way, when the movable plate 32 is lifted, the water at this end of the movable plate 32 in the box body 1 flows out from the first through hole 21 through the gap after the movable plate 32 is lifted, thereby realizing a water sprinkling test on the spare tire cover.
[0039] Optionally, the water pressure can be adjusted by the height to which the movable plate 32 is lifted. The higher the movable plate 32 is lifted, the faster the water flows.
[0040] like Figure 1 As shown in the figure, as an embodiment, the baffle 2 is provided with a plurality of rows of first through holes 21 along a first direction, wherein the first direction refers to the adjacent Figure 1In the X-axis direction marked in the figure, the movable plate 32 is provided with a plurality of rows of second through holes 321 extending along the first direction, and the first through holes 21 in each row and the second through holes 321 in the corresponding row are in the same vertical plane; the side length of the baffle plate 2 along the first direction is greater than the side length of the movable plate 32 along the first direction, and the side lengths of the baffle plate 2 and the movable plate 32 perpendicular to the first direction are equal, and any second through hole 321 can be moved from one side of the corresponding first through hole 21 to the other side, so that the movable plate 32 can move relative to the baffle plate 2 along the X-axis direction, but cannot move along the Y-axis direction. In this way, the moving direction of the movable plate 32 is restricted so that the movable plate 32 can only move in one direction The movable plate 32 can be moved to improve the accuracy of the test, and the multiple second through holes 321 correspond to the multiple first through holes 21 respectively, which can ensure the uniformity and stability of the water outflow from the first through holes 21; in addition, during the movement of the movable plate 32, the offset position of the second through holes 321 and the first through holes 21 can be controlled to determine the size of the exposed area of the first through holes 21, so as to facilitate the adjustment of the water flow rate. When the second through hole 321 coincides with the first through hole 21, the second through hole 321 has no stop for the water, that is, the water flows out completely through the first through hole 21, and the flow rate is the fastest at this time; the test personnel can adjust the flow rate by correspondingly operating the size of the offset gap between the second through hole 321 and the first through hole 21 to reduce the difficulty of operation.
[0041] like Figure 1 As shown in the figure, as an embodiment, the baffle 2 is provided with a plurality of rows of first through holes 21 along the second direction, wherein the second direction refers to the adjacent Figure 1 In the Y-axis direction of the movable plate 32, a plurality of rows of second through holes 321 extending in the second direction are provided, and the first through holes 21 in each row and the second through holes 321 in the corresponding row are in the same vertical plane; the side length of the baffle plate 2 in the second direction is greater than the side length of the movable plate 32 in the second direction, and the side lengths of the baffle plate 2 and the movable plate 32 perpendicular to the second direction are equal, and any second through hole 321 can be misaligned or overlapped with the corresponding first through hole 21, so that the movable plate 32 can move relative to the baffle plate 2 in the Y-axis direction, but cannot move in the X-axis direction. In this way, the moving direction of the movable plate 32 is restricted so that the movable plate 32 can only be translated in one direction , and the multiple second through holes 321 correspond to the multiple first through holes 21 respectively, which can ensure the uniformity and stability of water outflow from the first through holes 21; in addition, during the movement of the movable plate 32, the offset position of the second through holes 321 and the first through holes 21 can be controlled to determine the size of the exposed area of the first through holes 21, which is convenient for adjusting the water flow rate. When the second through holes 321 coincide with the first through holes 21, that is, during the flow of water, there is no stopper of the second through holes 321, and all water flows out through the first through holes 21. At this time, the flow rate is the fastest; the test personnel can adjust the flow rate by correspondingly operating the size of the offset gap between the second through holes 321 and the first through holes 21 to reduce the difficulty of operation.
[0042] Optionally, the diameter of the second through hole 321 may be 10 mm.
[0043] As an implementation manner, the handle 31 and the movable plate 32 are detachably connected to each other, so that the handle 31 and the movable plate 32 are easily assembled.
[0044] Optionally, the movable plate 32 may be provided with a groove, and the handle 31 may be provided with a protrusion, and the handle 31 and the movable plate 32 may be detachably connected by inserting the protrusion into the groove.
[0045] As an implementation mode, the handle 31 and the movable plate 32 are integrally formed. Designing the handle 31 and the movable plate 32 as an integrally formed structure can ensure the structural stability of the movable part 3 .
[0046] Optionally, the handle 31 and the movable plate 32 can be integrally formed by gluing, hot melting or integral injection molding.
[0047] like Figure 3 As shown, as an embodiment, at least one side wall of the box body 1 is provided with a scale mark, which is indicated by setting the scale. After the test is completed, the movable plate 32 is covered on the first through hole 21 to stop the flow of water, and then the remaining water in the box body 1 is observed to determine the amount of water spraying, thereby determining the amount of water required for the spare tire cover plate water in the current area to drip from the other end surface of the spare tire cover plate.
[0048] Optionally, the amount of water required for the entire spare tire cover to drip from the other end surface of the spare tire cover can be determined by determining the ratio of the cross section of the box body 1 to the entire area of the spare tire cover. For example, if the area of the spare tire cover is four times the cross section of the box body 1, then the amount of water sprayed by a test device multiplied by four can approximately determine the amount of water required for the entire spare tire cover to drip from the other end surface of the spare tire cover.
[0049] As an implementation mode, the box body 1 is a transparent member, so that the test personnel can observe the water flow and the amount of water in the box body 1 conveniently.
[0050] Optionally, the box body 1 may be a transparent acrylic plate or a plastic part for easy movement; in some cases, glass may also be used.
