In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0053] like Figure 1 to Figure 2 As shown, the Z direction shown in the figure is the first direction, the X direction is the second direction, and the Y direction is the third direction. The waterproof test device provided by the embodiment of the utility model includes a box body 1, a spraying mechanism 2, a driving mechanism 3 and a first position detection member 4. The box body 1 has a working chamber 11, and the working chamber 11 is provided with a positioning mechanism 12 for positioning the test piece. The spraying mechanism 2 is arranged in the working chamber 11, and the spraying mechanism 2 is used to spray water toward the test piece along the first direction. The driving mechanism 3 is arranged on the box body 1, and the driving mechanism 3 is transmission-connected to the spraying mechanism 2. The driving mechanism 3 is used to drive the spraying mechanism 2 to move along the second direction, and the first direction intersects with the second direction. The first position detection member 4 is communicatively connected to the driving mechanism 3, and the first position detection member 4 is used to detect the moving position of the spraying mechanism 2 along the second direction.

[0054] With such a configuration, when the test piece needs to undergo a waterproof test, the test piece can be placed in the working chamber 11, and the spray mechanism 2 starts to spray water toward the test piece, which will form a certain spray range. The driving mechanism 3 drives the spray mechanism 2 to move along the second direction, and the first position detection member 4 can monitor the moving position of the spray mechanism 2 along the second direction. The driving mechanism 3 adjusts its own driving force according to the moving position information of the spray mechanism 2 to drive the spray mechanism 2 to move at a uniform speed along the second direction, so that the spray mechanism 2 sprays at a uniform speed from one end of the test piece to the other end, so that the total spray range of the spray mechanism 2 can cover the entire surface of the test piece, and the sprayed water can evenly cover the surface of the test piece, reducing the situation of missed spraying or uneven spraying. The waterproof test device can test the through-type taillights, solving the problem that the waterproof test device in the related art is difficult to cover all positions on the surface of the through-type taillights, and is prone to missed spraying and uneven spraying.

[0055] In this embodiment, the test piece refers to a sample that needs to be tested for waterproofing, and the test piece can be, but is not limited to, a through-type taillight, a headlight, or a roof light. The shape or size of the box 1 can be designed according to the test requirements of the test piece. Optionally, the box 1 can be designed as a rectangular parallelepiped, and the second direction can be along the length direction of the box 1. Among them, the second direction can be selected according to the test requirements, and the second direction can be selected as horizontal or vertical. The first position detection member 4 can be configured as a position sensor or a displacement sensor, and the type of the first position detection member 4 can be selected as a proximity sensor.

[0056] like Figures 2 to 3 As shown, in some embodiments, the driving mechanism 3 includes a guide rail 31, a slider 32 and a driving member 33, and the guide rail 31 is arranged on the housing 1 and extends along the second direction. For example, the guide rail 31 can be fixedly connected to the housing 1 by bolts or magnetic connection. The slider 32 is slidably connected to the guide rail 31, and the spraying mechanism 2 is connected to the slider 32, so that the spraying mechanism 2 can slide synchronously with the slider 32. The driving member 33 is arranged on the housing 1, and the driving member 33 is transmission-connected to the slider 32. The driving member 33 can drive the slider 32 to slide along the guide rail 31, thereby driving the spraying mechanism 2 to reciprocate along the second direction to spray water on the test piece.

[0057] In this embodiment, the driving method of the driving member 33 for the slider 32 can be, but not limited to, electric, pneumatic or hydraulic driving. The top size of the guide rail 31 can be larger than the top size, so as to limit the slider 32, reduce the slider 32 from separating from the guide rail 31, and stabilize the sliding motion. For example, the cross-sectional shape of the guide rail 31 can be, but not limited to, an Ω shape or a dovetail shape. The guide rail 31 can be, but not limited to, an optical guide rail 31.

[0058] It should be noted here that the test piece has different shapes. For example, the test piece can be placed along the second direction and has a curved structure with a changing curvature. In this case, the guide rail 31 can also be designed as a curved guide rail 31, and the guide rail 31 has the same shape as the test piece.

[0059] like Figures 2 to 3 As shown, in some embodiments, the driving member 33 includes a motor 331, a plurality of gears 332 and a transmission belt 333. The motor 331 is arranged on the housing 1 so that the motor 331 is supported by the housing 1. The motor 331 can be arranged inside or outside the housing 1. The gear 332 is rotatably connected to the housing 1, and the plurality of gears 332 are arranged at intervals along the second direction, and one of the gears 332 is fixed to the output shaft of the motor 331. The transmission belt 333 is wound around the plurality of gears 332, and the transmission belt 333 is fixedly connected to the slider 32. The gears 332 support the transmission belts 333 on both sides of the motor 331 from the surface of the housing 1. The forward or reverse rotation of the motor 331 can drive the slider 32 to move forward or reversely on the guide rail 31.

[0060] Among them, a plurality of gears 332 can be arranged on both sides of the motor 331, so as to facilitate the installation and support of the transmission belts 333 on both sides of the motor 331. That is, the motor 331 can be arranged in the middle of the guide rail 31.

[0061] In this embodiment, the transmission belt 333 can be, but is not limited to, a chain or a synchronous belt. The transmission belt 333 and the gear 332 are engaged with each other through gear teeth to reduce relative sliding between the two and improve the position adjustment accuracy of the driving member 33 on the slider 32 and the injection mechanism 2. Figures 3 to 4 As shown, a plurality of support frames 13 may be provided on the box body 1, and the support frames 13 can set up the gear 332, support the gear 332 from the surface of the box body 1, and further support the transmission belt 333 from the surface of the box body 1, thereby reducing the friction between the transmission belt 333 and the box body 1.

[0062] like Figure 3 and Figure 5 As shown, in some embodiments, the spray mechanism 2 includes a spray member 21 and a water supply assembly 22. The spray member 21 is arranged on the driving mechanism 3. For example, the spray member 21 can be arranged on the slider 32 so that the spray member 21 and the slider 32 move synchronously. The spray member 21 is arranged along a first direction so that the spray member 21 sprays water toward the test object. The first direction intersects with the second direction, that is, the spray member 21 and the guide rail 31 are arranged in different directions, and there is an angle between the two. Optionally, the second direction is perpendicular to the first direction, the second direction can be horizontal, and the first direction can be vertical.

[0063] The water supply component 22 is arranged on the box body 1 so that the water supply component 22 is supported by the box body 1. The water supply component 22 is used to supply water to the injection member 21. For example, a flexible tube can be arranged between the water supply component 22 and the injection member 21. When the injection member 21 slides on the guide rail 31 with the slider 32, the flexible tube can be adaptively deformed to prevent the slider 32 from getting stuck or detached from the guide rail 31.

[0064] In this embodiment, one or more injection members 21 may be provided, and the injection member 21 is configured as a nozzle, which can spray a fan-shaped water column to form a spray range. The spray port of the injection member 21 may be, but is not limited to, a circular port, a square port, or a long strip port. When there are multiple injection members 21, the multiple injection members 21 may be arranged along a third direction, and the spray directions of the multiple injection members 21 may be along the same direction, which can increase the width of the total spray range formed by the multiple injection members 21. The third direction intersects with the second direction and the first direction in pairs, for example, the three directions may be perpendicular to each other.

[0065] In some embodiments, the spray width of the spray member 21 gradually increases from the spray member 21 to the object to be tested, that is, the spray surface of the spray member 21 may be fan-shaped, so as to increase the spray range of a single spray member 21, reduce the number of spray members 21, and cover the surface of the object to be tested. For example, there may be one spray member 21, and the spray width of the spray member 21 may be equal to or greater than the width of the object to be tested. After the spray member 21 moves along the second direction, the spray range of the spray member 21 can cover the entire surface of the object to be tested.

[0066] like Figure 3 As shown, in some embodiments, a connecting plate 34 is provided on the driving mechanism 3. For example, the connecting plate 34 can be provided on the slider 32. A lifting mechanism 35 is provided between the injection member 21 and the connecting plate 34. The lifting mechanism 35 is used to adjust the distance between the injection member 21 and the test piece along the first direction. With this arrangement, the connecting plate 34 can be arranged along the first direction to provide a lifting space for the injection member 21. The movement of the lifting mechanism 35 can drive the test piece to be tested to move along the first direction, thereby adjusting the distance between the injection member 21 and the test piece, and further changing the injection range or injection intensity of the injection member 21 on the test piece.

[0067] In this embodiment, the lifting mechanism 35 may include, but is not limited to, a combination of a cylinder, a hydraulic cylinder, or a screw nut and a motor 331, that is, the lifting mechanism 35 may drive the injection member 21, but is not limited to pneumatic, hydraulic or electric. Alternatively, the lifting mechanism 35 may also include a plurality of connection holes and bolts, wherein the plurality of connection holes are arranged along the first direction, and the injection member 21 can be fastened to different connection holes by bolts, that is, the position of the injection member 21 along the first direction can be adjusted.

[0068] like Figure 3 and Figure 5 As shown, in some embodiments, the water supply assembly 22 includes a water tank 221, a thermostat 222 and a water pump 223. The water tank 221 is used to hold water. The water tank 221 is arranged on the box body 1. The water tank 221 can be arranged inside or outside the working chamber 11 of the box body 1. The thermostat 222 is arranged in the water tank 221. The thermostat 222 is used to adjust the temperature of the water in the water tank 221, so as to adjust the temperature of the water in the water tank 221 to the preset temperature required for the test. The thermostat 222 may include one or both of a heating element and a cooling element. The water pump 223 is connected between the water tank 221 and the injection element 21. The water pump 223 can transport the water in the water tank 221 to the injection element 21, and spray water on the test piece to perform a waterproof test at a preset temperature.

[0069] Among them, the water tank 221, the thermostat 222 and the water pump 223 can be arranged inside or outside the box body 1, and the water supply component 22 can also include a protective shell, the water tank 221, the thermostat 222 and the water pump 223 are arranged in the inner cavity of the protective shell, and the protective shell can be arranged inside or outside the box body 1 and connected to the box body 1.

[0070] In this embodiment, during the test, the test piece is placed on the positioning mechanism 12, and the temperature regulating member 222 can heat the water in the water tank 221 to a preset temperature. Then the driving member 33 drives the injection member 21 to be positioned along the guide rail 31 through the slider 32, and the injection member 21 is located at the positioning origin on one side of the test piece. After the positioning is completed, the water pump 223 is started to transport the water in the water tank 221 to the injection member 21, and the driving member 33 drives the injection member 21 to move along the guide rail 31, so that the injection member 21 moves and sprays according to the guide path of the guide rail 31, so that the spray water evenly covers the entire surface of the test piece. The spray water temperature, spray pressure and moving speed of the injection member 21 can be adjusted according to the test needs.

[0071] In some embodiments, a positioning mechanism 12 is provided in the box body 1, and the positioning mechanism 12 is rotatably connected to the box body 1. The rotation axis of the positioning mechanism 12 and the box body 1 is arranged along a first direction, that is, the rotation of the positioning mechanism 12 can adjust the relative position between the test piece and the injection piece 21, so as to adjust the test piece to be tested within the injection range of the injection piece 21 to reduce leakage.

[0072] It should be noted here that the positioning mechanism 12 can generally adjust the position of the test piece before the spraying member 21 is sprayed. For example, when applied to the through-taillight test, the positioning mechanism 12 can rotate and adjust the through-taillight to be set in the same direction as the guide rail 31 along the second direction, and adjust the through-taillight to be within the spray width range of the spray member 21.

[0073] In this embodiment, a turntable can be provided at the bottom of the positioning mechanism 12, and the turntable can drive the positioning mechanism 12 to rotate. The positioning mechanism 12 can be selected and designed according to the shape of the test piece. For example, the positioning mechanism 12 can be designed to be circular, rectangular or square. A lifting platform can also be provided at the bottom of the positioning mechanism 12, and the movement of the lifting platform can drive the positioning mechanism 12 to move up and down along the first direction.

[0074] like Figure 2 As shown, in some embodiments, the driving mechanism 3 can drive the injection mechanism 2 to move back and forth along the second direction so that the injection mechanism 2 has a first extreme position and a second extreme position. The waterproof testing device also includes a second position detection component 5 and / or a third position detection component 6. The second position detection component 5 is used to cooperate with the injection mechanism 2 located at the first extreme position, and the third position detection component 6 is used to cooperate with the injection mechanism 2 located at the second extreme position. That is, the second position detection component 5 and the third position detection component 6 are arranged on both sides of the injection mechanism 2 along the second direction, and the injection mechanism 2 is limited to move within the range of the first extreme position and the second extreme position, so as to avoid the injection mechanism 2 from colliding with foreign objects and causing damage after exceeding the first extreme position and the second extreme position.

[0075] For example, the second position detection member 5 and the third position detection member 6 can be arranged on the housing 1 , and the second position detection member 5 and the third position detection member 6 can detect the relative position between the injection mechanism 2 and the housing 1 to avoid the injection mechanism 2 colliding with the housing 1 and damaging the injection member 21 .

[0076] like Figure 2 As shown, in some embodiments, the driving mechanism 3 can drive the injection mechanism 2 to reciprocate along the second direction so that the injection mechanism 2 also has an initial position located between the first extreme position and the second extreme position. The first position detection member 4 is used to cooperate with the injection mechanism 2 located at the initial position, that is, the first position detection member 4 can mark the initial position of the injection mechanism 2, so that the injection mechanism 2 moves with the initial position as the origin.

[0077] For example, the first position detection member 4 can be arranged at the end of the guide rail 31, and the slider 32 approaches or moves away from the first position detection member 4 along the second direction, and the first position detection member 4 can detect the position change of the slider 32. Moreover, the slider 32 can move with the end position of the guide rail 31 where the first position detection member 4 is located as the mark origin. Alternatively, the first position detection member 4 can be arranged on the slider 32, and the first position detection member 4 can move synchronously with the slider 32. The first position detection member 4 can use the selected position on the box 1 or the guide rail 31 as a reference point, and detect the distance between itself and the reference point to detect the position of the slider 32.

[0078] The waterproof test device can be applied to a vehicle test system. The test piece is configured as a headlight. The headlight can be, but is not limited to, a through-type taillight or a headlight. The waterproof test device can perform an IPX9K waterproof test on the headlight of the vehicle. The headlight is long, and the headlight can be placed on the positioning mechanism 12 in the same direction as the guide rail 31 along the second direction. The driving mechanism 3 drives the spraying mechanism 2 to move along the second direction and communicates with the first position detection member 4, so that the sprayed water can evenly spray and cover the surface of the headlight, reducing the possibility of missed spraying or uneven spraying.

[0079] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
