Description

Technical Field

[0001] This invention relates to the field of new energy vehicle testing technology, and more specifically, to a rain test device for new energy vehicle components. Background Technology

[0002] With the rapid development of the new energy vehicle industry, vehicle safety, reliability, and durability have become the focus of consumers' attention. Since the powertrain and sunroof of new energy vehicles are typically located at the bottom and top of the vehicle, they are frequently affected by rain; therefore, the waterproof and sealing performance of new energy vehicle components is crucial.

[0003] In existing technologies, common rain test devices typically employ fixed spray pipes, which spray water by arranging several nozzles above or around the test piece. The spray angle and spray position of the aforementioned spray pipes are usually fixed, making it difficult to simulate the multi-angle impact of rainwater on components under different driving speeds, wind directions, and road conditions. A single vertical spray cannot comprehensively detect the sealing condition of components under complex stress conditions, resulting in deviations between test results and actual usage environments, and making it easy to miss detections.

[0004] To address this, we propose a rain test device for new energy vehicle components. Summary of the Invention

[0005] This invention provides a rain test device for new energy vehicle components, which solves the technical problems in related technologies where the spray angle and spray position of the spray pipe are usually fixed, making it difficult to simulate the multi-angle impact of rainwater on components under different driving speeds, wind directions and road conditions. The single vertical spray is also difficult to comprehensively detect the sealing condition of components under complex stress conditions, resulting in deviations between the test results and the actual use environment.

[0006] This invention provides a rain testing device for new energy vehicle components, comprising a test chamber with an opening on one side; a support platform disposed inside the test chamber for supporting the component under test; multiple clamping assemblies disposed on the support platform for fixing the component under test to the support platform; an environmental simulation assembly disposed inside the test chamber, including a spray assembly disposed on the upper side of the support platform, comprising a U-shaped frame with an upward opening, comprising two parallel longitudinal beams and a crossbeam fixedly connected to the bottom of the two longitudinal beams; a water spray pipe with one end passing through the crossbeam and connected to an external water source; an air jet pipe concentrically disposed on the outer side of the water spray pipe, forming an air cavity between the air jet pipe and the outer wall of the water spray pipe, the side of the air cavity away from the support platform being sealed and connected to an external air source; and a power assembly disposed inside the test chamber for adjusting the position of the spray assembly on the horizontal plane.

[0007] As a further improvement of the present invention, the rain test device for new energy vehicle parts also includes a flexible sealing gasket, which is disposed on the top of the support platform and is used to seal the bottom of the part to be tested to simulate the sealed state inside the vehicle.

[0008] As a further improvement of the present invention, the power assembly includes a cross module, which includes a slider connected to the slanted frame.

[0009] As a further improvement of the present invention, a pair of ear plates are fixedly connected to the bottom of the slider, and a rotating shaft is fixedly connected between the two ear plates. The tops of the two longitudinal beams are rotatably connected to the rotating shaft. The environmental simulation component also includes an angle adjustment component, which includes a frame and a motor. The frame is fixedly connected to the slider, the motor is fixedly connected to the frame, and the output end of the motor is fixedly connected to one end of the rotating shaft.

[0010] As a further improvement of the present invention, a plurality of the clamping assemblies are arranged in a circular array about the center of the support platform. Each clamping assembly includes a support column disposed on the support platform; a Hooke hinge, one end of which is fixedly connected to the top of the support column; and a cylinder, the cylinder body of which is fixedly connected to the other end of the Hooke hinge.

[0011] As a further improvement of the present invention, a rubber pad is fixedly connected to the telescopic end of the cylinder, and the rubber pad is used to contact the part to be tested.

[0012] As a further improvement of the present invention, the environmental simulation component also includes a vibration simulation component, which includes a vibrator disposed at the inner bottom of the test chamber, the vibrator including a platform, and the support platform being fixedly connected to the top of the platform.

[0013] As a further improvement of the present invention, the rain test device for new energy vehicle components also includes a height adjustment component, which includes a lifting plate, the lifting plate being disposed inside the test chamber, and the cross module being disposed on the lower side wall of the lifting plate; a plurality of cylinders two, the plurality of cylinders two being spaced apart, the cylinder body of the cylinder two being fixedly connected to the inner top of the test chamber, the extension and retraction direction of the extension and retraction end of the cylinder two being along the vertical direction, and its extension and retraction end being fixedly connected to the upper surface of the lifting plate.

[0014] As a further improvement of the present invention, the air chamber is provided with a plurality of swirling plates, which are arranged in a ring array about the axis of the water spray pipe, so that the airflow ejected from the air chamber generates a tangential velocity.

[0015] As a further improvement of the present invention, the spray assembly further includes an annular shell, which concentrically wraps around the outer wall of the jet pipe and forms an annular chamber with the outer wall of the jet pipe. The annular shell has a plurality of air holes I arranged in a ring array about its axis, which communicate with the annular chamber. All of the plurality of air holes I are connected to an external air source. The jet pipe has a plurality of air holes II arranged in a ring array about its axis, which communicate with both the annular chamber and the air chamber.

[0016] The beneficial effects of this invention are as follows: 1. This invention constructs a coupled test field of rain and vibration through an environmental simulation component, breaking through the limitations of traditional static rain showers. High-pressure air forms a spiral airflow through a swirl plate, atomizing the water flow into a jet with rotational kinetic energy, simulating the oblique impact of wind and rain when a vehicle is traveling at high speed. The vibration simulation component synchronously reproduces the bumps of driving, stimulating potential dynamic seal failure. The cross module and the angle adjustment component work together to realize the three-dimensional trajectory movement of the spray, thus more closely matching the real working conditions and improving the accuracy of the test.

[0017] 2. This invention, by setting a flexible sealing gasket on the top of the support platform, can better simulate the sealing state of the part under test when it is installed in the whole vehicle. When the part under test is placed on the flexible sealing gasket, the gasket can fill the tiny gap between the bottom surface of the part and the support platform through elastic deformation, forming a reliable bottom sealing barrier. This effectively prevents test water from seeping in from non-test areas, avoids interference with test results due to bottom leakage, and improves the accuracy of sealing performance evaluation. Moreover, the flexible sealing gasket can be adapted to parts of various shapes, improving the versatility of the test. Attached Figure Description

Detailed Implementation

[0020] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0021] like Figures 1-11 As shown, the rain test device for new energy vehicle components is mainly used to test the waterproof and sealing performance of components of new energy vehicles, such as battery pack casings, headlights, or sunroof components. This embodiment can be illustrated using the sunroof component as an example.

[0022] A rain test device for new energy vehicle components includes a test chamber 1, a support platform 2, multiple clamping components 3, and an environmental simulation component 4.

[0023] The test chamber 1 primarily serves as a mounting and support structure, providing a carrier for the corresponding components and also acting as an environmental isolation unit. The support platform 2 mainly supports the part under test, thereby improving its stability during testing. Multiple clamping components 3 are used to fix the part under test onto the support platform 2, further enhancing its stability during testing. The environmental simulation component 4 is primarily used to simulate actual rainwater conditions.

[0024] Specifically, such as Figure 1 As shown, an opening is provided on one side of the test chamber 1, through which the operator can put the part to be tested into the test chamber 1 or take the part to be tested out of the test chamber 1.

[0025] As an optional embodiment, such as Figure 11 As shown, a door panel 9 can be installed at the opening of the test chamber 1, and a drain outlet is provided at the bottom of the test chamber 1. The door panel 9 is used to seal the opening, thereby separating the internal environment of the test chamber 1 from the external environment, reducing interference with the testing process of the test part in the external environment, and preventing water inside the test chamber 1 from spraying to the outside through the opening during testing.

[0026] In addition, such as Figure 1 As shown, the support platform 2 is located inside the test chamber 1 and is mainly used to support the part to be tested.

[0027] A flexible sealing gasket 5 is fixedly connected to the top of the support platform 2. The flexible sealing gasket 5 can be made of aging-resistant and highly elastic rubber or silicone material. When the part under test is placed on the support platform 2, the flexible sealing gasket 5 will elastically deform and fill the tiny gap between the bottom surface of the part under test and the support platform 2. This design can simulate the sealing state achieved by sealing strips or sealant when the part under test is actually installed on the vehicle body, preventing test water from seeping in from the bottom of the part under test, thereby improving the accuracy of the test results.

[0028] It should be noted that the flexible sealing gasket 5 is used to simulate the sealing interface of the part under test in the vehicle installation state, or to seal the non-test process holes at the bottom of the part under test.

[0029] In addition, such as Figure 1 and Figure 5 As shown, multiple clamping components 3 are provided on the support platform 2. The multiple clamping components 3 are arranged in a circular array about the center of the support platform 2 so as to apply clamping force to the part to be tested from multiple directions.

[0030] Specifically, each clamping assembly 3 includes a support column 31, a Hooke hinge 32, and a cylinder 33. The support column 31 is vertically fixedly connected to the support platform 2, mainly serving a supporting function. One end of the Hooke hinge 32 is fixedly connected to the top of the support column 31, and the other end is fixedly connected to the cylinder body of the cylinder 33. The telescopic end of the cylinder 33 points towards the center area of ​​the support platform 2.

[0031] In use, when it is necessary to fix the part to be tested, the telescopic end of the control cylinder 33 extends, so that its telescopic end presses against the side wall or top edge of the part to be tested. Due to the presence of the Hooke hinge 32, the cylinder 33 can swing freely within a certain angle range, which allows the cylinder 33 to adapt to the tilt angle or irregular shape of the surface of the part to be tested, ensuring that the telescopic end of the cylinder 33 can contact the surface of the part to be tested.

[0032] As an optional embodiment, such as Figure 5 As shown, a rubber pad 331 is fixedly connected to the telescopic end of cylinder 33. It should be noted that the rubber pad 331 is flexible. When the telescopic end of cylinder 33 causes the rubber pad 331 to contact the surface of the part under test, the rubber pad 331 can deform to better conform to the surface of the part under test, thereby increasing the clamping area and improving the stability of the part. Furthermore, this flexible clamping method can avoid indentations or scratches caused by rigid clamps to the surface of the part under test, thus protecting the part.

[0033] In addition, such as Figure 1 and Figure 2 As shown, the environmental simulation component 4 is used to generate simulated rainwater and control its spraying state, while simulating the vibration of a vehicle in motion. The environmental simulation component 4 mainly includes a spray component 41, a power component 42, an angle adjustment component 43, and a vibration simulation component 44.

[0034] like Figure 4 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the spray assembly 41 is disposed on the upper side of the support platform 2 and is used to spray water and air onto the part to be tested.

[0035] The spray assembly 41 includes a U-shaped frame 411, a water spray pipe 412, and an air spray pipe 413. The U-shaped frame 411 has an upward-facing opening and consists of two parallel longitudinal beams and a crossbeam. The crossbeam is fixedly connected to the bottom of both longitudinal beams, forming a stable frame structure. One end of the water spray pipe 412 passes through the crossbeam and is connected to an external water source via a swivel joint or hose for supplying test water. It should be noted that the water spray pipe 412 is fixedly connected to the crossbeam, and a solenoid valve 415 is installed on the water spray pipe 412.

[0036] The jet pipe 413 is concentrically fitted on the outside of the water spray pipe 412, and an annular air chamber 414 is formed between the inner wall of the jet pipe 413 and the outer wall of the water spray pipe 412. The top of the air chamber 414, that is, the side away from the support platform 2, is sealed and fixedly connected to the outer wall of the water spray pipe 412 and is connected to an external air source for introducing high-pressure compressed air into the air chamber 414.

[0037] Furthermore, such as Figure 6 and Figure 10 As shown, multiple swirl plates 7 are fixedly connected inside the air chamber 414. The multiple swirl plates 7 are arranged near the outlet of the air chamber 414, and the multiple swirl plates 7 are arranged in a ring array about the axis of the water spray pipe 412.

[0038] When compressed air enters the air chamber 414, the swirl plate 7 guides the airflow to generate a tangential velocity component, causing the airflow to form a high-speed spiral motion within the air chamber 414. When this spiral airflow is ejected from the outlet of the jet pipe 413, it strongly cuts and disturbs the water flow ejected from the water spray pipe 412, atomizing it into fine water droplets or forming a jet with a specific rotational speed, thereby improving the uniformity of the spray coverage and the realism of the simulation.

[0039] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, the spray assembly 41 also includes an annular housing 8. The annular housing 8 concentrically wraps around the outer wall of the jet pipe 413, forming an annular chamber 81 between the annular housing 8 and the outer wall of the jet pipe 413. Multiple air holes 82 are arranged in a ring array about its axis on the annular housing 8. These air holes 82 can be connected to an external air source through pipes. It should be noted that each pipe is equipped with a solenoid valve 416. Simultaneously, multiple air holes 4131 are arranged in a ring array about its axis on the wall of the jet pipe 413. These air holes 4131 connect both the annular chamber 81 and the air chamber 414.

[0040] During operation, compressed air from an external air source first enters the annular chamber 81. Since the annular chamber 81 is a ring-shaped pressure-equalizing space, the airflow entering from multiple directions can balance the pressure here. Subsequently, the airflow enters the air chamber 414 through the air holes 4131 evenly distributed along the circumference. This allows the compressed air to enter the air chamber 414 evenly from the circumference, avoiding the airflow eccentricity caused by the traditional single-sided air intake method, thereby improving the symmetry and uniformity of the spray.

[0041] In addition, such as Figures 2-4As shown, the power assembly 42 is used to adjust the position of the spray assembly 41 on the horizontal plane. The power assembly 42 includes a cross module 421, which is a prior art device capable of linear movement in two vertical directions, the X and Y axes; its detailed structure is not shown. The bottom of the cross module 421 includes a slider 4211, which is connected to the frame 411. By controlling the cross module 421, the slider 4211 can be driven to move the spray assembly 41 back and forth and left and right on the horizontal plane, thereby changing the position of the spray point relative to the part being measured and ensuring that the spray range can cover every corner of the part.

[0042] Furthermore, such as Figure 2 and Figure 4 As shown, the environmental simulation component 4 also includes an angle adjustment component 43. A pair of ear plates 4212 are fixedly connected to the bottom of the slider 4211, and a horizontal rotating shaft 423 is fixedly connected between the two ear plates 4212. The tops of the two longitudinal beams of the U-shaped frame 411 are rotatably connected to the rotating shaft 423, so that the spray component 41 can rotate around the rotating shaft 423.

[0043] The angle adjustment assembly 43 includes an L-shaped frame 431 and a motor 432. The frame 431 is fixedly connected to the slider 4211, and the motor 432 is fixedly mounted on the frame 431. The output end of the motor 432 is fixedly connected to one end of the rotating shaft 423, and a reducer can be configured at the output end of the motor 432. By controlling the rotation of the motor 432, the rotating shaft 423 can be driven to make the L-shaped frame 411 and the entire spray assembly 41 swing in the vertical plane, thereby adjusting the pitch angle of the spray. This allows the device to simulate the condition of rainwater impacting the part under test from a horizontal direction, such as a crosswind or at a large angle, enriching the simulation dimensions of the spray.

[0044] In addition, such as Figure 1 and Figure 2 As shown, the rain test device for new energy vehicle components also includes a height adjustment component 6. The height adjustment component 6 includes a lifting plate 61 and multiple cylinders 62. The lifting plate 61 is located inside the test chamber 1, and the mounting portion of the aforementioned cross module 421 is fixedly installed on the lower side wall of the lifting plate 61. The multiple cylinders 62 are spaced apart, with the cylinder body of each cylinder fixedly connected to the inner top of the test chamber 1. Their telescopic ends extend and retract vertically downwards and are fixedly connected to the upper surface of the lifting plate 61.

[0045] By controlling the synchronous extension and retraction of multiple cylinders 62, the lifting plate 61 and its spray assembly 41 can be moved up and down, thereby adjusting the vertical distance between the nozzle and the part to be tested. The closer the distance, the greater the impact force; the farther the distance, the wider the coverage but the smaller the impact force. The height adjustment assembly 6 can better adapt to parts to be tested at different heights and is also beneficial for adjusting the impact force of the spray.

[0046] In addition, such as Figure 2 and Figure 3 As shown, the environmental simulation component 4 also includes a vibration simulation component 44 for simulating the vibration environment during vehicle operation. The vibration simulation component 44 includes a vibrator 441, which is fixedly connected to the inner bottom of the test chamber 1. The vibrator 441 can be an electromagnetic vibrator, a mechanical vibrator 441, or a hydraulic vibrator 441, and has a platform 4411. A support platform 2 is fixedly connected to the top of the platform 4411.

[0047] During testing, the vibrator 441 is activated, causing the support platform 2, the part under test, and the clamping assembly 3 to vibrate together. This combination of vibration and rain conditions better simulates the actual working conditions of a vehicle during driving, thus enabling better testing of the rainproof performance of the part under test.

[0048] It should be noted that this embodiment also includes a controller and a camera. The camera is fixedly installed inside the test chamber 1 to monitor the working conditions inside the test chamber 1. The controller is electrically connected to the camera, multiple cylinders 33, multiple cylinders 62, motor 432, vibrator 441, external air source, external water source, solenoid valve 415, and solenoid valve 416. The controller receives and analyzes the information from the set program and the camera, and then controls the multiple cylinders 33, multiple cylinders 62, motor 432, vibrator 441, external air source, external water source, solenoid valve 415, and solenoid valve 416 to perform corresponding actions.

[0049] It should be noted that the pipes for external air and water sources, as well as the signal lines of external devices, can all be installed by slotting at appropriate locations on the test chamber 1. This is existing technology and common knowledge, and is not shown in detail in this embodiment.

[0050] The working principle of this invention is as follows: First, the operator opens the door panel 9 of the test chamber 1 and places the part to be tested on the flexible sealing gasket 5 of the support platform 2, ensuring that the bottom of the part is in close contact with the sealing gasket.

[0051] Then, the cylinders 33 of the multiple clamping components 3 are extended, and the rubber pads 331 are firmly pressed against the part to be tested by utilizing the self-adaptive ability of the Hooke hinge 32 and through manual correction, thus completing the fixation of the part to be tested.

[0052] Subsequently, the cabinet door panel 9 is closed, and the test program is started. The cylinder 62 of the height adjustment component 6 is activated to adjust the spray component 41 to a suitable height; the cross module 421 of the power component 42 and the motor 432 of the angle adjustment component 43 work together to move the spray component 41 and adjust it to the predetermined spray angle and position.

[0053] After the test begins, an external water source supplies water to the spray pipe 412, and an external air source supplies water to the annular chamber 81 and enters the air chamber 414 through the second air hole 4131, from which the air is then ejected. Compressed air, through the action of the swirl plate 7, forms a spiral airflow, which mixes with the water sprayed from the spray pipe 412 to form a rain or jet sprayed onto the part under test. At the same time, the vibrator 441 of the vibration simulation component 44 is activated, causing the part under test to vibrate at a set frequency and amplitude.

[0054] During the test, the controller can control the dynamic movement of the power component 42 and the angle adjustment component 43 to simulate the situation where the angle and position of the rainwater relative to the vehicle body are constantly changing when the vehicle is driving in the rain.

[0055] After the test, the operator removes the part under test and checks for water leakage inside to evaluate its sealing performance.

[0056] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
