Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment, and in particular to a spraying device. Background Technology

[0002] Automotive spray testing involves simulating a heavy rain environment and using high-pressure spray equipment to spray water all over the entire vehicle to check for water leakage inside the vehicle. This verifies the waterproof performance of the sealing strips and drainage system. After the test, quality inspectors check the interior, wiring harnesses, and other areas for water ingress to ensure compliance with waterproof standards.

[0003] Because the sunroof sealing strip can undergo slow water seepage due to slight deformation caused by vibration when the vehicle is bumpy, and the drain pipe joint can loosen and fall off under dynamic conditions, causing sudden water leakage, resulting in quality defects such as water damage to the headliner interior and short circuits, a simple spray test cannot guarantee the accuracy of the test results. A special test is required for the sunroof area. Utility Model Content

[0004] To overcome the shortcomings of simple spraying which cannot guarantee the accuracy of test results and requires special testing of the skylight location, this utility model provides a spraying device.

[0005] The technical solution of this utility model is as follows: a spraying device, including a spraying frame; the spraying frame is provided with a plurality of spraying heads; it also includes an electric push rod 1, a detection frame, a silicone baffle, a spray pipe, an electric push rod 2, a connecting frame, a shock-absorbing mechanism, and a vibration block; at least two electric push rods 1 are fixedly connected to the spraying frame; the telescopic parts of all electric push rods 1 are fixedly connected to the detection frame; the detection frame is fixedly connected to the silicone baffle; the detection frame is fixedly connected to the spray pipe; at least two electric push rods 2 are fixedly connected to the detection frame; the telescopic parts of all electric push rods 2 are fixedly connected to the connecting frame; the connecting frame is connected to the shock-absorbing mechanism; the shock-absorbing mechanism is connected to the vibration block, and the vibration block is equipped with a vibration motor; the electric push rod 1 and the electric push rod 2 are respectively connected to an external power supply, and the pneumatic push rod is connected to an external air pump.

[0006] As a further preferred embodiment, it also includes at least two pneumatic push rods fixed to the connecting frame; each pneumatic push rod telescopic section is connected to an impact block.

[0007] As a further preferred option, the pneumatic push rod and the impact block are detachably connected.

[0008] As a further preferred embodiment, the shock absorption mechanism consists of springs and connecting blocks; at least four springs are fixedly connected to the connecting frame; all springs are jointly fixedly connected to the connecting block; and the connecting block is fixedly connected to the vibration block.

[0009] As a further preferred option, a sealing cloth is also included connected to the lower part of the connecting frame to make the inside of the connecting frame sealed; the sealing cloth is connected to the vibration block and all impact blocks to ensure the sealing of the inside of the connecting frame.

[0010] As a further preferred embodiment, it also includes three rubber blocks fixed to the sealing cloth; each rubber block is connected to a corresponding vibration block and impact block.

[0011] As a further preferred option, each rubber block is detachably connected to the connecting frame, vibration block, and impact block.

[0012] This utility model has the following advantages:

[0013] The vibrating block causes the sunroof to vibrate, thus simulating the situation when the vehicle is in motion. This simulates the possibility of the sunroof sealing strip undergoing slight deformation due to vibration, leading to chronic water seepage. It also simulates the possibility of the drain pipe joint loosening and falling off under dynamic conditions, causing sudden water leakage and resulting in problems such as water seepage in the headliner interior, short circuits, or vehicle body corrosion. This increases the accuracy of the detection.

[0014] The pneumatic push rod is controlled to drive the impact block to descend rapidly and strike the sunroof glass. The sunroof glass is frequently impacted, simulating the state of the sunroof glass being impacted. Through diversified testing, the leakage prevention performance of the vehicle in actual use is guaranteed.

[0015] Due to the sealing cloth, the sprayed water is only distributed in the contact area between the sunroof and the vehicle, avoiding the impact of the vibrating block causing the sunroof to vibrate and the impact block hitting the sunroof. Attached Figure Description

[0023] Example 1

[0024] A spraying device, such as Figures 1-5 As shown, it includes a spray frame 1; the spray frame 1 is provided with a plurality of spray heads 1001;

[0025] It also includes an electric push rod 1 2, a detection frame 3, a silicone baffle 4, a spray pipe 5, an electric push rod 2 6, a connecting frame 7, a shock absorption mechanism, and a vibration block 8; the spray frame 1 is fixedly connected to two electric push rods 1 2; the telescopic parts of all electric push rods 1 2 are fixedly connected to the detection frame 3; the detection frame 3 is fixedly connected to the silicone baffle 4; the detection frame 3 is fixedly connected to the spray pipe 5; the detection frame 3 is fixedly connected to two electric push rods 2 6; the telescopic parts of all electric push rods 2 6 are fixedly connected to the connecting frame 7; the connecting frame 7 is connected to the shock absorption mechanism; the shock absorption mechanism is connected to the vibration block 8, and the vibration block 8 is equipped with a vibration motor. Through the shock absorption mechanism, the vibration of the vibration block 8 is prevented from affecting the pneumatic push rod 9 and the electric push rod 2 6, etc.; the electric push rods 1 2 and 2 6 are respectively connected to an external power supply, and the pneumatic push rod 9 is connected to an external air pump.

[0026] It also includes two pneumatic push rods 9 fixed to the connecting frame 7; each pneumatic push rod 9 has an impact block 10 connected to its telescopic part.

[0027] The pneumatic push rod 9 and the impact block 10 are detachably connected, making it easy to replace the impact block 10 with different sharpness, thereby simulating the impact of different objects and enhancing the accuracy of detection.

[0028] The shock absorption mechanism consists of springs 103 and connecting blocks 104; four springs 103 are fixedly connected to the connecting frame 7; all springs 103 are fixedly connected to the connecting block 104; the connecting block 104 is fixedly connected to the vibration block 8.

[0029] It also includes a sealing cloth 101 connected to the lower part of the connecting frame 7, so that the inside of the connecting frame 7 is sealed; the sealing cloth 101 is connected to the vibration block 8 and all the impact blocks 10 to ensure the sealing of the inside of the connecting frame 7.

[0030] It also includes three rubber round blocks 111 fixed to the sealing cloth 101; each rubber round block 111 is connected to the corresponding vibration block 8 and impact block 10 respectively. The rubber round blocks 111 can prevent the sealing cloth 101 from being located below the impact block 10 or in contact with the impact block 10 when the impact block 10 hits the sunroof. This would prevent the impact block 10 from moving up and down and hitting the sunroof, causing the impact block 10 and the sealing cloth 101 to rub against each other and damage the sealing cloth 101.

[0031] Each rubber block 111 is detachably connected to the connecting frame 7, the vibration block 8, and the impact block 10, making it easy to replace the impact block 10 and to replace the sealing cloth 101 when it is damaged.

[0032] The specific work steps are as follows:

[0033] The spray head 1001 and the spray pipe 5 are respectively connected to the external water supply equipment; the external air supply equipment is connected to the air jet pipe 102.

[0034] During the spraying operation, the production vehicle is moved below the spray frame 1, with the vehicle's sunroof directly above the inspection frame 3. Then, an external water supply device supplies water to the spray head 1001, from which water is sprayed to inspect the vehicle. Simultaneously, the electric push rod 2, through the inspection frame 3, lowers the silicone sleeve 4, spray pipe 5, electric push rod 6, connecting frame 7, and vibration block 8, ensuring the silicone sleeve 4 is in close contact with the top of the vehicle's metal parts, with the vehicle's sunroof positioned above the silicone sleeve 4. Inside, the vibrating block 8 contacts the sunroof, and then the external water supply device supplies water to the spray pipe 5, causing the spray pipe 5 to spray water onto the sunroof area of ​​the vehicle. At this time, the vibrating block 8 drives the sunroof to vibrate, so that the sunroof is in a vibrating state, thereby simulating whether the sunroof sealing strip will undergo micro-deformation due to vibration when the vehicle is moving, resulting in slow water seepage, and whether the drain pipe joint will loosen and fall off under dynamic working conditions, thus causing sudden water leakage, causing problems such as water soaking in the headliner interior and short circuits, thereby increasing the accuracy of the test.

[0035] Considering the issues of sunroof glass breaking and creating gaps due to external impacts (such as hail or tree branches), and the alteration of drainage paths caused by the displacement of the water guide channel, when the sunroof vibrates, the pneumatic push rod 9 drives the impact block 10 to rapidly descend and impact the sunroof glass, and then rises back to its original position. This process is repeated to frequently impact the sunroof glass, simulating the state of the sunroof glass being impacted. If gaps appear in the sunroof due to vibration or impact, water sprayed from the spray pipe 5 will enter the vehicle through the gaps. In addition, if the drain pipe joint becomes loose under dynamic conditions, or if the drainage path is altered due to the displacement of the water guide channel, water will also enter the vehicle. After testing, the sealing and impact resistance of the vehicle's sunroof can be determined by the workers' observation. Thus, through diversified testing, the leakage prevention performance of the vehicle during actual use can be guaranteed.

[0036] During the inspection process, the sunroof area of ​​the vehicle is covered by the inspection frame 3 and the silicone cover 4 to store water in the covered area. This allows water to drain quickly in case of gaps or other problems with the sunroof, preventing insufficient water from draining into the problem area due to the water being in a flowing state, which would make it difficult for staff to observe.

[0037] Considering that there is a large amount of water inside the detection frame 3 and the silicone sleeve 4, which makes it difficult for the vibrating block 8 to drive the sunroof to vibrate and affects the impact block 10 to impact the sunroof, before the detection frame 3 descends, the external air supply device supplies air to the jet pipe 102. The gas enters the connecting frame 7 through the jet pipe 102, causing the sealing cloth 101 to expand. When the control electric push rod 1 2 drives the detection frame 3 to descend and the silicone sleeve 4 contacts the vehicle, the control electric push rod 2 6 drives the connecting frame 7 and the sealing cloth 101 to descend. The expanded sealing cloth 101 will then contact the sunroof, and the spray pipe 5 will spray water. Due to the obstruction of the sealing cloth 101, the sprayed water is only distributed in the contact area between the sunroof and the vehicle, avoiding any impact on the vibration block 8 driving the sunroof to vibrate and the impact block 10 impacting the sunroof.

[0038] If the sealing cloth 101 is directly fixed to the vibrating block 8 and the impact block 10, the expanded sealing cloth 101 will come into contact with the vibrating block 8 and the impact block 10, causing the vibrating block 8 to rub against the sealing cloth 101 when vibrating and the impact block 10 to impact, resulting in rapid wear of the sealing cloth 101. Therefore, the rubber round block 111 plays a separating role at this time, keeping the expanded area of ​​the sealing cloth 101 away from the vibrating block 8 and the impact block 10, thereby preventing the vibrating block 8 from rubbing against the sealing cloth 101 when vibrating and the impact block 10 to impact, thus preventing rapid wear of the sealing cloth 101.

[0039] With prolonged use, the sealing cloth 101 will inevitably be damaged, and a new sealing cloth 101 will need to be replaced. Since the rubber round block 111 is detachably connected to the vibration block 8 and the impact block 10, it is convenient to replace the sealing cloth 101 when it is damaged.

[0040] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
