[0043] The sunroof assemblies of various models are prone to creating a pressure difference between the cabin drain trough where the sunroof drain pipe is located and the outside of the vehicle. When the vehicle is driving at high speeds, the cabin pressure is higher than the outside pressure, causing air to flow back from the cabin to the outside. When this backflowing air passes through the sunroof drain pipe and encounters water droplets on the inner wall of the pipe that have not been completely drained, it causes unusual noises, affecting the user experience.

[0044] In view of this, the present invention provides a device for preventing abnormal noise from skylight water pipes, which can prevent abnormal noise from occurring in the skylight water pipes without affecting the drainage function of the skylight water pipes. The device has a simple structure and an ingenious arrangement. Figures 1 to 6 This invention provides an embodiment of a device for preventing abnormal noise from skylight water pipes.

[0045] Please refer to Figures 1 to 4 The device 100 for preventing abnormal noise from the skylight water pipe b is used to be installed at the drainage end b1 of the skylight water pipe b corresponding to the vehicle body a. The device 100 for preventing abnormal noise from the skylight water pipe b includes a main body 1 and a drainage plate 2. The main body 1 is used to be installed on the vehicle body a. The main body 1 is provided with an inner cavity 11. The outer surface of the main body 1 is penetrated by a water inlet hole 1111 for the drainage end b1 to pass through. The main body 1 is also provided with an opening 1121 spaced from the water inlet hole 1111 and used to communicate with the outside; the drainage plate 2 covers the opening 1121, and the drainage plate 2 has a mounting end 21 and a rotating end 22 that are relatively arranged. The mounting end 21 is rotatably connected to the main body 1 so that the rotating end 22 can move to open the opening 1121 or close the opening 1121, wherein the rotating end 22 can move to open the opening 1121 under the push of the accumulated water c.

[0046] In the technical solution of the present invention, the outer surface of the main body 1 is provided with a water inlet hole 1111 for the drainage end b1 to pass through, and the main body 1 is also provided with an opening 1121 spaced from the water inlet hole 1111 and used to communicate with the outside; the drainage end b1 of the skylight water pipe b passes through the water inlet hole 1111, and the drainage plate 2 covers the opening 1121; when the skylight water pipe b does not need to drain, the drainage plate 2 covers the opening 1121 to close the inner cavity 11, thereby preventing wind from passing through the skylight water pipe b, effectively avoiding abnormal noise caused by wind and water droplets on the wall of the skylight water pipe b; when the drainage end b1 drains water, the accumulated water c can push the rotating end 22 to move to open the opening 1121, so that the accumulated water c can be discharged from the opening 1121 to the external environment; in this way, the device 100 for preventing abnormal noise from the skylight water pipe b can prevent abnormal noise from occurring in the skylight water pipe b without affecting the drainage of the skylight water pipe b.

[0047] In order to prevent the influence of wind on the drain plate 2, the drain plate 2 extends in the vertical direction and is arranged in the inner cavity 11 to separate the inner cavity 11 into a first cavity 111 and a second cavity 112. The upper end of the drain plate 2 forms the mounting end 21, and the lower end forms the rotating end 22; the opening 1121 is provided on the lower cavity wall of the second cavity 112; the water inlet 1111 is provided on the upper cavity wall of the first cavity 111. Figure 4 and Figure 5 In this embodiment, the drainage plate 2 is arranged in the inner cavity 11 and extends in the up-down direction to divide the inner cavity 11 into a first chamber 111 and a second chamber 112 distributed along the length direction of the inner cavity 11. When the car is driving and the sunroof water pipe b needs to be drained, the drainage end b1 is directed toward the first chamber 111 to drain water, and the water accumulates into accumulated water c in the first chamber 111. The accumulated water c pushes the rotating end 22 to rotate toward the second chamber 112 to open the opening 1121, so that the accumulated water c is discharged from the opening 1121. At this time, most of the wind will directly blow on the outer surface of the body 1, thereby avoiding the phenomenon that the drainage plate 2 is tightly against the opening 1121 due to excessive vehicle speed and excessive wind pressure, so that the drainage process proceeds smoothly. After the accumulated water c is drained, the drainage plate 2 returns to its original position and covers the opening 1121 due to the action of gravity, thereby isolating the drainage end b1 from the external environment and preventing abnormal noise from the sunroof water pipe b.

[0048] For details, please refer to Figure 3 and Figure 4In this embodiment, the main body 1 also includes a side enclosure shell 12 and a bottom plate 13 provided at the bottom of the side enclosure shell 12, the bottom plate 13 constituting the lower cavity wall of the first cavity 111, and the end surface of the bottom plate 13 facing the second cavity 112 is spaced apart from the side enclosure shell 12 to form the opening 1121; the rotating end 22 abuts against the end surface of the bottom plate 13 facing the second cavity 112. The drain board 2 extends in the up and down directions, the mounting end 21 is mounted on the body 1, and the rotating end 22 abuts against the end surface of the bottom plate 13 facing the second chamber 112, so that the second chamber 112 is used to communicate with the external environment; when the drain board 2 rotates, it is used to close or connect the first chamber 111 and the second chamber 112; so that when the rotating end 22 is pushed toward the second chamber 112 by the accumulated water c, the first chamber 111 is connected with the second chamber 112, and the accumulated water c can flow out through the opening 1121; when the rotating end 22 rotates toward the first chamber 111 due to the gravity of the drain board 2 itself and abuts against the end surface of the bottom plate 13 facing the second chamber 112, the drain board 2 stops rotating toward the first chamber 111, closing the first chamber 111 to prevent wind from entering the drainage end b1 and causing abnormal noise in the skylight water pipe b.

[0049] More specifically, refer to Figures 2 to 4In this embodiment, the body 1 further includes a partition plate 14 provided in the inner cavity 11, the partition plate 14 having a first section 141 extending horizontally and a second section 142 provided at the end of the first section 141 and extending downwardly, the first section 141 being used to be fixed to the inner wall surface of the inner cavity 11; the mounting end 21 of the drain plate 2 is rotatably mounted on the second section 142, and the mounting end 21 abuts against the side of the second section 142 toward the second cavity 112, so that the mounting end 21 stops rotating toward the first cavity 111, thereby enhancing the stability of the drain plate 2; the drain plate 2 and the partition plate 14 jointly divide the inner cavity 11 into the first cavity 111 and the second cavity 112; thereby, the height of the first cavity 111 extending in the vertical direction is higher than that of the second cavity 112, and the volume of the first cavity 111 is larger than that of the second cavity 112 chamber 112, so that the first chamber 111 has a certain space to accommodate the drainage end b1, and reduces the height of the drainage board 2 extending in the up and down directions, reduces the volume of the drainage board 2, further reduces the mass of the drainage board 2, and makes the drainage board 2 more easily pushed by the accumulated water c; a water gap 15 is defined between the second section 142 and the bottom plate 13, so that when the drainage board 2 rotates, the water gap 15 and the opening 1121 are connected; when the drainage end b1 is drained toward the first chamber 111, the accumulated water c pushes the drainage board 2 away from the first chamber 111, so that the water gap 15 is connected with the opening 1121, so that the accumulated water c flows from the first chamber 111 to the second chamber 112 through the water gap 15, and then is discharged from the second chamber 112 to the external environment through the opening 1121.

[0050] It should be noted that in the present invention, since the drainage board 2 is set to be light in mass, in this embodiment, the mass of the accumulated water c in the first chamber 111 is not limited. When the accumulated water c does not reach the water inlet hole 1111, it can push the rotating end 22 to rotate toward the second chamber 112 for drainage. At this time, most of the wind blows directly on the outer surface of the main body 1, and a small amount of wind enters the second chamber 112 from the opening 1121. The water gap 15 is used for drainage, so there is almost no abnormal sound in the skylight water pipe b.

[0051] In this embodiment, referring to Figure 3The side of the drain plate 2 facing the first chamber 111 is also provided with a felt 3, which can reduce or eliminate the noise generated by the drain plate 2 colliding with the bottom plate 13 when it rotates and returns to the first chamber 111. Furthermore, when a small amount of water accumulates in the first chamber 111, preventing the drain plate 2 from being pushed, the drain plate 2 closes the water-passing gap 15 due to gravity. The present invention does not limit the amount of accumulated water, as long as it is insufficient to push the drain plate 2 to rotate. The felt 3 can also absorb excess water in the first chamber 111, preventing abnormal noise caused by excess water in the first chamber 111. This effectively reduces abnormal noise and improves user comfort.

[0052] In order to facilitate the outflow of accumulated water c from the water gap 15, in one embodiment, the drainage board 2 is tilted toward the second chamber 112 in a top-to-bottom direction, thereby increasing the pressure of the drainage board 2 against the bottom plate 13, preventing the drainage board 2 from shaking due to the shaking of the car during driving, and improving stability.

[0053] In another embodiment, the bottom plate 13 is tilted from top to bottom toward the opening 1121 , thereby facilitating the flow of the accumulated water c toward the second chamber 112 and outflowing from the opening 1121 , thereby accelerating drainage.

[0054] The above two related technical features can be set either one or at the same time. Setting them at the same time will have a better effect, which can not only increase the stability of the drainage board 2, but also speed up the discharge of the accumulated water c.

[0055] It should be noted that, in the present invention, reference Figures 1 to 4 , multiple sheet metals are enclosed to form a receiving groove a1 with a notch facing the outside of the vehicle body a, and the device 100 for preventing abnormal noise from the sunroof water pipe b is installed in the receiving groove a1, and when the device 100 for preventing abnormal noise from the sunroof water pipe b is installed, the position relationship between the notch of the first chamber 111 and the second chamber 112 and the receiving groove a1 is not restricted. In this embodiment, the second chamber 112 is arranged close to the notch of the receiving groove a1, so that the accumulated water c discharged from the opening 1121 can be smoothly discharged to the external environment, reducing contact with the vehicle body a.

[0056] Reference Figure 2 and Figure 4In this embodiment, the plurality of sheet metals include a first peripheral side sheet metal a2, and the first peripheral side sheet metal a2 is provided with a mounting hole a3 extending along the length direction of the inner cavity 11; the device 100 for preventing abnormal noise of the skylight water pipe b also includes a mounting structure 4, and the mounting structure 4 includes a plurality of first mounting members 41 and a plurality of second mounting members 42.
