Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In the present disclosure, the Z direction is set for the vehicle door assembly, wherein the Z direction is the vertical direction in the normal state of the vehicle, and the direction indicated by the arrow of the Z direction is vertically upward, and vice versa. Unless otherwise specified, the orientation words such as "inner" and "outer" refer to the inner and outer relative to the outline of the component or structure itself. In addition, it should be noted that the terms such as "first", "second" and the like are used to distinguish one element from another element, and do not have sequentiality and importance. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements.

[0031] As shown in Figures 1 to 4 The first aspect of the present disclosure provides a vehicle door assembly, which comprises a vehicle door body 10, a trim panel 20 and a check device 50, wherein the vehicle door body 10 has a first drain hole 111, the trim panel 20 is connected to the vehicle door body 10 and covers the first drain hole 111, and the trim panel 20 is provided with a second drain hole 21. The check device 50 is communicated with the first drain hole 111 and / or the second drain hole 21 to allow the liquid to flow out of the vehicle in one direction from the first drain hole 111 and / or the second drain hole 21.

[0032] In the above-mentioned embodiments, the check device 50 is communicated with the first drain hole 111 and / or the second drain hole 21 to allow the liquid to flow out of the vehicle in one direction from the first drain hole 111 and / or the second drain hole 21, that is, the check device 50 can prevent the liquid from flowing into the vehicle door body 10 from the first drain hole 111 and / or the second drain hole 21. During the vehicle wading process, the liquid can be prevented from flowing into the vehicle door body 10 from the first drain hole 111 and / or the second drain hole 21 to protect the electronic elements in the vehicle door.

[0033] In addition, by providing the check device 50, the wading height of the vehicle can also be improved to meet the diversified use requirements of users, such as wading in the wild.

[0034] In addition, during the vehicle wading process with the floating water function, the liquid can be prevented from flowing into the vehicle door body 10 from the first drain hole 111 and / or the second drain hole 21, and a large amount of water entering the vehicle door body 10 can also prevent the vehicle from achieving the floating water function or affecting the floating water posture of the vehicle.

[0035] In some embodiments, the check device 50 can be communicated with the first drain hole 111 to allow the liquid to flow out of the vehicle in one direction from the first drain hole 111, that is, the liquid can be prevented from flowing into the vehicle door body 10 from the first drain hole 111, and the electronic elements in the vehicle door can be protected.

[0036] In some other possible implementations, the check device 50 is connected to the second drain hole 21 to allow liquid to flow unidirectionally out of the vehicle from the second drain hole 21. That is, the check device 50 can prevent liquid from flowing from the second drain hole 21 into the space between the trim panel 20 and the door body 10. Since the trim panel 20 covers the first drain hole 111, the check device 50 can also prevent liquid from flowing back into the door body 10, thus protecting the electronic components inside the door.

[0037] In some embodiments, the inlet end 56 of the check device 50 is connected to the first drain hole 111, and the outlet end 57 of the check device 50 is connected to the second drain hole 21, allowing liquid to flow unidirectionally from the first drain hole 111 through the check device 50 and then be discharged through the second drain hole 21. This allows liquid to be drained from the door body 10 when it is present inside the door body 10 through the first drain hole 111 and the second drain hole 21. For example, in rainy weather, rainwater may enter the door body 10 through the door glass panel. This rainwater can flow unidirectionally through the first drain hole 111 through the check device 50 and then be discharged through the second drain hole 21. When the vehicle is wading through water, the check device 50 prevents liquid from sequentially entering the door body 10 through the second drain hole 21 and the first drain hole 111, protecting the electronic components of the door and preventing a large amount of water from entering the door body 10 and affecting the vehicle's buoyancy or floating posture. Furthermore, since the check valve 50 connects between the first drain hole 111 and the second drain hole 21, the sealing requirements between the trim panel 20 and the door body 10 can be reduced. For example, the trim panel 20 can be snapped onto the door body 10 without the need for sealing between them, or with minimal sealing requirements, thereby reducing manufacturing and material costs. Even if a small amount of water enters the space between the trim panel 20 and the door body 10 through the gap, the first drain hole 111, connected to the check valve 50, prevents the water from flowing into the door body 10. Additionally, as described below, a small-area seal can be applied at the connection between the check valve 50 and the first drain hole 111, further reducing costs.

[0038] In some embodiments, the check device 50 can be configured in any suitable manner according to actual needs. For example, the check device 50 can be configured as a one-way valve, with the inlet end 56 of the one-way valve connected to the first drain hole 111 and the outlet end 57 of the one-way valve connected to the second drain hole 21.

[0039] Furthermore, in some implementations, such as Figures 2 to 4As shown, the check device 50 includes a housing 51 having a flow passage 52 between an inlet end 56 and an outlet end 57, and a check assembly 53 disposed in the flow passage 52, the check assembly 53 configured to open the flow passage 52 when liquid flows from the first drain hole 111 to the second drain hole 21, and to close the flow passage 52 when liquid flows from the second drain hole 21 to the first drain hole 111.

[0040] In the above embodiment, the check assembly 53 is configured to open the flow passage 52 when liquid flows from the first drain hole 111 to the second drain hole 21, so that water in the door body 10 can be drained out of the door body 10 through the flow passage 52 of the check device 50 and the second drain hole 21, and the check assembly 53 is configured to close the flow passage 52 when liquid flows from the second drain hole 21 to the first drain hole 111, so that water outside the door body 10 can be prevented from flowing back into the door body 10, and the electronic components in the door can be protected, and the water in the door body 10 can be prevented from affecting the float function of the vehicle or the float attitude of the vehicle, which will not be described here.

[0041] In some embodiments, the check assembly 53 can be configured in any appropriate form according to actual needs. For example, as shown in Figure 3 and Figure 4 The check assembly 53 can include a floating seal 532 and a baffle 531, the baffle 531 having a first passage 58, and the floating seal 532 having a closed position abutting the baffle 531 to close the first passage 58 and thereby close the flow passage 52, and an open position separated from the baffle 531.

[0042] In the above embodiment, when the floating seal 532 is in the closed position, the floating seal 532 abuts the baffle 531 to close the first passage 58, and when the first passage 58 is closed, the flow passage 52 of the check device 50 is closed, so that liquid flowing from the second drain hole 21 through the flow passage 52 and the first drain hole 111 of the check device 50 can be prevented from flowing back into the door body 10. When the floating seal 532 is in the open position, the floating seal 532 is separated from the baffle 531 to open the first passage 58, and when the first passage 58 is open, the flow passage 52 of the check device 50 is also open, so that liquid in the door body 10 can be drained out through the first drain hole 111, the flow passage 52 of the check device 50, and the second drain hole 21, to prevent damage to the electronic components in the door body 10 due to water accumulation in the door body 10.

[0043] In some embodiments, the first channel 58 has a flared opening that gradually widens in the direction toward the floating seal 532 at one end near the floating seal 532. The inner wall of the flared opening is configured as a sealing surface 5311. The floating seal 532 has a mating surface 5321a that seals with the sealing surface 5311. In the closed position, the mating surface 5321a is attached to the sealing surface 5311 to close the first channel 58.

[0044] In the above embodiment, the first channel 58 has a flared opening that gradually widens in the direction toward the floating seal 532 at one end. This opening can be used to guide the floating seal 532 as it moves toward the first channel 58 and fits against the sealing surface 5311. This facilitates the insertion of the floating seal 532 into the flared opening, thereby facilitating a sealing fit between the mating surface 5321a of the floating seal 532 and the sealing surface 5311 formed by the inner wall of the flared opening, so as to close the first channel 58.

[0045] In some implementations, such as Figure 3 and Figure 4 As shown, the check valve assembly 53 also includes a limiting member 533 spaced apart from the baffle 531 in the extending direction of the flow channel 52. The floating seal 532 includes a floating portion 5322 and a sealing portion 5321 connected to the floating portion 5322 and located between the baffle 531 and the limiting member 533. In the closed position, the sealing portion 5321 is attached to the baffle 531. In the open position, the sealing portion 5321 is separated from the baffle 531. The baffle 531 and the limiting member 533 define the movement area of ​​the sealing portion 5321.

[0046] In the above embodiment, the sealing part 5321 may have a mating surface 5321a. In the closed position, the mating surface 5321a on the sealing part 5321 may fit against the sealing surface 5311 at the flared opening of the baffle 531 to close the first channel 58.

[0047] In some embodiments, the sealing part 5321 may be made of a deformable soft rubber material, and the floating part 5322 may be made of a foamed material. The floating part 5322 and the sealing part 5321 may be connected and fixed by a connecting rod 5323, which fixes the floating part 5322 and the sealing part 5321 into a whole, enabling synchronous movement between the floating part 5322 and the sealing part 5321. For example, when a liquid (e.g., water) moves the floating part 5322, the floating part 5322 can move the sealing part 5321 between the baffle 531 and the limiting member 533. When the sealing part 5321 is made of a deformable soft rubber material, when the floating part 5322 moves the sealing part 5321 to adhere to the baffle 531, the sealing part 5321 is compressed and deformed to form a seal.

[0048] Further, when the end of the first channel 58 close to the limiting member 533 is formed with a trumpet mouth gradually expanding in the direction towards the floating sealing member 532, the sealing part 5321 can be configured as a conical shape, the side surface of the conical sealing part 5321 can be configured as a matching surface 5321a, and when the sealing part 5321 moves towards the first channel 58, the trumpet mouth can guide the conical sealing part 5321, and the conical sealing part 5321 can make the matching surface 5321a better fit the sealing surface 5311.

[0049] It should be noted that the floating part 5322 can drive the sealing part 5321 to move. For example, when liquid (e.g., water) flows back into the flow-through channel 52 from the inlet end 56 of the check device 50, the floating part 5322 can move towards the baffle 531 under the push of the liquid, and when the floating part 5322 moves, it can drive the sealing part 5321 to move towards the baffle 531, so that in the closed position, the matching surface 5321a of the sealing part 5321 fits the sealing surface 5311 on the baffle 531, to achieve the closure of the first channel 58, and thus the closure of the flow-through channel 52, and when the inlet end 56 of the check device 50 is connected to the first drain hole 111 and the outlet end 57 is connected to the second drain hole 21, the liquid can be prevented from flowing back into the door body 10 through the second drain hole, the check device 50 and the first drain hole 111.

[0050] In the open position, the sealing part 5321 is separated from the baffle 531, the first channel 58 is opened, and thus the flow-through channel 52 of the check device 50 is connected, so that the liquid in the door body 10 can smoothly flow through the first drain hole 111, the flow-through channel 52 and the second drain hole 21 and then be discharged to the outside of the vehicle.

[0051] In some embodiments, the flow-through channel 52 includes a second flow-through section 522, the baffle 531 and the limiting member 533 are arranged along the vertical direction in the second flow-through section 522, and the sealing part 5321 moves along the vertical direction between the baffle 531 and the limiting member 533.

[0052] In the above-mentioned embodiments, the sealing part 5321 can move between the baffle 531 and the limiting part 533 under the gravity of the sealing part 5321. The baffle 531 can be located above the limiting part 533 in the vertical direction. When the liquid (for example, water) flows back into the flow passage 52 from the outlet end 57 of the check device 50, the floating part 5322 drives the sealing part 5321 to move to the closed position of the floating sealing part 532 under the driving of the liquid, and the fitting surface 5321a of the sealing part 5321 is attached to the sealing surface 5311 of the baffle 531 to close the first passage 58 and further close the flow passage 52. When there is no liquid backflow, the sealing part 5321 can be driven away from the baffle 531 by the gravity of the floating sealing part 532, so that the sealing part 5321 is in the open position of the floating sealing part 532, and the flow passage 52 is conducted.

[0053] In some embodiments, the flow passage 52 further comprises a first flow section 521, which is communicated with the top end of the second flow section 522 and arranged at an angle with the second flow section 522. The end of the first flow section 521 away from the second flow section 522 is the inlet end 56, and the bottom end of the second flow section 522 is the outlet end 57.

[0054] In the above-mentioned embodiments, the first flow section 521 and the second flow section 522 are arranged at an angle, which can facilitate the arrangement of the check device 50 between the decorative plate 20 and the vehicle door body 10 to adapt to the position between the first drain hole 111 and the second drain hole 21.

[0055] In some embodiments, the limiting part 533 arranged in the flow passage 52 can be arbitrarily structured according to actual needs. For example, as shown in Figure 3 and Figure 4 The limiting part 533 comprises a limiting plate 5330, and a plurality of through holes are arranged on the limiting plate 5330 to facilitate the flow of liquid and improve the flow conductivity of the flow passage 52.

[0056] In some embodiments, as shown in Figure 3 and Figure 4 The check device 50 further comprises a filter screen 54, which is arranged in the flow passage 52 and located on the side of the limiting part 533 away from the baffle 531. This can prevent impurities in the water from entering the position of the check assembly 53 in the flow passage 52 when the water flows back during the water process of the vehicle, and avoid affecting the normal movement of the check assembly 53.

[0057] In some embodiments, the shell 51 is clamped to the trim panel 20 and / or the door body 10, so that the shell 51 is fixedly connected to the trim panel 20 and the door body 10, to facilitate installation and reduce the number of parts. Of course, in other embodiments, the shell 51 can also be connected to the door body 10 by means of, for example, fasteners, adhesion, or the like.

[0058] In some embodiments, a seal 55 is provided at the connection between the shell 51 and the trim panel 20 and / or the door body 10, which can be used to seal the connection between the shell 51 and the trim panel 20 and / or the connection between the shell 51 and the door body 10.

[0059] It should be understood that the seal 55 can be made of foam. When the seal 55 is provided at the connection between the shell 51 and the door body 10, the seal 55 made of foam can be pre-adhered to the shell 51 at a position close to the inlet end 56, and then when the inlet end 56 of the check valve 50 is connected to the first drain hole 111, the seal 55 is fitted to the door body 10 to seal the connection between the shell 51 and the door body 10. When the seal 55 is provided at the connection between the shell 51 and the trim panel 20, the seal 55 made of foam can be pre-adhered to the shell 51 at a position close to the outlet end 57, and then when the outlet end 57 of the check valve 50 is connected to the second drain hole 21, the seal 55 is fitted to the trim panel 20 to seal the connection between the shell 51 and the trim panel 20.

[0060] In some embodiments, as shown in Figs. Figure 1 and Figure 2 The door body 10 includes a door outer panel 11 and a door inner panel 12, and a first receiving cavity 13 is formed between the door outer panel 11 and the door inner panel 12. The trim panel 20 can be fixedly connected to the door outer panel 11 by the buckle 40, and a second receiving cavity 30 can be formed between the door outer panel 11 and the trim panel 20. The first drain hole 111 is provided on the door outer panel 11, and the second drain hole 21 is provided on the trim panel 20.

[0061] When the trim panel 20 and the check assembly 53 are installed on the door outer panel 11, the check valve 50 can be pre-assembled with the trim panel 20. The outlet end 57 and / or the inlet end 56 of the check valve 50 can be provided with a clamping structure 59. When the outlet end 57 and the inlet end 56 of the check valve 50 are both provided with the clamping structure 59, the clamping structure 59 of the outlet end 57 of the check valve 50 can be used to clamp the check valve 50 to the trim panel 20. When the outlet end 57 of the check valve 50 is provided with the clamping structure 59, the outlet end 57 of the check valve 50 can be clamped to the door body 10. The clamping structure 59 can be any suitable structure, such as a jaw, for example. For example, the jaw can be inserted through the first drain hole 111 / second drain hole 21 from one side of the door outer panel 11 / trim panel 20 and then clamped on the other side.

[0062] like Figures 2 to 4 As shown, in some embodiments, the outlet end 57 of the check device 50 is provided with a snap-fit ​​structure 59, while the inlet end 56 of the check device 50 may not be provided with a snap-fit ​​structure 59. The check device 50 can be pre-assembled with the trim panel 20, that is, the outlet end 57 of the check device 50 can be pre-attached to the trim panel 20 by the snap-fit ​​structure 59, so that the outlet end 57 of the check device 50 is connected to the second drain hole 21. Then, when the trim panel 20 is installed on the outer door panel 11, the check device 50 is connected to the outer door panel 11, so that the outer door panel 11 and the inlet end 56 of the check device 50 are connected. When the trim panel 20 is fixedly connected to the outer door panel 11 by the buckle 40, the inlet end 56 of the check device 50 can be inserted into the first drain hole 111 and press-fitted with the inner wall of the first drain hole 111, so that the inlet end 56 of the check device 50 is connected to the first drain hole 111. By means of the angled arrangement between the first flow section 521 and the second flow section 522 and the limiting between the trim panel 20 and the outer door panel 11, the anti-return device 50 can be stably and fixedly connected between the trim panel 20 and the outer door panel 11.

[0063] Furthermore, in some embodiments, a seal 55 may be provided at the inlet end 56 of the check device 50, and a seal 55 may not be provided at the connection between the outlet end 57 of the check device 50 and the trim panel 20. As shown above, the seal 55 may be constructed as a sealing gasket made of foam. The sealing gasket may be pre-adheded to the housing 51 of the check device 50 and located near the inlet end 56. When the inlet end 56 of the check device 50 is connected to the first drain hole 111, the seal 55 may be fitted to the outer panel 11 of the door to seal the inner wall of the first drain hole 111 and the housing 51 of the check device 50. The inlet end 56 of the housing 51 may be press-fitted with the first drain hole 111, which will not be described in detail here.

[0064] Furthermore, when the vehicle has a floating function, the arrangement of the check device 50 allows the first receiving cavity 13 to be a relatively sealed cavity when floating, providing a larger sealed cavity for the vehicle and facilitating its floating function.

[0065] The second aspect of this disclosure provides a vehicle including a door assembly as provided in the first aspect of this disclosure. The vehicle includes, but is not limited to, a gasoline vehicle, a pure electric vehicle, and a hybrid / plug-in hybrid vehicle. The vehicle has all the beneficial effects of the aforementioned door assembly, which will not be elaborated here.
