[0029] like Figure 1 As shown in the coordinate system, the X, Y, and Z directions in this system are based on the vehicle coordinate system. The vehicle coordinate system is a special motion coordinate system used to describe the motion of a car. Its origin coincides with the vehicle's center of mass. When the vehicle is stationary on a level road, the X direction refers to the direction parallel to the car's direction of travel, the Y direction refers to the width of the car, and the Z direction refers to the height of the car. The front of the car in the X direction is considered the front end, and the rear of the car in the X direction is considered the rear end. The direction facing the car in the Y direction is considered the inside, and the direction away from the car is considered the outside.

[0030] from Figure 1 and Figure 2 As can be seen, the frameless car door involved in this utility model includes an inner door panel 1, an outer door panel 12 connected to the inner door panel 1 in the Y direction, a frameless window 14, and an inner water-cutting seal 2 located between the frameless window 14 and the inner door panel 1. The inner water-cutting seal 2 extends in the X direction and is snapped onto the inner door panel 1 to seal the joint between the frameless window 14 and the inner door panel 1. The inner side of the inner door panel 1 is provided with multiple mounting holes for installing electronic and electrical components.

[0031] exist Figure 1 In one embodiment, the front end of the frameless window 14 is provided with an outer trim panel 13, which is used to limit the frameless window 14 so as to cover the lower front part of the window and thus guide the opening and closing of the frameless window. Figure 1In one embodiment, the outer trim panel 13 has a triangular cross-section, and external water can be guided to the front end of the inner water-cutting seal 2 through the apex of the triangle.

[0032] like Figure 1 As shown, the frameless door drainage system proposed in this utility model includes a drain outlet 16 located at the bottom connection between the inner door panel 1 and the outer door panel 12. Optionally, the drain outlet 16 may be located at the bottom of the inner door panel 1 and / or the outer door panel 12. The drain outlet 16 connects the interior and exterior of the frameless door and is used to drain external water flowing into the frameless door out of the vehicle.

[0033] exist Figure 1 In one embodiment, the bottom of the inner door panel 1 is provided with three drain outlets 16, which are respectively located at the front, middle and rear ends of the bottom of the door in the X direction, to accelerate drainage of the frameless door. In other embodiments, the number of drain outlets 16 is not limited, and there can be multiple outlets. The location of the drain outlets 16 at the bottom of the door is also not limited, as long as it facilitates drainage.

[0034] Specifically, such as Figure 3 As shown, the front end of the internal water-cutting seal 2 is provided with at least one drain hole 31, which communicates with the drain outlet 16 to form a first drainage channel. Figure 6 The rear end of the inner water-cutting seal 2 is provided with a drainage groove 41, which is connected to the drain outlet 16 to form a second drainage channel. The frameless door drainage system of this utility model has two drainage channels at the front and rear ends, thereby improving the reliability of drainage and effectively preventing water from overflowing through the inner water-cutting seal 2 and entering the inner side of the door panel 1.

[0035] It should be noted that when applying film to the inside of the frameless window 14, water sprayed onto the window 14 will be scraped towards the inner water-cutting seal 2 during the film application process. Rainwater collected on the outside of the frameless window 14 due to seal failure during rain, as well as water from car washes, may also collect at the inner water-cutting seal 2. Therefore, by providing drainage channels at both the front and rear ends of the inner water-cutting seal 2, external water can be drained promptly, adding an extra layer of sealing and drainage to the door.

[0036] Specifically, such as Figure 2 As shown, the outer side of the inner door panel 1 and the outer door panel 12 cooperate to form a drainage cavity 15. The Y-shaped inner side of the inner door panel 1 is isolated from the outer side, thereby separating the electronic components from the drainage cavity 15. The drainage hole 31 connects to the drainage outlet 16 through the drainage cavity 15 to form a first drainage channel. External water collected at the front end of the inner water-cutting seal 2 enters the drainage cavity 15 through the drainage hole 31 and flows to the drainage outlet 16 due to gravity. It should be noted here that, combined with Figure 1As shown, the inner panel 1 of the car door is provided with mounting holes for electronic appliances. When the electronic appliances are installed in the mounting holes, they are equipped with a partition plate to isolate the electronic appliances from the drainage chamber 15.

[0037] In one embodiment, such as Figure 1 As shown, the inner water-cutting seal 2 includes an inner water-cutting body 22 and a first connecting angle 3 located at the front end of the inner water-cutting body 22. The inner water-cutting body 22 is bonded to the first connecting angle 3. The first connecting angle 3 wraps around the front end of the inner water-cutting body 22 and is snapped onto the inner door panel 1, that is, the first connecting angle 3 is located between the frameless window 14 and the inner door panel 1. Figure 3 The drain hole 31 is opened on the first corner 3 to prevent the opening from damaging the integrity and sealing of the inner water cutter body, and the first corner 3 facilitates the opening.

[0038] Furthermore, combined Figure 4 As can be seen, the first joint 3 includes a front boss 32 and a side boss 33. The front boss 32 is located at the front end of the inner water-cutting body 22 in the X direction, and the side boss 33 is located on the side of the inner water-cutting body 22 in the Y direction away from the frameless window 14. The front boss 32 and the side boss 33 are connected to form an L-shaped structure.

[0039] Combination Figure 5 As shown, the side boss 33 covers the upper Y-direction inward side of the inner water-cutting body 22, and the front end of the side boss 33 protrudes beyond the front end of the inner water-cutting body 22. Combined with... Figure 4 As shown, the front boss 32 is connected to the front end of the inner water-cutting body 22. The front boss 32 and the side boss 33 together form an L-shaped structure. The L-shaped structure surrounds and forms a groove 34. The groove 34 is located at the front end of the inner water-cutting body 22, and the drainage hole 31 is opened in the groove 34. The front boss 32 is used for external water to pass over the front boss 32 and enter the inner door panel 1 (e.g., Figure 1 The side boss 33 is used to prevent external water from entering the inner side of the door panel 1 by passing over the side boss 33 in the Y direction.

[0040] Furthermore, combining Figure 1 and Figure 4 The first corner joint 3 is integrally formed with the outer trim panel 13, and the front boss 32 is inclined on one end face near the groove 34. Thus, external water can flow from the tip of the outer trim panel 13 along the outer trim panel 13 to the front boss 32 of the first corner joint 3, and then flow into the groove 34 through the inclined surface of the front boss 32, and flow to the drain outlet 16 through the drain hole 31.

[0041] In one embodiment, such as Figure 4 As shown, the front boss 32 and the side boss 33 can be integrated, thereby preventing external water from crossing the front boss 32 and the side boss 33 and entering the inner side of the door panel 1.

[0042] from Figure 5 As can be seen, the inner water-cutting seal 2 also includes a lower lip 21 connected to the inner water-cutting body. The lower lip 21 extends toward the side close to the frameless window 14 and abuts against the outer side of the frameless window 14 to maintain the seal of the frameless window 14.

[0043] In an optional embodiment, the number of drain holes 31 is not limited and can be multiple, distributed on the first contact angle 3 at the front end of the water-cutting seal 2 to ensure unobstructed drainage. Moreover, multiple drain holes 31 can increase the drainage volume at the front end of the inner water-cutting seal 2 and accelerate drainage.

[0044] Furthermore, the aforementioned drain hole 31 can be an angled hole, thereby preventing air from entering the door through the drain hole 31 and causing impact, friction, and wind noise from air backflow with components inside the door. In other embodiments, the shape and size of the drain hole 31 are not limited, and it can also be as follows: Figure 1 The ellipse shown can also be a circle, rectangle, etc.

[0045] from Figure 1 It can also be seen that the inner water-cutting seal 2 of this utility model also includes a second connecting angle 4, which is connected to the rear end of the inner water-cutting body. The drainage groove 41 is opened on the second connecting angle 4, which can prevent the shape of the drainage groove 41 from damaging the sealing performance of the inner water-cutting body, thereby maintaining the integrity and sealing performance of the inner water-cutting body. The second connecting angle 4 also facilitates the opening of the drainage groove 41.

[0046] Specifically, a drainage channel 11 is provided at the rear end of the inner side of the door inner panel 1. The drainage channel 11 avoids the electronic and electrical components inside the door inner panel 1. The drainage channel 11 connects the drainage groove 41 and the drainage outlet 16. The drainage groove 41 connects to the drainage outlet 16 through the drainage channel 11 to form a second drainage channel. External water collected at the rear end of the inner water-cutting seal 2 enters the drainage channel 11 through the drainage groove 41 and flows along the drainage channel 11 to the drainage outlet 16 due to gravity.

[0047] Furthermore, Figure 1 Combination Figure 6 As can be seen, the drainage channel 41 is located on the inner side of the frameless window 14 in the Y direction. The second corner 4 includes a side boss 42, which is located on the side of the drainage channel 41 away from the frameless window 14. The upper end of the side boss 42 is higher than the bottom of the drainage channel 41, which is used to prevent external water from crossing the side boss 42 in the Y direction and entering the inner side of the door panel 1.

[0048] Furthermore, from Figure 1 It can be seen that the internal water-cutting seal 2 is inclined towards the front end in Z, that is, the end face of the rear end of the internal water-cutting seal 2 is higher than the end face of the front end, so as to guide the water flow to the front drain hole 31.

[0049] The frameless car door drainage system of this utility model, such as Figure 7 As shown by the downward arrow in the figure, the external water collects at the inner water-cutting body 22, flowing along the inner water-cutting body 22 towards the first front corner 3 as indicated by the right arrow in the figure; or flowing along the second rear corner 4 of the inner water-cutting body 22 as indicated by the left arrow in the figure. The water flowing towards the first front corner 3 passes through the drain hole 31 at the first corner 3 (e.g., Figure 3 As shown), Figure 7 The downward arrow below the first front corner 3 leads to water discharge through the first drainage channel. Water flowing towards the second rear corner 4 passes through the drainage trough 41 of the second corner 4 (e.g.,...). Figure 6 As shown), Figure 7 The downward arrow below the second corner 4 at the rear end leads to the discharge through the second drainage channel.

[0050] The frameless door drainage system of this utility model has a first drainage channel located at the front end of the door and a second drainage channel located at the rear end of the door. Specifically, the first drainage channel of the door drainage system of this utility model is formed by a drainage hole 31 located at the front end of the inner water-cutting seal 2, which is connected to a drain outlet 16 through a drainage cavity 15 inside the door; the second drainage channel is formed by a drainage groove 41 located at the rear end of the inner water-cutting seal 2, which is connected to a drain outlet 16 through a drainage channel 11 inside the door, thereby quickly draining the external water collected in the inner water-cutting seal 2 out of the vehicle.

[0051] The design of the two drainage channels at the front and rear ends of this utility model can effectively prevent external water from accelerating and draining in time when the waterproofing of the outer front end of the frameless window 14 fails during window tinting, automatic car washing, and rainy travel scenarios. This prevents external water from passing through the inner water-cutting seal 2 and entering the electronic and electrical components installed on the inner side of the door panel 1, thus preventing the electronic and electrical components from failing.

[0052] The frameless door drainage system of this utility model is easy to install and can be applied to various models, including but not limited to research and development models and mass-produced models, with a wide range of compatibility.

[0053] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
