Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobiles, and in particular to a drainage pipe sheath and a vehicle. Background Art
[0002] Problems such as water leakage or abnormal noise from the car sunroof are common problems on some models, which have a great impact on user comfort. The traditional sunroof drainage path is to extend the drain pipe downward along the A-pillar to the cover, then extend through the cover to the wet area of the vehicle, and finally discharge it out of the car. However, the water outlet in this solution is usually facing the front, that is, there is a certain windward surface of the water outlet, causing the external airflow to enter the cover and the drain pipe through the water outlet, producing an abnormal sound similar to a whistle; the installation structure stability of the cover in the traditional solution is poor, which may cause the drain pipe and the cover to fall off, resulting in water leakage. Utility Model Content
[0003] In view of this, the utility model aims to provide a drainage pipe sheath and a vehicle to solve at least one of the technical problems such as abnormal noise and water leakage existing in the drainage pipe sheath in the prior art.
[0004] The utility model provides a drainage pipe sheath, comprising a first pipe section and a second pipe section, wherein the inlet end of the first pipe section is connected to the drainage pipe, the outlet end of the first pipe section is connected to the inlet end of the second pipe section, the first pipe section passes through and is connected to a first through hole provided on a lower cross beam of a windshield, the second pipe section passes through and is connected to a second through hole provided on a side beam of a wheel arch, and the outlet end of the second pipe section is communicated with the outside.
[0005] Furthermore, the outlet end of the second pipe section is arranged perpendicular to the forward direction of the vehicle.
[0006] Furthermore, the outlet end of the second pipe section is inclined downward at a first preset angle compared to a horizontal plane.
[0007] Furthermore, the inlet end of the second pipe section and the outlet end of the first pipe section are arranged at an included angle of a second preset angle, and the second preset angle is greater than 90 degrees.
[0008] Furthermore, a first clamping portion and a second clamping portion are provided on the outer surface of the first pipe section, and the first clamping portion and the second clamping portion are respectively clamped and fixed to the edges of both sides of the first through hole.
[0009] Furthermore, at least one third clamping portion is provided on the outer surface of the second pipe section, and the third clamping portion is clamped and fixed to the edge of the second through hole on the side facing the outer side of the vehicle.
[0010] Furthermore, the third clamping portion has a tapered surface that gradually narrows toward the outside of the vehicle and a clamping surface toward the inside of the vehicle, and the clamping surface is used to clamp and fix with the edge of the second through hole toward the outside of the vehicle after the tapered surface passes through the second through hole.
[0011] Furthermore, the wheel arch side beam is provided with an annular flange turned up toward the outside of the vehicle, the second through hole is formed on the inner side of the annular flange, the end of the annular flange abuts against the clamping surface, and the inner wall surface of the annular flange abuts against the conical surface.
[0012] Further, the position of the first through hole is arranged higher than the position of the second through hole.
[0013] The utility model also provides a vehicle, comprising the drainage pipe protective sheath.
[0014] The drain pipe cover in the utility model has a first pipe section that penetrates through and is connected to the first through hole of the cross beam under the windshield, and a second pipe section that penetrates through and is connected to the second through hole on the wheel arch side beam, so that the connection and fixation of the drain pipe cover is achieved through two mounting points, thereby improving the connection stability between the drain pipe cover and the vehicle body, avoiding water leakage caused by the drain pipe falling off and the like, and avoiding noise caused by the shaking of the drain pipe; and, since the outlet end of the second pipe section of the drain pipe cover guides the water flow to the external space outside the vehicle, instead of the conventional structure in which the outlet end is arranged toward the forward direction of the vehicle, whistling noise caused by airflow pouring into the outlet end of the second pipe section during driving is avoided; in addition, since the outlet end of the second pipe section directly guides the water flow to the outside, instead of the conventional structure in which the water flow is guided to the wet area of the vehicle, the risk of rust in the wet area of the vehicle is reduced.
[0015] The vehicle of the utility model has all the beneficial effects of the above-mentioned drainage pipe sheath, which will not be described in detail here.

[0027] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but are not intended to limit the present invention.
[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0029] This specification may use the phrases "in one embodiment", "in another embodiment", "in yet another embodiment" or "in other embodiments", all of which may refer to one or more of the same or different embodiments according to the present invention.
[0030] The utility model provides a drainage pipe sheath, comprising a first pipe section 1 and a second pipe section 2, wherein the inlet end of the first pipe section 1 is connected to a drainage pipe 100, the outlet end of the first pipe section 1 is connected to the inlet end of the second pipe section 2, the first pipe section 1 penetrates and is connected to a first through hole 201 provided on a lower cross beam 200 of a windshield, the second pipe section 2 penetrates and is connected to a second through hole 301 provided on a wheel arch side beam 300, and the outlet end of the second pipe section 2 is communicated with the outside.
[0031] Combination Figure 1 As shown, the relative position relationship of the drain pipe 100, the windshield lower cross beam 200, the wheel house side beam 300 and the air chamber plate 400 on the vehicle body can be seen. The air chamber plate 400 is located on the inner side of the wheel house side beam 300 and is connected to the bottom of the windshield lower cross beam 200. The drain pipe 100 extends downward from the top of the vehicle where the skylight is located, and is connected to the inlet end of the first pipe section 1 of the drain pipe sheath, thereby draining the water at the skylight to the drain pipe sheath. Figure 1 The XYZ coordinate axes are shown in the figure, where the positive direction of the X axis represents the forward direction of the vehicle, the negative direction of the X axis represents the backward direction of the vehicle, the positive direction of the Y axis represents the right side of the vehicle, the negative direction of the Y axis represents the left side of the vehicle, the positive direction of the Z axis represents the top direction of the vehicle, and the negative direction of the Z axis represents the bottom direction of the vehicle.
[0032] Specifically, combined Figure 2 and Figure 3As shown, the arrows in the figure represent the flow direction of water in the first pipe section 1 and the second pipe section 2 of the drainage pipe sheath, so that the inlet end and the outlet end of the first pipe section 1, as well as the inlet end and the outlet end of the second pipe section 2 can be seen, wherein the outlet end of the first pipe section 1 is connected to the inlet end of the second pipe section 2, the first pipe section 1 passes through the first through hole 201 opened on the lower cross beam 200 of the windshield, and can be fixed at the first through hole 201 by any means such as snap-on and screw-on, the second pipe section 2 passes through the second through hole 301 on the wheel arch side beam 300, and can be fixed at the second through hole 301 by any means such as snap-on and screw-on, so that the second pipe section 2 is equivalent to turning to the outside of the vehicle (in this embodiment, that is, the left side of the vehicle, that is, the opposite side of the Y axis in the figure), and the outlet end of the second pipe section 2 is connected to the outside, thereby guiding the water flow to the space outside the vehicle.
[0033] Furthermore, the outlet end of the second pipe section 2 is arranged perpendicular to the forward direction of the vehicle.
[0034] Combination Figure 1 , Figure 4 and Figure 5 As shown, the outlet end of the second pipe section 2 is perpendicular to the forward direction of the vehicle (i.e., the X-axis in the figure). In this way, the cross-sectional area of the outlet end of the second pipe section 2 facing the forward direction of the vehicle is zero, thereby preventing wind from entering the outlet end of the second pipe section 2 and causing noise when the vehicle is driving.
[0035] Furthermore, the outlet end of the second pipe section 2 is tilted downward at a first preset angle compared to a horizontal plane.
[0036] Combination Figure 1 , Figure 4 and Figure 5 As shown, the horizontal plane is the XY plane in the figure, and the outlet end of the second pipe section 2 is inclined downward compared to the horizontal plane (i.e., inclined in the opposite direction to the Z axis) at a first preset angle. The first preset angle is represented by β. The specific value of the first preset angle can be designed as needed, preferably in the range of β=5 to 10 degrees.
[0037] In this way, it can be ensured that the water flows smoothly through the second pipe section 2 and finally flows out to the external space outside the vehicle, thereby preventing the water flow from stagnating in the second pipe section 2.
[0038] Furthermore, the inlet end of the second pipe section 2 and the outlet end of the first pipe section 1 are arranged at an included angle of a second preset angle, and the second preset angle is greater than 90 degrees.
[0039] Combination Figure 1 , Figure 4 and Figure 5 As shown, the inlet end of the second pipe section 2 and the outlet end of the first pipe section 1 are arranged at a second preset angle, denoted by α, and the second preset angle is preferably α=95-105 degrees.
[0040] In this way, the angle between the outlet end of the first pipe section 1 and the inlet end of the second pipe section 2 is prevented from being too small, which may cause blockage there, thereby ensuring smooth water flow.
[0041] Furthermore, a first clamping portion 11 and a second clamping portion 12 are provided on the outer surface of the first pipe section 1 , and the first clamping portion 11 and the second clamping portion 12 are respectively clamped and fixed to the edges of both sides of the first through hole 201 .
[0042] Combination Figure 1 and Figure 2 As shown, a first clamping portion 11 and a second clamping portion 12 are provided on the outer surface of the first pipe segment 1. Both the first clamping portion 11 and the second clamping portion 12 are annular structures and are arranged around the first pipe segment 1, so as to ensure the connection stability of the first pipe segment 1, wherein the outer surface of the second clamping portion 12 near the outlet end of the first pipe segment 1 is conical, so that during assembly, the second clamping portion 12 can pass through the first through hole 201 with a smaller aperture, and then be clamped on a side edge of the first through hole 201 close to the front of the vehicle, and the first clamping portion 11 is clamped on a side edge of the first through hole 201 close to the rear of the vehicle, so that the first pipe segment 1 is completely fixedly installed at the first through hole 201.
[0043] In this way, the stability of the first pipe section 1 can be ensured, and shaking of the first pipe section 1 and noise can be avoided.
[0044] Furthermore, at least one third clamping portion 21 is provided on the outer surface of the second pipe section 2 , and the third clamping portion 21 is clamped and fixed to the edge of the second through hole 301 facing the outer side of the vehicle.
[0045] Combination Figure 1 and Figure 3 As shown, a plurality of adjacent third clamping portions 21 are provided on the outer surface of the second pipe section 2, and the outer surface of the third clamping portion 21 is similar to a cone, so that it can pass through the second through hole 301, and then be clamped at the edge of the second through hole 301 facing the outer side of the vehicle (i.e., the side opposite to the Y-axis), so that any third clamping portion 21 can be clamped at the second through hole 301, and the clamping position can be adjusted according to actual conditions during assembly.
[0046] In this way, the design of multiple third clamping parts 21 can facilitate assembly and adjustment, and the third clamping parts 21 can also achieve sufficient connection stability to ensure that the second pipe section 2 is firmly installed.
[0047] Furthermore, the third clamping portion 21 has a tapered surface 211 that gradually narrows toward the outside of the vehicle and a clamping surface 212 toward the inside of the vehicle, and the clamping surface 212 is used to clamp and fix with the edge of the second through hole 301 toward the outside of the vehicle after the tapered surface 211 passes through the second through hole 301.
[0048] Combination Figure 3 As shown, the third clamping portion 21 has a tapered surface 211 and a clamping surface 212. The tapered surface 211 gradually shrinks toward the outside of the vehicle (i.e., toward the opposite direction of the Y-axis), and the clamping surface 212 is a plane facing the inside of the vehicle (i.e., toward the positive direction of the Y-axis). During assembly, the second pipe section 2 extends from the inside of the vehicle through the second through hole 301 to the outside of the vehicle. Due to the design of the tapered surface 211, the third clamping portion 21 can smoothly pass through the second through hole 301, so that the clamping surface 212 can be clamped and fixed to the edge of the second through hole 301 on the opposite side of the Y-axis.
[0049] In this way, the design of the conical surface 211 allows the third clamping portion 21 to pass through the second through hole 301, and the design of the clamping surface 212 allows the third clamping portion 21 to be clamped and fixed to the edge of the second through hole 301 facing the outer side of the vehicle after passing through the second through hole 301. When multiple third clamping portions 21 are provided, it is beneficial to adjust different third clamping portions 21 to be clamped and fixed to the second through hole 301.
[0050] Furthermore, the wheel arch side beam 300 is provided with an annular flange 302 that is turned up toward the outside of the vehicle, and the second through hole 301 is formed on the inner side of the annular flange 302, the end of the annular flange 302 abuts against the clamping surface 212, and the inner wall surface of the annular flange 302 abuts against the conical surface 211.
[0051] Combination Figure 3 As shown, the wheel arch side beam 300 is provided with an annular flange 302, which is turned up toward the outside of the vehicle (i.e., the side opposite to the Y-axis in the figure) to form a flange structure protruding toward the outside of the vehicle, and a second through hole 301 is formed on the inner side of the annular flange 302. The end of the annular flange 302 facing the outside of the vehicle can abut against the clamping surface 212 to form a clamping relationship, and the inner wall surface of the annular flange 302 abuts against the conical surface 211.
[0052] In this way, through the design of the annular flange 302, the end of the annular flange 302 is abutted against the clamping surface 212 to form a clamping relationship, so that the inner wall surface of the annular flange 302 is abutted against the conical surface 211, thereby increasing the contact area with the third clamping portion 21, playing a certain limiting role, and thereby improving the stability of the second pipe section 2.
[0053] Further, the position of the first through hole 201 is higher than the position of the second through hole 301 .
[0054] Combination Figure 1 , Figure 4 and Figure 5 As shown in the figure, the position of the first through hole 201 is higher than the position of the second through hole 301, and the specific height difference value can be designed according to needs. In this way, it is conducive to the flow of water from the first pipe section 1 to the second pipe section 2, ensuring the smooth flow of water and avoiding stagnation of water in the pipe.
[0055] Furthermore, the drainage pipe sheath is used to be installed on the left side and the right side of the vehicle respectively. A left mark 13 is provided on the outer surface of the first pipe section 1 installed on the left side of the vehicle, and a right mark is provided on the outer surface of the first pipe section 1 installed on the right side of the vehicle.
[0056] Generally speaking, the drain pipe sheath can be installed on one side of the vehicle or on both sides of the vehicle. In this embodiment, the drain pipe sheath is installed on both sides of the vehicle (i.e., on both sides of the positive and negative directions of the Y axis in the figure). Figure 6 and Figure 7 As shown, on the first pipe section 1 of the drainage pipe sheath located on the left side of the vehicle (i.e., the opposite side of the Y-axis in the figure), a left mark 13 is provided by scratching, sticking, etc., and correspondingly, on the first pipe section 1 of the drainage pipe sheath on the right side of the vehicle (i.e., the vehicle part not shown on the positive side of the Y-axis in the figure), a right mark is provided, and the left and right can be distinguished by patterns or texts. For example, in this embodiment, the left mark is L and the right mark is R.
[0057] In this way, the left mark 13 and the right mark are used to distinguish the drainage pipe sheaths on the left and right sides, which makes it easier for assemblers to distinguish and improves assembly efficiency.
[0058] Furthermore, a one-way arrow mark 14 is provided on the first clamping portion 11 and / or the second clamping portion 12 , and a straight line mark 202 is provided on the lower cross beam 200 of the windshield, and the one-way arrow mark is arranged toward the top direction of the vehicle and parallel to the straight line mark 202 .
[0059] Combination Figure 6 and Figure 7 As shown, a one-way arrow mark 14 is provided on the first clamping portion 11, and a straight line mark 202 is correspondingly provided on the lower cross beam 200 of the windshield. After assembly, the one-way arrow mark 14 faces the top direction of the vehicle (i.e., the positive direction of the Z axis in the figure), and the one-way arrow mark 14 and the straight line mark 202 are parallel to each other. It can be imagined that the solution of providing the one-way arrow mark 14 on the second clamping portion 12 and correspondingly providing the straight line mark 202 on the lower cross beam 200 of the windshield is also feasible, and the corresponding design can be selected according to the actual assembly direction.
[0060] In this way, the unidirectional arrow mark 14 and the straight line mark 202 can help assemblers identify the assembly direction of the drainage pipe sheath, thereby improving assembly efficiency.
[0061] Furthermore, one of the third clamping portions 21 is provided with a scaled mark, and when the third clamping portion 21 is clamped with the edge of the second through hole 301 facing the outer side of the vehicle, the scaled mark is aligned with the edge of the second through hole 301 facing the inner side of the vehicle (not shown in the diagram of this solution).
[0062] The engraved mark can be set in a bright and eye-catching color to indicate the assembly position of the second pipe section 2, so that the assembler can more accurately and quickly clamp the corresponding third clamping portion 21 on the second pipe section 2 to the second through hole 301, thereby improving the assembly efficiency.
[0063] The drain pipe sheath in the utility model has a first pipe section 1 that penetrates and is connected to a first through hole 201 of a lower cross beam 200 of a windshield, and a second pipe section 2 that penetrates and is connected to a second through hole 301 on a wheel arch side beam 300, thereby realizing connection and fixation of the drain pipe sheath through two mounting points, improving the connection stability between the drain pipe sheath and the vehicle body, avoiding leakage caused by the drain pipe 100 falling off and the like, and avoiding noise caused by the shaking of the drain pipe 100; and, since the outlet end of the second pipe section 2 of the drain pipe sheath guides the water flow to the external space outside the vehicle, rather than the scheme in which the outlet end is arranged toward the forward direction of the vehicle in a conventional structure, whistling noise caused by airflow pouring into the outlet end of the second pipe section 2 during driving is avoided; in addition, since the outlet end of the second pipe section 2 directly guides the water flow to the outside, rather than the scheme in which the water flow is guided to the wet area of the vehicle in a conventional structure (for example, guiding the water flow to the air chamber plate 400 and providing water holes on the air chamber plate 400), the risk of rust in the wet area of the vehicle is reduced.
[0064] The utility model also provides a vehicle, comprising the above-mentioned drainage pipe protective sheath.
[0065] In the vehicle of the utility model, the first pipe section 1 of the drain pipe sheath passes through and is connected to the first through hole 201 of the cross beam 200 under the windshield, and the second pipe section 2 passes through and is connected to the second through hole 301 on the wheel arch side beam 300, so that the connection and fixation of the drain pipe sheath is achieved through two installation points, thereby improving the connection stability between the drain pipe sheath and the vehicle body, avoiding water leakage caused by reasons such as the drain pipe 100 falling off, and avoiding noise caused by the shaking of the drain pipe 100; and, since the outlet end of the second pipe section 2 of the drain pipe sheath guides the water flow to the external space outside the vehicle, instead of the scheme in which the outlet end is arranged toward the forward direction of the vehicle in the traditional structure, the whistle noise caused by the airflow pouring into the outlet end of the second pipe section 2 during driving is avoided; in addition, since the outlet end of the second pipe section 2 directly guides the water flow to the outside, instead of the scheme in which the water flow is guided to the wet area of the vehicle in the traditional structure, the risk of rust in the wet area of the vehicle is reduced.
