Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a drainage structure of an electric tail wing base and an electric tail wing assembly. Background Art

[0002] In order to effectively reduce and overcome the influence of air resistance when the car is driving at high speed, a spoiler is installed at the rear of the car. The spoiler can make the air resistance form a downward pressure, try to offset the lift, effectively control the downward pressure of the airflow, and reduce the drag coefficient accordingly, thereby increasing the high-speed driving stability of the car. The electric spoiler can automatically adjust the position of the spoiler according to needs, but the electric spoiler is prone to not working properly when it encounters water. Therefore, a drainage structure is generally set at the base of the electric spoiler. Whether the drainage performance of the drainage structure is stable and reliable is particularly important to the entire spoiler system.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] like Figure 1 - Fig.12As shown, an electric tail wing base drainage structure of an embodiment of the present invention is used to be installed on the electric tail wing base 8 to drain the accumulated water in the electric tail wing base 8 to prevent water from accumulating in the electric tail wing base 8 and affecting the normal operation of the electric tail wing. The electric tail wing base drainage structure includes a base 1, a drainage cylinder 2 and a drainage pipe 4, wherein the base 1 is provided with a cavity that passes through from top to bottom; the drainage cylinder 2 is inserted in the cavity, the top of the drainage cylinder 2 is provided with a water inlet, and the bottom of the drainage cylinder 2 is open; the bottom of the drainage cylinder 2 is fixed to the cavity wall of the cavity, and the top of the drainage cylinder 2 is spaced from the cavity wall of the cavity so that a water collection tank 3 with a notch facing upward is formed between the cylinder wall of the drainage cylinder 2 and the cavity wall of the cavity; the drainage pipe 4 is connected to the bottom of the base 1, and the drainage pipe 4 is connected to the cavity and the drainage cylinder 2 in sequence.

[0038] The accumulated water in the electric tail base 8 first enters the water collection tank 3, and after gathering to a certain height in the water collection tank 3, the water inlet enters the drainage tube 2, and flows out through the drainage tube 2, the cavity, and the drainage pipe 4 in sequence. After the mud and sand and other debris enter the water collection tank 3 with the water flow, the mud and sand and other debris settle in the water collection tank 3, slowing down the speed of the water flow. After the water level in the water collection tank 3 rises, the water flow enters the drainage tube 2, thereby preventing mud and sand and other debris from entering the drainage tube 2 and blocking the drainage pipe 4, ensuring the stability of the drainage structure. The mud and sand and other debris in the water collection tank 3 can be cleaned regularly.

[0039] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the top of the drain tube 2 is open, and a baffle 21 is provided at the top opening. A notch 22 connected to the top opening is provided at the top of the wall of the drain tube 2. The gaps between the baffles 21 and the notch 22 together form the water inlet at the top of the drain tube 2. The baffle 21 can prevent larger foreign objects (such as large stones, leaves, etc.) from entering the drain tube 2. Even if the leaves cover the top opening, water can enter the drain tube 2 from the lateral notch 22. There can be multiple baffles 21, and the multiple baffles 21 are arranged at intervals or crosswise. Optionally, there are two baffles 21, and the two baffles 21 are arranged at the top opening in a cross-shaped manner. There can be multiple notches 22, and the multiple notches 22 are arranged at intervals along the circumference of the drain tube 2. The top position of the drain tube 2 can be slightly higher than the top position of the cavity, and the water in the sump 3 enters the drain tube 2 from the notch 22.

[0040] like Figure 6As shown, the drain cylinder 2 is in a cone shape that is small at the top and large at the bottom, and the central axis of the cone-shaped drain cylinder 2 is in line with the central axis of the cavity in the base 1. Setting the drain cylinder 2 in a cone shape not only facilitates the fixing of the bottom of the cylinder wall of the drain cylinder 2 with the cavity wall, but also forms a water collection tank 3 between the cylinder wall of the drain cylinder 2 and the cavity wall.

[0041] Example 1 - Fig.12 As shown, the base 1 includes an annular seat plate 11 and a tube body 12. The annular seat plate 11 is used to be installed on the electric tail wing base 8. One end of the tube body 12 is fixed to the inner edge of the annular seat plate 11, and the other end of the tube body 12 is connected to the drain pipe 4. The internal space of the tube body 12 forms a cavity, and the drain cylinder 2 is inserted in the tube body 12. The annular seat plate 11 is coaxially arranged with the tube body 12. The central axis of the tube body 12 is colinear with the central axis of the drain cylinder 2. The annular seat plate 11 can be used as a mounting seat for the tube body 12, and the annular seat plate 11 is connected to the electric tail wing base 8.

[0042] Further, optionally, as Figure 2 - Figure 6 As shown, the annular seat plate 11 is detachably sealed and connected to the lower surface of the electric tail wing base 8. For example, a positioning hole is provided on the electric tail wing base 8, the upper surface of the annular seat plate 11 is fitted on the lower surface of the electric tail wing base 8, the tube body 12 is coaxially arranged with the positioning hole, the inner wall of the tube body 12 is flush with the hole wall of the positioning hole, and the top of the drain tube 2 can be inserted into the positioning hole. Bolts 9 are welded on the electric tail wing base 8, the annular seat plate 11 is fixed to the electric tail wing base 8 by nuts, and a sealing ring 7 is clamped between the annular seat plate 11 and the electric tail wing base 8, so that the annular seat plate 11 and the electric tail wing base 8 are sealed and connected, which plays a waterproof role for the electric tail wing base 8.

[0043] Alternatively, if Figure 7 - Fig.12 As shown, the electric tail wing base drainage structure also includes a sleeve 5, one end of the sleeve 5 is provided with a flange 6, the flange 6 is annular, a rubber sleeve 61 is sleeved on the flange 6, the other end of the sleeve 5 is connected to the drainage pipe 4, the sleeve 5 is sleeved on the outer peripheral side of the tube body 12, and the sleeve 5 and the tube body 12 can be threadedly connected. The rubber sleeve 61 plays a waterproof role for the electric tail wing base 8.

[0044] A positioning hole is provided on the electric tail wing base 8, and the tube body 12 is coaxially inserted in the positioning hole of the electric tail wing base 8, and the tube body 12 passes through the electric tail wing base 8 downward, and the annular seat plate 11 is attached to the upper surface of the electric tail wing base 8 to facilitate the installation and positioning of the base 1, and the rubber sleeve 61 is attached to the lower surface of the electric tail wing base 8 to play a waterproof role for the electric tail wing base 8.

A small amount of accumulated water in the electric tail wing base 8 can enter the water collecting tank 3 from the water inlet grooves 111 to achieve the function of lateral low-level drainage and reduce the accumulated water in the electric tail wing base 8. The notch of the water inlet groove 111 faces downward, and the groove length direction of the water inlet groove 111 extends along the radial direction of the annular seat plate 11. The water inlet groove 111 penetrates the annular seat plate 11 along the radial direction of the annular seat plate 11 to connect the space in the electric tail wing base 8 with the internal space of the water collecting tank 3.

[0046] Alternatively, if Figure 8 - Fig.12 As shown, a hook 121 is provided at the bottom of the tube body 12, and a boss 51 is provided on the inner wall of the sleeve 5 for clamping the hook 121. When the sleeve 5 is installed, the hook 121 is clamped into the boss 51, indicating that the sleeve 5 is assembled in place. At this time, the rubber sleeve 61 is in contact with the electric tail base 8, and the sealing performance is good. The cooperation between the hook 121 and the boss 51 can not only prevent the sleeve 5 from slipping off the tube body 12, but also position the assembly of the sleeve 5 and the tube body 12, ensure the sealing performance between the rubber sleeve 61 and the electric tail base 8, and improve the waterproof performance of the electric tail base 8. A plurality of hooks 121 can be provided, and the plurality of hooks 121 are arranged at intervals along the circumference of the tube body 12.

The accumulated water in the electric tail base 8 can enter the water collection tank 3 from the lateral water inlet groove 111 or the surface of the annular seat plate 11, and the mud and sand and other debris settle in the water collection tank 3. The water overflows the water collection tank 3 and enters the drainage tube 2, and flows out through the tube body 12 and the drain pipe 4.

[0049] Alternatively, during installation, the annular seat plate 11 of the base 1 is clamped with the sealing ring 7 and fixed to the lower surface of the electric tail wing base 8 by bolts 9, and the drain cylinder 2 is coaxial with the positioning hole of the electric tail wing base 8; the drain pipe 4 is connected to the lower end of the tube body 12 of the base 1, and the accumulated water in the electric tail wing base 8 is discharged through the drain cylinder 2, the tube body 12, and the drain pipe 4.
