Description

Technical Field

[0001] The utility model relates to the technical field of automobile windshield drainage, in particular to a front windshield drainage structure. Background Art

[0002] The front windshield drainage system is mainly composed of rain gathering plates, drainage holes and gutter decorative parts. When rain falls on the front windshield, it will flow along the glass surface to the rain gathering plates. The rain gathering plates will guide the rainwater or car wash water into the gutter. Finally, the rainwater and car wash water will be discharged out of the car through the gutter.

[0003] The Chinese invention patent with the authorization announcement number CN114954677B discloses a vehicle front windshield drainage structure and a vehicle, wherein the vehicle front windshield drainage structure includes a front panel, a ventilation cover and a mounting plate, a rubber strip is provided between the front panel and the ventilation cover, a plurality of ventilation holes are provided on the ventilation cover, a drainage hole is provided at the bottom of the water flow channel below the ventilation hole, a drainage groove is provided on the front panel below the ventilation cover, the drainage groove extends in the vehicle width direction, and a drainage port is provided at at least one end of the extension direction of the drainage groove, and a drainage groove is provided on the front panel at the ventilation cover. The mounting plate below is welded with a mounting bracket for connecting the ventilation cover, and the mounting bracket is wavy along the width direction of the vehicle, with a concave part and a convex part. Through the coordinated arrangement of the vents, water troughs and drainage holes, a first water flow channel can be formed between the vents, water troughs and drainage holes to guide rainwater or car wash water flowing in from the vents to the outside of the vehicle. Through the coordinated arrangement of the drainage troughs and drainage outlets, a second water flow channel can also be formed between the gap at the rubber strip, the drainage troughs and the drainage outlets to discharge the intruding water to the outside of the vehicle.

[0004] However, in the existing technology, since rainwater is discharged from the side of the vehicle body, there are many inconveniences in the application of new energy vehicles. New energy vehicles need to set charging ports on the fenders on both sides of the front wheels of the vehicle body. At this time, since the drainage grooves drain water to both sides, the drainage ports need to be avoided when designing the position of the charging ports. Therefore, charging ports and drainage ports are respectively set on both sides of the front wheels of the vehicle body, which occupies more area of ​​the vehicle body. Therefore, the following improvements are proposed to address this problem. Utility Model Content

[0005] The utility model is intended to provide a front windshield drainage structure to enable the drainage groove under the front windshield to discharge to the middle bottom end, and be applied in the new energy vehicle industry, without conflicting with the charging port positions on both sides of the vehicle body, thereby reducing the area occupied by the vehicle body.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: it includes a drainage trough installed on the vehicle body, a drainage outlet is opened at the bottom of the drainage trough along the transverse midpoint of the car, both sides of the drainage trough are inclined along the transverse direction of the car and between the drainage outlet, both ends of the drainage trough are higher than the drainage outlet, and a drainage pipe is connected to the drainage outlet below the drainage trough.

[0007] By adopting the above-mentioned technical features, by setting the two ends of the drainage trough to be inclined, and the two ends of the drainage trough are higher than the drainage outlet, after the rainwater flows into the drainage trough through the front windshield, the rainwater flows from both sides of the drainage trough to the middle, and finally flows into the drainage pipe through the drainage outlet. The drainage pipe finally discharges the rainwater out of the car without adopting the traditional method of draining water to both sides. Therefore, both sides of the car body can be utilized, and charging ports can be set on the side wings of the car body. The charging ports do not interfere with the drainage outlet, and other designs can be made on both sides of the rear wing of the car body; at the same time, the drainage trough drains water from the middle, and only a drainage system needs to be set up in the car body to drain the water in the drainage pipe. Compared with the existing technology, drainage on both sides of the drainage trough requires drainage systems on both sides of the car body, which saves costs and can achieve the effect of reducing the area occupied by the car body and saving costs.

[0008] The beneficial effect of this solution is that, compared with the existing technology, only a drain pipe needs to be connected in the middle of the drain trough to achieve the purpose of draining rainwater in the drain trough. In the previous design, the drain trough drains water to both sides, and it is necessary to add a water flow trough to the body structure, which has a relatively complex structure. In particular, the addition of a water flow trough to the body increases the mold development cost of the whole vehicle, the cost of each unit, and the weight of the whole vehicle.

[0009] The utility model is further configured as follows: a water collecting trough is provided at the drainage outlet of the drainage trough, the water collecting trough is inclined along the lateral sides of the car and between the drainage trough bottom plate, and the drainage outlet is opened at the bottom end of the water collecting trough.

[0010] By adopting the above technical features and setting up a water collection trough, rainwater flows to the water collection trough through both ends of the drainage trough. When the rain is heavy, the rainwater quickly stays in the water collection trough, which can increase the water pressure at the drain outlet, improve the rainwater filtration speed, and achieve the purpose of efficient and rapid drainage.

[0011] The utility model is further configured as follows: a sealing ring is connected to the top of the drain pipe, the sealing ring is located between the drain pipe and the drainage trough to seal and fix the drain pipe, a clamp is provided at the top of the drain pipe, the sealing ring has a clamping groove corresponding to the clamp, and a pull ring is fixedly provided at the top of the drain pipe, the pull ring is used to pull the drain pipe upward from the drain outlet to the inner cavity of the drainage trough.

[0012] By adopting the above technical features, a sealing ring is set, and the sealing ring is fixed to the top of the drain pipe through the clamp of the drain pipe. By setting a pull ring, the pull ring can be lifted during installation to pull the drain pipe from the drain outlet at the bottom end of the drain trough to the inner cavity of the drain trough. The sealing ring is located between the drain pipe and the drain trough, so that the drain pipe and the drain outlet have an interference fit, which can achieve the purpose of quickly installing the drain pipe without affecting drainage.

[0013] The utility model is further configured as follows: a pressing piece is provided at the top end of the drain pipe, a plurality of pressing pieces are symmetrically arranged on the top end face of the drain pipe, the pressing piece is provided with an inclined surface inclined upward along the axis of the drain pipe and a bottom surface perpendicular to the drain pipe, a pressing gap is provided between the bottom surface of the pressing piece and the end face of the drain pipe for the sealing ring to be embedded, and the bottom surface of the pressing piece is used to press the sealing ring against the surface of the water collection tank.

[0014] By adopting the above technical features, a pressing piece is set, and the pressing piece is circumferentially set at the top of the drain pipe. At the top of the drain pipe, when the drain pipe is installed at the bottom of the drain trough, the sealing ring is placed between the drain pipe and the drain trough. The circumferentially set pressing piece evenly presses the sealing ring on the surface of the drain trough through the bottom surface of the pressing piece, thereby achieving the purpose of fixing the sealing ring.

[0015] The present invention is further configured as follows: a clamping piece is arranged at the top of the drainage groove at the pressing gap, and the groove and the clamping piece are both configured as rectangles with the same shape and size.

[0016] By adopting the above technical solution, the sealing ring is placed in the pressing gap and between the drain pipe and the drain groove during installation. At this time, the position between the sealing ring and the drain pipe is fixed by the action of the clamp and the clamping groove, preventing the sealing ring from being dislocated during the installation of the drain pipe, thereby achieving the purpose of fixing the sealing ring.

[0017] The utility model is further configured as follows: fixing frames are installed at positions on both sides of the vehicle body corresponding to the drainage grooves, and both ends of the drainage grooves are welded to the fixing frames.

[0018] By adopting the above technical features, a fixing bracket is set up, the fixing bracket is installed on the vehicle body, the two ends of the drainage groove are welded to the fixing bracket, and then the appearance is improved by painting or gluing, ensuring that when rainwater flows into the drainage groove from the front windshield, it will not leak out from both sides of the drainage groove, and the purpose of sealing between the vehicle body and the two ends of the drainage groove can be achieved.

[0019] The utility model is further configured as follows: the fixing frame is provided with a threaded hole, and the fixing frame is threadedly connected to the vehicle body through the threaded hole.

[0020] The present invention is further configured as follows: a charging port for installing a charging column is opened on the side of the vehicle body near the end of the drainage groove.

[0021] By adopting the above technical features, there is no need for drainage grooves on the fenders on both sides of the front wheels of the vehicle body. Ultimately, the charging port is set on the fenders on both sides of the front wheels of the vehicle body, which can achieve the purpose of reducing the area occupied by the vehicle body.
