In general, the front windshield lower beam 1, the air chamber plate 3, and the a-pillar inner panel 2 described above surround to form the ventilation chamber 300, and the front windshield lower beam 1 is provided with a water passage for introducing water on the front windshield into the ventilation chamber 300. Wherein, a buffer space is reserved between the waterway and the connection part of the air chamber plate 3 and the A-pillar inner plate 2, so that the water flow entering the ventilation chamber 300 from the waterway avoids the connection part.

Specifically, in the present embodiment, the a-pillar inner panel 2 includes a main body portion 20, and a lap portion 21 attached to the top of the main body portion 20; wherein, the lapping part 21 is bent towards one side of the inner part of the vehicle and lapped on the end part of the lower beam 1 of the front windshield; and the air chamber plate 3 is attached to the main body portion 20. The A-pillar inner plate 2 comprises a main body part 20 and a lap joint part 21 which are respectively connected and matched with the A-pillar inner plate 2 and the front windshield lower beam 1, so that connection and assembly among the A-pillar inner plate, the A-pillar inner plate and the front windshield lower beam are facilitated, and the ventilation chamber 300 is well enclosed.

When the actual vehicle body is constructed, a side wall reinforcing plate 4 is further arranged outside the A-pillar inner plate 2, an A pillar 5 is connected above the side wall reinforcing plate 4, and the A pillar 5, a B pillar 6 and a threshold beam 7 form a frame of the front door.

As shown in fig. 3 in combination with fig. 4, a protrusion 22 is formed at the joint of the lap portion 21 and the main body portion 20 on the inner side of the a-pillar inner panel 2, i.e., the side facing the air chamber panel 3; the projection 22 corresponds to the spigot 30 at the end of the air chamber plate 3. The raised bulges 22 are arranged, so that the problem that the hole 200 between the A-pillar inner plate 2 and the spigot 30 of the air chamber plate 3 is too large can be effectively solved, and the size t of the hole 200 formed between the spigot 30 and the bulges 22 is below 2mm, so that the gluing and sealing can be conveniently realized. Moreover, as shown in fig. 2, the wiper blade holder 8 is located in front of the hole 200, which may hinder the gluing operation; therefore, the provision of the projection 22 ensures that the gap t at the hole 200 is less than 2mm, which is more helpful to ensure the quality of the final glue seal.

In addition, the end of the lower front windshield cross member 1 is provided with a sunken section 11 sunken relative to the main body of the lower front windshield cross member 1, so that a step 12 is formed between the main body and the sunken section 11, and the lap portion 21 of the a-pillar inner panel 2 is lapped on the sunken section 11. The end of the front windshield lower beam 1 is provided with a sunken section 11 for being in lap joint with the lap joint part 21, so that the front windshield lower beam 1 is conveniently positioned and connected with the A column inner plate 2, a water path can be formed between the lap joint part 21 and the step 12, and water on the front windshield can be conveniently drained into the ventilation chamber 300.

Meanwhile, a water guide groove 10 is formed in one side of the bottom of the lower cross beam 1 of the front windshield, and the water guide groove 10 extends to the sinking section 11. Thus, the waterway includes a first waterway 91 between the overlapping portion 21 and the step 12 and a second waterway 92 on the gutter 10 of the sinking section 11. The water flow from the front windshield flows into the second water passage 92 through the water guide groove 10 and the first water passage 91, and then enters the ventilation chamber 300. By constructing the water guide groove 10 extending to the sinking section 11 on the bottom side of the lower beam 1 of the front windshield, water on the front windshield can be conveniently guided into the second waterway 92 at the sinking section 11, so as to enter the ventilation chamber 300 from the end of the ventilation chamber 300, and the arrangement of the drainage channel 93 and the drainage port 94 in the ventilation chamber 300 can be facilitated.

As shown in fig. 4, the size of the buffer space between the second waterway 92 and the orifice 200, i.e., the size D of the buffer space in the vehicle width direction, is preferably set to be between 15 and 20 mm; for example, it may be 15mm, 16mm, 18mm, 19mm, 20mm, etc. Thus, the impact force of the water flow can be effectively relieved, and the water flow entering from the second water channel 92 can fall due to gravity before impacting the connecting part of the hole 200 and the like.

In the above arrangement, the main body 20 is provided with a drain port 94 for discharging water in the ventilation chamber 300. As shown in fig. 3, the water entering the ventilation chamber 300 is discharged from the discharge port 94 through the discharge passage 93; the main body 20 is provided with a drain port 94 for facilitating the nearby drainage of the water in the ventilation chamber 300 to the outside of the vehicle.

In the embodiment, the connection form of the front windshield lower cross beam 1, the a-pillar inner panel 2 and the air chamber panel 3 can be flexibly selected, such as riveting, screwing or welding. Preferably, the end of the air chamber plate 3 is provided with a first flanging 31, and the air chamber plate 3 is connected with the A-pillar inner plate 2 through the first flanging 31 in a welding manner; and the joint of the air chamber plate 3 and the a-pillar inner plate 2 is filled with a sealant. The first flanging 31 arranged on the air chamber plate 3 is connected with the A-column inner plate 2 in a spot welding or full welding manner, and under the condition that a hole 200 or a gap exists at the connecting part of the A-column inner plate 2 and the air chamber plate 3, the sealing process by gluing is adopted, so that the ventilation chamber 300 and the cockpit can be well sealed and isolated.

Meanwhile, the top of the air chamber plate 3 is provided with a second flanging, and the air chamber plate 3 and the front windshield lower cross beam 1 are preferably connected by spot welding through the second flanging. The air chamber plate 3 and the front windshield lower cross beam 1 are connected through welding by adopting the second flanging, so that the connection strength and the assembly convenience between the air chamber plate 3 and the front windshield lower cross beam 1 can be guaranteed.

In summary, in the front windshield lower beam drainage structure of the embodiment, in the connection structure of the front windshield lower beam 1, the a-pillar inner plate 2 and the air chamber plate 3, the water channel formed on the front windshield lower beam 1 is used to introduce the water flow on the front windshield into the ventilation chamber 300, and a buffer space is reserved between the position where the water channel enters the ventilation chamber 300 and the connection part of the air chamber plate 3 and the a-pillar inner plate 2, so that the water flow entering from the water channel falls under gravity in the buffer space to avoid impact on the connection part of the air chamber plate 3 and the a-pillar inner plate 2, and thus the problem that the glue seal at the connection part of the a-pillar inner plate 2 and the air chamber plate 3 is easy to fail due to impact of water, and water leakage occurs at the connection part can be improved.

Example two

The embodiment relates to a vehicle, and the vehicle is provided with the front windshield lower cross beam drainage structure provided by the first embodiment.

In the existing design, under the condition that the arrangement of the periphery of the lower beam 1 of the front windshield allows, the flanging of the air chamber plate 3 faces downwards and is in lap joint with the lower section of the A-column inner plate 2 through a flanging fillet, the gap formed after lap joint is smaller than 2mm, and then the gap is sealed by glue, so that the sealing and waterproof effects are achieved. When the gluing operation space is excellent, the sealing of the hole gap can be well carried out, and the water inflow of the cockpit is avoided.

However, some vehicle types are affected by the arrangement of a power assembly or a suspension, the air chamber plate 3 can only be turned upwards, and cannot form fillet lap joint with the lap joint of the lower section inner plate of the A column, but the spigot 30 at one end of the air chamber plate 3, which is connected with the inner plate 2 of the A column, is matched with the fillet transition part of the inner plate 2 of the A column, and the hole 200 formed at the matching part is larger than 3mm, and the hole 200 is larger, so that the gluing sealing is not facilitated. The influence of the wiper blade carrier 8 shown in the figure makes the gluing operation more difficult. Leading to the problem that the gluing quality of the holes 200 cannot be guaranteed. In the case that the glue quality at the hole 200 cannot be guaranteed, if the hole is impacted by the entering water flow, the sealing performance of the glue seal can be easily failed.

The risk of water immersion of the cockpit can be avoided by gluing and sealing the hole 200 between the A-column inner plate 2 and the air chamber plate 3, and the distance D of the buffer space between the second water channel 92 and the hole 200 reaches 15-20mm through the position offset arrangement of the water channel on the lower cross beam 1 of the front windshield, so that water flow is guided to the ventilation chamber 300 at the second water channel 92 and then is discharged out of the vehicle from the water discharge port 94. Most of water flow can fall down and be discharged, and cannot impact the hole 200, so that repeated impact of the water flow on the sealant can be avoided, and the possibility that the water flow enters the cockpit from the hole 200 can be reduced.

The reasonable setting of buffering space size can ensure the sufficient mode and the rigidity performance of preceding wind window department, has also improved the gluey seal of the junction of A post inner panel 2 and air chamber board 3 and has become invalid because of being hit by the water easily, and then the problem that takes place to leak at the junction. Therefore, the risk of cabin flooding is reduced while the overall rigidity performance of the front windshield lower cross beam 1, the A-column inner plate 2 and the air chamber plate 3 is guaranteed.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
