[0031] Furthermore, the water flow channel assembly 2 includes a water flow channel 21 and an air chamber plate 22 . The air chamber plate 22 is connected to the water flow channel 21 and extends toward the rear.

[0032] Combination Figure 1 and Figure 2 As shown, the water flow channel 21 is usually in the shape of a groove, the front end of the air chamber plate 22 (i.e., the end in the positive direction of the X-axis in the figure) is fixedly connected to the rear end of the water flow channel 21 (i.e., the end in the opposite direction of the X-axis in the figure), and the rear end of the air chamber plate 22 (i.e., the end in the opposite direction of the X-axis in the figure) extends toward the rear (i.e., extends in the opposite direction of the X-axis in the figure. It can be understood that the air chamber plate 22 is not limited to being completely parallel to the X-axis. The air chamber plate 22 can have a certain angle with the X-axis. At the same time, it is not limited to being a flat plate. Its specific shape can be specifically designed according to needs), and the lower end of the second plate 12 (i.e., the end in the opposite direction of the Z-axis in the figure) is fixedly connected to the upper plate surface of the air chamber plate 22 (i.e., the plate surface facing the positive direction of the Z-axis).

[0033] In this way, the lower end of the second plate 12 is connected to the upper plate surface of the air chamber plate 22, and the air chamber plate 22 provides upward support for the lower cross beam 1 of the windshield, and the lower cross beam 1 of the windshield separates the cockpit and the engine compartment. The front end of the air chamber plate 22 is located on the side of the engine compartment, providing a mounting point for the water flow channel 21, and the rear end of the air chamber plate 22 is located on the side of the cockpit, providing a mounting point for the electrical system, interior and exterior parts (such as instrument panels, air conditioning, head-up display systems, wiring harnesses, etc.), etc., to meet the various multi-functional requirements of the market for vehicles today. In addition, the bottom of the air chamber plate 22 can provide mounting points for structures such as the front panel and the shock absorber tower.

[0034] Furthermore, the rear end of the water flow trough 21 is detachably connected to the front end of the air chamber plate 22 , and a first sealing member 01 is provided at the connection between the rear end of the water flow trough 21 and the front end of the air chamber plate 22 .

[0035] Combination Figure 1 and Figure 2 As shown, the rear end of the water trough 21, that is, the side wall of the water trough 21 close to the opposite side of the X-axis, and the front end of the air chamber plate 22 are provided with a flange structure, and the flange structure and the side wall of the water trough 21 are detachably connected to each other by bolts. Those skilled in the art can also adopt other detachable designs, such as snap-on, pin shaft, etc., and then combine Figure 3 As shown, a first sealing member 01 (such as a sealing strip, etc.) is provided at the connection between the rear end of the water flow channel 21 and the front end of the air chamber plate 22 .

[0036] In this way, the water trough 21 and the air chamber plate 22 are detachably connected, which facilitates the installation, disassembly and replacement of the water trough 21. At the same time, the first seal 01 ensures the sealing performance of the connection between the water trough 21 and the air chamber plate 22, thereby preventing water from flowing into the engine compartment and preventing exhaust gas and noise from being transmitted to the cockpit, thereby improving NVH (Noise, Vibration, Harshness) performance and driving experience.

[0037] In addition, combined Figure 3 As shown, the third sealing member 03 is provided on the left and right sides of the water flow groove 21 to seal and connect with the inner plate of the A-pillar. In this way, it can ensure that water is smoothly discharged from the left and right sides of the water flow groove 21 to the outside of the vehicle, and prevent water from flowing into the engine compartment through the gap between the inner plate of the A-pillar and the water flow groove 21.

[0038] Furthermore, the water flow trough 21 includes a plurality of trough sections 211 , the rear end of the trough section 211 is detachably connected to the front end of the air chamber plate 22 , and adjacent trough sections 211 are detachably connected and are provided with a second sealing member 02 .

[0039] Combination Figures 1 to 3 As shown, the length of each slot segment 211 along the Y-axis direction may be equal or unequal. In the present embodiment, there are two slot segments 211, which are detachably connected to each other by bolts to form a complete water flow slot 21. A second sealing member 02 (such as a sealing strip, etc.) is provided between the two slot segments 211. The second sealing member 02 is arranged around the bolts, thereby sealing the connection between the slot segments 211 and the bolt holes.

[0040] In this way, through the design of multiple groove sections 211, each part of the water flow groove 21 can be installed, disassembled and replaced separately, which provides convenience for the installation, disassembly and replacement of the water flow groove 21. At the same time, the second seal 02 is used to ensure the sealing performance of the connection between adjacent groove sections 211 to prevent water from flowing into the engine compartment.

[0041] Furthermore, the reinforcement member 4 includes a first reinforcement member 41 , the upper end of the first reinforcement member 41 is connected to the support member 3 , and the lower end of the first reinforcement member 41 is connected to the upper plate surface of the air chamber plate 22 .

[0042] Combination Figure 1 and Figure 2 As shown, the upper end of the first reinforcement 41 (i.e., the end along the positive direction of the Z axis) is fixedly connected to the support member 3. Since the lower end of the second plate 12 is connected to the upper plate surface of the air chamber plate 22, a part of the structure of the air chamber plate 22 is located on the front side of the second plate 12 (i.e., the side along the positive direction of the X axis), and the other part of the structure is located on the rear side of the second plate 12 (i.e., the side along the opposite direction of the X axis). The lower end of the first reinforcement 41 (i.e., the end along the opposite direction of the Z axis) is fixedly connected to the upper plate surface of the front part of the air chamber plate 22.

[0043] In this way, the first reinforcement member 41 is connected between the air chamber plate 22 and the support member 3, thereby playing a reinforcement role, so that the stiffness, strength and mode of the structure near the first reinforcement member 41 are improved; the number and position of the first reinforcement members 41 should be designed according to their reinforcement effect and the impact on pedestrian protection performance, and are not limited here.

[0044] Furthermore, the reinforcement member 4 further includes a second reinforcement member 42 , the lower end of the second reinforcement member 42 is connected to the water flow channel 21 , and the upper end of the second reinforcement member 42 is connected to the front end of the first reinforcement member 41 .

[0045] Combination Figure 1 and Figure 2 As shown, the second reinforcement member 42 is a long rod structure with a groove-shaped cross section. The lower end of the second reinforcement member 42 (i.e., the end in the opposite direction of the Z axis) is fixedly connected to the water flow channel 21. The front end of the first reinforcement member 41 (i.e., the end in the positive direction of the X axis) is provided with a flange structure to be fixedly connected to the upper end of the second reinforcement member 42 (i.e., the end in the positive direction of the Z axis). Optionally, the upper end of the second reinforcement member 42 is detachably connected to the front end of the first reinforcement member 41. For example Figure 1 and Figure 2 The two are detachably connected by bolts, thereby facilitating the assembly and disassembly of the water trough 21.

[0046] In this way, the second reinforcement 42 is connected between the first reinforcement 41 and the water flow channel 21, so that a mutual support relationship is formed between the support member 3 and the water flow channel 21 and the air chamber plate 22, thereby improving the torsional stiffness, strength and mode of the upper structure of the front wall of the vehicle body.

[0047] Preferably, a convex portion 212 is provided at the bottom of the water flow trough 21, and the lower end of the second reinforcement member 42 is connected to the convex portion 212. The bottom of the water flow trough 21 gradually deepens from the convex portion 212 to the left and right sides.

[0048] Combination Figure 2 and Figure 3 As shown, the bottom of the water trough 21 is designed to be high in the middle and low on the left and right sides, that is, a protrusion 212 is provided near the middle of the bottom of the water trough 21, so that the protrusion 212 forms the highest point, and the bottom of the trough gradually deepens from the protrusion 212 to the left and right sides (i.e., the positive and negative sides of the Y-axis), and a stepped structure or a slope structure can be used so that water will automatically flow to the left and right sides under the influence of gravity and thus be discharged out of the vehicle.

[0049] Optionally, combined Figure 2 As shown, the lower end of the second reinforcement member 42 (i.e., the end opposite to the Z axis) is connected to the protrusion 212. In this way, it is beneficial to improve the reinforcement effect of the second reinforcement member 42, better improve the torsional rigidity, strength and mode of the upper structure of the front wall of the vehicle body, and at the same time avoid affecting the flow of water, ensuring that the water flows smoothly to both sides in the water flow channel 21 and is discharged outside the vehicle.

[0050] Preferably, the water flow trough 21 is provided with a wire harness through hole 213 to cooperate with the wire harness in a sealed connection.

[0051] Combination Figure 3 As shown, in this embodiment, the water flow trough 21 is composed of multiple trough sections 211 that are detachably connected. A wiring harness through-hole 213 is opened on one of the trough sections 211, and the wiring harness can pass through the wiring harness through-hole 213. A sealing glue plug is usually provided on the periphery of the wiring harness, thereby sealingly connecting with the wiring harness through-hole 213 to prevent water from flowing into the engine compartment through the wiring harness through-hole 213.

[0052] Preferably, the first plate 11, the second plate 12 and the support member 3 form a cavity.

[0053] Combination Figure 1 and Figure 2As shown, the first plate 11 and the second plate 12 are arranged at a certain angle, and the support member 3 is a plate structure. The lengths of the support member 3, the first plate 11 and the second plate 12 in the Y-axis direction are basically the same. In this way, after the support member 3 is connected between the first plate 11 and the second plate 12, a cavity similar to a triangle is formed, which can play a reinforcing role for each position of the upper structure of the front wall of the vehicle body on the Y-axis (i.e., horizontally, i.e., the width direction of the vehicle). On the one hand, the upper structure of the front wall of the vehicle body of the utility model realizes the supporting and reinforcing effect through the support member 3 and the reinforcement member 4, which can improve the overall torsional stiffness, strength and mode. On the other hand, the plate thickness of the first plate 11, the second plate 12 and the support member 3 can be in the range of, for example, 0.6 to 0.7 mm. Compared with the traditional upper structure of the front wall of the vehicle body, thinner plate materials are used, thereby weakening the local strength and improving the pedestrian protection performance.

[0054] Furthermore, it also includes a wiper mounting bracket 5 , the lower end of the wiper mounting bracket 5 is connected to the upper plate surface of the air chamber plate 22 , and the upper end of the wiper mounting bracket 5 is connected to the support member 3 .
