Abstract
Description
Technical Field
[0001] This application relates to the field of automotive technology, and in particular to a water guiding structure for use with a windshield and an automobile. Background Technology
[0002] During rain or car washes, water on the windshield flows downwards and is eventually drained through drainage structures on the engine compartment sheet metal. At higher speeds and while the wipers are working, significant amounts of water flow down the sides of the windshield and then along the lower sheet metal structure. To prevent water from seeping into the passenger compartment between the windshield and the body panel frame, a seal is typically installed between the windshield and the body panel frame.
[0003] like Figure 1 As shown, a conventional sealing structure is illustrated. The seal 3' is positioned inside the bottom frame 1' and side frame 2', with the windshield covering the seal 3', bottom frame 1', and side frame 2'. Water flowing from both sides of the windshield can enter between the windshield and the side frame 2', but due to the obstruction of the seal 3', the water flow is limited to the outer edge of the seal 3', such as... Figure 1 As indicated by the dashed arrow, when water flows to the lower corner of the windshield, some water can flow out through the gap between the side frame 2' and the bottom frame 1'. However, due to the surface tension of the liquid, some water will adhere to the outer edge of the seal 3' and continue to flow laterally along the seal 3'. This portion of water poses a risk of flowing into the air conditioning intake, potentially causing water ingress into the cockpit and severely impacting the normal operation of the air conditioning system, such as causing electrical malfunctions and reducing air conditioning efficiency.
[0004] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

[0032] The present application provides a water guide structure matched with a front windshield. The water guide structure matched with the front windshield can block and guide the water flow along the front windshield, especially the water flow along the two sides of the front windshield, so that the water flow is discharged as soon as possible, and the water flow is prevented from flowing to the air conditioner inlet.
[0033] Please refer to Figure 2 As shown, the water guide structure includes a bottom frame 1, a side frame 2 and a sealing rubber strip 3. The front windshield is arranged obliquely in front of the automobile, and the front windshield is generally rectangular, having left and right side edges, a top edge and a bottom edge. The bottom frame 1 is arranged corresponding to the bottom edge of the front windshield. At least a part of the bottom frame 1 is located below the bottom edge of the front windshield, for supporting the bottom edge of the front windshield. The side frame 2 is arranged corresponding to the side edge of the front windshield. At least a part of the side frame 2 is located below the left and right side edges of the front windshield, for supporting the left and right side edges of the front windshield.
[0034] The sealing strip 3 is arranged along the edge of the front windshield, and the sealing strip 3 comprises a side edge strip 31 extending along the side edge frame 2 and a bottom edge strip 32 extending along the bottom edge frame 1. The sealing strip 3 further comprises a blocking part 33 arranged between the side edge strip 31 and the bottom edge strip 32, and the blocking part 33 can prevent the water flow flowing along the side edge strip 31 from flowing to the bottom edge strip 32.
[0035] The water guide structure matched with the front windshield provided in the application comprises a sealing strip 3, the sealing strip 3 comprises a side edge strip 31, a bottom edge strip 32 and a blocking part 33 arranged between the side edge strip 31 and the bottom edge strip 32, and the blocking part 33 can prevent the water flow flowing along the side edge strip 31 from flowing to the bottom edge strip 32, so that the water flow flowing along the side edge strip 31 can be discharged in time, the lateral flow of the side edge water flow is prevented, the water flow flowing along the bottom edge strip 32 to the air conditioner air inlet is prevented, and the water inflow in the cab and the air conditioner system failure are avoided.
[0036] Please continue to refer to Figure 2 As shown in the figure, the bottom edge frame 1 is matched with the bottom edge of the front windshield, and the extension direction of the edge of the bottom edge frame 1 is transverse, which is basically the same as the extension direction of the bottom edge of the front windshield. In this embodiment, the bottom edge frame 1 is a lower cross beam, which is a sheet metal part. It should be noted that the bottom edge frame 1 can be an integral part or composed of multiple parts.
[0037] The side edge frame 2 is matched with the side edge of the front windshield, and the extension direction of the edge of the side edge frame 2 is longitudinal, which is basically the same as the extension direction of the side edge of the front windshield. In this embodiment, the side edge frame 2 is a vehicle body sheet metal at the A-pillar of the vehicle. The side edge frame 2 is located at the left and right sides of the front windshield, and the side edge frame 2 can be an integral part or composed of multiple parts. In some embodiments, the side edge frame 2 and the bottom edge frame 1 can also be connected as a whole.
[0038] Please continue to refer to Figure 2 As shown in the figure, a drainage port 101 is formed between the side edge frame 2 and the bottom edge frame 1. In this embodiment, the lower end of the side edge frame 2 has a spacing with the end of the bottom edge frame 1 to form the drainage port 101. The water flow flowing downward from the left and right sides of the front windshield can be discharged through the drainage port 101 and separated from the front windshield; further, a flow guide structure corresponding to the drainage port 101 is arranged on the engine compartment sheet metal, which can guide the water flow to finally be discharged from the vehicle to the ground.
[0039] The side sealing strip 31 of the sealing strip 3 extends along the inner side of the edge of the side frame 2, that is, the extending direction of the side sealing strip 31 is the longitudinal direction which is substantially the same as the extending direction of the edge of the side frame 2. The bottom sealing strip 32 of the sealing strip 3 extends along the inner side of the edge of the bottom frame 1, that is, the extending direction of the bottom sealing strip 32 is the transverse direction which is substantially the same as the extending direction of the edge of the bottom frame 1. The sealing strip 3 comprises a transition section between the side sealing strip 31 and the bottom sealing strip 32. The transition section connects the side sealing strip 31 and the bottom sealing strip 32 into one, forming a continuous and encapsulated sealing strip. The barrier portion 33 is protrudingly arranged from the end of the transition section close to the bottom sealing strip 32 towards the bottom frame 1. In this embodiment, the barrier portion 33 protrudes towards the bottom frame 1 and forms a sealed contact with the bottom frame 1. The barrier portion 33 is arranged at both ends close to the bottom frame 1, and the bottom frame 1 is combined with the air conditioner air inlet at the middle part. The barrier portion 33 is arranged in this way to prevent the water flow along the side sealing strip 31 from flowing along the outer side of the transition section to the bottom sealing strip 32, and to avoid the water flow continuing to flow transversely along the bottom sealing strip 32 and possibly flowing to the air conditioner air inlet, which will adversely affect the air conditioning system. In this embodiment, the transition section, the barrier portion 33, and the side frame 2 and the bottom frame 1 form a water blocking cavity 301, and the drain port 101 communicates with the water blocking cavity 301. Compared with the gap between the side sealing strip 31 and the side frame 2, and the gap between the bottom sealing strip 32 and the bottom frame 1, the space of the water blocking cavity 301 is increased, and when the water flow flows into the water blocking cavity 301, the flow rate and pressure will decrease. Therefore, the arrangement of the water blocking cavity 301 can play a role in water storage and buffering when the water flow is too fast and the water flow is too large, so as to avoid the impact of the splashing of the too fast and too large water flow on the sealing strip 3, which will cause damage to the sealing strip 3 over a long period of time.
[0040] In this embodiment, the transition section is arranged in a straight manner, so that the side sealing strip 31 and the bottom sealing strip 32 are connected in a straight line. In other words, compared with the traditional circular arc transition connection, the embodiment adopts a substantially straight line connection. By arranging the transition section in a straight manner, on the one hand, the volume of the water blocking cavity 301 can be increased, and the water storage and buffering capacity can be improved; on the other hand, the transition between the side sealing strip 31 and the bottom sealing strip 32 is not smooth, and there are obvious edges and corners, and the angle at the transition changes suddenly, so as to facilitate the water flow flowing along the side sealing strip 31 to directly flow to the drain port 101 and thus facilitate the discharge of the water flow and reduce the impact of the water flow on the sealing strip 3.
[0041] In the embodiment, the sealing strip 3 is formed by an adhesive between the lower surface of the front windshield and the upper surfaces of the side frame 2 and the bottom frame 1. That is, the sealing strip 3 has both adhesive and sealing functions. In an embodiment, the sealing strip 3 is formed by an adhesive extruded by an adhesive dispenser in a strip shape, the adhesive is attached to the upper surfaces of the side frame 2 and the bottom frame 1, and the front windshield is extruded above the adhesive, and the sealing strip 3 is formed after the adhesive is dried and cured. In the embodiment, when the adhesive is dispensed, the transition section and the blocking section 33 are continuously formed when the side strip 31 is formed, and then the nozzle of the adhesive dispenser is lifted and the bottom strip 32 is formed by continuously dispensing the adhesive from the part coinciding with the transition section. In other embodiments, the dispensing steps are not limited to the above; in other embodiments, the sealing strip 3 can also be made in other ways.
[0042] Referring to Figure 3 In some embodiments, the bottom frame 1 is provided with a water guide groove 11 communicating with the water blocking cavity 301, as shown. The bottom frame 1 includes a sheet metal part, and the water guide groove 11 is a groove punched on the sheet metal part. By providing the water guide groove 11, the water flow blocked by the blocking section 33 can be quickly discharged, and the water flow direction is shown by the dashed arrow in the figure. Figure 3 The lower part of the water guide groove 11 can be further provided with holes, grooves, water receiving plates, etc. to discharge the water flow away from the air conditioner air inlet.
[0043] The application also provides an automobile comprising a front windshield and a water guide structure cooperating with the front windshield according to any one of the above embodiments. The automobile provided by the application adopts the above water guide structure, which can prevent liquid from entering the air conditioning system through the air conditioner air inlet to cause damage to the air conditioning system, and prevent liquid from being blown by the air conditioning system into the cab.
[0044] From the above description of the specific embodiments, it can be seen that the water guide structure cooperating with the front windshield provided by the application comprises a sealing strip 3, the sealing strip 3 comprises a side strip 31, a bottom strip 32, and a blocking section 33 arranged between the side strip 31 and the bottom strip 32, the blocking section 33 can prevent the water flow flowing along the side strip 31 from flowing to the bottom strip 32, so that the water flow flowing along the side strip 31 can be discharged in time, and the water flow flowing along the bottom strip 32 to the air conditioner air inlet is prevented.
[0045] The technical features of the above embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as the scope of the description.
[0046] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
