Description

Technical Field

[0001] This utility model belongs to the field of automotive water spraying technology, specifically relating to a water supply pipeline assembly for automotive windshield wipers and an automotive vehicle. Background Technology

[0002] Car wipers clean the windshield, keeping it clear so the driver can see the road better. In current cars, due to design or structural requirements, the wiper nozzles are positioned on the hood. As the hood moves, the washer hoses often need to change direction at large angles. However, due to limited space for the washer hoses and the abrupt changes in direction, the hoses can easily become bent, resulting in problems such as no water flow or insufficient water flow. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a water supply pipe assembly for car windshield wipers and a car, so as to solve the problem that when the wiper nozzle is arranged on the engine hood, and the nozzle moves with the engine hood, the washer water pipe usually needs to be changed at a large angle. Due to the limited space for the arrangement of the washer water pipe, and the rapid change of the water pipe direction, the water pipe is prone to bending, resulting in no water or less water output.

[0004] To achieve the above and other related objectives, this utility model proposes a water supply pipe assembly for automotive windshield wipers, comprising:

[0005] A water supply pipeline and a reversing water bladder installed on the water supply pipeline. The water supply pipeline is fixed to the vehicle body. One end of the water supply pipeline is connected to a centrifugal pump, and the other end is connected to a water spray nozzle.

[0006] The reversing water bladder divides the water supply pipeline into multiple sub-pipelines. The ends of the sub-pipelines are connected to the internal space of the reversing water bladder. The drainage directions of two sub-pipelines connected to the same reversing water bladder are at a certain angle.

[0007] In a preferred embodiment of this utility model, the reversing water bladder is provided with a water inlet and a water outlet, and the axes of the water inlet and the water outlet are parallel to each other or arranged at an angle.

[0008] In a preferred embodiment of this utility model, the water inlet and the water outlet are located on the same side of the reversing water bladder, and their axes are parallel to each other.

[0009] In a preferred embodiment of this utility model, the sub-pipeline includes an inlet pipe and an outlet pipe. The inlet pipe is fixed to the vehicle body and connected to the inlet interface, and the outlet pipe is fixed to the front hood and connected to the outlet interface.

[0010] In a preferred embodiment of this utility model, a plurality of fixing members are spaced apart on the water supply pipeline, and the water supply pipeline is fixedly connected to the vehicle body or the front engine hood through the fixing members.

[0011] In a preferred embodiment of this utility model, the fixing member is detachably connected to the water supply pipeline, and the distance between the plurality of fixing members is adjustable.

[0012] In a preferred embodiment of this utility model, the reversing water bladder is a double-layer water bladder structure, and the water supply pipeline is connected to the internal space of the inner water bladder.

[0013] In a preferred embodiment of this utility model, the reversing water bladder is made of rubber material.

[0014] In a preferred embodiment of this utility model, the reversing water bag and the water supply pipeline are detachably connected.

[0015] This utility model also proposes an automobile, which includes a water supply pipe assembly for automobile wipers as described in any of the above embodiments.

[0016] This utility model proposes a water supply pipe assembly for automotive windshield wipers and an automotive vehicle. It utilizes a reversing water bladder arranged on the water supply pipe, with inlet and outlet ports at different angles and positions. The reversing water bladder is positioned at locations where traditional water supply pipes would otherwise require bending, replacing the traditional bending section and enabling a change in drainage direction, up to 180°. This also solves the problem of limited space in traditional washer hoses, allowing for drainage direction changes within a smaller space. By using the reversing water bladder to change the drainage direction, bending of the water supply pipe is avoided, preventing the impact on water pressure and flow rate that would occur with traditional pipe bends, thus ensuring sufficient water pressure and flow.

[0017] This utility model proposes a water supply pipe assembly for automotive windshield wipers and an automotive vehicle. By using rubber material, which is soft, has a large dimensional tolerance, and is not prone to permanent deformation, it can significantly extend its service life. At the same time, the use of a reversing water bladder facilitates disassembly, replacement, and maintenance, and helps solve the problem of common water pipe blockage. It achieves water supply pipe conduction by squeezing the reversing water bladder. In addition, the reversing water bladder adopts a double-layer structure, which can resist general deformation without affecting water flow, and also provide a certain degree of antifreeze function.

[0025] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0026] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0027] In existing automobiles, due to styling or structural requirements, when the wiper nozzles are positioned on the hood, the nozzles move with the hood, necessitating a sharp reversal of the washer hose. However, due to limited space for the washer hose and the abrupt change in hose direction, bends can easily occur, leading to problems such as insufficient or no water flow. Current solutions typically employ a pre-embedded spring structure within the hose at points of abrupt change in direction. However, research has shown that as the rubber and spring deteriorate and age, this affects the effective response of the water spray. Furthermore, the bends in the hose can negatively impact the spray volume and water pressure. Therefore, this utility model proposes a water supply pipe assembly for automotive windshield wipers and an automotive vehicle, to solve the problem that when the wiper nozzles are arranged on the engine hood, causing the nozzles to move with the engine hood, the washer water pipes often need to be reversed at large angles. Due to the limited space for the arrangement of the washer water pipes and the rapid change in the direction of the water pipes, the water pipes are prone to bending, resulting in no water flow or insufficient water flow. At the same time, it avoids the problem in existing solutions where the effective response of the water spray is affected by the wear and tear of the rubber and springs, and the problem that the water flow and water pressure are affected by the bending of the water pipes.

[0028] Please see Figures 1 to 4 As shown, in this embodiment, the water supply pipeline assembly 100 includes a water supply pipeline 10 and a reversing water bladder 20. The water supply pipeline 10 is fixed to the vehicle body. One end of the water supply pipeline 10 is connected to a centrifugal pump, and the other end is connected to a spray nozzle. The centrifugal pump pumps windshield washer fluid through the water supply pipeline 10 and sprays it out through the spray nozzle. The reversing water bladder 20 is disposed on the water supply pipeline 10 and divides the water supply pipeline 10 into multiple sub-pipes. The end of each sub-pipe is connected to the internal space of the reversing water bladder 20. The drainage directions of the two sub-pipes connected to the same reversing water bladder 20 are at a certain angle. The reversing water bladder 20 can realize the change of drainage direction, and can realize the change of any direction while avoiding bending of the water supply pipeline 10. This avoids the impact on water pressure and water output caused by bending of traditional water pipes, and ensures water pressure and water volume.

[0029] Please see Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, the reversing water bladder 20 is provided with an inlet port 21 and an outlet port 22. The axes of the inlet port 21 and the outlet port 22 are parallel to each other or arranged at an angle. For example, taking the reversing water bladder 20 as a cylindrical shape, when the inlet port 21 is located on the side of the reversing water bladder 20 and the outlet port 22 is located on the end face of the reversing water bladder 20, and the axes of the inlet port 21 and the outlet port 22 are perpendicular to each other, it can achieve a 90° change in drainage direction. When the inlet port 21 is located on the first side of the reversing water bladder 20 and the outlet port 22 is located on the second side of the reversing water bladder 20, the first side and the second side are two adjacent sides of the reversing water bladder 20, and the inlet port 21 and the outlet port 22 are arranged at an angle. When the axes of the interfaces 22 are perpendicular to each other, the drainage direction can be changed by 90° in another plane. When the inlet interface 21 and the outlet interface 22 are located on the same side of the reversing water bag 20, and the axes of the inlet interface 21 and the outlet interface 22 are parallel to each other, the drainage direction can be changed by 180°. That is, the design of the reversing water bag 20 can realize the change of drainage direction in any direction. At the same time, the reversing water bag 20 is arranged at the position where the water supply pipe 10 originally needs to be bent, so as to replace the original pipe bend, so that the water supply pipe 10 does not need to be bent, avoiding the impact on water pressure and water output after the bending of traditional water pipes, ensuring water pressure and water volume, and solving the problem of limited space for the layout of traditional washing water pipes, so that the drainage direction can be changed in a small space.

[0030] Please see Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the water supply pipeline 10 is divided into sub-pipelines including an inlet pipeline 11 and an outlet pipeline 12. The inlet pipeline 11 is fixed to the vehicle body, with one end connected to the centrifugal pump and the other end connected to the inlet port 21 of the reversing water bladder 20. The outlet pipeline 12 is fixed to the front hood, with one end connected to the spray nozzle and the other end connected to the outlet port 22 of the reversing water bladder 20. The water flow direction from the inlet pipeline 11 into the reversing water bladder 20 and the water flow direction from the reversing water bladder 20 into the outlet pipeline 12 are 180° apart.

[0031] Please see Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, multiple fasteners 13 are provided on the water supply pipe 10. The water supply pipe 10 is fixedly connected to the vehicle body or the front hood via the fasteners 13. Specifically, the inlet pipe 11 is fixedly connected to the vehicle body via the fasteners 13, and the outlet pipe 12 is fixedly connected to the front hood via the fasteners 13. The design of the reversing water bladder 20 solves the problem of bending of the traditional outlet pipe as the hood moves, ensuring water pressure and volume. Furthermore, the fasteners 13 are detachably connected to the water supply pipe 10, and the distance between the multiple fasteners 13 is adjustable, allowing it to adapt to different installation conditions and be compatible with different vehicles.

[0032] Please see Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the reversing water bladder 20 is designed as a double-layer water bladder structure, wherein there is a certain gap between the inner water bladder 23 and the outer water bladder 24. The water supply pipeline 10 is connected to the internal space of the inner water bladder 23. The double-layer water bladder structure can resist general deformation, thereby avoiding affecting the water flow. At the same time, the double-layer water bladder structure can also play a certain anti-freezing function, preventing the liquid from freezing and clogging the water supply pipeline. In this embodiment, the reversing water bladder 20 is made of rubber material. The rubber material is soft and has a certain degree of elasticity, which allows it to have a large dimensional tolerance, making it easy to install and not prone to permanent deformation, thus extending its service life. Furthermore, due to its rubber material, the reversing water bladder 20 can be squeezed. For general water pipe blockage problems, squeezing the reversing water bladder can realize the conduction of the water supply pipeline. Further, the reversing water bladder 20 and the water supply pipeline 10 are detachably connected, facilitating disassembly, replacement, and maintenance operations.

The water supply pipe assembly has the same or similar structure as the water supply pipe assembly 100 described in the above embodiments. To avoid repetition, it will not be described again here.
