[0002] A windshield wiper is a tool used to clean the glass of a vehicle to prevent rain and other dirt from affecting vision. It is an important component to ensure driving safety. Traditional wipers are connected and supported by two connecting rods. Since the connecting ends of the connecting rods require high precision and surface morphology, they are mostly formed in one piece by stamping. However, during the production process, different car models will require wipers of different sizes, and the corresponding wiper connecting rods also have size differences. What's more, the right-hand drive models overseas have greater requirements for wiper connecting rods than traditional domestic models. The above production scenarios all require the creation of new wiper connecting rod parts, and the provision of new molds, inspection fixtures and other tooling will increase the cost of the entire vehicle and extend the development cycle. At the same time, the poor versatility of the wiper connecting rod also makes it difficult to maintain its stable product quality.

[0003] Therefore, how to improve the versatility of wiper connecting rods and reduce vehicle production costs and cycles is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0022] Vehicle wipers are indispensable components to ensure driving safety. However, due to frequent vehicle model updates, different project requirements, and even regulatory requirements in different countries, there will be structural differences in wipers. Some stamped structural parts in the wipers require new molds for production when the assembly is updated, which not only increases the production cost of the vehicle, but also imposes a certain burden on the vehicle's R&D and production cycle.

[0023] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0024] See also Figure 1 and Figure 2The wiper connecting rod provided by the embodiment of the utility model mainly includes a connecting rod 10, a first end head 20 and a second end head 30. The three components are preferably produced separately, so that each of them is independently equipped with production equipment and has an independent part number, which is easy to realize mass production and storage. At the same time, the three components are assembled into an integrated structure in advance or on the line during the assembly process to realize the function of the wiper connecting rod. The separate production can determine the structure of the first end head 20 and the second end head 30, which are more difficult to produce, and the adaptation length requirement of the wiper connecting rod is achieved by adjusting the size of the connecting rod 10. On the basis of the above structure, the first end head 20 and the second end head 30 are respectively assembled and connected to the opposite sides of the connecting rod 10, and at the same time, connecting holes 40 are respectively opened on the first end head 20 and the second end head 30, so that the wiper connecting rod passes through the connecting holes 40 on the first end head 20 and the second end head 30, so that the two ends have the function of connecting with other structural parts. It should be noted that the sizes of the connecting holes 40 on the first end 20 and the second end 30 are preferably equal, so that the wiper connecting rod provided in this embodiment can be connected to other structural components through a connecting piece of a single size. At the same time, the connecting hole 40 can allow bolts to pass through to cooperate with nuts for connection and locking; it can also have an internal threaded structure to directly connect with bolts or screws.

[0025] On the basis of the above structure, the first end 20 and the second end 30 are both structures that contract toward one side of the connecting rod 10 to form a compact structure, which not only saves space, but also enhances the overall stability, so that the forces at both ends of the wiper connecting rod can be smoothly transmitted to the middle connecting rod 10 position. The connecting rod 10 is designed as a one-way rod that is easy to produce and manufacture. It should be noted that the one-way rod here specifically refers to the connecting rod 10 having the same cross-sectional structure in its length direction, thereby ensuring the consistency and stability of the connecting rod at different positions. It should be noted that the one-way rod is a structural part commonly used in the workshop production process and has a standardized production process. It can be produced by a rolling process without the need for molds, inspection fixtures and other tooling. It only needs to determine the required length size to quickly produce it. The process is simple and efficient.

[0026] On the basis of the above-mentioned embodiments, the wiper connecting rod can be produced in a relatively standardized manner. In order to meet the production requirements of the complex surface structure of the first end 20 and the second end 30, the first end 20 and the second end 30 are integrally formed by a stamping process, and a mold and a check fixture are provided to ensure the qualified rate of the product. The connecting rod 10 can be produced by a rolling process. When there are differences in vehicle models and design specifications, the first end 20 and the second end 30 provided at both ends of the wiper connecting rod for cooperating with other structural components are consistent in structure, and the length of the wiper connecting rod is adjusted by connecting rods 10 of different sizes. The first end 20 and the second end 30 only need to be provided with molds and produced separately. After the connecting rod 10 of the required length is produced for the corresponding vehicle model, it can be connected and assembled to form a wiper connecting rod that meets the use requirements.

[0027] The wiper connecting rod provided by the embodiment of the utility model has a split design of the connecting rod 10, the first end head 20 and the second end head 30, so that when the wiper connecting rod has a size difference due to the difference in vehicle models, there is no need to adjust the structure of the first end head 20 and the second end head 30, but the size of the wiper connecting rod can be adjusted by adjusting the size of the connecting rod 10. On this basis, the first end head 20 and the second end head 30 can be standardized after a single mold opening, and there is no need to open a new mold when the vehicle model changes. Instead, the size is adjusted by the connecting rod 10 with a simple production process that does not affect the production cycle, thereby improving the standardization of the wiper connecting rod in the production process, improving production efficiency, reducing costs, and enhancing the versatility and interchangeability of the product.

[0028] In order to further optimize the above technical solution, in some embodiments of the utility model, the end of the first terminal 20 that contacts the connecting rod 10 includes a contraction section 210 and an extension section 220, wherein the contraction section 210 is composed of two opposite curved outer wall surfaces, which not only provide a beautiful appearance, but also allow the force to be smoothly transmitted while satisfying the size change of the first terminal 20, reducing the risk of stress concentration and improving the smoothness of the wiper during movement. The extension section has the same cross-section as the connecting rod 10 and is connected to the connecting rod 10 by a fixed connection. This equal-section extension connection structure can make the connection between the first terminal 20 and the connecting rod 10 more secure and improve the stability of the overall structure. In addition, the design of the contraction section 210 and the extension section 220 also allows the first terminal 20 to achieve a more flexible installation angle without sacrificing strength to meet the installation requirements of different models.

[0029] It should be noted that the structure of the second terminal 30 is the same as that of the first terminal 20, which will not be described in detail herein.

[0030] In order to further enhance the versatility of the wiper connecting rod provided by the embodiment of the utility model, the connecting rod 10 is composed of an inner tube and an outer tube, and the inner tube and the outer tube are arranged to slide relative to each other to achieve the adjustment of the length of the wiper connecting rod. Specifically, a limiting protrusion is provided on the inner tube, and at least two limiting holes are provided on the outer tube at intervals, and these limiting holes can be locked with the limiting protrusions to ensure that the connecting rod 10 can be stably maintained after being adjusted to a specific length to prevent sliding or displacement during use. The above structure allows the user to easily adjust the length of the connecting rod according to actual needs, providing higher adaptability and flexibility. The cooperation of the limiting protrusion and the limiting hole can ensure the stability of the connecting rod 10 after adjustment.

[0031] It should be noted that the structural design of the inner tube and the outer tube enables the connecting rod 10 to have at least two length adjustment functions, and the designer can design the position of the limit hole according to the length requirements of common vehicle models, so that a single connecting rod 10 can meet the requirements of two lengths of wiper connecting rods. Similarly, more limit holes can be provided to meet more diverse length requirements of wiper connecting rods.

[0032] Furthermore, in some embodiments of the utility model, the connection method between the connecting rod 10 and the first end 20 is an inserted snap-on connection. Specifically, a mounting groove is provided on the side wall of the first end 20, and an elastic mounting buckle is provided on the connecting rod 10. These mounting buckles are locked with the mounting groove to achieve quick assembly. The above connection method can simplify the assembly process, improve the assembly efficiency, and ensure the stability of the connection. At the same time, the side wall of the connecting rod 10 is also provided with an unlocking button, and the mounting port is an elastic snap-on structure, which can shrink under the pressing action of the unlocking button and unlock with the mounting groove, so as to realize the disassembly of the connecting rod 10 and the first end 20. The snap-on connection structure can not only maintain the stable connection between the connecting rod 10 and the first end 20, but also can realize disassembly to meet the needs of reuse, and it is more convenient during maintenance and replacement of some structural parts.

[0033] It should also be noted that the connection structure between the connecting rod 10 and the second end 30 is the same as the above structure, so that the connecting rod 10 and the second end 30 have a convenient disassembly and assembly function, which will not be repeated herein.

[0034] In order to make the connecting rod 10 have good rigidity, in some embodiments of the present invention, the connecting rod 10 is a U-shaped plate structure and is made by rolling to have uniform thickness and strength. The U-shaped structure can also reduce the use of materials through its open structure, thereby reducing the overall weight and improving the flexibility and response speed of the connecting rod. In addition, the edge of the U-shaped trough is specially treated to enhance its wear resistance and deformation resistance to ensure stability in long-term use.

[0035] On the basis of the above embodiment, a plurality of reinforcing ribs are further arranged in the U-shaped groove area of ​​the connecting rod 10, and the reinforcing ribs are fixed by interval welding, which can not only enhance the rigidity and bending resistance of the connecting rod 10, but also effectively prevent deformation and damage when bearing a large load. The design of the reinforcing ribs takes into account the mechanical distribution, and is preferably evenly arranged at fixed intervals to ensure that the entire connecting rod 10 can evenly bear the force in all directions, improve the rigidity and stability of the overall structure, and extend the service life of the product.

[0036] Furthermore, in some embodiments of the present invention, the first end head 20 and the second end head 30 are of completely identical structure, so that only one mold is needed to realize the production of the first end head 20 and the second end head 30, which simplifies the production process and reduces the manufacturing cost. The lengths of the first end head 20 and the second end head 30 are both 80mm-85mm, which are optimized according to the sizes of wiper arms of various models, ensuring a close fit and optimal performance between the end head and the wiper arm. Accurate length control helps to ensure the applicability and performance of the wiper connecting rod on different models, and also facilitates inventory management and logistics distribution.

[0037] In addition, in some embodiments of the utility model, the first end 20 and the second end 30 are both fixedly connected to the connecting rod 10 by two-way welding. As an efficient welding technology, two-way welding provides uniform welding quality and high connection strength, ensuring the stability and durability of the connecting rod in long-term use. In addition, two-way welding has a high degree of automation, and can reduce the influence of human factors on welding quality and improve production efficiency by robot welding.

[0038] like Figure 3 As shown, some embodiments of the utility model further provide a wiper assembly, which includes a wiper motor 50, a fixing seat 60 and two wiper links 70 provided in any of the above embodiments, wherein a pair of connecting holes 40 of the two wiper links 70 are aligned and connected by a pin passing through the connecting holes 40, and the connecting holes 40 at both ends of the wiper links 70 are used to connect to the fixing seat. It should be noted that since the above wiper links 70 have the above technical effects, the wiper assembly also has corresponding effects, which will not be described in detail here.

[0039] Furthermore, some embodiments of the utility model also disclose a vehicle, which uses the wiper assembly provided by the above embodiments to clean the glass. Since the above wiper assembly has the above effects, the above vehicle also has corresponding effects, which will not be repeated herein. It should be noted that the above vehicle may be a pure electric vehicle, a hybrid vehicle or a fuel vehicle, etc.

[0040] It should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other.

[0041] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
