[0002] Windshield wipers are an essential component of automobiles, used to wipe away rainwater, snow, or other debris from the windshield to prevent these objects from obstructing the driver's view. Currently, most windshield wipers used in automobiles consist primarily of a wiper arm, a wiper blade, and a wiper connector connecting the two. A wiper generally comprises a steel blade, a rubber strip, and a protective sleeve connected together. The wiper connector is mounted on the wiper mount, which is fixed to the center of the wiper blade. With the rapid development of the automotive industry in China, various types of wiper arms have emerged, requiring different wiper mounts and connectors to be designed to accommodate these different vehicle models.

[0003] Therefore, if the wiper base is damaged, the entire wiper base needs to be replaced, resulting in unnecessary waste. Utility Model Content

[0032] Combination Figure 1 and Figure 2 As shown, this embodiment provides a wiper assembly connection structure, including a base 1 and an adapter 2 that are detachably connected together. The base 1 and the adapter 2 are connected by a snap-fit ​​connection component, a limiting connection component, and a fixing connection component, and all of these components are detachable.

[0033] In this design, base 1 and adapter 2 combine to form the wiper base. Base 1 and adapter 2 are detachably connected. Typically, base 1 is fixed to the wiper blade's steel plate, and adapter 2 connects to the wiper connector. If adapter 2 or the wiper connector is damaged, only adapter 2 needs to be replaced; the entire wiper base does not need to be replaced. Furthermore, base 1 and adapter 2 are connected via a snap-fit ​​connection assembly, a limiting connection assembly, and a fixing connection assembly. The snap-fit ​​connection assembly guides and secures the connection, while the fixing connection assembly further secures base 1 and adapter 2. Both the snap-fit ​​and fixing connections also secure the ends of base 1 and adapter 2, respectively. The limiting connection assembly limits the movement of base 1 and adapter 2 along the wiper's swing direction. All three components—snap-fit, limiting, and fixing—are detachable, allowing for separation between base 1 and adapter 2.

[0034] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the snap-fit ​​connection assembly specifically includes a mounting hole 101 at one end of the base 1 and a mounting block 201 at one end of the adapter 2, with the mounting block 201 connected to the mounting hole 101. Further, a snap-fit ​​plate 105 protrudes from the side of the mounting hole 101 away from the adapter 2; a baffle is provided at one end of the mounting block 201; the baffle is snap-fitted onto the snap-fit ​​plate 105. By snap-fitting the baffle onto the snap-fit ​​plate 105, a connection is formed between the snap-fit ​​connection assemblies, and the distance between the base 1 and the adapter 2 is limited along the length of the wiper.

[0035] Regarding the limiting connection assembly, specifically the limiting connection assembly includes a limiting groove 102 formed on the base 1 and a connecting member limiting block 202 disposed on the adapter 2. The connecting member limiting block 202 is adapted to be connected to the limiting groove 102, thereby limiting the base 1 and the adapter 2 along the wiper swing direction.

[0036] As a further improvement, the limiting connection assembly also includes an adapter limiting groove 203 formed on the adapter 2 and a limiting block 103 disposed on the base 1. The limiting block 103 is adapted to be connected to the adapter limiting groove 203. Moreover, the limiting groove 102 is formed on the side near the limiting block 103, and the adapter limiting groove 203 is close to the side near the adapter limiting block 202. After the limiting connection assembly is connected, the limiting block 103 and the adapter limiting block 202 are close to each other, so that the limiting block 103 and the adapter limiting block 202 play a role in mutual positioning and limiting.

[0037] In addition, two limit connection components are provided, symmetrically arranged on both sides of the centerline of the wiper length direction, to improve the stability of the limit connection components.

[0038] Regarding the fixed connection assembly, specifically, the fixed connection assembly includes a fixed shaft 104 disposed at the other end of the base 1 and a slot 204 formed at the other end of the adapter 2, wherein the fixed shaft 104 is adapted to be connected in the slot 204. As a preferred embodiment, the slot 204 is arc-shaped, and the arc angle is greater than 180°, so that the fixed shaft 104 will not fall out when it is inserted into the slot 204, and the fixed shaft 104 is fixed by the shape of the slot 204 itself.

[0039] Preferably, the limiting connection component is located between the snap-fit ​​connection component and the fixed connection component. The snap-fit ​​connection component and the fixed connection component are respectively disposed at both ends of the base 1 and the adapter 2, fixing the connection between the base 1 and the adapter 2, making the connection between the two more stable, and limiting the connection between the two along the length direction of the wiper.

[0040] To improve the adaptability of the wiper assembly connection structure, the adapter 2 is also provided with a connecting post 205 for connecting with the wiper connector. Different types of wiper connectors can be connected through the connecting post 205.

[0041] Combined Figure 1 and Figure 2 As shown, when connecting the base 1 and the adapter 2, the mounting block 201 extends into the mounting hole 101, so that the baffle at one end of the mounting block 201 is connected to the snap-fit ​​plate 105. After the baffle is connected to the snap-fit ​​plate 105, the connection between the base 1 and the adapter 2 is positioned. At this time, the positioning between the limiting connection component and the fixed connection component is completed. As long as the base 1 and the adapter 2 are pressed together to bring them closer to each other, the limiting connection component and the fixed connection component can cooperate with each other to achieve mutual connection. The structure is simple and the connection is convenient.
