Technical Field

[0001] This utility model relates to a wiper assembly, and more particularly to a wiper assembly for connecting a wiper arm and a rocker arm, and a wiper having the wiper assembly. Background Technology

[0002] Current windshield wipers consist of a wiper arm with a mounting bracket connected to a wiper connector. This connector can be linked to a rocker arm, allowing the vehicle to control the rocker arm's movement to actuate the wiper blades on the wiper arm and remove water from the windshield. However, the existing wiper connectors and mounting brackets cannot be separated without causing damage, making maintenance and replacement of wiper connectors inconvenient. Therefore, existing windshield wipers and their components definitely need improvement. Utility Model Content

[0003] To solve the above problems, the purpose of this utility model is to provide a wiper assembly and a wiper having the wiper assembly, so that the wiper and the rocker arm can be easily assembled and disassembled.

[0004] The directional terms or similar terms used throughout this utility model, such as "front", "back", "left", "right", "top", "bottom", "inner", "outer", "side", etc., are mainly for reference to the directions in the accompanying drawings. Each directional term or similar term is only used to assist in explaining and understanding the various embodiments of this utility model and is not intended to limit this utility model.

[0005] The use of the quantifiers “a” or “an” for the elements and components described throughout this utility model is merely for convenience and to provide the general meaning of the scope of this utility model; in this utility model, it should be interpreted as including one or at least one, and a single concept also includes multiple cases, unless it clearly means otherwise.

[0006] The terms "combination," "integration," or "assembly" used throughout this utility model mainly include those that allow for separation without damaging the components after connection, or those that make the components inseparable after connection. Those skilled in the art can choose the appropriate term based on the material of the components to be connected or the assembly requirements.

[0007] The wiper assembly of this utility model includes: a fixing base having an assembly groove, the assembly groove having at least one limiting member, the at least one limiting member having a gap with a bottom surface of the assembly groove to form a limiting space, the fixing base having a fastening member, the fastening member and the at least one limiting member being located at opposite ends of the assembly groove, the fastening member having an elastic arm and a spring-loaded portion, a limiting end of the spring-loaded portion having a gap with the bottom surface of the groove; and a wiper connector having an assembly portion, one end of the assembly portion being located in the limiting space, the limiting end of the spring-loaded portion pressing against the other end of the assembly portion.

[0008] Therefore, the wiper assembly of this utility model can easily release the limiting effect of the mounting slot of the fixing seat on the wiper connector by pressing the spring part of the fastener. The wiper connector and the fixing seat can be separated without damaging the structure. The wiper connector and the fixing seat can be easily disassembled and assembled, so as to facilitate maintenance, repair and replacement of the wiper arm.

[0009] The assembly slot has at least one positioning block located on the bottom surface of the slot, and the assembly part has at least one positioning groove facing the fixing seat.

[0056] To make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments of this utility model are described below in detail with reference to the accompanying drawings; in addition, the same symbols in different drawings are considered to be the same and their descriptions will be omitted.

[0057] Please refer to Figure 1 , Figure 2 As shown, it is a preferred embodiment of the wiper assembly of the present invention, including a fixing base 1 and a wiper connector 2, the wiper connector 2 being coupled to the fixing base 1.

[0058] The mounting base 1 can be attached to a brush rod T, which may have a spring piece T1. The spring piece T1 is attached to a brush blade T2. The mounting base 1 can be attached to the spring piece T1 by means of snap-fit ​​or welding, for example, by using several fasteners T3 to snap the mounting base 1 to the brush rod T. This utility model is not limited to this. The mounting base 1 may have an assembly groove 11 and a connecting part 12. The assembly groove 11 can be used to connect with the wiper connector 2, and the connecting part 12 is used to connect with the brush rod T. Specifically, the mounting base 1 may have a first end 1a and a second end 1b opposite to each other. The assembly groove 11 has at least one limiting member 13, which may be adjacent to the first end 1a. The at least one limiting member 13 may be a protrusion, which may protrude from the inner wall of the assembly groove 11 so that the at least one limiting member 13 can be located in the assembly groove 11. There may be a gap between the at least one limiting member 13 and a groove bottom surface 11a of the assembly groove 11 to form a limiting space S. In this embodiment, the at least one limiting member 13 may be two protrusions. In this way, the at least one limiting member 13 can be used to limit the wiper connector 2 in a vertical direction D. Preferably, the vertical direction D may be perpendicular to the groove bottom surface 11a.

[0059] Preferably, the assembly groove 11 may have at least one positioning block 111, which may be located on the bottom surface 11a of the groove, and may be used to position the wiper connector 2. This invention does not limit the shape or position of the at least one positioning block 111; it may be, for example, a rectangular block, a conical block, a cylindrical block, or a rib, or other geometrically shaped block. Furthermore, the at least one positioning block 111 may or may not be adjacent to the inner peripheral wall of the assembly groove 11. Preferably, at least one positioning block 111 may be located on the bottom surface 11a of the groove and not adjacent to the inner peripheral wall of the assembly groove 11. This prevents relative displacement between the wiper connector 2 and the assembly groove 11 (described in detail later).

[0060] The mounting base 1 has a fastening member 14 adjacent to the second end 1b. The fastening member 14 and the at least one limiting member 13 can be located at opposite ends of the assembly groove 11, and the fastening member 14 and the at least one limiting member 13 together can fix the wiper connector 2 to the assembly groove 11. Furthermore, the fastening member 14 has an elastic arm 15, one end of which can have a spring-loaded portion 16. Notably, the spring-loaded portion 16 can extend to form a limiting end 16a, allowing a gap between the limiting end 16a and the bottom surface 11a of the assembly groove 11. The spring-loaded portion 16 can have a pressing end 16b, which is located at opposite ends of the pressing end 16, along with the limiting end 16a. Thus, when the pressing end 16b is subjected to force, the elastic arm 15 can bend elastically.

[0061] Please continue reading. Figure 1 , Figure 2 As shown, the wiper connector 2 may have an assembly portion 21, through which the wiper connector 2 can be attached to the assembly groove 11. When the assembly portion 21 is located in the assembly groove 11, one end of the assembly portion 21 may be located in the limiting space S between the at least one limiting member 13 and the bottom surface 11a of the groove. For example, the at least one limiting member 13 may abut against an upper surface 21a of the assembly portion 21. The other end of the assembly portion 21 may be located between the spring-loaded portion 16 and the bottom surface 11a of the groove, so that the limiting end 16a of the spring-loaded portion 16 may abut against the upper surface 21a of the assembly portion 21. In this way, the at least one limiting member 13 and the spring-loaded portion 16 of the fastening member 14 can respectively form the vertical direction D limiting at opposite ends of the assembly portion 21.

[0062] In this embodiment, the upper surface 21a of the assembly part 21 may be recessed with at least one groove 22. This groove 22 can be positioned opposite the at least one limiting member 13, allowing the at least one limiting member 13 to abut against the bottom surface of the groove 22 and thus limit the assembly part 21. Preferably, the at least one groove 22 may have a groove shape corresponding to the at least one limiting member 13 to provide better abutment stability. In this embodiment, the at least one limiting member 13 may have a guide surface 13a facing the limiting space S, and the bottom of the at least one groove 22 is an arc surface corresponding to the guide surface 13a. This allows the assembly part 21 to be easily inserted into and easily removed from the limiting space S.

[0063] Furthermore, the assembly part 21 may have at least one positioning groove 23 facing the fixing base 1. The at least one positioning groove 23 may be aligned with at least one positioning block 111 of the assembly groove 11 in the vertical direction D, and the at least one positioning groove 23 may have a corresponding groove shape to the at least one positioning block 111. In this way, after the assembly part 21 is combined with the assembly groove 11, it can be positioned by the at least one positioning groove 23, which can reduce the relative displacement between the assembly part 21 and the assembly groove 11. It is worth noting that when the at least one positioning block 111 is not adjacent to the inner peripheral wall of the assembly groove 11, the at least one positioning groove 23 can form a limit relative to the circumferential surface of the at least one positioning block 111, thereby reducing the relative displacement between the assembly part 21 and the assembly groove 11 in the front-back direction and the left-right direction.

[0064] Please refer to Figure 4 , Figure 5 , Figure 6As shown, the wiper connector 2 may have an adapter 24 located on the upper surface 21a of the assembly part 21. The adapter 24 is used to engage a rocker arm P. In this embodiment, the adapter 24 may have opposing side plates 25, with a connecting post 26 located between the side plates 25. Both ends of the connecting post 26 are respectively engaged with the side plates 25. Thus, a hook P1 of the rocker arm P can be hooked and engaged with the connecting post 26. The hook P1 can be positioned between the side plates 25 by a fastener P2 or similar component corresponding to the hook P1 without being disengaged by the adapter 24. In another embodiment, the adapter 24 may have a pivot seat 27 with two opposing pivots 271, allowing for the assembly of a rocker arm with a pivot hole structure. Furthermore, as... Figure 5 , Figure 6 Different types of pivot seats 27 are disclosed to be assembled and combined with existing rocker arms that have corresponding assembly slots.

[0065] Please refer to Figure 3 , Figure 4 As shown, according to the aforementioned structure, when the fixing base 1 and the wiper connector 2 are engaged, one end of the assembly part 21 can be inserted into the limiting space S. Through the elastic deformation of the elastic arm 15 of the fastener 14, the other end of the assembly part 21 can be forced into the assembly groove 11, and the elastic return of the elastic arm 15 allows the limiting end 16a of the spring-loaded part 16 to press against the assembly part 21. This positions the wiper connector 2 in the assembly groove 11.

[0066] Conversely, when you want to remove the wiper connector 2 from the assembly slot 11, you can press the pressing end 16b of the spring-loaded part 16. After the pressing end 16b is subjected to force, the elastic arm 15 of the fastener 14 can bend elastically, so that the limiting end 16a does not press against the assembly part 21, thereby releasing the limit of the wiper connector 2 in the vertical direction D, so that the wiper connector 2 can be removed from the assembly slot 11.

[0067] In summary, the wiper assembly of this utility model can easily release the limiting effect of the mounting slot of the fixing seat on the wiper connector by pressing the spring part of the fastener. The wiper connector and the fixing seat can be separated without damaging the structure, and the wiper connector and the fixing seat can be easily disassembled and assembled, so as to facilitate maintenance, repair and replacement of the wiper arm.
