The invention will be more fully understood from the following detailed description of exemplary embodiments, Kind of components. Wherein: FIG. 1 is a schematic view showing a wiper blade having an adapter according to an embodiment of the present invention, wherein the adapter is not attached to the wiper strip, and the wiper strip is partially omitted in the drawing; FIG. 2 is another One angle shows a schematic view of the wiper board shown in Fig. 1, in which the top surface of the wiper board is more displayed; and Fig. 3 shows a schematic view of the wiper board shown in Fig. 2 after the assembly is completed, in which the adapter has been mounted to Wiper strip; Fig. 4 shows a schematic view of the wiper board shown in Fig. 3 from another angle, in which the bottom surface of the wiper board is more shown; Fig. 5 shows the transition portion of the wiper board shown in Fig. 3 from the bottom side. Schematic; and Figure 6 shows a schematic cross-sectional view along line AA shown in Figure 3.

To assist those skilled in the art to understand the adapters claimed in the present invention, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 6, a wiper board 100 according to an embodiment of the present invention includes a wiper strip 2 and an adapter 1. In a preferred embodiment, the wiper blade 100 further includes a connector 3 as shown.

The adapter 1 includes a top portion 10 and two side portions 12 extending downwardly from laterally opposite sides of the top portion 10, and a receiving space 13 having a downward opening is formed between the two side portions 12, and each side portion 12 is formed. The support portion 14 that protrudes toward the accommodating space 13 is provided, and each of the support portions 14 is provided with a buckle portion that allows the position from the accommodating space 13 to the laterally outer side. 140. Preferably, the locking portion 140 has a groove shape recessed from the receiving space 13 to the laterally outer sides, and a guiding surface 142 is disposed below the locking portion 140 of the supporting portion 14 . The guide surface 142 is gradually inclined inward from the lower portion to the upper portion, that is, the lower portion of the guide surface 142 is located more outward than the position of the upper portion thereof. The wiper strip 2 comprises an elongated spring leaf 20. At the time of mounting, the wiper strip 2 is inserted into the accommodating space 13 from the lower opening, and the spring piece 20 is attached into the hooking portion 140 from the bottom to the top via the guide surface 142. Since the guide surface 142 is gradually inclined inward from the lower portion to the upper portion, the spring piece 20 applies an elastic pressing force to the support portion 14 when passing through the guide surface 142. When the position of the hook portion 140 of the groove shape is reached, the guide surface 142 no longer contacts the spring piece 20, thereby releasing the elastic force so that the spring piece 20 automatically enters the groove-shaped hook portion 140 in the lateral direction. Referring to the cross-sectional view shown in FIG. 6, the spring piece 20 is fixed in the buckle portion 140, and the buckle portion 140 restricts the displacement of the spring piece 20 in the up and down direction. Therefore, the mounting of the adapter 1 on the wiper board 100 can be easily accomplished in one step, and the adapter 1 adapter 1 can be stably fixed to the wiper strip 2, and the wiper panel 100 can exhibit good performance.

The connector 3 is provided with a pivot 34, and the connector 3 is fixed to the spring piece 20 and located in the accommodating space 13. Referring to the preferred embodiment shown in FIG. 5, each side portion 12 of the adapter 1 is provided with two support portions 14, which are elongated in the up and down direction. On the one hand, the two support portions 14 can provide a good lateral limit for the connector 3; on the other hand, the pivot 34 between the two support portions 14 can provide a longitudinal limit. Preferably, the adapter 1 further includes end walls 18 extending downwardly from opposite longitudinal ends of the top portion 10, and the lateral sides of each end wall 18 are connected to the two side portions 12, respectively. That is to say, the two end walls 18 and the two side portions 12 respectively surround the front, rear, left and right sides of the accommodating space 13. The wiper strip 2 may further include an elongated spoiler 22, and the lower edge of the middle portion of each end wall 18 may be provided with the spoiler 22 The notch 180 of the shape, the spoiler 22 is mounted in the notch 180. Thus, not only can the spoiler 22 be restrained and protected in the notch 180, but the adapter 1 and the wiper strip 2 form a compact and beautiful overall.

In a preferred embodiment, as shown, the accommodating space 13 of the adapter 1 is further provided with two reinforcing walls 11 extending at intervals in the longitudinal direction, and the reinforcing wall 11 is integrally connected to the end wall 18. This structural design can effectively increase the structural strength of the adapter 1, so that the adapter 1 does not need to be manufactured with expensive materials and processes, and the adapter 1 can be integrally formed of plastic at a lower cost. The lower edge of the reinforcing wall 11 is provided with a retaining groove 110, and after the installation is completed, the pivot 34 of the connector 3 is located in the retaining groove 110. Therefore, not only can the relative position of the connector 3 and the adapter 1 be defined, but also the connector 3 and the adapter 1 can be compactly coupled.

Preferably, the adapter 1 is provided with a through hole 15 penetrating through the side portion 12 and the reinforcing wall 11. When the wiper arm is installed, the connecting arm of the wiper arm can be transversely passed through the through hole 15 to realize the connection of the wiper arm to the adapter 1. In a preferred embodiment, the column 16 is integrally formed between the side portion 12 and the reinforcing wall 11 , and the through hole 15 extends through the column 16 . The top 10 of the adapter 1 is provided with a seating opening 19 for injection molding to form the adapter 1 for the mold for forming the top surface of the cylinder 16 to pass through the opening 19 during injection molding.

In a preferred embodiment, the connector 3 includes a metal base portion 30 and two side walls 32 that are integrally bent upwardly from laterally opposite sides of the base portion 30. The pivot shaft 34 extends through the two side walls 32 and is fixed. In the two side walls 32, the side wall 32 is defined between the reinforcing wall 11 and the support portion 14. The base 30 and the two side walls 32 may be integrally stamped by a metal stamping process, and a circular hole (not shown) for mounting the pivot 34 is punched in each side wall 32, and the cylindrical pivot 34 is passed through two The round holes of the side walls 32 are fixed by suitable means such as interference fit, riveting or welding.

It should be noted that those skilled in the art can understand that in the present specification, "top", "bottom", "upper", "lower", "longitudinal", and "lateral" are used for convenience of description. The term, which merely denotes a relative positional relationship, does not mean an absolute spatial position. For example, the orientation terms "top" and "upper" refer to the opposite directions of "bottom" and "lower", while the orientation term "longitudinal" refers to the length direction of the object, and "lateral" refers to the "longitudinal" phase. Vertical and usually perpendicular to the up and down direction.

The above specific embodiments are merely illustrative of the invention, and are not intended to limit the scope of the invention, and various changes and modifications can be made without departing from the scope of the invention. The technical solution is also within the scope of the invention, and the scope of the invention should be defined by the claims.
