DETAILED DESCRIPTION

(6) The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

(7) Please refer to FIGS. 1 and 2, which are a perspective schematic view and an exploded view of the wiper assembling structure of the disclosure. The disclosure provides a wiper assembling structure 1 to be connected with a driving arm 2. The wiper assembling structure 1 includes a fixing seat 10, an accessory seat 20, a blade set 30 and a protective cover 40. The accessory seat 20 is connected in the fixing seat 10 by means of interference fit. The blade set 30 is connected on the bottom of the accessory seat 20. In the embodiment, the accessory seat 20 is disposed with a pivot 201. Also, the protective cover 40 is disposed with a through hole 401. The protective cover 40 is connected to the accessory seat 20 by passing the pivot 201 through the through hole 401 so as to complete the wiper assembling structure 1. More details will be described below.

(8) Please refer to FIGS. 3-6, which are an exploded view of the fixing seat and the accessory seat, a perspective schematic view of the wiper assembling structure after removing the protective cover and two assembled cross-sectional views of the wiper assembling structure of the disclosure after removing the protective cover. In an embodiment of the disclosure, the fixing seat 10 includes a shell seat 11 and multiple pressing blocks 12 disposed in the shell seat 11. The accessory seat 20 includes a bottom plate 21 and two side plates 22 perpendicularly extended from the bottom plate 21. Each of two ends of each side plate is formed with multiple protrusive sheets 23. The accessory seat 20 is positioned in the fixing seat 10 by inserting the protrusive sheets 23 into the shell seat 11 to be pressed by the pressing blocks 12.

(9) Further, the blade set 30 includes an elastic sheet 31 and a rubber strip 32. The elastic sheet 31 is disposed under the bottom plate 21. The rubber strip 32 is connected with the elastic sheet 31 and extended on one side of the accessory seat 20. In some embodiments, the blade set 30 includes two rubber strips 32 extended oppositely on two sides of the accessory seat 20.

(10) In detail, the shell seat 11 has an opening 100. The shell seat 11 is formed with a receiving trough 110 at the position of the opening 100 and corresponding to the two side plates 22 of the accessory seat 20. The shell seat 11 is formed with the pressing blocks 12 at corners of the receiving trough 110 (the opening 100). In addition, the accessory seat 20 includes the pivot 201 disposed between the two side plates 22. Each of the two side plates 22 is disposed with two indents 220 at two sides of the pivot 201. The indent 220 may be used for connecting with different driving arms 2 to increase utility.

(11) In some embodiments, the shell seat 11 is formed with multiple fastening sheets 111 on a periphery of the receiving trough 110. The fastening sheets 111 are adjacent to the opening 100. In addition, the two side plates 22 are disposed with multiple fastening holes 221 corresponding to positions of the fastening sheets 111. The fastening sheets 111 are engaged with the fastening holes 221 to make the accessory seat 20 be connected in the fixing seat 10 more firmly.

(12) In detail, the shell seat 11 is formed with multiple support sheets 112 on the bottom of the receiving trough 110. Also, two ends of the bottom plate 21 abut against the support sheets 112. In addition, the support sheets 112 are disposed separately corresponding to the pressing blocks 12 in position. The protrusive sheets 23 are inserted between the support sheets 112 and the pressing blocks 12 as shown in FIG. 3, respectively.

(13) In an embodiment of the disclosure, the shell seat 11 is disposed with a groove 113 on two sides of each support sheet 112 as shown in FIG. 2. Each protrusive sheet 23 is inserted between the groove 113 and the pressing block 12 as shown in FIGS. 2 and 3.

(14) It is noted that a cross-section of the bottom plate 21 is corresponding to a cross-section of the support sheet 112 to be a U-shape as shown in FIG. 6. Thus, the bottom plate 21 and the support sheet 112 may indeed abut against each other to make the both connect more firmly.

(15) It is also noted that when the accessory seat 20 of the disclosure is being assembled in the fixing seat 10, the protrusive sheet 23 on a side of the accessory seat 20 is placed in the pressing block 12 on one side of the shell seat 11 first to be placed in the receiving trough 112, and then the protrusive sheet 23 on the other side of the accessory seat 20 is pressed to be under the pressing block 12 on the other side. As a result, the accessory seat 20 is assembled in the fixing seat 10 by means of interference fit to make the accessory seat 20 be unable to be separated from the fixing seat 10.

(16) While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
