The utility model discloses seesaw formula assembly device (hereinafter for short assembly device 100) of windshield wiper includes: a wiper fixing seat 1, a connecting seat 2 and a control component 3. It should be noted that the assembled wiper body 900 abuts on a surface of an object to be wiped (not shown), such as a glass of a vehicle, so that the assembled wiper body 900 is parallel to the object to be wiped.

The wiper holder 1 is fixed to the wiper body 900 as shown in fig. 2. The windshield wiper fixing seat 1 is transversely erected with a rod 11 and is provided with at least one buckling part 12, in this embodiment, two buckling parts 12 are provided.

The engaging base 2 is detachably assembled to the wiper fixing base 1 as shown in fig. 1 to 4. The present invention is not limited to the structure of the joint base 2, and in the present embodiment, the joint base 2 may include two end panels 201, two side panels 202, a bottom panel 203 and a top panel (not labeled with reference numerals) surrounding each other. The connecting seat 2 has a rod slot 21 from the bottom plate 203 toward the top plate, and the connecting seat 2 has a sliding slot 22 from one end plate 201 toward the other end plate (not labeled with reference numeral). The rod 11 is accommodated in the rod groove 21, and the connecting base 2 can swing in a see-saw manner relative to the wiper fixing base 1 using the rod 11 as a fulcrum. The seesaw type deflection comprises positive deflection and negative deflection.

The adapter 2 may also preferably have a sliding slot 22 formed in the end plate 201, a groove 23 formed in each of the two side plates 202, and a reverse-buckling portion 24 formed in the bottom plate 203, as shown in fig. 1. Wherein, the chute 22 is opened from the end panel 201 to the other end panel; the groove 23 is communicated with the sliding groove 22, the notch of the groove 23 is positioned on the end plate 201, and the groove 23 extends from the end plate 201 to the other end plate direction and forms the groove tail end of the groove 23 at the extending tail end.

The control member 3 is combined with the joint base 2 as shown in fig. 1 to 4, so that the control member 3 can swing together with the joint base 2. Preferably, the control member 3 can be slidably connected in the sliding groove 22; during the sliding movement, the control member 3 is guided by the slide groove 22 to move linearly relative to the adapter 2. The present invention is not limited to the structure of the control member 3, in this embodiment, the control member 3 has at least one buckle 31 (in this embodiment, two buckles 31), and the control member 3 can further have a reverse-buckling elastic arm 32 and a cross-connected pillar 33. Wherein, the reverse-buckling elastic arm 32 has a reverse-buckling body 321; the column 33 has a controlled portion 331, and the column 33 is exposed out of the sliding slot 22. The two buckle bodies 31 are exposed out of the connecting base 2 through the two grooves 23, respectively, so as to be buckled in the buckle portion 12 through the exposed portions.

In order to prevent the control member 3 from easily falling off the engaging seat 2, when the control member 3 is inserted into the sliding slot 22, as shown in fig. 3, the fastening body 321 of the reverse-fastening elastic arm 32 is adapted to be reversed corresponding to the reverse-fastening portion 24, so as to prevent the control member 3 from easily falling off due to reverse-fastening from the sliding slot 22.

It should be noted that, since the buckle portion 12 is a longitudinal groove with an upward opening, and in a state where the engaging seat 2 and the control member 3 are parallel to the wiper holder 1 together, as shown in fig. 9A, the buckle body 31 and the buckle portion 12 are approximately equal in height, it is necessary that the buckle body 31 moves to an upper side of the opening of the buckle portion 12 (see fig. 6) through a seesaw type reverse deflection, the control member 3 moves the buckle body 31 to a position right above the opening of the buckle portion 12 (see fig. 8A) through a linear sliding, and finally the buckle body 31 is buckled in the buckle portion 12 through a reverse direction forward deflection.

As mentioned above, the linear sliding movement of the control member 3 is preferably used to fix the rocker arm 800. To this end, the adapter 2 and the swing arm 800 must be added with some structure, as described in the following three paragraphs.

As shown in fig. 1 and 6, the engaging base 2 may be respectively recessed with two limiting grooves 25 on the outer walls of the two side plates 202, and the limiting grooves 25 include a longitudinal section 251 and a transverse section 252 connected end to form a bent shape.

As shown in fig. 5 and 6, the bottom surface of the swing arm 800 faces upward and is provided with a receiving space 84 and a moving space 85, and the two spaces are separated by a blocking portion 82. Moreover, the inner wall of the rocker arm 800 corresponding to the position of the accommodating space 84 is also provided with a plurality of convex bodies 81; the top surface of the swing arm 800 is further provided with an opening 83 corresponding to the position of the movable space 85.

As shown in fig. 6, 7A and 7B, the rocker arm 800 can be longitudinally sleeved on the connecting seat 2 by the accommodating space 84 (the transverse distance of the accommodating space 84 is greater than the transverse length of the connecting seat 2), so that each protrusion 81 of the rocker arm 800 can smoothly enter the longitudinal section 251 of each limiting groove 25, and at this time, the column 33 of the control member 3 does not block the blocking portion 82. As shown in fig. 8A and 8B, the swing arm 800 is operated to translate transversely (towards left) relative to the connecting base 2, so that each convex body 81 enters each transverse section 252 along the same direction, and each convex body 81 is limited longitudinally by the transverse section 252, so that each convex body 81 can move transversely (towards right) in one direction only and cannot move longitudinally; then, the operation control member 3 slides relative to the engaging seat 2, so that the column 33 moves in the moving space 85 and is stopped at the stopped portion 82 of the swing arm 800, that is, the column 33 will stop the stopped portion 82 in the direction that the swing arm 800 moves towards the right, so that the swing arm 800 is stably fixed on the assembling device 100 of the present invention.

In other embodiments not shown in the drawings, the present invention can omit the design of linear sliding, and the wiper body 900 can be assembled or disassembled from the rocker arm 800 by only performing the aforesaid two-way deflection. For example, as long as the buckle portion 12 is provided with a restriction structure that is difficult to withdraw in a reverse direction after the buckle body 31 is buckled, an external force capable of overcoming the restriction needs to be applied to withdraw the buckle body 31.

Each operation of the present invention is described in detail below.

As shown in fig. 4 and 6, during assembly, the engaging base 2 is operated to swing reversely to be inclined, so that the buckle body 31 moves to the obliquely upper side of the buckle part 12 as shown in fig. 6; as shown in fig. 7A and 7B, the swing arm 800 is sleeved on the connecting base 2, so that the convex body 81 enters the longitudinal section 251, and the controlled portion 331 of the column 33 is exposed or protrudes from the swing arm 800 through the opening 83; as shown in fig. 8A and 8B, the rocker arm 800 is operated to translate left relative to the connecting seat 2 and the control member 3 is operated (via the pushing controlled portion 331) to slide left relative to the connecting seat 2, so that the convex body 81 enters and is limited in the transverse section 252, and the control member 3 not only can stop the column 33 in the right translation direction of the rocker arm 800, but also can move the buckle body 31 to a position right above the buckle portion 12; as shown in fig. 9A and 9B, finally, the fastening body 31 can move downward and be fastened in the fastening portion 12, and the wiper body 900 can be parallel to the object (not shown) to be wiped, as long as the engaging base 2 is operated to deflect in the positive direction and return to the positive direction (i.e. return: the engaging base 2 and the control member 3 are parallel to the wiper fixing base 1 together). In other words, in the normal state, the wiper body 900 is restricted from being held in a state parallel to the object to be wiped due to abutting on the surface of the object to be wiped, and the engaging seat 2 is relatively restricted from being held in this return state, so that it is absolutely impossible to detach in this state; unless the swing arm 800 is operated to bring the wiper body 900 away from the object to be wiped, and then the engaging base 2 is operated to be tilted reversely as shown in fig. 8A, the buckle body 31 can be withdrawn from the buckle portion 12 to facilitate the subsequent detaching operation.

On the contrary, when the disassembly is desired, the reverse operation is only required.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
