Description

Technical Field

[0001] This utility model belongs to the field of windshield wiper technology and relates to a connecting mechanism for an automotive windshield wiper. Background Technology

[0002] Windshield wipers are an important component of a car. By installing windshield wipers on the windshield, the windshield can be quickly wiped away rainwater when driving in rainy weather, ensuring the windshield remains clear. The connecting structure is one of the components of the windshield wiper, mainly used for the installation of the windshield wipers.

[0003] Traditional car wiper connection mechanisms mainly use screws for connection. Over time, the screws are prone to rusting. When the connection structure ages, replacement is not an option, affecting the ease of use of the car wiper connection mechanism. To address these issues, we designed a new car wiper connection mechanism. Summary of the Invention

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1-5 As shown, the present invention discloses a connecting mechanism for a car windshield wiper, including a wiper blade fixing seat 1 and a mounting seat 2 for connecting a car rocker arm. A connecting seat 3 is provided between the wiper blade fixing seat 1 and the mounting seat 2. The connecting seat 3 is detachably connected to both the wiper blade fixing seat 1 and the mounting seat 2. An elastic arm 4 is provided on the connecting seat 3. When the connecting seat 3 and the mounting seat 2 are assembled and connected, the elastic arm 4 on the connecting seat 3 and the mounting seat 2 elastically abut against each other. A locking structure is provided between the mounting seat 2 and the elastic arm 4 to prevent the connecting seat 3 and the mounting seat 2 from detaching.

[0023] Specifically, by using the connecting seat 3 to detachably connect the wiper blade fixing seat 1 and the mounting seat 2, instead of the traditional installation using screws, the assembly and disassembly of the car wiper connection mechanism is made easier.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention relates to a connecting mechanism for an automotive windshield wiper, wherein an elastic arm 4 extends outward from one end of a connecting seat 3 and is suspended in mid-air.

[0025] Specifically, the elastic arm 4 is curved in an elephant trunk shape. This design facilitates elastic contact with the mounting base 2 and also allows external forces to be applied to the elastic arm 4, causing it to undergo upward elastic deformation.

[0026] The locking structure includes a locking groove 5 on the elastic arm 4 and a locking protrusion 6 on the mounting base 2. When the connecting base 3 and the mounting base 2 are assembled relative to each other, the locking protrusion 6 on the mounting base 2 and the locking groove 5 on the elastic arm 4 are locked together.

[0027] Specifically, the mounting base 2 and the connecting base 3 are assembled by engaging the locking protrusion 6 with the locking groove 5.

[0028] The elastic arm 4 has protruding edges 7 on both sides of its sidewalls. The slot 5 is located on the bottom surface of the protruding edge 7 and the slot opening of the slot 5 faces downward. The mounting base 2 has an inwardly turned edge 8. The locking protrusion 6 is located on the inwardly turned edge 8. The inwardly turned edge 8 of the mounting base 2 and the protruding edge 7 of the elastic arm 4 are slidably assembled. When the inwardly turned edge 8 slides to the bottom of the protruding edge 7 of the elastic arm 4, the locking protrusion 6 is located in the corresponding slot 5 of the protruding edge 7. The sliding abutment end of the protruding edge 7 of the elastic arm 4 is provided with a guide abutment surface 9.

[0029] Specifically, the guide abutment surface 9 is provided with an arc-shaped surface for guiding and abutting when the inner flange 8 of the mounting base 2 and the convex flange 7 of the elastic arm 4 are slidably assembled; the purpose of this setting is to facilitate the elastic deformation of the elastic arm 4 during sliding assembly.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention relates to a connecting mechanism for a car windshield wiper. The upper surface of the connecting seat 3 is provided with a locking post 10, and the mounting seat 2 is provided with a locking slot 11. When the mounting seat 2 and the connecting seat 3 are slidably assembled, the locking post 10 and the locking slot 11 on the mounting seat 2 are locked in place.

[0031] The fixed base has symmetrically arranged upright plates 12, and a pin 13 passes through between the two upright plates 12. The connecting base 3 is provided with a locking hole 14, and the locking hole 14 of the connecting base 3 and the pin 13 of the fixed base are locked together.

[0032] Specifically, the opening of the locking hole 14 is set as a narrow opening. After the pin 13 is locked in the locking hole 14 through the narrow opening, the fixed seat and the connecting seat 3 are hinged, and the fixed seat and the connecting seat 3 can rotate relative to each other.

[0033] The two upright plates 12 of the fixed base are also provided with insertion holes 15, and the connecting base 3 is also provided with locking positions 16. When the fixed base and the connecting base 3 are assembled, the insertion holes 15 and the locking positions 16 are correspondingly locked. The locking positions 16 of the connecting base 3 are also provided with a mounting structure for connecting the car rocker arm insert shaft 17. The mounting structure includes a locking block 18 and a locking block 29. The locking block 18 is provided with an arc-shaped notch 20, and the locking block 29 is provided with an arc-shaped notch 21. The arc-shaped notch 20 of the locking block 18 and the arc-shaped notch 21 of the locking block 29 form a narrowing.

[0034] Specifically, the purpose of this design is that the arc-shaped notches 20 and 21 on the first and second blocks 18 and 19 are used to hold the car rocker arm with the insert shaft, so that it can be assembled with the car rocker arm with the insert shaft in actual use.

[0035] In specific implementation, when assembling the connection structure, the wiper blade fixing seat 1 and the connecting seat 3 are first installed. The connecting seat 3 is fixed by the locking hole 14 at the bottom and the pin 13 in the middle of the wiper blade fixing seat 1. When the wiper blade fixing seat 1 and the connecting seat 3 are engaged, the locking position 16 at the bottom of the connecting seat 3 is engaged with the insertion hole 15, which facilitates the insertion of the car rocker arm insertion shaft 17. Next, the connection between the connecting seat 3 and the mounting seat 2 is achieved by the locking post 10 at the top of the connecting seat 3 engaging with the locking slot 11 at the top of the mounting seat 2. At the same time, the locking protrusion 6 at the end of the mounting seat 2 engages with the locking grooves 5 on both sides of the elastic arm 4 of the connecting seat 3, thereby realizing the assembly between the connecting seat 3 and the mounting seat 2 and completing the assembly of the wiper connection mechanism.
