Abstract

A windshield wiper connector and windshield wiper connection assembly. The windshield wiper connector comprises a main body, a lodging device and a flexible fastening device. The lodging device is disposed to a rear of the main body to lodge with a barb portion at random angles. One end of the flexile fastening device is connected below a front of the main body while another end is an extending end upwardly extended toward an upper side of the main body. The flexible fastening device leans against a protruding portion. After the lodging device is hooked with the barb portion, the windshield wiper arm is rotated by taking a hooking portion as an axis so that the extending end propped by the protruding portion performs a deformation toward a direction being distant from the protruding portion. When the protruding portion crosses the extending end, the extending end is restored.

Claims

1. A windshield wiper connector comprising:

a main body;

a lodging device, disposed to a rear end of the main body, for mutually lodging a barb portion of a windshield wiper arm; and

a flexible fastening device, one end of the flexible fastening device connected below a front of the main body, another end of the flexible fastening device being an extending end upwardly extended toward an upper side of the main body, and the flexible fastening device being for leaning against a protruding portion of the windshield wiper arm;

wherein after the lodging device is lodged with the barb portion, the windshield wiper arm is rotated by taking a lodging portion of the lodging device as an axis so that the extending end of the flexible fastening device is propped by the protruding portion to firstly perform a deformation toward a direction being distant from the protruding portion, and when the protruding portion crosses the extending end, the extending end is restored from a deformation state to fasten the protruding portion so as to fix the windshield wiper arm on the main body.

2. The windshield wiper connector as recited in claim 1, further comprising a containing portion connecting the front of the main body and forming a containing space, the flexible fastening device located in the containing space.

3. The windshield wiper connector as recited in claim 2, wherein the containing portion is a U-shaped structure.

4. The windshield wiper connector as recited in claim 2, wherein the flexible fastening device comprises a flexible portion and a fastening portion, and one end of the flexible portion is disposed below the front of the main body, another end of the flexible portion is extended toward the upper side of the main body and connected to the fastening portion to become the extending end, and the fastening portion protrudes to the containing space, and the fastening portion comprises a guiding surface for guiding the protruding portion to cross the extending end when the extending end propped by the protruding portion is deformed.

5. The windshield wiper connector as recited in claim 4, wherein the flexible portion and the fastening portion are connected to form a cavity, and when the protruding portion of the windshield wiper arm is approached to the flexible fastening device, the guiding surface is propped by the protruding portion to allow the flexible portion performs the deformation toward the direction being distant from the protruding portion, and when the protruding portion crosses the extending end and falls into the cavity to mutually leaning against each other, the fastening portion is hooked with the protruding portion.

6. The windshield wiper connector as recited in claim 1, wherein the lodging device is a flexible object.

7. The windshield wiper connector as recited in claim 1, wherein the lodging device is connected to two sides of the rear of the main body.

8. The windshield wiper connector as recited in claim 1, wherein the main body is an elongated structure.

9. The windshield wiper connector as recited in claim 1, wherein the barb portion is disposed at two ends of the windshield wiper arm, and the protruding portion is disposed to one end of the windshield wiper arm.

10. A windshield wiper connection assembly comprising:

a windshield wiper connector comprising a main body, two sides of a rear of the main body disposed with a first lodging portion and a second lodging portion, a front of the main body disposed with a flexible fastening body, the flexible fastening body comprising a flexible portion and a fastening portion, the fastening portion further comprising a guiding surface; and

a windshield wiper arm, two sides of the windshield wiper arm having a first barb portion and a second barb portion and corresponding to the first lodging portion and the second lodging portion, one end of the windshield wiper arm having a protruding portion;

wherein the first lodging portion and the second lodging portion are respectively hooked with the first barb portion and the second barb portion, and the windshield wiper arm is rotated by taking a hooking portion as an axis so that the protruding portion is gradually approached to the guiding surface of the fastening portion and mutually leans against each other to allow the flexible portion performing a deformation toward a direction being distant from the protruding portion, and after the protruding portion crosses the fastening portion and is restored from the deformation, the fastening portion is fastened with the protruding portion so as to fix the windshield wiper arm on the main body.

11. The windshield wiper connection assembly as recited in claim 10, further comprising a containing portion connecting the front of the main body and forming a containing space, the flexible fastening body located in the containing space.

12. The windshield wiper connection assembly as recited in claim 11, wherein the containing portion is a U-shaped structure.

13. The windshield wiper connection assembly as recited in claim 11, wherein one end of the flexible portion is disposed below the front of the main body, another end of the flexible portion is extended toward an upper side of the main body and connected to the fastening portion to become an extending end, and the fastening portion protrudes to the containing space, and when the extending end propped by the protruding portion is deformed, the guiding surface is in contact with the protruding portion and guides the protruding portion to cross the extending end.

14. The windshield wiper connection assembly as recited in claim 13, wherein the flexible portion and the fastening portion are connected to form a cavity, and when the protruding portion leans against the guiding surface to allow the flexible portion to perform the deformation toward the direction being distant from the protruding portion, the protruding portion crosses the fastening portion and falls into the cavity from the guiding surface, and the fastening portion is fastened with the protruding portion.

15. The windshield wiper connection assembly as recited in claim 10, wherein the first lodging portion and the second lodging portion are flexible objects.

16. The windshield wiper connection assembly as recited in claim 10, wherein the main body is an elongated structure.
