The pressure groove 18 is matched with the mounting connector 14.
[0032] In this embodiment, a slot 7 is opened on the left side of the restriction groove 12, and the inner cavity of the slot 7 is rotatably connected with a connecting shaft 9, and the surface of the connecting shaft 9 is fixedly connected with a rotating shaft 8. The top of the right side of the rotating shaft 8 is fixedly connected with a pressing plate 10, both sides of the inner cavity of the pressing block 15 are provided with sliding grooves 23, the inner cavity of the sliding groove 23 is slidably connected with a sliding block 24, and the restricting groove 12 The front side and the rear side of both are provided with a locking groove 22, the side of the sliding block 24 close to the locking groove 22 is fixedly connected with an arc-shaped locking head 16, and the locking groove 22 is connected to the arc-shaped locking head When the locking groove 22 moves upward with the pressing plate 10, the arc surface of the locking groove 22 will squeeze the arc surface of the arc-shaped locking head 16 to shrink inward.
[0033] The sliding block 24 is fixedly connected with a spring 25 on the side away from the locking groove 22, the bottom left side of the pressure plate 10 is fixedly connected with a stopper 11, and the right side of the stopper 11 has an arc-shaped surface. When 10 is closed, the gap between the arc-shaped surface of the stop 11 and the fixing column 13 matches the arc-shaped part of the mounting connector 14.
[0034] In this embodiment, both sides of the fixing frame 1 are fixedly installed with deflectors 2, and the bottoms of the fixing frame 1 and the deflectors 2 are both provided with installation grooves 5, and the inner cavity of the installation groove 5 is fixed. A buffer rigid elastic sheet 6 is connected, and the bottom of the buffer rigid elastic sheet 6 is fixedly connected with a scraper.
[0035] In this embodiment, the bottom of the scraper 3 penetrates the mounting groove 5, and the material of the scraper 3 is rubber.
[0036] In this embodiment, a toggle groove 17 is opened on the right side of the pressure block 15.
[0037] A method for disassembling a detachable car wiper, the steps are as follows:
[0038] S1: Insert a finger into the inner cavity of the toggle groove 17, and then forcefully pull the pressure block 15 upwards. The pulling force can be about 10N-30N. The pressure block 15 drives the pressure plate 10 on the top to move, so that the pressure plate 10 is connected to the shaft 9 The shaft rotates counterclockwise, and the arc-shaped locking heads 16 on both sides of the pressure block 15 are stressed. The arc-shaped locking heads 16 slide toward the inner cavity of the sliding groove 23 under the action of the inner wall of the clamping groove 22 to lock the arc The head 16 pushes the sliding block 24 to slide toward the inner cavity of the sliding groove 23, and the sliding block 24 compresses the spring 25 at the same time, until the arc-shaped locking head 16 is completely retracted into the inner cavity of the sliding groove 23, the pressure plate 10 can be opened by the pressure block 15 , After opening, the pressure plate 10 drives the stop 11 to turn up, so that the stop 11 is away from the installation connector 14;
[0039] S2: The user grips the right end of the mounting connector 14, and then forcefully inserts the mounting connector 14 to the left side of the limiting groove 12 until the mounting connector 14 reaches the left end of the inner cavity of the limiting groove 12 and the left side wall of the limiting groove 12 Contact, and then pull up the right end of the installation connector 14 to make the left side of the bottom of the installation connector 14 sink into the cavity of the escape slot 21, continue to pull the right end of the installation connector 14, the pulling force is 10N-30N, install the connector The bottom of the left side of 14 squeezes the limiting elastic member 20 to deform the limiting elastic member 20. When a suitable deformation amount is reached, the distance between the fixed column 13 and the limiting elastic member 20 is greater than the width of the mounting connector 14. According to different implementations or models, the spacing can be 20-40 cm, and then pull the mounting connector 14 to make the mounting connector 14 slide out of the gap between the fixed column 13 and the limit elastic member 20 to complete the disassembly;
[0040] S3: Take out the new wiper, then open the pressure plate 10 of the new wiper with the same operation as S1;
[0041] S4: Insert the mounting connector 14 in S3 into the gap between the fixed post 13 and the escape groove 21 from the upper right of the restricting groove 12 at an inclination angle of 30 degrees, and then use force to make the restricting elastic member 20 elastically deform to make The distance between the fixed post 13 and the limiting elastic member 20 is greater than the width of the mounting connector 14, and the distance is 20-40cm. Then insert the mounting connector 14 into the left side of the inner cavity of the limiting groove 12, and then pull the mounting connector to the right 14. Sleeve the U-shaped groove of the mounting connector 14 on the surface of the fixed column 13;
[0042] S5: Then turn the opened pressing plate 10 counterclockwise with the connecting shaft 9 as the axis. When the two sides of the arc-shaped locking head 16 contact the two side walls of the restricting groove 12, they are squeezed by the two side walls of the restricting groove 12 Press and slide into the inner cavity of the sliding groove 23, continue to press down the pressure plate 10, the pressure is 10N, until the bottom of the pressure block 15 contacts the mounting connector 14, at this time the arc-shaped locking head 16 is located at the opening of the slot 22, The spring 25 is reset, and the spring 25 pushes the arc-shaped locking head 16 into the inner cavity of the slot 22 through the sliding block 24 to complete the installation;
[0043] S6: After installation, drive the wiper controller of the car to check the stability of the installation.
[0044] After the installation is completed, the automobile can drive the actuator to drive the installation connector 14 to move back and forth at a certain frequency to control the wiper 3 to clean the windshield of the automobile.
[0045] It can be seen from the embodiments of the present application that when in use, the pressure plate 10 is pulled upwards, and then the mounting connector 14 is pushed to the left side of the inner cavity of the restricting groove 12, and then the mounting connector 14 is rotated to make the mounting connector 14 appear constant After the angle of inclination, the limit elastic member 20 can be squeezed to release the fixed connection block 4 from the surface of the mounting connector 14 to complete the disassembly. The disassembly process is simple and convenient, which greatly improves the convenience of disassembly. At the same time, the stop 11 at the bottom of the pressure plate 10 It can avoid the situation that the mounting connector 14 is shaking left and right in the inner cavity of the restricting groove 12 after installation. The pressure block 15 and the pressure plate 10 can clamp the mounting connector 14 in the inner cavity of the restricting groove 12 to ensure the stability of the mounting connector 14 Be improved.
