However, when a foreign object falls (such as a branch, etc.), the second swing rod is hit, and irreversible damage is caused to the second swing rod and the wiper blade, so that property loss of a user is caused.
In view of the above technical problems, embodiments of the present disclosure provide a wiper capable of avoiding being broken by falling foreign objects. Next, an implementation of the wiper blade will be exemplarily described.
As shown in fig. 1 to 3, the wiper blade includes a base 1, a driving block 2, a first swing link 3, a driving frame assembly 4, a second swing link 5, and a supporting plate assembly 6. The transmission block 2 is rotatably connected with the base 1, and the transmission block 2 is axially provided with a first groove 21 and a second groove 22, and the first groove 21 is close to the windshield relative to the second groove 22. The first end 301 of the first swing rod 3 is provided with a containing cavity 30, and the containing cavity 30 is sleeved with the transmission block 2 and is in sliding connection with the transmission block 2 along the axial direction. The first end 301 has a limiting protrusion assembly 31 inside, and the limiting protrusion assembly 31 extends into the first recess 21 or the second recess 22. The transmission frame assembly 4 is at least partially positioned in the accommodating cavity 30, and the transmission frame assembly 4 is used for driving the limit protrusion assembly 31 to stretch and retract along the radial direction of the transmission block 2. The second swing rod 5 is rotatably connected with the second end 302 of the first swing rod 3, and the second swing rod 5 is used for connecting with a windscreen wiper. The support plate assembly 6 is slidably connected with the first swing rod 3, and is located on one side of the first swing rod 3, which is close to the windshield. The support plate assembly 6 is configured to avoid the second swing link 5 when the limit bump assembly 31 is positioned in the first recess 21. When the limit projection assembly 31 is positioned in the second groove 22, the second swing rod 5 is supported.
The base 1 comprises a mounting seat 11, a driving rod 12 and a supporting seat 13. The mount pad 11 is installed in the inside of car, and the both ends of actuating lever 12 are connected with mount pad 11, supporting seat 13 respectively, and actuating lever 12 and mount pad 11 rotate to be connected for drive first pendulum rod 3 rotates. The first swing rod 3 is located at one side of the supporting seat 13 away from the mounting seat 11.
The rotation axis between the second swing link 5 and the second end 302 of the first swing link 3 is perpendicular to the rotation axis between the first swing link 3 and the base 1.
According to the technical scheme provided by the embodiment of the disclosure, when the second swing rod 5 is required to be separated from the windshield of the automobile, the transmission frame assembly 4 is pushed, and the limiting protrusion assembly 31 is moved out of the first groove 21. The first swing rod 3 is pulled until the limit projection assembly 31 extends into the second groove 22, so that the first swing rod 3 is separated from the automobile windshield. The supporting plate component 6 is used for supporting the joint of the first swing rod 3 and the second swing rod 5, so that the second swing rod 5 can be separated from the automobile windshield under the driving of the first swing rod 3 and the supporting plate component 6. In this way, the second swing rod 5 is separated from the windshield of the automobile, still keeps parallel with the windshield, is not vertically upward, and can be supported by the supporting plate assembly 6, so that the second swing rod is not easily damaged by falling foreign matters.
In some examples, as shown in fig. 3-5, limit bump assembly 31 includes a resilient member 311, a limit bump 312, and a bump 313. The inner wall of the accommodating cavity 30 is provided with a chute 303, and a limiting block 312 is in sliding connection with the chute 303. The two ends of the elastic piece 311 are respectively connected with the bottom of the chute 303 and the limiting block 312, and the protrusion 313 is positioned on the side wall of the limiting block 312. The transmission frame assembly 4 comprises a transmission frame 41, a button 42 and a pressing block 43, wherein two ends of the transmission frame 41 are respectively connected with the button 42 and the pressing block 43, the first end 301 is provided with a through hole 3010, and the button 42 extends out of the through hole 3010. When the button 42 is pressed, the pressing block 43 drives the stopper 312 to move out of the first groove 21 or the second groove 22 through the protrusion 313. When the button 42 is released, the elastic member 311 drives the stopper 312 to extend into the first groove 21 or the second groove 22.
When it is desired to separate the first swing link 3 from the windshield, the button 42 is pressed so that the transmission frame 41 and the pressing block 43 move in a direction approaching the base 1. During the movement of the press block 43, the protrusion 313 is gradually pressed so that the protrusion 313 moves in a direction away from the transmission block 2. Since the protrusion 313 is connected to the side of the stopper 312, the protrusion 313 drives the stopper 312 to move out of the first groove 21, and the elastic member 311 is compressed in the chute 303. Then, the first swing link 3 is pulled outward, and the button 42 is released. In the process of pulling the first swing rod 3, the limiting block 312 abuts against the outer wall of the transmission block 2, and the elastic piece 311 is always in a compressed state. When the limiting block 312 of the first swing rod 3 moves to the second groove 22, the elastic piece 311 extends out of the sliding groove 303 due to the fact that the outer wall of the transmission block 2 is not extruded, so that the limiting block 312 extends into the second groove 22.
When the first swing link 3 needs to be separated from the windshield, the operation is similar to the above operation, and thus, a description thereof will be omitted.
In some examples, the stopper 312 has one protrusion 313 on both sides. Correspondingly, the transmission frame assembly 4 has at least two pressing blocks 43 for pressing the protrusions 313. In this way, the stress of the limiting block 312 can be more uniform, so that the limiting block 312 can be smoothly moved out of the first groove 21 or the second groove 22.
Illustratively, as shown in fig. 5, the protrusion 313 has a cylindrical shape, and an axis of the protrusion 313 is perpendicular to the expansion and contraction direction of the elastic member 311.
Of course, in other examples, the protrusion 313 may also be rectangular, and the shape and size of the protrusion 313 are not particularly limited in the embodiments of the present disclosure.
Illustratively, the resilient member 311 is a spring.
In other examples, the elastic member 311 may be a flexible rod that can be stretched, and the embodiment of the present disclosure does not specifically limit the elastic member 311.
In some examples, as shown in fig. 3 and 4, the drive rack 41 includes a circular ring 411 and a plurality of connecting rods 412. The ring 411 is sleeved with the transmission block 2, the plurality of connecting rods 412 are uniformly distributed along the circumferential direction of the transmission block 2, two ends of each connecting rod 412 are respectively connected with the ring 411 and the button 42, and the pressing block 43 is fixed on one side, deviating from the connecting rods 412, of the ring 411.
The whole transmission frame 41 is hollow structure, so that the whole weight of the transmission frame 41 is relatively low, and the transmission frame 41 can be reset smoothly after a user releases the button 42.
As shown in fig. 3 and 4, the connecting rod 412 includes a first rod 4121 and a second rod 4122, and the first rod 4121 and the second rod 4122 are connected and arranged in a bent manner. The end of the first rod 4121 is connected to the circular ring 411, and the end of the second rod 4122 is connected to the button 42.
In some examples, the end of the receiving cavity 30 remote from the base 1 has a first magnet. The end of the transmission frame component 4 far away from the base 1 is provided with a second magnet, and the first magnet and the second magnet are mutually attracted. Thus, when the user no longer presses the carrier assembly 4, the carrier assembly 4 moves in a direction approaching the inner wall of the first end 301 under the magnetic force of the first magnet, thereby resetting the carrier assembly 4. Wherein the second magnet may be located at the second rod body 4122 of the connecting rod 412.
In some examples, the base 1 has a third magnet on the side close to the first swing link 3. The first end 301 of the first swing rod 3 is provided with a fourth magnet near one side of the base 1, and the third magnet and the fourth magnet are mutually attracted. The third magnet is located on the side of the support base 13 remote from the mounting base 11. When the spacing protruding component 31 is located the first recess 21, first end 301 and supporting seat 13 laminating have stronger connecting force under the magnetic force effect of third magnet and fourth magnet between first end 301 and the supporting seat 13, and then make first pendulum rod 3 and base 1 have higher joint strength to improve the stability after first pendulum rod 3 and base 1 are connected.
When the first swing rod 3 is separated from the windshield, the supporting plate assembly 6 supports the connection part of the second end 302 of the first swing rod 3 and the second swing rod 5, and prevents the second swing rod 5 from rotating in the direction approaching the windshield. Next, an exemplary implementation of the support plate assembly 6 will be described.
In some examples, as shown in fig. 6-8, the support plate assembly 6 includes a drive 61 and a support plate 62. The driving device 61 is used for driving the supporting plate 62 to slide along the length direction of the first swing rod 3. When the first swing link 3 moves in a direction away from the windshield, the driving device 61 drives the support plate 62 to slide in a direction away from the first end 301 of the first swing link 3. When the first swing link 3 moves in a direction approaching the windshield, the driving device 61 drives the support plate 62 to slide in a direction approaching the first end 301 of the first swing link 3.
Next, an implementation of the driving device 61 will be exemplarily described.
In some examples, as shown in fig. 8 and 9, the drive device 61 includes a first gear 611, a second gear 612, and a drive chain 613, the first gear 611 and the second gear 612 being drivingly connected by the drive chain 613. The first gear 611 is rotatably connected to the first end 301, and the driving block 2 has a first serration structure 23, and the first gear 611 is meshed with the first serration structure 23. The second gear 612 is rotatably coupled to the second end 302, and the support plate 62 has a second saw tooth structure 620, the second saw tooth structure 620 being in engagement with the second gear 612.
When the first swing link 3 moves in a direction away from the windshield, the first swing link 3 moves in a direction away from the base 1 and drives the first gear 611 to move. Since the first gear 611 is engaged with the first serration structure 23, the first gear 611 rotates. Meanwhile, the first gear 611 drives the second gear 612 to rotate through the transmission chain 613. Then, the second gear 612 pushes the support plate 62 to move through the second saw tooth structure 620, so that the support plate 62 moves to the connection of the first swing link 3 and the second swing link 5.
Correspondingly, when the first swing link 3 moves in the direction approaching the windshield, the first swing link 3 moves in the direction approaching the base 1 and drives the first gear 611 to move. Since the first gear 611 is engaged with the first serration structure 23, the first gear 611 rotates. Meanwhile, the first gear 611 drives the second gear 612 to rotate through the transmission chain 613. Then, the second gear 612 pushes the support plate 62 to move through the second saw tooth structure 620, so that the support plate 62 no longer supports the second swing link 5.
Of course, in other examples, the support plate assembly 6 may not include the drive device 61 and the support plate 62 may be manually moved by the user.
In some examples, as shown in fig. 3 and 8, the second end 302 of the first swing link 3 has a slide bar 32, the slide bar 32 is parallel to the length direction of the first swing link 3, and the support plate 62 is looped around the slide bar 32 and slidably connected to the slide bar 32. The side of the second end 302 of the first pendulum rod 3 facing the base 1 may have a recess in which the slide bar 32 is fixed.
In some examples, as shown in fig. 8, the support plate 62 includes a first plate body 621 and two second plate bodies 622. The second plate 622 is connected to one side of the first plate 621, which is close to the first swing link 3, and the length direction of the second plate 622 is the same as the length direction of the first swing link 3, and the length direction of the first plate 621 is perpendicular to the length direction of the second plate 622. In this way, the length of the support plate 62 can be made longer and larger than the moving stroke of the support plate 62. In this way, when the first swing link 3 is separated from the windshield, it can be ensured that the support plate 62 can support the connection between the first swing link 3 and the second swing link 5.
Next, a process of moving the first swing link 3 will be exemplarily described.
When the first swing link 3 is pulled outward, the button 42 is first pressed so that the pressing block 43 presses the protrusion 313, thereby removing the stopper 312 from the first groove 21. Then, the first swing link 3 is pulled outward while releasing the button 42, so that the driving frame assembly 4 moves in a direction approaching the inner wall of the first end 301 under the magnetic force of the first magnet, thereby resetting the driving frame assembly 4. In the process of pulling the first swing rod 3 outwards, the first gear 611 drives the second gear 612 to rotate through the transmission chain 613. At the same time, the second gear 612 pushes the support plate 62 to move in a direction away from the first end 301 of the first swing link 3 through the second saw tooth structure 620 on the support plate 62. When the limiting block 312 of the first swing rod 3 extends into the second groove 22, the first swing rod 3 is fixed, and meanwhile the supporting plate 62 moves to the joint of the first swing rod 3 and the second swing rod 5.
When the first swing link 3 is pushed inward, the button 42 is first pressed so that the pressing block 43 presses the protrusion 313, thereby removing the stopper 312 from the second groove 22. Then, the first swing link 3 is pushed inward while releasing the button 42, so that the transmission frame assembly 4 moves in a direction approaching the inner wall of the first end 301 under the magnetic force of the first magnet, thereby resetting the transmission frame assembly 4. In the process of pushing the first swing rod 3 inwards, the first gear 611 drives the second gear 612 to rotate through the transmission chain 613. At the same time, the second gear 612 pushes the support plate 62 to move in a direction approaching the first end 301 of the first swing link 3 through the second saw tooth structure 620 on the support plate 62. When the limiting block 312 of the first swing rod 3 extends into the second groove 22, the first swing rod 3 is fixed, and meanwhile the supporting plate 62 moves to the first swing rod 3 and is only attached to the first swing rod 3.
The foregoing description of the preferred embodiments of the present disclosure is provided for the purpose of illustration only, and is not intended to limit the disclosure to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, alternatives, and alternatives falling within the spirit and scope of the disclosure.
