Detailed Description
The following examples are presented to enable those skilled in the art to more fully understand the present invention and are not intended to limit the scope of the present invention.
The automobile wiper protection device shown in figures 1-4 comprises
The windscreen wiper assembly comprises a windscreen wiper body 1, the tail end of the windscreen wiper body 1 is hinged to an automobile, the windscreen wiper body 1 comprises a connecting seat 11, a scraping rod 14 and a wiper blade connected with the scraping rod 14, a bearing is arranged in the connecting seat 11, connecting holes 17 are symmetrically formed in two sides of the tail end of the scraping rod 14, the connecting seat 11 and the scraping rod 14 are riveted in the connecting holes 17 and bearing inner holes through rivets 19 to achieve rotating connection, a metal sleeve 111 is sleeved on the rivets 19, an interference fit is formed between the metal sleeve 111 and the rivets 19 and between the metal sleeve 111 and the bearing, and two ends of the metal sleeve 111 are welded and fixed on the scraping rod 14.
The two outer sides of the scraping rod 14 are provided with the grooves 15 at the connecting holes 17, the grooves 15 are circular, the grooves 15 are matched with the end parts of the two ends of the rivet 19, the inner wall of each groove 15 can have a collision effect on the end part of the rivet 19, and gaps are reserved between the two ends of the rivet 19 and the butting parts of the two sides of the scraping rod 14.
Be connected with elastic component 13 between connecting seat 11 and scraping pole 14, elastic component 13 is extension spring, and extension spring one end is connected in the well rear end of scraping pole 14, and the other end is connected with the connecting rod 12 of rotating the connection on connecting seat 11, and the length of connecting rod 12 is greater than the length of junction to connecting seat 11 front end of connecting rod 12.
To the metal covering 111 that sets up on the rivet 19, metal covering 111 is located between rivet 19 and the bearing, strengthen the holistic anti deformability of rivet 19, the inside rivet 19 of metal covering 111 has also strengthened the anti deformability of metal covering 111 simultaneously, can effectively prevent that rivet 19 and metal covering 111 from taking place deformation, metal covering 111 both ends are connected on scraping the pole 14 simultaneously, when external force makes metal covering 111 take place the deformation trend, scrape 14 both sides of pole and can produce the axial effort that prevents metal covering 111 and take place deformation to metal covering 111, prevent rivet 19 and metal covering 111 more and take place deformation, thereby avoid scraping pole 14 and rotate the inflexible phenomenon of blocking even.
The driving assembly comprises a swinging connecting rod 21, a driving motor 22, a speed reducer 23 and a rotating shaft 24, wherein one end of the swinging connecting rod 21 is hinged below the middle position of the windscreen wiper body 1, a groove 25 for embedding the rotating shaft 24 is formed in the other end of the swinging connecting rod 21, and the rotating shaft 24 is driven to rotate by the matching of the driving motor 22 and the speed reducer 23.
The connection between the swing link 21 and the rotation shaft 24 is: a clamping ball 26 is further installed on a section of the rotating shaft 24 embedded in the swing link 21, the clamping ball 26 is installed on the rotating shaft 24 through a return spring 27, meanwhile, an installation groove for accommodating the return spring 27 and the clamping ball 26 is formed in the rotating shaft 24, the outer side of the clamping ball 26 extends out of the installation groove, and an arc-shaped groove attached to the clamping ball 26 is further formed in the inner wall of the groove of the swing link 21. To setting up reset spring 27, screens ball 26 between swing link 21 and the rotation axis 24, when wiper main part 1 did not block firmly, screens ball 26 has the part to arrange in the arc recess, thereby make rotation axis 24 and swing link 21 carry out synchronous rotation, ensure wiper main part 1 normal work, and when wiper main part 1 blocked firmly, along with driving motor 22's moment of torsion grow, screens ball 26 can break away from in the arc recess, like this, rotation axis 24 still rotates, and wiper main part 1 does not rotate, thereby avoided driving motor 22 because of the phenomenon of the stifled commentaries on classics that wiper main part 1 blocks firmly and arouses, avoided the burning of driving motor 22.
The volume of the clamping ball 26 placed in the mounting groove is larger than that of the clamping ball 26 placed in the arc-shaped groove. Through arranging screens ball 26 in the volume of mounting groove in be greater than the volume of arranging in the arc recess to when convenient card was died at wiper main part 1, screens ball 26 can just break away from in the arc recess under the circumstances as little as possible at the driving motor moment of torsion, reduces the damage to driving motor.
The working principle is as follows: when the wiper main body 1 normally works, the driving motor 22 and the speed reducer 23 are matched together to drive the rotating shaft 24 to rotate, and the clamping balls 26 are clamped in the arc-shaped grooves, so that the rotating shaft 24 rotates while driving the swinging connecting rod 21 to synchronously rotate, and the swinging connecting rod 21 rotates to drive the wiper main body 1 to swing.
When the wiper body 1 is stuck due to self reasons or external factors, the wiper body 1 cannot rotate, and the swing connecting rod 21 cannot move due to the wiper body 1, at the moment, the driving motor 22 and the speed reducer 23 can also drive the rotating shaft 24 to rotate, and when the torque gradually increases, the blocking balls 26 gradually break away from the arc-shaped groove under the influence of the torque acting force, so that the rotating shaft 24 rotates, the phenomenon of rotation blockage of the driving motor 22 is avoided, and the motor is prevented from being burnt.
It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
