Embodiment
Refer to shown in Fig. 1 to 5, scraping blade 2, scraping arm 3 are included according to a kind of wiper 100 of embodiment of the application
And for connecting the joint 1 of the scraping blade 2 of wiper 100 and the wiper 100 of scraping arm 3.
Scraping blade 2 includes the parts such as adhesive tape 21, spoiler 22, installation portion 23.
Joint 1 includes scraping blade connecting portion 12 and scraping arm connecting portion 13.Scraping blade connecting portion 12 and the bodily form of scraping arm connecting portion 13 1
Into.For example, scraping blade connecting portion 12 and scraping arm connecting portion 13 are integrally formed by injection molding process.
Scraping blade connecting portion 12 includes articulated section 120.Articulated section 120 is formed as from the outstanding cylinder of the opposite sides of joint
Shape, two cylindrical coaxials（It is the revolving body around axis X 0 jointly）.Articulated section 120 is used for the installation portion 23 for connecting scraping blade 2,
To enable joint 1 to be pivoted relative to scraping blade 2 around axis X 0.
Scraping arm connecting portion 13 includes the clamping part 132 of receiving space 130 and first.The one side of receiving space 130 has insert port
134, for for scraping arm 3, X1 to be inserted in the first direction.Receiving space 130 is a square inner chamber, and receiving space 130 wraps
Breach 131 is included, breach 131 opens to perpendicular to first direction X1 direction, and in embodiment as shown in Figure 3
Breach 131 connects with insert port 134.
First clamping part 132 has can be to the free degree flexibly swung parallel to the direction of axis X 0, and has and can apply
Add the blocking surface 136 of the power of the direction of insertion towards scraping arm 3.One of ordinary skill in the art knows that the first clamping part 132 exists
Movement locus is in camber line during swing, therefore the first clamping part 132 is not limited to the free degree swung parallel to the direction of axis X 0
One clamping part 132 has parallel to axis X 0 utterly parallel to the movement in the direction of axis X 0 including the first clamping part 132
The movement in the off-axis X0 directions of the mobile component in direction.First clamping part 132 includes through hole 133, and blocking surface 136 is formed at
The trailing flank of through hole 133（In this application, rear side refers to the side of the remote axis X 0 of through hole 133, and front side refers to through hole 133
Close axis X 0 side）.Certainly, one of ordinary skill in the art knows, through hole 133 can also be formed as the knot such as depression
Structure, as long as there is the blocking surface 136 for the power that can apply the direction of insertion towards scraping arm 3.First clamping part 132 is located at joint
The position of 1 remote scraping blade connecting portion 12, and the first clamping part 132 is located at breach 131.
Scraping arm 3 is in the longitudinal parallel to first direction X1 extensions, its near-end（It is not shown）For being connected to driver（Not
Diagram）Output shaft, driver by output shaft export reciprocating rotating move, it is past so as to be drivingly connected to the scraping arm 3 of output shaft
Physical pendulum moves.The distal end of scraping arm 3（Away from output the tip of the axis）With plug division 30.Plug division 30 has parallel to first direction X1
First side 31, be provided with the second clamping part 32 in first side 31.Second clamping part 32 includes protruding from first side 31
Excrescence 33, excrescence 33 has guide surface 34.Guide surface 34 be one relative to 31 inclined face of first side, it is from scraping
Proximally direction gradually rises for the distal end of arm 3（Rise, refers to farther away from first side 31）.Excrescence 33 can pass through joint 1
Breach 131, and can enter in depression or the through hole 133 of the first clamping part 132, and be positioned in.
With that can coordinate the square of receiving space 130, it can insert receiving space 130 for plug division 30.Square collecting is empty
Between 130 scraping arms 3 that are inserted of limitation rotate and moved to perpendicular to first direction X1 direction.When scraping arm 3 is inserted into joint 1
When, moved along the direction of the proximate of scraping arm 3, when scraping arm 3 is removed from joint 1, along the distal end of scraping arm 3 proximally
Move in direction.The design can prevent from mispluging connecing.If according to first side 31 perpendicular to the position of axis X 0 X1 in the first direction
Scraping arm 3 is inserted, the second clamping part 32 is just directed at the breach 131 of receiving space 130, and scraping arm 3 can smoothly insert the receipts of joint 1
Hold space 130；If being inserted according to other positions, the second clamping part 32 is not aligned with the breach 131 of receiving space 130, then scraping arm 3
The receiving space 130 of joint 1 can not be inserted.During inserting receiving space 130 in plug division 30, the first clamping part 132 is first
The guide surface 34 of the second clamping part 32 is touched, second clamping part 32 first promotes the first clamping part under the guiding of guide surface 34
132, to the direction elastic deformation away from first side 31, are further inserted into rear through hole 133 and surmount excrescence 33, the first clamping part
132 discharge elastic deformations and enter through hole 133 to close to the recovery of the direction of first side 31, excrescence 33.Now, to that will scrape
Arm 3 exits again, and blocking surface 136 then applies towards the mechanical resistance of direction of insertion and stops the second clamping part 32 to the opposite of the direction with insertion
Direction movement.
According to the plug division 30 of the joint 1 of the application and scraping arm 3, simple in construction, easy to manufacture, cost are low.Moreover, installation
The operation of scraping arm 3 is also simple, it is only necessary to scraping arm 3 is inserted into receiving space 130 in one direction, in place when immediately by the first buckle
Portion 132 is pinned, you can completes installation.
Above embodiment is merely to illustrate the application, and is not the limitation to the application, relevant technical field
Those of ordinary skill, in the case where not departing from scope of the present application, it can also make a variety of changes and modification, thus it is all etc.
Same technical scheme falls within the category of the application, and the scope of patent protection of the application should be defined by the claims.
