Abstract
The invention relates to an automobile windscreen wiper arm. The automobile windscreen wiper arm comprises a pivot head, a first wiping frame and a second wiping frame, wherein two ends of the first wiping frame are connected with the pivot head and the second wiping frame respectively, and the tensile strength of the first wiping frame is larger than that of the second wiping frame. Preferably, the radial length of the first wiping frame is larger than that of the second wiping frame. More preferably, the first wiping frame is sleeved with a reinforcement pipe. According to the automobile windscreen wiper arm, the wiping capacity of the whole windscreen wiper arm is realized by only increasing the strength of the first wiping frame, so that the wiping capacity is improved while the weight of the windscreen wiper arm is almost not increased.
Description
Technical field
The present invention relates to a kind of vehicle wiper, particularly relate to a kind of automobile wiper arm.
Background technology
Wiper arm is one of safety device on automobile, is mainly used in removing the obstacles such as sleet on glass for vehicle window and dust, to guarantee traffic safety.In order to increase wiper quality and the wiper ability of wiper arm, often adopt the better material of intensity to manufacture wiper arm.May increase the overall weight of wiper arm like this, also increase the difficulty of wiper.
Summary of the invention
The object of the invention is, for above-mentioned the deficiencies in the prior art, provides a kind of automobile wiper arm, and this wiper arm only increases by the first intensity of scraping frame and just strengthened wiper quality.
For achieving the above object, the technical solution used in the present invention is as follows.
, comprising that pivot connector, first scrapes frame and second and scrape frame, the described first two ends of scraping frame are scraped frame with pivot connector and second respectively and are connected, and described the first tensile strength of scraping frame is greater than the described second tensile strength of scraping frame.
Further, described the first radical length of scraping frame is greater than the described second radical length of scraping frame.
Further, also comprise reinforced pipe, one end of described reinforced pipe is connected on described pivot connector, and its other end is connected to described first and scrapes on frame.
Further, also comprise reinforced pipe, described reinforced pipe is sleeved on described first and scrapes on frame.
The invention has the beneficial effects as follows: automobile wiper arm of the present invention, only increase the wiper ability that the first tensile strength of scraping frame is realized whole wiper arm, so just increase the weight of wiper arm hardly, reached equally the effect that improves wiper ability.
Accompanying drawing explanation
Fig. 1 is the structural representation of the first embodiment of automobile wiper arm of the present invention.
Fig. 2 is the structural representation of the second embodiment of automobile wiper arm of the present invention.
In figure, 1-pivot connector, 2-first scrapes frame, and 3-second scrapes frame, 4-reinforced pipe.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is the structural representation of the first embodiment of automobile wiper arm of the present invention, as shown in Figure 1, the automobile wiper arm of this embodiment comprises that pivot connector 1, first scrapes frame 2 and second and scrape frame 3, the first two ends of scraping frame 2 are scraped frame 3 with pivot connector 1 and second respectively and are connected, and pivot connector 1 is connected on automobile.For strengthening the wiper ability of wiper arm, according to wiper arm and automobile window glass interaction principle, first scrapes frame 2 for main force part, can only increase by the first tensile strength of scraping frame 2 and realize the wiper ability of whole wiper arm, therefore can scrape the high-tensile material of frame 2 use by first and make.
As the improvement of embodiment 1, in the situation that the material of wiper arm is constant, to the first size overstriking of scraping frame 2, the first radical length of scraping frame 2 is greater than the second radical length of scraping frame 3.
Fig. 2 is the structural representation of the second embodiment of automobile wiper arm of the present invention, as shown in Figure 2, the improvements of embodiment 2 are to increase reinforced pipe 4 under the material of wiper arm and the prerequisite of size constancy, one end of reinforced pipe 4 can be connected on pivot connector 1, and its other end is connected to first and scrapes on frame 2.As other, select, reinforced pipe 4 also can be sleeved on first and scrape on frame 2.
Automobile wiper arm of the present invention, only increases the wiper ability that the first tensile strength of scraping frame 2 is realized whole wiper arm, so just increases the weight of wiper arm hardly, has reached equally the effect that improves wiper ability.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of the claims in the present invention.
Claims (4)
