This application claims priority under 35 U.S.C. § 119 to patent application no. CN 202110376669.0, filed on Apr. 8, 2021 in China, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to the field of motor vehicle fittings, in particular to a holder for a wiper arm, a wiper assembly and a motor vehicle.
As economies have rapidly developed and major advances have been made in technology, people have been demanding noticeably more in terms of quality of life. Compared with the past era of pedestrians and bicycles, motor vehicles appear to have become an indispensable means of transport in the lives of the people of today. In an era when motor vehicles are ubiquitous, people's demands in relation to motor vehicles are not limited to fuel economy and vehicle comfort; driving safety has also become a primary factor to be considered when purchasing a vehicle.
In terms of driving a motor vehicle, rainy and snowy weather not only cause slippery roads and increased braking distance; vision is the chief problem. When driving in rainy and snowy weather, rain and snow generally stick to the motor vehicle's front windscreen, rear windscreen, side windows and rear view mirrors, seriously affecting the driver's vision, and easily causing misjudgements which in turn cause accidents. Windscreen wipers are an important safety fitting on a motor vehicle, being able to effectively clear rain, snow and dirt from the motor vehicle's windscreen, to give the driver a clear field of view, thus ensuring driving safety. At present, in a wiper arm connection structure in the prior art, a holder for a wiper arm is only suitable for a flat wiper arm, by connecting the holder to an adapter, and then connecting the wiper arm to the holder. In the case of specific types of wiper arm, for example types in which an end of the wiper arm has an arc-shaped installation. groove (Roc-lock 3 series wiper arms), interference easily occurs between the wiper arm and the holder structure during installation, thus preventing smooth
Thus, a new type of holder for a wiper arm is urgently needed.
An object of the present disclosure is to solve or mitigate to a certain degree the technical problem mentioned above.
According to a first aspect of the present disclosure, a holder for a wiper arm is provided, comprising:
Optionally, in the holder as described above, the first locking pin and the second locking pin are located at the same height.
Optionally, in the holder as described above, the range of distances from the first locking pin and the second locking pin to the fixing pin is 2.5-3 mm.
Optionally, in the holder as described above, respective ends of the first locking pin and the second locking pin are each provided with a bevelled guide face.
Optionally, in the holder as described above, the first locking pin and the second locking pin are the same size.
According to a second aspect of the present disclosure, a wiper assembly is provided, comprising the holder described above, the wiper assembly further comprising:
Optionally, in the wiper assembly as described above, two notches arranged side by side are provided in each of the two opposite sidewalls of the body of the holder.
Optionally, in the wiper assembly as described above, the end of the wiper arm is provided with a slot matched to the shape of the fixing pin of the holder.
Optionally, in the wiper assembly as described above, the slot of the wiper arm has an elliptical cross section.
According to a third aspect of the present disclosure, a motor vehicle is provided, comprising the wiper assembly described above.
The content of the present disclosure will become easier to understand with reference to the drawings. Those skilled in the art will readily appreciate that these drawings are merely intended for explanatory purposes, and are not intended to limit the scope of protection of the present disclosure. In addition, similar numerals are used to indicate similar components in the drawings, wherein:
To make the abovementioned object, features and advantages of the present disclosure easier to understand, specific embodiments of the present disclosure are explained in detail below with reference to the drawings. First of all, it must be explained that orientational terms mentioned or possibly mentioned herein, such as up, down, left, right, front, back, inside, outside, top and bottom, are defined in relation to the structures shown in the drawings, and are relative concepts, and might therefore vary with position and state of use. Thus, these or other orientational terms should not be interpreted as being restrictive terms.
In some embodiments of the present disclosure, the first locking pin 130 and the second locking pin 140 are located at the same height, as shown in
In some embodiments of the present disclosure, the range of distances from the first locking pin 130 and the second locking pin 140 to the fixing pin 120 may be designed to be 2.5-3 mm.
In some embodiments of the present disclosure, respective ends of the first locking pin 130 and second locking pin 140 of the holder 100 are each provided with a beveled guide face (see
In some embodiments of the present disclosure, the first locking pin 130 and the second locking pin 140 may be designed to be the same size.
In some embodiments of the present disclosure, two notches 113 arranged side by side are provided in each of the two opposite sidewalls 111, 112 of the body 110 of the holder 100. When an operator removes the holder 100 from the adapter 300, he or she need only press a tab formed between the two notches 113 arranged side by side.
In some embodiments of the present disclosure, the wiper arm 200 is provided with a slot 230 matched to the shape of the fixing pin 120 of the holder 100, thereby making it easier for the end 210 of the wiper arm 200 to pivot around the fixing pin 120.
In some embodiments of the present disclosure, the slot 230 of the wiper arm 200 has a substantially elliptical cross section, as shown in
The processes of assembling and disassembling the adapter 300, the wiper arm 200 and the holder 100 for the wiper arm 200 in the wiper assembly are expounded below with reference to
In the process of installing the holder 100, the holder 100 is first of all plugged onto the adapter 300 fixed to the wiper blade 400 by mating the protrusion 310 with the dovetail slot 114 (see
The present disclosure also provides a motor vehicle. The motor vehicle comprises the wiper assembly described above. The motor vehicle may be various types of vehicles such as a private car, a taxi, a bus, a medium-sized coach or a large coach.
In summary, the holder for a wiper arm according to the present disclosure has a simple, optimized structural design, so that in addition to flat wiper arms, other types of wiper arms (e.g. Roc-lock 3 series wiper arms) can also be fitted to the holder, thereby achieving a good connection result and a good wiping/cleaning effect, and thus effectively extending the service life of the wiper. Thus, it is strongly recommended that this holder for a wiper arm be used in a wiper assembly, and it is recommended that the use of this wiper assembly in motor vehicles be popularized.
A number of specific embodiments have been set out above to expound in detail the holder for a wiper arm, the wiper assembly and the motor vehicle according to the present disclosure. These examples merely serve the purpose of explaining the principles of the present disclosure and embodiments thereof, without restricting the present disclosure. Those skilled in the art could make various changes and improvements without departing from the spirit and scope of the present disclosure. Thus, all equivalent technical solutions should be included in the scope of the present disclosure and are defined by the claims thereof
