This application claims the priority benefit of China application serial no. 202321654244.2, filed on Jun. 28, 2023. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The disclosure relates to a vehicle component, and more particularly to a wiper device.
In recent years, efforts to provide access to sustainable transportation systems that also take into account vulnerable persons such as the elderly and children among traffic participants have been active. In order to achieve the stated purpose, research and development efforts are made to further improve the safety or convenience of transportation through research and development related to visibility. However, in the research and development of visibility, the adapter member of the wiper structure is susceptible to freezing at low-temperature environment, which affects the normal operation and reduces the wiping effect, which is detrimental to the driver's visibility of the environment outside the vehicle. Thus, it is necessary to improve the wiper structure to overcome the above problem.
The disclosure provides a wiper device capable of preventing an adapter member thereof from freezing in a low-temperature environment.
The disclosure provides a wiper device, including: an adapter member; a blade structure, including an element portion and a blade portion, where the element portion has an insertion portion and a holding portion, the insertion portion is inserted into an interior of the adapter member, and the holding portion holds the blade portion below the adapter member; a first cover, covering a gap between the holding portion and the adapter member and attached to the adapter member along a first direction perpendicular to an extending direction of the blade structure; and a second cover, covering the gap and attached to the adapter member along a second direction perpendicular to the extending direction.
Based on the above, in the wiper device of the disclosure, the first cover and the second cover are provided on the adapter member and are configured to cover the gap between the holding portion of the blade structure and the adapter member. Accordingly, snow water in a low-temperature environment may be prevented from intruding into the interior of the adapter member. Thus, the wiper device of the disclosure may prevent the adapter member thereof from freezing in a low-temperature environment.
In order to make the aforementioned features and advantages of the disclosure comprehensible, embodiments accompanied with drawings are described in detail below.
In the embodiment of the disclosure, the wiper device further includes an injection nozzle unit, and the injection nozzle unit is configured to inject a washer liquid and is accommodated between one of the first cover and the second cover and the adapter member.
In the embodiment of the disclosure, a top height of the first cover and a top height of the second cover are identical to or less than a top height of the adapter member.
As mentioned above, in the wiper device 100 of this embodiment, the first cover 140 and the second cover 150 are provided on the adapter member 110 and are configured to cover the gap G between the holding portion 1222 of the blade structure 120 and the adapter member 110. Accordingly, snow water in a low-temperature environment may be prevented from intruding into the interior of the adapter member 110. Thus, the wiper device 100 of this embodiment may prevent the adapter member 110 thereof from freezing in a low-temperature environment.
Referring to
In this embodiment, the top height of the first cover 140 and the top height of the second cover 150 are identical to the top height of the adapter member 110. That is, the top surface S1 of the first cover 140 and the top surface S2 of the second cover 150 are flush with the top surface S3 of the adapter member 110. Accordingly, the top portion of the first cover 140 and the top portion of the second cover 150 are not higher than the top portion of the first cover 140, which is beneficial to minimizing air resistance. In other embodiments, the top height of the first cover 140 and the top height of the second cover 150 may be smaller than the top height of the adapter member 110.
To sum up, in the wiper device of the disclosure, the first cover and the second cover are provided on the adapter member and are configured to cover the gap between the holding portion of the blade structure and the adapter member. Accordingly, snow water in a low-temperature environment may be prevented from intruding into the interior of the adapter member. Thus, the wiper device of the disclosure may prevent the adapter member thereof from freezing in a low-temperature environment.
Finally, it should be noted that the foregoing embodiments are only used to illustrate the technical solutions of the disclosure, but not to limit the disclosure; although the disclosure has been described in detail with reference to the foregoing embodiments, persons of ordinary skill in the art should understand that the technical solutions described in the foregoing embodiments can still be modified, or parts or all of the technical features thereof can be equivalently replaced; however, these modifications or substitutions do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the disclosure.
