Description

Technical Field

[0001] The utility model relates to the field of automotive parts, and particularly relates to a wiper sheath. Background Art

[0002] A wiper sheath is a cleaning device installed on an automotive wiper for cleaning the automotive glass. It closely adheres to the automotive glass and swings back and forth to remove rainwater or dust. However, when cleaning dust, the wiper needs to provide appropriate water supply, reduce the friction coefficient, and clean the glass while closely adhering to the glass.

[0003] CN 205186102 U discloses a wiper sheath with a single-row water spraying function, which includes a "human"-shaped convex platform. A cavity is provided inside the convex platform. One vertical surface of the convex platform is the leeward surface, and a plurality of water spraying holes are provided on the leeward surface of the convex platform. A water pipe is provided inside the cavity of the convex platform, and the water pipe is connected to the automotive water tank. This wiper sheath needs to additionally add a water spraying pipe inside the convex platform. Although it provides the water supply function during dust cleaning, this water pipe reduces the deformation ability of the convex platform, and further reduces the fitting ability of the wiper sheath with the arc-shaped glass surface. The wiper sheath needs to be appropriately deformed to enable the sheath to closely adhere to the glass surface. Otherwise, it will cause uneven contact between the wiper blade and the glass, resulting in cleaning dead angles. Summary of the Utility Model

[0004] The present application of the utility model provides a wiper sheath. When installed on the wiper, the water spraying holes of this wiper sheath provide the function of water supply for dust cleaning. This wiper sheath simultaneously increases the deformation ability of the wiper sheath by optimizing the structure, and can well adhere to the automotive glass under a lower pressure.

[0005] The utility model in the first aspect provides a wiper sheath, which includes a wiper sheath body. The wiper sheath body includes a first body part and a second body part. A rib is also connected to the connection point M of the first body part and the second body part;

[0006] Along the direction away from the connection point, the first body part includes an extension section, a curling section, and a U-shaped section connected in sequence. The second body part includes a curling section and a U-shaped section connected in sequence.

[0007] One end of the curling section of the first body part is connected to the extension section, and the other end curls during the extension process and is connected to itself or the extension section again, so that the curling section encloses a water guiding space.

[0008] One end of the curling section of the second body part is connected to the connection point M, and the other end curls during the extension process and is connected to itself again, so that the curling section encloses a water guiding space.

[0009] At least one surface of the curling section is provided with through holes, and the through holes communicate the water guiding space with the external environment;

[0010] The U-shaped section is connected to the curled section. When the wiper sheath body is installed on the vehicle wiper, the U-shaped section extends into the wiper skeleton from the opening.

[0011] In an optional embodiment of the first aspect of the present invention, the water guiding space is connected to the water tank. When in the first state, the curled section deforms, and then the water guiding space is squeezed, promoting the opening degree of the through hole, and the liquid in the water tank is sprayed onto the glass from the through hole.

[0012] In an optional embodiment of the first aspect of the wiper sheath of the present invention, the rib extends towards the end away from the connection point M and bends during the extension process.

[0013] In an optional embodiment of the first aspect of the wiper sheath of the present invention, only one surface of the curled section is provided with a through hole, and the rib extends towards the end away from the connection point M and bends in a direction away from the through hole during the extension process.

[0014] When the bent rib presses against the automobile glass, the relative contact area is larger. When the rib fits onto the automobile glass, it can better clean the cleaning water ejected from the through hole and better clean the automobile glass surface under the same pressure.

[0015] In an optional embodiment of the first aspect of the present invention, the rib extends towards the end away from the connection point M, and during the extension process, the thickness of the rib decreases.

[0016] In this way, the rib can generate a larger bending angle when fitting onto the glass surface.

[0017] In an optional embodiment of the first aspect of the present invention, the arc-shaped outer surfaces of the U-shaped section and the curled section are connected at the tangent point.

[0018] In an optional embodiment of the first aspect of the present invention, the openings of the U-shaped sections of the first body portion and the second body portion are arranged opposite to each other.

[0019] The two U-shaped section openings are arranged opposite to each other, facilitating the wiper strip skeleton to extend into the two U-shaped section openings and facilitating the installation of the wiper sheath on the wiper.

[0020] In an optional embodiment of the first aspect of the present invention, the U-shaped section is divided into a side edge and a bottom section. The side edge is provided with triangular convex teeth. When the wiper skeleton extends into the U-shaped section, the wiper skeleton abuts against the bottom section, and the side edge presses against the wiper skeleton.

[0021] The arrangement of the triangular convex teeth increases the friction between the wiper skeleton and the wiper sheath, preventing relative sliding between the wiper sheath and the wiper skeleton after installation.

[0022] In an alternative embodiment of the first aspect of the present utility model, when the U-shaped section extends into the wiper frame from the opening, an elastic space is formed between the wiper sheath body and the wiper frame;

[0023] In the first state, when the rib presses against the glass and the wiper sheath moves relative to the glass, the wiper sheath body deforms and the elastic space shrinks, promoting the fitting of the wiper sheath to the glass.

[0024] In a specific embodiment of the first aspect of the present utility model, the thickness of the extension section gradually increases from the connection point M towards the curling section.

[0025] In an alternative embodiment of the first aspect of the present utility model, during the extension process starting from the connection point M, the extension section bends in a direction away from the rib to form an arc surface.

[0026] The different settings of the thickness of the extension section increase the deformation amount of the elastic space when being squeezed, and the arc surface setting increases the resilience ability of the extension section.

[0027] In an alternative embodiment of the first aspect of the present utility model, the plurality of through holes are distributed along the long side direction of the wiper sheath body.

[0028] In an alternative embodiment of the first aspect of the present utility model, the distances between the plurality of through holes are the same. In the first state, the plurality of through holes spray cleaning water onto the vehicle glass for uniformly cleaning the glass.

[0029] The plurality of through holes replace the traditional vehicle wiper that sprays water from the engine cover, and the functional water spraying is more balanced.

[0030] In an alternative embodiment of the first aspect of the present utility model, the wiper sheath body is integrally formed.

[0031] The second aspect of the present invention provides a wiper equipped with the wiper sheath of the first aspect.

[0032] Advantages of the present utility model:

[0033] The water supply pipe of the present utility model is integrally designed with the wiper sleeve, and the manufacturing process is simple. After the wiper sleeve body is integrally formed, the water supply pipe is not additionally added in the elastic space. Instead, by evenly arranging through holes along the long side of the wiper body, the function of water spraying is more balanced, replacing the traditional way of water spraying from the engine cover of the car wiper. The wiper sleeve of this application adopts the structures of an extension section, a curling section, and a U-shaped section, and different settings of the convex ribs, the bending direction, and the thickness of the extension section, increasing the deformation amount of the elastic space when being squeezed, making the convex ribs better fit the glass surface. In some optional embodiments, the resilience ability of the extension section is increased. In some optional ways, triangular convex teeth are installed on the U-shaped section, increasing the friction between the wiper skeleton and the wiper sheath, so as to prevent relative sliding between the wiper sheath and the wiper skeleton after installation.

These drawings and text descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0040] The application of the present utility model provides a wiper sheath, including a water spraying hole for providing a dust cleaning function for the wiper sleeve, and at the same time, by optimizing the structure, the deformation ability of the wiper is increased, so that the convex rib 13 can fit the automotive glass well, increasing the cleaning ability and reducing the noise during use.

[0041] The technical solutions of this application and how the technical solutions of this application solve the above technical problems will be described in detail below with specific embodiments. These several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will be described below with reference to the drawings.

[0042] In the first aspect of the present utility model provided by the present application, a wiper sheath is proposed, which includes a wiper sheath body 1. The wiper sheath body 1 includes a first body part 11 and a second body part 12, and a rib 13 is also connected to the connection point M of the first body part 11 and the second body part 12;

[0043] Along the direction away from the connection point, the first body part 11 includes an extension section 111, a curling section 112 and a U-shaped section 113 connected in sequence. The second body part 12 includes a curling section 112 and a U-shaped section 113 connected in sequence.

[0044] One end of the curling section 112 of the first body part 11 is connected to the extension section 111, and the other end curls during the extension process and is connected to itself or the extension section 111 again, so that the curling section 112 of the first body part 11 encloses a water guiding space 1122.

[0045] One end of the curling section 112 of the second body part 12 is connected to the connection point M, and the other end curls during the extension process and is connected to itself again, so that the curling section 112 of the second body part 12 encloses a water guiding space 1122.

[0046] At least one of the surfaces of the curling section 112 is provided with through holes 1121, and the through holes 1121 communicate the water guiding space 1122 with the external environment;

[0047] The U-shaped section 113 is connected to the curling section 112. When the wiper sheath body 1 is installed on the vehicle wiper, the U-shaped section 113 extends into the wiper frame 14 from the opening.

[0048] When the U-shaped opening extends into the wiper frame 14, an elastic space 15 is formed between the wiper sheath body 1 and the wiper frame 14;

[0049] In the first state, when the rib 13 presses against the glass and the wiper sheath moves relative to the glass, the wiper sheath body 1 deforms, and the elastic space 15 shrinks, thereby making the rib 13 fit more closely against the glass.

[0050] As an optional implementation manner, the extension section 111, the curling section 112 and the U-shaped section 113 are integrally formed, which is convenient for mechanical production.

[0051] Exemplarily, with reference to Figures 1 to 3 As shown, the connection point is marked as M, the first body part 11 and the second body part 12, and the first body part 11 and the second body part 12 are connected to the rib 13 at point M;

[0052] The first main body 11 includes an extension section 111, a curled section 112, and a U-shaped section 113 that are connected in sequence. The second main body 12 includes a curled section 112 and a U-shaped section 113 that are connected in sequence. The first main body 11 and the second main body 12 are connected at point M. The extension section 111 of the first main body 11 extends in the X direction.

[0053] In some alternative embodiments, the extension section 111 bends during its extension in the X direction, and the bending direction is away from the surface where the rib 13 is located.

[0054] In some alternative embodiments, the thickness of the extension section 111 of the first main body 11 gradually increases from the connection point M towards the curled section 112 of the first main body 11.

[0055] In some alternative embodiments, during the extension of the extension section 111 starting from the connection point M, it bends in a direction away from the rib 13 to form an arc surface.

[0056] Optionally, the different settings of the thickness of the extension section 111 increase the deformation amount of the elastic space 15 under the same material cost when being squeezed. The arc surface setting increases the resilience ability of the extension section 111.

[0057] In some alternative embodiments, the water guiding space 1122 is connected to the water tank. When in the first state, the curled section 112 deforms, and then the water guiding space 1122 is squeezed, increasing the opening degree of the through holes 1121, facilitating the liquid in the water tank to be sprayed onto the glass from the through holes 1121.

[0058] In some alternative embodiments, exemplarily, the rib 13 extends towards one end away from the connection point, extends in the Y direction, and bends during the extension process.

[0059] Preferably, only one surface of the curled section 112 is provided with through holes 1121. The end of the rib 13 away from the connection point M extends in the Y direction, and bends in a direction away from the through holes 1121 during the extension process.

[0060] More preferably, the rib 13 extends in the Y direction, and during the extension process, the thickness of the rib 13 decreases.

[0061] When the bent rib 13 presses against the automotive glass, the relative contact area is larger. When the rib 13 adheres to the automotive glass, it can better clean the cleaning water sprayed from the through holes 1121 and better clean the automotive glass surface under the same pressure.

[0062] In some alternative embodiments, the U-shaped section 113 is connected to the arc-shaped outer surface of the curled section 112 at the tangent point.

[0063] In some alternative embodiments, the openings of the U-shaped sections 113 of the first body portion 11 and the second body portion 12 face each other.

[0064] The opposite arrangement of the openings of the two U-shaped sections 113 facilitates the insertion of the wiper strip skeleton into the openings of the two U-shaped sections 113, facilitating the installation of the wiper sheath body 1 on the wiper.

[0065] In some alternative embodiments, the U-shaped section 113 is divided into a side 1132 and a bottom section 1133. The side 1132 is provided with triangular convex teeth 11321. When the wiper skeleton 14 extends into the U-shaped section 113, the wiper skeleton 14 abuts against the bottom section 1133, and the side 1132 presses against the wiper skeleton 14.

[0066] The provision of the triangular convex teeth 11321 increases the friction between the wiper skeleton 14 and the wiper sheath, preventing relative sliding between the wiper sheath and the wiper skeleton 14 after installation.

[0067] In an alternative embodiment of the first aspect of the present utility model, a plurality of the through holes are distributed along the long side direction of the wiper sheath body 1.

[0068] In an alternative embodiment of the first aspect of the present utility model, the distances between the plurality of through holes 1121 are the same. In the first state, the plurality of through holes 1121 spray cleaning water onto the vehicle glass for uniformly cleaning the glass door.

[0069] The plurality of through holes 1121 replace the traditional vehicle wiper that sprays water from the engine hood, and the functional water spraying is more balanced.

[0070] In an alternative embodiment of the first aspect of the present utility model, the wiper sheath body 1 is integrally formed.

[0071] The second aspect of the present utility model proposes a wiper equipped with the above-mentioned wiper sheath 1.

[0072] The above-described embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included within the protection scope of the present application.
