Description

Support, wiper and vehicle

Technical Field

The utility model relates to a support, wiper and vehicle that have this support for being used for wiping the windshield of vehicle.

Background

Wipers play an important role in vehicles, in order to clear the windscreen of rain or other dirt that affects the driver's view, in order to ensure driving safety.

Conventional wipers separate the wiper assembly from the cleaning assembly. The cleaning assembly is concealed under the front hatch. When the windshield requires cleaning, the cleaning assembly sprays a cleaning fluid onto the surface of the windshield and the wiper assembly begins to operate. This may result in a large amount of cleaning fluid being required to clean the windshield since the cleaning fluid is sprayed over the entire surface.

In recent years, wipers incorporating a nozzle for cleaning fluid into the wiper assembly have increasingly appeared. For this purpose, the nozzle and the cleaning fluid reservoir are connected by a conduit. The conduit extends along a wiper arm of the wiper assembly between the wiper arm and the windshield. However, as can be seen from fig. 10, since the wiper arm generally has a bent shape, the guide tube 50 may be easily exposed from below the relevant part 40 of the wiper arm, which adversely affects the visual appearance. In addition, the exposed conduit is more easily affected by the external environment, such as premature aging due to exposure to sunlight, damage due to foreign substances, and the like, which is disadvantageous in terms of the life of the conduit.

Detailed Description

Embodiments of the present invention are exemplarily described below. As those skilled in the art will appreciate, the illustrated embodiments may be modified in various different ways without departing from the inventive concept. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive. In the following, the same reference numbers generally indicate functionally identical or similar elements.

Fig. 1 schematically shows an embodiment of a wiper 1 according to the invention, which wiper 1 is used for wiping a windscreen of a vehicle.

The wiper 1 includes: a wiper arm 2 including a wiper arm base 10 and at least one arm portion connected in an elongated shape, the wiper arm 2 being swingable back and forth in a direction R via a not-shown driving mechanism, such as a motor, wherein a motion transmitting mechanism, such as a link mechanism, may be arranged between the driving mechanism and the wiper arm 2 to transmit a motion of the motor to the wiper arm 2; a wiper blade 3, which is held on the wiper arm 2, wherein the wiper arm 2 moves the wiper blade 3 on the windshield as the wiper arm 2 moves.

The wiper arm mount 10 may be a metal casting, for example an aluminium casting, and at the first end 10A there is left a through hole 11 for the above-mentioned drive mechanism, into which through hole 11 the output shaft of the drive mechanism can be inserted, thus establishing a non-rotatable connection with the wiper arm mount 10. If necessary, a cover 12 can be provided which covers the through-opening 11 after the connection has been established.

The arm portion can be understood as a member connected to the wiper arm base 10. In the case where a plurality of arms are provided, the arms may have different cross-sectional shapes from each other, such as U-shape, square shape, or the like. In particular for the U-shaped arms and the square rod-shaped arms, they can be connected by clinching, i.e. one end of the U-shaped arm covers one end of the rod-shaped arm and they are fixedly connected to each other. Of course, other means of fixed attachment may be possible. The arm may also be referred to as an extension arm, arm lever, adapter, or the like.

In the example shown, a U-shaped arm portion, which may also be referred to as extension arm 20, and a rod-shaped arm portion, which may also be referred to as arm bar 30, are shown.

The wiper arm base 10 and the extension arm 20 are pivotally connected to each other at the second end 10B, for example via a pivot 21. The extension arm 20 here has a U-shaped cross section over substantially its entire length, i.e. apart from the connecting section with the adjacent point. A preloading means in the form of a spring 23 is arranged in the interior space of the extension arm 20 for exerting a predetermined force on the wiper arm 2 after the wiper 1 has been mounted on the window in order to press the wiper 1, more precisely the wiper blade 3 of the wiper 1, against the windscreen. As can be seen from fig. 4, the springs 23 are each connected via a first hook-shaped end 23A by means of a C-shaped element 22 to the second end 10B of the wiper arm holder 10, and are hooked directly into the bore 33 via the second hook-shaped end 23B. The hole may be formed in a lug, not shown, of the side wall of the extension arm 20 or in the end 30B of the arm bar 30.

Also shown schematically in the example of fig. 1 are some jets 82 for cleaning fluid provided on the wiper blade 3. It is noted that the spout 82 may be provided on the relevant part of the wiper blade 3, for example, on the float guard of the wiper blade 3, along the entire longitudinal direction of the wiper blade 3. For this purpose, a channel, not shown, for a cleaning fluid can be integrally provided in the float trap. In this example, a connector 80 of the wiper blade 3 as shown in fig. 12 may be employed, which has a structure 83 for releasing the connection with the wiper arm 2 and has an interface 81 for connecting with the passage.

Alternatively, in a not shown example, the spout may also be provided directly at the wiper arm. For example, the nozzle is provided by a nozzle separately mounted on the extension arm and/or arm shaft of the wiper arm.

To this end, the wiper 1 may further comprise a conduit 50 which is guided along the extension of the wiper arm 2 and which establishes a fluid connection with the spout 82 for conveying cleaning fluid from a fluid reservoir, not shown, to the spout. To this end, the conduit has a first end 51 connected to the reservoir and a second end 52 connected to the spout.

As is apparent from fig. 1 to 3, the wiper 1, in particular the arm 30 thereof, has a curved course. The guide tube 50 is guided on the underside of the wiper arm 2, i.e. on the side facing the windscreen.

In the case of a pipe, it is desirable to utilize the existing wiper arm, or at least to partially utilize the relevant components of the existing wiper arm, such as the extension arm, arm lever, adapter, etc., in order to reduce costs. Here, the desired guidance of the guide tube 50 at the wiper arm 2, i.e. without emerging from the side of the wiper arm 2, should likewise be ensured.

As can also be seen from fig. 4, a channel for the guide tube 50 is left in the wiper arm seat 10, which channel is formed by hook portions 13, 14 provided on one longitudinal side of the wiper arm seat 10, which are arranged in an oppositely staggered manner.

As can also be seen from fig. 1 to 3, a bracket 60 is additionally provided separately, which bracket 60 is arranged on the arm 30. The number of the brackets 60 can be selected according to actual requirements. In the example shown, three brackets are arranged on the arm 30. The bracket 60 will be described in detail below.

In the example shown, connected to the arm 30 is an adapter 40, which can also be referred to as an arm, for establishing a connection with a wiper arm. The adapter 40 has a first section 40A, a second section 40B and a third section 40C therebetween forming a bent shape. Specifically, a first bend B1 is formed between the first section 40A and the third section 40C, and a second bend B2 is formed between the second section 40B and the third section 40C. The adapter 40 is fixedly connected, for example riveted, to the front end 30A of the arm 30 at the end of the first section 40A, see fig. 5, 6, and to a connector 80 of the wiper blade 3 at the end of the second section 40B, see fig. 12. The adaptor 40 has a U-shaped cross section in addition to the portion connecting the front end 30A of the arm lever 30. Here, the arm lever 30 may be a standard piece, thereby reducing costs.

For this adapter 40, a first embodiment of a holder 60 is proposed, see fig. 8. The holder 61 of the first embodiment includes two sheet-like portions 64 and a bottom plate portion 62 connected to each sheet-like portion 64. The end side of the sheet portion 64 is left with a slit 67 and resiliently opens. The respective tab 64 forms with the inner side of the connecting portion 63 of the bottom plate part 62 and the inner side of the bottom plate part 62 a connecting portion 65, the cross section of which connecting portion 65 matches the cross section of the arm 30 and forms a snap-in interface for engaging on the arm 30, which is open on one side, i.e. on the side facing the windscreen. At least end-side sections of the flaps 64 facing away from the floor part 62 are inclined towards one another to form an accommodation space 66 for holding the conduit 50. The receiving space 66 thus has a cross section which tapers at least in the direction of the gap 67.

The bottom plate portion 62 is provided at one end of the sheet portion 64 over a part of the longitudinal length of the sheet portion 64. Thus, the connecting portion 65 also extends over a portion of the longitudinal length of the tab 64. The respective tab 64 has a projection 69 at the other end, which projection 69 projects into the section of the adapter 40 having a U-shaped cross section at the beginning of the section, wherein the beginning is at the first bend B1 of the first section 40A and the third section 40C, the conduit 50 is guided via the tab 64 to the third section 40C of the adapter 40, and the second end 52 of the conduit 50 is below the second section 40B for the wiper blade, see fig. 5. Thus holding the catheter 50 securely under the adapter.

As seen from the illustrations of fig. 5 and 6, in the mounted state, the bottom plate portion 62 of the bracket 61 of the first embodiment is placed adjacent to the first section 40A of the adapter 40; a portion of the length of the tab 64 extends below the first section 40A of the adapter 40; the projections 69 at the ends of the tabs 64 project into the U-shaped section of the adapter 40, as can be seen particularly clearly in the section through the line a-A, B-B, C-C in fig. 5, which is shown in fig. 7a, 7b and 7C, respectively, in which the catheter 50 is located between the two tabs 64 of the holder 61.

The projection 69 may have a rib 69A on a side facing away from the receiving space 66. In the case where the widths of the U-adapters 40 are different, matching can be performed by adjusting the heights of the ribs 69A, thereby reducing the cost of the mold.

As can also be seen from fig. 7c, a bulge 68 is formed on the inside of the section of the bracket 61 with the base plate 62, which bulge can form a projection for the arm 30.

Preferably, the floor portions 62, 72 have a thinner thickness than the tabs 64, 74 to facilitate resilient expansion of the tabs 64, 74.

Preferably, the bracket 61 is a unitary piece. For example, the stent is injection molded by plastic having good physical mechanical properties and weather resistance, such as polybutylene terephthalate (PBT), acrylonitrile-styrene-acrylate copolymer (ASA) and Polycarbonate (PC) composite, polyoxymethylene resin (POM), and the like. The stent may also be formed of metal.

In fig. 9 to 11, there are shown other embodiments of the holder 60, respectively, which have substantially the same structure as the holder 61 of the first embodiment.
