[0031] The following specific embodiments illustrate the implementation manners of the present disclosure. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification.

[0032] It should be noted that the structures, ratios, sizes, etc. shown in the attached drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limited conditions for the implementation of the present disclosure. Therefore, they do not have a technical essence. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present disclosure can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present disclosure. At the same time, the terms such as "upper" and "one" cited in this specification are only for the convenience of clear narration and are not used to limit the scope for the implementation of the present disclosure. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present disclosure.

[0033] To understand the present disclosure more clearly, the following specifically describes each embodiment of the present disclosure with reference to the accompanying drawings.

[0034] The present disclosure provides a retaining arm 1 for a windshield wiper 2. Please refer to Figures 1 to 2, the holding arm 1, together with components such as the arm base 3 and the wiper blade 5, constitutes the windshield wiper 2. The holding arm 1 has an elongated shape extending in the longitudinal direction, which is the length direction of the holding arm 20. One end of the holding arm 1 is pivotally connected to the arm base 3 so that the holding arm 1 can move relative to the arm base 3 between a working position close to the windshield and a maintenance position away from the windshield. The other end of the holding arm 1 is connected to the wiper blade 5 abutting against the windshield, so as to drive the wiper blade 5 to reciprocate relative to the windshield when the holding arm 1 is in the working position, thereby scraping off rainwater, dust, etc. on the windshield. The hose 4 (also referred to as a water delivery pipe) is accommodated and fixed in the holding arm 1 along the longitudinal direction to prevent the hose 4 from falling off and being damaged and affecting the appearance, and the holding arm 1 of the present disclosure does not need to be additionally provided with a bottom cover.

[0035] Figure 3 and Figure 4 shows a partial enlarged view and a cross-sectional view of the holding arm 1 of the first embodiment, wherein Figure 3 also shows the arm base 3 connected to one end (the right end as shown in the figure) of the holding arm 1, but this does not affect those skilled in the art to understand the structure of the holding arm 1 described in the present disclosure. As shown in the figure, the holding arm 1 includes a holding arm main body 10 and at least one tongue 20. The holding arm main body 10 has an elongated shape extending in the longitudinal direction (as Figure 2 shown), and has an accommodating space capable of accommodating the hose 4. The tongue 20 is disposed in the accommodating space of the holding arm main body 10 for fixing the hose 4 to prevent the hose 4 from being exposed and damaged and affecting the appearance.

[0036] Specifically, the holding arm main body 10 includes a top wall 13 and a first side wall 11 and a second side wall 12 (collectively referred to as side walls 11, 12) connected to the longitudinal edges of the top wall 13, so that the holding arm main body 10 has a substantially U-shaped cross-section, that is, an accommodating space capable of accommodating components such as the hose 4. The tongue 20 is disposed on the first side wall 11 and / or the second side wall 12 and is located in the accommodating space for fixing the hose 4.

[0037] In this embodiment, the tongue 20 may be substantially V-shaped and include a first section 21 and a second section 22. The first section 21 is connected to the free edge of the first side wall 11 and extends close to the first side wall 11 and toward the top wall 13, so that the first section 21 may be substantially parallel to the first side wall 11. The second section 22 is connected to an end of the first section 11 close to the top wall 13 and extends toward the top wall 13 and toward the second side wall 12, that is, the second section 22 deviates toward the second side wall 12 while extending toward the top wall 13, so that the plane where the second section 22 is located may intersect the top wall 13 and the first side wall 11 at the same time. There is a gap between the free end of the second section 22 and the top wall 13, the size of which is smaller than the outer diameter of the hose 4 and can pass through when the hose 4 is deformed. With such arrangement, the hose 4 can be squeezed to deform and pass through the above-mentioned gap, thereby fixing / clamping the hose 4 on the tongue 20, especially fixing / clamping the hose 4 between the second section 22 of the tongue 20 and the retaining arm body 10, or in other words, fixing the hose 4 in the space defined by the second section 22 of the tongue 20 and the top wall 13 and the first side wall 11, thereby preventing the hose 4 from falling off and being damaged. The installation is simple and easy, and the retaining arm 1 has a simple structure and is easy to manufacture (for example, it can be manufactured by a stamping process), without the need to additionally provide a bottom cover and other components, thus saving materials.

[0038] The following will describe different embodiments of the present disclosure. To simplify the description, the following will mainly describe the differences between the embodiments, and the similarities will not be repeated. In addition, the same elements in the embodiments of the present disclosure are marked with the same reference numerals to facilitate comparison between the embodiments.

[0039] Figure 5 , Figure 6A and Figure 6B The partial enlarged view and cross-sectional view of the holding arm 1 of the second embodiment are shown. As shown in the figure, the tongue 20 can be formed by a deformed portion of the first side wall 11 or the second side wall 12. For example, the deformed portion can be folded along a folding line 30 toward the inside of the accommodating space of the holding arm body 10 to form the tongue 20 for fixing the hose 40.

[0040] Specifically, the holding arm body 10 includes a top wall 13 and a first side wall 11 and a second side wall 12 connected at the longitudinal edge of the top wall 13, so that the holding arm body 10 has a substantially U-shaped cross section, that is, it has an accommodating space capable of accommodating components such as the hose 4. The tongue 20 can be formed by a deformed portion of the first side wall 11.

[0041] In one embodiment, a U-shaped slit may be formed on the first side wall 11 through a stamping process, and the portion surrounded by the U-shaped slit may be defined as the deformed portion of the first side wall 11. The opening of the U-shaped slit may face the free end of the first side wall 11, so that the deformed portion is still connected to the first side wall 11 on the first side close to the free end of the first side wall 11, and the deformed portion is disconnected from the first side wall 11 on the second side relative to the first side and the portion between the first side and the second side. Thus, the deformed portion can be folded inward at an angle (such as folding an acute angle, but the present disclosure is not limited thereto. For example, when the opening of the U-shaped slit faces the top wall 13, an obtuse angle should be folded inward into the accommodating space to form the tongue 20) along the folding line 30 at the connection with the first side wall 11 (as shown in Figure 6A and Figure 6B ), to form the tongue 20 for fixing the hose 4. The above arrangement in this embodiment can directly utilize the material of the first side wall 11 to form the tongue 20. Compared with the first embodiment, it can further save materials and reduce costs.

[0042] As Figure 5 shown, the tongue 20 in this embodiment may be generally square. The tongue 20 is connected to the first side wall 11 at the folding line 30, where the folding line 30 may be generally parallel to the longitudinal direction, that is, parallel to the extending direction of the holding arm main body 10. The tongue 20 extends from the folding line 30 toward the top wall 13 and toward the second side wall 12. That is to say, the tongue 20 will shift toward the second side wall 12 while extending toward the top wall 13, so that the plane where the tongue 20 is located will intersect the first side wall 11 and the top wall 13 at the same time. There is a gap between the tongue 20 and the top wall 13, and the size of the gap is smaller than the outer diameter of the hose 4 and can pass through in the case of deformation of the hose 4. With such an arrangement, the hose 4 can be squeezed to deform and pass through the above gap, and then the hose 4 is fixed / held between the tongue 20 and the holding arm main body 10, avoiding the hose 4 falling off from the holding arm 1 and being damaged. The structure of the holding arm 1 disclosed in this embodiment is simple and easy to manufacture, and the installation of the hose 4 is simple and feasible. At the same time, since the tongue 20 is directly formed by using a part of the first side wall 11 or the second side wall 12, this further reduces the cost and saves materials.

[0043] Figure 7 , Figure 8A and Figure 8B show a partial enlarged view and a cross-sectional view of the holding arm 1 of the third embodiment. As shown in the figure, the tongue 20 may also be formed by the deformed portion of the first side wall 11 or the second side wall 12. For example, the deformed portion may have a bent hook portion, and the deformed portion is folded inward along a folding line 30 into the accommodating space of the holding arm main body 10 to form the tongue 20, where the tongue 20 has a hook portion that can support / fix the hose 40.

[0044] Specifically, the holding arm body 10 includes a top wall 13, a first side wall 11 and a second side wall 12 connected to the longitudinal edges of the top wall 13, such that the holding arm body 10 has a substantially U-shaped cross-section, that is, a receiving space capable of accommodating components such as a hose 4. The tongue 20 can be formed by a deformed portion of the first side wall 11.

[0045] In one embodiment, a substantially inverted U-shaped slit can be formed on the first side wall 11 via a stamping process, wherein the opening of the inverted U-shaped slit can face the longitudinal direction, that is, the extending direction of the holding arm body 10, and the inverted U-shaped slit has an arc-shaped depression on a side away from its opening, such that the deformed portion surrounded by the inverted U-shaped slit has a hook portion bent toward the top wall 13, as Figure 8A and 8B shown. The deformed portion surrounded by the inverted U-shaped slit is connected to the first side wall 11 on a first side close to the opening of the U-shaped slit, and the remaining portions are all disconnected from the first side wall 11. In this way, the deformed portion can be folded inward by an angle (for example, 90 degrees) along the folding line 30 at the connection with the first side wall 11 (as Figure 7 and Figure 8A shown) toward the inside of the receiving space of the holding arm body 10 to form the tongue 20 for supporting / fixing the hose 4. The above arrangement of this embodiment can directly utilize the material of the first side wall 11 to form the tongue 20. Compared with the first embodiment, it can further save materials and reduce costs, and the tongue 20 with the above hook portion can fix the hose 4 more firmly, preventing the hose 4 from detaching from the holding arm 1 and being damaged.

[0046] As Figure 8A and 8BAs shown, the tongue 20 of this embodiment can be roughly in the shape of a straight line, and has a hook portion bent toward the top wall 13 at the free end of the straight line, which is used to support / fix the hose 4. The tongue 20 is connected to the first side wall 11 at the folding line 30, wherein the folding line 30 can be roughly perpendicular to the longitudinal direction, that is, perpendicular to the extension direction of the holding arm body 10. The tongue 20 extends from the folding line 30 of the first side wall 11 toward the second side wall 12, so that the tongue 20 can be roughly perpendicular to the extension direction of the hose 40, thereby facilitating the fixing of the hose 4. The hook portion at the free end of the tongue 20 facing the inner side of the hose 40 can be roughly semicircular, and the diameter of the semicircle can be roughly equal to or slightly larger than the outer diameter of the hose 4, so that the hook portion of the tongue 20 can prevent the hose 4 from shaking when supporting the hose 4; and the hook portion of the tongue 20 can be roughly rectangular or other regular shapes on the outer side away from the hose 40 to facilitate stamping. There is a gap between the hook portion of the tongue 20 and the top wall 13, the size of which is smaller than the outer diameter of the hose 4 and can pass through when the hose 4 is deformed. In this way, the hose 4 can be squeezed to deform and supported / fixed between the hook portion of the tongue 20 and the holding arm body 10 through the above gap to prevent the hose 4 from falling off the holding arm 1. The holding arm 1 disclosed in this embodiment has a simple structure and is easy to manufacture, and the installation of the hose 4 is simple and easy. At the same time, since the tongue 20 is directly formed by using a part of the first side wall 11 or the second side wall 12 and has a hook portion bent toward the top wall 13, this can reduce costs and save materials while more firmly fixing the hose 4 to prevent the hose 4 from shaking.

[0047] The retaining arm 1 in each embodiment of the present disclosure can be a single piece, that is, the tongue 20, the first side wall 11, the top wall 13 and the second side wall 12 can be a single piece, that is, an integrated structure, so that the above structure can be formed by a stamping process, which is simple to manufacture and can avoid the problem of wasting time due to the separate installation of the tongue 20. Of course, the present disclosure is not limited to this, for example, the tongue 20 can also be fixed to the first side wall 10 or the second side wall 20 by other means such as fasteners or adhesive, as long as the hose 4 can be fixed and the bottom wall of the retaining arm 1 can avoid additional installation of a bottom cover.

[0048] The material of the retaining arm 1 of the present disclosure is metal, that is, the material of the tongue 20 is metal, which avoids the problem in the prior art that the hose 40 is easily aged and damaged due to the use of a plastic bottom cover to fix the hose 40.

[0049] Although only one tongue 20 is shown on the retaining arm 1 shown in each embodiment of the present disclosure, the present disclosure is not limited thereto, and technicians can arrange multiple tongues 20 on the retaining arm 1 at intervals along the longitudinal direction according to actual conditions.

[0050] The tongue 20 described in the embodiments of the present disclosure is mainly described as being provided on the first side wall 11. However, the present disclosure is not limited thereto. For example, the tongue 20 can also be provided on the second side wall 12 or on both side walls 11 and 12, as long as the hose 40 can be fixed.

[0051] In addition, the tongue 20 described in the embodiments of the present disclosure is mainly described as being generally V-shaped or linear in shape, etc. However, the present disclosure is not limited thereto. For example, the tongue 20 can also be set to other shapes as needed, as long as the hose 40 can be fixed.

[0052] In summary, the present disclosure provides a retaining arm for a windshield wiper. By providing a tongue for fixing a hose in the accommodating space of the retaining arm body, it is possible to prevent the hose from falling off and being damaged, and to avoid affecting the appearance. Moreover, in the present disclosure, by providing a plurality of tongues facing the inside of the accommodating space at the free ends of the first side wall or the second side wall, the hose can be clamped between the tongues and the retaining arm body to prevent the hose from falling off. The installation is simple and easy, and the structure of the retaining arm 1 is simple and easy to manufacture (for example, it can be manufactured by a stamping process), and there is no need to additionally provide components such as a bottom cover. Furthermore, in the present disclosure, the design of forming the tongue by folding the deformed part of the first side wall or the second side wall toward the inside of the accommodating space directly uses the material of the first side wall or the second side wall to form the tongue. In this way, while achieving the above effects, the cost can be further saved, and the materials can be saved.

[0053] The present disclosure also provides a windshield wiper 2, as Figure 1 and Figure 2 shown. The windshield wiper 2 includes the retaining arm 1 described above.

[0054] The present disclosure also provides a vehicle, which includes the windshield wiper arm 2 described above.
