Abstract
Description
Technical Field
[0001] This disclosure pertains to the field of windshield wipers, and specifically relates to a windshield wiper retaining arm, a windshield wiper including the retaining arm, and a vehicle including the windshield wiper. Background Technology
[0002] A vehicle's windshield wipers reciprocate against the windshield during wiping operations to remove rainwater, dust, and other debris. Typically, a windshield wiper includes an arm mount, a retaining arm, and a wiper blade connected in sequence. One end of the retaining arm is pivotally connected to the arm mount, and the other end is connected to the wiper blade. For wipers that spray water, a water hose is usually also included. The water hose is typically concealed within the retaining arm's cavity to prevent it from being visible from the outside of the wiper.
[0003] For compact vehicle designs, the space between the wiper arm and the vehicle may be very small. In such cases, a new type of wiper arm is needed to match the vehicle body design and avoid interference between the wiper arm and the vehicle body. Utility Model Content
[0004] In response to the problems and needs mentioned above, this disclosure proposes a novel wiper retaining arm that solves the aforementioned problems and brings other technical benefits by adopting the following technical features.
[0005] The objective is achieved by a retaining arm for a windshield wiper according to an embodiment of the present disclosure, the retaining arm for driving the wiper blade to wipe the windshield of a vehicle, the retaining arm having a longitudinally extending direction, one end of the retaining arm being connected to a wiper arm seat, and the other end being connected to the wiper blade of the windshield wiper, wherein the retaining arm has a first sidewall and a second sidewall arranged opposite to each other and a base connecting the first sidewall and the second sidewall, the first sidewall and the second sidewall and the base forming an open cavity for receiving a conduit of the windshield wiper.
[0006] The retaining arm according to this disclosure may also have one or more of the following features, individually or in combination.
[0007] According to one embodiment of this disclosure, at the end furthest from the base, the first sidewall and the second sidewall have different heights relative to the main plane of the base.

[0025] For ease of description, the accompanying drawings of this disclosure have correspondingly simplified or omitted components commonly used in the art, such as external connecting lines and other components unrelated to the description of this disclosure. These omitted or simplified components do not affect a person skilled in the art's understanding of the content of this disclosure.
[0026] This disclosure provides a wiper retaining arm 10, please refer to Figures 1 to 2 The wiper consists of a retaining arm 10, a wiper arm seat 20, a wiper blade (not shown), and other components. The retaining arm 10 has an elongated shape extending longitudinally, which is the length direction of the retaining arm 10. One end of the retaining arm 10 is pivotally connected to the wiper arm seat 20, which can move the retaining arm 10 under the drive of a drive mechanism. The other end of the retaining arm 10 is connected to the wiper blade against the windshield, so that the wiper blade reciprocates relative to the windshield under the drive of the wiper arm seat 20, thereby wiping away rainwater and dust from the windshield. A conduit 30 (also called a water pipe) is housed and fixed within the retaining arm 10 in the longitudinal direction.
[0027] refer to Figure 1 and Figure 2 The wiper retaining arm 10 has an elongated shape and extends longitudinally. Now see Figure 3 , Figure 3 It is the retaining arm 10 of the windshield wiper. Figure 2The image shows a cross-sectional view cut by dashed lines. The retaining arm 10 has a U-shaped cross-section and has a first sidewall 11 and a second sidewall 12 arranged opposite each other, and a base 13 connecting the first sidewall 11 and the second sidewall 12. The sidewall 11 and the base 13 form an open cavity 14 for receiving the wiper duct 30. The wiper duct 30 is guided and concealed within the cavity 14.
[0028] In one example, such as Figure 3 As shown, at the end furthest from the base 13, the first sidewall 11 and the second sidewall 12 have different heights relative to the main plane of the base 13. Windshield wipers are typically positioned at the bottom of the vehicle's windshield. In some cases, such as... Figure 2 and 3 As shown, due to the limited space in the engine compartment and the need to house the motor driving the windshield wipers, this area may have a non-flat shape to accommodate the motor. Setting the two side walls of the wiper retaining arm 10 to have different heights relative to the main plane of the base 13 can better accommodate this non-flat shape and avoid interference between the wiper and the vehicle body.
[0029] The height difference h between the first sidewall 11 and the second sidewall 12 can be selected and designed as needed, and this application does not constitute a limitation. In one example, the height difference h between one of the first sidewall 11 and the second sidewall 12 relative to the main plane of the base 13 and the other is 1-5 mm. Preferably, the height difference h between one of the first sidewall 11 and the second sidewall 12 relative to the main plane of the base 13 and the other is 2 mm.
[0030] In one example, the first sidewall 11 is higher than the second sidewall 12 relative to the main plane of the base 13, where the first sidewall 11 is closer to the wiper blade than the second sidewall 12. That is, the sidewall closer to the wiper blade has a higher height relative to the main plane of the base 13. This is because the other side is closer to the bottom of the vehicle's windshield, where the vehicle's shape may have an uneven structure; this design better matches the vehicle's shape and avoids interference.
[0031] like Figure 4 and 5 As shown, the wiper duct 30 is housed within a cavity 14 formed by the first sidewall 11, the second sidewall 12, and the base 13 in the retaining arm 10. To prevent the wiper duct 30 from falling out of the retaining arm 10, a tab 15 is provided at the edge of the second sidewall 12, extending towards the first sidewall 11 to secure the wiper duct 30. The position and number of tabs 15 can be arranged as needed. Providing tabs 15 on the second sidewall 12 facilitates the guidance and arrangement of the wiper duct 30 and avoids increasing the thickness of the wiper arm.
[0032] In another example, the tab 15 may also be disposed at the edge of the first sidewall 11 and extend toward the second sidewall 12, without any specific limitation in this application.
[0033] In one example, such as Figure 5 As shown, the end 16 of the tab 15 extends toward the base 13 of the retaining arm 10 to further prevent the conduit 30 from falling out of the cavity 13. Specifically, the end 16 of the tab 15 is folded upward relative to its body, forming a groove for receiving the conduit 30 together with the second sidewall 12. The conduit 30 is locked into the groove, thereby further preventing the conduit 30 from falling out of the cavity 14. The end 16 of the tab 15 is slightly inclined toward the second sidewall 12 to achieve a better effect in preventing the conduit from falling out. The size of the groove is preferably slightly smaller than the diameter of the conduit 30. Since the conduit is flexible, this can better hold the conduit 30 in place and prevent it from coming out of the retaining arm 10.
[0034] In another example, the retainer can be at least partially closed by providing a cover (not shown) at the opening of the cavity 13 of the retaining arm 10, the cover being arranged opposite to the base 13 of the retaining arm, which can also prevent the catheter 30 from falling out.
[0035] The retaining arm 10 of the wiper is formed as a single piece to simplify the assembly process and reduce costs.
[0036] Through the above design, the two side walls of the wiper retaining arm of this disclosure have different heights relative to the main plane of the base of the retaining arm. This design can improve the clearance between the wiper retaining arm and the vehicle body, avoiding interference. Forming protrusions for retaining the water pipe on the side walls eliminates the need for additional fixing structures, simplifying the assembly process and reducing costs.
[0037] This disclosure also provides a vehicle that includes the windshield wipers described above.
[0038] Certain features, structures, or characteristics in one or more embodiments of this disclosure may be appropriately combined.
[0039] The foregoing description is illustrative of the present disclosure and should not be construed as limiting it. While several exemplary embodiments of the present disclosure have been described, those skilled in the art will readily understand that many modifications may be made to the exemplary embodiments without departing from the novel teachings and advantages of the present disclosure. Therefore, all such modifications are intended to be included within the scope of the present disclosure as defined in the claims. It should be understood that the foregoing description is illustrative of the present disclosure and should not be construed as limiting it to the specific embodiments disclosed, and modifications to the disclosed embodiments and other embodiments are intended to be included within the scope of this disclosure.
