Description

Technical Field

[0001] The present disclosure relates to a retaining arm, a windshield wiper including the retaining arm, and a vehicle including the windshield wiper, and more particularly to a retaining arm including a vibration damping block. Background Art

[0002] The windshield wiper of a vehicle moves back and forth against the windshield of the vehicle during the wiping operation to scrape off rain, dust, etc. on the windshield. Generally, the wiper comprises an arm seat, a retaining arm and a wiper blade which are connected in sequence. One end of the retaining arm is pivotally connected to the arm seat, and the other end of the retaining arm is connected to the wiper blade. When the retaining arm is in the working position, the wiper blade is pressed against the windshield of the vehicle and is driven to perform a reciprocating motion to perform a wiping operation. When the wiper blade needs to be replaced or the windshield needs to be cleaned, the operator needs to manually operate the retaining arm to pivot the retaining arm away from the windshield to a maintenance position relative to the arm seat, that is, to bend the retaining arm to make it stand up relative to the arm seat.

[0003] Generally, the windshields of large vehicles are also larger. In order to match the larger windshields, the retaining arms need to be longer to drive the wiper blades to perform wiping operations. However, a longer retaining arm will reduce its rigidity and increase its weight, which means that when the retaining arm returns to the working position from the maintenance position due to collision or other reasons, it will have a larger deformation and a larger impulse, which may cause the bottom side of the retaining arm to hit the windshield, causing damage to the windshield.

[0004] Therefore, those skilled in the art are committed to developing a new type of retaining arm to solve the above-mentioned defects of the prior art. Summary of the invention

[0005] The purpose of the present disclosure is to provide a retaining arm of a wiper, which can effectively avoid the above-mentioned defects of the prior art.

[0019] In one or more embodiments, the damping block further includes grooves provided on both sides of the mounting hole to accommodate and snap the convex wings of the tongue.

[0020] With the above arrangement of the damping block, the present disclosure can prevent the damping block from falling off the tongue and increase the fixing strength between the two.

[0021] In one or more embodiments, a boss extending toward the top wall is provided on a side of the damping block away from the fixed end of the tongue.

[0022] With the above arrangement of the damping block, the present disclosure can prevent the water delivery pipe 4 from falling off the holding arm 1.

[0045] The following illustrates the implementation manners of the present disclosure through specific specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present disclosure from the content disclosed in this specification.

[0046] 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 under which the present disclosure can be implemented. Therefore, they do not have technical substance. 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 under which the present disclosure can be implemented. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope within which the present disclosure can be implemented.

[0047] To understand the present disclosure more clearly, the following specifically describes each embodiment of the present disclosure with reference to the accompanying drawings.

[0048] The present disclosure provides a holding arm 1 of a windshield wiper 2. Please refer toFigures 1 to 2 The holding arm 1, together with components such as the arm base 3 and the wiper blade (not shown in the figure), constitutes the windshield wiper 2. The holding arm 1 has an elongated shape extending in the longitudinal direction, and this longitudinal direction 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 that abuts against the windshield to drive the wiper blade to reciprocate relative to the windshield, thereby scraping off rainwater, dust, etc. on the windshield.

[0049] Please refer to Figures 3 to 6 The holding arm 1 includes a holding arm body 10, a tongue 20, and a shock-absorbing block 30. The holding arm body 10 has an elongated shape extending in the longitudinal direction and includes a bottom side close to the windshield and a top side facing away from the windshield. The tongue 20 is provided on the bottom side of the holding arm body 10. The shock-absorbing block 30 is fixed to the tongue 20 and covers the surface of the tongue 20 facing the windshield (collectively referred to as the lower surface of the tongue 20 hereinafter). With such a setting, when the holding arm 1 returns from the maintenance position to the working position, at least a part of the shock-absorbing block 30 can be clamped between the holding arm body 10 and the windshield to buffer the impact of the holding arm and prevent the windshield from being damaged due to a hard collision of the holding arm 1.

[0050] Specifically, the holding arm body 10 includes a top wall 13 and a first side wall 11 and a second side wall 12 connected to the longitudinal edges of the top wall 13, so that the holding arm body 10 has a substantially U-shaped cross-section for accommodating components such as a water delivery pipe 4. The tongue 20 is provided on one of the first side wall 11 and the second side wall 12 and extends towards the other side wall. In this embodiment, the tongue 20 is provided on the first side wall 11 and extends towards the second side wall 12. The first side wall 11 and the second side wall 12 are located between the tongue 20 and the top wall 13. That is to say, when the holding arm 1 is in the working position, the tongue 20 is closer to the windshield relative to the first side wall 11 and the second side wall 12. In this way, when the holding arm 1 returns from the maintenance position to the working position, the shock-absorbing block 30 covering the lower surface of the tongue 20 can contact the windshield first, avoiding damage to the windshield.

[0051] In order to avoid the possibility that the first side wall 11 and / or the second side wall 12 of the holding arm 1 hits the windshield due to the small stiffness of the holding arm 1, technicians can set a plurality of tongues 20 at intervals in the longitudinal direction of the holding arm 1 according to the actual situation. In this embodiment, 4 tongues 20 are provided on the holding arm 1, but the present disclosure is not limited thereto.

[0052] Please continue to refer to Figure 5 and Figure 6, the tongue 20 is arranged substantially parallel to the top wall 13. Compared with the prior art in which the tongue is arranged to be offset toward the top wall 13 in order to restrict the water pipe 4 to prevent it from falling off from the retaining arm 1, the tongue 20 parallel to the top wall 13 can effectively reduce the difficulty of the manufacturing process (such as the stamping process) and is more convenient for the installation of the vibration damping block 30.

[0053] In one embodiment, if Figure 5 and Figure 6 As shown, the tongue 20 may be substantially in a straight line shape, and has a fixed end connected to the first side wall 11 and a free end facing the second side wall 12. Specifically, the tongue 20 has a straight segment body 24 extending from the first side wall 11 toward the second side wall 12, and a pair of convex wings 23 are provided on opposite edges of the straight segment body 24 for fixedly connecting the vibration damping block 30. The above arrangement of the tongue 20 can simplify its structure and facilitate fixing the vibration damping block 30 on the tongue 20.

[0054] The convex wing 23 may be roughly in the shape of a right-angled triangular prism or a quadrangular prism with a right-angled trapezoidal bottom surface, with its inclined surface facing the free end of the protruding tongue 20, and the right-angled surface facing the fixed end of the protruding tongue 20. Such a configuration allows the inclined surface to serve as a guide surface of the convex wing 23 to guide the protruding tongue 20 to be inserted into the vibration damping block 30. Of course, the present disclosure is not limited to the above-mentioned structure of the convex wing 23, as long as the vibration damping block 30 can be fixed / fastened.

[0055] In one embodiment, 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 to avoid the need to separately install 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 bonding.

[0056] See also Figure 4 , Figures 5 to 9 , the vibration-damping block 30 mounted on the tongue 20 may be roughly in the shape of a block. The vibration-damping block 30 is provided with a mounting hole 31, into which the tongue 20 may be inserted. The mounting hole 31 is located so that the vibration-damping block 30 covering the lower surface of the tongue 20 (i.e., the vibration-damping block 30 sandwiched between the tongue 20 and the windshield) has a certain thickness, for example, in the range of 2 mm to 5 mm, to ensure the buffering / vibration-damping capacity of the vibration-damping block 30. In one embodiment, the mounting hole 31 may be a through hole, but the present disclosure is not limited thereto. For example, the mounting hole 31 may also be a blind hole, as long as the tongue 20 may be inserted into the mounting hole 31.

[0057] The vibration damping block 30 also includes grooves 32 disposed on both sides of the mounting hole 31. The grooves 32 are connected to the mounting hole 31 and are used to accommodate and clamp the convex wings 23 of the tongue 20 to prevent the vibration damping block 30 from falling off the tongue 20.Figure 6 and Figure 7 When the vibration damping block 30 needs to be installed, the installation hole 31 of the vibration damping block 30 is aligned with the free end of the tongue 20, and the vibration damping block 30 is moved towards the fixed end of the tongue 20, so that the tongue 20 is inserted therein until the convex wing 23 of the tongue 20 is clamped / locked in the groove 32 of the vibration damping block 30, that is, the installation is completed.

[0058] Please continue to refer to Figure 5 、 Figures 7 to 9 On the side of the vibration damping block 30 away from the fixed end of the tongue 20, a convex platform 33 extending towards the top wall 13 may be further provided to limit the water delivery pipe 4 to prevent it from falling off from the holding arm 1. In addition, on the side of the vibration damping block 30 close to the fixed end of the tongue 20, it may be arranged in a stepped shape so that the vibration damping block 30 can cover the entire lower surface of the tongue 20 without interfering with the first side wall 11 (as shown in Figure 5 ), so that the buffer area of the vibration damping block 30 can be increased, and further effectively prevent the windshield from being damaged due to the collision of the holding arm 1.

[0059] In one embodiment, the vibration damping block 30 may be a rubber part. For example, it may be made of ethylene propylene diene monomer (EPDM). The hardness of the vibration damping block 30 can be selected between 40 Shore hardness (SHA) and 80 Shore hardness (SHA) according to needs to effectively improve the anti-collision buffer capacity between the holding arm main body 10 and the windshield.

[0060] In the above embodiment of the present disclosure, by providing a tongue 20 extending from one side wall of the holding arm 1 towards the other side wall and fixing the vibration damping block 30 on the tongue 20, wherein the vibration damping block 30 covers the lower surface of the tongue 20, such an arrangement can make at least a part of the vibration damping block 30 clamped between the holding arm 1 and the windshield when the holding arm 1 returns from the maintenance position to the working position, buffer the impact of the holding arm 1, and avoid damage to the windshield.

[0061] However, since the vibration damping block 30 needs to be placed between the free end of the tongue 20 and the second side wall first and the vibration damping block 30 is moved towards the fixed end of the tongue 20 (i.e., towards the first side wall 11) during the installation of the vibration damping block 30, due to the limited / small distance between the first side wall 11 and the second side wall 12 of the holding arm 1, the above installation direction of the vibration damping block 30 may cause inconvenient installation. That is to say, the installation space of the vibration damping block 30 in this embodiment is small and the installation is inconvenient.

[0062] To overcome the above deficiencies, the present disclosure also proposes another embodiment of the holding arm 1, as shown in Figures 10 - 17As shown below. The following will describe this other embodiment of the present disclosure. For simplicity of description, the differences between this other embodiment and the foregoing embodiment will be mainly described in detail below, and the same parts will not be repeated. In addition, the same elements in the various embodiments of the present disclosure are labeled with the same reference numerals to facilitate comparison between different embodiments.

[0063] Please refer to Figure 10 、 Figure 11 and Figure 13 , in this other embodiment, a plurality of tongues 30 are also provided on the holding arm body 10. Specifically, the tongue 20 is fixed to the first side wall 11 and at least partially extends towards the second side wall 12. Of course, the present disclosure is not limited to this. For example, the tongue 20 can also be fixed to the second side wall 12 and at least partially extend towards the first side wall 11.

[0064] Specifically, the tongue 20 can be generally L-shaped. That is to say, the tongue 20 can include a first section 21 and a second section 22. The first section 21 is fixed to the first side wall 11 and extends towards the second side wall 12. The second section 22 is connected to one end of the first section 21 close to the second side wall 12 and extends at an angle relative to the first section 21. For example, it can extend at approximately 90 degrees relative to the first section 21. Such a setting can make the second section 22 located between the first side wall 11 and the second side wall 12 and extend substantially along the longitudinal direction. A pair of convex wings 23 are provided on the opposite edges of the second section 22 for fixedly connecting the damping block 30.

[0065] In one embodiment, the convex wing 23 can be generally in the shape of a right-angled triangular prism or a quadrangular prism with a right-angled trapezoidal base. Its inclined surface faces the free end of the tongue 20, and the right-angled surface faces the first side wall 11 of the tongue 20, so that the inclined surface can be used as a guiding surface to guide the tongue 20 to be inserted into the damping block 30. However, the present disclosure is not limited to the above structure of the convex wing 23, as long as it can fix / clamp the damping block 30.

[0066] The damping block 30 is also fixed on the tongue 20, and the damping block 30 covers the lower surface of the tongue 20 facing the windshield. Such a setting can, when the holding arm 1 returns from the maintenance position to the working position, make at least a part of the damping block 30 clamped between the holding arm 1 and the windshield, slow down the impact of the holding arm 1 on the windshield, and avoid breakage of the windshield.

[0067] Please refer to Figure 11 、 Figure 12 、 Figures 14 to 17, a mounting hole 31 is provided on the damping block 30, and the lug 20 can be inserted into the mounting hole 31. In one embodiment, in order to increase the area covered by the damping block 30, the mounting hole 31 of the damping block 30 can be set to be generally L-shaped, so that both the first section 21 and the second section 22 of the lug 20 can be inserted into the mounting hole 31. Specifically, since the extending directions of the first section 21 and the second section 22 of the lug 20 are different, in order to make it more convenient to mount the damping block 30 onto the lug 20, a part of the mounting hole 31 (i.e., the Figure 14 left half part) can be set to be inverted U-shaped, so that the first section 21 and the second section 22 of the lug 20 can be more conveniently inserted into the mounting hole 31 without changing the mounting direction of the damping block 30.

[0068] The damping block 30 further includes grooves 32 provided on both sides of the mounting hole 31. The grooves 32 communicate with the mounting hole 31 and are used to accommodate and snap onto two convex wings 23 on the second section 22 of the lug 20, so as to prevent the damping block 30 from falling off the lug 20.

[0069] Please refer to Figure 13 and Figure 14 , when it is necessary to mount the damping block 30, place the damping block 30 between the first side wall 11 and the second side wall 12 of the holding arm 1, and align the mounting hole 31 of the damping block 30 with the free end of the second section 22 of the lug 20 (i.e., the damping block 30 is located on the Figure 13 right side of the lug 20 as shown), and move the damping block 30 towards the first section 21 of the lug 20 (i.e., move the damping block 30 in the longitudinal direction), so that the lug 20 is inserted therein until the convex wing 23 of the lug 20 is snapped / locked into the groove 32 of the damping block 30, that is, the installation is completed.

[0070] Since the holding arm body 10 is in an elongated shape extending longitudinally, that is to say, the longitudinal dimension between the first side wall 11 and the second side wall 12 is large, and the damping block 30 is mounted onto the lug 20 in the longitudinal direction, the installation space is large and the operation is convenient, effectively improving the defect of inconvenient installation in the Figure 4 shown embodiment.

[0071] Preferably, in one embodiment, the damping block 30 may further be provided with a stopper 34. The stopper 34 is located inside the mounting hole 31 and away from the free end of the second section 22 of the lug 20. When the damping block 30 is mounted onto the lug 20, the stopper 34 is located on the side of the lug 20 away from the free end of the second section 22 to stop the first section 21 of the lug 20, more effectively preventing the damping block 30 from detaching from the lug 20 and enhancing the bonding strength between the two.

[0072] Please refer to Figure 11 , Figure 12 and Figure 14, on the side of the damping block 30 away from the fixed end of the tongue 20 (i.e., the end where the first section 21 is fixed to the first side wall 11), a boss 33 extending towards the top wall 13 can also be provided to prevent the water delivery pipe 4 from falling off the holding arm 1.

[0073] In the above embodiments of the present disclosure, by providing a tongue 20 substantially in an L shape on one side wall of the holding arm 1, wherein the second section 22 of the tongue 20 can extend substantially along the longitudinal direction, and the damping block 30 can be installed on the tongue 20 along this longitudinal direction, the installation is simple and easy, avoiding the problem that the damping block 30 is inconvenient to install due to the small installation space. Moreover, the damping block 30 can cover the lower surface of the tongue 20. Therefore, when the holding arm 1 returns from the maintenance position to the working position, at least a part of the damping block 30 will be clamped between the holding arm 1 and the windshield, buffering the impact of the holding arm main body 10 and preventing the windshield from being damaged.

[0074] Although in the above embodiments of the present disclosure, the damping block 30 is provided with a mounting hole 31, and the tongue 20 is inserted into the damping block 30 for illustration, the present disclosure is not limited thereto. For example, the damping block 30 may not be provided with a mounting hole 30 and is a snap structure that can be snapped onto the tongue 20 from the lower surface of the tongue 20, as long as the damping block 30 can cover the surface of the tongue 20 facing the windshield. Such a setting can more effectively avoid the problem of inconvenient installation caused by the small installation space of the damping block 30.

[0075] In addition, the tongue 20 in the above embodiments of the present disclosure is described with a regular shape (for example, substantially a straight shape or an L shape), but 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 tongue 20 is provided on the bottom side of the holding arm main body 10 close to the windshield and its lower surface is covered with the damping block 30.

[0076] In addition, the above embodiments of the present disclosure mainly describe the design in which the tongue 20 is provided on the holding arm main body 10 and cooperates with the damping block 30, but the present disclosure is not limited thereto. For example, the cooperative design of the tongue 20 and the damping block 30 can also be applied to other vibration / damping and anti-collision occasions.

[0077] In summary, the present disclosure provides a retaining arm for a windshield wiper. By providing a tongue on the bottom side of the retaining arm body close to the windshield and fixing a damping block covering its lower surface (i.e., the surface of the tongue facing the windshield) on the tongue, at least a part of the damping block can be clamped between the retaining arm 1 and the windshield when the retaining arm 1 returns from the maintenance position to the working position, buffering the impact of the retaining arm 1 and preventing the windshield from being damaged. Moreover, convex wings are provided on the opposite edges of the tongue, and grooves for accommodating and clamping the above convex wings are provided on the damping block, so that the damping block can be firmly fixed on the tongue and prevent the damping block from falling off.

[0078] 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.

[0079] The present disclosure also provides a vehicle, which includes the windshield wiper arm 2 described above.
