Abstract
Description
Technical Field
[0001] This disclosure relates to a rear wiper and a vehicle including the rear wiper, and more particularly to a connection device for a washer-spray rear wiper. Background Technology
[0002] The rear windshield wiper of a vehicle reciprocates against the rear windshield during wiping operations to remove rainwater, dust, and other debris. Typically, a rear windshield wiper includes an arm mount, a wiper arm, and a wiper blade connected in sequence. A first connecting portion of the wiper arm is pivotally connected to the arm mount, and a second connecting portion of the wiper arm is connected to the wiper blade. The wiper blade rests against the rear windshield and is driven to reciprocate, performing the wiping operation.
[0003] However, ordinary rear wipers sometimes cannot clean effectively, and water-spray wipers are needed to achieve better cleaning results. Therefore, different types of connectors are required to connect to the water hose to match the different angles of the wiper arms. However, different types of connectors increase the design and production costs.
[0004] Therefore, those skilled in the art are dedicated to developing a novel connection device to overcome the aforementioned deficiencies of the prior art. Summary of the Invention
[0005] The purpose of this disclosure is to provide a connecting device with flexible ends that can meet different angle requirements, thereby reducing design, manufacturing, and installation costs.
[0006] This disclosure provides a connecting device designed for installation on the rear windshield wiper of a vehicle and for conveying fluid. The connecting unit includes a first component and a second component, both of which are hollow structures to form a fluid channel. A first end of the first component is connected to the output shaft of a wiper motor, and a second end of the first component is connected to the first end of the second component. The first end of the second component is connected to the second end of the first component, and the second end of the second component is connected to a water pipe. The second component has a generally L-shaped structure, with the extension directions of the first and second ends being approximately perpendicular. The angle of the second end of the second component relative to the second end of the first component is adjustable.
[0007] This disclosure improves the adaptability of the connection device and reduces costs by disassembling the connection device into different components, making it compatible with water pipes arranged at different angles.
[0008] In one or more embodiments, the second end of the first component has an opening, and the first end of the second component is inserted into the opening at the second end of the first component.
[0009] In one or more embodiments, a protrusion is formed on a second end of the first component, the protrusion extending from the length of the second end and radially along the second end.
[0010] In one or more embodiments, the first end of the second component has an annular structure on its outer peripheral surface, the annular structure having a notch.
[0011] In one or more embodiments, in the assembled state, the annular structure is located between the second end and the protrusion.
[0012] During installation, align the notch on the annular structure with the protrusion on the second end of the first component, insert the first end of the second component into the opening on the second end of the first component, and then rotate the second component to adjust it to the appropriate angle. At the same time, the protrusion on the second end of the first component can also prevent the second component from coming out.
[0013] In one or more embodiments, the notch is formed on one side corresponding to the second end of the second component.
[0014] In one or more embodiments, the connecting device further includes a third component, which is a sealing ring located between the first component and the second component.
[0015] In one or more embodiments, a groove is formed on the second end of the second component, and the third component is accommodated in the groove.
[0016] This disclosure ensures sealing by providing a sealing ring between the first and second components, while also increasing friction to prevent undesirable relative rotation between the first and second components.
[0017] This disclosure, through the design of the connecting device, has a flexible end that can meet the requirements of different angles, thereby reducing the costs of design, production, and installation.
[0018] This disclosure also provides a rear wiper that includes the aforementioned connecting device.

[0027] The following specific embodiments illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification.
[0028] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art in understanding and reading the content disclosed herein, and are not intended to limit the implementation conditions of this disclosure. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effectiveness and purpose of this disclosure, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "above" and "a" used in this specification are merely for clarity of description and are not intended to limit the scope of this disclosure. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this disclosure's implementation.
[0029] To better understand this disclosure, the various embodiments of this disclosure are described below in conjunction with the accompanying drawings.
[0030] Figure 1 and Figure 2 A rear windshield wiper 100 for a motor vehicle is shown in a perspective view. As shown, the rear windshield wiper 1 includes an arm mount 1, a wiper arm 2, and a wiper blade 3 connected in sequence.
[0031] In one specific embodiment, the wiper arm 2 has an elongated shape extending in a longitudinal direction, wherein the longitudinal direction is the length direction of the wiper arm 2, and the transverse direction, perpendicular to the longitudinal direction, is the width direction of the wiper arm 2. One end of the wiper arm 2 is connected to the arm base 1, and the other end is connected to the wiper blade 3 that abuts against the rear windshield.
[0032] When the rear wiper 100 is installed on a vehicle, one end of the arm mount 1 is connected to a drive mechanism (not shown), which may be, for example, a drive motor and / or linkage mechanism installed in the vehicle, and the arm mount 1 is rotatably fixed to the output shaft 20 of the drive motor and / or linkage mechanism so as to be driven and perform reciprocating motion.
[0033] For a water-spraying rear wiper, a fluid channel is required to transport liquid from a storage container to the wiper blade 3. Typically, the liquid storage container is located inside the vehicle body, and the liquid is transported to the outside of the vehicle body via a channel within the output shaft 20 of the drive motor and / or linkage mechanism, and then guided to the wiper blade via a hose. The connection device 10 according to this application is particularly suitable for water-spraying rear wipers, providing a connection between the output shaft 20 and the water hose 30.
[0034] like Figure 3 and 4 As shown, the connecting device 10 includes a first component 11 and a second component 12. Both the first component and the second component are hollow structures to form a fluid channel. The first end 111 of the first component 11 is connected to the output shaft 20 of the wiper motor, and the second end 112 of the first component 11 is connected to the first end 121 of the second component 12. The first end 121 of the second component 12 is connected to the second end 112 of the first component 11, and the second end 122 of the second component 12 is connected to the water pipe 30. The angle of the second end 122 of the second component 12 is adjustable relative to the first end 111 of the first component 11.
[0035] Since the connecting device of this application includes a first component 11 and a second component 12, the relative angle between the first component 11 and the second component 12 can be adjusted to adapt to different water pipe routes, thereby improving flexibility.
[0036] like Figure 3-7 As shown, the second component 12 has a generally L-shaped structure, with the extension direction of the first end 121 and the extension direction of the second end 122 being approximately perpendicular. This arrangement allows for high adaptability. The first component 11 can also have a generally L-shaped structure, with the extension direction of the first end 111 and the extension direction of the second end 112 being approximately perpendicular, thereby further increasing adaptability.
[0037] like Figure 3 and 5 As shown, the second end 112 of the first component 11 has an opening 113, and the first end 121 of the second component 12 is inserted into the opening 113 of the second end 112 of the first component 11.
[0038] like Figure 3 and 4As shown, a protrusion 114 is formed on the second end portion 112 of the first component 11. The protrusion 114 extends from the length direction of the second end portion 112 and extends radially along the second end portion 112. Figure 3 As shown, there is a certain distance or gap between the protrusion 114 and the end face of the second end 112. The protrusion 114 is integrally formed with the first component 11. The protrusion 114 is used to prevent the first component 11 and the second component 12 from separating after they are assembled.
[0039] like Figure 3 and 4 As shown, the first end 121 of the second component 12 has an annular structure 123 on its outer peripheral surface. The annular structure 123 is formed on the outer peripheral surface of the first end 121 of the second component 12, and its diameter is larger than the diameter of the opening 113. When the first end 121 is inserted into the opening 113 of the second end 112 of the first component 11, the annular structure 123 can act as a limiting device. The annular structure 123 is integrally formed with the second component 12.
[0040] In one example, the annular structure 123 has a notch 124. The size of the notch 124 is slightly larger than the size of the protrusion 114. The notch 124 facilitates the assembly of the first component 11 and the second component 12.
[0041] like Figure 5 and 6 As shown, during assembly, when the first end 121 of the second component 12 is inserted into the opening of the second end 112 of the first component 11, the notch 124 on the annular structure 123 is aligned with the protrusion 114 formed at the second end of the first component 11. After insertion into the appropriate position, the annular structure 123 reaches the gap between the protrusion 114 and the end face of the second end 112. Then, according to the arrangement requirements of the water pipe 30, the second end 121 of the second component 12 is rotated until it reaches the appropriate position, such as... Figure 7 As shown. After rotation, the position corresponding to the protrusion 114 will be the non-notch 124 part of the annular structure 123. Figure 7 Only one example of the assembled state is shown. The second end 121 of the second component 12 can be rotated to any suitable angle as needed. This design prevents the second component 12 from disengaging from the connection state with the first component 11, ensuring the reliability of the connecting device 10.
[0042] In the assembled state, the annular structure 123 is located between the second end 112 and the protrusion 114. The protrusion 114 is disposed at a certain distance from the end face of the second end 112 in the extending direction of the second end 112. This distance is slightly greater than the thickness of the annular structure 123 to accommodate the annular structure 123 while ensuring a limiting effect.
[0043] In one example, the notch 124 is formed on the side corresponding to the second end 122 of the second component 12. In other words, the opening direction of the notch 124 is the same as the extension direction of the second end 122 of the second component 12. This arrangement can ensure the assembly effect while allowing the connecting device 10 to adapt to more application scenarios.
[0044] Both the first component 11 and the second component 12 are molded from plastic material, which advantageously saves costs and is suitable for mass production.
[0045] like Figure 4 As shown, the connecting device 10 also includes a third component 13, which is a sealing ring located between the first component 11 and the second component 12. The sealing ring can improve the sealing performance required for the fluid transport of the connecting device 10. Furthermore, the sealing ring can enhance friction to a certain extent, so that when the second component 12 of the connecting device is adjusted to an appropriate angle relative to the first component 11, this angle can be maintained without applying additional force, preventing undesirable rotation and thus improving the stability and service life of the windshield wiper. The sealing ring can be made of flexible materials such as rubber.
[0046] Specifically, a groove 125 is formed on the second end 121 of the second component 12, and the third component 13 is accommodated in the groove 125. This arrangement ensures that the third component has a definite installation position, is not prone to displacement, and reduces the difficulty of assembly.
[0047] During the assembly process, such as Figure 5 As shown, preferably, the third component 13 is first assembled into the groove 125 on the second end 121 of the second component 12, and then the second component 12 and the first component 11 are assembled.
[0048] This disclosure, through the design of the connecting device, has a flexible end that can meet the requirements of different angles, thereby reducing the costs of design, production, and installation.
[0049] This application also provides a rear wiper including the aforementioned connecting device. The rear wiper has all the advantages of the aforementioned connecting device.
[0050] This disclosure also provides a vehicle including the aforementioned rear windshield wiper.
[0051] The foregoing description, with reference to preferred embodiments, illustrates exemplary implementations of the connection device, rear wiper, and vehicle provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
