Description

Technical Field

[0001] This disclosure relates to the field of automotive windshield wiper technology, and more specifically, to a wiper blade holder for holding a wiper blade and a wiper blade assembly including the wiper blade holder. Background Technology

[0002] Car windshield wipers are a key safety component that ensures clear visibility for drivers. They are mainly driven by a wiper motor to drive the wiper arm, and the end of the wiper arm is connected to a wiper blade assembly (also known as a wiper blade or wiper blade) with a rubber blade, which performs a reciprocating wiping motion on the windshield surface.

[0003] A reliable and convenient connection between the wiper blade assembly and the wiper arm is crucial. Currently, various wiper arm interfaces exist on the market, and the width, thickness, locking mechanism position, and shape of the wiper arm connection end can vary significantly between different car manufacturers and even different car models. Traditional wiper blade assemblies are designed primarily for specific wiper arm interfaces. This leads to the following significant drawbacks: a single wiper blade assembly typically only fits one or a few specific wiper arm sizes. The wide variety of car models on the market and the complex and inconsistent wiper arm interface standards make it difficult for wiper blade assemblies to achieve broad compatibility. Therefore, when purchasing or replacing wiper blades, users must first accurately identify their vehicle's wiper arm type and then select the corresponding wiper blade assembly—a complex and error-prone process. Furthermore, ordinary car owners often face difficulties in identifying the interface type and selecting the correct wiper blade assembly when replacing wiper blades themselves. Incorrect wiper blade assembly selection can lead to installation failure, unreliable connection, or even accidental detachment of the wiper blade assembly during wiper operation, posing a safety hazard.

[0004] Therefore, the core problem facing automotive wiper blade assemblies in existing technologies lies in the insufficient universality of their connection structure with the wiper arm, making it impossible to flexibly, reliably, and conveniently adapt to the wide variety of wiper arm interfaces of different sizes on the market. This directly leads to difficulties for users in choosing, inconvenient installation, and potential safety risks.

[0005] Therefore, there is an urgent need in this field for a technical solution to solve the problem of universal connection between wiper blade assembly and wiper arms of various sizes. Utility Model Content

[0006] To address the problems in the prior art, this disclosure proposes an improved scraper support, comprising a support body and scraper legs fixed to the support body for supporting the scraper. The support body includes: two vertical plates spaced apart in a transverse direction, each vertical plate having an upper edge and a lower edge spaced apart in a height direction; and a first horizontal plate and a second horizontal plate connecting the upper edges of the two vertical plates and spaced apart from each other in a longitudinal direction, wherein the upper edge of each vertical plate is offset relative to the first horizontal plate and the second horizontal plate in a height direction between the first horizontal plate and the second horizontal plate to form a notch between the first horizontal plate and the second horizontal plate that is recessed relative to the first horizontal plate and the second horizontal plate.

[0007] According to an alternative embodiment of this disclosure, each vertical plate has an inclined segment in which the distance between the two vertical plates decreases as it approaches the second horizontal plate.

[0008] According to an alternative embodiment of this disclosure, each vertical plate further has an additional inclined segment that decreases the distance between the two vertical plates as it approaches the second horizontal plate, the additional inclined segment being spaced apart from the inclined segment along the longitudinal direction.

[0009] According to an alternative embodiment of this disclosure, the end of the first horizontal plate oriented toward the notch is spaced apart from each vertical plate to form a tongue located between the two vertical plates in the transverse direction, and an opening is formed between the tongue and each vertical plate.

[0010] According to an alternative embodiment of this disclosure, the support body further includes two additional vertical plates connected to the two ends of the tongue opposite in the lateral direction, each additional vertical plate defining a groove extending from a corresponding opening between them.

[0011] According to an alternative embodiment of this disclosure, each additional vertical plate is connected to a corresponding vertical plate at an end remote from the tongue; and / or, the support body further includes a support beam fixed between the two additional vertical plates.

[0012] According to an alternative embodiment of this disclosure, the support body further includes a support plate fixed between the two vertical plates, and the end of each additional vertical plate oriented away from the notch is connected to the support plate.

[0013] According to an alternative embodiment of this disclosure, the support plate is also connected to the first horizontal plate.

[0014] According to an optional embodiment of this disclosure, the first horizontal plate and the two vertical plates define a first channel, the second horizontal plate and the two vertical plates define a second channel, and both the first channel and the second channel extend toward the recess in the longitudinal direction.

[0015] Similarly, in order to address the problems in the prior art described above, this disclosure also proposes an improved wiper blade assembly, comprising: a wiper blade; a wiper blade bracket as described in this disclosure for supporting the wiper blade; and an adapter for engaging with a wiper arm, the adapter being mounted on the wiper blade bracket.

[0016] This disclosure may be embodied in the illustrative embodiments shown in the accompanying drawings. However, it should be noted that the drawings are merely illustrative, and any variations contemplated under the teachings of this disclosure should be considered to be included within the scope of this disclosure.

[0026] Further features and advantages of this disclosure will become more apparent from the following description with reference to the accompanying drawings. Exemplary embodiments of this disclosure are shown in the drawings, and the drawings are not necessarily drawn to scale. However, this disclosure can be implemented in many different forms and should not be construed as necessarily limited to the exemplary embodiments shown herein. Rather, these exemplary embodiments are provided merely to illustrate this disclosure and to convey the spirit and essence of this disclosure to those skilled in the art.

[0027] This disclosure aims to provide an improved wiper blade holder and a wiper blade assembly including the wiper blade holder. Due to its novel design, the wiper blade holder can interface with various types of adapters, allowing it to be connected to various types of wiper arms without requiring a specific wiper blade holder for each type of wiper arm. Therefore, the wiper blade holder according to this disclosure has high versatility due to its novel design. Furthermore, the novel design of the wiper blade holder according to this disclosure also avoids structural interference with various types of wiper arms, enabling the wiper blade holder to reliably swing with the wiper arm after being connected to various types of wiper arms via adapters. This allows the wiper blade mounted on the wiper blade holder to accurately perform the wiping action, providing the driver with a clear view. In particular, the novel design of the wiper blade holder according to this disclosure also allows it to reliably receive the oscillating force applied by the wiper arm via the adapter, which also allows the wiper blade to accurately swing with the wiper arm, thereby accurately performing the wiping action. In particular, the novel design of the scraper bracket according to this disclosure also allows it to be easily connected and disconnected from various adapters, which enables ordinary users to easily replace the adapters on the scraper bracket without the need for professional personnel to perform the replacement operation.

[0028] The following describes in detail, with reference to the accompanying drawings, alternative but non-limiting embodiments of the scraper support and scraper assembly according to this disclosure. It should be noted that although the various views show the height direction HH', longitudinal direction LL', and lateral direction TT', which are generally perpendicular to each other (i.e., generally transverse to each other), and embodiments of this disclosure will be described with reference to these three directions, this is merely intended to convey the teachings of this disclosure more intuitively with reference to the accompanying drawings, and not to limit the scope of protection of this disclosure in any way. For example, in practical applications, the height direction HH' may not coincide with the vertical direction.

[0029] refer to Figure 1 The illustration shows a schematic perspective view of a wiper blade assembly according to one embodiment of the present disclosure, connected to a wiper arm. Figure 1As shown, the wiper blade assembly includes a wiper blade (e.g., made of synthetic rubber) 100, a wiper blade bracket (e.g., made of engineering plastic) 200 supporting the wiper blade 100, and an adapter (e.g., made of engineering plastic) 300 mounted on the wiper blade bracket 200, wherein the wiper blade 100 and the adapter 300 are located on opposite sides of the wiper blade bracket 200. Additionally, the adapter 300 is connected to the wiper arm 20 so that the adapter 300, along with the wiper blade bracket 200 and the wiper blade 100, can swing with the wiper arm 20. When the wiper arm 20 positions the wiper blade 100 against the windshield, the wiper blade 100 can swing to clear rainwater from the windshield, thereby providing the driver with a clear view. As described in detail below, the wiper blade bracket 200 can interface with various types of adapters 300, thus allowing it to be connected to various types of wiper arms 20, giving the wiper blade bracket 20 a high degree of versatility.

[0030] refer to Figure 2 and Figure 3 ,in, Figure 2 It shows Figure 1 A schematic perspective view of the scraper support of the scraper assembly shown, and Figure 3 It shows along Figure 2 A schematic cross-sectional view of the scraper support taken from line III-III in the diagram. (See attached image.) Figure 2 and Figure 3 As shown, the wiper blade bracket 200 includes a bracket body 210 and wiper blade legs 220 (two shown in the figure) fixed to the bracket body 210. An adapter 300 can be mounted on the bracket body 210, and the wiper blade legs 220 can support the wiper blade 100, for example, by clamping, so that the wiper blade 100, the wiper blade bracket 200 and the adapter 300 can be combined together. When the adapter 300 is connected to the wiper arm 20, the wiper arm 20 can drive the wiper blade 100 to swing on the windshield of the car through the adapter 300 and the wiper blade bracket 200 to clear rainwater from the windshield and thus provide the driver with a clear view.

[0031] like Figure 2 and Figure 3As shown, the support body 210 includes two vertical plates 211 spaced apart from each other along the lateral direction TT', wherein each vertical plate 211 has an upper edge 211a and a lower edge 211b spaced apart from each other along the height direction HH' (i.e., opposite to each other along the height direction HH'). In addition, the support body 210 also includes a first horizontal plate 212 and a second horizontal plate 213 that connect the upper edges 211a of the two vertical plates 211 to each other. The first horizontal plate 212 and the second horizontal plate 213 are spaced apart from each other along the longitudinal direction LL'. That is, the first horizontal plate 212 and the second horizontal plate 213 connect the upper edges 211a of the two vertical plates 211 to each other at two positions spaced apart from each other along the longitudinal direction LL'. Since the first horizontal plate 212 and the second horizontal plate 213 are spaced apart from each other along the longitudinal direction LL', a notch 201 for receiving the adapter 300 is left between the first horizontal plate 212 and the second horizontal plate 213. The notch 201 is defined in the transverse direction TT' between the two vertical plates 211 (more specifically, the upper edges 211a of the two vertical plates 211). Specifically, the upper edge 211a of each vertical plate 211 is offset along the height direction HH' between the first horizontal plate 212 and the second horizontal plate 213 in a direction away from the first horizontal plate 212 and the second horizontal plate 213 (i.e., closer to the lower edge 211b), so that the notch 201 is recessed relative to the first horizontal plate 212 and the second horizontal plate 213 in the height direction HH', thereby making (ideally as) Figure 3As shown, the first channel 214, defined by the first horizontal plate 212 and the two vertical plates 211, and the second channel 215, defined by the second horizontal plate 213 and the two vertical plates 211, can both lead to the recess 201 along the longitudinal direction LL'. In the above configuration, as described in more detail below, after the adapter 300 is placed in the recess 201, both the first channel 214 and the second channel 215 can be used to receive the mating structure of the adapter 300, thereby holding the adapter 300 in the recess 201. Specifically, each vertical plate 211 has an inclined segment 211c extending obliquely relative to the lateral direction TT' and the longitudinal direction LL', which decreases the distance between the two vertical plates 211 in the lateral direction TT' as it moves away from the first horizontal plate 212 (i.e., as it moves closer to the second horizontal plate 213). That is, by means of the inclined segment 211c, the two vertical plates 211 move closer to each other as they approach the second horizontal plate 213. In this configuration, the lateral width of the bracket body 210 can decrease as it approaches the second horizontal plate 213, thereby helping to avoid structural interference between the bracket body 210 and the wiper arm 20. This allows the wiper bracket 200 to accommodate wiper arms 20 of more sizes, thus further improving the versatility of the wiper bracket 200. More specifically, each vertical plate 211 also has an additional inclined segment 211d that extends obliquely relative to the lateral direction TT' and the longitudinal direction LL'. This additional inclined segment 211d is spaced apart from the inclined segment 211c along the longitudinal direction LL', and similarly, the distance between the two vertical plates 211 in the lateral direction TT' decreases as they move away from the first horizontal plate 212 (i.e., as they approach the second horizontal plate 213). Therefore, the additional inclined segment 211d also helps to reduce the width of the bracket body 210, thereby avoiding structural interference between the bracket body 210 and the wiper arm 20, thus further improving the versatility of the wiper bracket 200.

[0032] like Figure 2 As shown, optimally as Figure 2As shown in the enlarged view, the end of the first horizontal plate 212 oriented toward the notch 201 (that is, toward the second horizontal plate 213) is spaced apart from the two vertical plates 211 on both sides along the lateral direction TT' to form a tongue 212a located between the two vertical plates 211 in the lateral direction TT'. Since the tongue 212a is spaced apart from the two vertical plates 211 along the lateral direction TT', an opening 212b is formed between the tongue 212a and each vertical plate 211. That is, two openings 212b are formed on opposite sides of the tongue 212a along the lateral direction TT'. Specifically, the support body 210 also includes two additional vertical plates 216 connected to the two ends opposite to the transverse direction TT' of the tongue 212a. These two additional vertical plates 216 are also spaced apart from the two vertical plates 211 on both sides along the transverse direction TT', such that a groove 212c extending the opening 211b toward the lower edge 211b of the vertical plate 211 is formed between each additional vertical plate 216 and the corresponding vertical plate 211. That is, not only are two openings 212b formed on the opposite sides of the tongue 212a along the transverse direction TT', but also two grooves 212c are formed on the opposite sides of the tongue 212a along the transverse direction TT' through the two additional vertical plates 216. Each groove 212c extends from the corresponding opening 212b toward the direction away from the upper edge 211a of the vertical plate 211 (i.e., near the lower edge 211b of the vertical plate 211). With the above configuration, as described in more detail below, the adapter 300 can more easily and quickly dock and detach from the support body 210 by means of the two openings 212b and the two grooves 212c, and the adapter 300 can more reliably transmit the swing force to the support body 210. In particular, each additional vertical plate 216 is connected to the corresponding vertical plate 211 at the end away from the tongue 212a, such that each groove 212c does not extend through the support body 210 along the height direction HH', but extends from the corresponding opening 212b along the height direction HH' and terminates at the end of the corresponding additional vertical plate 216 away from the tongue 212a. In this configuration, the two additional vertical plates 216 not only define the groove 212c, but also support the tongue 212a in the height direction HH' and the lateral direction TT', thereby limiting the deformation of the tongue 212a in the height direction HH' and the lateral direction TT', thus preventing damage or even breakage of the tongue 212a due to excessive deformation in the height direction HH' and the lateral direction TT'. Therefore, the above configuration improves the structural strength of the support body 210 and helps to extend its service life.

[0033] like Figure 2 The enlarged view in the middle and Figure 3As shown in the enlarged view, the bracket body 210 also includes a support beam 217 fixed between two additional vertical plates 216. Specifically, the support beam 217 is oriented in the lateral direction TT' and its two ends are respectively connected to the two additional vertical plates 216. In this configuration, since the support beam 217 is supported between the two additional vertical plates 216, it can limit the deformation of the two additional vertical plates 216 in the lateral direction TT', thereby further improving the structural strength of the bracket body 210. This allows the wiper blade bracket 200 to more reliably withstand the oscillating force transmitted from the adapter 300, enabling the wiper blade 100 to perform wiper actions more accurately, as described in more detail below. In particular, the bracket body 210 also includes a support plate 218 fixed between two vertical plates 211, meaning that the two ends of the support plate 218 are respectively connected to the two vertical plates 211. Furthermore, the support plate 218 is located at a position spaced apart from the notch 201 along the longitudinal direction LL', that is, the support plate 218 is located in the first channel 214 defined by the first horizontal plate 212 and the two vertical plates 211. Additionally, the ends of each additional vertical plate 216 oriented away from the notch 201 are connected to the support plate 218. Specifically, the support plate 218 is also connected to the first horizontal plate 212. In this configuration, the support plate 218 can further limit the deformation of the tongue 212a in the height direction HH' and the lateral direction TT', and can also further limit the deformation of the two additional vertical plates 216 in the lateral direction TT', thereby further improving the structural strength of the support body 210.

[0034] refer to Figure 4 , which shows Figure 1 A schematic perspective view of the adapter for the scraper assembly shown. Figure 4As shown, the adapter 300 includes an adapter body 310 and spring arms 320 and positioning protrusions 330 disposed at both ends of the adapter body 310 that are spaced apart along the longitudinal direction LL' (i.e., opposite along the longitudinal direction LL'). Additionally, the adapter body 310 also has two guide protrusions 311 protruding along the longitudinal direction LL', located on opposite sides of the spring arms 320 along the transverse direction TT'; in other words, the spring arms 320 are positioned between the two guide protrusions 311 in the transverse direction TT'. Specifically, the adapter body 310 also has two ramps 312 on its surface that are opposite along the transverse direction TT', and these ramps 312 are configured to reduce the size (also referred to as the transverse width) of the adapter body 310 in the transverse direction TT' as it approaches the positioning protrusions 330. Additionally, the spring arm 320 has a fixed end 321 connected to the adapter body 310 and a free end 322 spaced apart from the adapter body 310 along the longitudinal direction LL'. The elastic deformation of the spring arm 320 allows the free end 322 to move between an unlocked position close to the adapter body 310 and a locked position away from the adapter body 310, and the spring arm 320 is adapted to generate a restoring force that biases the free end 322 toward the locked position. In other words, the spring arm 320 has a normal state in which the free end 322 is in the locked position away from the adapter body 310 and a compressed state in which the free end 322 is in the unlocked position close to the adapter body 310, and the elastic deformation of the spring arm 320 generates a restoring force that biases the free end 322 toward the locked position. In this configuration, the user can apply a pushing force to the free end 322 of the spring arm 320 to cause elastic deformation, thereby pushing the free end 322 to the unlocked position. The spring arm 320 can automatically return to the locked position after the pushing force is removed, thus allowing the adapter 300 to be mounted on and removed from the scraper bracket 200 as described in detail below. Specifically, for ease of user operation, the free end 322 of the spring arm 320 forms a handle adapted to engage the user's fingers, allowing the user to push the free end 322 to the unlocked position by pressing the handle. Specifically, a portion of the surface of the spring arm 320 facing away from the adapter body 310 (i.e., facing away from the adapter body 310) forms an engagement groove 323 extending in the lateral direction TT', and another portion of this surface forms a ramp 324 that slopes away from the adapter body 310 as it approaches the engagement groove 323. More specifically, the engagement slot 323 is positioned adjacent to the free end 322, that is, the engagement slot 323 is positioned between the free end 322 and the ramp 324. As described in more detail below, this configuration facilitates the mounting of the adapter 300 onto the scraper bracket 200.In addition, as described in more detail below, the positioning protrusion 330 and the two guide protrusions 311 make it easier to install the adapter 300 on the wiper blade bracket 200 and remove the adapter 300 from the wiper blade bracket 200. The positioning protrusion 330 and the two guide protrusions 311 also help to transmit the oscillating force applied by the wiper arm 20 in the lateral direction TT' to the wiper blade bracket 200.

[0035] Specifically, refer to Figure 5 and Figure 6 ,in, Figure 5 It shows Figure 1 The diagram shows a schematic perspective view of the wiper assembly in which the adapter and wiper bracket are joined. Figure 6 It shows Figure 1 The diagram shows a schematic cross-sectional view of the wiper blade assembly, in which the adapter and wiper blade bracket are fully engaged. Figure 5 As shown, if the adapter 300 needs to be installed on the scraper bracket 200, the positioning protrusion 330 of the adapter 300 can first be inserted into the second channel 215 of the bracket body 210. Then, the adapter 300 is rotated until the ramp 324 of the spring arm 320 abuts against the tongue 212a of the bracket body 210. If the adapter 300 is pressed towards the bracket body 210, the tongue 212a will bias the free end 322 of the spring arm 320 toward the unlocked position with the aid of the ramp 324, until the tongue 212a enters the engaging groove 323 on the spring arm 320. As the tongue 212a enters the engaging groove 323, the elastic restoring force of the spring arm 320 can bias the free end 322 back to the locked position, thereby making the tongue 212a engaged in the engaging groove 323, and the spring arm 320 is partially received in the first channel 214, thus allowing the adapter 300 to be installed on the bracket body 210. Figure 6As shown, after the adapter 300 is installed onto the scraper bracket 200, the tab 212a of the bracket body 210 prevents the spring arm 320 of the adapter 300 from disengaging from the bracket body 210, and the second transverse plate 213 of the bracket body 210 prevents the positioning protrusion 330 of the adapter 300 from disengaging from the bracket body 210. That is, the adapter 300 engages with the bracket body 210 on opposite sides along the longitudinal direction LL', thereby reliably holding the adapter 300 on the bracket body 210. It is also worth mentioning that during the above installation, each guide protrusion 311 of the adapter 300 will enter the corresponding groove 212c through the corresponding opening 212b of the bracket body 210 and will be clamped between the corresponding vertical plate 211 and the additional vertical plate 216 of the bracket body 210. In this configuration, the two guide protrusions 311 not only guide the adapter 300 during installation to ensure accurate mounting on the bracket body 210, but also reliably hold the spring arm 320 between the two additional vertical plates 216 after the adapter 300 is installed, transmitting the oscillating force applied by the wiper arm 20 to the bracket body 210. This prevents the spring arm 320 from interacting with the two additional vertical plates 216 in the lateral direction TT', thus preventing breakage due to excessive deformation in the lateral direction TT'. Specifically, after the adapter 300 is installed, the positioning protrusion 330 abuts against the second horizontal plate 213 of the bracket body 210 and is clamped between the two vertical plates 211. Therefore, the positioning protrusion 330 can also transmit the oscillating force applied by the wiper arm 20 to the bracket body 210, thereby enabling the wiper arm 20 to drive the wiper blade bracket 200 more reliably via the adapter 300. If it is necessary to remove the adapter 300 from the scraper bracket 200, the user only needs to push the free end 322 of the spring arm 320 to the unlocked position and perform the reverse steps of the installation operation described above to easily remove the adapter 300 from the scraper bracket 200. Therefore, the scraper bracket 200 according to this disclosure allows ordinary users to easily install and remove the adapter 300 without the need for professional operation. Specifically, as... Figure 5 As shown, after the adapter 300 is installed on the wiper arm bracket 200, the inclined sections 211c of the two vertical plates 211 of the bracket body 210 of the wiper arm bracket 200 are aligned with the two ramps 312 of the adapter body 310 of the adapter 300 in the height direction HH'. With this configuration, structural interference between the assembled wiper arm bracket 200 and adapter 300 and the wiper arm 20 can be avoided, allowing it to be connected to more models of wiper arms 20, thereby further improving the versatility of the wiper arm bracket 200.

[0036] It is also worth mentioning that, as mentioned above, after the adapter 300 is installed on the bracket body 210 of the scraper bracket 200, the spring arms 320 and positioning protrusions 330 at both ends of the adapter 300 are received in the first channel 214 and the second channel 215 located on both sides of the notch 201 of the bracket body 210. Therefore, the bracket body 210 only needs to cooperate with the spring arms 320 and positioning protrusions 330 at both ends of the adapter 300 to reliably hold the adapter 300 on the bracket body 210. There are no requirements regarding the shape and / or construction of the adapter 300 between the spring arms 320 and the positioning protrusions 330. This allows various models of adapters 300, which have spring arms 320 and positioning protrusions 330 at both ends but different shapes and / or constructions between them, to be installed and reliably held on the bracket body 210 of the wiper blade bracket 20. Furthermore, the wiper blade bracket 200 can be connected to various models of wiper arms 20 via various models of adapters 300. Therefore, the wiper blade bracket 200 according to this disclosure has high connectivity versatility. For example, refer to... Figure 7 and Figure 8 ,in, Figure 7 A schematic perspective view of a wiper blade assembly according to another embodiment of the present disclosure, connected to another wiper arm, is shown. Figure 8 A schematic perspective view is shown of a wiper blade assembly according to yet another embodiment of the present disclosure, connected to yet another type of wiper arm. Figure 1 , Figure 7 and Figure 8 In the three embodiments shown, the wiper blade assembly has the same wiper blade bracket 200 and different adapters 300, and the different adapters 300 can be installed on the same wiper blade bracket 200, so that the wiper blade assembly can be connected to different wiper arms 20 by simply replacing the different adapters 300, without replacing the wiper blade bracket 200, thereby giving the wiper blade assembly a high degree of connection versatility.

[0037] The foregoing has described in detail, with reference to the accompanying drawings, optional but non-limiting embodiments of the scraper support and scraper assembly according to this disclosure. Modifications and additions to the technology and structure, as well as recombinations of features in the various embodiments, will be readily apparent to those skilled in the art without departing from the spirit and essence of this disclosure and should be considered within its scope. Therefore, all such modifications and additions conceivable under the teachings of this disclosure should be considered part of this disclosure. The scope of this disclosure includes equivalent technologies known at the filing date of this disclosure and equivalent technologies not yet foreseen.
