[0002] Wipers are also often called windshield wipers, windshield wipers, and windshield wipers. They are devices installed on the windshield of vehicles, etc., to remove rain, snow, dust, etc. that obstruct the view of the windshield in case of rain, snow, fog, or dust, so as to ensure driving safety. There are many types of wiper products, which are generally formed by assembling a wiper blade, a drive arm, and some connecting parts. For example, in Figure 1 FIG. 2 shows a scraper blade 200 in an existing scraper and some optional connectors 1, 2, 3, 4, 5 and 6 for matching use. Each of these connectors has a different configuration for matching and installing a corresponding drive arm. For example, when in use, one of the connectors can be selected according to the type of drive arm product configured and used on the current vehicle model (such as a U-shaped hook drive arm, a side locking drive arm, a top locking drive arm or a side pin drive arm, etc.) to replace the one in the scraper blade 200. Figure 1 The figure shows the connector 1 installed on the scraper blade 200, so as to meet more different application requirements. Since there are many types of drive arm products, it is necessary to configure a variety of connectors for matching installation, resulting in a large number of connectors. Utility Model Content

[0048] First of all, it should be explained that the structure, composition, characteristics and advantages of the scraper connector, scraper blade assembly and scraper of the present application will be explained below by way of example, however, all descriptions should not be used to form any limitation on the present application. In this article, the technical term "connection (or engagement)" means that one component is directly and / or indirectly connected (or engaged) to another component, the technical terms "first", "second", etc. are only used for the purpose of distinguishing expressions and are not intended to indicate their order and relative importance, the technical terms "upper", "lower", "right", "left", "top", "bottom", "inner", "outer" and their derivatives, etc. should be linked to the orientation in the drawings, and unless otherwise explicitly stated, the present application can adopt a variety of alternative orientations.

[0049] refer to Figure 3 In this figure, the basic structure of a scraper connecting member 100 according to the present application is roughly shown in an exemplary manner, and it can be installed on, for example, Figure 2 For example, a connector compatible with the scraper connector 100 can be installed on the scraper 200, and then the scraper connector 100 can be installed on the scraper 200 via the connector. The "scraper" described in this article is intended to include such a connector. The drive arm compatible with the scraper connector 100 can be connected to the scraper 200 through the scraper connector 100 to assemble the scraper. As an example, in Figures 5 to 9 The general situation of matching and engaging two top-lock drive arms 300 and 400 having different configurations with the scraper connector 100 is further explained in detail below.

[0050] The scraper connector 100 can be made of plastic, metal or any other suitable material according to application requirements. For example, the scraper connector can be integrally injection molded using plastic, for example, Figure 3 , a gate 160 for use in an injection molding process is exemplarily shown in FIG. 1 , and the gate can be optionally designed to have a concave point structure, which is beneficial to reducing the burr protrusion on the outer surface of the scraper connector.

[0051] like Figure 3As shown, the scraper connector 100 can be constructed to have a first end 110, a second end 120 and a middle portion 130 located therebetween. The first end 110 and the second end 120 are opposite to each other along the length direction of the scraper connector (i.e., the longitudinal direction Y in the figure), and one or more structural features can be optionally provided at appropriate positions on these ends to be used for adaptive engagement with drive arms having different configurations, and the above ends or a portion of their structures can also be covered by a portion of the structure of the drive arm (such as a housing, etc.) after assembly is completed.

[0052] Specifically, a first assembly structure and a second assembly structure can be configured on the first end 110 and the second end 120, so that the first assembly structure can be used to be detachably connected to the driving arm 300 in one or some application scenarios, and the second assembly structure can be used to be detachably connected to the driving arm 400 in another or some application scenarios.

[0053] refer to Figure 4 and Figure 7 As shown in the accompanying drawings, the two drive arms 300 and 400 which are different in configuration are used as examples. Although they are both top-locking drive arms, they have structural differences because they are used in different occasions. For example, the drive arm 300 may have a smaller width than the drive arm 400 (for example, the former has a width of 15 mm, the latter has a width of 19 mm, and so on). Therefore, the prior art needs to configure different connecting parts for each of them separately to realize the assembly connection of the drive arm to the scraper blade 200.

[0054] In contrast, according to the technical solution of the present application, with the aid of the above-mentioned different assembly structures on the scraper connector 100 (for example, the first assembly structure can be configured on the first end 110 and closer to the inside in the transverse direction X than the second assembly structure and the drive arm 300 can be locked in place at the top of the first end 110; for example, the drive arm 400 can be locked in place at the top of the second end 120 through the second assembly structure), the scraper connector 100 can be compatible with matching connections for the drive arm 300 and the drive arm 400, thereby improving the versatility of the connector, reducing the number of accessories for the scraper, and effectively reducing product costs.

[0055] For the first assembly structure, as an example, for example, refer to Figures 3 to 6 As shown, it can be optionally configured to have a locking portion and an engaging portion. Figure 3As shown in FIG. 1 , a groove 141 as an optional configuration may be provided at a position adjacent to the middle portion 130 on the first end portion 110, and a pressure block structure that can be elastically deformed after being subjected to force in the vertical direction Z may be provided in the groove 141, so as to serve as a locking portion 111 that can lock the position of the driving arm 300. That is, such a structure can be used to perform corresponding locking engagement with the assembly portion 310 provided on the driving arm 300 during assembly. For example, the assembly portion 310 can be provided at the end of the driving arm 300 and extend outward to form a snap fit with the locking portion 111 during assembly, so that the end 310 of the driving arm 300 can be locked in place at the top position of the first end portion 110, thereby preventing or reducing the shaking of the driving arm and improving the stability of the device.

[0056] In addition, as an optional situation, the locking portion can also be selectively arranged on the second end 120 to lock the engagement drive arm 300 from the end alone or additionally. As an example, for example, referring to Figures 3 to 6 As shown, the locking portion 125 can be optionally disposed on both sides of the second end portion 120 to be locked with the matching assembly portions 330 located on both sides of the driving arm 300. The assembly portions 330 can be, for example, Figure 4 As shown in the example, the two longitudinal protrusions 123 extend downward from the bottoms 320 on both sides of the driving arm 300, and are configured with a suitable structure that matches and engages with the locking portion 125. More specifically, for example, two longitudinal protrusions 123 can be formed on the second end portion 120, which extend from both sides of the second end portion 120 along the longitudinal direction Y, and a pressing portion 124 is provided at the end of each protrusion. During assembly, a force can be applied to press the two pressing portions 124 so that they are elastically deformed, and then they can be assembled to the driving arm 300, for example Figure 6 In the recessed structure formed between the bottoms 320 on both sides, the locking portions 125 on both sides of the second end portion 120 can be respectively matched and engaged with the assembly portions 330 on both sides of the drive arm 300 by releasing the above-mentioned force, thereby forming a reliable assembly connection. When it is necessary to release the above-mentioned matching and engaging relationship between the drive arm 300 and the scraper connector 100, the pressing portion 124 can be pressed again and the reverse operation can be performed.

[0057] For the joint in the first assembly structure, it can be arranged on the first end 110 and the second end 120, respectively, on one side facing the middle part 130, and on both sides of the middle part 130, for example, it can be constructed to have a contour configuration that matches the corresponding part on the drive arm 300, so that through such a joint, the drive arm 300 can at least be limited from being displaced in the lateral direction X relative to the scraper connector 100 after engagement.

[0058] For example, in Figures 3 to 6 It is shown in an exemplary manner that some sections, such as the first section 113, the second section 114 and the third section 112, can be set on the first end 110, and some other sections, such as the fourth section 122 and the fifth section 127, can be set on the second end 120, and these sections can be used to match and engage with the corresponding parts on the driving arm 300 to achieve the effects of limiting, preventing shaking, etc. Among them, the first section 113 and the fourth section 122 can be set to extend along the vertical direction Z, the second section 114 and the fifth section 127 can be set to extend along the longitudinal direction Y, and the third section 112 can be set to extend along the transverse direction X and be arranged adjacent to the first section 113 and closer to the middle part 130. In this way, when the driving arm 300 is assembled on the scraper connecting member 100, the first section 113 can abut against the two side ends 340 of the driving arm 300, and the second section 114 and the fifth section 127 can abut against the bottom of the driving arm 300. The third section 112 and the fourth section 122 respectively abut against the inner wall (including a part of the inner side wall and a part of the top inner wall) and the inner side wall of the driving arm 300 (for example, the contact surfaces between the third section 112 and the fourth section 122 and the inner side wall of the driving arm 300 can be kept in the same vertical plane, that is, in a plane perpendicular to the transverse direction X), thereby effectively limiting the relative displacement of the driving arm 300. More specifically, for the driving arm 300 that has been installed in place, the first section 113 can limit its displacement in the longitudinal direction Y, the second section 114, the third section 112 and the fifth section 127 can limit its displacement in the vertical direction Z, and the fourth section 122 can limit its displacement in the transverse direction X. In addition, when the above-mentioned joint is combined with the structures discussed above, such as the locking portion 111 and / or the locking portion 125, the drive arm 300 can be more securely fixed in place, effectively limiting the undesirable situations such as shaking and movement relative to the scraper connector 100 after assembly.

[0059] The above provides several specific feasible configurations of the joint portion of the first assembly structure by way of example. It should be understood that the present application allows for more possible configurations, that is, the joint portion can be set at any suitable position on the first end and the second end according to different application requirements, such as the side, top, bottom, etc. The specific shape and configuration can be adapted to the corresponding structure on the drive arm to limit their relative displacement during the use process after assembly, such as allowing the use of left-right symmetrical design, and also allowing the use of asymmetrical design, etc. The above situation is also applicable to various structures for joining or limiting discussed elsewhere in the text, and will not be repeated when introducing them.

[0060] For example, the third section 112 may be optionally configured to have a downwardly curved arc profile, so as to limit the displacement of the driving arm 300 in the transverse direction X, or the third section 112 may be omitted in one or some embodiments. For another example, although the fourth section 122 may be arranged in the example so that its projection toward the first section 113 in the longitudinal direction Y falls into the first section 113, in one or some embodiments, they may be arranged staggered (i.e., the above projection of the fourth section 122 does not overlap with the first section 113), as long as they can be matched and engaged with the corresponding structure on the driving arm 300. Similarly, the top surface of the second section 114 and the top surface of the fifth section 127 may be arranged in the same horizontal plane, and of course, they may be arranged staggered without having to be kept in the same horizontal plane, as long as they can abut the driving arm 300 to limit the displacement in the vertical direction Z, and have the beneficial effects of enhancing the stability of the connection and preventing shaking. In addition, in actual applications, the surfaces of the sections discussed in this article that engage and contact the drive arm can be simple planar structures or other relatively complex structures such as curved surfaces, stepped surfaces, etc., as long as they can be matched and engaged with the corresponding structures on the drive arm, and this application does not impose any restrictions on this.

[0061] The above describes that the first assembly structure on the scraper connector 100 can be used to realize the assembly connection of the drive arm 300. Figure 3 , Figures 7 to 9 The illustrated embodiment continues to introduce the assembly connection of the drive arm 400 by means of the second assembly structure on the scraper connection member 100. Similar to the first assembly structure, the second assembly structure can be configured to have an engaging portion and a locking portion.

[0062] First, as an example, the driving arm 400 can be locked in place on the second end 120 of the scraper connector 100 by the locking portion in the second assembly structure. For example, a locking portion 121 can be provided on the second end 120, such as a groove 126 can be provided at the top position of the second end 120, and one or more protrusions extending upward can be provided in the groove 126, and the protrusions can be elastically deformed after being subjected to force in the vertical direction Z, and can be used as the locking portion 121. For example Figure 7 and Figure 8As shown, when the driving arm 400 is assembled with the scraper connector 100, the protrusion will be elastically deformed after being pressed against the inner wall of the driving arm 400, until it is engaged with a matching structure such as an opening 410 provided on the driving arm 400, and then the protrusion will return to its original position and maintain close contact with the driving arm 400, so that the driving arm 400 can be locked on the top of the second end 120 to prevent the driving arm 400 from shaking during use. It is pointed out that the locking portion 121 does not participate in the locking operation when the driving arm 300 is loaded, and it can maintain or not maintain contact with the inner wall of the driving arm 300 after being installed. When it is designed to maintain the pressing contact in some cases, it can play a certain pressing and limiting role on the driving arm 300.

[0063] In addition, suitable structural features may be provided at other locations on the second end 120, either alone or in addition, to serve as locking portions so as to form a locking engagement with corresponding mounting portion structures on the drive arm 400. For example, the locking portion may be provided by using a locking mechanism such as Figure 3 The structure extending laterally from both sides of the second end 120 as shown in the figure, such as the aforementioned third section 127 or similar structure, can be directly used as the laterally extending structure where the third section 127 in this example is located. Figure 4 The downward portion shown in FIG. 1 is used as a locking portion. Fig. 9 This is indicated by reference numeral 129. When the drive arm 400 is assembled and connected, the locking portion 129 can be correspondingly engaged with the assembly portion 430 (such as a card slot, etc.) provided on the bottom 420 of both sides of the drive arm 400, so as to limit the relative displacement between the drive arm 400 and the scraper connector 100 in the transverse direction X and the vertical direction Z after the engagement. As an optional situation, the length of the assembly portion 430 can be set to be greater than or equal to the length of the locking portion 129, so as to improve the stability of the assembly engagement.

[0064] It should be understood that the present application does not impose any specific restrictions on the structural structure, arrangement position, and configuration quantity of the locking parts in the first assembly structure and the second assembly structure. They can be designed as needed, for example, Figure 3 As shown in FIG. 1 , the protrusion in the locking portion 121 is formed at an inclined angle relative to the longitudinal direction Y so as to facilitate better matching engagement with the corresponding structure on the drive arm.

[0065] The driving arm 400 is also assembled with the scraper connector 100 through the joint in the second assembly structure, so as to help avoid shaking after being fixed in place. The joints can be arranged on the first end 110 and the second end 120, respectively, on one side facing the middle portion 130 and on both sides of the middle portion 130, for example, configured to have a profile configuration that matches and engages with the corresponding part on the driving arm 400, so that the driving arm 400 can at least be limited by the joint to generate relative displacement in the transverse direction X relative to the scraper connector 100 after installation and connection.

[0066] For example, in Figures 7 to 9 As an example, it is shown that the sixth section 115, the seventh section 116 and the eighth section 117 or sections similar thereto can be provided on the first end 110, and the ninth section 128 or sections similar thereto can be provided on the second end 120, so that they can be matched and engaged with the corresponding parts on the driving arm 400 to achieve the effects of limiting, preventing shaking, etc. For the purpose of illustration only, the sixth section 115 can be provided to extend along the vertical direction Z, the seventh section 116 and the ninth section 128 can be provided to extend along the longitudinal direction Y, and the eighth section 117 can be provided to extend along the vertical direction Z and the longitudinal direction Y. As an alternative, the eighth section 117 can be provided as Figure 3 As shown, the side portions of the aforementioned sections 113 and 114 are directly utilized to achieve this, which is beneficial to fully utilizing the structural features of the scraper connecting member 100 and promoting a more compact overall structure.

[0067] In this way, after the driving arm 400 is mounted and connected to the scraper connecting member 100, the sixth section 115 can abut against the two side ends 440 of the driving arm 400, the seventh section 116 can abut against the bottom 420 of the driving arm 400, the eighth section 117 can abut against the inner side wall of the driving arm 400, and the ninth section 128 can abut against the inner side wall of the driving arm 400, so as to effectively limit the relative displacement of the driving arm 400. More specifically, the sixth section 115 can limit the displacement of the driving arm 400 in the longitudinal direction Y, the seventh section 116 can limit the displacement of the driving arm 400 in the vertical direction Z, and the eighth section 117 and the ninth section 128 can limit the displacement of the driving arm 400 in the transverse direction X. Although in the given example, the ninth section 128 and the third section 127 are designed to share a structure extending laterally from both sides of the second end 120, that is, they each use the side and top surfaces of the extension structure to respectively abut against the inner side wall and the bottom of the driving arm 400, which is conducive to forming an overall compact structure; however, in one or some embodiments, the ninth section 128 can be independently configured on the second end 120, for example, it can be arranged on another extension structure that is different from the existing lateral extension structure where the third section 127 is located. In addition, according to different application requirements, the eighth section 117 and the ninth section 128 can be optionally arranged to be located on a common vertical plane parallel to the vertical direction Z, so that the contact surfaces between them and the inner side wall located on the same side of the driving arm 400 can be maintained in the same vertical plane, or they can be arranged on different vertical planes, or even on non-vertical planes with arc-shaped features, as long as they can abut against the corresponding structures on the driving arm 400.

[0068] In addition, when the above-mentioned joints in the second assembly structure are combined with structures such as the locking portion 121 and / or the locking portion 129 discussed above, the drive arm 400 can be more reliably installed in place, effectively limiting problems such as shaking or displacement relative to the scraper connector 100 after assembly.

[0069] In the scraper connecting member 100, the width of the middle portion 130 may be smaller than the width of the first end portion 110 and the width of the second end portion 120, and it may have two side portions opposite to each other, that is, Figure 3The first side portion 131 and the second side portion 132 extending along the longitudinal direction Y of the scraper connecting member are shown in FIG. Among them, the mounting portion 133 can be arranged between the first side portion 131 and the second side portion 132, so as to be used to assemble and connect the scraper connecting member 100 to the scraper blade 200 by means of the mounting portion 133. As an example, for example, the mounting portion 133 can be configured as a groove structure that crosses the above two side portions 131 and 132 and has a bottom opening, so that during assembly, the corresponding assembly structure (such as an axis structure, etc.) arranged on the scraper blade 200 and adapted to the mounting portion 133 can be very conveniently and firmly installed and fixed to the groove structure through the above opening.

[0070] In addition, according to the specific application scenario, a mounting portion 134 can be provided on any one or both of the first side portion 131 and the second side portion 132 for assembly and connection with the scraper blade 200. As an example, the mounting portion 134 can be provided as a protrusion protruding outward from the outer surface of the above-mentioned side portion, and such a protrusion is used to match and engage with the corresponding assembly structure on the scraper blade. With regard to the specific structural structure, number of settings, arrangement position, etc. of such a protrusion, the present application allows flexible design according to the actual application scenario, for example, the protrusion can have an arc section, or multiple protrusions can be arranged in an equidistant or unequally spaced manner, or the protrusion can be arranged at a position adjacent to the end of the above-mentioned opening groove used as the mounting portion 133, or the protrusion can be arranged symmetrically relative to the first side portion 131 and the second side portion 132, etc.

[0071] Continue to refer Figure 3 Some optional configuration structures can be constructed on the scraper connector 100. For example, a cavity 135 can be provided between the first side portion 131 and the second side portion 132 of the middle portion 130, and the cavity can be arranged above the mounting portion 133 in the form of a groove as described above, which can not only save material usage, but also prevent poor appearance caused by shrinkage of the plastic part.

[0072] In addition, as an optional situation, one or more identification parts can be set at any suitable position on the body of the scraper connector 100, such as on any one or more of the first end 110, the second end 120 and the middle part 130 to indicate the characteristic information of the scraper connector 100. Such identification information may include but is not limited to graphics, characters or numbers. For example, Figure 3As shown, a triangular arrow symbol is marked on the top of the first end portion 110 as an identification portion 161, thereby indicating a preset assembly direction for the assembly operation between the scraper connector 100 and the scraper blade 200 and / or the drive arm; for another example, a numerical symbol (such as "2" or other numbers) can be used on the middle portion 130 as an identification portion 162, thereby indicating the number given to the scraper connector in a specific application, thereby facilitating identification and searching during use.

[0073] According to the technical solution of the present application, a scraper blade assembly is also provided, which may include a scraper blade and a scraper connector according to the present application assembled and connected to the scraper blade. The scraper blade assembly may be directly produced and sold as an independent product, so that it is very convenient to assemble the drive arm that meets the application requirements with the scraper blade via the scraper connector. In addition, the scraper blade assembly may be additionally configured with one or more other scraper connectors having different configurations from the scraper connector, that is, the same scraper blade may be used to match more types of drive arms, so that it can fully adapt to different application needs, for example, it can better meet the matching connection requirements of many possible types of drive arms on different models of vehicles.

[0074] For example Figure 3 As shown in FIG. 1 and FIG. 2 , since the present application adopts an optimized structural design for the scraper connector, the scraper connector has the ability to be applicable to more drive arms of different configurations compared to existing products by means of the multiple assembly structures and their locking parts, engaging parts, etc., so as to be compatible with, for example, Figure 1 Compared with the prior art solutions shown, the number of scraper accessories can be effectively reduced, which is very beneficial to the production and manufacturing of the product, improves production efficiency, reduces product costs and facilitates maintenance and use.

[0075] The present application further discloses a scraper, which may include a scraper blade, a driving arm and a scraper connector according to the present application. The scraper connector is assembled to the scraper blade, so that one of the two driving arms with different configurations can be selected to be assembled to the scraper connector according to application needs.
