Description

Technical Field

[0001] This utility model relates to the field of vehicle cleaning, and in particular to a dual-motor windshield wiper mounting structure and vehicle. Background Technology

[0002] As a vibration source in the vehicle, the windshield wiper is subject to rigidity requirements at its mounting point. Higher mounting point rigidity results in less vibration, a smaller sound cavity, lower overall vehicle noise, and better passenger comfort. With increasing vehicle size and larger windshields requiring longer wiper arms, single-motor wipers struggle to meet the power demands of longer arms. This has led to the introduction of dual-motor wipers, which in turn increases the vehicle's excitation source, thus raising the performance requirements for the mounting point. Traditional structures are no longer sufficient to meet the performance demands of dual-motor wipers.

[0003] Traditional windshield wiper mounting structures typically involve welding brackets to the vehicle's frame to provide three mounting points. The wiper bracket structure is cantilevered, and the longer the cantilever, the lower the rigidity. To improve rigidity, the industry usually reduces the cantilever length and increases the thickness of the wiper bracket material in the design. However, even with these improvements, the rigidity of the mounting points often falls short of 1000 N / mm, still failing to meet vehicle NVH targets and thus unable to meet the requirements of dual-motor wiper mounting.

[0038] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0039] In the description of this application, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., used to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a connection within two components or an interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] like Figure 1 , Figure 2 , Figure 5As shown, a first aspect of this application provides a dual-motor windshield wiper mounting structure, including: a side beam assembly 1, an air chamber assembly 2, and a wiper mounting assembly 3. The air chamber assembly 2 is connected to the side beam assembly 1 on both sides along the left-right direction of the vehicle body, and the wiper mounting assembly 3 is provided between the air chamber assembly 2 and the side beam assemblies 1 on both sides. The wiper mounting assembly 3 includes a first bracket 31, a second bracket 32, a third bracket 33, and a fourth bracket 34. The first bracket 31 is mounted on the side beam assembly 1, and the second bracket 32, the third bracket 33, and the fourth bracket 34 are spaced apart on the air chamber assembly 2 along the left-right direction of the vehicle body.

[0042] Based on the above technical solution, the dual-motor wiper mounting structure of this application, by setting a first bracket 31 on the side beam assembly 1 and setting a second bracket 32, a third bracket 33 and a fourth bracket 34 on the air chamber assembly 2, enables the wiper 4 to have a first mounting point on the side, and a second mounting point and a third mounting point at the rear, which, together with the hanging point located in the middle, achieve stable and reliable installation of the dual-motor wiper while maintaining high rigidity performance and meeting the vehicle's NVH target.

[0043] In some embodiments of this application, such as Figures 2-8 and Figure 11 As shown, the first bracket 31, the second bracket 32, and the fourth bracket 34 are all provided with connection holes 35 for locking and connecting with the windshield wiper, and the third bracket 33 is provided with a mounting groove 36 for attaching to the windshield wiper. The connection holes on the first bracket 31, the second bracket 32, and the fourth bracket 34 are aligned with the mounting holes on the windshield wiper 4 and are locked together by fasteners to achieve three-point installation of the windshield wiper 4. The three points form a triangular structure, which makes the installation structure more stable. The middle position of the windshield wiper 4 is inserted into the mounting groove 36 on the third bracket 33 to achieve attachment between the windshield wiper 4 and the third bracket 33, which provides further installation support, thereby achieving four-point installation of the windshield wiper. It should be noted that the connection hole 35 on the first bracket 31 is located at the top of the first bracket 31, the connection holes 35 on the second bracket 32 ​​and the fourth bracket 34 are located at the bottom of the second bracket 32 ​​and the fourth bracket 34, respectively, and the mounting groove 36 on the third bracket 33 is also located at the bottom of the third bracket 33. Furthermore, the second bracket 32, the third bracket 33 and the fourth bracket 34 are all located below the air chamber assembly 2 and are inclined to facilitate the connection of the wiper 4 with the connection hole 35 and the mounting groove 36 on the second bracket 32 ​​and the fourth bracket 34.

[0044] In some embodiments of this application, such as Figures 1-4As shown, the top of the side beam assembly 1 is provided with a first flange 11 extending toward the air chamber assembly 2. The first bracket 31 is obliquely installed between the side of the side beam assembly 1 facing the air chamber assembly 2 and the first flange 11, so as to form a first cavity between the first bracket 31 and the side beam assembly 1. The first flange 11 and the side beam assembly 1 are connected to form a downward-opening gap. The first bracket 31 is obliquely installed in the gap, thereby forming a first cavity between the first bracket 31 and the side beam assembly 1. This cavity can be used to form the lower support of the wiper mounting point, with good structural stability and high rigidity, which can effectively improve the strength and modal characteristics of this mounting point. Specifically, the first flange 31 has mounting holes 111 penetrating its upper and lower sides. The mounting holes 111 are coaxially arranged with the connecting holes 35 of the first bracket 31. When connecting the wiper 4, the fastener passes through the mounting holes 111 and connects with the connecting holes 35 of the first bracket 31.

[0045] Furthermore, in order to improve the connection strength, the first bracket 31 has an upper flange and a lower flange. The upper flange is attached to the lower surface of the first flange 11, and the lower flange is attached to the side of the side beam assembly 1 facing the air chamber assembly 2. The connection hole 35 of the first bracket 31 is provided on the upper flange.

[0046] Specifically, such as Figures 1-4 As shown, the side beam assembly 1 includes an outer side beam plate 12 and an inner side beam plate 13 connected to each other. The inner side beam plate 13 is located on the side of the front side beam assembly 1 facing the air chamber assembly 2. The top of the outer side beam plate 12 and the top of the inner side beam plate 13 are connected to form the first flange 11. The upper end of the first bracket 31 is connected to the first flange 11, and the lower end of the first bracket 31 is connected to the side of the inner side beam plate 13 facing the air chamber assembly 2. The outer side beam plate 12 and the inner side beam plate 13 together constitute the frame of the vehicle body force transmission cavity. The advantage of this is that two plates can be used to replace the solid beam structure, achieving the purpose of weight reduction. The first flange 11 is equivalent to the extension of the connection between the top of the outer side beam plate 12 and the inner side beam plate 13. The windshield wiper can be installed on the first flange 11 with fasteners to fix the first mounting point of the windshield wiper.

[0047] In some embodiments of this application, such as Figure 5As shown, the air chamber assembly 2 includes an air chamber lower plate 21 and a reinforcing beam 22. The edges of the air chamber lower plate 21 and the reinforcing beam 22 are lapped. The air chamber lower plate 21 has a front windshield lapping surface 211 and an assembly vertical surface 212 that are connected in a bent shape. The front windshield lapping surface 211 is connected to the front end of the assembly vertical surface 212. The second bracket 32, the third bracket 33, and the fourth bracket 34 are all installed between the front windshield lapping surface 211 and the assembly vertical surface 212. The air chamber lower plate 21 of the air chamber assembly 2 is installed and connected to the reinforcing beam 22. The reinforcing beam 22 can effectively improve the strength of the air chamber lower plate 21 and avoid deformation or collapse caused by insufficient strength of the multi-stage bent air chamber lower plate 21. Since the front windshield lapping surface 211 and the assembly vertical surface 212 provided on the front side of the air chamber lower plate 21 are in a bent shape, a cavity for installation will be formed at the lower part of the bend of the front windshield lapping surface 211 and the assembly vertical surface 212 for the installation of the second bracket 32, the third bracket 33, and the fourth bracket 34.

[0048] Specifically, as Figure 6 and Figures 8-11 shown, the second bracket 32 includes a first upper bracket 321 and a first lower bracket 322. Both the first upper bracket 321 and the first lower bracket 322 are in a "U" shape, and the top end surfaces of the "U" shapes of the first upper bracket 321 and the first lower bracket 322 are connected at an angle. The bottom end surface of the "U" shape of the first upper bracket 321 is installed on the assembly vertical surface 212, and the bottom end surface of the "U" shape of the first lower bracket 322 is installed on the reinforcing beam 22. The first lower bracket 322 is connected to the first upper bracket 321 to form a wiper installation point.

[0049] The fourth bracket 34 includes a second upper bracket 341 and a second lower bracket 342. Both the second upper bracket 341 and the second lower bracket 342 are in a "U" shape, and the top end faces of the "U" shapes of the second upper bracket 341 and the second lower bracket 342 are angularly connected. The bottom end face of the "U" shape of the second upper bracket 341 is mounted on the overall vertical surface 212, and the bottom end face of the "U" shape of the second lower bracket 342 is mounted on the reinforcing beam 22. The second lower bracket 342 is connected to the second upper bracket 341 to form another mounting point for the wiper. Among them, the second bracket 32 is closer to the side beam assembly 1 than the fourth bracket 34. Since the front windshield overlapping surface 211 and the overall vertical surface 212 are bent and connected, the top end faces of the "U" shapes of the first upper bracket 321 and the first lower bracket 322 need to be angularly connected, so that the front sides of the top end faces of the "U" shapes of the first lower bracket 322 and the second lower bracket 342 are exposed from the front windshield overlapping surface 211. The connection holes 35 are provided at the front side positions of the top end faces of the "U" shapes of the first lower bracket 322 and the second lower bracket 342. The first upper bracket 321 and the second upper bracket 341 are connected to the overall vertical surface 212, the first lower bracket 322 and the second lower bracket 342 are also connected to the reinforcing beam 22, and the first lower bracket 322 is mounted below the first upper bracket 321, and the second lower bracket 342 is mounted below the second upper bracket 342. Therefore, when the dual-motor wiper is installed, the connection points of the first upper bracket and the second upper bracket with the overall vertical surface 212 and the connection points of the first lower bracket and the second lower bracket with the reinforcing beam 22 can both provide reliable fixation for the installation of the dual-motor wiper, enabling the dual-motor wiper to be stably installed on the second bracket 32 and the fourth bracket 34. Specifically, the first and second upper brackets are connected to the overall vertical surface 212 through the bottom end faces of the "U" shapes (i.e., the bottom flanges), and the first and second lower brackets are connected to the reinforcing beam 22 through the bottom end faces of the "U" shapes (i.e., the bottom flanges).

[0050] More specifically, as Figure 6 , Figure 9 , Figure 11As shown, the second bracket 32 ​​further includes a second flange 323, a third flange 324, and a fourth flange 325. The second flange 323 is connected to the upper side of the first upper bracket 321 and extends forward along the front windshield overlap surface 211. The third flange 324 is connected to the lower side of the first upper bracket 321 and extends along the "U"-shaped top end face of the first lower bracket 322. The second flange 323, the "U"-shaped top of the first lower bracket, and the third flange 324 are connected sequentially. The fourth flange 325... The flange 325 is connected to the rear side of the first lower bracket 322 and extends upward along the overall structural surface 212. The second flange 323 is connected to the lower part of the front windshield overlapping surface 211. The third flange 324 is connected to the upper side of the first lower bracket 322. The fourth flange 325 is connected to the front side of the overall structural surface 212. The third flange 324 is used to form a wiper mounting point together with the "U"-shaped top of the first lower bracket 322. The connecting hole 35 of the second bracket 32 ​​is opened on the wiper mounting point.

[0051] The second flange 323 is connected to the top of the first upper bracket 321 and is used to connect below the front windshield overlapping surface 211, so as to achieve a stable connection between the second bracket 32 ​​and the front windshield overlapping surface 211. The third flange 324 is connected to the bottom of the first upper bracket 321 and is used to connect to the "U"-shaped top end face of the first lower bracket 322, so as to achieve a stable connection between the first upper bracket 321 and the first lower bracket 322. The fourth flange 325 is connected to the rear side of the first lower bracket 322 and is used to connect to the front side of the overall vertical surface 212, so as to achieve a stable connection between the second bracket 32 ​​and the overall vertical surface 212. The wiper mounting point formed by the third flange 324 and the first lower bracket 322 is exposed on the front lower side of the front windshield overlapping surface 211 and the overall vertical surface 212. When the wiper is installed, the wiper mounting point can provide support in multiple directions, with a stable structure and good rigidity performance.

[0052] More specifically, such as Figure 8 , Figure 10As shown, the fourth bracket 34 further includes a fifth flange 343, a sixth flange 344 and a seventh flange 345. The fifth flange 343 is connected to the upper side of the second upper bracket 341 and extends left and right along the front windshield overlapping surface 211. The sixth flange 344 is connected to the lower side of the second upper bracket 341 and extends along the "U" - shaped top end surface of the second lower bracket 342. Among them, the fifth flange 343 is connected to the two "U" - shaped side surfaces of the second upper bracket 341, and the sixth flange 344 is connected to the "U" - shaped top of the second upper bracket 241; The seventh flange 345 is connected to the rear side of the second lower bracket 342 and extends upward along the overall vertical surface 212. The fifth flange 343 is connected below the front windshield overlapping surface 211, the sixth flange 344 is connected above the second bracket 32, and the seventh flange 345 is connected to the front side of the overall vertical surface 212. The sixth flange 344 is used to jointly form another wiper mounting point with the "U" - shaped top of the second lower bracket 342, and the connection hole 35 of the fourth bracket 34 is opened at this mounting point.

[0053] The fifth flange 343 is connected to the upper side of the second upper bracket 341 and is used to connect below the front windshield overlapping surface 211 to achieve a stable connection between the fourth bracket 34 and the front windshield overlapping surface 211. The sixth flange 344 is connected to the lower side of the second upper bracket 341 and is used to connect to the "U" - shaped top end surface of the second lower bracket 342 to achieve a stable connection between the second upper bracket 341 and the second lower bracket 342. The seventh flange 345 is connected to the rear side of the second lower bracket 342 and is used to connect to the front side of the overall vertical surface 212 to achieve a stable connection between the fourth bracket 34 and the overall vertical surface 212. The wiper mounting point formed by the sixth flange 344 and the second lower bracket 342 is exposed at the front lower side of the front windshield overlapping surface 211 and the overall vertical surface 212. When installing the wiper at this wiper mounting point, it can provide supporting forces in multiple directions, with stable structure and good stiffness performance. It should be noted that the purpose of the fifth flange 343 extending to the left and right sides is to meet the requirements of the installation space. Since the width of the front windshield overlapping surface 211 may not necessarily ensure that the flange extending forward can be completely connected below the front windshield overlapping surface 211 and may protrude, which can neither ensure the connection strength between the two nor be aesthetically pleasing. At this time, extending the fifth flange 343 to the left and right sides can shorten the length of the fifth flange 343 extending forward, ensure effective support for the front windshield overlapping surface 211, and improve the modal performance of the front windshield overlapping surface 211.

[0054] In addition, the structural forms of the second bracket 32 and the fourth bracket 34 can be replaced according to the actual situation of the front windshield. For example, if the width of the front windshield overlapping surface 211 is relatively wide, then the positions of the second bracket 32 and the fourth bracket 34 in this embodiment can both be adopted as Figure 6 , 9 The structural form of the second bracket 32 in; and when the width of the current windshield lapping surface 211 is relatively narrow, then the positions of the second bracket 32 and the fourth bracket 34 in this embodiment can both adopt the structural form of the fourth bracket 34 as shown in Figure 8 , 10 to ensure the supporting force.

[0055] More specifically, as shown in Figure 6 and Figures 8-10 , eighth flanges 326 are further provided on the left and right sides of the third flange 324, ninth flanges 346 are further provided on the left and right sides of the sixth flange 344, the eighth flanges 326 are connected to the "U"-shaped side surfaces of the first lower bracket 322, and the ninth flanges 346 are connected to the "U"-shaped side surfaces of the second lower bracket 342. The eighth flanges 326 can play a role in strengthening the connection strength between the first upper bracket 321 and the first lower bracket 322. Compared with the connection method only on the top surface of the "U" shape, connecting on the two side vertical surfaces of the "U" shape simultaneously can further improve the structural strength and stability of the second bracket 32; similarly, the ninth flanges 346 install the second upper bracket 341 and the second lower bracket 342 more reliably together, achieving the purpose of improving the structural strength and stability of the fourth bracket 34.

[0056] More specifically, as shown in Figure 6 and Figures 8-11 , a first process through hole 327 penetrating through the first upper bracket 321 is provided on the "U"-shaped top end surface of the first upper bracket 321, and a second process through hole 347 penetrating through the second upper bracket 341 is provided on the "U"-shaped top end surface of the second upper bracket 341. Since the fourth flange 325 and the seventh flange 345 are blocked by the front first upper bracket 321 and second upper bracket 341 when installed on the assembly vertical surface 212, in order to ensure the connection between the first lower bracket 322 and the assembly vertical surface 212, and the connection between the second lower bracket 342 and the assembly vertical surface 212, it is necessary to respectively provide the first process through hole 327 and the second process through hole 347 at the corresponding positions of the first upper bracket 321 and the second upper bracket 341 to facilitate subsequent assembly work.

[0057] In some embodiments of the present application, as shown in Figure 7As shown, the third bracket 33 includes a bracket body 331 and a tenth flange 332 connected to the upper side of the bracket body 331. The bracket body 331 is U-shaped, and the bottom end face of the U-shape of the bracket body 331 is connected to the front side of the overall structural surface 212. The tenth flange 332 is connected to the lower part of the windshield overlap surface 211. The bottom end face of the bracket body 331 is mounted on the overall structural surface 212, and its top end face is inclined upward. The top end face is provided with a mounting groove 36 as a mounting point for windshield wiper installation. The tenth flange 332 can be used to fix and connect with the windshield overlap surface 211, satisfying its own mounting point performance while effectively supporting the front of the windshield and improving the modal performance of the windshield.

[0058] like Figure 1 , Figure 2 As shown, a second aspect of this application provides a vehicle including a vehicle body, a windshield wiper 4, and a dual-motor windshield wiper mounting structure as described above. The side beam assembly 1 and the air chamber assembly 2 are both connected to the front side of the vehicle body. The windshield wiper 4 is connected to the first bracket 31, the second bracket 32, the third bracket 33, and the fourth bracket 34. This vehicle possesses all the features of the aforementioned dual-motor windshield wiper mounting structure and therefore has all the beneficial effects of this structure, which will not be elaborated further here.

[0059] In summary, the dual-motor windshield wiper mounting structure and vehicle of this application, by setting a first bracket 31 on the side beam assembly 1 and setting a second bracket 32, a third bracket 33 and a fourth bracket 34 on the air chamber assembly 2, enables the windshield wiper to have a first mounting point on the side, and a second and a third mounting point at the rear, in conjunction with the attachment point located in the middle, to achieve stable and reliable installation of the dual-motor windshield wiper while maintaining high rigidity performance and meeting the vehicle's NVH targets.

[0060] The above are merely preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
