The fracture guide guides the connector to fracture after the impact force on the connector reaches a threshold, so that the first connecting part and the second connecting part are separated or the first connecting part is displaced relative to the second connecting part. In this way, the first mounting seat connected to the first connecting part and the second mounting seat connected to the second connecting part are separated from each other or are displaced relative to each other. This causes the first mounting seat to sink due to the inertia of the impact load. As a result, the height of the first mounting seat protruding from the hood is reduced. This sinking design helps to reduce the injury to the head of pedestrians.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] As a protruding component, the windshield wiper mount presents a significant risk of head injury during a collision. The pedestrian, thrown against the hood by inertia, is likely to have their head directly impact the mount. Furthermore, the impact can cause the pedestrian to bounce upwards, potentially resulting in a secondary head collision with the wiper mount and causing serious head injuries.

[0048] In view of this, according to a first aspect of this application, embodiments of this application provide a connector 400, a wiper assembly 1000, and a vehicle to reduce the risk of head injury to pedestrians from the wiper assembly 1000. The connector 400 is suitable for use in the wiper assembly 1000 of a vehicle. The connector 400 can be used for either the main wiper or the auxiliary wiper. (See reference...) Figures 1 to 4This describes the structure related to the wiper assembly 1000 to which the connector 400 is applicable. Exemplarily, the wiper assembly 1000 includes a first mounting base 100, a second mounting base 200, a wiper blade 300, and a motor 500. The second mounting base 200 is fixed to the vehicle body sheet metal. The wiper blade 300 is mounted on the first mounting base 100. The first mounting base 100 has a rotating shaft 110 connecting to the wiper blade 300. The bottom of the rotating shaft 110 is connected to the motor 500, which drives the rotating shaft 110 to rotate, thereby driving the wiper blade 300 to operate. One end of the first mounting base 100 is connected to the second mounting base 200 via the connector 400, thereby fixing it to the vehicle body. The other end is connected to the motor 500, forming a stable wiper assembly 1000.

[0049] The connector 400 of the present application embodiment is described in detail below with reference to the accompanying drawings.

[0050] The connector 400 includes a first connecting portion 11, a second connecting portion 12, and a break-through guide portion 20, with the break-through guide portion 20 located between the first connecting portion 11 and the second connecting portion 12.

[0051] The fracture guide 20 is configured to guide the connector 400 to fracture after the impact force received by the connector 400 reaches a threshold. The fracture guide 20 can be a part of the connector 400 with low material strength or a part of the connector 400 with reduced thickness.

[0052] The first connecting portion 11 is used to connect the first component, and the second connecting portion 12 is used to connect the second component. The first connecting portion 11 mentioned in this application embodiment can be the first mounting base 100 mentioned above, and the second connecting portion 12 mentioned in this application embodiment can be the second mounting base 200 mentioned above. The following description uses the first component as the first mounting base 100 and the second component as the second mounting base 200 as examples.

[0053] The first connecting portion 11 and the second connecting portion 12 can be structures such as connecting holes or connecting rings. In some embodiments, the first connecting portion 11 and the second connecting portion 12 are connecting holes, the first connecting portion 11 is connected to the first mounting base 100 by a threaded component, and the second connecting portion 12 is connected to the second mounting base 200 by a threaded component. Threaded components include, but are not limited to, bolts, pins, etc.

[0054] In this embodiment, a fracture guide 20 is provided between the first connecting part 11 and the second connecting part 12. The fracture guide 20 guides the connecting part 400 to fracture after the impact force on the connecting part 400 reaches a threshold, so that the first connecting part 11 and the second connecting part 12 are separated or the first connecting part 11 is displaced relative to the second connecting part 12. In this way, the first mounting seat 100 connected to the first connecting part 11 and the second mounting seat 200 connected to the second connecting part 12 are separated from each other or relative displacement occurs, so that the first mounting seat 100 sinks due to the inertia of the impact load. As a result, the height of the first mounting seat 100 protruding from the hood is reduced. This sinking design helps to reduce the injury to the head of pedestrians.

[0055] In addition, the broken part is connector 400. During the after-sales process, only connector 400 needs to be replaced to restore the function of wiper assembly 1000. There is no need to replace the entire wiper assembly 1000. This helps to improve the maintainability of wiper assembly 1000 and reduce the after-sales complaint rate.

[0056] In some embodiments, the first connecting portion 11 and the second connecting portion 12 are arranged side by side so that they can be connected to the first mounting base 100 and the second mounting base 200 respectively, thereby reducing the difficulty of connection.

[0057] In some embodiments, the parallel orientation of the first connecting portion 11 and the second connecting portion 12 intersects the extending direction of the fracture guide portion 20. This arrangement facilitates the separation of the first connecting portion 11 and the second connecting portion 12 after the connector 400 fractures, allowing the first mounting base 100 connected to the first connecting portion 11 to sink.

[0058] For example, the first connecting portion 11 and the second connecting portion 12 are arranged side by side along the X direction, and the breakage guide portion 20 extends along the Y direction, with the X direction perpendicular to the Y direction.

[0059] The collapse-break design described above can be understood as a pedestrian protection collapse-break force design. The pedestrian protection collapse-break force design needs to take into account the after-sales complaint rate to prevent the wiper assembly 1000 from collapsing during normal use within its lifespan.

[0060] Therefore, in some embodiments, the connector 400 further includes a body 10 and a third connecting portion 30, with the first connecting portion 11 and the second connecting portion 12 located on the body 10. The third connecting portion 30 is disposed on one side of the body 10 in the thickness direction and is located between the first connecting portion 11 and the second connecting portion 12, and the break-through guide portion 20 is disposed on the third connecting portion 30.

[0061] The third connecting part 30 is used to connect the first mounting base 100 and the second mounting base 200. The design of the third connecting part 30 helps to improve the connection stability between the connector 400 and the first mounting base 100 and the second mounting base 200, thereby improving the structural stability of the wiper assembly 1000 and reducing the after-sales complaint rate.

[0062] It should be noted that in other embodiments, the third connecting part 30 may not be provided. For example, the body 10 may be constructed as a flat plate, and the fracture guide part 20 may be a V-shaped groove provided on one side of the body 10.

[0063] In some embodiments, the third connection portion 30 is located below the body 10. This allows the connector 400 to stably bear the load through the body 10 during use, thereby preventing the wiper assembly 1000 from breaking down during normal use over its lifespan.

[0064] In some embodiments, the first connecting portion 11 is used to connect the first mounting base 100 from a first direction (Z direction in the figure), the second connecting portion 12 is used to connect the second mounting base 200 from the first direction, and the opposite sides of the third connecting portion 30 are used to connect the first mounting base 100 and the second mounting base 200 from a second direction (X direction in the figure), respectively, with the first direction intersecting the second direction. This helps to improve the connection stability between the connector 400 and the first mounting base 100 and the second mounting base 200, and improves the structural stability of the wiper assembly 1000.

[0065] When in use, the first direction is vertical, the second direction is horizontal, and the first direction is perpendicular to the second direction.

[0066] In some embodiments, the third connecting portion 30 has an opening 40 along its axial direction, and the break-through guide portion 20 is located on the side of the opening 40 away from the body 10.

[0067] In this embodiment, the body 10 makes the connector 400 less likely to break when the wiper assembly 1000 is working normally, thus alleviating the after-sales complaint rate. The opening 40 breaks the continuity of the material of the third connecting part 30, so that the connector 400 can break effectively when it is impacted by a pedestrian, which helps to improve the breakage reliability of the connector 400.

[0068] Furthermore, the design of the opening 40 allows the breaking capacity of the connector 400 to be controlled by adjusting the size or number of the openings 40, while keeping the outer contour size of the connector 400 unchanged. This enables the production of connectors 400 with different breaking capacities but the same size, which helps to standardize the production of the connector 400 and the components connected to the connector 400 and reduces production difficulty.

[0069] In some embodiments, the extension direction of the opening 40 is the same as the extension direction of the break-through guide 20, which helps to improve the break-through reliability of the connector 400.

[0070] For example, both the opening 40 and the fracture guide 20 extend along the Y direction, with the fracture guide 20 located at the bottom of the third connector 30. When impacted by a pedestrian, the bottom of the connector 400 strikes an adjacent component, causing the fracture guide 20 to crack, which in turn causes the body 10 to crack, subsequently leading to the fracture of the connector 400.

[0071] Reference Figure 6 In some embodiments, the opening 40 penetrates the body 10 radially to define a weak portion A on the body 10, the weak portion A being located between the first connecting portion 11 and the second connecting portion 12.

[0072] It is understandable that the opening 40 reduces the local thickness of the body 10, thus forming a weak point A, which helps improve the failure reliability of the connector 400. For example... Figure 6 As shown, the weak part A is above the opening 40, and the fracture guide part 20 is below it. When impacted by a pedestrian, the fracture path is from bottom to top, with the fracture guide part 20 cracking and the weak part A cracking in sequence.

[0073] In some embodiments, the opening 40 extends axially through the third connection 30. This helps to improve the breakage reliability of the connector 400.

[0074] Reference Figure 6 In some embodiments, the third connecting portion 30 has a first inclined surface 311 and a second inclined surface 312 facing away from the body 10, the included angle between the first inclined surface 311 and the second inclined surface 312 facing away from the body 10, and the break-through guide portion 20 is located at the junction of the first inclined surface 311 and the second inclined surface 312. For example... Figure 6 As shown, the V-shaped groove defined by the first inclined surface 311 and the second inclined surface 312 is the breakage guide part 20.

[0075] When the connector 400 is impacted by a pedestrian, the first inclined surface 311 and the second inclined surface 312 tend to flatten out. The first inclined surface 311 and the second inclined surface 312 are subjected to tensile force, and the body 10 is subjected to compressive force. Due to the characteristic that the tensile strength of the material is less than its compressive strength, a crushing crack first occurs at the position of the fracture guide part 20 below the connector 400, and micro-cracks are formed at the stress concentration point, which then become the mechanical weak point of the connector 400 and extend from bottom to top. Finally, the crack reaches the top surface of the connector 400, and the entire structure of the connector 400 breaks. Then, the first mounting base 100 connected to the first connecting part 11 sinks down, thereby protecting the pedestrian's head.

[0076] Reference Figure 6In some embodiments, the angle between the first inclined plane 311 and the second inclined plane 312 is α, satisfying 100°≤α≤150°. This setting helps to improve the failure reliability of the connector 400.

[0077] For example, α can be 100°, 110°, 120°, 130°, 140°, 150° and any value in between.

[0078] Of course, in other implementations, the first inclined surface 311 and the second inclined surface 312 may not intersect. For example, a rectangular groove is provided between the first inclined surface 311 and the second inclined surface 312. The rectangular groove is located between the first inclined surface 311 and the second inclined surface 312, and the rectangular groove is the breakage guide 20.

[0079] For example, the first inclined surface 311 and the second inclined surface 312 are smoothly transitioned, and the position of the smooth transition between the first inclined surface 311 and the second inclined surface 312 defines an arc-shaped groove. The arc-shaped groove is located between the first inclined surface 311 and the second inclined surface 312, and this arc-shaped groove is the breakage guide part 20.

[0080] In some embodiments, the distance between the opening 40 and the fracture guide 20 is less than the thickness of the weak portion A, which helps the connector 400 to fracture effectively when it receives an impact.

[0081] Reference Figures 5 to 9 In some embodiments, the third connecting portion 30 is provided with a first engaging portion 313 for engaging the first mounting base 100. In some embodiments, the third connecting portion 30 is provided with a second engaging portion 314 for engaging the second mounting base 200.

[0082] The first snap-fit ​​portion 313 and the second snap-fit ​​portion 314 are located on both sides of the third connecting portion 30 along the second direction X.

[0083] It is understood that the third connecting part 30 is connected to the first mounting base 100 via the first snap-fit ​​part 313, and to the second mounting base 200 via the second snap-fit ​​part 314.

[0084] In some embodiments, the first snap-fit ​​portion 313 is a slot. In some embodiments, the second snap-fit ​​portion 314 is a slot. Setting the first snap-fit ​​portion 313 and the second snap-fit ​​portion 314 as slots helps to reduce the difficulty of assembling the connector 400 with the first mounting base 100 and the second mounting base 200.

[0085] In some embodiments, when the first engaging portion 313 is a slot, the third connecting portion 30 is further provided with a first abutting portion 315, which is located at one end in the extending direction of the slot and is used to abut against the first mounting base 100. This arrangement makes it difficult for the first mounting base 100 to come out of the slot, which helps to improve the structural stability of the wiper assembly 1000.

[0086] In some embodiments, when the second engaging portion 314 is a slot, the third connecting portion 30 is further provided with a second abutting portion 316, which is located at one end in the extending direction of the slot and is used to abut against the second mounting base 200. This arrangement makes it difficult for the second mounting base 200 to come out of the slot, which helps to improve the structural stability of the wiper assembly 1000.

[0087] According to a second aspect of this application, a wiper assembly 1000 is provided, including a connector 400 according to any embodiment of the first aspect. Since the wiper assembly 1000 includes the aforementioned connector 400, the wiper assembly 1000 has all the beneficial effects of the connector 400, which will not be repeated here.

[0088] In some embodiments, the wiper assembly 1000 includes a wiper 300, a first mounting base and a second mounting base. The wiper 300 is disposed on the first mounting base, and a connector 400 is connected at one end to the first mounting base 100 and at the other end to the second mounting base 200.

[0089] According to a third aspect of this application, a vehicle is provided that includes a wiper assembly 1000 according to any embodiment of the second aspect. Since the vehicle includes the aforementioned wiper assembly 1000, the vehicle has all the beneficial effects of the wiper assembly 1000, which will not be repeated here.
