Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0042] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0044] like Figure 1 , Figure 7 and Figure 8 As shown, in the embodiment, a wind noise prevention structure 100 is provided, which can be applied to the rearview mirror of the car. The wind noise prevention structure 100 can be arranged at one end of the mirror seat 300 in the rearview mirror facing the mirror body structure 200, which can reduce the possibility of airflow entering the mirror seat 300, realize the wind noise reduction function, and provide a defrosting function in a cold environment, so that the rearview mirror can be smoothly unfolded and folded. In some embodiments, a folding structure (not shown) is also arranged between the mirror seat 300 and the mirror body structure 200, and the mirror body structure 200 can be rotated relative to the mirror seat 300 through the folding structure to realize the folding and unfolding of the rearview mirror.

[0045] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the wind noise prevention structure 100 may include a bracket 110, a soft rubber pad 120 and a heating element 130. The bracket 110 may be used as an installation carrier in the wind noise prevention structure 100, and other structural components in the wind noise prevention structure 100 may be attached to the bracket 110 for installation.

[0046] In some embodiments, the soft rubber pad 120 may be disposed on one side of the bracket 110, and the peripheral edge of the bracket 110 may be covered by the soft rubber pad 120. Therefore, when the wind noise prevention structure 100 is applied to a rearview mirror, the soft rubber pad 120 may be used to seal the connection position, thereby reducing the possibility of wind noise caused by airflow entering the mirror seat 300 in the rearview mirror, thereby achieving the effect of reducing wind noise.

[0047] In some embodiments, the heating element 130 may be disposed on a side of the bracket 110 facing the soft rubber pad 120. During use, when the gap between the mirror body structure 200 and the mirror base 300 in the rearview mirror is frozen, the heating element 130 in the wind noise prevention structure 100 may be used to generate heat to increase the temperature at the location of the wind noise prevention structure 100. Accordingly, the temperature at the gap between the mirror body structure 200 and the mirror base 300 may also increase and thaw, thereby facilitating the smooth movement of the folding structure in the rearview mirror, so that the rearview mirror can be smoothly unfolded and folded.

[0048] In the embodiment of the present application, by integrating the heating element 130 in the wind noise prevention structure 100, the connection position of the mirror body structure 200 and the mirror base 300 in the rearview mirror can be thawed, so that the rearview mirror can be folded and unfolded smoothly to avoid affecting the normal use of the user. In addition, in the embodiment of the present application, the heating element 130 is integrated into the wind noise prevention structure 100 at one end of the mirror base 300 facing the mirror body structure 200, which can shorten the distance between the heating element 130 and the gap between the mirror base 300 and the mirror body structure 200, that is, shorten the distance of heat transfer. On the one hand, the heat can be quickly transferred to the gap position between the mirror base 300 and the mirror body structure 200, accelerate the thawing of the gap, and shorten the waiting time of the user. On the other hand, it can also reduce the loss of heat in the transfer process, improve the heat utilization rate, and achieve energy saving effect, so that the heat generated by the heating element 130 is used as much as possible to thaw the gap between the mirror base 300 and the mirror body structure 200, which can further improve the rate of thawing the gap.

[0049] like Figures 1 to 3 , Figure 8 As shown, the bracket 110 may include a bracket body 111. In some embodiments, the bracket body 111 may be an annular structure. Accordingly, a first through hole 1111 connecting two opposite sides of the bracket body 111 may be provided in the bracket body 111. When the wind noise prevention structure 100 is applied to a rearview mirror, the first through hole 1111 may allow a connecting shaft connected to the mirror body structure 200 to pass smoothly.

[0050] like Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the heating element 130 may be a heating wire, that is, the heating element 130 is a linear structure. The heating element 130 may include an integrated heating element body 131 and an electrode connecting sheet 132. Among them, two electrode connecting sheets 132 are provided, and the two electrode connecting sheets 132 are respectively provided at the two ends of the heating element body 131. And the electrode connecting sheet 132 can be arranged vertically with the heating element body 131.

[0051] In other embodiments, the heating element 130 may also be a heating plate or a heating rod.

[0052] In the embodiment, the heating element body 131 can be arranged on the side of the bracket body 111 facing the soft rubber pad 120, and can be arranged around the first through hole 1111. The electrode connecting piece 132 can be inserted into the bracket body 111, and protrude from the side of the bracket body 111 away from the heating element body 131. The end of the electrode connecting piece 132 away from the heating element body 131 can be used to connect the wire so as to electrically connect the power supply structure, control system, etc. in the car. Thus, the operation of the heating element 130 can be controlled by the control system, and the power supply structure can be used to power the heating element 130.

[0053] In some embodiments, a connection hole 1321 is opened at one end of the electrode connecting plate 132 away from the heating element body 131, and the connecting terminal on the wire can be inserted into the connection hole 1321, which can reduce the possibility of separation of the wire and the electrode connecting plate 132, thereby reducing the probability of failure of the wind noise protection structure 100.

[0054] like Figures 2 to 7 As shown, in some embodiments, the bracket 110 further includes a support boss 112 which is an integral structure with the bracket body 111, and the support boss 112 may be protrudingly arranged on the side of the bracket body 111 away from the heating element body 131. In the embodiment, the electrode connecting piece 132 may be sequentially arranged in the bracket body 111 and the support boss 112, and protrude relative to the side of the support boss 112 away from the bracket body 111. It can be understood that the support boss 112 may be arranged around the peripheral side of the electrode connecting piece 132, and the support boss 112 may provide corresponding support for the electrode connecting piece 132, thereby improving the stability of the electrode connecting piece 132 and ensuring that the electrode connecting piece 132 is always perpendicular to the heating element body 131, so that during the assembly process, the electrode connecting piece 132 can be smoothly arranged in the lens holder 300 and connected to the wire, and in addition, the plugging and unplugging bearing capacity of the electrode connecting piece 132 can also be improved.

[0055] In some embodiments, the heating element body 131 can be wound around the first through hole 1111 in a double-wire parallel winding manner. Thus, the two ends of the heating element body 131 can be arranged adjacent to each other, and then the two electrode connecting pieces 132 can be arranged adjacent to each other to facilitate the wiring in the rearview mirror. In addition, it can avoid the need to set up an insulating protection structure between the various parts of the heating element body 131 due to cross-wires, thereby reducing the number of parts of the wind noise protection structure 100, achieving a streamlined structure while reducing costs. At the same time, the layout length of the heating element body 131 can also be extended, the heating efficiency can be improved, the thawing time can be reduced, and the waiting time of the user can be reduced. It can be understood that the two parallel structural sections of the heating element body 131 are arranged at intervals to avoid short circuits.

[0056] In some embodiments, the heating element body 131 may further include at least one S-shaped structural segment 1311, which can further extend the layout length of the heating element body 131, improve the heating efficiency, and shorten the user's waiting time.

[0057] For example, in some embodiments, the heater body 131 may include an S-shaped structural segment 1311 , and the S-shaped structural segment 1311 may be located on a structural segment of the heater body 131 close to the first through hole 1111 .

[0058] In other embodiments, the heating element body 131 may also include two, three, or any other number of S-shaped structural segments 1311 .

[0059] like Figures 2 to 5 As shown, in some embodiments, a side of the support body 111 away from the support boss 112 may be provided with an embedding groove 1112. The heating element body 131 may be embedded in the embedding groove 1112, and the heating element body 131 may fit with the inner wall of the embedding groove 1112. It is understandable that the shape of the embedding groove 1112 may be adapted to the shape of the heating element body 131. Thus, the heating element body 131 may be prevented from moving arbitrarily relative to the support body 111, and a short circuit may be avoided between two parallel structural sections of the heating element body 131 due to contact.

[0060] In some embodiments, the heater 130 and the bracket 110 may be connected by injection molding. Specifically, the heater 130 may be arranged in a mold for injection molding the bracket 110, and then the bracket 110 may be injection molded in the mold to fix the heater 130 and the bracket 110 together.

[0061] In other embodiments, the heating element 130 may also be fixed to the bracket 110 by gluing or clamping.

[0062] like Figure 3 , Figure 4 and Figure 7 As shown, in some embodiments, a buckle 113 may be further configured on one side of the bracket body 111 facing the supporting boss 112 , which can be used to be snap-fitted with the mirror holder 300 .

[0063] Of course, the bracket 110 and the mirror base 300 may be further fixed by means of screw connection or the like to prevent the bracket 110 from being separated from the mirror base 300 at will, thereby preventing the wind noise protection structure 100 from being separated from the mirror base 300 at will.

[0064] like Figure 2As shown, in some embodiments, the bracket 110 may be made of an insulating material, and the temperature resistance may be greater than or equal to 80°C, so as to avoid the bracket 110 from melting and being damaged when the heating element 130 generates heat. For example, in some embodiments, the bracket 110 may be made of one or more combinations of materials such as acrylonitrile-styrene-butadiene copolymer (ABS), acrylonitrile-styrene-acrylic rubber (ASA), nylon + glass fiber, polypropylene (PP) + glass fiber, etc.

[0065] In some embodiments, the heating element 130 may be made of one or more materials such as metal materials, alloy materials or ceramic materials, and may have good heating performance.

[0066] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the wind noise protection structure 100 further includes a waterproof member 140. The waterproof member 140 may also be an annular structure, and accordingly, the waterproof member 140 may be provided with a second through hole 141 connecting two opposite sides of the waterproof member 140.

[0067] In the embodiment, the waterproof member 140 may be disposed on the side of the heating element body 131 facing the soft rubber pad 120. The waterproof member 140 may cover the embedding groove 1112, and the side surface of the waterproof member 140 facing the bracket 110 may be sealed and fitted with the bracket body 111. Thus, the embedding groove 1112 may be sealed, and the heating element body 131 may be waterproofed. In addition, the second through hole 141 on the waterproof member 140 may be relatively connected to the first through hole 1111 on the bracket body 111. And the shape and size of the second through hole 141 may be roughly consistent with the shape and size of the first through hole 1111.

[0068] In some embodiments, the waterproof member 140 can be bonded to the bracket body 111 by a double-sided adhesive tape 150. At the same time, a sealed connection between the waterproof member 140 and the bracket body 111 can also be achieved. Accordingly, a third through hole 151 opposite to and connected to the second through hole 141 can also be formed on the double-sided adhesive tape 150. The shape and size of the third through hole 151 can be roughly consistent with the shape and size of the second through hole 141.

[0069] In other embodiments, the waterproof member 140 may also be bonded to the bracket body 111 by glue.

[0070] In some embodiments, the waterproof member 140 may be made of insulating material, and the heat-resistant temperature of the waterproof member 140 may be greater than or equal to 80°C.

[0071] In some embodiments, the base film in the double-sided adhesive 150 may be made of materials such as polyethylene terephthalate (PET).

[0072] like Figures 2 to 4 As shown, a ring-shaped sinking groove 1113 is further configured on one side of the bracket body 111 facing the soft rubber pad 120. The waterproof member 140 can be accommodated in the sinking groove 1113.

[0073] In addition, at least one first positioning protrusion 1114 is protruded from one side of the bracket body 111 facing the waterproof member 140, and the first positioning protrusion 1114 can be disposed in the sinking groove 1113. Specifically, the first positioning protrusion 1114 can be protruded from the bottom of the sinking groove 1113 in a direction away from the supporting boss 112, and the first positioning protrusion 1114 can be located on a side of the embedding groove 1112 away from the first through hole 1111.

[0074] At least one first positioning groove 142 may be provided on the waterproof member 140. The first positioning groove 142 may be provided at an edge of the waterproof member 140. At least one first positioning protrusion 1114 may be inserted into the at least one first positioning groove 142 in a one-to-one correspondence. Thus, during the assembly process, the waterproof member 140 and the bracket 110 may be positioned to improve assembly accuracy and assembly efficiency.

[0075] In some embodiments, three first positioning protrusions 1114 may be protruded from one side of the bracket body 111 facing the waterproof member 140. Three first positioning grooves 142 may be opened on the waterproof member 140. The three first positioning protrusions 1114 are inserted into the three first positioning grooves 142 in a one-to-one correspondence.

[0076] In other embodiments, one, two, four or any other number of first positioning protrusions 1114 may be protruded from one side of the bracket body 111 facing the waterproof member 140. The waterproof member 140 may be provided with the same number of first positioning grooves 142 as the first positioning protrusions 1114, and the first positioning grooves 142 may correspond to the first positioning protrusions 1114 one by one.

[0077] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments, the first positioning protrusion 1114 is further provided with an assembly groove 1115 connected to the embedding groove 1112, and the opening of the assembly groove 1115 may face the side of the embedding groove 1112. The side of the assembly groove 1115 facing the soft rubber pad 120 may be a closed structure. A fixing portion 1312 is also protrudingly provided on the peripheral side of the structural segment located in the outer ring of the heating element body 131. The fixing portion 1312 is inserted and limited in the assembly groove 1115. Therefore, under the cooperation of the first positioning protrusion 1114 and the fixing portion 1312, a limiting function in the direction perpendicular to the bracket body 111 can be provided for the heating element 130, preventing the heating element 130 from arbitrarily detaching from the bracket 110, that is, further improving the connection stability between the heating element 130 and the bracket 110.

[0078] like Figures 2 to 4 As shown, the soft rubber pad 120 may also be an annular structure, and a fourth through hole 121 may be provided on the soft rubber pad 120 to connect the two opposite sides thereof. The soft rubber pad 120 may be connected to the side of the bracket body 111 away from the support boss 112, and the soft rubber pad 120 may be arranged around the waterproof member 140.

[0079] In some embodiments, at least one second positioning protrusion 122 may be protruded from one side of the soft rubber pad 120 facing the fourth through hole 121. At least one second positioning groove 1116 may be provided on one side of the bracket body 111 away from the supporting boss 112, and the at least one second positioning groove 1116 may be arranged around the sink 1113. In an embodiment, at least one second positioning protrusion 122 may be inserted into at least one second positioning groove 1116 in a one-to-one correspondence.

[0080] In some embodiments, the side of the soft rubber pad 120 facing the fourth through hole 121 may be protruded with one, two, three or any other number of second positioning protrusions 122. The bracket body 111 may be provided with second positioning grooves 1116 having the same number as the second positioning protrusions 122.

[0081] In some embodiments, the soft rubber pad 120 and the bracket 110 can be integrally molded by a two-color injection molding process.

[0082] In some embodiments, the soft rubber pad 120 may be made of a flexible material such as thermoplastic elastomer (TPE) or thermoplastic vulcanizate (TPV), and the hardness range of the soft rubber pad 120 may be set to 30-65 Shore A.

[0083] like Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, when the wind noise prevention structure 100 is applied to the rearview mirror of the car, the heating element 130 can be electrically connected to the control system and power supply structure of the car. In addition, a current detection element for current detection can be set on the circuit where the drive motor is located in the folding structure. The control system receives the operation instruction input by the user and controls the folding structure of the rearview mirror to start, so that when the rearview mirror is folded or unfolded, when the current detection element detects that the current of the circuit where the drive motor is located reaches a preset value, it means that the load of the drive motor increases, indicating that the gap between the mirror body structure 200 and the mirror seat 300 in the rearview mirror is frozen. The control system can control the heating element 130 to start and work for a preset time to thaw the gap between the mirror body structure 200 and the mirror seat 300. Among them, the preset time can be set as needed, for example, it can be any time length from 3min to 10min. After the heating element 130 works for a preset time, the control system can control the heating element 130 to automatically cut off the power, and the control system can drive the drive motor in the folding structure to start, so that the rearview mirror is unfolded or folded.

[0084] In an embodiment, the car can be wirelessly connected to a mobile terminal such as a mobile phone or a smart watch, and the user can input operating instructions through the mobile terminal for remote control.

[0085] like Figure 2 , Figure 7 and Figure 8 As shown, a rearview mirror is also provided in the embodiment, which may include a mirror body structure 200, a mirror seat 300, a folding structure, and a wind noise prevention structure 100 provided in the embodiment. Among them, the mirror body structure 200 can be rotatably connected to the mirror seat 300. The folding structure can be connected between the mirror body structure 200 and the mirror seat 300, and can be used to drive the mirror body structure 200 to rotate relative to the mirror seat 300 to achieve the unfolding and folding of the rearview mirror. The wind noise prevention structure 100 can be installed at one end of the mirror seat 300 facing the mirror body structure 200, and can achieve the function of reducing wind noise. At the same time, when the gap between the mirror seat 300 and the mirror body structure 200 is frozen, it can also be thawed by the heating element 130 in the wind noise prevention structure 100.

[0086] The embodiment further provides a car, which may include the wind noise protection structure 100 provided in the embodiment.
