Description

Technical Field

[0001] This application belongs to the technical field of vehicle accessories, specifically relating to a windshield wiper, a windshield wiper assembly, and a vehicle. Background Technology

[0002] An automobile is a non-rail-mounted vehicle driven by a power unit and having multiple wheels. It is mainly used to carry people and goods and is one of the most important means of transportation in modern society. The windshield wiper is an important component of an automobile. It is installed on the wiper arm and can swing relative to the windshield to wipe away dust and snow on the windshield to ensure the driver's visibility and thus increase driving safety.

[0003] In extremely cold weather, the elasticity of windshield wipers decreases significantly, affecting their ability to clean the windshield. Additionally, frost forms on the windshield in such conditions. Currently, defrosting is primarily achieved by the vehicle's heating system blowing warm air onto the windshield and the wipers working together. Since the heating system mainly utilizes the engine's residual heat, defrosting efficiency is poor when the vehicle is first started.

[0004] To ensure effective windshield wiping and defrosting, heated windshield wipers have emerged. These use integrated heating wires to heat the wiper blades, improving their elasticity in extremely cold weather. While this heating method effectively heats the blades, the limited contact area between the heating wire and the blade results in less than ideal heating performance. To further increase this contact area, windshield wipers with spirally arranged heating wires have appeared. Although this increases the contact area, it also... This is because during the production of wiper blades, the pre-formed heating wire is usually placed in the wiper blade mold, and then the wiper blade raw material is poured into the wiper blade mold so that the raw material is formed into a wiper blade in the wiper blade mold, and the heating wire is located inside the wiper blade. When the wiper blade raw material enters the wiper blade mold, the raw material may impact the heating wire placed inside the wiper blade mold. This causes the heating wire to deform under the impact of the raw material, and may even cause the heating wire to shift to the outer contour of the wiper blade, thus affecting the yield of wiper blades and resulting in higher production costs for wipers. Utility Model Content

[0005] This application provides a windshield wiper to improve the yield of wiper blades and reduce the production cost of the windshield wiper.

[0006] The technical solution adopted in this application is as follows:

[0007] A windshield wiper includes a wiping structure, the wiping structure including a wiper blade, a heating element disposed inside the wiper blade, and a support member disposed on the wiper blade. The support member extends along the length direction of the wiper blade, the heating element is arranged in a continuous curve along the length direction of the wiper blade, and the heating element is connected to the support member so that the support member can support the heating element.

[0008] By adopting the above technical solution, since the wiping structure in this application includes a wiping blade and a heating element disposed inside the wiping blade, the heating element can be used to heat the wiping blade to ensure the elasticity of the wiping blade in extremely cold weather, thereby ensuring the wiping effect of the wiping blade on the windshield; at the same time, the heated wiping blade can also transfer heat to the frost on the windshield, so that the frost on the windshield melts quickly and is wiped away by the wiping blade, thereby improving the defrosting efficiency of the windshield.

[0009] Because the heating element is set in a continuous curve along the length of the wiper blade, the contact area between the heating element and the wiper blade is increased, thereby increasing the heating area of ​​the heating element on the wiper blade and improving the heating effect of the heating element on the wiper blade. This further ensures the elasticity of the wiper blade and further improves the defrosting effect of the wiper blade on the windshield.

[0010] Since the support is located on the wiper blade and the heating element is connected to the support, the support can be used to support the heating element to avoid deformation or displacement of the heating element under the impact of the wiper blade material during the production of the wiper structure. This increases the stability of the heating element and improves the yield of the wiper structure. On the one hand, it reduces the waste of resources, and on the other hand, it reduces the production cost of the wiper.

[0011] Optionally, the wiper further includes a connecting seat connected to the wiper blade, the connecting seat being located at the middle of the wiper blade along its length, and the heating element including a first heating element and a second heating element, the first heating element extending from the connecting seat toward one end of the wiper blade, the second heating element extending from the connecting seat toward the other end of the wiper blade, and at least a portion of the first heating element and the second heating element extending into the connecting seat.

[0012] By adopting the above technical solution, since a connecting seat is provided in the middle of the scraper in the length direction, and at least part of the first heating element and the second heating element extend into the connecting seat, the first heating element and the second heating element can be powered by the connecting seat through an electrical connection with the power supply component on the vehicle, thereby reducing the difficulty of powering the first heating element and the second heating element, and increasing the stability of power supply to the first heating element and the second heating element.

[0013] Optionally, both the first heating element and the second heating element are spirally arranged along the outer peripheral surface of the support member, and both the first heating element and the second heating element are in contact with the outer peripheral surface of the support member.

[0014] By adopting the above technical solution, since both the first heating element and the second heating element are spirally arranged along the outer peripheral surface of the support member, and both the first heating element and the second heating element are in contact with the outer peripheral surface of the support member, the difficulty of forming a continuous curve with the first heating element and the second heating element is reduced, thereby improving the production efficiency of the wiping structure. On the other hand, the support effect of the support member on the first heating element and the second heating element is increased, thereby further increasing the stability of the first heating element and the second heating element, thereby further improving the yield of the wiping structure, and thus further reducing the production cost of the wiper.

[0015] Optionally, the pitch of the first heating element and the pitch of the second heating element are both set to gradually decrease from the connecting seat to the end of the scraper.

[0016] By adopting the above technical solution, since both the first heating element and the second heating element have resistance, the heating power of the end of the first heating element away from the connecting seat is less than the heating power of the end of the first heating element close to the connecting seat, and the heating power of the end of the second heating element away from the connecting seat is less than the heating power of the end of the second heating element close to the connecting seat. In this application, by setting the pitch of the first heating element and the pitch of the second heating element to gradually decrease from the connecting seat to the end of the wiper blade, the distribution density of the first heating element and the second heating element can gradually increase along the direction from the connecting seat to the end of the wiper blade, so as to make the heating effect of the first heating element and the second heating element on any two points on the wiper blade as similar as possible, thereby improving the heating uniformity of the first heating element and the second heating element on the wiper blade, and further improving the elasticity of the wiper blade in extremely cold weather and the defrosting effect of the wiper blade on the windshield.

[0017] Optionally, the wiper also includes a cover, the wiper blade having a connecting section connected to the cover and a wiping section for contacting the windshield, the heating element and the support member being disposed in the connecting section.

[0018] By adopting the above technical solution, in order to ensure the wiping effect of the wiper blade on the windshield and the connection stability between the wiper blade and the shield, the width of the wiping section is usually set to be smaller than the width of the connecting section, while the heating element and the support element are both located in the connecting section. This allows the heating element and the support element to avoid the wiping section from becoming less flexible and easily damaged due to placing the support element and the heating element in the wiping section, thus ensuring the wiping effect and service life of the wiper blade on the windshield. On the other hand, the heating element can be made relatively large to further improve the heating effect of the heating element on the wiper blade, thereby improving the elasticity of the wiper blade in extremely cold weather and ensuring the defrosting effect of the wiper blade on the windshield. Furthermore, the support element can be used to increase the structural strength of the connecting section, thereby improving the connection stability between the connecting section and the shield.

[0019] Optionally, the scraper is equipped with a temperature sensor located outside the protective cover.

[0020] By adopting the above technical solution, since the scraper blade is equipped with a temperature sensor, the temperature of the scraper blade can be detected by the temperature sensor, so that the vehicle can control whether the heating element needs to work and facilitate the control of the heating power of the heating element, thereby achieving precise control of the heating element. Furthermore, since the temperature sensor is located outside the protective cover, the temperature sensor can avoid being covered by the protective cover and thus avoid affecting the accuracy of the temperature sensor's detection of the scraper blade temperature, thereby further realizing precise control of the heating element based on the temperature of the scraper blade.

[0021] Optionally, a thermally conductive adhesive layer is provided on the outside of the heating element, and the thermally conductive adhesive layer contacts the scraper and the support.

[0022] By adopting the above technical solution, since the heating element is provided with a thermally conductive adhesive layer on the outside, on the one hand, the heat generated by the heating element can be quickly transferred to the wiper blade by the thermally conductive adhesive layer, thereby improving the heat transfer efficiency between the heating element and the wiper blade, thus improving the heating effect of the heating element on the wiper blade, improving the elasticity of the wiper blade in extremely cold weather and improving the defrosting effect of the wiper blade on the windshield. On the other hand, the thermally conductive adhesive layer can be used to increase the connection stability between the heating element and the wiper blade, and the heating element can be adhered to the support by the thermally conductive adhesive layer, thereby improving the support effect of the support on the heating element, and further increasing the stability of the heating element.

[0023] Optionally, the scraper is made of polyurethane and graphene fiber, and the exterior of the scraper is coated with fluorosilicone resin.

[0024] By adopting the above technical solutions, polyurethane possesses characteristics such as oil resistance, wear resistance, low-temperature resistance, aging resistance, and high elasticity, while graphene fiber has characteristics such as high flexibility and high thermal conductivity. Therefore, the wiper blade is made of polyurethane and graphene fiber materials, which can improve the service life of the wiper blade and the heating effect of the heating element on the wiper blade. Furthermore, since fluorosilicone resin has characteristics such as solvent resistance, acid and alkali resistance, corrosion resistance, high temperature resistance, and low temperature resistance, a fluorosilicone resin coating is applied to the outside of the wiper blade, which can further improve the service life of the wiper blade and the elasticity of the wiper blade in extremely cold weather, thereby further improving the wiping effect of the wiper blade on the windshield.

[0025] This application also discloses a windshield wiper assembly that reduces the production cost of the wiper assembly while ensuring the windshield wiping and defrosting effects.

[0026] A windshield wiper assembly includes a wiper arm, a drive for oscillating the wiper arm, and a wiper as described above, the wiper being mounted on the wiper arm.

[0027] By adopting the above technical solution, since the wiper assembly in this application uses the aforementioned wiper, the production cost of the wiper assembly is reduced while ensuring the wiping and defrosting effect on the windshield.

[0028] This application discloses a vehicle that reduces production costs while ensuring effective windshield wiping and defrosting.

[0029] A vehicle comprising a windshield wiper as described above or a windshield wiper assembly as described above.

[0030] By adopting the above technical solution, since the vehicle in this application uses the aforementioned windshield wipers or windshield wiper assemblies, the production and manufacturing costs of the vehicle are reduced while ensuring the wiping effect and defrosting efficiency of the windshield wipers.

[0031] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0032] 1. The windshield wiper of this application includes a wiping structure, which includes a wiper blade, a heating element disposed inside the wiper blade, and a support element disposed on the wiper blade. The support element extends along the length direction of the wiper blade, and the heating element is arranged in a continuous curve along the length direction of the wiper blade. The heating element is connected to the support element so that the support element can support the heating element, thereby preventing the heating element from deforming or displacing under the impact of the wiper blade material during the production of the wiping structure. This increases the stability of the heating element and improves the yield of the wiping structure, thereby reducing resource waste and reducing the production cost of the windshield wiper.

[0033] 2. The wiper in this application also includes a connecting seat connected to the wiper blade. The connecting seat is located in the middle of the wiper blade along its length. The heating element includes a first heating element and a second heating element. The first heating element extends from the connecting seat toward one end of the wiper blade, and the second heating element extends from the connecting seat toward the other end of the wiper blade. At least a portion of the first heating element and the second heating element extends into the connecting seat. This allows the connecting seat to be electrically connected to a power supply component on the vehicle to supply power to the first heating element and the second heating element, thereby reducing the difficulty of supplying power to the first heating element and the second heating element and increasing the stability of the power supply to the first heating element and the second heating element.

[0034] 3. In this application, both the first heating element and the second heating element are spirally arranged along the outer peripheral surface of the support member, and both the first heating element and the second heating element are in contact with the outer peripheral surface of the support member. This reduces the difficulty of forming a continuous curve with the first heating element and the second heating element, thereby improving the production efficiency of the wiping structure. On the other hand, it increases the support effect of the support member on the first heating element and the second heating element, thereby further increasing the stability of the first heating element and the second heating element, further improving the yield of the wiping structure, and further reducing the production cost of the wiper.

[0043] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0045] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 application.

[0046] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," 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, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0047] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0048] Reference Figures 1 to 5A windshield wiper is disclosed, which includes a wiping structure 1. The wiping structure 1 includes a wiper blade 11, a heating element 12 disposed inside the wiper blade 11, and a support member 13 disposed on the wiper blade 11. The support member 13 extends along the length direction of the wiper blade 11, and the heating element 12 is arranged in a continuous curve along the length direction of the wiper blade 11. The heating element 12 is connected to the support member 13 so that the support member 13 can support the heating element 12.

[0049] Since the swiping structure 1 in this application includes a swiping blade 11 and a heating element 12 disposed inside the swiping blade 11, the heating element 12 can be used to heat the swiping blade 11 to ensure the elasticity of the swiping blade 11 in extremely cold weather, thereby ensuring the swiping effect of the swiping blade 11 on the windshield; at the same time, the heated swiping blade 11 can also transfer heat to the windshield so that the frost on the windshield melts quickly and is scraped away by the swiping blade 11, thereby improving the defrosting efficiency of the windshield.

[0050] Since the heating element 12 is arranged in a continuous curve along the length of the scraper 11, the contact area between the heating element 12 and the scraper 11 is increased, thereby increasing the heating area of ​​the heating element 12 on the scraper 11 and improving the heating effect of the heating element 12 on the scraper 11. This further ensures the elasticity of the scraper 11 and further improves the defrosting effect of the scraper 11 on the windshield.

[0051] Since the support member 13 is located on the wiper blade 11 and the heating element 12 is connected to the support member 13, the support member 13 can be used to support the heating element 12 to avoid deformation or displacement of the heating element 12 under the impact of the wiper blade material during the production of the wiper structure 1. This increases the stability of the heating element 12 and improves the yield of the wiper structure 1. On the one hand, it reduces the waste of resources, and on the other hand, it reduces the production cost of the wiper.

[0052] This application does not specify the arrangement of the heating element 12; preferably, refer to... Figure 1 and Figure 2 The wiper also includes a connecting seat 2 connected to the wiper blade 11. The connecting seat 2 is located in the middle of the wiper blade 11 along its length. The heating element 12 includes a first heating element 121 and a second heating element 122. The first heating element 121 extends from the connecting seat 2 toward one end of the wiper blade 11, and the second heating element 122 extends from the connecting seat 2 toward the other end of the wiper blade 11. At least a portion of the first heating element 121 and the second heating element 122 extends into the connecting seat 2.

[0053] Understandably, the connector 2 is used to connect to the vehicle's wiper arm so that the wiper arm can drive the wiper to swing relative to the windshield, thereby enabling the wiper to sweep the windshield.

[0054] Since a connecting seat 2 is provided in the middle of the wiper blade 11 along its length, at least a portion of the first heating element 121 and the second heating element 122 extend into the connecting seat 2, and the connecting seat 2 can be connected to the wiper arm of the vehicle. In this way, the wiring harness that supplies power to the heating element 12 can be installed on the wiper arm. On the one hand, the first heating element 121 and the second heating element 122 can be powered by the connecting seat 2 through an electrical connection with the power supply component on the vehicle, thereby reducing the difficulty of powering the first heating element 121 and the second heating element 122. On the other hand, the power supply stability of the first heating element 121 and the second heating element 122 can be increased.

[0055] It should be noted that the middle part of the scraper blade 11 along its length can be either the middle position along the length of the scraper blade 11 or a segment of the middle position along the length of the scraper blade 11.

[0056] This application does not specifically limit the power supply method for the first heating element 121 and the second heating element 122. Preferably, the connector 2 is provided with a plug-in conductive structure, and the portions of the first heating element 121 and the second heating element 122 extending into the connector 2 are electrically connected to the plug-in conductive structure. The vehicle's wiper arm is provided with a mating structure that engages with the plug-in conductive structure. The wiring harness supplying power to the first heating element 121 and the second heating element 122 is connected to the mating structure, so that power is supplied to the first heating element 121 and the second heating element 122 through the wiring harness. In other embodiments, a wireless power supply module can also be provided between the connector 2 and the wiper arm to enable wireless power supply to the first heating element 121 and the second heating element 122.

[0057] This application does not specifically limit the form in which the first heating element 121 and the second heating element 122 form a continuous curve. Preferably, refer to... Figure 5 The first heating element 121 and the second heating element 122 are both spirally arranged along the outer peripheral surface of the support member 13, and the first heating element 121 and the second heating element 122 are both in contact with the outer peripheral surface of the support member 13.

[0058] In other words, the first heating element 121 and the second heating element 122 are formed by spirally arranging the first heating element 121 and the second heating element 122 along the outer peripheral surface of the support member 13 in a continuous curve manner in the length direction of the scraper 11.

[0059] Since the first heating element 121 and the second heating element 122 are both spirally arranged along the outer peripheral surface of the support member 13, and the first heating element 121 and the second heating element 122 are both in contact with the outer peripheral surface of the support member 13, the difficulty of forming a continuous curve of the first heating element 121 and the second heating element 122 is reduced, thereby improving the production efficiency of the wiping structure 1. On the other hand, the support effect of the support member 13 on the first heating element 121 and the second heating element 122 is increased, thereby further increasing the stability of the first heating element 121 and the second heating element 122, thereby further improving the yield of the wiping structure 1, and thus further reducing the production cost of the wiper.

[0060] Furthermore, the pitch of the first heating element 121 and the pitch of the second heating element 122 are both set to gradually decrease from the connecting seat 2 to the end of the scraper 11.

[0061] It is understandable that the above-mentioned "the pitch of the first heating element 121 and the pitch of the second heating element 122 are both gradually reduced from the connecting seat 2 to the end of the scraper 11" means that the pitch of the first heating element 121 is gradually reduced in the direction away from the second heating element 122, and the pitch of the second heating element 122 is gradually reduced in the direction away from the first heating element 121.

[0062] Since both the first heating element 121 and the second heating element 122 have resistance, the heating power of the end of the first heating element 121 away from the connecting seat 2 is less than the heating power of the end of the first heating element 121 close to the connecting seat 2, and the heating power of the end of the second heating element 122 away from the connecting seat 2 is less than the heating power of the end of the second heating element 122 close to the connecting seat 2. In this application, by setting the pitch of the first heating element 121 and the pitch of the second heating element 122 to gradually decrease from the connecting seat 2 to the end of the scraper 11, the distribution density of the first heating element 121 and the second heating element 122 can gradually increase along the direction from the connecting seat 2 to the end of the scraper 11, so as to make the heating effect of the first heating element 121 and the second heating element 122 on any two points on the scraper 11 as much as possible, thereby improving the heating uniformity of the scraper 11 by the first heating element 121 and the second heating element 122, and further improving the elasticity of the scraper 11 in extremely cold weather and improving the defrosting effect of the scraper 11 on the windshield.

[0063] In this embodiment, preferably, the support member 13 is disposed inside the scraper 11 so that the entire first heating element 121 and the second heating element 122 can be located inside the scraper 11, thereby improving the heating efficiency of the first heating element 121 and the second heating element 122 on the scraper 11.

[0064] In this embodiment, the structure of the support member 13 is not specifically limited. Preferably, it refers to... Figure 3 and Figure 4 The support member 13 is a cylindrical structure with a circular cross-section to increase the contact area between the first heating element 121 and the second heating element 122 and the support member 13, thereby increasing the supporting effect of the support member 13 on the first heating element 121 and the second heating element 122. In other embodiments, the support member 13 can also be a structure with a square or other shapes.

[0065] In other embodiments, the first heating element 121 and the second heating element 122 may both be in the form of other non-linear shapes such as wavy, serrated, or zebraic. Of course, in these embodiments, the support member 13 is provided with a receiving groove, and at least a portion of the first heating element 121 and the second heating element 122 extends into the receiving groove so that the support member 13 can support the first heating element 121 and the second heating element 122. Furthermore, in these embodiments, a portion of the support member 13 may be located inside the scraper 11, and the remaining portion of the support member 13 may be located outside the scraper 11 and together with the scraper 11 form the outer contour of the scraping structure 1, as long as it can be ensured that the first heating element 121 and the second heating element 122 are completely hidden in the scraping structure 1. In addition, in these embodiments, the distribution density of the first heating element 121 and the second heating element 122 gradually increases along the direction of mutual separation.

[0066] In other embodiments, only one heating element 12 is provided, and the heating element 12 extends from one end of the scraper 11 to the other end of the heating element 12.

[0067] This application does not specify the exact location of the heating element 12 and the support element 13. Preferably, refer to... Figure 3 and Figure 4 The windshield wiper also includes a cover 3, and the wiper blade 11 has a connecting section 111 connected to the cover 3 and a wiping section 112 for contacting the windshield. The heating element 12 and the support member 13 are both located in the connecting section 111.

[0068] It is understandable that the width W1 of the connecting section 111 is greater than the width W2 of the wiping section 112. After the wiper is installed on the vehicle, the wiping section 112 contacts the windshield, and when the wiper swings under the action of the wiper arm, the wiping section 112 rubs against the windshield to achieve wiping of the windshield.

[0069] To ensure the effective wiping of the windshield by the wiper blade 11 and the stability of the connection between the wiper blade 11 and the shield 3, the width of the wiping section 112 is typically set to be smaller than the width of the connecting section 111. The heating element 12 and the support element 13 are both located in the connecting section 111, allowing them to avoid contact with the wiping section 112. This avoids the wiping section 112 becoming less flexible and more prone to damage due to its location, thus ensuring the effective wiping of the windshield by the wiper blade 11 and its service life. Furthermore, the heating element 12 can be made relatively large to further enhance its heating effect on the wiper blade 11, thereby improving the elasticity of the wiper blade 11 in extremely cold weather and ensuring its defrosting effect on the windshield. Additionally, the support element 13 increases the structural strength of the connecting section 111, improving the connection stability between the connecting section 111 and the shield 3.

[0070] The better one is to refer to Figure 3 and Figure 4 The support member 13 and the heating member 12 are both located in the middle of the width direction of the connecting section 111, which improves the heating uniformity of the scraper 11 by the heating member 12 and makes the weight distribution of the scraping structure 1 more uniform.

[0071] The better one is to refer to Figure 1 The protective cover 3 is provided in two sections. The two sections of the protective cover 3 are located on both sides of the connecting seat 2 and are connected to the connecting seat 2, so that the protective cover 3 and the connecting seat 2 are connected as a whole to increase the stability of the scraper 11.

[0072] In other embodiments, the heating element 12 and the support element 13 may also be disposed inside the scraping section 112, or a portion of the heating element 12 and the support element 13 may be located in the scraping section 112, and the remaining portion of the heating element 12 and the support element 13 may be located in the connecting section 111; even, for other non-linear designs such as wavy, serrated, or zebraic heating elements 12, the heating element 12 may be disposed in the scraping section 112, and the support element 13 may be disposed in the connecting section 111.

[0073] In a preferred embodiment, the scraper 11 is provided with a temperature sensor, which is located outside the protective cover 3.

[0074] Understandably, the temperature sensor is used to detect the temperature of the scraper 11.

[0075] Since the scraper 11 is equipped with a temperature sensor, the temperature of the scraper 11 can be detected by the temperature sensor, so as to control whether the vehicle heating element 12 needs to work and to control the heating power of the heating element 12, so as to achieve precise control of the heating element 12.

[0076] Furthermore, since the temperature sensor is located outside the protective cover 3, the temperature sensor can avoid being covered by the protective cover 3, thus preventing the protective cover 3 from affecting the accuracy of the temperature sensor's detection of the scraper 11 temperature, so as to further realize the precise control of the heating element 12 based on the temperature of the scraper 11.

[0077] Preferably, the temperature sensor is electrically connected to the vehicle's PID controller so that the temperature sensor can transmit the temperature signal of the scraper 11 to the vehicle's PID controller, thereby enabling the vehicle's PID controller to accurately control the heating element 12 based on the temperature signal measured by the temperature sensor.

[0078] This application does not impose specific limitations on the placement of the temperature sensor. Preferably, the temperature sensor is located in the middle of the length of the scraper 11, thereby facilitating power supply to the temperature sensor. Of course, in other embodiments, the temperature sensor can be placed at any position along the length of the scraper 11, and a temperature sensor with a built-in battery can be used.

[0079] In a preferred embodiment, a thermally conductive adhesive layer is provided on the outside of the heating element 12, and the thermally conductive adhesive layer contacts the scraper 11 and the support member 13.

[0080] Understandably, the thermally conductive adhesive layer completely encapsulates the heating element 12 in the circumferential direction.

[0081] Because the heating element 12 has a thermally conductive adhesive layer on its exterior, it can quickly transfer the heat generated by the heating element 12 to the scraper 11, thereby improving the heat transfer efficiency between the heating element 12 and the scraper 11. This improves the heating effect of the heating element 12 on the scraper 11, enhances the elasticity of the scraper 11 in extremely cold weather, and improves the defrosting effect of the scraper 11 on the windshield. On the other hand, the thermally conductive adhesive layer can increase the connection stability between the heating element 12 and the scraper 11. The heating element 12 is adhered to the support member 13 by the thermally conductive adhesive layer, thereby improving the support effect of the support member 13 on the heating element 12 and further increasing the stability of the heating element 12.

[0082] This application does not specifically limit the formation method of the thermally conductive adhesive layer. Preferably, the thermally conductive adhesive layer is formed by coating the exterior of the heating element 12 with nano-silver paste to improve the thermal conductivity between the heating element 12 and the scraper 11 and further increase the connection stability between the heating element 12 and the scraper 11. In other embodiments, the thermally conductive adhesive layer may also be formed by other structures that can perform both bonding and thermal conduction, such as polymer-based thermally conductive adhesive coated on the exterior of the heating element 12.

[0083] Of course, in other embodiments, a thermally conductive adhesive layer can be provided at the position where the heating element 12 contacts the scraper 11, and a heat insulation layer can be provided at the position where the heating element 12 contacts the support 13, so as to thermally insulate the heating element 12 from the support 13, thereby allowing all the heat generated by the heating element 12 to be transferred to the scraper 11, so as to further improve the heating efficiency and heating effect of the heating element 12 on the scraper 11.

[0084] This application does not specifically limit the manufacturing material of the scraper 11. Preferably, the scraper 11 is made of polyurethane and graphene fiber, and the exterior of the scraper 11 is coated with fluorosilicone resin.

[0085] Because polyurethane has the characteristics of oil resistance, wear resistance, low temperature resistance, aging resistance, and high elasticity, and graphene fiber has the characteristics of high flexibility and high thermal conductivity, the scraper blade 11 is made of polyurethane and graphene fiber materials, which can improve the service life of the scraper blade 11 and improve the heating effect of the heating element 12 on the scraper blade 11. Furthermore, because fluorosilicone resin has the characteristics of solvent resistance, acid and alkali resistance, corrosion resistance, high temperature resistance, and low temperature resistance, a fluorosilicone resin coating is applied to the outside of the scraper blade 11, which can further improve the service life of the scraper blade 11 and improve the elasticity of the scraper blade 11 in extremely cold weather, thereby further improving the scraping effect of the scraper blade 11 on the windshield.

[0086] Preferably, the graphene fiber accounts for 15% and the polyurethane accounts for 85%, in order to further improve the low-temperature elasticity and thermal conductivity of the scraper 11.

[0087] Furthermore, the thickness H of the fluorosilicone resin coating satisfies: 40μm≤H≤60μm.

[0088] If the thickness of the fluorosilicone resin coating is set to less than 40 μm, the protective effect of the fluorosilicone resin coating on the scraping structure 1 will be poor, and the manufacturing difficulty of the scraping structure 1 will be increased. If the thickness of the fluorosilicone resin coating is set to greater than 60 μm, the manufacturing cost of the scraping structure 1 will increase. Setting the thickness of the fluorosilicone resin coating to greater than or equal to 40 μm and less than or equal to 60 μm can ensure the protective effect of the fluorosilicone resin coating on the scraping structure 1 while reducing the manufacturing difficulty and cost.

[0089] Preferably, the thickness H of the fluorosilicone resin coating is 50 μm, so as to further ensure the protective effect of the fluorosilicone resin coating on the scraping structure 1 while reducing the manufacturing difficulty and cost of the scraping structure 1.

[0090] In other embodiments, the scraper 11 may also be made of other flexible and elastic materials such as rubber.

[0091] This application does not specifically limit the structure of the heating element 12; preferably, refer to... Figure 5 The heating element 12 is a heating wire, and the diameter D of the heating wire satisfies: D≤0.5mm.

[0092] Since the heating element 12 is a heating wire, the manufacturing cost of the wiping structure 1 is reduced on the one hand, and the difficulty of setting the heating element 12 as a continuous curve is reduced on the other hand. At the same time, the support effect of the support element 13 on the heating element 12 is increased, thereby further reducing the manufacturing cost of the wiping structure 1 and improving the yield of the wiping structure 1. Furthermore, since the diameter of the heating wire is less than or equal to 0.5 mm, the heating effect and heating efficiency of the heating wire on the wiper blade 11 are guaranteed on the one hand, the cost of the heating wire is reduced on the other hand, and the situation where the elastic deformation effect of the wiper blade 11 is affected by the large diameter of the heating wire is avoided, so as to ensure the wiping effect of the wiper blade 11 on the windshield.

[0093] In other embodiments, the heating element 12 may also be a heating film to further increase the heating area of ​​the heating element 12 on the scraper 11, thereby further ensuring the elasticity of the scraper 11 in extremely cold weather and the defrosting effect on the windshield.

[0094] This application does not specifically limit the material used to manufacture the support member 13. Preferably, the support member 13 is made of plastic material to reduce the manufacturing cost of the support member 13 and also to reduce the weight of the wiping structure 1, thereby facilitating the lightweight design of the windshield wiper. In other embodiments, the support member 13 may also be made of metal material, such as iron or aluminum.

[0095] This application also discloses a windshield wiper assembly, which includes a wiper arm, a drive for driving the wiper arm to swing, and a wiper as described above, the wiper being mounted on the wiper arm.

[0096] Since the wiper assembly in this application uses the aforementioned wiper, the production cost of the wiper assembly is reduced while ensuring the wiping and defrosting effect on the windshield.

[0097] This application does not specifically limit the structure of the drive component. Preferably, the drive component is a motor, which drives the wiper arm to swing, thereby reducing the production cost of the wiper assembly. In other embodiments, the drive component can also be other structures capable of driving the wiper arm to swing, such as a combination of a cylinder and a connecting rod.

[0098] This application also discloses a vehicle that includes the windshield wipers or the windshield wiper assembly described above.

[0099] Understandably, the wipers are mounted on the wiper arms so that they can rub against the windshield under the action of the wiper arms; the vehicle has a PID controller, and the temperature sensor is electrically connected to the PID controller so that the PID controller can accurately control the heating element.

[0100] Because the vehicle in this application uses the aforementioned windshield wipers, the production and manufacturing costs of the vehicle are reduced while ensuring the wiping effect and defrosting efficiency of the windshield wipers.
