Description

Technical Field

[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a windshield wiper heat insulation device, a windshield wiper device and a vehicle. Background Art

[0002] The wiper device is an important accessory installed on the vehicle windshield. Its function is to sweep away the rain, snow and dust on the windshield that obstructs the view. The wiper device plays an important role in driving safety. The wiper device is usually driven by a wiper motor. The left and right wiper blades of the wiper device are pressed against the outer surface of the windshield by their own wiper arms. The wiper device drives the speed reduction mechanism to rotate through the wiper motor, and drives the wiper arms and wiper blades to reciprocate through the drive rod system, thereby scraping the windshield.

[0003] Extended-range models are popular models in the vehicle market. The space in the front engine compartment of extended-range models is usually compact and there are more components inside the front engine compartment. However, due to the high temperature of the engine exhaust inside the front engine compartment, it will cause heat radiation to the surrounding components in the front engine compartment, especially the wiper motor. When the temperature inside the front engine compartment is high, the wiper motor cannot work continuously and reliably. Utility Model Content

[0004] In view of this, the embodiments of the present application provide a wiper heat insulation device, a wiper device and a vehicle to solve the problem that the internal temperature of the front cabin of the existing extended-range vehicle model is high, resulting in the wiper motor being unable to work stably.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a wiper insulation device, comprising: a heat insulation cover assembly, having an insulation cavity inside for accommodating a wiper motor of the wiper assembly, the heat insulation cover assembly being arranged around the wiper motor, the heat insulation cover assembly having at least one connection portion for assembly and connection with a vehicle body, and a heat dissipation hole being provided at the top of the heat insulation cover assembly corresponding to the heat generating position of the wiper motor.

[0007] The wiper insulation device provided in the embodiment of the present application has a heat insulation cover assembly arranged around the outside of the wiper motor. The connection between the heat insulation cover assembly and the vehicle is structurally stable and reliable. The heat insulation cover assembly can form a heat insulation structure on the periphery of the wiper motor, which can effectively isolate the wiper motor from the hotter environment inside the front cabin, thereby reducing the heat radiation effect of the heat source inside the front cabin on the wiper motor. The heat insulation cavity inside the heat insulation cover assembly can form an independent working space. The temperature in the heat insulation cavity is relatively low, so that the wiper motor can continue to work stably. At the same time, because the wiper motor itself also generates heat when working, the heat dissipation holes provided on the heat insulation cover assembly can further transfer the temperature inside the heat insulation cavity to the outside, so that the heat generated by the wiper motor itself when working can be dissipated in time, effectively solving the problem that the temperature inside the front cabin of existing extended-range vehicles is high, resulting in the inability of the wiper motor to work stably.

[0008] In a possible implementation of the present application, a drainage hole is further provided at the bottom of the heat insulation cover assembly.

[0009] Beneficial effect: The drainage hole can quickly drain the accumulated water in the insulation cavity, avoiding long-term accumulation of water in the insulation cavity and affecting the normal operation of the wiper motor.

[0011] Beneficial effect: When the vehicle is driving, the fresh air from the outside can flow through the insulation cavity through the air flow channel. The flow of the air flow can quickly and massively take away the heat in the insulation cavity, further improving the heat dissipation effect.

[0012] In a possible implementation of the present application, the heat insulation cover assembly includes an upper cover and a lower cover, and the heat dissipation hole is located in the upper cover.

[0013] Beneficial effects: The heat shield assembly is a split structure, which is convenient for processing and manufacturing, and is also easier to assemble and disassemble.

[0015] Beneficial effects: The overall connection method is simple and reliable, and is easy to assemble. Since the connecting portion is a structure extending toward the vehicle body, the connection holes arranged in this position can effectively avoid the wiper motor, making the installation process of the first fastening component easier.

[0016] In a possible implementation of the present application, the upper cover and the lower cover are connected by a second fastening component, a first assembly hole for the second fastening component to pass through is provided at the edge of the upper cover, and a second assembly hole is provided at a position of the lower cover corresponding to the first assembly hole.

[0017] Beneficial effects: The connection method is simple and reliable.

[0018] In a possible implementation of the present application, the upper cover is provided with a power socket corresponding to the power supply position of the wiper motor, and / or the upper cover and the lower cover are combined to form a through hole for the driving rod of the wiper assembly to pass through.

[0019] Beneficial effects: The external power supply can be conveniently connected to the wiper motor through the power plug interface, which makes it easier to assemble the wiper motor.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0037] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.

[0038] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0039] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0040] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0041] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0042] In the relevant technology, the continuous working temperature of the commonly used wiper motor should be less than 60 degrees. When the wiper motor works continuously in an environment exceeding 60 degrees, it will stop working. Due to the heat radiation effect of the engine in the front cabin of the extended-range vehicle, the temperature of the wiper motor in the front cabin can usually reach above 85 degrees. Therefore, exposing the wiper motor directly in the space inside the front cabin will greatly reduce the working reliability of the wiper motor.

[0043] Combine the following Figures 1 to 10 , describing an embodiment of the present application.

[0044] According to an embodiment of the present application, on the one hand, a wiper heat insulation device is provided, including a heat insulation cover assembly 1, the heat insulation cover assembly 1 has an insulation cavity 101 inside for accommodating a wiper motor 2 of the wiper assembly, the heat insulation cover assembly 1 is arranged around the wiper motor 2, the heat insulation cover assembly 1 has at least one connection portion 1031 for assembly and connection with the body of a vehicle, and a heat dissipation hole 1021 is provided at the top of the heat insulation cover assembly 1 corresponding to the heat generating position of the wiper motor 2.

[0045] The wiper heat insulation device of the present embodiment is applied, and a heat insulation cover assembly 1 is arranged outside the wiper motor 2. The connection between the heat insulation cover assembly 1 and the vehicle is stable and reliable in structure. The heat insulation cover assembly 1 can form a heat insulation structure on the periphery of the wiper motor 2, which can effectively isolate the wiper motor 2 from the hotter environment inside the front cabin, and reduce the heat radiation effect of the heat source inside the front cabin on the wiper motor 2. The heat insulation cavity 101 inside the heat insulation cover assembly 1 can form an independent working space. The temperature in the heat insulation cavity 101 is relatively low, so that the wiper motor 2 can work continuously and stably. At the same time, because the wiper motor 2 itself also generates heat when working, the heat dissipation holes 1021 provided on the heat insulation cover assembly 1 can further transfer the temperature inside the heat insulation cavity 101 to the outside, so that the heat generated by the wiper motor 2 itself when working can be dissipated in time, effectively solving the problem that the temperature inside the front cabin of existing extended-range vehicles is high, resulting in the inability of the wiper motor to work stably.

[0046] It should be noted that there is no limitation on the specific size of the heat shield assembly 1, and the structure of the heat shield assembly 1 can be designed according to the size and outer contour of the wiper motor 2, as long as it can be enclosed outside the wiper motor 2 to isolate the heat source.

[0047] Specifically, in order to prevent the heat shield assembly 1 from directly transferring its own heat to the wiper motor 2 , a certain gap needs to be provided between the inner wall of the heat shield assembly 1 and the wiper motor 2 .

[0048] Preferably, the gap between the inner wall of the heat shield assembly 1 and the wiper motor 2 is greater than or equal to 5 mm. This arrangement can ensure that there is a gap between the heat shield assembly 1 and the wiper motor 2, and can also absorb errors during assembly and manufacturing.

[0049] In some embodiments of the present application, a drainage hole 1032 is further provided at the bottom of the heat insulation cover assembly 1. Since rainwater can enter the insulation cavity 101 through the heat dissipation holes 1021, the drainage holes 1032 can quickly discharge the accumulated water in the insulation cavity 101, thereby avoiding long-term accumulation of water in the insulation cavity 101 and affecting the normal operation of the wiper motor 2.

[0050] There is no limitation on the location, shape and size of the drainage hole 1032. The drainage hole 1032 is preferably located at the lowest position at the bottom of the heat insulation cover assembly 1, which is more conducive to drainage. The drainage hole 1032 can be circular, rectangular, etc., and the size and shape of the drainage hole 1032 can be flexibly selected according to needs.

[0051] In addition, if Figure 3 and Figure 4As shown, since the bottom of the heat insulation cover assembly 1 of this embodiment is relatively flat, only one drainage hole 1032 is set. If the bottom of the heat insulation cover assembly 1 has a plurality of groove-like structures after correspondingly matching with the wiper motor 2, a drainage hole 1032 can be set at the lowest position of each groove-like structure to ensure the drainage effect.

[0052] In some embodiments of the present application, guide holes are provided on the outer trim panel of the corresponding heat insulation cover assembly 1 of the vehicle, and the guide holes are provided corresponding to the heat dissipation holes 1021. The guide holes, the heat dissipation holes 1021 and the drainage holes 1032 form an air flow channel. When the vehicle is driving, the external fresh air can flow through the heat insulation cavity 101 through the air flow channel. The flow process of the air flow can quickly take away a large amount of heat in the heat insulation cavity 101, thereby further improving the heat dissipation effect.

[0053] Specifically, this type of heat shield assembly 1 can keep the operating temperature of the wiper motor 2 between 40 degrees and 53 degrees, and the wiper motor 2 can continue to work reliably at this operating temperature.

[0054] Among them, it should be noted that the exterior trim panel of the corresponding heat insulation cover assembly 1 of the vehicle refers to: the cover assembly on the top of the heat insulation cover assembly 1, which can be the exterior trim panel of the front cabin or the warm air pressure trim panel of the front cabin. As long as the guide holes are opened to introduce the external airflow into the heat dissipation holes 1021, the opening position of the guide holes can be flexibly selected according to the internal structure of the front cabin, and no strict limitation is made here.

[0055] In some embodiments of the present application, the heat shield assembly 1 includes an upper cover 102 and a lower cover 103, and the heat dissipation holes 1021 are located in the upper cover 102. The heat shield assembly 1 is a split structure, which is easy to process and manufacture, and is also easier to assemble and disassemble.

[0056] Among them, there is no limitation on the separation position of the upper cover 102 and the lower cover 103. The upper cover 102 and the lower cover 103 can be evenly divided upper and lower structures, or the upper cover 102 can be a flat plate structure at the top, and the lower cover 103 can be a groove-shaped structure at the bottom. It can also be that the upper cover 102 is a downward-opening groove-shaped structure at the top, and the lower cover 103 is a flat plate structure at the bottom. It can be flexibly selected according to needs.

[0057] Preferably, if Figure 4 As shown, the upper cover 102 and the lower cover 103 are two groove-shaped structures separated along the middle and lower parts of the wiper motor 2 in the height direction of the wiper motor 2. This type of upper cover 102 and lower cover 103 have high strength and are not prone to failure.

[0058] In some embodiments of the present application, the heat insulation cover assembly 1 is connected to the vehicle body through a first fastening component. The portion of the lower cover 103 corresponding to the vehicle body extends toward the vehicle body and forms a connecting portion 1031. The connecting portion 1031 is provided with a connecting hole 1033 for the first fastening component to pass through. The overall connection method is simple and reliable, and is convenient for assembly operation. Since the connecting portion 1031 is a structure extending toward the vehicle body, the connection hole 1033 is arranged in this position to effectively avoid the wiper motor 2, making the installation process of the first fastening component easier.

[0059] It can be understood that, as an alternative embodiment, the heat shield assembly 1 can also be connected to the vehicle body by welding or other connection methods.

[0060] Preferably, the first fastening component is a connecting bolt, and a first matching hole matching with the connecting bolt is provided at a corresponding position of the vehicle body.

[0061] In addition, it should be noted that there is no limitation on the number of the connection parts 1031 , and it may be one connection part 1031 as shown in the accompanying drawings, or it may be a plurality of connection parts 1031 distributed around the outer wall of the lower cover 103 , and the selection may be made according to the assembly connection requirements.

[0062] In some embodiments of the present application, the upper cover 102 and the lower cover 103 are connected by a second fastening component. A first assembly hole 1022 for the second fastening component to pass through is provided at the edge of the upper cover 102, and a second assembly hole 1034 is provided at a position corresponding to the first assembly hole 1022 of the lower cover 103. The connection method is simple and reliable.

[0063] It can be understood that, as an alternative implementation, the upper cover 102 and the lower cover 103 can also be connected by welding or other connection methods.

[0064] The second fastening component may be a connecting pin, a connecting bolt, a connecting rivet, etc. Preferably, the second fastening component is a connecting bolt.

[0065] Specifically, Figures 1 to 4 As shown, there are four connection positions between the upper cover 102 and the lower cover 103, three of which are formed by extending outward from the edge positions of the upper cover 102 and the lower cover 103 and overlapping, and one of which is formed by the edge of the upper cover 102 extending toward one side of the lower cover 103 and overlapping with the lower cover 103, and the first assembly hole 1022 and the second assembly hole 1034 are correspondingly arranged at the connection position.

[0066] In some embodiments of the present application, the upper cover 102 is provided with a power socket 1023 corresponding to the power supply position of the wiper motor 2, and an external power source can be conveniently connected to the wiper motor 2 through the power socket 1023, which makes it easier to assemble the wiper motor 2.

[0067] There is no limitation on the shape and size of the power plug interface 1023 , and it can be designed according to the shape and size of the external power plug terminal, as long as the external power plug terminal can pass through and connect to the wiper motor 2 .

[0068] In some embodiments of the present application, the upper cover 102 and the lower cover 103 are combined to form a through hole 1024 for the driving rod 3 of the wiper assembly to pass through. This form of upper cover 102 and lower cover 103 can better match the outer contours of the remaining components of the wiper assembly to avoid interference with the driving rod 3.

[0069] In some embodiments of the present application, the upper cover 102 is a metal component and the lower cover 103 is a plastic component. This form of the upper cover 102 has better thermal conductivity and is more convenient for heat dissipation. This form of the lower cover 103 can meet the strength requirements while being lighter.

[0070] Among them, there is no limitation on the specific material of the upper cover 102, which can be steel sheet metal, aluminum alloy sheet metal, etc. The plastic model used for the lower cover 103 can be flexibly selected according to demand, as long as the structure has high strength and is not easily deformed by heat.

[0071] In some embodiments of the present application, a mounting opening 1035 is further provided in the middle of the lower cover 103 , and the transmission structure in the wiper assembly can be connected to the wiper motor 2 through the mounting opening 1035 .
