[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] As the available space in the front engine compartment of existing cars becomes less and less, the wiper motor of the wiper system of some models will be directly installed in a closed manner inside the lower part of the front engine compartment trim. The wiper motor is arranged close to the engine. As the engine, which serves as a heat radiation source, continues to work, the ambient temperature inside the front engine compartment is usually high. When the wiper motor works at high temperature for a long time, some internal parts are easily affected, which in turn affects the service life of the wiper motor. Utility Model Content

[0016] In a possible implementation of the present application, a drain port is further provided at the bottom of the heat insulation cover assembly.
[0017] Beneficial effect: Since rainwater from the outside can enter the heat insulation cavity through the heat dissipation port, the drain port can quickly discharge the accumulated water in the heat insulation cavity, thereby preventing long-term accumulation of water in the heat insulation cavity and affecting the normal operation of the wiper motor.
[0018] In a possible implementation of the present application, the wiper insulation device also includes a drain pipe, which is connected to the drain port, and the drain pipe is used to drain the accumulated water in the insulation cavity out of the front cabin of the vehicle.

[0029] 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.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0035] In the related technology, due to the heat radiation of the engine in the front cabin, the temperature at the location of the wiper motor in the front cabin can usually reach above 85 degrees. Since the wiper motor itself will generate heat when working, the wiper motor that continues to work in this environment will further accelerate itself to enter the thermal protection mode, thereby making the wiper motor unable to continue to work stably and reliably.
[0036] Combine the following Figures 1 to 3 , describing an embodiment of the present application.
[0037] According to an embodiment of the present application, on the one hand, a wiper insulation device is provided, comprising: a heat insulation cover assembly 1, the heat insulation cover assembly 1 has a heat 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, and is assembled and connected to a swing shaft 3 of a wiper arm of the wiper assembly, and a heat dissipation port 1021 is arranged on the top of the heat insulation cover assembly 1, and the heat dissipation port 1021 is arranged corresponding to the air vent of the exterior cover of the front cabin of the vehicle.
[0038] By applying the wiper heat insulation device of the present embodiment, a heat insulation cover assembly 1 is arranged around the outside of the wiper motor 2. The heat insulation cover assembly 1 can form a heat insulation structure on the periphery of the wiper motor 2, which can reduce the heat radiation effect of the internal heat source of the front cabin on the wiper motor 2. At the same time, the wiper motor 2 can also directly dissipate its own heat to the outside through the heat dissipation port 1021 corresponding to the air vent, thereby further reducing the temperature inside the heat insulation cavity 101. In addition, since the heat insulation cover assembly 1 is assembled and connected to the swing shaft 3, the heat insulation cover assembly 1 can also be directly disassembled and assembled together with the wiper assembly. The heat damage problem of the wiper motor 2 can be avoided in a simple and reliable way, which effectively solves the problem that the layout of the existing wiper device easily causes damage to the wiper motor.
[0039] 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.
[0040] 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 .
[0041] In some embodiments of the present application, the heat shield assembly 1 includes an upper cover 102 and a lower cover 103, the heat dissipation port 1021 is located on the upper cover 102, the upper cover 102 is assembled and connected to the swing shaft 3, and the heat shield assembly 1 is a split structure, which is convenient for processing and manufacturing, and is also easier to assemble and disassemble.
[0042] In some embodiments of the present application, the heat insulation cover assembly 1 further includes a seal 104, and the upper cover 102 is sealed with the lower cover 103 through the seal 104. The seal 104 can effectively form a seal at the matching position of the upper cover 102 and the lower cover 103 to ensure the heat insulation effect of the heat insulation cover assembly 1 and prevent heat from entering the insulation cavity 101 through the joint between the upper cover 102 and the lower cover 103.
[0043] The specific type of the seal 104 is not limited. The seal 104 may be an independent sealing ring, or a structure in the form of a sealant applied at the joint between the upper cover 102 and the lower cover 103 after the upper cover 102 and the lower cover 103 are assembled.
[0044] Preferably, the sealing member 104 is an independent sealing ring, wherein the matching form of the sealing ring with the upper cover 102 and the lower cover 103 is not limited, and the sealing ring may be provided with grooves at the edge positions corresponding to the upper cover 102 and the lower cover 103, and the upper cover 102 and the lower cover 103 may respectively match with the corresponding grooves, or the upper cover 102 and the lower cover 103 may be provided with grooves at the positions corresponding to the sealing ring, and the two sides of the sealing ring may respectively match with the corresponding grooves;
[0045] It should be noted that the above two matching forms can both ensure the stability and reliability of the assembly of the sealing member 104 , and the sealing member 104 of this form is not easy to fall out from between the upper cover 102 and the lower cover 103 .
[0046] In some embodiments of the present application, fixed ends 1022 are respectively formed at both ends of the upper cover 102 in the extension direction, and an assembly hole 1023 is provided on the fixed end 1022 for the swing shaft 3 to pass through. The two ends of the upper cover 102 are respectively assembled and connected with the corresponding swing shaft 3. The connection form is stable and reliable, and the situation of easy rotation when assembled and connected with a single swing shaft 3 can be avoided.
[0047] Specifically, Figure 1 As shown, when the two assembly holes 1023 of the upper cover 102 are respectively sleeved onto the corresponding swing shafts 3, the two swing shafts 3 can directly position the upper cover 102, and the subsequent lower cover 103 can be directly installed. The positioning process is simple and quick, making the assembly process of the upper cover 102 and the lower cover 103 more accurate.
[0048] In some embodiments of the present application, the portion of the lower side of the upper cover 102 between the two fixed ends 1022 forms an assembly position, and the lower cover 103 is assembled and connected to the assembly position through the seal 104. The assembly connection method is simple and reliable, and is convenient for assembly operation.
[0049] Specifically, Figure 1 and Figure 2 As shown, a matching rod is further provided between the wiper motor 2 and the swing shafts 3 on both sides, and a matching groove is provided on the upper cover 102 and the lower cover 103 corresponding to the position of each matching rod. When the lower cover 103 surrounds the wiper motor 2 from bottom to top and is assembled with the upper cover 102, the upper cover 102 and the lower cover 103 match with the matching rod through the matching grooves at corresponding positions. Since the extension direction of the matching rod is perpendicular to the axial direction of the swing shaft 3, the swing shaft 3 can limit the movement tendency of the upper cover 102 and the lower cover 103 along its own radial direction, and the matching rod can limit the movement tendency of the upper cover 102 and the lower cover 103 along its own radial direction. At this time, the upper cover 102 and the lower cover 103 are reliably fixed to the preset position, and the fixing method is simple and reliable, and does not need to be connected to the vehicle body, and does not require additional components to be connected to the wiper assembly.
[0050] Furthermore, when the upper cover 102 and the lower cover 103 are assembled in the above manner, the upper cover 102 only needs to have the assembly hole 1023 sleeved with the corresponding swing shaft 3, without the need to use other components for connection.
[0051] In some embodiments of the present application, a drain port 1031 is further provided at the bottom of the heat insulation cover assembly 1. Since rainwater from the outside can enter the heat insulation cavity 101 through the heat dissipation port 1021, the drain port 1031 can quickly discharge the accumulated water in the heat insulation cavity 101, thereby avoiding long-term accumulation of water in the heat insulation cavity 101 and affecting the normal operation of the wiper motor 2.
[0052] Among them, there is no limitation on the setting position and shape and size of the drain outlet 1031. The setting position of the drain outlet 1031 is preferably set at the lowest position of the bottom of the heat insulation cover assembly 1, which is more conducive to drainage; the drain outlet 1031 can be circular, rectangular, etc., and the size and shape of the drain outlet 1031 can be flexibly selected according to needs.
[0053] In some embodiments of the present application, the wiper insulation device also includes a drain pipe 105, which is connected to the drain port 1031. The drain pipe 105 is used to discharge the accumulated water in the insulation cavity 101 out of the front cabin of the vehicle. The drain pipe 105 can transport the accumulated water to a preset position and then discharge it, thereby preventing the accumulated water from contacting the components inside the front cabin and causing corrosion, thereby improving the reliability of drainage.
[0054] Specifically, in order to improve the reliability of the drain pipe 105 when facing vibration, the drain pipe 105 is preferably a flexible pipe.
[0055] In some embodiments of the present application, the lower cover 103 corresponds to the lower contour of the wiper motor 2 and forms a plurality of recessed positions 1032, each recessed position 1032 is provided with a drain outlet 1031, and each drain outlet 1031 is connected to a corresponding drain pipe 105. This arrangement of the drain outlets 1031 can ensure that all accumulated water in the lower cover 103 is discharged, thereby avoiding incomplete drainage.
[0056] In other embodiments, if the bottom of the heat insulation cover assembly 1 is relatively flat, only one drain port 1031 may be provided.
[0057] In this embodiment, the upper cover 102 and the lower cover 103 may be connected by a fastening component or by a clamping member, wherein the fastening component includes but is not limited to connecting bolts, connecting pins, connecting rivets, and the like.
[0058] According to an embodiment of the present application, on the other hand, a wiper device is provided, which includes: a wiper assembly and the above-mentioned wiper heat insulation device, the wiper assembly includes a wiper motor 2, a swing shaft 3 and a wiper arm, the wiper motor 2 is transmitted and cooperated with the wiper arm through the swing shaft 3, the wiper motor 2 is suitable for driving the swing shaft 3 to rotate so that the wiper arm swings; the wiper heat insulation device is surrounded by the outside of the wiper motor 2 and is assembled and connected with the swing shaft 3.
[0059] According to an embodiment of the present application, in another aspect, a vehicle is provided, which includes: the above-mentioned wiper heat insulation device, or the above-mentioned wiper device.
[0060] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.
