Description

Technical Field

[0001] The utility model relates to the technical field of water removal devices, in particular to a water removal device and a vehicle. Background Art

[0002] Rearview mirrors are a tool that drivers use to directly obtain external information from behind, to the sides, and below the vehicle while sitting in the cab. Traffic accidents are common in rainy weather, often due to poor visibility. Water easily accumulates in the vehicle's exterior rearview mirrors, blurring the mirrors and reducing rearward visibility. This can easily lead to collisions during lane changes and overtaking, compromising driving safety.

[0003] To address the problem of blurred exterior mirrors in rainy weather, conventional methods typically include attaching rain shields to the mirrors, spraying waterproof film on the mirror surface, electrically heating the mirrors for demisting, installing a vibrator to remove water, or creating air ducts within the mirrors to remove water. However, rain shields only block rain and are unable to remove rainwater that is attached to the mirrors. The waterproofing effectiveness of these films varies, failing to remove small raindrops and lasting only a short time. Furthermore, if the sprayed waterproof film isn't dried promptly, the mirrors are susceptible to dust contamination. Electric heating is slow to take effect and is ineffective against raindrops and columns. Vibrator demisting methods are complex, costly, and prone to mechanical failure. While creating air ducts within the mirrors for demisting can achieve good demisting results, they require modifications to the mirrors themselves, complicating their structure. Furthermore, since these mirrors are factory-installed, their functionality and functionality are limited in versatility. Utility Model Content

[0004] In view of this, the utility model provides a water removal device and a vehicle to solve the problems of poor water removal effect, high cost, complex structure and poor versatility when removing water from the exterior rearview mirror.

[0005] In the first aspect, the utility model provides a water removal device, including an air guide cover, which is used to be detachably connected to the exterior rearview mirror of the vehicle. The air guide cover is provided with an air guide cavity, an air inlet and an air outlet. The air inlet and the air outlet are both connected to the air guide cavity. The air inlet is located upstream of the air guide cover along the forward direction of the vehicle, and the air outlet is located downstream of the air guide cover along the forward direction of the vehicle, and is arranged toward the mirror surface of the exterior rearview mirror.

[0006] Beneficial effects: the air inlet is arranged at the upstream position of the air guide cover along the forward direction, and the air outlet is located at the downstream position and faces the mirror surface of the exterior rearview mirror, so that when the vehicle moves forward, the natural wind brought by the vehicle speed can enter the air guide cavity through the air inlet, and can be blown out from the air outlet at high speed to blow off the water droplets on the exterior rearview mirror; and as long as the vehicle moves forward, the mirror surface of the exterior rearview mirror can be continuously blown, and the water removal effect is good; since only an air guide cover is detachably installed on the rear exterior mirror, it also has the advantages of simple structure, low cost and easy disassembly and assembly, and there is no need to modify the exterior rearview mirror itself, the scope of application is not limited by the factory of the exterior rearview mirror, and it has good versatility.

[0007] In an optional embodiment, a clamping structure is further included, wherein the clamping structure is fixedly connected to the air guide cover, and the air guide cover is detachably clamped to the exterior rearview mirror via the clamping structure.

[0011] In an optional embodiment, one end of the first cover wall close to the air inlet is bonded to the shell of the exterior rearview mirror via an adhesive.

[0012] Beneficial effect: The end of the first cover wall close to the air outlet is detachably connected to the exterior rearview mirror through a clamping structure, and the end close to the air inlet is bonded through an adhesive, which can ensure a relatively stable connection between the air guide cover and the exterior rearview mirror, and prevent the air guide cover from shaking or falling off.
