Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile accessories, in particular to an automobile outside rearview mirror. BACKGROUND

[0002] The automobile outside rearview mirror is an automobile accessory for a driver to observe the running state of the rear vehicle and pedestrian during driving, and is a necessary guarantee for safe driving. By adjusting the installation angle of the outside rearview mirror, the driver can observe the visual field in a specific direction, which is convenient for safe driving. Therefore, the importance of the outside rearview mirror is known to everyone. Since the outside rearview mirror is installed on both sides of the automobile, the outside rearview mirror installed on the outside of the automobile often uses an electrically driven folding device to avoid the outside rearview mirror colliding with other vehicles and pedestrians to cause vehicle damage or unnecessary disputes when the automobile is driven in a narrow space or a complex situation with many pedestrians. However, in rainy and snowy weather, water mist or snowflakes often adhere to the surface of the mirror, causing the rearview mirror to be blurred and seriously affecting the driver's vision, which also poses a certain safety hazard to driving. Therefore, some manufacturers improve the structure of the rearview mirror by setting a windshield wiper on the mirror surface to remove the water mist. However, due to the irregular shape of the rearview mirror, the traditional cleaning structure is difficult to completely clean the rearview mirror surface, so the defogging effect is not complete, which affects the visual field of the rearview mirror and also causes different wear of each part of the rearview mirror, resulting in scratches on the mirror, thereby affecting the service life of the rearview mirror. In addition, the existing rearview mirror is connected with the shell by hot melt adhesive. When the rearview mirror is replaced, some residual hot melt adhesive is generated inside the shell. When the new rearview mirror is installed, the residual hot melt adhesive inside the shell needs to be cleaned, which consumes a certain amount of time and thus reduces the efficiency of replacing the rearview mirror.

[0003] Therefore, we propose an automobile outside rearview mirror to solve the above problems. SUMMARY

[0004] In view of the deficiencies of the prior art, the automobile outside mirror is provided to solve the problem that water mist or snow often adheres to the surface of the mirror in rainy and snowy weather, causing the rearview mirror to be unclear, seriously affecting the driver's vision, and causing certain safety hazards for driving, so some manufacturers improve the structure of the rearview mirror by setting a windshield wiper on the mirror surface to remove the water mist, but due to the irregular shape of the rearview mirror, the traditional cleaning structure is difficult to completely clean the rearview mirror surface, thus the defogging effect is not complete, the field of view of the rearview mirror is affected, and different parts of the rearview mirror are also caused to be worn differently, resulting in scratches on the mirror, thereby affecting the service life of the rearview mirror, and the existing rearview mirror is connected with the shell through hot melt adhesive, when the rearview mirror is replaced, a certain amount of hot melt adhesive residue is generated in the shell, and when the new rearview mirror is installed, the hot melt adhesive residue in the shell needs to be cleaned, thus a certain amount of time is consumed, and the efficiency of replacing the rearview mirror is reduced.

DETAILED DESCRIPTION

[0030] The automobile outside mirror provided by the embodiment of the application solves the technical problem that in rainy and snowy weather, water mist or snowflakes often adhere to the surface of the lens, causing the rearview mirror to be unclear, seriously affecting the driver's sight, and also causing certain safety hazards in driving, so some manufacturers improve the structure of the rearview mirror by setting a windshield wiper on the lens to remove the water mist, but due to the irregular shape of the rearview mirror, the traditional cleaning structure is difficult to completely clean the rearview mirror surface, thus the defogging effect is not complete, the field of view of the rearview mirror is affected, meanwhile, different parts of the rearview mirror are also caused to be worn differently, scratches are caused on the lens, thus affecting the service life of the rearview mirror, and the existing rearview mirror is connected with the shell through hot melt adhesive, when the rearview mirror is replaced, some residues of the hot melt adhesive are generated in the shell, when the new rearview mirror is installed, the hot melt adhesive residues in the shell need to be cleaned, thus a certain amount of time is spent, and the efficiency of replacing the rearview mirror is reduced.

[0031] The technical scheme in the embodiment of the application is as follows: the heating coil 520 is arranged, and the heating coil 520 generates heat to generate a certain amount of heat. The heating coil 520 cooperates with the heat spreading plate 510, and the second spring 620 provides elastic force to cooperate with the fixed plate 640. The outer side of the heat spreading plate 510 is in abutment with the back surface of the lens 3, so that the heat generated by the heating coil 520 is conducted to the lens 3. Thus, the phenomenon that the lens 3 is fogged and condensed when the automobile is driven in rainy and snowy weather is prevented. The heat generated by the heating coil 520 is transmitted to various positions inside the lens 3 by the fan 7, so that the temperature inside the lens 3 is rapidly increased, the phenomenon that the lens 3 is easily broken due to long-time low temperature is prevented, and the lens 3 is pressed to slide outside the insertion rod 440 through the fixed block 410 and the sleeve 420. The elastic force of the first spring 480 cooperates with the inclined surface of the limiting block 490. At this moment, the sleeve 420 drives the limiting block 490 to slide to the other side of the sliding block 460 through the first extension rod 470. The elastic force of the second spring 620 extrudes the heat spreading plate 510 and the lens 3, so that the lens 3 slides outside the insertion rod 440 through the fixed block 410 and the sleeve 420. At this moment, the limiting block 490 extrudes the sliding block 460 into the inside of the clamping block 450, and the limiting block 490 is separated from the inside of the insertion rod 440 along the curved surface of the clamping block 450. Thus, the lens 3 is replaced, and the efficiency of replacing the lens 3 is improved. The second circular gear 950 is arranged, the rotating output shaft of the motor 930 drives the second circular gear 950 to rotate through the rotating shaft 940, the second circular gear 950 is engaged with the rack 920 through the teeth, the rack 920 drives the connecting rod 870 to move downward through the connecting sleeve 910, so that the connecting rod 870 drives the second bevel gear 880 to disengage from the teeth of the first bevel gear 840. At this moment, the first bevel gear 840 lacks limiting, so that the lens 3 is pressed to disengage the limiting block 490 to the other side of the sliding block 460. The elastic force of the second spring 620 cooperates with the limiting block 490 to extrude the sliding block 460 into the inside of the clamping block 450. Thus, the limiting block 490 is separated from the inside of the insertion rod 440, so that the lens 3 is replaced.
