Description

Technical Field

[0001] The utility model relates to the technical field of automobile exterior rearview mirrors, and particularly relates to an electric folding mechanism for an automobile exterior rearview mirror. Background Art

[0002] The exterior rearview mirror is a tool for a driver to directly obtain external information such as the rear, side, and bottom of the vehicle while sitting on the driver's seat. For the convenience of the driver's operation, to prevent the occurrence of traffic safety accidents and ensure personal safety, all countries have stipulated that exterior rearview mirrors must be installed on automobiles, and all exterior rearview mirrors must be able to adjust the direction. Through the exterior rearview mirror, the driving speed, distance, and driving intention of the vehicle behind can be understood, so as to make reasonable driving decisions. When reversing into the garage, the exterior rearview mirror can help the driver judge the distance and position between the vehicle and the surrounding obstacles, and ensure that the vehicle is parked in the parking space safely and accurately. In order to reduce the accidental scratching of the exterior rearview mirror, the exterior rearview mirror will be folded when parking.

[0003] After retrieval, in the prior art, the Chinese patent publication number: CN220314873U, discloses an electric folding rearview mirror. The utility model includes a mounting seat, a mirror body, an electric folding device, and a rotating arm. The electric folding device includes a motor housing and a transmission housing integrally arranged; the electric folding device is inserted into the installation cavity from the open end at the lower end of the installation cavity on the rotating arm. The installation cavity includes a motor cavity and a transmission cavity, and the motor cavity and the transmission cavity are in communication; a tensioning part is fixedly arranged on the inner wall of the motor cavity along the direction in which the motor housing is inserted into the motor cavity; after the electric folding device is inserted into the installation cavity, through the guidance of the tensioning inclined surface and the mating surface, an interference fit is gradually formed to limit the motor housing in the motor cavity, so as to limit the electric folding device as a whole in the installation cavity, and avoid the phenomenon that the electric folding device shakes left and right in the installation cavity due to the existence of an assembly gap, and ensure the use stability of the electric folding device and the folding of the rearview mirror.

[0004] However, this device still has the following defects:

[0005] When the electric folding rearview mirror folds and unfolds, it may touch the fingers or other objects of the user, causing damage to the fingers or other objects, and it may also damage the motor or other internal structures inside the exterior rearview mirror. This device does not solve this problem. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0024] An electric folding mechanism for an automotive exterior rearview mirror, including a mounting shell 1, the mounting shell 1 is provided with an inner cavity, the inner cavity includes a driving groove 2 and a mounting groove 3, and further includes a driving assembly, the driving assembly includes a driving body 4, and transmission structures such as a motor and gears are arranged inside the driving assembly. The driving body 4 is slidably installed in the inner cavity, a driving ring 5 is arranged on one side of the driving body 4, the driving ring 5 is arranged in the driving groove 2, and further includes a connecting assembly, the connecting assembly includes a connecting sleeve 6, the connecting sleeve 6 is slidably matched with a fixing seat 7, a driving part 8 is rotatably installed inside the fixing seat 7, the driving part 8 is slidably matched with the connecting sleeve 6, and the top of the driving part 8 abuts against the bottom of the driving ring 5

[0025] By setting the driving body 4, rotational power can be provided for the driving ring 5, and through structures such as the connecting sleeve 6, the fixing base 7, and the driving member 8, the driving ring 5 is connected to the external mounting position of the external mirror, providing power for the rotation of the external mirror, thereby realizing the rotational folding and rotational unfolding of the external mirror. By setting the mounting shell 1, it is convenient for the operator to fix and install the driving body 4 and other structures.

[0026] A first clamping block 9 is integrally formed at the top of the driving member 8, a first clamping groove 10 is formed at the bottom of the driving ring 5, and the first clamping block 9 and the first clamping groove 10 are clamped with each other. A second clamping block 11 is integrally formed at the bottom of the driving member 8, a second clamping groove 12 is formed inside the fixing base 7, and the second clamping block 11 and the second clamping groove 12 are clamped with each other. A positioning block 13 is fixedly installed at the bottom of the connecting sleeve 6, a positioning groove 14 is formed at the bottom of the fixing base 7, and the positioning block 13 is slidably installed in the positioning groove 14. Limiting grooves 15 are formed on both sides of the connecting sleeve 6, and limiting blocks 16 are fixedly installed inside the driving member 8, and the limiting grooves 15 and the limiting blocks 16 are in sliding fit. A fixing sleeve 17 is threadedly installed at the top of the connecting sleeve 6, a spring 18 is slidably sleeved on the surface of the connecting sleeve 6, the top of the spring 18 abuts against the fixing sleeve 17, and the bottom of the spring 18 is fixedly connected to a fixing groove 19 fixedly installed on one side of the mounting shell 1.

[0027] By setting the first clamping block 9 and the first clamping groove 10 to cooperate with each other, the driving ring 5 can drive the driving member 8 to rotate. When the rearview mirror encounters an obstacle, the first clamping block 9 will push structures such as the driving member 8, the connecting sleeve 6, and the fixing base 7 to move downward, simultaneously compressing the spring 18, and causing the first clamping block 9 to disengage from the second clamping block 11, thereby realizing the normal rotation of the driving body 4 and the driving ring 5, while other structures and the external mirror do not rotate, preventing the rearview mirror from pinching the user or damaging other items, and at the same time preventing the motor and other structures from being damaged. As the external resistance disappears, the compressed spring 18 will push structures such as the driving member 8, the connecting sleeve 6, and the fixing base 7 to move upward, causing the first clamping block 9 to be clamped with the second clamping block 11 again, so that the external mirror can rotate normally after the external obstacle is removed.
