Description

Technical Field

[0001] The utility model relates to the technical field of rearview mirror folding, in particular to a driving component of a rearview mirror folding mechanism. Background Art

[0002] The rearview mirror folding function means that the rearview mirrors on both sides of the car can be folded and retracted when necessary, which can be divided into manual and electric types.

[0003] Accidents are unavoidable when vehicles are driving. As the widest component installed on the vehicle, the rearview mirror is most susceptible to impact when it causes friction. In order to avoid scratches to the greatest extent, the rearview mirror needs to have a folding function. The rearview mirror with a folding function can be retracted when passing through narrow sections, which improves the vehicle's passability. When the driver leaves the car, the rearview mirror can also be folded up, which not only protects the mirror surface, but also reduces the parking space, effectively avoiding scratches.

[0004] The existing rearview mirror folding mechanism cannot be selected between electric and manual according to the needs, which limits the use of the rearview mirror and is not conducive to the use needs. In view of this, we propose a driving component of the rearview mirror folding mechanism. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The driving component of the rearview mirror folding mechanism can select the folding mode of the rearview mirror according to the needs. When the power is on, the micro motor can be turned on by controlling the switch, so that the rack seat moves along the center line direction of the micro motor output shaft.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figure 1-5 The utility model provides a technical solution: a driving component of a rearview mirror folding mechanism, mainly aimed at improving the problem that the electric and manual folding mechanisms of the existing rearview mirrors cannot be selected according to the needs, resulting in the use of the rearview mirrors being limited and not conducive to the use needs. The specific scheme is as follows: it includes a mirror carrier 1, a glass mirror 2 and an electric element 3, the electric element 3 is fixedly installed on the car body, and the mirror carrier 1 and the glass mirror 2 are fixedly installed.

[0026] See also Figure 1 and Figure 2 , wherein a support rod 11 is fixedly installed on the right side of the mirror carrier 1, a reinforcement member 12 is arranged above the support rod 11, the reinforcement member 12 is internally connected to the support rod 11, and the reinforcement member 12 and the support rod 11 are fixedly installed. The material of the mirror carrier 1 is ABS, which is a material with high strength, good toughness, and easy processing and molding, and the material has outstanding heat resistance and weather resistance.

[0027] See also Figure 1 and Figure 3 A rotating shaft 13 is vertically mounted on the side of the support rod 11 away from the mirror carrier 1, and the rotating shaft 13 and the mirror carrier 1 are integrally mounted. A driving wheel 14 is slidably connected to the upper end of the rotating shaft 13. After the driving wheel 14 rotates, it can drive the rotating shaft 13 and the entire mirror carrier 1 to rotate a certain angle, so that the rearview mirror is easy to fold.

[0028] It is worth mentioning that an easily foldable silicone member is provided between the mirror carrier 1 and the car body, and the silicone member can prevent rainwater, dust, etc. from entering the interior of the car body, thereby affecting the connection and causing influence on the driven electrical components.

[0029] Furthermore, the reinforcing member 12 is internally movably connected with a limit rod 15, a convex plate 19 is arranged above the limit rod 15, a clamping plate 18 is movably contacted above the convex plate 19, the clamping plate 18 is fixedly installed with the reinforcing member 12, the limit rod 15 and the driving wheel 14 are connected through a support plate 17, and the support plate 17 and the driving wheel 14 are connected through a bearing. Through the setting of the support plate 17, the limit rod 15 and the driving wheel 14 can move at the same time, and by operating the limit rod 15, the limit rod 15 can drive the driving wheel 14 to move from bottom to top or from top to bottom, and the electric and manual switching can be realized, which is more convenient for the use of the rearview mirror. By setting the clamping plate 18 and the protruding plate 19, the limit rod 15 can be restricted as needed. When the protruding plate 19 is set directly below the clamping plate 18, the upward movement of the limit rod 15 can be restricted by the clamping plate 18; and when the upper and lower positions of the protruding plate 19 and the clamping plate 18 are staggered, at this time, after the limit rod 15 is freed from the restriction of the clamping plate 18, the limit rod 15 can be operated.

[0030] Furthermore, the support plate 17 is arranged inside the support rod 11, and the center lines of the support plate 17, the limiting rod 15 and the rotating shaft 13 are perpendicular to each other. The driving wheel 14 and the rotating shaft 13 are movably connected, and the driving wheel 14 is arranged outside the support rod 11. A reset spring 16 is movably sleeved on the limiting rod 15; the center lines of the rotating shaft 13 and the limiting rod 15 are parallel to each other, and the limiting rod 15 is arranged above the rotating shaft 13. Among them, the reset spring 16 is connected to the limiting rod 15. Through the setting of the reset spring 16, the limiting rod 15 can move upward in the initial state. In this state, the support plate 17 and the driving wheel 14 can be operated freely; and after the reset spring 16 is compressed, the convex plate 19 is connected by the clamping plate 18. At this time, the limiting rod 15 drives the support plate 17 and the driving wheel 14 to move downward.

[0031] The driving wheel 14 and the rotating shaft 13 are connected, and the driving wheel 14 can only move along the axis of the rotating shaft 13, but cannot rotate relative to the driving wheel 14. Therefore, after the driving wheel 14 rotates, the rotating shaft 13 can be driven to rotate, thereby realizing the folding and swinging operation of the mirror carrier 1.

[0032] See also Figure 2 and Figure 3The electric element 3 includes a micro motor 31 and a rack seat 32, and the micro motor 31 is connected to the control switch through a wire. The output shaft of the micro motor 31 is threadedly connected to the rack seat 32, and the rack seat 32 is slidably connected to the car body, and the rack seat 32 is meshed with the driving wheel 14. The micro motor 31 is arranged below the rotating shaft 13, and the output shaft of the micro motor 31 is perpendicular to the center line of the rotating shaft 13. After the micro motor 31 is turned on, the rack seat 32 can move along the center line direction of the output shaft of the micro motor 31. Through the meshing action of the rack seat 32 and the driving wheel 14, during the movement of the rack seat 32, the driving wheel 14 rotates, which can provide a rotational driving force to the rotating shaft 13, thereby allowing the rearview mirror to swing and fold, and realize automatic swinging operation.

[0033] Working principle: When the power is on, the driving component of the rearview mirror folding mechanism can turn on the micro motor 31 by controlling the switch. After the micro motor 31 is turned on, the rack seat 32 can move along the center line direction of the output shaft of the micro motor 31. Through the meshing action of the rack seat 32 and the driving wheel 14, during the movement of the rack seat 32, the driving wheel 14 rotates, which can provide a rotational driving force to the rotating shaft 13, thereby allowing the rearview mirror to swing and fold, thereby realizing automatic swinging operation; when the power is not on, the limit rod 15 is rotated to drive the convex plate 19 to rotate in a ring shape. At this time, the upper and lower positions of the convex plate 19 and the clamping plate 18 are staggered. After the limit rod 15 is released from the restriction, the reset spring 16 is set to enable the limit rod 15 to move upward in the initial state. In this state, the support plate 17 and the driving wheel 14 can be operated freely, so that after the power is off, the driving wheel 14 and the rack seat 32 can be separated, which is convenient for the manual folding operation of the rearview mirror.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
