Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an adjustment device for a vehicle rearview unit. Background Technology

[0002] The rearview mirror unit is foldable or unfoldable relative to the vehicle body, and this pivoting is usually achieved through the folding mechanism of the rearview mirror unit. The flip mechanism of the rearview mirror unit is a device used to control the flipping of the rearview mirror unit. The flipping of the rearview mirror unit is achieved through manual operation or electric control, allowing the mirror to be rotated to a suitable angle. This can be adjusted to a suitable position according to different drivers' driving habits, improving driving safety. The flip mechanism does not exist independently; it needs to cooperate with the folding mechanism to achieve the adjustment of the rearview mirror unit. This makes the structure of the entire rearview mirror adjustment part relatively complex. Currently, the flip mechanisms used in the market suffer from insufficient operational stability and large size, which to some extent limits the overall design and aesthetic optimization of the rearview mirror.

[0038] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0039] Please refer to Figures 1-9 A flipping mechanism for a vehicle rearview unit includes a first shaft, a hinge, and a second shaft connected sequentially along the axial direction.

[0040] The first shaft and the second shaft are coaxially arranged. The hinge has an arc-shaped portion, which has a first arc surface and a second arc surface arranged opposite to each other. The arc-shaped portion is provided with a first through hole penetrating the first arc surface and the second arc surface. The first shaft, the hinge, and the second shaft are preferably an integral structure.

[0041] As described above, the flipping mechanism drives the vehicle's rearview unit to pivot axially along the first and second shafts. The arc-shaped portion provides a base for relative sliding with other mechanisms, enabling the flipping mechanism to pivot stably. The through hole provides space for the base shaft of the rear folding mechanism to pass through, thus enabling the flipping mechanism to cooperate with the folding mechanism. This flipping mechanism itself has a simple, compact structure and small size, and is easy to assemble with other mechanisms, providing a stable foundation for the flipping of the vehicle's rearview unit.

[0042] Reference Figure 1 and 2 In one or more embodiments, the arcuate portion of the hinge is connected to two shafts via a connecting portion, which is hemispherical in shape.

[0043] In one or more embodiments, the first and second shafts are provided with blind holes along the axial direction, and a reinforcing core is provided within the blind holes. The reinforcing core is made of metal, while the first and second shafts are made of plastic, which helps to reduce costs while increasing the strength of the two shafts. Shafts are provided on both sides of the hinge, which can significantly improve its stability during pivoting.

[0044] In one or more embodiments, the flipping mechanism further includes a flipping base having a third arc surface adapted to the first arc surface, the first arc surface being slidable along the third arc surface, and a second through hole being provided on the third arc surface.

[0045] Reference Figure 3 The flipped base is a hollow hemispherical shape with a third arc surface on its inner sidewall.

[0046] In one or more embodiments, the flipping mechanism further includes a limiting seat having a fourth arc surface adapted to the second arc surface, the second arc surface being slidable along the fourth arc surface, and a third through hole being provided on the fourth arc surface.

[0047] Reference Figure 4The limiting seat includes a base and a semi-cylindrical portion mounted on the base. The side of the semi-cylindrical portion connected to the base is a fourth arc surface, and the semi-cylindrical portion has a saddle-shaped third through hole. The semi-cylindrical portion is fitted inside the arc-shaped portion. The base and the semi-cylindrical portion are preferably an integral structure. During operation, the limiting seat does not rotate, which reduces friction at the contact points between mechanisms and, to a certain extent, limits the rotation angle of the flipping mechanism, allowing it to rotate only within a certain range. The semi-cylindrical portion mentioned in this invention is formed by splitting a cylinder from the middle or near the middle along the axial direction, resulting in a rectangular cross-section.

[0048] An adjustment device for a vehicle rearview unit includes any of the aforementioned flipping mechanisms and a folding mechanism;

[0049] The folding mechanism is used to drive the vehicle's rearview unit to pivot along a first axis; the folding mechanism includes a folding base shaft;

[0050] The tilting mechanism drives the vehicle's rearview unit to pivot along the second axis;

[0051] The folded base shaft is set through the first through hole.

[0052] As described above, the folding mechanism can be any type of mechanism on the market that has a gear assembly and uses a convex-concave structure to fold or unfold the rearview unit, such as the structures shown in patents with application numbers 202110181219.6, 202322570145.2, 202320693543.0, and 202321704064.0. The folding mechanism's axis is typically vertical, while the flipping mechanism's axis is typically horizontal. The two axes can also be at a certain angle to the vertical and horizontal directions respectively, but they are not parallel. The folding mechanism controls the folding or unfolding of the rearview unit, allowing it to move closer to or away from the vehicle body. The flipping mechanism drives the rearview unit to pivot towards or away from the ground, thus achieving "up, down, left, and right" adjustments. During folding, the flipping mechanism rotates along with the rearview unit; during flipping, the folding mechanism does not rotate. The vehicle rearview unit adjustment device provided by this utility model can realize the adjustment of the vehicle rearview unit in multiple directions such as up, down, left and right. At the same time, it has a reasonable design and compact structure. The two mechanisms work together to ensure stable operation and prevent malfunctions.

[0053] In one or more embodiments, the adjusting device further includes a housing, with the ends of the first and second shafts not connected to the hinge extending from the housing. To improve connection stability and smooth pivoting, a bearing is also included, which is sleeved on the first and second shafts and connected to the housing.

[0054] In one or more embodiments, the housing includes an upper housing and a lower housing. The combined housing structure facilitates assembly during production, as well as subsequent disassembly and maintenance.

[0055] In one or more embodiments, the adjusting device further includes a housing with a frustum at the bottom; the housing is disposed on the periphery of the housing above the frustum. The arcuate structure of the frustum provides sufficient clearance for installation and transition between the housing and other parts of the vehicle after installation, preventing collisions between mechanisms during subsequent pivoting.

[0056] In one or more embodiments, a housing is disposed around the outer periphery of the casing and connected to a tilting base shaft. The housing is used to connect the vehicle's rearview unit. During rotation of the tilting base shaft, the housing can rotate, thereby causing the rearview mirror to pivot, thus achieving the effect of tilting the vehicle's rearview unit.

[0057] In one or more embodiments, at least one gasket is fitted onto the folding base shaft, the gasket being located above the flip base and at the point where the folding base shaft passes through the flip base.

[0058] In one or more embodiments, two gaskets are included, one of which is made of metal and the other of plastic.

[0059] In one or more embodiments, the adjusting device further includes a flip actuator and a folding actuator; the flip actuator is drive-connected to the flipping mechanism; and the folding actuator is drive-connected to the folding mechanism.

[0060] In one or more embodiments, the folding actuator includes a first motor and at least one set of first worm gear drives; the folding mechanism is connected to the first motor via the first worm gear drives. The flipping actuator includes a second motor and at least one set of second worm gear drives; the flipping mechanism is connected to the second motor via the second worm gear drives.

[0061] In one or more embodiments, two sets of interconnected second worm gear transmission mechanisms are included. Each second worm gear transmission mechanism includes a worm and a worm wheel coaxially arranged with the worm. The structure of the first worm gear transmission mechanism is the same as that of the second worm gear transmission mechanisms. An incomplete gear is sleeved on a first shaft, and the incomplete gear is connected to one set of second worm gear transmission mechanisms, which in turn is connected to a second motor via another set of second worm gear transmission mechanisms. The folding mechanism itself has a gear structure, and the gear is connected to the first worm gear transmission mechanism, which is connected to the first motor. The operation of the flipping mechanism and the folding mechanism is then controlled by the first and second motors.
