Description

Technical Field

[0001] This invention relates to the field of automotive rearview mirror technology, specifically to a multi-clutch controlled automotive rearview mirror bracket and rearview mirror system. Background Technology

[0002] With the development and application of technology, existing car rearview mirrors can fold down when in narrow road sections, when meeting oncoming traffic, or when parking, reducing the width of the vehicle, lowering the risk of scratches, and preventing the mirror surface from being scratched and the bracket from breaking upon impact.

[0003] Specifically, a drive motor is usually installed inside the rearview mirror bracket. The drive motor drives the rearview mirror to rotate, thereby folding and unfolding the rearview mirror. However, in some special areas with low ambient temperature, the gap between the rearview mirror and the bracket is prone to sticking due to ice formation. At this time, the drive motor not only needs to provide the power to rotate the rearview mirror, but also needs to provide additional power to overcome the sticking force caused by the ice, resulting in a large starting current of the drive motor.

[0004] Furthermore, after the drive motor rotates the rearview mirror and breaks the adhesive force caused by the ice, there are still ice fragments in the gap between the rearview mirror and the bracket, which makes the rotational resistance of the rearview mirror still very large. The drive motor is always in a working environment with a large load, which can easily lead to the burnout of the internal coil of the drive motor and affect the service life of the drive motor. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-clutch controlled automotive rearview mirror bracket and rearview mirror system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: Multi-clutch controlled car rearview mirror bracket, including: The stent body has a hysteresis cavity formed within it; A rotating sleeve rod is slidably disposed through the hysteresis cavity, and one end of the rotating sleeve rod is connected to the support body through a clutch structure; A power component is detachably installed within the hysteresis cavity, and a convex shaft is formed on the power component; An elastic retaining assembly is connected to the rotating sleeve rod. A follower sleeve is connected to the elastic retaining assembly. The follower sleeve cooperates with the cam shaft to keep the clutch structure in an engaged state. The misaligned structure connects to the power component, and the misaligned structure can drive the rotating sleeve to rotate after the clutch structure is disengaged.

[0007] As a further aspect of the present invention: the clutch structure includes an upper clutch component connected to the rotating sleeve rod and a lower clutch component fixedly installed on the bracket body. Both the upper clutch component and the lower clutch component are circumferentially equidistant and alternately provided with protrusions and recesses, and the protrusions provided on the upper clutch component are adapted to the recesses provided on the lower clutch component.

[0008] As a further embodiment of the present invention: the protrusion and the two adjacent sets of recesses are connected by two sets of symmetrical inclined surfaces. When the upper clutch rotates relative to the lower clutch, the two sets of inclined surfaces provided on the upper clutch and the lower clutch and in contact with each other can slide relative to each other, so that the upper clutch moves away from the lower clutch.

[0009] As a further embodiment of the present invention: the hysteresis cavity can be inserted into a bottom support member that slides with it, and the bottom support member is provided with a locking pin on its side, the locking pin being adapted to a locking groove provided on the side of the hysteresis cavity.

[0010] As a further embodiment of the present invention: the power component includes a drive motor connected to the bottom support component, and the output shaft of the drive motor is connected to the misaligned structure; The output shaft of the drive motor is also provided with a connecting ring, and the convex shaft is fixed on the outer circumference of the connecting ring.

[0011] As a further embodiment of the present invention: the elastic retaining assembly includes a connecting plate fixedly installed in the hysteresis cavity and a connecting rod rotatably connected to the rotating sleeve rod. The connecting rod is slidably disposed through the connecting plate, and a cylindrical spring is sleeved on the connecting rod. One end of the cylindrical spring is connected to the end of the connecting rod, and the other end is connected to the connecting plate. The end of the connecting rod away from the rotating sleeve is fixedly connected to the follower sleeve.

[0012] As a further embodiment of the present invention: the follower sleeve is provided with a drive groove, and the convex shaft can roll within the drive groove; The drive groove includes an arc-shaped groove arranged along the circumferential direction of the follower sleeve and a spiral groove arranged along the axial direction of the follower sleeve. The spiral groove is provided in two sets and connects the beginning and end of the arc-shaped groove. When the convex shaft moves along the spiral groove, it can drive the follower sleeve to move upward.

[0013] As a further embodiment of the present invention: the misaligned structure includes: A rotating shaft rotatably connected to the connecting plate, one end of which is slidably fitted with the rotating sleeve rod; A follower disk is coaxially and fixedly connected to one end of the rotating shaft away from the rotating sleeve rod. The bottom of the follower disk is provided with an arc groove, and the fitting shaft that is eccentrically connected to the output shaft of the power component can slide in the arc groove.

[0014] As a further embodiment of the present invention: the rotating shaft is provided with a limiting groove along its length direction, and the limiting groove is slidably fitted with a limiting block provided on the inner wall of the rotating sleeve.

[0015] A rearview mirror system, including the aforementioned multi-clutch controlled automotive rearview mirror bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By designing a clutch mechanism, firstly, when the rearview mirror and its bracket body stick together due to ice, manually turning the rearview mirror allows the upper and lower clutch components to rotate relative to each other and separate, thus breaking the sticking force caused by ice from multiple angles and quickly eliminating the sticking. Secondly, when an external force is applied to the rearview mirror, the inclined surfaces on the upper and lower clutch components can slide against each other, allowing the rearview mirror to unfold or retract, effectively buffering the external force and preventing damage or breakage of the rearview mirror caused by the absolute locking of the rearview mirror's pivot when external forces are applied. By designing the drive groove, convex shaft, and staggered structure, the rearview mirrors, along with the upper clutch, are lifted upwards when the drive motor rotates them, creating an upward pulling effect. This breaks the adhesion between the rearview mirror and the bracket body caused by ice, reducing resistance during subsequent rotation. Furthermore, it prevents interference between the upper and lower clutches, thus reducing the tendency for the rearview mirror to move up and down, further lowering the load on the drive motor when rotating the mirrors. It also prevents the mirrors from shaking due to vertical movement, improving their stability. Simultaneously, the staggered lifting and rotating of the rearview mirrors by the drive motor ensures efficient utilization of its output power, avoiding excessive load caused by simultaneously rotating and raising the mirrors, thus improving the drive motor's durability.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0028] Please see Figures 1-8In this embodiment of the invention, the multi-clutch controlled rearview mirror bracket includes: a bracket body 1, a rotating sleeve 9, a power component, an elastic retaining component, and a misalignment structure.

[0029] A hysteresis cavity 101 is formed inside the support body 1; The rotating sleeve 9 is slidably disposed through the hysteresis cavity 101. One end of the rotating sleeve 9 is connected to the bracket body 1 through a clutch structure. The top of the rotating sleeve 9 is provided with a toothed shaft 15. The car rearview mirror is connected to the toothed shaft 15 by bolts. The car rearview mirror is provided with a toothed groove that matches the toothed shaft 15. When the toothed shaft 15 is inserted into the toothed groove, the top of the toothed shaft 15 can be inserted into the interior of the car rearview mirror. At this time, the bolts are tightened to ensure a stable connection between the rotating sleeve 9 and the car rearview mirror, and to ensure that the rearview mirror can rotate synchronously with the rotating sleeve 9, thereby ensuring the rotation accuracy of the rearview mirror and preventing situations such as incomplete rotation or excessive rotation.

[0030] The clutch structure includes an upper clutch 12 connected to the rotating sleeve 9 and a lower clutch 13 fixedly installed on the bracket body 1. Both the upper clutch 12 and the lower clutch 13 are circumferentially equidistant and alternately provided with protrusions and recesses. The protrusions on the upper clutch 12 are adapted to the recesses on the lower clutch 13. Specifically, the protrusions and two adjacent sets of recesses are connected by two sets of symmetrical inclined surfaces 14. When the upper clutch 12 rotates relative to the lower clutch 13, the two sets of inclined surfaces 14 provided on the upper clutch 12 and the lower clutch 13 and in contact with each other can slide relative to each other, so that the upper clutch 12 moves away from the lower clutch 13.

[0031] In the initial state, under the pull of the elastic retaining assembly, the upper clutch 12 and the lower clutch 13 are engaged. Specifically, this engagement means that the protrusion on the upper clutch 12 is located within the recess of the lower clutch 13, and the inclined surface 14 between adjacent protrusions and recesses on the upper clutch 12 and the inclined surface 14 between adjacent protrusions and recesses on the lower clutch 13 are in contact. In this state, firstly, the stability of the rearview mirror in its unfolded or folded state is ensured; secondly, when an external force is applied to the rearview mirror, the inclined surfaces 14 on the upper clutch 12 and the lower clutch 13 can slide relative to each other, allowing the rearview mirror to unfold or fold, thus achieving the aforementioned... The external force is effectively buffered, preventing damage or breakage of the rearview mirror caused by the absolute locking of the rearview mirror's pivot when external force is applied to the rearview mirror. At the same time, when the external temperature is very low and the rearview mirror and the bracket are stuck together due to ice, and the folding and unfolding actions cannot be completed by the motor alone, the upper clutch 12 and the lower clutch 13 tend to rotate relative to each other when the rearview mirror is manually pried open. With the cooperation of the two sets of inclined surfaces 14, the rearview mirror can move upward relative to the bracket body 1, thereby breaking the sticking force caused by ice from multiple angles (including rotational force and upward pulling force), so that the sticking caused by ice can be quickly eliminated.

[0032] Furthermore, compared to the traditional method of forcibly rotating the rearview mirror to break the adhesive force between the rearview mirror and the bracket body 1, this application also generates an upward force from the rearview mirror during the forced rotation process. In this process, the upward force generated by the rearview mirror is equivalent to axial peeling, which to a certain extent overcomes the tensile strength of ice, makes it easier to break the freezing point, and reduces the initial resistance.

[0033] Please see Figure 3 The power component is detachably installed in the hysteresis cavity 101. A convex shaft 401 is formed on the power component. The hysteresis cavity 101 can be inserted into the bottom support 2 that slides with it. The bottom support 2 is provided with a locking pin 201 on its side. The locking pin 201 is adapted to the locking groove 102 provided on the side of the hysteresis cavity 101.

[0034] The power component includes a drive motor 3 connected to the bottom support 2, and the output shaft of the drive motor 3 is connected to the misaligned structure; Considering the special nature of the automotive operating environment, in areas with low ambient temperatures, the rearview mirror and the bracket body 1 often experience icing and adhesion. In this case, the initial load on the motor when driving the rearview mirror to fold and unfold is very large. Although there is an overload protection circuit, the motor still experiences a large load at startup, which can lead to motor burnout. In this embodiment, when the motor burns out, the bottom support 2 can be removed by pressing the latch 201 and pulling the bottom support 2 downward, thereby enabling convenient replacement of the motor and reducing operating costs.

[0035] Please see Figures 1-8 The elastic retaining component is connected to the rotating sleeve 9, and a follower sleeve 6 is connected to the elastic retaining component. The follower sleeve 6 cooperates with the convex shaft 401 to keep the clutch structure in an engaged state. The elastic retaining assembly includes a connecting plate 16 fixedly installed in the hysteresis cavity 101 and a connecting rod 7 rotatably connected to the rotating sleeve rod 9. The connecting rod 7 is slidably disposed through the connecting plate 16, and a cylindrical spring 8 is sleeved on the connecting rod 7. One end of the cylindrical spring 8 is connected to the end of the connecting rod 7, and the other end is connected to the connecting plate 16.

[0036] In the initial state, the cylindrical spring 8 is in a stretched state. In this state, the cylindrical spring 8 has a tendency to pull the rotating sleeve 9 downward, thereby ensuring the engagement state between the upper clutch 12 and the lower clutch 13, ensuring the stability of the rearview mirror in the folded and unfolded state, and at the same time making the rearview mirror have a certain buffering effect against external forces.

[0037] Please see Figure 3 , Figure 8 The output shaft of the drive motor 3 is also provided with a connecting ring 4, and the convex shaft 401 is fixed on the outer circumference of the connecting ring 4; The end of the connecting rod 7 away from the rotating sleeve 9 is fixedly connected to the follower sleeve 6; The follower sleeve 6 is provided with a drive groove, and the convex shaft 401 can roll in the drive groove; The drive groove includes an arc-shaped groove 601 arranged along the circumferential direction of the follower sleeve 6 and a spiral groove 602 arranged along the axial direction of the follower sleeve 6. The spiral groove 602 is provided in two sets and connects the beginning and end of the arc-shaped groove 601. When the convex shaft 401 moves along the spiral groove 602, it can drive the follower sleeve 6 to move upward.

[0038] It should be noted that during the process of manually turning the rearview mirror to rotate, the rearview mirror, together with the upper clutch 12, will move upward relative to the lower clutch 13. During this process, the rotating sleeve 9 will drive the follower sleeve 6 to move upward through the connecting rod 7. At this time, the cam shaft 401 can move along the spiral groove 602 to make way for the movement of the follower sleeve 6. Specifically, the length of the spiral groove 602 along the axial direction of the follower sleeve 6 is greater than the rising height of the upper clutch 12 during rotation, so that when the upper clutch 12 returns to its original position and is in contact with the lower clutch 13, the cam shaft 401 can return to the end of the spiral groove 602.

[0039] In use, when the drive motor 3 rotates to actively drive the rearview mirror to fold, the connecting ring 4 connected to the output shaft of the drive motor 3 will rotate and drive the cam shaft 401 to make a circular motion. During this process, the cam shaft 401 will move along the length direction of the spiral groove 602 and cause the follower sleeve 6 to move upward. At this time, the follower sleeve 6 drives the upper clutch 12 and the rearview mirror to move upward through the connecting rod 7 and the rotating sleeve 9. When the cam shaft 401 moves from the spiral groove 602 into the arc groove 601, the upper clutch 12 can completely separate from the lower clutch 13. At this time, under the action of the misaligned structure, the rotating sleeve 9 can rotate and drive the rearview mirror to rotate. After rotating to the position, the cam shaft 401 moves into the spiral groove 602 at the other end of the arc groove 601, causing the upper clutch 12 and the rearview mirror to move downward, so as to achieve elastic locking of the rearview mirror with the cooperation of the upper clutch 12 and the lower clutch 13.

[0040] Based on the above configuration, the rearview mirror can be lifted upwards along with the upper clutch 12 before rotation. That is, before rotating the rearview mirror, the rearview mirror and the upper clutch 12 are pulled upwards. This can break the adhesion between the rearview mirror and the bracket body 1 caused by ice, thus reducing the resistance during the subsequent rotation of the rearview mirror. On the other hand, during the upward movement, the upper clutch 12 can be completely misaligned with the lower clutch 13, so that during rotation, there will be no interference between the upper clutch 12 and the lower clutch 13, and no tendency to drive the rearview mirror to move up and down. This further reduces the load on the drive motor 3 when driving the rearview mirror to rotate, and at the same time avoids the rearview mirror from shaking due to up and down movement, thus improving the stability of the rearview mirror.

[0041] Please see Figure 4 , Figures 7-8 The misaligned structure is connected to the power component, and the misaligned structure can drive the rotating sleeve 9 to rotate after the clutch structure is disengaged; The misaligned structure includes: A rotating shaft 10 is rotatably connected to the connecting plate 16. One end of the rotating shaft 10 is slidably fitted with the rotating sleeve rod 9. Specifically, the rotating shaft 10 is provided with a limiting groove 1001 along its length direction. The limiting groove 1001 is slidably fitted with a limiting block 901 provided on the inner wall of the rotating sleeve rod 9. A follower disk 11 is coaxially fixedly connected to one end of the rotating shaft 10 away from the rotating sleeve rod 9. The bottom of the follower disk 11 is provided with an arc groove 1101. The fitting shaft 5, which is eccentrically connected to the output shaft of the power component, can slide in the arc groove 1101.

[0042] In the initial state, the fitting shaft 5 is located at one end of the arc groove 1101. During use, when the output shaft of the drive motor 3 rotates and the cam 401 moves along the spiral groove 602 into the arc groove 601, the fitting shaft 5 is in a sliding state within the arc groove 1101. That is, during the initial operation of the drive motor 3, its output power is only used to generate an upward lifting force on the rearview mirror and the upper clutch 12. When the cam 401 moves into the arc groove 601, the fitting shaft 5 moves to the end of the arc groove 1101. At this time, the power output of the drive motor 3 is only responsible for driving the rearview mirror to rotate, thus making effective use of the power output of the drive motor 3. This avoids excessive load caused by the drive motor 3 simultaneously driving the rearview mirror to rotate and rise during operation, thereby improving the durability of the drive motor 3 to a certain extent.

[0043] It should be noted that, taking the maximum rotation angle of the rearview mirror as 90° as an example, the arc of the two sets of spiral grooves 602 and arc grooves 601 is 180°, and the arc of the circular groove 1101 is 90°. With this setting, during the first 90° rotation of the output shaft of the drive motor 3, the convex shaft 401 can move from the spiral groove 602 to the arc groove 601. In the subsequent 90° rotation, the fitting shaft 5 can abut against the other side of the circular groove 1101 and thereby drive the rotating shaft 10 to rotate 90°, thus realizing the folding and unfolding action of the rearview mirror. In this state, when the rearview mirror is manually bent to a certain angle, when the drive motor 3 actively drives the rearview mirror to move, the rearview mirror can still unfold and fold to the predetermined angle.

[0044] As an embodiment of the present invention, a rearview mirror system is also proposed, including the aforementioned multi-clutch controlled automotive rearview mirror bracket.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
