Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rearview mirror adjustment, in particular to a steering adjustment adapter for automobile rearview mirror and an adjustment method. BACKGROUND

[0002] As a vital safety component of a vehicle, the convenience and accuracy of the angle adjustment of the automobile rearview mirror are directly related to the safety of the driver's field of view and the driving experience. For a long time, the steering adjustment of the automobile rearview mirror mainly relies on a mechanical transmission structure. The core working principle of the traditional adjustment device is to install two sets of driving units in the rearview mirror shell, which are usually driven by a small motor. The rotary motion is converted into linear motion through a worm and gear or a gear set. The execution component of this linear motion is generally a push rod with telescopic function or a similar structure composed of a threaded sleeve and a threaded rod. Specifically, by controlling the forward and reverse rotation of the motor, the threaded rod is rotated in or out of the threaded sleeve, or the telescopic rod is extended or shortened, so that the rearview mirror is pushed or pulled at the end, thereby realizing the angle adjustment of the rearview mirror in the pitch and yaw directions.

[0003] However, this traditional structure has two significant inherent defects in actual application. First, it requires a large installation space. Whether it is the stroke range of the telescopic rod or the longitudinal space occupied by the threaded sleeve and the threaded rod after being completely rotated out, it requires that the rearview mirror shell have sufficient depth and width. This is contrary to the current trend of pursuing streamline, lightweight and miniaturization in automobile design, which limits the spatial optimization of the rearview mirror design. Second, its telescopic range is small. Due to structural limitations, the effective stroke of the push rod or the threaded rod is limited, which directly restricts the maximum adjustment angle of the rearview mirror, resulting in insufficient observable field of view of the rearview mirror, which easily affects the safe driving of the vehicle.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] Example 1: like Figures 1 to 4 As shown, this application provides a car rearview mirror steering adjustment adapter, including a mirror holder 100, a base 200, an adjustment unit 300 and a support unit 400. The support unit 400 is used to connect the mirror holder 100 and the base 200, and the adjustment unit 300 is used to adjust the tilt angle and tilt direction of the mirror holder 100 on the base 200. The adjustment unit 300 includes a first rotating ring 301, a second rotating ring 302, and a second adjustment motor 305. The first rotating ring 301 and the second rotating ring 302 are coaxial and rotatably mounted on the mirror holder 100 and the base 200, respectively. The first rotating ring 301 and the second rotating ring 302 are rotatably connected by a slanted arm 303. The second rotating ring 302 is provided with an adjustment motor 304 for providing power for the rotation of the slanted arm 303. The base 200 is provided with an adjustment motor 305 for providing power for the rotation of the second rotating ring 302 and a transmission wheel 306.

[0022] Specifically, the rearview mirror and the base 200 can be fixed on the mirror holder 100 and the rearview mirror shell by means of bolts, clamps, etc., or connected to corresponding structures by means of pasting, and the support unit 400 is located between the mirror holder 100 and the base 200 and is used to connect the mirror holder 100 and the base 200. The support unit 400 can be a traditional movable connecting rod or other structure. Since the mirror holder 100 needs to move on the base 200, the support of the support unit 400 to the mirror holder 100 will not interfere with the movement of the mirror holder 100. Specifically, the support unit 400 can be a universal joint or a multi-support rod combined structure, as long as it can allow the rearview mirror to tilt in any direction, but it cannot rotate the rearview mirror.

[0023] The adjusting unit 300 is the main power structure for adjusting the rearview mirror. The rotating ring one 301 is rotatably installed on the back side of the mirror holder 100, the rotating ring two 302 is rotatably installed on the base 200, and the inclined arm 303 connects the rotating ring one 301 and the rotating ring two 302. The connection relationship between the inclined arm 303 and the rotating ring one 301 and the rotating ring two 302 is all rotary connection. The two ends of the inclined arm 303 are separated from each other in the circumferential direction of the rotating ring one 301, and the range occupied by the inclined arm 303 in the circle where the rotating ring one 301 is located is less than half a circle. In this way, when the inclined arm 303 rotates on the rotating ring two 302, the projection distance of the inclined arm 303 in the axial direction of the rotating ring one 301 will change, thereby using the change of the projection length of the inclined arm 303 to lift one side of the rotating ring one 301. The rotating ring one 301 will push the mirror holder 100 and the rearview mirror to tilt synchronously, achieving the purpose of adjusting the tilt angle of the rearview mirror. It should be noted that since the angle between the inclined arm 303 and the rotating ring one 301 changes synchronously when the inclined arm 303 rotates on the rotating ring two 302, the rotating ring one 301 will rotate on the mirror holder 100. In order to avoid the rotating ring one 301 driving the rearview mirror to rotate synchronously, the mirror holder 100 and the rearview mirror need to be limited by the support unit 400, so that the rearview mirror only performs tilting movement. By using the inclined arm 303 to connect the rotating ring one 301 and the rotating ring two 302, the inclined arm 303 only occupies part of the interval of the circle where the rotating ring one 301 is located, whether in the dumping state or in the tilting state. This can greatly save installation space and make the overall structure smaller in thickness and volume.

[0024] The adjusting motor one 304 is relatively fixed with the rotating ring two 302 and can provide power for the tilting rotation of the inclined arm 303; the adjusting motor two 305 is relatively fixed with the base 200, the transmission wheel 306 is installed on the output end of the adjusting motor two 305, and the transmission wheel 306 is in transmission connection with the rotating ring two 302, so that when the adjusting motor two 305 and the transmission wheel 306 drive the rotating ring two 302 to rotate, the inclined arm 303 will synchronously drive the rotating ring one 301 to rotate, the position of the inclined arm 303 in the circumferential direction of the rotating ring one 301 changes, and the position of the inclined arm 303 pushing the rearview mirror changes, so as to adjust the tilting position of the rearview mirror, and the adjustment of the tilting angle and the tilting position of the rearview mirror is realized.

[0025] Through the technical scheme of the present application, the problems of large structure size and large space occupation are effectively solved, because when the inclined arm 303 is retracted, the space occupation amount of the inclined arm 303 in the longitudinal direction of the rearview mirror is only the width of the inclined arm 303 itself, so it only needs a small installation space, which can effectively reduce the depth and width of the rearview mirror shell; because the tilting angle of the rearview mirror is directly adjusted by the tilting rotation of the inclined arm 303, the maximum adjustment angle of the rearview mirror is associated with the length of the inclined arm 303, the active range of the rearview mirror is effectively increased, and the observable field of view of the driver is conveniently increased.

[0026] Further, because the tilting movement of the inclined arm 303 drives the rotating ring one 301 to rotate, the two ends of the inclined arm 303 have relative displacement in the circumferential direction of the rotating ring one 301, the axial direction of the rotating ring one 301, and the radial direction of the rotating ring one 301, and the traditional integrated structure cannot meet the above movement requirements, which is easy to cause the mutual jamming of the rotating ring one 301 and the rotating ring one 301, so the inclined arm 303 needs to be specially set, specifically, as shown in the figure, Figure 4 The inclined arm 303 includes a long rod 307, two connecting bodies one 308 rotatably arranged at the two ends of the long rod 307, and two connecting bodies two 309 rotatably connected with the two connecting bodies one 308, respectively, the two connecting bodies two 309 are fixed on the rotating ring one 301 and the rotating ring two 302, respectively, the rotation axis between the long rod 307 and the connecting body one 308 is parallel to the axis of the rotating ring one 301, and the rotation axis between the connecting body one 308 and the connecting body two 309 is perpendicular to the axis of the rotating ring one 301; In the circumferential direction of the rotating ring one 301, the positions of the two connecting bodies two 309 are staggered, and the adjusting motor one 304 provides rotation power for one connecting body two 309.

[0027] An adjusting motor 304 is mounted on a connecting body 309 and provides rotational power to a connecting body 308 on the connecting body 309. This causes the connecting body 308 to rotate a long rod 307. The long rod 307 gradually rotates from a tilted state parallel to the rotating ring 302 to an inclined state. The projected length of the long rod 307 along the axis of the rotating ring 301 increases. This causes the long rod 307 to push one side of the rotating ring 301 upward through the connecting body 309 and the connecting body 308 on the rotating ring 301, so that the rearview mirror is in an inclined state. The two connecting bodies 309 are close to each other in the circumferential direction of the rotating ring 301. The long rod 307 rotates relative to the connecting body 308, and the connecting body 308 rotates relative to the connecting body 309.

[0028] Furthermore, the support unit 400 includes a U-shaped frame 401 fixed on the base 200 and two curved rods 402 rotatably mounted at both ends of the U-shaped frame 401. A ball 403 is provided between the two curved rods 402, and the ball 403 is rotatably connected to the curved rods 402. The rotation axis of the ball 403 coincides with that of the two curved rods 402. The rotation axis of the two curved rods 402 on the U-shaped frame 401 coincides with that of the curved rods 402. The rotation axis of the ball 403 on the curved rods 402 is perpendicular to the rotation axis of the curved rods 402 on the U-shaped frame 401. The sphere 403 is connected to the mirror holder 100 via a connecting rod 404.

[0029] like Figure 5 As shown, the bottom of the U-shaped frame 401 can be fixed to the base 200. The two ends of the U-shaped frame 401 face each other, and the two end faces of the curved rod 402 are perpendicular to each other. One end face of the curved rod 402 is rotatably mounted on the U-shaped frame 401, and the rotation axes of the two curved rods 402 at that end coincide. The other end face of the curved rod 402 is rotatably connected to the ball 403, and the rotation axes of the two curved rods 402 at that end coincide. When the ball 403 and its connecting rod 404 rotate to the left or right in the lateral direction, the ball... The ball 403 rotates on the two cranks 402. When the ball 403 and its connecting rod 404 rotate forward or backward in the longitudinal direction, the two cranks 402 rotate on the U-shaped frame 401. When the ball 403 and its connecting rod 404 rotate at an angle, the ball 403 rotates on the cranks 402, and the cranks 402 rotate synchronously on the U-shaped frame 401. Thus, this structure is used to support the rearview mirror and restrict the rearview mirror to tilting motion only, without rotational motion.

[0030] Further, the U-shaped frame 401 is provided with a clamping structure for locking the position of the ball 403, the clamping structure comprising a fixing hole 408 formed on the U-shaped frame 401, a spring 405 and a top column 406 located in the fixing hole 408, the spring 405 being used to connect the top column 406 and the U-shaped frame 401, the end of the top column 406 extending out of the fixing hole 408, the bottom of the ball 403 being provided with a spherical buckle plate 407, and the spherical buckle plate 407 being connected with the top column 406.

[0031] As shown in Figure 5 , the fixing hole 408 is formed at the bottom of the ball 403, and the axis of the fixing hole 408 coincides with the center of the ball 403, the spring 405 is installed in the fixing hole 408, and the spring 405 can provide an elastic thrust for the top column 406, part of the top column 406 sliding in the fixing hole 408, at this time the fixing hole 408 can guide the top column 406 synchronously, thereby guiding the spherical buckle plate 407, the thrust provided by the top column 406 for the spherical buckle plate 407 makes the spherical buckle plate 407 adhere to the bottom of the ball 403, thereby limiting the ball 403 by using the friction force, that is, after the rearview mirror is completed, the spherical buckle plate 407 can limit the rearview mirror from moving, at this time the adjusting unit 300 is powered off, the purpose of this is to avoid the need to use the adjusting motor one 304 and the adjusting motor two 305 in the adjusting unit 300 to limit the orientation of the rearview mirror.

[0032] Further, as shown in Figure 3 , the mirror holder 100 comprises a holder ring 101 and a holder table 102, the holder ring 101 being sleeved on the holder table 102, and the inclination angle of the holder ring 101 on the holder table 102 being adjustably arranged, that is, the holder ring 101 can be inclined and rotated on the holder table 102.

[0033] By adopting the combination of the holder ring 101 and the holder table 102, the mirror holder 100 can allow manual adjustment of the rearview mirror, thereby realizing a dual adjustment mode of automatic adjustment and manual adjustment, avoiding damage to the internal structure of the rearview mirror caused by manually pulling the rearview mirror when only the automatic adjustment mode is adopted, and facilitating protection of the rearview mirror.

[0034] Further, the holder table 102 is provided with four fixing grooves 103, and the four fixing grooves 103 are distributed in a quadrilateral shape, each fixing groove 103 being provided with a guide sleeve 104, and the arc-shaped sliding arm 105 being slidingly inserted into the guide sleeve 104; One of the two adjacent guide sleeves 104 is fixed on the inner wall of the corresponding fixed groove 103, and the arc-shaped sliding arm 105 on the guide sleeve 104 is rotatably arranged on the supporting ring 101 through the connecting shaft 108, and the other guide sleeve 104 is rotatably arranged on the inner wall of the corresponding fixed groove 103 through the rotating column 106 and the connecting disc 107, and the arc-shaped sliding arm 105 on the guide sleeve 104 is fixedly connected with the supporting ring 101. The rotation axes of the two rotating columns 106 coincide, the rotation axes of the two connecting shafts 108 coincide, and the four arc-shaped sliding arms 105 are on the same spherical surface.

[0035] The supporting ring 101 can be used to install a rearview mirror, and the supporting table 102 is connected with the adjusting unit 300 and the supporting unit 400.

[0036] As shown in Figures 6 to 8 the four fixed grooves 103 are all arranged on the outer wall of the supporting table 102 near the back side, and the four fixed grooves 103 and the four guide sleeves 104 in them are in quadrilateral distribution, so that the supporting ring 101 will not be stuck during movement, the arc-shaped sliding arm 105 is inserted in the guide sleeve 104, and the four arc-shaped sliding arms 105 are on the same spherical surface, so that the four guide sleeves 104 and the four arc-shaped sliding arms 105 can support the supporting ring 101 while allowing the supporting ring 101 to tilt on the supporting table 102, and the supporting ring 101 will not rotate on the supporting table 102, thereby realizing the guiding of the supporting ring 101. Taking the rotating axis of the rotating column 106 as the reference axis, when the supporting ring 101 tilts, the supporting ring 101 will drive the connecting shaft 108 and the arc-shaped sliding arm 105 thereon to slide in the corresponding guide sleeve 104, that is, one of the arc-shaped sliding arms 105 corresponding to the two connecting shafts 108 slides out of the corresponding guide sleeve 104, and the other arc-shaped sliding arm 105 slides in the corresponding guide sleeve 104. At the same time, the supporting ring 101 drives the rotating column 106, the corresponding guide sleeve 104 and the arc-shaped sliding arm 105 to rotate around the axis of the rotating column 106. When it is needed to rotate the supporting ring 101 on the connecting shaft 108 on this basis, the arc-shaped sliding arm 105 on the rotating column 106 is only needed to slide in the corresponding guide sleeve 104, and at this time the supporting ring 101 rotates relative to the corresponding arc-shaped sliding arm 105 through the connecting shaft 108, thereby realizing the adjustment of the supporting ring 101.

[0037] It should be noted that during the above movement process, when the rotating column 106 rotates, the arc-shaped sliding arm 105 thereon will tilt synchronously, thereby allowing the subsequent supporting ring 101 to rotate around the axis of the connecting shaft 108, avoiding the sticking phenomenon.

[0038] Further, since the setting of the supporting ring 101 and the supporting table 102 allows the rearview mirror to be adjusted manually, after the adjustment is completed, in order to limit the position of the rearview mirror and avoid its random movement, the structure between the supporting ring 101 and the supporting table 102 needs to be specially set. Specifically, the arc-shaped sliding arm 105 is provided with teeth, and the guide sleeve 104 is provided with an elastic body 110 matched with the teeth on the arc-shaped sliding arm 105; the elastic force of the elastic body 110 is used to limit the clamping of the teeth on the arc-shaped sliding arm 105, so as to avoid the random sliding of the arc-shaped sliding arm 105 on the guide sleeve 104, and facilitate the limitation of the supporting ring 101 and the rearview mirror.

[0039] Further, the guide sleeve 104 is provided with an installation groove 109, the opening of the installation groove 109 is towards the side wall of the arc-shaped sliding arm 105, and the opening shape of the installation groove 109 is a taper towards the inside of the installation groove 109, and the installation groove 109 is provided with a clamping column 111. The elastic body 110 is located in the installation groove 109, and the elastic body 110 includes two arc-shaped elastic sheet areas 112 and two arc-shaped clamping areas 113. One end of the two arc-shaped elastic sheet areas 112 is mutually connected and used to match with the adjacent two teeth on the arc-shaped sliding arm 105, and the two arc-shaped clamping areas 113 are respectively located at the other end of the two arc-shaped elastic sheet areas 112, and the two arc-shaped clamping areas 113 are matched with the clamping column 111.

[0040] The two arc-shaped elastic sheet areas 112 form a taper, and the end part thereof can extend out of the installation groove 109 and be clamped between the adjacent two teeth on the arc-shaped sliding arm 105. Combined with the shape of the two arc-shaped elastic sheet areas 112 and the shape of the installation groove 109, when the arc-shaped sliding arm 105 slides, the teeth on the arc-shaped sliding arm 105 push the two arc-shaped elastic sheet areas 112 to bend and deform towards the inside of the installation groove 109, so as to realize the staggered tooth movement and realize the clamping locking effect of the elastic body 110 on the different teeth on the arc-shaped sliding arm 105, and the shape of the installation groove 109 can provide space for the deformation of the two arc-shaped elastic sheet areas 112; the two arc-shaped clamping areas 113 can be clamped on the clamping column 111 by using the elastic force of the two arc-shaped clamping areas 113 and the elastic force of the arc-shaped elastic sheet areas 112, so as to realize the fixation of the elastic body 110; in actual use, the elastic body 110 can be directly inserted into the installation groove 109, and the clamping column 111 is reversely expanded to separate the two arc-shaped clamping areas 113 and clamp the two arc-shaped clamping areas 113 on the clamping column 111, so as to realize the quick installation of the clamping column 111.
