Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to an adaptive adjustment mechanism for a rearview mirror. Background Technology
[0002] The rearview mirror is a tool for the driver to directly obtain external information such as the rear, side and bottom of the vehicle while sitting in the cab seat; traditional rearview mirrors are basically fixed on both sides of the vehicle body, which makes the mirror body of the rearview mirror easy to bump when passing through narrow lanes.
[0003] For this reason, a foldable rearview mirror structure has appeared on the market, which includes a base shell, a mirror body and a servo motor. The base shell is fixed on the car and is equipped with a rotating shaft connected to the mirror body. The servo motor is installed in the base shell and is connected to the connecting shaft to drive the mirror body to fold or unfold. Although this structure can adjust the position of the mirror body to avoid collision, it is more convenient to use.
[0004] However, since the angle adjustment range of the mirror body is directly determined by the rotation stroke of the servo motor, in actual use, if the servo motor exceeds the predetermined stroke or the mirror body is bent by external force, it will cause damage to internal components. In particular, when the mirror body collides with foreign objects, it will cause the entire structure of the electronic rearview mirror to be scrapped and its adaptability is poor.

[0040] Refer to the attached Figure 1 - attached Figure 8 , a rearview mirror adaptive adjustment mechanism, including a mirror body 1, a base shell 2, and a driving part 3; the base shell 2 is installed on the vehicle body of the automobile [not shown in the figure], and an accommodation cavity 20 is provided inside the base shell 2; the driving part 3 includes a driving member 31, a linkage head 32, and a carrier 33; the linkage head 32 is rotatably installed in the accommodation cavity 20, and a rotating hole 321 is provided on the linkage head 32; the driving member 31 is installed in the base shell 2 and is drivingly connected to the linkage head 32; the carrier 33 is rotatably connected to the base shell 2, and a rotating rod 331 is provided on the carrier 33. The rotating rod 331 passes through the accommodation cavity 20 and is in interference fit with the rotating hole 321, so that there is damping between the rotating rod 331 and the linkage head 32; the mirror body 1 is installed on the carrier 33 and is placed outside.
[0041] Specifically, when it is necessary to adjust the rotation angle of the mirror body 1, start the driving member 31 to drive the linkage head 32 to rotate, and rely on the damping between the linkage head 32 and the rotating rod 331 to drive the rotating rod 331 and the carrier 33, so that the mirror body 1 can swing to a suitable position, and then turn off the driving member 31 at this time.
[0042] In the actual use process, there are at least the following scenarios where the mirror body 1 contacts external objects:
[0043] First, when the driving member 31 exceeds a predetermined rotation stroke, it will cause the mirror body 1 to rotate excessively and contact the base shell 2 or the vehicle body. At this time, the base shell 2 or the vehicle body exerts a reaction force on the mirror body 1. When the acting force is greater than the damping force, the linkage head 32 will rotate idly, effectively preventing the mirror body 1 from having a rigid collision.
[0044] Second, during normal driving, if the mirror body 1 collides with an object outside the vehicle, the mirror body 1 will transmit the impact force to the rotating rod 331. When the impact force received by the mirror body 1 is relatively large, the rotating rod 331 will overcome the damping and adaptively rotate around the rotating hole 321, causing the mirror body 1 to avoid the position to prevent a rigid collision with the object.
[0045] Third, when manually swinging the mirror body 1, it is only necessary to ensure that the force applied to the mirror body 1 is greater than the damping force.
[0046] In the above usage scenarios, the mirror body 1 can adaptively rotate to avoid the position, effectively preventing damage to the mirror body 1 and internal parts such as the carrier 33 and the driving member 31.
[0047] In summary, the present utility model designs the linkage head 32 to connect the driving member 31 and the carrier 33, enabling the driving member 31 to adjust the rotation angle of the mirror body 1, improving the convenience of use; by designing the linkage head 32 and the rotating rod 331 of the carrier 33 to be in a rotational interference fit, the mirror body 1 can avoid the position when being knocked by an external object, improving the adaptability, thereby reducing the possibility of overall damage and extending the service life.
[0048] It should be noted that the mirror body 1 in the present utility model can be an electronic vision mirror or an ordinary vision mirror, and there is no limitation here. To reduce the visual blind area and improve the driving safety of the vehicle, an electronic vision mirror is preferably used in this embodiment; the electronic vision mainly consists of a camera and a display screen. Since it is an existing product, the specific structure thereof is not described in the present utility model.
[0049] Refer to the attached Figure 4 - attached Figure 7 and attached Figure 11 - attached Figure 14 Moreover, the present utility model further includes a buffer portion 4. The buffer portion 4 includes a fixed frame 41, a pressing block 42, and an elastic member 43; the fixed frame 41 is located in the accommodating cavity 20, and the top end of the fixed frame 41 penetrates through the accommodating cavity 20 and is fixedly connected to the carrier 33; the pressing block 42 is movably arranged on the fixed frame 41 and abuts against the inner top wall of the accommodating cavity 20 to provide damping; the elastic member 43 is installed on the fixed frame 41 and abuts against the pressing block 42, and the elastic member 43 can be deformed as the pressing block 42 shakes.
[0050] Specifically, under normal circumstances, the elastic member 43 provides support for the pressing block 42, enabling the pressing block 42 to fit against the inner top wall of the receiving cavity 20. The elastic potential energy of the elastic member 43 is relied upon to provide damping, thereby further enhancing the rotational stability of the carrier base 33. Meanwhile, when the carrier base 33 is impacted by an external force, the carrier base 33 transmits the impact force to the pressing block 42, causing the pressing block 42 to slightly shake. The elastic member 43 can deform as the pressing block 42 shakes, thereby mitigating the impact of the impact force on the carrier base 33. After the impact is completed, the elastic member 43 returns to its original state and causes the pressing block 42 to fit against the inner top wall of the receiving cavity 20 again.
[0051] Therefore, the design of the buffer portion 4 can, on the one hand, increase the damping force between the carrier base 33 and the base shell 2, preventing the mirror body 1 from swinging randomly and affecting driving safety. On the other hand, it can mitigate the impact force when the mirror body 1 collides, reducing the likelihood of damage to the carrier base 33 and the rotating rod 331.
[0052] It should be noted that the deformation and recovery of the elastic member 43 are completed instantaneously, and the impact force instantaneously applied to the carrier base 33 is also mitigated by it. Therefore, buffering can be carried out before the rotating rod 331 is damaged.
[0053] Refer to the appendix Figure 13 - appendix Figure 14 . There are various types of elastic members 43. For example, a spring [not shown in the figure] or a rubber column [not shown in the figure] can be used. In order to reduce the volume of the fixing frame 41, in this embodiment, the elastic member 43 is a spring wire 430. The fixing frame 41 is provided with a placement opening 410, and two insertion holes 4100 are connected on both sides of the placement opening 410. The pressing block 42 is movably arranged at the placement opening 410. The spring wire 430 is placed in the placement opening 410 and inserted into the two insertion holes 4100, and the spring wire 430 abuts against the pressing block 42. The spring wire 430 can deform as the pressing block 42 shakes.
[0054] Specifically, when the carrier base 33 is impacted, the pressing block 42 moves within the placement opening 410 and applies a pressure to the spring wire 430, causing the spring wire 430 to deform to absorb the impact force. When there is no external force on the carrier base 33, the spring wire 430 releases energy and returns to its initial state, causing the pressing block 42 to remain in contact with the inner top wall of the receiving cavity 20.
[0055] Among them, the combined use of the placement opening 410 and the two insertion holes 4100 facilitates the installation and disassembly of the pressing block 42 and the spring wire 430, improving the assembly convenience.
[0056] Refer to the appendix Figure 13 - appendix Figure 14 . The pressing block 42 is designed in a wheel shape, and a wheel groove 420 is provided in the circumferential direction of the pressing block 42. The wheel groove 420 is in sliding fit with the spring wire 430.
[0057] Among them, the pressing block 42 is designed in a wheel shape, which can reduce the friction between the pressing block 42 and the inner top wall of the receiving cavity 20, extend the service life of the pressing block 42, and when the carrier 33 rotates, the pressing block 42 with a wheel shape design can rotate accordingly, playing a certain auxiliary role; the design of the wheel groove 420 can increase the contact area with the spring wire 430, prevent the spring wire 430 from falling off, and ensure that the pressing block 42 remains in contact with the elastic wire when rotating.
[0058] Refer to the appendix Figure 13 - appendix Figure 14 , there are multiple placement openings 410, which are arranged in a circumferential array on the fixed frame 41. There are multiple pressing blocks 42 and spring wires 430, corresponding to the multiple placement openings 410 one by one; this design makes the forces on each side of the carrier 33 uniform, further improving the rotational stability of the carrier 33 and reducing the possibility of damage to the rotating rod 331.
[0059] Refer to the appendix Figure 3 - appendix Figure 4 and appendix Figure 8 - appendix Figure 12 , the types of the driving member 31 are diverse, and the present utility model does not limit this. For the convenience of understanding, in this embodiment, the driving member 31 includes a servo motor 311 and a worm 312. There are multiple teeth 320 arranged in a circumferential array on the outer wall of the linkage head 32. The linkage head 32 is meshed and connected with the worm 312 through the teeth 320; the servo motor 311 is drivingly connected to the worm 312 to drive the linkage head 32 to rotate through the worm 312.
[0060] Specifically, when in use, the servo motor 311 is started to control the forward or reverse rotation of the worm 312. Under the cooperation of the worm 312 and the teeth 320, the linkage head 32 will also rotate forward or reverse, thereby adjusting the rotation angle of the mirror body 1 installed on the carrier 33.
[0061] It should be noted that the servo motor 311 runs along the base shell 2 and the vehicle body wiring and is finally electrically connected to the vehicle console to control the operating state of the servo motor 311 through the console. The related technology belongs to the prior art, so the present utility model does not elaborate on its circuit structure in detail.
[0062] Refer to the appendix Figure 3 - appendix Figure 11 , the present utility model further includes a limiting portion 5. The limiting portion 5 includes a limiting cylinder 51 and a collar 52. The bottom of the receiving cavity 20 is connected to a shaft cavity 200. The bottom end of the linkage head 32 is provided with a sleeve cavity 322 coaxially designed with the rotating hole 321; the limiting cylinder 51 is coaxially arranged in the shaft cavity 200, and the top end of the limiting cylinder 51 extends into the receiving cavity 20; the collar 52 is installed in the sleeve cavity 322 and sleeved on the top end of the limiting cylinder 51; the top and bottom ends of the linkage head 32 respectively abut against the carrier 33 and the limiting cylinder 51.
[0063] The use of the limiting cylinder 51 and the collar 52 can coaxially limit the linkage head 32 and the rotating rod 331 on the axis of the shaft cavity 200, thereby preventing the carrier 33 from deviating on the horizontal plane during rotation; and the top and bottom ends of the linkage head 32 respectively abut the carrier 33 and the limiting cylinder 51, thereby limiting the movement of the linkage head 32 along the axis of the shaft cavity 200, thereby preventing the carrier 33 from deviating on the vertical plane during rotation; therefore, the design of the limiting part 5 further improves the installation stability of the carrier 33.
[0064] See attached Figure 7 -Attached Figure 11 , an inner cavity 511 is provided at the axis of the limiting cylinder 51, and a plurality of notches 512 connected to the inner cavity 511 are arranged in a circumferential array on the top of the limiting cylinder 51, and wheel posts 513 are movably arranged in the plurality of notches 512; a plurality of bayonet holes 521 are arranged in a circumferential array on the inner wall of the sleeve 52, and when the sleeve 52 is sleeved on the top of the limiting cylinder 51, it synchronously abuts against the outer sides of the plurality of wheel posts 513, and the plurality of bayonet holes 521 are adapted to the plurality of wheel posts 513 one by one; the sleeve cavity 322 is connected to the rotating hole 321, and the rotating rod 331 rotatably passes through the sleeve cavity 322 and extends to the inner cavity 511 of the limiting cylinder 51, so as to synchronously abut against the inner sides of the plurality of wheel posts 513.
[0065] Among them, since the rotating rod 331 and the collar 52 respectively abut against the inner and outer sides of the plurality of wheel posts 513, the plurality of wheel posts 513 can be clamped inside to prevent the wheel posts 513 from falling off; and when the mirror body 1 is manually adjusted, the plurality of wheel posts 513 continuously fall off and engage with the plurality of bayonet ports 521 to produce a sound, thereby providing the operator with corresponding information feedback and improving the operating feel.
[0066] See attached Figure 4 -Attached Figure 8 , the utility model also includes a bearing 6, a rotating cavity 3310 with a downward opening is provided at the bottom of the rotating rod 331, and a vertical rod 201 is coaxially installed in the axial cavity 200; the bearing 6 is installed on the vertical rod 201, and the rotating rod 331 is sleeved with the bearing 6 through the rotating cavity 3310; the bearing 6 can provide support for the rotating rod 331 and facilitate the rotation of the rotating rod 331, so as to further improve the rotation stability of the carrier 33.
[0067] See attached Figure 4 -Attached Figure 10 A rubber sleeve 332 is installed on the outer wall of the rotating rod 331, and the rotating rod 331 is interference-fitted with the rotating hole 321 through the rubber sleeve 332.
[0068] Among them, since the rubber sleeve 332 is used, when the damping between the rotating rod 331 and the rotating hole 321 is reduced, the rubber sleeve 332 can be directly replaced to reduce maintenance costs; in addition, the rubber sleeve 332 can be made of rubber material to improve wear resistance, and the rubber sleeve 332 can also be directly bonded and fixed to the rotating rod 331 using glue, which is easy to install.
[0069] It should also be noted that, although the embodiments of the present application have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application.
