Description

Technical Field

[0001] This utility model relates to the field of automotive rearview mirror technology, and in particular to an anti-glare interior rearview mirror. Background Technology

[0002] The rearview mirror in the driver's cab is mainly used to observe the situation behind the vehicle through the rear windshield. When the vehicle behind turns on its high beams, the rearview mirror will reflect strong light into the driver's eyes, causing glare for a few seconds, which seriously affects driving safety. Therefore, the rearview mirror needs to be designed to prevent glare. The manual anti-glare rearview mirror is switched between anti-glare mode and normal mode by moving a lever, which causes the adjustment seat in the mirror frame and the wedge-shaped lens to rotate.

[0003] In the existing technology, because the adjustment seat and the lever are connected by a snap-fit, the driver's feel is not good when turning it. The damping is directly reflected to the hand through the lever. Moreover, when driving at night, it is sometimes necessary to repeatedly turn the lever to switch the mode of the interior rearview mirror, which further reduces the driver's operating experience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-glare rearview mirror, which aims to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An anti-glare rearview mirror includes a mirror frame, an adjustment seat rotatably disposed in the mirror frame, a wedge-shaped lens connected to the adjustment seat, a connecting assembly movably connecting the adjustment seat and the vehicle body, and a toggle assembly rotatably disposed in the mirror frame. The toggle assembly includes a first connecting handle rotatably connected to the mirror frame, a contact block disposed at one end of the first connecting handle near the adjustment seat, a second connecting handle rotatably connected to the mirror frame, and a third connecting handle rotatably connected at both ends to the first connecting handle and the second connecting handle. The mirror frame is provided with a clearance hole for the second connecting handle to move through, and the contact block is engaged with the bottom end of the adjustment seat.

[0007] According to one aspect of the above technical solution, the middle part of the first connecting handle is provided with a rotatable connection to the mirror frame via a first rotating shaft.

[0008] According to one aspect of the above technical solution, the middle part of the second connecting handle is rotatably connected to the frame via a second pivot.

[0009] According to one aspect of the above technical solution, the adjustment seat is rotatably connected to the mirror frame via a third rotating shaft.

[0010] According to one aspect of the above technical solution, the connecting component includes a support rod connected to the vehicle body and a ball joint disposed at the free end of the support rod.

[0011] According to one aspect of the above technical solution, the middle part of the adjusting seat is provided with a fixing hole for connection with the ball head, the wedge-shaped lens is fixed to the side of the adjusting seat away from the support rod, and the thickness of the upper part of the wedge-shaped lens is greater than the thickness of the lower part.

[0012] According to one aspect of the above technical solution, a fourth rotating shaft is provided at one end of the first connecting handle near the second connecting handle, a fifth rotating shaft is provided at one end of the second connecting handle near the first connecting handle, and the two ends of the third connecting handle are respectively rotatably mounted on the fourth rotating shaft and the fifth rotating shaft.

[0013] According to one aspect of the above technical solution, the end of the second connecting handle away from the first connecting handle is provided with an anti-slip sleeve.

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

[0015] By setting a first connecting handle and a second connecting handle that are rotatably connected to the frame, and setting a third connecting handle that is rotatably mounted on the first and second connecting handles, when it is necessary to switch the angle of the wedge lens to achieve the anti-glare function, the second connecting handle is turned so that the third connecting handle drives the first connecting handle to rotate. This causes the contact block at the end of the first connecting handle to drive the adjustment seat to rotate slightly until the contact block engages with the bottom end of the adjustment seat, thus fixing the wedge lens. This design structure makes the feel of turning the handle better, because the first connecting handle is rotated by the second connecting handle, and the third connecting handle is in the middle. Therefore, the finger can be placed on the second connecting handle to reduce the feeling of jamming, and it is more effortless and improves the operation. Attached Figure Description

[0021] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0022] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] 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 herein 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.

[0025] Please see Figures 1 to 3 The image shows an anti-glare rearview mirror according to the first embodiment of the present invention, including a mirror frame 10, an adjustment seat 30 rotatably disposed in the mirror frame 10, a wedge-shaped lens 20 connected to the adjustment seat 30, a connecting assembly movably connecting the adjustment seat 30 and the vehicle body, and a toggle assembly rotatably disposed in the mirror frame 10. The toggle assembly includes a first connecting handle 51 rotatably connected to the mirror frame 10, a contact block 57 disposed at one end of the first connecting handle 51 near the adjustment seat 30, a second connecting handle 58 rotatably connected to the mirror frame 10, and a third connecting handle 54 rotatably connected at both ends to the first connecting handle 51 and the second connecting handle 58. The mirror frame 10 is provided with a clearance hole 60 for the second connecting handle 58 to move through it, and the contact block 57 is engaged with the bottom end of the adjustment seat 30.

[0026] Understandably, the wedge-shaped lens 20 is attached to the attachment surface 33 of the adjustment seat 30. By providing a first connecting handle 51 and a second connecting handle 58 rotatably connected to the frame 10, and a third connecting handle 54 rotatably mounted on the first and second connecting handles 51 and 58, when the angle of the wedge-shaped lens 20 needs to be switched to achieve the anti-glare function, the second connecting handle 58 is moved, causing the third connecting handle 54 to rotate the first connecting handle 51. This, in turn, causes the contact block 57 at the end of the first connecting handle 51 to rotate the adjustment seat 30 slightly until the contact block 57 engages with the bottom end of the adjustment seat 30, thus fixing the wedge-shaped lens 20. The design structure improves the feel of the toggle, because the first connecting handle 51 is rotated by the second connecting handle 58, and a third connecting handle 54 is provided in the middle. Therefore, the finger can reduce the feeling of jamming when it is placed on the second connecting handle 58, and it is more effortless and improves the operation. In some embodiments, by reasonably adjusting the rotation stroke of each component, the overall toggle assembly can be extended, making it easier for the driver to find the toggle assembly while driving. (It should be noted that in this embodiment, the overall length of the toggle assembly is not extended, but the length of the first connecting handle 51 is reduced, and the length of the second connecting handle 58 extending out of the mirror frame 10 is the same as the length of the existing toggle assembly extending out of the mirror frame 10.)

[0027] Furthermore, the middle part of the first connecting handle 51 is rotatably connected to the frame 10 via the first pivot 52, and the middle part of the second connecting handle 58 is rotatably connected to the frame 10 via the second pivot 56.

[0028] Understandably, since we use the second connecting handle 58 to drive the first connecting handle 51 to rotate, and the rotation distance of the second connecting handle 58 is nearly twice the rotation distance of the first connecting handle 51, we need to change the original setting of the first rotating shaft 52 at the end of the first connecting handle 51 near the adjusting seat 30. Instead, we need to move the first rotating shaft 52 slightly backward so that the rotation distance of the first connecting handle 51 is smaller, while the stroke of the end of the first connecting handle 51 near the adjusting seat 30 remains roughly the same, accommodating the engagement between the contact block 57 and the bottom of the adjusting seat 30. This achieves the goals of saving effort and improving the feel of the handle without significantly altering the original structure.

[0029] Furthermore, the adjustment seat 30 is rotatably connected to the mirror frame 10 via a third rotating shaft 35.

[0030] Understandably, since the first connecting handle 51 and the lever drive the bottom of the adjusting seat 30 to rotate, the top of the adjusting seat 30 will have a slight displacement of about 3° to 5° around the third rotating shaft 35, which in turn will cause the lens to rotate by 3° to 5°.

[0031] It should be noted that since this application only changes the structure of the toggle assembly, the snap-fit ​​principle between the bottom of the adjustment seat 30 and the contact block 57 is similar to that of the existing ones, and will not be described in detail here. In short, when the contact block 57 rotates, the protrusion 571 on it will contact the protrusion 32 on the adjustment seat 30 to drive the adjustment seat 30 to rotate. At this time, the buckle 3131 on the adjustment seat 30 will cooperate with the slot 572 on the contact block 57 until the adjustment seat 30 rotates to the point where the buckle 3131 and the slot 572 are engaged, thereby realizing the rotation of the wedge lens 20.

[0032] Furthermore, the connecting assembly includes a support rod 40 connected to the vehicle body and a ball head 41 located at the free end of the support rod 40; the middle of the adjusting seat 30 is provided with a fixing hole 34 connected to the ball head 41; the wedge-shaped lens 20 is fixed to the side of the adjusting seat 30 away from the support rod 40; and the thickness of the upper part of the wedge-shaped lens 20 is greater than the thickness of the lower part.

[0033] Understandably, when installing the interior rearview mirror, the ball joint 41 is movably connected to the fixing hole 34 of the adjustment seat 30. Although the mirror frame 10 and the adjustment seat 30 have a rotational relationship through the third rotating shaft 35, the mirror frame 10 is also fixed by the friction of the ball joint 41 because the mirror frame 10 and the adjustment seat 30 are very close together. This prevents the mirror frame 10 and the adjustment seat 30 from being too loose. Only when the adjustment seat 30 and the wedge lens 20 are rotated by the toggle assembly can the adjustment seat 30 rotate slightly relative to the mirror frame 10.

[0034] Furthermore, the first connecting handle 51 is provided with a fourth rotating shaft 53 at one end near the second connecting handle 58, the second connecting handle 58 is provided with a fifth rotating shaft 55 at one end near the first connecting handle 51, and the two ends of the third connecting handle 54 are respectively rotatably mounted on the fourth rotating shaft 53 and the fifth rotating shaft 55; the second connecting handle 58 is provided with an anti-slip sleeve 581 at one end away from the first connecting handle 51.

[0035] Understandably, by setting the fourth pivot 53 and the fifth pivot 55, the third connecting handle 54 can be rotatably positioned between the first connecting handle 51 and the second connecting handle 58. The anti-slip sleeve 581 can facilitate the driver to move the second connecting handle 58, avoiding slippage that could prevent the second connecting handle 58 from moving and thus causing a traffic accident.

[0036] The principles of the remaining unexplained aspects are consistent with those of the existing manual anti-glare rearview mirror, and will not be elaborated upon here.

[0037] In summary, the anti-glare rearview mirror in the above embodiments of this utility model provides a better feel when toggling, because the first connecting handle is rotated by the second connecting handle, and a third connecting handle is provided in the middle. Therefore, the finger can reduce the feeling of jamming when it is placed on the second connecting handle. At the same time, the overall length of the toggle component is extended, making it easier for the driver to find the toggle component while driving.
