[0029] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] An embodiment of the utility model provides a rearview mirror adjustment structure, including a trigger component and a drive component; the trigger component is triggered under set conditions to control the start and stop of the drive component, and after the drive component is running, the angle of the lens can be adjusted so that in this application scenario, the angle of the lens meets the usage requirements.

[0031] The following is a detailed description of the structures of the components of the rearview mirror adjustment structure provided by the embodiment of the utility model, as well as the connection relationship and position relationship of the components, in conjunction with the accompanying drawings.

[0032] like Figures 1 to 4 As shown, the trigger component 10 is connected to the drive component 20 and is used to control the start and stop of the drive component 20; the start of the drive component 20 needs to be under specific conditions. For example, in the embodiment of the utility model, the start condition of the drive component 20 is that the vehicle turns right, so it is necessary to start the drive component 20 through the trigger component 10 when or before the right turn occurs. How to trigger the trigger component 10 is described below.

[0033] In the embodiment of the utility model, the driving assembly 20 includes a pushing member 21 and a resetting member 22. The pushing member 21 is used to push the lens 30 of the rearview mirror to rotate to a set angle, from the original position to the expanded field of view position, and the resetting member 22 is used to push the lens 30 to reset, from the expanded field of view position to the original position.

[0034] As described above, the driving assembly 20 is started under the set condition, that is, it can be understood that when the vehicle is in the set state, the lens 30 needs to be rotated to the expanded field of view position, and after the set condition is eliminated, the lens 30 needs to be reset to the original position. In the embodiment of the utility model, the lens 30 is controlled to rotate to the expanded field of view position by the pusher 21, and the lens 30 is reset to the original position by the reset member 22.

[0035] For example, the pusher 21 is located on the back side of the lens 30; the pusher 21 includes a motor 211 and a rotating blade 212, the axis of the output shaft of the motor 211 is parallel to the lens 30, the rotating blade 212 is connected to the output shaft of the motor 211, and the rotating blade 212 rotates synchronously with the output shaft of the motor 211 to abut and push the lens 30 to rotate.

[0036] When the motor 211 is not rotating, the rotating blade 212 does not contact the back side of the lens 30. As the motor 211 rotates, the rotating blade 212 rotates synchronously with the output shaft of the motor 211. The rotating blade 212 first contacts the back side of the lens 30. Then, under the force of the rotating blade 212, the lens 30 is pushed to rotate a certain angle, that is, to reach the expanded field of view position. For example, the pusher 21 is used to push the lens 30 of the rearview mirror to rotate a set angle, and the set angle range is 15 degrees to 60 degrees.

[0037] Taking the right turn of the vehicle as an example, the rearview mirror structure is applied to the rearview mirror on the right side of the vehicle. If the lens 30 of the rearview mirror always maintains the original position, as the vehicle turns right, the field of view that the driver can observe through the right rearview mirror becomes smaller. By properly rotating the lens 30 of the rearview mirror "outward", that is, rotating the end of the lens 30 away from the vehicle in the direction away from the vehicle, the field of view observed by the driver through the rearview mirror can be increased, thereby achieving the effect of assisting right turns.

[0038] For example, the reset member 22 is located on the back side of the lens 30; the reset member 22 is an elastic structure 221, and the elastic expansion and contraction direction of the elastic structure 221 is perpendicular to the lens 30. When the lens 30 rotates from the original position to the expanded field of view position, the lens 30 gradually presses the elastic structure 221 to shrink the elastic structure 221. When the expanded field of view position is rotated to the original position, the motor 211 stops rotating, and the elastic structure 221 drives the lens 30 to rotate and reset.

[0039] Similarly, in the initial state, the end of the elastic structure 221 is spaced a certain distance from the back side of the lens 30. As the lens 30 rotates, the back side of the lens 30 gradually approaches the end of the elastic structure 221 and gradually applies pressure to the elastic structure 221, causing the elastic structure 221 to shrink axially.

[0040] After the lens 30 rotates to the specified position, the force of the output shaft of the motor 211 counteracts the elastic force output by the elastic structure 221 to the lens 30, so that the lens 30 remains in the current position (i.e., the position of expanding the field of view). After the right turn is completed, the force of the output shaft of the motor 211 disappears, and the rebound force of the elastic structure 221 drives the lens 30 to rotate in the opposite direction, and finally resets the lens 30. Among them, the timing when the force of the output shaft of the motor 211 disappears (the motor 211 stops running) is also based on the signal applied by the trigger component 10, and the specific operation method is described below.

[0041] For example, the rearview mirror adjustment structure also includes a frame 40, the frame 40 includes a receiving groove 41, the lens 30 is arranged at the notch of the receiving groove 41, the trigger assembly 10 and the driving assembly 20 are arranged in the receiving groove 41; the elastic structure 221 is a contraction spring, one end of the contraction spring is connected to the frame 40, and the other end is used to abut against the back side of the lens 30.

[0042] Continue to refer Figures 1 to 4 As shown, in the embodiment of the utility model, the trigger component 10 includes a trigger switch 11 and an inertial trigger structure 12; the trigger switch 11 is connected to the motor 211 and is used to control the start and stop of the motor 211; the inertial trigger structure 12 moves along a set path under the inertia of the vehicle, and the trigger switch 11 is located on the path. When the inertial trigger structure 12 moves, it touches the trigger switch 11 to turn on.

[0043] The switch operation of the trigger switch 11 realizes the start and stop control of the motor 211. In the embodiment of the utility model, the inertial trigger structure 12 starts the trigger switch 11 under the inertia of the vehicle. For example, when the vehicle turns right, the vehicle will be subjected to the inertial force in the left direction. The inertial force is used to start the trigger switch 11, which can ensure the accuracy of the trigger switch 11. Specifically:

[0044] In the embodiment of the utility model, the inertial trigger structure 12 includes a slope slide rail 121 and a trigger slider 122; the height between the first end of the slope slide rail 121 and the bottom of the lens 30 is greater than the height between the second end and the bottom of the lens 30, the trigger switch 11 is located at the first end of the slope slide rail 121, and the trigger slider 122 is located at the second end of the slope slide rail 121; under the action of vehicle inertia, the trigger slider 122 slides from the second end of the slope slide rail 121 to the first end, and touches the trigger switch 11 to turn on.

[0045] When the vehicle is in normal driving state, the trigger slider 122 is located at the second end, or at a position between the first end and the second end where the trigger switch 11 is not triggered. As the vehicle turns right, the vehicle as a whole generates an inertial force to the left. At this time, the trigger slider 122 gradually moves from the second end to the first end, and finally touches the trigger switch 11. The trigger switch 11 is turned on, the motor 211 starts to run, and the lens 30 is moved to the expanded viewing angle position. As the right turn progresses, the trigger slider 122 keeps the trigger switch 11 turned on; when the right turn is completed, the inertial force to the left gradually disappears, the trigger slider 122 gradually moves from the first end to the second end, the trigger switch 11 is turned off, the motor 211 stops running, and under the action of the elastic structure 221, the lens 30 is reset to its original position.

[0046] For example, in an embodiment of the present invention, the method for controlling the rotation angle of the lens 30 is as follows: after the trigger switch 11 is turned on for a period of time, the output shaft of the motor 211 stops rotating, and the force of the output shaft of the motor 211 is kept equal to the rebound force of the elastic structure 221 until the trigger switch 11 is turned off. This design method can avoid the excessive rotation angle of the lens 30 caused by the continuous rotation of the output shaft of the motor 211 when the trigger switch 11 is turned on.

[0047] Continue to refer Figures 1 to 4As shown, in the embodiment of the utility model, the slope slide rail 121 includes a slide groove 1211 arranged along the direction from the first end to the second end, the trigger slider 122 is arranged in the slide groove 1211, and a groove cover 1212 is provided on the groove of the slide groove 1211; the trigger slider 122 slides in the space enclosed by the slide groove 1211 and the groove cover 1212.

[0048] The slope slide rail 121 is set as a groove structure, which can limit the trigger slider 122 in other directions to prevent the trigger slider 122 from falling off or being triggered by mistake in other driving scenarios, such as going uphill, downhill, braking or reversing.

[0049] For example, in the embodiment of the present invention, the trigger switch 11 and the first end of the slope rail 121 are disposed on the side wall of the receiving groove 41. For example, the side wall is the side wall of the receiving groove 41 close to the left side, and when the rearview mirror is connected to the vehicle, this end is also connected to the vehicle, so the wiring harness connected to the trigger switch 11 can pass through the side wall and be connected to the internal controller of the vehicle.

[0050] In the embodiment of the utility model, other methods can be used to trigger the trigger switch 11. For example, when the steering wheel is operated to the right, such as when the steering wheel is rotated to a certain angle, the trigger switch 11 is triggered; or, for example, when the driver turns the right turn lever, the trigger switch 11 is triggered.

[0051] The embodiment of the utility model also provides a rearview mirror, including the above rearview mirror adjustment structure. The rearview mirror is a rearview mirror on the right side of the vehicle. When the vehicle turns right, the lens 30 of the rearview mirror rotates from the original position to the expanded field of view position, such as Figure 6 As shown, at this time, the driver can obtain a wider field of view through the rearview mirror; when the right turn operation is completed, the lens 30 of the rearview mirror is reset to the original position and can be used normally, such as Figure 5 The position of the lens 30 is shown.

[0052] The utility model provides a rearview mirror adjustment structure and a rearview mirror, wherein a driving component 20 can control the lens 30 of the rearview mirror to rotate from an original position to an expanded field of view position, wherein the start and stop of the driving component 20 is controlled by a trigger component 10, and when the vehicle turns right, the trigger component 10 starts the driving component 20, and after the lens 30 rotates to the expanded field of view position, the driver can observe the right side road conditions with a larger viewing angle through the lens 30 of the rearview mirror, thereby assisting the driver's steering operation. The technical solution of the utility model avoids the problem that the driver relies on experience to slow down and turn, or tilts his head to make subjective judgments and ignores the safety hazards of the front and left sides, and has higher safety.
