Description

Technical Field

[0001] This application relates to the field of automotive rearview mirror technology, and in particular to a retractable rearview mirror mechanism. Background Technology

[0002] As a key component ensuring driving safety, the functionality and ease of use of automotive exterior rearview mirrors directly impact the driving experience and road safety. With the automotive industry's increasing demands for space adaptability, exterior design, and safety, electrically folding rearview mirrors have gradually become a mainstream feature, widely used in scenarios such as navigating narrow spaces, automatic car washing, and preventing scratches.

[0003] In related technologies, the core principle of currently available electric folding rearview mirrors is to drive the entire rearview mirror assembly (including the housing and lens) to rotate around a fixed axis by a certain angle, usually 70°-90°, so that the rearview mirror assembly fits tightly against the side of the vehicle body, thereby reducing the space occupied.

[0004] In actual use, it has been found that even when the existing rearview mirrors are folded, the rearview mirror assembly still protrudes from the side of the vehicle body. This not only destroys the overall streamlined design aesthetics of the vehicle body and reduces the harmony of the vehicle's appearance, but also makes it impossible to further optimize the drag coefficient, which is not conducive to improving the vehicle's energy consumption performance. Utility Model Content

[0005] To improve the concealment function of rearview mirrors, this application provides a concealable rearview mirror mechanism, which enhances the concealment function of rearview mirrors, improves the overall streamlined design aesthetics of the vehicle body, and optimizes the overall drag coefficient of the vehicle body.

[0006] The retractable rearview mirror mechanism provided in this application adopts the following technical solution: A retractable rearview mirror mechanism includes a bracket and a rearview mirror. A movable frame is slidably mounted on the bracket. A translation component is mounted on the movable frame. The translation component is used to drive the movable frame to move along the height direction of the bracket. A rotary drive is mounted on the movable frame. A rotating shaft is mounted on the output shaft of the rotary drive. The rotary drive is used to drive the rotating shaft to rotate. The rearview mirror is fixed to the end of the rotating shaft away from the rotary drive.

[0007] By adopting the above technical solution, when it is necessary to hide the rearview mirror, the rotating drive component first drives the rotating shaft to rotate. The rotating shaft drives the rearview mirror to rotate until it is parallel to the vehicle body, and then the rotating drive component stops. Subsequently, the translation component drives the moving frame to move down along the bracket, so that the entire rearview mirror is folded and hidden to the side of the vehicle body hood. This effectively improves the hiding function of the rearview mirror, enhances the overall streamlined design aesthetics of the vehicle body, and optimizes the overall drag coefficient of the vehicle body.

[0008] Optionally, the translation component includes a translation drive, a gear, and a rack meshing with the gear. The translation drive is mounted on the moving frame, and the output shaft of the translation drive is fixed to the gear. The rack is located between the support and the moving frame and is fixed to the support. The translation drive drives the gear and rack to mesh and transmit power.

[0009] By adopting the above technical solution, when the moving frame needs to be driven downward, the translation drive is activated. The output shaft of the translation drive drives the gear and rack to mesh and transmit power. The moving frame moves the rearview mirror along the slide rail with the slider until the rearview mirror is in contact with the side of the vehicle hood, thus completing the concealment of the rearview mirror. The meshing transmission of the gear and rack is converted into the linear motion of the moving frame. Furthermore, through the sliding cooperation between the slider and the slide rail, the slider supports the moving frame, effectively improving the stability of the moving frame.

[0010] Optionally, a fixed frame is provided at the end of the movable frame away from the translation drive component, the rotation drive component is located on the side of the fixed frame close to the translation drive component, a support base is provided on the fixed frame, the rotation shaft is rotatably connected to the support base, and the rotation shaft is parallel to the length direction of the fixed frame.

[0011] By adopting the above technical solution, the support seat provides radial support for the rotation of the rotating shaft, effectively reducing the rotational sway of the rotating shaft caused by gravity, thereby improving the rotational stability of the rotating shaft.

[0012] Optionally, a first rotary switch and a second rotary switch are provided on the side of the fixed frame near the rotating shaft. The first rotary switch and the second rotary switch are arranged at an angle. A connecting sleeve is provided on the output shaft of the rotary drive. The end of the connecting sleeve away from the rotary drive is fixed to the rotating shaft. A pressing element that contacts the first rotary switch or the second rotary switch is provided on the connecting sleeve.

[0013] By adopting the above technical solution, when the pressing part touches the first rotary switch or the second rotary switch, the rotating shaft drives the rearview mirror to rotate to the unfolded or retracted angle. The rotary switch box rotary drive component sends a stop signal, reducing the damage to the components caused by the continuous rotation of the rotary drive component, effectively reducing the risk of operational errors, and improving the safety of the rearview mirror operation.

[0014] Optionally, the bracket is provided with a slide rail, which is parallel to the rack, and the bottom of the movable frame is provided with a slider, which slides in cooperation with the slide rail.

[0015] By adopting the above technical solution, when the translation drive component drives the moving frame to move, the slider moves linearly along the slide rail. The slide rail provides guidance for the vertical movement of the moving frame, reducing the tilting or jamming of the moving frame under gravity, which helps to improve the stability of the moving frame.

[0016] Optionally, the bracket is provided with a downward limit switch, which is located between the slide rail and the rack. The downward limit switch is located at the end of the slide rail, and a connecting rod is provided on the side of the slider near the rack. When the slider slides to the end of the slide rail, the connecting rod touches the downward limit switch.

[0017] By adopting the above technical solution, when the moving frame moves down to the point where the connecting rod touches the downward limit switch, the translation drive component self-locks, ensuring that the rearview mirror moves down to the designated position and remains stably in that position. This reduces the damage to components caused by the continuous downward movement of the rearview mirror and helps extend the service life of components such as the rearview mirror.

[0018] Optionally, the bracket is provided with an upward limit switch, which is located between the slide rail and the rack. The downward limit switch is located at the end of the slide rail away from the upward limit switch. The upward limit switch and the downward limit switch are arranged opposite to each other. When the slider slides to the end of the slide rail away from the downward limit switch, the connecting rod touches the upward limit switch.

[0019] By adopting the above technical solution, when the moving frame moves upward to the point where the connecting rod touches the upward limit switch, the translation drive stops, causing the moving frame to stop rising. This reduces the occurrence of the moving frame detaching from the support and ensures that the entire sliding groove of the moving frame is always within a safe range, which is beneficial for protecting the rearview mirror mechanism.

[0020] Optionally, the rearview mirror is detachably provided with a mounting bracket, which is fixed to the end of the rotating shaft away from the rotating drive component.

[0021] By adopting the above technical solution, the rearview mirror and the rotating shaft mounting bracket are detachably connected, which facilitates the removal and replacement of the rearview mirror and reduces maintenance costs.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When the rearview mirror needs to be hidden, the rotating drive component first drives the rotating shaft to rotate. The rotating shaft drives the rearview mirror to rotate until it is parallel to the vehicle body, and then the rotating drive component stops. Subsequently, the translation component drives the moving frame to move down along the bracket, so that the entire rearview mirror is folded and hidden to the side of the vehicle body hood. This effectively improves the hiding function of the rearview mirror, enhances the overall streamlined design aesthetics of the vehicle body, and optimizes the overall drag coefficient of the vehicle body. 2. The structure is compact and requires no modification to the vehicle body. Furthermore, the rearview mirror mechanism is integrated inside the rearview mirror assembly, which requires far less modification to the vehicle body than the traditional recessed hiding solution, effectively improving the applicability of the structure. 3. By adopting a motor and gear / rack drive system, the rearview mirror has a limit switch and motor self-locking function after it moves to the position, which can ensure that the position of the rearview mirror remains stable in the unfolded or folded hidden state and will not loosen due to vibration or airflow. It has high stability. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0026] This application discloses a retractable rearview mirror mechanism, referring to... Figure 1 and Figure 2 The device includes a bracket 1 and a rearview mirror 2. A movable frame 3 is slidably mounted on the bracket 1 and slides along the height direction of the bracket 1. A translation component 4 is provided on one side of the movable frame 3 and is used to drive the movable frame 3 to move. A rotary drive component 5 is installed on the side of the movable frame 3 near the translation component 4. In this embodiment, the rotary drive component 5 is a motor. A rotating shaft 6 is fixed on the output shaft of the rotary drive component 5. The rotating shaft 6 is located on the side of the movable frame 3 away from the bracket 1. The rearview mirror 2 is fixed to the end of the rotating shaft 6 away from the rotary drive component 5. The rotary drive component 5 drives the rotating shaft 6 and the rearview mirror 2 to rotate synchronously.

[0027] The rearview mirror 2 is installed on the A-pillar and hood hinge of the car. A rotary drive component 5 drives the rearview mirror 2 to rotate, and a translation component 4 drives the rearview mirror 2 to move linearly. This allows the rearview mirror 2 shell to be completely integrated into the side of the hood after folding, effectively enhancing the vehicle's overall appearance and technological feel, while further reducing wind resistance. Figure 1 Show the unfolded state of rearview mirror 2.

[0028] Reference Figure 1 and Figure 2The translation component 4 includes a translation drive 41, a gear 42, and a rack 43. In this embodiment, the translation drive 41 is a motor. The translation drive 41 is fixed to the side of the moving frame 3 away from the support 1 by bolts. The output shaft of the translation drive 41 passes through the moving frame 3 and is fixed to the gear 42 by bolts. The rack 43 is fixed to one side of the support 1 by bolts and is located between the support 1 and the moving frame 3. The translation drive 41 drives the rack 43 to mesh with the gear 42 for transmission.

[0029] When the translation drive 41 is activated, it drives the gear 42 to rotate, and then the gear 42 meshes with the rack 43 to transmit power, so that the moving frame 3 moves linearly on the bracket 1, and then the rearview mirror 2 housing can be completely integrated into the side of the vehicle body hood after folding, effectively improving the hiding effect of the rearview mirror 2.

[0030] Reference Figure 1 and Figure 2 The bracket 1 is fixed with a slide rail 13 by bolts. In this embodiment, there are two slide rails 13, which are spaced apart and parallel to the rack 43. The bottom of the movable frame 3 is fixed with a slider 14 by bolts. There are two sliders 14, which slide in cooperation with the two slide rails 13 respectively. The two ends of the bracket 1 are fixed with an upward limit switch 17 and a downward limit switch 15 by bolts. The upward limit switch 17 and the downward limit switch 15 are arranged opposite to each other and are both located between the slide rail 13 and the rack 43.

[0031] Reference Figure 2 A connecting block 19 is fixed to the slider 14 by bolts. The connecting block 19 is located between the slider 14 and the moving frame 3. A connecting rod 16 is integrally formed on the connecting block 19 near the rack 43. The connecting rod 16 is located between the upper limit switch 17 and the lower limit switch 15. When the slider 14 slides to the end of the slide rail 13, the connecting rod 16 presses the lower limit switch 15 or the upper limit switch 17, so that the translation drive 41 self-locks, ensuring that the rearview mirror 2 can stably maintain the position after it has been translated to the designated position.

[0032] Reference Figure 1 and Figure 2 A fixed frame 7 is bolted to the side of the movable frame 3 away from the support 1. The fixed frame 7 is located on the movable frame 3 at the end away from the translation drive 41. The fixed frame 7 is L-shaped. The axial direction of the rotating shaft 6 is parallel to the length direction of the fixed frame 7. The rotating drive 5 is bolted to the side of the fixed frame 7 near the translation drive 41. The output shaft of the rotating drive 5 passes through the fixed frame 7 and is fixedly fitted with a connecting sleeve 11. The end of the connecting sleeve 11 away from the rotating drive 5 is fitted onto the rotating shaft 6. When the rotating drive 5 is started, the rotating drive 5 drives the connecting sleeve 11 to rotate, and then the connecting sleeve 11 drives the rotating shaft 6 to rotate synchronously.

[0033] Reference Figure 1 The fixed frame 7 is fixed with a support seat 8 by bolts. In this embodiment, there are two support seats 8, which are spaced apart on the fixed frame 7. The rotating shaft 6 passes through the support seat 8 and is rotatably connected to the support seat 8 through a bearing. The support seat 8 provides radial support for the rotating shaft 6, reducing the radial offset of the rotating shaft 6 due to gravity during rotation, which helps to improve the stability of the rotation of the rotating shaft 6.

[0034] Reference Figure 1 A pressing element 12 is radially inserted on the connecting sleeve 11. The fixing bracket 7 is fixed with a first rotary switch 9 and a second rotary switch 10 by bolts on the side near the support base 8. The first rotary switch 9 is located to the right of the second rotary switch 10, and the two are set at an angle. When the rotary drive 5 drives the connecting sleeve 11 to rotate, the pressing element 12 will touch the first rotary switch 9 or the second rotary switch 10, thereby controlling the rearview mirror 2 to rotate and then remain in a fixed position.

[0035] Reference Figure 1 The rearview mirror 2 is fixed to the mounting bracket 18 by bolts at one end near the movable frame 3. The mounting bracket 18 is welded and fixed to the end of the rotating shaft 6 away from the connecting sleeve 11. The rearview mirror 2 is detachably connected to the rotating shaft 6 through the mounting bracket 18, which facilitates the replacement or cleaning of the rearview mirror 2 and reduces maintenance costs.

[0036] Reference Figure 2 The bracket 1 is fixed with a mounting plate 20 by bolts on the side away from the movable frame 3. The mounting plate 20 is bent and shaped towards the side closer to the movable frame 3. The mounting plate 20 is easy to install at the hinge of the car A-pillar and hood to ensure the stability of the rearview mirror 2.

[0037] The implementation principle of the retractable rearview mirror mechanism disclosed in this application embodiment is as follows: When the rearview mirror 2 needs to be folded, the rotary drive 5 drives the rearview mirror 2 to rotate upward until the pressing part 12 touches the second rotary switch 10. At this time, the rearview mirror 2 is parallel to the vehicle body, the rotary drive 5 self-locks, and the rotation process ends. Subsequently, two seconds after the second rotary switch 10 is touched, a signal is sent to the translation drive 41. The translation drive 41 drives the gear 42 and the rack 43 to mesh and transmit power, so that the slider 14 drives the moving frame 3 to move downward on the slide rail 13 until the connecting rod 16 touches the downward limit switch 15. At this time, the translation drive 41 self-locks, and the downward movement of the rearview mirror 2 is completed. Through the combined movement of rotation and downward movement, the rearview mirror 2 can be integrated into the side of the vehicle body hood, effectively improving the overall sense of the vehicle and the sense of technology, and further reducing wind resistance.

[0038] When the rearview mirror 2 needs to be unfolded, the translation drive 41 is activated, driving the moving frame 3 and the rearview mirror 2 to move upward along the slide rail 13 until the connecting rod 16 touches the upward limit switch 17. At this time, the translation drive 41 self-locks. Then the rotation drive 5 is activated, driving the pressing part 12 on the connecting sleeve 11 and the rearview mirror 2 to rotate synchronously until the pressing part 12 touches the first rotation switch 9. At this time, the rotation drive 5 self-locks, stopping the rotation of the rearview mirror 2, thus completing the unfolding function of the rearview mirror 2.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
