Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an electronic exterior rearview mirror flip-up and telescopic linkage mechanism. Background Technology

[0002] Throughout the development of the automotive industry, exterior rearview mirrors have always been a crucial component. Drivers can use these mirrors to observe the sides and rear of the vehicle, reducing potential risks during driving. With the increasing intelligence and electrification of automobiles, electronic exterior rearview mirrors are becoming more widely used. Compared to traditional physical exterior rearview mirrors, electronic mirrors not only provide a clearer and wider field of vision but can also be integrated with the vehicle's electronic systems to achieve functions such as automatic adjustment and blind spot detection.

[0003] Electronic side mirrors use cameras to capture images, allowing for more flexible installation locations, such as near the front of the vehicle, like the hood. However, while these mirrors can avoid interference with the hood by adjusting their angle, they lack mechanisms to prevent collisions with the vehicle body. In the event of a malfunction, the mirror could damage the vehicle or jam other components, making repairs difficult.

[0004] Regarding the aforementioned technologies, there are drawbacks that electronic exterior rearview mirrors may damage the vehicle body or jam body parts when they malfunction, making them difficult to repair. Utility Model Content

[0005] In order to avoid damage to the vehicle body and jamming of vehicle body parts by electronic exterior rearview mirrors, this application provides an electronic exterior rearview mirror flip-telescopic linkage mechanism.

[0006] The electronic exterior rearview mirror flip-up and telescopic linkage mechanism provided in this application adopts the following technical solution:

[0007] An electronic exterior rearview mirror flip-up and telescopic linkage mechanism includes:

[0008] A flip-up assembly for mounting the camera;

[0009] A sliding component is rotatably connected to the flipping component, and the sliding component is slidably disposed on the base component. The sliding component includes a first motor, a second motor, and a flipping limit switch. The first motor is used to drive the flipping component to flip, the second motor is used to drive the sliding component to slide, and the flipping limit switch is used to turn off when the flipping component flips to a preset flipping position to shut off the first motor.

[0010] The base assembly includes a sliding limit switch, which is used to turn off the second motor when the sliding assembly slides to a preset sliding position.

[0011] By adopting the above technical solution, the cooperation of the flip limit switch, the sliding limit switch, the first motor and the second motor can prevent the electronic exterior rearview mirror flip telescopic linkage mechanism from damaging the vehicle body and jamming the parts on the vehicle body due to excessive rotation or excessive extension, thereby improving the safety and stability of the device.

[0012] Optionally, the flipping assembly includes a flipping bracket, and a camera hole is provided at the first end of the flipping bracket for mounting the camera.

[0013] By adopting the above technical solution, and by setting a camera hole for mounting the camera on the first end of the flip bracket, the installation of the camera is more stable and reliable, the captured image is more stable, and the driver is provided with more accurate rear view information, which helps to improve driving safety.

[0014] Optionally, the flipping assembly further includes a connector connected to a second end of the camera bracket away from the first end, and the connector is provided with a rotating shaft; the sliding assembly includes a sliding bracket rotatably connected to the rotating shaft.

[0015] By adopting the above technical solutions, the design of the connectors and the rotating shaft makes the connection between the flipping component and the sliding component more stable and flexible, ensuring that the flipping component can perform flipping actions smoothly and improving the stability and reliability of the flipping process.

[0016] Optionally, the first motor is mounted on the sliding bracket; one end of the rotating shaft is provided with a coupling, which is connected to the output shaft of the first motor, and the first motor is used to drive the coupling to rotate, so as to drive the flipping assembly to flip.

[0017] By adopting the above technical solution, the output shaft of the first motor is connected to the rotating shaft through a coupling, enabling the first motor to precisely drive the flipping component to flip, thereby improving the accuracy and stability of the flipping action and ensuring that the electronic exterior rearview mirror can accurately reach the predetermined position when it needs to be flipped.

[0018] Optionally, the flip limit switch includes a first flip limit switch and a second flip limit switch, both of which are disposed on the sliding bracket. The flip preset position includes a first flip preset position and a second flip preset position. When the first motor drives the flip component to flip to the first flip preset position, the first flip limit switch is turned off to shut down the first motor. When the first motor drives the flip component to flip to the second flip preset position, the second flip limit switch is turned off to shut down the first motor.

[0019] By adopting the above technical solution, the first flip limit switch and the second flip limit switch can effectively prevent the flip component from flipping excessively, thereby improving the safety and reliability of the electronic exterior rearview mirror flip telescopic linkage mechanism.

[0020] Optionally, the base assembly includes a base bracket and a track disposed on the base bracket; the sliding assembly further includes a slider disposed on the sliding bracket, the slider being located in the track and capable of sliding in the track.

[0021] By adopting the above technical solution, the sliding component can slide smoothly on the base component through the cooperation of the slider and the track, which improves the stability and smoothness of the sliding process and provides reliable mechanical support and guidance for the telescopic and concealing function of the electronic exterior rearview mirror.

[0022] Optionally, the base assembly further includes a rack disposed on the base support, the second motor is disposed on the sliding support, and a gear is disposed on the output shaft of the second motor. The gear meshes with the rack, and the second motor is used to drive the gear to rotate, thereby causing the sliding assembly to move relative to the base assembly.

[0023] By adopting the above technical solution, the rack and gear on the base assembly can ensure the smooth movement and accurate positioning of the sliding assembly, thereby improving the reliability and stability of the telescopic movement of the electronic exterior rearview mirror.

[0024] Optionally, the sliding limit switch includes a first sliding limit switch and a second sliding limit switch, both of which are mounted on the base bracket. The sliding preset position includes a first sliding preset position and a second sliding preset position, wherein: when the second motor drives the sliding component to slide to the first sliding preset position, the first sliding limit switch is turned off to shut down the second motor; when the second motor drives the sliding component to slide to the second sliding preset position, the second sliding limit switch is turned off to shut down the second motor.

[0025] By adopting the above technical solution, the first sliding limit switch and the second sliding limit switch can effectively prevent the sliding component from sliding excessively, prevent the sliding component from colliding with other parts or the vehicle body, and ensure the stability of the electronic exterior rearview mirror during the extension and retraction process.

[0026] Optionally, a control module is also included, which is electrically connected to the first motor, the second motor, the first flip limit switch, the second flip limit switch, the first sliding limit switch and the second sliding limit switch to control the electronic exterior rearview mirror flip-telescopic linkage mechanism.

[0027] By adopting the above technical solution, the first motor, the second motor, and each limit switch are electrically connected to the control module, enabling the electronic exterior rearview mirror flipping and telescopic linkage mechanism to achieve automated control. This improves the convenience and intelligence of operation, allowing drivers to automatically flip and telescopically hide the electronic exterior rearview mirrors when they need to, thus enhancing the user experience.

[0028] Optionally, the base bracket is provided with a circular hole for accommodating the first motor.

[0029] By adopting the above technical solution, the circular hole design ensures that the first motor will not touch the base bracket during the movement of the sliding component, and also makes the electronic exterior rearview mirror flip-up and telescopic linkage mechanism more compact.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By cooperating with the flip limit switch, the sliding limit switch, the first motor and the second motor, the electronic exterior rearview mirror flip telescopic linkage mechanism can be prevented from damaging the vehicle body and jamming parts on the vehicle body due to excessive rotation or extension, thus improving the safety and stability of the device.

[0032] 2. The output shaft of the first motor is connected to the rotating shaft by a coupling, which enables the first motor to precisely drive the flipping component to flip, improving the accuracy and stability of the flipping action and ensuring that the electronic exterior rearview mirror can accurately reach the predetermined position when it needs to be flipped.

[0033] 3. The first motor, the second motor, and each limit switch are electrically connected to the control module, enabling the electronic exterior rearview mirror flipping and telescopic linkage mechanism to achieve automated control, improving the convenience and intelligence of operation. This allows drivers to automatically flip and telescopically hide the electronic exterior rearview mirrors when they need to do so, enhancing the user experience.

[0034] 4. The circular hole design prevents the first motor from touching the base bracket as it moves with the sliding component, and also makes the electronic exterior rearview mirror flip-up and telescopic linkage mechanism more compact. Attached Figure Description

Detailed Implementation

[0045] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0046] This application discloses an electronic exterior rearview mirror flip-up and telescopic linkage mechanism.

[0047] Reference Figure 1 and Figure 2 The electronic exterior rearview mirror flip-up and telescopic linkage mechanism includes a flip component 10, a sliding component 20 and a base component 30, wherein the flip component 10 is connected to the base component 30 through the sliding component 20.

[0048] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The flipping assembly 10 includes a flipping bracket 11, a connector 13, and a rotating shaft 14. The flipping bracket 11 is generally made of a high-strength metal material, such as aluminum alloy, to ensure its structural strength and stability. A camera hole 12 is provided at the first end of the flipping bracket 11 for mounting a camera. The camera hole 12 is generally circular, but can also be designed as square or other shapes depending on the specific shape of the camera. The second end of the flipping bracket 11, away from the first end, is connected to the rotating shaft 14 via the connector 13. The sliding assembly 20 includes a sliding bracket 21, which is rotatably connected to the rotating shaft 14. A coupling 15 is provided at one end of the rotating shaft 14, and a first motor 23 is provided on the sliding bracket 21. The output shaft of the first motor 23 is connected to the coupling 15 to drive the coupling 15 to rotate, thereby causing the flipping assembly 10 to flip to a preset flipping position. The first motor 23 can be a DC motor, which is characterized by convenient speed adjustment and simple control.

[0049] The sliding bracket 21 is also provided with a flip limit switch 25, which includes a first flip limit switch 25a and a second flip limit switch 25b. The preset flip position includes a first preset flip position and a second preset flip position. The coupling 15 is provided with a protrusion 15a, which is used to trigger the first flip limit switch 25a and the second flip limit switch 25b. Specifically, when the first motor 23 drives the flip assembly 10 to flip to the first preset flip position, the first flip limit switch 25a is turned off and the first motor 23 is turned off; when the first motor 23 drives the flip assembly 10 to flip to the second preset flip position, the second flip limit switch 25b is turned off and the first motor 23 is turned off.

[0050] The base assembly 30 includes a base bracket 31, a track 32 mounted on the base bracket 31, and a rack 33 mounted on the base bracket 31. The sliding assembly 20 further includes a slider 22 mounted on the sliding bracket 21 and a second motor 24 mounted on the sliding bracket 21. A gear 24a is mounted on the output shaft of the second motor 24. The base bracket 31 can be made of steel or aluminum alloy. Steel is generally manufactured using a stamping process with surface anti-corrosion treatment, while aluminum alloy is generally manufactured using a die-casting method. The slider 22 is located within the track 32 and can slide within the track 32. The gear 24a meshes with the rack 33. The second motor 24 drives the gear 24a to rotate, thereby causing the sliding assembly 20 to slide to a preset sliding position. The base assembly 30 is also used for connection with the vehicle body.

[0051] The base bracket 31 is also provided with a sliding limit switch 34, which includes a first sliding limit switch 34a and a second sliding limit switch 34b. The preset sliding position includes a first preset sliding position and a second preset sliding position. Specifically, when the second motor 24 drives the sliding component 20 to slide to the first preset sliding position, the first sliding limit switch 34a is turned off and the second motor 24 is turned off; when the second motor 24 drives the sliding component 20 to slide to the second preset sliding position, the second sliding limit switch 34b is turned off and the second motor is turned off.

[0052] The electronic exterior rearview mirror tilting and telescopic linkage mechanism also includes a control module. This control module is electrically connected to the first motor 23, the second motor 24, the first tilting limit switch 25a, the second tilting limit switch 25b, the first sliding limit switch 34a, and the second sliding limit switch 34b to control the electronic exterior rearview mirror tilting and telescopic linkage mechanism. The control module can be a microcontroller or a programmable logic controller (PLC), and can control each component through programming.

[0053] Reference Figure 7 , Figure 8 and Figure 9 When the electronic rearview mirror needs to avoid an obstacle, the first motor 23 drives the flipping component 10 to flip to the second flipping preset position, triggering the second flipping limit switch 25b, and the first motor 23 is de-energized. Then, the second motor 24 drives the sliding component 20 to slide to the second sliding preset position, triggering the second sliding limit switch 34b, and the second motor 24 is de-energized.

[0054] When the electronic rearview mirror is needed, the second motor 24 first drives the sliding component 20 to move to the first sliding preset position, triggering the first sliding limit switch 34a, and the second motor 24 is de-energized. Then, the first motor 23 drives the flipping component 10 to flip to the first flip preset position, triggering the first flip limit switch 25a, and the first motor 23 is de-energized.

[0055] Based on the working principle of the electronic exterior rearview mirror's flip-and-telescopic linkage mechanism, even if the electronic exterior rearview mirror's flip-and-telescopic linkage mechanism is accidentally de-energized during operation, there will always be a limit switch in the triggered state. The control module can then determine the position of the electronic exterior rearview mirror's flip-and-telescopic linkage mechanism and drive the corresponding motor to complete the flip-and-telescopic action as needed.

[0056] Refer again Figure 9 The base bracket 31 is provided with a circular hole 31a, which is used to accommodate the first motor 23 when the electronic rearview mirror flip telescopic linkage mechanism retracts.

[0057] The implementation principle of the electronic exterior rearview mirror flip-up and telescopic linkage mechanism in this application embodiment is as follows: by the cooperation of the flip limit switch, the sliding limit switch, the first motor and the second motor, the electronic exterior rearview mirror flip-up and telescopic linkage mechanism can avoid damage to the vehicle body and jamming of the vehicle body parts due to excessive rotation or excessive extension, thereby improving the safety and stability of the device.

[0058] 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.
