Description

Technical Field

[0001] This utility model relates to the field of rearview mirror technology, specifically to an electronic rearview mirror. Background Technology

[0002] Electronic rearview mirrors are an upgrade from traditional optical rearview mirrors. They collect road condition information through external cameras, process it, and display it on an in-vehicle screen. They aim to break through the limitations of traditional rearview mirrors, improve visibility in bad weather, enhance driving safety, and at the same time, conform to the trend of lightweight and low wind resistance in vehicle design, thus contributing to the development of intelligent and new energy vehicles.

[0003] Chinese Patent No. CN222005024U discloses an electronic rearview mirror, including a housing structure, a circuit board assembly, a display module for displaying the shooting scene, and an alarm for detecting obstacles. The circuit board assembly is disposed within the housing structure, and the display module and the alarm are both electrically connected to the circuit board assembly. The housing structure has an alarm area directly opposite the alarm. This electronic rearview mirror provides a display module for showing the shooting scene to help the driver gain a more comprehensive understanding of the vehicle's surroundings. When the vehicle approaches an obstacle, the alarm can sound to remind the driver to pay attention to safety. Thus, the driver does not need to constantly view the display module, freeing up their field of vision and further improving driving safety.

[0004] The aforementioned patent still has the following shortcomings: When the vehicle is idle, the device's display screen is exposed to the outside for a long time without effective protection, making it susceptible to scratches or cracks from external collisions. At the same time, prolonged exposure to sunlight will cause the internal components of the screen to age due to heat, shortening its service life. Furthermore, high temperatures may cause problems such as screen ghosting and display distortion, affecting the normal function and reliability of the electronic rearview mirror. Utility Model Content

[0005] This invention provides an electronic rearview mirror that solves the problems mentioned in the background section.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides an electronic rearview mirror, including a protective shell, and further comprising:

[0008] Mounting bracket, fixed to the back of the protective case;

[0009] A storage structure is set inside the protective shell, wherein the storage structure includes a rotating frame, the rotating frame is rotatably connected inside the protective shell, the rotating end of the rotating frame is fixed with a main gear, and a protective sleeve is fixed on one side of the protective shell.

[0010] A housing is located inside the rotating frame. A display module is installed on one side of the housing, and a control board is installed inside the housing. Control buttons are provided on one side of the display module.

[0011] The flip-up structure, located between the housing and the rotating frame, is used to adjust the angle of the housing horizontally.

[0012] The above technical solution transmits signals to the control board via lines, enabling the control board to control the display module to show road condition information collected by the external camera. Operators can send commands to the control board by pressing control buttons.

[0013] Furthermore, one side of the protective shell is rotatably connected to a transmission gear, and the transmission gear is meshed with the main gear. One side of the protective shell is mounted on a reducer, and a drive motor is mounted on the bottom of the reducer.

[0014] The above technical solution involves a drive motor that drives a transmission gear through a reducer, which in turn drives the main gear to rotate the rotating frame, thus housing the casing and the internal display module inside the protective casing.

[0015] Furthermore, the output shaft end of the drive motor is connected to the input shaft end of the reducer, and the output shaft end of the reducer is connected to the transmission gear.

[0016] Through the above technical solution, the power of the drive motor is transmitted to the transmission gear through the reducer. The reducer can reduce the speed and increase the torque, ensuring that the transmission gear stably drives the main gear to rotate, so that the rotating frame can drive the housing and display module to accurately complete the storage or angle adjustment action, thereby improving the reliability of power transmission and the stability of structural operation.

[0017] Furthermore, the rotating shaft of the rotating frame extends to the outside of the protective shell and is connected to the main gear, and the reducer is connected to the protective shell through a bracket.

[0018] Through the above technical solution, the connection between the rotating frame and the main gear ensures that the main gear can effectively drive the rotating frame to rotate. The reducer is fixed to the protective shell by the bracket, which enhances the stability of the reducer installation and avoids the components from loosening due to vibration during operation.

[0019] Furthermore, the flipping structure includes a connecting hinge, which is fixed to the inner wall of the rotating frame. The connecting hinge and the housing form a rotating structure. A lead screw is rotatably connected inside the housing. A moving block is threadedly connected to the outer side of the lead screw. A stepper motor is installed on one side of the lead screw. Moving arms are rotatably connected to both sides of the moving block.

[0020] With the above technical solution, when the stepper motor drives the lead screw to rotate, the moving block moves along the axis of the lead screw. Then, the moving arm pushes the housing to rotate horizontally with the connecting hinge as the fulcrum, adjusting the horizontal angle of the housing, thereby changing the horizontal orientation of the display module, so that the driver can obtain a more suitable viewing angle.

[0021] Furthermore, the movable arm extends to the outside of the housing and connects to the rotating frame, forming a rotating structure between the movable arm and the rotating frame.

[0022] Through the above technical solution, the mobile arm connects the housing to the rotating frame. Its rotating structure enables the mobile arm to push the housing to rotate around the connecting hinge as the fulcrum when it moves, thereby realizing the adjustment of the housing's horizontal angle.

[0023] Furthermore, the outer wall of the lead screw is provided with an external thread, and the inside of the moving block is provided with an internal thread that cooperates with the external thread.

[0024] Through the above technical solution, the threaded engagement between the lead screw and the moving block converts the rotational motion of the lead screw into the linear motion of the moving block, driving the moving arm to rotate the housing. The threaded transmission has self-locking properties, which can stably maintain the adjusted angle.

[0025] The above-described solution of this utility model has at least the following beneficial effects:

[0026] This invention uses a drive motor that drives a reducer to rotate a transmission gear, which in turn drives a rotating frame to rotate, thus retracting the housing and the internal display module into the protective shell. This achieves the storage and protection function of the device, effectively preventing the display module from being damaged by collisions, sunlight, dust accumulation, etc., due to exposure to the outside, extending the service life of the equipment, and ensuring the cleanliness and display clarity of the display module.

[0027] This invention uses a drive motor to rotate a rotating frame via a reducer and gear transmission. Combined with the linkage of a stepper motor drive screw, moving block, and moving arm, the display module can be flexibly adjusted in both vertical and horizontal directions. This achieves the angle adjustment function of the device, which can adapt to different driving scenarios and driver needs, expand the field of vision, and improve viewing comfort.

Detailed Implementation

[0035] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0036] like Figures 1 to 5 As shown, an embodiment of this utility model provides an electronic rearview mirror, including a protective shell 1, and further comprising:

[0037] Mounting bracket 2 is fixed to the back of protective shell 1;

[0038] Storage structure 3 is set inside the protective shell 1. Storage structure 3 includes a rotating frame 304, which is rotatably connected inside the protective shell 1. A main gear 303 is fixed to the rotating end of the rotating frame 304, and a protective sleeve 301 is fixed to one side of the protective shell 1.

[0039] The housing 6 is located inside the rotating frame 304. A display module 4 is installed on one side inside the housing 6. A control board 8 is installed inside the housing 6. A control button 5 is provided on one side of the display module 4.

[0040] The flip structure 7 is located between the housing 6 and the rotating frame 304 and is used to adjust the angle of the housing 6 in the horizontal direction.

[0041] In this embodiment of the present invention, when the electronic rearview mirror is activated, the control board 8 receives and processes external commands, transmits signals to the control board 8 through the line, and causes the control board 8 to control the display module 4 to display the road condition information collected by the external camera. At the same time, the control button 5 is in a ready-to-trigger state, and the operator can send commands to the control board 8 by pressing the control button 5. The control board 8 adjusts the display parameters of the display module 4 according to the commands.

[0042] like Figures 1 to 4 As shown, one side of the protective shell 1 is rotatably connected to the transmission gear 306, and the transmission gear 306 is meshed with the main gear 303. One side of the protective shell 1 is mounted on the reducer 302, and the bottom end of the reducer 302 is equipped with a drive motor 305. The output shaft end of the drive motor 305 is connected to the input shaft end of the reducer 302. The output shaft end of the reducer 302 is connected to the transmission gear 306. The rotating shaft of the rotating frame 304 extends to the outside of the protective shell 1 and is connected to the main gear 303. The reducer 302 is connected to the protective shell 1 through a bracket.

[0043] In this embodiment of the invention, when the display module 4 needs to be stored, the drive motor 305 is started by the control board 8, causing the drive motor 305 to run. Then, the reducer 302 reduces the output speed of the drive motor 305 and increases the torque. Subsequently, the output shaft of the reducer 302 drives the transmission gear 306 to rotate. Through the rotation of the drive main gear 303 of the transmission gear 306, the rotating frame 304 rotates inside the protective shell 1, causing the shell 6 and the display module 4 inside to move into the protective shell 1 along with the rotating frame 304, thereby realizing the storage or unfolding of the display module 4. When the main gear 303 stops rotating, the protective sleeve 301 protects the reducer 302 and transmission gear 306, thus protecting the display module 4 and preventing it from being damaged by collisions or sunlight. When the display module 4 is in normal use, the drive motor 305 drives the transmission gear 306 to rotate through the reducer 302, which in turn drives the main gear 303 to rotate the rotating frame 304 slightly in the vertical direction, and causes the housing 6 and the display module 4 to rotate in the vertical direction for angle adjustment.

[0044] like Figures 1 to 5As shown, the flipping structure 7 includes a connecting hinge 701, which is fixed to the inner wall of the rotating frame 304. The connecting hinge 701 and the housing 6 form a rotating structure. A lead screw 704 is rotatably connected inside the housing 6. A moving block 705 is threadedly connected to the outer side of the lead screw 704. A stepper motor 703 is installed on one side of the lead screw 704. Moving arms 702 are rotatably connected to both sides of the moving block 705. The moving arms 702 extend to the outer side of the housing 6 and connect to the rotating frame 304. The moving arms 702 and the rotating frame 304 form a rotating structure. An external thread is provided on the outer wall of the lead screw 704, and an internal thread that cooperates with the external thread is provided inside the moving block 705.

[0045] In this embodiment of the utility model, when it is necessary to adjust the horizontal angle of the housing 6, the stepper motor 703 is started by the control board 8, which drives the lead screw 704 to rotate. Then, the moving block 705 moves along the axis of the lead screw 704. The moving block 705 drives the moving arms 702 on both sides to move, so that the moving arms 702 push the housing 6 to rotate horizontally with the connecting hinge 701 as the fulcrum. This adjusts the horizontal angle of the housing 6, thereby changing the horizontal orientation of the display module 4, so that the driver can obtain a more suitable viewing angle, which improves the convenience and safety of driving to a certain extent.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
