Description

Technical Field

[0001] The utility model relates to the technical field of electronic rearview mirrors, in particular to an electronic rearview mirror capable of quickly adjusting the angle of a camera. Background Art

[0002] Electronic rearview mirrors are an advancement in modern automotive technology. They replace traditional mechanical rearview mirrors by integrating electronic displays and corresponding camera systems. Electronic rearview mirrors use cameras installed at the rear of the vehicle to capture rear images and display them on the display screen inside the car, which eliminates the mirror reflections of traditional rearview mirrors and provides a clearer, wider-angle field of view. Equipped with night vision function, they can automatically adjust brightness and contrast to provide better visibility at night or in low light conditions. The cameras of electronic rearview mirrors can provide a wider field of view. They help reduce blind spots behind the vehicle and help reduce wind resistance and improve the overall aerodynamic performance of the vehicle. At the same time, they can be integrated with other intelligent systems of the vehicle, such as navigation systems, driving assistance systems, etc., to provide a more convenient driving experience and higher integration.

[0003] Currently, existing electronic rearview mirrors need to adapt to vehicles of different heights and widths, so when installing, it is necessary to select a suitable installation location and adjust the angle by adjusting the camera to achieve the best viewing angle coverage. Since electronic rearview mirrors are usually installed above the door of the commercial vehicle cab, the position is relatively high, so the installation and commissioning process requires the use of a climbing device and proper safety precautions. However, there are several disadvantages:

[0004] 1. A climbing device is required to open the cover, and then adjust and install the camera. It is fixed with multiple screws, which is inconvenient to disassemble and adjust. As a result, the installation is time-consuming and costly, and the requirements for the installation site are high, and there are certain safety hazards.

[0005] 2. When tightening the screws to secure the camera, the relative rotation and friction between the screw flange and the bracket's support surface can cause the camera to slip, shifting the rearview mirror's viewing angle. At the same time, long-term vibration and creep of the screw material can weaken the lateral friction, leading to camera tightening failure.

[0006] 3. The camera angle can only be adjusted by directly pinching the camera with your hands and turning it. Fine adjustment of the angle is not possible, and the adjustment must rely on the personnel in the cab to check the image on the display screen and then issue instructions, which makes the installation efficiency very low. Utility Model Content

[0007] (1) Technical problems solved

[0008] In response to the deficiencies of the existing technology, the present invention provides an electronic rearview mirror that can quickly adjust the camera angle, which has the advantages of being able to quickly and effectively adjust the camera, and solves the problem of the cumbersome and complicated adjustment methods at this stage.

[0009] (2) Technical solution

[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electronic rearview mirror with a quickly adjustable camera angle, comprising a housing assembly and a camera assembly, wherein the housing assembly comprises a connecting arm for mounting the electronic rearview mirror as a whole on a car, a rearview mirror top cover being fixed at one end of the connecting arm, and a rearview mirror bottom cover being fixed at the bottom of the rearview mirror top cover; when the rearview mirror top cover and the bottom cover are closed, protection is provided for the internal camera assembly, thereby preventing the camera assembly from being directly exposed to the outside and easily damaged.

[0011] The camera assembly includes a mounting bracket fixed between the top cover and the bottom cover of the rearview mirror, a rotating bracket and an adjusting bracket movably connected in the mounting bracket, a linkage gear is provided on the side of the rotating bracket, a transmission card tooth is provided on the side of the adjusting bracket, the transmission card tooth is meshed with the linkage gear, and the camera is fixed in the rotating bracket. In addition, a rear baffle is fixed to the rear side of the mounting bracket, a screw pressure block is fixed to the bottom of the rear baffle, and an adjusting screw is movably hinged between the rear baffle and the screw pressure block, and a regulating interface is provided on the adjusting bracket, one end of the regulating screw is threadedly connected to the regulating interface, and the other end passes through the bottom of the screw pressure block, and a sliding groove is provided in the mounting bracket to limit the upward and downward movement of the adjusting bracket. The adjusting bracket is moved up and down by rotating the regulating screw clockwise or counterclockwise, and the rotating bracket drives the camera to swing up and down under the action of the transmission card tooth and the linkage gear meshing, thereby adjusting the viewing angle of the camera.

[0012] When installing and using the electronic rearview mirror that can quickly adjust the camera angle, insert one end of the hexagonal wrench into the docking hole, and ensure that the other end of the hexagonal wrench is inserted into the interface at the bottom end of the adjusting screw, and adjust the camera angle up or down as needed, and rotate it according to the prompt text around the docking hole, so that the rod of the adjusting screw is connected with the inner thread of the adjusting interface, so that the adjusting bracket moves up and down in the mounting bracket, and the rotating bracket drives the camera to swing up and down under the force of the engagement of the transmission gear and the connecting gear, and the camera angle of view is adjusted to the required angle.

[0013] As a further improvement of the above solution, a docking hole is provided at the bottom of the rearview mirror bottom cover, which corresponds to the bottom end of the regulating screw. At the same time, a hexagonal wrench is movably sleeved in the docking hole, and one end of the hexagonal wrench is inserted into one end of the regulating screw.

[0014] Through the above technical solution, an inner hexagonal slot is provided at one end of the regulating screw connected to the hexagonal wrench, and the shape and diameter of the hexagonal wrench match those of the inner hexagonal slot. When one end of the hexagonal wrench is inserted from the docking hole, the inserted end of the hexagonal wrench is inserted into the interface of the regulating screw, so that when the hexagonal wrench is turned, the regulating screw can be driven to rotate at the same time.

[0015] As a further improvement of the above solution, a guide groove is provided on the side of the mounting bracket, and a guide bone is provided on the side of the rotating bracket, and the guide bone is slidably connected in the guide groove.

[0016] Through the above technical solution, two coaxial groups of guide grooves and guide bones are respectively provided on both sides of the mounting bracket and the rotating bracket to limit the arc-shaped bone position of the rotating bracket, which rotates around the rotating axis of the guide groove of the mounting bracket to realize the function of axisless rotation. The guide groove and the guide bone are both arranged in an arc shape, so that when the adjusting bracket moves up and down, the rotating bracket rotates, and at the same time the guide bones on the side slide in the guide groove, thereby improving the stability of the rotating bracket in the mounting bracket.

[0017] As a further improvement of the above solution, one end of the camera passes through the rearview mirror top cover and one end of the rearview mirror bottom cover.

[0018] Through the above technical solution, a hole is opened at one end of the top cover and the bottom cover of the rearview mirror, which matches the viewing angle range of the camera, and the camera passes through the hole, so that when the camera is adjusted, the camera can clearly correspond to the required environmental viewing angle.

[0019] As a further improvement of the above solution, a rubber ring is movably connected between the rear baffle and the screw pressing block, and the rubber ring is fitted on one end of the regulating screw.

[0020] Through the above technical solution, the rubber ring is used to increase the nut of the regulating screw and leave a set compression amount to eliminate the axial clearance between the screw and the bracket to avoid loosening. At the same time, the friction generated by the rotation can also provide a certain damping feel when turning the hex wrench, thereby improving the user experience.

[0021] As a further improvement of the above solution, a self-tapping screw is installed on the screw pressing block, one end of the self-tapping screw passes through the rear baffle and is threadedly connected to the mounting bracket.

[0022] Through the above technical solution, the self-tapping screws are used to fix the screw block and the rear baffle on the mounting bracket to avoid loosening.

[0023] Compared with the existing technology, the present invention provides an electronic rearview mirror that can quickly adjust the camera angle, which has the following beneficial effects:

[0024] 1. The electronic rearview mirror capable of quickly adjusting the camera angle is configured such that one end of a hexagonal wrench is inserted into the docking hole and then plugged into the interface at the tail end of the regulating screw. By rotating the screw, the regulating bracket moves up and down under the force of the internal thread connection between the screw and the regulating interface. At this time, the rotating bracket drives the internally installed camera to rotate and adjust under the force of the engagement between the transmission teeth and the linkage gear, thereby enabling the camera to be adjusted quickly and effectively.

[0025] 2. This electronic rearview mirror can quickly adjust the camera angle. When the bracket is adjusted up and down, the bracket is rotated to rotate. At the same time, the guide bones on the side slide in the guide groove, thereby improving the stability of fine-tuning. This effectively solves the problem that manual adjustment cannot achieve the fine-tuning effect and it takes a long time to reach the standard viewing angle, further improving its practicality.
