Description

Technical Field

[0001] The utility model belongs to the technical field of electronic rearview mirrors, and in particular relates to a CMS electronic rearview mirror with a heat dissipation function. Background Art

[0002] An electronic rearview mirror is an indirect vision device that uses a system consisting of a camera and monitor to obtain a specified field of view. It incorporates a high-definition camera, digital visual processing system, safety system, LCD display, and other electronic devices, and is a new type of rearview mirror that can replace traditional optical rearview mirrors.

[0003] The field of view of traditional rearview mirrors is limited by the structure and angle of the vehicle body, and the images that the driver can see are often limited. Electronic rearview mirrors are generally designed with a main lens and a wide-angle lens. Usually, an OLED module is installed in the electronic rearview mirror to present images through a touch screen, thereby providing a wider field of view, eliminating blind spots, helping drivers better understand the surrounding environment, and reducing the occurrence of accidents. However, the installation of working components in the electronic rearview mirror will cause the internal temperature of the electronic rearview mirror to reach a high level when working, thereby affecting the service life of the electronic rearview mirror. In view of this, the present invention is a CMS electronic rearview mirror with a heat dissipation function to solve the above problem. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0024] like Figures 1 to 7 shown

[0025] A CMS electronic rearview mirror with a heat dissipation function includes a rearview mirror housing 1, a mounting opening 13 is provided on one side of the rearview mirror housing 1, a cover plate 6 is installed on the inner wall of the mounting opening 13, and equidistantly distributed air vents 7 are provided on the cover plate 6. A dustproof mesh plate 17 is fixedly provided on one side of the cover plate 6 close to the inside of the rearview mirror housing 1. By installing the dustproof mesh plate 17 on the cover plate 6, a dustproof effect can be achieved to prevent external dust from entering the inside of the rearview mirror housing 1. A connecting rod 8 is fixedly connected to one side of the cover plate 6 located outside the rearview mirror housing 1, and symmetrically arranged mounting plates 5 are fixedly connected at both ends of the connecting rod 8. Symmetrically arranged heat dissipation ports 3 are provided on both sides of the rearview mirror housing 1, and filter screen plates 4 are installed on the inner walls of the two heat dissipation ports 3. The filter screen plates 4 provided can achieve a dustproof effect to prevent external dust and debris from entering the rearview mirror housing 1. On the inner side of the rearview mirror housing 1, two mounting plates 5 are respectively fixedly connected to the outer wall of one side of the two filter plates 4. A symmetrically arranged mounting groove 14 is provided on one side of the rearview mirror housing 1, and the mounting groove 14 is communicated with the heat dissipation port 3. The two mounting plates 5 are respectively slidably arranged on the inner walls of the two mounting grooves 14. The inner walls of the opposite sides of the rearview mirror housing 1 are each installed with a mounting housing 15 by bolts. A cooling fan 18 is installed on the inside of the two mounting housings 15. The two mounting housings 15 are respectively located on one side of the two heat dissipation ports 3. A symmetrically arranged ventilation port 16 is provided on the opposite side of the two mounting housings 15. When the cooling fan 18 is started, the heat generated by the electronic rearview mirror during operation can enter the mounting housing 15 through the ventilation port 16, and then be dissipated to the outside of the rearview mirror housing 1 through the heat dissipation port 3, thereby improving the heat dissipation effect.

[0026] In a specific embodiment, a touch screen 2 is installed on the side of the rearview mirror housing 1 away from the cover plate 6, an OLED module 10 is installed on one side of the touch screen 2, a heat conducting plate 11 is installed on one side of the OLED module 10, and a heat sink 12 is installed on one side of the heat conducting plate 11. The OLED module 10, the heat conducting plate 11 and the heat sink 12 are all arranged on the inner side of the rearview mirror housing 1. Through the provided heat conducting plate 11 and the heat sink 12, the heat generated by the touch screen 2 and the OLED module 10 during operation can be transferred to the heat sink 12 through the heat conducting plate 11, and then through the air vents 7 opened on the cover plate 6, part of the heat transferred to the heat sink 12 can be dissipated to the outside of the rearview mirror housing 1 through the air vents 7.

[0027] Furthermore, a symmetrically arranged fixing plate 9 is fixedly installed on one side of the cover plate 6, and the fixing plate 9 is installed on the rearview mirror housing 1 by bolts. After long-term use, the fixing plate 9 is removed from the rearview mirror housing 1. After the disassembly is completed, the cover plate 6 is pulled to move by the connecting rod 8, so that the cover plate 6 drives the dustproof screen plate 17 to move to the outside of the rearview mirror housing 1. At the same time, the connecting rod 8 drives the two mounting plates 5 to move, so that the two mounting plates 5 can drive the two filter screens 4 to move until the cover plate 6 is removed from the rearview mirror housing 1, and the two filter screens 4 are moved to the outside of the rearview mirror housing 1, so that the dustproof screen plate 17 and the filter screen plate 4 can be removed for cleaning.

[0028] The implementation principle of a CMS electronic rearview mirror with heat dissipation function in this embodiment is as follows:

[0029] During specific use, the heat generated by the touch screen 2 and the OLED module 10 during operation can be transferred to the heat sink 12 through the heat conduction plate 11, and then part of the heat transferred to the heat sink 12 can be dissipated to the outside of the rearview mirror housing 1 through the air vents 7 opened on the cover plate 6. The dustproof mesh plate 17 installed on the cover plate 6 can play a dustproof role to prevent external dust from entering the inside of the rearview mirror housing 1. Then, the cooling fan 18 is started to work, so that the heat generated by the electronic rearview mirror during operation can enter the installation housing 15 through the vents 16, and then be dissipated to the outside of the rearview mirror housing 1 through the heat dissipation port 3, thereby improving the heat dissipation. The dust filter 4 is provided to prevent external dust and debris from entering the inner side of the rearview mirror housing 1. After long-term use, the fixing plate 9 is removed from the rearview mirror housing 1. After the removal is completed, the cover plate 6 is pulled by the connecting rod 8 to move, so that the cover plate 6 drives the dustproof screen plate 17 to move to the outside of the rearview mirror housing 1. At the same time, the connecting rod 8 drives the two mounting plates 5 to move, so that the two mounting plates 5 can drive the two filter screens 4 to move until the cover plate 6 is removed from the rearview mirror housing 1. At the same time, the two filter screens 4 are moved to the outside of the rearview mirror housing 1, so that the dustproof screen plate 17 and the filter screen plate 4 can be removed for cleaning.
