Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile, especially a kind of wireless communication-based wire-free rearview mirror reversing down-folding auxiliary system. BACKGROUND

[0002] The existing vehicle generally has the function of reversing auxiliary or 360 panoramic image, and many old domestic vehicles or imported vehicles do not have it.If reversing auxiliary or 360 panoramic image is subsequently installed, the cost is relatively high, and the relatively low-cost solution is to adjust the lens of the rearview mirror by the lens adjusting motor during reversing, so that the user can better observe the scene behind, but in the prior art, the lens needs to be adjusted every time during reversing, so a rearview mirror reversing down-folding auxiliary system is needed to intelligently adjust the lens of the rearview mirror during reversing.

[0003] The characteristics and defects of similar products on the market at present are as follows:(1) a rearview mirror reversing down-folding control device of single module structure, i.e., the reversing down-folding has only one module, and the original vehicle reversing data needs to be connected by wire to control the device.The characteristics of the device are simple design principle and low cost.The defects are that the installation needs to be wired, the installation is relatively complex, the original vehicle structure is easily damaged during the wiring process, and the installation cost is relatively high.The connection position of the original vehicle reversing data is as follows: some are at the threshold strip position, some are at the tailgate reversing lamp position, and some are read on the original vehicle CAN bus or LIN bus in the vehicle.The reversing down-folding control device is generally installed near the rearview mirror or in the front door panel of the vehicle, and there is generally no reversing data on the door panel.The collection of reversing data and the down-folding device is far away, so the wire needs to be connected. CONTENT OF THE UTILITY MODEL

[0004] The main purpose of the utility model is to provide a wireless communication-based wire-free rearview mirror reversing down-folding auxiliary system that transmits signals without changing the signal structure of the original vehicle line and avoids damaging the original vehicle line and the function of the original vehicle by adopting the mode of radio frequency wireless signal communication.

[0005] The utility model provides a wireless communication-based wire-free rearview mirror reversing down-folding auxiliary system, which comprises a master control module and a slave control module.

[0006] The master control module and the slave control module are respectively connected with a host power module, and the master control module and the slave control module are respectively powered by the host power module.

[0007] A first wireless module is arranged on the master control module, and a second wireless module is arranged on the slave control module, and the master control module and the slave control module are wirelessly connected through the first wireless module and the second wireless module, and the master control module can control the working state of the slave control module.

[0008] The slave control module is connected to the right rearview mirror lens adjustment motor drive module and the lens position detection module respectively. The slave control module can obtain the position information of the right rearview mirror lens from the lens position detection module, and control the right rearview mirror lens motor to work through the right rearview mirror lens adjustment motor drive module according to the obtained position information.

[0009] The main control module is connected to the vehicle's main unit and obtains the vehicle's current working status through the main control module. If the vehicle is in reverse, the main control module adjusts the right rearview mirror lens through the slave control module so that the right rearview mirror is in a position that is more conducive to the user's reversing.

[0010] Preferably, the slave control module includes an adjustment detection module, which is connected to the right rearview mirror adjustment circuit of the vehicle host through the adjustment detection module. When the vehicle is in reverse, the vehicle host can control the slave control module through the right rearview mirror adjustment circuit, adjust the right rearview mirror lens through the slave control module, and record the position information of the right rearview mirror at this time.

[0011] Preferably, the main control module includes a reversing signal detection module, and is connected to the reversing signal line of the vehicle's main unit through the reversing signal detection module, thereby determining whether the vehicle is in a reversing state through the reversing signal detection module.

[0012] Preferably, the main control module includes a CAN bus module and a LIN bus module, and is connected to the CAN bus and LIN bus of the vehicle host through the CAN bus module and the LIN bus module, so that the vehicle's working status can be obtained through the CAN bus module and the LIN bus module.

[0013] The beneficial effects of this wireless communication-based, wire-free rearview mirror reversing tilt assist system are as follows:

[0014] 1. The main control module of this patent sends adjustment signals to the slave control module via wireless communication, thus eliminating the need to run a wire from the main control module to the slave control module. This avoids the problem of difficult wiring, making the product easier to install. At the same time, it can avoid accidents that may damage the original vehicle structure during the wiring process, making the product more practical and safer and more convenient to use.

[0015] 2. By adopting intelligent control, the right rearview mirror position can be automatically controlled according to whether the vehicle is in reversing mode, thereby empowering traditional, less intelligent cars and enabling them to provide users with a better intelligent experience.

[0016] 3. When in reverse, the user can adjust the right rearview mirror to the most suitable position through the right rearview mirror adjustment line of the original vehicle machine, and obtain the position information of the right rearview mirror at this time through the mirror position detection module, so that the right rearview mirror can be adjusted to the most suitable position every time it is automatically adjusted, and the product is more convenient to use and can better meet the use needs of customers.
