[0030] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.
[0031] Figure 1 The utility model is a structural schematic diagram of a rearview mirror angle detection device.
[0032] from Figure 1 It can be seen that the rearview mirror angle detection device includes: a base 1, a side cover structure 2, a rocker device 3, and an angle sensor 4.
[0033] exist Figure 1 In an optional embodiment, the base 1 includes a mounting hole 12, and a bolt passes through the mounting hole 12 to fix the base 1 on the user's product, which may be, but is not limited to, a car. Meanwhile, in this embodiment, the number of mounting holes 12 is three, but in other embodiments of the utility model, the number of mounting holes 12 can be customized according to customer needs. The establishment of the mounting hole 12 can enhance the convenience of installation of the rearview mirror angle detection device.
[0034] Furthermore, the base 1 is also provided with an opening (see Figure 2 ), the opening is used to accommodate the angle sensor 4, and the angle sensor 4 includes a buckle 41 (see Figure 2 ). At the same time, there is a notch 13 in the opening, and the angle sensor 4 can be buckled into the notch 13 through the buckle 41 to achieve fixed installation with the base 1. This fixing method can better achieve a firm and stable installation of the angle sensor 4 and the base 1. It should be noted that the buckle 41 corresponds to the notch 13 one by one, but the specific number of the buckle 41 and the notch 13 is not fixed, and it is determined by the technicians in this field according to the actual situation.
[0035] exist Figure 1 In an optional embodiment, the base 1 further has a connection hole 11, the side cover structure 2 is located on one side of the connection hole 11, and the rocker device 3 is located on the other side of the connection hole 11, and the side cover structure 2 and the rocker device 3 can be fixed in the connection hole 11 by bolts. The connection mode is a movable connection, so the rocker device 3 can rotate. At the same time, the rotation of the rocker device 3 can drive the side cover mechanism to rotate.
[0036] Specifically, a permanent magnet 21 (see Figure 3), the permanent magnet 21 can release magnetic force, and the permanent magnet 21 is fixedly installed in the side cover mechanism. Therefore, as the side cover mechanism rotates with the rocker device 3, the permanent magnet 21 also rotates around the center of the side cover structure 2. While the permanent magnet 21 rotates, the angle sensor 4 can detect the angle of rotation through the magnetic field released by the permanent magnet 21. At the same time, the angle sensor 4 converts the detected angle data into an electrical signal.
[0037] from Figure 1 It can be seen that the rearview mirror angle detection device further includes a connector 5, a wiring harness 6 and a chip 7. The connector 5 in an optional embodiment of the utility model can be, but is not limited to, a connecting plug, and the connector 5 is connected to the angle sensor 4. At the same time, one side of the wiring harness 6 is connected to the connector 5, and the other side of the wiring harness 6 is connected to the chip 7. The electrical signal converted by the angle sensor 4 passes through the connector 5 and the wiring harness 6, and is then input into the chip 7.
[0038] Specifically, the chip 7 receives the electrical signal detected by the angle sensor 4, processes the electrical signal, determines the rotation angle of the permanent magnet 21, and then calculates the rotation angle of the rearview mirror, thereby completing the detection of the rearview mirror angle detection device. In an optional embodiment of the utility model, the chip 7 can be, but is not limited to, a single chip microcomputer.
[0039] Furthermore, the rearview mirror angle detection device further includes a housing 8, in which the chip 7 is installed, and the housing 8 protects the chip 7. It should be specifically noted that the shielded wire in the wiring harness 6 can effectively prevent the wiring harness 6 from being affected by external electromagnetic interference, collision interference, etc., thereby improving the accuracy of detection.
[0040] Figure 2 The utility model is a bottom view of a rearview mirror angle detection device.
[0041] from Figure 2 It can be clearly seen that the base 1 has an opening for accommodating the angle sensor 4, and the opening has a notch 13. At the same time, the angle sensor 4 has a buckle 41, and the angle sensor 4 can be fixed in the base 1 through the cooperation of the buckle 41 and the notch 13. This fixing method is convenient and firm. At the same time, due to the firm fixing, it is not easy to loosen, which can significantly improve the accuracy of detection.
[0042] Figure 3 It is a partial schematic diagram of a rearview mirror angle detection device of the utility model.
[0043] from Figure 3 It can be seen that the side cover structure 2 has a permanent magnet 21, and the permanent magnet 21 is fixedly installed in the side cover structure 2. Figure 1As described in the figure, since the rocker device 3 and the side cover structure 2 are movably connected to the two sides of the connection hole 11 of the base 1 through bolts, when the rearview mirror rotates, the rocker device 3 also rotates, and the rocker device 3 can drive the side cover structure 2 to rotate, and the permanent magnet 21 also rotates. The angle sensor 4 detects the magnetic field of the permanent magnet 21 and converts the detection result into an electrical signal. The electrical signal is input into the chip 7 through the connector 5 and the wiring harness 6. The chip 7 processes the electrical signal to obtain the detection result.
[0044] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
