Description
Technical Field
[0001] This utility model relates to the field of sensors, and in particular to a sensor for controlling the angle of a rearview mirror. Background Technology
[0002] In the automotive industry, exterior rearview mirrors are crucial for drivers to obtain a clear view of the outside world. To meet the different vision needs of drivers, there are various ways to adjust the mirrors, the most common being manual exterior adjustment, manual interior cable adjustment, and electric interior adjustment.
[0003] Electric rearview mirrors use an in-car adjustment switch to control the forward and reverse rotation of two motors in the electric commutator, enabling left and right adjustment of the mirrors. However, with the development of automotive intelligence, the problems of ordinary electric commutators have become apparent.
[0004] It lacks a position signal sensor and cannot quantify position changes to store the mirror's position. When switching between reversing and moving forward, the rearview mirrors must be manually adjusted multiple times, which is cumbersome and results in inconsistencies in position each time, affecting the stability and accuracy of the field of vision and threatening driving safety. For example, after parking and restarting, the driver has to readjust the rearview mirrors, distracting their attention from the road. Utility Model Content

When the rearview mirror switches its rotation direction, the gear drive unit switches its rotation direction synchronously.
[0009] A connecting component is disposed inside the base and connected to gear drive units at both ends of the bracket.
[0010] The aforementioned components achieve the following effects: By setting up the sensor body, including a base, a gear drive unit, and a connecting assembly, a bracket extends from the base, providing a mounting foundation for other components. The gear drive unit consists of first and second gear drive assemblies respectively arranged at both ends of the bracket. These assemblies can be connected to the rearview mirror and switch synchronously when the rearview mirror's rotation direction changes. This optimizes the overall sensor structure, making rearview mirror angle control more timely and accurate during direction changes, avoiding angle control problems caused by untimely response. The connecting assembly connects to the gear drive unit, ensuring the stability of the coordinated operation of all parts and contributing to precise control of the rearview mirror angle.

The conductive elements contact the resistive layers via sliding contacts. Utilizing the sliding contact connection between the resistive layers and the conductive elements, the physical signal of gear rotation can be effectively converted into an electrical signal, providing a signal basis for accurately controlling the rearview mirror angle. Through precise electrical signal feedback, the accuracy of rearview mirror angle control can be improved. Simultaneously, by changing the resistance value connected between the two sliding contacts, the sensor can detect the rotation angle of the rearview mirror, thus acquiring the rearview mirror angle data after left and right adjustments, and storing this angle data.

This ensures accurate and rapid signal transmission between the components, enabling the various parts of the sensor to work collaboratively. This guarantees the timeliness and accuracy of rearview mirror angle control, reducing angle control delays or deviations caused by poor signal transmission.
[0017] Preferably, the outer resistor layer has a first connection point connected to the first pin and a second connection point connected to the second pin, and the inner resistor layer has a third connection point. The third pin and the fourth pin are respectively connected to the gear drive assembly and the second gear drive assembly through the third connection point.
[0018] The aforementioned components achieve the following effect: by setting a first and second connection points on the outer resistor layer and a third connection point on the inner resistor layer, with the third and fourth pins connected to the assembly via the third connection point, the connection relationship between each pin and the resistor layer is further clarified, the electrical connection structure is optimized, and the stability and reliability of signal transmission are improved. This, in turn, ensures the accurate transmission of the rearview mirror angle control signal, and enhances the stability and precision of the rearview mirror angle control.
[0019] Preferably, the first connection point, the second connection point, and the third connection point are all provided with connecting pins for electrical connection of the connecting components.
[0020] The effect achieved by the above components is as follows: by arranging connecting pins on the first connection point, the second connection point and the third connection point, the connecting pins can enhance the reliability of the electrical connection between the connecting components and the resistive layer, reduce the contact problems caused by factors such as vehicle driving vibration and temperature changes, ensure the stability of sensor signal transmission, and enable the rearview mirror angle control to be continuously and stably performed, avoiding abnormal angle control caused by unreliable connection.

The gears are rotatably connected to the bracket through the gear connecting parts. A limiting block for limiting the conductive element is provided on the upper edge of the gear connecting part.
[0022] The aforementioned components achieve the following effect: by setting gear connecting parts at both ends of the bracket, the gears are rotatably connected to the bracket through the gear connecting parts, and limiting blocks are set in the gear connecting parts to limit the conductive elements. On the one hand, this ensures the stability of gear rotation, and on the other hand, it limits the conductive elements, preventing them from shifting during gear rotation. This ensures a stable and reliable sliding contact connection between the conductive elements and the resistive layer, thereby guaranteeing the accuracy of the sensor signal output and improving the precision and stability of rearview mirror angle control.
[0023] Preferably, the base has a plurality of interfaces for fixing and connecting components.
[0024] The effect achieved by the above components is as follows: by opening several interfaces in the base for fixing the connecting components, the connecting components can be firmly fixed in the base, ensuring the stability of the connecting components during vehicle operation, avoiding the impact of loose connecting components on the electrical connection and collaborative work between the components, ensuring the overall performance stability of the sensor, and providing a guarantee for the accurate and stable control of the rearview mirror angle.

[0057] In this embodiment 2,
[0058] like Figures 1 to 3 As shown, the sensor body 1 includes a base 2, a gear drive unit 4, and a connecting component 7. The layout and connection relationships are optimized, simplifying the structure and reducing manufacturing difficulty and cost. The gear drive unit 4 includes a first gear drive component 5 and a second gear drive component 6, respectively arranged at both ends of the bracket 3. They can switch synchronously when the rearview mirror changes rotation direction, achieving precise and rapid response, avoiding delays, jamming, and angle deviations, thus improving driving safety. Inside the first gear drive component 5, a gear 8, a circuit board 9, and conductive elements 10 are arranged. A resistive layer and the conductive elements 10 are connected by sliding contact to convert physical signals into electrical signals, improving control accuracy.

[0059] In this embodiment 3,
[0060] like Figures 1 to 3 As shown, when the rearview mirror angle needs to be adjusted, an external force is applied to the rearview mirror, causing it to rotate. At this time, the gear drive unit 4, which is connected to the rearview mirror, starts to work. The first gear drive assembly 5 and the second gear drive assembly 6 in the gear drive unit 4 are respectively arranged at both ends of the bracket 3. Due to their connection with the rearview mirror, they will synchronously switch the rotation direction as the rotation direction of the rearview mirror changes.

The circuit board 9 inside gear 8 has an arc-shaped outer resistive layer 11 and an inner resistive layer 12. Two sliding contacts 13, protruding along the outer and inner resistive layers 11 and 12 on the conductive element 10, slide on the resistive layers as gear 8 rotates. This sliding contact connection ensures that the two contacts 13 are always in contact with the outer and inner resistive layers 11 and 12 respectively, thus changing the resistance value in the circuit according to the change in the contact position. Because the outer resistive layer 11 has a first connection point 18 connected to the first pin 14 and a second connection point 19 connected to the second pin 15, and the inner resistive layer 12 has a third connection point 20, with the third pin 16 and fourth pin 17 connected to the gear drive assembly and the second gear drive assembly 6 respectively through the third connection point 20, changes in resistance value transmit corresponding electrical signals through the pins in the connection assembly 7.

The electrical signal is accurately and quickly transmitted to the relevant control unit through each pin. The control unit determines the rotation angle and direction of the rearview mirror based on the received electrical signal, and issues commands accordingly to precisely adjust the angle of the rearview mirror.
[0063] Meanwhile, the gear connecting parts 22 at both ends of the bracket 3 ensure the stability of the rotation of the gear 8, and the limiting blocks 23 set on them restrict the position of the conductive element 10 to prevent it from shifting, ensuring a stable sliding contact connection between the conductive element 10 and the resistive layer, and ensuring accurate signal output. The interface 24 in the base 2 for fixing the connecting assembly 7, and the connecting pin 21 on the connection point, further ensure the stability of the entire sensor structure and the reliability of the electrical connection, enabling the sensor to work continuously and stably and accurately control the rearview mirror angle.
