Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a control system and a vehicle. Background Art

[0002] Electronic exterior rearview mirrors have a better streamlined shape, which greatly reduces the contact area between the electronic exterior rearview mirror and the air compared to traditional glass exterior rearview mirrors, thereby reducing wind resistance and increasing cruising range. These advantages are particularly important for electric vehicles, which have an increasingly high market share. Therefore, the overall shape of the electronic exterior rearview mirror needs to be maintained as much as possible.

[0003] Electronic exterior rearview mirrors are usually composed of cameras, controllers and display screens. Due to their large number of internal parts and complex systems, the failure rate of electronic exterior rearview mirrors is significantly higher than that of traditional glass exterior rearview mirrors. Once an electronic exterior rearview mirror fails, it will affect driving safety. Utility Model Content

[0004] In view of this, the embodiments of the present application provide a control system and a vehicle, which have the advantages of high safety, little impact on the overall appearance, and reduced wind resistance.

[0005] In the first aspect, the present application provides a control system, which includes an electronic camera module, an optical lens module and a vehicle controller. The electronic camera module is used to collect image signals of the vehicle in a preset direction; the optical lens module includes an optical lens and an adjustment drive mechanism; wherein the optical lens is movably connected to a preset position of the vehicle, and the output end of the adjustment drive mechanism is dynamically connected to the optical lens; when the optical lens module enters an open state, the adjustment drive mechanism drives the optical lens to move to an open position, so that the driver can observe the preset direction through the optical lens that has moved to the position; when the optical lens module enters a closed state, the adjustment drive mechanism drives the optical lens to move to a closed position, so that the optical lens and the preset position of the vehicle are combined into a whole; the vehicle controller is electrically connected to the electronic camera module and the optical lens module, and is used to send a first control instruction to the electronic camera module, and / or, to send a second control instruction to the optical lens module; wherein the first control instruction is used to instruct the electronic camera module to turn on or off, and the second control instruction is used to instruct the optical lens module to turn on or off.

[0006] In the embodiment of the present application, the electronic camera module can be used to collect the image signal of the vehicle in the preset direction, so as to provide the driver with the field of view in the preset direction through the electronic camera module. Considering that the electronic camera module has more internal parts and a more complex system, the failure rate is higher than that of the traditional glass exterior rearview mirror. For this reason, on the basis of the electronic camera module, an optical lens module is also added in the embodiment of the present application. In this way, when the electronic camera module fails, the vehicle controller can send a second control instruction to instruct the optical lens module to turn on, and at the same time, the adjustment drive mechanism can drive the optical lens to move to the open position to replace the electronic camera module and provide the driver with the field of view in the preset direction; correspondingly, when the optical lens module fails, the vehicle controller can also send a first control instruction to instruct the electronic camera module to turn on, and the electronic camera module provides the driver with the image information in the preset direction; that is, the vehicle controller is electrically connected to the electronic camera module and the optical lens module, and the electronic camera module and the optical lens module are equivalent to being arranged in parallel, so as to independently respond to the control instruction of the vehicle controller. In this way, the reliability of the control system can be improved, and then the driving safety can be improved. Among them, it is also possible to control both the electronic camera module and the optical lens module to enter an on state, that is, the driver can obtain the image signal of the vehicle in a preset direction through the electronic camera module, and at the same time, can obtain the field of view in the preset direction through the optical lens, so that the driver can first obtain the field of view through the traditional optical lens and then slowly adapt to obtaining the field of view through the electronic camera module.

Among them, the optical lens module enters the open state, and the open position of the optical lens can also be driven by the adjustment drive mechanism to drive the optical lens to a plurality of different angle values ​​with the driving surface of the vehicle. For example, when the driving speed of the vehicle is low, on the basis of satisfying the driver's ability to observe the field of view of the vehicle in the preset direction, the optical lens can be adjusted to a smaller angle between the plane where it is located and the driving surface of the vehicle, so as to provide the possibility of reducing wind resistance.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0030] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0031] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0033] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0034] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0035] In an embodiment of the present application, a vehicle is provided, which includes a control system for a vehicle exterior rearview mirror. It should be noted that the vehicle in the embodiment of the present application can be classified according to the vehicle type, and can be a sedan model, an off-road model, a multi-purpose vehicle (MPV) model or other models. The vehicle in the embodiment of the present application can also be a traditional fuel vehicle or a new energy vehicle according to the energy type. In the embodiment of the present application, unless otherwise specified, the vehicle is a pure electric vehicle as an example.

[0036] The electronic exterior mirror control system usually consists of a camera, a controller and a display screen. It does not require traditional glass lenses to obtain a field of view through optical reflection. Since it does not require a large glass lens, the electronic exterior mirror is small and flexible. For example, the electronic exterior mirror can be folded to further reduce the width of the car, making it easier to drive in a narrow space. The appearance of the electronic exterior mirror is also more streamlined, so that the air contact area of ​​the electronic exterior mirror is smaller during driving, thereby reducing wind resistance and increasing the driving range. This is especially important for pure electric vehicles. This requires that the overall shape of the electronic exterior mirror be maintained as much as possible to reflect the advantages of the electronic exterior mirror in reducing wind resistance. In addition, as an electronic device, the electronic exterior mirror is more prone to failure than traditional mechanical mirrors. Not only the camera, but also the display screen and controller in the car, once the electronic exterior mirror fails, the driver will lose the rear view and cannot use the electronic exterior mirror to judge whether there is a car coming from the rear or side, which will affect driving safety. Therefore, how to improve driving safety while retaining the overall appearance of the electronic exterior mirror as much as possible to reduce wind resistance has become an urgent problem to be solved.

[0037] To this end, the present application embodiment provides a control system, referring to Figure 1 to Figure 4 , Figure 6 and Figure 7 The control system includes an electronic camera module 1, an optical lens module 2 and a vehicle controller 3. The electronic camera module 1 is used to collect image signals of the vehicle in a preset direction; the optical lens module 2 includes an optical lens 21 and an adjustment drive mechanism 22; wherein the optical lens 21 is movably connected to a preset position of the vehicle, and the output end of the adjustment drive mechanism 22 is dynamically connected to the optical lens 21; when the optical lens module 2 enters an open state, the adjustment drive mechanism 22 drives the optical lens 21 to move to an open position, so that the driver can observe the preset direction through the optical lens 21 that has moved to the position; when the optical lens module 2 enters a closed state, the adjustment drive mechanism 22 drives the optical lens 21 to move to a closed position, so that the optical lens 21 is combined with the preset position of the vehicle into a whole; the vehicle controller 3 is electrically connected to the electronic camera module 1 and the optical lens module 2, and is used to send a first control instruction to the electronic camera module 1, and / or, to send a second control instruction to the optical lens module 2; wherein the first control instruction is used to instruct the electronic camera module 1 to turn on or off, and the second control instruction is used to instruct the optical lens module 2 to turn on or off.

[0038] The electronic camera module 1 in the embodiment of the present application may be two, and the composition of the two electronic camera modules 1 may be the same. The two electronic camera modules 1 are located on opposite sides in the width direction of the vehicle body, and may be respectively referred to as the left electronic camera module 1 and the right electronic camera module 1. The electronic camera module 1 may include a camera device, a control module and a display device. Specifically, the camera device is used to collect image signals of a preset direction on one side of the vehicle, the control module is used to process the image signals collected by the camera device, and send the corresponding processed image signals to the display device for display, and the display device is used to display the field of view of the camera device in the corresponding direction under the control instructions of the vehicle controller 3 and the control module. Among them, the image signal may be a dynamic image signal, which may be output as a video through the display device; the image signal may also be a static image signal, which may be output as a photo through the display device. The camera device may be a camera, the display device may be a display screen, and the control module may also include a deserializer for parsing the image signals collected by the camera device. Here, the control modules of the electronic camera module 1 on the left and the electronic camera module 1 on the right may be independent of each other and have no communication interaction with each other, or may be able to communicate and interact with each other, without specific limitation.

[0039] In the embodiment of the present application, the control system may further include a central control display screen, which can be used to synchronously receive the image signal of the electronic camera module 1. The central control display screen is connected to the vehicle controller 3, and the user can control the opening of the electronic camera module 1 on the operation interface of the central control display screen. In addition, the opening and closing of the optical lens module 2 can also be operated by the central control display screen, so that the vehicle controller 3 sends instructions to the optical lens module 2. Among them, in order to prevent the information confusion caused by multiple display systems and thus affect driving safety, the adjustment drive mechanism 22 of the optical lens module 2 can be manually opened by the user on the central control display screen, and the manual setting cannot be remembered and needs to be manually opened before each use. In addition, the image signal collected by the camera device can also be displayed by a display device in the electronic camera module 1, such as a display screen of the electronic camera module 1; or the image signal can be transmitted to the central control display screen for display.

[0040] In an embodiment of the present application, for collecting image signals of the vehicle in a preset direction, the preset direction can be understood as the field of view on the side and rear of the vehicle; or it can be understood as the field of view of the image signal in the preset direction that satisfies the driver's ability to see a field of view with a width of at least 2.5 meters from the side and rear of the vehicle to the outer boundary of the vehicle on the driving road; the field of view signal in the preset direction shall be based on the field of view required for driving safety.

[0041] The specific structural form of the adjustment drive mechanism 22 in the embodiment of the present application is not limited, and the output end of the adjustment drive mechanism 22 can be connected to the optical lens 21. Specifically, for example, the adjustment drive mechanism 22 can include a rotating structure that is rotatably connected to a preset position, and the rotating structure can include a motor and a transmission member that is connected to the motor power output shaft, and the transmission member can be used as the output end of the adjustment drive mechanism (22) to be connected to the optical lens 21. The rotation of the power output shaft on the motor can drive the transmission member connected thereto and the optical lens 21 connected to the transmission member to rotate to the open position, or rotate the optical lens 21 to the relative position, so that the optical lens 21 is combined with the preset position of the vehicle into a whole. Alternatively, the adjustment drive mechanism 22 may include a crank-rocker structure, which is connected between a preset position and the optical lens 21. The crank-rocker structure may be composed of at least a crank, a hinged four-bar mechanism of a rocker and a driving member. The driving member drives the crank to rotate, and the optical lens 21 is connected to the rocker, so that the crank drives the rocker and the optical lens 21 connected to the rocker to move to an open position or a closed position; or the adjustment mechanism may be a gear mechanism composed of gears, so that the optical lens 21 connected to the gear mechanism can achieve rotation and position changes at different angles through the combination and transmission of multiple gears, thereby moving the optical lens 21 to an open position or a closed position.

[0042] In the embodiment of the present application, the preset part of the vehicle can be the shell of the electronic exterior rearview mirror on the outside of the vehicle body, or it can be a support structure connected to the vehicle body and extending outside the vehicle body. The support structure can be used as the preset part of the vehicle, and the specific details are not limited. Among them, the preset part can be used to install the electronic camera module 1 and the optical lens 21. The preset part can be a cavity formed with an opening, which is used to set the optical lens module 2 in the cavity, such as, when the optical lens module 2 enters the open state, the optical lens 21 moves to the open position, and the optical lens 21 extends out of the cavity of the preset part; when the optical lens module 2 enters the closed state, the optical lens 21 moves to the closed position, at this time, the optical lens 21 moves to the preset part around the opening to form a whole. Here, the optical lens 21 and the preset part structure are integrated into a whole, which can be understood as the side of the optical lens 21 away from its own reflection surface is flush with the outer surface of the preset part, or when the side of the optical lens 21 away from its own reflection surface and the plane where the preset part is located are both curved surfaces, the two curved surfaces coincide. In this way, when the optical lens module 2 enters the closed state, the optical lens 21 is combined with the preset part into an integral design, so that the preset part is still streamlined, thereby preventing the optical lens 21 from protruding out of the preset part or being recessed into the preset part when the optical lens 21 is retracted, which ultimately affects the overall shape of the preset part.

[0043] With the above design, the electronic camera module 1 can be used to collect image signals of the vehicle in a preset direction, so as to provide the driver with a field of view in the preset direction through the electronic camera module 1. Considering that the electronic camera module 1 has more internal parts and a more complex system, which makes it have a higher failure rate than the traditional glass rearview mirror, an optical lens module 2 is also provided on the basis of the electronic camera module 1. In this way, when the electronic camera module 1 fails, the vehicle controller 3 can send a second control instruction to instruct the optical lens module 2 to turn on, and at the same time, the adjustment drive mechanism 22 can drive the optical lens 21 to move to the open position, and the optical lens 21 provides the driver with a field of view in the preset direction; correspondingly, when the optical lens module 2 fails, the vehicle controller 3 can also send a first control instruction to instruct the electronic camera module 1 to turn on, and the electronic camera module 1 provides the driver with video information in the preset direction; that is, referring to Figure 2 , the vehicle controller 3 is electrically connected to the electronic camera module 1 and the optical lens module 2, and the electronic camera module 1 and the optical lens module 2 are equivalent to being arranged in parallel, so as to independently respond to the control instructions of the vehicle controller 3. In this way, the reliability of the control system can be improved, and then the driving safety can be improved. Among them, it is also possible to control the electronic camera module 1 and the optical lens module 2 to enter the on state, so that the driver can obtain the image signal of the vehicle in the preset direction through the electronic camera module 1, and can also obtain the field of view in the preset direction through the optical lens 21 at the same time, so that the driver can first obtain the field of view through the optical lens 21 and then slowly adapt to obtaining the field of view through the electronic camera module 1, so that while improving driving safety, the adaptability of the control system can also be improved to meet the needs of drivers with different observation field of view habits to obtain the field of view in the preset direction of the vehicle.

[0044] In addition, further, in the application scenario where the electronic camera module 1 functions normally and the electronic camera module 1 alone obtains the image signal in the preset direction, the optical lens module 2 can be put into a closed state, and the adjustment drive mechanism 22 can drive the optical lens 21 to move to the closed position. Accordingly, the adjustment drive mechanism 22 can drive the optical lens 21 to move to form a whole with the preset position, that is, the outer surface of the optical lens 21 is flush with the outer surface of the preset position at the outer periphery of the optical lens 21, and the overall appearance of the electronic exterior rearview mirror can be retained to minimize the damage to the streamlined shape of the electronic exterior rearview mirror, so that when the optical lens module 2 enters the closed state, the control system has the advantage of reducing wind resistance. Among them, when the optical lens module 2 enters the open state, the open position of the optical lens 21 can also be driven by adjusting the driving mechanism 22 to drive the optical lens 21 to present multiple different angles with the vehicle's driving surface. For example, when the vehicle's driving speed is relatively high (such as when the driving speed is greater than 90 km / h), on the basis of satisfying the driver's ability to observe the vehicle's field of vision in a preset direction, the optical lens 21 can be adjusted to a smaller angle between its plane and the vehicle's driving surface to provide the possibility of reducing wind resistance. With such a design, the control system has high safety while also having the advantages of little impact on the overall appearance and reduced wind resistance.

[0045] It should be noted that since the optical lens module 2 adopts the optical lens 21 and the adjustment drive mechanism 22 for driving its movement, these structures are all physical mechanical structures, so that the probability of failure of the optical lens module 2 is extremely low compared with the electronic camera module 1 with a complex system. Therefore, adding an optical lens module 2 on the basis of the electronic camera module 1 can greatly improve the safety of the control system.

[0046] In some embodiments, reference Figure 6 , Figure 7 and Figure 8, the preset part includes the housing 4 of the vehicle's exterior rearview mirror; the housing 4 forms a receiving cavity 41 with an opening, the optical lens module 2 is arranged in the receiving cavity 41, and the optical lens 21 is movably connected to the housing 4 through the adjusting driving mechanism 22; when the optical lens module 2 enters the open state, the optical lens 21 extends out of the housing 4 through the opening; when the optical lens module 2 enters the closed state, the adjusting driving mechanism 22 is used to drive the optical lens 21 to move to fit into the opening as a whole. Here, the shape and size of the housing 4 are not limited. For example, the appearance and size of the housing 4 of the vehicle's exterior rearview mirror can be understood as the housing 4 of the electronic exterior rearview mirror. The housing 4 can be used to provide an installation basis for the electronic camera module 1 and the optical lens module 2, such as, the camera in the electronic camera module 1 can be installed on the outer surface of the housing 4, and the electronic camera module 1 and the optical lens 21 are staggered. Among them, the housing 4 can be fixedly connected to the vehicle body; it can also be movably connected to the vehicle body, such as, the housing 4 itself can also be rotatably connected to the vehicle body through a rotating structure, at this time, that is, the optical lens module 2 and the electronic camera module 1 can move relative to the vehicle body with the housing 4. When the optical lens 21 is in the open position, the optical lens 21 can extend out of the shell 4 through the opening. For example, when the optical lens 21 extends out of the shell 4, the open position of the optical lens 21 corresponds to an angle between the plane where the optical lens 21 is located and the driving surface of the vehicle, so that the driver can observe the preset direction through the optical lens 21 in the open position.

[0047] Reference Figure 6 , Figure 7 and Figure 8, when the optical lens module 2 enters the closed state, the optical lens 21 moves to be integrated with the opening. Among them, the size of the optical lens 21 is adapted to the size of the opening of the shell 4, that is, when the optical lens 21 moves to the opening, the optical lens 21 can fill the opening of the shell 4, so that the optical lens 21 and the opening are integrated. For the optical lens 21 and the opening to be integrated, it can be understood that when the optical lens 21 moves to the closed position, there is no surface difference between the side of the optical lens 21 that is away from its own reflective surface and the outer surface around the opening of the shell 4, that is, it can be understood that the side of the optical lens 21 that is away from its own reflective surface is flush with the outer surface around the opening of the preset position, or when the side of the optical lens 21 that is away from its own reflective surface and the plane of the shell 4 around the opening are both curved surfaces, the two curved surfaces match to form a generally smooth and continuous curved surface, that is, the optical lens 21 and the shell 4 around the opening are combined into a whole. In this way, when the optical lens module 2 enters the closed state, corresponding to when the optical lens 21 is in the closed position, the optical lens 21 is embedded in the opening as a whole, so that the optical lens 21 can be flush with the outer surface around the opening of the shell 4 to meet the gap and surface difference requirements between the optical lens 4 and the shell when it is in the closed position, so that when the optical lens 4 is retracted into the shell 4, the entire shell 4 is still streamlined, thereby minimizing the possibility of the optical lens 21 protruding out of the shell 4 or recessed into the shell 4 when the optical lens 21 is retracted, and it is not easy to affect the overall shape of the shell 4.

[0048] In some embodiments, reference Figure 6 , Figure 7 and Figure 8 The adjusting driving mechanism 22 includes a flip assembly 221, and the flip assembly 221 includes a first driving member 2211 and a rotating shaft 2212; the rotating shaft 2212 is rotationally connected to the shell 4, and the first driving member 2211 is transmission-connected to the rotating shaft 2212, and the rotating axis of the rotating shaft 2212 is parallel to the first plane. The first driving member 2211 is used to drive the rotating shaft 2212 to drive the optical lens 21 to rotate to a preset angle with the first plane, so that the optical lens 21 moves to an open or closed position; wherein the first plane is the plane where the optical lens 21 is located when the optical lens 21 moves to be combined with the outer surface of the shell 4 into a whole.

[0049] Specifically, the first driving member 2211 can be fixed on the inner wall of the housing 4, the rotating shaft 2212 can be connected to the power output shaft of the first driving member 2211 through a transmission member such as a coupling, the rotating shaft 2212 can be hinged with the optical lens 21 through a hinge structure, or the optical lens 21 can be fixed on the cover plate, and the cover plate has a rotating shaft hole adapted to the rotation of the rotating shaft 2212, so as to realize the transmission connection between the rotating shaft 2212 and the first driving member 2211, and then drive the housing 4 connected to it to rotate to a preset angle with the first plane through the rotating shaft 2212. Among them, the first plane can be understood as the plane where the optical lens 21 is located when the optical lens 21 moves to the opening of the housing 4 filled by the optical lens 21, or it can be understood as the plane where the optical lens 21 is located when it is combined into a whole with the outer surface of the housing 4 around the opening. In addition, the first plane can be parallel to the driving surface of the vehicle, or it can have a certain angle with the driving surface of the vehicle. Since the rotation axis of the rotating shaft 2212 is parallel to the first plane, that is, when the rotating shaft 2212 drives the optical lens 21 to rotate, the plane where the optical lens 21 is located can present different preset angles with the first plane. Among them, the preset angle can be 110 degrees, 90 degrees, 80 degrees, etc. Correspondingly, when the optical lens module 2 enters the closed state, the angle between the optical lens 21 and the first plane is 0 degrees, corresponding to the state where the optical lens 21 moves to the opening as a whole, that is, corresponding to the situation where the optical lens 21 moves to the closed position.

[0050] Continue, refer to Figure 6 , Figure 7 and Figure 8The adjustment drive mechanism 22 also includes a support seat 222, which is connected to the inner wall of the shell 4. The support seat 222 has a groove 2225, and at least part of the rotation of the rotating shaft 2212 is adapted to be in the groove 2225, which is used to support the rotating shaft 2212; the optical lens 21 has an outer frame 23, and the outer frame 23 is provided with a mounting hole 231, and the rotating shaft 2212 is rotatably connected to the optical lens 21 through the mounting hole 231. The specific structural form of the support seat 222 is not limited, for example, the support seat 222 may include a support plate 2224 and a first support column 2221, a second support column 2222 and a third support column 2223 erected on the support plate 2224 and spaced apart, the first support column 2221 and the second support column 2222 are both provided with a groove 2225, the groove 2225 on the first support column 2221 and the groove 2225 on the second support column 2222 are both used as mounting nodes of the rotating shaft 2212, and are used as supporting points in contact with the rotating shaft 2212 to support the rotating shaft 2212, and the third support column 2223 is provided with a through hole 2223a, the size of the through hole 2223a is adapted to the cross-sectional size of the rotating shaft 2212. Here, for the sake of convenience, the end of the rotating shaft 2212 close to the first support column 2221 may be referred to as the left end, and the end of the rotating shaft 2212 close to the third support column 2223 may be referred to as the right end. There can be two mounting holes 231 on the outer frame 23, and the two mounting holes 231 are arranged at intervals. The rotating shaft 2212 can pass through the through hole 2223a of the third support column 2223, one of the mounting holes 231 on the outer frame 23, the groove 2225 on the second support column 2222, another mounting hole 231 on the outer frame 23, and the groove 2225 on the first support column 2221 in sequence, and then be installed on the support seat 222. The first support column 2221, the second support column 2222 and the third support column 2223 are used to support the rotating shaft 2212, and the groove 2225 is used to limit the rotating shaft 2212 to move relative to the support seat 222 along the axial direction perpendicular to the rotating shaft 2212. The rotating shaft 2212 is rotatably connected to the mounting hole 231 on the outer frame 23, and is used to drive the outer frame 23 and the optical lens 21 connected to the outer frame 23 to rotate.

[0051] In addition, in order to prevent the rotating shaft 2212 from moving relative to the support seat 222 along the axial direction of the rotating shaft 2212, a limiting structure 24 is provided on the rotating shaft 2212 to prevent the rotating shaft 2212 from moving relative to the support seat 222 along the axial direction of the rotating shaft 2212. Among them, the limiting structure 24 can be a limiting flange arranged on the rotating shaft 2212. For example, the limiting flange can be arranged at the left end of the rotating shaft 2212. The cross-sectional size of the limiting flange is larger than the aperture of the mounting hole 231. The edge of the limiting flange has a deformation portion so that the edge of the limiting flange is deformed to pass through a mounting hole 231 close to the limiting flange and then restore the deformation, so that the edge of the limiting flange is attached to the surrounding side wall of the mounting hole 231, which is used to prevent the rotating shaft 2212 from moving relative to the support seat 222 along the axial direction of the rotating shaft 2212; or the limiting structure 24 can be a retaining spring arranged on the rotating shaft 2212. There can be two retaining springs, which are respectively clamped on the hole walls of the mounting hole 231 of the outer frame 23, and are used to limit the rotating shaft 2212 from moving relative to the support seat 222 along the axial direction of the rotating shaft 2212.

[0052] Among them, the specific form of the first driving member 2211 is not limited, such as, it can be a motor, a cylinder, an oil cylinder, etc. For example, the first driving member 2211 adopts a motor, which is convenient for automatic control, occupies a small space, and is easy to install. Specifically, the first driving member 2211 can be installed on one end of the support seat 222 or the rotating shaft 2212. For example, the right end of the rotating shaft 2212 is fixedly sleeved with a first gear, and the power output shaft of the first driving member 2211 is sleeved with a second gear that meshes with the first gear. In this way, the rotation speed of the rotating shaft 2212 can be controlled by controlling the rotation speed of the first driving member 2211, thereby realizing automatic control of the flip angle of the optical lens 21. Here, the first driving member 2211 can be electrically connected to the vehicle controller 3, and the rotation speed of the first driving member 2211 can be controlled by the vehicle controller 3, or the adjustment drive mechanism 22 can include an adjustment control unit electrically connected to the first driving member 2211 and the vehicle controller 3, and the vehicle controller 3 sends an instruction to the adjustment control unit, and then the adjustment control unit receives the instruction sent by the vehicle controller 3, and then controls the rotation speed of the first driving member 2211 in the adjustment drive mechanism 22 through the adjustment control unit to achieve automatic adjustment of the rotation angle of the optical lens 21. The above structure is simple and easy to implement, and occupies little space inside the housing 4.

[0053] The optical lens 21 in the embodiment of the present application has a peripheral frame 23. Here, the peripheral frame 23 can be a plate-like member with a mounting slot. The size of the mounting slot is adapted to the size of the optical lens 21. The optical lens 21 can be bonded in the mounting slot, or an elastic clamping protrusion is provided on the groove wall of the mounting slot to clamp and fix the optical lens 21 in the mounting slot. The peripheral frame 23 can also be a plate-like member with uniform thickness, and the optical lens 21 is directly bonded to the peripheral frame 23. The design of the peripheral frame 23 is equivalent to adding a reinforcement structure around the optical lens 21 to reduce the possibility of the optical lens 21 breaking.

[0054] It should be noted that, in the case where the optical lens 21 has an outer frame 23, when the optical lens module 2 is closed, the optical lens 21 rotates to be combined with the outer surface of the shell 4 to form a whole. Specifically, the side surface of the outer frame 23 that is away from the reflective surface of the optical lens 21 is combined with the outer surface of the shell 4 at the opening to form a whole, and the surrounding side walls of the outer frame 23 along its own circumferential direction are roughly in contact with the surrounding end surfaces of the opening of the shell 4, that is, the optical lens 21 with the outer frame 23 fills the opening of the shell 4 when the optical lens module 2 is closed, so as to reduce the impact on the original appearance of the shell 4.

[0055] In some embodiments, reference Figure 3 , the adjustment drive mechanism 22 also includes an adjustment control unit, which is used to receive a second control instruction and to control the adjustment drive mechanism 22 according to the second control instruction; wherein the second control instruction at least includes controlling the optical lens 21 to rotate according to the speed information of the current vehicle. Specifically, the adjustment control unit is electrically connected to the first drive member 2211 of the adjustment drive mechanism 22 and the vehicle controller 3 respectively, and the adjustment control unit can be used to receive the second control instruction sent by the vehicle controller 3. The adjustment control unit can respond to the second control instruction of the vehicle controller 3 to make the first drive member 2211 of the adjustment drive mechanism 22 perform corresponding actions, such as controlling the forward or reverse rotation of the first drive member 2211, adjusting the rotation speed of the first drive member 2211, and starting and stopping the first drive member 2211.

[0056] The second control instruction may include controlling the rotation of the optical lens 21 according to the speed information of the current vehicle. For example, when the speed of the current vehicle is relatively high, the angle between the current optical lens 21 and the first plane may be appropriately reduced to reduce wind resistance at the expense of a certain field of view; or the optical lens module 2 may be completely closed to provide a rear field of view of the vehicle through the electronic camera module 1 to minimize wind resistance.

[0057] In some embodiments, the second control instruction further includes controlling the rotation of the optical lens 21 according to the acceleration information of the current vehicle, and / or controlling the rotation of the optical lens 21 according to the steering wheel angle information of the current vehicle. For example, when the acceleration value of the vehicle increases, the angle between the current optical lens 21 and the first plane may be appropriately increased to provide the driver with a better rear visual field of the vehicle; or, when the steering wheel angle of the vehicle increases, considering the higher demand for the rear visual field of the vehicle when turning, the angle between the optical lens 21 and the first plane may be appropriately increased to provide a better field of view.

[0058] Here, refer to Figure 6 , Figure 7 and Figure 8 When the electronic camera module 1 can work normally, the optical lens module 2 can enter the closed state. At this time, the optical lens 21 is in a flipped and retracted state with the outer frame 23, that is, the optical lens 21 is in an unactivated snapped state. The plane where the optical lens 21 is located is combined with the outer surface of the shell 4 into a whole. The overall appearance of the shell 4 is not affected, and the wind resistance is small. When the vehicle controller 3 detects that one or more of the camera, display, controller, and connecting harness in the electronic camera module 1 has a fault and cannot display the image normally to provide the user with an effective rearward field of view, the flipped and snapped optical lens 21 flips to a preset angle between 60° and 90° with the first plane. Among them, when the optical lens 21 is flipped to 60° to 90°, it corresponds to the rearward field of view that the driver can observe corresponding to driving safety.

[0059] In some embodiments, in the open position, the preset angle of the optical lens 21 is adjustable, and the preset angle is negatively correlated with the vehicle speed within the preset vehicle speed range. Among them, for the preset angle of the optical lens 21 to be adjustable, specifically, after the adjustment control unit receives the second control instruction of the vehicle controller 3, the flip assembly 221 in the adjustment drive mechanism 22 can be controlled according to the second control instruction, so that the first driving member 2211 in the flip assembly 221 drives the rotating shaft 2212 to drive the optical lens 21 to rotate different preset angle values, so that the preset angle of the optical lens 21 can be adjusted. In addition, for normal driving safety considerations, the maximum vehicle speed value within the preset vehicle speed range should not exceed 120km / h. For the preset angle within the preset vehicle speed range to be negatively correlated with the vehicle speed, for ease of understanding, for example, the open position may include a first open position and a second open position; accordingly, the preset angle may include a first preset angle corresponding to the first open position and a second preset angle corresponding to the second open position. Specifically, when the vehicle is in a first preset speed range, the optical lens 21 is in a first open position, and the plane where the optical lens 21 is located has a first preset angle with the first plane; when the vehicle is in a second preset speed range, the optical lens 21 is in a second open position, and the plane where the optical lens 21 is located has a second preset angle with the first plane; wherein the speed value within the first preset speed range is smaller than the speed value within the second preset speed range, and the first preset angle is greater than the second preset angle, that is, when the vehicle speed increases, the preset angle of the adjustable optical lens 21 becomes smaller.

[0060] In the above example, the first preset speed range can be 0-90km / h, and the second preset speed range is 91-120km / h. Correspondingly, the first preset angle is greater than the second preset angle. Considering that the wind resistance caused by the optical lens 21 will significantly increase the impact on the vehicle's energy consumption when the vehicle speed is high, accordingly, the larger the preset angle of the optical lens 21, the greater the wind resistance generated. Therefore, when the vehicle is in the second preset speed range with a higher speed, the second preset angle of the optical lens 21 can be made smaller than the first preset angle, that is, the preset angle of the optical lens 21 is reduced relative to the case where the vehicle speed is low, so as to reduce wind resistance.

[0061] Here, it should be noted that, although the second preset angle is smaller than the first preset angle, the second preset angle cannot be too small. For example, when the second preset angle is less than 60 degrees, the driver's observable field of view will become too narrow, so that driving safety cannot be guaranteed. Therefore, the second preset angle and the first preset angle should be within the preset angle range of driving safety, that is, the corresponding rearward field of view observable by the driver under driving safety. Here, the preset angle range can be between 60° and 90°, that is, although the second preset angle is smaller than the first preset angle, the second preset angle still falls between the preset angle range. For example, when the first preset angle is 80° to 90°, the second preset angle can be 65° to 75°; when the first preset angle is 85 degrees, the second preset angle is 80 degrees. With such a design, when the vehicle speed increases, the preset angle between the plane where the optical lens 21 is located and the first plane can be appropriately reduced to better balance the wind resistance and the field of view within the preset angle range of driving safety.

[0062] In some embodiments, reference Figure 6 , Figure 7 and Figure 8 , the adjustment drive mechanism 22 also includes a lifting component 223 and a horizontal adjustment component 224; the lifting component 223 includes a second driving member 2231 and a transmission structure 2232, the second driving member 2231 is connected to the transmission structure 2232 in transmission connection, the transmission structure 2232 is connected between the support seat 222 and the shell 4, the second driving member 2231 is used to drive the transmission structure 2232 and the support seat 222 connected to the transmission structure 2232 to move along the first direction, so that the support seat 222 drives the optical lens 21 to move along the first direction; the horizontal adjustment component 224 is arranged between the support seat 222 and the shell 4, and is used to drive the support seat 222 and the optical lens 21 connected to the support seat 222 to move along the second direction; wherein the first direction is parallel to the height direction of the vehicle body, and the second direction is parallel to the axial direction of the rotating shaft 2212. In some possible implementation schemes, the second direction can be parallel to the width direction of the vehicle body, and the second direction can be simply understood as a direction parallel to the extension direction extending out of the vehicle body outer shell 4.

[0063] Among them, the second drive member 2231 can be a motor that is convenient for automatic control, and the motor can be arranged on the support seat 222. The transmission structure 2232 can include a screw and a screw sleeve that cooperates with the screw thread. Specifically, the screw can be connected to the power output shaft of the second drive member 2231 to drive the screw to rotate along a plane perpendicular to the screw axis. The screw sleeve can be vertically fixedly connected to the bottom of the support seat 222 to drive the screw sleeve to move in the first direction through the screw, so that the support seat 222 drives the optical lens 21 connected thereto to move in the first direction; the transmission structure 2232 can also include a telescopic shaft, which is connected to the power output shaft of the second drive member 2231, and the axial direction of the telescopic shaft is parallel to the first direction. The end of the telescopic shaft away from the second drive member 2231 is connected to the support seat 222, which is used to drive the support seat 222 to move in the first direction. In this way, through the cooperation of the lifting assembly 223 and the flip assembly 221, the optical lens 21 can be lifted relative to the vehicle body and flipped at the same time.

[0064] In some embodiments, in the open position, the lifting assembly 223 is used to drive the optical lens 21 to move to a preset height, wherein the preset angle is negatively correlated with the preset height. Among them, the preset height is the distance that the optical lens 21 moves out of the housing 4 along the first direction, that is, when the optical lens 21 is flipped to a smaller preset angle with the first plane, for example, when the preset angle between the optical lens 21 and the first plane is reduced from 70° to 60°, the driver's observable field of view becomes narrower; the lifting assembly 223 can drive the optical lens 21 to rise along the first direction to increase the distance that the optical lens 21 extends out of the housing 4 in the first direction, so as to expand the observable field of view of the optical lens 21 and compensate the driver for the field of view sacrificed after the angle of the optical lens 21 becomes smaller. Specifically, the vehicle's driving speed may increase, so that the preset angle between the optical lens 21 and the first plane becomes smaller. For example, when the vehicle is in a second preset speed range, the flip assembly 211 is used to drive the plane where the optical lens 21 is located to have a second preset angle with the first plane, and the lifting assembly 223 is used to drive the optical lens 21 to move to a preset height along the first direction. Taking into account that when the vehicle increases from a first preset speed range with a lower speed to a second preset speed range with a higher speed, the reduction in the preset angle of the optical lens 21 will cause the driver's observable field of view to narrow, therefore, when the optical lens 21 is at the second preset angle, the lifting component 223 in the adjustment drive mechanism 22 can be activated to drive the optical lens 21 to extend out of the shell 4 to a preset height along the first direction (i.e., the optical lens 21 is lifted while the flip angle of the optical lens 21 is adjusted). In this way, the rear field of view of the vehicle can be expanded by lifting the optical lens 21, which is equivalent to providing a certain visual field supplement for the narrowing of the field of view caused by reducing the preset angle, so that the optical lens 21 can meet the driver's better visual field requirements when the vehicle is in the second preset range as much as possible.

[0065] Furthermore, by adding a horizontal adjustment component 224, while realizing the lifting and flipping of the optical lens 21 relative to the vehicle body, the movement of the optical lens 21 relative to the housing 4 along the second direction can also be realized, so that the optical lens 21 can be flexibly adjusted in multiple directions, so as to control the movement of the optical lens 21 to the open position. Among them, the horizontal adjustment component 224 may include a guide groove extending along the second direction provided on the housing 4 and a guide block provided at the bottom end of the support seat 222, and the support seat 222 is driven to move relative to the housing 4 along the second direction through a driving member; or the horizontal adjustment component 224 includes a telescopic cylinder, the telescopic cylinder has a telescopic shaft, the axial direction of the telescopic shaft is parallel to the second direction, and the free end of the telescopic shaft is connected to the support seat 222 to drive the support seat 222 to move along the second direction, thereby causing the support seat 222 to drive the optical lens 21 connected thereto to move along the second direction.

[0066] In some other embodiments, the horizontal adjustment assembly 224 includes a third driving member 2241 and a rotating assembly, and the rotating assembly includes a first meshing gear and a second meshing gear, the first meshing gear is fixed on the support rod 2232a, the second meshing gear is connected to the third driving member 2241 by transmission, and the second meshing gear is meshed with the first meshing gear for driving the support rod 2232a and the support seat 222 fixedly connected to the support rod 2232a to rotate around the axis of the support rod 2232a, so that the support seat 222 drives the optical lens 21 to rotate around the axis of the support rod 2232a. Specifically, the first meshing gear can be sleeved on one end of the support rod 2232a away from the support seat 222, the second meshing gear is sleeved on the power output shaft of the third driving member 2241, and the rotation axis of the second meshing gear is parallel to the axis of the support rod 2232a. Among them, the axis direction of the support rod 2232a can be parallel to the first direction. The above design has a simple and compact structure, and can further enhance the multi-directional adjustment of the optical lens 21, thereby satisfying the driver's demand for a better visual field.

[0067] Continue, exemplarily, with reference to Figure 6 , Figure 7 and Figure 8 The transmission structure 2232 includes a support rod 2232a and a gear, the support rod 2232a is connected to the bottom of the support seat 222, a rack is vertically fixed on the support rod 2232a, the second driving member 2231 is connected to the gear transmission, the gear and the rack are meshed for transmission, and are used to drive the support rod 2232a and the support seat 222 fixedly connected to the support rod 2232a to move along the first direction; the horizontal adjustment component 224 includes a third driving member 2241 and a sliding structure, the sliding structure includes a slide groove arranged on the inner wall of the shell 4, and the extension direction of the slide groove is parallel to the second direction; the end of the support rod 2232a away from the support seat 222 is slidably matched with the slide groove, and the third driving member 2241 is connected to the support rod 2232a for driving the support rod 2232a to slide in the second direction, so that the support rod 2232a drives the support seat 222 and the optical lens 21 connected to the support seat 222 to move in the second direction. The second driving member 2231 and the third driving member 2241 may also be clamped in the mounting groove 42 of the bottom wall of the shell 4 to make the entire adjustment driving mechanism 22 more compact.

[0068] It should be noted that in order to improve the compactness of the control system, the adjustment drive mechanism 22 is arranged in the accommodating cavity of the shell 4. In order to reduce the possibility of interference and collision between the horizontal adjustment component 224 or other components in the adjustment drive mechanism 22 and the shell 4 when the optical lens 21 moves along the second direction, therefore, in the embodiment of the present application, the movement range of the optical lens 21 along the second direction is relatively small, which is equivalent to fine-tuning the movement of the optical lens 21 along the second direction.

[0069] In some embodiments, reference Figure 4 and Fig. 9 , the control system also includes an automatic adjustment module for responding to the second control instruction, and adjusting the optical lens 21 to the open position by controlling the adjustment drive mechanism 22 according to the eye position of the driver. Among them, the automatic adjustment module at least includes a positioning processing unit, the positioning processing unit is used to obtain the reference point of the driver's eyes and the center position of the optical lens 21, and determine the open position according to the eye position, the center position and the target reflection landing point of the optical lens 21; wherein, the line connecting the center position and the reference point forms the center line of the driver's field of vision, and the line connecting the center position and the target reflection landing point forms the center line of the reflection field of vision. In the open position, the plane where the optical lens 21 is located is perpendicular to the angular bisector of the center line of the driver's field of vision and the center line of the reflection field of vision. Here, the center position of the optical lens 21 can be understood as the center point position of the effective display area of ​​the optical lens 21, such as, when the effective display area of ​​the optical lens 21 is a rectangle, the center position is the intersection of the two diagonals of the rectangle.

[0070] For the determination of the target reflection landing point of the optical lens 21, for example, according to the size of the optical lens 21, the distance between the target reflection landing point and the reference point can be 8-15m, and the distance between the target reflection landing point and the outer boundary of the vehicle body can be 1m-1.5m. For example, in the embodiment of the present application, the distance between the selected target reflection landing point and the reference point is 8m, and the distance between the target reflection landing point and the outer boundary of the vehicle body is 1m as an example to meet the driver's field of vision comfort. Considering that the height, weight, sitting posture, etc. of the driver cannot be exactly the same, when the electronic camera module 1 fails during high-speed driving of the user, the optical lens module 2 is turned on at this time, and the field of vision displayed by the optical lens 21 at this time may not be the driver's effective observation field of vision. The automatic adjustment module can also include a driver monitoring system (Driver Monitor System, DMS) used in conjunction with the positioning processing unit. Here, the driver monitoring system can be used for functions such as driver line of sight detection, face recognition, and expression recognition. For example, the driver monitoring system detects the position of the driver's eyes, and after the positioning processing unit processes the position information, it inputs the information into the vehicle controller 3. The vehicle controller 3 automatically adjusts the relative position of the optical lens 21 and the reference point of the driver's eyes by controlling the flip component 221, the lifting component 223 and the horizontal adjustment component 224 of the adjustment drive mechanism 22, so as to ensure that the driver can effectively observe the rear road conditions without excessive manual operation of the optical lens module 2, thereby ensuring driving safety.

[0071] In some embodiments, reference Figure 1 and Figure 5The electronic camera module 1 includes a first electronic camera module 1 and a second electronic camera module 1 located on opposite sides of the vehicle; the first electronic camera module 1 includes a first camera module, a first control module and a first display module, and the first control module is connected to the first camera module and the first display module; the second electronic camera module 1 includes a second camera module, a second control module and a second display module, and the second control module is connected to the second camera module and the second display module; wherein the first control module is also connected to the second camera module and the second display module, and the first control module is used to process the image signal collected by the second camera module when the second control module fails, and send the processed image signal to the second display module for display.

[0072] Among them, for the convenience of explanation, the first electronic camera module 1 can be called the electronic camera module 1 of the electronic exterior rearview mirror on the left side of the vehicle body, and the second electronic camera module 1 can be called the electronic camera module 1 of the electronic exterior rearview mirror on the right side of the vehicle body. The first camera module is used to collect video image data of the driving environment on the left side of the vehicle to generate an image signal in a preset direction. The first control module in the first control module is used to process the image signal collected by the first camera module, and send the corresponding processed image signal to the first display module for display. The first display module is used to display the rear view corresponding to the first camera module under the drive of the first control module.

[0073] Furthermore, the first control module in the first control module is also connected to the second camera module and the second display module on the right side of the vehicle, and the second camera module and the second display module are respectively connected to the second control module. Specifically, the second camera module and the second display module are respectively connected to the second control module in the second control module. The first control module is used to process the image signal collected by the second camera module when a failure occurs in the second camera module, and send the processed image signal to the second display module for display. Among them, the failure of the second control module includes the failure of the second control module or other components in the second control module, such as the failure of the second display module; the first camera module and the second camera module can both be cameras, and the first display module and the second display module are display screens.

[0074] The above design is such that, in addition to being connected to the first camera module and the first display module on the left side of the vehicle, the first control module is also connected to the second camera module and the second display module on the right side of the vehicle. Therefore, when the second control module fails, the first control module can process the image signal collected by the second camera module, and then forward it to the second display module for display, thereby effectively avoiding the situation where the driver loses the rearward field of view on one side of the second camera module when the second control module fails, so as to improve driving safety. Furthermore, the second control module in the second control module is also connected to the first camera module and the first display module, and the second control module is used to process the image signal collected by the first camera module when the first electronic camera module 1 on the left side fails, and send the corresponding processed image signal to the first display module for display. In this way, the reliability of the electronic camera module 1 can be further improved, which is equivalent to greatly reducing the failure rate of the electronic camera module 1. In the embodiment of the present application, since an optical lens module 2 is also provided, even if the electronic camera module 1 with improved reliability fails, the optical lens 21 of the optical lens module 2 can continue to obtain the rear view of the vehicle, which undoubtedly improves the reliability of the control system to a greater extent.

[0075] In some embodiments, reference Figure 5 , the first control module also includes a first deserializer, a second deserializer and a first power supply module, the first deserializer is connected to the first camera module and the first control module, and the first deserializer is used to parse the image signal collected by the first camera module. The second deserializer is connected to the second camera module and the first control module, and the second deserializer is used to parse the image signal collected by the second camera module when the second control module fails, and the first power supply module is used to power the first control module. Further, the second control module also includes a third deserializer and a fourth deserializer. Among them, the third deserializer is connected to the second camera module and the second control module, and the third deserializer is used to parse the image signal collected by the second camera module. The fourth deserializer is connected to the first camera module and the second control module, and the fourth deserializer is used to parse the image signal collected by the first camera module when the first control module on the left fails, and the second power supply module is used to power the second control module. The first bus transceiver and the second bus transceiver are used to transmit information between the first control module and the second control module. In addition, the first control module and the second control module confirm each other's working status through the interconnected CAN_H and CAN_L.
