Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a lift-type vehicle passenger monitoring system and its control method. Background Technology

[0002] With the advancement of global technology, new technologies, new business models, and new formats are emerging in the automotive industry. The trend of the automotive industry towards electrification, intelligence, and sharing is already very clear. As one of the most important systems for improving comfort in smart cockpits, the On-Site Management System (OMS) is being adopted by electric vehicles year by year. However, the privacy and security issues that arise from this are gradually being brought to the forefront. Different OEMs have different solutions, which can be roughly divided into the following two types: ① adding a baffle to physically block the camera when it is not in use; ② not considering privacy and security.

[0003] For example, patent CN103707813A discloses a car rearview mirror, including a base, a mirror support rod, and a mirror body. One end of the mirror support rod is connected to a bushing on the base via a rotating shaft, and the other end of the mirror support rod is fixedly connected to the mirror body. An eye recognition device is provided below the mirror body and is fixedly connected to the mirror body. A monitoring camera is provided on one side of the mirror body and is fixedly connected to the mirror body. Patent CN204870749U discloses a car rearview mirror, including a rearview mirror body; a mobile communication device is provided inside the rearview mirror body, and the touch screen of the mobile communication device is placed on the mirror surface of the rearview mirror body. A rotating camera is provided on the top of the rearview mirror body.

[0004] Most of the existing surveillance cameras installed on the rearview mirrors are exposed, which does not fully consider the privacy and security of passengers and cannot meet the needs of current and future vehicle designs. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a lift-type vehicle passenger monitoring system and its control method, which is convenient and quick to operate, balances passenger comfort with privacy protection, and enhances the customer experience.

[0006] To achieve the above objectives, the technical solution adopted by the present invention to solve its technical problem is as follows: the lifting vehicle passenger monitoring system includes a slide rail system built into the rearview mirror cover and fixedly connected to the vehicle body, and a camera assembly that can extend or retract from the rearview mirror cover is slidably connected to the slide rail system.

[0007] The slide rail system includes a box-shaped slide rail body, a guide component is provided inside the slide rail body, a slider is slidably connected to the guide component, and the slider is fixedly connected to the camera assembly.

[0008] The guide assembly includes a plurality of guide pins fixed along the length of the slide rail body, and the slider is slidably connected to the plurality of guide pins.

[0009] Each of the guide pins is fitted with a spring, which abuts against one end of the slide rail body and the slider.

[0010] The slider is equipped with a locking and unlocking mechanism, and the slide rail body is provided with a locking and unlocking groove that cooperates with the locking and unlocking mechanism to achieve the positioning and locking of the slider.

[0011] The locking and unlocking mechanism includes an L-shaped rod rotatably connected to the slider. The locking and unlocking groove includes a straight groove section and an annular groove section disposed at the bottom of the slide rail body. The straight groove section is arranged along the length direction of the slide rail body, and the annular groove section is provided with a slot that engages with the L-shaped rod.

[0012] A locking protrusion is provided in the middle of the annular groove section, and a downward recessed slot is provided at the upper center of the locking protrusion.

[0013] The angle between the slide rail body and the horizontal plane is 50~60°.

[0014] One end of the slide rail body is provided with an integral fixed base, which is fixedly connected to the vehicle body through an assembly mounting bracket.

[0015] The camera assembly includes a fixed bracket fixedly connected to the slider and a camera decorative cover connected thereto. The camera system is installed in the cavity formed by the fixed bracket and the camera decorative cover.

[0016] The camera decorative cover is provided with multiple fixed threaded posts I that are fixedly connected to the camera system and multiple fixed threaded posts II that are fixedly connected to the fixed bracket.

[0017] The camera decorative cover includes a front decorative cover and a rear decorative cover that are snapped together. The front end of the front decorative cover is provided with a receiving hole that mates with the camera of the camera system.

[0018] The upper end of the camera decorative cover is provided with an opening, and the fixed bracket includes a bracket body installed at the opening end of the camera decorative cover. The bracket body is provided with a connecting plate fixedly connected to the slider and a hollow structure that is inserted and engaged with one end of the slide rail system.

[0019] The connecting plate is configured as a U-shaped plate that is slidably connected to the slide rail body. A spring is provided on the inner side of the U-shaped plate. A micro switch is provided on one side of the lower end of the slide rail body. The micro switch is connected to the camera system through the vehicle controller to control the opening and closing of the camera system.

[0020] A control method for the aforementioned lift-type vehicle passenger monitoring system includes a control process for the lowering and raising of the camera assembly.

[0021] Control process for the camera assembly lowering action: Manually operate the camera assembly to lower it and extend the inner rearview mirror cover, triggering the micro switch on one side of the slide rail system, and the vehicle controller controls the camera system to turn on.

[0022] Control process for the camera assembly lifting action: Manually lift the camera assembly to retract it into the inner rearview mirror cover, turn off the micro switch on one side of the slide rail system, and the vehicle controller controls the camera system to shut down.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention provides a sliding rail system within the rearview mirror cover, on which a camera assembly is slidably connected. The camera assembly can be controlled to slide up and down along the sliding rail system as needed, allowing it to extend or retract from the rearview mirror cover. This balances passenger comfort with privacy protection, enhancing the customer experience.

[0025] 2. This invention provides a locking / unlocking mechanism and a corresponding locking / unlocking groove within the slide rail system. The locking / unlocking mechanism slides within the groove. As the camera assembly slides downwards along the guide post with the slider, the locking / unlocking mechanism slides sequentially along the annular groove and the straight groove until it reaches the end of the straight groove, thus achieving downward sliding extension and positioning of the camera assembly. Conversely, as the camera assembly slides upwards along the guide post with the slider, the locking / unlocking mechanism slides sequentially along the straight groove and the annular groove until it enters the slot of the annular groove, thus achieving upward sliding retraction and positioning of the camera assembly. This makes the lifting and lowering operation of the camera assembly more convenient and faster.

[0026] 3. This invention provides a spring clip on the inner side of the U-shaped connecting plate of the fixed bracket of the camera assembly, and a micro switch is installed on the lower side of the slide rail system. When the camera assembly slides along the slide rail system to the lowest point, that is, after the camera assembly extends out of the rearview mirror cover, the spring clip abuts against and triggers the micro switch, transmitting a signal to the vehicle controller. This causes the vehicle controller to control the camera system to start monitoring. Similarly, when the camera assembly retracts into the rearview mirror cover, the camera system shuts down, ensuring the normal operation of the camera system. Attached Figure Description

[0042] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0044] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0045] In existing technologies, most of the surveillance cameras in passenger monitoring systems (OMS) mounted on the rearview mirror are exposed, failing to adequately consider passenger privacy and security, and thus not meeting the needs of current and future vehicle designs. Therefore, based on the above-mentioned technical problems in the prior art, this invention provides a lift-up vehicle passenger monitoring system, the specific structure of which is as follows: Figures 1-4 As shown, this lift-type vehicle passenger monitoring system includes a slide rail system 2 built into the rearview mirror cover 1 and fixedly connected to the vehicle body. A camera assembly 3, which can extend or retract from the rearview mirror cover 1, is slidably connected to the slide rail system 2. The slide rail system 2 also includes a locking and unlocking device for locking and positioning the camera assembly 3. The camera assembly 3 can be controlled to slide up and down along the slide rail system 2 as needed. When not in use, the camera assembly 3 retracts into the rearview mirror cover 1; when in use, the camera assembly 3 extends out of the rearview mirror cover 1. The locking and unlocking device can lock and position the camera assembly 3, balancing passenger comfort and privacy, thus improving the customer's user experience.

[0046] Specifically, such as Figure 5 and Figure 6 As shown, the slide rail system 2 includes a box-shaped slide rail body 21. The slide rail body 21 has a rectangular box structure, including four mutually perpendicular side walls and a base plate connected to the four side walls. A guide assembly is provided inside the slide rail body 21. A slider 23 is slidably connected to the guide assembly. The slider 23 is fixedly connected to the camera assembly 3. The slider 23 slides along the guide assembly, which can drive the camera assembly 3 to slide along the guide assembly, allowing the camera assembly 3 to extend or retract into the rearview mirror cover 1.

[0047] Specifically, the angle between the slide rail body 21 and the horizontal plane is 50~60°, which allows the camera assembly 3 to tilt out or move upward, and cooperate with the through hole and profile at the lower end of the rearview mirror cover 1, thereby reducing the Z-axis height of the entire passenger monitoring system, making more reasonable use of the space inside the rearview mirror cover 1, and ensuring the overall aesthetics of the rearview mirror cover 1.

[0048] The guiding component includes multiple guide pins 22 fixed along the length of the slide rail body 21. Specifically, multiple guide pins 22 are installed between two relatively far opposite side walls. Sliding sliders 23 are slidably connected to the multiple guide pins 22, ensuring that the sliders 23 drive the camera assembly 3 to slide stably along the length of the slide rail body 21 without tilting, thus ensuring the smooth extension or retraction of the rearview mirror cover 1 of the camera assembly 3.

[0049] Furthermore, to enable faster extension of the camera assembly 3 and more stable retraction and locking, a spring 24 is fitted onto each guide post 22. The spring 24 is connected between one end of the slide rail body 21 and the slider 23. When the slider 23 slides upward along the guide post 22 and is positioned by the locking and unlocking device, the spring 24 is compressed. The spring 24 exerts a downward elastic force on the slider 23, which can stably lock the locking and unlocking device and make the retraction and locking of the camera assembly 3 more stable. When the slider 23 slides downward along the guide post 22, the compressed spring 24 exerts a downward elastic force on the slider 23, pushing the slider 23 to move downward quickly back to its position, so that the camera assembly 3 can extend quickly.

[0050] Specifically, the locking and unlocking device includes a locking and unlocking mechanism 25 installed on the slider 23 and a locking and unlocking groove 26 provided in the slide rail body 21. The locking and unlocking groove 26 is provided on the bottom plate of the slide rail body 21. The locking and unlocking mechanism 25 cooperates with the locking and unlocking groove 26 to achieve the positioning and locking of the slider 23.

[0051] Specifically, the locking and unlocking mechanism 25 includes an L-shaped rod rotatably connected to the slider 23. The locking and unlocking groove 26 includes a straight groove section 261 and an annular groove section disposed at the bottom of the slide rail body 21. The straight groove section 261 is arranged along the length direction of the slide rail body 21. The annular groove section is provided with a slot 265 that engages with the L-shaped rod. A locking protrusion 264 is provided in the middle of the annular groove section. A downwardly recessed slot 265 is provided at the upper center of the locking protrusion 264. Moreover, the outer edge shape of the annular groove section is the same as the shape of the locking protrusion 264. It includes a rising engaging section 262 and a rising disengaging section 263 disposed along the extending direction of the slot 265. Moreover, the rising insertion section 262 and the rising exit section 263 have the same function and can be used interchangeably. That is, when the L-shaped rod is rising and being inserted, it can enter the rising insertion section 262 along the straight groove section 261, or it can enter the rising exit section 263 from the straight groove section 261 and then be inserted into the slot 265 to lock the L-shaped rod and the slider 23. When the slider 23 is moving downward, it can exit from the rising insertion section 262 or the rising exit section 263 to the straight groove section 261.

[0052] The working principle of the above-mentioned locking and unlocking device is as follows: When the camera assembly 3 is not in use, manually push the camera assembly 3 upward. The camera assembly 3 slides upward along the guide slide post 22 with the slider 23, causing the camera assembly 3 to gradually retract into the inner rearview mirror cover 1. At the same time, the end of the L-shaped rod slides counterclockwise along the straight groove section 261 to the rising engagement section 262 of the annular groove section or clockwise to the rising exit section 263 of the annular groove section and then engages in the slot 265. At the same time, the spring 24 is compressed, and the spring 24 gives the slider 23 a downward elastic force and the L-shaped rod a downward pulling force, so that the L-shaped rod is stably engaged in the slot 265, realizing the stable locking and positioning of the L-shaped rod, the slider 23, and the camera assembly 3; when the camera is in use... When the head assembly 3 is in position, manually push the camera assembly 3 upward to move it downward. Under the thrust of the spring 24, the camera assembly 3 slides downward along the guide slide post 22 with the slider 23, causing the camera assembly 3 to gradually extend out of the inner rearview mirror cover 1. At the same time, the end of the L-shaped rod slides counterclockwise along the rising exit section 263 of the annular groove or clockwise along the rising locking section 262 of the annular groove to the straight groove section 261, until the end of the L-shaped rod slides to the very end of the straight groove section 261, at which point the camera assembly 3 is fully extended out of the inner rearview mirror cover 1. At this time, the spring 24 is still in a compressed state, and the spring 24 gives the slider 23 a certain thrust, so that the camera assembly 3 can stably extend out of the inner rearview mirror cover 1.

[0053] Specifically, such as Figure 13 As shown, one end of the slide rail body 21 is provided with an integral fixed base 27. The fixed base 27 is provided with multiple fixing holes I 271 and multiple positioning holes I 272. The fixed base 27 is connected to the assembly mounting bracket 4, which is fixedly connected to the vehicle body. The assembly mounting bracket 4 is a U-shaped stamped part with reinforcing ribs at the corners. Multiple fixing holes II 41 and multiple positioning holes II 42 connected to the vehicle body are provided on both ends of the U-shaped stamped part. A strip-shaped snap-fit ​​hole 43 is provided on one side of the U-shaped stamped part. An elastic snap-fit ​​foot 11 that snaps into the corresponding strip-shaped snap-fit ​​hole 43 is provided on the inner wall of the rearview mirror cover 1. A threaded hole 44 corresponding to the corresponding fixing hole I 271 is provided on the other side of the U-shaped stamped part. The fixed base 27 of the slide rail body 21 can be fixedly connected to the U-shaped stamped part by bolts. The assembly mounting bracket 4 is also provided with a wire harness fixing hole 45 to facilitate the installation of the connection wire harness connected to the camera system. The assembly mounting bracket 4 provides mounting points for the slide rail body 21, the interior rearview mirror cover 1, and the vehicle body, improving the stability of the entire lift-type vehicle passenger monitoring system installation.

[0054] Specifically, the camera assembly 3 includes a fixed bracket 31 fixedly connected to the slider 23 and a camera decorative cover 32 connected thereto. The camera system 33 is installed in the cavity formed by the fixed bracket 31 and the camera decorative cover 32.

[0055] like Figure 7 and Figure 8 As shown, the camera system 33 includes a camera body 331, and a camera housing 332 is provided on the outside of the camera body 331. A wire harness connector 333 connected to the camera body 331 is fixed at the rear of the camera housing 332. Multiple fixing lugs 334 connected to the camera decorative cover 32 are provided on the camera housing 332, which facilitates the disassembly and installation of the camera system 33. After the camera system 33 is installed in the camera decorative cover 32, the lens of the camera body 331 is tilted downwards to ensure the required monitoring angle.

[0056] like Figure 9 and Figure 10 As shown, the camera decorative cover 32 contains multiple threaded posts I 321 fixedly connected to the camera system 33 and multiple threaded posts II 322 fixedly connected to the mounting bracket 31. The camera decorative cover 32 includes a front decorative cover 323 and a rear decorative cover 325 324 that are snap-fitted together. The front decorative cover 323 contains multiple threaded posts I 321, which are opposite to multiple mounting lugs 334 on the camera housing 332 and fixedly connected by bolts. The rear sides of both the front and rear decorative covers 323 and 325 324 contain multiple threaded posts II 322, which are fixedly connected to the mounting bracket 31, ensuring a secure connection between the camera decorative cover 32 and the mounting bracket 31 and providing reliable protection for the camera system 33. Furthermore, the front of the front decorative cover 323 has a receiving hole that mates with the camera lens of the camera system 33, preventing obstruction of the camera. Furthermore, since the angle between the slide rail body 21 and the horizontal plane is 50~60°, the front and rear surfaces of the camera decorative cover 32 are also arranged at an angle, ensuring that the camera assembly 3 can smoothly extend or retract the rearview mirror cover 1.

[0057] like Figure 11 and Figure 12As shown, the upper end of the camera decorative cover 32 has an opening. The fixing bracket 31 includes a bracket body 311 installed at the opening end of the camera decorative cover 32. The bracket body 311 is snapped into the opening end of the camera decorative cover 32. The bracket body 311 has multiple mounting holes 312 connected to corresponding fixing threaded posts II 322. The bracket body 311 also has an integrally formed connecting plate 313. The connection between the connecting plate 313 and the bracket body 311 has a reinforcing rib. The connecting plate 313 is a U-shaped plate. After the connecting plate 313 is snapped into the slider 23, it is fixedly connected to the slider 23 by multiple bolt assemblies. In order to further ensure the stability of the sliding of the camera assembly 3, the connecting plate 313 is slidably connected to the slide rail body 21. The two sides of the connecting plate 313 cover the two sides of the slide rail body 21. The bracket body 311 also has a hollow structure 314 that is inserted into one end of the slide rail system 2, providing a sliding guide for the sliding of the camera assembly 3.

[0058] A spring is provided on the inner side of the connecting plate 313, and a micro switch is provided on one side of the lower end of the slide rail body 21. The micro switch is connected to the camera system 33 through the vehicle controller to control the opening and closing of the camera system 33. When the camera assembly 3 slides along the slide rail system 2 to the bottom, that is, after the camera assembly 3 extends out of the rearview mirror cover 1, the spring abuts against and triggers the micro switch, transmitting a signal to the vehicle controller, causing the vehicle controller to control the camera system 33 to start monitoring. Similarly, when the camera assembly 3 retracts into the rearview mirror cover 1, the camera system 33 shuts down, ensuring the normal operation of the camera system 33. Of course, a micro switch can also be installed on the inner wall of the bottom end of the slide rail body 21. When the camera assembly 3 slides along the slide rail system 2 to the bottom, the slider 23 abuts against the micro switch, which can also trigger the micro switch, and the vehicle controller controls the camera system 33 to start monitoring. When the camera assembly 3 slides upward along the slide rail system 2, the slider 23 disengages from the micro switch, de-energizing it, and the vehicle controller controls the camera system 33 to shut down. Of course, this invention also protects other types of inductive switches, including photoelectric switches, limit switches, etc. It also protects the technical solutions of the camera system 33 installed in other positions on the slide rail system 2, which sense the position of the camera assembly 3 through the inductive switch and transmit the signal to the vehicle controller, and control the opening and closing principle of the camera system 33 through the vehicle controller. All of these are within the protection scope of this invention.

[0059] The control method for the aforementioned lift-type vehicle passenger monitoring system includes the control process for the lowering and raising movements of the camera assembly 3.

[0060] 1) Control process of camera assembly 3 lowering action: Manually operate camera assembly 3 to lower it and extend the inner rearview mirror cover 1, triggering the micro switch on one side of the slide rail system 2, and the vehicle controller controls the camera system 33 to open.

[0061] The specific control process is as follows: After manually pushing the camera assembly 3 upward, the end of the locking and unlocking mechanism 25 disengages from the slot 265. Under the pushing force of the spring 24, the camera assembly 3 slides downward along the guide slide post 22 with the slider 23, causing the camera assembly 3 to gradually extend out of the interior rearview mirror cover 1. At the same time, the end of the locking and unlocking mechanism 25 slides counterclockwise along the rising exit section 263 of the annular groove or clockwise along the rising locking section 262 of the annular groove to the straight groove section 261, until the end of the L-shaped rod slides to the end of the straight groove section 261, at which point the camera assembly 3 is fully extended out of the interior rearview mirror cover 1. At this time, the spring 24 is still in a compressed state, and the spring 24 gives the slider 23 a certain pushing force, so that the camera assembly 3 is stably extended out of the interior rearview mirror cover 1. At the same time, the spring piece on the inner side of the fixed bracket 31 abuts and triggers the micro switch, transmitting the signal to the vehicle controller, so that the vehicle controller controls the camera system 33 to start monitoring.

[0062] 2) Control process of camera assembly 3 rising: Manually raise camera assembly 3 to retract it into the inner rearview mirror cover 1, so that the micro switch on one side of the slide rail system 2 is turned off, and the vehicle controller controls the camera system 33 to turn off.

[0063] The specific control process is as follows: The camera assembly 3 is manually pushed upward, and the camera assembly 3 slides upward along the guide column 22 with the slider 23, so that the camera assembly 3 gradually retracts into the inner rearview mirror cover 1; at the same time, the end of the locking and unlocking mechanism 25 slides counterclockwise along the straight groove section 261 to the rising engagement section 262 of the annular groove section or clockwise to the rising exit section 263 of the annular groove section and then engages in the slot 265; at the same time, the spring 24 is compressed, and the spring 24 gives the slider 23 a downward elastic force and at the same time gives the locking and unlocking mechanism 25 a downward pulling force, so that the locking and unlocking mechanism 25 is stably engaged in the slot 265, realizing the stable locking and positioning of the locking and unlocking mechanism 25, the slider 23 and the camera assembly 3; at the same time, the spring piece on the inner side of the fixed bracket 31 disengages from the micro switch, the micro switch is de-energized, and the vehicle controller controls the camera system 33 to shut down.

[0064] In summary, the present invention has the following beneficial effects: by setting a sliding rail system inside the rearview mirror cover, and sliding the camera assembly on the sliding rail system, the present invention controls the camera assembly to slide up and down along the sliding rail system as needed, so that the camera assembly can extend or retract into the rearview mirror cover, which can take into account both riding comfort and privacy protection, and improve the customer experience.

[0065] The slide rail system is equipped with a locking and unlocking mechanism and a corresponding locking and unlocking groove. The locking and unlocking mechanism slides within the locking and unlocking groove. As the camera assembly slides downwards along the guide post with the slider, the locking and unlocking mechanism slides sequentially along the annular groove section and the straight groove section until it reaches the end of the straight groove section, thus achieving the downward sliding extension and positioning of the camera assembly. As the camera assembly slides upwards along the guide post with the slider, the locking and unlocking mechanism slides sequentially along the straight groove section and the annular groove section until it enters the slot of the annular groove section, thus achieving the upward sliding retraction and positioning of the camera assembly. This makes the raising and lowering operation of the camera assembly more convenient and faster.

[0066] A spring is installed on the inner side of the U-shaped connecting plate of the camera assembly's mounting bracket. A micro switch is installed on one side of the lower end of the slide rail system. When the camera assembly slides along the slide rail system to the bottom, that is, after the camera assembly extends out of the rearview mirror cover, the spring contacts and triggers the micro switch, transmitting a signal to the vehicle controller. This causes the vehicle controller to control the camera system to start monitoring. Similarly, when the camera assembly retracts into the rearview mirror cover, the camera system shuts down, ensuring the normal operation of the camera system.

[0067] The above description is merely an illustration of some principles of the present invention. This specification is not intended to limit the present invention to the specific structures and applicable scope shown. Therefore, all possible modifications and equivalents that may be used fall within the scope of the patent application of this invention.
