Description

Seat support system and vehicle

Technical Field

The present application relates to the field of vehicle technology, in particular to a seat support system and a vehicle.

Background

When the vehicle is running at high speed, especially at high speed at night, the driver may look at the instrument display or the sound of the center console, and if an emergency occurs in front of the vehicle, the driver may have to take effective measures to cause an accident. In order to avoid the situation, some high-grade vehicles are provided with a head-up display system which can display related information on the head-up range of a driver of a front windshield glass, so that the driver can avoid looking down at an instrument, the time of eyeballs for vision blind areas in front is shortened, and the head-up display system has important value for reducing traffic accidents caused by the vague head lowering.

Head Up Display (HUD) systems are also known as Head Up Display systems. The HUD can project important information such as speed, oil mass, rotating speed, navigation information and the like into a driver head-up range of a front windshield, and the display position and the display brightness are adjustable. The driver can conveniently check the required information almost without changing the focal length and the watching range of eyes.

Typically, the HUD is mounted directly to the dashboard of the vehicle via a mounting bracket to facilitate projection onto the front windshield. However, the height of the projection picture of the HUD cannot be flexibly adjusted in the driving process, so that the problem that the display information cannot be seen clearly and cannot be seen in a specific scene begins to be highlighted, for example, the projection picture with a uniform height position cannot be completely adapted to drivers with different heights, and therefore, a scheme is necessary to be researched, so that the height of the projection picture of the HUD can be adapted to the height of the driver, and the experience of a user is improved.

It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, the present embodiment provides a seat support system 100 and a vehicle 200 equipped with the seat support system 100. The vehicle 200 includes a heads-up display device 210, a vehicle body 230, a seat 250, and the seat support system 100 described above. The seat 250 and the console 270 are both provided in the vehicle body 230, and the seat 250 and the console 270 are provided at an opposing interval. The heads-up display device 210 is mounted to the instrument desk 270, which may include an imaging system such as a projection lens, a projection chip, etc., so as to project toward a front windshield of the vehicle 200. The seat support system 100 is disposed at the bottom of the seat 250 between the floor within the vehicle body 230 and the seat 250 for supporting the seat 250.

Referring to fig. 2, the seat supporting system 100 includes a vision sensor 10, a controller 30, an electrically controlled rotary driving element 50, a cam transmission mechanism 70 and a supporting mechanism 90, the vision sensor 10 is used for detecting the height of the driver's sight line of the vehicle 200, the controller 30 is electrically connected to the vision sensor 10 and the electrically controlled rotary driving element 50, the electrically controlled rotary driving element 50 is electrically connected to the controller 30 and controlled by the controller 30, the cam transmission mechanism 70 is connected between the electrically controlled rotary driving element 50 and the supporting mechanism 90, and the supporting mechanism 90 is used for supporting the bottom of the seat 250. The controller 30 is configured to control the electrically-controlled rotary drive 50 to move the cam transmission 70 and the support mechanism 90 according to the detection data of the vision sensor 10 so as to adjust the height of the seat 250.

Therefore, the vision sensor 10 of the seat support system 100 can be used to detect the height of the line of sight of the driver of the vehicle 200, and the controller 30 is configured to control the electronically controlled rotary driving element 50 to drive the cam transmission mechanism 70 and the support mechanism 90 to move according to the detection data of the vision sensor 10, for example, after the controller 30 determines the target movement stroke of the electronically controlled rotary driving element 50 according to the height of the line of sight of the driver, the electronically controlled rotary driving element 50 is controlled to drive the cam transmission mechanism 70 to move according to the target movement stroke, so that the support mechanism 90 is forced to move to support the seat 250, thereby achieving the purpose of adjusting the height of the seat 250, and further enabling the driver on the seat 250 to be at a height convenient for viewing the head up display device 210, and improving the experience of the driver.

In the present embodiment, the vision sensor 10 includes at least one of the following sensors: image sensors, eye movement sensors, high-speed near-infrared cameras, and the like.

For example, in some examples, where the vision sensor 10 includes an image sensor, it may be a CMOS high-speed image sensor and may be disposed on the heads-up display device 210 (e.g., integrated within the heads-up display device 210) or on the instrument desk 270 and disposed toward the seat 250. In operation, the CMOS high-speed image sensor acquires an eye image of the driver on the seat 250, and analyzes spatial position information (e.g., orientation information with respect to the CMOS high-speed image sensor) of the eye of the driver according to image characteristics (e.g., pixel ratio, angle, etc.) of the eye image, and obtains height information of the eye of the driver in the vehicle 200, thereby obtaining the height of the line of sight of the driver.

As another example, when the vision sensor 10 includes a high-speed near-infrared camera, the high-speed near-infrared camera is used to capture an infrared characteristic image of the human eye, and the infrared characteristic image is subjected to image processing, so as to obtain spatial position information of the eye of the driver. For another example, when the vision sensor 10 includes an eye movement sensor, it may use a near-infrared light source in the eye movement sensor to generate a reflected image on the cornea and pupil of the eye of the user, and then use two image sensors to collect the images of the eye and the reflected image, and perform image processing on the images of the eye and the reflected image, so as to obtain the spatial position information of the eye of the driver.

In the embodiment of the present application, the controller 30 may be a control chip, an integrated circuit board, etc., wherein an image processing chip may be built in the controller 30 for processing the image acquired by the vision sensor 10, and the image processing means as exemplified above may be all completed by the controller 30. Specifically, the controller 30 is configured to acquire an eye image of the driver captured by the vision sensor 10, obtain spatial position information of the eyes of the driver by using a corresponding image processing and analyzing method, convert the spatial position information into height information of the eyes of the driver in the vehicle 200, and further obtain the sight height of the driver. Further, the controller 30 may obtain a corresponding comfortable height area (the comfortable height area may be the existing data built in the head-up display device 210 or the controller 30) according to the actual projected picture height of the head-up display device 210, that is, when the sight range of the driver is located in the comfortable height area, the comfort level when the driver watches the projected picture of the head-up display device 210 is high, and after the controller 30 obtains the sight height of the driver, the electrically controlled rotary driving element 50 may be controlled to drive the seat 250 to ascend and descend, so that the eyes of the driver are located in the comfortable height area, so that the driver can watch the projected picture of the head-up display device 210 conveniently.

In the present embodiment, the electrically controlled rotary drive 50 may be a rotary electric machine. In other embodiments, the electrically controlled rotary driving element 50 may be a rotary motor with a reduction box, or may be a rotary driving device such as a rotary steering engine or a rotary cylinder. Specifically, the electrically controlled rotary driving element 50 is electrically connected to the controller 30, and rotates according to the control command and the target movement stroke input by the controller 30.

Referring to fig. 3, in the present embodiment, the cam transmission mechanism 70 includes a cam plate 701 and an input shaft 703, the input shaft 703 is connected to the electrically controlled rotary driving element 50, the cam plate 701 is connected to the input shaft 730 in a rotation-stop manner, that is, the cam plate 701 and the input shaft 730 are relatively fixed, and when the electrically controlled rotary driving element 50 drives the input shaft 703 to rotate, the cam plate 701 follows the input shaft 703 to rotate synchronously.

In some embodiments, the cam plate 701 has a mounting slot 7010 that mates with the input shaft 703, the cam plate 701 is fixedly coupled to one end of the input shaft 703 via the mounting slot 7010, and the other end of the input shaft 703 is coupled to the electronically controlled rotary drive 50. When the electrically controlled rotary driving member 50 rotates by driving the input shaft 703, the input shaft 703 directly drives the cam plate 701 to rotate, and further drives the supporting mechanism 90 adapted to the cam plate 701 to move, so as to adjust the lifting height of the seat 250.

In other embodiments, referring to fig. 4, the cam actuator 70 further comprises an actuator 705. The transmission 705 includes the driving wheel 72, the planetary wheel 74, the central wheel 76 and the output shaft 78. The input shaft 703 is connected to the axis of the driving wheel 72, that is, the driving wheel 72 is connected to the electrically controlled rotary driving member 50 through the input shaft 703, the planetary gear 74 is engaged between the driving wheel 72 and the central wheel 76, the output shaft 78 is connected to the axis of the central wheel 76, and one end of the output shaft 78 is fixedly connected to the cam plate 701. When the electrically controlled rotary driving member 50 rotates, it drives the driving wheel 72 to rotate through the input shaft 703, the driving wheel 72 drives the central wheel 76 to rotate through the meshing relationship of the planetary wheels 74, the central wheel 76 drives the cam plate 701 to rotate through the output shaft 78, and further drives the supporting mechanism 90 matched with the cam plate 701 to move, so as to adjust the lifting height of the seat 250.

Specifically, in the present embodiment, the driving wheel 72 may be a gear shaft, and the driving wheel 72 and the input shaft 703 may be integrally formed as a whole of the gear shaft and directly connected to the electrically controlled rotary driving element 50. In other embodiments, the drive wheel 72 is a separate gear that is coaxially coupled to the input shaft 703 via a coupling or spline, for example. The driving wheel 72 may be a spur gear, a helical gear, or a herringbone gear. In the present embodiment, the driving wheel 72 is illustrated as a cylindrical gear in fig. 4, it should be understood that in other embodiments, the driving wheel 72 may be an annular gear (as in fig. 5) to form a "planetary gear train" in a general sense together with the planetary gear 74 and the central gear 76, so as to ensure that the driving wheel 72 can bear a large load and the transmission is smooth.

The planet gears 74 can be of cylindrical gear configuration, which can be spur, helical, or herringbone gear configurations. The planetary gear 74 is mainly used for transmitting the power of the driving wheel 72 and realizes the change of the number of revolutions to reach the movement speed required by the design. In some embodiments, when the driving wheel 72 is in an annular gear structure (as shown in fig. 5), the planet wheels 74 may be disposed inside the annular gear and engaged with the annular gear, and at this time, the number of the planet wheels 74 may be multiple, for example, the number of the planet wheels may be three, three planet wheels 74 are sequentially disposed at intervals along the circumferential direction of the annular gear, and all the three planet wheels 74 may be engaged with the annular gear and all engaged with the central wheel 76, and at this time, the three planet wheels 74 can ensure that the bearing capacity of the transmission mechanism 705 is large and the transmission is smooth; further, the rotating shafts of the three planetary wheels 74 can be connected to each other by a three-shaft retainer and the relative positional relationship can be kept unchanged, so that the structural stability of the transmission mechanism 705 is further improved.

In this embodiment, the center wheel 76 may be a gear shaft, and the center wheel 76 and the output shaft 78 may be integrally formed as a single piece of the gear shaft. In other embodiments, the center wheel 76 is a separate gear that is coaxially coupled to the output shaft 78 by a coupling or spline, or the like. The central gear 76, which may be a spur gear, helical gear, or herringbone gear, is engaged with the planets 74 and is configured to translate motion of the planets 74. In some embodiments, as shown in fig. 5, when the drive wheel 72 is in the configuration of an annulus gear, the center wheel 76 may be disposed at the center of the annulus gear and coaxially with the annulus gear; in this case, if there are three planet wheels 74, the three planet wheels 74 surround the outer periphery of the center wheel 76 and are distributed at equal intervals. In the embodiment of the application, the planetary gear train is used as the transmission mechanism, the transmission is stable and reliable, the bearing capacity is high, and the requirement scene of seat height adjustment can be met.

Referring to fig. 4 again, in the present embodiment, the output shaft 78 may be a long shaft passing through the center of the center wheel 76, and one end of the output shaft 78 is exposed at one side of the center wheel 76, and the output shaft 78 is used for mounting the cam plate 701.

In the present embodiment, the support mechanism 90 is adapted to the cam plate 701 and adapted to support the bottom of the seat 250. Wherein the support mechanism 90 comprises a follower 92 and a support seat 94, the support seat 94 being arranged between the cam plate 701 and the seat 250 and adapted to support the bottom of the seat 250. Further, the supporting seat 94 may be a block-shaped seat body or a plate-shaped seat body, which may be assembled to the bottom of the seat 250 by fasteners or the like to perform supporting and rotating functions. The follower 92 is connected to the cam plate 701 and is drivingly connected to the support base 94 to transmit the rotational movement of the input shaft 703, thereby driving the support base 94 to translate along a predetermined direction H, wherein the predetermined direction H is the height direction of the seat 250. It should be noted that the "transmission connection" between the driven member 92 and the supporting seat 94 should be understood to refer to a position and a connection relationship between the two, which can transmit the motion, for example, the two can be physically connected by a connecting member (for example, a connection relationship of hinge, pivot, etc.), or the two can be directly physically connected (for example, a connection relationship of hinge, pivot, etc.), or the two can be in contact connection and transmit the motion in a pushing manner (for example, a surface contact connection, a nested contact connection, etc.), or the two can be relatively fixedly connected to transmit the motion.

In the embodiment shown in fig. 4, the cam plate 701, the support seat 94, and the follower 92 are arranged substantially side by side in the predetermined direction H, and the outer peripheral wall of the cam plate 701 is in contact with the follower 92. Further, cam plate 701 may be an eccentric cam, for example, whose position connected to output shaft 78 does not coincide with its geometric center, and the position of the contact point on the peripheral wall of cam plate 701, which contacts follower 92, is constantly changed as cam plate 701 rotates with output shaft 78, and the distance between the position of the contact point and the rotational center of cam plate 701 determines the distance between support seat 94 and the rotational center (i.e., the relative height of support seat 94), so that, when cam plate 701 rotates, it can support seat 94 by follower 92 for translational movement in predetermined direction H. In other examples, the cam disc 701 may be a regular cam structure, for example, the cam disc 701 may be an elliptical cam, and the position of the cam disc 701 connected to the output shaft 78 coincides with the geometric center thereof, which makes it easy to determine the distance between a point on the peripheral wall of the cam disc 701 and the geometric center, so that the relative height of the contact point position where the cam disc 701 contacts the follower 92, that is, the lifting height of the support seat 94, can be calculated as long as the rotation angle of the cam disc 701 is known.

Further, referring to fig. 4 again, in some embodiments, the follower 92 is an engaging wheel 921 fixedly disposed relative to the supporting seat 94, and in order to prevent the relative position between the cam plate 701 and the engaging wheel 921 from deviating, a limiting groove 941 may be disposed on a side of the engaging wheel 921 facing the cam plate 701, and the cam plate 701 is at least partially embedded in the limiting groove 941, so as to improve the overall stability of the seat supporting system 100.

In the embodiment of the present application, the number of the support mechanisms 90 is not limited, that is, the number of the cam plates 701 may be plural, and a plurality of the cam plates 701 are disposed at intervals from each other and are in rotation stop connection with the input shaft 703. Referring to fig. 6, in fig. 6, the number of the cam plates 701 is two, two cam plates 701 are disposed at opposite ends of an input shaft 703, the input shaft 703 is connected to the electronically controlled rotary driving member 50, and the two cam plates 701 are driven to rotate synchronously by the electronically controlled rotary driving member 50. In some other embodiments, the plurality of cam plates 701 may be connected to a plurality of transmission mechanisms (not shown in fig. 6) in a one-to-one correspondence, and the electronically controlled rotary drive 50 drives the plurality of transmission mechanisms via the input shaft 703 to effect synchronized rotation of the plurality of cam plates 701. Through the arrangement, the energy output by the electric control rotary driving part 50 can be efficiently utilized to lift, and the output motion is symmetrical and stable.

Similarly, in the seat support system 100 provided in the present application, the number of the followers 92 is plural, and the plural followers 92 are connected to the support base 94 and are disposed in one-to-one correspondence with the plural cam plates 701, respectively. In fig. 6, there are two followers 92, and the two followers 92 are connected to the two cam plates 701 in a one-to-one correspondence so as to provide a firm support for the seat 250.

Referring to fig. 7, in the embodiment of the present application, the supporting mechanism 90 further includes a first supporting member 97 and a plurality of guiding rods 96, wherein the first supporting member 97 and the supporting seat 94 are disposed at an interval and are adapted to be fixedly connected to a body of the vehicle 200. Wherein the first supporting member 97 is provided with a supporting hole 971 corresponding to the guide bar 96. A plurality of guide rods 96 are provided at intervals from each other, and one end of each guide rod 96 is fixedly connected to one side of the support base 94 facing the cam plate 701, and the other end is slidably inserted into the corresponding support hole 971. The axial direction of the guide rods 96 is parallel to the predetermined direction H, so that when the cam plate 701 drives the support seat 94 to ascend and descend, the plurality of guide rods 96 can limit the ascending and descending direction of the support seat 94, that is, the support seat 94 can ascend and descend smoothly along the predetermined direction H under the guidance of the plurality of guide rods 96, and the riding comfort of a driver is improved. In fig. 7, the number of the guide rods 96 is four, and the four guide rods 96 are uniformly arranged around the support base 94, so that the support base 94 is more stable when being lifted.

In some embodiments, the support mechanism 90 further comprises a second support 98 and a pivot mechanism 99, the second support 98 and the first support 97 being rotatably coupled and adapted to support the back of the seat 250. The second supporting member 98 may be a block-shaped body or a plate-shaped body, which may be rotatably connected with the first supporting member 97 by a rotating shaft mechanism 99. Specifically, the rotating shaft mechanism 99 may be a pad rotating shaft, a linear rotating shaft, a rolling rotating shaft, a torsion spring rotating shaft, or the like. In some embodiments, the seat supporting system 100 further includes a rotating shaft electrically controlled rotary driving element 60, and the rotating shaft 991 of the rotating shaft mechanism 99 is connected to the rotating shaft electrically controlled rotary driving element 60 and drives the rotating shaft 991 to rotate through the rotating shaft electrically controlled rotary driving element 60, so as to realize the rotation of the second supporting element 98 relative to the first supporting element 97. Further, the electrically controlled rotary driving element 60 of the rotating shaft is electrically connected to the controller 30, and drives the rotating shaft mechanism 99 to rotate based on the angle control signal sent by the controller 30, so as to adjust the angle of the back (i.e. the backrest) of the seat 250, wherein the angle control signal is determined according to the detection data of the vision sensor 10, therefore, the controller 30 in the present application can not only adjust the height of the seat 250 based on the detection data of the vision sensor 10, but also adjust the angle of the backrest based on the detection data, so that the driver feels more comfortable when viewing the projected image.

When the seat support system 100 provided by the present application is in operation, for example, during driving of the vehicle 200, the vision sensor 10 acquires an eye image of the driver in real time and transmits the eye image to the controller 30, the controller 30 analyzes the eye image to detect the height of the driver's sight line, calculates the target height position of the eyes of the driver, converts the target height position into the target movement stroke of the electronically controlled rotary driving element 50, and sends a work instruction and the target movement stroke to the electronically controlled rotary driving element 50. For example, the target height position may be divided into 3 levels, each level being defined by a height interval; if the current viewing height exceeds the current level height interval, the controller 30 sends a height adjustment command to the electronically controlled rotary drive 50. And after receiving the height adjusting instruction, the electrically controlled rotary driving part 50 works to control the cam transmission mechanism 70 to drive the supporting mechanism 90 to move and calibrate the stroke in real time, when the supporting mechanism 90 moves to enable the real-time sight height of the driver to reach a height interval of a target grade, the controller 30 gives height feedback information to be fed back to the electrically controlled rotary driving part 50, and when the electrically controlled rotary driving part 50 stops working, the height adjustment is completed. Otherwise, if the height of the seat 250 needs to be lowered, the working process is the reverse of the above process, and the description of the present application is omitted. In the above operation, the generation of the instruction and the signal transmission may be implemented by those skilled in the art according to the common general knowledge in the art.

In the seat support system and the vehicle equipped with the seat support system provided by the embodiment of the application, the seat support system is arranged at the bottom of a seat, the vision sensor can be used for detecting the sight height of a driver in the vehicle, and the controller is configured to control the electric control rotary driving piece to drive the cam transmission mechanism and the support mechanism to move according to detection data of the vision sensor.

The rotation stroke of the electric control rotary driving part can be determined according to the sight height of a driver, and a corresponding relation exists between the rotation stroke and the sight height, so that the actual height of the seat can correspond to the sight height of the driver, and the aim of specifically adjusting the height of the seat according to the sight height of the driver can be fulfilled. And a comfortable height area exists between the sight height of the driver and the projection picture of the head-up display device, namely, when the sight range of the driver is positioned in the comfortable height area, the comfort level of the driver when watching the projection picture of the head-up display device is higher, therefore, the controller only needs to adjust the height of the seat according to the sight height data of the driver, so that the adjusted sight height data falls into the comfortable height area, the sight height of the driver can be adapted to the projection picture of the head-up display device, and the comfort level of the driver when watching the projection picture is improved.
