Description

Seat support system and vehicle

Technical Field

The present application relates to the field of vehicle technology, and 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 in the head-up range of a driver of a front windshield glass, so that the driver can avoid looking at the instrument by lowering the head, the time of eyeballs for the blind area in front is shortened, and the head-up display system has important value for reducing traffic accidents caused by the vague lowering of the head.

A Head Up Display (HUD) system is also called a Head Up Display system. The HUD can project important information such as speed, oil mass, rotating speed, navigation information and the like into the head-up range of a driver of the 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 starts to be highlighted in a specific scene, 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 and the feeling of a user are improved.

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 instrument desk 270 are both provided in the vehicle body 230, and the seat 250 and the instrument desk 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 driving mechanism 50, a linear transmission mechanism 70 and a supporting mechanism 90, wherein the vision sensor 10 is used for detecting the height of the driver's sight line in the vehicle 200, the controller 30 is electrically connected to the vision sensor 10, the electrically controlled driving mechanism 50 is electrically connected to the controller 30 and controlled by the controller 30, the linear transmission mechanism 70 is connected between the electrically controlled driving mechanism 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 electronically controlled driving mechanism 50 to move the linear actuator 70 and the supporting 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 for detecting the height of the line of sight of the driver in the vehicle 200, and the controller 30 is configured to control the electronically controlled driving mechanism 50 to drive the linear 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 driving mechanism 50 according to the height of the line of sight of the driver, the electronically controlled driving mechanism 50 is controlled to drive the linear 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 an embodiment of the present application, 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 comprises 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 features (e.g., pixel fraction, 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 human eyes, and the infrared characteristic image is subjected to image processing, so as to obtain spatial position information of the eyes 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 line range of the driver is located in the comfortable height area, the comfort level of the driver when watching the projected picture of the head-up display device 210 is high, and after the controller 30 obtains the sight line height of the driver, the electronic control driving mechanism 50 may be controlled to drive the seat 250 to move up and down, 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.

Referring to fig. 3, the seat support system 100 further includes a mounting mechanism 60, wherein the mounting mechanism 60 is used for fixing the electrically controlled driving mechanism 50 and the support mechanism 90, and is fixedly connected to the floor of the vehicle 250. In some embodiments, the mounting mechanism 60 and the floor of the vehicle 250 are integrally formed structures, such as by stamping, hot pressing, or casting from stainless steel. In other embodiments, where the mounting mechanism 60 can be prepared separately from the floor in a detachable connection, for example, the mounting mechanism 60 can be provided with a mounting member and a mating recess provided in the floor of the vehicle 250, and the mounting mechanism 60 can be secured to the floor of the vehicle 250 by a welding technique (e.g., laser welding, arc welding) after the mounting mechanism 60 is mounted in the mating recess via the mounting member.

In some embodiments, the mounting mechanism 60 includes a mount 610 and a carrier 630. The support 610 is a semi-cylindrical base, and a mounting portion for fixing and connecting to the floor is provided on a side of the base facing the floor. In fig. 3, the number of the holders 610 may be two, and the two holders 610 are oppositely spaced apart. The carrier 630 is disposed between the two holders 610 and is fixedly connected to the two holders 610, and specifically, the two holders 610 and the carrier 630 may be integrally formed structures. In the present application, two supports 610 are respectively disposed at two opposite ends of the carrier 630, and are used to fix the carrier 630.

The carrier 630 is generally cylindrical, e.g., cylindrical, square cylindrical, etc. In the present application, the carrier 630 is used to carry and fix the electronically controlled drive mechanism 50 and the support mechanism 90. For example, the carrier 630 is provided with a receiving groove for receiving the electronically controlled driving mechanism 50, and the electronically controlled driving mechanism 50 can be at least partially placed in the receiving groove, that is, the receiving groove can play a role in protecting and fixing the electronically controlled driving mechanism 50, so that the electronically controlled driving mechanism 50 can operate more stably. In addition, the receiving groove is located between the two supports 610, so that the installation space of the electrically controlled driving mechanism 50 can be effectively saved, and the overall structure of the seat supporting system 100 is more compact. The support mechanism 90 is also disposed on the carrier 630, and the fixing manner between the support mechanism 90 and the carrier 630 is described below.

In the embodiment of the present application, the electrically controlled driving mechanism 50 may be a rotating electric machine. In other embodiments, the electrically controlled driving mechanism 50 may be a rotating motor with a reduction box, or may be a rotary driving device such as a rotary steering engine. In still other embodiments, the electronically controlled driving mechanism 50 may be a linear driving device such as a linear motor or an air cylinder. Specifically, the electrically controlled driving mechanism 50 is electrically connected to the controller 30, and operates according to a control command and a target movement stroke input by the controller 30.

Referring to fig. 4, the linear transmission mechanism 70 includes a driving member 710 and a fitting member 730, the driving member 710 is connected to the electrically controlled driving mechanism 50, and the fitting member 730 is connected to the driving member 710 and moves linearly along a predetermined direction under the driving of the driving member 710. Specifically, the implementation manner of the linear transmission mechanism 70 in the embodiment of the present application is determined based on the operation manner of the electronically controlled driving mechanism 50.

In some embodiments, where the electronically controlled drive mechanism 50 is a rotary drive, the linear actuator 70 may be a lead screw and nut mechanism. As shown in fig. 4, the linear actuator 70 includes a lead screw 710 (i.e., a driving member 710) disposed along the predetermined direction H and a nut 730 (i.e., a fitting member 730) fitted to the lead screw 710. One end of the screw 710 is connected to the electrically controlled driving mechanism 50 and is driven by the electrically controlled driving mechanism 50 to rotate, the nut 730 is inserted into the screw 710 and is driven by the screw 710 to perform linear motion along a predetermined direction H (i.e., an axial direction of the screw 710), so as to drive the supporting mechanism 90 connected to the nut 730 to move, thereby adjusting the lifting height of the seat 250. The predetermined direction H is a height direction of the seat 250. Specifically, the nut 730 may be a bent tube nut, a circulator nut, an end cap nut. The application does not limit the specific structure of the feed screw-nut mechanism.

In some embodiments, where the electronically controlled drive mechanism 50 is a rotary drive, the linear drive mechanism 70 may be a rack and pinion mechanism. Referring to fig. 5, the linear transmission mechanism 70 includes a cylindrical gear 710 (i.e., a driving member 710) and a rack 730 (i.e., a mating member 730) disposed along a predetermined direction H. The center of the cylindrical gear 710 is connected to the output shaft 510 of the electric control driving mechanism 50, and the rack 730 is connected to the supporting mechanism 90 and meshed with the cylindrical gear 710. When the cylindrical gear 710 is driven by the output shaft 510 to rotate, it drives the rack 730 to translate along the predetermined direction H through the meshing relationship, so that the supporting mechanism 90 translates along the predetermined direction H, thereby achieving the purpose of adjusting the height of the seat 250. The cylindrical gear 710 may be a single gear or a gear module composed of a plurality of gears, and is not particularly limited in this application.

In some embodiments, electronically controlled drive mechanism 50 is a linear drive device, such as a linear motor. Referring to fig. 6, the linear actuator 70 includes a stator 710 (i.e., a driving member 710) and a mover 730 (i.e., a mating member 730). The stator 710 is at least partially disposed inside the housing of the linear motor, and the stator 710 may also be integrated with the electronically controlled driving mechanism 50. The mover 730 is disposed in a predetermined direction H and magnetically coupled with the stator 710. When the electrically controlled driving mechanism 50 is in a working state, the electrically controlled driving mechanism 50 converts electric energy into electromagnetic force between the stator 710 and the mover 730, and the mover 730 moves along the predetermined direction H under the action of the electromagnetic force, so as to drive the supporting mechanism 90 connected with the mover 730 to translate along the predetermined direction H, thereby achieving the purpose of adjusting the height of the seat 250.

In some embodiments, electronically controlled drive mechanism 50 is a linear drive device, such as a pneumatic cylinder. Referring to fig. 7, the linear actuator 70 includes a piston 710 (i.e., a driving member 710) and a boss 730 (i.e., a fitting member 730). The piston 710 is movably disposed inside a cylinder body of the cylinder and translates in a predetermined direction H under the pressure inside the cylinder body. One side of the boss 730 is fixedly connected with one side of the piston 710, which is away from the air chamber of the cylinder, and the other side of the boss 730 is connected with the supporting mechanism 90, and the supporting mechanism 90 is forced to translate along the predetermined direction H under the driving of the piston 710, so as to achieve the purpose of adjusting the height of the seat 250. Specifically, the boss 730 and the piston 710 may be integrally formed.

In the embodiment of the present application, the number of the electrically controlled driving mechanism 50 and the linear transmission mechanism 70 is not limited, that is, the number of the electrically controlled driving mechanism 50 and the linear transmission mechanism 70 may be multiple, and the multiple linear transmission mechanisms 70 are disposed at intervals and connected to the multiple electrically controlled driving mechanisms 50 in a one-to-one correspondence manner. Referring to fig. 2 again, in fig. 2, the number of the electrically controlled driving mechanisms 50 and the number of the linear transmission mechanisms 70 are two, and the two linear transmission mechanisms 70 are disposed at intervals between the supporting mechanism 90 and the corresponding electrically controlled driving mechanism 50. This application is through setting up a plurality of straight line drive mechanism 70 to for seat 250 provides firm support, can make seat 250 more stable when going up and down, improved the comfort of driver when taking.

Referring again to fig. 3, in the present embodiment, the supporting mechanism 90 is adapted to the fitting member 730 and is used for supporting the bottom of the seat 250. The support mechanism 90 includes a guide 92 and a first support 94. Specifically, the first support 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 a fastener or the like to function as support and rotation. In the present application, the first supporting member 94 is drivingly connected to the fitting member 730, and is driven by the fitting member 730 to translate along the predetermined direction H. It should be noted that the "transmission connection" between the first supporting member 94 and the mating member 730 should be understood to refer to a position and a connection relationship between the two, such as a physical connection (e.g. a hinge, a pivot, etc.) between the two, or a direct physical connection (e.g. a hinge, a pivot, etc.) between the two, or a contact connection between the two to transmit a motion in a pushing manner (e.g. a surface contact connection, or a nested contact connection, etc.), or a relatively fixed connection to transmit a motion.

The guide member 92 is disposed along the predetermined direction H, and the first support member 94 is movably connected to the guide member 92, that is, the guide member 92 serves to restrict the moving direction of the first support member 94 during the movement of the first support member 94, so that the first support member 94 can be smoothly moved along the predetermined direction H, which improves the comfort of the driver in riding.

In some embodiments, the guide 92 includes a plurality of guide bars 921 spaced apart from each other, and the plurality of guide bars 921 are each disposed along the predetermined direction H. One end of the guide bar 921 is fixedly connected to the mounting mechanism 60, and the guide bar 921 is movably disposed through the first supporting member 94. In some embodiments, the first supporting member 94 is provided with a plurality of matching portions corresponding to the guide bars 921 one to one, and the guide bars 921 can be at least partially inserted into the corresponding matching portions. Therefore, when the fitting member 730 moves the first support 94 up and down, the plurality of guide rods 96 can limit the lifting direction of the first support 94, that is, the first support 94 can be lifted up and down smoothly along the predetermined direction H, thereby improving the riding comfort of the driver. Specifically, the engagement portion may be a support hole corresponding to the guide bar 921. In fig. 3, the number of the guide bars 921 is two, and the two guide bars 921 are uniformly provided at one side of the first support member 94, so that the first support member 94 is more stable when being lifted.

In some embodiments, the guiding element 92 further includes a limiting portion 923, and the limiting portion 923 is connected to an end of the guide bar 921 remote from the mounting mechanism 60, that is, the first supporting member 94 is located between the limiting portion 923 and the mounting mechanism 60. The limiting portion 923 may be a block or a strip, which may be integrally formed with one end of the guide bar 921 away from the mounting mechanism 60, and the other end of the guide bar 921 may be fixedly connected to the carrier 630 by welding or the like. In some embodiments, the guide 92 includes a plurality of guide bars 921, and the stopper portion 923 is connected between the plurality of guide bars 921. In fig. 3, the guide 92 is a "door" structure, a first receiving space is formed between the two guide rods 921 and the limiting portion 923, and the electric control driving mechanism 50 and the linear transmission mechanism 70 are disposed in the first receiving space, so that the overall structure of the seat supporting system 100 is more compact. In addition, the guide 92 may also protect the electronically controlled drive 50 and the linear actuator 70.

The guide 92 in this embodiment of the application can limit the highest position of the first supporting member 94 in the ascending process by providing the limiting portion 923, and in addition, the guide bar 921 is further connected to the supporting member 630, that is, the supporting member 630 can limit the lowest position of the first supporting member 94 in the descending process, so that the first supporting member 94 is more stable and reliable in ascending and descending.

In some embodiments, the support mechanism 90 further includes a second support 96 and a pivot assembly 98, the second support 96 being rotatably coupled to the mounting mechanism 60 and adapted to support the back of the seat 250. The second supporting member 96 may be a block-shaped body or a plate-shaped body, and referring to fig. 3 again, the second supporting member 96 includes a first fixing rod 961 and a second fixing rod 963. The first fixing rods 961 are substantially cylindrical, for example, cylindrical or square cylindrical, and the number of the first fixing rods 961 is two, two first fixing rods 961 are oppositely disposed, and one end of each first fixing rod 961 is fixedly connected to the mounting mechanism 60. The second fixing rod 963 is fixedly connected to the other end of the two first fixing rods 961, is located between the two first fixing rods 961, and plays a role in fixing and supporting the first fixing rods 961. That is, the second support member 96 in the present application is entirely of a "door" type structure, a second accommodating space is formed between the two first fixing rods 961 and the second fixing rod 963, and the guide 92 is disposed in the second accommodating space, so that the overall structure of the seat supporting system 100 is more compact.

In some embodiments, the second support 96 may be rotatably coupled to the mounting mechanism 60 by a pivot assembly 98. Specifically, the rotating shaft assembly 98 may be a washer rotating shaft, a linear rotating shaft, a wrapping rotating shaft, a torsion spring rotating shaft, or the like. In some embodiments, the seat support system 100 further includes an electrically controlled spindle driving mechanism 80, wherein the spindle 981 of the spindle assembly 98 is connected to the electrically controlled spindle driving mechanism 80, and the electrically controlled spindle driving mechanism 80 drives the spindle 981 to rotate, so as to rotate the second supporting member 96 relative to the mounting mechanism 60. Further, the electric control driving mechanism 80 for the rotating shaft is electrically connected to the controller 30, and drives the rotating shaft assembly 98 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 visual 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 visual 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 driving mechanism 50, and sends a work instruction and the target movement stroke to the electronically controlled driving mechanism 50. For example, the target height position may be divided into 3 levels, each level being defined by a height interval; if the current sight line height exceeds the current level height interval, the controller 30 sends a height adjusting command to the electrically controlled driving mechanism 50. And the electronic control driving mechanism 50 works after receiving the height adjusting instruction, controls the linear transmission mechanism 70 to drive the supporting mechanism 90 to move, calibrates the stroke in real time, and 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 feed back the height feedback information to the electronic control driving mechanism 50, and when the electronic control driving mechanism 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 provided with the seat support system provided by the embodiment of the application, the seat support system is arranged at the bottom of a seat, a vision sensor of the seat support system can be used for detecting the sight height of a driver of the vehicle, and a controller is configured to control an electric control driving mechanism to drive a linear transmission mechanism and a support mechanism to move according to detection data of the vision sensor.

The rotation stroke of the electric control driving mechanism can be determined according to the sight height of the 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.
