Description

Technical Field

[0001] The invention relates to a spine support control system and method for a car seat and the car seat. Background Art

[0002] Currently, in the automotive industry, seat backrests are adjusted during normal use based on the driver's and passenger's riding habits. However, in existing safety regulations, seat backs are adjusted to the designed position (typically around 25 degrees) for crash dummy injury assessments. However, in actual use, during a collision, the seat back may not always be in the designed position. For example, if a passenger is lying or partially reclining in the seat during a collision, the occupant's spine may be subjected to significant pressure, potentially resulting in injury.

[0003] Generally, sitting postures can be categorized into three types: 1) normal driving posture, 2) working posture, and 3) leisure posture. Specifically, the normal driving posture means the driver and passengers are fully focused on the vehicle's movements, with the seatback typically adjusted to approximately 25 degrees. In the working posture, the driver and passengers are not focused on the vehicle's movements and can work or entertain themselves, with the seatback adjusted to approximately 45 degrees. In the leisure posture, the driver and passengers are completely focused on the vehicle's movements and can rest with their eyes closed, with the seatback adjusted to 60 degrees or even higher.

[0004] When the vehicle is involved in a head-on collision while sitting in a working or leisure position (semi-reclining or fully reclining), the torso of the driver or passenger will slide downward along the seat back due to inertia, while the seat basin supports the occupant and the lap belt of the seat restrains the pelvis of the driver or passenger, resulting in opposite movement and squeezing of the upper torso and pelvis of the driver or passenger. Existing research and tests have shown that such a condition will cause compression of the spine and easily lead to irreparable or even life-threatening injuries.

[0005] With the development of automobile intelligence, automatic driving or unmanned driving technology, there is a need for an automatic control system that can protect the spine of occupants in a car in a collision state. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defect that the car seat in the prior art is difficult to protect the occupant's spine during a collision, and to provide a spine support control system, method and car seat for a car seat.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A control system for a spinal support of a car seat is characterized in that the control system includes: a support body, which is movably connected to the car seat; a detection unit; and an information prompting unit, which is electrically connected to the detection unit; the detection unit is used to detect the car seat and send a signal to the information prompting unit to enable the information prompting unit to prompt the occupant to place the support body against the occupant's armpit.

[0009] In this solution, the above-mentioned structural form is adopted. In the normal driving and riding posture, the support body in the control system can be lifted or flipped up to support the occupant's armpits to reduce the pressure on the spine; when the occupants in the vehicle are in a working sitting position (half-lying) and a leisure sitting position (fully lying), the support body makes up for the lack of restraint of the occupants along the seat back. Through the support under the armpits, the pressure on the spine can be reduced and the driving comfort can be improved. When the vehicle collides head-on or side, the support body improves the occupant's movement posture, relieves the pressure on the spine, and improves the safety of the occupants. The detection part in the control system is used to detect the inclination angle of the car seat back and to send a corresponding electrical signal to the information prompt part. After receiving the signal, the information prompt part prompts the occupant to press the support body against the armpit. When the vehicle collides head-on or side, the control system can improve the occupant's movement posture, relieve the pressure on the spine, and improve the safety of the occupants.

[0010] Preferably, the detection unit is used to detect the angle between the backrest of the car seat and the vertical direction, and send the signal to the information prompt unit.

[0011] In this solution, the above-mentioned structural form is adopted. When the detection unit detects that the angle between the seat back of the car seat and the vertical direction is too large, the detection unit sends an electrical signal to the information prompt unit, prompting the occupant to place the support body against the armpit, which is beneficial to protecting the occupant's riding safety.

[0012] Preferably, the detection unit is used to detect whether the support body is against the armpit of the occupant and to send the signal to the information prompting unit.

[0013] In this solution, the above-mentioned structural form is adopted, and the detection unit will detect whether the support body is against the occupant's armpit. If the occupant presses the support body against the armpit after the information prompt unit issues the information prompt, the information prompt unit will stop the information prompt. If the detection unit detects that the occupant does not press the support body against the armpit after the information prompt unit issues the prompt, the detection unit will send a corresponding signal to the information prompt unit to prompt the occupant to press the support body against the armpit again.

[0014] Preferably, the control system further comprises a driving mechanism, which is connected to the support body and is used to drive the support body to move, so that the other end of the support body extends from the car seat to the armpit of the occupant and is used to support the armpit of the occupant.

[0015] In this solution, the above-mentioned structural form is adopted, and the passenger can drive the support body to move by controlling the driving mechanism, so that the other end of the support body extends from the car seat to the passenger's armpit and is used to support the passenger's armpit. At the same time, the driving mechanism can also drive the support body to move up and down on the seat back to adjust the distance between the support body and the passenger's armpit, which is conducive to making the passenger obtain a more comfortable support effect, and at the same time is conducive to meeting the support needs of passengers of different shapes and sizes.

[0016] Preferably, the detection unit is electrically connected to the driving mechanism and is used to control the driving mechanism to be turned on or off.

[0017] In other embodiments, the detection part is electrically connected to the drive mechanism. When the detection part detects that the inclination angle of the seat back is too large, or when the occupant receives a message prompt from the information prompt part but still does not press the support body against the armpit, the detection part will send a corresponding electrical signal to the drive mechanism and cause the drive mechanism to open. The drive mechanism will automatically drive the support body to move to the occupant's armpit. At the same time, when the detection part detects that the support body has moved to the appropriate position, the detection part sends a corresponding electrical signal to the drive mechanism and causes it to close, thereby preventing the support body from moving excessively and causing discomfort in the occupant's armpit.

[0018] Preferably, the control system also includes a pressure detection unit and a locking component, the pressure detection unit is used to detect the force applied to the support body, and the pressure detection unit is electrically connected to the locking component; the pressure detection unit is used to detect the force value of the support body and compare it with its internal set value, when the force value is greater than or equal to the set value, the pressure detection unit is used to close the locking component to enable the support body to move on the car seat; when the force value is less than the set value, the pressure detection unit is used to open the locking component to achieve locking and fixation between the support body and the car seat.

[0019] In this solution, the above-mentioned structural form is adopted, and the locking mechanism has a positioning effect on the support body, so that the support body is not easy to slip when it is in a supporting state under a certain load, and the occupant obtains a certain supporting force during use. At the same time, the pressure detection part effectively prevents the support force provided by the support body to the occupant from being greater than the range that the occupant can bear, thereby protecting the occupant.

[0020] A car seat is characterized in that it comprises the above-mentioned control system for spine support of the car seat.

[0021] In this solution, the aforementioned structure is employed in a vehicle seat with a spinal support control system. In the event of a head-on collision, particularly when the seatback angle is relatively large, such as when sitting for work or leisure, the occupant will slide downward along the seatback under the influence of inertia. The underarm support provides support during this downward movement. When the pressure on the support exceeds a set value, the support plastically deforms or descends under the influence of damping, absorbing the inertial force on the occupant's torso and alleviating pressure on the occupant's spine. Similarly, in the event of a side collision, the support maintains the upper torso's posture, working in conjunction with the side airbag, distal airbag, and air curtain to mitigate injuries resulting from secondary collisions.

[0022] A control method for a spinal support for a car seat, characterized in that the control method utilizes the above-mentioned control system for the spinal support for a car seat, and the control method includes the following steps: the detection unit is used to detect the car seat and send the signal; the information prompting unit receives the signal and prompts the occupant.

[0023] Preferably, the detection unit is used to detect the car seat and to send the signal, specifically including: the detection unit is used to detect the angle between the backrest of the car seat and the vertical direction and to send the signal to the information prompt unit; and / or, the detection unit is used to detect whether the support body is against the armpit of the occupant and to send the signal to the information prompt unit.

[0024] Preferably, before the detection unit is used to detect the car seat and send the signal, the method includes: detecting whether the passenger is sitting on the car seat.

[0025] Preferably, before the detection unit is used to detect the car seat and send the signal, and after detecting whether the passenger is sitting on the car seat, the method further includes: determining whether the passenger is wearing a seat belt.

[0026] When the detection unit detects that there is an occupant on the car seat, the detection unit will also detect whether the occupant is wearing a seat belt. When the occupant is not wearing a seat belt, the detection unit will send a signal to the information prompt unit, and the information prompt unit will send a message to remind the occupant to wear the seat belt. After the occupant wears the seat belt, the detection unit will detect the inclination angle of the car seat back. If the inclination angle of the car seat back exceeds the set value, the detection unit will send a signal to the information prompt unit, and the information prompt unit will remind the occupant to place the support body against the armpit. If the detection unit detects that the support body has already rested against the occupant's armpit, it will send a signal to the information prompt unit to stop the information prompt. If the detection unit detects that the support body does not rest against the occupant's armpit, the detection unit will send a signal to the information prompt unit, and the information prompt unit will again remind the occupant to place the support body against the armpit.

[0027] On the basis of conforming to the common sense in this field, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0028] The positive progress effect of the present invention is:

[0029] The detection unit within the control system is used to detect the inclination angle of the car seat back and to send a corresponding electrical signal to the information prompt unit. After receiving the signal, the information prompt unit prompts the occupant to place the support body against the armpit. When the vehicle collides head-on or sideways, the control system can improve the driver and passenger's movement posture, relieve spinal pressure, and improve the safety of the driver and passenger.

[0042] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0043] The embodiment of the present invention provides a control system for the spine support of a car seat 4, such as Figure 1-3As shown, the control system includes: a support body 1, which is movably connected to the car seat 4; a detection part; an information prompting part, which is electrically connected to the detection part; the detection part is used to detect the car seat 4 and to send a signal to the information prompting part, so that the information prompting part is used to prompt the occupant to place the support body 1 against the occupant's armpit.

[0044] Adopting the above-mentioned structural form, one end of the support body 1 in the control system is a fixed end, and the fixed end of the support body 1 is installed in the adjustment part 2 on the car seat 4. The adjustment part 2 is provided with an adjustment body and an adjustment track 21. The support body 1 is fixedly connected to the adjustment body, and the adjustment body drives the support body 1 to slide on the adjustment track 21. The other end of the support body 1 is a movable end so that the support body 1 can move relative to the car seat 4. When the support body 1 is in a non-working state, the support body 1 is folded on both sides of the car seat 4 so that it does not affect the activities of the occupants in the car; when the support body 1 is in a working state, the occupant extends the support body 1 from both sides of the car seat 4 to the armpits on both sides of the occupant by adjusting the movable end of the support body 1. Its position can be adjusted according to the body shape of the driver and the occupant. A detection part and an information prompt part are also provided in the control system. The information prompt part is electrically connected to the detection part. The detection part is used to detect the inclination angle of the backrest of the car seat 4 and to send a corresponding electrical signal to the information prompt part. After receiving the signal, the information prompt part prompts the occupant to press the support body 1 against the armpit. In a normal driving or riding posture, the support body 1 in the control system can be lifted or flipped up to support the occupant's armpits to reduce the pressure on the spine; when the occupants in the vehicle are in a working sitting position (half-lying) or a leisure sitting position (fully lying), the support body 1 makes up for the lack of restraint of the occupants along the seat back direction. Through the support under the armpits, the pressure on the spine can be reduced and the driving comfort can be improved. When the vehicle collides head-on or sideways, the support body 1 improves the occupant's movement posture, relieves the pressure on the spine and improves the safety of the occupants. At the same time, the control system can provide information prompts to the occupants in a timely manner, which is conducive to further reducing the risk of spinal injury to the occupants.

[0045] As a preferred embodiment, Figure 1-3 As shown, the detection unit is used to detect the angle between the backrest of the car seat 4 and the vertical direction, and send a signal to the information prompt unit.

[0046] According to actual conditions, the passenger sitting postures can generally be summarized into three types, namely normal driving posture, working posture and leisure posture. The normal driving posture means that the driver and passengers pay full attention to the driving conditions of the vehicle. Generally, the seat back adjustment position is designed to be about 25 degrees; in the working posture, the driver and passengers will not pay attention to the driving conditions of the vehicle, and can work or entertain in the vehicle, with the seat back adjusted to about 45 degrees; and for the leisure posture, the driver and passengers will not pay attention to the driving of the vehicle at all, and can close their eyes to rest, with the seat back adjusted to 60 degrees or even a larger angle. In order to ensure the safety of the passengers during the driving of the car, for example, when the detection unit detects that the angle between the seat back of the car seat 4 and the vertical direction is greater than 25 degrees, the detection unit sends an electrical signal to the information prompt unit, prompting the passengers to press the support body 1 against their armpits, which is beneficial to protecting the passengers' riding safety.

[0047] As a preferred embodiment, Figure 1-3 As shown, the detection unit is used to detect whether the support body 1 is against the occupant's armpit and to send a signal to the information prompt unit.

[0048] For example, when the detection unit detects that the angle between the seat back of the car seat 4 and the vertical direction is greater than 25 degrees, the detection unit sends an electrical signal to the information prompt unit to prompt the occupant to place the support body 1 against the armpit. After that, the detection unit will detect whether the support body 1 is against the occupant's armpit. If the occupant places the support body 1 against the armpit after the information prompt unit sends the information prompt, the information prompt unit will stop the information prompt. If the detection unit detects that the occupant does not place the support body 1 against the armpit after the information prompt unit prompts, the detection unit will send a corresponding signal to the information prompt unit to prompt the occupant to place the support body 1 against the armpit again.

[0049] As a preferred embodiment, Figure 1-3 As shown, the control system further includes a driving mechanism, which is connected to the support body 1 and is used to drive the support body 1 to move so that the other end of the support body 1 extends from the car seat 4 to the occupant's armpit and is used to support the occupant's armpit.

[0050] The control system also provides a driving mechanism, which is an electric component and is connected to the support body 1. When the occupant wants to place the support body 1 against his armpit, the occupant can control the driving mechanism to drive the support body 1 to move, so that the other end of the support body 1 extends from the car seat 4 to the occupant's armpit and is used to support the occupant's armpit. At the same time, the driving mechanism can also drive the support body 1 to move up and down on the seat back to adjust the distance between the support body 1 and the occupant's armpit, which is conducive to making the occupant obtain a more comfortable support effect, and is also conducive to meeting the support needs of occupants of different shapes and sizes.

[0051] In other embodiments, the driving mechanism may also adopt a manual mechanical structure, and the distance between the support body 1 and the occupant's armpit is adjusted manually, which can avoid the influence of electronic failure on the adjustment process of the support body 1.

[0052] As a preferred embodiment, Figure 1-3 As shown, the detection part is electrically connected to the driving mechanism and is used to control the driving mechanism to be on or off.

[0053] In other embodiments, the detection part is electrically connected to the drive mechanism. When the detection part detects that the inclination angle of the seat back is too large, or the occupant receives a message prompt from the information prompt part but still does not press the support body 1 against the armpit, the detection part will send a corresponding electrical signal to the drive mechanism and cause the drive mechanism to open. The drive mechanism will automatically drive the support body 1 to move to the occupant's armpit. At the same time, when the detection part detects that the support body 1 moves to the appropriate position, the detection part sends a corresponding electrical signal to the drive mechanism and causes it to close, thereby preventing the support body 1 from moving excessively and causing discomfort in the occupant's armpit.

[0054] As a preferred embodiment, Figure 1-3 As shown, the control system also includes a pressure detection unit and a locking component. The pressure detection unit is used to detect the force applied to the support body 1, and the pressure detection unit is electrically connected to the locking component. The pressure detection unit is used to detect the force value of the support body 1 and compare it with its internal set value. When the force value is greater than or equal to the set value, the pressure detection unit is used to close the locking component to enable the support body 1 to move on the car seat 4; when the force value is less than the set value, the pressure detection unit is used to open the locking component to achieve locking and fixation between the support body 1 and the car seat 4.

[0055] In other embodiments, the control system is further provided with a pressure detection unit and a locking component. When the occupant presses the support body 1 against his armpit and adjusts the adjustment body up and down to a suitable position, the locking component is locked to position the support body 1. The pressure detection unit is used to detect the force on the support body 1, and the pressure detection unit is electrically connected to the locking component. When the vehicle collides, the occupant will slide down along the seat back due to inertia in a tilted state. During this process, the pressure detection unit detects the force value on the support body 1 in real time and compares it with the internal set value of the pressure detection unit. When the force value on the support body 1 is greater than or equal to the set value of the pressure detection unit, the pressure detection unit causes the locking component to enter an open state to enable the support body 1 to move on the car seat 4; when the force value on the support body 1 is less than the set value of the pressure detection unit, the pressure detection unit causes the locking component to remain in a locked state to achieve locking and fixation between the support body 1 and the car seat 4. The locking mechanism has a positioning effect on the support body 1, so that the support body 1 is not easy to slip when it is in a supporting state under a certain load, and the occupant obtains a certain supporting force during use. At the same time, the pressure detection part effectively prevents the support body 1 from providing a supporting force greater than the range that the occupant can bear, thereby protecting the occupant.

[0056] The embodiment of the present invention provides a car seat 4, such as Figure 1-3 As shown, the vehicle seat 4 adopts the above-mentioned control system for the spinal support of the vehicle seat 4 .

[0057] When this spinal support control system is implemented in a vehicle seat 4, in the event of a head-on collision, especially when the seatback angle is relatively large, such as when sitting for work or leisure, the occupant will slide downward along the seatback due to inertia. The support body 1 under the armpits supports the occupant during this downward movement. When the pressure on the support body 1 exceeds a set value, the support body 1 plastically deforms or descends due to damping, absorbing the inertial force on the occupant's torso and relieving pressure on the occupant's spine. Similarly, in the event of a side collision, the support body 1 maintains the upper torso's posture, working together with the side airbag, distal airbag, and air curtain to reduce injuries caused by secondary collisions.

[0058] The embodiment of the present invention provides a control method for the spinal support of a car seat 4, such as Figure 4 As shown, the control method employs the aforementioned control system for spinal support in a vehicle seat 4 and includes the following steps: a detection unit for detecting the vehicle seat 4 and issuing a signal; and an information prompting unit for receiving the signal and providing a notification to the occupant. Specifically, the detection unit for detecting the vehicle seat 4 and providing a signal includes: detecting the angle between the backrest of the vehicle seat 4 and the vertical direction and providing a signal to the information prompting unit; and / or detecting whether the support body 1 abuts the occupant's armpit and providing a signal to the information prompting unit.

[0059] When there is an occupant on the car seat 4, the detection unit will detect the inclination angle of the car seat 4 backrest in real time. When the inclination angle of the car seat 4 backrest is too large, the detection unit will send a signal to the information prompt unit, and the information prompt unit will send a message to prompt the occupant to place the support body 1 against the armpit. After the information prompt unit sends the prompt, the detection unit will detect whether the occupant places the support body 1 against the armpit. If the detection unit detects that the support body 1 has already placed against the occupant's armpit, it will send a signal to the information prompt unit to stop the information prompt. If the detection unit detects that the support body 1 has not placed against the occupant's armpit, the detection unit will send a signal to the information prompt unit, and the information prompt unit will again prompt the occupant to place the support body 1 against the armpit.

[0060] As a preferred embodiment, Figure 4 As shown, before the detection unit is used to detect the vehicle seat 4 and send a signal, it includes: detecting whether there is an occupant sitting on the vehicle seat 4.

[0061] Before detecting the tilt angle of the car seat 4 backrest, the detection unit will first detect whether there is a passenger on the car seat 4. If the detection unit detects that there is a passenger on the car seat 4 and the tilt angle of the seat backrest is greater than the set value, the detection unit sends a signal to the information prompt unit, and the information prompt unit sends a message to prompt the passenger to place the support body 1 against the armpit.

[0062] As a preferred embodiment, Figure 4 As shown, before the detection unit is used to detect the car seat 4 and send a signal, and after detecting whether there is an occupant sitting on the car seat 4, the process also includes: determining whether the occupant is wearing a seat belt.

[0063] When the detection unit detects that there is an occupant on the car seat 4, the detection unit will also detect whether the occupant is wearing a seat belt. When the occupant is not wearing a seat belt, the detection unit will send a signal to the information prompt unit, and the information prompt unit will send a message to remind the occupant to wear the seat belt. After the occupant wears the seat belt, the detection unit will detect the inclination angle of the backrest of the car seat 4. If the inclination angle of the backrest of the car seat 4 exceeds the set value, the detection unit will send a signal to the information prompt unit, and the information prompt unit will remind the occupant to place the support body 1 against the armpit. If the detection unit detects that the support body 1 has already rested against the occupant's armpit, it will send a signal to the information prompt unit to stop the information prompt. If the detection unit detects that the support body 1 does not rest against the occupant's armpit, the detection unit will send a signal to the information prompt unit, and the information prompt unit will again remind the occupant to place the support body 1 against the armpit.

[0064] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of the present invention.
