Description
Technical Field
The invention relates to the technical field of passive safety of automobiles, in particular to an automobile seat fixing device, an automobile seat and an automobile.
Background
When an automobile collides, the dissipation and migration of the kinetic energy of the automobile and the passengers play an important role in the safety protection of the automobile collision, and the degree of damage to the passengers is related to the posture regulation of the passengers, the degree of kinetic energy absorbed by different structures and the acting stroke when the kinetic energy is dissipated. By triggering the seat sliding during a collision, part of the kinetic energy of the passenger and the vehicle can be absorbed by the relevant energy absorbing mechanism during the sliding process, so that the ratio of the kinetic energy absorbed by the body of the passenger is reduced, the ratio of the kinetic energy absorbed by the structure of the vehicle is improved, and the riding and descending efficiency is improved.
Among them, a seat design that reduces whiplash in a rear-end collision has been examined by absorbing collision energy with a car seat slide. For example, patent document (CN 203496713U) discloses an intelligent translational energy-absorbing seat for self-adaptation in rear-end collision, which can slide by using inertial force of an occupant in the case of rear-end collision, and in the sliding process, collision kinetic energy is partially transferred into a sliding stroke and is absorbed by plastic deformation of an external damper, friction with a structure such as a guide rail in sliding, and the like.
In addition to the aforementioned vehicle seats that can be moved in the fore-and-aft direction, techniques that allow the vehicle seats to be moved laterally to absorb energy in a side impact are also disclosed in the relevant patent literature, and even further applications have been made, for example, the walwa company has marketed in 1991 a similar technique as part of a Side Impact Protection System (SIPS): the car seats in the driver and co-driver positions are fixed to a transverse high-strength tube, allowing the seats to be pushed toward the middle of the car body by mechanical means in the event of a side impact, and an energy absorbing device is installed in the middle of the two car seats, absorbing energy by plastic deformation.
The current commercial and published car seat designs focus on designs that allow only one degree of freedom to slide, and none allow the seat to move arbitrarily in multiple directions in a plane during a crash, thus failing to provide effective energy absorption protection in the event of a multi-angle crash other than a frontal side crash, and thus failing to meet occupant protection in multiple crash conditions.

The front, rear, left, and right in the embodiment of the present invention refer to front, rear, left, and right of the automobile, that is, front, rear, left, and right shown in fig. 1.
It will be appreciated that the seat mount 400 of the vehicle seat securing device is used to mount a vehicle seat within a vehicle, wherein the seat mount 400 may be coupled to the vehicle seat using fasteners (e.g., screws) and the securing frame 100 may be coupled to the floor of the vehicle using fasteners (e.g., screws).
As an example, as shown in fig. 1, the fixing frame 100 includes: an upper fixing frame 110, a middle fixing frame 120 and a lower fixing frame 130 which are sequentially laminated from top to bottom; a first guide groove is formed between the upper fixing frame 110 and the middle fixing frame 120, and the left and right moving part 320 moves along the first guide groove; the middle fixing frame 120 and the lower fixing frame 130 have a second guide groove therebetween, and the front and rear moving part 220 moves along the second guide groove. The structure of the fixing frame 100 is thus provided, and the left-right moving portion 320 and the front-rear moving portion 220 are prevented from being moved by each other. The upper and lower ends of the seat mount 400 extend to the outside of the intersection between the front-rear moving part 220 and the left-right moving part 320, and an upper stopper and a lower stopper are provided, so that the seat mount 400 can be fixed.
According to the automobile seat fixing device, when an automobile is in danger of collision in any direction in a horizontal plane, the first driving part 210 and/or the second driving part 310 are matched, the seat mounting seat 400 can be driven to drive the automobile seat to move in the front and rear directions and/or the left and right directions, in the moving process of the automobile seat, the collision kinetic energy is partially transferred to the moving stroke, and the energy absorption of the related energy absorption structure is combined, so that the kinetic energy ratio absorbed by the body of an occupant can be reduced, and further, the effective protection of the occupant can be realized when the automobile is in collision in any direction.
In some embodiments of the present invention, as shown in fig. 4 and 5, the first driving part 210 includes: a driving rack 211 provided on the fixed frame 100, a driving motor 212 provided on the front-rear moving part 220, and a driving gear 213 engaged with the driving rack 211; the driving motor 212 is used to drive the driving gear 213 to move on the driving rack 211.
Alternatively, the driving rack 211 may be fixed to the fixed frame 100 using screws, welding, or the like.
Further, as shown in fig. 5, in some embodiments of the present invention, the first driving part 210 further includes: a driving shaft 214 rotatably provided on the forward and backward moving part 220, a first bevel gear 215 provided on an output shaft of the driving motor 212, and a second bevel gear 216 provided on the driving shaft 214 and engaged with the first bevel gear 215, wherein the driving gear 213 is provided on the driving shaft 214. When the driving motor 212 is operated, the first bevel gear 215 rotates, the second bevel gear 216 also rotates, and the driving gear 213 is driven to rotate by the driving shaft 214, so that the driving gear 213 moves on the driving rack 211 through the engagement of the driving rack 211. The first bevel gear 215 is perpendicular to the rotation axis of the second bevel gear 216, so that the positional relationship between the driving gear 213 and the driving motor 212 can be adjusted according to the structure of the front-back moving part 220, so that the structure of the front-back moving part 200 is compact, for example, referring to fig. 5, the rotation axis of the driving gear 213 is distributed along the left-right direction, and the output axis of the driving motor 212 is distributed along the front-back direction. Of course, in other embodiments of the present invention, the driving rack 211 may be directly connected to the output shaft of the driving motor 212, and the rotation axis of the driving gear 213 and the output shaft of the driving motor 212 are in the same direction, for example, are all distributed along the left and right directions.
Alternatively, as shown in fig. 4, the front and rear moving part 220 has a plate-shaped structure, the front and rear moving part 220 has a first through hole for accommodating the driving motor 212, and the driving motor 212 may be fixed in the first through hole using a fastener (e.g., a screw); the front-rear moving portion 220 further has a second through hole for passing the seat mount 400 therethrough.
Alternatively, as shown in fig. 4, the left and right sides of the fixed frame 100 are provided with receiving grooves on the frame edges; the number of the driving racks 211 and the driving gears 213 is 2, the driving racks 211 are disposed in the corresponding receiving grooves, and the driving gears 213 are positioned at the left and right sides of the second bevel gear 216 and engaged with the corresponding driving racks 211. The driving motor 212 can drive the two driving gears 213 to rotate at the same time, which can save energy and effectively drive the seat mount 400 to move in the front and rear directions. Alternatively, the receiving groove has a groove-like structure penetrating left and right, and both left and right ends of the front and rear moving part 220 may protrude without interfering with movement thereof in the front and rear directions.
Further, as shown in fig. 3 and 5, in some embodiments of the present invention, the back-and-forth moving member 200 further includes a first locking portion 230; the first locking part 230 includes: a first lock gear 231 provided on the drive shaft 214, a lock motor 232 provided on the front-rear moving portion 220, a first lock rack 237 provided on the front-rear moving portion 220 slidably in the front-rear direction, and a second lock gear 233 engaged with the first lock rack 237; the locking motor 232 is used to drive the second locking gear 233 to rotate so as to drive the first locking rack 237 to slide in the front-rear direction until the end of the first locking rack 237 is inserted into or removed from the backlash of the first locking gear 231. When the locking motor 232 rotates in the forward direction, the second locking gear 233 drives the first locking rack 237 to move in the direction approaching to the first locking gear 231 until the end of the first locking rack 237 is inserted into the gap between the first locking gear 231, thereby preventing the driving shaft 214 from driving the driving gear 213 to rotate, and stopping the movement of the front-rear moving part 220, so that the locking of the car seat can be realized; similarly, when the locking motor 232 rotates in the opposite direction, the second locking gear 233 drives the first locking rack 237 to move away from the first locking gear 231 until the end of the first locking rack 237 is separated from the backlash of the first locking gear 231, so that the locking of the car seat by contact can be realized, and the position of the car seat can be adjusted.
Alternatively, the front and rear moving part 220 may have a third through hole accommodating the locking motor 232, and the driving locking may be fixed in the third through hole using a fastener (e.g., a screw).
Still further, as shown in fig. 5, in some embodiments of the present invention, the first locking part 230 further includes: a locking shaft 234 rotatably provided on the back-and-forth moving part 220, a third bevel gear 235 provided on an output shaft of the locking motor 232, and a fourth bevel gear 236 provided on the locking shaft 234 and engaged with the third bevel gear 235, wherein the second locking gear 233 is provided on the locking shaft 234. When the locking motor 232 is operated, the third bevel gear 235 rotates, the fourth bevel gear 236 also rotates, and the second locking gear 233 is driven to rotate by the locking shaft 234, and the first locking rack 237 moves in the front-rear direction by the engagement of the second locking gear 233. The third bevel gear 235 is perpendicular to the rotation axis of the fourth bevel gear 236, so that the positional relationship between the second locking gear 233 and the locking motor 232 can be adjusted according to the structure of the front-rear moving part 220, so that the structure of the front-rear moving part 200 is compact, for example, referring to fig. 5, the rotation axes of the second locking gear 233 are distributed along the left-right direction, and the output shafts of the locking motor 232 are distributed along the front-rear direction. Of course, in other embodiments of the present invention, the second locking gear 233 may be directly connected to the output shaft of the locking motor 232, and the rotation axis of the second locking gear 233 and the output shaft of the locking motor 232 are in the same direction, for example, are all distributed along the left and right directions.
On the premise that the back-and-forth moving member 200 includes the first locking portion 230, as shown in fig. 3 and 5, in some embodiments of the present invention, the back-and-forth moving member 200 further includes the second locking portion 240 and the flexible traction portion 250; the traction part 250 is slidably arranged on the front-back moving part 220 in a penetrating manner, the head part of the traction part 250 extends out from the front end of the front-back moving part 220 and is connected with the fixed frame 100, and the tail part of the traction part 250 extends out from the rear end of the front-back moving part 220 and is connected with the fixed frame 100; the second locking part 240 serves to lock the middle part of the traction part 250 to the front and rear moving part 220 or to unlock the middle part of the traction part 250, wherein the middle part of the traction part 250 and the first locking gear 231 are located on both front and rear sides of the front and rear moving part 220. After the second locking portion 240 releases the locking of the middle portion of the traction portion 250, when the front-rear movement portion 220 moves, a portion of the traction portion 250 made of flexible material penetrating the front-rear movement portion 220 is also changed all the time; when the second locking portion 240 locks the middle portion of the traction portion 250, the portion of the traction portion 250 penetrating the front-rear moving portion 220 will not change any more, so that the front-rear moving portion 220 cannot move in the front-rear direction, and the locking of the front-rear moving portion 220 is further realized. The second locking portion 240 is engaged with the first locking portion 230 to thereby lock the forward/backward moving portion 220 in both directions.
Alternatively, the traction portion 250 may be a rope similar to a mountain climbing static rope, which has the advantage of being less dense but able to withstand greater tension forces, and having less deformation during stretching. Because it is not capable of storing elastic energy, rebound does not occur during stretching of the first and second energy absorbing portions 260 and 270, and the diameter thereof can be adjusted according to a specific mechanism space.
Further, in some embodiments of the present invention, as shown in fig. 5, the second locking part 240 includes: a third lock gear 241 coaxially provided with the second lock gear 233, a second lock rack 242 slidably provided on the front-rear moving portion 220, and a restriction flap 244 rotatably provided on the front-rear moving portion 220; a fourth locking gear (not shown in the drawing) engaged with the second locking rack 242 is provided on the constraint lobe 244, and when the third locking gear 241 drives the second locking rack 242 to move in the front-rear direction, the fourth locking gear is used to drive the constraint lobe 244 to rotate, thereby locking or unlocking the traction portion 250. When the locking motor 232 rotates in the forward direction, the second locking gear 233 drives the first locking rack 237 to move in the direction approaching to the first locking gear 231 until the end of the first locking rack 237 is inserted into the backlash of the first locking gear 231, at the same time, the third locking gear 241 drives the second locking rack 242 to move in the direction far from the middle of the traction part 250, and the constraint flap 244 tightens the middle of the traction part 250 through the engagement of the fourth locking gear and the second locking rack 242, so that the front and rear locking of the front and rear moving part 220 is realized; when the locking motor 232 rotates in the opposite direction, the second locking gear 233 drives the first locking rack 237 to move in a direction away from the first locking gear 231 until the end of the first locking rack 237 is separated from the backlash of the first locking gear 231, and at the same time, the third locking gear 241 drives the second locking rack 242 to move in a direction close to the middle of the traction portion 250, and the constraint flap 244 releases the middle of the traction portion 250 by the engagement of the fourth locking gear with the second locking rack 242, so that the front and rear locking of the front and rear moving portion 220 is released.
Optionally, the constraint lobe 244 is integrally formed with the fourth lock gear or adjacent thereto by welding or the like. The rotation shaft of the fourth locking gear may be disposed on the front-rear moving part 220, and the direction of the rotation shaft is up-down.
Optionally, gear teeth are disposed on both left and right sidewalls of the second locking rack 242, as shown in fig. 4 and 5, and the number of the constraint lobes 244 is two and distributed on both left and right sides of the second locking rack 242. It will be appreciated that when the locking motor 232 is rotated in the forward direction, the two constraint lobes 244 move toward each other to effect locking of the traction portion 250; when the locking motor 232 is rotated in the opposite direction, the two constraint lobes 244 move in opposite directions to effect unlocking of the traction portion 250.
With the front-rear moving member 200 further including the traction portion 250, as shown in fig. 4, in some embodiments of the present invention, the head and tail of the traction portion 250 are located at both left and right sides of the front-rear moving portion 220; the back and forth moving member 200 further includes: the first energy absorbing part 260 and the second energy absorbing part 270, wherein the first energy absorbing part 260 is connected between the head part of the traction part 250 and the fixed frame 100, and the second energy absorbing part 270 is connected between the tail part of the traction part 250 and the fixed frame 100; when the collision strength of the automobile is greater than the strength threshold, the first locking rack 237 is broken and the front-back moving part 220 drives the first energy absorbing part 260 and the second energy absorbing part 270 to deform so as to absorb energy. When the collision strength (such as collision acceleration) of the automobile is greater than the strength threshold, the first locking rack 237 breaks, at this time, the middle part of the traction part 250 still penetrates through the front-rear moving part 220, and due to inertia, the seat mount 400 slides in the front-rear direction, so that the first energy absorbing part 260 and the second energy absorbing part 270 connected with the head and the tail of the traction part 250 are pulled, and the first energy absorbing part 260 and the second energy absorbing part 270 deform to absorb energy, thereby achieving the purpose of limiting force.
Alternatively, the traction portion 250 has a Z-shape (see fig. 4 and 5).
Optionally, the front and rear ends of the first locking rack 237 have different widths, and when the collision strength of the automobile is greater than the strength threshold, the junction between the front and rear ends of the first locking rack 237 is broken. The junctions of the front and rear ends of the first locking rack 237 may be set according to different situations.
Optionally, the first energy absorbing portion 260 and the second energy absorbing portion 270 are U-shaped metal sheets (e.g., steel sheets). The first and second energy absorbing portions 260 and 270 can be stretched and bent around the fixing cylinder (not shown in the drawing) of the fixing frame 100 at one end thereof to provide a stable platform force, and when the moving stroke is over, the seat mount 400 is not slid due to the restriction of the fixing frame 100, so that the collision process is completed. The steel sheet stretch bending has better reliability, and the force limiting size is easy to control by controlling the width of the steel sheet and the diameter of the fixed cylinder, so that the steel sheet stretch bending has higher controllability. The other ends of the first and second energy absorbing portions 260 and 270 may be connected to the traction portion 250 using a barb-shaped adapter tube made of metal.
In some embodiments of the present invention, the left-right moving member 300 has the same structure as the above-described front-rear moving member 200. Thus, the left-right moving member 300 and the front-rear moving member 200 are easily mass-produced.
The following describes a control flow of an automobile equipped with the above-mentioned automobile seat fixing device, wherein the automobile is equipped with an environment sensing and risk predicting module and a control module, see fig. 6:
the first stage is seat position comfort adjustment after seating of the occupant, which can be controlled autonomously by the occupant or predicted by the control module. During driving, the passenger can continue to control and adjust the comfort level of the seat position.
When the vehicle is started, the second stage is started, and the environment sensing and risk pre-judging module evaluates the driving risk in real time after sensing the environment. And when the risk reaches a certain threshold value, sending out an early warning signal. At this time, the control module has obtained the seat position, can judge whether to need to adjust according to the risk height and surplus energy absorption stroke, if need to adjust, the control module controls the first locking portion 230, the second locking portion 240 to adjust after releasing the locking to the seat, and the locking after the adjustment is accomplished. If the vehicle stops after the vehicle avoids the risk by decelerating or turning, the passenger can leave the seat; and if the vehicle continues to run after avoiding the risk, returning to the second stage.
If collision cannot be avoided, the third stage is entered. If the force limit of the first locking portion 230 is not reached during the collision, the occupant leaves the seat after the collision is completed; if the force limit is reached, the first locking portion 230 releases the locking or breaking, the seat enters a sliding energy absorbing state, and after the sliding stroke is finished, the seat is not moved until the collision is finished, and the occupant leaves the seat.
The environment sensing and risk pre-judging module comprises a road environment sensing unit and a risk pre-judging unit, wherein the road environment sensing unit can be composed of components such as a camera, a distance sensor and a radar, and can acquire parameters such as the distance between a vehicle and surrounding obstacles, the speed of the obstacles and the running direction of the obstacles. The risk pre-judging unit can judge whether the vehicle has collision risk or not through modeling and calculation. The control module is a PLC (Programmable Logic Controller ).
It should be noted that, after the adjustment travel related to the comfort level and the sliding energy absorption travel are combined into the same travel, the seat position after the comfort level adjustment will affect the sliding energy absorption travel, which may cause the energy absorbed by the sliding to be insufficient. Three methods can be used to solve this problem: 1) In the first stage, the comfort adjustable range is limited, a certain sliding energy absorption stroke is reserved, but the utilization rate of the comfort adjustment to the adjustable stroke is reduced; 2) In the second stage, the seat position is adjusted, a sliding energy absorption stroke is reserved, so that enough reserved sliding stroke cannot be ensured, but the adjustable range of comfort level is enlarged; 3) The two methods are combined.
Another embodiment of the present invention provides a car seat comprising a car seat fixture as described in any one of the above.
When the automobile is in danger of collision in any direction in the horizontal plane, the automobile seat can be driven to move along the front and rear directions and/or left and right directions by the cooperation of the first driving part 210 and/or the second driving part 310 of the automobile seat fixing device, in the moving process of the automobile seat, the collision kinetic energy is partially transferred to the moving stroke, and the energy absorption of the related energy absorption structure is combined, so that the ratio of the kinetic energy absorbed by the body of an occupant can be reduced, and further the effective protection of the occupant can be realized when the automobile is in collision in any direction.
