[0030] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. Embodiments of the present utility model will be described in detail below.

[0031] Reference will be made below to Figures 1 - 4 Describe the seat adjustment device 100 according to an embodiment of the present utility model. The seat adjustment device 100 according to an embodiment of the present utility model can be applied to a vehicle.

[0032] In conjunction with Figures 1 - 4As shown in the figure, the seat adjustment device 100 according to the embodiment of the present invention may mainly include: a base 10, a first support member 20, and a second support member 30. Specifically, the base 10 can be used to support the seat pan 201 of the seat 200, and the seat adjustment device 100 can be installed between the seat 200 and the floor of the vehicle 1000. In this way, while ensuring the setting reliability of the vehicle 1000 seat 200, the angle adjustment of the seat 200 relative to the vehicle 1000 can be realized. In the embodiment of the present invention, the connection manner between the base 10 and the floor of the vehicle 1000 includes but is not limited to screwing, and the connection manner between the bottom of the seat pan 201 of the seat 200 and the first support member 20 includes but is not limited to bolt connection.

[0033] Among them, the base 10 is arranged in the front-rear direction, the first support member 20 extends in the front-rear direction, and the rear end of the first support member 20 is rotatably connected to the rear end of the base 10. With such a setting, on the one hand, the first support member 20 can be connected to the base 10, which can ensure the structural reliability of the first support member 20 in the seat adjustment device 100. On the other hand, the first support member is movable relative to the base 10, so as to facilitate the adjustment function of the seat adjustment device 100. In the embodiment of the present invention, the rear end of the first support member 20 and the rear end of the base 10 can be hinged by bolts, so that the rear end of the first support member 20 is rotatably arranged relative to the rear end of the base 10.

[0034] Furthermore, the first end of the second support member 30 is slidably arranged on the base 10 in the front-rear direction, so that the first end of the second support member 30 can slide in a direction parallel to the extension direction of the first support member 20. The second end of the second support member 30 is rotatably connected to the front end of the first support member 20. This can not only enable power transmission between the first support member 20 and the second support member 30, but also ensure that the second support member 30 always moves within a plane parallel to the front-rear direction. In this way, it can be ensured that the first support member 20 and the second support member 30 always move within a plane parallel to the front-rear direction.

[0035] In addition, in the embodiment of the present invention, both the first support member 20 and the second support member 30 are located below the seat pan 201 of the vehicle 1000 seat 200, and the first support member 20 is fixedly connected to the bottom of the seat pan 201. In this way, the front end of the first support member 20 rotates around its rear end within a plane parallel to the front-rear direction and the up-down direction, and the seat pan 201 of the vehicle 1000 seat 200 can be adjusted to a large inclination angle through the seat adjustment device 100. In the embodiment of the present invention, the second end of the second support member 30 and the front end of the first support member 20 can be hinged by bolts, so that the second end of the second support member 30 is rotatably arranged relative to the front end of the first support member 20.

[0036] It should be noted that in the embodiments of the present utility model, the large inclination angle of the toilet bowl 201 is the angle between the first support member 20 and the base 10 after the front end of the toilet bowl 201 is lifted. When the toilet bowl 201 is adjusted to the large inclination angle state, a person sitting on the toilet bowl 201 can lean backward.

[0037] In the embodiments of the present utility model, the structure of the seat adjusting device 100 is simple and the production cost is low, which can make it easier for consumers to accept and choose, so as to increase the diversity of consumer choices.

[0038] In practical applications, when the toilet bowl 201 is in the normal state, both the first support member 20 and the second support member 30 are arranged parallel to the front-rear direction, the toilet bowl 201 is not lifted, and the backrest angle of the seat 200 is between 23° and 25°. When the toilet bowl 201 is adjusted to the large inclination angle state, the toilet bowl 201 is lifted, and the backrest angle of the seat 200 exceeds 45°, so that the first end of the second support member 30 slides backward on the base 10. In this way, the second end of the second support member 30 also slides backward. The front end of the first support member 20 is connected to the second end of the second support member 30. Therefore, the front end of the first support member 20 rotates backward in a plane parallel to the front-rear direction with the rear end of the first support member 20 as the center, so as to lift the front end of the toilet bowl 201 backward until the toilet bowl 201 is adjusted to the appropriate large inclination angle state.

[0039] Similarly, when the toilet bowl 201 is adjusted back from the large inclination angle state to the normal state, the first end of the second support member 30 can be made to slide forward on the base 10. In this way, the second end of the second support member 30 also slides forward, and drives the front end of the first support member 20 to rotate downward with the rear end of the first support member 20 as the center, thereby enabling the front end of the toilet bowl 201 to descend until the toilet bowl 201 returns to the normal state.

[0040] Combined with Figure 2As shown, the seat adjustment device 100 further includes a sliding block 40, which is slidably matched with the base 10, and the first end of the second bracket member 30 is rotatably connected to the sliding block 40. Specifically, the sliding block 40 is located on the base 10, which can ensure the reliability of the setting of the sliding block 40 in the seat adjustment device 100. The sliding block 40 is connected to the first end of the second bracket member 30, and the sliding block 40 is slidably matched with the base 10, so that the sliding block 40 can drive the first end of the second bracket member 30 to slide along the front and rear directions. Further, the first end of the second bracket member 30 is rotatable relative to the sliding block 40, so that when the front end of the first bracket member 20 is rotatable relative to the rear end of the first bracket member 20, the second end of the second bracket member 30 can be driven to rotate relative to the first end of the second bracket member 30, so that the adjustment function of the seat adjustment device 100 can be realized, the smoothness of the operation of the seat adjustment device 100 can be ensured, and then the smoothness of the tilt adjustment of the seat pan 201 of the seat 200 of the vehicle 1000 can be ensured, which is conducive to improving the user experience. In the embodiment of the present invention, the first end of the second bracket member 30 and the sliding block 40 may be hinged via a local protruding feature, so that the first end of the second bracket member 30 may be rotatably disposed relative to the sliding block 40 .

[0041] Combination Figures 2 - 4 As shown, the seat adjustment device 100 also includes a driving assembly 50, two bases 10, the two bases 10 are arranged at intervals in the left and right directions, the first bracket members 20 and the second bracket members 30 are both two, and the two first bracket members 20, the two second bracket members 30 and the two bases 10 are arranged in a one-to-one correspondence.

[0042] Specifically, two bases 10 are arranged at intervals on the left and right sides of the bottom of the basin 201 to maintain the balance of the basin 201. There are two first brackets 20 and two second brackets 30, which are arranged on the left and right bases 10 in a one-to-one correspondence, so that the inclination angle of the basin 201 can be adjusted on both sides of the bottom of the basin 201 to ensure the stability of the basin 201 when it is at a large inclination angle.

[0043] Furthermore, a driving assembly 50 is arranged between the two bases 10, and the driving assembly 50 can output power outward. The sliding blocks 40 on the two bases 10 are transmission-connected to the driving assembly 50, so that the output power of the driving assembly 50 can be transmitted to the left and right sliding blocks 40 to drive the left and right sliding blocks 40 to slide relative to the left and right bases 10 respectively, and then the first ends of the second bracket members 30 on the left and right sides can be driven to slide forward and backward, so that the front end of the basin 201 can be driven to lift backward.

[0044] Combination Figures 2 - 4As shown, the driving assembly 50 includes a driving member 51, a first transmission rod 52, and a second transmission rod 53. The first transmission rod 52 extends in the front-rear direction and is in transmission connection with the driving member 51, so that the driving member 51 can directly transmit power to the first transmission rod 52 and ensure that the driving force is transmitted in the front-rear direction.

[0045] Further, the second transmission rod 53 extends in the left-right direction and is respectively connected to the sliding blocks 40 on the two bases 10. The first transmission rod 52 is in transmission connection with the second transmission rod 53, so that the driving force on the first transmission rod 52 can be transmitted to the sliding blocks 40 on the left and right sides along the second transmission rod 53 respectively. Furthermore, the second transmission rods 53 on the left and right sides can be selectively driven to move in the front-rear direction simultaneously, so as to ensure that the front ends of the left and right first support members 20 can be lifted or lowered simultaneously, and the lifting stability of the toilet bowl 201 can be ensured.

[0046] Combined with Figures 2 - 4 As shown, the driving assembly 50 further includes a nut 54. The first transmission rod 52 is a lead screw, and the nut 54 is sleeved on the lead screw and is in threaded transmission cooperation with the lead screw. The second transmission rod 53 is connected to the nut 54. Specifically, in the embodiment of the present invention, the first transmission rod 52 and the second transmission rod 53 are driven by the nut 54. The nut 54 and the lead screw are in threaded cooperation. The driving member 51 drives the lead screw to rotate. Through the threaded cooperation, the nut 54 can move back and forth on the lead screw, and the second transmission rod 53 can move back and forth following the nut 54, thereby driving the sliding blocks 40 on the left and right sides to slide back and forth to drive the seat 200 adjustment mechanism to adjust the large inclination angle of the toilet bowl 201. In the embodiment of the present invention, the driving member 51 includes but is not limited to a driving motor, and the output shaft of the driving motor is in transmission connection with the lead screw to drive the lead screw to rotate.

[0047] Combined with Figure 2 As shown, two limit blocks 11 are provided on the base 10, which can be used to limit the sliding range of the sliding block 40. The two limit blocks 11 are spaced apart in the front-rear direction, and the sliding block 40 is located between the two limit blocks 11. In this way, the front and rear limit blocks 11 can respectively limit the forward and backward movement ranges of the sliding block 40. With such a setting, on the one hand, it can ensure that the large inclination angle of the toilet bowl 201 adjustment is within the preset range, and on the other hand, it can prevent the seat adjustment device 100 from having dead points during operation.

[0048] Further, the sliding block 40 is selectively and limit-fitted with the two limiting blocks 11. When the sliding block 40 slides forward, the sliding block 40 gradually approaches the front limiting block 11 until the sliding block 40 slides to be limit-fitted with the front limiting block 11, and then the seat adjusting device 100 adjusts the seat pan 201 to the maximum inclination angle. When the sliding block 40 slides backward, the sliding block 40 gradually approaches the rear limiting block 11 until the sliding block 40 slides to be limit-fitted with the rear limiting block 11, and then the seat adjusting device 100 adjusts the seat pan 201 to return to the normal state.

[0049] Combined with Figure 2 and Figure 4 As shown, the seat adjusting device 100 further includes a sliding guide rod 60. The sliding guide rod 60 extends forward and backward, and both ends are respectively connected to the two limiting blocks 11. The sliding block 40 is sleeved on the sliding guide rod 60 and is in sliding fit with the sliding guide rod 60. Specifically, to ensure the sliding stability of the sliding block 40 between the front and rear limiting blocks 11, the seat adjusting device 100 in the present invention is provided with a sliding guide rod 60 extending forward and backward between the front and rear limiting blocks 11. The sliding block 40 is sleeved on the sliding guide rod 60 and is in sliding fit with the sliding guide rod 60. This can not only ensure the sliding stability of the sliding block 40 in the front-rear direction, but on the other hand, prevent the sliding path of the sliding block 40 from deviating, so as to ensure the sliding reliability of the first end of the second support member 30 on the base 10, and further ensure the operation reliability of the seat adjusting device 100.

[0050] Combined with Figures 2 - 4 As shown, the seat adjusting device 100 further includes a generator. The generator includes a housing 70 and a generator body. An installation bracket 12 is provided at the front end of the base 10. The housing 70 is disposed on the installation bracket 12. The driving member 51 is movably disposed in the housing 70. The generator body is disposed in the housing 70 and is located on the front side of the driving member 51. The generator body selectively drives the driving member 51 to move backward. Specifically, in the embodiment of the present invention, the front ends of the two bases 10 are connected with an installation bracket 12, which can enable the base 10 to provide a stable and reliable supporting effect on the installation bracket 12. The housing 70 of the generator is connected to the installation bracket 12, which can enable the installation bracket 12 to provide a stable and reliable supporting effect on the housing 70 of the generator. Thus, the structural reliability of the housing 70 of the generator on the seat adjusting device 100 can be ensured. In the embodiment of the present invention, the installation bracket 12 and the base 10 can be connected by welding, and the housing 70 and the installation bracket 12 can be connected by welding.

[0051] Further, at least a part of the front end of the driving member 51 is embedded in the housing 70 of the generator and is located at the rear side of the generator body within the housing 70. In this way, after the generator body expands, the driving member 51 can be pushed backward from the front side of the driving member 51, so that the driving member 51 can push the first transmission rod 52, the nut 54, and the second transmission rod 53 to move backward as a whole. Since the generator body expands rapidly and generates a large thrust, the driving member 51 can be quickly driven to slide backward. The driving member 51 pushes the sliding block 40 and drives the second support member 30 to move backward, so that the second end of the second support member 30 can drive the front end of the first support member 20 to quickly descend, and then the front end of the toilet bowl 201 can be quickly lowered to the normal state. During this process, the driving member 51 does not drive the second support member 30 to rotate, but pushes the second support member 30 and the sliding block 40 to move backward together, and there is no relative displacement between the second support member 30 and the sliding block 40. In this way, when the vehicle 1000 suddenly collides, the seat 200 can be quickly adjusted back to the normal state to reduce the injury received by the human body on the seat 200, so that while realizing the large inclination angle adjustment function of the toilet bowl 201, the use safety of the seat adjustment device 100 can be increased. In the embodiment of the present invention, the generator body includes, but is not limited to, an ignition tablet and an airbag member, and the driving member 51 can be pushed out of the housing 70 by the impact force generated by the explosion of the ignition tablet or by the inflation of the airbag member.

[0052] It should be noted that when the toilet bowl 201 is in the large inclination angle state, the spine of the human body is bent. Once the vehicle 1000 collides, the spine is subjected to a large force, and the airbag cannot protect the head, and the seat belt will be strangled into the abdomen. In this state, the human body will be more injured. Therefore, when the vehicle 1000 collides, the seat 200 needs to be quickly restored to the normal state to reduce the injury received by the human body.

[0053] According to an embodiment of the present invention, the seat adjustment device 100 further includes a controller, and the controller is electrically connected to the driving member 51. Specifically, the controller can control the seat adjustment device 100 by controlling the driving member 51. The controller is signal-connected to the vehicle machine and can obtain the real-time vehicle speed signal of the vehicle 1000. In this way, the passenger can be reminded to adjust the inclination angle of the toilet bowl 201 according to the vehicle speed, and the sitting posture of the passenger can be changed by adjusting the inclination angle of the toilet bowl 201 to avoid the injury caused by the collision of the vehicle 1000 to the greatest extent.

[0054] Further, after the vehicle 1000 starts and runs, the controller determines the state of the seat basin 201. If the controller determines that the seat basin 201 is in a large inclination state, the controller sends an instruction to the vehicle computer. The vehicle computer system can remind the passengers in the vehicle of the state of the seat 200 and remind the passengers to adjust the seat basin 201 to the normal state. If the passengers in the vehicle lower the seat basin 201 to the normal state, the controller sends an instruction to the vehicle computer to control the vehicle computer to stop reminding the passengers in the vehicle.

[0055] According to some embodiments of the present invention, after the vehicle computer first reminds the passengers, if the inclination angle of the seat basin 201 still has not returned to the normal state, the controller receives the vehicle speed signal again after a preset period of time. If the controller receives a non-zero vehicle speed signal that does not exceed the first vehicle speed, the controller determines the inclination angle of the seat basin 201. If the inclination angle of the seat basin 201 has not returned to the normal state, the controller sends an instruction to the vehicle computer to remind the passengers to adjust the inclination angle of the seat basin 201. At this time, the adjustable range of the inclination angle of the seat basin 201 is not limited. Among them, the first vehicle speed in the embodiments of the present invention can be 30 km / h.

[0056] According to some other embodiments of the present invention, after the vehicle computer first reminds the passengers, if the inclination angle of the seat basin 201 still has not returned to the normal state, the controller receives the vehicle speed signal again after a preset period of time. If the controller receives a non-zero vehicle speed signal that is between the first vehicle speed and the second vehicle speed, the controller determines the inclination angle of the seat basin 201. If the inclination angle of the seat basin 201 has not returned to the normal state, the controller sends an instruction to the vehicle computer to remind the passengers to adjust the inclination angle of the seat basin 201. At the same time, the controller sends an instruction to the driving member 51 to control the driving member 51 to adjust the inclination angle of the seat basin 201 to the first preset angle. Among them, the second vehicle speed in the embodiments of the present invention can be 65 km / h, and the range of the first preset angle is between 0 - 30°.

[0057] According to still some other embodiments of the present invention, after the vehicle computer first reminds the passengers, if the inclination angle of the seat basin 201 still has not returned to the normal state, the controller receives the vehicle speed signal again after a preset period of time. If the controller receives a non-zero vehicle speed signal that is between the second vehicle speed and the third vehicle speed, the controller determines the inclination angle of the seat basin 201. If the inclination angle of the seat basin 201 has not returned to the normal state, the controller sends an instruction to the vehicle computer to remind the passengers to adjust the inclination angle of the seat basin 201. At the same time, the controller sends an instruction to the driving member 51 to control the driving member 51 to adjust the inclination angle of the seat basin 201 to the second preset angle. Among them, the third vehicle speed in the embodiments of the present invention can be 80 km / h, and the range of the second preset angle is between 0 - 20°.

[0058] According to some further embodiments of the present utility model, after the vehicle machine first reminds the occupant, if the inclination angle of the seat pan 201 still has not been restored to the normal state, the controller receives the vehicle speed signal again after a preset period of time. If the vehicle speed signal received by the controller is not zero and is the third vehicle speed, the controller judges the inclination angle of the seat pan 201. If the seat pan 201 has not been restored to the normal state, the controller issues an instruction to the vehicle machine to remind the person to adjust the inclination angle of the seat pan 201. At the same time, the controller issues an instruction to the driving member 51 to control the driving member 51 to adjust the inclination angle of the seat pan 201 to a third preset angle. Wherein, the range of the third preset angle is between 0-10°.

[0059] It should be noted that, in the embodiments of the present utility model, the preset time can be set to 10 min. As the vehicle speed increases, the driving safety of the vehicle 1000 decreases accordingly. Such a setting is to remind the passengers to pay attention to restoring the normal seat 200 when the vehicle 1000 is driving at a high speed, so as to reduce the injury suffered by the personnel when the vehicle 1000 suddenly collides.

[0060] When the controller judges that the vehicle 1000 is turned off and the seat pan 201 is in a large inclination state, the controller can send an instruction to the driving member 51 to control the driving member 51 to drive the front end of the first support member 20 to descend until the seat pan 201 is restored to the normal state, which can facilitate the vehicle occupants to get off the vehicle.

[0061] According to the embodiments of the present utility model, the controller is connected to the vehicle machine and references the braking signal of the automatic emergency braking system of the vehicle 1000. When the controller receives the braking signal of the automatic emergency braking system of the vehicle 1000, the generator body in the generator triggers expansion, and the powerful thrust generated in the generator can quickly push the driving member 51 backward, thereby enabling the front end of the first support member 20 to quickly descend, so that the seat pan 20 can quickly return to the normal state, thereby avoiding the human body being collided in the posture of the large inclination state of the seat pan 201 and reducing the injury suffered by the personnel.

[0062] According to the embodiments of the present utility model, the seat adjusting device 100 can be applied to the vehicle 1000.
