[0032] It should be noted that, in the following embodiments, the “first”, “second” and “third” mentioned do not represent an absolute distinction in structure and / or function, nor do they represent a sequence of execution, but are merely for the convenience of description.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0034] Embodiment 1
[0035] First, as Figures 1 to 4 As shown, an embodiment of the present invention provides a seat system, including a seat rail 10, a seat body 11 arranged on the seat rail 10 and an adjusting device for adjusting the angle of the seat body 11, the adjusting device includes an electromagnetic damper 9 connected to the seat rail 10, and a plurality of electromagnetic dampers 9 are arranged.
[0036] Specifically, the seat system provided by the embodiment of the present invention can adjust the state of the seat in real time according to the changes in the body posture, so that the occupant always remains parallel to the ground, ensuring a comfortable sitting posture for the passenger, avoiding the body being fixed by the seat belt, and greatly improving the riding comfort; and the control system of the intelligent seat system is integrated in the vehicle system, and the control system can read the body posture signal and the vibration signal of the vibration collector in the electromagnetic damper 9. At the same time, the system can also be linked with the music function to control the electromagnetic damper 9 to move according to the rhythm of the music. This seat system also takes into account the playability of off-roading, and can link the seat with the music to formulate three modes, so that the seat can sway with the rhythm of the music.
[0037] like Figure 1 and Figure 2 As shown, the electromagnetic damper 9 includes an upper support 12, a lower support 14 and a sliding damping rod 13 disposed on the lower support 14 and connected to the upper support 12, and the upper support 12 is connected to the seat rail 10. The lower support 14 is integrated with a vibration signal collector.
[0038] As a preferred example, Figure 1 and Figure 2 As shown, the upper end of the sliding damping rod 13 is connected to the upper support 12 through a ball joint. The upper support 127 of the electromagnetic damper 9 is connected to the lower side of the seat rail 10 through bolts; the lower support 149 of the electromagnetic damper 9 is connected to the vehicle body floor through bolts; the electromagnetic damper 9 is installed between the seat rail 10 and the vehicle body floor.
[0039] like Figure 1 As shown, two seat rails 10 are provided, an electromagnetic damper 9 is provided below each of the two seat rails 10 , and two electromagnetic dampers 9 are provided below the seat rails 10 .
[0040] like Figure 1 As shown, the electromagnetic damper 9 is installed between the seat rail 10 and the vehicle body floor. By adjusting the electromagnetic damper 9 in real time, it generates a reverse excitation to offset the vibration response of the road excitation to the seat body 11 through the vehicle body, thereby improving driving comfort. The real-time adjustment movement of the electromagnetic damper 9 is controlled by the control system. The specific control process is as follows Figure 3 When the vehicle body posture changes significantly during off-road driving, the control system controls the electromagnetic damper 9 to adjust the angle of the seat body 11 so that the passenger can maintain a sitting posture parallel to the ground, avoiding discomfort caused by being fastened to the seat by the seat belt. The specific control flow chart is as follows: Figure 4At the same time, a comfortable riding posture can provide a better field of vision, which is conducive to enjoying the beautiful scenery during off-road travel and greatly improves riding comfort. It should be emphasized here that this function is only applicable to seats other than the driver's seat, because when the body posture changes significantly, if the passenger is required to maintain a sitting posture parallel to the ground, the seat will have a large displacement and angle, and a large change in the seat will affect the driver's control of the vehicle, such as not being able to step on the accelerator pedal, brake, etc.
[0041] The seat system provided by the embodiment of the present invention has a linkage function with music - self-hi mode, which divides all music into three types, corresponding to the three modes defined by the intelligent seat system as soothing, cheerful and explosive. According to different types of music rhythm, the control system automatically identifies the corresponding mode, and then adjusts the four electromagnetic dampers 9 to move up and down with the rhythm of the music through the control system. At this time, the passengers can twist or shake their bodies with the music according to the movement rhythm of the seat.
[0042] The seat system of the above structure has the following advantages:
[0043] 1. Effectively filter the vibration caused by complex road excitation when the off-road vehicle passes through unpaved roads, improving comfort;
[0044] 2. By adjusting the damping rod in real time, the seat is always kept parallel to the ground, ensuring a comfortable sitting posture for passengers and preventing the seat belt from fixing the body, which greatly improves riding comfort;
[0045] 3. The linkage mode between seats and music greatly increases the novelty and playability of the vehicle;
[0046] 4. It can replace the seat lifting function and reduce the cost of seat lifting motor and other components.
[0047] In a second aspect, an embodiment of the present invention further provides a vehicle, including a seat system of the above structure. The specific structure of the seat system can be referred to Figure 1 to Figure 2 Since the vehicle of the present invention includes the seat system in the above embodiment, it has all the advantages of the above seat system.
[0048] Embodiment 2
[0049] In the seat system provided by an embodiment of the present invention, the seat headrest includes a headrest body 1 arranged on a sliding mechanism, a guide mechanism arranged on the headrest body 1, a limit member 6 arranged on the sliding mechanism, and a gravity ball 7 movably arranged on the guide mechanism for limiting the limit member 6 when the headrest body 1 is in the first position. The gravity ball 7 is arranged to be separated from the limit member 6 so that the headrest body 1 can move downward from the first position to the second position.
[0050] like Figure 5 and Figure 6 As shown, the sliding mechanism mainly includes a guide rod 3 and a fixed base 2, a stopper 6 is installed on the fixed base 2, the seat body includes a seat and a backrest arranged on the seat, the seat is installed on the seat rail 10, the fixed base 2 is installed on the backrest of the seat body, the fixed base 2 is sleeved on the guide rod 3, the guide rod 3 is fixedly connected to the headrest body 1, the headrest body 1 is used for the head of the occupant in the car to lean on, when the headrest body 1 moves relative to the fixed base 2, the headrest body 1 can adjust the distance between the headrest body 1 and the backrest of the seat body, in this process, the headrest body 1 drives the guide rod 3 to slide on the fixed base 2. The distance between the headrest body 1 and the backrest of the seat body in the first position is greater than the distance between the headrest body 1 and the backrest of the seat body in the second position.
[0051] like Figures 5 to 12 As shown, a guide groove 8 for guiding the gravity ball 7 to move is provided on the guide mechanism. The guide groove 8 is V-shaped, and includes a first groove and a second groove. The first groove and the second groove are connected, and there is an angle between the length direction of the first groove and the length direction of the second groove, and the angle is an obtuse angle. The first groove is located between the second groove and the headrest body 1. When the headrest body 1 is in the first position, the gravity ball 7 is located in the first groove, and the gravity ball 7 contacts the top of the stopper 6, which can prevent the headrest body 1 from moving downward, so that the headrest body 1 remains in the first position; when the backrest tilts backward, the gravity ball 7 can roll from the first groove to the second groove, and the gravity ball 7 is separated from the top of the stopper 6. At this time, the stopper 6 cannot prevent the headrest body 1 from moving downward, and the headrest body 1 can move downward under the action of its own gravity, and the headrest body 1 automatically moves from the first position (the headrest body 1 at this position is in an unlocked state) to the second position.
[0052] like Figures 5 to 12 As shown, the guide mechanism includes a guide element 4, which is connected to the headrest body 1, and a guide groove 8 is provided on the guide element 4. The guide element 4 is a V-shaped structure in the interior. The guide element 4 includes a first guide section and a second guide section, and there is an angle between the length direction of the first guide section and the length direction of the second guide section, and the angle is an obtuse angle, and the first guide section is located between the second guide section and the headrest body 1. One end of the first guide section in the length direction is fixedly connected to the headrest body 1, and the other end of the first guide section in the length direction is fixedly connected to one end of the second guide section in the length direction, and the other end of the second guide section in the length direction is a closed end, the first groove is provided inside the first guide section and the first groove extends along the entire length direction of the first guide section, the second groove is provided inside the second guide section and the second groove extends along the length direction of the second guide section, and the second guide section extends obliquely toward the rear and upper side of the first guide section.
[0053] Preferably, the headrest body 1 and the guide element 4 are both made of plastic, and the headrest body 1 and the guide element 4 are integrally injection-molded, which is convenient to process and low in cost.
[0054] like Figures 5 to 12 As shown, the guide mechanism also includes a cover plate 5 disposed on the guide element 4 and used to limit the gravity ball 7, and the cover plate 5 is tightly matched with the guide element 4. An opening is provided at one end of the guide element 4 in the width direction (the width direction of the guide element 4 is parallel to the length direction of the headrest body 1, and is vertical to the length direction of the guide rod 3 in space), and the other end of the guide element 4 in the width direction is a closed end. The cover plate 5 is used to close the open end of the guide element 4, so that the gravity ball 7 is kept in the guide groove 8, to prevent the gravity ball 7 from falling off, to improve reliability, and to facilitate installation. In addition, in the width direction, the gap between the gravity ball 7 and the closed end of the cover plate 5 and the guide element 4 is relatively small, so that the gravity ball 7 can accurately match the limiter 6.
[0055] like Figures 5 to 12 As shown, the cover plate 5 includes a first limiting portion and a second limiting portion connected to each other, the second limiting portion is embedded in the guide groove 8, the first limiting portion is located outside the guide element 4, the first limiting portion is used to control the depth of the second limiting portion inserted into the guide groove 8, and the second limiting portion faces the closed end in the width direction of the guide element 4.
[0056] like Figures 5 to 12As shown, the first limiting portion and the second limiting portion are V-shaped structures. The first limiting portion includes a first front limiting section 501 and a first rear limiting section 502. There is an angle between the length direction of the first front limiting section 501 and the length direction of the first rear limiting section 502, and the angle is an obtuse angle. The angle between the length direction of the first front limiting section 501 and the length direction of the first rear limiting section 502 is the same as the angle between the length direction of the first guide section and the length direction of the second guide section. The first front limiting section 501 is located between the first rear limiting section 502 and the headrest body 1. The cover plate 5 is installed on the guide element 4. The first front limiting section 501 is in contact with the surface of the first guide section and the length directions of the two are parallel. The first rear limiting section 502 is in contact with the surface of the second guide section and the length directions of the two are parallel. The second limiting portion includes a second front limiting section 503 and a second rear limiting section 504. The length direction of the second front limiting section 503 and the length direction of the second rear limiting section 504 have an angle, and the angle is an obtuse angle. The size of the angle between the length direction of the second front limiting section 503 and the length direction of the second rear limiting section 504 is the same as the size of the angle between the length direction of the first guide section and the length direction of the second guide section. The cover plate 5 is installed on the guide element 4, the second front limiting section 503 is embedded in the first groove, and the second rear limiting section 504 is embedded in the second groove. The length direction of the second front limiting section 503 is parallel to the length direction of the first front limiting section 501, and the length of the second front limiting section 503 is less than the length of the first front limiting section 501. The length direction of the second rear limiting section 504 is parallel to the length direction of the first rear limiting section 502, and the length of the second rear limiting section 504 is less than the length of the first rear limiting section 502. The width of the second front limiting section 503 is smaller than that of the first front limiting section 501, and the width of the second rear limiting section 504 is smaller than that of the first rear limiting section 502. The widths of the first front limiting section 501 and the first rear limiting section 502 are the same, the widths of the second front limiting section 503 and the second rear limiting section 504 are the same, the width direction of the first front limiting section 501 is perpendicular to the length direction and thickness direction of the first front limiting section 501, the width direction of the first rear limiting section 502 is perpendicular to the length direction and thickness direction of the first rear limiting section 502, the width direction of the second front limiting section 503 is perpendicular to the length direction and thickness direction of the second front limiting section 503, and the width direction of the second rear limiting section 504 is perpendicular to the length direction and thickness direction of the second rear limiting section 504. The thickness directions of the first front limiting section 501, the first rear limiting section 502, the second front limiting section 503 and the second rear limiting section 504 are parallel to the thickness direction of the cover plate 5, and the first limiting portion and the second limiting portion are arranged in sequence along the thickness direction of the cover plate 5, and the thickness direction of the cover plate 5 is parallel to the length direction of the headrest body 1.
[0057] like Figures 5 to 12As shown, the cover plate 5 also includes a third limiting portion 505 connected to the second limiting portion, the third limiting portion 505 is embedded in the guide groove 8, the third limiting portion 505 is located between the gravity ball 7 and the headrest body 1, and the second limiting portion is located between the third limiting portion 505 and the first limiting portion. The third limiting portion 505 is fixedly connected to the second front limiting section 503, and the third limiting portion 505 is inserted into the first groove. The third limiting portion 505 is used to limit the initial position of the gravity ball 7. When the headrest body 1 is in the first position, the gravity ball 7 is in contact with the third limiting portion 505, and the third limiting portion 505 prevents the gravity ball 7 from rolling toward the position of the headrest body 1, ensuring that the gravity ball 7 and the limiting member 6 always maintain a contact state.
[0058] like Figures 5 to 8 and Fig.11 As shown, the limiting member 6 is fixedly arranged on the top of the fixed base 2, and an avoidance hole is arranged on the guide element 4 for the limiting member 6 to pass through. After passing through the avoidance hole, the limiting member 6 can contact the gravity ball 7 in the upper guide groove 8.
[0059] When the seat is unfolded, the backrest and the headrest tilt backwards, and the gravity ball 7 rolls from the first groove toward the second groove. After the gravity ball 7 is separated from the top of the limiter 6, the limiter 6 cannot prevent the headrest body 1 from moving downward. The headrest body 1 can move downward under the action of its own gravity. The headrest body 1 automatically moves from the first position to the second position, and the limiter 6 passes upward through the avoidance hole.
[0060] Through the cooperation of the cover plate 5 and the guide element 4 and the gravity ball 7 and the stopper 6 of the above structure, the downward adjustment stroke of the headrest position can be increased. This automatic adaptability improves the comfort and convenience of the passengers, and there is no need to manually adjust the position of the headrest. In addition, this implementation method has a simple structure and is easy to process, which can reduce costs. By accurately designing the shape of the guide groove 8 and the cover plate 5, the accurate cooperation between the gravity ball 7 and the stopper 6 is ensured. This precise control makes the conversion of the headrest between different positions smoother and more reliable.
[0061] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
