Description

Technical Field

[0001] The present invention relates to the technical field of vehicle seats, and more particularly, to a vehicle seat and a leg rest adjusting mechanism thereof. Background Art

[0002] Vehicle seats provide a comfortable and safe sitting posture environment for drivers and passengers, and are an important part of the interior of a vehicle. With the continuous development of the automotive industry, seat design no longer only focuses on basic sitting comfort, but also involves multiple aspects such as safety, ergonomics, appearance design, and material use. There are still some deficiencies in existing vehicle seats.

[0003] For example, the invention patent with the publication number CN110857041B discloses a vehicle seat and an adjusting mechanism thereof, including a base and an unlocking component. The base is in an arc-shaped long strip shape, and a chute is provided on the front end surface of the base; one end of the unlocking component is installed in the chute, and the other end is located outside the base. Pulling the other end of the unlocking component causes the unlocking component to move left and right along the chute; a plurality of uniformly arranged limiting parts are provided on the upper and lower inner wall surfaces of the chute, and a limiting piece is provided at one end of the unlocking component; when one end of the unlocking component moves to a position corresponding to the limiting part, the limiting piece and the limiting part are in a locked state; when one end of the unlocking component moves away from the position corresponding to the limiting part, the limiting piece and the limiting part are in an unlocked state. The angle of the vehicle seat backrest can be adjusted personalized according to different needs of customers. Its structure is simple, the adjustment is convenient, and it is safe and reliable, which can effectively improve the riding comfort and user-friendly needs of users.

[0017] The working principle and beneficial effects of the present invention are as follows:

[0018] 1. By arranging the scroll spring, the first traction steel cable and the electric push rod, since the winding direction of the scroll spring from the inside to the outside is opposite to the winding direction of the first traction steel cable, when the electric push rod shortens, the first traction steel cable will gradually wind around the rotating shaft, and the scroll spring will gradually contract from the stretched state, so that the second connection block on the device will automatically unfold, and then the function of automatically unfolding the leg rest is realized. During the unfolding process of the leg rest, the fourth connection block on the electric push rod will also pull the second traction steel cable, and then pull the outer frame and the leg rest as a whole to move backward, so as to realize the function of automatically moving the seat backward when the leg rest unfolds, making full use of the interior space of the vehicle, ensuring the comfort during use, and solving the problem that the front space becomes narrow after the existing seat leg rest is unfolded.

[0019] 2. The device is provided with a rotating shaft, a scroll spring and a rotating plate. The leg rest of the device is gradually unfolded by the pulling force of the scroll spring. The initial state of the scroll spring is in a stretched state. When the scroll spring gradually contracts, the leg rest is gradually unfolded and the pressure on the leg gradually increases as the degree of unfolding increases, thereby realizing the functions of buffering and protection, and solving the problem that the existing leg rest of an automobile seat cannot gradually increase the pulling force during the adjustment process.

[0020] 3. The device is provided with an adjusting component. By rotating the screw rod on the adjusting component, the initial position of the end of the second traction steel rope can be adjusted, thereby changing the initial positions of the outer frame and the seat cushion. The device can retain the function of automatically moving the seat backward when the leg rest is unfolded, and can also change the initial position of the seat, enhancing the adaptability of the device.

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0041] Embodiment 1, as shown in Figures 1 - 17As shown in the figure, this embodiment proposes an automobile seat and its leg rest adjustment mechanism, including an outer frame 1 and a fixing plate 17. The outer frame 1 is slidably installed on the fixing plate 17, and the outer frame 1 can slide on the fixing plate 17. The fixing plate 17 is fixed to the vehicle body and remains stationary. A seat cushion 2 is installed in the middle of the outer frame 1. A first connecting block 3 is installed on the outer frame 1, and a second connecting block 4 is fixedly connected to the first connecting block 3. A support assembly 6 is installed between the first connecting block 3 and the second connecting block 4. The support assembly 6 includes a rotating shaft 605 rotatably installed on the first connecting block 3. A scroll spring 7 is fixedly connected to the outside of the rotating shaft 605. A rotating plate 602 is fixedly arranged on the outside of the scroll spring 7. A first fixing block 604 is slidably arranged in the rotating plate 602. The first fixing block 604 is fixedly connected to the second connecting block 4. A second fixing block 9 is connected to the second connecting block 4. A first leg rest 12 is fixedly arranged on the second fixing block 9. A connecting frame 13 is slidably installed on the first leg rest 12. A second leg rest 16 is slidably arranged on the connecting frame 13. An electric push rod 11 is fixedly arranged on the first connecting block 3. A fourth connecting block 21 is connected to the electric push rod 11. A fixing rod 20 is welded to the fourth connecting block 21. A first traction steel cable 8 is connected between the fixing rod 20 and the rotating shaft 605. A contraction assembly 19 is installed on the outer frame 1. The contraction assembly 19 includes a second traction steel cable 1903 and a first spring 1904 fixedly connected to the outer frame 1. A third fixing block 1902 is fixedly arranged on the first spring 1904. The third fixing block 1902 is fixedly connected to the fixing plate 17. The end of the second traction steel cable 1903 is connected to an adapter block 1905. The adapter block 1905 is connected to the fixing rod 20. When the electric push rod 11 on the device shortens, it will pull the second traction steel cable 1903, and the second traction steel cable 1903 will pull the outer frame 1 to slide on the fixing plate 17, changing the initial position of the outer frame 1. At the same time, as the electric push rod 11 shortens, the first traction steel cable 8 will gradually slacken, so that Figure 14 and Figure 17 the rotating shaft 605 in it rotates clockwise, and the stretched scroll spring 7 gradually contracts, thus gradually driving the rotating plate 602 to rotate clockwise. When the rotating plate 602 rotates clockwise, it will drive the first fixing block 604 to rotate clockwise, and the bent second connecting block 4 gradually unfolds, and the first leg rest 12 and the second leg rest 16 gradually unfold. Furthermore, the device can automatically slide the outer frame 1 and the seat cushion 2 backward while unfolding the leg rest to increase the space at the leg position and make full use of the vehicle interior space. An adjustment assembly 22 is installed on the fixing rod 20. The adjustment assembly 22 is used to adjust the initial position of the adapter block 1905 on the fixing rod 20, thereby adjusting the initial position of the end of the second traction steel cable 1903, and further changing the initial position of the outer frame 1 on the fixing plate 17 to realize the adjustment function of the initial position of the seat.

[0042] Embodiment 2, as Figures 1 - 17As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes an automobile seat and its leg rest adjustment mechanism.

[0043] In this embodiment, a slide bar 10 is fixedly connected to the outer frame 1. The slide bar 10 is slidably installed in the first connection block 3. A first guide plate 601 is fixedly connected to the first connection block 3. The rotating plate 602 is slidably installed outside the first guide plate 601. A third connection block 603 is fixedly arranged on the rotating plate 602. A chute 607 is formed in the rotating plate 602. A slide plate 606 is slidably installed in the chute 607. The slide plate 606 and the first fixed block 604 are fixedly connected. The rotating plate 602 is rotatably connected to the first connection block 3. After the leg rest on the device is unfolded, the position of the first fixed block 604 will change. The first fixed block 604 will drive the slide plate 606 to slide in the chute 607 in the rotating plate 602, so that the leg rest can be stably unfolded and stored.

[0044] In this embodiment, the second connection block 4 is made of rubber material. A groove 5 is formed in the second connection block 4. The groove 5 can close the leg rest after it is unfolded, ensuring the durability of the device, preventing the second connection block 4 from being torn after the leg rest is stored, and extending the service life of the device.

[0045] In this embodiment, the outer wall of the slide plate 606 fits with the inner wall of the chute 607. The second connection block 4, the first fixed block 604 and the slide plate 606 are fixedly connected as an integral structure. When the second connection block 4 rotates, it will drive the first fixed block 604 to rotate synchronously, so as to realize the functions of unfolding and storing the leg rest.

[0046] In this embodiment, the spiral direction of the scroll spring 7 between the rotating shaft 605 and the rotating plate 602 is counterclockwise, and the winding direction of the first traction steel cable 8 on the rotating shaft 605 is clockwise. When Figure 14 the first traction steel cable 8 in it contracts to the left, the scroll spring 7 will gradually change from the stretched state to the contracted state, so as to automatically unfold the leg rest subsequently, and the indirect drive of the leg rest by the scroll spring 7 can ensure the safety of the device during use.

[0047] In this embodiment, damping blocks 14 are fixedly arranged on both the first leg rest 12 and the second leg rest 16. The damping blocks 14 are slidably installed in the connection frame 13. A moving groove 15 is formed in the connection frame 13. The damping blocks 14 cause resistance when the connection frame 13 and the second leg rest 16 slide, so as to change the positions of the connection frame 13 and the second leg rest 16 to adapt to different users.

[0048] In this embodiment, a first limiting plate 18 is fixedly connected to the fixing plate 17. The first limiting plate 18 is slidably installed in the outer frame 1. A guiding block 1901 is fixedly connected to the outer frame 1. The guiding block 1901 is slidably installed in the fixing plate 17. The guiding block 1901 and the first limiting plate 18 can ensure the stable sliding of the outer frame 1 on the fixing plate 17, ensuring the safety of the device during use.

[0049] In this embodiment, the first spring 1904 is sleeved outside the second towing steel cable 1903. There are gaps between the first spring 1904, the outer frame 1 and the first leg rest 12. The outer frame 1 and the fixing plate 17 are in mutual contact. The outer frame 1 is adapted to slide on the fixing plate 17 when the electric push rod 11 shortens. When the second towing steel cable 1903 is pulled, it will cause the outer frame 1 to move on the fixing plate 17, so as to automatically move the seat backward during the subsequent unfolding of the leg rest to increase the leg space, enhancing the practicability of the device.

[0050] In this embodiment, the connecting block 1905 is slidably connected to the fixing rod 20. The second towing steel cable 1903 passes through the inside of the third fixing block 1902. The second towing steel cable 1903 arranged in a penetrating manner can drive the whole seat to move backward when it is pulled, so as to make full use of the space inside the vehicle during the unfolding of the leg rest.

[0051] In this embodiment, the adjusting assembly 22 includes a screw rod 2201 rotatably installed in the fixing rod 20. A guiding groove 2202 is formed in the fixing rod 20. A movable block 2203 is slidably connected in the guiding groove 2202. The movable block 2203 is fixedly connected to the connecting block 1905. The screw rod 2201 is threadedly connected to the movable block 2203. By rotating the screw rod 2201, the movable block 2203 can be made to slide inside the guiding groove 2202, thereby adjusting the initial position of the movable block 2203, which is convenient for subsequent adjustment of the initial position of the seat.

[0052] Specifically, the present invention is an automobile seat and its leg rest adjusting mechanism. First, as Figures 1 - 12 shown, the fixing plate 17 is fixed on the vehicle body and remains stationary. The device can adjust the initial position of the seat as needed. By rotating the screw rod 2201 on the adjusting assembly 22, the movable block 2203 slides inside the guiding groove 2202, thereby pulling the second towing steel cable 1903. The outer frame 1 outside the seat cushion 2 can slide on the fixing plate 17 through the first limiting plate 18 and the guiding block 1901. Therefore, when the second towing steel cable 1903 receives a pulling force, the second towing steel cable 1903 will drive the outer frame 1 to move on the fixing plate 17, thereby adjusting the initial position of the seat.

[0053] As Figures 1 - 11 and Figures 13 - 17As shown, when the electric push rod 11 shortens, the fourth connecting block 21 drives the fixed rod 20 to move, pulling the second traction steel rope 1903. The second traction steel rope 1903 pulls the outer frame 1 to slide on the fixed plate 17, changing the front and back position of the outer frame 1 on the fixed plate 17. At the same time, as the electric push rod 11 shortens, the first traction steel rope 8 will gradually slacken. Since the scroll spring 7 is in a stretched state initially, the slackening of the first traction steel rope 8 will cause Figure 14 and Figure 17 the rotating shaft 605 in them to rotate clockwise, and the stretched scroll spring 7 gradually contracts, thus gradually driving the rotating plate 602 to rotate clockwise. When the rotating plate 602 rotates clockwise, it will drive the first fixing block 604 to rotate clockwise, and the bent second connecting block 4 gradually unfolds, and the first leg rest 12 and the second leg rest 16 gradually unfold. Furthermore, the device can automatically slide the outer frame 1 and the seat cushion 2 backward while unfolding the leg rests, so as to increase the space at the leg position and make full use of the vehicle interior space. Since the device indirectly drives the first leg rest 12 and the second leg rest 16 through the scroll spring 7, the supporting force of the first leg rest 12 and the second leg rest 16 on the legs can be gradually increased, thus realizing the functions of buffering and protection. The device can adjust the initial positions of the connecting frame 13 and the second leg rest 16 through the damping block 14 in the moving groove 15, so as to adapt to different users. After the first leg rest 12 and the second leg rest 16 are unfolded, the position of the first fixing block 604 will change, and the first fixing block 604 will drive the sliding plate 606 to slide in the sliding groove 607 in the rotating plate 602, so that the first leg rest 12 and the second leg rest 16 can be stably unfolded and stored. When the leg rest function of the device is not used, the first connecting block 3 on the outer side of the sliding rod 10 can be slid to remove the whole first connecting block 3 from the outer frame 1.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
