Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing, specifically to a double folding seat and an automobile. Background Technology
[0002] With the increasing popularity of automobiles, especially commercial vehicles, the conflict between the rear seat seating function and cargo loading space has become prominent. Therefore, the design and application of a seat that can adequately meet passenger needs while also folding down to maximize loading space when needed is essential. Currently, there are various types of folding seats on the market: some are designed to fold forward, which can free up some interior space, but because the frame doesn't fold, the overall volume after folding is still relatively large, resulting in low utilization of longitudinal space and failing to solve the problem of loading extra-long items; some can also fold sideways, but either they prioritize conventional seating reliability at the expense of ease of operation, or they overemphasize ease of operation while neglecting the seat's inherent seating function; or the fit between the folded seat and the vehicle body is not tight enough, affecting the maximization of space or the dynamic stability after folding. This is because forward-folding seats still occupy a significant amount of floor space after folding, which is not conducive to loading long, large items; while some side-folding seats emphasize seating performance but cannot guarantee a minimized overall volume after folding, leaving room for optimization. Utility Model Content
[0003] To solve the above problems, this utility model proposes a double-person folding seat and a car thereof. The specific technical solution is as follows: A double folding seat, installed in a vehicle body, includes a seat cushion, a backrest, a first folding mechanism, a support leg, a support plate, and a second rotating shaft. The backrest is connected to the side of the seat cushion facing away from the vehicle body via the first folding mechanism, which folds the backrest towards the seat cushion. One end of the support leg is connected to the vehicle body's bottom plate, and the other end is connected to the side of the seat cushion facing the vehicle body's bottom plate via the second rotating shaft. The seat cushion rotates around the second rotating shaft to fold towards the side wall of the vehicle body. One end of the support plate is detachably connected to the vehicle body's bottom plate, and the other end is movably connected to the side of the seat cushion facing the vehicle body's bottom plate.
[0004] Furthermore, the first folding mechanism includes a first rotating shaft, an adjuster, and a folding pull cord. The seat back is connected to the seat cushion via the first rotating shaft. The seat back can rotate around the first rotating shaft and fold towards the seat cushion. One end of the first rotating shaft is connected to the adjuster, and the end of the adjuster away from the first rotating shaft is connected to the folding pull cord.
[0005] Furthermore, the side wall of the support foot is connected to a mounting foot plate, the mounting foot plate being parallel to the bottom plate of the vehicle body, and the mounting foot plate being threadedly connected to the bottom plate of the vehicle body.
[0006] Furthermore, the support plate is connected to a meshing assembly at one end near the bottom plate of the vehicle body. The bottom plate of the vehicle body is recessed to form a meshing groove, and a meshing shaft is connected to the side wall opposite the meshing groove. The support plate is fixed to the bottom plate of the vehicle body by meshing the meshing shaft through the meshing assembly.
[0007] Furthermore, the engagement assembly includes an engagement tooth lock and an unlocking handle. The end of the support plate near the bottom plate of the vehicle body is connected to the openable and closable engagement tooth lock. The side wall of the support plate is connected to the unlocking handle, which is used to control the opening and closing of the engagement tooth lock. When the engagement tooth lock is closed, the engagement tooth lock engages the engagement shaft.
[0008] Furthermore, the seat cushion has an inwardly recessed groove on the side facing the bottom plate of the vehicle body. A third rotating shaft is connected to the opposite side wall of the groove. The support plate is connected to the groove through the third rotating shaft. The support plate can rotate around the third rotating shaft and be accommodated in the groove.
[0009] Furthermore, tension springs are connected to opposite ends of the third rotating shaft. When the support plate is folded into the receiving groove along the third rotating shaft, the tension springs are used to fix the support plate in the receiving groove.
[0010] Furthermore, the seat cushion is provided with a restraint assembly, which includes a restraint ring, a restraint strap, and a receiving bag. One end of the restraint strap is fixedly connected to the receiving bag, and the restraint strap is received in the receiving bag. A restraint ring is fixedly connected to the side wall of the vehicle body. When the folding seat is folded along the second rotation axis, the restraint strap is taken out from the receiving bag, and the other end of the restraint strap passes through the restraint ring and the restraint ring to fix the folding seat to the side wall of the vehicle body.
[0011] Furthermore, a support block is provided on the seat back. When the seat back is folded towards the seat cushion, the support block is located on the side of the seat back facing the seat cushion. A rubber layer is connected to the side wall of the vehicle body. When the seat cushion is folded towards the side wall of the vehicle body, the support block abuts against the rubber layer.
[0012] This utility model also provides a car equipped with the aforementioned double folding seat.
[0013] This utility model of a vehicle double seat folding mechanism has the following beneficial effects: the seat back and seat cushion on the seat body are shaped to match the contact surfaces, ensuring that the seat cushion and seat back can be completely flattened when folded, which not only improves the neatness of the appearance after folding, but also minimizes the folding thickness and maximizes the utilization of Y-direction space; the interlocking headrest can be partially retracted into the seat back area, further improving the neatness of the appearance after folding, while also contributing some X-direction space; the support plate receiving groove can be well embedded in when the fixed support plate is folded up, which not only prevents the support plate from protruding outward and causing injury to the occupants of the vehicle, but also reduces the occupation of Y-direction space by the outward protrusion of the support plate; the design of seat back folding cable and unlocking handle makes unlocking easy. Meanwhile, the unlocking handle is located inside the folding support plate, effectively optimizing the appearance and workmanship; the closed flat carpet structure design improves the carpet's sealing, preventing gaps in the floor mat that could lead to dust accumulation, debris buildup, and water accumulation on the car floor, facilitating cleaning, ensuring a clean interior, and effectively reducing the risk of rust from water accumulation on the car floor; the side restraint ring in the body side restraint assembly adopts a low-position design, ensuring that the restraint straps partially wrap around the seat, increasing the contact area between the restraint straps and the seat, thereby improving the dynamic stability when the seat is upright; the webbing uses a high-damping thickened material, combined with a thick matte tensioning and locking mechanism body, ensuring good durability and resistance to deformation; the coarse-toothed locking teeth cooperate well with the high-damping restraint, ensuring sufficient locking force; the locking teeth are pressed by a torsion spring, providing good clamping force durability, and the push-to-unlock mechanism allows for easy operation with a single finger. The body-mounted support block is made of hard rubber material and is fixed to the back of the backrest and encased in the backrest material. When it is attached to the inner side panel of the body, the soft fabric comes into direct contact with the hard metal body without scratching the body. At the same time, the rubber block with a certain degree of hardness ensures both a certain degree of support rigidity and a tight fit. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please refer to Figure 1 Up to 7, this embodiment provides a double-person folding seat mechanism, including a seat back body 10, a seat cushion body 20, a fixed support body 30, a folding support plate body 40, a locking bolt body 50, a vehicle side restraint ring 60, a vehicle side leaning support body 70, and a vehicle floor 80.
[0017] The seat back body 10 is movably connected to the seat cushion body 20 via a backrest rotation shaft 14 and a backrest angle adjuster, forming a cushion assembly. The fixed support foot body 30 and the folding support plate body 40 are movably connected to the seat cushion body 20 via a fixed support foot rotation shaft 32 and a folding support plate rotation shaft 41, respectively, forming a side-folding seat assembly together with the cushion assembly. The side-folding seat assembly is rigidly connected to the vehicle floor plate via bolts through holes in the fixed support foot mounting plate 31 at the fixed support foot body 30 end. The folding support plate body 40 is engaged with the locking pin 51 on the locking bolt body 50 via a seat lock 44 on it. Furthermore, the locking bolt body 50 is rigidly connected to the vehicle floor plate 80 via bolts, ensuring that both ends of the lower part of the side-folding seat assembly are connected and fixed to the vehicle body, realizing the seating function of the seat.
[0018] When the side-flipping function is required, the backrest folding rope 13 located at the rear end of the angle adjuster 12 is pulled by hand, and the seat back body 10 is pushed towards the seat cushion body 20 from the backrest. The backrest body rotates around the backrest rotation axis 14 to achieve the folding of the backrest body and the seat cushion body. Then, the unlocking handle 45 located inside the folding support plate body 40 is pushed upward by the finger, and the seat is lifted upward on the side close to the folding support plate body. The seat lock 44 disengages from the locking pin 51 and engages to achieve the unlocking function. The seat is further pushed to the side and upward around the fixed support foot rotation axis 32 towards the side of the vehicle until it is close to the upright position (approximately 90 degrees to the vehicle floor). At this time, the front and rear ends of the upper side of the fixed support foot contact the fixed support foot rotation limit block 33 to limit the lower part of the side-flipping angle. At the same time, the vehicle body abutment support block 15 located at the rear of the backrest body 10 contacts the vehicle body side abutment support body 70 to achieve the middle limit and support. Push the folding support plate body 40 from the outside to the inside by hand, so that the folding support plate body 40 rotates around the folding support plate rotation axis 41 until it is embedded in the support plate receiving groove 22 at the bottom of the seat cushion body 20, thus realizing the folding function of the support plate. Take out the excess part of the restraint strap assembly 23 from the restraint strap receiving bag 25 on the side of the seat cushion body 20, pass it through the body side restraint ring 60 fixed to the side of the vehicle body, wrap it back, and then pass it into the metal buckle of the restraint strap assembly 23 and tighten it to realize the side-folding function of the entire side-folding seat.
[0019] The folding surfaces of the seat back body 10 and the seat cushion body 20 are designed to fit together more flatly and squarely when folded, minimizing the volume after folding. The interventional headrest 11 set on the seat back body 10 adopts an interventional design. After the backrest and seat cushion are folded, pressing the interventional headrest can insert the headrest part into the projection area of the backrest, avoiding the headrest protruding from the seat and occupying too much space in the X direction of the vehicle.
[0020] The vehicle body abutment support block 15 is set on the back frame of the seat back body 10 to ensure a certain support strength. The vehicle body abutment support block 15 is hidden inside the back material to avoid affecting the appearance. At the same time, the material of the vehicle body abutment support block 15 is a rubber material with moderate softness and hardness, which can achieve reliable support and buffering between the contact with the vehicle body support body 70 and is not easy to damage the vehicle body.
[0021] The two ends of the seat cushion body 20 are respectively connected to the fixed support foot body 30 and the folding support plate body 40 through the fixed support foot rotation shaft 32 and the folding support plate rotation shaft 41, so as to realize the flexible switching between the upper part of the seat in the sitting function and the flip-folding function.
[0022] The seat cushion body 20 has a concave space at the bottom of the end near the folding support plate body 40. This is the support plate receiving groove 22. The size of the space in the support plate receiving groove 22 is similar to the outer size of the folding support plate body 40. When the folding support plate body 40 is folded inward, it can be accommodated in the groove. This ensures that the outer surface of the folding support plate body 40 is basically flush with the lower surface of the seat cushion body 20 after folding. This improves the neatness of the appearance after folding and the space utilization rate. It also avoids the impact of the outward protrusion of the folding support plate 40 on the movement of people in the vehicle and possible injury.
[0023] One folding support plate tension spring 42 is provided at the front and rear of the movable connection between the folding support plate body 40 and the seat cushion body 20. One end of the folding support plate tension spring 42 is fastened to the seat cushion frame 21, and the other end is fastened to the folding support plate body 40. When the folding support plate body 40 is folded into the support plate receiving groove 22, the folding support plate tension spring 42 constrains the folding support plate body 40 through tension force, so as to avoid the folding support plate body 40 from loosening and causing problems such as dynamic vibration and abnormal noise. When it is necessary to open the folding support plate body 40, simply pull it outward by hand to release the constraint force of the folding support plate tension spring 42.
[0024] A seat end restraint ring 24 is welded to one side of the seat cushion frame 21 near the folding support plate body 40. One end of the restraint strap assembly 23 is secured to the seat end restraint ring 24. When the seat is in the seating function, the excess portion of the restraint strap assembly 23 can be inserted into the restraint strap receiving bag 25 sewn onto the fabric of the seat cushion body 20. The vehicle side restraint ring 60 is fixed to the inner panel of the vehicle side by rivets. Its X-axis coordinate is basically flush with the seat end restraint ring 24. When the seat is folded and its upper part needs to be restrained to the vehicle body, the excess portion of the restraint strap assembly 23 is pulled out from the restraint strap receiving bag 25, passed through the vehicle side restraint ring 60, and then looped back through the metal buckle on the restraint strap assembly 23 to tighten it.
[0025] The restraint strap assembly 23 uses a thickened, high-strength composite woven material, providing high restraint strength. Its high-damping surface better engages with the locking mechanism, reducing the risk of slippage and ensuring reliable restraint of the high-center-of-gravity, high-mass double chair after a rollover. The locking mechanism of the restraint strap assembly 23 employs thick, durable, coarse-toothed locking teeth, which work in conjunction with the high-damping restraint strap material to generate sufficient locking force, ensuring reliable restraint. The locking teeth on the restraint strap assembly 23 are spring-loaded; to release the restraint force, simply press the locking teeth with your finger to automatically loosen the restraint strap, which can then be pulled out from the side restraint ring 60 of the vehicle body.
[0026] This embodiment also provides a car, which includes the above-described double folding seat mechanism.
[0027] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
