Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle. Background Technology

[0002] With the rapid development of the automotive industry and the diversification of car usage scenarios, cars are no longer just a means of transportation; they also embody changes in human lifestyles, expanding users' time and space in multiple dimensions. To meet multifunctional car usage needs, not only is a reasonable and flexible layout of the interior space required, but also the safety of passengers must be taken into account. Therefore, the layout of vehicle seats and seat belts needs to be flexible and adaptable.

[0003] Currently, the front and rear seat belts in M-class vehicles on the market come in two types: one for the front seat belts located on the B-pillar of the vehicle's side, with the seat belt retractor fixed to the lower end of the B-pillar and a guide ring fixed to the upper end of the B-pillar to separate the seat belt from the seat; and another for the rear seat belts located on the rear wheel arch of the vehicle's side, with the seat belt retractor fixed to a bracket on the wheel arch, the retractor being higher than the seat back without a separate guide ring. It is evident that the existing designs lack installation flexibility, cannot adaptively adjust to the rear seat's adjustment angle, and are prone to seat belt deformation, loosening, or tightening, affecting protective accuracy. Furthermore, traditional anchor points and connecting components are exposed or occupy a significant amount of space inside the seat, limiting rear seat design and making it unsuitable for ultra-thin seats, multi-position adjustable seats, and other new seat structures. The installation process requires precise alignment of multiple fixing holes, relies on specialized tools for positioning, is cumbersome, and is difficult to disassemble for later maintenance. In a collision, the traditional fixing structure has a single force transmission path, easily leading to localized stress concentration, causing anchor points to loosen or seat belts to shift, failing to provide uniform restraint protection for occupants of different body types.

[0043] In this utility model, the mounting plate 4 is further provided with a third mounting groove 11; the third mounting groove 11 is located on the side of the second mounting groove 6 away from the first mounting groove 5.

[0044] The aforementioned seat belt assembly 7 also includes a fixing component 12; the shape of the fixing component 12 matches the shape of the third mounting groove 11; the fixing component 12 is detachably connected to the mounting plate 4 via the third mounting groove 11; the webbing 9 passes through the guide ring 10 and the fixing component 12 in sequence on the side away from the retractor assembly 8.

[0045] In some embodiments, such as Figure 3 As shown, the mounting plate 4 is also provided with a third mounting groove 11, which is located on the side of the second mounting groove 6 away from the first mounting groove 5.

[0046] like Figure 4-5 As shown, the seat belt assembly 7 also includes a fixing component 12. The shape of the fixing component 12 matches the shape of the third mounting groove 11. The fixing component 12 is detachably connected to the mounting plate 4 through the third mounting groove 11, so that the side of the webbing 9 away from the retractor assembly 8 passes through the guide ring 10 and the fixing component 12 in sequence. By setting the third mounting groove and connecting it to the fixing component, it is ensured that the webbing slides along the designed path during a collision, providing stable support for the webbing, preventing displacement or loosening, and improving the restraint effect on the occupant.

[0063] In this utility model, the aforementioned retractor assembly 8 includes a retractor mounting bracket 20 and a retractor 21; the retractor mounting bracket 20 is disposed between the retractor 21 and the mounting plate 4; the side of the retractor mounting bracket 20 closest to the mounting plate 4 is detachably connected to the mounting plate 4; and the side of the retractor mounting bracket 20 closest to the retractor 21 is fixedly connected to the retractor 21.

[0064] In some embodiments, such as Figure 7As shown, to clarify the functional division, the retractor assembly 8 is divided into two parts: a retractor mounting bracket 20 and a retractor 21. The retractor mounting bracket 20 is disposed between the retractor 21 and the mounting plate 4. The side of the retractor mounting bracket 20 closest to the mounting plate 4 is detachably connected to the mounting plate 4, while the side of the retractor 21 bracket closest to the retractor 21 is fixedly connected to the retractor 21; that is, the two are integrally formed. Based on functional characteristics, the retractor assembly is divided into a retractor mounting bracket and a retractor, which are integrally formed. The retractor mounting bracket is used to connect to the mounting plate, thus clarifying the load transfer path.

[0065] In this utility model, the retractor 21 is provided with a reel 22 and a locking mechanism 23 inside; the side of the webbing 9 near the retractor 21 is fixedly connected to the reel 22; the side of the reel 22 is detachably connected to the locking mechanism 23.

[0066] In some embodiments, such as Figure 7 As shown, the retractor 21 internally houses a spool 22 and a locking mechanism 23. The side of the webbing 9 closest to the retractor 21 is fixedly connected to the spool 22, or in other words, the side of the webbing 9 closest to the retractor 21 is wound around the spool 22. The side of the spool 22 is detachably connected to the locking mechanism 23. Specifically, the locking mechanism 23 internally houses a sensing device. The core actuating component of the locking mechanism 23 is a locking pawl. Under normal circumstances, the pawl is held in the retracted position by the spring or the locking mechanism 23, not in contact with the spool 22. At this time, the spool 22 can rotate freely to retract and extend the webbing 9. When the triggering condition is met, such as sudden deceleration / collision / sudden pulling of the webbing 9, the sensing device of the locking mechanism 23 will release or drive the locking pawl, causing it to quickly pop out under the spring force. The popped-out locking pawl will lock... The webbing is fixed to a ratchet tooth at one end of the reel 22. Since the ratchet tooth and the reel 22 are rigidly integrated, after the locking pawl is engaged, the reel 22 can only rotate in the winding direction and cannot rotate in the pulling direction. This effectively restrains the occupants to the rear seat 1, preventing them from having a secondary collision with the vehicle interior. By setting a reel and locking mechanism inside the retractor, the reel allows the webbing to be smoothly wound and unwound and always fit the occupant's body, eliminating redundant slack and improving comfort and daily convenience. When the vehicle collides or decelerates violently, the locking mechanism is triggered by a sensor to instantly lock the reel, preventing the webbing from being pulled out further. This firmly restrains the occupants to the seat, effectively limiting their forward movement and avoiding secondary collisions with vehicle interior components. The two mechanisms work together to ensure the vehicle's convenience under normal conditions and its reliability in emergency situations.

[0067] In this utility model, a cavity is provided at the connection between the above-mentioned retractor mounting bracket 20 and the above-mentioned mounting plate 4; the above-mentioned retractor assembly 8 also includes a vibration damping element 24; the shape of the above-mentioned vibration damping element 24 matches the shape of the above-mentioned cavity; the above-mentioned vibration damping element 24 is detachably connected to the above-mentioned retractor mounting bracket 20 through the above-mentioned cavity.

[0068] In some embodiments, such as Figure 7 As shown, a cavity is provided at the connection between the retractor mounting bracket 20 and the mounting plate 4; the retractor assembly 8 also includes a vibration damping element 24, which, for example, can be a vibration damping pad made of rubber, to reduce the vibration noise generated by the retractor 21 during driving; the shape of the vibration damping element 24 matches the shape of the cavity, and the vibration damping element 24 is detachably connected to the retractor mounting bracket 20 through the cavity. The rubber vibration damping element effectively attenuates and isolates high-frequency vibrations from the vehicle body and road surface, eliminating abnormal noises caused by resonance in the retractor and improving the quietness and comfort inside the vehicle; at the same time, the design of the vibration damping element buffers the hard impacts and friction between components, protects the retractor and its mounting points, reduces the risk of wear and loosening caused by long-term micro-movements, and extends the service life of the retractor assembly.

[0069] In other embodiments, the vibration damping element 24 can be configured according to the actual situation.

Figure 2 As shown, at this time, the seat cushion 3, the first seat back 2, and the second seat back 25 are parallel. By setting up a rear seat with a seat cushion, a first seat back, and a second seat back, a flat sleeping space is created within the limited interior depth of the vehicle, expanding the vehicle's functionality and practicality; and its integrated flip-up structure ensures the flatness and support of the rear seats after they are converted into a bed, improving the comfort of passengers when resting.

[0072] The working principle of this vehicle is as follows:

[0073] In everyday situations, occupants can easily adjust the fore-and-aft position of the rear seat 1 via the sliding connection between the slide rail 18 and the slider 19, or flip the first seat back 2 and the second seat back 25 together to form a bed, meeting the occupants' needs for sitting and resting. Simultaneously, the roller 22 within the retractor 21 provides rewinding force, ensuring the webbing 9 always conforms to the body, and the buckle 14 is securely positioned in the fourth mounting slot. During driving, the vibration damping element 24 effectively absorbs vibrations, reducing the noise generated by the retractor 21.

[0074] When a collision occurs, the locking mechanism 23 inside the retractor 21 locks the reel 22, the webbing 9 is locked, and the load of the guide ring 10 is borne by the conical triangular tower structure composed of the rear floor assembly, the seat crossbeam assembly 16 and the mounting plate 4. The load of the buckle 14 is effectively distributed through the seat cushion 3, the slide rail 18, and finally by the front floor assembly 17 and the body frame, so as to firmly restrain the occupants in the safe area of ​​the rear seat 1 and reduce the risk of injury.

[0075] The beneficial effects of this utility model are:

[0076] The vehicle of this utility model includes a rear seat; the rear seat includes a first seat back and a seat cushion; the first seat back and the seat cushion are rotatably connected; a mounting plate; the mounting plate is disposed on the side of the first seat back away from the seat cushion; the mounting plate is provided with a first mounting groove and a second mounting groove; the first mounting groove is disposed at the bottom of the mounting plate; the second mounting groove is disposed away from the first mounting groove; the height of the second mounting groove is greater than the height of the first seat back; a seat belt assembly; the seat belt assembly includes a retractor assembly, a webbing, and a guide ring; the retractor assembly is detachably connected to the first mounting groove; the guide ring is detachably connected to the second mounting groove; one side of the webbing is fixedly connected to the retractor assembly; the other side of the webbing passes through the guide ring. The seat belts are positioned behind the rear seats, with the retractor and guide ring of the seat belt assembly located independently of the rear seats. This allows the rear seats to move forward and backward or fold down, increasing the flexibility of rear seat configuration and making the rear seat frame lighter. Furthermore, the guide ring is higher than the seat back, forming a three-point seat belt, improving the vehicle's space utilization. Integrating the two retractors and two guide rings into the mounting plate enhances the strength of the mounting structure. Combined with the rear floor assembly, seat crossbeam assembly, and mounting plate, a conical triangular tower structure is formed, further strengthening the installation structure of the dual seat belts.
