Description

Technical Field

[0001] This application relates to the field of vehicle safety technology, and in particular to a seat assembly, a seat belt reminder system, and a vehicle. Background Technology

[0002] Currently, in the rear seat layout of automobiles, two independent buckles must be installed to accommodate the seatbelt latches of passengers in adjacent seats. This design occupies extra space laterally, making the middle passenger's seat space cramped and affecting ride comfort and space utilization. To ensure the two buckles can be installed smoothly, the seat cushion must be designed with a large clearance notch. This notch not only disrupts the overall appearance of the seat cushion, making it look less refined and harmonious, but also, because the two buckles are closely arranged on the side of the seat cushion, it does not fully consider ergonomics and the actual riding experience of passengers, thus reducing the overall riding experience.

[0003] There is currently no effective solution to the above problems. Utility Model Content

[0004] The application provides a seat assembly, a seat belt reminder system, and a vehicle, aiming to improve the problems of the existing rear dual buckle lock design affecting passenger comfort, space utilization, and increasing costs.

[0006] The seat assembly of this application achieves the following beneficial effects: by using a shared buckle, the need for an independent buckle for each seat is reduced, material and manufacturing costs are lowered, and valuable lateral cabin space is saved. Especially in compact vehicles or vehicles with limited space, it allows passengers in the middle seat to have more legroom and hip space, improving riding comfort. The latch in the latch assembly can be selected to work alone or simultaneously with the shared buckle, so that the buckle can be used efficiently even when there is only one passenger, without worrying about wasting resources. When there are multiple passengers, they can choose the most suitable latch to use, enhancing the user adaptability of the seat belt system and solving the problems of the rear dual-buckle design affecting riding comfort, space utilization, and increasing costs.

[0007] Furthermore, the number of locking tongues is configured in a one-to-one correspondence with the number of seat belts.

[0008] Furthermore, the latch assembly includes: a first latch and a second latch, wherein the first latch and / or the second latch are optionally configured to cooperate with a shared latch; wherein the first latch and the second latch are detachably connected so that the first latch has a mating position embedded in the second latch, and when the first latch and the second latch are simultaneously mated with the shared latch, the first latch and the second latch are located in the mating position.

[0009] Furthermore, the plurality of seats includes an adjacent first seat and a second seat, a shared latch is disposed between the first seat and the second seat, and the shared latch is movably connected to at least one of the first seat and the second seat.

[0010] Furthermore, the seat belt assembly includes adjacent first and second seat belts, one of which is movably connected to the first seat, and the other of which is movably connected to the second seat; wherein, one of the first and second seat belts passes through a first latch, and the other of which passes through a second latch, and at least one of the first and second latches is optionally configured to cooperate with a shared buckle to achieve the fastening of the first and / or second seat belts.

[0012] Furthermore, the second latch includes: a second latch connecting handle, the second latch connecting handle being provided with a second through hole for the other of the first and second safety belts to pass through; a second latch body, one end of the second latch body being connected to the second latch connecting handle, the second latch body being provided with a second latch hole for engaging with a shared buckle; and a second fitting structure, the second fitting structure being disposed on the second latch body, the second fitting structure being detachably connected to the first fitting structure.

[0013] Furthermore, at least one of the first latch and the second latch is provided with a magnetic attractor that allows the first latch and the second latch to attract each other.

[0014] Furthermore, the shared latch includes: a latch frame and a latch structure. The latch frame extends along a first preset direction and has a locking space. The latch structure is disposed within the locking space and is used to engage with the seat assembly. The first latch and / or the second latch are movably disposed relative to the latch frame along the first preset direction.

[0015] Another aspect of this application provides a seatbelt reminder system, comprising: a seatbelt assembly; a latch assembly, wherein a first latch in the latch assembly generates first latch magnetic field data, and a second latch in the latch assembly generates second latch magnetic field data; a Hall sensor disposed within a shared buckle, the Hall sensor periodically detecting magnetic field data within the shared buckle; a pressure sensor periodically detecting pressure data on the vehicle seat; a display device displaying a target reminder status; and a controller electrically connected to both the pressure sensor and the Hall sensor, the controller controlling the display device to be in a target reminder mode based on the magnetic field data detected by the Hall sensor and the pressure data detected by the pressure sensor, the target reminder mode including at least: a safety mode, a first seatbelt unfastened reminder mode, a second seatbelt unfastened reminder mode, and a dual seatbelt unfastened reminder mode.

[0016] The seatbelt reminder system of this application achieves the following beneficial effects: Different magnetic field data generated by the first and second locking tongues are periodically detected by a Hall sensor. Combined with pressure data detected by a pressure sensor on the car seat, the controller can intelligently analyze the passenger's seating status and seatbelt usage. Based on this information, the system can automatically determine and switch the display device to the appropriate safety reminder mode. Through the dual monitoring of the Hall sensor and the pressure sensor, the system can more accurately identify whether the passenger is wearing the seatbelt correctly and whether there is an occupant in the seat. This design avoids false alarms or missed alarms due to incomplete information, ensuring the timeliness and accuracy of the reminders.

[0017] According to another aspect of the embodiments of this application, a vehicle is also provided, including a seat belt reminder system, wherein the seat belt reminder system is the one described above.

[0043] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0044] In rear-seat layouts, two independent buckles must be installed to accommodate the seatbelt latches of passengers in adjacent seats. This design occupies approximately 35mm of extra space laterally (Y-axis), making the middle rear passenger's seat cramped and impacting comfort and space utilization. To ensure proper installation of the two buckles, the seat cushion must have a large clearance notch. This notch not only detracts from the overall look of the cushion, making it less refined and harmonious, but may also reduce passenger satisfaction with the vehicle's interior quality. In today's market where consumers increasingly prioritize in-car comfort and visual aesthetics, this design flaw is undoubtedly a drawback.

[0045] Traditional double-lock designs often feature relatively large latches that can press against the buttocks of passengers, especially those who are slimmer, causing discomfort. Furthermore, the close arrangement of the two latches along the side of the seat cushion fails to adequately consider ergonomics and passenger comfort, thus diminishing the overall riding experience. In addition, the two latches increase material costs and involve extra manufacturing, assembly, and quality control processes, leading to higher overall production costs.

[0046] In conclusion, the traditional rear dual-latch lock design has significant shortcomings in terms of space utilization, user experience, appearance design, and cost-effectiveness. Innovative solutions are urgently needed to overcome these deficiencies and improve the overall riding experience.

[0047] This application provides a seat assembly, such as... Figure 1 and Figure 2 As shown, it includes: a plurality of seats; a buckle assembly connected to at least one seat, the buckle assembly including at least one shared buckle 30; a seat belt assembly connected to at least one seat, the seat belt assembly including a plurality of seat belts; a latch assembly connected to at least one seat belt, the latch assembly including a plurality of latches, wherein at least two of the plurality of latches are optionally configured to individually or simultaneously engage with the shared buckle 30 for locking.

[0048] The technical solution of this utility model reduces the need for an independent buckle for each seat by using a shared buckle 30, thereby reducing material and manufacturing costs and saving valuable lateral cabin space. Especially in compact vehicles or vehicles with limited space, it allows passengers in the middle seats to have more legroom and hip space, improving riding comfort. The latch in the latch assembly can be selected to work alone or simultaneously with the shared buckle, so that even when there is only one passenger, the buckle can still be used efficiently without worrying about wasting resources. When there are multiple passengers, they can choose the most suitable latch to use, enhancing the user adaptability of the seat belt system and solving the problems of the rear double buckle design affecting riding comfort, space utilization, and increasing costs.

[0049] Furthermore, multiple locking tongues are configured to correspond one-to-one with the number of seat belts.

[0050] The above-described optional embodiments achieve the following beneficial effects: each passenger has a corresponding seatbelt and locking tongue, ensuring that passengers can independently use the seatbelt according to their own needs and comfort. This not only improves safety but also increases passenger comfort and satisfaction. The corresponding design allows the system to accurately monitor the usage status of each seatbelt. This means that when a passenger is not properly fastened, the vehicle's seatbelt reminder system can quickly identify which seatbelt is not fastened and issue a corresponding warning, improving the targeting and effectiveness of seatbelt reminders.

[0051] In this embodiment, the latch assembly includes: a first latch 10 and a second latch 20. Please refer to [reference needed]. Figure 3 and Figure 4 The first latch 10 and / or the second latch 20 are optionally configured to cooperate with the shared latch 30; wherein the first latch 10 and the second latch 20 are detachably connected so that the first latch 10 has a mating position embedded in the second latch 20, and when the first latch 10 and the second latch 20 are simultaneously mated with the shared latch 30, the first latch 10 and the second latch 20 are in the mating position.

[0052] The technical solution of this utility model, by designing the first locking tongue 10 and the second locking tongue 20 to be used in conjunction with the same shared latch 30, allows for the use of two passengers with just one shared latch 30, whether used individually or in combination. This significantly reduces the space occupied by traditional double latch locks, thereby increasing the effective seating space in the rear, improving space utilization, reducing the impact of the latch protrusion on the occupants' buttocks, eliminating the additional material and processing costs caused by the double latch layout, and solving the problems of the existing rear double latch lock design affecting passenger comfort, space utilization, and increasing costs.

[0053] In one exemplary embodiment, the plurality of seats include adjacent first seats 80 and second seats 70, a shared latch 30 is disposed between the first seats 80 and the second seats 70, and the shared latch 30 is movably connected to at least one of the first seats 80 and the second seats 70.

[0054] The above-described optional embodiments achieve the following beneficial effects: placing the shared latch 30 between two adjacent seats reduces the need for each seat to have an independent latch, thereby saving lateral space on the sides of the seats. This is particularly important for compact vehicles, especially in rear seat layouts, as it helps create a more spacious and comfortable seating environment. The movable connection design between the shared latch and the seat makes it easier for passengers to access and use the shared latch, especially in confined vehicle environments, making latch use quicker and easier.

[0055] In this embodiment, the seat belt assembly includes adjacent first seat belts 50 and second seat belts 60. One of the first seat belts 50 and 60 is movably connected to a first seat 80, and the other is connected to a second seat 70. One of the first seat belts 50 and 60 passes through a first latch 10, and the other passes through a second latch 20. At least one of the first latch 10 and the second latch 20 is optionally configured to cooperate with a shared buckle 30 to achieve the fastening of the first seat belt 50 and / or the second seat belt 60. Specifically, the first seat belt 50 is movably connected to the first seat 80, and the second seat belt 60 is movably connected to the second seat 70.

[0056] The above-described optional embodiments achieve the following beneficial effects: by connecting two seat belts to adjacent seats and using a shared buckle, the lateral space occupied by each seat with an independent buckle can be effectively reduced, providing passengers with a more spacious seating environment, especially in the rear seat layout, where the legroom and hip space for the middle passenger is significantly improved. The first seat belt 50 is movably connected to the first seat 80, and the second seat belt 60 is movably connected to the second seat 70, meaning that passengers can adjust the position of the seat belts as needed to accommodate passengers of different body types. This design makes the use of seat belts more flexible and improves passenger comfort. The first seat belt 50 and the second seat belt 60 are respectively threaded through the first latch 10 and the second latch 20. The use of the latch assembly in conjunction with the shared buckle 30 simplifies the process of fastening the seat belt. Regardless of which seat belt is used, passengers can easily complete the fastening operation in a similar position without having to search for multiple buckles between seats.

[0057] In this embodiment, as Figure 5 As shown, the first latch 10 includes: a first latch connecting handle 11, a first latch body 12, and a first engaging structure 13. The first latch connecting handle 11 is provided with a first through hole for the first seat belt to pass through. One end of the first latch body 12 is connected to the first latch connecting handle 11. The first latch body 12 is provided with a first latch hole 124 for cooperating with the shared buckle 30 to fasten the first seat belt. The first engaging structure 13 is provided on the first latch body 12 and is used to detachably connect with the second latch 20.

[0058] The above-described optional embodiments achieve the following beneficial effects: The design of the first interlocking structure 13 allows the first locking tongue 10 and the second locking tongue 20 to be spliced ​​together when needed. When there is only one passenger in the rear row, the passenger can choose to use only one side of the locking tongue, thereby avoiding the problem of the traditional double locking tongue structure occupying too much lateral space. In the spliced ​​state, the two locking tongues can be inserted as a whole into a shared latch 30, reducing the size of the clearance required on the seat cushion, making the seat cushion look cleaner, and also avoiding the latch pressing on the passenger's buttocks when riding, thus enhancing the comfort of the ride.

[0059] In one exemplary embodiment, such as Figure 6 As shown, the second latch 20 includes: a second latch connecting handle 21, the second latch connecting handle 21 having a second through hole for the second seat belt to pass through; a second latch body 22, one end of the second latch body 22 being connected to the second latch connecting handle 21, the second latch body 22 having a second latch hole 224 for engaging with the shared buckle 30 to fasten the second seat belt; and a second fitting structure 23, the second fitting structure 23 being disposed on the second latch body 22, the second fitting structure 23 being detachably connected to the first fitting structure 13.

[0060] The above-described optional embodiments achieve the following beneficial effects: The detachable connection design between the second fitting structure 23 and the first fitting structure 13 allows the two latches to be quickly joined together as needed, forming a single unit that can be inserted into the same shared latch 30. In this combined usage mode, the seat cushion only needs to reserve space for one latch, greatly optimizing the interior space layout. Especially for vehicles with a three-seat rear layout, the independent working mode and combined usage mode of the two latches allow passengers to flexibly choose the latch usage method according to the actual number of passengers, ensuring optimal seating experience whether one person is seated or two people are seated side-by-side. Simultaneously, the detachable connection of the latches facilitates passenger operation when entering or leaving the vehicle, improving ease of use.

[0061] Furthermore, such as Figure 7 and Figure 8As shown, the first fitting structure 13 includes: a first protrusion 131, there are multiple first protrusions 131, the multiple first protrusions 131 are disposed on one side of the first latch body 12, and a first clearance groove 132 is disposed between two adjacent first protrusions 131; the second fitting structure 23 includes: a second protrusion 231, there are multiple second protrusions 231, the multiple second protrusions 231 are disposed on one side of the second latch body 22, and a second clearance groove 232 is disposed between two adjacent second protrusions 231; wherein, when the first latch 10 is in the engagement position of fitting with the second latch 20, the first protrusion 131 fits into the second clearance groove 232, and the second protrusion 231 fits into the first clearance groove 132.

[0062] The above-described optional embodiments achieve the following beneficial effects: the design of multiple first protrusions 131 and second protrusions 231 ensures the alignment accuracy of the first latch 10 and the second latch 20 during assembly. The first clearance groove 132 and the second clearance groove 232 between adjacent protrusions serve as guides and positions, enabling the latches to form a more stable whole after assembly, preventing loosening or misalignment during use, and improving passenger safety and overall stability. The cooperation between the first protrusion 131 and the second clearance groove 232, and between the second protrusion 231 and the first clearance groove 132, simplifies the assembly and disassembly process of the latches. This user-friendly operation is crucial for improving the user experience, especially in emergencies where the ability to unlock quickly is vital to passenger safety.

[0063] In one exemplary embodiment, the thickness of the first latch body 12 and the second latch body 22 can be set to 50% of the thickness of a conventional double-bolt latch body, and the thickness of the first protrusion 131 and the second protrusion 231 can also be set to 50% of the thickness of a conventional double-bolt latch body. That is, the sum of the thicknesses of the first latch body 12 and the first protrusion 131 is the same as the thickness of a conventional double-bolt latch body, and the sum of the thicknesses of the second latch body 22 and the second protrusion 231 is also the same as the thickness of a conventional double-bolt latch body. Thus, whether the two latches are used individually or in combination, they can cooperate with a conventional buckle to fasten the seatbelt, without requiring modification to the buckle, maximizing the commonality of components. Furthermore, in this embodiment, the thickness ratio of the first latch body 12 to the first protrusion 131 is 1:1, and the thickness ratio of the second latch body 22 to the second protrusion 231 is also 1:1. Of course, the thickness ratio of the first latch body 12 to the first protrusion 131, and the thickness ratio of the second latch body 22 to the second protrusion 231 can be adjusted according to the actual situation, for example, it can be 3:7, 4:6, 6:4, 7:3, etc. This embodiment does not limit this.

[0064] In one exemplary embodiment, there are two of each of the first protrusion 131, the first clearance groove 132, the second protrusion 231, and the second clearance groove 232. This symmetrical design not only improves design effectiveness from an engineering perspective but also, from an aesthetic standpoint, aligns better with modern industrial design trends, enhancing the vehicle's appearance. Furthermore, the design of two protrusions and clearance grooves simplifies mold manufacturing and assembly processes, reduces manufacturing difficulty, improves production efficiency, and facilitates mass production.

[0065] In this embodiment, the first latch body 12 includes: a first latch connecting section 121, a second latch connecting section 122, and a third latch connecting section 123. The first end of the first latch connecting section 121 is connected to the first latch connecting handle 11; the first end of the second latch connecting section 122 is connected to the second end of the first latch connecting section 121, and an angle is provided between the second latch connecting section 122 and the first latch connecting section 121; the first end of the third latch connecting section 123 is connected to the second end of the second latch connecting section 122, and an angle is provided between the third latch connecting section 123 and the second latch connecting section 122; and the first fitting structure 13 is disposed on the third latch connecting section 123.

[0066] The above-mentioned optional embodiments can achieve the following beneficial effects: the included angles formed between the first locking tongue connecting section 121 and the second locking tongue connecting section 122, and the included angles formed between the second locking tongue connecting section 122 and the third locking tongue connecting section 123, fully match the thickness of the seat belt and the thickness of the two locking tongue connecting handles, ensuring that the gap between the seat belts is sufficient when the locking tongues are closed, avoiding mutual squeezing or twisting of the seat belts when the locking tongues are inserted into the buckle. This not only affects the passenger's comfort but may also reduce the smoothness of the locking tongues inserting into the buckle, or even cause the seat belts to fail. In addition, the setting of the included angles also takes into account the guiding requirements when the locking tongues are inserted into the buckle, ensuring that the locking tongues can be inserted into the buckle smoothly and quickly, reducing resistance and misoperation during the insertion process. The three-section connecting structure of the first locking tongue body 12 and its included angle design solve the problem of seat belt squeezing caused by the double locking tongue arrangement, while ensuring the smooth insertion of the locking tongues, improving the convenience and safety of passengers using seat belts.

[0067] In an exemplary embodiment, the angle between the first latch connecting segment 121 and the second latch connecting segment 122 is A, and the angle between the second latch connecting segment 122 and the third latch connecting segment 123 is B, wherein 90°≤A≤180° and 90°≤B≤180°.

[0068] Furthermore, the second latch body 22 includes: a fourth latch connecting section 221, a fifth latch connecting section 222, and a sixth latch connecting section 223. The first end of the fourth latch connecting section 221 is connected to the second latch connecting handle 21; the first end of the fifth latch connecting section 222 is connected to the second end of the fourth latch connecting section 221, and an angle is provided between the fifth latch connecting section 222 and the fourth latch connecting section 221; the first end of the sixth latch connecting section 223 is connected to the second end of the fifth latch connecting section 222, and an angle is provided between the sixth latch connecting section 223 and the fifth latch connecting section 222; and the second fitting structure 23 is disposed on the sixth latch connecting section 223.

[0069] Furthermore, when the first latch 10 is in the engagement position where it engages with the second latch 20, at least a portion of the third latch connecting segment 123 abuts against at least a portion of the sixth latch connecting segment 223, the fourth latch connecting segment 221 and the first latch connecting segment 121 are symmetrically arranged about the contact surface of their abutment, and the fifth latch connecting segment 222 and the second latch connecting segment 122 are symmetrically arranged about the contact surface of their abutment.

[0070] The above-described optional embodiments achieve the following beneficial effects: When the first latch 10 and the second latch 20 are in the engaged position, the abutting design of the third latch connecting section 123 and the sixth latch connecting section 223 ensures the precise alignment of the latches during splicing, while providing contact points to enhance the overall stability after splicing. This symmetrical structural design allows the first latch 10 and the second latch 20 to form a more balanced and rigid whole when spliced, thereby enhancing the reliability and safety of the seat belt system. Through the symmetrical arrangement of the fourth latch connecting section 221 and the first latch connecting section 121 about the abutting contact surface, and the symmetrical design of the fifth latch connecting section 222 and the second latch connecting section 122, it is ensured that the latches can be inserted into the shared buckle 30 at an optimized angle in the spliced ​​state. This not only facilitates passenger operation but also reduces wear between the latches and the buckle, extending the service life of the components.

[0071] In an exemplary embodiment, the angle between the fourth latch connecting segment 221 and the fifth latch connecting segment 222 is also A, and the angle between the fifth latch connecting segment 222 and the sixth latch connecting segment 223 is also B, where 90°≤A≤180° and 90°≤B≤180°.

[0072] In one exemplary embodiment, at least one of the first latch 10 and the second latch 20 is provided with a magnetic attractor that allows the first latch 10 and the second latch 20 to attract each other. This magnetic attraction allows the first latch 10 and the second latch 20 to automatically align and fit together when engaged, eliminating the need for precise manual alignment by the passenger, simplifying the assembly process and improving ease of use. The magnetic attractor can be a magnetic portion of the first latch 10 and / or the second latch 20. For example, a portion of the first latch body 12 and / or a portion of the second latch body 22 can be made magnetic, or a portion of the first fitting structure 13 and / or a portion of the second fitting structure 23 can be made magnetic. Alternatively, a magnetic sheet or strip can be attached to the first latch 10 and / or the second latch 20, as long as it allows for convenient engagement of the first latch 10 and the second latch 20. This embodiment does not limit the specific form of the magnetic attractor.

[0073] In one exemplary embodiment, both the first protrusion 131 and the second protrusion 231 are magnetic, and the magnetic field strengths of the first protrusion 131 and the second protrusion 231 are set differently. By respectively attaching the two magnetic components to the first protrusion 131 and the second protrusion 231, the engagement operation of the locking tongue becomes more convenient, further improving ease of use. Moreover, the different magnetic field strengths of the first protrusion 131 and the second protrusion 231, in conjunction with the Hall sensor described later, can accurately provide seatbelt unfastened reminders.

[0074] In this embodiment, please refer to Figure 9 As shown, the shared latch 30 includes a latch frame 39 and a latching structure. The latch frame 39 extends along a first preset direction and has a locking space. The latching structure is disposed within the locking space and is used to engage with the seat assembly. The first latch 10 and / or the second latch 20 are movably disposed relative to the latch frame 39 along the first preset direction. The first preset direction is the length direction from the first end to the second end of the latch frame 39.

[0075] The latch in this embodiment can achieve the following beneficial effects: the first preset direction of the latch frame 39 is designed to provide a clear guide for the latch structure in the locking space, ensuring that the latch can smoothly enter the locking space along the expected path when it is inserted. At the same time, the latch structure realizes stable locking after the latch is inserted, preventing the latch from accidentally disengaging during vehicle operation and ensuring passenger safety.

[0076] Please refer to Figure 10 and Figure 11As shown, the latch lock frame 39 includes: a middle connecting plate 391 and two side plates 395, one side plate 395 is connected to the first end of the middle connecting plate 391, and the other side plate 395 is connected to the second end of the middle connecting plate 391. The two side plates 395 and the middle connecting plate 391 form a locking space. At least one limiting protrusion 394 is provided on the inner side of each of the two side plates 395. The limiting protrusion 394 is used to limit at least one of the first latch body 12 and the second latch body 22.

[0077] The above optional embodiments can achieve the following beneficial effects: the locking space formed by the two side plates 395 and the middle connecting plate 391 provides precise insertion guidance and positioning for the first locking tongue body 12 and the second locking tongue body 22, while the limiting protrusion 394 set on the inner side of the side plate further restricts the lateral and longitudinal movement of the locking tongue, ensuring the stability of the locking tongue in the locked state and reducing the risk of the locking tongue loosening during vehicle movement.

[0078] In an exemplary embodiment, two limiting protrusions 394 are provided on the inner sides of both side plates 395. The two limiting protrusions 394 correspond to two first protrusions 131 respectively. The cooperation between the limiting protrusions 394 and the first protrusions 131 can provide positioning and guiding functions during the insertion of the bolt into the latch, ensuring that the bolt will not deviate or shake during the insertion process, thereby improving the locking accuracy and stability.

[0079] In one exemplary embodiment, such as Figure 12 , Figure 13 and Figure 14 As shown, the shared latch 30 also includes: an upper latch cover 31, the aforementioned snap-fit ​​structure, and a lower latch cover 34. The snap-fit ​​structure includes: a locking pin 32, a snap-fit ​​button 33, a spring 35, a latch 36, a pop-out element 37, and an arc-shaped element 38. The locking pin 32 slides into the arc-shaped groove 393 of the snap-fit ​​frame 39, the arc-shaped element 38 slides into the sliding groove 392 of the snap-fit ​​frame 39, the latch 36 is hinged to the round holes on both sides of the snap-fit ​​frame 39, the pop-out element 37 is hinged to the arc-shaped element 38, the two ends of the spring 35 respectively engage with the pop-out element 37 and the latch 36, the locking pin 32 engages with the pop-out element 37 and the latch 36 respectively, and the hook-shaped structure of the latch 36 engages with the first latch hole 124 and the second latch hole 224. Since the specific installation positions of the above components are common knowledge to those skilled in the art, they will not be described in detail.

[0080] According to another specific embodiment of this application, a seatbelt reminder system is also provided, such as... Figure 15As shown, the system includes: a seatbelt assembly; a latch assembly, wherein a first latch in the latch assembly generates first latch magnetic field data, and a second latch in the latch assembly generates second latch magnetic field data; a Hall sensor 40, which is disposed within the shared buckle 30 and is used to periodically detect magnetic field data within the shared buckle 30; a pressure sensor, which is used to periodically detect pressure data on the car seat; a display device, which is used to display the target reminder status; and a controller, which is electrically connected to both the pressure sensor and the Hall sensor 40, and controls the display device to be in the target reminder mode based on the magnetic field data detected by the Hall sensor 40 and the pressure data detected by the pressure sensor. The target reminder modes include at least: a safety mode, a first seatbelt unfastened reminder mode, a second seatbelt unfastened reminder mode, and a dual seatbelt unfastened reminder mode.

[0081] The above-described embodiment of the seatbelt reminder system achieves the following beneficial effects: Different magnetic field data generated by the first latch 10 and the second latch 20 in the latch assembly are periodically detected by the Hall sensor 40. Combined with pressure data detected by the pressure sensor on the car seat, the controller can analyze the passenger's seating status and seatbelt usage. Based on this information, the system can automatically determine and switch the display device to the appropriate reminder mode. Through the dual monitoring of the Hall sensor 40 and the pressure sensor, the system can accurately identify whether there is an occupant in the seat and whether the passenger is wearing the seatbelt correctly. This design avoids false alarms or missed alarms caused by incomplete information from only the pressure sensor, ensuring the timeliness and accuracy of the reminders.

[0082] According to another embodiment of this application, a vehicle is also provided, including a seat belt reminder system, which is the seat belt reminder system described above.

[0083] The vehicle in this application embodiment can achieve the following beneficial effects: by integrating the above-mentioned seat belt reminder system, the vehicle not only has a significant improvement in safety, but also improves ride comfort, space utilization, cost control and maintenance convenience.
