Description

Technical Field

[0001] This invention relates to the field of vehicle-related technologies, and in particular to a seat belt guide adjustment structure, a vehicle seat, a seat belt adjustment method for a vehicle seat, electronic equipment, a storage medium, and a computer program product. Background Technology

[0002] In existing technology, vehicle seats are equipped with seat belts. In current vehicles, such as 5-seater sedans, the rear seat retractor is usually located on the storage rack, with the lower end typically positioned on the floor. The webbing extends through an opening in the trim panel and is secured to the seat back. However, due to the limitations of vehicle layout, the webbing can only be fixed along a specific path when worn. This can lead to neck entrapment or shoulder slippage when worn by different individuals. As seat belt usage increases in the future, webbing discomfort is likely to become a major source of consumer complaints.

[0003] To address this, existing technology adds a seatbelt guide adjustment structure (Hook) to the seat back to guide the webbing. The seatbelt guide adjustment structure is an injection-molded part, usually fixed to the backrest with Phillips head screws, and prevents the webbing from slipping towards the occupant's neck when worn.

[0004] However, existing seatbelt webbing technology cannot accommodate occupants of all body types, resulting in two main issues: ① Comfort: Because the current seatbelt guiding and adjusting structure is fixed in position, taller occupants may experience webbing slipping off their shoulders, while smaller occupants may experience webbing around their necks; ② Safety: During a collision, webbing around the neck may increase the risk of neck injuries, while shoulder slippage may prevent the seatbelt from effectively restraining the occupant. Both of these issues reduce the effectiveness of the restraint system and seriously threaten occupant safety. Summary of the Invention

[0005] Therefore, it is necessary to address the technical problem that existing seat belt guide adjustment structures cannot adaptively adapt to occupants of various body types by providing a seat belt guide adjustment structure, a vehicle seat, a seat belt adjustment method for a vehicle seat, an electronic device, a storage medium, and a computer program product.

[0012] Further, calculating the optimal position of the moving module on the base based on the occupant mass includes: When the occupant mass is less than the maximum mass value but greater than the minimum mass value, the optimal position is calculated as follows: Where P is the optimal position, d is the displacement coefficient, and K is the mass coefficient. This represents the maximum mass value. When the occupant mass is greater than or equal to the maximum mass value, the optimal position is determined to be the minimum adjustable position; When the occupant mass is less than or equal to the minimum mass value, the optimal position is determined to be the maximum adjustable position.

[0015] The present invention provides a computer program product, including a computer program / instructions, which, when executed by a processor, implement the vehicle seat belt adjustment method as described above.

[0016] This invention drives a moving module to move on a base set on the back of the vehicle seat via a transmission mechanism, thereby driving the guide ring of the moving module to guide the seat belt webbing of the vehicle and actively and infinitely adjust the position of the occupant's shoulder seat belt.

[0025] like Figures 1 to 6 As shown, an embodiment of the present invention provides a seat belt guide adjustment structure 1, comprising: a base 11, a moving module 12, a transmission mechanism 13, and a guide ring 14, wherein: The base 11 is used to fix it to the back of the vehicle seat; The mobile module 12 is slidably mounted on the base 11; The transmission mechanism 13 is mounted on the base 11 and is used to drive the moving module 12 to slide along the extending direction of the base 11; The guide ring 14 is connected to the moving module 12 and is used to guide the seat belt webbing of the vehicle.

[0026] Specifically, such as Figure 7 and Figure 8As shown, a seat belt guide adjustment structure 1 is provided on the seat back 2 of the vehicle seat, and a base 11 is used to fix it to the seat back 2. The moving module 12 is slidably disposed on the base 11 and can slide along the extension direction of the base 11, thereby being able to move closer to or further away from the seat headrest 3.

[0027] like Figures 2 to 6 As shown, the transmission mechanism 13 is mounted on the base 11. In some embodiments, the seat belt guide adjustment structure 1 further includes a housing 15, which shields the transmission mechanism 13. The transmission mechanism 13 is connected to a moving module 12, which drives the moving module 12 to slide.

[0028] The guide ring 14 is a ring-shaped structure with a hole in the middle through which the seat belt webbing passes. The guide ring 14 is fixedly connected to the moving module 12. When the moving module 12 slides, it will cause the guide ring 14 to slide together, thereby guiding the seat belt webbing closer to or away from the seat headrest 3. When the seat belt webbing is close to the seat headrest 3, the seat belt retractor will pull the seat belt webbing closer to prevent the webbing from slipping. When the seat belt webbing is away from the seat headrest 3, the seat belt webbing will loosen to prevent strangulation.

[0029] This invention drives a moving module to move on a base set on the back of the vehicle seat via a transmission mechanism, thereby driving the guide ring of the moving module to guide the seat belt webbing of the vehicle and actively and infinitely adjust the position of the occupant's shoulder seat belt. This can accurately match the occupant's body shape and has a better seat belt wearing experience.

[0030] like Figures 1 to 6 As shown, another embodiment of the present invention provides a seat belt guide adjustment structure 1, comprising: a base 11, a moving module 12, a transmission mechanism 13, and a guide ring 14, wherein: The base 11 is used to fix it to the back of the vehicle seat; The mobile module 12 is slidably mounted on the base 11; The transmission mechanism 13 is mounted on the base 11 and is used to drive the moving module 12 to slide along the extending direction of the base 11; The guide ring 14 is connected to the moving module 12 and is used to guide the seat belt webbing of the vehicle. The moving module 12 includes a slider 121 and a fixed shaft 122 fixedly connected to the slider 121. A worm gear 123 is fixedly connected to the fixed shaft 122. The end of the fixed shaft 122 is fixedly connected to the guide ring 14. The transmission mechanism 13 drives the slider to slide along the base 11 by driving the worm gear 123 to rotate. The base 11 is provided with guide rails 111 on both sides, and the slider 121 is provided with a downward flange 1211, which is sleeved on the guide rails 111. The transmission mechanism 13 includes a motor 131, a worm gear 132, and a transmission gear set 133. The motor 131 is fixedly connected to the base 11 and connected to the transmission gear set 133. One end of the worm gear 132 is connected to the transmission gear set 133, and the other end extends along the extension direction of the base 11. The worm gear 132 meshes with the worm wheel 123.

[0031] Specifically, the seat belt guide adjustment structure 1 includes a base 11, a moving module 12, a transmission mechanism 13, and a guide ring 14.

[0032] like Figures 2 to 6 As shown, the base 11 serves as the main support for the entire device. The base 11 is fixedly connected to the seat back 2 of the vehicle seat by bolts or clips. To achieve smooth sliding of the moving module 12, guide rails 111 are symmetrically provided on both sides of the base 11. The cross-sectional shape of the guide rails 111 can be T-shaped, I-shaped, or a simple groove structure, used to restrict the degree of freedom of movement of the moving module 12, ensuring that it can only slide along the extension direction of the base 11.

[0033] The moving module 12 includes a slider 121 and a fixed shaft 122 fixedly connected to the slider 121. To enhance motion stability, the bottom or side of the slider 121 is provided with a downward flange 1211, which is sleeved on the aforementioned guide rail 111. This sleeved structure can effectively prevent shaking during movement. Meanwhile, the end of the fixed shaft 122 is fixedly connected to a guide ring 14. Preferably, the guide ring 14 includes a guide ring body 141 and a second fastening bolt 142, which bolts the guide ring body 141 to the end of the fixed shaft 122. The guide ring body 141 adopts a wear-resistant, high-strength annular structure, and its interior has holes for the seat belt webbing to pass through. When the transmission mechanism 13 drives the moving module, the guide ring 14 moves synchronously. A worm gear 123 cooperating with the transmission mechanism is also fixedly connected to the fixed shaft 122. The motor 131 drives the worm gear 132 to rotate in both directions, thereby causing the assembly formed by the worm wheel 123, base 11, and guide ring 14 to move in the forward / reverse direction. The worm wheel 123 and worm gear 132 can be made of plastic. Preferably, it includes two fixed shafts 122, and the worm wheel 123 can be connected to the fixed shafts 122 through a plastic coating process.

[0034] To further optimize the mechanical performance during the sliding process, in some embodiments, a slider pad 124 is also provided at the bottom of the slider 121. The slider pad 124 can be made of a material with a low coefficient of friction and self-lubricating properties. By setting the slider pad 124, the frictional resistance between the slider 121 and the guide rail 111 can be effectively reduced, the starting torque when the transmission mechanism 13 drives the slider 121 to slide can be reduced, thereby reducing the load pressure on the motor 131; at the same time, the pad also has a certain buffering effect, which can absorb the small vibrations during the sliding process, improve the smoothness of the device operation and reduce the motion noise.

[0035] In some embodiments, the seat belt guide adjustment structure 1 further includes a housing 15, on which a groove 151 is provided, a fixed shaft 122 passes through the groove 151 and is fixedly connected to a guide ring 14 located on the housing 15.

[0036] The transmission mechanism 13 is mounted on the base 11 and specifically includes a motor 131, a worm gear 132, and a transmission gear set 133. The motor 131, serving as the power source, is fixedly connected to the base 11 by bolts or welding. The motor 131 is preferably a servo motor. Specifically, a step is provided in the base 11, and the motor 131 is fixedly mounted on the step. The output shaft of the motor 131 meshes with the transmission gear set 133. One end of the worm gear 132 is connected to the transmission gear set 133, and the other end extends horizontally along the extension direction of the base 11.

[0037] In some embodiments, the transmission gear set 133 includes a first transmission gear 1331 and a second transmission gear 1332. The output shaft of the motor 131 is connected to the first transmission gear 1331 via a coupling 134. The first transmission gear 1331 meshes with the second transmission gear 1332, and the second transmission gear 1332 is connected to one end of the worm gear 132. Preferably, the first transmission gear 1331 and the second transmission gear 1332 are bevel gears.

[0038] A thread is provided on the worm 132, which meshes with the worm wheel 123 sleeved on the fixed shaft 122. When the motor 131 drives the transmission gear set 133 to rotate, it drives the worm 132 to rotate, and then through the meshing action of the worm wheel and worm, it finally drives the worm wheel 123 located on the slider 121 to rotate. This rotational motion is converted into a linear translation of the moving module 12 along the extension direction of the base 11 via the fixed shaft 122.

[0039] In some embodiments, the base 11 includes a frame 110, a bearing 112, and a first fastening bolt 113. Guide rails 111 are symmetrically arranged on both sides of the frame 110. A base through hole 1101 is formed at the first end of the frame 110. The bearing 112 is fixedly connected within the base through hole 1101, and the frame 110 is fixedly connected to the seat back 2 of the vehicle seat by the first fastening bolt 113. A motor 131 is fixedly mounted on a step 1102 at the second end of the frame 110. The frame 110 also has a worm gear receiving groove 1103 extending from the first end to the second end. The worm gear 132 is received in the worm gear receiving groove 1103, and its end is supported by the bearing 112.

[0040] This embodiment uses a transmission mechanism to drive a moving module to move on a base set on the seat back of the vehicle seat. This, in turn, moves the guide ring of the moving module, guiding the seat belt webbing and actively and steplessly adjusting the position of the occupant's shoulder seat belt. This allows for precise matching of the occupant's body shape, providing users with intelligent webbing adjustment functionality, enhancing interactivity, and eliminating the neck-strapping discomfort caused by the limited placement of traditional webbing. This reinforces the theme of a modern intelligent cockpit and offers superior seat belt wearability. Furthermore, this embodiment utilizes a worm gear mechanism to provide a wider adjustment range for occupants of different body types with high precision. This allows for stepless continuous adjustment based on extremely subtle changes in occupant weight, avoiding the abrupt changes of traditional step-like adjustments. This results in greater adaptability while also ensuring durability, meeting the vehicle's lifespan requirements.

[0041] like Figure 7 and Figure 8 As shown, an embodiment of the present invention provides a vehicle seat, including: a seat back 2, a seat headrest 3, a seat base 4, and a seat belt guide adjustment structure 1 as described above. The seat headrest 3, the seat back 2, and the seat base 4 are connected in sequence. The base 11 of the seat belt guide adjustment structure 1 is fixedly connected to the seat back 2. The vehicle's seat belt webbing passes through the guide ring 14 of the seat belt guide adjustment structure 1.

[0042] Specifically, the bottom of the seat backrest 2 is connected to the seat base 4, and the top of the seat backrest 2 is connected to the seat headrest 3. The vehicle seat belt is installed using existing technology. The seat belt guide adjustment structure 1, as described above, is installed on the top of the seat backrest 2. The seat belt webbing passes through the guide ring 14 and is adjusted by the guide ring 14.

[0043] This invention drives a moving module to move on a base set on the back of the vehicle seat via a transmission mechanism, thereby driving the guide ring of the moving module to guide the seat belt webbing of the vehicle and actively and infinitely adjust the position of the occupant's shoulder seat belt. This can accurately match the occupant's body shape and has a better seat belt wearing experience.

[0044] like Figure 9The diagram shown is a flowchart of a vehicle seat seat belt adjustment method according to an embodiment of the present invention, as described above, including: Step S901: Obtain the occupant mass of the occupant seated in the vehicle. Step S902: Obtain the current position of the moving module 12 of the seat belt guide adjustment structure 1 on the base 11; Step S903: Calculate the optimal position of the moving module 12 on the base 11 based on the occupant mass; Step S904: Calculate the target displacement based on the optimal position and the current position; Step S905: Control the moving module 12 to move the target displacement on the base 11.

[0045] Specifically, this invention can be applied to electronic devices with processing capabilities, such as vehicle controllers. For example, the Electronic Control Unit (ECU) of a vehicle.

[0046] Specifically, step S901 is first executed to obtain the occupant mass of the occupant sitting in the vehicle seat.

[0047] Specifically, after the vehicle is ignited, the controller first acquires the occupant's mass as they sit in the vehicle seat. The occupant mass (M) can be obtained through a sensor integrated into the seat, or the user can input their weight and convert it into occupant mass. The sensor is a pressure sensor installed at the bottom of the seat. Preferably, the pressure sensor is a strain gauge sensor.

[0048] Simultaneously, step S902 is executed to obtain the current position of the moving module 12 of the seat belt guide adjustment structure 1 on the base 11.

[0049] Specifically, the controller acquires the current position of the mobile module 12 on the base 11 in real time. The current position of the mobile module 12 on the base 11 refers to the distance of the mobile module 12 relative to the origin of the base 11.

[0050] Then, step S903 is executed to calculate the optimal position of the moving module 12 on the base 11 based on the occupant mass. Specifically, the optimal position is determined based on the occupant mass. The optimal position can be determined through multiple experiments for different occupant masses, and the optimal position for other occupant masses can be calculated.

[0051] Then, step S904 is executed to calculate the target displacement based on the optimal position and the current position.

[0052] Specifically, the target displacement is the difference between the optimal position and the current position. Therefore, subtracting the optimal position from the current position gives the target displacement.

[0053] Finally, step S905 is executed, controlling the moving module 12 to move the target displacement on the base 11.

[0054] Specifically, the controller that performs the seat belt adjustment method for a vehicle seat in this embodiment is communicatively connected to the transmission mechanism 13, and controls the transmission mechanism 13 to drive the moving module 12 to move the target displacement.

[0055] The current position of the mobile module 12 on the base 11 can be obtained by a position sensor or by video recognition.

[0056] To simplify calculations, since there is a target displacement each time the moving module 12 is controlled, the current position of the moving module 12 on the base 11 is actually the position of the moving module 12 after the last target displacement. Therefore, the position of the moving module 12 is initialized as the origin position, and then the target displacement is continuously recorded each time. Based on each target displacement, the position of the moving module 12 after the target displacement is calculated as the previous position plus the target displacement. Here, the target displacement is a directional displacement, and the origin is pre-specified. In some embodiments, the end of the base 11 furthest from the headrest 3 is taken as the origin, and the direction of movement towards the headrest 3 is taken as the positive direction. Figure 8 (The x-arrow in the image indicates the direction of the arrow; the direction away from the headrest is the negative direction.)

[0057] This invention assesses occupant weight and automatically adjusts the position of the seatbelt guide adjustment structure's moving module to place the occupant in the optimal seatbelt wearing position, improving wearing comfort. This invention can precisely match occupant body shape, providing superior seatbelt wearing performance. It can be applied to all subsequent vehicles equipped with this seatbelt guide adjustment structure, enhancing overall vehicle safety.

[0058] In one embodiment, calculating the optimal position of the moving module 12 on the base 11 based on the occupant mass includes: When the occupant mass is less than the maximum mass value but greater than the minimum mass value, the optimal position is calculated as follows: Where P is the optimal position, d is the displacement coefficient, and K is the mass coefficient. This represents the maximum mass value. When the occupant mass is greater than or equal to the maximum mass value, the optimal position is determined to be the minimum adjustable position; When the occupant mass is less than or equal to the minimum mass value, the optimal position is determined to be the maximum adjustable position.

[0059] Specifically, through multiple experimental measurements or by consulting standards, the comfort calibration range of seat belts can be compared with the weight of dummies of different body types, as shown in Table 1.

[0060] Table 1. Comparison of Seat Belt Comfort Verification Range Values ​​and Weights of Dummy Figures of Different Sizes

[0061] The most comfortable position is when an occupant of the corresponding weight is seated with the distance from the occupant's neck to the edge of the seatbelt webbing in the width direction of the seat back ( ). Figure 8 The most comfortable distance in the x-direction (of the x-axis).

[0062] By acquiring multiple sets of mass and optimal location data, the mass coefficient used to characterize the relationship between mass and optimal location can be calculated as follows: ,in For the maximum mass value, For the minimum mass value, The maximum value for the most comfortable position. The minimum value is the most comfortable position.

[0063] On the other hand, the distance the seatbelt webbing moves in the width direction of the seat back is not exactly the same as the distance the moving module 12 moves on the base 11; there is a certain proportional relationship between the two. Through multiple experiments, the distance the moving module 12 moves on the base 11 can be obtained, corresponding to the distance the seatbelt webbing moves in the width direction of the seat back. Therefore, the displacement coefficient d is defined as the proportional relationship between the distance the moving module 12 moves on the base 11 and the distance the seatbelt webbing moves in the width direction of the seat back. (Displacement coefficient defined) ,in The unit movement distance of the moving module 12 on the base 11, for example, 10mm. The distance the seat belt webbing moves in the width direction of the seat back when the moving module 12 moves a unit distance on the base 11 is equal to the distance the moving module 12 moves.

[0064] Then, after obtaining the occupant mass, select the corresponding calculation method based on the occupant mass: When the occupant mass is less than the maximum mass value but greater than the minimum mass value, the optimal position is calculated as follows: Where P is the optimal position, d is the displacement coefficient, and K is the mass coefficient. This represents the maximum mass value. When the occupant mass is greater than or equal to the maximum mass value, the optimal position is determined to be the minimum adjustable position; When the occupant mass is less than or equal to the minimum mass value, the optimal position is determined to be the maximum adjustable position.

[0065] The minimum adjustable position is the smallest position relative to the origin on the base 11, typically 0, meaning it's adjusted to the origin of the base 11. Since the origin is the end of the base 11 furthest from the headrest 3, the minimum adjustable position is equivalent to this end, meaning the moving module 12 is adjusted to the end of the base 11 furthest from the headrest 3, maximizing the distance between the seatbelt webbing and the headrest 3. Because the occupant's head rests on the headrest 3, the occupant receives maximum seatbelt space, meeting the needs of heavier occupants.

[0066] The maximum adjustable position is the position furthest from the origin on the base 11, which is the maximum travel Smax of the moving module 12. Since the origin is taken as the end of the base 11 furthest from the headrest 3, the maximum adjustable position is equivalent to the end of the base 11 closest to the headrest 3. That is, the moving module 12 is adjusted to the end of the base 11 closest to the headrest 3, minimizing the distance between the seat belt webbing and the headrest 3. Since the occupant's head is placed on the headrest 3, the occupant will have minimal seat belt space, meeting the needs of smaller occupants.

[0067] After calculating the optimal position, calculate the target displacement S = P - S1, where S is the target displacement, P is the optimal position, and S1 is the current position.

[0068] For example, when the vehicle initially starts, the moving module 12 is at the origin, so its current displacement is 0. The first passenger sits down. Based on the passenger's weight, converted to mass, the optimal position is calculated to be 30mm. Therefore, the target displacement is S = 30 - 0 = 30mm. The moving module 12 is adjusted to move 30mm in the positive direction. The new position of the moving module 12 is recorded as 30mm. Now, the second passenger sits down. At this time, the current position of the moving module 12 is 30mm. Since the second passenger's mass is greater than the maximum mass value, the optimal position is 0. Therefore, the target displacement is calculated as S = 0 - 30 = -30mm. Thus, the moving module 12 is controlled to move 30mm in the negative direction, returning to the origin.

[0069] like Figure 10 The diagram shown is a flowchart of a preferred embodiment of the present invention, namely, a method for adjusting a vehicle seat belt as described above, comprising: Step S1001: Obtain the occupant mass M; Step S1002: Obtain the previous position S1 of the slider; Step S1003, if Then calculate If S is moved, then move S; otherwise, proceed to step S1004. Step S1004, if If S = -S1, then S = -S1; otherwise, proceed to step S1005. Step S1005, if Then S = Smax - S1, where Smax is the maximum travel distance of the moving module 12. If recognition fails, proceed to step S1006. Step S1006: Restore factory settings, set S=-S1, and move the slider back to the origin.

[0070] Specifically, after the vehicle is ignited, the electric high-intensity adjustment function is activated. The vehicle controller acquires the occupant mass M and the position of the guide device, and then... Figure 10 The logic of the electric guide adjustment device outputs the adjustment distance of the moving module 12 corresponding to the optimal wearing position based on the occupant's weight. The specific control logic is as follows: ① When the passenger's weight corresponds to the mass hour, ; ②When the passenger's weight corresponds to the mass At that time, S = -S1; ③ When the passenger's weight corresponds to the mass When S = Smax - S1.

[0071] At the same time, a factory reset function is set up so that when the vehicle controller fails to obtain the occupant weight or loses the previous state, it can automatically return to the factory position and recalculate and output the occupant weight.
