[0042] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.
[0043] The seat belt latch device 10 of the present application will be described in detail below with reference to the drawings and in combination with embodiments. The seat belt latch device 10 is applied to a vehicle, and the seat belt latch device 10 is installed on one side of the seat 100. The seat belt latch device 10 is used for snap-fitting with the buckle in the seat belt. Thus, the layout position of the seat belt latch device 10 in the vehicle can determine the matching effect of the seat belt on the driver and passengers.
[0044] The seat belt latch device 10 according to the embodiment of the present application includes: a latch assembly 1, a mounting base 2, a first adjustment mechanism 3, and a second adjustment mechanism 4.
[0045] Among them, the mounting base 2 is connected to the seat 100, the latch assembly 1 is installed on the mounting base 2, and the position of the latch assembly 1 relative to the mounting base 2 is adjustable, so that the latch assembly 1 can be adjusted to a corresponding position according to the body size of the driver and passengers and the driving needs, so as to improve the comfort when wearing the seat belt while ensuring the protection effect of the seat belt on the driver and passengers.
[0046] Combined with Figure 9 andFigure 11 As shown, the first adjustment mechanism 3 is movably mounted on the mounting base 2. The first adjustment mechanism 3 is connected to the plug lock assembly 1. The first adjustment mechanism 3 can drive the plug lock assembly 1 to rotate about the first axis 101 and can drive the plug lock assembly 1 to move synchronously relative to the mounting base 2. Moreover, the position of the first adjustment mechanism 3 relative to the mounting base 2 in the first direction can be adjusted reciprocally. The second adjustment mechanism 4 is mounted on the mounting base 2, and the second adjustment mechanism 4 is connected to the first adjustment mechanism 3. And the second adjustment mechanism 4 is used to drive the first adjustment mechanism 3 to move reciprocally in the first direction, and the first direction is arranged perpendicular to the first axis 101.
[0047] Combined with Figure 5 and Figure 9 As shown, the mounting base 2 is the mounting carrier of the second adjustment mechanism 4. By driving the first adjustment mechanism 3 to move through the second adjustment mechanism 4, the position adjustment of the first adjustment mechanism 3 relative to the mounting base 2 in the first direction can be realized, and the first adjustment mechanism 3 can drive the plug lock assembly 1 to move synchronously, so as to realize the position adjustment of the plug lock assembly 1 relative to the mounting base 2 in the first direction.
[0048] Combined with Figure 5 and Figure 11 As shown, the first adjustment mechanism 3 is the mounting carrier of the plug lock assembly 1. Under the action of the first adjustment mechanism 3, the plug lock assembly 1 can be driven to rotate about the first axis 101, so as to adjust the inclination angle of the plug lock assembly 1, thereby adjusting the plugging and matching angle between the buckle and the plug lock assembly 1 and improving the user experience.
[0049] Thus, through the cooperation of the first adjustment mechanism 3 and the second adjustment structure, the adjustment of the plug lock assembly 1 in the first direction and the inclination angle can be realized, so as to adjust the plug lock assembly 1 to a position suitable for plugging and matching with the buckle, thereby improving the adaptability between the user and the seat belt.
[0050] Wherein, the first axis 101 is arranged perpendicular to the first direction. When the seat belt plug lock device 10 is applied to a vehicle, it is preferably arranged that the first direction is the X-direction of the vehicle, and the first axis 101 is perpendicular to the XZ plane. That is to say, the position of the plug lock assembly 1 relative to the mounting base 2 in the first direction is adjustable, and the orientation of the plug lock assembly 1 can also be adjusted accordingly based on the real-time working conditions of the vehicle.
[0051] It should be noted that currently, to provide better safety and convenience for the vehicle occupants, seat belts are essential devices in vehicles, and the application of seat belts protects the safety of vehicle occupants. In the related art, the position of the seat belt buckle lock in the vehicle is fixed, resulting in a fixed mating position between the buckle and the seat belt buckle lock, which cannot be adjusted according to the body size of the vehicle occupants, affecting the use experience of the occupants. At the same time, when the vehicle collides, the occupants will have a downward diving movement trend, and the seat belt with a fixed mating position cannot effectively prevent the occupants from diving, and the protection effect is limited.
[0052] In the present application, the second adjustment mechanism 4 can adjust the position of the buckle lock assembly 1 relative to the mounting seat 2 in the first direction, and the first adjustment mechanism 3 can adjust the orientation of the opening of the buckle lock assembly 1 (i.e., the slot structure for mating with the buckle), so that the position of the buckle lock assembly 1 relative to the seat 100 can be adaptively adjusted according to the body size of the occupants, so as to improve the matching effect between the seat belt and the occupants while ensuring the restraint and protection of the seat belt for the occupants.
[0053] It can be understood that when a frontal collision occurs to the vehicle, the occupants have a downward diving movement trend under the action of inertia, resulting in a deteriorated protection effect of the seat belt on the occupants.
[0054] Combined with Figure 8 and Figure 10 as shown, Figure 10 the buckle lock assembly 1 shown in Figure 8 is set to tilt forward to improve the comfort of the occupants wearing the seat belt; Figure 10 the buckle lock assembly 1 shown in Figure 8 is set to tilt backward to improve the restraint effect of the seat belt on the occupants and effectively prevent the occupants from diving. Among them, when a frontal collision occurs to the vehicle, the buckle lock assembly 1 can quickly switch from the posture shown in
[0055] That is to say, the buckle lock assembly 1 in the present application can effectively prevent the occupants from diving by changing its position, and improve the protection effect of the seat belt on the occupants.
[0056] Combined with Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments of the present application, the mounting seat 2 has a receiving space 201, the second adjustment mechanism 4 is arranged in the receiving space 201, and the position of the latch assembly 1 relative to the mounting seat 2 is adjusted by the first adjustment mechanism 3, so that the latch assembly 1 can be selectively accommodated in the receiving space 201, thereby hiding the latch assembly 1 in the mounting seat 2. That is, when the user does not need to use the safety belt, the latch assembly 1 can be stored and hidden in the receiving space 201 formed by the mounting seat 2.
[0057] like Figure 1 As shown, in some embodiments of the present application, the mounting seat 2 is mounted on the frame of the seat 100 , and the mounting seat 2 is arranged at a side position of the seat 100 .
[0058] Reference Figure 3 and Figure 6 As shown, when the safety belt needs to be used, the latch assembly 1 is usually placed outside the mounting seat 2, so that the user can plug and match the buckle with the latch assembly 1. When the vehicle is hit from the side, the latch assembly 1 in the present application can be stored in the accommodating space 201, so that the collision force at the seat 100 acts on the mounting seat 2, preventing the side panel of the seat 100 from squeezing the latch assembly 1 and causing the latch assembly 1 to be unlocked or damaged. If the latch assembly 1 is damaged, there is a risk that the safety belt cannot be unlocked.
[0059] In the present application, the seat belt latch device 10 can store and hide the latch assembly 1 in the mounting seat 2 to prevent the collision force generated during a side collision from acting on the latch assembly 1 and causing damage to the latch assembly 1.
[0060] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present application, the mounting seat 2 includes a first mounting plate 221 and a second mounting plate 222, the first mounting plate 221 is used to be connected to the frame of the seat 100, and the second mounting plate 222 is arranged on the side of the first mounting plate 221 away from the frame and cooperates with the first mounting plate 221 to define the above-mentioned accommodating space 201.
[0061] It should be noted that the first mounting plate 221 and the second mounting plate 222 are both constructed as sheet metal structures with high structural strength, thereby ensuring the structural strength of the mounting base 2 and providing good protection for the components in the accommodating space 201 through the mounting base 2.
[0062] like Figure 3 As shown, in some embodiments of the present application, the first adjustment mechanism 3 includes a seat assembly 31 , a telescopic assembly 32 and a first driving assembly 33 .
[0063] Combination Figure 3 and Figure 11As shown, the seat assembly 31 is connected to the second adjustment mechanism 4, and the seat assembly 31 can move relative to the mounting seat 2 in the first direction. The telescopic assembly 32 is telescopically connected between the seat assembly 31 and the latch assembly 1 to adjust the distance between the latch assembly 1 and the seat assembly 31 through the telescopic assembly 32. Moreover, the telescopic assembly 32 is rotatably mounted on the seat assembly 31 about the first axis 101. The first drive assembly 33 is mounted on the seat assembly 31. The first drive assembly 33 is connected to the telescopic assembly 32, and the first drive assembly 33 can be used to adjust the length of the telescopic assembly 32 and drive the telescopic assembly 32 to rotate about the first axis 101. That is to say, the first drive assembly 33 has two adjustment methods for the mounting position of the latch assembly 1 relative to the seat assembly 31. First, the first drive assembly 33 can drive the telescopic assembly 32 to adjust the distance between the latch assembly 1 and the seat assembly 31. Second, the first drive assembly 33 can drive the telescopic assembly 32 to rotate relative to the seat assembly 31, so as to drive the latch assembly 1 to rotate about the first axis 101 through the telescopic assembly 32 and adjust the orientation of the latch assembly 1.
[0064] Combined with Figure 7 and Figure 11 As shown, by adjusting the length of the telescopic assembly 32, the protruding position of the latch assembly 1 relative to the mounting seat 2 can be adjusted, so as to adjust the latch assembly 1 to a position adapted to the body size of the driver and passenger.
[0065] It can be understood that after the driver and passenger plug the buckle into the latch assembly 1, the position of the latch assembly 1 can be adjusted through the first adjustment mechanism 3. For example, by shortening the length of the telescopic assembly 32 to eliminate the gap between the chest strap, waist belt and the driver and passenger, so that the seat belt can fully fit the driver and passenger, and improve the protection effect of the seat belt on the driver and passenger.
[0066] Such as Figure 3 As shown, in a further embodiment of the present application, the mounting seat 2 is provided with a guiding portion 21 extending in the first direction. The seat assembly 31 includes a slider 311 and a bearing 312. The slider 311 is slidably engaged with the guiding portion 21. The slider 311 is connected to the second adjustment mechanism 4 and is used to mount the first drive assembly 33. That is, the slider 311 is the mounting carrier of the first drive assembly 33, and the first drive assembly 33 can be driven to move synchronously relative to the mounting seat 2 through the slider 311. At the same time, the bearing 312 is sleeved on the slider 311, and the inner ring of the bearing 312 is fixedly connected to the slider 311, and the outer ring of the bearing 312 is fixedly connected to one end of the telescopic assembly 32. The central axis of the bearing 312 is the first axis 101.
[0067] Among them, the guiding part 21 can guide the sliding of the slider 311 to limit the movement path of the slider 311 relative to the mounting base 2 through the guiding part 21, and assist in adjusting the position of the slider 311 in the mounting base 2. At the same time, the slider 311 is the mounting carrier of the bearing 312 and the first driving assembly 33, and the bearing 312 and the first driving assembly 33 can be driven by the slider 311 to move synchronously relative to the mounting base 2.
[0068] Furthermore, the outer ring of the bearing 312 is sleeved on the inner ring, and the outer ring can rotate relative to the inner ring around the first axis 101. Thus, the telescopic assembly 32 is connected to the slider 311 through the bearing 312, so that the telescopic assembly 32 can rotate relative to the slider 311 around the first axis 101 to realize the angle adjustment of the plug lock assembly 1.
[0069] As Figure 3 shown, in some embodiments of the present application, the telescopic assembly 32 includes a first telescopic section 321, a second telescopic section 322, and an elastic support member (not shown in the figure).
[0070] Among them, one end of the first telescopic section 321 is fixedly connected to the outer ring of the bearing 312, and the first telescopic section 321 is formed with a receiving cavity and the other end is open. One end of the second telescopic section 322 is connected to the plug lock assembly 1, and the second telescopic section 322 can be retracted into or extended out of the receiving cavity, so as to realize the position adjustment of the plug lock assembly 1 relative to the seat assembly 31 by adjusting the position of the second telescopic section 322 relative to the first telescopic section 321.
[0071] Furthermore, the elastic support member elastically supports between the second telescopic section 322 and the first telescopic section 321, and the elastic support member can store energy when the second telescopic section 322 is retracted into the receiving cavity, so that the elastic support member has a tendency to drive the second telescopic section 322 to extend out of the receiving cavity to realize the elongation function of the telescopic assembly 32.
[0072] It can be understood that when the second telescopic section 322 is retracted into the receiving cavity, the length of the telescopic assembly 32 is shortened, and at this time, the distance between the seat assembly 31 and the plug lock assembly 1 can be reduced; when the second telescopic section 322 extends out of the receiving cavity, the length of the telescopic assembly 32 becomes longer, and at this time, the distance between the seat assembly 31 and the plug lock assembly 1 can be increased.
[0073] It should be noted that the extension or retraction of the telescopic component 32 can be achieved by the cooperation of the first driving component 33 and the elastic support member. Among them, under the action of the first driving component 33, the second telescopic section 322 can be retracted into the accommodation cavity, and the elastic support member stores energy during the above process, so that the elastic support member has a tendency to drive the second telescopic section 322 to extend out of the accommodation cavity. That is to say, when the first driving component 33 reduces the driving force applied to the second telescopic section 322, the elastic driving member can drive the second telescopic section 322 to extend out of the accommodation cavity, thereby realizing the length adjustment of the telescopic component 32.
[0074] As Figure 3 shown, in some embodiments of the present application, the telescopic component 32 further includes: at least one third telescopic section 323, the third telescopic section 323 is telescopically disposed in the accommodation cavity, and the third telescopic section 323 is sleeved on the second telescopic section 322. By adding the third telescopic section 323 between the first telescopic section 321 and the second telescopic section 322, the length adjustment range of the telescopic component 32 can be further increased.
[0075] Furthermore, the third telescopic section 323 is configured as a sleeve structure, and the third telescopic section 323 is sleeved on the second telescopic section 322. It can be understood that when only one third telescopic section 323 is provided in the telescopic component 32, one end of the third telescopic section 323 can be in limit cooperation with the first telescopic section 321 to prevent the third telescopic section 323 from disengaging from the first telescopic section 321, and the other end of the third telescopic section 323 can be in limit cooperation with the second telescopic section 322 to prevent the second telescopic section 322 from disengaging from the third telescopic section 323; when a plurality of third telescopic sections 323 are sequentially stacked and sleeved in the telescopic component 32, the outermost third telescopic section 323 is in limit cooperation with the first telescopic section 321 to prevent the third telescopic section 323 from disengaging from the first telescopic section 321, and the innermost third telescopic section 323 is in limit cooperation with the second telescopic section 322 to prevent the second telescopic section 322 from disengaging from the third telescopic section 323.
[0076] In some embodiments of the present application, the elastic support member is configured as a spring, one end of the spring is connected to the first telescopic section 321, and the other end of the spring is connected to the second telescopic section 322. Among them, the second telescopic section 322 can be formed with a direction in which the spring can be arranged in the telescopic component 32. For example, the third telescopic section 323 configured as a sleeve structure can avoid the spring (i.e., allow the spring to pass through), one end of the spring is fixed in the accommodation cavity of the first telescopic section 321, and the other end of the spring is connected to the second telescopic section 322.
[0077] In some embodiments of the present application, the first driving component 33 includes: a first driving portion 331, a winding component 332, a first flexible connecting member 333, and a second flexible connecting member 334.
[0078] Among them, the first driving part 331 is fixedly connected to the slider 311, and the winding assembly 332 is power-connected to the output end of the first driving part 331. The winding assembly 332 can be used to wind the first flexible connecting member 333 and the second flexible connecting member 334. That is to say, the first driving part 331 can drive the winding assembly 332 to wind or release the first flexible connecting member 333 and the second flexible connecting member 334, so as to transmit the driving force to the telescopic assembly 32 through the first flexible connecting member 333 and the second flexible connecting member 334, and realize the position adjustment of the telescopic assembly 32 relative to the slider 311.
[0079] As Figure 3 shown, one end of the first flexible connecting member 333 is connected to the second telescopic section 322, the other end of the first flexible connecting member 333 is connected to the winding assembly 332, and the first flexible connecting member 333 can be wound around the winding assembly 332; one end of the second flexible connecting member 334 is connected to the second telescopic section 322, the other end of the second flexible connecting member 334 is connected to the winding assembly 332, and the second flexible connecting member 334 can be wound around the winding assembly 332; among them, the first flexible connecting member 333 and the second flexible connecting member 334 are respectively arranged on both sides of the telescopic assembly 32.
[0080] It can be understood that both the first flexible connecting member 333 and the second flexible connecting member 334 are constructed as flexible connecting members. The flexible connecting member is a linear structure with a certain strength and toughness and can be wound and deformed to ensure the winding effect of the winding mechanism on the flexible connecting member. Among them, the flexible connecting member can be constructed as a metal wire (such as: steel wire, etc.), nylon thread, polyester thread, etc., and the type of the flexible connecting member is not specifically limited here.
[0081] It should be noted that the winding assembly 332 can wind the first flexible connecting member 333 and the second flexible connecting member 334 respectively. When the winding assembly 332 winds the first flexible connecting member 333 and the second flexible connecting member 334, the lengths of the first flexible connecting member 333 and the second flexible connecting member 334 between the first telescopic section 321 and the second telescopic section 322 are shortened, and the second telescopic section 322 can be retracted into the accommodating cavity of the first telescopic section 321 to realize the length adjustment of the telescopic assembly 32. Among them, when it is necessary to extend the telescopic assembly 32, the first flexible connecting member 333 and the second flexible connecting member 334 can be unwound by the winding assembly 332, and the second telescopic section 322 can extend outwards of the accommodating cavity under the action of the elastic support member.
[0082] In some embodiments of the present application, the winding assembly 332 includes: a reel, a first winding part and a second winding part. The reel is power-connected to the first driving part 331, and the reel can be driven to rotate by the first driving part 331.
[0083] Wherein, the first winding part is sleeved on the reel, and the first winding part can be selectively engaged with the reel to wind or unwind the first flexible connecting member 333 through the first winding part; the second winding part is sleeved on the reel, and the second winding part can be selectively engaged with the reel to wind or unwind the second flexible connecting member 334 through the second winding part.
[0084] When both the first winding part and the second winding part are engaged with the reel, the winding assembly 332 can wind the first flexible connecting member 333 and the second flexible connecting member 334 simultaneously; when one of the first winding part and the second winding part is engaged with the reel, the winding assembly 332 can drive the telescopic assembly 32 to rotate relative to the slider 311 about the first axis 101.
[0085] It should be noted that the first winding part and the second winding part can be constructed with the same structure. Taking the first winding part as an example, when the first winding part is engaged with the reel, the reel can drive the first winding part to rotate synchronously to achieve the winding action of the first winding part; when the first winding part is not engaged with the reel, the first winding part can rotate idly relative to the reel to achieve the unwinding action of the first flexible connecting member 333 by the first winding part.
[0086] It can be understood that the first flexible connecting member 333 and the second flexible connecting member 334 are respectively arranged on both sides of the telescopic assembly 32. When the first winding part is engaged with the reel and the second winding part is not engaged with the reel, the second winding part can unwind the second flexible connecting member 334, and further wind the first flexible connecting member 333 through the first winding part, and the telescopic assembly 32 can be driven to deflect toward the side of the first flexible connecting member 333 through the first flexible connecting member 333, that is, drive the telescopic assembly 32 to rotate about the first axis 101. Similarly, when the first winding part is not engaged with the reel and the second winding part is engaged with the reel, the first winding part can unwind the first flexible connecting member 333, and further wind the second flexible connecting member 334 through the second winding part, and the telescopic assembly 32 can be driven to deflect toward the side of the second flexible connecting member 334 through the second flexible connecting member 334, that is, drive the telescopic assembly 32 to rotate about the first axis 101, and the rotation direction of the telescopic assembly 32 is opposite to the rotation direction of the telescopic assembly 32 when the first driving mechanism is in the working condition that the first winding part is engaged with the reel and the second winding part is not engaged with the reel. Thus, the angle adjustment of the plug lock assembly 1 can be realized.
[0087] In some embodiments of the present application, the first driving part 331 is constructed as a driving motor, and the output end of the first driving part 331 can be constructed as a motor shaft.
[0088] It can be understood that by configuring the first winding portion and the second winding portion to be selectively engageable with the reel, the number of driving devices in the first driving mechanism can be reduced, that is, there is no need to provide two driving devices to respectively drive the first winding portion and the second winding portion to act, making the component layout in the seat belt latch device 10 compact and saving space.
[0089] In some embodiments of the present application, the slider 311 is formed with a threaded hole, and the slider 311 is provided with a second adjusting mechanism 4 including a driving rod 41 and a second driving portion 42. The driving rod 41 is provided with a threaded section, and the threaded section is in threaded cooperation with the threaded hole. The second driving portion 42 is fixed on the mounting seat 2, and the second driving portion 42 is connected to the driving rod 41. The second driving portion 42 is used to drive the driving rod 41 to rotate, so as to realize the position adjustment of the slider 311 in the first direction through the threaded cooperation between the driving rod 41 and the slider 311.
[0090] It should be noted that the slider 311 is slidably engaged with the guiding portion 21 provided on the mounting seat 2. Under the action of the guiding portion 21, the rotation of the slider 311 can be restricted. Thus, when the driving rod 41 rotates, the threaded section is in threaded cooperation with the threaded hole to drive the slider 311 to slide in the first direction, realizing the position adjustment of the slider 311 relative to the mounting seat 2 in the first direction.
[0091] In some embodiments of the present application, a chute is provided on the slider 311, and the guiding portion 21 is configured as a slide rail, and at least part of the slide rail is embedded in the chute to guide the slider 311.
[0092] The seat belt latch device 10 according to the embodiments of the present application can adjust the position of the latch assembly 1 according to the real-time working conditions of the vehicle, so as to improve the protection effect of the seat belt on the driver and passengers.
[0093] Refer to Figure 4 and Figure 5 As shown, when the vehicle is in a stationary state (i.e., the seat belt is not needed), the latch assembly 1 can be received in the mounting seat 2.
[0094] Among them, the adjustment method of the latch assembly 1 may include the following actions:
[0095] (1) Drive the driving rod 41 to rotate through the second driving portion 42, and adjust the seat assembly 31 to a position suitable for receiving the latch assembly 1;
[0096] (2) The first driving part 331 winds up and tightens the first flexible connecting part 333 and the second flexible connecting part 334 to shorten the length of the telescopic assembly 32 (i.e., at least part of the second telescopic section 322 is received in the accommodation cavity of the first telescopic section 321), and the first driving part 331 cooperates with the winding assembly 332 to further drive the telescopic assembly 32 to rotate, so as to adjust the telescopic assembly 32 and the latch assembly 1 to an angle suitable for being received in the mounting seat 2.
[0097] It should be noted that the above actions (1) and (2) can be carried out synchronously or sequentially according to the current state of the latch assembly 1, and no specific limitation is made here. At the same time, the above working conditions can be judged by the vehicle controller obtaining corresponding information, such as: the seat 100 processor (SCU: System Control Units) detects that the current vehicle speed is 0 and the door is closed and locked, etc.
[0098] Refer to Figure 6 and Figure 7 As shown, when the driver and passenger need to use the seat belt, the latch assembly 1 can be adjusted to the extended position so that the driver and passenger can plug the buckle into the latch assembly 1 for cooperation.
[0099] Among them, the adjustment method of the latch assembly 1 may include the following actions:
[0100] (1) The first driving part 331 cooperates with the winding assembly 332 to adjust the angle of the latch assembly 1, and adaptively relaxes the first flexible connecting part 333 and the second flexible connecting part 334 according to the length adjustment requirement of the telescopic assembly 32, so as to drive the telescopic assembly 32 to extend through the elastic support member (i.e., the second telescopic section 322 extends out of the accommodation cavity of the first telescopic section 321);
[0101] (2) The second driving part 42 drives the driving rod 41 to rotate to adjust the seat assembly 31 to the corresponding position.
[0102] It should be noted that the above actions (1) and (2) can be carried out synchronously or sequentially according to the current state of the latch assembly 1, and no specific limitation is made here. At the same time, the above working conditions can be judged by the vehicle controller obtaining corresponding information, such as: detecting information such as the vehicle is unlocked and the door is opened.
[0103] Combined with Figure 2 and Figure 6 As shown, when the driver and passenger plug the buckle into the latch assembly 1 for cooperation, the position of the latch assembly 1 can be further adjusted through the seat belt latch device 10 to improve the matching effect between the seat belt and the driver and passenger.
[0104] Among them, the adjustment method of the latch assembly 1 may include the following actions:
[0105] (1) The second driving part 42 drives the driving rod 41 to rotate so as to adaptively adjust the position of the seat assembly 31 relative to the mounting seat 2;
[0106] (2) The first driving part 331 cooperates with the winding assembly 332 to adaptively adjust the telescopic length of the telescopic assembly 32.
[0107] It should be noted that the above-mentioned actions (1) and (2) can be performed simultaneously or sequentially according to the current state of the latch assembly 1, and are not specifically limited here. In this way, the gap between the chest belt, the waist belt and the driver and the passenger can be eliminated, so as to further enhance the protective effect of the seat belt on the driver and the passenger.
[0108] It is understandable that when the vehicle detects that the driver or passenger needs to get off the vehicle (such as: the vehicle speed is 0 and the vehicle's ignition switch is switched to the off position), the latch assembly 1 can be adjusted to a position that is convenient for the driver or passenger to operate. The adjustment method is opposite to the above action and will not be repeated here.
[0109] When the vehicle is about to collide, the position of the latch assembly 1 can be adjusted according to the collision information (such as head-on collision, side collision, etc.) and the body information of the driver and passenger. The specific adjustment is as follows:
[0110] When the vehicle has a far-side collision (i.e., the collision direction is the side of the seat 100 away from the seat belt latch device 10), the in-vehicle camera determines the sitting posture and body shape of the occupant in the vehicle, and the SCU determines whether the latch assembly 1 is located at the pelvis and thigh position of the occupant based on the latch angle and height signal. If the latch assembly 1 is not at the pelvis and thigh position, the latch assembly 1 will not be moved; if the latch assembly 1 is in the pelvis and thigh area of the occupant, the SCU sends an electrical signal to the seat belt latch device 10 to drive the latch assembly 1 to move outside the pelvis and thigh area.
[0111] When the vehicle is likely to have a head-on collision, the seat 100 processor can analyze whether a head-on collision has occurred based on the electrical signal of the external sensor. The position of the latch assembly 1 is adjusted based on the analysis result. If the vehicle does not have a head-on collision, the latch assembly 1 is not moved; if it is detected that the vehicle is about to have a head-on collision, the in-vehicle camera determines the sitting posture and body shape of the occupants in the vehicle, and the SCU sends an electrical signal to the seat belt latch device 10 to adjust the position of the latch assembly 1 based on the input latch angle and height signal, such as: moving the latch assembly 1 from Figure 11 Switch to Figure 9 to tighten the seat belt to prevent the occupant from diving during a collision.
[0112] In summary, the seat belt locking device 10 according to the embodiment of the present application has at least the following advantages:
[0113] (1) When a frontal collision occurs to the vehicle, the seat belt latch device 10 can prevent the driver and passengers from diving by adjusting the position of the latch assembly 1, improving the protection effect of the seat belt on the driver and passengers;
[0114] (2) When a side collision occurs to the vehicle, the seat belt latch device 10 can adjust the latch assembly 1 to an area suitable for avoiding the pelvis and thigh positions of the driver and passengers by adjusting the position of the latch assembly 1, reducing the injury caused by the latch assembly 1 to the driver and passengers;
[0115] (3) The position of the latch assembly 1 can be adaptively adjusted according to the usage requirements of the driver and passengers, so as to facilitate the user to use the seat belt, and the position of the latch assembly 1 can be further adjusted after the user plugs the buckle into the latch assembly 1, eliminating the gap between the waist belt, chest belt and the driver and passengers, and enhancing the protection effect of the seat belt on the driver and passengers.
[0116] The vehicle according to an embodiment of the present application includes the above-mentioned seat belt latch device 10, and the seat belt latch device 10 can further improve the safety of the vehicle and enhance the driving experience of the driver and passengers.
[0117] The vehicle and the above-mentioned seat belt latch device 10 have the same advantages as those of the prior art, which will not be elaborated here.
[0118] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
