Description

Seatbelt buckles, seats and vehicles

[0001] This application claims priority to Chinese Patent Application No. 202421604456.4, filed on July 8, 2024, entitled "Seatbelt Buckle, Seat and Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of seat belt technology, and in particular to a seat belt buckle, seat, and vehicle. Background Technology

[0003] Seat belts are a type of safety device used in vehicles to protect occupants. A seat belt typically includes a belt body, a buckle, and a buckle. The buckle is threaded through the belt body and engages with the buckle. The belt body restrains the occupants while they are seated.

[0004] To facilitate the insertion of the seatbelt insert into the seatbelt buckle in low-light conditions, related technologies have incorporated a seatbelt buckle that includes a housing and a light guide. The light guide has a light-emitting section that surrounds the housing circumferentially. However, in these related technologies, the light-emitting section is prone to uneven brightness at different locations. Summary of the Invention

[0005] This application provides a seat belt buckle, a seat, and a vehicle, which can make the light emission section of the light guide on the seat belt buckle more uniform.

[0006] A first aspect of this application provides a seatbelt buckle, which includes a housing, a light guide fixing member, a first light guide, and a light source. The housing includes a plug-in end located at one end of the housing in a first direction. The plug-in end has an open structure, and the light source is disposed within the housing. The light guide fixing member is disposed at the plug-in end and is fixedly connected to the housing. The light guide fixing member includes a first portion and a second portion, which are used to enclose a mounting opening communicating with the inner cavity of the housing. One end of the first portion and one end of the second portion are located on one side of the mounting opening in a second direction, and the other ends of the first portion and the second portion are located on the other side of the mounting opening in the second direction. The first light guide includes a first light emitting section and a first light guiding section. One end of the first light guiding section is connected to one end of the first light emitting section, and the other end of the first light guiding section faces the light source. The light source emits light into the first light guiding section at the end opposite to the first light emitting section. The first light emitting section is disposed in the first portion. The first direction is perpendicular to the second direction.

[0007] The seatbelt buckle provided in this application embodiment has a smaller circumferential dimension in the first part of the housing. This allows for a shorter length of the first light-emitting segment within the first part, resulting in less light loss during propagation and improving the uniformity of light emission from the first light-emitting segment. Furthermore, the fewer corners in the first part reduce the number of corners in the first light-emitting segment, further minimizing light loss and improving the uniformity of light emission. Additionally, fewer corners in the first light-emitting segment also reduce the likelihood of breakage and light leakage due to breakage, further enhancing the uniformity of light emission.

[0008] In one possible implementation, the number of bends in the first light-emitting segment is less than or equal to two. This results in less light loss during propagation within the first light-emitting segment, and also reduces the risk of breakage in the first light-emitting segment.

[0009] In one possible implementation, the first part includes side sections extending at both ends along a second direction, with the side sections located on the side of the mounting opening facing a third direction. A first light-emitting section is disposed on the side sections. One of the second and third directions is the width direction of the housing, and the other is the height direction of the housing. The third direction is perpendicular to both the second and first directions. This allows for a shorter length and fewer corners in the first light-emitting section, which helps improve the uniformity of light emission from the first light-emitting section.

[0010] In one possible implementation, at least a portion of the first part is a light-transmitting area, and a first light-emitting segment is disposed in the light-transmitting area, with the first light-emitting segment located on the side of the first part facing the inner cavity of the housing. In this way, the first part can protect the first light-emitting segment, making it less susceptible to damage from impacts.

[0011] In one possible implementation, the first part has a snap-fit ​​structure on the side facing the inner cavity of the housing, and the first light-emitting segment is snapped into the snap-fit ​​structure. This facilitates the connection between the first light-emitting segment and the first part.

[0012] In one possible implementation, the first portion has a socket that communicates with the inner cavity of the housing. Thus, a first light-emitting segment is positioned near the socket, facilitating the emission of light by indicating the location of the socket.

[0013] In one possible implementation, the second part has a socket plate that connects to the inner cavity of the housing. Thus, the arrangement of the first light-emitting section is not limited by the socket plate, allowing for more flexible arrangement of the first light-emitting section.

[0014] In one possible implementation, the first part and the second part are separate structures. The first part and the second part are respectively fixedly connected to the housing. In this way, the degree of bending required when the light guide is assembled onto the light guide fixing component is minimized, and the light guide is less likely to break during the assembly process.

[0015] In one possible implementation, the seatbelt buckle further includes a second light guide. The second light guide includes a second light emitting section and a second light guiding section, with the second light emitting section connected to the second light guiding section, and the second light emitting section is located in the second part. This allows for a larger light-emitting area on the light guide fixing member, facilitating illumination around the insertion slot. Furthermore, both the first and second light emitting sections are relatively short in length and have fewer corners, resulting in more uniform light emission from both sections.

[0016] In one possible implementation, one end of the second light-guiding section is connected to one end of the second light-emitting section, and the other end of the second light-guiding section and the end of the first light-guiding section away from the first light-emitting section face the same light source. The light source injects light into the end of the first light-guiding section away from the first light-emitting section and the end of the second light-guiding section away from the second light-emitting section.

[0017] In one possible implementation, the plug-in end is provided with a first light-blocking portion and a second light-blocking portion, which are respectively located on both sides of the plug-in end in a second direction. The first portion is located on one side of the first and second light-blocking portions in a third direction, and the second portion is located on the other side of the first and second light-blocking portions in the third direction. The first portion, the first light-blocking portion, the second portion, and the second light-blocking portion surround and form a mounting opening. In this way, the first and second light-blocking portions can block the light emitted by the first and second light-emitting segments to form two non-light-emitting positions, which facilitates the positioning of the plug-in socket.

[0018] In one possible implementation, the housing includes a first cover and a second cover. The first cover is fitted over the third-party-facing side of the second cover. A first light-blocking portion and a second light-blocking portion are fixedly connected to the first cover. One of the first and second cover covers is fixedly connected to a first part, and the other of the first and second cover covers is fixedly connected to a second part. This facilitates the assembly of the first light-blocking portion, the second light-blocking portion, the first part, and the second part.

[0019] In one possible implementation, the seatbelt buckle further includes a button and a locking mechanism. The locking mechanism is disposed within the housing, and the button is disposed within the mounting opening, facilitating the installation of the light guide fixing member and the button for triggering the locking mechanism. The locking mechanism engages with the seatbelt insert plate to achieve a locking connection between the seatbelt insert plate and the seatbelt buckle, allowing the seatbelt to restrain the occupant in the seat. The button, pressed to a preset position, disengages the engaged seatbelt insert plate from the locking mechanism, thereby releasing the seatbelt from the seatbelt and releasing the occupant from the restraint of the seatbelt.

[0020] In one possible implementation, the seatbelt buckle further includes a detection device disposed on the locking mechanism. The detection device is used to detect the engagement state of the locking mechanism. The engagement state includes a state where the seatbelt insert is engaged and a state where the seatbelt insert is not engaged. This facilitates understanding the engagement state of the locking mechanism, enabling related control based on the engagement state of the locking mechanism.

[0021] In one possible implementation, the light source is a variable-color light source. Thus, by changing the color of the light source, different information can be provided to the user, or different environmental effects can be created.

[0022] A second aspect of this application provides a seat that includes a seatbelt buckle as described in any of the above embodiments.

[0023] A third aspect of this application provides a means of transportation that includes a seatbelt buckle as described in any of the above embodiments. Attached Figure Description

Detailed Implementation

[0040] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] This application provides a means of transportation, which may include, but is not limited to, automobiles, trains, airplanes, ships, etc.

[0042] In this embodiment of the application, the vehicle may include a vehicle body and one or more seats, the seats including a seat body for passengers to sit on, the seat body being disposed on the vehicle body.

[0043] For example, the means of transportation is a car, and the main body of the means of transportation is the car body.

[0044] For example, the means of transportation is an airplane, and the main body of the means of transportation is the fuselage.

[0045] In this embodiment of the application, the vehicle may include a seat belt, which may include a seat belt body, a seat belt insert, and a seat belt buckle. The seat belt insert is inserted through the seat belt body and is used to engage with the seat belt buckle. The seat belt body can be used to restrain the occupants sitting in the seat.

[0046] In some examples, one or more seatbelt buckles can be installed on the main body of the device. For example, when the vehicle is a car, the seatbelt buckles for the rear seats can be installed on the vehicle body.

[0047] In some examples, one or more seats may include seatbelt buckles, which may be located on the seat body. For example, in a car, the front seats of the car may include seatbelt buckles, which may be located on the seat body.

[0048] In some examples, one or more seat belt straps can be installed on the main body of the vehicle. For example, when the vehicle is a car, one or more seat belt straps can be installed on the car body.

[0049] In some examples, one or more seats may include seat belt bodies, which may be mounted on the seat body. For example, in the case of an airplane, the seats may include seat belt bodies.

[0050] Figure 1 is a schematic diagram of a seat belt buckle provided in an embodiment of this application, and Figure 2 is an exploded view of a seat belt buckle provided in an embodiment of this application. In the figures, the x-direction is the length direction of the housing, the y-direction is the width direction of the housing, and the z-direction is the height direction of the housing. The length direction of the housing is perpendicular to the width direction of the housing, the length direction of the housing is perpendicular to the height direction of the housing, and the width direction of the housing is perpendicular to the height direction of the housing.

[0051] As shown in Figures 1 and 2, in this embodiment of the application, the seat belt buckle includes a housing 100 and a steel cable 320. The housing 100 is connected to the steel cable 320, which is used to connect to the chair body or the tool body to set the seat belt buckle on the chair body or the tool body.

[0052] The housing 100 includes a plug-in end and a connecting end, which are located at both ends of the housing 100 in a first direction. The steel cable 320 is disposed at the connecting end. The plug-in end has an open structure and is used for inserting a portion of the seat belt insert into the housing 100. The first direction is the length direction of the housing 100, that is, the length direction of the housing 100 is the direction in which the seat belt insert is inserted and removed. The width direction and the height direction of the housing 100 are perpendicular to the insertion and removal direction of the seat belt insert.

[0053] For example, the width of housing 100 is greater than the height of housing 100.

[0054] In some examples, the length of housing 100 may be greater than the width of housing 100.

[0055] In other examples, the length of housing 100 may be less than the width of housing 100, and the height of housing 100 may be less than the length of housing 100.

[0056] For example, the connecting end has a connection port communicating with the inner cavity of the housing 100. The steel cable 320 passes through the connection port. The housing 100 may have a connecting structure for connecting with the steel cable 320. A portion of the steel cable 320 extends into the housing 100 through the connection port and connects with the connecting structure inside the housing 100. This facilitates a secure connection between the steel cable 320 and the housing 100. Furthermore, since the connecting structure is located inside the housing 100, it is less likely to collide with occupants and cause injury.

[0057] In this embodiment, the seat belt buckle also includes a locking mechanism 330. The locking mechanism 330 is disposed inside the housing 100. A portion of the seat belt insert can be inserted into the housing 100 through the plug end. The locking mechanism 330 is used to engage with the seat belt insert to facilitate the engagement connection between the seat belt insert and the seat belt buckle, so that the seat belt can restrain the driver and passenger sitting on the seat.

[0058] In this embodiment, the seat belt buckle also includes a button 310. The button 310 is disposed at the insertion end. When the button 310 is pressed to a preset position, it is used to disengage the engaged seat belt insert from the locking mechanism 330, so as to release the seat belt insert from the seat belt buckle and release the restraint of the seat belt on the driver and passenger sitting on the seat.

[0059] In some possible implementations, the housing 100 includes a first cover 110 and a second cover 120, with the first cover 110 and the second cover 120 covering each other to enclose the inner cavity of the housing 100, making it easier to install components such as a locking mechanism 330 inside the housing 100.

[0060] To facilitate the insertion of the seatbelt insert into the seatbelt buckle in low-light conditions such as at night, the seatbelt buckle may also include a light guide and a light source in related technologies. The light guide includes a connected light emitting section and a light guiding section. The light emitting section surrounds the periphery of the housing, and the light source emits light towards the light guiding section. The light guiding section guides the light to be emitted from the light emitting section.

[0061] However, in related technologies, the light emission section is relatively long and has many bends, resulting in greater light loss during propagation and a higher risk of breakage. This makes it easy for uneven brightness to occur at different locations within the light emission section.

[0062] Figure 3 is a schematic diagram of the first light guide of a seat belt buckle provided in an embodiment of this application, and Figure 4 is a schematic diagram of a seat belt buckle with a light guide fixing member at one end provided in an embodiment of this application.

[0063] As shown in Figures 3 and 4, and referring to Figures 1 and 2, based on this, in the embodiment of this application, the seat belt buckle also includes a light guide fixing member 200, a first light guide 500 and a first light source 340. The first light source 340 is disposed inside the housing 100, the light guide fixing member 200 is disposed at the plug-in end, and the light guide fixing member 200 is fixedly connected to the housing 100.

[0064] The optical guide fixing member 200 includes a first part 210 and a second part 220. The first part 210 and the second part 220 are used to enclose a mounting opening 410 that communicates with the inner cavity of the housing 100. One end of the first part 210 and one end of the second part 220 are located on one side of the mounting opening 410 in a second direction, and the other end of the first part 210 and the other end of the second part 220 are located on the other side of the mounting opening 410 in the second direction. The first part 210 and the second part 220 are arranged opposite to each other along a third direction, wherein one of the second direction and the third direction is the width direction of the housing 100, and the other of the second direction and the third direction is the height direction of the housing 100.

[0065] The first light guide 500 includes a first light emitting section 510 and a first light guiding section 520. One end of the first light guiding section 520 is connected to one end of the first light emitting section 510, and the other end of the first light guiding section 520 faces the first light source 340. The first light source 340 emits light into the end of the first light guiding section 520 away from the first light emitting section 510. The first light emitting section 510 is located in the first part 210, that is, the first light emitting section 510 does not extend to the second part 220.

[0066] In this way, the smaller circumferential dimension of the first portion 210 along the housing 100 allows for a shorter length of the first light-emitting section 510, resulting in less light loss during propagation within the first light-emitting section 510 and improving the uniformity of light emission. Furthermore, fewer corners in the first portion 210 reduce light loss during propagation within the first light-emitting section 510, further enhancing the uniformity of light emission. Additionally, fewer corners also reduce the likelihood of breakage in the first light-emitting section 510, minimizing light leakage and further improving the uniformity of light emission.

[0067] After light enters the first light guide 500 from the first light guide section 520, it is guided by the first light guide section 520 to the first light emission section 510. The light then exits the first light guide 500 through the first light emission section 510, causing the first light emission section 510 to emit light.

[0068] For example, one end of the first light-introducing section 520 away from the first light-emitting section 510 may be located inside the housing 100.

[0069] For example, the light guide fixing component 200 can be fixedly connected to the housing 100 by means of snap-fit, fastener connection, bonding, welding, etc.

[0070] In some examples, the second direction is the width direction of the housing 100, and the third direction is the height direction of the housing 100. That is, one end of the first part 210 and one end of the second part 220 are located on one side of the mounting opening 410 in the width direction of the housing 100, and the other end of the first part 210 and the other end of the second part 220 are located on the other side of the mounting opening 410 in the width direction of the housing 100. The width of the housing 100 is greater than the height of the housing 100.

[0071] In some possible implementations, the button 310 is disposed within the mounting port 410, making it easier to install the light guide fixing member 200 and the button 310 for triggering the locking mechanism 330.

[0072] In some possible implementations, the light guide fixing member 200 has an insert plate socket 420 communicating with the inner cavity of the housing 100. The insert plate socket 420 is used for a portion of the seat belt insert plate to be inserted into the housing 100, and the first light emitting segment 510 indicates the position of the insert plate socket 420.

[0073] In some examples, the insert 420 communicates with the mounting port 410. This allows for a more compact arrangement of the seatbelt buckle components, which helps to reduce the size of the seatbelt buckle.

[0074] In some possible implementations, the number of corners in the first ray-emitting segment 510 is less than or equal to two.

[0075] In this way, the light loss during propagation within the first light-emitting section 510 is small, and the risk of breakage of the first light-emitting section 510 is also small.

[0076] In this embodiment of the application, the first part 210 includes a first side segment 211 extending at both ends along a second direction, and the first side segment 211 is located on the third-direction side of the mounting port 410.

[0077] In some examples, the first side segment 211 is connected to the second part 220 at both ends in the second direction.

[0078] In other examples, the first part 210 also includes a first protruding section 212 and a second protruding section 213, which are respectively connected to the two ends of the first side section 211 in the second direction. The first protruding section 212 and the second protruding section 213 are respectively located on both sides of the mounting port 410 in the second direction. The first protruding section 212 and the second protruding section 213 both protrude from the first side section 211 towards the second part 220 in the third direction. The end of the first protruding section 212 away from the first side section 211 and the end of the second protruding section 213 away from the first side section 211 are connected to the second part 220.

[0079] In this embodiment of the application, the second part 220 includes a second side segment 221 extending at both ends along a second direction, and the first side segment 211 and the second side segment 221 are respectively located on both sides of the mounting port 410 in a third direction.

[0080] In some examples, the two ends of the second side segment 221 are connected to the first portion 210 in the second direction. For example, the two ends of the second side segment 221 in the second direction are connected to the end of the first extension segment 212 opposite to the first side segment 211 and the end of the second extension segment 213 opposite to the first side segment 211, respectively.

[0081] In some examples, the second part 220 also includes a third protruding section 222 and a fourth protruding section 223, which are respectively connected to the two ends of the second side section 221 in the second direction. The third protruding section 222 and the fourth protruding section 223 are respectively located on both sides of the mounting port 410 in the second direction. The third protruding section 222 and the fourth protruding section 223 both protrude from the second side section 221 towards the first part 210 in the third direction. The end of the third protruding section 222 away from the second side section 221 and the end of the fourth protruding section 223 away from the second side section 221 are connected to the first part 210. For example, the end of the third extension segment 222 away from the second side segment 221 and the end of the fourth extension segment 223 away from the second side segment 221 are respectively connected to the two ends of the first side segment 211 in the second direction; or, the end of the third extension segment 222 away from the second side segment 221 is connected to the end of the first extension segment 212 away from the first side segment 211, and the end of the fourth extension segment 223 away from the second side segment 221 is connected to the end of the second extension segment 213 away from the first side segment 211.

[0082] As shown in Figure 4, in some possible embodiments, the first light-emitting section 510 extends from the first protruding section 212 along the circumference of the housing 100 to the second protruding section 213. That is, the two ends of the first light-emitting section 510 are located at the first protruding section 212 and the second protruding section 213, respectively. The first light-emitting section 510 is disposed at the first protruding section 212, the first side section 211, and the second protruding section 213. In this way, the light-emitting area on the light guide fixing member 200 can be larger, which is convenient for illuminating the area around the insertion plate socket 420.

[0083] In some examples where the second direction is the width direction of the housing 100 and the third direction is the height direction of the housing 100, the first protruding section 212 and the second protruding section 213 are respectively located on both sides of the mounting port 410 in the width direction of the housing 100, and the first light emitting section 510 extends from one side of the mounting port 410 in the width direction of the housing 100 to the other side of the mounting port 410 in the width direction of the housing 100.

[0084] Figure 5 is a schematic diagram of another type of seat belt buckle with a light guide fixing component provided in an embodiment of this application.

[0085] As shown in Figure 5, in some other possible embodiments, the first light emitting section 510 is disposed on the first side section 211, that is, the first light emitting section 510 is located on the side of the mounting port 410 facing the third direction.

[0086] This allows the first light-emitting segment 510 to be shorter and have fewer corners, which helps to improve the uniformity of light emission from the first light-emitting segment 510.

[0087] In the example where the first portion 210 includes a first extension 212 and a second extension 213, the first light emitting segment 510 being located on the first side segment 211 means that the first light emitting segment does not extend to the first extension 212 and the second extension 213.

[0088] For example, the first ray emitting segment 510 can be a straight line segment or an arc segment.

[0089] In some examples where the second direction is the width direction of the housing 100 and the third direction is the height direction of the housing 100, the first light emitting segment 510 is located on one side of the mounting port 410 in the height direction of the housing 100.

[0090] In some possible implementations, the first portion 210 has a plate socket 420 communicating with the inner cavity of the housing 100, that is, the plate socket 420 is located in the first portion 210.

[0091] In this way, the first light emitting segment 510 is close to the socket 420, which is conducive to the first light emitting segment 510 indicating the position of the socket 420.

[0092] For example, the insert socket 420 is located on the first side segment 211, and the insert socket 420 and the first light emitting segment 510 are located on the same side of the mounting port 410 in the third direction.

[0093] For example, the first light emitting segment 510 is disposed opposite to the plug-in socket 420 in a third direction so that the light emitting segment 510 indicates the position of the plug-in socket 420.

[0094] Figure 6 is a schematic diagram of another type of seat belt buckle with a light guide fixing component provided in an embodiment of this application.

[0095] As shown in Figure 6, in some other possible embodiments, the second part 220 has a plate socket 420 communicating with the inner cavity of the housing 100, that is, the plate socket 420 is located in the second part 220. In this way, the arrangement of the first light emitting section 510 is not limited by the plate socket 420, and the arrangement of the first light emitting section 510 can be more flexible.

[0096] For example, the insert socket 420 is located on the second side section 221, and the mounting port 410 is located between the first light emitting section 510 and the insert socket 420.

[0097] In some examples where the socket 420 is located in the second part 220, both ends of the first light emitting section 510 may extend to the first extension section 212 and the second extension section 213.

[0098] Figure 7 is a schematic diagram of another type of seat belt buckle with a light guide fixing component at one end, provided in an embodiment of this application.

[0099] In some other examples where the socket 420 is located in the second part 220, the first light emitting segment 510 may be provided in the first side segment 211. The first light emitting segment 510 and the socket 420 are provided opposite to each other in the third direction. The first light emitting segment 510 and the socket 420 are respectively located on both sides of the mounting port 410 in the third direction.

[0100] Figure 8 is a schematic diagram of another type of seat belt buckle with a light guide fixing component provided in an embodiment of this application.

[0101] As shown in Figure 8, in some examples, the second direction is the height direction of the housing 100, and the third direction is the width direction of the housing 100. That is, one end of the first part 210 and one end of the second part 220 are located on one side of the mounting opening 410 in the height direction of the housing 100, and the other ends of the first part 210 and the second part 220 are located on the other side of the mounting opening 410 in the height direction of the housing 100. The width of the housing 100 is greater than the height of the housing 100. In this case, the insert socket 420 can be formed by the first part 210 and the second part 220.

[0102] In some possible implementations, at least a portion of the first part 210 is a light-transmitting area, and a first light-emitting segment 510 is disposed in the light-transmitting area of ​​the first part 210, with the first light-emitting segment 510 disposed on the side of the first part 210 facing the inner cavity of the housing 100.

[0103] In this way, the first part 210 can protect the first light emitting section 510, making the first light emitting section 510 less susceptible to damage from collisions.

[0104] In some possible implementations, the first portion 210 has a first snap-fit ​​structure (not shown) on the side facing the inner cavity of the housing 100, and the first light emitting segment 510 is snapped into the first snap-fit ​​structure.

[0105] In this way, the connection between the first light emission section 510 and the first part 210 is relatively convenient.

[0106] For example, the first snap-fit ​​structure may include, but is not limited to, a slot structure, a claw structure, etc.

[0107] In some examples, the first part 210 includes a first fixing structure (not shown) and a first cover plate (not shown). The first fixing structure is made of a non-transparent material, and the first cover plate is made of a transparent material. The first fixing structure has a first strip-shaped through hole, which is the light-transmitting area of ​​the first part 210. A first light emitting segment 510 is disposed at the first strip-shaped through hole. The first cover plate is attached to the first fixing structure, and the first cover plate covers the first strip-shaped through hole and blocks the first light emitting segment 510.

[0108] For example, the first cover plate may be, but is not limited to, an acrylic plate, a glass plate, etc.

[0109] For example, the first cover plate can be fixedly connected to the first fixed structure through processes such as bonding or welding.

[0110] For example, the first snap-fit ​​structure is disposed on the first fixed structure, and the first light emitting segment 510 is disposed on the first fixed structure through the first snap-fit ​​structure.

[0111] In other examples, the first part 210 is made of a light-transmitting material, and all of the first part 210 is a light-transmitting area.

[0112] Figure 9 is an exploded view of another seat belt buckle provided in an embodiment of this application; Figure 10 is a schematic diagram of a second light guide of a seat belt buckle provided in an embodiment of this application; Figure 11 is a schematic diagram of a seat belt buckle provided in an embodiment of this application with a light guide fixing member at one end.

[0113] As shown in Figures 9-11, in some possible embodiments, the seat belt buckle further includes a second light guide 600, which includes a second light emitting section 610 and a second light guiding section 620. The second light emitting section 610 is connected to the second light guiding section 620, and the second light emitting section 610 is disposed in the second part 220. The first light source 340 or other light sources can emit light into the second light guiding section 620.

[0114] This allows for a larger light-emitting area on the light guide fixing component 200, facilitating the illumination of the area around the insertion plate socket 420. Furthermore, both the first light-emitting segment 510 and the second light-emitting segment 610 are relatively short in length and have fewer corners, resulting in more uniform light emission from both.

[0115] After light enters the second light guide 600 from the second light guide section 620, it is guided by the second light guide section 620 to the second light emission section 610. The light then exits the second light guide 600 through the second light emission section 610, causing the second light emission section 610 to emit light.

[0116] In some possible implementations, the first part 210 and the second part 220 are separate structures, and the first part 210 and the second part 220 are respectively fixedly connected to the housing 100.

[0117] In this way, the connection between the first light-emitting segment 510 and the first part 210 is relatively convenient, the degree of bending required for the first light guide 500 when it is assembled onto the first part 210 is small, and the first light guide 500 is less likely to break during the assembly process. When the seat belt buckle includes the second light guide 600, the connection between the second light-emitting segment 610 and the second part 220 is also relatively convenient, the degree of bending required for the second light guide 600 when it is assembled onto the second part 220 is small, and the second light guide 600 is less likely to break during the assembly process.

[0118] One of the first cover 110 and the second cover 120 is fixedly connected to the first part 210, and the other of the first cover 110 and the second cover 120 is fixedly connected to the second part 220.

[0119] For example, one of the first cover 110 and the second cover 120 can be fixedly connected to the first part 210 by means of snap-fit, fastener connection, bonding, welding, etc., and the other of the first cover 110 and the second cover 120 can be fixedly connected to the second part 220 by means of snap-fit, fastener connection, bonding, welding, etc.

[0120] In some possible embodiments, the plug-in end is provided with a first light-blocking portion 130 and a second light-blocking portion 140, which are respectively located on both sides of the plug-in end in a second direction. A first portion 210 is located on one side of the first light-blocking portion 130 and the second light-blocking portion 140 in a third direction, and a second portion 220 is located on the other side of the first light-blocking portion 130 and the second light-blocking portion 140 in a third direction. The first portion 210, the first light-blocking portion 130, the second portion 220, and the second light-blocking portion 140 surround and form a mounting opening 410.

[0121] In this way, the first light-blocking part 130 and the second light-blocking part 140 can block the light emitted by the first light-emitting section 510 and the second light-emitting section 610 to form two non-light-emitting positions, so as to facilitate the positioning of the plug-in socket 420.

[0122] For example, the first light-blocking part 130 is located between the first extension section 212 and the third extension section 222, and the second light-blocking part 140 is located between the second extension section 213 and the fourth extension section 223.

[0123] In some possible implementations, the first cover 110 covers the second cover 120 on the third-facing side, and the first light-blocking part 130 and the second light-blocking part 140 are fixedly connected to the first cover 110.

[0124] In this way, the first light-blocking part 130, the second light-blocking part 140, the first part 210 and the second part 220 are easier to assemble.

[0125] For example, the first light-blocking part 130 and the second light-blocking part 140 are integral with the first cover 110.

[0126] In some other possible implementations, the first part 210 and the second part 220 may be an integral structure.

[0127] In this way, the connection between the light guide fixing component 200 and the housing 100 is relatively convenient.

[0128] In some possible implementations, at least a portion of the second part 220 is a light-transmitting area, and a second light-emitting segment 610 is disposed in the light-transmitting area of ​​the second part 220, with the second light-emitting segment 610 disposed on the side of the second part 220 facing the inner cavity of the housing 100.

[0129] In this way, the second part 220 can protect the second light emitting section 610, making the second light emitting section 610 less susceptible to damage from collisions.

[0130] In some possible implementations, the second portion 220 has a second snap-fit ​​structure (not shown) on the side facing the inner cavity of the housing 100, and the second light emitting segment 610 is snapped into the second snap-fit ​​structure.

[0131] In this way, the connection between the second light emitting section 610 and the second part 220 is relatively convenient.

[0132] For example, the second snap-fit ​​structure may include, but is not limited to, a slot structure, a claw structure, etc.

[0133] In some examples, the second part 220 includes a second fixing structure (not shown) and a second cover plate (not shown). The second fixing structure is made of a non-transparent material, and the second cover plate is made of a transparent material. The second fixing structure has a second strip-shaped through hole, which is the light-transmitting area of ​​the second part 220. A second light emitting section 610 is disposed at the second strip-shaped through hole. The second cover plate is attached to the second fixing structure, and the second cover plate covers the second strip-shaped through hole and blocks the second light emitting section 610.

[0134] For example, the second cover plate may include, but is not limited to, an acrylic plate, a glass plate, etc.

[0135] For example, the second cover plate can be fixedly connected to the second fixed structure through processes such as bonding or welding.

[0136] For example, the second snap-fit ​​structure is disposed on the second fixed structure, and the second light emitting segment 610 is disposed on the second fixed structure through the second snap-fit ​​structure.

[0137] In other examples, the second part 220 is made of a light-transmitting material, and all of the second part 220 is a light-transmitting area.

[0138] In some examples, the first light emitting segment 510 and the second light emitting segment 610 are arranged opposite each other in the height direction of the housing 100, that is, the second direction is the width direction of the housing 100 and the third direction is the height direction of the housing 100.

[0139] In some examples where the first light-emitting section 510 and the second light-emitting section 610 are arranged opposite each other in the height direction of the housing 100, the second light-emitting section 610 extends from the third extension section 222 along the circumference of the housing 100 to the fourth extension section 223. That is, the two ends of the second light-emitting section 610 are located at the third light-emitting section and the fourth extension section 223, respectively. The second light-emitting section 610 is arranged at the third extension section 222, the second side section 221 and the fourth extension section 223. At this time, the third extension section 222 and the fourth extension section 223 are located on both sides of the mounting opening 410 in the width direction of the housing 100, and the second light-emitting section 610 extends from one side of the mounting opening 410 in the width direction of the housing 100 to the other side of the mounting opening 410 in the width direction of the housing 100.

[0140] Figure 12 is a schematic diagram of another type of seat belt buckle with a light guide fixing component at one end, provided in an embodiment of this application.

[0141] As shown in Figure 12, in some other examples where the first light emission section 510 and the second light emission section 610 are arranged opposite each other in the height direction of the housing 100, the second light emission section 610 is arranged in the second side section 221. In this case, the second light emission section 610 is located on one side of the mounting port 410 in the height direction of the housing 100.

[0142] In the example where the second part 220 includes the third extension 222 and the fourth extension 223, the second light emitting section 610 being located on the second side section 221 means that the second light emitting section does not extend to the third extension 222 and the fourth extension 223.

[0143] For example, the second ray emitting segment 610 can be a straight line segment or an arc segment.

[0144] Figure 13 is a schematic diagram of another type of seat belt buckle with a light guide fixing component at one end, provided in an embodiment of this application.

[0145] As shown in Figure 13, in some examples, the first light emitting segment 510 and the second light emitting segment 610 are arranged opposite to each other in the width direction of the housing 100. That is, the second direction is the height direction of the housing 100, and the third direction is the width direction of the housing 100.

[0146] In some examples where the first light-emitting section 510 and the second light-emitting section 610 are arranged opposite each other in the width direction of the housing 100, the second light-emitting section 610 extends from the third extension section 222 along the circumference of the housing 100 to the fourth extension section 223. That is, the two ends of the second light-emitting section 610 are located at the third extension section 222 and the fourth extension section 223, respectively. The second light-emitting section 610 is arranged at the third extension section 222, the second side section 221 and the fourth extension section 223. At this time, the third extension section 222 and the fourth extension section 223 are located on both sides of the mounting port 410 in the height direction of the housing 100, and the second light-emitting section 610 extends from one side of the mounting port 410 in the height direction of the housing 100 to the other side of the mounting port 410 in the height direction of the housing 100.

[0147] Figure 14 is a schematic diagram of another type of seat belt buckle with a light guide fixing component at one end, provided in an embodiment of this application.

[0148] As shown in Figure 14, in some examples where the first light emitting section 510 and the second light emitting section 610 are arranged opposite each other in the width direction of the housing 100, the second light emitting section 610 is arranged in the second side section 221. In this case, the second light emitting section 610 is located on one side of the mounting port 410 in the width direction of the housing 100.

[0149] Figure 15 is a schematic diagram of the cooperation between the first and second light guides of a seat belt buckle and the first light source provided in an embodiment of this application.

[0150] As shown in Figure 15, in some possible embodiments, one end of the second light guide section 620 is connected to one end of the second light emission section 610, and the other end of the second light guide section 620 faces the first light source 340. That is, the other end of the second light guide section 620 and the end of the first light guide section 520 away from the first light emission section 510 face the same light source. The first light source 340 injects light into the end of the second light guide section 620 away from the second light emission section 610. In other words, the first light guide 500 and the second light guide 600 can be arranged in parallel.

[0151] In this way, the first light source 340 can simultaneously emit light into the first light guide 500 and the second light guide 600, reducing the number of light sources required within the housing 100. Furthermore, fewer light sources are needed, which helps reduce energy consumption.

[0152] For example, one end of the second light-introducing section 620 away from the second light-emitting section 610 may be located inside the housing 100.

[0153] In some other possible implementations, the seatbelt buckle may also include a second light source (not shown), with the first light source 340 and the second light source being two different light sources. The end of the second light-guiding section 620 facing away from the second light-emitting section 610 faces the second light source; that is, the other end of the second light-guiding section 620 and the end of the first light-guiding section 520 facing away from the first light-emitting section 510 face different light sources, and the second light source directs light into the end of the second light-guiding section 620 facing away from the second light-emitting section 610.

[0154] This allows for independent control of the light emission from the first light guide 500 and the second light guide 600.

[0155] In some possible implementations, the seatbelt buckle further includes a detection device (not shown) disposed on the locking mechanism 330. The detection device is used to detect the engagement state of the locking mechanism 330. The engagement state includes a state in which the seatbelt insert is engaged and a state in which the seatbelt insert is not engaged.

[0156] This makes it easier to know the engagement / disengagement state of the locking mechanism 330, so as to enable relevant control based on the engagement / disengagement state of the locking mechanism 330.

[0157] In some examples, the detection device can be used to detect the impedance of the locking mechanism 330, and the engagement state of the locking mechanism 330 can be detected by the difference in impedance of the locking mechanism 330 in the state where the seat belt insert is engaged and in the state where the seat belt insert is not engaged.

[0158] In other examples, the detection device may also be a pressure sensor or a position sensor, etc.

[0159] In some possible implementations, the vehicle also includes a controller (not shown), a detection device electrically connected to the controller, a first light source 340 electrically connected to the controller, and the controller can control the first light source 340 according to the detection structure of the detection device.

[0160] In some examples, the seatbelt buckle may include a controller, which may be located within the housing 100.

[0161] In other examples, the seatbelt buckle does not include a controller; the controller and seatbelt buckle are two separate components. For example, the controller may be the central controller of the vehicle.

[0162] For example, the controller can be used to obtain the engagement state of the locking mechanism 330, wherein the engagement state of the locking mechanism 330 is detected by a detection device.

[0163] In some examples, the controller is also configured to issue a first command to instruct the first light source 340 to emit light when the locking mechanism 330 is in the state where the seat belt insert is not engaged. The controller is also configured to issue a second command to instruct the first light source 340 to stop emitting light when the locking mechanism 330 is in the state where the seat belt insert is engaged.

[0164] In some possible implementations, the first light source 340 is a light source with variable emission color.

[0165] In this way, by changing the color of the light emitted by the first light source 340, different information can be provided to the user, or different environmental effects can be created.

[0166] In some examples where the first light source 340 is a variable-color light source, the controller is also configured to issue a third command to instruct the first light source 340 to emit light of a first color when the locking mechanism 330 is in a state where the seatbelt insert is not engaged. The controller is also configured to issue a fourth command to instruct the first light source 340 to emit light of a second color when the locking mechanism 330 is in a state where the seatbelt insert is engaged. For example, the first color could be white, and the second color could be blue.

[0167] For example, the first light source 340 may include a first sub-light source (not shown) and a second sub-light source (not shown). The first sub-light source emits light of a first color, and the second sub-light source emits light of a second color. Both the first and second sub-light sources emit light toward the end of the first light-guiding section 520 that is away from the first light-emitting section 510. When the seatbelt buckle includes a second light guide 600, the first and second sub-light sources also emit light toward the end of the second light-guiding section 620 that is away from the second light-emitting section 610.

[0168] For example, both the first and second sub-light sources can be light-emitting diode (LED) light sources.

[0169] For example, both the first and second sub-light sources are electrically connected to the controller, the third instruction is used to instruct the first sub-light source to emit light, and the fourth instruction is used to instruct the second sub-light source to emit light.
