Definitions

  • This application relates to the field of seat belt technology, and in particular to a seat belt buckle, seat, and vehicle.
  • 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.
  • a seatbelt buckle that includes a housing and a light guide.
  • the light guide has a light-emitting section that surrounds the housing circumferentially.
  • the light-emitting section is prone to uneven brightness at different locations.
  • 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.
  • 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.
  • 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.
  • 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 its likelihood of breakage, minimizing light leakage due to breakage and further enhancing the uniformity of light emission.
  • 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.
  • 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.
  • 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.
  • the first part can protect the first light-emitting segment, making it less susceptible to damage from impacts.
  • 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.
  • the first portion has a socket that communicates with the inner cavity of the housing.
  • a first light-emitting segment is positioned near the socket, facilitating the emission of light by indicating the location of the socket.
  • the second part has a socket plate that connects to the inner cavity of the housing.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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
  • 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.
  • 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.

本申请实施例的提供的安全带锁扣，第一部分沿壳体的周向的尺寸较小，可使设置在第一部分的第一光线射出段的长度较短、使得光线在第一光线射出段内传播时的损耗较小，利于提高第一光线射出段发光的均匀性。此外，第一部分的拐角较少，可使设置在第一部分的第一光线射出段的拐角较少，利于减小光线在第一光线射出段内传播时的损耗，利于提高第一光线射出段发光的均匀性。另外，第一光线射出段的拐角较少也可使第一光线射出段不易发生断裂，第一光线射出段不易出现因发生断裂而漏光，利于提高第一光线射出段发光的均匀性。
在一种可能的实施方式中，第一光线射出段的拐角的数量小于或者等于2个。如此，光线在第一光线射出段内传播的损耗较小，此外，第一光线射出段发生断裂的风险也较小。
在一种可能的实施方式中，第一部分包括两端沿第二方向延伸的侧边段，侧边段位于安装口在第三方向上的一侧，第一光线射出段设置在侧边段。其中，第二方向和第三方向中的其中一个为壳体的宽度方向，第二方向和第三方向中的另一个为壳体的高度方向，第三方向与第二方向垂直，第三方向与第一方向垂直。如此，可使第一光线射出段的长度较短、拐角较少，利于提高第一光线射出段发光的均匀性。
在一种可能的实施方式中，第一部分的至少部分为透光区域，第一光线射出段设置在透光区域，第一光线射出段设于第一部分朝向壳体的内腔的一侧。如此，第一部分可以对第一光线射出段起到保护的作用，使得第一光线射出段不易因遭受碰撞而发生损坏。
在一种可能的实施方式中，第一部分朝向壳体的内腔的一侧具有卡接结构，第一光线射出段卡设在卡接结构内。如此，第一光线射出段与第一部分的连接较为方便。
在一种可能的实施方式中，第一部分具有连通壳体的内腔的插板插口。如此，第一光线射出段靠近插板插口，利于发光的第一光线射出段指示插板插口的位置。
在一种可能的实施方式中，第二部分具有连通壳体的内腔的插板插口。如此，第一光线射出段的布置不受插板插口的限制，可使第一光线射出段布置较为灵活。
在一种可能的实施方式中，第一部分和第二部分为分体结构。第一部分和第二部分分别与壳体固定连接。如此，光导在装配到光导固定件上时，需要弯折的程度较小，光导在装配到光导固定件的过程中不易发生折断。
在一种可能的实施方式中，该安全带锁扣还包括第二光导。第二光导包括第二光线射出段和第二光线导入段，第二光线射出段与第二光线导入段相连，第二光线射出段设置在第二部分。如此，可使光导固定件上的发光区域较大，便于将插板插口周围照亮。此外，第一光线射出段和第二光线射出段的长度均较短、且拐角均较少，第一光线射出段和第二光线射出段发光均较为均匀。
在一种可能的实施方式中，第二光线导入段的一端与第二光线射出段的一端相连，第二光线导入段的另一端和第一光线导入段背离第一光线射出段的一端朝向同一个光源，光源向第一光线导入段背离第一光线射出段的一端和第二光线导入段背离第二光线射出段的一端射入光线。
在一种可能的实施方式中，插接端设置有第一挡光部和第二挡光部，第一挡光部和第二挡光部分别设于插接端在第二方向上的两侧。第一部分位于第一挡光部和第二挡光部在第三方向上的一侧，第二部分位于第一挡光部和第二挡光部在第三方向上的另一侧，第一部分、第一挡光部、第二部分和第二挡光部围设形成安装口。如此，第一挡光部和第二挡光部可以对第一光线射出段和第二光线射出段发出的光线进行阻挡，以形成两个不发光的位置，以便于对插板插口进行定位。
在一种可能的实施方式中，壳体包括第一盖壳和第二盖壳。第一盖壳盖接在第二盖壳在第三方向上的一侧，第一挡光部和第二挡光部与第一盖壳固定连接，第一盖壳和第二盖壳中的其中一个与第一部分固定连接，第一盖壳和第二盖壳中的另一个与第二部分固定连接。如此，第一挡光部、第二挡光部、第一部分和第二部分装配较为方便。
在一种可能的实施方式中，该安全带锁扣还包括按键和锁紧机构，锁紧机构设置在壳体内，按键设置在安装口内，使得光导固定件和用于触发锁紧机构的按键安装较为容易。锁紧机构用于与安全带插板卡合，以便于实现安全带插板与安全带锁扣的卡合连接，使得安全带带体可以约束椅体上乘坐的驾乘人员。受按压到预设位置的按键用于使卡合的安全带插板与锁紧机构解除卡合，以便于使安全带插板与安全带锁扣解除连接，以解除安全带带体对椅体上乘坐的驾乘人员的约束。
在一种可能的实施方式中，该安全带锁扣还包括检测装置，检测装置设置在锁紧机构上，检测装置用于检测锁紧机构的卡合状态。其中，卡合状态包括卡合有安全带插板的状态和未卡合有安全带插板的状态。如此，便于掌握锁紧机构的卡合状态，以便于实现根据锁紧机构的卡合状态来进行相关控制。

然而，在相关技术中，光线射出段的长度较长、拐角较多，光线在光线射出段传播时的损耗较大，且光线射出段发生断裂的风险较大，使得光线射出段易出现不同位置的亮度不均匀的问题。
图3为本申请实施例提供的一种安全带锁扣的第一光导的示意图，图4为本申请实施例提供的一种安全带锁扣设置光导固定件一端的示意图。
如图3、图4所示，并参看图1、图2，基于此，在本申请实施例中，安全带锁扣还包括光导固定件200、第一光导500和第一光源340，第一光源340设置在壳体100内，光导固定件200设置在插接端，光导固定件200与壳体100固定连接。

在一些示例中，插板插口420与安装口410连通。如此，可使安全带锁扣的部件布置较为紧凑，利于减小安全带锁扣的尺寸。
在一些可能的实施方式中，第一光线射出段510的拐角的数量小于或者等于2个。
这样，光线在第一光线射出段510内传播的损耗较小，此外，第一光线射出段510发生断裂的风险也较小。

在另一些可能的实施方式中，安全带锁扣还可以包括第二光源(未示出)，第一光源340和第二光源为两个不同的光源。第二光线导入段620背离第二光线射出段610的一端朝向第二光源，也就是说，第二光线导入段620的另一端和第一光线导入段520背离第一光线射出段510的一端朝向不同的光源，第二光源向第二光线导入段620背离第二光线射出段610的一端射入光线。
这样，便于对第一光导500和第二光导600发光进行独立控制。
在一些可能的实施方式中，安全带锁扣还包括检测装置(未示出)，检测装置设置在锁紧机构330上，检测装置用于检测锁紧机构330的卡合状态。其中，卡合状态包括卡合有安全带插板的状态和未卡合有安全带插板的状态。
这样，便于掌握锁紧机构330的卡合状态，以便于实现根据锁紧机构330的卡合状态来进行相关控制。
在一些示例中，检测装置可以用于检测锁紧机构330的阻抗，通过锁紧机构330在卡合有安全带插板的状态和未卡合有安全带插板的状态的阻抗的不同来检测锁紧机构330的卡合状态。
在另一些示例中，检测装置也可以为压力传感器或者位置传感器等。
在一些可能的实施方式中，交通工具还包括控制器(未示出)，检测装置与控制器电连接，第一光源340与控制器电连接，控制器可以根据检测装置的检测结构来控制第一光源340。
在一些示例中，安全带锁扣可以包括控制器，控制器可以设置在壳体100内。
在另一些示例中，安全带锁扣不包括控制器，控制器与安全带锁扣为两个相互独立的部件，例如，控制器可以为交通工具的中央控制器。
示例性的，控制器可以用于获取锁紧机构330的卡合状态，其中，锁紧机构330的卡合状态由检测装置检测得到。
在一些示例中，控制器还用于在锁紧机构330处于未卡合有安全带插板的状态时，发出用于指示第一光源340发光的第一指令。控制器还用于在锁紧机构330处于卡合有安全带插板的状态时，发出用于指示第一光源340停止发光的第二指令。
在一些可能的实施方式中，第一光源340为发光颜色可变的光源。
这样，可以通过改变第一光源340发光的颜色，来为用户提供不同的信息，或者产生不同的环境效果。
在第一光源340为发光颜色可变的光源的一些示例中，控制器还用于在锁紧机构330处于未卡合有安全带插板的状态时，发出用于指示第一光源340发射第一颜色的光线的第三指令。控制器还用于在锁紧机构330处于卡合有安全带插板的状态时，发出用于指示第一光源340发射第二颜色的光线的第四指令。例如，第一颜色可以为白色，第二颜色可以为蓝色。
示例性的，第一光源340可以包括第一子光源(未示出)和第二子光源(未示出)，第一子光源用于发射第一颜色的光线，第二子光源用于发射第二颜色的光线，第一子光源和第二子光源朝向第一光线导入段520背离第一光线射出段510的一端发光。在安全带锁扣包括第二光导600时，第一子光源和第二子光源还朝向第二光线导入段620背离第二光线射出段610的一端发光。
示例性的，第一子光源和第二子光源均可以为发光二极管光源。
示例性的，第一子光源和第二子光源均与控制器电连接，第三指令用于指示第一子光源发光，第四指令用于指示第二子光源发光。
