Description

安全带自锁锁舌Safety belt self-locking tongue 技术领域Technical field
本公开涉及汽车安全领域，更具体地说涉及一种安全带自锁锁舌。The present disclosure relates to the field of automobile safety, and more specifically to a safety belt self-locking bolt.
背景技术Background technique
目前在车辆中广泛使用三点式安全带，三点式安全带的织带上设有可滑动的锁舌。乘客在佩戴安全带时将锁舌***插锁，即可约束在车辆座椅上。锁舌将织带分为用于限制乘客上身前移的肩带段、以及用于限制乘客腰部前移的腰带段。At present, three-point safety belts are widely used in vehicles, and the webbing of the three-point safety belt is provided with a slidable bolt. When the passenger wears the seat belt, insert the bolt into the mortise lock to be restrained on the vehicle seat. The lock tongue divides the webbing into a shoulder belt section for restricting the forward movement of the passenger's upper body and a waist belt section for restricting the forward movement of the passenger's waist.
普通的安全带锁舌不具备锁定织带的能力，因此肩带段和腰带段的长度可随乘客身体的移动发生变化。在车辆正常情况下，织带可以从卷收器中自由地拉出和卷收进去，以将乘客固定在规定的位置上。在车辆发生碰撞等紧急情况时，卷收器由于惯性机构锁住织带的总长度，并且乘客的腰部会发生较大位移，织带的腰带段被拉长，从而导致肩带段缩短。肩带段的缩短会压迫乘客的胸部，从而对乘客的胸部造成伤害。Ordinary seat belt tongues do not have the ability to lock the webbing, so the length of the shoulder belt section and the waist belt section can change with the movement of the passenger's body. Under normal conditions of the vehicle, the webbing can be freely pulled out and rolled in from the retractor to fix the passengers in the specified position. In an emergency situation such as a vehicle collision, the retractor locks the total length of the webbing due to the inertial mechanism, and the passenger's waist will have a large displacement, and the waistband section of the webbing is stretched, resulting in the shortening of the shoulder belt section. The shortening of the shoulder straps will compress the passenger's chest, thereby causing injury to the passenger's chest.
目前已经开发出带有锁止功能的安全带锁舌，其通过在织带上施加锁止力来限制腰带段和肩带段之间的相互移动，从而降低对乘客胸部的伤害。该锁舌设有由转轴支撑的回转体，回转体可以从初始位置转动到锁定位置以锁定织带，并且可以通过复位件从锁定位置复位到初始位置。现有的安全带锁舌从回转体的正面将复位件装入回转体中并利用侧盖进行遮挡，或者将复位件嵌入锁舌主体的包塑部分中。At present, a seat belt tongue with a locking function has been developed, which restricts the mutual movement between the waist belt section and the shoulder belt section by applying a locking force on the webbing, thereby reducing the damage to the passenger's chest. The lock tongue is provided with a revolving body supported by a rotating shaft, and the revolving body can be rotated from an initial position to a locking position to lock the webbing, and can be reset from the locking position to the initial position by a resetting member. In the existing seat belt bolt, the reset piece is inserted into the revolving body from the front of the revolving body and the side cover is used for shielding, or the reset piece is embedded in the overmolded part of the bolt main body.
然而，利用转轴作为回转体的支撑或导向，这增加了锁舌的装配难度和结构复杂性。将复位件正面装入回转体需要额外的侧盖，并且当施加在织带上的负载过大时侧盖容易从回转体松脱；而将复位件嵌在包塑部分中增加了工艺难度，降低了零件的稳定性。However, the use of the rotating shaft as the support or guide of the revolving body increases the assembly difficulty and structural complexity of the bolt. Inserting the front of the resetting part into the revolving body requires an additional side cover, and when the load on the webbing is too large, the side cover is easy to loosen from the revolving body; and embedding the resetting part in the overmolding part increases the process difficulty and reduces Improve the stability of the parts.

图1和2分别示出根据本公开第一实施例的安全带自锁锁舌1的组装立体图和分解立体图。如图所示，安全带自锁锁舌1包括锁舌主体2、以及设置在锁舌主体2上的回转体3和复位件4。锁舌主体2以可滑动的方式连接至安全带织带5，并且能够可移除地***安全带插锁(未示出)中。回转体3可转动地支撑在锁舌主体2上，并且能够从初始位置转动到锁定位置以与锁舌主体2一起夹持和锁定安全带织带5。复位件4设置在回转体3内，并且用于将回转体3从锁定位置复位到初始位置。1 and 2 respectively show an assembled perspective view and an exploded perspective view of the safety belt self-locking bolt 1 according to the first embodiment of the present disclosure. As shown in the figure, the safety belt self-locking bolt 1 includes a bolt body 2, and a revolving body 3 and a reset member 4 arranged on the bolt body 2. The bolt body 2 is slidably connected to the seat belt webbing 5 and can be removably inserted into a seat belt mortise lock (not shown). The revolving body 3 is rotatably supported on the bolt main body 2 and can be rotated from the initial position to the locking position to clamp and lock the seat belt webbing 5 together with the bolt main body 2. The reset member 4 is provided in the revolving body 3, and is used to reset the revolving body 3 from the locked position to the initial position.
锁舌主体2包括下方的插锁部22和上方的织带部21。插锁部22连接至织带部21，并且两者可以是一体成型的。插锁部22从织带部21向下伸出，并且呈伸长状。插锁部22可以***安全带插锁中，从而安全带织带5能够将乘客约束在车辆座椅上。The bolt body 2 includes a lower mortise lock portion 22 and an upper webbing portion 21. The mortise lock part 22 is connected to the webbing part 21, and the two may be integrally formed. The latch portion 22 protrudes downward from the webbing portion 21 and is elongated. The mortise lock portion 22 can be inserted into the seat belt mortise lock, so that the seat belt webbing 5 can restrain the passenger on the vehicle seat.
织带部21呈大致矩形的板状，并且矩形的四个角部可以具有倒圆。织带部21沿竖直方向可以具有一定的弯曲弧度。本文将织带部21的外凸侧称为前侧，内凹侧称为后侧。织带部21的基板211上设有水平开口212，供安全带织带5穿过。水平开口212可以呈伸长形，并且大致位于基板211的中心。如图3和4所示，水平开口212包括上表面212T、下表面212B、以及连接上表面212T和下表面212B的两个侧表面。上表面212T呈外凸的弧形，用于接触回转体3并且引导回转体3在其上滑动。下表 面212B大致平坦，并且和回转体3彼此相对，从而在其间形成供安全带织带5穿过的织带通道212C。当回转体3处于初始位置(参见图3)时，下表面212B和回转体3间隔开一段距离，织带通道212C打开，安全带织带5可以穿过其中***。当回转体3从初始位置转动到锁定位置(参见图4)时，织带通道212C关闭，回转体3和下表面212B夹持住安全带织带5，从而将安全带织带5锁定就位。The webbing portion 21 has a substantially rectangular plate shape, and four corners of the rectangle may have rounds. The webbing portion 21 may have a certain curvature along the vertical direction. Herein, the convex side of the webbing portion 21 is referred to as the front side, and the concave side is referred to as the back side. The base plate 211 of the webbing portion 21 is provided with a horizontal opening 212 for the safety belt webbing 5 to pass through. The horizontal opening 212 may be elongated and located approximately at the center of the substrate 211. 3 and 4, the horizontal opening 212 includes an upper surface 212T, a lower surface 212B, and two side surfaces connecting the upper surface 212T and the lower surface 212B. The upper surface 212T has a convex arc shape for contacting the revolving body 3 and guiding the revolving body 3 to slide thereon. The lower surface 212B is substantially flat and faces the revolving body 3, thereby forming a webbing passage 212C through which the seat belt webbing 5 passes. When the revolving body 3 is in the initial position (see FIG. 3), the lower surface 212B and the revolving body 3 are separated by a certain distance, the webbing passage 212C is opened, and the seat belt webbing 5 can move freely through it. When the revolving body 3 rotates from the initial position to the locked position (see FIG. 4), the webbing channel 212C is closed, and the revolving body 3 and the lower surface 212B clamp the seat belt webbing 5, thereby locking the seat belt webbing 5 in place.
返回图2，织带部21在水平开口212的左右两侧设有左右支撑部213，以将回转体3可转动地支撑在锁舌主体2上。每个支撑部213包括垂直于基板211向后伸出的支撑部主体214。支撑部主体214的外侧表面可以设置成与基板211的侧表面齐平，或者向内与基板211的侧表面间隔开。支撑部主体214的内侧表面设有沿水平方向向内伸出的弧形凸起215。回转体3可以支撑在弧形凸起215上并且绕弧形凸起215转动。支撑部主体214的内侧表面可以防止回转体3沿水平方向发生移位。每个支撑部213还设有供复位件4穿过的水平通孔216。另外，参见图5，左支撑部213的水平通孔216的外侧部分设有限位槽217，以控制复位件4的装配角度和防止复位件4过装配而完全伸入右支撑部213的水平通孔216中。Returning to FIG. 2, the webbing portion 21 is provided with left and right support portions 213 on the left and right sides of the horizontal opening 212 to rotatably support the revolving body 3 on the bolt main body 2. Each supporting portion 213 includes a supporting portion main body 214 extending backward perpendicular to the base plate 211. The outer side surface of the support body 214 may be arranged to be flush with the side surface of the substrate 211 or spaced inwardly from the side surface of the substrate 211. The inner surface of the support body 214 is provided with an arc-shaped protrusion 215 extending inward in the horizontal direction. The revolving body 3 can be supported on the arc-shaped protrusion 215 and rotate around the arc-shaped protrusion 215. The inner surface of the support main body 214 can prevent the revolving body 3 from shifting in the horizontal direction. Each supporting portion 213 is also provided with a horizontal through hole 216 for the resetting member 4 to pass through. In addition, referring to FIG. 5, the outer part of the horizontal through hole 216 of the left support portion 213 is provided with a limiting groove 217 to control the assembly angle of the resetting piece 4 and prevent the resetting piece 4 from being over-assembled to completely extend into the horizontal through hole of the right support portion 213.孔216中.
回转体3与锁舌主体2配合，用于在车辆发生紧急情况时夹持和锁定安全带织带5。如图2所示，回转体3呈大致C形，并且包括上曲面3T、下曲面3B、前表面3F、后表面3R、以及连接上述四个表面的两个侧表面3S。下曲面3B搁置在左右支撑部213的弧形凸起215上。下曲面3B和弧形凸起215的上表面贴合，从而下曲面3B能够绕弧形凸起215在初始位置和锁定位置之间转动。上曲面3T和锁舌主体2的水平开口212的上表面212T相贴合、或者具有相同的曲率半径，从而当下曲面3B绕弧形凸起215在初始位置和锁定位置之间转动时，上曲面3T能够沿着水平开口212的上表面212T滑动。也就是说，回转体3在锁舌主体2的水平开口212的上表面212T和弧形凸起215的上表面形成的通道内转动，从而回转体3可以省略掉起支撑作用的转轴，减轻了零件重量。The revolving body 3 cooperates with the bolt main body 2 for clamping and locking the seat belt webbing 5 when the vehicle is in an emergency. As shown in FIG. 2, the revolving body 3 is substantially C-shaped, and includes an upper curved surface 3T, a lower curved surface 3B, a front surface 3F, a rear surface 3R, and two side surfaces 3S connecting the above four surfaces. The lower curved surface 3B rests on the arc-shaped protrusions 215 of the left and right supporting parts 213. The lower curved surface 3B is attached to the upper surface of the arc-shaped protrusion 215, so that the lower curved surface 3B can rotate around the arc-shaped protrusion 215 between the initial position and the locked position. The upper curved surface 3T and the upper surface 212T of the horizontal opening 212 of the bolt body 2 fit or have the same radius of curvature, so that when the lower curved surface 3B rotates around the arc-shaped protrusion 215 between the initial position and the locked position, the upper curved surface The 3T can slide along the upper surface 212T of the horizontal opening 212. In other words, the revolving body 3 rotates in the channel formed by the upper surface 212T of the horizontal opening 212 of the bolt body 2 and the upper surface of the arc-shaped protrusion 215, so that the revolving body 3 can omit the supporting shaft, which reduces Part weight.
后表面3R抵靠在安全带织带5上，从而在车辆发生紧急情况时安全带织带5的运动能够带动回转体3从初始位置转动到锁定位置。在回转体3处于锁定位置时，前表面3F能够与锁舌主体2的水平开口212的下表面212B一起夹持和锁定安全带织带5，如图4所示。在一些实施例中，回转体3的前表面3F和/或水平开口212的下表面212B具有一个或多个齿，起到增大摩擦力的作用，从而在夹持和锁定安全带织带5时不发生滑移。The rear surface 3R abuts on the seat belt webbing 5, so that the movement of the seat belt webbing 5 can drive the revolving body 3 to rotate from the initial position to the locked position when the vehicle is in an emergency. When the revolving body 3 is in the locked position, the front surface 3F can clamp and lock the seat belt webbing 5 together with the lower surface 212B of the horizontal opening 212 of the bolt main body 2, as shown in FIG. 4. In some embodiments, the front surface 3F of the revolving body 3 and/or the lower surface 212B of the horizontal opening 212 have one or more teeth, which play a role in increasing friction, so that when clamping and locking the seat belt webbing 5 No slippage occurs.
回转体3还包括贯穿其两个侧表面3S的通孔31，用于容纳复位件4。通孔31仅在两个侧表面3S上开口，并且不在回转体3的其他表面上开口露出。在沿前后方向的横截面中，通孔31的外轮廓的曲率与回转体3的上曲面3T大致相同，从而复位件4和回转体3的运动轨迹保持一致，有利于复位件4顺利回到初始位置。通孔31可以位于回转体3的后侧部分。在一些实施例中，通孔31大致呈腰形。The revolving body 3 also includes a through hole 31 penetrating through its two side surfaces 3S for accommodating the reset member 4. The through hole 31 only opens on the two side surfaces 3S, and does not open and expose on the other surfaces of the revolving body 3. In the cross-section along the front-rear direction, the curvature of the outer contour of the through hole 31 is approximately the same as the upper curved surface 3T of the revolving body 3, so that the movement trajectories of the resetting member 4 and the revolving body 3 are kept consistent, which is conducive to the smooth return of the resetting member 4 initial position. The through hole 31 may be located at the rear part of the revolving body 3. In some embodiments, the through hole 31 is generally waist-shaped.
复位件4用于将回转体3保持在锁舌主体2上并偏压至初始位置，并且在回转体3处于锁定位置时将回转体3从锁定位置复位到初始位置。如图2所示，复位件4呈大致线状。复位件4在其中心处具有一个或多个波状部41，所述波状部41的高度大于回转体3的通孔31的高度，从而复位件4能够以预压缩的方式装配在通孔31内。复位件4的右端部呈直线形，用于***右支撑部213的水平通孔216内。复位件4的左端部***左支撑部213的水平通孔216内，并且末端具有呈大致钩状的限位部42，用于与左支撑部213的限位槽217配合，以控制复位件4的装配角度和防止复位件4过装配而完全伸入右支撑部213的水平通孔216中。The reset member 4 is used to hold the revolving body 3 on the bolt main body 2 and bias it to the initial position, and to reset the revolving body 3 from the locked position to the initial position when the revolving body 3 is in the locked position. As shown in Fig. 2, the restoring member 4 is substantially linear. The restoring member 4 has one or more wavy portions 41 at its center, and the height of the wavy portions 41 is greater than the height of the through hole 31 of the revolving body 3, so that the restoring member 4 can be assembled in the through hole 31 in a pre-compressed manner . The right end of the restoring member 4 is linear, and is used to be inserted into the horizontal through hole 216 of the right supporting portion 213. The left end of the restoring member 4 is inserted into the horizontal through hole 216 of the left supporting portion 213, and the end has a substantially hook-shaped limiting portion 42 for mating with the limiting groove 217 of the left supporting portion 213 to control the resetting member 4 The assembly angle of the assembly and prevents the reset member 4 from being over-assembled and completely extending into the horizontal through hole 216 of the right supporting portion 213.
限位部42和波状部41成一定的角度，并且左支撑部213中的限位槽217与水平通孔216成相同的角度。左支撑部213的水平通孔216与回转体3的通孔31形状一致，从而便于复位件4的波状部41顺利装入穿过两个通孔，进而控制复位件4装入后的角度。限位槽217与复位件4的限位部42的终止面相接触，以防止复位件4过装配而完全伸入右支撑部213的水平通孔216中。The limiting portion 42 and the wavy portion 41 form a certain angle, and the limiting groove 217 in the left support portion 213 and the horizontal through hole 216 form the same angle. The horizontal through hole 216 of the left supporting portion 213 has the same shape as the through hole 31 of the revolving body 3, so that the wave-shaped portion 41 of the resetting member 4 can be smoothly inserted through the two through holes, thereby controlling the angle of the resetting member 4 after being installed. The limiting groove 217 is in contact with the end surface of the limiting portion 42 of the resetting member 4 to prevent the resetting member 4 from being over-assembled and completely extending into the horizontal through hole 216 of the right supporting portion 213.
如图6所示，复位件4依次穿过锁舌主体2的左支撑部213的水平通孔216、回转体3的通孔31、和锁舌主体2的右支撑部213的水平通孔216，从而将回转体3装配在锁舌主体2上并保持在初始位置。右支撑部213的水平通孔216不仅可以支撑复位件4，并且便于拆卸工具***其内以拆卸复位件4。As shown in FIG. 6, the restoring member 4 passes through the horizontal through hole 216 of the left support portion 213 of the bolt body 2, the through hole 31 of the revolving body 3, and the horizontal through hole 216 of the right support portion 213 of the bolt body 2 in sequence. , Thereby assembling the revolving body 3 on the bolt body 2 and keeping it in the initial position.

下面接合图3和4说明根据本公开第一实施例的安全带自锁锁舌1的工作原理。当车辆发生碰撞等紧急情况时，安全带织带5上承受的负载超过规定负载，安全带织带5有从其肩带段52穿过织带通道212C朝向腰带段51移动的倾向。安全带织带5的腰带段51与回转体3的后表面3R紧密贴合并产生滑动摩擦，从而推动回转体3抵抗复位件4的复位力，绕锁舌主体2的弧形凸起215从初始位置逆时针(参见箭头A)转动到锁定位置。The working principle of the safety belt self-locking tongue 1 according to the first embodiment of the present disclosure will be described below with reference to FIGS. 3 and 4. When an emergency situation such as a vehicle collision occurs, the load on the seat belt webbing 5 exceeds a prescribed load, and the seat belt webbing 5 tends to move from its shoulder belt section 52 through the webbing channel 212C toward the waist belt section 51. The waistband section 51 of the seat belt webbing 5 closely adheres to the rear surface 3R of the revolving body 3 and generates sliding friction, thereby pushing the revolving body 3 to resist the resetting force of the resetting member 4, and surround the arc-shaped protrusion 215 of the bolt body 2 from the initial position Turn counterclockwise (see arrow A) to the locked position.
在锁定位置，织带通道212C关闭，并且回转体3的前表面3F将安全带织带5挤压到水平开口212的下表面212B上直至变形，从而夹持和锁定安全带织带5。由此， 安全带织带5的腰带段51和肩带段52无法相互移动，从而减小乘客腰部位移，降低对乘客胸部造成伤害。此时，复位件4处于弹性变形状态。In the locked position, the webbing channel 212C is closed, and the front surface 3F of the revolving body 3 squeezes the webbing webbing 5 onto the lower surface 212B of the horizontal opening 212 until it is deformed, thereby clamping and locking the webbing webbing 5. Therefore, the waist belt section 51 and the shoulder belt section 52 of the seat belt webbing 5 cannot move mutually, thereby reducing the displacement of the passenger's waist and reducing the damage to the passenger's chest. At this time, the restoring member 4 is in an elastically deformed state.
当施加在安全带织带5上的负载解除时，安全带织带5的腰带段51与回转体3的后表面3R松开接触，并且复位件4的回复力使回转体3从锁定位置回到初始位置。由此回转体3的前表面3F移动远离水平开口212的下表面212B，并且织带通道212C打开。安全带织带5可以穿过织带通道212C自由移动。When the load applied to the seat belt webbing 5 is released, the waist belt section 51 of the seat belt webbing 5 releases contact with the rear surface 3R of the revolving body 3, and the restoring force of the reset member 4 causes the revolving body 3 to return to the initial position from the locked position position. Thereby, the front surface 3F of the revolving body 3 moves away from the lower surface 212B of the horizontal opening 212, and the webbing passage 212C is opened. The seat belt webbing 5 can move freely through the webbing channel 212C.
