Description
本发明涉及一种婴儿推车,特别是童车的轮子的锁定机构。The invention relates to a baby stroller, in particular to a locking mechanism for a wheel of a stroller.
现有技术中,童车车轮的锁定机构,包括车轮、与车轮的中央相转动连接的车轮轴、设置于车轮上的多个呈圆周分布的锁定槽,在车轮的一侧设有与车架相连接的刹车踏脚,向下踏动刹车踏脚时,连接于刹车踏脚上的刹车块插入锁定槽内,使车轮不能转动。当需要解锁时,需要用脚背向上钩起刹车踏脚,使刹车块脱离锁定槽,这种锁定机构操作时有向上和向下两种动作,用脚操作不便,易损伤、弄脏鞋面,特别是在穿有脚背暴露的鞋时更容易损伤脚背面。In the prior art, the locking mechanism of the stroller wheel includes the wheel, the wheel shaft that is rotatably connected to the center of the wheel, and a plurality of circumferentially distributed locking grooves arranged on the wheel. The connected brake pedal, when the brake pedal is stepped downward, the brake block connected to the brake pedal is inserted into the locking groove, so that the wheel cannot rotate. When it needs to be unlocked, it is necessary to hook up the brake pedal with the instep to make the brake block break away from the locking groove. This locking mechanism has two movements, upward and downward. Especially when wearing shoes with exposed instep, it is easier to damage the back of the foot.
本发明的目的在于提供一种向下踩动踏脚时可完成刹车锁定或解锁动作的童车车轮的锁定机构。The object of the present invention is to provide a wheel locking mechanism of a stroller that can complete brake locking or unlocking when the pedal is stepped down.
本发明的技术方案是:一种童车车轮的锁定机构,包括车轮、与车轮的中央相转动连接的车轮轴、设置于车轮上的多个呈圆周分布的锁定槽;所述的车轮的侧部设有可绕车轮轴转动的棘轮,所述的棘轮外套有可绕棘轮转动的踏把套,所述的踏把套上设有棘爪,所述的棘爪与所述的棘轮外圆周上的棘齿相啮合,所述的踏把套上连接有径向延伸的刹车踏把,所述的踏把套上连接有复位弹簧;所述的棘轮的内腔中设有可轴向移动的滑块,该滑块的朝向车轮的一侧固定有至少一根轴向的锁定销,该锁定销穿过与车腿相连接的车腿外罩的锁定销孔,并在锁定状态下插在所述的锁定槽内,所述的滑块的侧部设有使锁定销趋于向车轮的方向移动的压簧;所述的棘轮的内腔壁设有至少一个径向凸起的凸块,所述的滑块的外表面设有一侧壁轴向笔直的导向槽,所述的导向槽的另一侧壁设有导向斜面,在锁定状态下所述的凸块插在所述的导向槽内。踏下刹车踏把后,踏把套作顺时针转动,则踏把套上的棘爪推动棘轮也作顺时针转动,当棘轮上的凸块转至滑块上的导向槽内时,滑块在压簧的推动作用下向车轮方向滑动,使锁定销插进车轮的锁定槽内,刹住车轮,而刹车踏把在复位弹簧的作用下逆时针复位,完成锁定状态。再踏刹车踏把时,踏把套再作顺时针转动,则踏把套上的棘爪推动棘轮也再作顺时针转动,棘轮上的凸块在导向槽内沿导向斜面克服压簧的压力也作顺时针滑动,使滑块向远离车轮方向后退,带动锁定销腿出锁定槽,释放车轮,完成解锁状态,而凸块在滑块的靠近车轮的滑块端面被挡住。刹车踏把在复位弹簧的作用下复位,如此周而复始,可实现锁定车轮的状态和解锁状态。The technical solution of the present invention is: a locking mechanism for baby carriage wheels, including wheels, wheel shafts that are rotatably connected to the center of the wheels, and a plurality of circumferentially distributed locking grooves arranged on the wheels; the side parts of the wheels A ratchet wheel that can rotate around the wheel shaft is provided. The ratchet wheel is covered with a handle cover that can rotate around the ratchet wheel. The ratchet teeth are engaged, the brake pedal is connected to the radially extending brake pedal, and the return spring is connected to the pedal sleeve; the inner chamber of the ratchet wheel is provided with a movable Slide block, one side of the slide block facing the wheel is fixed with at least one axial locking pin, the locking pin passes through the locking pin hole of the leg cover connected with the car leg, and is inserted in the locked state In the above-mentioned locking groove, the side of the slider is provided with a compression spring that makes the locking pin tend to move toward the wheel; the inner cavity wall of the ratchet is provided with at least one radially protruding bump, The outer surface of the slider is provided with a guide groove with one side wall axially straight, and the other side wall of the guide groove is provided with a guide slope, and the protrusion is inserted into the guide groove in the locked state. Inside. After stepping on the brake pedal, the pedal cover rotates clockwise, and the pawl on the pedal cover pushes the ratchet to also rotate clockwise. When the bump on the ratchet turns into the guide groove on the slider, the slider Under the pushing action of the compression spring, it slides towards the wheel direction, so that the locking pin is inserted into the locking groove of the wheel, and the wheel is braked, and the brake pedal resets counterclockwise under the action of the return spring to complete the locked state. When stepping on the brake pedal again, the pedal cover will rotate clockwise again, and then the pawl on the pedal cover will push the ratchet to rotate clockwise again, and the bump on the ratchet will overcome the pressure of the compression spring along the guide slope in the guide groove. Also slide clockwise to make the slide block retreat away from the wheel direction, drive the locking pin legs out of the locking groove, release the wheel, and complete the unlocked state, while the projection is blocked on the end face of the slide block near the wheel. The brake pedal is reset under the action of the return spring, so that it goes round and round to realize the locked state and the unlocked state of the wheel.
本发明与现有技术相比具有下列优点:Compared with the prior art, the present invention has the following advantages:
刹车和释放状态都是下踏的动作,便于鞋底的下踏操作,动作方式简单,容易操作。Both the brake and release states are depressing actions, which are convenient for the depressing operation of the sole, and the action mode is simple and easy to operate.

实施例:参见附图1、附图2、附图3,一种童车车轮的锁定机构,包括车轮[3]、与车轮[3]的中央相转动连接的车轮轴[7]、设置于车轮[3]上的多个呈圆周分布的锁定槽[2]。所述的车轮[3]的侧部设有可绕车轮轴[7]转动的棘轮[6],所述的棘轮[6]外套有可绕棘轮[6]转动的踏把套[12],所述的踏把套[12]上设有棘爪[18],所述的棘爪[18]通过棘爪轴[19]铰接于踏把套[12]上,所述的棘爪[18]与套在棘爪轴[19]上的扭簧[20]相连接。所述的棘爪[18]与所述的棘轮[6]外圆周上的棘齿[21]相啮合,所述的踏把套[12]上连接有径向延伸的刹车踏把[5],所述的踏把套[12]上连接有复位弹簧,所述的踏把套[12]所连接的复位弹簧是套在车轮轴[7]上的扭簧[9],也可以用偏心的拉簧。所述的棘轮[6]的内腔中设有可轴向移动的滑块[14],该滑块[14]的朝向车轮[3]的一侧固定有至少一根轴向的锁定销[10],附图2中的锁定销[10]为对称设置的两个。该锁定销[10]穿过与车腿[4]相连接的车腿外罩[8]的锁定销孔,也可以穿过与车架相连接的其它部件的锁定销孔,还可以在滑块[14]圆周方向不能转动的情况下,锁定销[10]不再穿过固定部件的锁定销孔。在锁定状态下锁定销[10]插在所述的锁定槽[2]内。由于车腿外罩[8]与车腿[4]相固定连接,故锁定销[10]穿过车腿外罩[8]上的锁定销孔后锁定销[10]为锁定状态,因此锁定销[10]可以锁定车轮[3]。所述的滑块[14]的右侧部设有使锁定销[10]趋于向车轮[3]的方向移动(即向左方向)的压簧[15],也可在滑块的左侧部使用等效替换的拉簧的结构;所述的棘轮[6]的内腔壁设有至少一个径向凸起的凸块[13],附图3中的凸块[13]设有呈120度分布的三个,所述的轴向导向槽[16]也设有与凸块[13]相配合的三个,这样的三个凸块[13]可使滑块[14]均匀受力,轴向滑动时平稳。滑块的结构可参见附图4、附图5、附图6,所述的滑块[14]的外表面设有一侧壁轴向笔直的导向槽[16](所述的导向槽[16]与车轮轴有很小的夹角也是许可的,因为棘轮[6]可以作相应的转动),所述的导向槽[16]的另一侧壁设有导向斜面[11],所述的导向斜面[11]是偏离轴向的斜面,在凸块[13]位于导向槽[16]内并随棘轮[6]顺时针转动时,所述凸块[13]沿所述的导向斜面[11]滑动,压迫滑块[14]轴向向右滑动。如果在棘轮[6]的内壁设有导向槽,在滑块[14]的外表面设有凸块使两者相配合也可以,其结构正好是上述结构的相反构造,是一种等效替换。除附图6所示的导向槽结构外,导向槽还可以是所述的导向斜面[11]为螺旋槽的侧壁,或者所述的一个导向槽[16]包括一条轴向的直槽和一条螺旋槽,所述的直槽和螺旋槽相交,相交处位于滑块[14]的表面右侧。在锁定状态下所述的凸块[13]插在所述的导向槽[16]内。参见附图3,所述的滑块[14]的靠近车轮[3]一侧的外表面上设有锁定销定位槽[17],在解锁状态下,所述的凸块[13]插在所述的锁定销定位槽[17]内,所述的锁定销定位槽[17]的侧壁也设有导向斜面[23]。参见附图6,所述的导向斜面[23]是偏离轴向的斜面,在凸块[13]位于锁定销定位槽[17]内并随棘轮[6]转动时,所述的凸块[13]沿所述的导向斜面[23]滑动,压迫滑块[14]轴向滑动,使得凸块[13]能脱离锁定销定位槽[17]进入导向槽[16]内。参见附图7,所述的踏把套[12]上设有刹车踏把[5]的转动位置限位机构,使得每次踏下刹车踏把[5]一定角度后,限制刹车踏把[5]的转动,确保每次下踏的锁定和释放的成功,附图7是其中的一种限位机构的实施例,所述的转动位置限位机构是踏把套[12]上开有圆弧形的限位孔[24],所述的锁定销[10]穿过所述的限位孔[24],当锁定销[10]碰到限位孔[24]的端壁时,刹车踏把便不能再转动。此外,还可以把锁定销[10]的锁定方向由轴向改为径向。Embodiment: Referring to accompanying
