除非另有定义,本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的,不是旨在限制本发明。Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention.

参阅图1,本发明公开了一种阻尼减震一体化的独轮车,包括:电机轮1、车架2和单筒阻尼减震器3。其中,车架2相对电机轮1上下活动连接,车架2的两侧分别设置有脚踏板21;单筒阻尼减震器3连接于电机轮1和车架2之间,为车架2的上下活动提供减震和阻尼。Referring to FIG. 1 , the present invention discloses a unicycle with integrated damping and shock absorption, including: a motor wheel 1 , avehicle frame 2 and a monotube damping shock absorber 3 . Wherein, thevehicle frame 2 is movable up and down relative to the motor wheel 1, andpedals 21 are respectively arranged on both sides of thevehicle frame 2; The up and down movement provides shock absorption and damping.

结合图2和图3,重要的,单筒阻尼减震器3包括缸筒31、活塞杆32、油活塞33以及浮游塞34,油活塞33和浮游塞34依次滑动设置于缸筒31的内部,以将缸筒31内部的空腔依次分隔为第一油腔311、第二油腔312和气腔313,活塞杆32由缸筒31的一端穿入第一油腔311并与油活塞33相连接,活塞杆32和/或油活塞33上设置有用于导通第一油腔311和第二油腔312的阻尼阀35。Referring to Fig. 2 and Fig. 3, it is important that the monotubedamping shock absorber 3 includes acylinder 31, apiston rod 32, anoil piston 33 and afloating plug 34, and theoil piston 33 and thefloating plug 34 are slidably arranged inside thecylinder 31 in sequence , so as to divide the cavity inside thecylinder 31 into afirst oil chamber 311, asecond oil chamber 312 and anair chamber 313, and thepiston rod 32 penetrates into thefirst oil chamber 311 from one end of thecylinder 31 and is in contact with theoil piston 33. connection, thepiston rod 32 and/or theoil piston 33 are provided with adamping valve 35 for conducting thefirst oil chamber 311 and thesecond oil chamber 312 .

以图3所示的方向为参考,在上述的单筒阻尼减震器3中,气体封存于气腔313,液体(液压油)封存于第一油腔311和第二油腔312,并具体通过阻尼阀35在第一油腔311和第二油腔312之间流动,由于活塞杆32位于第一油腔311以占用一定的空间,这将导致第一油腔311的容油横截面小于第二油腔312的容油横截面。在不骑行的情况下,气腔313内的气压作用于浮游塞34,浮游塞34向上滑动以压缩液体,由于浮游塞34的压缩作用以及两油腔311、312的容油横截面的差异,第一油腔311内的液体将通过阻尼阀35向第二油腔312流动,从而通过油活塞33将活塞杆32向上顶出,直至第一油腔311的油压、第二油腔312的油压和气腔313的气压三者达到平衡,或者,第一油腔311内无液体,第二油腔312的油压和气腔313的气压二者达到平衡;在骑行的情况下,骑行者的重力或者震动力通过车架2作用于单筒阻尼减震器3,活塞杆32带动油活塞33向下滑动,第二油腔312的油压大于气腔313的气压,第二油腔312的油压作用于浮游塞34,浮游塞34向下滑动以压缩气体,同时由于油活塞33的向下滑动,将导致第一油腔311的容油空间变大,油压降低,第二油腔312内的液体将通过阻尼阀35向第一油腔311流动,直至第一油腔311的油压、第二油腔312的油压和气腔313的气压三者达到平衡。Taking the direction shown in Figure 3 as a reference, in the above-mentioned single cylinder damping shock absorber 3, the gas is sealed in theair chamber 313, and the liquid (hydraulic oil) is sealed in thefirst oil chamber 311 and thesecond oil chamber 312, and specifically Flow between thefirst oil chamber 311 and thesecond oil chamber 312 through thedamping valve 35, because thepiston rod 32 is located in thefirst oil chamber 311 to occupy a certain space, which will cause the oil holding cross section of thefirst oil chamber 311 to be smaller than The oil holding cross section of thesecond oil cavity 312 . When not riding, the air pressure in theair chamber 313 acts on thefloating plug 34, and thefloating plug 34 slides upward to compress the liquid. , the liquid in thefirst oil chamber 311 will flow to thesecond oil chamber 312 through thedamping valve 35, thereby pushing thepiston rod 32 upwards through theoil piston 33 until the oil pressure of thefirst oil chamber 311 and thesecond oil chamber 312 The oil pressure of theoil chamber 313 and the air pressure of theair chamber 313 are balanced, or there is no liquid in thefirst oil chamber 311, and the oil pressure of thesecond oil chamber 312 and the air pressure of theair chamber 313 are balanced; The gravitational or vibration force of the walker acts on the monotube damping shock absorber 3 through theframe 2, thepiston rod 32 drives theoil piston 33 to slide downward, the oil pressure of thesecond oil chamber 312 is greater than the air pressure of theair chamber 313, and the second oil chamber The oil pressure of 312 acts on thefloating plug 34, and thefloating plug 34 slides down to compress the gas. At the same time, due to the downward sliding of theoil piston 33, the oil holding space of thefirst oil chamber 311 will become larger, and the oil pressure will decrease. The liquid in theoil chamber 312 will flow to thefirst oil chamber 311 through the dampingvalve 35 until the oil pressure of thefirst oil chamber 311 , the oil pressure of thesecond oil chamber 312 and the air pressure of theair chamber 313 are balanced.

需要说明的是,上述描述中的滑动方向,仅是为了便于理解活塞杆32、油活塞33和浮游塞34在与缸筒31的相对滑动过程中所做的方向描述,并不代表对滑动方向的限定。例如,在骑行路面不平独轮车受震时,实际是电机轮1向上或下移动的,即在实际表现时,可以是缸筒31在相对移动;又例如,还可将单筒阻尼减震器3反向安装。It should be noted that the sliding direction in the above description is only for the convenience of understanding the direction description of thepiston rod 32, theoil piston 33 and the floatingplug 34 during the relative sliding process with thecylinder 31, and does not represent the direction of the sliding direction. limit. For example, when riding a unicycle on an uneven road surface, it is actually the motor wheel 1 that moves up or down, that is, in actual performance, thecylinder barrel 31 may be relatively moving; 3 reverse installation.

可以理解的是,不管活塞杆32相对缸筒31是伸出还是收缩,由于第一油腔311和第二油腔312的油压需要趋向平衡,通过阻尼阀35的作用,液体可以由第一油腔311向第二油腔312流动,也可由第二油腔312向第一油腔311流动,因此,阻尼阀35在该单筒阻尼减震器3中所起到的是双向阻尼功能。It can be understood that no matter whether thepiston rod 32 is extended or contracted relative to thecylinder barrel 31, since the oil pressures in thefirst oil chamber 311 and thesecond oil chamber 312 need to tend to balance, through the function of the dampingvalve 35, the liquid can flow from thefirst oil chamber 311 to thesecond oil chamber 312. Theoil chamber 311 flows to thesecond oil chamber 312 , and can also flow from thesecond oil chamber 312 to thefirst oil chamber 311 . Therefore, the dampingvalve 35 plays a bidirectional damping function in the single cylinder dampingshock absorber 3 .

如此,通过上述方案,通过浮游塞34将油气分离,气体通过浮游塞34压缩液体顶出活塞杆32,形成弹性减震功能,同时,通过导通第一油腔311和第二油腔312的阻尼阀35的作用,形成双向阻尼功能,将阻尼功能和减震功能集成到单筒阻尼减震器3上,实现阻尼减震一体化,其结构简单,整体占用空间小。In this way, through the above scheme, the oil and gas are separated through the floatingplug 34, and the gas compresses the liquid through the floatingplug 34 and pushes out thepiston rod 32, forming an elastic damping function. The function of the dampingvalve 35 forms a two-way damping function, and integrates the damping function and the shock absorption function into the monotube dampingshock absorber 3 to realize the integration of damping and shock absorption. Its structure is simple and the overall footprint is small.

参阅图1和图2,在本实施例中,单筒阻尼减震器3具有两个,两单筒阻尼减震器3竖直布置且分别位于电机轮1的两侧,单筒阻尼减震器3的一端固接于电机轮1的轮轴,单筒阻尼减震器3的另一端固接于车架2,在本实施例中,直接以单筒阻尼减震器3作为支撑构件,起到双边减震和承托的作用,减少零部件数量。Referring to Fig. 1 and Fig. 2, in this embodiment, there are two monotube dampingshock absorbers 3, and the two monotube dampingshock absorbers 3 are arranged vertically and are respectively located on both sides of the motor wheel 1, and the monotube damping shock absorbers One end of thedevice 3 is affixed to the wheel shaft of the motor wheel 1, and the other end of the monotube dampingshock absorber 3 is affixed to thevehicle frame 2. In this embodiment, the monotube dampingshock absorber 3 is directly used as a supporting member. To achieve the role of bilateral shock absorption and support, reduce the number of parts.

需要说明的是,封油垫片362位于限压油孔335远离第二油腔312的一侧,即该限压阀36起到的是单向泄压作用,单向泄压时,第二油腔312的液体通过限压阀36流入第一油腔311。如此设置的意义在于,在骑行者开始骑上独轮车时,由于人体重力作用,活塞杆32带动油活塞33快速下滑,并通过浮游塞34压缩气体,此时的第二油腔312的油压与第一油腔311的油压相关较大,液体能够顶开封油垫片362,实现液体由第二油腔312向第一油腔311的快速流动,使得第一油腔311的油压、第二油腔312的油压和气腔313的气压三者快速达到平衡,快速地达到安稳骑行的状态。It should be noted that theoil sealing gasket 362 is located on the side of the pressure-limitingoil hole 335 away from thesecond oil chamber 312, that is, the pressure-limitingvalve 36 plays the role of one-way pressure relief. The liquid in theoil chamber 312 flows into thefirst oil chamber 311 through thepressure limiting valve 36 . The significance of such setting is that when the rider starts to ride the unicycle, due to the action of human body gravity, thepiston rod 32 drives theoil piston 33 to slide down rapidly, and the gas is compressed through the floatingplug 34. At this time, the oil pressure of thesecond oil chamber 312 is the same as The oil pressure of thefirst oil chamber 311 is highly correlated, and the liquid can push against the unsealedoil gasket 362 to realize the rapid flow of liquid from thesecond oil chamber 312 to thefirst oil chamber 311, so that the oil pressure of thefirst oil chamber 311 and thesecond oil chamber 311 The oil pressure of the twooil chambers 312 and the air pressure of theair chamber 313 quickly reach a balance, and quickly reach a stable riding state.
