常見的旅行箱包一般都安裝有腳輪，以方便人們直接拖動箱包。傳統的旅行箱包的腳輪對於減震效果缺乏考慮，當箱包被拖行過程中，如果經過凹凸不平的路面時，會引起箱包劇烈震動，容易造成箱包內部物品破壞，而且也會導致箱包過早損壞。Common travel luggage is generally equipped with casters to facilitate people to drag the luggage directly. Traditional travel luggage casters lack consideration for the shock absorption effect. When the luggage is towed over uneven roads, it will cause violent vibrations in the luggage, easily causing damage to the items inside the luggage, and also causing premature damage to the luggage. .

上揭習知箱包減震腳輪結構中，是通過在其支撐桿下部設置有置於空腔底部的減震彈簧，在遇到路況不好時，只能通過設置在支撐桿下部的彈簧來進行減震，故減震效果較差。因此，有必要對現有技術進行改進，以使其更為完善實用。In the conventional luggage shock-absorbing caster structure, a shock-absorbing spring placed at the bottom of the cavity is provided at the lower part of the support rod. When the road conditions are bad, the shock-absorbing caster can only be relieved by the spring installed at the lower part of the support rod.

The connection end is connected to the inner wall of the rear side of the cavity. The deflection end is provided with a shaft hole for movement and a shaft rod. , and the two ends of the shaft are respectively assembled with wheels; and an elastic member is provided on the deflection end. The elastic member is in contact with the front inner wall of the cavity. After the elastic member is compressed, it can make the deflection end of the deflection connector Yaw deformation occurs after being compressed.

藉此創新結構型態與技術特徵，使本創作對照先前技術而言，俾可達到以下有益效果：（一）本創作通過在支撐座內部設置有彈性件和偏擺連接件相配合的減震結構，使得在其受到外部壓力時，偏擺連接件可以對應地支撐彈性件，兩者配合受力後能夠形成兩段變形效果，起到緩衝外部壓力的作用，從而達到更好的減震效果。（二）本創作通過偏擺連接件與軸桿連接，軸桿兩端設置有輪子，當輪子在受力後，作用力通過軸桿作用到偏擺連接件上，再通過偏擺連接件傳導給彈性件，使得受力點更靠近彈性件和偏擺連接件，彈性件受力更直接，且所揭偏擺連接件透過連接端連接在空腔後側內壁上之型態特徵，對於其偏擺動作能夠提供更為強軔的復位彈性與結構支撐性，從而輔助彈性件達到更良好的緩衝減震效果。 By innovating the structural form and technical characteristics, compared with the previous technology, this creation can achieve the following beneficial effects: (1) In this creation, a shock-absorbing structure is provided inside the support base with an elastic member and a deflection connector, so that when it is subjected to external pressure, the deflection connector can correspondingly support the elastic member, and the two cooperate to receive force.

其中，該腳輪減震結構還包括一組裝座60，令該支撐座10透過一支撐軸70旋設於該組裝座60呈可自由轉向狀態。該組裝座60則用以將腳輪組裝於一既有標的物(如行李箱、儲物箱等)結構底部。 Among them, the caster shock-absorbing structure also includes an assembly base 60, so that the support The base 10 is rotated on the assembly base 60 through a support shaft 70 so that it can be freely turned. The assembly seat 60 is used to assemble the caster at the bottom of an existing object (such as a suitcase, a storage box, etc.).

如圖3所示，本例中，該偏擺端22上設置有第一導向柱221，該彈性件50具有一第一端51以及一第二端52，其中該第一端51套接在該第一導向柱221上並與該偏擺端22抵接；且該第一導向柱221對應的該空腔11內壁上設置有一凹部12，該凹部12內設置有一第二導向柱13，該第二導向柱13與該第一導向柱221同軸對稱設置，該彈性件50之該第二端52則套接在該第二導向柱13上並抵接在該凹部12內壁上。其中該彈性件50於本例圖面中所示為螺旋彈簧。As shown in Figure 3, in this example, the deflection end 22 is provided with a first guide post 221, and the elastic member 50 has a first end 51 and a second end 52, wherein the first end 51 is sleeved on The first guide post 221 is in contact with the deflection end 22; and a recess 12 is provided on the inner wall of the cavity 11 corresponding to the first guide post 221, and a second guide post 13 is provided in the recess 12. The second guide post 13 is coaxially symmetrical with the first guide post 221 , and the second end 52 of the elastic member 50 is sleeved on the second guide post 13 and abuts against the inner wall of the recess 12 . The elastic member 50 is shown as a coil spring in this example.

如圖3所示，本例中，該第一導向柱221與該第二導向柱13係沿著一傾斜軸向設置，該傾斜軸向之傾角X介於25度至35度之間。本例所揭實施型態，主要可通過將彈性件50的傾斜設置型態特徵，以當輪子40受力後彈性件回彈的作用力靠向輪子40後側，從而在遇到路況不佳狀態時，減震後輪子40懸空的高度小，從而有效提高輪子40在行駛過程中的穩定性。As shown in FIG. 3 , in this example, the first guide post 221 and the second guide post 13 are arranged along an inclined axis, and the inclination angle X of the inclined axis is between 25 degrees and 35 degrees. The implementation disclosed in this example can mainly set the shape characteristics of the elastic member 50 by tilting it, so that when the wheel 40 is stressed, the elastic member rebounds against the rear side of the wheel 40, so that when encountering poor road conditions In this state, the suspension height of the shock-absorbing rear wheel 40 is small, thereby effectively improving the stability of the wheel 40 during driving.

如圖5所示，本例中，該第一導向柱221與該第二導向柱13係沿著一垂直軸向Z設置。本例所揭實施型態因為彈性件50的壓縮與釋放方向均在該垂直軸向Z上，所以對於箱體的向下負荷重力具有較佳緩衝避震效果。As shown in FIG. 5 , in this example, the first guide post 221 and the second guide post 13 are arranged along a vertical axis Z. The embodiment disclosed in this example has a better buffering and shock-absorbing effect on the downward load gravity of the box because the compression and release directions of the elastic member 50 are both in the vertical axis Z.

如圖1所示，本例中，該偏擺端22中間更貫穿設有一軸設孔223，令該軸桿30貫穿該軸設孔223分別連接該輪子40。As shown in FIG. 1 , in this example, an axle hole 223 is formed through the middle of the deflection end 22 , so that the axle rod 30 passes through the axle hole 223 and is connected to the wheel 40 respectively.

如圖2所示，本例中，該輪子40具有軸孔41，該軸桿30的兩端連接端上分別設置有卡接筒套80，該卡接筒套80用於卡接各該輪子40之該軸孔41，且該卡接筒套80上設置有多個均勻分佈的凸起卡塊81，該軸孔41內則對應設置有相嵌卡配合的數個卡槽42。其中該卡接筒套80可採用高耐磨材質(如PA材料，即聚醯胺，一般亦稱為尼龍)製成，作用是取代習知軸承達到簡化構件又兼具耐磨耐用。且其耗損後無須更換輪子，僅更換該卡接筒套80即可，故可大幅節省使用者的使用成本。As shown in Figure 2, in this example, the wheel 40 has an axle hole 41, and the two connecting ends of the shaft 30 are respectively provided with snap-in sleeves 80. The snap-in sleeves 80 are used to snap in each wheel. The shaft hole 41 of 40 is provided with a plurality of evenly distributed protruding blocks 81 on the clamping sleeve 80, and a plurality of slots 42 are correspondingly provided in the shaft hole 41 to fit with each other. The snap sleeve sleeve 80 can be made of a highly wear-resistant material (such as PA material, that is, polyamide, also commonly known as nylon). Its function is to replace conventional bearings to simplify components while also being wear-resistant and durable. Moreover, there is no need to replace the wheel after it is worn out, and only the clamping sleeve 80 can be replaced, so the user's usage cost can be greatly saved.

藉由上述結構組成型態與技術特徵，茲就本創作腳輪減震結構之使用作動情形說明如下：如圖4所示，當輪子40受壓時(如箭號L1所示)，與輪子40相接的偏擺連接件20受到外部壓力後相對變形偏擺上移(如箭號L2所示)，此時偏擺連接件20會施加一作用力給彈性件50，該彈性件50受壓後沿第一導向柱221和第二導向柱13的軸方向變形收縮，彈性件50受壓後的回復力再次沿第一導向柱221和第二導向柱13的方向作用到偏擺連接件20上，使得偏擺連接件20二次變形(如圖3所示狀態)，從而能夠起到更好的緩衝作用以及達到更好的減震效果。且本案中所揭偏擺連接件20透過連接端21連接在空腔11後側內壁上之型態特徵，對於其偏擺動作能夠提供更為強軔的復位彈性與結構支撐性，從而輔助彈性件50達到更良好的緩衝減震效果。Based on the above structural composition types and technical characteristics, the operation conditions of the caster shock-absorbing structure of this invention are described as follows: As shown in Figure 4, when the wheel 40 is under pressure (as shown by arrow L1), the wheel 40 The connected deflection connectors 20 are relatively deformed and deflect upward after being subjected to external pressure (as shown by arrow L2). At this time, the deflection connector 20 will exert a force on the elastic member 50, and the elastic member 50 will be compressed. After deformation and contraction along the axial direction of the first guide post 221 and the second guide post 13, the restoring force of the elastic member 50 after being compressed again acts on the deflection connector 20 in the direction of the first guide post 221 and the second guide post 13. On the other hand, the deflection connecting member 20 is deformed twice (the state shown in Figure 3), thereby providing a better buffering effect and achieving a better shock-absorbing effect. Moreover, the shape of the deflection connector 20 disclosed in this case is connected to the rear inner wall of the cavity 11 through the connecting end 21, which can provide stronger reset elasticity and structural support for its deflection action, thereby assisting The elastic member 50 achieves a better buffering and shock-absorbing effect.
