Description
本发明涉及平衡车控制领域，更具体的说，涉及一种平衡车车轮固定结构与平衡车。The present invention relates to the field of balance vehicle control, and more particularly to a balance vehicle wheel fixing structure and a balance vehicle.
电动平衡车，又叫体感车、思维车，其运作原理主要是建立在一种被称为“动态稳定”的基本原理上，利用车体内部的陀螺仪和加速度传感器，来检测车体姿态的变化，利用伺服控制***，精确地驱动电机进行相应的调整，以保持***的平衡。Electric balance car, also known as body car, thinking car, its operation principle is mainly based on a basic principle called "dynamic stability", using the gyroscope and acceleration sensor inside the car body to detect the posture of the car body. Change, using the servo control system, accurately drive the motor to adjust accordingly to maintain the balance of the system.
现有的电动平衡车一般有两种，一种是车体上具有一个操作杆，使用者站在电动平衡车的脚踏平台上对操作杆进行操作，从而前进、后退及停止，这样的控制也称“手控”。另一种是车体由两部分组成，左部分和右部分之间通过转动机构实现相互转动，从而实现“脚控”。There are two types of electric balance vehicles in the prior art. One type has an operating lever on the vehicle body, and the user stands on the pedal platform of the electric balance vehicle to operate the operating lever to advance, retreat and stop. Also known as "hand control." The other is that the car body is composed of two parts, and the left part and the right part are mutually rotated by the rotating mechanism, thereby realizing "foot control".
现有的平衡车车辆比较占用地方，在不使用的时候需要占用较大的空间。且车轮容易滚动，而平衡车又没有停车刹车装置，因此也容易走位。The existing balance car vehicles occupy a larger place and require a larger space when not in use. And the wheels are easy to roll, and the balance car has no parking brakes, so it is easy to move.

本实施方式公开一种平衡车，所述平衡车包括车体；所述车体设有车轮固定结构。所述车轮固定结构包括空心管体；空心管体内套设有活动轴和第一卡扣；车轮的轮轴可套设进入空心管体内部；所述活动轴一端与轮轴活动连接，另一端在轮轴收纳进空心管体内时与第一卡扣配合固定；空心管体开口处设有在车轮折叠时与轮轴侧壁配合固定的第二卡扣。卡扣应该从广义理解，传统意义上的插销、卡簧等可用于卡位固定的结构都应该在本发明卡扣的范围内。The embodiment discloses a balance vehicle, and the balance vehicle includes a vehicle body; and the vehicle body is provided with a wheel fixing structure. The wheel fixing structure comprises a hollow pipe body; the hollow pipe body is sleeved with a movable shaft and a first buckle; the wheel axle of the wheel can be sleeved into the hollow pipe body; one end of the movable shaft is movably connected with the axle, and the other end is at the axle When being inserted into the hollow tube body, the first buckle is fixedly engaged; the hollow tube body opening is provided with a second buckle that is fixedly coupled with the sidewall of the axle when the wheel is folded. The buckle should be understood in a broad sense, and the conventionally used latches, circlips, etc., which can be used for the fixing of the card position, should be within the scope of the buckle of the present invention.
可选的，空心管体的开口处套设有帽套；所述帽套的孔径小于空心管口的内径；第二卡扣固定在帽套上。帽套通过螺纹固定在空心管体开口处。通过帽套可以方便活动轴、轮轴的拆装。Optionally, the opening of the hollow tubular body is sleeved with a cap; the diameter of the cap is smaller than the inner diameter of the hollow nozzle; and the second buckle is fixed on the cap. The cap is threaded to the opening of the hollow body. The movable shaft and the axle can be easily disassembled and assembled by the cap.
帽套内部顶面和底面均为平面；相应的，活动轴上表面和下表面也是平面，与帽套内部顶面和底面配合形成限制活动轴转动的限位结构。利用帽套的内径形状对活动轴进行限位，防止转轴转动，这样无须再空心管体内设置限位结构，降低生产制造成本。
The top surface and the bottom surface of the cap are both flat; correspondingly, the upper surface and the lower surface of the movable shaft are also flat, and cooperate with the top surface and the bottom surface of the cap to form a limit structure for restricting the rotation of the movable shaft. The inner diameter of the cap is used to limit the movable shaft to prevent the rotating shaft from rotating, so that the limit structure is not required in the hollow tube body, and the manufacturing cost is reduced.
所述轮轴的长度大于所述帽套的口径。这样转轴与帽套垂直的时候，即在车轮折叠的时候利用第二卡扣卡在帽套开口处帽套开口处，实现自动定位。The length of the axle is greater than the diameter of the cap. When the rotating shaft is perpendicular to the cap, that is, when the wheel is folded, the second snap is used to obtain the automatic opening of the cap opening at the opening of the cap.
所述活动轴与轮轴固定的一端设有凹槽；所述凹槽两内壁之间设有转轴；相应的，所述轮轴嵌入凹槽内；所述轮轴设有套设转轴的通孔；当轮轴转动到与活动轴平行时，转轴可连同活动轴嵌入到空心管体内部；当转轴转动到与活动轴垂直时，转轴通过第二卡扣固定在帽套开口处。a fixed end of the movable shaft and the axle is provided with a groove; a rotating shaft is disposed between the inner walls of the groove; correspondingly, the axle is embedded in the groove; the axle is provided with a through hole for the rotating shaft; When the axle is rotated parallel to the movable shaft, the rotating shaft can be embedded inside the hollow pipe body together with the movable shaft; when the rotating shaft is rotated perpendicular to the movable shaft, the rotating shaft is fixed at the opening of the cap through the second buckle.
轮轴包括与所述凹槽配合的固定部，与固定部连接的基座；所述活动轴在凹槽一端的端面为内凹弧面；所述基座与固定部连接处设有与内凹弧面适配的外凸弧面。弧面有利于转动轮轴时降低摩擦。The axle includes a fixing portion that cooperates with the groove, and a base that is coupled to the fixing portion; an end surface of the movable shaft at one end of the groove is a concave curved surface; and a joint of the base and the fixing portion is provided with a concave portion The convex curved surface of the curved surface. The curved surface helps to reduce friction when turning the axle.
所述活动轴与轮轴相对的一端连接有圆盘；所述圆盘的外径与空心管体的内径一致。One end of the movable shaft opposite to the axle is connected with a disc; the outer diameter of the disc is identical to the inner diameter of the hollow tubular body.
可选的，本发明也并非一定要帽套，直接在空心管体内部形成弹簧和活动轴的定位结构也是可行的。这样部件更少，结构更紧凑一些。具体来说，空心管体内部采用非圆形结构，可以采用椭圆形、矩形等，当然，也可以在内部的顶面和底面设置为平面；相应的，活动轴上表面和下表面也是平面，与空心管体内部顶面和底面配合形成限制活动轴转动的限位结构。此时，轮轴的长度大于所述空心管体的内径。活动轴、轮轴等结构可以参考前面描述，在此不再赘述。Alternatively, the present invention does not necessarily have a cap, and it is also feasible to form a positioning structure of the spring and the movable shaft directly inside the hollow pipe body. There are fewer parts and a more compact structure. Specifically, the hollow pipe body adopts a non-circular structure, and may adopt an elliptical shape, a rectangular shape, or the like. Of course, the top surface and the bottom surface of the inner hollow body may be arranged as a plane; correspondingly, the upper surface and the lower surface of the movable shaft are also flat. Cooperating with the top surface and the bottom surface of the hollow pipe body to form a limit structure for restricting the rotation of the movable shaft. At this time, the length of the axle is greater than the inner diameter of the hollow tubular body. For the structure of the movable shaft and the axle, reference may be made to the foregoing description, and details are not described herein again.
与现有技术相比，本发明的技术效果是：本发明利用空心管体、活动轴和第一卡扣、第二卡扣的配合实现平衡车车轮折叠。在正常使用时，转动轮轴跟活动轴平行，活动轴、轮轴可以嵌入到空心管体内，并通过第一卡扣定位，防止水平位置滑动，此时轮胎跟空心管体垂直，为正常行驶状态。折叠车轮时，拉动车轮，使转轴全部露出空心管体，然后转到轮轴，使其与活动轴垂直，此时车轮与空心管体平行，处以折叠状态。通过跟第二卡扣配合，轮轴卡在空心管体的开口处定位，维持车轮折叠状态。另外，整个折叠结构都能容纳到空心管体内，空间占用极小，能适用于不同款式的平衡车。
Compared with the prior art, the technical effect of the present invention is that the present invention utilizes the cooperation of the hollow pipe body, the movable shaft and the first buckle and the second buckle to realize the folding of the balance wheel. In normal use, the rotating axle is parallel to the movable shaft, and the movable shaft and the axle can be embedded in the hollow tube body and positioned by the first buckle to prevent the horizontal position from sliding. At this time, the tire is perpendicular to the hollow tubular body and is in a normal driving state. When folding the wheel, pull the wheel so that the shaft is completely exposed to the hollow tube body, and then turn to the axle to make it perpendicular to the movable shaft. At this time, the wheel is parallel with the hollow tube body and folded. By engaging with the second snap, the axle card is positioned at the opening of the hollow tubular body to maintain the folded state of the wheel. In addition, the entire folding structure can be accommodated in the hollow tube body, the space is very small, and can be applied to different styles of balance cars.
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
The above is a further detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
