    • A cooling device includes an inner sleeve with an outer surface, an outer sleeve surrounding the inner sleeve, and two end portions extending between the inner sleeve and the outer sleeve at the ends. The inner sleeve, the outer sleeve and the end portions define a peripheral space. A flow guiding structure defines N channels in the peripheral space for coolant to flow, where N is an integer equal to or greater than 1. Each channel has at least two branches, and N pairs of inlet and outlet corresponding to the N channels. The branches of each channel are in fluid communication with a respective pair of inlet and outlet. Each branch extends over a half circumferential part of the outer surface of the inner sleeve. An electric motor incorporating the cooling device is also provided.
    • 冷却装置包括具有外表面的内套筒,围绕内套筒的外套筒和在端部处在内套筒和外套筒之间延伸的两个端部。 内套筒,外套筒和端部限定外围空间。 流动引导结构在外围空间中定义了N个通道以使冷却剂流动,其中N是等于或大于1的整数。每个通道具有至少两个分支,并且N对对应于N个通道的入口和出口。 每个通道的分支与相应的一对入口和出口流体连通。 每个分支延伸到内套筒的外表面的半圆周部分上。 还提供了包括冷却装置的电动机。

    • A chair-like exercising apparatus comprises a back, a seat, front legs, rear legs, and resistance element(s) which provide a broad range of resistance force adjustable by the user for the back extension exercise. The chair back pivotally connects to the rear legs directly, and pivotally connects to the front legs or rear legs through the resistance element(s). The resistance element comprises a compress-coil-spring cylinders (or constant-force-spring devices) and the cylinder holders (or the device holders). The resistance level of the back extension exercise is adjusted by switching the interchangeable compress-coil-spring cylinders (or constant-force-spring devices) of appropriate loads inside the cylinder holders (or device holders). A user sits on the chair and sway backward to perform back extension exercise after selecting an appropriate resistance level based on his/her physical condition. The apparatus is simple, affordable and can be used as a regular chair in its locked position. A regular back extension exercise with proper resistance force strengthens the low back muscles (erector spinae), improves and prevents the low back pain symptoms.
    • 一种椅子式运动装置包括一个背部,一个座椅,前腿,后腿和电阻元件,它们提供由用户可调整的用于后伸展运动的宽范围的阻力。 椅子后部可直接枢转地​​连接到后腿,并通过电阻元件枢转地连接到前腿或后腿。 电阻元件包括压缩螺旋弹簧缸(或恒力弹簧装置)和气缸保持器(或装置保持器)。 通过在气缸保持器(或装置保持器)内切换适当负载的可互换的压缩螺旋弹簧气缸(或恒力弹簧装置)来调节后伸展运动的阻力水平。 用户坐在椅子上并向后摇摆,根据他/她的身体状况选择适当的阻力水平后进行后伸展运动。 该设备简单,价格合理,可用作其锁定位置的常规椅子。 经过适当阻力的正规后伸运动可加强腰背肌(竖肌),改善并防止腰痛症状。

    • An electric vehicle driving system includes an energy-storage apparatus (1), a first motor (2), a speed regulating motor (3) and a single row planetary mechanism. Said first motor (2) and said speed regulating motor (3) are connected electrically to the energy-storage apparatus (1). The single row planetary mechanism includes a sun gear (4), a gear ring (5) and a planetary carries (6) with planetary gears (7). The planetary gears (7) in the planetary carrier (6) mesh the gear ring (5) and the sun gear (4) separately. The output axle of the first motor (2) is connected to the gear ring (5), and the output axle of the speed regulating motor (3) is connected to the sun gear (4) by a brake (8). The invention takes the speed regulating motor and the single row planetary mechanism instead of the gearbox in a transmission driving system, and achieves a simple and compact structure, easy assemble, light weight, and low manufacturing cost. With the speed regulation of the speed regulating motor, the first motor works in high efficiency speed range, which increases energy utilization rate and endurance mileage.
    • 电动车辆驱动系统包括储能装置(1),第一马达(2),调速马达(3)和单列行星机构。 所述第一马达(2)和所述调速马达(3)与所述储能装置(1)电连接。 单列行星机构包括具有行星齿轮(7)的太阳轮(4),齿圈(5)和行星齿轮架(6)。 行星架(6)中的行星齿轮(7)分别啮合齿轮环(5)和太阳齿轮(4)。 第一马达(2)的输出轴连接到齿圈(5),调速马达(3)的输出轴通过制动器(8)连接到太阳齿轮(4)。 本发明采用调速电动机和单行行星机构代替传动驱动系统中的齿轮箱,实现了结构简单紧凑,组装方便,重量轻,制造成本低。 随着调速电机的调速,第一台电机工作在高效率的转速范围,提高了能量利用率和耐用里程。
