Detailed implementation manners

[0025] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0026] Embodiment 1

[0027] Referring to Figures 1 to 5 , a kind of overhead rail weight loss training device described in this embodiment includes an overhead rail 1 and a trolley. A groove penetrating along the length direction is opened on the overhead rail 1, and the groove opens downward and is matched with the trolley. The groove is divided into three layers, which are respectively matched with the movement stability component, the power generation component and the traveling component of the trolley from top to bottom.

[0028] Mounting bars 8 are installed on both sides of the inner wall of the middle layer of the groove of the overhead rail 1. Conductive bars 7 are installed inside the mounting bars 8. The two groups of conductive bars 7 are respectively connected to the positive and negative poles of the power supply. Taking the central axis of the overhead rail 1 as the inner side, the two conductive bars 7 face the outside of the overhead rail 1. The trolley includes a mounting plate 2. Conductive wheels 6 are rotatably installed on both sides of the mounting plate 2. A contraction elastic member 9 is installed between the two conductive wheels 6 on both sides. The two conductive wheels 6 are in interference fit with one conductive bar 7 respectively to transmit current. The contraction elastic member 9 is always in a contracted state, pulling the two groups of conductive wheels 6 inward to ensure that the conductive wheels 6 are always in contact with the conductive bars 7, avoiding virtual connection. A storage battery is installed on the trolley. The conductive wheels 6 charge the storage battery through conductive sheets and data lines. The storage battery supplies power to the entire trolley to drive the trolley to travel and train.

[0029] A set of traveling wheels 3 are respectively installed at both ends of the mounting plate 2 along the length direction. The two groups of traveling wheels 3 are driven by a drive assembly 4 installed on the mounting plate 2 to roll along the inner wall of the bottom layer of the overhead rail. The drive assembly 4 is powered by the storage battery.

[0030] Preferably, the driving component 4 includes a motor driven by a storage battery. A set of driving gears is installed on the output end of the motor. There is also an odd number of driven gears, which are five sets as shown in the figure. The driving gear meshes with one set of driven gears, and multiple sets of driven gears mesh with adjacent gears respectively. The two walking wheels 3 are coaxially connected to the driven gears on both sides respectively. The motor drives the driving gear to rotate, and the driving and driven gears drive the driven gears to rotate, thereby driving the two walking wheels 3 to rotate in the same direction, and rolling in the bottom groove of the overhead rail 1 to drive the trolley to move.

[0031] When the patient uses or stops training, it is necessary to ensure that the trolley is stationary to prevent the patient from falling due to inconvenient operation. Therefore, a parking component needs to be added to prevent the walking wheels 3 from moving when they need to be stationary.

[0032] The parking component includes a metal ring 13 installed on the rim of the walking wheel 3. An installation rod 10 is installed on the installation plate 2, and an elastic piece 11 is installed on the installation rod 10. An electromagnet 12 is installed on one side of the end of the elastic piece 11 close to the metal ring 13. The electromagnet 12 is electrically connected to the storage battery through a data cable. When parking is required, the storage battery supplies power to the electromagnet 12, and the electromagnet 12 approaches the metal ring 13 until it attracts and engages with the metal ring 13, preventing the walking wheel 3 from continuing to rotate. At this time, the end of the elastic piece 11 follows the electromagnet 12 and approaches the walking wheel 13.

[0033] A correction wheel 5 is rotatably installed at each end of the installation plate 2 along the length direction, and the axis of the correction wheel 5 is along the vertical direction. The correction wheel 5 rolls relative to the inner wall of the overhead rail 1 at the turning point of the conductive sheet, and corrects the deviation of the trolley at the turning point.

[0034] Since the overhead rail 1 is at a relatively high position in the air, when there is an object blocking the travel of the walking wheels 3 or a failure occurs on the walking wheels 3 themselves, it is impossible to observe immediately. At this time, the walking may be bumpy, causing the patient to feel weightlessness and seriously causing physical harm. Therefore, a moving stability component is also installed between the overhead rail 1 and the trolley. The moving stability component includes a vertical balance member 18 and a horizontal balance member 15, and the vertical balance member 18 and the horizontal balance member 15 expand and contract in the vertical and horizontal directions respectively.

[0035] The vertical balance member 18 includes an installation frame 181 and a T-shaped rod 183. A moving wheel 19 is installed at the top of the installation frame 181, and the moving wheel 19 rolls on the inner wall of the top layer of the overhead rail 1. The top of the T-shaped rod 183 is a flat plate, and a vertical rod is installed in the middle of the flat plate. A vertical elastic member 182 is installed between the flat plate of the T-shaped rod 183 and the inner wall of the installation frame 181. Preferably, the vertical elastic member 182 is a spring. The vertical rod is inserted into the spring and passes through the bottom end of the installation frame 181 and is rotatably installed with two sets of rotating rods 17. The two sets of rotating rods 17 are opposite to each other and have the same length direction. The other ends of the two sets of rotating rods 17 are both rotatably installed with a set of connecting plates 14. The two sets of connecting plates 14 are respectively installed on both sides of the installation plate 2. A horizontal elastic member 16 is installed between the two sets of connecting plates 14.

[0036] Working principle: The storage battery drives the walking wheels 3 to move along the overhead rail 1 through the driving assembly 4. Driven by the mounting plate 2, the two conductive wheels 6 rotate and are in interference fit with the conductive strips 7 on both sides respectively, continuously charging the storage battery, thereby reducing the endurance requirement for the storage battery and ensuring sufficient power at the same time. During the movement of the trolley, if it encounters a bend, the correction wheel 5 corrects the deviation of the trolley to prevent the walking wheels 3 from deviating too much. When the patient needs to rest, wear or stop using, the electromagnet 12 is energized and attracted to the metal ring 13 to lock the walking wheels 3, ensuring the stability of the trolley in the stopped state. When encountering an obstacle or a flat tire of the walking wheels 3, the T-shaped rod 183 and the rotating rod 17 rotate relative to each other, and the vertical elastic member 182 provides buffering in the vertical direction to avoid sudden lowering or lifting on one side, giving the trolley buffer time. At the same time, the horizontal elastic member 16 provides buffering in the horizontal direction to avoid sudden imbalance on one side, thereby ensuring the smoothness of the patient during walking and improving the comfort of use.
