Description

Bidirectional electric treadmill based on same safety switch and installation and use method thereof

Technical Field

A two-way electric treadmill based on the same safety switch and an installation and use method thereof belong to the field of fitness equipment, in particular to a two-way electric treadmill based on the same safety switch and an installation and use method thereof.

Background

Two-way electric treadmills, namely: the electric running machine can perform forward running movement and backward running movement towards the control panel of the electric running machine on the same electric running machine. The method for making the electric treadmill capable of only normally facing the control panel of the electric treadmill to perform the forward running exercise as the bidirectional treadmill comprises the following steps: firstly, the rotation direction of the motor of the electric treadmill is controlled to be reversed by a control system of the electric treadmill (the method is mentioned in the invention patent 'electric treadmill capable of bidirectional movement' with the application number of 'CN 201710056216.3' and the publication number of 'CN 107174784A'); and secondly, the rotating direction of the motor of the electric treadmill is reversed by a method of interchanging a live wire and a zero wire (also called as a positive pole and a negative pole) at the power output end of the lower control board of the electric treadmill.

In order to prevent the situation that the sporter cannot keep up with the running belt of the treadmill due to the speed of the sporter during the forward running exercise on the electric treadmill, and then throws the sporter out of the running platform, causing the exercise injury, the existing electric treadmill is basically configured with a safety switch (also called a safety key or an emergency switch, etc., hereinafter collectively referred to as a safety switch), and the principle of the safety switch is as follows: the switch is arranged on the control panel of the electric treadmill, the safety rope with a proper length is connected to the switch, the other end of the safety rope is connected with the safety clamp, the electric treadmill clamps clamp clothes or trousers worn by an exerciser before running, when the exerciser cannot keep up with the running speed of the treadmill, the distance between the exerciser's human body and the control panel of the electric treadmill can be increased, meanwhile, the safety clamp on the clothes or trousers worn by the exerciser can move backwards and gradually straighten the safety rope, when the distance between the exerciser's human body and the control panel of the electric treadmill reaches a certain distance, the completely straightened safety rope can pull the switch button, thereby disconnecting the electric treadmill and stopping the running of the treadmill.

The magnetic switch intrusion detector consists of permanent magnet and dry reed pipe. The reed switch is a magnetic control switch, which is arranged on the control panel of the electric treadmill and is provided with a movable magnet block, and the magnet block is close to and far from the reed switch to achieve the effect of opening or closing a circuit.

Because the eyes of the sporter can not see the place where the feet step on, when the sporter walks backwards, the safety becomes a problem when the sporter walks backwards on the existing common electric back-walking machine (the electric back-walking machine is also an electric running machine which only changes the rotation direction of the motor of the electric back-walking machine), therefore, several safety control methods of the back-walking movement are disclosed, such as: the invention patent with the application number of CN201710056216.3 and the publication number of CN107174784A discloses an electric running machine capable of moving in two directions, which is provided with a warning area and a detection device (unit), detects the position of a sporter on a running platform by using methods such as infrared rays, ultrasonic waves, treading sensing and/or image identification and the like, and further triggers a safety reaction mechanism of a control unit when the human body of the sporter enters the area so as to control the method of slowing down or stopping the running belt to increase the safety factor of the back-running movement; also, as disclosed in the invention application "electric back-off device capable of normally operating based on safety and safety control method thereof" published by the inventor as "CN 201910259089.6" and "CN 109865248A", a method for limiting a back-off sporter from gripping a grab bar with one or both hands and/or binding a safety belt to perform back-off movement to achieve the purpose of safety is disclosed.

However, regardless of the conventional backward walking exercise safety control method, when the backward walking exercise is performed in the front direction of the electric back-up walking machine (i.e., the direction of the control panel) in the conventional electric back-up walking machine, the safety switch (see 160, 172 and 174 in fig. 1, 2 and 3 of the invention patent with the application number "CN 201710056216.3", which are well known) which is basically configured to ensure the safety of the forward walking and running in the conventional electric running machine does not work any more, and thus, the safety switch is a type of arrangement and is a waste in fact. And no matter which kind of the safety control method of the back-walking movement is adopted, various new detection sensing devices must be added, such as: infrared emitter and receiver, ultrasonic emitter and receiver, pressure sensor etc. not only greatly increased the cost, also increased the degree of difficulty such as installation, maintenance when using.

Then, a method that cannot achieve an increase in the safety factor of the backward walking exercise using the safety switch basically provided in the electric treadmill when the backward walking exercise is performed on the control panel facing the electric backward walking machine?
