Description
Technical Field
The invention relates to the technical field of electric treadmills, in particular to an electric treadmill, a wireless intelligent safety lock and a corresponding operation method.
Background
With the updating of the public's health consciousness concept, the beneficial effects of sports on physical health have been agreed. Running is a simple and effective exercise mode, and many people develop a habit of regular running. When outdoor sites are unsuitable for running due to weather or pollution, many people choose to run with the motorized treadmill in a gym or other room.
At present, the electric running machine has potential safety hazards, for example, in complex occasions of personnel such as gymnasiums, the running machine is used as public equipment, a user often holds the running machine handrail when not want to continue exercising, jumps to the pedal, then walks down the running machine, puts the running machine to be operated regardless of the situation, and if other users want to use the running machine, the running machine does not carefully observe the running belt state, and directly steps on the running belt, so that the situation of falling down or even falling injury is most likely to occur. Similar dangerous situations often occur in occasions such as body-building equipment exhibitions.
In addition, the user moves on running and belongs to passive movement speed conversion, when the running belt speed becomes high due to misoperation of the user or faults of the running machine, if the user cannot keep up with the running belt speed, the user falls down from the running machine and falls down to hurt, and if the running belt of the running machine is not stopped in time, the user also has the risk that hair or clothes are wound into the inner side of the running belt. If the user loses consciousness after falling down the running machine, a certain body part of the user is still in contact with the running belt, and secondary injury can be caused to the user under the condition that the user is not timely rescued.
Safety locks, also known as safety switches, emergency stop switches, anti-fall emergency stop switches are one of the most important components on electric treadmills. The safety lock is used for guaranteeing that a user can cut off the power supply of the motor of the running machine instantly when carelessly falling down or other unexpected situations occur in the running machine using process, and the running belt driven by the motor is stopped to run, so that personal injury is avoided.
The safety locks equipped for running machines at present are mainly divided into two types: one is that the magnetic attaches the line pull-out type safety lock that presss from both sides, and the one end that the line pull-out type safety lock is pressed from both sides on the treadmill control cabinet through magnet, and the other one end takes the clip to press from both sides on user's clothes, when unexpected emergence, pulls away the safety lock from the treadmill and cuts off the motor power of treadmill. The other is a hand-clapping type safety lock: when accidents happen, a user presses the safety lock hard to turn off the power supply of the motor of the running machine.
Most users have little knowledge of the safety lock of the treadmill and have little consciousness of self-protection, and for the wire-clamping safety switch, the running is affected due to the fact that a string is blocked between clothes and the treadmill, so that many users do not want to clamp the safety lock. In addition, because of the panic mind when the danger occurs, the user can not start the sudden stop device of the running machine in time when the danger occurs, so that the traditional sudden stop device can not always work, and as a result, the injury event of the user of the electric running machine can often occur.
In summary, the traditional treadmill safety lock has a great potential safety hazard.
