Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a knob detection system for fitness equipment. Background Art

[0002] Fitness equipment is often classified into two categories: single-function and comprehensive multi-function according to the number of training functions. Commonly used ones include rowing machines, exercise bikes, steppers, treadmills, etc. In order to meet the usage needs of different users, most fitness equipment is equipped with adjustable mechanisms, such as seat angle adjustment, seat height adjustment, handlebar height adjustment, and armrest height adjustment. For safety reasons, it needs to be locked after adjustment. The locking methods mostly include fixing by inserting pins or tightening with a knob. The tightness of tightening with a knob needs to be judged by the user independently. It is uncontrollable how much force each person uses to tighten the knob. It may not be tightened. Especially for people with little strength, if the knob is not tightened, there may be potential safety hazards. For example, if the armrest is not tightened and falls off, the screen may be damaged. If the hand is not held firmly, the user will lose balance and fall. If the fixed seat tube for seat adjustment is not tightened, the seat tube may suddenly slide down during exercise, and the feet and buttocks will be injured. Therefore, it is necessary to design a knob detection system that can automatically detect whether each knob is tightened before using fitness equipment, so that the user can indeed tighten each fixed knob and effectively avoid safety accidents caused by not being tightened. Content of the Utility Model

The knob body is rotatably installed on the frame of the fitness equipment and is locked by squeezing or unlocked by moving away from the height adjustment tube of the frame through the knob body. The installation housing is installed at the end where the knob body cooperates with the height adjustment tube. The knob detection module includes a pressure sensor, a micro-control unit, and an alarm prompt unit. The pressure sensor is arranged on the outer wall of the installation housing and is arranged between the knob body and the height adjustment tube. The pressure sensor is squeezed by the knob body to collect pressure data and transmit it to the micro-control unit. The micro-control unit is connected to and controls the alarm prompt unit to prompt the user whether the knob body is tightened currently.

[0006] Further, the installation housing includes an upper housing and a lower housing. The upper housing is installed at the end of the knob body. The lower housing is fixedly connected to the upper housing by screws. The micro-control unit is arranged inside the upper housing, and the pressure sensor is arranged on the outer wall of the lower housing.

[0007] Further, the alarm and prompt unit is arranged on the knob body. It is an LED lamp, which is connected and controlled by the micro-control unit to emit light for alarm and prompt. When the pressure value of the pressure sensor is lower than the threshold, the LED lamp emits red light; otherwise, it emits green light.

[0008] Further, there are two LED lamps. One is a red-light LED lamp and the other is a green-light LED lamp.

[0009] Further, the knob detection module further includes a battery. The battery is connected to the micro-control unit and supplies power to the pressure sensor, the micro-control unit, and the alarm and prompt unit.

[0010] After adopting the above technical solution, compared with the background technology, the utility model has the following advantages:

[0011] The utility model is provided with a knob detection module on the knob body. By using the knob body and the height adjustment tube on the frame of the fitness equipment, the pressure sensor is installed at the end of the knob body through the installation shell. The height adjustment tube is locked by the knob body, generating pressure and simultaneously squeezing the pressure sensor. The pressure sensor collects the squeezing force of the knob body, judges whether the force meets the requirements, and if not, gives an alarm and prompt through the alarm and prompt unit, realizing a knob detection system that can automatically detect whether each knob is locked before using the fitness equipment, enabling the user to firmly lock each fixed knob and effectively avoiding safety accidents caused by not being locked.
