Description

Weight-bearing device for fitness equipment

The invention relates to a weight-bearing device, especially a weight-bearing device for fitness equipment.

Referring to FIG. 1, a traditional weight-bearing device 1 used for fitness equipment 2 includes a frame 11, a plurality of load-bearing blocks 12 placed in the frame 11, and an adjustment to control the pulling quantity of the load-bearing blocks 12 13. The load-bearing device 1 mainly uses the load-bearing block 12 as a load, and the position of the adjusting member 13 adjusts the number of the load-bearing blocks 12 to be pulled. The user can select an appropriate number of the load-bearing blocks 12 according to their physical fitness During exercise, it pulls the load block 12 to rise in the frame 11 by operating the fitness equipment 2 to achieve the purpose of muscle strength and muscle endurance training; however, the conventional load device 1 mainly drives the load The size of the blocks 12 is adjusted. Therefore, the load-bearing blocks 12 must be placed on the frame 11 of the load device 1 and the range of movement of the load-bearing blocks 12 must be provided. Therefore, the frame 11 needs a relatively large volume to be sufficient for these The space for the placement and movement of the load-bearing block 12 will be too large and occupy space. Each load-bearing block 12 has a fixed weight. The relative number of segments can only be provided based on the multiple of the load block 12, and the load cannot be fine-tuned, resulting in a load. Inconvenience in adjustment.

Moreover, when the load-bearing block 12 is mounted, the greater the inertial force of the gravitational acceleration generated at the time of the return stroke is, and it is easy to cause sports injuries due to the inertial force. At the same time, it is inevitable that the load-bearing block 12 will be in the process of moving. Noise is generated due to collisions, causing the athletes to feel harsh or uncomfortable with the noise. Therefore, it is necessary to improve.

Therefore, the purpose of the present invention is to provide a weight-bearing device for fitness equipment, which can reduce the size, reduce the noise in use, and improve the safety and convenience of use.

Therefore, the weight-bearing device for fitness equipment of the present invention includes a housing, a driving device arranged in the housing, and a linkage device arranged in the housing and linked with the driving device; wherein, the driving device It includes a drive motor provided in the housing and a controller for controlling the rotation of the drive motor; in addition, the linkage device has a drive belt provided in the housing and connected with the drive motor, and a drive belt is linked by the drive belt.

Therefore, the overall volume can be reduced, and the noise of the load block collision can be avoided, and the output of the drive motor can be quickly controlled through the controller. The torque can be adjusted quickly and conveniently beyond the required pulling force, and through the driving method of the drive motor, it can avoid the inertia force causing injury and improve the safety of use.

The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings.

2 and 3, in the first preferred embodiment of the present invention, the weight-bearing device 3 for fitness equipment includes a housing 31, a driving device 32 arranged in the housing 31, and a driving device 32 arranged in the housing 31 and the linkage device 33 linked with the driving device 32; wherein, the housing 31 is formed with an accommodating space 311, and the housing 31 is provided with at least one opening for the accommodating space 311 and the external space 312; In addition, the driving device 32 includes a driving motor 321 provided in the housing 31, and a controller 322 that controls the rotation of the driving motor 321, and the driving motor 321 can be a DC motor in actual use, and The controller 322 can control the output current to the driving motor 321, thereby adjusting and controlling the output torque and the rotation speed of the driving motor 321.

2 and 3, when this embodiment is activated, after the drive motor 321 is controlled to rotate through the controller 322, the drive motor 321 will drive the transmission belt 331 to move, and at the same time the drive belt 331 will drive the linkage wheel. 332 rotates, and the interlocking wheel 332 rotates in conjunction with the force-receiving wheel 333 during the rotation. At this time, the force-receiving belt 334 wound on the force-receiving wheel 333 will be affected by the force-receiving wheel 333. 333 rotates and rewinds. At the same time, because the end of the stressed belt 334 is restricted by the positioning block 335, the stressed belt 334 will assume a tensioned state, so that the stressed wheel 333 is fixed by the stressed belt 334, together with The interlocking wheel 332, the transmission belt 331, and the drive motor 321 are in a stopped state. When the controller 322 continues to control the output torque of the drive motor 321, the output torque of the drive motor 321 will remain constant, and the force will be The belt 334 bears the pulling force of the driving motor 321 relative to the torque force, and the pulling force can be used as the weight required for fitness. Therefore, the controller 322 controls the driving motor 321 to output torque force, which can be easily and quickly , Precise adjustment of the weight required for fitness, does not need to be adjusted by increasing or reducing the weight as known, so in addition to reducing the overall volume and use space of the weight-bearing device 3, it can also avoid the conventional weight-bearing during the actuation process. Noise caused by collision or placement of blocks.
