Description

Technical Field

[0001] This utility model relates to the field of motor safety braking technology, and in particular to a motor mechanical locking structure. Background Technology

[0002] In existing strength training equipment, counterweights still dominate the load-bearing capacity. However, in recent years, with the transformation of sports equipment towards digitalization and intelligence, servo motors have gradually replaced traditional counterweights as the core load-bearing device in strength training equipment. Servo motors, by adjusting output torque in real time, can accurately simulate the resistance of different exercise scenarios, resulting in lighter equipment. Combined with data acquisition and analysis functions, they provide users with personalized training feedback. Servo motors can simulate different exercise scenarios, achieving diversified development with multiple uses, greatly improving the practicality and functionality of the equipment. However, in practical applications, the power dependence of servo motors has also exposed significant safety hazards.

[0003] First, during training, a sudden power outage or interruption will cause the servo motor to instantly unload resistance due to the loss of driving force. When the user is in a high-load training state (such as lat pulldowns, squats, etc.), the sudden loss of resistance may cause the body to lose balance, leading to muscle strains or joint injuries, seriously threatening the user's safety. Second, when the equipment is not in use due to power failure, the servo motor cannot self-lock, and the rope on its reel may be pulled out by external force (such as accidental operation by a child), causing internal cables to become tangled, misaligned, or even damaged, affecting the normal start-up of the equipment or creating long-term potential for failure.

[0004] Currently, electromagnetic brakes are widely used in the industry as the braking solution for servo motors. These brakes achieve braking by using electromagnetic force to attract friction pads, but they have the following drawbacks:

[0005] Braking force decay problem: Electromagnetic brakes rely on continuous electromagnetic force to maintain braking. After long-term use, wear of the friction pads or aging of the electromagnetic coil will cause the braking force to gradually decrease, affecting braking reliability.

[0006] Response delay: When power is lost, the electromagnetic brake needs to rely on the residual electromagnetic force to complete the braking, which has a short delay and cannot achieve instantaneous locking, thus still posing a safety hazard.

[0007] Cost and maintenance: Electromagnetic brakes have a complex structure and high manufacturing costs. They also require regular replacement of wear parts such as friction plates, resulting in significant maintenance costs.

[0008] To address the aforementioned issues, there is an urgent need for a mechanical locking solution that can be triggered instantly upon power failure, requires no continuous power, and maintains constant braking force. This would completely eliminate the safety risks of servo motors during power outages and simultaneously reduce the overall lifecycle cost of the equipment. The electromagnetic lock mechanical locking structure proposed in this invention is designed based on this need. It overcomes the shortcomings of traditional solutions through a rigid mechanical locking mechanism, providing an innovative solution for the safety and economy of servo motor-based motion equipment. Summary of the Invention

[0009] To solve the above problems, this utility model provides a mechanical locking structure for a motor, which adopts the form of an electromagnetic lock. When the power is cut off, the electromagnetic lock instantly pops out to mechanically lock the servo motor, thus preventing instantaneous unloading and the rope from being pulled out when the power is cut off.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] This utility model provides a mechanical locking structure for a motor, including a servo motor body and an electromagnetic lock body. The electromagnetic lock body and the servo motor body are fixedly connected. The top surface of the servo motor body is provided with a locking slot. The electromagnetic lock body is embedded in the locking slot of the servo motor body through a locking tongue.

[0012] Furthermore, a winding reel is provided below the servo motor body.

[0013] Furthermore, a fixed shaft is provided above the servo motor body.

[0014] Beneficial effects:

[0015] As can be seen from the above technical solution, compared with the prior art, the motor mechanical locking structure provided by this utility model adopts the form of an electromagnetic lock. When the power is cut off, the electromagnetic lock instantly pops out to mechanically lock the servo motor, eliminating the situation of instantaneous unloading of force and the rope being pulled out when the power is cut off. Compared with the traditional electromagnetic brake braking method for servo motors, the electromagnetic lock can completely mechanically lock the motor, and the braking force will not gradually weaken over time. The cost is lower and it is conducive to market promotion. Attached Figure Description
