Description
Technical Field
[0001] The utility model belongs to the technical field of sports equipment, and in particular relates to an upper limb explosive force training device. Background Art
[0002] Upper limb power refers to the ability to rapidly exert maximum force in a short period of time, which is essential for athletes' performance in a variety of sports, such as weightlifting, swimming, basketball, and boxing. In addition, upper limb strength and power training have significant effects on improving athletic performance, enhancing functional abilities in daily life, and preventing injuries. Traditional upper limb strength training methods usually rely on free weights, dumbbells, and barbells. However, these training methods often make it difficult to accurately control the intensity of training, and there may be safety risks in high-intensity explosive power training.
[0003] Existing training devices often lack special designs for upper limb explosive power training and cannot effectively simulate the rapid force output in actual sports. Document number CN109925677A "An intelligent upper limb muscle strength super isometric training device" provides a training device for rapid stretching and shortening cycles for the forearm. The invention can adjust the size of the resistance load according to the user's situation, which improves the comfort of the trainer, but can only perform single-joint exercises for the biceps and triceps, and the muscle groups involved in the exercise are relatively small, and it is impossible to provide feedback on training parameters in real time. Traditional upper limb explosive power training is mainly based on the end release type of equipment such as medicine balls, which cannot achieve fine adjustment of weight and detection and feedback of explosive power related indicators. Moreover, medicine ball upper limb explosive power training is a one-time explosive power exercise, and it is impossible to perform multiple times of continuous explosive power training for specific special needs. Traditional continuous upper limb explosive power training is mainly carried out through the body's own weight or equipment such as elastic bands, such as continuous pull-ups, elastic band rapid arm flexion and extension, etc. These training methods also have pain points such as the inability to finely adjust the load and the detection of explosive power related data.

[0034] like Figure 1 and Figure 3 As shown, the present embodiment provides an upper limb explosive power training device, comprising a mounting seat 1, a rope collector 2 and a push rod 3. The mounting seat 1 is hollow inside and is horizontally arranged along the front-to-back direction.

The rope collector 2 is used to apply a backward swinging force to the push rod 3, so that the user can stand behind the mounting seat and push the push rod forward with both hands to overcome the resistance of the rope collector to push it out, thereby exercising the explosive power of the user's upper limbs.
[0035] like Figure 4As shown, in the above technical solution, both sides of the front end of the mounting seat 1 are gradually narrowed to form a cone tip at the front end of the mounting seat 1, and the lower end of the push rod 3 is swingably connected to the cone tip at the front end of the mounting seat 1, so that the structure of the entire mounting seat is compact and its stability is good.
[0036] The bottom of the mounting seat in this embodiment is a flat surface, and a hinge seat 15 is arranged at the upper end at the cone tip. The lower end of the push rod is swingably connected to the hinge seat 15. The push rod can swing back and forth with the hinge seat as a fulcrum. The hinge seat is U-shaped, and its structure belongs to the prior art and will not be described here.
[0037] like Figure 2 As shown, the upper end of the push rod 3 in the above technical solution is provided with a handle bar 31 along the left-right direction, and the middle part of the handle bar 31 is connected to the push rod 3 in a "T" shape, so that the two ends of the handle bar can be held with both hands and pushed forward. Preferably, the two ends of the handle bar 31 are bent downward, so that the vertical sections at the two ends of the handle end or the horizontal section in the middle can be held with both hands and pushed forward. Further, the upper end of the push rod 3 and the handle bar 31 in the above technical solution are provided with an anti-slip cover 32, so that the protection effect of the push rod and the handle bar is good, and the protective cover 32 can be a silicone cover.
[0038] In the above technical solution, a limit rod 33 is provided at the front lower end of the push rod 3, and the angle formed by the limit rod 33 and the push rod 3 in the vertical plane corresponding to the front and rear directions is 30-120 degrees, so that the forward swing angle of the push rod can be limited, that is, the maximum swing range of the push rod forward is when the front end of the limit rod is against the ground (such as Figure 6 Preferably, the limiting rod is vertically connected to the lower end of the push rod.
[0039] In the above technical solution, rollers 12 are respectively arranged on both sides of the rear lower end of the mounting seat 1, and the end of the limiting rod 33 away from the push rod 3 is bent upward into a ring shape, so that a person can use the limiting rod as a handle to lift the mounting seat off the ground, and then drag the mounting seat to move to carry the upper limb explosive power training device.
[0040] like Figure 4 and Figure 5As shown, the rope retractor 2 in the above technical solution also includes a resistance motor 22, a winding shaft 23 and an encoder 24, and the resistance motor 22, the winding shaft 23 and the encoder 24 are all arranged at the inner rear end of the mounting seat 1, and the winding shaft 23 is horizontally arranged in the left and right directions, and its two ends are rotatably connected to the mounting seat 1 through bearing seats 25, the resistance motor 22 is transmission-connected to one end of the winding shaft 23, the rotating end of the encoder 24 is connected to the other end of the winding shaft 23, one end of the rope 21 is connected and fixed to the middle part of the winding shaft 23, and the other end of the rope 21 is an unwinding end, and its structure is simple, and the resistance motor can drive the winding shaft to rotate to reel in the rope, and the resistance motor can also rotate in the opposite direction and provide resistance under the traction of the rope.
[0041] In the above technical solution, baffles 231 are arranged at intervals in the middle of the winding shaft 23 along its length direction, and the two baffles 231 are located between the two bearing seats 25. The two baffles 231 are coaxially connected to the winding shaft 23, and the structure is simple. In this way, the rope can be gathered in the middle of the winding shaft by the two baffles.
[0042] The rope collector 2 in the above technical solution also includes a controller 26 and a human-computer interaction module 27. The controller 26 is arranged in the mounting seat 1, and the human-computer interaction module 27 is arranged at the rear upper end of the mounting seat 1.

[0043] The human-computer interaction module in this embodiment may include a touch screen and buttons or may be directly replaced by a touch screen.
[0044] like Figure 7 As shown, in this embodiment, a buffer pad is set in the middle of the upper end of the slope corresponding to the area directly behind the push rod. The buffer pad can be a foam pad. When the push rod swings backward to the maximum limit, it can be supported on the foam pad.
[0045] In this embodiment, when the push rod swings forward, it will pull the rope to unwind, and the resistance motor will provide unwinding resistance (i.e., tend to increase the unwinding resistance of the reel shaft), and when the support rod stops swinging forward, the resistance motor can stop for 2-5 seconds, and then the resistance motor drives the reel shaft to rotate to reel the rope, and the push rod is supported on the buffer pad. The resistance of the resistance motor during unwinding and the speed during rewinding in this embodiment can be adjusted.
[0046] When in use, the upper limb explosive power training device described in this embodiment can roughly set the resistance size during unwinding (the resistance size is set when the user pushes the push rod forward with maximum force and swings it forward to stop, and the limit rod is close to the ground but not in contact with the ground) and the rotation speed during retraction according to the explosive power of the user's upper limbs. Then the user pushes the push rod forward with maximum force using both hands (pushing the handle bar when using both hands) or one hand (pushing the upper end of the push rod when using one hand) until the push rod swings back to its reset position. In this process, the resistance size during unwinding, the rotation speed during retraction, the peak power and the average power of the resistance motor can be known through the human-computer interaction module (these parameters are known by the encoder). Of course, the push rod can be pushed forward once or multiple times in succession.
[0047] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form.
