The strip-shaped accommodating cavity 101 can provide a smooth flowing space for the filling liquid 21, reduce the resistance of the filling liquid 21 in the flowing process, and improve the force application effect when the filling liquid 21 impacts the impact surface 1011.

Referring to fig. 2, the filling mechanism 20 may further include a filling solid 22, and the filling solid 22 can move along with the flow of the filling liquid 21. The filler solid 22 may be a metallic or magnetic member, such as steel grit. In this case, the filling solid bodies 22 may be spheres, and the size of each filling solid body 22 may be the same or different from that of at least two first filling members 221. The solid filler 22 may also be an adhesive, an elastically or plastically deformable object. The filling solid 22 may be insoluble in liquid or soluble in liquid under certain conditions, for example, when the acceleration is greater than or less than a specific value, the filling solid 22 may be suspended in the liquid or may be a heavy object with a density greater than that of the liquid. When the filling solid 22 is a heavy object with a density greater than that of the fluid, the setting of the filling solid 22 can increase the impact feeling on the basis of the fluidity, so that the user can obtain instant mechanical feedback and sound feedback, and the user experience is improved. Wherein, filling liquid 21 can play the cushioning effect to filling solid 22, has reduced filling solid 22 to the vibrations influence of dumbbell body 10.

In the embodiment, referring to fig. 2, the accommodating cavity 101 is a square body, the impact surface 1011 can be a first side wall, the cavity wall of the accommodating cavity 101 further includes a second side wall 1012, a third side wall 1013 opposite to the impact surface 1011, and a fourth side wall 1014 opposite to the second side wall 1012, that is, the second side wall 1012, the third side wall 1013, and the fourth side wall 1014 of the impact surface 1011 enclose a quadrangle, and when the user swings the sprint dumbbell, the filling liquid 21 can impact the impact surface 1011, the second side wall 1012, the third side wall 1013, or the fourth side wall 1014 according to the change of the motion acceleration. Optionally, the second side wall 1012, the third side wall 1013 and the fourth side wall 1014 of the impact surface 1011 are formed in a square shape, such as a rectangle or a square, so as to uniformly apply force to the opposite walls of the receiving cavity 101. In other embodiments, the accommodating cavity 101 may also be oval, polygonal, irregular, etc.

Referring to fig. 2, preferably, the filling solid 22 may include at least one first filling member 221 and at least one second filling member 222, and both the first filling member 221 and the second filling member 222 may be metal members or magnetic members, such as steel grit. The first filling members 221 may be spheres, and the sizes of the first filling members 221 may be the same or the sizes of at least two first filling members 221 may be different. In other embodiments, the first filling member 221 and the second filling member 222 may also be an adhesive member, an object that can be elastically or plastically deformed. When the filling liquid 21 hits the impact surface 1011, the first filling member 221 and the second filling member 222 can move relatively by inertia. In this embodiment, the first filling member 221 and the second filling member 222 have a suction state in which they are sucked together. When the first filling member 221 and the second filling member 222 are in an attraction state, the first filling member 221 and the second filling member 222 are combined into a whole, but because the first filling member 221 and the second filling member 222 are combined in an independent and dispersed structure, when the filling solid 22 impacts the impact surface 1011, a relative motion can be generated under the action of inertia force, and the filling solid 22 is deformed in a certain way as seen from the whole filling solid 22. At this moment, the first filling pieces 221 can impact the impact surface 1011 at different time points, so that the impact force has certain hierarchy, a user can feel stress variation, the user experience is improved, and meanwhile, the stress variation can buffer the impact force, and the risk of muscle strain of the user is reduced. The first filling member 221 and the second filling member 222 may be attracted together by magnetic force, electric force, or other attractive force.

In this embodiment, the first filling member 221 and the second filling member 222 are magnetically attracted, and the plurality of first filling members 221 are magnetically attracted to the second filling member 222. At least one of the first filling member 221 and the second filling member 222 is a magnetic member, and the other is a magnetic member or a metal.

The first filling member 221 and the second filling member 222 have a magnetic attraction state, and the first filling member 221 and the second filling member 222 can be in the attraction state when the impact force applied to the filling solid 22 striking the impact surface 1011 is smaller than the magnetic attraction force between the first filling member 221 and the second filling member 222. In this embodiment, the first filling members 221 are metal balls, the second filling members 222 are permanent magnets, and the plurality of first filling members 221 can be attracted to the second filling members 222 under the magnetic attraction of the second filling members 222. It can be understood that the impact force generated by the solid filler 22 when the absolute value of the acceleration of the dumbbell body 10 is smaller than the preset value can be smaller than the magnetic attraction force between the first filler 221 and the second filler 222, that is, when the speed change of the dumbbell body 10 is not large, the first filler 221 and the second filler 222 can still be in the attraction state even if being impacted, and the solid filler 22 may only be deformed integrally or not deformed.

The first filling member 221 and the second filling member 222 also have a separated state in which they are separated from each other, and the first filling member 221 and the second filling member 222 can be in the separated state when the impact force applied to the filled solid 22 when the filled solid strikes the impact surface 1011 is greater than the magnetic attraction force between the first filling member 221 and the second filling member 222. It can be understood that the impact force generated by the solid filler 22 when the absolute value of the acceleration of the dumbbell body 10 is greater than the preset value can be greater than the magnetic attraction force between the first filler 221 and the second filler 222, that is, when the speed of the dumbbell body 10 changes rapidly, the first filler 221 and the second filler 222 can be separated when being impacted, and the separation can be separation from the magnetic attraction force or separation from the magnetic attraction force. The preset value is related to the magnetic attraction between the first filling piece 221 and the second filling piece 222, the adjustment of the preset value can be realized by replacing the second filling piece 222 with different magnetic attraction or the first filling piece 221 with different gravity, and the user can replace the filling solid 22 according to different training requirements. However, due to the hydraulic pressure of the filling liquid 21, compared with the sprint dumbbell without the filling liquid 21 and only the filling solid 22, the preset value required to be reached by the filling solid 22 to obtain the acceleration of the dumbbell body 10 in the separated state is larger, and therefore, in the present embodiment, the filling solid 22 can provide stronger instant force feedback and impact feeling.

The solid filler 22 is capable of striking the striking face 1011 when the dumbbell body 10 moves along the swing axis and striking the second side wall 1012 when moving along the impact axis, that is, the line between the striking face 1011 and the third side wall 1013 is parallel to the swing axis and the line between the second side wall 1012 and the fourth side wall 1014 is parallel to the impact axis. The first filling member 221 and the second filling member 222 can be in an attraction state when the impact force received by the filling solid 22 when the filling solid 22 impacts the second sidewall 1012 is smaller than the magnetic attraction force between the first filling member 221 and the second filling member 222, and are in a separation state when the impact force received by the filling solid 22 when the filling solid 22 impacts the second sidewall 1012 is larger than the magnetic attraction force between the first filling member 221 and the second filling member 222, and the swing shaft and the impact shaft are arranged at an included angle. The principle of the impact of the filling solid 22 against the second side wall 1012 is the same as that of the impact surface 1011 and is not described in detail here.

In the present embodiment, the extending direction of the arm may be taken as the impact axis, the direction perpendicular to the extending direction of the arm may be taken as the swing axis, the swing axis may be taken as the up-down direction, and the impact axis may be taken as the front-rear direction.

When the user swings the dumbbell body 10 in the up-down direction, the filling liquid 21 and the filling solid 22 can both hit the impact surface 1011 or the third side wall 1013, taking the impact surface 1011 as an example, when the user swings faster, the absolute value of the acceleration is larger, when the absolute value of the acceleration is larger than the preset value, the impact force of the filling solid 22 on the impact surface 1011 can be larger than the magnetic attraction force between the first filling piece 221 and the second filling piece 222, the first filling piece 221 and the second filling piece 222 can be switched to be in a separation state, that is, the filling solid 22 is broken up, the plurality of first filling members 221 are allowed to strike the impact surface 1011 at different points of time, and due to the magnetic attraction between the first filling members 221 and the second filling members 222, so that the distance intervals among the plurality of first packing members 221 are small even in the separated state of the packing solid 22, and the impact has continuity, thereby allowing the user to obtain a better fluid force experience. The exercise mode can simulate the motion process of the rope for getting rid of the station without preparing a field and the rope, the exercise can be carried out at home, the use is convenient, and the filling liquid 21 can be replaced according to different training requirements. This exercise pattern can increase muscle recruitment and enhance the stability of the deep muscles by using fluidity.

When a user punches a forward by holding the dumbbell body 10, taking the second side wall 1012 in front of the fourth side wall 1014 as an example, the user stops moving the dumbbell body 10 temporarily after punching, the filling liquid 21 and the filling solid 22 can both impact the second side wall 1012, because the speed of the user when punching is slow, the speed change of the dumbbell body 10 when stopping moving is not large, that is, the absolute value of the acceleration is also small, if the absolute value is smaller than the preset value, the impact force of the filling solid 22 on the second side wall 1012 can be made smaller than the magnetic attraction force between the first filling part 221 and the second filling part 222, the first filling part 221 and the second filling part 222 can be always in an attraction state, that is, the first filling part 221 is always a whole, when the filling liquid 21 impacts the second side wall 1012, the impact force is short, rapid and violent, so that the user can obtain the force experience of hitting a target object, and well simulate the force process of punching, meanwhile, the impact sound of the filling solid 22 on the dumbbell body 10 can provide sound feedback for a user, and user experience is improved. The filling liquid 21 now acts as a buffer for the filling solid 22.

Referring to fig. 1 and 2, in particular, the dumbbell body 10 has a hand-held portion 11 and a supporting portion 12 connected to the hand-held portion 11, the user can exercise by holding the hand-held portion 11, and the supporting portion 12 can be provided with a supporting surface, so that the user can stably support on a supporting surface, for example, the supporting surface can support on the ground to perform push-up. The user can each hold a sprint dumbbell with both hands when taking exercise, and preferably, supporting part 12 has magnetism, can be with two supporting part 12 actuation relatively if taking exercise and finish to accomodate. The two punching dumbbells can be symmetrically arranged, the supporting part 12 of one punching dumbbell is provided with magnetism, and the other punching dumbbell is made of metal materials, or the supporting parts 12 of the two punching dumbbells are provided with magnetism. In the embodiment, the handle 11 is in a shape of a stick and extends along the swing axis, and the handle 11 further has an anti-slip surface for a user to hold, and the shape of the handle meets the ergonomic requirement of hand holding. The accommodating cavity 101 in the middle of the three accommodating cavities 101 may be located in the handheld portion 11.

The accommodating cavities 101 may be provided in plurality, and each accommodating cavity 101 is filled with a filling mechanism 20. Set up the effect that a plurality of holding chambeies 101 can strengthen mobility and striking to satisfy the different demands of user, promote user experience. In the present embodiment, referring to fig. 2, the dumbbell body 10 is provided with three accommodating cavities 101, and the accommodating cavities 101 are arranged at intervals. Preferably, at least two of the accommodating cavities 101 have different extending directions, so as to meet the requirement of mobility of a user during swing training in different directions.

Optionally, three accommodating chambers 101 are sequentially arranged along the swing axis, wherein the accommodating chamber 101 in the middle extends along the swing axis, and the two accommodating chambers 101 respectively located at the two ends extend perpendicular to the swing axis. That is to say. The distance between the striking surface 1011 of the receiving chamber 101 and the third sidewall 1013 is smaller at both ends than between the second sidewall 1012 and the fourth sidewall 1014, and the distance between the striking surface 1011 of the receiving chamber 101 and the third sidewall 1013 is larger at the middle than between the second sidewall 1012 and the fourth sidewall 1014.

If the user swings up and down, the up-down distance of the two accommodating cavities 101 is smaller than the front-back distance of the two accommodating cavities, so that when the user swings the dumbbell body 10 up and down, the filling liquid 21 and the filling solid 22 in the accommodating cavities 101 move up and down, the filling liquid 21 is easily shaken and scattered in a short distance, and when the impact force of the filling liquid 21 is larger than the magnetic attraction force between the first filling piece 221 and the second filling piece 222, the scattered filling solid 22 is not enough to be attracted into a whole again in a short distance, namely, not enough to be switched into an attraction state again, and the flowing experience in the subsequent impact process is enhanced. When a user holds the dumbbell body 10 to punch a fist, the filling mechanism 20 in the accommodating cavity 101 moves forwards, when the impact force of the filling solid 22 is smaller than the magnetic attraction force between the first filling piece 221 and the second filling piece 222, the filling solid 22 can be in an attraction state in the movement process in the accommodating cavity 101, so that the second side wall 1012 is integrally impacted, the longer front-back distance also provides enough flying distance for the filling liquid 21 in the accommodating cavity 101, the filling liquid 21 can integrally apply force to the second side wall 1012, so that the user obtains larger and stronger stress feedback and sound feedback, and the user instant experience is improved. The distance is less than upper and lower distance around the holding chamber 101 in the middle of, is the same with the principle of above-mentioned holding chamber 101, nevertheless can strengthen the atress feedback when rocking the training to promote the striking and experience when going out the fist.
