[0034] Example 1

[0035] Please refer to Figures 1 and 2. Embodiment 1 of this utility model is as follows: A smart dumbbell device includes a bell plate 1 and a body 2. The bell plate 1 is provided with a magnet 3 for forming a magnetic field. The body 2 is provided with an electrically connected main control board and a Hall sensor 4. The Hall sensor 4 is used to detect the magnetic field.

[0036] In some embodiments, the main body 2 is provided with a display screen electrically connected to the main control board. The display screen can display the current weight of the smart dumbbell device based on the detection result of the Hall sensor 4, so that the user can directly know the current weight of the smart dumbbell device.

[0037] Optionally, the main control board is equipped with a wireless communication module, which may be a Bluetooth data transmission module, etc. The smart dumbbell device can wirelessly connect with the user's mobile terminal through the wireless communication module, so that the user can know the weight of the smart dumbbell device by checking the mobile terminal device; the mobile terminal includes, but is not limited to, mobile phones, tablets, smartwatches, VR glasses, etc.

[0038] In addition, in specific products, the main body 2 can also be equipped with indicator lights that are electrically connected to the main control board to let users know the weight of the current smart dumbbell device. For example, the indicator lights emit different colors of light to indicate the weight of the current smart dumbbell device, or the indicator lights flash different numbers of times to indicate the weight of the current smart dumbbell device, or the indicator lights are lit up in different numbers to indicate the weight of the current smart dumbbell device, etc.

[0039] Of course, in specific products, the main body 2 can also be equipped with an electroacoustic converter electrically connected to the main control board to let the user know the weight of the current smart dumbbell device. Specifically, when the electroacoustic converter is a speaker, the speaker can directly announce the weight of the current smart dumbbell device; when the electroacoustic converter is a buzzer, the buzzer can indicate the weight of the current smart dumbbell device through different rhythms.

[0040] To enable the Hall sensor 4 to detect external magnetic fields more sensitively, the Hall sensor 4 is positioned near the end of the body 2.

[0041] In this embodiment, the end face of the body 2 is provided with a blind hole 5, the bell 1 has a protrusion 11 that cooperates with the blind hole 5, the magnet 3 is disposed on the protrusion 11, preferably the Hall sensor 4 is disposed corresponding to the central area of ​​the bottom surface of the blind hole 5, and the magnet 3 is disposed corresponding to the central area of ​​the end face of the protrusion 11. When the bell 1 is installed, the Hall sensor 4 and the magnet 3 are positioned opposite each other, so that the Hall sensor 4 can better detect the magnetic field generated by the magnet 3.

[0042] The blind hole 5 is provided with a locking structure 61, and the protrusion 11 is provided with a mating structure 62 that cooperates with the locking structure 61. The locking structure 61 includes, but is not limited to, at least one of threads and snaps.

[0043] In one or more embodiments, the number of bells 1 is multiple, and at least one of the bells 1 is also provided with a blind hole 5. The blind hole 5 on the bell 1 is used to cooperate with the protrusion 11 on another bell 1. The protrusion 11 and the blind hole 5 are respectively located on opposite sides of the bell 1.

[0044] Preferably, the magnetic poles of the magnets 3 in each of the bells 1 are oriented in the same direction. When multiple bells 1 are installed at one end of the body 2, the magnets 3 in the multiple bells 1 can form a superimposed magnetic field. The magnetic field strength of the superimposed magnetic field is greater than the magnetic field strength generated by a single magnet 3. Therefore, based on the detection result of the Hall sensor 4, the number of bells 1 currently installed at one end of the body 2 can be effectively distinguished.

[0045] Optionally, the intelligent dumbbell device also includes an end cap 7 for sealing the blind hole 5 on the bell plate 1, and it is readily understood that the end cap 7 is also provided with the mating structure 62.

[0046] As an alternative implementation, at least one of the bell plates 1 has no blind hole 5 on the side away from the protrusion 11. This bell plate 1 without blind hole 5 can be used as the outermost bell plate 1 of the smart dumbbell device. In this case, there is no need to set the end cap 7.

[0047] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
