Other embodiments may be other items such as a wheel carrier or a hospital bed, but are not limited thereto.

The at least one wheel body 4 is pivotally disposed on the wheel base 3 along an axial direction 5. In the embodiment, the number of the at least one wheel body 4 is two.

The GPS module 6 is disposed on the body 1 and includes a GPS chip 61. The GPS chip 61 sends a GPS signal to locate and track the smart caster to know the position of the pusher, and because of the GPS mode. The group 6 is disposed on the body 1 and can be kept at a distance from the detecting instrument to avoid mutual interference.

Specifically, the pin 2 is pivotally connected to the wheel base 3 along the axial direction 5 to facilitate the turning of the pusher bed, and the GPS module 6 is disposed on the wheel base 3.

In the embodiment, the GPS module 6 further includes a power storage unit 62. The power storage unit 62 is electrically connected to the GPS chip 61 to provide power to the GPS chip 61 to prevent the GPS chip 61 from being invalid. In this embodiment, the GPS module 61 is disabled. The power storage unit 62 is a capacitor to provide a small amount of power to the GPS chip 61. In other embodiments, the power storage unit 62 can be a battery having a large storage capacity, and the GPS chip 61 can also be used. The power storage unit 62 is disposed in a casing, and the casing is disposed on the body 1 to protect the GPS module 6.

Further, the smart caster further includes a power generating component 7 electrically connected to the GPS module 6. The power generating component 7 is disposed on the body 1 and is rotatably coupled to one of the wheel bodies 4 to enable the When the wheel body 4 rotates, the power generating component 7 is driven to generate electricity. Therefore, when the pushing bed is pushed, the power generating component 7 is driven by the wheel body 4 and generates electricity to provide power of the GPS module 6, even if the GPS module 6 When the power storage unit 62 is not provided, when the pusher bed moves, the wheel body 4 is rotated, and the power generating component 7 is driven by the wheel body 4 to generate electricity, and the power generating component 7 can generate power. The GPS module 61 can transmit the GPS signal to transmit the GPS signal, so as to know the moving path and the instantaneous position of the push bed, so the GPS module 6 does not need to be additionally charged via an external power source. Steps can effectively achieve the purpose of tracking and managing the pusher.

In detail, the wheel body 4 is provided with a first gear 41. The power generating assembly 7 is provided with a rotor 71 and a second gear 72. The first gear 41 meshes with the second gear 72. In the embodiment, the wheel body 4 is provided with a ring protrusion 42 along the axial direction 5, and the ring protrusion 42 is radially provided with at least one first card portion 421. The first gear 41 is annular and sleeved on the ring gear 42. The first gear 41 is provided with at least one second card portion 411 which is respectively engaged with the at least one first card portion 421, so that the first gear 41 can be rotated together with the wheel body 4. In the embodiment, the ring gear 42 and the first gear 41 are respectively provided with a plurality of the first card portion 421 and the plurality of second card portions 411, and the first gear 41 can be driven when the first gear 41 rotates. The second gear 72 and the rotor 71 rotate, and the power generating unit 7 can generate electricity.

It is to be noted that, in this embodiment, the power storage unit 62 is electrically connected to the GPS chip 61. The GPS chip 61 and the power storage unit 62 are disposed on the substrate 31. The power generating component 7 is electrically connected to the power storage unit. 62. Therefore, when the power generation unit 7 generates electric power, power is transmitted to the electric storage unit 62, and the electric storage unit 62 can transmit a small amount of electric power to the GPS wafer 61. Therefore, when the pusher bed is moved, the power storage unit 62 transmits a small amount of power to the GPS chip 61 to cause the GPS chip 61 to emit a GPS signal to track and record the position of the push bed, when the push bed stops moving, The power generating component 7 does not continue to generate power. After a period of time, the power of the power storage unit 62 is used, and the GPS chip 61 stops sending the GPS signal, and the GPS chip 61 will re-issue the next time the pusher moves. The GPS signal can effectively avoid the interference of the GPS signal, and at the same time save power and avoid excessive use of the GPS chip 61.

It is to be noted that the wheel base 3 includes a base plate 31 and two shell members 32. The two shell members 32 are disposed on the two sides of the substrate 31 along the axial direction 5, and the base plate 31 is radially provided with a recessed portion 311. The power generating assembly 7 is provided in the recessed portion 311. The wheel base 3 further includes an axle 33 that is disposed along the axial direction 5 of the base plate 31 and the two shell members 32. The two wheel bodies 4 are separated from the side of the two shell members 32 and the axle 33 respectively. Grouped together.

In addition, in this embodiment, one of the wheel bodies 4 is provided with a concave ring groove 43. The wheel base 3 is provided with two brake blocks 34 slidable along the length of the pin 2, and the two blocks 34 can be selected. Sexually interferes against the top of the concave ring groove 43 to achieve the braking effect, and avoids any rotation of the wheel body 4 to cause the sliding bed to slide freely.

In summary, the smart caster of the present invention can transmit and locate a smart caster by using the GPS chip to locate and track the smart caster to know the position of the pusher, and since the GPS module is disposed on the body, The test instrument is kept at a distance to avoid mutual interference.

And the power generating component is disposed on the body and is rotatably connected to one of the wheel bodies to drive the power generating component to generate electricity when the wheel body rotates, and the power generating component is electrically connected to the GPS module, so when the pushing bed is pushed When the power generation component is driven by the wheel body and generates electricity to provide power of the GPS module, the step of charging via an external power source is not required, and the tracking management effect can be effectively achieved.
