Please refer to Fig. 1-18, the device for achieving multi-axis output from a single power source shown in a preferred embodiment of the present invention includes a single power source 1, an output shaft mechanism, multiple clutch mechanisms 3, a driving mechanism and a driven shaft mechanism.

The power source 1 drives the output shaft mechanism to rotate, and is used to provide power for the output shaft mechanism to rotate. The power source 1 can be an electric motor or an air motor. The power source 1 is provided with a power shaft for driving the output shaft mechanism to rotate synchronously. The number of the power shafts depends on the selected power source 1 , generally, the number of the power shafts can be one or two on opposite end faces. In this embodiment, as shown in FIG. 11 , a first power shaft 6 and a second power shaft 7 are respectively provided on two opposite end surfaces of the power source 1 .

The output shaft mechanism includes at least one output shaft 2 matched with any power shaft. In this embodiment, as shown in FIG. 12 , the output mechanism includes at least one first output shaft 8 matched with the first power shaft 6 and at least one second output shaft matched with the second power shaft 7 Output shaft 9. When there is only one power shaft, the output shaft mechanism includes at least two output shafts 2 matched with the power shaft.

As shown in Figures 12-14, the first power shaft 6 (or the second power shaft 7) drives the first output shaft 8 (or the second output shaft 9) to rotate synchronously through a transmission mechanism 10 or a steering mechanism. Both the transmission mechanism 10 and the steering mechanism are used for power transmission. In addition to power transmission, the steering mechanism can also change the direction of power output, that is, change the axis of the first output shaft 8 (or the second output shaft 9) and the first power shaft 6 (or the second output shaft 9) of the power source 1 The angle between the axes of the two power shafts 7).

The steering mechanism can be a worm gear mechanism 11 or a bevel gear assembly 12 . When the bevel gear assembly 12 is used, power output at any angle can be realized by changing the angle of the bevel gear.

The speed change mechanism 10 or the steering mechanism are commonly used components known in the art, and structures disclosed in the prior art or commercially available products can be used, and details will not be repeated here.

Any clutch mechanism 3 is respectively connected with the output shaft mechanism and the driven shaft mechanism, and is used for power transmission/disconnection transmission between the output shaft 2 and the driven shaft 4 .

The driven shaft mechanism includes a driven shaft 4 that is in one-to-one correspondence with any output shaft 2 .

Since the clutch mechanism 3 is a commonly used component known in the art, the structures disclosed in the prior art or commercially available products can be used, and details will not be repeated here.

And no matter what kind of clutch mechanism is selected, generally speaking, any clutch mechanism 3 all comprises the first fitting 17 and the second fitting 18 that match, and for different clutch mechanisms 3, its matching method is also slightly different, as For the gear type clutch mechanism 16, its matching method is gear meshing, and for the friction clutch mechanism 14, its matching method is the compression of the friction surface, etc. Those skilled in the art can determine its matching according to the selected clutch mechanism 3. ways, therefore, will not repeat them one by one. The first fitting 17 is connected to the output shaft 2 (the first output shaft 8 or the second output shaft 9 ), and the second fitting 18 is connected to the driven shaft 4 . Further, the second fitting 18 is fixedly connected to the driven shaft 4 in a circumferential direction, that is, the second fitting 18 can move axially relative to the driven shaft 4, but cannot move relative to the driven shaft 4. The shaft 4 rotates circumferentially.

The swing rod motor 19 is used to drive the slider 21 to slide relative to the base frame 20 . The sliding member 21 is fixedly connected with the swing rod, and the sliding member 21 slides to drive the swing rod to move. The swing rod includes a connecting rod 22 , a first sub-swing rod 23 and a second sub-swing rod 24 fixedly connected to the connecting rod 22 . The connecting rod 22 is fixedly connected with the sliding member 21 . The end of the first sub-sway bar 23 away from the connecting rod 22 is connected to the first fitting 17 (or the second fitting 18) of a clutch mechanism 3, and the second sub-swing bar 24 is far away from the coupling. One end of the rod 22 is connected with the first fitting 17 (or the second fitting 18) of the other clutch mechanism 3, and the sliding part 21 is driven by the swing motor 19 to slide and then drive the swing to move, thereby Drive the two fittings in any clutch mechanism 3 to cooperate and connect/disconnect each other, that is, control the opening and closing of any clutch mechanism 3, so as to realize the connection and separation between the driven shaft 4 and the corresponding output shaft 2, Finally, the independent operation or synchronous operation of controlling two or more driven shafts 4 is realized.

In addition to the above-mentioned structure, the swing link mechanism can also be other structures capable of opening and closing the clutch mechanism 3. As shown in Figures 2-5, another swing link mechanism includes a swing link motor assembly 27, a rocker arm 28 and pendulum.

The motor assembly 27 is used to provide power, one end of the rocker arm 28 is connected to the motor assembly 27, and the other end is connected to the connecting rod 22, the motor assembly 27 drives the rocker arm 28 to rotate, and then Drive the connecting rod 22 connected with the rocker arm 28 to move, thereby driving the first sub-swing link 23 and the second sub-swing link 24 to move, and finally realize the control of opening and closing of the two clutch mechanisms 3 . When the rocker arm 28 rotates to the left as shown in Fig. 4, it drives the first sub-swing lever 23 on the left side in Fig. The shafts are connected, and at the same time, the second sub-fork 24 on the right side is driven to move so that the clutch mechanism on the right side is connected, that is, the output shaft on the right side is disconnected from the driven shaft, so that only the driven shaft on the left side can be realized. PTO. Similarly, when the rocker arm 28 rotates to the right as shown in FIG. 5 , only the power output of the right driven shaft can be realized. When the rocking arm 28 rotates to the middle position as shown in Figure 3, the first sub-swing bar 23 and the second sub-swing bar 24 are driven to move at the same time so that the clutch mechanisms on the left and right sides are all connected, and the left and right sides can be realized. Driven shaft average power output.

As shown in Figure 9, the clutch mechanism 3 is connected to the corresponding output shaft or driven shaft through an electromagnetic assembly, and the electromagnetic assembly includes a first electromagnet 25 connected to the clutch mechanism 3 and a first electromagnet 25 connected to the output shaft. The second magnet 26 connected to the shaft or the driven shaft, and the controller (not shown) that controls the attraction and repulsion between the first electromagnet 25 and the second magnet 26. The controller controls the magnetism of the first electromagnet 25 to be the same as or different from that of the second magnet 26, so that the first electromagnet 25 and the second magnet 26 repel or attract each other to realize the output shaft 2 and the second magnet 26. The driven shafts 4 are disconnected or connected so that the power can be transmitted from the power source 1 to the driven shaft 4 or the power cannot be transmitted to the driven shaft 4 . It can be understood that the second magnet 26 can also be an electromagnet, and the controller controls and adjusts the magnetism of the second magnet 26 . Figure 18 is another embodiment in which the clutch mechanism 3 is connected to the corresponding output shaft or driven shaft through an electromagnetic assembly. The only difference is that the second magnet 26 is not connected to the output shaft or driven shaft. Instead, it is fixedly installed at a position corresponding to the first electromagnet 25, and other structures and control principles are the same as those shown in FIG. 9 .
