TECHNICAL FIELD

[0002] Shaft transmission technology is widely used, for example, a window is installed on a window frame through a rotating shaft, for example, a car gull wing door or trunk door is installed on a car body through a rotating shaft, for example, in a photovoltaic tracking device, a photovoltaic panel is connected with a fixed support through a rotating shaft, and for example, a bicycle wheel is connected with a frame.
[0003] In such applications, the rotating shaft is usually horizontally arranged or arranged non-perpendicularly to the ground; at this time, the load driven by the rotating shaft, such as a window, a door, a photovoltaic panel, etc., is arranged offset, so that the center of gravity of the load driven by the rotating shaft cannot coincide with the central axis of the rotating shaft, and thus, in the rotating process, the center of gravity of the load driven by the rotating shaft also rotates around the rotating shaft, and thus, when the rotating shaft drives the load to move, the following two situations may occur: first, the center of gravity moves from a high position to a low position, at this time, the torque output by the power source (such as a motor) for driving the load to move through the rotating shaft is usually kept in a situation where the load does not rotate freely, that is, to overcome the effect of gravity; second, the center of gravity moves from a low position to a high position, at this time, the torque output by the power source needs to overcome the effect of gravity and also needs to be able to drive the load to move.
[0004] In the above two situations, when the center of gravity of the load and the central axis of the rotating shaft are located at the same horizontal position, the effect of gravity of the load is the largest.

[0054] The first type, each group of power-assisted units 2 includes one elastic member 23, so the number of elastic members 23 is consistent with the number of adapter parts 221, and therefore the number of first through holes 12 and second through holes 13 arranged on the profile is equal. At this time, the first through holes 12 and the second through holes 13 are arranged in turn and alternately along the axial direction of the main body 11.
[0055] The second type, as shown in Figures 1 to 5 each group of power-assisted units 2 includes two symmetrically arranged elastic members 23, so the number of first through holes 12 is twice the number of second through holes 13, and therefore two first through holes 12 and one second through hole 13 are arranged in turn and arrayed along the axial direction of the main body 11.

[0057] As shown in Figures 1 to 3 the second aspect of the present embodiment discloses a fixing member 1, which comprises:
[0058] a shell made of the profile as described above;
[0059] and further comprises a protective member 14 for shielding the first through hole 12 and the second through hole 13, the protective member 14 being connected to the outer circumferential surface of the main body 11.
[0060] It should be noted that in the present embodiment, the shield 14 is used to shield the first through hole 12 and the second through hole 13, and isolate the adapter, the elastic member 23 in the force assisting unit 2 from contacting the outside. On the basis of meeting the function of the shield 14, as shown in Figure 3 the cross section of the shield 14 is C-shaped, the shield 14 extends along the axial direction of the main body 11, and the shield 14 is provided with a connecting portion 141 on both sides, and the shield 14 is connected to the outer circumferential surface of the main body 11 through the connecting portion 141.
[0061] As shown in Figures 1 to 5 the third aspect of the present embodiment discloses a force assisting device, which comprises the fixing member 1 as described above;
[0062] Further comprising at least one set of force assisting unit 2, the force assisting unit 2 is arranged in the barrel cavity of the fixing member 1, and a plurality of sets of force assisting units 2 are arranged coaxially, and the force assisting unit 2 comprises:
[0063] a driving member 21, the main body 11 is provided with a through hole 211 connected to an external load, and the driving member 21 is provided with an avoiding slot;
[0064] a retainer 22, which is rotationally connected to the driving member 21 in a coaxial manner, and the retainer 22 is hingedly connected with an adapter 221, and the adapter 221 is provided with a first combining portion 2211 matched with the avoiding slot and a second combining portion 2212 matched with the first through hole 12;
[0065] an elastic member 23, one end of the elastic member 23 is connected to the second through hole 13, and the other end is connected to the driving member 21.
[0066] It should be noted that in the present embodiment, in order to make the adapter 221 more smoothly separate from the first through hole 12 in the embedded state of the first through hole 12, as shown in Figure 3 and Figure 4 the plane formed between the axis of the adapter 221 and the axis of the first combining portion 2211 is a first plane, and the retaining portion 121 is located at one end of the first plane away from the axis of the retainer 22.
[0067] The advantages of the present embodiment are: improving the efficiency of profile processing suitable for force assisting devices, and making the force assisting device run more smoothly.
[0068] Firstly, the main body 11 of the profile is in a cylindrical shape. The cylindrical main body 11 is easy to process, and the cylinder cavity can directly accommodate the power assisting unit 2 in the power assisting device. The first through hole 12 is arranged on the cylinder wall of the main body 11 to cooperate with the adapter 221 of the power assisting unit 2. The second through hole 13 is arranged on the cylinder wall of the main body 11 to hang the elastic member 23 in the power assisting unit 2. Therefore, the profile is used as the shell of the power assisting device. The elastic member 23 and the adapter 221 can be reliably connected to ensure the reliability of the power assisting device. The processing method is simple, the processing efficiency is high, and the processing cost is low.
[0069] Secondly, the protective member 14 is connected to the outside of the main body 11 by the connecting part 141. The second through hole 13 of the first through hole 12 is shielded by the protective member 14. The external dust cannot enter the inside of the power assisting device to reduce the efficiency of the power assisting device. The external collision and interference on the adapter 221 and one end of the elastic member 23 cannot affect the working state of the power assisting device. The potential hidden danger caused by the damage of the elastic member 23 or the adapter 221 and directly splashing out of the corresponding through hole to the surrounding environment can be prevented. Therefore, the smoothness of the power assisting device with the protective member 14 is ensured, and the safety of the power assisting device with the protective member 14 is improved.
[0070] Thirdly, the plane formed between the axis of the adapter 221 and the axis of the first connecting part 2211 is the first plane. The retaining part 121 of the present embodiment is located at one end of the first plane away from the retainer 22. The retaining part 121 and the inner wall of the main body 11 are provided with a chamfer. Therefore, when the retainer 22 drives the adapter 221 to rotate, the first connecting part 2211 can be separated from the first through hole 12, and the power assisting device runs more smoothly.
