In the embodiment, the constant force mechanism with adjustable balance force is arranged between the back plate 1 and the backpack connecting plate 2, the spring group 6 is pulled by the first flexible rope 9, and the direction of the flexible rope 9 is changed under the action of the first guide wheel group 5 and the second guide wheel group 7. The first flexible rope 9 mainly has the function of pulling the spring group 6 to move up and down by the relative displacement generated between the back plate 1 and the backpack connecting plate 2 in the movement process of a human body after the balance load is regulated. The position of the sliding block 4 can be changed by adjusting the rotating nut on the screw pair 3 by changing the height of the sliding block 4 and further changing the weight of the balance object.

Optionally, as shown in fig. 4 and fig. 5, the backpack connection plate 2 is slidably disposed on the back plate 1 through a sliding rail assembly disposed on the other side surface of the back plate 1, where the sliding rail assembly includes a pulley seat 18, a vertical sliding rail 19, and three pulleys 20; the pulley seat 18 is fixed on the backboard 1, the backpack connecting plate 2 is installed on the vertical sliding rail 19, the vertical sliding rail 19 is clamped and slid by three pulleys 20 installed on the pulley seat 18, the peripheral side surface of one pulley 20 is contacted with the end surface of the vertical sliding rail 19, and the peripheral side surfaces of the other two pulleys 20 are contacted with the front side surface and the rear side surface of the vertical sliding rail 19. Further, the vertical slide rail 19 is integrally formed with the horizontal slide rail 11.
Further, as shown in fig. 4, the V-shaped guide wheel 15 rolls on the V-shaped horizontal sliding rail 11 to realize the swing of the swing rod 8, so as to drive the backpack connecting plate 2 to move up and down, the backpack connecting plate 2 clamps the vertical sliding rail 19 through the three pulleys 20, so that the vertical movement of the backboard 1 is realized, the positioning is accurate, the friction force is reduced, the movement precision is greatly improved, two groups of spring groups 6 (spiral tension springs) with larger rigidity coefficients are respectively arranged on two sides of the other side surface of the backboard 1, the spring protection cover 10 is arranged on the outer side of the spring groups 6, and the spring groups 6 are ensured to be always kept in a vertical state in the pulling process.

The aluminum alloy has high strength and light material. The whole weight of the implementation device made of the materials is less than 3.5kg, and the load capacity is in the range of 5kg-25 kg. In order to improve the comfort of the backpack, a pad for supporting the back is also laid on one side of the back plate 1.
Principle of operation
As shown in fig. 6, when x is the net extension length of the spring in the drawing, there are:
Mga=Kab
Wherein a is the distance from the pulley of the first pulley block 5 to the axle center of the swinging rod 8, b is the length of the swinging rod 8, g is the gravitational acceleration, K is the spring rate coefficient, and M is the load mass.
After the initial balance state is adjusted, namely when x is the net extension length of the spring, under the same mass state, the load combined external force is constantly equal to 0 in the process of moving around the axis of the swinging rod 8, and the gravity balance requirement is met. The lower end of the spring is connected with the third guide wheel group 14 through the second flexible rope 13, a closed loop is formed integrally, the stretching amount of the spring can be changed at the position of the first pulley block 5, the net stretching amount of the spring is ensured, and loads with different qualities can be balanced. On the other hand, since the load is hung on the backpack connection plate 2, the movement form will rotate along the swing axis due to the swing of the swing lever 8, but since the load is moved substantially only in the vertical direction during the up-and-down movement of the human body, the movement of the load needs to be decomposed into the X-direction and Y-direction movements.
The present invention has been described in terms of preferred embodiments, but is not limited to the invention, and any equivalent embodiments can be made by those skilled in the art without departing from the scope of the invention, as long as the equivalent embodiments are possible using the above-described structures and technical matters.
