[0058] In this embodiment, the elbow movable connection assembly 2 includes a connecting arm 21, an inner elbow fixing seat 23, an outer elbow fixing seat 25, an elbow servo motor 26, and an elbow rotating connector 28. The left side of the elbow rotating connector 28 is engaged and rotatably connected to the outer elbow fixing seat 25, and the right side of the elbow rotating connector 28 is engaged and rotatably connected to the inner elbow fixing seat 23.

[0063] A cover 34 is installed on the outside of the mounting slot 314, and a heat dissipation mesh is provided on the cover 34.

[0064] In this embodiment, a shoulder servo motor 310 is installed inside the shoulder hinge 35. A shoulder drive gear 311 is mounted on the output shaft of the shoulder servo motor 310. A shoulder transmission gear 313 is meshed with the left side of the shoulder drive gear 311. A shoulder driven gear 312 is installed inside the upper arm support 33, and the shoulder driven gear 312 is meshed with the shoulder transmission gear 313. Through the meshing of the shoulder drive gear 311, the transmission gear, and the driven gear, power is transmitted to the upper arm to assist in the shoulder lifting action. At the same time, the shoulder hinge 35 is hinged to the shoulder connector 41 of the back assembly 4, allowing the upper arm to move naturally in three-dimensional space, solving the problem of limited shoulder joint movement in rigid exoskeletons.

[0065] In this embodiment, the bottom of the back plate 43 is provided with a plug groove 45 for connecting to the spinal assembly 5, and two sets of plug blocks 51 adapted to the plug groove 45 are fixed on the upper side of the spinal connector 52. The plug blocks 51 are inserted into the plug groove 45 and fixedly connected to it by a pin.

[0066] In this embodiment, multiple sets of spinal modules A53 and B54 are hinged together to form a biomimetic spinal structure, which allows for natural bending when bending over. There is a gap between spinal modules A53 and B54 that can move left and right, enabling bending in the left and right directions. The left and right ends of the uppermost spinal module A53 are hinged to the spinal connector 52, and the lowermost spinal module A53 is hinged to the spinal module C55.

[0067] In this embodiment, two sets of support springs 531 are symmetrically fixed on the left and right sides of the bottom of the spinal module A53. The spinal module B54 has a spring groove 541 that matches the support springs 531. The lower end of the support spring 531 is inserted into the spring groove 541. The support spring 531 can provide elastic support when bending over and disperse the pressure on the lumbar spine.

[0068] It should be noted that the robot's main structural components are made using additive manufacturing, resulting in a lighter overall weight and improved comfort when worn.

[0069] The working principle of this logistics handling exoskeleton-assisted robot:

[0070] In actual use, the user stands up, places the lumbar support plate 61 of the lumbar support component 6 against the waist, adjusts the angle of the lumbar support modules A / B / C by rotating them through the pins to make them fit the waist curve; fastens the buckle waist belt between the two lumbar support modules C and adjusts the tightness.

[0071] Fit the backplate 43 against your back, ensuring that the bending movement part 58 of the spinal component 5 and the lumbar support plate 61 are rotatably connected in place. Adjust the length of the upper arm extension by using the adjustment groove 38 and through hole of the upper arm support 33 according to your arm length and fixing it with bolts. Fit the upper arm hand guard 32 against the inside of the upper arm and fix it with Velcro, ensuring that the electromyography sensor 39 is in close contact with the skin. Adjust the length of the forearm component 1 by using the positioning holes A / B of the forearm connector 12 and connecting support 21 according to the forearm length and fix it with bolts. Fit the two sets of curved forearm hand guards 11 against the forearm and fix them with Velcro to complete the wearing process.

[0072] When a user lifts their arm to carry heavy objects, the upper arm muscles contract, generating electromyographic (EMG) signals. The EMG sensor 39 captures these signals, which are then analyzed by the sensor processor 315. The main controller 46 then drives the shoulder servo motor 310 to rotate, providing upward auxiliary force through the upper arm support 33 and reducing the strain on the shoulder muscles. When bending or extending the forearm, changes in the EMG signals at the elbow trigger the elbow servo motor 26 to rotate, assisting the forearm movement and reducing the load on the arm muscles. When bending over to carry heavy objects, the bending motion component 58 allows the waist to bend naturally, and the spine modules A / B distribute the lumbar stress through hinges and support springs 531. When standing upright, the spinal extension axis 56 actively extends and retracts, providing upward support and assisting in straightening the waist, reducing the load on the erector spinae muscles.

[0073] Based on the above principles and processes, this exoskeleton robot can accurately respond to human movement intentions and provide targeted assistance. It can also distribute the load through a biomimetic structure, effectively reducing the risk of muscle strain during logistics and handling, while taking into account the body shape adaptability and ease of operation for different users.

[0074] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
