[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1, reference Figure 1 - Figure 2 , which is the first embodiment of the present invention, provides an upper limb back protection device of a live working support exoskeleton, including a connecting seat 101 and a safety belt 102, a connecting component 103 arranged at the lower end of the connecting seat 101, and the connecting component 103 and the safety belt 102 are fixedly connected by Velcro 104; an adjustment unit 200, including a support plate 201 and an adjustment seat 202, a shoulder pad 203 arranged on the inner side of the support plate 201, the adjustment seat 202 is fixedly connected to the upper part of the connecting seat 101, an adjustment component 204 arranged in the adjustment seat 202, and a limit component 205 arranged on the support plate 201 and matched with the adjustment component 204. The connection assembly 103 includes support rods 103a disposed on both sides of the lower end of the connection seat 101, adapter seats 103b disposed at the lower ends of the two groups of support rods 103a, an inner back tube 103c disposed at the lower end of the adapter seat 103b, and an outer back tube 103d sleeved on the inner back tube 103c. The outer walls of the inner back tube 103c and the outer back tube 103d are both provided with connection holes 103e, and the inner back tube 103c is fixedly connected by bolts that penetrate the connection holes 103e on the outer walls of the outer back tube 103d and the inner back tube 103c in sequence. It also includes a fixing component 105, which includes a fixing plate 105a, a ring clamp 105b sleeved on the outside of the outer back tube 103d, and the ring clamp 105b and the fixing plate 105a are fixedly connected; the ring clamp 105b is fixedly connected to the circular hole on the outside of the outer back tube 103d by bolts that penetrate the ring clamp 105b and the outside of the outer back tube 103d in sequence.

[0029] Furthermore, the support rod 103a is located on both sides of the lower end of the connecting seat 101, providing vertical support force, connecting the connecting seat 101 with the adapter seat 103b, and can withstand more gravity and pressure, reducing the structural deformation caused by gravity. The inner back tube 103c is located at the lower end of the adapter seat 103b, and the outer back tube 103d is sleeved on the outside of the inner back tube 103c, and together with the inner back tube 103c constitute a back tube system.

[0030] The inner back tube 103c is provided with five groups of connection holes 103e, and the outer back tube 103d is provided with one group of connection holes 103e. The five groups of connection holes 103e of the inner back tube 103c provide multiple fixing points, so that the outer back tube 103d can be fixedly connected with the inner back tube 103c at different heights. The height of the back tube system can be precisely adjusted according to the height and body shape of the wearer to ensure the best fit and comfort. Through the bolt connection, the operator can quickly adjust the height of the back tube system without complicated adjustment process. This design simplifies the steps of wearing and adjustment and improves the working efficiency.

[0031] During use, the hollow rectangle formed by the support rods 103a on both sides can accommodate the back buckle of the safety belt 102 after the device is adjusted to the appropriate specifications. Velcro 104 can be installed on the inner side of the hollow rectangle (the upper side of the adapter seat 103b and the lower side of the connecting seat 101) to form a quick-sticking structure between the buckle and the device. The design of the hollow rectangle enables the back structure of the device to accommodate the back buckle of the safety belt 102, avoiding physical conflict between the external device and the safety belt 102, ensuring that the two can be used at the same time without affecting their respective functions. The quick-sticking structure provided by Velcro 104 allows the safety belt 102 buckle to be quickly fixed to the exoskeleton, and is also convenient for quick removal. This design improves the efficiency of donning and doffing, especially in emergency situations where quick response is crucial.

[0032] Example 2, reference Figure 2 - Figure 7, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the adjustment unit 200 includes a support plate 201 and an adjustment seat 202, a shoulder pad 203 arranged on the inner side of the support plate 201, the adjustment seat 202 is fixedly connected to the upper part of the connection seat 101, an adjustment component 204 arranged in the adjustment seat 202, and a limit component 205 arranged on the support plate 201 and matched with the adjustment component 204, and the adjustment component 204 includes a displacement groove 204a arranged in the adjustment seat 202, a reset groove 204b arranged near both sides of the displacement groove 204a, and a button 204c arranged in the reset groove 204b. The upper end of the button 204c is elastically connected to the reset groove 204b by a spring 204d, and the lower end of the button 204c protrudes a part of the lower end of the adjustment seat 202. The position limiting assembly 205 includes two groups of position limiting plates 205a disposed at the rear of the two groups of support plates 201, a slide groove 205b disposed on the rear surface of the position limiting plates 205a, and a position limiting groove 205c disposed in the slide groove 205b. A fixing pin 205d disposed on the inner side of the button 204c is cylindrical and is adapted to the position limiting. The two groups of support plates 201 and the position limiting plates 205a are mirror-imaged, and the two groups of position limiting plates 205a are staggered in the displacement groove 204a.

[0033] Furthermore, the adjustment seat 202 is fixedly connected to the upper part of the connecting seat 101, and the shoulder pad 203 is arranged on the inner side of the support plate 201 to protect the user's shoulders. The shoulder pad 203 can reduce the pressure of the exoskeleton on the user's shoulders and improve the wearing comfort. The displacement groove 204a is arranged in the adjustment seat 202 to guide the horizontal movement of the limit plate 205a. The reset groove 204b is arranged on the inner wall of the displacement groove 204a near both sides to fix the position of the button 204c and also to guide the vertical movement of the button 204c. The spring 204d enables the button 204c to automatically reset after being released.

[0034] Furthermore, the limiting plates 205a are arranged at the rear of the two groups of support plates 201 and are slidably connected in the limiting grooves 205c. The staggered limiting plates 205a can make more effective use of space, and can expand the movable range of the limiting plates 205a in the displacement grooves 204a, which means that the adjustment range of the support plates 201 is also expanded. The staggered limiting plates 205a allow the limiting plates 205a to make more effective use of space. This layout reduces the volume of the device, while maintaining the adjustment function and reducing the burden of the device equipment on the staff. At the same time, the movable range of the limiting plates 205a in the displacement grooves 204a is expanded, which means that the adjustment range of the support plates 201 is also expanded. This provides more adjustment options for the staff to adapt to different body sizes and wearing requirements.

[0035] The slide groove 205b is arranged on the rear surface of the limit plate 205a, providing a guide path for the fixed pin 205d. The slide groove 205b allows the limit plate 205a to move freely in the displacement groove 204a, which is the key to achieve the adjustment of the support plate 201. The limit plate 205a can slide along a predetermined path in the slide groove 205b to adjust the position of the support plate 201. There are a number of limit grooves 205c, which are evenly distributed on the inner wall of the lower side of the slide groove 205b, and are used to cooperate with the fixed pin 205d. When the fixed pin 205d is located in the limit groove 205c, it locks the limit plate 205a to prevent it from accidentally moving horizontally in the displacement groove 204a. The existence of the limit groove 205c ensures that the limit plate 205a can accurately stay in the predetermined position during the adjustment process, thereby achieving the adjustment of the positions of the two groups of support plates 201, so as to adapt to the shoulder width of various different people;

[0036] The staff applies upward pressure to the button 204c to make the fixing pin 205d disengage from the limiting groove 205c, thereby releasing the lock of the limiting plate 205a. At this time, the limiting plate 205a can move freely in the slide groove 205b to adjust the support plate 201. After the adjustment is completed, the staff releases the button 204c, and the fixing pin 205d resets under the action of the spring 204d, re-enters the limiting groove 205c, locks the limiting plate 205a, and fixes the position of the support plate 201.

[0037] The fixing pin 205d is arranged on the inner side of the button 204c, and is cylindrical and matched with the limiting groove 205c. When pressure is applied upward to the button 204c, the fixing pin 205d will disengage from the limiting groove 205c, and the fixing pin 205d will enter the range of the sliding groove 205b. The limiting plate 205a is not constrained by the fixing pin 205d, and can slide in the horizontal direction, thereby realizing the sliding of the support plate 201 to the left or right direction to achieve shoulder adjustment. After the adjustment is completed, the button 204c is released, and the elastic potential energy of the spring 204d is used to push the button 204c to reset, thereby driving the fixing pin 205d to slide back into the limiting groove 205c. Since the fixing pin 205d and the limiting groove 205c are matched, the fixing pin 205d is clamped in the limiting plate 205a. At this time, the limiting plate 205a cannot continue to move horizontally, thereby achieving the effect of fixed shoulder adjustment.

[0038] The remaining structures are the same as those of Example 1.

[0039] Example 3, reference Figure 6, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the disassembly component 206 includes a block 1 206a arranged on the upper inner wall of the slide groove 205b, and a block 206b arranged on the lower inner wall of the slide groove 205b; the block 1 206a and the block 2 206b are cross-arranged.

[0040] Furthermore, the upper and lower inner walls of the two groups of slide grooves 205b are both provided with a stop block 1 206a and a stop block 206b, which are cross-arranged. The setting of the stop block 1 206a and the stop block 206b makes the original path of the slide groove 205b narrower and curved, and the limit plate 205a cannot be moved out of the displacement groove 204a by simple horizontal sliding, thereby overcoming the contact resistance between the stop block 1 206a and the stop block 206b and the fixing pin 205d.

[0041] The other sides of the first and second blocks 206a and 206b are perpendicular to the inner wall of the slide groove 205b, so that when the limit plate 205a needs to move out of the displacement groove 204a, the position of the button 204c needs to be changed according to the position of the first and second blocks 206a and 206b, so as to achieve the contact range of the fixed pin 205d out of the first and second blocks 206a and 206b. One side of the first and second blocks 206a and 206b is inclined, which makes it very convenient to install the limit plate 205a in the displacement groove 204a. It is necessary to first set the fixed pin 205d on the path between the slide grooves 205b, and use the inclined surface to guide the movement of the fixed pin 205d. The inclined surface can guide the fixed pin 205d to move along a specific path to reduce the contact resistance, that is, the fixed pin 205d drives the button 204c to increase or decrease the pressure applied to the spring 204d, so as to change the height of the fixed pin 205d in the reset groove 204b.

[0042] The remaining structure is the same as that of Example 2.
