[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] To provide a more complete and detailed description of this disclosure, the following illustrative descriptions of embodiments and examples of the present invention are provided; however, these descriptions are not intended to be the only ways to implement or use the embodiments of the present invention. The embodiments cover features of various embodiments, as well as the method steps and sequences for constructing and operating these embodiments. However, other embodiments may be used to achieve the same or equivalent functionality and sequence of steps.

[0041] Figure 1 schematically shows the application principle of the energy chain. The protective sleeve in the energy chain seals and wraps the pipeline. One or both ends of the energy chain along the longitudinal direction are fixed to the equipment. Both ends can be stationary, or one end can be stationary and the other end can move, or both ends can move. When in motion, the energy chain bends in one direction with a curvature not less than a specified value, and cannot bend in other directions. As shown in the schematic diagram, one end of the energy chain is fixed at point O, and the other end is fixed at point A. Point O is fixed and stationary, and point A moves with the equipment. As indicated by the dotted line, the energy chain is located at one end of point A and bends to point B within the specified curvature range.

[0042] Referring to Figures 2 and 3 , an energy chain according to an embodiment of the present invention includes a protective sleeve 10, a keel 20, an upper cover crossbar 30, and a lower cover crossbar 40. The protective sleeve 10 comprises an upper cover 101 and a lower cover 102, which dust-tightly encase the pipelines. Both the upper cover 101 and the lower cover 102 are flexible hoses, allowing the protective sleeve 10 to bend toward the upper cover 101 at a curvature not less than a predetermined value. When the pipelines are enclosed within the protective sleeve 10, the protective sleeve 10 and the keel 20 bend synchronously.

[0043] The upper cover crossbar 30 is fixed to the surface of the upper cover 101, and at least one crossbar is provided in a transverse direction perpendicular to the longitudinal direction of the upper cover 101. The lower cover crossbar 40 is fixed to the surface of the lower cover 102, and at least one crossbar is provided in a transverse direction perpendicular to the longitudinal direction of the lower cover 102. The keels 20 are symmetrically arranged on both sides of the protective sleeve 10 along the longitudinal direction thereof, and are placed between the upper cover crossbar 101 and the lower cover crossbar 102. One side of the keel 20 along the longitudinal direction is movably connected to the upper cover crossbar 30, and the other opposite side is movably connected to the lower cover crossbar 40. A gap exists between the keel 20 and the protective sleeve 10. When the keel 20 bends on the side of the protective sleeve 10 facing the upper cover 101, it limits the bending of the protective sleeve 10 to a fixed curvature radius and restricts the bending of the protective sleeve 10 facing the lower cover 102.

[0044] Referring to Figures 4 and 6 , the keel 20 comprises a flexible centerline pivot bar 201, upper stoppers 202 arranged at equal intervals along the longitudinal direction of the centerline pivot bar 201, and lower stoppers 203 arranged on the opposite side of the centerline pivot bar 201, aligned with the upper stoppers 202. Along the longitudinal direction, opposing sides of the centerline pivot bar 201 are perpendicularly connected to opposing support rods, with the upper stoppers 202 and lower stoppers 203 each perpendicularly connected to the support rod on the same side. A slot is defined on each of the upper and lower stoppers 202 and 203, the ends opposite to the support rods. The card slot on the upper stop piece 202 cooperates with the snap fastener on the upper cover cross bar 30 to realize the movable connection between the upper stop piece 202 and the upper cover cross bar 30; the card slot on the lower stop piece 203 cooperates with the snap fastener on the lower cover cross bar 40 to realize the movable connection between the lower stop piece 203 and the lower cover cross bar 40.

[0045] When the protective sleeve 10 bends, the center axis bar 201 undergoes flexible deformation, so that when the protective sleeve 10 bends toward the side of the upper cover 101, the adjacent upper stop pieces 202 gradually approach until they conflict with each other, limiting the bending of the protective sleeve 10 within a fixed curvature radius. When the protective sleeve 10 tends to bend toward the side of the lower cover 102, the adjacent lower stop pieces 203 directly or indirectly conflict with each other, thereby limiting the bending of the protective sleeve 10 toward the side of the lower cover 102.

[0046] In this embodiment of the present invention, an adjustment stop piece 204 is provided between adjacent lower stop pieces 203 on the center axis bar 201. The spacing between the lower stop piece 203 and the adjustment stop piece 204 is smaller than the spacing between adjacent upper stop pieces 201. When the protective sleeve 10 tends to bend toward the lower cover 102, the adjacent lower stop pieces 203 respectively come into contact with the adjustment stop piece 204, achieving indirect contact therebetween, thereby limiting the bending of the protective sleeve 10 toward the lower cover 102. The adjustment stopper 204 is movably buckled onto the centerline rotating shaft bar 201. In an embodiment of the present invention, the adjustment stopper 204 is buckled into a connection with a support rod vertically connected to the centerline rotating shaft bar 201. The support rod connected to the adjustment stopper 204 is in an inverted "T" shape. One end of the adjustment stopper 204 is provided with an open rectangular slot. Through the buckle of the rectangular slot and the inverted "T"-shaped support rod, the adjustment stopper 204 is movably connected to the centerline rotating shaft bar 201. Since the adjustment stopper 204 is movably connected to the centerline rotating shaft bar 201, it is convenient to replace the adjustment stopper 204. By replacing the adjustment stopper 204 of different sizes and adjusting the distance between the lower stopper 203 and the adjustment stopper 204, the keel 20 has an adjustable stop function, thereby adjusting the anti-flexural force of the energy chain and ultimately achieving the adjustment of the overhead length of the energy chain.

[0047] The centerline pivot bar 201, upper stopper 202, and lower stopper 203 of the keel 20 are integrally injection-molded. Because the centerline pivot bar 201 is infinitely extendable, it offers more stable performance than traditional spliced ​​or snap-on keels. With the exception of the centerline pivot bar 201, which is made of a flexible plastic material, all other components of the keel 20 are made of a rigid plastic material.

[0048] In other optional embodiments, there are no adjustment stop pieces 204 between adjacent lower stop pieces 203. The spacing between the lower stop pieces 203 is pre-designed based on the overhead length requirement. When the protective sleeve 10 tends to bend toward the side facing the lower cover 102, the adjacent lower stop pieces 203 directly contact each other, thereby limiting the bending of the protective sleeve 10 toward the side facing the lower cover 102.

[0049] The keels 20, symmetrically arranged on either side of the longitudinal direction of the protective sleeve 10, are movably connected to the upper cover crossbar 30 and the lower cover crossbar 40, respectively, which are fixed to the contour surface of the protective sleeve 10. Referring to Figures 5 to 11, in this embodiment of the present invention, the upper cover 101 and the lower cover 102 of the protective sleeve 10 are corrugated hoses with alternating peaks and troughs forming a corrugated profile. The upper cover crossbar 30 is fixed to the peak surface of the corrugated profile of the upper cover 101, and the lower cover crossbar 40 is fixed to the peak surface of the corrugated profile of the lower cover 102.

[0050] The surface of the wave crest of the upper cover 101 corrugated profile where the upper cover cross bar 30 is not fixed is higher than the surface of the upper cover cross bar 30, and the surface of the wave crest of the lower cover 102 corrugated profile where the lower cover cross bar 40 is not fixed is higher than the surface of the lower cover cross bar 40, so that when the energy chain is running on the ground, the upper cover cross bar 30 and the lower cover cross bar 40 can be prevented from rubbing against the ground, thereby affecting the stability of the energy chain and avoiding the generation of noise. The width of the wave crest surface of the corrugated profile of the upper cover cross bar 30 on the upper cover 101 is smaller than the width of the wave crest surface of the corrugated profile of the lower cover cross bar 40 on the lower cover 102, so that when the protective sleeve 10 is bent toward the side of the upper cover 101, more corrugation folding space can be reserved when the corrugations of the upper cover 101 are folded together, thereby extending the service life of the corrugations and making them less likely to break.

[0051] The upper cover crossbar 30 includes an upper cover long plate 301 and an upper cover fastening section 302 extending symmetrically outward from the surface of the upper cover long plate 301. The lower cover crossbar 40 includes a lower cover long plate 401 and a lower cover fastening section 402 extending symmetrically outward from the surface of the lower cover long plate 401. The width of the upper cover long plate 301 is smaller than that of the lower cover long plate 402. The upper cover long plate 301 is fixed to the peak surface of the corrugated profile of the upper cover 101, and the lower cover long plate 401 is fixed to the peak surface of the corrugated profile of the lower cover 102. The fixing method can be rubber encapsulation, glue potting, adhesive bonding, anchor nails, external fasteners, etc., which are not limited by the present invention.

[0052] In the embodiment of the present invention, the cross-sectional shapes of the upper cover 101 and the lower cover 102 are both approximately semi-elliptical, and the crests in the corrugated profile have a horizontal section parallel to the longitudinal section of the protective sleeve 10, and arc sections that bend inward at both ends of the horizontal section. The upper cover long plate 301 of the upper cover cross bar 30 is fixed to the horizontal section of the wave peak in the corrugated profile of the upper cover 101, and the upper cover fastening section 302 is fitted and fixed to the arc section of the wave peak in the corrugated profile of the upper cover 101; the lower cover long plate 401 of the lower cover cross bar 40 is fixed to the horizontal section of the wave peak in the corrugated profile of the lower cover 102, and the lower cover fastening section 402 is fitted and fixed to the arc section of the wave peak in the corrugated profile of the lower cover 102; the surface of the horizontal section of the wave peak in the corrugated profile of the upper cover 101 where the upper cover cross bar 30 is not fixed is higher than the surface of the upper cover long plate 301, and the surface of the horizontal section of the wave peak in the corrugated profile of the lower cover 102 where the lower cover cross bar 40 is not fixed is higher than the surface of the lower cover long plate 401.

[0053] The upper cover crossbars 30 are arranged at equal intervals on the contour surface of the upper cover 101; and the lower cover crossbars 40 are arranged at equal intervals on the contour surface of the lower cover 102 in alignment with the upper cover crossbars 30. In this embodiment of the present invention, the upper cover crossbars 30 are arranged at equal intervals on the peak surface of the contour of the upper cover 101, and the lower cover crossbars 40 are arranged at equal intervals on the peak surface of the contour of the lower cover 102 in alignment with the upper cover crossbars 30. The aligned upper cover crossbars 30 and lower cover crossbars 40 constitute a set of crossbars. In other optional embodiments, the crossbars of each set may not be arranged at equal intervals, but may be arranged at unequal intervals.

[0054] At least one of the multiple groups of crossbars includes a lower cover crossbar 40 with at least one fastening post 403 perpendicularly disposed on the surface fixed to the contour surface of the lower cover 102. The fastening post 403 can be integrally formed with the lower cover crossbar 40. Correspondingly, the upper cover crossbar 30 aligned with the lower cover crossbar 40 with the fastening post 403 is provided with a receiving hole. The fastening post 403 passes through the surface of the lower cover 102 and the surface of the upper cover 101 in sequence and is fixed in place with the receiving hole on the upper cover crossbar 30. The fastening post 403 between the upper cover crossbar 30 and the lower cover crossbar 40 can facilitate the separation of the pipelines inside the protective sleeve 10 to prevent the pipelines from being entangled and rubbed, and can also enhance the snap-fitting force between the upper cover 101 and the lower cover 102 to prevent them from bursting outward. In this embodiment of the present invention, the lower cover crossbar 40 included in each group of crossbars is provided with a fastening post 403 that is fixed in place with the upper cover crossbar 30.

[0055] The upper cover 101 and the lower cover 102 of the protective sleeve 10 have similar profiles. Please refer to Figures 12 and 13. In the embodiment of the present invention, the upper cover 101 and the lower cover 102 have the same profile. Please continue to refer to Figures 7 and 9. The upper cover 101 extends outward on both sides along its longitudinal direction to form an upper cover side 1011, and the lower cover 102 extends outward on both sides along its longitudinal direction to form a lower cover side 1021. The upper cover side 1011 and the lower cover side 1021 are connected by tooth buckles. In the embodiment of the present invention, in each set of tooth buckles of the upper cover side 1011 and the lower cover side 1021, the upper cover side 1011 has two upper buckles and the lower cover side 1021 has one lower buckle. After engagement, the surfaces of the upper buckle teeth and the lower buckle teeth fit together. The tooth-button engagement connection between the upper cover side 1011 and the lower cover side 1021 may be other ways, or even other movable connection ways, and the present invention does not limit this.

[0056] The junction of the upper cover side 1011 and the lower cover side 1021 forms the central axis of the protective sleeve 101. This means that the upper and lower covers 101, 102, with identical corrugated profiles, are symmetrically arranged, resulting in smoother energy chain operation and easier manufacturing. A gap exists between the keels 20, symmetrically arranged on either side of the protective sleeve 10, and the upper and lower cover sides 1011 and 102, preventing friction during bending and preventing the generation of dust.

[0057] The upper cover crossbar 30, fixed to the peak surface of the corrugated profile of the upper cover 101, extends toward the central axis and is fastened to the surface of the upper cover side 1021. The lower cover crossbar 40, fixed to the peak surface of the corrugated profile of the lower cover 102, extends toward the central axis of the protective sleeve and is fastened to the surface of the lower cover side 1021. In this embodiment of the present invention, the upper cover fastening section 302 of the upper cover crossbar 30 is fixed to the upper cover side 1011, and the lower cover fastening section 402 of the lower cover crossbar 40 is fixed to the lower cover side 1021. The upper cover fastening section 302 and the lower cover fastening section 402 are pressed together, making the protective sleeve 10 more secure and less prone to cracking.

[0058] Continuing with Figures 2 and 3 , the energy chain provided by the present invention also includes a fixing joint 50 disposed on at least one end of the protective sleeve 10. The fixing joint 50 is disposed on the outside of the keel 20 and is locked and fastened to the keel 20 located on its inside. In this embodiment of the present invention, two parallel rows of screw holes are defined on the side of the fixing joint 50. Corresponding screw holes are also defined on the upper and lower stoppers 202 of the keel 20. Once the screw holes are aligned, the fixing joint 50 and the keel 20 are secured using screws.

[0059] Please refer to Figures 15 and 16. Another embodiment of the energy chain provided by the present invention is different from the embodiment shown in Figures 1 to 14 in that the upper cover 101a and the upper cover 102a of the protective sleeve 10a are hoses without a corrugated profile, the cross-sectional shape of the protective sleeve 10a is rectangular, the upper cover 101a has no upper cover side, and the lower cover 102a has no lower cover side. Correspondingly, a rectangular accommodating space is formed between the upper cover fastening sections of the upper cover cross bar 30a, and a rectangular accommodating space is formed between the lower cover fastening sections of the lower cover cross bar 40a; the surface of the upper cover long plate of the upper cover cross bar 30a is higher than the contour surface of the upper cover 101a contour where the upper cover cross bar 30 is not fixed, and the surface of the lower cover long plate of the lower cover cross bar 40a is higher than the contour surface of the lower cover 102a contour where the lower cover cross bar 40 is not fixed; the upper cover 101a and the lower cover 102a can be fastened together by buckling them up and down, and fastened by means of tooth buckles, screws, etc. on the sides of the two, or other movable connection methods can be used. Apart from these structural features, the energy chain provided in this embodiment is the same as that in the embodiments shown in Figures 1 to 14. Please refer to the above for details and will not be repeated here.

[0060] In an optional embodiment, based on the energy chain provided by the embodiments shown in Figures 15 and 16 of the present invention, since the upper cover 101a and the upper cover 102a of the protective sleeve 10a are hoses without a corrugated profile, when the energy chain moves to the ground, the upper cover cross bar 30a and the lower cover cross bar 40a respectively fixed on the contour surface of the upper cover 101a and the contour surface of the lower cover 102a are in contact with the ground, and the width of the upper cover cross bar 30a on the contour surface of the upper cover 101a can be widened and set to an arc-shaped top surface, and the width of the lower cover cross bar 40a on the contour surface of the lower cover 102a can be widened and set to an arc-shaped top surface.

[0061] The energy chain provided by the present invention comprises a flexible centerline rotating axis bar, an upper stop plate and a lower stop plate keel, which cooperate with an upper cover cross bar and a lower cover cross bar fixed on the surface of the protective sleeve, thereby increasing the overhead length. At the same time, the pipeline is wrapped in the protective sleeve, limiting the bending radius, improving the sealing performance, and being convenient.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
