[0027] 1 to 11 , the present disclosure discloses a quick connection device 1000 for an electronic locking rope. The electronic locking rope 100 includes a rope core 101 and a rope sleeve 102 that covers the rope core 101. The quick connection device 1000 includes a rope connector 200 and a hollow fixing sleeve 300. The rope connector 200 is connected to the tail end of the rope sleeve 102 of the electronic locking rope 100. One end of the rope connector 200 remote from the tail end of the rope sleeve 102 includes spring leaf portions 201 that are uniformly arranged along the circumference of the rope connector 200. Each of the spring leaf portions 201 is configured to extend from the rope connector 200 in a direction that forms an acute angle with respect to the central axis of the rope connector 200. The fixing sleeve 300 is provided with an inlet 301 and an outlet 302 spaced apart from the inlet 301 along the central axis of the fixing sleeve 300. Flat portions 303 extending between the inlet 301 and the outlet 302 and corresponding one-to-one to the spring leaf portions are provided on the inner wall of the fixing sleeve 300. Protrusions 304 are provided on the inner wall between adjacent flat portions 303 at the inlet 301. The protrusions 304 protrude radially inward from the inner wall and, together with the flat portions 303, surround the inlet 301. The fixing sleeve 300 is capable of receiving the rope connector 200 through the inlet 301, so that each of the spring leaf portions 201 of the rope connector 200 expands and abuts against the axial inner wall of a corresponding one of the protrusions 304 with its axial end after the spring leaf portion 201 has completely passed through the inlet 301 along the central axis of the fixing sleeve 300. The rope connector 200 is rotatable within the fixed sleeve 300, and therefore, during the rotation process, when the rope connector 200 is rotated by a certain angle, the spring plate portions 201 are compressed towards the central axis of the fixed sleeve 300 by the corresponding flat portions 303 until the respective outer surfaces of the spring plate portions 201 match with the corresponding flat portions, and thus the rope connector 200 can be pulled out from the fixed sleeve 300.

[0028] In the embodiments shown in FIGS. 2, 4, 10, and 11, the number of spring leaf portions 201 and flat portions 303 is two, the two spring leaf portions 201 are arranged symmetrically with respect to the central axis of the rope connector 200, and the two flat portions 303 are respectively arranged on opposing inner walls of the fixing sleeve 300. Specifically, the two spring leaf portions 201 are arranged in an "eight" shape with respect to the central axis of the rope connector 200. In one embodiment according to the present disclosure, the certain angle is 90 degrees. Of course, the number of spring leaf portions 201 in the rope connector of the quick connection device for electronic ropes according to the present disclosure is not limited to two and may be three, four, or other numbers. The number of flat portions 303 is also not limited to two and may be three, four, or other numbers. Furthermore, the certain angle is not limited to 90 degrees and may be set to other values, such as 60 degrees, 30 degrees, etc., depending on the number of spring leaf portions 201 and flat portions 303.

[0029] 2 and 3 , each of the inlet 301 and the outlet 302 is disposed at a certain distance from the axial end face of the fixing sleeve 300, and thus can cover a part of the rope connector 200 after the rope connector 200 is attached to or assembled into the fixing sleeve 300, thereby protecting the rope connector 200. Furthermore, a connecting part is disposed on the outer wall of the fixing sleeve 300 to facilitate connection between the fixing sleeve 300 and an electric vehicle.

[0030] By providing the rope connector 200 and the fixing sleeve 300 to be detachable from each other, when the rope connector 200 needs to be assembled into the fixing sleeve 300, the spring plate portion 201 of the rope connector 200 is inserted into the interior of the fixing sleeve 300 through the inlet 301. After being attached or assembled into the interior of the fixing sleeve 300, each of the spring plate portions 201 expands so that the axial end of each of the spring plate portions 201 abuts against the axial inner wall of a corresponding one of the protrusions 304, preventing the rope connector 200 from coming out of the fixing sleeve 300. However, when the rope connector 200 needs to be removed from the fixing sleeve 300, the rope connector 200 is rotated within the fixing sleeve. During the rotation process, when the rope connector 200 is rotated by a certain angle, the flat portion 303 compresses the spring plate portion 201 toward the central axis of the fixed sleeve 300 until the expanded spring plate portion 201 of the rope connector 200 is compressed to an extent that it matches the flat portion 303 in the fixed sleeve 300, allowing the rope connector 200 to be pulled out of the fixed sleeve 300 through the inlet 301. Therefore, it can be seen that with the quick connection device 1000 for electronic lock ropes provided by the present disclosure, the rope connector 200 only needs to be inserted into the fixed sleeve 300 to complete the assembly of the electronic lock rope, and the rope connector 200 only needs to be rotated by a certain angle and pulled to complete the disassembly of the electronic lock rope. This not only makes the assembly and disassembly of the electronic lock rope more convenient, but also greatly improves the assembly efficiency. Furthermore, the quick connection device for electronic lock rope 1000 has a simple structure, low cost, and high reliability.

[0031] 5, 8, and 9, each of the protrusions 304 includes a guide surface 3041 located on the axial outer wall of the protrusion 304, and the shape of the guide surface 3041 is set to match the shape of the outer surface of the corresponding spring plate portion 201 so as to guide the spring plate portion 201 when the rope connector 200 is attached. Setting the guide surface 3041 not only serves to guide the rope connector 200, but also reduces resistance when the rope connector 200 is attached, making it easier to attach the rope connector 200.

[0032] 10 and 11, the outer surface of the spring plate portion 201 is an arcuate surface that protrudes outward, while the guide surface 3041 is an arcuate surface that is recessed toward the inside of the fixing sleeve 300 along the axial direction of the fixing sleeve 300, as shown in Figures 5, 8, and 9. By setting the guide surface 3041 to an arcuate surface that matches the outer surface of the spring plate portion 201, the process of attaching the rope connector 200 to the fixing sleeve 300 can be made smoother.

[0033] 5, 8, and 9, each of the protrusions 304 further includes a limiting surface 3042, which is located radially outward of the guide surface 3041 so as to axially restrict the rope connector 200 when the rope connector 200 is attached to the fixing sleeve 300. Specifically, the limiting surface 3042 is an annular surface centered on the central axis of the fixing sleeve 300.

[0034] To further enhance the guiding effect on the spring plate portion 201, notches 3043 are drilled in the protrusions 304, and the notches 3043 are configured to extend radially from the radial end faces of the protrusions 304 to the limiting surfaces 3042 so as to make the protrusions 304 discontinuous around their circumference. In the embodiment shown in FIGS. 5 and 9, one notch 3043 is provided in each of the protrusions 304, and therefore the two protrusions 304 actually include a total of four guide surfaces 3041, which can serve to center the rope connector 200 when the rope connector 200 is first installed and prevent the rope connector 200 from shifting. Furthermore, as shown in FIG. 7, the radial end faces of each of the protrusions 304 are arcuate surfaces. On the one hand, the arcuate surfaces can prevent the outer surfaces of the spring plate portions 201 of the rope connector 200 from being scratched during installation of the rope connector 200. On the other hand, the arcuate surfaces can also guide the rope connector 200 in the circumferential direction when rotating the rope connector 200, thereby avoiding jamming of the rope connector 200 during rotation.

[0035] In one embodiment, in order to increase the structural strength and rigidity of the fixing sleeve 300 and the flat portion 303, a plurality of parallel reinforcing ribs 3031 are provided on each of the flat portions 303, the reinforcing ribs 3031 being configured to extend in a direction parallel to the central axis of the fixing sleeve 300 and being spaced apart from one another. As shown in FIGS. 7 to 9, three reinforcing ribs 3031 are provided on each of the flat portions 303, and the length of each of the reinforcing ribs 3031 is shorter than the length of the flat portion 303. Naturally, the number of reinforcing ribs 3031 is not limited to three, and may be more or less than three.

[0036] Referring to FIG. 2 , a rope connector 200 according to an embodiment of the present disclosure will be described. The rope connector 200 is configured to have a threaded hole 202 penetrating the rope connector 200 along the central axis of the rope connector 200. The threaded hole 202 includes a first hole 2021 and a second hole 2022 that communicate with each other. The inner diameter of the second hole 2022 is larger than the inner diameter of the first hole 2021. The second hole 2022 is configured to accommodate the tail end of the rope sleeve 102 of the electronic lock rope 100. The first hole 2021 is configured to allow the rope core 101 of the electronic lock rope 100, extending from the tail end of the rope sleeve 102, to pass through and extend outside the rope connector 200.

[0037] In the embodiment shown in Figures 4, 10, and 11, the rope connector 200 includes a rope sleeve accommodating portion 203, a limiting flange 204, an engaging portion 205, and a main body portion 206, which are connected in series. The rope sleeve accommodating portion 203, the limiting flange 204, and the engaging portion 205 are all cylindrical, and the main body portion 206 is prismatic. The two spring plate portions 201 are respectively disposed on opposite surfaces of the main body portion 206, and the second hole portion 2022 is disposed in the rope sleeve accommodating portion 203 to accommodate the tail end of the rope sleeve 102. The outer diameter of the engaging portion 205 corresponds to the spacing between the opposing protrusions 304, so that when the rope connector 200 is attached to the fixing sleeve 300, the engaging portion 205 engages between the opposing protrusions 304. The outer diameter of the limiting flange 204 is larger than the outer diameter of the engaging portion 205 , so that when the engaging portion 205 engages between the opposing protrusions 304 , the limiting flange 204 abuts against the limiting surface 3042 of the protrusion 304 . Furthermore, as shown in FIG. 11, in order to avoid stress concentration at the connection between the main body portion 206 and the spring plate portion 201 and to increase fatigue strength at the connection, the main body portion 206 has a transition portion that is recessed inward at the connection between the main body portion 206 and the spring plate portion 201.

[0038] In the embodiment shown in FIGS. 4, 6, 8, and 9, an exit plate 305 is provided at the end of the flat portion 303 away from the entrance 301. The exit plate 305 is perpendicular to the flat portion 303, and an exit 302 is formed in the exit plate 305. Thus, the rope core 101 of the electronic lock rope 100 passes through the exit 302 and extends outside the fixed sleeve 300. In one embodiment, the exit plate 305 is a rectangular plate. Furthermore, to increase the structural strength and rigidity of the exit plate 305, two reinforcing plates are also provided on the side of the exit plate 305 away from the rope connector 200. These two reinforcing plates are configured to extend along the axial direction of the fixed sleeve 300 from two opposing surfaces of the exit plate 305 to adjacent axial end surfaces of the fixed sleeve 300 and along the height direction of the exit plate 305 to opposing inner walls of the fixed sleeve 300.

[0039] To further position the rope connector 200 axially after it is attached to the fixing sleeve 300 and to prevent the rope core 101 of the electronic lock rope 100 from damaging the fixing sleeve 300, a hollow rubber sleeve 306 having two open ends is provided on the side of the outlet plate 305 facing the entrance 301, as shown in FIGS. 1 and 2 . The end of the main body 206 remote from the rope sleeve receiving section 203 also includes a boss-shaped positioning section 207, which is connected to the end of the main body 206 by a neck 208 having an outer diameter smaller than that of the positioning section 207. During the process of gradually attaching the rope connector 200 into the fixing sleeve 300 through the entrance 301, the positioning section 207 is gradually attached to the rubber sleeve 306. Therefore, the rope core 101 of the electronic lock rope 100 extending from the positioning section 207 is always covered by the rubber sleeve 306 until it passes through the exit 302.
