[0046] This disclosure provides a fast battery swapping lock body for new energy vehicles, such as... Figures 1-17 As shown, the fast battery swapping lock body for new energy vehicles includes a bracket part 1, a main connecting part 2, and a battery swapping connecting part 3 connected in sequence. The bracket part 1 can be installed on the vehicle structure, and the battery swapping connecting part 3 is connected to the battery swapping device for the vehicle. The main connecting part 2 realizes the connection and locking between the bracket part 1 and the battery swapping connecting part 3. In this embodiment, the fast battery swapping lock body for new energy vehicles can connect the battery swapping device to the vehicle structure and facilitate loading and unloading operations.

[0047] Specifically, the bracket part 1 is used to connect with the vehicle structure, and includes a bracket plate 11. A mounting seat 12 is provided on the bracket plate 11. The bracket plate 11 is provided with fixing holes, which are provided, for example, at the corners of the bracket plate 11. The bracket part 1 can be installed at a designated position on the vehicle structure through the cooperation of the fixing holes and fasteners.

[0048] Furthermore, the mounting base 12 includes two opposing mounting base plates 121, which are perpendicular to the support plate 11. The mounting base plates 121 can be, for example, triangular in shape. A mounting base plate 122 is disposed between the mounting base plates 121, and the mounting base plate 122 is perpendicular to the support plate 11. The mounting base plate 122 has a first mounting hole 123, which facilitates the mounting of the main connecting part 2 onto the support part 1.

[0049] Furthermore, the main connecting part 2 is connected to the bracket part 1, and particularly to the mounting base plate 122 of the mounting base 12. It includes a nut sleeve assembly 21 and a bolt assembly 22. The nut sleeve assembly 21 is disposed within the bracket part 1, particularly on one side of the mounting base plate 122, and the bolt assembly 22 is disposed outside the bracket part 1, particularly on the opposite side of the mounting base plate 122. Specifically, the nut sleeve assembly 21 is disposed within the space enclosed by the mounting base upright plate 121 and the mounting base plate 122 and surrounds the first mounting hole 123.

[0050] Further, the nut sleeve assembly 21 includes a housing 211, which covers the mounting base plate 122. A fixing seat 212 is disposed within the housing 211, and the fixing seat 212 surrounds the first mounting hole 123. Specifically, the housing 211 includes a shell 2111, which is disposed on the mounting base plate 122 and covers the first mounting hole 123. Preferably, the side of the shell 2111 is provided with a flange 2112, which allows it to be connected to the mounting base plate 122 for fixing the housing 211 on the mounting base plate 122.

[0051] Furthermore, the fixing base 212 includes a fixing plate 2121, which is attached to the mounting base base plate 122. The fixing plate 2121 is provided with a second mounting hole 2122, which is opposite to and coaxially arranged with the first mounting hole 123. A nut sleeve 2123 is provided on the fixing plate 2121 and around the second mounting hole 2122. The nut sleeve 2123 is directly opposite to the first mounting hole 123, extends toward the bracket part 1 and has a certain length, and the inner side of the nut sleeve 2123 is provided with an internal thread.

[0052] It should be noted that the thickness of the outer shell 211 can be greater than the height of the fixing base 212. Of course, the thickness of the outer shell 211 can also be greater than the thickness of the fixing plate 2121, but less than the height of the fixing base 212, so that the nut sleeve 2123 can pass through the top of the outer shell 211. No further limitation is made here.

[0053] Furthermore, the bolt assembly 22 includes a bolt sleeve 221, the upper end face of which is in contact with the bottom surface of the mounting base plate 122. A through hole is provided on the upper end face of the bolt sleeve 221, and a movable locking bolt 222 is provided inside the bolt sleeve 221. The locking bolt 222 can move up and down, thereby extending out of the through hole of the bolt sleeve 221 and extending into the nut sleeve assembly 21 through the first mounting hole 123. After entering the nut sleeve assembly 21, the locking bolt 222 is connected to the nut sleeve 222.

[0054] Furthermore, the locking bolt 222 includes a bolt body 2221, on which an anti-loosening toothed disc 2222 is provided. The anti-loosening toothed disc 2222 is, for example, sleeved in the middle position of the bolt body 2222 and extended radially. Preferably, a first tooth structure 2222a is provided on the outer edge of the anti-loosening toothed disc 2222.

[0055] Furthermore, the bolt body 2221 is divided into two segments: a first segment from the position of the anti-loosening toothed disc 2222 to the end of the bolt body 2221 facing the nut sleeve assembly 21, and a second segment from the anti-loosening toothed disc 2222 to the end of the bolt body 2221 away from the nut sleeve assembly 21. At least a portion of the first segment is a threaded segment 2223, that is, the first segment is a cylindrical structure with external threads on at least a portion of its outer surface, thereby forming the threaded segment 2223.

[0056] The threaded segment 2223 is located near the end of the bolt body 2221 facing the nut sleeve assembly 21. The threaded segment 2223 on the bolt body 2221 can extend into the nut sleeve 2123 and mesh with the internal thread of the nut sleeve 2123. The length of the threaded segment 2223 matches the length of the nut sleeve 2123 to form a stable meshing relationship.

[0057] Preferably, the end of the bolt body 2221 facing the nut sleeve assembly 21 is a frustum or a truncated cone structure, which facilitates its insertion into the nut sleeve assembly 21.

[0058] Furthermore, a bolt tightening sleeve 223 is movably fitted onto the second segment of the bolt body 2221. The cross-section of the second segment is polygonal, for example, quadrilateral, and the bolt tightening sleeve 223 can move along the second segment.

[0059] Furthermore, an anti-loosening toothed ring 224 is provided on the inner side of the bolt sleeve 221. The anti-loosening toothed ring 224 is made of an elastic material to be elastic, and the inner side of the anti-loosening toothed ring 224 cooperates with the outer side of the bolt body 2221. Specifically, the anti-loosening toothed ring 224 has an annular toothed ring base 2241, the outer diameter of which matches the inner diameter of the bolt sleeve 221. Multiple axially extending toothed ring portions 2242 are spaced along the toothed ring base 2241, and these toothed ring portions 2242 extend axially along the inner surface of the bolt sleeve 221. The multiple toothed ring portions 2242 are evenly distributed relative to the toothed ring base 2241.

[0060] Furthermore, the end of the toothed ring portion 2242 has an anti-loosening protrusion 22421, which abuts against the inner side of the upper surface of the bolt sleeve 221 and cooperates with the anti-loosening toothed disc 2222. The surface of the anti-loosening protrusion 22421, that is, the surface facing the bolt body 2221, is provided with a second tooth structure 22421a, which cooperates with the first tooth structure 2222a.

[0061] Furthermore, a limiting groove 22422 is provided on the gear ring portion 2242, and the limiting groove 22422 and the bolt tightening sleeve 223 can be engaged with each other. The space between the anti-loosening protrusion 22421 on the gear ring portion 2242 and the limiting groove 22422 is the gear disc travel section, and the anti-loosening gear disc 2222 moves within the gear disc travel section.

[0062] Furthermore, the bolt tightening sleeve 223 includes a tightening sleeve base 2231, on which a tightening sleeve 2232 is disposed. The tightening sleeve base 2231 is in contact with the anti-loosening toothed disc 2222. The inner side of the tightening sleeve 2232 is polygonal, for example, quadrilateral, to facilitate matching with the second section of the bolt body 2221, thereby facilitating the movement of the tightening sleeve 2231 along the second section. The outer surface of the tightening sleeve 2232 has a third tooth structure 2233.

[0063] To restrict the bolt tightening sleeve 223, the limiting groove 22422 has a first groove wall 22422a and a second groove wall 22422b arranged opposite to it. The first groove wall 22422a is perpendicular to the moving direction of the bolt tightening sleeve 223, and the second groove wall 22422b is inclined relative to the first groove wall 22422a. When the bolt tightening sleeve 223 is fixed through the limiting groove 22422, the tightening sleeve base 2231 is embedded in the limiting groove 22422, with its lower surface abutting against the first groove wall 22422a and its upper surface abutting against the second groove wall 22422b.

[0064] Furthermore, the bolt tightening sleeve 223 is connected to the battery swapping connection part 3, wherein the battery swapping connection part 3 includes a connection part body 31, the first end of the connection part body 31 is provided with a first receiving groove 32, and the second section of the bolt body 2221 can extend into and be received in the first receiving groove 32.

[0065] Specifically, the tightening sleeve 2232 of the bolt tightening sleeve 223 is connected to the power swapping connection part 3. A fourth tooth structure 321 is provided on the inner side of the groove of the first receiving groove 32. The fourth tooth structure 321 is engaged with the third tooth structure 2233 on the outer surface of the tightening sleeve 2232, thereby driving the power swapping connection part 3 to move when the bolt tightening sleeve 223 moves.

[0066] Furthermore, an elastic element 323 is provided at the bottom of the first receiving groove 32, and a groove 2224 is provided at the end of the second section of the bolt body 2221. When the bolt body 2221 extends into the first receiving groove 32, the elastic element 323 abuts against the bottom of the groove 2224.

[0067] Furthermore, a second receiving groove 33 is provided at the second end of the connecting part body 31. The cross-section of the second receiving groove 33 is polygonal, for example, it can be a quadrilateral. The connection with the vehicle's battery swapping device is achieved through the second receiving groove 33.

[0068] When the battery swapping connection 3 moves toward the nut sleeve assembly 21, it drives the bolt body 2221 to move toward the nut sleeve assembly 21. At the same time, under the action of the elastic element 323, the bolt tightening sleeve 223 is fixed in the limiting groove 22422. As the anti-loosening toothed disc 2222 gradually moves to the top, the tightening sleeve base 2231 presses against the second groove wall 22422b due to the axial force. Under the action of elasticity, the anti-loosening protrusion 22421 moves radially away from the bolt body 2221, so that when the upper surface of the anti-loosening toothed disc 2222 can fit against the top inner surface of the bolt sleeve 221, the bolt tightening sleeve 223 is released so that the tightening sleeve base 2231 no longer presses against the second groove wall 22422b. This allows the second tooth structure 22421a to engage with the first tooth structure 2222a on the anti-loosening toothed disc 2222, thereby locking the locking bolt 222 and the anti-loosening toothed ring 224 to prevent the bolt body 2221 from continuing to rotate.

[0069] The embodiments disclosed herein facilitate a tight connection between the battery swapping device and the vehicle, and can be locked after connection to prevent loosening, ensuring the connection stability of the battery swapping device while also providing high safety.
