[0049] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0050] It should be noted that, in order to more clearly describe the quick-change structure and quick-change system in the present invention, the term "distal end" is defined below to mean the end of the quick-change structure that is away from the operator during use, and the term "proximal end" is defined to mean the end of the quick-change structure that is close to the operator during use. Unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as those generally understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0051] Embodiment 1:

[0052] Ginseng Figures 1 to 9 The figure shows a quick-change structure in an embodiment of the utility model, which includes a sleeve 1, a sliding member 2, a driving assembly 3 and a plurality of telescopic members 4.

[0053] Specifically, the sleeve 1 is provided with a plurality of openings 11 along the circumferential direction, the sliding member 2 is installed inside the sleeve 1 along the axial direction of the sleeve 1, the driving assembly 3 abuts against the proximal end of the sliding member 2, and drives the sliding member 2 to move from the proximal end to the distal end along the axial direction of the sleeve 1, and the telescopic member 4 is distributed along the circumferential direction of the sleeve 1, and the telescopic member 4 can be a flat plate structure, and the shape of the flat plate can be arc-shaped, square-shaped, etc. The first end 41 of the telescopic member 4 abuts against the proximal end of the sliding member 2, and the second end 42 of the telescopic member 4 passes through the opening 11. Among them, a guide structure is provided on the proximal end of the sliding member 2 and / or the first end 41 of the telescopic member 4, and the guide structure is used to convert the movement of the sliding member 2 from the proximal end to the distal end along the axial direction of the sleeve 1 into the movement of the telescopic member 4 radially toward the outside of the sleeve 1.

[0054] In this embodiment, the sleeve 1 can be inserted into the hole on the external component, and after the driving component 3 pushes the sliding member 2 to move, the guide structure converts the axial motion state of the sliding member 2 into a radial motion state, and transmits the radial motion state to the telescopic member 4, so that the telescopic member 4 extends from the opening 11 of the sleeve 1 and abuts against the hole on the external component of the sleeve 1, thereby realizing the internal support fixation of the external component. Similarly, when the external component needs to be removed, it is only necessary to move the sliding member 2 in the opposite direction, so that the telescopic member 4 is no longer pushed by the sliding member 2, and the telescopic member 4 no longer generates an internal support force on the hole on the external component, and the external component can be quickly detached from the fixation.

[0055] Ginseng Figure 3 , Figure 4 As shown, the guide structure in this embodiment includes a first guide surface 21 located at the distal end of the sliding member 2 and a second guide surface 43 located at the first end 41 of the telescopic member 4, and the first guide surface 21 abuts against the second guide surface 43. The guide structure adopts a surface-to-surface contact connection method, which can avoid damage to the end surfaces of the telescopic member 4 and the sliding member 2, and improve the stability and service life of the telescopic member 4 and the sliding member 2.

[0056] Furthermore, in order to improve the transmission efficiency of the guide structure and realize linear transmission, the distal end of the sliding member 2 is a tapered structure, the tapered structure is a cone, the first guide surface 21 is a tapered surface, and the first end 41 of the telescopic member 4 is provided with a second guide surface 43, and the second guide surface 43 is at least partially in contact with the first guide surface 21. When the transmission is performed through the tapered surface, since the tapered surface has a regular shape and a smooth surface, linear transmission can be realized when it is in contact with the telescopic member 4. Moreover, when the second guide surface 43 is completely in contact with the first guide surface 21, the forces between the two can be better balanced.

[0057] Ginseng Figures 3 to 6 As shown, the driving assembly 3 in this embodiment also includes a sleeve 31 and a push rod 33. The distal end of the sleeve 31 abuts against the proximal end of the sliding member 2, the distal end of the push rod 33 abuts against the proximal end of the sleeve 31, and the proximal end of the push rod 33 is located outside the sleeve 1. The setting of the push rod 33 facilitates the operator to drive the sliding member 2 from the outside of the sleeve 1.

[0058] Furthermore, a first stopper 22 is formed on the outer side of the distal end of the slider 2, and a second stopper 311 is provided on the outer side of the sleeve 31. A first elastic member 34 is installed between the first stopper 22 and the second stopper 311 and is sleeved on the outer side of the slider 2 and the sleeve 31. The first elastic member 34 can be a spring or other elastically deformable member. The first stopper 22 can be a ring sheet extending radially outward from the outer side of the slider 2. The ring sheet can be integrally formed with the conical structure at the distal end of the slider 2, or can be kept at a certain distance from the conical structure. Alternatively, the first stopper 22 can also be directly formed by the end face of the proximal end of the conical structure at the distal end of the slider 2. In this case, the end face of the proximal end of the conical structure needs to protrude radially outward from the main part of the slider 2. The second stopper 311 can also be a ring sheet extending radially outward from the outer side of the sleeve 31.

[0059] Reference Figures 3 to 8 As shown, the driving assembly 3 in this embodiment further includes a positioning cylinder 32 , which is at least sleeved on the proximal end of the sleeve 31 and the outside of the distal end of the push rod 33 , and the proximal end of the push rod 33 is located outside the positioning cylinder 32 .

[0060] Furthermore, a plurality of first positioning grooves 322 distributed along the circumferential direction and penetrating the wall of the positioning cylinder 32 are provided on the wall of the positioning cylinder 32, and the first positioning grooves 322 extend to the distal end of the positioning cylinder 32, a plurality of first positioning members 312 distributed along the circumferential direction are provided on the outside of the proximal end of the sleeve 31, a plurality of second positioning members 331 distributed along the circumferential direction are provided on the outside of the distal end of the push rod 33, and a third guide surface 313 and a fourth guide surface 332 abutting against each other are respectively provided at the proximal end of the first positioning member 312 and the distal end of the second positioning member 331.

[0061] Furthermore, the driving assembly 3 in this embodiment has two working states. Specifically, in the first state, the first positioning member 312 and the second positioning member 331 are both located in the first positioning groove 322, and the proximal end of the first positioning member 312 abuts against the distal end of the second positioning member 331. In the second state, the second positioning member 331 is at least partially located in the first positioning groove 322. The third guide surface 313 and the fourth guide surface 332 are used to drive the sleeve 31 to rotate when the first positioning member 312 is located outside the first positioning groove 322, so that the first positioning member 312 is located outside the first positioning groove 322.

[0062] Ginseng Figure 7 , Figure 8 As shown, in order to fix the position of the first positioning member 312 in the second state, so that the first positioning member 312 can provide a stable thrust to the telescopic member 4 and can be moved back into the first positioning groove 322, a clamping structure that can clamp the first positioning member 312 can be provided at the distal end of the positioning cylinder 32, and the clamping structure can adopt the following scheme.

[0063] A fifth guide surface 324 , a sixth guide surface 325 , and a stop surface 326 connecting the fifth guide surface 324 and the sixth guide surface 325 are provided on the end surface between two adjacent first positioning grooves 322 in the positioning tube 32 .

[0064] Specifically, the first side of the fifth guide surface 324 is adjacent to one first positioning groove 322, and the distance between the second side and the proximal end of the positioning cylinder 32 is smaller than the distance between the first side and the proximal end of the positioning cylinder 32. The second side of the sixth guide surface 325 is adjacent to another first positioning groove 322, and the distance between the first side and the proximal end of the positioning cylinder 32 is larger than the distance between the second side and the proximal end of the positioning cylinder 32. The first side of the stop surface 326 is connected to the second side of the fifth guide surface 324, and the second side is connected to the first side of the sixth guide surface 325, and the distance between the first side of the stop surface 326 and the proximal end of the positioning cylinder 32 is smaller than the distance between the second side of the stop surface 326 and the proximal end of the positioning cylinder 32.

[0065] When the first positioning member 312 is completely pushed out of the first positioning groove 322 by the second positioning member 331, since the first elastic member 34 has a tendency to rebound, the first elastic member 34 has a tendency to drive the first positioning member 312 to move toward the proximal end. However, since the first positioning member 312 is supported by the second positioning member 331 and cannot move toward the proximal end, the first positioning member 312 begins to slide along the fourth guide surface 332 to the fifth guide surface 324 under the drive of the first elastic member 34. When the first positioning member 312 slides to the stop surface 326, it is intercepted by the stop surface 326 and cannot move further.

[0066] When there is no need to provide thrust to the telescopic member 4 , the first positioning member 312 needs to be moved back into the first positioning groove 322 , that is, the first positioning member 312 needs to be pushed onto the sixth guide surface 325 so that it slides into another first positioning groove 322 along the sixth guide surface 325 .

[0067] In order to achieve the above effect, in this embodiment, a plurality of second positioning grooves 323 distributed circumferentially and parallel to the axial direction of the positioning cylinder 32 are provided on the inner wall of the positioning cylinder 32, and the second positioning grooves 323 at least partially extend to the fifth guide surface 324 at the distal end of the positioning cylinder 32. A plurality of third positioning members 333 distributed circumferentially are provided on the outside of the distal end of the push rod 33, each third positioning member 333 is located between two adjacent second positioning members 331, and the third positioning member 333 is at least partially located in the second positioning groove 323, and a seventh guide surface 334 with the same inclination direction as the fourth guide surface 332 is provided at the distal end of the third positioning member 333.

[0068] When it is necessary to move the first positioning member 312 into the first positioning groove 322 again, the push rod 33 can be pushed again so that the third positioning member 333 pushes the first positioning member 312 to move toward the distal end first. When the first positioning member 312 is completely separated from the stop surface 326, under the guidance of the seventh guide surface 334, the first positioning member 312 slides to the sixth guide surface 325, and then slides along the sixth guide surface 325 and falls into another first positioning groove 322.

[0069] Furthermore, in order to make the stop surface 326 fit the first positioning member 312 as closely as possible and balance the forces on the contact surfaces of the two, the stop surface 326 can be set as a vertical surface. Specifically, the stop surface 326 is perpendicular to the end surface of the proximal end of the positioning cylinder 32. Of course, the stop surface 326 can also limit the first positioning member 312 by tilting a certain direction toward the fifth guide surface 324.

[0070] Furthermore, in order to make the inner sides of the second positioning member 331 and the third positioning member 333 both fit with the outer side of the proximal end of the sleeve 31, prevent the sleeve 31 from shaking when the push rod 33 pushes the sleeve 31, and improve the stability of the abutment between the sleeve 31 and the push rod 33, the depth of the second positioning groove 323 is less than the depth of the first positioning groove 322, and the thickness of the third positioning member 333 is less than the thickness of the second positioning member 331. In this way, the inner curvature of the second positioning member 331 and the third positioning member 333 can be kept consistent, and can fit with the outer side of the proximal end of the sleeve 31 at the same time.

[0071] Ginseng Figure 2 , Figure 3 As shown, a plurality of fixing rings 321 are disposed on the outer side of the positioning tube, a plurality of mounting portions 12 are disposed in the sleeve 1 , and the positioning tube is fixedly mounted on the mounting portions 12 in the sleeve 1 through the fixing rings 321 .

[0072] Ginseng Figure 1 As shown, a support ring 13 is provided on the outer side of the sleeve 1. When the proximal end of the sleeve 1 is inserted into a component, the support ring 13 can abut against the outer surface of the component to support and limit the sleeve 1 and prevent the sleeve 1 from directly passing through the hole on the component.

[0073] Embodiment 2:

[0074] Figures 10 to 12 As shown, the quick-change system in this embodiment includes a mounting frame 5 and a quick-change structure. The quick-change structure is exactly the same as that in Embodiment 1 and will not be described in detail here.

[0075] The mounting frame 5 in this embodiment includes a first mounting plate 51 , which is provided with a mounting hole 511 . The distal end of the quick-change structure passes through the mounting hole 511 and extends out of the opening 11 by driving the telescopic member 4 to be fixedly mounted on the first mounting plate 51 .

[0076] Further, see Figures 10 to 12 As shown, a limiting assembly 7 located inside or outside the mounting hole 511 is fixedly mounted on the first mounting plate 51. The limiting assembly 7 includes a limiting ring 71 and a plurality of spring pieces 72. The spring pieces 72 are mounted on the inner wall of the limiting ring 71. When the distal end of the quick-change structure passes through the mounting hole 511, the spring pieces 72 correspond to the telescopic members 4 in the quick-change structure. When the telescopic member 4 extends out of the opening 11, it can squeeze the spring piece 72 and abut against the spring piece 72. When the sliding member 2 moves toward the proximal end and no longer pushes the telescopic member 4, the spring piece 72 recovers its elasticity and bounces the telescopic member 4 back into the opening 11, so that the first end 41 of the telescopic member 4 abuts against the distal end of the sliding member 2 again.

[0077] The mounting frame 5 in this embodiment also includes a second mounting plate 52 fixedly mounted and arranged opposite to the first mounting plate 51, and a third mounting plate 53 connecting the first mounting plate 51 and the second mounting plate 52. A guide column 61 arranged opposite to the mounting hole 511 is fixedly mounted on the second mounting plate 52. A guide ring 62 is sleeved on the outside of the guide column 61. A second elastic member 63 located between the guide ring 62 and the second mounting plate 52 is sleeved on the outside of the guide column 61. The second elastic member 63 can be a spring or other elastically deformable member. The diameter of the guide column 61 is less than or equal to the inner diameter of the far end of the sleeve 1. When the sleeve 1 is inserted into the mounting hole 511, the guide column 61 and the guide ring 62 can guide the sleeve 1. Moreover, when the mounting frame 5 is removed, the second elastic member 63 can also provide a certain thrust, so that the mounting frame 5 can quickly detach from the quick-change structure.

[0078] It can be seen from the technical solutions of the above embodiments that the utility model has the following beneficial effects:

[0079] The quick-change structure and quick-change system in the utility model have simple structures and are easy to operate. They can be applied to the fixing and disassembly of energy storage components and boxes, thus improving the disassembly and assembly efficiency of energy storage components. Bolts and supporting equipment are not required, thus reducing structural costs.
