DETAILED DESCRIPTION

[0100] 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 with reference to the accompanying drawings.

[0101] In the following description, specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0102] Example 1

[0103] like Figure 1 and Figure 2 As shown, the self-locking lunar base of the present invention includes a shock absorbing mechanism and a cabin mechanism, wherein the shock absorbing mechanism is located below the cabin mechanism, and the shock absorbing mechanism and the cabin mechanism are connected by a connecting mechanism, wherein the cabin mechanism in this embodiment is a cylindrical cabin mechanism. In addition to supporting the lunar base, the shock absorbing mechanism also plays a role in shock absorption.

[0104] like Figure 2 As shown, the shock absorbing mechanism includes a limit frame 1, and a hollow cavity is provided inside the limit frame 1. In this embodiment, the limit frame 1 is a rectangular parallelepiped, and a rectangular parallelepiped cavity is provided inside the limit frame 1. Preferably, the limit frame 1 is a cube, and the cavity inside it is in the shape of a cube. Several shock absorbing layers are provided in the groove in the limit frame 1 from top to bottom.

[0105] In the present embodiment, four shock-absorbing layers are arranged from top to bottom in the limit frame 1, namely the first shock-absorbing layer, the second shock-absorbing layer, the third shock-absorbing layer and the fourth shock-absorbing layer. The first shock-absorbing layer is composed of the first splicing plate, the second splicing plate, and the rolling balls between the first splicing plate and the second splicing plate. The second shock-absorbing layer is composed of the second splicing plate, the third splicing plate, and the rolling balls between the second splicing plate and the third splicing plate. The third shock-absorbing layer is composed of the third splicing plate, the fourth splicing plate, and the rolling balls between the third splicing plate and the fourth splicing plate. The fourth shock-absorbing layer is composed of the fourth splicing plate, the limit frame bottom plate, and the rolling balls between the fourth splicing plate and the limit frame bottom plate. In the present embodiment, the first splicing plate, the second splicing plate, the third splicing plate and the fourth splicing plate are preferably square plates.

[0106] like Fig.19 As shown, the bottom surface of the fourth splicing plate 3 is provided with a plurality of fourth splicing plate bottom surface grooves 301, the angle between the fourth splicing plate bottom surface grooves and the splicing plate side is 45°, a fourth rolling ball channel is formed between the fourth splicing plate bottom surface grooves and the bottom plate of the limiting frame 1, the angle between the fourth rolling ball channel and the splicing plate side is 45°, and the rolling ball 2 is placed in the fourth rolling ball channel. The fourth rolling ball channel formed between the limiting frame 1 and the fourth splicing plate 3 achieves a shock absorption effect in two directions along the fourth rolling ball channel.

[0107] like Fig.18 As shown, the top surface of the fourth splicing plate 3 is evenly spaced with a plurality of fourth splicing plate top surface grooves 302, the angle between the fourth splicing plate top surface grooves 302 and the side of the limiting frame is 45°, and the fourth splicing plate top surface grooves 302 and the fourth splicing plate bottom surface grooves 301 are vertically arranged. Fig.17 As shown, a plurality of third splicing plate bottom surface grooves 401 are provided on the bottom surface of the third splicing plate 4, and the third splicing plate bottom surface grooves 401 and the fourth splicing plate top surface grooves 302 have the same inclination direction, and the third splicing plate bottom surface grooves 401 are located directly above the fourth splicing plate top surface grooves 302, and the third splicing plate bottom surface grooves 401 and the fourth splicing plate top surface grooves 302 form a plurality of third rolling ball channels, and the angle between the third rolling ball channel and the side of the splicing plate is 45°, and the third rolling ball channel and the fourth rolling ball channel are perpendicular to each other, and the rolling ball is placed in the third rolling ball channel. The third rolling ball channel formed between the fourth splicing plate 3 and the third splicing plate 4 achieves a shock absorption effect in two directions along the third rolling ball channel.

[0108] like Fig.16 As shown, the top surface of the third splicing plate 4 is evenly spaced with a plurality of third splicing plate top surface grooves 402, and the third splicing plate top surface grooves 402 are arranged along the width direction of the limiting frame. Fig.15As shown, a plurality of second splicing plate bottom surface grooves 501 are provided on the bottom surface of the corresponding second splicing plate 5, the second splicing plate bottom surface grooves 501 are arranged along the width direction of the limit frame, and the second splicing plate bottom surface grooves 501 are located directly above the third splicing plate top surface grooves 402, the second splicing plate surface grooves 501 and the third splicing plate top surface grooves 402 constitute a plurality of second rolling ball channels, the second rolling ball channels are arranged along the width direction of the limit frame, and the rolling balls 2 are placed in the second rolling ball channels. The second rolling ball channels formed between the third splicing plate 4 and the second splicing plate 5 achieve a shock absorbing effect in two directions along the second rolling ball channels.

[0109] like Fig.14 As shown, the top surface of the second splicing plate 5 is evenly spaced with a plurality of second splicing plate top surface grooves 502, which are arranged along the length direction of the limiting frame, so the second splicing plate top surface grooves 502 and the second splicing plate bottom surface grooves 501 are perpendicular to each other. Fig.13 As shown, the corresponding first splicing plate 6 is provided with several first splicing plate bottom surface grooves 601, which are arranged along the length direction of the limit frame, and the first splicing plate bottom surface grooves 601 are located directly above the second splicing plate top surface grooves 502, and the first splicing plate bottom surface grooves 601 and the second splicing plate top surface grooves 502 constitute several first rolling ball channels, which are arranged along the length direction of the limit frame, and the first rolling ball channel and the second rolling ball channel are arranged vertically. The rolling ball 2 is placed in the first rolling ball channel. Through the first rolling ball channel formed between the first splicing plate 6 and the second splicing plate 5, the shock absorption effect in two directions along the first rolling ball channel is achieved.

[0110] When a moonquake occurs, the vibration is first transmitted to the limit frame, and then to the cylindrical cabin mechanism through the shock-absorbing layers arranged from bottom to top. During the vibration transmission process, the rolling of the ball in the ball channel can evenly offset the vibration energy in all directions, achieving a good shock-absorbing effect. Through the four shock-absorbing layers in this embodiment, the shock-absorbing effect of the shock-absorbing mechanism described in this application in eight directions is achieved, so that the lunar base has a good shock-absorbing effect and can better adapt to the lunar environment.

[0111] The second splicing plate 5, the third splicing plate 4 and the fourth splicing plate 3 in the present application are formed by splicing splicing blocks. In this embodiment, the splicing blocks are square, and the splicing plates formed by splicing splicing blocks are also preferably square plates. In this embodiment, the splicing structure of the second splicing plate 5 is described in detail.

[0112] like Fig. 20As shown, the splicing block 14 is a small block with a square cross section. The splicing block 14 has four sides of equal length. Two adjacent sides are provided with dovetail tenons 1401, and the other two adjacent sides are correspondingly provided with dovetail grooves 1402. The dovetail tenons 1401 are inserted into the dovetail grooves 1402 of the adjacent splicing blocks, thereby realizing the connection between the two adjacent splicing blocks. Preferably, the dovetail tenons and dovetail grooves in this embodiment are both arranged in the middle of the side of the splicing block.

[0113] In this embodiment, a plug hole 1403 is provided at the middle position of the splicing block 14 at a distance of 1 / 4 of the side length of the side with the dovetail tenon, and the connection between the adjacent upper and lower splicing boards can be achieved by means of a plug pin 1404 provided in the plug hole. In this application, the position of the plug hole 1403 is not limited to this, as long as the position of the plug holes on all splicing blocks constituting the same splicing board is ensured to be the same.

[0114] The splicing board in the present application includes several upper and lower splicing layers, and the splicing layers are connected by pins. The splicing board in this embodiment is connected by three upper and lower splicing layers. First, a first splicing layer is formed by splicing several splicing blocks. Then, a second splicing layer is formed by splicing several splicing blocks together. The second splicing layer is located above the first splicing layer. The splicing blocks between the adjacent upper and lower splicing layers are arranged in opposite directions, and the sockets between the adjacent upper and lower splicing layers are arranged correspondingly: Fig.21 As shown, a dovetail tenon is provided on one side of the splicing blocks constituting the first splicing layer, and a dovetail groove is provided on the same side of the splicing blocks constituting the second splicing layer. Finally, a third splicing layer is formed by splicing a plurality of splicing plates together, and the third splicing layer is located above the second splicing layer. The splicing blocks constituting the third splicing layer are arranged opposite to the splicing blocks constituting the second splicing layer, so the splicing blocks constituting the third splicing layer are arranged in the same direction as the splicing blocks constituting the first splicing layer, and the splicing blocks constituting the third splicing layer are located directly above the splicing blocks constituting the first splicing layer, as shown in FIG. Fig. 22 At the same time, the top surface of the splicing block of the third splicing layer is provided with a groove, and the grooves on two adjacent splicing blocks are interconnected, thereby forming a groove 502 on the top surface of the second splicing plate.

[0115] The sockets on the corresponding splicing blocks of the upper and lower splicing layers are connected to each other, and a plug is provided through the socket to realize the connection between the upper and lower splicing layers. Fig.24 As shown, so as to form a complete second splicing plate.

[0116] The splicing structure of the third splicing plate 4 and the fourth splicing plate 3 is exactly the same as that of the second splicing plate 5. The difference from the second splicing plate is that the direction of the grooves of the top splicing blocks of the third splicing plate and the fourth splicing plate is different from that of the second splicing plate. In the present application, a splicing plate can be formed by plugging together several identical splicing blocks and latches, which greatly reduces the types of components constituting the splicing plate, so as to realize the standardization and modular design of the splicing plate components.

[0117] The cylindrical cabin mechanism in this embodiment includes a cylindrical cabin body, an inflatable cabin 11, a front cabin door 9 and a rear cabin door 10. The front end of the cylindrical cabin body is provided with the front cabin door 9, and the rear end of the cylindrical cabin body 10 is provided with the rear cabin door 10. The cylindrical cabin body, the front cabin door 9 and the rear cabin door 10 form a cylindrical cavity, and the inflatable cabin 11 is fixedly arranged in the cavity, and the front end of the inflatable cabin 11 is connected to the front cabin door 9.

[0118] In this embodiment, the cylindrical cabin body includes an inner and outer covering layer, which are respectively formed by inserting a plurality of mortise and tenon bricks 12, and the inner and outer covering layers are fixedly connected by mortise and tenon connection. That is, the inner covering layer 15 and the outer covering layer 16 are respectively inserted by mortise and tenon bricks 12, and then the inner covering layer 15 and the outer covering layer 16 are connected by mortise and tenon, so as to form a complete cylindrical cabin body. Figure 6 shown.

[0119] The plug-in method of the inner and outer covering layers is exactly the same. In this embodiment, the plug-in structure of the inner covering layer is specifically described. The inner covering layer includes an array of mortise and tenon plug-in rings arranged in sequence along the axial direction of the cabin body. The mortise and tenon plug-in rings are in a closed circular ring shape, and adjacent mortise and tenon plug-in rings are fixedly connected by plugging. In this embodiment, each group of mortise and tenon plug-in rings is formed by plugging ten mortise and tenon bricks 12 located on the same circumferential surface. The central angle of the mortise and tenon bricks is 36°.

[0120] like Figure 7 and Figure 8As shown, the mortise and tenon brick 12 includes an arc-shaped brick body 1201, and the brick body 1201 has four arc-shaped side surfaces and two planes located at the ends. The arc-shaped side surfaces of the mortise and tenon brick include a front arc surface 1202, a rear arc surface 1203, an inner arc surface 1204 and an outer arc surface 1205, wherein the front arc surface 1202 is a side surface facing the front door, and the rear arc surface 1203 is a side surface facing the rear door. The front arc surface 1202 is provided with an arc-shaped tenon groove 1207, and the corresponding rear arc surface 1203 is provided with an arc-shaped tenon 1206, and the arc-shaped tenon 1206 can be fixedly inserted in the arc-shaped tenon groove 1207 of the adjacent mortise and tenon brick. The mortise and tenon connection between the mortise and tenon brick block and the mortise and tenon brick block in front of it, as well as the fixed connection between the mortise and tenon brick block and the front hatch in front of it are realized by the arc-shaped tenon groove 1207 on the front arc surface 1202; the mortise and tenon connection between the mortise and tenon brick block and the mortise and tenon brick block behind it, as well as the fixed connection between the mortise and tenon brick block and the rear hatch behind it are realized by the arc-shaped tenon head 1206 on the rear arc surface 1203.

[0122] A tenon 1208 is provided at the center of one end plane of the mortise and tenon brick, and a tenon groove 1209 is provided at the center of the other end plane of the corresponding mortise and tenon brick. The tenon 1208 can be fixedly inserted into the tenon groove 1209 of the adjacent mortise and tenon brick.

[0123] The structure of the mortise and tenon bricks in the present application is symmetrical, realizing the standardized and modular structural design of the mortise and tenon bricks. There is no need to identify their direction during actual use, and they can be plugged and fixed in the same direction, making the plug-in and fixation process of the entire cylindrical cabin very convenient, and facilitating the construction of the cylindrical cabin on the moon.

[0124] In the present application, the outer covering layer and the inner covering layer are connected in the same manner, the only difference is that the radius of the mortise and tenon bricks constituting the outer covering layer is larger than the radius of the mortise and tenon bricks constituting the inner covering layer. The mortise and tenon bricks of the outer covering layer and the mortise and tenon bricks of the inner covering layer are connected in a mortise and tenon manner.

[0125] like Fig. 9 As shown, two plug-in protrusions 901 are provided on the side of the front hatch 9 facing the cylindrical cabin body, and the two plug-in protrusions 901 are respectively fixedly plugged into the arc-shaped tenon grooves 1207 on the mortise and tenon bricks 12 of the inner and outer covering layers, that is, the fixed connection between the cylindrical cabin body and the front hatch 9 is achieved through the plug-in protrusions 901 and the arc-shaped tenon grooves 1207. The side of the front hatch 9 away from the cylindrical cabin body is a plane. A center hole is provided in the center of the front hatch 9, and the connection between the front hatch 9 and the cylindrical cabin body is achieved through the circular hole. In this embodiment, in order to facilitate the manufacture and installation of the front hatch 9, the front hatch 9 is composed of two semicircular rings.

[0126] like Fig.10 As shown, two insertion grooves 1001 are provided on the side of the rear hatch 10 facing the cylindrical cabin body, and the arc-shaped tenons 1206 of the inner and outer cladding bricks 12 are respectively fixedly inserted in the two insertion grooves 1001, that is, the cylindrical cabin body and the rear hatch 10 are fixedly connected through the insertion grooves 1001 and the arc-shaped tenons 1206. The side of the rear hatch 10 away from the cylindrical cabin body is a plane. In this embodiment, in order to facilitate the manufacture and installation of the rear hatch 10, the rear hatch 10 is composed of two semicircular plates.

[0127] In the present application, the cylindrical cabin is not limited to the inner and outer two layers of coating in this embodiment, and may include more layers of coating. The shapes of the front door and the rear door are also not limited to the above. The arrangement and specific number of the plug-in protrusions or plug-in grooves on the front door and the rear door need to be determined according to the specific structure of the cylindrical cabin connected thereto. That is, when the side of the cylindrical cabin facing the front door is provided with an arc-shaped tenon groove, a corresponding number of plug-in protrusions need to be correspondingly arranged on the corresponding surface of the front door; at this time, the side of the cylindrical cabin facing the rear door is provided with an arc-shaped tenon, and a corresponding number of plug-in grooves need to be correspondingly arranged on the corresponding surface of the rear door.

[0128] like Fig.11As shown, the inflatable cabin 11 in this embodiment is cylindrical, and the inflatable cabin 11 is arranged in a cylindrical cavity surrounded by a cylindrical cabin body, a front cabin door and a rear cabin door.

A limit plate 1101 is provided at the front end of the inflatable cabin 11, and the limit plate 1101 is fixedly connected to the inflatable cabin through a fixed shaft 1102. The fixed shaft 1102 is arranged in the center hole 902 of the front cabin door, and the radius of the fixed shaft 1102 is smaller than the radius of the center hole 902; the radius of the limit plate 1101 is larger than the radius of the center hole 902. Therefore, through the above structure, the connection between the inflatable cabin 11 and the front cabin door 9 is realized. After the inflatable cabin 11 is filled with gas, the staff can complete their work on the moon in the inflatable cabin 11.

[0129] The shock absorbing mechanism and the cylindrical cabin mechanism are fixedly connected by a connecting mechanism. The connecting mechanism includes a base support 8 and top paving bricks 7.

The bottom surface of the basic support 8 facing the first splicing plate is a plane, and the plane is fixedly connected to the first splicing plate by plugging and fixing.

[0131] In this embodiment, two basic supports 8 are provided at the bottom of the cylindrical cabin, and the two basic supports 8 are symmetrically arranged on the bottom surface of the cylindrical cabin. Each basic support 8 includes two symmetrically arranged basic support blocks 803, and the two basic support blocks 803 are connected to form a basic support with a semicircular upper surface. A plurality of arc-shaped slots 801 are arranged at intervals on the arc surface of the basic support block 803 facing the cylindrical cabin, and the arc-shaped tenons 1206 on the mortise and tenon bricks are fixedly inserted into the arc-shaped slots 801, thereby realizing a fixed connection between the basic support 8 and the cylindrical cabin.

[0132] The bottom surface of the basic support block 803 is a mortise and tenon structure corresponding to the upper surface of the first splicing plate, and the basic support block 8 is fixedly connected to the first splicing plate 6 through the mortise and tenon connection.

[0133] The top surface of the first splicing plate 6 is paved with top paving bricks 7, and the bottom surface of the top skin bricks 7 is connected to the top surface of the first splicing plate 6 through mortise and tenon joints. After the top paving bricks 7 are laid, gaps are reserved on the top surface of the first splicing plate 6 for connection with the base support 8, and the base support 8 is fixedly connected to the first splicing plate 6 through these gaps.

[0134] In this embodiment, the first splicing plate 6 is formed by splicing a plurality of first splicing blocks, and the top paving bricks 7 are formed by splicing a plurality of paving splicing blocks. Since the splicing seams of the first splicing plate and the splicing seams of the top paving bricks 7 are staggered, when the first splicing plate 6 and the top paving bricks 7 are connected by mortise and tenon joints, the splicing and fixing between the first splicing blocks, the splicing and fixing between the paving splicing blocks, and the fixed connection between the first splicing plate 6 and the top paving bricks 7 can be achieved.
