Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dot matrix structure, and in particular to an assemblable dot matrix structure based on planar cells. BACKGROUND

[0002] Lightweight is an eternal theme in the field of aerospace and automotive, and lighter weight means less energy consumption, longer endurance and lower emissions. Dot matrix structure, a kind of porous material containing periodic microstructure designed by imitating the dot matrix configuration in crystal material, has high specific strength and specific stiffness, and its internal pores make it have multifunctional potential, so it is an excellent lightweight multifunctional material.

[0003] Currently, the preparation of dot matrix structure is generally realized by additive manufacturing (3D printing). However, the cost, efficiency, precision, dimensional stability and other aspects of additive manufacturing cannot fully meet the requirements of civilian industry, especially the manufacturing of large lightweight structural parts will be limited by the size of additive manufacturing equipment, so the development cost is high and the application is limited.

[0004] Assembled dot matrix structure points out a new direction for batch preparation of dot matrix, but there are still many problems, for example, traditional bolt connection method has very high demand for installation node position, and the assembly space of bolt must be guaranteed, otherwise the production efficiency will be very low if assembled by hand; the complexity of unit cell configuration is limited, and too complex unit cell will also have to be prepared by additive manufacturing.

[0062] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are for the purpose of explanation of the present application, and are not to be understood as a limitation of the present application.

[0063] The following is combined Figures 1 to 17 This invention describes an assemblable lattice structure based on planar cells according to an embodiment of the present invention. This lattice structure is lightweight, can be rapidly fabricated, is suitable for mass production on production lines, and can be applied in aerospace, automotive and other fields.

[0064] like Figure 1 and Figure 9 As shown, the assemblable lattice structure based on planar cells according to an embodiment of the present invention is assembled from multiple octahedral lattice unit cells 1. Each octahedral lattice unit cell 1 is assembled from three independent mutually orthogonal planar cells 2. The three planar cells 2 are integrally formed parts of a planar quadrilateral surrounded by four rods.

[0065] In this embodiment of the invention, the assemblable lattice structure based on planar cells is assembled from multiple octahedral lattice unit cells 1. That is, the octahedral lattice unit cells 1 can be assembled with each other to form a lattice structure with a sufficiently large volume to meet usage requirements. Specifically, the assembly and connection methods between the octahedral lattice unit cells 1 can include snap-fit ​​connections, magnetic attraction, interference fit connections, or biomimetic joint connections, etc., making assembly simple, convenient, and fast, and resulting in high production efficiency.

[0066] like Figure 1 and Figure 9 As shown, each octahedral lattice unit cell 1 is assembled from three independent, mutually orthogonal planar unit cells 2. That is, the three planar unit cells 2 are independently fabricated, and after being assembled into an octahedral lattice unit cell 1, the three planar unit cells 2 are mutually orthogonal in pairs, thus forming a stable spatial structure. For example... Figures 1 to 2 and Figure 9 As shown, three planar cells 2 are distributed in planes a, b, and c, respectively, where planes a, b, and c are orthogonal to each other. Specifically, the planar cells 2 can be connected to form an octahedral lattice unit cell 1 through snap-fit ​​connections, magnetic attraction, interference fit connections, threaded connections, or biomimetic joint connections. The connection methods are simple and can achieve rapid connection.

[0067] like Figures 3 to 7 and Figures 10 to 14 As shown, the three planar cells 2 are integrally molded parts formed by four rods enclosing a planar quadrilateral. It can be understood that each planar cell 2 includes four rods forming a planar quadrilateral, and all four rods are located in the same plane; the planar cell 2 is an integrally molded part, meaning that it can be manufactured using integral molding processes, such as injection molding, engraving, and cutting—mature mass production processes that facilitate mass manufacturing.

[0068] According to the embodiment of the application, the minimum component structure is the planar cell 2, three independent planar cells 2 are connected in the cell in a mutually orthogonal manner to assemble an octahedral lattice unit cell 1, and then the octahedral lattice unit cells 1 are connected between cells to form the planar cell-based assemblable lattice structure of the embodiment of the application. The octahedral lattice unit cell 1 is a relatively complex lattice unit cell structure, which is formed by assembling without using additive manufacturing, and the size is not affected by the size of the additive manufacturing equipment, so that the complex microstructure material can be quickly prepared and batched and automatically produced. Since the planar cell 2 can be processed by one-piece molding, three planar cells 2 can be quickly assembled into an octahedral lattice unit cell 1, and multiple octahedral lattice unit cells 1 can be quickly assembled into a lattice structure, so that the assemblable lattice structure of the application can be batched and automatically produced on a large scale to meet the industrialization needs.

[0069] According to an embodiment of the application, the planar cell 2 is made of a material with high strength and light weight, such as metal or fiber composite material, which has good strength and meets the use needs in the fields of aerospace and automobiles.

[0070] As shown in Figure 1 , according to an embodiment of the application, the planar cell-based assemblable lattice structure is assembled by multiple octahedral lattice unit cells 1 in a buckle connection manner, which avoids the use of additional fasteners and the problem of limited installation space, and has simple installation operation, high assembly efficiency, and is suitable for production line batch production.

[0071] According to a further embodiment of the application, each octahedral lattice unit cell 1 is assembled by three planar cells 2 in a buckle connection manner (as shown in Figures 1 to 8 ) or a screw connection manner (not shown in the figure). The planar cells 2 are combined into the octahedral lattice unit cell 1 in the buckle connection manner or the screw connection manner, which has fast connection speed, simple installation operation, high assembly efficiency, and is suitable for production line batch production.

[0072] As shown in Figures 1 to 7 , according to a further embodiment of the application, in each octahedral lattice unit cell 1, the three planar cells 2 are a first planar cell 201, a second planar cell 202, and a third planar cell 203; as shown in Figure 2 , the first planar cell 201 is, for example, a planar cell 2 located in the plane a, the second planar cell 202 is, for example, a planar cell 2 located in the plane b, and the third planar cell 203 is, for example, a planar cell 2 located in the plane c.

[0073] As shown in Figure 3As shown, a set of diagonal positions of the first planar unit cell 201 are provided with first intracellular connecting clamping heads 2011 with the same assembly direction, and another set of diagonal positions of the first planar unit cell 201 are provided with second intracellular connecting clamping heads 2012 with the same assembly direction, the assembly direction of the first intracellular connecting clamping head 2011 and the assembly direction of the second intracellular connecting clamping head 2012 are perpendicular to each other; wherein the first intracellular connecting clamping head 2011 is used for clamping connection with the second planar unit cell 202, and the second intracellular connecting clamping head 2012 is used for clamping connection with the third planar unit cell 203.

[0074] As shown in the figure, Figure 4 As shown, a set of diagonal positions of the second planar unit cell 202 are provided with first intracellular connecting clamping seats 2021 corresponding to the clamping connection of the first intracellular connecting clamping head 2011, after the clamping connection of the first intracellular connecting clamping head 2011 and the first intracellular connecting clamping seat 2021, the relative position of the first planar unit cell 201 and the second planar unit cell 202 will be fixed and will not be displaced.

[0075] As shown in the figure, Figure 4 As shown, another set of diagonal positions of the second planar unit cell 202 are provided with third intracellular connecting clamping heads 2022 with the same assembly direction; the third intracellular connecting clamping head 2022 is used for clamping connection with the third planar unit cell 203, and the relative position of the second planar unit cell 202 and the third planar unit cell 203 is fixed.

[0076] As shown in the figure, Figure 6 As shown, the first intracellular connecting clamping head 2011 of the first planar unit cell 201 is inserted into the first intracellular connecting clamping seat 2021 of the second planar unit cell to form a first intermediate body, and the assembly direction of the second intracellular connecting clamping head 2012 and the third intracellular connecting clamping head 2022 of the first planar unit cell 201 of the first intermediate body is the same; in this way, when the third planar unit cell 203 is inserted into the first intermediate body, the second intracellular connecting clamping head 2012 and the third intracellular connecting clamping head 2022 can form a stable clamping structure with the third planar unit cell 203, the installation action is simple, and the assembly efficiency is high.

[0077] As shown in the figure, Figure 5 and Figure 7 As shown, a set of diagonal positions of the third planar unit cell 203 are provided with second intracellular connecting clamping seats 2031 corresponding to the clamping connection of the second intracellular connecting clamping head 2012, and another set of diagonal positions of the third planar unit cell 203 are provided with third intracellular connecting clamping seats 2032 corresponding to the clamping connection of the third intracellular connecting clamping head 2022, the second intracellular connecting clamping head 2012 of the first intermediate body is inserted into the second intracellular connecting clamping seat 2031 of the third planar unit cell 203, and the third intracellular connecting clamping head 2022 of the first intermediate body is inserted into the third intracellular connecting clamping seat 2032 of the third planar unit cell 203, thereby forming an octahedral lattice unit cell 1.

[0078] In the assembling process of the octahedral lattice cell 1 in the card fitting mode, as shown in Figure 6 and Figure 7 , first, the first planar cell 201 (i.e. the planar cell 2 in the plane a) is inserted into the first intracellular connecting card seat 2021 of the second planar cell 202 along the front-rear direction, so as to form a first intermediate body. When the first intermediate body is inserted, the assembling directions of the second intracellular connecting card head 2012 and the third intracellular connecting card head 2022 of the first intermediate body are the same; then the first intermediate body is moved along the up-down direction, so that the second intracellular connecting card head 2012 of the first intermediate body is correspondingly inserted into the second intracellular connecting card seat 2031 of the third planar cell 203, and the third intracellular connecting card head 2022 of the first intermediate body is correspondingly inserted into the third intracellular connecting card seat 2032 of the third planar cell 203, so as to obtain the octahedral lattice cell 1. The connecting process does not need additional connecting parts, the assembling mode is simple, easy to operate, and convenient for automatic assembling, so as to realize batch production.

[0079] In a specific example, as shown in Figures 3 to 7 , the intracellular connecting card head includes a pointed end portion, and when the intracellular connecting card head and the intracellular connecting card seat are inserted into each other, the pointed end portion of the intracellular connecting card head extends out of the end of the intracellular connecting card seat to limit and complete the fastening insertion.

[0080] According to a further embodiment of the present application, as shown in Figures 4 to 7 , the second planar cell 202 is provided with a group of intracellular connecting card heads 204 at a group of diagonal positions, the third planar cell 203 is provided with a group of intracellular connecting card heads 204 at another group of diagonal positions, and the third planar cell 203 is provided with a group of intracellular connecting card heads 204 at another group of diagonal positions; the assemblable lattice structure based on the planar cell further comprises a plurality of intercellular connecting buckling seats 205; and the plurality of octahedral lattice cells 1 are assembled into the assemblable lattice structure based on the planar cell through the buckling cooperation of the intracellular connecting card heads 204 and the intercellular connecting buckling seats 205. In the assembling process of the octahedral lattice cell 1 into the assemblable lattice structure based on the planar cell, the intracellular connecting card heads 204 and the intercellular connecting buckling seats 205 need to be kept in the same direction, so that the octahedral lattice cell 1 can be topologically formed into a block structure of any size along the front-rear, left-right and up-down directions, and finally a three-dimensional lattice structure with periodicity can be obtained, and a larger lattice part can be obtained through subsequent assembly.

[0081] In a specific example, as shown in Figures 4 to 7 , the intracellular connecting card head 204 includes two symmetrical pointed end structures which do not contact each other, as shown in Figure 8As shown, the inside of the intercellular connection buckle seat 205 is provided with a through slot for the two tip structures of the extracellular connection buckle head 204 to pass through, and the two sides of the through slot are bosses. When the two tip structures of the extracellular connection buckle head 204 are inserted into the through slot in the intercellular connection buckle seat 205, the two tip structures of the extracellular connection buckle head 204 will abut against the bosses inside the intercellular connection buckle seat 205 under the action of the elasticity, thereby limiting the relative movement between the installed extracellular connection buckle head 204 and the intercellular connection buckle seat 205. With this connection mechanism, the connection action is simple and fast.

[0082] According to one embodiment of the present application, as shown in Figure 9 The assemblable lattice structure based on planar cells is assembled by a plurality of octahedral lattice unit cells 1 in a magnetic attraction connection mode, and is also suitable for use in field emergency assembly and laying. That is, the octahedral lattice unit cells 1 can also be connected and assembled with each other in a magnetic attraction connection mode, such as assembly in the up-down direction, the left-right direction, or the front-back direction, so that the three-dimensional lattice structure with periodicity obtained by assembly can be used to obtain a larger assemblable lattice structure based on planar cells through subsequent assembly. The assemblable lattice structure based on planar cells is assembled in a magnetic attraction connection mode, and the assembly action is simple and convenient for automatic assembly. The assembly process can also realize self-positioning according to the setting position of the magnetic attraction component, which is beneficial to accurate assembly.

[0083] According to a further embodiment of the present application, as shown in Figure 9 Each octahedral lattice unit cell 1 is assembled by three planar cells 2 in a magnetic attraction connection mode. It can be understood that the planar cells 2 are assembled into octahedral lattice unit cells 1 in a magnetic attraction connection mode, and the assembly action is simple and convenient for automatic assembly. The assembly process can realize self-positioning according to the position setting of the magnetic attraction component, and can realize fast and accurate assembly. In addition, the magnetic components at the magnetic attraction connection positions in the planar cells 2 can be integrally processed by insert injection molding process, and batch production can be realized.

[0084] According to a further embodiment of the present application, as shown in Figure 2 and Figures 9 to 14 In each octahedral lattice unit cell 1, the three planar cells 2 are a fourth planar cell 206, a fifth planar cell 207, and a sixth planar cell 208, as shown in Figure 2 The fourth planar cell 206 is a planar cell 2 located in the a plane, the fifth planar cell 207 is a planar cell 2 located in the b plane, and the sixth planar cell 208 is a planar cell 2 located in the c plane.

[0085] As shown in Figure 10As shown, a set of diagonal positions of the fourth planar cell 206 are provided with the first intra-cell connecting magnetic head 2061 with the same direction and opposite polarity, and another set of diagonal positions of the fourth planar cell 206 are provided with the second intra-cell connecting magnetic head 2062 with the same direction and opposite polarity, and the direction of the first intra-cell connecting magnetic head 2061 is perpendicular to the direction of the second intra-cell connecting magnetic head 2062; wherein the first intra-cell connecting magnetic head 2061 is used for magnetic connection with the fifth planar cell 207, and the second intra-cell connecting magnetic head 2062 is used for magnetic connection with the sixth planar cell 208, since the fifth planar cell 207 and the sixth planar cell 208 are perpendicular to each other, the direction of the first intra-cell connecting magnetic head 2061 is perpendicular to the direction of the second intra-cell connecting magnetic head 2062.

[0086] As shown in the figure, Figure 11 a set of diagonal positions of the fifth planar cell 207 are provided with the third intra-cell connecting magnetic head 2071 corresponding to the first intra-cell connecting magnetic head 2061, and another set of diagonal positions of the fifth planar cell 207 are provided with the fourth intra-cell connecting magnetic head 2072 with the same direction; after the first intra-cell connecting magnetic head 2061 and the third intra-cell connecting magnetic head 2071 are magnetically attracted to each other, the relative position of the fourth planar cell 206 and the fifth planar cell 207 is fixed and cannot be displaced.

[0087] As shown in the figure, Figure 13 the first intra-cell connecting magnetic head 2061 of the fourth planar cell 206 is correspondingly magnetically connected with the third intra-cell connecting magnetic head 2071 of the fifth planar cell 207 to form a second intermediate body, and the direction of the second intra-cell connecting magnetic head 2062 of the fourth planar cell 206 and the direction of the fourth intra-cell connecting magnetic head 2072 of the fifth planar cell 207 are the same; in this way, when the sixth planar cell 208 moves to magnetically connect with the second intermediate body, the second intra-cell connecting magnetic head 2062 and the fourth intra-cell connecting magnetic head 2072 can both form a stable magnetic connection structure with the sixth planar cell 208, and the installation action is simple and the assembly efficiency is high.

[0088] As shown in the figure, Figure 12As shown in the drawings, the fifth intra-cell connecting magnetic head 2081 is arranged at the diagonal position of the sixth planar cell 208 corresponding to the second intra-cell connecting magnetic head 2062, and the sixth intra-cell connecting magnetic head 2082 is arranged at the other diagonal position of the sixth planar cell 208 corresponding to the fourth intra-cell connecting magnetic head 2072; the second intra-cell connecting magnetic head 2062 of the second intermediate body is connected to the fifth intra-cell connecting magnetic head 2081 of the sixth planar cell 208, and the fourth intra-cell connecting magnetic head 2072 of the intermediate body is connected to the sixth intra-cell connecting magnetic head 2082 of the sixth planar cell 208, thereby forming the octahedral lattice unit cell 1.

[0089] In the assembling process of the octahedral lattice unit cell 1, as shown in the drawings, Figure 13 and Figure 14 first, the fourth planar cell 206 (i.e., the planar cell 2 in the plane a) is connected to the third intra-cell connecting magnetic head 2071 of the fifth planar cell 207 in the front-rear direction to form the first intermediate body. Since the polarities of the first intra-cell connecting magnetic heads 2061 at the diagonal positions are opposite, the magnetic connection between the fourth planar cell 206 and the fifth planar cell 207 has only one mode, and after the magnetic connection is completed, the magnetic attraction surface of the second intra-cell connecting magnetic head 2062 faces the same direction as that of the fourth intra-cell connecting magnetic head 2072. Then, the second intermediate body is moved in the up-down direction in the drawings, and the second intra-cell connecting magnetic head 2062 and the fourth intra-cell connecting magnetic head 2072 of the second intermediate body are connected to the fifth intra-cell connecting magnetic head 2081 and the sixth intra-cell connecting magnetic head 2082, respectively, thereby obtaining the octahedral lattice unit cell 1. Since the intra-cell connecting magnetic heads have a large magnetic attraction force in the installation direction, no additional structure is needed to prevent the relative displacement between the two planar cells 2 to be installed.
