[0001] The present disclosure relates to the technical field of telescopic matrices, and more particularly to a consumer-grade telescopic matrix based on additive manufacturing technology. Background Art

[0002] Existing telescopic matrix devices generally refer to telescopic matrices based on mechanical structure systems, and their components generally include telescopic column housings, lead screws, optical rods, fixators, etc. They have the disadvantages of large volume, heavy weight, many metal parts, complex structure, limited minimum height, long assembly time, inability to automate production, generally having baffles between single columns and single-column structures, and low assembly consistency accuracy, and are not suitable for potential consumer product scenarios such as wall-mounted telescopic matrix three-dimensional decorative panels, retail store telescopic matrix display stands, telescopic matrix board game chessboards, etc. These products have the characteristics of small volume, light weight, requiring environmentally friendly materials (such as all plastics), low product height, being able to be mass-produced automatically, simple assembly, no baffles between columns, and high assembly accuracy requirements. Summary of the Invention

[0003] The present disclosure provides a consumer-grade telescopic matrix based on additive manufacturing technology to solve one of the technical problems recognized by the inventors.

[0004] The present disclosure provides a consumer-grade telescopic matrix based on additive manufacturing technology, including a base. The base is provided with at least one through hole. A bushing is fixedly connected to the surface of the base around the through hole. A rotating rod is embedded inside the bushing. The top end of the rotating rod penetrates through the bushing and is fixedly connected to a rotating head. A male thread is fixedly connected to the outside of the rotating head. The bottom end of the rotating rod penetrates through the through hole. A telescopic column is sleeved outside the bushing. The telescopic column is provided with a female thread, and the male thread and the female thread are in mating connection.

[0005] Preferably, four guide rods are fixedly connected to the surface of the base around the bushing. Guide grooves are provided at positions corresponding to the guide rods on the telescopic column. The guide rods are embedded in the guide grooves and can move axially along the guide grooves.

[0006] Preferably, a driving head is fixedly connected to the bottom end of the rotating rod, and a rotating head groove is provided inside the driving head.

[0007] Preferably, the outside of the rotating rod is a polygonal thread structure.

[0008] Preferably, the outer diameters of the rotating head and the driving head gradually increase in a direction away from the rotating rod.

[0009] Preferably, the outside of the male thread is subjected to knurling treatment.

[0010] Preferably, the inside of the rotating rod is hollow.

[0011] Preferably, the guide rod is integrally formed and connected with the bushing and the base, and the guide groove is connected through the female thread.

[0012] Preferably, the height of the rotating head is less than 1 cm or within 25% of the effective telescopic length D, and the effective telescopic length is the sum of the heights of the rotating rod and the rotating head.

[0013] Preferably, the base, the bushing, and the rotating rod are all integrally formed by additive manufacturing technology.

[0014] The beneficial effects of the present disclosure mainly lie in that: in the present invention, through the design of a hollow bushing and four guide rods provided on the base, the rotating rod is nested in the bushing, and there is no need to set fixing parts at the top, greatly increasing the structural strength. At the same time, no thread structure can be seen during the use process, protecting the threads while improving the overall aesthetics;

[0015] In the present invention, there is no need for a baffle as a reinforcing rib structure between the telescopic columns, simplifying the structure and improving the aesthetics of the product;

[0016] And the whole is integrally manufactured by 3D printing. Only the telescopic columns need to be manually assembled, saving a large amount of manual assembly time, improving production efficiency, reducing labor intensity, without any metal connecting parts, reducing processing difficulty, and reducing the overall quality.

[0029] Embodiment

[0030] As Figures 1-5As shown in the figure, this embodiment provides a consumer-level telescopic matrix based on additive manufacturing technology, including a base 1. The base 1 is a main structure with a square cross-section. At least one through hole is distributed in a rectangular array on the base 1. The number of through holes can be set according to the number of telescopic units of the telescopic matrix and can be customized according to requirements. A bushing 2 is arranged around each through hole on the surface of the base 1. The bushing 2 is a closed circular ring structure without any gaps, and the bottom is communicated with the through hole. A rotating rod 3 is embedded inside the bushing 2. The top end of the rotating rod 3 penetrates through the bushing 2 and is integrally formed with a rotating head 4. A male thread 41 is integrally formed on the outside of the rotating head 4. A telescopic column 7 is sleeved outside the bushing 2. The telescopic column 7 is a rectangular cover structure, and an internal female thread 71 that cooperates with the male thread 41 is arranged inside the telescopic column 7. In this embodiment, the telescopic matrix is composed of multiple repeated units. One through hole is provided in the base 1 of a single unit, and correspondingly, there is one bushing 2, one rotating rod 3, and one telescopic column 7. To form a matrix with multiple units, only the single unit needs to be arrayed. The edges of the base 1 will be automatically coupled together to form an integrated structure through 3D printing, and structures such as the bushing 2, the rotating rod, and the telescopic column 7 can also be arrayed and replicated during 3D printing to be combined into a telescopic matrix. It can be understood that the matrix is formed by coupling the bases 1 of multiple individual telescopic units together to form a whole. In this embodiment, the cross-section of the base 1 of a single telescopic unit of the matrix is square, and the size can be in the range of 0.5 - 10 cm. Users can customize according to requirements.

[0031] Furthermore, four guide rods 6 are integrally formed and connected around the bushing 2 on the surface of the base 1. Guide grooves 72 are provided at positions corresponding to the guide rods 6 on the telescopic column 7. The guide rods 6 are embedded in the guide grooves 72 and can move back and forth along the direction of the guide grooves 72. Through the limit and guidance of the guide grooves 72 and the guide rods 6, the rotation of the telescopic column 7 can be restricted, enabling it to only move up and down and playing a guiding role.

[0032] Moreover, through the integrally formed base, guide rods, and bushing structure, the structural strength of the base can be greatly increased, so that the thickness of the base can be reduced to less than 1 cm.

[0033] Among them, a driving head 5 is integrally formed by 3D printing at the bottom end of the rotating rod 3. A turning head groove 51 is provided inside the driving head 5. By inserting a screwdriver head or a motor rotor head into the turning head groove 51, the driving head 5 is controlled to rotate, thereby driving the entire rotating rod 3 to rotate and realizing the control of the telescopic column 7. And each rotating rod 3 is controlled separately, enabling the separate control of each telescopic column 7.

[0034] Further, the outer side of the rotating rod 3 has a polygonal thread structure, which is beneficial to reducing the friction between the rotating rod 3 and the bushing 2, preventing the rotating rod 3 from wearing, improving the service life, and making the rotating rod 3 rotate more smoothly. In this embodiment, the outer side of the rotating rod 3 has a hexagonal thread structure. Similarly, it can also be set to a 3-8 deformed thread structure and designed according to user needs.

[0035] In one embodiment, the outer diameters of the rotating head 4 and the driving head 5 gradually increase in the direction away from the rotating rod 3. This structure is applicable to 3D printing technology production. The rotating rod 3 and the base 1 are deposited and stacked upward along the Z-axis direction during production and do not interfere with each other. The driving head 5 inclines inward during the printing process to form a nested structure at the bottom. After the rotating rod 3 passes through the bushing 2, it extends outward at an angle of 45 degrees to form the rotating head 4, so that the rotating rod 3 is nested in the bushing 2 and cannot be pulled out but retains the function of rotating inside. The overhang stacking technology unique to additive manufacturing technology is used here. When depositing outward at an angle, part of the material adheres to the existing material, while the other part of the material hangs in the air to achieve the manufacturing of an outward inclined structure at a certain angle.

[0036] Further, the outer side of the male thread 41 is knurled. This reduces the friction between the male thread 41 and the female thread 71 and improves the service life.

[0037] Further, the inside of the rotating rod 3 is hollow. The hollow structure of the rotating rod 3 can effectively reduce the overall weight and solve the problem of the heavy weight of the traditional telescopic matrix.

[0038] In one embodiment, the guide rod 6 is integrally formed and connected with the bushing 2 and the base 1, and the guide groove 72 is connected through the female thread 71. The bottom of the guide rod 6 is integrally formed with the base 1, and the side is integrally formed with the outer wall of the bushing 2, improving the overall structural strength of the base 1. The guide groove 72 is connected through the female thread 71, disconnecting the female thread 71. This design of the disconnected female thread 71 is not easy to process or is extremely costly in traditional mold design methods. Therefore, manufacturing it through additive technology has the advantage of reducing costs.

[0039] Further, the height of the rotating head 4 is less than 1 cm or within 25% of the effective telescopic length D, and the effective telescopic length is the sum of the heights of the rotating rod 3 and the rotating head 4. This can effectively reduce the overall height of the product and reduce the occupied area.

[0040] Further, the base 1, the bushing 2, and the rotating rod 3 are all integrally formed by additive manufacturing technology. The additive manufacturing technology can be 3D printing.

[0041] Working principle of the present invention: The base 1, the bushing 2, and the rotating rod 3 of the present invention are integrally formed by 3D printing technology, omitting the steps of manual assembly, greatly improving the production efficiency. When in use, insert a screwdriver head or a motor rotor head into the turning head groove 51, rotate the turning head groove 51, drive the rotating rod 3 and the rotating head 4 to rotate synchronously. When the rotating head 4 rotates, the telescopic column 7 is limited by the guide rod 6, so that it cannot rotate and can only move back and forth along the Z-axis direction, thereby realizing the telescoping of the telescopic column 7. Users can customize the telescopic matrix according to their needs. A single telescopic unit is replicated by arraying and then printed out by 3D printing. The outer wall of the base 1 is automatically coupled and adhered, without additional modeling operations, greatly saving labor costs.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, and are not intended to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
