Description

Technical Field

[0001] The present invention relates to the technical field of shoes and clothing, and in particular to a symmetrical lattice 3D printed running shoe with high buffering performance. Background Art

[0002] Shoes are garments worn on the feet to protect the feet and facilitate walking. Traditional shoes are made of leather, cloth, rubber and other materials. In modern times, most shoes are composed of a midsole made of foam material and an upper that wraps the foot and is sewn on the midsole. A layer of outsole is installed under the midsole to improve wear resistance and grip, and the shoes are tied to the user's feet with the strap system on the upper. They are light and durable.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: the existing shoes need to manufacture the midsole, outsole, upper, etc. of the shoes separately, and then connect the various parts of the shoes by gluing or stitching. In order to obtain sufficient upper support, it is often necessary to form the upper body through multiple layers of composite fabrics. The processing steps are numerous and the thickness of the upper is thick, which makes the comfort level poor. At the same time, it also makes the overall manufacturing process of the shoes more complicated and cumbersome. When wearing, the midsole is made of foamed material, so when providing higher torsional support, it is often harder and difficult to provide sufficient cushioning performance. When the midsole is softer after foaming, although it can provide sufficient cushioning performance, it is easy to deform and difficult to provide effective torsional support. Torsional support and cushioning cannot be achieved at the same time. Summary of the invention

[0004] The purpose of the present invention is to address the defects and shortcomings of the prior art and provide a symmetrical lattice 3D printed running shoe with few manufacturing processes, both support and cushioning properties, lightness, breathability and high cushioning performance.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a symmetrical lattice 3D printed running shoe with high cushioning performance, comprising a lattice midsole formed by 3D printing and a shoe upper body formed by 3D printing, the upper surface of the shoe upper body being provided with a shoe upper opening for inserting the foot, the lattice midsole comprising a midsole body composed of a plurality of 3D printed lattice bodies and a support plate arranged on the top surface of the midsole body, the support plate comprising an arc-shaped heel plate and a middle section plate integrally formed with one side of the heel plate on one side, a forefoot plate integrally formed on the other side of the middle section plate, the heel plate being provided with a stress groove penetrating the heel plate at a stress-bearing position on the lower surface of the heel of the foot, and a plurality of cushioning support blocks penetrating and embedded on the forefoot plate The lattice body includes a honeycomb-shaped side frame formed by 3D printing and a deformation cavity integrally formed in the side frame. The inner wall of the deformation cavity is 3D printed with four support tubes with evenly distributed gaps. The center of the inner cavity of the deformation cavity is provided with an inner core body whose outer wall and the outer walls of the four support tubes are bonded and fixed. The inner core body includes a cylindrical core shell and an L-shaped deformation frame made of soft plastic material arranged on the inner wall of the core shell. A cross-shaped shrinkage groove is formed through the core shell, and an elastic sheet is arranged in the shrinkage groove. The lattice midsole and the upper body are quickly formed through 3D printing, and the lattice body is used to provide deformation shock absorption, and the support plate is used to provide torsional support. The force groove and the buffer support block are used to buffer the front and rear palm force points.

[0006] A further improvement is that shoelaces are also threaded around the upper body, and a high-density layer is formed on the surface of the upper body at the position where the shoelaces are threaded around by 3D printing.

[0007] A further improvement is that a hot-melt adhesive layer is provided on the heel of the foot and on the edge of the forefoot of the shoe upper.

[0008] A further improvement is that: the upper body is provided with a plurality of high-density reinforced spokes which are integrally formed on the upper body by 3D printing.

[0009] A further improvement is that: the upper surface of the upper body is also sprayed with a lateral support layer made of hot-melt TPU material extending downward to the side wall of the lattice midsole.

[0010] A further improvement is that a grid-shaped reinforcing side piece is formed on the side wall of the middle section of the midsole body by 3D printing.

[0011] Further improvements are: a high-density edge reinforcement strip is formed on the edge of the top surface of the midsole body through 3D printing, a heel support frame with the same density as the edge reinforcement strip and integrated through 3D printing is formed on the top surface of the midsole body at the heel position, a number of high-density arc-shaped reinforcement ribs are formed on the side walls of the midsole body through 3D printing, a number of inclined straight high-density heel stabilizing brackets are formed on the side walls of the heel position of the midsole body through 3D printing, and a high-density outer bottom layer formed by 3D printing is also provided on the bottom surface of the midsole body.

[0012] A further improvement is that: a plurality of reinforcing ribs are integrally formed on the middle section plate, and a triangular hollow groove is formed through the middle section plate.

[0013] A further improvement is that a capsule-shaped hollow cavity is provided on the bottom surface of the midsole body, and a second long strip-shaped support plate is embedded on the top surface of the hollow cavity.

[0014] Further improvements are: the buffer support block includes an airbag body that penetrates and is embedded on the front palm plate, and an elastic side balloon arranged at the bottom of the inner wall of the airbag body; the top surface of the outer wall of the side balloon is provided with a silicone pedal column that passes through the top surface of the airbag body; the top surface of the pedal column is hemispherical; the top surface of the inner wall of the airbag body is provided with an upper push plate; the bottom surface of the upper push plate is connected to an upper push piston; the side wall of the side balloon is fixedly provided with a compressed air pipe that is connected to the side balloon; the inner wall of the compressed air pipe is in contact with and slidably connected to the outer wall of the bottom of the upper push piston; and elastic fiber threads are also provided between the upper and lower surfaces of the inner wall of the airbag body.

[0015] After adopting the above technical solution, the beneficial effects of the present invention are:

[0016] The present invention forms a lattice midsole and a shoe upper through 3D printing technology, and cooperates with a nesting installation step to quickly process and shape the entire shoe, thereby greatly reducing the production and processing steps and increasing the production speed.

[0017] The present invention uses 3D printing technology to form a shoe upper with air holes, and cooperates with a reinforcing component formed on the shoe upper using 3D printing technology with a different density from the shoe upper to ensure that the shoe upper remains light, thin and breathable while having a high supporting strength, making the shoe lighter and more breathable when worn and more comfortable to wear. At the same time, it can be formed only through 3D printing, without the need to stack multiple layers of fabrics, and production and processing are more convenient and faster.

[0018] The present invention uses 3D printing technology to form a midsole body formed by stacking multiple lattices. The lattice body is honeycomb-shaped and filled with an inner core and a support tube. Therefore, there is much deformable space inside, and it can deform quickly when squeezed. At the same time, it is light in weight. When stepping laterally, it is not easy to twist due to the lateral support of the inner core and the support tube. The support stability is further improved in conjunction with the support plate. While ensuring high support stability, the longitudinal pressure can be fully buffered. At the same time, it can be formed only through 3D printing, and production and processing are more convenient and faster.

[0019] The present invention embeds a buffer support block on the support plate. When light pedaling such as walking is performed, the buffer support block can be squeezed to produce slow deformation, thereby providing pressure buffering for the foot and improving the comfort when wearing. When heavy pedaling such as running is performed, the foot steps hard on the buffer support block, and the airbag body can be deformed to absorb the impact pressure of the foot. At the same time, rapid downward pressure causes the side balloon to deform rapidly, and then the gas is pressed into the air pressure tube to push up the piston, and then the deformed airbag body is supported by the push-up sheet, thereby providing higher support, thereby controlling the deformation of the airbag body, ensuring the comfort of light pedaling while ensuring stability during heavy pedaling, i.e., more intense exercise.

[0029] See also Figure 1-7As shown, the technical solution adopted in this specific embodiment is: a symmetrical lattice 3D printed running shoe with high cushioning performance, comprising a lattice midsole 2 formed by 3D printing and a shoe upper body 1 formed by 3D printing, the upper surface of the shoe upper body 1 is provided with a shoe upper opening 11 for inserting the foot, the lattice midsole 2 comprises a midsole body 21 composed of a plurality of 3D printed lattice bodies 211 and a support plate 212 arranged on the top surface of the midsole body 21, the support plate 212 comprises an arc-shaped heel plate 32 and a middle section plate 31 integrally formed with one side of the heel plate 32, the other side of the middle section plate 31 is integrally formed with a forefoot plate 33, the heel plate 32 is provided with a force groove penetrating the heel plate 32 at the force-bearing position on the lower surface of the heel of the foot 36, a plurality of buffer support blocks 37 are penetrated and embedded in the front palm plate 33, and the buffer support block 37 includes an air bag body 41 penetrated and embedded in the front palm plate 33 and an elastic side balloon 44 arranged at the bottom of the inner wall of the air bag body 41, and the top surface of the outer wall of the side balloon 44 is provided with a silicone pedal column 42 that penetrates the top surface of the air bag body 41, and the top surface of the pedal column 42 is hemispherical, and the top surface of the inner wall of the air bag body 41 is provided with an upper push piece 47, and the bottom surface of the upper push piece 47 is connected to the upper push piston 46, and the side wall of the side balloon 44 is fixedly provided with a compressed air pipe 45 connected to the side balloon 44, and the inner wall of the compressed air pipe 45 is in contact with the outer wall of the bottom of the upper push piston 46 and is slidably connected, and an elastic fiber thread 43 is also provided between the upper and lower surfaces of the inner wall of the air bag body 41. The lattice body 211 includes a honeycomb-shaped side frame 51 formed by 3D printing and a deformation cavity 52 integrally formed in the side frame 51. The inner wall of the deformation cavity 52 is 3D printed with four support tubes 53 with evenly distributed gaps. The center of the inner cavity of the deformation cavity 52 is provided with an inner core body 55 whose outer wall and the outer walls of the four support tubes 53 are bonded and fixed. The inner core body 55 includes a cylindrical core shell 552 and an L-shaped deformation frame 551 made of soft plastic material arranged on the inner wall of the core shell 552. A cross-shaped shrinkage groove 553 is formed through the core shell 552. An elastic sheet 555 is arranged in the shrinkage groove 553. The lattice midsole 2 and the upper body 1 are quickly formed by 3D printing, and the lattice body 211 is cooperated to provide deformation shock absorption. 212 provides torsional support, and cooperates with the force groove 36 and the buffer support block 37 to buffer the front and rear palm force points. When in use, the shapes of the lattice midsole 2 and the upper body 1 are preset by the 3D printer, and then the elastic plastic material powder is added into the 3D printer, and the lattice midsole 2 and the upper body 1 can be quickly formed by the 3D printer. After the lattice midsole 2 is printed, the support plate 212 can be embedded in the top surface of the midsole body 21 of the lattice midsole 2, and the buffer support block 37 can be embedded in the position of the front palm plate 33 of the support plate 212, and then the 3D printer is started again, and the upper body 1 is formed above the lattice midsole 2. At this time, the whole shoe can be quickly processed and formed, thereby greatly reducing the production and processing steps and increasing the production speed.The upper body 1 with ventilation holes is formed by 3D printing technology, so that the upper body 1 remains light and breathable. At the same time, the upper body 1 is formed by elastic plastic material, and has a high deformation ability. The foot can get a good wrapping feeling when wearing it. It is lighter and more breathable when worn with the ventilation holes, and the wearing comfort is higher. At the same time, it can be formed only by 3D printing, and there is no need to stack multiple layers of fabrics. The production and processing are more convenient and faster. During wearing, when the foot steps on the lattice midsole 2, the midsole body 21 of the lattice midsole 2 can be squeezed, thereby causing multiple lattice bodies 211 to deform. The lattice body 211 includes a honeycomb-shaped side frame 51, and the internal deformation The L-shaped cavity 52 can provide sufficient deformation space, and the inner core 55 and the support tube 53 are filled in the deformation cavity 52. ​​When squeezed, the side frame 51 can be deformed inward to absorb the impact pressure of the foot, and the inner core 55 is placed on the support tube 53 to collapse instantly, resulting in insufficient support. The core shell 552 of the inner core 55 can absorb the pressure from the support tube 53, and further disperse the pressure through the L-shaped deformation frame 551 made of soft plastic material, while squeezing the elastic sheet 555 and shrinking the shrinkage groove 553. In this way, while deforming to absorb the impact force of the foot, the impact force absorption speed is relatively slow, preventing the support force from being insufficient and causing instant collapse. The wearer can step on the support plate 212 lightly, such as walking, with his foot pressed on the support plate 212, and the stepping of the forefoot can squeeze the buffer support block 37, thereby causing the air bag body 41 to deform slowly, thereby providing pressure buffering for the foot and improving the comfort when wearing. Moderately, when performing heavy pedaling such as running, the foot steps hard on the buffer support block 37, and the airbag body 41 can be deformed to absorb the impact pressure of the foot, and at the same time, the pressure is quickly output to the pedal column 42, causing the side balloon 44 to be squeezed and deformed by the pedal column 42, and then the gas inside it is pressed into the compressed air pipe 45 and the upward push piston 46 is pushed up by the air pressure, and then the upward push piston 46 pushes the upward push sheet 47 upward, and the upward push 47 resists the deformed airbag body 41 to provide higher support, thereby controlling the deformation of the airbag body 41, while ensuring the comfort of light pedaling, and ensuring the stability during heavy pedaling, that is, more intense exercise;,

[0030] The shoe upper body 1 is also threaded with a shoelace 12, and a high-density layer 14 is formed on the surface of the shoe upper body 1 at the position where the shoelace 12 is threaded through 3D printing, which is conducive to better wrapping the shoe upper body 1 on the user's foot through the shoelace 12, and the high-density layer 14 is used to improve the durability of the shoe upper body 1 when it is pulled by the shoelace 12, so that it is not easy to be damaged when it is pulled by the shoelace;

[0031] The upper body 1 is provided with a hot-melt adhesive layer 13 at the heel position and the edge position of the forefoot, which is beneficial to improve the rigidity of the upper body 1 at the heel position, so that the heel is more stable when worn, and at the same time improve the strength of the upper body 1 at the forefoot position, effectively improving the anti-trampling ability;

[0032] The upper body 1 is provided with a plurality of high-density reinforced spokes 16 integrally formed on the upper body 1 by 3D printing, which is beneficial to improving the lateral support of the upper body 1, avoiding the phenomenon that the upper body 1 cannot cover the foot when pushing the ground laterally, and making the upper body 1 more lateral stable as a whole;

[0033] The upper surface of the upper body 1 is also sprayed with a lateral support layer 15 of hot-melt TPU material extending downward to the side wall of the lattice midsole 2, which is beneficial to further improve the lateral support of the upper body 1;

[0034] The middle side wall of the midsole body 21 is provided with a grid-shaped reinforcing side piece 23 by 3D printing, which is beneficial to improving the anti-torsion performance of the midsole body 21;

[0035] The edge of the top surface of the midsole body 21 is formed with a high-density edge reinforcement strip 27 through 3D printing, and the top surface of the midsole body 21 is located at the heel position and is formed by 3D printing with a heel support frame 28 with the same density as the edge reinforcement strip 27 and is integrally formed, and a plurality of high-density arc-shaped reinforcement plate ribs 24 are formed on the side wall of the midsole body 21 through 3D printing, and a plurality of inclined straight strip-shaped high-density heel stabilizing brackets 25 are formed on the side wall of the heel position of the midsole body 21 through 3D printing, and the bottom surface of the midsole body 21 is also provided with a high-density outer bottom layer 22 formed by 3D printing, which is beneficial to improve the midsole through the edge reinforcement strip 27. The strength of the connection between the body 21 and the upper body 1 prevents cracking at the connection and improves the service life. At the same time, the heel support frame 28 is used to further improve the stability of the heel when worn, and prevents the heel from tipping over. The reinforcing plate ribs 24 are used to limit the lateral deformation of the midsole body 21, so that the user has higher stability when performing lateral force movements. The heel stabilizing bracket 25 cooperates with the reinforcing plate ribs 24 to make the heel position of the midsole body 21 more stable, and it is less likely to collapse excessively and tip over when stepping on. The outer bottom layer 22 greatly improves the wear resistance of the midsole body 21, thereby extending the overall service life of the shoe.

[0036] The middle plate 31 is integrally formed with a plurality of reinforcing ribs 34, and the middle plate 31 is penetrated with a triangular hollow groove 35, which is conducive to making the middle plate 31 less likely to be twisted under the action of the reinforcing ribs 34 when being twisted, and the triangular hollow groove 35 is used to maintain stability while reducing the weight of the middle plate 31, making the shoe lighter;

[0037] The bottom surface of the midsole body 21 is provided with a capsule-shaped hollow cavity 214, and the top surface of the hollow cavity 214 is embedded with a long strip of the second support plate 213, which is beneficial to reduce the weight of the midsole body 21 and save production materials. The second support plate 213 ensures that there will be no strength problems after hollowing out.

[0038] Working principle of the present invention: When the present invention is used, the shapes of the lattice midsole 2 and the upper body 1 are preset by a 3D printer, and then the elastic plastic material powder is added into the 3D printer, so that the lattice midsole 2 and the upper body 1 can be quickly formed by the 3D printer. After the lattice midsole 2 is printed and formed, the support plate 212 can be embedded in the top surface of the midsole body 21 of the lattice midsole 2, and the buffer support block 37 can be embedded in the position of the forefoot plate 33 of the support plate 212, and then the 3D printer is started again, and the upper body 1 is formed above the lattice midsole 2. At this time, the whole shoe can be quickly processed and formed, thereby greatly reducing the production and processing steps and increasing the production speed. The upper body 1 with air permeable holes is formed by 3D printing technology, so that the upper body 1 remains light, thin and breathable. At the same time, the upper body 1 is formed by elastic plastic material. The upper body 1 has a high deformation ability. The foot can get a good wrapping feeling when wearing it. It is lighter and more breathable when worn with the ventilation holes, and the wearing comfort is higher. At the same time, it can be formed only by 3D printing, and there is no need to stack multiple layers of fabrics. The production and processing are more convenient and fast. During wearing, when the foot steps on the lattice midsole 2, the midsole body 21 of the lattice midsole 2 can be squeezed at this time, thereby causing multiple lattice bodies 211 to deform. The lattice body 211 includes a honeycomb-shaped side frame 51, and the internal deformation cavity 52 can provide sufficient deformation space. At the same time, the deformation cavity 52 is filled with an inner core 55 and a support tube 53. When squeezed The side frame 51 can be deformed inward to absorb the impact pressure on the foot, and the inner core 55 can be placed on the support tube 53 to prevent it from collapsing instantly and causing insufficient support. The core shell 552 of the inner core 55 can absorb the pressure from the support tube 53, and further disperse the pressure through the L-shaped deformation frame 551 made of soft plastic material, while squeezing the elastic sheet 555 and shrinking the shrinkage groove 553. Therefore, while deforming to absorb the impact force on the foot, the impact force absorption speed is relatively slow, preventing the support force from being insufficient and collapsing instantly, which affects the stability of the user's movement. At the same time, the weight is light, and when stepping horizontally, the lateral support of the inner core 55 and the support tube 53 makes it difficult to twist and roll, and cooperates with the support plate 212 to further The support stability is improved step by step. While ensuring high support stability, the longitudinal pressure can be fully buffered. At the same time, it can be formed only through 3D printing, and the production and processing are more convenient and fast. When the wearer performs light pedaling such as walking, the foot is squeezed on the support plate 212, and the stepping of the forefoot can squeeze the buffer support block 37, which in turn causes the airbag body 41 to slowly deform, thereby providing pressure buffering for the foot and improving the comfort when wearing. When performing heavy pedaling such as running, the foot steps hard on the buffer support block 37, which can be deformed through the airbag body 41 to absorb the impact pressure of the foot, and at the same time quickly presses down to quickly output the pressure to the pedal column 42, causing the side balloon 44 to be squeezed and quickly deformed by the pedal column 42.Then the gas inside is pressed into the compressed air pipe 45 and the upward push piston 46 is pushed upward by the air pressure, and then the upward push piston 46 pushes the upward push plate 47 upward, and the upward push plate 47 resists the deformed airbag body 41 to provide higher support, thereby controlling the deformation of the airbag body 41, ensuring the comfort of light pedaling while ensuring the stability during heavy pedaling, i.e. more intense exercise.
