[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0041] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on the positions shown in the accompanying drawings, or the positions or locations in which the inventive product is typically placed when in use. These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0043] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0044] In the prior art, ice skates include a shoe body, an ice skate and a blade holder. The ice skates include a blade and a blade tube. The blade is connected to the blade tube, and the shoe body is connected to the blade tube through the blade holder. The blade tube is the core component of the ice skates. It is required to be able to bear the load caused by high-speed movement and to minimize the resistance encountered during movement, thereby reducing the impact on the athlete's competitive level. The blade tube of the prior art is made by stamping and forging aluminum. Due to the limitations of the processing technology, the blade tube as a whole must include a metal material with a continuous structure, especially an aluminum alloy material, which results in excess material and unnecessary weight, and also limits the design of the blade tube's appearance. The blade tube is heavy and inconvenient to use, which has a great impact on the athlete's competitive level.

[0045] In view of this, the designer designed an ice skate blade tube that is light in weight, has high structural strength, is easy to use, and has little impact on the athlete's competitive level.

[0046] See also Figure 1 and Figure 2 In this embodiment, the ice skate blade tube includes a streamlined tube body 110, and the tube body 110 is provided with a blade groove 111 for installing a blade 120; a cavity 112 is provided inside the tube body 110, which is independent of the blade groove 111. Since the cavity 112 is provided inside the tube body 110, the cavity 112 is independent of the blade groove 111, that is, the cavity 112 is a closed chamber and is not connected to the blade groove 111. The design of the cavity 112 reduces the weight of the tube body 110, which is convenient for athletes to use and is not likely to affect the athletes' competitive level; and the cavity 112 is designed to be closed and independent of the blade groove 111, and the inner wall structure of the tube body 110 surrounding the cavity 112 is continuous, which is not likely to affect the structural strength of the tube body 110 itself.

[0047] In this embodiment, the tube body 110 has a streamlined structure and a length ranging from 400 mm to 460 mm. The outer surface of the tube body 110 includes a first flat surface and a second flat surface facing each other. The first flat surface is used for mounting the base, and the second flat surface is provided with a rectangular groove 111. The groove 111 extends to the first and second end surfaces of the tube body 110 at both ends along its length.

[0048] In this embodiment, the cross-sectional area of the tube body changes in gradient And G n The value range is (0-5.00); in this way, the streamlined structure of the tube body is reasonable and the wind resistance is small.

[0049] Among them, S n represents the cross-sectional area of the measuring point n, (S n+1 -S n ) represents the difference in cross-sectional area between adjacent measuring points, X n Indicates the distance from the measuring point n to the reference line, (X n+1 -Xn ) represents the distance between adjacent measuring points; the cross-sectional area is the cross-sectional area perpendicular to the extension direction of the tube body 110, and the reference line is the center line of the tube body 110 in the length direction.

[0050] It should be understood that the tube body 110 is configured as a streamlined structure, which can reduce wind resistance and thus increase speed. Furthermore, the tube body 110 has two gradient sections. Specifically, the tube body 110 is divided into a first tube portion and a second tube portion with the middle position in the longitudinal direction of the tube body 110 as the dividing line, and the first tube portion and the second tube portion are both provided with gradient sections. The gradient section is the portion where the outer contour or cross-sectional area of the cross section of the tube body 110 changes with the position in the longitudinal direction of the tube body 110. In this embodiment, the cross-sectional area of the tube body 110 is used as an example for explanation. The cross-sectional area of the gradient section gradually decreases in the direction from the middle of the tube body 110 to the end of the tube body 110, and the gradient G of the cross-sectional area change of the tube body 110 in the gradient section is 0. n The range is set to (0.03-3) mm 2 / mm, for example, the ratio of the cross-sectional area of the tube body 110 increasing with distance is set to 0.03mm 2 / mm, 1.55mm 2 / mm or 3mm 2 / mm, etc. With such a design, the wind resistance of the tube body 110 is small, which has little impact on the competitive level of athletes.

[0051] Furthermore, the length of the single-side gradient section is not less than 40 mm, wherein the length of the gradient section is consistent with the length direction of the tube body 110 .

[0052] To understand the difference between the streamlined structure of the tube body of this embodiment and the tube body structure of a traditional ice skate, please refer to Figure 6 and Figure 7 ,in, Figure 6 is a schematic structural diagram of the tube body of this embodiment, Figure 7 The structure diagram of the tube body of the comparative example is shown in the form of a table, wherein Table 1 is the tube body of this embodiment, and Table 2 is the tube body of the comparative example, as follows:

[0053] Table 1

[0054]

[0055]

[0056] Table 2

[0057]

[0058] It can be seen from Tables 1 and 2 that the traditional tube body is streamlined only at the two ends. Among them, (X5-X9) and (X-5-X-9) in Table 1 represent two gradient sections of the tube body. Both gradient sections are streamlined, the overall structure of the tube body is more reasonable, and the wind resistance is small.

[0059] In this embodiment, it should be noted that the number of the cavities 112 provided in the tube body 110 can be one or more. Figure 3 When there is only one cavity 112, it is in the shape of an elongated strip, extending along the length of the tube body 110. The cross-sectional shape of the cavity 112 is similar to the cross-sectional outer contour of the tube body 110. That is, as the cross-sectional outer contour of the tube body 110 changes along its length, the cross-sectional shape of the cavity 112 also changes along the length of the tube body 110, and the change in the cross-sectional shape of the cavity 112 is consistent with the change in the cross-sectional outer contour of the tube body 110. It should be understood that two figures with equal corresponding angles and proportional corresponding sides are called similar figures, and the ratio of corresponding sides of similar figures is called the similarity ratio. When the similarity ratio is 1, the two similar figures are congruent. Obviously, because the cavity 112 is located inside the tube body 110, the similarity ratio between the two figures is not always equal to 1.

[0060] When there are multiple cavities 112, the cavities 112 are spaced apart along the length of the tube 110, and the centerlines of the cavities 112 are collinear with the centerline of the tube 110. Furthermore, the cross-sectional shape of each cavity 112 is similar to the cross-sectional outer contour of the tube 110.

[0061] In this embodiment, the cross-sectional shape of the cavity 112 is similar to the cross-sectional outer contour of the tube body 110 , so that the force on the tube body 110 is more uniform, the structural strength is high, and it is not easily damaged.

[0062] In this embodiment, the cross-sectional shape of the cavity 112 can be set to one or a combination of at least two of a circular, elliptical, teardrop-shaped, polygonal and curved shape, wherein the cross section is a plane perpendicular to the length direction of the tube body 110. At the same time, the cross-sectional area of the cavity 112 is set to a range of 0 mm 2 -190 mm 2 Obviously, the cross-sectional area of the cavity 112 is not zero.

[0063] See also Figure 2Furthermore, in order to improve the structural strength of the tube body 110 and enhance safety, a reinforcing rib structure 130 is provided both within the cavity 112 and on the outside of the tube body. For example, a reinforcing rib structure 130 can be provided within the cavity 112, and the reinforcing rib structure 130 is connected to the inner wall of the tube body constituting the cavity. The reinforcing rib structure 130 located within the cavity can be provided as a honeycomb structure, a rectangular array structure, or a ring array structure. The reinforcing rib structure located on the outside of the tube body can be welded to the tube body or integrally formed therewith. The reinforcing rib structure 130 located on the outside of the tube body can be provided as a geometric support structure. By providing the reinforcing rib structure 130, the structural strength of the tube body 110 can be enhanced. At the same time, the inner and outer reinforcing rib structures 130 can be set as an integrated structure with the tube body 110. For example, the reinforcing rib structure 130 can be combined with the tube body 110 as a whole by welding, or the reinforcing rib structure 130 can be combined with the tube body 110 as a whole by 3D printing. The combination of the reinforcing rib structure 130 and the tube body 110 is tighter, and the strength enhancement effect of the tube body 110 is better.

[0064] The ice skate blade tube provided in this embodiment has high structural strength while reducing the weight of the blade tube, meets usage requirements, is easy to use, and has little impact on the athlete's competitive level.

[0065] In this embodiment, the manufacturing process of the ice skate blade tube includes the following steps:

[0066] A knife tube model is established based on a traditional knife tube in the design software, wherein the design software may be ANSYS software.

[0067] Set the mechanical working parameters of the tool-barrel model;

[0068] Use mechanical working condition parameters to perform static analysis to obtain the optimal material distribution of the tool barrel;

[0069] The structure is designed based on the 100-degree arc of the skater's skates, and the functional complement design is performed based on the optimal material distribution to obtain the graphic data of the blade tube, so that the appearance of the blade tube is streamlined and has a hollow part;

[0070] The knife tube is manufactured using the graphic data; specifically, the image data can be imported into a 3D printing device, and the knife tube is printed using the 3D printing device. After printing, the knife tube is post-processed to finally obtain a finished product; the post-processing may include but is not limited to grinding, polishing or coating.

[0071] Alternatively, when printing the blade barrel using 3D printing equipment, the blade barrel support structure is first designed. Then, the 3D printer is activated to print the blade barrel using high-strength aluminum alloy powder. After printing, the blade barrel is separated from the support structure and the blade barrel is post-processed. Blade barrels made using high-strength aluminum alloy powder through 3D printing have a higher strength, longer service life, and greater safety.

[0072] See also Figure 4 and Figure 5 This embodiment also provides an ice skate comprising a shoe body 300, a blade holder 200, and an ice skate 100. The ice skate 100 comprises a blade 120 and the blade tube mentioned in the above embodiment. The shoe body is fixed to the tube 110 via the blade holder 200, and the blade 120 is engaged in the blade groove 111. It should be understood that the structures of the shoe body, blade holder 200, and blade 120 are not limited. The ice skate can be used in figure skating, ice hockey, speed skating, and other sports.

[0073] In this embodiment, optionally, two knife holders 200 are provided on the first plane of the tube body 110, and the two knife holders 200 are spaced apart in the length direction of the tube body 110. The shoe body is fixedly connected to the two knife holders 200 at the same time.

[0074] It should be noted that two bases 113 can be provided on the second plane of the tube body 110, and the two blade holders 200 are fixedly connected to the two bases 113, respectively. Optionally, each blade holder 200 is fixedly connected to the corresponding mounting portion via screws, bolts, pins, or rivets. It should be understood that the base 113 can be integrally formed with the tube body. In addition, by installing different numbers and different shapes of bases 113, it can be transformed into a corresponding short track speed skating or (long track) speed skating blade.

[0075] The ice skates provided in this embodiment are light in weight, well streamlined, experience little resistance during exercise, and have little impact on the athlete's competitive level.

[0076] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
