Smart glasses integrate multiple functional devices such as cameras, sensors, and displays to provide users with a convenient interactive experience.

[0003] Existing smart wearable products, such as glasses, typically feature temples assembled from an inner and outer shell, with a central cavity for mounting functional components. These temples are constructed from highly rigid materials. This structure offers certain advantages, such as effectively protecting internal components and improving the overall rigidity of the glasses. However, this structure and material selection also present challenges such as heavy and thick shells, low local elasticity, and increased overall weight. This can easily lead to a feeling of oppression and poor wearing comfort. Summary of the Invention

[0004] The main purpose of this application is to propose a wearable terminal product and a preparation method of a wearable part thereof, aiming to solve the technical problem of poor wearing comfort of users of existing wearable terminal products.

[0005] To achieve the above objectives, the present application proposes a wearable terminal product, characterized in that the wearable terminal product includes a main body, a contact portion that contacts the human body, and a connecting portion connecting the main body and the contact portion, wherein the contact portion and the connecting portion are integrally formed from a thermoplastic continuous fiber composite material to form a wearable portion; The reinforcing fibers in the thermoplastic continuous fiber composite material of the connecting portion are arranged in a first manner, wherein the first arrangement is used to enhance the rigidity of the connecting portion; The reinforcing fibers in the thermoplastic continuous fiber composite material of the contact portion are arranged in a second manner, wherein the second arrangement is used to make the contact portion flexible.

[0006] In one embodiment, the second arrangement includes reinforcing fibers arranged along a length direction perpendicular to the wearable portion having a density less than a predetermined low-density threshold.

[0007] In one embodiment, the first arrangement includes that the reinforcing fibers arranged along the length direction perpendicular to the wear portion are greater than a first high density threshold, and the reinforcing fibers arranged along the length direction parallel to the wear portion are greater than a second high density threshold.

[0008] In one embodiment, the first arrangement further includes reinforcing fibers arranged along a predetermined angle greater than a third high-density threshold, and the predetermined angle is between perpendicular to the length direction of the wearable portion and parallel to the length direction of the wearable portion.

[0009] In one embodiment, the contact portion is further covered with a soft plastic layer.

[0010] In one embodiment, the contact portion further includes a plurality of holes, and the holes are distributed in a predetermined array or a predetermined pattern.

[0011] The present invention also provides a method for preparing a wearable portion, the method comprising: A thermoplastic continuous fiber composite material sheet is hot-pressed into a wear portion blank using a hot pressing process, wherein the reinforcing fibers in the region of the thermoplastic continuous fiber composite material sheet corresponding to the wear portion blank are arranged in a first manner, the first arrangement being used to enhance the rigidity of the connecting portion, and the reinforcing fibers in the region of the thermoplastic continuous fiber composite material sheet corresponding to the wear portion blank are arranged in a second manner, the second arrangement being used to maintain the flexibility of the contact portion; The wearing portion embryonic body is subjected to surface treatment to obtain the wearing portion.

[0012] In one embodiment, before the step of performing surface treatment on the wearable portion embryo to obtain the wearable portion, the method includes: placing the wearable part embryo into an injection mold, and injecting liquid soft plastic into the contact area of ​​the wearable part embryo; After the liquid soft plastic is cooled, demoulding is performed to obtain a wearable part embryonic body in which the contact area is covered with the soft plastic.

[0013] In one embodiment, it is characterized in that, before the step of performing surface treatment on the wearable portion embryo to obtain the wearable portion, the method further comprises: Holes are drilled in the contact region of the wear portion embryonic body, wherein the holes drilled in the contact region of the wear portion embryonic body are distributed in a predetermined array or a predetermined pattern.

[0014] In one embodiment, the wearable portion is movably connected or fixedly connected to the main body portion.

[0015] The wearable portion described in the present application includes a connecting portion and a contact portion, wherein the connecting portion and the contact portion are integrally formed from a thermoplastic continuous fiber composite material. Therefore, the use of a thermoplastic continuous fiber composite material in the wearable portion of the present application can effectively reduce structural weight, and the structural strength can be ensured by the reinforcing fibers. The connecting portion and the contact portion of the wearable portion form a single integral structure, eliminating the weak connection points of the segmented structure. The reinforcing fibers in the thermoplastic continuous fiber composite material of the connecting portion of the wearable portion are arranged in a first manner, wherein the first arrangement is used to enhance the rigidity of the connecting portion. Since the connecting portion of the wearable portion is connected to the main body, by adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material to enhance the rigidity of the connecting portion, the bending and torsion resistance of the connection portion between the connecting portion and the main body can be improved. The reinforcing fibers in the thermoplastic continuous fiber composite material of the contact portion of the wearable portion are arranged in a second manner, wherein the second arrangement is used to provide flexibility to the contact portion. Since the contact portion of the wearable portion contacts the user's ear, by adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material to provide flexibility to the contact portion, the user's wearing comfort can be improved. Therefore, the present application effectively reduces the weight of the wearable portion by using a thermoplastic continuous fiber composite material. The reinforcing fibers in the thermoplastic continuous fiber composite material and the integrally molded overall structure ensure the strength of the overall structure. Furthermore, by adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material in the connecting and contact portions of the wearable portion, the rigidity of the connecting portion and the flexibility of the contact portion can be increased, thereby enhancing the wearer's wearing comfort while maintaining the rigidity of the wearable portion.

[0023] See also Figure 1 In one embodiment of the present application, the wearable terminal product includes a main body, a contact portion that contacts the human body, and a connecting portion connecting the main body and the contact portion, wherein the contact portion and the connecting portion are integrally formed into a wearable portion by a thermoplastic continuous fiber composite material; The reinforcing fibers in the thermoplastic continuous fiber composite material of the connecting portion are arranged in a first manner, wherein the first arrangement is used to enhance the rigidity of the connecting portion; The reinforcing fibers in the thermoplastic continuous fiber composite material of the contact portion are arranged in a second manner, wherein the second arrangement is used to make the contact portion flexible.

[0024] It should be noted that the thermoplastic continuous fiber composite material is a material obtained by compounding a resin matrix and reinforcing fibers, and the arrangement direction and distribution density of the reinforcing fibers in the resin matrix can be set according to the structural stress characteristics of the wearable part.

[0025] The reinforcing fibers may be continuous fiber materials such as carbon fiber, glass fiber, PBO (Poly-p-phenylene Benzobisoxazole) fiber, aramid fiber, plant fiber, etc., and the resin matrix may be thermoplastic resin materials such as PC (Poly-Carbonate), PA (Poly-Amide), PP (Poly-Propylene), PE (Poly-Ethylene), etc.

[0026] In addition, the wearable terminal product of the present invention can be a smart eyewear product such as XR glasses, audio glasses, video glasses, AI glasses, etc. For example, the wearable portion is the temple 100, the contact portion is the tail section 120 of the temple 100, the connecting portion is the front section 110 of the temple 100, and the main body is the frame body. The following description uses the structure of glasses as an example, but those skilled in the art should be aware that this technical solution is not limited to the application of smart eyewear products. It can be applied to any wearable terminal product that is used for wearable interaction with the human body and requires the integration of various functional devices, taking into account the rigidity of its functional area and the flexibility of the part that contacts the human body.

[0027] In this embodiment, the temple 100 includes a front section 110 and a rear section 120. The front section 110 and the rear section 120 of the temple 100 are integrally formed from a thermoplastic continuous fiber composite material. Since the temple 100 is made of a thermoplastic continuous fiber composite material, they can be directly integrally formed using a hot pressing process. Therefore, with the support of the reinforcing fibers, the temple 100 effectively reduces the weight of the structure while also ensuring sufficient structural strength. Furthermore, since the front section 110 and the rear section 120 are integrally formed from the thermoplastic continuous fiber composite material, there are no weak points in the segmented structure that could affect the overall structural strength of the temple 100.

[0028] The reinforcing fibers in the thermoplastic continuous fiber composite material of the front section 110 of the temple 100 are arranged in a first arrangement, wherein the first arrangement is used to enhance the rigidity of the front section 110 in the direction in which the force is applied. It is understood that within a range where the distribution density of the reinforcing fibers is below the density saturation point, the rigidity of the thermoplastic continuous fiber composite material increases as the distribution density of the reinforcing fibers increases. The rigidity of the thermoplastic continuous fiber composite material exhibits significant anisotropy, namely, the rigidity in the direction in which the reinforcing fibers are arranged is significantly higher than the rigidity in the direction perpendicular to the reinforcing fibers. Therefore, this embodiment can enhance the rigidity of the front section by increasing the distribution density of the reinforcing fibers and increasing the number of reinforcing fibers in the direction in which the force is applied, as the first arrangement. Since the front section 110 of the temple 100 is connected to the frame body, adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material to enhance the rigidity of the front section 110 can improve the bending and torsion resistance of the connection between the front section 110 and the frame body.

[0029] The reinforcing fibers in the thermoplastic continuous fiber composite material of the tail section 120 of the temple 100 are arranged in a second arrangement, wherein the second arrangement is designed to provide flexibility in the direction of force applied to the tail section 120. Similarly, the rigidity of the thermoplastic continuous fiber composite material decreases as the distribution density of the reinforcing fibers decreases; the rigidity of the thermoplastic continuous fiber composite material exhibits significant anisotropy, namely, the rigidity in the direction of the reinforcing fibers is significantly higher than the rigidity in the direction perpendicular to the reinforcing fibers. Therefore, this embodiment can adopt a second arrangement by reducing the distribution density of the reinforcing fibers and reducing the number of reinforcing fibers perpendicular to the length of the temple 100. This can at least reduce the rigidity of the tail section perpendicular to the length of the temple 100, thereby providing flexibility to the tail section 120. Since the tail section 120 of the temple 100 contacts the user's ear, adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material to provide flexibility in the tail section 120 can improve wearing comfort.

[0030] In a feasible embodiment, the second arrangement includes the reinforcement fibers arranged along the length direction perpendicular to the wearable portion having a density less than a predetermined low threshold value. That is, the second arrangement includes the reinforcement fibers arranged along the length direction perpendicular to the temple 100 having a density less than a predetermined low threshold value.

[0031] It should be noted that the predetermined low-density threshold is a pre-set distribution density value of the reinforcing fibers that meets the predetermined flexibility requirements in the force-bearing direction of the tail section 120. Because the distribution density values ​​that meet the predetermined flexibility requirements vary depending on the resin matrix material, reinforcing fibers, and the structural dimensions of the tail section 120, the predetermined low-density threshold can be selected in this embodiment based on the specific resin matrix, reinforcing fibers, and structural dimensions of the tail section 120.

[0032] Since the rigidity of thermoplastic continuous fiber composite materials along the direction of reinforcement fiber arrangement is significantly higher than that perpendicular to the direction of reinforcement fiber arrangement, and the tail section is primarily subjected to forces perpendicular to the length of the temple 100, this embodiment reduces the rigidity of the temple 100 along the direction perpendicular to the length of the temple 100 by reducing the distribution density of the reinforcement fibers arranged perpendicular to the length of the temple 100 to less than a predetermined low-density threshold, thereby reducing the rigidity of the temple 100 along the direction perpendicular to the length of the temple 100, thereby ensuring that the temple 100 has sufficient flexibility in the direction of force. Of course, it is understood that the second arrangement can also include a reinforcement fiber distribution density along the direction parallel to the length of the temple 100 greater than a predetermined high-density threshold. The predetermined high-density threshold is a predetermined reinforcement fiber distribution density value that meets the predetermined rigidity requirements of the tail section 120 in terms of the overall structure.

[0033] In a feasible embodiment, the first arrangement includes the reinforcing fibers arranged in a direction perpendicular to the length of the wearing portion having a density greater than a first high-density threshold, and the reinforcing fibers arranged in a direction parallel to the length of the wearing portion having a density greater than a second high-density threshold. That is, the first arrangement includes the reinforcing fibers arranged in a direction perpendicular to the length of the temple 100 having a density greater than the first high-density threshold, and the reinforcing fibers arranged in a direction parallel to the length of the temple 100 having a density greater than the second high-density threshold.

[0034] It should be noted that the first high-density threshold is a predetermined value for the distribution density of the reinforcing fibers of the front section 110 perpendicular to the length of the temple 100, which meets the predetermined rigidity requirement; and the second high-density threshold is a predetermined value for the distribution density of the reinforcing fibers of the front section 110 parallel to the length of the temple 100, which meets the predetermined rigidity requirement. Because the distribution density values ​​that meet the predetermined rigidity requirement vary depending on the resin matrix material, reinforcing fibers, and structural dimensions of the front section 110, in this embodiment, the first and second high-density thresholds can be selected based on the specific resin matrix, reinforcing fibers, and structural dimensions of the front section 110.

[0035] In this embodiment, the reinforcing fibers in the thermoplastic continuous fiber composite material of the front section 110 of the temple 100 are arranged in a first arrangement, wherein the reinforcing fibers arranged in a direction perpendicular to the length of the temple 100 have a density greater than a first high-density threshold, and the reinforcing fibers arranged in a direction parallel to the length of the temple 100 have a density greater than a second high-density threshold. This significantly improves the rigidity of the front section 110 of the temple 100 in the directions perpendicular and parallel to the length of the temple 100. Since the front section of the temple 100 is connected to the frame body of the smart glasses, adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material to enhance the rigidity of the front section 110 can improve the bending and torsion resistance of the connection between the front section 110 and the frame body.

[0036] In a feasible embodiment, the first arrangement further includes the reinforcement fibers arranged along a predetermined angle greater than a third high-density threshold, and the predetermined angle is between a direction perpendicular to the length of the wearing portion and a direction parallel to the length of the wearing portion. That is, the first arrangement further includes the reinforcement fibers arranged along a predetermined angle greater than a third high-density threshold, and the predetermined angle is between a direction perpendicular to the length of the temple 100 and a direction parallel to the length of the temple 100.

[0037] It should be noted that the third high-density threshold is a predetermined distribution density value of the reinforcing fibers of the front section 110 in a predetermined angle direction that meets a predetermined rigidity requirement. The third high-density threshold is a predetermined distribution density value of the reinforcing fibers of the front section 110 in a predetermined angle direction that meets a predetermined rigidity requirement. The predetermined angle is between perpendicular to the length direction of the temple 100 and parallel to the length direction of the temple 100.

[0038] In this embodiment, the reinforcing fibers in the thermoplastic continuous fiber composite material of the front section 110 of the temple 100 are arranged along a predetermined angle, which is located between a direction perpendicular to the length of the temple 100 and a direction parallel to the length of the temple 100. This significantly improves the rigidity of the front section 110 of the temple 100 in the directions perpendicular to and parallel to the length of the temple 100, further enhancing the rigidity of the front section 110 and the bending and torsion resistance of the connection between the front section 110 and the frame body.

[0039] In a feasible embodiment, the contact portion is further coated with a soft plastic layer, that is, the tail section 120 of the temple 100 is further coated with a soft plastic layer.

[0040] It should be noted that the soft plastic layer is a soft polymer material such as PC, PA, TPU (Thermoplastic Polyurethane), silicone, etc.

[0041] In this embodiment, the tail section 120 of the temple 100 may be coated with a soft plastic layer. It is understood that the entire tail section 120 may be coated with the soft plastic layer, or the area of ​​the tail section 120 that contacts the user's ear may be coated with the soft plastic layer. Therefore, this embodiment can further improve the local elasticity of the tail section 120, further enhancing the user's wearing comfort, and making the temple 100 more versatile and decorative.

[0042] In a feasible embodiment, the contact portion further includes a plurality of holes, which are distributed in a predetermined array or a predetermined pattern. That is, the tail section 120 of the temple 100 further includes a plurality of holes, which are distributed in a predetermined array or a predetermined pattern.

[0043] The thermoplastic continuous fiber composite material of the tail section 120 of the temple 100 is partially perforated (the hole location, shape, and spacing can be flexibly designed). The tail section 120 of the temple 100 also includes a plurality of holes distributed in a predetermined array or pattern. The holes can be through holes or blind holes, and the hole parameters such as hole location, shape, and spacing can be selected according to specific needs. This embodiment can further reduce weight, achieving extreme lightweight, while also reducing the local rigidity of the tail section 120 of the temple 100 without affecting the overall strength of the temple 100.

[0044] Furthermore, the several holes on the tail section 120 are also conducive to the subsequent embedding of soft polymer materials and coordinated deformation, so that the soft polymer materials are filled in the holes. Firstly, a buffer and flexible transition are formed to disperse stress and increase the structural elasticity of the tail section 120; secondly, mechanical bite is formed to increase the connection strength and stability of the two heterogeneous materials, the thermoplastic continuous fiber composite material and the soft polymer material, thereby improving the structural reliability of the temple 100.

[0045] In another feasible embodiment, the wearing portion in the embodiment of the present application is movably connected or fixedly connected to the main body. That is, the wearing portion is movably connected or fixedly connected to the frame main body. The movable connection method can be a hinge connection, a snap-on connection, a magnetic connection, a bolt and nut connection, etc. The fixed connection method of the wearing portion and the main body can be that the wearing portion and the main body are integrally formed or welded or glued together.

[0046] In the technical solution of the embodiment of the present application, the wearable portion includes: a connecting portion and a contact portion, and the connecting portion and the contact portion of the wearable portion are integrally formed from a thermoplastic continuous fiber composite material. Therefore, the use of a thermoplastic continuous fiber composite material in the wearable portion of the embodiment of the present application can effectively reduce the structural weight, and the reinforcing fibers can ensure structural strength. The connecting portion and the contact portion of the wearable portion form a single structure, eliminating the connection weaknesses of the segmented structure. The reinforcing fibers in the thermoplastic continuous fiber composite material of the connecting portion of the wearable portion are arranged in a first arrangement, wherein the first arrangement is used to enhance the rigidity of the connecting portion. Since the connecting portion of the wearable portion is connected to the main body, by adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material to enhance the rigidity of the connecting portion, the bending and torsion resistance of the connection portion between the connecting portion and the main body can be improved. The reinforcing fibers in the thermoplastic continuous fiber composite material of the contact portion of the wearable portion are arranged in a second arrangement, wherein the second arrangement is used to provide flexibility to the contact portion. Since the contact portion of the wearable portion contacts the user's ear, by adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material to provide flexibility to the contact portion, the user's wearing comfort can be improved. Therefore, the embodiment of the present application, by using a thermoplastic continuous fiber composite material, can effectively reduce the weight of the wearable portion. The reinforcing fibers in the thermoplastic continuous fiber composite material and the integrally molded overall structure ensure the strength of the overall structure. In addition, by adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material in the connecting and contact portions of the wearable portion, the rigidity of the connecting portion and the flexibility of the contact portion can be increased, thereby improving the wearer's wearing comfort while maintaining the rigidity of the wearable portion.

[0047] Based on this, the embodiment of the present application provides a method for preparing a wearable portion of a wearable terminal product, that is, a method for preparing a wearable portion, referring to Figure 2 , Figure 2 Schematic diagram of a process for preparing a wearable portion according to an embodiment of the present invention.

[0048] In this embodiment, the method for preparing the wearable portion is used to prepare the wearable portion as described above, comprising steps S10 to S20: Step S10, hot pressing the thermoplastic continuous fiber composite material sheet into a wear portion blank using a hot pressing process, wherein the reinforcing fibers in the connection region of the thermoplastic continuous fiber composite material sheet corresponding to the wear portion blank are arranged in a first manner, the first arrangement being used to enhance the rigidity of the connection portion, and the reinforcing fibers in the contact region of the thermoplastic continuous fiber composite material sheet corresponding to the wear portion blank are arranged in a second manner, the second arrangement being used to maintain the flexibility of the contact portion; It should be noted that the hot pressing process is a process operation that uses heat and pressure to shape plastic materials in a mold. The thermoplastic continuous fiber composite material sheet is a sheet-shaped thermoplastic continuous fiber composite material, and the thickness of the thermoplastic continuous fiber composite material sheet is at least not less than the thickness of the temple.

[0049] In this embodiment, a thermoplastic continuous fiber composite sheet can be hot-pressed into a temple blank using a hot pressing process, wherein the reinforcing fibers in the front region of the thermoplastic continuous fiber composite sheet corresponding to the temple blank are arranged in a first manner, the first arrangement being used to enhance the rigidity of the front region of the temple blank, and the reinforcing fibers in the tail region of the thermoplastic continuous fiber composite sheet corresponding to the temple blank are arranged in a second manner, the second arrangement being used to maintain the flexibility of the tail region of the temple blank. Thus, the temple blank formed by hot pressing the thermoplastic continuous fiber composite sheet has a strong rigidity in the front region and a flexibility in the tail region. Exemplarily, in this embodiment, the thermoplastic continuous fiber composite sheet is a continuous carbon fiber reinforced PC-based composite material with a wall thickness of 0.2-0.7 mm. In this embodiment, the thermoplastic continuous fiber composite sheet can be heated to a material forming temperature (200-300°C), a forming pressure of 2-20 MPa, and cooled to form the temple blank. In this embodiment, the thermoplastic continuous fiber composite sheet is a continuous carbon fiber reinforced PA-based composite material with a wall thickness of 0.2-0.7 mm. In this embodiment, the thermoplastic continuous fiber composite sheet can be heated to the material forming temperature (140-300°C) and a forming pressure of 2-20 MPa. After cooling and shaping, the temple blank is obtained. Furthermore, this embodiment can also heat the mold in the hot pressing process by extremely rapid cooling and heating, which can further improve the molding appearance quality, shorten the production cycle, and increase production efficiency.

[0050] Step S20: performing surface treatment on the wearable part embryo to obtain the wearable part.

[0051] After obtaining the wearable portion blank, this embodiment can also perform surface treatments such as cutting off the edge material of the shell and performing surface decoration to obtain a wearable portion that meets the product appearance and performance requirements.

[0052] In a feasible implementation manner, steps A10 to A20 may be included before step S20: Step A10: placing the wearable part embryo into an injection mold, and injecting liquid soft plastic into the contact area of ​​the wearable part embryo; In step A20, after the liquid soft plastic is cooled, demolding is performed to obtain a wearable part embryonic body in which the contact area is coated with the soft plastic.

[0053] It should be noted that the soft plastic is a soft thermoplastic polymer material such as PC, PA, TPU (Thermoplastic Polyurethane), silicone, etc. The injection mold is a mold for the soft plastic layer covering the contact area of ​​the wearable part embryo.

[0054] In this embodiment, the wearable part embryo is placed in an injection mold, and liquid soft plastic is injected into the contact area of ​​the wearable part embryo. After the liquid soft plastic is cooled, the wearable part embryo is demolded to obtain the wearable part embryo with the contact area coated with soft plastic. Exemplarily, in this embodiment, a secondary injection of silicone coating can be performed at the contact area of ​​the wearable part embryo. In this embodiment, the contact area of ​​the wearable part embryo with the cut edge can be placed in an injection mold, liquid silicone rubber can be injected, the temperature and pressure can be controlled, the material can be vulcanized, and the wearable part embryo can be demolded after cooling to obtain the wearable part embryo with the contact area coated with silicone.

[0055] In this embodiment, the wearable part blank is placed in an injection mold, and liquid soft plastic is injected into the contact area of ​​the wearable part blank. After the liquid soft plastic cools, it is demolded to obtain the wearable part blank with the contact area coated with soft plastic. Therefore, this embodiment can further improve the local elasticity of the contact area of ​​the wearable part blank, further enhancing the user's wearing comfort, and making the wearable part's appearance more diverse and convenient for decoration and coloring.

[0056] In another feasible implementation manner, step B10 may be further included before step S20: Step B10: drilling holes in the contact region of the wearable portion embryonic body, wherein the holes drilled in the contact region of the wearable portion embryonic body are distributed in a predetermined array or a predetermined pattern.

[0057] It should be noted that the predetermined array is an array of preset holes, and the predetermined pattern is a distribution pattern of preset holes.

[0058] In this embodiment, localized holes are opened in the contact region of the wearable portion embryonic body (with flexible design of hole location, shape, and spacing). The tail section 120 of the temple 100 also includes a plurality of holes distributed in a predetermined array or pattern. Hole parameters such as hole location, shape, and spacing can be selected based on specific needs. This embodiment further reduces weight, achieving extreme lightweight while also reducing the local rigidity of the tail section 120 of the temple 100, without compromising the overall strength of the temple 100. Furthermore, this embodiment can also incorporate the technical solutions of steps A10-A20. The holes in the contact region of the wearable portion facilitate the subsequent insertion of the soft polymer material, allowing for coordinated deformation and filling the holes. This creates a buffer and flexible transition, dissipating stress and increasing the structural elasticity of the contact region. Furthermore, it creates a mechanical bond, increasing the strength and stability of the connection between the thermoplastic continuous fiber composite material and the soft polymer material, thereby enhancing the structural reliability of the wearable portion. This embodiment uses a hot pressing process to hot-press a thermoplastic continuous fiber composite sheet into a wearable body. The wearable body is then perforated in the contact area of ​​the body and the outer shell edge material is removed. The holes are arranged in a predetermined array or pattern, with a diameter of 0.3-3 mm and a spacing of 0.3-2 mm. The wearable body is then placed in an injection mold, and liquid soft plastic is injected into the contact area of ​​the wearable body. After the liquid soft plastic cools, it is demolded to obtain a wearable body with a tail section coated with soft plastic. The wearable body can further undergo surface decoration to meet product appearance and performance requirements.

[0059] The embodiment of the present application provides a method for preparing a wearable part, wherein a thermoplastic continuous fiber composite material sheet is hot-pressed into a wearable part blank by a hot pressing process, wherein the reinforcing fibers in the connection area of ​​the thermoplastic continuous fiber composite material sheet corresponding to the wearable part blank are arranged in a first manner, the first arrangement being used to enhance the rigidity of the connection area of ​​the wearable part blank, and the reinforcing fibers in the contact area of ​​the thermoplastic continuous fiber composite material sheet corresponding to the wearable part blank are arranged in a second manner, the second arrangement being used to maintain the flexibility of the contact area of ​​the wearable part blank; the wearable part blank is surface-treated to obtain the wearable part. Therefore, the embodiment of the present application can effectively reduce the weight of the wearable part by using a thermoplastic continuous fiber composite material, and the reinforcing fibers in the thermoplastic continuous fiber composite material and the overall structure integrally formed by the hot pressing process ensure the strength of the overall structure. In addition, by adjusting the arrangement of the reinforcing fibers in the thermoplastic continuous fiber composite material in the connection area and the contact area of ​​the wearable part, the rigidity of the front section and the flexibility of the rear section can be improved, thereby ensuring the rigidity of the wearable part of the wearable terminal product while improving the wearing comfort of the user.
