Description

Technical Field

[0001] This application relates to the technical field of wearable products, and more particularly to a support plate for a flip watch and a flip watch. Background Technology

[0002] Currently, watches with a flip function on the market mainly consist of three parts: a support plate, a strap, and a watch head. The strap, as a connector, is attached to both ends of the support plate, forming a loop structure that can be worn on the user's wrist. The watch head is mounted on the support plate in a flip-up manner, allowing the user to easily flip the watch head to the most suitable angle according to actual needs.

[0003] However, most existing support plates use a structure of plastic and stainless steel molded together. Although this material combination ensures the strength and stability of the support plate to a certain extent, the relatively high density of stainless steel makes the entire support plate heavy. This increases the overall weight of the watch and affects the user's wearing comfort. After wearing it for a long time, the user may feel wrist fatigue or discomfort. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a support plate for a flip watch and a flip watch, which can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On the one hand, a support plate for a reversible watch is provided, comprising:

[0007] The inner substrate includes a metal plate and a fiberglass plate, wherein the metal plate is provided with a rotating mounting part for connecting to the rotating mounting seat of the meter head;

[0008] An outer adhesive layer is applied to the outside of the inner substrate.

[0009] Optionally, the support plate includes opposing hinge ends and fastening ends, and the metal plate is disposed relative to the fiberglass plate near the hinge ends;

[0010] The metal plate also includes an extension connected to the rotating mounting portion, the extension extending relative to the rotating mounting portion toward the side where the fastening end is located.

[0011] Optionally, the extension portion extends 7.5 to 10 mm relative to the rotating mounting portion toward the side where the fastening end is located.

[0012] Optionally, the extension includes a U-shaped connecting root and two extension arms. The connecting root is connected to the rotating mounting part, and the two extension arms are respectively connected to both ends of the connecting root and extend towards the side where the fastening end is located, so that a U-shaped groove is formed between the two extension arms.

[0013] Optionally, the corners of the sidewalls of the U-shaped groove are rounded.

[0014] Optionally, the thickness of the extension arm is not less than 0.9 mm; and / or, the width of the extension arm is not less than 4.5 mm.

[0015] Optionally, the fiberglass board includes an inner frame and an outer edge plate. One side of the inner frame extends into the U-shaped groove, and the other side extends toward the side where the fastening end is located. The outer edge plate is U-shaped and surrounds the portion of the inner frame located outside the U-shaped groove.

[0016] Optionally, the outer edge plate is provided with adhesive-pulling holes, and the adhesive material of the outer coating layer is filled into the adhesive-pulling holes.

[0017] Optionally, the outer adhesive layer covers the outer edge plate, leaving the surface of the inner frame exposed.

[0018] Optionally, a glue-pulling groove is provided on the side wall of the inner frame facing the extension, and the glue material of the outer coating layer is filled into the glue-pulling groove.

[0019] On the other hand, a flip-up watch is provided, including a watch head and the aforementioned support plate, wherein the watch head is flip-up and mounted on the support plate.

[0020] The beneficial effects of this application are as follows: This utility model provides a support plate for a flip-up watch and a flip-up watch. In the support plate structure, the inner base plate adopts a combination structure of metal plate and fiberglass plate, which significantly reduces the weight of the support plate compared to the traditional stainless steel die-cast structure. The metal plate is only used in key stress areas (such as the rotating mounting part), while the fiberglass plate is used in other less stressed areas. This material distribution method ensures strength while effectively reducing the overall weight. The weight-reduced support plate reduces the overall weight of the watch, thereby improving the user's wearing comfort and reducing the possibility of wrist fatigue or discomfort after prolonged wear.

[0030] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] The support plate of existing reversible watches is mostly made of plastic and stainless steel through die-casting. Although this material combination ensures the strength and stability of the support plate to a certain extent, the relatively high density of stainless steel makes the entire support plate heavy. This increases the overall weight of the watch and affects the user's wearing comfort. After wearing it for a long time, the user may feel wrist fatigue or discomfort.

[0034] To overcome the above technical problems, this embodiment provides a support plate for a flip-up watch, which reduces the weight of the support plate while maintaining sufficient structural strength, and also takes into account the advantage of low material cost.

[0035] like Figures 1-6 As shown, the support plate in this embodiment specifically includes:

[0036] The inner substrate 1 includes a metal plate 11 and a fiberglass plate 12. The metal plate 11 is provided with a rotating mounting part 111, which is used to connect with the rotating mounting seat of the meter head.

[0037] An outer adhesive layer 2 is applied to the outside of the inner substrate 1.

[0038] The inner substrate 1 serves as the foundation for providing the main strength support inside the support plate. It consists of two parts: a metal plate 11 and a fiberglass plate 12. Relatively speaking, the metal plate 11 has higher strength but is heavier; while the fiberglass plate 12 has slightly lower strength, but its strength is still much greater than that of the outer adhesive layer 2, and it has the advantage of being lightweight.

[0039] In the structure of the reversible watch, the watch head is mounted on the rotating mounting part 111 of the support plate via a rotating mounting base. During use, the area of ​​the rotating mounting part 111 is the main stress area. Making the rotating mounting part 111 of metal ensures sufficient structural strength and fatigue resistance, thereby guaranteeing the reliability of the support plate. Furthermore, using fiberglass board 12 as a local support inside the support plate, and considering that the stress on the area supported by the fiberglass board 12 is relatively small, it can meet sufficient performance requirements. Compared to using a completely metal structure, the combination of metal plate 11 and fiberglass board 12 obviously results in a lighter weight.

[0040] In addition, fiberglass board 12 has a lower material cost compared to other lightweight and high-strength materials (such as carbon fiber boards).

[0041] The metal plate 11 is preferably made of high-strength steel, aluminum alloy, or titanium alloy.

[0042] Based on the sufficient support strength provided by the inner substrate 1, an outer adhesive layer 2 is provided to cover the outer surface of the inner substrate 1. The outer adhesive layer 2 not only provides a good appearance and feel, but also has the advantages of low cost and light weight. In addition, the outer adhesive layer 2 can reliably combine the metal plate 11 and the fiberglass plate 12 to form a complete support plate. At the same time, the choice of adhesive material can further optimize the wearing comfort of the watch.

[0043] In summary, the support plate provided in this embodiment has at least the following beneficial effects:

[0044] 1) Weight Reduction and Improved Wearing Comfort: By using a combination of metal plate 11 and fiberglass plate 12 as the inner base plate 1, the weight of the support plate is significantly reduced compared to the traditional stainless steel die-cast structure. Metal plate 11 is used only in critical stress areas (such as the rotating mounting part 111), while fiberglass plate 12 is used in other less stressful areas. This material distribution method ensures strength while effectively reducing overall weight. The weight-reduced support plate lowers the overall weight of the watch, thereby improving user wearing comfort and reducing the likelihood of wrist fatigue or discomfort after prolonged wear.

[0045] 2) Lower cost: Compared with other lightweight and high-strength materials such as carbon fiber boards, fiberglass board 12 has a lower material cost. This allows the support plate to maintain high performance while keeping production costs low, thus improving the product's market competitiveness.

[0046] 3) Good integrity and stability: The outer adhesive layer 2 reliably combines the metal plate 11 and the fiberglass plate 12 to form a complete support plate, which improves the stability and consistency of the structure. This combined structure enables the support plate to maintain high strength and light weight while also having good integrity and durability.

[0047] In one embodiment, combined with Figures 1-3 The support plate includes a hinge end 3 and a fastening end 4, and the metal plate 11 is disposed near the hinge end 3 relative to the fiberglass plate 12.

[0048] The metal plate 11 also includes an extension 112 connected to the rotating mounting portion 111, the extension 112 extending relative to the rotating mounting portion 111 toward the side where the fastening end 4 is located.

[0049] Specifically, in a reversible watch, one end of the watch head is connected to a rotating mounting base, and the other end is equipped with a latch. During assembly, the rotating mounting base is connected to the rotating mounting portion 111 of the support plate (i.e., the location of the hinge end 3). When the latch is engaged with the fastening end 4 of the support plate, the watch head is fixed flatly on the support plate. When the latch is unlocked, the watch head can be flipped upright relative to the support plate based on the rotating mounting base. That is, the hinge end 3 is the end where the rotating mounting portion 111 is located, and this end area experiences greater force during use.

[0050] In this embodiment, the metal plate 11 is positioned closer to the hinge end 3 than the fiberglass plate 12. This is because the hinge end 3 is the main area connecting the meter head and the support plate, and it is also the part that experiences significant stress during use. The high strength of the metal plate 11 ensures that this critical area has sufficient structural strength and fatigue resistance, thereby guaranteeing the reliability and durability of the support plate. Furthermore, the metal plate 11 includes an extension 112 connected to the rotating mounting portion 111. This extension 112 extends towards the fastening end 4, increasing the area and strength of the metal plate 11. Simultaneously, the extension 112 provides stable support for the rotating mounting portion 111, helping to distribute and bear the torque and stress generated during the meter head's rotation, preventing deformation or damage to the support plate, and improving the overall structural stability of the support plate during rotation.

[0051] Using fiberglass board 12 in non-critical load-bearing areas (i.e., the area outside the hinge end 3) reduces the overall weight of the support plate and lowers material costs. Although fiberglass board 12 is slightly less strong than metal, it is sufficient for these low-stress areas.

[0052] In one embodiment, such as Figure 4As shown, the length L1 of the extension portion 112 extending relative to the rotating mounting portion 111 toward the side where the fastening end 4 is located is 7.5 to 10 mm.

[0053] The presence of the extension 112 helps to distribute the torque and stress generated during the rotation of the dial indicator more evenly onto the support plate. The length of 7.5–10 mm ensures that the extension 112 effectively bears a portion of the force, reducing the individual stress on the rotating mounting part 111, thereby improving the fatigue resistance and service life of the entire support plate. The length of the extension 112 is set within the range of 7.5–10 mm, ensuring sufficient extension length to enhance the connection stability between the metal plate 11 and the rotating mounting part 111 and the overall rigidity of the support plate, while avoiding material waste and weight increase due to excessive length. This length range represents an optimized balance between structural strength and material cost.

[0054] Further preferred, L1 = 8.5–9 mm.

[0055] In one embodiment, the extension 112 includes a U-shaped connecting root 1121 and two extension arms 1122. The connecting root 1121 is connected to the rotating mounting part 111, and the two extension arms 1122 are respectively connected to the two ends of the connecting root 1121 and extend toward the side where the fastening end 4 is located, so that a U-shaped groove is formed between the two extension arms 1122.

[0056] The U-shaped connection root 1121 is connected to the rotating mounting part 111, forming a stable support point. Specifically, the connection root 1121 ensures a sufficiently large connection area with the rotating mounting part 111, guaranteeing the reliability of the entire metal plate 11. Two extension arms 1122 extend from both ends of the connection root 1121. This structure requires less material, is lighter, and can effectively distribute and bear the force from the meter head, enhancing the structural stability of the support plate during the flipping process.

[0057] Reference Figure 1 In the support plate provided in this embodiment, a hollow hole 5 is also provided in the central area. The hollow hole 5 can effectively reduce the weight of the support plate and reduce material consumption. In addition, the hollow hole 5 can also be used to accommodate the back structure after the meter head is recycled, so that the overall structure of the meter head and support plate combination is thinner.

[0058] In the support plate structure, with the hinge end 3 located in front of the perforated hole 5 and the fastening end 4 located behind the perforated hole 5, in the metal plate 11 structure, the extension arm 1122 extends from front to back relative to the rotating mounting part 111. Since the two extension arms 1122 are respectively connected to the left and right ends of the connecting root 1121, and a U-shaped groove is formed between the two extension arms 1122, it can be understood that the two extension arms 1122 can extend to the left and right sides of the perforated hole 5, and the U-shaped groove can avoid the perforated hole 5. Obviously, in this structure, the extension arms 1122 extending to the left and right sides of the perforated hole 5 can provide reliable reinforcement to the local positions on the left and right sides of the perforated hole 5 near the rotating mounting part 111, reducing the risk of bending and breaking in the area with high stress.

[0059] In one embodiment, the corners of the sidewalls of the U-shaped groove are rounded.

[0060] The rounded transition at corners effectively disperses and alleviates stress, preventing stress concentration at sharp corners and reducing the risk of cracking or breakage in that area. This is crucial for improving the overall strength and durability of the support plate. The rounded transition not only conforms to mechanical principles but also gives the support plate a smoother, more harmonious line, enhancing the product's aesthetics and visual appeal. Furthermore, the rounded transition design is relatively easy to implement during manufacturing, reducing processing difficulty and costs, and improving production efficiency and product quality.

[0061] In one embodiment, such as Figure 4 As shown, the thickness L3 of the extension arm 1122 is not less than 0.9 mm; and / or, the width L2 of the extension arm 1122 is not less than 4.5 mm.

[0062] As an important structural component supporting the pallet, the thickness and width of the extension arm 1122 directly affect its load-bearing capacity and bending resistance.

[0063] The thickness L3 of the extension arm 1122 is not less than 0.9mm. A thicker extension arm 1122 can better resist wear and deformation during long-term use and extend the service life of the support plate.

[0064] The width L2 of the extension arm 1122 is not less than 4.5mm. The wider extension arm 1122 enhances strength and provides a larger contact area, dispersing stress, reducing the risk of local stress concentration, and further improving durability.

[0065] In one embodiment, reference is made to Figure 3The fiberglass board 12 includes an inner frame 121 and an outer edge plate 122. One side of the inner frame 121 extends into the U-shaped groove, and the other side extends toward the side where the fastening end 4 is located. The outer edge plate 122 is U-shaped and surrounds the portion of the inner frame 121 located outside the U-shaped groove.

[0066] As the core component of the fiberglass board 12, the inner frame 121 extends into the U-shaped groove on one side. This allows for the creation of a complete perforated hole 5 structure within the internal space of the inner frame 121, resulting in a more stable support plate structure and improved overall appearance. Furthermore, the extension of one side of the inner frame 121 into the U-shaped groove provides a larger contact area with the metal plate 11. Combined with the outer adhesive layer 2, this enhances the stability of the entire support plate structure. In practice, a certain distance is maintained between the outer wall of the inner frame 121 and the inner wall of the extension 112, allowing the adhesive material to fill the outer adhesive layer 2 during injection molding. This achieves better coverage of the metal plate 11 and the fiberglass board 12, improving the stability and reliability of the entire structure.

[0067] The outer edge plate 122 is U-shaped and surrounds the portion of the inner frame 121 located outside the U-shaped groove. This not only enhances the overall structural strength of the fiberglass board 12 but also allows the fiberglass board 12 to better bond with the outer adhesive layer 2, improving the reliability of the entire support plate. In addition, the outer edge plate 122 can also be provided with some irregular structures to accommodate the fastening structure of the fastening end 4.

[0068] In one embodiment, reference is made to Figure 4 The outer edge plate 122 is provided with a glue-pulling hole 1221, and the glue material of the outer coating layer 2 is filled into the glue-pulling hole 1221.

[0069] The presence of the adhesive-pulling hole 1221 allows the adhesive material of the outer adhesive layer 2 to fill it, forming a mechanical locking effect. Specifically, after the adhesive material fills the adhesive-pulling hole 1221, a tighter connection structure is formed, effectively preventing the outer adhesive layer 2 from falling off or cracking due to external forces during use. This tight connection structure improves the overall durability of the fiberglass board 12 and the outer adhesive layer 2, making the product more durable and reliable.

[0070] In one embodiment, the outer adhesive layer 2 covers the outer edge plate 122, leaving the surface of the inner frame 121 exposed.

[0071] The surface of the inner frame 121 is exposed. Specifically, the thickness of the inner frame 121 can be set to be the same as the overall thickness of the outer adhesive layer 2. Compared to the outer edge plate 122, the thickness of the inner frame 121 is effectively increased. Obviously, this greatly improves the strength of the fiberglass board 12 and enhances the reliability of the entire support plate. Therefore, this structure can improve the reliability of the entire support plate while ensuring a reliable bond between the outer adhesive layer 2 and the fiberglass board 12.

[0072] In one embodiment, a glue-pulling groove 1211 is provided on the side wall of the inner frame 121 facing the extension 112, and the glue material of the outer adhesive layer 2 is filled into the glue-pulling groove 1211.

[0073] Specifically, an outer edge plate 122 is not provided in the area of ​​the inner frame 121 facing the extension 112, thus lacking space for providing a glue-pulling hole 1221 in this area. In this embodiment, a glue-pulling groove 1211 facing the extension 112 is provided in this area. The presence of the groove allows the adhesive material of the outer adhesive layer 2 to deeply fill it, forming a tight mechanical lock with the side wall of the inner frame 121, thereby enhancing the bonding strength between the two and effectively preventing the outer adhesive layer 2 from falling off due to external forces during use, thus improving the durability and reliability of the product.

[0074] On the other hand, a flip-up watch is provided, including a watch head and the aforementioned support plate, wherein the watch head is flip-up and mounted on the support plate.

[0075] Specifically, the flip-up watch in this embodiment also includes a watch strap, with both ends of the strap connected to the two ends of a support plate to form a loop structure that can be worn on the wrist. The watch head is mounted on the support plate via a rotating mounting base, allowing the user to adjust the angle of the watch head as needed, effectively optimizing the user experience and providing richer functionality.

[0076] Based on the support plate of this embodiment, similarly, the flip watch of this solution has the advantages of high reliability and light weight.
