[0029] Please refer to Figures 1 to 4 The double-color middle frame provided by the embodiments of the present application comprises a decorative part body 100, a middle frame 200 and a connecting assembly 300; the decorative part body 100 is provided with an insertion hole 110; injection of glue material through the insertion hole 110 forms the connecting assembly 300 to realize the fixed connection of the decorative part body 100 on the end face of the middle frame 200; the decorative part body 100 and the middle frame 200 are integrally formed.

[0030] In the embodiment, unlike the prior art watch middle frame 200 which is fixedly connected by components of different materials and different colors through point gluing or buckle assembly, the middle frame 200 in the embodiment is integrally formed by fusing the decorative part body 100 and the middle frame 200 through glue injection, and the decorative part body 100 and the middle frame 200 adopt a two-color design, which meets the waterproof effect of the watch middle frame 200 while realizing the design of the two-color effect. In addition, the two-color effect can be realized without using surface treatment processes such as silk printing, laser engraving, spraying and electroplating, so as to avoid the problem of low user experience caused by the falling of the appearance color.

[0031] Specifically, first, appropriate plastic materials for the decorative part body 100 are selected, such as ABS (Acrylonitrile Butadiene Styrene), PC (Polycarbonate), etc. According to the design requirements, the molten plastic is injected into the mold using an injection molding machine to obtain the decorative part body 100 by one-time injection molding, wherein at least one insertion hole 110 is provided on the decorative part body 100. Second, after the first injection molding, a plastic material different in color from the middle frame 200 is selected for the second injection molding to obtain the middle frame 200. Finally, the molten glue is injected into the insertion hole 110 of the decorative part body 100, and the molten glue forms a connecting assembly 300 through the insertion hole 110 to realize the fixed connection of the decorative part body 100 on the middle frame 200. After waiting for the glue to cool and solidify, the two-color middle frame 200 is trimmed and polished to realize the fixed connection of the decorative part body 100 and the middle frame 200 and ensure the integral molding of the decorative part body 100 and the middle frame 200.

[0032] On the one hand, the decorative part body 100 and the middle frame 200 adopt a two-color design, which increases the visual level and aesthetic degree of the watch middle frame 200. Different color combinations can be selected according to different market demands and user preferences to make the product more attractive and personalized. On the other hand, compared with the traditional connection method, the connection method of fixing the decorative part body 100 on the middle frame 200 by filling the connecting assembly 300 with molten glue in the embodiment not only enables the watch to have good waterproof effect, but also reduces the production cost of the watch.

[0033] In an embodiment, as shown in Figure 1 and Figure 2 The decorative part body 100 is provided with a decorative ring 120 and a plurality of assembly holes 130; the decorative ring 120 is annularly arranged on the outer surface edge of the decorative part body 100; and the plurality of assembly holes 130 are respectively arranged on a plurality of protrusions on the inner surface of the decorative part body 100.

[0034] In the embodiment, the decorative body 100 is circular, and the decorative ring 120 and the decorative body 100 are integrally formed by injection molding in a mold, so that the tight combination between the decorative body 100 and the decorative ring 120 is ensured, and the entire decorative part is more durable. In addition, the injection molding process can complete the forming of the decorative body 100 and the decorative ring 120 at one time, without the need for multiple processing and assembly, thereby greatly shortening the production cycle and improving the production efficiency. The inner surface of the decorative body 100 is annularly provided with a plurality of protrusions, and a hole is formed in each protrusion to form an assembly hole 130 for fixing the main plate on the decorative body 100. Specifically, the assembly hole 130 is matched with a screw, and the main plate is fixed on the decorative body 100 by a plurality of screws.

[0035] In an embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the decorative ring 120 comprises a first connecting portion 121 and a second connecting portion 122; a first end face of a middle portion of the first connecting portion 121 is away from a plane where an end portion of the decorative body 100 by a first preset distance, and a first end face of a middle portion of the second connecting portion 122 is away from the plane where the end portion of the decorative body 100 by a second preset distance; the first preset distance is smaller than the second preset distance.

[0036] In the embodiment, the decorative ring 120 is composed of the first connecting portion 121 and the second connecting portion 122 connected to each other, and the first connecting portion 121 and the second connecting portion 122 are alternately arranged. The decorative ring 120 in the embodiment comprises two first connecting portions 121 and two second connecting portions 122 alternately connected to each other, wherein the first connecting portion 121 is annularly arranged on the outer surface of the circular decorative body 100 in a concave shape, and the second connecting portion 122 is annularly arranged on the outer surface of the decorative body 100 in a circular arc shape.

[0037] The first end faces of the first connecting portion 121 and the second connecting portion 122 are the same, and are the end faces facing the middle frame 200. The plane where the end portion of the decorative body 100 is located is the plane where the end portion of the decorative body 100 facing the middle frame 200 is located. Since the first connecting portion 121 is in a concave shape and the second connecting portion 122 is in a circular arc shape, the distance between the first end face of the middle portion of the first connecting portion 121 and the plane where the end portion of the decorative body 100 is located is smaller than the distance between the first end face of the middle portion of the second connecting portion 122 and the plane where the end portion is located.

[0038] The first connecting portion 121 in a concave shape and the second connecting portion 122 in a circular arc shape are alternately arranged annularly on the outer surface of the decorative body 100, and after the decorative body 100 and the middle frame 200 are assembled together, the shape design of the appearance of the middle frame 200 is avoided to be single.

[0039] In an embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the middle frame 200 comprises a middle frame body 210, a key hole 220 and a plurality of lugs 230; the key hole 220 is arranged on the middle frame body 210; the middle frame body 210 is outwardly convex on both sides to form the plurality of lugs 230; the key hole 220 is located between any two adjacent lugs 230.

[0040] In particular, the plurality of lugs 230 comprises a first lug 231, a second lug 232, a third lug 233 and a fourth lug 234; the first lug 231 and the second lug 232 are symmetrically arranged and adjacent to each other, and the third lug 233 and the fourth lug 234 are symmetrically arranged and adjacent to each other; the first lug 231 and the third lug 233 are symmetric about the central axis of the middle frame body 210, and the second lug 232 and the fourth lug 234 are symmetric about the central axis of the middle frame body 210.

[0041] In the embodiment, the middle frame body 210 is in the shape of a circular ring, and its diameter is the same as that of the first end surface of the decorative member body 100. The key hole 220 is arranged on the side circumference of the middle frame body 210 and adjacent to the first connecting part 121, i.e., between the first lug 231 and the third lug 233 or between the second lug 232 and the fourth lug 234. The first lug 231, the second lug 232, the third lug 233 and the fourth lug 234 are each provided with a watchband hole for mounting a watchband (not shown in the figure). The two second connecting parts 122 of the decorative ring 120 are symmetrically arranged on the outer surface of the decorative member body 100 at the positions where the two lugs are connected to the decorative member body 100, and the two first connecting parts 121 are respectively located between the two second connecting parts 122.

[0042] In particular, the watchband hole comprises a first watchband hole, a second watchband hole, a third watchband hole and a fourth watchband hole; the first watchband hole is arranged on the first lug 231 and located on the side of the first lug 231 facing the second lug 232, and the second watchband hole is arranged on the second lug 232 and located on the side of the second lug 232 facing the first lug 231; the first watchband hole and the second watchband hole are matched with each other to mount a first watchband; the third watchband hole is arranged on the third lug 233 and located on the side of the third lug 233 facing the fourth lug 234, and the fourth watchband hole is arranged on the fourth lug 234 and located on the side of the fourth lug 234 facing the third lug 233; the third watchband hole and the fourth watchband hole are matched with each other to mount a second watchband.

[0043] In the embodiment, the middle frame body 210 is symmetrically provided with a plurality of table ears 230 on both sides, and the table ears 230 are symmetrically arranged with each other. The symmetric structure can uniformly disperse the force when the middle frame 200 is subjected to force. For example, when the smart watch is installed with a watchband through the table ears 230, and subjected to external force such as tension and torsion in daily wearing process, the symmetric structure of the table ears 230 can ensure that the force is uniformly distributed on the middle frame body 210, reduces the local stress concentration, thereby enhancing the stability of the structure of the middle frame 200, and reducing the risk of deformation or damage of the middle frame 200 due to uneven force.

[0044] In addition, the middle frame 200 is manufactured by means of secondary injection molding, which significantly improves the production efficiency. Compared with multiple injection molding or other complex molding processes, the secondary injection molding can complete the manufacturing of the middle frame 200 and the injection molding of the decorative part body 100 in a shorter time, reducing the production process and time cost. At the same time, after the decorative part body 100 is injection molded once, the middle frame 200 is injection molded on the outer surface of the decorative part body 100, which ensures the structural integrity and quality stability of the whole middle frame 200 and the decorative part body 100. In order to avoid the size deviation and poor combination that may occur in the process of splicing different parts or multiple molding, not only the size precision of the middle frame 200 is higher and the structural strength is more uniform, which is conducive to the control and improvement of the quality of the watch, but also the waterproof effect of the middle frame 200 of the watch is significantly improved.

[0045] In an embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the first end surface of the decorative part body 100 is the end surface facing the middle frame body 210, and the second end surface of the decorative part body 100 is the end surface away from the middle frame body 210; the connecting assembly 300 includes a connecting plate 310 and a connecting piece 320, the injection glue passes through the insertion hole 110 to form the connecting plate 310 on the first end surface of the decorative part body 100, and forms the connecting piece 320 on the second end surface of the decorative part body 100, and the connecting plate 310 and the connecting piece 320 are communicated through the insertion hole 110.

[0046] In the embodiment, according to the actual installation needs of the middle frame body 210 and the decorative part body 100, the part extending to the second end surface of the decorative part body 100 from the inner surface of the middle frame body 210 on both sides is formed as the connecting piece 320 in the injection mold. Compared with the mode that the connecting piece 320 is fixedly connected to the middle frame body 210 through a screw, the connecting piece 320 formed by the mold injection in the embodiment can have a more firm connection effect and will not have a gap between the connecting piece 320 and the middle frame body 210 to affect the waterproof effect of the middle frame 200.

[0047] The inner surface of the connecting plate 310 faces the center of the middle frame body 210, while the outer surface of the connecting plate 310 faces away from the inner surface. The two sides of the middle frame body 210 between the first and second watch straps are concave curved surfaces, which are adapted to the U-shaped first connecting portion 121. The bottom of the connecting plate 310 is also concave curved, and this concave curved surface is also adapted to the U-shaped first connecting portion 121. The connecting plate 310 is fixed to the middle frame body 210 by the connector 320. The space formed between the bottom concave curved surface of the connecting plate 310 and the end face of the concave curved surface on the middle frame body 210 is adapted to the U-shaped first connecting portion 121 of the same size.

[0048] Specifically, based on the decorative part body 100 formed by injection molding, the decorative part body 100 is placed in the middle frame mold and molten adhesive is poured in. After molten injection processing, a connecting plate 310 and the middle frame body 210 are formed. The connecting plate 310 is formed from the inside out by the molten adhesive passing through the insertion hole 110 towards the concave curved surface on the middle frame body 210. After the connecting plate 310 is formed, the excess molten adhesive forms a connector 320, which then blocks the insertion hole 110 and connects to the middle frame body 210. The injection molded adhesive fills the gap between the connecting plate 310 and the decorative part body 100 through the insertion hole 110 of the decorative part body 100. Then, through molten injection, the decorative part body 100, the first connecting part 121, and the middle frame body 210 are integrally formed, so that the watch middle frame 200 achieves excellent waterproof performance. Meanwhile, since the decorative body 100 and the middle frame 200 adopt a two-color design, the overall molded watch middle frame 200 can achieve a two-color effect to meet the watch's appearance design requirements.

[0049] In addition, the outer surface of the connecting plate 310 can be used to engrave logos or trademarks to enrich the watch's appearance design.

[0050] In one embodiment, such as Figure 1 As shown, the connecting plate 310 includes a first connecting plate 311 and a second connecting plate 312; the first connecting plate 311 and the second connecting plate 312 are symmetrical about the central axis of the middle frame body 210.

[0051] In specific implementation, the connector 320 includes a first connector 321 and a second connector 322; one end of the first connector 321 is fixedly connected to the inner surface of the middle part of the first connecting plate 311, and the other end is fixedly connected to the inner surface of the middle frame body 210; one end of the second connector 322 is fixedly connected to the inner surface of the middle part of the second connecting plate 312, and the other end is fixedly connected to the inner surface of the middle frame body 210.

[0052] In the embodiment, the first connecting plate 311 and the second connecting plate 312 are fixed on both sides of the middle frame body 210 between the first watchband and the second watchband, and are symmetrical about the central axis of the middle frame body 210. The first connecting piece 321 and the second connecting piece 322 connect the first connecting plate 311 and the second connecting plate 312 to the inner surface of the middle frame body 210, and the connection forms a stable triangular structure. The triangular structure has stability in mechanics, which can effectively enhance the connection strength between the connecting plate 310 and the middle frame body 210. Through the reinforcing effect of the connecting piece 320, the connecting plate 310 is not easy to separate from the middle frame body 210 even when bearing a large external force, further improving the reliability of the middle frame 200 structure.

[0053] In addition, from the appearance, the symmetrical connecting plate 310 design presents a neat and harmonious beauty, which meets the aesthetic concept of the public, so that the watch looks more delicate and professional. Even if the watch realizes the multi-color effect, the coordination of the appearance is an important factor that cannot be ignored. The symmetrical structure can improve the overall image of the watch and enhance the attractiveness of the watch in the market.

[0054] In an embodiment, as shown in Figure 4 The first antenna 400 and the second antenna 500 are arranged between the decoration body 100 and the middle frame body 210, and are fixedly connected to the outer surfaces of the opposite sides of the decoration body 100.

[0055] In the embodiment, the first antenna 400 is a GPS (Global Positioning System) antenna, and the second antenna 500 is a BLE (Bluetooth Low Energy) antenna. Specifically, the first antenna 400 and the second antenna 500 are arranged between the decoration body 100 and the middle frame body 210. After the first injection molding of the decoration body 100, the outer surface of the decoration body 100 is processed by laser engraving and chemical plating to make the laser engraving area conductive, forming the first antenna 400 (GPS antenna) and the second antenna 500 (BLE antenna), and attaching to the outer surface of the decoration body 100, so that the first antenna 400 and the second antenna 500 are away from the mainboard, to reduce the interference of the internal electronic components of the watch on the first antenna 400 and the second antenna 500.

[0056] By utilizing laser engraving and electroplating processes to achieve a conductive state in the laser-engraved area to form an antenna, the shape and performance of the first antenna 400 and the second antenna 500 can be precisely controlled. Laser engraving enables high-precision pattern creation, while electroplating helps to form a good conductive layer, thereby ensuring that both the first antenna 400 and the second antenna 500 can effectively receive and transmit signals. Compared with other antenna manufacturing processes, the manufacturing process in this embodiment can better adapt to the limited space and complex structure inside a watch, thus producing an antenna that meets performance requirements.

[0057] During the second injection molding, the decorative part body 100, to which the first antenna 400 and the second antenna 500 are attached, is placed into the injection mold. The middle frame 200 is then formed through secondary injection molding, covering the outer surface of the decorative part body 100 to form a unified whole. This prevents the first antenna 400 (GPS antenna) and the second antenna 500 (BLE antenna) from being exposed and affecting the watch's appearance, and also prevents damage to the first antenna 400 (GPS antenna) and the second antenna 500 (BLE antenna) from external forces. This extends the antenna's lifespan, reduces watch malfunctions caused by antenna damage, and improves the watch's reliability and durability.

[0058] In the long run, on the one hand, it reduces the cost of frequent replacements due to damage to the first antenna (400nm) or the second antenna (500nm); on the other hand, the double-injection molding process is relatively mature, and production costs can be reduced during mass production by optimizing mold design and raw material procurement. Furthermore, the integrated nature of the process reduces additional parts and complex assembly steps, which also helps lower the overall production cost of the watch.

[0059] This utility model embodiment also provides a meter header, such as Figure 5 As shown, the watch includes a two-tone frame as in any of the preceding embodiments, as well as a screen assembly 600 and a bottom case assembly 700; the screen assembly 600 is fixedly connected to the first end face of the decorative body 100; the bottom case assembly 700 is fixedly connected to the first end face of the frame body 210, and the first end face of the frame body 210 is the end face facing away from the decorative body 100.

[0060] In the embodiment, the decoration body 100 is integrally formed with the middle frame body 210 by one-time injection molding of the decoration body 100 and secondary injection molding of the outer surface of the decoration body 100, and the molten adhesive is injected into the insertion hole 110 of the decoration body 100 to integrally form the decoration body 100 and the middle frame body 210, wherein the decoration body 100 and the middle frame body 210 adopt a double-color design.
