Description

Technical Field

[0001] This utility model mainly relates to the field of watch technology, specifically to an anti-static plastic back cover type electronic watch. Background Technology

[0002] Students and office workers often wear watches to keep track of time, with electronic watches being particularly popular due to their ability to integrate more functions. However, the human body is a unique carrier of static electricity and a typical source of static electricity hazard. Walking or friction with other objects causes the accumulation of charge on the body, known as static electricity. When wearing an electronic watch, this static electricity can enter the watch's internal components, potentially affecting their normal operation or even causing damage, thus reducing the watch's durability.

[0003] Existing technology includes a wristband, an electronic watch face, and a connection between the wristband and the electronic watch face. The electronic watch face comprises an insulating mounting base, a conductive plate at the bottom of the mounting base, and a discharge hole on the vertical side wall of the mounting base. A discharge needle and a conductive resistor are located within the discharge hole, and the discharge needle is conductively connected to the conductive plate through the conductive resistor. By modifying the mechanism of the smartwatch and integrating its functions, it facilitates the release of static electricity from the human body, thus protecting the electronic components of the smartwatch to some extent and extending its lifespan. However, the discharge needle design requires it to penetrate the watch case and be located close to the watch face, which may affect the overall water resistance and structural strength of the watch. Utility Model Content

[0004] The purpose of this invention is to provide an anti-static plastic-backed electronic watch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-static plastic-backed electronic watch, comprising an electronic dial and a plastic back cover, wherein the plastic back cover is fixed to the bottom of the electronic dial, a conductive metal mesh is provided inside the plastic back cover, and multiple conductive silicone blocks connected to the conductive metal mesh are embedded in the bottom of the plastic back cover. An annular groove is also formed in the bottom of the plastic back cover, and an annular copper foil and a conductive rubber ring are sequentially arranged on the annular groove. The annular copper foil is connected to the conductive metal mesh. Lugs are also fixed on both sides of the bottom of the plastic back cover, and the lugs are connected to the conductive rubber rings. A conductive watch strap is provided on the lugs, and an electrostatic discharger is provided on the conductive watch strap.

[0006] Preferably, a connecting rod is rotatably disposed between the two ear positions of the hook, the connecting rod penetrates the conductive watch strap and is connected and fixed thereto, and a first conductive magnetic absorbing piece is fixedly disposed at both ends of the connecting rod, a second conductive magnetic absorbing piece that fits with the first conductive magnetic absorbing piece is embedded and fixed in the hook, and a conductive rod is also embedded and fixed in the hook, the two ends of the conductive rod being connected to the second conductive magnetic absorbing piece and the conductive rubber ring respectively.

[0007] Furthermore, the hanging ear is made of plastic, and the connecting rod is made of 316L stainless steel.

[0008] Preferably, the conductive strap is made of antibacterial conductive fiber material.

[0009] Preferably, a connector is provided between the conductive straps on both sides, and the electrostatic discharger is located on the side of the connector away from the electronic dial.

[0010] Compared with existing technologies, the advantages of this invention are as follows: An anti-static plastic-backed electronic watch uses a conductive silicone block to contact the skin, guiding static electricity from the skin to a conductive metal mesh embedded in the plastic back cover. This static electricity is then guided through an annular copper foil and a conductive rubber ring to a magnetic component inside the lug, and finally discharged by the strap release mechanism. The first and second magnetic plates work together for static adsorption and conduction, while dynamically separating due to centrifugal force during strap rotation to prevent wear. This achieves efficient charge transfer without requiring openings in the watch body. The combination of the plastic casing and the flexible conductive medium simultaneously satisfies waterproofing, impact resistance, and biocompatibility.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 6 As shown, an anti-static plastic-backed electronic watch includes an electronic dial 1 and a plastic back cover 2. The plastic back cover 2 is fixed to the bottom of the electronic dial 1. A conductive metal mesh 9 is provided inside the plastic back cover 2. Multiple conductive silicone blocks 8 connected to the conductive metal mesh 9 are embedded in the bottom of the plastic back cover 2. An annular groove is also opened at the bottom of the plastic back cover 2. An annular copper foil 10 and a conductive rubber ring 11 are arranged sequentially on the annular groove. The annular copper foil 10 is connected to the conductive metal mesh 9. Lugs 3 are fixed on both sides of the bottom of the plastic back cover 2. The lugs 3 are connected to the conductive rubber ring 11. A conductive watch strap 4 is provided on the lugs 3. An electrostatic discharger 6 is provided on the conductive watch strap 4.

[0025] A connecting rod 7 is rotatably disposed between the two ear positions of the hook 3. The connecting rod 7 penetrates the conductive watch strap 4 and is fixedly connected to it. A first electromagnetic absorbing piece 13 is fixedly disposed at both ends of the connecting rod 7. A second electromagnetic absorbing piece 14 that fits with the first electromagnetic absorbing piece 13 is embedded and fixed in the hook 3. A conductive rod 12 is also embedded and fixed in the hook 3. The two ends of the conductive rod 12 are respectively connected to the second electromagnetic absorbing piece 14 and the conductive rubber ring 11.

[0026] The first magnetic magnetic absorbing piece 13 and the second magnetic magnetic absorbing piece 14 are both magnetic absorbing pieces with a gold plating layer on the surface to enhance conductivity. The thickness of the gold plating layer is 3 micrometers, which is not easily worn and will affect the use. In addition, when the first magnetic magnetic absorbing piece 13 rotates dynamically with the connecting rod 7, it will elastically deform in the direction of the connecting rod 7 under the action of centrifugal force, resulting in dynamic separation, which further avoids wear of the gold plating layer and makes the use more stable.

[0027] The ear loop 3 is made of plastic, and the connecting rod 7 is made of 316L stainless steel. The main body of the ear loop 3 is insulated with plastic to prevent the strong magnetic field around the electronic dial 1 from interfering with its use.

[0028] The conductive strap 4 is made of antibacterial conductive fiber material. The static electricity on the connecting rod 7 is conducted to the static discharger 6 and released outward through the conductive strap 4.

[0029] A connector 5 is provided between the conductive watch straps 4 on both sides. The connector 5 can be a buckle to connect and fix the conductive watch straps 4 at both ends. The static discharger 6 is located on the side of the connector 5 away from the electronic watch face 1. When worn, the static discharger 6 is away from the wrist and faces outward air to ionize or release static electricity by contacting external objects such as clothing.

[0030] The implementation principle of this application embodiment is as follows: During the use of this product, the static electricity generated at the human wrist will be directly conducted along the conductive silicone block 8, conductive rubber ring 11 and conductive watch strap 4 that are in contact with the wrist. The static electricity on the conductive silicone block 8 is first conducted to the conductive metal mesh 9, and then conducted along the mesh to the annular copper foil 10, and then further conducted to the conductive rubber ring 11. The static electricity on the conductive rubber ring 11 is guided by the conductive rod 12 to the second conductive magnetic absorbing piece 14. When the watch is worn, the position of the connecting rod 7 is fixed, so the first conductive magnetic absorbing piece 13 and the second conductive magnetic absorbing piece 14 are statically magnetically fixed. The static electricity is directly conducted from the connecting rod 7 to the conductive watch strap 4, and finally guided to the static electricity release device 6 of the electronic watch face 1, where it is ionized in the air or released when it comes into contact with external objects such as clothing. The overall structure is stable and does not affect the waterproof performance of the electronic watch face 1.

[0031] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
