WO2005116781A1 - A radio watch - Google Patents

Abstract

The utility model relates to a radio watch which includes a movement, a transparent cover, a bottom cover and a casing body formed by fixing an upper casing body to a lower casing body. The upper casing body whose top end extends a loop towards the transparent cover is made of metallic material, and has a pair of casing lugs disposed outwards along the direction of the diameter thereof which are for mounting watch bands. The lower casing body in which the movement is placed is made of plastic material. The casing body is circular, quadrate or elliptoid and so on. The surface of the bottom end of the upper casing body has a groove disposed along its circumference, accordingly the surface of the top end of the lower casing body has a protuberance disposed to be embedded into the groove. Alternatively the body of the upper casing body covers the surface of the lower casing body. The upper casing body and the lower casing body are glued to be fastened or tightly held by a fixture. The advantage of the utility model is to use the metal-plastic combining casing body, so seen from the front it has no difference with the all-metallic watch casing and overcomes the defect of the shielding space formed by the all-metallic casing at the same time.

Description

 Radio Watch Technology

 The utility model relates to the structure of a wristwatch, in particular to a radio wave watch. Background technique

 As a new generation of timing tools, the radio wave watch mainly uses the built-in antenna to receive the radio signal containing the time code to adjust the time to achieve high accuracy. The accuracy of this radio-controlled watch depends on whether the radio signal can penetrate the case without obstacles, thereby ensuring the sensitivity of the built-in watch movement to receive radio signals.

 The all-metal case can be effectively connected with the metal strap. In addition, the unique gloss of the metal and the variety of processing methods will greatly increase the texture of the entire watch and have a good appearance. However, the all-metal case will A shielding space is formed around the watch movement, which affects the receiving effect of the antenna inside the watch movement, which in turn affects the running accuracy of the entire watch.

 In order to solve the problem of radio wave signal penetrability, radio-controlled watches use non-metallic cases, mainly plastic cases, but neither the aesthetics of the appearance nor the overall texture can match the metallic materials, especially stainless steel. In the same way, even if the surface of the plastic case is sprayed with a color as close as possible to the appearance of the metal band, the texture of the metal case cannot be achieved.

At present, there are still some comprehensive designs, which are mainly covered with a metal ring on the upper end of the plastic case close to the periphery of the glass, so as to maximize the surface similarity to the metal case, but the metal part of this design It only occupies a very small part of the entire shell, and the structure can not be changed in its nature as a non-metallic material. It can only be regarded as a change in appearance. Utility model content

 As an improvement of the present invention, a groove is provided along the periphery of the lower end surface of the upper casing, and a protrusion that can be embedded in the groove is correspondingly provided on the top surface of the lower casing; A groove is provided along the periphery of the top surface of the body, and a protrusion that can be embedded in the groove is correspondingly provided on the lower end surface of the upper casing. A waterproof ring is placed in the groove. In this way, the plastic part has a protruding part embedded in the four grooves of the metal part, and a waterproof ring made of plastic material is appropriately placed between the two parts to achieve the waterproof function.

 In order to ensure the tightness of the combination of metal and plastic, the lower shell of the plastic part is provided with more than two first screw holes along the periphery, and the upper shell is correspondingly provided with more than two screw holes, and the shell is screwed. The corresponding hole position of the metal part is connected with the first screw hole of the plastic part, thereby achieving the purpose of fastening.

As another improvement of the present utility model, the upper case body is covered on the surface of the lower case body, and the upper case body and the lower case body are adhesively fixed or fastened with a screw pin. This waterproof function is made of plastic The lower half made of plastic material is completed independently, and the upper half and lower half made of metal material are combined by means of bonding or clamping.

 The lower casing is provided with more than two second screw holes along the periphery, and the bottom cover is correspondingly provided with more than two screw holes for fastening the bottom cover and the lower casing.

 The outer surface of the lower shell (16) is covered with a ring-shaped metal sheet.

 The metal material may be copper, alloy, stainless steel, or titanium; the bottom cover is made of plastic material, and the waterproof function of the joint part with the shell body is completed according to the common practice in the industry; the plastic material is engineering plastic.

 The utility model adopts a metal and plastic casing, in addition to the glass and the bottom cover, the watch case is divided into two organic components, the upper half (mainly the ring mouth, the ears and a part of the body). It is made of metal material (usually copper, alloy, stainless steel, titanium, etc.), and the lower part is made of plastic material (usually ABS or PC). In this way, when viewed from the front, it is no different from an all-metal case. From the bottom and side, it can be divided into different parts of metal and non-metal. From the aspect of waterproof structure, two schemes are provided for selection.

 The utility model has the advantage that the structure of the radio wave watch adopts a metal and plastic case, which is no different from an all-metal case when viewed from the front, and is beautiful and elegant; and also solves the problem that the all-metal case will form a periphery around the watch core. Defects in shielding space.

 The technical content of the present invention will be further described in detail below through the drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
