[0002] With the improvement of intelligence level, smart wearable watches have become a necessity in people's lives. At present, conventional smart wearable watches use virtual pointers to replace the previous traditional mechanical pointer design, while some consumers still pursue mechanical pointer solutions. The combination of conventional smart watches and traditional mechanical pointer watches is a new trend of development, which not only retains the high-end atmosphere of pointer design, but also realizes intelligent touch display.
[0003] Traditional smart wearable watches are stacked up from bottom to top with a perforated screen, a touch layer, an air layer and a casing. The air layer is used to place the mechanical pointer. If the pointer requires a larger air layer, it will be difficult for a touch IC to support the above touch operations, which will cause the touch IC to work abnormally, or a more powerful touch IC will need to be configured.

[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0028] The utility model provides an easy-to-control smart wearable watch, which includes a casing, a touch layer, an air layer, and a drilled screen. The touch layer is fixed to the lower surface of the casing by optical adhesive, and a touch IC is arranged on the touch layer; the air layer is arranged below the touch layer, and the air layer is used to place a mechanical pointer; the drilled screen is arranged below the air layer, and the drilled screen includes a lower polarizer, a lower substrate, an upper substrate and an upper polarizer which are sequentially stacked from bottom to top, the lower substrate is longer than the upper substrate and extends outward to form a step, and an FPC is bound to the upper surface of the lower substrate located at the step.
[0029] Since the touch layer is set under the casing and the air layer is placed under the touch layer, the thickness of the air layer below has little effect on the touch effect. The choice of touch IC basically depends on the material and thickness of the cover. Therefore, this structure can easily realize touch operation using ordinary touch IC, and can ensure the normal operation of the touch IC without configuring a more powerful touch IC.
[0030] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0031] Example 1
[0032] See also Figure 1, an easy-to-control smart wearable watch provided by the utility model includes a casing 1, a touch layer 2, an air layer 3, and a drilled screen 4. The touch layer 2 is fixed to the lower surface of the casing 1 by optical glue 5, and a touch IC is arranged on the touch layer 2; the air layer 3 is arranged below the touch layer 2, and the air layer 3 is used to place a mechanical pointer; the drilled screen 4 is arranged below the air layer 3, and the drilled screen 4 includes a lower polarizer 41, a lower substrate 42, an upper substrate 43 and an upper polarizer 44 which are sequentially stacked from bottom to top, the lower substrate 42 is longer than the upper substrate 43 and extends outward to form a step, and the upper surface of the lower substrate 42 located at the step is bound with FPC6. Since the touch layer 2 is arranged below the casing 1, and the air layer 3 is placed below the touch layer 2, the thickness of the air layer 3 below has little effect on the touch effect. The selection of the touch IC basically depends on the material and thickness of the cover. Therefore, this structure can easily realize touch operation using an ordinary touch IC, and can ensure the normal operation of the touch IC without configuring a more powerful touch IC.
[0033] Example 2
[0034] See also Figure 2 As a further optimization scheme of Example 1, in this embodiment, the FPC6 includes a substrate layer 61, a circuit layer 62 arranged on the upper surface of the substrate layer 61, and a metal heat dissipation layer 63 arranged on the lower surface of the substrate layer 61. The arrangement method can be that the circuit layer 62 and the metal heat dissipation layer 63 are respectively attached to the substrate layer 61 by double-sided adhesive. Since the thickness of the substrate layer 61 is relatively thin, the heat on the FPC6 can be diffused to the metal heat dissipation layer 63 through the substrate layer 61. The metal heat dissipation layer 63 can effectively increase the heat dissipation area of the FPC6 and play a role in uniform heat dissipation, thereby improving the heat dissipation efficiency of the FPC6. The substrate layer 61 can be any one of polyimide, polyester, polysulfone or polytetrafluoroethylene, the double-sided adhesive is any one of an acrylic adhesive layer or an epoxy resin adhesive layer, and the metal heat dissipation layer 63 can be a copper foil layer.
[0035] Furthermore, the FPC 6 also includes at least one through-hole 64 penetrating the substrate layer 61, the circuit layer 62 and the metal heat dissipation layer 63, and the inner wall of the through-hole 64 is provided with a heat-conducting layer in contact with the circuit layer 62 and the metal heat dissipation layer 63. By utilizing the good thermal conductivity of the through-hole 64, the circuit layer 62 and the metal heat dissipation layer 63 on both sides of the substrate layer 61 can be electrically connected to play a good thermal conductivity function, and the thermal conductive layer can provide a thermal conductive function to achieve a good heat dissipation effect. Among them, the thermal conductive layer can be a copper glue conductive ink layer.
[0036] Furthermore, a heat conductor connected to an external heat-conducting structure is disposed in the through hole 64. The heat conductor is connected to the external heat-conducting structure from one side of the circuit layer 62 and is also in contact with the heat-conducting layer in the through hole 64, so that the circuit layer 62 and the metal heat dissipation layer 63 can be connected to the external heat-conducting structure through the through hole 64, so that the heat in the FPC 6 can be diffused to the external heat-conducting structure through the heat conductor in the through hole 64, so as to further improve the heat dissipation efficiency of the FPC 6. Preferably, in order to enable the through hole 64 to be connected to the external heat-conducting structure, the through hole 64 is disposed at the edge of the FPC 6.
[0037] Furthermore, the metal heat dissipation layer 63 is a uniform heat dissipation structure, and its structure can be any one of a mesh structure, a strip structure, a wavy structure or a honeycomb structure. Through the uniform heat dissipation structure, the heat dissipation effect can be better improved.
[0038] Example 3
[0039] See also Figure 3 As a further optimization scheme of Example 1, in this embodiment, two reinforcing plates 7 are provided on both sides of FPC6 and are staggered with each other. In the traditional FPC6 design, reinforcing plates 7 are usually not provided or are provided at the same position and have the same width, resulting in the pressure applied being concentrated on the same straight line when plugging and unplugging FPC6, causing a slight break in the FPC6 line. The FPC6 provided by the utility model has two reinforcing plates 7 located on both sides of the connecting portion and staggered with each other. When the FPC6 is pulled out, the pressure exerted by the reinforcing plates 7 on the two sides on the FPC6 is not on the same line segment, and the stress will not be concentrated on the same straight line when bending, thereby avoiding stress concentration and the problem of easy slight break in the line at the interface end, thereby improving the product yield.
[0040] Furthermore, the two mutually staggered reinforcing plates 7 referred to in the utility model can be respectively arranged at two different positions; or the center point position can be the same, but the widths of the two reinforcing plates 7 are different. It is sufficient to make the stress of the two reinforcing plates 7 not be concentrated on the same straight line when they are bent, which can avoid stress concentration and the problem of easy micro-breakage of the line at the interface end, thereby improving the product yield. In this embodiment, the reinforcing plates 7 include a first reinforcing plate and a second reinforcing plate, and the widths of each reinforcing plate 7 are different, and their center points are on the same horizontal line, so that the edges of the reinforcing plates 7 are staggered and not concentrated on the same straight line.
[0041] Furthermore, the material of the reinforcing plate 7 is FR4, PI or stainless steel. In other embodiments, if the heat generated by the FPC 6 is relatively large, a heat dissipation material with a better heat dissipation effect, such as an aluminum foil reinforcing plate 7, may also be used.
[0042] Furthermore, the outer surfaces of the first reinforcement plate and the second reinforcement plate are both provided with a surface treatment layer for increasing the surface roughness, so as to increase the friction between the worker and the first reinforcement plate and the second reinforcement plate, so that the FPC6 is easy to pull out.
[0043] Furthermore, the surface treatment layer is provided with diamond knurling on the outer surfaces of the first reinforcement plate and the second reinforcement plate, so that the FPC6 can be pulled out more easily, reducing the risk of the FPC6 circuit being broken.
[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application.
