Description

Technical Field

[0001] The utility model relates to the technical field of mechanical watches, in particular to a pointer-type solar watch. Background Art

[0002] A solar pointer watch is a watch that uses light energy to power its watch. It can convert light energy into electrical energy through a built-in solar cell (photovoltaic cell). When the solar cell on the watch dial is exposed to sunlight or other light sources, it converts the light energy into electrical energy and stores it in the battery to power the movement.

[0003] In the prior art, solar cells are generally located on the dial, but when the solar cells are located on the dial, the dial needs to leave a certain amount of space for sunlight to directly enter the dial, but the structure on the dial is compact, and the illumination range provided for the solar cells is small, the charging of the solar cells is limited, and at the same time, the solar cells are not easy to assemble and disassemble when installed on the dial.

[0014] Compared with the prior art, the utility model provides a pointer-type solar watch with the following features:

[0015] Beneficial effects:

[0016] 1. The utility model sets a ring-shaped solar cell. When the user wears the watch, sunlight can penetrate into the metal case through the glass mirror. The solar cell located between the dial and the metal case can convert light energy into electrical energy to power the movement. Moreover, since the user usually wears the watch with the metal case tilted, the sunlight can better irradiate the solar cell. The pointer-type solar watch can effectively increase the range of sunlight irradiation of the solar cell. Moreover, the solar cell is ring-shaped and can be fixed without being embedded in the dial, which is convenient for subsequent disassembly.

[0017] 2. The utility model provides a transparent plastic dial ring so that the transparent plastic dial ring can be embedded in the inner diameter of the solar cell.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: a pointer-type solar watch, comprising: a metal case 1, a movement 2 and a metal back cover 3, the movement 2 is installed in the metal case 1, the metal back cover 3 covers the metal case 1, a glass mirror 4 is installed on the metal case 1, a dial 5 and a pointer 6 are installed on the side of the movement 2 facing the glass mirror 4, a ring-shaped solar cell 7 is installed between the dial 5 and the metal case 1, and the solar cell 7 supplies energy to the movement 2. It should be noted that the solar cell 7 is electrically connected to the movement 2, and its installation method can be that the solar cell 7 is clamped and fixed by the dial 5 and the metal case 1, or it can be fixed by bonding or bolting. How the movement 2 drives the pointer 6 to move is a prior art, that is, it will not be described in detail, and the movement 2 is not described in detail in the figure, but only illustrated.

[0027] The pointer 6 type solar watch with the above structure is provided with an annular solar cell 7. When the user wears the watch, sunlight can be projected into the space between the metal case 1 through the glass mirror 4, and the solar cell 7 located between the dial 5 and the metal case 1 can convert light energy into electrical energy to power the movement 2. Moreover, since the user usually wears the watch with the metal case 1 tilted, the sunlight can better illuminate the solar cell 7. The pointer 6 type solar watch can effectively increase the range of sunlight exposure of the solar cell 7. The solar cell 7 is annular and can be fixed without being embedded in the dial 5, which is convenient for subsequent assembly and disassembly. This solves the problem that the watch in the prior art provides a small exposure range for the solar cell 7, which limits the charging of the solar cell 7, and the solar cell 7 is not convenient for assembly and disassembly when installed on the dial 5.

[0028] In this embodiment, in order to facilitate the disassembly and replacement of the solar cell 7 and minimize the impact on the solar cell 7, a transparent plastic dial ring 8 is provided between the dial 5 and the metal case 1, and the transparent plastic dial ring 8 can be embedded in the inner diameter of the solar cell 7. Afterwards, when the metal case 1 and the movement 2 are covered and abutted against each other, the metal case 1 and the movement 2 clamp and fix the transparent plastic dial ring 8, and the solar cell 7 located between the transparent plastic dial ring 8 and the metal case 1 is restricted by the transparent plastic dial ring 8 and the metal case 1.

[0029] In this embodiment, in order to prevent the metal watch case 1 from being directly exposed to sunlight, and the solar cell 7 being ring-shaped, the metal watch case 1 will block the sunlight, so that the solar cell 7 cannot be directly exposed to the sunlight and can only be exposed to reflected light, thereby limiting the charging of the solar cell 7. In order to allow the solar cell 7 to be exposed to direct sunlight, the glass watch mirror 4 has a relative flat surface 41 and an inner concave surface 42, and the inner concave surface 42 faces the dial 5. When sunlight is directly exposed to the glass watch mirror 4, the sunlight is affected by the inner concave surface 42 and diverges, so that part of the sunlight can be directed to the solar cell 7.

[0030] In this embodiment, in order to ensure that the thickness of the watch is thin so that the wearer can wear it comfortably and like it, the thickness of the movement 2 is set to 5.98 mm, and the overall thickness of the watch, that is, the thickness between the metal back cover 3 and the glass mirror 4, is set to 8.9 mm.

[0031] In this embodiment, in order to ensure the comfort of the wearer when wearing the watch, lugs 10 are provided on the metal case 1, and fabric straps 9 are installed on the lugs 10. Compared with leather straps, fabric straps 9 have better air permeability and comfort.

[0032] In this embodiment, in order to facilitate the wearer to quickly lock the clock scale and minute scale, a rectangular first scale protrusion 11 and a pointer 6-shaped second scale protrusion 12 are provided on the dial 5. The first scale protrusion 11 and the second scale protrusion 12 are both fixedly distributed in a circular array on the side of the dial 5 facing the glass mirror 4. The first scale protrusion 11 is the scale for every minute, and the second scale protrusion 12 is the scale for every hour.

[0033] Working principle: When the user wears the watch, sunlight can penetrate into the metal case 1 through the glass mirror 4, and the solar cell 7 located between the dial 5 and the metal case 1 can convert light energy into electrical energy to power the movement 2. Moreover, since the user usually wears the watch at an angle, the sunlight can better illuminate the solar cell 7. When the watch is exposed to direct sunlight, since the glass mirror 4 has a relative flat surface 41 and an inner concave surface 42, the sunlight is affected by the inner concave surface 42 and diverges, so that part of the sunlight can be directed toward the solar cell 7.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
