It should be noted that this embodiment corresponds to the relevant quantity and appearance mentioned in the accompanying drawings, which are only used for specific description. The embodiments of the present invention are used to facilitate understanding of the content of the present invention, rather than to limit the protection scope of the present invention.

As shown in FIG. 1 and FIG. 2A , this embodiment provides an electronic device 100 with a waterproof structure (eg, a watch, glasses, or earphones, etc.), but the type of the electronic device 100 with a waterproof structure is not limited thereto. That is to say, a non-wearable device (not shown in the figure, such as a mobile phone or a mouse) also belongs to the scope of the electronic device 100 having the waterproof structure in this embodiment. To facilitate understanding of the present invention, the electronic device 100 with a waterproof structure in this embodiment is described by taking the wearable device 100 as an example, and the wearable device 100 shown in the figure is a watch as an example.

The wearable device 100 includes a device body 1 , at least one control member 2 (eg, a knob or a button) movably mounted on the device body 1 , and an elastic member disposed between the device body 1 and the control member 2 3 and at least one gasket 4a, 4b. Wherein, one of the control members 2 is used as an example in this embodiment, and two washers 4a and 4b are used as an example in this embodiment, but not limited thereto.

The device body 1 includes a casing 11 and an optical detection module 12 disposed in the casing 11 . In this embodiment, the above-mentioned casing 11 is formed by assembling a plurality of components to surround and form a closed waterproof space S, and the casing 11 is provided with a light-transmitting area 111 . Wherein, an accommodating groove 112 is concavely formed on the outer edge of the casing 11 , and the light-transmitting area 111 is provided on the side wall of the accommodating groove 112 . That is, the light can pass through the light-transmitting area 111 and travel inside and outside the accommodating groove 112 .

The size of the light-transmitting area 111 can be adjusted according to the actual needs of the designer. For example, the minimum size of the light-transmitting area 111 is that the part of the casing 11 facing the optical detection module 12 is light-transmitting (as shown in FIG. 2A ), and the maximum size of the light-transmitting area 111 is that the casing 11 is all transparent. Translucent (not shown). Furthermore, the casing 11 is preferably made of a transparent material, such as polymethyl methacrylate (PMMA), polycarbonate (PC), or glass, so as to facilitate the above-mentioned casing 11 to be formed in accordance with the design. Various sizes of the light-transmitting area 111 required by the user.

The optical detection module 12 is disposed in the waterproof space S, and the optical detection module 12 faces the light-transmitting area 111 of the housing 11 . The optical detection module 12 includes a light-emitting unit 121 , a receiver array 122 adjacent to the light-emitting unit 121 , and an arithmetic unit 123 electrically connected to the receiver array 122 . The receiver array 122 and the computing unit 123 can also be collectively referred to as an optical navigation chip (not shown). Furthermore, the light emitting unit 121 , the receiver array 122 and the calculation unit 123 of the optical detection module 12 are a package structure in this embodiment, but the present invention is not limited thereto.

The light-emitting unit 121 is preferably a laser light-emitting diode chip 121 , and the light-transmitting area 111 is located on a light path of the light-emitting unit 121 , so that the light L emitted by the light-emitting unit 121 can pass through the light-transmitting area 111 . It penetrates out of the waterproof space S and enters into the accommodating groove 112 of the casing 11 . Furthermore, the light L in the accommodating groove 112 can also be reflected or refracted to enter the waterproof space S through the light-transmitting area 111 .

The receiver array 122 includes a plurality of receivers 1221 arranged in a matrix for receiving the light L passing through the light-transmitting area 111 and entering the waterproof space S. In addition, a retaining wall (not shown) is preferably provided between the receiver array 122 and the light-emitting unit 121, so as to achieve the effect of shielding the lateral light. Wherein, different receivers 1221 of the receiver array 122 can be used to receive light L of different angles, so that the calculation unit 123 can perform corresponding calculation according to the light L received by the receiver array 122 .

The control member 2 is movably mounted on the outer edge of the casing 11 and is located outside the waterproof space S, that is, the control member 2 is not structurally or electrically connected to the components in the casing 11 . (eg: the optical detection module 12 ), so that the wearable device 100 can be completely immersed in water to perform the operation of the manipulation member 2 and the detection of the optical detection module 12 .

Wherein, the manipulation member 2 is inserted into the accommodating groove 112 and at least partially corresponds to the light-transmitting area 111 . In addition, the wearable device 100 may not need any light guide components (eg, optical lenses) between the optical detection module 12 and the control member 2, that is to say, the light L emitted by the light emitting unit 121 can directly penetrate the light guide. Light-transmitting area 111 . Therefore, the light-emitting unit 121 can selectively emit light L that penetrates the light-transmitting area 111 and is projected onto the control member 2 , and then reflects the light L through the control member 2 to penetrate the light-transmitting area 111 and be received by the control member 2 . received by the receiver 1221 of the receiver array 122 .

Further, at least part of the manipulation member 2 corresponds to the light-transmitting area 111 and includes a feature portion 221 , that is, the portion of the manipulation member 2 corresponding to the light-transmitting area 111 (eg, located outside the feature portion 221 in FIG. 2B ) The partial block in the area surrounded by the imaginary line) is defined as the above-mentioned feature portion 221, and the manipulation member 2 can be in an initial position (as shown in FIG. 2B ) and an adjusted position (as shown in FIG. 3A or FIG. 4A ) relative to the light-transmitting area 111 . room activities.

The possible movement modes of the manipulation member 2 are illustrated in the following examples. The manipulation member 2 defines a central axis C, and the manipulation member 2 is substantially symmetrical to the central axis C. As shown in FIG. The manipulation member 2 can be selectively displaced along the central axis C and self-rotate with the central axis C as the axis, so that the manipulation member 2 can move between the initial position and the adjustment position relative to the light-transmitting area 111 . In other words, Fig. 3A shows the adjustment position of the control member 2 when the control member 2 is displaced along the central axis C; and Fig. 4A shows the adjustment position of the control member 2 when the control member 2 rotates with the central axis C as the axis .

Therefore, the light-emitting unit 121 can selectively emit light L to penetrate the light-transmitting area 111 and project it onto the control member 2 , and then reflect the light L through the control member 2 to penetrate the light-transmitting area 111 and be received. received by the device array 122 . The light L reflected by the feature portion 221 at the initial position and the adjusted position can be respectively received by different receivers 1221 in the receiver array 122 (as shown in FIG. 2C , FIG. 3B , and FIG. 4B ). Further, since the range that can be irradiated by light L corresponds to different receivers 1221 respectively, when the feature portion 221 moves within the range that can be irradiated by light L, the reflected light from the feature portion 221 at different positions Light L will be received by different receivers 1221 . Furthermore, the calculating unit 123 can calculate an active trajectory of the manipulation member 2 relative to the light-transmitting area 111 according to the light L received by each receiver 1221 in the receiver array 122 .

For example, the light L reflected by the feature 221 in the initial position shown in FIG. 2B is received by the receiver 1221a in FIG. 2C ; the light L reflected by the feature 221 in the adjusted position shown in FIG. 3A is received by the receiver 1221a in FIG. 2C . The light L reflected by the feature portion 221 in the adjusted position shown in FIG. 4A is received by the receiver 1221b in FIG. 3B , and received by the receiver 1221c in FIG. 4B . The calculating unit 123 can infer that the feature portion 221 moves to the left by a specific distance by comparing the receiver 1221a in FIG. 2C and the receiver 1221b in FIG. 3B ; or, the calculating unit 123 can compare the The receiver 1221a in 2C and the receiver 1221c in FIG. 4B can infer that the feature portion 221 is rotated upward by a certain angle.

It should be noted that, since the surface roughness of any object is not completely the same in the microscopic state, the outer surface roughness of the manipulation member 2 in this embodiment is also not completely the same. Therefore, in this embodiment, on the portion of the manipulation member 2 that the light L emitted by the light-emitting unit 121 can be projected onto (eg, the area surrounded by the imaginary line located outside the feature portion 221 in FIG. 2B ), there is no need to form any pattern , and only the feature portion 221 and the roughness difference between the peripheral blocks of the feature portion 221 are used to reflect different light rays L, so that the feature portion 221 can have the same effect as the existing grating, but the present invention is not limited to this. For example, in another not-shown embodiment, the outer surface of the manipulation member 2 may be formed with a plurality of different patterns (eg, gratings) for the calculation unit 123 to determine the movement trajectory of the manipulation member 2 .

In more detail, the control member 2 in this embodiment has a cylindrical control section 21 and a cylindrical actuation section 22 integrally connected to the control section 21 . The outer diameter of the control section 21 is larger than that of the actuation section 22 . , and the length of the manipulation section 21 is greater than the length of the actuation section 22 .

The elastic member 3 (eg, rubber pad) is disposed at the bottom of the accommodating groove 112 , the two washers 4a and 4b are sleeved on the actuating section 22 , and the actuating section 22 is passed through the accommodating groove 112 and abuts against it. It is connected to the elastic member 3 so as to provide a resilient force to the manipulation member 2 through the elastic member 3 , and the manipulation section 21 is exposed at least partially outside the accommodating groove 112 . Wherein, the opposite surfaces of the washer 4a abut against the control segment 21 and the housing 11 respectively (eg, the washer 4a is clamped between the control segment 21 and the housing 11 ), so that when the control segment 21 rotates relative to the housing 11 , the control section 21 can generate frictional force with the washer 4a. Furthermore, the gaskets 4 a and 4 b are both abutted against the housing 11 and the actuating section 22 to seal the accommodating groove 112 .

In addition, the present embodiment is described with two washers 4a and 4b, but the present invention is not limited thereto. For example, the above two washers 4a and 4b may also be integrally formed. Furthermore, in the present embodiment, the control member 2 takes the structure shown in FIG. 2A as an example, but other structures are not excluded. For example, the manipulation member 2 may also be a round rod, a disc, or a sliding rail (not shown in the figure).

In addition, although the device body 1 in this embodiment takes the optical detection module 12 disposed in the casing 11 as an example for illustration, the device body 1 can also be provided with other electronic components in the waterproof space S (Fig. not shown in ), which is not limited here. Alternatively, in the waterproof space S surrounded and formed by the casing 11 in this embodiment, only the above-mentioned optical detection module 12 may be provided. That is to say, the casing 11 , the optical detection module 12 and the control member 2 together form an optical encoder (not shown) with a waterproof function, and the optical encoder can be applied or installed in various electronic devices (Fig. not shown in).

[Example 2]

Please refer to FIG. 5 and FIG. 6 . The above-mentioned FIGS. 5 and 6 show the second embodiment of the present invention. The electronic device 100 (wearable device 100 ) with a waterproof structure provided in this embodiment is similar to the above-mentioned first embodiment. The same parts of the two embodiments will not be repeated, and the main differences between the two embodiments are roughly as follows.

The control member 2 of this embodiment forms a light guide path (not shown), and the control member 2 can receive an external light L' located outside the wearable device 100, so that the external light L' can advance along the light guide path and pass through The manipulation member 2 penetrates the light-transmitting area 111 and is projected to the receiver array 122 .

For example, the manipulation member 2 can be made of a light guide material, and the outer surface of the manipulation member 2 is plated with a reflective material, so that the inside of the manipulation member 2 is the light guide path. In addition, there are a plurality of blocks of different sizes on the outer surface of the control member 2 that are not coated with the above-mentioned reflective material, and the blocks are equivalent to a plurality of light exits 23 of different sizes of the light guide path. However, the specific implementation structure of the manipulation member 2 is not limited thereto. For example, as shown in FIG. 7 , the control member 2 can also form a circular light outlet 23 , the circular light outlet 23 is arranged around the control member 2 , and the center of the light outlet 23 is preferably located in the on the central axis C.

Accordingly, the manipulation member 2 can enable the received external light L′ to advance along the light guide path and pass through the manipulation member 2 from at least one of the light outlets 23 and penetrate the light-transmitting area 111 and projected onto the receiver array 122 . For example, the manipulation member 2 located at the initial position (as shown in FIG. 5 ) and the adjustment position (as shown in FIG. 6 ) can make the received external light L′ advance along the light guide path and respectively come out of the two light exits 23 (as shown in FIG. 6 ). 5 and FIG. 6 ) pass through the manipulation member 2 , and penetrate the above-mentioned light-transmitting area 111 to project to the receiver array 122 . Further, if the light spot formed after the external light L' passes through the light outlet 23 is smaller than or equal to the sensing range of the receiver array 122, the moving track of the manipulation member 2 can be identified by the light spot size and the moving track; The light spot formed after the light L' passes through the light outlet 23 is larger than the sensing range of the receiver array 122, so when the manipulation member 2 rotates, the movement of the manipulation member 2 can be identified according to the time when the light spot sweeps across the receiver array 122 trajectory.

Furthermore, the wearable device 100 of this embodiment can first turn off the light-emitting unit 121, and then judge the brightness of the surrounding environment through the intensity of the external light L' received by the receiver array 122. That is to say, if the light emitting unit 121 is turned off and the receiver array 122 still receives the external light L' of sufficient intensity, it means that the surrounding environment is bright.

In addition, when the wearable device 100 detects the brightness of the surrounding environment, the light-emitting unit 121 is turned off as a precondition, but the present invention is not limited to this. For example, the wearable device 100 may also be provided with different filter materials (not shown in the figure) on each receiver 122 of the receiver array 122, so that the wearable device 100 can adjust the brightness of the surrounding environment. During detection, it is not necessary to turn off the light-emitting unit 121 .
