It should be noted that the elements in each embodiment can be implemented using hardware (e.g., devices or circuits) or firmware (e.g., at least one program written in a microprocessor). Furthermore, the terms "first," "second," and similar descriptions in the following description are only used to define different elements, parameters, data, signals, or steps, and are not intended to limit their order. For example, the first device and the second device can be devices with the same structure but different from each other.

[0013] Figure 1 A top view of a protective cover 100 according to an embodiment of the present invention is shown. The protective cover 100 is used to protect a target element. This target element may be an image sensor, but it may also be other sensors or other electronic devices. Figure 1 As shown, the protective cover 100 includes a covering area CR, a first fixing area FR_1, a first connecting portion CP_1, a second fixing area FR_2, and a second connecting portion CP_2. The covering area CR is used to cover the target element. In one embodiment, the covering area CR may include a recessed area to accommodate the target element, thereby providing better protection. The first fixing area FR_1 includes a first hole H_1. The first connecting portion CP_1 is used to connect the first fixing area FR_1 and the covering area CR. The second fixing area FR_2 includes a second hole H_2. The second connecting portion CP_2 is used to connect the second fixing area FR_2 and the covering area CR. The first connecting portion CP_1 or the second connecting portion CP_2 is curved or has at least one bend. The protective cover 100 can be made of any material that can provide protection to the target element, such as acrylic.

[0014] In one embodiment, because it is curved or has a bend, the length of the first connecting portion CP_1 is greater than a shortest distance between the covering area CR and the first fixed area FR_1, and the length of the second connecting portion CP_2 is greater than a shortest distance between the covering area CR and the second fixed area FR_2. Figure 1 For example, the length of the first connecting part CP_1 is greater than the shortest distance D_1 between the coverage area CR and the first fixed area FR_1, while the length of the second connecting part CP_2 is greater than the shortest distance D_2 between the coverage area CR and the second fixed area FR_2.

[0015] Figure 2 It is illustrated Figure 1 The protective cover shown is a side view when used on an image sensor module. More specifically, Figure 2 It is illustrated Figure 1 The protective cover 100 shown is a side view taken from the X direction when used in an image sensor module. Figure 2 As shown, the image sensor module 200 includes Figure 1The diagram shows the coverage area CR, the first fixed area FR_1, the second fixed area FR_2, and the second connecting part CP_2. The first connecting part CP_1 is located in... Figure 2 It is not shown in the drawing. Figure 2 In the embodiments, except Figure 1 In addition to the components of the protective cover 100 shown, the image sensor module 200 further includes an image sensor 201, a substrate 203, a first fixing element FX_1, and a second fixing element FX_2. The image sensor 201 is located on the substrate 203. Figure 1 The first hole H_1 allows a first fixing element FX_1 to pass through, and the second hole H_2 allows a second fixing element FX_2 to pass through. Therefore, in Figure 2 In one embodiment, the first fixing element FX_1 passes through the first hole H_1 and the substrate 203, and the second fixing element FX_2 passes through the second hole H_2 and the substrate 203. The protective cover 100 can be fixed to the substrate 203 by means of the first fixing element FX_1 and the second fixing element FX_2. In one embodiment, the first fixing element FX_1 and the second fixing element FX_2 are screws, but this is not limited.

[0016] Please refer to this as well. Figure 1 as well as Figure 2 ,exist Figure 1 as well as Figure 2 In this embodiment, the first fixing element FX_1 is fixed to the substrate 203 through the first hole H_1 in the first fixing area FR_1, and the second fixing element FX_1 is fixed to the substrate 203 through the second hole H_2 in the second fixing area FR_2. Since the first fixing area FR_1 is connected to the first connecting portion CP_1 and the second fixing area FR_2 is connected to the second connecting portion CP_2, when an assembly force is applied to the first fixing element FX_1 to pass through the first hole H_1 and the substrate 203, the first connecting portion CP_1 will bear a component of this assembly force. If the length of the first connecting portion CP_1 is short (e.g., equal to the shortest distance D_1) and has no bends or curves, the first connecting portion CP_1 will bear excessive force and break or deform. Similarly, when the second fixing element FX_2 is subjected to an assembly force to pass through the second hole H_1 and the substrate 203, the second connecting part CP_2 will bear a component of this assembly force. If the length of the second connecting part CP_2 is short (e.g., equal to the shortest distance D_2) and has no bends or curves, the second connecting part CP_2 will bear excessive force and break or deform. Therefore, through Figure 1 as well as Figure 2 In some embodiments, the first connecting portion CP_1 and the second connecting portion CP_2 may have a longer length and have bends or bends, making them less likely to break or deform.

[0017] In one embodiment, when the first fixing element FX_1 is fixed to the substrate 203, it may deform, and when the second fixing element FX_1 is fixed to the substrate 203, it may deform. Therefore, in one embodiment, a gap may be reserved between the first fixing area FR_1 and the second fixing area FR_2 and the substrate 203 to allow for such deformation, but this is not a limitation.

[0018] As mentioned above, the first connecting portion CP_1 and the second connecting portion CP_2 may have a relatively long length. Therefore, when assembling the protective cover 100 to the substrate 203, the assembly stability may be poor. For example, the first fixing area FR_1 and the second fixing area FR_1 may slide, or even cause deformation of the protective cover 100. This utility model further provides a structure that can increase the stability of the protective cover 100 when it is assembled to the image sensor structure 200. Figure 3 A top perspective view of a protective cover according to another embodiment of the present invention is shown. Figure 4 A lower perspective view of the protective cover according to another embodiment of the present invention is shown. Figure 4 It can also be regarded as Figure 3 A diagram at the bottom. (See diagram below.) Figure 3 and Figure 4 As shown, the first fixed region FR_1 contains a columnar body PI_1, while the second fixed region FR_2 contains a columnar body PI_2. From Figure 4 The structural relationship between columnar bodies PI_1, PI_2 and the first fixed region FR_1 and the second fixed region FR_2 can be seen more clearly.

[0019] Figure 5 It is illustrated Figure 4 The protective cover shown is a side view in image sensing mode. More specifically, Figure 5 yes Figure 4 A side view taken from the Y direction. For example... Figure 5 As shown, the columnar body PI_2 is embedded in the substrate 203. This structure increases the assembly stability when assembling the protective cover 100 to the substrate 203. In this case, the aforementioned columnar bodies PI_1 and PI_2 can be regarded as positioners for the protective cover.

[0020] As mentioned above, the image sensor in this invention can be replaced by other sensors, therefore the aforementioned image sensor module can be regarded as a sensor module.
