[0036] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 is a front view of a binocular vision module provided in an embodiment of the present application, Figure 2 yes Figure 1 The binocular vision module may include a flexible circuit board 100 , a first image sensor 200 and a second image sensor 300 .

[0039] The flexible circuit board 100 in the binocular vision module may have a first area Q1 and a second area Q2 arranged along a first direction f1, and the flexible circuit board 100 may have a strip groove a1 located in the first area Q1.

[0040] The first image sensor 200 and the second image sensor 300 in the binocular vision module may be distributed in the first area Q1 and located on the same side of the flexible circuit board 100 , and the first image sensor 200 and the second image sensor 300 may be electrically connected to the flexible circuit board 100 .

[0041] Among them, the first image sensor 200 and the second image sensor 300 can be respectively located on both sides of the strip groove a1, and the first image sensor 200 and the second image sensor 300 can be respectively located on both sides of the strip groove a1, and the distance d1 between the optical axis center line of the first image sensor 200 and the optical axis center line of the second image sensor 300 is within a preset distance range.

[0042] In the embodiment of the present application, the first image sensor 200 and the second image sensor 300 in the binocular vision module are integrated on the flexible printed circuit 100 (English: Flexible Printed Circuit; abbreviated as: FPC). In this way, by bending the flexible printed circuit 100, the volume of the binocular vision module can be effectively reduced, so that the operator can use the binocular vision module to collect the image of the target object in a small space environment, thereby improving the flexibility and convenience of the binocular vision module. In addition, a strip groove a1 is opened on the first area Q1 of the flexible printed circuit 100. During the assembly of the binocular vision module, the operator can first attach the first image sensor 200 to one side of the strip groove a1. After that, the operator can quickly determine the basic installation position of the second image sensor 300 based on the strip groove a1, thereby ensuring that the distance between the optical axis center line of the first image sensor 200 and the optical axis center line of the second image sensor 300 is within a preset distance range. It should be noted that the setting of the strip groove a1 can isolate the first image sensor 200 and the second image sensor 300, effectively preventing signal interference between the first image sensor 200 and the second image sensor 300, and ultimately ensuring that the two image sensors have a high acquisition accuracy of the image signal of the target object, thereby ensuring that the binocular vision device integrated with the binocular vision module has a better imaging effect on the target object.

[0043] For example, in order to ensure the strength of the flexible circuit board 100 and the wiring area on the flexible circuit board 100, the width d2 of the strip groove a1 can range from 0.15 mm to 0.25 mm, for example, the width d2 of the strip groove a1 can be 0.2 mm. The preset distance between the optical axis center line of the first image sensor 200 and the optical axis center line of the second image sensor 300 can range from 3.77 mm to 3.83 mm, for example, the distance d1 between the optical axis center line of the first image sensor 200 and the optical axis center line of the second image sensor 300 can be 3.8 mm.

[0044] In summary, the embodiment of the present application provides a binocular vision module, which may include: a flexible circuit board, a first image sensor, and a second image sensor. By integrating the first image sensor and the second image sensor in the binocular vision module on the flexible circuit board, the volume of the binocular vision module can be effectively reduced by bending the flexible circuit board, so that the operator can use the binocular vision module to collect images of the target object in a small space environment, thereby improving the flexibility and convenience of the binocular vision module. In addition, a strip groove is opened on the first area of ​​the flexible circuit board. During the assembly of the binocular vision module, the operator can first attach the first image sensor to one side of the strip groove. After that, the operator can quickly determine the basic installation position of the second image sensor based on the strip groove, thereby ensuring that the distance between the optical axis center line of the first image sensor and the optical axis center line of the second image sensor is within a preset distance range. It should be noted that the setting of the strip groove can isolate the first image sensor from the second image sensor, effectively preventing signal interference between the first image sensor and the second image sensor, and ultimately ensuring that the two image sensors have high accuracy in collecting image signals of the target object, thereby ensuring that the binocular vision device integrated with the binocular vision module has a better imaging effect on the target object.

[0045] Optional, please refer to Figure 3 , Figure 3 : is a front view of another binocular vision module provided by an embodiment of the present application. The first image sensor 200 and the second image sensor 300 in the binocular vision module can be arranged along the second direction f2, and the length direction of the strip groove a1 can be parallel to the first direction f1. The strip groove a1 can have an open end and a blind end that are arranged oppositely, and the blind end of the strip groove a1 can be closer to the second area Q2 of the flexible circuit board 100 relative to the open end of the strip groove a1. Among them, the first direction f1 can be parallel to the direction of the short side of the flexible circuit board 100, and the second direction f2 can be parallel to the direction of the long side of the flexible circuit board 100. In this case, the first image sensor and the second image sensor 300 are arranged along the long side direction of the flexible circuit board 100, which can ensure the preset distance between the two image sensors and make full use of the layout space of the flexible circuit board 100. In addition, the extension direction of the strip groove a1 is parallel to the direction of the short side of the flexible circuit board 100, and the strip groove a1 has an open end and a blind end that are arranged oppositely, that is, the length of the strip groove a1 can be less than the width of the flexible circuit board 100. For example, the flexible circuit board 100 may be rectangular.

[0046] In the examples of this application, please refer to Figure 4 and Figure 5 , Figure 4is a front view of another binocular vision module provided in an embodiment of the present application, Figure 5 yes Figure 4 The bottom view of the binocular vision module is shown. The binocular vision module may also include: a first type of filter capacitor 400 and a second type of filter capacitor 500, both of which may be arranged on the flexible circuit board 100, and the first type of filter capacitor 400 may be arranged adjacent to the first image sensor 200, and the second type of filter capacitor 500 may be arranged adjacent to the second image sensor 300. The first type of filter capacitor 400 may be electrically connected to the first image sensor 200, and the first type of filter capacitor 400 may be used to filter the electrical signal that supplies power to the first image sensor 200; the second type of filter capacitor 500 may be electrically connected to the second image sensor 300, and the second type of filter capacitor 500 may be used to filter the electrical signal that supplies power to the second image sensor 300.

[0047] For example, during the operation of the first image sensor 200 and the second image sensor 300, a power supply (not shown in the figure) is required to power them, and the power supply signal of the power supply will affect the quality of the image signal collected by the image sensor. For example, the more stable the power supply signal is, the less noise there is in the image signal; the less stable the power supply signal is, the more noise there is in the image signal. In order to improve the quality of the collected image signal, it is necessary to optimize the power supply signal. Here, a first type of filter capacitor 400 is used to filter the power supply signal so that the power supply signal after filtering is more stable, so as to improve the quality of the image signal collected by the first image sensor 200; a second type of filter capacitor 500 is used to filter the power supply signal so that the power supply signal after filtering is more stable, so as to improve the quality of the image signal collected by the second image sensor 300.

[0048] Optional, such as Figure 4 and Figure 5As shown, the number of the first type of filter capacitors 400 in the binocular vision module can be multiple, a part of the first type of filter capacitors 400 can be located on the same side of the flexible circuit board 100 as the first image sensor 200, and another part of the first type of filter capacitors 400 can be located on the side of the flexible circuit board 100 away from the first image sensor 200. And the orthographic projection of a part of the first type of filter capacitors 400 on the flexible circuit board 100 and the orthographic projection of another part of the first type of filter capacitors 400 on the flexible circuit board 100 can be located on both sides of the orthographic projection of the first image sensor 200 on the flexible circuit board 100. The number of the second type of filter capacitors 500 in the binocular vision module can be multiple, a part of the second type of filter capacitors 500 and the second image sensor 300 can be located on the same side of the flexible circuit board 100, and another part of the second type of filter capacitors 500 can be located on the side of the flexible circuit board 100 away from the second image sensor 300. And the orthographic projection of a part of the second type of filter capacitor 500 on the flexible circuit board 100 and the orthographic projection of another part of the second type of filter capacitor 500 on the flexible circuit board 100 can be respectively located on both sides of the orthographic projection of the second image sensor 300 on the flexible circuit board 100. In this case, by arranging a plurality of first type of filter capacitors 400 near the first image sensor 200, a better filtering effect can be further obtained. Similarly, by arranging a plurality of second type of filter capacitors 500 near the second image sensor 300, a better filtering effect can be further obtained. In addition, a part of the first type of filter capacitor 400 and a part of the second type of filter capacitor 500 are both arranged on the side of the flexible circuit board 100 away from the first image sensor 200 and the second image sensor 300, so that electronic devices can be arranged on both sides of the flexible circuit board 100, ensuring that the flexible circuit board 100 can integrate more electronic devices and increase functional diversification.

[0049] For example, Figure 4 and Figure 5 As shown, a portion of the first type of filter capacitor 400 may include: filter capacitor C7 and filter capacitor C8, and another portion of the first type of filter capacitor 400 may include: filter capacitor C5 and filter capacitor C6. A portion of the second type of filter capacitor 500 may include: filter capacitor C1, filter capacitor C2 and filter capacitor C3, and another portion of the second type of filter capacitor 500 may include: filter capacitor C4.

[0050] In the embodiments of the present application, Figure 4As shown, the surface of the flexible circuit board 100 may have a first groove c1 corresponding to the first type of filter capacitor 400, and a second groove c2 corresponding to the second type of filter capacitor 500. Among them, at least part of the first type of filter capacitor 400 may be located in the first groove c1, and at least part of the second type of filter capacitor 500 may be located in the second groove c2. In this case, by opening the first groove c1 on the surface of the flexible circuit board 100, at least part of the first type of filter capacitor 400 is installed in the first groove c1; at the same time, the second groove c2 is opened on the surface of the flexible circuit board 100, and at least part of the second type of filter capacitor 500 is installed in the second groove c2. In this way, the thickness of the binocular vision module can be effectively reduced, and the overall volume of the binocular vision module can be further reduced.

[0051] Optional, please refer to Figure 6 , Figure 6It is a front view of another binocular vision module provided by an embodiment of the present application. The flexible circuit board 100 in the binocular vision module may include: a flexible circuit board body 101, a signal line 102 and a connection pad 103, one end of the signal line 102 may be electrically connected to the target image sensor, the other end of the signal line 102 may be electrically connected to the connection pad 103, and the connection pad 103 may be located at the edge of the flexible circuit board 100. The target image sensor may be one of the first image sensor 200 and the second image sensor 300. The flexible circuit board body 101 may have a first flat area P1, a second flat area P2, and an arc-shaped bending area P3 located between the first flat area P1 and the second flat area P2. The target image sensor may be located on the first flat area P1, the connection pad 103 may be located on the second flat area P2, a portion of the signal line 102 may be located in the first flat area P1, another portion of the signal line 102 may be located in the second flat area P2, and another portion of the signal line 102 may be located in the arc-shaped bending area P3. In which, when the flexible circuit board 100 is in a bent state, the portion of the signal line 102 located in the arc-shaped bending area P3 of the flexible circuit board body 101 can be arc-shaped. In this case, by providing the first flat area P1, the second flat area P2, and the arc-shaped bending area P3 located between the first flat area P1 and the second flat area P2 in the flexible circuit board body 101, when the operator needs to bend the flexible circuit board 100 for use, the flexible circuit board body 101 can be bent along the arc-shaped bending area P3, and the signal line 102 located in the arc-shaped bending area P3 can be arc-shaped, ensuring that the signal line 102 will not generate a large stress and break. For example, the flexible circuit board 100 may have an arc-shaped bending area P3, so that the flexible circuit board 100 can form an "L" shape after bending; or, the flexible circuit board 100 may have two arc-shaped bending areas P3 arranged along the first direction f1, so that the flexible circuit board 100 can be bent at the two arc-shaped bending areas P3, and the flexible circuit board 100 can form a "U" shape after bending.

[0052] For example, the flexible circuit board 100 may include two groups of connection pads 103, and the two groups of connection pads 103 are respectively electrically connected to the first image sensor 200 and the second image sensor 300. In addition, there are MIPI signal lines among the signal lines electrically connected to the target image sensor, and the MIPI signal lines need to be as long and equidistant as possible. The equal length is to ensure that the two differential signals of the MIPI signal line can reach the receiving end at the same time, and the equidistant is to ensure a certain degree of coupling.

The flexible circuit board body 101 may also have a heat dissipation protection layer 101a, which may be coated on the arc-shaped bending area P3 of the flexible circuit board body 101. For example, the heat dissipation protection layer 101a may be located on the same side of the flexible circuit board body 101 as the first image sensor 200 and the second image sensor 300, or the heat dissipation protection layer 101a may be located on the side of the flexible circuit board body 101 away from the first image sensor 200 and the second image sensor 300. In this case, by providing the heat dissipation protection layer 101a on the arc-shaped bending area P3 of the flexible circuit board body 101, the heat dissipation protection layer 101a can enhance the strength of the arc-shaped bending area P3 of the flexible circuit board body 101, and ensure that the flexible circuit board body 101 will not break when it is bent at the arc-shaped bending area P3. In addition, the heat generated by the operation of the electronic components on the flexible circuit board 100 can be conducted to the flexible circuit board, and the heat dissipation protection layer 101a can absorb the heat in the flexible circuit board, thereby ensuring a longer working life of the flexible circuit board.

[0054] In the present application, the heat dissipation protection layer 101a may include: any one of a metal heat dissipation layer, a thermal conductive adhesive and a thermal conductive foam.

By integrating the first image sensor and the second image sensor in the binocular vision module on the flexible circuit board, the volume of the binocular vision module can be effectively reduced by bending the flexible circuit board, so that the operator can use the binocular vision module to collect images of the target object in a small space environment, thereby improving the flexibility and convenience of the binocular vision module. In addition, a strip groove is opened on the first area of ​​the flexible circuit board. During the assembly of the binocular vision module, the operator can first attach the first image sensor to one side of the strip groove. After that, the operator can quickly determine the basic installation position of the second image sensor based on the strip groove, thereby ensuring that the distance between the optical axis center line of the first image sensor and the optical axis center line of the second image sensor is within a preset distance range. It should be noted that the setting of the strip groove can isolate the first image sensor from the second image sensor, effectively preventing signal interference between the first image sensor and the second image sensor, and ultimately ensuring that the two image sensors have high accuracy in collecting image signals of the target object, thereby ensuring that the binocular vision device integrated with the binocular vision module has a better imaging effect on the target object.
