[0043] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0044] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0045] See also Figure 1 and Fig.14 Combined with Figure 2 and Figure 4 The present application discloses a multi-eye camera, which comprises a first transparent cover 1, a second transparent cover 2, a second lens assembly 3, at least two first lens assemblies 4 and a base 5.

[0046] Recombination Figure 6 , Figure 8 , Fig.10 , Fig.12 and Fig.13 Combined with Fig.11 The bottom of the first transparent cover 1 includes a mounting portion 11. The mounting portion 11 has a through mounting hole 110. The second transparent cover 2 is assembled to the mounting portion 11 and covers the mounting hole 110. Fig.14 Combined with Figure 1The second transparent cover 2, the first transparent cover 1 and the base 5 form a housing cavity for housing the second lens assembly 3 and a plurality of the first lens assemblies 4. Here, the shape of the first transparent cover 1 and the second transparent cover 2 after being assembled is not limited to the shape shown in the figure, and it only needs to achieve the functions described below.

[0047] See also Figure 1 , Figure 2 and Figure 4 Combined with Fig.14 At least two of the first lens assemblies 4 are arranged around the same axis 101, and the first transparent cover 1 is used to shoot the sideways image of the multi-eye camera. Based on this, the structures and numbers of the first transparent cover 1 and the first lens assemblies 4 are not limited, as long as they can shoot the sideways image of the multi-eye camera. For example, with respect to the number of the first lens assemblies 4, Figure 1 and Figure 2 As shown, there are four first lens assemblies 4. In other embodiments, there may be two, three, etc. first lens assemblies 4. In short, multiple first lens assemblies 4 can realize circumferential (such as 360-degree) photography of the multi-eye camera.

[0048] See also Figure 2 , Figure 3 , Figure 6 and Figure 7 Combined with Figure 1 and Fig.14 , the second lens assembly 3 is located on the axis 101, and the second transparent cover 2 is used to shoot the bottom of the multi-eye camera. There is no limit on how the second lens assembly 3 is located on the axis 101. For example, the second lens assembly 3 is hoisted at the center of the base 5, and the center is located on the axis 101. Therefore, the second lens assembly 3 is located on the axis 101. Figure 6 and Figure 7 Combined with Figure 5 and Figure 4 , one implementation method of hoisting is as follows: a countersunk hole 50 is provided at the center of the base 5. The second lens assembly 3 includes a connecting member 52. The connecting member 52 includes two sections, a first connecting member 521 and a second connecting member 522. However, in other implementations, the connecting member 52 may also have only one section, and is not limited to one section or two sections. There is a connecting portion 5211 on the connecting member 52. Screw holes are provided at the bottom of the countersunk hole 50 and the bottom of the connecting portion 5211. The connecting portion 5211 is connected to the countersunk hole 50 by a first screw 5212 passing through the screw hole, whereby the connecting member 52 is connected to the base 5. The second lens assembly 3 is assembled on the end of the connecting member 52 away from the base 5, so that the hoisting of the second lens assembly 3 is realized, and it is located on the axis 101. For example, Figure 6 and Figure 7It is shown that the lens holder assembly 31 of the second lens assembly 3 is assembled to the connecting member 52 (second connecting member 522) by the second screw 319, and on this basis, the second lens 32 is assembled to the lens holder assembly 31, so that the second lens assembly 3 is located on the axis 101. The lens holder assembly 31 includes a control board 311 and a lens holder 312. The lens holder 312 is connected to the connecting member 52 to clamp the control board 311. In other embodiments, the control board 311 can be assembled with the lens holder 312. The control board 311 is, for example, a PCB board including an image sensor (Sensor).

[0049] Of course, the aforementioned multiple first lens assemblies 4 taking pictures through the first transparent cover 1, and the second lens assembly 3 taking pictures through the second transparent cover 2, means that light can pass through the first transparent cover 1 and the second transparent cover 2 accordingly, and the camera function is still completed by the first lens assembly 4 and the second lens assembly 3.

[0050] For the above-mentioned multi-eye camera, for the integrated ball cover, the bottom of the ball cover (corresponding to the second transparent cover of the present application) cannot be made transparent due to process limitations. However, since the present application assembles the independent first transparent cover 1 and the second transparent cover 2 to form a transparent cover, it can be understood that the bottom of the integrated ball cover is cut off and the bottom of the integrated ball cover is replaced by the second transparent cover 2. Compared with the integrated ball cover, the manufacturing difficulty of the first transparent cover and the second transparent cover is low (that is, the manufacturing difficulty of the integrated ball cover is reduced), and the reliability of the first transparent cover and the second transparent cover is high (such as high transparency), ensuring that the camera quality of the second lens assembly 3 is good. For example, the camera quality in the range directly below is good because of the second transparent cover 2. In addition, the circumferential camera of the multi-eye camera is shot by the first lens assembly 4, and the bottom of the multi-eye camera is shot by the second lens assembly 3 at the same time. The combination of these two makes the monitoring field of the multi-eye camera wide, with few blind spots or no blind spots.

[0051] See also Fig.15 , Fig.10 , Fig.12 and Fig.13 Combined with Fig.14 and Figure 1 , the multi-eye camera includes a seal 6. The gap between the second transparent cover 2 and the mounting portion 11 is sealed by the seal 6, thereby isolating the interior of the accommodating cavity from the exterior of the multi-eye camera. The structure, material, etc. of the seal 6 are not limited, as long as they can achieve sealing. The material of the seal 6 is, for example, a silicone material. In this embodiment, the shapes of the first transparent cover 1 and the second transparent cover 2 are not limited to the shapes described later.

[0052] As configured above, by sealing the gap between the second transparent cover 2 and the mounting portion 11 with the seal 6, water or dust can be prevented from entering the accommodating cavity, thereby protecting the components of the multi-eye camera located in the accommodating cavity.

[0053] See also Fig.15 , Fig.13 , Figure 1 and Fig.10 Combined with Fig.12 , Fig. 9 and Fig.14 , the periphery 21 of the second transparent cover 2 is wrapped by the sealing member 6; the multi-eye camera includes a pressure ring 7, which is connected to the first transparent cover 1 and presses the sealing member 6 to seal the mounting hole 110. There is no limit to how the pressure ring 7 is connected to the first transparent cover 1. For example, screw holes are evenly spaced on the pressure ring 7 and the mounting portion 11; the pressure ring 7 is connected to the first transparent cover 1 by screws 71 passing through the screw holes, and at the same time, the locking force of the screws 71 presses the sealing member 6. Compare Fig. 9 and Fig.13 It can be seen that the pressure ring 7 presses the sealing member 6 tightly.

[0054] As described above, the pressure ring 7 is connected to the first transparent cover 1 to compress the sealing member 6, which is convenient for sealing and has a better sealing effect. Furthermore, the edge of the second transparent cover 2 is wrapped by the sealing member 6 to form a U-shaped seal, which ensures a good sealing effect while the edge of the second transparent cover 2 will not be crushed.

[0055] See also Fig.13 , Fig.11 and Fig.10 The inner wall of the mounting hole 110 is provided with a circle of bosses 112. The circle of bosses 112 may be a continuous structure along the mounting hole 110, or a plurality of bosses 112 may be distributed at intervals in the circumferential direction of the mounting hole 110 to form a circle. Of course, in this case, the intervals between adjacent bosses 112 must meet the sealing requirements. Fig.18 and Fig.19 as well as Fig.10 , Fig.13 and Fig.15 The sealing member 6 includes a sealing ring 61 that wraps around the periphery of the second transparent cover 2 , and the sealing ring 61 is pressed against the boss 112 by the pressing ring 7 , so that the pressing ring 7 presses the sealing member 6 .

[0056] As set up as above, since the boss 112 is located on the inner wall of the mounting hole 110, not only the boss 112 and a section of the inner wall of the mounting hole 110 located above the boss 112 can be sealed and contacted with the sealing ring 61, thereby increasing the contact area and achieving a better sealing effect; in addition, the boss 112 is located in the mounting hole 110 and can also play a positioning role in the installation of the seal 6, thereby facilitating the installation of the seal 6.

[0057] The above-mentioned sealing method for the second transparent cover 2 is not limited to the second transparent cover 2 of the structure described later, and can be applied to the second transparent cover 2 of any structure.

[0058] See also Fig.15 and Figure 5 Combined with Figure 6 , Figure 7 and Figure 3 The second lens assembly 3 includes a lens holder assembly 31 and a second lens 32 assembled with the lens holder assembly 31. The structure of the second lens 32 is not limited, for example, a fisheye lens. Fig.15 , Fig.13 , Fig.12 , Figure 8 and Fig.10 Combined with Fig. 9 , Fig.12 and Fig.14 The second transparent cover 2 includes a hollow cover body 22 extending out of the mounting hole 110. At this time, the structure of the cover body 22 is not limited to the structure described below, as long as the second lens assembly 3 can achieve photography through the cover body 22. Fig.18 and Fig.19 as well as Fig.10 , Fig.13 and Fig.15 , the sealing member 6 includes a shielding portion 62 located in the cover body 22. The shielding portion 62 includes an outlet 621. In the embodiment of the present application, the shielding portion 62 is connected to the sealing ring 61. The lens holder assembly 31 is shielded by the shielding portion 62. The second lens 32 extends from the shielding portion 62 from the outlet 621 and is located between the shielding portion 62 and the cover body 22 of the second transparent cover 2, and the second lens 32 is clearance-matched with the outlet 621. It should be noted here that: according to Fig.13 and Fig.15 Knowable Fig.10 In the process, the second transparent cover 2 should be located between the sealing member 6 and the first transparent cover 1. Fig.10 When the exploded view is shown, the second transparent cover 2 is placed between the pressure ring 7 and the sealing member 6, and the position relationship is as follows: Fig.13 and Fig.15 shall prevail.

[0059] As described above, the lens holder assembly 31 is shielded by the shielding portion 62 and the second lens 32 is located between the shielding portion 62 and the cover body 22 of the second transparent cover 2, so that only the second lens 32 can be seen from the outside of the multi-eye camera, thereby, the seal 6 also plays a decorative role, and the multi-eye camera is more beautiful. In addition, by the clearance fit between the second lens 32 and the outlet 621, it can also ensure that the second lens 32 and the shielding portion 62 of the seal 6 do not rub against each other, and ensure that the second lens 32 will not be damaged, etc. Finally, the sealing function and the decorative function are integrated in the seal 6, which also reduces the parts of the multi-eye camera and simplifies assembly.

[0060] See also Fig.15 , Fig. 9 , Fig.13 and Fig.18 Combined with Fig.19 , Fig.10 , Fig.12 and Fig.14 The shielding portion 62 includes a through hole 622 having the outlet 621. The second lens 32 extends from the outlet 621. A plurality of reinforcing members 623 are disposed on the hole wall of the through hole 622, and the plurality of reinforcing members 623 are distributed along the circumference of the through hole 622.

[0061] As described above, by providing the reinforcing member 623, the strength of the shielding portion 62 is increased. When the sealing ring 61 of the sealing member 6 seals the gap between the second transparent cover 2 and the mounting portion 11, the shielding portion 62 is not easily deformed, thereby better playing the aforementioned shielding role and better ensuring the gap between the second lens 32 and the outlet 621.

[0062] For any of the above second lens assemblies 3, see Fig.15 , Fig.17 , Figure 1 , Fig.13 and Fig.13 Combined with Fig.16 , Fig.10 , Fig.11 , Figure 8 and Fig.14 The first transparent cover 1 includes a curved surface portion 12 surrounding the mounting portion 11; along the direction of the axis, the curved surface portion 12 protrudes relative to the mounting portion 11. The second transparent cover 2 includes a spherical cover body 22; and a mounting hole 110 extending from the cover body 22. In other embodiments, the second transparent cover 2 is planar and covers the mounting hole 110.

[0063] As described above, the integrated transparent cover (ball cover) with a complex curved surface is split into a first transparent cover 1 including the curved surface portion 12 and the mounting portion 11, wherein the curved surface portion 12 protrudes relative to the mounting portion 11, and a second transparent cover 2 of the structure, and the first transparent cover 1 and the second transparent cover 2 are assembled. In this way, the production difficulty of the integrated transparent cover (i.e., the ball cover) with a complex curved surface is reduced, and the reliability of the first transparent cover 1 and the second transparent cover 2 is high (for example, the transparency is high), ensuring that the camera quality of the second lens assembly 3 is good. For example, the camera quality in the range directly below is good due to the second transparent cover 2.

[0064] See also Figure 1 , Fig.12 and Fig.13 Combined with Figure 8 , Fig.10 and Fig.14 In the case where the second transparent cover 2 includes a cover body 22 having a spherical surface, the multi-eye camera includes a decorative ring 8, which is inserted between the curved surface portion 12 and the cover body 22 and is fixedly connected to the mounting portion 11. The structure of the decorative ring 8 is not limited as long as it can play the role described above.

[0065] As set up above, since the cover body 22 of the second transparent cover 2 is spherical, it is a ball cover. In combination with the decorative ring 8 being inserted between the curved surface portion 12 and the cover body 22 and fixedly connected to the mounting portion 11, the decorative ring 8 improves the aesthetics of the multi-eye camera. In addition, by inserting the decorative ring 8 between the curved surface portion 12 and the cover body 22, it is only necessary to insert the decorative ring 8, and the assembly of the decorative ring 8 is convenient.

[0066] See also Fig.13 Combined with Fig.15 The mounting portion 11 includes an outer surface 111. The outer surface 111 refers to a surface located outside the multi-eye camera. The outer surface 111 is a plane, and the outer surface 111 is adhered to the decorative ring 8.

[0067] As described above, since the outer surface 111 of the mounting portion 11 is bonded to the decorative ring 8 , a fixed connection between the decorative ring 8 and the mounting portion 11 is achieved, and the connection is convenient and firm.

[0068] See also Fig.13 and Fig.10 Combined with Fig.15 The decorative ring 8 includes a decorative ring inner side 81 and a decorative ring outer side 82. The decorative ring inner side 81 is designed to conform to and fit closely with the outer surface of the cover body 22; the decorative ring outer side 82 is designed to conform to and fit closely with the outer surface of the curved surface portion 12.

[0069] As set up above, through the contour design and fit, during the installation of the decorative ring 8, it is only necessary to put the decorative ring 8 between the cover body 22 and the curved surface portion 12, and use the contour design to achieve positioning and fit, thereby achieving accurate positioning and facilitating assembly of the decorative ring 8.

[0070] For any of the above multi-view cameras, see Figure 5 Combined with Figure 4 , the base 5 includes a main board 51, and the multi-eye camera includes a connector 52 suspended from the base 5 and located on the axis 101. The second lens assembly 3 includes a lens holder assembly 31 for video recording. The opposite ends of the connector 52 are respectively connected to the base 5 and the second lens assembly 3. The cable of the second lens assembly 3 (to facilitate the distinction from the cable of the second lens assembly 3, the cable of the second lens assembly 3 is referred to as the second cable 33, and the cable of the first lens assembly 4 is referred to as the first cable 41) passes through the inside of the connector 52 and is electrically connected to the main board 51. Each cable (first cable 41) of the first lens assembly 4 is electrically connected to the main board 51 outside the connector 52. How to connect externally is not limited. It should be noted that for the middle eye connection cable and the lateral connection cable, the middle eye and lateral are added in front of the connection cable just for the purpose of distinction.

[0071] As configured above, the cable of the second lens assembly 3 (the second cable 33) passes through the inside of the connector 52 and is electrically connected to the main board 51, while the cable of each first lens assembly 4 (the first cable 41) is electrically connected to the main board 51 outside the connector 52. In this way, the cable of the first lens assembly 4 (the first cable 41) and the cable of the second lens assembly 3 (the second cable 33) are separated in space, and cable entanglement and the like will not occur.

[0072] See also Figure 5 Combined with Figure 4 , the connecting member 52 includes a connecting portion 5211. The connecting portion 5211 is connected to the base 5, and a first channel 5213 is formed between the connecting portion 5211 and the base 5. In other embodiments, the connecting portion 5211 itself has a first channel 5213. A second channel 5214 is formed between the mainboard 51 and the base 5. The cable (second cable 33) of the second lens assembly 3 passes through the first channel 5213 and the second channel 5214 in sequence and is electrically connected to the mainboard 51.

[0073] As configured above, the cable (second cable 33) can be better separated from the cable (first cable 41) in space, and cable entanglement and the like will not occur.

[0074] See also Figure 5 Combined with Figure 4 , and see Figure 7 Combined with Figure 6 , Figure 1 , Figure 2 and Fig.14 The base 5 includes a countersunk hole 50; the center of the countersunk hole 50 is located on the axis 101; the connecting portion 5211 is a flange, and the flange is assembled in the countersunk hole 50 by a first screw 5212.

[0075] As set up as above, since the center of the countersunk hole 50 is located on the axis 101, and the connecting portion 5211 is a flange and is located in the countersunk hole 50, it can be ensured that the second lens assembly 3 is located on the axis 101, and the connecting portion 5211 is located in the countersunk hole 50. Because of the obstruction of the side wall of the countersunk hole 50, the second lens assembly 3 can be prevented from tilting, etc., thereby ensuring the camera quality of the second lens assembly 3 and ensuring that the cable (second cable 33) is easy to route.

[0076] Second, combining Figure 1 , Figure 2 and Figure 4 The embodiment of the present application discloses a multi-eye camera. The multi-eye camera includes a base 5, a first transparent cover 1, at least two first lens assemblies 4 and a second lens assembly 3. The first transparent cover 1 includes a curved surface 12 and a mounting hole 110. The mounting hole 110 is located at the center of the curved surface 12, and the center of the mounting hole 110 is collinear with the center of the first transparent cover 1. At least two first lens assemblies 4 are arranged in a housing cavity formed by the first transparent cover 1 and the base 5, and the first lens assembly 4 can be pitched or horizontally rotated in the housing cavity, wherein the optical axis of the first lens assembly 4 intersects with the curved surface 12. The horizontal rotation of the first lens assembly 4 can be a circumferential horizontal rotation around the base 5, and the pitch can be achieved by assembling the first lens assembly 4 on the base 5 through a bracket and rotating around the bracket to achieve pitch. The second lens assembly 3 extends longitudinally, for example, along the axis 101. One end of the second lens assembly 3 is supported by the base 5 and the other end corresponds to the mounting hole 110, and the optical axis of the second lens assembly 3 is collinear with the center of the mounting hole 110.

[0077] As configured above, the multi-eye camera includes at least two first lens assemblies 4, which can be pitched or rotated horizontally, and also has a second lens assembly 3. This form of multi-eye camera further expands the monitoring field of view, especially the second lens assembly 3 can be used to monitor the middle area of ​​the monitoring field of view.

[0078] In some embodiments, in combination Figure 1 , Figure 4 and Figure 6 The center of the horizontal rotation trajectory of the first lens assembly 4 is collinear with the optical axis of the second lens assembly 3.

[0079] In some embodiments, see Fig.10 , Fig.13 and Fig.15 The multi-lens camera also includes a seal 6 and a second transparent cover 2. The second transparent cover 2 is sleeved on the outer surface of the seal 6. Fig.13 and Fig.15 Knowable Fig.10 In the process, the second transparent cover 2 should be located between the sealing member 6 and the first transparent cover 1. Fig.10 When the exploded view is shown, the second transparent cover 2 is placed between the pressure ring 7 and the sealing member 6, and the position relationship is as follows: Fig.13 and Fig.15 The sealing member 6 and the second transparent cover 2 are arranged in the mounting hole 110 so that the optical axis of the second lens assembly 3 intersects with the second transparent cover 2, wherein the second transparent cover 2 is spherical or flat.

[0080] As described above, the second transparent cover 2 is sleeved on the outer surface of the sealing member 6, and the sealing member 6 and the second transparent cover 2 are arranged in the mounting hole 110 so that the optical axis of the second lens assembly 3 intersects with the second transparent cover 2. On the one hand, the sealing member 6 seals the gap between the second transparent cover 2 and the mounting portion 11 to prevent water or dust from entering the cavity and protect the components of the multi-eye camera located in the cavity; on the other hand, the sealing member 6 plays a decorative role, and the related components of the second lens assembly 3 are not easily visible from the outer surface.

[0081] In some embodiments, see Fig.10 , Fig.12 , Fig.13 , Fig.15 , Fig.18 and Fig.19 The seal 6 is constructed as follows: the outer surface of the seal 6 is adapted to the inner surface shape of the second transparent cover 2, and the seal 6 has a through hole 622, and the aperture of the through hole 622 decreases along the optical axis direction.

[0082] As configured above, because the outer surface of the seal 6 is adapted to the shape of the inner surface of the second transparent cover 2, and the aperture of the through hole 622 decreases along the optical axis direction, the seal 6 can shield the relevant components of the second lens assembly 3 and play a decorative role, and the relevant components of the second lens assembly 3 are not easily visible from the outer surface.

[0083] See also Fig.11 , Fig.16 and Fig.17 The first transparent cover 1 is provided with a screw hole 120 on its inner surface adjacent to the mounting hole 110. Fig.13 and Fig.15 The multi-eye camera further includes a pressure ring 7, which is disposed adjacent to the second transparent cover 2. When the pressure ring 7 is locked via the screw hole 120, the seal 6 and the second transparent cover 2 jointly block the mounting hole 110.

[0084] As set above, the pressure ring 7 is locked with the screw hole 120 so that the sealing member 6 and the second transparent cover 2 jointly block the mounting hole 110 , and thus the locking force makes the sealing effect good.

[0085] In some embodiments, see Fig.17 , Fig.16 and Fig.13 , the extending direction of the screw hole 120 is the same as the optical axis direction of the second lens assembly 3. Fig.17 In the middle, they are all in the vertical upward direction.

[0086] In some embodiments, the screw holes 120 are circumferentially arranged in the vicinity of the mounting holes 110. Fig.16 and Fig.11 As shown, four screw holes 120 are arranged around the mounting hole 110. The screw holes 120 are integrally formed with the first transparent cover 1.

[0087] As configured above, the first transparent cover 1 is easy to manufacture due to the one-piece molding.

[0088] In some embodiments, see Figure 7 Combined with Figure 6 and Figure 5 The second lens assembly 3 includes a first connecting member 521 and a second connecting member 522, the first connecting member 521 and the second connecting member 522 are connected, and the cable (second cable 33) of the second lens assembly 3 is electrically connected to the mainboard 51 arranged on the base 5 via the first connecting member 521 and the second connecting member 522.

[0089] As configured above, since the cable (second cable 33) is electrically connected to the mainboard 51 via the first connector 521 and the second connector 522, the cable (first cable 41) of the first lens assembly 4 and the cable (second cable 33) of the second lens assembly 3 are spatially separated, and cable entanglement and the like will not occur.

[0090] See also Figure 5The image sensor 313 of the second lens assembly 3 is supported and assembled inside the second connecting member 522. The lens holder assembly 31 includes the image sensor 313. The second connecting member 522 is a bell-shaped mouth, and the image sensor 313 is located inside the bell-shaped mouth.
