[0075] For example, in an embodiment of the present application, the second camera 50 may further include a second lens decoration 520 , which may be installed on a side of the second photosensitive imaging component 52 facing the second lens window 515 .

[0076] Exemplarily, in an embodiment of the present application, the second camera 50 may further include a second fill light board 53, which may be fixedly mounted in the second body front cavity of the second camera 50 by a fixed connection with the body front shell assembly 51, and the second fill light board 53 is used to generate a fill light beam in a selected local area of ​​the target area covered by the lens field of view of the second photosensitive imaging assembly 52, so as to improve the image quality obtained by imaging by the second photosensitive imaging assembly 52.

[0079] Exemplarily, in an embodiment of the present application, the second camera 50 may further include a second motor 57, which may be fixedly mounted on the packaging cover plate 56, and the second motor 57 may be close to a side of the packaging cover plate 56 having a lateral plug-in shaft 567, the second assembly bracket 32 ​​of the adjustable assembly component 30 may have a transmission gear plate 37, the lateral drive shaft 567 may be coaxially plugged into the transmission gear plate 37, and the output shaft of the second motor 57 may utilize an output gear to engage with the transmission gear plate 37, so that the power output generated by the second motor 57 may drive the planetary motion of the second motor 57 relative to the transmission gear plate 37, and further, the second camera 50 may utilize the coaxial rotation of the hollow installation shaft 563 relative to the shaft support plate 33, and the coaxial rotation of the lateral plug-in shaft 567 relative to the transmission gear plate 37 to realize the pitch and tilt rotation adjustment within the clamping space between the first assembly bracket 31 and the second assembly bracket 32.

[0081] Figure 6 This is a schematic diagram of the wiring topology of the FPC of the camera assembly of the embodiment of the present application. Figure 6 In the embodiment of the present application, the camera assembly may further include an FPC 60, and the FPC 60 may be used to implement cross-body signal transmission between the first camera 10 and the second camera 50. Specifically, the cross-body signal transmission implemented by the FPC 60 may include cross-body signal transmission between the first body front cavity of the first camera 10 and the second body front cavity of the second camera 50. For example, in addition to implementing intra-cavity signal transmission with the first photosensitive imaging component 21 in the first body front cavity, the main circuit board 25 in the first body front cavity of the first camera 10 may also implement cross-body signal transmission with the second photosensitive imaging component 52 in the second body front cavity of the second camera 50 by using the FPC 60.

[0082] Exemplarily, in an embodiment of the present application, opposite ends of the FPC 60 respectively have a first FPC end segment and a second FPC end segment, the first FPC end segment of the FPC 60 can be located in the first body front cavity of the first camera 10, and the second FPC end segment of the FPC 60 can be located in the second body front cavity of the second camera 50, and the deployment path of the FPC 60 between the first body front cavity of the first camera 10 and the second body front cavity of the second camera 50 can be along the axial direction of the hollow adjustment main shaft 35 of the adjustable assembly component 30, penetrating the hollow adjustment main shaft 35 in a loose wiring state.

[0083] Exemplarily, in an embodiment of the present application, the front end baffle 112 of the first camera 10 may have a baffle wire passing hole 113, which is different from the perforations of the rear cavity cable 18 and the threading sealing plug 19 in the front end baffle 112 mentioned above. The axial direction of the baffle wire passing hole 113 intersects with the axial direction of the hollow adjustment spindle 35, and the baffle wire passing hole 113 is connected to the first body front cavity of the first camera 10, and the first FPC end section of the FPC 60 can pass through the baffle wire passing hole 113 and extend into the first body front cavity of the first camera 10; the hollow mounting shaft 563 of the packaging cover plate 56 of the second camera 50 is connected to the second body front cavity of the second camera 50, and the second FPC end section of the FPC 60 can extend into the second body front cavity of the second camera 50 along the axial direction of the hollow mounting shaft 563 through the hollow mounting shaft 563.

[0084] Exemplarily, in an embodiment of the present application, the first body rear cavity of the first camera 10 and the clamping space between the first assembly bracket 31 and the second assembly bracket 32 ​​of the adjustable assembly component 30 can be connected through the hollow adjustment main shaft 35 of the adjustable assembly component 30. In this case: when the FPC 60 is deployed through the hollow adjustment main shaft 35, it can also pass through the first body rear cavity of the first camera 10 and the first assembly bracket 31 and the second assembly bracket 32 ​​of the adjustable assembly component 30 outside the opposite ends of the hollow adjustment main shaft 35, respectively. The first FPC end section of the FPC 60 can extend from the first body rear cavity of the first camera 10 through the baffle wire hole 113 into the first body front cavity of the first camera 10, and the second FPC end section of the FPC 60 can extend from the clamping space between the first assembly bracket 31 and the second assembly bracket 32 ​​of the adjustable assembly component 30 through the hollow mounting shaft 563 into the second body front cavity of the second camera 50.

[0085] For example, in the embodiment of the present application, the FPC 60 in the first body rear cavity of the first camera 10 and the adjustable assembly component 30 in the clamping space between the first assembly bracket 31 and the second assembly bracket 32 ​​may be in a loose placement state.

[0086] For example, in the embodiment of the present application, the first FPC end section and the second FPC end section of the FPC 60 may have conductor terminals such as gold fingers for conductive connection, so that the first FPC end section and the second FPC end section of the FPC 60 may be connected to corresponding signal transceiver components in the first body front cavity of the first camera 10 and the second body front cavity of the second camera 50, respectively. For example, the conductor terminal of the first FPC end section of the FPC 60 may be electrically connected to the main circuit board 25 as a signal transceiver component in the first body front cavity of the first camera 10, and the conductor terminal of the second FPC end section of the FPC 60 may be electrically connected to the second photosensitive imaging component 52 of the signal transceiver component in the second body inner cavity of the second camera 50.

[0087] Based on the above embodiment of the present application, the camera assembly includes a first camera 10, and a second camera 50 mounted on the first camera 10 using an adjustable assembly assembly 30, the first camera 10 has a first body front cavity encapsulated by a front baffle 12, and the second camera 50 has a second body front cavity encapsulated by an encapsulation cover plate 56, and the rotation adjustment of the second camera 50 relative to the first camera 10 can be based on any one of the hollow adjustment main shaft 35 of the adjustable assembly assembly 30 and the hollow installation shaft 563 of the encapsulation cover plate 56 as the rotation axis. In this case, by inserting the opposite ends of the FPC 60 into the first body front cavity of the first camera 10 and the second body front cavity of the second camera 50 respectively, the cross-body signal transmission between the first camera 10 and the second camera 50 can be realized by using the FPC whose cost is lower than that of the slip ring line and the coaxial line, thereby reducing the wiring cost of the cross-body signal transmission in the camera assembly.

[0088] Moreover, in the embodiment of the present application, the FPC 60 is a thin sheet-like flexible plate body, which can tolerate bending or curling of 0-350° in the extension length direction, and the flexible plate body of the FPC 60 can also tolerate twisting of 0-90° with the extension length direction as the twisting axis. In this case, the angle range of the pitch angle adjustment achieved by the second camera 50 using the hollow mounting shaft 563 of the package cover plate 56 can be limited to the twisting tolerance angle of the flexible plate body of the FPC 60, and the angle range of the horizontal angle adjustment achieved by the second camera 50 using the hollow adjustment spindle 35 of the adjustable assembly component 30 may exceed the twisting tolerance angle of the flexible plate body of the FPC 60. In view of the above situation, the FPC 60 in the embodiment of the present application can be deployed in a loosely wired state through the hollow adjustment main shaft 35 of the adjustable assembly component 30. Therefore, it is possible to avoid the FPC 60 from being twisted beyond the torsion tolerance angle following the horizontal angle adjustment of the second camera 50. As a result, the two ends of the FPC 60 can be respectively inserted into the first body front cavity of the first camera 10 and the second front body front cavity of the second camera 50 for fixation, while the FPC 60 with limited torsional freedom can be avoided as much as possible from being twisted during the rotation adjustment (especially horizontal rotation adjustment) of the second camera 50.

[0089] For example, in the embodiment of the present application, the first body front cavity of the first camera 10 and the second body front cavity of the second camera 50 can be sealed cavities, that is, the front baffle 112 of the first camera 10 can seal and encapsulate the first body front cavity, and the sealing cover plate 56 of the second camera 50 can seal and encapsulate the second body front cavity. In this case, the first FPC end section of the FPC 60 can seal the baffle wire hole 113 penetrating the front baffle 112, and the second FPC end section of the FPC 60 can seal the hollow installation shaft 563 penetrating the encapsulation cover plate 56.

[0090] Illustratively, in an embodiment of the present application, the first FPC end section of the FPC 60 can be bent in the first body rear cavity of the first camera 10 and then extend through the baffle wire hole 113 into the first body front cavity of the first camera 10, and the second FPC end section of the FPC 60 can be bent in the clamping space between the first assembly bracket 31 and the second assembly bracket 32 ​​of the adjustable assembly component 30 and then extend through the hollow mounting shaft 563 into the second body front cavity of the second camera 50. Therefore, even if the FPC 60 is inevitably twisted in the hollow adjustment main shaft 35 of the adjustable assembly component 30, the bending structure can also prevent the twisting from being transmitted to the first FPC end section and the second FPC end section, thereby preventing the sealing penetration of the first FPC end section and the second FPC end section from loosening due to the twisting of the FPC 60 following the rotation adjustment of the second camera 50.

[0091] Exemplarily, in an embodiment of the present application, the bending position of the first FPC end section of the FPC 60 in the first body rear cavity of the first camera 10 can be located axially outside the end of the mounting column 115 inserted into the first body rear cavity of the first camera 10; the outer end opening of the hollow mounting shaft 563 of the packaging cover plate 56 facing away from the second body front cavity of the second camera 50 can have an axial gap with the first assembly bracket 31 (for example, the shaft support plate 33) of the adjustable assembly component 30, and the second FPC end section of the FPC 60 can pass through the hollow mounting shaft 563 through the axial gap, and the bending position of the second FPC end section of the FPC 60 in the clamping space can be located at the axial gap.

[0092] For example, in the embodiment of the present application, the sealing penetration of the first FPC end section of the FPC 60 in the baffle wire hole 113 of the front baffle 112 can adopt a mechanical seal; the sealing penetration of the second FPC end section of the FPC 60 in the hollow installation shaft 563 of the package cover plate 56 can adopt a glue-dispensing seal. If the first FPC end section and the second FPC end section of the FPC 60 both adopt the sealing method of glue-dispensing seal, then the first FPC end section and the second FPC end section of the FPC 60 are successively glue-dispensing sealed at the glue-dispensing station in the assembly line, thereby resulting in a longer sealing time for the whole camera assembly. Compared with the sealing method of glue-dispensing seal for the first FPC end section and the second FPC end section of the FPC 60, different sealing methods are adopted for the first FPC end section and the second FPC end section, which can support the two ends of the FPC 60 to be sealed synchronously at the glue-dispensing station and the assembly station, respectively, thereby saving the sealing time of the whole camera assembly.

[0093] Figure 7 Schematic diagram of the structure of an FPC used to realize signal transmission between a first camera and a second camera in a camera assembly according to an embodiment of the present application. Figure 8 It is a schematic diagram of the assembly relationship of the FPC of the camera assembly of the embodiment of the present application to achieve mechanical sealing at the first camera. Fig. 9 This is a schematic diagram of the sealing state of the FPC of the camera assembly of the embodiment of the present application realizing mechanical sealing at the first camera. Figures 7 to 9 While watching Figure 6 In an embodiment of the present application, the FPC 60 is integrally molded with a hard injection-molded plug 66. For example, the hard injection-molded plug 66 may include PVC (Polyvinylchloride). The FPC 60 may include a flexible circuit board and an outer sheath covering the flexible circuit board. Moreover, the hard injection-molded plug 66 may be injection-molded and bonded to the outer sheath of the FPC 60 using a high-temperature injection molding process.

[0094] For example, in the embodiment of the present application, the FPC 60 can penetrate the hard injection plug 66 along the axis of the hard injection plug 66, and the hard injection plug 66 is close to the first FPC end section of the FPC 60 at the injection position of the FPC 60. In this case, when the first FPC end section of the FPC 60 passes through the baffle wire hole 113 of the front baffle 112 of the first camera 10 and extends into the first body front cavity of the first camera 10, the hard injection plug 66 can be coaxially inserted into the baffle wire hole 113, and the hard injection plug 66 can use the sealing cooperation with the front baffle 112 to implement mechanical sealing on the baffle wire hole 113.

[0095] For example, in an embodiment of the present application, the hard injection plug 66 may include a plug-in plug 661, a sealing plug cap 662, and a mounting column 663 connected in sequence along the axial direction. For example, as shown in the diagram of the embodiment of the present application, the plug-in plug 661 and the mounting column 663 may be cylindrical with a length-to-diameter ratio greater than or equal to 0.5, and the sealing plug cap 662 may be disc-shaped with a length-to-diameter ratio less than 0.5. For example, the axial length L1 of the plug-in plug 661 may be 12±0.1 mm, and the outer diameter φ1 of the plug-in plug 661 may be 11.4±0.1 mm. For another example, the axial length L2 of the sealing plug cap 662 may be 1.3+0.1 mm, and the outer diameter φ2 of the sealing plug cap 662 may be 14.7±0.1 mm. For another example, the axial length L3 of the mounting column 663 may be 6.2±0.1 mm, and the outer diameter φ3 of the mounting column 663 may be 8±0.1 mm.

[0096] For example, in the embodiment of the present application, the sealing plug cap 662 is located at the first column end of the plug post 661 in the axial direction of the hard injection molded plug 66, and the sealing plug cap 662 radially protrudes outward relative to the plug post 661 in the radial direction of the hard injection molded plug 66, that is, the radial dimension of the sealing plug cap 662 is greater than the radial dimension of the plug post 661. For example, the outer diameter φ1 of the plug post 661 can be 11.4±0.1 mm, and the outer diameter φ2 of the sealing plug cap 662 can be 14.7±0.1 mm.

[0097] Exemplarily, in an embodiment of the present application, the mounting column 663 protrudes axially outward from the side of the sealing plug cap 662 facing away from the insertion plug column 661 in the axial direction of the hard injection molded plug 66, and the axial length and radial dimensions of the mounting column 663 can be smaller than those of the insertion plug column 661.

[0098] Illustratively, in the embodiment of the present application, the FPC 60 continuously penetrates the insertion plug column 661, the sealing plug cap 662 and the mounting column platform 663 along the axis of the hard injection-molded plug 66, the insertion plug column 661, the sealing plug cap 662 and the mounting column platform 663 are all injection-molded and bonded to the FPC 60 (i.e., the outer shell of the FPC 60), and the first FPC end section of the FPC 60 extends from the second column end of the insertion plug column 661 facing away from the sealing plug cap 662 and the mounting column platform 663.

[0099] For example, in the embodiment of the present application, when the first FPC end section of the FPC 60 passes through the baffle wire hole 113 of the front baffle 112 of the first camera 10 and extends into the first body front cavity of the first camera 10, the plug-in plug 661 is inserted into the baffle wire hole 113, and the assembly seal ring 65 sleeved on the plug-in plug 661 is squeezed between the sealing plug cap 662 and the rear wall surface of the front baffle 112 facing away from the first body front cavity of the first camera 10. For example, the assembly seal ring 65 can be a rubber ring. For another example, the outer peripheral surface of the first column end of the plug-in plug 661 connected to the sealing plug cap 662 can have a positioning ring groove 665 adjacent to the sealing plug cap 662, and the assembly seal ring 65 sleeved on the plug-in plug 661 can be clamped in the positioning ring groove 665 in the axial direction of the hard injection plug 66.

[0100] For example, in the embodiment of the present application, when the first FPC end section of the FPC 60 passes through the baffle wire hole 113 of the front baffle 112 of the first camera 10 and extends into the first fuselage front cavity of the first camera 10, a sealing pressure ring 69 is sleeved on the outer periphery of the mounting column 663, and the sealing pressure ring 69 generates a fastening pressure toward the front baffle 112 on the sealing plug cap 662 through a fixed connection with the front baffle 112, so that a sealing fit is formed between the sealing plug cap 662 and the rear wall surface of the front baffle 112 by means of the assembly sealing ring 65. For example, the sealing pressure ring 69 may include stainless steel.

[0101] For example, in the embodiment of the present application, the sealing pressure ring 69 can be fixedly connected to the front baffle 112 by a connecting piece such as a screw, and in order to allow the connecting piece to avoid the sealing plug cap 662, the outer diameter of the sealing pressure ring 69 can be larger than the outer diameter of the sealing plug cap 662, so as to provide a radial space for the connecting piece to be inserted on the radial outer side of the sealing plug cap 662. For example, the outer diameter φ8 of the sealing pressure ring 69 can be 26 mm, and the outer diameter φ2 of the sealing plug cap 662 can be 14.7±0.1 mm.

[0102] For example, in the embodiment of the present application, the sealing ring 69 may have a ring notch 690, and the ring notch 690 is used to allow the sealing ring 69 to be disassembled and assembled on the mounting column 663 through radial elastic deformation. For example, the notch width w9 of the ring notch 690 may be 2 mm, and when the sealing ring 69 is sleeved on the outer periphery of the mounting column 663, the sealing ring 69 and the mounting column 663 are interference-fitted to provide anti-cracking protection for the injection molding bonding between the mounting column 663 and the FPC 60. For example, the inner diameter φ9 of the sealing ring 69 may be 9 mm, and the outer diameter φ3 of the mounting column 663 may be 8±0.1 mm.

[0103] For example, in the embodiment of the present application, the plug-in plug 661 may have a plug-in hole groove 666, which extends along the axial direction of the hard injection-molded plug 66, and the plug-in hole groove 666 extends from the second end of the plug-in plug 661 to the inside of the plug-in plug 661. That is, the axial depth of the plug-in hole groove 666 is less than the axial length of the plug-in plug 661, for example, the axial length L1 of the plug-in plug 661 may be 12±0.1 mm, and the axial depth L6 of the plug-in hole groove 666 may be 8±0.1 mm.

[0104] For example, in the embodiment of the present application, the first FPC end section of the FPC 60 extends from the bottom of the plug hole groove 666 inside the plug 661, through the plug hole groove 666, to the outside of the second end of the plug 661, and the sealant filled in the plug hole groove 666 seals the injection molding bonding interface between the plug 661 and the FPC 60 at the bottom of the plug hole groove 666. Therefore, even if there is a crack between the plug 661 and the FPC 60, the sealant filled in the plug hole groove 666 can still maintain the sealing characteristics between the plug 661 and the FPC 60.

[0105] Fig.10 Schematic diagram of the sealed assembly state of the FPC used in the camera assembly of the embodiment of the present application at the second camera. Fig.10 In an embodiment of the present application, the packaging cover plate 56 of the second camera 50 may also have a through-line glue dispensing groove 568, which is in the axial direction of the hollow mounting shaft 563, blocking the inner end opening of the hollow mounting shaft 563 toward the second body front cavity of the second camera 50, and the hollow mounting shaft 563 is connected to the second body front cavity of the second camera 50 through the through-line glue dispensing groove 568.

[0106] For example, in the embodiment of the present application, when the second FPC end section of the FPC 60 penetrates the hollow installation shaft 563 and extends into the second body front cavity of the second camera 50, the second FPC end section of the FPC 60 penetrates the groove cavity of the through-line glue dispensing groove 568 from the inner end opening of the hollow installation shaft 563 and extends into the second body front cavity of the second camera 50. In this case, the sealant filled in the groove cavity of the through-line glue dispensing groove 568 can fill and press the second FPC end section of the FPC 60 into the through-line glue dispensing groove 568, and the sealant filled in the groove cavity of the through-line glue dispensing groove 568 can also block the inner end opening of the hollow installation shaft 563 to implement glue dispensing sealing on the hollow installation shaft 563. Thus, even if the second FPC end section of the FPC 60 is subjected to a torque that may cause torsion, the filling and pressing performed by the sealant filled in the groove cavity of the through-line glue dispensing groove 568 may be sufficient to enable the second FPC end section to resist the torque, thereby reducing the failure risk of the glue dispensing seal implemented on the hollow mounting shaft 563, that is, improving the reliability of the glue dispensing seal implemented on the hollow mounting shaft 563.

[0107] Illustratively, in an embodiment of the present application, the through-line glue dispensing groove 568 of the packaging shell 56 of the second camera 50 may have a groove wall through-line notch 569 on one side of the groove wall facing away from the inner end opening of the hollow mounting shaft 563 . In this case, when the second FPC end section of the FPC 60 passes through the hollow mounting shaft 563 and extends into the second body front cavity of the second camera 50, the second FPC end section of the FPC 60 that passes through the groove cavity of the through-line glue dispensing groove 568 extends into the second body front cavity of the second camera 50 from the through-line notch 569 of the groove wall, and the through-line notch 569 of the groove wall is blocked by the glue blocking gate 63. The glue blocking gate 63 can limit the second FPC end section of the FPC 60 and press it to the bottom of the groove cavity of the through-line glue dispensing groove 568. Thus, the glue blocking gate 63 can make the second FPC end section of the FPC 60 withstand the filling and pressing of the sealant filled in the groove cavity of the through-line glue dispensing groove 568 at the bottom of the groove cavity, and cooperate with the filling and pressing of the sealant to strengthen the FPC The second FPC end section 60 has a torque resistance capability, and the glue blocking gate piece 63 can also keep the sealant filled in the groove cavity of the through-line glue dispensing groove 568 by the glue blocking gate piece 63 to seal the inner end opening of the hollow mounting shaft 563.

[0108] For example, in the embodiment of the present application, the outer end opening of the hollow installation shaft 563 facing away from the second body front cavity of the second camera 50 is also inserted with a shaft sealing plug 62, and the second FPC end section of the FPC 60 can be further inserted into the shaft sealing plug 62 when passing through the hollow installation shaft 563. The shaft sealing plug 62 seals and fills the gap between the second FPC end section of the FPC 60 and the outer end opening of the hollow installation shaft 563, and the shaft sealing plug 62 can also generate a rotation-stopping constraint to prevent the second FPC end section of the FPC 60 from twisting relative to the hollow installation shaft 563. Thus, the torque that the FPC 60 may bear can be further reduced and transmitted to the groove cavity of the through-line glue dispensing groove 568, and then, the ability of the second FPC end section to resist the torque can be further improved, so as to further improve the reliability of the glue dispensing seal implemented by the hollow installation shaft 563.
