[0057] In order to illustrate the technical solution of the present application, the following description is given with reference to specific drawings and embodiments.

[0058] In related technologies, the position of the lens cannot be effectively maintained. In some harsh environments (such as severe cold or heat), the lens will rotate and drive the knob to rotate, causing the image displayed by the lens to deflect, thereby affecting the normal use of the camera equipment.

[0059] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 This is a structural diagram of a camera device in one embodiment of the present application. Figure 2 yes Figure 1 The schematic diagram of the partial structure of the camera device shown in FIG. Figure 3 yes Figure 2 Exploded view of the camera device shown.

[0060] In a first aspect, an embodiment of the present application provides an adjustment device, including a housing 10, a bracket 20, a knob 30 and a limiting mechanism.

[0061] The bracket 20 is rotatably connected to the shell 10, and the bracket 20 is used to connect the lens 00; the knob 30 is rotatably connected to the shell 10, and the knob 30 can drive the bracket 20 to rotate relative to the shell 10; the limiting mechanism is used to limit the rotation of the bracket 20 relative to the shell 10.

[0062] Among them, the lens 00 and the bracket 20 rotate together relative to the shell 10, so when the bracket 20 is manually driven to rotate relative to the shell 10 by the knob 30, the lens 00 will also rotate synchronously relative to the shell 10, so that the shooting angle of the lens 00 can be manually adjusted. Moreover, after adjusting the shooting angle of the lens 00, the position of the lens 00 can be effectively maintained by limiting the rotation of the bracket 20 relative to the shell 10.

[0063] In the adjustment device provided in the embodiment of the present application, since the bracket 20 is rotatably connected to the housing 10, the bracket 20 is used to connect the lens 00, and the knob 30 is rotatably connected to the housing 10, the bracket 20 can be driven to rotate relative to the housing 10 by the knob 30, thereby adjusting the shooting angle of the lens 00, so that the lens 00 can rotate within a certain angle range, thereby enhancing the monitoring range and improving the user's sense of security. In addition, since the limit mechanism is used to limit the rotation of the bracket 20 relative to the housing 10, after adjusting the shooting angle of the lens 00, the limit mechanism can be used to limit the rotation of the bracket 20 relative to the housing 10, so that the position of the lens 00 can be effectively maintained, preventing the lens 00 from rotating and causing the image displayed by the lens 00 to deflect, thereby ensuring the normal use of the camera device.

[0064] The adjustment device provided in the embodiment of the present application can realize the rotation of the lens 00 within a range of 20 degrees by rotating the knob 30, thereby greatly increasing the monitoring range of the lens 00.

[0065] Optionally, the housing 10 includes a first shell 11 and a second shell 12 that are connected, and the bracket 20 and the limiting mechanism are both located in a space enclosed by the first shell 11 and the second shell 12 .

[0066] Please refer to Figure 4 , Figure 4 yes Figure 3 A partial enlarged view of point A in the middle.

[0067] In this embodiment, the bracket 20 includes a main body 21 and a rotating portion 22 connected to each other. The main body 21 is rotatably connected to the housing 10 via the rotating portion 22. The main body 21 is used to connect to the lens 00, and the knob 30 is connected to the rotating portion 22. This arrangement can more conveniently achieve a rotatable connection between the bracket 20 and the housing 10.

[0068] Optionally, two rotating parts 22 can be provided and the two rotating parts 22 are respectively provided at both ends of the main body 21. The rotating parts 22 can be provided as a columnar structure, and the knob 30 is connected to one of the rotating parts 22. Such a configuration can make the main body 21 more stable when rotating relative to the housing 10.

[0069] Please refer to Figure 5 、 Figure 6 and Figure 7 , Figure 5 yes Figure 3 A partial enlarged view of point B in the middle. Figure 6 yes Figure 2 The structural exploded view of the camera device from another perspective is shown. Figure 7 yes Figure 6 A partial enlarged view of point C in the middle.

[0070] Specifically, the limiting mechanism includes an elastic member 40 , a first limiting member 50 and a second limiting member 60 .

[0071] The shell 10 and the main body 21 are both connected to the elastic member 40, and the elastic member 40 is used to apply a first force to the main body 21 so that the main body 21 rotates around the rotating part 22, and the direction of the first force is along the first direction; one of the first limiting member 50 and the second limiting member 60 is connected to the shell 10, and the other of the first limiting member 50 and the second limiting member 60 is connected to the bracket 20, the first limiting member 50 is provided with a first limiting portion 51, and the second limiting member 60 is provided with a second limiting portion 61, and the second limiting portion 61 is engaged with the first limiting portion 51 to limit the main body 21 from rotating around the rotating part 22 relative to the shell 10 toward the second direction.

[0072] The first direction can be Figure 3 The direction indicated by the arrow K in the middle direction can be Figure 3 The direction indicated by the arrow L. For example, the first direction may be a counterclockwise direction around the rotating portion 22 , and the second direction may be a clockwise direction around the rotating portion 22 .

[0073] By adopting the above-mentioned solution, the structure of the limiting mechanism can be made simpler. It is only necessary to clamp and cooperate the second limiting portion 61 with the first limiting portion 51 to conveniently limit the main body 21 from rotating in the second direction relative to the shell 10 around the rotating portion 22, thereby ensuring the retention ability of the knob 30 in any environment, and preventing the lens 00 from rotating without the action of external force, thereby increasing the reliability of the camera equipment.

[0074] Furthermore, the second limiting portion 61 and the first limiting portion 51 engage in a locking manner to produce a mechanical feel and acoustic effect, which can provide strong user feedback so that the user knows that the knob 30 is rotated into place.

[0075] At the same time, the elastic member 40 strengthens the mechanical feedback of the knob 30 during the rotation process, so that the knob 30 has a soft and adjustable feel during the rotation process.

[0076] It is understood that both the first stopper 50 and the second stopper 60 can have a certain degree of elasticity. For example, the first stopper 50 and the second stopper 60 can be configured as cantilever structures. After the knob 30 drives the main body 21 to rotate a certain angle relative to the housing 10, the second stopper 61 engages with the first stopper 51 to prevent the bracket 20 from further rotating relative to the housing 10.

[0077] For example, the first limiting portion 51 may be configured as a protrusion, and the second limiting portion 61 may be configured as a groove. Alternatively, the first limiting portion 51 may be configured as a groove, and the second limiting portion 61 may be configured as a protrusion.

[0078] The elastic member 40 can be set as a torsion spring or a spring, etc., and a corresponding torsion spring mounting hole can be set on the bracket 20. During assembly, the torsion spring can be installed on the bracket 20 first, and then the bracket 20 is installed on the shell 10. A rib position that cooperates with the torsion spring can be set on the shell 10 to provide torque for the rotation of the torsion spring, that is, the torsion spring is fixed on the shell 10, and the torsion spring can rotate around its center line.

[0079] In order to enable the main body 21 to be driven to rotate to multiple angles relative to the shell 10 through the knob 30, in this embodiment, the second limiting member 60 is provided with multiple second limiting portions 61, and the multiple second limiting portions 61 are arranged at intervals around the rotating portion 22, and the first limiting portion 51 is detachably engaged with one of the second limiting portions 61.

[0080] By adopting the above solution, after the main body 21 is driven to rotate a certain angle relative to the housing 10 by the knob 30, the first limiting portion 51 engages with one of the second limiting portions 61 to restrict the bracket 20 from further rotating relative to the housing 10 in the absence of a significant external force. At this time, the main body 21 can be driven to further rotate relative to the housing 10 by rotating the knob 30, and both the first limiting portion 50 and the second limiting portion 60 will elastically deform, causing the first limiting portion 51 to engage with the other of the second limiting portions 61 to restrict the bracket 20 from further rotating relative to the housing 10 in the absence of a significant external force.

[0081] It can be understood that the multiple second limiting portions 61 can form a gear-like effect. During the rotation of the knob 30, the elastic member 40 provides torque, which creates a mechanical feel. Since there is no strong limit, the elastic member 40 will rebound, and the second limiting portion 61 cooperates with the first limiting portion 51 to provide forced limit, ensuring that the knob 30 will not have rotation problems in any environment. At the same time, the second limiting portion 61 and the first limiting portion 51 will have a sense of jamming during the rotation of the knob 30, providing mechanical and acoustic feedback.

[0082] Please refer to Figure 2 、 Figure 3 and Figure 4 In this embodiment, the knob 30 is provided with a first plug-in portion 31 , and the rotating portion 22 is provided with a first plug-in portion 221 . The first plug-in portion 221 is plugged into and matched with the first plug-in portion 31 .

[0083] By adopting the above solution, the knob 30 and the rotating portion 22 can be connected together more conveniently, and the knob 30 can drive the main body 21 to rotate through the rotating portion 22 .

[0084] It can be understood that the shapes of the first engaging portion 221 and the first connecting portion 31 can both be set to be non-rotating bodies, such as a cuboid or a cube.

[0085] For example, the first plug-in portion 31 may be configured as a protrusion, and the first plug-in portion 221 may be configured as a groove. Alternatively, the first plug-in portion 31 may be configured as a groove, and the first plug-in portion 221 may be configured as a protrusion.

[0086] Optionally, the limiting mechanism includes a first locking member 70, and the knob 30 and the rotating portion 22 are both detachably connected to the first locking member 70 to achieve connection between the knob 30 and the rotating portion 22. This arrangement can more conveniently achieve connection between the knob 30 and the rotating portion 22.

[0087] The first locking member 70 may be a buckle, a screw, a bolt, or the like.

[0088] For example, the rotating portion 22 is provided with a first locking hole 222, and the knob 30 is provided with a first mounting hole 32. The axis of the first locking hole 222 and the axis of the first mounting hole 32 are both parallel to the plugging direction of the first plugging portion 221 and the first plugging portion 31. The first locking member 70 is passed through the first locking hole 222 and the first mounting hole 32 to achieve detachable connection between the knob 30 and the rotating portion 22 and the first locking member 70. This configuration can make the structures of the knob 30 and the rotating portion 22 relatively simple, and facilitate the connection of the rotating portion 22 and the knob 30 together.

[0089] Specifically, the first locking member 70 may be a screw or a bolt. The first mounting hole 32 may pass through the first plug-in portion 31 , and the first locking hole 222 may pass through the first plug-in portion 221 .

[0090] Optionally, the adjustment device includes a seal 80 disposed between the rotating portion 22 and the knob 30. This arrangement ensures a high degree of sealing between the rotating portion 22 and the knob 30, meeting waterproof requirements. Furthermore, the seal 80 aids in tactile feedback when rotating the knob 30 relative to the housing 10.

[0091] Specifically, the sealing member 80 may be a sealing ring, which is sleeved on the first plug-in portion 31 or the first plug-fitting portion 221 .

[0092] Please refer to Figures 8 to 11 , Figure 8 is a structural diagram of a camera device in another embodiment of the present application, Figure 9 yes Figure 8 The schematic diagram of the partial structure of the camera device shown in FIG. Figure 10 yes Figure 9 An exploded view of the camera device shown, Figure 11 yes Figure 10 A partial enlarged view of point D in the middle.

[0093] Different from this embodiment, in another embodiment, the limiting mechanism includes a worm wheel 90 and a worm 100 , the worm wheel 90 is connected to the rotating part 22 ; the worm 100 is engaged with the worm wheel 90 , and the worm 100 is connected to the knob 30 .

[0094] By adopting the above scheme, the self-locking characteristics of the worm 100 when meshing with the worm wheel 90 can be utilized to prevent the worm wheel 90 from reversely driving the worm 100 to rotate, that is, the worm wheel 90 can be prevented from freely rotating relative to the worm 100, thereby limiting the rotation of the main body 21 and the rotating part 22 relative to the housing 10, and effectively maintaining the position of the lens 00.

[0095] It should be noted that the worm gear 90 and bracket 20 can be inserted into the shaft hole of the housing 10, and the worm 100 can be installed in the positioning hole of the housing 10 and locked with a screw to prevent the worm 100 from falling out. The knob 30 can be located at one end of the worm 100. Grease can be added to the worm gear 90 and worm 100 to achieve a smooth feel. Rotating the knob 30 located on the outside of the housing 10 at one end of the worm 100 can adjust the lens 00 up and down 40 degrees.

[0096] As can be understood, the large reduction ratio of 1:10 between the worm gear 90 and the worm 100 allows precise adjustment of the angle of the lens 00, i.e., for every 10-degree turn of the knob 30, the lens 00 rotates 1 degree. Furthermore, the self-locking nature of the worm gear 90 and the worm 100 ensures the positional reliability of the lens 00. That is, no matter how much torque the lens 00 is subjected to (within the maximum torque that would damage the housing 10), the lens 00 will not rotate. This provides a strong ability to maintain the position of the lens 00, thereby increasing the reliability of the imaging device.

[0097] Optionally, the worm gear 90 is provided with a second plug-in portion 91, and the rotating portion 22 is provided with a second plug-in portion 223, and the second plug-in portion 223 is plugged into and engaged with the second plug-in portion 91 along the axis of the worm gear 90. This arrangement can facilitate the connection between the worm gear 90 and the rotating portion 22, and can enable the worm gear 90 to drive the main portion 21 to rotate through the rotating portion 22.

[0098] For example, the second plug-in portion 91 can be configured as a protrusion, and the second plug-in portion 223 can be configured as a groove. Alternatively, the second plug-in portion 91 can be configured as a groove, and the second plug-in portion 223 can be configured as a protrusion. For example, the second plug-in portion 91 can be configured as a slot, and the second plug-in portion 223 can be configured as a raised rib.

[0099] The limiting mechanism includes a second locking member 110, and the rotating portion 22 and the worm gear 90 are both detachably connected to the second locking member 110 to connect the worm gear 90 to the rotating portion 22. This arrangement can more conveniently connect the worm gear 90 to the rotating portion 22.

[0100] For example, the second locking member 110 may be a buckle, a screw, a bolt, or the like.

[0101] Optionally, the rotating portion 22 is provided with a second locking hole 224, and the worm wheel 90 is provided with a second mounting hole 92. The axes of the second locking hole 224 and the second mounting hole 92 are both parallel to the axis of the worm wheel 90. The second locking member 110 is passed through the second locking hole 224 and the second mounting hole 92, so that the rotating portion 22 and the worm wheel 90 are both detachably connected to the second locking member 110. This configuration can simplify the structures of the worm wheel 90 and the rotating portion 22, and facilitates connecting the rotating portion 22 and the worm wheel 90 together.

[0102] Specifically, the second locking member 110 may be a screw or a bolt. The second mounting hole 92 may pass through the second plug-in portion 91 , and the second locking hole 224 may pass through the second plug-in portion 223 .

[0103] In a second aspect, an embodiment of the present application provides a camera device, comprising a lens 00 and an adjustment device as in the first aspect; the lens 00 is connected to a bracket 20 of the adjustment device.

[0104] In the camera device provided by the embodiment of the present application, since the bracket 20 is rotatably connected to the housing 10, the bracket 20 is used to connect the lens 00, and the knob 30 is rotatably connected to the housing 10, the bracket 20 can be driven to rotate relative to the housing 10 by the knob 30, thereby adjusting the shooting angle of the lens 00. In addition, since the limit mechanism is used to limit the rotation of the bracket 20 relative to the housing 10, after adjusting the shooting angle of the lens 00, the limit mechanism can be used to limit the rotation of the bracket 20 relative to the housing 10, so that the position of the lens 00 can be effectively maintained, preventing the lens 00 from rotating and causing the image displayed by the lens 00 to deflect, thereby ensuring the normal use of the camera device.
