Description

Technical Field

[0001] The present invention relates to the technical field of imaging devices, and in particular to an imaging device with adjustable imaging angle. Background Art

[0002] Nowadays, imaging equipment can be used in various scenarios, such as in rail transit vehicles and installed on the walls of the vehicles. In this application, the camera has a need for viewing angle orientation, and the viewing angle range of each car will be different. However, due to the size of the camera and the thinness of the wall, the camera angle cannot be adjusted in situ during installation and needs to be removed for adjustment. For example, directly turning the camera dome camera can easily cause the camera flip mechanism to occupy a large space. In addition, errors are very likely to occur during the removal and adjustment process, such as inaccurate viewing angle adjustment, and the removal and reinstallation process will cause the field of view to change.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] See also Figures 1 to 7 The present invention provides an imaging device with an adjustable imaging angle, which can be applied to any scene that requires image or video capture of the installed environment. It should be noted that, for ease of understanding, in the following embodiments, the imaging device with an adjustable imaging angle is defined as having front-to-back, lateral and longitudinal directions that are cross-set in pairs. Among them, the front side of the imaging device with an adjustable imaging angle mainly refers to the side facing the environment to be imaged, that is, the direction of the imaging surface 510.

[0043] Specifically, the imaging device with adjustable imaging angle includes a housing 110 , a movable seat 200 , an imaging module 500 and a driving mechanism. The rear end of the shell 110 is used to be installed on the carrier. The interior of the shell 110 is formed with an installation cavity with a front end opening 111. The shell 110 includes a first shell plate 112 located on one longitudinal side thereof; the movable seat 200 is arranged in the installation cavity and is flippably installed on the shell 110 around an axis extending in the transverse direction; the imaging module 500 is arranged in the installation cavity and is flippably installed on the movable seat 200 around an axis extending in the longitudinal direction, and at least the imaging surface 510 of the imaging module 500 is exposed from the opening 111; the driving mechanism includes an operating part, a first flip component 300 and a second flip component 400, the first flip component 300 is connected to the movable seat 200, and the second flip component 400 is connected to the imaging module 500, the operating part is at least partially exposed outside the shell 110, and is arranged at the first shell plate 112, and when the operating part is triggered, it drives the first flip component 300 to drive the movable seat 200 to flip, and / or drives the second flip component 400 to drive the imaging module 500 to flip.

[0044] In the technical solution provided by the present invention, by operating the operating part, the first flip component 300 can be triggered to adjust the movable seat 200 and the imaging module 500 to flip around the horizontal axis; the second flip component 400 can also be triggered to adjust the imaging module 500 to flip around the longitudinal axis, so that the orientation of the imaging surface 510 of the imaging module 500 can be flexibly adjusted, which is more suitable for meeting different imaging needs; since the rear end of the shell 110 is installed on a carrier such as a wall, and the operating part is exposed at the first shell plate 112 of the shell 110, the user's triggering action of the operating part and the installation of the shell 110 do not interfere with each other, which means that on the one hand, there is no need to disassemble the shell 110, and the imaging angle of the imaging module 500 can be adjusted while maintaining the installation state of the whole machine, which helps to reduce unnecessary adjustment errors and ensure the adjustment effect; on the other hand, the driving mechanism will not occupy too much space in the front and rear directions of the whole machine, which helps to make the size of the whole machine more reasonable and lightweight, and the installation between the carrier is more fitting and stable.

[0045] The shape, size, material, etc. of the housing 110 are not limited, but please consider Figure 1 to Figure 2 Specifically, a mounting cavity is formed inside the housing 110, so the housing 110 can be roughly in the shape of a hollow cuboid, and has a front housing plate, a rear housing plate, and four side housing plates connecting the front housing plate and the rear housing plate. The four side housing plates include two first housing plates 112 extending in the transverse direction and arranged opposite to each other in the longitudinal direction, and two second housing plates extending in the longitudinal direction and arranged opposite to each other in the transverse direction.

[0046] In practical applications, the rear shell of the housing 110 is used to be close to or close to the carrier to be installed. The carrier to be installed is, for example, a wall, a cabinet, a door, etc. Of course, this does not constitute a limitation on the specific connection position between the housing 110 and the carrier to be installed. Figure 1 As shown, the housing 110 may be provided with a lug structure protruding from the second shell plate, and then the housing 110 is stably mounted on the carrier to be mounted through the lug structure.

[0047] At least part of the front shell is provided with an opening 111 connected to the mounting cavity. The specific shape and size of the opening 111 are related to the lens, imaging surface 510, etc. in the imaging module 500, so as not to block the imaging range of the imaging module 500 too much.

[0048] In view of the above, the operating part of the driving mechanism is exposed on the first shell plate 112, and the imaging device with adjustable imaging angle is generally suspended at a high place of the body to be loaded. Therefore, generally, in practical applications, the longitudinal direction may correspond to the direction of gravity, and the first shell plate 112 provided with the operating part may specifically refer to the lower shell plate of the shell 110, so that the operating part is closer to the user, which is convenient for the user to manually trigger the operation.

[0049] Of course, the above does not constitute a limitation on the molding and installation methods of the front shell plate, the rear shell plate, the first shell plate 112, and the second shell plate in the housing 110. According to actual needs, the front shell plate, the rear shell plate, the first shell plate 112, and the second shell plate can be separately molded and then connected detachably or non-detachably; of course, at least two of the front shell plate, the rear shell plate, the first shell plate 112, and the second shell plate can also be obtained by integral molding.

[0050] The movable seat 200 is movably arranged in the installation cavity. It should be noted that the movable seat 200 can be directly movably installed with the housing 110, or Figures 2 to 4 As shown, the imaging device with adjustable imaging angle also includes a mounting base plate 120 and two mounting side plates 130. The mounting base plate 120 is fixedly mounted on the front wall of the mounting cavity and is hollowed out at the corresponding opening 111. The two mounting side plates 130 are arranged on the lateral sides of the mounting base plate 120. The mounting base plate 120 and the mounting side plates 130 can be integrally formed, or can be detachably or non-detachably connected after being separately formed. Among them, the mounting base plate 120 is easier to fit the inner wall of the mounting cavity, so that the mounting base plate 120 can be firmly supported by the shell 110. The mounting side plates 130 can lift the movable seat 200 away from the opening 111, thereby making way for a space for the movable seat 200 to be movably installed.

[0051] Next, the movable seat 200 is frame-shaped along the circumference of the opening 111, and includes two first brackets 210 extending in the horizontal direction and arranged oppositely in the longitudinal direction, and two second brackets 220 extending in the longitudinal direction and arranged oppositely in the horizontal direction. The middle parts of the two second brackets 220 are bent and extended in the front and rear directions to form second flanges 221, and the two second flanges 221 are respectively rotatably mounted on the two mounting side plates 130 through two first rotating shafts 230. The first rotating shaft 230 extends in the horizontal direction. The second flange 221 and the mounting side plate 130 on the corresponding side can fit as much as possible, and the plate-shaped setting helps to shorten the setting length of the first rotating shaft 230, thereby achieving the purpose of saving materials. In addition, the size of the first bracket 210 and the second bracket 220 in the movable seat 200 can be set to be no larger than the size of the mounting base plate 120 at the position, so that when flipped close, the mounting base plate 120 can form a stable support for the first bracket 210 and the second bracket 220, that is, the movable seat 200. The second flange 221 is arranged on the inner side of the mounting side plate 130. In this way, the mounting side plate 130 can form lateral limits on the second flange 221, that is, on the movable seat 200, so that the movable seat 200 has only the freedom of movement of flipping around the axis extending along the lateral direction relative to the mounting base plate 120 and the mounting side plate 130.

[0052] The imaging module 500 is a functional module that can achieve the imaging purpose, which can be, but is not limited to, an imaging device, an illumination device, a power supply device, etc. Among them, the imaging device is, for example, a camera that meets the requirements. The imaging surface 510 of the imaging device, that is, the imaging surface 510 of the imaging module 500, is generally exposed at the opening 111 as described above, and is arranged forward.

[0053] The imaging module 500 is integrally mounted on the movable seat 200. Specifically, the longitudinal sides of the imaging module 500 are respectively rotatably mounted on the movable seat 200 through two second rotating shafts 520. The second rotating shaft 520 is arranged to extend in the longitudinal direction. When the movable seat 200 includes two first brackets 210 and two second brackets 220 as described above, the two first brackets 210 can be provided with a flange structure as the first flange 211 described above, and then the imaging module 500 is rotatably connected to the flange structure through the above-mentioned second rotating shaft 520. Alternatively, the two first brackets 210 can be rotatably connected to the second rotating shaft 520 through an independently arranged mounting member, and then the second rotating shaft 520 is fixedly mounted on the corresponding side of the imaging module 500. Whether it is a flange structure or a mounting member, the imaging module 500 can be appropriately lifted away from the opening 111, thereby making way to reserve enough space for the imaging module 500 to flip relative to the movable seat 200 and the housing 110.

[0054] It should be noted that the above embodiments are all described by taking the middle part of the movable seat 200 as being rotatably mounted on the first rotating shaft 230 and the middle part of the imaging module 500 as being rotatably mounted on the second rotating shaft 520, so that during the process of adjusting the angle of the imaging module 500 by the driving mechanism, its rotation axis is set as close to the center as possible, so that when rotating, for example, around the transverse axis, it can be flipped in both positive and negative directions without occupying too much activity space. Of course, in other embodiments, the rotation axis of the movable seat 200 and / or the rotation axis of the imaging module 500 can be appropriately offset, for example, offset to the first bracket 210 of the movable seat 200, and / or offset to the position of the imaging module 500 close to the second bracket 220, etc., without limitation.

[0055] In view of the above, the driving mechanism can realize the driving of the flipping movement of the movable base 200 and the flipping movement of the imaging module 500 respectively.

[0056] Among them, the operating part is a structure that receives the initial external force, which is generally triggered by the user's manual operation, such as by pressing, pulling, rotating, or toggling by the user. Since the first flip assembly 300 is mainly used to transmit the external force received by the operating part to drive the movable seat 200 to flip around the transverse axis, the second flip assembly 400 is mainly used to transmit the external force received by the operating part to drive the imaging module 500 to flip around the longitudinal axis. Therefore, in actual application, the operating part can be set to one corresponding to the first flip assembly 300 and the second flip assembly 400 at the same time, and then distinguished by, for example, the size, duration, and frequency of the external force received. Alternatively, the operating part is provided with two corresponding to the first flip assembly 300 and the second flip assembly 400, and they are respectively the first operating part 330 provided corresponding to the first flip assembly 300 and the second operating part 430 provided corresponding to the second flip assembly 400. The first operating part 330 and the second operating part 430 are arranged adjacent to the first shell plate 112. In this way, both the first operating portion 330 and the second operating portion 430 can be directly close to the user, so that the user can operate the first operating portion 330 and the second operating portion 430 respectively according to actual needs without disassembling or turning over the housing 110 .

[0057] Furthermore, in one embodiment, the structures of the first operating part 330 and the second operating part 430 are at least partially differentiated. The differentiation is generally visible, that is, it can be visually distinguished by the user to avoid the situation where the first operating part 330 and the second operating part 430 have similar structures and cause adjustment errors. The structural differences between the two can be, but are not limited to, reflected in shape, size, logo, operation method, etc.

[0058] Specifically, please combine Figures 2 to 4The first shell plate 112 is longitudinally penetrated with an adjustment hole 113, and the adjustment hole 113 extends in an elongated shape in the front-to-back direction; the first flip assembly 300 includes a lever 310, and the lever 310 includes a first rod segment 311 extending into the installation cavity, and a second rod segment 312 extending from the adjustment hole 113 to the outside of the installation cavity. The first rod segment 311 is fixedly connected to the adjacent first bracket 210, and the second rod segment 312 can move along the adjustment hole 113 under the action of external force to lift or lower the first bracket 210, thereby forming a first operating part 330. Since the first rod segment 311 and the first bracket 210 are fixedly connected, when the user operates the second rod segment 312 (i.e., the first operating portion 330) to lift backward, the first bracket 210 connected to the first rod segment 311 is lifted up, and the other bracket is driven to descend, so that the imaging surface 510 of the imaging module 500 is deflected toward the side where the lever 310 is located; conversely, when the user operates the second rod segment 312 (i.e., the first operating portion 330) to descend forward, the first bracket 210 connected to the first rod segment 311 is driven to descend, and the other bracket is driven to lift up, so that the imaging surface 510 of the imaging module 500 is deflected toward the opposite side of the lever 310.

[0059] In order to enable the user to better operate the first operating part 330, at least the free end of the second rod segment 312 of the lever 310 can be set to a structure that is easy for the user to hold directly or pick up with a tool, for example, the size is larger than the first rod segment 311, the outer surface is provided with an anti-slip structure, the end is provided with a concave-convex structure, etc.

[0060] Next, in one embodiment, the middle portion of the first bracket 210 is bent and extended along the first shell plate 112 toward the front and rear directions to form a first flange 211, and the first flange 211 is longitudinally penetrated with a connecting hole 212; at least the first rod segment 311 is penetrated at the connecting hole 212 and is threadedly connected to the connecting hole 212, and the lateral dimension of at least part of the second rod segment 312 is greater than the width of the adjustment hole 113; the first flip assembly 300 also includes a locking nut 320, which is arranged on the side of the first flange 211 facing away from the first shell plate 112, and is threadedly connected to the protruding section of the first rod segment 311, so that when the lever 310 drives the movable seat 200 to flip to the target angle, it cooperates with the second rod segment 312 to lock the first flange 211 and the first shell plate 112. When the threaded connection between the first rod segment 311, the connection hole 212 and the locking nut 320 is appropriately weakened, the tightening degree between the first flange 211 and the first shell plate 112 is weakened, which facilitates the user to operate the first operating part 330 to lift or lower, and realize the flip adjustment of the movable seat 200 / imaging module 500. When the target angle is adjusted or no further adjustment is required due to other reasons, the threaded connection between the first rod segment 311, the connection hole 212 and the locking nut 320 can be appropriately increased, and the tightening degree between the first flange 211 and the first shell plate 112 can be increased, and then the current connection state can be locked.

[0061] In addition, please combine Figure 2 , Figures 5 to 7 The imaging module 500 includes a first side wall 530 located on one side of the first side wall 530 and extending in the longitudinal direction. The first side wall 530 extends obliquely in the longitudinal direction and is provided with a guide groove 540. The second flip assembly 400 includes a screw rod 410 and a guide nut 420. The screw rod 410 is located on one side of the first side wall 530 and extends in the longitudinal direction. The screw rod 410 is rotatably mounted on the movable seat 200 around its own axis. The guide nut 420 is threadedly connected and matched with the screw rod 410 so as to be driven by the screw rod 410 to translate in the longitudinal direction. The guide nut 420 is provided with a guide protrusion 421 protruding toward the first side wall 530. The guide protrusion 421 is slidably connected and matched with the guide groove 540. The first shell plate 112 may be provided with a mounting hole 114 in the longitudinal direction. A section of the screw rod 410 passes through the mounting hole 114 to the outside of the first shell plate 112 and can be rotated under the action of an external force to lift or lower the first side wall 530, thereby forming the second operating portion 430. The second operating portion 430 is configured to be a structure that facilitates the user to rotate the screw rod 410 manually or with the aid of a tool.

[0062] The guide groove 540 is tilted forward and backward along the longitudinal axis of the imaging module 500. Therefore, for ease of understanding, the rearmost position in the guide groove 540 is defined as the first position; the frontmost position in the guide groove 540 is defined as the second position; and the position in the guide groove 540 corresponding to the second rotating shaft 520 is the initial position. In this way, when the guide nut 420 is in the initial position, no force is applied to the first side wall 530, and the imaging surface 510 of the imaging module 500 is currently facing roughly forward. When the user drives the screw rod 410 to rotate forward by operating the second operating part 430, and drives the guide nut 420 to move from the initial position to the first position, a forward force is applied to the first side wall 530, driving the imaging surface 510 of the imaging module 500 to tilt in the direction away from the screw rod 410. Conversely, when the user operates the second operating part 430 to drive the screw 410 to rotate in the opposite direction and drive the guide nut 420 to move from the initial position toward the second position, a backward force is applied to the first side wall 530, driving the imaging surface 510 of the imaging module 500 to tilt toward the direction of the screw 410.

[0063] The extension length of the screw rod 410 is set to be not shorter than the extension length of the guide slot 540. In this way, the maximum moving distance of the guide protrusion 421 along the longitudinal direction can be not less than the length of the guide slot 540, so that the flip angle range of the imaging module 500 around the longitudinal axis can be increased as much as possible within the limited structural space.

[0064] The depth of the guide groove 540 is not less than half of the protruding height of the guide protrusion 421. In this way, the larger portion of the guide protrusion 421 can be inserted into the guide groove 540, and the outer surface of the guide protrusion 421 is in sliding contact with the inner surface of the guide groove 540, which helps to improve the sliding stability of the guide protrusion 421 during the sliding process relative to the guide groove 540, and prevents the guide protrusion 421 from slipping out of the guide groove 540 during the sliding process.

[0065] The outer surface of the guide protrusion 421 is spherical, and the inner surface of the guide groove 540 is adapted to the shape of the guide protrusion 421. On the one hand, the outer surface of the guide protrusion 421 and the inner surface of the guide groove 540 are adapted in shape and size as much as possible, so that the outer surface of the guide protrusion 421 fits the inner surface of the guide groove 540 as much as possible, thereby improving the stability of the sliding connection; on the other hand, combined with the above-mentioned associated setting of the groove depth of the guide groove 540 and the protruding height of the guide protrusion 421, the spherical guide protrusion 421 is more easily limited in the guide groove 540, further preventing the guide protrusion 421 from slipping out of the guide groove 540.

[0066] The first side wall 530 is configured in a convex arc shape for the flipping trajectory of the imaging module 500. That is, when the imaging module 500 has a longitudinal central axis, the first side wall 530 extends in an arc shape in a direction gradually approaching the screw rod 410 in the direction approaching the longitudinal central axis in the front-to-back direction. In this way, when the imaging module 500 flips forward and backward around the longitudinal axis, there is always a sufficient gap between the first side wall 530 and the screw rod 410 to avoid interference between the first side wall 530 and the screw rod 410.

[0067] Of course, in order to improve the stability of the movement of the guide nut 420 on the screw rod 410, in a further solution, the second flip assembly 400 may also include a guide rod and two support columns, the two support columns are convexly arranged on the second bracket 220 along the longitudinal interval, the guide rod is connected between the two support columns, and is arranged with the screw rod 410 along the lateral interval and extending along the longitudinal direction. The guide nut 420 is also provided with a guide hole along the longitudinal direction, and the guide hole is slidably connected and matched with the guide rod, so that the process of the guide nut 420 being driven by the screw rod 410 to move is more stable and the direction is accurate.

[0068] It should be noted that when the operating part is triggered by the user, the triggering external force can be directly transmitted to the first flip assembly 300 and / or the second flip assembly 400. Or in one embodiment, the driving mechanism also includes a driver and a switching component, and the switching component is respectively connected to the driver, the first flip assembly 300 and the second flip assembly 400; when the operating part is triggered, the triggering external force is manifested as triggering the driver to start running, and driving the switching component to connect the driver and the first flip assembly 300, and / or driving the switching component to connect the driver and the second flip assembly 400. At this time, the operating part can be set as one or two as described above. The switching component realizes the transmission of the driving force of the driver to the first flip assembly 300, and / or to the second flip assembly 400. For example, the driver can be a motor, and the switching component can be a transmission mechanism such as a gear set, a gear rack, a connecting rod mechanism, a rocker mechanism, etc.
