Description

Technical Field

[0001] This invention relates to the field of lens caps for imaging devices, specifically to an imaging device and its lens cap assembly. Background Technology

[0002] A lens cap is an important accessory used to protect the lens of an imaging device. Its main function is to cover the front and rear lens elements of the lens when it is not in use, so as to prevent dust, moisture or accidental impacts from damaging the lens.

[0003] Existing imaging equipment lens caps use a locking block that extends and retracts along the diameter in conjunction with a spring. After the locking block slides in opposite directions, the lens cap is aligned with the lens of the imaging equipment and then released. The locking block is then reset by the spring force and locks the edge of the imaging equipment lens, thus completing the installation of the lens cap. The same principle applies when you want to remove the lens cap.

[0004] Chinese patent CN206039114U discloses an imaging device lens cover assembly, including a lens cover body and a fixing component, which is disposed on the lens cover body and is detachably fixed to the outer shell of the imaging device.

[0005] Regarding the aforementioned technologies, existing lens caps for imaging devices are easily lost after removal. If a thin string is used to connect the lens cap to the imaging device, the movement of the lens cap can easily affect the normal operation of the imaging device. Furthermore, existing lens caps have poor sealing performance after being attached to the lens of the imaging device, allowing external dust and water to easily pass through the lens cap and contaminate the lens. Additionally, after the lens cap is removed, the side of the lens cap facing the lens is also easily contaminated, which can then contaminate the lens of the imaging device when the lens cap is connected. In summary, existing lens cap assemblies for imaging devices do not provide adequate protection for the lens of the imaging device while ensuring easy storage. Summary of the Invention

[0006] Based on this, the purpose of the present invention is to provide an imaging device and its lens cover assembly, so as to solve the technical problem that existing imaging device lens cover assemblies are not easy to protect the lens of the imaging device while being easy to store.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a lens cover assembly for an imaging device, comprising a housing, the housing being fixedly connected to the imaging device, and having an opening at one end near the lens of the imaging device and a cover connected thereto, and further comprising a lens cover for covering the lens of the imaging device, wherein a sliding rod is fixedly connected to the side of the lens cover away from the lens, and the sliding rod and the lens cover can be retracted into the housing.

[0008] By adopting the above technical solution, the lens of the imaging device is protected by an extendable lens cover inside the housing. When not in use, the lens cover can be stored in the box to avoid contamination, and at the same time, it can also prevent the lens cover from shaking and affecting the normal use of the imaging device. This achieves both protection of the imaging device lens and convenient storage of the imaging device lens cover.

[0009] The invention is further configured such that one end of the slide rod is rotatably connected to a slider, the slider is slidably connected to the housing, and a locking structure is provided between the end of the slide rod away from its own axis of rotation and the imaging device.

[0010] Preferably, the locking structure at the end of the slide bar is used to lock the lens cap to the imaging device, ensuring that the lens cap can be stably installed on the lens of the imaging device.

[0011] The invention is further configured such that the lens cover is concentrically provided with an elastic ring piece, the center of the elastic ring piece is fixedly connected to a pressure platform, the pressure platform is provided with a suction cup facing the lens of the imaging device, the slide rod is provided with a through-hole at the position corresponding to the pressure platform, and is rotatably connected to a pressure rod, the end of the pressure rod is provided with a pressure rod plane and a pressure rod convex surface facing opposite directions, the pressure rod plane does not contact the pressure platform, but the pressure rod convex surface, after contacting the pressure platform, can push it toward the lens.

[0012] Preferably, a suction cup is used to further enhance the stability of the lens cap connection.

[0013] The invention is further configured such that a top plate is rotatably connected to the top of the slide rod, and the top plate can be locked to a locking platform fixedly connected to the imaging device.

[0014] Preferably, the top plate and the locking platform can be interlocked.

[0015] The invention is further configured such that the top wall of the box body is provided with a groove for guiding the slider, and the groove can also prevent the suction cup from adhering to the inner wall of the box body.

[0016] Preferably, the groove can be either concave or convex, which can prevent the suction cup from adhering to the inner wall of the box while also guiding the slider.

[0017] The present invention is further configured such that the inner wall of the slide rod is provided with a limiting structure for restricting the rotation of the pressure rod, and the slide rod is provided with an arc-shaped notch at the end of the pressure rod away from its own axis of rotation.

[0018] Preferably, the pressure rod can be prevented from shaking after it has been rotated into place.

[0019] The invention is further configured such that a tension spring is provided between the slider and the inner wall of the box, the slider and the lens cover can be fully inserted into the box, and the box cover can be closed.

[0020] Preferably, the lens cap is sealed in a box to prevent it from becoming contaminated.

[0021] The invention is further configured such that a spring piece is fixedly connected to the end of the slide rod, and when the top plate cooperates with the locking platform, the spring piece contacts the same side of the top plate away from the locking platform.

[0022] Preferably, the spring can reset the top plate to a state where the locking platform is engaged with the top plate.

[0023] An imaging device includes a camera with a lens mounted on it and a housing fixedly connected to the bottom end of the lens, and a camera with a housing fixedly connected to the bottom end of the camera as well.

[0024] Preferably, the width and length of the housing are both greater than the diameter of the lens, so that the lens cap assembly can be installed in various imaging devices near their own lenses.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] 1. This invention installs a housing at the lens of an imaging device, using an extendable lens cap inside the housing to protect the lens of the imaging device. When not in use, the lens cap can be stored in the housing to avoid contamination, and it can also prevent the lens cap from shaking and affecting the normal use of the imaging device. This achieves convenient storage of the lens cap of the imaging device while protecting the lens.

[0027] 2. This invention fixes a sliding rod that can slide inside the box to the lens cover, and sets a suction cup structure in the center of the lens cover facing the lens. The pressure rod connected to the sliding rod pushes the suction cup to move towards the lens and thus adsorbs onto the lens, improving the stability of the connection between the lens cover and the lens of the imaging device. At the same time, since the lens cover and the central top plate are connected by an elastic ring, some air can be discharged between the lens cover and the lens of the imaging device during the adsorption of the lens by the suction cup, so that the lens cover and the lens of the imaging device are in a negative pressure state, which improves the connection stability of the lens cover and effectively improves the sealing performance of the lens cover.

[0028] 3. The present invention achieves a more stable fixation of the slide rod by rotating and connecting the top plate at the top of the slide rod, and by utilizing the cooperation between the flange of the top plate and the locking platform fixedly connected to the imaging device. Since the slide rod is fixedly connected to the lens cover, the stability of the lens cover after installation can be further improved.

[0029] 4. This invention provides a tension spring between the inner wall of the box and the slider. After the slider is pulled out of the box and rotated, the tension spring applies a force to the bottom of the slider in the direction of the imaging device lens through the slider. Combined with the locking structure at the top of the slider, this further ensures the stability of the lens cover. At the same time, the tension spring also makes it easier for the lens cover and the slider to retract into the box. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] The embodiments of the present invention will now be described.

[0048] First embodiment:

[0049] A lens cover assembly for an imaging device, see [link to documentation]. Figure 1-14 The system includes a housing 1, specifically, the housing 1 has a rectangular structure. The middle part of the housing 1 protrudes downward along its length to accommodate a sliding rod 3. The side length of the sliding rod 3 is greater than the diameter of the lens cap 4. The housing 1 is used to accommodate and protect the lens cap 4. The housing 1 is fixedly connected to the imaging device, and an opening is provided at the end near the lens of the imaging device, where a cover 8 is connected. Specifically, the housing 1 is fixedly connected to the end of the imaging device near its own lens 9. The cover 8 is rotatably connected to the end of the housing 1 with the opening. The cover 8 uses the friction between the closed state and the housing 1 to maintain a stable closure, so that the lens cap 4 can be stored in the housing 1 and avoid contamination. The system also includes a lens cap 4 for covering the lens of the imaging device. A sliding rod 3 is fixedly connected to the side of the lens cap 4 away from the lens. The sliding rod 3 and the lens cap 4 can be stored in the housing 1. After the lens cap 4 and the sliding rod 3 are stored in the housing 1, the lens cap 4 can be effectively prevented from shaking during the use of the imaging device.

[0050] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-6 One end of the slide rod 3 is rotatably connected to the slider 2, which is slidably connected inside the box 1. Specifically, the end of the box 1 is provided with a limiting structure at the opening to prevent the slider 2 from sliding out. In this embodiment, the limiting structure is a limiting strip fixedly connected to the inner wall of the box 1 to prevent the slider 2 from sliding out of the box 1. The end of the slide rod 3 away from its own axis of rotation is provided with a locking structure between it and the imaging device. Specifically, the locking structure can adopt various methods such as mechanical locking and electromagnetic locking. In this embodiment, mechanical locking is specifically adopted.

[0051] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-6 The locking structure at the end of the slide bar 3 locks with the imaging device, ensuring that the lens cap 4 can be stably installed on the lens of the imaging device. The top of the slide bar 3 is rotatably connected to the top plate 5, which can lock with the locking platform 6 fixedly connected to the imaging device. The top plate 5 and the locking platform 6 can be interlocked. Specifically, the bottom edge of the top plate 5 is provided with a downward protrusion, while the top edge of the locking platform 6 is provided with an upward protrusion. After the protrusions between the locking platform 6 and the top plate 5 are interlocked, they can restrict the horizontal movement of the top plate 5.

[0052] An imaging device, please refer to Figure 1-14 The camera 10 is equipped with a lens 9. Specifically, the lens 9 is detachably connected to the camera 10. The bottom of the lens 9 is fixedly connected to a housing 1. In other undisclosed embodiments, the housing 1 can also be fixedly connected to the side or top of the lens 9 without affecting the normal use of the camera 10.

[0053] It also includes a camera 11, inside which a lens 9 is installed. The end of the lens 9 installed inside the camera 11 extends out of the housing of the camera 11. The bottom of the camera 11 is also fixedly connected to a housing 1. Similarly, the housing 1 can be installed on other imaging devices not disclosed in this embodiment, and the lens cover 4 inside the housing 1 can be used to protect the glass surface of the lens 9. The width and length of the housing 1 are both greater than the diameter of the lens 9. The lens cover assembly can be installed on various imaging devices near the lens 9.

[0054] Second embodiment:

[0055] A lens cover assembly for an imaging device, see [link to documentation]. Figure 1-14Based on the first embodiment, the difference lies in that the lens cover 4 is concentrically provided with an elastic ring 401, and a pressure platform 402 is fixedly connected to the center of the elastic ring 401. Specifically, the elastic ring 401 is made of rubber, and can deform after being pressed by the pressure platform 402. A suction cup 403 is provided on the pressure platform 402 facing the lens of the imaging device. The slide rod 3 is provided with a through-hole 301 at the position corresponding to the pressure platform 402, and is rotatably connected to the pressure rod 7. Specifically, the through-hole 301 of the slide rod 3 is used for the pressure rod convex surface 702 of the pressure rod 7 to pass through, in order to avoid the pressure rod convex surface 702 from interacting with the slide rod 3. Interference occurs when the area of ​​the opening 301 is larger than the area of ​​the pressure rod convex surface 702 projected toward the opening 301. The end of the pressure rod 7 is provided with a pressure rod plane 701 and a pressure rod convex surface 702 facing opposite directions. The pressure rod plane 701 does not contact the pressure table 402, while the pressure rod convex surface 702 can push the pressure table 402 toward the lens after contacting it. Specifically, after the pressure rod 7 rotates 180 degrees, the pressure rod convex surface 702 of the pressure rod 7 can face the pressure table 402. At this time, the pressure table 402 is pushed toward the glass surface of the lens 9 by the pressure rod convex surface 702. The suction cup 403 is used to further improve the stability of the lens cover 4 connection.

[0056] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-6 The inner wall of the slide rod 3 is provided with a limiting structure for restricting the rotation of the pressure rod 7. In this embodiment, the inner wall of the slide rod 3 is specifically fixedly connected to a limiting block 302. When the pressure rod 7 contacts the limiting block 302, and when the torque of the pressure rod 7 is sufficient, the side wall of the slide rod 3 can deform, thereby allowing the pressure rod 7 to pass smoothly. The pressure rod 7 cannot pass the limiting block 302 by its own shaking. The slide rod 3 is provided with an arc-shaped notch at the end of the pressure rod 7 away from its own axis of rotation. Specifically, arc-shaped notches are provided at both ends of the side wall of the slide rod 3. When the pressure rod 7 faces the pressure table 402 with the pressure rod plane 701 or the pressure table 402 with the pressure rod 702, the position of the suction cup 403 corresponding to the end of the pressure rod 7 away from its own axis of rotation is provided with an arc-shaped notch so that the user can easily rotate the pressure rod 7. The setting of the limiting block 302 on the inner wall of the slide rod 3 can prevent the pressure rod 7 from shaking after it has rotated to the correct position.

[0057] For details regarding the above embodiments, please refer to [link / reference]. Figure 12-14 A spring piece 303 is fixedly connected to the end of the slide bar 3. When the top plate 5 and the locking platform 6 are engaged, the spring piece 303 and the top plate 5 are in contact on the same side away from the locking platform 6. Specifically, when the spring piece 303 is pressed down at the end of the top plate 5, it is in a state of accumulating elastic potential energy. After releasing, it can make the top plate 5 quickly return to its original position, so as to facilitate the quick engagement of the top plate 5 and the locking platform 6. In this embodiment, the spring piece 303 can make the top plate 5 return to the state where the locking platform 6 is engaged with each other.

[0058] Third embodiment:

[0059] A lens cover assembly for an imaging device, see [link to documentation]. Figure 1-14 Based on the first embodiment, the difference is that the top wall of the box 1 is provided with a groove 101 for guiding the slider 2. Under the guidance of the groove 101, the slider 2 can slide stably inside the box 1. The groove 101 can also prevent the suction cup 403 from adhering to the inner wall of the box 1. Specifically, after the slider 3 is rotated, the side of the lens cover 4 with the suction cup 403 faces upward. When the suction cup 403 slides towards the inside of the box 1, the groove 101 on the top surface of the inner wall of the box 1 prevents the top surface of the inner wall of the box from being flat, thus effectively preventing the suction cup 403 from adhering to the inner wall of the box 1 during the process of the lens cover 4 being put into the box 1. The groove 101 can be a concave groove or a convex groove. Specifically, in this embodiment, the groove 101 adopts a structure of two convex grooves. The groove 101 can prevent the suction cup 403 from adhering to the inner wall of the box 1 while also guiding the slider 2.

[0060] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-6 A tension spring is provided between the slider 2 and the inner wall of the box 1. As the slider 2 slides toward the opening of the box 1, the tension spring between the inner wall of the box 1 and the slider 2 is stretched and accumulates elastic potential energy. When the lens cap 4 is placed on the lens 9, the elastic force of the spring inside the box 1 can be applied to the bottom of the slide rod 3, applying a force parallel to the axis of the lens 9 and toward the lens 9 to the slide rod 3, further improving the stability of the lens cap 4 when it is fixed. The slide rod 3 and the lens cap 4 can be completely inserted into the box 1, and the box cover 8 can be closed. Specifically, the box cover 8 uses the friction with the edge of the box 1 to stably maintain the closed state, and the box 1 is used to seal and store the lens cap 4, preventing the lens cap 4 from being contaminated.

[0061] In practical use, the lens cover assembly of the imaging device works as follows: After opening the cover 8, pull out the slide rod 3. When the pivot of the slide rod 3 leaves the housing 1, rotate the slide rod 3 to close the lens cover 4 towards the lens 9. The inner wall of the lens cover 4 contacts the edge of the lens 9, and the friction between the lens cover 4 and the lens 9 achieves initial fixation of the lens cover 4. The edge of the top plate 5 at the top of the slide rod 3 lifts up after contacting the locking platform 6. The other end of the edge of the top plate 5 presses down on the spring 303, causing the spring 303 to undergo elastic deformation. Then, when the edge of the top plate 5 engages with the locking platform 6, the elastic force of the spring 303 causes the top plate 5 to return to its original position and complete the locking. The fixed platforms 6 are interlocked, and then the pressure rod 7 is rotated so that the pressure rod convex surface 702 at the end of the pressure rod 7 contacts the pressure platform 402, pushing the suction cup 403 toward the glass surface of the lens 9, so that the suction cup 403 is adsorbed on the glass surface of the lens 9. At the same time, due to the movement of the pressure platform 402, the elastic ring 401 is deformed, expelling some of the air between the lens cap 4 and the lens 9, so that the lens cap 4 and the lens 9 are in a negative pressure state. The air pressure presses the lens cap 4 in front of the lens 9, and the edge part of the lens cap 4 and the lens 9 that come into contact with each other forms an effective airtight area, thereby effectively reducing the amount of dust entering the front of the glass surface of the lens 9 and contaminating the lens.

[0062] When the imaging device needs to be used, first rotate the pressure rod 7 to reset it so that the pressure rod plane 701 of the pressure rod 7 faces the pressure table 402. Then press down the end of the top plate 5 away from the locking table 6 so that the top plate 5 is raised and separated from the locking table 6. Then rotate the slide rod 3 by the pivot of the slide rod 3 to separate the lens cover 4 from the lens 9. At the same time, the suction cup 403 is pulled out. After rotating the slide rod 3 to make it parallel to the slider 2, push the slide rod 3 and the lens cover 4 into the box 1 at the same time. Finally, close the box cover 8 to use the imaging device conveniently and avoid contamination of the lens cover 4.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
