Description

Technical Field

[0001] The invention relates to the field of imaging device lens covers, in particular to an imaging device and a lens cover assembly thereof. Background Art

[0002] The 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 groups of the lens when the lens is not in use to prevent damage to the lens from dust, moisture or accidental bumps.

[0003] The existing imaging device lens cover adopts a clamping block that expands and contracts in opposite directions along the diameter and cooperates with a spring. After the clamping blocks slide in opposite directions, the lens cover is aligned with the lens of the imaging device and then released. The clamping block is reset by the elastic force of the spring and clamps the edge of the lens of the imaging device, completing the installation of the lens cover. The same applies when you want to remove the lens cover.

[0004] A Chinese patent with the related announcement number CN206039114U discloses a lens cover assembly for an imaging device, including a lens cover body and a fixing member, which is arranged on the lens cover body and fixedly connected to the housing of the imaging device in a detachable manner.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0047] The following describes an embodiment of the present invention based on its overall structure.

[0048] First embodiment:

[0049] A lens cover assembly for an imaging device, see Figure 1-14 , including a box body 1. Specifically, the box body 1 is a rectangular structure. The middle part of the box body 1 protrudes downward along the length direction to provide a space for accommodating a sliding rod 3, and the side lengths of the space are all greater than the diameter of the lens cover 4 for accommodating and protecting the lens cover 4. The box body 1 is fixedly connected to the imaging device, and an end close to the lens of the imaging device is opened and connected with a box cover 8. Specifically, the box body 1 is fixedly connected to an end of the imaging device close to its own lens 9, and the box cover 8 is rotatably connected to the end of the box body 1 where the opening is provided. The box cover 8 maintains a stable closure by utilizing the friction between the closed state and the box body 1, so that the lens cover 4 can be prevented from being contaminated after being stored in the box body 1. It also includes a lens cover 4 for covering the lens of the imaging device, and a sliding rod 3 is fixedly connected to a side of the lens cover 4 away from the lens, and the sliding rod 3 and the lens cover 4 can be received in the box body 1. After the lens cover 4 and the sliding rod 3 are received in the box body 1, it is possible to effectively prevent the lens cover 4 from shaking during the use of the imaging device.

[0050] In the above embodiments, please refer to Figure 3-6 One end of the slide rod 3 is rotatably connected to the slide block 2, and the slide block 2 is slidably connected to the box body 1. Specifically, a limiting structure for preventing the slide block 2 from sliding out is provided at the opening position at the end of the box body 1. In the present embodiment, the limiting structure adopts a limiting strip fixedly connected to the inner wall of the box body 1 to prevent the slide block 2 from sliding out of the box body 1. A locking structure is provided between the end of the slide rod 3 away from its own rotating shaft and the imaging device. Specifically, the locking structure can adopt various methods such as mechanical locking and electromagnetic locking. In the present embodiment, a mechanical locking method is specifically adopted.

[0051] In the above embodiments, please refer to Figure 3-6 The locking structure at the end of the slide bar 3 is mutually locked with the imaging device to ensure that the lens cover 4 can be stably installed on the lens of the imaging device. The top end of the slide bar 3 is rotatably connected to a top plate 5, and the top plate 5 can be locked with a locking platform 6 fixedly connected to the imaging device. The top plate 5 and the locking platform 6 can be engaged with each other. Specifically, a downward convex strip is provided at the bottom end of the edge of the top plate 5, and an upward convex strip is provided at the top end of the edge of the locking platform 6. The convex strip between the locking platform 6 and the top plate 5 can limit the horizontal movement of the top plate 5 after being engaged with each other.

[0052] An imaging device, see Figure 1-14 , including a camera 10, on which a lens 9 is mounted. Specifically, the lens 9 and the camera 10 are detachably connected, and the bottom end of the lens 9 is fixedly connected with a box body 1. In other undisclosed embodiments, the box body 1 can also be fixedly connected to the side or top end of the lens 9 without affecting the normal use of the camera 10;

[0053] The camera 11 further includes a camera 11, wherein a lens 9 is installed inside the camera 11, and the end of the lens 9 installed inside the camera 11 extends out of the housing of the camera 11. The bottom end of the camera 11 is also fixedly connected to a box body 1. Similarly, the box body 1 can be installed on other imaging devices not disclosed in the present embodiment, and then the lens cover 4 in the box body 1 is used to protect the glass surface of the lens 9. The width and length of the box body 1 are both greater than the diameter of the lens 9, and the lens cover assembly can be installed at a position close to the lens 9 of a variety of imaging devices.

[0054] Second embodiment:

[0055] A lens cover assembly for an imaging device, see Figure 1-14On the basis of the first embodiment, the difference from the first embodiment is that the lens cover 4 is concentrically provided with an elastic ring piece 401, and the center of the elastic ring piece 401 is fixedly connected with a pressure platform 402. Specifically, the elastic ring piece 401 is made of rubber. After the pressure platform 402 is pressed, the elastic ring piece 401 can be deformed. The pressure platform 402 is provided with a suction cup 403 toward the lens of the imaging device. The slide bar 3 is provided with a through hole 301 at a position corresponding to the pressure platform 402, and is rotatably connected with the pressure rod 7. Specifically, the through hole 301 of the slide bar 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 bar 3, Interference with each other, the area of ​​the through hole 301 is larger than the area of ​​the projection of the pressure rod convex surface 702 toward the through hole 301, the end of the pressure rod 7 is provided with a pressure rod plane 701 and a pressure rod convex surface 702 facing oppositely, the pressure rod plane 701 does not contact the pressure platform 402, and the pressure rod convex surface 702 can push the pressure platform 402 toward the direction of the lens after contacting it. Specifically, after the pressure rod 7 rotates one hundred and eighty degrees, the pressure rod convex surface 702 of the pressure rod 7 can be directed toward the pressure platform 402. At this time, the pressure platform 402 is pushed by the pressure rod convex surface 702 to move toward the glass surface of the lens 9, and the suction cup 403 is used to further improve the stability of the connection of the lens cover 4.

[0056] In the above embodiments, please refer to Figure 3-6 The limit block 302 on the inner wall of the slide bar 3 is specifically fixedly connected to the limit block 302. When the slide bar 7 contacts the limit block 302 and the torque of the slide bar 7 is sufficient, the side wall of the slide bar 3 can be deformed, thereby allowing the slide bar 7 to pass smoothly. The slide bar 7 cannot pass the limit of the limit block 302 by its own shaking. Specifically, the slide bar 3 is provided with an arc notch at the end of the slide bar 3 away from its own rotation axis. Specifically, the two ends of the side wall of the slide bar 3 are provided with an arc notch. When the slide bar 7 faces the pressure platform 402 with the press rod plane 701 or the press rod 7 faces the pressure platform 402 with the press rod convex surface 702, the position of the suction cup 403 corresponding to the end of the slide bar 7 away from its own rotation axis is provided with an arc notch, so that the user can easily rotate the slide bar 7. The setting of the limit block 302 on the inner wall of the slide bar 3 can prevent the slide bar 7 from shaking after the slide bar 7 is rotated into place.

[0057] In the above embodiments, please refer to Figure 12-14 The end of the slide rod 3 is fixedly connected with a spring piece 303. When the top plate 5 cooperates with the locking platform 6, the spring piece 303 contacts the same side of the top plate 5 away from the locking platform 6. Specifically, the spring piece 303 is in a state of accumulating elastic potential energy when the end of the top plate 5 is pressed down. After releasing the hand, the top plate 5 can be quickly reset to facilitate the rapid cooperation between the top plate 5 and the locking platform 6. In this embodiment, the spring piece 303 can reset the top plate 5 to a state where the locking platform 6 is mutually engaged.

[0058] The third embodiment:

[0059] A lens cover assembly for an imaging device, see Figure 1-14 , based on the first embodiment, the difference from the first embodiment is that the top wall in the box body 1 is provided with a slide groove 101 for guiding the slider 2. The slider 2 can stably slide in the box body 1 under the guidance of the slide groove 101, and the slide groove 101 can also prevent the suction cup 403 from adsorbing the inner wall of the box body 1. Specifically, after the slide rod 3 rotates, the lens cover 4 is provided with a side of the suction cup 403 facing upwards. When the suction cup 403 slides toward the inside of the box body 1, the top surface of the inner wall of the box body 1 is provided with the slide groove 101, so that the top surface of the inner wall of the box body is not a plane, thereby effectively preventing the suction cup 403 from adsorbing the inner wall of the box body 1 during the process of the lens cover 4 being received into the box body 1. The slide groove 101 can be a concave groove or a convex groove. Specifically, in this embodiment, the slide groove 101 adopts a structure of two convex grooves. The slide groove 101 can prevent the suction cup 403 from adsorbing the inner wall of the box body 1 and can also play a role in guiding the slider 2.

[0060] In the above embodiments, please refer to Figure 3-6 A tension spring is arranged between the slider 2 and the inner wall of the box body 1. When the slider 2 slides toward the opening direction of the box body 1, the tension spring between the inner wall of the box body 1 and the slider 2 is stretched and elastic potential energy is accumulated. When the lens cover 4 is covered on the lens 9, the elastic force of the spring in the box body 1 can be applied to the bottom end of the slide bar 3, and a force parallel to the axis of the lens 9 and toward the lens 9 is applied to the slide bar 3, thereby further improving the stability of the lens cover 4 when it is fixed. The slide bar 3 and the lens cover 4 can completely enter the box body 1, and the box cover 8 can be closed. Specifically, the box cover 8 uses the friction force with the edge of the box body 1 to stably maintain the covered state, and uses the box body 1 to seal and store the lens cover 4 to prevent the lens cover 4 from being contaminated.

[0061] When the lens cover assembly of the imaging device is used specifically: after opening the box cover 8, pull out the slide bar 3; when the rotating shaft of the slide bar 3 leaves the box body 1, rotate the slide bar 3 to make the lens cover 4 close in the direction of the lens 9; the inner wall of the lens cover 4 and the edge of the lens 9 contact each other; the friction between the lens cover 4 and the lens 9 is used to achieve the initial fixation of the lens cover 4; and the edge of the top plate 5 at the top of the slide bar 3 rises after contacting the locking platform 6; the other end of the edge of the top plate 5 presses down the spring piece 303 to make the spring piece 303 produce elastic deformation; and then when the edge of the top plate 5 cooperates with the locking platform 6, the elastic force of the spring piece 303 causes the top plate 5 to return to its original position and complete the lock. The fixed platforms 6 are mutually locked, and then the pressure rod 7 is rotated to make the pressure rod convex surface 702 at the end of the pressure rod 7 contact the pressure platform 402, and then the suction cup 403 is pushed 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 piece 401 is deformed, and part of the air between the lens cover 4 and the lens 9 is discharged, so that the lens cover 4 and the lens 9 are in a negative pressure state, and the air pressure presses the lens cover 4 in front of the lens 9. The edge portion where the lens cover 4 and the lens 9 contact each other forms an effective airtight area, thereby effectively reducing dust from entering the glass surface of the lens 9 and contaminating the lens;

[0062] When the imaging device needs to be used, the pressure rod 7 is first rotated to reset it so that the pressure rod plane 701 of the pressure rod 7 faces the pressure platform 402, and then the end of the top plate 5 away from the locking platform 6 is pressed down to make the top plate 5 tilted and separated from the locking platform 6, and then the sliding rod 3 is rotated by the rotating axis of the sliding rod 3 to separate the lens cover 4 and the lens 9 from each other. At the same time, the suction cup 403 is pulled apart, and after the sliding rod 3 is rotated to make it parallel to the slider 2, the sliding rod 3 and the lens cover 4 are pushed into the box body 1 at the same time, and finally the box cover 8 is closed to conveniently use the imaging device while preventing the lens cover 4 from being contaminated.
