Description

Technical Field

[0001] The invention relates to a camera device. Background Art

[0002] The outer shell of the existing spherical camera is easily covered with ice, which will affect the camera's field of view and pan / tilt rotation.

[0003] The current anti-icing measures for cameras usually use resistance wire heating. The resistance wire is generally selected between 6 ohms and 12 ohms at a 12V DC voltage, and the working current is generally between 1-2A. Using resistance wire heating can solve the problem of condensation and ice formation under low temperature conditions inside the camera. However, when the camera device relies on solar power to work, the equipment consumes electricity in mA or even uA, and it is impossible to consume a large amount of electricity in this anti-icing mode. Moreover, this anti-icing device cannot solve the problem of ice on the outside of the camera shield. Ice on the outer shell makes it impossible for the camera to take clearer photos.

[0013] The bottom edge of the arc-shaped cover body extends along the longitudinal direction.

[0014] In one embodiment, the top edge of the arc-shaped cover body extends in a horizontal direction.

[0015] In one embodiment, the anti-icing cover includes a hydrophobic layer formed on an outer surface of the arc-shaped cover body.

[0016] In one embodiment, the inner surface of the arc-shaped cover body forms a first guide column protruding along the longitudinal direction;

[0017] The top surface of the base forms a second guide column protruding in the longitudinal direction, the first guide column and the second guide column are connected together by a fastener, and the butt joint surfaces of the first guide column and the second guide column are spaced apart by an elastic element with elastic deformation in the longitudinal direction.

[0018] In one embodiment, the sunshade has an operating hole extending from the bottom surface thereof and communicating with the second guide column, and the fastener is movable in the operating hole along the longitudinal direction;

[0019] The operating hole has a matching surface for limiting the fastener in the longitudinal direction, and the fastener is fixedly connected to the first guide column.

[0020] In one embodiment, when the fastener is located at the mating surface, the distance between the mating surfaces of the first guide column and the second guide column is less than or equal to the free length of the elastic element and greater than the fully compressed length of the elastic element.

[0021] In one embodiment, the vibration assembly comprises:

[0022] A motor, wherein the motor has an output shaft that rotates in a horizontal direction, and the motor is fixedly connected to the inner wall of the arc-shaped cover;

[0023] A counterweight block is eccentrically mounted on the output shaft to generate a centrifugal force for compressing the elastic element in a longitudinal direction under the drive of the output shaft, so as to drive the anti-icing cover to vibrate relative to the sunshade with the preset amplitude.

[0024] In one embodiment, the motor is fixedly connected to the arc-shaped cover via a transfer sheet metal, and the transfer sheet metal includes:

[0025] a first supporting wall, wherein the first supporting wall is fixedly connected to the arc-shaped cover body and extends in a horizontal direction; and

The function of the anti-icing shield 20 is to protect from the source of ice formation, and to prevent ice from forming on the surface of the housing 11 of the camera assembly 10 by preventing the accumulation of water.

[0032] Furthermore, even if an anti-icing cover 20 with a function of preventing water accumulation is provided, the surface of the housing 11 may still be covered with ice due to the formation of a small amount of condensed water droplets due to condensation, etc. In order to ensure the effect of preventing ice, the camera device of this embodiment further provides a vibration component 30 in the closed cavity for loading a vibration driving force on the anti-icing cover, which drives the anti-icing cover 20 to vibrate with a preset amplitude to force the housing 11 (the connection point with the anti-icing cover) and the anti-icing cover 20 to separate from the ice on the surface, thereby achieving the effect of non-contact ice removal. The vibration component 30 can start to drive the anti-icing cover 20 to vibrate in response to a remotely sent de-icing instruction, without the need for staff to manually remove ice on site. The staff can judge whether there is ice on the surface that hinders shooting by observing the shooting picture of the camera assembly 10, and then send a de-icing instruction remotely.

[0050] In order to solve the problems in the prior art, the present invention provides a camera device including an anti-icing cover, which is installed on the outside of the shell of the camera component and can form a water-guiding surface above the spherical camera. In combination with a vibration component that removes ice by vibration, the anti-icing cover can prevent the formation of ice from the source, and can actively remove ice remotely when ice is generated.

[0051] Figure 1a and Figure 1b Schematic diagram and exploded diagram of the camera device of the present invention. Figure 1a and Figure 1b As shown, an embodiment of the present invention provides a camera device, comprising:

[0052] The camera assembly 10 includes a housing 11 and a spherical camera 12 disposed at the bottom of the housing 11. The housing 11 has a sunshade 13 extending outward from the bottom edge of the housing 11 to shield the spherical camera 12.

[0053] An anti-icing cover 20, which is coaxially sleeved on the housing 11 and has its bottom connected to the sunshade 13. The anti-icing cover 20, the housing 11 and the sunshade 13 enclose a closed cavity. The outer diameter of the anti-icing cover 20 is larger than the outer diameter of the spherical camera 12, so as to form a water guide surface with a diameter larger than that of the spherical camera 12 above the spherical camera 12; and

[0054] The vibration assembly 30 is installed in the closed cavity, and in response to the de-icing instruction, it loads a vibration driving force of a preset amplitude to the anti-icing cover 20, so that the anti-icing cover 20 vibrates relative to the sunshade cover 13 with the preset amplitude.

[0055] In this embodiment, an anti-icing shield 20 with good water-conducting function is provided on the surface of the camera assembly 10, which is used to timely guide the water condensed on the outer surface of the arc-shaped cover body 22 to avoid staying on the surface of the arc-shaped cover body 22 for too long, thereby avoiding the local temperature drop of the arc-shaped cover body 22 and the formation of ice. The function of the anti-icing shield 20 is to protect from the source of ice formation, and to prevent ice from forming on the surface of the housing 11 of the camera assembly 10 by preventing the accumulation of water.

[0056] Furthermore, even if an anti-icing cover 20 with a function of preventing water accumulation is provided, the surface of the housing 11 may still be covered with ice due to the formation of a small amount of condensed water droplets due to condensation, etc. In order to ensure the effect of preventing ice, the camera device of this embodiment further provides a vibration component 30 in the closed cavity for loading a vibration driving force on the anti-icing cover, which drives the anti-icing cover 20 to vibrate with a preset amplitude to force the housing 11 (the connection point with the anti-icing cover) and the anti-icing cover 20 to separate from the ice on the surface, thereby achieving the effect of non-contact ice removal. The vibration component 30 can start to drive the anti-icing cover 20 to vibrate in response to a remotely sent de-icing instruction, without the need for staff to manually remove ice on site. The staff can judge whether there is ice on the surface that hinders shooting by observing the shooting picture of the camera assembly 10, and then send a de-icing instruction remotely. This can not only save a lot of manpower and material resources for equipment maintenance, but also the vibration component 30 starts to operate in response to the de-icing instruction, rather than requiring long-term continuous work, which can save a lot of electric energy and avoid affecting the normal operation of the camera assembly.

[0057] Specifically, the anti-icing shield 20 is disposed at the bottom edge of the housing 11, docked with the sunshade 13 at the bottom of the housing 11, and can form an integrated shape with the sunshade 13, and can provide shielding for the spherical camera 12 below it from direct sunlight, moisture, falling rocks, etc. The housing 11 can be supported on a carrier by the top cover 15 on its top, that is, the position of the housing 11 is fixed, and the function of the vibration assembly 30 in this embodiment is to drive the anti-icing shield 20 to vibrate relative to the sunshade 13, that is, the object that generates a small amplitude reciprocating movement in the longitudinal direction is the anti-icing shield 20, rather than the sunshade 13 or even the housing 11, so as to isolate the vibration source from the camera assembly and prevent the vibration used for deicing from affecting the normal shooting of the camera assembly 10.

[0058] Specifically, the anti-icing cover 20 includes:

[0059] A first via hole 21; and

[0060] An arc-shaped cover body 22, which extends downward from the periphery of the first through hole 21 along the longitudinal direction;

[0061] The normal slope of the outer surface of the arc-shaped cover body 22 decreases along the longitudinal direction, so as to form a water-guiding surface through the convex arc shape;

[0062] The bottom edge of the arc-shaped cover body 22 extends in the longitudinal direction, and the top edge of the arc-shaped cover body 22 extends in the horizontal direction. Preferably, the anti-icing cover 20 includes a hydrophobic layer formed on the outer surface of the arc-shaped cover body 22.

[0063] The anti-icing cover 20 in this embodiment includes an arcuate cover body 22 extending downward from the peripheral wall of the first through hole 21, wherein the arcuate cover body 22 extends downward, and the normal slope of its outer surface tends to decrease along the longitudinal direction, thereby forming an outwardly convex arc surface shape, thereby forming a water guide surface that is conducive to the falling of water, and further, the bottom edge of the arcuate cover body 22 extends along the longitudinal direction, and the water guided to the bottom edge of the arcuate cover body 22 directly falls under the action of gravity and leaves the outer surface of the arcuate cover body 22.

[0064] Among them, the outer surface of the arc-shaped cover body 22 refers to its upper surface, that is, it can be connected with the shell 11 to form a waterproof and dustproof side surface for the spherical camera 12, and its inner surface refers to its lower surface facing the spherical camera 12.

[0065] The arc-shaped cover body 22 forms an outwardly convex arc-shaped surface, so the diameter of its bottom edge is larger than the diameter of the first through hole 21, and larger than the diameter of the spherical camera 12, thereby forming a waterproof, dustproof, and sun-shading water-conducting surface on the spherical camera 12, which not only avoids the accumulation of moisture and prevents the local temperature of the arc-shaped cover body surface from being too low, but also increases the rain protection angle for the spherical camera 12 and improves adaptability.

[0066] Preferably, the top edge of the arc-shaped cover body 22 extends in the horizontal direction. That is, the arc-shaped cover body 22 forms an arc angle of 90°, which is particularly conducive to the local accumulation of moisture on the surface of the arc-shaped cover body 22.

[0067] In order to improve the anti-icing effect of the anti-icing cover, Figure 2 As shown, the anti-icing cover 20 includes a hydrophobic layer 23 formed on the outer surface of the arc-shaped cover body 22 .

[0068] The hydrophobic layer 23 can prevent moisture from adhering to the outer surface of the arc-shaped cover body 22. Further, the hydrophobic layer can be coated on the outer surface of the arc-shaped cover body 22 using the Salvinia coating technology, which can form a surface contact angle of up to 150°, which is more conducive to the loss of moisture on the surface, so as to prevent moisture from adhering to the outer surface of the arc-shaped cover body 22 by preventing aggregation.

[0069] Since the function of the vibration component 30 in this embodiment is to drive the anti-icing cover 20 to vibrate relative to the sun shield 13, that is, the object that generates a small reciprocating movement in the longitudinal direction is the anti-icing cover 20, therefore, in this embodiment, although the anti-icing cover 20 is connected to the sun shield 13, it is not fixedly connected, but elastically connected in the vibration direction (that is, the longitudinal direction) to obtain a space that can realize a small reciprocating movement.

[0070] Specifically, Figure 4 As shown, the inner surface of the arc-shaped cover body 22 forms a first guide column 221 protruding along the longitudinal direction;

[0071] The top surface of the sunshade 13 forms a second guide column 131 protruding in the longitudinal direction, the first guide column 221 and the second guide column 131 are connected together by a fastener 132, and the mating surfaces of the first guide column 221 and the second guide column 131 are separated by an elastic element 40 with elastic deformation in the longitudinal direction.

[0072] Among them, the fastener 132 is not used to limit the distance between the mating surfaces of the first guide column 221 and the second guide column 131 to a constant distance, but is used to limit the maximum distance between the mating surfaces of the first guide column 221 and the second guide column 131, that is, to prevent the anti-icing cover 20 from detaching from the sunshade cover 13 and exposing the closed cavity.

[0073] The minimum distance between the butt joint surfaces of the first guide column 221 and the second guide column 131 is determined by the fully compressed length of the elastic element 40, i.e., the minimum length to which the elastic element 40 can be compressed in the longitudinal direction. The maximum distance between the butt joint surfaces of the first guide column 221 and the second guide column 131 is determined by the smaller of the free length of the elastic element 40 (i.e., the length without deformation when not subject to external force) and the length defined by the fastener 132. Normally, when the fastener 132 is fixed in place, the elastic element 40 is elastically deformed, i.e., it is squeezed by the first guide column 221 and the second guide column 131.

[0074] Specifically, the sunshade 13 has an operating hole 133 that penetrates from its bottom surface and the second guide column 131, and the fastener 132 is movable in the operating hole 133 along the longitudinal direction;

[0075] The operating hole 133 has a matching surface 1331 in the longitudinal direction for limiting the fastener 132 , and the fastener 132 is fixedly connected to the first guide column 221 .

[0076] Among them, the mating surface 1331 is located on the side of the operating hole 133 facing the bottom surface of the sunshade 13, and it is limited by the screw head of the fastener 132 to limit the movement of the fastener 132 toward the first guide column 221. The movement of the fastener 132 in the direction of one side toward the bottom surface of the sunshade 13 is not limited, but is limited by the elastic element 40.

[0077] It can be seen that the fastener 132 is fixedly connected to the first guide column 221, for example, by a thread, and is movably connected to the second guide column 131 with a limited range, so as to achieve a variable distance between the anti-icing cover 20 and the sunshade cover 13, so that when driven by the vibration assembly 30, the anti-icing cover 20 can be driven to vibrate to achieve the de-icing function, and can be isolated from the sunshade cover 13 and even the camera assembly 10 as a whole to avoid affecting the normal shooting of the camera assembly.

[0078] Specifically, when the fastener 132 is limited to the mating surface 1331, the distance between the first guide column 221 and the second guide column 131 is less than or equal to the free length of the elastic element 40 and greater than the fully compressed length of the elastic element 40. The preset amplitude corresponds to the compressed length of the elastic element 40.

[0079] Combination Figure 4 and Figure 7 As shown, the vibration assembly 30 includes:

[0080] A motor 31, wherein the motor 31 has an output shaft 31a that rotates in a horizontal direction, and the motor 31 is fixedly connected to the inner wall of the arc-shaped cover body 22;

[0081] The counterweight block 32 is eccentrically mounted on the output shaft 31a, so as to generate a centrifugal force to compress the elastic element 40 in the longitudinal direction driven by the output shaft 31a, so as to drive the anti-icing cover 20 to vibrate relative to the sunshade cover 13 with a preset amplitude.

[0082] like Figure 6b As shown, the counterweight 32 is eccentrically mounted on the output shaft 31a. Then, driven by the output shaft 31a, the counterweight generates a force in the direction of gravity of the counterweight, which is a reaction force to the centripetal force, i.e., centrifugal force. The force compresses the elastic element 40, thereby driving the anti-icing cover 20 to vibrate relative to the sunshade cover 13 with a preset amplitude.

[0083] The motor 31 is fixedly connected to the inner wall of the arc-shaped cover 22 , and the vibration source is isolated from the housing 11 as a whole.

[0084] Specifically, the force compresses the elastic element 40, and the distance between the mating surfaces of the first guide column 221 and the second guide column 131 is compressed to the fully compressed length of the elastic element 40 at a minimum. When the force is in the direction and the elastic element 40 rebounds, the distance between the mating surfaces of the first guide column 221 and the second guide column 131 is limited to the corresponding length limited by the mating surface 1331 at a maximum.

[0085] like Figure 7 As shown, the motor 31 is fixedly connected to the arc-shaped cover 22 via the adapter sheet metal 50, and the adapter sheet metal 50 includes:

[0086] A first support wall 51, the first support wall 51 is fixedly connected to the arc-shaped cover body 22, and the first support wall 51 extends in a horizontal direction; and

[0087] A second supporting wall 52, the second supporting wall 52 is connected to an end of the first supporting wall 51 and extends in the longitudinal direction, and the motor 31 is fixedly connected to the second supporting wall 52 to be disposed in a space enclosed by the first supporting wall 51 and the second supporting wall 52;

[0088] The output shaft 31 a passes through the second support wall 52 , and the motor 31 and the counterweight 32 are respectively located on two sides of the second support wall 52 .

[0089] like Figure 5 As shown, the vibration assembly 30 includes:

[0090] A control panel 33, the control panel 33 is installed in the housing 11;

[0091] The housing 11 has a through hole 14 communicating with the closed cavity, and a cable connected between the control board 33 and the motor 31 passes through the through hole 14 .

[0092] The vibration assembly 30 may include a plurality of motors 31 symmetrically distributed in the closed cavity, for example, arranged in pairs, such as one pair or two pairs. Figure 5 , two pairs of motors 31 are arranged, with adjacent motors arranged at equal angles, and cables 331 corresponding to the motors 31 one by one are arranged near the end corners of the control board 33 .

[0093] like Figure 8a and Figure 8b As shown, a glue potting sleeve 311 is added to the tail of the motor 31, and glue is poured through the glue potting groove 312 to achieve the purpose of waterproofing the cable.

[0094] In this embodiment, an anti-icing shield 20 with good water-conducting function is provided on the surface of the camera assembly 10, which is used to timely guide the water condensed on the outer surface of the arc-shaped cover body 22 to avoid staying on the surface of the arc-shaped cover body 22 for too long, thereby avoiding the local temperature drop of the arc-shaped cover body 22 and the formation of ice. The function of the anti-icing shield 20 is to protect from the source of ice formation, and to prevent ice from forming on the surface of the housing 11 of the camera assembly 10 by preventing the accumulation of water.

[0095] Furthermore, even if an anti-icing cover 20 with a function of preventing water accumulation is provided, the surface of the housing 11 may still be covered with ice due to the formation of a small amount of condensed water droplets due to condensation, etc. In order to ensure the effect of preventing ice, the camera device of this embodiment further provides a vibration component 30 in the closed cavity for loading a vibration driving force on the anti-icing cover, which drives the anti-icing cover 20 to vibrate with a preset amplitude to force the housing 11 (the connection point with the anti-icing cover) and the anti-icing cover 20 to separate from the ice on the surface, thereby achieving the effect of non-contact ice removal. The vibration component 30 can start to drive the anti-icing cover 20 to vibrate in response to a remotely sent de-icing instruction, without the need for staff to manually remove ice on site. The staff can judge whether there is ice on the surface that hinders shooting by observing the shooting picture of the camera assembly 10, and then send a de-icing instruction remotely. This can not only save a lot of manpower and material resources for equipment maintenance, but also the vibration component 30 starts to operate in response to the de-icing instruction, rather than requiring long-term continuous work, which can save a lot of electric energy and avoid affecting the normal operation of the camera assembly.

[0096] Specifically, the anti-icing shield 20 is disposed at the bottom edge of the housing 11, docked with the sunshade 13 at the bottom of the housing 11, and can form an integrated shape with the sunshade 13, and can provide shielding for the spherical camera 12 below it from direct sunlight, moisture, falling rocks, etc. The housing 11 can be supported on a carrier by the top cover 15 on its top, that is, the position of the housing 11 is fixed, and the function of the vibration assembly 30 in this embodiment is to drive the anti-icing shield 20 to vibrate relative to the sunshade 13, that is, the object that generates a small amplitude reciprocating movement in the longitudinal direction is the anti-icing shield 20, rather than the sunshade 13 or even the housing 11, so as to isolate the vibration source from the camera assembly and prevent the vibration used for deicing from affecting the normal shooting of the camera assembly 10.

[0097] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention, and are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention, such as combination, division or repetition of features, should be included in the scope of protection of the present invention.
