[0002] The existing camera housing is easy to hang ice, which will affect the camera's field of view and the rotation of the holder.

[0003] The current camera anti-icing measures generally use resistance wire heating method, the resistance wire is generally selected between 6 ohms and 12 ohms at 12V DC voltage, and the working current is generally between 1-2A. Using resistance wire heating can solve the problem of condensation and icing under low temperature conditions in the camera, but when the camera device works in solar power mode, the device consumes mA or even uA of electric energy, and it is impossible to consume a large amount of electric energy in this anti-icing mode. Moreover, this anti-icing device cannot solve the icing problem outside the camera shield, and the icing on the shell makes the camera unable to take clear photos. SUMMARY

[0004] In order to solve the above technical problems, the present application provides a camera device, which is provided with an anti-icing cover capable of forming a water guide surface above the spherical camera on the outside of the shell of the camera assembly, and a vibration assembly for removing ice by vibration, so as to prevent the generation of ice from the source and actively remove the ice remotely in case of ice generation.

[0005] In one embodiment of the present application, a camera device is provided, comprising:

[0006] a camera assembly, the camera assembly comprising a shell and a spherical camera arranged at the bottom of the shell, the shell having a sunshade extending outward from the edge of the bottom of the shell to shield above the spherical camera;

[0009] In one embodiment, the anti-icing cover comprises:

[0010] a first via hole; and

[0011] an arc-shaped cover body extending downward along a longitudinal direction from a periphery of the first through hole;

[0012] wherein a normal line slope of an outer surface of the arc-shaped cover body decreases along the longitudinal direction to form a water guide surface by an outward convex arc surface shape;

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

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

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

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

[0017] a top surface of the base forms a second guide post protruding along the longitudinal direction, the first guide post and the second guide post are connected together by a fastener, and an abutting surface between the first guide post and the second guide post is spaced by an elastic element having an elastic deformation amount along the longitudinal direction.

[0018] In one embodiment, the sunshade cover has an operation hole passing through a bottom surface thereof and the second guide post, the fastener is movable along the longitudinal direction within the operation hole;

[0019] the operation hole has a matching surface limiting the fastener in the longitudinal direction, and the fastener is fixedly connected with the first guide post.

[0020] In one embodiment, when the fastener is limited by the matching surface, a spacing between the abutting surface of the first guide post and the second guide post is less than or equal to a free length of the elastic element and greater than a fully compressed length of the elastic element.

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

[0022] a motor having an output shaft rotating around a horizontal direction, the motor being fixedly connected to an inner wall of the arc-shaped cover body;

[0023] a counterweight eccentrically arranged on the output shaft to form a centrifugal force compressing the elastic element in the longitudinal direction under driving of the output shaft to drive the anti-icing cover to vibrate relative to the sunshade cover at the preset vibration amplitude.

[0024] In one embodiment, the motor is fixedly connected with the arc-shaped cover body via an adapter sheet metal, the adapter sheet metal comprising:

The ice-preventing cover 20 functions to prevent ice from being formed on the surface of the shell 11 of the camera assembly 10 by preventing water from being accumulated.

[0032] Further, even if the ice-preventing cover 20 with the water accumulation preventing function is arranged, the surface of the shell 11 can still form a small amount of condensed water droplets and cause ice to be formed due to condensation and the like. In order to ensure the ice-preventing effect, the camera device of the embodiment further arranges a vibration assembly 30 for loading vibration driving force to the ice-preventing cover in the closed cavity, which drives the ice-preventing cover 20 to vibrate at a preset amplitude, so as to force the shell 11 (the joint part with the ice-preventing cover) and the ice-preventing cover 20 to separate from the ice on the surface, thereby achieving the effect of non-contact ice removal. The vibration assembly 30 can start to drive the ice-preventing cover 20 to vibrate in response to a remote ice-removing instruction, without the need of staff to manually remove ice on site, so that the staff can judge whether the ice on the surface of the camera assembly 10 hinders shooting by observing the shooting picture of the camera assembly 10, and then remotely send the ice-removing instruction.

Unless otherwise stated, the numerical ranges in the present document include not only the entire range between the two endpoints, but also several sub-ranges contained therein.

[0049] Now, example embodiments will be described more fully with reference to the accompanying drawings.

[0050] In order to solve the problems in the prior art, the present application provides a camera device comprising an anti-icing cover, which is installed outside the shell of the camera assembly and can form a water guide surface above the spherical camera, and combines a vibration assembly for removing ice by vibration, so as to prevent the generation of ice from the source and actively remove the ice remotely in the case of ice generation.

[0051] Figure 1a And Figure 1b are a structural schematic diagram and an exploded schematic diagram of the camera device of the present application. As shown in Figure 1a And Figure 1b An embodiment of the present application provides a camera device, comprising:

[0052] A camera assembly 10, which comprises a shell 11 and a spherical camera 12 arranged at the bottom of the shell 11, and the shell 11 has a sunshade 13 extending outward from the edge of the bottom of the shell 11 to shield above the spherical camera 12;

[0053] An ice shield 20 is coaxially sleeved on the shell 11 and abuts against the sunshade 13, the ice shield 20, the shell 11 and the sunshade 13 form a closed cavity, the outer diameter of the ice shield 20 is larger than the outer diameter of the spherical camera 12, so as to form a water guide surface above the spherical camera 12 with a diameter larger than that of the spherical camera 12; and

[0054] A vibration assembly 30 is arranged in the closed cavity, which loads a vibration driving force with a preset amplitude on the ice shield 20 in response to a deicing instruction, so that the ice shield 20 vibrates relative to the sunshade 13 with the preset amplitude.

[0055] The embodiment provides the ice shield 20 with good water guide function on the surface of the camera assembly 10, which can timely guide the water condensed on the outer surface of the arc-shaped cover 22 away, so as to avoid the water staying on the surface of the arc-shaped cover 22 for too long time, thereby avoiding the local temperature reduction of the arc-shaped cover 22 and the icing. The ice shield 20 functions to prevent the icing on the surface of the shell 11 by preventing the accumulation of water.

[0056] Further, even if the ice shield 20 with the water accumulation prevention function is arranged, the surface of the shell 11 can still form a small amount of condensed water droplets due to condensation and the like, and form icing. In order to ensure the effect of preventing icing, the camera device further arranges the vibration assembly 30 in the closed cavity, which loads a vibration driving force on the ice shield 20, drives the ice shield 20 to vibrate with a preset amplitude, and separates the icing on the surface from the shell 11 (abutting part of the ice shield) and the ice shield 20, so as to achieve the effect of non-contact deicing. The vibration assembly 30 can start to drive the ice shield 20 to vibrate in response to the deicing instruction sent remotely, without the need of manual deicing by the staff on site, so that the staff can judge whether the icing on the surface of the camera assembly 10 affects the shooting by observing the shooting picture, and then send the deicing instruction remotely. This not only can greatly save the manpower and material resources for equipment maintenance, but also the vibration assembly 30 starts to work in response to the deicing instruction, rather than needs to work continuously for a long time, so that the electric energy can be greatly saved, and the normal work of the camera assembly can be avoided.

[0057] Specifically, the anti-icing cover 20 is arranged at the bottom edge of the shell 11 and is in abutment with the sunshade 13 at the bottom of the shell 11, and can form an integrated appearance with the sunshade 13, and can provide the spherical camera 12 below with the functions of shielding sunlight, moisture, falling rocks and the like. The shell 11 can be supported on the carrier through the top cover 15 at the top of the shell 11, that is, the position of the shell 11 is fixed, and the function of the vibration assembly 30 in the embodiment is to drive the anti-icing cover 20 to vibrate relative to the sunshade 13, that is, the object of the small-amplitude reciprocating movement in the longitudinal direction is the anti-icing cover 20, rather than the sunshade 13 or even the shell 11, so as to separate the vibration source from the camera assembly, and avoid the influence of the vibration for deicing on the normal shooting of the camera assembly 10.

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

[0059] a first through hole 21; and

[0060] an arc-shaped cover body 22 extending downward from the peripheral wall of the first through hole 21 in the longitudinal direction;

[0061] wherein the normal slope of the outer surface of the arc-shaped cover body 22 decreases along the longitudinal direction to form a water guide surface through the convex arc surface 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 the embodiment includes the arc-shaped cover body 22 extending downward from the peripheral wall of the first through hole 21, wherein the arc-shaped cover body 22 extends downward, and the normal slope of the outer surface thereof has a decreasing trend along the longitudinal direction, thereby forming a convex arc surface shape, thereby forming a water guide surface conducive to the falling of moisture, and further, the bottom edge of the arc-shaped cover body 22 extends in the longitudinal direction, so that the moisture flowing to the bottom edge of the arc-shaped cover body 22 directly falls away from the outer surface of the arc-shaped cover body 22 under the action of gravity.

[0064] wherein the outer surface of the arc-shaped cover body 22 refers to the upper surface thereof, that is, the side surface capable of abutting with the shell 11 to form a waterproof and dustproof side surface for the spherical camera 12, and the inner surface thereof refers to the lower surface thereof toward the side of the spherical camera 12.

[0065] The arc-shaped cover body 22 forms a convex arc surface, so that the diameter of the bottom edge thereof is greater than the diameter of the first through hole 21 and greater than the diameter of the spherical camera 12, thereby forming a water guide surface for the spherical camera 12 to be waterproof, dustproof and sun-shielded, not only avoiding the accumulation of moisture and preventing the local temperature of the arc-shaped cover body surface from being too low, but also increasing the rainproof angle for the spherical camera 12 and improving the 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-shaped angle of 90°, which is particularly advantageous for the local accumulation of water on the surface of the arc-shaped cover body 22.

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

[0068] The hydrophobic layer 23 can prevent water 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 Salvinia bubble technology, which can form a surface contact angle of up to 150°, which is more advantageous for the dissipation of water on the surface, so as to prevent water from adhering to the outer surface of the arc-shaped cover body 22 by preventing accumulation.

[0069] Since the vibration assembly 30 in the present embodiment acts to drive the anti-icing cover 20 to vibrate relative to the sunshade 13, i.e., the object that generates small-amplitude reciprocating movement in the longitudinal direction is the anti-icing cover 20, in the present embodiment, the anti-icing cover 20 is not fixedly connected with the sunshade 13, but is elastically connected in the vibration direction (i.e., the longitudinal direction) to obtain a space capable of realizing small-amplitude reciprocating movement.

[0070] Specifically, as shown in Figure 4 The inner surface of the arc-shaped cover body 22 forms a first guide column 221 protruding in 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 through a fastener 132, and the abutting surfaces of the first guide column 221 and the second guide column 131 are spaced apart by an elastic element 40 having an elastic deformation amount in the longitudinal direction.

[0072] The fastener 132 is not used to limit the distance between the abutting 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 abutting surfaces of the first guide column 221 and the second guide column 131, i.e., to prevent the anti-icing cover 20 from being separated from the sunshade 13 to expose the closed cavity.

[0073] The minimum distance between the abutting surfaces of the first guide column 221 and the second guide column 131 is determined by the full compression length of the elastic element 40, i.e. the minimum length by which the elastic element 40 can be compressed in the longitudinal direction. The maximum distance between the abutting surfaces of the first guide column 221 and the second guide column 131 is determined by the smaller one of the free length of the elastic element 40, i.e. the length without deformation under external force, and the length defined by the fastener 132. Generally, the elastic element 40 is elastically deformed, i.e. is pressed by the first guide column 221 and the second guide column 131, when the fastener 132 is fixed in place.

[0074] Specifically, the sunshade 13 has an operation hole 133 through which the second guide column 131 penetrates from the bottom surface of the sunshade 13, and the fastener 132 is movable in the longitudinal direction within the operation hole 133;

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

[0076] The matching surface 1331 is located on the side of the operation hole 133 facing the bottom surface of the sunshade 13, and is in limiting cooperation with the screw head of the fastener 132 to limit the movement of the fastener 132 towards the first guide column 221, while the movement of the fastener 132 in the direction towards the bottom surface of the sunshade 13 is not limited, but is limited by the elastic element 40.

[0077] Therefore, the fastener 132 is fixedly connected with the first guide column 221, for example, by threads or the like, and is movably connected with the second guide column 131 within a limited range, so that the distance between the anti-icing cover 20 and the sunshade 13 is variable, so as to be able to drive the anti-icing cover 20 to vibrate to realize the deicing function under the driving of the vibration assembly 30, and to be isolated from the sunshade 13 and even the entire camera assembly 10, so as to avoid affecting the normal shooting of the camera assembly.

[0078] Specifically, when the fastener 132 is limited by the matching surface 1331, the distance between the abutting surfaces of 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 is greater than the full compression length of the elastic element 40. The preset amplitude corresponds to the compressed length of the elastic element 40.

[0079] In combination with FIGS. 1-3, Figure 4 and Figure 7 It is shown that the vibration assembly 30 comprises:

[0080] The motor 31 has an output shaft 31a rotating around the horizontal direction, and the motor 31 is fixedly connected to the inner wall of the arc-shaped cover body 22;

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

[0082] As shown in Figure 6b , the counterweight 32 is eccentrically arranged on the output shaft 31a, so that the counterweight will generate a force along the direction of gravity of the counterweight under the driving of the output shaft 31a. The force is the reaction force of the centripetal force, that is, the centrifugal force. The force compresses the elastic element 40, thereby driving the anti-icing cover 20 to vibrate relative to the sunshade cover 13 at a preset amplitude.

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

[0084] Specifically, the force compresses the elastic element 40, so that the spacing between the abutting surfaces of the first guide column 221 and the second guide column 131 is compressed to the full compression length of the elastic element 40, and when the elastic element 40 rebounds, the spacing between the abutting surfaces of the first guide column 221 and the second guide column 131 is limited to the corresponding length defined by the fitting surface 1331.

[0085] As shown in Figure 7 , the motor 31 is fixedly connected to the arc-shaped cover body 22 via the adapter panel 50, and the adapter panel 50 comprises:

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

[0087] a second support wall 52, the second support wall 52 being connected to the end of the first support wall 51 and extending in the longitudinal direction, and the motor 31 being fixedly connected to the second support wall 52 to be arranged in the space enclosed by the first support wall 51 and the second support wall 52;

[0088] The output shaft 31a penetrates 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] As shown in Figure 5 , the vibration assembly 30 comprises:

[0090] a control panel 33 arranged in the shell 11;

[0091] The shell 11 has a through hole 14 communicating with the closed cavity, and an electric cable connected between the control panel 33 and the motor 31 penetrates the through hole 14.

[0092] The vibration assembly 30 can include a plurality of motors 31, which are symmetrically distributed in the closed cavity, for example, in pairs, such as one pair or two pairs. Figure 5 The arrangement of the two pairs of motors 31 is shown in the middle, and the adjacent motors are arranged at equal angles, and the cables 331 corresponding to the motors 31 are arranged adjacent to the end corners of the control panel 33.

[0093] As shown in Figure 8a and Figure 8b The tail of the motor 31 is increased with a glue pouring sleeve 311, and the glue pouring groove 312 is poured with glue to achieve the purpose of waterproofing the cable.

[0094] The embodiment provides an ice-proof cover 20 with good water guide function on the surface of the camera assembly 10, which can timely guide the water condensed on the outer surface of the arc-shaped cover body 22 out, so as to avoid the water on the surface of the arc-shaped cover body 22 for too long time, thereby avoiding the local temperature reduction of the arc-shaped cover body 22 and the icing. The function of the ice-proof cover 20 is to prevent icing on the surface of the camera assembly 10 by preventing the accumulation of water.

[0095] Further, even if the ice-proof cover 20 with the water accumulation prevention function is provided, the surface of the shell 11 can still form a small amount of condensed water droplets due to condensation and other reasons, and in order to ensure the effect of preventing icing, the camera device of the embodiment further provides a vibration assembly 30 in the closed cavity for loading vibration driving force to the ice-proof cover, which drives the ice-proof cover 20 to vibrate at a predetermined amplitude, so as to separate the icing on the surface from the shell 11 (the joint part with the ice-proof cover) and the ice-proof cover 20, thereby achieving the effect of non-contact removal of the icing. The vibration assembly 30 can start to drive the ice-proof cover 20 to vibrate in response to the remote ice removal instruction, without the need for manual deicing by the staff on site, and the staff can determine whether there is icing on the surface of the camera assembly 10 by observing the shooting picture of the camera assembly 10, and then remotely send the ice removal instruction. This not only can greatly save the manpower and material resources for equipment maintenance, but also the vibration assembly 30 starts to work in response to the ice removal instruction, rather than needs long-time continuous work, which can greatly save the electric energy and avoid affecting the normal work of the camera assembly.

[0096] Specifically, the anti-icing cover 20 is arranged at the bottom edge of the shell 11 and is in abutment with the sunshade 13 at the bottom of the shell 11, and can form an integrated appearance with the sunshade 13, and can provide the spherical camera 12 below with the functions of shielding direct sunlight, moisture, falling rocks, etc. The shell 11 can be supported on the carrier through the top cover 15 at the top of the shell 11, that is, the position of the shell 11 is fixed, and the function of the vibration assembly 30 in the embodiment is to drive the anti-icing cover 20 to vibrate relative to the sunshade 13, that is, the object of the small-amplitude reciprocating movement in the longitudinal direction is the anti-icing cover 20, rather than the sunshade 13 or even the shell 11, so as to separate the vibration source from the camera assembly, and avoid the influence of the vibration for deicing on the normal shooting of the camera assembly 10.

Any equivalent embodiments or changes made without departing from the spirit of the present application, such as the combination, division or repetition of features, shall be included in the protection scope of the present application.
