Description

Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to a deicing device and a camera. Background Art

[0002] When the camera is in a low temperature environment such as winter, ice and snow may form on the outer surface of the window, which will affect the imaging effect of the camera.

[0003] In the related prior art, a heating plate or other structure is usually used to heat the window to melt ice. However, due to the influence of the power supply of the camera, there is a problem that the heating power of the heating plate is small, resulting in the ice on the outer surface of the window not being completely melted. Increasing the power supply of the camera will cause the size of the camera to become larger, and the cost will increase. Utility Model Content

[0004] Based on this, it is necessary to provide a deicing device and a camera to address the above problems. The deicing device can ensure the deicing effect and does not need to increase the power supply of the camera.

[0005] The utility model first provides a deicing device for deicing the window of a camera body, comprising: a shell, which is arranged outside the camera body and can reciprocate on the outer surface of the window; a heating element, which is arranged in the shell and can move together with the shell; and an ice blade assembly, which is arranged in the shell and can move together with the shell, and the ice blade assembly includes an ice blade body, and the ice blade body can rotate independently relative to the shell to break ice covering the outer surface of the window.

[0006] In the above-mentioned de-icing device, when the shell reciprocates on the outer surface of the window, the ice blade body and the heating element move together with the shell. The ice blade body can rotate independently relative to the shell to break the thicker ice covering the outer surface of the window. The heating element can heat the window and the ice covering the outer surface of the window to melt the thin ice covering the outer surface of the window, thereby ensuring that the ice on the outer surface of the window can be completely removed and the de-icing effect is guaranteed, so that the camera can meet the use requirements of low temperature environments, expand the scope of application, and there is no need to increase the power supply of the camera, thereby avoiding increasing the overall volume of the camera.

[0007] In one embodiment, the ice blade assembly further comprises a support member, and when the support member is supported on the outer surface of the viewing window, a gap is formed between the ice blade body and the outer surface of the viewing window.

[0008] Such arrangement can prevent the skate body from contacting the outer surface of the window and scratching the window, thereby protecting the window.

[0009] In one of the embodiments, the support member is configured as a roller that can rotate relative to the housing.

[0010] With such an arrangement, the roller can reduce the friction between the support member and the window, thereby preventing the ice skate assembly and the housing from getting stuck when moving relative to the window, and also preventing the support member from scratching the window.

[0011] In one embodiment, the roller is coaxially arranged with the ice blade body, and the diameter of the roller is greater than the diameter of the ice blade body.

[0012] This arrangement ensures that the skate body will not contact the outer surface of the window when it is rotated to any angle.

[0013] In one embodiment, there are two support members, and the two support members are respectively disposed at two ends of the ice skate body.

[0014] Such an arrangement can improve the stability of the ice blade body, prevent the ice blade body from tilting and contacting the outer surface of the window, and also enable the ice blade body to evenly break the ice on the outer surface of the window.

[0015] In one embodiment, the shell is provided with a first mounting cavity, the opening of the first mounting cavity faces the viewing window, and a portion of the ice blade body is accommodated in the first mounting cavity; and / or, the ice blade assembly further includes a first driving member for driving the ice blade body to rotate relative to the shell.

[0016] With such arrangement, the shell can protect the ice blade body and improve the safety of the de-icing device.

[0017] In one of the embodiments, the deicing device further comprises a wiper disposed on the housing, wherein the wiper faces the window and is capable of contacting the window.

[0018] With this arrangement, the wipers can sweep away the melted ice and water on the outer surface of the window to prevent the melted ice and water from refreezing. At the same time, it also makes the images captured by the camera clearer, ensuring the imaging effect of the camera.

[0019] In one embodiment, the deicing device further includes a driving assembly, wherein the driving assembly includes a second driving member accommodated in the camera body, and the second driving member is used to drive the shell to reciprocate on the outer surface of the window.

[0020] With such arrangement, the second driving member is accommodated in the camera body, which can prevent the second driving member from being exposed and easily damaged.

[0021] In one embodiment, the drive assembly further includes a sleeve and an elastic member, wherein two ends of the sleeve are respectively connected to the second drive member and the shell, and the shell can rotate relative to the sleeve; two ends of the elastic member are respectively connected to the sleeve and the shell, and can press the shell toward the window.

[0022] With such a configuration, the elastic member enables the ice blade assembly to be pressed against the outer surface of the window or the ice on the outer surface of the window, and when the thickness of the ice covering the outer surface of the window gradually decreases, the ice blade assembly can also rotate relative to the sleeve closer to the window, thereby enhancing the ice-crushing effect of the ice blade assembly.

[0023] An embodiment of the utility model further provides a camera, comprising a camera body and the deicing device as described above, wherein the camera body has a viewing window.

[0024] With such a setting, the camera can meet the use requirements in low-temperature environments and expand its scope of application. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0036] When the camera is in a low temperature environment such as winter, ice and snow may form on the outer surface of the window, thus affecting the imaging effect of the camera. In the related prior art, a heating plate or other structure is usually used to heat the window to melt the ice. However, due to the influence of the power supply of the camera, there is a problem that the heating power of the heating plate is small, resulting in the problem that the ice on the outer surface of the window cannot be completely melted. Increasing the power supply of the camera requires a larger adapter, which results in a larger size of the camera and an increased cost.

[0037] In order to solve the above problems, Figures 1 to 4 As shown, the utility model first provides a deicing device, which can ensure the deicing effect and does not need to increase the power supply of the camera.

[0038] like Figure 1 and Figure 3 As shown, specifically, the de-icing device is used to de-ice the window 61 of the camera body 6, and includes a shell 1, a heating element 2 and an ice blade assembly 3, wherein: the shell 1 is arranged outside the camera body 6, and can reciprocate on the outer surface of the window 61; the heating element 2 is arranged on the shell 1, and can move together with the shell 1; the ice blade assembly 3 is arranged on the shell 1, and can move together with the shell 1, and the ice blade assembly 3 includes an ice blade body 31, and the ice blade body 31 can rotate independently relative to the shell 1 to break the ice covering the outer surface of the window 61.

[0039] In the de-icing device provided by the present invention, when the shell 1 reciprocates on the outer surface of the window 61, the ice blade body 31 and the heating element 2 both move with the shell 1, and at the same time the ice blade body 31 can rotate independently relative to the shell 1, so that the thicker ice covering the outer surface of the window 61 is broken, and the heating element 2 can heat the window 61 and the ice covering the outer surface of the window 61, so that the thin ice covering the outer surface of the window 61 melts, thereby ensuring that the ice on the outer surface of the window 61 can be completely removed, ensuring the de-icing effect, and enabling the camera to meet the use requirements of low temperature environments, expanding the scope of application, and there is no need to increase the power supply of the camera, thereby avoiding increasing the overall volume of the camera.

[0040] like Figures 2 to 3As shown, the ice blade assembly 3 also includes a first drive member 33 for driving the ice blade body 31 to rotate relative to the shell 1. Among them, the first drive member 33 can be set as a motor or other element that can drive the ice blade body 31 to rotate. The ice blade body 31 can be set to a cylindrical shape as shown in the figure, and the blades are arranged at intervals along the outer circumference of the ice blade body 31. The first drive member 33 drives the ice blade body 31 to rotate around the first rotation axis a relative to the shell 1, and the first rotation axis a is preferably parallel to the window 61. During the rotation process, all blades on the ice blade body 31 can scrape the ice surface to ensure the de-icing effect and improve the de-icing efficiency. Alternatively, the ice blade body 31 can also be set to a polygonal column shape, as long as it is ensured that at least some of the blades on the ice blade body 31 can scrape the ice surface during the rotation process, and the utility model does not make specific restrictions here.

[0041] like Figure 2 and Figure 4 As shown, the ice blade assembly 3 further includes a support member 32. When the support member 32 is supported on the outer surface of the window 61, there is a gap between the ice blade body 31 and the outer surface of the window 61. This can prevent the ice blade body 31 from contacting the outer surface of the window 61 and scratching the window 61, thereby protecting the window 61.

[0042] like Figure 3 to Figure 4 As shown, in the illustrated embodiment, the support member 32 is configured as a roller 321 that can rotate relative to the housing 1. Since the ice blade assembly 3 can move relative to the window 61 together with the housing 1, configuring the support member 32 as the roller 321 can reduce the friction between the support member 32 and the window 61, thereby preventing the ice blade assembly 3 and the housing 1 from getting stuck when moving relative to the window 61, and also preventing the support member 32 from scratching the window 61, thereby further protecting the window 61.

[0043] like Figure 2 As shown, the roller 321 is arranged coaxially with the blade body 31, that is, the axis of the roller 321 coincides with the first rotation axis a. The roller 321 can rotate with the blade body 31 relative to the housing 1 around the first rotation axis a, or can rotate with the blade body 31 relative to the housing 1 around the first rotation axis a. In addition, the diameter of the roller 321 is larger than the diameter of the blade body 31, so as to ensure that the blade body 31 will not contact the outer surface of the window 61 when rotating to any angle.

[0044] The axis of the roller 321 may also be parallel to the first rotation axis a, and the axis of the roller 321 is closer to the window 61 than the first rotation axis a, in which case the diameter of the roller 321 is smaller than the diameter of the ice blade body 31; or the axis of the roller 321 is parallel to the first rotation axis a, and the axis of the roller 321 is farther from the window 61 than the first rotation axis a, in which case the diameter of the roller 321 is larger than the diameter of the ice blade body 31. As long as it is ensured that the ice blade body 31 does not contact the outer surface of the window 61 when the roller 321 rotates to any angle, and the ice blade body 31 can break the thicker ice on the outer surface of the window 61, it will be sufficient.

[0045] Of course, in other embodiments, the support member 32 may also be configured as a protrusion or other structure, as long as it is ensured that the skate body 31 does not contact the outer surface of the window 61. The embodiment of the utility model does not make any specific limitation here.

[0046] like Figures 2 to 3 As shown, there are two support members 32, which are respectively disposed at both ends of the ice blade body 31. The two support members 32 can improve the stability of the ice blade body 31, prevent one side of the ice blade body 31 from tilting toward the window 61 and contacting the outer surface of the window 61, and also enable the ice blade body 31 to evenly break the ice on the outer surface of the window 61.

[0047] like Figures 2 to 3 As shown, the housing 1 is provided with a first mounting cavity 11, the opening of the first mounting cavity 11 faces the viewing window 61, and part of the ice blade body 31 is accommodated in the first mounting cavity 11. The housing 1 also has a second mounting cavity (not shown) connected to the first mounting cavity 11, the first driving member 33 is accommodated in the second mounting cavity, and the output end of the first driving member 33 extends into the first mounting cavity 11 and is connected to the ice blade body 31. The housing 1 prevents the ice blade body 31 and the first driving member 33 from being exposed, thereby protecting the ice blade body 31 and the first driving member 33. At the same time, the housing 1 can also prevent the ice blade body 31 from damaging other external structures during movement, thereby improving the safety of the de-icing device.

[0048] like Figure 3 As shown, the heating element 2 is disposed on the inner bottom wall of the first installation cavity 11, and the heating element 2 is not exposed, so that the housing 1 can also protect the heating element 2. In addition, the heating element 2 can heat the ice blade body 31 while heating the window 61, so as to enhance the effect of the ice blade body 31 on breaking ice on the outer surface of the window 61.

[0049] like Figures 2 to 3As shown, the deicing device further includes a wiper 4 disposed on the housing 1, the wiper 4 faces the viewing window 61 and can contact the viewing window 61. The housing 1 is further provided with a third mounting cavity 12 spaced apart from the first mounting cavity 11, the opening of the third mounting cavity 12 faces the viewing window 61, and part of the wiper 4 is accommodated in the third mounting cavity 12, so as to protect the wiper 4. The wiper 4 can clean the melted ice and water on the outer surface of the viewing window 61 to prevent the melted ice and water from refreezing, and also make the picture taken by the camera clearer, thereby ensuring the imaging effect of the camera.

[0050] like Figure 1 As shown, in one embodiment, the deicing device further includes a driving assembly 5, and the driving assembly 5 includes a second driving member 51 accommodated in the camera body 6, and the second driving member 51 is used to drive the housing 1 to reciprocate on the outer surface of the window 61. The second driving member 51 is accommodated in the camera body 6, which can prevent the second driving member 51 from being exposed and easily damaged. Among them, the second driving member 51 can be set as a component such as a motor that can drive the housing 1 to rotate. The second driving member 51 occupies a small space in the camera body 6 to avoid mutual interference with other components inside the camera body 6. In another embodiment, the driving assembly 5 can also drive the housing 1 to slide back and forth on the outer surface of the window 61.

[0051] The deicing device can not only clean the ice covering the outer surface of the window 61, but also clean the ice covering the surface of the camera housing, and the movement range of the housing 1 can be adjusted according to the size of the window 61 and the range to be cleaned by the deicing device. When the deicing device is only used to clean the window 61, the movement range of the housing 1 relative to the window 61 needs to cover part or all of the window 61.

[0052] like Figures 1 to 3As shown, the drive assembly 5 also includes a sleeve 52 and an elastic member 53, the two ends of the sleeve 52 are respectively connected to the second drive member 51 and the housing 1, and the housing 1 can rotate relative to the sleeve 52; the two ends of the elastic member 53 are respectively connected to the sleeve 52 and the housing 1, and can press the housing 1 toward the window 61. The sleeve 52 is connected to the output end of the second drive member 51, and can drive the housing 1, the heating element 2, the ice blade assembly 3 and the wiper 4 to rotate synchronously around the second rotation axis b relative to the window 61. The housing 1, the heating element 2, the ice blade assembly 3 and the wiper 4 can also rotate around the third rotation axis c relative to the sleeve 52 to get closer to or away from the window 61. Among them, the second rotation axis b is preferably perpendicular to the window 61, and the third rotation axis c is preferably parallel to the window 61 and perpendicular to the first rotation axis a. The elastic member 53 can apply a force to the shell 1 toward the window 61, so that the ice blade assembly 3 and the wiper 4 can be pressed against the outer surface of the window 61 or the ice on the outer surface of the window 61, and when the thickness of the ice covering the outer surface of the window 61 gradually decreases, the ice blade assembly 3 can also rotate relative to the sleeve 52 closer to the window 61, thereby enhancing the ice-breaking effect of the ice blade assembly 3 and the cleaning effect of the wiper 4.

[0053] Among them, the elastic member 53 can be a compression spring, a silicone member, a rubber member or the like that can apply pressure to the shell 1 toward the window 61 ; or, the elastic member 53 can also be a tension spring or the like that can apply a pulling force to the shell 1 toward the window 61 .

[0054] like Figure 1 As shown, the utility model also provides a camera, including a camera body 6 and the above-mentioned deicing device, and the camera body 6 has a window 61. The camera can meet the use requirements of low temperature environment and expand the scope of application.

[0055] Specifically, the camera body 6 includes a detachably connected front cover 62 and a rear barrel 63, the front cover 62 and the rear barrel 63 enclose an installation space, the front cover 62 is provided with a window 61 and a through hole spaced from the window, the second driving member 51 and the sleeve 52 are connected through the through hole. The camera body 6 also includes a lens 64 disposed in the installation space, and the lens 64 faces the window 61.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
