Description

Technical Field

[0001] The present invention relates to the technical field of camera equipment, and in particular to an imaging device. Background Art

[0002] When freight trains and other wheel-rail trains are running on the track, TFDS (Freight Train Fault Dynamic Detection System, abbreviated as TFDS) is required to monitor the running status of the train.

[0003] like Figure 1 and Figure 2 As shown, the camera device used in the existing TFDS usually includes a rectangular box 1 and a plurality of cameras 2, wherein a window 10 is opened on the top of the box 1, and the plurality of cameras 2 are all arranged in the box 1. During use, a plurality of camera devices need to be arranged in sequence between the sleepers on both sides of the track. In order to enable the camera 2 of the camera device on one side of the sleeper to capture the lowest end of the train wheel rim on the top rail of the sleeper, the box 1 in the camera device is usually tilted relative to the sleeper, so that the window 10 of the box 1 faces the top edge of the top rail of the sleeper, and the lens of the camera 2 needs to face the window 10 on the top of the box 1.

[0004] Since the lens of the camera 2 needs to face the window 10 on the top of the box 1, the camera 2 in the above-mentioned camera device is usually erected in the box 1, which results in a high height and a large size of the box 1, which is not convenient to use. Summary of the invention

[0005] The object of the present invention is to provide an imaging device to alleviate the technical problem that the camera in the imaging device adopted by the track TFDS in the prior art is usually erected in a box, resulting in a high height of the box, a large size of the box, and inconvenient use.

[0006] In a first aspect, the present invention provides an imaging device, comprising a housing component, a camera component and a reflection structure;

[0007] A first window is provided on the top of the shell assembly, the camera assembly is arranged in the shell assembly, and the lens of the camera assembly and the first window are arranged perpendicularly or relatively inclined to each other;

[0008] The reflective structure is disposed in the housing assembly, and the reflective structure is obliquely disposed between the first window and the lens of the camera assembly, and the reflective structure is used to reflect the light passing through the first window to the camera assembly.

[0009] In an optional embodiment, the housing assembly is used to be placed on one side of a sleeper of a track, and the side wall of the housing assembly close to the sleeper is a first side wall;

[0010] A bending part is provided at a position of the first side wall corresponding to the shoulder of the sleeper, and the first side wall is inclined from the bending part to the top of the shell assembly toward the direction close to the sleeper, so that the first side wall can pass over the shoulder of the sleeper and extend above the sleeper.

[0011] In an optional embodiment, the side wall of the shell assembly facing away from the sleeper is the second side wall, the first window is strip-shaped, and the first window extends from the intersection of the top of the shell assembly and the second side wall to the intersection of the top of the shell assembly and the first side wall.

[0012] In an optional embodiment, the housing assembly includes a cover body and a housing, and the cover body is disposed above the housing;

[0013] The first window is arranged at the top of the cover body, and the top of the shell body is provided with a second window, and the second window is opposite to the first window;

[0014] The camera assembly and the reflective structure are both arranged in the shell.

[0015] In an optional embodiment, a dustproof piece is further included, which is movably mounted on the cover body and is used to move above the first window to cover or open the first window.

[0016] In an optional embodiment, a cleaning member is also included;

[0017] A perspective plate is installed at the second window, and the cleaning member is movably installed in the cover body. The cleaning member is used to move above the perspective plate to clean the perspective plate.

[0018] In an optional embodiment, a driving assembly is further included, wherein the driving assembly is installed in the cover body, and the dustproof component and the cleaning component are both connected to the output end of the driving assembly.

[0019] In an optional embodiment, a heating component is further included, and the heating component is installed in the cover body to provide heat to the internal space of the cover body.

[0020] In an optional embodiment, it also includes a blowing assembly, which is installed in the cover body and is used for blowing air toward the second window.

[0021] In an optional embodiment, an extension portion extending downward is provided at the opening edge of the cover body, the extension portion is annular, and the extension portion is sleeved and fits against the peripheral side of the shell.

[0022] The imaging device provided by the present invention includes a shell assembly, a camera assembly and a reflection structure; a first window is provided on the top of the shell assembly, the camera assembly is arranged in the shell assembly, and the lens of the camera assembly is perpendicular to or relatively inclined to the first window; the reflection structure is arranged in the shell assembly, and the reflection structure is arranged obliquely between the first window and the lens of the camera assembly, and the reflection structure is used to reflect the light passing through the first window to the camera assembly. The imaging device provided by the present invention can be used in the TFDS system adopted in train operation. During use, multiple imaging devices can be distributed in sequence between the sleepers on both sides of the track along the width direction of the track, and the first window in each imaging device is arranged upward. For the imaging device arranged close to the sleeper, in order to enable the camera assembly in the imaging device to capture the lowest end of the train wheel rim on the top rail of the sleeper, the imaging device can be arranged obliquely relative to the sleeper so that the first window on the shell assembly faces the top edge of the rail. When a train passes on the guide rail, the camera assembly is activated. At this time, the scene light outside the first window can pass through the first window and reach the reflective structure, and then be reflected by the tilted reflective structure to reach the lens of the camera assembly, so that the camera assembly can shoot and monitor the scene outside the first window. Since the camera assembly can shoot the scene outside the first window by receiving the light reflected by the reflective structure, the lens of the camera assembly does not need to be set facing the first window. Correspondingly, the camera assembly does not need to be set upright in the shell assembly. The camera assembly can be tilted or horizontally set in the shell assembly. At this time, the camera assembly has a lower spatial height requirement for the shell assembly, and the overall height and size of the shell assembly can be reduced, which can not only meet the miniaturization requirements of the imaging device, but also reduce the height of the first window from the ground, thereby increasing the shooting field of view of the imaging device and improving the user experience of the imaging device.

[0023] Compared with the prior art, the imaging device provided by the present invention uses a reflective structure so that the light passing through the first window can be reflected to the lens of the camera assembly, thereby realizing the camera assembly to shoot and monitor the scene outside the first window. The camera assembly does not need to be arranged upright so that the lens faces the first window. By adjusting the inclination angle of the reflective structure, the camera assembly can be horizontally arranged in the shell assembly, thereby effectively reducing the height of the shell assembly and meeting the miniaturization requirements of the imaging device.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] Example:

[0038] like Figure 3-Figure 6 As shown, the imaging device provided in this embodiment includes a shell component 3, a camera component 4 and a reflection structure 5; a first window 30 is provided on the top of the shell component 3, the camera component 4 is arranged in the shell component 3, and the lens of the camera component 4 and the first window 30 are perpendicular to each other or relatively inclined; the reflection structure 5 is arranged in the shell component 3, and the reflection structure 5 is inclined between the first window 30 and the lens of the camera component 4, and the reflection structure 5 is used to reflect the light passing through the first window 30 to the camera component 4.

[0039] The imaging device provided in this embodiment can be used in the TFDS system used in train operation. During use, Figure 3 As shown in FIG. 1 , a plurality of imaging devices can be sequentially distributed between the sleepers 6 on both sides of the track along the width direction of the track, and the first window 30 in each imaging device is set upward. For the imaging device arranged near the sleeper 6, in order to enable the camera assembly 4 in the imaging device to capture the lowest end of the train wheel flange on the top guide rail 61 of the sleeper 6, as shown in FIG. Figure 4 As shown, the imaging device can be arranged tilted relative to the sleeper 6 so that the first window 30 on the housing assembly 3 faces the top edge of the guide rail 61 .

[0040] When a train passes on the guide rail 61, the camera assembly 4 is activated, and the scene light outside the first window 30 can be seen along the Figure 6 The light in the direction of the arrow passes through the first window 30 and reaches the reflective structure 5 , and is then reflected by the tilted reflective structure 5 to reach the lens of the camera assembly 4 , thereby enabling the camera assembly 4 to shoot and monitor the scene outside the first window 30 .

[0041] Since the camera component 4 can shoot the scene outside the first window 30 by receiving the light reflected by the reflective structure 5, the lens of the camera component 4 does not need to be set facing the first window 30. Correspondingly, the camera component 4 does not need to be set upright in the shell component 3. The camera component 4 can be set at an angle or horizontally in the shell component 3. At this time, the camera component 4 has a lower spatial height requirement for the shell component 3, and the overall height and size of the shell component 3 can be reduced, which can not only meet the miniaturization requirements of the imaging device, but also reduce the height of the first window 30 from the ground, thereby increasing the shooting field of view of the imaging device and improving the user experience of the imaging device.

[0042] Compared with the prior art, the imaging device provided in this embodiment uses the reflection structure 5 to reflect the light passing through the first window 30 to the lens of the camera assembly 4, thereby enabling the camera assembly 4 to shoot and monitor the scene outside the first window 30. The camera assembly 4 does not need to be set upright so that the lens faces the first window 30. By adjusting the inclination angle of the reflection structure 5, the camera assembly 4 can be horizontally set in the shell assembly 3, thereby effectively reducing the height of the shell assembly 3 and meeting the miniaturization requirements of the imaging device.

[0043] The camera assembly 4 may be a camera, and the reflective structure 5 may be a reflector.

[0044] like Figure 4 and Figure 5 As shown, the shell assembly 3 is used to be placed on one side of the sleeper 6 of the track, and the side wall of the shell assembly 3 close to the sleeper 6 is the first side wall 31; a bending portion 310 is provided at a position of the first side wall 31 corresponding to the shoulder 60 of the sleeper 6, and the first side wall 31 is inclined from the bending portion 310 to the top of the shell assembly 3 toward the direction close to the sleeper 6, so that the first side wall 31 can pass over the shoulder 60 of the sleeper 6 and extend above the sleeper 6.

[0045] The bend 310 on the first side wall 31 of the housing assembly 3 is used to make the first side wall 31 of the housing assembly 3 partially tilt outward, so that the first side wall 31 of the housing assembly 3 can avoid the shoulder 60 of the sleeper 6 and be located above the sleeper 6. Figure 4 As shown, at this time, the portion of the shell assembly 3 located above the sleeper 6 is arranged adjacent to the guide rail 61 on the sleeper 6, which allows the camera assembly 4 to capture the lowest end of the train wheel rim on the guide rail 61 to the maximum extent, further effectively expanding the shooting range of the camera assembly 4.

[0046] like Figure 5 As shown, the side wall of the shell assembly 3 facing away from the sleeper 6 is the second side wall, the first window 30 is strip-shaped, and the first window 30 extends from the intersection of the top of the shell assembly 3 and the second side wall to the intersection of the top of the shell assembly 3 and the first side wall 31.

[0047] When the first window 30 is in a strip shape, in order to enable the camera assembly 4 to still capture images, the camera assembly 4 may be a linear camera.

[0048] When a bend 310 is provided on the first side wall 31 of the shell assembly 3, the first window 30 extends from the intersection of the top of the shell assembly 3 and the second side wall to the intersection of the top of the shell assembly 3 and the first side wall 31, so that the first window 30 at the top of the shell assembly 3 can extend to the position of the shell assembly 3 above the sleeper 6, so that the top edge of the guide rail 61 on the sleeper 6 can fall within the range of the first window 30, and further the camera assembly 4 can capture the lowermost end of the train wheel rim on the guide rail 61.

[0049] It should be noted that when the first window 30 is in a strip shape, the width of the first window 30 is narrower and the length is longer. The narrow width of the first window 30 can effectively reduce the entry of impurities such as dust, rain and snow into the shell assembly 3, thereby playing a dust-proof role; the long length of the first window 30 can effectively increase the shooting field of view of the camera assembly 4.

[0050] like Figure 5-Figure 7 As shown, the shell assembly 3 includes a cover body 7 and a shell 8, the cover body 7 is arranged above the shell 8; the first window 30 is arranged on the top of the cover body 7, and the top of the shell 8 is provided with a second window 80, and the second window 80 is opposite to the first window 30; the camera assembly 4 and the reflection structure 5 are both arranged in the shell 8.

[0051] Since the second window 80 is opposite to the first window 30, external light can reach the second window 80 through the first window 30, then reach the reflective structure 5 through the second window 80, and then reach the lens of the camera assembly 4 through reflection of the reflective structure 5. At this time, the camera assembly 4 can still realize the shooting and monitoring process of the external scene.

[0052] When the shell assembly 3 includes the cover body 7 and the shell 8 , the cover body 7 can be used to protect the second window 80 to reduce external impurities such as dust, rain and snow from entering the second window 80 , thereby reducing the contamination of the reflective structure 5 by the impurities.

[0053] It should be noted that existing camera devices usually Figure 1-Figure 2 The window 10 shown in the figure is provided with a baffle and a driving mechanism, and the driving mechanism is used to drive the baffle to open or cover the window 10, so as to protect the first window 30. Based on this, the box 1 of the existing camera device is not only equipped with a camera 2, but also equipped with a driving mechanism, and the driving mechanism will also increase the height of the box 1, so as to Figure 5 As shown, even though the housing assembly 3 in the imaging device provided in this embodiment is composed of a cover body 7 and a housing 8, compared with the existing camera device, the overall height and size of the imaging device provided in this embodiment are still smaller.

[0054] To better protect the first window 30 and the second window 80, as Figure 5 and Figure 6 As shown, the imaging device provided in this embodiment further includes a dustproof member 300 , which is movably mounted on the cover body 7 , and is used to move above the first window 30 to cover or open the first window 30 .

[0055] When the camera assembly 4 stops working, the dustproof piece 300 moves to the top of the first window 30 to cover the first window 30 . At this time, the dustproof piece 300 can effectively prevent external impurities from entering the shell assembly 3 , further reducing the contamination of the reflective structure 5 by impurities.

[0056] When the camera assembly 4 is started, the dustproof piece 300 can move on the cover body 7 away from the first window 30 , thereby opening the first window 30 and preventing the dustproof piece 300 from affecting the shooting process of the camera assembly 4 .

[0057] The dustproof part 300 can be movably installed on the cover body 7 by means of sliding connection, hinge, etc. In order to improve the convenience of use of the dustproof part 300 and reduce the space occupied by the surrounding side of the shell assembly 3 when the dustproof part 300 moves, in this embodiment, the dustproof part 300 is preferably movably installed on the cover body 7 by means of sliding connection.

[0058] The movement of the dustproof member 300 on the cover body 7 can be realized by human or mechanical drive, in order to reduce the manual labor, such as Figure 6 and Figure 7 As shown, the preferred imaging device of this embodiment further includes a driving component 9 , which is installed in the cover body 7 , and the dustproof member 300 is connected to the output end of the driving component 9 .

[0059] The driving assembly 9 can adopt a telescopic driving device such as an oil cylinder or an electric push rod, and the dustproof member 300 can be attached to the outer wall of the cover body 7. The output end of the driving assembly 9 is connected to a transmission rod, and the end of the transmission rod away from the driving assembly 9 passes through the clearance hole on the cover body 7 and is connected to the dustproof member 300. The driving assembly 9 is used to drive the dustproof member 300 to move close to or away from the first window 30 at the top of the cover body 7, so as to achieve the covering or opening of the first window 30 by the dustproof member 300.

[0060] In order to further reduce the size of the imaging device, in this embodiment, the dustproof member 300 is preferably in a plate shape.

[0061] It should be noted that when the first window 30 is strip-shaped, the dustproof piece 300 can be slidably connected to the cover body 7 along the length direction perpendicular to the first window 30. At this time, the dustproof piece 300 only needs to move a short distance to cover or open the first window 30. Correspondingly, the output stroke of the driving component 9 is also small, and there is no need to occupy too much space in the cover body 7, which can further reduce the size of the imaging device.

[0062] like Figure 6 and Figure 7 As shown, the imaging device provided in this embodiment further includes a cleaning member 70 ; a perspective plate 800 is installed at the second window 80 , and the cleaning member 70 is movably installed in the cover body 7 , and the cleaning member 70 is used to move above the perspective plate 800 to clean the perspective plate 800 .

[0063] The perspective plate 800 can be made of a glass plate or a plastic plate. During use, the perspective plate 800 can ensure the transmittance of light at the second window 80 and can seal the second window 80 to effectively prevent dust and other impurities from entering the housing 8.

[0064] Since the first window 30 is in an open state during the operation of the camera assembly 4, there is a possibility that dust and other impurities enter the cover body 7 and fall on the perspective plate 800. In order to prevent the impurities from contaminating the perspective plate 800 and affecting the shooting effect, the cleaning member 70 can be driven to move above the perspective plate 800, so that the cleaning member 70 can be used to wipe the perspective plate 800.

[0065] The cleaning member 70 may be a cleaning brush or a cleaning sponge, or a windshield wiper structure.

[0066] In order not to interfere with the working process of the camera assembly 4, each time the camera assembly 4 finishes working, the perspective plate 800 can be wiped with the cleaning piece 70. Since the first window 30 is blocked by the dustproof piece 300 after the camera assembly 4 finishes working, no impurities will fall from the wiped perspective plate 800. At this time, the cleanliness of the perspective plate 800 can be guaranteed.

[0067] Furthermore, the cleaning member 70 can also be moved by mechanical drive. In order to save energy and save space in the cover body 7, the present embodiment preferably connects the cleaning member 70 to the output end of the aforementioned driving component 9. At this time, the cleaning member 70 and the dustproof member 300 share the same power source, which can effectively reduce the mechanical structure in the imaging device and further meet the miniaturization requirements of the imaging device.

[0068] like Figure 7 As shown, the cleaning member 70 can be connected to the output end of the driving assembly 9 through a pressure rod 700. Specifically, the pressure rod 700 and the output end of the driving assembly 9 are hinged and an elastic member is connected between the pressure rod 700 and the output end of the driving assembly 9. The elastic member is used to apply pressure to the pressure rod 700 so that the pressure rod 700 presses down the cleaning member 70. The cleaning member 70 is stably abutted against the top of the perspective plate 800 under the pressure of the pressure rod 700. When the driving assembly 9 drives the cleaning member 70 to reciprocate above the perspective plate 800, the friction between the cleaning member 70 and the perspective plate 800 can be effectively increased, thereby improving the cleaning effect.

[0069] It can be seen that the elastic member and the pressure rod 700 can cooperate with each other to effectively improve the cleaning effect of the cleaning member 70 on the perspective plate 800.

[0070] like Figure 6 As shown, a liquid spraying assembly 71 may also be installed in the cover body 7. The liquid spraying assembly 71 includes a nozzle. The nozzle is arranged toward the perspective plate 800. The liquid spraying assembly 71 is used to spray cleaning liquid onto the perspective plate 800.

[0071] When the cleaning member 70 reciprocates above the perspective plate 800 , the liquid spraying assembly 71 is activated and sprays a cleaning liquid such as pure water to the perspective plate 800 , thereby further improving the cleaning effect of the perspective plate 800 .

[0072] like Figure 6 and Figure 7 As shown, the imaging device provided in this embodiment further includes a heating component 72 , which is installed in the cover body 7 and is used to supply heat to the internal space of the cover body 7 .

[0073] Since the imaging device is exposed to the outside world during use, moisture will enter the cover body 7 in rainy and snowy weather. In order to prevent the moisture from adhering to the perspective plate 800 and affecting the shooting effect, the heating component 72 can be started. At this time, the heating component 72 will supply heat to the internal space of the cover body 7 to evaporate the moisture.

[0074] In addition, when a liquid spraying assembly 71 is installed in the cover body 7, the heating assembly 72 can also be started after cleaning the perspective plate 800. At this time, the heating assembly 72 can be used to evaporate the moisture attached to the perspective plate 800 and the inner wall of the cover body 7, thereby preventing the residual moisture from affecting the shooting effect.

[0075] To improve the use effect of the heating component 72, as Figure 6 As shown, the heating component 72 can be arranged at a position close to the perspective plate 800, and in order to prevent the heating component 72 from affecting the light penetration process between the first window 30 and the second window 80, the projection of the heating component 72 on the plane where the perspective plate 800 is located needs to be located on one side of the perspective plate 800.

[0076] The heating component 72 can be an electric heater. To improve the use effect of the heating component 72, the heating component 72 can be a heater with a constant temperature function. When encountering rainy and snowy weather, the heating component 72 can always be turned on and maintain a constant temperature during the operation of the camera assembly 4.

[0077] like Figure 6 As shown, the imaging device provided in this embodiment further includes an air blowing component 73 , which is installed in the cover body 7 and is used for blowing air toward the second window 80 .

[0078] The blowing assembly 73 can always be in the open state during the operation of the camera assembly 4, so that air can be continuously blown toward the second window 80, so that negative pressure is formed in the cover body 7, effectively preventing external dust and other impurities from passing through the second window 80 and falling onto the perspective plate 800.

[0079] The blowing assembly 73 may adopt a blowing structure such as a blower, and the blowing assembly 73 includes an air outlet. To improve the use effect of the blowing assembly 73, Figure 6 As shown, the air outlet nozzle of the blowing assembly 73 may be disposed near the second window 80 , and the air outlet nozzle may be tilted so that the air outlet channel thereon faces the second window 80 .

[0080] It should be noted that in order to prevent the blowing assembly 73 from affecting the light penetration process between the first window 30 and the second window 80 , the projection of the air outlet of the blowing assembly 73 on the plane where the second window 80 is located needs to be located on one side of the second window 80 .

[0081] like Figure 8 As shown, when the shell assembly 3 includes a cover body 7 and a shell 8, an extension portion 74 extending downward may be provided at the opening edge of the cover body 7. The extension portion 74 is annular and is sleeved and fitted to the peripheral side of the shell 8.

[0082] The extension portion 74 can play a dustproof role, effectively preventing impurities such as rain, snow, and dust from entering the cover body 7 along the gap between the cover body 7 and the shell 8.

[0083] In order to improve the dustproof effect of the extension part 74, in this embodiment, the vertical distance between the upper edge and the lower edge of the extension part 74 is preferably 20 mm. The upper edge of the extension part 74 refers to the edge of the extension part 74 located at the opening of the cover body 7, and correspondingly, the lower edge of the extension part 74 refers to the edge of the extension part 74 away from the opening of the cover body 7.

[0084] It can be seen that the imaging device provided in this embodiment can effectively optimize the dust-proof effect of the imaging device and the cleaning effect at the perspective plate 800 by arranging the dust-proof part 300, the cleaning part 70, the liquid spraying component 71, the heating component 72, the blowing component and the extension part 74, thereby minimizing the manual maintenance process and making the imaging device have a maintenance-free function.

[0085] In addition, when the housing assembly 3 includes the cover body 7 and the housing 8, the cover body 7 and the housing 8 can be connected to each other in a detachable connection manner.

[0086] The detachable connection between the cover body 7 and the shell 8 can effectively improve the convenience of installation and removal of the cover body 7. When the cleaning member 70 fails or the image is unclear, it is convenient to open the cover body 7 to manually clean the perspective plate 800 at the second window 80.

[0087] The cover body 7 and the housing 8 can be detachably connected by fasteners such as screws, buckles, and latches. In order to improve the connection stability between the cover body 7 and the housing 8, as shown in FIG. Figure 8 As shown, in this embodiment, one side of the cover body 7 is preferably hinged to one side of the shell 8 via a hinge shaft, and the other side of the cover body 7 is snap-connected to the other side of the shell 8 via a buckle.

[0088] This arrangement allows the cover body 7 to be flipped relative to the shell 8. When the perspective plate 800 needs to be manually cleaned, the cover body 7 can be directly flipped on the shell 8 to open the cover body 7, further improving the convenience of installation and removal of the cover body 7.
