Description

Technical Field

[0001] This utility model relates to the field of camera equipment technology, and in particular to an imaging device. Background Technology

[0002] When freight trains and other wheel-rail trains are running on the track, the operating status of the trains must be monitored using TFDS (TrinFult Detection System).

[0003] like Figure 1 and Figure 2 As shown, the existing TFDS camera device typically includes a rectangular housing 1 and multiple cameras 2. The housing 1 has a window 10 at its top, and the cameras 2 are all housed inside the housing 1. During operation, multiple camera devices need to be sequentially installed between the sleepers on both sides of the track. To ensure that the camera 2 on one side of the sleeper can capture the lowest point of the train wheel flange on the guide rail at the top of the sleeper, the housing 1 of the camera device is usually tilted relative to the sleeper, so that the window 10 of the housing 1 faces the top edge of the guide rail at the top of the sleeper, and the lens of the camera 2 faces the window 10 at the top of the housing 1.

[0004] Since the lens of camera 2 needs to face the window 10 on the top of the housing 1, the camera 2 in the above-mentioned imaging device is usually erected inside the housing 1, which results in the housing 1 being relatively tall and large, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide an imaging device to alleviate the technical problem in the existing track TFDS that the camera in the imaging device is usually erected in the box, resulting in a high box height, large box size, and inconvenience of use.

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

[0007] The top of the housing assembly is provided with a first window, the camera assembly is disposed inside the housing assembly, and the lens of the camera assembly is arranged perpendicular to or relatively tilted to the first window.

[0008] The reflective structure is disposed within the housing assembly and is obliquely positioned between the first window and the lens of the camera assembly. The reflective structure is used to reflect 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 the track, and the side wall of the housing assembly near the sleeper is a first side wall;

[0010] The first sidewall has a bend at a position corresponding to the shoulder of the sleeper. The first sidewall is inclined from the bend to the top of the housing assembly toward the sleeper, so that the first sidewall can extend over the shoulder of the sleeper and over the sleeper.

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

[0012] In an optional embodiment, the housing assembly includes a cover and a housing, the cover being positioned over the housing;

[0013] The first window is located at the top of the cover, and the top of the shell is provided with a second window, which is opposite to the first window.

[0014] Both the camera assembly and the reflective structure are housed within the housing.

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

[0016] In an optional implementation, a cleaning component is also included;

[0017] A viewing plate is installed at the second window, and the cleaning component is movably installed inside the cover. The cleaning component is used to move above the viewing plate to clean it.

[0018] In an optional embodiment, a drive assembly is also included, which is installed inside the housing, and both the dustproof component and the cleaning component are connected to the output end of the drive assembly.

[0019] In an optional embodiment, a heating component is also included, which is installed inside the enclosure for supplying heat to the interior space of the enclosure.

[0020] In an optional embodiment, an air blowing assembly is also included, which is installed inside the cover and is used to blow air toward the second window.

[0021] In an optional embodiment, the opening edge of the cover is provided with a downwardly extending extension, the extension being annular, and the extension fitting and conforming to the periphery of the shell.

[0022] The imaging device provided by this utility model includes a housing assembly, a camera assembly, and a reflective structure. A first window is provided on the top of the housing assembly. The camera assembly is housed within the housing assembly, and its lens is perpendicular to or tilted relative to the first window. The reflective structure is housed within the housing assembly and is tilted between the first window and the lens of the camera assembly. The reflective structure reflects light passing through the first window back to the camera assembly. The imaging device provided by this utility model can be used in a TFDS system for train operation. During use, multiple imaging devices can be sequentially distributed along the width of the track between the sleepers on both sides of the track, with the first window of each imaging device facing upwards. For imaging devices positioned close to the sleepers, to ensure that the camera assembly in the imaging device can capture the lowest point of the train wheel flange on the guide rail at the top of the sleeper, the imaging device can be tilted relative to the sleeper so that the first window on the housing assembly faces the top edge of the guide rail. When a train passes over the guide rail, the camera module activates. Light from the scene outside the first window passes through the window and reaches the reflective structure, where it is reflected by the tilted structure and reaches the camera lens. This allows the camera to capture and monitor the scene outside the first window. Since the camera module captures the scene simply by receiving the reflected light, the lens does not need to face the window. Consequently, the camera module does not need to be vertically mounted within the housing. It can be tilted or horizontally mounted, reducing the height requirement of the housing and allowing for a smaller overall size. This not only meets the miniaturization requirements of the imaging device but also lowers the ground clearance of the first window, increasing the field of view and improving the user experience.

[0023] Compared with the prior art, the imaging device provided by this utility model uses a reflective structure to reflect the light passing through the first window to the lens of the camera component, thereby enabling the camera component to capture and monitor the scene outside the first window. The camera component does not need to be set up vertically so that the lens faces the first window. By adjusting the tilt angle of the reflective structure, the camera component can be set up horizontally inside the housing component, thereby effectively reducing the height of the housing component and meeting the miniaturization requirements of the imaging device.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Example:

[0038] like Figures 3-6 As shown, the imaging device provided in this embodiment includes a housing assembly 3, a camera assembly 4, and a reflective structure 5; the top of the housing assembly 3 is provided with a first window 30, the camera assembly 4 is disposed inside the housing assembly 3, and the lens of the camera assembly 4 is arranged perpendicularly to or relatively tilted to the first window 30; the reflective structure 5 is disposed inside the housing assembly 3, and the reflective structure 5 is tilted between the first window 30 and the lens of the camera assembly 4, and the reflective structure 5 is used to reflect the light passing through the first window 30 to the camera assembly 4.

[0039] The imaging device provided in this embodiment can be used in the TFDS system used in train operation. During use, such as... Figure 3 As shown, multiple imaging devices can be sequentially distributed between the sleepers 6 on both sides of the track along the width direction, with the first window 30 of each imaging device facing upwards. For imaging devices positioned close to the sleepers 6, to ensure that the camera component 4 in the imaging device can capture the lowest point of the train wheel flange on the top guide rail 61 of the sleeper 6, as shown... Figure 4 As shown, the imaging device can be 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 guide rail 61, camera component 4 is activated, at which point the scene light outside the first window 30 can be transmitted along... Figure 6 The arrow shown passes through the first window 30 and reaches the reflective structure 5, where it is then reflected by the tilted reflective structure 5 and reaches the lens of the camera component 4, thereby enabling the camera component 4 to capture and monitor the scene outside the first window 30.

[0041] Since the camera component 4 can capture images of the scene outside the first window 30 by receiving the light reflected from the reflective structure 5, the lens of the camera component 4 does not need to face the first window 30. Correspondingly, the camera component 4 does not need to be vertically installed inside the housing component 3. The camera component 4 can be tilted or horizontally installed inside the housing component 3. In this case, the space height requirement of the camera component 4 for the housing component 3 is reduced, and the overall height and size of the housing component 3 can be reduced. This not only meets the miniaturization requirements of the imaging device, but also reduces the height of the first window 30 from the ground, thereby increasing the 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 component 4, thereby enabling the camera component 4 to capture and monitor the scene outside the first window 30. The camera component 4 does not need to be set up vertically so that the lens faces the first window 30. By adjusting the tilt angle of the reflection structure 5, the camera component 4 can be set horizontally inside the housing component 3, thereby effectively reducing the height of the housing component 3 and meeting the miniaturization requirements of the imaging device.

[0043] Among them, the camera component 4 can be a camera, and the reflective structure 5 can be a reflector.

[0044] like Figure 4 and Figure 5 As shown, the housing assembly 3 is used to be placed on one side of the sleeper 6 of the track. The side wall of the housing assembly 3 near the sleeper 6 is the first side wall 31. The first side wall 31 has a bend 310 at the position corresponding to the shoulder 60 of the sleeper 6. The first side wall 31 is inclined from the bend 310 to the top of the housing assembly 3 in the direction close to the sleeper 6, so that the first side wall 31 can extend over the shoulder 60 of the sleeper 6 and extend above the sleeper 6.

[0045] The bend 310 on the first sidewall 31 of the housing assembly 3 is used to partially tilt the first sidewall 31 outward, so that the first sidewall 31 of the housing assembly 3 can avoid the shoulder 60 of the sleeper 6 and be positioned above the sleeper 6. Figure 4 As shown, at this time, the part of the housing assembly 3 located above the sleeper 6 is 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 flange on the guide rail 61 to the maximum extent, thus further effectively expanding the shooting range of the camera assembly 4.

[0046] like Figure 5 As shown, the side wall of the housing 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 junction of the top of the housing assembly 3 and the second side wall to the junction of the top of the housing assembly 3 and the first side wall 31.

[0047] When the first window 30 is strip-shaped, in order for the camera component 4 to still be able to capture images, the camera component 4 can be a linear camera.

[0048] When the first sidewall 31 of the housing assembly 3 is provided with a bend 310, the first window 30 extends from the junction of the top of the housing assembly 3 and the second sidewall to the junction of the top of the housing assembly 3 and the first sidewall 31. This allows the first window 30 at the top of the housing assembly 3 to extend to the position of the housing 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, further enabling the camera assembly 4 to capture the lowest point of the train wheel flange on the guide rail 61.

[0049] It should be noted that when the first window 30 is strip-shaped, the width of the first window 30 is narrow and the length is long. The narrow width of the first window 30 can effectively reduce the entry of dust, rain, snow and other impurities into the housing component 3, thus playing a dustproof role; the long length of the first window 30 can effectively increase the shooting field of the camera component 4.

[0050] like Figures 5-7 As shown, the housing assembly 3 includes a cover 7 and a housing 8, with the cover 7 covering the top of the housing 8; a first window 30 is located on the top of the cover 7, and a second window 80 is located on the top of the housing 8, with the second window 80 being opposite to the first window 30; the camera assembly 4 and the reflective structure 5 are both located inside the housing 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 component 4 through the reflection of the reflective structure 5. At this time, the camera component 4 can still capture and monitor the external scene.

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

[0053] It should be noted that existing camera devices typically... Figures 1-2 A baffle and a drive mechanism are provided at window 10. The drive mechanism is used to open or block window 10, thereby protecting the first window 30. Based on this, the existing camera device housing 1 not only houses the camera 2 but also the drive mechanism. The drive mechanism also increases the height of housing 1, thus... Figure 5As shown, even though the housing component 3 in the imaging device provided in this embodiment is composed of a cover 7 and a housing 8, the overall height and size of the imaging device provided in this embodiment are still smaller than those of existing camera devices.

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

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

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

[0057] The dustproof component 300 can be movably installed on the cover 7 by means of sliding connection, hinge, etc. In order to improve the ease of use of the dustproof component 300 and reduce the space occupied by the dustproof component 300 on the periphery of the housing assembly 3 when it moves, this embodiment preferably uses the sliding connection to movably install the dustproof component 300 on the cover 7.

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

[0059] The drive assembly 9 can employ a telescopic drive device such as a hydraulic cylinder or an electric push rod. The dustproof component 300 can be fitted against the outer wall of the cover 7. The output end of the drive assembly 9 is connected to a transmission rod, and the end of the transmission rod away from the drive assembly 9 passes through a clearance hole on the cover 7 and connects to the dustproof component 300. The drive assembly 9 is used to drive the dustproof component 300 to move closer to or further away from the first window 30 at the top of the cover 7, thereby enabling the dustproof component 300 to block or open the first window 30.

[0060] To further reduce the size of the imaging device, the dustproof component 300 is preferably plate-shaped in this embodiment.

[0061] It should be noted that when the first window 30 is strip-shaped, the dustproof component 300 can slide and connect with the cover 7 along the length direction perpendicular to the first window 30. At this time, the dustproof component 300 only needs to move a short distance to block or open the first window 30. Correspondingly, the output stroke of the drive component 9 is also small, and it does not need to occupy too much space inside the cover 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 also includes a cleaning component 70; a viewing plate 800 is installed at the second window 80, and the cleaning component 70 is movably installed inside the cover 7. The cleaning component 70 is used to move above the viewing plate 800 to clean the viewing plate 800.

[0063] The transparent panel 800 can be made of glass or plastic. During use, the transparent panel 800 can ensure the light transmittance 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 open during the operation of the camera component 4, dust and other impurities may enter the housing 7 and fall onto the perspective plate 800. In order to prevent impurities from contaminating the perspective plate 800 and affecting the shooting effect, the cleaning component 70 can be driven to move above the perspective plate 800, thereby wiping the perspective plate 800 with the cleaning component 70.

[0065] The cleaning component 70 can be a cleaning brush or a cleaning sponge, or it can be a wiper mechanism.

[0066] In order not to interfere with the operation of the camera assembly 4, the viewing plate 800 can be wiped with the cleaning component 70 after each operation of the camera assembly 4. Since the first window 30 is blocked by the dustproof component 300 after the camera assembly 4 is finished, no more impurities will fall on the viewing plate 800 after wiping, and the cleanliness of the viewing plate 800 can be guaranteed at this time.

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

[0068] like Figure 7As shown, the cleaning component 70 can be connected to the output end of the drive assembly 9 via the pressure rod 700. Specifically, the pressure rod 700 is hinged to the output end of the drive assembly 9, and an elastic element is connected between the pressure rod 700 and the output end of the drive assembly 9. The elastic element is used to apply pressure to the pressure rod 700 so that the pressure rod 700 presses down on the cleaning component 70. Under the pressure of the pressure rod 700, the cleaning component 70 is stably pressed against the top of the transparent plate 800. When the drive assembly 9 drives the cleaning component 70 to reciprocate above the transparent plate 800, it can effectively increase the friction between the cleaning component 70 and the transparent plate 800, thereby improving the cleaning effect.

[0069] It can be seen that the elastic element and the pressure rod 700 can work together to effectively improve the cleaning effect of the cleaning element 70 on the transparent plate 800.

[0070] like Figure 6 As shown, a liquid spraying assembly 71 can also be installed inside the cover 7. The liquid spraying assembly 71 includes a nozzle, which is positioned toward the transparent plate 800. The liquid spraying assembly 71 is used to spray cleaning liquid onto the transparent plate 800.

[0071] When the cleaning component 70 moves back and forth above the viewing plate 800, the spraying component 71 is activated and sprays cleaning liquids such as pure water onto the viewing plate 800, thereby further improving the cleaning effect of the viewing plate 800.

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

[0073] Since the imaging device is exposed to the outside world during use, moisture may enter the housing 7 in rainy or snowy weather. To prevent moisture from adhering to the perspective plate 800 and affecting the shooting effect, the heating component 72 can be activated. At this time, the heating component 72 will supply heat to the interior space of the housing 7 to evaporate the moisture.

[0074] In addition, when the spraying component 71 is installed inside the cover 7, the heating component 72 can be activated after cleaning the transparent plate 800. At this time, the heating component 72 can be used to evaporate the water adhering to the transparent plate 800 and the inner wall of the cover 7, thereby preventing residual water from affecting the shooting effect.

[0075] To improve the performance of the heating element 72, such as Figure 6 As shown, the heating component 72 can be located near the transparent plate 800. In order to prevent the heating component 72 from affecting the light transmission process between the first window 30 and the second window 80, the projection of the heating component 72 on the plane of the transparent plate 800 needs to be located on one side of the transparent plate 800.

[0076] The heating component 72 can be an electric heater. To improve the performance of the heating component 72, it can be a heater with a constant temperature function. In rainy or snowy weather, the heating component 72 can remain on and maintain a constant temperature during the operation of the camera component 4.

[0077] like Figure 6 As shown, the imaging device provided in this embodiment also includes an air blowing assembly 73, which is installed inside the cover 7 and is used to blow air to the second window 80.

[0078] The air blowing component 73 can always be in the open state during the operation of the camera component 4, so that it can continuously blow air into the second window 80, creating a negative pressure inside the cover 7, effectively preventing external dust and other impurities from passing through the second window 80 and falling onto the viewing plate 800.

[0079] The air blowing assembly 73 can adopt a blowing structure such as a fan. The air blowing assembly 73 includes an air outlet. To improve the performance of the air blowing assembly 73, such as... Figure 6 As shown, the air outlet of the air blowing assembly 73 can be located near the second window 80, and the air outlet can be tilted so that the air outlet channel on it faces the second window 80.

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

[0081] like Figure 8 As shown, when the housing assembly 3 includes a cover 7 and a housing 8, the opening edge of the cover 7 may be provided with a downwardly extending extension 74. The extension 74 is annular and is fitted and attached to the periphery of the housing 8.

[0082] The extension 74 can serve as a dustproof feature, effectively preventing impurities such as rain, snow, and dust from entering the cover 7 through the gap between the cover 7 and the shell 8.

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

[0084] As can be seen, the imaging device provided in this embodiment, by setting up a dustproof component 300, a cleaning component 70, a liquid spraying component 71, a heating component 72, a blowing component, and an extension part 74, can effectively optimize the dustproof effect of the imaging device and the cleaning effect at the transparent plate 800, thereby minimizing the manual maintenance process and enabling the imaging device to have a maintenance-free function.

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

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

[0087] The cover 7 and the housing 8 can be detachably connected using fasteners such as screws, clips, and pins. To improve the stability of the connection between the cover 7 and the housing 8, such as... Figure 8 As shown, in this embodiment, one side of the cover 7 is hinged to one side of the housing 8 via a hinge shaft, and the other side of the cover 7 is snapped together with the other side of the housing 8 via a snap fastener.

[0088] This configuration allows the cover 7 to be flipped relative to the housing 8. When it is necessary to manually clean the transparent panel 800, the cover 7 can be flipped directly on the housing 8 to open the cover 7, further improving the ease of installation and removal of the cover 7.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
