Description

Technical Field

[0001] The utility model relates to the technical field of track equipment, in particular to a vehicle-mounted observation device. Background Art

[0002] With the advancement of technology, the beyond-visual-range systems suitable for rail locomotives are becoming more and more perfect and their functions are becoming more and more powerful. The locomotive beyond-visual-range systems can effectively improve driving safety and have begun to be widely used on rail locomotives.

[0003] At present, the existing locomotive beyond-visual-range systems are usually equipped with on-board lookout devices, multi-dimensional lidar devices, beyond-visual-range early warning devices and intelligent analyzers. The configuration of lidar and intelligent analyzers can allow the driver to know the situation on the track 1 km or even farther ahead in advance, so that the driver can detect whether there are any abnormalities ahead earlier, for example, whether there are obstacles or pedestrians on the track ahead, whether geological disasters have occurred, etc. If there are situations that affect the safe driving of the train, the driver can slow down or stop in advance to ensure driving safety.

[0004] The vehicle-mounted observation device can be used alone or integrated in the locomotive beyond-visual-range system. The existing vehicle-mounted observation device usually includes a protective shell, a number of beyond-visual-range cameras (or simply cameras) arranged in the protective shell, and a circuit board arranged in the protective shell. The protective shell can protect the internal cameras, circuit boards, etc., and a light-transmitting plate (such as light-transmitting glass) is arranged at the position corresponding to the camera on the protective shell, so that the internal camera can collect external images or pictures through the light-transmitting plate, so that the driver can judge whether there is any abnormality ahead.

[0005] In the prior art, the on-board observation device is usually installed above the front of the locomotive to collect images or pictures in front. However, in actual application, since the on-board observation device is exposed to the air, the inner surface of the light-transmitting plate is very easy to fog, so that the camera cannot clearly collect the external images or pictures through the light-transmitting plate, thereby affecting the effect of the locomotive beyond-visual-range system.

[0006] Therefore, it is desirable in the art to provide a vehicle-mounted observation device to solve the above-mentioned technical problems. Utility Model Content

[0013] In one embodiment, a connecting port is provided at the side ends of the first defogger and the second defogger, and the first defogger and the second defogger are connected to each other through the connecting port.

[0014] In one embodiment, a first opening is provided on the front plate, and the light-transmitting plate is fixed in the first opening.

[0015] The housing includes a rear plate arranged opposite to the front plate and having a second opening, and a rear cover for closing the second opening.

[0016] In one embodiment, the shell further includes a top cover arranged above the front plate and the rear plate, a windward surface and a leeward surface arranged on the top cover and connected to each other, and side edge surfaces arranged on both sides of the windward surface and the leeward surface, wherein heat dissipation fins are provided on the outer surfaces of the windward surface and the rear cover.

[0017] In one embodiment, the connecting frame is located below the shell, and the shell further includes a side plate arranged between the front plate and the rear plate, and a bottom plate arranged opposite to the top cover, wherein a guide plate for guiding airflow to flow toward the connecting frame is provided between the front plate and the bottom plate.

[0018] In one embodiment, the front plate, the rear plate, the windward surface and the guide plate are all arranged at an angle.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than an exhaustive list of all embodiments. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0038] The utility model will be further described below in conjunction with the accompanying drawings.

[0039] Example 1

[0040] See also Figure 1 and 3In this embodiment, a vehicle-mounted observation device 100 is provided, including a housing 1, and an inner cavity 11 for placing a camera device is formed in the housing 1. In implementation, the shape of the housing 1 can be determined according to actual needs, as long as it can enclose the inner cavity 11. For example, in implementation, the housing 1 can be constructed as a square structure, a cylindrical structure, etc., so as to effectively isolate and protect the internal devices.

[0041] Preferably, a light-transmitting plate 2 is also provided on the front plate 12 of the housing 1, such as Figure 1 and 2 As shown, the camera device arranged in the inner cavity 11 can collect external images or pictures through the light-transmitting plate 2. In implementation, the light-transmitting plate 2 can be a glass plate, a transparent plastic plate, etc. In this embodiment, the light-transmitting plate 2 is a glass plate.

[0042] like Figure 1 and 3 As shown, in this embodiment, the housing 1 includes a front plate 12 facing the front end, a rear plate 14 arranged opposite to the front plate 12, a top cover 16 arranged above the front plate 12 and the rear plate 14, a bottom plate 15 arranged opposite to the top cover 16, and a side plate 13 arranged between the front plate 12 and the rear plate 14. Thus, the front plate 12, the side plate 13, the rear plate 14, the bottom plate 15 and the top cover 16 can together enclose the inner cavity 11, as shown in FIG. Figure 5 As shown, the light-transmitting plate 2 is disposed on the front plate 12 so as to capture images or pictures in front.

[0043] In one embodiment, the top cover 16 can be detachably connected to the housing 1 by fasteners such as bolts or screws. Accordingly, the top cover 16 is configured with a plurality of through holes 84, such as Figure 4 As shown, fasteners are passed through the inner cavity 11 so as to open the inner cavity 11 by removing the top cover 16 so as to assemble corresponding components in the inner cavity 11.

[0044] To facilitate the assembly of the light-transmitting plate 2, Figure 5 As shown, the front plate 12 is configured with a first opening 121 adapted to the light-transmitting plate 2 . The light-transmitting plate 2 can be fixed to the front plate 12 and cover the first opening 121 , which not only facilitates the assembly of the light-transmitting plate 2 but also ensures the sealing of the inner cavity 11 .

[0045] In one embodiment, the front plate 12 can be arranged vertically or tilted. Figure 3 As shown, in this embodiment, the front plate 12 is arranged in a vertically inclined manner to further reduce wind resistance. Preferably, the bottom plate 15 can be arranged horizontally, and the side plates 13 can be arranged vertically.

[0046] like Figure 3As shown, in this embodiment, a guide plate 18 for guiding the airflow to the connecting frame 4 (described below) is further provided between the front plate 12 and the bottom plate 15. The guide plate 18 is arranged obliquely, as shown in FIG. Figure 3 As shown, the inclination direction of the front plate 12 is the same as that of the guide plate 18, so as to guide the airflow to flow toward the bottom of the shell 1. During actual operation, the guide plate 18 can play the role of guiding and diverting the air, thereby effectively reducing the wind resistance.

[0047] In one embodiment, since a relatively closed inner cavity 11 is formed in the housing 1, and in actual use, the components installed in the inner cavity 11, such as the circuit board 5 and the camera components, generate heat, it is necessary to dissipate heat for the housing 1. Therefore, in this embodiment, the outer surface of the housing 1 is further provided with a plurality of heat dissipation fins 3. Figure 1 and 3 As shown, the heat dissipation area of ​​the housing 1 is effectively increased, thereby achieving a better heat dissipation effect, effectively preventing the temperature in the inner cavity 11 from being too high, and ensuring stable and long-term operation of the equipment.

[0048] In one embodiment, the heat dissipation fins 3 can be constructed on the front plate 12, the side plate 13, the top cover 16 or the rear plate 14. In order to achieve a better heat dissipation effect, in this embodiment, a windward surface 161 that is constructed to bulge upward and face the front end is provided on the top cover 16. Figure 1 and 4 As shown, heat dissipation fins 3 are constructed in the windward surface 161 .

[0049] In this way, on the one hand, during the operation of the locomotive, the airflow passes through the windward surface 161 at high speed and takes away the heat on the cooling fins 3, thereby achieving a better heat dissipation effect; on the other hand, the windward surface 161 can play a role in guiding the flow, thereby improving the flow state and distribution of the airflow on the top of the shell 1.

[0050] In one embodiment, the length direction of the heat dissipation fins 3 may be preferably consistent with the direction from the front end to the rear end of the housing 1. Figure 1 and 4 As shown, the airflow can flow more smoothly through the gap between the two heat dissipation fins 3, which is beneficial to further improve the heat dissipation efficiency.

[0051] In one embodiment, the top cover 16 is further provided with a leeward surface 163 connected to the windward surface 161, and side edge surfaces 162 arranged on both sides of the windward surface 161 and the leeward surface 163. Figure 1 and 4As shown, the side edge surface 162 and the leeward surface 163 are both arranged to be inclined in the vertical direction, so that the top of the shell 1 is more streamlined, which is beneficial to reducing wind resistance and stabilizing airflow.

[0052] Preferably, the side edge surface 162 can be preferably constructed as a triangular structure, and the windward surface 161 and the leeward surface 163 can be constructed as a trapezoidal structure, such as Figure 3 and Figure 4 As shown, it is also beneficial for the shell 1 to have a more beautiful shape.

[0053] In one embodiment of the present invention, in order to further improve the heat dissipation effect, corresponding heat dissipation fins 3 may also be constructed on the rear plate 14 to further increase the heat dissipation area. Figure 1 and Figure 3 As shown, the rear plate 14 may also be arranged to be inclined in the vertical direction so as to make full use of the tail gas and achieve a better heat dissipation effect.

[0054] Preferably, in order to facilitate the formation of heat dissipation fins 3 at the rear of the housing 1, the housing 1 further includes a rear cover 17. Figure 3 and Figure 8 As shown, the rear plate 14 is configured with a second opening 141 communicating with the inner cavity 11, the rear cover 17 is mounted on the rear plate 14 and closes the second opening 141, and the outer surface of the rear cover 17 is configured with heat dissipation fins 3, as shown in FIG. Figure 3 and Figure 8 As shown, the rear cover 17 may preferably adopt a plate-shaped structure, so that during implementation, the heat dissipation fins 3 can be processed on the rear cover 17 alone, which is very convenient.

[0055] According to the utility model, the vehicle-mounted observation device 100 further includes a connecting frame 4 located below the housing 1. Figure 1 and 3 As shown, the housing 1 can be detachably mounted on the upper end of the connecting frame 4 by means of fasteners such as bolts or screws, and the lower end of the connecting frame 4 is constructed with a flange plate, etc., so as to be connected to the locomotive.

[0056] In one implementation, the connecting frame 4 can be a frame with adjustable pitch angle in the prior art, so that the pitch angle of the camera device in the housing 1 can be conveniently adjusted during assembly. Preferably, in order to reduce wind resistance, a plurality of guide holes 41 can be constructed on the connecting frame 4, and the guide holes 41 are arranged from the front end of the housing 1 to the rear end of the housing 1, such as Figure 1 and 3 As shown, it can not only reduce wind resistance, but also reduce weight.

[0057] According to the utility model, the vehicle-mounted observation device 100 further includes a circuit board 5 and at least one camera device. Among them, each camera device is installed in the inner cavity 11 and corresponds to the light-transmitting plate 2 respectively. Each camera device is connected to the circuit board 5 respectively. The circuit board 5 is arranged in the inner cavity 11 and is mainly used for processing data and communicating with the outside world.

[0058] Preferably, the number of imaging devices arranged in the housing 1 can be determined according to actual needs, and can be one, two, three, four, etc.

[0059] In one implementation, the rear plate 14 or the rear cover 17 is also configured with a wiring hole 171, such as Figure 8 As shown, so as to perform wiring operation during assembly. Preferably, the imaging device can be an image acquisition device such as a video camera or a camera. Preferably, the circuit board 5 can adopt the circuit board 5 commonly used in the existing vehicle-mounted observation device, which will not be repeated here.

[0060] Example 2

[0061] In the present utility model, in order to solve the problem of defogging on the light-transmitting plate 2, the main difference between this embodiment 2 and the above-mentioned embodiment 1 is that in the vehicle-mounted observation device 100 provided in this embodiment, a defogger mechanism for defogging the light-transmitting plate 2 is also provided in the inner cavity 11.

[0062] According to the present invention, the demisting mechanism includes a fan (not shown) and a demisting member 6 disposed at the bottom end of the front plate 12. The demisting member 6 includes a pair of symmetrically arranged first demisting members 601 and a second demisting member 602 disposed between the two first demisting members 601.

[0063] Preferably, if Figure 5 and Figure 7 As shown, the first defogger 601 is configured as a special-shaped structure, that is, a roughly L-shaped structure. The first defogger 601 includes an air inlet 61 connected to the fan, and at least one first air outlet 621 facing the inner surface of the light-transmitting plate 2. In the present utility model, the number of the first air outlets 621 can be determined according to actual needs.

[0064] Preferably, if Figure 5 As shown, the second demister 602 is configured as a strip structure. The second demister 602 includes at least one second air outlet 622 facing the inner surface of the light-transmitting plate 2. In the present invention, the number of the second air outlets 622 can be determined according to actual needs.

[0065] In other embodiments, the defogger component 6 can be installed on the bottom plate 15 and / or the front plate 12 and / or the side plate 13 of the shell 1, and the air outlets (the first air outlet 621 and the second air outlet 622) are located at positions that adapt to the inner surface of the light-transmitting plate 2.

[0066] In one embodiment, the fan structure has an inlet and an outlet, and the fan is arranged in the inner cavity 11. For example, the fan can be installed on the bottom plate 15. The inlet of the fan is connected to the inner cavity 11, and the outlet of the fan is connected to the air inlet 61 of the first defogger 601, so as to guide the air at the inlet to continuously enter the defogger component 6 and be discharged through the first air outlet 621 of the first defogger 601 and the second air outlet 622 of the second defogger 602.

[0067] In the present invention, the fan may be an axial flow fan or a vortex fan commonly used in the prior art. Preferably, the fan may be connected to the circuit board 5 so that the circuit board 5 can be used to control the start and stop of the fan.

[0068] In the present invention, the fan is arranged in the inner cavity 11, and the inlet is connected to the inner cavity 11, and the outlet is connected to the air inlet 61 of the first defogger 601. Therefore, the fan can continuously provide the defogger 6 with the wind required for defogger, and the wind discharged from the air outlet (the first air outlet 621 and the second air outlet 622) acts on the inner surface of the light-transmitting plate 2, which can accelerate the air flow at the inner surface of the light-transmitting plate 2 and take away the fog, thereby achieving the purpose of defogger.

[0069] In addition, during actual use, the inner cavity 11 in the shell 1 is relatively closed, and the heat generated by the devices in the inner cavity 11 will cause the internal gas to rise steadily. By connecting the inlet of the fan with the inner cavity 11, the heat generated by the devices can be directed to the inner surface of the light-transmitting plate 2 by the fan, thereby achieving the purpose of heating the inner surface of the light-transmitting plate 2, thereby effectively removing the fog on the inner surface and ensuring that the internal camera device can always clearly capture external images or pictures through the light-transmitting plate 2.

[0070] In the present invention, the shape of the defogger component 6 can be determined according to actual needs, and the number of the defogger components 6 can also be determined according to actual needs.

[0071] Preferably, when two first demisters 601 and one second demister 602 are configured, Figure 5 and Figure 7 As shown, a connection port 63 is provided at the side ends of the first defogger 601 and the second defogger 602. Accordingly, the first defogger 601 and the second defogger 602 are connected to each other through the connection port 63.

[0072] Preferably, when only two first defogger elements 601 are configured, a connection port 63 is provided at the side ends of the first defogger element 601 and the second defogger element 602. Accordingly, the two first defogger elements 601 are connected to each other through the connection port 63.

[0073] It is easy to understand that during assembly, the connection can be achieved by simply plugging the connection port 63 of the first defogger 601 or the connection port 63 of the second defogger 602 into place, which is very convenient.

[0074] In one embodiment, a mounting position for installing a circuit board 5 is also provided in the inner cavity 11. Since the circuit board 5 generates a large amount of heat, the inlet of the fan can be preferentially set at the corresponding mounting position, so as to obtain higher temperature gas from the circuit board 5 at the mounting position, and guide the higher temperature gas to the inner surface of the light-transmitting plate 2, thereby achieving a better defog effect.

[0075] Preferably, the mounting position can be constructed on the rear plate 14 or the rear cover 17, such as Figure 8 As shown, not only can the circuit board 5 be installed on the rear plate 14 or the rear cover 17 away from the light-transmitting plate 2, but also the heat dissipation fins 3 on the rear plate 14 or the rear cover 17 can be used to achieve a better heat dissipation effect.

[0076] Preferably, the mounting position may include a threaded hole 72 and / or a through hole 84 , etc., so as to fix and constrain the circuit board 5 .

[0077] In one embodiment, the camera device may be installed on the bottom plate 15 of the housing 1 , or may be installed on a shelf, and the shelf may be fixed to the bottom plate 15 of the housing 1 .

[0078] Example 3

[0079] In the present utility model, in order to solve the problem of facilitating the rapid assembly of the camera device, the main difference between this embodiment and the above-mentioned embodiment is that in the vehicle-mounted observation device 100 provided in this embodiment, at least two spaced-apart supports 7 and a plurality of brackets 8 are further provided in the housing 1, such as Figure 5 , Figure 6 and Figure 8 As shown, the opposite sides of the support 7 are respectively configured with slots 71 , and the two slots 71 correspond to each other.

[0080] like Figure 5 , Figure 6 and Figure 8 As shown, a slot 71 is provided on the support 7. Preferably, the vehicle-mounted observation device 100 includes a mounting plate 81 adapted to the slot 71, and a baffle 83 connected to one end of the mounting plate 81. Preferably, as Figure 5 and Figure 8The bracket 8 shown may preferably adopt an L-shaped structure or a structure similar to an L-shaped structure.

[0081] In one embodiment, the mounting plate 81 is configured with a mounting portion adapted to the camera device. The mounting portion may be a mounting hole 82, an existing snap-fit ​​structure, etc. The mounting hole 82 may be a through hole 84 or a threaded hole 72. Preferably, the mounting hole 82 is a through hole 84, so that the camera device can be mounted on the mounting plate 81 using a fastener such as a bolt pair adapted to the through hole 84.

[0082] Preferably, the mounting plate 81 is inserted into the slot 71, such as Figure 5 , Figure 6 and Figure 8 As shown, the baffle plate 83 is detachably mounted on the end of the support 7. In this way, during assembly, the camera device can be first mounted on the mounting plate 81, and then the mounting plate 81 is inserted into the slot 71, and finally the mounting plate 81 is locked at the end of the support 7. Not only is the operation more convenient and smooth, the assembly of the camera device can be completed quickly, but it is also easy to disassemble and replace, which is conducive to subsequent inspection and maintenance.

[0083] In the present invention, in order to realize the detachable connection between the baffle 83 and the support 7, there are many implementation methods in the prior art. As an example, Figure 5 , Figure 6 and Figure 8 As shown, the end of the support 7 is configured with a threaded hole 72, and the baffle 83 is configured with a through hole 84 adapted to the threaded hole 72, so that the baffle 83 can be threadedly connected to the threaded hole 72 by a fastener adapted to the threaded hole 72 and the through hole 84, thereby achieving the purpose of fixing to the support 7.

[0084] It is easy to understand that the slot 71 only passes through one end of the support 7 so that the insertion depth of the mounting plate 81 can be controlled by using the slot 71 .

[0085] In the present invention, the number of the supports 7 can be adapted to the number of the camera devices to be installed. For example, when one camera device needs to be installed, only two supports 7 are required. When two camera devices need to be installed, three supports 7 are required. Figure 5 and Figure 8 As shown, when three camera assemblies need to be installed, four supports 7 need to be configured, and the four supports 7 are arranged in a row, and the demisting component 6 is located between the supports 7 and the light-transmitting plate 2.

[0086] Compared with the prior art, the advantages of the present invention are:

[0087] First, in this solution, by configuring a shell 1 and an inner cavity 11 arranged in the shell 1, the required devices can be installed in the inner cavity 11, which can effectively isolate and protect the internal devices; by configuring a light-transmitting plate 2 in the shell 1, the internal camera device can collect external images or pictures through the light-transmitting plate 2; by configuring a defogger mechanism inside the shell 1, the defogger mechanism can be used to remove the fog and water on the inner surface of the light-transmitting plate 2, thereby ensuring that the internal camera device can work normally.

[0088] Second, in this case, the fan is arranged in the inner cavity 11, and the inlet is connected to the inner cavity 11, and the outlet is connected to the air inlet 61 of the first defogger 601. Therefore, the fan can continuously provide the defogger 6 with the wind required for defogger, and the wind discharged from the air outlet (the first air outlet 621 and the second air outlet 622) acts on the inner surface of the light-transmitting plate 2, which can accelerate the air flow at the inner surface of the light-transmitting plate 2 and take away the fog, thereby achieving the purpose of defogger.

[0089] In addition, during actual use, the inner cavity 11 in the shell 1 is relatively closed, and the heat generated by the devices in the inner cavity 11 will cause the internal gas to rise steadily. By connecting the inlet of the fan with the inner cavity 11, the heat generated by the devices can be directed to the inner surface of the light-transmitting plate 2 by the fan, thereby achieving the purpose of heating the inner surface of the light-transmitting plate 2, thereby effectively removing the fog on the inner surface and ensuring that the internal camera device can always clearly capture external images or pictures through the light-transmitting plate 2.

[0090] Thirdly, the utility model can not only effectively defog, but also utilize the heat generated during its own use to improve the defog effect, ensuring that the internal camera device can always clearly capture external images or pictures through the light-transmitting plate, thereby ensuring that the device can operate stably and reliably.

[0091] In the description of the present utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
