Description

Technical Field

[0001] The present invention belongs to the technical field of traffic control equipment for road vehicles, and specifically relates to an intelligent traffic capture all-in-one machine. Background Art

[0002] The intelligent traffic capture integrated machine is an important part of the modern intelligent transportation system. It integrates a variety of advanced technologies for traffic monitoring and management. The intelligent traffic capture integrated machine can not only identify vehicles and license plates, but also detect a variety of violations, such as speeding, crossing the line, driving in the wrong direction, not wearing seat belts, making phone calls, etc.

[0003] The existing Chinese utility model patent with patent announcement number CN202189466U proposes an intelligent traffic capture integrated machine, which triggers the network alarm module through the CCD image sensor and takes pictures through the video information acquisition module, so that the storage capacity required by the system is small;

[0004] In the prior art, CCD image sensors, as trigger devices, need to be matched with other supporting equipment such as shutters, lenses, and memory to produce images. Cameras of video information acquisition modules also adopt the same working principle. Image acquisition devices such as CCD image sensors and cameras arrange shutters, lenses, and photosensitive sensors in sequence to form a long strip shape. During installation, bolts are usually set at one end of the lens of the camera to fix it to the shell, and the other positions are suspended. In this fixing method, in an environment with a large number of heavy-loaded vehicles such as national highways, the vibration of the shell is transmitted to the camera position. Since the camera is fixed at the front end and the other parts are suspended, the rear end of the camera shakes more greatly, causing cracks or even breaks in the connection. The large shake also affects the normal shooting function of the camera. In view of this, an intelligent traffic capture all-in-one machine is provided. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide an intelligent traffic capture all-in-one machine.

[0006] The technical solution adopted to solve the above technical problems is:

[0007] An intelligent traffic capture integrated machine comprises an adjustment frame and a probe, wherein the adjustment frame is used to install the probe, and the probe has a built-in laser component;

[0008] The probe includes a camera, the outer side of the camera is wrapped with a protective shell, the laser assembly is arranged at one end of the protective shell where the camera is installed, the protective shell is provided with a window for light to pass through, the camera is provided with a mounting frame along the axial direction, and the mounting frame penetrates the side wall of the protective shell and is exposed to the air;

[0009] The laser assembly includes two laser transceivers, and there is an angle between the light output paths of the two laser transceivers. A connecting rod is arranged between the two laser transceivers, and the connecting rod is assembled and connected to the mounting frame.

[0010] Furthermore, the mounting frame includes an end plate, which is mounted on the camera shooting end, a fixed frame is mounted on the outer side of the end plate, the fixed frame is fixedly connected to the protective shell, a positioning seat cooperating with the laser transceiver is provided on the inner wall of the protective shell, a connecting frame is installed on the side of the end plate facing away from the camera shooting end, the connecting frame is connected to a side frame through a straight plate, and the side frame is embedded in the protective shell.

[0011] Through the above technical scheme, the end plate and the connecting frame are detachably connected by bolts, and after being assembled, a cage structure is formed to wrap the camera. The end plate and the fixed frame are plugged and fixed, and the side frame is embedded and connected with the protective shell to fix the two ends of the camera, and the end plate and the fixed frame are used to protect the camera lens from dust and water.

[0012] Furthermore, two straight plates are provided, and end sleeves are installed at one end of the two straight plates away from the straight plates, and the end sleeves are installed on the outside of the connecting frame. A hanging plate perpendicular to the straight plates is installed in the middle of the straight plates, and the end of the hanging plate is in direct contact with the side wall of the camera.

[0013] Through the above technical solution, the hanging plate is installed in the middle section of the straight plate, and the hanging plate is in direct contact with the outer walls around the camera, which improves the connection stability between the straight plate and the camera and reduces vibration, while performing efficient heat conduction.

[0014] Furthermore, two side frames are provided, the middle parts of the two side frames are bent and extended toward the camera, and fins are installed on the side of the side frame facing away from the camera.

[0015] Through the above technical solution, the heat of the straight plate and the hanging plate, as well as the heat absorbed by the air inside the protective shell, are transferred to the side frame position to contact the outside air for dissipation. The concave shape of the side frame increases the heat exchange contact area, and the concave shape of the side frame can increase the tightness of the joint with the protective shell.

[0016] Furthermore, the protective shell includes a bottom shell, a top cover is hingedly mounted on the top of the bottom shell, an outer edge is fixedly mounted on the top surface of the top cover, and a through opening is formed at the edge of the top cover which is bent away from the outer edge.

[0017] Through the above technical solution, the bottom shell and the top cover are movably connected, which makes the camera maintenance convenient.

[0020] Furthermore, an insertion rod is provided at one end of the connecting rod, a plug hole cooperating with the insertion rod is provided at the second end of the connecting rod, and a graduated groove is provided on the circumferential outer wall of one end where the connecting rod one and the connecting rod two are plugged into each other.

[0021] Through the above technical solution, the insertion rod and the insertion hole are interference fit and will not rotate when not subjected to external force. The scale groove can indicate the size of the angle. The scale groove improves the roughness of the contact surface with the pressure plate and is firmly installed.

[0023] Through the above technical solution, the laser transceiver can still be stably limited by the positioning seat no matter how the angle is adjusted. The single-sided opening of the connector is convenient for disassembly and assembly with the protrusion. The outer diameter of the protrusion changes and can only be connected in one direction, which prevents installation errors and simplifies the installation process.

[0024] Furthermore, the adjustment frame includes a middle shell, which is installed above the probe. The middle shell is provided with an opening facing the probe, and a fill light is embedded in the opening position. The light emitting direction of the fill light is parallel to the shooting direction of the probe.

[0025] Through the above technical solution, the middle shell places the fill light above the probe to avoid shining in front of the camera lens and affecting the clarity of the photo.

[0027] Through the above technical solution, the middle shell can rotate horizontally around the ball head, and the swing arm can adjust the pitch angle of the probe, which is convenient for adjusting the direction of the fill light and the probe at the same time without affecting the individual angle adjustment of the probe.

[0028] The beneficial effects of the present invention are as follows:

[0029] (1) The present invention adopts the design of the mounting frame, and a cage-type connecting frame and end plate are installed on the outside of the camera. The connecting frame is fixed to the side wall of the protective shell through a straight plate and a side frame, and the head and tail ends of the camera are fixed to reduce the shaking of the camera itself under a vibration environment. The mounting frame transfers the heat of the camera to the side frame position, and the concave side frame stably seals the internal space of the protective shell and can be in contact with the outside air for efficient heat dissipation;

[0030] (2) The present invention uses the laser assembly to emit light from two high-speed laser transceivers. During the debugging phase, the camera's shooting centerline position and upper limit position are displayed on the ground, which is convenient for adjusting the camera angle and shooting distance. During the use phase, the laser transceiver's light output angle is adjusted to identify the vehicle before the vehicle enters the camera's shooting range, providing a signal for waking up the dormant camera, reducing the camera's energy consumption, and extending the camera's use time.

[0031] (3) The present invention provides an adjustment frame, wherein the middle shell of the adjustment frame can be connected to the top frame and the probe, and provide an installation space for the fill light. The fill light and the probe are arranged separately, thereby reducing the influence of the brightness and heat of the fill light on the operation of the probe. The middle shell can adjust the directions of the probe and the fill light at the same time, and can adjust the angle of the probe separately, thereby ensuring clear capture while reducing the time that the fill light directly shines on the driver's eyes, thereby improving the safety of the fill light.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] like Figure 1 - Fig. 9 As shown, the present embodiment provides an intelligent traffic capture integrated machine, including an adjustment frame 1 and a probe 2. When capturing speeding or violation, the adjustment frame 1 is used to install the probe 2. The end of the adjustment frame 1 has a flange, through which a screw can be passed to fix the probe 2 on a gantry or other main frame. The probe 2 is connected to a power supply and a data processing device through a wire, and is used to capture and upload vehicle information on the lane. In order to control production costs and failure rates, the probe 2 adopts a camera 6 with a fixed focal length, and long-term operation can ensure normal functions. During installation and use, in order to ensure the clarity of the camera 2, it is necessary to pre-adjust the shooting angle and distance. In order to improve the debugging efficiency, a laser component 4 is built in the probe 2. During debugging, the function of the laser component 4 to emit a laser beam can be used to display the facing position of the probe 2 on the ground, so as to facilitate the debugging efficiency of the shooting angle and distance. When in use, the ranging function of the laser component 4 can be used as a wake-up signal. When a moving object on the road is detected to enter the shooting range, the probe 2 is awakened to take pictures. The adjustment and working process are more intelligent, effectively reducing the energy consumption of the equipment.

[0044] It should be noted that the laser component 4 uses a high-speed laser ranging sensor model ZDS08. Without a reflector, the maximum measurable distance is 250 meters, which can completely cover the shooting distance required by the probe 2. At the same time, the vehicle paint surface is smooth and has a strong ability to reflect light compared to the asphalt ground. The laser component 4 can smoothly receive the reflected light to ensure the normal operation of the wake-up function.

[0045] Regarding probe 2, in order to achieve stable photography, refer to Figure 2 and Figure 4 The probe 2 includes a camera 6. The camera 6 is a fixed-focus camera 6 without a focus adjustment mechanism. The focusing work is completed in advance during installation. The camera 6 only has a photo-taking function, and the failure rate is lower during operation. Among them, the outer side of the camera 6 is wrapped with a protective shell, which wraps the camera 6 for waterproof and dustproof protection, further improving the working stability of the camera 6. At the same time, the laser component 4 is arranged at one end of the protective shell where the camera 6 is installed to ensure that the photo-taking direction of the camera 6 is consistent with the light-emitting direction of the laser component 4. In addition, the protective shell is provided with a window for light to pass through. High-strength glass is installed at the window position, and a motor-driven cleaner is used to perform regular wiper and dust removal to ensure clear photos. Under the premise of ensuring sealing, The camera 6 is provided with a mounting bracket 5 along the axial direction, and the length of the mounting bracket 5 is consistent with the front-to-back length of the camera 6, so that the entire camera 6 can be fixedly connected. Compared with the installation method of only fixing the shooting end, the influence of vibration on the installation stability of the camera 6 can be reduced, and the self-vibration of the camera 6 can be reduced, so as to ensure the stable operation of the camera 6 in the use scene with large vibration. The mounting bracket 5 penetrates the side wall of the protective shell and is exposed to the air. The mounting bracket 5 is made of aluminum or alloy, so that the heat can be transferred through the mounting bracket 5 while ensuring the structural strength, so as to realize the heat dissipation function of the camera 6 and ensure the temperature stability of the camera 6 under long-term operation.

[0046] For laser module 4, refer to Figure 1 and Figure 4 The laser assembly 4 includes two laser transceivers 41. There is an angle between the light paths of the two laser transceivers 41. One of the laser transceivers 41 is parallel to the shooting direction of the camera 6, which can indicate the middle shooting position of the camera 6, so as to accurately indicate the shooting position during installation. The other laser transceiver 41 has a smaller inclination angle, and the light generated can irradiate a position farther from the installation position of the camera 6, so as to trigger the camera 6 to start working before the moving object enters the shooting range, so as to avoid the vehicle passing through the shooting range before the camera 6 captures the image. The laser transceiver 41 parallel to the shooting direction of the camera 6 can be awakened for a second time, and the redundant design ensures the smooth shooting. At the same time, referring to Figure 7A connecting rod is provided between the laser transceivers 41. During production, the connecting rod installs the two laser transceivers 41 together, so that the connecting rod can be assembled and connected with the mounting frame 5, and the installation is faster.

[0047] In a further embodiment, in order to achieve stable installation of the camera 6, refer to Figure 4 and Figure 5 The mounting frame 5 includes an end plate 56, which is sleeved and installed on the shooting end of the camera 6. The hole in the middle of the end plate 56 will not affect the shooting. A fixed frame 51 is sleeved on the outer side of the end plate 56. The end plate 56 and the fixed frame 51 are slidably plugged and combined and fixed by bolts. Among them, the fixed frame 51 is fixedly connected to the protective shell, and the front end of the camera 6 can be fixed. A connecting frame 53 is installed on the side of the end plate 56 facing away from the shooting end of the camera 6. The rear end of the connecting frame 53 is fixed to the rear end of the camera 6, and it has two support rods extending front and back. During installation, the bolts penetrate the end plate 56 and the front end of the support rods of the connecting frame 53 and are detachably connected. After assembly, a cage structure is formed to wrap the camera 6, and the connecting frame 53 is connected to the side frame 52 through the straight plate 54. The side frame 52 is embedded in the protective shell and installed, so that the front and rear ends of the camera 6 can be fixed to the protective shell, so as to avoid the vibration of the rear end of the camera 6 when only the front end of the camera 6 is fixed, thereby improving the installation stability of the camera 6 and the shooting effect.

[0048] In a further embodiment, referring to Figure 4 - Figure 6 , there are two straight plates 54, which are arranged on the upper and lower sides of the camera 6, wherein the two straight plates 54 are installed with end sleeves 59 at one end away from the straight plates 54. When combined, the end sleeves 59 are sleeved and installed on the outside of the connecting frame 53, and the direct sleeve installation is fast. A hanging plate 58 perpendicular to the straight plate 54 is installed in the middle of the straight plate 54, and the hanging plate 58 is connected to the protruding position of the outer wall of the camera 6. The hanging plate 58 reinforces the overhead position of the middle section of the straight plate 54, reduces the vibration of the straight plate 54 under a vibration environment, and improves the installation tightness. In addition, the straight plate 54 is fixed to different positions of the camera 6 through the end sleeves 59 and the hanging plate 58, which improves the firmness of the installation. At the same time, the end of the hanging plate 58 is in direct contact with the side wall of the camera 6, and the hanging plate 58 is in direct contact with the outer wall around the camera 6, and the end sleeve 59 is sleeved and connected with the connecting frame 53 to increase the effective contact area for efficient heat conduction.

[0049] It should be noted that, refer to Figure 4 The end plate 56 and the fixed frame 51 are slidably plugged in to seal the lens position of the camera 6. A sealing ring is installed between the edge of the end plate 56 and the inner wall of the fixed frame 51 to prevent the air in the protective shell from entering the sealing position of the camera 6 lens, thereby providing further dust and moisture protection.

[0050] In a further embodiment, referring to Figure 5 and Figure 6, there are two side frames 52, which are symmetrically arranged on both sides of the camera 6, so that the camera 6 can be tightened and fixed in the center, and the installation is more secure. At the same time, the middle parts of the two side frames 52 are bent and extended toward the camera 6. The concave side of the side frame 52 can increase the heat exchange contact area. Among them, the heat of the camera 6 absorbed by the straight plate 54 and the hanging plate 58 will be transferred to the side frame 52. The heat of the camera 6 will also be transferred to the air inside the protective shell at the same time, and then transferred to the side frame 52 for dissipation. Among them, the side frame 52 is equipped with a fin 55 on the side facing away from the camera 6, which can further The heat dissipation area is increased by the concave shape of the side frame 52. While the two side frames 52 are tightened toward each other to fix the camera 6, the fins 55 can support the side frame 52 to ensure the structural stability of the side frame 52. The edge of the side frame 52 is in an inclined outward state greater than ninety degrees, that is, the size of the side frame 52 located on the outside of the protective shell will gradually increase, and the size of the opening position will reach the maximum. When the side frame 52 contacts the side wall of the opening of the protective shell, as the two side frames 52 are tightened toward the inside of the protective shell, the side frame 52 can be tightly pressed against the inner wall of the opening of the protective shell, thereby improving the tightness of the seam with the protective shell.

[0051] In a further embodiment, referring to Figure 2 and Figure 4 The protective shell includes a bottom shell 21, and a top cover 22 is hingedly installed on the top of the bottom shell 21. The front end of the bottom shell 21 is movably connected to the front end of the top cover 22 by a hinge, and the rear end of the bottom shell 21 is connected to the rear end of the top cover 22 by bolts. After removing the bolts, the top cover 22 can be lifted forward to facilitate maintenance and replacement of the internal camera 6 and other structures. An outer edge 23 is fixedly installed on the top surface of the top cover 22. The front and rear ends of the outer edge 23 exceed the length of the top cover 22 and are connected to each other by spring screws. In the scene of heavy rain and hail, the outer edge 23 is buffered and partitioned, which can buffer the impact on the protective shell and reduce The damage caused by vibration can be prevented, and the clarity of the photo can be ensured. At this time, the edge of the top cover 22 is bent away from the outer edge 23 to form a through hole 24. The top cover 22 adopts a good thermal conductor, such as an aluminum sheet. Heat can be dissipated through the top cover 22. At the same time, with the protection of the outer edge 23, the top cover 22 adopts a thinner thickness to still ensure the protection effect. After installation, in order to take pictures of vehicles on the ground, the front end of the protective shell will tilt downward. When the wind passes through the front and rear directions, the outer edge 23 can allow more airflow to pass through the through hole 24, thereby supplementing the heat dissipation of the space inside the protective shell.

[0052] In a further embodiment, referring to Figure 7 and Figure 8The mounting frame 5 is provided with a card slot 57 at the bottom of the camera 6. The card slot 57 opens backwards, and the connecting rod can be directly inserted forward, which is convenient for installation. The connecting rod is installed in the card slot 57. The connecting rod includes a connecting rod 1 42 and a connecting rod 2 43. The connecting rod 1 42 and the connecting rod 2 43 are slidably plugged in. The card slot 57 is located at the plug-in position of the connecting rod 1 42 and the connecting rod 2 43. A pressure plate 45 is installed. When installing two laser transceivers 41, the pressure plate 45 is used to press them to improve the installation efficiency. At the same time, the split connecting rod 1 42 and the connecting rod 2 43 rotate with each other, and the angle between the two laser transceivers 41 can be adjusted. In the scene of high-speed driving, the angle of the laser transceiver 41 can be adjusted to detect the entry of the vehicle earlier and To wake up the camera 6, after the installation is completed, the laser transceiver 41 originally irradiated in the middle of the shooting range of the camera 6 can be adjusted so that it can also detect the entry of the vehicle before the vehicle enters the shooting range of the camera 6, and provide another wake-up signal to prevent the wake-up failure caused by damage to individual laser transceivers 41 and failure of signal transmission, thereby further ensuring the stable operation of the equipment for a long time. In addition, the speed of the vehicle can be measured by using two laser transceivers 41 to respectively detect the moment when the vehicle passes and the distance between the shooting positions of the two laser transceivers 41. Among them, the two laser transceivers 41 can adopt models that transmit and receive light of different wavelengths to avoid mutual interference and ensure the smooth progress of speed measurement.

[0053] In a further embodiment, referring to Fig. 9 A plug rod 47 is provided at the end of the connecting rod 1 42, and a socket 49 cooperating with the plug rod 47 is provided at the end of the connecting rod 2 43. During production, the plug rod 47 and the socket 49 are interference fit and do not rotate actively, which can ensure the stability of the relative position and the stability of the relative position of the two laser transceivers 41 after being installed in the card slot 57. At the same time, a scale groove 48 is provided on the circumferential outer wall of one end of the connecting rod 1 42 and the connecting rod 2 43 where they are plugged into each other. During production, the scale groove 48 can indicate the size of the included angle. Each time a product with a different shooting range or a different wake-up time is produced, the employees can directly rotate to the corresponding angle through employee training or providing a production manual, which is convenient for production and debugging. After the angle is adjusted, during installation, the scale groove 48 serves as an indicator, because grooves are formed on the connecting rod 1 42 and the connecting rod 2 43, which can improve the roughness of the contact surface with the pressure plate 45, ensure the firm installation after crimping, and prevent the angle change of the laser transceiver 41 caused by vibration.

[0054] In a further embodiment, referring to Figure 7, connecting rod 1 42 and connecting rod 2 43 are installed with a protrusion 46 at one end away from each other, and the laser transceiver 41 adopts a cylindrical shape. No matter how the angle of the laser transceiver 41 is adjusted, a truncated cone is provided at the end face of the laser transceiver 41, and a positioning seat 25 cooperating with the laser transceiver 41 is installed on the inner wall of the protective shell, which can still be stably limited by the positioning seat 25. A connecting piece 44 is installed at the center of the end face of the laser transceiver 41. The connecting piece 44 is a cylindrical shape with a single-side opening, and a screw hole is provided along the radial direction to install the clamping bolt. The protrusion 46 is a rectangular structure, and the outer diameter of the protrusion 46 varies. After being clamped with the connecting piece 44, after the installation is completed, the clamping screw is tightened to clamp the connecting piece 44 and the protrusion 46, and relative rotation or slippage will not occur. In addition, the opening direction of the connecting piece 44 is consistent with the light-emitting direction of the laser transceiver 41. This fool-proof design can ensure that the two laser transceivers 41 are in the same direction after installation, prevent installation errors and simplify the installation process.

[0055] In a further embodiment, referring to Figure 1 and Figure 2 The adjustment frame 1 includes a middle shell 12, which is installed above the probe 2. The middle shell 12 is provided with an opening facing the direction of the probe 2, and a fill light 3 is embedded in the opening position. The middle shell 12 places the fill light 3 above the probe 2 to avoid emitting light in front of the camera 6 and affecting the clarity of the photo. The fill light 3 and the probe 2 are separated during installation to prevent the high temperature of the fill light 3 working for a long time from affecting the stable operation of the probe 2. At the same time, the light emitting direction of the fill light 3 is parallel to the shooting direction of the probe 2, so fill light can be provided when taking photos.

[0056] In a further embodiment, referring to Figure 1 and Figure 3 The adjustment frame 1 also includes a top frame 11, a ball head 14 is fixedly installed at the end of the top frame 11, and two middle shells 12 are symmetrically arranged with the diameter of the ball head 14 as the normal line. The ends of the two middle shells 12 are provided with hemispherical grooves that match the ball head 14. The two middle shells 12 can be mutually engaged and fixed to each other by bolts. After the two middle shells 12 are combined, they can be horizontally rotated around the ball head 14 to horizontally adjust the shooting direction and the fill light direction. At the same time, a swing arm 13 is installed between the middle shell 12 and the probe 2 by bolts. The swing arm 13 is divided into two sections, and the middle is connected by bolts to bend by loosening the bolts. The swing arm 13 can adjust the pitch angle of the probe 2 independently. When the angle of the probe 2 is adjusted to face the direction of the oncoming vehicle, the fill light 3 can be tilted downward at a greater angle to illuminate the ground at a distance in front of the vehicle, and the scattering of light by the ground can be used to play a fill light role. When the vehicle passes through the direct illumination position of the fill light 3, the roof can block part of the light of the fill light 3, reducing the time that the fill light 3 can directly illuminate the driver's eyes. By installing and debugging the angle between the probe 2 and the fill light 3 on site, the direct illumination of the driver's eyes can be reduced, thereby improving safety.

[0057] The working principle of this embodiment is as follows:

[0058] During production, the two laser transceivers 41 are installed in the protective shell at an acute angle. The angle between the two laser transceivers 41 can be adjusted by the relative rotation of the connecting rod 1 42 and the connecting rod 2 43, and the scale groove 48 is used to assist in determining the angle. During installation and use, the scale groove 48 is used to improve the installation firmness of the laser transceiver 41;

[0059] During debugging, the probe 2 is fixed on the gantry on the roadside by using the adjustment frame 1, and the light-emitting characteristics of the two laser transceivers 41 can be used to illuminate the shooting centerline position and upper limit position of the probe 2 on the ground, so as to quickly determine the shooting range of the camera 6 with a fixed focal length, and provide a reference for adjusting the shooting distance and angle of the probe 2;

[0060] After installation, the top cover 22 can be opened, and the angles of the two laser transceivers 41 can be adjusted by the relative rotation of the connecting rod 1 42 and the connecting rod 2 43. The distance measurement function of the two laser transceivers 41 can be used to detect the entry of the vehicle before the vehicle enters the shooting range of the probe 2, and the camera 6 can be awakened to take pictures. When no vehicle passes by, the camera 6 can be on standby to avoid the camera 6 being in a powered-on working state all the time, saving energy and ensuring the long-term service life of the camera 6. At the same time, the angle difference of the two laser transceivers 41 can be used to capture the passing information of the same vehicle in succession to perform speed measurement operations;

[0061] When in use, an outer edge 23 is movably installed on the top of the top cover 22. The outer edge 23 can reduce the impact, protect the stability of the camera 6 and reduce the shaking. At the same time, the camera 6 is fixed in the protective shell through the mounting bracket 5, and the front and rear ends of the camera 6 are connected to the side wall of the protective shell by the straight plate 54. Compared with fixing the front end of the camera 6 alone, the stability of the installation is improved and the shaking amplitude when a truck passes by is reduced. In addition, the mounting bracket 5 extends to the outside of the protective shell and uses its own concave shape to efficiently contact and exchange heat with the external air. The camera 6 can be efficiently cooled and cooled under the premise of sealing, ensuring the temperature stability of the camera 6 during long-term operation.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
