Therefore, in order to reduce the occurrence of traffic accidents, it is very necessary to frequently remind drivers to pay attention to their driving speed.

[0003] When drivers suddenly enter areas where they need to slow down, they continue to drive at high speed because they do not notice the deceleration signs in time or there are no deceleration signs, resulting in violations. To address these problems, the current technical means adopted are to detect the speed of passing vehicles through speed feedback meters installed on the road. In this way, drivers can clearly see their own speed values, thereby reducing many unnecessary violations and achieving certain results.

[0004] However, most existing vehicle speed feedback instruments are of an integrated box structure, which is inconvenient to assemble, difficult to disassemble, inconvenient for subsequent maintenance, and has low maintenance efficiency. Utility Model Content

[0033] When drivers suddenly enter areas where deceleration is required, they fail to notice the deceleration signs or continue driving at high speeds, resulting in traffic violations. Currently, a technical solution is to use speed feedback devices installed on the road to detect the speed of passing vehicles. This allows drivers to clearly see their own speed values, thus reducing many unnecessary violations and achieving certain results. However, existing speed feedback devices are mostly integrated box structures, which have technical problems such as inconvenient assembly and disassembly, difficulty in later maintenance, and low maintenance efficiency.

[0034] To address the above technical issues, embodiments of the present application provide a radar speed measuring device. The device utilizes a separate housing and a cover plate, movably connecting the housing and the cover plate so that the cover plate can rotate relative to the housing. Thus, when the radar speed measuring device is in normal operation, the cover plate covers the housing, preventing dust and rain from entering the housing and damaging the components within. When the radar speed measuring device malfunctions, the cover plate moves away from the housing to expose the components within the housing, facilitating fault locating and repair by maintenance personnel. By electrically connecting a radar speed meter and an electronic display to a controller, signals detected by the radar speed meter are transmitted to the controller. The controller then processes and analyzes the signals detected by the radar speed meter to obtain a vehicle speed value. The processed speed value is displayed on the electronic display, allowing passing drivers to view the real-time speed, thereby providing a warning and preventing violations such as drivers entering areas where speed reduction is required but failing to promptly notice speed reduction signs and continuing to drive at high speeds. At the same time, by arranging the controller in the accommodating cavity and arranging the radar speed meter and the electronic display on the cover plate, the problem of the wiring harness being entangled due to the lengthy wiring harness is avoided, and the system has the advantages of easy assembly.

[0035] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] In the examples of this application, reference Figures 1 to 4 As shown, the radar speed measuring device 100 includes a housing 110 and a radar speed measuring component 120 , and the radar speed measuring component 120 is disposed on the housing 110 .

[0037] In the embodiment of the present application, the material of the shell 110 is not further limited. For example, the material of the shell 110 is aluminum alloy or stainless steel, which has strong corrosion resistance, can prevent damage to the shell 110 caused by rain erosion, and has a long service life.

[0038] In the examples of this application, reference Figure 1 As shown, the shell 110 includes a shell body 111 and a cover plate 112, wherein a waterproof rubber strip is arranged between the shell body 111 and the cover plate 112, and the surfaces of the shell body 111 and the cover plate 112 are coated with a protective layer to achieve an IP67 protection level, which can prevent outdoor rainwater, dust, etc. from invading the shell 110, thereby causing damage to the radar speed measurement component 120 inside the shell 110.

[0039] Continue to refer Figure 1 As shown, the shell body 111 has a accommodating cavity 113, and the accommodating cavity 113 is provided with an opening connected to the accommodating cavity 113 along a first direction, wherein the first direction is toward the direction of the vehicle. The purpose of such a setting is to facilitate the monitoring and management of the vehicle's driving speed and ensure the safety and order of road traffic.

[0040] In this embodiment, the cover plate 112 is provided at the opening and is movably connected to the housing body 111. When the radar speed measuring device 100 is working normally, the housing 110 is in a locked state. At this time, the cover plate 112 and the housing body 111 fit tightly together to prevent dust and other impurities from entering the housing 110. Figure 2 When the radar speed measuring device 100 fails, the cover 112 can be rotated relative to the shell body 111 to open the shell 110. At this time, there is an angle between the cover 112 and the shell body 111, and maintenance personnel can repair the components inside the shell 110.

[0041] The purpose of this arrangement is that, compared with the traditional integrated radar speed measuring device, the present application can allow the cover 112 and the shell body 111 to open and close freely. When the radar speed measuring device 100 encounters a fault, there is no need to remove the entire radar speed measuring device 100 from the support for maintenance, debugging, etc., which effectively improves the work efficiency of the maintenance personnel.

[0042] Continue to refer Figure 1 As shown, the radar speed measurement component 120 includes a radar speed meter 121, a controller 122 and an electronic display 123. The radar speed meter 121 and the electronic display 123 are both electrically connected to the controller 122, and the controller 122 is disposed in the accommodating cavity 113. The radar speed meter 121 and the electronic display 123 are disposed on the cover plate 112.

[0043] The radar speed gun 121 transmits electromagnetic waves toward the vehicle. When it encounters a vehicle, the electromagnetic waves are reflected back, and the radar speed gun 121 receives the electromagnetic wave signal. Based on the transmitted and received electromagnetic wave signals and in combination with relevant formulas, the radar speed gun 121 calculates the vehicle's speed, which can be displayed on the electronic display 123. Specifically, in this embodiment, the frequency of the radar speed gun 121 is 24 GHz.

[0044] In this embodiment, reference Figure 2 As shown, the electronic display 123 includes a maximum speed display screen 124 and a real-time speed display screen 125. The maximum speed display screen 124 is arranged above the real-time speed display screen 125. The maximum speed display screen 124 and the real-time speed display screen 125 can be displayed in different colors to facilitate the driver to identify whether he is speeding and serve as a warning.

[0045] As an optional implementation, in this embodiment, the maximum speed display screen 124 and the real-time speed display screen 125 are LED display screens with high brightness and visibility.

[0046] Specifically, the maximum speed display screen 124 and the real-time speed display screen 125 are fixedly connected to the outer surface of the housing 110 by waterproof glue or rivets.

[0047] In one possible implementation, referring to Figure 1 and Figure 4 As shown, the housing body 111 has a plurality of hinges 114, which are spaced apart along the second direction. The first end of the cover 112 is hingedly connected to the housing body 111 via the hinges 114, so that the cover 112 can be opened and closed relative to the housing body 111. The second direction is the extension direction of the housing body 111.

[0048] In this embodiment, the type of hinge 114 is not further limited. For example, the hinge 114 can be a spring hinge, a damping hinge, a common hinge, etc., as long as it can enable the cover 112 to rotate relative to the housing body 111. The hinge 114 is connected to the housing body 111 and the cover 112 by threads.

[0049] refer to Figure 4 As shown, in this embodiment, there are two hinges 114, and the two hinges 114 are respectively arranged at both ends of the shell body 111 along its extension direction. The purpose of such arrangement is to have higher strength and stronger connection stability.

[0050] The hinge 114 is also provided with a limiter (not shown) for fixing the position of the cover 112 to prevent the cover 112 from swinging back and forth during maintenance, thereby hindering the maintenance worker's operation. Specifically, the opening angle of the cover 112 can be adjusted according to actual conditions.

[0051] In another optional embodiment, a slide groove is provided on the shell body 111, and a slider matching the slide groove is provided on the cover plate 112. By pushing and pulling the cover plate 112, the shell 110 can be opened, making it convenient for maintenance workers to repair the radar speed measurement component inside the shell 110.

[0052] In one possible implementation, referring to Figure 1 As shown, a lock buckle 115 is fixedly provided on the second end of the cover plate 112, and a lock 116 is fixedly provided on the edge of the shell body 111 near the second end of the cover plate 112. The lock 116 and the lock buckle 115 are configured to interlock or release interlocking with each other.

[0053] As an optional embodiment, the lock 116 is a side lock having a protrusion, and the lock catch 115 has a groove that matches the protrusion. Specifically, the side lock and the lock catch 115 are connected using a "concave-convex structure" to achieve higher precision and improve the tightness between the lock 116 and the lock catch 115. When the radar speed measuring device 100 is functioning normally, the lock 116 and the lock catch 115 are interlocked. When the radar speed measuring device 100 malfunctions, the lock 116 and the lock catch 115 are released from interlocking, allowing the cover 112 to rotate relative to the housing body 111.

[0054] In order to prevent the lock 116 and the lock buckle 115 from being worn during frequent opening and closing, thereby affecting the tightness of the lock 116, in this embodiment, a wear-resistant coating is provided on the contact surface of the lock 116 and the lock buckle 115 to increase the wear resistance of the lock 116.

[0055] In another embodiment that can be implemented, the lock 116 is a magnetic lock, and the lock buckle 115 is a magnetic metal material. When the cover 112 moves close to the shell body 111, the magnetic lock relies on magnetic force to attract the lock buckle 115 and the lock 116 together to achieve an interlocking effect.

[0056] In one possible implementation, referring to Figure 1 and Figure 4 As shown, there are a plurality of locks 116 , and the plurality of locks 116 are disposed on the housing body 111 at intervals along the second direction.

[0057] In this embodiment, a plurality of locks 116 are provided along the extension direction of the shell body 111. The purpose of such a setting is to provide multiple protections to improve the sealing of the shell 110 and prevent non-staff from opening the shell 110 and damaging the radar speed measurement component 120 inside the shell 110, thereby interfering with traffic management order.

[0058] In one possible implementation, referring to Figures 1 to 4 As shown, a support member 130 is further included, and the housing 110 is detachably connected to the support member 130 .

[0059] In this embodiment, the support member 130 is a pillar standing next to the road. A mounting portion is provided on the support member 130, and the shell 110 is fixedly connected to the support member 130 through the mounting portion. In this embodiment, the number of support members 130 is not limited. For example, the number of support members 130 is one, and the two ends of the shell 110 along its extension direction are respectively fixed on the support member 130, and the position of the shell 110 can be adjusted relative to the support member 130, so that the radar speed meter 121 can accurately detect the vehicle's position information.

[0060] In another feasible embodiment, the support member 130 is a support frame, and the housing 110 is fixedly disposed on the support frame.

[0061] In one possible implementation, referring to Figure 3 and Figure 4 As shown, it also includes a first connecting member 140 and a second connecting member 150. The first connecting member 140 is fixedly arranged on the outer surface of the shell body 111, and the second connecting member 150 is arranged around the peripheral side of the support member 130. The first connecting member 140 and the second connecting member 150 are both provided with mounting holes, and the mounting holes are configured for bolts to pass through to fixedly connect the first connecting member 140 and the second connecting member 150.

[0062] In this embodiment, the first connecting member 140 is a fixed slot, and the second connecting member 150 is a clamp, which is inserted into the fixed slot, wherein the clamp includes two semicircular clamps, which are arranged around the circumference of the support member 130, and the two semicircular clamps are fixedly connected by bolts.

[0063] In one possible implementation, referring to Figures 1 to 4 As shown, a solar module 160 is also included, and the solar module 160 is disposed on the top of the support member 130;

[0064] The solar assembly 160 includes a solar panel 161 and a mounting bracket 162 . The solar panel 161 is fixedly mounted on the mounting bracket 162 , and the mounting bracket 162 is fixedly connected to the support member 130 .

[0065] In this embodiment, there is an angle between the solar panel 161 and the mounting bracket 162, and the angle between the solar panel 161 and the mounting bracket 162 can be adjusted, which can ensure that the solar panel 161 can receive sunlight at the optimal angle most of the time, thereby improving energy conversion efficiency. In addition, the tilted solar panel 161 is not easy to accumulate dust, which can improve the photoelectric conversion efficiency.

[0066] In one possible implementation, referring to Figure 1 As shown, the battery assembly 170 is further included. The battery assembly 170 is disposed in the accommodating cavity 113. The battery assembly 170 and the solar assembly 160 are both electrically connected to the controller 122 so that one of the battery assembly 170 and the solar assembly 160 can selectively power the radar speed measurement assembly 120.

[0067] The battery assembly 170 includes a rechargeable battery, which is connected to the solar assembly 160 and is used to store the electricity generated by the solar assembly 160 in the battery assembly 170 .

[0068] Among them, on sunny days, the solar panel 160 generates electricity, and the controller 122 transmits the electricity to the battery panel 170 for charging, and can also directly supply power to the radar speed measurement component 120; on rainy days or at night, the solar panel 160 cannot generate enough electricity, and the controller 122 will automatically switch to using the battery panel 170 for power supply.

[0069] In this embodiment, the type of the rechargeable battery is not limited. For example, the rechargeable battery may be a lead-acid battery, a lithium-ion battery, or the like.

[0070] In this embodiment, the solar energy component 160 is used to power the radar speed measurement component 120, which has the advantages of rationally utilizing natural energy, energy saving and environmental protection.

[0071] In one possible implementation, referring to Figure 2 As shown, the radar speed meter 121 includes a radar probe 126 , which is disposed on a side of the cover plate 112 away from the accommodating cavity 113 .

[0072] Continue to refer Figure 2 As shown, radar probe 126 is positioned at the bottom of cover plate 112, and its height from the ground is between 1.5 and 3 meters. This ensures that the radar beam covers the front and rear of the target vehicle, thereby obtaining an accurate speed value. Specifically, a radar cover is provided on the outer surface of radar probe 126 to protect it from damage.

[0073] As an optional implementation, the radar probe 126 is a continuous wave radar probe. When in operation, the continuous wave radar probe emits continuous electromagnetic waves and calculates the speed of the vehicle by measuring the phase change of the reflected wave.

[0074] In a feasible embodiment, a camera (not shown in the figure) is further included. The camera is arranged above the support member 130 and is used to capture speeding vehicles.

[0075] In this embodiment, a camera is provided above the support member 130, and the camera is electrically connected to the controller 122. When the radar detector 121 detects that the real-time speed of the vehicle exceeds the maximum speed specified in the road section, the camera takes a photo of the speeding vehicle to collect evidence, and the captured photos can be uploaded to the smart traffic management system to facilitate traffic management personnel to maintain traffic order.

[0076] Therefore, embodiments of the present application provide a radar speed measuring device that utilizes a separate housing and cover plate, movably connecting the housing and cover plate so that the cover plate can rotate relative to the housing. Thus, when the radar speed measuring device is in normal operation, the cover plate covers the housing, preventing dust and rain from entering the housing and damaging components within. When the radar speed measuring device malfunctions, the cover plate moves away from the housing to expose the components within the housing, facilitating troubleshooting and repairs by maintenance personnel. By electrically connecting the radar speed meter and an electronic display to a controller, signals detected by the radar speed meter are transmitted to the controller. The controller then processes and analyzes the signals detected by the radar speed meter to obtain a vehicle speed value. The processed speed value is displayed on the electronic display, allowing passing drivers to view the real-time vehicle speed and serve as a warning. This prevents drivers from entering areas where speed reduction is required and continuing to drive at high speeds without noticing speed reduction signs, leading to traffic violations. At the same time, by arranging the controller in the accommodating cavity and arranging the radar speed meter and the electronic display on the cover plate, the problem of the wiring harness being entangled due to the lengthy wiring harness is avoided, and the system has the advantages of easy assembly.
