Description

Technical Field

[0001] This utility model relates to the field of highway inspection vehicles, and more specifically, to a highway inspection LED screen warning vehicle. Background Technology

[0002] Highway inspection vehicles are important tools for road inspectors. They are generally used as transportation vehicles to move inspection instruments, or they can be equipped with corresponding inspection equipment and processing software to enable them to perform certain inspections.

[0003] Chinese utility model patent application CN206859020U discloses "A Highway Inspection LED Screen Warning Vehicle", which includes a vehicle body, a telescopic detector, an LED screen lifting bracket, and an LED screen. The vehicle body is equipped with an LED screen lifting bracket, and the LED screen is mounted on the LED screen lifting bracket. A signal comparison device is installed inside the vehicle body and connected to the LED screen. The LED screen plays back the signal, reducing detection time and increasing detection efficiency. It is suitable for widespread use, and the direct comparison of information on the LED screen is convenient.

[0004] In the above solution, the LED screen is set up in an open-air environment. However, since road inspections are carried out outdoors, the road inspection vehicle may encounter extreme weather such as rain, snow, hail, and thunderstorms during the inspection process. The LED screen set up outdoors is easily affected by the external weather and is prone to damage, which will affect the normal operation of the road inspection vehicle. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a highway inspection LED screen warning vehicle, which can enable the LED screen mounted on the highway inspection vehicle to work in various weather conditions, is not easily damaged by the LED screen, and does not easily affect the normal operation of the highway inspection vehicle.

[0006] To solve the above problems, this utility model adopts the following technical solution: a highway inspection LED screen warning vehicle, including a vehicle body, a cavity is opened in the vehicle body, a movable groove is opened on the top plate of the cavity, a crossbar is fixedly connected between the side walls of the movable groove, a hook is sleeved on the crossbar, a compression spring is fixedly connected between the hook and the two side walls of the movable groove, and both compression springs are sleeved on the crossbar, the lower end of the hook is fixedly connected to the LED screen body, a transparent acrylic plate is hinged to the opening of the cavity, a limiting plate matching the transparent acrylic plate is fixedly connected to the bottom plate of the cavity, a magnet is fixedly connected to the end of the limiting plate near the transparent acrylic plate, and an iron block matching the magnet is embedded in the transparent acrylic plate. This allows the LED screen mounted on the highway inspection vehicle to work in various weather conditions, is not easily damaged, and does not easily affect the normal operation of the highway inspection vehicle.

[0007] Furthermore, multiple heat dissipation holes are distributed on the transparent acrylic plate. The channels of the heat dissipation holes are vertically shaped like a "Z". These heat dissipation holes allow the heat generated by the LED screen to be discharged from the cavity. The high inner and low outer shape of the heat dissipation holes prevents water droplets from entering the cavity through the holes during rain, thus minimizing their impact on the LED screen. Dustproof mesh is fixedly connected inside the heat dissipation holes, preventing dust and other debris from entering the cavity through the holes and minimizing their impact on the LED screen.

[0008] Furthermore, a wear-resistant layer is fixedly connected to the inner wall of the heat dissipation hole, and anti-slip texture is engraved on the wear-resistant layer. The heat dissipation hole can be used as a hidden handle, while the anti-slip texture can prevent workers from slipping when using the heat dissipation hole to open the transparent acrylic sheet.

[0009] Furthermore, a rubber sleeve is connected between the crossbar and the hook, and the rubber sleeve is fixedly connected to the hook. The rubber sleeve can reduce the impact of vibration generated by the vehicle body and crossbar during driving on the hook and the main body of the LED screen, so that the main body of the LED screen can work more stably.

[0010] Furthermore, a sealing rubber gasket is fixedly connected between the vehicle body and the transparent acrylic panel, and the sealing rubber gasket is fixedly connected to the vehicle body. The sealing rubber gasket can increase the sealing between the vehicle body and the transparent acrylic panel, making it difficult for external liquid water to enter the cavity through the gap between the vehicle body and the transparent acrylic panel, and thus less likely to cause adverse effects on the LED screen body.

[0011] Furthermore, a shock-absorbing rubber ring is fixedly connected to one end of the limiting plate near the transparent acrylic plate, and the shock-absorbing rubber ring is sleeved on the outside of the magnet block. The shock-absorbing rubber ring has a buffering effect, so that the magnet block and the iron block are not easily subjected to direct and violent impact during the closing process of the transparent acrylic plate, and the magnet block and the iron block are not easily damaged.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) This solution enables the LED screen mounted on the highway inspection vehicle to work in all kinds of weather conditions, and it is not easy to damage the LED screen or affect the normal operation of the highway inspection vehicle.

[0014] (2) Multiple heat dissipation holes are drilled in the transparent acrylic plate. The heat dissipation holes are vertical "Z" shaped. The heat dissipation holes are heat dissipation holes, which allow the heat generated by the LED screen body to be discharged from the cavity. The high inner and low outer shape of the heat dissipation holes can prevent water droplets from entering the cavity through the heat dissipation holes when it rains, so as not to have an adverse effect on the LED screen body. A dustproof net is fixedly connected inside the heat dissipation holes. The dustproof net can prevent dust and other debris from entering the cavity through the heat dissipation holes, so as not to have an adverse effect on the LED screen body.

[0015] (3) A wear-resistant layer is fixedly connected to the inner wall of the heat dissipation hole. The wear-resistant layer is engraved with anti-slip texture. The heat dissipation hole can be used as a hidden handle, while the anti-slip texture can prevent the staff from slipping when using the heat dissipation hole to open the transparent acrylic sheet.

[0016] (4) A rubber sleeve is connected between the crossbar and the hook, and the rubber sleeve is fixedly connected to the hook. The rubber sleeve can reduce the impact of the vibration generated by the vehicle body and crossbar during driving on the hook and the main body of the LED screen, so that the main body of the LED screen can work more stably.

[0017] (5) A sealing rubber gasket is fixedly connected between the vehicle body and the transparent acrylic sheet, and the sealing rubber gasket is fixedly connected to the vehicle body. The sealing rubber gasket can increase the sealing between the vehicle body and the transparent acrylic sheet, so that external liquid water is not easy to enter the cavity through the gap between the vehicle body and the transparent acrylic sheet, and is not easy to cause adverse effects on the LED screen body.

[0018] (6) A shock-absorbing rubber ring is fixedly connected to one end of the limiting plate near the transparent acrylic plate, and the shock-absorbing rubber ring is sleeved on the outside of the magnet block. The shock-absorbing rubber ring has a buffering effect, so that the magnet block and the iron block are not easily violently impacted during the closing process of the transparent acrylic plate, and the magnet block and the iron block are not easily damaged.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example 1:

[0029] Please see Figure 1-2A highway inspection LED screen warning vehicle includes a vehicle-mounted body 1 with a cavity 2 inside. A movable groove 4 is formed on the top plate of the cavity 2. A crossbar 5 is fixedly connected between the side walls of the movable groove 4. A hook 6 is sleeved on the crossbar 5. Compression springs 7 are fixedly connected between the hook 6 and both side walls of the movable groove 4, and both compression springs 7 are sleeved on the crossbar 5. An LED screen body 9 is fixedly connected to the lower end of the hook 6. A transparent acrylic plate 3 is hinged to the opening of the cavity 2. When the vehicle-mounted body 1 encounters bumps and vibrations, the compression and recovery of the pair of compression springs 7 can significantly reduce the vibration and bumps of the hook 6 and the LED screen body 9, making the LED screen body 9 work more smoothly. The LED screen body 9 is electrically connected to the control panel of the highway inspection vehicle and is powered by the highway inspection vehicle. Operators can input corresponding commands to the LED screen body 9 through the control panel of the highway inspection vehicle to display corresponding text and image information, serving as a warning and notification function.

[0030] Please see Figure 4 A limiting plate 13 matching the transparent acrylic sheet 3 is fixedly connected to the bottom plate of the cavity 2. A magnet 14 is fixedly connected to one end of the limiting plate 13 near the transparent acrylic sheet 3. An iron block 15 matching the magnet 14 is embedded on the transparent acrylic sheet 3. Through the adsorption of the magnet 14 and the iron block 15, the transparent acrylic sheet 3 can be fixed more stably at the opening of the cavity 2, making it less likely for the transparent acrylic sheet 3 to open during driving on bumpy roads, and thus less likely to weaken the protective ability of the transparent acrylic sheet 3.

[0031] Please see Figure 3 Multiple heat dissipation holes 10 are distributed on the transparent acrylic sheet 3. The channels of the heat dissipation holes 10 are vertically shaped like a "Z", which allows the heat generated by the LED screen body 9 to be discharged from the cavity 2. The shape of the heat dissipation holes 10, which is higher inside and lower outside, prevents water droplets from entering the cavity 2 through the heat dissipation holes 10 during rain, thus preventing adverse effects on the LED screen body 9. A dustproof mesh 11 is fixedly connected inside the heat dissipation holes 10. The dustproof mesh 11 prevents dust and other debris from entering the cavity 2 through the heat dissipation holes 10, thus preventing adverse effects on the LED screen body 9. A wear-resistant layer is fixedly connected to the inner wall of the heat dissipation holes 10. The wear-resistant layer is engraved with anti-slip texture. The heat dissipation holes 10 can be used as a hidden handle, and the anti-slip texture prevents the operator from slipping when using the heat dissipation holes 10 to open the transparent acrylic sheet 3.

[0032] Please see Figure 1-2 and Figure 4A rubber sleeve 8 connects the crossbar 5 and the hook 6, and the rubber sleeve 8 is fixedly connected to the hook 6. The rubber sleeve 8 can reduce the impact of vibrations generated by the vehicle body 1 and the crossbar 5 during driving on the hook 6 and the LED screen body 9, so that the LED screen body 9 can work more stably. A sealing rubber gasket 12 is fixedly connected between the vehicle body 1 and the transparent acrylic plate 3, and the sealing rubber gasket 12 is fixedly connected to the vehicle body 1. The sealing rubber gasket 12 can increase the gap between the vehicle body 1 and the transparent acrylic plate 3. The airtight seal prevents external liquid water from easily entering the cavity 2 through the gap between the vehicle body 1 and the transparent acrylic plate 3, thus minimizing its adverse effects on the LED screen body 9. A shock-absorbing rubber ring is fixedly connected to one end of the limiting plate 13 near the transparent acrylic plate 3, and the shock-absorbing rubber ring is sleeved on the outside of the magnet block 14. The shock-absorbing rubber ring has a buffering effect, preventing the magnet block 14 and the iron block 15 from directly and violently impacting each other during the closing process of the transparent acrylic plate 3, thus preventing damage to the magnet block 14 and the iron block 15.

[0033] During the normal operation of the highway inspection vehicle, please refer to Figure 1 The transparent acrylic sheet 3 is firmly fixed to the opening of the cavity 2 by the adsorption between the magnet 14 and the iron block 15. The transparent acrylic sheet 3 is not easy to open due to bumps, and its protective effect is not easily affected. The LED screen body 9, due to the presence of a pair of compression springs 7 and rubber sleeves 8, will greatly reduce the impact of vibration caused by bumps in the vehicle body 1 on the LED screen body 9, so that the LED screen body 9 can work relatively stably. During normal heat dissipation, liquid water, dust and other debris from the outside are not easy to enter the cavity 2 through the heat dissipation holes 10, and will not easily affect the normal operation of the LED screen body 9. This allows the LED screen mounted on the highway inspection vehicle to work in various weather conditions without easily causing damage to the LED screen or affecting the normal operation of the highway inspection vehicle.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
