Description

Technical Field

[0001] The utility model relates to the technical field of door opening blind area searchlights, in particular to a radar searchlight structure for blind areas to prevent "door-opening collision". Background Art

[0002] Although cars bring us a lot of convenience, driving also has many potential safety hazards. The numerous traffic accidents that occur every day are the best proof. Due to the irregular behaviors of drivers and passengers when using vehicles, especially when getting out of the car and opening the door, it often causes collisions with surrounding motor vehicles or pedestrians, resulting in traffic accidents. The existing technology cannot well remind drivers and passengers to pay attention to the conditions of surrounding motor vehicles, posing a relatively large potential traffic safety hazard. Although there are rearview mirrors on cars to observe objects or vehicles behind the car, the rearview mirrors have blind areas and relatively low accuracy, and they can no longer meet people's needs when opening the door. With the rapid development of automotive safety and intelligence, the door opening warning function is a basic safety function of intelligent driving.

[0003] During the existing process of opening the door, the driver or passenger can often only observe whether there are moving vehicles or passing pedestrians behind through the rearview mirror. However, due to the limitation of the searchlight of the rearview mirror, it can often only search the rear space between the opened door and the vehicle body, and cannot search the outer space of the opened door. That is to say, the outer space of the opened door belongs to the searchlight blind area of the rearview mirror, and moving vehicles or passing pedestrians in this space are likely to cause "door-opening collision".

[0004] Therefore, it is very necessary to invent a radar searchlight structure for blind areas to prevent "door-opening collision" to solve the above problems. Content of the Utility Model

[0005] To solve the deficiencies of the existing technology, the purpose of the utility model is to provide a radar searchlight structure for blind areas to prevent "door-opening collision", which solves the problem in the existing technology that due to the limitation of the searchlight of the rearview mirror, it can often only search the rear space between the opened door and the vehicle body, and cannot search the outer space of the opened door. That is to say, the outer space of the opened door belongs to the searchlight blind area of the rearview mirror, and moving vehicles or passing pedestrians in this space are likely to cause "door-opening collision".

[0006] To achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A radar search structure for blind spots to prevent "door-opening kill", comprising a car door panel and a mounting block detachably installed inside the car door panel. An installation groove with an open end facing outside the car is provided in the mounting block. A U-shaped fixing frame is arranged in the installation groove. A rotating assembly is rotatably arranged in the U-shaped fixing frame.

A rack plate is installed at the end of the pushing assembly. The rack plate is meshed and connected with the rotating assembly. The rotating assembly is installed with a detection assembly for detecting the blind spot outside the car door panel. A plastic guide plate through which the detection assembly can penetrate is installed at the open end of the installation groove;

[0008] When the car door panel is opened, the pushing assembly actively extends and retracts, and forces the rotating assembly to rotate to drive the detection assembly to point to the blind spot angle outside the car door.

[0009] As a preferred solution of the present utility model, clamping grooves are provided on both side parts of the U-shaped fixing frame. The rotating assembly includes a rotating cylinder and rotating rods arranged in the middle of both ends of the rotating cylinder. The two rotating rods are respectively rotatably clamped in the corresponding clamping grooves.

[0010] As a preferred solution of the present utility model, a gear disc is detachably sleeved in the middle of the rotating cylinder. The rack plate is meshed and connected with the gear disc.

[0011] As a preferred solution of the present utility model, insertion holes are symmetrically arranged on the circumferential side wall of the rotating cylinder. The detection assembly includes two insertion posts detachably inserted into the insertion holes, a connecting plate detachably installed between the two insertion posts, and a millimeter-wave radar assembly installed in the middle of one side wall of the connecting plate.

[0012] As a preferred solution of the present utility model, a positioning stud is provided at one end of each insertion post outside the insertion hole. The connecting plate is detachably clamped between the two positioning studs, and a nut for locking the position of the connecting plate is threadedly sleeved on the positioning stud.

[0013] As a preferred solution of the present utility model, the pushing assembly includes a mounting seat installed in the installation groove and a push rod member arranged on one side wall of the mounting seat. The other end of the push rod member is detachably connected to one end face of the rack plate.

[0014] As a preferred solution of the present utility model, a guiding column is connected to one end of the U-shaped fixing frame close to the mounting seat. A sliding seat that can slide along the guiding column is installed at the bottom end of the rack plate.

[0015] In the above technical solution, the technical effects and advantages provided by the present utility model:

[0016] In the present utility model, in the initial state, the detection component points to the rear of the vehicle, which is convenient for fixing in the installation groove. After the driver or passenger opens the door, during the process of the door panel gradually opening outwards, the pushing component receives the signal of the door panel opening in real time and actively expands and contracts, thereby promoting the transverse sliding of the rack plate, and then driving the rotating component to rotate within the U-shaped fixing frame, and then gradually switching the searchlight component from pointing to the rear of the vehicle to pointing to the outside of the door panel, and then passing through the plastic guide plate through the searchlight component and pointing to the outside space of the door panel, so as to conduct anti-collision detection on the driving vehicle and passing pedestrians in the blind area space outside the door panel, avoid the "door-opening kill" in this blind area space, and finally through the cooperation of the searchlight component and the rearview mirror for searchlighting, conduct simultaneous anti-collision detection on the space between the door panel and the vehicle body and the space outside the door panel, avoid the "door-opening kill" in different spaces, and finally improve the safety of opening the door panel and the effect of preventing the "door-opening kill".

[0024] The present utility model will be further described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0025] The present utility model provides as Figures 1-5A radar search structure for blind spots to prevent "door-opening kill" as shown, includes a car door panel 1 and a mounting block 2 detachably installed inside the car door panel 1. An installation groove 3 with an open end facing outside the vehicle is provided inside the mounting block 2. A U-shaped fixing frame 4 is arranged inside the installation groove 3. A rotating assembly is rotatably arranged inside the U-shaped fixing frame 4. And a pushing assembly that can receive the signal of the car door panel 1 being opened and actively extend and retract is installed inside the installation groove 3. A rack plate 18 is installed at the end of the pushing assembly. The rack plate 18 is meshed and connected with the rotating assembly. The rotating assembly is installed with a detection assembly for detecting the blind spot outside the car door panel 1. A plastic guide plate 15 through which the detection assembly can penetrate is installed at the open end of the installation groove 3. In order to avoid the influence of the millimeter-wave radar assembly 14 on the driver or passengers of the car door, its effective search distance is set to about 4 meters;

[0026] When the car door panel 1 is opened, the pushing assembly actively extends and retracts, and forces the rotating assembly to rotate to drive the detection assembly to point to the blind spot angle outside the car door.

[0027] Card slots 7 are provided on both side parts of the U-shaped fixing frame 4. The rotating assembly includes a rotating cylinder 9 and rotating rods 8 provided in the middle of both ends of the rotating cylinder 9. The two rotating rods 8 are respectively rotatably clamped in the corresponding card slots 7. During the process of the rack plate 18 driving the rotating cylinder 9 to rotate, the rotating rods 8 rotate synchronously in the corresponding card slots 7. At the same time, just take out the rotating rods 8 from the clamped positions in the card slots 7 and the disassembly of the detection assembly can be completed.

[0028] A gear disk 19 is detachably sleeved in the middle of the rotating cylinder 9. The rack plate 18 is meshed and connected with the gear disk 19. When the rack plate 18 moves, it drives the meshed gear disk 19 to rotate, and then drives the rotating cylinder 9 to rotate, that is, drives the detection assembly to rotate.

[0029] Insertion holes 10 are symmetrically arranged on the circumferential side wall of the rotating cylinder 9. The detection assembly includes two plug posts 11 detachably inserted into the insertion holes 10, a connecting plate 13 detachably installed between the two plug posts 11, and a millimeter-wave radar assembly 14 installed in the middle of one side wall of the connecting plate 13. By taking out the plug posts 11 from the insertion holes 10, the separation and disassembly between the detection assembly and the rotating assembly can be completed.

[0030] A positioning stud 12 is provided at one end of each plug post 11 outside the insertion hole 10. The connecting plate 13 is detachably clamped between the two positioning studs 12. And a nut 20 for locking the position of the connecting plate 13 is threadedly sleeved on the positioning stud 12. By loosening the nut 20, the fixation of the connecting plate 13 can be released, and then it is convenient to take out the millimeter-wave radar assembly 14 from the detection assembly.

[0031] The pushing component includes a mounting seat 5 installed in the mounting groove 3 and a push rod member 6 provided on one side wall of the mounting seat 5. The other end of the push rod member 6 is detachably connected to one end face of the rack plate 18. A guide post 16 is connected to one end of the U-shaped fixing bracket 4 close to the mounting seat 5. A sliding seat 17 that can slide along the guide post 16 is installed at the bottom end of the rack plate 18. The push rod member 6 is an electric push rod. When the car door panel 1 is opened, the push rod member 6 receives the car door opening signal and actively expands and contracts, thereby causing the rack plate 18 to slide horizontally. During this process, the sliding seat 17 slides synchronously along the guide post 16 to limit the sliding of the rack plate 18, and then drives the rotating component to rotate within the U-shaped fixing bracket 4, and then gradually switches the searchlight component from pointing to the rear of the vehicle to pointing to the outside of the car door panel 1.

[0032] In the present utility model, in the initial state, the detection component points to the rear of the vehicle, which is convenient for fixing in the mounting groove 3. After the driver or passenger opens the car door, during the process of the car door panel 1 gradually opening outwards, the pushing component receives the car door opening signal in real time and actively expands and contracts, thereby causing the rack plate 18 to slide horizontally, and then drives the rotating component to rotate within the U-shaped fixing bracket 4, and then gradually switches the searchlight component from pointing to the rear of the vehicle to pointing to the outside of the car door panel 1, and then through the searchlight component passing through the plastic guide plate 15 and pointing to the outside space of the car door panel 1, anti-collision detection of oncoming vehicles and passing pedestrians in the blind area space outside the car door panel 1 is carried out to avoid the "door-opening kill" in this blind area space. Finally, through the cooperation of the searchlight component and the rearview mirror for searchlighting, anti-collision detection of the space between the car door panel 1 and the vehicle body and the outside space of the car door panel 1 is carried out simultaneously to avoid the "door-opening kill" in different spaces, and finally the safety of opening the car door panel 1 and the effect of preventing the "door-opening kill" are improved.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the technical principle of the present utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
