Description

Technical Field

[0001] The utility model relates to the technical field of geomagnetic vehicle detectors, in particular to a protective cover for a geomagnetic vehicle detector. Background Technique

[0002] For a geomagnetic vehicle detector, ferromagnetic substances contained in the vehicle itself will affect the geomagnetic signal in the area where the vehicle is located, causing the earth's magnetic field lines in the area where the vehicle is located to bend. When a vehicle passes near the sensor, the sensor can sensitively detect the change of the signal, and relevant information of the detection target can be obtained through signal analysis. In order to protect the geomagnetic vehicle detector, a protective cover is usually installed to reduce the risk of the geomagnetic vehicle detector being crushed.

[0003] At present, the protective cover is usually fixedly connected to the geomagnetic vehicle detector by connecting bolts. In order to make the connection between the protective cover and the geomagnetic vehicle detector firm, usually two or more connecting bolts are used to fixedly connect the protective cover and the geomagnetic vehicle detector. The use of two or more connecting bolts makes the tightening of the connecting bolts need to be repeated two or more times, which will result in a lower disassembly and installation efficiency between the protective cover and the geomagnetic vehicle detector. In addition, the connecting bolts may be broken off in the connecting holes on the geomagnetic vehicle detector during the tightening process, which will cause inconvenience to the disassembly and installation between the protective cover and the geomagnetic vehicle detector.

Detailed Description of the Preferred Embodiment

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Please refer to Figures 1 to 7, as an embodiment of the present utility model, the protective cover of the geomagnetic vehicle detector includes a protective cover body 3 and a shell cover 2 provided on the protective cover body 3. A geomagnetic vehicle detector body 1 is provided on the shell cover 2, and a connecting component is provided between the protective cover body 3 and the geomagnetic vehicle detector body 1;

[0026] The geomagnetic vehicle detector body 1 is used to detect information of nearby moving vehicles. The protective cover body 3 is used to protect the geomagnetic vehicle detector body 1 buried in the ground. The connecting component is used to connect the protective cover body 3 to the geomagnetic vehicle detector body 1.

[0027] In this embodiment, first place the protective cover body 3 on the shell cover 2. After adjusting the protective cover body 3 to a suitable position, rotate the connecting component. During the rotation of the connecting component, it will be inserted into the shell cover 2 through multiple orientations, thereby connecting the connecting component to the shell cover 2, so that the protective cover body 3 and the geomagnetic vehicle detector body 1 are connected. By rotating the connecting component, the protective cover body 3 can be inserted and connected through multiple orientations, thereby completing the connection between the protective cover body 3 and the geomagnetic vehicle detector body 1. This can not only save the use of connecting bolts, but also improve the disassembly and installation efficiency between the protective cover body 3 and the geomagnetic vehicle detector body 1, and can also avoid the problem that the connecting bolt breaks in the connection hole of the geomagnetic vehicle detector body 1 and cannot be taken out during the tightening process.

[0028] As a further solution of the present utility model, the connecting component includes a groove 4 opened on the shell cover 2 and a turntable 5 rotatably connected to the protective cover body 3. The turntable 5 is clamped in the groove 4. A locking groove 6 is opened in the groove 4. A first sliding groove 7 is opened on the turntable 5. A first slider 8 is slidably connected in the first sliding groove 7. A locking plate 9 is rotatably connected to the first slider 8. The locking plate 9 corresponds to the locking groove 6 in the groove 4 in position. A rotating shaft 10 is fixedly provided on the turntable 5. The rotating shaft 10 passes through the protective cover body 3. A limiting and guiding component is provided between the locking plate 9 and the groove 4.

[0029] Among them, two or more locking plates 9 are provided. In this case, four are provided. The size of the locking plate 9 is smaller than the notch size of the locking groove 6. There is a gap between the starting point of the stroke of the locking plate 9 and the inner wall surface of the groove 4. This can prevent external water stains from immersing dust particles into the groove 4 and the dust particles in the groove 4 from mixing into the locking groove 6, resulting in the notch of the locking groove 6 becoming smaller, and then the locking plate 9 cannot be inserted into the locking groove 6, and the locking plate 9 cannot be completely moved to the starting point of the stroke, resulting in the locking plate 9 being completely pulled out of the locking groove 6, and further resulting in the turntable 5 not being able to be taken out of the groove 4, and further making the protective cover body 3 unable to be separated from the shell cover 2.

[0030] As a further solution of the present utility model, the limit guiding assembly includes a limit groove 19 opened in the groove 4 and a limit block 20 fixedly arranged on the lock plate 9. The limit groove 19 in the groove 4 corresponds to the limit block 20 on the lock plate 9 in position, and the limit block 20 on the lock plate 9 is slidably connected in the limit groove 19 in the groove 4. One end of the rotating shaft 10 passing through the protective cover body 3 is fixedly provided with a rotating block 22, and a hand-holding notch is opened on the outer wall surface of the rotating block 22. A plurality of hand-holding notches are arranged in sequence, and the cross section of the hand-holding notch is arc-shaped.

[0031] In this embodiment, when it is necessary to connect the protective cover body 3 with the shell cover 2 on the geomagnetic vehicle detector body 1, first insert the turntable 5 into the groove 4, and make the lock plate 9 on the turntable 5 correspond to the lock groove 6 in the groove 4 in position, and the limit block 20 on the lock plate 9 is inserted into the limit groove 19 in the groove 4. Then rotate the rotating block 22. During the rotation of the rotating block 22, the lock plate 9 moves along the limit groove 19 towards the lock groove 6 through the first slider 8 until the lock plate 9 is completely inserted into the lock groove 6 in the groove 4. At this time, the connection between the protective cover body 3 and the geomagnetic vehicle detector body 1 can be completed. If it is necessary to disassemble the protective cover body 3 from the geomagnetic vehicle detector body 1, rotate the rotating block 22 in the reverse direction, so that the lock plate 9 is completely removed from the lock groove 6, and finally the protective cover body 3 can be taken off from the geomagnetic vehicle detector body 1. Through the setting of the connection assembly, not only can the disassembly and installation efficiency between the protective cover body 3 and the geomagnetic vehicle detector body 1 be improved, but also the problem that the connection bolt breaks in the connection hole on the geomagnetic vehicle detector body 1 and cannot be taken out during the tightening process can be avoided. In addition, the mutual cooperation between the limit groove 19 and the limit block 20 plays a role in limiting the lock plate 9, avoiding the lock plate 9 from rotating in the groove 4 as the turntable 5 rotates.

[0032] As a further solution of the present utility model, a limit port is opened in the groove 4, a fixed block 21 is fixedly arranged on the turntable 5, the fixed block 21 corresponds to the limit port in position, and the fixed block 21 is inserted into the limit port.

[0033] Among them, the setting of the fixed block 21 not only plays a role in supporting the turntable 5, but also can reduce the contact area between the turntable 5 and the groove 4, thereby reducing the friction force between the turntable 5 and the groove 4. The caliber size of the limit port is adapted to the diameter size of the fixed block 21, so that the outer wall surface inserted into the limit port can be fitted with the inner wall surface of the limit port.

[0034] As a further solution of the present utility model, a parking space ground lock assembly is provided on the protective cover body 3. The parking space ground lock assembly includes a baffle 11 rotatably connected to the protective cover body 3 and a placement groove 12 opened on the protective cover body 3. A support plate 13 is arranged in the placement groove 12. One end of the support plate 13 is rotatably connected to the baffle 11. A second sliding groove 14 is opened in the placement groove 12. A second sliding block 15 is slidably connected in the second sliding groove 14. The other end of the support plate 13 is rotatably connected to the second sliding block 15. A lead screw 16 is rotatably connected in the second sliding groove 14. The second sliding block 15 in the second sliding groove 14 is sleeved on the lead screw 16. A driving assembly is arranged in the protective cover body 3. The lead screw 16 is docked with the driving assembly. The driving assembly includes a transmission member 17 rotatably connected in the protective cover body 3 and a servo motor 18 fixedly arranged in the protective cover body 3. One end of the lead screw 16 is docked with the transmission member 17. The output end of the servo motor 18 is docked with the transmission member 17. Among them, the servo motor 18 and the geomagnetic vehicle detector body 1 are electrically connected.

[0035] In this embodiment, when the vehicle in the parking space drives away from the parking space, the geomagnetic vehicle detector body 1 will transmit an electrical signal to the servo motor 18. The servo motor 18 starts. The servo motor 18 drives the transmission member 17 to rotate. The rotation of the transmission member 17 drives the lead screw 16 to rotate. The rotation of the lead screw 16 drives the second sliding block 15 to slide in the second sliding groove 14. The sliding of the second sliding block 15 pushes the support plate 13 to flip. During the flipping process of the support plate 13, it will push the baffle 11 to flip. When the baffle 11 flips to an appropriate angle, the servo motor 18 automatically shuts down, thus forming a parking space ground lock. When the vehicle drives near the geomagnetic vehicle detector body 1, the geomagnetic vehicle detector body 1 will detect and analyze whether it is the vehicle information of this parking space. If it is the vehicle of this parking space, the geomagnetic vehicle detector body 1 will start the servo motor 18 through an electrical signal. The servo motor 18 will retract the raised baffle 11 into the protective cover body 3 so that the car owner can park the car in the parking space.

[0036] Through the setting of the parking space ground lock assembly, it can be avoided that when the car owner drives away from the parking space, other car owners will occupy the parking space, so that the car owner cannot park the car when he comes back, thus causing certain trouble to the car owner. In addition, through the electrical cooperation between the geomagnetic vehicle detector body 1 and the parking space ground lock assembly, the parking space ground lock assembly has an automatic lifting function, making the use of the parking space ground lock assembly more intelligent and convenient.

[0037] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of the present utility model, all technical solutions that can implement the present utility model in other specific forms are included in the present utility model.
