Description

Technical Field

[0001] The utility model relates to the technical field of RFID reader installation, in particular to an installation structure of a vehicle RFID reader. Background Technique

[0002] In recent years, the application of RFID technology in tunnel traffic event management has gradually increased, mainly for the real-time positioning and information tracking of rescue vehicles. Currently, generally, one group of RFID electronic tags is respectively pasted on both sides of the tunnel inner wall every 10 meters, at 1.7 meters and 2.2 meters respectively (for positioning vehicles at different heights). These tags contain unique identification codes for identifying vehicles related to operation management such as patrol and breakdown clearance. The tags are internally provided with antennas and chips, capable of receiving and sending radio frequency signals. It is necessary to install RFID readers on vehicles related to operation management such as patrol and breakdown clearance. The reader communicates with the RFID tags pasted in the tunnel by transmitting radio frequency signals to read the information in the tags. Each RFID reader is equipped with an antenna array for expanding the signal coverage range and improving the positioning accuracy. The antenna array can precisely control the transmitting and receiving directions of the signal to achieve coverage of different areas in the tunnel. The reader sends the received data to the operation command and dispatch system of the river-crossing tunnel. The system calculates the precise position of the rescue vehicle in the tunnel based on the received data. Currently, general RFID readers are directly fixed on vehicles related to operation management such as patrol and breakdown clearance by screws. When the RFID reader is damaged, it is not convenient to replace it. Therefore, we propose an installation structure of a vehicle RFID reader to solve the above problems.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] Such as Figures 1-5As shown in the figure, an installation structure of a vehicle RFID reader / writer proposed by an embodiment of the present utility model includes an installation box body 1. On the front surface of the installation box body 1, there is an RFID reader / writer main body 2. Four insertion blocks 3 are symmetrically fixed on the back surface of the RFID reader / writer main body 2. Card holes 4 are formed on the surfaces of the insertion blocks 3. Four insertion ports 5 adapted to the insertion blocks 3 are symmetrically formed on the front surface of the installation box body 1. A screw rod 6 is threadedly connected to the top of the installation box body 1. A threaded hole 16 adapted to the screw rod 6 is formed in the top of the installation box body 1. A knob 7 is fixed to the top end of the screw rod 6. The bottom end of the screw rod 6 is rotationally connected to an installation block 8 through a bearing. Both side walls of the installation block 8 are rotationally connected to a connecting rod 9 through a pin shaft. The bottom ends of the connecting rods 9 are rotationally connected to a vertical plate 10 through a pin shaft. The vertical plates 10 are all slidably connected inside the installation box body 1. Two card blocks 11 adapted to the card holes 4 are symmetrically fixed on one side wall of each vertical plate 10. Two connecting pieces 12 are symmetrically fixed on both side walls of the installation box body 1. Installation holes 13 are formed on the surfaces of the connecting pieces 12. During use, the four connecting pieces 12 are fixed on vehicles related to operation management such as patrol and obstacle removal with screws, so that the installation box body 1 can be fixed on the vehicle. Then, the RFID reader / writer main body 2 is installed on the installation box body 1. When the RFID reader / writer main body 2 is damaged and needs to be replaced, the disassembly process is as follows: Rotate the knob 7. The knob 7 will drive the screw rod 6 to rotate upward. The screw rod 6 will drive the installation block 8 to move upward. The installation block 8 will drive the two connecting rods 9 to move. The connecting rods 9 will drive the corresponding vertical plates 10 to move toward the middle. The vertical plates 10 will drive the corresponding card blocks 11 to move toward the middle, so that the card blocks 11 can be disengaged from the card holes 4 on the corresponding insertion blocks 3. In this way, the insertion blocks 3 can be pulled out of the installation box body 1, and thus the RFID reader / writer main body 2 can be disassembled from the installation box body 1. The process of installing the RFID reader / writer main body 2 on the installation box body 1 will not be elaborated here.

[0025] As Figure 3 shown, in some embodiments, a first telescopic sleeve 14 is fixed to the bottom of the installation block 8. The bottom end of the first telescopic sleeve 14 is fixedly connected to the bottom inner wall of the installation box body 1, so as to make the installation block 8 move more stably in the vertical direction. A second telescopic sleeve 15 is fixed to one side wall of each vertical plate 10. One end of the second telescopic sleeve 15 is fixedly connected to the adjacent side inner wall of the installation box body 1, so as to make the vertical plates 10 move more stably inside the installation box body 1.

[0026] As Figure 1 and Figure 4 shown, in some embodiments, anti-slip patterns are formed on the surface of the knob 7, which can play a good anti-slip role, thus facilitating the user to rotate the knob 7.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
