Description

Technical Field

[0001] This utility model relates to the field of electronic tag OBU, and in particular to an electronic tag OBU. Background Technology

[0002] An electronic tag OBU (On-Board Unit) typically refers to an in-vehicle device that is widely used in intelligent transportation systems. The main function of an OBU is to communicate with roadside equipment, traffic management systems, or other vehicles to achieve functions such as automatic toll collection, vehicle positioning, and data collection.

[0003] In the prior art, when installing an OBU device, adhesive backing is typically used to attach the OBU to the windshield of the vehicle.

[0004] Electronic tag OBUs typically have a tamper switch on the back. This tamper switch needs to be firmly pressed against the windshield during installation. However, with adhesive backing, the tamper switch will no longer be pressed against the windshield when the adhesive loses its effectiveness and the adhesion decreases. This can easily trigger the OBU removal command, causing the OBU to stop working properly. To address this, we propose an electronic tag OBU. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an electronic tag OBU. By setting up an installation component, the installation block is first inserted into the installation slot, and the trigger switch is pushed inward to press against it, so that the trigger switch and the micro switch installed on the built-in main board are connected. The micro switch detects whether the electronic tag OBU has been disassembled. When the trigger switch presses against the micro switch, it has not been disassembled. When the trigger switch does not press against the micro switch, the electronic tag OBU detects that it has been disassembled. Then, the mechanical self-locking knob is turned, which finally drives the insertion block to insert into the slot, thereby completing the installation of the electronic tag OBU and the installation block. With this connection method, even if the adhesive backing of the installation block becomes loose from the windshield, it will not affect the tightness between the installation block and the electronic tag OBU, so that the trigger switch will not loosen and the disassembly command will not be triggered. Therefore, the electronic tag OBU can still work normally even if the adhesive backing loses some of its stickiness.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An electronic tag OBU includes an electronic tag OBU body, an installation component connected to the lower end of the electronic tag OBU body, and an adhesive component connected to the lower end of the installation component.

[0008] The mounting assembly includes a mounting slot located at the lower end of the electronic tag OBU body. Slots are provided on the left and right sides of the inner wall of the mounting slot. A trigger switch is movably connected to the bottom of the mounting slot. A mounting block is movably connected inside the mounting slot. A pair of inserts are slidably connected inside the mounting block. The pair of inserts are symmetrically distributed on the left and right sides. The inserts extend to the outside of the mounting block and are movably inserted into the inside of the slots. The inserts are adapted to the slots.

[0009] By setting up the installation components, the installation block is first inserted into the installation slot, and the trigger switch is pushed inward to press against it, so that the trigger switch and the micro switch installed on the built-in mainboard are engaged. The micro switch detects whether the electronic tag OBU has been disassembled. When the trigger switch is pressed against the micro switch, it has not been disassembled. When the trigger switch is not pressed against the micro switch, the electronic tag OBU detects that it has been disassembled. Then, the mechanical self-locking knob is turned, which finally drives the insertion block into the slot, thus completing the installation of the electronic tag OBU and the installation block. With this connection method, even if the adhesive backing of the installation block becomes loose from the windshield, it will not affect the tightness between the installation block and the electronic tag OBU, so that the trigger switch will not become loose and the disassembly command will not be triggered. Therefore, the electronic tag OBU can still work normally even if the adhesive backing loses some of its stickiness.

[0010] Furthermore, a mechanical self-locking knob is rotatably connected to the front end of the mounting block, and a lead screw is connected to the rear end of the mechanical self-locking knob. The lead screw is rotatably connected to the mounting block, and a slider is movably connected to the outside of the lead screw, and the slider is adapted to the lead screw.

[0011] Furthermore, mounting plates are fixedly connected to both ends of the slider, and connecting rods are rotatably connected to the outside of the mounting plates. The connecting rods are symmetrically distributed on the left and right sides. A rotating shaft is rotatably connected to the end of the connecting rod away from the slider. A positioning plate is fixedly connected to the lower end of the rotating shaft, and the positioning plate is fixedly connected to the insert block.

[0012] By setting a mechanical self-locking knob, turning the knob drives the lead screw to rotate, which in turn moves the slider back and forth, causing the connecting rod to unfold or close, and in turn, the insert block to move left and right. When the connecting rod unfolds, the insert block can be inserted into the slot, connecting the mounting block and the electronic tag OBU together. When the connecting rod closes, the insert block retracts into the mounting block and separates from the slot, allowing the mounting block and the electronic tag OBU to be separated and disassembled. The mechanical self-locking knob itself has a self-locking mechanism, such as a spring or gear, which locks itself when rotated to a certain angle, thus preventing the mounting block and the electronic tag OBU from rotating arbitrarily and causing them to separate after they are connected.

[0013] Furthermore, a guide rod is fixedly connected inside the mounting block, and a guide block is slidably connected outside the guide rod, with the guide block being fixedly connected to the slider.

[0014] Furthermore, a guide rod two is fixedly connected inside the mounting block, and a guide plate is slidably connected outside the guide rod two, with the guide plate being fixedly connected to the insert block.

[0015] Furthermore, the adhesive component includes an adhesive backing, which is adhered to the lower end of the mounting block, and an adhesive paper is adhered to the lower end of the adhesive backing.

[0016] Furthermore, a sensing module is fixedly connected to the lower left side of the electronic tag OBU body, and a solar photovoltaic panel is fixedly connected to the lower right side of the electronic tag OBU body.

[0017] Furthermore, a card slot is provided at the left end of the electronic tag OBU body, and a charging interface is fixedly connected to the front end of the electronic tag OBU body.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. By setting up the installation components, first insert the installation block into the installation slot, and at the same time push the trigger switch inward to press it firmly, so that the trigger switch and the micro switch installed on the built-in main board are connected. The micro switch detects whether the electronic tag OBU has been removed. When the trigger switch presses firmly against the micro switch, it has not been removed. When the trigger switch does not press firmly against the micro switch, the electronic tag OBU detects that it has been removed. Then, turn the mechanical self-locking knob, which will eventually drive the insertion block into the slot, thus completing the installation of the electronic tag OBU and the installation block. With this connection method, even if the adhesive backing of the installation block becomes loose from the windshield, it will not affect the tightness between the installation block and the electronic tag OBU, so that the trigger switch will not become loose and will not trigger the removal command. Therefore, the electronic tag OBU can still work normally even if the adhesive backing loses some of its stickiness.

[0020] 2. By setting a mechanical self-locking knob, rotating the knob drives the lead screw to rotate, which in turn drives the slider to move back and forth, thereby causing the connecting rod to unfold or close, and in turn causing the insert block to move left and right. When the connecting rod unfolds, the insert block can be inserted into the slot, connecting the mounting block and the electronic tag OBU together. When the connecting rod closes, the insert block retracts into the mounting block and separates from the slot, allowing the mounting block and the electronic tag OBU to be separated and disassembled. The mechanical self-locking knob itself has a self-locking mechanism, such as a spring or gear, which self-locks when rotated to a certain angle, thus preventing the mounting block and the electronic tag OBU from rotating arbitrarily and causing them to separate after they are connected.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0029] Reference Figure 1 As shown, an electronic tag OBU is provided in a preferred embodiment of the present invention, including an electronic tag OBU body 1, an installation component 2 connected to the lower end of the electronic tag OBU body 1, and an adhesive component 3 connected to the lower end of the installation component 2.

[0030] Reference Figures 1-5As shown, the mounting component 2 includes a mounting groove 201, which is located at the lower end of the electronic tag OBU body 1. Slots 202 are provided on the left and right sides of the inner wall of the mounting groove 201. A trigger switch 203 is movably connected to the bottom of the mounting groove 201. A mounting block 204 is movably connected inside the mounting groove 201. A pair of inserts 205 are slidably connected inside the mounting block 204. The pair of inserts 205 are symmetrically distributed on the left and right sides. The inserts 205 extend to the outside of the mounting block 204 and are movably inserted into the inside of the slots 202. The inserts 205 are adapted to the slots 202.

[0031] By setting up the installation component 2, the installation block 204 is first inserted into the installation slot 201, and the trigger switch 203 is pushed inward to press against it, so that the trigger switch 203 and the micro switch installed on the built-in main board are connected. The micro switch detects whether the electronic tag OBU has been removed. When the trigger switch 203 presses against the micro switch, it has not been removed. When the trigger switch 203 does not press against the micro switch, the electronic tag OBU detects that it has been removed. Then, the mechanical self-locking knob 206 is rotated, which finally drives the insert block 205 to be inserted into the slot 202, thereby completing the installation of the electronic tag OBU and the installation block 204. With this connection method, even if the adhesive 301 of the installation block 204 becomes loose from the windshield, it will not affect the tightness between the installation block 204 and the electronic tag OBU, so that the trigger switch 203 will not become loose and the removal command will not be triggered. Therefore, the electronic tag OBU can still work normally even if the adhesive 301 loses some of its stickiness.

[0032] Reference Figures 1-5 As shown, a mechanical self-locking knob 206 is rotatably connected to the front end of the mounting block 204, and a lead screw 207 is connected to the rear end of the mechanical self-locking knob 206. The lead screw 207 is rotatably connected to the mounting block 204, and a slider 208 is movably connected to the outside of the lead screw 207. The slider 208 is adapted to the lead screw 207.

[0033] Reference Figures 1-5 As shown, mounting plates 209 are fixedly connected to both ends of the slider 208. A connecting rod 210 is rotatably connected to the outside of the mounting plate 209. The connecting rod 210 is symmetrically distributed on the left and right. A rotating shaft 211 is rotatably connected to the end of the connecting rod 210 away from the slider 208. A positioning plate 212 is fixedly connected to the lower end of the rotating shaft 211. The positioning plate 212 is fixedly connected to the insert block 205.

[0034] By setting a mechanical self-locking knob 206, rotating the mechanical self-locking knob 206 drives the lead screw 207 to rotate, thereby driving the slider 208 to move back and forth, which in turn drives the connecting rod 210 to unfold or close, and in turn drives the insertion block 205 to move left and right. When the connecting rod 210 unfolds, the insertion block 205 can be inserted into the slot 202, connecting the mounting block 204 with the electronic tag OBU. When the connecting rod 210 closes, the insertion block 205 retracts into the mounting block 204 and separates from the slot 202, so that the mounting block 204 and the electronic tag OBU can be separated and disassembled. In addition, the mechanical self-locking knob 206 itself has a self-locking mechanism, such as a spring or gear, which can self-lock when rotated to a certain angle, so that the mounting block 204 and the electronic tag OBU will not rotate arbitrarily after being connected, causing them to separate.

[0035] Reference Figures 1-5 As shown, a guide rod 213 is fixedly connected inside the mounting block 204, and a guide block 214 is slidably connected outside the guide rod 213. The guide block 214 is fixedly connected to the slider 208.

[0036] By setting guide rod 213 and guide block 214, the slider 208 can be guided.

[0037] Reference Figures 1-5 As shown, a guide rod 215 is fixedly connected inside the mounting block 204, and a guide piece 216 is slidably connected outside the guide rod 215. The guide piece 216 is fixedly connected to the insert block 205.

[0038] By setting guide rod 215 and guide plate 216, the insertion block 205 can be guided, so that the insertion block 205 can only slide along guide rod 215.

[0039] Reference Figure 2 , Figure 3 and Figure 5 As shown, the adhesive component 3 includes an adhesive backing 301, which is attached to the lower end of the mounting block 204, and an adhesive backing paper 302 is attached to the lower end of the adhesive backing 301.

[0040] By setting up the adhesive component 3 and peeling off the adhesive backing paper 302, the mounting block 204 and the electronic tag OBU can be attached to the windshield of the vehicle using the adhesive backing 301.

[0041] Reference Figure 2 , Figure 3 and Figure 5 As shown, a sensing module 4 is fixedly connected to the lower left side of the electronic tag OBU body 1, and a solar photovoltaic panel 5 is fixedly connected to the lower right side of the electronic tag OBU body 1.

[0042] By setting up the sensing module 4, which works with the internally installed antenna, it can sense the ETC on the highway. The solar photovoltaic panel 5 converts solar energy into electrical energy and stores it in the battery inside the OBU to power the device.

[0043] Reference Figures 1-3 As shown, the left end of the electronic tag OBU body 1 is provided with a card slot 6, and the front end of the electronic tag OBU body 1 is fixedly connected with a charging interface 7.

[0044] Card slot 6 is used to insert CPC cards, and charging interface 7 is used to charge another battery inside the electronic tag OBU body 1.

[0045] Specific implementation process: During installation, first, insert the mounting block 204 into the mounting slot 201, and at the same time push the trigger switch 203 inward to press it firmly. Then, turn the mechanical self-locking knob 206 to drive the lead screw 207 to rotate, thereby driving the slider 208 to move back and forth, which in turn drives the connecting rod 210 to unfold or close, and then drives the insertion block 205 to move left and right. When the connecting rod 210 unfolds, the insertion block 205 can be inserted into the slot 202, connecting the mounting block 204 with the electronic tag OBU.

[0046] Finally, peel off the adhesive backing paper 302, and then use the adhesive backing paper 301 to stick the mounting block 204 and the electronic tag OBU onto the windshield of the vehicle.
