[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic structural diagram of a preferred embodiment of a vehicle identification device with a protective effect provided by the utility model; Figure 2 This is a schematic diagram of the connection between the dust removal block and the transmission block of the utility model; Figure 3 It is a three-dimensional diagram of the structure of the utility model; Figure 4 The figure is a schematic diagram of the internal structure of the vertical block of the utility model. A vehicle identification device with a protective effect comprises a base 1, a support column 2 is fixed on the top of the base 1, a mounting frame 3 is arranged on the top of the support column 2, a display screen 4 is arranged on the front of the mounting frame 3, a camera body 5 is arranged on the top of the mounting frame 3, and a dust removal mechanism is arranged on the front of the mounting frame 3. The dust removal mechanism is used to clean the dust on the surface of the display screen 4; the dust removal mechanism comprises two vertical blocks 301 fixed on the front of the mounting frame 3, a dust removal block 302 is arranged between the two vertical blocks 301, a motor 303 is arranged on the outside of the vertical block 301, and the output end of the motor 303 is fixedly connected to the sensor. The driving shaft 304 has a first chamber 305 formed inside the vertical block 301. The transmission shaft 304 extends to the outside of the first chamber 305 and a gear 306 is fixed thereto. A rack 307 is meshed on one side of the gear 306. The bottom end of the rack 307 is inserted into a first insertion hole 308 formed in the vertical block 301. A transmission block 309 is fixedly connected to the first chamber 305 and located on the other side of the rack 307. The transmission block 309 is slidably connected to a first slide groove 310 formed in the vertical block 301. One end of the transmission block 309 extends out of the first slide groove 310 and is connected to one side of the dust removal block 302.

[0021] Through the above technical solution, the motor 303 is externally connected to a power source, and the two motors 303 outside the two vertical blocks 301 are started. The motor 303 drives the transmission shaft 304 and the gear 306 in the first chamber 305 to rotate clockwise, while the gear 306 in the other vertical block 301 rotates counterclockwise. The rotation of the two gears 306 drives the two racks 307 to move downward, and the racks 307 drive the transmission block 309 and the dust removal block 302 to move downward, so that the dust removal block 302 cleans the dust on the display screen 4 to prevent the dust from corroding the screen of the display screen 4 for a long time, so that the protection effect of the display screen 4 is higher.

[0022] Reference Figure 4 A limit plate 311 is fixedly connected inside the first chamber 305 and at the top of the rack 307. A horizontal plate 312 is fixed inside the first chamber 305. A sliding rod 313 is fixedly connected to the top of the horizontal plate 312. The top of the sliding rod 313 is fixedly connected to the top wall of the first chamber 305, and the limit plate 311 is slidably connected to the sliding rod 313.

[0023] Through the above technical solution, when the rack 307 moves up and down, the limit plate 311 at its top slides up and down on the slide rod 313. Through the cooperation between the limit plate 311 and the slide rod 313, the rack 307 has higher stability during the up and down movement.

[0024] Reference Figure 1 and Figure 2 A movable groove 314 is provided inside the transmission block 309, and a spring 315 is fixedly connected to the inner wall of the movable groove 314. The other end of the spring 315 is fixedly connected to an extrusion plate 316. The extrusion plate 316 is fixedly connected to a fixed rod 317 on the side away from the spring 315. The fixed rod 317 extends out of the movable groove 314 and is inserted into the fixed groove 318 provided in the dust removal block 302. A baffle 319 is provided inside the movable groove 314 and on the outer side of the fixed rod 317. The outer side of the baffle 319 is fixed to the inner wall of the movable groove 314. Fixed connection, a second chamber 320 is opened inside the dust removing block 302, and a push rod 321 is arranged inside the second chamber 320. One end of the push rod 321 is inserted into the second socket 322 opened in the dust removing block 302, and the other end of the push rod 321 is fixedly connected to a translation block 323, and a connecting block 324 is fixedly connected to the top of the translation block 323. The connecting block 324 is slidably connected to the second slide groove 325 opened in the dust removing block 302, and the connecting block 324 extends out of the second slide groove 325 and is fixedly connected to the top of a push plate 326.

[0025] Through the above technical solution, the push plate 326 is moved to the left, and the connecting block 324 and the translation block 323 in the second chamber 320 are driven to move synchronously through the push plate 326. The translation block 323 drives the push rod 321 to move to the left, so that the push rod 321 squeezes the fixed rod 317 in the fixed groove 318, so that the fixed rod 317 is separated from the fixed groove 318 and enters the movable groove 314. Similarly, the other fixed rod 317 can be adjusted to the right to release the restriction of the two fixed rods 317 on the dust removal block 302, so as to facilitate the disassembly and replacement of the dust removal block 302 that has been used for a long time.

[0026] Reference Figure 2 Two guide rods 327 symmetrically distributed up and down are fixed inside the second chamber 320, and the translation block 323 is slidably connected to the guide rods 327. By providing two guide rods 327, the translation block 323 can move left and right in the second chamber 320 more smoothly.

[0027] Reference Figure 1 and Figure 3 The support column 2 includes a first column 201 and a second column 202. The first column 201 is fixed on the base 1, and the second column 202 is fixed on the bottom of the mounting frame 3. The bottom of the second column 202 is fixedly connected with an insertion rod 203, and the insertion rod 203 is inserted into a slot 204 opened in the first column 201. A threaded fastening cap 205 is sleeved on the outside of the first column 201. The threaded fastening cap 205 extends out of the inner wall of the first column 201 and is screwed to the outer wall of the second column 202.

[0028] Through the above technical solution, the second column 202 is pulled upward so that the second column 202 drives the insertion rod 203 in the slot 204 to move upward. When adjusted to the specified height, the threaded fastening cap 205 is rotated to make the threaded fastening cap 205 move upward to the outside of the second column 202. The first column 201 and the second column 202 are fixed together by the threaded fastening cap 205 to prevent the second column 202 from sliding down. The use height of the display screen 4 and the camera body 5 can be adjusted by adjusting the second column 202, thereby improving the practicality of the display screen 4 and the camera body 5.

[0029] The implementation principle of a vehicle identification device with a protective effect in an embodiment of the utility model is as follows: by adopting a dust removal mechanism, the two motors 303 on the outer sides of the two vertical blocks 301 are started, and the motor 303 drives the transmission shaft 304 and the gear 306 in the first chamber 305 to rotate clockwise, while the gear 306 in the other vertical block 301 rotates counterclockwise, and the two racks 307 are driven to move downward by the rotation of the two gears 306, and the transmission block 309 and the dust removal block 302 are driven to move downward by the rack 307, so that the dust removal block 302 cleans the dust on the display screen 4 to prevent the dust from corroding the screen of the display screen 4 for a long time, so that the protection effect of the display screen 4 is higher.
