[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 This embodiment of a ground projection type road traffic signal guidance device includes a base plate 1 and a mounting plate 2. A housing 3 is fixed on the upper surface of the base plate 1. The mounting plate 2 is located above the housing 3. The mounting plate 2 is provided with a guidance mechanism 4 for projecting road signal guidance images onto the ground, so that vehicles can reach the designated place according to the road guidance. The housing 3 is provided with a lifting mechanism 5 for adjusting the projection height, which facilitates maintenance work and avoids pedestrians from damaging the projection equipment.

[0032] Please see Figure 2-3 To facilitate vehicles reaching designated locations based on road markings, the guiding mechanism 4 in this embodiment includes a mounting frame 41, a first adjusting member 42, a second adjusting member 43, a projector 44, and a protective member 45. The lower surface of the mounting frame 41 is rotatably connected to the upper surface of the mounting plate 2 via bearings. The first adjusting member 42 is disposed inside the mounting plate 2 and is used to adjust the projection angle laterally. The second adjusting member 43 is disposed on the mounting frame 41 and is used to adjust the projection angle longitudinally, thereby projecting the guiding image to the designated location according to the different installation positions. The projector 44 is fixed to the second adjusting member 43. The protective member 45 is disposed on the projector 44 and is used to protect the projector 44 to prevent the projected image from being affected.

[0033] In this embodiment, the first adjusting member 42 includes a first motor 421 and a first rotating rod 422. The first motor 421 is fixed to the inner bottom wall of the mounting plate 2. One end of the first rotating rod 422 is fixed to the output shaft of the first motor 421. The output shaft of the first motor 421 drives the first rotating rod 422 to rotate. The other end of the first rotating rod 422 passes through and extends to the upper side of the mounting plate 2 and is fixed to the lower surface of the mounting frame 41. The first rotating rod 422 drives the mounting frame 41 to rotate, thereby driving the projector 44 to rotate laterally and adjusting the lateral angle of the projector 44. The second adjusting member 43 includes a second motor 431, a second rotating rod 432, and a protective box 433. The second motor 431 is fixed to the front of the mounting frame 41. The output shaft of the second motor 431 is fixed to the outer side of the projector 44. The output shaft of the second motor 431 drives the projector 44 to rotate, thereby adjusting the longitudinal angle of the projector 44. The angle is adjusted so that the guiding image is projected at the designated position. One end of the second rotating rod 432 is fixed to the outside of the projector 44, and the other end of the second rotating rod 432 is rotatably connected to the rear inner wall of the mounting bracket 41 through a bearing. The rotation of the projector 44 drives the second rotating rod 432 to rotate, so that the projector 44 can maintain stability when rotating. The protective box 433 is fixed to the front of the mounting bracket 41. The second motor 431 is located inside the protective box 433. The protective box 433 protects the second motor 431 to prevent damage to the second motor 431. The protective component 45 includes a protective plate 451 and tempered glass 452. The protective plate 451 is fixed to the left side of the projector 44. The left side of the protective plate 451 has an installation port 453. The tempered glass 452 is fixed to the protective plate 451 through the installation port 453, which can ensure that the projector 44 can project images normally while protecting the lens of the projector 44.

[0034] Please see Figure 4 To facilitate maintenance and prevent pedestrians from damaging the projection equipment, the lifting mechanism 5 in this embodiment includes a drive component 51, a transmission component 52, a threaded sleeve 53, and a guide component 54. The drive component 51 is mounted on the housing 3 and is used to drive the transmission component 52. The transmission component 52 is mounted on the housing 3. The threaded sleeve 53 is threadedly connected to the transmission component 52 and is used to lift the threaded sleeve 53. Since the projector 44 needs to be protected from damage by pedestrians or changes in the projection angle of the projector 44 during normal operation, the projector 44 needs to be raised to a height that is beyond the reach of pedestrians. The guide component 54 is located inside the housing 3 and is used to guide and limit the threaded sleeve 53 to prevent it from being affected and shifting during lifting. The top end of the threaded sleeve 53 extends through and to the upper side of the housing 3 and is fixed to the lower surface of the mounting plate 2.

[0035] In this embodiment, the driving component 51 includes a third motor 511 and a third rotating rod 512. The third motor 511 is fixed to the inner top wall of the housing 3. One end of the third rotating rod 512 is fixed to the output shaft of the third motor 511. The output shaft of the third motor 511 drives the third rotating rod 512. The transmission component 52 includes a driving gear 521, a driven gear 522, and a threaded rod 523. The driving gear 521 is fixed to the end of the third rotating rod 512 away from the third motor 511. The third rotating rod 512 drives the driving gear 521 to rotate. The driven gear 522 is fixed to the outer side of the threaded rod 523, and the driven gear 522 is connected to the driving gear 521 in a transmission connection. The driving gear 521 drives the driven gear 522 to rotate, and the driven gear 522 drives the threaded rod 523 to rotate. One end of the threaded rod 523 is rotatably connected to the inner bottom wall of the housing 3 through a bearing. The outer side of the threaded rod 523 is threadedly connected to the inner side of the threaded sleeve 53. The rotation of the threaded rod 523 drives the threaded sleeve 53 to move, and the threaded sleeve 53 drives the mounting plate 2 to move, thereby allowing the projector 44 to be lowered for maintenance. After maintenance, the projector 44 can be raised back to its original height, improving work efficiency. The guide component 54 includes two guide rods 541 and a guide plate 542. The two ends of the two guide rods 541 are fixed to the upper and lower inner walls of the chassis 3 respectively, and are symmetrically distributed on the left and right sides of the central axis of the chassis 3. The guide plate 542 is slidably connected to the outer side of the two guide rods 541. The inner side of the guide plate 542 is fixed to the outer side of the threaded sleeve 53. The movement of the threaded sleeve 53 drives the movement of the guide plate 542. The guide plate 542 slides on the guide rod 541, thereby limiting the movement trajectory and angle of the threaded sleeve 53 and preventing the threaded sleeve 53 from deviating.

[0036] The working principle of the above embodiments is as follows:

[0037] (1) First, a suitable location needs to be selected on both sides of the road to install the device, so that the base plate 1 is fixed on the ground. Since the installation location varies, after the device is installed, the angle of the projector 44 needs to be adjusted so that the traffic signal guidance image can be accurately projected to the position that the driver can see. First, raise the projector 44 to a certain height to prevent pedestrians from touching the projector 44. Then turn on the first motor 421. The output shaft of the first motor 421 drives the first rotating rod 422 to rotate. The first rotating rod 422 drives the mounting frame 41 to rotate, thereby driving the projector 44 to rotate laterally. After adjusting the lateral angle of the projector 44, turn on the second motor 431. The output shaft of the second motor 431 drives the projector 44 to rotate, thereby adjusting the longitudinal angle of the projector 44 so that the guidance image is projected at the designated position.

[0038] (2) Since the projector 44 needs to be protected from damage or changes in the projection angle by pedestrians when it is working normally, the projector 44 needs to be raised to a height that is beyond the reach of pedestrians. When the projector 44 is being repaired, it needs to be lowered and the third motor 511 is turned on. The output shaft of the third motor 511 drives the third rotating rod 512 to rotate. The third rotating rod 512 drives the drive gear 521 to rotate. The drive gear 521 drives the driven gear 522 to rotate. The driven gear 522 drives the threaded rod 523 to rotate. The rotation of the threaded rod 523 drives the threaded sleeve 53 to move. The threaded sleeve 53 drives the mounting plate 2 to move, so that the projector 44 can be lowered for repair. After the repair is completed, the projector 44 is raised back to its original height to improve work efficiency.
