The driving circular gear 71 and the first driven circular gear 72 are firstly matched by transmission. The inner cavity of the first driven circular gear 72 is fixedly connected to a reciprocating screw rod 73 that rotates with the front frame 3, and a screw rod sleeve 74 is threadedly connected to the reciprocating screw rod 73.

[0054] like Figure 14-16As shown, during the warning and guidance of traffic on congested roads, the traffic police department personnel mostly blow whistles to guide and evacuate the traffic on the congested roads. Not only is the work intensity high, but the guidance effect is also poor. It is not possible to perform effective and continuous guidance and evacuation operations on the traffic on the congested roads in the form of mechanical bells. Both sides of the inner cavity of the rear frame 4 are provided with sound collecting cavities and a bell assembly 8, and the bell assembly 8 includes a second driven circular gear 81 meshed with the back of the driving circular gear 71, and the top of the second driven circular gear 81 is fixedly connected to the main bevel gear 82 through a fixing rod, and the back of the main bevel gear 82 is meshed with a secondary bevel gear 83. The driving circular gear 71 first drives the main bevel gear 82 to rotate through the second driven circular gear 81, and the main bevel gear 82 drives the secondary bevel gear 83 to rotate accordingly;

Transverse guide rails 89 are provided on the upper and lower sides of the center of the inner cavity of the rear frame 4, and the inner cavity of the transverse guide rails 89 is slidably connected to a guide rail block 810 fixedly matched with the moving frame 85, which serves as a sliding support for the moving frame 85 and improves the stability of the back and forth displacement of the moving frame 85.

[0056] The working principle of the road warning and guidance device for driving safety in traffic congestion sections is as follows: the solar panel 19 converts solar energy into electrical energy to power the electrical components, and according to the actual guidance needs of driving in the congested section, the first electric push rod 52 is first controlled to open and the driving bevel gear 53 is moved down to the meshing part of the bevel gear frame 54, and then the double-headed motor 51 is controlled to open and drive the bevel gear frame 54 to rotate forward and reverse through the driving bevel gear 53 that is meshed in place, and the other end gear of the bevel gear frame 54 drives the driven bevel gear 55 to rotate accordingly, and the driven bevel gear 55 drives the driving wheel frame 56 to rotate forward and reverse, and the driven wheel frame 57 and the auxiliary wheel frame 58 assist the underframe 1 in moving. After the driving wheel frame 56 drives the underframe 1 to move to the required guiding position through the driven wheel frame 57 and the auxiliary wheel frame 58, the double-headed motor 51 is first controlled to pause, and then the first electric push rod 52 is controlled to close and the driving bevel gear 53 is moved up to the meshing part of the bevel gear frame 54 to the initial position;

[0057] After the chassis 1 is maneuvered into position, the second electric push rod 61 is first controlled to open and drive the locking head 62 to move up to the clamping part of the locking seat 63, and then the double-headed motor 51 is controlled to reopen and drive the threaded rod 64 to rotate forward and reversely through the locking head 62 and the locking seat 63 that are clamped in place. The threaded rod 64 drives the two groups of brackets 66 on the threaded sleeve 65 to move up and down accordingly. The two groups of brackets 66 drive the display screen 68, the wireless camera 9 and the laser 10 to move up and down accordingly through the two support rods 67 until the display screen 68, the wireless camera 9 and the laser 10 are adjusted to a predetermined height, and the driving on the congested road section is guided by the text display on the display screen 68. At the same time, the wireless camera 9 also takes pictures of the driving scene on the congested road section. At night or in heavy fog, the laser 10 irradiates the space above the driving on the congested road section with laser guidance to prevent the vehicle from deviating from the driving route.

[0058] After the height of the display screen 68, the wireless camera 9 and the laser 10 are adjusted to the right position, the double-headed motor 51 is first controlled to pause, and then the second electric push rod 61 is controlled to close and drive the locking head 62 to move down and disengage from the clamping part of the locking seat 63 to the initial position, and then the double-headed motor 51 is restarted to drive the driving circular gear 71 to rotate. At this time, the driving bevel gear 53 on the first electric push rod 52 and the locking head 62 on the second electric push rod 61 are both in an idling state, and the driving circular gear 71 drives the reciprocating screw rod 73 on the first driven circular gear 72 to rotate, and the reciprocating screw rod 73 drives the double-sided gear rack 75 on the screw rod sleeve 74 to move back and forth accordingly. The double-sided gear rack 75 that reciprocates up and down drives the two sets of transfer circular gears 76 to rotate at a forward and reverse frequency, and the two sets of transfer circular gears 76 drive the warning light groups 78 on the two sets of support arms 77 to swing back and forth. The two sets of warning light groups 78 that swing back and forth provide dynamic warnings for driving on congested roads;

[0059] During this period, the driving circular gear 71 drives the first driven circular gear 72 to rotate, and also drives the second driven circular gear 81 to rotate. The second driven circular gear 81 drives the secondary bevel gear 83 on the main bevel gear 82 to rotate accordingly. The secondary bevel gear 83 drives the moving frame 85 on the cam frame 84 to move back and forth. The moving frame 85 drives the two groups of knocking heads 86 to alternately knock the two groups of metal reeds 87 back and forth. The two groups of metal reeds 87 produce sound in the two groups of sound collecting cavities of the rear frame 4. The sound generated in the two groups of sound collecting cavities is then amplified and propagated through two groups of loudspeakers 88, which rings a warning bell for driving on congested roads to prevent drivers from changing lanes and cutting in line at random and causing traffic accidents.

[0060] It should be noted that the specific models and specifications of the double-headed motor 51, the first electric push rod 52 and the second electric push rod 61 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0061] The power supply circuits of the double-headed motor 51, the first electric push rod 52 and the second electric push rod 61, the warning light group 78, the loudspeaker 88, the wireless camera 9 and the laser 10 are clear to those skilled in the art and will not be described in detail here.
