[0019] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a roof billboard display rack, including a triangular hollow back seat 1 and triangular stands 2 fixed on the outer walls on both sides of the triangular hollow back seat 1, and a downwardly extending lower cutting groove 201 is provided at the top of the triangular stand 2. A U-shaped display rack 3 is rotatably installed between the two lower cutting grooves 201. The triangular hollow back seat 1 and the triangular stands 2 are made of components of hard plastic material. The staff takes out the display rack and transports it to the top of the vehicle luggage rack. The hard plastic material usually has the characteristic of light weight, so that the overall weight of the triangular hollow back seat 1 and the triangular stands 2 is relatively light, which helps to reduce the burden on the vehicle structure by the billboard display rack;

[0020] On the outer wall of one side of the U-shaped display rack 3, a single advertising board 4 is fixed. On both sides inside the triangular hollow backrest 1, support rods 501 are slidably installed. The top ends of the support rods 501 penetrate to the outside of the triangular hollow backrest 1 and are fixed with vehicle frame arms 5. Inside the triangular hollow backrest 1, a two-way distance adjustment component 7 for driving the two vehicle frame arms 5 to move towards each other in the X-axis direction is installed. The vehicle frame arms 5 are fixed to the vehicle luggage rack by bolting, thus completing the installation work of the display rack. Through the adjustable vehicle frame arms 5, the advertising board display rack can be adjusted and fixed according to the sizes and shapes of different vehicles;

[0021] On both sides of the back of the U-shaped display rack 3, residual tooth pieces 301 are integrally formed. The surface of the residual tooth pieces 301 is provided with fan-shaped hollow parts. Inside the triangular stand 2, a worm and gear transmission unit 202 for driving the residual tooth pieces 301 to rotate is provided;

[0022] The two-way distance adjustment component 7 includes a cavity 6 provided inside the triangular hollow backrest 1, and a bevel gear transmission structure 702 rotatably installed inside the cavity 6. Nut pairs 704 are installed at both ends of the threaded part on the surface of the bevel gear transmission structure 702. One end of the nut pair 704 is fixedly connected to one end of the support rod 501. The two-way distance adjustment component 7 further includes a knob 701 installed on one side of the surface of the triangular hollow backrest 1. One end of the knob 701 extends into the cavity 6 and is installed with a two-way lead screw 703 for driving the bevel gear transmission structure 702 to rotate;

[0023] The staff rotates the bevel gear transmission structure 702 by the knob 701 and the two-way lead screw 703. Then the bevel gear transmission structure 702 drives the nut pair 704 to move. The nut pair 704 pushes the support rod 501 to slide out of the triangular hollow backrest 1, thereby adjusting the distance between the two vehicle frame arms 5 in the X-axis direction. The vehicle frame arms 5 are combined with the vehicle luggage rack. The advertising board display rack can rely on the stability of the vehicle luggage rack to ensure that the advertising board does not shake or fall off during driving;

[0024] The worm and gear transmission unit 202 includes a motor installed on one side inside the triangular stand 2, and a worm and gear transmission structure installed at the output end of the motor. One end inside the lower cutting groove 201 is rotatably installed with a short shaft 203. One end of the short shaft 203 is fixed with a driving gear 204. The driving gear 204 and the residual tooth piece 301 are meshed with each other. The other end of the short shaft 203 is connected to the output end of the worm and gear transmission unit 202 through the worm and gear transmission structure. The staff starts the worm and gear transmission unit 202 in the triangular stand 2 to work. The worm and gear transmission unit 202 drives the short shaft 203 and the driving gear 204 to rotate. At this time, the driving gear 204 drives the residual tooth piece 301 and the U-shaped display rack 3 to flip, realizing the functions of standing up and placing the single advertising board 4 in parallel;

[0025] When it is necessary to turn the single billboard 4 upright, the rotational power of the worm and worm gear drive unit 202 is transmitted to the short shaft 203 and the driving gear 204. The driving gear 204 drives the broken tooth piece 301 and the U-shaped display rack 3 to turn. The worm and worm gear drive unit 202 has the characteristic of stable transmission, which can ensure the smooth movement of the billboard during the rotation and erection process without bumps.

[0026] The self-locking property of the worm and worm gear drive unit 202 can keep the single billboard 4 and the U-shaped display rack 3 in a stable state after rotation and erection. Especially in the case of strong wind, the stable load-bearing capacity helps to improve the safety and reliability of the billboard.

[0027] When the embodiment of the present application is in use, first, the staff takes out the display rack and transports it to the top of the vehicle luggage rack. Then, the staff controls the two vehicle frame arms 5 in the X-axis direction to move towards each other through the bidirectional distance adjustment component 7, that is, the two vehicle frame arms 5 move away from or close to each other until the two vehicle frame arms 5 clamp the two side walls of the vehicle luggage rack. Then, the vehicle frame arms 5 are fixed to the vehicle luggage rack by bolting, thus completing the installation of the display rack. Through the adjustable vehicle frame arms 5, the billboard display rack can be adjusted and fixed according to the sizes and shapes of different vehicles. At this time, the length extension direction of the single billboard 4 is parallel to the vehicle length direction. Then, the staff starts the worm and worm gear drive unit 202 in the triangular stand 2 to work. The worm and worm gear drive unit 202 drives the short shaft 203 and the driving gear 204 to rotate. At this time, the driving gear 204 drives the broken tooth piece 301 and the U-shaped display rack 3 to turn, realizing the functions of erecting and horizontally placing the single billboard 4. During this process, through rotation, lifting and horizontal placement, the length of the billboard can be parallel to the vehicle length direction, thereby achieving a larger advertising display area, providing more space to display creativity and information, and making the advertising content more prominent and eye-catching.
