[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model facilitates the quick fixing and installation of the reading lamp base structure through the installed suction cup and piston block. After placing the automotive reading lamp inside the base body, the reading lamp is closely attached to the suction cup. Then, the driving component works to adjust the position of the piston block. When the piston block moves, the air inside the negative pressure groove is extracted through the square groove and the air extraction pipe, thereby generating negative pressure inside the negative pressure groove and causing the suction cup to generate suction.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1 、 Figure 2 and Figure 3 For a reading lamp base structure, it includes a base body 1. There are positioning holes 2 provided on the base body 1. Three groups of negative pressure grooves 3 are inlaid inside the base body 1. There are suction cups 4 provided on the negative pressure grooves 3, and the negative pressure grooves 3 are communicated with the suction cups 4. There is a square groove 5 provided inside the base body 1. There is a piston block 7 provided inside the square groove 5. There is a driving component provided inside the square groove 5. There is an air extraction pipe 6 provided on the square groove 5, and the air extraction pipe 6 is communicated with the negative pressure grooves 3. When using the reading lamp base structure to install and fix an automotive reading lamp, first use bolts to fix the base body 1 at the installation location through the positioning holes 2. After placing the automotive reading lamp inside the base body 1, make the reading lamp closely fit with the suction cups 4. Make the driving component work to adjust the position of the piston block 7. When the piston block 7 moves, the air inside the negative pressure grooves 3 will be extracted through the square groove 5 and the air extraction pipe 6, thereby generating negative pressure inside the negative pressure grooves 3 and causing the suction cups 4 to generate suction force. After the suction cups 4 generate suction force at the joint with the reading lamp, the position of the reading lamp will be limited, achieving the purpose of quickly limiting the position of the reading lamp and improving the installation efficiency.

[0021] Please refer to Figure 2 For the driving component, it includes a threaded cylinder 8, a threaded rod 9 and a driving motor 10. The threaded cylinder 8 is fixedly installed on the piston block 7. The threaded rod 9 is threadedly connected inside the threaded cylinder 8. The driving motor 10 is fixedly installed inside the square groove 5, and one end of the threaded rod 9 is fixedly connected to the output end of the driving motor 10. When the driving component works, make the driving motor 10 electrically connected to the vehicle-mounted power supply. The driving motor 10 is a remote control motor, and the operation of the driving motor 10 can be controlled. When the driving motor 10 works, it will drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 will cause the position of the threaded cylinder 8 to move. Furthermore, when the threaded cylinder 8 moves, it will pull the piston block 7 to move. The movement of the piston block 7 will cooperate with the square groove 5 and the air extraction pipe 6 to extract the air inside the negative pressure grooves 3.

[0022] Please refer to Figure 2 and Figure 3 For the square groove 5, there is an air delivery pipe 11 provided on it. When the piston block 7 moves, the air on the other side of the piston block 7 will be compressed, and the compressed air will flow into the sealing groove 12 through the air delivery pipe 11.

[0023] Please refer to Figure 1 and Figure 3, symmetrically arranged sealing grooves 12 are provided inside the base body 1. A clamping block 13 is arranged inside the sealing groove 12, and a sealing ring is arranged around the clamping block 13 for sealing the gap between the sealing groove 12 and the clamping block 13. The outer wall of the clamping block 13 fits against the inner wall of the sealing groove 12. After the air compressed by the movement of the piston block 7 enters the sealing groove 12, it will push the clamping block 13 to move. A clamping groove corresponding to the clamping block 13 is provided on the reading lamp. After the clamping block 13 moves into the clamping groove, the stability of the installation of the reading lamp will be improved.

[0024] Please refer to Figure 3 , a limiting ring 14 is fixedly installed inside the sealing groove 12. A limiting rod 15 passes through the limiting ring 14, and one end of the limiting rod 15 is fixedly connected to the outer wall of the clamping block 13. The sealing groove 12 provides an installation space for the limiting ring 14. When the clamping block 13 moves, the cooperation between the limiting rod 15 and the limiting ring 14 will guide and limit the clamping block 13.

[0025] Please refer to Figure 3 , a return spring 16 is installed around the limiting rod 15, and one end of the return spring 16 is fixedly connected to one end of the limiting rod 15. When the output end of the driving motor 10 rotates in the reverse direction to reset the piston block 7, the reset of the return spring 16 will push the limiting rod 15 to move, and then drive the clamping block 13 to reset.

[0026] Working principle: First, when using the reading lamp base structure to install and fix the car reading lamp, first use bolts to fix the base body 1 through the positioning holes 2 at the installation location. After placing the car reading lamp inside the base body 1, make the reading lamp fit tightly with the suction cup 4. Connect the driving motor 10 to the vehicle-mounted power supply. The driving motor 10 is a remote control motor, and the operation of the driving motor 10 can be controlled. When the driving motor 10 operates, it will drive the threaded rod 9 to rotate. The rotation of the threaded rod 9 will cause the position of the threaded barrel 8 to move. Then, when the threaded barrel 8 moves, it will pull the piston block 7 to move. The movement of the piston block 7 will extract the air inside the negative pressure groove 3 through the cooperation of the square groove 5 and the air extraction pipe 6, generating negative pressure inside the negative pressure groove 3 and causing the suction cup 4 to generate suction. After the suction cup 4 generates suction at the joint with the reading lamp, it will limit the position of the reading lamp, achieving the purpose of quickly limiting the position of the reading lamp. When the piston block 7 moves, it will compress the air on the other side of the piston block 7. The compressed air will flow into the sealing groove 12 through the delivery pipe 11. After the air compressed by the movement of the piston block 7 enters the sealing groove 12, it will push the clamping block 13 to move. A clamping groove corresponding to the clamping block 13 is provided on the reading lamp. After the clamping block 13 moves into the clamping groove, the stability of the installation of the reading lamp will be improved.
