Detailed implementation manners:

[0014] The following further describes the present utility model with reference to the drawings, asFigure 1-2 As shown in the figure, the utility model includes a main frame body 1 formed by plastic injection molding. An installation seat 2 for a loading motor, a loading gear shaft 3 for installing a loading gear set, an installation seat 4 for a feeding motor, and a feeding gear shaft 5 for installing a feeding gear set are integrally injection molded on the main frame body 1. The loading motor installation seat 2 includes a loading motor mounting plate 21. A loading motor locking hole 22 and a loading motor output shaft through hole 23 are formed on the loading motor mounting plate 21. The feeding motor installation seat 4 includes a feeding motor mounting plate 41. A feeding motor locking hole 42 and a feeding motor output shaft through hole 43 are formed on the feeding motor mounting plate 41. Place the loading motor against the loading motor mounting plate 21 of the loading motor installation seat 2. Connect and fixedly install the loading motor on the loading motor mounting plate 21 of the loading motor installation seat 2 through a connecting member such as a fastening screw passing through the loading motor locking hole 22 on the loading motor mounting plate 21, and the output shaft of the loading motor passes through the loading motor output shaft through hole 23 to sleeve a worm and realize power output. Place the feeding motor against the feeding motor mounting plate 41 of the feeding motor installation seat 4. Connect and fixedly install the feeding motor on the feeding motor mounting plate 41 of the feeding motor installation seat 4 through a connecting member such as a fastening screw passing through the feeding motor locking hole 42 on the feeding motor mounting plate 41, and the output shaft of the feeding motor passes through the feeding motor output shaft through hole 43 to sleeve a worm and realize power output.

[0015] The loading motor is mainly used to control the loading and unloading of the disc. It supports the loading and unloading operations of the disc to ensure that the disc can correctly enter or exit the optical drive or other storage devices. The feeding motor is mainly responsible for the feeding movement of the optical disc, that is, the reading or writing operation of the optical disc in the optical drive. As key components of the in-vehicle DVD movement, compared with the past when assembling the in-vehicle DVD movement, it was necessary to first assemble the corresponding motor seat and gear shaft before installing the loading motor, feeding motor and the corresponding gear set. The utility model integrates the motor seat and gear shaft, eliminating the need for additional installation of the motor seat and gear shaft. It not only does not require separate procurement of the motor seat and gear shaft, can save connecting members such as fastening screws used in the installation process of the motor seat and gear shaft, and has fewer overall components, but also can eliminate processes such as spin riveting involved in the installation process of the motor seat and gear shaft. The entire assembly process is more convenient, which can reduce the overall production cost and improve the overall production and assembly efficiency.

[0016] A reinforcing rib 24 is provided between the loading motor mounting plate 21 and the main frame body 1. Through the reinforcing rib 24, the structural strength of the loading motor mounting plate 21 can be improved, so as to better ensure that the loading motor can work stably. ​

[0017] The loading motor mounting seat 2 further includes a full-bottom limiting groove 25 for the loading motor. By aligning and placing the bottom of the loading motor in the full-bottom limiting groove 25 of the loading motor, the bottom of the loading motor is limited by the full-bottom limiting groove 25, which can prevent the loading motor from running off track, further ensure the stable operation of the loading motor, and thus ensure the reliable loading and unloading of the disc.

[0018] The feeding motor mounting seat 4 further includes a rear-bottom limiting groove 44 for the feeding motor. By aligning and placing the rear end of the bottom of the feeding motor in the rear-bottom limiting groove 44 of the feeding motor, the rear end of the bottom of the feeding motor is limited by the rear-bottom limiting groove 44, which can prevent the feeding motor from running off track, further ensure the stable operation of the feeding motor, and thus ensure the high-precision reading and writing of the optical disc.

[0019] The feeding motor mounting seat 4 further includes two feeding motor limiting baffles 45, which are respectively arranged on both sides between the motor mounting plate and the rear-bottom limiting groove of the motor. The two feeding motor limiting baffles 45 can further enhance the limiting on both sides of the feeding motor and prevent the feeding motor from running off track, further ensure the continuous and reliable operation of the feeding motor, and thus further ensure the high-precision reading and writing of the optical disc.
