Technical field

The present disclosure relates to the technical field of electronic products, and in particular to a drive system and terminal equipment.

Background technique

High-screen-to-body ratio terminal devices are favored by major terminal equipment manufacturers due to their good visual experience. In order to achieve the largest possible screen-to-body ratio, the earpieces used in related technologies often use an exciter to drive the screen to achieve sound, and the optical module including multiple optical devices needs to be hidden in the top area of the terminal device through a screw Thread and sliding block structure realize up and down telescopic movement. However, when the screw thread and the hook in the slider structure in the related art exert a force on one side of the optical module, it will cause the optical module to be unevenly moved up and down, which is prone to jamming. At the same time, the screw thread and the slider The overall structure occupies a relatively large space, leading to the problem of tight stacking space.

FIG. 1 is a schematic diagram of the layout of a screw thread type up and down telescopic optical module in the whole machine in the related art. 101 is a motor, used to provide rotational power; 102 is a gearbox, used to decelerate to increase output torque while reducing the inertia of the load; 103 is a hanging table, which is connected to the slider module 107 with an optical module, where The force exerted by the suspension platform 103 acts on one side of the slider module 107, so there will be uneven forces on the left and right sides; 104 is a screw thread structure, when the motor 101 rotates, the output through the reduction box 102 is higher The torque moves in the Y direction of the screw thread structure 104; 105 is the screw rod to prevent the motor 101, the reduction box 102 and the hanging table 103 from rotating left and right; 106 is the main board; 108 is the compression spring to protect the slider module 107 keeps working normally after being subjected to external forces; 109 is a polyoxymethylene (POM) guide block to ensure that the slider module 107 slides better in the Y direction, where the Y direction is the length direction of the terminal device .

As shown in Fig. 2, the motor 101, the reduction box 102 and the suspension platform 103 move upward under the drive of the screw thread structure 104. The suspension platform 103 exerts a force on one side of the slider module 107 to drive the slider module 107 to move upward. Due to the uneven forces on the left and right sides of the slider module 107, the slider module 107 will tilt during the movement, which is prone to jamming. At the same time, the screw thread structure 104 and the slider module 107 occupies a relatively large space in the whole machine, resulting in tight stacking space.
