The worm gear structure 32 includes a worm and a worm wheel meshing with the worm. The worm is connected to the rotating shaft of the motor 31, and the worm wheel meshes with the lead screw through meshing teeth. When the motor 31 is started, the motor 31 drives the worm to rotate. The worm wheel rotates under the action of the worm and moves along the meshing teeth on the lead screw 40, generating displacement, and driving the storage box 20 to move at the same time. In other words, the rotation of the worm gear mechanism 32 can be controlled by the motor 31, and the worm gear mechanism 32 can be moved relative to the lead screw 40, thereby realizing the adjustment of the position of the storage box 20. In addition, the self-locking function of the worm gear mechanism 32 is used to start and stop the worm gear mechanism 32, thereby controlling the movement and stop of the storage box 20, and further realizing the adjustment of the storage box 20 to any position on the base.
[0026] The vehicle-mounted movable storage system also includes a sliding mechanism 50, which is arranged at the bottom of the storage box 20 and is slidably connected to the base 10, that is, the sliding mechanism is arranged between the storage box 20 and the base 10, and is fixedly connected to the storage box and slidably connected to the base. Of course, the sliding mechanism can also be an integrated structure with the storage box. The worm gear mechanism is connected to the sliding mechanism. Specifically, a slide rail or a slide groove for the sliding mechanism to slide is provided on the base 10. The sliding mechanism is fixed to the bottom of the storage box 20. When the switch is turned on, the motor 31 rotates and drives the worm gear mechanism 32 to move along the screw 40. The worm gear mechanism drives the sliding mechanism, and the sliding mechanism drives the storage box 20 to slide on the base 10.
[0027] In a specific embodiment, the sliding mechanism 50 includes a sliding seat 51 and a sliding part 52, the sliding seat 51 is fixedly connected to the storage box 20, the sliding part 52 is connected to the sliding seat 51, the worm gear mechanism is connected to the sliding part, one end of the rotating shaft of the worm is connected to the rotating shaft of the motor, and the other end is connected to the sliding part, optionally, the sliding part is provided with a receiving chamber, the worm gear mechanism is accommodated in the receiving chamber, one end of the rotating shaft of the worm is connected to the bottom wall of the receiving chamber, the worm wheel is meshed with the lead screw, the lead screw passes through the opposite side walls of the receiving chamber, when the motor is started and the worm gear mechanism is driven to rotate, the worm gear mechanism is displaced along the lead screw, and at the same time, the sliding part is driven to slide on the base, thereby realizing the position adjustment of the storage box. A slide groove 11 is provided on the base 10, and the sliding part 52 is accommodated in the slide groove 11 and slides along the slide groove 11. It should be understood that the sliding seat 51 can be fixedly connected to the bottom of the storage box 20, or it can be an integrated structure with the bottom of the storage box 20, and the specific form is not limited.
[0028] In a specific embodiment, a first limiting portion 53 is provided at the connection between the sliding portion 52 and the sliding seat 51, and the first limiting portion 53 is partially accommodated in the slide groove 11. That is, there is a connection portion between the sliding portion 52 and the sliding seat 51, and the connection portion is provided with a first limiting portion 53, and the first limiting portion 53 is partially accommodated in the slide groove 11, and the side surface of the first limiting portion 53 is against the two sides of the slide groove 11. When the sliding portion 52 slides in the slide groove 11 of the base 10, the first limiting portion 53 limits the sliding portion 52 to ensure that the sliding portion 52 slides in a straight line in the slide groove 11. Specifically, the first limiting portion 53 includes a first part and a second part arranged on opposite sides of the connection portion, and the side surfaces of the first part and the second part are against the two side edges of the slide groove opening, and the first part and the second part both have a first end accommodated in the slide groove and a second end located outside the slide groove. When the sliding portion 52 slides in the slide groove, the first limiting portion is against the two side edges of the slide groove to ensure that the sliding portion slides in a straight line in the slide groove. Preferably, the side surfaces of the first part and the second part of the first limiting portion are curved surfaces, and the thickness of the first end located in the slide groove is greater than the thickness of the second end located outside the slide groove, so that the sliding part is stably maintained in the slide groove and will not fall out of the slide groove.
[0029] In a specific embodiment, referring to Figure 4 and Figure 5 The sliding part 52 includes a fixing part 521 and a first roller 522. The fixing part 521 is connected to the sliding seat 51. The first roller 522 is accommodated in the slide groove 11 and presses against the bottom wall of the slide groove 11 to slide along the slide groove 11. Specifically, the motor 31 is arranged inside the storage box 20. One end of the worm gear mechanism 32 is connected to the rotating shaft of the motor 31, and the other end is fixedly connected to the fixing part 521. When the motor 31 is started, the worm gear mechanism 32 is driven to move along the screw 40. At the same time, the worm gear mechanism 32 drives the sliding mechanism 50 and links the storage box 20 to slide in the slide groove 11 of the base; and the worm gear mechanism 32 is locked at any position on the screw 40 through the self-locking function of the worm gear mechanism 32, so that the storage box 20 is stopped at any position. Optionally, the sliding part includes four groups of first rollers, each group of first rollers includes two rollers, the fixing part is provided with a limiting groove, and the rotating shaft of each group of first rollers is installed on the side wall of the limiting groove, one of the rollers is accommodated in the limiting groove, and the other roller is located outside the limiting groove, thereby ensuring that the direction of the roller is fixed when sliding.
[0030] In a specific embodiment, referring to Figure 6 and Figure 7The sliding portion 52 also includes a second limiting portion 54 connected to the fixed portion 521, and the second limiting portion 54 includes a second roller 541, a rocker 542, and a preload spring 543. The second roller 541 is connected to the fixed portion 521 through a rotating shaft, and the second roller 541 abuts against the top wall of the slide groove 11 and slides along the top wall of the slide groove 11. The rocker 542 is fixed on the fixed portion and coaxially connected to the second roller 541. One end of the preload spring 543 abuts against the top wall of the slide groove 11, and the other end abuts against the rocker 542. That is, the preload spring applies a force to the top wall of the slide groove and the rocker at the same time, and the rocker applies a force to the second roller through the rotating shaft, so that the second roller presses against the top wall of the slide groove and can slide along the top wall of the slide groove. That is, the preload spring 543 and the seesaw 542 make the second roller 541 always subjected to force in the height direction, thereby controlling the free space of the sliding part 52 in the height direction and limiting the height direction of the sliding part 52. In a specific embodiment, the first roller 522 and the second roller 541 are arranged in a one-to-one correspondence.
[0031] In a specific embodiment, the vehicle-mounted movable storage system also includes a signal and power input mechanism, which includes a signal and power harness, one end of which is connected to the driving mechanism, and the other end is connected to the external input connector. In a specific embodiment, a chain 60 is provided on the outer shell of the signal and power harness, one end of which is connected to the base 10, and the other end is connected to the sliding part 52, so as to input the control signal on the whole vehicle into the sliding center console, so as to facilitate the passengers to control the center console. Therefore, when the sliding mechanism 50 slides back and forth, the chain 60 and the signal and power harness can be driven to move with the sliding mechanism. The chain 60 ensures the minimum turning radius of the signal and power harness during the movement, and reduces the risk of failure of the signal and power harness due to fatigue breakage.
[0032] According to the above embodiment, when a passenger needs to move the storage box, the switch is turned on, and the motor 31 that receives the signal will drive the rotating shaft to rotate, and the rotating shaft will drive the worm gear mechanism 32 to rotate. Since the worm gear mechanism 32 is fixed on the fixing portion 521 of the sliding mechanism 50, and the screw 40 is fixed on the base 10 through the screw fixing block. When the worm gear mechanism 32 rotates, it will move on the screw 40, driving the sliding portion having the first roller 522 and the second roller 541 to move. The sliding portion 52 limits the free space in the height direction under the action of the first roller 522 and the second roller 541, that is, the first roller 522 abuts against the bottom wall of the slide slot 11, and the second roller 541 abuts against the top wall of the slide slot 11, and the second roller 541 is always subjected to force in the height direction through the action of the preload spring 543 and the rocker 542, thereby realizing the limit of the sliding portion 52 in the height direction. The first limiting portion 53 provided at the connection between the sliding portion 52 and the sliding seat 51 interacts with the slide groove 11 on the base 10 to limit the sliding portion 52 in a straight line in the slide groove 11. The worm gear mechanism 32 has a self-locking function and can stop and start at any position of the screw rod 40, so that the sliding portion 52 can be stopped or started at any position without adding an additional locking mechanism, thereby greatly simplifying the structure of the vehicle-mounted movable storage system and saving costs.
