[0029] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Embodiment 1:

[0031] See also Figure 1-Figure 6 , a sliding cover storage box, comprising a storage box shell 1, the upper end of the storage box shell 1 is movably connected with a storage box cover plate 2;

[0032] The inner walls of both sides of the storage box housing 1 are provided with guide grooves 11 , and the storage box cover 2 has a track shaft 3 that can move along the guide grooves 11 ; wherein the track shaft 3 is symmetrically arranged on both sides of the storage box cover 2 .

[0033] A movable limiting movable part 4 is also installed in the guide groove 11. When the storage box cover 2 is in a fully closed state or a fully open state, the limiting movable part 4 contacts the track shaft 3 and applies pressure thereto, so that the track shaft 3 presses against the inner wall of the guide groove 11; when the storage box cover 2 is subjected to external force and enters a semi-open state from a fully closed state or a fully open state, the track shaft 3 applies pressure on the limiting movable part 4, so that the limiting movable part 4 is deformed or moved. After the limiting movable part 4 is deformed or moved, enough space is vacated in the guide groove 11 for the track shaft 3 to move; wherein, when the storage box cover 2 is in an open state, the limiting movable part 4 is in a natural state; when the storage box cover 2 is in a closed state, the track shaft 3 is restricted by the limiting movable part 4, which is beneficial to prevent the track shaft 3 from moving downward.

[0034] See also Figure 3-Figure 6 The guide groove 11 provides a motion trajectory for the track shaft 3, and the two ends of the guide groove 11 have a locking point 12 and a starting point 13; the track shaft 3 rolls in the guide groove 11, and the track shaft 3 moves from the starting point 13 to the locking point 12, so that the storage box shell 1 changes from an open state to a closed state; the track shaft 3 moves from the locking point 12 to the starting point 13, so that the storage box shell 1 changes from a closed state to an open state.

[0035] In the above technical solution, the limiting movable part 4 is arranged at the front end of the guide groove 11 close to the locking point 12. The limiting movable part 4 contacts the track shaft 3 and applies pressure thereto, so that the track shaft 3 presses against the inner wall of the guide groove 11. At this time, the storage box cover 2 is in a fully closed state or a fully open state.

[0036] During specific operation, the starting position is located at the tail end of the storage box shell 1 facing the inside of the armrest box, the locking position is located in the middle of the storage box, and the track shaft 3 is located at the tail end of the storage box cover 2 facing the inside of the armrest box. When the track shaft 3 is located at the locking point 12, the top of the storage box shell 1 is covered by the storage box cover 2 and is in a fully closed state or a fully open state. When the track shaft 3 leaves the locking point 12, the storage box shell 1 gradually opens until the track shaft 3 is located at the starting point 13, and the storage box shell 1 is in a fully open state, which is convenient for users to take items in the box.

[0037] The upper inner wall or the lower inner wall of the guide groove 11 has a through groove 14, and the limiting movable part 4 is movably installed in the through groove 14, and an elastic part is installed on the limiting movable part 4; the limiting movable part 4 includes a contact part that can contact the track shaft 3; under normal conditions, the contact part is acted upon by the elastic part to extend from the through groove 14 into the guide groove 11, and when the track shaft 3 moves and applies pressure to the limiting movable part 4, the contact part is pressed into the through groove 14 by the track shaft 3.

[0038] In the above technical solution, when the track shaft 3 rolls to the locking point 12 in the guide groove 11, the track shaft 3 is limited by the limiting movable part 4, so that the storage box shell 1 is in a closed state; when the track shaft 3 rolls toward the starting point 13 in the guide groove 11, the track shaft 3 is not affected by the limiting movable part 4, and at this time the storage box shell 1 is in an open state.

[0039] The outer wall of the storage box housing 1 has a mounting buckle 15 , and one end of the position-limiting movable member 4 is penetrated by a mounting hole 43 , the mounting hole 43 matches the mounting buckle 15 , and the position-limiting movable member 4 is rotatably connected to the mounting buckle 15 through the mounting hole 43 .

[0040] In the above technical solution, the mounting buckle 15 and the mounting hole 43 cooperate with each other, so that the limiting movable part 4 can rotate within a certain range with the mounting buckle 15 as the center, which limits the activity space of the limiting movable part 4 in the through groove 14 to a certain extent, effectively avoiding the displacement between the limiting movable part 4 and the through groove 14 when the limiting movable part 4 moves in the through groove 14, and effectively preventing the limiting movable part 4 from falling off from the mounting buckle 15, thereby improving the working efficiency of the limiting movable part 4.

[0041] The elastic member includes a fixed portion and a movable portion, wherein the fixed portion is connected to or fixed to the storage box housing 1 , and the movable portion is connected to the limiting movable member 4 and applies pressure thereto so that the contact portion of the limiting movable member 4 extends into the guide groove 11 .

[0043] The limiting movable part 4 is provided with a spring hole 44, one end of the return spring 42 extends into the spring hole 44, and the other end of the return spring 42 is connected to the spring limiting plate 41; wherein, the setting of the spring hole 44 can effectively strengthen the connection between the return spring 42 and the limiting movable part 4.

[0044] During specific operation, under the action of the return spring 42 and the spring limit plate 41, the contact portion of the limit movable part 4 protrudes from the inner wall of the guide groove 11 through the through groove 14, and the storage box cover 2 is in the open state. At this time, the track shaft 3 is located in the guide groove 11 at a position away from the locking point 12, and the limit movable part 4 is not affected by the track shaft 3 and is in a natural state; during the closing process of the box body, the track shaft 3 rolls toward the locking point 12, and the track shaft 3 moves along the movement trajectory of the guide groove 11. During this process, the track shaft 3 contacts the contact portion of the limit movable part 4, and the track shaft 3 moves and contacts the contact portion of the limit movable part 4. When pressure is applied to the contact part, the contact part is pressed into the through groove 14 by the elastic member, and thus will not affect the integrity of the movement trajectory in the guide groove 11, so that the track shaft 3 can reach the predetermined position of the locking point 12 through the movement trajectory in the guide groove 11; after the storage box cover 2 reaches a closed state along the movement trajectory in the guide groove 11, the limiting movable part 4 is pushed out by the return spring 42, so that the contact part of the limiting movable part 4 extends from the through groove 14 into the guide groove 11, and then the contact part presses against the track shaft 3, applying pressure thereto, so that the track shaft 3 presses against the inner wall of the guide groove 11, preventing the track shaft 3 from moving downward, thereby limiting the track shaft 3.

When the track shaft 3 leaves the locking point 12, the storage box shell 1 gradually opens until the track shaft 3 is located at the starting point 13, and the storage box shell 1 is in a fully open state, which is convenient for users to take items in the box.

[0052] The upper inner wall or the lower inner wall of the guide groove 11 has a through groove 14, and the limiting movable part 4 is movably installed in the through groove 14, and an elastic part is installed on the limiting movable part 4; the limiting movable part 4 includes a contact part that can contact the track shaft 3; under normal conditions, the contact part extends from the through groove 14 into the guide groove 11, and when the track shaft 3 moves and applies pressure to the limiting movable part 4, the contact part is pressed into the through groove 14 by the elastic part.

[0055] In the above technical solution, the mounting buckle 15 and the mounting hole 43 cooperate with each other, so that the limiting movable part 4 can rotate within a certain range with the mounting buckle 15 as the center, which limits the activity space of the limiting movable part 4 in the through groove 14 to a certain extent, effectively avoiding the displacement between the limiting movable part 4 and the through groove 14 when the limiting movable part 4 moves in the through groove 14, and effectively preventing the limiting movable part 4 from falling off from the mounting buckle 15, thereby improving the working efficiency of the limiting movable part 4.
