Description

Technical Field

[0001] The invention belongs to the technical field of automobile luggage boxes, and in particular relates to a lifting mechanism for an automobile luggage box cover. Background Art

[0002] The car trunk is also called the roof box. In order to expand the storage space, the roof box is often installed on the roof of the car to carry more self-driving equipment, luggage, etc. Compared with the roof basket, the roof box has many conveniences. For some cars with smaller trunk storage space, the roof box plays a key role. The roof box can be said to be a roof-mounted equipment that integrates a roof basket, a roof luggage net, straps, and a rainproof bag (rainproof cloth and tarpaulin).

[0003] The existing car trunk cover is usually a flip-top structure, and the trunk lock must be unlocked before the trunk cover can be opened for use, which is inconvenient to operate. In addition, the installation structure of the car trunk is complicated, which makes it inconvenient for users to disassemble and install the car trunk.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention

[0005] In order to solve the above problems, an object of the present invention is to provide a lifting mechanism for a car trunk lid.

[0006] The top end of the mounting plate is provided with a mounting groove, the bottom end of the box body is located in the mounting groove and a clamping plate is fixedly provided inside the mounting plate, and a clamping plate is fixedly provided on the outer wall of the clamping plate, a fixing plate is fixedly provided on the outer wall of the top cover, a second fixing groove is provided inside the fixing plate, and a second fixing groove is provided inside the outer wall of the box body, and a second fixing groove is provided inside the second fixing groove, and a limiting structure is provided on one end of the second fixing groove.

[0007] In one example, the threaded rod and the movable rod are configured to be threadedly connected, two groups of rotating rods are symmetrically arranged on the inner wall of the inner groove, and the first sliding groove and the first sliding column are configured to be slidingly connected, so that the threaded rod rotates to drive the movable plate to move longitudinally, and the movable plate is limited by sliding the first sliding column in the first sliding groove of the rotating rod.

[0008] In one example, the inner wall of the installation groove fits with the outer wall of the card board, and the outer wall of the card block fits with the inner wall of the card slot, so that the box can be positioned and installed in the installation groove by clamping the card board, and the card board can be fixed by clamping the card block into the card slot on the outer wall of the card board.

[0009] In one example, two sets of fixed plates are symmetrically arranged on the outer wall of one side of the top cover, and the second slide groove and the second slide column are arranged to be slidably connected, so that the top cover can be limited by sliding the second slide column in the second slide groove inside the fixed plate during the lifting process.

[0010] In one example, the limiting structure includes a return spring, a movable column, a connecting rod, a clamping column and a positioning groove, the inner wall of the second sliding column is fixedly connected with a return spring, one end of the return spring is fixedly connected with a movable column, one end of the movable column is fixedly connected with a connecting rod, the outer wall of the connecting rod is fixedly provided with a clamping column, and the outer wall of the fixed plate is provided with a positioning groove, so as to facilitate the lifting and positioning of the top cover by the limiting structure, thereby facilitating the storage and retrieval of items in the suitcase.

[0011] In one example, the second sliding column and the movable column are set to be slidingly connected, the outer wall of the clamping column fits with the inner wall of the positioning groove, and the outer wall of the fixed plate is equidistantly provided with positioning grooves, so that the clamping column can be inserted into the positioning grooves at different positions to limit the fixed plate.

[0012] The automobile trunk lid lifting mechanism proposed by the present invention can bring the following beneficial effects:

[0013] 1. When the trunk of the car needs to be replaced, the threaded rod is rotated to make the moving rod move longitudinally, and the moving rod slides in the first sliding groove through the first sliding column to make the rotating rod rotate, and the rotating rod drives the card block to be inserted into or removed from the card groove of the outer wall of the card plate, so as to facilitate the disassembly and installation of the trunk of the car;

[0014] 2. When storing or retrieving items, the connecting rod is pulled to move the card column out of the positioning groove on the outer wall of the fixed plate. At this time, the top cover slides in the second sliding groove of the fixed plate through the second sliding column to be raised or lowered. Under the action of the return spring, the connecting rod can drive the card column to be stuck in the positioning grooves at different positions to limit the fixed plate, thereby facilitating the use of the car trunk.
