Description

Technical Field

[0001] This utility model relates to the technical field of automobile trunks, and in particular to a connecting structure for automobile trunk cover plates. Background Technology

[0002] The trunk lid is a cover located inside the trunk of a car. Its main function is to cover the storage space at the bottom of the trunk, serving to separate, hide, and protect items. It can separate items in the trunk from spare tires, tools, and other components, making the trunk interior tidier. It can also prevent placed items from falling into the bottom space and, to some extent, provide sound insulation and dust prevention.

[0003] Existing patent CN212890122U discloses a connecting structure for a car trunk lid, including a storage box at the bottom and rear side panels on both sides of the storage box; it also includes a flexible lid body, with snap-fit ​​rails located above the storage box within the rear side panels on both sides. The snap-fit ​​rails include a first snap-fit ​​rail and a second snap-fit ​​rail arranged vertically and extending horizontally, with the first snap-fit ​​rail above the second snap-fit ​​rail. The two ends of the flexible lid body are respectively snapped into the first or second snap-fit ​​rail, dividing the trunk space into two spaces; alternatively, the bent flexible lid body has an upper body and a lower body, with the two ends of the upper body snapped into the first snap-fit ​​rail and the two ends of the lower body snapped into the second snap-fit ​​rail, dividing the trunk space into three spaces. This connecting structure can adjust the trunk space allocation according to different storage needs, has a simple appearance, and is easy to operate.

[0004] Problems identified with existing technology: Traditional cover plates often use snap-on or friction-type limiting mechanisms, which have defects such as poor limiting accuracy and weak locking force. This makes the cover plate prone to accidental displacement due to vehicle bumps or external force when it is open, and may even pose a safety hazard. Utility Model Content

[0005] In view of the above technical problems, the present invention provides a connection structure for a car trunk cover, characterized in that it includes a quick-release adjustment structure and a cover body structure, wherein the quick-release adjustment structure is disposed on both sides of the cover body structure, and the quick-release adjustment structure is connected to the cover body structure by bolts and nuts.

[0006] The quick-release adjustment structure consists of a mounting plate, a motor, a telescopic limit rod, a dual-axis rotating gear, and a crank. A motor is mounted on one side of the mounting plate, and the mounting plate is connected to the motor. The output end of the motor is connected to the dual-axis rotating gear via a key. A crank is mounted on one side of the dual-axis rotating gear, and the dual-axis rotating gear and the crank are connected via an eccentric pin. The telescopic rod is an electrically operated telescopic limit rod, used to insert into the tooth groove of the dual-axis rotating gear to achieve engagement and limitation. When the dual-axis rotating gear needs to be limited, the built-in drive motor of the electrically operated telescopic limit rod operates, driving the limit rod body to extend axially through the threaded engagement of the lead screw and slider. Its end aligns with and inserts into the tooth groove of the dual-axis rotating gear, using the mechanical engagement between the limit rod and the tooth groove to restrict the gear's rotation. When the limitation is released, the drive motor reverses, the limit rod body retracts axially, disengages from the tooth groove, and the dual-axis rotating gear resumes free rotation.

[0007] The cover plate body structure consists of a composite cover plate base layer, an edge reinforcing frame, a buffer sound insulation layer, and an anti-slip and wear-resistant layer. An edge reinforcing frame is provided on one side of the composite cover plate base layer, and the edge reinforcing frame on one side of the composite cover plate base layer is an integrally formed structure. A buffer sound insulation layer is provided at the bottom of the composite cover plate base layer, and an anti-slip and wear-resistant layer is provided on one side of the edge reinforcing frame.

[0008] The beneficial effects of this utility model are as follows: This invention improves the quick-installation adjustment structure, which consists of a mounting plate, a motor, a telescopic limit rod, a dual-axis rotating gear, and a crank. The mounting plate serves as the "basic carrier" of the quick-installation adjustment structure, enabling rapid installation on a vehicle. The motor, as the power source, drives the crank by the dual-axis rotating gear, achieving automatic opening and closing or angle adjustment of the cover without manual operation. The telescopic limit rod achieves "locking and limiting" by inserting into the tooth groove of the dual-axis rotating gear. Compared with traditional snap-on or friction-type limiting, the tooth groove locking provides higher limiting accuracy and stronger locking force, effectively preventing accidental displacement of the cover during opening and improving structural safety.

[0009] This utility model improves the cover plate body structure, which consists of a composite cover plate base, an edge reinforcing frame, a buffer sound insulation layer, and an anti-slip and wear-resistant layer. The edge reinforcing frame and the composite cover plate base are integrally molded, which can effectively enhance the deformation resistance and impact resistance of the cover plate edge and avoid the failure of the entire cover plate structure due to edge cracking. The buffer sound insulation layer can absorb sound wave energy through its own porous structure, block the noise propagation path, and reduce the penetration of trunk noise into the cabin. Especially when driving at high speed, it can significantly reduce noise interference inside the vehicle. In addition, when the cover plate is opened and closed, the buffer sound insulation layer can act as a buffer pad. The anti-slip and wear-resistant layer is set at the opening and closing of the cover plate, which can reduce the friction between the cover plate and the car during the opening and closing process.

Detailed Implementation Example 1

[0011] This utility model provides a connection structure for a car trunk cover, characterized in that the quick-release adjustment structure consists of a mounting plate 1, a motor 2, a telescopic limit rod 3, a dual-shaft rotating gear 4, and a crank 5; the cover body structure consists of a composite cover base layer 6, an edge reinforcing frame 7, a buffer sound insulation layer 8, and an anti-slip and wear-resistant layer 9. A motor 2 is installed on one side of the mounting plate 1, and the mounting plate 1 is connected to the motor 2. The output end of the motor 2 is connected to the dual-shaft rotating gear 4 by a key. A crank 5 is installed on one side of the dual-shaft rotating gear 4, and the dual-shaft rotating gear 4 and the crank 5 are connected by an eccentric shaft pin. An edge reinforcing frame 7 is installed on one side of the composite cover plate base 6, and the edge reinforcing frame 7 is an integrally formed structure. A buffer sound insulation layer 8 is installed at the bottom of the composite cover plate base 6, and an anti-slip and wear-resistant layer 9 is installed on one side of the edge reinforcing frame 7. Example 2

[0012] When using this utility model, first complete the preliminary assembly and debugging. Align the quick-release adjustment structures on both sides with the preset installation holes in the trunk of the car using the mounting plate 1, and tighten them with high-strength bolts. Then connect the edge reinforcing frame 7 of the cover plate body structure to the crank 5 with nuts to ensure that there is no gap or shaking at the connection. Then connect the power supply of the motor 2.

[0013] For everyday storage, if you need to open the cover to access items at the bottom, you can issue a command via the car's central control screen or the touch button inside the trunk. After the motor 2 starts, it drives the dual-axis rotating gear 4 to rotate clockwise. The crank 5 then drives the cover body to flip upward. When the cover reaches the appropriate opening angle, you can manually extend the telescopic limit rod 3 and insert it into the tooth groove of the dual-axis rotating gear 4 to form a rigid lock. Even if the vehicle is bumped or accidentally touched, the cover will not shift.

[0014] When closing the cover, the telescopic limit rod 3 retracts and unlocks first, and the motor 2 reverses to drive the cover to slowly fall back. When it contacts the bottom of the trunk, the buffer sound insulation layer 8 acts as a buffer to avoid noise caused by hard impact. For daily cleaning, simply wipe the composite cover base layer 6. Its wear-resistant material can resist frequent friction wear. If maintenance is required after long-term use, the motor 2, telescopic limit rod 3 and other components can be inspected and replaced by removing the bolts at the mounting plate 1. The overall operation is convenient and efficient, and fully adaptable to diverse usage scenarios.
