Description

Technical Field

[0001] This utility model relates to a car tailgate storage box. Background Technology

[0002] Currently, most car storage boxes on the market are of the gas spring type, with the door connected to the box body via a gas spring. The box contains fixed storage compartments for storing items carried in the vehicle. While this type of storage box offers a degree of stability, it still has the following drawbacks:

[0003] Limited storage space: Due to the limitations of the gas spring structure, the internal space of the storage box is usually quite small, making it difficult to meet the storage needs of large items.

[0004] Unattractive design: Gas spring storage boxes are usually equipped with exposed handles or front opening buttons, which detracts from the overall aesthetics of the vehicle. Utility Model Content

[0005] The purpose of this utility model is to provide a car tailgate storage box with a large storage space and a limited opening mechanism for the lid.

[0006] The purpose of this utility model is achieved as follows:

[0007] A car tailgate storage box includes a box body, a box cover, and a hinge with an angle limiting function. The inner cavity of the box body is a storage space. The surface of the box body has an open opening that connects to the storage space. One end of the hinge is connected to the bottom of the box body, and the other end of the hinge is connected to the box cover. The box cover rotates around the hinge to open or close the storage space.

[0008] It also includes an elastic pull strap, one end of which is connected to the box body and the other end of which is connected to the box lid;

[0009] When the lid is rotated to open the storage space, the hinge restricts the rotation angle of the lid, while the lid pulls the elastic strap to keep the elastic strap taut.

[0010] The design, which combines an elastic pull strap with a hinge that has an angle limiting function, provides a good cushioning effect when the lid is rotated to open or close, avoiding impact on the structure caused by sudden opening or closing and effectively extending the overall service life of the storage box.

[0011] The elastic pull strap is a replaceable part. When it reaches the end of its service life, users can easily replace it with a new one, thereby improving the maintenance convenience and cost-effectiveness of the storage box.

[0012] While fulfilling the function of connecting the lid, the hinge also controls the rotation range of the lid through the angle limiting function, avoiding damage or safety hazards caused by excessive opening of the lid, and ensuring the stability and safety of use.

[0013] The storage space in this design is compact, and the reasonable opening design and rotating lid make it easy for users to store and retrieve items, thus improving the space utilization efficiency of the storage box.

[0014] Compared with the traditional pneumatic rod structure, the introduction of the elastic strap not only simplifies the structure, but also makes the opening and closing process smoother and more natural, improving the user experience.

[0015] The objective of this utility model can also be achieved by the following technical measures:

[0016] Furthermore, the hinge includes an upper connecting piece, a lower connecting piece, and a pivot pin. The lower connecting piece is provided with at least two lower bushings, and a connection area is formed between the lower bushings. A limit notch is provided at the end of the lower bushing near the connection area. The lower connecting piece is connected to the housing.

[0017] The upper connecting piece is provided with an upper bushing, and the end of the upper bushing is provided with a protrusion. The upper connecting piece is connected to the box cover.

[0018] The upper bushing is placed in the connecting area, and the protrusion enters the limiting notch. The pin passes through the upper bushing and the lower bushing in sequence. The upper connecting piece and the lower connecting piece rotate around the pin as the rotation center. The limiting notch restricts the rotation angle of the protrusion, thereby restricting the rotation angle of the upper connecting piece.

[0019] The hinge features a silent hinge design with a silent bearing inside, resulting in extremely low noise during opening and closing, enhancing the user experience. The hinge's limiting structure restricts the lid's rotation angle, preventing accidental over-opening and ensuring safety.

[0020] By setting a limiting notch at the end of the lower bushing of the hinge connecting piece and a protruding structure at the end of the upper bushing of the upper connecting piece, the rotation angle of the upper connecting piece can be effectively limited when the protrusion of the upper bushing enters the limiting notch, thereby precisely controlling the opening and closing range of the lid and ensuring that the lid moves within the preset range, avoiding damage or safety risks caused by excessive opening.

[0021] The upper and lower connecting pieces in the hinge structure are tightly connected by a pivot pin, and combined with the limiting notch and protrusion design, a stable and reliable connection method is achieved. This not only ensures the flexible opening and closing of the lid, but also improves the durability and impact resistance of the entire storage box.

[0022] This hinge design conceals the limiting and connecting functions, embedding the complex structure within the connection between the upper and lower bushings and the box body, maintaining the simplicity of the storage box's external design and enhancing the overall aesthetics of the product.

[0023] Furthermore, the rotation angle is 0-90°.

[0024] Furthermore, one end of the elastic pull strap is detachably connected to the inner wall of the box, and the other end of the elastic pull strap is detachably connected to the upper part of the box lid.

[0025] Both ends of the elastic pull strap are detachable, allowing users to easily replace the elastic pull strap when it reaches the end of its service life without disassembling the entire storage box or interfering with other components. This significantly reduces maintenance costs and difficulty, and extends the overall service life of the storage box.

[0026] Furthermore, it also includes a lock body, a controller, and a latch. The lock body is located at the upper part of the inner cavity of the box, the latch is located at the upper part of the box cover, and the controller is located on the side wall of the box and connected to the lock body.

[0027] When the lid rotates to close the storage space, the latch inserts into the latch groove of the lock body, and the controller controls the lock body to lock or unlock the latch.

[0028] By adding a lock body, latch, and controller to the storage box, the lid can be securely locked when closed by inserting the latch into the latch groove of the lock body. This effectively prevents the lid from being accidentally opened due to vibration or external force, ensuring the safety of items in the storage space.

[0029] The controller, connected to the lock body, enables remote or automatic control of the bolt, improving ease of use and providing a modern experience.

[0030] By placing the controller on the side wall of the box and embedding it in the lock body, not only is the complex lock control structure hidden, but the exposed controller is also avoided from affecting the overall aesthetics, making the storage box look simpler and smoother, which meets the aesthetic requirements of modern automotive design.

[0031] The controller is designed to integrate with the vehicle's intelligent systems, enabling remote control or linkage with in-vehicle anti-theft systems. For example, it allows for one-click locking or unlocking via the owner's mobile phone or central control screen, further enhancing the user experience and aligning with the trend of automotive intelligence.

[0032] The beneficial effects of this utility model are as follows:

[0033] In this invention, the controller is designed on the side, avoiding the front controller from being exposed, and further enhancing the overall aesthetics of the storage box.

[0034] This invention features an elastic pull strap design that provides cushioning when the lid opens and closes, preventing impact damage to the hinges and rubber strips and extending the storage box's lifespan. Furthermore, the elastic pull strap facilitates replacement and maintenance, while also enhancing the load-bearing capacity of the outer lid, meeting the needs of various usage scenarios.

[0035] This invention provides a limiting notch at the lower bushing end of the hinge connecting piece and a protruding structure at the upper bushing end of the upper connecting piece. When the protrusion of the upper bushing enters the limiting notch, the rotation angle of the upper connecting piece can be effectively limited, thereby precisely controlling the opening and closing range of the lid and ensuring that the lid moves within a preset range, avoiding damage or safety risks caused by excessive opening.
