Description

TECHNICAL FIELD

[0001] The utility model relates to travel case technical field, concretely relates to a front cover structure of travel case. BACKGROUND

[0002] In today's fast-paced modern life, travel has become a common activity of people's daily leisure and business travel, and the functionality and convenience of travel cases as essential storage tools for travel are highly concerned. With the increasing demand of travelers for use experience, the structural design of travel cases is also evolving.

[0003] A typical existing travel case covers a case shell, the front side of the case shell is open, and a front cover is arranged at the opening position to achieve closed protection of the items in the case. The connection between the front cover and the case shell adopts a hinge on the lower side to achieve a rotating effect, allowing the front cover to open and close relative to the case shell. At the same time, a lock hook is provided on the inner side of the upper side of the front cover, and a bag lock is provided in the case shell corresponding to the lock hook. The opening and closing state of the front cover is controlled by locking and unlocking the lock hook with the bag lock to ensure the safety of the items during travel.

[0004] However, upon further analysis of this design, it is not difficult to realize that it has many drawbacks. On the one hand, the hinge is used as a rotating connecting piece, which has a relatively complex structure and requires precise assembly process in actual production process. This not only consumes a lot of man-hours and increases the complexity of assembly, but also significantly increases the manufacturing cost of the entire travel case from the cost accounting point of view, which weakens the price competitiveness of the product in the market.

[0005] On the other hand, from the actual use scene of the user, when the bag lock is unlocked from the lock hook, the front cover should ideally automatically pop up to open, making it convenient for the user to take the items. However, the reality is often disappointing. If the front cover is not equipped with an automatic pop-up mechanism or the pop-up mechanism fails, it is difficult for the user to find a suitable force point with their hands since it is on the inner side of the case shell. It is easy to damage the surface of the case by forcibly using fingers to dig into the gap or groping for the force point to open the front cover, which greatly reduces the efficiency of opening the case to take the items, causes unnecessary trouble during the journey, and seriously affects the convenience of using the travel case.

[0006] In summary, in the current situation of travel cases pursuing efficiency, convenience and low cost, the defects of the existing travel case front cover structure need to be solved, which provides an urgent and necessary opportunity for the research and development of a new travel case front cover structure.
