DETAILED DESCRIPTION

[0022] Based on this, in order to improve the problem that the box body in the related art ignores to supplement buffer materials inside the box body and cannot protect the contents in the box from the inside in a deeper level, the embodiments of the present application provide the following solutions.

[0023] Please refer to Figs. 1-3, including an outer box body 1, an inner box body 2 and a protection mechanism 3, the protection mechanism 3 comprising a buffer assembly 31, a compression-resistant assembly 32 and a buffer sponge 33, the outer box body 1 being sleeved on the inner box body 2, a placing cavity 4 being formed between the outer box body 1 and the inner box body 2, the buffer assembly 31 being arranged in the placing cavity 4, the compression-resistant assembly 32 being arranged on the outer box body 1, and the buffer sponge 33 being bonded inside the inner box body 2, the buffer assembly 31 comprising a buffer spring 311, a buffer foam 312 and a buffer plate 313, the buffer plate 313 adopting one of a honeycomb structure, a mesh structure and a multi-layer structure, the buffer plate 313 being provided with a through hole, the buffer spring 311 and the buffer foam 312 being arranged in the through hole, and one end of the buffer spring 311 and the buffer foam 312 abutting against the inner wall of the outer box body 1 and the other end abutting against the outer wall of the inner box body 2.

[0024] Thus, the outer box body 1 and the inner box body 2 form a multi-layer structure and form the placing cavity 4 for placing the buffer assembly 31, the buffer spring 311, the buffer foam 312 and the buffer plate 313 in the buffer assembly 31 form a multi-layer buffering mechanism, the buffer spring 311 first provides elastic support, absorbs impact energy and reduces vibration transmission, then the buffer foam 312 further absorbs impact energy and provides additional buffering effect, finally, the buffer plate 313 adopts a honeycomb structure, a mesh structure or a multi-layer structure, which can disperse impact force and enhance overall buffering performance; the buffer plate 313 is provided with a through hole, so that the buffer spring 311 and the buffer foam 312 can be uniformly distributed to provide all-round buffering protection; the compression-resistant assembly 32 enhances the compression resistance of the outer box body 1 to prevent the box from deforming or being damaged when subjected to external pressure; the outer box body 1 and the inner box body 2 are made of high-strength materials to ensure the durability and reliability of the box, and the buffer spring 311 and the buffer foam 312 are made of high-elasticity materials to ensure their stable performance during long-term use.

[0025] Alternatively, in some embodiments, referring to Fig. 1 and Fig. 2 , the compression-resistant assembly 32 comprises a reinforcing block 321, a transverse anti-collision strip 322 and a longitudinal anti-collision strip 323, the reinforcing block 321 being arranged in the placing cavity 4, the inner face of the reinforcing block 321 abutting against the outer wall of the inner box body 2 at four corners, the outer face of the reinforcing block 321 abutting against the inner wall of the outer box body 1 at four corners, the transverse anti-collision strip 322 and the longitudinal anti-collision strip 323 being bonded on the outer box body 1, the transverse anti-collision strip 322 and the longitudinal anti-collision strip 323 being integrally connected, the transverse anti-collision strips 322 on the four sides of the outer box body 1 being connected by a mesh connecting belt 10, and the mesh connecting belt 10 being elastic.

[0026] In this way, the reinforcing block 321 is arranged at the four corners in the placing cavity 4 and tightly abuts against the four corners of the inner box body 2 and the outer box body 1, effectively enhancing the compression resistance of the four corners of the box body. The four corners are the parts of the box body that are most easily impacted and compressed, and the design of the reinforcing block 321 can prevent the box body from being deformed or damaged when it is subjected to extrusion or impact. The transverse anti-collision strips 322 and the longitudinal anti-collision strips 323 are bonded to the outer box body 1 to form a grid-shaped support structure, which becomes an integral anti-collision frame and can uniformly disperse external impact forces to the entire surface of the box body, avoiding damage caused by excessive local stress and significantly improving the compression resistance and impact resistance of the side surface of the box body. The mesh connection belt 10 is elastic and can be moderately stretched to relieve pressure and prevent the box body from being deformed due to excessive extrusion when the box body is subjected to extrusion.

[0027] Optionally, in some embodiments, referring to Figs. 1-3 , the outer box body 1 is rotationally connected with a universal wheel 5, the universal wheel 5 is made of fiber-reinforced composite material, providing high strength and good cushioning performance, and the outer box body 1 is provided with a pull rod 6 at an end away from the universal wheel 5, the pull rod 6 is movably connected with the outer box body 1.

[0028] In this way, the universal wheel 5 is installed at the bottom of the outer box body 1 to form four-point support, and the universal wheel 5 can rotate by 360 degrees, allowing the box body to be moved flexibly in narrow spaces or complex road conditions. The pull rod 6 can be pulled out, and a notch is formed at the handle of the pull rod 6 to facilitate the user to hold the notch with fingers and stretch the pull rod 6. The combination of the pull rod 6 and the universal wheel 5 allows the box body to be easily pulled, which is particularly suitable for long-distance moving occasions such as airports and stations. The universal wheel 5 is made of fiber-reinforced composite material (such as carbon fiber and glass fiber), which has high strength, high rigidity and wear resistance, can withstand large loads and frequent use, and has elasticity on one hand to absorb part of the impact energy and reduce vibration transmission to the inside of the box body to protect the contents in the box, and corrosion resistance on the other hand, suitable for humid, rainy or other harsh environments, prolonging the service life of the universal wheel 5.

[0029] Optionally, in some embodiments, referring to Fig. 1 and Fig. 3 , the outer box body 1 is fixedly connected with a shockproof lock 7, which is used to prevent the box cover from being accidentally opened when the box body is impacted.

[0030] In this way, when the box is subjected to external impact or vibration (such as bumping, collision or falling during transportation), the shockproof lock 7 can effectively prevent the accidental opening of the box cover, avoid the scattering or loss of the contents in the box, and the shockproof lock 7 has a certain elasticity or buffering mechanism, which can absorb part of the energy when impacted, reducing the direct impact of vibration on the lock. The shockproof lock 7 is used in cooperation with the main lock to form a double protection mechanism, further improving the safety of the luggage, and the shockproof lock 7 is usually designed in an easy-to-operate form, which can be opened or closed by simply pressing or sliding by the user, and is convenient to use.

[0031] Optionally, in some embodiments, referring to Fig. 3 , the inner box 2 is bonded with a sliding rail 8 inside, and the sliding rail 8 is slidingly connected with a partition plate 9.

[0032] In this way, by pulling the partition plate 9, the partition plate 9 slides on the sliding rail 8, and the inner space of the inner box 2 is divided into multiple parts, which is beneficial to the classification and placement of the articles, and prevents the articles from colliding or extruding each other during transportation, especially suitable for protecting fragile or valuable articles. If there is no need to separate the inner space of the inner box 2, the partition plate 9 is pushed to the two ends of the sliding rail 8, so that the partition plate 9 abuts against the inner wall of the inner box 2, and at this time the inner space of the inner box 2 is a complete space; The partition plate 9 has two, and at most can divide the inner space of the inner box 2 into three parts; the partition plate 9 is perpendicular to the direction of the sliding rail 8, and at the same time of separating the space, the combination of the partition plate 9 and the sliding rail 8 plays a supporting role, which is another line of defense to protect the articles in the box.

[0033] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
