Foldable mobile phones usually include a second screen body hinged to a first screen body, and the first screen body and the second screen body rotate around a hinge axis.

[0003] At present, in the design of the components for protecting the outer shell of the foldable display terminal, usually due to the inability to match the folding angle and folding thickness of the foldable display terminal, two split protection components are respectively mounted on the first screen body and the second screen body of the foldable display terminal to protect the first screen body and the second screen body of the foldable display terminal from scratches and bumps. However, there is no connection between the two split protection components, and the hinge shaft of the foldable display terminal cannot be protected, so that the hinge shaft is exposed to the outside, which is easy to be bumped and scratched, thereby affecting the foldable display terminal. In order to improve the overall aesthetics, two split protection components are also connected by a flexible connecting material (such as a rubber sheet), but when the foldable display terminal is folded, the flexible connecting material is wrapped around the hinge axis of the foldable display terminal to form protection, and when the foldable display terminal is unfolded, the flexible connecting material is deformed and accumulated, that is, the flexible connecting material moves from both sides to the middle, and the middle part of the flexible connecting material is stacked, so that the flatness of the back of the two protection components is poor, which affects the hand feel of the user, resulting in poor comfort for the user, and also affects the overall aesthetics.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0019] See also Figures 1 to 7 , the present invention provides a technical solution: a foldable assembly, including an upper cover mechanism 100, a lower cover mechanism 200 and a splicing mechanism 300; The upper cover mechanism 100 and the lower cover mechanism 200 have opposing surfaces provided with mounting grooves for mounting on the protected component; The splicing mechanism 300 includes a flexible splicing member 310 and an adjusting member 320 reciprocatingly slidably connected to the surface of the lower cover mechanism 200 away from the mounting groove along a first direction, one end of the flexible splicing member 310 is connected to the adjusting member 320, and the other end of the flexible splicing member 310 is fixedly connected to the upper cover mechanism 100; The adjusting member 320 is provided with a first position and a second position. When the adjusting member 320 is located at the first position, the upper cover mechanism 100 and the lower cover mechanism 200 are arranged in sequence along the first direction. When the adjusting member 320 is located at the second position, the projections of the upper cover mechanism 100 and the lower cover mechanism 200 along the second direction overlap. It also includes a pushing mechanism 400, which is used to push the adjusting member 320 to move from the second position to the first position; The upper cover mechanism 100 has a mounting groove on its surface for mounting the part to be protected (e.g., a foldable mobile phone, which is also a display terminal), and the lower cover mechanism 200 also has a mounting groove on its surface for mounting the part to be protected. When the part to be protected (e.g., a foldable mobile phone) is folded, the surfaces of the upper cover mechanism 100 and the lower cover mechanism 200 with the mounting grooves are in a relative state, that is, the projections along the second direction overlap. The upper cover mechanism 100 and the lower cover mechanism 200 fix the part to be protected (e.g., a foldable mobile phone) through the mounting grooves, providing all-round protection to prevent the part to be protected (e.g., a foldable mobile phone) from being subjected to external impact and wear. The mounting grooves are used to ensure that the part to be protected can be stably fixed in the mounting grooves to prevent the part to be protected from moving or falling off during use. The flexible splicing member 310 allows a flexible connection between the upper cover mechanism 100 and the lower cover mechanism 200, and provides a folding function. The flexible material has good durability and tensile resistance, ensuring that it will not be easily damaged during long-term use, and avoiding fatigue and breakage caused by frequent folding and unfolding. The position of the adjusting member 320 can be adjusted by sliding the adjusting member 320 back and forth on the lower cover mechanism 200 along the first direction, and the position of one end of the flexible connecting member can be adjusted by connecting the adjusting member 320 with one end of the flexible connecting member; For example, during use, when the adjusting member 320 is located at the second position, the projections of the upper cover mechanism 100 and the lower cover mechanism 200 along the second direction overlap, and the protective member (such as a foldable mobile phone) is in a folded state, which is convenient for carrying and storage. When the adjusting member 320 is located at the first position, one end of the flexible splicing member 310 is also located at the first position with the adjusting member 320, that is, when the upper cover mechanism 100 and the lower cover mechanism 200 are unfolded to use the protective member, the flexible splicing member 310 is pulled by the adjusting member 320 and gradually stretched out and flattened to avoid stacking, so that the upper cover mechanism 100 and the lower cover mechanism 200 are relatively flat, which improves the comfort during use. The pushing mechanism 400 can automatically push the adjusting member 320 back to the first position from the second position, simplifying the operation, improving the convenience of use, and avoiding the adjusting member 320 being stuck and immobile due to the lack of thrust when the upper cover mechanism 100 and the lower cover mechanism 200 are unfolded, requiring manual operation.

[0020] In this embodiment, as a preferred solution, the adjusting member 320 includes an adjusting rod 321 and a connecting rod 322. The side of the lower cover mechanism 200 is slidably connected to the adjusting rod 321 along a first direction through an opened groove. One end of the connecting rod 322 is fixedly connected to the end of the adjusting rod 321, and the other end is fixedly connected to an end of the flexible splicing member 310 away from the upper cover mechanism 100. The lower cover mechanism 200 is provided with a receiving groove 210 that cooperates with the flexible splicing member 310. The inner side wall of the receiving groove 210 is slidably connected to the connecting rod 322 through an opened through hole. The side of the lower cover mechanism 200 is slidably connected to the adjustment rod 321 along the first direction through the groove opened, that is, the adjustment rod 321 can slide back and forth in the lower cover mechanism 200 along the first direction, and one end of the connecting rod 322 is fixedly connected to the end of the adjustment rod 321, and the other end is fixedly connected to the end of the flexible splicing member 310 away from the upper cover mechanism 100, so as to form a connection. When the adjustment rod 321 moves, the connecting rod 322 can drive one end of the flexible connector to move along, and through the connection between the accommodating groove 210 and the connecting rod 322, it assists in limiting the connection rod 322 and limits the range of movement of the connection rod 322, providing a sliding path for the adjustment rod 321, ensuring that the adjustment rod 321 moves smoothly along the first direction, limiting the moving direction of the adjustment rod 321, and preventing the adjustment rod 321 from deviating.

[0021] In this embodiment, as a preferred solution, the flexible splicing member 310 includes a locking portion 313, a plurality of splicing blocks 311 and an elastic connecting piece 312. The plurality of splicing blocks 311 are spliced ​​with each other through the elastic connecting piece 312, one of the splicing blocks 311 is fixedly connected to the connecting rod 322, and the locking portion 313 is fixedly connected to the surface of the upper cover mechanism 100 away from the mounting groove, and is connected to the splicing block 311 through the elastic connecting piece 312; The locking portion 313 is fixedly connected to the surface of the upper cover mechanism 100 away from the mounting groove, providing a stable anchor point. The locking portion 313 ensures that the entire splicing piece will not move accidentally during use, and provides a stable reference for the movement of the splicing block 311 and the elastic connecting piece 312. The splicing block 311 is the main component of the flexible splicing piece 310, providing the basic shape and strength of the structure. Multiple splicing blocks 311 are spliced ​​with each other through the elastic connecting piece 312. A splicing block 311 is fixedly connected to the connecting rod 322. The multi-section design of the splicing block 311 allows a certain degree of flexibility while maintaining the necessary structural strength. The modular setting of the connecting block 311 allows the structure to be adjusted and expanded as needed. The elastic connecting piece 312 is used to connect multiple splicing blocks 311 to provide necessary flexibility. Highly elastic materials such as silicone, TPU or special engineering plastics are used to ensure durability after multiple bending. Through the elastic connecting piece 312, the splicing blocks 311 can be flipped and bent to a certain extent. The splicing blocks 311 are connected to the connecting rod 322. The movement of the connecting rod 322 can drive the splicing blocks 311 to move along, thereby avoiding the splicing blocks 311 from stacking on each other when the upper cover mechanism 100 and the lower cover mechanism 200 are unfolded.

[0022] In this embodiment, as a preferred solution, the locking portion 313 includes a locking block 3131 and a locking rod 3132. The locking block 3131 is fixedly connected to the surface of the upper cover mechanism 100 away from the mounting groove. The end surface of the locking block 3131 is connected to the locking rod 3132 through the groove. The locking rod 3132 is connected to the splicing block 311 through the elastic connecting piece 312. The elastic connecting piece 312 is used to connect the locking rod 3132 and the splicing block 311 to provide the necessary flexibility and buffering effect. The locking rod 3132 is made of high-strength metal or engineering It is made of plastic to ensure its reliability in connection and force transmission. A groove is provided on the end face of the locking block 3131, which is connected to the locking rod 3132. The locking rod 3132 can be installed or disassembled for easy replacement. That is, the end face of the locking block 3131 is sleeved on the end of the locking rod 3132 through the groove, and then the locking bolt is inserted into the end face of the locking rod. At the same time, the end face of the locking bolt abuts against the other end face of the locking block 3131, so that the locking rod is fixed in the locking block, and the locking rod can rotate in the locking block.

[0023] In this embodiment, as a preferred solution, a reinforcing strip is provided inside the splicing block 311. The material of the reinforcing strip is acrylic, and the splicing block 311 is latex. Latex has high flexibility and elasticity, can be deformed within a certain range without breaking, has good shock absorption and buffering properties, can effectively absorb external shocks and vibrations, and can effectively protect the hinge axis of the protective part. Acrylic has high rigidity and hardness, which can provide strong support inside the splicing block 311, and the acrylic material is relatively lightweight, which can improve the structural strength without significantly increasing the weight. The reinforcing strip can support the splicing block 311 at multiple points and is evenly distributed inside the splicing block 311 to improve the overall strength.

[0024] In this embodiment, as a preferred solution, a tempered cover plate 110 is embedded in the bottom of the groove of the upper cover mechanism 100, and the locking portion 313 is located on one side of the tempered cover plate 110. The tempered cover plate 110 embedded in the upper cover mechanism 100 is made of a transparent material and is used to protect the back display part of the first screen body installed in the upper cover mechanism 100. This is an existing well-known technology and is only used for reference. The material of the tempered cover plate 110 can be tempered glass or acrylic plate, which has high strength and impact resistance, while providing good transparency and touch.

[0025] In this embodiment, as a preferred solution, the upper cover mechanism 100 includes an upper cover shell 120, the tempered cover plate 110 is fixedly connected to the upper cover shell 120, the locking portion 313 is fixedly connected to the upper cover shell 120 and is located on one side of the tempered cover plate 110, and a handset hole is opened on the surface of the upper cover shell 120 at the end of the tempered cover plate 110. The upper cover shell 120 is made of high-strength plastic, metal or composite material, which is an existing public technology and is only referenced here to provide sufficient strength and durability to protect the structure installed in the upper cover shell 120. The size and shape of the handset hole are designed according to the size of the handset assembly to ensure the sound quality and protection performance.

[0027] In this embodiment, as a preferred solution, the pushing mechanism 400 includes a first magnet 410 and a second magnet 420, the first magnet 410 is fixedly connected to an end of the adjusting rod 321 away from the connecting rod 322, and the second magnet 420 is arranged on the surface of the locking portion 313 facing the adjusting rod 321 corresponding to the first magnet 410; The first magnet 410 is arranged at one end of the adjusting rod 321 to generate magnetic force. The second magnet 420 is arranged on the surface of the locking portion 313 facing the adjusting rod 321 corresponding to the first magnet 410, and interacts with the first magnet 410 to control the position and movement of the adjusting rod 321. The magnetic poles of the surfaces of the first magnet 410 and the second magnet 420 relative to each other are opposite. When the second magnet 420 approaches the first magnet 410, the magnets with the same poles repel each other, thereby generating a pushing force.
