[0030] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please refer to Figures 1 to 5 The hinge component includes a first pressure plate 11, a side pin 2 connected to the first pressure plate 11, and a swing arm 3, a second pressure plate 12, and a first elastic element 4 sequentially sleeved on the side pin 2 and slidable along the side pin 2; the swing arm 3 is rotatable relative to the second pressure plate 12; the second pressure plate 12 and the swing arm 3 are respectively provided with a protrusion 13 and a recess 31 that cooperates with the protrusion 13; the first pressure plate 11 and the second pressure plate 12 have the same shape and size.

[0032] As can be seen from the above description, the beneficial effects of this utility model are as follows: the hinge component has a novel structure, and the first pressing plate 11 and the second pressing plate 12 have the same shape and size, which reduces the types of parts. During the assembly process, there is no need to deliberately distinguish between the first pressing plate 11 and the second pressing plate 12, which can effectively improve the assembly efficiency of the hinge component and reduce the assembly and production costs of the hinge component.

[0033] Furthermore, there are two side pins 2, which are arranged in parallel. The side pins 2 and the swing arms 3 are arranged in a one-to-one correspondence, and the two swing arms 3 rotate synchronously through the transmission assembly 5.

[0034] As described above, the two swing arms 3 can be used to connect two different external parts respectively, and the synchronous rotation of the two swing arms 3 can facilitate the closing or unfolding of the two external parts.

[0035] Furthermore, the first pressing plate 11 and the second pressing plate 12 are both sleeved on the two side pins 2.

[0036] As can be seen from the above description, the side pin 2 can be designed as a cylinder, which is convenient for processing and forming. The first pressing plate 11 and the second pressing plate 12 can slide relative to the two side pins 2 but cannot rotate relative to the side pins 2.

[0037] Furthermore, the transmission assembly 5 includes a connecting block 51 and two transmission gears 52 disposed on the connecting block 51. The connecting block 51 is sleeved on two side pins 2, and the two transmission gears 52 mesh with each other. The swing arm 3 is provided with a gear part 32 that meshes with the transmission gears 52.

[0038] As can be seen from the above description, the transmission component 5 has a simple structure, high transmission efficiency, and is easy to assemble.

[0039] Furthermore, the two ends of the transmission gear 52 are rotatably connected to the connecting block 51 and the first pressure plate 11, respectively.

[0040] As can be seen from the above description, both ends of the transmission gear 52 can be supported, which can prevent the transmission gear 52 from bending or tilting and extend the service life of the transmission gear 52.

[0041] Furthermore, it also includes a retaining ring 6, which is detachably mounted on the side pin 2 and abuts against the end of the first elastic member 4 away from the second pressure plate 12.

[0042] As can be seen from the above description, the retaining ring 6 can prevent the first pressing plate 11, the second pressing plate 12, the swing arm 3 and the first elastic element 4 from disengaging from the pin.

[0043] Furthermore, it also includes an intermediate pin 7, the two ends of which are rotatably connected to the snap ring 6 and the second pressure plate 12, respectively. A second elastic element 8 is sleeved on the intermediate pin 7 and abuts against the second pressure plate 12.

[0044] Furthermore, there are two intermediate pins 7, which are arranged in parallel, and the intermediate pins 7 and the second elastic element 8 are arranged in a one-to-one correspondence.

[0045] As can be seen from the above description, the addition of the second elastic element 8 can enhance the damping of the rotation of the swing arm 3 relative to the second pressure plate 12.

[0046] Furthermore, it also includes a retaining piece 9, which is sleeved on the side pin 2 and is located between the retaining spring 6 and the first elastic member 4.

[0047] As can be seen from the above description, setting different numbers or different widths of the binding plates 9 can adjust the length of the first elastic member 4, thereby adjusting the elastic force applied by the first elastic member 4 to the second pressure plate 12, and further adjusting the damping of the swing arm 3 relative to the second pressure plate 12.

[0048] Please refer to Figures 1 to 5 One embodiment of this utility model is a terminal device, including a first housing and a second housing connected by a hinge component. The terminal device includes, but is not limited to, a foldable mobile phone, a foldable tablet computer, etc.

[0049] The hinge component includes a first pressure plate 11, a side pin 2 connected to the first pressure plate 11, and a swing arm 3, a second pressure plate 12, and a first elastic element 4 sequentially sleeved on the side pin 2 and slidable along the side pin 2; the swing arm 3 is rotatable relative to the second pressure plate 12; the second pressure plate 12 and the swing arm 3 are respectively provided with a protrusion 13 and a recess 31 that cooperates with the protrusion 13; the first pressure plate 11 and the second pressure plate 12 have the same shape and size.

[0050] Specifically, the swing arm 3 has a cylindrical portion for assembly with the side pin 2. Multiple protrusions 13 are present, with a recess 31 formed between adjacent protrusions 13. The protrusions 13 on the swing arm 3 are evenly distributed circumferentially around the cylindrical portion. Both the first pressing plate 11 and the second pressing plate 12 have through holes for the side pin 2 to pass through. The protrusions 13 on the first pressing plate 11 and the second pressing plate 12 are evenly distributed circumferentially around the through holes. One end of the side pin 2 has a protruding first limiting boss 21, which abuts against the end of the first pressing plate 11 away from the swing arm 3 to limit the position of the side pin 2 and the first pressing plate 11. The first elastic element 4 is a spring. In other embodiments, the first elastic element 4 can be a spring sheet or a spring pad.

[0051] There are two side pins 2, both of which are cylindrical and arranged axially parallel to each other. The side pins 2 and the swing arms 3 are arranged in a one-to-one correspondence, and the two swing arms 3 rotate synchronously through the transmission assembly 5. The first pressure plate 11 and the second pressure plate 12 are both sleeved on the two side pins 2.

[0052] The transmission assembly 5 includes a connecting block 51 and two transmission gears 52 disposed on the connecting block 51. The connecting block 51 is sleeved on two side pins 2. The two transmission gears 52 have the same shape and size and mesh with each other. The swing arm 3 is provided with a gear part 32 that meshes with the transmission gears 52.

[0053] The two ends of the transmission gear 52 are rotatably connected to the connecting block 51 and the first pressure plate 11, respectively. Specifically, the two ends of the transmission gear 52 are respectively provided with protruding connecting shafts, and the connecting block 51 and the first pressure plate 11 are respectively provided with shaft holes that cooperate with the connecting shafts.

[0054] The hinge component also includes a retaining spring 6. The side pin 2 is provided with a retaining groove that cooperates with the retaining spring 6 so that the retaining spring 6 can be detachably installed on the side pin 2. The retaining spring 6 abuts against the end of the first elastic member 4 away from the second pressure plate 12.

[0055] The hinge component also includes a central pin 7, with its two ends rotatably connected to a retaining spring 6 and a second pressure plate 12, respectively. A second elastic element 8 is sleeved on the central pin 7 and abuts against the second pressure plate 12. One end of the central pin 7 has a protruding second limiting boss 71, which abuts against the end of the second pressure plate 12 away from the second elastic element 8 to limit the position of the central pin 7 and the second pressure plate 12.

[0056] Specifically, there are two intermediate pins 7, arranged in parallel, with each intermediate pin 7 corresponding to a second elastic element 8. Both intermediate pins 7 are cylindrical, and their axial directions are parallel to the axial directions of the two side pins 2. The second pressure plate 12 has a shaft hole for the intermediate pins 7 to pass through, and the retaining spring 6 has a through groove for the intermediate pins 7 to pass through. The shaft hole on the first pressure plate 11 for connecting the transmission gear 52 is the same shape and size as the shaft hole on the second pressure plate 12 for connecting the intermediate pins 7. The second elastic element 8 is a spring. In other embodiments, the second elastic element 8 can be a spring sheet or a spring pad.

[0057] The hinge component also includes a retaining piece 9, which is sleeved on the side pin 2 and is located between the retaining spring 6 and the first elastic member 4.

[0058] The working principle of the hinge component disclosed in Embodiment 1 of this utility model is briefly described as follows: Under the action of the first elastic member 4 and the second elastic member 8, the second pressing plate 12 presses against one end of the swing arm 3, and the other end of the swing arm 3 presses against the first pressing plate 11; when the swing arm 3 rotates relative to the first pressing plate 11 around the axial direction of the side pin 2, the side of the protrusion 13 on the swing arm 3 presses against the side of the protrusion 13 on the first pressing plate 11 and the second pressing plate 12, thereby driving the swing arm 3 to have a tendency to move away from the first pressing plate 11 along the axial direction of the side pin 2, and driving the second pressing plate 12 to have a tendency to move away from the swing arm 3 along the axial direction of the side pin 2. At this time, the first elastic member 4 and the second elastic member 8 will resist the movement of the second pressing plate 12 and the swing arm 3, forming resistance to the rotation process of the swing arm 3.

[0059] In summary, the hinge component provided by this utility model has a novel structure. The first pressure plate and the second pressure plate have the same shape and size, which reduces the types of parts. During the assembly process, there is no need to deliberately distinguish between the first pressure plate and the second pressure plate, which can effectively improve the assembly efficiency of the hinge component and reduce the assembly and production costs of the hinge component.

[0060] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
