[0002] In the related art, when the angle between the support and the supported object needs to be adjusted, the adjustment is usually realized by an adjusting mechanism between the support and the supported object. A commonly used structure of the adjusting mechanism is to set a damping sheet in a hinge, so as to generate a large friction force to support the supported object at different angles. However, such a structure is usually laborious in the process of adjusting the angle. Especially for a display screen support, when the pitch angle of the display screen relative to the support needs to be adjusted, a large force is required to rotate, and the user experience is poor.

[0024] The following refers to Figures 1 to 14 A connecting structure with adjustable elastic direction and a display screen support having the same are described.

[0025] As Figures 2 to 13As shown, the elastic direction-adjustable connecting structure according to the first aspect of the present application comprises a rotating assembly 100, a connecting assembly 200 and a torsion spring 300. The rotating assembly 100 comprises a rotating shaft 110, a first rotating member 120 and a second rotating member 130. The first rotating member 120 and the second rotating member 130 are arranged along the axial direction of the rotating shaft 110. The first rotating member 120 is provided with a first rotating groove 121, and the second rotating member 130 is provided with a second rotating groove 131. The connecting assembly 200 comprises a first limiting member 210 and a second limiting member 220 which are fixedly connected to each other. The first limiting member 210 and the second limiting member 220 are sleeved on the rotating shaft 110. The first limiting member 210 is provided with a first limiting groove 211, and the second limiting member 220 is provided with a second limiting groove 221. The torsion spring 300 is sleeved on the rotating shaft 110. The two ends of the torsion spring 300 are a first end 310 and a second end 320. The first end 310 is rotatably inserted between a third end 1211 and a fourth end 1212 of the first rotating groove 121 and between a fifth end 2111 and a sixth end 2112 of the first limiting groove 211. The second end 320 is rotatably inserted between a seventh end 2211 and an eighth end 2212 of the second limiting groove 221 and between a ninth end 1311 and a tenth end 1312 of the second rotating groove 131. The rotating assembly 100 can reciprocate relative to the connecting assembly 200 between a first position and a third position and pass through a second position. When the rotating assembly 100 is at the second position, the two ends of the torsion spring 300 are clamped between the fifth end 2111 and the seventh end 2211, and the first end 310 is located at the third end 1211, and the second end 320 is located at the ninth end 1311. When the rotating assembly 100 is at the first position, the two ends of the torsion spring 300 are clamped between the fifth end 2111 and the ninth end 1311, and the second end 320 is separated from the seventh end 2211. The first rotating groove 121 avoids the first end 310, and the second end 320 has an elastic force to drive the second rotating member 130 to rotate to the second position. When the rotating assembly 100 is at the third position, the two ends of the torsion spring 300 are clamped between the third end 1211 and the seventh end 2211, and the first end 310 is separated from the fifth end 2111. The second rotating groove 131 avoids the second end 320, and the first end 310 has an elastic force to drive the first rotating member 120 to rotate to the second position.

[0026] It can be understood that the elastic direction-adjustable connecting structure comprises a rotating assembly 100, a connecting assembly 200 and a torsion spring 300, the rotating assembly 100 comprises a rotating shaft 110, a first rotating piece 120 and a second rotating piece 130 which are fixedly arranged on the rotating shaft 110 in an axial direction, the connecting assembly 200 comprises a first limiting piece 210 and a second limiting piece 220 which are fixed to each other, the torsion spring 300 is sleeved on the rotating shaft 110, a first end 310 of the torsion spring 300 is inserted into a first rotating groove 121 of the first rotating piece 120 and can rotate between a third end 1211 and a fourth end 1212 of the first rotating groove 121, at the same time, the first end 310 is also inserted into a first limiting groove 211 of the first limiting piece 210 and can rotate between a fifth end 2111 and a sixth end 2112 of the first limiting groove 211, a second end 320 of the torsion spring 300 is inserted into a second limiting groove 221 of the second limiting piece 220 and can rotate between a seventh end 2211 and an eighth end 2212 of the second limiting groove 221, at the same time, the second end 320 is also inserted into a second rotating groove 131 of the second rotating piece 130 and can rotate between a ninth end 1311 and a tenth end 1312 of the second rotating groove 131.

[0027] Specifically, the torsion spring 300 comprises a helical section and the first end 310 and the second end 320 located at both ends of the helical section, the helical section is a metal wire wound in a helical shape, the first end 310 is an end extending along a central axis of the helical section, and the second end 320 is an end extending along the central axis of the helical section and away from the first end 310.

[0028] It can be understood that, when installed, a pre-tightening force is given to both ends of the torsion spring 300 so as to be installed in the connecting assembly 200, so that both ends of the torsion spring 300 are clamped to the fifth end 2111 of the first limiting member 210 and the seventh end 2211 of the second limiting member 220, at this time, the first end 310 is also located at the third end 1211 of the first rotating groove 121, and the second end 320 is also located at the ninth end 1311 of the second rotating groove 131, which is the state when the rotating assembly 100 is in the second position. Then, the rotating assembly 100 is rotated in the first direction, so that the ninth end 1311 of the second rotating groove 131 on the second rotating member 130 can drive the second end 320 of the torsion spring 300 to rotate, and at the same time, the second limiting groove 221 of the second limiting member 220 can avoid the second end 320, at this time, since the first end 310 of the torsion spring 300 abuts against the fifth end 2111 of the first limiting member 210, the first end 310 remains stationary, and at the same time, the first end 310 can be avoided by the first rotating groove 121 during the rotation of the first rotating member 120, until it is rotated to the first position, at this time, the first end 310 of the torsion spring 300 is located at the fifth end 2111 while being separated from the third end 1211, and the second end 320 of the torsion spring 300 is located at the ninth end 1311 while being separated from the seventh end 2211, during the rotation between the second position and the first position, the torsion spring 300 is further tightened, so that the second end 320 can exert a force on the second rotating member 130 in the opposite direction of the first direction, realizing the support of the rotating assembly 100; the rotating assembly 100 is reversed to return to the second position, and a force opposite to the first direction is exerted on the rotating assembly 100 in the second position, so that the rotating assembly 100 rotates to the third position, at this time, the third end 1211 of the first rotating member 120 can drive the first end 310 of the torsion spring 300 to rotate, the first limiting groove 211 of the first limiting member 210 avoids the first end 310, and at the same time, the second end 320 of the torsion spring 300 abuts against the seventh end 2211 of the second limiting member 220 and cannot rotate, the second rotating groove 131 of the second rotating member 130 avoids the second end 320, during the rotation between the second position and the third position, the first end 310 is separated from the fifth end 2111, the second rotating groove 131 avoids the second end 320, and the torsion spring 300 is further tightened relative to the second position, so that the first end 310 can exert a force on the first rotating member 120 in the first direction, realizing the support balance of the rotating assembly 100; therefore, the connecting structure with adjustable elastic force direction of the application can change the elastic force direction of the torsion spring 300, so as to more easily realize the adjustment of the angle and more easily adjust the pitch angle of the supported object.

[0029] It can be understood that the angle limiting structure is also included, and the angle limiting structure includes the rotating part 111 and the limiting part 500. The rotating part 111 is arranged on the circumferential side of the rotating shaft 110. The limiting part 500 is connected to the connecting assembly 200 and arranged outside the circumferential side of the rotating shaft 110, and is used for limiting the rotating part 111 between the first position and the third position. For example, as shown in FIGS. Figure 2 , Figures 11 to 12 In this embodiment, the angle limiting structure for limiting the rotating angle of the rotating assembly 100 between the first position and the third position is also included. The angle limiting structure includes the rotating part 111 arranged on the circumferential side of the rotating shaft 110 and the limiting part 500 arranged outside the circumferential side of the rotating shaft 110. The rotating part 111 can be limited in the limiting part 500 during the rotation of the rotating shaft 110, thereby limiting the rotation range of the rotating assembly 100.

[0030] It should be understood that, in addition to the structure of the rotating part 111 arranged on the circumferential side of the rotating shaft 110 and the limiting part 500 arranged outside the circumferential side of the rotating shaft 110 for limiting the rotating angle range, in some other embodiments, the length of the first rotating groove 121, the second rotating groove 131, the first limiting groove 211 and the second limiting groove 221 can also be used to limit the rotating angle of the end of the torsion spring 300. For example, when rotating from the second position to the first position, the second rotating plate just drives the second end 320 to rotate to the eighth end 2212 abutting against the second limiting plate 520, so that the second end 320 cannot continue to rotate, thereby limiting the rotation of the rotating assembly 100; when rotating from the second position to the third position, the second end 320 at the seventh end 2211 is abutted by the tenth end 1312 of the second rotating plate, so that the second rotating plate cannot continue to rotate, thereby making the maximum angle of reverse rotation of the rotating assembly 100 only reach the third position, and limiting the rotation of the rotating assembly 100 between the first position and the third position.

[0031] It can be understood that the rotating part 111 is a protrusion arranged on the circumferential side of the rotating shaft 110, and the limiting part 500 includes the first limiting plate 510 sleeved on the rotating shaft 110. The first limiting plate 510 is provided with the first rotating groove 511, and the protrusion can rotate in the first rotating groove 511 and be limited in the first rotating groove 511. For example, as shown in FIGS. Figures 12 to 13 In this embodiment, specifically, the rotating part 111 is a protrusion arranged on the circumferential side of the rotating shaft 110. The protrusion can rotate in the first rotating groove 511 of the first limiting plate 510 arranged outside the circumferential side of the rotating shaft 110 during the rotation of the shaft, and is also limited in the first rotating groove 511, thereby realizing the rotation of the rotating assembly 100 between the first position and the third position.

[0032] It should be understood that the rotating part 111 can also be provided in the form of a rotating groove opened in the circumferential direction of the rotating shaft 110, and the limiting part 500 can be provided in the form of a protrusion connected to the connecting assembly 200 and accommodated in the rotating groove. In this way, the rotating groove rotates in the process, and the protrusion is relatively stationary until one end of the two ends of the rotating groove abuts against the protrusion, thereby limiting the rotating angle of the rotating shaft 110.

[0033] It can be understood that the angle limiting structure further comprises a stop part 600 fixedly connected to the connecting assembly 200 and used for limiting the rotation of the limiting part 500. The limiting part 500 further comprises a second limiting plate 520 and a third limiting plate 530 fixed to both sides of the first limiting plate 510 in the axial direction. The second limiting plate 520 is provided with a second rotating groove 521, and the third limiting plate 530 is provided with a third rotating groove 531. The limiting part 500 can move in the axial direction so that the protrusion can be switched between the first rotating groove 511, the second rotating groove 521 and the third rotating groove 531. The protrusion can rotate along the second rotating groove 521 to limit the rotating assembly 100 between the first position and the second position. The protrusion can rotate along the third rotating groove 531 to limit the rotating assembly 100 between the second position and the third position. The overlapping area of the projections of the second rotating groove 521 and the third rotating groove 531 on the first limiting plate 510 is located in the first rotating groove 511. For example, as shown in FIG. 6, the second rotating groove 521 and the third rotating groove 531 are arranged in the form of a V-shaped groove.

Therefore, the pushing part 512 can be regarded as an adjustment switch, so as to realize the switching of the rotating range and the stress direction of the rotating assembly 100.

[0037] It should be understood that when the rotating shaft 110 is provided with the locking part for connecting with the display screen 2000, the housing 400 needs to be exposed and can avoid the rotation of the housing 400 because the locking part is connected with the display screen 2000.

The locking part 700 is locked with the rotating shaft 110 and is pressed against the side of the second rotating part 130 away from the second limiting part 220. For example, as shown in Figure 2 In the embodiment, the first limiting part 210 is located between the first rotating part 120 and the torsion spring 300. The second limiting part 220 is located between the torsion spring 300 and the second rotating part 130. The first rotating part 120 is fixed with the rotating shaft 110. Therefore, the first rotating part 120 can be a structure on the side of the rotating shaft 110 or a component sleeved and fixed with the rotating shaft 110. The connecting assembly 200 and the torsion spring 300 are loaded into the rotating shaft 110 from the end of the rotating shaft 110 away from the first rotating part 120. Then, the second rotating part 130 is sleeved on the rotating shaft 110. Subsequently, the locking part 700 is locked on the rotating shaft 110, so as to realize the locking and fixing of the second rotating part 130.

[0040] It should be understood that the damping assembly is also included, which is fixedly sleeved on the rotating shaft 110 and located between the second rotating member 130 and the locking member 700, so as to provide rotating damping to the rotating assembly 100.

[0043] It can be understood that when the rotating assembly 100 is in the first position, the display screen 2000 is in a raised angle state relative to the support 1000, and when the rotating assembly 100 is in the third position, the display screen 2000 is in a declined angle state relative to the support 1000. For example, as shown in Figure 1 and Figure 14 , in this embodiment, the display screen support can adapt to different application scenarios, for example, when the rotating assembly 100 with the display screen 2000 is in the first position, the display screen 2000 is in a raised angle state relative to the support 1000, at this time, the support 1000 can be vertically inserted on the bottom plate, or the separate support 1000 can be separated from the display screen 2000 and arranged in a spread-eagle shape on the desktop, such as a tablet, so as to support the display screen 2000.
