[0060] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0061] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0062] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0063] In this application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. "And / or" is just a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the previous and next associated objects are in an "or" relationship.

[0079] Reference Figure 4 As shown, two adjacent first parts 2a of the first hinge structure 2 are rotatably connected via the first pivot structure 24, that is, the mounting seat 21 and the connecting portion 22 are rotatably connected via the first pivot structure 24, specifically, the two second fixing plates 212 and the two second connecting plates 222 are rotatably connected one-to-one via the two first pivot structures 24; the connecting portion 22 and the first display screen mounting portion 23 are also rotatably connected via the first pivot structure 24, specifically, the two second connecting plates 222 and the two second mounting plates 232 are also rotatably connected one-to-one via the two first pivot structures 24.

[0080] The first rotating shaft structure 24 may include a first rotating shaft 241, a first elastic member 242 and two first limiting portions 243; when the first rotating shaft structure 24 connects the second fixing plate 212 and the second connecting plate 222, the first rotating shaft 241 passes through the mounting through hole and the first connecting through hole; when the first rotating shaft structure 24 connects the second connecting plate 222 and the second mounting plate 232, the first rotating shaft 241 passes through the second connecting through hole and the third connecting through hole.

[0081] The two first limiting portions 243 are disposed at opposite ends of the first rotating shaft 241. The area of ​​the cross section of the first limiting portion 243 perpendicular to the axial direction of the first rotating shaft 241 is larger than the area of ​​the mounting through hole, the first connecting through hole, the second connecting through hole and the third connecting through hole. The first rotating shaft 241 can be limited by the two first limiting portions 243 to prevent the first rotating shaft 241 from escaping from the mounting through hole, the first connecting through hole, the second connecting through hole and the third connecting through hole.

Specifically, the first display screen mounting portion 23 is used to connect the first display screen 3. For example, a plurality of fixing through holes are provided on the second mounting plate 232. Screws pass through the fixing through holes and are threadedly engaged with the first display screen 3 to fix the first display screen 3 to the first display screen mounting portion 23.

[0090] Of course, in some other exemplary embodiments of the present disclosure, when the axial direction of the first rotating shaft structure 24 connecting the mounting seat 21 and the connecting portion 22 is arranged parallel to the axial direction of the first rotating shaft structure 24 connecting the first display screen mounting portion 23 and the connecting portion 22, refer to Fig. 9 As shown, the first hinge structure 2 may further include a second pivot structure 25, which is connected between the second end 2c and the first display screen 3, so that the first display screen 3 is rotatable relative to the second end 2c, that is, the second end 2c and the first display screen 3 are rotatably connected via the second pivot structure 25.

[0091] For example, refer to Fig. 9 As shown, a first fixing through hole is arranged on the second mounting plate 232 , a first fixing mounting plate 31 is arranged on the back of the first display screen 3 , and a second fixing through hole is arranged on the first fixing mounting plate 31 .

[0092] The second rotating shaft structure 25 may include a second rotating shaft 251 , a second elastic member 252 and two second limiting portions 253 ; the second rotating shaft 251 passes through a first fixing through hole and a second fixing through hole.

[0093] The two second limiting portions 253 are disposed at opposite ends of the second rotating shaft 251. The area of ​​the cross section of the second limiting portion 253 that is perpendicular to the axial direction of the second rotating shaft 251 is larger than the areas of the first fixing through hole and the second fixing through hole. The second rotating shaft 251 can be limited by the two second limiting portions 253 to prevent the second rotating shaft 251 from escaping from the first fixing through hole and the second fixing through hole.

[0094] The second elastic member 252 can be disposed between the two second limiting portions 253, and the second elastic member 252 can be compressed to increase the friction between the second limiting portion 253, the second mounting plate 232, and the first fixed mounting plate 31; for example, the second elastic member 252 can be disposed between the second limiting portion 253 and the second mounting plate 232, the second elastic member 252 can also be disposed between the second mounting plate 232 and the first fixed mounting plate 31, and the second elastic member 252 can also be disposed between the second limiting portion 253 and the first fixed mounting plate 31. After the second elastic member 252 is compressed, the friction between the second limiting portion 253, the second mounting plate 232, and the first fixed mounting plate 31 can be increased to fix the rotation position of the first display screen mounting portion 23.

[0095] In this example embodiment, the second rotating shaft 251 can be a bolt, the nut of the bolt is a second limiting portion 253, and the other second limiting portion 253 is a nut matched with the bolt. Of course, in some other example embodiments of the present disclosure, the second rotating shaft 251 can be a screw rod, and threads are provided at both ends of the screw rod, so that two nuts can be threadedly matched at both ends of the screw rod. In this case, the two nuts are two second limiting portions 253.

[0096] In this example embodiment, the second elastic member 252 may include a disc-shaped gasket, and the disc-shaped gasket may be provided in two pieces, and the two disc-shaped gaskets may be provided opposite to each other or opposite to each other. Of course, in some other example embodiments of the present disclosure, the second elastic member 252 may include a spring.

[0097] Moreover, the axial direction of the second rotating shaft structure 25 intersects with the axial direction of the first rotating shaft structure 24, that is, the second rotating shaft 251 of the second rotating shaft structure 25 intersects with the first rotating shaft 241 of the first rotating shaft structure 24. For example, the second rotating shaft 251 of the second rotating shaft structure 25 is perpendicular to the first rotating shaft 241 of the first rotating shaft structure 24. The second rotating shaft 251 of the second rotating shaft structure 25 can be perpendicular to the display surface of the first display screen 3, and the first rotating shaft 241 of the first rotating shaft structure 24 is parallel to the display surface of the first display screen 3, so that the rotation plane of the second rotating shaft structure 25 is perpendicular to the rotation plane of the first rotating shaft structure 24, that is, the first display screen 3 can be rotated 360 degrees on the display surface, increasing the rotation direction of the first display screen 3 to be suitable for more usage environments.

[0098] In this example implementation, refer to Figure 1 , Figure 2 and Fig.10 As shown, the bracket may further include a second hinge structure 4, and the second hinge structure 4 may include at least two second parts 4a and a third rotating shaft structure, that is, the second hinge structure 4 may include two second parts 4a, and the second hinge structure 4 may include three second parts 4a or more second parts 4a. The following description is made by taking the second hinge structure 4 including two second parts 4a as an example.

[0099] The two second parts 4 a of the second hinge structure 4 may include: a supporting portion 41 and a second display screen mounting portion 42 , and the supporting portion 41 is connected to the second display screen mounting portion 42 .

[0100] Reference Fig.10As shown, the support portion 41 may include a first support plate 411, a second support plate 412 and two first connecting ears 413. The first support plate 411 is vertically arranged with the second support plate 412, and one end of the first support plate 411 is connected with one end of the second support plate 412 to basically form an "L" shape. The first connecting ear 413 is connected to the side of the first support plate 411 away from the second support plate 412, and the first connecting ear 413 and the first support plate 411 are also vertically arranged, and the first connecting ear 413 and the second support plate 412 are also vertically arranged. A first through hole is arranged on the support portion 41. Specifically, the first connecting ear 413 is arranged with a first through hole (the first through hole is penetrated by the third shaft structure 43). Fig.10 not shown).

[0101] Reference Fig.10 As shown, the second display screen mounting portion 42 may include a third mounting plate 421 and two second connecting ears 422. The two second connecting ears 422 are connected to opposite ends of the third mounting plate 421, and the second connecting ears 422 and the third mounting plate 421 are also arranged vertically, so that the second display screen mounting portion 42 forms a "[" shape. The second display screen mounting portion 42 is provided with a second through hole. Specifically, the second connecting ear 422 is provided with a second through hole (the second through hole is penetrated by the third shaft structure 43). Fig.10 not shown).

[0102] The second hinge structure 4 has a third end 4b and a fourth end 4c that are arranged opposite to each other. Specifically, the end of the support part 41 away from the second display screen mounting part 42 is the third end 4b, and the end of the second display screen mounting part 42 away from the support part 41 is the fourth end 4c. The third end 4b is detachably connected to the base 1, that is, the end of the support part 41 away from the second display screen mounting part 42 is detachably connected to the base 1. Specifically, a through groove is provided on the first fixing plate 211 of the mounting seat 21. The first supporting plate 411 of the support part 41 can be inserted into the through groove on the first fixing plate 211 and then inserted into the bar groove 121 on the fixing seat 12, and then fixed by screws, so that the end of the support part 41 away from the second display screen mounting part 42 is detachably connected to the base 1, so that the second hinge structure 4 can be removed from the bracket together with the second display screen 5 and used separately.

[0103] Moreover, refer to Figure 4 As shown, a flange structure 213 is provided on one side of the first fixing plate 211 of the mounting seat 21 of the first hinge structure 2. The flange structure 213 can be set to an "L" shape, and the second support plate 412 can be fixed to the flange structure 213 by screws.

[0104] The fourth end 4c is used to fix the second display screen 5, that is, the end of the second display screen mounting portion 42 away from the supporting portion 41 fixes the second display screen 5. Specifically, a plurality of through holes are provided in the third mounting plate 421, and the second display screen 5 can be fixed to the third mounting plate 421 by screws.

[0105] Reference Fig.10 As shown, two adjacent second parts 4a of the second hinge structure 4 are rotatably connected via a third pivot structure 43, that is, the support portion 41 and the display screen mounting portion are rotatably connected via the third pivot structure 43, specifically, the two first connecting ears 413 and the two second connecting ears 422 are rotatably connected via the third pivot structure 43.

[0106] The third rotating shaft structure 43 may include a third rotating shaft 431 , a third elastic member 432 and two third limiting portions 433 ; the third rotating shaft 431 passes through the first through hole and the second through hole.

[0107] The two third limiting portions 433 are disposed at opposite ends of the third rotating shaft 431. The area of ​​the cross section of the third limiting portion 433 that is perpendicular to the axial direction of the third rotating shaft 431 is larger than the areas of the first through hole and the second through hole. The third rotating shaft 431 can be limited by the two third limiting portions 433 to prevent the third rotating shaft 431 from escaping from the first through hole and the second through hole.

[0108] The third elastic member 432 can be arranged between the two third limiting portions 433, and the third elastic member 432 can be compressed to increase the friction between the third limiting portion 433 and the second portion 4a; specifically, the third elastic member 432 can be arranged between the third limiting portion 433 and the second connecting ear 422, and the third elastic member 432 can be compressed to increase the friction between the third limiting portion 433 and the second connecting ear 422, so that the rotation position of the second display screen mounting portion 42 is fixed. Of course, the third elastic member 432 can be arranged between the second connecting ear 422 and the first connecting ear 413; the third elastic member 432 can also be arranged between the first connecting ear 413 and the third limiting portion 433, and similarly, the third elastic member 432 can be compressed to increase the friction, so that the rotation position of the second display screen mounting portion 42 is fixed.

[0109] In this example embodiment, the third rotating shaft 431 may be a bolt, the nut of the bolt is a third limiting portion 433, and the other third limiting portion 433 is a nut matched with the bolt. Of course, in some other example embodiments of the present disclosure, the third rotating shaft 431 may be a screw rod, and threads are provided at both ends of the screw rod, so that two nuts can be threadedly matched at both ends of the screw rod. In this case, the two nuts are two limiting portions.

[0110] In the present exemplary embodiment, the third elastic member 432 may include a disc-shaped gasket. Two disc-shaped gaskets may be provided, and the two disc-shaped gaskets may be arranged oppositely or back-to-back. Of course, in some other exemplary embodiments of the present disclosure, the third elastic member 432 may include a spring.

[0111] In the present exemplary embodiment, referring to Fig.11 As shown, the distance between the end face of the third end 4b and the first through hole 4131 is a first distance L1, and the distance between the supporting end of the second display screen 5 and the first through hole 4131 is a second distance L2.

[0112] Since the third end 4b is detachably connected to the base 1, the second hinge structure 4 and the second display screen 5 can be detached from the base 1 and placed separately for use, increasing the usage modes of the bracket. In this case, the second hinge structure 4 and the second display screen 5 form an "inverted V" shaped supporting structure to support the second display screen 5. Therefore, the supporting end of the second display screen 5 is the end for supporting the second display screen 5.

[0113] The ratio of the first distance L1 to the second distance L2 is greater than or equal to 0.8 and less than or equal to 2. For example, the ratio of the first distance L1 to the second distance L2 may be 0.82, 0.85, 0.87, 0.9, 0.93, 0.95, 0.98, 1.0, 1.02, 1.05, 1.07, 1.1, 1.13, 1.15, 1.18, 1.2, 1.25, 1.3, 1.35, 1.4, 1.45, 1.5, 1.55, 1.6, 1.65, 1.7, 1.75, 1.8, 1.85, 1.9, 1.95, and so on.

[0114] If the ratio of the first distance L1 to the second distance L2 is too large, such that the distance L1 between the end face of the third end 4b and the first through hole is too large, while the distance L2 between the supporting end of the second display screen 5 and the first through hole is too small, the second display screen 5 cannot be well supported.

[0115] If the ratio of the first distance L1 to the second distance L2 is too small, such that the distance L1 between the end face of the third end 4b and the first through hole is too small, while the distance L2 between the supporting end of the second display screen 5 and the first through hole is too large, the adjustment range of the inclination angle of the second display screen 5 is limited, which is not conducive to the user's viewing.

[0116] The above numerical range not only ensures that the second display screen 5 can be well supported, but also ensures that the adjustment range of the inclination angle of the second display screen 5 is relatively large, suitable for the user's viewing in various usage states.

[0117] Referring to Figure 11-Figure 14 As shown, the inclination angle of the second display screen 5 gradually increases.

[0118] In some other exemplary embodiments of the present disclosure, referring to Fig.15 As shown, the second hinge structure 4 may further include a fourth pivot structure 44, which is connected between the fourth end 4c and the second display screen 5, so that the second display screen 5 is rotatable relative to the fourth end 4c, that is, the fourth end 4c and the second display screen 5 are rotatably connected via the fourth pivot structure 44.

[0119] For example, refer to Fig.15 As shown, a third fixing through hole is arranged on the third mounting plate 421 , a second fixing mounting plate 51 is arranged on the back of the second display screen 5 , and a fourth fixing through hole is arranged on the second fixing mounting plate 51 .

[0120] The fourth rotating shaft structure 44 may include a fourth rotating shaft 441 , a fourth elastic member 442 and two fourth limiting portions 443 ; the fourth rotating shaft 441 passes through the third fixing through hole and the fourth fixing through hole.

[0121] The two fourth limiting portions 443 are disposed at opposite ends of the fourth rotating shaft 441. The area of ​​the cross section of the fourth limiting portion 443 that is perpendicular to the axial direction of the fourth rotating shaft 441 is larger than the areas of the third fixing through hole and the fourth fixing through hole. The fourth rotating shaft 441 can be limited by the two fourth limiting portions 443 to prevent the fourth rotating shaft 441 from escaping from the third fixing through hole and the fourth fixing through hole.

[0122] The fourth elastic member 442 may be disposed between the two fourth limiting portions 443, and the fourth elastic member 442 may be compressed to increase the friction between the fourth limiting portion 443, the third mounting plate 421, and the second fixed mounting plate 51; for example, the fourth elastic member 442 may be disposed between the fourth limiting portion 443 and the third mounting plate 421, the fourth elastic member 442 may also be disposed between the third mounting plate 421 and the second fixed mounting plate 51, and the fourth elastic member 442 may also be disposed between the fourth limiting portion 443 and the second fixed mounting plate 51. After the fourth elastic member 442 is compressed, the friction between the fourth limiting portion 443, the third mounting plate 421, and the second fixed mounting plate 51 may be increased, so that the rotation position of the second display screen mounting portion 42 is fixed.

[0123] In this example embodiment, the fourth rotating shaft 441 may be a bolt, the nut of the bolt is a fourth limiting portion 443, and the other fourth limiting portion 443 is a nut matched with the bolt. Of course, in some other example embodiments of the present disclosure, the fourth rotating shaft 441 may be a screw rod, and threads are provided at both ends of the screw rod, so that two nuts can be threadedly matched at both ends of the screw rod. In this case, the two nuts are two fourth limiting portions 443.

[0124] In this example embodiment, the fourth elastic member 442 may include a disc-shaped gasket, and the disc-shaped gasket may be provided in two pieces, and the two disc-shaped gaskets may be provided opposite to each other or opposite to each other. Of course, in some other example embodiments of the present disclosure, the fourth elastic member 442 may include a spring.

[0125] Moreover, the axial direction of the fourth rotating shaft structure 44 intersects with the axial direction of the third rotating shaft structure 43, that is, the fourth rotating shaft 441 of the fourth rotating shaft structure 44 intersects with the third rotating shaft 431 of the third rotating shaft structure 43. For example, the fourth rotating shaft 441 of the fourth rotating shaft structure 44 is perpendicular to the third rotating shaft 431 of the third rotating shaft structure 43. The fourth rotating shaft 441 of the fourth rotating shaft structure 44 can be perpendicular to the display surface of the second display screen 5, and the third rotating shaft 431 of the third rotating shaft structure 43 is parallel to the display surface of the second display screen 5, so that the rotation plane of the fourth rotating shaft structure 44 is perpendicular to the rotation plane of the third rotating shaft structure 43, that is, the second display screen 5 can be rotated 360 degrees on the display surface, increasing the rotation direction of the second display screen 5 to be suitable for more usage environments.

[0126] Based on the same inventive concept, the exemplary embodiment of the present disclosure provides a cash register, referring to Figure 1 As shown, the cash register may include a bracket and a first display screen 3, and the bracket is any of the brackets described above; the specific structure of the bracket has been described in detail above, so it is not repeated here. The first display screen 3 is connected to the first hinge structure 2 of the bracket. The first display screen 3 can be a currently existing display screen, for example, the first display screen 3 can be a liquid crystal display screen, or an OLED (Organic Electroluminescence Display, organic light-emitting semiconductor) display screen.

[0127] In some exemplary embodiments of the present disclosure, when the bracket further includes a second hinge structure 4, the cash register may further include a second display screen 5, and the second display screen 5 is connected to the second hinge structure 4. The second display screen 5 may be an existing display screen, for example, the second display screen 5 may be a liquid crystal display screen, or an OLED (Organic Electroluminescence Display, organic light emitting semiconductor) display screen.

[0128] Reference Figure 16-Figure 18 As shown, the first display screen 3 and the second display screen 5 can be adjusted to form a variety of tilt angles, which increases the adjustment range of the first display screen 3 and the second display screen 5 and expands the ease of use of the first display screen 3 and the second display screen 5 to be suitable for a variety of different usage environments.
