For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0051] In the embodiments shown in the drawings, directional indications (such as up, down, left, right, front, and back, etc.) are not absolute but relative when describing the structure and movement of each component, and are not used to limit the direction of the product in actual use.

[0052] In addition, in the description of the present application, ordinal numbers, such as "first", "second", etc., are only used to distinguish and describe related objects, and cannot be understood as indicating or implying the relative importance or order between the related objects.

[0053] like Figure 1 and Figure 2 As shown, the present application provides an embodiment of a rotating shaft, including a base 100, a lower connecting member 200, an upper connecting member 300 and a rotating member 400, the base 100 is provided with a first guide hole 101 extending along the height direction; the lower connecting member 200 is arranged in the base 100 and is rotatably connected to the base 100, and the lower connecting member 200 is provided with a limiting shaft 201; the upper connecting member 300 is arranged in the base 100, the upper end of the upper connecting member 300 is rotatably connected to the lower connecting member 200, and the lower end of the upper connecting member 300 is provided with a movable rotating shaft 301, and the movable rotating shaft 301 is movably arranged in the first guide hole 101; one end of the rotating member 400 is rotatably connected to the upper connecting member 300, the rotating member 400 has a second guide hole 401 extending along the length direction, and the limiting shaft 201 is movably arranged in the second guide hole 401.

[0054] Specifically, the lower connecting member 200, the upper connecting member 300 and the rotating member 400 are all arranged on the base 100, and the base 100 serves as a supporting member of the entire rotating shaft. A first guide hole 101 is arranged on the base 100 along the height direction. Figure 1 In the vertical direction, the movable shaft 301 of the upper connecting member 300 is movably arranged in the first guide hole 101, and the upper connecting member 300 is rotatably connected with the rotating member 400. When the rotating member 400 rotates, it drives the upper connecting member 300 to rotate, and at the same time drives the movable shaft 301 to move in the first guide hole 101, so that the position of the rotation connection point between the rotating member 400 and the upper connecting member 300 changes, thereby making the position of the rotation axis of the rotating member 400 variable. Figure 3 As shown, the approximate axis center of the rotating member 400 when it rotates 0 to 45 degrees is a, and the approximate axis center of the rotating member 400 when it rotates 45 to 90 degrees is b.

[0055] The rotating member 400 is provided with a second guide hole 401 along the length direction. For example, the length direction of the rotating member 400 is Figure 1 In the left and right directions, the limiting shaft 201 of the lower connecting member 200 is movably arranged in the second guide hole 401. When the rotating member 400 drives the upper connecting member 300 to rotate, it also drives the lower connecting member 200 to rotate, so that the limiting shaft 201 of the lower connecting member 200 moves along the second guide hole 401 in the second guide hole 401. The cooperation between the limiting shaft 201 and the second guide hole 401 can limit the rotation angle of the rotating member 400. The lower connecting member 200 is also rotatably connected to the base 100 and the upper connecting member 300 respectively. The lower connecting member 200 can also play the role of supporting the upper connecting member 300 to improve the stability of the upper connecting member 300 when rotating, thereby improving the stability of the rotating member 400 when rotating.

[0056] When the hinge is applied to an electronic device, the rotating member 400 is fixedly connected to the cover body 500 as a cover body bracket, and the rotating member 400 rotates synchronously with the cover body 500. The position of the rotation axis of the rotating member 400 is variable, that is, the rotation axis of the cover body 500 is variable. Therefore, when the cover body 500 is assembled on the shell 600, the influence of the structure of the shell 600 is reduced, and the rotatable angle of the cover body 500 relative to the shell 600 is increased, thereby improving the flexibility and meeting the use scenarios of horizontal or vertical electronic equipment, and having many applicable scenarios.

[0057] In a specific embodiment, in the initial state, the movable rotating shaft 301 is located at the lower end of the first guide hole 101, the limiting shaft 201 is located at the first end of the second guide hole 401, and the first end of the second guide hole 401 is the end of the second guide hole 401 away from the rotating member 400 and rotatably connected to the upper connecting member 300; when the rotating member 400 rotates to the maximum angle, the movable rotating shaft 301 is located at the upper end of the first guide hole 101, the limiting shaft 201 is located at the second end of the second guide hole 401, and the second end of the second guide hole 401 is the end of the second guide hole 401 close to the rotating member 400 and rotatably connected to the upper connecting member 300.

[0058] like Figure 4 As shown, in the initial position, that is, when the rotating member 400 is at the 0 degree position, the movable rotating shaft 301 of the upper connecting member 300 is located at the lower end of the first guide hole 101, and the limiting shaft 201 of the lower connecting member 200 is located at the first end of the second guide hole 401 (that is, the end away from the hinge point of the rotating member 400 and the upper connecting member 300). When the rotating member 400 rotates counterclockwise, the rotating member 400 drives the lower connecting member 200 to rotate and moves the limiting shaft 201 toward the second end of the second guide hole 401. At the same time, the rotating member 400 drives the upper connecting member 300 to rotate and moves the movable rotating shaft 301 toward the upper end of the second guide hole 401. When the rotating member 400 rotates to the maximum angle, the limiting shaft 201 of the lower connecting member 200 is located at the second end of the second guide hole 401, and the movable rotating shaft 301 of the upper connecting member 300 is located at the upper end of the first guide hole 101.

[0059] It should be noted that Figure 4 This is only an example of different rotation angles of the rotating member 400 . The maximum rotation angle of the rotating member 400 is not limited to 90 degrees. In practical applications, the rotation angle of the rotating member 400 can be greater than 90 degrees by increasing the length of the second guide hole 401 .

[0060] Further, such as Figure 5 As shown, a limiting protrusion 402 is protruded from the inner wall of the second guide hole 401 , and the limiting protrusion 402 is close to the second end of the second guide hole 401 . There is a preset distance between the limiting protrusion 402 and the second end of the second guide hole 401 to form a clamping space for clamping the movable rotating shaft 301 .

[0061] In practical applications, the size of the above-mentioned preset distance can be set according to the outer diameter of the limiting shaft 201, and is not limited here. As long as the limiting shaft 201 can be limited in the clamping space by the limiting protrusion 402 when it moves to the second end of the second guide hole 401, it is within the protection scope of the present application. When the limiting shaft 201 of the lower connecting member 200 moves to the second end of the second guide hole 401 and is limited in the clamping space by the limiting protrusion 402, the rotating member 400 can be kept at the maximum rotation angle, and then the cover body 500 can be kept at the maximum rotation angle, so that the user can operate it easily.

[0062] In a specific embodiment, Figure 6 As shown, the base 100 includes a support platform 110 and two side plates 120. The two side plates 120 are relatively arranged on both sides of the support platform 110 along the width direction. A recessed groove 111 is provided in the middle of the support platform 110. One end of the lower connecting member 200 is arranged on the support platform 110, and the other end of the lower connecting member 200 extends to the top of the recessed groove 111 along the length direction of the base 100 and is rotatably connected to the side plate 120. The lower end of the upper connecting member 300 is arranged in the recessed groove 111, and the upper end of the upper connecting member 300 is located above the support platform 110. A first guide hole 101 is provided in the area corresponding to the recessed groove 111 on the side plate 120, that is, the first guide hole 101 is connected to the recessed groove 111, so that the movable rotating shaft 301 arranged at the lower end of the upper connecting member 300 can extend into the first guide hole 101 and can move along the extension direction of the first guide hole 101.

[0063] Further, such as Figure 7 As shown, the lower connecting member 200 includes a lower connecting plate 210 and two lower connecting rods 220. The two lower connecting rods 220 are relatively arranged on both sides of the lower connecting plate 210 along the width direction. The lower connecting rods 220 are approximately "L-shaped" structures. The horizontal parts of the two lower connecting rods 220 are arranged on the support platform 110, and the vertical parts of the two lower connecting rods 220 are arranged above the concave groove 111. Figure 8 As shown, there is a distance between the two lower connecting rods 220 to form an accommodation space, and the lower end of the upper connecting member 300 can pass through the accommodation space between the two lower connecting rods 220 and then extend into the recessed groove 111 to improve the compactness of the structure and reduce the overall volume of the shaft.

[0064] The inner walls of the first ends of the two lower connecting rods 220 (the ends of the horizontal parts of the lower connecting rods 220 away from the vertical parts) are respectively provided with limiting shafts 201. In the initial state, the rotating member 400 is located between the two lower connecting rods 220 to improve the compactness of the structure. The two limiting shafts 201 are respectively located on both sides of the rotating member 400 along the width direction. The two limiting shafts 201 extend from both sides of the rotating member 400 into the second guide holes 401 of the rotating member 400.

[0065] The second ends (vertical parts) of the two lower connecting rods 220 extend to the top of the recessed groove 111 and are rotatably connected to the upper connecting member 300. The second ends (vertical parts) of the two lower connecting rods 220 are also rotatably connected to the two side plates 120 in a one-to-one correspondence. That is, the second end of one lower connecting rod 220 is rotatably connected to one side plate 120, and the second end of the other lower connecting rod 220 is rotatably connected to the other side plate 120.

[0066] For example, Figure 6 and Figure 7 As shown, the outer side walls of the second ends of the two lower connecting rods 220 are respectively provided with first rotating shafts 221, and the two side plates 120 are respectively provided with first mounting holes 121, and the two first rotating shafts 221 are rotatably connected with the two first mounting holes 121 in a one-to-one correspondence. Fig. 9 As shown, the outer side walls of the two upper connecting members 300 are respectively provided with a second rotation axis 302. Figure 7 As shown, the two lower connecting rods 220 are respectively provided with second mounting holes 222 , and the two second rotating shafts 302 are rotatably connected to the two second mounting holes 222 in a one-to-one correspondence.

[0067] As a simple variation, a first mounting hole may be provided on the lower connecting rod 220, and a first rotation axis may be provided on the side plate 120, so that the lower connecting rod 220 and the upper connecting member 300 can be rotatably connected. Similarly, a second mounting hole may be provided on the outer side wall of the upper connecting member 300, and a second rotation axis may be provided on the lower connecting rod 220, so as to realize the rotatable connection between the upper connecting member 300 and the lower connecting rod 220.

[0068] Further, such as Fig. 9 As shown, the upper connecting member 300 includes an upper connecting plate 310 and two upper connecting rods 320. The upper connecting rods 320 are approximately in the shape of a "7". The upper connecting rods 320 include a horizontal portion 321 and a vertical portion 322 that are connected to each other. One end of the upper connecting plate 310 is connected to the vertical portion 322 of one upper connecting rod 320, and the other end of the upper connecting plate 310 is connected to the vertical portion 322 of the other upper connecting rod 320.

[0069] The vertical parts 322 of the two upper connecting rods 320 are arranged in the concave groove 111 and the outer side walls are respectively provided with movable rotating shafts 301; the horizontal parts 321 of the two upper connecting rods 320 extend in the direction away from the lower connecting member 200 along the length direction. The horizontal parts 321 of the two upper connecting rods 320 are respectively rotatably connected with the rotating member 400. For example, the two outer side walls of the rotating member 400 arranged opposite to each other are respectively provided with third rotating shafts 403, and the horizontal parts 321 of the two upper connecting rods 320 are respectively provided with third mounting holes 303, and the two third rotating shafts 403 are rotatably connected with the two third mounting holes 303 in a one-to-one correspondence. In addition, the horizontal parts 321 of the two upper connecting rods 320 are respectively rotatably connected with the two lower connecting rods 220 in a one-to-one correspondence. For example, the outer side walls of the horizontal parts 321 of the two upper connecting rods 320 are respectively provided with second rotating shafts 302, and the two lower connecting rods 220 are respectively provided with second mounting holes 222, and the two second rotating shafts 302 are rotatably connected with the two second mounting holes 222 in a one-to-one correspondence. Among them, the first mounting hole 121 is arranged on one side of the first guide hole 101, the second mounting hole 222 and the first rotating axis 221 are both arranged on the vertical part of the lower connecting rod 220, and the second mounting hole 222 is arranged below the first rotating axis 221; the second rotating axis 302 and the third mounting hole 303 are both arranged on the horizontal part 321 of the upper connecting rod 320, and the second rotating axis 302 is arranged on the side of the third mounting hole 303 close to the vertical part.

[0070] The present application also provides a housing of an electronic device, such as Fig.10 and Fig.11 As shown, the cover 500, the housing 600 and the shaft described in any of the above embodiments are included, and the structure of the shaft is as follows Figures 1 to 9As shown, the base 100 is fixedly disposed on the housing 600, and the cover 500 is fixedly connected to the rotating member 400, so that the cover 500 can be opened and closed and is disposed on the housing 600. A receiving groove can be disposed on the housing 600, and the base 100 is installed in the receiving groove. The cover 500 is connected to the housing 600 through a rotating shaft, so that the cover 500 can be opened and closed and is disposed on the housing 600. When the cover body 500 is opened, the cover body 500 drives the rotating part 400 to rotate, and when the rotating part 400 rotates, it drives the upper connecting part 300 and the lower connecting part 200 to rotate. When the upper connecting part 300 rotates, the movable rotating shaft 301 of the upper connecting part 300 moves in the first guide hole 101, so that the rotation axis of the cover body 500 is variable, thereby reducing the influence of the cover body 500 structure on the rotation of the shell 600, and the rotatable angle of the cover body 500 relative to the shell 600 is increased, the flexibility is improved, and it can meet the horizontal or vertical use scenarios of the electronic device, and is applicable to many scenarios; when the lower connecting part 200 rotates, the limit shaft 201 of the lower connecting part 200 moves in the second guide hole 401, and the cooperation between the limit shaft 201 and the second guide hole 401 can limit the rotation angle of the rotating part 400. The lower connecting member 200 is also rotatably connected to the base 100 and the upper connecting member 300 respectively. The lower connecting member 200 can also support the upper connecting member 300 to improve the stability of the upper connecting member 300 during rotation, thereby improving the stability of the rotating member 400 and the cover body 500 during rotation.

[0071] The present application also provides an embodiment of an electronic device, comprising a device body and a housing of the electronic device described in the above embodiment, wherein the housing of the electronic device is as follows: Fig.10 and Fig.11 As shown, the device body is arranged in the shell 600, and the cover body 500 is opened and closed on the shell 600. When the cover body 500 is opened, the device body in the shell 600 can be inspected or parts can be replaced. The rotation angle of the cover body 500 is not affected by the structure of the shell 600, and the rotation angle of the cover body 500 can be increased to facilitate the inspection of the device body in the shell 600; when the cover body 500 is closed, it can protect the device body in the shell 600.

[0072] The electronic device in this embodiment may be a printer or a cash register, etc. By using the above-mentioned variable axis rotating shaft, the door cover can be opened 90 degrees, thereby satisfying the vertical or horizontal usage scenarios of the printer. The shape of the door cover does not need to be disassembled to meet the 90-degree opening. The door cover can be made into an integrated type to achieve a more personalized ID appearance.
