Description

Technical Field

[0001] The invention relates to a rotating shaft structure, and in particular to a rotating shaft structure applied to an electronic device with adjustable angle. Background Art

[0002] Generally speaking, electronic devices with adjustable angles are commonly found in monitoring equipment, such as image capture devices, motion sensing devices, or lighting devices. Since monitoring equipment must capture images, detect, or provide lighting for a large area, the related electronic devices must have a hinge structure with adjustable angles. Specifically, electronic devices related to monitoring equipment usually include two main components, namely a main device and a mounting base. The main device is, for example, a camera, a motion sensing module, or a lighting lamp. The mounting base is often set on a wall or a ceiling, so the mounting base is generally a fixing part. The main device and the mounting base are connected by a hinge structure.

[0003] A common shaft structure includes two shafts that are detachably and rotatably connected to each other. The two shafts are connected to the main device and the mounting base respectively. The two shafts can rotate relative to each other to adjust the angle of the main device, thereby monitoring or providing lighting for a specific area. After adjusting the angle, the two shafts are usually fixed with fixing parts (such as screws or buckles) to fix the angle of the main device.

[0004] When it is necessary to adjust to another angle, the fixings must be loosened first to separate the two shafts before the angle can be adjusted again. However, the shaft structure has wires for electrical connection inside. If the two shafts fall when separated, the wires inside will be pulled and even damaged. Alternatively, if the electronic device is damaged by external force, causing one of the shafts to fall together with the main device, the wires may also be damaged, which is necessary for improvement. Summary of the invention

[0005] In view of the above problems, the main purpose of the present invention is to provide an electronic device and a hinge structure with adjustable angle, and to solve the problem of wire damage that may occur when the hinge of the existing hinge structure is separated by the structure of the limiter and the fixing member of the hinge structure.

[0006] To achieve the above-mentioned purpose, the present invention provides a shaft structure, which is applied to an electronic device with adjustable angle. The shaft structure includes a first shaft, a second shaft, a limiter and a fixing member. The first shaft includes a through hole and a first connection surface. The second shaft includes a second connection surface. The second connection surface is connected to the first connection surface. The limiter is arranged between the first shaft and the second shaft. The limiter includes a body, a hollow part and a limiter. The hollow part passes through the body, and the hollow part corresponds to the through hole. The limiter is located on the inner wall of the hollow part and close to one side of the first shaft. The fixing member includes a head, a rod and a threaded part. The rod is located between the head and the threaded part, and the outer diameter of the threaded part is greater than the outer diameter of the rod. The rod and the threaded part are placed in the through hole, the head is located outside the through hole, and the threaded part passes through the hollow part and is connected to the second shaft. When the first shaft is separated from the second shaft, one end of the threaded part close to the rod abuts against the limiter.

[0007] To achieve the above-mentioned purpose, the present invention further provides an electronic device with adjustable angle, which includes a first shell, a second shell and a rotating shaft structure. The rotating shaft structure includes a first rotating shaft, a second rotating shaft, a stopper and a fixing member. One end of the first rotating shaft is connected to the first shell. The first rotating shaft includes a through hole and a first connecting surface. One end of the second rotating shaft is connected to the second shell, and the second rotating shaft includes a second connecting surface. The second connecting surface is connected to the first connecting surface. The stopper is arranged between the first rotating shaft and the second rotating shaft. The stopper includes a main body, a hollow part and a stopper. The hollow part passes through the main body, and the hollow part corresponds to the through hole. The stopper is located on the inner wall of the hollow part and close to one side of the first rotating shaft. The fixing member includes a head, a rod and a threaded part. The rod is located between the head and the threaded part, and the outer diameter of the threaded part is greater than the outer diameter of the rod. The rod and the threaded part are inserted into the through hole, the head is located on the outside of the through hole, and the threaded part passes through the hollow part and is connected to the second rotating shaft. When the first rotating shaft is separated from the second rotating shaft, one end of the threaded portion close to the rod portion abuts against the limiting portion.

[0008] According to an embodiment of the present invention, when the fixing member is rotated in a predetermined direction, the threaded portion is screwed to the second shaft. When the fixing member is rotated in the opposite direction, the rod moves out of the hollow portion, the first shaft is separated from the second shaft, and one end of the threaded portion close to the rod abuts against the limiting portion.

[0009] According to an embodiment of the present invention, the stopper is arranged on the second connection surface of the second rotating shaft. The second rotating shaft further comprises a locking hole, which is communicated with the hollow portion.

[0010] According to an embodiment of the present invention, the stopper further includes a first positioning portion connected to the main body. The second rotating shaft further includes a second positioning portion located on the second connecting surface and adjacent to the locking hole. The first positioning portion is connected to the second positioning portion.

[0011] According to an embodiment of the present invention, the hollow portion includes a neck section and a moving section. The neck section corresponds to the limiting portion. The inner diameter of the neck section is smaller than the inner diameter of the moving section, and the outer diameter of the threaded portion is larger than the inner diameter of the neck section.

[0012] According to an embodiment of the present invention, when one end of the threaded portion abuts against the limiting portion, the distance between the first connecting surface and the second connecting surface is substantially equal to the height of the moving section.

[0013] According to an embodiment of the present invention, the first rotating shaft further comprises a first annular tooth groove, which is located on the first connecting surface. The second rotating shaft further comprises a second annular tooth groove, which is located on the second connecting surface. The first annular tooth groove and the second annular tooth groove are meshed with each other.

[0014] According to an embodiment of the present invention, the first annular tooth groove includes a plurality of tooth structures, and the tooth structures are arranged at intervals. The height of the moving section is greater than the width of one of the tooth structures.

[0015] According to an embodiment of the present invention, the through hole and the fixing member are located at the center of the first annular tooth groove.

[0016] According to an embodiment of the present invention, the rotating shaft structure further includes a first waterproof ring. The first waterproof ring is disposed between the first connecting surface of the first rotating shaft and the second connecting surface of the second rotating shaft.

[0017] According to an embodiment of the present invention, the first waterproof ring is disposed on the first connecting surface of the first rotating shaft. The second rotating shaft further includes a convex portion, which presses against the first waterproof ring.

[0018] According to an embodiment of the present invention, the rotating shaft structure further comprises a second waterproof ring. The second waterproof ring is arranged at the periphery of the through hole of the first rotating shaft, and the head of the fixing member presses against the second waterproof ring.

[0019] According to an embodiment of the present invention, an electronic device with adjustable angle includes a first housing and a second housing, wherein one end of a first rotating shaft is connected to the first housing, and one end of a second rotating shaft is connected to the second housing.

[0020] According to an embodiment of the present invention, the rotating shaft structure further includes at least two third waterproof rings, which are respectively arranged between the first rotating shaft and the first housing, and between the second rotating shaft and the second housing.

[0021] As described above, according to the adjustable electronic device and its shaft structure of the present invention, the shaft structure includes a first shaft, a second shaft, a limiter and a fixing member. The limiter is arranged between the first shaft and the second shaft. The limiter includes a main body, a hollow part and a limiter. The hollow part passes through the main body, and the limiter is located on the inner wall of the hollow part and close to one side of the first shaft. The fixing member includes a head, a rod and a threaded part. The rod is located between the head and the threaded part, and the outer diameter of the threaded part is greater than the outer diameter of the rod. Therefore, the threaded part passes through the hollow part and is connected to the second shaft, so that the first shaft and the second shaft are fixed to each other. When the first shaft is separated from the second shaft, one end of the threaded part abuts against the limiter, so that the limiter can limit the fixing member and the first shaft. By means of the above structure, the distance when the first shaft or the second shaft is separated can be limited, thereby avoiding the situation of pulling the internal wire and avoiding the effect of damaging the wire.

[0030] In order to better understand the technical content of the present invention, preferred specific embodiments are described below.

[0031] Figure 1is a schematic diagram of an electronic device with adjustable angle according to an embodiment of the present invention, Figure 2 for Figure 1 The cross-sectional view of the electronic device with adjustable angle shown in FIG. Figure 3 for Figure 2 An enlarged schematic diagram of the rotating shaft structure is shown. Figure 4 for Figure 1 Please refer to the exploded diagram of the adjustable angle electronic device shown in the figure. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown. First, the angle-adjustable electronic device 1 (hereinafter referred to as the electronic device 1) of this embodiment is mainly used in monitoring equipment, which can be, for example, an image capture device, a motion sensing device, or a lighting device. Among them, the electronic device 1 includes a first shell 10, a second shell 20 and a hinge structure 30. The first shell 10 can be a mounting base, and the second shell 20 can be a shell of a main device. For example, if the electronic device 1 is an image capture device, the first shell 10 can be a mounting base mounted on a wall, a ceiling, or other fixed objects, and the second shell 20 can be the shell of a camera with an image capture function. In other embodiments, the configuration can also be reversed, and the present invention is not limited. In addition, the hinge structure 30 is used to connect the first shell 10 and the second shell 20, so that the second shell 20 can rotate relative to the first shell 10, thereby adjusting the angle between the second shell 20 and the first shell 10.

[0032] Specifically, the shaft structure 30 includes a first shaft 31, a second shaft 32, a stopper 33 and a fixing member 34. One end of the first shaft 31 is connected to the first housing 10, and one end of the second shaft 32 is connected to the second housing 20. Preferably, the first housing 10 has a first sleeve 11, and the second housing 20 has a second sleeve 21. In addition, one end of the first shaft 31 and one end of the second shaft 32 are cylinders respectively. The first sleeve 11 is sleeved on the outer side of the cylinder of the first shaft 31, so that the first housing 10 can rotate with the first shaft 31 as the axis, as shown in FIG. Figure 1 Similarly, the second sleeve 21 is sleeved on the outer side of the cylinder of the second rotating shaft 32, so that the second housing 20 can rotate around the second sleeve 21 as the axis. Figure 1 As shown by the arrow symbol on the right.

[0033] In addition, the first rotating shaft 31 includes a first connecting surface 311, and the second rotating shaft 32 includes a second connecting surface 321. The first connecting surface 311 is located on the surface of the first rotating shaft 31, and the second connecting surface 321 is located on the surface of the second rotating shaft 32 that can correspond to the first connecting surface 311. In this embodiment, the first connecting surface 311 is located on the lower surface of the first rotating shaft 31, and the second connecting surface 321 is located on the upper surface of the second rotating shaft 32. When assembling the rotating shaft structure 30, the first connecting surface 311 of the first rotating shaft 31 can correspond to the second connecting surface 321 of the second rotating shaft 32, and the first rotating shaft 31 and the second rotating shaft 32 can be fixed by the fixing member 34. Therefore, the second connecting surface 321 is connected to the first connecting surface 311, and the first rotating shaft 31 can rotate relative to the second rotating shaft 32 with the fixing member 34 as the axis, or the second rotating shaft 32 can rotate relative to the first rotating shaft 31 with the fixing member 34 as the axis, such as Figure 1 The first rotating shaft 31 or the second rotating shaft 32 rotates around the fixing member 34 as the axis, thereby adjusting the angle between the first shell 10 and the second shell 20.

[0034] In this embodiment, the first rotating shaft 31 further includes a through hole 312, and the fixing member 34 can pass through the through hole 312 and the stopper 33 to be connected to the second rotating shaft 32. Specifically, the stopper 33 is disposed between the first rotating shaft 31 and the second rotating shaft 32. In this embodiment, the stopper 33 is disposed on the second connecting surface 321 of the second rotating shaft 32. Figure 5 for Figure 4 For the cross-sectional diagram of the stopper and fixing parts shown in Figure 3 , Figure 4 and Figure 5 As shown. The limiting member 33 of this embodiment includes a main body 331, a hollow portion 332 and a limiting portion 333. The hollow portion 332 passes through the main body 331, and the hollow portion 332 corresponds to the through hole 312 of the first rotating shaft 31. The limiting portion 333 is located on the inner wall of the hollow portion 332 and close to one side of the first rotating shaft 31. In this embodiment, the limiting portion 333 is a convex portion extending from the inner wall of the hollow portion 332 to the middle, so that the hollow portion 332 can be divided into two sections. Figure 5 As shown, the upper side of the hollow portion 332 (i.e., the side close to the first rotating shaft 31) has a smaller inner diameter, which is called the neck section 3321. The lower side of the hollow portion 332 has a larger inner diameter, which is called the moving section 3322. In other words, the hollow portion 332 of this embodiment includes the neck section 3321 and the moving section 3322. Among them, the neck section 3321 corresponds to the limiting portion 333, so the inner diameter of the neck section 3321 is smaller than the inner diameter of the moving section 3322.

[0035] In this embodiment, the fixing member 34 includes a head 341, a rod 342 and a threaded portion 343. The rod 342 is located between the head 341 and the threaded portion 343. The outer diameter of the head 341 is greater than the outer diameters of the rod 342 and the threaded portion 343, and the outer diameter of the head 341 is greater than the inner diameter of the through hole 312 of the first rotating shaft 31. In addition, the outer diameter of the threaded portion 343 is greater than the outer diameter of the rod 342. When assembling the fixing member 34, the rod 342 and the threaded portion 343 can be placed in the through hole 312, and the head 341 is located outside the through hole 312. The rod 342 and the threaded portion 343 pass through the through hole 312 and enter the hollow portion 332, and the threaded portion 343 at the bottom passes through the hollow portion 332 and is connected to the second rotating shaft 32.

[0036] In the present embodiment, the second rotating shaft 32 and the limiting member 33 are made of a material that allows the threaded portion 343 to self-drill, such as plastic or metal. Specifically, the outer diameter of the threaded portion 343 of the present embodiment is larger than the neck section 3321 of the hollow portion 332, and smaller than the inner diameter of the moving section 3322 of the hollow portion 332. After the threaded portion 343 passes through the through hole 312, the fixing member 34 is rotated in a predetermined direction (e.g., clockwise) so that the threaded portion 343 can be locked into the inner wall of the neck section 3321 and enter the moving section 3322. Then, the fixing member 34 is continuously rotated so that the threaded portion 343 is screwed to the second rotating shaft 32. That is, when the fixing member 34 is rotated in the clockwise direction (i.e., the predetermined direction), the threaded portion 343 can pass through the hollow portion 332 and be screwed to the second rotating shaft 32, such as Figure 2 and Figure 3 shown.

[0037] Preferably, the second rotating shaft 32 of the present embodiment further includes a locking hole 322. The locking hole 322 is connected to the hollow portion 332 of the stopper 33, and the outer diameter of the threaded portion 343 is greater than the inner diameter of the locking hole 322. As mentioned above, after the threaded portion 343 passes through the hollow portion 332, the fixing member 34 is continuously rotated in a clockwise direction (i.e., a predetermined direction) so that the threaded portion 343 is locked into the locking hole 322. In other embodiments, the end of the threaded portion 343 may also be designed as a pointed head, so that it can be directly locked into the first rotating shaft 31 without the structure of the locking hole 322.

[0038] When the threaded portion 343 of the fixing member 34 is connected to the second rotating shaft 32 , the first rotating shaft 31 and the second rotating shaft 32 are fixed to each other, so that the angle between the first housing 10 and the second housing 20 is also fixed. Figure 6 for Figure 2 The schematic diagram of the first rotating shaft and the second rotating shaft being separated is shown in FIG. Figure 7 for Figure 6 Please refer to the enlarged schematic diagram of the shaft structure shown in Figure 6 and Figure 7When the first housing 10 and the second housing 20 need to be adjusted to other angles, the fixing member 34 must be loosened first and the first rotating shaft 31 and the second rotating shaft 32 are separated. For example, the fixing member 34 is rotated counterclockwise to rotate the fixing member 34 in the opposite direction. At this time, the fixing member 34 gradually moves out of the through hole 312. The rod 342 moves out of the hollow portion 332 until the threaded portion 343 is close to one end of the rod 342 and abuts against the stop portion 333, as shown in FIG. Figure 6 and Figure 7 As shown. At the same time, the first rotating shaft 31 is separated from the second rotating shaft 32. In addition, when the first rotating shaft 31 is separated from the second rotating shaft 32, since one end of the threaded portion 343 (close to the rod portion 342) abuts against the limiting portion 333, the separation distance of the first rotating shaft 31 or the second rotating shaft 32 can be limited. In other words, the limiting member 33 can limit the fixing member 34 and the first rotating shaft 31, thereby limiting the distance between the first connecting surface 311 and the second connecting surface 321 when the first rotating shaft 31 or the second rotating shaft 32 is separated.

[0039] The aforementioned structure limits the distance between the first rotating shaft 31 and the second rotating shaft 32 when they are separated, thereby preventing the internal wire 9 from being damaged. Specifically, the wire 9 for electrical connection is provided between the first housing 10 and the second housing 20, and passes through the interior of the rotating shaft structure 30. That is, the wire 9 passes through the first rotating shaft 31 and the second rotating shaft 32, as shown in FIG. Figure 2 and Figure 3 As shown. By limiting the position of the fixing member 34 and the first rotating shaft 31 by the limiting member 33, it is also possible to prevent the first rotating shaft 31 or the second rotating shaft 32 from being separated by a large distance and pulling the internal wire 9 to cause damage. Alternatively, if the electronic device 1 is damaged by external force, the structure of the limiting member 33 and the fixing member 34 can also prevent the second rotating shaft 32 from falling together with the second housing 20 (i.e., the main device), thereby preventing the internal wire 9 from being damaged.

[0040] Figure 8 for Figure 4 Please refer to the schematic diagram of the rotating shaft structure at another angle. Figure 4 and Figure 8As shown. In this embodiment, the first rotating shaft 31 also includes a first annular tooth groove 313, which is located on the first connecting surface 311. Correspondingly, the second rotating shaft 32 also includes a second annular tooth groove 323, which is located on the second connecting surface 321. The first annular tooth groove 313 and the second annular tooth groove 323 are meshed with each other, so that the first connecting surface 311 is rotatably connected to the second connecting surface 321, so as to adjust the angle between the first rotating shaft 31 and the second rotating shaft 32. Specifically, the first annular tooth groove 313 includes a plurality of tooth structures 3131, and the tooth structures 3131 are arranged at intervals. Similarly, the second annular tooth groove 323 also includes a plurality of tooth structures 3231, and the tooth structures 3231 are arranged at intervals. The tooth structure 3131 of the first annular tooth groove 313 is accommodated between two adjacent tooth structures 3231 of the second annular tooth groove 323, so that the first annular tooth groove 313 and the second annular tooth groove 323 are meshed with each other.

[0041] Preferably, the through hole 312 is located at the center of the first annular tooth groove 313, that is, the center of the first annular tooth groove 313. Correspondingly, the stopper 33 is also disposed at the center of the second annular tooth groove 323, and the hollow portion 332 corresponds to the center position (that is, the center of the circle) of the second annular tooth groove 323. Therefore, after the fixing member 34 is inserted into the through hole 312 and the hollow portion 332, it can be located at the center position of the first annular tooth groove 313 and the second annular tooth groove 323, so that the rotation between the first rotating shaft 31 and the second rotating shaft 32 is smoother.

[0042] In this embodiment, when the first rotating shaft 31 is separated from the second rotating shaft 32 and one end of the threaded portion 343 abuts against the stop portion 333, the distance D (eg, Figure 7 ), which is substantially equal to the height H of the moving section 3322 (as shown Figure 5 ). In other words, the maximum separation distance D between the first rotating shaft 31 and the second rotating shaft 32 is substantially equal to the height H. Therefore, the height H of the moving section 3322 can be defined according to the expected distance D between the first connecting surface 311 and the second connecting surface 321 when the first rotating shaft 31 and the second rotating shaft 32 are separated. For example, if the expected distance D between the first connecting surface 311 and the second connecting surface 321 is 1 cm when the first rotating shaft 31 and the second rotating shaft 32 are separated, the height H of the moving section 3322 can be designed to be 1 cm. The height H of the moving section 3322 is greater than the width of one of the tooth structures 3131 of the first annular tooth groove 313 (or one of the tooth structures 3231 of the second annular tooth groove 323) to ensure that the fixing member 34 can be loosened to adjust the angle between the first rotating shaft 31 and the second rotating shaft 32.

[0043] Preferably, the limiting member 33 also includes a first positioning portion 334, which is connected to the main body portion 331. The first positioning portion 334 of this embodiment is arranged adjacent to the main body portion 331. Correspondingly, the second rotating shaft 32 also includes a second positioning portion 324, which is located on the second connecting surface 321 and adjacent to the locking hole 322. When the limiting member 33 is assembled to the second rotating shaft 32, the first positioning portion 334 can be first connected to the second positioning portion 324, and then the hollow portion 332 can be matched to the locking hole 322. In this embodiment, the first positioning portion 334 has a positioning hole, and the second positioning portion 324 corresponds to a positioning column, so that the first positioning portion 334 can pass through the second positioning portion 324 (i.e., the positioning column) through the positioning hole. In other embodiments, the first positioning portion 334 can also have a positioning column, and the second positioning portion 324 can correspond to a positioning hole, which is not limited by the present invention.

[0044] Preferably, the second positioning portion 324 of this embodiment is located between the locking hole 322 and the second annular tooth groove 323. Figure 4 As shown, along the radial direction of the second annular tooth groove 323, from the center position (i.e., the center of the circle) outward, there are the locking hole 322, the second positioning portion 324, and the second annular tooth groove 323. Preferably, the locking hole 322 is located at the center position (i.e., the center of the circle) of the second annular tooth groove 323. Since the second positioning portion 324 is located between the locking hole 322 and the second annular tooth groove 323, when the first positioning portion 334 is assembled and connected to the second positioning portion 324, the rotation of the first annular tooth groove 313 and the second annular tooth groove 323 will not be affected.

[0045] Preferably, the first positioning portion 334 may further have a locking hole for a screw to pass through, thereby fixing the stopper 33 to the second rotating shaft 32 by screw locking. In other embodiments, the stopper 33 may be fixed to the second rotating shaft 32 by bonding. In other embodiments, the stopper 33 and the second rotating shaft 32 may be an integrally formed structure. For example, the stopper 33 and the second rotating shaft 32 may be formed simultaneously by injection molding. In addition, the second rotating shaft 32 and the stopper 33 of different materials may also be formed simultaneously by double-material injection, which is not limited by the present invention.

[0046] Preferably, the rotating shaft structure 30 may include a plurality of waterproof rings, which are disposed on the first rotating shaft 31 or the second rotating shaft 32, or between the two, to prevent moisture from entering the rotating shaft structure 30. In this embodiment, the waterproof rings are disposed at the first, second, and third waterproof rings. Figure 3 and Figure 7As shown, the rotating shaft structure 30 further includes a first waterproof ring 35. The first waterproof ring 35 is disposed between the first connection surface 311 of the first rotating shaft 31 and the second connection surface 321 of the second rotating shaft 32 to prevent moisture from entering the rotating shaft structure 30 from between the first connection surface 311 and the second connection surface 321. In this embodiment, the first waterproof ring 35 is disposed on the first connection surface 311 of the first rotating shaft 31. Preferably, the second rotating shaft 32 further includes a convex portion 325. The convex portion 325 is located on the second connection surface 321, so that the convex portion 325 can press against the first waterproof ring 35, as shown in FIG. Figure 3 As shown. The convex portion 325 interferes with the first waterproof ring 35 to increase the waterproof effect. Preferably, the convex portion 325 can be a ring-shaped structure (such as Figure 4 As shown), the annular structure of the first waterproof ring 35 corresponds to the annular structure of the first waterproof ring 35. The annular protrusion 325 can be in full contact with the first waterproof ring 35, which can further improve the waterproof effect.

[0047] In other embodiments, the first waterproof ring 35 and the convex portion 325 may also be configured in reverse. Specifically, the first waterproof ring 35 may also be disposed on the second connection surface 321 of the second rotating shaft 32. Correspondingly, the first rotating shaft 31 has a convex portion 325 located on the first connection surface 311 for abutting against the first waterproof ring 35.

[0048] In addition, the rotating shaft structure 30 further includes a second waterproof ring 36. The second waterproof ring 36 is disposed at the periphery of the through hole 312 of the first rotating shaft 31. Preferably, the inner wall of the through hole 312 has a groove, and the second waterproof ring 36 is accommodated in the groove. When the fixing member 34 is inserted into the through hole 312, the head 341 of the fixing member 34 presses against the second waterproof ring 36 to prevent moisture from entering the rotating shaft structure 30 from the through hole 312 of the first rotating shaft 31.

[0049] In addition, if Figure 2 and Figure 6 As shown, the rotating shaft structure 30 further includes at least two third waterproof rings 37. The third waterproof rings 37 are respectively disposed between the first rotating shaft 31 and the first housing 10, and between the second rotating shaft 32 and the second housing 20. In other words, in this embodiment, the waterproof rings disposed between the first rotating shaft 31 and the first housing 10, and between the second rotating shaft 32 and the second housing 20 are referred to as third waterproof rings 37. The third waterproof rings 37 can prevent moisture from entering the rotating shaft structure 30 from the connection between the first housing 10 or the second housing 20.

[0050] In addition, the present invention also provides a hinge structure, which is applied to an electronic device with adjustable angle. The specific structure of the hinge structure and its connection relationship with the electronic device can be directly referred to the above embodiments, and no further description is given here.

[0051] In summary, according to the adjustable electronic device and its shaft structure of the present invention, the shaft structure includes a first shaft, a second shaft, a limiter and a fixing member. The limiter is arranged between the first shaft and the second shaft. The limiter includes a main body, a hollow part and a limiter. The hollow part passes through the main body, and the limiter is located on the inner wall of the hollow part and close to one side of the first shaft. The fixing member includes a head, a rod and a threaded part. The rod is located between the head and the threaded part, and the outer diameter of the threaded part is greater than the outer diameter of the rod. Therefore, the threaded part passes through the hollow part and is connected to the second shaft, so that the first shaft and the second shaft are fixed to each other. When the first shaft is separated from the second shaft, one end of the threaded part abuts against the limiter, so that the limiter can limit the fixing member and the first shaft. By means of the above structure, the distance when the first shaft or the second shaft is separated can be limited, thereby avoiding the situation of pulling the internal wire and avoiding the effect of damaging the wire.

[0052] It should be noted that the above embodiments are provided for the purpose of illustration, and the scope of rights claimed by the present invention should be based on the claims, rather than being limited to the above embodiments.
