The fixing member is configured to maintain the first end in the first through-hole. The positioning member is connected to the second end and penetrates the second through-hole. The second bracket is rotatably mounted on the outside of the spindle.

[0006] In one or more embodiments of the present invention, the outer edge of the first end has a first flat edge, and the inner edge of the first through-hole has a second flat edge. The first flat edge and the second flat edge abut against each other.

[0007] In one or more embodiments of the present invention, the fixing member is a screw. The spindle further has a screw hole connected to the first end. The fixing member passes through the first through hole and is locked to the screw hole.

[0008] In one or more embodiments of the present invention, the screw hole is further connected to the second end. The fixing member and the positioning member are respectively two connected parts of the screw.

[0009] In one or more embodiments of the present invention, the screw hole has an internal thread portion that is away from the first end and adjacent to the second end.

[0010] In one or more embodiments of the present invention, the second end has a positioning hole, and the positioning member further penetrates and engages with the positioning hole.

[0011] In one or more embodiments of the present invention, the fixing member is located on a side of the first extension portion away from the spindle. The spindle and the fixing member are configured to be magnetically attracted to each other.

[0012] In one or more embodiments of the present invention, the spindle comprises a ferromagnetic material, and the fixing member is a magnet.

[0013] In one or more embodiments of the present invention, the fixing member abuts against the aforementioned side of the first extension portion away from the spindle and partially penetrates into the first through hole.

[0014] In one or more embodiments of the present invention, the fixing member includes a hook. The spindle further has a slot connected to the first end. The hook passes through the first through-hole and snaps into the slot.

[0015] In one or more embodiments of the present invention, the latching slot includes a first slot section and a second slot section. The first slot section connects between the first end and the second slot section. The second slot section expands outward relative to the first slot section to form a stepped portion.

[0022] In summary, in the hinge assembly of the present invention, the first end of the spindle is engaged with the first through-hole of the first extension portion of the first bracket, thereby limiting the rotation of the spindle relative to the first bracket. Furthermore, the positioning member connected to the second end of the spindle is inserted into the second through-hole of the second extension portion of the first bracket. In this way, the rotation centers of the first bracket and the second bracket sleeved on the outside of the spindle can be aligned with each other, and relative displacement of the two in the radial direction of the spindle can be prevented. In addition, the hinge assembly also uses a fixing member to prevent relative displacement of the spindle and the first bracket in the axial direction. Compared with the existing assembly method of the covering hinge, the hinge assembly of the present invention only needs to use one fixing member for assembly, so the appearance is relatively simple, and it is particularly suitable for use in electronic devices where it is not desired to have visible screws or rivets.

[0068] The following drawings illustrate various embodiments of the present invention. For clarity, many practical details are included in the following description. However, it should be understood that these practical details are not intended to limit the present invention. In other words, these practical details are not essential to some embodiments of the present invention. Furthermore, to simplify the drawings, some conventional structures and components are depicted in simplified schematic form.

[0069] Please refer to Figure 1A . Figure 1A FIG1 is a perspective view of an electronic device 100 according to an embodiment of the present invention. Figure 1A As shown, the electronic device 100 includes a first housing 110, a second housing 120, and a hinge assembly 200. The first housing 110 and the second housing 120 are connected via the hinge assembly 200 and can be rotated relative to each other via the hinge assembly 200. The electronic device 100 is exemplified by a notebook computer, in which the first housing 110 is the housing of the display and the second housing 120 is the housing of the host computer, but the present invention is not limited to this.

[0070] In practical applications, the electronic device 100 may be other types of electronic products, such as a photographic device, a motion sensing device, or a lighting device. Figure 1B , which is a perspective view illustrating a hinge assembly 200 according to one embodiment of the present invention applied to a photographic device, wherein the photographic device is, for example, a video conferencing sound bar and is represented by dotted lines.

[0071] Please refer to Figure 2A as well as Figure 2B . Figure 2A FIG1 is a perspective assembly diagram illustrating a hinge assembly 200 according to one embodiment of the present invention. Figure 2B To illustrate Figure 2A A partial exploded view of the hinge assembly 200 is shown in FIG. Figure 2A and Figure 2B As shown, the hinge assembly 200 includes a first bracket 210, a spindle 220 and a second bracket 250. The first bracket 210 includes a main body 211, a first extension 212 and a second extension 213. The first extension 212 and the second extension 213 are connected to the main body 211 and are opposite to each other. The spindle 220 is arranged between the first extension 212 and the second extension 213. The first bracket 210 and the spindle 220 do not rotate relative to each other. The second bracket 250 is rotatably mounted on the outside of the spindle 220. The second bracket 250 is, for example, a metal sheet punched into a tubular shape using a stamping process to cover the spindle 220, and the tightness and contact area of the covering are used to adjust the friction between the second bracket 250 and the spindle 220, thereby controlling the torsion of the hinge assembly 200. The first bracket 210 and the second bracket 250 are respectively fixed to Figure 1A The first shell 110 and the second shell 120 are connected. In this way, the first shell 110 and the second shell 120 can be turned relative to each other through the hinge assembly 200.

[0072] Specifically, if Figure 2A and Figure 2B As shown, the main body 211 is U-shaped. The first bracket 210 includes two pairs of first extensions 212 and second extensions 213, and these two pairs of first extensions 212 and second extensions 213 are respectively disposed at the two ends of the main body 211. Conversely, the hinge assembly 200 includes two pairs of spindles 220 and second brackets 250, and these two pairs of spindles 220 and second brackets 250 are respectively disposed at the two pairs of first extensions 212 and second extensions 213. By increasing the number of first extensions 212 and second extensions 213 combinations and the corresponding number of spindles 220 and second brackets 250 combinations, the stability of the hinge assembly 200 connecting the first housing 110 and the second housing 120 can be increased.

[0073] In practical applications, the main body 211 is not limited to Figure 2A The first bracket 210 may only include a pair of first extensions 212 and second extensions 213, and the hinge assembly 200 may only include a pair of spindles 220 and second brackets 250, but the purpose of relative rotation of the first shell 110 and the second shell 120 via the hinge assembly 200 can still be achieved.

[0074] Please refer to Figure 3 , which is a drawing Figure 2A The cross-sectional view of the hinge assembly 200 along line segment 3-3 is shown in FIG. Figure 2B and Figure 3 As shown, the first extension portion 212 and the second extension portion 213 have a first through-hole 212a and a second through-hole 213a, respectively. The spindle 220 has a first end 221 and a second end 222. The first end 221 penetrates and engages with the first through-hole 212a, preventing rotation relative to the first through-hole 212a. In other words, the first bracket 210 and the spindle 220 do not rotate relative to each other.

[0075] For example, if Figure 2B As shown, the mandrel 220 is cylindrical. The outer edge of the first end 221 of the mandrel 220 has a first flat edge 221a (formed, for example, by secondary machining during a cutting process). Furthermore, the inner edge of the first through-hole 212a of the first extension 212 has a second flat edge 212a1. The first flat edge 221a and the second flat edge 212a1 abut against each other. This prevents the first end 221 of the mandrel 220 from rotating relative to the first through-hole 212a.

[0076] In actual applications, in order to prevent the first end 221 of the core shaft 220 from rotating relative to the first through hole 212a, the outer edge of the first end 221 of the core shaft 220 and the inner edge of the first through hole 212a of the first extension portion 212 can be other matching shapes (for example, shapes other than a perfect circle).

[0077] like Figure 2B and Figure 3As shown, the hinge assembly 200 further includes a fixing member 230. The fixing member 230 is configured to maintain the first end 221 of the spindle 220 inserted into the first through-hole 212a of the first extension portion 212. Specifically, the fixing member 230 is a screw. The fixing member 230 includes a head 231 and an external threaded portion 232 connected to each other. The spindle 220 further has a screw hole 223 connected to the first end 221. The screw hole 223 has an internal threaded portion 223a. The head 231 of the fixing member 230 abuts against the side of the first extension portion 212 away from the spindle 220, while the external threaded portion 232 of the fixing member 230 passes through the first through-hole 212a and is locked to the internal threaded portion 223a of the screw hole 223. In this way, the first end 221 of the spindle 220 can be prevented from separating from the first through-hole 212a. In other words, relative displacement of the spindle 220 and the first bracket 210 in the axial direction is prevented.

[0078] like Figure 2B and Figure 3 As shown, the hinge assembly 200 further includes a positioning member 240. The positioning member 240 is connected to the second end 222 of the spindle 220 and penetrates the second through-hole 213a of the second extension portion 213. Specifically, the second end 222 has a positioning hole 222a. The positioning member 240 further penetrates and engages with the positioning hole 222a. By allowing the first end 221 of the spindle 220 to penetrate and engage with the first through-hole 212a of the first extension portion 212, and allowing the positioning member 240 to penetrate the second through-hole 213a of the second extension portion 213, the rotation centers of the first bracket 210 and the second bracket 250 sleeved on the outside of the spindle 220 can be aligned with each other, and relative displacement of the two in the radial direction of the spindle 220 can be prevented.

[0079] When assembling the hinge assembly 200, the following steps may be performed: (1) placing the combination of the spindle 220 and the second bracket 250 between the first extension portion 212 and the second extension portion 213 of the first bracket 210, and making the first end 221 and the second end 222 of the spindle 220 face the first through-hole 212a of the first extension portion 212 and the second through-hole 213a of the second extension portion 213, respectively; (2) moving the spindle 220 toward the first extension portion 212 so that the first end 221 of the spindle 220 passes through the first through-hole 212a of the first extension portion 212; (3) passing the positioning member 240 through the second through-hole 213a of the second extension portion 213 and connecting it to the positioning hole 222a at the second end 222 of the spindle 220; and (4) passing the fixing member 230 through the first through-hole 212a of the first extension portion 212 and locking it to the screw hole 223 connected to the first end 221 of the spindle 220.

[0080] As can be seen from the above description, compared to the existing assembly method of the covering hinge, the hinge assembly 200 of this embodiment only needs to use one fixing member 230 for assembly, so the appearance is relatively simple and is particularly suitable for application in electronic devices 100 where visible screws or rivets are not desired.

[0081] Please refer to Figure 4 as well as Figure 5 . Figure 4 FIG1 is a partial perspective exploded view of a hinge assembly 300 according to another embodiment of the present disclosure. Figure 5 To illustrate Figure 4 The cross-sectional view of the hinge assembly 300 after assembly. Figure 4 and Figure 5 As shown, the hinge assembly 300 includes a first bracket 210, a spindle 320, a fixing member 330, a positioning member 340 and a second bracket 250, wherein the first bracket 210 and the second bracket 250 are the same as Figure 2A The embodiment shown in FIG. 3 is a schematic diagram of a hinge assembly 300 of FIG. 3 , and the hinge assembly 300 of FIG. 3 is a schematic diagram of a hinge assembly 300 of FIG. 3 . Figure 2A 3. The differences between the embodiments shown in FIG. 3 and FIG. 4 are explained below. Specifically, in this embodiment, the screw hole 323 of the spindle 320 is further connected from the first end 321 to the second end 322. The fixing member 330 and the positioning member 340 are respectively two connected parts of a single screw. The fixing member 330 includes a connected head 331 and an external threaded portion 332. The positioning member 340 is connected to an end of the external threaded portion 332 away from the head 331. The external threaded portion 332 of the fixing member 330 is located in the screw hole 323, and the positioning member 340 is exposed from the second end 322 of the spindle 320 and penetrates into the second through-hole 213a of the second extension portion 213. By allowing the first end 321 of the spindle 320 to pass through and engage with the first through-hole 212a of the first extension portion 212, and allowing the positioning member 340 to pass through the second through-hole 213a of the second extension portion 213, the rotation centers of the first bracket 210 and the second bracket 250 sleeved on the outside of the spindle 320 can be aligned with each other, and relative displacement of the two in the radial direction of the spindle 320 can be prevented.

[0082] Furthermore, by passing the external threaded portion 332 of the fixing member 330 through the first through-hole 212a and being locked to the internal threaded portion 323a of the screw hole 323, and by placing the head 331 of the fixing member 330 against the side of the first extension 212 away from the spindle 320, the first end 321 of the spindle 320 is prevented from separating from the first through-hole 212a. In other words, relative displacement of the spindle 320 and the first bracket 210 in the axial direction is prevented.

[0083] like Figure 5As shown, the internal threaded portion 323a of the screw hole 323 is distal to the first end 321 and adjacent to the second end 322. Therefore, the first end 321 of the spindle 320 can be supported by the first through-hole 212a of the first extension 212, while the second end 322 of the spindle 320 can be supported by the external threaded portion 332 of the fixing member 330. This ensures that the spindle 320 is evenly stressed when the hinge assembly 300 is operated, preventing stress concentration on the first end 321 of the spindle 320 and thereby increasing the service life of the spindle 320.

[0084] When assembling the hinge assembly 300, the following steps may be performed: (1) placing the combination of the spindle 320 and the second bracket 250 between the first extension portion 212 and the second extension portion 213 of the first bracket 210, and making the first end 321 and the second end 322 of the spindle 320 face the first through-hole 212a of the first extension portion 212 and the second through-hole 213a of the second extension portion 213, respectively; (2) moving the spindle 320 toward the first extension portion 212 so that the first end 321 of the spindle 320 passes through the first through-hole 212a of the first extension portion 212; and (3) passing the fixing member 330 through the first through-hole 212a of the first extension portion 212 and locking it to the screw hole 323 connected to the first end 321 of the spindle 320, while making the positioning member 340 pass through the second end 322 of the spindle 320 and pass through the second through-hole 213a of the second extension portion 213.

[0085] From the above description, it can be seen that compared with the existing assembly method of the covering hinge, the hinge assembly 300 of this embodiment also only needs to use one fixing member 330 for assembly, so the appearance is relatively simple and is particularly suitable for application in electronic devices 100 where visible screws or rivets are not desired.

[0086] Please refer to Figure 6 as well as Figure 7 . Figure 6 FIG1 is a partial perspective exploded view of a hinge assembly 400 according to another embodiment of the present disclosure. Figure 7 To illustrate Figure 6 A cross-sectional view of the hinge assembly 400 after assembly. Figure 6 and Figure 7 As shown, the hinge assembly 400 includes a first bracket 210, a spindle 420, a fixing member 430, a positioning member 240 and a second bracket 250, wherein the first bracket 210, the positioning member 240 and the second bracket 250 are the same as Figure 2A The embodiment shown in FIG. 1 is a schematic diagram of a hinge assembly 400 of FIG. 1 , and the hinge assembly 400 of FIG. 1 is a schematic diagram of a hinge assembly 400 of FIG. 1 . Figure 2A1 and 2. The differences between the embodiments shown in FIG. 2 are described. Specifically, in this embodiment, the spindle 420 does not have a screw hole 223 connected to the first end 421, and the fixing member 430 is changed to a non-screw type. The fixing member 430 is located on the side of the first extension portion 212 away from the spindle 420. The spindle 420 and the fixing member 430 are configured to be magnetically attracted to each other. For example, the spindle 420 includes a ferromagnetic material, and the fixing member 430 is a magnet. Thereby, the fixing member 430 can use magnetic force to attract the spindle 420, so that the first end 421 of the spindle 420 remains inserted into the first through-hole 212a of the first extension portion 212.

[0087] By inserting the first end 421 of the spindle 420 into and engaging with the first through-hole 212a of the first extension 212, and inserting the positioning member 240 into the second through-hole 213a of the second extension 213, the rotational centers of the first bracket 210 and the second bracket 250, which is sleeved onto the spindle 420, are aligned, preventing relative displacement of the two in the radial direction of the spindle 420. Furthermore, by utilizing the magnetic force of the fixing member 430 to attract the spindle 220, the first end 421 of the spindle 420 is prevented from separating from the first through-hole 212a. In other words, relative displacement of the spindle 420 and the first bracket 210 in the axial direction is prevented.

[0088] like Figure 7 As shown, the fixing member 430 abuts the side of the first extension 212 away from the spindle 420 and partially penetrates the first through-hole 212a of the first extension 212. As can be seen, the first end 421 of the spindle 420 penetrates the first through-hole 212a, and the fixing member 430 also penetrates the first through-hole 212a. This facilitates positioning the fixing member 430 at a fixed position on the first extension 212.

[0089] When assembling the hinge assembly 400, the following steps may be performed: (1) placing the assembly of the spindle 420 and the second bracket 250 between the first extension 212 and the second extension 213 of the first bracket 210, and making the first end 421 and the second end 422 of the spindle 420 face the first through-hole 212a of the first extension 212 and the second through-hole 213a of the second extension 213, respectively; (2) moving the spindle 420 toward the first extension 212 so that the first end 421 and the second end 422 of the spindle 420 face the first through-hole 212a of the first extension 212 and the second through-hole 213a of the second extension 213, respectively; 1 is inserted into the first through-hole 212a of the first extension portion 212; (3) the positioning member 240 is passed through the second through-hole 213a of the second extension portion 213 and connected to the positioning hole 422a at the second end 422 of the spindle 420; and (4) the fixing member 430 is abutted against the side of the first extension portion 212 away from the spindle 420, with the first extension portion 212 located between the spindle 420 and the fixing member 430, so that the fixing member 430 is attracted to the first end 421 of the spindle 420 through the first extension portion 212.

[0090] From the above description, it can be seen that compared with the existing assembly method of the covering hinge, the hinge assembly 400 of this embodiment also only needs to use one fixing member 430 for assembly, so the appearance is relatively simple and is particularly suitable for application in electronic devices 100 where visible screws or rivets are not desired.

[0091] Please refer to Figure 8 as well as Figure 9 . Figure 8 FIG1 is a partial perspective exploded view of a hinge assembly 500 according to another embodiment of the present disclosure. Figure 9 To illustrate Figure 8 A cross-sectional view of the hinge assembly 500 after assembly. Figure 8 and Figure 9 As shown, the hinge assembly 500 includes a first bracket 210, a spindle 520, a fixing member 530, a positioning member 240 and a second bracket 250, wherein the first bracket 210, the positioning member 240 and the second bracket 250 are the same as Figure 2A The embodiment shown in FIG. 1 is a schematic diagram of a hinge assembly 500 of FIG. 1 , and the hinge assembly 500 of FIG. 1 is a schematic diagram of a hinge assembly 500 of FIG. 1 . Figure 2A The differences between the embodiments shown are described below. Specifically, in this embodiment, the fixing member 530 includes a head 531 and a hook 532 connected to each other. The spindle 520 further has a slot 523 connected to the first end 521. The hook 532 passes through the first through-hole 212a of the first extension portion 212 and snaps into the slot 523.

[0092] Specifically, if Figure 9 As shown, the slot 523 includes a first slot section 523a and a second slot section 523b. The first slot section 523a connects the first end 521 and the second slot section 523b. The second slot section 523b expands outward relative to the first slot section 523a to form a stepped portion 523c. The hook 532 passes through the first slot section 523a from the first end 521 and engages with the stepped portion 523c. Furthermore, to facilitate the hook 532's passage through the first slot section 523a, the fixing member 530 may be made of, for example, plastic. This allows the hook 532 to elastically deform while passing through the first slot section 523a and then elastically recover and engage with the stepped portion 523c after passing through the first slot section 523a.

[0093] In addition, the second end 522 of the spindle 520 has a positioning hole 522a. The positioning member 240 further penetrates and engages with the positioning hole 522a. Figure 9As shown, the positioning hole 522a is connected to the second groove section 523b of the retaining groove 523. The positioning hole 522a is expanded outward relative to the second groove section 523b to form a stepped portion 522b. The positioning member 240 abuts the stepped portion 522b. It should be noted that the connection between the positioning hole 522a and the second groove section 523b of the retaining groove 523 is designed to facilitate the formation of the retaining groove 523 in the mandrel 520.

[0094] For example, when manufacturing the mandrel 520, a machining tool with a larger outer diameter (e.g., a milling cutter) may first be used to machine the positioning hole 522a from the second end 522 of the mandrel 520. A machining tool with a medium outer diameter may then be used to machine the second groove section 523b of the retaining groove 523 from the bottom of the positioning hole 522a. Finally, a machining tool with a smaller outer diameter may be used to machine the first groove section 523a of the retaining groove 523 from the second groove section 523b. Alternatively, a machining tool with a smaller outer diameter may first be used to penetrate from the second end 522 of the mandrel 520 to the first end 521. A machining tool with a medium outer diameter may then be used to machine from the second end 522 of the mandrel 520 toward the first end 521 to form the first groove section 523a and the second groove section 523b of the retaining groove 523. Finally, a machining tool with a larger outer diameter may be used to machine from the second end 522 of the mandrel 520 toward the first end 521 to form the positioning hole 522a.

[0095] By inserting the first end 521 of the spindle 520 into and engaging with the first through-hole 212a of the first extension 212, and inserting the positioning member 240 into the second through-hole 213a of the second extension 213, the rotational centers of the first bracket 210 and the second bracket 250, which is sleeved onto the outside of the spindle 520, are aligned, preventing relative displacement of the two in the radial direction of the spindle 520. Furthermore, by inserting the hook 532 of the fixing member 530 into the first through-hole 212a and engaging with the groove 523 of the spindle 520, and placing the head 531 of the fixing member 530 against the side of the first extension 212 away from the spindle 520, the first end 521 of the spindle 520 is prevented from separating from the first through-hole 212a. In other words, relative displacement of the spindle 520 and the first bracket 210 in the axial direction is prevented.

[0096] When assembling the hinge assembly 500, the following steps may be performed: (1) placing the combination of the spindle 520 and the second bracket 250 between the first extension portion 212 and the second extension portion 213 of the first bracket 210, and making the first end 521 and the second end 522 of the spindle 520 face the first through-hole 212a of the first extension portion 212 and the second through-hole 213a of the second extension portion 213, respectively; (2) moving the spindle 520 toward the first extension portion 212 so that the first end 521 of the spindle 520 passes through the first through-hole 212a of the first extension portion 212; (3) passing the positioning member 240 through the second through-hole 213a of the second extension portion 213 and connecting it to the positioning hole 522a at the second end 522 of the spindle 520; and (4) passing the fixing member 530 through the first through-hole 212a of the first extension portion 212 and snapping it into the slot 523 connected to the first end 521 of the spindle 520.

[0097] From the above description, it can be seen that compared with the existing assembly method of the covering hinge, the hinge assembly 500 of this embodiment also only needs to use one fixing member 530 for assembly, so the appearance is relatively simple and is particularly suitable for application in electronic devices 100 where visible screws or rivets are not desired.

[0098] Please refer to Figure 10 as well as Figure 11 . Figure 10 FIG1 is a partial perspective exploded view of a hinge assembly 600 according to another embodiment of the present disclosure. Figure 11 To illustrate Figure 10 A cross-sectional view of the hinge assembly 600 after assembly. Figure 10 and Figure 11 As shown, the hinge assembly 600 includes a first bracket 210, a spindle 620, a fixing member 630, a positioning member 240 and a second bracket 250, wherein the first bracket 210, the positioning member 240 and the second bracket 250 are the same as Figure 2A The embodiment shown in FIG. 1 is a schematic diagram of a hinge assembly 600 of FIG. 1 , and the hinge assembly 600 of FIG. 1 is a schematic diagram of a hinge assembly 600 of FIG. 1 . Figure 2A The differences between the embodiments shown in FIG. 1 and FIG. 2 are described below. Specifically, in this embodiment, the spindle 620 does not have a screw hole 223 connected to the first end 621, and the fixing member 630 is a non-screw type. The fixing member 630 abuts between the second extension 213 and the second end 622 of the spindle 620, thereby maintaining the first end 621 of the spindle 620 inserted into the first through-hole 212a of the first extension 212.

[0099] In some embodiments, as Figure 10 and Figure 11As shown, the positioning member 240 further passes through the fixing member 630. In other words, the fixing member 630 is sleeved outside the positioning member 240. In this way, the positioning member 240 can not only position the second end 622 of the spindle 620, but also further position the fixing member 630 between the second extension portion 213 and the second end 622 of the spindle 620.

[0100] In some embodiments, the fixing member 630 includes a compressible material such as rubber, sponge, or silicone. Thus, when the hinge assembly 600 moves, the second bracket 250 rubs against the spindle 620. The compressible elastic material of the fixing member 630 can provide a buffering and shock-absorbing effect between the second extension 213 and the second end 622. Furthermore, the fixing member 630 can be compressed between the second extension 213 and the second end 622 of the spindle 620, thereby causing the first end 621 of the spindle 620 to more tightly abut the first extension 212 and increasing the difficulty of separating the first end 621 of the spindle 620 from the first through-hole 212a. In other words, this prevents the first end 621 of the spindle 620 from separating from the first through-hole 212a.

[0101] By inserting the first end 621 of the spindle 620 into and engaging with the first through-hole 212a of the first extension 212, and inserting the positioning member 240 into the second through-hole 213a of the second extension 213, the rotational centers of the first bracket 210 and the second bracket 250, which is sleeved onto the outside of the spindle 620, are aligned, preventing relative displacement in the radial direction of the spindle 620. Furthermore, by abutting the fixing member 630 between the second extension 213 and the second end 622 of the spindle 620, the first end 621 of the spindle 620 is prevented from separating from the first through-hole 212a. In other words, relative displacement in the axial direction between the spindle 620 and the first bracket 210 is prevented.

[0102] When assembling the hinge assembly 600, the following steps may be performed: (1) placing the combination of the spindle 620 and the second bracket 250 between the first extension portion 212 and the second extension portion 213 of the first bracket 210, and making the first end 621 and the second end 622 of the spindle 620 face the first through-hole 212a of the first extension portion 212 and the second through-hole 213a of the second extension portion 213, respectively; (2) moving the spindle 620 toward the first extension portion 212 so that the first end 621 of the spindle 620 passes through the first through-hole 212a of the first extension portion 212; (3) placing the fixing member 630 and abutting it between the second extension portion 213 and the second end 622 of the spindle 620; and (4) passing the positioning member 240 through the second through-hole 213a of the second extension portion 213 and the fixing member 630 in sequence and connecting them to the positioning hole 622a located at the second end 622 of the spindle 620.

[0103] From the above description, it can be seen that compared with the existing assembly method of the covering hinge, the hinge assembly 600 of this embodiment also only needs to use one fixing member 630 for assembly, so the appearance is relatively simple and is particularly suitable for application in electronic devices 100 where visible screws or rivets are not desired.

[0104] From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that in the hinge assembly of the present invention, the first end of the spindle is engaged with the first through-hole of the first extension portion of the first bracket, thereby limiting the rotation of the spindle relative to the first bracket. In addition, the positioning member connected to the second end of the spindle is inserted into the second through-hole of the second extension portion of the first bracket. In this way, the rotation centers of the first bracket and the second bracket sleeved on the outside of the spindle can be aligned with each other, and the relative displacement of the two in the radial direction of the spindle can be prevented. In addition, the hinge assembly also uses a fixing member to prevent the relative displacement of the spindle and the first bracket in the axial direction. Compared with the existing assembly method of the covering hinge, the hinge assembly of the present invention only needs to use one fixing member for assembly, so the appearance is relatively simple, and it is particularly suitable for use in electronic devices where it is not desired to have visible screws or rivets.

[0105] Although the present invention has been disclosed in the form of embodiments as described above, they are not intended to limit the present invention. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the appended claims.
