To make the figure simple, the shell 140 is not shown in Figure 4. In this embodiment, as shown in Figures 4 to 6, the connecting portion 110 includes a main body 111 and a first buckle portion 112. In fact, the number of the first buckle portions 112 is two, and they are respectively located at the two ends of the main body 111, while Figures 4 to 6 only show one end of the main body 111. Furthermore, as shown in Figures 4 to 6, the first buckle portion 112 includes a column 1121, a buckle 1122 and a limiter 1123. The column 1121 is substantially a cylinder and has a first center line C1, which overlaps with the second axis X2 of FIG. 1, and the column 1121 is connected to one of the two opposite ends of the main body 111, and the stopper 1123 is disposed at one end of the column 1121 away from the main body 111 and away from the first center line C1. The buckle 1122 is connected to the column 1121 and is located between the main body 111 and the stopper 1123.

[0035] In addition, as shown in FIG. 4 , the bracket 120 includes a connected arc frame 121 and a second buckle portion 122, the arc frame 121 includes a frame body 1211 and two pivot portions 1212, and the second buckle portion 122 of the bracket 120 is disposed on the frame body 1211.

[0036] Further, as shown in FIGS. 4 to 6 , the first center line C1 of the column 1121 extends along the first direction D1, that is, the second axis X2 also extends along the first direction D1, and the first axis X1 extends along the second direction D2. In this embodiment, the first direction D1 and the second direction D2 intersect with each other, that is, the first axis X1 and the second axis X2 are not parallel to each other.

[0037] Please refer to Figures 7 and 8. Figure 7 is a front view of the bracket 120 of Figure 4 facing the abutting surface SA. Figure 8 is a cross-sectional view along the line segment AA of Figure 7, wherein the first buckle portion 112 and the second buckle portion 122 are engaged with each other. In this embodiment, as shown in Figures 7 to 8, the second buckle portion 122 has an abutment surface SA, an opening OP, a notch N, a first hole H1 and an annular groove GA, the abutment surface SA is suitable for abutting the main body 111 of the connecting portion 110, the opening OP and the notch N are located on the abutment surface SA, and the opening OP, the notch N, the first hole H1 and the annular groove GA are connected to each other, the opening OP is aligned with the first hole H1 and is at least partially circular, and the opening OP is configured to allow the column 1121 and the limit member 1123 of the first buckle portion 112 to pass through, the first hole H1 is substantially circularly configured to accommodate the column 1121 and the limit member 1123, the notch N is configured to allow the buckle 1122 to pass through, and the annular groove GA is configured to accommodate the buckle 1122 to limit the second buckle portion 122 from detaching from the first buckle portion 112.

[0038] More specifically, after the fastener 1122 of the first fastener portion 112 passes through the notch N of the second fastener portion 122 and enters the annular groove GA, the bracket 120 can rotate relative to the connecting portion 110 around the second axis X2 so that the position of the notch N and the fastener 1122 are staggered with each other, so that the fastener 1122 cannot move only along the first direction D1 and leave the annular groove GA, thereby effectively preventing the second fastener portion 122 from being separated from the first fastener portion 112. For example, as shown in FIG. 8, the notch N of the second fastener portion 122 is located at the upper side in the figure, and the fastener 1122 accommodated in the annular groove GA is located at the lower side in the figure, so that the first fastener portion 112 and the second fastener portion 122 can be securely engaged with each other.

[0039] Furthermore, as shown in Figure 8, the second buckle portion 122 has an inner surface SI, which is connected to the abutting surface SA and surrounds and defines the above-mentioned first hole H1, and the column 1121 of the first buckle portion 112 at least partially abuts the inner surface SI of the second buckle portion 122, thereby helping to maintain the relative positions of the first buckle portion 112 and the second buckle portion 122.

[0040] Please refer to Figures 4 and 9. Figure 9 is a cross-sectional view along line segment BB of Figure 8. In the present embodiment, as shown in Figures 4 and 9, the frame body 1211 of the arc frame 121 has an outer surface SO and a second hole H2, and the second hole H2 is located on the outer surface SO and connected to the first hole H1. Furthermore, the head-mounted device 100 further includes a limit pin 130, as shown in Figure 9, the limit pin 130 is configured to be inserted into the second hole H2 to interfere with the limit member 1123 of the first buckle portion 112 to limit the rotation range of the limit member 1123 in the first hole H1, that is, to limit the rotation range of the bracket 120 relative to the connecting portion 110 around the second axis X2.

[0041] More specifically, as shown in FIG. 9 , the limiting pin 130 has a second center line C2, a vertical distance V is formed between the first center line C1 of the column 1121 and the second center line C2 of the limiting pin 130, and the column 1121 has a radius R. In this embodiment, in order for the limiting pin 130 to have a limiting effect on the limiting member 1123, the vertical distance V is smaller than the radius R of the column 1121.

[0042] Please refer to Figures 4, 9 and 10. Figure 10 is a cross-sectional view along the line segment CC of Figure 9. In the present embodiment, as shown in Figures 4, 9 and 10, the frame body 1211 of the arc frame 121 further has a groove GR, the groove GR is located on the outer surface SO of the frame body 1211 and is connected to the second hole H2, the groove GR has a first diameter M1, the second hole H2 has a second diameter M2, and the first diameter M1 is greater than the second diameter M2. Furthermore, the head-mounted device 100 further includes a stopper glue 150. The stopper glue 150 is disposed in the groove GR and connected to the limit pin 130, and the stopper glue 150 at least partially protrudes from the outer surface SO of the frame body 1211. As described above, the housing 140 is pivotally connected to the arc frame 121 of the bracket 120 around the first axis X1 (see FIGS. 1 to 4 for the first axis X1). When the housing 140 rotates relative to the bracket 120 around the first axis X1, the stopper glue 150 that at least partially protrudes from the outer surface SO can abut the housing 140 to prevent the housing 140 from directly pressing against the arc frame 121, thereby effectively avoiding the chance of the housing 140 and the arc frame 121 being damaged by being squeezed against each other. In practical applications, for example, the stopper glue 150 and the limit pin 130 can be connected by adhesive, but the present invention is not limited thereto.

[0043] It is worth noting that, based on the simple structure of the first buckle portion 112 of the connecting portion 110 and the second buckle portion 122 of the bracket 120, and the simple assembly method between the first buckle portion 112 and the second buckle portion 122 without involving additional tools, the production cost of the head mounted device 100 can be effectively reduced.

[0044] In summary, the technical solution disclosed in the above embodiments of the present invention has at least the following advantages:

[0045] (1) By inserting the limiting pin into the second hole to interfere with the limiting piece of the first buckle portion, the rotation range of the bracket relative to the connecting portion around the second axis can be simply and easily limited.

[0046] (2) When the shell rotates relative to the bracket around the first axis, at least a portion of the stopper rubber protruding from the outer surface of the arc frame can abut the shell to prevent the shell from directly pressing against the arc frame, thereby effectively avoiding the chance of the shell and the arc frame being damaged due to mutual squeezing.

[0047] (3) Based on the simple structure of the first buckle portion of the connecting portion and the second buckle portion of the bracket, and the simple assembly method between the first buckle portion and the second buckle portion without involving additional tools, the production cost of the head mounted device can be effectively reduced.
