[ detailed description ] embodiments

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that the details of the various implementations are not to be taken in a limiting sense. That is, in some embodiments of the invention, details of the various implementations are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner. And features of different embodiments may be applied interactively, if possible.

Fig. 1 is a perspective view of a fixing device 100 according to an embodiment of the invention. In this embodiment, as shown in fig. 1, the fixing device 100 includes a housing 190 and a plurality of connecting bands 130, the connecting bands 130 are respectively connected to the head-mounted apparatus 200 (see fig. 2) in an extending direction E, and the connecting bands 130 are adapted to extend or be received along the extending direction E relative to the housing 190, so that the head-mounted apparatus 200 can be fixed on the head of the user.

Please refer to fig. 2, which is a schematic application diagram of the fixing device 100 of fig. 1. For example, as shown in fig. 2, the head-mounted apparatus 200 may be a face mask, and the connection belt 130 is connected to the head-mounted apparatus 200 in the extending direction E, and the housing 190 is located at the back of the head of the user, i.e. the head of the user is located between the head-mounted apparatus 200 and the housing 190. By extending or receiving the connection band 130 relative to the housing 190 along the extending direction E, the tightness of the head-mounted apparatus 200 on the head of the user can be adjusted, so that the head-mounted apparatus 200 can be comfortably fixed on the head of the user.

Referring to fig. 3, which is a partial perspective view of the fixing device 100 of fig. 1, a rack 131 is engaged with a gear 120. In the present embodiment, as shown in fig. 3, the fixing device 100 includes a base plate 110, a gear 120, and a plurality of connection bands 130. The base plate 110 has pillars 111, and the pillars 111 extend perpendicularly from a surface of the base plate 110. The gear 120 is sleeved on the cylinder 111, and the gear 120 can rotate around the cylinder 111. The connecting belt 130 has a first opening OP1 and a rack 131, respectively, the rack 131 is disposed along the extending direction E of the connecting belt 130 and is located at one side of the first opening OP1, and the rack 131 is disposed to movably engage with the gear 120.

Further, as shown in fig. 3, the connection bands 130 are stacked on each other. Also, the number of the connection bands 130 may be four and arranged in a cross shape according to actual conditions.

In practical applications, when one of the connection belts 130 is pulled out in the extending direction E relative to the base plate 110, as described above, since the rack 131 is movably engaged with the gear 120, the gear 120 rotates around the cylinder 111 along with the pulled-out connection belt 130. However, since the rack 131 of the other connecting belt 130 is movably engaged with the gear 120, when the gear 120 rotates around the column 111, the other connecting belt 130 is extended along the extending direction E relative to the base plate 110 due to the rotation of the gear 120. In other words, as long as any one of the connection bands 130 is pulled out relative to the base plate 110, all the connection bands 130 simultaneously extend out in the respective extending directions E relative to the base plate 110, so that the user can conveniently adjust the tightness of wearing the head-mounted device 200. It should be noted that, as shown in fig. 3, the rack 131 of each connecting strap 130 is correspondingly disposed at one side of each first opening OP1 along the extending direction E, so that the connecting straps 130 can be synchronously extended relative to the bottom plate 110 or synchronously retracted towards the bottom plate 110.

Referring to fig. 4, which is a partial perspective view of the fixing device 100 of fig. 1, a fin 161 of a button 160 and a positioning portion 150 interfere with each other. In the present embodiment, as shown in fig. 4, the fixing device 100 further includes a rotating portion 140, a positioning portion 150, and a button 160. The rotating portion 140 is connected to the gear 120 (the gear 120 is covered by the rotating portion 140, so the gear 120 is not shown in fig. 4, the gear 120 is please see fig. 3), so the rotating portion 140 can rotate along with the gear 120, the gear 120 is located between the rotating portion 140 and the bottom plate 110, the rotating portion 140 has a space S, and the column 111 (the column 111 is covered by the button 160, so the column 111 is not shown in fig. 4, and the column 111 is please see fig. 3) is at least partially located in the space S. The positioning part 150 is connected to the rotating part 140, so that the positioning part 150 can rotate with the rotating part 140, and the positioning part 150 is located in the space S. The button 160 is located at an end of the cylinder 111 away from the base 110, and the button 160 does not rotate relative to the cylinder 111, so that when the gear 120, the rotating portion 140 and the positioning portion 150 rotate around the cylinder 111, the button 160 and the cylinder 111 are all kept stationary. The button 160 has at least one fin 161, and the fin 161 has an inclined surface 162 and a vertical surface 163 opposite to each other (see fig. 5-6 for the inclined surface 162 and the vertical surface 163).

Please refer to fig. 5, which is an interaction diagram of the positioning portion 150 and the fin 161 shown in fig. 4, wherein the positioning portion 150 moves toward the inclined surface 162 of the fin 161. As described above, when one of the connection belts 130 is pulled out in the extending direction E with respect to the base plate 110, the gear 120 rotates with the pulled-out connection belt 130. For example, the gear 120 rotates in the first direction D1 (see fig. 3 at the same time as the first direction D1), and the rotating portion 140 and the positioning portion 150 also rotate around the cylinder 111 in the first direction D1. In the present embodiment, as shown in fig. 5, when the rotating part 140 and the positioning part 150 rotate in the first direction D1, the positioning part 150 slides along the inclined surface 162 to cross the fins 161, so that the gear 120, the rotating part 140, and the positioning part 150 can continue to rotate around the cylinder 111 in the first direction D1, and the connecting band 130 can continue to synchronously extend relative to the bottom plate 110.

Please refer to fig. 6, which is an interaction diagram of the positioning portion 150 and the fin 161 shown in fig. 4, wherein the positioning portion 150 moves toward the vertical surface 163 of the fin 161. On the contrary, when the rotating part 140 and the positioning part 150 rotate in the second direction D2 (the second direction D2 is also shown in fig. 3) opposite to the first direction D1, the positioning part 150 is pressed by the vertical surface 163, and therefore, the gear 120, the rotating part 140 and the positioning part 150 cannot continue to rotate around the cylinder 111 in the second direction D2, and the connecting belt 130 cannot be stored toward the bottom plate 110.

Fig. 7 is a cross-sectional view taken along line X-X of fig. 1. In this embodiment, as shown in fig. 7, the fixing device 100 further includes a second elastic member 180. The second elastic member 180 connects the cylinder 111 and the rotating part 140. When the gear 120, the rotating part 140, and the positioning part 150 rotate about the cylinder 111 in the first direction D1, the second elastic member 180 is elastically compressed and stores elastic potential energy. In other words, as the connecting band 130 is pulled out more relative to the base plate 110, the elastic potential energy stored by the second elastic element 180 due to the elastic compression is relatively higher. In practical applications, the second elastic element 180 is a torsion spring, but the invention is not limited thereto.

Furthermore, as shown in fig. 7, the fixing device 100 further includes a first elastic element 170. The first elastic member 170 connects the button 160 with the cylinder 111 such that the button 160 can be elastically moved relative to the cylinder 111 in a direction in which the cylinder 111 extends. As such, when the positioning portion 150 slides along the inclined surface 162 of the fin 161 as described above, the fin 161 can elastically compress the button 160 toward the column 111, so that the positioning portion 150 can more easily cross over the fin 161.

In addition, when the user presses the button 160, the button 160 moves toward the base plate 110, and the first elastic member 170 stores elastic potential energy by being elastically compressed. By moving the button 160 toward the bottom plate 110, the fins 161 also move toward the bottom plate 110, so the vertical surface 163 of the fins 161 can be offset from the positioning part 150, and the positioning part 150 is no longer pressed by the vertical surface 163. In this way, the second elastic element 180 is elastically compressed and stores elastic potential energy to be released, so that the gear 120, the rotating portion 140 and the positioning portion 150 can rotate around the cylinder 111 along the second direction D2, and the connecting belt 130 can be synchronously accommodated towards the bottom plate 110, and the gear 120, the rotating portion 140 and the positioning portion 150 can also be reset.

In short, when the user presses the button 160, the connection band 130 can be synchronously received toward the bottom plate 110, so that the head-mounted device 200 can be conveniently and rapidly fixed on the head of the user, and the operation process is simple and easy. In addition, when the user no longer presses the button 160, the elastic potential energy stored by the first elastic element 170 due to the elastic compression is also released, so that the button 160 can be reset.

Further, as shown in fig. 7, the housing 190 is connected to the base plate 110, and the housing 190 has a through hole H, and the button 160 at least partially protrudes from the through hole H for the user to press.

In addition, as shown in fig. 1 and 7, the housing 190 further has a plurality of second openings OP2, and the second openings OP2 are used for allowing the corresponding connecting bands 130 to pass through, which helps to maintain the position of the connecting bands 130 relative to the housing 190.

Please refer to fig. 8. Fig. 8 is a schematic application diagram of a fixing device 100 according to another embodiment of the invention. In the present embodiment, as shown in fig. 8, the head-mounted device 200 may be a Virtual Reality (VR) head-mounted display or the like, and in the present embodiment, the number of the connection bands 130 is three and the connection bands are arranged in a T-shape.

In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

(1) as only any one of the connecting bands is pulled out relative to the bottom plate, all the connecting bands can synchronously extend out relative to the bottom plate along the respective extending directions, the tightness of the wearing head-mounted device can be conveniently adjusted by a user.

(2) When a user applies pressure to the button, the connecting band can be synchronously stored towards the bottom plate, so that the head-mounted appliance can be conveniently and quickly fixed on the head of the user, and the operation process is simple and easy.

While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
