If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0066] Figure 1 A schematic diagram of the structure of a VR wearable device in one embodiment of the related technology is shown; Figure 2 A schematic diagram of a VR wearable device in use is shown in one embodiment of the related technology; for ease of explanation, only the content related to the embodiment of the related technology is shown.

[0067] Please refer to Figure 1 One embodiment of the related technology provides a VR wearable device, which includes a housing 10, a wraparound strap 20 disposed on the housing 10, and related components (such as lenses 30, displays 40, etc.) disposed within the housing 20. (Refer to reference...) Figure 2 By wearing the wraparound strap 20 on the user's head, one side of the shell 10 can be placed against the user's face.

[0068] The inventors of this application have noticed that, due to the different facial structures of different users (e.g., some users have high cheekbones, some users have low cheekbones) and the different external environments of different users' faces (e.g., some users need to wear glasses), the outer shell 10 cannot fit the user's face well.

[0069] The inventors of this application attempted to provide a soft material on the side of the outer shell 10 that abuts against the user's face, or to make the wrap-around strap 20 adjustable. However, they still found that the outer shell 10 could not fit the user's face well, and the force applied to different parts of the face was also different, which affected the user's wearing comfort.

[0070] Based on this, embodiments of this application provide a housing assembly for wearable devices, which adapts to the faces of different users by improving the structure of the housing assembly. The housing assembly will be described below with reference to the accompanying drawings and some embodiments.

[0071] Figure 3 A schematic diagram of the structure of the housing assembly 100 in one embodiment of this application is shown; Figure 4 It shows Figure 3 A schematic diagram of a partial cross-sectional view of the side of the housing assembly 100; for ease of explanation, only the content relevant to the embodiments of this application is shown.

[0072] In some embodiments, please refer to Figure 3 and Figure 4 This application provides a housing assembly 100, which includes a front housing 110, a first housing 120, a second housing 130, and an adjustment mechanism 140.

[0073] The front housing 110 is relative to the user. That is, the front housing 110 is located in front of the user's face.

[0074] The first housing 120 and the second housing 130 are respectively connected to the same side of the front housing 110. That is, the first housing 120 and the second housing 130 are respectively connected to the side of the front housing 110 facing the user. The first housing 120 and the second housing 130 are independent housings, and the first housing 120 and the second housing 130 are arranged opposite each other along a first direction F1, which can be the up-down direction shown in the figure. That is, one of the first housing 120 and the second housing 130 is located above, and the other is located below. Figure 3 and Figure 4 For example, the first housing 120 is located on top and the second housing 130 is located below.

[0075] The front housing 110, the first housing 120, and the second housing 130 enclose a receiving cavity R. The receiving cavity R is used to accommodate relevant components of the wearable device (such as the lenses, display, etc. mentioned above). It can be understood that... Figure 3 For example, the first housing 120 and the second housing 130 can be roughly C-shaped. When the second housing 130 is located below, the second housing 130 is also provided with a corresponding recess. The recess can fit into the area near the nose on the user's face so that the user can wear it.

[0076] One of the first housing 120 and the second housing 130 is rotatably connected to the front housing 110 about a first axis C1, where the first axis C1 is perpendicular to a first direction F1. That is, the first housing 120 can be fixedly connected to the front housing 110, and the second housing 130 can be rotatably connected to the front housing 110; alternatively, the first housing 120 can be rotatably connected to the front housing 110, and the second housing 130 can be fixedly connected to the front housing 110. Figure 3 and Figure 4 For example, this illustrates a scenario where the first housing 120 is fixedly connected to the front housing 110, and the second housing 130 is rotatably connected to the front housing 110. It can be understood that in... Figure 3 and Figure 4 In the schematic illustration, the second housing 130 is rotatably connected to the front housing 110 around the first axis C1, allowing for pitch adjustment of the second housing 130. This pitch adjustment process enables the side of the first housing 120 and the second housing 130 facing the user's face to better fit the user's facial structure, thus adapting to different users' faces. Furthermore, since the relative movement between the first housing 120 and the second housing 130 is a pitch movement, it can mitigate the problem of the wearable device tilting upwards or downwards, or uneven pressure on the head.

[0077] An adjustment mechanism 140 is fitted between the first housing 120 and the second housing 130. One of the first housing 120 and the second housing 130 is defined as the target housing. The adjustment mechanism 140 is configured to allow the target housing to rotate relative to the front housing 110, thereby adjusting the distance d between the first housing 120 and the second housing 130 in the first direction F1. Figure 3 and Figure 4 For example, the adjustment mechanism 140 can rotate the second housing 130 relative to the front housing 110 in response to the user's operation, thereby adjusting the distance d between the first housing 120 and the second housing 130 in the first direction F1, thereby adjusting the pitch between the first housing 120 and the second housing 130.

[0078] It is understandable that when a user has high cheekbones or a high nose bridge, the outer shell assembly 100 will rise or forcefully compress the face. Conversely, when a user has low cheekbones or a low nose bridge, or a high forehead, the outer shell assembly 100 will sink or forcefully compress the forehead. By adjusting the pitch between the first shell 120 and the second shell 130, the relative longitudinal position of the first shell 120 and the second shell 130 with respect to the user's face can be changed, thus improving the uneven force distribution.

[0079] Therefore, by dividing the housing connected to the front housing 110 into two parts (i.e., the first housing 120 and the second housing 130) and rotatably connecting the target housing (i.e., one of the first housing 120 and the second housing 130) to the front housing 110, and using the adjustment mechanism 140, the target housing can rotate relative to the front housing 110 under the adjustment of the adjustment mechanism 140, thereby adjusting the distance d between the first housing 120 and the second housing 130. This allows for the use of different distances d according to different user face shapes, improving the stability and comfort of the user when wearing the wearable device.

[0080] In some embodiments, please continue to refer to Figure 3 and Figure 4 The adjustment mechanism 140 includes a mating member 141, a guide member 142, and a rotating member 143. The mating member 141 is movably disposed along a second direction F2 on the edge of the first housing 120 facing the second housing 130. The second direction F2 can be generally considered as a front-rear direction. The guide member 142 is disposed on the edge of the second housing 130 facing the first housing 120. The rotating member 143 is mated between the mating member 141 and the guide member 142. The rotating member 143 is configured to drive the mating member 141 to move along the second direction F2 during rotation, and to reciprocate along the second direction F2 under the guidance of the mating member 141 and the guide member 142, so that the target housing rotates relative to the front housing 110 to adjust the distance d. The rotation axis C2 of the rotating member 143, the second direction F2, and the first direction F1 are perpendicular to each other, and the second direction F2 intersects the first axis C1.

[0081] It is understandable that when the rotating member 143 rotates, the mating member 141 can move under the drive of the rotating member 143. Since the mating member 141 is movable relative to the first housing 120 along the second direction F2, the mating member 141 can also restrict the rotation of the rotating member 143 in the second direction F2, and can cooperate with the guide member 142 to make the rotating member 143 reciprocate along the second direction F2 during rotation. When the rotating member 143 reciprocates along the second direction F2, it occurs simultaneously with the rotation of the rotating member 143, and the dimension of the rotating member 143 in the first direction F1 will also change with the rotation. When the dimension of the rotating member 143 changes in the first direction F1, the target housing will rotate relative to the front housing 110, thereby adjusting the distance d between the first housing 120 and the second housing 130 in the first direction F1. Figure 4 For example, the target housing is the second housing 130. The second housing 130 can rotate relative to the front housing 110 under the action of the rotating member 143, thereby realizing the distance d between the first housing 120 and the second housing 130 in the first direction F1.

[0082] It should be noted that the first axis C1 and the rotation axis C2 can be parallel to each other, that is, the first axis C1 and the second direction F2 can be perpendicular to each other. This can be configured according to specific usage, and the embodiments of this application do not impose specific limitations on this.

[0083] Therefore, by setting the mating part 141, the guide part 142 and the rotating part 143, the three parts can cooperate with each other to adjust the distance d between the first housing 120 and the second housing 130.

[0084] Figure 5 It shows Figure 3 The schematic diagram shows the structure of the rotating member 143 in the housing assembly 100; for ease of explanation, only the content related to the embodiments of this application is shown.

[0085] In some embodiments, please continue to refer to Figure 4 and in conjunction with reference Figure 5 The rotating member 143 includes a rotating part 143a, a plurality of teeth 143b, and a protrusion 143c. The rotating part 143a is capable of rotating about the rotation axis C2 in response to an external force.

[0086] Multiple teeth 143b are sequentially arranged along the circumference of the rotating part 143a on a portion of its periphery, and these teeth 143b mesh with the mating member 141. That is, the mating member 141 also has teeth corresponding to the multiple teeth 143b. The mating member 141 can be constructed as a rack structure, and the multiple teeth 143b are arranged on a portion of the periphery of the rotating part 143a, so that the rotating part 143a and the multiple teeth 143b form a part of a gear-like structure.

[0087] A protrusion 143c protrudes from another part of the periphery of the rotating part 143a, and the protrusion 143c cooperates with the guide member 142. The protrusion 143c is configured such that, as the rotating member 143 moves along the second direction F2 and away from the front housing 110, the size of the protrusion 143c along the first direction F1 tends to increase or decrease, so as to adjust the distance d by rotating the target housing relative to the front housing 110. That is, by controlling the size of the protrusion 143c, the target housing is rotated relative to the front housing 110 to adjust the distance d. In other words, the distance d between the first housing 120 and the second housing 130 in the first direction F1 can be adjusted by the size of the protrusion 143c in the first direction F1.

[0088] Thus, by setting the teeth 143b and the protrusions 143c, not only can the distance d between the first housing 120 and the second housing 130 in the first direction F1 be adjusted, but also, since the multiple teeth 143b mesh with the mating parts 141, stepless adjustment can be achieved according to the usage requirements, which is more beneficial to the user.

[0089] It is understandable that, taking the increasing trend as an example, "increasing trend" can include phased increases, such as increasing first, then remaining unchanged, and then increasing again; it can also include continuous increases, such as a consistent rate of increase or an initial rapid increase followed by a slower increase. For example, as the rotating member 143 moves along the second direction F2 and away from the front housing 110, the dimension of the protrusion 143c along the first direction F1 becomes larger as it moves further away from the front housing 110. Another example is that as the rotating member 143 moves along the second direction F2 and away from the front housing 110, the dimension of the rotating member 143 along the first direction F1 gradually increases. The choice can be made according to the specific application, and this application embodiment does not impose specific limitations on this. The understanding of the decreasing trend can be referred to in relation to the increasing trend, and will not be elaborated further here. Figure 4 and Figure 5 For example, the protrusion 143c is constructed such that, as the rotating member 143 moves along the second direction F2 and away from the front housing 110, the size of the protrusion 143c along the first direction F1 tends to increase.

[0090] In some embodiments, please continue to refer to Figures 3 to 5 The protrusion 143c has an abutment surface m that can abut against the guide 142. At least a portion of the orthographic projection of the abutment surface m onto the reference plane is a preset shape, which is a partial elliptical outline, and the reference plane is perpendicular to the rotation axis C2. It can be understood that when the preset shape is a partial elliptical outline, the distance of this part from the rotation axis C2 is variable, thereby enabling adjustment of the distance d between the first housing 120 and the second housing 130 in the first direction F1. For example, with Figure 5 For example, the orthographic projection of the abutment surface m of the protrusion 143c onto the reference surface is illustrated as a preset shape, which is a partial elliptical outline. That is, the orthographic projection of the abutment surface m of the protrusion 143c onto the reference surface entirely constitutes a partial elliptical outline. Of course, in other embodiments, the orthographic projection of the abutment surface m onto the reference surface can be a curve other than an elliptical part, as long as the required adjustment process can be achieved. This application does not impose specific limitations on this.

[0091] Thus, by constructing the contact surface m of the protrusion 143c as an approximately elliptical portion, it is more conducive to the adjustment process.

[0092] In some embodiments, please continue to refer to Figure 4 and Figure 5The mating part 141 has a dimension of L1 along the second direction F2, the edge of the first housing 120 facing the second housing 130 has a dimension of L2 along the second direction F2, and the protrusion 143c has an abutment surface m that abuts against the guide 142. The length of the abutment surface m along the circumferential direction of the protrusion 143c is L3. Wherein, L1 and L3 are both less than L2, and the difference between L2 and L3 is greater than L1.

[0093] Thus, through the coordinated cooperation of various dimensions, it is beneficial to design the adjustment range according to the usage requirements, as well as the range of the distance d between the first housing 120 and the second housing 130 in the first direction F1.

[0094] It is understood that, in order to adjust the distance d between the first housing 120 and the second housing 130 in the first direction F1 via the protrusion 143c, the dimension of the protrusion 143c in the first direction F1 is approximately greater than the distance between the teeth 143b and the rotation axis C2. That is, when the rotating member 143 and the plurality of teeth 143b are considered as part of a gear, and the protrusion 143c is considered as part of a cam, the radius of the gear is smaller than the radius of the cam.

[0095] In some embodiments, please continue to refer to Figure 4 The first housing 120 has a first guide groove g1 on its edge facing the second housing 130. The first guide groove g1 extends along the second direction F2, and the mating part 141 is movably disposed within the first guide groove g1 along the second direction F2. In other embodiments, please refer to... Figure 4 The first housing 120 has a second guide groove g2 on one edge facing the second housing 130, the first guide groove g1 extends along the second direction F2, and the guide member 142 is disposed in the second guide groove g2.

[0096] Thus, the required guiding function can be achieved by constructing the first guide groove g1 and / or the second guide groove g2. In addition, since the mating part 141 is correspondingly disposed in the first guide groove g1 and the guide part 142 is correspondingly disposed in the second guide groove g2, the mating part 141 and the guide part 142 can be covered, which can also improve the overall aesthetics of the device.

[0097] In some embodiments, please continue to refer to Figure 3 The adjusting mechanism 140 also includes an operating element 144, which is located on the side of the rotating element 143 opposite to the receiving cavity R. It is understood that... Figure 4 For ease of illustration, the rotating element 143 is shown, but the operating element 144 is not shown. For example, the operating element 144 may be in the form of a knob.

[0098] Thus, by setting up the operating component 144, it is convenient for the user to rotate the rotating component 143 using the operating component 144.

[0099] In some embodiments, the adjustment mechanism 140 further includes a locking member (not shown in the figure). The locking member can pass through one of the first housing 120 and the second housing 130, as well as the rotating member 143. That is, the locking member can further fix the rotating member 143. For example, a plurality of corresponding locking holes (not shown in the figure) can be provided on the first housing 120 and / or the second housing 130, and on the rotating member 143. These locking holes can be used to characterize the angle of rotation of different target housings relative to the front housing 110. In this way, it is convenient for the user to adjust the distance d between the first housing 120 and the second housing 130 in the first direction F1 according to the different locking holes.

[0100] In some embodiments, please continue to refer to Figure 4 The housing assembly 100 also includes an elastic element 150. The elastic element 150 is connected between the first housing 120 and the second housing 130, and provides a spring force that tends to bring the first housing 120 and the second housing 130 closer together. For example, the elastic element 150 can be a spring. This improves the stability between the first housing 120 and the second housing 130. It is understood that in the case where the plurality of teeth 143b engage with the mating portion as illustrated in some of the foregoing embodiments, it also improves the stability of the engagement between the plurality of teeth 143b and the mating portion. Of course, the target housing can also be rotatably connected to the front housing 110 via a pre-tensioned shaft; that is, a member with a preset elastic force can be correspondingly provided at the shaft. The configuration can be tailored to specific usage conditions, and this application embodiment does not impose specific limitations on this.

[0101] In some embodiments, please continue to refer to Figure 3 The wearable device also includes a cushioning element 160. The cushioning element 160 is located on the side of the first housing 120 and / or the second housing 130 opposite to the front housing 110. The cushioning element 160 may be a soft component such as sponge or silicone. Figure 3 The diagram illustrates the arrangement of the cushioning element 160 on the side of the second housing 130 facing away from the front housing 110. This improves user comfort when the first housing 120 and / or the second housing 130 are in contact with the user's face.

[0102] Based on the same inventive concept, this application also provides a wearable device, including the outer shell assembly 100 of any of the above embodiments. The wearable device also possesses the advantages of the outer shell assembly 100 of any of the above embodiments, and will not be repeated here.

[0103] In summary, this embodiment divides the housing connected to the front housing 110 into two parts (i.e., the first housing 120 and the second housing 130), and rotatably connects the target housing (i.e., one of the first housing 120 and the second housing 130) to the front housing 110. Combined with the adjustment mechanism 140, the target housing can rotate relative to the front housing 110 under the adjustment of the adjustment mechanism 140, thereby adjusting the distance d between the first housing 120 and the second housing 130. This allows for different distances d to be used according to different user face shapes, improving the stability and comfort of the user when wearing the device. By setting the adjustment mechanism 140 in the form of a mating part 141, a guide part 142, and a rotating part 143, and using the first guide groove g1 to accommodate the mating part 141, the second guide groove g2 to accommodate the guide part 142, and the distance d between the first housing 120 and the second housing 130 to accommodate the rotating part 143, space can be effectively utilized and saved, and the structure is simple and easy to adjust.

[0104] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0105] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
