[0040] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0042] With the rapid development of VR technology, head-mounted display devices are becoming increasingly popular among users. Currently, head-mounted display devices with multiple camera components require a significant amount of space for the connecting components between the multiple camera components and the main circuit board during assembly, resulting in an excessively large overall size and a poor user experience.

[0043] To address the aforementioned problems, this application provides a head-mounted display device, which can be referred to... Figures 1-3 The head-mounted display device includes a housing 1, a main circuit board 2, a camera assembly 3, and a flexible connector 4. The main circuit board 2, camera assembly 3, and flexible connector 4 are all housed within the housing 1 to achieve VR imaging. Specifically:

[0044] The housing 1 includes a front shell 11, a middle shell 12, and a rear shell (not shown in the figure) connected in sequence. The front shell 11, the middle shell 12, and the rear shell can be fixedly connected by snap-fit ​​connections or by screws or other connecting components. In this embodiment, as shown... Figure 4 As shown, one end of the front shell 11 is rotatably connected to the middle shell 12, and the other end is snapped onto the middle shell 12 by a buckle 111. Preferably, buckles 111 can also be provided on both sides of the front shell 11, so that when the front shell 11 is fastened to the middle shell 12, it is further snapped onto the middle shell 12 by the buckles 111 on both sides.

[0045] In this embodiment, at least two camera components 3 are provided, and both camera components 3 are installed inside the front housing 11. The camera components 3 are used to achieve imaging for the head-mounted display device. Optionally, the at least two camera components 3 include two RGB camera components 32 and one TOF camera component 33, wherein the RGB camera components 32 are used to acquire image information, and the TOF camera component 33 is used to acquire depth data. Figure 3 As shown, in this embodiment, the two RGB camera components 32 are respectively disposed on the left and right sides of the front shell 11, and the TOF camera component 33 is located in the middle of the front shell 11.

[0046] In this embodiment, the camera assembly 3 is electrically connected to the main circuit board 2 via a flexible connector 4. Exemplarily, the camera assembly 3 and the flexible connector 4 are connected via a plug-in interface, and the main circuit board 2 and the flexible connector 4 can also be connected via a plug-in interface. In this embodiment, at least two camera assemblies 3 are each connected to a first female connector 31, and one end of the flexible connector 4 is provided with a first male connector 41. Electrical connection between the camera assembly 3 and the flexible connector 4 can be achieved through the plugging of the first female connector 31 and the first male connector 41. Figure 5 As shown, both RGB camera components 32 and TOF camera components 33 are connected to the first male connector 41 via the first female connector 31. By setting the first female connector 31 and the first male connector 41, rapid assembly of the camera components 3 and the flexible connector 4 can be achieved, improving assembly efficiency. It should be noted that, alternatively, the flexible connector 4 can be connected to the first female connector 31, while the camera components 3 can be connected to the first male connector 41.

[0047] To facilitate the installation of the camera assembly 3 and the first connecting female connector 31, several intersecting ribs 112 are provided inside the front housing 11. The camera assembly 3 can be placed within the mounting grooves formed by the ribs 112. Screw holes can be provided on the ribs 112, allowing screws to pass through the through holes on the camera assembly 3 and be threaded into the screw holes for further securing. Similarly, the first connecting female connector 31 can be snapped into the mounting grooves formed by the ribs 112 and simultaneously fixed to the front housing 11 with screws. By providing multiple ribs 112 inside the front housing 11, a mounting base for the camera assembly 3 and the first connecting female connector 31 is provided, while also improving the overall strength of the front housing 11.

[0048] like Figure 3 and Figure 6 As shown, the flexible connector 4 can be bent, that is, the flexible connector 4 is a flexible part that can be bent to change its shape, thereby making the flexible connector 4 suitable for installation spaces of different shapes and sizes.

[0049] Optionally, the flexible connector 4 to which one of the RGB camera components 32 is connected and the flexible connector 4 to which the TOF camera component 33 is connected are insulated and stacked. That is, as shown Figure 6 As shown, the flexible connector 4 connected to the RGB camera assembly 32 on the left and the flexible connector 4 connected to the TOF camera assembly 33 are spaced apart, and their projections on the horizontal plane overlap. This layered arrangement effectively utilizes the same installation space, and the flexible connector 4 located below (i.e., Figure 5 The flexible connector 4 connected to the TOF camera assembly 33 is positioned just above the flexible connector 4 (i.e. Figure 5 The flexible connector 4 connecting the RGB camera assembly 32 in the middle makes full use of the space inside the upper flexible connector 4, thus enabling the installation of at least two flexible connectors 4 in the same installation space, effectively saving space and making the overall size of the head-mounted display device smaller. Of course, it is understandable that the head-mounted display device of this application can also stack and install multiple flexible connectors 4 connecting multiple camera assemblies 3 according to the number of camera assemblies 3 and the size and shape of the installation space to achieve a more optimized spatial structure.

[0050] In this embodiment, the flexible connector 4 connected to the RGB camera assembly 32 on the left side is U-shaped, and a portion of the flexible connector 4 connected to the TOF camera assembly 33 is also U-shaped and located within the U-shaped internal space of the flexible connector 4 connected to the RGB camera assembly 32. The other end of the flexible connector 4 connected to the TOF camera assembly 33 has a plate-like structure positioned above the main circuit board 2 so that it can extend to connect to the TOF camera assembly 33. It should be noted that, depending on the shape of the installation space, the flexible connector 4 connected to the RGB camera assembly 32 on the left side and the flexible connector 4 connected to the TOF camera assembly 33 can also be bent multiple times as needed, and in this case, it does not have to be U-shaped.

[0051] The flexible connector 4 connected to the RGB camera assembly 32 located on the right side can also be U-shaped, and can be bent multiple times as needed.

[0052] Preferably, such as Figure 3 or Figure 6 As shown, an indicator light 5 is also connected to the flexible connector 4 to the TOF camera assembly 33. The indicator light 5 is located in the middle of the front shell 11 and serves as a prompt when taking photos or recording videos. By connecting the indicator light 5 in series with the circuit of the flexible connector 4, it is not necessary to add additional connecting lines to achieve circuit conduction of the indicator light 5. This integrates the indicator light 5 onto the flexible connector 4, which reduces production costs (i.e., reduces additional connecting lines) and simplifies the assembly process, thereby improving assembly efficiency.

[0053] In this embodiment, the flexible connector 4 is preferably an FPC flexible board (i.e., a flexible circuit board), which has the characteristics of free bending, folding, rolling, small volume, thinness, free movement and stretching, and can better meet the requirements for installation space utilization.

[0054] The main circuit board 2 described above in this application is installed inside the middle shell 12. A mounting plate (such as a magnesium alloy plate) can be installed inside the middle shell 12, and the main circuit board 2 is fixed to the mounting plate. The main circuit board 2 is a PCB board or an FPC board, such as... Figure 7 and Figure 8As shown, a second female connector 21 is provided on the main circuit board 2. Correspondingly, a second male connector 42 is provided at the other end of the flexible connector 4 (i.e., the end not connected to the camera assembly 3). The second male connector 42 is inserted into the second female connector 21 to realize the electrical connection between the flexible connector 4 and the main circuit board 2, thus ultimately achieving the purpose of electrically connecting the camera assembly 3 to the main circuit board 2 through the flexible connector 4. In this embodiment, considering the stacked arrangement of the flexible connector 4 connected to the RGB camera assembly 32 and the flexible connector 4 connected to the TOF camera assembly 33 on the left side, two second female connectors 21 are provided on the left side of the main circuit board 2 to better adapt to this arrangement structure. The two second female connectors 21 are respectively connected to the flexible connector 4 connected to the RGB camera assembly 32 and the flexible connector 4 connected to the TOF camera assembly 33 on the left side. A second female connector 21 is provided on the right side of the main circuit board 2 to connect to the flexible connector 4 connected to the RGB camera assembly 32 on the right side. It should be noted that the flexible connector 4 can also be connected to the second female connector 21, while the main circuit board 2 can be connected to the second male connector 42.

[0055] In this embodiment of the application, when assembling the head-mounted display device, the RGB camera assembly 32 and the TOF camera assembly 33 are first installed on the front shell 11. At this time, the first connecting female 31 is connected to the RGB camera assembly 32 and the TOF camera assembly 33 and fixed to the front shell 11.

[0056] Subsequently, the main circuit board 2 is installed inside the middle shell 12, at which time the second connecting female 21 is installed on the main circuit board 2.

[0057] Then, the first male connector 41 of the flexible connector 4 is inserted into the first female connector 31 of the camera assembly 3 to achieve electrical connection between the flexible connector 4 and the camera assembly 3. Then, the second male connector 42 of the flexible connector 4 is inserted into the second female connector 21 connected to the main circuit board 2, and the flexible connector 4 is stacked and bent (or the flexible connector 4 can be connected to the main circuit board 2 first, and then connected to the camera assembly 3).

[0058] The front shell 11 is then rotatably connected to the middle shell 12 and rotatably fastened onto the middle shell 12, thus completing the entire assembly process.

[0059] Considering that existing head-mounted display devices all have capacitors on the main circuit board 2 to regulate the voltage of the display screen, these capacitors are typically mounted on the main circuit board 2 with their central axis perpendicular to the main circuit board 2. Since the length of the capacitor along its central axis is relatively large, it is unavoidable that the interior of the housing 1 needs a sufficiently large space to accommodate the capacitor, thus increasing the size of the head-mounted display device. To solve this technical problem, refer to... Figure 9 and Figure 10 The head-mounted display device of this embodiment also includes a display screen and a capacitor 6. The capacitor 6 is electrically connected to the main circuit board 2 with its central axis parallel to the main circuit board 2, and the capacitor 6 is connected to the display screen through the main circuit board 2 to achieve voltage regulation of the display screen. By making the central axis of the capacitor 6 parallel to the main circuit board 2, the space required to install the capacitor 6 can be reduced, thereby reducing the size of the head-mounted display device.

[0060] Specifically, a first FPC flexible board 7 is added to the original circuit board. The first FPC flexible board 7 is set perpendicular to the main circuit board 2, and the length of the first FPC flexible board 7 in the direction perpendicular to the main circuit board 2 is less than the length of the capacitor 6 along its central axis. The capacitor 6 is mounted on the first FPC flexible board 7 and electrically connected to the first FPC flexible board 7. Correspondingly, a set of spring contacts 22 is provided on the main circuit board 2. The set of spring contacts 22 can fix the first FPC flexible board 7 to realize the electrical connection between the capacitor 6 and the main circuit board 2.

[0061] In this embodiment, the first FPC flexible board 7 has an L-shaped structure, and its bottom is provided with a connecting part 71 that connects to the spring contact 22. The connecting part 71 is used to fix the first FPC flexible board 7 and the spring contact 22. The connecting part 71 is arranged parallel to the main circuit board 2 so as to better fit and fix it with the spring contact 22, making the connection between the two more stable. Optionally, the number of capacitors 6 can be set as needed. For example, two capacitors 6 can be fixedly installed on one of the first FPC flexible boards 7, and one capacitor 6 can be installed on the other first FPC flexible board 7. This embodiment does not make a specific limitation.
