[0004] When the battery module needs to be disassembled for maintenance, the entire inner liner of the battery module must be peeled off before the battery module can be opened, which is not conducive to the disassembly and maintenance of the battery module. Summary of the Invention

[0005] The main objective of this invention is to provide an eyeglass case designed to improve the maintainability of the battery module.

[0006] To achieve the above objectives, the present invention proposes a battery module for use in a display device storage box, comprising:

[0007] First shell;

[0008] The second housing includes a housing body and a side plate disposed at one end of the housing body near the first housing. The side plate includes an inner side plate and an outer side plate, both connected to the housing body. The inner side plate is detachably connected to the first housing. The outer side plate covers the first housing and serves as a liner for a display device storage box.

[0009] The battery is installed between the first housing and the second housing.

[0010] In one embodiment, the outer side plate is inclined in a direction away from the inner side plate; and / or

[0011] Along the height direction of the battery module, the height of the outer side plate is greater than the height of the inner side plate.

[0012] In one embodiment, the inner side plate is provided with screw holes, the first housing is provided with screw posts, and the connector passes through the screw holes and the screw posts in sequence to connect the inner side plate and the first housing.

[0013] In one embodiment, a first seal is provided on the end face of the screw post facing the inner side plate; and / or

[0014] A sealing plug is provided between the connector and the screw hole.

[0015] In one embodiment, one of the first housing and the second housing is provided with a sealing groove, and the other housing is provided with a sealing stop. A second sealing element is installed in the sealing groove, and the sealing stop abuts against the second sealing element.

[0016] In one embodiment, a switch hole is provided on the first housing, a switch key is installed in the switch hole, and a sealant is provided between the switch key and the switch hole.

[0017] In one embodiment, the first housing is provided with a USB opening, a USB connector is installed at the USB opening, and a third seal is provided between the USB connector and the USB opening.

[0018] In one embodiment, the first housing is provided with a connection port, the battery module is provided with a flexible circuit board, the flexible circuit board passes through the connection port, and is used to electrically connect with other components of the display device storage box; the flexible circuit board and the connection port are sealed together.

[0019] In one embodiment, a sealing block is provided at the connection port, the connection port having a first end and a second end opposite to each other, one end of the sealing block is used to seal the first end, and the other end of the sealing block is used to seal the flexible circuit board to the second end.

[0020] The present invention also proposes a display device storage box, comprising:

[0021] The box body has a receiving cavity;

[0022] The battery module is housed in the receiving cavity, and the first housing is connected to the box body; and

[0023] A charging module is housed in the receiving cavity, and the charging module is electrically connected to the battery module. The charging module is used to charge the head-mounted display device.

[0024] The present invention also proposes a display component, including the aforementioned display device storage box and a head-mounted display device, wherein the head-mounted display device is housed in the storage cavity and electrically connected to the charging module.

[0025] The technical solution of this invention involves setting a first housing, a second housing, and a battery installed between the first and second housings in a battery module. The second housing includes a housing body and a side plate located at one end of the housing body near the first housing. The side plate includes an inner side plate and an outer side plate, both connected to the housing body. The inner side plate is detachably connected to the first housing, and the outer side plate covers the first housing and serves as a liner for the display device storage box. Compared to the prior art, which uses a single-layer side plate for the second housing and requires a liner to be connected to the outer surfaces of both housings after they are connected, this invention uses a double-layer side plate structure for the second housing. The inner side plate is detachably connected to the first housing to allow for the detachable battery module; the outer side plate covers the first housing, and the liner is placed on the outer surfaces of the outer side plate and the housing body to shield and cover the battery module. Thus, while achieving a detachable connection between the first and second housings, the connection between the battery module and the liner is also achieved, preventing damage to the liner during disassembly of the first and second housings and improving the maintainability of the battery module.

[0046] Head-mounted display devices include VR headsets, mobile VR headsets, standalone VR all-in-one devices, AR / VR hybrid displays, AR glasses, VR glasses, and so on. With the promotion of head-mounted display devices, the demand for convenient rechargeable display device storage boxes is also constantly increasing.

[0047] Generally, a battery module is installed inside the display device storage case to charge the head-mounted display device. To improve the aesthetics of the display device storage case, an inner lining is usually attached to the inside of the case, and the outer surface of the battery module is also lined with an inner lining.

[0048] When the battery module needs to be disassembled for maintenance, the entire inner liner of the battery module must be peeled off before the battery module can be opened, which is not conducive to the disassembly and maintenance of the battery module.

[0049] This invention proposes a battery module for use in a display device storage box.

[0050] Please see Figures 1 to 3 In one embodiment of the present invention, the battery module 100 includes a first housing 200, a second housing 300, and a battery 410. It is understood that the first housing 200 and the second housing 300 are detachably connected, thus facilitating the maintenance of the battery module 100. An installation space is formed between the first housing 200 and the second housing 300, and the battery 410 is installed within this installation space.

[0051] The second housing 300 includes a housing body 301 and a side plate 302. The side plate 302 is located at one end of the housing body 301 near the first housing 200. The side plate 302 includes an inner side plate 310 and an outer side plate 320, both of which are connected to the housing body 301. The inner side plate 310 is detachably connected to the first housing 200. The outer side plate 320 covers the first housing 200 and is used to connect to the inner liner 330 of the display device storage box 500.

[0052] Specifically, the battery module 100 has a certain length, width, and height. The shell body 301 is parallel to the plane formed by the length and width directions of the battery module 100. The side plate 302 is located at one end of the shell body 301 near the first shell 200 and extends towards the first shell 200. The side plate 302 has a double-layer structure, including an inner side plate 310 and an outer side plate 320. The outer side plate 320 is located on the side of the inner side plate 310 away from the center of the second shell 300. The inner side plate 310 is used for detachable connection with the first shell 200, and the outer side plate 320 covers the first shell 200. In one embodiment, the shell body 301, the inner side plate 310, and the outer side plate 320 are integrally formed, which facilitates the processing of the second shell 300.

[0053] In one embodiment, a battery module 100 is installed in a display device storage case 500, and the battery module 100 is used to charge the head-mounted display device. To improve the aesthetics and user comfort of the display device storage case 500, a liner is generally provided inside the case body 510 of the display device storage case 500. The liner serves two purposes: firstly, to conceal the structural components inside the display device storage case 500, and secondly, to improve the tactile feel of the display device storage case 500.

[0054] When the battery module 100 is installed in the display device storage box 500, the first housing 200 of the battery module 100 is connected to the box body 510 of the display device storage box 500. When the inner side of the display device storage box 500 is provided with a liner, for the battery module 100, since the outer panel 320 covers the side wall of the first housing 200, that is, the first housing 200 is covered by the second housing 300, there is no need to provide a liner on the first housing 200. Only the liner 330 needs to be provided on the outer surface of the second housing 300, that is, on the outer surface of the outer panel 320 and the outer surface of the shell body 301. In this way, the battery module 100 can be covered, thereby improving the aesthetics of the battery module 100 and the overall uniformity of the display device storage box 500.

[0055] Understandably, the inner liner 330 on the battery module 100 and the inner liner inside the display device storage box 500 are separate structures, which facilitates the detachment of the battery module 100 and the box body 510 of the display device storage box 500. In one embodiment, the inner liner 330 on the battery module 100 and the inner liner inside the box body 510 are made of the same material, which is beneficial to the overall uniformity of the display device storage box 500. In one embodiment, the inner liner 330 is made of leather and is attached to the outer surface of the second housing 300 and the inner surface of the box body 510 by adhesive.

[0056] Thus, the side panel 302 of the second housing 300 is configured as a double-layer structure. The inner side panel 310 is used for detachable connection with the first housing 200, thereby enabling the battery module 100 to be detachable. The outer side panel 320 is used for connection to the inner liner 330 of the display device storage box 500. In this way, the inner liner 330 is located on the outer surface of the second housing 300, that is, on the outer surface of the housing body 301 and the outer side panel 320, which can cover the battery module 100, improve the aesthetics of the battery module 100, and at the same time avoid damage to the inner liner 330 when the first housing 200 and the second housing 300 are disassembled.

[0057] The technical solution of the present invention provides a first housing 200, a second housing 300, and a battery 410 installed between the first housing 200 and the second housing 300 in a battery module 100. The second housing 300 includes a housing body 301 and a side plate 302 disposed at one end of the housing body 301 near the first housing 200. The side plate 302 includes an inner side plate 310 and an outer side plate 320, both of which are connected to the housing body 301. The inner side plate 310 is used for detachable connection with the first housing 200, and the outer side plate 320 covers the first housing 200 and is used for connection to the inner liner 330 of the display device storage box 500. Therefore, compared to the existing technology where the second housing 300 has a single-layer side panel, requiring an inner liner 330 to be connected to the outer surfaces of the first housing 200 and the second housing 300 after they are connected, this invention sets the second housing 300 as a double-layer side panel 302 structure. The inner side panel 310 is detachably connected to the first housing 200 to allow for the detachable battery module 100; the outer side panel 320 covers the first housing 200, and the inner liner 330 is placed on the outer surfaces of the outer side panel 320 and the housing body 301, thus providing both shielding and coverage for the battery module 100. In this way, while achieving a detachable connection between the first housing 200 and the second housing 300, the connection between the battery module 100 and the inner liner 330 is also achieved, preventing damage to the inner liner 330 during disassembly of the first housing 200 and the second housing 300, and improving the maintainability of the battery module 100.

[0058] Please see Figure 3 In an embodiment of the present invention, the outer side plate 320 is inclined in a direction away from the inner side plate 310; and / or, along the height direction of the battery module 100, the height of the outer side plate 320 is greater than the height of the inner side plate 310.

[0059] Specifically, in one embodiment, the outer side plate 320 is inclined in a direction away from the inner side plate 310 in the direction close to the first housing 200. This inclined arrangement of the outer side plate 320 facilitates the connection between the inner liner 330 and the second housing 300. Of course, in other embodiments, the outer side plate 320 can also be parallel to the inner side plate 310, thus allowing for connection of the inner liner 330.

[0060] Understandably, the battery module 100 has a certain height. Along the height direction of the battery module 100, the height of the outer side plate 320 is greater than the height of the inner side plate 310, so that the outer side plate 320 covers the side wall of the first housing 200. In one embodiment, the height of the outer side plate 320 is equal to the sum of the height of the inner side plate 310 and the height of the side wall of the first housing 200. In this way, the outer side plate 320 can completely cover the side wall of the first housing 200, which is beneficial to the overall aesthetics of the battery module 100.

[0061] Please see Figure 2 and Figure 3 In the embodiment shown in the figures of this invention, both the first housing 200 and the second housing 300 are wedge-shaped structures, and the two wedge-shaped structures are fitted together so that the two are connected to form an approximate trapezoidal structure. The wedge-shaped structure helps to avoid relative displacement and deviation between the first housing 200 and the second housing 300, and facilitates the rapid positioning and precise assembly of the first housing 200 and the second housing 300.

[0062] Understandably, after the battery module 100 is installed in the display device storage box 500, the bottom wall of the first housing 200 needs to be in contact with the bottom wall of the display device storage box 500. In one embodiment, the battery module 100 needs to be provided with an electrical connection port for external electrical connection, such as a USB interface. In this case, the battery module 100 needs to be located on the side closer to the display device storage box 500. Thus, the bottom wall of the battery module 100 and the side wall with the external electrical connection port 250 do not need to be covered by the inner liner 330.

[0063] At this time, the second housing 300 includes a housing body 301 and a side plate 302. Along the circumference of the housing body 301, the side plate 302 includes a left side wall and a right side wall disposed opposite to each other, and a front side wall between the left side wall and the right side wall. In one embodiment, both the left side wall and the right side wall include an inner side plate 310 and an outer side plate 320 located outside the inner side plate 310, wherein the outer side plate 320 is inclined relative to the inner side plate 310, and the height of the outer side plate 320 is greater than that of the inner side plate 310. The front side wall includes an inner side plate 310 and an outer side plate 320 located outside the inner side plate 310. Since the first housing 200 and the second housing 300 are arranged in a wedge-shaped structure and the battery module 100 is arranged in a trapezoidal structure, the outer side plate 320 of the front side wall can continue to extend along the direction of the inner side plate 310 of the front side wall. At this time, the inclination angle of the outer side plate 320 and the inner side plate 310 in the front side wall is the same, and the height of the outer side plate 320 is greater than that of the inner side plate 310.

[0064] Of course, in other embodiments, both the first housing 200 and the second housing 300 can be rectangular, and the two rectangular structures can be fitted together to form a rectangular structure after connection. In one embodiment, the second housing 300 includes a housing body 301 and a side plate 302. Along the circumference of the housing body 301, the side plate 302 includes a left side wall and a right side wall opposite to each other, as well as a front side wall and a rear side wall opposite to each other. In one embodiment, the left side wall, the right side wall, the front side wall, and the rear side wall all include an inner side plate 310 and an outer side plate 320. The height of the outer side plate 320 is greater than that of the inner side plate 310, and the outer side plate 320 is inclined or parallel to the inner side plate 310. In another embodiment, since the rear side wall does not need to be lined with an inner liner 330, only the inner side plate 310 can be provided on the rear side wall.

[0065] Please see Figures 2 to 4 In an embodiment of the present invention, the inner side plate 310 is provided with screw holes 311, the first housing 200 is provided with screw posts 210, and the connector 313 passes through the screw holes 311 and the screw posts 210 in sequence to connect the inner side plate 310 and the first housing 200.

[0066] Specifically, in one embodiment, the first housing 200 and the second housing 300 are detachably connected by screw fastening. The inner side plate 310 has screw holes 311, and the first housing 200 has corresponding screw posts 210. When the first housing 200 and the second housing 300 are closed, the screw holes 311 and screw posts 210 correspond, and the connector 313 passes through the screw holes 311 and screw posts 210 in sequence, thereby connecting the first housing 200 and the inner side plate 310 together. In one embodiment, the connector 313 is configured as a screw, and both the screw holes 311 and screw posts 210 are threaded. Of course, the connector 313 can also be a connecting pin, etc.

[0067] In this embodiment, the first housing 200 and the second housing 300 are detachably connected by screws. Therefore, the screws and other connecting parts 313 should be easily detachable from the outside of either the first housing 200 or the second housing 300. It is understood that the screw hole 311 is located on the inner side plate 310 of the second housing 300, penetrating the inner side plate 310 and protruding from the outer surface of the second housing 300 to facilitate the attachment and removal of the screws and other connecting parts 313. Simultaneously, the inner liner 330 is located on the outer surface of the second housing 300, i.e., the outer surface of the housing body 301 and the outer side plate 320. To facilitate the attachment and removal of the screws, the inner liner 330 has an inner liner notch 331 at the location of the screw hole 311. That is, the inner liner 330 is not connected at the screw hole 311. After the first housing 200 and the second housing 300 are connected, the inner liner patch is then connected at the screw hole 311. The size of the inner liner patch matches the screw hole 311. In one embodiment, the material of the inner liner patch is consistent with the material of the inner liner 330 outside the second housing 300, which is beneficial to the overall consistency of the appearance of the battery module 100. Thus, when it is necessary to disassemble the battery module 100, simply peel off the inner liner patch and loosen the screws and other connecting parts 313 to separate the first housing 200 and the second housing 300 without damaging the structure of the inner liner 330 outside the second housing 300, thereby improving the maintainability of the battery module 100.

[0068] In one embodiment, one of the first housing 200 and the second housing 300 is provided with a slot (not shown), and the other is provided with a buckle 316. The buckle 316 engages with the slot, thereby connecting the first housing 200 and the second housing 300. This snap-fit ​​connection allows for a detachable connection between the first housing 200 and the second housing 300, improving assembly efficiency.

[0069] In one embodiment, the first housing 200 and the second housing 300 are simultaneously fastened with screws and snapped together to achieve a detachable connection. This ensures the stability and reliability of the connection between the first housing 200 and the second housing 300, and also helps to improve the efficiency of the connection between the two.

[0070] Please see Figure 4 In an embodiment of the present invention, a first sealing element 211 is provided on the end face of the screw post 210 facing the inner side plate 310; and / or, a sealing plug 312 is provided between the connector 313 and the screw hole 311.

[0071] Specifically, to improve the sealing performance of the battery module 100, a sealing arrangement is provided at the connection between the first housing 200 and the second housing 300. In one embodiment, a first sealing element 211 is provided on the end face of the screw post 210 facing the inner side plate 310. Thus, when the first housing 200 and the second housing 300 are connected, the first sealing element 211 is pressed between the end face of the screw post 210 and the end face of the screw hole 311, thereby improving the sealing performance of the connection between the screw post 210 and the screw hole 311. In one embodiment, the first sealing element 211 is made of silicone, rubber, foam, etc.

[0072] In one embodiment, after the connector 313 passes through the screw hole 311 and is tightened with the screw post 210, the end face of the connector 313 away from the screw hole 311 is located inside the screw hole 311. To prevent moisture from seeping into the screw hole 311, a sealing plug 312 is provided between the connector 313 and the screw hole 311, thereby further improving the sealing performance at the connection between the first housing 200 and the second housing 300. In one embodiment, the upper end face of the sealing plug 312 is flush with the upper surface of the inner side plate 310, which is beneficial to the aesthetics of the second housing 300. In one embodiment, the sealing plug 312 is made of natural rubber, butyl rubber, etc.

[0073] Please see Figures 2 to 4 In an embodiment of the present invention, one of the first housing 200 and the second housing 300 is provided with a sealing groove 315, and the other is provided with a sealing stop 220. A second sealing member 314 is installed in the sealing groove 315, and the sealing stop 220 abuts against the second sealing member 314.

[0074] Specifically, in the embodiment shown in the figures of this invention, the first housing 200 is provided with a sealing stop 220, and the second housing 300 is provided with a sealing groove 315. A second sealing element 314 is installed in the sealing groove 315. When the first housing 200 and the second housing 300 are closed and connected, the second sealing element 314 in the sealing groove 315 abuts against the sealing stop 220, thereby improving the sealing performance at the connection between the first housing 200 and the second housing 300. The sealing stop 220 and the sealing groove 315 extend circumferentially around the first housing 200 and the second housing 300, respectively, and the second sealing element 314 extends along the sealing groove 315. In this way, a circumference at the connection between the first housing 200 and the second housing 300 can be sealed, further improving the sealing performance of the connection between the first housing 200 and the second housing 300. In one embodiment, the second sealing element 314 is configured as a silicone or rubber sealing ring.

[0075] Of course, in other embodiments, the first housing 200 may be provided with a sealing groove 315 and the second housing 300 may be provided with a sealing stop 220, which is not limited here.

[0076] Please see Figure 5 In an embodiment of the present invention, a switch hole 230 is provided on the first housing 200, a switch key 420 is installed in the switch hole 230, and a sealant is provided between the switch key 420 and the switch hole 230.

[0077] Specifically, the battery module 100 is also equipped with a power switch 420, which can be used to control the charging operation of the battery module 100.

To improve the sealing of the battery module 100, a sealed arrangement is provided between the connection port 250 and the flexible circuit board 440.

[0086] Understandably, the battery module 100 includes a detachably connected first housing 200 and a second housing 300, wherein the outer surface of the second housing 300 is provided with an inner liner 330. Therefore, compared to placing the connection port 250 on the second housing 300, this invention places the connection port 250 on the first housing 200, thereby avoiding the need for a corresponding clearance notch in the inner liner 330. This facilitates the connection between the inner liner 330 and the second housing 300, improves the integrity of the inner liner 330 on the second housing 300, and also enhances the overall aesthetics of the battery module 100. In one embodiment, the connection port 250 is positioned close to the USB opening 240, which further improves the overall aesthetics of the battery module 100.

[0087] Of course, in other embodiments, the flexible circuit board 440 may also be disposed in the charging module 520 and extend into the battery module 100 through the connection port 250 to realize the electrical connection between the battery module 100 and the charging module 520. Alternatively, the flexible circuit board 440 may also be an additional electrical connector 313, with its two ends electrically connected to the battery module 100 and the charging module 520 respectively.

[0088] In other embodiments, the component electrically connected to the battery module 100 may also be a control module, which can be used to control functions such as Bluetooth of the head-mounted display device in the display device storage box 500.
