[0002] AR / VR glasses are currently gaining popularity, and dust and water resistance requirements for practical applications have been added to product application requirements. However, due to the large size of the front and back shells of AR / VR glasses and the complex structure, it is difficult to achieve a seal of IP65 or higher. Therefore, the general waterproof requirements for AR / VR glasses only require an IPX4 level of waterproofing, or simply do not require waterproofing or dust resistance. In practical applications, especially industrial applications, it is often necessary to meet the requirements of high dust environments and rain or seawater rinsing, so a waterproof level of at least IPX5 is required.

[0003] Currently, existing technologies for setting seals on the structure of the front and rear shells of AR / VR glasses can be achieved by applying hot melt adhesive between the front and rear shells, but this method has poor sealing performance. Alternatively, seals can be manually installed between the front and rear shells, but this method is difficult to implement due to the complex fit between the front and rear shells and the long span of the structure. Summary of the Invention

[0004] The main objective of this invention is to provide a housing assembly, a wearable device, and a method for assembling the housing assembly, aiming to solve the problems of poor sealing effect and difficult installation of the sealing gaskets in the front and rear shells of existing sealed AR / VR glasses.

[0005] To achieve the above objectives, the present invention provides a housing assembly for use in wearable devices, comprising:

[0006] First shell;

[0007] The second housing is disposed on the first housing;

[0008] A sealing body is disposed between the first housing and the second housing to seal the gap between the first housing and the second housing. The sealing body is formed by curing photosensitive adhesive by ultraviolet light irradiation.

[0009] In one embodiment, the periphery of the first housing is provided with a first edge portion;

[0010] The second housing has a second edge portion around its periphery, and the second edge portion has a connecting groove for the first edge portion to be inserted into, and the sealing body is disposed in the connecting groove.

[0011] In one embodiment, a rib protrudes from the end face of the first edge portion toward the second edge portion, and the side of the rib and the end face of the first edge portion form a clearance groove, which is correspondingly provided with a portion of the second edge portion;

[0012] And / or, the side of the rib is inclined, and the thickness of the rib gradually decreases along the extension direction of the first edge.

[0013] In one embodiment, the sealing body comprises a polymer resin and silicon dioxide;

[0014] The polymer resin has a mass fraction of 30%-50%; and

[0015] The silicon dioxide comprises 20%-50% by mass.

[0016] In one embodiment, the density of the sealing body is 1.05 g / ml;

[0017] And / or, the viscosity of the sealant is 18000-22000 cps;

[0018] And / or, the hardness of the sealing body is less than Shore A12;

[0019] And / or, the tensile strength of the seal is greater than or equal to 2 MPa.

[0020] In one embodiment, the housing assembly further includes screw connections;

[0021] One of the first housing and the second housing is provided with a through hole, and the other is provided with a screw hole;

[0022] The threaded connector passes through the through hole and is threadedly connected to the threaded hole;

[0023] And / or, a sealing gasket is provided on the outer periphery of the screw connector, the sealing gasket being used to seal the gap between the screw connector and the through hole.

[0024] The present invention also proposes a wearable device, including a housing assembly as described in the above embodiments, wherein the wearable device is AR glasses, VR glasses, or headphones.

[0025] The present invention also proposes a method for assembling a housing assembly, comprising:

[0026] Apply photosensitive adhesive to the first housing or the second housing;

[0027] The photosensitive adhesive is irradiated with an ultraviolet lamp to cure it and form a sealant.

[0028] The first housing and the second housing are closed together so that the sealing body deforms and seals the gap between the first housing and the second housing.

[0029] In one embodiment, one of the first housing and the second housing has a connecting groove recessed around its periphery, and the other has a rib corresponding to the connecting groove. The connecting groove is used for the rib to be inserted into, and the photosensitive adhesive is coated inside the connecting groove.

[0030] In one embodiment, the ultraviolet lamp has a power of 3W-5W, a wavelength of 350nm-380nm, and an irradiation duration of 8s-15s.

[0031] The technical solution of the present invention is that the sealing body is formed by curing liquid photosensitive adhesive after being irradiated by ultraviolet light. Therefore, when the liquid photosensitive adhesive is applied to the first shell or the second shell, the sealing body used for sealing will not be difficult to lay and install due to the intricate structure or long span of the structure on the first shell or the second shell. This setting makes the operation of laying the sealing body on the first shell or the second shell simple and the sealing effect good. Attached Figure Description

[0042] AR / VR glasses are currently gaining popularity, and dust and water resistance requirements for practical applications have been added to product application requirements. However, due to the large size of the front and back shells of AR / VR glasses and the complex structure, it is difficult to achieve a seal of IP65 or higher. Therefore, the general waterproof requirements for AR / VR glasses only require an IPX4 level of waterproofing, or simply do not require waterproofing or dust resistance. In practical applications, especially industrial applications, it is often necessary to meet the requirements of high dust environments and rain or seawater rinsing, so a waterproof level of at least IPX5 is required.

[0043] Currently, existing technologies for setting seals on the structure of the front and rear shells of AR / VR glasses can be achieved by applying hot melt adhesive between the front and rear shells, but this method has poor sealing performance. Alternatively, seals can be manually installed between the front and rear shells, but this method is difficult to implement due to the complex fit between the front and rear shells and the long span of the structure.

[0044] The present invention proposes a housing assembly 100.

[0045] Please refer to Figures 1 and 2. In one embodiment of the present invention, the housing assembly 100 is applied to a wearable device and includes a first housing 10, a second housing 20, and a sealing body 30. The second housing 20 is disposed on the first housing 10. The sealing body 30 is disposed between the first housing 10 and the second housing 20 to seal the gap between the first housing 10 and the second housing 20. The sealing body 30 is formed by curing photosensitive adhesive by ultraviolet light irradiation.

[0046] The housing assembly 100 in the technical solution of this invention includes a first housing 10, a second housing 20, and a sealing body 30. The first housing 10 or the second housing 20 has a mounting surface for mounting electronic components. When the first housing 10 and the second housing 20 are closed, they form a cavity for accommodating electronic components. To allow external water or dust to enter the cavity through the gap between the first housing 10 and the second housing 20, in this embodiment, a sealing body 30 is provided between the first housing 10 and the second housing 20. The sealing body 30 is formed by curing photosensitive adhesive after irradiation with ultraviolet light. Because the sealing body 30 is initially photosensitive adhesive, and photosensitive adhesive is in a fluid state, when placing the sealing body 30 on the first housing 10 or the second housing 20, the user can coat the fluid photosensitive adhesive along the periphery of the first housing 10 or the second housing 20 according to the actual situation. After coating, the photosensitive adhesive is irradiated with an ultraviolet lamp. When the photosensitive adhesive is irradiated with ultraviolet light, the photoinitiator in the photosensitive adhesive absorbs light energy and produces… Free radicals or ions are generated, triggering a cross-linking reaction of the adhesive molecules. This cross-linking reaction causes the photosensitive adhesive to gradually cure, forming a sealing body 30. After the photosensitive adhesive is cured by ultraviolet light to form the sealing body 30, the user can cover the first shell 10 and the second shell 20 together, so that the first shell 10 and the second shell 20 are close to each other to compress the sealing body 30. The sealing body 30 deforms under force, and the deformed sealing body 30 fills the gap between the first shell 10 and the second shell 20, thereby achieving an excellent sealing effect. Since the sealing body 30 is formed by curing liquid photosensitive adhesive after being irradiated by ultraviolet light, when the liquid photosensitive adhesive is applied to the first shell 10 or the second shell 20, the sealing body 30 used for sealing will not be difficult to lay and install due to the intricate structure or long span of the structure on the first shell 10 or the second shell 20. This design makes the operation of laying the sealing body 30 on the first shell 10 or the second shell 20 simple and the sealing effect good.

[0047] In one embodiment, as shown in Figures 1 and 2, the first housing 10 has a first edge portion 11 around its periphery; the second housing 20 has a second edge portion 21 around its periphery. The second edge portion 21 has a connecting groove 211 for the first edge portion 11 to be inserted into, and the sealing body 30 is disposed in the connecting groove 211. To improve the connection effect after the first housing 10 and the second housing 20 are closed, in this embodiment, the first edge portion 11 is provided around the periphery of the first housing 10, and the second edge portion 21 is provided around the periphery of the second housing 20. The second edge portion 21 has a recessed connecting groove 211 for the first edge portion 11 on the first housing 10 to be inserted into. Furthermore, in this embodiment, to prevent the fluid photosensitive adhesive from flowing freely on the second housing 20, when applying the fluid photosensitive adhesive to the second housing 20, a tool can be used to apply the fluid photosensitive adhesive to the connecting groove formed on the recessed second edge portion 21 of the second housing 20. After the fluid photosensitive adhesive is applied to the connecting groove 211, the user can place the second housing 20 on a horizontal surface and keep it stationary so that the fluid photosensitive adhesive in the connecting groove 211 is in a horizontal state. Then, the user can irradiate the photosensitive adhesive in the connecting groove 211 with an ultraviolet lamp so that the photosensitive adhesive in the connecting groove 211 is cured to form a sealing body 30. Since the sealing body 30 is set in the connecting groove 211, and the first housing 10 is inserted into the connecting groove 211 and covers the second housing 20 through the first edge portion 11, the sealing body 30 can deform after being subjected to force to seal the gap between the first edge portion 11 and the connecting groove 211.

[0048] Furthermore, a rib 111 protrudes from the end face of the first edge portion 11 facing the second edge portion 21. The side of the rib 111 and the end face of the first edge portion 11 form a relief groove 112, which corresponds to a portion of the second edge portion 21. To better seal the gap between the first edge portion 11 and the connecting groove 211 after the sealing body 30 is deformed under force, in this embodiment, a rib 111 protrudes from the end face of the first edge portion 11 facing the second edge portion 21. The rib 111 is used for connection and insertion with the above embodiment. Since the rib 111 does not occupy the entire end face of the first edge portion 11 facing the second edge portion 21, the side of the rib 111 will be connected to the first edge portion 21. The end face of part 11 forms a relief groove 112. When the rib 111 is located in the middle of the end face of the first edge part 11, two relief grooves 112 are formed. When the rib 111 is located on the side of the end face of the first edge part 11 close to the receiving cavity, one relief groove 112 is formed. The number of relief grooves 112 is not specifically limited. When the rib 111 is inserted into the connecting groove 211, the end face of the relief groove 112 corresponding to the second edge part 21 will fit against the second edge part 21. A gap with an included angle will be formed between the relief groove 112 and the second edge part 21. This gap allows the sealing body 30 to deform under force, thereby further improving the sealing effect of the sealing body 30 on the first housing 10 and the second housing 20.

[0049] Furthermore, the side of the rib 111 is inclined, and the thickness of the rib 111 gradually decreases along the extension direction of the first edge portion 11. To improve the sealing effect after the sealing body 30 deforms, in this embodiment, the side of the rib 111 is inclined, that is, it forms the side of the clearance groove 112 by surrounding the end face of the first edge portion 11 towards the second edge portion 21. Because the side of the rib 111 is inclined, the thickness of the rib 111 decreases along the direction from the first edge to the rib 111. This arrangement allows the gap between the side of the rib 111 and the wall of the connecting groove 211 to gradually decrease along the direction from the bottom to the opening of the connecting groove 211 when the rib 111 is inserted into the connecting groove 211. When the rib 111 is inserted into the connecting groove 211 and compresses the sealing body 30, the sealing body 30 deforms and can extend to fill the gap between the side of the rib 111 and the wall of the connecting groove 211, thereby improving the sealing effect.

[0050] In one embodiment, the sealing body 30 comprises a polymer resin and silica; the polymer resin comprises 30%-50% by mass; and the silica comprises 20%-50% by mass. In this embodiment, the sealing body 30 comprises 30% polymer resin, 50% silica, and 20% other substances. These other substances can be colorants, adhesives, or photoinitiators, and are not limited in this regard. In this embodiment, the sealing body 30 configured in this way has an ultra-soft effect, with a hardness less than Shore A12. The sealing body 30 has low adhesive force, and its environmental protection level can reach food grade. It also has good rebound performance. In this embodiment, because its hardness is less than Shore A12 and it has an ultra-soft effect, the sealing body 30 is more likely to deform under stress to seal the gap between the first housing 10 and the second housing 20, thereby improving the sealing effect. Furthermore, because the sealing body 30 has low adhesive force, it can be easily removed from the first housing 10 or the second housing 20. When the housing 20 is removed, it does not create a strong bond between the housing used to hold the photosensitive adhesive and the cover housing, thus facilitating the later disassembly of the first housing 10 and the second housing 20 to repair or replace the electronic components located in the receiving cavity. Furthermore, due to its high environmental protection level, it poses no health risks to users. Also, because the sealing body 30 has good rebound performance, it can be reused repeatedly and is not rendered unusable after the first housing 10 and the second housing 20 are disassembled. In other embodiments, the sealing body 30 comprises 50% polymer resin and 50% silica. The difference between the sealing body 30 configured in this way and the one described above is that the adhesive force of the sealing body 30 in this embodiment is greater than that in the above embodiment, the hardness is slightly increased, and other properties are maintained.

[0051] In one embodiment, the density of the sealing body 30 is 1.05 g / ml; and / or, the viscosity of the sealing body 30 is 18000-22000 cps; and / or, the tensile strength of the sealing body 30 is greater than or equal to 2 MPa. In this embodiment, the density of the sealing body 30 is 1.05 g / ml, the viscosity of the sealing body 30 is 20000 cps, and the tensile strength of the sealing body 30 is greater than or equal to 2 MPa.

[0052] In one embodiment, as shown in Figures 1 and 2, the housing assembly 100 further includes a screw connector 40; one of the first housing 10 and the second housing 20 is provided with a through hole 22, and the other is provided with a screw hole 12; the screw connector 40 passes through the through hole 22 and is threadedly connected to the screw hole 12; and / or, a sealing gasket is provided on the outer periphery of the screw connector 40, the sealing gasket being used to seal the gap between the screw connector 40 and the through hole 22. To ensure a tight fit between the first housing 10 and the second housing 20, in this embodiment, the first housing 10 and the second housing 20 are screwed together by a screw connector 40. One of the first housing 10 and the second housing 20 has a through hole 22, and the other has a screw hole 12. The screw connector 40 passes through the through hole 22 and is threaded into the screw hole 12. For example, the screw hole 12 is provided on the first housing 10, and the through hole 22 is provided on the second housing 20. When the first housing 10 and the second housing 20 are closed, the through hole 22 corresponds to the screw hole 12. The user can then insert the screw connector 40 through the through hole 22 into the screw hole 12 and install it into the screw hole 12 by screwing. When the screw connector 40 is screwed into the screw hole 12, it can compress the first housing 10 and the second housing 20. The first housing 10 and the second housing 20 are brought closer together, so that they fit tightly together. In this embodiment, since the sealing body 30 is disposed between the first housing 10 and the second housing 20, the sealing body 30 will deform under force when the first housing 10 and the second housing 20 are tightly fitted together, and then seal the gap between the first housing 10 and the second housing 20. In this embodiment, the screw hole 12 does not penetrate the first housing 10, but the through hole 22 penetrates the second housing 20. In order to prevent external water and dust from entering the receiving cavity through the gap between the screw member 40 and the through hole 22, in this embodiment, a sealing gasket is provided on the outer periphery of the screw member 40. When the screw member 40 passes through the through hole 22 and is screwed into the screw hole 12, the end of the screw member 40 will squeeze the sealing gasket so that the sealing gasket seals the gap between the through hole 22 and the end of the screw member 40.

[0053] The present invention also proposes a wearable device, which includes a housing assembly 100 as described in the above embodiments. The specific structure of the housing assembly 100 is as described in the above embodiments. Since this wearable device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The wearable device can be AR glasses, VR glasses, or headphones, and is not limited thereto.

[0054] The present invention also proposes a method for assembling a housing assembly 100, the method comprising: applying photosensitive adhesive to a first housing 10 or a second housing 20; irradiating the photosensitive adhesive with an ultraviolet lamp to cure the photosensitive adhesive to form a sealing body 30; and covering the first housing 10 and the second housing 20 to seal the gap between the first housing 10 and the second housing 20 after the sealing body 30 is deformed. When assembling the housing assembly 100, a fluid photosensitive adhesive can be first applied to the first housing 10 or the second housing 20 that make up the housing assembly 100. After application, the two housings coated with the photosensitive adhesive can be irradiated with an ultraviolet lamp. When the photosensitive adhesive is irradiated by ultraviolet light, the photoinitiator in the photosensitive adhesive absorbs light energy and generates free radicals or ions, thereby initiating a cross-linking reaction of the adhesive molecules. This cross-linking reaction causes the photosensitive adhesive to gradually solidify, thus solidifying the photosensitive adhesive to form a sealant 30. In this embodiment, the sealant 30 is made of the same material as the sealant 30 described in the above embodiments, so the sealant 30 has at least all the advantages brought about by the technical solutions of the above embodiments. The effects will not be elaborated here. This assembly method not only allows users to easily install the sealing body 30 on complex and long-span shells, but also ensures that the sealing body 30 has low hardness, low adhesion, high environmental protection level, and good rebound performance. This allows the sealing body 30 to better seal the gap between the first shell 10 and the second shell 20 after they are closed, so that the closed shell assembly 100 has a dustproof and waterproof rating of IPX7 or higher. Furthermore, the sealing body 30, with this configuration, does not hinder the disassembly of the first shell 10 and the second shell 20 and can be reused. This configuration can significantly reduce the installation time of the sealing body 30.

[0055] In one embodiment, one of the first housing 10 and the second housing 20 has a recessed connecting groove 211 on its periphery, and the other has a corresponding rib 111. The connecting groove 211 is used for the rib 111 to be inserted into, and the photosensitive adhesive is coated inside the connecting groove 211. To prevent the photosensitive adhesive from flowing freely when coated on either the first housing 10 or the second housing 20, in this embodiment, a connecting groove 211 is recessed on the periphery of either the first housing 10 or the second housing 20. When coating the photosensitive adhesive, it can be coated along the extending direction of the connecting groove 211. In this way, the photosensitive adhesive can only flow within the connecting groove 211 without overflowing, resulting in higher coating efficiency.

[0056] Before applying the photosensitive adhesive to the first housing 10 or the second housing 20, the housing to be coated with the photosensitive adhesive can be installed on the positioning device. The connecting groove 211 on the housing can be cleaned with a cleaning device. Then, the photosensitive adhesive can be applied to the connecting groove 211 of the housing using a coating tool or coating equipment. After coating, the housing can be shaken back and forth and left and right to allow the photosensitive adhesive to flow to every corner of the connecting groove 211. Then, the housing can be placed on a horizontal surface and left and right can be left to stand still for a period of time to make the surface of the photosensitive adhesive in the connecting groove 211 horizontal.

[0057] In one embodiment, the ultraviolet lamp has a power of 3W-5W, a wavelength of 350nm-380nm, and an irradiation duration of 8s-15s. In this embodiment, the ultraviolet lamp has a power of 4W, a wavelength of 365nm, and an irradiation duration of 10s.

[0058] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
