In the invention, when the battery 130 in the battery compartment 100 is burned, the smoke can be discharged to the smoke discharge channel 220 through the smoke outlet 120 arranged on the smoke discharge channel, and the smoke can be finally discharged to the external environment from the smoke outlet 210 through the guidance of the smoke discharge channel 220, so that the heat generated by the combustion of the battery 130 can be discharged to the external environment along with the smoke, thereby avoiding the damage to other components. Therefore, when the battery 130 burns, the head-mounted device of the invention can exhaust smoke to the external environment, so that the safety performance of the head-mounted device can be improved.

Without loss of generality, in this embodiment, the head-mounted device is VR (Virtual Reality) glasses, but of course, in other embodiments, the head-mounted device may also be AR (Augmented Reality) glasses, MR (mixed Reality) glasses, or the like.

Further, in the present embodiment, as shown in fig. 7, a fireproof sleeve 111 is disposed in the battery slot 110, and the fireproof sleeve 111 is used for covering the battery 130. It will be appreciated that the fire-resistant sheath 111 should be flame-retardant to delay the spread of fire when the battery 130 is burned, so that the user is assured sufficient time to remove the headset under the protection of the fire-resistant sheath 111. Furthermore, the fireproof sleeve 111 should be made of V0 fireproof material to improve its fire resistance, thereby improving the safety performance of the head-mounted device.

Further, in the present embodiment, as shown in fig. 7, the battery slot 110 is used for the battery 130 to be in clearance fit, so that the battery 130 is spaced from the inner wall surface of the battery compartment 100. It will be appreciated that as the cell 130 burns, its volume will expand. In this embodiment, a fit gap exists between the battery 130 and the battery slot 110 to allow the battery 130 to expand, so as to prevent the explosion caused by the over-extrusion of the wall surface of the battery compartment 100 by the burning battery 130; further, the fit clearance should be at least sufficient to allow the battery 130 to expand by 10%, so as to ensure that there is enough space for the battery 130 to expand.

Further, in the present embodiment, as shown in fig. 2 and 5, a support 300 is disposed in the housing 200, the battery compartment 100 is mounted on the support 300, the smoke evacuation channel 220 includes a first smoke evacuation section 221 disposed through the support 300, the first smoke evacuation section 221 has a first channel port 2211 disposed near the smoke outlet 120; a first sealing ring 500 is disposed between the bracket 300 and the battery compartment 100, and one side of the first sealing ring 500 surrounds the periphery of the first passage port 2211, and the other side of the first sealing ring 500 surrounds the periphery of the smoke outlet 120. The first sealing ring 500 is disposed at a seam between the first smoke discharging section 221 and the battery compartment 100 to seal between the smoke outlet 120 and the first passage port 2211, so that when the battery 130 is burned, smoke discharged from the smoke outlet 120 cannot diffuse to other positions of the housing 200 in the process of passing through the first smoke discharging section 221, and the smoke can be discharged out of the housing 200 through the smoke discharging passage 220 and only from the smoke discharging port 210, thereby improving the safety performance of the head-mounted device. Of course, in other embodiments, the bracket 300 may be integrally formed with the battery compartment 100, so as to ensure the sealing performance at the connection between the bracket 300 and the battery compartment 100 without providing a sealing ring; the joint between the smoke outlet 120 and the first passage 2211 can also be sealed by gluing, so that a seam between the first smoke exhaust section 221 and the battery compartment 100 can also be avoided, and further, a thermosetting adhesive can be used for bonding, so that bonding failure caused by temperature rise in the smoke exhaust passage 220 when the battery 130 is burnt can be avoided; alternatively, the smoke evacuation channel 220 does not extend through the bracket 300, but is disposed in the housing 200 separately from the bracket 300.

Further, in this embodiment, as shown in fig. 2 and fig. 5, a fan 400 is disposed on a side of the bracket 300 away from the battery compartment 100, the housing 200 is provided with an air outlet corresponding to the fan 400, and the smoke outlet 210 is the air outlet; the housing 200 is further provided with an air outlet channel corresponding to the fan 400, the smoke exhaust channel 220 further includes a second smoke exhaust section 222 communicated with the first smoke exhaust section 221, and the second smoke exhaust section 222 is the air outlet channel. In this way, when the battery 130 is burned, heat can be dissipated by the fan 400, and smoke discharge is accelerated, so as to further improve the safety performance of the head-mounted device.

Further, in this embodiment, as shown in fig. 6, the first smoke exhaust section 221 further has a second passage port 2212 far away from the first passage port 2211, the fan 400 is provided with a smoke exhaust through hole 410 corresponding to the second passage port 2212, and the second smoke exhaust section 222 is communicated with the first smoke exhaust section 221 through the smoke exhaust through hole 410; a second sealing ring 600 is disposed between the bracket 300 and the fan 400, one side of the second sealing ring 600 surrounds the periphery of the second passage opening 2212, and the other side of the second sealing ring 600 surrounds the periphery of the smoke evacuation through hole 410. The second sealing ring 600 is arranged between the second passage port 2212 and the smoke exhaust through hole 410 to seal a gap between the second passage port 2212 and the smoke exhaust through hole 410, so that the smoke exhaust passage 220 can only exhaust smoke from the smoke exhaust port 210, and the safety performance of the head-mounted device is improved. Of course, in other embodiments, the fan 400 may be integrally formed with the bracket 300 to avoid a seam between the first smoke exhaust section 221 and the second smoke exhaust section 222, and also ensure the smoke exhaust effect of the smoke exhaust channel 220; the joint between the second passage opening 2212 and the smoke evacuation through hole 410 can also be sealed by gluing, so that a seam can be prevented from being generated between the first smoke evacuation section 221 and the second smoke evacuation section 222, and further, a thermosetting adhesive can be used for bonding, so that bonding failure caused by temperature rise in the smoke evacuation passage 220 when the battery 130 is burnt can be avoided; or, the fan is not provided with the smoke exhaust through hole, but the fan is internally provided with a second smoke exhaust section which is separately arranged, and the second smoke exhaust section is provided with the smoke exhaust through hole and is connected with the first smoke exhaust section through the smoke exhaust through hole.

Further, in this embodiment, as shown in fig. 6, the first smoke exhaust section 221 further has a second passage port 2212 far from the first passage port 2211, and the head-mounted device is further provided with a partition 800, wherein the partition 800 is located at a position capable of covering the second passage port 2212; the separator 800 can be moved away from covering the second opening 2212 when the battery is burned. Specifically, in this embodiment, the partition 800 is disposed on a side of the fan 400 away from the bracket 300 and covers the smoke evacuation through hole 410 to cover the second passage opening 2212, and the first smoke evacuation section 221 and the second smoke evacuation section 222 are not communicated with each other when the fan 400 performs heat dissipation and ventilation; when the battery 130 is burned, the separator 800 can be detached from the fan 400, so as to connect the first smoke evacuation section 221 to the second smoke evacuation section 222 when the fan 400 exhausts smoke.

It can be understood that other electronic devices (such as a motherboard) are further arranged in the head-mounted device, so that, in a normal use state of the head-mounted device, the fan 400 can dissipate and exhaust air, so that heat generated during operation of the electronic devices can be exhausted to the outside through hot air exhausted from the air outlet through the air outlet duct, and the partition 800 covers the smoke exhaust through hole 410 at this time, so that hot air generated by the fan 400 cannot be diffused to the first smoke exhaust section 221, and cannot enter the battery compartment 100, so that the working temperature of the battery 130 is prevented from being increased, and the working performance of the battery 130 is prevented from being affected; when the battery 130 burns, the pressure at two sides of the partition 800 is different due to the rise of the temperature of the battery compartment 100, specifically, the pressure at one side close to the first smoke exhaust section 221 is higher, and acts on the partition 800 to separate from the fan 400, so that the first smoke exhaust section 221 is communicated with the second smoke exhaust section 222, and under the action of the fan 400, smoke can be rapidly exhausted to the outside from the smoke exhaust port 210 through the smoke exhaust channel 220, so as to ensure the safety performance of the head-mounted display device.

In other embodiments without a fan, the partition 800 is directly disposed at a side of the bracket 300 close to the second passage 2212 and directly covers the second passage 2212, so that air in the external environment cannot enter the battery compartment 100 through the first smoke exhausting section 221 in a normal use state of the head-mounted device; when the battery is burned, the spacer 800 can be separated from the bracket 300, so as to conduct the first smoke exhaust section 221 with the external environment.

Further, the partition 800 is connected to a position capable of covering the second passage opening 2212 by means of bonding, specifically, in this embodiment, the partition 800 is bonded to the fan 400. Thus, when the battery 130 is burned, the smoke is discharged from the smoke outlet 120 to the first smoke discharge section 221, which causes the temperature in the first smoke discharge section 221 to increase, on the one hand, the viscosity of the adhesive between the spacer 800 and the fan 400 can be reduced, on the other hand, the pressure in the first smoke discharge section 221 can be increased, so as to break the adhesive relationship between the spacer 800 and the fan 400, so that the spacer 800 falls off from the fan 400, the first smoke discharge section 221 can be communicated with the second smoke discharge section 222, and thus the smoke can be discharged from the smoke outlet 210 to the outside. Of course, in other embodiments, the separator 800 may be a shape memory sheet inserted into the smoke evacuation through hole 410, and when the temperature rises to a certain level, the shape of the shape memory sheet can be changed, so as not to separate the first smoke evacuation section 221 from the second smoke evacuation section 222, that is, when the battery 130 is burned, the shape memory sheet can conduct the passage between the first smoke evacuation section 221 and the second smoke evacuation section 222.

Further, in this embodiment, the material of the isolation member 800 is a PET (Polyethylene terephthalate) material. The heat resistance of the spacer 800 made of the PET material is not high, the thermal deformation temperature is only about 85 ℃, and the spacer 800 can be ensured to lose efficacy in the process of burning the battery 130; in addition, the separator 800 made of PET has low gas permeability and excellent gas barrier performance, and can effectively prevent hot air from entering the first smoke exhaust section 221 when the fan 400 radiates and exhausts air, so as to affect the operation of the battery 130 in the battery compartment 100. Of course, in other embodiments, the spacer 800 may be made of PC (polycarbonate).

Further, in the present embodiment, as shown in fig. 2 to 4, the battery compartment 100 includes a compartment body 101 and a cover body 102, the compartment body 101 is of an open structure, the cover body 102 is disposed on the compartment body 101, and the smoke outlet 120 is disposed on the cover body 102. Without loss of generality, the cover body 102 is connected with the bin body 101 in a screw locking manner, so that the cover body 102 is detachably covered on the bin body 101. It can be understood that when the head-mounted device leaves the factory, the battery 130 may not be disposed inside the head-mounted device, and the battery 130 can be conveniently installed by the user due to the separated arrangement of the bin body 101 and the cover body 102. In addition, when other faults occur in the battery 130, the cover body 102 can be detached conveniently, and the battery 130 can be taken out, so that the battery 130 can be repaired or replaced. The lid 102 is provided with a smoke outlet 120, that is, the lid 102 is disposed closer to the bracket 300, and particularly, the width of the smoke outlet 120 on the lid 102 is less than 1mm, so as to meet the safety requirements, and in order to improve the smoke outlet efficiency of the smoke outlet 120, a plurality of smoke outlets 120 may be disposed on the lid 102. Since smoke may float upward, the smoke outlet 120 may be disposed in an upper region of the cover 102 to facilitate rapid discharge of smoke from the battery compartment 100.

Further, in this embodiment, the material of the bin body 101 and the cover 102 is fireproof, so as to prevent the battery 130 from affecting the battery bin 100 to burn when the battery 130 burns, which aggravates the fire. Furthermore, the bin body 101 and the cover 102 are made of V0 fireproof material, so that the flame retardance of the bin body is improved, and the safety performance of the head-mounted equipment is improved. Without loss of generality, the cover 102 is made of a metal material, which has flame retardancy, can improve the safety performance of the battery compartment 100, has a certain structural strength, can bear a certain external force, and can prevent the battery 130 in the compartment 101 from being squeezed.

Further, in the present embodiment, as shown in fig. 2, 4 and 7, a third sealing ring 700 is disposed at the connection between the cartridge body 101 and the cover 102. It can be understood that a gap is also generated at the joint of the bin body 101 and the cover body 102, and the third sealing ring 700 is used for sealing the joint therebetween, so as to ensure that the smoke in the battery compartment 100 is only discharged from the smoke outlet 120 on the cover body 102, and prevent the smoke from diffusing to other parts of the casing 200 through the gap at the joint of the cover body 102 and the bin body 101.

Optionally, in this embodiment, the first seal ring 500, the second seal ring 600, and the third seal ring 700 are all made of foam. The foam has the characteristics of elasticity, light weight, quick pressure-sensitive fixation, ultrathin volume, reliable performance and the like, and can play a good sealing role at seams of different structures in the head-mounted equipment. It should be noted that the foam material used as the first sealing ring 500, the second sealing ring 600, and the third sealing ring 700 should have flame retardancy to prevent the foam material from being burned by the combustion of the battery 130 to destroy the structure of the smoke evacuation channel 220, so as to ensure that the smoke evacuation channel 220 can exhaust smoke from the smoke evacuation port 210 to the outside.

Further, in this embodiment, as shown in fig. 1 and fig. 2, the casing 200 is formed with a wearing position 203, the smoke outlet 210 is disposed at an end of the casing 200 far away from the wearing position 203, and the air outlet duct extends in a direction far away from the wearing position 203. So, the exhaust smog can be towards the direction of keeping away from user's face in the exhaust hot-blast of air outlet duct or when battery 130 burns, avoids it to cause discomfort or cause the injury to user's face to further promote this head-mounted device's security performance.

The above description is only an alternative embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, which are within the spirit of the present invention, are included in the scope of the present invention.
