DETAILED DESCRIPTION
[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.
[0035] The present utility model embodiment provides an instrument 1000, such as Figure 1-Figure 4 As shown, the embodiment of the utility model provides an instrument 1000, such as Figure 1 As shown, the instrument 1000 includes a housing 100, and the housing 100 includes a face shell 110 and a back shell 120. The face shell 110 is the shell facing the user when the instrument 1000 is in use, and the back shell 120 is the shell facing away from the user when the instrument 1000 is in use. The back shell 120 is installed on the back of the face shell 110, and the face shell 110 and the back shell 120 jointly define an installation cavity 130. An anti-fog layer 200 is provided on the inner side of the face shell 110 facing the back shell 120, and a waterproof and breathable structure 300 is provided on the housing 100, so that the installation cavity 130 can be ventilated with the external space of the housing 100.
[0036] Specifically, the waterproof and breathable structure 300 not only allows the installation cavity 130 to exchange air with the external space, but also limits the water in the external space from flowing into the installation cavity 130, which is beneficial to limiting the formation of water mist inside the instrument 1000; in addition, the anti-fog layer 200 on the inner side surface can limit the formation of water mist on the inner side surface of the face shell 110; it can be seen that the waterproof and breathable structure 300 is used in combination with the anti-fog layer 200, so that the instrument 1000 provided in this embodiment has an excellent anti-fog effect, allowing the user to see the instrument 1000 clearly when the instrument 1000 is cold.
[0037] refer to Figure 2In one embodiment, a first groove 111 is provided on a side of the front shell 110 facing the back shell 120, and the back shell 120 and the first groove 111 jointly define a mounting cavity 130, the first groove 111 includes a groove bottom 112 and a groove wall 113, the groove wall 113 includes an adjacent area 1131 adjacent to the groove bottom 112, the spacing area is arranged on a side of the adjacent area 1131 away from the groove bottom 112, and the anti-fog layer 200 is arranged on the groove bottom 112 and the adjacent area 1131.
[0038] Specifically, since the user needs to observe the information displayed by the instrument 1000 through the face shell 110, and the groove bottom 112 is the position that needs to be seen through, the groove bottom 112 must be provided with an anti-fog layer 200. During actual production, the various regions cannot be perfectly divided, and the actual setting position of the anti-fog layer 200 may deviate slightly from the expected setting position. Therefore, if it is expected that the anti-fog layer 200 is only set at the groove bottom 112, in the actually processed product, the edge of the groove bottom 112 may not be set to the anti-fog layer 200 due to processing errors, and thus the anti-fog effect cannot be achieved. In order to solve this technical problem, the adjacent area 1131 where the groove wall 113 and the groove bottom 112 are adjacent is also provided with an anti-fog layer 200 in this embodiment, so that even if there is a processing error, it can be ensured that all positions of the groove bottom 112 are provided with an anti-fog layer 200.
[0039] In one embodiment, the anti-fog layer 200 is an inorganic semiconductor oxide layer to achieve excellent anti-fog effect. Further, a vacuum film can be used to attach the semiconductor oxide to the side of the front shell 110 facing the back shell 120 to form a semiconductor oxide layer. Optionally, the anti-fog layer 200 can also be made of aluminum hydroxide, siloxane, fluorocarbon polymer or other materials.
[0040] In a specific embodiment, the thickness of the anti-fog layer 200 is greater than or equal to 23 nm and less than or equal to 27 nm.
[0041] Specifically, compared to the embodiment in which the anti-fog layer 200 is only a few hundred nanometers thick, the anti-fog layer 200 of the present application is relatively thick, which can provide a more durable anti-fog effect. It is worth mentioning that, according to tests, the anti-fog layer 200 within this thickness range has little effect on transparency, so it will not affect the user's observation of the instrument 1000.
[0042] refer to Figure 4In one embodiment, a first hardness-enhancing layer 400 is provided between the face shell 110 and the anti-fog layer 200, and a second hardness-enhancing layer 500 is provided on the outer side of the face shell 110 facing away from the back shell 120. Specifically, if the face shell 110 is scratched, it will affect the user's observation of the instrument 1000. In order to increase the wear resistance of the face shell 110 and reduce the probability of the face shell 110 being scratched, the first hardness-enhancing layer 400 is provided between the face shell 110 and the anti-fog layer 200, and a second hardness-enhancing layer 500 is provided on the side of the face shell 110 facing the back shell 120. In this way, the face shell 110 will not be scratched so easily.
[0043] It should be noted that the reason why the first hardness enhanced layer 400 is arranged between the face shell 110 and the anti-fog layer 200 is that the anti-fog layer 200 needs to be exposed to the outside to achieve its anti-fog effect. If the anti-fog layer 200 is arranged between the first hardness enhanced layer 400 and the face shell 110, the anti-fog layer 200 will be obscured by the first hardness enhanced layer 400 and the anti-fog effect cannot be achieved.
[0044] In a specific embodiment, the first hardness reinforcement layer 400 and the second hardness reinforcement layer 500 are both silicone layers to achieve excellent wear resistance. Further, the first hardness reinforcement layer 400 and the second hardness reinforcement layer 500 are both attached to the side of the face shell 110 facing the back shell 120 by immersion. Optionally, the first hardness reinforcement layer 400 and the second hardness reinforcement layer 500 can also be made of transparent resin or other materials. In a specific embodiment, the thickness of the first hardness reinforcement layer 400 and the second hardness reinforcement layer 500 is greater than or equal to 3um, and less than or equal to 5um.
[0045] refer to Figure 5-Figure 8 In one embodiment, the waterproof breathable structure 300 includes an air hole 310 arranged on the housing 100, a waterproof breathable membrane 320 blocking the air hole 310, and a breathable cover 330 covering the air hole 310 away from the installation cavity 130. The breathable cover 330 is provided with a breathable structure 331 connecting the air hole 310 with the external space of the breathable cover 330, and the air inlet direction of the breathable structure 331 is set at an angle with the air inlet direction of the air hole 310.
[0046] First, by implementing this embodiment, the gas outside the instrument 1000 needs to first pass through the breathable structure 331 and then pass through the waterproof breathable membrane 320 before entering the housing 100. Because the air intake direction of the breathable structure 331 is set at an angle to the air intake direction of the air hole 310, the gas outside the instrument 1000 needs to change its flow path after entering the breathable cover 330 before passing through the waterproof breathable membrane 320, and cannot pass through the breathable cover 330 and the waterproof breathable membrane 320 in a straight line. Therefore, the instrument 1000 of this embodiment can effectively slow down the rate at which external moisture enters the interior when it is cold, thereby improving the amount and probability of fogging inside the instrument 1000, and effectively improving the anti-fogging effect of the instrument 1000.
[0047] Secondly, since the present embodiment provides a breathable cover 330 on the side of the breathable hole 310 away from the mounting cavity 130, when the instrument 1000 is impacted by water, the breathable cover 330 can provide certain protection for the waterproof breathable membrane 320, so that the waterproof breathable membrane 320 will not be directly impacted by water, thereby reducing the pressure on the waterproof breathable membrane 320 and ensuring that the waterproof breathable membrane 320 will not be damaged.
[0048] refer to Figure 6 , Figure 7 In a specific embodiment, the air permeable structure 331 includes a through hole 3311, and the angle between the axial direction of the through hole 3311 and the axial direction of the air permeable hole 310 is greater than or equal to 85°, and less than or equal to 95°. That is, the flow direction of the air when it passes through the through hole 3311 straightly and the flow direction of the air when it passes through the air permeable hole 310 straightly are greater than or equal to 85°, and less than or equal to 95°. In this way, after the external air enters the through hole 3311, the direction of travel must be greatly changed in order to pass through the waterproof breathable membrane 320. Compared with the embodiment in which the direction of travel is less changed, this embodiment can effectively slow down the rate at which humid air enters the interior of the housing 100.
[0049] Exemplarily, the axial angle between the through hole 3311 and the air vent 310 is 90°. Optionally, the axial angle between the through hole 3311 and the air vent 310 can also be 85°, 95° or other angles greater than 85° and less than 95°.
[0050] refer to Figure 6 , Figure 7In another embodiment, a boss 150 is provided on the outer surface 140 of the housing 100, the vent hole 310 is provided on the end wall 151 of the boss 150, and the vent cover 330 is sleeved on the boss 150; the outer surface 140 of the housing 100 includes an adjacent portion 141 arranged around the boss 150, and a support block 332 is provided on the side of the vent cover 330 facing the end wall 151, and the support block 332 and the end wall 151 of the boss 150 are connected. Partially abutting so that the breathable cover 330 is spaced apart from the adjacent portion 141, the breathable structure 331 includes a second groove 3312 arranged on the side of the peripheral wall of the breathable cover 330 facing the boss 150, the second groove 3312 extends in the axial direction of the breathable hole 310, one end of the second groove 3312 is connected to the side of the breathable cover 330 close to the adjacent portion 141, and the other end is connected to the area of the end wall 151 facing away from the adjacent portion 141.
[0051] By implementing this embodiment, outside air can enter the breathable cover 330 from the second groove 3312, and the flow direction of the air in the second groove 3312 and the flow direction in the breathable hole 310 are at a large angle, so that the direction of the outside air after entering the second groove 3312 must be greatly changed to pass through the waterproof breathable membrane 320, so the implementation of this embodiment can effectively slow down the rate at which humid air enters the interior of the housing 100. When the instrument 1000 is impacted by water, the pressure on the waterproof breathable membrane 320 will also be relatively small.
[0052] refer to Figure 6 , Figure 7 In another specific embodiment, the air-permeable structure 331 includes the through hole 3311 and the second groove 3312 shown in the above two embodiments.
[0053] refer to Figure 9-12 In one embodiment, a first flow limiting block 311 is provided on the hole wall of the air vent 310 .
[0054] On the one hand, the first flow limiting block 311 will limit the flow rate of air in the air vent 310 to a certain extent, so providing the first flow limiting block 311 can further slow down the rate at which humid air enters the interior of the housing 100 .
[0055] Secondly, when the instrument 1000 is impacted by water, the first flow limiting block 311 will limit the flow rate of water in the air hole 310 to a certain extent, so the first flow limiting block 311 can provide a certain protection for the waterproof breathable membrane 320, reduce the pressure on the waterproof breathable membrane 320, and ensure that the waterproof breathable membrane 320 will not be damaged.
[0056] refer to Figure 9-12In a specific embodiment, a second flow limiting block 312 is provided on the hole wall of the air vent 310 , and the second flow limiting block 312 and the first flow limiting block 311 are spaced apart in the axial direction and radial direction of the air vent 310 .
[0057] In this embodiment, a second flow-limiting block 312 is added on the basis of the first flow-limiting block 311, and the first flow-limiting block 311 and the second flow-limiting block 312 are arranged at intervals in the axial direction and radial direction of the air vent 310. Therefore, compared with the embodiment in which only the first flow-limiting block 311 is provided, the cooperation of the first flow-limiting block 311 and the second flow-limiting block 312 in this embodiment can further limit the flow of air in the air vent 310, thereby further reducing the rate at which humid air enters the interior of the housing 100. Similarly, when the instrument 1000 is impacted by water, the cooperation of the first flow-limiting block 311 and the second flow-limiting block 312 can also further limit the flow rate of water in the air vent 310, thereby providing stronger protection for the waterproof breathable membrane 320.
[0058] refer to Fig.13 In one embodiment, the back shell 120 and the face shell 110 are locked together by screws, and a mounting groove 121 is provided on the side of the back shell 120 close to the face shell 110, and an edge 114 of the face shell 110 close to the back shell 120 is embedded in the mounting groove 121, and a sealing ring 600 is sandwiched between the edge 114 and the bottom of the mounting groove 121 to ensure that the installation cavity 130 can only be ventilated with the external space through the waterproof and breathable structure 300, thereby reducing the probability of fogging inside the instrument 1000.
[0059] The utility model also provides a means of transportation, such as Figure 1-Figure 4 As shown, the vehicle includes the instrument 1000 shown in the above embodiment. The beneficial effects of the instrument 1000 have been recorded in the above embodiment, so this application will not repeat them here.
[0060] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
