Description

Technical Field

[0001] The utility model relates to the technical field of display devices, and more particularly, to a display. Background Art

[0002] In the related art, a display usually relies on its housing structure to prevent water from entering its interior and affecting its normal operation. However, in practice, it is difficult to make the display housing completely airtight. Due to requirements such as assembly, heat dissipation, and external sound, there are usually openings on the display housing. When used in certain environments, external water can easily enter the interior of the display through the openings on the housing.

[0003] For example, when a medical display is used in clinical and surgical operations to show patient information to doctors or provide image support such as surgical navigation, when external liquid spills or splashes onto the display, it can easily enter the interior through the openings on the display housing, thereby leading to sudden situations such as display failures.

[0004] It can be seen that the displays in the related art have the technical problem of being prone to failures due to water ingress. To address this technical problem, no effective solution has been proposed yet.

[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the drawings are used to distinguish different objects, rather than to limit a specific order. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0033] Please refer to Figures 1 to 8, the display of the embodiment of the present utility model includes: a display housing 1, with an opening 11 provided on the display housing 1; a protection component 2, the protection component 2 is arranged inside the display housing 1, and a diversion structure 20 is provided inside or on the surface of the protection component 2; wherein, the position of the protection component 2 corresponds to the position of the opening 11, and the water entering the inside of the display housing 1 through the opening 11 falls onto the protection component 2 under the action of gravity and flows along the diversion structure 20 to the target position.

[0034] For the display designed with this structure, during actual use, when the water outside the display flows into the inside of the display housing 1 through the opening 11, since the position of the protection component 2 corresponds to the opening 11, the water will fall on the protection component 2 and flow along the diversion structure 20 to the target position. By designing the protection component 2 and the diversion structure 20 thereon, the water flowing into the display can be diverted to the target position, thereby preventing the water from flowing to the positions of some components that are prone to failure when encountering water inside the display, ensuring the normal operation of the display, improving the safety and reliability of the display during use, and solving the technical problem that the display in the related art is prone to failure due to water ingress.

[0035] During specific implementation, the above-mentioned target position can be any position, as long as the normal operation of the display is not affected after the water is diverted to this target position. For example, it can be a water storage structure arranged inside the display, or it can be a drain port communicating with the external space of the display housing 1, so that the water can be discharged to the outside of the display through it.

[0036] During actual implementation, the opening 11 can be various forms of openings on the display housing 1. For example, it can be some gaps on the display housing 1, a heat dissipation port designed to enhance heat dissipation, a sound outlet designed to play sound, a connection port designed for operations such as wiring, etc., as long as the opening 11 connects the inside and outside of the display housing 1 and there is a risk of water ingress through the opening 11.

[0037] During specific implementation, the diversion structure 20 can have multiple structural form options. Specifically, the diversion structure 20 can be a protrusion provided on the surface of the protection component 2, or the diversion structure 20 is a depression provided on the surface of the protection component 2, or the diversion structure 20 is a diversion channel provided inside the protection component 2.

[0038] For example, in an alternative embodiment, the diversion structure 20 is a strip-shaped protrusion designed on the surface of the protective component 2, and the strip-shaped protrusion extends towards the above-mentioned target position, so that water can flow along the strip-shaped protrusion to the target position. For another example, in another alternative embodiment, the diversion structure 20 is a recessed structure designed on the surface of the protective component 2. Specifically, it is a strip-shaped groove structure, and water can flow along the strip-shaped groove structure to the above-mentioned target position. For another example, in another alternative embodiment, the diversion structure 20 is a diversion channel designed inside the protective component 2, such as a diversion pipe, and water can flow along the diversion channel to the above-mentioned target position.

[0039] In this embodiment, as Figure 5 shown, the diversion structure 20 includes: a main trunk and a plurality of branch trunks. The plurality of branch trunks are all connected to the main trunk. The branch trunks are located on the side of the main trunk close to the opening 11. The water entering the inside of the display housing 1 through the opening 11 is collected by the branch trunks and converges to the main trunk, and flows to the target position through the main trunk.

[0040] By designing a plurality of branch trunks connected to the main trunk, the water scattered at different positions on the protective component 2 can be collected and converged to the main trunk through the plurality of branch trunks, and flow along the main trunk to the target position, which is beneficial to drain the scattered water more timely, and reduce the risk that the water flows to other positions and affects the operation of the display due to untimely drainage.

[0041] Specifically, when the display is placed at the working angle, the branch trunks are arranged obliquely to the horizontal direction, and / or there are a plurality of diversion structures 20, and the plurality of diversion structures 20 are arranged at intervals.

[0042] By arranging each branch trunk obliquely to the horizontal direction, the water can converge better to the main trunk under the action of gravity. It is easy to understand that in order to enable the converged water to flow smoothly to the target position, at least part of the main trunk needs to extend towards the target position. As a preferred embodiment, when the display is placed at the working angle, at least part of the main trunk is inclined to the horizontal direction or perpendicular to the horizontal direction, so that along the direction close to the target position, the height of the main trunk decreases, ensuring that the water can flow along the main trunk to the target position under the action of gravity. By designing a plurality of diversion structures 20, the diversion ability of water can be improved, which is beneficial to drain the water to the above-mentioned target position more quickly.

[0043] As Figure 2As shown, in this embodiment, the display includes an electrical component 100 disposed within a display housing 1. The protective component 2 includes: a first protective member 21 disposed between the main body portion of the electrical component 100 and an opening 11, with an avoidance opening provided on the first protective member 21; and a second protective member 22 cooperating with the first protective member 21 and covering the avoidance opening. The diversion structure 20 includes: a first diversion section 201 disposed on the first protective member 21; and a second diversion section 202 disposed on the second protective member 22. Wherein, the first diversion section 201 and the second diversion section 202 are spliced and cooperate, and water entering the interior of the display housing 1 through the opening 11 flows to the first diversion section 201 through the second diversion section 202.

[0044] In actual implementation, the electrical component 100 can be any electrical component. Electrical components are prone to malfunctions after coming into contact with water, so the protective component 2 is needed to protect it. In this embodiment, the electrical component 100 includes a circuit board and electrical components mounted thereon. As the name implies, both the first protective member 21 and the second protective member 22 are components for protecting the electrical component 100. Specifically, the main body portion of the electrical component 100 and the opening 11 are respectively disposed on opposite sides of the first protective member 21, so that the two are separated by the first protective member 21. Therefore, the first protective member 21 can protect the main body portion of the electrical component 100, preventing water or dust entering the display housing 1 through the opening 11 from reaching the electrical component 100 and affecting the normal operation of the electrical component 100. However, in this embodiment, the first protective member 21 does not completely isolate the electrical component 100 from the opening, but rather a avoidance opening is designed on the first protective member 21 (i.e., Figure 2 the opening shown at the central position of the first protective member 21 through which a part of the electrical component 100 is exposed). In actual implementation, some components of the electrical component 100 can pass through this avoidance opening to reach the other side of the first protective member 21, or the electrical component 100 can be entirely located on the side of the first protective member 21 away from the opening 11. By providing the avoidance opening, it is beneficial to expose a part of the electrical component 100, facilitating operations such as wiring and maintenance. On the basis of designing the above-mentioned avoidance opening, the protective component 2 of the display in this embodiment further includes a second protective member 22 that covers the avoidance opening.

[0045] The first diversion section 201 and the second diversion section 202 mentioned herein are spliced and matched, which should be understood as long as water can flow smoothly along the second diversion section 202 to the first diversion section 201. In actual implementation, the two can be assembled and contacted together, or can be spaced apart by a certain distance (for example, there is a certain drop between the upper and lower). That is to say, the first diversion section 201 and the second diversion section 202 do not have to be in contact with each other.

[0046] In an alternative embodiment, as Figure 5 and Figure 6 shown, a water storage cavity 12 is provided inside the display housing 1, the target position is the water storage cavity 12, and the water storage cavity 12 has one or more water inlets 121. Along the direction close to the inside of the water storage cavity 12, the diameter of the water inlet 121 gradually decreases.

[0047] The water inlet 121 is the channel for the water flowing down from the diversion structure 20 to enter the water storage cavity 12, and the water inlet 121 connects the inside and outside of the water storage cavity 12. In this embodiment, along the direction towards the inside of the water storage cavity 12, the diameter of the water inlet 121 gradually decreases. That is to say, the closer to the water storage cavity 12, the smaller the diameter of the water inlet 121. Of course, the opening shape of the water inlet 121 is not limited to a circle, and correspondingly, its diameter does not only refer to the diameter. It should be understood as the area of the flow cross-section of the water inlet 121, that is, along the direction towards the inside of the water storage cavity 12, the area of the flow cross-section of the water inlet 121 gradually decreases. With this structural design, when water enters the water storage cavity 12, there is a larger inlet, and since the diameter of the position where the water inlet 121 communicates with the water storage cavity 12 is smaller, even if the water in the water storage cavity 12 shakes, it is difficult to flow out of the water storage cavity 12, thereby avoiding the situation that the collected water flows out again and affects the normal operation of the internal components of the display.

[0048] As Figure 6 shown, in this embodiment, a water collecting tank 13 is provided inside the display housing 1, the water inlet 121 is arranged at the bottom of the water collecting tank 13, and along the direction close to the water inlet 121, the cross-sectional area of the water collecting tank 13 gradually decreases; and / or, the display includes a liquid level detection component 15, and the liquid level detection component 15 detects the liquid level in the water storage cavity 12.

[0049] The liquid level detection component 15 detects the liquid level in the water storage cavity 12, so as to facilitate the user to better understand the water accumulation situation in the water storage cavity 12 and drain the water in time, which can avoid the situation that the internal components of the display are damaged due to water overflow in the water storage cavity 12. Specifically, its specific structural form can be flexibly selected according to actual needs. For example, in a specific embodiment, the liquid level detection component 15 is a liquid level sensor, which is fixedly arranged at a preset height position of the display housing 1 and is equipped with an indicator light. When the liquid level reaches this preset height, it is detected by the liquid level sensor, and then the indicator light of the liquid level sensor lights up to prompt the user to drain the water in the water storage cavity 12.

[0050] Preferably, the display further includes a fog blocking component 14, which is arranged in the water storage cavity 12 and corresponds to the position of the water inlet 121. The fog blocking component 14 blocks the water vapor and / or water mist generated in the water storage cavity 12 from flowing out of the water storage cavity 12 through the water inlet 121.

[0051] By designing the fog blocking component 14 at the position corresponding to the water inlet 121 in the water storage cavity 12, it can block the water vapor or water mist generated in the water storage cavity 12 and prevent it from further returning to the main space of the display housing 1 through the water inlet 121, thereby reducing the influence of water mist or water vapor on the components in the display.

[0052] When the display is placed at a working angle, at least a part of the fog blocking component 14 is arranged obliquely to the horizontal direction; or, along the direction from the center of the fog blocking component 14 to the edge of the fog blocking component 14, the fog blocking component 14 is bent towards the side away from the water inlet 121.

[0053] In a class of alternative embodiments, when the display is placed at a working angle, at least a part of the fog blocking component 14 is inclined to the horizontal direction. For example, the fog blocking component 14 is a baffle structure arranged obliquely, so that the water flowing from the water inlet 121 to the fog blocking component 14 can flow down along the inclined surface under the action of gravity.

[0054] In another class of alternative embodiments, along the direction from the center of the fog blocking component 14 to the edge of the fog blocking component 14, the fog blocking component 14 is bent towards the side away from the water inlet. That is to say, the fog blocking component 14 is a bent structure, and along the direction from the center to the periphery, the fog blocking component 14 is bent towards the side away from the water inlet 121. That is, the closer to the center of the fog blocking component 14, the closer the fog blocking component 14 is to the water inlet 121. For example, in a preferred embodiment, the fog blocking component 14 is an umbrella-shaped structure. Using this structural design can not only make the water flowing from the water inlet 121 to the fog blocking component 14 flow down along the inclined surface under the action of gravity, but also the fog blocking component 14 covers the water in the water storage cavity 12 in a cover shape, which is beneficial to further reducing the outflow of water vapor through the water inlet 121.

[0055] In an alternative embodiment, a water storage cavity 12 is provided inside the display housing 1, and the target position is the water storage cavity 12, where: the display includes a heat dissipation pipeline 16, and the heat dissipation pipeline 16 is communicated with the water storage cavity 12, wherein at least a part of the heat dissipation pipeline 16 extends towards the electrical components 100 inside the display housing 1; and / or, a drain port 17 is provided on the display housing 1, the drain port 17 communicates the inside and outside of the water storage cavity 12, and the display further includes a drain switch 18, and at least a part of the drain switch 18 is movably provided to block or conduct the drain port 17.

[0056] By designing the heat dissipation pipeline 16 communicated with the water storage cavity 12, the water collected in the water storage cavity 12 can flow through the heat dissipation pipeline 16 to a position closer to the electrical components 100, thereby improving the heat dissipation effect on the electrical components 100. Preferably, when the display is placed at the working angle, along the direction close to the electrical components 100, the height of the heat dissipation pipeline 16 gradually increases. In this way, when draining the water in the water storage cavity 12, the water in the heat dissipation pipeline 16 can be more easily drained. In this embodiment, there are two water storage cavities 12, and the two water storage cavities 12 are correspondingly arranged on the opposite sides of the display, and the heat dissipation pipeline 16 communicates the two water storage cavities 12.

[0057] In this embodiment, a drain cavity 19 is further provided inside the display housing 1. When the display is placed at the working angle, the drain cavity 19 is located below the water storage cavity 12. When the drain switch 18 makes the drain port 17 conductive, the water in the water storage cavity 12 flows into the drain cavity 19 under the action of gravity. A plurality of water outlet holes 191 are provided on the display housing 1, and the water outlet holes 191 communicate the drain cavity 19 with the outside of the display housing 1, so that the water in the drain cavity 19 flows out to the outside of the display through the water outlet holes 191. In a preferred embodiment, the water storage cavity 12, the water collecting groove 13, the anti-fog member 14, the drain port 17, the drain switch 18, the drain cavity 19, the water outlet holes 191, etc. are all structures provided on the middle frame 101.

[0058] In actual implementation, the specific structural form of the display housing 1 can be various as long as it can play a role in protecting the internal components. In this embodiment, the display housing 1 includes a middle frame 101, a front panel 102 and a rear shell 103. The front panel 102 and the rear shell 103 are correspondingly assembled on both sides of the middle frame 101, so that the internal space of the display housing 1 is jointly enclosed by the three. That is to say, the middle frame 101 is a structure with openings on both sides. One side of it cooperates with the front panel 102 to achieve sealing, and the other side cooperates with the rear shell 103 to achieve sealing.

[0059] Such as Figure 6As shown in the figure, an embodiment of the display of the present utility model includes: a display housing 1 and a water storage cavity 12. The water storage cavity 12 is arranged inside the display housing 1, and the water storage cavity 12 stores the water entering the display housing 1; a fog blocking member 14, the fog blocking member 14 corresponding to the position of the water inlet 121 of the water storage cavity 12, and the fog blocking member 14 blocks the water vapor and / or water mist generated in the water storage cavity 12 from flowing out of the water storage cavity 12 through the water inlet 121.

[0060] In this embodiment of the display, by designing the water storage cavity 12 inside the display housing 1, when external water enters the display, it can flow into the water storage cavity 12 for unified storage. On this basis, a fog blocking member 14 is designed at the position corresponding to the water inlet 121 in the water storage cavity 12, which can block the water vapor or water mist generated in the water storage cavity 12 and prevent it from further returning to the main space of the display housing 1 through the water inlet 121. By adopting this structural design, the water entering the display can be effectively collected, and the influence of water mist or water vapor on the components inside the display can be reduced, thereby improving the use stability of the display and solving the technical problem that the display in the related art is prone to failure due to water ingress.

[0061] In a preferred embodiment, along the direction from the center of the fog blocking member 14 to the edge of the fog blocking member 14, the fog blocking member 14 is bent and arranged toward the side away from the water inlet 121. That is to say, the fog blocking member 14 is in an umbrella shape to cover the water in the water storage cavity 12. By adopting this structural design, not only can the water flowing from the water inlet 121 to the fog blocking member 14 flow down along the inclined surface under the action of gravity, but also the fog blocking member 14 is in a cover shape to cover the water in the water storage cavity 12, which is beneficial to further reducing the outflow of water vapor through the water inlet 121. Along the direction close to the inside of the water storage cavity 12, the caliber of the water inlet 121 gradually decreases, so that on the basis of ensuring that water can flow smoothly into the water storage cavity 12, the risk of the water or water vapor in the water storage cavity 12 flowing out to the outside through the water inlet 121 can be further reduced.

[0062] In a preferred embodiment, in order to improve the waterproof sealing effect of the display housing 1, the front panel 102 is fitted and cooperated with the middle frame 101, so as to form a first waterproof layer at the position where the two are in close contact. The display further includes a first sealing structure 31, and the first sealing structure 31 is arranged between the front panel 102 and the middle frame 101, so as to fill and seal the gap therebetween. Specifically, the first sealing structure 31 includes a panel fixing adhesive 311, and the panel fixing adhesive 311 is pasted on the side of the front panel 102 close to the middle frame 101, so as to bond and fix the front panel 102 and the middle frame 101 together through the panel fixing adhesive 311. The first sealing structure 31 further includes a waterproof foam 312, and the waterproof foam 312 fills and seals the gap between the side surface of the front panel 102 and the middle frame 101. In this way, the panel fixing adhesive 311 and the waterproof foam 312 can jointly form a second waterproof layer, further improving the waterproof sealing effect between the front panel 102 and the middle frame 101. Through the first waterproof layer and the second waterproof layer, the risk of water entering the display can be effectively reduced. For the rear case 103, after it is assembled to the middle frame 101, the two are in close fit with each other to form a third waterproof layer. The display further includes a second sealing structure 32, and the second sealing structure 32 is arranged between the protective component 2 (the first protective component 21 in this embodiment) and the rear case 103, so as to fill and seal the gap therebetween to form a fourth waterproof layer. In this way, through the third waterproof layer and the fourth waterproof layer, the waterproof performance at the rear side of the display can be effectively improved. Even in the case of a large amount of liquid splashing, it is difficult for the liquid to enter the position of the components inside the display, thereby effectively improving the safety and reliability of the display during use.

[0063] In this embodiment, the display includes a display screen 4, which is arranged inside the display housing 1 and located between the front panel 102 and the first protective component 21, so as to protect its screen through the front panel 102 and perform mechanical protection and waterproofing on its back through the first protective component 21.
