Description
Technical Field
[0001] The invention relates to the technical field of heat dissipation structures, and in particular to a heat dissipation device for an intelligent gateway. Background Art
[0002] An intelligent gateway is a hardware or virtual device that integrates network equipment and software functions with a heat dissipation device. It can achieve device interconnection and data interaction through various communication protocols. It has been used in many scenarios such as smart homes, industrial manufacturing, healthcare, transportation, and urban management. As a key node in the Internet of Things system, the intelligent gateway needs to process a large amount of data and communicate in real time. During this process, a large amount of heat will be generated inside the device. If the heat dissipation is poor, the temperature of the device will rise, which will affect its performance and stability, and even cause failures.
[0003] The device shell of the smart gateway is usually provided with heat dissipation holes, which are connected to the inside and can achieve the effect of cooling and heat dissipation with the help of a cooling fan. However, the heat dissipation holes are always in an open state. If the smart gateway is not in use and is directly placed outside and exposed to the outside, dust may enter the device inside the smart gateway through the heat dissipation holes, which may affect the subsequent use of the smart gateway. In addition, the placement status of the smart gateway may be different in different scenarios. During the use of the smart gateway, it is necessary to ensure that the heat dissipation holes are in an open state, otherwise the heat dissipation effect may be affected, resulting in the failure to achieve the desired heat dissipation effect, and the heat in the device cannot be discharged in time. In the design of the heat dissipation holes, the heat dissipation hole status needs to be adjusted according to different placement states to increase the practicality of the device.

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0022] Example: Figure 1-Figure 12As shown, a heat dissipation device for an intelligent gateway according to the present invention comprises a box body 1 and a mounting seat 2, the bottom of the box body 1 is fixedly connected to the top of the mounting seat 2, movable bins 11 are arranged at both ends of the box body 1, and an adjustment mechanism 4 is arranged in the movable bin 11, the adjustment mechanism 4 comprises a support column 45 slidably connected to the bottom of the box body 1, a fan 3 is arranged at the bottom of the box body 1, a guide air duct 31 is fixedly connected to the bottom of the fan 3, and a steering mechanism 5 is fixedly connected to both ends of the mounting seat 2; the adjustment mechanism 4 is assembled so that the box body 1 and the mounting seat 2 are in a heavy position when placed flat. The movable mesh plate 41 is moved downward under the action of the force, so that the movable mesh plate 41 movably connected to the inner wall of the box body 1 moves upward, thereby overlapping with the heat dissipation holes 12 opened on the side wall of the box body 1; the steering mechanism 5 is equipped so that when the box body 1 is turned over and hung, the movable mesh plate 41 can move along a moving trajectory different from that when it is laid flat, overlap with the heat dissipation holes 12 again, and reset the movable mesh plate 41 when it is removed; the limiting mechanism 6 is equipped so that when the steering mechanism 5 is working, it can limit the support column 45 to ensure the stability of the movement of the movable mesh plate 41.
[0023] In this embodiment, when the device is laid flat, the box body 1 and the mounting seat 2 connected together move downward under the action of gravity, the spring 43 is compressed, the top of the fixed protrusion 47 is in contact with the top of the first movable groove 46, and the fixed protrusion 47 supports the movable mesh plate 41 to remain stationary. Therefore, when the box body 1 moves downward, the second movable groove 49 moves downward at the same time, and the first sliders 411 on both sides of the movable mesh plate 41 gradually come to the vertical groove section of the second movable groove 49. The mesh of the movable mesh plate 41 begins to overlap with the heat dissipation holes 12 on the box body 1. When the fan 3 is working, it can accelerate the air flow in the movable bin 11 and discharge the heat in the movable bin 11 from the guide duct 31. When the device needs to be flipped 90 degrees for hanging, the support column 45 is rotated to make the second slider 62 slide in the horizontal groove section of the L-shaped slide groove 61. During the rotation of the support column 45, the fixed protrusion 47 always clamps the first fixed plate 48 to limit the moving direction of the movable mesh plate 41. When hanging, the movable block 54 is squeezed and slides, pushing the movable mesh plate 41 to move upward, so that the mesh holes of the movable mesh plate 41 overlap with the heat dissipation holes 12 again. When the smart gateway is not in use, the heat dissipation holes 12 can be closed to reduce the entry of dust. When in use, the heat dissipation holes 12 can be opened in both flat and suspended conditions to enhance the heat dissipation effect.
[0024] like Figure 3-Figure 7As shown, the adjustment mechanism 4 also includes a first slide groove 42 opened at the bottom of the box body 1, a spring 43 is fixedly connected to the top of the first slide groove 42, and a fixed block 44 is fixedly connected to the end of the spring 43 away from the top of the first slide groove 42, and the fixed block 44 is rotatably connected to the support seat.

[0025] In this embodiment, in the initial state, the mesh of the movable mesh plate 41 does not overlap with the heat dissipation hole 12, and the heat dissipation hole 12 is in a closed state, which can reduce the entry of dust when the device is not in use. The first slider 411 is located at the corner of the second movable groove 49 in the current state. When it is used flat, the fan 3 is turned on, the box body 1 and the mounting seat 2 move downward under their own gravity, the spring 43 is compressed, the distance between the top of the support column 45 and the top of the first slide groove 42 is reduced, the fixed protrusion 47 approaches the top of the first movable groove 46, and the first fixed plate 48 clamped by the fixed protrusion 47 is restricted, so that the movable The first sliders 411 at both ends of the movable mesh plate 41 slide in the vertical grooves of the second movable grooves 49 in the current state, and the mesh holes of the movable mesh plate 41 coincide with the heat dissipation holes 12. When the second connecting plate 59 is fixed, the second fixed plate 512 at the bottom of the movable mesh plate 41 always slides in the two second connecting plates 59. When the fan 3 is in operation, it can accelerate the air flow in the movable bin 11, bring the air outside the equipment into the equipment, and then discharge the air in the movable bin 11 out of the equipment from the guide air duct 31, and discharge the heat from the guide air duct 31, so as to realize the circulation of air and achieve the effect of heat dissipation and cooling.
[0026] like Figure 6-Figure 12As shown, the steering mechanism 5 includes a connecting block 51 fixedly connected to both ends of the mounting seat 2, the connecting block 51 is provided with a slot 52 and a mounting slot 57, the mounting slots 57 are symmetrically arranged on both sides of the slot 52, a first connecting slot 53 is provided at one end of the slot 52, and limiting slots 55 are provided at both sides of the slot 52, a movable block 54 is slidably connected in the slot 52, a first connecting plate 56 is fixedly connected to both sides of one end of the movable block 54, the first connecting plate 56 is slidably connected to the limiting slot 55, an elastic telescopic rod 58 is fixedly connected to one end of the mounting slot 57, and the end of the elastic telescopic rod 58 away from the side wall of the mounting slot 57 is fixedly connected to the first connecting plate 56; the movable mesh plate 4 A second fixing plate 512 is fixedly connected to the bottom of the mounting seat 2, second slide grooves 511 are provided at both ends of the mounting seat 2, the second fixing plate 512 is slidably connected to the second slide grooves 511, a second connecting groove 510 is provided on the side of the mounting groove 57 close to the box body 1, the second connecting groove 510 cooperates with the second slide groove 511, a group of second connecting plates 59 is fixedly connected to the side of the first connecting plate 56 close to the box body 1 away from the movable block 54, the second connecting plate 59 abuts against the second fixing plate 512 and is vertically arranged, and the second fixing plate 512 is located between the two second connecting plates 59; the heat dissipation holes 12 are arranged in parallel, and the meshes of the movable mesh plate 41 are arranged in a staggered manner.
[0027] In this embodiment, when the device needs to be hung for use, the support columns 45 are rotated respectively first, so that the second slider 62 on each support column 45 enters the horizontal groove of the L-shaped slide groove 61 in the current state, so that the connection between the support column 45 and the box body 1 is restricted and fixed, and the fixed block 44 rotatably connected to the support column 45 remains motionless under the restriction of the third slider 64 and the straight groove 63. The device is flipped 90 degrees, and the screws fixed to the wall pass through the slots 52 on the connecting block 51. Under the action of gravity, the movable block 54 is squeezed and slides upward, so that the elastic telescopic rods 58 on both sides of the movable block 54 are stretched, and the second connecting plate 59 fixedly connected to the first connecting plate 56 moves up, so that the second connecting plate 59 connected to the second connecting plate 56 is fixedly connected to the second connecting plate 56. The second fixed plate 512 clamped by the connecting plate 59 moves up, and the first fixed plates 48 at both ends of the movable mesh plate 41 slide in the two fixed protrusions 47 while being clamped by the fixed protrusions 47, and the first slider 411 slides in the vertical groove of the second movable groove 49 in the current state, so that the movable mesh plate 41 moves with a moving trajectory different from that when it is laid flat, and the mesh holes on the movable mesh plate 41 coincide with the heat dissipation holes 12 again. When the device is removed, the elastic telescopic rod 58 pulls the movable block 54 to reset, so that the movable mesh plate 41 returns to the initial position, and the heat dissipation holes 12 are closed again. When it continues to be used, the state of the heat dissipation holes 12 can still be automatically adjusted according to the placement state of the use scenario, thereby increasing the flexibility of the device.
[0028] In this embodiment, if Figure 1-Figure 3As shown, the mesh holes on the movable mesh plate 41 are staggered, and when the box body 1 moves in two directions respectively, the movable mesh plate 41 can overlap with the heat dissipation holes 12, and the mesh holes of the movable mesh plate 41 that overlap with the heat dissipation holes 12 are different when used horizontally and when used suspended. In the initial state, the mesh holes of the movable mesh plate 41 do not overlap with the heat dissipation holes 12. In different usage states, in the connection between the movable mesh plate 41 and the box body 1, the first fixed plates 48 on both sides of the movable mesh plate 41 are always clamped by the two fixed protrusions 47, and at the same time, the second fixed plate 512 at the bottom of the movable mesh plate 41 is always clamped by the two second connecting plates 59, and the connection relationship is maintained when the movable mesh plate 41 moves, and it will not be separated from the fixed protrusions 47 and the second connecting plates 59.
[0029] like Figure 4 and Figure 5 As shown, the limiting mechanism 6 includes an L-shaped slide groove 61 opened on the side wall of the first slide groove 42, a group of second sliders 62 are fixedly connected to the outer wall of the support column 45, the second slider 62 is slidably connected to the L-shaped slide groove 61, a straight groove 63 is opened on the top of the L-shaped groove, and a group of third sliders 64 are fixedly connected to the outer wall of the fixed block 44, and the third slider 64 is slidably connected to the straight groove 63.
[0030] In this embodiment, when not in use or when it needs to be hung for use, the support column 45 can be rotated so that the second slider 62 slides in the horizontal groove of the L-shaped slide groove 61, thereby preventing the box body 1 and the support column 45 from sliding, restricting the movable mesh plate 41, and enhancing its stability. When the support column 45 rotates, the fixed block 44 remains stationary.
[0031] Working principle: when the box body 1 is used horizontally, the fan 3 is turned on, and the four support columns 45 support the box body 1. The box body 1 and the mounting seat 2 move downward under the action of their own gravity, so that the spring 43 is compressed, and the distance between the top of the support column 45 and the first slide groove 42 is reduced. The fixed protrusions 47 fixedly connected to the support columns 45 clamp the first fixed plates 48 on both sides of the movable mesh plate 41, so that the horizontal position of the movable mesh plate 41 remains stationary. Therefore, when the box body 1 moves downward, the box body 1 and the movable mesh plate 41 slide, and the second movable groove 49 fixedly connected to the box body 1 moves downward, so that the first slider 411 enters the vertical groove of the second movable groove 49, and the heat dissipation holes 12 on the box body 1 coincide with the mesh holes on the movable mesh plate 41, so that the heat dissipation holes 12 are opened. When the fan 3 is in operation, the air in the movable bin 11 can be accelerated to circulate, thereby increasing the heat dissipation effect. When the box is suspended for use, the fan 3 is turned on. Compared with the flat use, the box body 1 is flipped 90 degrees, the movable block 54 is squeezed and moved upward, close to the first connecting groove 53, and the first connecting plate 56 slides in the installation groove 57, so that the second connecting plate 59 fixedly connected to the first connecting plate 56 clamps the second fixing plate 512 at the bottom of the movable mesh plate 41 to move, so that the mesh on the movable mesh plate 41 overlaps with the heat dissipation hole 12 again. When the box is suspended for use, the support column 45 can be rotated first so that the second slider 62 on the support column 45 enters the L-shaped slide groove 61. In the horizontal groove, the position of the box body 1 and the support column 45 is fixed to prevent the support column 45 from being squeezed during suspension, resulting in a lack of stability of the box body 1. During the rotation of the support column 45, the fixed block 44 is rotatably connected to the support column 45, and the fixed block 44 is not affected by the rotation of the support column 45. After the device is removed, the elastic telescopic rod 58 pulls the movable block 54 to reset, so that the movable mesh plate 41 closes the heat dissipation hole 12 again. When the device is in use, the heat dissipation hole 12 can be opened to enhance the heat dissipation effect. When not in use, the heat dissipation hole 12 can be closed to reduce the entry of dust.
