Description

Technical Field

[0001] This utility model relates to the field of heat dissipation structure technology, and in particular to a heat dissipation structure inside an electrical box device. Background Technology

[0002] With the continuous development of modern industry, electrical boxes have been widely used in various fields. Electrical boxes usually integrate a large number of electronic components. These components generate a lot of heat during operation. If heat cannot be dissipated in a timely and effective manner, the excessively high temperature will affect the performance and lifespan of the electronic components, and may even cause safety accidents.

[0003] First, most of the cooling fans in existing electrical boxes are installed in fixed positions, making it difficult to adjust their positions according to the heat generation of different components inside the box. Some industrial electrical boxes have complex internal component distributions, and the heat generation of components in different areas varies greatly. Fans in fixed positions can only dissipate heat in specific areas, and cannot effectively cover other heat-generating areas, leading to localized overheating and affecting the performance and stability of the entire electrical box.

[0004] Secondly, vibration and impact may cause components such as cooling fans to loosen, shift, or even be damaged, thereby reducing heat dissipation efficiency. Long-term vibration may also accelerate the wear of connecting parts, affecting the reliability of the entire heat dissipation structure and increasing the risk of equipment failure.

[0005] To address this, we propose an internal heat dissipation structure for electrical boxes to solve the problems mentioned above, such as the difficulty in adjusting the position of the fan according to the heat generation of different components inside the box, the significant differences in heat generation of components in different areas, the fact that a fan in a fixed position can only dissipate heat in a specific area and cannot effectively cover other heat-generating areas, leading to localized overheating, and the potential for vibration and impact to loosen, shift, or even damage components such as cooling fans, thereby reducing heat dissipation efficiency. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides an internal heat dissipation structure for electrical boxes, thereby resolving the issues raised in the background art, such as the difficulty in adjusting the position of components based on their heating characteristics, the significant differences in heat generation from different areas, the limitations of fixed-position fans which can only dissipate heat in specific areas and fail to effectively cover other areas, leading to localized overheating, and the potential for vibrations and impacts to loosen, shift, or even damage components such as cooling fans, thus reducing heat dissipation efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an internal heat dissipation structure for an electrical box, including a lifting mechanism, a limiting mechanism at the bottom of the lifting mechanism, and a main body mechanism at the bottom of the limiting mechanism;

[0008] The lifting mechanism includes a fixed plate, a pad fixedly connected to the top of the fixed plate, a pad block fixedly connected to the top of the pad, a groove formed on the top of the pad block, a roller fixedly connected within the groove, a sliding block sleeved on the surface of the roller, a first fixed shaft fixedly connected to the top of the sliding block, a connecting plate sleeved on the surface of the first fixed shaft, a second fixed shaft sleeved on the side of the connecting plate away from the first fixed shaft, side plates fixedly connected to both sides of the second fixed shaft, a shelf fixedly connected to the side plate away from the pad, a motor fixedly connected to the top of the shelf, a rotating shaft rotatably connected to the output end of the motor, and a fan fixedly connected to the rotating shaft away from the motor.

[0009] Preferably, the sliding block and the connecting plate are symmetrically distributed along a second fixed axis, there are two sliding blocks in the groove, the sliding blocks move the same distance, and the sliding block and the connecting plate are arranged in a triangle.

[0010] Preferably, the limiting mechanism includes a limiting plate with a groove at its top. A first limiting shaft is fixedly connected to the groove, and a second limiting shaft is sleeved inside the first limiting shaft. The second limiting shaft extends to the top of the first limiting shaft, and a limiting block is fixedly connected to the top of the second limiting shaft. A first connecting shaft is fixedly connected to one side of the limiting block, and a belt is sleeved on the surface of the first connecting shaft. A second connecting shaft is sleeved on the side of the belt away from the first connecting shaft, and a first support column is provided on one side of the second connecting shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The lifting mechanism allows for flexible height adjustment of the device. The rollers provide a smooth rolling track for the sliding block within the slide groove, making the movement of the sliding block more stable and effortless. Operators can change the position of the sliding block on the rollers according to the heat dissipation location and heat dissipation requirements of different components inside the electrical box. As the sliding block moves, the first fixed shaft, connecting plate, and second fixed shaft will move in tandem, thereby driving the side plate, shelf, and the motor and fan mounted on the shelf to rise or fall, precisely adjusting the heat dissipation components to the optimal heat dissipation position, greatly improving heat dissipation efficiency.

[0016] 2. Through the setting of the limiting mechanism, the vibration and impact force from the lifting mechanism can be absorbed and buffered during the operation of the equipment, reducing the impact on other parts of the electrical box equipment. At the same time, the first support column and the second support column are connected to the fixed plate and the placement plate respectively, which further enhances the stability of the entire device. This allows the limiting mechanism to maintain a good working condition while playing its limiting role, ensuring the smooth operation of the equipment. Attached Figure Description

[0024] Please see Figures 1 to 4 In the embodiments of this utility model;

[0025] Example 1: An internal heat dissipation structure for an electrical box includes a lifting mechanism 1, a limiting mechanism 2 at the bottom of the lifting mechanism 1, and a main body mechanism 3 at the bottom of the limiting mechanism 2.

[0026] The lifting mechanism 1 includes a fixed plate 101, a pad plate fixedly connected to the top of the fixed plate 101, a pad block 102 fixedly connected to the top of the pad plate, a groove opened on the top of the pad block 102, a roller fixedly connected in the groove, a sliding block 103 sleeved on the surface of the roller, a first fixed shaft 104 fixedly connected to the top of the sliding block 103, a connecting plate 105 sleeved on the surface of the first fixed shaft 104, a second fixed shaft 106 sleeved on the side of the connecting plate 105 away from the first fixed shaft 104, side plates fixedly connected to both sides of the second fixed shaft 106, a shelf 107 fixedly connected to the side plate away from the pad block 102, a motor fixedly connected to the top of the shelf 107, a rotating shaft rotatably connected to the output end of the motor, and a fan 108 fixedly connected to the side of the rotating shaft away from the motor.

[0027] The sliding block 103 and the connecting plate 105 are symmetrically distributed through the second fixed axis 106. There are two sliding blocks 103 in the groove. The sliding blocks 103 move the same distance. The sliding blocks 103 and the connecting plate 105 are arranged in a triangle.

[0028] Before the electrical box is started, the lifting mechanism 1 is in its initial position, the fixed plate 101 is securely installed inside the electrical box, the pad and block 102 are sequentially installed above the fixed plate 101, the roller in the slide groove is fixed, the two sliding blocks 103 are in their initial positions and connected to the connecting plate 105 through the first fixed shaft 104, the connecting plate 105 is sleeved with the second fixed shaft 106, the side plate is connected to the second fixed shaft 106 and the shelf 107, the motor and fan 108 are mounted on the shelf 107 and are in a stationary state. When it is necessary to dissipate heat inside the box 301, the operator pushes one of them. The sliding block 103 slides on the roller. Since the two sliding blocks 103 and the connecting plate 105 are symmetrically distributed through the second fixed shaft 106 and move the same distance, the other sliding block 103 will move synchronously. When the sliding block 103 slides on the roller, it drives the first fixed shaft 104 to move, thereby causing the connecting plate 105 to rotate around the second fixed shaft 106. Because the sliding block 103 and the connecting plate 105 are arranged in a triangle, this structure ensures the stability of the connecting plate 105 during the movement, so that the side plate, the shelf 107, the motor and the fan 108 connected to it can rise or fall smoothly as a whole.

[0029] Example 2: Refer to the attached instruction manual Figure 2-4It can be seen that the difference between Embodiment 2 and Embodiment 1 is that: the limiting mechanism 2 includes a limiting plate 201, the top of the limiting plate 201 is provided with a groove, a first limiting shaft 202 is fixedly connected in the groove, a second limiting shaft 203 is sleeved in the first limiting shaft 202, the second limiting shaft 203 extends to the top of the first limiting shaft 202, a limiting block 204 is fixedly connected to the top of the second limiting shaft 203, a first connecting shaft 205 is fixedly connected to one side of the limiting block 204, a belt 206 is sleeved on the surface of the first connecting shaft 205, a second connecting shaft 207 is sleeved on the side of the belt 206 away from the first connecting shaft 205, a first support column is provided on one side of the second connecting shaft 207, and a second support column is sleeved on the top of the first support column.

[0030] The second connecting shaft 207 is fixedly connected to the surface of the pad 102. The first support column and the second support column are fixedly connected to the fixing plate 101 and the shelf 107 respectively. The belt 206 and the connecting plate 105 are arranged in an X shape. The belt 206 is made of soft material.

[0031] Before the electrical box equipment is started, the limiting mechanism 2 is in its initial state. The limiting plate 201 is fixed in a suitable position below the fixed plate 101 of the lifting mechanism 1. The first limiting shaft 202 in the groove is fixed and stationary. The second limiting shaft 203 is sleeved in the first limiting shaft 202 and connected to the limiting block 204 at its top. The first connecting shaft 205 on the limiting block 204 is connected to the belt 206. The other end of the belt 206 is sleeved on the second connecting shaft 207 on the surface of the pad 102. The first support column and the second support column are fixedly connected to the fixed plate 101 and the shelf 107, respectively. The belt 206 and the connecting plate 105 are at an X-shape. With the X-shaped setting and under normal tension, when the lifting mechanism 1 descends, the placement plate 107 drives the second support column, the first support column, and the connected components to descend synchronously. At the same time, the limiting block 204 slides downward within the first limiting shaft 202 along with the second limiting shaft 203. During this process, the limiting mechanism 2 monitors the descending position of the lifting mechanism 1 in real time. During the operation of the lifting mechanism 1, whether it is rising or falling, the equipment may be subjected to vibration or external impact. At this time, the belt 206 made of soft material will play a buffering role. Since the belt 206 and the connecting plate 105 are set in an X-shape, when vibration or impact is transmitted, the belt 206 can absorb some energy through its own flexible deformation, reducing the impact on the lifting mechanism 1 and other components of the electrical box equipment. At the same time, the first support column and the second support column provide stable support for the entire structure, ensuring the stability of the overall structure of the limiting mechanism 2 during operation and ensuring the reliable realization of the limiting function.

[0032] Example 3: Refer to the appendix of the instruction manual Figure 3-4It can be seen that the difference between Embodiment 3 and Embodiments 2 and 3 is that: the main body 3 includes a box 301 and a machine body. A first buffer plate 302 is fixedly connected to the bottom of the box 301. A return spring 303 is fixedly connected to the bottom of the first buffer plate 302. A second buffer plate 304 is fixedly connected to the bottom of the return spring 303. Heat dissipation plates 305 are fixedly connected to both sides of the machine body. Heat dissipation grooves are opened on the surface of the heat dissipation plate 305.

[0033] The top of the first buffer plate 302 has a groove, the box body 301 is fixedly connected to the groove, the box body 301 has a through groove, the bottom of the inner wall of the box body 301 is fixedly connected to the fixing plate 101, and the top of the box body 301 is snapped with a cover plate.

[0034] During the assembly of the electrical box equipment, the first buffer plate 302 is first fixed to the bottom of the box body 301. Then, one end of the return spring 303 is connected to the bottom of the first buffer plate 302, and the other end is connected to the second buffer plate 304. Next, the box body 301 is fixed in the groove at the top of the first buffer plate 302 to ensure a firm connection. Heat dissipation plates 305 are installed on both sides of the box body 301. During the operation of the electrical box equipment, it may be subjected to external vibration or impact. When the vibration or impact force is transmitted to the box body 301, it is first borne by the second buffer plate 304. The second buffer plate 304 transmits the force to the return spring 303. The return spring 303 undergoes elastic deformation, absorbing and buffering part of the impact force. Then, the remaining impact force is further dispersed and buffered by the first buffer plate 302, thereby effectively protecting the electrical components inside the box body 301 and reducing the risk of component damage caused by vibration and impact.

[0035] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
