Description

Technical Field

[0001] This invention relates to the field of sealing products, and more specifically to a sealing assembly and an electrical cabinet. Background Technology

[0002] In existing electrical cabinets, power modules have through holes at both the top and bottom to communicate with other modules. To prevent water or dust from entering the power module through these through holes, sealing is usually required, such as by installing sealing rings around the through holes. Specifically, when the power module is inserted into the cabinet, the lower sealing ring contacts the cabinet and is deformed by the pressure of the cabinet and the power module, thus achieving a seal. Similarly, the upper sealing ring contacts the air cavity module and is deformed by the pressure of the air cavity module and the power module, thus achieving a seal. However, to ensure good sealing performance, the sealing ring needs to deform to a certain extent. Therefore, the dimensions of the power module (including the sealing ring) need to be interference-fitted with the insertion position to allow the sealing ring to deform. However, due to the interference fit, it is easy to interfere with the cabinet and air cavity module during insertion, resulting in difficult installation. Conversely, if the installation is smooth, the sealing performance is difficult to guarantee. Summary of the Invention

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a sealing assembly and an electrical cabinet. To achieve the above objective, this invention and its preferred embodiments adopt the following technical solutions, but the embodiments are not limited to the following solutions:

The guide hole includes a first segment and a second segment that are interconnected and arranged sequentially along a first direction. The first segment and the second segment are respectively provided with a first support surface and a second support surface. When the moving part slides to the first position and the second position, it is supported by the first support surface and the second support surface, respectively.

[0019] Option 10: An electrical cabinet comprising a sealing assembly as described in any one of Options 1 to 9, wherein the insert is a power module and the moving part is a wind cavity module.

[0020] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0021] 1. In Scheme 1 and its preferred embodiments, a sealing assembly includes a body, a moving part, and an insert.

[0022] The main body has an insertion cavity; the moving part is adapted to move relative to the main body in a first position and a second position to move closer to or further away from the insert. The insert is adapted to be inserted into the insertion cavity along a first direction, and its two ends perpendicular to the first direction in a second direction are respectively provided with a first sealing area and a second sealing area. A first sealing part is provided on the main body or the insert, surrounding the first sealing area. The main body and the insert respectively press against the two ends of the first sealing part to achieve a seal in the first sealing area. A second sealing part is provided on the insert or the moving part, surrounding the second sealing area. When the moving part moves to the first position, the moving part and the insert respectively press against the two ends of the second sealing part to achieve a seal in the second sealing area, and the moving part is at least adapted to stop at the first position to prevent the second sealing part from rebounding and causing the seal in the second sealing area to fail. In the second position, the moving part moves away from the insert to disengage the second sealing part from the moving part and the insert, so that the size of the insertion cavity can be larger than the size of the insert, facilitating the insertion or removal of the insert from the insertion cavity, realizing installation or disassembly, thereby simultaneously satisfying sealing and ease of installation and disassembly.

[0023] 2. In Scheme 2 and its preferred embodiments, the moving part is rotatably or slidably connected to the body to move between the first position and the second position, so as to realize the change of position.

[0024] 3. In Scheme 3 and its preferred embodiments, the moving part is located above or below the insert, and the moving part is slidably connected to the body. The moving part is supported by the body in both the first and second positions, so that the moving part has a support position in both positions and will not slip due to its own weight. Therefore, it is not necessary to keep the position of the moving part when installing or removing the insert, which is more convenient.

[0025] 4. In Scheme 4 and its preferred embodiments, one of the body and the moving part is provided with a guide hole, and the other of the two is provided with a guide post that slides with the guide hole. The guide hole includes a first segment and a second segment that are interconnected and arranged sequentially along a first direction. The first segment and the second segment are respectively provided with a first support surface and a second support surface. When the moving part slides to the first position and the second position, it is supported by the first support surface and the second support surface respectively, so as to realize the support and movement guidance at the two positions.

[0026] 5. In Scheme 5 and its preferred embodiments, the first segment is an inclined segment that extends along the first direction and tilts upwards, and the second segment is a horizontal segment. The corresponding position change can be achieved directly by pushing or pulling along the first direction without lifting upwards, which is more convenient and particularly suitable for use in narrow electrical cabinets with only one side having operating space.

[0027] 6. In Scheme 6 and its preferred embodiments, when the moving part is in the first position, it stops at the first position by gravity and / or by being detachably fixed to the body or the insert, thereby fixing the position of the moving part and ensuring the stability of the seal during use.

[0028] 7. In Scheme 7 and its preferred embodiments, the surface of the main body facing the first sealing part is provided with a first inclined surface, and the first inclined surface gradually approaches the moving part along the first direction. The insert is provided with a second inclined surface that matches the first inclined surface. The extension direction of the first sealing part is the same as the extension direction of the first inclined surface, and both ends are adapted to abut against the first inclined surface and the second inclined surface, respectively, so that the insert only abuts against the first sealing part when the insert is inserted, thereby achieving a seal, preventing damage to the first sealing part during the insertion process, and facilitating insertion and installation. Conversely, it is also convenient to disassemble.

[0029] 8. In Scheme 8 and its preferred embodiments, the insert is typically cantilevered relative to the force application position (such as the hand). If the weight of the insert is large, it is prone to tilting, leading to inconvenience in installation or disassembly. By providing a horizontal guide surface parallel to the first direction in the insertion cavity, the insert is adapted to sit on and slide along the horizontal guide surface until both ends of the first sealing part are adapted to abut against the first inclined surface and the second inclined surface, respectively. During insertion, the insert is supported by the horizontal guide surface, making installation and disassembly easier.

[0030] 9. In Scheme 9 and its preferred embodiments, during the movement of the moving part toward the first position, the insert is pressed against the insert to bring it closer to the body, and the body and the insert press against the two ends of the first sealing part respectively to further compress the first sealing part and make the sealing effect of the first sealing area better.

[0031] 10. In Scheme 10 and its preferred embodiments, an electrical cabinet includes the above-mentioned sealing assembly, the insert is a power module and the moving part is a wind cavity module, which has the beneficial effects brought about by the above-mentioned sealing assembly.

[0050] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0051] refer to Figures 1-11 An electrical cabinet includes a sealing assembly, which comprises a body 1, a moving part 2, an insert 3, a first sealing part 4, and a second sealing part 5. In other embodiments, the sealing assembly can be used on other products.

[0052] refer to Figure 1 , Figure 2The main body 1 is the cabinet body, and it has an insertion cavity 11. In this embodiment, the insertion cavity 11 has openings on the top and front sides. The side walls on the left and right sides of the insertion cavity 11 form guide rails 12. The guide rails 12 have horizontal guide surfaces 121 parallel to the first direction, and the horizontal guide surfaces 121 face upwards. The bottom of the insertion cavity 11 has a first inclined surface 13, which faces the first sealing part 4 and gradually moves towards the moving part 2 located above the first inclined surface 13 along the first direction. In this embodiment, the first direction is from front to back, and the closer the first inclined surface 13 is to the rear side, the closer it is to the moving part 2. The main body 1 also has a first through hole 14, the upper end of which opens into the first inclined surface 13. (Reference) Figure 8 The main body 1 also has guide holes 15 on its left and right side walls. Each guide hole 15 includes a first segment 151 and a second segment 152 that are interconnected and sequentially arranged along a first direction. The first segment 151 has an upward-facing first support surface 1511, and the second segment 152 has an upward-facing second support surface 1521. The first segment 151 is an inclined segment extending along the first direction and tilting upwards; the second segment 152 is a horizontal segment and is higher than the first segment 151. In other embodiments, the first segment 151 and the second segment 152 can be perpendicular to each other. Of course, the second segment 152 can also be a downward-sloping segment, as long as the bottom of the second segment 152 is higher than the bottom of the first segment 151.

[0053] The moving member 2 is located within the insertion cavity 11, or the moving member 2 has a portion that can extend into the insertion cavity 11 (this portion is used to press against the second sealing portion 5) to seal with the insert 3 within the insertion cavity 11. The moving member 2 is adapted to move relative to the body 1 between a first position and a second position. In this embodiment, reference is made to... Figure 9 The moving component 2 is a ventilation cavity module, which has a ventilation cavity 21 and is located above the insert 3. A fan is installed inside the ventilation cavity 21 for heat dissipation. In other embodiments, the moving component 2 may be located below the insert 3. In this embodiment, the ventilation cavity module is slidably connected to the body 1 to move between a first position and a second position. Specifically, refer to... Figure 8 The moving part 2 is provided with a guide post 22 that slides in conjunction with the guide hole 15. When the moving part 2 slides to the first position, the guide post 22 is located at the bottom of the first segment 151 and supported by the first support surface 1511. When the moving part 2 slides to the second position, the guide post 22 is located within the second segment 152 and supported by the second support surface 1521. Therefore, in this embodiment, when the moving part 2 slides to the second position, it slides upward and backward, and vice versa. In other embodiments, the moving part 2 may also slide only in the vertical direction between the first and second positions. It should be understood that in other embodiments, the above effect can also be achieved by the moving part 2 being provided with a sliding hole and the body 1 being provided with a guide post 22. In other embodiments, the moving part 2 may also be rotatably connected to the body 1 to move between the first and second positions.

[0054] refer to Figures 3-6 The insert 3 is adapted to be inserted into the insertion cavity 11 along a first direction. Its two ends, perpendicular to the first direction and in a second direction, are respectively provided with a first sealing area 31 and a second sealing area 32. The second direction can be vertical or horizontal; in this embodiment, the second direction is vertical. The first sealing area 31 and the second sealing area 32 can be through holes communicating with the cavities of the body 1 and the moving part 2, or they can be precision parts requiring waterproofing and dustproofing, such as a charging dock. In this embodiment, reference is made to… Figure 9 The insert 3 is a power module. The first sealing area 31 and the second sealing area 32 are through holes communicating with the first through hole 14 and the ventilation cavity 21, respectively, for heat dissipation of the power module. (Reference) Figure 3 The bottom of the insert 3 is provided with a second inclined surface 33 that is adapted to the first inclined surface 13, and the second inclined surface 33 is parallel to the first inclined surface 13.

[0055] refer to Figure 3 , Figure 6 The left and right sides of the insert 3 are respectively provided with sliders 34 suitable for sitting on the horizontal guide surface 121. The sliders 34 are suitable for sliding along the horizontal guide surface 121 so that the insert 3 is inserted into the insertion cavity 11 in the first direction, or withdrawn from the insertion cavity 11 in the opposite direction of the first direction.

[0056] refer to Figure 1 , Figure 2 and Figure 11 The first sealing part 4 is disposed on the body 1. The first sealing part 4 is flexible and surrounds the first sealing area 31 to achieve a seal in the first sealing area 31. In other embodiments, the first sealing part 4 may also be disposed on the insert 3. In this embodiment, the first sealing part 4 is formed by an annular sealing strip. In other embodiments, when the body 1 or the insert 3 has a flexible end face, the first sealing part 4 may also be formed by the flexible end face. The insert 3 is situated on the horizontal guide surface 121 and slides along the horizontal guide surface 121 until both ends of the first sealing part 4 are adapted to abut against the first inclined surface 13 of the body 1 and the second inclined surface 33 of the insert 3, respectively, to achieve a seal in the first sealing area 31.

[0057] refer to Figure 3 , Figure 4 and Figure 10The second sealing part 5 is located above the insert 3. The second sealing part 5 is flexible and surrounds the second sealing area 32. In other embodiments, the second sealing part 5 may also be located below the moving part 2. In this embodiment, the second sealing part 5 is also formed by an annular sealing strip. When the moving part 2 moves to the first position, the moving part 2 and the insert 3 respectively press against both ends of the second sealing part 5. In the second position, the moving part 2 moves away from the insert 3, causing the second sealing part 5 to disengage from the moving part 2 and the insert 3, allowing the insert 3 to exit or be inserted into the insertion cavity 11. In this embodiment, since the moving part 2 is in its normal operating state in the first position, to prevent the elasticity of the second sealing part 5 from causing the moving part 2 to move and resulting in poor sealing, the moving part 2 must at least stop in the first position to ensure a good sealing effect. Specifically, when the moving part 2 is in the first position, it stops in the first position by gravity and / or by being detachably fixed to the body 1 or the insert 3. The moving part 2 is fixed to the body 1 or the insert 3 in a detachable manner, including but not limited to snap-fit, screw connection, magnetic connection, etc.

[0058] In this embodiment, the moving member 2 is located above the insert 3. Therefore, the gravity of the moving member 2 is applied to the second sealing part 5, thereby ensuring that the moving member 2 and the insert 3 abut against the two ends of the second sealing part 5 respectively. Furthermore, by using a screw to pass through the insert 3 and lock it with the moving member 2 (or by using a nut), the second sealing part 5 can be further compressed, improving the sealing effect and restricting the movement of the moving member 2 relative to the insert 3. Similarly, to restrict the movement of the insert 3 relative to the body 1, the insert 3 and the body 1 can also be locked with screws.

[0059] In use, first push the moving part 2 backward, causing it to slide to the second position. At this point, the insertion cavity 11 is larger than the insertion part 3, facilitating insertion. The insertion part 3 rests on the horizontal guide surface 121 and slides along it until both ends of the first sealing part 4 are adapted to abut against the first inclined surface 13 of the body 1 and the second inclined surface 33 of the insertion part 3, respectively, achieving a seal in the first sealing area 31. Then, push the moving part 2 forward, causing it to move to the first position. The moving part 2 gradually approaches the insertion part 3, causing both ends of the second sealing part 5 to abut against the moving part 2 and the insertion part 3, respectively, achieving a seal in the second sealing area 32. Finally, secure the moving part 2 to the insertion part 3 and the insertion part 3 to the body 1 with screws to complete the installation.

[0060] During disassembly, first remove the screws, then push the moving part 2 backward so that the moving part 2 slides to the second position, and then the insert 3 slides along the horizontal guide surface 121 and exits the insertion cavity 11, thereby completing the disassembly of the insert 3.

[0061] Compared with the prior art, this embodiment has the following beneficial effects:

[0062] In one exemplary embodiment, a sealing assembly includes a body 1, a moving part 2, and an insert 3.

[0063] The main body 1 is provided with an insertion cavity 11; the moving member 2 is adapted to move relative to the main body 1 to a first position and a second position, so as to move closer to or further away from the insert 3. The insert 3 is adapted to be inserted into the insertion cavity 11 along a first direction, and its two ends perpendicular to the first direction are respectively provided with a first sealing area 31 and a second sealing area 32. A first sealing part 4 is provided on the main body 1 or the insert 3, and surrounds the first sealing area 31. The main body 1 and the insert 3 respectively press against the two ends of the first sealing part 4 to achieve the sealing of the first sealing area 31. A second sealing part 5 is provided on the insert 3 or the moving member 2, and surrounds the second sealing area 32. When the moving member 2 moves to the first position, the moving member 2 and the insert 3 respectively press against the two ends of the second sealing part 5 to achieve the sealing of the second sealing area 32, and the moving member 2 is at least adapted to stop at the first position, thereby preventing the second sealing part 5 from rebounding and causing the sealing of the second sealing area 32 to fail. In the second position, the moving part 2 moves away from the insert 3, so that the second sealing part 5 is disengaged from the moving part 2 and the insert 3, so that the size of the insertion cavity 11 can be larger than the size of the insert 3, making it easier for the insert 3 to be inserted into or removed from the insertion cavity 11, thus achieving installation or disassembly, thereby simultaneously satisfying sealing and easy disassembly.

[0064] In one exemplary embodiment, the moving member 2 is rotatably or slidably connected to the body 1 to move between a first position and a second position, thereby achieving a change in position.

[0065] In one exemplary embodiment, the moving part 2 is located above or below the insert 3. The moving part 2 is slidably connected to the body 1. The moving part 2 is supported by the body 1 in both the first and second positions, so that the moving part 2 has a support position in both positions and will not slip due to its own weight. Therefore, it is not necessary to keep the position of the moving part 2 when installing or removing the insert 3, which is more convenient.

[0066] In one exemplary embodiment, one of the body 1 and the moving part 2 is provided with a guide hole 15, and the other is provided with a guide post 22 that slides in cooperation with the guide hole 15. The guide hole 15 includes a first segment 151 and a second segment 152 that are interconnected and arranged sequentially along a first direction. The first segment 151 and the second segment 152 are respectively provided with a first support surface 1511 and a second support surface 1521. When the moving part 2 slides to the first position and the second position, it is supported by the first support surface 1511 and the second support surface 1521 respectively, so as to achieve support and motion guidance at the two positions.

[0067] In one exemplary embodiment, the first segment 151 is an inclined segment that extends along a first direction and tilts upwards, while the second segment 152 is a horizontal segment. The corresponding position change can be achieved directly by pushing or pulling along the first direction without lifting upwards, which is more convenient and particularly suitable for use in narrow electrical cabinets with only one side having operating space.

[0068] In one exemplary embodiment, when the moving part 2 is in the first position, it stops at the first position by gravity and / or by being detachably fixed to the body 1 or the insert 3, thereby fixing the position of the moving part 2 and ensuring the stability of the seal during use.

[0069] In one exemplary embodiment, the surface of the body 1 facing the first sealing part 4 is provided with a first inclined surface 13, and the first inclined surface 13 gradually approaches the moving part 2 along a first direction. The insert 3 is provided with a second inclined surface 33 that is adapted to the first inclined surface 13. The extension direction of the first sealing part 4 is the same as the extension direction of the first inclined surface 13, and both ends are adapted to abut against the first inclined surface 13 and the second inclined surface 33 respectively, so that the insert 3 only abuts against the first sealing part 4 when the insertion is completed, thereby achieving a seal, preventing damage to the first sealing part 4 during the insertion process, and facilitating insertion and installation. Conversely, it is also convenient for disassembly.

[0070] In one exemplary embodiment, the insert 3 is typically cantilevered relative to the force application position (such as the hand). If the weight of the insert 3 is large, it is prone to tilting, making installation or disassembly inconvenient. The insertion cavity 11 is provided with a horizontal guide surface 121 parallel to the first direction. The insert 3 is adapted to sit on the horizontal guide surface 121 and slide along it until both ends of the first sealing portion 4 are adapted to abut against the first inclined surface 13 and the second inclined surface 33, respectively. During insertion, the insert 3 is supported by the horizontal guide surface 121, making installation and disassembly easier.

[0071] In one exemplary embodiment, an electrical cabinet includes the aforementioned sealing assembly, with the insert 3 being a power module and the moving part 2 being a ventilation module, and it has the beneficial effects brought about by the aforementioned sealing assembly.

[0072] Example 2:

[0073] In Embodiment 1, the sealing of the first sealing area 31 and the second sealing area 32 are independent and do not affect each other. In this embodiment, during the sealing process of the second sealing area 32, the sealing effect of the first sealing area 31 is also improved. Specifically, during the movement of the moving member 2 towards the first position, it presses against the insert 3, causing the insert 3 to move closer to the body 1, and the body 1 and the insert 3 respectively press against both ends of the first sealing part 4 to further compress the first sealing part 4, thereby improving the sealing effect of the first sealing area 31.

[0074] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
