Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The following is for reference. Figures 1-5 The air conditioning unit according to the embodiment of the present utility model has a simple structure, which can reduce the installation cost and has low requirements for assembly precision, thereby improving installation efficiency and production efficiency.

[0030] like Figures 1-5 As shown, an air conditioning unit according to an embodiment of the present invention includes: a mounting plate 1, a protective cover 2, components 3, and a sealing sponge 4.

[0031] The protective cover 2 is connected to the mounting plate 1 and together with the mounting plate 1 defines the receiving space 24. The component 3 is installed in the receiving space 24. The sealing sponge 4 is located between the protective cover 2 and the mounting plate 1. The component 3 is connected to a wire harness, which passes through the sealing sponge 4 and extends to the outside of the receiving space 24.

[0032] An air conditioner, also known as an air conditioning unit, is a machine that provides cooling and temperature control to a space (usually enclosed). Its function is to regulate parameters such as temperature, humidity, cleanliness, and airflow within a room (or enclosed space / area) by producing cool or warm air to meet the requirements of human comfort or industrial processes.

[0033] Specifically, the air conditioning unit is equipped with a main frame, which is located on the outermost side of the air conditioning unit and can also be staggered inside the air conditioning unit to provide support for the air conditioning unit. The main frame forms an installation space inside, where the components of the air conditioning unit can be installed. The main frame can protect the components and also provide installation points for the components inside the air conditioning unit, ensuring installation reliability. The air conditioning unit is equipped with a mounting plate 1, which can be connected to the main frame through connectors such as bolts. The structure is simple, the installation is convenient, and the setup cost is low.

[0034] Furthermore, the air conditioning unit contains component 3, which can be installed on the mounting plate 1 via connectors, welding, or bonding. Connectors can be bolts, etc., resulting in a simple structure, convenient installation, and low cost. Component 3 can be a contactor, a widely used switching device that utilizes electromagnetic, pneumatic, or hydraulic principles to control the main circuit's on / off state. Contactors offer advantages such as strong current interruption capability, rapid action, safe operation, frequent operation, and remote control, thus ensuring the air conditioning unit's safety. The contactor is also connected via wiring harnesses to electrically connect with other components 3, ensuring the safety of the remaining components 3. For example, Figure 3 As shown, the left side of the mounting plate 1 can be used to install structures such as electrical control boards, and the right side of the mounting plate 1 can be used to install structures such as contactors, so that the components 3 are spaced apart and the reliability of operation of each component 3 is guaranteed.

[0035] Furthermore, the air conditioning unit is also equipped with a protective cover 2. The protective cover 2 can be connected to the mounting plate 1 by means of connectors or welding. The protective cover 2 is set as a semi-enclosed structure. After the protective cover 2 is connected to the mounting plate 1, it can jointly define the accommodating space 24 with the mounting plate 1. That is, the mounting plate 1 can close the protective cover 2, and the components 3 can be placed in the accommodating space 24, thereby making the components 3 isolated from the outside world, preventing the refrigerant and other substances in the air conditioner from contacting the components 3, and improving the safety of use.

[0036] Furthermore, a sealing sponge 4 is provided between the protective cover 2 and the mounting plate 1. The sealing sponge 4 can seal the gap between the protective cover 2 and the mounting plate 1, ensuring the operational reliability of the component 3. The wire harness connected to the component 3 can be passed through the sealing sponge 4 to extend outside the receiving space 24, thereby enabling the component 3 to be electrically connected to other external components 3, ensuring the operational reliability of the air conditioning unit. The sealing sponge 4 has low density, good elasticity and softness, and can spontaneously avoid the wire harness. Thus, while sealing the gap between the protective cover 2 and the mounting plate 1, the sealing sponge 4 can also allow the wire harness to extend from inside the receiving space 24 to outside the receiving space 24. The installation cost is low, and the requirement for the accuracy of the wire harness insertion position can be reduced, thereby improving installation efficiency and production efficiency. In actual installation, the sealing sponge 4 can be replaced with a material with the same properties to improve the flexibility of the installation.

[0037] According to the embodiment of the present utility model, the air conditioner unit can protect the components 3 in the accommodating space 24 by setting a sealing sponge 4 between the protective cover 2 and the mounting plate 1, which can ensure the safety of use, the structure is simple, the installation cost can be reduced, and the requirements for the accuracy of the wiring harness installation position can be reduced, thereby improving the installation efficiency and production efficiency, the use effect is better, and the application range is wider.

[0038] In some embodiments, the protective cover 2 is bonded with sealing sponge 4, and / or the mounting plate 1 is bonded with sealing sponge 4.

[0039] Specifically, a sealing sponge 4 is provided between the protective cover 2 and the mounting plate 1. The sealing sponge 4 can seal the gap between the protective cover 2 and the mounting plate 1 to ensure the reliability of the component 3. The protective cover 2 is bonded with the sealing sponge 4, and / or the mounting plate 1 is bonded with the sealing sponge 4. The sealing sponge 4 can be bonded only to the protective cover 2, only to the mounting plate 1, or both the protective cover 2 and the mounting plate 1 can be bonded with the sealing sponge 4, which improves the flexibility of the setting. In this embodiment, the sealing sponge 4 is bonded to the mounting plate 1.

[0040] Furthermore, when the protective cover 2 is bonded with sealing sponge 4, the protective cover 2 can cover the component 3, and the wire harness of the component 3 can extend from the receiving space 24. The protective cover 2 can also press the sealing sponge 4 towards the mounting plate 1 and the wire harness, thereby sealing the gap between the protective cover 2 and the mounting plate 1. When the mounting plate 1 is bonded with sealing sponge 4, the protective cover 2 can cover the component 3, and the wire harness of the component 3 can extend from the receiving space 24. The protective cover 2 can also press the wire harness towards the sealing sponge 4 of the mounting plate 1, thereby sealing the gap between the protective cover 2 and the mounting plate 1. When both the protective cover 2 and the mounting plate 1 are bonded with sealing sponge 4, the protective cover 2 can cover the component 3, and the wire harness of the component 3 can extend from the receiving space 24. Both the protective cover 2 and the mounting plate 1 can press the sealing sponge 4 towards the wire harness, thereby sealing the gap between the protective cover 2 and the mounting plate 1, ensuring sealing reliability, and thus improving the safety of using the component 3.

[0041] In some embodiments, both the protective cover 2 and the mounting plate 1 are bonded with sealing sponges 4, and the wire harness passes between two sealing sponges 4.

[0042] Specifically, a sealing sponge 4 is provided between the protective cover 2 and the mounting plate 1, and both the protective cover 2 and the mounting plate 1 can be bonded with sealing sponges 4. That is, the side of the protective cover 2 closest to the mounting plate 1 is bonded with sealing sponge 4, and the side of the mounting plate 1 closest to the protective cover 2 is also bonded with sealing sponge 4. When the protective cover 2 is installed on the mounting plate 1, the sealing sponges 4 of the protective cover 2 and the sealing sponges 4 of the mounting plate 1 can be squeezed towards each other, thereby sealing the space between the protective cover 2 and the mounting plate 1. The wire harness can be passed between the two sealing sponges 4, so that the two sealing sponges 4 can squeeze the wire harness from both sides to seal the circumference of the wire harness, and can also provide flexible protection for the wire harness, ensuring airtightness while extending the service life of the wire harness.

[0043] In some embodiments, the mounting plate 1 has a first annular mating surface 11 distributed around the component 3, the protective cover 2 has a second annular mating surface 23 distributed around the component 3, and the sealing sponge 4 is sandwiched between the second annular mating surface 23 and the first annular mating surface 11.

[0044] Specifically, the protective cover 2 can be connected to the mounting plate 1 by welding or connectors, and as follows: Figure 3 As shown, the mounting plate 1 is provided with a first annular mating surface 11, and the first annular mating surface 11 is distributed around the component 3. The first annular mating surface 11 can be set as a circular ring, a rectangular ring or a polygonal ring structure. The first annular mating surface 11 can be set according to the specific shape of the component 3 so that the component 3 can be fully distributed within the first annular mating surface 11.

[0045] Furthermore, such as Figures 4-5 As shown, the protective cover 2 also has a second annular mating surface 23, and the second annular mating surface 23 is also distributed around the component 3. The second annular mating surface 23 can be set as a circular ring, a rectangular ring or a polygonal ring structure. The second annular mating surface 23 can be set according to the specific shape of the component 3 so that the component 3 can be fully distributed within the second annular mating surface 23.

[0046] Furthermore, the first annular mating surface 11 and the second annular mating surface 23 are correspondingly arranged, and the sealing sponge 4 can be sandwiched between the second annular mating surface 23 and the first annular mating surface 11. That is, when the protective cover 2 is installed on the mounting plate 1, the first annular mating surface 11 and the second annular mating surface 23 are connected, and the sealing sponge 4 can seal the gap between the first annular mating surface 11 and the second annular mating surface 23. At the same time, the first annular mating surface 11 and the second annular mating surface 23 are distributed around the component 3, so that the sealing sponge 4 can seal the component 3 in the circumferential direction, improve the sealing reliability, and ensure the safety of the component 3 in use.

[0047] In some embodiments, the sealing sponge 4 is constructed as a ring structure, the protective cover 2 is mounted on the mounting plate 1, and the protective cover 2 and the mounting plate 1 together define the receiving space 24. The component 3 can be installed in the receiving space 24, and the sealing sponge 4 can be disposed between the protective cover 2 and the mounting plate 1, thereby sealing the gap between the protective cover 2 and the mounting plate 1. The sealing sponge 4 can be constructed as a ring structure, and the ring-shaped sealing sponge 4 can be distributed around the component 3, thereby sealing all parts of the component 3 in the circumferential direction to improve the sealing effect. The component 3 is connected to a wire harness, and the sealing sponge 4 is disposed in the circumferential direction of the component 3, so that the wire harness can pass through the receiving space 24 from any position in the circumferential direction of the component 3, improving the flexibility of the installation and reducing the requirements for assembly accuracy, thereby improving the installation efficiency and production efficiency.

[0048] In some embodiments, the air conditioning unit further includes a support member 12, which is located between the protective cover 2 and the mounting plate 1, and the structural strength of the support member 12 is greater than the structural strength of the sealing sponge 4.

[0049] Specifically, the protective cover 2 can be installed on the mounting plate 1 by welding or connecting parts, and as follows: Figure 1 As shown, the air conditioning unit is also provided with a support member 12. The support member 12 is located between the protective cover 2 and the mounting plate 1. The support member 12 can be located on the protective cover 2 and connected to the protective cover 2 by welding or other means, or it can be integrally formed with the protective cover 2. The support member 12 is located on the side of the protective cover 2 near the mounting plate 1 and protrudes towards the mounting plate 1. The support member 12 can also be located on the mounting plate 1 and connected to the mounting plate 1 by welding or other means. The setting method is flexible. Alternatively, it can be integrally formed with the mounting plate 1. The support member 12 is located on the side of the mounting plate 1 near the protective cover 2 and protrudes towards the protective cover 2. The setting method is flexible.

[0050] Furthermore, the structural strength of the support member 12 is set to be greater than that of the sealing sponge 4. That is, the support member 12 can be made of steel or the like. When the protective cover 2 is installed on the mounting plate 1, the support member 12 can be supported between the protective cover 2 and the mounting plate 1, and the sealing sponge 4 can seal the remaining parts of the protective cover 2 and the mounting plate 1. This ensures that when the wire harness passes through the sealing sponge 4, the protective cover 2 and the mounting plate 1 will not squeeze the wire harness, thus extending the service life of the wire harness and ensuring the reliability of the wire harness. In addition, when setting the sealing sponge 4, a hole-like structure can be set in the sealing sponge 4 to avoid the support member 12. The sealing sponge 4 can also be installed on the outside or inside of the support member 12 to improve the flexibility of the setting.

[0051] In some embodiments, the thickness of the sealing sponge 4 in its naturally elongated state is greater than the thickness of the support member 12.

[0052] Specifically, such as Figure 1 As shown, a sealing sponge 4 and a support member 12 are provided between the protective cover 2 and the mounting plate 1. The sealing sponge 4 can seal the gap between the protective cover 2 and the mounting plate 1, and the support member 12 can prevent the protective cover 2 and the mounting plate 1 from squeezing the wire harness, ensuring the reliability of the wire harness. The thickness of the sealing sponge 4 in its naturally stretched state is greater than the thickness of the support member 12. That is, when the protective cover 2 is installed on the mounting plate 1, the protective cover 2 can first squeeze the sealing sponge 4, so that the sealing sponge 4 wraps the wire harness to seal the circumference of the wire harness. As the protective cover 2 continues to move toward the mounting plate 1, the protective cover 2 can press against the support member 12. The thickness of the support member 12 can be set to be greater than the radial dimension of the wire harness, so as to ensure the sealing performance while preventing the protective cover 2 and the mounting plate 1 from squeezing the wire harness, ensuring the reliability of the wire harness operation.

[0053] Furthermore, multiple support members 12 can be provided, and the multiple support members 12 can be distributed at intervals in the circumferential direction of the component 3, so that multiple support members 12 can be provided between the protective cover 2 and the mounting plate 1. The thickness of the multiple support members 12 is set to be the same, so that a gap for threading the wire harness can be formed between the protective cover 2 and the mounting plate 1, avoiding the wire harness being squeezed and causing connection failure, and improving the reliability of the wire harness.

[0054] In some embodiments, the support member 12 is connected to the mounting plate 1, and the support member 12 is constructed as a nut. The protective cover 2 is provided with a mounting hole 25, and the nut is provided in correspondence with the mounting hole 25. The connector is adapted to pass through the mounting hole 25 to be connected to the nut.

[0055] Specifically, a support member 12 is provided between the protective cover 2 and the mounting plate 1, and as follows: Figure 3 As shown, the support member 12 can be installed on the mounting plate 1 by welding or other means, and protrudes from the mounting plate 1 toward the protective cover 2. The support member 12 can be constructed as a nut, and as shown... Figure 2 As shown, the protective cover 2 is provided with mounting holes 25, which can be correspondingly set with nuts, so that the connecting parts can be inserted through the mounting holes 25 to be connected with the nuts. The connecting parts can be bolts, etc., so that the nuts can support the protective cover 2 and the mounting plate 1, and can also connect the protective cover 2 and the mounting plate 1, which can reduce the number of parts and thus reduce the installation cost.

[0056] Furthermore, multiple nuts can be provided, i.e., two, three, or four nuts, etc., and multiple mounting holes 25 can be provided, i.e., two, three, or four mounting holes 25, etc., and multiple nuts and multiple mounting holes 25 can be set one-to-one. Alternatively, the number of nuts can be set to be greater than the number of mounting holes 25, i.e., the number of nuts must be greater than or equal to the number of mounting holes 25. Setting multiple nuts and mounting holes 25 can improve the reliability of the connection between the protective cover 2 and the mounting plate 1, and can ensure the reliability of the nuts supporting the protective cover 2 and the mounting plate 1.

[0057] In some embodiments, the protective cover 2 includes a connected mounting portion 21 and a receiving portion 22. The mounting portion 21 is annular and is disposed around the receiving portion 22. The mounting portion 21 is connected to the mounting plate 1 and has a through hole 211. The component 3 is adapted to pass through the through hole 211 to extend into the receiving portion 22.

[0058] Specifically, the protective cover 2 can be installed on the mounting plate 1 by welding or connecting parts, so as to define, together with the mounting plate 1, a receiving space 24 for accommodating the component 3, and as... Figure 4As shown, the protective cover 2 includes a mounting part 21 and a receiving part 22. The mounting part 21 and the receiving part 22 can be connected by welding or integral molding, and the receiving part 22 is connected to the side of the mounting part 21 away from the mounting plate 1. The receiving part 22 and the mounting part 21 are connected. The mounting part 21 is constructed as a ring structure, and the ring-shaped mounting part 21 can be arranged around the receiving part 22. The mounting part 21 can be connected to the mounting plate 1, so that the protective cover 2 can be installed on the mounting plate 1.

[0059] Furthermore, the mounting part 21 is constructed as a ring structure and has a through hole 211. When the protective cover 2 is placed over the component 3, the component 3 can extend into the receiving part 22 through the through hole 211. The cross-sectional area of ​​the receiving part 22 is set to be smaller than the opening area of ​​the through hole 211. Setting the opening area of ​​the through hole 211 to be larger facilitates installation. After installation, the receiving part 22 can limit the component 3 to ensure the reliability of the component 3 installation.
