[0033] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] The relay structure according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0035] This utility model provides a relay, such as Figure 1 As shown, it includes: a main body 1 and a base 2. The main body 1 includes a housing 11 and a pressing member 12. A support part 13 is provided at the bottom of the housing 11. The support part 13 has an opening. At least a portion of the base 2 extends into the interior of the main body 1 through the opening and is supported on the support part 13. The pressing member 12 is provided inside the main body 1 and abuts against at least a portion of the base 2.

[0036] like Figure 1 As shown, by setting up a main body 1, a base 2, a housing 11, a pressing member 12, a support part 13, and a support part opening 14, at least part of the base 2 enters the support part 13 through the support part opening 14 and is supported on the support part 13. The support part 13 has an upward supporting force on at least part of the base 2, and the pressing member 12 inside the main body 1 has a downward pressure on at least part of the base 2, so as to achieve the purpose of flexible loading, unloading and fixing.

[0037] In one embodiment, such as Figure 2 As shown, the pressing member 12 includes a body portion 121 and a bent portion 122. The body portion 121 is the main part of the pressing member 12. The body portion 121 is fixed inside the main body 1, and its shape and size match the cavity inside the main body 1 to ensure that the pressing member 12 can be stably installed inside the main body 1. The bent portion 122 is fixed to the body portion 121. The bent portion 122 extends from one side of the main body 1 and bends towards the bottom of the main body 1. This design allows the bent portion 122 to make effective contact and clamp with the base 2.

[0038] Specifically, when the main body 1 rotates to a certain angle, the bent portion 122 will press against at least part of the base 2, thereby achieving a stable connection between the main body 1 and the base 2. This connection method not only improves the ease of installation and disassembly of the relay, but also effectively prevents the base 2 from loosening during operation.

[0039] In one embodiment, such as Figure 2 and Figure 3 As shown, in order to achieve the pressing of the bent portion 122 against the base 2, a limiting protrusion 123 and a limiting groove 211 are also designed in this embodiment. The bent portion 122 is provided with the limiting protrusion 123, and the base cover 21 is provided with the limiting groove 211. When the main body 1 and the base 2 are installed together, the limiting protrusion 123 will match the shape of the limiting groove 211, and the limiting protrusion 123 will enter the limiting groove 211 to achieve the limiting purpose.

[0040] Optionally, either the limiting protrusion 123 or the limiting groove 211 may be located in the middle or at both ends of either the bent portion 122 or the base cover 21.

[0041] Specifically, this limiting design ensures that the bending part 122 can accurately press against the base 2, improving the assembly accuracy and operational stability of the relay.

[0042] In one embodiment, such as Figure 5 As shown, when the limiting protrusion 123 engages with the limiting groove 211, at least a portion of the base 2 comes into contact with the bent portion 122, and the bent portion 122 presses against at least a portion of the base 2 to fix the base 2.

[0043] Specifically, this fixing method makes the installation and removal of the relay body 1 convenient while greatly improving the stability of the installation.

[0044] In one embodiment, such as Figure 7 As shown, the housing 11 has a flange 16 inside, and the flange 16 and the support 13 form an annular channel so that at least part of the base 2 can rotate in the channel. When at least part of the base 2 rotates to a predetermined position, the limiting protrusion 123 and the limiting groove 211 are engaged.

[0045] Specifically, the above structure allows for flexible installation and disassembly of the relay body 1 by using rotational fixing, while greatly reducing the relay installation size and structural cost of the relay product; the relay installation is intuitive and controllable, reducing the risk of insufficient bolt tightening torque.

[0046] In one embodiment, such as Figure 4 As shown, the base 2 is the basic component of the relay, and it has an internal cavity to accommodate the motor 22 and other related components. The motor 22 is fixed to the housing 23, and the base copper busbar 24 is fixed inside the housing 23 by injection molding. The motor 22 is connected to the base copper busbar 24 to connect to the external circuit.

[0047] Specifically, the main function of the base copper busbar 24 is to connect the motor 22 to the external circuit, enabling current transmission. Through the base copper busbar 24, the motor 22 can receive power from an external power source, providing power to the fan 25. The design of the base copper busbar 24 ensures efficient and stable current transmission, reducing energy loss and poor contact issues.

[0048] In one embodiment, such as Figure 4 As shown, the fan 25 is placed in the cavity inside the base 2, the motor shaft is fixed to the bottom of the base 2, the fan 25 is fixed to the motor shaft, and the motor 22 provides power to the fan 25 to drive the fan 25.

[0049] In one embodiment, such as Figure 3 As shown, the base cover 21 is provided with ventilation holes 212 so that the air blown by the fan 25 in the base 2 flows into the main body 1 through the ventilation holes 212.

[0050] Optionally, the base cover 21 is provided with ventilation holes 212, the size and dimensions of which are adapted to the base cover 21 to ensure that a number of ventilation holes 212 can be evenly arranged on the base cover 21.

[0051] Optionally, the ventilation holes 212 include, but are not limited to, fan-shaped, rectangular, square, and circular shapes.

[0052] Specifically, the fan 25 provides heat dissipation when the motor 22 is operating. This self-heating function significantly improves the relay's operating environment, thereby reducing component selection costs. During relay operation, the relay body 1 generates a large amount of heat, requiring timely heat dissipation. The ventilation hole 212 provides a ventilation and heat dissipation channel. When the fan 25 in the base 2 is operating, cool air moves into the relay body 1 through the ventilation hole 212, and then hot air is discharged through the threaded structure of the inner layer 31 of the sound-absorbing sheath. This effectively dissipates heat, keeping the internal temperature of the relay within a reasonable range, thereby extending the relay's service life and improving its operational stability.

[0053] In one embodiment, such as Figure 3 and Figure 4 As shown, the protrusion 26 is at least part of the base 2, facilitating access to the support portion 13 from the support portion opening 14. The size and dimensions of the first through hole 213 on the base cover 21 are adapted to the size and dimensions of the base copper busbar 24, allowing the base copper busbar 24 to pass through the first through hole 213. The base copper busbar 24 is embedded in the base 2 by injection molding. After passing through the first through hole 213, the base copper busbar 24 overlaps the protrusion 26 to contact the pressing member 12. The base copper busbar 24 is embedded in the base 2 by injection molding to prevent short circuits and leakage.

[0054] Specifically, through this design, the base copper busbar 24 not only connects the motor 22 to the external circuit, but also ensures the stability and safety of the circuit.

[0055] In one embodiment, such as Figure 5 and Figure 7 As shown, the main copper busbar 15 is fixed inside the housing 11 by injection molding and leads out from the bottom of the housing 11 for conduction. When the limiting protrusion 123 is engaged with the limiting groove 211, the main copper busbar 15 and the base copper busbar 24 will overlap, thereby realizing the circuit connection between the base 2 and the main body 1.

[0056] Specifically, this design not only ensures the stability of the mechanical connection but also guarantees the reliable connection of the circuit, thereby improving the electrical performance of the relay.

[0057] In one embodiment, such as Figure 6As shown, the sound-absorbing sleeve 3 is made of noise-reducing material and is located on the outside of the main body 1, effectively wrapping the main body 1 and reducing noise leakage. Optionally, the sound-absorbing sleeve 3 is installed on the outside of the main body 1 by adhesive or other fixing methods.

[0058] Specifically, the sound-absorbing sleeve 3 on the outside of the main body 1 can initially absorb the noise generated by the relay.

[0059] In one embodiment, such as Figure 6 As shown, the sound-absorbing sheath 3 includes an inner layer and an outer layer. The outer layer 32 of the sound-absorbing sheath is located outside the inner layer 31 of the sound-absorbing sheath, and its surface is provided with a plurality of second through holes 321. A sound-absorbing structure 322 is provided on the second through holes 321, and the sound-absorbing structure 322 connects the inner layer 31 and the outer layer 32 of the sound-absorbing sheath.

[0060] Specifically, the sound-absorbing structure 322 can effectively absorb and dissipate noise energy, reduce relay noise, and strengthen NVH control of the relay.

[0061] In one embodiment, such as Figure 6 As shown, one end of the sound-absorbing structure 322 is accommodated in the second through hole 321, while the other end contacts the outer wall of the inner layer 31 of the sound-absorbing sheath. The area of ​​the sound-absorbing structure 322 at one end of the second through hole 321 is larger than the contact area at the outer wall of the inner layer 31 of the sound-absorbing sheath.

[0062] Specifically, the above structure can further dissipate noise energy.

[0063] In one embodiment, such as Figure 6 As shown, the sound-absorbing structure 322 uses sound-absorbing material, and the inner layer 31 of the sound-absorbing sheath directly contacts the main body 1, with spiral stripes 311 on its inner side.

[0064] Optionally, the sound-absorbing material includes, but is not limited to, porous sound-absorbing materials, resonant sound-absorbing materials, and sound-absorbing materials with special structures.

[0065] Specifically, the sound-absorbing material can further enhance the noise reduction effect of the sound-absorbing structure 322; the design of the spiral stripes 311 can effectively conduct and disperse sound, reduce the reflection and resonance of sound inside the main body 1, thereby reducing the intensity of noise.

[0066] Through the above structural design, the relay in this embodiment not only achieves a stable connection and flexible installation and removal between the main body 1 and the base 2, but also effectively reduces operating noise, enhances the relay's working stability in heating environments, and improves the relay's reliability and service life. Furthermore, this relay has broad application prospects and can meet the electrical control needs of different scenarios.
