[0028] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0029] See Figure 1 and Figure 2 This embodiment discloses a relay structure, which includes a base 1, a frame 2, an electromagnetic component, a push plate 3, a moving contact component, and a stationary contact component. The electromagnetic component is disposed on the frame 2. The frame 2, the moving contact component, and the stationary contact component are all mounted on the base 1. The push plate 3 is slidably disposed on the top of the base 1. Specifically, push plate slide rails 31 are respectively provided on both sides of the push plate 3, and slide rail steps 14 are respectively provided on both sides of the upper part of the base 1. The push plate slide rails 31 and the slide rail steps 14 slide in cooperation. The slide rail steps 14 support the push plate slide rails 31, so that the reciprocating motion of the push plate 3 is more precise and controlled. The push plate 3 is connected between the armature in the electromagnetic component and the moving spring in the moving contact component. When the armature moves, the push plate 3 can drive the moving contact component and the stationary contact component to be connected or disconnected.

[0030] Based on the principle of full disclosure, as an optional example of an electromagnetic component, a moving contact component, and a stationary contact component, the electromagnetic component includes a coil, a U-shaped yoke, an armature, and a reset spring. One side arm of the U-shaped yoke passes through the frame 2, and the coil is wound on the frame 2. One end of the armature is rotatably connected to one side arm of the U-shaped yoke, and the other end of the armature is attracted to the end face of the other side arm of the U-shaped yoke. The reset spring is connected to the armature and the yoke, and provides elastic force to drive the armature to rotate, causing the other end of the armature to separate from the end face of the other side arm of the U-shaped yoke. The moving contact component includes a moving contact and a moving spring. The moving contact is located at one end of the moving spring, and the other end of the moving spring is fixed to the base 1. The stationary contact component includes a stationary contact and a stationary spring. The stationary contact is located at one end of the stationary spring, and the other end of the stationary spring is fixed to the base 1. The moving contact and the stationary contact are positioned opposite each other. In use, the rotation of the armature can drive the push plate 3 to slide, and the sliding push plate 3 can drive the moving spring, thereby making the moving contact and the stationary contact connect or disconnect.

[0031] See Figures 2 to 4 In this embodiment, the base 1 is provided with a first guide part 11 and a first positioning locking part 12, and the frame 2 is provided with a second guide part 21 and a second positioning locking part 22. The first guide part 11 and the second guide part 21 slide to guide the frame 2 on the base 1, and the first positioning locking part 12 and the second positioning locking part 22 engage to fix the frame 2 on the base 1.

[0032] In the above scheme, during assembly, the second guide part 21 of the skeleton 2 cooperates with the first guide part 11 of the base 1 to play a guiding role, thereby facilitating the insertion of the skeleton 2 into the base 1. After the skeleton 2 is inserted into place, the skeleton 2 can be positioned and locked on the base 1 by the cooperation of the first positioning locking part 12 and the second positioning locking part 22. This facilitates installation and ensures accurate positioning, thereby improving production efficiency and assembly accuracy.

[0033] To facilitate the installation and isolation of the frame 2 on the base 1, the base 1 has a receiving cavity 13 with one end open. The frame 2 is inserted into the receiving cavity 13 along the open end of the receiving cavity 13. During the insertion process, the second guide part 21 at the bottom of the frame 2 cooperates with the first guide part 11 at the bottom of the base 1 to play a guiding role. At the same time as this process, the first positioning locking part 12 and the second positioning locking part 22 also cooperate.

[0034] The preferred number of each guide part and each positioning locking part is two. Specifically, there are two first guide parts 11 and two second guide parts 21. The two first guide parts 11 are spaced apart and arranged in parallel, with each first guide part 11 adjacent to one side wall of the opening end of the receiving cavity 13. Similarly, the two second guide parts 21 are spaced apart and arranged in parallel, with each first guide part 11 cooperating with one second guide part 21. There are two first positioning locking parts 12 and two second positioning locking parts 22. The two first positioning locking parts 12 are arranged opposite each other on two opposite side walls of the opening end of the receiving cavity 13, and the two second positioning locking parts 22 are arranged opposite each other on two opposite outer sides of the frame 2. This allows for more precise and stable installation of the frame 2 on the base 1.

[0035] Since the first positioning and locking part 12 is provided on the side wall of the accommodating cavity 13, in order to avoid affecting the sliding of the skeleton 2 on the base 1 before locking, in this embodiment, the base 1 is made of plastic material, and the two opposite side walls at the opening end of the accommodating cavity 13 can be elastically deformed. In this way, the elastic deformation of the two opposite side walls can form an avoidance effect, so as not to affect the sliding of the skeleton 2 on the base 1.

[0036] In this embodiment, preferably, the second positioning and locking part 22 includes a locking block 600, and the first positioning and locking part 12 includes a locking hole 500 and a sliding groove 501. The locking hole 500 and the sliding groove 501 are jointly disposed on the same wall surface of the accommodating cavity 13. The sliding groove 501 is located on the path along which the locking block 600 and the locking hole 500 cooperate. Specifically, one end of the sliding groove 501 in the length direction extends to the end face of the opening end of the accommodating cavity 13, and the other end of the sliding groove 501 in the length direction is connected to the locking hole 500. The locking block 600 is provided with a second guide slope 601. The second guide slope 601 slides against the front end of the bottom wall of the sliding groove 501 to open the two opposite side walls of the opening end of the accommodating cavity 13 until the locking block 600 is embedded in the locking hole 500 to complete the locking.

[0037] According to the above locking mechanism, the locking block 600 and the locking hole 500 are two parts of the two-phase fitting limiting device. Therefore, the locking hole 500 and the locking block 600, which are respectively located on the inner wall of the base 1 and the outer wall of the frame 2, can be interchanged. Correspondingly, the slide groove 501, along with the locking hole 500, is changed from the inner wall of the base 1 to the corresponding position on the outer wall of the frame 2. The direction of the slide groove 501 is opposite to the original direction. The second guide slope 601 is changed from the front of the original locking block 600 to the rear of the locking block 600 to adapt to the new fitting relationship.

[0038] In the above scheme, the slide groove 501 serves two purposes: First, it restricts the vertical displacement of the skeleton and guides the locking block 600 to the locking hole 500 for easy locking. The added second guide slope 601 can also better guide the locking block 600 into the slide groove 501. Second, the depth of the slide groove 501 can provide some clearance space, thereby reducing the deformation of the base 1 and the skeleton 2 during the fitting process. The two opposite sidewalls of the accommodating cavity 13 do not need excessive elastic deformation, thus avoiding material fatigue and performance instability.

[0039] In this embodiment, the first guide portion 11 includes a bottom slot 502 penetrating the bottom wall of the receiving cavity 13, and the second guide portion 21 includes a bottom protrusion 602 disposed on the bottom surface of the outer end of the frame 2. The front end of the bottom protrusion 602 is provided with a first guide slope 603, which is used to guide the bottom protrusion 602 to slide into the bottom slot 502. By setting the bottom slot 502 on the bottom wall of the base 1 and the bottom protrusion 602 on the bottom of the frame 2, it not only serves as a guide, but the bottom slot 502 also disconnects the connection between the side wall of the opening end of the base 1 and the bottom surface, improving the lateral elastic deformation capability of this side wall. This facilitates the bottom wall of the slide groove 501 to lift the locking block 600 together with this side wall until the locking block 600 slides into the locking hole 500 to complete the locking engagement.

[0040] The foregoing has provided a detailed description of a relay structure for easy assembly and positioning disclosed in the embodiments of this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the fresh air module and fresh air air conditioner of this utility model and their core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
