Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to an electrical component bracket, a distribution box, and an air conditioning system. Background Technology

[0002] In the current air conditioning industry, in order to improve product versatility, the specifications of electrical components (such as circuit breakers, contactors, and relays) are often standardized. Therefore, the brackets for electrical components are often guide rail type brackets. These brackets meet the width requirements of different specifications of circuit breakers. However, when installing such electrical component brackets, the guide rail type brackets must first be cut according to the specifications of the electrical components, then the guide rail type brackets are fastened to the mounting plate with screws, then the electrical components are installed, and finally two stops are needed to limit the circuit breaker. The process is complicated and time-consuming. Summary of the Invention

[0005] Base plate;

[0006] The first side plate is erected at one end of the base plate along the longitudinal direction of the base plate, and the first side plate is provided with a first blocking structure with a first blocking protrusion blocking the electrical components.

The second side plate is provided with a second blocking structure for blocking electrical components, and the second blocking protrusion is arranged opposite to the first blocking protrusion.

[0008] Two limiting components are connected to the base plate and arranged laterally intersecting the longitudinal direction. The spacing between the two limiting components is adapted to the size of the electrical components to restrict the lateral movement of the electrical components.

[0009] In some embodiments, the limiting member is disposed at the end of the first side plate away from the bottom plate along the thickness direction of the bottom plate, and protrudes from the first side plate along the thickness direction of the bottom plate.

[0014] In some embodiments, the first side plate, the limiting member, and the first locking structure are constituted by a first plate-shaped member connected to the bottom plate. The middle portion of the first plate-shaped member at one end away from the bottom plate is bent in a direction away from the second side plate to form the first locking structure. The unbent portions at both ends of the first plate-shaped member in the lateral direction form two limiting members.

[0018] In some embodiments, a first positioning structure is provided on the side of the first base plate away from the first side plate and the second side plate for mounting the mounting substrate that supports the electrical components.

[0019] In some embodiments, the first positioning structure is configured to have a foolproof function.

[0020] In some embodiments, the first positioning structure is an asymmetric structure.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Figures 1 to 3 A schematic diagram of the electrical component mounting mechanism inside the distribution box according to an embodiment of the present invention is shown, in conjunction with... Figures 1 to 3 As shown in Figure 11, the distribution box includes a box body and a mounting base plate 1 disposed inside the box body. An electrical component bracket 2 is mounted on the mounting base plate 1, and an electrical component 3 is snapped onto the electrical component bracket 2.

[0040] To simplify the installation process of electrical components and reduce installation time, this embodiment provides an electrical component bracket, combined with... Figures 4 to 8 As shown, the electrical component bracket 2 includes a base plate 21, a first side plate 28, a second side plate 27, and two limiting components 24.

[0041] The first side plate 28 is erected at one end of the base plate 21 along the longitudinal direction of the base plate 21, and the first side plate 28 is provided with a first blocking structure 23 of the first blocking protrusion 341 of the first blocking electrical component 3.

[0042] The second side plate 27 is erected on the other end of the base plate 21 along the longitudinal direction and is erected on the same side of the base plate 21 as the first side plate 28. The second side plate 27 is provided with a second blocking structure 22 for the second blocking protrusion 33 of the second blocking electrical component 3. The second blocking protrusion 33 is arranged opposite to the first blocking protrusion 341.

[0043] Two limiting components 24 are connected to the base plate 21 and arranged in a transverse direction intersecting the longitudinal direction. The spacing between the two limiting components 24 is adapted to the size of the electrical component 21 to restrict the electrical component 3 from moving laterally.

[0044] The electrical component bracket of this embodiment includes a limiting component 24 that restricts the movement of the electrical component 3. Compared with the technical solution of installing the electrical component 3 on the guide rail and then installing limiters connected to the guide rail on both sides of the electrical component 3 to restrict the movement of the electrical component 3 along the guide rail, this embodiment is beneficial to simplify the installation process of the electrical component 3 and reduce the installation time.

[0045] In some embodiments, the spacing between the two limiting components 24 is adapted to the size of only one type of electrical component 3. Each electrical component bracket 2 is equipped with a fixed type and model of electrical component 3, and each electrical component 3 corresponds to a specific electrical component bracket 2, which helps to improve installation efficiency and matching accuracy.

[0046] The first side plate 28 is arranged along the edge extending laterally at one end of the longitudinal direction of the base plate 21, and the second side plate 27 is arranged along the edge extending laterally at the other end of the longitudinal direction of the base plate 21.

[0047] The limiting member 24 is located at the end of the first side plate 28 away from the base plate 21 along the thickness direction of the base plate 21, and protrudes from the first side plate 28 along the thickness direction of the base plate 21. A notch for accommodating the electrical component 3 is formed between the two limiting members 24. After the electrical component 3 is installed on the electrical component bracket 2, it is restricted to move laterally by the two limiting members 24.

[0048] The limiting component 24 and the first side plate 28 are integrally formed, which helps to simplify the structure of the electrical component bracket 2, reduce production costs, and improve production efficiency. Optionally, the limiting component 24 and the first side plate 28 can be integrally stamped.

[0049] The first blocking structure 23 includes a first baffle plate disposed on the side of the first side plate 28 away from the second side plate 27. The first baffle plate and the base plate 21 are spaced apart in the thickness direction of the base plate 21. The first baffle plate is erected at the end of the first side plate 28 away from the base plate 21 in the thickness direction of the base plate 21, and the first baffle plate is located on the side of the first side plate 28 opposite to the first side plate 27.

[0050] like Figures 2 to 3 As shown in Figures 9 and 10, in this embodiment, the electrical component 3 includes an electrical component body 31, a mounting groove 32 on the back of the electrical component body 31, a first snap-fit ​​protrusion 341 on one side of the mounting groove 32, and a second snap-fit ​​protrusion 33 on the other side of the mounting groove 32. The first snap-fit ​​protrusion 341 and the second snap-fit ​​protrusion 33 are arranged opposite to each other and are spaced apart from the bottom surface of the mounting groove 32. The mounting groove 32 includes a bottom surface and two side surfaces on both sides of the bottom surface. The first snap-fit ​​protrusion 341 and the second snap-fit ​​protrusion 33 are respectively located on the two side surfaces of the mounting groove. The first locking structure 23 is engaged between the first snap-fit ​​protrusion 341 and the bottom surface of the mounting groove 32.

[0051] In some embodiments, as shown in the figure, electrical component 3 includes a latch 34 movably mounted on electrical component body 31. A first latching protrusion 341 is formed at one end of the latch 34. The latch 34 moves relative to the electrical component body 31 to switch between a position protruding from the side of the mounting 32 and a position not protruding from the side of the mounting groove 32. The other end of the latch 34 is provided with a pull portion 342, which can pull the first latching protrusion 341 to a position protruding from the side of the mounting groove 3, so as to facilitate mounting the electrical component 3 on the electrical component bracket 2. When the electrical component 3 is mounted on the electrical component bracket 2, the pull portion 342 of the latch 34 is released. The first latching protrusion 341 moves towards the side of the mounting groove 32 under the push of the elastic member, thereby fixing the first locking structure 23 between the first latching protrusion 341 and the bottom surface of the mounting groove 32.

[0052] In some embodiments, the first retaining structure 23 and the first side plate 28 are integrally formed, which helps to simplify the structure of the electrical component bracket 2, reduce production costs, and improve production efficiency. Optionally, the first retaining structure 23 and the first side plate 28 can be integrally stamped.

[0053] The first side plate 28, the limiting component 24, and the first clamping structure 23 are integrally formed to simplify the structure of the electrical component bracket 2, reduce production costs, and improve production efficiency.

[0054] The first side plate 28, the limiting component 24, and the first blocking structure 23 are composed of a first plate-shaped component connected to the bottom plate 21. The middle part of the first plate-shaped component at one end away from the bottom plate 21 is bent in the direction away from the second side plate 27 to form the first blocking structure 23. The unbent parts at both ends of the first plate-shaped component in the horizontal direction form two limiting components 24.

[0055] In some embodiments, the electrical component bracket 2 is integrally formed, which simplifies the structure of the electrical component bracket 2, reduces production costs, and improves production efficiency.

[0056] The second locking structure 22 includes a locking groove formed on the side of the second side plate 27 away from the first side plate 28.

[0057] Compared to the baffle provided on the side of the second side plate 27 opposite to the first side plate 28, which limits the second snap-fit ​​protrusion 33 between the bottom surface of the mounting groove 32 and the baffle, the travel of the first snap-fit ​​protrusion 341 inward retraction into the side of the mounting groove 32 to avoid the first snap-fit ​​structure 23 can be effectively reduced. Thus, the length of the first snap-fit ​​protrusion 341 can be designed to be higher to ensure the firmness of the connection between the electrical component 3 and the electrical component bracket 2.

[0058] The electrical component bracket also includes a second baffle 25 disposed on the second side plate 27 at one end away from the base plate 21 along the thickness direction of the base plate 21, the second baffle 25 being located on the side of the second side plate 25 adjacent to the first side plate 28.

[0059] The edge of the slot on the side away from the base plate 21 along the thickness direction of the base plate 21 is flush with the surface of the second baffle 25 on the side near the base plate 21. The first snap-fit ​​protrusion 33 is inserted into the slot, and the first baffle 25 is located between the second snap-fit ​​protrusion 33 and the bottom surface of the mounting groove 32. The first baffle 25 can effectively increase the contact area with the second snap-fit ​​protrusion 33 to improve the bonding strength after snap-fit. On the other hand, setting the slot as close to the outer side as possible also helps to reduce the depth of the mounting groove.

[0060] A first positioning structure 26 is provided on the side of the first base plate 21 away from the first side plate 28 and the second side plate 27 to position the mounting base plate 1 that supports the electrical component bracket 2, thereby quickly positioning the installation position and improving installation efficiency. Figure 2 As shown, the mounting base 1 is provided with a second positioning structure 11 corresponding to the first positioning structure 26. One of the first positioning structure 26 and the second positioning structure 11 is a positioning protrusion, and the other is a positioning groove adapted to the positioning protrusion. When the electrical component 3 is installed on the mounting base 1, the positioning protrusion and the positioning groove are aligned, and the electrical component 3 is in the predetermined installation position, which helps to improve installation efficiency.

[0061] The first positioning structure 26 is configured to have a foolproof function, which helps to avoid misaligning the electrical component bracket 2.

[0062] The first positioning structure 26 is an asymmetric structure to achieve the above-mentioned error prevention function. The first positioning structure 26 is at least one of non-linear symmetry, non-central symmetry, and non-rotational symmetry.

[0063] Specifically, in this embodiment, the mounting base plate 1 is a sheet metal part with a large flat surface. Its function is to provide a mounting surface for the electrical component bracket 2. The second positioning structure 11 is asymmetrically divided on the mounting base plate 1, and its main function is to position and prevent reverse installation.

[0064] The main function of the electrical component bracket 2 is to mount (e.g., by spot welding, threaded connection) the component onto the mounting base plate 1, and then mount the electrical component 3 (e.g., a circuit breaker) onto the electrical component bracket 2. The electrical component bracket 2 is provided with two limiting members 24, which restrict the left and right movement of the circuit breaker. The distance between the two limiting members 24 is A, and the height is B, where 10mm > B > 7mm. (See [reference needed]). Figure 7 .

[0065] The second baffle 25 serves to support the electrical component 3. The slot (which can be a through hole) allows the first snap-fit ​​protrusion 33 (wedge-shaped buckle) of the electrical component 3 to enter. The base plate 21 of the electrical component bracket contacts the surface of the mounting base plate 1 during installation. The base plate 21 is provided with multiple positioning protrusions, the number and distribution of which are consistent with the positioning grooves (which can be through holes) of the mounting base plate 1. They mainly serve to position and prevent reverse installation.

[0066] The first baffle and the second baffle 25 are at the same height, and both serve to support the electrical components. During installation, the first snap-fit ​​protrusion 341 of the electrical component 3 is installed on the first baffle. The distance D between the slot 22 and the end of the first baffle (first snap-fit ​​structure 23) furthest from the first side plate 28 is [see section 1]. Figure 6 .

[0067] Electrical component 3 includes a first snap-fit ​​protrusion 341 and a second snap-fit ​​protrusion 33. The width of electrical component 3 is C. The value of C varies for different specifications of circuit breakers. When selecting the electrical component bracket, the following conditions must be met: 2mm > AC > 1mm. The distance between the bottom end of the first snap-fit ​​protrusion 341 and the bottom end of the second snap-fit ​​protrusion 33 is E, which satisfies D = E + 0.5. This interference fit enhances the stability of the electrical component.

[0068] The installation process for electrical component 3 is as follows: Before installing electrical component 3, the electrical component mounting plate assembly (such as...) must be provided. Figure 11 The mounting plate assembly includes a mounting base 1 and an electrical component bracket 2. The electrical component mounting plate assembly is mainly positioned by the second positioning structure 11 and the first positioning structure 26, and then spot-welded together. Before installing the electrical component, the clip 34 needs to be pulled open. During the installation of the electrical component, the second snap-fit ​​protrusion 33 is inserted into the slot, and then the electrical component is pressed tightly against the electrical component bracket 2. Finally, the second snap-fit ​​protrusion 34 is pushed between the bottom surface of the first snap-fit ​​structure 23 and the mounting groove 32, at which point the installation of the electrical component is completed. That is, the installation of the electrical component can be completed by pulling, snapping, and pushing.

[0069] According to another aspect of the present invention, a distribution box is also provided, which includes the above-described electrical component support 2 and a mounting base plate 1 for supporting the electrical component support 2.

[0070] In some embodiments, the mounting base 1 is welded to the electrical component bracket 2. In some embodiments, the mounting base 1 and the electrical component bracket 2 are connected by a threaded connector. The first positioning structure 26 is a through hole, and the second positioning structure 11 is a threaded hole. The threaded connector connecting the mounting base 1 and the electrical component bracket 2 passes through the aforementioned through hole and is screwed into the threaded hole.

[0071] According to another aspect of the present invention, an air conditioning system is also provided, the air conditioning system including the aforementioned distribution box.

[0072] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
