[0063] Example
[0064] Figure 1 Schematic diagram of the structure of the air compressor 1 in one embodiment of the present application; Figure 2 for Figure 1 A cross-sectional view of the capacitor assembly 1000 in the illustrated embodiment; Figure 3 for Figure 1 A cross-sectional view of the mounting structure 100 in the illustrated embodiment.
[0065] See also Figure 1 , an embodiment of the present application provides an air compressor 1, including a capacitor assembly 1000 and an air storage tank 2000.
[0066] See also Figure 2 and Figure 3 The capacitor assembly 1000 includes a mounting structure 100 and a capacitor 200. The mounting structure 100 includes a fixing bracket 10 and a box body 20. The fixing bracket 10 is arranged on the outside of the gas tank 2000. The box body 20 is installed on the fixing bracket 10 and has a accommodating cavity 20a. The capacitor 200 is arranged in the accommodating cavity 20a.
[0067] During use, the fixing bracket 10 is first fixed to the outside of the gas tank 2000, the capacitor 200 is then installed in the accommodating cavity 20a, and the box body 20 is then assembled to the fixing bracket 10. In this way, the box body 20 is fixed relative to the fixing bracket 10, and the capacitor 200 is installed on the outside of the gas tank 2000 through the mounting structure 100.
[0068] Figure 4 for Figure 1 A schematic structural diagram of the box body 20 in the illustrated embodiment in an open state; Figure 5 for Figure 1 A cross-sectional view of the box body 20 in the illustrated embodiment in a closed state; Figure 6 for Figure 1 The box body 20 and the fixing bracket 10 in the embodiment shown are schematically shown in exploded state.
[0069] See also Figures 2 to 4 This embodiment provides a mounting structure 100 for mounting a capacitor 200 . The mounting structure 100 includes a box body 20 and a fixing bracket 10 .
[0070] The box body 20 includes a first half shell 21 and a second half shell 22. The first half shell 21 defines an open first receiving groove 21a, and the second half shell 22 defines an open second receiving groove 22a. The first half shell 21 has a first side 2111 and a second side 2112 that are opposite to each other in the circumferential direction. The second half shell 22 has a third side 2211 and a fourth side 2212 that are opposite to each other in the circumferential direction. The second side 2112 is provided with a first docking portion 212, and the first docking portion 212 is provided with a first docking hole 212a. The fourth side 2212 is provided with a second docking portion 222, and the second docking portion 222 is provided with a second docking hole 222a. The first side 2111 and the third side 2211 are rotatably connected to each other so that the first half shell 21 and the second half shell 22 can rotate relative to each other to a closed state or an open state. Figure 3 and Figure 5 As shown, in the closed state, the second side 2112 and the fourth side 2212 are close to each other, the first docking portion 212 and the second docking portion 222 are stacked in the thickness direction, and the first docking hole 212a is connected to the second docking hole 222a, and the first receiving groove 21a is connected to the second receiving groove 22a to form an accommodating cavity 20a, which is used to install the capacitor 200. Figure 6 As shown, the fixing bracket 10 includes a clamping portion 11. In the closed state, the clamping portion 11 is clamped and matched with the first docking hole 212a and the second docking hole 222a.
[0071] During assembly of the mounting structure 100, in the open state, the capacitor 200 is placed in the first receiving groove 21a or the second receiving groove 22a. The first half shell 21 and the second half shell 22 are then rotated relative to each other to switch to the closed state, thereby accommodating the capacitor 200 in the receiving cavity 20a. Furthermore, in the closed state, the first docking portion 212 and the second docking portion 222 are stacked along the thickness direction, and the first docking hole 212a is connected to the second docking hole 222a, allowing the engaging portion 11 to engage with the first docking hole 212a and the second docking hole 222a, thereby securing the box body 20 relative to the fixing bracket 10 and completing the installation of the capacitor 200. During the assembly process, the capacitor 200 is confined within the box body 20 by relatively rotating the first half shell 21 and the second half shell 22 to a closed state, and the box body 20 and the clamping portion 11 are assembled and fixed, without the need to use fasteners to assemble the capacitor 200 to the box body 20 or to assemble the box body 20 to the fixing bracket 10. This makes assembly of the capacitor 200 more convenient. Furthermore, the mounting structure 100 has a simple structure, which helps save costs.
[0072] In some embodiments, the connection between the first side 2111 and the third side 2211 is made of an elastic material. This allows an elastic force to be exerted between the first half shell 21 and the second half shell 22, causing them to open relative to each other in the closed state. This allows the first half shell 21 and the second half shell 22 to be more reliably engaged with the clamping portion 11 under the action of the elastic force, making it difficult for the case body 20 to fall off the clamping portion 11, thereby improving the assembly reliability of the capacitor 200. When assembling the case body 20 with the fixing bracket 10, the first half shell 21 and the second half shell 22 can be pressed on the outside to rotate the first half shell 21 and the second half shell 22 inward relative to each other to switch from the open state to the closed state, and then the clamping portion 11 can be passed through the first docking hole 212a and the second docking hole 222a. When disassembling the case body 20 from the fixing bracket 10, the first half shell 21 and the second half shell 22 can be pressed on the outside to remove the case body 20 from the clamping portion 11.
[0073] Optionally, the first half shell 21 and the second half shell 22 are both made of plastic to avoid the risk of electrical conduction when the capacitor 200 leaks.
[0074] In some embodiments, combined Figure 4 and Figure 6As shown, the clamping portion 11 is provided with a clamping slot 11a on one side near the first half shell 21 and on the other side near the second half shell 22. The first docking portion 212 is clamped against the clamping slot 11a on the side near the second half shell 22, and the second docking portion 222 is clamped against the clamping slot 11a on the side near the first half shell 21, to ensure that the box body 20 does not shift relative to the fixing bracket 10. During assembly, the outer sides of the first and second half shells 21, 22 are pressed to close the box body 20. The clamping portion 11 is then inserted into the first and second docking holes 212a, 222a until the first and second docking portions 212, 222 are circumferentially aligned with the clamping slot 11a. The pressure on the first and second half shells 21, 22 is then released, allowing the first and second half shells 21, 22 to be released outwards under the action of elastic force and then to be clamped against the two clamping slots 11a, respectively. It should be noted that when the first docking portion 212 and the second docking portion 222 are respectively locked in the two slots 11a, there is a certain gap between the second side 2112 and the fourth side 2212. Since the overall size of the installation structure 100 is small, the size of the gap is small.
[0075] In some embodiments, as Figure 4 As shown, the first half-shell 21 includes a first curved plate 211 and two first end plates 213, while the second half-shell 22 includes a second curved plate 221 and two second end plates 223. The first side 2111 and the second side 2112 are the arcuate edges of the first curved plate 211, and the two first end plates 213 are located at the axial ends of the first curved plate 211. The third side 2211 and the fourth side 2212 are the arcuate edges of the second curved plate 221, and the two second end plates 223 are located at the axial ends of the second curved plate 221. The two second end plates 223 correspond one-to-one with the two first end plates 213. In the closed state, the first curved plate 211 and the second curved plate 221 form a cylindrical structure, and the first end plates 213 and the corresponding second end plates 223 form a circular plate-like structure. In this way, the shape of the accommodating cavity 20a in the closed state is easily adapted to the shape of the capacitor 200, and the structures of the first half shell 21 and the second half shell 22 are simplified, saving materials.
[0076] In some embodiments, as Figure 4As shown, the first docking portion 212 includes a first portion 2121 and a second portion 2122 connected to each other. The first portion 2121 is embedded in the first curved plate 211, and the second portion 2122 protrudes from the first curved plate 211 toward the side close to the second curved plate 221. The first docking hole 212a passes through the first portion 2121 and the second portion 2122 respectively. The second docking portion 222 includes a third portion 2223 and a fourth portion 2224 connected to each other. The third portion 2223 is embedded in the second curved plate 221, and the fourth portion 2224 protrudes from the second curved plate 221 toward the side close to the first curved plate 211. The second docking hole 222a passes through the third portion 2223 and the fourth portion 2224 respectively. In this way, it is easy to stack the first docking portion 212 and the second docking portion 222 in the closed state, thereby facilitating the connection with the clamping portion 11 (see Figure 3 ) assembly and make the assembled structure stable.
[0077] In some embodiments, as Figure 3 and Figure 4 As shown, the number of the first docking portion 212, the second docking portion 222 and the clamping portion 11 are all two. The two first docking portions 212 are respectively arranged close to the two ends of the first half shell 21 along the axial direction, and the two second docking portions 222 are respectively arranged close to the two ends of the second half shell 22 along the axial direction. Figure 6 As shown, the fixing bracket 10 further includes a fixing plate 12. Two clamping portions 11 are provided at either end of the fixing plate 12 along the axial direction of the box body 20. The two clamping portions 11 protrude from the side of the fixing plate 12 closest to the box body 20. In this manner, both ends of the fixing bracket 10 are clamped to the box body 20 via the clamping portions 11, further improving the assembly reliability of the box body 20 and the fixing bracket 10. Furthermore, a larger space is provided between the two clamping portions 11 to accommodate the capacitor 200. Optionally, the fixing plate 12 is fixed to the outside of the gas tank 2000.
[0078] In some embodiments, as Figure 6 As shown, the first side 2111 (see Figure 4 ) is provided with a first connecting rib 214 on the outer side, and a second connecting rib (not shown in the figure) is provided on the outer side of the third side 2211. The second connecting rib is connected to the first connecting rib 214 to ensure that the first side 2111 and the third side 2211 are reliably connected and that the connection between the first side 2111 and the third side 2211 is prone to elastic deformation.
[0079] In some embodiments, combined Figure 4 and Figure 6 As shown, the first connecting rib 214 extends from one end of the first side 2111 to the other end along the axial direction of the box body 20, and the second connecting rib extends from one end of the third side 2211 to the other end along the axial direction of the box body 20 to further improve the connection reliability of the first side 2111 and the third side 2211.
[0080] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent replacements of the technical solutions of the present application should not depart from the spirit and scope of the technical solutions of the present application.
