[0028] This utility model proposes a mounting and positioning structure for a capacitor and a motor.
[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0030] In embodiments of this utility model, such as Figures 1 to 5As shown, the capacitor and motor mounting and positioning structure 100 includes a motor housing 10 and a capacitor housing 20. The motor housing 10 has a positioning part 11 and a mounting part 12. There are two mounting parts 12 located on opposite sides of the positioning part 11. The positioning part 11 has two positioning grooves 111 and two protruding holes 112 at its top to correspond to the two positioning grooves 111 respectively. The capacitor housing 20 has a housing part 21. The bottom of the housing part 21 has a mounting plate 22 and the side of the housing part 21 has two positioning posts 23. The two positioning posts 23 extend into the two positioning grooves 111 respectively. The top of the positioning posts 23 extends out of the positioning part 11 through the protruding holes 112. The top end face of the mounting plate 22 abuts against the bottom end face of the mounting part 12 and is fixed by threaded fasteners.
[0031] The capacitor of this utility model specifically includes a capacitor housing 20, a capacitor core, and leads. The housing portion 21 of the capacitor housing 20 has a receiving cavity with a top opening. There are two leads that are welded to opposite sides of the capacitor core to form a core component. The core component is placed inside the receiving cavity. The two leads extend out of the housing portion 21 from the top opening. The core component and the housing portion 21 are encapsulated with epoxy resin. The leads of the capacitor of this utility model are connected to the circuit module of the motor through electrical connection wires.
[0032] In this utility model, the side and bottom of the positioning part 11 are provided with openings to facilitate the positioning post 23 to penetrate into the positioning groove 111. The size of the positioning groove 111 is larger than the outer size of the positioning post 23. The shape of the protrusion hole 112 is adapted to the shape of the top of the positioning post 23 to better achieve the positioning effect.
[0033] During assembly, the side of the capacitor housing 20 with the positioning pins 23 facing the positioning part 11 is opened. The capacitor housing 20 is moved closer to the positioning part 11 so that the two positioning pins 23 enter the two positioning grooves 111 respectively. The capacitor housing 20 is then moved upward, that is, the top of the positioning pins 23 is moved closer to the protrusion hole 112. When it moves upward until the top end face of the mounting plate 22 abuts against the bottom end face of the mounting part 12, positioning is achieved. At the same time, the top of the positioning pins 23 also protrudes from the protrusion hole 112. At this point, the positioning of the motor housing 10 and the capacitor housing 20 is completed. Both the mounting plate 22 and the mounting part 12 have mounting holes. Specifically, the mounting hole in the mounting part 12 can be a threaded hole and the mounting hole in the mounting plate 22 can be a through hole, or the mounting hole in the mounting part 12 can be a through hole and the mounting hole in the mounting plate 22 can be a threaded hole. The threaded fastener passes through the through hole and is threadedly connected to the threaded hole, thereby realizing the installation and fixation of the motor housing 10 and the capacitor housing 20.
[0034] This utility model uses a combination of positioning structure and threaded fasteners to achieve the positioning and installation of capacitors, which can ensure high positioning accuracy and the assembled capacitors are not prone to positional displacement, and will not affect the assembly of other components.
[0035] This utility model includes a motor housing 10 and a capacitor housing 20. The motor housing 10 is provided with a positioning part 11 and a mounting part 12. The positioning part 11 is provided with a positioning groove 111. The capacitor housing 20 is provided with a positioning post 23 corresponding to the positioning groove 111 and a mounting plate 22 corresponding to the mounting part 12. By adopting the technical means of positioning by the positioning post 23 cooperating with the positioning groove 111 and fixing the mounting plate 22 to the mounting part 12, the problem of misalignment and other problems affecting assembly caused by single screw fixing in the prior art is effectively solved, thereby achieving the technical effect of high positioning accuracy and stable installation.
[0036] In embodiments of this utility model, such as Figure 4 As shown, the positioning post 23 includes a connecting part 231 and a post body 232 connected together. The connecting part 231 is located on the side of the housing part 21, and the post body 232 is located on the top of the connecting part 231. The bottom of the connecting part 231 extends downward and connects to the mounting plate 22. The shape of the post body 232 is adapted to the shape of the protruding hole 112. The connection between the connecting part 231 and the mounting plate 22 can improve the stability of the overall structure. The connection between the post body 232 and the connecting part 231 is achieved by a rounded transition.
[0037] In embodiments of this utility model, such as Figure 4 As shown, the side of the column 232 away from the housing part 21 is a flat surface, and the side of the column 232 facing the housing part 21 is an arc surface. The combination of the flat and arc surfaces improves positioning accuracy and reduces capacitor sway on the horizontal plane, thus facilitating the installation of threaded fasteners. The column 232 of this invention has a quadrangular prism structure. The flat surface and the arc surface of the column 232 transition through two side planes. The flat surfaces on opposite sides of the column 232 are flush with the two side planes, and the flat surface of the column 232 facing the positioning part 11 is also flush with the flat surface of the column 232.
[0038] In embodiments of this utility model, such as Figure 4 As shown, the movable end of the column 232 is chamfered. Specifically, the movable end of the column 232 is the section away from the connecting part 231. The chamfer serves as a guide, facilitating the extension of the column 232 from the position of the extension hole 112.
[0039] In embodiments of this utility model, such as Figure 3 and Figure 4As shown, the motor housing 10 is also provided with a positioning cylinder 13, which is located near the mounting portion 12. The mounting plate 22 is also provided with a positioning hole 221 corresponding to the positioning cylinder 13. The way the positioning cylinder 13 and the mounting plate 22 cooperate can further improve the positioning accuracy and reduce shaking.
[0040] In embodiments of this utility model, such as Figure 3 As shown, the movable end of the positioning cylinder 13 is chamfered. Specifically, the movable end of the positioning cylinder 13 is the end away from the motor housing 10. The chamfer serves as a guide, facilitating the extension of the positioning cylinder 13 from the positioning hole 221.
[0041] In embodiments of this utility model, such as Figure 1 As shown, the side of the positioning part 11 abuts against the side of the housing part 21, and the bottom end face of the positioning part 11 abuts against the top end face of the mounting plate 22. This planar contact in both the horizontal and vertical directions further improves positioning accuracy.
[0042] In embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the capacitor housing 20 is also provided with a wire harness bracket 24, which has a wire harness groove for accommodating wires.
[0043] Understandably, the capacitor and the motor's circuit module are electrically connected via electrical connecting wires, and the motor's circuit module is also electrically connected to other electrical components via wires. Different wires are prone to tangling and knotting. Therefore, this invention provides a wire harness bracket 24 on the capacitor housing 20 for storing wires. Specifically, the wire harness bracket 24 is used to store the electrical connecting wires between the circuit module and the capacitor. The wire harness bracket 24 is hook-shaped and has a wire passage opening and a wire harness groove connecting to the wire passage opening. The electrical connecting wire passes through the wire passage opening and is accommodated inside the wire harness groove. The wire harness bracket 24 of this invention is located on the side of the housing 21 away from the positioning post 23.
[0044] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
