[0006] The support plate is connected to the rotor of the motor, and the top surface of the support plate is provided with a lifting groove, the inner bottom surface of which is an axially spirally extending lifting surface.

[0007] The lifting member is connected to the housing in a non-reverse connection and passes through the shaft hole. The side of the lifting member facing the support plate protrudes to form a protrusion that matches the lifting groove. The lifting member can move up and down between the first position and the second position of the housing under the driving force of the motor and gravity.

[0008] When the protrusion is in the first position, the protrusion is inserted into the lifting groove and contacts the lifting surface;

[0009] When the protrusion is in the second position, the bottom surface of the protrusion contacts the top surface of the support plate.

[0010] Compared with the prior art, the above-described technical solution conceived in this application, by setting a lifting groove with a lifting surface on the support plate, utilizes the thickness of the support plate to achieve the lifting adjustment of the lifting component. Compared with the traditional solution of setting lifting protrusions or convex surfaces on the support plate surface to lift the lifting component, this solution reduces the space required for the support plate and the lifting component to cooperate, making the structure of this water circuit motor more compact and occupying less installation space.

[0011] As a further preferred embodiment, the support plate is provided with a first clearance hole along the thickness direction.

[0013] As a further preferred embodiment, the top surface of the support plate is provided with a plurality of lifting grooves along the circumferential direction, and the lower end of the lifting member protrudes to form a plurality of lifting surfaces, the plurality of lifting surfaces being adapted to the plurality of lifting grooves one by one.

[0014] As a further preferred embodiment, the lifting component is provided with a plurality of fixing holes eccentrically, and the inner wall of the housing is provided with a plurality of positioning rods protruding axially, the positioning rods passing through the fixing holes.

[0015] As a further preferred embodiment, the lifting member includes a rod portion, the upper end of which passes through a shaft hole, and the lower end of which is fixed with a connecting portion, and the protrusion is fixedly disposed on the outer peripheral edge of the connecting portion.

[0016] As a further preferred embodiment, the sidewall of the rod protrudes outward from the wall thickness to form a reinforcing portion, which is connected to the connecting portion.

[0017] As a further preferred embodiment, the reinforcing part has several side facets that fit snugly against the inner wall of the housing.

[0018] As a further preferred embodiment, the fixing holes are evenly distributed along the circumference of the rod.

[0019] As a further preferred embodiment, the water circuit motor also includes a motor base plate with an electrical connection module, the motor base plate being disposed between the motor and the support plate, and the motor being fixed inside the housing via the motor base plate.

[0020] As a further preferred embodiment, the motor base plate is provided with a receiving groove for accommodating the support plate.

[0021] As a further preferred embodiment, the motor base plate is provided with a second clearance hole at the bottom wall of the receiving groove. When the lifting member is in the first position, the lower end of the protrusion passes through the support plate and extends into the second clearance hole. Overall, compared with the prior art, the above technical solution conceived in this application mainly possesses the following technical advantages:

[0022] 1. In the water circuit motor designed in this scheme, a lifting groove with a lifting surface is set on the support plate. The lifting adjustment of the lifting component can be realized by utilizing the thickness of the support plate itself, thereby reducing the space required when the support plate and the lifting component are matched, making the structure of this water circuit motor more compact.

[0023] 2. By providing a first clearance hole for the lifting component to extend into the support plate and a second clearance hole for the lifting component to extend into the motor base plate, the thickness of the support plate and the motor base plate can be fully utilized, effectively reducing the space required for the support plate and the lifting component to cooperate.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0036] This application discloses a compact water circuit motor. (Refer to...) Figures 1-4 The compact water-type motor includes a housing 1 with a shaft hole 1-1. Inside the housing 1, a motor 2, a support plate 3, and a lifting member 4 are sequentially arranged along the axial direction. The support plate 3 is connected to the rotor of the motor 2. A lifting groove 3-1 is provided on the top surface of the support plate 3, and the inner bottom surface of the lifting groove 3-1 is an axially spirally extending lifting surface 3-2. The lifting member 4 is connected to the housing 1 in a non-reverse connection and passes through the shaft hole 1-1. The side of the lifting member 4 facing the support plate 3 protrudes to form a protrusion 4-1 that matches the lifting groove 3-1. The lifting member 4 can move up and down between a first position and a second position of the housing 1 under the driving force of the motor 2 and gravity. When the protrusion 4-1 is in the first position (e.g., ...), ... Figure 2 As shown), the protrusion 4-1 is inserted into the lifting groove 3-1 and contacts the lifting surface 3-2; when the protrusion 4-1 is in the second position (as shown), Figure 3 As shown), the bottom surface of the protrusion 4-1 contacts the top surface of the support plate 3.

[0037] Under this design, by setting a lifting groove 3-1 with a lifting surface 3-2 on the support plate 3, the lifting member 4 can be adjusted by utilizing the thickness of the support plate 3. In actual use, the water circuit motor can be placed vertically, and the support plate 3 can be rotated by the motor 2, so that the lifting member 4 can be adjusted up and down under the spiral lifting force and gravity of the support plate 3, and the lifting member 4 can move up and down between the first position and the second position of the shell 1.

[0038] Compared to the traditional design that uses lifting protrusions and surfaces on the support plate 3 to lift the lifting component 4, the traditional design suffers from the problem of a large space required for the support plate 3 and lifting component 4 to mate, resulting in a larger size for the water circuit motor. This design reduces the space required for the support plate 3 and lifting component 4 to mate, making the water circuit motor more compact and requiring less installation space, thus facilitating user installation.

[0039] Furthermore, such as Figure 2 , Figure 3 As shown, in some embodiments, the housing 1 includes an upper housing portion 1-3 and a lower housing portion 1-4, which are detachably connected to each other. The upper housing portion 1-3 and the lower housing portion 1-4 form a mounting cavity for components such as the motor 2, the support plate 3, and the lifting member 4.

[0040] Furthermore, in some embodiments, reference is made to... Figure 2 , Figure 3 and Figure 5 The water-cooled motor also includes a motor base plate 6 with an electrical connection module 5. The motor base plate 6 is disposed between the motor 2 and the support plate 3, and is fixedly connected to the housing 1. The motor 2 is fixed inside the housing 1 through the motor base plate 6. The electrical connection module 5 is existing technology and is mainly used to realize the electrical connection and control between the motor 2 and an external power source. Typically, the electrical connection module 5 includes a first conductive terminal, a common terminal, and a second conductive terminal.

[0041] Furthermore, in some embodiments, such as Figures 4-5 As shown, to improve the installation stability of the support plate 3, the motor base plate 6 is provided with a receiving groove 6-1 for accommodating the support plate 3. Preferably, the support plate 3 is generally disc-shaped, and the receiving groove 6-1 is correspondingly set as a circular groove. The circumferential surface and bottom surface of the support plate 3 are in sliding contact with the inner wall of the receiving groove 6-1, and the top surface of the support plate 3 is in contact with the lifting member 4. The support plate 3 can rotate within the receiving groove 6-1 under the drive of the motor 2.

[0042] Furthermore, such as Figure 3 As shown, in some embodiments, a limiting rod 1-5 protrudes from the inner wall of the housing 1, and the end of the limiting rod 1-5 slides in contact with the top surface of the support plate 3 to axially limit the support plate 3, thereby further improving the installation stability of the support plate 3.

[0043] Furthermore, such as Figure 4As shown, in some embodiments, to improve the space utilization of the water circuit motor, the support plate 3 is provided with a first clearance hole 3-3 along the thickness direction, and the first clearance hole 3-3 is located at the lowest point of the lifting surface 3-2. When the lifting member 4 is in the first position, the lower end of the protrusion 4-1 extends into the first clearance hole 3-3.

[0044] Furthermore, such as Figure 5 As shown, in some embodiments, the motor base plate 6 is provided with a second clearance hole 6-2 at the bottom wall of the receiving groove 6-1. When the lifting member 4 is in the first position, the lower end of the protrusion 4-1 passes through the support plate 3 and extends into the second clearance hole 6-2.

[0045] Under this design, with limited dimensions, the first clearance hole 3-3 and the second clearance hole 6-2 allow the protrusion 4-1 in the lifting member 4 to extend in the direction of the motor 2, thereby extending the distance between the first position and the second position. This can improve the lifting adjustment range of the lifting member 4 to a certain extent, making full use of the thickness of the support plate 3 and the motor base plate 6, thereby reducing the space required for the support plate 3 to cooperate with the lifting member 4, which is conducive to the compact and miniaturized design of the water circuit motor.

[0046] Furthermore, such as Figure 7 , Figure 8 As shown, in some embodiments, the end of the support plate 3 facing the motor base plate 6 has an annular groove 3-4; correspondingly, the inner bottom wall of the receiving groove 6-1 has an annular protrusion 6-3 that matches the annular groove 3-4; after the support plate 3 is assembled in the receiving groove 6-1, the annular groove 3-4 and the annular protrusion 6-3 cooperate with each other to improve the assembly stability of the support plate 3 and the receiving groove 6-1.

[0047] Furthermore, such as Figure 4 As shown, in some embodiments, a rotor groove 3-5 is provided at the center of the support plate 3, and the rotor groove 3-5 extends radially along the support plate 3. Figure 7 As shown, a protrusion (usually formed by a pin) is fixedly provided on the outer periphery of the rotor of motor 2. The center of the end face of the motor base plate 6 has a through hole for the rotor to pass through, and the rotor can carry the protrusion and embed it into the rotor groove 3-5 along the through hole. In actual use of this water circuit motor, with the cooperation of the protrusion and the rotor groove 3-5, motor 2 can smoothly drive the support plate 3 to rotate.

[0048] Furthermore, such as Figure 4As shown, in some embodiments, the lifting groove 3-1 has two lifting surfaces 3-2, with opposite rotation directions. When the lifting member 4 is in the first position, the protrusion 4-1 simultaneously contacts the two lifting surfaces 3-2. This design not only increases the contact area between the support plate 3 and the lifting member 4, improving the support stability of the support plate 3 for the lifting member 4, but also allows the motor 2 to lift the lifting member 4 via the support plate 3 regardless of whether it rotates forward or backward.

[0049] Furthermore, in some embodiments, the top surface of the support plate 3 is provided with a plurality of lifting grooves 3-1 along the circumferential direction, and the lower end of the lifting member 4 protrudes to form a plurality of lifting surfaces 3-2, the plurality of lifting surfaces 3-2 being adapted to the plurality of lifting grooves 3-1 one by one. By providing a plurality of lifting grooves 3-1 and lifting surfaces 3-2, the support plate 3 can be evenly loaded, which can significantly improve the service life of the support plate 3 and ensure the long-term stable operation of this compact water circuit motor.

[0050] Furthermore, such as Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the lifting member 4 includes a rod portion 4-3, the upper end of which passes through a shaft hole 1-1, and a connecting portion 4-4 fixed to the lower end of the rod portion 4-3 (i.e., the end facing the support plate 3), while a protrusion 4-1 is fixedly disposed on the outer peripheral edge of the connecting portion 4-4. Preferably, the connecting portion 4-4 is disc-shaped and coaxial with the rod portion 4-3. The lifting member 4 is preferably an integral component.

[0051] Furthermore, in some embodiments, the connecting portion 4-4 of the lifting member 4 is provided with a plurality of fixing holes 4-2. Correspondingly, a plurality of positioning rods 1-2 are formed protruding axially on the inner wall of the housing 1, and the positioning rods 1-2 pass through the fixing holes 4-2 to realize the anti-reverse connection between the lifting member 4 and the housing 1.

[0052] Furthermore, in some embodiments, the fixing holes 4-2 are evenly distributed along the circumference of the rod portion 4-3; even further, the fixing holes 4-2 are evenly distributed within the connecting portion 4-4 at locations away from the side edge surface 4-6. Compared to other products, because the fixing holes 4-2 are further away from the side edge surface 4-6, the movement of the lifting member 4 is more stable when the motor 2 starts.

[0053] Furthermore, such as Figure 2 , Figure 3 and Figure 6 As shown, in some embodiments, the side wall of the rod portion 4-3 of the lifting member 4 protrudes outward from the wall thickness to form a reinforcing portion 4-5, which is connected to the connecting portion 4-4. In addition, the reinforcing portion 4-5 has a plurality of side facets 4-6, which fit snugly against the inner wall of the housing 1.

[0054] In this design, the reinforcing part 4-5 not only strengthens the lifting member 4 and enhances the connection stability between the connecting part 4-4 and the rod part 4-3, but its side face 4-6 also provides a backstop function for the lifting member 4. Additionally, in some other embodiments, the fixing hole 4-2 can also be provided in the reinforcing part 4-5.
