DETAILED DESCRIPTION

[0023] In order to make the purpose, scheme and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the utility model. Unless otherwise specified, the terms used in this article have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0024] For a clearer description, unless otherwise specified, the meanings of the directional terms appearing in this article are as follows: the first direction refers to the direction from the actuator to the valve body, and the second direction refers to the direction perpendicular to the first direction. The actuator is assembled integrally with the valve body along the first direction.

[0025] Figure 1 A schematic diagram of an electric valve 100 according to an embodiment of the present invention is shown. The electric valve 100 mainly includes an actuator and a valve body facing the actuator along a first direction A. The actuator has a first body portion 110, and the valve body has a second body portion 120. The actuator controls the movement of the valve body by connecting to an output shaft (not shown) of the valve body, thereby controlling the operating state of the electric valve 100. The actuator of the present invention may be a motor, but the present invention is not intended to limit the type of the actuator, and the actuator may also be any other suitable device having a driving function.

[0026] In the prior art, in order to fix the actuator to the valve body, a mounting bracket fixedly connected to the actuator and the valve body is specially provided, and a screw passes through the mounting hole of the mounting bracket along the first direction A to fix the actuator to the valve body. Because the mounting bracket needs to have a mounting hole in the first direction, the presence of the mounting bracket inevitably leads to an increase in the overall size of the electric valve 100 (especially the size in the second direction), which is not conducive to the use of the electric valve 100. Specifically, in one embodiment, the first direction A can be the direction of the rotation axis of the valve core of the electric valve. In another embodiment, the first direction A can be the direction of the rotation axis of the rotor and / or output shaft of the actuator.

[0027] In order to improve the defects of the prior art, in the embodiments of the present utility model, Figure 2 , 3As shown, the first main body 110 of the actuator and the second main body 120 of the valve body are respectively provided with a first connecting member 130 and a second connecting member 140, and the first connecting member 130 and the second connecting member 140 are matched and connected to fix the actuator to the valve body. More importantly, the first connecting member 130 and the second connecting member 140 at least partially overlap in the first direction A. Since the first connecting member 130 and the second connecting member 140 at least partially overlap in the first direction A, the first connecting member 130 can be fixedly connected with the second connecting member 140 by matching in the second direction, rather than being fixedly connected by matching in the first direction A as in the prior art, thereby avoiding unnecessary increase in the size of the electric valve 100 in the second direction caused by the connecting members 130 and 140.

[0028] Optionally, the first connecting member 130 and the second connecting member 140 may be provided with a first connecting portion 134 and a second connecting portion 144, respectively, the first connecting portion 134 and the second connecting portion 144 at least partially overlap in the first direction A, the first connecting portion 134 and the second connecting portion 144 are provided with a first connecting hole 136 and a second connecting hole 146, respectively, and the line between the first connecting hole 136 and the second connecting hole 146 is perpendicular to the first direction A. The first connecting member 130 and the second connecting member 140 are connected by the matching connection of the first connecting portion 134 and the second connecting portion 144, so that the actuator is fixedly connected to the valve body. The first connecting hole 136 and the second connecting hole 146 can be used for connection with the screw 160, that is, the screw 160 passes through the first connecting hole 136 and the second connecting hole 146 to fix the first connecting portion 134 and the second connecting portion 144. Alternatively, the first connecting member 130 may also be provided with a buckle, which is inserted into the second connecting hole 146 to fix the first connecting portion 134 to the second connecting portion 144. It should be understood that the present invention is not intended to limit the specific connection form between the first connecting portion 134 and the second connecting portion 144, and any other suitable connection method may be used to fix the first connecting portion 134 to the second connecting portion 144.

[0029] Preferably, the first connecting member 130 may have a first main body 132 that is cylindrical and extends along the first direction A, the first main body 132 is provided with an opening 138 at one end facing the second connecting member 140, the first connecting portion 134 is provided on the side wall of the first main body 132, and the first connecting member 130 is arranged radially outside the second connecting member 140. In this way, the first connecting member 130 can be installed to the second connecting member 140 by sleeve-arranging the first connecting member 130 on the outside of the second connecting member 140, and then the first connecting member 130 and the second connecting member 140 are fixedly connected by other means, and such an installation method is easy to operate.

[0030] Preferably, the second connector 140 may have a second body 142 at the center of the second connector 140, and the second connection portion 144 protrudes radially outward from the second body 142. The first body 132 and the second body 142 may have a cylindrical shape, and the axis of the first body 132 is aligned with the axis of the second body 142. In this way, the operation of mounting the first connector 130 to the second connector 140 is simpler by aligning the axis of the first body 132 with the axis of the second body 142.

[0031] Optionally, the first connecting member 130 may be provided with three first connecting portions 134, and the second connecting member 140 may be provided with three second connecting portions 144 corresponding to the first connecting portions 134, and the three first connecting portions 134 are arranged at intervals around the first body 132. In this way, the first connecting portion 134 can be fixed to the second connecting portion 144 by three screws 160 passing through three corresponding first connecting holes and second connecting holes, and increasing the number of fixing components helps to improve the stability of the fixed connection between the actuator and the valve body. It should be understood that the utility model is not intended to limit the number of the first connecting portion 134 and the second connecting portion 144, and two, four, or any other suitable number of the first connecting portion 134 and the second connecting portion 144 may also be used.

[0032] Preferably, a reinforcing rib 150 may be provided between the first connecting member 130 and the first main body portion 110 of the actuator, and the reinforcing rib 150 can enhance the connection strength between the first connecting member 130 and the first main body portion 110 of the actuator.

[0033] exist Figure 3 In the disclosed embodiment, the second connection parts 144 are evenly distributed on the outer peripheral wall of the second body. The number of second connection parts can be 2, 3, 4, 5, 6, etc. Through such an arrangement, the radial orientation of the actuator can be adjusted as needed. The number of first connection parts can be 2, 3, 4, 5, 6, etc., and does not have to be consistent with the number of second connection parts. When installed on the thermal management integrated module, it can be adjusted as needed, with high installation flexibility. It can be understood that the more the number of connection parts, the more adjustable options. Of course, in order to achieve the above-mentioned adjustment function, the second connection parts 144 can also be unevenly arranged, in which case the number of first connection parts only needs to be one, that is, one screw is installed.

[0034] In addition, the electric valve 100 of the present invention may be used in systems employing the electric valve 100 , such as thermal management systems.

[0035] This document describes in detail several exemplary embodiments of the present invention with reference to preferred embodiments. However, it will be understood by those skilled in the art that, without departing from the concept of the present invention, various modifications and variations may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present invention may be combined without exceeding the protection scope of the present invention, which is determined by the appended claims.
