[0046] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0047] Reference below Figures 1-10 A control valve 100 according to an embodiment of the present invention is described.

[0048] like Figures 1-10 As shown, the control valve 100 according to an embodiment of the present invention includes: a valve body 10 and a valve core 20, the valve body 10 can have a liquid inlet 111 and a liquid outlet 112, the valve core 20 can be arranged in the valve body 10, and the valve core 20 can be movable relative to the valve body 10, for controlling the on and off of the liquid inlet 111 and the liquid outlet 112.

[0049] It can be understood that the valve core 20 can disconnect the liquid inlet 111 and the liquid outlet 112 when the liquid flows in the opposite direction (from the liquid outlet 112 to the liquid inlet 111) to prevent the liquid from flowing through the control valve 100, and the valve core 20 can move when the liquid flows in the forward direction and the liquid pressure reaches a certain value to connect the liquid inlet 111 and the liquid outlet 112, thereby ensuring that the liquid first flows into the control valve 100 from the liquid inlet 111 and then flows out of the control valve 100 from the liquid outlet 112 to control the unidirectional flow of the liquid.

[0050] In which, the valve body 10 may include a valve seat 11 and a valve body 12, the valve body 12 may be defined by a slot 1211, the valve body 12 may be provided with a positioning portion, the valve seat 11 may have a fixing portion 114 and an elastic arm 115, the elastic arm 115 may be connected to the fixing portion 114, at least a portion of the valve seat 11 (for example, the fixing portion 114 and the elastic arm 115) may extend into the valve body 12, and the valve seat 11 may be rotated relative to the valve body 12 so that the fixing portion 114 is inserted into the slot 1211, thereby realizing mutual limitation between the valve seat 11 and the valve body 12.

[0051] At the same time, the elastic arm 115 can be elastically matched with the positioning portion when the fixing portion 114 is inserted into the slot 1211, that is, the elastic arm 115 can be elastically deformed. On the one hand, the fixing portion 114 and the slot 1211 can be pressed against each other to prevent the valve seat 11 and the valve body 12 from being axially moved (e.g., Figure 2 On the other hand, the valve seat 11 and the valve body 12 can be limited in the circumferential direction of the valve body 10 to prevent the valve seat 11 and the valve body 12 from rotating relative to each other after assembly, thereby improving the limiting effect between the valve seat 11 and the valve body 12 and reducing the probability of the valve seat 11 and the valve body 12 being separated when the control valve 100 vibrates during operation, thereby improving the reliability and stability of the control valve 100.

[0052] According to the control valve 100 of the embodiment of the present invention, a rotatable and detachable valve seat 11 and valve body 12 are provided, and a movable valve core 20 is provided between the valve seat 11 and the valve body 12, so that the valve core 20 can move under the action of liquid flow direction and pressure to control the opening and closing of the liquid inlet 111 and the liquid outlet 112, thereby controlling the unidirectional flow of the liquid. At the same time, the number of parts of the control valve 100 can be reduced, the structure of the control valve 100 can be simplified, the cost can be reduced, and the assembly of the control valve 100 is convenient.

[0053] By arranging an elastic arm 115 on the fixing portion 114 of the valve seat 11, and the elastic arm 115 can cooperate with the positioning portion when the fixing portion 114 is inserted into the slot 1211, the limiting effect between the valve seat 11 and the valve body 12 can be improved, so that the assembly of the control valve 100 is tighter, thereby reducing the probability of the valve seat 11 and the valve body 12 being separated when the control valve 100 generates vibration during operation, thereby improving the reliability and stability of the control valve 100.

[0054] like Figure 5 、 Figure 6 and Figure 7 As shown, according to some embodiments of the present invention, the positioning portion can be a positioning groove 1212, and a positioning protrusion 1151 can be provided on the elastic arm 115. When the fixing portion 114 of the valve seat 11 is inserted into the slot 1211 of the valve body 12, the positioning protrusion 1151 of the elastic arm 115 can be plugged into and matched with the positioning groove 1212, so as to realize the circumferential limitation of the valve seat 11 and the valve body 12 on the valve body 10, and prevent the valve seat 11 and the valve body 12 from rotating relative to each other after assembly.

[0055] Moreover, the elastic arm 115 can undergo elastic deformation, thereby increasing the force between the positioning protrusion 1151 and the positioning groove 1212, preventing the positioning protrusion 1151 from being separated from the positioning groove 1212, and improving the limiting effect between the valve seat 11 and the valve body 12; alternatively, the positioning portion can be the positioning protrusion 1151, and the positioning groove 1212 can be provided on the elastic arm 115, and the positioning protrusion 1151 can be plugged into and fitted with the positioning groove 1212 of the elastic arm 115.

[0056] like Figure 6 and Figure 7 As shown, in some examples, the protruding size of the positioning protrusion 1151 can be greater than the depth of the positioning groove 1212, that is, a portion of the positioning protrusion 1151 can be located outside the positioning groove 1212 to tilt the elastic arm 115, which can ensure that the elastic arm 115 undergoes elastic deformation, which is beneficial to increase the force between the positioning protrusion 1151 and the positioning groove 1212, and can prevent the positioning protrusion 1151 from being separated from the positioning groove 1212, thereby improving the limiting effect between the valve seat 11 and the valve body 12, and can prevent the valve seat 11 and the valve body 12 from loosening.

[0057] like Figure 2 、 Figure 5 and Figure 7 As shown, in some examples, the valve seat 11 can be moved in a first direction (eg Figure 2The elastic arm 115 can extend along a circumferential direction perpendicular to the first direction, that is, the elastic arm 115 can extend along the circumference of the valve body 10, and the positioning protrusion 1151 can protrude from the elastic arm 115 along the first direction, that is, the positioning groove 1212 can be located on the bottom wall of the slot 1211, so that the positioning protrusion 1151 and the positioning groove 1212 can be plugged into each other.

[0058] Or, as Figure 8 、 Figure 9 and Figure 10 As shown, the positioning protrusion 1151 can be arranged in a direction perpendicular to the first direction (eg Figure 2 The protruding elastic arm 115 (from the inside to the outside as shown), that is, the positioning groove 1212 can be located on the side wall of the slot 1211, so that the positioning protrusion 1151 is plugged into and matched with the positioning groove 1212.

[0059] like Figure 5 、 Figure 6 and Figure 7 As shown, in some examples, the positioning protrusion 1151 can be cylindrical, that is, the positioning groove 1212 can be a cylindrical hole, which can improve the limiting effect between the positioning protrusion 1151 and the positioning groove 1212, making the assembly of the control valve 100 tighter, and preventing the valve seat 11 and the valve body 12 from rotating with each other after assembly, thereby improving the reliability and stability of the control valve 100.

[0060] Alternatively, the positioning protrusion 1151 can be hemispherical, that is, the wall surface inside the positioning groove 1212 is an arc surface. On the basis of ensuring the limiting effect between the positioning protrusion 1151 and the positioning groove 1212, the smoothness of the insertion or disengagement of the positioning protrusion 1151 and the positioning groove 1212 can be improved, which is convenient for disassembly and assembly.

[0061] like Figure 2 and Figure 6 As shown, according to some embodiments of the present invention, the valve seat 11 can be moved in a first direction (e.g., Figure 2 The fixing portion 114 extends into the valve body 12 in a first direction (as shown in the figure from top to bottom). Figure 2 The dimension of the slot 1211 in the first direction (as shown in the up and down direction) is h1. Figure 2 The dimension in the up and down directions shown in the figure is h2. If the value of h2-h1 is too large, the gap between the fixing portion 114 and the slot 1211 will be large, which will affect the limiting effect between the valve seat 11 and the valve body 12. If the value of h2-h1 is too small, the fixing portion 114 will be difficult to insert into the slot 1211.

[0062] Therefore, the value of h2-h1 can be limited to between 0.05mm-0.25mm, and h2-h1 can be any point value of 0.05mm, 0.10mm, 0.15mm, 0.20mm, 0.25mm or a range value between any two of them. This can ensure that the fixing part 114 is normally inserted into the slot 1211 to achieve normal assembly of the valve seat 11 and the valve body 12, and can improve the limiting effect between the valve seat 11 and the valve body 12, prevent the valve seat 11 and the valve body 12 from loosening, and improve the reliability and stability of the control valve 100.

[0063] It can be understood that since the protruding size of the positioning protrusion 1151 can be larger than the depth of the positioning groove 1212, the positioning protrusion 1151 can push up the elastic arm 115 after the fixing part 114 is inserted into the slot 1211. On the one hand, it can ensure that the elastic arm 115 undergoes elastic deformation. On the other hand, it is beneficial for the elastic arm 115 and the wall of the slot 1211 to be squeezed against each other, thereby helping to improve the limiting effect between the valve seat 11 and the valve body 12.

[0064] like Figure 5 and Figure 7 As shown, according to some embodiments of the present invention, the valve body 12 may be defined with a mounting groove 121 and a stopper 122, one end of the mounting groove 121 (such as Figure 7 The upper end (as shown) is open, the stop portion 122 protrudes from the side wall surface of the installation groove 121, and a slot 1211 can be defined between the stop portion 122 and the bottom wall of the installation groove 121.

[0065] At least a portion of the valve seat 11 (for example, the fixing portion 114 and the elastic arm 115) can extend into the valve body 12 through the open end of the mounting groove 121, and the valve seat 11 can rotate relative to the valve body 12 so that the fixing portion 114 is inserted into the slot 1211, so that the fixing portion 114 can contact the stopper 122 and the bottom wall of the slot 1211 respectively, so that the valve seat 11 and the valve body 12 can be aligned in the axial direction of the valve body 10 (such as Figure 2 The upper and lower directions shown are limited.

[0066] like Figure 8 、 Figure 9 and Figure 10 As shown, the positioning portion can be located on the bottom wall of the mounting groove 121 or the side wall of the mounting groove 121. Taking the positioning portion as the positioning groove 1212 as an example, a positioning protrusion 1151 can be provided on the elastic arm 115, and the positioning groove 1212 can be located on the bottom wall of the mounting groove 121.

[0067] The positioning protrusion 1151 can be arranged along a first direction (eg Figure 5The elastic arm 115 is protruded from the top to the bottom direction as shown in the figure, so that the positioning protrusion 1151 is plugged into the positioning groove 1212; alternatively, the positioning groove 1212 can be located on the side wall of the mounting groove 121, and the positioning protrusion 1151 can be along a direction perpendicular to the first direction (as shown in the figure). Figure 9 The elastic arm 115 protrudes from the inside to the outside (as shown) to facilitate the insertion and cooperation between the positioning protrusion 1151 and the positioning groove 1212.

[0068] like Figure 1 、 Figure 2 and Figure 6 As shown, according to some embodiments of the present invention, the valve seat 11 may have a valve seat channel 113, the valve seat channel 113 may connect the liquid inlet 111 and the liquid outlet 112, the valve core 20 may be arranged in the valve seat channel 113, the valve core 20 may move in the valve seat channel 113, and an elastic member 30 may be provided between the valve core 20 and the valve body 12, the elastic member 30 may be elastically deformed during the movement of the valve core 20, so that the valve core 20 can move when the pressure in the valve seat channel 113 is greater than a predetermined value, and it is beneficial to reset the valve core 20 to prevent the liquid from flowing back through the control valve 100, which is beneficial to controlling the unidirectional flow of the liquid.

[0069] Among them, when the pressure in the valve seat channel 113 is greater than a predetermined value, that is, when the liquid flows in the forward direction (from the liquid inlet 111 to the liquid outlet 112) and the liquid pressure reaches a certain value, the valve core 20 can move to connect the valve seat channel 113 with the liquid inlet 111 and the liquid outlet 112, and at the same time the elastic member 30 undergoes elastic deformation, thereby ensuring that the liquid first flows into the valve seat channel 113 from the liquid inlet 111, and then flows out of the valve seat channel 113 from the liquid outlet 112.

[0070] When the pressure at the valve seat channel 113 is less than a predetermined value or the liquid flows in the reverse direction, the elastic member 30 can drive the valve core 20 to reset, and the valve core 20 can disconnect the liquid inlet 111 and the liquid outlet 112 during the resetting process, thereby preventing the liquid from flowing in the reverse direction (from the liquid outlet 112 to the liquid inlet 111) through the control valve 100, thereby controlling the unidirectional flow of the liquid.

[0071] like Figure 2 、 Figure 4 and Figure 6 As shown, in some examples, the inner wall surface of the valve seat 11 may have a sealing section 116, and the sealing section 116 may be located between the liquid inlet 111 and the liquid outlet 112. A valve core sealing ring 24 may be provided on the valve core 20, and the valve core sealing ring 24 may abut against the sealing section 116 to disconnect the connection between the liquid inlet 111 and the liquid outlet 112, and to achieve sealing of the valve seat channel 113.

[0072] Therefore, when the liquid inlet 111 and the liquid outlet 112 are disconnected, the probability of liquid flowing through the control valve 100 due to excessive liquid pressure can be reduced, and the reliability and stability of the control valve 100 can be improved; when the pressure in the valve seat channel 113 is greater than a predetermined value, the valve core 20 can move in the valve seat channel 113, that is, the valve core sealing ring 24 and the sealing section 116 can be arranged at intervals to connect the liquid inlet 111 and the liquid outlet 112.

[0073] like Figure 2 、 Figure 3 and Figure 4 As shown, in some examples, the outer periphery of the valve core 20 may be provided with a stop groove 21, and the stop groove 21 may be inward (eg Figure 4 As shown in the figure, the valve core sealing ring 24 is recessed (from the outside to the inside), and the valve core sealing ring 24 can be set in the stop groove 21, which can limit the valve core sealing ring 24 and prevent the valve core sealing ring 24 from detaching, which is beneficial to improving the sealing effect of the valve seat channel 113.

[0074] like Figure 3 and Figure 4 As shown, in some examples, the valve core 20 may have a positioning groove, and the valve seat 11 may have a positioning rib 117. The positioning groove or the positioning rib 117 may be respectively along the movable direction of the valve core 20 (such as Figure 4 The positioning rib 117 extends in the upper and lower directions as shown, and the positioning rib 117 can be plugged into the positioning groove to achieve the positioning of the valve core 20 activity, which is beneficial to reduce the influence of the processing and assembly errors on the valve core 20 activity and improve the stability of the valve core 20 activity.

[0075] Alternatively, the valve core 20 may have a positioning rib 117, the valve seat 11 may have a positioning groove, and the positioning rib 117 may be plugged into the positioning groove; it can be understood that the number of positioning ribs 117 can be four, and the four positioning ribs 117 can be arranged at intervals along the circumference of the valve seat 11, which can improve the positioning effect of the valve core 20 and prevent the valve core 20 and the valve seat 11 from rotating relative to each other, thereby improving the stability of the valve core 20 movement.

[0076] like Figure 3 and Figure 4 As shown, in some examples, the outer periphery of the valve core 20 may be provided with a sliding portion 22, which may be outward (eg Figure 4 Compared with the contact between the entire side wall of the valve core 20 and the inner wall of the valve seat channel 113, the contact area between the valve core 20 and the inner wall of the valve seat channel 113 can be reduced, and the sliding portion 22 can extend along the circumference of the valve core 20 and form a ring, so that the valve core 20 can be radially (such as Figure 2The force in the inner and outer directions (as shown) is more uniform, which can improve the support effect on the valve core 20, thereby improving the smoothness of the sliding of the valve core 20 and facilitating operation.

[0077] It can be understood that the positioning groove or positioning rib 117 of the valve core 20 can be set on the sliding part 22. On the basis of ensuring the plug-in fit of the positioning groove and the positioning rib 117, the sliding part 22 can be prevented from interfering with the valve seat 11, thereby realizing the positioning of the valve core 20 movement, improving the stability of the valve core 20 movement, and at the same time improving the smoothness of the sliding of the valve core 20.

[0078] like Figure 3 and Figure 4 As shown, in some examples, the sliding portion 22 may include at least two, multiple sliding portions 22 may be arranged along the moving direction of the valve core 20 (eg Figure 4 The sliding portions 22 are arranged at intervals (in the upper and lower directions shown), and the sizes of the multiple sliding portions 22 can be the same, which can improve the support effect on the valve core 20, prevent the valve core 20 from loosening when sliding, and improve the reliability and stability of the control valve 100.

[0079] At the same time, the sealing performance of the control valve 100 can be improved to prevent the control valve 100 from leaking liquid when the liquid inlet 111 is disconnected from the liquid outlet 112. The number of sliding parts 22 can be two, which is convenient for processing on the basis of ensuring the normal movement of the valve core 20. It can be understood that the two adjacent sliding parts 22 are spaced apart from each other, which can reduce the weight of the valve core 20 on the basis of ensuring the sealing performance of the control valve 100, thereby improving the sensitivity of the use of the control valve 100 and reducing costs.

[0080] like Figure 2 and Figure 3 As shown, in some examples, the end of the valve core 20 facing the valve body 12 (such as Figure 3 The lower end shown in FIG. 2 may be provided with a limiting boss 23, and the elastic member 30 may be a spring, one end of which (as shown in FIG. Figure 2 The upper end shown in FIG20 can be sleeved on the limiting boss 23 to achieve the positioning of the spring and facilitate the assembly of the spring, thereby preventing the spring from moving in the radial direction of the valve body 10 (such as Figure 2 The movement or deformation of the valve core 20 can be improved, and the stability of the overall structure of the control valve 100 can be improved.

[0081] like Figure 2 and Figure 7 As shown, in some examples, the valve body 12 may further define a limiting groove 123, and the limiting groove 123 may be away from the valve core 20 (eg, Figure 2 The other end of the elastic member 30 (as shown in the direction from top to bottom) is recessed. Figure 2The lower end shown in the figure can be extended into the limiting groove 123, so that the elastic member 30 can be installed and positioned, and a certain deformation space can be provided for the elastic deformation of the elastic member 30, thereby ensuring that the elastic member 30 is elastically deformed when the valve core 20 moves, and ensuring the normal use of the control valve 100.

[0082] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the valve body 12 can be arranged at one end of the valve seat 11 (such as Figure 2 The lower end shown in FIG), the end of the valve seat 11 away from the valve body 12 (as shown in FIG Figure 2 The upper end shown in FIG. 1 may have a liquid inlet 111, and the side wall of the valve seat 11 may also have a liquid outlet 112, so that the liquid can be discharged from one end of the valve body 12 (such as Figure 2 The upper end shown in FIG. 11 is connected to the liquid inlet 111 and then flows along the radial direction of the valve body 12 (as shown in FIG. Figure 2 The liquid flows out through the liquid outlet 112 (from the inside to the outside as shown), thereby controlling the unidirectional flow of the liquid.

[0083] According to the thermal management system of the embodiment of the present invention, the control valve 100 is included. By adopting the above-mentioned control valve 100, the number of components of the thermal management system can be reduced, the cost can be reduced, and the assembly of the control valve 100 is more secure, which can improve the reliability and stability of the thermal management system.

[0084] The vehicle according to the embodiment of the present invention includes a thermal management system. By adopting the above-mentioned thermal management system, the number of vehicle parts can be reduced, the cost can be reduced, and the assembly of the control valve 100 can be tightened, which can improve the reliability and stability of vehicle use.
