Description

Technical Field

[0001] This application relates to the field of automotive thermal management technology, specifically to a valve device. Background Technology

[0002] In valve devices of related technologies, the valve body and the interface are fixed by a connector. However, for the sake of connection convenience, there is a connection gap between the valve body and the connector, and between the interface and the connector, which causes the valve body and the interface to still shake after being fixed.

[0003] Therefore, how to provide a valve device that reduces the swaying of the interface relative to the valve body and improves the connection stability between the valve body and the interface has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this application is to provide a valve device that reduces the swaying of the interface relative to the valve body and improves the connection stability between the valve body and the interface.

[0005] To solve the above-mentioned technical problems, this application provides a valve device, comprising:

[0006] Valve body;

[0007] The interface section is defined as having an arrangement direction between the interface section and the valve body as the vertical direction, and a direction perpendicular to the vertical direction as the width direction. The interface section has a connecting groove and at least two second connecting cavities. Along the width direction, at least two second connecting cavities are respectively located on both sides of the connecting groove.

[0008] An interface connection part is fixedly connected to the valve body or is an integral structure therewith. The interface connection part has at least two first connection cavities, which are arranged along the width direction. The first connection cavities are located in the connection groove, and the second connection cavities correspond to the first connection cavities on the same side.

[0009] At least two connecting blocks, with the same portion of the connecting block located within the corresponding first connecting cavity and second connecting cavity;

[0010] At least one connector connects two connecting blocks arranged along the width direction, the upper end wall of the connecting block abuts against the upper inner wall forming the second connecting cavity to form a first abutting surface, and the lower end wall of the connecting block abuts against the lower inner wall forming the first connecting cavity to form a second abutting surface.

[0011] The second abutment surface extends along the width direction, and the extension direction of the first abutment surface forms an angle with the width direction. In the direction away from the connecting groove, the first abutment surface gradually slopes from bottom to top; or, the first abutment surface extends along the width direction, and the extension direction of the second abutment surface forms an angle with the width direction. In the direction from the center of the connecting groove toward the first connecting cavity, the second abutment surface gradually slopes from top to bottom.

[0012] The lower end wall of the interface connection part and the interface part abut to form a third abutment surface, and the third abutment surface extends along the width direction.

[0013] The valve device of this application connects the interface part and the interface connection part through a connecting block and a connecting piece. In the first abutting surface and the second abutting surface, one extends along the width direction, and the other extends at an angle to the width direction. The third abutting surface extends along the width direction. Under the combined action of the abutting limit between the connecting block and the interface connection part, the abutting limit between the connecting block and the interface part, and the abutting limit between the interface connection part and the interface part, the interface part is fixed in position relative to the interface connection part in both the vertical and width directions, thereby reducing the shaking between the valve body and the interface part and improving the connection stability between the valve body and the interface part.

[0040] This application provides valve devices according to some embodiments, including:

[0041] Valve body 1;

[0042] Interface 3, the arrangement direction of interface 3 and valve body 1 is defined as the vertical direction, the direction perpendicular to the vertical direction is defined as the width direction, interface 3 has a connecting groove 3a, interface 3 has at least two second connecting cavities 3b, along the width direction, at least two second connecting cavities 3b are respectively located on both sides of the connecting groove 3a;

[0043] Interface connection part 2, interface connection part 2 is fixedly connected to valve body 1 or is an integral structure, interface connection part 2 has at least two first connection cavities 2a, the at least two first connection cavities 2a are arranged along the width direction, the first connection cavity 2a is located in the connection groove 3a, and the second connection cavity 3b corresponds to the first connection cavity 2a on the same side.

[0044] At least two connecting blocks 4, with a portion of the same connecting block 4 located within the corresponding first connecting cavity 2a and second connecting cavity 3b;

[0045] At least one connector 5 connects two connecting blocks 4 arranged along the width direction. The upper end wall of the connecting block 4 abuts against the upper inner wall forming the second connecting cavity 3b to form a first abutting surface A. The lower end wall of the connecting block 4 abuts against the lower inner wall forming the first connecting cavity 2a to form a second abutting surface B.

[0046] The second abutment surface B extends along the width direction, and the extension direction of the first abutment surface A forms an angle with the width direction. In the direction away from the connecting groove 3a, the first abutment surface A gradually slopes upward from bottom to top; or, the first abutment surface A extends along the width direction, and the extension direction of the second abutment surface B forms an angle with the width direction. In the direction from the center of the connecting groove 3a toward the first connecting cavity 2a, the second abutment surface B gradually slopes downward from top to bottom.

[0047] The lower end wall of the interface connection part 2 and the interface part 3 abut against each other to form a third abutment surface C, and the third abutment surface C extends in the width direction.

[0048] In this article, Figure 4 Taking the perspective of [the location] as an example, the vertical direction is [in the vertical direction]. Figure 4 As shown, the first abutting surface A has an angle greater than zero between its extension direction and its width direction, and an angle greater than zero between its extension direction and its vertical direction.

[0049] In this embodiment of the valve device, the interface connection part 2 and the interface part 3 are fixed by at least two connecting blocks 4 and at least one connecting member 5. In the first embodiment, the interface connection part 2 is subjected to force distribution, such as... Figure 4 As shown, it can be seen that the middle part of the interface connection part 2 is subjected to an upward force F1, the left end of the interface connection part 2 is subjected to a downward force F2, and the right end of the interface connection part 2 is subjected to a downward force F3. Since the interface connection part 2 is in a fixed state and the interface connection part 2 is symmetrical from left to right, the interface connection part 2 is in force balance, that is, F1=F2+F3, F2=F3.

[0050] Simultaneously, force analysis of the two connecting blocks 4 reveals that the left connecting block 4 is subjected to a downward force F4, an upward force F5, and a rightward tension F6; the right connecting block 4 is subjected to a downward force F7, an upward force F8, and a leftward tension F9. Decomposing force F4 yields a downward component F41 and a leftward component F42; decomposing force F7 yields a downward component F71 and a rightward component F72. Since the structures of the two connecting blocks 4 are symmetrical, forces F4 and F7 are equal in magnitude. Forces F42 and F72 are equal in magnitude but opposite in direction. The tension F6 on the left connecting block 4 and the tension F9 on the right connecting block 4 are equal in magnitude but opposite in direction. Therefore, after the two connecting blocks 4 are connected by the connector 5, they are in a state of force equilibrium along the width direction. At the same time, since the component forces F41 and F71 are equal in magnitude, and the action forces F5 and F8 are equal in magnitude, the two connecting blocks 4 are in a state of force equilibrium along the vertical direction after being connected by the connector 5. F41 + F71 = F5 + F8. Since F5 = F2 and F8 = F3, F41 + F71 = F2 + F3 = F1.

[0051] Taking interface 3 as the research object, force analysis of interface 3 shows that the left end of interface 3 is subjected to an upward force F10, the right end of interface 3 is subjected to an upward force F11, and the closed end wall of the connecting groove 3a in interface 3 is subjected to a downward force F12. Decomposing the force F10 at the left end yields an upward component F101 and a rightward component F102. Decomposing the force F11 at the right end yields an upward component... Since the left and right ends of the interface part 3 are symmetrical, the component forces F111 and F112 are equal in magnitude and opposite in direction. Therefore, the interface part 3 is in a state of force equilibrium along the width direction. At the same time, since F101=F41, F111=F71, and F12=F1, the force state of the interface part 3 along the vertical direction is: F101+F111=F41+F71=F1=F10. It can be seen that the interface part 3 is in a state of force equilibrium along the vertical direction.

[0052] In the second embodiment, the interface connection portion 2 is subjected to a force component, such as... Figure 8As shown, it can be seen that the middle part of the interface connection part 2 is subjected to an upward force F1, the left end of the interface connection part 2 is subjected to a force F2 pointing to the lower right end, and the right end of the interface connection part 2 is subjected to a force F3 pointing to the lower left end. Decomposing the force F2, we can obtain a downward component F21 and a rightward component F22. Decomposing the force F3, we can obtain a downward component F31 and a leftward component F32. Since the interface connection part 2 is in a fixed state and the interface connection part 2 is symmetrical, the interface connection part 2 is in force balance, that is, F2=F3, F1=F21+F31, F22=F32.

[0053] Simultaneously, force analysis of the two connecting blocks 4 reveals that the left connecting block 4 is subjected to a downward force F4, an upward force F5, and a rightward tension F6; the right connecting block 4 is subjected to a downward force F7, an upward force F8, and a leftward tension F9. Decomposing force F5 yields an upward component F51 and a leftward component F42; decomposing force F8 yields an upward component F81 and a rightward component F82. Since the structures of the two connecting blocks 4 are symmetrical, forces F4 and F7 are equal in magnitude. Because F2 = F3 = F5 = F8, the component forces F... Forces F52 and F82 are equal in magnitude but opposite in direction. The tension force F6 on the left end connecting block 4 and the tension force F9 on the right end connecting block 4 are equal in magnitude but opposite in direction. Therefore, after the two connecting blocks 4 are connected by the connector 5, they are in a state of force equilibrium along the width direction. At the same time, since the component forces F51 and F81 are equal in magnitude, and the action force F4 and the action force F7 are equal in magnitude, the two connecting blocks 4 are in a state of force equilibrium along the up and down direction after being connected by the connector 5. F4 + F7 = F51 + F81. Since F5 = F2, F8 = F3, F51 = F21, and F81 = F31, therefore, F4 + F7 = F21 + F31 = F1.

[0054] Taking the interface part 3 as the research object, the force analysis of the interface part 3 shows that the left end of the interface part 3 is subjected to an upward force F11, the right end of the interface part 3 is subjected to an upward force F12, and the closed end wall of the connecting groove 3a in the interface part 3 is subjected to a downward force F10. Since F11=F4, F12=F7, and F10=F1, therefore, F11+F12=F4+F7=F1=F10. It can be seen that the interface part 3 is in a state of force equilibrium.

[0055] As can be seen from the above analysis, the valve device in this embodiment improves the connection method between the interface portion 3 and the interface connecting portion 2, so that the interface portion 3 is fixed relative to the interface connecting portion 2 in both the vertical and width directions. This keeps the interface portion 3 and the interface connecting portion 2 in a relatively fixed state, reducing the shaking between the valve body 1 and the interface portion 3 and improving the connection stability between the valve body 1 and the interface portion 3. In addition, only one connector 5 is used as a fastener, which simplifies the structure. The connecting block 4 slides with the wall forming the second connecting cavity 3b. During assembly, the connector 5 is pulled closer to the distance between the two connecting blocks 4 in the width direction, and the connecting block 4 slides relative to the second connecting cavity 3b, so that the interface portion 3 gradually rises until the lower end wall of the interface connecting portion 2 abuts against the bottom wall forming the connecting groove 3a.

[0056] Depend on Figure 2 As can be seen, in this embodiment, the two side walls of the interface connection part 2 arranged along the width direction are provided with two first connection cavities 2a, and the two first connection cavities 2a are distributed at intervals along the extension direction of the side wall of the interface connection part 2. The two side walls of the connection groove 3a arranged along the width direction are provided with two second connection cavities 3b, and the two second connection cavities 3b are distributed at intervals along the extension direction of the side wall of the connection groove 3a. The number of connection blocks 4 is four, and the number of connectors 5 is two.

[0057] Thus, both ends of the interface connection part 2 and the interface part 3 in the length direction are fixed by the connecting block 3 and the connector 5, so that the interface connection part 2 and the interface part 3 are balanced in the length direction, thereby improving the connection reliability of the interface connection part 2 and the interface part 3.

[0058] Furthermore, in this embodiment, there is a gap between the upper end wall of the connecting block 4 and the upper inner wall of the corresponding first connecting cavity 2a, and a gap between the lower end wall of the connecting block 4 and the lower inner wall of the corresponding second connecting cavity 3b.

[0059] As set up above, when the two connecting blocks 4 arranged along the width direction are connected by the connector 5, the connecting blocks 4 have movable gaps inside the corresponding first connecting cavity 2a and second connecting cavity 3b. This ensures that after the connection is completed, the upper end wall of the connecting block 4 and the upper inner wall forming the second connecting cavity 3b can reliably abut to form the first abutting surface A, the lower end wall of the connecting block 4 and the lower inner wall forming the first connecting cavity 2a can reliably abut to form the second abutting surface B, and the lower end wall of the interface connecting part 2 and the closed end wall of the connecting groove 3a can reliably abut to form the third abutting surface C, thus ensuring the connection stability between the valve body 1 and the interface part 3.

[0060] It is understood that since there is a gap between the lower end wall of the connecting block 4 and the lower end inner wall forming the corresponding second connecting cavity 3b, the structure of the lower end inner wall forming the second connecting cavity 3b is not limited. In this embodiment, the lower end inner wall forming the second connecting cavity 3b and the upper end inner wall forming the second connecting cavity 3b are parallel, so the second connecting cavity 3b can be milled in one step with a milling cutter, simplifying the processing steps and improving processing efficiency. The parallelism between the lower end inner wall forming the second connecting cavity 3b and the upper end inner wall forming the second connecting cavity 3b also facilitates the sliding of the connecting block.

[0061] Similarly, since there is a gap between the upper end wall of the connecting block 4 and the upper inner wall forming the first connecting cavity 2a, the structure of the upper inner wall forming the first connecting cavity 2a is not limited. For example, in Figure 4 In the illustrated embodiment, the upper inner wall of the first connecting cavity 2a and the lower inner wall of the first connecting cavity 2a are parallel, allowing the first connecting cavity 2a to be milled in one pass with a milling cutter, simplifying the machining process and improving machining efficiency. The parallelism between the upper and lower inner walls of the first connecting cavity 2a also facilitates the sliding of the connecting block.

[0062] Please refer to Figures 2-4 In the first embodiment of this application, the first connecting cavity 2a is a hole-like structure that penetrates the interface connecting portion 2 along the width direction, forming a lower inner wall of the first connecting cavity 2a that extends along the width direction. Therefore, in this embodiment, the second abutment surface B extends along the width direction from the middle of the connecting groove 3a to both sides of the connecting groove 3a; the first abutment surface A extends obliquely from bottom to top.

[0063] Please refer to Figures 5-6 In the second embodiment of this application, the first connecting cavity 2a is a groove-shaped structure recessed into the middle of the connecting groove 3a along the width direction. The first connecting cavity 2a is generally pointed, and the lower inner wall of the first connecting cavity 2a extends obliquely from top to bottom in the direction from the middle of the connecting groove 3a to both sides in the width direction of the connecting groove 3a. Therefore, in this embodiment, the second abutment surface B extends obliquely from top to bottom in the direction from the middle of the connecting groove 3a to both sides in the width direction of the connecting groove 3a, and the first abutment surface A extends along the width direction.

[0064] Please refer to Figure 2 , Figure 9 and Figure 10 , Figure 9 for Figure 1 A simplified structural diagram of one of the connecting blocks in the valve assembly; Figure 10 for Figure 1 A simplified structural diagram of another connecting block in the valve assembly.

[0065] In this embodiment, among the two connecting blocks 4 arranged along the width direction, the first one has a limiting hole 4a and the second one has a threaded connection hole 4b. The connecting member 5 includes a rod 51 that extends along the width direction. A part of the rod 51 is located in the limiting hole 4a. The connecting member 5 also includes a head 52. One end of the rod 51 is threadedly connected to the threaded connection hole 4b, and the other end of the rod 51 is fixedly connected to the head 52 or is an integral structure. Along the width direction, the head 52 of the connecting member 5 abuts against the first one to achieve limiting along the width direction.

[0066] As set above, in this embodiment, the connector 5 adopts the structure of a threaded connector. The two oppositely arranged connecting blocks 4 are connected as one piece by the threaded connector, which is reliable and easy to disassemble and assemble. In the process of connecting the two connecting blocks 4, the position of the two connecting blocks 4 can be slightly changed with the connection process of the connector 5. After the connection is completed, the upper end wall of the connecting block 4 and the upper inner wall of the second connecting cavity 3b can reliably abut to form the first abutting surface A, the lower end wall of the connecting block 4 and the lower inner wall of the first connecting cavity 2a can reliably abut to form the second abutting surface B, and the lower end wall of the interface connecting part 2 and the closed end wall of the connecting groove 3a can reliably abut to form the third abutting surface C, thus ensuring the connection stability between the valve body 1 and the interface part 3.

[0067] Please continue to refer to this. Figure 4 and Figure 9 In this embodiment, the limiting hole 4a includes a constant diameter section 4a1 and a variable diameter section 4a2. The constant diameter section 4a1 is closer to the threaded connection hole 4b than the variable diameter section 4a2. The diameter of the variable diameter section 4a2 gradually expands in the direction away from the constant diameter section 4a1. The diameter of the head 52 gradually expands in the direction away from the rod 51. The outer peripheral wall of the head 52 and the inner peripheral wall forming the variable diameter section 4a2 fit together to achieve limiting in the width direction.

[0068] As configured above, in this embodiment, the variable diameter section 4a2 is used to at least partially accommodate the head 52 of the connector 5, preventing the head 52 of the connector 5 from being exposed, ensuring the external neatness of the valve device after connection, and improving the quality of the valve device; while the outer contour of the head 52 matches the inner contour of the variable diameter section 4a2, and the outer peripheral wall of the head 52 and the inner peripheral wall of the variable diameter section 4a2 fit together to achieve axial limiting, ensuring reliable connection between the connector 5 and the corresponding connecting block 4.

[0069] Please refer to Figure 11 , Figure 11 for Figure 1 A schematic diagram of the connecting block in the valve device.

[0070] In this embodiment, the connecting block 4 includes a first connecting block 41 and a second connecting block 42. Along the width direction, the second connecting block 42 is located near the middle of the connecting groove 3a relative to the first connecting block 41. The first connecting block 41 is at least partially located inside the second connecting cavity 3b. The upper end wall of the first connecting block 41 and the upper end inner wall forming the second connecting cavity 3b abut against each other to form a first abutting surface A.

[0071] The second connecting block 42 is located at least partially inside the first connecting cavity 2a, and the lower end wall of the second connecting block 42 abuts against the lower end inner wall forming the first connecting cavity 2a to form a second abutting surface B.

[0072] As configured above, the first connecting block 41 is used to cooperate with the second connecting cavity 3b to realize the assembly connection of the connecting block 4 and the interface part 3. The second connecting block 42 is used to cooperate with the first connecting cavity 2a to realize the assembly connection of the connecting block 4 and the interface connection part 2. Thus, the connecting block 4 can connect the interface part 3 and the interface connection part 2 into one unit to complete the assembly of the valve device.

[0073] Depend on Figure 11 As can be seen, in this embodiment, the first connecting block 41 and the second connecting block 42 are an integral structure. The two are described separately here only to better describe their structure and function. Of course, in practice, it is also feasible for the first connecting block 41 and the second connecting block 42 to be separate structures and then fixed together.

[0074] Please refer to Figures 11-13 , Figure 12 for Figure 1 A partial structural diagram of the valve body and interface connection in a valve device; Figure 13 for Figure 1 A schematic diagram of the interface section in the valve device.

[0075] In this embodiment, the limiting hole 4a or the threaded connection hole 4b penetrates the upper end wall of the corresponding second connecting block 42 to form a notch a, and the upper end inner wall of the first connecting cavity 2a and the upper end inner wall of the second connecting cavity 3b are provided with clearance grooves b at least at the positions corresponding to the notch a.

[0076] The notch a and the clearance groove b are used to avoid the connector 5. It is precisely because of the notch a and the clearance groove b that the size of the connector 5 can be increased, the structural strength of the connector 5 can be improved, the connection between the interface 3 and the interface connection 2 can be made reliable, and the structural stability of the valve device can be improved.

[0077] It is understandable that when the size of connector 5 is small, it is also feasible not to provide the above-mentioned notch a and clearance groove b.

[0078] In this embodiment, the interface connection part 2 and the valve body 1 are welded and fixed, and the connection is reliable.

[0079] Depend on Figure 12 As can be seen, the interface connection part 2 has a valve body connection part 21, and the valve body connection part 21 has a storage tank 21a, in which the molten solder is located. In this way, the storage tank 21a can collect a portion of the solder and reduce solder overflow.

[0080] Depend on Figure 13 As can be seen, in this embodiment, one of the side walls of the connecting groove 3a is provided with a clearance notch 3c, which is used to avoid the air pressure guide pipe of the valve body 1.

[0081] Please refer to Figure 14 , Figure 14 for Figure 13 A partial sectional view of the interface section along its width.

[0082] In this embodiment, the closed end wall of the connecting groove 3a has process grooves 3d at both ends in the width direction, and the process grooves 3d are connected to the second connecting cavity 3b at the corresponding ends.

[0083] With the above settings, when the milling cutter completes the machining of the second connecting cavity 3b, the process groove 3d provides the milling cutter with retraction space, which facilitates the retraction operation and improves the feasibility of the process.

[0084] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
