[0030] The technical solution of the specific implementation mode is described below with reference to the accompanying drawings.

[0031] like Figure 1-16 As shown,

[0032] An electric control component includes a circuit board 200, at least one electric connection unit 1 and at least one driving mechanism 300, wherein the electric connection unit 1 is at least partially located between the circuit board 200 and the driving mechanism 300, the electric connection unit 1 is connected to the circuit board 200 (in this embodiment, the electric connection unit 1 is fixedly connected and electrically connected to the circuit board 200), the circuit board 200 has a first face 203 facing the driving mechanism 300, the driving mechanism 300 has at least one receiving wall 3021, the electric connection unit 1 includes at least one abutting wall 112, the receiving wall 3021 abuts against the abutting wall 112 to realize the electric connection unit 1 Electrically connected to the driving mechanism 300; the electrical connection unit 1 can be deformed; the electrical connection unit 1 has a connecting portion 11 and at least one elastic main portion 12, the elastic main portion 12 can be deformed, the elastic main portion 12 and the connecting portion 11 are both located between the receiving wall 3021 and the abutting wall 112, in the vertical direction, the connecting portion 11 is closer to the receiving wall 3021 than the elastic main portion 12, and the sum of the length of the elastic main portion 12 (the length is that of the path length from one end of the elastic main portion 12 along its extension direction to the other end) and the thickness of the connecting portion 11 is greater than the distance value n between the receiving wall 3021 and the first surface portion 203.

[0033] Therefore, when the electrical connection unit 1 is used to connect with the driving mechanism 300, if there is a deviation in the height of the driving mechanism 300, since the elastic main body 12 can be deformed, the electrical connection unit 1 has an elastic main body 12, and the length of the elastic main body 12 is greater than the distance value between the receiving wall 3021 and the first surface 203. During assembly, the elastic main body 12 of the electrical connection unit 1 can be deformed so that it can adapt to driving mechanisms 300 of different heights. The deformation amount of driving mechanisms 300 of different heights when connected will be different, thereby ensuring that the electrical connection unit 1 is connected to the driving mechanism 300 in place, and further ensuring the connection between the circuit board 200 and the driving mechanism 300.

[0034] In this embodiment, the electrical connection unit 1 includes a connection portion 11 and two elastic main body portions 12. The elastic main body portion 12 has a first end 121 and a second end 122. The electrical connection unit 1 has at least one fixing portion 13. The number of fixing portions 13 is the same as the number of elastic main body portions 12. The fixing portion 13 is connected to the circuit board 200. The two ends of the connection portion 11 are respectively connected to the two first ends 121, and the second end 122 is connected to the fixing portion 13. The abutting wall 112 is located at the connection portion 11. When the circuit board 200 is not assembled with the driving mechanism 300 (that is, the circuit board 200 is separated from the driving mechanism 300), the elastic main body portion 12 is in an uncompressed state; when the circuit board 200 is assembled with the driving mechanism 300, the elastic main body portion 12 is in a compressed state so that the abutting wall 112 abuts against the receiving wall 3021. Since the first ends 121 of the two elastic main bodies 12 are connected to the connecting part 11, and the two fixing parts 13 are fixedly connected to the circuit board 200, the two elastic main bodies 12 can balance the lateral force components generated when the two are deformed, and when the electrical connection unit 1 moves downward with the same displacement, a greater force can be exerted on the connecting part 11, thereby reducing the contact resistance.

[0035] From the second end 122 to the first end 121, the distance between the main body of the elastic main body 12 and the circuit board 200 gradually increases, and the main body of the elastic main body 12 protrudes in an oblique upward direction, that is, the main body of the elastic main body 12 is bent, so that the bent elastic main body 12 is easy to deform, so that when the connecting part 11 is abutted and connected with the driving mechanism 300, a force is provided to the connecting part 11. Since the main body of the elastic main body 12 at least partially protrudes toward the circuit board 200, the space occupied by the main body of the elastic main body 12 and the possibility of interference with other components are reduced.

[0036] The second end 122 of the elastic body 12 extends upward from the body of the elastic body 12; the circuit board 200 has a first fixing channel 202, and the first fixing channel 202 runs through the body of the circuit board 200. The fixing portion 13 is at least partially located in the first fixing channel 202 and is welded and fixed to the circuit board 200, specifically by soldering. In this way, the fixing portion 13 passes through the first fixing channel 202 of the circuit board 200 and is welded and fixed thereto, thereby ensuring the reliability of the fixation. By soldering, the fixing portion 13 is fixedly connected to the circuit board 200 and the electrical connection is achieved at the same time.

[0037] The electrical connection unit 1 includes an identification portion 2. In the vertical direction, the identification portion 2 is farther away from the receiving wall 3021 than the connecting portion 11. The identification portion 2 is fixed to the connecting portion 11. In the present embodiment, the identification portion 2 is rod-shaped. The circuit board 200 has a first accommodating channel 201. The first accommodating channel 201 passes through the body of the circuit board 200. The first accommodating channel 201 has a first opening 2011, and the first opening 2011 faces away from the driving mechanism 300. Part of the identification portion 2 is located in the first accommodating channel 201, and the identification portion 2 is slidably matched with the wall corresponding to the first accommodating channel 201. In some embodiments, the cross-sectional area of ​​the wall corresponding to the first accommodating channel 201 is larger than the cross-sectional area of ​​the identification portion 2. When the circuit board 200 is not assembled with the driving mechanism 300 (i.e., the circuit board 200 is separated from the driving mechanism 300), the identification portion 2 is not exposed from the first opening 2011, and the connecting portion 11 is separated from the driving mechanism 300; when the circuit board 200 is assembled with the driving mechanism 300, part of the identification portion 2 is exposed from the first opening 2011, and the connecting portion 11 abuts against the driving mechanism 300 to achieve electrical connection.

[0038] In this way, when the circuit board 200 is not assembled with the driving mechanism 300 (that is, the circuit board 200 is separated from the driving mechanism 300), the connecting portion 11 is separated from the driving mechanism 300, and the identification portion 2 is not exposed from the first opening 2011; when the circuit board 200 is assembled with the driving mechanism 300, the connecting portion 11 abuts against the driving mechanism 300 to achieve electrical connection, and part of the identification portion 2 is exposed from the first opening 2011, so that by observing whether the identification portion 2 is exposed from the first opening 2011, it can be determined whether the connecting portion 11 abuts against the driving mechanism 300 to achieve electrical connection.

[0039] The abutment wall 112 is a wall on the side of the connecting portion 11 facing the driving mechanism 300; the connecting portion 11 has a first side 111 facing away from the driving mechanism 300, one end of the identification portion 2 is fixed to the first side 111 (specifically, welded), and when the circuit board 200 is assembled with the driving mechanism 300, the abutment wall 112 abuts against the receiving wall 3021 to achieve electrical connection.

[0040] In this way, the connection portion 11 abuts against the driving mechanism 300 to achieve electrical connection and directly drives the identification portion 2 to move. Since the displacement at the connection portion 11 is the largest, more of the identification portion 2 is indirectly exposed from the first opening 2011 .

[0041] In this embodiment, the abutting wall 112 is a plane; in some embodiments, the abutting wall 112 is a curved surface convex toward the driving mechanism 300 .

[0042] Along the direction from the circuit board 200 to the driving mechanism 300 , the distance between the two sides of the first end 121 gradually decreases.

[0043] In this way, it is equivalent to having guide surfaces on both sides of the first end 121, so that during assembly, the connecting portion 11 can be guided into the corresponding area of ​​the driving mechanism 300 to achieve electrical connection.

[0044] The driving mechanism 300 has a receiving groove 301 with an opening toward the circuit board 200. The driving mechanism 300 includes an electrical connection terminal 302, which is located in the receiving groove 301. The receiving wall 3021 is the end surface of the electrical connection terminal 302 facing the circuit board 200. In the direction from the circuit board 200 to the driving mechanism 300, the projection of the connecting portion 11 is located on the bottom wall corresponding to the receiving groove 301.

[0045] In this way, the accommodating groove 301 provides a space for accommodating the electrical connection terminal 302 and also serves as a limit for the electrical connection terminal 302 ; and the electrical connection terminal 302 is used to abut against the connecting portion 11 to achieve electrical connection between the circuit board 200 and the driving mechanism 300 .

[0046] The accommodating groove 301 includes an accommodating section 3011 and a guiding section 3012, wherein the guiding section 3012 is farther away from the bottom wall corresponding to the accommodating groove 301 than the accommodating section 3011, and the electrical connection terminal 302 is located in the accommodating section 3011; in the direction of the driving mechanism 300 toward the circuit board 200, the spacing between the two side walls corresponding to the guiding section 3012 gradually increases; in the vertical direction, the minimum distance between the side wall corresponding to the guiding section 3012 and the bottom wall corresponding to the accommodating groove 301 is a, and the maximum distance between the electrical connection terminal 302 and the bottom wall corresponding to the accommodating groove 301 is b, and a is greater than b. In this way, after assembly, the connecting portion 11 is at least partially located in the accommodating section 3011, and the wall corresponding to the accommodating section 3011 has a blocking effect on the connecting portion 11.

[0047] In this way, the accommodating section 3011 is used to accommodate the electrical connection terminal 302, and the distance between the two side walls corresponding to the guide section 3012 gradually increases. During assembly, it plays a guiding role for the electrical connection unit 1, thereby facilitating the connection part 11 to enter the accommodating groove 301 and abut against the electrical connection terminal 302 to achieve electrical connection.

[0048] The electric control assembly also includes a main frame 3, which is fixedly connected to the circuit board 200; the main frame 3 includes at least one limiting accommodating portion 31, and the number of the limiting accommodating portions 31 is the same as the number of the electrical connection units 1; the electrical connection unit 1 is arranged in the limiting accommodating portion 31, and the limiting accommodating portion 31 includes at least one partitioning portion, and the number of the partitioning portions is the same as the number of the elastic main body 12. In the vertical direction, at least part of the limiting partitioning portion 311 is located between the elastic main body 12 and the circuit board 200; when the electrical connection unit 1 is in the first state, in the vertical direction, there is a gap between the elastic main body 12 and the limiting partitioning portion 311; when the electrical connection unit 1 is in the second state, in the vertical direction, part of the elastic main body 12 abuts against the second limiting partitioning portion 311 in the vertical direction. In this way, the first limiting partitioning portion 311 and the second limiting partitioning portion 311 play a limiting role on the electrical connection unit 1 to prevent it from excessive deformation.

[0049] The position-limiting accommodating portion 31 is provided with a second accommodating channel 313, which runs through the body of the position-limiting accommodating portion 31, and the second accommodating channel 313 is coaxially arranged with the first accommodating channel 201; part of the identification portion 2 is located in the second accommodating channel 313, and the identification portion 2 and the wall corresponding to the second accommodating channel 313 are slidably matched. In this embodiment, the number of the elastic main body portions 12 is two, that is, the number of the partitions is also two, and the second accommodating channel 313 is located between the two partitions. Since part of the identification portion 2 is located in the second accommodating channel 313, and the identification portion 2 and the wall corresponding to the second accommodating channel 313 are slidably matched, the wall corresponding to the second accommodating channel 313 plays a role in limiting the identification portion 2, thereby reducing its displacement.

[0050] A valve assembly includes a shell 100, at least one valve body 400 and the electronic control assembly in the above technical solution, the shell 100 has a accommodating cavity 101, the electronic control assembly is located in the accommodating cavity 101, the valve body 400 is at least partially located outside the shell 100, and the valve body 400 is penetrated by the driving mechanism 300.

[0051] FIG. 1 shows another embodiment. In this embodiment,

[0052] The electrical connection unit 1 includes an elastic main body 12, the position limiting accommodation portion 31 includes a partition, the main frame 3 includes at least one blocking portion 32, and the second accommodation channel 313 is located between the blocking portion 32 and the partition. In this way, when the connection portion 11 abuts against the driving mechanism 300, the elastic main body 12 deforms and generates a lateral force, and the blocking portion 32 blocks the identification portion 2 to prevent it from being deflected due to the lateral force.

[0053] In some embodiments, the electrical connection unit 1 does not include the identification portion 2, the connecting portion 11 is connected to the elastic main body portion 12, and in the vertical direction, the connecting portion 11 is closer to the receiving wall 3021 than the elastic main body portion 12, and the connecting portion 11 is used to abut against the receiving wall 3021 to achieve electrical connection between the electrical connection unit 1 and the driving mechanism 300.

[0054] It should be noted that: although this specification has described the present application in detail with reference to the above-mentioned implementation methods, ordinary technicians in the field should understand that technicians in the relevant technical field can still modify, combine or replace the present application with equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
