[0037] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0038] Please refer to Figure 1-Figure 8The push switch assembly structure 100 and the electrical appliance provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.

[0039] refer to Figure 1-Figure 4 The push switch assembly structure 100 is used for an electrical appliance, and includes a push member 120, a housing 110, and a flexible seal 130; wherein a push hole 112 is formed on the housing 110, and the push member 120 includes a push bracket 121 and a push head 122, and the push bracket 121 is used to fix the push head 122 and allow the push head 122 to be accommodated in the push hole 112;

[0040] The flexible sealing member 130 is used to seal the pressing hole 112 . The flexible sealing member 130 can be deformed under the action of an external force and squeeze the pressing head 122 .

[0041] When the push switch assembly structure 100 is in working state, the push head 122 is accommodated in the push hole 112, and the flexible seal 130 can not only squeeze the push head 122 but also seal the push hole 112 to prevent water droplets or impurities from entering. When the shape and height of the housing 110 change, the push piece 120 can still be used, and there is no need to re-open the mold of the push piece 120 according to the change of the housing 110, thereby improving versatility and reducing manufacturing costs.

[0042] A positioning portion is also formed on the shell 110, which protrudes from the inner wall surface 119 of the shell 110, is perpendicular to the inner wall surface 119 and parallel to the mold opening direction of the shell 110, and is used to resist the pressing bracket 121, which can make the positioning structure relatively simple and easy to demold. It can also adapt to shells 110 with various curved surface structures. Only the matching height of the positioning portion needs to be changed, and the pressing bracket 121 does not need to be changed, thereby improving the versatility of the overall assembly structure.

[0043] It is worth noting that the housing 110 can be understood as the entire housing of the electrical appliance to which the push switch assembly structure 100 is applied, or it can be a partial housing. In addition, the end of the push head 122 close to the flexible seal 130 can be flush with the opening of the push hole 112, or can be set lower than the opening of the push hole 112, so that the end of the push head 122 can be protected by the push hole 112. The flexible seal 130 seals the push hole 112 to prevent water droplets and dust impurities from entering the push hole 112 and causing negative effects.

[0044] In this embodiment, the pressing head 122 is a micro switch, which has a small contact spacing and a snap-action mechanism, and a contact mechanism that performs a switching action with a specified stroke and a specified force. Because the contact spacing of the switch is relatively small, it is called a micro switch, and it can also be called a sensitive switch.

[0045] Of course, in other embodiments of the present invention, the pressing head 122 may also be other mechanisms that achieve signal transmission through a pressing action.

[0046] refer to Figure 5 and Figure 6 The positioning portion includes a positioning rib 111 , and the pressing bracket 121 has a first side plate 1211 and a second side plate 1212 that are arranged opposite to each other. The positioning rib 111 is used to abut against the end surface of the first side plate 1211 and / or the second side plate 1212 .

[0047] In this embodiment, the number of the positioning ribs 111 is two, and the two positioning ribs 111 are parallel to each other and respectively abut against the first side plate 1211 and the second side plate 1212 to ensure the positioning stability of the pressing bracket 121. Of course, in other embodiments of the present invention, the number of the positioning ribs 111 can also be one, three, five, etc., and the multiple positioning ribs 111 can be parallel or staggered, and the specific number and relative relationship of the positioning ribs 111 are not limited.

[0048] refer to Figure 5-Figure 8 In order to enhance the limiting effect of the shell 110 on the pressing bracket 121 and prevent the pressing bracket 121 from rotating relative to the shell 110 after being subjected to external force, the positioning portion may further include a limiting rib 113, and a limiting groove 126 may be formed on the pressing bracket 121, and the limiting rib 113 may be accommodated in the limiting groove 126 to limit the pressing bracket 121.

[0049] In this embodiment, the number of the limiting grooves 126 and the limiting ribs 113 are both two, and the two limiting ribs 113 are respectively accommodated in the two limiting grooves 126, and the two limiting grooves 126 are respectively located near the two sides of the pressing bracket 121. Of course, in other embodiments of the utility model, the number of the limiting grooves 126 and the limiting ribs 113 can also be one, three, five groups, etc., and there is no limitation on the specific number and location of the limiting grooves 126 and the limiting ribs 113.

[0050] refer to Figure 6 The positioning portion further includes a pressing rib 115 , and the pressing bracket 121 has a third side plate 1213 . The pressing rib 115 is used to abut against the end surface and side surface of the third side plate 1213 to press the pressing bracket 121 .

[0051] Specifically, the compression rib 115 has a first compression surface 1151 and a second compression surface 1152 which are arranged at an angle. The first compression surface 1151 is used to abut against the end surface of the third side plate 1213 , and the third side plate 1213 is abutted between the second compression surface 1152 and the inner wall surface 119 .

[0052] In this embodiment, the two ends of the third side plate 1213 are respectively connected to the first side plate 1211 and the second side plate 1212, and the third side plate 1213 is perpendicular to the first side plate 1211 and the second side plate 1212 at the same time; the first pressing surface 1151 and the second pressing surface 1152 also remain perpendicular.

[0053] During the assembly process, the second pressing surface 1152 is spaced from the inner wall surface 119 and forms an accommodating cavity, which allows the third side plate 1213 to move toward the cavity, and the third side plate 1213 first contacts the second pressing surface 1152 to be tightly pressed between the second pressing surface 1152 and the inner wall surface 119, and then contacts the first pressing surface 1151. The first pressing surface 1151 limits the third side plate 1213, and the contact indicates that the third side plate 1213 has reached the assembly position.

[0054] refer to Figure 7 and Figure 8 The pressing member 120 further includes a circuit board 123, the circuit board 123 is mounted on the pressing bracket 121, and the pressing head 122 is electrically connected to the circuit board 123. That is, one end of the pressing head 122 away from the flexible sealing member 130 is electrically connected to the circuit board 123. In addition, the pressing member 120 further includes a connector 124, which is spaced apart from the pressing member 120 and electrically connected to the circuit board 123. The connector 124 is also used to connect a wiring harness, and the transmission and conversion of switch signals can be realized through the wiring harness, the connector 124 and the circuit board 123.

[0055] refer to Figure 7 and Figure 8 In order to improve the installation stability of the circuit board 123, a buckle portion 125 may be formed on the pressing member 120, and the buckle portion 125 is buckled and matched with the circuit board 123. Specifically, the buckle portion 125 is connected to the pressing bracket 121.

[0056] Specifically, the buckle portion 125 extends from the bottom of the pressing bracket 121 toward one side and forms an undercut structure. The buckle portion 125 has a certain elasticity. During the process of placing the circuit board 123, the buckle portion 125 can be squeezed to deform, so that the buckle portion 125 can store elastic potential energy; when the circuit board 123 is placed in a suitable position, the buckle portion 125 is no longer squeezed, and the buckle portion 125 releases elastic potential energy to reset, so that the undercut structure is located on one side of the circuit board 123, thereby ensuring that the circuit board 123 is clamped on the pressing bracket 121, and the circuit board 123 will not easily fall off the pressing bracket 121.

[0057] In this embodiment, there is one snap-fit ​​portion 125, which is used to snap-fit ​​with the middle position of one side of the circuit board 123; of course, the number of snap-fit ​​portions 125 can also be two, three, five, etc., and multiple snap-fit ​​portions 125 can snap-fit ​​with different positions of the circuit board 123 respectively.

[0058] refer to Figure 4-Figure 8 In order to further improve the relative position stability, a locking portion 127 may be formed on the pressing member 120, and the pressing switch assembly structure 100 further includes a locking member 140, which penetrates the housing 110 and cooperates with the locking portion 127 to lock the pressing bracket 121. Specifically, the locking portion 127 is connected to the pressing bracket 121.

[0059] Furthermore, in order to avoid damage to the circuit board 123, a corresponding first locking hole 128 may be provided on the circuit board 123. Similarly, a corresponding second locking hole 114 may be provided on the shell 110. The two locking holes are used to avoid the locking portion 127 or the locking member 140 respectively.

[0060] In this embodiment, the locking portion 127 is a cylindrical structure with a central hole protruding from the pressing bracket 121, wherein the hole is a screw hole, and the locking member 140 is a stud, which is threadedly connected to the screw hole and utilizes the self-locking property of the threaded connection to fully ensure the relative position stability of the pressing bracket 121 and the shell 110.

[0061] Of course, in other embodiments of the present invention, the center hole on the locking portion 127 may also be a light hole, and the locking member 140 may be an optical axis, and the optical axis and the light hole are interference fit, thereby locking the pressing bracket 121 and the shell 110.

[0062] It should be noted that the number of the locking portion 127, the locking member 140, the first locking hole 128 and the second locking hole 114 in this embodiment is one; of course, in other embodiments of the present invention, the number of the locking portion 127, the locking member 140, the first locking hole 128 and the second locking hole 114 can also be two, three, five, etc., and the specific number is not limited.

[0063] The embodiment of the utility model further provides an electrical appliance, including a push switch assembly structure 100. The electrical appliance can be an industrial appliance or a household appliance, and can specifically be a charging pile, a water heater, etc., and its specific type is not limited.

[0064] Taking the charging pile as an example, the charging pile also includes an input module, an output module, and a master control module. The input module and the output module communicate with the master control module. At the same time, the circuit board 123 in the push switch assembly structure 100 also communicates with the master control module to control the working state of the master control module. The electrical appliance includes the push switch assembly structure 100, which has all the functions of the push switch assembly structure 100.

[0065] In summary, the push switch assembly structure 100 and the electrical appliance provided by the embodiment of the present invention have at least the following advantages:

[0066] (1) When the shape and height of the housing 110 of the push switch assembly structure 100 change, the push member 120 can still be used without having to re-mold the push member 120 according to the change of the housing 110, thereby improving versatility and reducing manufacturing costs.

[0067] (2) The push switch assembly structure 100 is provided with matching limiting grooves 126 and limiting ribs 113 to enhance the limiting effect of the housing 110 on the push bracket 121, thereby preventing the push bracket 121 from rotating relative to the housing 110 after being subjected to external force.

[0068] (3) The push switch assembly structure 100 further improves the relative position stability between the push bracket 121 and the housing 110 by providing a locking portion 127 and utilizing the locking portion 127 to cooperate with a locking member 140 that penetrates the housing 110 .
