Description

Technical Field

[0001] This utility model relates to the field of sealing mechanism technology, and in particular to a sealing mechanism for the lead-out hole of the wire in the housing of an electric vehicle controller. Background Technology

[0002] The baffles of the electric vehicle controller housing are all machined with wire lead-out holes to facilitate the passage of wires. Each wire lead-out hole is equipped with a sealing mechanism. In traditional sealing mechanisms, the locking head and the sealing gasket are each an independent part, requiring two molds during production, which results in higher equipment investment and production costs.

[0003] The existing publication number CN203258203U discloses a sealing mechanism for a wire lead-out hole on an electric vehicle controller housing. It includes a sealing gasket, which is a flexible sheet. Its key feature is a flexible sealing head on one side of the sealing gasket. The flexible sealing head is a short tube, one end of which is integrally formed with the sealing gasket. A wire lead-out hole is located on the sealing gasket, corresponding to the inner diameter of the flexible sealing head. The outer circumference of the end of the flexible sealing head connected to the sealing gasket has a circumferential groove that facilitates mating with the wire lead-out hole on the electric vehicle controller housing baffle. The diameter of the bottom of the circumferential groove is equal to or larger than that of the wire lead-out hole on the electric vehicle controller housing baffle. This sealing mechanism has low production cost, simple structure, and high production efficiency. It is suitable for sealing the wire lead-out hole on the electric vehicle controller housing baffle and the sealing head.

[0004] However, the diameter of the bottom of the circumferential groove of the sealing mechanism for the wire lead-out hole of the electric vehicle controller housing is equal to or larger than the wire lead-out hole on the baffle of the electric vehicle controller housing. It is relatively small, and it is impossible to determine whether the installation is in place. If the installation is not in place, it may lead to poor sealing. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing mechanism for the wire lead-out hole of the electric vehicle controller housing, which solves the problem that it is impossible to determine whether the installation is in place, and if the installation is not in place, it may lead to poor sealing.

[0006] To achieve the above objectives, this utility model provides a sealing mechanism for the wire lead-out hole of an electric vehicle controller housing, including a sealing gasket, a flexible sealing head on one side of the sealing gasket, the flexible sealing head being a short tube with one end integrally formed with the sealing gasket, the sealing gasket having a wire lead-out hole corresponding to the inner diameter of the flexible sealing head, and a guide component.

[0007] The guide assembly includes a plug and a locking member. The plug is fixedly connected to the sealing gasket and is located on the side of the sealing gasket near the outer casing baffle. The locking member is connected to the outer casing baffle, which has a socket corresponding to the plug.

[0008] The locking component includes a connecting spring and a plug. The plug is slidably connected to the outer casing baffle and is located on the side of the outer casing baffle near the plug rod. The two ends of the connecting spring are respectively connected to the plug and the outer casing baffle.

[0009] The insertion rod has a locking groove that engages with the insertion block.

[0010] The sealing mechanism for the lead wire outlet hole of the electric vehicle controller housing also includes a sealing ring. The sealing ring is fixedly connected to the housing baffle and is located at the lead wire outlet hole of the housing baffle. The flexible sealing head has a groove that cooperates with the sealing ring.

[0011] The sealing mechanism for the wire lead-out hole of the electric vehicle controller housing also includes multiple fan-shaped pieces. The arc-shaped edges of the multiple fan-shaped pieces are integrated with the periphery of the wire lead-out hole on the sealing gasket, and the adjacent edges of the adjacent fan-shaped pieces are in contact when not in use.

[0012] This utility model discloses a sealing mechanism for the lead-out hole of the wire in the housing of an electric vehicle controller. The sealing gasket is installed on the housing baffle through the guide of the plug rod and the plug hole. Then, the locking member is engaged with the plug rod to lock it. The plug rod and the plug hole help to quickly align during installation and reduce installation errors. The locking member improves the stability of the installation, thereby enhancing the sealing effect and avoiding the effect of poor sealing caused by improper installation.

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] The first embodiment of this application is as follows:

[0021] Please see Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of the sealing mechanism for the lead wire outlet hole of the electric vehicle controller housing according to the first embodiment of this utility model. Figure 2 This is a cross-sectional structural schematic diagram of the sealing mechanism for the lead wire outlet hole of the electric vehicle controller housing according to the first embodiment of this utility model.

Figure 4 This is the utility model Figure 3 Enlarged view of point A.

[0022] This utility model provides a sealing mechanism for the lead-out hole of the wire in the housing of an electric vehicle controller: it includes a sealing gasket 101, a guide assembly, a sealing ring 108, and multiple sector-shaped pieces 110. The guide assembly includes a plug rod 103 and a locking member. The housing baffle 100 has a plug hole 104. The locking member includes a connecting spring 105 and a plug block 106. The plug rod 103 has a locking groove 107. The aforementioned solution solves the problem of not being able to determine whether the installation is in place, which may lead to poor sealing if the installation is not in place. It is understood that the aforementioned solution can also be used to solve the problem of enhancing the sealing effect.

[0023] In this specific embodiment, the sealing gasket 101 has a flexible sealing head 102 on one side. The flexible sealing head 102 is a short tube, one end of which is integrally formed with the sealing gasket 101. The sealing gasket 101 has a wire lead-out hole corresponding to the inner diameter of the flexible sealing head 102. Both the sealing gasket 101 and the flexible sealing head 102 have been disclosed in publication number CN203258203U. The outer circumference of the end of the flexible sealing head 102 connected to the sealing gasket 101 has a circumferential groove 109 that facilitates matching with the wire lead-out hole on the electric vehicle controller housing baffle 100. This is prior art and will not be described in detail here.

[0024] The insertion rod 103 is fixedly connected to the sealing gasket 101 and located on the side of the sealing gasket 101 near the outer shell baffle 100. The locking member is connected to the outer shell baffle 100, which has an insertion hole 104 corresponding to the insertion rod 103. There may be one or more insertion rods 103, which can be integrally formed with the sealing gasket 101 and fixed to one side of the sealing gasket 101. They cooperate with the insertion hole 104 on the outer shell baffle 100 of the electric vehicle controller, inserting into the insertion hole 104 to provide installation guidance and reduce installation errors. The locking member is located inside the outer shell baffle 100 to lock the insertion rod 103, improving installation stability.

[0025] Secondly, the insert block 106 is slidably connected to the outer shell baffle 100 and is located on the side of the outer shell baffle 100 near the insert rod 103. The two ends of the connecting spring 105 are respectively connected to the insert block 106 and the outer shell baffle 100. One or more locking members are provided around each insert rod 103. The connecting spring 105 pushes the insert block 106 to slide inside the outer shell baffle 100. The two sides of the insert block 106 that contact the insert rod 103 are respectively arc-shaped or steeply sloped, so that it can slide into the outer shell baffle 100 under force when in contact.

[0026] Meanwhile, the insertion rod 103 has a locking groove 107, which engages with the insertion block 106. After the insertion rod 103 is inserted into the insertion hole 104, the locking groove 107 aligns with the insertion block 106. Under the elastic force of the connecting spring 105, the insertion block 106 engages into the locking groove 107, locking the insertion rod 103 so that it can only be unlocked when the insertion rod 103 receives an outward pulling force.

[0027] In addition, the sealing ring 108 is fixedly connected to the outer shell baffle 100 and located at the wire lead-out hole of the outer shell baffle 100. The flexible sealing head 102 has a groove 109, which mates with the sealing ring 108. Multiple sealing rings 108 are present, and each sealing ring 108 is respectively engaged within the groove 109 to enhance the sealing effect.

[0028] Finally, the arc-shaped edges of the plurality of sector-shaped pieces 110 are integrated with the periphery of the wire lead-out holes on the sealing gasket 101, and in the non-use state, the adjacent edges of the adjacent sector-shaped pieces 110 are in contact. The sector-shaped pieces 110 are those disclosed in publication number CN203258203U, which tightly fit around the periphery of the wire when the wire passes through, thus playing a sealing role.

[0029] Using the sealing mechanism for the wire lead-out hole of the electric vehicle controller housing according to this embodiment, during installation, the insertion rod 103 is aligned with the insertion hole 104, and the front end of the flexible sealing head 102 is inserted into the wire lead-out hole from under the electric vehicle controller housing baffle 100 and pressed by hand, so that the wire lead-out hole of the outer frame baffle is engaged in the circumferential groove 109 on the flexible sealing head 102. At the same time, the insertion rod 103 is inserted into the insertion hole 104, and the connecting spring 105 pushes the insertion block 106 to engage in the engagement groove 107. The sealing ring 108 engages in the groove 109. With the guidance of the insertion rod 103 and the insertion hole 104, the alignment is quick during installation, reducing installation errors. The insertion block 106 and the engagement groove 107 improve the stability of the connection, and the sealing ring 108 enhances the sealing effect. Thus, the sealing effect caused by improper installation is avoided.

[0030] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
