[0033] The present application provides a switch sealing structure to solve the problems in the related art that when potting a switch, the injection needle port needs to move around the metal insert, resulting in difficult injection sealing, low efficiency, and unstable injection quality.

[0034] Please refer to Figure 1 、 Figure 2 , a switch sealing structure, including an injection assembly 200 for injecting glue into the sealing part of the sealed switch 100. The sealed switch 100 includes a housing 110 and a metal insert 120, and the metal insert 120 is inserted into the housing 110. The injection assembly 200 includes an injection needle port 210, and an injection port 220 is opened on the injection needle port 210. The metal insert 120 can be inserted into the injection port 220, and an injection gap is provided between the injection port 220 and the metal insert 120.

[0035] Specifically, when using the sealing structure of this embodiment, the sealing switch 100 to be sealed and the metal insert 120 thereon are directly inserted into the injection port 220 on the injection needle port 210. After that, the injection assembly 200 can uniformly inject the sealing glue around the circumference of the metal insert 120 through the injection needle port 210. During the injection process, the injection needle port 210 does not need to move. After the sealing glue is injected, the metal insert 120 can be pulled out from the injection needle port 210.

[0036] In the related art, as Figure 3 , Figure 4 shown, the injection needle port 210 is usually a hollow cylindrical structure. When using the injection needle port 210 to inject glue for sealing the sealing switch 100, during the injection process, it is necessary to control the injection needle port 210 to slowly move circumferentially around the metal insert 120 so that the sealing glue can be evenly distributed around the circumference of the metal insert 120 to ensure the sealing effect between the metal insert 120 and the housing 110. The need to move during the injection process not only results in low injection efficiency, but also, affected by the actual working environment and the operator's manual operation, leads to high injection difficulty and unstable injection quality.

[0037] The injection assembly 200 provided in this embodiment can, when in use, simultaneously and uniformly inject the sealing glue around the circumference of the metal insert 120 through the injection needle port 210, and there is no need to control the injection needle port 210 to move around the metal insert 120 during the injection process. The injection process can be controlled by manual or automated equipment, with low injection difficulty and high efficiency. In addition, since the metal insert 120 is completely enclosed in the injection needle port 210, the injection process will not be affected by the external environment. Without the need for the injection needle port 210 to move, the influence of the operator on the injection process can also be minimized, effectively ensuring the stable quality of the injection sealing in this embodiment.

[0038] In some embodiments, by way of example, as Figure 1 , Figure 2 shown, a sealing groove 130 is formed on the housing 110. The sealing groove 130 is provided at the connection between the housing 110 and the metal insert 120 and is arranged around the metal insert 120. In the mating connection between the housing 110 and the metal insert 120, the provision of the sealing groove 130 can ensure a firm and good sealing performance between the two.

[0039] When entering the injection sealing process, the operator uses the injection equipment to inject the sealing glue through the injection needle port 210. Due to the presence of the sealing groove 130, the sealing glue can accurately flow into the preset position, that is, into the sealing groove 130, rather than spreading randomly to other areas of the housing 110. This effectively controls the flow range of the sealing glue, avoids unnecessary waste and contamination of the housing 110, and can also significantly improve the cleanliness and operation efficiency of the production site.

[0040] After the sealant enters the seal groove 130, it will quickly fill and cure to form a strong and continuous sealing barrier, ensuring that the contact surface between the housing 110 and the metal insert 120 fits tightly, effectively blocking the intrusion of moisture, dust, and corrosive substances in the external environment. It can also relieve the small displacements that may be caused by temperature changes or mechanical vibrations through the elasticity and adhesion of the sealant, further enhancing the stability and durability of the connection.

[0041] In addition, the design that the sealant completely stays in the seal groove 130 also cleverly utilizes the physical properties of the material, such as good sealing performance, weather resistance, and anti-aging property, to further improve the sealing effect of the overall structure. This not only ensures the sealing ability of this embodiment under extreme working conditions but also extends the service life of the product and reduces the later maintenance cost.

[0042] In some embodiments, by way of example, such as Figure 1 、 Figure 2 shown, the cross-sectional shape of the glue injection needle opening 210 is the same as the shape of the seal groove 130. The glue injection needle opening 210 is aligned with the preset seal groove 130 to ensure the accurate execution of the glue injection operation. In the subsequent glue injection process, the sealant flows accurately into the seal groove 130 from the glue injection needle opening 210 through the glue injection assembly 200.

[0043] As the sealant continues to be injected, the seal groove 130 is gradually filled. This process is continuous and uniform, ensuring the consistency and integrity of the sealing layer. When the space in the seal groove 130 is completely occupied by the sealant, the operator can control to stop the glue injection action to avoid the waste and inconvenience that may be caused by over-injection.

[0044] The glue injection and filling process of this embodiment not only ensures that the seal groove 130 can be filled completely and tightly with the sealant but also greatly improves the reliability and durability of the sealing effect. After the sealant cures in the seal groove 130, a sealing barrier can be formed to effectively block adverse factors such as moisture, dust, and corrosive substances in the external environment, protecting the integrity and functional stability of the internal structure of the sealed switch 100. At the same time, the good sealing effect also improves the overall performance and service life of the product, ensuring the use experience of the sealed switch 100.

[0045] In some embodiments, by way of example, such as Figure 1 、 Figure 2 shown, multiple metal inserts 120 are provided on the housing 110, and seal grooves 130 are opened on the housing 110 at each metal insert 120. According to the actual situation, any number of metal inserts 120 can be provided on the housing 110. When sealing the metal inserts 120, only need to sleeved the glue injection needle opening 210 on the metal inserts 120 in turn and perform glue injection sealing until the seal groove 130 is filled with the sealant.

[0046] In this embodiment, when assembling the metal insert 120 and the housing 110, a sealing groove 130 is formed on the housing 110, and the metal insert 120 is inserted into the sealing groove 130. This not only enables the sealant to be filled into the sealing groove 130, improving the sealing effect, but also can assist in positioning the metal insert 120 through the sealing groove 130, further reducing the production and processing difficulty of this embodiment.

[0047] In some embodiments, by way of example, such as Figure 1 、 Figure 2 As shown, the injection assembly 200 further includes a fixing plate, and a plurality of injection needle ports 210 are provided on the fixing plate. Specifically, a plurality of injection needle ports 210 are provided on the fixing plate, and the positions of the injection needle ports 210 can be correspondingly set according to the positions of the metal inserts 120 on the housing 110, so that the plurality of injection needle ports 210 are accurately inserted into a one-to-one correspondence with the plurality of metal inserts 120. When performing the injection sealing operation on the sealed switch 100, the operator only needs to accurately position the injection assembly 200 so that each injection needle port 210 on the assembly can accurately correspond to the position of the metal insert 120 on the fixing plate. Subsequently, through a one-time synchronous operation, the plurality of metal inserts 120 can be quickly and firmly inserted into their respective corresponding injection needle ports 210 to form a stable injection connection system. At this time, the injection assembly 200 is activated, and the sealant is simultaneously injected from each injection needle port 210 and accurately filled into the injection gap between each metal insert 120 and the injection needle port 210.

[0048] In this embodiment, the parallel injection process can shorten the injection time of a single sealed switch 100, and can also significantly improve the overall production efficiency by reducing the operation steps and waiting time. At the same time, since all injection operations are almost carried out simultaneously, it also ensures the uniformity and consistency of the injection amount between the metal inserts 120, further improving the sealing quality and reliability of the product.

[0049] It should be noted that the number and positions of the injection needle ports 210 on the fixing plate can be adaptively adjusted according to the number and positions of the metal inserts 120 on the housing 110 to make them correspond and match.

[0050] In addition, it can be understood that a flow channel is formed in the fixing plate, and the flow channel is in communication with the injection ports 220 in the plurality of injection needle ports 210. When using this embodiment for the injection sealing operation, a connecting member can be provided on the fixing plate to connect the flow channel in the fixing plate with the storage member of the external sealant, so that this embodiment can be used normally to simultaneously perform the injection sealing operation on the sealing grooves 130 near the plurality of metal inserts 120.

[0051] In some embodiments, by way of example, such as Figure 1, Figure 2 As shown in the figure, a plugging surface 111 is provided on the housing 110. The plugging surface 111 is set as a flat surface, and a plurality of metal inserts 120 are all vertically plugged on the plugging surface 111. A plurality of glue injection needle ports 210 are all vertically arranged on the fixing plate. By restricting the relative positions of the housing 110 and the metal inserts 120, the connection between the metal inserts 120 and the housing 110 is made regular, reducing the sealing difficulty. During use, the vertically arranged metal inserts 120 and the vertically arranged glue injection needle ports 210 can ensure that the glue injection needle ports 210 and the metal inserts 120 can be stably and reliably matched, and the plugging and matching process is made simpler and more convenient.

[0052] Furthermore, during the glue injection and sealing operation, usually the glue injection assembly 200 is arranged above the sealing switch 100, and the glue injection needle ports 210 and the metal inserts 120 are both vertically arranged, which can make the sealant be affected by the gravity during the sealant injection process, making the glue injection process more stable and smooth, and ensuring the stability during the use of this embodiment.

[0053] In some embodiments, by way of example, such as Figure 1 , Figure 2 As shown in the figure, the metal insert 120 is set as a rectangular plate, and a guiding section 121 is provided at one end of the metal insert 120 away from the housing 110. The regular shape of the rectangular plate ensures the stability and predictability of the glue injection operation, and makes the processing of the glue injection needle ports 210 simpler and faster. Without complex positioning and adjustment, production and processing can be achieved, reducing the production and processing difficulty.

[0054] In order to further reduce the technical threshold and operation difficulty during the assembly process, a guiding section 121 is added to the metal insert 120. A bevel structure is provided on the guiding section 121. When the metal insert 120 approaches and attempts to insert into the glue injection needle port 210, the bevel can guide and assist the metal insert 120 to smoothly slide into the predetermined position. Even if there is a slight collision or misalignment between the bevel of the insert and the edge of the needle port, the bevel can automatically adjust the direction through its geometric characteristics to ensure that the insert can accurately slide into the interior of the needle port to complete the assembly.

[0055] In some embodiments, by way of example, such as Figure 1 , Figure 2 As shown in the figure, the distance between the guiding section 121 and the housing 110 is L1, and the length of the glue injection needle port 210 is L2, satisfying: L2 > L1. The distance between the guiding section 121 and the housing 110, that is, the distance of the metal insert 120, restricts the lengths of the metal insert 120 and the glue injection needle port 210, making the length of the glue injection needle port 210 greater than the length of the metal insert 120, which can ensure that the smoothness of the glue injection port 220 will not be affected by the metal insert 120 when the glue injection needle port 210 injects glue to seal the connection, and ensure that the sealant can flow normally and smoothly.

[0056] In some embodiments, by way of example, such as Figure 1 , Figure 2 As shown, the cross-section of the glue injection port 220 is set as a rectangle, and the glue injection gap is correspondingly set as a rectangular frame, and the thickness at any side of the rectangular frame is equal. The cross-section of the glue injection port 220 and the metal insert 120 are both set as rectangles. The regularized shape makes the production difficulty of this embodiment lower, and the glue injection gap between the glue injection port 220 and the metal insert 120 is easier to control, further reducing the production and processing difficulty of this embodiment.

[0057] This application also provides a sealed switch 100, and the sealed switch 100 is sealed by the switch sealing structure in any one of the above embodiments; the sealed switch 100 further includes an opening and closing assembly, and the opening and closing assembly is electrically connected to the metal insert 120.

[0058] The sealed switch 100 of this embodiment can be sealed by the switch sealing structure in any one of the above embodiments, and thus has all the beneficial effects described in the above embodiments, which will not be elaborated here.

[0059] The sealed switch 100 includes a metal insert 120, a housing 110 and an opening and closing assembly. The metal insert 120 and the opening and closing assembly are both assembled on the housing 110. When using the sealed switch 100 of this embodiment, the sealed switch 100 is assembled at a suitable position on the motorcycle, and the multiple metal inserts 120 on the housing 110 are sequentially connected to the target positions, and then the sealed switch 100 can be controlled by the opening and closing assembly. When the opening and closing assembly is closed, that is, the motorcycle electrical control system is normally connected, and the motorcycle can work normally. When the opening and closing assembly is disconnected, that is, the motorcycle electrical control system is disconnected, and the motorcycle stops working.

[0060] It can be understood that the sealed switch 100 provided in this embodiment is not limited to being applied to motorcycles, and any electrical appliance that requires a switch and is adapted to this embodiment can be used.

[0061] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
