Detailed Implementation
[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0022] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, and "at least one" can mean one, two, or more, unless otherwise explicitly specified.
[0023] As an important automotive component, this product generally requires waterproofing and dustproofing. Currently, airtightness testing is typically conducted using a volumetric method. This involves sealing the connector opening at one end of the product (the product usually has a connector at one end, and the connector's internal space is connected to the product's internal space) with a plug to prevent the gas used for testing from flowing through the opening. However, during airtightness testing, the plug may loosen due to other factors (such as the pressure of the introduced gas or vibration of the testing equipment), or even be pushed out by the gas inside the connector, preventing the plug from effectively sealing the connector opening.
[0024] In view of this, embodiments of this application provide a sealing device to overcome at least one of the above-mentioned technical problems.
[0025] Please see Figure 1 and Figure 2 In this embodiment of the application, the sealing device is used to seal the connector 30 at one end of the product 70. The connector 30 has an opening 31 arranged along the first direction X. The sealing device includes a first support member 10, a second support member 20 and a sealing member 40.
[0026] The first support member 10 is disposed on one side of the second support member 20 along the second direction Y, and is movable relative to the second support member 20 along the second direction Y. The first direction X and the second direction Y intersect, preferably, the first direction X and the second direction Y are perpendicular to each other. A pushing part 11 is provided on the side of the first support member 10 facing the second support member 20. The connector 30 is located on the side of the second support member 20 facing the first support member 10 and is connected to the second support member 20. The sealing member 40 is located on the side of the second support member 20 facing the first support member 10 and is slidably connected to the second support member 20. The pushing part 11 is used to push the sealing member 40 to slide along the first direction X to cover the opening 31.
[0027] It is understood that one or both of the first support member 10 and the second support member 20 can be moved along the second direction Y by a lifting structure, which can be a hydraulic lift or an electric lift, etc. When sealing the opening 31 of the connector 30, the product 70 can be placed on the side of the second support member 20 facing the first support member 10. The product 70 can be fixedly connected to the second support member 20 by a snap-fit structure or a bolt structure, thereby ensuring that the product 70 has a certain degree of stability. The sealing member 40 is also placed on the side of the second support member 20 facing the first support member 10, and is located on the side of the connector 30 along the first direction X, corresponding to the opening 31 on the connector 30; at the same time, the sealing member 40 can also slide along the first support member 10 along the first direction X, and the sealing member 40 can seal or release the opening 31 by sliding. By providing a pushing part 11 on the side of the first support member 10 facing the second support member 20, when the first support member 10 moves towards the second support member 20 along the second direction Y, the first support member 10 can drive the pushing part 11 to squeeze and push the sealing member 40, causing the sealing member 40 to move towards the opening 31 on the connector 30 until the sealing member 40 seals the opening 31. Alternatively, the first support member 10 and the second support member 20 have a first state and a second state. In the first state, the first support member 10 and the second support member 20 are spaced apart along the second direction Y (e.g., ...). Figure 1 In the second state, the first carrier 10 and the second carrier 20 are interconnected (e.g., Figure 2 In the second state, the pushing part 11 continuously compresses the sealing member 40, causing the sealing member 40 to press against the connector 30, ensuring that the sealing member 40 remains sealed at the opening 31 and maintains a tight connection, preventing the gas used for detection from flowing through the opening 31 of the connector 30. The pushing part 11 can continuously compress the sealing member 40 to prevent the sealing member 40 from loosening when sealing the opening 31, ensuring the sealing effect of the sealing member 40 on the opening 31.
[0028] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the second carrier 20 is provided with a fixing part 21 on the side facing the first carrier 10. The fixing part 21 is provided on the side of the connector 30 along the first direction X, and the opening 31 is provided facing the fixing part 21. The fixing part 21 has a guide hole 211 opened along the first direction X, and the sealing member 40 passes through the guide hole 211.
[0029] Understandably, to ensure that the sealing component 40 can move along the first direction X, a fixing part 21 can be provided on the side of the second support component 20 facing the first support component 10. The fixing part 21 can be a block-shaped structure, connected to the second support component 20 by welding or bolting to ensure stability. A guide hole 211 is formed through the fixing part 21, extending along the first direction X. The sealing component 40 can pass through the guide hole 211 and slide within it. The guide hole 211 guides the sliding of the sealing component 40, ensuring that the sealing component 40 can slide along the first direction X under the action of the pushing part 11, thereby sealing the opening 31 and improving the accuracy of the alignment between the sealing component 40 and the opening 31.
[0030] Please see Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the second carrier 20 includes an elastic portion 22. The elastic portion 22 is located inside the guide hole 211 and is disposed around the sealing member 40. One end of the elastic portion 22 along the first direction X abuts against the sealing member 40, and the other end of the elastic portion 22 along the first direction X abuts against the fixing portion 21.
[0031] It is understandable that an elastic part 22 can be provided in the guide hole 211, such that one end of the elastic part 22 abuts against the sealing member 40 and the other end abuts against the fixing part 21 (or abuts against the inner wall of the guide hole 211). The elastic part 22 can be a spring, a sheet, or other structure with a certain elasticity. With the elastic part 22 provided, when the pushing part 11 pushes the sealing member 40, the moving sealing member 40 will squeeze the elastic part 22, causing the elastic part 22 to deform to a certain extent. When the pushing part 11 is moved and the squeezing force on the sealing member 40 is removed, the elastic part 22 will also lose the squeezing force of the sealing member 40, thereby restoring its deformation and pushing the sealing member 40 in the opposite direction, causing the sealing member 40 to move in the opposite direction and return to its original position, releasing the sealing effect on the opening 31, without the need for manual adjustment of the sealing member 40 to its original position.
[0032] Please see Figure 8 , Figure 9 and Figure 10 In conjunction with the above embodiments, in some embodiments, the sealing member 40 includes a guide portion 41, a pressing portion 42, and a sealing portion 43.
[0033] The guide portion 41 passes through the guide hole 211 and is slidably connected to the fixing portion 21. The pushing portion 11 is used to push the guide portion 41 to move along the first direction X. The pressing portion 42 is located on the side of the guide portion 41 facing the connector 30 and is connected to the guide portion 41. The sealing portion 43 is located on the side of the pressing portion 42 facing the connector 30 and is connected to the pressing portion 42. The sealing portion 43 is used to cover the opening 31.
[0034] Understandably, the guide portion 41 on the sealing member 40 can pass through the guide hole 211 and form a sliding fit with the guide hole 211, so that the entire sealing member 40 can slide along the first direction X under the push of the push portion 11. The guide portion 41 can be configured as a rod-shaped structure to facilitate passing through the guide hole 211. The guide portion 41 can also be provided with a protruding structure for abutting against the elastic portion 22. When the guide portion 41 moves, the protruding structure can squeeze the elastic portion 22. A squeezing portion 42 can be provided on the side of the guide portion 41 facing the connector 30. The guide portion 41 drives the squeezing portion 42 to squeeze and seal the opening 31. To further improve the sealing effect of the sealing component 40 on the opening 31, a sealing part 43 can be provided on the side of the extrusion part 42 facing the connector 30. The sealing part 43 can be made of materials with good sealing effect, such as rubber or silicone. The extrusion part 42 covers and compresses the opening through the sealing part 43, which can improve the sealing effect of the sealing component 40 on the opening 31 and prevent gas from entering the connector 30 through the opening 31 or gas in the connector 30 from escaping through the opening 31 during the sealing test of the product 70. By covering the opening 31 with the sealing part 43, it is not necessary to embed the sealing part 43 or the extrusion part 42 into the interior of the opening 31, which can reduce or even avoid damage to the connector 30 and the sealing ring in the opening 31 by the sealing component 40, and reduce the wear and tear on the structure of the product 70 during the testing process. Meanwhile, the area of the sealing part 43 is larger than the area of the opening 31. When the sealing part 43 covers the opening 31, the difficulty of covering can be reduced (this structural setting has low requirements for the position of the sealing part 43 and the opening 31. They do not need to be precisely aligned. It is only necessary that the sealing part 43 can cover the opening 31).
[0035] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7 In conjunction with the above embodiments, in some embodiments, the guide portion 41 has a connecting groove 411 at the end opposite to the pressing portion 42. The sealing member 40 includes a roller 44, which is at least partially located within the connecting groove 411 and is rotatably connected to the guide portion 41. The pushing portion 11 has an inclined surface 111 for pushing the roller 44 to move along a first direction X.
[0036] It is understandable that a connecting groove 411 can be formed on the side of the guide portion 41 away from the extrusion portion 42, so that the end of the guide portion 41 away from the extrusion portion 42 has a U-shaped structure. A roller 44 is set inside the connecting groove 411, which can reduce the space occupied by the roller 44. The roller 44 is connected to the inner wall of the connecting groove 411 through a rotating structure such as a rotating shaft, which allows the roller 44 to rotate. An inclined surface 111 is provided on the pushing portion 11. In the direction from the first support member 10 to the second support member 20, the horizontal distance from the side of the pushing portion 11 away from the inclined surface along the first direction X to the inclined surface 111 gradually decreases, and the inclined surface 111 is set when the first support member 10 and the second support member 20 are connected. When the pushing part 11 moves toward the second support member 20 along the second direction Y as the first support member 10 moves toward the second support member 20, it can squeeze the roller 44 through the inclined surface 111, so that the roller 44 drives the sealing member 40 to move toward the connector 30. As the first support member 10 moves toward the second support member 20, the inclined surface 111 can drive the roller 44 to rotate, thereby reducing the friction between the inclined surface 111 and the roller 44.
[0037] Please see Figure 1 , Figure 2 and Figure 11 In conjunction with the above embodiments, in some embodiments, the first support member 10 has a mounting hole 12 facing the second support member 20, a portion of the pushing part 11 is disposed in the mounting hole 12, at least a portion of the inclined surface 111 is located outside the mounting hole 12, and a reset part 13 is connected between the side of the pushing part 11 away from the second support member 20 and the bottom wall of the mounting hole 12.
[0038] Understandably, the first support member 10 has a mounting hole 12 facing the second support member 20. When the pushing part 11 pushes the roller 44, a portion of it can be embedded in the mounting hole 12, which can reduce the space occupied by the pushing part 11 to a certain extent and facilitate the connection between the first support member 10 and the second support member 20. At least a portion of the inclined surface 111 on the pushing part 11 is provided outside the mounting hole 12, facilitating the pushing of the roller 44 through the inclined surface 111. A reset part 13 is provided on the side of the pushing part 11 away from the second support member 20. The reset part 13 is connected to the inner wall of the mounting hole 12. After the first support member 10 and the second support member 20 are separated, the reset part 13 can reset the pushing part 11. The reset part 13 can be a structure with good elasticity, such as a spring or a spring sheet.
[0039] Please see Figure 5 and Figure 6In conjunction with the above embodiments, in some embodiments, the second carrier 20 has a connected fixing groove 23 and a sliding groove 24 on the side facing the first carrier 10, at least a portion of the product 70 is disposed in the fixing groove 23, and at least a portion of the sealing member 40 is disposed in the sliding groove 24.
[0040] It is understandable that a fixed groove 23 and a sliding groove 24, which are interconnected, can be provided on the side of the second support member 20 facing the first support member 10. The product 70 (including the connector 30 on the product 70) can be embedded in the fixed groove 23. The shape of the fixed groove 23 can be adapted to the shape of the product 70, which facilitates the partial embedding of the product 70, helps to limit the position of the product 70, improves its stability, and also reduces the space occupied by the product 70. A part of the sealing member 40 can be embedded in the interior of the sliding groove 24 and can slide along the first direction X inside the sliding groove 24. The sliding groove 24 can also play a certain guiding role in the sliding of the sealing member 40, and at the same time, it can reduce the space occupied by the sealing member 40.
[0041] Please see Figure 1 and Figure 2 In conjunction with the above embodiments, in some embodiments, the first carrier 10 has an installation cavity 14, and the sealing device includes a limiting member 50. The limiting member 50 is located in the installation cavity 14 and connected to the first carrier 10. The limiting member 50 is disposed on the side of the connector 30 away from the second carrier 20 and is used to squeeze and limit the connector 30.
[0042] It is understood that a mounting cavity 14 is provided on the side of the first carrier 10 facing the second carrier 20. A limiting member 50 can be provided inside the mounting cavity 14. The limiting member 50 can move along the second direction Y with the first carrier 10. When the first carrier 10 is connected to the second carrier 20, at least a portion of the limiting member 50 in the mounting cavity 14 can just abut against the upper surface of the connector 30 (the limiting member 50 can also abut against the upper surface of the entire product 70), preventing the connector 30 from moving along the second direction Y and improving its stability during the sealing process.
[0043] Please see Figure 1 In conjunction with the above embodiments, in some embodiments, the sealing device has a first state and a second state. In the first state, the first support member 10 and the second support member 20 are spaced apart. In the second state, the first support member 10 and the second support member 20 are connected and together form a receiving cavity 60, in which the product 70 and the sealing member 40 are both located. An air connection portion 15 is provided on one side of the first support member 10, and the air passage 151 of the air connection portion 15 communicates with the receiving cavity 60.
[0044] It is understandable that when sealing the connector 30, the first carrier 10 and the second carrier 20 can be connected, that is, both can be in a second state, and the two can enclose and form a receiving cavity 60, in which the product 70 and the sealing member 40 are both located. An air connection 15 is provided on the first carrier 10 or the second carrier 20, and the air passage 151 on the air connection 15 communicates with the receiving cavity 60. The air connector 15 can be connected to an external inflation device. After the opening 31 of the connector 30 is sealed by the sealing member 40, the inflation device injects gas into the receiving cavity 60 through the air passage 151 on the air connector 15. When the connector 30 is sealed and the product 70 is subjected to an airtightness test, an external airtightness testing instrument is connected to the product 70. If the airtightness testing instrument detects that the gas leakage value exceeds the set value within a specified time, the product 70 is unqualified for sealing. If the airtightness testing instrument detects that the gas leakage value is lower than the set value within a specified time, the product 70 is qualified for sealing.
[0045] A detection device includes the aforementioned sealing device. This detection device possesses all the technical features and beneficial effects of the sealing device, which will not be elaborated further here.
[0046] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0047] The sealing device and detection equipment provided in the embodiments of this application have been described in detail above, and specific examples have been used to illustrate the principle and implementation of this application. The description of the above embodiments is only for the purpose of helping to understand the technical solution and core idea of this application. Those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
