[0058] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0060] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0061] To address the problem in existing sealing mechanisms where the conformal sealing head cannot be adjusted in position, preventing its insertion into the charger, this invention provides a sealing mechanism for airtightness testing of automotive chargers.

[0062] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0063] like Figures 1-7 As shown, the present invention provides a sealing mechanism for airtightness testing of car chargers, comprising:

[0064] XY floating unit 1, the XY floating unit includes a first mounting base 11 and a second mounting base 12, the first mounting base 11 and the second mounting base 12 are slidably connected by at least one first sliding member 13 so that the second mounting base 12 can slide relative to the first mounting base 11 in a first direction, and two first limiting plates 15 are provided at both ends of each first sliding member 13 to limit the position of the second mounting base 12 in the first direction, and at least one second sliding member 14 is provided on the side of the second mounting base 12 facing away from the first mounting base;

[0065] The sealing unit 2 includes a contoured sealing head 21 and a connecting seat 23. The contoured sealing head 21 is disposed on the connecting seat 23. The connecting seat 23 is slidably connected to the second mounting seat 12 via a second sliding member 14, so that the connecting seat 23 can slide relative to the second mounting seat in a second direction perpendicular to the first direction. Two second limiting plates 16 are provided at both ends of each second sliding member 14 to limit the position of the connecting seat 23 in the second direction.

[0066] It should be noted that the first direction is Figure 1 The direction represented by the X-axis can be denoted as the first direction X, and the direction represented by the Y-axis can be denoted as the second direction Y.

[0067] Understandably, refer to Figure 3 As shown, the blocking unit 2 can be finely adjusted in the second direction Y under the constraint of the two second limiting plates 16; while the reference Figure 2 As shown, the second mounting base 12 can be finely adjusted in the first direction X under the restriction of the two first limiting plates 15. When the contoured sealing head 21 is pressed into the car charger for air tightness testing, the contoured sealing head can float in the X and Y directions, which can ensure that the contoured sealing head is inserted into the sealing position of the connector.

[0068] refer to Figures 3-4 As shown, the specific structure of the first sliding member 13 includes two parallel first crossed roller guides 131 and a cooperating first roller 132. One first crossed roller guide 131 is fixed to the surface of the first mounting base 11, while the other is correspondingly mounted on the surface of the second mounting base 12 facing the first mounting base 11. The first roller 132 is cleverly fitted between the two first crossed roller guides 131, forming a stable sliding connection, allowing the second mounting base 12 to move smoothly relative to the first mounting base 11 along the first direction X.

[0069] In order to ensure the stability and safety of sliding, two first limit plates 15 are firmly installed outside the two ends of the two first cross roller guides 131, which serve as physical barriers and effectively limit the excessive movement of the second mounting base 12 in the first direction X, ensuring the flexibility of adjustment and the stability of the structure.

[0070] Further, referring to Figures 6-7 It is shown that the second sliding member 14 also adopts the combination design of cross roller guide and roller. Specifically, it includes two second cross roller guides 141 and second rollers 142 adapted thereto. One of the second cross roller guides 141 is fixedly installed on the surface of the second mounting base 12 facing away from the first mounting base 11, and the other is arranged at the corresponding position of the blocking unit 2, ensuring that the two can be accurately connected.

[0071] The second roller 142 is tightly embedded between the two second cross roller guides 141, realizing smooth sliding of the blocking unit 2 relative to the second mounting base 12 in the second direction Y. In order to control the sliding range and enhance the structural stability, two second limit plates 16 are respectively fixed outside the two ends of the two second cross roller guides 141, which serve as stop devices and effectively prevent the blocking unit 2 from moving beyond the expected movement in the second direction Y, ensuring the accuracy of adjustment and the reliability of the overall structure.

[0072] Referring to Figure 3 , Figure 5 It is shown that the XY floating unit 1 further integrates the design of the spring plunger 17, which is arranged in the second limit plate 16, and the positioning head 171 thereof plays a key role in abutting cooperation with the connecting seat 23, for accurately adjusting the position of the connecting seat 23 in the second direction Y. This design not only enhances the position adjustability of the blocking unit 2, but also ensures the convenience and accuracy of adjustment.

[0073] After the blocking unit 2 is finely adjusted in the X-axis and Y-axis and accurately inserted into the blocking position of the connector, when it needs to be removed from the blocking position, the positioning head 171 of the spring plunger 17 guides the connecting seat 23 to automatically return to the initial position (central position) in the second direction Y, thereby ensuring the resetting accuracy and stability of the blocking mechanism.

[0074] Further, referring to Figure 6 In order to comprehensively improve the adaptability and resetting ability of the blocking mechanism, the utility model can also optionally arrange the same spring plunger 17 on the first limit plate 15. In this way, when the blocking unit 2 is removed from the blocking position, the positioning head of the elastic plunger can guide the second mounting base 12 to quickly and accurately return to the initial position (central position) in the first direction X, further ensuring the reliability and practicality of the blocking mechanism.

[0075] Further, the sealing unit 2 is also carefully designed with a sealing ring 22, which is tightly fitted on the side wall of the profiled sealing head 21 and located close to the end of the profiled sealing head 21 away from the connecting seat 23. This design aims to enhance the sealing performance between the profiled sealing head 21 and the charger connector, effectively preventing gas leakage and ensuring the accuracy of the air tightness test. The material and size of the sealing ring 22 can be selected according to actual needs to adapt to different models and specifications of charger connectors, demonstrating the universality and practicality of the sealing unit 2.

[0076] Further reference Figure 5 As shown, the sealing mechanism also ingeniously incorporates a rack structure 4 as its stable support and driving core. The rack structure 4 is mainly composed of a rack body 41 and a driving unit 42 installed on it. The driving unit 42, as the power source, is carefully configured at a suitable position of the rack body 41, with its driving end closely connected to the first mounting seat 11. This design enables the first mounting seat 11 to achieve flexible and stable reciprocating motion in the third direction Z.

[0077] It is worth noting that this third direction Z is perpendicular to the previously described first direction X and second direction Y, forming a complete three-dimensional adjustment system. Reference Figure 1 In the intuitive display in , we can clearly see that the Z-axis represents this critical third direction. Such a design not only greatly enriches the adjustment dimensions of the sealing mechanism, but also provides strong support for the precise docking of the profiled sealing head 21 and the car charger, ensuring the accuracy and reliability of the air tightness test.

[0078] Reference Figure 1 and Figure 5 The design of the sealing mechanism also includes a bottom plate 5 and a linear guide rail 6 matched with it, providing stable guidance and support for the rack structure 4.

[0079] Specifically, the linear guide rail 6 is precisely installed on the upper surface of the bottom plate 5, and its extension direction is consistent with the second direction Y. The rack body 41 is slidingly arranged on the linear guide rail 6, achieving smooth sliding on the linear guide rail 6. Such a design not only enhances the overall stability of the sealing mechanism, but also provides precise guidance for its movement in the Y direction, further improving the convenience of the sealing mechanism operation.

[0080] In order to further improve the accuracy and automation level of adjustment, reference Figure 3As shown, the XY floating unit 1 also particularly includes a first magnetic sensor 18. This sensor is ingeniously mounted on the rack body 41, and its main function is to monitor and accurately measure the movement distance of the second mounting seat 12 in the third direction Z in real time. Through the accurate feedback of the first magnetic sensor 18, the operator can quickly understand the current position state, so as to realize the accurate adjustment of the position of the second mounting seat 12. Such a design not only improves the overall performance of the plugging mechanism, but also provides a strong guarantee for the accurate control of the air tightness detection process.

[0081] Further, the plugging mechanism is also equipped with a driving member 7 as the power source for the sliding of the rack body 41 on the linear guide rail 6. The driving member 7 is closely connected with the rack body 41 through a precise transmission mechanism, which ensures that after receiving the control signal, the rack body 41 can be quickly and smoothly driven to slide along the linear guide rail 6. Such a design not only enhances the flexibility of the plugging mechanism, but also makes the entire adjustment process more automated and accurate, providing a solid support for the efficient air tightness detection. At the same time, the selection of the driving member 7 also fully considers the durability and stability, ensuring the long-term reliable operation of the plugging mechanism.

[0082] In order to further improve the adjustment accuracy of the rack body 41 in the second displacement direction (i.e. the Y direction), with reference to Figure 5 As shown, a magnetic sensor 8 is particularly added. The sensor is carefully mounted on the driving member 7 and is closely connected with the sliding mechanism of the rack body 41. By monitoring the sliding distance of the rack body 41 on the linear guide rail 6 in real time, the magnetic sensor 8 can accurately feedback the current position information, providing accurate adjustment basis for the operator. This design not only enhances the intelligent level of the plugging mechanism, but also ensures the accurate and error-free position adjustment of the rack body 41 during the air tightness detection process.

[0083] In summary, the embodiments of the present application achieve the following technical effects:

[0084] The plugging unit 2 can be finely adjusted in the second direction Y under the limitation of the two second limiting plates 16, and the second mounting seat 12 can be finely adjusted in the first direction X under the limitation of the two first limiting plates 15. When the profiling plugging head 21 is pressed to the automobile charger for air tightness detection, the profiling plugging head can float in the X and Y directions, which can ensure that the profiling plugging head is inserted into the plugging position of the connector.
