Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to a sealing structure of an ECU connector. Background Art

[0002] With the development of automobile electrification, more and more structural parts in automobiles are driven by motors to meet the electric adjustment of corresponding structures. For example, the electric lifting of automobile windows uses a window motor as the power source, and the window is raised and stopped through the forward and reverse rotation and start and stop control of the window motor to meet the usage requirements.

[0003] In addition, in order to realize the modular production of automobiles and improve production efficiency, the electric structure thereon is usually equipped with an ECU connector to connect with the controller to ensure that the electrical connection is fast, convenient and stable. In addition, in order for the electric structure to operate safely and effectively, the ECU connector itself needs to be sealed to ensure that the electronic components and other structures inside it are not exposed to the air. At present, the existing ECU connectors on the market usually include a bottom shell, a cover plate and a corresponding circuit board structure. The bottom shell has an installation cavity, and the installation cavity has an opening. The corresponding circuit board structure is installed in the installation cavity from the opening. In addition, the cover plate is installed at the opening of the bottom shell, and a plug interface is provided on the cover plate for subsequent wiring. In addition, a sealing strip is provided between the cover plate and the bottom shell, and the sealing strip is used to achieve the sealing between the bottom shell and the cover plate to ensure the sealing of the ECU connector. Although the above structure can also achieve sealing, the sealing strip used is usually arranged in a horizontal state with the opening wall of the opening, that is, the sealing strip is arranged perpendicular to the sealing surface, and the sealing is achieved by the sealing edge of the sealing strip tightly against the cover. However, in the case of a plug-in sealing structure, the arrangement direction of the sealing strip is consistent with its plug-in direction, resulting in that when the sealing strip contacts the sealing surface and continues to be inserted and extruded, the processing accuracy of the sealing strip itself, the direction of force at the moment of contact with the sealing surface, and friction and other factors can easily cause different parts of the sealing strip to be compressed in different directions, so that gaps will be formed at the intersection of the sealing strips compressed in different directions, affecting the sealing performance. There is still a possibility of water leakage, and the reliability is poor. Summary of the invention

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To Attachment Figure 5 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0019] Figure 1 A structural diagram of an embodiment of a sealing structure of an ECU connector of the present invention; Figure 2 A structural diagram of a gear box of a sealing structure of an ECU connector of the present invention; Figure 3 FIG. 1 is a structural diagram of a connector seat of a sealing structure of an ECU connector of the present invention. Figure 1 , Figure 2 as well as Figure 3 As shown, the sealing structure of the ECU connector provided in this embodiment includes a gear box 1 and a connector seat 2, which is used for sealing between the gear box 1 and the connector seat 2 to ensure the sealing performance of the ECU connector.

[0020] Specifically, the gearbox 1 and the connector seat 2 are both semi-open structures. At this time, the opening of the gearbox 1 is an L-shaped opening, that is, the two faces of the gearbox 1 are both open. At the same time, the connector seat 2 is arranged in an "L" shape. The installation of the connector seat 2 on the gearbox 1 forms a relatively sealed rectangular parallelepiped structure, which provides a sealed, safe and reliable installation space for the installation of structures such as control circuit boards. In addition, it is also convenient to realize the plug-in installation of the connector seat 2 on the gearbox 1, which meets the installation requirements of control circuit boards and other structures arranged in a plane. At this time, the gearbox 1 also includes a front vertical wall 11, two side vertical walls 12 and a bottom wall 13. From the overall point of view, the two side vertical walls 12 are respectively located on both sides of the front vertical wall 11, and the bottom wall 13 is arranged below the front vertical wall 11 and the two side vertical walls 12 and are all connected to each other, that is, forming four mutually interacting faces of a rectangular structure. At the same time, the connector seat 2 includes a top wall 21 and a rear vertical wall 22. From the overall point of view, the top wall 21 is arranged above the rear vertical wall 22 and connected, that is, an "L"-shaped structure is formed between the top wall 21 and the rear vertical wall 22, forming two mutually interacting surfaces of a rectangular structure. Moreover, when the connector seat 2 is installed on the gear box 1, the top wall 21 is located above the bottom wall 13 and is respectively connected to the front vertical wall 11 and the two side vertical walls 12, the rear vertical wall 22 is arranged at intervals from the front vertical wall 11 and is located between the two side vertical walls 12, and the rear vertical wall 22 is connected to the two side vertical walls 12 and the bottom wall 13, that is, the four mutually interacting surfaces of the gear box 1 and the two mutually interacting surfaces of the connector seat 2 form six surfaces of a complete rectangular structure, thereby meeting the use requirements of forming a sealing structure. At the same time, an L-shaped mounting block 3 is provided on the inner side of the connector seat 2, that is, after the connector seat 2 is installed on the gear box 1, the L-shaped mounting block 3 is located in the gear box 1, and one side of the L-shaped mounting block 3 is fixed to the top wall 21 and the rear vertical wall 22, so that the top wall 21 and the rear vertical wall 22 of the connector seat 2 have corresponding partial structures of the L-shaped mounting block 3, and at the same time, a first sealing surface 31 is formed on the outer side wall of the L-shaped mounting block 3, and a circle of sealing strip 4 is arranged on the first sealing surface 31, so that when the connector seat 2 is installed on the gear box 1, since the L-shaped mounting block 3 is located in the gear box 1, the sealing strip 4 located on the L-shaped mounting block 3 can directly abut against the inner wall of the gear box 1, that is, the sealing between the connector seat 2 and the gear box 1 is achieved by the sealing strip 4. In addition, the cross-section of the sealing portion 41 of the sealing strip 4 is arranged in a triangular shape, and the edge at a sharp corner facing away from the first sealing surface 31 is selected as the sealing edge 411. When sealing, the sealing edge 411 contacts the inner wall of the gear box 1 to achieve sealing, and as the depth of the connector seat 2 inserted into the gear box 1 increases, the sealing edge 411 is squeezed, thereby improving the effectiveness and reliability of the seal.In addition, the sealing edge 411 is arranged at an inclined angle to the first sealing surface 31, and the inclination direction of the sealing edge 411 is arranged toward the top wall 21 and the rear vertical wall 22, that is, the sealing edge 411 itself is preset with an inclination angle, so that when the connector seat 2 is plugged into the gear box 1, the sealing edge 411 can be bent toward the preset inclination angle during the extrusion process, thereby maintaining the consistency of the inclination of the sealing edge 411, avoiding the problem of gaps formed between different inclined parts due to the random inclination of the existing sealing edge 411, improving the effectiveness and reliability of the seal, and making the structural design more reasonable.

[0021] More specifically, the first sealing surface 31 of the L-shaped mounting block 3 and the three surfaces located on the corresponding top wall 21 correspond to the front vertical wall 11 and the two side vertical walls 12 of the gear box 1 respectively. At this time, the portion of the sealing strip 4 on the first sealing surface 31 corresponding to the two vertical side walls is arranged obliquely on the first sealing surface 31, so that in the direction along which the connector seat 2 is plugged into the gear box 1, the middle portion of the sealing strip 4 used to connect its horizontal section and vertical section is also arranged obliquely, thereby being arranged at an oblique angle with the plugging direction. Moreover, along the direction from the front vertical wall 11 to the rear vertical wall 22, the inclination direction of the sealing strip 4 is inclined from the top wall 21 to the bottom wall 13, so that when the connector seat 2 is plugged into the gear box 1, the friction force of the inner wall of the gear box 1 on the sealing edge 411 of the sealing strip 4 is an oblique upward force, which better complies with the structural requirement that the sealing edge 411 of the sealing strip 4 is inclined outward, so that the sealing edge 411 of the sealing strip 4 can be more smoothly inclined and bent in the same direction to ensure the sealing performance.

[0022] More specifically, a plurality of sealing portions 41 are arranged in parallel on the same sealing strip 4. At this time, the plurality of sealing portions 41 are arranged at intervals, and the arrangement direction of each sealing portion 41 is consistent with the arrangement direction of the sealing strip 4 where it is located, and the shapes of the plurality of sealing portions 41 are arranged the same, so that the sealing strip 4 and the inner wall of the gear box 1 are sealed by a plurality of sealing portions 41, and the sealing effect of each sealing portion 41 is the same, thereby further improving the sealing performance.

[0023] More specifically, a clamping foot 23 is provided on both sides of the rear vertical wall 22. At the same time, a clamping block 14 corresponding to the clamping foot 23 is provided on the outer walls of the vertical walls 12 on both sides. At this time, one clamping foot 23 corresponds to one clamping block 14, so that when the connector seat 2 is plugged into the gear box 1, the clamping foot 23 can cooperate with the corresponding clamping block 14 to realize the clamping connection between the connector seat 2 and the gear box 1, which is more convenient for disassembly and assembly.

[0024] More specifically, a first slide groove 15 is provided on the outer wall of each side vertical wall 12 and in a direction parallel to the top wall 21 or the bottom wall 13, and the clamping foot 23 is slidably connected to the first slide groove 15 on the corresponding side, that is, when the connector seat 2 is installed on the gear box 1, the connection can be achieved by sliding the clamping foot 23 in the first slide groove 15, which provides a guide for maintaining the installation direction during plug-in and clamping, and also provides conditions for maintaining the stability of the fit after subsequent installation.

[0025] More specifically, a second slide groove 16 is provided on the inner wall of each side vertical wall 12 and in a direction parallel to the top wall 21 or the bottom wall 13. At the same time, plug blocks 24 corresponding to the two second slide grooves 16 are respectively provided on both sides of the L-shaped mounting block 3. That is, when the connector seat 2 is plugged into the gear box 1, the installation guide can be realized by sliding the plug blocks 24 in the corresponding second slide grooves 16, so that the various parts can correspond accurately when they are matched, thereby improving the accuracy of the installation direction and facilitating disassembly and assembly.

[0026] More specifically, a plurality of upper clamping edges 111 extending toward the rear vertical wall 22 are also provided at the top of the front vertical wall 11. At the same time, the plurality of upper clamping edges 111 are arranged at intervals so that gaps can be left between the plurality of upper clamping edges 111. At the same time, a limiting edge is formed at the top of the front vertical wall 11 by the upper clamping edges 111, which provides conditions for subsequently limiting the upward movement of the top wall 21. In addition, a plurality of matching clamping edges 211 are also provided on the top wall 21. At this time, the plurality of matching clamping edges are arranged at intervals so that the matching clamping edges 211 can adapt to the arrangement requirements of the upper clamping edges 111. In addition, when the connector seat 2 is installed on the gear box 1, the plurality of upper clamping edges 111 and the plurality of matching clamping edges 211 are alternately engaged, so that there are a plurality of alternately arranged connection points between the gear box 1 and the connector seat 2, which improves the connection strength and ensures the installation accuracy. In addition, a first avoidance notch 112 corresponding to the mating edge 211 is provided on the front vertical wall 11, and at the same time, a second avoidance notch 212 corresponding to the upper edge 111 is provided on the top wall 21, so that when the connector seat 2 and the gear box 1 are matingly installed, the upper edge 111 can extend into the first avoidance notch 112 to limit the upward movement of the top wall 21 relative to the gear box 1. At the same time, the mating edge 211 extends into the second avoidance notch 212 to limit the downward movement of the top wall 21 relative to the gear box 1, so that the gear box 1 and the connector seat 2 can be stably positioned, thereby improving the connection stability between the two and meeting the use requirements of plugging and unplugging the connector thereon.

[0027] Figure 4 This is a structural diagram of a gearbox with a first arrangement protrusion, a second arrangement protrusion and a third arrangement structure according to a preferred embodiment of the present invention. Figures 1 to 4As shown, a first arranging protrusion 17 is provided on the upper part of the inner wall of each side vertical wall 12. At this time, the first arranging protrusion 17 is arranged on the side of the side vertical wall 12 close to the rear vertical wall 22, so that when the connector seat 2 is installed on the gear box 1, the sealing strip 4 can contact the first arranging protrusion 17 at the first time, which provides conditions for combing the compression direction of the sealing strip 4 through the first arranging protrusion 17 during the subsequent installation process. At the same time, when the sealing strip 4 installed on the first sealing surface 31 is installed, it is preset that the lowest point of the end of the sealing strip 4 near the front vertical wall 11 at the inclined position on the first sealing surface 31 is higher than the highest point at the end near the rear vertical wall 22, that is, the distance between the highest point of one end of the sealing strip 4 at the inclined position on the surface of the side wall corresponding to the first sealing surface 31 and the lowest point of the other end can be greater than the width of the sealing strip 4, so that when the sealing strip 4 is combed by the first arranging protrusion 17, as the insertion depth of the connector seat 2 on the gear box 1 gradually increases, the first arranging protrusion 17 can move from the bottom of the sealing strip 4 to the top of the sealing strip 4, thereby realizing the combing of the sealing strip 4. At the same time, during installation, when the connector seat 2 initially contacts the gear box 1, the first tidying protrusion 17 is located below the lowest point of the sealing strip 4 on the first sealing surface 31 where the slant is arranged, close to the front vertical wall 11 at one end. Moreover, when the connector seat 2 is installed in place on the gear box 1, the first tidying protrusion 17 is located above the highest point of the sealing strip 4 on the first sealing surface 31 where the slant is arranged, close to the rear vertical wall 22 at one end. During the installation process, the sealing edge 411 of the sealing strip 4 can be combed by the first tidying protrusion 17 so that the sealing edge 411 is bent and deformed toward the same side, thereby ensuring the sealing performance. In addition, the first tidying protrusion 17 after installation can be located on the outside of the sealing strip 4 without interfering with the sealing of the sealing strip 4, and the structural design is more reasonable.

[0028] More specifically, a second arranging protrusion 18 is also provided on the inner wall of the bottom wall 13 and on the side close to the rear vertical wall 22, and when the connector seat 2 is plugged into the side of the gear box 1, the sealing strip 4 on the side of the first sealing surface 31 corresponding to the bottom wall 13 can contact the second arranging protrusion 18 at the first time, and pass through the second arranging protrusion 18 as the insertion depth of the connector seat 2 increases, and the sealing edge 411 of the sealing strip 4 corresponding to the bottom wall 13 is combed by the second arranging protrusion 18, so that the sealing strip 4 corresponding to the bottom wall 13 can also be squeezed and bent toward the same side to ensure the sealing performance. In addition, when installed in place on the gear box 1, the second arranging protrusion 18 is located on the side of the sealing strip 4 close to the rear vertical wall 22, so that the sealing strip 4 after sealing is completed will no longer be affected by the second arranging protrusion 18, ensuring the sealing effect.

[0029] Figure 5 FIG. 2 is a cross-sectional view of a third finishing structure of a preferred embodiment of the present invention. Figures 1 to 5As shown, a third arranging structure 5 is also provided on the gearbox 1, and the sealing edge 411 of the sealing strip 4 relative to the front vertical wall 11 is combed by the third arranging structure 5 to ensure the sealing performance. At this time, the third arranging structure 5 also includes a slide 51, a U-shaped arranging frame 52, a third arranging protrusion 57, a trigger block 53, a spring 54 and a lifting spring 55. When installed, the slide 51 is arranged on the outer wall of the front vertical wall 11. Preferably, the slide 51 and the front vertical wall 11 are an integral injection molding structure, which improves the reliability of the connection of the slide 51. In addition, the opening of the U-shaped arranging frame 52 is arranged downward and one end is inserted into the slide 51. At the same time, the other end of the U-shaped arranging frame 52 is arranged close to the inner wall of the front vertical wall 11 and the end is provided with a third arranging protrusion 57, so that the third arranging protrusion 57 can move up and down in the gearbox 1 with the U-shaped arranging frame 52, which provides conditions for combing the sealing edge 411 of the sealing strip 4 by the third arranging protrusion 57 in the future. In addition, the slide 51 provides a slideway for the up and down movement of the U-shaped tidying frame 52 to maintain the stability of the U-shaped tidying frame 52 when it moves. In addition, the lifting spring 55 is installed in the slide 51 and the upper end is in contact with one end of the U-shaped tidying frame 52 inserted into the slide 51. The lifting spring 55 provides power for the upward movement of the U-shaped tidying frame 52, that is, when the sealing edge 411 of the sealing strip 4 is combed by the third combing protrusion 57 later, the lifting spring 55 can drive the third combing protrusion 57 to move relative to the sealing strip 4, thereby meeting the combing requirements. In addition, a trigger hole 511 is opened on the side wall of the slide 51. At the same time, the trigger block 53 is installed on one end of the U-shaped sorting frame 52 inserted into the slide 51 and is always located in the trigger hole 511 when the top wall 21 does not contact the U-shaped sorting frame 52. The U-shaped sorting frame 52 is temporarily positioned by the mutual engagement of the trigger block 53 and the trigger hole 511, and the movement of the U-shaped sorting frame 52 is restricted, so that when the connector seat 2 is not installed on the gear box 1, the end of the U-shaped sorting frame 52 with the third sorting protrusion 57 can be maintained in the gear box 1, providing conditions for subsequent upward movement.At the same time, an escape slide 512 is also provided in the inner cavity of the slide cylinder 51 and on the side away from the U-shaped arranging frame 52. The arrangement direction of the escape slide 512 is consistent with the upward movement direction of the U-shaped arranging frame 52. When the trigger block 53 escapes from the trigger hole 511, the end of the U-shaped arranging frame 52 inserted into the slide cylinder 51 moves into the escape slide 512. That is, when the connector seat 2 is installed on the gear box 1 and the top wall 21 approaches the front vertical wall 11, if the top wall 21 contacts and pushes the U-shaped arranging frame 52, The U-shaped arranging frame 52 moves toward the side of the avoidance slide 512, so that the trigger block 53 on the U-shaped arranging frame 52 escapes from the trigger hole 511, so that the U-shaped arranging frame 52 moves upward under the action of the jacking spring 55, thereby driving the third arranging protrusion 57 to move upward, so that the sealing edge 411 of the sealing strip 4 that just moves over at this time is combed upward by the third arranging protrusion 57, so that the sealing edge 411 of the sealing strip 4 can be squeezed in the same direction, thereby ensuring the sealing performance. At the same time, a spring sheet 54 is also provided on one end of the U-shaped arranging frame 52 inserted into the slide 51. At this time, one end of the spring sheet 54 is extended into the avoidance slide 512, that is, when the U-shaped arranging frame 52 does not move, the U-shaped arranging frame can be supported by the spring sheet 54, thereby maintaining the state of the trigger block 53 being stuck in the trigger hole 511. When the U-shaped arranging frame 52 is pushed by the top wall 21, the spring sheet 54 can be deformed to adapt to meet the use requirements of the trigger block 53 being disengaged from the trigger hole 511. In addition, a limiting pressure cover 56 is also provided at the upper tube mouth of the slide 51. At this time, the limiting pressure cover 56 is sleeved outside the end of the U-shaped arranging frame 52 inserted into the slide 51. The limiting pressure cover 56 can be used to limit the upper tube mouth of the slide 51 to prevent the U-shaped arranging frame 52 from accidentally disengaging from the slide 51. Preferably, the limiting gland 56 is connected to the outer wall of the slide 51 by a snap connection, which facilitates the disassembly and assembly of the limiting gland 56 and the U-shaped arrangement frame 52 and other structures on the slide 51. At the same time, when the top wall 21 does not contact the U-shaped arrangement frame 52, the third arrangement protrusion 57 is located below the sealing strip 4. After the top wall 21 contacts the U-shaped arrangement frame 52, the end of the U-shaped arrangement frame 52 with the third arrangement protrusion 57 moves up to the top of the sealing strip 4, which can not only ensure that the sealing edge 411 of the sealing strip 4 is combed, but also ensure that the sealing strip 4 is no longer affected by the third arrangement structure 5 after sealing, thereby ensuring the sealing effect.

[0030] The sealing structure of the ECU connector provided in this embodiment includes a gear box 1 and a connector seat 2; the gear box 1 and the connector seat 2 are set to a semi-open structure, and the connector seat 2 is plugged into the semi-open part of the gear box 1. At the same time, an L-shaped mounting block 3 with a circle of sealing strip 4 is provided on the connector seat 2, and the cross section of the sealing portion 41 of the sealing strip 4 is arranged in a triangular shape and the edge where the sharp corner of the inner wall of the gear box 1 is located is used to form a sealing edge 411. At the same time, the sealing edge 411 of the sealing strip 4 is tilted toward the outside of the connector seat 2, so that when the connector seat 2 is plugged into the gear box 1, the connector seat 2 and the gear box 1 move horizontally relative to each other, and the sealing edges 411 of the sealing strip 4 are preset with an inclined direction toward the outside of the connector seat 2, so that when the sealing edges 411 of the sealing strip 4 contact the inner wall of the gear box 1 and are compressed, the sealing edges 411 can be compressed and deformed in the same direction, thereby effectively avoiding the problem of poor sealing caused by different compression directions of the sealing edges 411, and having better sealing performance and higher safety in use.
