Technical Field
[0001] This utility model relates to the field of automotive wiring harness technology, specifically to a sealing mechanism for automotive air conditioning wiring harnesses. Background Technology
[0002] As the core network of automotive circuits, the importance of automotive wiring harnesses is self-evident; they are an indispensable part of constructing automotive circuits. The automotive air conditioning wiring harness, as a key branch, bears the heavy responsibility of power transmission and signal transmission in the automotive air conditioning system. Its performance directly affects the operational stability and reliability of the automotive air conditioning system and even the entire vehicle. When connecting automotive air conditioning wiring harnesses, a sealing structure needs to be installed at the connection point to improve safety. However, existing automotive air conditioning wiring harness sealing mechanisms still have certain shortcomings in use.
[0003] For example, the automotive air conditioning wiring harness sealing mechanism proposed in application number CN202121704921.8 includes a fixed base, a lower clamping plate provided on the upper outer surface of the fixed base, a sliding rod provided on the front outer surface of the fixed base, a movable block provided on the other outer surface of the sliding rod, and an upper clamping plate provided on the lower outer surface of the movable block. In actual use, when sealing two sets of wiring harness connectors at both ends of this sealing mechanism, the structural design of the movable block makes the clamping and sealing positions at both ends non-adjustable, thus making it impossible to adapt and adjust according to the spacing requirements of the automotive air conditioning wiring harness, reducing its practicality. At the same time, the sealing structure at both ends can only seal automotive air conditioning wiring harnesses of specific specifications and cannot be adapted to the size of the automotive air conditioning wiring harness, further reducing its practicality.
[0004] Therefore, we propose a sealing mechanism for automotive air conditioning wiring harnesses to address the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide a sealing mechanism for automotive air conditioning wiring harnesses, so as to solve the problems mentioned in the background art that it is inconvenient to adapt and adjust according to the wiring harness spacing requirements and inconvenient to adapt and seal according to the wiring harness specifications.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing mechanism for an automotive air conditioning wiring harness, comprising a right sealing shell and a left sealing shell;
[0007] A sealing gasket is fixedly installed at the connecting end of the upper right sealing shell and the lower right sealing shell, and the connecting end of the upper left sealing shell and the lower left sealing shell is fixedly connected to the sealing gasket.
[0008] A clamping and adjusting mechanism is connected between the right sealing shell and the left sealing shell for clamping and spacing adjustment;
[0009] An adjustable docking mechanism is installed at the front and rear ends of the right and left sealing shells to adapt to the sealing of automotive air conditioning wiring harnesses of different specifications.
[0010] Preferably, the clamping and adjusting mechanism includes a telescopic rod fixedly installed on the left side of the right sealing shell. A movable plate is also installed on the left side of the right sealing shell. Both the movable plate and the telescopic rod are provided in two sets. A limiting sleeve is sleeved on the outer ring of the movable plate. A positioning groove is opened at equal intervals in the middle of the movable plate. A positioning bolt is threaded through the top right end of the limiting sleeve. The positioning bolt is engaged with the positioning groove.
[0011] With the above-mentioned structural design, by loosening the positioning bolts, the movable plate can slide along the limit sleeve. Utilizing the telescopic characteristics of the telescopic rod, the distance between the right and left sealing shells can be flexibly adjusted to adapt to different wire harness spacing requirements. After adjusting to the appropriate position, tightening the positioning bolts will cause it to engage with the positioning groove, thus achieving stable positioning and ensuring that the sealing mechanism can reliably clamp the wire harness at different spacings.
[0012] Preferably, the clamping adjustment mechanism further includes an upper connecting plate fixedly connected to the bottom surface of the upper telescopic rod and the limiting sleeve, and a lower connecting plate fixedly connected to the top surface of the lower telescopic rod and the limiting sleeve. An adjusting screw is threaded through the middle of the upper connecting plate and the lower connecting plate, and a retaining ring is fixedly installed in the middle of the adjusting screw. The threads at both ends of the adjusting screw are arranged in opposite directions.
[0013] With the above-mentioned structural design, when the adjusting screw is rotated, due to the reverse threads at both ends, the upper connecting plate and the lower connecting plate will move synchronously to the middle or both sides, driving the telescopic rod and the movable plate and other components to work together to achieve the clamping and sealing of the automotive air conditioning wiring harness connector by the upper and lower right sealing shells and left sealing shells, further improving the ease of operation of the sealing and clamping work.
[0014] Preferably, the clamping adjustment mechanism further includes a limiting rod that slides through the rear end of the upper connecting plate and the front end of the lower connecting plate. The top end of the front limiting rod is fixedly connected to the bottom surface of the front end of the upper connecting plate, and the bottom end of the rear limiting rod is fixedly connected to the top surface of the rear end of the lower connecting plate.
[0015] With the above-mentioned structural design, the limiting rod can limit and guide the upper and lower connecting plates during the adjustment process, preventing them from shifting or tilting during movement, ensuring that the right sealing shell and the left sealing shell are adjusted in parallel, and improving the overall structural stability of the sealing mechanism.
[0016] Preferably, the adjustable docking mechanism includes mounting seats fixedly installed at the front and rear ends of the right and left sealing shells, a sealing ring is movably fitted inside the mounting seat, a rubber buckle is fixedly installed on the outer ring of the sealing ring, and a slot is opened inside the mounting seat.
[0017] Preferably, both the mounting base and the sealing ring are arranged in a semi-circular structure, the rubber buckles are distributed at equal angles on the outer ring of the sealing ring, and the sealing ring is connected to the groove by the rubber buckles.
[0018] With the above-mentioned structural design, sealing rings with different inner diameters can be flexibly selected according to different specifications of automotive air conditioning wiring harnesses. The sealing ring is quickly installed in the mounting base by the engagement of the rubber clip and the slot. The semi-circular structure of the mounting base and sealing ring makes the installation of the wiring harness convenient and can fit tightly to the surface of the wiring harness, effectively improving the sealing effect and achieving adaptable sealing for wiring harnesses of different specifications.
[0019] Compared with the prior art, the beneficial effects of this utility model are: the sealing mechanism for automotive air conditioning wiring harness;
[0020] 1. In solving the problem of wire harness spacing adaptation and adjustment, the unique clamping and adjustment mechanism design shows significant advantages. The cooperation of the telescopic rod, movable plate, limit sleeve and positioning bolt allows the spacing between the right and left sealing shells to be flexibly adjusted to meet the requirements of different wire harness spacings. The reverse thread linkage structure of the adjustment screw and the upper and lower connecting plates realizes the convenient switching between the clamping and separation states of the right and left sealing shells. The limit rod ensures that the adjustment process is stable and without deviation. The three work together to not only solve the problem that traditional sealing mechanisms are difficult to adapt to different wire harness spacings, but also greatly improve the convenience and stability of the sealing clamping operation.
[0021] 2. Addressing the sealing issue related to wire harness specification compatibility, the adjustable docking mechanism plays a crucial role. Through the rubber clips and slots of sealing rings with different inner diameters and mounting bases, it is possible to quickly replace and adapt to different specifications of automotive air conditioning wire harnesses. The semi-circular mounting base and sealing ring design not only facilitates wire harness installation but also ensures a tight fit to the wire harness surface, significantly improving the sealing effect. This design effectively solves the shortcomings of existing sealing mechanisms that cannot flexibly adapt to different wire harness specifications, providing reliable sealing protection for various automotive air conditioning wire harnesses and enhancing the versatility and practicality of the sealing mechanism.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-5 This utility model provides a technical solution: a sealing mechanism for automotive air conditioning wiring harnesses, including a right sealing shell 1 and a left sealing shell 2. A sealing gasket 3 is fixedly installed at the connecting end of the upper right sealing shell 1 and the lower right sealing shell 1. The connecting end of the upper left sealing shell 2 and the lower left sealing shell 2 is fixedly connected to the sealing gasket 3. A clamping and adjusting mechanism is connected between the right sealing shell 1 and the left sealing shell 2 for clamping and spacing adjustment. The clamping and adjusting mechanism includes a telescopic rod 4 fixedly installed on the left side of the right sealing shell 1. A movable plate 5 is also installed on the left side of the right sealing shell 1. Two sets of movable plates 5 and telescopic rods 4 are provided. A limiting sleeve 6 is sleeved on the outer ring of the movable plate 5. A positioning groove 7 is evenly spaced in the middle of the movable plate 5. The right end of the limiting sleeve 6 is threaded. A positioning bolt 8 is installed through the clamping mechanism and engages with the positioning groove 7. The clamping adjustment mechanism also includes an upper connecting plate 9 fixedly connected to the bottom surface of the upper telescopic rod 4 and the limiting sleeve 6, and a lower connecting plate 10 fixedly connected to the top surface of the lower telescopic rod 4 and the limiting sleeve 6. An adjusting screw 11 is threaded through the middle of the upper connecting plate 9 and the lower connecting plate 10. A retaining ring 12 is fixedly installed in the middle of the adjusting screw 11. The threads at both ends of the adjusting screw 11 are reversed. The clamping adjustment mechanism also includes a limiting rod 13 that slides through the rear end of the upper connecting plate 9 and the front end of the lower connecting plate 10. The top end of the front limiting rod 13 is fixedly connected to the bottom surface of the front end of the upper connecting plate 9, and the bottom end of the rear limiting rod 13 is fixedly connected to the top surface of the rear end of the lower connecting plate 10.
[0030] In the above structure design, when it is necessary to adjust the distance between the right sealing shell 1 and the left sealing shell 2, first loosen the positioning bolt 8 so that it is disengaged from the positioning groove 7. At this time, the movable plate 5 can slide freely in the limiting sleeve 6. At the same time, the telescopic rod 4 extends or retracts due to its own telescopic characteristics, thereby driving the left sealing shell 2 to move laterally relative to the right sealing shell 1 to achieve the adjustment of the distance. After the distance is adjusted to the position suitable for the installation of the wire harness, tighten the positioning bolt 8 so that it is inserted into the corresponding positioning groove 7. The relative position of the movable plate 5 and the limiting sleeve 6 is fixed by the thread locking force to complete the positioning.
[0031] When clamping and sealing the wire harness, place the connector of the wire harness inside the right sealing shell 1 and the left sealing shell 2 on both sides. Then rotate the adjusting screw 11. Due to the reverse thread design at both ends, the upper connecting plate 9 and the lower connecting plate 10 will move synchronously towards the middle or both ends along the adjusting screw 11. This action is fixedly connected to the telescopic rod 4 and the limiting sleeve 6 by the upper connecting plate 9 and the lower connecting plate 10, which drives the two sets of telescopic rods 4 and the movable plate 5 to move, and drives the upper and lower parts of the right sealing shell 1 to fit together to clamp and seal the right side of the wire harness. At the same time, the movement of the upper connecting plate 9 and the lower connecting plate 10 will also drive the upper and lower parts of the left sealing shell 2 to fit together to clamp and seal the left side of the wire harness. When disassembling, simply reverse the operation of the adjusting screw 11 to separate the upper and lower parts of the right sealing shell 1 and the left sealing shell 2, and the disassembly work can be achieved.
[0032] The retaining ring 12 in the middle of the adjusting screw 11 can limit the movement of the upper connecting plate 9 and the lower connecting plate 10. During this process, the limiting rod 13 provides guidance for the movement of the upper connecting plate 9 and the lower connecting plate 10 through sliding engagement, preventing them from shifting or tilting during the adjustment process, ensuring that the right sealing shell 1 and the left sealing shell 2 always remain parallel, and finally achieving tight clamping and sealing of wire harnesses with different spacing through the elastic deformation of the sealing gasket 3.
[0033] An adjustable docking mechanism is installed at the front and rear ends of the right sealing shell 1 and the left sealing shell 2 to adapt to the sealing of different specifications of automotive air conditioning wiring harnesses. The adjustable docking mechanism includes a mounting base 14 fixedly installed at the front and rear ends of the right sealing shell 1 and the left sealing shell 2. A sealing ring 15 is movably fitted inside the mounting base 14. Both the mounting base 14 and the sealing ring 15 are arranged in a semi-circular structure. A rubber buckle 16 is fixedly installed on the outer ring of the sealing ring 15. The rubber buckles 16 are evenly distributed on the outer ring of the sealing ring 15. A slot 17 is opened inside the mounting base 14. The sealing ring 15 is connected to the slot 17 by the rubber buckle 16.
[0034] When dealing with wire harnesses of different specifications, the above structure first selects a matching sealing ring 15 based on the diameter of the wire harness. Since both the mounting base 14 and the sealing ring 15 adopt a semi-circular structure design, the sealing ring 15 can be easily placed at the opening of the mounting base 14 during installation. Then, the rubber clips 16 distributed at equal angles on the outer ring of the sealing ring 15 are aligned with the slots 17 inside the mounting base 14. By pressing appropriately, the rubber clips 16 are inserted into the slots 17. The rubber clips 16 have a certain elastic deformation capability and can be tightly embedded in the slots 17 during the locking process, thereby firmly installing the sealing ring 15 in the mounting base 14.
[0035] When the right sealing shell 1 and the left sealing shell 2 clamp the automotive air conditioning wiring harness, the semi-annular mounting base 14 and the sealing ring 15 form a complete annular structure around the wiring harness. The sealing ring 15 can fit tightly against the surface of the wiring harness and fill the gap between the wiring harness and the sealing shell. Even if the wiring harness specifications are different, the sealing rings 15 with different inner diameters can ensure tight contact with the outer surface of the wiring harness. By utilizing the sealing properties of the rubber material, it effectively prevents external impurities such as dust and moisture from entering the wiring harness, thereby achieving reliable sealing for automotive air conditioning wiring harnesses of different specifications.
[0036] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
