Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a liquid cooling heat dissipation interface connection mechanism for charging piles. Background Technology

[0002] The "liquid-cooled heat dissipation interface for charging piles" is not a single component, but an active heat dissipation system integrated into the charging gun and cable. Its core purpose is to solve the extreme heat generated during high-current charging, ensuring a safe and efficient charging process and improving the user experience.

[0003] However, in existing technologies, traditional pipeline connection equipment mostly relies on manual operation, which has high operational difficulty and error risk. Manual adjustment and positioning often take a long time and it is difficult to guarantee the accuracy of each operation, which can easily lead to poor pipeline sealing or weak connection. This is especially serious in high-pressure and high-temperature environments, causing safety hazards such as leakage. Secondly, the stability of pipeline connections in existing technologies is poor, especially under long-term use or high load conditions, when pipelines may loosen or fall off due to weak connections. In addition, many devices lack effective automatic positioning and pressure regulation functions, and deviations are prone to occur during the connection process, leading to a decline in the overall performance of the pipeline system, which in turn affects the operating efficiency and safety of the equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that traditional pipeline connection equipment in the prior art relies heavily on manual operation, which has high operational difficulty and error risk, and manual adjustment and positioning often takes a long time. Therefore, a liquid cooling heat dissipation interface connection mechanism for charging piles is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a charging pile liquid cooling heat dissipation interface connection mechanism, including a first connecting pipe and a second connecting pipe, a first outer ring is fixedly connected to the outer surface of the middle part of the first connecting pipe, and a connecting pipe is fixedly connected to one end of the first connecting pipe, a second outer ring is fixedly connected to the outer surface of one end of the second connecting pipe, and multiple locking blocks are fixedly connected to the outer surface of the connecting pipe and the outer surface of the second connecting pipe, and a locking mechanism is fixedly connected to the outer surface of the locking blocks. The locking mechanism includes a fixed plate fixedly installed on the side wall of the locking block. A limit block is fixedly connected to one side of the fixed plate. A threaded rod is threaded to one end of the fixed plate. A movable frame is rotatably connected to one end of the threaded rod. A movable block is rotatably connected to the inner side of the movable frame. A limit groove is opened on the outer surface of the limit block. The side wall of the movable block is slidably connected to the limit groove. A pressing block is fixedly connected to one end of the movable block.

[0006] Preferably, one end of the connecting pipe is fixedly connected to the first track, and one end of the second connecting pipe is fixedly connected to the second track.

[0007] Preferably, the first track is slidably connected to the locking block on the surface of the second connecting tube.

[0008] Preferably, the second track is slidably connected to the locking block on the surface of the connecting pipe.

[0009] Preferably, an inner tube is installed inside the second connecting tube, and a sealing ring is fixedly connected to the outer surface of one end of the inner tube.

[0010] Preferably, the inner cavity of one end of the second connecting pipe is provided with a threaded groove, and the outer surface of one end of the first connecting pipe is provided with a threaded groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the connection between the locking block, the track and the pipe ensures the stable splicing between the pipes. Then, the rotating threaded rod drives the moving frame to move along the predetermined track, causing the movable block to slide in the limiting groove. The rotational connection between the movable block and the extrusion block causes the extrusion block to rotate and gradually approach the first outer ring along the horizontal trajectory to complete the extrusion positioning. In addition, the locking mechanism contacts the side wall of the second outer ring during the positioning process and achieves precise fixation by applying uniform pressure. The whole process ensures the stability and sealing of the pipeline system during connection and positioning. 2. In this utility model, when connecting the connecting pipe and the second connecting pipe, the second connecting pipe is rotated so that its surface locking block aligns with the first track, thereby achieving a tight fit between the connecting pipe and the second connecting pipe. At the same time, the locking block and the second track engage with each other to ensure a stable connection. The mating fit between the inner pipe and the inner cavity of the connecting pipe effectively ensures smooth fluid flow. The sealing ring improves the sealing performance and prevents leakage. The matching design of the external thread of the first connecting pipe and the internal thread of the second connecting pipe makes connection and disassembly more convenient, ensuring the flexibility and maintainability of the system.

Detailed Implementation

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figures 1-3 As shown, this utility model provides a charging pile liquid cooling heat dissipation interface connection mechanism, including a first connecting pipe 1 and a second connecting pipe 3. A first outer ring 12 is fixedly connected to the outer surface of the middle part of the first connecting pipe 1, and a connecting pipe 11 is fixedly connected to one end of the first connecting pipe 1. A second outer ring 31 is fixedly connected to the outer surface of one end of the second connecting pipe 3. Multiple locking blocks 4 are fixedly connected to the outer surface of the connecting pipe 11 and the outer surface of the second connecting pipe 3. A locking mechanism 2 is fixedly connected to the outer surface of the locking block 4. The locking mechanism 2 includes a fixed plate 21 fixedly installed on the side wall of the locking block 4. A limit block 22 is fixedly connected to one side of the fixed plate 21. A threaded rod 27 is threadedly connected to one end of the fixed plate 21. A movable frame 26 is rotatably connected to one end of the threaded rod 27. A movable block 24 is rotatably connected to the inner side of the movable frame 26. A limit groove 23 is opened on the outer surface of the limit block 22. The side wall of the movable block 24 is slidably connected to the limit groove 23. A pressing block 25 is fixedly connected to one end of the movable block 24.

[0017] The specific settings and functions of this embodiment will be described in detail below. In the operation of this device, firstly, by precisely locking the connection between the block 4, the first track 13 and the second track 32, the stable splicing of the connecting pipe 11 and the second connecting pipe 3 can be achieved.

[0018] Next, when the threaded rod 27 is rotated, it interacts with the connecting piece through its embedded threaded structure, thereby initiating the movement of the movable frame 26 along the predetermined track. During this process, the displacement of the movable frame 26 is not only controlled by the rotation of the threaded rod 27, but also closely cooperates with its internal transmission mechanism, ensuring that the movable frame 26 can precisely translate along the set path.

[0019] As the movable frame 26 moves, the movable block 24 also moves accordingly. Since the movable block 24 is connected to the movable frame 26 via a rotatable connection, the horizontal movement of the movable frame 26 causes the movable block 24 to slide precisely within the limiting groove 23. The design of the limiting groove 23 plays a crucial role; it not only restricts the free movement of the movable block 24 in the vertical direction but also ensures smooth movement and positioning of the block through friction with the movable block 24.

[0020] Since the movable block 24 and the moving frame 26 are rotatably connected, the movable block 24 not only slides along a horizontal trajectory during movement, but also drives the pressing block 25 to rotate through the part connected to the pressing block 25. Specifically, when the movable block 24 slides along the limiting groove 23, the pressing block 25 will rotate 90 degrees, and this rotation will ensure that the pressing block 25 always moves synchronously with the movable block 24.

[0021] During this process, the extrusion block 25 gradually approaches the first outer ring 12 and eventually achieves extrusion positioning. At this point, the extrusion block 25 is firmly fixed on the first outer ring 12, completing the final positioning operation, thereby ensuring the correct position and stability of the pipeline system in the overall structure.

[0022] In addition, the locking mechanism 2 on the outer surface of the connecting pipe 11 plays a crucial role in the final stage of the positioning operation. When the locking mechanism 2 is working, the extrusion block 25 will make close contact with the side wall of the second outer ring 31, and the pipe will be precisely extruded and positioned by uniformly applying pressure to the side wall of the second outer ring 31.

[0023] Example 2: Figure 2 and Figure 4 As shown, a first track 13 is fixedly connected to one end of the connecting pipe 11, and a second track 32 is fixedly connected to one end of the second connecting pipe 3. The first track 13 is slidably connected to a locking block 4 on the surface of the second connecting pipe 3. The second track 32 is slidably connected to a locking block 4 on the surface of the connecting pipe 11. An inner tube 33 is installed inside the second connecting pipe 3, and a sealing ring 34 is fixedly connected to the outer surface of one end of the inner tube 33. A threaded groove is provided in the inner cavity of one end of the second connecting pipe 3, and a threaded groove is provided on the outer surface of one end of the first connecting pipe 1.

[0024] The overall effect of this embodiment is that, during the connection of the connecting pipe 11 and the second connecting pipe 3, the entire process ensures a strong and airtight connection through a series of precise mechanical adjustments. First, when the connecting pipe 11 and the second connecting pipe 3 are joined, the user can initiate the connection operation by rotating the second connecting pipe 3. As the second connecting pipe 3 rotates, the locking block 4 on its surface gradually engages with the first track 13. At this time, due to the restriction of rotation by the first track 13, the second connecting pipe 3 is gradually guided, thereby creating a tight fit between the connecting pipe 11 and the second connecting pipe 3.

[0025] During this process, another locking block 4 on the surface of the connecting pipe 11 also engages with the second track 32, further enhancing the stability and firmness of the connection. The design of the second track 32 serves to guide and restrict, ensuring precise alignment between the connecting pipe 11 and the second connecting pipe 3 during the connection process, preventing loosening or poor contact due to errors. Furthermore, the engagement of the locking block 4 and the track is not merely a physical connection process; it also prevents the joint from loosening, ensuring the stability of the joint during long-term use.

[0026] While connecting the pipes, the alignment of the inner pipe 33 with the inner cavity of the connecting pipe 11 is also crucial. The alignment of the inner pipe 33 ensures smooth fluid flow, and the presence of the sealing ring 34 is one of the key factors for a successful connection. Located at the connection interface, the sealing ring 34, through its elasticity and material properties, effectively fills tiny gaps, forming a good seal. This sealing structure significantly reduces the risk of fluid leakage due to loose connections, thereby improving the safety and reliability of the system.

[0027] Furthermore, the mating design of the external thread of the first connecting pipe 1 and the internal thread of the second connecting pipe 3 makes connection and disassembly operations simpler and more efficient. Through the engagement of the threads, a quick and secure connection can be achieved without the use of additional tools, and disassembly or maintenance can be easily performed when necessary, ensuring the flexibility and maintainability of the piping system.

[0028] The usage and working principle of this device are as follows: When splicing the connecting pipe 11 and the second connecting pipe 3, the locking block 4 is first inserted into the first track 13 and the second track 32 respectively to align and connect them. Then, the threaded rod 27 is rotated to drive the moving frame 26 to move horizontally. The moving frame 26 is rotatably connected to the movable block 24, which moves within the limiting groove 23. Under the constraint of the limiting groove 23, the movable block 24 not only moves horizontally but also drives the extrusion block 25 to rotate 90 degrees. As the moving frame 26 continues to advance, the extrusion block 25 gradually approaches the first outer ring 12 and finally completes the extrusion positioning.

[0029] Meanwhile, when the locking mechanism 2 located on the outer surface of the connecting pipe 11 performs positioning, its squeezing block 25 will also squeeze the side wall of the second outer ring 31 to enhance the positioning effect.

[0030] During the docking process between the connecting pipe 11 and the second connecting pipe 3, rotating the second connecting pipe 3 allows the locking block 4 on its surface to slide along the first track 13. As the rotation progresses, the locking block 4 gradually engages with the second track 32, thereby ensuring a tight fit between the two pipes. During this process, the inner pipe 33 is inserted into the inner cavity of the connecting pipe 11, and the sealing ring 34 provides a seal, effectively preventing leakage.

[0031] In addition, the external thread of the first connecting pipe 1 mates with the internal thread of the second connecting pipe 3, which further facilitates installation and disassembly.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
