Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a refrigeration hard pipe for new energy vehicles. Background Art

[0002] The air conditioning pipeline is a component that connects the compressor, condenser and evaporator in the refrigeration circuit. It plays an important role in transmitting refrigerant, thereby regulating the temperature inside the car and providing sufficient comfort for passengers.

[0003] The inventor of this application found that there are the following problems in the practical use process:

[0004] At present, the refrigeration rigid pipes of new energy vehicles will install the connectors to the frame through nuts. During the installation of the connectors, it is necessary to hold the nut and align it with the bolt, and then tighten the nut and bolt. During this process, the nut may fall off, which will affect the efficiency of assembly.

[0005] Therefore, it is necessary to provide a new energy vehicle refrigeration hard pipe to solve the above technical problems. Utility Model Content

[0006] The technical problem to be solved by the utility model is that during the installation process, nuts may fall off, thereby affecting the assembly efficiency. In view of the above-mentioned defects of the prior art, a new energy vehicle refrigeration hard pipe is provided.

[0007] To achieve the above-mentioned purpose, the technical solution of the utility model is: a new energy vehicle refrigeration rigid pipe, including a connecting head, one side of the connecting head is fixedly connected to a vertical plate, the vertical plate is provided with a through hole, the front side of the through hole is fixedly connected to a pad, the pad is provided with a groove, the groove is rotatably connected to a receiving mechanism, the receiving mechanism includes a rotating ring, and one side of the rotating ring is fixedly connected to a receiving groove.

[0008] By adopting the above technical solution, the connector enables the refrigeration hard pipe to be conveniently connected to the vehicle frame, while the vertical plate and the through holes thereon provide a fixing basis, so that the whole can be screwed to the vehicle body using the through holes.

[0009] It is further provided that triangular grooves are provided around the cushion block, and a plurality of the triangular grooves are provided, and the plurality of triangular grooves are evenly arranged in a ring shape along the central axis of the rotating ring.

[0010] By adopting the above technical solution, the multiple triangular grooves opened around the cushion block provide a more stable guiding effect for the receiving mechanism, so that the rotating ring can only rotate along one side when rotating, preventing the nut from being screwed in reverse.

[0011] Further setting: One side of the rotating ring is fixedly connected with a triangular block, and the triangular block is adapted to the triangular groove.

[0012] By adopting the above technical solution, the triangular block fixedly connected to one side of the rotating ring is adapted to the triangular groove on the cushion block, so that the rotating ring can rotate more stably along the track of the triangular groove during rotation, avoiding deviation or shaking.

[0013] Further setting: The receiving groove is of a trapezoidal structure, and a baffle for preventing the nut from falling is fixedly connected to one side of the receiving groove.

[0014] By adopting the above technical solution, the trapezoidal structure of the receiving groove enables the nut to stay more stably in it after being placed, not prone to rolling or slipping, increasing the contact area between the nut and the receiving groove, thereby improving the stability of the nut during tightening.

[0015] Further setting: Both the receiving mechanism and the triangular groove are provided with two groups, and the two groups of receiving mechanisms and triangular grooves are arranged linearly.

[0016] By adopting the above technical solution, setting two groups of receiving mechanisms and triangular grooves can further enhance the connection stability between the refrigeration hard pipe and the vehicle frame. The two groups of mechanisms work simultaneously, can disperse the force, reduce the pressure borne by a single receiving mechanism, thereby reducing the risk of damage or deformation.

[0017] Further setting: One side of the connector is threadedly connected with a hard pipe, and the hard pipe is fixedly clamped with a first hose through a ferrule.

[0018] By adopting the above technical solution, one side of the connector is threadedly connected with a hard pipe. This connection method enables the hard pipe to be firmly combined with the connector, ensuring the stable transmission of the fluid inside the refrigeration system.

[0019] Further setting: The first hose is fixedly clamped and connected with a second hose through a ferrule, and one end of the second hose is fixedly connected with a threaded joint.

[0020] By adopting the above technical solution, the first hose is fixedly clamped and connected with the second hose through a ferrule, which not only ensures the tight fit between the hoses, but also effectively prevents the leakage of fluid during transmission.

[0021] Further setting: Magnets are fixedly connected to the inner wall of the receiving groove.

[0022] By adopting the above technical solution, the magnet fixedly connected to the inner wall of the receiving groove can generate a magnetic field, which generates an adsorption force on the nut placed therein, thereby effectively preventing the nut from falling out of the receiving groove during the tightening process. This not only reduces the loss and damage of the nut, but also avoids the assembly interruption and efficiency reduction caused by the nut falling.

[0023] Compared with the related technology, a refrigeration hard pipe for a new energy vehicle provided by the present utility model has the following

[0024] Beneficial effects:

[0025] The present utility model provides a refrigeration hard pipe for a new energy vehicle. By setting a receiving mechanism, a stable placement and rotation platform is provided for the nut, making it difficult for the nut to fall during the installation process, thereby improving the assembly efficiency. By using the cooperation of the triangular block and multiple triangular grooves, not only the tightening direction of the nut is guided, avoiding the possibility of wrong tightening direction, but also a loosening prevention mechanism is formed after tightening, effectively preventing the nut from loosening during the long-term use of the vehicle, and enhancing the stability and reliability of the connection.

[0026] The present utility model provides a refrigeration hard pipe for a new energy vehicle. By using a magnet, an additional adsorption force is provided for the nut inside the receiving groove, making the nut firmly adsorbed after being placed, not easy to roll or slide. During the process of rotating the nut, the adsorption effect of the magnet effectively prevents the nut from falling, avoiding the assembly interruption and efficiency reduction caused by the nut falling, and further improving the convenience and reliability of the assembly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Typical embodiments of the present utility model are shown in the drawings.

[0033] Embodiment 1:

[0034] As Figures 1 - 4 shown, a refrigeration hard pipe for a new energy vehicle of the present utility model includes a connector 1. One side of the connector 1 is fixedly connected with a vertical plate 2. A through hole 14 is opened on the vertical plate 2. A cushion block 3 is fixedly connected to the front side of the through hole 14. A groove 4 is opened on the cushion block 3. A receiving mechanism 5 is rotatably connected to the groove 4. The receiving mechanism 5 includes a rotating ring 501. One side of the rotating ring 501 is fixedly connected with a receiving groove 502. The arrangement of the cushion block 3 and the groove 4 not only provides stable support for the receiving mechanism 5, but also ensures the smoothness of the receiving mechanism 5 during rotation. The rotating ring 501 and the receiving groove 502 in the receiving mechanism 5 enable the nut to have a pre-placed position and remain stable during the tightening process, effectively preventing the nut from falling, thereby significantly improving the assembly efficiency.

[0035] As Figure 1 、 Figure 2 and Figure 3 shown, triangular grooves 6 are opened around the cushion block 3. There are multiple triangular grooves 6. The multiple triangular grooves 6 are arranged in a ring shape evenly along the central axis of the rotating ring 501. The multiple triangular grooves 6 being arranged in a ring shape evenly along the central axis of the rotating ring 501 can not only prevent the reverse screwing of the nut, but also enable the rotating ring 501 to be firmly locked after being screwed to the specified position.

[0036] As Figure 1 、 Figure 2 and Figure 3 shown, a triangular block 7 is fixedly connected to one side of the rotating ring 501. The triangular block 7 is adapted to the triangular groove 6. The adaptation of the triangular block 7 and the triangular groove 6 also plays a role in limiting the position, ensuring that the receiving mechanism 5 can be stably locked after rotating to the position, thereby improving the accuracy and reliability of the installation.

[0037] As Figure 1 、 Figure 2 and Figure 3 shown, the receiving groove 502 has a trapezoidal structure. A baffle 503 for preventing the nut from falling is fixedly connected to one side of the receiving groove 502. The baffle 503 fixedly connected to one side of the receiving groove 502 plays an effective blocking role, preventing the nut from falling out of the receiving groove 502 during the tightening or loosening process. This not only reduces the loss and damage of the nut, but also avoids the interruption of the assembly and the reduction of efficiency caused by the falling of the nut.

[0038] As Figure 1 、 Figure 2 and Figure 3As shown, there are two sets of the receiving mechanism 5 and the triangular grooves 6, and the two sets of the receiving mechanism 5 and the triangular grooves 6 are linearly arranged. The linear arrangement of the two sets of the receiving mechanism 5 and the triangular grooves 6 enables the operator to more conveniently tighten the two nuts during the installation process, improving the assembly efficiency and accuracy.

[0039] As Figure 1 and Figure 2 shown, one side of the connector 1 is threadedly connected with a hard pipe 8. The hard pipe 8 is clamped and fixed with a first hose 10 through a ferrule 9. The hard pipe 8 is clamped and fixed with a first hose 10 through a ferrule 9, which not only realizes the reliable connection between the hard pipe 8 and the first hose 10, but also facilitates subsequent maintenance and replacement. The use of the ferrule 9 enables the first hose 10 to closely fit on the hard pipe 8, effectively preventing the risk of fluid leakage.

[0040] As Figure 1 and Figure 2 shown, the first hose 10 is clamped and fixedly connected with a second hose 11 through a ferrule 9. One end of the second hose 11 is fixedly connected with a threaded joint 12. One end of the second hose 11 is fixedly connected with a threaded joint 12, enabling the second hose 11 to be conveniently connected to other components or systems, improving the scalability and flexibility of the entire refrigeration system.

[0041] In implementation, first, place the nut into the receiving groove 502, and then use a wrench to turn the receiving groove 502 and the nut so that the vertical plate 2 can be fixed on the vehicle frame. During the process of turning the nut, the triangular block 7 moves along multiple triangular grooves 6. By using the cooperation between the triangular block 7 and the triangular grooves 6, the direction will not be misaligned. When tightened, by using the cooperation between the triangular groove 7 and the triangular grooves 6, a locking mechanism is formed to prevent loosening during the long-term use of the vehicle.

[0042] Embodiment 2:

[0043] As Figure 4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: a magnet 13 is fixedly connected to the inner wall of the receiving groove 502. The adsorption of the magnet 13 also enables the nut to be more stably positioned when placed in the receiving groove 502, facilitating the assembly work of the operator.

[0044] In implementation, by using the magnet 13, the nut placed inside the receiving groove 502 is attracted to prevent the nut from falling during the process of turning the nut.

[0045] The advantages of this technical solution in practical applications include but are not limited to the following points:

[0046] 1. Through the cooperation of the receiving groove, the triangular block and the triangular groove, while providing a receiving position for the nut, a locking mechanism is formed by using the receiving groove;

[0047] 2. By using magnetic attraction, the fixing stability of the nut can be improved.

[0048] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
