[0037] In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specified and limited.

[0038] The terms "first", "second", "third", "fourth", and the like in the description and in the claims of the present application and above drawings are used for distinguishing between similar objects and not necessarily for describing a specific sequential or chronological order. The terms "comprises", "comprising", "includes", "including" and the like are synonymous with the term "containing" and are used in the sense of "including, but not limited to".

[0039] Moreover, the terms "first", "second", "third", "fourth" and the like in the description and in the claims of the present application are used for distinguishing between similar objects and not necessarily for describing a specific sequential or chronological order. The terms "comprises", "comprising", "includes", "including" and the like are synonymous with the term "containing" and are used in the sense of "including, but not limited to".

[0040] As said in the background, the air spring in the related art has the problem of inconvenience in the assembly process, which even affects the overall assembly efficiency of the vehicle.

[0041] The air spring generally refers to the air spring installed on the rear suspension of the vehicle, which provides elastic force by compressed air to absorb and buffer the vibration and impact force generated during the driving of the vehicle. The design of the air spring can be adjusted according to the load and driving conditions of the vehicle to ensure the best ride comfort and handling performance.

[0042] At present, the air spring has a plug, and the rear suspension of the vehicle has a positioning hole corresponding to the plug. Generally, the air spring is arranged below the rear suspension of the vehicle. After the vehicle is subjected to vibration or impact force, the rear suspension of the vehicle extrudes the air spring, and the air spring absorbs the impact force of the rear suspension.

[0043] When installing the air spring, the plug needs to be inserted into the positioning hole to determine the installation position of the air spring. At this time, the air spring can rotate, and manual assistance is needed to fix the air spring to avoid damage caused by rotation of the air spring during work.

[0044] This is because if the top of the air spring rotates during assembly, the air spring itself will be subjected to a certain torsion, which is easy to cause damage to the air spring when absorbing the impact force.

[0045] And in the process of assembling the air spring, manual assistance is needed to fix the air spring, which causes inconvenience in operation.

[0046] To solve the above technical problems, the embodiment of the present application provides a positioning structure, an air spring and a vehicle. In the technical scheme, the positioning structure is used for positioning a target piece on a vehicle. Here, the target piece can be an air spring. The positioning structure comprises: a positioning piece used for connecting with the target piece, the positioning piece being used for being inserted into a positioning hole on the vehicle; a guide piece connected with the positioning piece on a side away from the target piece, the guide piece being used for penetrating the positioning hole so that the positioning piece is matched with the positioning hole; and a first plane on the positioning piece, the first plane being opposite to a second plane of a side wall of the positioning hole when the positioning piece is inserted into the positioning hole, so as to limit rotation of the positioning piece. By arranging the first plane on the positioning piece opposite to the second plane on the positioning hole, the rotation of the positioning piece can be limited when the positioning piece is matched with the positioning hole, the stability of the positioning piece is improved, and the rotation of the air spring can be limited. In this way, the positioning convenience of the air spring is improved, the labor consumption is reduced, and the assembly operation of the air spring is facilitated. In addition, by arranging the guide piece, the positioning piece can be quickly matched with the positioning hole, the positioning piece has a certain guiding effect, and the assembly convenience is further improved.

[0047] It should be noted that the target piece mentioned above can be but is not limited to the air spring. The target piece can also be any other component which is positioned by matching the positioning piece with the positioning hole. Of course, the target piece can also be positioned on other target positions by the positioning structure. The target positions are not limited to the vehicle, and can also include a wall, a household appliance, a lathe and the like. The embodiment of the present application does not limit the target piece and the target position.

[0048] It should be noted that, Figures 1 to 5 The positioning structure, the air spring and the vehicle are shown in the schematic diagram. The specific structures of the remaining components of the positioning structure, the air spring and the vehicle are not limited to Figures 1 to 5 .

[0049] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments:

[0050] Referring to Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides a positioning structure used for positioning a target piece on a vehicle. The positioning structure comprises:

[0051] A positioning piece 100 is used for connecting with the target piece. The vehicle has a positioning hole 10. The positioning piece 100 is used for being inserted into the positioning hole 10. Specifically, the suspension of the vehicle has the positioning hole 10. The target piece can be an air spring 20.

[0052] The guide piece 200 is connected to the positioning piece 100 away from the target piece side, and the guide piece 200 is used to pass the positioning hole 10 to make the positioning piece 100 cooperate with the positioning hole 10.

[0053] The positioning piece 100 has a first plane 110, and the side wall of the positioning hole 10 has a second plane 11. When the positioning piece 100 is inserted into the positioning hole 10, the first plane 110 is opposite to the second plane 11 to limit the rotation of the positioning piece 100. In an example, at least one of the first plane 110 and the second plane 11 has an angle with the horizontal plane, and the first plane 110 and the second plane 11 are both vertically arranged.

[0054] In the above embodiment, by arranging the first plane 110 on the positioning piece 100 opposite to the second plane 11 on the positioning hole 10, the rotation of the positioning piece 100 can be limited when the positioning piece 100 cooperates with the positioning hole 10, the stability of the positioning piece 100 is improved, and the rotation of the air spring 20 is limited, which improves the positioning convenience of the air spring 20, reduces the labor, and facilitates the assembly operation of the air spring 20.

[0055] In addition, by arranging the guide piece 200, the positioning piece 100 can be quickly cooperated with the positioning hole 10, and the positioning piece 100 has a certain guiding effect, which further improves the assembly convenience.

[0056] In the related art, after the air spring 20 is assembled on the vehicle, in the actual working process, the positioning piece 100 may appear to fluctuate up and down in the positioning hole 10. At this time, if the air spring 20 is separated from the positioning hole 10, the air spring 20 may be damaged, which causes inconvenience to the later maintenance operation. In order to facilitate the later maintenance operation and avoid the damage of the air spring 20, the guide piece 200 extends towards the side of the positioning piece 100 away from the target piece, and the extension length of the guide piece 200 is 65-80mm. In specific implementation, the extension length of the guide piece 200 can be any one of 65.0mm, 65.1mm, 66.0mm, 70.0mm, 79.9mm, and 80.0mm. The extension length of the guide piece 200 in the embodiment of the application is 70.0mm. Compared with the prior art, the structure length in the positioning hole 10 is increased, which avoids the damage of the air spring 20 caused by the separation of the guide piece 200 and the positioning piece 100 from the positioning hole 10.

[0057] In a possible embodiment, please continue to refer to Figures 1 to 3 The positioning piece 100 also has a first arc surface 120, and the first arc surface 120 is connected to the first plane 110 in a head-to-tail manner.

[0058] The side wall of the positioning hole 10 has a second arc surface 12, and the second arc surface 12 is connected to the second plane 11 in a head-to-tail manner.

[0059] When the positioning member 100 is inserted into the positioning hole 10, the first arc surface 120 is opposite to the second arc surface 12.

[0060] In the above embodiment, by arranging the first arc surface 120 and the first plane 110 to be connected end to end, and the second arc surface 12 and the second plane 11 to be connected end to end, the smoothness of the positioning member 100 when cooperating with the positioning hole 10 can be improved, and the assembly of the air spring 20 is facilitated.

[0061] In a possible implementation, the guide member 200 has a conical surface 210, and the bottom edge of the conical surface 210 is connected to the side edge of the first arc surface 120. The conical surface 210 has a certain taper.

[0062] The cross-sectional area of the guide member 200 gradually decreases along the extension direction of the guide member 200.

[0063] In the above embodiment, by arranging the cross-sectional area of the guide member 200 to gradually decrease along the extension direction of the guide member 200, and arranging the conical surface 210, the guide member 200 as a whole can have a conical shape. When the guide member 200 is inserted into the positioning hole 10, the inner side wall of the positioning hole 10 abuts against the conical surface 210 of the guide member 200. The conical surface 210 has a certain guiding effect on the guide member 200, which can facilitate the cooperation of the positioning member 100 and the positioning hole 10.

[0064] In a possible implementation, the guide member 200 further has a third plane 220, the two sides of the third plane 220 are connected to the two sides of the conical surface 210, and the bottom edge of the third plane 220 is connected to the first plane 110.

[0065] In the above embodiment, during the process that the guide member 200 is inserted into the positioning hole 10, the third plane 220 can abut against and slide relative to the second plane 11 on the positioning hole 10. It can be understood that in the related art, when two planes abut against each other, the two planes limit each other, and the relative rotation of one of the two planes can be limited. This can avoid the rotation of the guide member 200 during assembly, so that the air spring 20 does not rotate during assembly, and does not need manual intervention in the later stage. By designing a reasonable angle of the positioning hole 10, the air spring 20 can be accurately positioned during assembly, and the assembly convenience of the air spring 20 is further improved.

[0066] In a possible implementation, the first arc surface 120 and the first plane 110 are connected in a smooth transition, and the second arc surface 12 and the second plane 11 are connected in a smooth transition.

[0067] In the above embodiments, by setting a smooth transition, stress concentration can be avoided at the connection between the first arc surface 120 and the first plane 110, and at the connection between the second arc surface 12 and the second plane 11, which helps to extend the service life of the positioning structure.

[0068] In one possible implementation, to improve the safety of the positioning structure, the guide member 200 is shaped like a boss at the end opposite to the positioning member 100. Specifically, the top of the boss is horizontal. It is understood that during the operation of the air spring 20, the guide member 200 will fluctuate up and down within the positioning hole 10. The top of the guide member 200 is positioned towards other components in the vehicle. When the impact force on the vehicle is too large, the displacement of the guide member 200 will be too large, and the guide member 200 may pierce other components, such as the rear suspension of the vehicle, thereby causing damage to the guide member 200 or other vehicle components.

[0069] In the above embodiments, by providing a boss with a horizontal surface, the risk of damage to the guide member 200 can be reduced when the top of the guide member 200 comes into contact with other vehicle components.

[0070] In one possible implementation, to improve the overall strength and quality of the positioning member 100 and the guide member 200, the positioning member 100 and the guide member 200 are integrally formed. This can improve the reliability of the positioning structure.

[0071] In one possible implementation, refer to Figure 3 and Figure 4 As shown, and in combination Figures 1 to 3 Alternatively, at least a portion of the structure of the positioning member 100 is projected toward the target member in an elliptical shape, the positioning hole 10 is an elliptical hole adapted to the positioning member 100, the positioning member 100 is connected to the top of the target member, and the positioning member 100 is inserted into the positioning hole 10.

[0072] In one example, the target component can be an air spring 20. The positioning component 100 can be inserted into the positioning hole 10 to achieve the positioning and fixing of the air spring 20. After the elliptical positioning component 100 and the elliptical positioning hole 10 are engaged, they have a certain effect of limiting rotation, preventing the air spring 20 from rotating and improving the stability of the air spring 20.

[0073] This application embodiment also provides an air spring 20, which includes a spring body and the aforementioned positioning structure. The positioning structure is disposed on the spring body, specifically at the top of the spring body. The spring body is positioned onto the vehicle via the positioning structure.

[0074] The positioning structure has been described above, and will not be described here again. The air spring 20 has all the beneficial technical effects of the positioning structure described above, and can improve assembly convenience, reduce damage risk, and prolong service life.

[0075] In one possible implementation, the embodiments of the present application also provide a vehicle, which includes a vehicle body and the air spring 20 described above arranged on the vehicle body. The air spring 20 has been described above, and has all the technical effects of the air spring 20 described above, and can improve assembly convenience of the vehicle.

[0076] It should be noted that the vehicle in the present application can refer to a large car, a small car, a special car, and the like. For example, according to the vehicle type, the car in the present application can be a sedan type, a sport utility vehicle (SUV) type, a multi-purpose vehicle (MPV) type, or other types. For a vehicle, generally, wheels, a power source, and a transmission system arranged between the wheels and the power source are provided. The transmission system can transmit power provided by the power source to the wheels to drive the wheels to rotate, thereby driving the vehicle to travel.

[0077] It should be noted that the type of the power source of the vehicle is not limited in the embodiments of the present application.
