Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a connection structure, a column, and a vehicle. Background Technology
[0002] In vehicle design, lightweighting is receiving increasing attention. The vehicle body uses materials of different strengths and weights, such as steel, aluminum alloy, and plastic. Currently, aluminum alloy or plastic materials are connected to steel by screws or adhesives. However, these connection methods have large assembly tolerances, long assembly time, and are prone to insufficient connection strength. Aluminum alloy or plastic is easy to separate from steel, leading to connection failure. Utility Model Content
[0003] This application provides a connection structure, a column, and a vehicle, which can improve the strength of the connection structure.
[0004] To achieve the above objectives, the main technical solutions adopted in this application include:
[0005] In a first aspect, embodiments of this application provide a connection structure, including a first connector, a second connector, and a limiting portion. The first connector has a first insertion groove; the second connector is inserted into the first insertion groove, and the first connector and the second connector are made of different materials; the limiting portion is disposed between the first connector and the second connector to restrict the second connector from dislodging from the first insertion groove.
[0006] In the connection structure proposed in this application embodiment, when the first connector and the second connector of different materials are connected, one end of the second connector is inserted into the first insertion groove of the first connector, and the connection strength of the first connector and the second connector is improved by the limiting part, thereby reducing the probability of the second connector coming off the first connector.
[0007] Optionally, the limiting portion includes a groove and a protrusion, one of which is provided in the first connector and the other in the second connector.
[0008] In the above embodiments, the first connector and the second connector can increase the connection strength between the first connector and the second connector by the cooperation of the groove and the protrusion, and increase the axial force between the two, thereby improving the strength of the connection structure and reducing the probability of the second connector coming out of the first insertion groove of the first connector.
[0009] Optionally, there are multiple grooves and protrusions, with each protrusion cooperating with a corresponding groove.
[0010] Optionally, along the insertion direction of the second connector, a plurality of the grooves are spaced apart, and a plurality of the protrusions are spaced apart.
[0011] Optionally, the length direction of the groove and the length direction of the protrusion are both perpendicular to the insertion direction of the second connector.
[0012] In the above embodiments, the length direction of the groove and the length direction of the protrusion are both perpendicular to the insertion direction of the second connector. This allows the force between the groove and the protrusion to be distributed along the insertion direction of the second connector, thereby increasing the force between the first connector and the second connector along the insertion direction of the second connector, and thus improving the connection strength between the first connector and the second connector.
[0013] Optionally, the first connector includes a first part and a second part, the first part enclosing the first insertion slot, the inner surface of the first part being provided with the groove, and the second part enclosing the second insertion slot.
[0014] In the above embodiments, the first connector has a first insertion slot and a second insertion slot, thereby realizing the connection between the first connector and multiple components.
[0015] Optionally, the first connector is a plastic part or an aluminum alloy part, and the second connector is a steel part.
[0016] In the above embodiments, it is possible to connect different material structures, and the connection strength between different materials can be enhanced, reducing the probability of the connection between different materials easily coming detached.
[0017] Secondly, embodiments of this application provide a column including the connection structure described in any of the above embodiments. The column in this application, having the connection structure described in any of the above embodiments, possesses the beneficial effects of the connection structure described in any of the above embodiments, and can enhance the connection strength between structures of different materials.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.
[0029] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0031] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0032] In this application, "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more (including two sets), and "multiple pieces" refers to two or more (including two pieces).
[0033] Currently, aluminum alloys or plastics are connected to steel using screws or adhesives. For example, standard parts such as nuts are embedded in cast aluminum parts or front-end module assemblies to connect with steel structures. To reduce assembly time and tolerances, steel structural components such as hot air expansion tubes are placed in the mold cavity, and other materials are then cast in. Taking aluminum alloy as an example, since the coefficient of thermal expansion of aluminum alloy is twice that of steel, the shrinkage of aluminum alloy during cooling is greater, allowing the aluminum alloy structure to firmly cover the hot air expansion tube and reducing the assembly process. However, because the aluminum alloy structure and the hot air expansion tube do not undergo chemical fusion, but only physical contact, the hot air expansion tube can easily detach axially from the aluminum alloy cavity, leading to connection failure.
[0034] In view of this, this application provides a connection structure that can improve the connection strength at the connection points of different materials, reduce the separation between parts, and reduce the probability of connection failure.
[0035] Firstly, reference Figure 1 and Figure 2 This application provides a connection structure including a first connector 1, a second connector 2, and a limiting part 3. The first connector 1 has a first insertion groove 11; the second connector 2 is inserted into the first insertion groove 11, and the first connector 1 and the second connector 2 are made of different materials; the limiting part 3 is disposed between the first connector 1 and the second connector 2 to restrict the second connector 2 from coming out of the first insertion groove 11.
[0036] When the first connector 1 and the second connector 2, which are made of different materials, are connected, one end of the second connector 2 is inserted into the first insertion slot 11 of the first connector 1, and the connection strength of the first connector 1 and the second connector 2 is enhanced by the limiting part 3, thereby reducing the probability of the second connector 2 coming off the first connector 1.
[0037] The limiting part 3 can be a bolt or other structure that connects the first connector 1 and the second connector 2; the limiting part 3 can also be a wedge-shaped structure provided on the first connector 1 and / or the second connector 2 to position and limit the connection between the first connector 1 and the second connector 2, thereby reducing the second connector 2 from coming out of the first insertion groove 11 of the first connector 1.
[0038] It should be noted that the connection structure can be between any two structures made of different materials. The connection structure can be applied to any structure that requires the connection of two different materials, such as columns, undercarriages, etc.
[0039] Optionally, refer to Figure 1 and Figure 2 The limiting part 3 includes a groove 31 and a protrusion 32, one of which is provided in the first connector 1 and the other is provided in the second connector 2.
[0040] The first connector 1 and the second connector 2 can increase the connection strength between the first connector 1 and the second connector 2 by cooperating with the groove 31 and the protrusion 32, thereby increasing the axial force between them, thus improving the strength of the connection structure and reducing the probability of the second connector 2 coming out of the first insertion groove 11 of the first connector 1.
[0041] By setting the groove 31 and the protrusion 32 to cooperate, the connection strength between the first connector 1 and the second connector 2 can be enhanced without increasing cost and weight.
[0042] In one specific embodiment, the second connector 2 is placed in the mold cavity, and the first connector 1 is die-cast onto the second connector 2, so that the first connector 1 covers the second connector 2, and the first connector 1 and the second connector 2 form an integral structure. If the outer peripheral wall of the second connector 2 is provided with a groove 31, then the inner peripheral wall of the first connector 1 is provided with a protrusion 32; if the outer peripheral wall of the second connector 2 is provided with a protrusion 32, then the inner peripheral wall of the first connector 1 is provided with a groove 31, thereby enhancing the connection strength between the first connector 1 and the second connector 2 and reducing the probability that the second connector 2 will come out of the first insertion groove 11 of the first connector 1.
[0043] Optionally, there are multiple grooves 31 and protrusions 32, with each protrusion 32 fitting into a corresponding groove 31.
[0044] Multiple limiting parts 3 are provided between the first connector 1 and the second connector 2. Each limiting part 3 includes a protrusion 32 and a groove 31. Each protrusion 32 is fitted into the corresponding groove 31, which further enhances the connection strength between the first connector 1 and the second connector 2 and reduces the probability of the second connector 2 coming out of the first insertion groove 11 of the first connector 1.
[0045] Optionally, refer to Figure 1 and Figure 2 Along the insertion direction X of the second connector 2, multiple grooves 31 are spaced apart, and multiple protrusions 32 are spaced apart.
[0046] Along the insertion direction X of the second connector 2, which is also the extension direction of the first insertion slot 11, multiple limiting parts 3 are spaced apart between the first connector 1 and the second connector 2 to increase the force between the first connector 1 and the second connector 2 along the insertion direction X, thereby improving the connection strength between the first connector 1 and the second connector 2 and reducing the probability of the second connector 2 coming out of the first insertion slot 11 of the first connector 1.
[0047] Optionally, the length direction of the groove 31 and the length direction of the protrusion 32 are both perpendicular to the insertion direction X of the second connector 2, so that the force between the groove 31 and the protrusion 32 is distributed along the insertion direction X of the second connector 2, thereby increasing the force of the first connector 1 and the second connector 2 along the insertion direction X of the second connector 2, thereby increasing the connection strength between the first connector 1 and the second connector 2, and reducing the probability of the second connector 2 coming out of the first insertion groove 11 of the first connector 1.
[0048] Optionally, refer to Figure 1 The first connector 1 includes a first part 12 and a second part 13 for connection. The first part 12 surrounds a first insertion groove 11 and the inner surface of the first part 12 is provided with a groove 31. The second part 13 surrounds a second insertion groove 14.
[0049] The first insertion slot 11 of the first part 12 is used to accommodate the second connector 2. The groove 31 on the inner surface of the first part 12 cooperates with the protrusion 32 on the outer surface of the second connector 2 to improve the connection strength between the first connector 1 and the second connector 2 and reduce the probability of the second connector 2 coming out of the first insertion slot 11 of the first connector 1. The second insertion slot 14 formed by the second part 13 can be used to accommodate the third connector. The inner surface of the second part 13 can also be provided with grooves or protrusions to cooperate with the third connector, thereby improving the connection strength between the second part 13 and the third connector.
[0050] In other words, the first connector 1 can serve as an adapter to connect multiple components together. For example, in the above embodiment, the first connector 1 connects the second connector 2 and the third connector together.
[0051] Optionally, the first connector 1 is a plastic part or an aluminum alloy part, and the second connector 2 is a steel part, so as to realize the connection between different material structures, and can enhance the connection strength between different material structures, and reduce the problem of separation between different materials.
