Description

Technical Field

[0001] This application relates to the technical field of mechanical connection, and particularly to a connection structure. Background Art

[0002] Various devices or apparatuses are usually composed of multiple structural members. When assembling and fixing two structural members, fasteners such as screws and bolts are usually used to fixedly connect the two structural members. However, some devices or apparatuses have high requirements for the internal space and appearance. At some positions inside the structural member, screw holes cannot be arranged, and through holes for installing screws cannot be provided in some areas on the outer surface of the structural member. Therefore, a connection structure is needed to fixedly connect the parts of the two structural members where it is not convenient to set fasteners and meet the requirement for connection strength. Utility Model Content

[0003] This application provides a connection structure, which can reduce the number of fasteners used and the assembly process, and achieve reliable connection of the structural members.

[0004] The connection structure provided by this application includes: a first clamping portion, a second clamping portion, a first limiting portion, and a second limiting portion. Among them, the first clamping portion is arranged on the first structural member; the second clamping portion is matched with the first clamping portion, the second clamping portion is arranged on the second structural member, and the first clamping portion is clamped with the second clamping portion to limit the movement of the first structural member and the second structural member in the first direction, and the first direction is the arrangement direction of the first structural member and the second structural member; the first limiting portion is arranged on the first structural member; the second limiting portion is arranged on the second structural member, and the second limiting portion is matched with the first limiting portion. When the first clamping portion is clamped with the second clamping portion, the second limiting portion is located inside the first limiting portion to limit the movement of the first structural member and the second structural member in the direction perpendicular to the first direction.

[0005] The connection structure provided by the present application includes a first clamping portion provided on a first structural member and a second clamping portion provided on a second structural member. The first clamping portion and the second clamping portion can be clamped to restrict the relative movement of the first structural member and the second structural member in a first direction, thereby achieving a reliable connection between the first structural member and the second structural member in the first direction. A first limiting portion is provided on the first structural member, and a second limiting portion is provided on the second structural member. During the process of clamping the first clamping portion and the second clamping portion, the second limiting portion can enter the first limiting portion, so that the movement of the first structural member and the second structural member in a direction perpendicular to the first direction can be restricted by the second limiting portion and the first limiting portion, and further the relative movement of the first structural member and the second structural member can be restricted in multiple directions. In this way, the connection structure provided by the present application can be arranged on the structural member. When connecting the first structural member and the second structural member by using the connection structure provided by the present application, the first clamping portion and the second clamping portion are clamped, and the second limiting portion is located within the first limiting portion, then the reliable connection of the portions of the first structural member and the second structural member where the connection structure is provided can be completed, the number of fasteners for fixedly connecting the first structural member and the second structural member can be reduced, and the process of installing the fasteners can also be reduced. Therefore, the connection structure provided by the present application can reduce the number of fasteners used and the assembly process, and achieve a reliable connection of the structural member.

[0006] In a possible implementation manner of the present application, the first limiting portion includes a receiving groove, and the second limiting portion includes a convex column matching the receiving groove. When the first clamping portion and the second clamping portion are clamped, at least a part of the convex column is inserted into the receiving groove.

[0007] In the technical solution of the present application, since the first limiting portion includes a receiving groove and the second limiting portion includes a convex column, the convex column can be inserted into the receiving groove along the first direction, so that the circumferential side wall of the convex column abuts against the circumferential groove wall of the receiving groove, thereby restricting the movement of the first structural member and the second structural member in a direction perpendicular to the first direction by the convex column located in the receiving groove.

[0008] In a possible implementation manner of the present application, along a second direction, the side of the receiving groove away from the first limiting portion has a notch, and the convex column can pass through the notch. The receiving groove can restrict the movement of the convex column in a third direction; the second direction is the arrangement direction of the first limiting portion and the first clamping portion, and the second direction is perpendicular to the first direction, and the third direction is perpendicular to both the first direction and the second direction.

[0009] In the technical solution of the present application, since the side of the receiving groove away from the first limiting portion along the second direction has a notch, in the process of engaging the first hook with the second hook, while the protrusion moves into the receiving groove along the first direction, the protrusion can also move into the receiving groove from the notch of the receiving groove along the second direction, which is conducive to reducing the resistance between the first hook and the second hook. In addition, the movement of the protrusion in the third direction can be limited by the receiving groove, thereby limiting the relative movement of the first structural member and the second structural member in the third direction.

[0010] In a possible implementation of the present application, along the second direction, a side of the protrusion close to the accommodating groove abuts against a groove edge of the accommodating groove to limit the first structure member and the second structure member from approaching each other along the second direction.

[0011] In the technical solution of the present application, since the side of the protrusion close to the accommodating groove along the second direction is abutted against the groove edge of the accommodating groove, the movement of the protrusion along the second direction toward the first hook can be limited by the groove edge, thereby limiting the first structural member from approaching the second structural member along the second direction.

[0012] In one possible implementation of the present application, a protrusion is provided on one of the groove wall and the boss of the accommodating groove, and a limiting groove matching the protrusion is provided on the other, and the protrusion cooperates with the limiting groove to limit the boss from escaping from the accommodating groove through the notch.

[0013] In the technical solution of the present application, since matching protrusions and limiting grooves are respectively provided on the groove wall and the boss of the accommodating groove, when the first structural member and the second structural member are subjected to vibration, etc., the cooperation of the protrusions and the limiting grooves can limit the boss from falling out of the notch of the accommodating groove, and can also limit the first hook and the second hook from being disengaged, thereby improving the reliability of the connection of the connecting structure.

[0014] In a possible implementation of the present application, along the first direction, the protruding column abuts against the receiving groove to limit the first structural member and the second structural member from approaching each other.

[0015] In the technical solution of the present application, since the protrusion and the accommodating groove can abut against each other along the first direction, the first structural member and the second structural member can be limited from approaching each other along the first direction, that is, the virtual shaking generated when the first structural member and the second structural member are pressed can be reduced.

[0016] In one possible implementation of the present application, along the second direction, there is an avoidance gap between at least one side of the free end of the protruding column away from the second structural member and the groove wall of the accommodating groove. In the process of disassembling and separating the first structural member from the second structural member, the avoidance gap forms a movement space between the protruding column and the groove wall to eliminate the restriction of the groove wall on the movement of the protruding column relative to the accommodating groove; the second direction is the arrangement direction of the first limiting portion and the first clamping portion, and the second direction is perpendicular to the first direction.

[0017] In the technical solution of the present application, since there is a clearance between the free end of the convex post and the groove wall of the receiving groove, the clearance can provide the required movement space for the movement of the free end of the convex post relative to the groove wall of the receiving groove. In this way, when disassembling the first structural member and the second structural member, it is convenient to make the convex post generate a small movement relative to the receiving groove, so as to facilitate the disassembly of the first hook and the second hook, which is beneficial to reducing the risk of damage to the connection structure under the action of external force.

[0018] In a possible implementation manner of the present application, the area of the groove opening of the receiving groove is larger than the projected area of the convex post on the receiving groove in the first direction.

[0019] In the technical solution of the present application, since the area of the groove opening of the receiving groove is larger than the projected area of the convex post on the receiving groove in the first direction, even when the first hook and the second hook start to abut and the convex post and the receiving groove are not completely aligned in the first direction, the free end of the convex post can also be inserted into the groove opening of the receiving groove first. As the first structural member and the second structural member approach each other, the convex post can be inserted into the receiving groove again. Therefore, it is convenient to quickly and accurately insert the convex post into the receiving groove.

[0020] In a possible implementation manner of the present application, the first limiting portion is connected to the first engaging portion; and / or, the second limiting portion is connected to the second engaging portion.

[0021] In the technical solution of the present application, since the first limiting portion is connected to the first engaging portion, the space occupied by the first limiting portion and the first engaging portion on the first structural member can be reduced, and since the second limiting portion is connected to the second engaging portion, the space occupied by the second limiting portion and the second engaging portion on the second structural member can be reduced.

[0022] In a possible implementation manner of the present application, there is a first abutting portion between the first engaging portion and the first limiting portion, and there is a second abutting portion between the second engaging portion and the second limiting portion; when the first engaging portion is engaged with the second engaging portion, along the first direction, the first engaging portion and the second engaging portion limit the first structural member and the second structural member from moving away from each other, and the first abutting portion abuts against the second abutting portion to limit the first structural member and the second structural member from approaching each other.

[0023] In the technical solution of the present application, since the first structural member has the first abutting portion and the second structural member has the second abutting portion, the first structural member and the second structural member can be restricted from approaching each other along the first direction through the first abutting portion and the second abutting portion, and thus the virtual shaking generated when the first structural member and the second structural member are pressed can be reduced. And making the first abutting portion located between the first engaging portion and the first limiting portion, and making the second abutting portion located between the second engaging portion and the second limiting portion is beneficial to reducing the space occupied by the connection structure.

[0024] In a possible implementation manner of the present application, the first clamping portion includes a first hook, and the second clamping portion includes a second hook that matches the first hook; in a direction perpendicular to the first direction, at least one of the first hook and the second hook can be deformed under the action of an external force.

[0025] In the technical solution of the present application, at least one of the first hook and the second hook can be deformed under the action of an external force, which not only facilitates the easy clamping of the first hook and the second hook, but also when disassembling the first structural member and the second structural member, it is not necessary to apply too much external force to deform the first hook or the second hook, and the risk of damage to the first hook and the second hook can also be reduced.

Detailed implementation manners

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will further describe the specific technical solutions of the present application in detail with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0039] In the embodiments of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0040] In addition, in the embodiments of the present application, orientation terms such as "upper", "lower", "left", and "right" are defined relative to the orientation of the components shown in the drawings. It should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, and they may change accordingly with the change of the orientation of the components placed in the drawings.

[0041] In the embodiments of the present application, unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium.

[0042] In the embodiments of the present application, the terms "include", "comprise", or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article, or device. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article, or device including the element.

[0043] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0044] Electronic equipment, mechanical equipment, etc. usually include multiple structural parts. When assembling multiple structural parts, screws are usually set in the corresponding screw columns and screw holes on the two structural parts to fix the two structural parts by screw locking, and the two structural parts are supported by the edges of the screw columns and screw holes. Or the two structural parts are fixedly connected by hooks and supporting structures. These connection structures can usually only provide reliable positioning of the two structural parts in one direction. In order to provide positioning of the two structural parts from more directions, more positioning structures need to be set in the structural parts, which will take up more space in the equipment. If larger or more screws are used for locking and fixing, more screw holes may need to be set on the appearance surface of the equipment, which will affect the aesthetics of the equipment.

[0045] The embodiment of the present application provides a connection structure, which can realize reliable connection of structural parts without fasteners, and will not affect the aesthetic appearance of the structural parts. The connection structure provided in the embodiment of the present application can be used for any two structural parts that need to be fixedly connected. For example, it can be used to fix the connection between the shell and the cover body in the electronic device, and it can also be used to fix the connection between two structural parts inside the electronic device. The embodiment of the present application does not limit the application scenarios of the connection structure. For the convenience of description and explanation, the connection structure provided in the embodiment of the present application is described below by taking the connection structure used for the first structural part (shell) and the second structural part (cover body) as an example, but it does not limit the connection structure to only be used for the connection between the shell and the cover body. Reference Figure 1 , Figure 2 and Figure 3 , Figure 1 Structural schematic diagram of the connection structure provided for this application Figure 1 , Figure 2 This is a schematic diagram of the structure of the first clamping portion and the first limiting portion in the connection structure provided in the present application. Figure 3 This is a schematic structural diagram of the second clamping portion and the second limiting portion in the connection structure provided in the present application.

[0046] The first clamping portion 11, the second clamping portion 21, the first limiting portion 12, and the second limiting portion 22 of the connection structure provided by the embodiment of the present application. Among them, the first clamping portion 11 is provided on the first structural member 1; the second clamping portion 21 is matched with the first clamping portion 11, the second clamping portion 21 is provided on the second structural member 2, and the first clamping portion 11 is clamped with the second clamping portion 21 to limit the movement of the first structural member 1 and the second structural member 2 along the first direction Z, and the first direction Z is the arrangement direction of the first structural member 1 and the second structural member 2; the first limiting portion 12 is provided on the first structural member 1; the second limiting portion 22 is provided on the second structural member 2, and the second limiting portion 22 is matched with the first limiting portion 12. When the first clamping portion 11 is clamped with the second clamping portion 21, the second limiting portion 22 is located within the first limiting portion 12 to limit the movement of the first structural member 1 and the second structural member 2 in a direction perpendicular to the first direction Z.

[0047] In the embodiment of the present application, as Figure 1 shown, the first clamping portion 11 can be provided on the first structural member 1. Correspondingly, the second clamping portion 21 can be provided on the second structural member 2. For example, the first clamping portion 11 can be provided on the structure extending along the first direction Z on the first structural member 1, and the second clamping portion 21 can be provided on the structure extending along the second direction Y on the second structural member 2. Among them, the first direction Z is the arrangement direction of the first structural member 1 and the second structural member 2, that is, the direction in which the first structural member 1 and the second structural member 2 approach each other during the assembly and installation process of the first structural member 1 and the second structural member 2.

[0048] Exemplarily, as Figure 2 shown, the first clamping portion 11 can be set to the structure of the first hook. For example, the first hook can be formed by extending from the first structural member 1 in a direction perpendicular to the first direction Z, that is, the first hook can be a convex block formed by extending in a direction perpendicular to the first direction Z. Along the direction perpendicular to the first direction Z, the surface of the first hook that is hooked with the second hook can be set as an inclined surface, that is, Figure 2 the surface extending along the third direction X on the first clamping portion 11 shown in has an included angle with the third direction X, which can facilitate the draft of the first structural member 1. Correspondingly, as Figure 3 shown, the second clamping portion 21 can be set to the structure of the second hook, and the second hook is matched with the first hook. For example, the second hook can be formed by extending from the second structural member 2 in a direction perpendicular to the first direction Z, that is, the second hook can be a convex block formed by extending in a direction perpendicular to the first direction Z. Along the direction perpendicular to the first direction Z, the surface of the second hook that is hooked with the first hook can be set as an inclined surface, that is, Figure 3The surface of the second engaging portion 21 shown in extending along the third direction X forms an angle with the third direction X, which facilitates the draft of the second structural member 2.

[0049] Another example, as Figure 2 and Figure 3 shown, corresponding chamfers can be provided on two surfaces of the first hook and the second hook that are close to each other (the two surfaces that first come into contact during the assembly of the first structural member 1 and the second structural member 2). In this way, the resistance during the deformation engagement of the first hook and the second hook can be reduced, facilitating the easy engagement of the first hook and the second hook. After the first hook and the second hook are engaged, the separation of the first structural member 1 and the second structural member 2 in the first direction Z can be restricted.

[0050] Another example, in a direction perpendicular to the first direction Z, at least one of the first hook and the second hook can be deformed under the action of an external force. As Figure 2 shown, the portion connecting the first hook and the first structural member 1 can be set as a plate-like structure. As Figure 3 shown, the portion connecting the second hook and the second structural member 2 can also be set as a plate-like structure. In this way, when the chamfers on the first hook and the second hook first come into contact and continue to apply a force along the first direction Z to the first structural member 1 and the second structural member 2, the first hook and / or the second hook can easily deform in a direction perpendicular to the first direction Z (the second direction Y shown in the figure) through the plate-like structure. In this way, not only is it convenient to easily engage the first hook and the second hook, but when disassembling the first structural member 1 and the second structural member 2, it is not necessary to apply too much external force to deform the first hook or the second hook, and the risk of damage to the first hook and the second hook can also be reduced.

[0051] In the embodiments of the present application, as Figure 2 shown, a first limiting portion 12 can also be provided on the first structural member 1. Correspondingly, as Figure 3 shown, a second limiting portion 22 matching the first limiting portion 12 can be provided on the second structural member 2. For example, the second limiting portion 22 can be set as a structure capable of accommodating the first limiting portion 12. In this way, during the engagement of the first hook and the second hook, at least a part of the second limiting portion 22 can be accommodated in the first limiting portion 12, and the second limiting portion 22 and the first limiting portion 12 can be in contact in a direction perpendicular to the first direction Z, thereby restricting the movement of the first structural member 1 and the second structural member 2 in a direction perpendicular to the first direction Z through the first limiting portion 12 and the second limiting portion 22.

[0052] Exemplarily, as Figure 2As shown, the first limiting portion 12 can be connected to the first clamping portion 11, that is, the first limiting portion 12 and the first hook are located at adjacent positions on the first structural member 1. For example, when the structures of both the first hook and the first limiting portion 12 are complete, the first hook and the first limiting portion 12 can be directly connected. For example, the first limiting portion 12 can be arranged at one end of the first hook on the first structural member 1 close to the center of the first structural member 1. As Figure 3 shown, the second limiting portion 22 can also be connected to the second clamping portion 21, that is, the second limiting portion 22 and the second hook are located at adjacent positions on the first structural member 1. For example, the second limiting portion 22 can be arranged at one end of the second hook away from the center of the second structural member 2. In this way, since the first limiting portion 12 is connected to the first clamping portion 11, the space occupied by the first limiting portion 12 and the first clamping portion 11 on the first structural member 1 can be reduced, and since the second limiting portion 22 is connected to the second clamping portion 21, the space occupied by the second limiting portion 22 and the second clamping portion 21 on the second structural member 2 can be reduced.

[0053] The connection structure provided by the embodiment of the present application includes a first clamping portion 11 arranged on the first structural member 1 and a second clamping portion 21 arranged on the second structural member 2. The first clamping portion 11 and the second clamping portion 21 can be clamped to restrict the relative movement of the first structural member 1 and the second structural member 2 in the first direction Z, so as to realize the reliable connection of the first structural member 1 and the second structural member 2 in the first direction Z. And a first limiting portion 12 is arranged on the first structural member 1, and a second limiting portion 22 is arranged on the second structural member 2. During the process of clamping the first clamping portion 11 and the second clamping portion 21, the second limiting portion 22 can enter into the first limiting portion 12, so that the movement of the first structural member 1 and the second structural member 2 in the direction perpendicular to the first direction Z can be restricted by the second limiting portion 22 and the first limiting portion 12, and further the relative movement of the first structural member 1 and the second structural member 2 can be restricted from multiple directions. In this way, the connection structure provided by the embodiment of the present application can be arranged on the structural member. When connecting the first structural member 1 and the second structural member 2 by using the connection structure provided by the embodiment of the present application, by clamping the first clamping portion 11 and the second clamping portion 21 and making the second limiting portion 22 located within the first limiting portion 12, the reliable connection of the parts of the first structural member 1 and the second structural member 2 where the connection structure is arranged can be completed. Therefore, the connection structure provided by the embodiment of the present application can reduce the number of fasteners used and the assembly process, and realize the reliable connection of the structural members.

[0054] In some possible embodiments of the present application, such as Figure 2 and Figure 3As shown, the first limiting portion 12 includes a receiving groove, and the second limiting portion 22 includes a convex column that matches the receiving groove. When the first clamping portion 11 is clamped with the second clamping portion 21, at least a part of the convex column is inserted into the receiving groove.

[0055] In the embodiment of the present application, as Figure 2 shown, the first limiting portion 12 can be set in the structural form of a receiving groove. For example, the receiving groove can be formed by extending along the first direction Z on the first structural member 1. Correspondingly, as Figure 3 shown, the second limiting portion 22 can be set in the structural form of a convex column. For example, the convex column can be formed by extending along the first direction Z from the second structural member 2, and the circumferential dimension of the convex column is matched with the circumferential dimension of the receiving groove, such as making the convex column and the receiving groove have a clearance fit in the direction perpendicular to the first direction Z. Then, the convex column can be inserted into the receiving groove along the first direction Z to limit the relative movement of the first structural member 1 and the second structural member 2 in the direction perpendicular to the first direction Z through the convex column and the receiving groove.

[0056] In the above embodiment, since the first limiting portion 12 includes a receiving groove and the second limiting portion 22 includes a convex column, the convex column can be inserted into the receiving groove along the first direction Z so that the circumferential side wall of the convex column abuts against the circumferential groove wall of the receiving groove, thereby restricting the movement of the first structural member 1 and the second structural member 2 in the direction perpendicular to the first direction Z through the convex column located in the receiving groove.

[0057] In some possible embodiments of the present application, referring to Figure 4 Figure 4 is a schematic structural view of the connection structure provided by the present application along the second direction Y. Figure 1 As Figure 1 , Figure 2 and Figure 4 shown, along the second direction Y, there is a notch 121 on the side of the receiving groove away from the first limiting portion 12, and the convex column can pass through the notch 121. The receiving groove can limit the movement of the convex column along the third direction X; the second direction Y is the arrangement direction of the first limiting portion 12 and the first clamping portion 11, and the second direction Y is perpendicular to the first direction Z, and the third direction X is perpendicular to both the first direction Z and the second direction Y.

[0058] In the embodiment of the present application, there are countless directions perpendicular to the first direction Z. The first structural member 1 and the second structural member 2 can be restricted in two intersecting directions perpendicular to the first direction Z, and thus the relative movement of the first structural member 1 and the second structural member 2 can be restricted in any direction perpendicular to the first direction Z. For example, the direction perpendicular or nearly perpendicular to the first direction Z in the arrangement direction of the first limiting portion 12 and the first clamping portion 11 can be used as the second direction Y, and the third direction X can be set to be perpendicular or nearly perpendicular to the first direction Z and perpendicular or nearly perpendicular to the second direction Y.

[0059] Exemplarily, the receiving groove can be set in a structural form with a notch 121, that is, the receiving groove is enclosed by three surfaces. For example, the notch 121 of the receiving groove can be set on one side of the first structural member 1 away from the first limiting portion 12 along the second direction Y. For example, when the receiving groove is rectangular parallelepiped-shaped, the convex post can be set as a plate-shaped structure matching the rectangular parallelepiped-shaped receiving groove. In this way, in the third direction X, the opposite sides of the convex post and the receiving groove can be respectively abutted against each other to limit the movement of the convex post in the third direction X through the receiving groove.

[0060] In the above embodiment, since the receiving groove has a notch 121 on the side away from the first limiting portion 12 along the second direction Y, during the process of engaging the first hook and the second hook, while the convex post moves into the receiving groove along the first direction Z, the convex post can also move into the receiving groove along the second direction Y through the notch 121 of the receiving groove, which is beneficial to reducing the resistance between the first hook and the second hook. And the movement of the convex post in the third direction X can be restricted by the receiving groove, so that the relative movement of the first structural member 1 and the second structural member 2 in the third direction X can be restricted.

[0061] In some possible embodiments of the present application, with reference to Figure 5 , Figure 5 is a schematic cross-sectional structure of the connection structure provided by the present application along the third direction Figure 1 . Along the second direction Y, the side of the convex post close to the receiving groove abuts against the groove edge 122 of the receiving groove to limit the first structural member 1 from approaching the second structural member 2 along the second direction Y.

[0062] In the embodiment of the present application, the receiving groove has a notch 121 on the side away from the first hook along the second direction Y, so that the receiving groove cannot limit the movement of the convex post away from the first hook in the second direction Y. However, the structures of the side of the convex post close to the first hook and the side of the receiving groove close to the first hook can be set to restrict the movement of the convex post along the second direction Y towards the first hook through the receiving groove.

[0063] Exemplarily, as Figure 5 shown, along the second direction Y, the side of the convex post close to the receiving groove can be set as an inclined surface, that is, the circumferential dimension of the free end 221 of the convex post is smaller, while the circumferential dimension of the end of the convex post connected to the second hook is larger, that is, the angle between the side of the convex post close to the receiving groove and the first direction Z is an acute angle. The groove wall of the receiving groove can extend along the first direction Z. In this way, a line contact can be formed between the side of the convex post close to the receiving groove along the second direction Y and the groove wall of the receiving groove. For example, the side wall of the convex post can be abutted against the groove edge 122 of the receiving groove, and the groove edge 122 of the receiving groove is the edge of the opening of the receiving groove along the first direction Z.

[0064] In the above embodiments, since the side of the convex post close to the receiving groove along the second direction Y abuts against the groove edge 122 of the receiving groove, the movement of the convex post along the second direction Y towards the first hook can be restricted by the groove edge 122, so that the mutual approach of the first structural member 1 and the second structural member 2 along the second direction Y can be restricted.

[0065] In some possible embodiments of the present application, a protrusion (not shown in the figure) is provided on one of the groove walls of the receiving groove and the convex post, and a limiting groove (not shown in the figure) matching the protrusion is provided on the other. The protrusion and the limiting groove cooperate to restrict the convex post from disengaging from the receiving groove through the notch 121.

[0066] In the embodiments of the present application, as Figure 5 shown, after the notch 121 is provided on the receiving groove, the convex post may move away from the first engaging portion 11 along the second direction Y. Then, a matching protrusion and limiting groove may be respectively provided on the groove wall of the receiving groove and the convex post, so as to restrict the convex post from disengaging from the receiving groove through the notch 121 along the second direction Y through the cooperation of the protrusion and the limiting groove.

[0067] Exemplarily, along the first direction Z, a protrusion may be provided on the bottom groove wall of the receiving groove. The surface of the protrusion may be an arc surface, and the axis of the protrusion extends along the third direction X. Correspondingly, a limiting groove may be provided on the surface of the free end 221 of the convex post. The limiting groove may be a wavy groove, that is, a plurality of continuously distributed grooves matching the protrusion. Alternatively, a limiting groove may be provided on the bottom groove wall of the receiving groove, and a protrusion may be provided on the surface of the free end 221 of the convex post. Or, a protrusion may be provided on the groove wall of the receiving groove extending along the first direction Z, and a limiting groove may be provided on the surface of the convex post extending along the first direction Z. At this time, the axis of the protrusion may extend along the first direction Z.

[0068] In this way, after the first hook and the second hook are engaged and the convex post is located in the receiving groove, the convex post can be restricted from disengaging from the notch 121 of the receiving groove along the second direction Y by the protrusion and the limiting groove. When disassembling the first structural member 1 and the second structural member 2, a force along the third direction X may be applied to the first structural member 1 and the second structural member 2 to separate the protrusion from the limiting groove, that is, to allow the convex post to disengage from the receiving groove through the notch 121. Or, a force along the first direction Z may be applied to the first structural member 1 and the second structural member 2 to deform and separate the first hook and the second hook, so as to pull out the convex post from the receiving groove along the first direction Z.

[0069] In the above embodiment, since matching protrusions and limiting grooves are respectively provided on the groove wall and the boss of the accommodating groove, when the first structural member 1 and the second structural member 2 are subjected to vibration, etc., the cooperation of the protrusions and the limiting grooves can limit the boss from coming out of the notch 121 of the accommodating groove, and can also limit the first hook and the second hook from being disengaged, thereby improving the reliability of the connection of the connecting structure.

[0070] In some possible embodiments of the present application, refer to Figure 6 and Figure 7 , Figure 6 Structural schematic diagram of the connection structure provided for this application Figure 2 , Figure 7 A schematic diagram of a cross-sectional structure of the connection structure provided in this application along the third direction Figure 2 Along the first direction Z, the protruding column abuts against the receiving groove to limit the first structural member 1 and the second structural member 2 from approaching each other.

[0071] In the present application embodiment, Figure 7 As shown, when the boss and the receiving groove are set, the boss and the receiving groove can be abutted along the first direction Z. Exemplarily, the depth of the receiving groove along the first direction Z and the length of the boss along the first direction Z can be set so that after the first hook and the second hook abut along the first direction Z, the free end 221 of the boss can abut against the bottom of the receiving groove along the first direction Z. In this way, the first hook and the second hook can limit the first structural member 1 and the second structural member 2 from moving away from each other along the first direction Z, while the boss and the receiving groove can limit the first structural member 1 and the second structural member 2 from moving closer to each other along the first direction Z.

[0072] In the above embodiment, since the boss and the receiving groove can abut against each other along the first direction Z, the first structural member 1 and the second structural member 2 can be limited from approaching each other along the first direction Z, that is, the virtual shaking generated when the first structural member 1 and the second structural member 2 are pressed can be reduced.

[0073] In some possible embodiments of the present application, along the second direction Y, there is an avoidance gap 223 between at least one side of the free end 221 of the boss away from the second structural member 2 and the groove wall of the accommodating groove. In the process of disassembling and separating the first structural member 1 from the second structural member 2, the avoidance gap 223 forms a movement space between the boss and the groove wall of the accommodating groove to eliminate the restriction of the groove wall of the accommodating groove on the movement of the boss relative to the accommodating groove; the second direction Y is the arrangement direction of the first limiting portion 12 and the first clamping portion 11, and the second direction Y is perpendicular to the first direction Z.

[0074] In the present application embodiment, Figure 2 , Figure 6 and Figure 7As shown, around the first direction Z, there can be groove walls in all directions of the accommodating groove, that is, the accommodating groove has only one groove opening 123 along the first direction Z (the accommodating groove does not have the notch 121 shown in Figure 2 ), so that the convex post can only exit from the accommodating groove along the first direction Z.

[0075] Exemplarily, as Figure 7 shown, an avoidance gap 223 can be provided between the convex post and the groove wall of the accommodating groove. For example, along the second direction Y, a post chamfer 222 is provided on the free end 221 of the convex post away from the second structural member 2, so as to form an avoidance gap 223 between the free end 221 of the convex post and the groove wall of the accommodating groove through the post chamfer 222, such as providing post chamfers 222 on both sides of the convex post. Alternatively, a groove can also be provided between the bottom groove wall of the accommodating groove and the groove wall perpendicular to the second direction Y, so as to form an avoidance gap 223 between the free end 221 of the convex post and the accommodating groove. In this way, during the process of disassembling the first structural member 1 and the second structural member 2, the convex post can be slightly rotated around the third direction X, so as to facilitate the separation of the first hook and the second hook. During the process of the convex post rotating slightly around the third direction X, the avoidance gap 223 can enable the free end 221 of the convex post to have sufficient movement space, so as to reduce the restriction of the movement of the free end 221 of the convex post by the groove wall of the accommodating groove.

[0076] In the above embodiment, since there is an avoidance gap 223 between the free end 221 of the convex post and the groove wall of the accommodating groove, the avoidance gap 223 can provide the required movement space for the movement of the free end 221 of the convex post relative to the groove wall of the accommodating groove. In this way, when disassembling the first structural member 1 and the second structural member 2, it is convenient for the convex post to generate a slight movement relative to the accommodating groove, so as to facilitate the disassembly of the first hook and the second hook, which is beneficial to reducing the risk of damage to the connection structure under the action of external forces.

[0077] In some possible embodiments of the present application, referring to Figure 8 、 Figure 9 and Figure 10 , Figure 8 is the structural schematic diagram of the connection structure provided by the present application Figure 3 , Figure 9 is the cross-sectional structural schematic diagram of the connection structure provided by the present application along the third direction Figure 3 , Figure 10 is the cross-sectional structural schematic diagram of the connection structure provided by the present application along the second direction Y Figure 2 . The area of the groove opening 123 of the accommodating groove is larger than the projected area of the convex post on the accommodating groove along the first direction Z.

[0078] In the embodiments of the present application, such as Figure 2 、 Figure 4 、 Figure 9 and Figure 10As shown, the slot opening 123 of the receiving slot can be set to be larger than the cross-section of the convex post, so as to facilitate the rapid and accurate insertion of the convex post into the receiving slot.

[0079] Exemplarily, as Figure 9 shown, in the second direction Y, chamfers 124 can be respectively provided on both sides of the slot opening 123 of the receiving slot, so as to increase the size of the slot opening 123 in the second direction Y through the chamfers 124. As Figure 10 shown, in the third direction X, chamfers 124 can also be respectively provided on both sides of the slot opening 123 of the receiving slot, so as to increase the size of the slot opening 123 in the third direction X through these two chamfers 124. In this way, the area of the slot opening 123 can be made larger than the projected area of the convex post on the receiving slot in the first direction Z.

[0080] In the above embodiment, since the area of the slot opening 123 of the receiving slot is larger than the projected area of the convex post on the receiving slot in the first direction Z, when the first hook and the second hook start to abut and the convex post and the receiving slot are not completely aligned in the first direction Z, the free end 221 of the convex post can also be inserted into the slot opening 123 of the receiving slot first. As the first structural member 1 and the second structural member 2 approach each other, the convex post can be inserted into the receiving slot, so it is convenient to quickly and accurately insert the convex post into the receiving slot.

[0081] In some possible embodiments of the present application, there is a first abutting portion 13 between the first engaging portion 11 and the first limiting portion 12, and there is a second abutting portion 23 between the second engaging portion 21 and the second limiting portion 22; when the first engaging portion 11 is engaged with the second engaging portion 21, along the first direction Z, the first engaging portion 11 and the second engaging portion 21 limit the first structural member 1 and the second structural member 2 from moving away from each other, and the first abutting portion 13 abuts against the second abutting portion 23 to limit the first structural member 1 and the second structural member 2 from approaching each other.

[0082] In the embodiments of the present application, as Figure 2 、 Figure 3 and Figure 6 shown, a first abutting portion 13 can also be provided on the first structural member 1, and correspondingly, a second abutting portion 23 is provided on the second structural member 2, so as to limit the first structural member 1 and the second structural member 2 from approaching each other through the first abutting portion 13 and the second abutting portion 23.

[0083] Exemplarily, as Figure 2 shown, the first abutting portion 13 can be provided in the area between the first engaging portion 11 and the first limiting portion 12 on the first structural member 1. For example, the first abutting portion 13 is set as a plane perpendicular to the first direction Z. Correspondingly, as Figure 3As shown, the second abutting portion 23 can be disposed in the region between the second engaging portion 21 and the second limiting portion 22 on the second structural member 2. For example, the second abutting portion 23 can be set as a plane perpendicular to the first direction Z. In this way, as Figure 6 shown, when the first hook and the second hook are engaged, the first structural member 1 and the second structural member 2 can be restricted from moving away from each other along the first direction Z by the first hook and the second hook, and the first structural member 1 and the second structural member 2 can be restricted from approaching each other along the first direction Z by the first abutting portion 13 and the second abutting portion 23, and the relative movement of the first structural member 1 and the second structural member 2 in the second direction Y and the third direction X can be restricted by the first limiting portion 12 and the second limiting portion 22.

[0084] In the above embodiments, since the first structural member 1 has the first abutting portion 13 and the second structural member 2 has the second abutting portion 23, the first structural member 1 and the second structural member 2 can be restricted from approaching each other along the first direction Z by the first abutting portion 13 and the second abutting portion 23, so that the virtual shaking generated when the first structural member 1 and the second structural member 2 are pressed can be reduced. And by making the first abutting portion 13 located between the first engaging portion 11 and the first limiting portion 12, and making the second abutting portion 23 located between the second engaging portion 21 and the second limiting portion 22, it is beneficial to reduce the space occupied by the connection structure.
