Generally, the connecting piece can be a bolt and a matching nut or a fastening screw. When two parts or components are fixed and connected by the connecting piece, the connecting piece is easy to scratch the parts, components or other structures, affecting the stability and reliability of the product.

[0003] Therefore, how to solve the problem of scratching the product by the connecting piece is a technical problem to be solved at present. CONTENT OF THE INVENTION

[0004] The present application aims to at least solve one of the technical problems in the related art. To this end, the present application provides a fastener, a connecting structure and a battery cell clamping device to solve the problem of scratching the product by the connecting piece in the related art.

[0005] An embodiment of the first aspect of the present application provides a fastener, comprising a first mounting seat, the first mounting seat having opposite first and second surfaces, and a first hole and a second hole communicating with each other in a depth direction, and the first hole penetrating through the first surface and the second hole penetrating through the second surface, and a projection of the second hole on the first surface is at least partially located outside a projection of the first hole on the first surface, and the depth direction intersects the first surface; wherein the first mounting seat further has a mounting structure, the mounting structure being in communication with the second hole, and a first connecting piece can be placed in the second hole through the mounting structure.

[0006] In the embodiment of the present application, by limiting the projection of the second hole on the first surface to be at least partially located outside the projection of the first hole on the first surface, when the first connecting piece is located in the second hole and fastened with other connecting pieces, the first hole can resist the first connecting piece and limit it in the second hole, so that the first connecting piece can be limited to protrude from the first surface of the first mounting seat, so that the first connecting piece will not protrude from the first surface and scratch the product, thereby improving the stability and reliability of the product.

[0007] In some embodiments, the mounting structure is a third hole, the third hole penetrating at least the second surface, and in a direction parallel to the first surface, the third hole is in communication with the second hole. By limiting the mounting structure to be a third hole and the third hole penetrating at least the second surface, the third hole can be in communication with the connecting holes of other connecting pieces, so as to realize the placement of the first connecting piece through the third hole, which is conducive to the assembly of the first connecting piece.

[0008] In some embodiments, the third hole further penetrates at least one side surface of the first mounting base, the side surface connecting the first surface and the second surface. By limiting the third hole to penetrate at least one side surface of the first mounting base, the first connecting member can be put in from the corresponding side surface, simplifying the assembly of the first connecting member and reducing the processing difficulty of the mounting structure.

[0009] In some embodiments, the first mounting base has at least two first holes arranged at intervals, and second holes and third holes corresponding to the first holes one by one, the third holes penetrating the same side surface of the first mounting base. By limiting the third holes corresponding to the first holes to penetrate the same side surface of the first mounting base, at least two first connecting members can be installed from the same side surface at one time, improving the installation efficiency.

[0010] In some embodiments, the third hole and the second hole are in communication with each other in a direction parallel to the first surface, and the depth of the third hole is greater than or equal to the depth of the second hole; in any direction parallel to the first surface, the size of the third hole is greater than or equal to the size of the first connecting member. By limiting the second hole and the third hole as described above, the first connecting member can pass through the third hole, thereby realizing the assembly of the first connecting member.

[0011] In some embodiments, the first mounting base has at least two first holes arranged at intervals, and second holes and third holes corresponding to the first holes one by one; the at least two third holes are located on the same side of the corresponding first holes, and the distance between the third holes and the corresponding first holes is equal. By the above arrangement, when the at least two first connecting members are placed in the connecting holes of other connecting members, the first mounting base can be translated to align the at least two second holes with the connecting holes, and the assembly of the at least two first connecting members can be completed at one time, improving the assembly efficiency.

[0012] In some embodiments, the third hole penetrates the first surface. By limiting the third hole to penetrate the first surface and the second surface, the first connecting member can be put in through the third hole directly from the outside of the first surface, and at the same time, the third hole is a through hole, which is convenient for observing the assembly of the first connecting member.

[0013] In some embodiments, the second hole includes a first sub-hole and a second sub-hole in communication with each other, the first sub-hole being located between the first hole and the second sub-hole, and the projection of the first sub-hole on the first surface being at least partially located outside the projection of the second sub-hole on the first surface. By limiting the projection of the first sub-hole on the first surface to be at least partially located outside the projection of the second sub-hole on the first surface, a step is formed between the first sub-hole and the second sub-hole, which limits the first part of the first connecting member to move into the second sub-hole, so that the first part is located in the first sub-hole and the second part is located in the second sub-hole and the second hole, thereby realizing the fastening connection of the first connecting member with the first mounting base and other connecting members.

[0014] The embodiment of the second aspect of the application provides a connecting structure, comprising: the fastener, the first mounting seat and the first connecting piece in the above embodiment; the second mounting seat is arranged opposite to the first mounting seat and has a fourth hole, the fourth hole is communicated with the second hole along the depth direction; the first connecting piece comprises a first part and a second part connected with each other, the first part is located in the second hole, and the second part protrudes from the second surface and is fixedly connected with the fourth hole.

[0015] In the embodiment of the application, when the first mounting seat and the second mounting seat are connected by using the first connecting piece, by limiting the orthographic projection of the second hole on the first surface outside the orthographic projection of the first hole on the first surface, the first connecting piece can be blocked from passing through the first hole, protruding from the first surface of the first mounting seat and scratching the product, thereby achieving the connecting effect while improving the stability and reliability of the product.

[0016] In some embodiments, when the second hole comprises a first sub-hole, the difference between the depth of the first sub-hole and the height of the first part along the depth direction is greater than or equal to 0.5 mm and less than or equal to 1 mm. By limiting the difference between the depth of the first sub-hole and the height of the first part to be within a certain range, a small distance is formed between the first connecting piece and the first sub-hole, so that the fastening connection of the first connecting piece can be achieved by slightly rotating the first connecting piece, thereby improving the assembly efficiency and improving the anti-loosening effect of the connecting piece.

[0017] In some embodiments, the fourth hole is a through hole or a blind hole. By limiting the fourth hole to be a through hole or a blind hole, the machining difficulty of the fourth hole is reduced while the anti-loosening problem is solved, and correspondingly, the machining difficulty of the first mounting seat and the second mounting seat is reduced, and the through hole or the blind hole is convenient to disassemble and assemble.

By limiting the fourth hole to be a through hole, the second part penetrates through the fourth hole and protrudes from the outer side of the second mounting seat, and the second connecting piece is connected with the second part protruding from the outer side of the second mounting seat, the machining difficulty of the fourth hole is reduced while the anti-loosening problem is solved, and correspondingly, the machining difficulty of the first mounting seat and the second mounting seat is reduced, and the through hole or the blind hole is convenient to disassemble and assemble.

[0019] In some embodiments, the fourth hole is a threaded blind hole, and the first connecting piece is threadedly connected with the fourth hole. By limiting the fourth hole to be a threaded blind hole, a standard part matched with the threaded blind hole can be directly used as the first connecting piece, thereby reducing the machining cost of the part and facilitating disassembly.

[0020] In some embodiments, the first part has a mounting component, a projection of the mounting component on the first surface is located within a projection of the first hole on the first surface. By adding the mounting component to the first part, a fastening tool can be used to connect with the mounting component to fasten the first connector, simplifying the assembly process of the first connector and facilitating disassembly.

[0021] In some embodiments, the mounting component is a hexagonal recess. By adding the mounting component as a hexagonal recess to the first part, a hexagonal wrench can be used to connect with the mounting component to fasten the first connector, simplifying the assembly process of the first connector and facilitating disassembly.

[0059] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0060] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily independent or alternative embodiments to each other. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0061] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0062] In the description of the embodiments of the present application, the term "a plurality of" refers to two or more (including two), and similarly, "a plurality of groups" refers to two or more groups (including two groups), and "a plurality of pieces" refers to two or more pieces (including two pieces).

[0063] In the description of the embodiments of the present application, the orientations or positional relationships indicated by the technical terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0064] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the technical terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium, or can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0065] In the related art, a connecting piece is often used, wherein the connecting piece is a general term for a kind of mechanical parts used when two or more parts or components are fastened and connected into a whole. When the connecting piece is used to fix and connect two parts or components, the connecting piece is easy to scratch the parts, components or other structures, affecting the stability and reliability of the product.

[0066] Therefore, how to solve the problem of the connecting piece scratching the product is a technical problem that needs to be solved at present.

[0067] Generally, the connecting piece can be a bolt and a matching nut or a fastening screw. For example, when a bolt and a nut are used as connecting pieces to fix and connect a first plate body and a second plate body, the nut of the bolt is attached to the upper surface of the first plate body, the screw rod of the bolt penetrates through the first plate body and the second plate body, and protrudes outward from the second plate body, and is fixed and connected with the nut. When the product including the first plate body and the second plate body is subjected to mechanical vibration, the connection between the bolt and the nut is easy to loosen, and the bolt is easy to fall onto the upper surface of the first plate body, thereby scratching the product and affecting the stability and reliability of the product.

[0068] Therefore, how to solve the problem of the connecting piece scratching the product is a technical problem that needs to be solved by those skilled in the art at present.

[0069] To solve the problem of scratching the product by the connecting piece, the application provides a fastener, which comprises a first mounting base, the first mounting base has opposite first and second surfaces and first and second holes which are in communication with each other in a depth direction, the first hole penetrates the first surface, the second hole penetrates the second surface, the projection of the second hole on the first surface is at least partially outside the projection of the first hole on the first surface, and the depth direction intersects the first surface; wherein the first mounting base further has a mounting structure, the mounting structure is in communication with the second hole, and the first connecting piece can be placed in the second hole through the mounting structure. In this way, in the process of mechanical vibration, the first connecting piece is limited to protrude from the first surface of the first mounting base by the first hole, thereby solving the problem of scratching the product due to the loosening of the connecting piece.

[0070] The fastener, connecting structure and connecting method thereof disclosed by the application can be applied to various mechanical equipment, for example, but not limited to, battery production equipment, and can also be applied to other technical fields which need to fasten two or more parts or components by using connecting pieces. In this way, the problem of scratching the product by the connecting piece can be improved, thereby improving the stability and reliability of the product.

[0071] The cell clamping equipment disclosed by the application can be applied to battery production equipment. In this way, the problem of scratching the product by the connecting piece can be improved, thereby improving the stability and reliability of the cell clamping equipment.

[0072] The application provides a fastener, Figure 1 The structure of the fastener of some embodiments of the application is shown in the figure, Figure 2 The structure of the fastener of some embodiments of the application is shown in the figure, Figure 1 The sectional view along A1-A1 is shown in the figure. Referring to Figure 1 The sectional view along A1-A1 is shown in the figure. Referring to Figure 2 The fastener comprises a first mounting base 110. The first mounting base 110 has opposite first and second surfaces C1 and C2 and first and second holes 111 and 112 which are in communication with each other in a depth direction (the depth direction has no specific direction, for example, the Z direction), the first hole 111 penetrates the first surface C1, the second hole 112 penetrates the second surface C2, the projection of the second hole 112 on the first surface C1 is at least partially outside the projection of the first hole 111 on the first surface C1, and the depth direction intersects the first surface C1. The first mounting base 110 further has a mounting structure, the mounting structure is in communication with the second hole 112, and the first connecting piece 130 can be placed in the second hole 112 through the mounting structure.

[0073] Exemplarily, as shown in Figure 1 The depth direction is perpendicular to the first surface. It should be noted that in the application, the depth direction is not particularly limited, and the depth direction can not be perpendicular to the first surface.

[0074] In some embodiments, the first mounting base 110 is a block structure or a plate structure. For example, as shown in Figure 1 The first mounting base 110 is a block structure.

[0075] In the embodiments of the present application, the first mounting base 110 is provided with a first hole 111 and a second hole 112 which are in communication with each other. One end of the first hole 111 passes through the first surface C1 of the first mounting base 110, one end of the second hole 112 passes through the second surface C2 of the first mounting base 110, and the other end of the first hole 111 is in communication with the other end of the second hole 112.

[0076] In one implementation manner of the embodiments of the present application, the depth direction (for example, the Z direction) is perpendicular to the first surface C1, that is, the depth directions of the first hole 111 and the second hole 112 are both perpendicular to the first surface C1. Since the first hole 111 and the second hole 112 can be made by drilling, the drilling tool can be placed perpendicular to the first surface C1, which is more convenient.

[0077] In another implementation manner of the embodiments of the present application, the depth direction (for example, the Z direction) intersects with the first surface C1 but is not perpendicular to the first surface C1.

[0078] In some embodiments of the present application, as shown in Figure 2 The first hole 111 and the second hole 112 are coaxially arranged, that is, the center line K1 of the first hole 111 coincides with the center line K2 of the second hole 112. Since the first hole 111 and the second hole 112 are coaxially arranged, the machining of the first hole 111 and the second hole 112 can be completed in the same direction at one time, which improves the machining efficiency.

[0079] In the embodiments of the present application, the first mounting base 110 also has a mounting structure, which can be a mounting opening on the first mounting base 110, used for the first connecting piece 130 to pass through, so as to put the first connecting piece 130 in. In some embodiments, the mounting structure is a mounting hole or a mounting slot used for the first connecting piece 130 to pass through.

[0080] In the embodiment of the present application, the projection of the second hole 112 on the first surface C1 is at least partially outside the projection of the first hole 111 on the first surface C1, i.e., there is a partial area of the second hole 112 that does not overlap with the first hole 111. Generally, the first mounting seat 110 can be connected with other connecting members having connecting holes through the first connecting member, wherein a part of the first connecting member 130 is located in the second hole 112 and the connecting hole, and the first mounting seat 110 and the other connecting member are fastened through the first connecting member 130. Based on this, when the first connecting member 130 having the same size as the second hole 112 is present in the second hole 112, because there is a partial area of the second hole 112 that does not overlap with the first hole 111, the size of the overlapping connection surface between the first hole 111 and the second hole 112 is smaller than the size of the first connecting member 130, and when the first connecting member 130 moves towards the first hole 111, the first connecting member 130 can be blocked from penetrating into the first hole 111, so that the first connecting member 130 cannot protrude from the first surface C1.

[0081] In some other embodiments, the center line K1 of the first hole 111 is parallel to and does not overlap with the center line K2 of the second hole 112. Because the projection of the second hole 112 on the first surface C1 is at least partially outside the projection of the first hole 111 on the first surface C1, the first connecting member 130 located in the second hole 112 cannot penetrate through the first hole 111, and the first connecting member 130 can be tightened through the first hole 111, while the first connecting member 130 is limited to protrude from the first surface C1.

[0082] In some other embodiments, the center line K1 of the first hole 111 can intersect with the center line K2 of the second hole 112, which can be set according to requirements, and the present application does not limit this.

[0083] In the embodiment of the present application, by limiting the projection of the second hole 112 on the first surface C1 to be at least partially outside the projection of the first hole 111 on the first surface C1, when the first connecting member 130 is located in the second hole 112 and fastened with the other connecting member, the first hole 111 can resist the first connecting member and limit it in the second hole 112, so that the first connecting member 130 can be limited to protrude from the first surface C1 of the first mounting seat 110, so that the first connecting member 130 does not protrude from the first surface C1 and scratch the product, thereby improving the stability and reliability of the product.

[0084] According to some embodiments of the present application, the mounting structure is a third hole 113, the third hole 113 at least penetrates through the second surface C2, and in the direction parallel to the first surface C1 (for example, the X direction in FIG. 1), the third hole 113 communicates with the second hole 112. Figure 1

[0085] ​In the embodiments of the present application, the mounting structure is the third hole 113, the third hole 113 at least penetrates the second surface C2, and the first connecting piece 130 can pass through the third hole 113, and meanwhile, the third hole 113 is in communication with the second hole 112, and the first connecting piece 130 can be put into the second hole 112 by moving the first connecting piece 130.

[0086] In some embodiments, the third hole 113 can penetrate the first surface C1 of the first mounting seat 110, and correspondingly, the first connecting piece 130 needs to pass through the third hole 113 from the first surface C1, and the orthographic projection of the first connecting piece 130 on the first surface C1 is located in the orthographic projection of the third hole 113 on the first surface C1.

[0087] In other embodiments, the third hole 113 can penetrate the side surface of the first mounting seat 110.

[0088] In the embodiments of the present application, by limiting the mounting structure to be the third hole 113 and the third hole 113 at least penetrates the second surface C2, the third hole 113 can be in communication with the connecting holes of other connecting pieces, so that the first connecting piece 130 can be put into the third hole 113, which is beneficial to the assembly of the first connecting piece 130.

[0089] In the embodiments of the present application, referring to Figure 1 , the third hole 113 also penetrates at least one side surface of the first mounting seat 110, and the side surface connects the first surface C1 and the second surface C2.

[0090] In the embodiments of the present application, the side surface is a certain side surface on the first mounting seat 110, which connects the first surface C1 and the second surface C2. For example, as shown in Figure 1 , the side surface is the YZ plane. Wherein, the X direction, the Y direction and the Z direction are perpendicular to each other.

[0091] In some embodiments, the third hole 113 penetrates one side surface of the first mounting seat 110, and the first connecting piece 130 can be put into the third hole 113 from the side surface.

[0092] In other embodiments, the third hole 113 penetrates two side surfaces of the first mounting seat 110, and the two side surfaces are oppositely arranged, and the first connecting piece 130 can be put into the third hole 113 from any one of the two side surfaces.

[0093] For example, referring to Figure 1 and Figure 2 , the third hole 113 is a part of the second hole 112 extending to the side surface of the first mounting seat 110, one end of the third hole 113 is in communication with the second hole 112, and the other end penetrates at least one side surface of the first mounting seat 110. At this time, the size of the third hole 113 is consistent with the size of the second hole 112, and the first connecting piece 130 can pass through the third hole 113.

[0094] In the embodiments of the present application, when the size of the third hole 113 is consistent with the size of the second hole 112, the third hole 113 and the second hole 112 can be simultaneously manufactured, since the third hole 113 and the second hole 112 are T-shaped as viewed from the side of the first mounting base 110, a T-shaped cutter can be used to simultaneously manufacture the third hole 113 and the second hole 112.

[0095] In the embodiments of the present application, by limiting the third hole 113 to penetrate at least one side of the first mounting base 110, the first connecting member 130 can be put in from the corresponding side, simplifying the assembly of the first connecting member 130 and reducing the processing difficulty of the mounting structure.

[0096] In the embodiments of the present application, the first mounting base 110 has at least two first holes 111 arranged at intervals, and second holes 112 and third holes 113 corresponding to the first holes 111 one by one, respectively, and the third holes 113 penetrate the same side of the first mounting base 110.

[0097] It should be understood that the number and position of the second holes 112 and the number and position of the third holes 113 correspond to the number and position of the first holes 111, respectively. In the embodiments of the present application, the number of the first holes 111 is at least two, and correspondingly, the number of the second holes 112 and the third holes 113 is at least two. Correspondingly, the number of the first connecting members 130 is at least two, and the at least two first connecting members 130 are respectively located in the corresponding second holes 112 and the connecting holes, for connecting the first mounting base 110 with other connecting structures.

[0098] For example, referring to Figure 1 and Figure 2 , the first mounting base 110 has two first holes 111 arranged at intervals, and two second holes 112 and third holes 113 corresponding to the two first holes 111. Since the third holes 113 penetrate the same side of the first mounting base 110, the two first connecting members 130 can be simultaneously put in from the third holes 113, and the assembly of the two first connecting members 130 is completed at one time.

[0099] In the embodiments of the present application, by limiting the third holes 113 corresponding to the first holes 111 to penetrate the same side of the first mounting base 110, at least two first connecting members 130 can be installed at one time from the same side, improving the installation efficiency.

[0100] As shown in Figure 3 , it is a structural schematic diagram of another fastener in some embodiments of the present application. As shown in Figure 4 , it is a sectional view along A2-A2 in Figure 3 . As shown in Figure 5 , it is a sectional view along A3-A3 in Figure 3A cross-sectional view along A2-A2. In some embodiments, the third hole 113 communicates with the second hole 112 in a direction parallel to the first surface C1 (e.g., the X direction), and the depth of the third hole 113 is greater than or equal to the depth of the second hole 112; in any direction parallel to the first surface C1, the size of the third hole 113 is greater than or equal to the size of the first connector 130.

[0101] In this embodiment of the application, since the size of the third hole 113 is greater than or equal to the size of the first connector 130 in any direction parallel to the first surface C1, the first connector 130 can pass through the third hole 113.

[0102] For example, see Figures 3 to 5 The third hole 113 penetrates the second surface C2 of the first mounting base 110 along the depth direction (e.g., the Z direction) and communicates with the second hole 112 in a direction parallel to the first surface C1. The depth of the third hole 113 is greater than or equal to the depth of the second hole 112. When the first connector 130 is located in the third hole 113, it can be moved from the third hole 113 to the second hole 112 by translation. At this time, the first connector 130 is located in the connection hole between the second hole 112 and other connectors, and the first connector 130 can be fastened.

[0103] In some embodiments, by restricting the second hole 112 and the third hole 113 as described above, the first connector 130 can pass through the third hole 113, thereby enabling the assembly of the first connector 130.

[0104] In some embodiments, the first mounting base 110 has at least two spaced-apart first holes 111, and second holes 112 and third holes 113 corresponding to the first holes 111 respectively. In some embodiments, at least two third holes 113 are located on the same side of the corresponding first holes 111, and the distance between the third holes 113 and the corresponding first holes 111 is equal.

[0105] In this embodiment, since at least two third holes 113 are located on the same side of the corresponding first holes 111, the third holes 113 and the second holes 112 are interconnected, and the distance between the third holes 113 and the corresponding first holes 111 is equal, when at least two first connectors 130 are placed in the connecting holes of other connectors, the translation of the first mounting base 110 can make at least two second holes 112 aligned with the connecting holes, and then the first connectors 130 are fastened through the first holes 111, thus completing the assembly of at least two first connectors 130 in one go.

[0106] Among them, at least two third holes 113 are located on the same side of their corresponding first holes 111, indicating that the lines connecting the paired third holes 113 and the first holes 111 are parallel.

[0107] It should be understood that the number and position of the second holes 112 and the number and position of the third holes 113 correspond to the number and position of the first holes 111 respectively. In the embodiments of the present application, the number of the first holes 111 is at least two, and the number of the second holes 112 and the third holes 113 corresponds to the number of the first holes 111 respectively. Correspondingly, the number of the first connecting members 130 corresponds to the number of the first holes 111, and at least two first connecting members 130 are respectively located in the corresponding second holes 112 for connecting the first mounting base 110 with other connecting structures.

[0108] In some embodiments, the plurality of third holes 113 can be arranged in different manners. For example, the centers of the plurality of third holes 113 are located on a line. For example, the centers of the plurality of third holes 113 form a parallelogram or a rectangle. For example, referring to FIG. 1, the four third holes 113 are arranged in a matrix. Figure 3 Since the four third holes 113 are arranged in a matrix and the distance between the four third holes 113 and the corresponding first holes 111 is equal, when the four first connecting members 130 are placed in the connecting holes of other connecting members, the first mounting base 110 can be translated to align the four second holes 112 with the connecting holes, and then the first connecting members 130 can be fastened through the first holes 111 to complete the assembly of the four first connecting members 130 at one time.

[0109] For example, the center line of the third hole 113 is parallel to the center line K1 of the first hole 111. This is beneficial for processing the holes on the first mounting base 110 and reduces the processing difficulty of the holes.

[0110] In the embodiments of the present application, through the above arrangement, when the at least two first connecting members 130 are placed in the connecting holes of other connecting members, the first mounting base 110 can be translated to align the at least two second holes 112 with the connecting holes, and the assembly of the at least two first connecting members 130 can be completed at one time, thereby improving the assembly efficiency.

[0111] In some embodiments, the third hole 113 penetrates the first surface C1.

[0112] When the third hole 113 only penetrates the second surface C2, the first connecting member 130 can be placed into the connecting hole of other connecting members, and then the first mounting base 110 is buckled on the first connecting member 130 so that the first connecting member 130 is partially located in the third hole 113, and then the first mounting base 110 is translated so that the first connecting member 130 is located in the connecting hole and the second hole 112.

[0113] In other implementations, referring to FIG. 2, the first mounting base 110 is provided with a plurality of first holes 111, a plurality of second holes 112 and a plurality of third holes 113. Figure 6As shown in FIG. 7, when the third hole 113 penetrates the first surface C1 and the second surface C2, the first connecting member 130 can be directly put into the third hole 113 from the outside of the first surface C1, so that the first connecting member 130 is located in the third hole 113 and the connecting hole, and then the first mounting base 110 is translated, so that the first connecting member 130 is located in the connecting hole and the second hole 112.

[0114] In the embodiment of the present application, by limiting the third hole 113 to penetrate the first surface C1 and the second surface C2, the first connecting member 130 can be directly put into the third hole 113 from the outside of the first surface C1, and meanwhile, the third hole 113 is a through hole, which is convenient for observing the assembly of the first connecting member 130.

[0115] In some embodiments, the second hole 112 includes a first sub-hole 1121 and a second sub-hole 1122 which are in communication with each other, the first sub-hole 1121 is located between the first hole 111 and the second sub-hole 1122, and a projection of the first sub-hole 1121 on the first surface C1 is at least partially outside a projection of the second sub-hole 1122 on the first surface C1.

[0116] Referring to Figure 4 and Figure 5 , the second hole 112 includes a first sub-hole 1121 and a second sub-hole 1122, one end of the first sub-hole 1121 communicates with the first hole 111, and one end of the second sub-hole 1122 penetrates the second surface C2, and the other end of the first sub-hole 1121 and the other end of the second sub-hole 1122 communicate with each other.

[0117] Since the first part 131 of the first connecting member 130 is located in the first sub-hole 1121, a projection of the first sub-hole 1121 on the first surface C1 is at least partially outside a projection of the second sub-hole 1122 on the first surface C1, that is, the projection of the first sub-hole 1121 exists in a region which does not overlap with the projection of the second sub-hole 1122. Therefore, the size of the connecting surface between the first sub-hole 1121 and the second sub-hole 1122 is smaller than the size of the first part 131 of the first connecting member 130, in other words, there is a step between the first sub-hole 1121 and the second sub-hole 1122, which can limit the movement of the first part 131 of the first connecting member 130 into the second sub-hole 1122, so that the first connecting member 130 will not completely fall into the connecting hole, thereby achieving the fastening connection of the first connecting member 130 to the first mounting base 110 and other connecting members.

[0118] In some embodiments, the cross-sectional shape of the first sub-hole 1121 and the second sub-hole 1122 along a plane parallel to the depth direction (e.g. Z direction) of the first hole 111 is T-shaped. With the first sub-hole 1121 and the second sub-hole 1122 being T-shaped in cross-section, a step is formed between the first sub-hole 1121 and the second sub-hole 1122, and the first portion 131 of the first connecting member 130 is restricted from moving into the second sub-hole 1122 by the step.

[0119] In the embodiments of the present application, by restricting the projection of the first sub-hole 1121 on the first surface C1 to be at least partially outside the projection of the second sub-hole 1122 on the first surface C1, a step is formed between the first sub-hole 1121 and the second sub-hole 1122, and the first portion 131 of the first connecting member 130 is restricted from moving into the second sub-hole 1122 by the step, so that the first portion 131 is located in the first sub-hole 1121, and the second portion 132 is located in the second sub-hole 1122 and the second hole 112, thereby achieving the fastening connection of the first mounting base 110 and other connecting members by the first connecting member 130.

[0120] The embodiments of the second aspect of the present application provide a connecting structure, as shown in Figure 6 , which is a structural schematic diagram of a connecting structure according to some embodiments of the present application. As shown in Figure 7 , which is an exploded structural schematic diagram of a connecting structure according to some embodiments of the present application. Referring to Figure 6 and Figure 7 , the connecting structure 100 comprises the fastener, the first mounting base 110 and the first connecting member 130 of the above embodiments. As shown in Figure 8 , which is a structural schematic diagram of a second mounting base 120 according to some embodiments of the present application. In some embodiments, referring to Figure 8 , the second mounting base 120 is arranged opposite to the first mounting base 110 and has a fourth hole 121, which is in communication with the second hole 112 along the depth direction (e.g. Z direction). In some embodiments, the first connecting member 130 comprises a first portion 131 and a second portion 132 connected to each other, the first portion 131 is located in the second hole 112, and the second portion 132 protrudes from the second surface C2 and is fixedly connected to the fourth hole 121.

[0121] In the embodiments of the present application, the second mounting base 120 can be a block structure or a plate structure. Exemplarily, referring to Figure 6 and Figure 7The second mounting base 120 is a block structure, L-shaped, while the first mounting base 110 is a plate structure. The first mounting base 110 and the second mounting base 120 are attached to the second surface C2, and simultaneously, the first mounting base 110 and the second mounting base 120 are attached to the side of the first mounting base 110 that protrudes from the second surface C2. Other connecting structures can be the second mounting base 120, and correspondingly, the connecting hole in these other connecting structures is the fourth hole 121. When the first connector 130 is located in the second hole 112 and the fourth hole 121, the first mounting base 110 and the second mounting base 120 can be securely connected by the first connector 130.

[0122] In other embodiments, only the second surface C2 of the first mounting base 110 is in contact with the second mounting base 120, and the side surface of the first mounting base 110 is not in contact with the second mounting base 120.

[0123] like Figure 9 The diagram shown is a schematic representation of another connection structure according to some embodiments of this application. Figure 10 As shown, Figure 9 A three-dimensional sectional view along line A3-A3. (See attached image.) Figure 11 As shown Figure 9 A cross-sectional view along line A3-A3. In this embodiment, the second mounting base 120 can be a block structure or a plate structure. For example, as shown... Figure 9 As shown, the second mounting base 120 and the first mounting base 110 are both plate structures, and the first mounting base 110 and the second mounting base 120 are attached to the second surface C2. Other connecting structures can be the second mounting base 120, and correspondingly, the connecting hole in the other connecting structure is the fourth hole 121.

[0124] In some embodiments, the first connector 130 may be a bolt or a set screw, etc. Exemplarily, the first connector 130 is a bolt, the first portion 131 of the first connector 130 is a nut, and the second portion 132 of the first connector 130 is a screw. The screw of the first connector 130 is located in the second hole 112 and the fourth hole 121, and is threadedly connected to the nut or the fourth hole 121, thereby fastening the first mounting base 110 and the second mounting base 120.

[0125] In this embodiment of the application, when the first connector 130 is used to connect the first mounting base 110 and the second mounting base 120, by limiting the orthographic projection of the second hole 112 on the first surface C1 to outside the orthographic projection of the first hole 111 on the first surface C1, the first connector 130 can be prevented from passing through the first hole 111 and protruding from the first surface C1 of the first mounting base 110, thus preventing scratches on the product. While achieving the connection function, the stability and reliability of the product are improved.

[0126] In some embodiments, referring to Figure 10 and Figure 11 When the second hole 112 includes the first sub-hole 1121, the difference between the depth H1 of the first sub-hole 1121 and the height H2 of the first portion 131 along the depth direction (e.g., the Z direction) is greater than or equal to 0.5 mm and less than or equal to 1 mm.

[0127] In the embodiments of the present application, the orthographic projection of the first portion 131 of the first connecting member 130 on the first surface C1 and the orthographic projection of the second sub-hole 1122 on the first surface C1 at least partially do not coincide, that is, there is a step between the first sub-hole 1121 and the second sub-hole 1122, which limits the movement of the first portion 131 of the first connecting member 130 into the second sub-hole 1122, so that the first portion 131 is always located in the first sub-hole 1121, and the first connecting member 130 will not completely fall into the fourth hole 121.

[0128] Illustratively, referring to Figure 10 and Figure 11 The depth H1 of the first sub-hole 1121 is greater than the height H2 of the first portion 131 along the depth direction (e.g., the Z direction), and when the first portion 131 is located in the first sub-hole 1121, the first portion 131 can have a movable space in the first sub-hole 1121, which is conducive to the tightening and disassembly of the first connecting member 130.

[0129] In the embodiments of the present application, the difference between the depth H1 of the first hole 111 and the height H2 of the first portion 131 is greater than or equal to 0.5 mm and less than or equal to 1 mm, and when the first connecting member 130 is installed into the second hole 112 and the third hole 113 through the mounting structure, due to the action of the thrust or gravity during assembly, the first portion 131 adheres to the bottom wall of the first sub-hole 1121, and the distance between the upper surface of the first portion 131 and the upper wall of the first sub-hole 1121 is the difference between the depth H1 of the first sub-hole 1121 and the height H2 of the first portion 131, that is, the distance between the upper surface of the first portion 131 and the upper wall of the first sub-hole 1121 is greater than or equal to 0.5 mm and less than or equal to 1 mm. Based on this, when the first connecting member 130 is placed in the second hole 112 and the third hole 113, there is a small distance (0.5-1 mm) between the upper surface of the first portion 131 and the upper wall of the first sub-hole 1121, and only a slight rotation (e.g., only half a turn) of the first connecting member 130 is needed to achieve the fastening of the first connecting member 130. At the same time, due to the small distance between the upper surface of the first portion 131 and the upper wall of the first sub-hole 1121, the movement of the first connecting member 130 can be limited, that is, the loosening of the first connecting member 130 can be reduced.

[0130] In the embodiment of the present application, by limiting the difference between the depth of the first sub-hole 1121 and the height of the first part 131, a small distance is formed between the first connecting piece 130 and the first sub-hole 1121, and only a slight rotation of the first connecting piece 130 is needed to achieve the fastening connection of the first connecting piece 130, thereby improving the assembly efficiency and the anti-loosening effect of the connecting piece.

[0131] In some embodiments, the fourth hole 121 is a through hole or a blind hole.

[0132] In some embodiments, the fourth hole 121 is a blind hole, i.e., the fourth hole 121 does not penetrate the outer side of the second mounting seat 120. When the first connecting piece 130 is located in the fourth hole 121, the first connecting piece 130 is fastened to the fourth hole 121 and located in the fourth hole 121, and does not protrude outward from the second mounting seat 120.

[0133] In some embodiments, the fourth hole 121 is a through hole, i.e., the fourth hole 121 penetrates the outer side of the second mounting seat 120. When the first connecting piece 130 is located in the fourth hole 121, the first connecting piece 130 is arranged in the fourth hole 121 and protrudes outward from the second mounting seat 120.

[0134] In the embodiment of the present application, by limiting the fourth hole 121 to be a through hole or a blind hole, the problem of scratching the product is solved, the processing difficulty of the fourth hole 121 is reduced, and correspondingly, the processing difficulty of the first mounting seat 110 and the second mounting seat 120 is reduced, and the through hole or the blind hole connection is convenient for disassembly and assembly.

[0135] In some embodiments, the fourth hole 121 is a through hole, and the connecting structure 100 further includes a second connecting piece 140, the second part 132 penetrates the fourth hole 121 and protrudes outward from the second mounting seat 120, and the second connecting piece 140 is connected with the second part 132 protruding outward from the second mounting seat 120.

[0136] In the embodiment of the present application, when the first connecting piece 130 is located in the fourth hole 121, the first connecting piece 130 is located in the second hole 112 and the fourth hole 121 and protrudes outward from the second mounting seat 120, the second connecting piece is fastened to the part protruding outward from the second mounting seat 120, and the second connecting piece is in contact with the outer side of the second mounting seat 120 and presses the second mounting seat 120.

[0137] In some embodiments, the first connecting piece 130 is a bolt, and the second connecting piece 140 can be a nut, the nut is fastened to the threaded rod protruding outward, and is in contact with the outer side of the second mounting seat 120 and presses the second mounting seat 120.

[0138] In some embodiments, the inner wall of the fourth hole 121 is also provided with threads, and the first connecting piece 130 can be threadedly connected with the fourth hole 121 to fasten the first mounting seat 110 and the second mounting seat 120.

[0139] In the embodiments of the present application, by limiting the fourth hole 121 to be a through hole, the second part 132 penetrates through the fourth hole 121 and protrudes outward from the second mounting seat 120, and by adding the second connecting piece, the second connecting piece is connected with the second part 132 protruding outward from the second mounting seat 120, the problem of scratching the product can be solved, and the machining difficulty of the fourth hole 121 can be reduced, and correspondingly, the machining difficulty of the first mounting seat 110 and the second mounting seat 120 can be reduced, and the disassembly and assembly are facilitated.

[0140] In some embodiments, the fourth hole 121 is a threaded blind hole, and the first connecting piece 130 is threadedly connected with the fourth hole 121.

[0141] In the embodiments of the present application, when the first connecting piece 130 is located in the fourth hole 121, the first connecting piece 130 is located in the second hole 112 and the fourth hole 121 and does not protrude outward from the second mounting seat 120, and the first connecting piece 130 is in fastening connection with the fourth hole 121. The depth of the fourth hole 121 is less than the thickness of the second mounting seat 120.

[0142] In some embodiments, the first connecting piece 130 is a tight screw, the threads of the tight screw match the threads of the inner wall of the fourth hole 121, and the tight screw is threadedly connected with the fourth hole 121.

[0143] In the embodiments of the present application, by limiting the fourth hole 121 to be a threaded blind hole, a standard part matching the threaded blind hole can be directly used as the first connecting piece 130, the machining cost of the parts is reduced, and the disassembly is facilitated.

[0144] In some embodiments, the first part 131 has a mounting component 133, and a projection of the mounting component 133 on the first surface C1 is located within a projection of the first hole 111 on the first surface C1.

[0145] In the embodiments of the present application, the first part 131 is provided with the mounting component 133, which can be connected with a fastening tool to fasten the first connecting piece 130. In some embodiments, the mounting component 133 is a groove or a protrusion. A fastening tool matched with the groove or the protrusion can be used to connect with the mounting component 133 to fasten the first connecting piece 130.

[0146] In some embodiments, the mounting component 133 is located on one side of the first part 131 close to the first hole 111.

[0147] In the embodiments of the present application, the mounting component 133 is added to the first part 131, and a fastening tool is used to connect with the mounting component 133 to fasten the first connecting piece 130, which simplifies the assembly process of the first connecting piece 130 and facilitates disassembly.

[0148] In some embodiments, the mounting component 133 is a hexagonal recess.

[0149] For example, referring to Figure 10 and Figure 11 , the mounting component 133 is a hexagonal recess, and the fastening tool is a hexagonal wrench. The hexagonal wrench is connected with the mounting component 133 through the first hole 111, and the hexagonal wrench is rotated to drive the first connecting piece 130 to move downward.

[0150] In some embodiments, the mounting component 133 can also be other polygonal recesses, and a wrench matched with the mounting component 133 can be used to fasten the first connecting piece 130.

[0151] In some embodiments, the mounting component 133 can also be other polygonal protrusions.

[0152] In the embodiments of the present application, the mounting component 133 is added to the first part 131, and a hexagonal wrench is used to connect with the mounting component 133 to fasten the first connecting piece 130, which simplifies the assembly process of the first connecting piece 130 and facilitates disassembly.

[0153] For example, when there is a small distance between the first part 131 and the first sub-hole 1121, only a slight rotation of the hexagonal wrench is needed to tighten the first connecting piece 130.

[0154] The embodiments of the third aspect of the present application provide a connection method of the connection structure of the above-mentioned embodiments, Figure 12 The flowchart of the connection method provided by some embodiments of the present application is shown in Figure 12 , and the method comprises the following steps.

[0155] In step S101, the first connecting piece is placed by the mounting structure, so that the first part of the first connecting piece is located in the second hole of the first mounting seat, and the second part of the first connecting piece passes through the second hole and is connected with the fourth hole of the second mounting seat.

[0156] In step S102, the first connecting piece is fastened by the first hole of the first mounting seat, so that the first connecting piece connects the first mounting seat and the second mounting seat.

[0157] By using the connecting method of the connecting structure 100 of the embodiments of the present application, the first connecting piece 130 is placed in the second hole 112 and the fourth hole 121, the first part 131 of the first connecting piece 130 is located in the second hole 112, the first connecting piece 130 is fastened by the fastening tool passing through the first hole 111, and the first mounting seat 110 and the second mounting seat 120 are fastened and connected by using the first connecting piece 130.

[0158] It should be understood that the first connecting piece 130 can be placed in the second hole 112 and the fourth hole 121 in different ways, so that the first part 131 of the first connecting piece 130 is located in the second hole 112, and the second part 132 of the first connecting piece 130 is connected with the fourth hole 121 through the second hole 112.

In some embodiments, the fastening method of the first connecting piece 130 can be rotating the fastening tool to drive the first connecting piece 130 to move in the depth direction (for example, the Z direction), so as to achieve the fastening of the first connecting piece 130. In some embodiments, the fastening method of the first connecting piece 130 can be driving the fastening tool to move in the depth direction (for example, the Z direction), and driving the first connecting piece 130 to move in the depth direction (for example, the Z direction), so as to achieve the fastening of the first connecting piece 130.

[0160] In the embodiments of the present application, the first connecting piece 130 is placed by the mounting structure, so that the first part 131 of the first connecting piece 130 is located in the second hole 112, and the second part 132 of the first connecting piece 130 is connected with the fourth hole 121 through the second hole 112, and then the first connecting piece 130 is fastened by the first hole 111, so that the first connecting piece 130 connects the first mounting seat 110 and the second mounting seat 120, which can solve the problem that the first connecting piece 130 protrudes from the first surface C1 and avoid scratching the product. At the same time, the assembly process of the first connecting piece 130 is simplified, and the disassembly is facilitated.

[0161] Referring to Figures 6 to 8 , in some embodiments, when the mounting structure is a third hole 113 penetrating the second surface C2, and the third hole 113 also penetrates at least one side surface of the first mounting seat 110, the side surface connects the first surface C1 and the second surface C2, Figure 13 A flowchart of step S101 provided by some embodiments of the present application is shown in Figure 13 , and step S101 includes:

[0162] Step S1011: Place the first connecting piece so that the second part of the first connecting piece is connected with the fourth hole of the second mounting seat.

[0163] Step S1012: Place the first mounting base through the third hole, so that the first part of the first connector passes through the third hole, passes through the side of the first mounting base, and enters the second hole.

[0164] For example, see Figure 1 , Figure 2 As shown, the first mounting base 110 also has a third hole 113, which is the portion of the second hole 112 extending toward the side of the first mounting base 110. One end of the third hole 113 is connected to the second hole 112, and the other end passes through at least one side of the first mounting base 110. In some embodiments, the third hole 113 passes through one side of the first mounting base 110. The third hole 113 serves as a mounting structure through which the first connector 130 passes. The first connector 130 can be inserted into the fourth hole 121 from the outside of the second mounting base 120, so that the second portion 132 of the first connector 130 is connected to the fourth hole 121. Then, with the side of the first mounting base 110 with the third hole 113 facing upward, the first mounting base 110 is moved in a direction perpendicular to the depth, so that the first portion 131 of the first connector 130 passes through the third hole 113 and is engaged in the second hole 112. At this time, the first part 131 of the first connector 130 is located in the second hole 112, and the second part 132 of the first connector 130 is located in the second hole 112 and the fourth hole 121. The first connector 130 can be fastened by passing a fastening tool through the first hole 111, and the first mounting base 110 and the second mounting base 120 can be fastened together by the first connector 130.

[0165] See Figures 6 to 8 The first mounting base 110 has two spaced-apart first holes 111, and two corresponding second holes 112 and a third hole 113. The first end of the third hole 113 communicates with the second hole 112, and the other end penetrates the second surface C2 of the first mounting base 110. Since the two third holes 113 penetrate the same side of the first mounting base 110, the method of this embodiment can be used to simultaneously insert the two first connectors 130 through the two third holes 113, completing the assembly of the two first connectors 130 in one step, thus improving assembly efficiency.

[0166] In some embodiments, when the mounting structure is a third hole 113 penetrating the second surface C2, the third hole 113 communicates with the second hole 112 in a direction parallel to the first surface C1, and the depth of the third hole 113 is greater than or equal to the depth of the second hole 112, Figure 14 A flowchart of another step S101 provided for some embodiments of this application is shown below. Figure 14 As shown, step S101 includes:

[0167] Step S1013: Pass the first connector through the fourth hole and the third hole.

[0168] Step S1014: moving the second mount so that the fourth hole communicates with the second hole and the first part is located in the second hole.

[0169] In some embodiments, referring to Figures 8 to 10 , the third hole 113 penetrates the second surface C2 and communicates with the second hole 112 in a direction parallel to the first surface C1, the third hole 113 of the first mount 110 and the fourth hole 121 of the second mount 120 can be aligned so that the third hole 113 and the fourth hole 121 communicate, the first connecting piece 130 is put into the third hole 113, the first connecting piece 130 passes through the fourth hole 121 and the third hole 113, the second mount 120 is moved so that the third hole 113 communicates with the second hole 112 and the first part 131 is located in the second hole 112. At this time, the first part 131 of the first connecting piece 130 is located in the second hole 112, the second part 132 of the first connecting piece 130 is located in the second hole 112 and the fourth hole 121, the first connecting piece 130 can be fastened through the first hole 111 by a fastening tool, and the first mount 110 and the second mount 120 are fastened and connected by the first connecting piece 130.

[0170] Exemplarily, referring to Figures 9 to 11 , the first mount 110 has four third holes 113 arranged in a matrix. Since the four third holes 113 are arranged in a matrix and the distance between the four third holes 113 and the corresponding first hole 111 is equal, the four first connecting pieces 130 can be put into the fourth hole 121 of the second mount 120 by the method of the embodiments of the present application, the second mount 120 is moved so that the four second holes 112 are aligned with the four fourth holes 121 respectively, and the first connecting piece 130 is fastened through the first hole 111, so that the assembly of the four first connecting pieces 130 can be completed at one time, improving the assembly efficiency.
