[0035] Reference Figure 1 , an embodiment of the present application provides a connector that can be used to connect two components.

[0036] like Figure 1 As shown, the connecting member includes:

[0037] A connecting plate 1 is provided with a first through hole 11 and a second through hole 12, wherein the first through hole 11 is configured to cooperate with an assembly portion on a first component 2 on one side, and the second through hole 12 is configured to cooperate with an assembly portion on a second component 3 on the opposite side.

[0038] like Figure 1 As shown, the embodiment of the utility model is provided with a first through hole 11 and a second through hole 12 on the connecting plate 1, and the first through hole 11 and the second through hole 12 are both through holes on the connecting plate 1, that is, the first through hole 11 and the second through hole 12 respectively penetrate the connecting plate 1, and the first through hole 11 and the second through hole 12 are used to form cooperation with the assembly parts of two components respectively. Among them, the two components can be two cylinders, two motors or other components that need to be connected together.

[0039] For example, the first through hole 11 and the second through hole 12 can be threaded holes, that is, the first through hole 11 and the second through hole 12 are engraved with internal threads, and the first component 2 and the second component 3 are respectively provided with bolts (i.e., assembly parts), and the bolts can form threaded fit with the first through hole 11 and the second through hole 12, so as to achieve a fastened connection between the first component 2 and the second component 3, and also enhance the connection reliability of the connector. Alternatively, the first through hole 11 and the second through hole 12 can also be smooth through holes, and the assembly parts of the two components are both protrusions, and the first through hole 11 and the second through hole 12 respectively form a snap fit with the assembly parts of the two components.

[0040] In addition, according to the actual connection situation, the number of the first through holes 11 and the number of the second through holes 12 provided on the connecting plate 1 can be adjusted to further improve the connection reliability of the connecting piece.

[0041] Specifically, the embodiment of the utility model sets the first through hole 11 and the second through hole 12 as through holes on the connecting plate 1, so that the connection strength of each component can be ensured by using two through holes, and the connection reliability of the connecting piece is also improved. In order to ensure the connection effect, the connecting plate 1 usually has a certain thickness, and its thickness is adapted to the extension length of the assembly parts on the two components to be connected.

[0042] Optionally, the first through hole 11 is a threaded hole, and the first through hole 11 is configured to form a threaded fit with a bolt on the first component 2 on one side.

[0043] Specifically, the first through hole 11 can be a threaded hole, that is, an internal thread is engraved in the first through hole 11, and a bolt (that is, its assembly part) is correspondingly provided on the first component 2, and an external thread is provided on the bolt rod. The external thread and the internal thread form a threaded match to achieve a fastened connection of the first component 2, and also enhance the connection reliability of the connecting piece.

[0044] Similarly, the second through hole 12 can be a threaded hole, that is, an internal thread is engraved in the second through hole 12, and a bolt (that is, its assembly part) is correspondingly provided on the second component 3, and an external thread is provided on the bolt rod. The external thread and the internal thread form a threaded match to achieve a fastened connection of the second component 3, and also enhance the connection reliability of the connecting piece.

[0045] Optionally, the shape of the second through hole 12 is the same as that of the first through hole 11 .

[0046] Specifically, the shape of the second through hole 12 in the embodiment of the utility model is the same as the shape of the first through hole 11. On the one hand, it is convenient to open the first through hole 11 and the second through hole 12 on the connecting plate 1 without replacing processing tools, thereby improving the processing efficiency of the connecting piece; on the other hand, setting the two through holes to have the same shape is also convenient for connecting two components with the same assembly part or two components of the same type, thereby improving the assembly efficiency of the driving mechanism using the connecting piece.

[0047] Optionally, at least one of the first through hole 11 and the second through hole 12 has a hole diameter of not less than 5 mm.

[0048] Specifically, according to the actual assembly size of the components to be connected, the aperture of the first through hole 11 can be set to be not less than 5 mm, the aperture of the second through hole 12 can be set to be not less than 5 mm, or the aperture of both the first through hole 11 and the second through hole 12 can be set to be not less than 5 mm. This makes it easier for the first through hole 11 and / or the second through hole 12 to adapt to bolts or other assembly parts of M5 or larger sizes, and can also improve the connection strength and shear resistance of the connection between the components and the connector, further enhancing the connection reliability of the connector.

[0049] Optionally, the first through hole 11 and the second through hole 12 are staggered.

[0050] Specifically, the embodiment of the utility model arranges the first through hole 11 and the second through hole 12 to be staggered, that is, the first through hole 11 and the second through hole 12 are not adjacent to each other, and the two components on both sides can be connected respectively by using the first through hole 11 and the second through hole 12 to ensure that the connection has a certain connection length, thereby ensuring the connection reliability of the connecting piece, and also making a certain distance between the first through hole 11 and the second through hole 12, further improving the connection strength of the connecting piece.

[0051] Optionally, a plurality of the first through holes 11 are formed on the connecting plate 1 , and the plurality of the first through holes 11 are arranged side by side.

[0052] like Figure 1As shown, according to the arrangement of the multiple assembly parts on the actual first component 2, multiple first through holes 11 can be arranged evenly or unevenly. For example, when multiple assembly parts on the first component 2 are evenly arranged side by side, multiple first through holes 11 can be arranged evenly side by side, and the multiple first through holes 11 match the multiple assembly parts on the first component 2 one by one, and the number of first through holes 11 on the connecting plate 1 matches the number of assembly parts on the first component 2, so as to enhance the connection strength and connection reliability between the connecting plate 1 and the first component 2. When multiple assembly parts on the first component 2 are unevenly arranged side by side, multiple first through holes 11 can also be arranged unevenly side by side, and the multiple first through holes 11 match the multiple assembly parts on the first component 2 one by one, so as to adapt to different component connection requirements.

[0053] Similarly, a plurality of second through holes 12 may be provided on the connection plate 1 , and the plurality of second through holes 12 may be arranged side by side, so that the connection strength of the connection plate can be enhanced by utilizing the plurality of first through holes 11 and second through holes 12 .

[0054] Optionally, the number of the second through holes 12 is the same as the number of the first through holes 11 .

[0055] Specifically, the embodiment of the utility model sets the number of second through holes 12 on the connecting plate 1 to be the same as the number of first through holes 11. On the one hand, it is convenient to open the first through holes 11 and the second through holes 12 on the connecting plate 1, thereby improving the processing efficiency of the connecting piece. On the other hand, setting the same number of two through holes also facilitates the connection of two components with the same assembly part, thereby improving the assembly efficiency of the driving structure using the connecting piece and further enhancing the connection reliability of the connecting piece.

[0056] Optionally, the connecting plate 1 is in a rectangular structure, and the plurality of the first through holes 11 and the plurality of the second through holes 12 are arranged side by side along the length direction of the connecting plate 1 .

[0057] Specifically, the embodiment of the utility model sets the connecting plate 1 to be a rectangular structure, that is, the connecting plate 1 is a rectangular plate, which can facilitate the processing and forming of the connecting plate 1. In addition, a plurality of first through holes 11 and a plurality of second through holes 12 are arranged side by side along the length direction of the connecting plate 1, respectively, and the first through holes 11 and the second through holes 12 can be used to respectively connect the two components on both sides, further strengthening the connection strength and connection reliability of the connection between the two components on both sides and the connecting plate 1, and at the same time, the length direction space of the connecting plate 1 can be fully utilized, reducing the influence of the hole opening process on the strength of the connecting plate 1.

[0058] Optionally, the distance between two adjacent first through holes 11 ranges from 8 mm to 15 mm.

[0059] Specifically, the spacing between two adjacent first through holes 11 in the embodiment of the utility model is set to be 8 mm to 15 mm, which can adapt to the assembly arrangement of most components, thereby facilitating the assembly of components and expanding the application range of the connector. In addition, the spacing also facilitates the opening of the first through holes 11 on the connecting plate 1, reduces the processing difficulty of the connecting piece, and also ensures the strength of the connecting plate 1 itself.

[0060] Similarly, the spacing between two adjacent second through holes 12 can be set to a range of 8 mm to 15 mm, which can adapt to the assembly arrangement of most components, thereby facilitating the assembly of components and expanding the adaptability of the connector. In addition, the spacing also facilitates the opening of the second through holes 12 on the connecting plate 1, reduces the processing difficulty of the connecting member, and also ensures the strength of the connecting plate 1 itself.

[0061] Optionally, along the width direction of the connecting plate 1 , the first through hole 11 and the second through hole 12 are located opposite to each other.

[0062] like Figure 1 As shown, the first through hole 11 and the second through hole 12 are positioned opposite to each other along the width direction of the connecting plate 1, that is, the first through hole 11 and the second through hole 12 are arranged longitudinally, so that the first through hole 11 and the second through hole 12 can be used to connect two components at opposite sides respectively, thereby reducing the difficulty of assembling the driving structure using the connecting piece.

[0063] The plurality of first through holes 11 and the plurality of second through holes 12 are evenly arranged along the length direction of the connecting plate 1 , and the first through holes 11 and the second through holes 12 are arranged longitudinally to form two regular rows of through hole structures, thereby improving the overall aesthetics of the connecting plate 1 .

[0064] Optionally, along the width direction of the connecting plate 1 , the first through hole 11 and the second through hole 12 are staggered in position.

[0065] Specifically, the first through hole 11 and the second through hole 12 of the embodiment of the utility model can also be staggered along the width direction of the connecting plate 1, that is, the first through hole 11 and the second through hole 12 are slightly offset longitudinally, and the first through hole 11 and the second through hole 12 can also be used to connect the two components on both sides respectively, thereby reducing the difficulty of assembling the driving mechanism using the connecting piece, and also facilitating the connection and fixing of different types of components, thereby expanding the scope of application of the connecting piece.

[0066] Optionally, a first positioning portion 13 and a second positioning portion are respectively provided on both sides of the connecting plate 1, wherein the first positioning portion 13 is configured to position the first component 2 on one side, and the second positioning portion is configured to position the second component 3 on the opposite side.

[0067] like Figure 1As shown, the first positioning portion 13 and the second positioning portion can be positioning protrusions, and the first component 2 and the second component 3 have grooves accordingly. The positioning protrusions cooperate with the grooves to form the positioning of the first component 2 and the second component 3, which is convenient for the reliable penetration of the assembly parts on the two components, thereby improving the installation accuracy of the connector.

[0068] In other embodiments, the first positioning portion 13 and the second positioning portion may be positioning grooves, and the first component 2 and the second component 3 may have protrusions respectively, and the positioning grooves cooperate with the protrusions to form positioning for the first component 2 and the second component 3 .

[0069] An embodiment of the present application also provides a driving structure, including a first component 2, a second component 3 and the above-mentioned connecting member, wherein the first component 2 cooperates with the first through hole 11 from one side of the connecting plate 1, and the second component 3 cooperates with the second through hole 12 from the other side of the connecting plate 1.

[0070] like Figure 1 As shown, the first through hole 11 and the second through hole 12 are usually threaded holes, that is, the first through hole 11 and the second through hole 12 are engraved with internal threads, and the first component 2 and the second component 3 are respectively provided with bolts, which can be penetrated into the first through hole 11 and the second through hole 12 and form a threaded fit, thereby achieving a fastened connection between the first component 2 and the second component 3, and also enhancing the structural reliability of the driving structure.

[0071] like Figure 2 As shown, the embodiment of the present application further provides a battery cell pressing mechanism, including the above-mentioned connecting member or the above-mentioned driving structure, wherein the first component 2 is a first cylinder, and the second component 3 is a second cylinder. The first cylinder cooperates with the first through hole 11 from one side of the connecting plate 1, and the second cylinder cooperates with the second through hole 12 from the other side of the connecting plate 1. The two cylinders on both sides can be connected by using the first through hole 11 and the second through hole 12 respectively to ensure that the connection has a certain connection length, thereby ensuring the structural reliability and safety of the battery cell pressing mechanism.
