[0055] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0056] As shown in the drawings, Figures 1-20 The present application provides a connecting assembly for connecting a first module 100 and a second module 200, which comprises a locking structure 1 and a holding structure 2. Wherein, the first module 100 and the second module 200 are adjacent, such as, the first module 100 and the second module 200 are stacked up and down, or the first module 100 and the second module 200 are abutted left and right. The connecting assembly can be applied to a container, such as a tool box, a tool box, a storage box, a storage basket, a drawer box, a roller box, a tool bag, etc. The connecting assembly can also be applied to a rigid platform, such as a flat car, an external hanging plate, a switching plate, a workbench, a drawing board, etc. The connecting assembly is mainly used for interlocking between two modules; the first module 100 can be a container, and the second module 200 can also be a container, and the connecting assembly interlocks the container with the container; the first module 100 / second module 200 can be a container, and the second module 200 / first module 100 can be a rigid platform, and the connecting assembly interlocks the container with the rigid platform; the first module 100 can be a rigid platform, and the second module 200 can also be a rigid platform, and the connecting assembly interlocks the rigid platform with the rigid platform.

[0057] The present application takes the first module 100 and the second module 200 as an example to illustrate the stacking of the first module 100 and the second module 200.

[0058] The locking structure 1 is arranged on the adjacent first module 100 and second module 200, for example, the locking structure 1 is arranged on the abutting surface of the first module 100 and the second module 200, or the position where the side of the first module 100 and the second module 200 is close to each other. The locking structure 1 has a locking state and an unlocking state, and the locking structure 1 can be switched between the locking state and the unlocking state through the action of the locking structure 1 itself. When the locking structure 1 is in the locking state, the adjacent first module 100 and second module 200 can be connected together to prevent the first module 100 and the second module 200 from being separated. When the locking structure 1 is in the unlocking state, the connection between the adjacent first module 100 and second module 200 can be cancelled to allow the first module 100 and the second module 200 to be separated. Moreover, the locking structure 1 can automatically remain in the locking state, and when the locking structure 1 is not under force, the locking structure 1 can automatically act in the locking direction to switch the locking structure 1 from the unlocking state to the locking state, thereby realizing the automatic locking of the first module 100 and the second module 200 by the locking structure 1.

[0059] In a preferred scheme, the locking structure 1 comprises a locking piece 11 and a locking groove 12, the locking groove 12 is arranged on the first module 100, and the locking piece 11 is arranged on the second module 200. For example, when the first module 100 and the second module 200 are docked, the locking piece 11 and the locking groove 12 are located at the side position of the first module 100 and the second module 200, so as to facilitate the locking and unlocking. Moreover, the locking piece 11 can act relative to the second module 200 (the action can be set as rotation or sliding, that is, the locking piece 11 is rotationally connected or slidingly connected on the second module 200), so that the locking piece 11 can extend into and out of the locking groove 12. When the locking structure 1 is in the locking state, the locking piece 11 extends into the locking groove 12, and when the locking structure 1 is in the unlocking state, the locking piece 11 extends out of the locking groove 12. By extending the locking piece 11 into and out of the locking groove 12, the switching of the locking structure 1 between the unlocking state and the locking state is realized. Specifically, a plurality of connecting assemblies can be arranged on the first module 100 and the second module 200, and the plurality of connecting assemblies are located at least at two opposite side positions of the docked first module 100 and second module 200, so as to realize the connection of the first module 100 and the second module 200 in different directions.

[0060] Moreover, the lock catch structure 1 further comprises a first elastic member 13, which is connected between the locking member 11 and the second module 200 and can drive the locking member 11 to act relative to the second module 200, so as to drive the locking member 11 to interfere with the locking slot 12 (i.e. the locking member 11 extends into the locking slot 12), and further to automatically keep the lock catch structure 1 in the locked state. When the first module 100 is connected with the second module 200 and the lock catch structure 1 is in the locked state, the first module 100 presses against the locking member 11, so as to align the locking member 11 with the locking slot 12, and thus the locking member 11 is automatically locked with the locking slot 12 under the action of the first elastic member 13.

[0061] The holding structure 2 comprises a first hinged member 201 and a second hinged member 202, a first end of the first hinged member 201 is hinged with a first end of the second hinged member 202 through a first hinged shaft 2021, a second end of the first hinged member 201 is hinged with the second module 200 through a second hinged shaft 2022, and a second end of the second hinged member 202 is hinged with the lock catch structure 1 through a third hinged shaft 2023, for example, the second end of the second hinged member 202 is hinged with the locking member 11 through the third hinged shaft 2023, so that through the relative rotation of the first hinged member 201 and the second hinged member 202, the second end of the first hinged member 201 and the second end of the second hinged member 202 can be close to and away from each other, and further the relative position of the locking member 11 and the second module 200 is changed, the locking member 11 is driven to act relative to the second module 200, the locking member 11 extends into and out of the locking slot 12, and further the locking and unlocking of the lock catch structure 1 is realized.

[0062] In the process that the first hinged member 201 and the second hinged member 202 act relative to the second module 200, the position of the second end of the first hinged member 201 relative to the second module 200 is fixed, and the first end and the second end of the second hinged member 202 act relative to the second module 200, when the height of the first end of the first hinged member 201 is not lower than the second end of the first hinged member 201, that is, when the height of the first end of the first hinged member 201 is not lower than the line connecting the second end of the first hinged member 201 and the second end of the second hinged member 202, the locking member 11 extends out of the locking slot 12, and through the linkage structure formed by the first hinged member 201 and the second hinged member 202, the lock catch structure 1 is kept in the unlocked state. In this way, the first module 100 and the second module 200 can be separated without applying a holding force to the lock catch structure 1, which is simple in operation and saves time and effort.

[0063] In the preferred solution, the retaining structure 2 further comprises a block 206 arranged on the second module 200, and when the locking structure is in the unlocked state, the height of the block 206 is not lower than the height of the second end of the first hinge 201 and the second end of the second hinge 202, so that the block 206 is in the movement path of the first hinge 201 / second hinge 202. During the process of switching the locking structure 1 from the locked state to the unlocked state, the first hinge 201 / second hinge 202 can move to abut against the block 206, and then the first end of the first hinge 201 / second hinge 202 is lifted relative to the second end, so that the height of the first end of the first hinge 201 is not lower than the second end. In this embodiment, the first end of the first hinge 201 can be lifted over the line connecting the second end of the first hinge 201 and the second end of the second hinge 202 by arranging the block 206.

[0064] In the specific solution, as shown in Figure 5 The first hinge 201 is provided with a limiting part 2012 that can rotate with the first hinge 201. The second module 200 is provided with a limiting part 207 that is in the movement path of the limiting part 2012 of the first hinge 201. During the process of switching the locking structure 1 from the locked state to the unlocked state, the locking structure 1 drives the second hinge 202 to act, and when the two ends of the first hinge 201 and the two ends of the second hinge 202 are in the same straight line, i.e., the first hinge shaft 2021, the second hinge shaft 2022, and the third hinge shaft 2023 are in the same plane, the block 206 abuts against the second hinge 202, the locking structure 1 drives the second hinge 202 to continue to act, and the block 206 can act as the fulcrum of the second hinge 202, so that the first end of the first hinge 201 is lifted over the line connecting the second end of the first hinge 201 and the second end of the second hinge 202, i.e., the first hinge shaft 2021 is lifted over the plane where the second hinge shaft 2022 and the third hinge shaft 2023 are located, to form a dead point position through the first hinge shaft 2021, the second hinge shaft 2022, and the third hinge shaft 2023, and at this time, the limiting part 207 blocks the limiting part 2012 from continuing to move, and then limits the first hinge 201 and the second hinge 202 at the position over the dead point. In this way, the locking structure 1 can be kept in the unlocked position, i.e., it cannot automatically return to the original position under the automatic locking action of the locking structure 1, and pressure must be applied to the first hinge 201 and the second hinge 202 to make the first hinge shaft 2021 downwardly pass through the plane where the second hinge shaft 2022 and the third hinge shaft 2023 are located (the dead point position of the first hinge 201 and the second hinge 202), and return to the locked state.

[0065] In some preferred embodiments, the first hinge 201 / second hinge 202 is provided with a trigger 2011, which can act with the first hinge 201 / second hinge 202, i.e. the trigger 2011 can act with the lock structure 1. In the present embodiment, the trigger 2011 is fixedly connected with the first hinge 201, or the trigger 2011 is integrally formed with the first hinge 201. Moreover, the trigger 2011 protrudes from the second module 200 in a direction close to the first module 100, so that the first module 100 first presses against the trigger 2011 and then presses against the second module 200. In this way, when the lock structure 1 is in the unlocked state and the two modules are close to each other, the first module 100 first presses against the trigger 2011, and the first module 100 drives the trigger 2011 to act relative to the second module 200 (since the trigger 2011 is arranged on the first hinge 201, and the second end of the first hinge 201 is hinged to the second module 200, the action is that the trigger 2011 rotates with the first hinge 201 relative to the second module 200), thereby causing the first hinge 201 and the second hinge 202 to rotate relative to each other, and thereby causing the first end of the first hinge 201 to be lower than the second end of the first hinge 201 (i.e. the first end of the first hinge 201 passes over the line connecting the second end of the first hinge 201 and the second end of the second hinge 202 downwardly), and the distance between the second end of the first hinge 201 and the second end of the second hinge 202 is reduced, thereby achieving the switching of the lock structure 1 from the unlocked state to the locked state.

[0066] As shown in Figures 7-9 the trigger 2011 is arranged on the side of the first hinge 201 close to the first module 100, and when the lock structure 1 is in the unlocked state, the trigger 2011 is located on the side of the second end of the first hinge 201 close to the second hinge 202. In this way, when the first module 100 and the second module 200 are close to each other, the first module 100 presses against the trigger 2011, thereby driving the trigger 2011 and the first end of the first hinge 201 to displace in a direction close to the second module 200, which is beneficial to save the occupied space of the retaining structure 2. Moreover, in the process of the first module 100 driving the trigger 2011 (relative to the first end of the first module 100) to be close to the second module 200, the second end of the first hinge 201 and the second end of the second hinge 202 are close to each other, so as to achieve the folding of the first hinge 201 and the second hinge 202, thereby compressing the occupied size of the retaining structure 2, which is beneficial to improve the compactness of the structure.

[0067] In some embodiments, the retaining structure 2 further includes an abutment 203 and a second elastic member 204. The abutment 203 is connected to the first module 100 and can move relative to the first module 100. For example, the connection between the abutment 203 and the first module 100 is a sliding connection or a rotational connection. The second elastic member 204 is disposed between the abutment 203 and the first module 100. The second elastic member 204 can drive the abutment 203 from a first position to a second position, so that the movement of the abutment 203 between the first and second positions completes the linkage with the trigger part 2011. Specifically, the second position is closer to the locking structure 1 relative to the first position, so that the abutment 203 can link with the trigger part 2011 in the second position. Specifically, when the abutment 203 is in the first position, the abutment 203 and the second elastic member 204 are in a compressed state; when the abutment 203 is in the second position, the abutment 203 and the second elastic member 204 are in an extended state.

[0068] like Figures 7-9 As shown in Figures 13-15, when the latching structure 1 is in the unlocked state and the two modules are close together, under the action of the second elastic member 204, the abutment member 203 is in the second position and abuts against the trigger part 2011, so as to drive the trigger part 2011 to move forward (here, the forward movement is distinguished from the reverse movement; the forward movement means that the trigger part 2011 moves closer to the second module 200 relative to the second end of the first hinge member 201, and the reverse movement means that the trigger part 2011 moves away from the second module 200 relative to the second end of the first hinge member 201), thereby causing the latching structure 1 to switch from the unlocked state to the locked state; when the latching structure 1 is in the unlocked state and the two modules are separated, the second elastic member 204 of the abutment member 203 is in the compressed state under the action of the trigger part 2011. At this time, the holding force of the retaining structure 2 in keeping the latching structure 1 in the unlocked state is greater than the elastic force of the second elastic member 204. When the two modules are completely separated, the latching structure 1 is still in the unlocked state. In other words, when the two modules are connected and separated, the retaining structure 2 can keep the locking structure 1 in the unlocked state, which is conducive to the connection and separation of the two modules.

[0069] It can be understood that when the lock catch structure 1 is switched from the locking state to the unlocking state, the lock catch structure 1 (i.e. the locking piece 11) drives the first and second hinge pieces 201 and 202 to rotate relatively, so that the trigger part 2011 reversely acts, and at the same time, the trigger part 2011 abuts against the abutting piece 203 and drives the abutting piece 203 to move from the second position to the first position, at this time, the second elastic piece 204 of the abutting piece 203 is in a compressed state under the action of the trigger part 2011. In this way, through the arrangement of the abutting piece 203, the action stroke of the trigger part 2011 can be converted into the action stroke of the abutting piece 203 and the elastic potential energy of the second elastic piece 204 during the unlocking process of the lock catch structure 1, and the force driving the first module 100 away from the second module 200 cannot be generated, and thus the first module 100 and the second module 200 can be kept in abutment during the unlocking and locking processes, which is beneficial to improving the connection stability and reliability.

[0070] The abutting piece 203 has a first abutting surface 2032 and a second abutting surface 2033, the first abutting surface 2032 is located on the side of the abutting piece 203 close to the second module 200, and the second abutting surface 2033 is located on the side of the abutting piece 203 close to the lock catch structure 1, and the first and second abutting surfaces 2032 and 2033 are respectively used for abutting cooperation with the trigger part 2011. When the lock catch structure 1 is in the unlocking state and the two modules are close, the trigger part 2011 abuts against the first abutting surface 2032, the trigger part 2011 positively acts and at the same time slides along the first abutting surface 2032, until the trigger part 2011 passes the first abutting surface 2032 in the direction close to the lock catch structure 1, at this time, the lock catch structure 1 is in the locking state. When the lock catch structure 1 is switched from the locking state to the unlocking state, the trigger part 2011 abuts against the second abutting surface 2033, the trigger part 2011 reversely acts and at the same time drives the abutting piece 203 to move from the second position to the first position, so that the abutting piece 203 and the second elastic piece 204 are in a compressed state. In this way, through the arrangement of the first and second abutting surfaces 2032 and 2033, the trigger part 2011 can drive the abutting piece 203 to act, and the abutting piece 203 can drive the trigger part 2011 to act, so as to convert the action stroke of the trigger part 2011 into the elastic potential energy of the second elastic piece 204, which is simple in structure and stable and reliable.

[0071] The first and second abutting surfaces 2032 and 2033 are perpendicular, so that during the abutting cooperation between the trigger part 2011 and the abutting piece 203, the trigger part 2011 can be switched between the first and second abutting surfaces, and the first and second abutting surfaces 2032 and 2033 are perpendicular to the force direction of the abutting piece 203 and the trigger part 2011, which is beneficial to ensuring the stability of the abutting movement.

[0072] In addition, other structures may be provided on the abutment 203 to allow the trigger 2011 to slide on the first abutment surface 2032 of the abutment 203 in a direction close to the locking structure 1, and to prevent the trigger 2011 from sliding on the first abutment surface 2032 of the abutment 203 in a direction away from the locking structure 1.

[0073] The following describes in detail several implementation schemes of the abutment member 203 with reference to the accompanying drawings.

[0074] like Figures 7-9 As shown in Figures 13-15, the first module 100 is provided with a strip-shaped mounting groove. The extension direction of the mounting groove is perpendicular to the arrangement direction of the first module 100 and the second module 200, and parallel to the direction approaching and away from the locking structure 1. The abutment 203 is limited within the mounting groove and can slide along the extension direction of the mounting groove. The second elastic member 204 is configured as a compression spring and abuts against the abutment 203 and the first groove wall of the mounting groove, for driving the abutment 203 to slide along the mounting groove from the first position to the second position. When the abutment 203 is in the second position, it abuts against the second groove wall of the mounting groove. At the same time, the abutment 203 protrudes from the second groove wall of the mounting groove, or the second groove wall does not exist and forms an opening for the abutment 203 to extend into and out of the mounting groove, so that the trigger part 2011 can push the abutment 203 to slide from the second position to the first position at the second groove wall of the mounting groove.

[0075] like Figure 18 , 19 As shown, a mounting base 205 is provided on the first module 100, and a mounting groove is provided on the mounting base 205. The opening of the mounting groove faces the locking structure 1 (i.e., away from the first module 100). The first end of the abutment 203 is rotatably connected to the mounting groove through a first rotating shaft 2031, and the abutment 203 rotates around the first rotating shaft 2031 at a set angle. The axis of the first rotating shaft 2031 is parallel to the arrangement direction of the first module 100 and the second module 200, and the second end of the abutment 203 is located outside the mounting groove and moves in the direction of approaching and moving away from the mounting groove. Specifically, when the second end of the abutment 203 moves in the direction close to the locking structure 1, that is, when the second end of the abutment 203 moves in the direction away from the first module 100, the second elastic member 204 drives the abutment 203 from a compressed state to an extended state; when the second end of the abutment 203 moves in the direction away from the locking structure 1, that is, when the second end of the abutment 203 moves in the direction close to the first module 100, the abutment 203 moves from an extended state to a compressed state.

[0076] In some preferred embodiments, the second elastic member 204 is a torsion spring, and the second elastic member 204 can also be a spring sheet. The second elastic member 204 is connected between the mounting seat 205 and the abutting member 203, and is used to drive the abutting member 203 to move from the first position to the second position.

[0077] As shown in Figure 20 The first module 100 is provided with a mounting seat 205, and the mounting seat 205 is provided with a mounting groove. The opening direction of the mounting groove is towards the second module 200. The first end of the abutting member 203 is rotationally connected to the bottom of the mounting groove through a first rotating shaft 2031. The axial direction of the first rotating shaft 2031 is perpendicular to the arrangement direction of the first module 100 and the second module 200. The second end of the abutting member 203 is located outside the mounting groove and moves towards and away from the mounting groove. For example, the second elastic member 204 is a compression spring and is connected between the abutting member 203 and the first groove wall of the mounting groove, and is used to drive the abutting member 203 to move from the first position to the second position. When the abutting member 203 is in the second position, it abuts against the second groove wall of the mounting groove. The first groove wall of the mounting groove is away from the lock catch structure 1 relative to the second groove wall, and the abutting member 203 protrudes from the second groove wall of the mounting groove, so that the trigger portion 2011 can push the abutting member 203 to slide from the second position to the first position at the second groove wall of the mounting groove.

[0078] In some embodiments, the second module 200 is provided with a base 6 to bear other components. In order to ensure the structural reliability and facilitate subsequent assembly, the other components are assembled on the base 6 and then mounted on the corresponding second module 200, so that the connection assembly forms a standardized interface assembly. Only the assembly position needs to be reserved on the second module 200, and the connection assembly can be assembled when needed to realize the corresponding connection function. Specifically, the second end of the first hinge member 201 is hingedly connected to the base 6 through a second hinge shaft 2022 to realize the hinge connection relative to the second module 200. The locking member 11 is connected to the base 6 and can move relative to the base 6 to realize the connection of the locking member 11 relative to the second module 200.

[0079] The lock catch structure 1 includes a locking member 11, a locking groove 12, and a first elastic member 13. The locking groove 12 is arranged on the first module 100, the locking member 11 is arranged on the base 6, and the first elastic member 13 is connected between the locking member 11 and the base 6 and can drive the locking member 11 to move relative to the base 6, so that the lock catch structure 1 is switched from the unlocked state to the locked state.

[0080] The various connection modes of the locking member 11 will be described in detail below with reference to the accompanying drawings.

[0081] As shown in Figures 3-9As shown, the lock catch structure 1 is arranged as a rotary lock catch, the locking piece 11 is rotatably connected to the base 6 (i.e. the second module 200) through a second rotating shaft 14, and the axis of the second rotating shaft 14 is different from the axis of the second hinge 202 relative to the hinge axis of the locking piece 11, i.e. the second rotating shaft 14 is different from the third hinge axis 2023, so that when the locking piece 11 rotates relative to the base 6, the second hinge 202 and the first hinge 201 can be driven to act relative to the base 6 (i.e. the second module 200). The first elastic piece 13 can drive the locking piece 11 to rotate in the direction close to the locking slot 12, so as to keep the locking piece 11 extending into the locking slot 12, and improve the stability of the locking. Wherein, the first elastic piece 13 is arranged as a torsion spring, and is sleeved outside the second rotating shaft 14, one end of the torsion spring is connected with the base 6, and the other end is connected with the locking piece 11.

[0082] As shown in the first embodiment, Figures 10-20 As shown, the lock catch structure 1 is arranged as a sliding lock catch, the locking piece 11 is slidably connected to the base 6 (i.e. the second module 200), and a plurality of sliding rails are arranged between the locking piece 11 and the base 6 to realize the sliding guidance of the locking piece 11 relative to the base 6. The first elastic piece 13 can drive the locking piece 11 to slide in the direction close to the locking slot 12, so as to keep the locking piece 11 extending into the locking slot 12, and improve the stability of the locking. Wherein, the first elastic piece 13 is arranged as a compression spring, and abuts between the locking piece 11 and the base 6.
