The following describes the implementation method of the present utility model based on its overall structure.

[0052] Reference Figure 1 As shown, the embodiment of the present application provides a plate connection structure, including:

[0053] A first panel 1 and a second panel 2 are arranged close to each other;

[0054] A first connecting member 3 is riveted on the first panel 1, and a mounting hole 21 is opened on the second panel 2;

[0055] The first connecting member 3 includes a support frame 31 and a retaining ring 32. The support frame 31 is fixedly connected between the first panel 1 and the second panel 2. The support frame 31 contacts the second panel 2. The support frame 31 has an inner cavity 311. The retaining ring 32 is installed on the wall of the inner cavity 311 close to the first panel 1.

[0056] A second connecting member 4 is inserted into the mounting hole 21, and the second connecting member 4 is inserted into the inner cavity 311 and riveted to the retaining ring 32;

[0057] Among them, an elastic member 5 is installed in the inner cavity of the support frame 31, and the two ends of the elastic member 5 respectively abut against the retaining ring 32 and the wall of the inner cavity 311, the mounting hole 21 includes a first hole 211 and a second hole 212 which are connected to each other, and the end of the second connecting member 4 away from the second panel 2 is fixedly connected with a baffle 41, the outer diameter of the baffle 41 is smaller than the outer diameter of the first hole 211, and the outer diameter of the baffle 41 is larger than the outer diameter of the second hole 212, the second panel 2 and the baffle 41 move relative to each other, so that the baffle 41 matches the second hole 212 to lock the second panel 2, or, the baffle 41 matches the first hole 211 to unlock the second panel 2.

[0058] according to Figure 1 , those skilled in the art can arrange the first panel 1 and the second panel 2 close to each other. The first connecting member 3 is arranged on the first panel 1, and the second connecting member is arranged on the second panel 2. Through the structure in which the first connecting member 3 and the second connecting member 4 are connected to each other, the first panel 1 and the second panel 2 can be stably connected.

[0059] Specifically, in the structure where the first panel 1 is connected to the first connector 3, the first connector 3 and the first panel 1 may be riveted. The first connector 3 includes a support frame 31 and a retaining ring 32, and the support frame 31 is disposed between the first panel 1 and the second panel 2. The support frame 31 is riveted to the first panel 1, thereby enabling the first connector 3 to be riveted to the first panel 1.

[0060] Regarding the support frame 31 being riveted to the first panel 1, it can be understood that the outer wall of one end of the support frame 31 is riveted to the first panel 1. The other end of the support frame 31 is disposed close to the second panel 2.

[0061] In the above-mentioned setting, the first connecting member 3 in this embodiment further includes a retaining ring 32. Those skilled in the art may set the retaining ring 32 in the inner cavity 311 of the support frame 31. Specifically, the retaining ring 32 may be set on the inner wall of the inner cavity 311 close to the first panel 2. It is understood that, in one embodiment, the inner cavity 311 has an opening toward the second panel 2. That is, the side of the inner cavity 311 toward the first panel 1 is closed. In turn, the retaining ring 32 may be moved in the inner cavity 311.

[0062] The second connecting member 4 is provided on the second panel 2. A person skilled in the art may provide a mounting hole 21 on the second panel 2, and the second connecting member 4 passes through the mounting hole 21. The end of the second connecting member 4 facing the second panel 2 is passed through the inner cavity 311 of the support frame 31, and the end of the second connecting member 4 facing the second panel 2 is riveted to the retaining ring 32.

[0063] In the above structure, the second connecting member 4 is inserted through the mounting hole 21. Those skilled in the art may set the mounting hole 31 so that the first hole 211 is connected to the second hole 212. A baffle 4 may be provided at the end of the second connecting member 4 away from the first panel 1. The outer diameter of the baffle 4 is smaller than the outer diameter of the first hole 211, and the outer diameter of the baffle 4 is larger than the outer diameter of the second hole 212.

[0064] With the above structure, when the second connecting member 4 is inserted out of the first hole 211 , the second panel 2 can be moved along the second connecting member 4 , thereby realizing the disassembly of the second panel 2 .

[0065] In the embodiment of the present application, the second panel 2 can be reciprocated along the direction of the line connecting the second hole 212 and the center position of the first hole 211. During the movement of the second panel 2, it can be moved until the second connecting member 4 is inserted into the second hole 212. The second connecting member 4 passes through the second hole 212 and is inserted into the inner cavity 311 of the support frame 31, and the side wall of the baffle 4 facing the second panel 2 contacts the second panel 2. The side wall of the support frame 31 facing the second panel 2 contacts the second panel 2. In this way, a stable connection between the first panel 1 and the second panel 2 can be achieved.

[0066] In the above structure, a person skilled in the art may also arrange an elastic member 5 connected to the inner cavity 311 of the support frame 31. The two ends of the elastic member 5 respectively contact the retaining ring 32 and the wall surface of the inner cavity 311. It is understandable that in the above structure, the second connecting member 4 passes through the mounting hole 21 and is riveted to the retaining ring 32. Preferably, the elastic member 5 may be arranged as a compression spring.

[0067] In the structure where the elastic member 5 is configured as a compression spring, the compression spring is sleeved on the outer wall of the second connecting member 4 located in the inner cavity 311, and one end of the compression spring abuts against the retaining ring 32, and the other end of the compression spring abuts against the wall of the inner cavity 311.

[0068] After the second panel 2 moves, the baffle 41 of the second connector 4 corresponds to the position of the second hole 212, so that the baffle 41 of the second connector 4 contacts the second panel 2. During the relative movement of the second connector 4 and the second panel 2, the second connector 4 moves in a direction away from the first panel 1 under the push of the second panel 2. Then, the retaining ring 32 can compress the compression spring, so that the compression spring generates a force to restore the deformation. Then, the second connector 4 can be pressed tightly.

[0069] In the above process, when the second connecting member 4 is inserted into the first hole 211, the baffle 41 of the second connecting member 4 is located in the first hole 211 toward the side wall of the first panel 1. In the process of the second connecting member 4 moving from the first hole 211 to the second hole 212, the baffle 41 of the second connecting member 4 moves toward the side wall of the first panel 1 to the side wall of the second panel 2 away from the first panel 1. In the above process, the second connecting member 4 is displaced to compress the elastic member 5.

[0070] In summary, the first panel 1 and the second panel 2 are connected by riveting the first connecting member 3 and the second connecting member 4, and the second connecting member 4 is inserted into the second hole 212. When the second connecting member 4 is inserted into the first hole 211, the connection between the first panel 1 and the second panel 2 is released.

[0071] In this embodiment, the second connector 4 passes through the mounting hole 21. Preferably, the side wall of the baffle plate 41 of the second connector 4 facing the second panel 2 is provided with a step portion 42, and the step portion 42 is provided in the mounting hole 21. It can be understood that the second connector 4 has a portion that matches the mounting hole 21. In this embodiment, those skilled in the art arrange that the matching portion is provided with a step portion 42.

[0072] With the above structure, the step portion 42 is installed in the mounting hole 21, that is, the maximum outer diameter of the step portion 42 is smaller than the minimum hole diameter of the mounting hole 21. When the second panel 2 moves, the step portion 42 switches between the states of matching with the first hole 211 and the second hole 212.

[0073] When the step portion 42 is matched with the first hole 211, the second panel 2 can be moved and taken out. When the step portion 42 is matched with the second hole 212, the two opposite sides of the second panel 2 respectively contact the support frame 31 and the baffle 41. Among them, the step portion 42 is in the first hole 211 or the second hole 212. Then, the first hole 211 and the second hole 212 can be blocked. It is prevented that debris enters the first hole 211 and the second hole 212.

[0074] In the setting of those skilled in the art, preferably, the second connector 4 and the retaining ring 32 are riveted to each other by press riveting or flip riveting. The press riveting or flip riveting connection can make the fixed connection between the second connector 4 and the retaining ring 32 permanent, thereby effectively improving the stability of the connection between the first panel 1 and the second panel 2.

[0075] In this embodiment, preferably, the first panel 1 and the support frame 31 are riveted to each other by press riveting or flip riveting. This can make the connection between the support frame 31 and the first panel 1 more stable. More preferably, the first panel 1 and the support frame 31 are riveted to each other by back press riveting or forward press riveting. This can enable those skilled in the art to complete the fixed connection between the first connector 3 and the first panel 1 in various situations.

[0076] In summary, those skilled in the art may adopt different connection methods to fix the first connection member 3 and the first panel 1 and the second connection member 4 and the retaining ring 32 in different situations.

[0077] In the arrangement of the second connecting member 4, preferably, the outer edge of the side wall of the baffle 41 facing the second panel 2 is set as an inclined surface. Therefore, the baffle 41 can slide to be pressed against the second panel 2 during the movement of the second panel 2.

[0078] In one embodiment, preferably, the outer edge of the side wall of the baffle 41 facing the second panel 2 is set to be a spherical surface. Therefore, the baffle 41 can slide to be pressed against the second panel 2 during the movement of the second panel 2.

[0079] During the installation of the first connecting member 3 and the second connecting member 4, preferably, the axis of the first connecting member 3 is in the same straight line as the axis of the second connecting member 4. Thus, the retaining ring 32 in the first connecting member 3 and the second connecting member 4 can be stably fixedly connected during the riveting process.

[0080] In the above process, those skilled in the art may pre-rivet the support frame 31 and the first panel 1. In the process of connecting the first panel 1 and the second panel 2, only the second connecting member 4 and the retaining ring 32 need to be riveted. That is, the connection between the first panel 1 and the second panel 2 can be completed by riveting once.

[0081] In one embodiment, preferably, the first panel 1 and the second panel 2 are parallel to each other. Thus, during the movement of the second panel 2, the first panel 1 and the second panel 2 can be stably connected, thereby avoiding the deformation of the first panel 1 or the second panel 2 during the compression of the elastic member 5.

[0082] In one embodiment, preferably, a plurality of mounting holes 21 are provided at intervals on the second panel 2 for installing the connection structure of the plurality of first connectors 3 and the second connectors 4. That is, the second panel 2 is provided with a plurality of mounting holes 21 so that it can be connected to the first panel 1 at multiple positions at the same time, thereby meeting various connection strength requirements.

[0083] Preferably, the first connecting member 3 is riveted on the first panel 1 to form an integrated structure for continuing to connect with the second panel 2. In this embodiment, those skilled in the art can rivet the first connecting member 3 on the first panel 1 before connecting the first panel 1 with the second panel 2. Then, in the process of connecting the first panel 1 with the second panel 2, only the second connecting member 4 and the retaining ring 32 need to be riveted to complete the connection between the first panel 1 and the second panel 2. That is, in this embodiment, only one riveting is required to connect the first panel 1 with the second panel 2. The efficiency of the operation is improved in terms of steps.

[0084] Preferably, the first connecting member 3 includes at least one retaining ring 32 , and the second connecting member 4 is inserted into the inner cavity and riveted to the retaining ring 32 away from the second panel 2 , so that the retaining ring 32 close to the second panel 2 shields the side wall of the support frame 31 close to the second panel 2 .

[0085] According to the above structure, those skilled in the art can arrange that the first connecting member 3 includes at least one retaining ring 32. That is, there are cases where one retaining ring 32 and multiple retaining rings 32 are arranged in the inner cavity 311 of the support frame 31. Among them, the embodiment of arranging one retaining ring 32 in the inner cavity 311 is described in the above embodiment.

[0086] In addition, when multiple retaining rings 32 are provided in the inner cavity 311, the second connecting member 4 can be inserted into the inner cavity 311 and riveted to the retaining ring 32 away from the second panel 2. Specifically, except for the retaining ring 32 away from the second panel 2, other retaining rings 32 can be set to be sleeved on the outer wall of the second connecting member 4.

[0087] By means of the above structure, after the second connecting member 4 moves, the first panel 1 is tightly connected to the second panel 2. The retaining ring close to the second panel 2 can contact and block the side wall of the support frame 31 close to the second panel 2. Thus, the inner cavity 311 in the support frame 31 can be effectively sealed.

[0088] In one embodiment, the structure using multiple retaining rings 32 can effectively prevent materials from entering the inner cavity 311 during the injection molding and bonding process, thereby preventing the second connecting member 4 from being blocked by debris, resulting in a connection failure between the first panel 1 and the second panel 2.

[0089] Furthermore, the outer diameters of the plurality of retaining rings 32 may be set to be different. It is worth noting that the outer diameter of the retaining ring 32 near the support frame 31 facing the second panel 2 is larger than the diameter of the hole for penetrating the second connecting member 4 on the support frame 31 facing the second panel 2.

[0090] Preferably, a cover plate 6 is provided on the side wall of the second panel 2 away from the first panel 1, and the cover plate 6 is used to magnetically attract the second connector 4. That is, in this embodiment, those skilled in the art can arrange that the cover plate 6 is attached to the side wall of the second panel 2 away from the first panel 1.

[0091] By means of the above structure, the cover plate 6 can shield and protect the structure connecting the first panel 1 and the second panel 2. Furthermore, those skilled in the art can arrange that the cover plate 6 can magnetically attract the second connector 4.

[0092] That is, when the cover plate 6 is installed, the second connector 4 can be magnetically attracted by the cover plate 6, so that the second connector 4 moves toward the position of the second panel 2. Then the second panel 2 is moved, so that the second connector 4 moves from the position of the first hole 211 to the position of the second hole 212, thereby completing the connection between the first panel 1 and the second panel 2. In the process of unlocking the first panel 1 and the second panel 2, the cover plate 6 can be magnetically attracted to the second connector 4, and then the second panel 2 is moved, so that the second connector 4 moves from the position of the second hole 212 to the position of the first hole 211.

[0093] In summary, the structure of connecting the first panel 1 and the second panel 2 described in the present application can satisfy but is not limited to the situations of press riveting, riveting, welding, injection molding, buckling and gluing. It can also realize the buried hidden connection function, and unlock by means of magnetic attraction / sliding fit.

[0094] Although different specific embodiments are mentioned in the content of this application, this application is not limited to the situations described in the industry standards or embodiments, etc. Some industry standards or slightly modified implementation plans based on the implementation of the custom methods or embodiments can also achieve the same, equivalent or similar, or predictable implementation effects after deformation of the above embodiments. The embodiments of data acquisition, processing, output, judgment methods, etc. after these modifications or deformations can still fall within the scope of the optional implementation plans of this application.

[0095] Although the present application has been described through embodiments, those skilled in the art will appreciate that there are many modifications and changes to the present application without departing from the spirit of the present application. It is intended that the attached embodiments include these modifications and changes without departing from the present application.
