[0039] According to one embodiment of this application, the connecting plate 112 includes a third pin seat 1122 spaced apart, the base plate 111 includes a fourth pin seat 1112 spaced apart, the fourth pin seat 1112 is disposed between adjacent spaced third pin seats 1122; the cup holder 11 also includes a second shaft pin 116, the second shaft pin 116 passes through the third pin seat 1122 and the fourth pin seat 1112.

[0040] In this embodiment of the application, the second pin 116 passes through the third pin seat 1122 and the fourth pin seat 1112, and the base plate 111 can rotate relative to the connecting plate 112 around the second pin 116 to realize the rotational connection between the base plate 111 and the connecting plate 112.

[0041] The above embodiments achieve the rotation of the base plate 111 relative to or away from the embedding groove 101 through the rotating shaft 1111, the rotational connection of the top plate 113 and the connecting plate 112 through the first shaft pin 115, the rotational connection of the base plate 111 and the connecting plate 112 through the second shaft pin 116, and the sliding of the pin 1132 in the sliding groove 1012 to move the top plate 113 away from or near the base plate 111, so as to achieve the sliding connection of the top plate 113 and the mounting base 10.

[0042] When the cup holder 11 is needed, the pin 1132 of the top plate 113 slides in the sliding groove 1012 toward the bottom plate 111. At this time, the top plate 113 rotates relative to the connecting plate 112, the connecting plate 112 rotates relative to the bottom plate 111, and the bottom plate 111 rotates outward toward the embedding groove 101 until the pin 1132 of the top plate 113 reaches the end of the sliding groove 1012 or until the bottom plate 111 rotates outward toward the embedding groove 101 and is in a horizontal state. The bottom plate 111, the connecting plate 112, and the top plate 113 form a cup holder structure. The bottom plate 111, the connecting plate 112, and the top plate 113 form a support structure for the cup holder structure, forming a receiving cavity 114 for accommodating the cup. The cup or other objects that need to be placed can enter the receiving cavity 114 from the overhead part 1131 on the top plate 113, so that the user can conveniently and quickly place the cup.

[0043] When the cup holder 11 is not needed, the pin 1132 of the top plate 113 slides away from the bottom plate 111 in the sliding groove 1012. At this time, the top plate 113 rotates relative to the connecting plate 112, the connecting plate 112 rotates relative to the bottom plate 111, and the bottom plate 111 rotates towards the interior of the embedding groove 101. When the pin 1132 of the top plate 113 reaches the end of the sliding groove 1012 away from the bottom plate 111, the top plate 113, the connecting plate 112, and the bottom plate 111 are fully unfolded and stored in the embedding groove 101. The cup holder 11 is flattened and hidden in the mounting base 10, achieving a hidden state and not occupying space.

[0044] According to one embodiment of this application, referring to Figure 1 and Figure 5 The top plate 113, away from the mounting base 10, includes a locking element 1135. The recessed groove 101 is correspondingly provided with a snap-fit ​​part 1013. The locking element 1135 cooperates with the snap-fit ​​part 1013 to lock the cup holder 11 when the bottom plate 111 is housed in the recessed groove 101.

[0045] In this embodiment, a locking member 1135 is provided on the top plate 113, and a snap-fit ​​part 1013 is provided in the mounting groove 101 corresponding to the position of the locking member 1135. When the cup holder 11 is not needed, the pin 1132 of the top plate 113 slides away from the bottom plate 111 in the sliding groove 1012. At this time, the top plate 113 rotates relative to the connecting plate 112, the connecting plate 112 rotates relative to the bottom plate 111, and the bottom plate 111 rotates towards the interior of the mounting groove 101. When the pin 1132 of the top plate 113 reaches the end of the sliding groove 1012 away from the bottom plate 111, the top plate 113, the connecting plate 112, and the bottom plate 111 are fully unfolded and stored in the mounting groove 101. The cup holder 11 is hidden in the mounting base 10. The locking member 1135 and the snap-fit ​​part 1013 cooperate to lock the top plate 113, that is, to lock the cup holder 11 and fix the cup holder 11 so as not to fall off.

[0046] According to one embodiment of this application, referring to Figure 3 and Figure 5 The locking element 1135 includes a pressing part 1135a and a locking part 1135b connected to each other. The locking part 1135b is used to engage with the locking part 1013. When the pressing part 1135a is disposed in the top plate 113 and housed in the recess 101, the top plate 113 is away from the plane of the mounting base 10. The locking part 1135b is disposed on the side of the top plate 113. When the pressing part 1135a moves into the recess 101, it can drive the locking part 1135b to disengage from the locking part 1013, thereby unlocking the cup holder 11.

[0047] In this embodiment, the pressing part 1135a of the locking member 1135 is located on the plane of the top plate 113 away from the mounting base 10 when the cup holder 11 is hidden in the mounting base 10. The locking part 1135b of the locking member 1135 is located on the side of the top plate 113 away from the connecting plate 112. The locking part 1135b engages with the locking part 1013 to lock the cup holder 11. By pressing the pressing part 1135a towards the side near the insert groove 101, the locking part 1135b can be disengaged from the locking part 1013 to unlock the cup holder 11. After unlocking, the cup holder 11 can be rotated and folded to form a cup holder structure as needed, allowing users to conveniently and quickly place the cup.

[0048] In some embodiments, the pressing part 1135a has a certain deformation capability. When the cup holder 11 is hidden in the mounting base 10, pressing the pressing part 1135a towards the side near the embedding groove 101 can disengage the locking part 1135b from the mounting base 10, thereby unlocking the cup holder 11. When the cup holder 11 is in the cup support structure, the pressing part 1135a is in a rebound state. When the top plate 113 is pulled and slid away from the bottom plate 111 until the top plate 113, connecting plate 112 and bottom plate 111 unfold and are stored in the embedding groove 101, the locking part 1135b engages with the locking part 1013 to lock the cup holder 11. At this time, the pressing part 1135a is in a compressed state.

[0049] According to one embodiment of this application, the mounting base 10 further includes a plug 102. The size of the plug 102 matches the size of the suspended portion 1131. When the bottom plate 111, the connecting plate 112, and the top plate 113 are rotated and folded to form a cup holder structure, the plug 102 is embedded in the suspended portion 1131 to block the suspended portion 1131.

[0050] In the embodiments of this application, reference is made to... Figure 1 and Figure 2 The mounting base 10 is provided with a cover 102 that matches the size of the bracket 1131. When the cup holder 11 is stored and hidden in the mounting base 10, the cover 102 can be fitted into the bracket 1131 of the top plate 113 to block the bracket 1131. This can prevent debris or garbage from entering the mounting groove 101 through the bracket 1131 and causing garbage accumulation, thereby keeping the mounting groove 101 clean. In addition, the cover 102 is used for the installation and positioning of the cup holder 11, which reduces the shaking of the cup holder 11 after it is locked to a certain extent.

[0051] It should be noted that the height of the cover 102 is slightly low, and there is a gap between the cover 102 and the top plate 113 in the height direction. When the top plate 113 slides in the sliding groove 1012, the cover 102 does not affect the unfolding or assembly of the cup holder 11. The design is ingenious and improves the user experience.

[0052] According to one embodiment of this application, referring to Figure 3 The bottom plate 111 is located at the bottom of the receiving cavity 114. The bottom plate 111 has a recess 1113 corresponding to the overhead part 1131. The recess 1113 is used to position the cup placed in the receiving cavity 114.

[0053] In this embodiment of the application, the bottom plate 111 has a recess 1113. When the cup holder 11 forms a cup support structure, the bottom plate 111 corresponds to the top plate 113, and the recess 1113 corresponds to the suspended part 1131. When the cup is inserted into the receiving cavity 114 through the suspended part 1131, the bottom end of the cup can abut against the recess 1113, thereby positioning the cup and making the cup more stable and improving the user experience.

[0054] The second technical solution provided in this application is: to provide a vehicle storage structure, including a mounting plate and the aforementioned folding cup holder 1, wherein the folding cup holder 1 is disposed on the mounting plate.

[0055] According to one embodiment of this application, the mounting plate includes a car door panel or a car seat back.

[0056] The vehicle storage structure of this application is installed in a car. The mounting plate includes a car door panel or a car seat back. The folding cup holder 1 is installed on the car door panel or a car seat back. The folding cup holder 1 can realize multiple combination functions according to user needs, which is convenient and quick, while meeting the customer's needs for maximizing space and diversifying interior functions.

[0057] In summary, the cup holder 11 is disposed in the mounting slot 101 of the mounting base 10. The cup holder 11 is formed by connecting the bottom plate 111, the connecting plate 112 and the top plate 113 in sequence. The connecting plate 112 is rotatably connected to the bottom plate 111 and the top plate 113 respectively. The bottom plate 111 is rotatably connected to the mounting base 10, and the top plate 113 is slidably connected to the mounting base 10. When the cup holder 11 is needed, the top plate 113 can slide towards the bottom plate 111 until the bottom plate 111, connecting plate 112, and top plate 113 rotate and fold to form a cup holder structure. The bottom plate 111, connecting plate 112, and top plate 113 form a support structure for the cup holder structure, forming a receiving cavity 114 for accommodating the cup. The cup or other objects that need to be placed can enter the receiving cavity 114 from the open portion 1131 on the top plate 113, so that the user can conveniently and quickly use the cup holder 11 to place the cup. In some embodiments, the bottom plate 111 is located at the bottom of the receiving cavity 114, and the bottom plate 111 has a recess 1113 corresponding to the open portion 1131. The recess 1113 is used to position the cup placed in the receiving cavity 114, so that the cup is placed more stably and the user experience is improved. When the cup holder 11 is not needed, the top plate 113 can slide away from the bottom plate 111 until the top plate 113, connecting plate 112, and bottom plate 111 unfold and are stored in the recessed groove 101. The cup holder 11 is then flattened and hidden in the mounting base 10, achieving a concealed state and not occupying space. The folding cup holder of this embodiment achieves multiple combination functions, which is convenient and quick, while meeting customers' needs for maximizing space and diverse combinations of interior functions.
