DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Reference below Figure 1-Figure 3 Describe the table board folding mechanism 100 according to the embodiment of the utility model. The side table board 1 is rotatably connected to the middle table board 2 and can be unfolded when in use to meet user needs, and can be folded up when not in use to save space. When the side table board 1 rotates relative to the middle table board 2, it is unlocked or locked by the locking component 5 of the locking structure 3. The locking component 5 cooperates with the support rod 4. The support rod 4 is used to support between the inner sides of the middle table board 2 and the side table board 1. After the locking structure 3 clamps the support rod 4, the support performance of the side table board 1 can be further enhanced by the support rod 4, thereby reducing the problem of the side table board 1 shaking easily when it is folded or unfolded to the extreme position through locking and support; in addition, the table board folding mechanism 100 of the embodiment of the utility model also has the functions of suppressing noise, lubrication and hovering, and can realize the transmission and support of the entire side table board 1 through the cooperation of the support rod 4, the locking structure 3 and the side table board 1.

[0031] Reference below Figure 1-Figure 3 The table top folding mechanism 100 according to an embodiment of the utility model is described, comprising: a middle table top 2, a side table top 1, a locking structure 3 and a support rod 4.

[0032] Among them, the side table panel 1 is rotatably connected to the middle table panel 2, and the locking structure 3 can be movably installed on the side table panel 1. The locking structure 3 has a locked state and an unlocked state, and the locking structure 3 is provided with at least two locking components 5. One end of the support rod 4 is rotatably connected to the middle table panel 2. When the locking structure 3 is in the locked state, one end of the support rod 4 is locked with one of the locking components 5 and the side table panel 1 and the middle table panel 2 are relatively fixed. When the locking structure 3 is in the unlocked state, the side table panel 1 can be rotated relative to the middle table panel 2 and the other end of the support rod 4 can be switched between at least two locking components 5.

[0033] In practice, the side table panel 1 and the middle table panel 2 are rotatably connected via the fourth rotating shaft 8. When the small table panel is not in use, the side table panel 1 and the middle table panel 2 can be folded together to save space. When the user is using the table, the side table panel 1 and the middle table panel 2 can be unfolded together for user use. The middle table panel 2 is fixed to the auxiliary instrument panel through the middle support 6 and the connecting piece, that is, located in front of the rear seats, to facilitate the rear users' entertainment or other work.

[0034] Specifically, the side table panel 1 is provided with a locking structure 3, and the locking structure 3 has two states, that is, the user can transform the locking structure 3 from an unlocked state and a locked state during operation, and the locking structure 3 is provided with at least two locking components 5. When there are two locking components 5, one of the locking components 5 is used to lock the support rod 4 when the side table panel 1 is folded to the maximum state, and the other locking component 5 can be used to lock the support rod 4 when the side table panel 1 is unfolded to a horizontal state. That is to say, the two locking components 5 are respectively suitable for the two common states of the small table panel.

[0035] Of course, there can be multiple locking components 5. Each time the locking components 5 are unlocked, one of the locking components 5 loosens the support rod 4 so that the support rod 4 can be moved to another locking component 5, thereby satisfying different states of the table top folding mechanism 100. The specific unlocking or locking of the locking structure 3 can be completed through manual operation.

[0036] Therefore, that is to say, when the side table panel 1 is in a folded state or an unfolded state, it is locked by the locking assembly 5. In addition, the locking assembly 5 cooperates with the support rod 4, and the support rod 4 is used to support between the inner sides of the center table panel 2 and the side table panel 1. After the support rod 4 is clamped in the locking structure 3, the support performance of the side table panel 1 can be further enhanced by the support rod 4, thereby reducing the problem of the side table panel 1 shaking easily when it is folded or unfolded to the extreme position through locking and support.

[0037] In addition, when the side table 1 is unfolded, it is locked by the locking structure 3 and supported by the support rod 4, so that the side table 1 can maintain its hovering function, and the entire side table 1 can be driven and supported by the cooperation of the locking structure 3 and the support rod 4 and under the premise of manual operation. For example, the distance between the end of the side table 1 away from the middle table 2 and the fourth rotation axis 8 is 151 mm, and the side table 1 with a length of 151 mm can be driven, locked and supported by the cooperation of the small locking structure 3 and the support rod 4. Moreover, the embodiment of the utility model only needs one middle support 6, and the support rod 4 is set at the connection between the middle table 2 and the side table 1 and is suspended in the air, that is, after the side table 1 is unfolded, there is not much support below the side table 1 of the vehicle, and the legs and feet of the people sitting on both sides of the middle support 6 can move more freely.

[0038] In some embodiments, the locking structure 3 includes an elastic member 7, a handle 32 and a movable plate 31. The handle 32 and the movable plate 31 are movably connected and are respectively movably installed on the side table panel 1. The handle 32 is suitable for driving the movable plate 31 to rotate relative to the side table panel 1 to switch to an unlocked state. The elastic member 7 is used to apply an elastic force to the handle 32 and the movable plate 31 to switch to a locked state. The handle 32 and the movable plate 31 are respectively provided with at least one locking component 5.

[0039] Specifically, the elastic member 7 can be connected between the buckle 32 and the side table board 1, or can be connected between the movable plate 31 and the side table board 1, and the buckle 32 and the movable plate 31 are movably connected to the side table board 1, such as the buckle 32 and the movable plate 31 are both rotatably connected to the side table board 1, when the elastic member 7 is arranged between the movable plate 31 and the side table board 1, the elastic member 7 is spaced apart from the rotatable connection between the movable plate 31 and the side table board 1, and when the elastic member 7 is arranged between the buckle 32 and the side table board 1, the elastic member 7 is spaced apart from the rotatable connection between the buckle 32 and the side table board 1; combined with Figure 2 and Figure 3 As shown, in the embodiment of the utility model, the elastic member 7 is connected to the movable plate 31, the other end of the elastic member 7 is connected to the side table board 1, and the buckle 32 and the movable plate 31 are movably connected, such as hinged.

[0040] When the center table panel 2 and the side table panel 1 of the table panel folding mechanism 100 are transformed from a folded state to an unfolded state, the user presses the handle 32 and rotates the side table panel 1 toward the unfolded state relative to the center table panel 2. The rotation of the handle 32 will drive the movable panel 31 to rotate, and the locking assembly 5 of the handle 32 and the movable panel 31 is separated from the side table panel 1 through the rotation of the handle 32 and the movable panel 31, that is, the locking assembly 5 is separated from the support rod 4, thereby changing the support rod 4 to an unlocked state. When the side table panel 1 is unfolded relative to the center table panel 2, the support rod 4 moves to another locking assembly 5, and the handle 32 is released. Then the elastic member 7 applies a force to the movable panel 31, so that the movable panel 31 and the handle 32 are moved to the initial state and fit with the side table panel 1, that is, the state in which the locking assembly 5 locks the support rod 4.

[0041] The embodiment of the utility model realizes locking and unlocking of the support rod 4 by setting the linkage mode of the elastic member 7, the buckle 32 and the movable plate 31. When resetting, the lock can be reset by the elastic member 7. The locking structure 3 is convenient for users to operate. The support rod 4 is locked or unlocked to allow the side table board 1 to rotate relative to the middle table board 2 and keep the side table board 1 in a certain state, which is convenient for users' entertainment and work.

[0042] In some embodiments, the handle 32 is rotatably connected to the side table panel 1 via a first rotating shaft 321, the movable plate 31 is connected to the side table panel 1 via a second rotating shaft 311, the handle 32 is also provided with a third rotating shaft 322, the movable plate 31 is provided with a movable groove 312, the third rotating shaft 322 is parallel to the first rotating shaft 321 and the second rotating shaft 311 and is rotated and slidably connected in the movable groove 312.

[0043] In practice, if Figure 2 As shown, the movable plate 31 and the handle 32 are distributed in sequence along the direction away from the center table board 2, that is, the handle 32 is located at the end away from the center table board 2, the movable plate 31 is movably connected with the handle 32, the locking assembly 5 is located on the side of the handle 32 and the movable plate 31 facing the side table board 1, and the handle 32 is provided with a pressing portion 323 at the end away from the center table board 2. In actual operation, the position of the hand 32 can be changed by pressing the pressing portion 323 of the hand 32, so that the hand 32 drives the movable plate 31 to move at the same time, and then the locking assembly 5 on the side of the hand 32 and the movable plate 31 close to the side table board 1 unlocks the support rod 4 to make the support rod 4 movable.

[0044] In addition, the first rotation axis 321 is parallel to the second rotation axis 311, that is, the rotation of the buckle 32 can synchronously drive the rotation of the movable plate 31, but due to the structural setting of the movable connection between the buckle 32 and the movable plate 31, for example Figure 2 When the handle 32 of the side table panel 1 on the middle right side is pressed to the limit position, the handle 32 rotates 14 degrees counterclockwise, and the movable plate 31 can rotate 16 degrees clockwise. When the pressing portion 323 of the handle 32 is pressed, the pressing portion 323 contacts the inner side of the side table panel 1, which can be the pressing limit angle of the handle 32. That is, at this time, the handle 32 cannot continue to press toward the side table panel 1, and the side table panel 1 has a certain limit on the handle 32. At this time, the movable plate 31 can rotate 16 degrees to make the locking assembly 5 release the support rod 4. Therefore, the first rotating shaft 321 of the handle 32 and the second rotating shaft 311 of the movable plate 31 are set in parallel, so that the range of rotation of the movable plate 31 driven by the rotation of the handle 32 can be more easily controlled.

[0045] The third rotation axis 322 of the buckle handle 32 is located between the first rotation axis 321 and the second rotation axis 311, and is parallel to the first rotation axis 321 and the second rotation axis 311, that is, when the buckle handle 32 rotates around the first rotation axis 321, the movable plate 31 rotates around the second rotation axis 311 at the same time, and the third rotation axis 322 is synchronized with the rotation of the buckle handle 32, and the third rotation axis 322 is located in the movable groove 312 of the movable plate 31 and is in sliding contact with the movable plate 31, and the rotation of the buckle handle 32 is limited by the contact between the pressing portion 323 of the buckle handle 32 and the side table panel 1, that is, when the pressing portion 323 of the buckle handle 32 rotates When the third rotating shaft 322 contacts the inner side of the side table panel 1, the third rotating shaft 322 is still located in the movable groove 312. Therefore, during the process of pressing or resetting the handle 32, the third rotating shaft 322 is always movable in the movable groove 312. The handle 32 and the movable plate 31 are movably connected through the third rotating shaft 322 and the movable groove 312, that is, the third rotating shaft 322 can rotate and slide in the movable groove 312, which can reduce the use of other connecting parts when the movable plate 31 and the handle 32 are connected. At the same time, the process of the handle 32 driving the movable plate 31 or the movable plate 31 driving the handle 32 to reset under the action of the elastic member 7 is smoother.

[0046] In some embodiments, when the movable plate 31 is in the initial state, the opening of the movable groove 312 faces the extension direction of the side table board 1 along the middle table board 2. That is to say, the opening of the movable groove 312 and one side of the buckle 32 are opposite, and when the buckle 32 rotates relative to the first rotation axis 321, the third rotation axis 322 of the buckle 32 can quickly move in the movable groove 312 and act on the movable plate 31. The opening of the movable groove 312 of the movable plate 31 faces the extension direction of the side table board 1 along the middle table board 2, that is, toward the buckle 32, so the buckle 32 slides more smoothly in the movable groove 312, and once the buckle 32 rotates, it can quickly cause the movable plate 31 to rotate, so that the buckle 32 and the movable plate 31 are more flexible when interacting with each other.

[0047] In some embodiments, the elastic member 7 is sleeved on the first rotating shaft 321 or the second rotating shaft 311 , and the elastic member 7 is connected to the side table board 1 .

[0048] When the lever 32 is pressed, the user can rotate the side table 1 while pressing the lever 32. When the lever 32 is pressed, the user can rotate the side table 1 while pressing the lever 32. When the lever 32 is pressed, the user can rotate the side table 1 while pressing the lever 32. When the lever 32 is pressed, the user can rotate the side table 1 while pressing the lever 32. When the lever 32 is pressed, the user can rotate the side table 1 while pressing the lever 32. When the lever 32 is pressed, the user can rotate the side table 1 while pressing the lever 32.

[0049] Specifically, the elastic member 7 is a spring, referring to Figure 3 As shown in the structure of the spring, the spring is at least mounted on both ends of the second rotating shaft 311, and the spring is led out from the middle of the second rotating shaft 311 and connected to the side table board 1. At this time, the spring is more evenly stressed when connected to the side table board 1, so that the spring can drive the movable plate 31 to return to its original position with better stability.

[0050] In some embodiments, each locking assembly 5 includes a clamping portion 51 and a limiting portion 52, and a limiting portion 52 is provided on the side of two adjacent clamping portions 51 close to each other; when the buckle 32 is pressed, the limiting portion 52 separates from the side table panel 1 to allow the support rod 4 to move from one of the clamping portions 51 to the other clamping portion 51, and when the buckle 32 is released, the clamping portion 51 and the limiting portion 52 at the position of the support rod 4 limit and lock the support rod 4.

[0051] In practice, the structure of the clamping portion 51 can be an L-shaped structure, such as the clamping portion 51 includes a supporting section 511 and a resisting section 512, wherein the support rod 4 is supported by the supporting section 511, and the two sides of the support rod 4 are respectively limited by the resisting section 512 and the limiting portion 52, so that the support rod 4 is locked in the space formed by the resisting section 512, the supporting section 511, the limiting portion 52 and the side table board 1, as shown in FIG. Figure 3 and Figure 5 The clamping portion 51 of the movable plate 31 shown in the figure is set to an L-shaped structure; of course, the structure of the clamping portion 51 can also be a semi-arc structure, such as Figure 5As shown in the figure, the clamping portion 51 of the buckle 32 is a semi-arc structure, which is used to support the support rod 4 and limit the support rod 4 on one side. The support rod 4 can be limited on one side by the structure of the semi-arc itself, or further limited by the first rotating shaft 321 provided on one side of the semi-arc structure. A limiting portion 52 is provided on the other side of the semi-arc structure. The locking performance of the support rod 4 is enhanced by the limiting portion 52. The space formed by the limiting portion 52, the semi-arc structure, the first rotating shaft 321 and the side table board 1 jointly limit and lock the support rod 4 that moves to the buckle 32.

[0052] In the embodiment of the utility model, two locking components 5 are provided, one is provided on the buckle 32 and the other is provided on the movable plate 31. Each locking component 5 includes a clamping portion 51 and a limiting portion 52. That is, when the buckle 32 drives the movable plate 31 to rotate relative to the side table plate 1, Figure 6 As shown in the figure, the shear head indicates the movement direction of each structure. The pressing portion 323 of the buckle 32 is pressed, and the buckle 32 rotates counterclockwise, driving the movable plate 31 to rotate clockwise. The support rod 4 located at the buckle 32 and locked by the clamping portion 51 and the limiting portion 52 of the buckle 32 is released. In the process of unfolding the side table board 1, the support rod 4 moves along Figure 6 When the support rod 4 moves upward, and when the support rod 4 moves to the clamping portion 51 in the movable plate 31, the buckle 32 is released, and the elastic member 7 applies a restoring force to the movable plate 31 so that the movable plate 31 and the buckle 32 can both return to their original states, that is, the locking state, locking the support rod 4 between the clamping portion 51 and the limiting portion 52.

[0053] In addition, the clamping portion 51 can be a bushing and directly connected to the movable plate 31 or the buckle 32, or the clamping portion 51 can be designed through the shape design of the movable plate 31 or the buckle 32 itself during manufacturing. Each moving mechanism, bushing, etc. are made of PA66, silicone and other materials to reduce noise.

[0054] The embodiment of the utility model locks or unlocks the support rod 4 by the cooperation of the clamping part 51 and the limiting part 52, and only needs to press or release the buckle 32, which is convenient and fast, and can lock the side table board 1 after the side table board 1 is fully unfolded. In addition, the inner wall of the clamping part 51 can be made of silicone material, which can reduce noise and buffer.

[0055] In some embodiments, the limiting portion 52 includes a roller 521 and a connecting shaft 522 . The connecting shaft 522 is disposed on at least one of the buckle 32 and the movable plate 31 . Each connecting shaft 522 is sleeved with a roller 521 .

[0056] That is to say, when the movable plate 31 has two locking components 5, the two limiting portions 52 and the two clamping portions 51 are all located at the movable plate 31, and when the buckle hand has two locking components 5, the two limiting portions 52 and the two clamping portions 51 are all located at the movable plate buckle hand 32. In the embodiment of the utility model, one locking component 5 is located at the movable plate 31 and the other locking component 5 is located at the buckle hand 32. A roller 521 is sleeved on the connecting shaft 522 located at the movable plate 31 to form a limiting portion 52 at the movable plate 31. The limiting portion 52 at the movable plate 31 cooperates with the clamping portion 51 of the movable plate 31 to form a locking component 5 of the movable plate 31. A roller 521 is sleeved on the connecting shaft 522 located at the buckle hand 32 to form a limiting portion 52 at the buckle hand 32. The limiting portion 52 of the buckle hand 32 cooperates with the clamping portion 51 of the buckle hand 32 to form a locking component 5.

[0057] Reference Figure 3 As shown, when the side table panel 1 is adjusted from the folded state to the unfolded state, that is, the support rod 4 moves from the locking assembly 5 at the buckle 32 to the locking assembly 5 at the movable plate 31, when the support rod 4 passes through the limiting portion 52 at the buckle 32, the limiting portion 52 is a roller 521 structure, which can reduce the friction resistance between the support rod 4 and the buckle 32 and reduce noise, and the rotation of the roller 521 relative to the connecting shaft 522 can promote the movement of the support rod 4. In addition, the contact positions of the buckle 32 and the movable plate 31 with the support rod 4 are all set to a smooth arc structure, which facilitates the support rod 4 to move from one locking assembly 5 to another locking assembly 5.

[0058] In addition, guide structures 9 are provided on both sides of the buckle 32 and the movable plate 31. Figure 4 As shown, each guide structure 9 is connected to the end of the first rotating shaft 321 of the buckle 32 and to the end of the second rotating shaft 311 of the movable plate 31. The surface of the guide structure 9 is set to be smooth, and the two ends of the guide structure 9 are the connection points of the first rotating shaft 321 and the second rotating shaft 311. The two ends of the guide structure 9 are higher than the middle section of the guide structure 9 and can be used as a limit. That is to say, the movable range of the support rod 4 is along the guide structure 9, so that the movement of the support rod 4 between the buckle 32 and the locking assembly 5 of the movable plate 31 has a better limiting and guiding effect.

[0059] In some embodiments, the support rod 4 includes a first connection portion 43, a support portion 41 and a movable clamping portion 42. The first connection portion 43 and the movable clamping portion 42 are respectively bent and connected to the two ends of the support portion 41. The first connection portion 43 is rotatably connected to the center table board 2. The movable clamping portion 42 is unlocked or locked to the side table board 1 and the locking structure 3. The support portion 41 is used to support the inner side of the center table board 2 and the side table board 1.

[0060] In practice, the support rod 4 is rotatably connected to the center table board 2 via the first connecting portion 43, and the movable clamping portion 42 of the support rod 4 moves between the locking components 5 of the buckle 32 and the movable plate 31. By setting the first connecting portion 43 and the movable clamping portion 42 of the support rod 4 as a structure bent with the support portion 41, the support rod 4 can be conveniently connected to the center table board 2 and the side table board 1 in different directions and supported between the center table board 2 and the side table board 1.

[0061] For example, the movable clamping portion 42 and the first connecting portion 43 of the support rod 4 can be arranged parallel to each other, and the movable clamping portion 42 and the first connecting portion 43 are both parallel to the fourth rotating axis 8 rotatably connected between the center table board 2 and the side table board 1. Then, in the process of pressing the buckle 32 and rotating the side table board 1 relative to the center table board 2, the movable clamping portion 42 is more likely to move in the direction close to or away from the fourth rotating axis 8, thereby reducing the position deviation of the support rod 4 when moving, and the movable position of the support rod 4 is easy to control.

[0062] In some embodiments, there are two side table panels 1, which are rotatably connected to the two sides of the center table panel 2. In actual application, the center table panel 2 can be connected to one side table panel 1, or one side table panel 1 can be connected to each side of the center table panel 2, which can be determined according to the actual area of ​​the center table panel 2 and the side table panel 1 after unfolding and the needs of users; when there are two side table panels 1, which are respectively connected to the two sides of the center table panel 2, the locking structures 3 inside the two side table panels 1 are the same, and the structures of the buckles 32 and the movable panels 31 in the two side table panels 1 are the same, that is, the user can choose to fold or unfold one side table panel 1 or fold or unfold two side table panels 1 at the same time according to actual needs, which can meet the needs of different users and has higher flexibility.

[0063] The embodiment of the utility model further discloses a vehicle, including the above-mentioned table board folding mechanism 100. The middle table board 2 and the side table board 1 of the embodiment of the utility model are rotatably connected and can be unfolded when in use to meet the needs of users, and can be folded up when not in use to save space. When the side table board 1 rotates relative to the middle table board 2, it can be unlocked or locked by the locking assembly 5 of the locking structure 3. The locking assembly 5 cooperates with the support rod 4, and the support rod 4 is used to support between the inner sides of the middle table board 2 and the side table board 1. After the support rod 4 is clamped on the locking structure 3, the support performance of the side table board 1 can be further enhanced by the support rod 4, thereby reducing the problem that the small table board is easy to shake when it is folded or unfolded to the extreme position, and enhancing the comfort of users.
