[0041] As shown in Figures 1 to 10 a shieldable linkage automobile table board, comprising:

[0042] a base 1 for being mounted on a predetermined vertical surface (for example, an inclined backrest of a car seat or other position);

[0043] a table board 2, an upper wall of the table board 2 being provided with a driving slot 20;

[0044] a linkage assembly, the linkage assembly comprising a first curved link 31, a second curved link 32, a first swing link 41 and a second swing link 42,

[0045] a first end of the first curved link 31 being pivotally mounted at a lower position of the base 1, and a second end being pivotally mounted at a rear position of the driving slot 20;

[0046] a first end of the second curved link 32 being pivotally mounted at an upper position of the base 1, and a second end being pivotally mounted at a front position of the driving slot 20;

[0047] the second end of the second curved link 32 extending a raised portion 324, the raised portion 324 being pivotally connected with a first end of the first swing link 41,

[0048] a second end of the first swing link 41 being slidingly mounted at a first end of the second swing link 42, and a second end of the second swing link 42 being pivotally connected with the rear position of the driving slot 20;

[0049] when the table board 2 and the base 1 are folded, the second end of the first curved link 31 and a middle portion of the second curved link 32 are away from each other, one side of the first swing link 41 is close to the second curved link 32, and the first end of the second swing link 42 slides to a middle position of the first swing link 41;

[0050] when the table board 2 and the base 1 are unfolded, the second end of the first curved link 31 swings to the middle portion of the second curved link 32, an upper wall of the second curved link 32 and an upper wall of the first swing link 41 are at the same horizontal position, and the first end of the second swing link 42 slides to a second end position of the first swing link 41.

[0051] The positional relationship is that the position close to the base is rear, and the position close to the front end of the table board is front.

[0052] when the table board 2 and the base 1 are folded, the base 1 is generally located in the slot of the backrest, thereby realizing the storage of the table board 2;

[0053] when it is needed to be unlocked, the table board 2 is pulled, thereby driving the first curved link 31 and the second curved link 32 to swing towards the middle portion until the second end of the first curved link 31 swings to the middle portion of the second curved link 32 to realize the limiting,

[0054] The first swing rod 41 slides along the rear part of the second swing rod 42 while swinging until the first end of the second swing rod 42 slides to the rear end position of the first swing rod 41, thereby achieving clamping and limiting, and thereby achieving horizontal placement and positioning of the table board 2.

[0055] The design point lies in the design of the raised part 324 and the relative sliding of the first swing rod 41 and the second swing rod 42, thereby achieving linkage.

[0056] Specifically, the second curved rod 32 comprises a first branch arm 321, a second branch arm 322 curvedly extended from the first branch arm 321, and a curved arm 323 extended from the second branch arm 322, and the raised part 324 is arranged at the end of the curved arm 323 and has a predetermined shape, which can achieve both avoidance and linkage and folding.

[0057] In the embodiment of the utility model, when in the unfolded state, the upper wall of the second branch arm 322 is flush with the upper wall of the first swing rod 41, and the upper wall of the second end of the first curved rod 31 is attached to the lower wall of the second branch arm 322.

[0058] Thereby, the predetermined positioning effect is achieved, and the first curved rod 31 and the second curved rod 32 form a stable triangle, thereby ensuring the relative stability of the table board 2 and the base frame 1.

[0059] Specifically, an avoidance interval 51 is arranged between the upper wall of the curved arm 323 and the upper wall of the second branch arm 322, and when the first swing rod 41 is attached to the end of the curved arm 323, the avoidance interval 51 is adapted to the Z-axis height of the first swing rod 41, thereby achieving linkage and mutual positioning, and further, a recessed position is arranged on the lower wall of the first swing rod 41, thereby achieving clamping and avoidance.

[0060] In the embodiment of the utility model, the recessed position of the curved arm 323 forms an accommodating interval 52, and in the folded state, part of the first swing rod 41 and the second swing rod 42 extends into the accommodating interval 52, thereby making the linkage assembly occupy a smaller size in the height direction in the folded state.

[0061] Specifically, the first swing rod 41 is provided with a guide groove 61, the first end of the second swing rod 42 is provided with a guide sliding block 62 matched with the guide groove 61, and the guide sliding block 62 can slide along the length direction of the guide groove 61, thereby achieving relative cooperation of the first swing rod 41 and the second swing rod 42 through the guide groove 61 and the guide sliding block 62 when the raised part 324 drives the first swing rod 41 to move.

[0062] The guide groove 61 is provided with a locking groove 63 near the second end of the first swing rod, so that when the table board is turned outward, the first torsional spring 71 drives the guide sliding block 62 to slide toward the position of the locking groove 63, thereby achieving opening and locking.

[0063] When it is necessary to unlock, the table board is pressed downward, thereby overcoming the elastic force of the first torsional spring 71, and the guide sliding block 62 is moved toward the position close to the first end of the first swing lever, thereby realizing linkage;

[0064] The locking groove 63 can be non-coplanar, such as the curvedly extending locking groove 63 shown in the figure.

[0065] In the embodiment of the utility model, the second end of the first swing lever 41 is provided with a first torsional spring 71, the first torsional spring 71 is used for driving the first end of the first swing lever 41 to slide toward the position close to the second end of the first swing lever 41 of the guide groove 61, thereby realizing the relative locking of the first swing lever 41 and the second swing lever 42, when it is necessary to unlock, the downward pressure is applied to the second end of the first swing lever 41, thereby making the first end of the second swing lever 42 away from the rear end of the guide groove 61, thereby realizing the unlocking of the table board 2.

[0066] Specifically, the first end of the second curved lever 32 is provided with a second torsional spring 72, the second torsional spring 72 is used for applying the elastic force of the second end of the second curved lever 32 to the base frame 1, thereby realizing the automatic folding of the table board 2, that is, the first curved lever 31 and the second curved lever 32 are close to each other.

[0067] In the embodiment of the utility model, the first curved lever 31, the second curved lever 32, the first swing lever 41 and the second swing lever 42 are in the same axial position, and the non-misaligned structure is adopted, thereby realizing the linkage and cooperation of the folding and unfolding of the linkage assembly, and making the volume smaller and more stable.

[0068] Specifically, the side close to the base frame 1 of the driving groove 20 is provided with an opening 81, and the side away from the opening 81 of the driving groove 20 is provided with a positioning hole 82,

[0069] When being in the folded state, the second end of the first swing lever 41 and the first end of the second swing lever 42 extend out of the positioning hole 82;

[0070] When being in the unfolded state, the first swing lever 41 and the second swing lever 42 extend into the driving groove 20, thereby realizing the hiding of the linkage assembly in the table board 2, and avoiding the exposure of the linkage assembly.

[0071] In actual design, two groups of linkage assemblies are arranged at intervals, and a connecting rod is arranged or not arranged between the two groups of linkage assemblies, thereby realizing the predetermined synchronization and linkage.

[0072] The above merely describes preferred embodiments of the present application, and is not intended to limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the inventive concept of the present application, as described in the present application specification and drawings, is included in the patent protection scope of the present application.
