[0093] Specifically, pressing the second lock button 330 (ie, along the Figure 7 The third projection 332 of the second locking button 330 is pressed into the fifth sliding groove 321 of the fourth connecting rod 320 (see Fig. 10B ), the teeth of the third boss 332 mesh with the teeth of the fifth sliding groove 321, so that the second locking button 330 and the fourth connecting rod 320 cannot rotate or slide relative to each other, thereby locking the fourth connecting rod 320. In addition, since the diameter of the second button body 331 of the second locking button 330 is equal to the width of the fourth sliding groove 311, the second locking button 330 can still slide along the fourth sliding groove 311, so that the third connecting rod 310 cannot be locked. During the locking process, the second locking button 330 moves from Fig. 10A The status moves to Fig. 10B status.

[0094] After locking the fourth connecting rod 320, the total length L300 and the angle of the connecting rod assembly 300 can change, but the maximum value of the total length L300 of the connecting rod assembly 300 is locked, and the limit value of the angle that the connecting rod assembly 300 can reach is also locked. Among them, the total length L300 of the connecting rod assembly 300 refers to the distance from the first end 312 of the third connecting rod 310 to the first end 323 of the fourth connecting rod 320, and the angle of the connecting rod assembly 300 refers to the angle between the third connecting rod 310 and the fourth connecting rod 320. Specifically, when the second locking button 330 is inserted into the second end of the fourth sliding groove 311 of the third connecting rod 310 (the position close to the second end 313 of the third connecting rod 310), the total length L300 of the connecting rod assembly 300 reaches the maximum value that can be reached in the state where the fourth connecting rod 320 is locked this time. That is, each time the fourth connecting rod 320 is locked, the maximum value that the total length L300 of the connecting rod assembly 300 can reach no longer changes.

[0095] By pressing the second fixing cover 340 , the second locking button 330 can no longer lock the fourth link 320 , that is, the fourth link 320 can be unlocked.

[0096] Specifically, press the second fixing cover 340 (ie, along Figure 7The second fixing cover 340 pushes the second locking button 330 to move, so that the third boss 332 of the second locking button 330 is disengaged from the fifth sliding groove 321 of the fourth connecting rod 320 (see Fig. 10A ) to unlock the fourth link 320. During the unlocking process, the second locking button 330 is moved from Fig. 10B The status moves to Fig. 10A status.

[0097] If the fourth link 320 is locked and kept locked (i.e., the maximum value of the total length L300 of the link assembly 300 does not change), and the angle of the seat back back plate 900 is not adjusted, then the next time the table board assembly 100 is used, when the table board assembly 100 is rotated to a horizontal state, the total length L300 of the link assembly 300 just reaches the maximum value that it can reach. At this time, since the total length change and angle change of the link assembly 300 and the link assembly 200 are synchronized, the first button body 231 of the first locking button 230 is just inserted into the locking hole 211 and the connecting hole 213 of the first link 210. At this time, the table board assembly 100 can be kept in a horizontal state by only pressing the first locking button 230 again. That is, by locking the fourth link 320, the maximum value of the total length of the link assemblies 200 and 300 corresponding to the table board assembly 100 being kept in a horizontal state can be recorded, so that the table board assembly 100 can be directly rotated to a horizontal state next time.

[0098] In an exemplary embodiment, Fig.12 As shown, the left edge and / or the right edge of the first surface 101 of the table top assembly 100 has a receiving groove 102, such as Fig.13 As shown, the front side wall and the rear side wall of the receiving groove 102 have mounting holes 103 .

[0099] like Fig.12 As shown, the seat back table further includes: a hook 400, the first end of the hook 400 has a hook portion 402 (see Fig.14 ).

[0100] Among them, Fig.14 As shown, the second end of the hook 400 has an axis 401 corresponding to the mounting hole 103, and the axis 401 is inserted into the mounting hole 103 so that the hook 400 can be rotatably mounted in the receiving groove 102. The hook 400 can rotate around the axis 401 to be accommodated in the receiving groove 102 (see Fig.12 ), or is opened (see Fig.15 When the hook 400 is opened, the hook portion 402 can hang items (see Fig.16 ).

[0101] In other embodiments, the positions of the shaft 401 and the mounting hole 103 can be interchanged, that is, the mounting hole 103 is set at the second end of the hook 400, and the shaft 401 is set at the front side wall and the rear side wall of the accommodating groove 102 (this situation is not shown in the figure).

The cup holder 111 can be slidably installed in the cup holder compartment. The cup holder 111 has a cup holder body 112 and a flippable bracket 113. The bracket 113 can be rotated to the bottom of the cup holder body 112. The cup holder body 112 has a through opening 114 for the cup to pass through.

[0108] If the diameter of the cup is larger than the diameter of the through opening 114, the cup can be directly placed on the through opening 114 of the cup holder body 112 (see Fig. 20 If the diameter of the cup is smaller than the diameter of the through hole 114, we can rotate the bracket 113 to the bottom of the cup holder body 112 (see Fig.21 ), and then place the cup on the cup holder body 112 and the bracket 113, so that the bracket 113 holds the cup (see Fig. 22 ).

[0109] In an exemplary embodiment, Figure 1A As shown, the rear side of the seat back back plate 900 has a storage compartment 901 , and the table board assembly 100 can be stored in the storage compartment 901 .

[0110] In an exemplary embodiment, Figure 1A As shown, the side wall of the storage compartment 901 has a charging device 902.

[0111] In an exemplary embodiment, Figure 1B and Fig.23 As shown, the seat back back plate 900 has a locking groove 903, in which a locking member 904 capable of moving along the locking groove 903 is installed, and the table board assembly 100 has a slot 115 corresponding to the locking member 904 (see Figure 1A and Fig.24 ), a portion of the locking member 904 can be inserted into the slot 115 to lock the table top assembly 100 in the receiving compartment 901.

[0112] In an exemplary embodiment, Figure 1A and Fig.24 As shown, the seat back table further includes: a makeup mirror 905.

[0113] The side wall of the storage compartment 901 has a makeup mirror installation groove 906, and the left and right walls of the makeup mirror installation groove 906 have installation holes. The makeup mirror 905 is installed in the installation hole of the makeup mirror installation groove 906 through an axis, so that the makeup mirror 905 can rotate around the axis, so that the makeup mirror 905 can be rotatably installed in the makeup mirror installation groove 906. The user can adjust the angle of the makeup mirror 905 according to actual needs (see Fig.24 and Fig.25 ).

[0114] like Figure 1A As shown, the makeup mirror installation groove 906 has a makeup mirror cover plate 907 that can be pushed, and the makeup mirror cover plate 907 can cover the makeup mirror 905.

[0115] The embodiment of the utility model further provides a vehicle equipped with the seat back table board. Other components and functions of the vehicle of the embodiment of the utility model are known to those skilled in the art, and will not be described in detail to reduce redundancy.

[0116] The operation of the seat back table board of the implementation scheme of the utility model will be described below with reference to the accompanying drawings.

[0117] In the initial state, the table board assembly 100 is locked in the receiving compartment 901. At this time, a portion of the locking member 904 is inserted into the slot 115 of the table board assembly 100. The seat backrest 900 is in a vertical state (see Figure 1B and Fig.11A ).

[0118] In addition, if Fig.26 As shown, the first button body 231 of the first locking button 230 is inserted into the first sliding groove 212 of the first connecting rod 210, close to the first end 214, and inserted into the second sliding groove 221 and the second end of the third sliding groove 222 of the second connecting rod 220 (close to the second end 224 of the second connecting rod 220). The second connecting rod 220 and the first connecting rod 210 are not locked by the first locking button 230, so that the first button body 231 of the first locking button 230 can slide along the second sliding groove 221 and the third sliding groove 222 of the second connecting rod 220, and can slide along the first sliding groove 212 of the first connecting rod 210.

[0119] When the table top assembly 100 is in use, the locking member 904 is pushed upwards and disengaged from the slot 115 so as to no longer lock the table top assembly 100 .

[0120] The table top assembly 100 is pressed downward, the table top assembly 100 rotates downward and backward, and the first connecting rod 210 rotates along the first end 214 of the first connecting rod 210. Fig.26The second connecting rod 220 rotates in the direction of the arrow W1, and the second connecting rod 220 rotates along the first end 223 of the second connecting rod 220. Fig.26 The first locking button 230 is rotated in the direction of the arrow P1, so that the first button body 231 of the first locking button 230 slides in the second sliding groove 221 and the third sliding groove 222 of the second connecting rod 220, and can slide in the first sliding groove 212 of the first connecting rod 210 toward the second end 215 of the first connecting rod 210 (i.e., along the Fig.26 moves in the direction of arrow Q1).

[0121] When the table top assembly 100 is rotated to a horizontal state (see Fig. 27 ), the first button body 231 of the first locking button 230 is inserted into the locking hole 211 and the connecting hole 213 of the first connecting rod 210 (see Fig. 6A ), and the first button body 231 of the first locking button 230 is inserted into the second sliding groove 221 of the second link 220 and the second end of the third sliding groove 222 (the position close to the second end 224 of the second link 220), at this time, the first link 210 and the second link 220 are on the same straight line, and the total length L200 of the link assembly 200 reaches the maximum value it can reach. And the specific value of the maximum value reaches the first maximum value.

[0122] Press the first lock button 230 (ie, Figure 3 The first link 210 and the second link 220 are locked by moving the first link 210 in the direction of the arrow A in the middle (moving in the direction of the arrow A in the middle) and at this time, the total length of the link assembly 200 remains unchanged (i.e., maintains the maximum length) so that the table top assembly 100 remains in a horizontal state. The total length L300 of the link assembly 300 also reaches a maximum value (equal to the maximum value that the total length of the link assembly 200 can reach), and the third link 310 and the fourth link 320 are also in the same straight line. That is, when the table top assembly 100 is in a horizontal state, the total length L300 of the link assembly 300 is at a maximum value (equal to the maximum value that the total length of the link assembly 200 can reach).

[0123] Press the second lock button 330 (ie, Figure 7 Move in the direction of arrow C in the figure to lock the fourth connecting rod 320.

[0124] When the table top assembly 100 is not needed, the first fixing cover 240 is pressed to unlock the first link 210 and the second link 220, and the table top assembly 100 is retracted into the storage compartment 901. At this time, the first link 210 and the second link 220 of the link assembly 200 are not locked, the third link 310 of the link assembly 300 is not locked, and the fourth link 320 of the link assembly 300 is locked.

[0125] In the process of retracting the table top assembly 100 into the storage compartment 901, the table top assembly 100 rotates upward and forward, and the first connecting rod 210 rotates along the first end 214 of the first connecting rod 210. Fig. 27 The second connecting rod 220 rotates in the direction of the arrow W2, and the second connecting rod 220 rotates along the first end 223 of the second connecting rod 220. Fig.26 The first locking button 230 is rotated in the direction of the arrow P2 in FIG. 1 , so that the first button body 231 of the first locking button 230 slides in the second sliding groove 221 and the third sliding groove 222 of the second connecting rod 220, and can slide in the first sliding groove 212 of the first connecting rod 210 toward the first end 214 of the first connecting rod 210 (i.e., along the Fig. 27 moves in the direction of arrow Q2).

[0126] When the table top assembly 100 needs to be used again, there are two situations. The first situation is that the angle of the seat back panel 900 has not been adjusted, and the second situation is that the angle of the seat back panel 900 has been adjusted.

[0127] If the angle of the seat backrest 900 is not adjusted, push the locking member 904 upward to unlock the table board assembly 100 again. When the table board assembly 100 is pressed downward, the total length L300 of the connecting rod assembly 300 reaches its maximum value (equal to the first maximum value), the table board assembly 100 just rotates to a horizontal state, and the total length L200 of the connecting rod assembly 200 reaches its maximum value (equal to the first maximum value). At this time, it is only necessary to press the first locking button 230 again to lock the total length L200 of the connecting rod assembly 200 at the maximum value (equal to the first maximum value) this time, so that the table board assembly 100 remains in a horizontal state.

[0128] When the seat back plate 900 is adjusted to an angle α with the vertical plane, the operation steps are as follows:

[0129] The locking member 904 is pushed upward to unlock the table top assembly 100 again. When the table top assembly 100 is lowered to the maximum position again, the table top assembly 100 is not in a horizontal state (there is an angle with the horizontal plane).

[0130] The second fixing cover 340 is pressed to unlock the fourth link 320, and the table top assembly 100 is rotated upward to a horizontal state, at which time, the angle between the table top assembly 100 and the seat back 900 changes. In the process of rotating the table top assembly 100 to a horizontal state, the first locking button 230 slides along the second sliding groove 221 and the third sliding groove 222 of the second link 220 toward the first end 223 of the second link 220, and changes the angle between the first link 210 and the second link 220, and the second locking button 330 slides along the fifth sliding groove 321 and the sixth sliding groove 322 of the fourth link 320 toward the first end 323 of the fourth link 320, and changes the angle between the third link 310 and the fourth link 320.

[0131] Press the first locking button 230 to lock the first link 210 and the second link 220, and press the second locking button 330 to lock the fourth link 320 to lock the total length L300 of the link assembly 300 again to the maximum value that can be reached, which is the second maximum value (the second maximum value is less than the first maximum value).

[0132] When the table top assembly 100 is not needed, the first fixing cover 240 is pressed to unlock the first connecting rod 210 and the second connecting rod 220 , and the table top assembly 100 is retracted into the storage compartment 901 .

[0133] Based on the previous angle α between the seat back plate 900 and the vertical plane, when the table board assembly 100 needs to be used again, there are three situations. The first situation is that the angle of the seat back plate 900 has not been adjusted (for example, Fig. 11B ), the second is that the seat backrest 900 is adjusted to an angle greater than α with the vertical plane (e.g. Fig. 11C ), the third is that the seat back plate 900 is adjusted to an angle less than α with the vertical plane (e.g. Fig.11A ).

[0134] When the angle of the seat back panel 900 is not adjusted, the operation steps are the same as before and will not be repeated.

[0135] When the included angle between the seat back plate 900 and the vertical plane is greater than α, for example, Fig. 11C β in (β is greater than α), the operation steps and FIG. 11A to FIG. 11B The operation steps are the same and will not be repeated here.

[0136] When the angle between the seat back plate 900 and the vertical plane is less than α, for example, the angle is zero, that is, the seat back plate 900 is in a vertical state, if the fourth connecting rod 320 is not unlocked, even if the total length L300 of the connecting rod assembly 300 can reach the maximum value (the maximum value at this time is equal to the second maximum value, and the second maximum value is less than the first maximum value), the table board assembly 100 still cannot be rotated to a horizontal state, but is in a state of tilting upward and backward. At this time, it is necessary to first unlock the fourth connecting rod 320, then rotate the table board assembly 100 to a horizontal state, and then lock the first connecting rod 210, the second connecting rod 220 and the fourth connecting rod 320.

[0137] If you need to hang an item (such as a bag), open the hook 400 and hang the item on the hook 400 (see Fig.16 ).

[0138] If it is necessary to clamp an electronic product such as a mobile phone 500, at least one of the two clamping devices 105 is first moved to leave a sufficient distance between the two clamping devices 105, and then the mobile phone 500 is inserted into the placement slot 104, and finally the clamping device is moved so that the two clamping devices 105 clamp the mobile phone 500 (see Fig.28 ).

[0139] When the mobile phone 500 needs to be charged, the mobile phone 500 or other electronic products are first placed horizontally on the first surface 101 of the table board assembly 100, and the two clamping devices 105 clamp the mobile phone 500, and then the charging cable is plugged into the charging device 902 (see Fig.29 ).

[0140] The cover 110 can be opened to take out cosmetics, medicines, etc. from the storage compartment 109.

[0141] When a cup needs to be placed, pull the cup holder 111 so that the cup holder 111 slides out of the cup holder compartment (see Fig.18 If the diameter of the cup is larger than the diameter of the through hole 114, the cup can be directly placed on the through hole 114 of the cup holder body 112 (see Fig. 20 ), if the diameter of the cup is smaller than the diameter of the through hole 114, we can rotate the bracket 113 to the bottom of the cup holder body 112 (see Fig.21 ), and then place the cup on the cup holder body 112 and the bracket 113, so that the bracket 113 holds the cup (see Fig. 22 ).

[0142] When it is necessary to fix the makeup, open the makeup mirror cover 907 and adjust the makeup mirror 905 to a suitable angle to fix the makeup.
