[0041] In this embodiment, a limiting groove 411 is provided in the fitting collar 41. The end of the forearm adjusting motor 5 protrudes a first connecting ear 51, and the first connecting ear 51 is fastened in the limiting groove 411, so that the forearm adjusting motor 5 is fastened to the adjusting forearm 4. During implementation, the end of the forearm adjusting motor 5 is fixed in the fitting collar 41 through the assembly of screws, and the first connecting ear 51 is clamped and fixed in the limiting groove 411.

[0042] The forearm adjusting motor 5 has a third D-shaped drive shaft 59. During implementation, the third D-shaped bushing 32 of the adjusting boom 3 is fastened to the third D-shaped drive shaft 59 of the forearm adjusting motor 5, so as to realize the synchronous drive of the adjusting boom 3 on the forearm adjusting motor 5.

[0043] Preferably, the central axis direction F1 of the fitting collar 41 is perpendicular to the central axis direction F2 of the first D-shaped bushing 42, and the central axis directions of the second D-shaped bushing 31 and the third D-shaped bushing 32 are parallel.

[0044] The function of such a setting is: through the linkage of the adjusting boom 3 and the adjusting forearm 4, degrees of freedom are formed in three mutually perpendicular directions of the tabletop body 6, so as to actively adjust the tabletop body 6.

[0045] Further, the tabletop body 6 is flat. In this embodiment, a first connecting seat 61 is provided at the bottom of the tabletop body 6. The first connecting seat 61 is a fitting structure with a limiting structure, and its structure is the same as that of the second connecting seat 11. Its function is to connect the end adjusting motor 7. The end adjusting motor 7 in this embodiment uses the same motor structure as the forearm adjusting motor 5 and the boom adjusting motor 2.

[0047] Preferably, a retaining ring is installed on the first D-shaped drive shaft 79 to keep the first D-shaped shaft sleeve 42 relatively fastened.

[0048] The function of the retaining ring is to fix the shaft end. In this embodiment, retaining rings with the same function are also respectively arranged on the second D-shaped drive shaft 29 and the third D-shaped drive shaft 59.

[0049] In the specific implementation of the in-vehicle table structure in this embodiment, by providing the table board body 6 with adjustment joints with multiple degrees of freedom, for example: the corresponding positions of the big arm adjustment motor 2, the small arm adjustment motor 5 and the end adjustment motor 7, the table board body 6 has the ability to actively adjust in the opposite direction following the vehicle attitude under different working conditions and always remains horizontal in the working state, for example: by adjusting the table board body 6 in the horizontal, vertical and vertical directions relative to itself.

[0050] It can be understood that the operator can issue a control through voice or the central control virtual button or the physical button. For example: in this embodiment, the in-vehicle table structure further includes: a sensor connected to the table board body 6 and a controller for respectively adjusting and controlling the big arm adjustment motor 2, the small arm adjustment motor 5 and the end adjustment motor 7 according to the pitch angle, yaw angle, roll angle of the table board body and / or the three-axis acceleration data information of the table board body obtained by the sensor.

[0051] Through the coordinated control of the controller and the sensor on the big arm adjustment motor 2, the small arm adjustment motor 5 and the end adjustment motor 7, the table board body 6 is always in a horizontal working state, improving the user experience.

[0052] At the same time, the operator can set the working angle of the table board body 6, which is implemented by respectively setting the absolute working positions of the big arm adjustment motor 2, the small arm adjustment motor 5 and the end adjustment motor 7, such as Figure 13 The schematic diagram of adjusting the state of the backrest 1 relative to the seat cushion 81 through the first motor 82 and the second motor 83 and then adjusting the state of the table board body 6 with multiple degrees of freedom. The operator can conveniently adjust the position and angle of the table board body 6 through the user control interface to meet different usage requirements.

[0053] Specifically: the adjustment situations of the position and angle of the table board body 6 realized through the coordinated control of the controller and the sensor on the big arm adjustment motor 2, the small arm adjustment motor 5 and the end adjustment motor 7 include:

[0054] (1) The table board body 6 is in a retracted state and not unfolded, as Figure 10 shown. During implementation, the big arm adjustment motor 2, the small arm adjustment motor 5 and the end adjustment motor 7 are in the zero position. When the user issues an unfolding command through voice or the central control virtual button or the physical button, the three adjustment motors of the table board start to move to the working angle.

[0055] Among them: The user can set the absolute working angle of the table board body 6, that is, the absolute working positions of the large arm adjustment motor 2, the small arm adjustment motor 5, and the end adjustment motor 7, and then enter the working state based on the adjustment of the backrest 1 by the user. In other embodiments, the user can set the absolute working angle of the small table board by himself.

[0056] (2) When the table board body 6 is traveling at a constant speed on a horizontal road, the position and angle of the table board body 6 are as Figure 1 shown. During implementation, the active small table board controller AB_MCU reads the small table board pitch angle Board_Pitch, the small table board yaw angle Board_Yaw, the small table board roll angle Board_Roll, the X-axis acceleration X_Acc, the Y-axis acceleration Y_Acc, and the Z-axis acceleration Z_Acc through the small table board gyroscope Board_Gyro. When Board_Pitch is 0, the large arm adjustment motor 2, the small arm adjustment motor 5, and the end adjustment motor 7 do not make any adjustments.

[0057] (3) When the vehicle enters an uphill or downhill road, keep the table board body 6 always horizontal in the pitch direction, as Figure 11 shown. During implementation, Board_Pitch will quickly read the current slope value, and the small arm adjustment motor 5 will make an angle adjustment to quickly adjust Board_Pitch to 0 to keep the small table board always horizontal in the pitch direction.

[0058] (4) When the vehicle is traveling on a road with a lateral tilt angle, keep the table board body 6 always horizontal in the pitch direction, as Figure 12 shown. During implementation, the small table board gyroscope roll angle Board_Roll will read the current lateral slope value of the vehicle, and the end adjustment motor 7 will quickly adjust according to Board_Roll to adjust Board_Roll to 0 to keep the small table board always horizontal in the transverse direction.

[0059] (5) In the case where the table board body 6 needs to be adjusted transversely-longitudinally-compoundly. During implementation, when both Board_Pitch and Board_Roll are not zero, the longitudinal adjustment and the transverse adjustment will be carried out simultaneously.

[0060] The longitudinal acceleration and deceleration adjustment are carried out through the small arm adjustment motor 5. When the vehicle accelerates during driving, the X-axis acceleration X_Acc will read a non-zero value, and the angle adjustment of the small arm adjustment motor 5 is used to compensate for the overturning force generated by the heavy object on the table board body 6 during acceleration and deceleration. The calculation method is: arctan[(m·X_ACC - μ·mg) / (μ·m·X_ACC)].

[0061] Lateral acceleration and deceleration adjustment is performed by the end adjustment motor 7. When the vehicle accelerates during driving, the Y-axis acceleration Y_Acc will read a non-zero value, and adjustment is performed by the end adjustment motor 7. The calculation method is: arctan[(m·Y_ACC - μ·mg) / (μ·m·Y_ACC)].

[0062] Vertical acceleration and deceleration, adjustment of the boom adjustment motor 2. When the vehicle detects a Z_Acc > 0 value, that is, the vehicle has a downward acceleration, within the time δt, the falling distance of the table body 6 is δd, Δd = V0·δt + Z_Acc·δt^2 / 2 (V0 is the vertical initial velocity when the fall occurs); the calculation method for the target adjustment angle of the boom adjustment motor 2 is: arcs in[(R·s in(90° - M1WP) - δd) / R], where R is the distance from the 4-boom joint axis.

[0063] Vertical acceleration and deceleration, the forearm adjustment motor 5 makes adjustments to keep the small table horizontal, and the forearm adjustment motor 5 makes compensation.

[0064] Furthermore, lateral-longitudinal-vertical-acceleration and deceleration compound adjustment is performed by the boom adjustment motor 2, the forearm adjustment motor 5, and the end adjustment motor 7:

[0065] When the vehicle is driving on a curved road with a tilt angle, that is, when X_ACC, Y_ACC, and Z_ACC are all non-zero, longitudinal acceleration and deceleration adjustment, lateral acceleration and deceleration adjustment, and vertical acceleration and deceleration will be performed simultaneously, and the three motors will adjust the target values simultaneously.

[0066] It can be understood that through the cooperation of the controller and sensors, the linkage control of the boom adjustment motor 2, the forearm adjustment motor 5, and the end adjustment motor 7 is carried out, and the adjustment situations for the position and angle of the table body 6 also include: when the vehicle accelerates during driving, longitudinal acceleration and deceleration adjustment of the table body 6, lateral acceleration and deceleration adjustment of the table body 6, vertical acceleration and deceleration adjustment of the table body 6, and the situation where lateral-longitudinal-vertical-acceleration and deceleration compound adjustment needs to be performed on the table body 6.

[0067] In this way, a stable load-carrying function is provided for users, the intelligent level and user experience are improved, and it can be retracted emergently when the vehicle collides to avoid harm to the occupants.
