Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a table top posture change control system, a control method and a table top. Background Art

[0002] With the continuous development of automobile technology, the functionality of automobiles is becoming more and more diversified. In order to facilitate passengers to place items or work during leisure time, some car seats are equipped with small tables. The extension and storage of the small tables are generally achieved by installing a drive motor on the inner side of the back of the table base. When it is needed, the drive motor drives the hinge arm to drive the table body that stays in the main base to extend outward to a fixed angle and then stop; when it is not needed, the drive motor installed on the inner side of the back of the table base rotates in the opposite direction, and drives the table shell body to flip in the opposite direction at a fixed angle through the combined hinge, and then retracts to stay inside the table base. This control method for the extension and storage of the small table ensures that once the small table is extended to the use position, its angle position relative to the back of the seat back will not change. When the passenger adjusts the backrest according to the comfort level, it is easy to cause the table board body (small table board) installed on the back of the seat back to lose balance, causing the items on the table to shake or even slide off; especially when the car encounters climbing or downhill road conditions during driving, the table board will also lose balance, causing the items on the table to slide off and cannot be used normally. Summary of the invention

[0003] 1. Technical problem to be solved by the invention

[0004] In order to solve the technical problem that the table top surface cannot be kept in a balanced state when affected by external factors, the present invention provides a table top posture change control system, a control method and a table top, which can monitor the state of the table top in real time, so that the table top surface can always remain in a balanced state, thereby meeting the use of the table top in different states when extended.

[0005] 2. Technical solution

[0006] To solve the above problems, the technical solution provided by the present invention is:

[0007] The present invention provides a table top posture change control system, comprising: a gyroscope gravity sensor module arranged in a table top shell; a hinge assembly, used to connect the table top shell and the table top base; a drive motor, the drive motor is transmission-connected to the hinge assembly; a motor drive control module, used to control the drive motor, the gyroscope gravity sensor module is electrically connected to the motor drive control module; and a controller, the controller is electrically connected to the gyroscope gravity sensor module and the motor drive control module respectively.

[0008] In this embodiment, the table top includes a table top shell and a table top base, and the table top base is arranged in the seat back. When the table top surface on the table top shell needs to be unfolded, the controller is started, and the controller sends a start signal instruction to the motor drive control module and the gyroscope gravity sensor module. At this time, the gyroscope gravity sensor module that obtains the signal instruction begins to detect the overall posture change of the table top shell, and converts the detected posture change into corresponding electrical parameters; at the same time, the motor drive control module that obtains the signal instruction drives and controls the drive motor to rotate forward, and since the hinge assembly is connected with the output shaft of the drive motor, it is used to drive the table top shell to rotate relative to the table top base; therefore, driven by the drive motor, the hinge assembly rotates clockwise relative to the table top shell, and at the same time, the rotational movement causes the hinge assembly to move upward relative to the table top base, and the table top shell moves outward relative to the table top base under the drive of the hinge assembly. When the table top on the table shell is adjusted to move to a horizontal position, the gyroscope gravity sensor module in the table shell detects a signal of the horizontal position and converts the signal into corresponding electrical parameters. After the controller obtains the signal, it controls the gyroscope gravity sensor module to transmit the electrical parameters to the motor drive control module. The motor drive control module controls the drive motor to stop running. At this time, the table top on the table shell has been fully unfolded and is in a horizontal position, and the table top on the table shell can be used by passengers; when the seat back angle changes or the body of the car changes ups and downs, the overall posture of the table shell will change. At this time, the gyroscope gravity sensor module converts the detected posture changes into corresponding electrical parameters. After the controller obtains the signal, it controls the gyroscope gravity sensor module to input the electrical parameters into the motor drive control module. Then, the motor drive control module quickly corrects the operating state of the drive motor according to the electrical parameters transmitted by the gyroscope gravity sensor module until the table top on the table shell is in a horizontal position and stops. It can be seen from this that the setting of the gyroscope gravity sensing module can detect the front and rear horizontal posture of the table top on the table top shell in real time when the table top is extended for use, and correct the horizontal angle of the table top in real time, so that the table top on the table top shell always remains horizontal front and back, completely overcoming the current situation where the seat back cannot be used normally due to the front and rear angle adjustment or the vehicle loses balance when climbing or descending hills, thereby ensuring the practicality and intelligence of the table top behind the seat.

[0011] Optionally, the gyroscope gravity sensor module is arranged in a middle position inside the table top shell, and the gyroscope gravity sensor module is electrically connected to the motor drive control module.

[0012] Optionally, the gyroscope gravity sensing module includes a gyroscope and a gravity sensor, and the gyroscope and the gravity sensor are electrically connected to the controller respectively.

[0013] Optionally, there are two drive motors, each drive motor corresponds to a motor drive control module, the motor drive control modules are respectively arranged on both sides of the gyroscope gravity sensor module, and the drive motor is arranged below the motor drive control module.

[0014] Optionally, the controller includes a control touch screen and a controller module, the control touch screen is electrically connected to the controller module, the control touch screen is arranged at the end edge of the table top base, the controller module is arranged in the table top shell, and the controller module is electrically connected to the gyroscope gravity sensor module and the motor drive control module respectively.

[0015] Optionally, a limit device is also included, which includes a position sensor and a magnetic protrusion. The position sensor is arranged corresponding to the magnetic protrusion, and the position sensor is electrically connected to the controller. When the table top shell is retracted into the table top base, the magnetic protrusion triggers the position sensor, and the controller controls the motor drive control module, and the motor drive control module controls the drive motor to stop running.

[0016] The present invention also provides a control method of a table top posture change control system, which is used to control the table top posture change control system described above, and comprises the following steps:

[0017] Step 1: The gyroscope gravity sensor module sends angle parameter information of the table top posture change to the controller;

[0018] Step 2: The controller receives the angle parameter information and determines whether the table top is in a horizontal position;

[0019] If the table surface is not in a horizontal position, the controller controls the motor drive control module to control the running state of the drive motor according to the parameters input by the gyroscope gravity sensor module;

[0020] If the gyro gravity sensor module detects that the table top is in a horizontal position, the motor drive control module controls the drive motor to stop running.

[0021] In addition, the present invention also provides a table top, including: a table top shell and a table top base, and the table top shell rotates relative to the table top base under the control of the above-mentioned table top posture change control system.

[0022] 3. Beneficial effects

[0023] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0024] (1) The table top posture change control system proposed in the embodiment of the present application, due to the setting of the gyroscope gravity sensing module in the table top shell, can detect the front and rear horizontal posture of the table top surface on the table top shell in real time when the table top surface is extended for use, and correct the horizontal angle of the table top surface in real time, so that the table top surface on the table top shell always remains horizontal front and back, completely overcoming the current situation where the vehicle cannot be used normally due to the front and rear angle adjustment of the seat back or the loss of balance when driving on climbing or downhill roads, thereby ensuring the practicality and intelligence of the table top behind the seat.

[0025] (2) The control method of the table top posture change control system proposed in the embodiment of the present application can effectively control the table top posture change control system when the table top is unfolded, detect the front and rear horizontal posture of the table top in real time, and correct the horizontal angle of the table top surface in real time, so that the table top surface on the table top shell always remains horizontal front and rear, completely overcoming the current situation where the vehicle cannot be used normally due to loss of balance when adjusting the front and rear angle of the seat back or when driving on climbing or downhill roads, thereby ensuring the practicality and intelligence of the table top behind the seat.

[0026] (3) The table top proposed in the embodiment of the present application is arranged inside the seat back. Since a table top posture change control system is arranged inside the table top, the table top posture change control system can detect the front and rear horizontal posture of the table top in real time, and correct the horizontal angle of the table top shell in real time, so that the table top surface of the table top shell always remains horizontal front and rear, which completely overcomes the current situation where the seat table top cannot be used normally due to loss of balance when adjusting the front and rear angle of the seat back or when driving on climbing or downhill roads, thereby ensuring the practicality and intelligence of the seat table top.

[0035] Example 1

[0036] Combined with Figure 1-6 The present embodiment provides a table top posture change control system, including: a gyroscope gravity sensor module 14 arranged in the table top shell 2; a hinge assembly 1, used to connect the table top shell 2 and the table top base 3; a drive motor 4, the drive motor 4 is transmission-connected to the hinge assembly 1; a motor drive control module 5, used to control the drive motor 4, the gyroscope gravity sensor module 14 is electrically connected to the motor drive control module 5; a controller, the controller is electrically connected to the gyroscope gravity sensor module 14 and the motor drive control module 5 respectively.

[0037] In this embodiment, the table top includes a table top shell 2 and a table top base 3, and the table top base 3 is arranged in the seat back. When the table top surface on the table top shell 2 needs to be unfolded, the controller is started, and the controller sends a start signal command to the motor drive control module 5 and the gyroscope gravity sensor module 14. At this time, the gyroscope gravity sensor module 14 that obtains the signal command begins to detect the overall posture change of the table top table top shell 2, and converts the detected posture change into corresponding electrical parameters; at the same time, the motor drive control module 5 that obtains the signal command drives and controls the drive motor 4 to rotate forward, because the hinge assembly 1 is connected with the output shaft of the drive motor 4, it is used to drive the table top shell 2 to rotate relative to the table top base 3; therefore, driven by the drive motor 4, the hinge assembly 1 rotates clockwise relative to the table top shell 2, and at the same time, the rotational movement makes the hinge assembly 1 move upward relative to the table top base 3, and the table top shell 2 moves outward relative to the table top base 3 under the drive of the hinge assembly 1. When the table top on the table top shell 2 is adjusted to move to a horizontal position, the gyroscope gravity sensor module 14 in the table top shell 2 detects a signal of the horizontal position and converts the signal into corresponding electrical parameters. After the controller obtains the signal, it controls the gyroscope gravity sensor module 14 to transmit the electrical parameters to the motor drive control module 5. The motor drive control module 5 controls the drive motor 4 to stop running. At this time, the table top on the table top shell 2 has been fully unfolded and is in a horizontal position, and the table top on the table top shell 2 can be used by passengers; when the seat back angle changes or the body of the vehicle fluctuates, the overall posture of the table top shell 2 will change. At this time, the gyroscope gravity sensor module 14 converts the detected posture changes into corresponding electrical parameters. After the controller obtains the signal, it controls the gyroscope gravity sensor module 14 to input the electrical parameters into the motor drive control module 5. Then, the motor drive control module 5 quickly corrects the operating state of the drive motor 4 according to the electrical parameters transmitted by the gyroscope gravity sensor module 14 until the table top on the table top shell 2 stops when it is in a horizontal position. It can be seen from this that the setting of the gyroscope gravity sensing module can detect the front and rear horizontal posture of the table top on the table top shell 2 in real time when the table top shell 2 is extended for use, and correct the horizontal angle of the table top in real time, so that the table top on the table top shell 2 always remains horizontal front and back, completely overcoming the current situation where the vehicle cannot be used normally due to the front and rear angle adjustment of the seat back or the loss of balance when driving on climbing or downhill roads, thereby ensuring the practicality and intelligence of the table top behind the seat.

[0038] Example 2

[0039] Combined with Figure 1-6, the table top posture change control system of this embodiment, compared with the technical solution of embodiment 1, one end of the hinge assembly 1 is rotatably fixed in the table top shell 2, and the other end of the hinge assembly 1 is rotatably fixed on the table top base 3. The hinge assembly 1 has two groups, and the two ends of the hinge assembly 1 are rotatably fixed in the table top shell 2 and on the table top base 3 respectively. This arrangement enables the table top shell 2 and the table top base 3 to be connected through the hinge assembly 1. When the driving motor 4 is running, the two groups of hinge assemblies 1 are driven by the driving motor 4 to synchronously drive the table top shell 2 to rotate relative to the table top base 3.

[0040] In actual use, hinge bases 23 are respectively provided on both sides of the table base 3, and the hinge assembly 1 is rotatably connected to the hinge base 23 through a connecting structure. This arrangement can ensure that the hinge assembly 1 is stably arranged on the table base 3.

[0041] Example 3

[0042] Combined with Figure 1-6 , the table top posture change control system of this embodiment, compared with the technical solution of embodiment 2, the hinge assembly 1 includes an active connecting rod 6 and a driven connecting rod 7, the two ends of the active connecting rod 6 are respectively rotated and fixed in the table top shell 2 and the table top base 3, and the two ends of the driven connecting rod 7 are respectively rotated and fixed in the table top shell 2 and the table top base 3.

[0043] The two ends of the active connecting rod 6 are respectively rotated and fixed in the table top shell 2 and on the table top base 3, and the two ends of the driven connecting rod 7 are respectively rotated and fixed in the table top shell 2 and on the table top base 3. When the driving motor 4 is running, the driving motor 4 drives the active connecting rod 6 and the driven connecting rod 7 to rotate synchronously, and drives the table top shell 2 to rotate relative to the table top base 3. When the table top shell 2 rotates and extends relative to the table top base 3, the active connecting rod 6 is located above the driven connecting rod 7.

[0044] In actual use, the first group of bearing sleeves and the second group of bearing sleeves are sequentially provided on both sides of the table board shell 2 along the length direction of the table board shell 2, the first group of bearing sleeves include a first bearing sleeve 9 and a second bearing sleeve 10 arranged oppositely, the second group of bearing sleeves include a third bearing sleeve 11 and a fourth bearing sleeve 12 arranged oppositely, the output shaft 13 of the drive motor 4 is movably passed through the third bearing sleeve 11 and the fourth bearing sleeve 12 in sequence, one end of the active connecting rod 6 is spline-engaged with the output shaft 13 of the drive motor 4, and is located between the third bearing sleeve 11 and the fourth bearing sleeve 12; the first bearing sleeve 9 and the second bearing sleeve 10 arranged oppositely are connected by a pin shaft, one end of the driven connecting rod 7 is rotatably connected to the pin shaft, and is located between the first bearing sleeve 9 and the second bearing sleeve 10. One end of the active connecting rod 6 is spline-engaged with the output shaft 13 of the drive motor 4. This arrangement allows the active connecting rod 6 to rotate and move radially around the axes of the third bearing sleeve 11 and the fourth bearing sleeve 12 under the drive of the drive motor 4 when the drive motor 4 is running. The driven connecting rod 7 moves synchronously radially around the bearings of the first bearing sleeve 9 and the second bearing sleeve 10 as the active connecting rod 6 rotates, driving the table top shell 2 to rotate relative to the table top base 3.

[0045] In actual use, the driven connecting rod 7 has a hollow cavity, and a transmission harness 8 is inserted into the hollow cavity of the driven connecting rod 7. The transmission harness 8 passes through the hollow cavity of the driven connecting rod 7 in the hinge assembly 1 from the table base 3 and enters the table shell 2. This setting can protect the concealment of the power cord and the safety during dynamic rotation.

[0046] Example 4

[0047] Combined with Figure 1-6 , the table top attitude change control system of this embodiment, compared with the technical solution of embodiment 1, the gyroscope gravity sensor module 14 is arranged in the middle position of the table top shell 2, and the gyroscope gravity sensor module 14 is electrically connected to the motor drive control module 5. The gyroscope gravity sensor module 14 is arranged in the middle position of the table top shell 2, and this setting enables the gyroscope gravity sensor module 14 to quickly sense the attitude change of the table top shell 2, and transmit the signal to the motor drive control module 5, thereby controlling and correcting the operating state of the drive motor 4, so that the table top surface on the table top shell 2 is always in a horizontal position.

[0048] Example 5

[0049] Combined with Figure 1-6 Compared with the technical solution of Example 4, the table top posture change control system of this embodiment is that the gyroscope gravity sensor module 14 includes a gyroscope and a gravity sensor, and the gyroscope and the gravity sensor are electrically connected to the controller respectively.

[0050] When the posture of the table shell 2 of the table top changes, the gyroscope can quickly obtain the angle change data of the table shell 2, and quickly convert the angle change data into corresponding electrical parameters. After the controller obtains the signal, it controls the gyroscope gravity sensor module 14 to input the electrical parameters to the motor drive control module 5 to correct the motor posture; at the same time, the built-in gravity sensor using the piezoelectric effect also detects the posture change of the table shell 2 together with the gyroscope to detect whether the table top has moved to a horizontal position. Once the table shell 2 is in a horizontal position, the controller obtains the signal and controls the gyroscope gravity sensor module 14 to transmit its signal to the motor drive control module 5 to control the drive motor 4 to stop running.

[0051] Example 6

[0052] Combined with Figure 1-6 Compared with the technical solution of Example 1, the table top posture change control system of this embodiment has two drive motors 4, each drive motor 4 corresponds to a motor drive control module 5, and the motor drive control modules 5 are respectively arranged on both sides of the gyroscope gravity sensor module 14, and the drive motor 4 is arranged below the motor drive control module 5.

[0053] This arrangement makes the structure of the entire table top more compact and can ensure signal transmission between the gyroscope gravity sensor module 14 and the motor drive control module 5 and the drive motor 4 .

[0054] In actual use, the drive motor 4 is a stepper motor. There are two drive motors 4, which are arranged on the alloy frame 15 through a fixing frame, and the two drive motors 4 are symmetrically installed about the vertical axis center line of the alloy frame 15, which can enhance the stability of the drive motor 4 when working.

[0055] The two side walls of the alloy skeleton 15 are provided with multiple through holes, and the output shaft 13 of the driving motor 4 is sequentially penetrated through the third bearing sleeve 11, the through hole and the fourth bearing sleeve 12, one end of the active connecting rod 6 is arranged between the side wall of the alloy skeleton 15 and the fourth bearing sleeve 12, and passes through the first bearing sleeve 9, the through hole and the second bearing sleeve 10 in sequence through a pin shaft, and one end of the driven connecting rod 7 is arranged between the alloy skeleton 15 and the second bearing sleeve 10. When the driving motor 4 rotates, the driving motor 4 can drive the alloy skeleton 15 to make radial movement around the axes of the relatively arranged third bearing sleeve 11 and the fourth bearing sleeve 12 and the relatively arranged first bearing sleeve 9 and the second bearing sleeve 10, so that the active connecting rod 6 and the driven connecting rod 7 rotate synchronously, driving the table board to rotate relative to the table board base 3.

[0056] Example 7

[0057] Combined with Figure 1-6Compared with the technical solution of Example 1, the table top posture change control system of this embodiment comprises a controller including a control touch screen 16 and a controller module 17, wherein the control touch screen 16 is electrically connected to the controller module 17, the control touch screen 16 is arranged at the end edge of the table top base 3, the controller module 17 is arranged in the table top shell 2, and the controller module 17 is electrically connected to the gyroscope gravity sensor module 14 and the motor drive control module 5 respectively.

[0058] The control touch screen 16 is provided with an on and off icon. The user touches the on and off icon on the control touch screen 16 to transmit the on and off signal instructions to the gyroscope gravity sensor module 14 and the motor drive control module 5 respectively through the controller module 17. The motor drive control module 5 drives the motor 4 to operate, and the gyroscope gravity sensor module 14 detects the posture changes of the table top in real time according to the signal.

[0059] Example 8

[0060] Combined with Figure 1-6 Compared with the technical solution of Example 1, the table top posture change control system of this embodiment further includes a limit device, which includes a position sensor and a magnetic protrusion (not shown in the figure). The position sensor is correspondingly arranged to the magnetic protrusion, and the position sensor is electrically connected to the motor drive control module 5. When the table top shell is retracted into the table top base, the magnetic protrusion triggers the position sensor, and the motor drive control module 5 controls the drive motor 4 to stop running.

[0061] In actual use, the position sensor is arranged in the table top shell 2, and a position detection disk is provided on the output shaft 13 of the driving motor 4 near one end of the hinge assembly 1, and the magnetic piece protrusion is arranged on the position detection disk. The position sensor is arranged corresponding to the magnetic piece protrusion. When the table top shell 2 is fully retracted into the table top base 3, the magnetic protrusion triggers the position sensor. At this time, the position sensor generates a trigger signal, and the controller obtains the trigger signal and inputs the trigger signal to the motor drive control module 5. The motor drive control module 5 controls the driving motor 4 to stop running and maintain the standby state of this action. When the start button of the controller is started again, the trigger signal of the position sensor can be released. This setting can ensure that the table top shell 2 is accurately retracted into the table top base 3.

[0062] Example 9

[0063] Combined with Figure 1-6 This embodiment provides a control method for a table top posture change control system, which is used to control the table top posture change control system described in any one of the technical solutions of Embodiments 1 to 8, and includes the following steps:

[0064] Step 1: The gyro gravity sensor module 14 sends the angle parameter information of the table surface posture change to the controller;

[0065] Step 2: The controller receives the angle parameter information and determines whether the table top is in a horizontal position;

[0066] If the table surface is not in a horizontal position, the controller controls the motor drive control module 5 to control the operation state of the drive motor 4 according to the parameters input by the gyroscope gravity sensor module 14;

[0067] If the gyro gravity sensor module 14 detects that the table top is in a horizontal position, the motor drive control module 5 controls the drive motor 4 to stop running.

[0068] In actual use, when the table top needs to be unfolded, the user touches the start icon of the touch control screen 16 of the controller to start the controller module 17. The controller module 17 releases the trigger signal of the position sensor and synchronously switches the controller module 17 to send a start signal instruction to the motor drive control module 5 and the gyroscope gravity sensor module 14. At this time, the gyroscope gravity sensor module 14 that obtains the signal instruction begins to detect the overall posture change of the table top shell 2, and converts the posture change of the table top shell 2 detected by it into corresponding electrical parameters; at the same time, the motor drive control module 5 that obtains the signal instruction drives and controls the drive motor 4 to rotate forward. Since the hinge assembly 1 is connected with the output shaft of the drive motor 4, it is used to drive the table top shell 2 to rotate relative to the table top base 3; therefore, driven by the drive motor 4, the hinge assembly 1 rotates clockwise relative to the table top shell 2, and at the same time, the rotational motion causes the hinge assembly 1 to move upward relative to the table top base 3, and the table top shell 2 extends outward relative to the table top base 3 driven by the hinge assembly 1. When the table top of the table top shell 2 is adjusted to move to a horizontal position, the gyroscope gravity sensor module 14 in the table top shell 2 detects a signal that the table top of the table top shell 2 is in a horizontal position, and converts the signal into corresponding electrical parameters. After the controller obtains the signal, it controls the gyroscope gravity sensor module 14 to transmit the electrical parameters to the motor drive control module 5. The motor drive control module 5 controls the drive motor 4 to stop running. At this time, the table top of the table top shell 2 has been fully unfolded and is in a horizontal position, and the table top can be used by passengers; when the seat back angle changes or the body of the car is moved When the value of volts changes, the overall posture of the table shell 2 will change. At this time, the gyroscope gravity sensor module 14 converts the detected posture changes into corresponding electrical parameters. The controller obtains the signal to control the gyroscope gravity sensor module 14 to input the electrical parameters into the motor drive control module 5. Then, the motor drive control module 5 accurately and quickly corrects the operating state of the drive motor 4 according to the electrical parameters transmitted by the gyroscope gravity sensor module 14, until the gyroscope gravity sensor module 14 detects that the table top is in a horizontal position, and the motor drive control module 5 controls the drive motor 4 to stop.

[0069] When the table top is not needed, the user touches the close icon on the touch control screen 16 of the controller to start the controller module 17, and the controller module 17 sends a close signal instruction to the motor drive control module 5 and the gyroscope gravity sensor module 14. At this time, the gyroscope gravity sensor module 14 that receives the signal instruction stops detecting the overall posture change of the table top shell 2. At the same time, the motor drive control module 5 that receives the signal instruction controls the drive motor 4 to reverse. Since the hinge assembly 1 is connected with the output shaft of the drive motor 4 to drive the table top shell 2 to rotate relative to the table top base 3; therefore, driven by the drive motor 4 The hinge assembly 1 rotates counterclockwise relative to the table top shell 2, and the rotational movement causes the hinge assembly 1 to move downward relative to the table top base 3. Driven by the hinge assembly 1, the table top shell 2 moves inward relative to the table top base 3 until the table top shell 2 is retracted and inside the table top base 3. The magnetic protrusion triggers the position sensor. At this time, the position sensor generates a trigger signal. The controller obtains the trigger signal and inputs the trigger signal to the motor drive control module 5. The motor drive control module 5 controls the drive motor 4 to stop running and maintain the standby state of this action. The entire action stops.

[0070] It can be seen from this that this control method can effectively control the table top posture change control system when the table top is unfolded, detect the front and rear horizontal posture of the table top in real time, and correct the horizontal angle of the table top surface in real time, so that the table top surface on the table top shell 2 always remains horizontal front and back, completely overcoming the current situation where the vehicle cannot be used normally due to loss of balance when adjusting the front and rear angle of the seat back or when driving on climbing or downhill roads, thereby ensuring the practicality and intelligence of the table top behind the seat.
