Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent cockpit accessories, in particular to a table board for an intelligent cockpit and a adjusting method. BACKGROUND

[0002] With the continuous improvement of the intelligentization of automobiles and the comfort of the cockpit, the demand for temporary work and leisure scenarios in the vehicle by the driver and passengers is increasing. The use convenience, safety and stability of the table board for the cockpit, as an important auxiliary accessory, become key factors.

[0003] The manual folding table board is the current mainstream solution. Although it can realize the "expansion-folding" conversion through a hinge, the driver and passengers need to manually operate the force. Especially for children, the elderly and other groups, it is inconvenient to use. During the folding process, the weight of the table board and the friction of the hinge need to be overcome, which is not convenient to operate. Long-term manual operation can easily cause the hinge to wear and loosen, and problems such as "folding jam" and "one-sided sagging" may occur. From the aspects of synchronization and stability, the existing manual or semi-automatic table board generally lacks a "synchronous transmission mechanism". Most products use a single hinge or an asymmetric linkage structure. When folding, the forces on both sides are uneven, which can cause the "one side to reach first, and the other side to lag" deviation. In severe cases, it can cause the table board to tilt, and the notebook computers, water bottles and other items placed on it may fall over. Although some high-end vehicles try to add a single motor drive, they do not have a synchronous shaft. The motor power is only transmitted to one side, and the other side still relies on passive following. Long-term use can exacerbate the jam caused by the difference in wear between the two sides, and even cause the motor to overload and damage, resulting in high maintenance costs. In terms of safety protection, in the use scenario of the intelligent cockpit, children's accidental touch and forgotten items (such as mobile phones and tablets left on the table board) occur frequently. However, the traditional table board has neither a pressure detection function nor an emergency stop mechanism. When it is opened, the child's hand may be easily pinched if it is inserted into the gap between the table board and the seat. When it is closed, the items left in the load area may be damaged, and in severe cases, the structure of the table board may be deformed due to the obstruction of the items. In addition, the edges of the existing table board are designed as right angles, and no buffer structure is provided. If the driver and passengers accidentally collide during vehicle driving, they may be injured by the collision.

[0004] To solve the above problems, an intelligent cockpit table board that can automatically fold and adjust and has safety protection functions is needed, as well as a corresponding adjusting method. It is suitable for various vehicles equipped with intelligent cockpits, such as passenger cars and commercial vehicles, to provide convenient and safe temporary office, dining or item placement support for the driver and passengers.

Therefore, they should not be construed as limitations on this invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] Example 1: like Figures 1-12 As shown, a smart cockpit table 1 includes: Includes tabletop 1, mounting base 2, and folding mechanism 3; The tabletop 1 is connected to the mounting base 2 via the folding mechanism 3, the mounting base 2 is connected to the seat, and the tabletop 1 is mounted on the back of the seat via the mounting base 2; The table board 1 has an unfolded state and a folded state, when the table board 1 is in the unfolded state, it presents a horizontal state, the upward side as the bearing area can be used as the desktop for users to place articles, write or operate electronic equipment, etc., when the table board 1 is in the folded state, it presents a state closely combined with the chair back, the outward side as the back of the table board 1, the table board 1 is combined with the back of the seat, does not occupy extra space, is convenient for users to get in and out of the seat and move around the seat, the folding mechanism 3 can ensure that the table board 1 is stable and smooth during unfolding and folding, and can keep stable in the unfolded state and the folded state, and cannot shake or accidentally turn over, the mounting seat 2 is fixedly connected with the seat, can bear the weight of the table board 1 and the articles placed on the table board 1, and ensures the safety of the entire intelligent seat board 1 during use; The folding mechanism 3 comprises a hinge assembly 31, a driving motor 32 and a synchronous rotating shaft 33, the hinge assembly 31 and the driving motor 32 are both symmetrically provided with two groups, respectively corresponding to the folding execution part of the mechanism and the power output source, the synchronous rotating shaft 33 is connected with the output end of the hinge assembly 31 and the driving motor 32, the driving motor 32 is in driving connection with the hinge assembly 31 through the synchronous rotating shaft 33, forming a driving link of “driving motor 32-synchronous rotating shaft 33-hinge assembly 31”, so that the power of the driving motor 32 can be transmitted to the hinge assembly 31 through the synchronous rotating shaft 33.

[0025] The hinge assembly 31 comprises a first connecting rod 311 and a second connecting rod 312, one end of the first connecting rod 311 and the second connecting rod 312 is connected with the table board 1, the other end of the first connecting rod 311 and the second connecting rod 312 is connected with the mounting seat 2, the driving motor 32 changes the folding angle of the second connecting rod 312 through the synchronous rotating shaft 33, so that the table board 1 is converted between the open state and the closed state.

[0026] The first connecting rod 311 and the second connecting rod 312 are preferably metal materials, have good rigidity and durability, can bear the relatively large stress generated in the frequent folding process of the table board 1, and are not easy to deform or damage, the design of the hinge assembly 31 also fully considers the convenience of installation and maintenance, has a compact structure and occupies small space, is convenient for quick installation and disassembly on the table board 1 and the mounting seat 2, and greatly improves the practicability and maintainability of the product.

[0027] Further, in order to further improve the use experience of the intelligent table board 1, the table board 1 is also equipped with an intelligent control system connected with the driving motor 32. The user can control the unfolding and folding of the table board 1 through the control button on the seat. When the user presses the unfolding button, the intelligent control system receives the signal and immediately starts the driving motor 32. The synchronous shaft 33 drives the hinge assembly 31 to operate, so that the table board 1 is stably unfolded to the preset position. When the user presses the folding button or issues a folding voice command, the intelligent control system also responds quickly. The driving motor 32 on the other side operates in reverse, and the table board 1 is smoothly folded to the state of being attached to the back of the seat.

[0028] It needs to be further explained that the driving motors 32 on both sides will drive the synchronous shaft 33 to rotate in opposite directions according to different instructions (such as the two hinges 313 need to be folded outward synchronously when the table board 1 is opened, and folded inward synchronously when it is closed), and then drive the hinge assembly 31 to complete the corresponding folding action, realizing the opening and closing function of the mechanism. The symmetrical design of the hinge assembly 31 and the synchronous transmission structure of the synchronous shaft 33 can ensure the stability of the folding process and the consistency of the actions on both sides. When the table board 1 is unfolded or folded, the driving motor 32 on one side starts to drive the hinge assembly 31 to operate synchronously through the synchronous shaft 33, so that the table board 1 on both sides can be folded at the same speed and angle, ensuring the synchronization and stability of the table board 1 folding. This design not only avoids the jamming or distortion of the table board 1 during the folding process due to inconsistent movements on both sides, but also greatly improves the service life and reliability of the table board 1, ensuring that the table board 1 always remains stable during unfolding and folding.

[0029] The table board 1 includes a cover plate 11 and a bottom plate 12. The cover plate 11 and the bottom plate 12 are connected. The design of the cover plate 11 and the bottom plate 12 not only makes the assembly of the components of the table board 1 more convenient during manufacturing, but also allows the cover plate 11 and the bottom plate 12 to be easily separated for inspection, maintenance or replacement of parts during subsequent use, reducing maintenance costs. The cover plate 11 is provided with a guide groove 13 corresponding to the first connecting rod 311 and the second connecting rod 312. The guide groove 13 is provided with a guide groove seat 14. The guide groove seat 14 is connected with the cover plate 11. One end of the guide groove seat 14 is open. The other end of the guide groove seat 14 is shaped with the first connecting rod 311. The design of the guide groove seat 14 enables the first connecting rod 311 to move stably along the preset trajectory during the folding of the table board 1, effectively avoiding friction and collision between the first connecting rod 311, the second connecting rod 312 and the table board 1, and further improving the smoothness and stability of the folding of the table board 1. Secondly, the other end of the guide groove seat 14 is matched with the first connecting rod 311, which can make the guide groove seat 14 tightly fit the side surface of the first connecting rod 311 after the table plate 1 is closed. The matched structure not only reduces the shaking caused by the gap, but also realizes the integrity after closing through the contour matching, which improves the stability and appearance regularity of the mechanism. Meanwhile, the opening of the guide groove seat 14 can prevent the second connecting rod 312 from being rigidly resisted by the end of the guide groove seat 14 during the process of turning over the table plate 1. This design ingeniously uses the opening space to provide sufficient movement allowance for the second connecting rod 312, which ensures that the second connecting rod 312 can smoothly pass through the area of the guide groove seat 14 when the table plate 1 is turned over to different angles, and will not be jammed or abnormally worn due to space limitation, thereby ensuring the long-term stable and reliable operation of the whole table plate 1 turning mechanism.

[0030] Further, the cavity 15 is arranged between the cover plate 11 and the bottom plate 12, and the connecting plate 16 is arranged in the cavity 15. The arrangement of the cavity 15 not only provides a stable installation space for the connecting plate 16, but also makes the internal structure of the whole table plate 1 turning mechanism more compact and reasonable. The connecting plate 16 is connected with the cover plate 11 through bolts, which ensures the stability and reliability of the connection. One end of the first connecting rod 311 is hingedly connected with the connecting plate 16 through the first pin shaft 3111, and one end of the second connecting rod 312 is hingedly connected with the connecting plate 16 through the second pin shaft 3121. This hinged connection mode enables the connecting rod to rotate flexibly during movement, while ensuring the strength of the connection. The connecting plate 16 is preferably made of high-strength metal material, and has high hardness and wear resistance on the surface, which can withstand the force transmitted by the first connecting rod 311 and the second connecting rod 312 during long-term and frequent use without being easily deformed. The first pin shaft 3111 is further connected with the damper 3112, which is installed on the connecting plate 16. The arrangement of the damper 3112 further improves the stability of the table plate 1 turning. When the table plate 1 is turned over and subjected to external force, the damper 3112 can absorb part of the energy and slow down the turning speed of the table plate 1, thereby avoiding impact and noise and providing a more comfortable user experience. Moreover, the damping force of the damper 3112 can be accurately adjusted according to actual needs. In the production and manufacturing stage, by selecting dampers 3112 of different specifications or by making specific parameter settings to the dampers 3112, the table board 1 can exhibit just the right amount of resistance in different flipping scenarios, such as in an office scenario where the table board 1 needs to be flipped slowly and smoothly, the damping force of the damper 3112 is increased so that the table board 1 can be flipped at a slow and comfortable speed, avoiding the sliding of objects due to the flipping being too fast; and in some creative work scenarios where the angle of the table board 1 needs to be quickly adjusted, the damping force of the damper 3112 is appropriately reduced, allowing the user to easily and quickly change the position of the table board 1.

[0031] Furthermore, an anti-collision strip 17 is arranged between the cover plate 11 and the bottom plate 12, the anti-collision strip 17 is in clamped connection with the cover plate 11 and the bottom plate 12, and the anti-collision strip 17 is arranged in an arc shape along the outer edges of the cover plate 11 and the bottom plate 12. This arc-shaped anti-collision strip 17 can well fit the outer contours of the cover plate 11 and the bottom plate 12, and can play a comprehensive protection role. The anti-collision strip 17 is preferably made of a material with good elasticity and flexibility. When the table board 1 accidentally collides with other objects during the flipping process, the anti-collision strip 17 can effectively absorb and buffer the impact force generated by the collision, avoiding damage to the cover plate 11 and the bottom plate 12 due to direct collision, thereby further improving the reliability and stability of the entire table board 1 flipping mechanism.

[0032] In addition, the hinge assembly 31 further comprises a hinge 313 installed between the second connecting rod 312 and the mounting seat 2. The hinge 313 is installed on the mounting seat 2, and the mounting seat 2 is provided with a through hole 21 corresponding to the hinge 313. The hinge 313 is installed in the through hole 21, and the outer diameter of the hinge 313 is the same as the inner diameter of the through hole 21. The hinge 313 is installed on the mounting seat 2 (as a reference), and the other end is connected with the second connecting rod 312 through the clamping structure of “limiting protrusion 3131 + limiting groove 3122”, forming a “fixed end – movable end” linkage relationship. This design not only realizes the radial positioning of the two through clamping, but also provides guidance and constraint for the circumferential rotation of the second connecting rod 312. When the synchronous rotating shaft 33 rotates, the second connecting rod 312 rotates under the driving, and the cooperation of the limiting protrusion 3131 and the limiting groove 3122 can ensure the stability of the rotating track, avoiding the posture deviation of the second connecting rod 312 due to the axial movement or radial deflection of the synchronous rotating shaft 33, further improving the accuracy of the overall mechanism movement. The clamping structure transmits part of the radial force of the second connecting rod 312 to the hinge 313, and then disperses it to the mounting seat 2 through the hinge 313, avoiding the synchronous rotating shaft 33 bearing the radial load alone, and reducing the wear between the synchronous rotating shaft 33 and the shaft hole 3132; The hinge 313 is provided with a limiting protrusion 3131 on one side close to the second connecting rod 312, and the second connecting rod 312 is provided with a limiting groove 3122 corresponding to the limiting protrusion 3131, the limiting protrusion 3131 and the limiting groove 3122 are connected in a clamping manner, and the limiting groove 3122 cooperates with the limiting protrusion 3131 to realize the circumferential rotation of the second connecting rod 312, the clamping connection structure is simple, stable and reliable, and the limiting protrusion 3131 and the limiting groove 3122 are tightly matched during the overturning process of the table board 1, so that the rotation range of the second connecting rod 312 is accurately limited, and the over-rotation or rotation deviation of the second connecting rod 312 is prevented, thereby ensuring the accuracy and stability of the overturning action of the table board 1. Moreover, the design also has certain wear resistance, that is, even after long-term use and frequent table board 1 overturning operations, the cooperation between the limiting protrusion 3131 and the limiting groove 3122 is still tight, and the loosening or excessive wear will not occur, thereby further prolonging the service life of the hinge assembly 31 and ensuring the long-term stable and reliable operation of the entire table board 1 overturning mechanism.

[0033] Further, the hinge 313 is provided with a shaft hole 3132 at the center position and connected with the synchronous rotating shaft 33, the inner side wall of the shaft hole 3132 is shaped with the outer side wall of the synchronous rotating shaft 33, the connection point between the synchronous rotating shaft 33 and the hinge 313 is at the center of the hinge 313, which can ensure more balanced force transmission, reduce eccentric wear during rotation of the hinge 313, improve structural stability, and the contour shapes of the two are completely matched (for example, if the synchronous rotating shaft 33 is square, the shaft hole 3132 is also square; if the synchronous rotating shaft 33 has a key groove, the inner side of the shaft hole 3132 also has a matching protrusion, etc.), the design can realize rigid connection of the two, ensure that the synchronous rotating shaft 33 can directly drive the hinge 313 to move synchronously through the shaft hole 3132 during rotation, avoid relative slipping, ensure the accuracy of transmission, and is especially suitable for mechanical structures requiring synchronous action and preventing loosening. During long-term use, the high-precision shaped cooperation can also effectively reduce the problem of increased gap due to wear, further maintain the accuracy of transmission, and moreover, the shaped design of the shaft hole 3132 and the synchronous rotating shaft 33 makes it unnecessary to use additional fixing components such as bolts or clamps during connection, thereby simplifying the installation steps, reducing the installation difficulty, improving the production efficiency, and facilitating subsequent maintenance and replacement. When the synchronous rotating shaft 33 or the hinge 313 needs to be replaced due to damage, the synchronous rotating shaft 33 or the hinge 313 can be quickly and accurately disassembled and installed, thereby reducing the maintenance time and cost. Moreover, in a working scene with large vibration, such as during vehicle driving, the close profile fit can effectively resist the influence of vibration, ensuring stable and reliable transmission between the synchronous rotating shaft 33 and the hinge 313, and preventing relative displacement or slipping phenomenon due to vibration, thereby further ensuring the normal operation of the table board 1 overturning mechanism.

[0034] Furthermore, the center of the second connecting rod 312 is provided with a mounting groove 3123, which is arranged at the center of the second connecting rod 312 and corresponds to the center of the shaft hole 3132 of the hinge 313, so as to ensure the symmetry of the overall structure when the synchronous rotating shaft 33 passes through, avoid uneven stress or movement jamming caused by eccentric assembly, and provide a stable installation reference for the limiting piece 3124. The mounting groove 3123 is provided with the limiting piece 3124, which is sleeved on the synchronous rotating shaft 33 and is in interference fit between the limiting piece 3124 and the synchronous rotating shaft 33. The limiting piece 3124 is sleeved on the synchronous rotating shaft 33 and installed in the mounting groove 3123, which can limit the axial displacement of the second connecting rod 312 along the synchronous rotating shaft 33, prevent axial misalignment or collision with other components (such as the hinge 313) during movement, and ensure the stability of the relative position of the components. At the same time, the interference fit means that the inner diameter of the limiting piece 3124 is slightly smaller than the outer diameter of the synchronous rotating shaft 33, so that the two form a close clamping relationship after assembly, which can eliminate the looseness or shaking caused by the gap, ensure the transmission of force without lag, and enhance the impact resistance of the connection. Especially when rotating frequently or the load changes, it can reduce the relative wear between components and prolong the service life. The design is in resonance with the profiled shaft hole 3132 of the hinge 313: the former realizes synchronous transmission and axial constraint of the second connecting rod 312 through the limiting piece 3124 in interference fit, and the latter ensures the rigid synchronization of the hinge 313 and the rotating shaft through profiled fit. The two work together to ensure that the entire connecting rod mechanism (such as the second connecting rod 312, the hinge 313, etc.) can realize precise and coordinated linkage around the synchronous rotating shaft 33, avoiding the deviation of the overall action caused by slipping or displacement of a single component.

[0035] Embodiment 2: As shown in Figures 13-15 The application further provides an adjusting method for the table board for an intelligent cockpit according to Embodiment 1, which comprises the following steps: Step 1: instruction receiving and opening preparation: receiving the table board 1 opening instruction, the sensor collecting pressure data around the table board 1 and the back of the table board 1, and judging whether there is pressure; Step two: execute the table board opening action: if the pressure detection result of step one is no pressure, control the driving motor 32 to drive the synchronous shaft 33 to rotate, drive the first connecting rod 311 to rotate through the hinge 313, and the second connecting rod 312 synchronously changes the angle with the folding of the table board 1 until the table board 1 moves to the preset opening position and stops driving. Step three: instruction receiving and closing preparation: receive the table board 1 closing instruction, the sensor collects pressure data on the bearing area of the table board 1, and judges whether there is pressure on the bearing area. Step four: execute the table board closing action: if the pressure detection result of step three is no pressure, control the driving motor 32 on the other side to drive the synchronous shaft 33 to rotate in the opposite direction, drive the first connecting rod 311 to rotate in the opposite direction through the hinge 313, and the second connecting rod 312 synchronously changes the angle with the folding of the table board 1 until the table board 1 moves to the preset closing position and stops driving.

[0036] Among them, step one and step three respectively detect the pressure of the "surrounding area and back" before the table board is opened and the "bearing area" before it is closed, forming double safety protection: The pre-opening detection can avoid the table board from being turned over to pinch the human body (such as hands and legs) or collide with surrounding objects (such as seats and passenger personal belongings), prevent the mechanical structure from being overloaded, and prevent the table board from being closed forcibly when there are objects on it, causing the objects to fall or be damaged, or causing the driving mechanism to fail due to excessive load, thereby protecting the user's property and the equipment itself.

[0037] In addition, step two and step four drive the synchronous shaft 33 to rotate through the driving motor 32, and use the linkage structure of the hinge 313, the first connecting rod 311 and the second connecting rod 312 to realize the synchronous angle change of the table board folding. This transmission mode with the synchronous shaft as the core can ensure the stability of the table board during opening / closing, avoid jamming and skew caused by inconsistent action of each connecting rod, and finally accurately stop at the preset position (such as the horizontal use position and the vertical storage position), thereby improving the user experience.

[0038] Further, in steps one to four, sensors are installed on the cover plate 11, the bottom plate 12 and the anti-collision strip 17. If the sensor detects pressure during the opening or closing of the table board, the driving motor 32 will stop working, thereby stopping the action of the table board and issuing a voice prompt. The distribution of sensors on the cover plate 11, the bottom plate 12 and the anti-collision strip 17 means that the front (bearing area), back (side opposite to the mounting seat or cabin component) and edge (position prone to collision) of the table board are all within the monitoring range. This monitoring coverage avoids safety blind spots, and whether the back of the table board touches obstacles when opening, the front presses objects when closing, or the edge collides with the human body or objects during movement, can be sensed in time. And, different from the "action before detection" in steps one and three, the real-time monitoring during the "opening or closing process" is emphasized, and the safety protection is extended from the "pre-judgment" to the "dynamic execution" stage. Once the sensor detects pressure during movement (such as user mis-touch, accidental entanglement of objects), the driving motor 32 stops working immediately to avoid the continuous effect of force causing pinching, equipment damage or object falling, realizing the "touch and stop" emergency protection and greatly improving the operation safety.

[0039] Further, in step four, before the table board 1 is completely closed, that is, when the table board distance from the completely closed gap is ≤10mm, the sensor will again detect the pressure of the table board 1 bearing area and the surrounding area of the table board 1. If pressure is detected, the driving motor 32 stops working and the table board 1 stops closing action; At this stage, the gap between the table board and the seat back gradually narrows, and if there are objects left out or human body parts misextended, it is easy to cause extrusion; At the same time, if small objects are left in the bearing area, they may be damaged due to stress concentration before complete closure; The second detection can intercept such risks at the last stage to avoid accidents when "almost completed". When the table board is completely closed, the components (such as hinges, connecting rods, synchronous shafts) are usually in a "locked position" under stress balance. If the closure is forced due to the existence of pressure obstacles at this time, it may cause structural overload (such as connecting rod deformation, motor locked rotor). The second detection at the end can stop in time before locking to reduce the damage of mechanical parts caused by hard impact and prolong the service life of the equipment.

[0040] In addition, when the seat back adjustment instruction is detected, the sensor detects the pressure of the table board 1 bearing area. If the table board bearing area load is not zero, stop the seat back adjustment action and issue a voice prompt. The detection result of "non-zero load" in the table board bearing area directly points to the potential risk that "objects may be affected by the backrest adjustment" - for example, laptops, water bottles and other objects may be extruded due to the proximity of the backrest, or dropped due to the imbalance of the table board stress caused by the change of the cabin space. At this time, stop the seat adjustment and prompt, which not only protects the safety of the loaded objects, but also avoids the secondary harm caused by the falling of objects (such as liquid spillage damaging cabin equipment, hard objects injuring passengers).

[0041] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
