[0081] Combined Figures 1 to 18 As shown, an in - vehicle table storage mechanism includes a mounting frame 1, a table board assembly 2, a moving assembly 3, a clamping plate assembly 4, and an unlocking assembly 5.

[0082] The table board assembly 2 is slidably disposed on the mounting frame 1; the moving assembly 3 is slidably disposed on the mounting frame 1, the table board assembly 2 is rotatably disposed on the moving assembly 3, and the moving assembly 3 is used to drive the table board assembly 2 to move outside the mounting frame 1; the clamping plate assembly 4 is clamped on the mounting frame 1 and is used to restrict the table board assembly 2 and the moving assembly 3; the unlocking assembly 5 is disposed on one side of the clamping plate assembly 4, the unlocking assembly 5 is in contact with the moving assembly 3, and the unlocking assembly 5 is used to restrict the movement of the moving assembly 3.

[0083] Among them, by slidably arranging the moving assembly 3 inside the mounting frame 1, under the action of the moving assembly 3, the table board assembly 2 can be automatically slid out from the inside of the mounting frame 1 to the external use position or retracted to the internal storage position. By rotatably arranging the table board assembly 2 on the moving assembly 3, under the action of the table board assembly 2, when the table board assembly 2 moves outside the mounting frame 1, the table board assembly 2 can be unfolded for passengers to use. When the table board assembly 2 needs to be stored inside the mounting frame 1, it can also be retracted, and at the same time, the angle of the table board assembly 2 can be adjusted according to the corresponding situation. By arranging the clamping plate assembly 4 on the mounting frame 1, under the action of the clamping plate assembly 4, the movement of the moving assembly 3 can be restricted, ensuring that the table board assembly 2 is fixed at a predetermined position in both the storage and use states, and at the same time, it can also restrict the moving assembly 3 from sliding along the tracks of the mounting frame 1 and the clamping plate assembly 4 to ensure that the moving assembly 3 does not get stuck during the sliding process. By arranging the unlocking assembly 5 on one side of the clamping plate assembly 4 and the unlocking assembly 5 being in contact with the moving assembly 3, under the action of the unlocking assembly 5, according to the needs of passengers, the restriction on the moving assembly 3 can be released, so that the moving assembly 3 can automatically move the table board assembly 2 from inside the mounting frame 1 to the outside.

[0084] The working principle of this device is as follows:

[0085] When the table board assembly 2 needs to be used, only need to press the unlocking assembly 5 to release the restriction on the moving assembly 3. The moving assembly 3 can drive the table board assembly 2. Since the moving assembly 3 and the table board assembly 2 are restricted by the clamping plate assembly 4, the moving assembly 3 can only drive the table board assembly 2 to move along the track of the mounting frame 1 until the moving assembly 3 drives the table board assembly 2 outside the mounting frame 1 and rotates the table board assembly 2 according to the corresponding needs, then the table board assembly 2 can be unfolded for use.

[0086] CombinedFigure 16 As shown, a guide rail frame 11 is horizontally arranged at the center of the installation frame 1, and the moving component 3 is slidably arranged on the guide rail frame 11. The guide rail frame 11 provides an accurate sliding path for the moving component 3, ensuring that it will not deviate from the predetermined track during the sliding process. This helps to maintain the stability and reliability of the table board component 2. The guide rail frame usually adopts low-friction materials or designs, which can significantly reduce the friction force of the moving component 3 during the sliding process and make the sliding smoother.

[0087] Combined with Figure 6 and Figure 10 As shown, the moving component 3 includes: a base 31, a first rotating arm 32, a rotating bracket 33, a strengthening support frame 34, a first driving member 35 and a spring assembly 36. A groove 311 is formed in the base 31, and the guide rail frame 11 is slidably embedded in the groove 311; the first rotating arm 32 is rotatably arranged on the base 31; the rotating bracket 33 is rotatably arranged on the first rotating arm 32; the strengthening support frame 34 is rotatably arranged between the first rotating arm 32 and the rotating bracket 33; the first driving member 35 is arranged on the lower side of one side of the base 31; the spring assembly 36 is arranged in the installation frame 1 and is connected to the base 31; the table board component 2 is rotatably arranged on the rotating bracket 33. The first driving member 35 is a micro gear motor, and a rack 12 is arranged along the length direction on one side in the installation frame 1, and the output end of the first driving member 35 is engaged with the rack 12.

[0088] Among them, the base 31 serves as the foundation of the entire mobile component. It not only bears all other components but also realizes the sliding function of the component in the horizontal direction through the cooperation of the groove 311 on it and the guide rail frame 11. This design enables the tabletop to move linearly along a predetermined path. The first rotating arm 32 is installed on the base 31 and can rotate around a fixed axis, which provides the tabletop component with rotational freedom, allowing the user to adjust the angle or direction of the tabletop as needed. The rotating bracket 33 is fixed on the first rotating arm 32, further increasing the flexibility of the tabletop component. By rotating the rotating bracket, the angle adjustment of the tabletop in the vertical plane can be achieved to meet the requirements in different usage scenarios. The strengthening support frame 34 is located between the first rotating arm 32 and the rotating bracket 33, which is used to enhance the structural stability and load-bearing capacity, ensuring that the structure will not deform or be damaged due to excessive load when adjusting the position of the tabletop. At the same time, when the strengthening support frame 34, the first rotating arm 32, and the rotating bracket 33 act together, a triangular structure can be formed after unfolding to withstand the external pressure on the tabletop component 2 during the use of the tabletop component 2, so as to ensure the structural stability during the use of the tabletop component 2. The first driving member 35 is in the form of a micro gear motor and is installed on one side below the base 31. Its output shaft meshes with the rack 12 arranged along the length direction inside the mounting frame 1. When the motor is started, through the interaction between the gear and the rack, the base 31 and all components on it can be driven to move precisely linearly along the direction of the guide rail frame 11. This design not only saves space but also improves the response speed and control accuracy of the system. The coil spring assembly 36 is arranged in the mounting frame 1 and is connected to the base 31. Its main function is to help the tabletop component 2 achieve a certain automatic reset effect when being pushed into the mounting frame 1 when the tabletop component 2 is stored in the mounting frame 1, greatly saving the thrust and ensuring that the tabletop component 2 can move smoothly into the mounting frame 1. The tabletop component 2 is finally installed on the rotating bracket 33. Through the coordinated action of the above-mentioned components, precise position adjustment can be achieved in multiple degrees of freedom to adapt to different usage environments and operation requirements.

[0089] When it is necessary to open the tabletop assembly 2 for use, press the unlocking assembly 5 to release the restriction on the moving assembly 3. Then the moving assembly 3 can drive the tabletop assembly 2 to move. At the same time, a start signal is sent to the first driving member 35, and the micro gear motor starts. Its output shaft meshes with the rack 12, driving the base 31 and all components thereon to move linearly along the direction of the guide rail frame 11 until the tabletop assembly 2 is completely outside the installation frame 1. By manually rotating the rotation angle of the first rotating arm 32, the horizontal direction angle of the tabletop assembly 2 can be changed. The rotating bracket 33 can further adjust the angle of the tabletop assembly 2 in the vertical plane to meet different usage requirements. When the tabletop assembly 2 is unfolded, the strengthening support frame 34, the first rotating arm 32 and the rotating bracket 33 together form a stable triangular structure to ensure the stability and load-bearing capacity of the tabletop assembly during use. When the tabletop assembly 2 needs to be stored, the coil spring assembly uses the elastic force of the spring to help the tabletop assembly automatically reset, reducing the required thrust and ensuring that the tabletop assembly smoothly moves into the installation frame 1.

[0090] Further explanation, the coil spring assembly 36 includes a coil spring body 361, a wire rope 362, a wire winding wheel 363 and a fixing piece 364. The coil spring body 361 is arranged on one side inside the installation frame 1, the wire winding wheel 363 is arranged on the other side inside the installation frame 1, the fixing piece 364 is arranged at the lower part of the base 31, one end of the wire rope 362 is wound around the coil spring body 361, and the other end is connected to the fixing piece 364 after passing around the wire winding wheel 363.

[0091] Among them, in the initial state, the coil spring body 361 is in a pre-tightened state and stores a certain amount of elastic potential energy. One end of the wire rope 362 is fixed on the coil spring body 361, and the other end is fixed on the fixing piece 364 of the base 31 after passing through the wire winding wheel 363. When the tabletop assembly 2 is unfolded from the installation frame 1, the base 31 moves outward along the guide rail frame 11. At this time, the wire rope 362 is gradually pulled out, and the elastic potential energy of the coil spring body 361 is gradually released, but still remains in a certain pre-tightened state. When it is necessary to store the tabletop assembly 2 back into the installation frame 1, the user only needs to apply a certain amount of thrust. Due to the pre-tightening force of the coil spring body 361, the wire rope 362 will automatically retract, driving the base 31 and the tabletop assembly 2 thereon to move inward. The wire winding wheel 363 plays a role of guiding and tensioning in this process to ensure that the wire rope 362 smoothly retracts and avoid knotting or jamming.

[0092] Combined with Figure 5 and Figure 7As shown, a limiting component 37 is provided on one side of the first driving member 35. The limiting component 37 includes: a limiting plate 371, a first limiting column 372, and a first tick pin 373. The first limiting column 372 is provided on one side of the limiting plate 371; the first tick pin 373 is provided on one side of the first limiting column 372; a plurality of first pin slots 321 are formed on the first rotating arm 32, and the first tick pin 373 is embedded in the first pin slot 321. A first installation slot 322 is formed on one side of the first rotating arm 32, a second installation slot 331 is formed on one side of the rotating bracket 33, one end of the reinforcing support frame 34 is rotatably embedded in the first installation slot 322, and the other end is rotatably embedded in the second installation slot 331; a second tick pin 341 is provided on the side where the reinforcing support frame 34 is rotatably embedded in the second installation slot 331, a second pin slot 332 is formed on one side of the second installation slot 331, and the second tick pin 341 is embedded in the second pin slot 332.

[0093] Among them, when the first rotating arm 32 rotates to a specific position, the first tick pin 373 will be embedded in the corresponding first pin slot 321 on the first rotating arm 32, thereby locking the position of the first rotating arm 32. During the embedding process, the first tick pin 373 will make a "click" sound, which allows the user to confirm that the first rotating arm 32 has been correctly locked in the predetermined position. When it is necessary to adjust the position of the first rotating arm 32, the first tick pin 373 can be manually disengaged from the first pin slot 321, thereby unlocking the first rotating arm 32 and enabling it to rotate freely. A "click" sound will also be made during the disengagement process to confirm successful unlocking. When the reinforcing support frame 34 is adjusted to a specific angle, the second tick pin 341 will be embedded in the corresponding second pin slot 332 on the second installation slot 331, thereby locking the position of the reinforcing support frame 34. During the embedding process, the second tick pin 341 will make a "click" sound, which allows the user to confirm that the reinforcing support frame 34 has been correctly locked in the predetermined position. When it is necessary to adjust the angle of the reinforcing support frame 34, the second tick pin 341 can be manually disengaged from the second pin slot 332, thereby unlocking the reinforcing support frame 34 and enabling it to rotate freely. A "click" sound will also be made during the disengagement process to confirm successful unlocking. The feedback of the "click" sound allows the user to obtain a clear confirmation during the operation process, enhancing the user experience.

[0095] Among them, the second rotating arm 23 is installed at the lower part of the mounting plate 22 and can rotate around an axis, providing an additional degree of rotational freedom. The user can adjust the angle of the second rotating arm 23 to achieve the rotation of the tabletop assembly in the horizontal direction. The hovering hinge 24 connects the tabletop bracket 21 and the tabletop body 25, allowing the tabletop body to freely hover within a certain range, increasing the flexibility of use. The user can adjust the angle of the tabletop body according to needs to meet different usage requirements. When the mounting plate 22 rotates to a specific position, the third click pin 334 will be embedded in the corresponding third pin slot 222 on the mounting plate 22, thereby locking the position of the mounting plate 22. A "click" sound will be emitted during the embedding process to confirm the successful locking. Limiting strips 221 and the second limiting post 333: The limiting strips 221 are arranged on both sides of the mounting plate 22 to limit the movement range of the mounting plate 22 on the rotating bracket 33 and prevent structural damage caused by excessive rotation. The second limiting post 333 guides and fixes the third click pin 334 to ensure that it is embedded in the third pin slot 222 at the correct position.

The second limiting block 335 is triangular in structure and is in contact with the first limiting block 58.

[0097] Specifically, the proximity switch 59 is electrically connected to the first driving member 35 and is used to transmit the start signal of the first driving member 35. When unlocking is required, the user pushes the push block 51 inward. The movement of the push block 51 will compress the first spring 54 and at the same time push the push rod 53 inward. The movement of the push rod 53 will push the second slider 57 to slide along the chute 561. The sliding of the second slider 57 will cause the slide bar 571 to slide along the second guiding groove 562 and the first guiding groove 551, thereby changing the position of the second slider 57. As the position of the second slider 57 changes, the position of the first limiting block 58 will also change accordingly, so that it no longer contacts the second limiting block 335 of the rotating bracket 33, thereby releasing the restriction on the rotating bracket 33. At the same time, the movement of the second slider 57 will trigger the proximity switch 59. After the proximity switch 59 detects the position change of the second slider 57, it will send a signal to the first driving member 35 to start the first driving member 35 for subsequent operations. Once the unlocking is completed, the user can release the push block 51. The first spring 54 will push the push block 51 back to the initial position. At the same time, the second spring 563 will push the first slider 56 back to the initial position, driving the second slider 57 and the first limiting block 58 to reset.

[0098] When it is necessary to store the tabletop body 25 and the tabletop bracket 21 into the installation frame 1, only after folding the tabletop body 25 and rotating its rotating bracket 33, the reinforcing support frame 34 and the second rotating arm 23 to the initial state, manually push the tabletop bracket 21, and under the action of the guide rail frame 11, the tabletop body 25 and the tabletop bracket 21 can smoothly enter the installation frame 1. Since during the movement of the rotating bracket 33, the rotating bracket 33 will drive the second limiting block 335 to move together, and both the first limiting block 58 and the second limiting block 335 are triangular structures, and their inclined surfaces will guide the second limiting block 335 to gradually slide, so that the second limiting block 335 gradually gets out of the restriction of the first limiting block 58. As the second limiting block 335 moves, the second slider 57 will slide in the chute 561, and the slide bar 571 will slide along the second guiding groove 562 and the first guiding groove 551, thereby changing the position of the second slider 57. The movement of the second slider 57 will trigger the proximity switch 59. After the proximity switch 59 detects the position change of the second slider 57, it will send a signal to the first driving member 35 to start the first driving member 35 for subsequent operations. Once the unlocking is completed, the user can release the push block 51. The first spring 54 will push the push block 51 back to the initial position. At the same time, the second spring 563 will push the first slider 56 back to the initial position, driving the second slider 57 and the first limiting block 58 to reset. After the first limiting block 58 resets, it will contact the second limiting block 335 again to ensure correct locking during the next use.

[0099] Combined with Figure 2 、 Figure 3 、 Figure 11 andFigure 15 As shown in the figure, the card board assembly 4 includes: a first snap board 42, a second snap board 43, a third snap board 44, a flip cover assembly 45, a second driving member 46, and a touch button 47. The first snap board 42 is snapped on one side of the mounting frame 1, and buffer pins 421 are provided on both sides of the first snap board 42; the second snap board 43 is snapped on the other side of the mounting frame 1, and a mounting cavity 41 is formed on the second snap board 43; the third snap board 44 is snapped between the first snap board 42 and the second snap board 43; a flip cover assembly 45 is rotatably provided on the second snap board 43, a second driving member 46 is provided on one side of the second snap board 43, the second driving member 46 is in transmission connection with the flip cover assembly 45, a touch button 47 is provided on one side of the second snap board 43, and the touch button 47 is electrically connected to the second driving member 46.

[0100] Among them, the second driving member 46 is a micro gear motor. Third limit posts 431 are respectively provided on both sides of the second snap board 43. The flip cover assembly 45 is rotatably sleeved on the third limit posts 431. The flip cover assembly 45 includes a rotating rod 451, a cover plate body 452, and meshing teeth 453. The rotating rod 451 is rotatably sleeved on the third limit posts 431. The cover plate body 452 is arranged between the two rotating rods 451. The cover plate body 452 is located on one side of the second snap board 43. The meshing teeth 453 are provided on the rotating rod 451, and the meshing teeth 453 are meshed with the second driving member 46.

[0101] Working principle:

[0102] In the initial state, the cover plate body 452 of the flip cover assembly 45 is in a closed state, covering the mounting cavity 41. When the user presses the touch button 47, the touch button 47 sends an electrical signal to the second driving member 46. After receiving the electrical signal, the second driving member 46 is activated, and the micro gear motor inside it starts to rotate. The gear on the output shaft of the micro gear motor meshes with the meshing teeth 453 of the flip cover assembly 45. Through gear transmission, the rotating rod 451 rotates, and the rotation of the rotating rod 451 drives the cover plate body 452 to rotate around the third limit post 431, thereby opening or closing the mounting cavity 41. When it is necessary to close the cover plate body 452, press the touch button 47 again, and the second driving member 46 rotates in the reverse direction, so that the cover plate body 452 is reset and the mounting cavity 41 is closed.

[0103] In some embodiments, a limit box 432 is provided on one side of the second snap board 43. A limit strip 454 is provided on one of the rotating rods 451, and the limit strip 454 is embedded in the limit box 432.

[0104] Combined Figure 18 As shown in the figure, the working mode of the present utility model is as follows:

[0105] Unfolding process:

[0106] In the initial state, the cover body 452 of the flip cover assembly 45 is in the closed state, covering the unlocking assembly 5 at the installation cavity 41. When the user presses the touch button 47, the touch button 47 sends an electrical signal to the second driving member 46. After receiving the electrical signal, the second driving member 46 starts, and the micro gear motor inside it starts to rotate. The gear on the output shaft of the micro gear motor meshes with the meshing teeth 453 of the flip cover assembly 45. Through gear transmission, the rotating rod 451 rotates. The rotation of the rotating rod 451 drives the cover body 452 to rotate around the third limiting post 431, and the cover body 452 opens, exposing the installation cavity 41. Secondly, the user presses the push block 51 of the unlocking assembly 5. The push block 51 moves inward, compressing the first spring 54. The push block 51 pushes the push rod 53 to move inward. The push rod 53 pushes the second slider 57 to slide along the chute 561. The sliding of the second slider 57 causes the sliding rod 571 to slide along the second guiding groove 562 and the first guiding groove 551, changing the position of the second slider 57. The position of the first limiting block 58 changes, so that it no longer contacts the second limiting block 335 of the rotating bracket 33, releasing the restriction on the rotating bracket 33. The movement of the second slider 57 triggers the proximity switch 59. After detecting the position change, the proximity switch 59 sends a signal to the first driving member 35. The first driving member 35 starts, and the micro gear motor inside it rotates. The gear on the output shaft meshes with the rack 12, driving the base 31 and the table board assembly 2 thereon to slide out of the installation frame 1 along the guide rail frame 11. The pull wire 362 is gradually pulled out, and the elastic potential energy of the coil spring body 361 is gradually released. After the table board assembly 2 slides out of the installation frame 1, the user manually rotates the first rotating arm 32 and the second rotating arm 23 to adjust the horizontal angle of the table board assembly. The rotating bracket 33 and the hovering hinge 24 allow the user to adjust the angle of the table board body 25 in the vertical plane. The strengthening support frame 34, the first rotating arm 32 and the rotating bracket 33 jointly form a stable triangular structure, ensuring the stability and load-bearing capacity of the table board assembly during use.

[0107] Storage process: The user folds the tabletop body 25, rotates its rotating bracket 33, reinforcing support bracket 34, and second rotating arm 23 to the initial state, manually pushes the tabletop bracket 21, and under the action of the guide rail frame 11, the tabletop body 25 and the tabletop bracket 21 slide into the installation frame 1. The movement of the rotating bracket 33 drives the second limit block 335 to move together. The inclined surface of the second limit block 335 guides it to gradually break away from the restriction of the first limit block 58. The movement of the second slider 57 triggers the proximity switch 59. After the proximity switch 59 detects the position change, it sends a signal to the first driving member 35. The first driving member 35 starts, and the micro gear motor inside it rotates. The gear on the output shaft meshes with the rack 12, driving the base 31 and the tabletop assembly 2 thereon to move along the guide rail frame 11 to the inside of the installation frame 1. At the same time, due to the pre-tightening force of the torsion spring body 361, the wire 362 will automatically retract, driving the base 31 and the tabletop assembly 2 thereon to move inward. The wire winding wheel 363 plays a role of guiding and tensioning during this process, ensuring the smooth retraction of the wire 362 and avoiding knotting or jamming. Once the first limit block 58 is unlocked, the first spring 54 will push the push block 51 back to the initial position. At the same time, the second spring 563 will push the first slider 56 back to the initial position, driving the second slider 57 and the first limit block 58 to reset. After the first limit block 58 is reset, it contacts the second limit block 335 again to ensure correct locking during the next use. The user presses the touch button 47 again, and the second driving member 46 rotates in the reverse direction to reset the cover body 452 and close the installation cavity 41.
