Description

Technical Field

[0001] This invention relates to the field of automotive table technology, and more particularly to a fully automatic automotive height-adjustable table. Background Technology

[0002] With the development of the automotive industry, cars are no longer just a means of transportation, but also a mobile carrier for business offices and leisure and entertainment. As an important supporting component for the rear space, the ease of use and degree of automation of car lift tables have become the core needs of users.

[0003] In the prior art, for example, invention patent application number 202211420378.8 discloses a sliding concealed lifting table. This lifting table achieves horizontal translation of the table body by driving a gear rack and pinion via a drive motor, and raises and lowers the tabletop via an electric push rod. The table body includes a rectangular panel and two curved panels forming a folding tabletop. However, after the folding tabletop rises to a predetermined height, the curved panels need to be manually unfolded and rotated 90° to fix the tabletop to the tabletop base. This manual operation is cumbersome and reduces the user experience. Furthermore, manual operation of the tabletop poses a safety hazard while the vehicle is in motion, failing to meet the automated and intelligent usage requirements of high-end automotive tables. Therefore, we propose a fully automatic automotive lifting table to solve the above problems. Summary of the Invention

[0004] This invention addresses the shortcomings of existing automotive sliding and concealing lifting tables, which require manual unfolding of the folding tabletop, are cumbersome to operate, and pose safety hazards. It provides a fully automatic automotive lifting table.

[0005] This invention is achieved through the following technical solution:

[0006] A fully automatic car lift table includes a base and a support seat that is slidably mounted on the base. The support seat has a drive chamber connected to its interior through a telescopic shell, and a second servo motor is installed inside the support seat. The output end of the second servo motor is fixedly connected to the drive chamber through a telescopic screw.

[0007] The top of the drive compartment is equipped with a folding table, and the drive compartment is equipped with a drive mechanism that automatically unfolds the folding table. The folding part of the folding table is equipped with an anti-pinch mechanism.

[0008] In a preferred embodiment of the present invention, the driving mechanism includes a mounting compartment fixed to the bottom surface of the folding table and a third servo motor fixed to the mounting compartment. The mounting compartment has two parallel second racks inside, both of which are slidably connected to the mounting compartment. The ends of the two second racks that are far apart from each other extend to the outside of the driving compartment. A second gear is provided between the two second racks. The second gear is driven by the third servo motor. The third servo motor drives the outer ends of the two second racks to extend out of the driving compartment, thereby pushing the folding table to unfold.

[0009] In a preferred embodiment of the present invention, a limiting strip is provided on the surface of the second rack along its length direction, and a limiting groove adapted to the limiting strip is provided on the inner wall of the mounting chamber. The stability of the second gear in the mounting chamber is improved by the cooperation between the limiting strip and the limiting groove.

[0010] In a preferred embodiment of the present invention, a pushing block is provided on the upper surface of the outer end of each of the two second racks. The pushing block is in contact with the bottom surface of the folding table, and the outer end of the pushing block is provided with a rounded corner. The pushing block increases the contact area with the curved table, making it easier to push and unfold it.

[0011] In a preferred embodiment of the present invention, the drive mechanism is connected to the operation panel disposed on the support base via a connecting line, and the connecting line is spirally arranged. The spiral connecting line can be spirally retracted in an orderly manner during the folding table's descent and retraction, reducing the factors of tangling and knotting of the connecting line.

[0012] In a preferred embodiment of the present invention, the folding table includes a rectangular table and an arc-shaped table hinged to both sides of the rectangular table, and the width of the rectangular table is not less than the width of the drive compartment, which facilitates the folding of the arc-shaped table.

[0013] In a preferred embodiment of the present invention, the anti-pinch mechanism includes filler strips disposed on both sides of the rectangular tabletop. The filler strips are triangular in shape and are installed on the side wall of the rectangular tabletop in the upper and lower directions. During the upward rotation of the curved tabletop, the filler strips are pushed upward, thereby reducing the risk of items or hands being pinched at the hinge during the automatic unfolding of the curved tabletop.

[0014] In a preferred embodiment of the present invention, a first tilt angle α is provided on the side wall of the rectangular tabletop, and a second tilt angle b is provided on the side wall of the curved tabletop. The sum of the angles of the first tilt angle α and the second tilt angle b is the same as the bottom angle of the filler strip, so that when the filler strip moves to the uppermost end, the upper surfaces of the rectangular tabletop and the curved tabletop are flush. At the same time, the first tilt angle α facilitates pushing the filler strip upward.

[0015] In a preferred embodiment of the present invention, a compression strip is provided at the lower end of the side of the filling strip near the curved tabletop, and a limiting groove adapted to the compression strip is provided on the side wall of the curved tabletop. When the compression strip is located in the limiting groove, the upper surfaces of the curved tabletop and the rectangular tabletop are flush. The compression strip facilitates the compression of the filling strip by the curved tabletop, thereby facilitating its upward movement. At the same time, the compression strip can prevent the filling strip from closing with the curved tabletop during the unfolding of the folded tabletop, thereby further reducing the risk of items or hands being pinched.

[0016] In a preferred embodiment of the present invention, a silicone layer is provided on the upper end of the side wall of the filler strip. The thickness of the silicone layer is 0.5mm-1mm. The silicone layer can improve the sealing between the filler strip and the rectangular table or the curved table after folding.

[0017] In a preferred embodiment of the present invention

[0018] The beneficial effects of this invention are:

[0019] 1. In this invention, after the folding table is raised by the second servo motor, the second gear is rotated by the third servo motor, which drives the second racks on both sides to move outward synchronously. The second racks on both sides simultaneously push the arc-shaped table on both sides to rotate outward, thereby realizing the automatic unfolding of the arc-shaped table. This replaces the manual operation steps of the prior art, improves the convenience of use, and meets the intelligent use needs of vehicle table.

[0020] 2. As the curved tabletop automatically unfolds, the present invention pushes the filling strip at the hinge point to move upward, which structurally reduces the risk of items or hands being pinched at the hinge point during the automatic unfolding of the curved tabletop, and greatly improves the safety of the automatic unfolding process.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention. The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for illustrating and understanding the present invention, and not for limiting the present invention.

[0034] like Figure 1-11The fully automatic car lift table shown includes a base 1 and a support 3 slidably mounted on the base 1. The outer end of the support 3 is provided with an operation panel. The base 1 has a "U" shaped structure. A first rack 11 arranged along the length direction is fixed inside the base 1. A slide 2 is provided at the bottom of the support 3. A slide rail is provided at the bottom of the slide 2. The slide 2 is slidably connected to the base 1 through the slide rail. A first servo motor 4 is installed inside the support 3. The output end of the first servo motor 4 extends into the interior of the base 1. A first gear 41 is fixed at the output end of the first servo motor 4. The first gear 41 meshes with the first rack 11. The operation of the first servo motor 4 drives the first gear 41 to rotate. The cooperation between the first gear 41 and the first rack 11 drives the support 3 to move horizontally on the base 1 to realize the translation of the table.

[0035] The support base 3 has arc-shaped grooves 31 on both sides and a storage cavity 32 at the upper end. A second servo motor 5 is fixed in the storage cavity 32 by bolts. The output end of the second servo motor 5 is vertically upward and connected to a telescopic screw 51. A telescopic housing 52 is sleeved on the outside of the telescopic screw 51. The bottom end of the telescopic housing 52 is fixed to the bottom of the storage cavity 32. The top end of the telescopic screw 51 and the top end of the telescopic housing 52 are both fixed to the bottom of the drive chamber 6. The telescopic screw 51 consists of four screw sections. The two adjacent screw sections are connected by threads. The height can be adjusted by the four telescopic screw sections 51. At the same time, the cross-section of the telescopic housing 52 is not circular. The telescopic housing 52 protects the telescopic screw 51 and prevents the telescopic housing 52 from rotating with the telescopic screw 51. Then, the rotation of the second servo motor 5 drives the telescopic screw 51 to extend or retract in sequence, so as to realize the raising or lowering of the folding table 7.

[0036] The size of the storage cavity 32 is adapted to the drive compartment 6. When the folding table 7 is lowered to the bottom, the drive compartment 6 is located in the storage cavity 32, and the storage cavity 32 stores the drive compartment 6.

[0037] The drive compartment 6 has a hollow structure with a folding table 7 installed on its top and a drive mechanism 8 fixed inside. The folding table 7 has rounded corners around its perimeter and consists of a rectangular table 71 and two arc-shaped table 72 symmetrically arranged on both sides of the rectangular table 71. The rectangular table 71 and the arc-shaped table 72 are hinged together. The arc-shaped table 72 is adapted to the arc-shaped grooves 31 on both sides of the support base 3. After the folding table 7 is lowered, the arc-shaped table 72 is located in the arc-shaped grooves 31 and fits tightly against the support base 3.

[0038] The drive mechanism 8 includes a mounting chamber 81 bolted to the drive chamber 6. A third servo motor 82 is fixed to the bottom of the mounting chamber 81, and a reducer is provided at the output end of the third servo motor 82. Two parallel second racks 83 are slidably mounted inside the mounting chamber 81. Limiting strips 832 are integrally formed on the upper and lower surfaces of the second racks 83, and a limiting groove 85 along the length of the second racks 83 is provided on the inner wall of the mounting chamber 81. The limiting strips 832 are slidably mounted in the limiting grooves 85, thereby ensuring the straightness of the movement of the second racks 83. A second tooth is installed between the two parallel second racks 83. The wheel 84 and the second gear 84 mesh with the second racks 83 on both sides. The second gear 84 is driven by the third servo motor 82. The third servo motor 82 drives the second gear 84 to rotate, which in turn drives the outer ends of the two second racks 83 to move away from each other, so that their outer ends are exposed in the drive chamber 6. In order to facilitate the pushing and unfolding of the curved table panels 72 on both sides, the upper surface of the outer end of the two second racks 83 is provided with a pushing block 831. The pushing block 831 is in contact with the bottom surface of the folding table panel 7, and the outer end of the pushing block 831 is provided with a rounded corner. The setting of the pushing block 831 increases the contact area with the curved table panel 72.

[0039] The drive mechanism 8 is connected to the operation panel set on the support base 3 via the connecting line 9. The connecting line 9 is spirally arranged. The spiral connecting line 9 can retract in an orderly spiral shape during the descent and retraction of the folding table 7, reducing the factors of the connecting line 9 getting tangled or knotted.

[0040] An anti-pinch mechanism is also provided at the folding point of the folding table 7. The anti-pinch mechanism includes filling strips 73 on both sides of the rectangular table 71. The filling strips 73 are arranged in an inverted triangle shape, and a slider is provided on one side of the filling strips 73. A sliding groove adapted to the slider is opened on the side wall of the rectangular table 71. The filling strips 73 are slidably installed on the side wall of the rectangular table 71 in the up and down directions. In order to make the curved table 72 fold smoothly, a first tilt angle a is opened on the side wall of the rectangular table 71, and a second tilt angle b is opened on the side wall of the curved table 72. The sum of the angles of the first tilt angle a and the second tilt angle b is the same as the bottom angle of the filling strip 73. When the filling strip 73 moves to the top, the upper surfaces of the rectangular table 71 and the curved table 72 are flush. At the same time, the first tilt angle a facilitates pushing the filling strip 73 upward.

[0041] Furthermore, to facilitate pushing the filling strip 73, a compression strip 731 is provided at the lower end of the side of the filling strip 73 near the curved table 72, and a limiting groove 721 adapted to the compression strip 731 is provided on the side wall of the curved table 72. When the compression strip 731 is located in the limiting groove 721, the upper surface of the curved table 72 is flush with the upper surface of the rectangular table 71. The compression strip 731 facilitates the compression of the filling strip 73 by the curved table 72, thereby facilitating its upward movement. At the same time, the compression strip 731 at the lower end of the filling strip 73 can prevent the filling strip 73 from closing with the curved table 72 during the unfolding of the folding table 7. The lower end setting allows for a larger angle between the curved table 72 and the filling strip 73 compared to the upper end setting, and prevents it from closing during the folding process, thereby further reducing the risk of items or hands being pinched at the hinge during the automatic unfolding of the curved table 72.

[0042] A silicone layer is also provided on the upper side wall of the filler strip 73. The thickness of the silicone layer is 0.5mm-1mm. The silicone layer can improve the sealing between the filler strip 73 and the rectangular table 71 and the curved table 72 after folding, and improve the performance.

[0043] In this embodiment, the first servo motor 4 is turned on, and the first servo motor 4 drives the first gear 41 to rotate along the first rack 11, thereby driving the slide 2 and the support 3 to move horizontally outward along the base 1. After moving to the preset position, the first servo motor 4 automatically stops.

[0044] After the support base 3 is moved into position, the second servo motor 5 is started, which drives the telescopic screw 51 to rotate in the forward direction. The four screw sections extend in sequence, pushing the telescopic housing 52 and the drive chamber 6 to move vertically upward, thereby driving the folding table 7 to rise. When the maximum stroke of the telescopic screw 51 is reached, the second servo motor 5 stops automatically. During this process, the spiral connecting line 9 stretches synchronously with the rise of the drive chamber 6.

[0045] After the folding table 7 is raised and lowered to the position, the third servo motor 82 is started, which drives the second gear 84 to rotate, thereby driving the two second racks 83 to move outward synchronously along the limiting slide groove 85. By pushing the block 831 to contact the bottom surface of the arc-shaped table 72 and applying a pushing force, the two arc-shaped table 72 are flipped outward around the hinge.

[0046] During the unfolding process of the curved tabletop 72, its sidewalls contact the extrusion strip 731, pushing the filling strip 73 to move upward along the slide groove, reducing the risk of pinching hands or jamming objects. When the curved tabletop 72 is fully unfolded, the extrusion strip 731 is inserted into the limiting groove 721, the filling strip 73 moves to the top, and the upper surface of the rectangular tabletop 71 is flush with the upper surface of the curved tabletop 72. The third servo motor 82 stops automatically. At this time, the folding tabletop 7 forms a complete circular desktop, which can be used for office work and leisure. It unfolds automatically without manual operation.

[0047] After use, the user presses the storage button on the control panel. The third servo motor 82 rotates in the opposite direction, causing the second rack 83 to retract inward. The curved table 72 folds inward under its own weight, and the filling strip 73 slides down to its initial position under gravity. Then, the second servo motor 5 rotates in the opposite direction, the telescopic screw 51 retracts, and the drive chamber 6 and the folding table 7 descend. The drive chamber 6 is embedded in the storage cavity 32, and the curved table 72 is embedded in the curved groove 31. They are spirally retracted through the connecting line 9 to reduce the risk of tangling. Finally, the first servo motor 4 rotates in the opposite direction, causing the support base 3 to move horizontally to the hidden position between the seats, completing the overall storage.
