Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular, to a bidirectional push-pull mechanism, a bidirectional push-pull table board, and a bidirectional push-pull storage device. Background Art

[0002] A small table board is usually provided on the center console of a vehicle. In order to facilitate the use by both left and right occupants, the same small table board can be pulled out from two opposite directions. There are at least the following disadvantages:

[0003] 1. The small table board needs to be pulled out manually, resulting in a poor experience.

[0004] 2. When the small table board retracts into the storage area, it is easy to come out from the other side, making the operation inconvenient.

[0005] Therefore, it is necessary to design a bidirectional push-pull mechanism, a bidirectional push-pull table board, and a bidirectional push-pull storage device with more convenient operation and better experience. Summary of the Invention

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a bidirectional push-pull mechanism, a bidirectional push-pull table board, and a bidirectional push-pull storage device with more convenient operation and better experience.

[0007] The technical solution of the present invention provides a bidirectional push-pull mechanism, including a push-pull member, a first trigger assembly, a second trigger assembly, a first release assembly, a second release assembly, a first ejection assembly, and a second ejection assembly. The push-pull member is connected to the first ejection assembly and the second ejection assembly. The first release assembly is connected to the second ejection assembly, and the second release assembly is connected to the first ejection assembly.

[0008] Before triggering, the first ejection assembly and the second ejection assembly hold the push-pull member in the retracted position.

[0009] After the first trigger assembly is triggered, the first trigger assembly is linked with the first release assembly. The first release assembly drives the second ejection assembly to separate from the push-pull member. The first trigger assembly simultaneously triggers the first ejection assembly, and the first ejection assembly drives the push-pull member to pop out in the first direction.

[0010] After the second trigger assembly is triggered, the second trigger assembly is linked with the second release assembly. The second release assembly drives the first ejection assembly to separate from the push-pull member. The second trigger assembly simultaneously triggers the second ejection assembly, and the second ejection assembly drives the push-pull member to pop out in the second direction.

[0011] Furthermore, both the first release component and the second release component include a first connecting rod, a second connecting rod, a locking switch, and a lifting platform. One end of the first connecting rod acts on the first trigger component or the second trigger component. The other end of the first connecting rod is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is connected to the lifting platform. The second connecting rod is also connected to the locking switch. The lifting platform is connected to the first ejection component or the second ejection component;

[0012] When the first trigger component or the second trigger component is triggered, it drives the first connecting rod to rotate. The first connecting rod drives the second connecting rod to rotate. After the second connecting rod rotates, it drives the lifting platform to descend. The lifting platform drives the second ejection component or the first ejection component to descend and then separates from the pushing and pulling member. The locking switch locks the second connecting rod in the position where it drives the lifting platform to descend;

[0013] When the pushing and pulling member resets, the pushing and pulling member pushes the first connecting rod. The first connecting rod drives the second connecting rod to rotate. The second connecting rod unlocks from the locking switch. The second connecting rod releases the action on the lifting platform. The lifting platform rises under the action of the compression spring. The lifting platform drives the second ejection component or the first ejection component to rise and then connects with the pushing and pulling member.

[0014] Furthermore, an inclined groove is formed on the lifting platform. The inclined groove includes a deep groove end and a shallow groove end. The other end of the second connecting rod is connected to the inclined groove. When the lifting platform descends, the other end of the second connecting rod slides into the deep groove end. When the lifting platform rises, the other end of the second connecting rod slides into the shallow groove end.

[0015] Furthermore, both the first trigger component and the second trigger component include a button, a slider, and a telescopic block. The button is fixedly connected to the slider. The slider is slidably connected to the telescopic block. A dial is arranged on the slider. The dial acts on the first release component or the second release component;

[0016] Before triggering, the telescopic block is separated from the first ejection component or the second ejection component;

[0017] After triggering, the dial drives the first release component or the second release component. The telescopic block extends towards the first ejection component or the second ejection component and triggers the first ejection component or the second ejection component.

[0018] Further, both the first ejection assembly and the second ejection assembly include a base card, a needle, and a tension spring. The base card is slidably connected to the first release assembly or the second release assembly. One end of the tension spring is connected to the base card, and the other end is connected to the first release assembly or the second release assembly. The needle is connected between the base card and the first release assembly or the second release assembly;

[0019] Before triggering, the base card is clamped with the push-pull member, and the needle is inserted into the limit groove of the base card to hold the base card in the initial position, so that the tension spring is in a stretched state;

[0020] When the first trigger assembly is triggered, the first trigger assembly drives the base card of the second ejection assembly to separate from the push-pull member through the first release assembly. At the same time, the first trigger assembly triggers the base card of the first ejection assembly, so that the needle disengages from the limit groove of the base card, and the base card pops out under the action of the tension spring. The base card drives the push-pull member to pop out together in the first direction;

[0021] When the second trigger assembly is triggered, the second trigger assembly drives the base card of the first ejection assembly to separate from the push-pull member through the second release assembly. At the same time, the second trigger assembly triggers the base card of the second ejection assembly, so that the needle disengages from the limit groove of the base card, and the base card pops out under the action of the tension spring. The base card drives the push-pull member to pop out together in the second direction.

[0022] Further, two first inclined surfaces are provided on the push-pull member, and a second inclined surface is provided on the base card;

[0023] Before triggering, the first inclined surface is in contact with the second inclined surface, and the base card holds the push-pull member in the retracted position;

[0024] After triggering, one group of the first inclined surfaces is separated from the second inclined surface, and the other group of the first inclined surfaces remains in contact with the second inclined surface.

[0025] The present invention also provides a bidirectional push-pull table board, which includes an armrest box, an armrest cover plate, and a table board. The table board is arranged below the armrest cover plate, and the armrest cover plate covers the armrest box. It further includes a slide rail and the bidirectional push-pull mechanism described in any one of the above. The slide rail is installed between the table board and the push-pull member, and the slide rail can extend and retract in the first direction and the second direction.

[0026] Further, the slide rail includes at least two sections, and magnets are provided at the ends of each section of the slide rail.

[0027] The present invention also provides a two-way push-pull storage device, which includes a storage box, a slide rail, and the two-way push-pull mechanism described in any one of the above. The slide rail is arranged between the storage box and the push-pull member, and the slide rail can extend and retract in a first direction and a second direction.

[0028] Further, the two-way push-pull mechanism is arranged above the storage box, and the two-way push-pull mechanism further includes an extension member, and the extension member connects the push-pull member and the slide rail.

[0029] After adopting the above technical solutions, the following beneficial effects are achieved:

[0030] In the present invention, before triggering, the push-pull member is limited by two ejection components at the same time to prevent the push-pull member from disengaging to both sides. When one of the trigger components is triggered, the trigger component drives one of the ejection components to separate from the push-pull member and release the restriction on the push-pull member through the release component, and at the same time, the trigger component drives the other ejection component to eject the push-pull member. By triggering the trigger component, the present invention can realize the ejection of the push-pull member in the corresponding direction. After the push-pull member returns to its position, the two ejection components limit the push-pull member at the same time to prevent the push-pull member from disengaging from the other side when it returns to its position.

[0048] Embodiment 1:

[0049] Refer to Figures 1-5 As shown, it is a schematic diagram of the bidirectional push-pull mechanism in the first embodiment of the present invention.

[0050] As Figures 1-2 shown, the bidirectional push-pull mechanism includes a push-pull member 1, a first trigger assembly 2, a second trigger assembly 3, a first release assembly 4, a second release assembly 5, a first ejection assembly 6, and a second ejection assembly 7. The push-pull member 1 is connected to the first ejection assembly 6 and the second ejection assembly 7. The first release assembly 4 is connected to the second ejection assembly 7. The second release assembly 5 is connected to the first ejection assembly 6;

[0051] Before triggering, the first ejection assembly 6 and the second ejection assembly 7 hold the push-pull member 1 in the retracted position;

[0052] After the first trigger assembly 2 is triggered, the first trigger assembly 2 is linked with the first release assembly 4. The first release assembly 4 drives the second ejection assembly 7 to separate from the push-pull member 1. At the same time, the first trigger assembly 2 triggers the first ejection assembly 6, and the first ejection assembly 6 drives the push-pull member 1 to eject in the first direction;

[0053] After the second trigger assembly 3 is triggered, the second trigger assembly 3 is linked with the second release assembly 5. The second release assembly 5 drives the first ejection assembly 6 to separate from the push-pull member 1. At the same time, the second trigger assembly 3 triggers the second ejection assembly 7, and the second ejection assembly 7 drives the push-pull member 1 to eject in the second direction.

[0054] Specifically, as Figure 1 shown, the bidirectional push-pull mechanism further includes a bottom shell 8. The push-pull member 1 covers the top of the bottom shell 8, and other components are all installed inside the bottom shell 8. Figure 1 As the state before triggering, the first ejection assembly 6 and the second ejection assembly 7 hold the push-pull member 1 in the retracted position, so that the front and rear sides of the push-pull member 1 are flush with the front and rear sides of the bottom shell 8.

[0055] In this embodiment, Figure 1 above is the "second direction", and below is the "first direction". The first trigger assembly 2 is arranged in the first direction, the second trigger assembly 3 is arranged in the second direction, the first ejection assembly 6 is arranged on the right side, the second ejection assembly 7 is arranged on the left side, the first release assembly 4 is arranged between the first trigger assembly 2 and the second ejection assembly 7, and the second release assembly 5 is arranged between the second trigger assembly 3 and the first ejection assembly 6.

[0056] When the first trigger assembly 2 is triggered, the first trigger assembly 2 drives the first release assembly 4, and the first release assembly 4 drives the second ejection assembly 7 to separate from the push-pull member 1, releasing the limiting effect on the push-pull member 1 in the first direction. At the same time, the first trigger assembly 2 triggers the first ejection assembly 6, and the first ejection assembly 6 drives the push-pull member 1 to eject in the first direction.

[0057] When the second trigger assembly 3 is triggered, the second trigger assembly 3 drives the second release assembly 5, and the second release assembly 5 drives the first ejection assembly 6 to separate from the push-pull member 1, releasing the limiting effect on the push-pull member 1 in the second direction. At the same time, the second trigger assembly 3 triggers the second ejection assembly 7, and the second ejection assembly 7 drives the push-pull member 1 to eject in the second direction.

[0058] In this embodiment, the push-pull member 1 is of a plate-like structure, and limiting structures are provided on the left and right sides of the push-pull member 1. The first ejection assembly 6 and the second ejection assembly 7 act on the limiting structures to limit the push-pull member 1.

[0059] Furthermore, as Figure 3 shown, both the first release component 4 and the second release component 5 include a first connecting rod 41, a second connecting rod 42, a locking switch 43, and a lifting platform 44. One end of the first connecting rod 41 acts on the first trigger component 2 or the second trigger component 3, the other end of the first connecting rod 41 is rotatably connected to one end of the second connecting rod 42, the other end of the second connecting rod 42 is connected to the lifting platform 44, the second connecting rod 42 is also connected to the locking switch 43, and the lifting platform 44 is connected to the first ejection component 6 or the second ejection component 7;

[0060] When the first trigger component 2 or the second trigger component 3 is triggered, it drives the first connecting rod 41 to rotate. The first connecting rod 41 drives the second connecting rod 42 to rotate. After the second connecting rod 42 rotates, it drives the lifting platform 44 to descend. The lifting platform 44 drives the second ejection component 7 or the first ejection component 6 to descend and then separate from the push-pull member 1. The locking switch 43 locks the second connecting rod 42 at the position where it drives the lifting platform 44 to descend;

[0061] When the push-pull member 1 resets, the push-pull member 1 pushes the first connecting rod 41. The first connecting rod 41 drives the second connecting rod 42 to rotate. The second connecting rod 42 unlocks from the locking switch 43. The second connecting rod 42 releases the action on the lifting platform 44. The lifting platform 33 rises under the action of the compression spring. The lifting platform 44 drives the second ejection component 7 or the first ejection component 6 to rise and then connect with the push-pull member 1.

[0062] Specifically, as Figure 2 shown, before triggering, the second trigger component 3 does not contact the second release component 5. Optionally, before triggering, the trigger component and the corresponding release component may also be in contact.

[0063] As Figures 3-4 described, taking the triggering of the second release component 5 as an example, press the second trigger component 3 in the first direction. After the second trigger component 3 contacts the first connecting rod 41, it drives the first connecting rod 41 to rotate. The first connecting rod 41 drives the second connecting rod 42 to rotate. The second connecting rod 42 rotates to press the locking switch 43, causing the locking switch 43 to lock. After that, the second connecting rod 42 no longer rotates. While the second connecting rod 42 rotates, it drives the lifting platform 44 to descend. The lifting platform 44 drives the first ejection component 6 thereon to descend together, so that the first ejection component 6 separates from the push-pull member 1 and releases the limit on the push-pull member 1.

[0064] As Figure 5 shown, the second trigger component 3 simultaneously triggers the second ejection component 7, causing the push-pull member 1 to eject in the second direction.

[0065] When the push-pull member 1 is reset, the push-pull member 1 is pushed back along the second direction. A reset member (not shown in the figure) is provided on the back surface of the push-pull member 1. The reset member acts on the first link 41, and the first link 41 drives the second link 42 to rotate. The second link 42 presses the locking switch 43 again, driving the locking switch 43 to unlock. At the same time, the second link 42 releases the downward force on the lifting platform 44. A compression spring 45 is provided at the top of the lifting platform 44. The second link 42 overcomes the pressure of the compression spring 45 to lift the lifting platform 44. The lifting platform 44 drives the first ejection assembly 6 to rise, and the first ejection assembly 6 limits the position of the push-pull member 1 again, holding the push-pull member 1 in the retracted position.

[0066] The structure and working process of the first release assembly 4 are similar to those of the second release assembly 5, and will not be described in detail.

[0067] Further, as Figure 4 shown, an inclined groove 441 is formed on the lifting platform 44. The inclined groove 441 includes a deep groove end and a shallow groove end. The other end of the second link 42 is connected to the inclined groove 441. When the lifting platform 44 descends, the other end of the second link 42 slides into the deep groove end. When the lifting platform 44 rises, the other end of the second link 42 slides into the shallow groove end.

[0068] Specifically, a convex column 421 is provided at the end of the second link 42, and the convex column 421 is inserted into the inclined groove 441. The inclined groove 441 includes a deep groove end and a shallow groove end. Before triggering, the convex column 421 is inserted into the wire groove end, and the lifting platform 44 is in the upper position under the action of the compression spring; after triggering, the convex column 421 slides into the deep groove end, driving the lifting platform 44 to descend, and the lifting platform 44 compresses the compression spring. When the push-pull member 1 is reset, the convex column 421 slides into the shallow groove end again, and the lifting platform 44 rises under the action of the compression spring.

[0069] Further, as Figures 2-3 shown, both the first trigger assembly 2 and the second trigger assembly 3 include a button 21, a slider 22, and a telescopic block 23. The button 21 is fixedly connected to the slider 22, the slider 22 is slidably connected to the telescopic block 23, and a dial member 221 is provided on the slider 22. The dial member 221 acts on the first release assembly 4 or the second release assembly 5;

[0070] Before triggering, the telescopic block 23 is separated from the first ejection assembly 6 or the second ejection assembly 7;

[0071] After triggering, the dial member 221 drives the first release assembly 4 or the second release assembly 5, and the telescopic block 23 extends toward the first ejection assembly 6 or the second ejection assembly 7 and triggers the first ejection assembly 6 or the second ejection assembly 7.

[0072] Specifically, taking the second trigger assembly 3 as an example:

[0073] As Figure 2As shown, the button 21 is arranged on the upper side edge of the bottom case 8, that is, in the second direction. When it is necessary to eject the push-pull member 1 from the second direction, the button 21 of the second trigger assembly 3 is pressed. The slider 22 is fixedly connected to the button 21. A telescopic spring (not shown in the figure) is arranged on the slider 22. When the button 21 is pressed, the button 21 drives the slider 22 to move together towards the first direction. After the button 21 is released, under the action of the telescopic spring, the slider 22 and the button 21 are reset.

[0074] As Figure 3 shown, an inclined groove 222 is arranged on the slider 22. One end of the telescopic block 23 is slidably connected to the inclined groove 222, and the other end of the telescopic block 23 acts on the ejection assembly.

[0075] After the button 21 is pressed, the button 21 drives the slider 22 to move together towards the first direction. The slider 22 pushes the telescopic block 23 to move towards the second ejection assembly 7, so as to trigger the second ejection assembly 7 to eject the push-pull member 1 towards the second direction.

[0076] After the button 21 is released, the slider 22 and the button 21 are reset. The slider 22 drives the telescopic block 23 to be reset as well and separates from the second ejection assembly 7.

[0077] When the push-pull member 1 is pushed to retract towards the first direction, the push-pull member 1 drives the second ejection assembly 7 to be reset.

[0078] The structure and working principle of the first trigger assembly 2 are similar and will not be elaborated here.

[0079] Further, as Figure 3 shown, both the first ejection assembly 6 and the second ejection assembly 7 include a base card 61, a needle 62 and a tension spring 63. The base card 61 is slidably connected to the first release assembly 4 or the second release assembly 5. One end of the tension spring 63 is connected to the base card 61, and the other end is connected to the first release assembly 4 or the second release assembly 5. The needle 62 is connected between the base card 61 and the first release assembly 4 or the second release assembly 5;

[0080] Before triggering, the base card 61 is clamped with the push-pull member 1. The needle 62 is inserted into the limit groove 611 of the base card 61 to keep the base card 61 in the initial position, so that the tension spring 63 is in a stretched state;

[0081] When the first trigger assembly 2 is triggered, the first trigger assembly 2 drives the base card 61 of the second ejection assembly 7 to separate from the push-pull member 1 through the first release assembly 4. At the same time, the first trigger assembly 2 triggers the base card 61 of the first ejection assembly 6, so that the needle 62 disengages from the limit groove 611 of the base card 61. The base card 61 pops out under the action of the tension spring 63, and the base card 61 drives the push-pull member 1 to pop out together towards the first direction;

[0082] When the second trigger component 3 is triggered, the second trigger component 3 drives the base card 61 of the first ejection component 6 to separate from the push-pull member 1 through the second release component 5. At the same time, the second trigger component 3 triggers the base card 61 of the second ejection component 7, so that the needle 62 is disengaged from the limit slot 611 of the base card 61. The base card 61 pops out under the action of the tension spring 63, and the base card 61 drives the push-pull member 1 to pop out together towards the second direction.

[0083] Specifically, as Figures 3-4 shown, when the second trigger component 3 is triggered, the lifting platform 44 of the second release component 5 drives the first ejection component 6 to descend, so that the base card 61 is separated from the push-pull member 1, and the restriction on the second direction of the push-pull member 1 is released. At the same time, the telescopic block 23 of the second trigger component 3 extends and then pushes the base card 61 of the second ejection component 7, so that the needle 62 is disengaged from the limit slot 611. The base card 61 moves towards the second direction under the action of the tension spring 63, and the base card 61 drives the push-pull member 1 to pop out together towards the second direction at the same time.

[0084] When the push-pull member 1 is pushed to retract, after the push-pull member 1 contacts the base card 61 of the second ejection component 7, it drives the base card 61 to return to its position, and the needle 62 is inserted into the limit slot 611 again, so that the tension spring 63 is stretched. The push-pull member 1 also drives the second release component 5 at the same time, so that the first ejection component 6 rises and is limited to the push-pull member 1.

[0085] In this embodiment, the limit slot 611 is a Y-shaped slot. When the ejection component is in the energy storage state, the needle 62 enters the limit slot 611. When the telescopic block 23 pushes the base card 61, the needle 62 is disengaged from the limit slot 611 and slides along the outer edge of the Y-shaped slot. When the base card 61 returns to its position, the needle 62 slides into the limit slot 611 again along the outer edge of the Y-shaped slot.

[0086] In this embodiment, two first inclined surfaces 11 are provided on the push-pull member 1, and a second inclined surface 612 is provided on the base card 61;

[0087] Before triggering, the first inclined surface 11 is in contact with the second inclined surface 612, and the base card 61 keeps the push-pull member 1 in the retracted position;

[0088] After triggering, one group of the first inclined surfaces 11 is separated from the second inclined surface 612, and the other group of the first inclined surfaces 11 remains in contact with the second inclined surface 612.

[0089] Specifically, as Figure 1As shown in the figure, before triggering, each of the left and right sides of the push-pull member 1 is provided with a first inclined surface 11, and the two base cards 61 are provided with second inclined surfaces 612. Among them, the second inclined surface 612 of the first ejection assembly 6 is in contact with the right first inclined surface 11 to limit the movement of the push-pull member 1 in the second direction; the second inclined surface 612 of the second ejection assembly 7 is in contact with the left first inclined surface 11 to limit the movement of the push-pull member 1 in the first direction.

[0090] As Figure 5 shown, when the push-pull member 1 ejects in the second direction, the second inclined surface 612 of the second ejection assembly 7 pushes the first inclined surface 11 of the push-pull member 1. At this time, the first ejection assembly 6 descends, and the first inclined surface 11 and the second inclined surface 612 do not act on each other.

[0091] When the push-pull member 1 is pushed to reset and retract, the first inclined surface 11 on the left side of the push-pull member 1 pushes the second inclined surface 612 of the second ejection assembly 7 to move in the first direction, driving the reset of the second ejection assembly 7; at the same time, the reset block of the push-pull member 1 also drives the second release assembly 5, and the second release assembly 5 drives the first ejection assembly 6 to rise, so that the second inclined surface 612 of the first ejection assembly 6 just engages with the first inclined surface 11 on the right side of the push-pull member 1 after returning, and the push-pull member 1 is limited again.

[0092] In this embodiment, the end of the telescopic block 23 is also set as an inclined surface. When the telescopic block 23 extends, it contacts the second inclined surface 612 of the base card 61 to push the base card 61.

[0093] Optionally, other shaped limiting structures can also be provided between the push-pull member 1 and the ejection assembly, such as: the cooperation of a protrusion and a groove, or the cooperation between a serrated surface and a serrated surface, etc.

[0094] In this embodiment, as Figure 6 shown, it further includes a limit pin 64. The limit pin 64 is fixedly connected to the base card 61, and a card slot 12 is also provided on the side of the push-pull member 1. Before the push-pull member 1 is ejected, the limit pin 64 is snapped into the card slot 12, and the limit pin 64 is used to limit the ejection of the push-pull member 1.

[0095] As Figure 7 shown, when the base card 61 ejects forward, the base card 61 drives the limit pin 64 to move forward together. The limit pin 64 slides into the chute 442 of the lifting table 44 and disengages from the card slot 12, releasing the restriction on the push-pull member 1, and the base card 61 can push the push-pull member 1 to eject outward.

[0096] In this embodiment, before triggering, the push-pull member 1 is limited by two ejection components at the same time to prevent the push-pull member 1 from slipping out to both sides. When one of the trigger components is triggered, the trigger component drives one of the ejection components to separate from the push-pull member through the release component and releases the restriction on the push-pull member. At the same time, the trigger component drives the other ejection component to eject the push-pull member. By triggering one of the trigger components in this embodiment, the push-pull member 1 can be ejected in the corresponding direction. After the push-pull member 1 returns to its position, the two ejection components limit the push-pull member 1 at the same time to prevent the push-pull member 1 from slipping out from the other side when it returns to its position. In this embodiment, it is not necessary for the user to manually pull out the push-pull member. By pressing the trigger component on one side, the effect of ejecting the push-pull member towards the corresponding side is achieved, which is convenient to operate; and after the push-pull member is pushed back, it will not slip out from the other side, bringing a better user experience.

[0097] Embodiment Two:

[0098] See Figures 8-10 As shown, it is a schematic diagram of the two-way push-pull table board in the second embodiment of the present invention.

[0099] The two-way push-pull table board includes an armrest box 10, an armrest cover plate 20 and a table board 30. The table board 30 is arranged below the armrest cover plate 20, and the armrest cover plate 20 covers the armrest box 10. It further includes a slide rail 40 and the two-way push-pull mechanism in Embodiment One and its variants. The slide rail 40 is installed between the table board 30 and the push-pull member 1, and the slide rail 40 can extend and retract in the first direction and the second direction.

[0100] Specifically, the two-way push-pull mechanism can be arranged in the armrest box 10 and is connected to the table board 30 through the slide rail 40.

[0101] The buttons 21 of the two-way push-pull mechanism are exposed from both sides of the armrest box 10. There are also notches opened on the armrest box 10 to facilitate the extension of the table board 30, the slide rail 40 and the push-pull member 1.

[0102] As Figure 10 shown, when pressing the button 21 on one side, the push-pull member 1 pops out from this side. The push-pull member 1 drives the table board 30 to extend together, which is convenient for the user to pull the table board 30 and drives the extension of the slide rail 40.

[0103] When the user has finished using it, push the table board 30 back until the slide rail 40 is completely retracted. Continue to push the table board 30 to drive the push-pull member 1 to retract. After the push-pull member 1 returns to its position, it locks with the first ejection component 6 and the second ejection component 7.

[0104] When the user on the other side also needs to use the table board 30, press the other button 21 from the other side so that the table board 30 extends from the other side.

[0105] In this embodiment, the table board 30 includes multiple folding boards. After the table board 30 is fully extended, the folding boards are opened to expand the usable area of the table board 30. After use, the table board 30 is folded to the minimum volume and then pushed back.

[0106] Further, as Figure 10 shown, the slide rail 40 includes at least two sections, and magnets 401 are provided at the ends of each section of the slide rail 40.

[0107] The magnets 401 cause an obvious change in the force value when each section of the slide rail 40 reaches the fixed stroke, with a holding force when opening and an adsorption force when retracting. To enable the slide rails 40 at all levels to be opened and retracted step by step, the magnetic forces of the magnets 401 on each section of the slide rail 40 can be set to different values.

[0108] Preferably, a lifting mechanism can also be added to the slide rail 40. According to the self-locking principle of the connecting rod, the table board 30 is kept elevated to be in the same plane as the armrest cover 20 when opened, and lowered for easy retraction when stored.

[0109] The two-way push-pull table board in this embodiment can be used for the armrest box in the middle of the front row seats of a car, and can also be used for the armrest box in the back row, or applied to other armrest boxes.

[0110] Embodiment Three:

[0111] See Figures 11-13 shown, which is a schematic diagram of the two-way push-pull storage device in Embodiment Three of the present invention.

[0112] The two-way push-pull storage device includes a storage box 50, a slide rail 40, and the two-way push-pull mechanism in Embodiment One and its variants. The slide rail 40 is arranged between the storage box 50 and the push-pull member 1, and the slide rail 40 can extend and retract in the first direction and the second direction.

[0113] Specifically, the two-way push-pull storage device further includes a top shell 60. The top shell 60 is arranged above the two-way push-pull mechanism and covers the left and right sides of the storage box 50. Before triggering, the storage box 50 is received inside the top shell 60.

[0114] When a button 21 is triggered, the push-pull member 1 takes out the slide rail 40 and the storage box 50, and the user manually pulls the storage box 50 along the slide rail 40 to facilitate taking or putting in items.

[0115] After use, the user pushes the storage box 50 back. The storage box 50 drives the slide rail 40 to retract. Until the slide rail 40 is completely retracted, continue to push the storage box 50. The storage box 50 drives the push-pull member 1 to retract. After the push-pull member 1 retracts, it is locked by the first ejection assembly 6 and the second ejection assembly 7.

[0116] Further, as Figures 12-13As shown, the bidirectional push-pull mechanism is arranged above the storage box 50. The bidirectional push-pull mechanism further includes an extension member 9, and the extension member 9 connects the push-pull member 1 and the slide rail 40.

[0117] Specifically, as Figure 13 shown, the push-pull member 1 is located above the storage box 50. The extension member 9 bends from above and then extends in the vertical direction to connect with the slide rail 40, and the slide rail 40 is installed on the left and right sides of the storage box 50.

[0118] After the push-pull member 1 is ejected, it drives the extension member 9 and the slide rail 40 to be ejected together, and then the slide rail 40 drives the storage box 50 to be ejected together.

[0119] By implementing this embodiment, the bidirectional ejection of the storage box 50 can be realized, meeting the function of conveniently accessing items from both sides.

[0120] The present invention is not limited to being used in vehicles and can also be used in other devices that need to achieve the bidirectional push-pull function.

[0121] The above are only the principles and preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, based on the principle of the present invention, several other variants can also be made, which should also be regarded as the protection scope of the present invention.
