Description

A folding table Technical Field

[0001] This invention specifically relates to a folding tabletop. Background Technology

[0002] Automobiles are widely used as a common means of transportation. When choosing a car, the interior decoration and functions are important factors that users consider first. As people's demands for additional car functions increase, aiming to improve the driving experience and enhance the car's human-centered design, armrests are usually installed between the driver and passenger seats, and central aisles are located between the main and secondary seats in commercial vehicles. One of the main functions of both armrests and central aisles is to store items. Especially in commercial vehicles positioned for business activities, they undertake a significant role in business meetings and negotiations. Since business meetings involve various documents and materials, or require presentations, a conference table is indispensable. Due to the limited space inside a car, in-vehicle folding tables are adopted to balance space arrangement and practicality.

[0003] Existing folding tables pose a risk of users accidentally putting their hands into the gaps after unfolding, resulting in pinched fingers. Furthermore, existing folding tables typically consist of two independent folding table components, creating gaps between them. When using one component alone, they are arranged in a crisscross pattern, increasing the risk of hand injury when placed between them. Moreover, existing folding tables are prone to shifting and accidentally collapsing during vehicle movement, further increasing the risk of injury to drivers and passengers. Therefore, this invention proposes a more reliable and safer folding table. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a folding table that is simple in structure, easy to use, has a locking function, and can cover the gaps after the folding table is stored.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a folding tabletop, comprising a base, wherein the base is hinged to two folding mechanisms arranged side by side, the folding mechanisms being used to store the tabletop into a box or unfold it, each folding mechanism including a first rotating arm and a second rotating arm hinged to each other, the second rotating arm being provided with the tabletop, both the base and the first rotating arm being provided with locking components, the locking components on the base being used to lock the first rotating arm, the locking components on the first rotating arm being used to lock the second rotating arm, the base also being hinged to a baffle, the width of the baffle being greater than the width of the two folding mechanisms arranged side by side, the baffle pressing against the folding mechanisms, and the baffle being linked to the first rotating arm of either folding mechanism.

[0006] Furthermore, the baffle is equipped with a hinged arm, which is hinged to the base via a hinge shaft. The hinge shaft and base are fixedly engaged. The hinged arm is equipped with a compression torsion spring to provide force to the baffle, ensuring it engages with the first rotating arm. One end of the compression torsion spring engages with the hinge shaft, and the other end engages with the hinged arm. The advantage is that the engagement of the hinge shaft and hinged arm ensures the reliability and smoothness of the baffle's rotation. The compression torsion spring provides sufficient force to keep the baffle engaged with the corresponding first rotating arm, reducing human intervention and improving linkage. Specifically, after the first baffle is retracted, it automatically follows and rotates to retract. When the first rotating arm rotates open, the baffle opens accordingly and engages with the first rotating arm, achieving automatic following and improving ease of use. Moreover, after the two folding mechanisms are retracted side-by-side, the baffle can cover the gap between them, preventing foreign objects from falling in.

[0007] Furthermore, the articulated arm is provided with an assembly cavity, the articulated shaft is fixed with an assembly located in the assembly cavity, the clamping torsion spring is sleeved on the outside of the assembly, the assembly is provided with a clamping groove that engages with one end of the clamping torsion spring, and the articulated arm is provided with a limiting groove that engages with the other end of the clamping torsion spring. The advantage is that by setting the assembly and the clamping torsion spring to cooperate, the reliability of the clamping torsion spring can be improved, and the unstable force caused by shaking during the rotation of the baffle can be avoided, especially during vehicle movement.

[0008] Furthermore, a soft pad is provided on the upper side of the baffle, and a buffer strip that contacts the folding mechanism is provided on the lower side of the baffle. The advantage is that the soft pad makes it easy for the folding mechanism to be stored, and the baffle and the armrest box work together to support the user's arm.

[0009] Furthermore, the first rotating arm is hinged to the base via a hinge shaft, and the locking assembly includes a locking pin. The first rotating arm is provided with a first arm locking groove. When the first rotating arm is in the locked state, the locking pin is inserted into the first arm locking groove. When the first rotating arm is in the unlocked state, the locking pin is separated from the first arm locking groove. The advantage is that the locking pin and the first arm locking groove can lock the first rotating arm, especially when the folding mechanism is in the retracted or unfolded state, thereby improving the stability of the folding table and preventing the table from being accidentally retracted during vehicle travel and from shaking after retracting.

[0010] Furthermore, the first arm locking groove includes a first arm unfolding groove and a first arm retracting groove. The first arm unfolding groove, the first arm retracting groove, the locking pin, and the rotation plane of the first arm are on the same plane. When the first rotating arm is in the unfolded state, the locking pin is inserted into the first arm unfolding groove. When the first rotating arm is in the retracted state, the locking pin is inserted into the first arm retracting groove. The advantage is that by setting the first arm unfolding groove, the first arm retracting groove, the locking pin, and the rotation plane of the first arm on the same plane, it can ensure that the locking pin has a strong locking ability for the first rotating arm. Setting the locking pin on the base can also effectively reduce the space occupied by setting it on other components, that is, the base has sufficient space and sufficient stability.

[0011] Furthermore, the first rotating arms of the two parallel folding mechanisms are hinged to the base via an integrally formed hinge shaft. The base is provided with a mounting part, which has mounting holes. The hinge shaft is inserted into the mounting holes, and the side wall of the mounting holes has a limiting groove. The hinge shaft is provided with a positioning element that cooperates with the limiting groove. The advantage is that the integrally formed hinge shaft connects the two parallel folding mechanisms, ensuring the balance of forces on both sides of the hinge shaft, especially during vehicle vibration and bumps. Moreover, the integrally formed hinge shaft effectively reduces space occupation. Compared with the traditional solution of setting two shafts to hinge the two first rotating arms, it has a smaller space occupation, simpler assembly process, and reduced production costs.

[0012] Furthermore, the first rotating arm is detachably provided with an auxiliary component, and the first locking groove is provided on the auxiliary component. The advantage is that the auxiliary component can effectively improve the service life and wear resistance of the first rotating arm. That is, the auxiliary component can be made of metal material, thereby reducing the wear rate between it and the locking pin, and can effectively improve the resistance to deformation, reduce the deformation accumulation when the user pries it open, and improve the service life.

[0013] Furthermore, the first rotating arm is provided with a mounting base, the mounting base is provided with an anti-pinch part and a connecting plate, the second rotating arm is provided with a rotating groove, and the connecting plate is hinged to the second rotating arm through a rotating shaft and located in the rotating groove. When the second rotating arm is in the unfolded state, the anti-pinch part and the rotating groove are opposite each other to cover the anti-pinch part. The second rotating arm is provided with a second arm unfolding groove that cooperates with the locking assembly. The advantage is that the anti-pinch part can effectively improve the safety of using the folding table and prevent the rotating groove from pinching hands, especially during the folding process of storing the folding table.

[0014] Furthermore, the tabletop includes a first shelf and a second shelf that can be folded or opened. The first shelf and the second shelf are hinged together by a hinge located on the lower side of the tabletop. The first shelf or the second shelf is mounted on a second rotating arm. When the first shelf and the second shelf are in the open state, the upper surface of the first shelf is flush with the upper surface of the second shelf. The advantage of installing the hinge on the lower side of the tabletop is that it ensures the flatness and aesthetics of the upper surface of the tabletop, reduces the gaps that exist in traditional solutions due to the hinge on the upper side, avoids pinching hands and objects, and improves reliability.

[0015] Compared with existing technologies, the present invention has the following advantages: The locking component reliably locks the folding mechanism of the folding table, preventing accidental folding and retraction after opening, reducing the probability of injury, especially during vehicle vibrations. Simultaneously, the baffle, which moves in conjunction with the folding component, effectively covers the gap between the two parallel first rotating arms, reducing the probability of hands being pinched during use. The baffle also prevents foreign objects from entering, reducing jamming of the first rotating arms due to obstructions, improving process flow and reliability. Because the baffle works in conjunction with the first rotating arms, the number of steps required for use is reduced. Users only need to open the table using the traditional folding table opening method; no manual operation of the baffle is required, as it can still be folded or opened along with the first rotating arms, improving ease of use.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.

[0035] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0036] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0037] As shown in Figures 1-17, a folding tabletop 9 includes a base 2. The base 2 is hinged to two parallel folding mechanisms 3. The folding mechanisms 3 are used to store the tabletop 9 into the housing 1 or unfold it. Each folding mechanism 3 includes a first rotating arm 3.1 and a second rotating arm 3.2 that are hinged together. The tabletop 9 is mounted on the second rotating arm 3.2 and is closed by a handrail cover 1.1 of the housing 1. When the folding mechanism 3 is flipped and unfolded, the handrail cover 1.1 cannot completely cover the entire folding mechanism 3, thus partially exposing it. The base 2 is installed inside the housing 1, and the tabletop 9 can be rotated out of the housing 1 via the folding mechanisms 3.

[0038] Both the base 2 and the first rotating arm 3.1 are provided with locking components 4. The locking components 4 on the base 2 are used to lock the first rotating arm 3.1, and the locking components 4 on the first rotating arm 3.1 are used to lock the second rotating arm 3.2. The base 2 is also hinged with a baffle 5. The width of the baffle 5 is greater than the width of the two folding mechanisms 3 arranged side by side. The baffle 5 is pressed on the folding mechanism 3, and the baffle 5 is linked and cooperates with the first rotating arm 3.1 of any folding mechanism 3.

[0039] Based on the above, a C-shaped hinge arm 5.1 is provided on the lower side of the baffle 5. One end of the hinge arm 5.1 is fixed to the baffle 5, and the other end of the hinge arm 5.1 is hinged to the base 2 through the hinge shaft 6. The hinge shaft 6 is fixedly engaged with the base 2. The hinge arm 5.1 is provided with a compression torsion spring 7 for providing force to the baffle 5 so that it fits against the first rotating arm 3.1. One end of the compression torsion spring 7 is engaged with the hinge shaft 6, and the other end is engaged with the hinge arm 5.1. To further explain, in order to ensure the reliability of the cooperation between the articulated arm 5.1 and the clamping torsion spring 7, an assembly cavity 5.2 is provided at the other end of the articulated arm 5.1. The articulated shaft 6 is fixed with an assembly 6.2 located in the assembly cavity 5.2. The clamping torsion spring 7 is sleeved on the outside of the assembly 6.2. The assembly 6.2 is provided with a clamping groove 6.3 that engages with one end of the clamping torsion spring 7. The articulated arm 5.1 is provided with a limiting groove 5.32.3 that engages with the other end of the clamping torsion spring 7. The cooperation between the assembly 6.2 and the clamping torsion spring 7 can improve the reliability of the clamping torsion spring 7 and avoid the instability of the force caused by the shaking during the rotation of the baffle 5, especially during vehicle operation. The cooperation between the hinge shaft 6 and the hinge arm 5.1 ensures the reliability and smoothness of the rotation of the baffle 5. The compression torsion spring 7 provides sufficient force to the baffle 5, ensuring it always engages with the corresponding first rotating arm 3.1, reducing human intervention and improving linkage. Specifically, after the first baffle 5 is retracted, it automatically rotates and retracts. When the first rotating arm 3.1 rotates open, the baffle 5 opens accordingly and comes into contact with the first rotating arm 3.1, achieving automatic following and improving ease of use. Furthermore, after the two folding mechanisms 3 are retracted side-by-side, the baffle 5 can cover the gap between them, preventing foreign objects from falling in.

[0040] It is worth mentioning that a soft pad 5.4 is provided on the upper side of the aforementioned baffle 5, and a buffer strip 5.5 is provided on the lower side of the baffle 5 to contact the folding mechanism 3. The soft pad 5.4 facilitates the folding mechanism 3 to be stored, and the baffle 5 and the armrest box work together to support the user's arm. At the same time, the aforementioned hinge arm 5.1 can optionally be integrally formed with the baffle 5, which can better improve the stability of the hinge arm 5.1 and the baffle 5. Of course, reinforcing ribs can also be provided on the hinge arm 5.1 to improve the resistance to deformation.

[0041] Preferably, to improve the stability of the rotation of the baffle 5, a stabilizer 8 is fixed on the base 2. The stabilizer 8 includes a stabilizer seat 8.1, which is fixed to the base 2. A gear 8.2 is rotatably mounted on the stabilizer seat 8.1, and a stabilizing tooth 5.6 that meshes with the gear 8.2 is provided at the lower end of the hinge arm 5.1. The stabilizer seat 8.1 can be a damper to prevent the baffle 5 from rotating too fast due to excessive pressure under the action of the compression torsion spring 7.

[0042] To improve the locking reliability of the folding mechanism 3, the first rotating arm 3.1 is hinged to the base 2 via the hinge shaft 6. The locking assembly 4 includes a locking pin 4.2. The first rotating arm 3.1 is provided with a first arm locking groove 3.16. When the first rotating arm 3.1 is in the locked state, the locking pin 4.2 is inserted into the first arm locking groove 3.16. When the first rotating arm 3.1 is in the unlocked state, the locking pin 4.2 is separated from the first arm locking groove 3.16. Specifically, the aforementioned first arm locking groove 3.16 includes a first arm unfolding groove 3.17 and a first arm retracting groove. The first arm unfolding groove 3.17, the first arm retracting groove, the locking pin 4.2, and the rotation plane of the first arm are on the same plane. When the first rotating arm 3.1 is in the unfolded state, the locking pin 4.2 is inserted into the first arm unfolding groove 3.17. When the first rotating arm 3.1 is in the retracted state, the locking pin 4.2 is inserted into the first arm retracting groove. By setting the first arm unfolding groove 3.17, the first arm retracting groove, the locking pin 4.2, and the rotation plane of the first arm on the same plane, it can be ensured that the locking pin 4.2 has a strong locking ability for the first rotating arm 3.1. Setting the locking pin 4.2 on the base 2 can also effectively reduce the space occupied by other components, that is, the base 2 has sufficient space and sufficient stability. The aforementioned locking pin 4.2 is movably disposed inside the locking seat 4.1, extending out of the locking seat 4.1. A compression spring for pressing the locking pin 4.2 is locked inside the locking seat 4.1.

[0043] An auxiliary component 3.15 is detachably mounted on the first rotating arm 3.1, and a first locking groove is disposed on the auxiliary component 3.15. This auxiliary component effectively improves the service life and wear resistance of the first rotating arm 3.1. Specifically, the auxiliary component 3.15 can be made of metal, thereby reducing the wear rate between it and the locking pin 4.2, and effectively improving its resistance to deformation, reducing the accumulation of deformation when the user manipulates it, and extending its service life. Alternatively, the first locking groove can be directly formed on the first rotating arm 3.1 instead of the auxiliary component 3.15.

[0044] It is worth mentioning that the first rotating arm 3.1 of the two folding mechanisms 3 arranged side by side can be assembled by two independent hinge shafts 6 and respectively hinged to the base 2. To further improve the stability of the rotation of the two folding mechanisms 3, save space, and reduce assembly steps, preferably, the first rotating arms 3.1 of the two parallel folding mechanisms 3 can be hinged to the base 2 via an integrally formed hinge shaft 6. The base 2 is provided with a mounting part 2.1, which has a mounting hole 2.2. The hinge shaft 6 is fixedly inserted into the mounting hole 2.2 and extends out at both ends. The two first rotating arms 3.1 are rotatably engaged with the two ends of the hinge shaft 6. A limiting groove 5.32.3 is provided on the side wall of the mounting hole 2.2. The hinge shaft 6 is provided with a positioning element 6.1 that cooperates with the limiting groove 5.32.3. To further improve the cooperation and fixing performance between the hinge shaft 6 and the base 2, a positioning hole 6.4 is provided in the middle of the hinge shaft 6. A positioning pin is screwed onto the base 2. The positioning pin passes through the positioning hole 6.4 and is fixed to the base 2.

[0045] To improve the reliability of the fit between the first rotating arm 3.1 and the second rotating arm 3.2, a mounting base 3.11 is provided on the first rotating arm 3.1, and a connecting plate 3.12 is provided on the mounting base 3.11. A connecting piece 3.21 is provided on the second rotating arm 3.2. The connecting plate 3.12 of the first rotating arm 3.1 and the connecting piece 3.21 of the second rotating arm 3.2 are rotatably fitted together via a rotating shaft 3.3. To ensure the reliability of the rotation between the first rotating arm 3.1 and the second rotating arm 3.2 and to achieve 90-degree rotation between them, a rotating groove 3.22 is provided on the second rotating arm 3.2. The connecting plate 3.12 and the connecting piece 3.21 are rotatably fitted together within the rotating groove 3.22. The rotating groove 3.22 results in a large exposed gap in the second rotating arm 3.2 after it is unfolded, which could easily injure the user or trap foreign objects. Therefore, an anti-pinch part 3.13 is provided on the mounting base 3.11. When the second rotating arm 3.2 is in the unfolded state, the anti-pinch part 3.13 and the rotating groove 3.22 are opposite each other to cover the anti-pinch part 3.13. The second rotating arm 3.2 is provided with a second arm unfolding groove 3.25 that cooperates with the locking assembly 4. When the second rotating arm 3.2 is in the retracted state, the second arm locking groove 3.24 on the second rotating arm 3.2 cooperates with the locking assembly 4 to lock the second rotating arm 3.2. The anti-pinch part 3.13 effectively improves the safety of using the folding table 9 and prevents fingers from being pinched by the rotating groove 3.22, especially during the retraction process of the folding table 9. A damping mechanism 10 can be provided at the aforementioned rotating shaft 3.3. The damping mechanism 10 includes a spring 10.1, a metal washer 10.2, and a POM washer 10.3. The hinge shaft 9.33 consists of bolts and nuts that are screwed together. The spring 10.1, metal washer 10.2, POM washer 10.3, connecting piece 3.21, and connecting plate 3.12 are all sleeved on the outside of the rotating shaft 3.3. The nut and bolt of the rotating shaft 3.3 can press the spring 10.1. The lateral force of the spring 10.1 acts on the connecting piece 3.21 and connecting plate 3.12 through the metal washer 10.2 and POM washer 10.3, thereby achieving a damping effect and realizing a damped rotation effect between the first rotating arm 3.1 and the second rotating arm 3.2.

[0046] To improve the stability of the folding mechanism 3 during storage and unfolding, a connecting rod 3.23 is hinged to the lower side of the second rotating arm 3.2, and a sliding groove 3.14 is provided on the first rotating arm 3.1. The other end of the connecting rod 3.23 is slidably disposed in the sliding groove 3.14. When the second rotating arm 3.2 is in the unfolded state, the lower end of the connecting rod 3.23 abuts against the lower side of the sliding groove 3.14, thereby improving the support performance of the second rotating arm 3.2.

[0047] The tabletop 9 of this invention includes a first shelf 9.1 and a second shelf 9.2 that can be folded or opened. The first shelf 9.1 and the second shelf 9.2 are hinged together by a hinge 9.3 located on the lower side of the tabletop 9. The first shelf 9.1 or the second shelf 9.2 is mounted on a second rotating arm 3.2. When the first shelf 9.1 and the second shelf 9.2 are in the open state, the upper side of the first shelf 9.1 is flush with the upper side of the second shelf 9.2. The hinge 9.3 includes a hinge member 9.31, and the two ends of the hinge member 9.31 are hinged to movable flaps 9.32 via hinge shafts 9.33. The movable flaps 9.32 are detachably fitted with the corresponding first shelf 9.1 and second shelf 9.2. A damping mechanism 10 is provided on the hinge shaft 9.33. The damping mechanism 10 includes a spring 10.1, a metal washer 10.2, and a POM washer 10.3. The hinge shaft 9.33 consists of a bolt and a nut that are screwed together. The ends of the spring 10.1, the metal washer 10.2, the POM washer 10.3, the movable leaf 9.32, and the hinge 9.31 are all sleeved on the outside of the hinge shaft 9.33. The nut and bolt of the hinge shaft 9.33 can press the spring 10.1. The lateral force of the spring 10.1 is applied to the movable leaf 9.32 and the hinge 9.31 through the metal washer 10.2 and the POM washer 10.3, thereby achieving a damping effect and enabling the first shelf 9.1 and the second shelf 9.2 to freely hover and rotate.
