Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicles, in particular to a table board assembly and a vehicle comprising the same. BACKGROUND

[0002] With the development of automobile intelligence, the interior trim parts are also more and more intelligent, providing convenience for the use of drivers and passengers. For example, the folding table board function can be highly integrated with the automobile interior, which not only facilitates the user's office and entertainment needs without affecting the aesthetics, but also improves the luxury of the vehicle interior, thus becoming a field of competition for major automobile manufacturers.

[0003] However, most of the current folding table boards are arranged at the backrest of the front seats or in the large armrest of the rear seats. For the table board arranged at the backrest of the front seats, it usually needs to be manually operated to open or store, and cannot provide intelligent convenience. For the table board arranged in the armrest, such as the automatic table board system disclosed in the existing patent No. CN201821371029.0, although it can realize the automatic opening function of the table board, the operation is relatively cumbersome, that is, the user needs to open the armrest cover first to start the table board system in the armrest. The entire process of folding the table board out of the armrest and then folding it takes a long time, which is not conducive to the quick use of the table board. Similarly, the process of storing the table board also takes a long time, which is not conducive to saving the user's time. Moreover, in terms of structure, the table board of the above-mentioned patent needs to be configured with two sets of motors to drive a series of actions, which is relatively complex to configure and consumes a lot of energy, which is not conducive to the control of development cost.

[0004] Therefore, for the current folding table board, it is not conducive to the simplification of the structure and the use convenience is not enough, and still needs to be improved. CONTENT OF THE INVENTION

[0051] As Figures 1 to 12As shown, this application provides a tabletop assembly, including a tabletop 10 and a base plate 11. The base plate 11 is slidably connected to the tabletop 10 and disposed at the bottom of the tabletop 10, and the tabletop 10 can slide relative to the base plate 11 in the front-back direction. A base 12 is disposed below the base plate 11, and the base plate 11 is rotatably connected to the base 12, allowing the base plate 11 to rotate relative to the base 12. A connecting rod 13 is disposed between the base 12 and the base plate 11, with its rear end rotatably connected to the base 12 and its front end disposed at... The tabletop 10 has a first connecting part 131, a first mating part 101 at the bottom of the tabletop 10, and a clearance groove 111 extending vertically along the front-back direction of the base plate 11. The first connecting part 131 and the first mating part 101 are axially connected through the clearance groove 111. The tabletop 10 is rotated while the base plate 11 is rotated. The tabletop 10 rotates while the connecting rod 13 rotates. The first connecting part 131 and the first mating part 101 slide along the clearance groove 111, causing the tabletop 10 to slide relative to the base plate 11.

[0052] The tabletop 10 of this application has the function of automatically rotating and sliding outward relative to the base plate 11 to reach the use position, which can meet the user's intelligent and convenient needs. Users do not need to manually open or put away the tabletop 10, freeing up their hands and improving the user experience. While rotating, the tabletop 10 can slide outward to provide more usable space, which can meet the user's needs for dining, working or entertainment. Moreover, the rotation and sliding of the tabletop 10 are carried out simultaneously, and the entire process from the initial position to the use position is short, providing the function of quick use and storage of the tabletop 10, saving users time and greatly improving the convenience of use.

[0053] The table assembly can be directly installed at the armrest position. Before the table 10 rotates, its surface can be used as an armrest. When the user needs to dine, work, or entertain, the table 10 simply needs to rotate to the user's position, thus enriching the table 10's functionality. Moreover, the table assembly has a simple structure, requiring only one drive assembly for power, resulting in low energy consumption, which helps save development costs and improves the table assembly's versatility in most vehicle models.

[0054] Specifically, such as Figure 2 As shown, the table 10 is in its initial position. When the table assembly is positioned in the vehicle's armrest area, the table 10 is located to the side of the user in its initial position. When the button or key on the table 10 is activated, the table 10 rotates to adjust its orientation. When the table 10 reaches its intended use position, as shown... Figure 3 As shown, the tabletop 10 can now be positioned in front of the user, allowing the user to perform activities on it. Furthermore, as... Figure 3 or Figure 4As shown, when the tabletop 10 is in the use position, the tabletop 10 slides outward relative to the base plate 11, so that the one-button operation can simultaneously realize the rotation and sliding action of the tabletop 10, freeing the user's hands, increasing the usable area of ​​the tabletop 10, and improving the convenience and comfort of use.

[0055] It is understandable that the rotation radius of the tabletop 10 is defined as r1, where r1 is the distance between the central axis of the first mating part 101 and the central axis of the rotating shaft 14 of the base plate 11, and the distance between the central axes of the rotating positions at both ends of the connecting rod 13 is r2 (in the example where the connecting rod 13 has a first connecting part 131 and a second connecting part 132 at both ends, r2 is the distance from the central axis of the first connecting part 131 to the second connecting part 132). By setting r1 < r2, while the base plate 11 drives the tabletop 10 to rotate towards the user, the front end of the connecting rod 13 can push the tabletop 10 to slide outward relative to the base plate 11, that is, the first connecting part 131 and the first mating part 101 slide along the avoidance groove 111, thereby realizing the function of rotating and sliding out of the tabletop 10. Figure 1 and Figure 2 In the example, the rear end of the base plate 11 is rotatably connected to the base 12, and the clearance groove 111 is provided on the front side of the rotating structure of the base plate 11, so that when the table 10 rotates, it can slide out along the clearance groove 111 in a direction away from the base plate 11. Figure 1 and Figure 2 The front-to-back direction is consistent with the front-to-back direction of the vehicle, with the front of the vehicle as the front and the rear as the rear. When the table assembly is in its initial position, the end facing the front of the vehicle is considered the front, and the end facing the rear of the vehicle is considered the rear.

[0056] In one exemplary embodiment, such as Figure 1 As shown, the first connecting part 131 is a collar, and the first mating part 101 is a cylindrical insertion post. The insertion post extends downward and can pass through the clearance groove 111 to insert into the collar to achieve a axial connection. It is understood that the structure of the first connecting part 131 and the first mating part 101 is not limited to the above-described manner. For example, in other embodiments, the first connecting part 131 can be an upwardly extending insertion post, and the first mating part 101 can be a collar. The upwardly extending insertion post can pass through the clearance groove 111 to insert into the collar to achieve a axial connection. This application does not limit the specific form of the first connecting part 131 and the first mating part 101; they can be flexibly set according to actual needs to improve the flexibility of structural design.

[0057] The table assembly of this application can be located at the armrest position inside the vehicle, such as at the front and / or rear armrest position. This application does not limit the location and can be set according to actual needs.

[0058] After using the tabletop 10, the user can activate the drive component to return the tabletop 10 from the used position to the initial position. This process is the reverse of opening the tabletop 10, and the principle of operation is similar, so it will not be described in detail here.

[0059] In a preferred embodiment of this application, the base plate 11 is slidably connected to the tabletop 10 on both sides in the left and right directions, the clearance groove 111 is centered in the left and right directions relative to the base plate 11, and the first mating part 101 is centered in the left and right directions relative to the tabletop 10.

[0060] In this embodiment, by centrally positioning the clearance groove 111 and the first mating part 101, the force applied to the tabletop 10 by the connecting rod 13 during the sliding process of the tabletop 10 can be evenly distributed relative to the tabletop 10, so that the tabletop 10 slides more smoothly. At the same time, it avoids the tabletop 10 from easily tilting on its left and right sides when the force is uneven, which could cause the tabletop 10 to slide stuck or affect the stability of the tabletop 10 in the final use position.

[0061] In one embodiment, the sliding structure between the base plate 11 and the tabletop 10 can be, for example: Figure 8 and Figure 9 As shown, the tabletop 10 has first sliding grooves 105 on both sides, and the base plate 11 has slide rails 113 on both sides. The relative movement between the tabletop 10 and the base plate 11 is achieved by sliding the slide rails 113 along the first sliding grooves 105. It is understood that the sliding structure between the base plate 11 and the tabletop 10 is not limited to the above method. For example, in other embodiments, sliders can be provided on both sides of the tabletop 10, and sliding grooves can be provided on both sides of the base plate 11, with the sliders sliding within the grooves to achieve the relative movement between the tabletop 10 and the base plate 11.

[0062] like Figure 1 As shown, the first mating part 101, the avoidance groove 111, and the first connecting part 131 are arranged from top to bottom. In this embodiment, by centrally arranging these components relative to the left and right sides of the tabletop 10, the connecting rod 13 can push the tabletop 10 outward more easily and smoothly. Compared with the tabletop 10 being force-bearing from one side, the tabletop 10 requires less power from the motor of the drive component, which helps to save energy. Moreover, it can ensure the sliding speed of the tabletop 10 and avoid the tabletop 10 sliding too slowly or getting stuck, thus affecting the user's quick use.

[0063] In a preferred embodiment of this application, the bottom of the base plate 11 is provided with a downwardly extending pivot 14, the rear end of the base 12 is provided with a first pivot hole 15 that is axially connected to the pivot 14, the rear end of the connecting rod 13 is provided with a second connecting part 132, the base 12 is provided with a second mating part 121, the second connecting part 132 and the second mating part 121 are axially connected, the second mating part 121 is located on one side of the first pivot hole 15, the connecting rod 13 includes a first connecting arm 133 and a second connecting arm 134 that is bent and connected to the first connecting arm 133. In the initial position of the table 10, the first connecting arm 133 is located in front of the first pivot hole 15 and the second connecting arm 134 is located on one side of the first pivot hole 15 in the left-right direction.

[0064] In this embodiment, the connecting rod 13 adopts a bent configuration, which can make reasonable use of the space on the base 12 for arrangement, so as to avoid structures such as the rotating shaft 14 and the first shaft hole 15, ensuring that the components are arranged compactly, avoiding interference between components, and improving space utilization.

[0065] Combination Figure 2 and Figure 7 When the first shaft hole 15 occupies a large space at the rear end of the base 12, the second connecting arm 134, positioned on one side of the first shaft hole 15, can avoid interference with the fit between the rotating shaft 14 and the first shaft hole 15. Meanwhile, the front end of the base 12 has sufficient space to accommodate the first connecting arm 133, and this allows the first connecting arm 133 to extend towards the center of the left and right sides of the base 12. In the preferred embodiment, the first connecting portion 131 and the first mating portion 101 are centered relative to the left and right sides of the tabletop 10, thus improving the smoothness of the tabletop 10's sliding. Figure 2 and Figure 7 In the illustrated scheme, at the initial position of the tabletop 10, the second linkage arm 134 is located to the right of the first shaft hole 15. This orientation is only one possible scenario. In actual products, depending on the position of the tabletop assembly on the armrest, at the initial position of the tabletop 10, the second linkage arm 134 can also be located to the left of the first shaft hole 15, achieving the same avoidance effect as described above. Furthermore, as... Figure 3 As shown, when the tabletop 10 is rotated to the use position, the connecting rod 13 rotates outward along with the tabletop 10.

[0066] In one exemplary embodiment, such as Figure 10 and Figure 11As shown, the second connecting part 132 is a collar, and the second mating part 121 is a cylindrical insertion post, with the collar fitted onto the outside of the insertion post. To improve the reliability of the shaft connection between the second connecting part 132 and the second mating part 121, the insertion post is further provided with a shaft hole. By inserting a rotating shaft through the collar and the shaft hole, the connection effect of the second connecting part 132 and the second mating part 121 can be improved. It is understood that the structure of the second connecting part 132 and the second mating part 121 is not limited to the above-described manner. For example, in other embodiments, the second connecting part 132 can be an insertion post, and the second mating part 121 can be a collar, to improve the flexibility of the structural design.

[0067] Furthermore, in one embodiment, the first connecting portion 131 is disposed at the end of the first connecting arm 133, and the second connecting portion 132 is disposed at the end of the second connecting arm 134, with the first connecting portion 131 being higher than the second connecting portion 132.

[0068] In this embodiment, the first connecting part 131 is higher than the second connecting part 132, which is beneficial for the first connecting part 131 to be axially connected to the first mating part 101 above it, and can reduce the downward protrusion of the first mating part 101. At the same time, it is also beneficial for the second connecting part 132 to be axially connected to the second mating part 121 below it, thereby realizing the intermediate support function of the connecting rod 13, improving the convenience of installation at both ends of the connecting rod 13 and ensuring that both ends of the connecting rod 13 can be stably and reliably connected to the corresponding components.

[0069] like Figure 11 As shown, in an exemplary embodiment, the second linkage arm 134 includes a first segment 1341 and a second segment 1342. The first segment 1341 and the second segment 1342 are connected by a step portion 1343. The second segment 1342 is higher than the first segment 1341. The first linkage arm 133 is connected to the second segment 1342 and the two are set at the same horizontal height. This allows the first connecting portion 131 on the first linkage arm 133 to be higher than the second connecting portion 132 on the first segment 1341. Since the first connecting portion 131 is at a higher position, it is convenient to install the first mating portion 101 above it. Moreover, when the first mating portion 101 is a plug-in post, it is beneficial to shorten the length of the plug-in post in order to simplify the structure of the tabletop 10.

[0070] It is understood that the connecting rod 13 is not limited to a bent configuration. In other embodiments, the connecting rod 13 may also adopt a straight arm structure or an arc structure, depending on the distribution of the connecting rod 13 on the base 12, the connection position of the connecting rod 13 and the table 10, etc., so as to avoid interference between the connecting rod 13 and the surrounding components while making reasonable use of space, provided that the connecting rod 13 drives the table 10 to slide.

[0071] As a preferred embodiment of this application, the front end of the avoidance groove 111 is provided with a stop part 112. At the maximum corner position of the table 10, the first connecting part 131 abuts against the stop part 112 and is limited.

[0072] In this embodiment, such as Figure 2 and Figure 3 As shown, when the first connecting part 131 and the first mating part 101 slide to the front end of the avoidance groove 111, they reach the use position of the table 10. At this time, the first connecting part 131 abuts against the stop part 112 and is limited, and the table 10 completes the unfolding action. This can ensure that the table 10 remains stable during subsequent use, and prevent the table 10 from continuing to slide outward during use, which would affect the user's use and improve the reliability of use.

[0073] Preferably, the stop portion 112 has an arc-shaped stop surface that is adapted to the arc-shaped wall of the first connecting portion 131. When the first connecting portion 131 abuts against the stop portion 112, the two can fit together well, thereby reducing friction and impact between the components and helping to extend the service life of the structure.

[0074] In a preferred embodiment of this application, the drive assembly includes a motor (not shown in the figure) and a vertically arranged first gear 16 driven by the motor. A horizontally arranged second gear 17 is provided at the bottom of the base plate 11. The base 12 is provided with a vertically penetrating first shaft hole 15. The second gear 17 is exposed through the first shaft hole 15 so that the first gear 16 and the second gear 17 mesh and cooperate.

[0075] In this embodiment, when the function of the table 10 is needed, the motor drives the first gear 16 to rotate, and at the same time, the first gear 16 drives the second gear 17 to rotate, thereby realizing the rotation of the table 10. Only one set of drive components is required, which is simple to configure. Moreover, the power output through gear transmission is stable, which is conducive to the table 10 rotating at a uniform speed and smoothly, avoiding accidental hitting of people due to excessively fast rotation or requiring users to wait for a long time due to excessively slow rotation. Since the first gear 16 is arranged vertically and the drive shaft 161 of the first gear 16 extends to the side, the motor can be arranged to the side of the armrest position, rather than necessarily to the bottom of the armrest position, which improves the flexibility of motor installation and optimizes the utilization of vehicle interior space and component arrangement.

[0076] Preferably, the outer diameter of the tooth structure of the second gear 17 can be set to be slightly larger, so that the tabletop 10 can be rotated to the use position with fewer rotations of the second gear 17. Of course, the outer diameter of the tooth structure of the second gear 17 can also be set to be slightly smaller, in which case the second gear 17 needs to rotate more times to reach the use position when the tabletop 10 is rotated.

[0077] It is understood that in other embodiments, the drive component includes a motor, the base plate 11 is provided with a rotating shaft, the rotating shaft of the base plate 11 can be directly driven by the motor to realize the rotation of the base plate 11, and a coupling can be provided between the motor and the rotating shaft to improve the transmission effect.

[0078] In one embodiment, a second shaft hole 122 is provided on one side of the bottom of the base 12, the drive shaft 161 of the first gear 16 is axially connected to the second shaft hole 122, and the drive shaft 161 passes through the second shaft hole 122 to be connected to the motor drive.

[0079] In this embodiment, the base 12 provides the conditions for the installation of the first gear 16. The first gear 16 is directly installed on the base 12, which not only facilitates meshing with the second gear 17 but also improves the compactness of the structure. The structure for installing the first gear 16 can be omitted, simplifying the structural configuration and making the overall structure of the table assembly compact, thus avoiding taking up too much space in the vehicle.

[0080] like Figure 2 , Figure 10 , Figure 12 As shown, the second shaft hole 122 is located on the left side of the base 12, and the drive shaft 161 can rotate within the second shaft hole 122. The outward-facing end of the drive shaft 161 is provided with a coupling hole 162, which can be connected to the motor output shaft. Furthermore, the right side of the base 12 is provided with a second mating part 121, which is used to axially connect with the second connecting part 132 of the connecting rod 13. By placing the second shaft hole 122 on the left side of the base 12, the motor can be arranged on the left side of the base 12. Therefore, when the tabletop 10 rotates towards the right side of the base 12, interference with the motor can be avoided, achieving a reasonable structural distribution.

[0081] As a preferred embodiment of this application, a baffle beam 102 extending in the left-right direction is provided at the bottom front side of the table 10. At the initial position of the table 10, the front end of the bottom plate 11 abuts against the baffle beam 102.

[0082] In this embodiment, such as Figure 2 and Figure 3 As shown, by setting the retaining beam 102, during the installation of the base plate 11, when the base plate 11 is inserted along the bottom of the tabletop 10, the front end of the base plate 11 can be abutted against the retaining beam 102 to ensure that the base plate 11 is inserted in place, thus improving installation efficiency; during the sliding and retraction of the tabletop 10 relative to the base plate 11, the tabletop 10 is retracted when it slides to the front end of the base plate 11 and abuts against the retaining beam 102, which helps to maintain the stability of the tabletop 10 and the base plate 11 together, and avoids relative movement between the two when not in use, thereby improving the reliability of use.

[0083] In a preferred embodiment of this application, the tabletop 10 includes a main board 103 and an extension board 104, with a base plate 11 housed in the main board 103 and the extension board 104 protruding forward relative to the base plate 11.

[0084] In this embodiment, the base plate 11 is housed in the main plate 103, which helps to save space and improve the compactness of the structure. By setting the extended extension plate 104, the usable area of ​​the tabletop 10 can be further expanded, providing users with a more comfortable user environment, which can meet the requirements for dining, working or entertainment.

[0085] like Figure 2 and Figure 3 As shown, preferably, the length of the main board 103 is the same as the length of the base plate 11. In the initial position of the tabletop 10, the base plate 11 can be completely retracted into the main board 103, minimizing space occupation. The extension plate 104 lengthens the tabletop 10, providing advantageous conditions for users to place more or larger items. For example... Figure 4 As shown, after the tabletop 10 slides out, the overall length of the tabletop 10 plus the length of the exposed base plate 11 greatly increases the usable area of ​​the tabletop 10, which can improve the user experience.

[0086] As a preferred embodiment of this application, the tabletop 10 has an initial position and a usage position. The tabletop 10 rotates from the initial position to the usage position by a first angle, the first angle being in the range of 80°-100°.

[0087] In this embodiment, when the table 10 reaches the use position, the table 10 is located in front of the user. In order to accommodate users of different body types, the range of rotation angles can be reasonably set. For example, when the first angle is 80°, the table 10 has a large gap from the user's chest when in the use position, which can prevent the table 10 from being too close to the user and causing discomfort. When the first angle is 100°, the table 10 has a small gap from the user's chest when in the use position, so that it can be closer to the user with a smaller body type or even when the user is leaning against the back of the seat, so as to easily reach the table 10, thereby improving the comfort of use.

[0088] Figure 5 This is a schematic diagram showing the tabletop 10 rotating to a certain position in the middle. The tabletop 10 continues to rotate until it reaches... Figure 6 When the tabletop 10 is in the working position, in this embodiment, the tabletop 10 is rotated 90° from the initial position to reach the working position. Preferably, the first angle is 90°. At this time, the tabletop 10 is horizontally positioned in front of the user for convenient use. Of course, in other embodiments, the first angle can also be 80°, 85°, 95°, 100°, etc. The tabletop 10 has a certain tilt angle when in the working position, but it does not affect the user's use.
