DETAILED DESCRIPTION

[0040] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0041] In the description of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present application, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0042] Combine the following Figure 1-Figure 19 The table top assembly 100 and the vehicle 1000 having the table top assembly 100 according to an embodiment of the present application are described in detail.

[0043] Reference Figure 1-Figure 6As shown, the table top assembly 100 according to the embodiment of the present application includes a base 1, a table top 6, a table top connecting arm 5, a driving device 2 and a transmission device. One end of the table top connecting arm 5 is hingedly connected to the base 1, and the other end is hingedly connected to the table top 6. The table top connecting arm 5 drives the table top 6 to move through the transmission device. The driving device 2 is used to drive the table top connecting arm 5 to rotate relative to the base 1, and the transmission device drives the table top 6 to rotate relative to the table top connecting arm 5. In other words, the table top connecting arm 5 transmits the power of the driving device 2 to the table top 6 through the transmission device to drive the table top 6 to rotate. The table top 6 is not directly connected to the driving device 2, so that the movement of the table top 6 will not interfere with the driving device 2. The rotation direction of the table top 6 does not have to be the same as the rotation direction of the table top connecting arm 5, thereby achieving the degree of freedom in the arrangement of the table top 6.

[0044] Optionally, there is only one driving device 2. In this way, the number of driving devices 2 is small, which can save space and cost and make the structure of the table top assembly 100 simple.

[0045] Optionally, the driving device 2 can be installed on the base 1, so that the position of the driving device 2 is fixed on the base 1, so that the driving device 2 can better drive the table top connecting arm 5 to rotate.

When the table top connecting arm 5 rotates, the table top 6 is driven to rotate through the transmission device. There is no need to set up multiple driving devices 2, which is beneficial to cost saving. The overall structure is simple, which is beneficial to space saving.

When the driving device 2 drives the table board connecting arm 5 to rotate, the connecting arm gear 3 rotates with the table board connecting arm 5, and at the same time, the connecting arm gear 3 meshes with the base gear 4, the connecting arm gear 3 drives the interlaced gear 72 to rotate, and the interlaced gear 72 drives the support plate 7 to rotate synchronously when rotating, so that the rotation of the support plate 7 can be realized, and the rotation of the support plate 7 can drive the table board 6 to rotate, so that the position of the table board 6 is changed, and the table board 6 is adjusted to the storage position, the unfolded position and the intermediate position, wherein the "intermediate position" refers to any position between the storage position and the unfolded position.

[0048] In some embodiments of the present application, reference Figure 5 , Figure 11-13 As shown, a avoidance hole 53 is formed on the table top connecting arm 5 , and the staggered gears 72 are at least partially embedded in the avoidance hole 53 .

[0052] In some other embodiments not shown in the figures, the first key structure 33 may also be a spline.

[0053] In some embodiments of the present application, reference Figure 1 , Fig.13 As shown, a retaining spring 34 is installed at one end of the gear shaft 321 passing through the first connecting hole 51 and the gear hole 311, so that the relative axial positions of the first gear 31 and the second gear 32 are fixed.

[0054] In some embodiments of the present application, a slide groove 61 is provided on one of the table top 6 and the support plate 7 , and a limit block 71 is provided on the other one, and the limit block 71 can be slidably disposed in the slide groove 61 .

The stopper 71 is slidably disposed in the slide groove 61. In this way, when the support plate 7 rotates, the support plate 7 can drive the table top 6 to rotate relative to the table top connecting arm 5. A groove 62 is provided on the table top 6, a part of the support plate 7 is located in the groove 62, and the slide groove 61 is provided on the groove wall of the groove 62. Optionally, the stopper 71 can be provided on both sides of the support plate 7, and the slide groove 61 can be provided on the groove walls on opposite sides of the groove 62.

[0058] In some embodiments of the present application, reference Fig.11 , Figure 16-Figure 18 As shown, the driving device 2 includes a driving body 21 and a main shaft 22, the driving body 21 and the main shaft 22 are connected, and the main shaft 22 and the table board connecting arm 5 are driven by the second key structure 83. The table board connecting arm 5 is provided with a second connecting hole 52, the main shaft 22 extends into the second connecting hole 52, and a second key structure 83 is provided between the main shaft 22 and the second connecting hole 52, thereby enabling the main shaft 22 and the table board connecting arm 5 to rotate synchronously and stop rotating synchronously.

[0059] Optionally, the driving body 21 is a driving motor, and the table top 6 is driven by the motor to achieve unfolding or folding.

Figure 7 In the example, the spindle hole 222 is a waist-shaped hole.

[0063] In some embodiments of the present application, the hinge axis between the support plate 7 and the table top connecting arm 5 is parallel to the hinge axis between the table top 6 and the table top connecting arm 5. Figure 1-Figure 8 As shown, the hinge axis between the support plate 7 and the table board connecting arm 5 is the first hinge axis 81, and the hinge axis between the table board 6 and the table board connecting arm 5 is the second hinge axis 82. The first hinge axis 81 is parallel to the second hinge axis 82. Therefore, the rotation direction of the support plate 7 is the same as that of the table board 6, both are clockwise or both are counterclockwise.

[0064] In some embodiments of the present application, reference Figure 1 , Figure 3-Figure 5 , Fig.11 As shown, the table top connecting arm 5 is provided with a first axial hole 54 and a second axial hole 55, the first hinge axis 81 passes through the first axial hole 54, the second hinge axis 82 passes through the second axial hole 55, and the axes of the first axial hole 54 and the second axial hole 55 are parallel, so that the overall structure is more compact.

[0065] In some embodiments of the present application, reference Figure 1 , Figure 3-Figure 5 As shown, the base 1 includes a first base body 11 and a second base body 12, the second base body 12 is installed on the first base body 11, and the driving device 2 is installed on the second base body 12. The first base body 11 and the second base body 12 can be connected and fixed by a second fastener 85. Optionally, the second fastener 85 can be a bolt, a rivet, etc. By configuring the base 1 to include the first base body 11 and the second base body 12, the components can be dispersedly arranged on the first base body 11 and the second base body 12, making the overall structure more reasonable, and also facilitating the installation and disassembly operations of the entire table top assembly 100. Figure 1-Figure 6 In the example, the first base body 11 is provided with a first mounting hole 112, the second fastener 85 is a bolt, and the second fastener 85 passes through the first mounting hole 112 and is fastened to the second base body 12. Optionally, the number of the second fasteners 85 is multiple, such as two, three, four, etc.

[0066] In some embodiments of the present application, the driving body 21 of the driving device 2 can be mounted and fixed on the second seat body 12 by a first fastener 84. Optionally, the first fastener 84 can be a bolt, a rivet, etc. Figure 1 In the example, the driving body 21 is provided with a main body mounting hole 211, the second seat body 12 is provided with a second mounting hole 122, and the first fastener 84 passes through the main body mounting hole 211 and the second mounting hole 122. Optionally, the number of the second fasteners 85 is multiple, such as two, three, four, etc.

[0067] In some embodiments of the present application, a first limiting structure 111 is provided on the first seat body 11, and the first limiting structure 111 is used to limit the first limit position of the table board connecting arm 5. Figure 1-Figure 3 As shown, the table top connecting arm 5 abuts against the first limiting structure 111, and the table top connecting arm 5 is located at the first extreme position.

[0068] In some embodiments of the present application, a second limiting structure 121 is provided on the second base body 12, and the second limiting structure 121 is used to limit the second limit position of the table board connecting arm 5. Figure 3 , Figure 5-Figure 6 As shown, the second limiting structure 121 is constructed as a planar structure. When the table top connecting arm 5 abuts against the second limiting structure 121, the table top connecting arm 5 is located at the second extreme position.

[0069] The table top 6 is mainly driven by a driving motor. One end of the main shaft 22 is connected to the driving motor. The other end of the main shaft 22 can be supported in the inner hole 41 of the base gear 4. The base gear 4 is fixed to the first base body 11 through the flat boss hole 113 installed on the first base body 11 (such as Figure 1 and Fig. 9 ), the main shaft 22 is rigidly connected to the table connecting arm 5 through the second key structure 83 (such as Figure 11-Figure 12 ), the connecting arm gear 3 includes a first gear 31 and a second gear 32, the second gear 32 is rigidly connected to the first gear 31 through a first key structure 33 and a retaining spring 34, and is mounted on a rotatable table top connecting arm 5 (such as Figure 11-Figure 12 ), the staggered gear 72 is rigidly connected to the support plate 7 (such as Figure 14-15 ). When the table top 6 is in the initial position (such as Figure 6 ), the driving shaft of the driving motor is installed and connected through the waist-shaped main shaft hole 222 on the main shaft 22 (such as Figure 16-Figure 18 The table board connecting arm 5 is connected to the support plate 7 via a first hinge shaft 81, the table board connecting arm 5 is connected to the table board 6 via a second hinge shaft 82, and the support plate 7 is installed in the slide groove 61 of the table board 6 via two cylindrical limit blocks 71 at the front end (such as Figure 5 ).

[0070] When the table top 6 is unfolded, the table top connecting arm 5 rotates and the table top 6 stretches horizontally at the same time:

[0071] When the table top 6 needs to be unfolded, the driving body 21 drives the main shaft 22 to rotate and drive the table top connecting arm 5 to rotate positively around the rotation center. For example, the driving shaft of the driving body 21 starts to operate clockwise, and the driving main shaft 22 rotates clockwise, and at this time, the table top connecting arm 5 starts to rotate clockwise around the rotation center. While the table top connecting arm 5 rotates clockwise around the rotation center, the table top connecting arm 5 drives the first gear 31 to rotate synchronously around the base gear 4. When the first gear 31 rotates, it will drive the second gear 32 to rotate, thereby driving the staggered gear 72 meshing with the second gear 32 to rotate. The staggered gear 72 is rigidly connected to the support plate 7. The staggered gear 72 drives the support plate 7 to rotate relative to the table top connecting arm 5 around the first hinge axis 81. When the support plate 7 rotates, it will pull the table top 6 to rotate relative to the table top connecting arm 5 around the second hinge axis 82. When the support plate 7 rotates, it slides along the slide groove 61 on the table top 6. When the table top connecting arm 5 rotates clockwise to 90° around the rotation center, it is limited by the first limiting structure 111 on the side of the first base body 11. When the table top connecting arm 5 is fully extended, the support plate 7 rotates by driving the first gear 31 to rotate when the table top connecting arm 5 rotates. When the support plate 7 rotates around the first hinge shaft 81 by a certain angle (for example, 60°), the other end of the support plate 7 slides in the slide groove 61 of the table top 6, pulling the table top 6 to rotate 90° around the second hinge shaft 82 to a horizontal position, that is, the unfolded position (such as Figure 3-Figure 4 shown).

[0072] When the table top 6 is stored, the table top connecting arm 5 rotates and the table top 6 is retracted at the same time:

[0073] When the table top 6 needs to be stored, the driving body 21 drives the main shaft 22 to rotate, driving the table top connecting arm 5 to rotate in the opposite direction around the rotation center. For example, the driving shaft of the driving body 21 starts to operate counterclockwise, the driving main shaft 22 rotates counterclockwise, and the table top connecting arm 5 starts to rotate counterclockwise around the rotation center. When the table top connecting arm 5 rotates counterclockwise around the rotation center, the table top connecting arm 5 drives the first gear 31 to rotate synchronously around the base gear 4. When the first gear 31 rotates, it will drive the second gear 32 to rotate, thereby driving the staggered gear 72 to rotate. The staggered gear 72 is rigidly connected to the support plate 7. The staggered gear 72 drives the support plate 7 to rotate relative to the table top connecting arm 5 around the first hinge axis 81. While the support plate 7 rotates, it slides along the slide groove 61 on the table top 6. When the support plate 7 rotates, it will pull the table top 6 to rotate relative to the table top connecting arm 5 around the second hinge axis 82. When the table top connecting arm 5 rotates counterclockwise around the rotation center, the table top 6 is also gradually retracted by the rotation of the first gear 31 driven by the rotation of the table top connecting arm 5. When the table top connecting arm 5 rotates 90° counterclockwise around the rotation center, it is limited by the second limiting structure 121 of the second base body 12. At this time, the table top connecting arm 5 is completely retracted, and the support plate 7 is rotated by driving the first gear 31 to rotate when the table top connecting arm 5 is retracted. When the support plate 7 rotates in the opposite direction around the first hinge shaft 81 by a certain angle (for example, 60°), the other end of the support plate 7 slides in the slide groove 61 of the table top 6, pulling the table top 6 to rotate in the opposite direction around the second hinge shaft 82 by 90° to the storage position (for example, Figure 5-Figure 6 shown).

[0074] In other embodiments, Figure 3-Figure 4 The position of the table top 2 shown can be the storage position. Figure 5-Figure 6 The position of the table top 2 shown may be the unfolded position.

[0077] According to the vehicle 1000 of the embodiment of the present application, the driving device 2 of the table top assembly 100 drives the table top connecting arm 5 to rotate. When the table top connecting arm 5 rotates, the table top 6 is driven to rotate through the transmission device. There is no need to set up multiple driving devices 2, which is beneficial to cost saving. The overall structure is simple, which is beneficial to space saving.
