Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted equipment, in particular to a table top assembly and a vehicle with the same. Background Art

[0002] With the continuous development of social economy, the continuous improvement of people's living standards and the increasingly mature functions of automobiles, people pay more and more attention to the comfort of riding. At present, a folding table is usually installed in the central control armrest box of the car to provide users with a convenient office and entertainment environment, optimize the driving experience, and meet the diverse needs of users when riding.

[0003] like Figure 1-Figure 3 As shown, the prior art has developed a tabletop assembly 2. The tabletop 3 of the tabletop assembly 2 can be flexibly unfolded to the left or right side of the central control armrest box 1 as needed, so that only one set of tabletop assembly 2 can meet the needs of users on both sides at the same time, greatly reducing the cost of components and saving storage space in the central control armrest box 1. However, in actual use, this tabletop assembly 2 often needs to be stored on one side in a specific order. For example, see Figure 2 Only when the table top 2 is rotated to the left side of the entire table top assembly 1 can it be normally stored in the central control armrest box 1. Figure 3 When the user does not follow the correct storage order and rotates the table top 2 to the right side of the entire table top assembly 1, the table top 2 will extend out of the central control armrest box 1. At this time, if the user makes an error and tries to store the table top 2 into the central control armrest box 1, the table top 2 is very likely to interfere with surrounding components (such as the central control armrest box 1), greatly reducing the user's experience.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0005] In order to solve or improve to a certain extent the technical problem in the prior art that interference easily occurs when the table top assembly is stored, the utility model provides a table top assembly. The table top assembly includes: a base; a transmission mechanism, which includes a first transmission part and a second transmission part connected to each other, the first transmission part is rotatably arranged on the base, the second transmission part is configured to be rotatable around the center line of the first transmission part to switch between a first rotation position and a second rotation position opposite to each other, and the transmission mechanism is configured to switch between a working position and a storage position when the second transmission part is in the first rotation position; a table top assembly, which is rotatably fixed on the second transmission part and configured to have different rotation directions corresponding to the first rotation position and the second rotation position; and a locking mechanism, which is arranged on the transmission mechanism and configured to cooperate with the second transmission part when the second transmission part is in the second rotation position to constrain the transmission mechanism to the working position.

[0006] It can be understood by those skilled in the art that the tabletop assembly of the utility model includes a base, a transmission mechanism, a tabletop assembly and a locking mechanism. Among them, the transmission mechanism includes a first transmission part and a second transmission part connected to each other. The first transmission part is rotatably arranged on the base, and the second transmission part can rotate around the center line of the first transmission part so as to switch between a first rotation position and a second rotation position that are opposite to each other. The tabletop assembly is rotatably fixed on the second transmission part, and has different rotation directions corresponding to the first rotation position and the second rotation position of the second transmission part. In this way, by controlling the different rotation positions of the second transmission part, the tabletop assembly can be unfolded in different directions to meet the use needs of different users. The locking mechanism is arranged on the transmission mechanism. When the second transmission part is in the first rotation position, the transmission mechanism can switch between the relative working position and the storage position; and when the second transmission part is in the second rotation position, the locking mechanism matches the second transmission part so that the transmission mechanism can only be limited to the working position. Therefore, the table top assembly of the utility model can not only realize single-sided storage, but also can effectively avoid user misoperation even if the user does not store it in the prescribed order, and prevent the table top assembly from interfering with surrounding components (such as the central control armrest box, etc.) during the storage process, thereby improving the user experience.

[0007] In the preferred technical solution of the above-mentioned table top assembly, the table top assembly is configured to rotate relative to the second transmission part when the second transmission part is in the first rotation position, and drive the locking mechanism to switch between the locking position and the unlocking position; and the second transmission part is configured to constrain the locking mechanism to the locking position when it is in the second rotation position. When the second transmission part is in the first rotation position, the table top assembly can not only rotate relative to the second transmission part, but also drive the locking mechanism to switch between the relative locking position and the unlocking position, thereby allowing the entire transmission mechanism to switch between the working position and the storage position. When the second transmission part is in the second rotation position, the second transmission part can cooperate with the locking mechanism so that the locking mechanism is constrained in the locking position, thereby limiting the transmission structure to the working position to avoid user's misoperation.

[0008] In the preferred technical solution of the table top assembly, the locking mechanism includes a locking rod, and a locking hole is provided on the base, wherein when the locking mechanism is in the locking position, the locking rod is inserted into the locking hole; when the locking mechanism is in the unlocking position, the locking rod is disengaged from the locking hole. Through the cooperation of the locking hole and the locking rod, the locking mechanism can be conveniently locked and unlocked relative to the base.

[0009] In the preferred technical solution of the table top assembly, a connecting cavity is formed in the first transmission part and the second transmission part respectively, and the locking rod is telescopically arranged in the connecting cavity. Through the above arrangement, the structure of each component can be made more compact, and the first transmission part and the second transmission part can also be used to protect the locking rod to a certain extent.

[0010] In the preferred technical solution of the table top assembly, a connecting shaft connected to the first transmission part and a rotating sleeve connected to the second transmission part are respectively provided in the connecting cavity; and a first stop post and a second stop post spaced apart from each other along its circumference are formed on the connecting shaft, and a third stop post is formed on the rotating sleeve, wherein when the second transmission part is in the first rotation position, the third stop post abuts against the first stop post; when the second transmission part is in the second rotation position, the third stop post abuts against the second stop post. Through the above arrangement, the second transmission part can be accurately rotated to the corresponding first rotation position and second rotation position, ensuring the reliability and stability of the components.

[0011] In the preferred technical solution of the table top assembly, the locking rod is provided with a first locking head close to the table top assembly, and a first guide groove and a second guide groove connected to each other are formed on the first locking head; and a locking protrusion extending vertically outward is formed on the inner wall of the rotating sleeve, wherein when the second transmission part is in the first rotation position, the locking protrusion is constrained in the first guide groove; when the second transmission part is in the second rotation position, the locking protrusion is constrained in the second guide groove. Through the cooperation of the locking protrusion with the first guide groove and the second guide groove, the second transmission part can selectively constrain the locking rod in the locking position.

[0012] In the preferred technical solution of the above-mentioned table top assembly, the first guide groove extends in a direction parallel to the center line, and the second guide groove extends in a direction around the center line. The first guide groove is configured to extend in a direction parallel to the center line, so that when the locking protrusion on the rotating sleeve is constrained in the first guide groove, the locking rod can smoothly extend and retract in the direction of the center line. The second guide groove is configured to extend in a direction around the center line, so that when the locking protrusion of the rotating sleeve is constrained in the second guide groove, the locking rod is stably confined in the locking position, so that the transmission mechanism is correspondingly constrained in the working position, and will not rotate to the storage position due to the user's misoperation.

[0013] In the preferred technical solution of the table top assembly, the locking mechanism further comprises a reset elastic member located between the first locking head and the connecting shaft. The reset elastic member is arranged so that when the restraining force on the locking rod is released, it can automatically reset under the elastic action of the reset elastic member itself.

[0014] In the preferred technical solution of the table top assembly, a first micro switch is provided in the locking hole, wherein when the transmission mechanism is in the working position, the locking rod is configured to trigger the first micro switch; when the transmission mechanism is in the storage position, the locking rod is configured to avoid triggering the first micro switch. Through the above arrangement, the position and state of the locking mechanism and the transmission mechanism can be accurately known.

[0015] In the preferred technical solution of the table top assembly, a second locking head close to the base and having an escape groove is provided on the locking rod, and a second micro switch is also provided in the locking hole, wherein when the second transmission part is in the first rotation position, the second micro switch extends into the escape groove and is in an untriggered state; when the second transmission part is in the second rotation position, the second micro switch is disengaged from the escape groove and is triggered by the second locking head. Through the above arrangement, the position and state of the second transmission part can be accurately known.

[0016] In the preferred technical solution of the table top assembly, the table top assembly includes a connecting plate rotatably arranged on the second transmission part and a table top body connected to the connecting plate. Through the above arrangement, the degree of freedom of the table top body can be improved, which is convenient for storage.

[0017] In the preferred technical solution of the above-mentioned table top assembly, the table top body can be foldably arranged on the connecting plate to further save the space occupied by the table top body and facilitate storage.

[0051] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0053] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In order to solve or improve to some extent the technical problem that the table top assembly in the prior art is prone to interference when being stored, the utility model provides a table top assembly 100. The table top assembly 100 includes: a base 110; a transmission mechanism 120, which includes a first transmission part 121 and a second transmission part 122 connected to each other, the first transmission part 121 is rotatably arranged on the base 110, the second transmission part 122 is configured to be rotatable around the center line C of the first transmission part 121 to switch between a first rotation position and a second rotation position opposite to each other, and the transmission mechanism 120 is configured to switch between a working position and a storage position when the second transmission part 122 is in the first rotation position; a table top assembly 130, which is rotatably fixed on the second transmission part 122 and configured to have different rotation directions corresponding to the first rotation position and the second rotation position; and a locking mechanism 140, which is arranged on the transmission mechanism 120 and configured to cooperate with the second transmission part 122 when the second transmission part 122 is in the second rotation position to constrain the transmission mechanism 120 in the working position.

[0055] like Figure 4-Figure 11 As shown, in one or more embodiments, the table top assembly 100 of the utility model includes components such as a base 110, a transmission mechanism 120, a table top assembly 130 and a locking mechanism 140. Among them, the base 110 provides a suitable installation space for components such as the transmission mechanism 120, the table top assembly 130 and the locking mechanism 140. The base 110 is suitable for being fixed in the central control armrest box of the vehicle or other suitable positions. In one or more embodiments, a locking hole 111 is opened on the base 110 to match the locking rod 141 in the locking mechanism 140.

[0056] like Figure 4-Figure 11 As shown, the transmission mechanism 120 is rotatably fixed on the base 110. The transmission mechanism 120 has a relative storage position and a working position. In the assembled state, when in the storage position, the transmission mechanism 120 extends substantially along the X direction (i.e., the front and rear direction) of the vehicle (not shown in the figure); see Figure 4-Figure 11 When in the working position, the transmission mechanism 120 extends substantially along the Z direction (ie, the up and down direction) of the vehicle.

[0057] like Figure 4-Figure 11As shown, in one or more embodiments, the transmission mechanism 120 includes a first transmission part 121 and a second transmission part 122 connected to each other. The first transmission part 121 is rotatably arranged on the base 110. The second transmission part 122 can rotate around the center line C of the first transmission part 121 to rotate between the first rotation positions (see Figure 4-Figure 7 ) and the second rotational position (see Figure 8-Figure 11 ). When the second transmission part 122 is in the first rotation position, the transmission mechanism 120 is configured to be convertible between the storage position and the working position, and when the second transmission part 122 is in the second rotation position, the transmission mechanism 120 is constrained in the working position and cannot be rotated to the storage position to prevent users from misoperating.

[0058] like Figure 5 , Figure 7 , Fig. 9 , Fig.11 , Fig.13 and Fig.14 As shown, in one or more embodiments, a connecting shaft 124 is formed on the first transmission part 121, and a rotating sleeve 125 matched with the connecting shaft 124 is formed on the second transmission part 122. The connecting shaft 124 extends substantially along the center line C of the first transmission part 121. One end of the connecting shaft 124 is fixed in the first transmission part 121, and the other end extends into the second transmission part 122. The second transmission part 122 can rotate in a clockwise direction or a counterclockwise direction around the connecting shaft 124, so that the second transmission part 122 can rotate equivalent to the first transmission part 121. A first stop column 1241 and a second stop column 12412 spaced apart from each other in the circumferential direction are formed on the end of the connecting shaft 124 close to the second transmission part 122, and a third stop column 1251 is formed on the rotating sleeve 125. When the second transmission part 122 is in the first rotation position, the third stop post 1251 abuts against the first stop post 1241; when the second transmission part 122 is in the second rotation position, the third stop post 1251 abuts against the second stop post 12412. Through the above arrangement, the second transmission part 122 can be accurately rotated to the corresponding first rotation position and second rotation position, ensuring the reliability and stability of the components. In one or more embodiments, the first stop post 1241 and the second stop post 12412 are spaced 180° apart from each other in the circumferential direction, so that the first rotation position and the second rotation position are opposite to each other. In other words, the second transmission part 122 can be rotated from Figure 6 After the first rotation position shown is rotated 180° in the positive direction, it is converted to Figure 8 Correspondingly, the second transmission part 122 can also be changed from Figure 8 After the second rotation position shown is rotated 180° in the opposite direction, it is converted to Figure 6 The first rotational position is shown.

[0059] Continue to see Figure 5 , Figure 7 , Fig. 9 and Fig.11 In one or more embodiments, a hollow connecting cavity 123 is formed in the first transmission part 121 and the second transmission part 122, respectively. The connecting cavity 123 extends substantially along the center line C of the first transmission part 121, and can be communicated with the locking hole 111 on the base 110. The connecting cavity 123 can receive the locking rod 141 in the locking mechanism 140, and allow the locking rod 141 to move therein so as to cooperate with the locking hole 111. Further, the connecting shaft 124 is arranged in the connecting cavity 123, and the connecting shaft 124 has a hollow structure, so that the locking rod 141 in the locking mechanism 140 can be telescopically fixed in the connecting shaft 124.

[0060] like Figure 4-Figure 11 As shown, the table top assembly 130 is rotatably arranged on the second transmission part 122. The table top assembly 130 has different rotation directions corresponding to the first rotation position and the second rotation position. Figure 4-Figure 7 , when the second transmission part 122 is in the first rotation position, the tabletop assembly 130 can be rotated to the right side of the transmission mechanism 120; when the second transmission part 122 is in the first rotation position, the tabletop assembly 130 can be rotated to the left side of the transmission mechanism 120. Therefore, the tabletop assembly 100 of the utility model can meet the use needs of different users at the same time, reduce component costs, and save space. In addition, when the second transmission part 122 is in the first rotation position, the tabletop assembly 130 can also drive the locking mechanism 140 to switch between the locking position and the unlocking position during the rotation relative to the second transmission part 122, thereby allowing the transmission mechanism 120 to switch between the working position and the storage position. It should be pointed out that the user can also adjust the angle between the second transmission part 122 and the first transmission part 121 in the transmission mechanism 120 according to actual needs (that is, the second transmission part 122 is at other positions between the first rotation position and the second rotation position), so that the rotation direction of the tabletop assembly 130 is more flexible to better meet the use needs of the user.

[0061] Continue to see Figure 4 , Figure 6 , Figure 8 and Fig.10In one or more embodiments, the table top assembly 130 includes a connecting plate 131 and a table top body 132 connected to each other. Among them, the connecting plate 131 is rotatably arranged on the second transmission part 122. Through the above-mentioned arrangement, the table top body 132 can have a higher degree of freedom and is easy to store. In one or more embodiments, the table top body 132 can be foldably arranged on the connecting plate 131 to further save the space occupied by the table top body 132. For example, the table top body 132 includes a first table top and a second table top (not shown in the figure) that are pivotally connected to each other. A hinge or other suitable components can be used to form a pivotal connection between the first table top and the second table top.

[0062] like Figure 4-Figure 11 As shown, the locking mechanism 140 is arranged on the transmission mechanism 120. Figure 4-Figure 7 When the second transmission part 122 is in the first rotation position, the locking mechanism 140 can be driven by the table top assembly 130 to be in the locking position (see Figure 6-Figure 7 ) and unlocked position (see Figure 4-Figure 5 ). Figure 8-Figure 11 When the second transmission part 122 is in the second rotational position, the locking mechanism 140 is configured to cooperate with the second transmission part 122 so that the locking mechanism 140 is constrained in the locking position, thereby constraining the transmission mechanism 120 in the working position.

[0063] like Figure 4-Figure 11 As shown, the locking mechanism 140 includes a locking rod 141. The locking rod 141 is telescopically arranged in the connecting cavity 123 of the transmission mechanism 120. More specifically, the locking rod 141 is telescopically arranged in the hollow connecting shaft 124. Figure 4-Figure 5 When the locking mechanism 140 is in the unlocking position, the locking rod 141 is disengaged from the locking hole 111. Figure 6-Figure 11 When the locking mechanism 140 is in the locking position, the locking rod 141 is inserted into the locking hole 111 .

[0064] Continue to see Figure 4-Figure 12 The locking rod 141 has a rod body (not marked in the figure) extending substantially along the center line C of the first transmission part 121. In one or more embodiments, a substantially semicircular protrusion (not marked in the figure) is formed at the top of the rod body so as to match with the connecting plate 131 of the table board assembly 130.

[0065] Continue to see Fig.12In one or more embodiments, a first locking head 1411 close to the table top assembly 130 is further provided on the rod body. A first guide groove 14111 and a second guide groove 14112 connected to each other are formed on the first locking head 1411. In one or more embodiments, the first guide groove 14111 extends substantially in a direction parallel to the center line C of the first transmission part 121, and the second guide groove 14112 extends in a direction around the center line C. Specifically, based on Fig.12 In the orientation shown, the first guide groove 14111 extends substantially in the up-down direction; the second guide groove 14112 extends circumferentially to the right from the upper end of the first guide groove 14111 (i.e., the end away from the base 110). The central angle of the second guide groove 14112 may be 90° or other suitable angles. Fig.13 and Fig.14 A locking protrusion 1252 extending vertically outward is formed on the inner wall of the rotating sleeve 125 so as to cooperate with the first guide groove 14111 and the second guide groove 14112 .

[0066] See also Figure 5 , Figure 7 , Fig. 9 , Fig.11 and Fig.14 In one or more embodiments, the locking mechanism 140 further includes a reset elastic member 142 located between the first locking head 1411 and the connecting shaft 124. The reset elastic member 142 may be, but is not limited to, a spring. The reset elastic member 142 can be provided so that when the restraining force on the locking rod 141 is released, the reset elastic member 142 can be used to drive the locking rod 141 to automatically reset by utilizing the elastic action of the reset elastic member 142 itself.

[0067] like Figure 4-Figure 7 When the second transmission part 122 is in the first rotation position, the locking protrusion 1252 on the rotating sleeve 125 is constrained in the first guide groove 14111, so that the entire locking rod 141 can rise or fall along the direction of the center line C of the first transmission part 121. The connecting plate 131 forms a substantially eccentric structure at a position close to the locking rod 141. Therefore, when the connecting plate 131 is moved from the folded position (such as Figure 4 and Figure 5 as shown) to the expanded position (as shown) Figure 6 and Figure 7When the connecting plate 131 rotates from the unfolded position to the folded position, the eccentric structure on the connecting plate 131 can gradually release the pressure applied to the locking rod 141. In this process, the originally compressed reset elastic member 142 automatically stretches under its own elastic action, and pops the locking rod 141 out of the locking hole 111, so that the locking mechanism 140 is transformed from the locked position to the unlocked position, and then the transmission mechanism 120 is allowed to transform from the working position to the storage position.

[0068] like Figure 8-Figure 11 When the second transmission part 122 is in the second rotation position, the rotating sleeve 125 rotates with the second transmission part 122 and is constrained in the second guide groove 14112. At this time, the locking rod 141 is always inserted into the locking hole 111 of the base 110, and the locking mechanism 140 remains in the locked position. Therefore, when the connecting plate 131 is rotating, whether it is from the unfolded position (such as Figure 8 and Fig. 9 ) to the folded position (eg Fig.10 and Fig.11 ), or rotated from the folded position to the unfolded position, since the locking protrusion 1252 on the rotating sleeve 125 is always inserted into the second guide groove 14112 on the first locking head 1411, the locking mechanism 140 is always in the locked position, and the entire transmission mechanism 120 is constrained in the working position. Fig.10 and Fig.11 The second transmission part 122 cannot be rotated to the storage position from the working position shown in the figure, thereby preventing the table top assembly 130 from colliding with surrounding parts (such as the central control armrest box, etc.) due to user's misoperation. In this case, if the user wants to smoothly switch the transmission mechanism 120 to the storage position, the second transmission part 122 needs to be rotated to the first rotation position first, and then the table top assembly 130 needs to be rotated to the storage position as shown in the figure. Figure 4 and Figure 5 The position shown causes the locking mechanism 140 to switch to the unlocking position, and finally the transmission mechanism 120 is rotated from the working position to the storage position to complete the storage of the entire table top assembly 100.

[0069] like Figure 5 , Figure 7 , Fig. 9 , Fig.11 and Fig.15In one or more embodiments, the table top assembly 100 of the utility model further includes a first micro switch 150. The first micro switch 150 is arranged in the locking hole 111. When the transmission mechanism 120 is in the working position, the locking rod 141 of the locking mechanism 140 is inserted into the locking hole 111 of the base 110. At this time, the locking rod 141 is configured to trigger the first micro switch 150. When the transmission mechanism 120 is in the storage position, the locking rod 141 of the locking mechanism 140 is disengaged from the locking hole 111, and the locking rod 141 is configured to avoid triggering the first micro switch 150. Through the above-mentioned settings, the position and status of the locking mechanism 140 and the transmission mechanism 120 can be accurately known, providing data support for monitoring and using the table top assembly 100.

[0070] like Fig.12 As shown, in one or more embodiments, a second locking head 1412 is formed at one end of the rod body of the locking rod 141 away from the first locking head 1411. In the assembled state, the second locking head 1412 is close to the base 110. The second locking head 1412 is formed with an avoidance groove 14121 extending substantially in a direction parallel to the center line C of the first transmission part 121. Fig.15 In one or more embodiments, a second micro switch 160 is further provided in the locking hole 111 of the base 110. When the second transmission part 122 is in the first rotation position, the second micro switch 160 extends into the avoidance groove 14121 and is in an untriggered state. When the second transmission part 122 is in the second rotation position, the second micro switch 160 is disengaged from the avoidance groove 14121 and is triggered by the second locking head 1412. Through the above-mentioned configuration, the position and state of the second transmission part 122 can be accurately known, providing data support for monitoring and using the table top assembly 100.

[0071] In one or more embodiments, the utility model further provides a vehicle (not shown in the figure). The vehicle includes the table assembly 100 described in any of the above embodiments. The vehicle also includes a central control armrest box (not shown in the figure), and the table assembly 100 is arranged in the central control armrest box. The central control armrest box can be located between the second row of seats or other suitable positions.
