Description

Technical Field

[0001] The present application relates to a table device for a vehicle and a structural component for a vehicle including the table device. Background Art

[0002] Table devices for vehicles are known in practice, which can be provided, in particular, on the backrest of a vehicle seat. Some known table devices have a support independent of the backrest, by means of which the table of the table device can have a horizontal orientation in the use position. However, such a support needs to occupy a certain space behind the vehicle seat in the use position of the table device, and the support in the use position limits the adjustment range of the inclination angle of the backrest. Some known table devices have a defined use position on the backrest. When the inclination angle of the backrest is adjusted, the table in the defined use position changes its angle together with the inclination angle of the backrest and will deviate from the horizontal orientation. Therefore, in the case of such a table device, either the inclination angle of the backrest is non-adjustable or the table device is only available at a specific inclination angle of the backrest.

[0071] Multiple exemplary embodiments will now be described more fully with reference to the accompanying drawings. It should be appreciated that elements that are not necessary for understanding the present utility model may be omitted from the drawings for purposes of illustration and understanding. In the drawings, the same reference numerals may represent the same components or components with the same functions. In the following description, numerous specific details such as examples of specific components, devices, and methods are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It will be apparent to those skilled in the art that not all of these specific details need necessarily be employed. The exemplary embodiments should not be construed as restrictive.

[0072] Figures 1 to 4 There is shown a vehicle seat 100 according to a first embodiment of the present utility model. The vehicle seat 100 includes a seat portion 101 and a backrest 102, and the vehicle seat 100 includes a table device 200 according to a first embodiment of the present utility model, which is directly mounted on the back side of the backrest 102. In the state as Figure 1 shown, the vehicle seat 100 is in the designed position, and the backrest 102 of the vehicle seat 100 has a predetermined inclination angle, for example, an angle of approximately 15° backward with respect to the vertical line. In the designed position, a user, such as a driver or an occupant on the passenger seat, can sit comfortably on the vehicle seat and attentively focus on the surrounding environment or traffic conditions of the vehicle. Here, the table 10 is in the stowed state, and the visible side surface of the table 10 can be substantially coplanar with the back side of the backrest 102. In the state as Figure 2 shown, the vehicle seat 100 is still in the designed position, but the table 10 is now adjusted from the stowed state to the open state, wherein the table 10 is positioned substantially horizontally. A user behind the vehicle seat 100, such as an occupant on the rear seat, can use the table 10, for example, can place a laptop or a tablet computer on the table 10. In the state as Figure 3 shown, the inclination angle of the backrest of the vehicle seat 100 is adjusted backward from the designed position, for example, an angle of approximately 30° backward with respect to the vertical line. Through the adjustment of the table device 200, especially an automatic and adaptive adjustment, the table 10 remains in the horizontal open state. In the state as Figure 4 shown, the inclination angle of the backrest of the vehicle seat 100 is adjusted forward from the designed position, for example, an angle of approximately 0° with respect to the vertical line. Similarly, through the adjustment of the table device 200, especially an automatic and adaptive adjustment, the table 10 still remains in the horizontal open state. As Figures 2 to 4 clearly visible, when the inclination angle of the backrest 102 of the vehicle seat 100 is adjusted, through the corresponding adjustment of the table device 200, especially an automatic and adaptive adjustment, the table 10 can still remain in the horizontal open state. Corresponding to Figures 2 to 4 that, Figures 7 to 9 are respectively shown in side views Figure 1Side view of the frame of the backrest 102 of the vehicle seat 100 and the frame of the table device 200, wherein the backrest 102 has different inclination angles and the table 10 is always in a horizontal open state.

[0073] In the sense of the present utility model, the "horizontal open state" can be understood as the predetermined substantially horizontal orientation of the table. For example, in some designs, according to actual needs, the edge of the table 10 facing the user can be slightly raised relative to the edge of the table 10 facing the vehicle seat, so as to facilitate preventing the objects placed on the table 10 from slipping towards the user.

[0074] In some application scenarios, instead of the substantially horizontal positioning of the table, it is also possible that in the predetermined open state of the table 10, the table 10 can have a predetermined inclination angle, in which case, a smartphone or a tablet computer can be suitably placed on the table 10, and the user can comfortably watch the video files played through the smartphone or the tablet computer, or can comfortably operate the smartphone or the tablet computer.

[0075] As Figures 5 to 11 shown, the table device 200 includes a linkage mechanism, a table motor 30 and a controller 50. The linkage mechanism is coupled to the table 10. The table motor 30 is configured to drive the linkage mechanism, and the controller 50 is configured to control the table motor 30 so as to adjust the table device 200 when the inclination angle of the backrest 102 of the vehicle seat 100 is adjusted while the table 10 is in the open state, so as to maintain the substantially horizontal positioning of the table 10. When the table 10 is in the retracted state, the linkage mechanism is in the first posture. When the table 10 is in the horizontal open state, the linkage mechanism is in another posture different from the first posture. In principle, the table motor 30 can be various motors, but preferably it is also a Hall motor.

[0076] Here, the controller 50 can be configured as a separate control unit. Alternatively, the controller 50 can also be integrated in the table motor 30. Alternatively, the controller 50 can also be integrated in the controller (not shown) of the vehicle seat 100. Particularly advantageously, the controller 50 can be in signal connection with the Hall motor 103, as will be described in more detail below. The signal connection between the controller 50 and the Hall motor 103 can be realized in various forms, for example, the two are directly connected, or connected through a CAN bus, or the connection is realized in the domain control system of the vehicle.

[0077] Here, the linkage mechanism can be configured as a four-bar linkage 20. The four-bar linkage 20 includes a first link 21 located above and a second link 22 located below. Each of a first end 21a and 22a of the first link 21 and the second link 22 is connected to the backrest 102 of the vehicle seat 100, and each of a second end 21b and 22b of the first link 21 and the second link 22 is connected to the table 10. In the exemplary embodiment shown in the figure, the four-bar linkage 20 includes a pair of first links 21 arranged side by side and a pair of second links 22 arranged side by side. However, it is also possible that only a single first link 21 and a single second link can be provided; or three or more first links 21 arranged side by side and three or more second links 22 arranged side by side can be provided. The number of the first links 21 and the number of the second links 22 can be the same or different from each other.

[0078] In an advantageous embodiment, as Figure 11 shown, a base plate 104 and a pair of mounting brackets 23 can be provided. The pair of mounting brackets 23 can be fastened to the base plate 104 by fastening elements. Each mounting bracket 23 mates with one first link 21 and one second link 22, wherein each mounting bracket 23 is connected to the first end 21a of the corresponding first link 21 and the first end 22a of the corresponding second link 22. In an alternative, not shown embodiment, the mounting bracket can be an integrally formed member with the base plate, wherein the integrated base plate can have a connection plate, which can perform the same function as the above-mentioned mounting bracket. In another alternative, not shown embodiment, a single substantially U-shaped integral mounting bracket can be provided, and the integral mounting bracket can be mounted to the base plate 104. The two legs of the integral mounting assembly can perform the same function as the above-mentioned pair of mounting brackets 23.

[0079] A pair of second linkages 22 can be interconnected by a synchronization member such that the pair of second linkages 22 move synchronously. Here, the synchronization member is configured as a rotary shaft 40, and the rotary shaft 40 is torsionally connected to each first end 22a of the pair of second linkages 22. The tabletop motor 30 is in driving connection with the rotary shaft 40. The tabletop motor 30 can be mounted to the base plate 104. The tabletop motor 30 has an output gear 34, and the output gear 34 meshes with a toothed sector 41 torsionally provided on the rotary shaft 40. Through the meshing of the output gear 34 and the toothed sector 41, the tabletop motor 30 can drive the rotary shaft 40 to rotate, and thereby can synchronously drive the pair of second linkages 22. The first motor mounting plate 31 and the second motor mounting plate 32 can be sleeved on the rotary shaft 40 and are provided on both sides of the toothed plate 41. The first motor mounting plate 31 is adjacent to the tabletop motor 30. The first motor mounting plate 31 and the second motor mounting plate 32 can be fastened to the flange plate 33 of the tabletop motor 30 by a fastening device, such as a threaded connection device 38 including bolts 38a and nuts 38b. The output shaft of the tabletop motor 30 having the output gear 34 passes through the first motor mounting plate 31, and the free end of the output shaft is supported by the second motor mounting plate 32. The tabletop motor 30 can further include a positioning pin 39, and the positioning pin can pass through corresponding positioning holes in the first motor mounting plate 31 and the second motor mounting plate 32. The positioning pin 39 can have a thread at its free end, and a mating nut 39a can be screwed onto the thread of the positioning pin 39 from the side of the second motor mounting plate 32 facing away from the tabletop motor 30. The second motor mounting plate 32 can include a bottom section 32a, two opposed side legs 32b bent from the bottom section 32a in the direction of the first motor mounting plate 31, and abutting sections 32c bent outwardly from the two side legs 32b respectively. The second motor mounting plate 32 abuts against the first motor mounting plate 31 with the two abutting sections 32c. The free end of the output shaft of the tabletop motor 30 is supported by the bottom section 32a of the second motor mounting plate 32, and the output gear 34 of the tabletop motor 30 is received in the receiving space defined by the first motor mounting plate 31 and the second motor mounting plate 32.

[0080] At least one spring 35, for example two helical torsion springs, can be provided on the rotating shaft 40. The springs pre-tension the rotating shaft 40 to eliminate the meshing clearance between the output gear 34 of the table motor 30 and the toothed sector 41. A corresponding retaining member 36 for the spring 35 can be provided on the rotating shaft 40. One end of the spring 35 can be fixed to the retaining member 36, and the other end of the spring 35 can be fixed, for example, to the substrate 104. The rotating shaft 40 can be provided with a limiting mechanism for limiting the angular range of the rotating shaft 40 and thus the movement range of the table 10 of the table device 200. In the illustrated embodiment, the rotating shaft 40 can have a follower finger 37 that extends into the positioning window 105. The positioning window 105 limits the movement range of the follower finger 37 and thus the angular range of the rotating shaft 40. The positioning window 105 can advantageously be provided in the substrate 104.

[0081] In a particularly advantageous embodiment, as Figure 5 shown, the vehicle seat 100 can be equipped with a Hall motor 103. The Hall motor 103 is configured to drive the vehicle seat 100, in particular to drive the backrest 102 of the vehicle seat 100, for adjusting the inclination angle of the vehicle seat 100, in particular the inclination angle of the backrest 102. The controller 50 of the table device 200 can be in signal connection with the Hall motor 103 so as to obtain the signal wave of the Hall motor 103 when adjusting the inclination angle of the vehicle seat 100 by the Hall motor 103, and thus obtain the current inclination angle of the backrest 102 of the vehicle seat 100, and then control the table motor 30 when using the table device 200 such that the table 10 of the table device 200 reaches or remains in a substantially horizontal open state. By utilizing the electrical signal of the Hall motor 103, a separate inclination angle sensor can be omitted.

[0082] Reference Figure 11 and Figure 12 illustrate some details of the table device 200. The table 10 of the table device 200 can include a table skeleton 13, an upper cover plate 11, and a lower cover plate 12. The upper cover plate 11 and the lower cover plate 12 can be connected to each other to sandwich the table skeleton 13 between the upper cover plate 11 and the lower cover plate 12. The first link 21 and the second link 22 are respectively hinged to the table skeleton 13 at their second ends 21b, 22b. The first link 21 and the second link 22 are respectively hingedly connected to the mounting bracket 23 and the table skeleton 13 at their two ends through corresponding connecting devices 26.

[0083] An intelligent panel assembly 14 (see Figure 11 ) can be provided in the table 10. For this purpose, wires 25 for power supply and signal transmission (see Figure 12)From the backrest 102 of the vehicle seat 200, it is guided to the intelligent panel assembly 14 in the table board 10 through the guiding groove opened in the second link 22.

Here, direct transmission can be achieved between the output gear 34 of the table board motor 30 and the tooth fan 41 of the rotating shaft 40. The entire table board device 200 can have a compact structure and a small number of parts. Here, it is possible that the table board motor 30 and the rotating shaft 40 can be pre-assembled into a structural unit.

[0085] Next, with reference to Figures 15 to 21 The vehicle seat 100 according to the second embodiment of the present invention will be described.

Therefore, the controller 50 of the table board device 200 is also in signal connection with the Hall motor 103 of the vehicle seat 100.

[0087] In the second embodiment, the tabletop motor 30 is mounted above the rotating shaft 40, and the rotating shaft 40 also serves as a synchronization member to connect the first ends 22a of a pair of second linkages 22 to each other. Here, the tabletop motor 30 is configured as a lead screw motor, and the lead screw motor includes a lead screw nut mechanism 60 as a pushing mechanism. By the pushing and pulling of the pushing mechanism, the tabletop motor 30 can rotate the rotating shaft 40 in two opposite rotational directions. The lead screw nut mechanism 60 includes a lead screw 61 that can be driven to rotate and a nut 62 that meshes with the lead screw 61. Instead of the nut 62, a threaded sleeve can also be used. The tabletop device 200 may have a pair of transmission rods 42 fixedly connected to the rotating shaft 40, and the nut 62 is rotatably connected to the pair of transmission rods 42. As Figures 15 to 17 shown, when the tabletop 10 is in the retracted state, the pair of transmission rods 42 extend upward from the rotating shaft 40 and away from the tabletop 10.

[0088] A support member extending substantially horizontally can be provided between the upper ends of the pair of mounting brackets 23. For example, the support member can be configured as a support rod or a support tube 53, which is welded to the pair of mounting brackets 23. A U-shaped first motor bracket 51 can be fixed, especially welded, on the support member or on the support tube 53. The first motor bracket 51 has opposite side plates 56 (see Figure 19 ). Particularly advantageously, the first motor bracket 51 can be disposed centrally on the support member. The U-shaped second motor bracket 52 has opposite side plates, and the upper side plate has a pair of flanges 55 at its opposite edges. Each flange 55 is connected to a side plate 56 of the first motor bracket 51 by fastening elements 54 (such as rivets, screws, step bolts, pins or the like), so that the second motor bracket 52 is rotatable relative to the first motor bracket 51 about a first pivot axis A1. The tabletop motor 30 is mounted in the second motor bracket 52. Here, the fastening elements 54 define the first pivot axis A1 (see Figure 19 ). The fastening elements 43 connecting the nut 62 to the pair of transmission rods 42 define a second pivot axis A2 (see Figure 18 ). The first pivot axis A1, the second pivot axis A2, and the rotating shaft 40 extend parallel to each other.

[0089] Particularly advantageously, as Figure 17 shown, when the tabletop 10 is in the retracted state, the first linkage 21 contacts the first end 22a of the second linkage 22. Therefore, in the retracted state of the tabletop 10, during the driving operation of the vehicle, the tabletop device 200 is not easily affected by vibrations. Although Figure 17 shows the case of the four-bar linkage 20 of the tabletop device 200 according to the second embodiment, it goes without saying that this also applies to the four-bar linkage 20 of the tabletop device 200 according to the first embodiment.

[0090] In addition, particularly advantageously, asFigure 6 , Figures 9 to 11 As shown in Figures 9 to 11 , at the maximum open position of the tabletop 10, the first link 21 contacts the second end 22b of the second link 22. Thereby, the tabletop 10 can be clearly limited. Although these drawings show the four-link mechanism 20 of the tabletop device 200 according to the first embodiment, it goes without saying that the same also applies to the four-link mechanism 20 of the tabletop device 200 according to the second embodiment.

[0091] The tabletop device 200 according to the second embodiment may have the following advantages: The tabletop motor 30 can be arranged below the cross beam 107 of the backrest 102 and adjacent to the cross beam 107, and this position has sufficient space to accommodate the tabletop motor 30. Thus, in principle, the tabletop device 200 can be installed without changing, especially without increasing the thickness dimension of the backrest 102, which is beneficial for the manual tabletop and the electric tabletop to share the same seat shape. In addition, the arrangement of the tabletop motor 30 in this recess can meet the requirements of collision safety, ensure the safety distance between the occupant and the internal metal parts of the seat during a collision accident, and reduce the risk of injury to the occupant.
