Description

Technical Field

[0001] This utility model relates to the field of automotive seat components technology, specifically to an electrically adjustable backrest table. Background Technology

[0002] As people's living standards improve, consumers have increasingly higher requirements for the quality of car interiors. To meet these diverse needs, more and more car models are equipping seat tray tables as standard or optional features. Seat tray tables enhance passenger comfort and convenience. They are typically installed behind the front seats, are foldable, and flexible in use, suitable for work, reading, entertainment, and more.

[0003] Traditional electric tray table drive mechanisms are usually located inside the backrest. These mechanisms take up a lot of space and can significantly affect the arrangement of other modules inside the backrest. In addition, they can also cause the backrest foam to become thinner, affecting the comfort of the ride. Utility Model Content

[0004] In view of this, the present invention provides an electrically adjustable backrest table, which solves the problem of the large space occupied by the drive mechanism inside the backrest.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An electrically adjustable backrest table includes a table body connected to a transmission assembly. The transmission assembly allows the table body to be flipped and mounted on the back of a seat. The table body has an integrated drive mechanism that drives the transmission assembly to rotate the table body between an unfolded position and a folded position.

[0007] With the above structure, the drive mechanism is integrated inside the small table and connected to the back of the seat via a transmission component. This does not occupy the internal space of the backrest, does not affect the arrangement of the internal modules of the seat back, and ensures the comfort of the passengers.

[0008] Preferably, the drive mechanism includes a slider reciprocally mounted within the small table body and a synchronizing rod rotatably mounted within the small table body. A rocker arm extending radially outward is fixed to the synchronizing rod, and a connecting rod is hinged to one end of the rocker arm. The other end of the connecting rod is rotatably connected to the slider. The synchronizing rod is connected to the transmission assembly. The drive mechanism also includes a power assembly for driving the slider to reciprocate. With this structure, the drive mechanism is arranged horizontally along the small table, resulting in a compact structure.

[0009] Preferably, the power assembly includes a motor fixed inside the small table body and a lead screw driven by the motor, with the slider threadedly connected to the lead screw. This structure provides power, driven by the lead screw, allowing the device to hover and bear force at any position, and can withstand greater loads and abuse.

[0010] Preferably, the small table body has a hollow mounting chamber inside, and the hollow mounting chamber is provided with two sets of sliding grooves parallel to the length direction of the lead screw. The two ends of the slider are slidably disposed in the sliding grooves. This structure facilitates installation.

[0011] Preferably, the transmission assembly includes a mounting component and a first transmission rod and a second transmission rod rotatably connected to both ends of the mounting component. The end of the first transmission rod away from the mounting component is rotatably connected to the small table body, and the end of the second transmission rod away from the mounting component is fixedly connected to the synchronizing rod. The mounting component is used to fix the small table to the back of the seat. This structure facilitates the folding and unfolding of the small table.

[0012] Preferably, a torsion spring is fitted onto the synchronizing rod, with its two ends supported on the rocker arm and the small table body, respectively. This structure enhances the stability of the small table.

[0013] Preferably, the rocker arms and connecting rods are in two sets, symmetrically arranged on both sides of the slider. This structure ensures that the slider is subjected to balanced forces.

[0014] Preferably, the synchronizing rod is a square shaft with a sleeve fixedly fitted in its middle, and the two sets of rocker arms are mounted on the sleeve. This structure ensures synchronization.

[0015] Preferably, there are two sets of the first and second transmission rods, symmetrically arranged on both sides of the width of the small table body. This structure ensures that the small table is subjected to balanced forces.

[0016] Preferably, the small table body has receiving grooves on both sides, and the first and second transmission rods pass through the receiving grooves. When the small table body is in the folded position, the first and second transmission rods are located within the receiving grooves. With the above structure, the small table can fit snugly against the back of the seat back when folded.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The electrically adjustable backrest table provided by this utility model has a drive mechanism arranged horizontally inside the table body, which does not occupy the internal space of the backrest and does not affect the arrangement of the internal modules of the seat backrest, thus ensuring the comfort of the ride.

[0019] 2. The small table has a tight internal transmission and a compact structure, which does not compress the rear space.

[0020] 3. The small table is driven by a lead screw, which can move horizontally and be suspended in any position to bear force, and can meet greater load-bearing capacity and abuse force. Attached Figure Description

[0026] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0027] like Figure 1 and Figure 3 As shown, an electrically adjustable backrest table includes a table body 1, a transmission assembly 3 connected to the table body 1, the transmission assembly 3 being used to allow the table body 1 to be flipped and mounted on the back of the seat, and a drive mechanism 2 integrated inside the table body 1, the drive mechanism 2 being used to drive the transmission assembly 3 to move, so that the table body 1 flips and switches between an unfolded position and a folded position.

[0028] like Figure 4 As shown, the drive mechanism 2 includes a slider 23 and a synchronizing rod 25. The synchronizing rod 25 is a square shaft, rotatably mounted inside the small table body 1 along its length. A sleeve 27 is fixedly fitted in the middle of the synchronizing rod 25, and a rocker arm 242 is provided on the sleeve 27 along its radial direction. A connecting rod 241 is hinged to the end of the rocker arm 242, and the other end of the connecting rod 241 is rotatably connected to the slider 23. The small table body 1 has a hollow mounting chamber 11 inside, and two sets of sliding grooves 111 parallel to the length direction of the lead screw are provided inside the hollow mounting chamber 11. The two ends of the slider 23 are reciprocally mounted in the sliding grooves 111. The small table body 1, slider 23, connecting rod 241, and rocker arm 242 constitute a four-bar linkage. To balance the force on the slider 23, there are two sets of rocker arms 242 and connecting rods 241, symmetrically arranged on both sides of the slider 23. A torsion spring 26 is fitted on the synchronizing rod 25. The two ends of the torsion spring 26 are supported on the rocker arm 242 and the small table body 1, respectively, which can make the drive mechanism run more stably and without shaking.

[0029] like Figure 4 As shown, the drive mechanism 2 also includes a power component for driving the slider 23 to reciprocate. In this embodiment, the power component includes a motor 21 fixed inside the small table body 1 and a lead screw 22 driven by the motor 21. The lead screw 22 is positioned in the middle of the synchronizing rod 25 along the width direction of the small table body 1. The slider 23 is threadedly connected to the lead screw 22 and moves along the length direction of the lead screw 22. Driven by the lead screw 22, it can not only be tightly installed inside the small table body 1, but also move horizontally, hovering and bearing force at any position, and can meet greater load-bearing capacity and abuse force.

[0030] like Figure 1 and Figure 4 As shown, the synchronizing rod 25 is connected to the transmission assembly 3. The transmission assembly 3 includes a mounting member 33 and a first transmission rod 31 and a second transmission rod 32 rotatably connected to both ends of the mounting member 33, as shown. Figure 2 As shown, the mounting component 33 is used to fix it to the back of the seat. There are two sets of first transmission rods 31 and second transmission rods 32, symmetrically arranged on both sides of the small table body 1 in the width direction. The end of the first transmission rod 31 away from the mounting component 33 is rotatably connected to the small table body 1, and the end of the second transmission rod 32 away from the mounting component 33 is fixedly connected to the synchronizing rod 25. The first transmission rod 31, the second transmission rod 32, the small table body 1, and the mounting component 33 constitute a four-bar linkage. The small table body 1 has receiving grooves 12 on both sides. The first transmission rod 31 and the second transmission rod 32 pass through the receiving grooves 12. When the small table body 1 is in the folded position, the first transmission rod 31 and the second transmission rod 32 are located within the receiving grooves 12.

[0031] like Figure 2 As shown, when the small table body 1 is in the folded position, it fits snugly against the seat back, avoiding compressing the rear passenger space. Figure 3 and Figure 4 As shown, when the small table body 1 is in the unfolded position, the motor 21 first drives the lead screw 22 to rotate. The slider 23 is threadedly engaged with the lead screw 22. Due to the restriction of the sliding grooves 111 at both ends, the slider 23 moves back and forth along the length of the lead screw 22. The two ends of the slider 23 are connected to the connecting rod 241 and the rocker arm 242, which transmits power to the synchronizing rod 25, driving the synchronizing rod 25 to rotate. Under the transmission action of the two sets of first connecting rods 31 and second transmission rods 32 connected to the two ends of the synchronizing rod 25, the small table body 1 unfolds relative to the seat back. Through a small and compact structural design, a large angle adjustment of the small table body 1 is achieved without significantly increasing the thickness of the small table body 1, thus integrating the drive mechanism 2 inside the small volume of the small table body 1.

[0032] like Figure 3As shown, in this embodiment, the drive mechanism 2 is arranged horizontally inside the small table body 1, and the thickness of the small table body 1 can be controlled within 45mm. The small table body 1 is connected to the back of the seat via the transmission assembly 3, without occupying the internal space of the backrest or affecting the arrangement of the internal modules of the seat back, thus ensuring the comfort of the passenger.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
