Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, and in particular to a rear-row armrest small table installation structure and an automobile seat. Background Art

[0002] Some models have an integrated armrest on the middle seat in the rear row, which can be flipped and stored in the middle backrest of the rear row. By folding the armrest on the middle backrest forward, it can provide arm support for the rear passengers. However, as passengers' requirements for comfort and convenience in the car increase, a single support function can no longer meet the needs of passengers.

[0003] In the prior art, a small table is additionally provided on the rear armrest. By rotating the small table horizontally, the small table can be placed in front of the passengers on both sides, making it convenient for the passengers to work, eat or place items in the car. Regarding the setting of the small table on the armrest, the current technical problem is that the small table is unfolded in a horizontal rotation manner. Since the position of the armrest is usually flush with the passenger's knees, the small table is easy to interfere with the passenger's knees during the unfolding process, thereby reducing the passenger's comfortable riding experience. Summary of the invention

[0004] In view of this, one of the purposes of the present invention is to provide a rear armrest small table mounting structure that can raise the unfolded use height of the small table to ensure the riding comfort of the passengers.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A rear-row armrest small table mounting structure includes an armrest assembly and a small table arranged on top of the armrest assembly, and is characterized in that a lifting mechanism is provided between the small table and the armrest assembly, and when the armrest small table is unfolded for use, the lifting mechanism can move the small table upward relative to the armrest assembly.

[0007] By adopting the above structure, the height of the small table can be raised through the provided lifting mechanism, thereby ensuring the riding comfort of the passengers.

[0008] Preferably, the lifting mechanism includes a lifting bracket, one end of which is rotatably connected to the front of the armrest assembly, and the small table is rotatably connected to the end of the lifting bracket away from the armrest assembly. The lifting bracket can be flipped upward from a horizontal position to a vertical position, and the small table can be rotated 90° forward or backward relative to the lifting bracket; when the armrest and small table are folded, the small table and the lifting bracket are both stored in a horizontal position on the armrest assembly. With the above structure, after the lifting bracket flips upward to lift the small table as a whole, the small table is rotated 90° forward or backward relative to the lifting bracket, which can ensure that the small table is in a horizontal state when in use, meeting the basic requirements of use.

[0009] As a preferred embodiment: the lifting bracket is rotatably mounted on the armrest assembly via a pin shaft, an adapter block is rotatably provided at one end of the lifting bracket away from the pin shaft, one end of the small table is rotatably mounted on the adapter block, and the small table can be flipped forward 90° relative to the adapter block; the rotation direction of the adapter block relative to the lifting bracket and the rotation direction of the lifting bracket relative to the armrest assembly are perpendicular to each other in space, and the rotation direction of the small table relative to the adapter block and the rotation direction of the lifting bracket relative to the armrest assembly are parallel in space. With the above structure, when the small table needs to be used, the lifting bracket is first flipped upward to a vertical posture, the small table is then flipped forward 90° relative to the adapter block, and finally the adapter block is rotated horizontally relative to the lifting bracket.

[0010] Preferably, when the armrest table is folded, the lower front side of the table has a mounting groove, the adapter block is hinged in the mounting groove, and after the table is flipped forward 90° relative to the adapter block, the table can be positioned and supported on the adapter block. With the above structure, by flipping the table forward, it can be ensured that the table has enough rotation space when the adapter block rotates horizontally.

[0011] Preferably, the lifting mechanism further comprises a driving device for driving the lifting bracket to automatically flip. With the above structure, the lifting and folding of the lifting bracket can be electrically controlled.

[0012] Preferably, the driving device comprises a first driving motor, the output end of the first driving motor is connected to an output gear, the lifting bracket has an arc-shaped tooth plate, and the arc-shaped tooth plate and the output gear are meshed with each other. With the above structure, the lifting bracket can be electrically controlled to rotate relative to the armrest assembly through the meshing transmission of the arc-shaped tooth plate and the output gear, thereby driving the lifting and folding of the small table.

[0013] Preferably, the lifting bracket is in an N-shaped structure, including two parallel rotating parts and a connecting part connecting the two rotating parts, the two ends of the pin shaft are hinged at one end of the two rotating parts away from the connecting part; the arc-shaped tooth plate is arranged at one end of one rotating part close to the pin shaft, and the adapter block is hinged at the middle position of the connecting part. With the above structure, the lifting bracket of the N-shaped structure can rotate more stably, thereby making the small table board more stably supported.

[0014] Preferably, a mounting plate is provided inside the armrest assembly, and both left and right ends of the mounting plate are folded upward to form folded parts, the pin is fixedly arranged between the two folded parts, and the first drive motor is fixedly arranged on one of the folded parts. The above structure can facilitate the installation of the first drive motor and the pin, and by arranging the mounting plate inside the armrest assembly, the overall structure can be made more compact.

[0015] Preferably, the rear ends of the folding parts are fixed with extension plates, and the ends of the two extension plates away from the folding parts are connected by a synchronization rod, one end of the synchronization rod protrudes outwards beyond the armrest assembly and is powered by a second drive motor. With the above structure, the armrest assembly can be electrically controlled to perform forward and backward flipping movements.

[0032] The present invention is further described below in conjunction with embodiments and drawings.

[0033] Embodiment 1:

[0034] like Figures 1 to 4 As shown, a rear armrest and small table installation structure includes an armrest assembly 1 and a small table 2 arranged on the top of the armrest assembly 1, and a lifting mechanism is arranged between the small table 2 and the armrest assembly 1. When the armrest and small table are unfolded for use, the lifting mechanism can move the small table 2 upward relative to the armrest assembly 1.

[0035] Through the design of the lifting mechanism, the unfolded use height of the small table 2 is raised, avoiding interference with the passenger's knees, thereby ensuring the passenger's riding comfort.

[0036] Specifically, the lifting mechanism includes a lifting bracket 3, one end of the lifting bracket 3 is rotatably connected to the front part of the armrest assembly 1, and the small table 2 is rotatably connected to the end of the lifting bracket 3 away from the armrest assembly. The lifting bracket 3 can be flipped upward from a horizontal posture to a vertical posture, and the small table 2 can also be rotated 90° forward or backward relative to the lifting bracket 3. When the armrest and small table are in the folded state, the small table 2 and the lifting bracket 3 are both placed on the armrest assembly 1 in a horizontal posture. With this design, after the lifting bracket 3 is flipped upward to lift the small table 2 upward as a whole, the small table 2 is rotated 90° forward or backward relative to the lifting bracket 3, which can ensure that the small table 2 is in a horizontal state when in use, meeting the basic requirements of use.

[0037] Furthermore, the lifting bracket 3 is rotatably mounted on the armrest assembly 1 through the pin shaft 4, and the adapter block 5 is rotatably mounted on the end of the lifting bracket 3 away from the pin shaft 4, one end of the small table 2 is rotatably mounted on the adapter block 5, and the small table 2 can be flipped forward 90° relative to the adapter block 5, and the rotation direction of the adapter block 5 relative to the lifting bracket 3 and the rotation direction of the lifting bracket 3 relative to the armrest assembly 1 are perpendicular to each other in space, and the rotation direction of the small table 2 relative to the adapter block 5 and the rotation direction of the lifting bracket 3 relative to the armrest assembly 1 are parallel in space.

[0038] Based on the above design, after flipping the lifting bracket 3 upward to a vertical position, the small table 2 is driven to flip forward 90° relative to the adapter block 5, and finally the adapter block 5 is driven to rotate left or right relative to the lifting bracket 3, so that the armrest small table can be convenient for passengers to use.

[0039] like Figures 2 to 4 As shown, when the armrest table is folded, the lower front side of the table 2 has a mounting groove 2a, and the adapter block 5 is hinged in the mounting groove 2a. After the table 2 is flipped forward 90° relative to the adapter block 5, the table 2 can be positioned and supported on the adapter block 5. By using the design that the table 2 is flipped forward 90° relative to the adapter block 5, when the lifting bracket 3 is flipped upward to a vertical posture, the table 2 can be extended forward as a whole, so that when the adapter block 5 rotates relative to the lifting bracket 3, the table 2 has enough rotation space and will not interfere with the occupants.

[0040] In this embodiment, the lifting mechanism also includes a driving device for driving the lifting bracket 3 to automatically flip. Figure 6 As shown, the driving device includes a first driving motor 6, an output gear 6a is fixedly mounted on the output end of the first driving motor 6, and an arc-shaped tooth plate 3c is formed on the lifting bracket 3, and the arc-shaped tooth plate 3c and the output gear 6a are meshed with each other. Through the meshing transmission between the output gear 6a and the arc-shaped tooth plate 3c, the flipping of the lifting bracket 3 is electrically controlled, thereby facilitating the upward unfolding of the small table 2.

[0041] Further, such as Figure 5 As shown, the lifting bracket 3 is an n-shaped structure, which includes two parallel rotating parts 3a and a connecting part 3b connecting the two rotating parts 3a, the two ends of the pin 4 are hinged at the ends of the two rotating parts 3a away from the connecting part 3b, the arc-shaped tooth plate 3c is formed at the end of one of the rotating parts 3a close to the pin 4, and the adapter block 5 is hinged at the middle position of the connecting part 3b. By configuring the lifting bracket 3 into an n-shaped structure, the lifting bracket 3 can be rotated more stably, and at the same time, it can also support the small table 2 more stably.

[0042] like Figure 6 As shown, a mounting plate 7 is fixedly installed inside the armrest assembly 1, and folded portions 7a are folded upward at both left and right ends of the mounting plate 7, a pin 4 is fixedly inserted between the two folded portions 7a, and a first drive motor 6 is fixedly installed on one of the folded portions 7a. With such a design, by arranging the first drive motor 6 and the pin 4 inside the armrest assembly 1, the overall structure of the armrest assembly 1 can be made more compact.

[0043] For example Figure 7As shown, a limit stop pin 10 is provided at the upper end of the folding portion 7a, and a baffle 3d is extended toward the corresponding folding portion 7a at one end of the two rotating portions 3a close to the pin shaft 4. The lifting bracket 3 is flipped forward, so that the baffle 3d can finally abut against the limit stop pin 7. With this design, the forward flip angle of the lifting bracket 3 can be limited.

[0044] Furthermore, a torsion spring 11 is mounted on the pin shaft 4, a limiting protrusion 4a is arranged in the middle of the pin shaft 4, an arc-shaped hole 7c is formed on the folding portion 7a, one end of the torsion spring 11 abuts against the limiting protrusion 4a, and the other end is penetrated in the arc-shaped hole 7c, and a locking hook 3e is arranged at one end of the rotating portion 3a close to the pin shaft 4. When the lifting bracket 3 flips backward, the locking hook 3e can contact the torsion spring 11 and push the torsion spring 11 to move in the arc-shaped hole 7c. Since the other end of the torsion spring 11 abuts against the limiting protrusion 4a, the torsion spring 11 cannot rotate with it, and then forms a lock with the locking hook 3e. With such a design, the angle of the lifting bracket 3 flipping backward can be limited.

[0045] In this embodiment, the locking hook 3e and the arc-shaped tooth plate 3c are respectively formed on a baffle 3d, so as to ensure that the overall structure is more compact.

[0046] like Figure 8 As shown, the rear ends of the folding parts 7a are fixedly connected with extension plates 7b, and the ends of the two extension plates 7b away from the folding parts 7a are connected by a synchronization rod 8. In this embodiment, one end of the synchronization rod 8 protrudes outwardly beyond the armrest assembly 1 and is powered by a second drive motor 9. With such a design, the rotation of the armrest assembly 1 can be electrically controlled, thereby facilitating the folding of the armrest.

[0047] like Fig. 9 As shown, a first receiving groove 1a adapted to the cross section of the lifting bracket 3 and a second receiving groove 1b adapted to the cross section of the adapter block 5 are formed on the top of the armrest assembly 1. When the lifting bracket 3 is flipped backward, it can eventually rotate and fold into the first receiving groove 1a, and the adapter block 5 can rotate with it and eventually fold into the second receiving groove 1b. With this design, the overall structure of the armrest assembly 1 can be more compact after the small table 2 is folded.

[0048] A storage slot 1c is also provided at the top front end of the armrest assembly 1, and the storage slot 1c is arranged in the area between the two rotating parts 3a. Such a design can ensure the original storage function of the armrest assembly 1.

[0049] like Figure 1 As shown, a headrest 12 is fixedly installed at the front bottom of the armrest assembly 1. The headrest 12 can support the head of the occupant when the armrest assembly 1 is rotated and folded backward.

[0050] Based on the above structure, during the actual use of the armrest table installation structure, the second drive motor 9 first drives the armrest assembly 1 to rotate to Figure 1 The first drive motor 6 then drives the lifting bracket 3 to flip forward to Figure 2 The small table 2 is then manually turned forward 90° relative to the adapter block 5 to achieve Figure 3 The effect shown is achieved by rotating the small table 2 horizontally. Figure 4 and Fig.10 The effect is shown.

[0051] The small table 2 can be electrically unfolded by the first drive motor 6 and the second drive motor 9. At the same time, the design of the lifting bracket 3 increases the usable height of the small table 2, so that when the small table 2 rotates horizontally, it will not interfere with the knees of the occupants, thereby ensuring the riding comfort of the occupants.

[0052] Embodiment 2:

[0053] like Fig.10 As shown, a car seat includes a backrest 13 and a rear armrest table mounting structure as described in the first embodiment, a third receiving groove 13a is provided on the front side of the backrest 13, and the armrest assembly 1 can be integrated in the third receiving groove 13a in a flipping manner through the control of the second drive motor 9. Such a design enables the armrest assembly 1 to be stored in the third receiving groove 13a when not in use, thereby making the overall structure of the car seat more compact.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
