DETAILED DESCRIPTION

[0043] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0044] Please see attached Figure 1 To Attachment Figure 3 , an armrest structure assembly in a vehicle, comprising: an armrest 1, wherein a storage cavity 101 is formed in the armrest 1; a cover plate 2 disposed on the armrest 1; a conversion assembly connecting the armrest 1 and the cover plate 2, wherein the conversion assembly is configured to: 1) enable the cover plate 2 to flip relative to the armrest 1 between a closed position covering the storage cavity 101 and an open position using the storage cavity 101, as shown in the attached Figure 1 2) and the cover plate 2 can be raised and lowered between a closed position and a raised position relative to the armrest 1 to serve as a table top, as shown in the attached Figure 2 shown.

[0045] The armrest 1 is any seat armrest structure with a storage cavity 101 in a car, preferably a large armrest in the middle of a rear seat. When the cover plate 2 covers the storage cavity 101, it can serve as a top cover of the storage cavity 101, which is convenient for receiving and storing items. Figure 1 Preferably, the end of the cover plate 2 close to the seat back is connected to the shaft 201, so that the cover plate 2 can be turned around the shaft 201 to open, as shown in the attached Figure 1 As shown, it is convenient to put in and take out the items in the storage cavity 101; the end of the rotating shaft 201 can be locked with the cover plate 2 by a nut to prevent the rotating shaft from falling out of the cover plate 2.

[0046] The conversion assembly is used to lift the cover plate 2 to move it above the armrest 1, so that the cover plate 2 can also be used as a small table. The cover plate 2 is used to meet the use requirements of both the storage cover plate and the small table. The armrest with the storage cavity 101 is relatively wide, so that the available area of ​​the small table is large, and there is no need to install the small table on the rear console or the front table and chair frame. It has a wide range of applications and is not affected by the movement of the front seats. At the same time, the cover plate 2 is stably moved from the closed position to the raised position of the table plate by lifting and translating, as shown in the attached figure. Figure 2 As shown, it can not only meet the height requirement of the table top, but also avoid the occupation of the rear space of the car due to horizontal rotation.

[0047] Please see attached Figure 4 To Attachment Figure 7 , Attachment Fig. 9 To Attachment Fig.11 The conversion assembly includes a pair of connecting rods 301 and at least one supporting rod 302. The upper ends of the pair of connecting rods 301 are rotatably connected to the cover plate 2 through the rotating shaft 201, and the lower ends of the pair of connecting rods 301 are rotatably connected to the armrest 1; the upper end of at least one supporting rod 302 is movably clamped on the cover plate 2 through a clamping mechanism, and the lower end of at least one supporting rod 302 is rotatably connected to the armrest 1.

[0048] Preferably, a pair of connecting rods 301 and at least one supporting rod 302 in the conversion assembly can be installed in the gap between the armrest frame and the armrest shell, thereby providing movement space for the pair of connecting rods 301 and at least one supporting rod 302, and stopping at least one supporting rod 302 through the armrest shell when the armrest 1 is in the raised position, thereby facilitating the hidden installation of the connecting rods 301 and the supporting rods 302, without affecting the storage function of the storage cavity 101 in the armrest 1, and the structural design is more compact and beautiful.

[0049] The cover plate 2 can be rotated and lifted by rotating the connecting rod 301 and the supporting rod 302, and stable support can be provided for the cover plate 2, so that the cover plate 2 can always be kept in a horizontal state, and has good structural stability and load-bearing capacity, so that it can be used as a small table. The conversion component can control the movement of the connecting rod 301 and the supporting rod 302 manually, electrically, or the like.

[0050] Preferably, a sub-table plate 202 can be provided on the cover plate 2, and the sub-table plate 202 is flipably connected to the cover plate 2 through a connecting member 203 such as a hinge, a hinged joint, a rotating shaft, etc. When the sub-table plate 202 is covered on the cover plate 2, it is used as a cover plate of the storage cavity 101. When the sub-table plate 202 is opened, it is located in the same plane as the cover plate 2, thereby expanding the available area of ​​the table plate. Fig. 9 and attached Fig.10 The auxiliary table plate 202 is turned over to the left and right sides of the armrest 1 to facilitate the use of passengers sitting on the car seat.

[0051] Please see attached Figure 6 The clamping mechanism includes a clamping groove 303 and a fixing pin 304 matched with the clamping groove 303; the clamping groove 303 is arranged at the bottom of the cover plate 2, and the fixing pin 304 is connected with the pin hole at the upper end of the support rod 302. When the cover plate 2 moves between the closed position and the raised position, the fixing pin 304 and the clamping groove 303 remain clamped, so that at least one support rod 302 provides support for the cover plate 2; and when the cover plate 2 flips between the closed position and the open position, the fixing pin 304 and the clamping groove 303 remain disengaged.

[0052] Preferably, the snap-fitting groove 303 is a cylindrical groove with an opening, and the diameter of the cylindrical groove matches the diameter of the fixing pin 304, so that the fixing pin 304 can be inserted into the snap-fitting groove 303 through the opening through interference fit under the action of external force and can rotate relative to the snap-fitting groove 303, thereby adapting to the change in the connection angle between the cover plate 2 and the support rod 302 during the movement of the cover plate 2.

[0053] The opening width of the cylindrical groove can be slightly smaller than the diameter of the fixing pin 304 to prevent the fixing pin 304 from falling out of the snap-fit ​​groove 303 during the movement of the cover 2, and when the cover 2 is opened by external force, the fixing pin 304 can fall out of the snap-fit ​​groove 303, taking into account the flipping and opening functions and the lifting and translation functions of the cover 2.

[0054] Please see attached Figure 4 The conversion assembly includes a pair of connecting rods 301 and a pair of supporting rods 302. The pair of connecting rods 301 and the pair of supporting rods 302 are arranged at intervals, so as to be connected with the handrail 1 and the cover plate 2 to form a four-link structure.

[0055] Preferably, the symmetrically arranged pair of connecting rods 301 and the pair of supporting rods 302 can stably and horizontally support the cover plate 2, ensuring that the cover plate 2 remains stable and horizontal during movement. The four-link structure is linked under manual or electric external force drive to achieve the change of the height and horizontal position of the cover plate 2 to meet the dual function of the cover plate and the table top.

[0056] Please see attached Figure 7 , Attachment Figure 8 , Attachment Fig.14 and attached Fig.16 The armrest 1 includes an armrest frame, on which a reinforcing plate 102 is provided, and an axle pin 305 passes through at least one of the reinforcing plate 102 and the armrest frame to improve the strength of a pair of connecting rods 301 and at least one supporting rod 302.

[0057] Preferably, the reinforcing plate 102 can be arranged on the armrest frame to improve the Y-direction structural strength of the armrest frame and prevent the armrest frame from being deformed, cracked or damaged when the cover plate 2 is compressed; at the same time, the reinforcing plate 102 provides support for the support rod 302 and the connecting rod 301 in the Z direction. The reinforcing plate 102 can be located in the installation area of ​​the support rod 302 and the connecting rod 301, or it can be not installed in the installation area of ​​the support rod 302 and the connecting rod 301.

[0058] The reinforcing plate 102 may preferably be made of sheet metal, and the material of the reinforcing plate 102 may also be adaptively selected according to actual strength requirements.

[0059] Please see attached Fig.14 and attached Fig.15The reinforcing plate 102 is provided with a convex bump 103 that cooperates with the connecting rod 301 or the supporting rod 302. The convex bump 103 is configured to allow the connecting rod 301 or the supporting rod 302 to pass over the convex bump 103 during the lifting process of the cover plate 2, and to resist the connecting rod 301 or the supporting rod 302 when the cover plate 2 is in the lifted position, so that the cover plate 2 remains in the lifted position.

[0060] Preferably, the protrusion height of the convex bump 103 can be adaptively adjusted according to the gap between the connecting rod 301 or the supporting rod 302 and the reinforcing plate 102, so as to form a certain resistance to the rotation of the connecting rod 301 or the supporting rod 302 without blocking the rotation of the connecting rod 301 and the supporting rod 302. When the connecting rod 301 and the supporting rod 302 rotate under the action of an external force driven manually or electrically, they can squeeze and pass over the convex bump 103. The convex bump 103 is used to prevent the cover plate 2 from moving in the opposite direction and closing due to external factors such as shaking during the opening process of the cover plate 2. The number and arrangement position of the convex bump 103 can also be adaptively adjusted according to actual use requirements.

[0061] Preferably, the connecting rod 301 and the supporting rod 302 can be driven to rotate manually or electrically according to actual use requirements.

[0062] In manual drive mode: See attached Figure 4 , Attachment Figure 7 and attached Figure 8 The lower ends of a pair of connecting rods 301 are rotatably connected to the handrail 1 through an axle pin 305; the lower ends of at least one support rod 302 or a pair of support rods 302 are rotatably connected to the handrail 1 through an axle pin 305.

[0063] Preferably, the shaft pin 305 can be riveted to the reinforcing plate 12 to facilitate flexible and stable rotation of the shaft pin 305 .

[0064] When the cover plate 2 is in the closed state, the connecting rod 301 and the support rod 302 tilt backward. Manually push the cover plate 2 forward, and by utilizing the linkage of the four-bar structure, the cover plate 2 drives the connecting rod 301 and the support rod 302 to move forward synchronously, so that the connecting rod 301 rotates around its axle pin 305, and the support rod 302 rotates around its axle pin 305, so that the other end of the connecting rod 301 and the other end of the support rod 302 rotate upward and then downward along the circumference, so that the cover plate 2 is lifted to a certain height above the armrest 1. In this process, the other end of the connecting rod 301 and the other end of the support rod 302 are always at the same height, ensuring that the cover plate 2 is in a horizontal state and moves forward to the lifting position that also serves as a table top during the lifting process, meeting the use function of the table top and improving the use comfort of the table top. At this time, the connecting rod 301 and the support rod 302 tilt forward.

[0065] In electric drive mode: See attached Figure 7 and attached Figure 8A bushing 307 is sleeved on the shaft pin 305 to facilitate the rotation of the connecting rod 301 and the supporting rod 302 and improve the stability during the rotation process.

[0066] Please see attached Fig.12 To Attachment Fig.16 The conversion assembly also includes a motor 308 connected to one of the connecting rod 301 and the support rod 302; the other of the connecting rod 301 and the support rod 302 is rotatably connected to the handrail 1 through an axle pin 305; a spline 310 is provided on the driving shaft of the motor 308, and a spline groove connected to the spline 310 is provided on the connecting rod 301 or the support rod 302, so that the motor 308 drives the connecting rod 301 or the support rod 302 to rotate.

[0067] Preferably, one end of the spline 310 is coaxially fixed to the drive shaft of the motor 308, and the other end of the spline 310 is connected to the connecting rod 301 or the support rod 302 through a spline groove, so that the drive shaft of the motor 308 can drive the connecting rod 301 or the support rod 302 to rotate synchronously through the spline 310, thereby ensuring the stability of the transmission; the nut can be installed on the other end of the spline 310 through a gasket and abut against the connecting rod 301 or the support rod 302 to prevent the connecting rod 301 from being separated from the drive shaft of the motor 308 during rotation.

[0068] When the driving shaft of the motor 308 drives the connecting rod 301 to rotate via the spline 310, the four-bar linkage structure is used to rotate the connecting rod 301 while pushing the cover plate 2 to move upward and forward, and the cover plate 2 drives the other end of the support rod 302 to move synchronously, so that one end of the support rod 302 rotates synchronously with the connecting rod 301 around the shaft pin 305, thereby lifting and translating the cover plate 2 to a lifting position that also serves as a table top. Preferably, the motor 308 can be a small motor with a bidirectional rotation function in the prior art, and the forward and reverse functions of the motor can be used to realize the opening and closing of the cover plate 2.

[0069] Similarly, when the driving shaft of the motor 308 drives the support rod 302 to rotate via the spline 310, the linkage of the four-bar structure can be used to link the connecting rod 301 to rotate and lift and translate the cover plate 2 to a lifted position that also serves as a table top, which will not be repeated here.

[0070] Please see attached Fig.14 The electrically driven shaft pin 305 is also sleeved with a bushing 307 to facilitate the rotation of the connecting rod 301 or the supporting rod 302 and improve the stability during the rotation process.

[0071] Please see attached Figure 1 To Attachment Fig.11 , the use method and working principle of the utility model are (manual type):

[0072] Flip open the cover 2: hold the end of the cover 2 away from the shaft 201 and apply force upward and backward to flip the cover 2 backward around the shaft 201 to open the storage cavity 101. At this time, the snap-in slot 303 flips synchronously with the cover 2 and disengages from the fixing pin 304.

[0073] Flip and close the cover plate 2: When the cover plate 2 is flipped forward, the storage cavity 101 can be covered and closed, and the armrest 1 is used as an armrest of the car seat. At this time, the engaging groove 303 is flipped synchronously with the cover plate 2 and engaged with the fixing pin 304.

[0074] The cover plate 2 is used as a table top: manually push the end of the cover plate 2 connected to the rotating shaft 201 forward horizontally, and the cover plate 2 drives the connecting rod 301 and the supporting rod 302 to rotate forward. During the rotation process, the connecting rod 301 and the supporting rod 302 lift the cover plate 2 from the closed position to a certain height and move forward a certain distance to the lifting position that also serves as a table top, so that the cover plate 2 can be used as a table top. The auxiliary table top 202 can be opened to expand the available area of ​​the cover plate 2, and at this time, the storage cavity 101 can also be used.

[0075] Please see attached Figure 1 To Attachment Figure 3 , Attachment Fig.12 To Attachment Fig.16 Taking the motor 308 driving the connecting rod 301 as an example, the use method and working principle of the utility model are (electric type):

[0076] Flip open the cover 2: hold the end of the cover 2 away from the shaft 201 and apply force upward and backward to flip the cover 2 backward around the shaft 201 to open the storage cavity 101. At this time, the snap-in slot 303 flips synchronously with the cover 2 and disengages from the fixing pin 304.

[0077] Flip and close the cover plate 2: When the cover plate 2 is flipped forward, the storage cavity 101 can be covered and closed, and the armrest 1 is used as an armrest of the car seat. At this time, the engaging groove 303 is flipped synchronously with the cover plate 2 and engaged with the fixing pin 304.

[0078] The cover plate 2 is used as a table top: the motor 308 is started, and the driving shaft of the motor 308 drives the connecting rod 301 to rotate through the spline 310, and the connecting rod 301 drives the cover plate 2 to move upward and forward synchronously, and the cover plate 2 drives the support rod 302 to rotate synchronously with the connecting rod 301, so that the cover plate 2 is lifted and translated from the closed position to the lifted position that also serves as a table top. The auxiliary table plate 202 can be opened to expand the available area of ​​the cover plate 2, and at this time, the storage cavity 101 can also be used.
