DETAILED DESCRIPTION

[0055] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0056] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0057] Figure 1 is a schematic diagram of a three-dimensional structure of an automobile door panel armrest assembly from one viewing angle according to an embodiment of the present invention; Figure 2 FIG. 2 is a schematic diagram of a three-dimensional structure of an automobile door panel armrest assembly according to another perspective of an embodiment of the present invention. Figure 1 and Figure 2 As shown, the automobile door panel armrest assembly according to the embodiment of the present invention mainly includes: a fixing portion 1 , a connecting portion 2 and an armrest portion 3 .

[0058] The fixing portion 1 is fixed to the inside of the vehicle door. Here, the inside of the vehicle door refers to the cavity inside the vehicle door formed by the door interior panel 4 and the door outer shell 5. It is understandable that in order to hide the armrest portion 3 when the user does not need to use it, the fixing portion 1 can be fixed to any position inside the vehicle door, such as the side of the door interior panel 4 facing the inside of the vehicle door, or on the door panel sheet metal inside the vehicle door. The fixing portion 1 can be fixed to the inside of the vehicle door by screwing or clamping, etc., which is not specifically limited here.

[0059] The two ends of the connecting portion 2 are movably connected to the fixing portion 1 and the armrest portion 3, respectively. In order to maintain the connection stability between the fixing portion 1 and the armrest portion 3, a plurality of connecting portions 2 may be provided. One end of the connecting portion 2 is movably connected to the fixing portion 1, and the other end is movably connected to the armrest portion 3. When the user needs to adjust the position of the armrest portion 3, the position of the armrest portion 3 can be adjusted by relative displacement between the connecting portion 2 and the fixing portion 1 or between the connecting portion 2 and the armrest portion 3.

[0060] like Figure 3 , Figure 4 and Figure 5 As shown, under the drive of external force, the armrest portion 3 can switch between a hidden state and an extended state. When the armrest portion 3 is in the hidden state, the armrest portion 3 is hidden inside the door; when the armrest portion 3 is in the extended state, the armrest portion 3 is extended from the door.

[0061] It should be noted that the door interior panel 4 is provided with a notch 41 through which the armrest 3 can pass. When the user does not need to use the armrest 3, the armrest 3 can be switched from the extended state to the hidden state, the armrest 3 is retracted into the vehicle door through the notch 41 on the door interior panel 4, and the armrest 3 is locked in the hidden state, so that the user cannot see the automobile door panel armrest assembly from the vehicle cabin, thereby expanding the user's activity space in the vehicle cabin; when the user needs to use the armrest 3, the armrest 3 can be switched from the hidden state to the extended state, the armrest 3 is extended from the vehicle door through the notch 41 on the door interior panel 4, and the armrest 3 is locked in the extended state, so that the user can lean on it.

[0062] Optionally, a shielding curtain may be provided above the notch 41 , and when the armrest portion 3 is in a hidden state, the shielding curtain falls down under the action of gravity and covers the notch 41 , so as to improve the aesthetics of the interior of the vehicle.

[0063] In an optional embodiment, if Figure 6 As shown, the connecting portion 2 comprises a first embedded end 21 connected to the fixing portion 1, a second embedded end 22 connected to the armrest portion 3, and a connecting rod 23. The connecting rod 23 is located between the first embedded end 21 and the second embedded end 22.

[0064] Accordingly, if Figure 7 As shown, the fixing part 1 is provided with a first groove 11. One side of the fixing part 1 is fixed inside the vehicle door, and the other side is provided with the first groove 11. The first embedding end 21 is embedded in the first groove 11 to realize the movable connection between the connecting part 2 and the fixing part 1. Figure 8 As shown, a second groove 31 is provided on one side of the armrest portion 3 close to the fixing portion 1 , and the second embedding end 22 is embedded in the second groove 31 to realize the movable connection between the connecting portion 2 and the armrest portion 3 .

[0065] Furthermore, if Fig. 9 and Fig.10 As shown, the first embedded end 21 may include a first embedded component 211 and a first connecting component 212. The first embedded end 21 may be in a T-shaped structure, wherein a width W1 of the first embedded component 211 is greater than a width W2 of the first connecting component 212.

[0066] The first groove 11 in the fixing portion 1 extends along the length direction of the vehicle body. The shape of the first groove 11 corresponds to the shape of the first embedded end 21, and is in a T-shaped structure to accommodate the first embedded end 21. The first embedded member 211 is embedded in the first groove 11; the first connecting member 212 connects the first embedded member 211 and the connecting rod 23. The opening width W3 of the first groove 11 is smaller than the width W1 of the first embedded member 211, so that the first embedded member 211 will not fall out of the first groove 11 after being embedded in the first groove 11.

[0067] Furthermore, if Fig.11 , Fig.12 and Fig.13 As shown, the bottom length L1 of the first groove 11 is greater than the length L2 of the first insert 211, so that the first groove 11 can accommodate multiple first inserts 211 and leave enough space for the first insert 211 to move forward and backward in the first groove 11. The number of first grooves 11 can be only one, and the number of first inserts 211 embedded in the first groove 11 can be multiple, and should be the same as the number of connecting rods 23.

[0068] like Fig.10 As shown, the first embedded part 211 is provided with a first rack 2111 on one side corresponding to the bottom of the first groove 11. Fig.13 As shown, a first transmission chain 111 meshing with the first rack 2111 is disposed at the bottom of the first groove 11. After the first insert 211 is engaged with the first groove 11, the first rack 2111 meshes with the first transmission chain 111. Driven by an external force, the first transmission chain 111 rotates in the length direction of the vehicle body, so that the first rack 2111 drives the first insert 211 to move in the length direction of the vehicle body, and then the connecting portion 2 drives the armrest portion 3 to move forward and backward relative to the vehicle door, thereby satisfying the user's need to move the armrest portion 3 forward or backward.

[0069] As an example, when the first transmission chain 111 moves forward relative to the vehicle door, it drives the first rack 2111 to move forward, so that the connecting part 2 drives the armrest part 3 to move forward, thereby satisfying the user's demand for the armrest part 3 to move forward; when the first transmission chain 111 moves backward relative to the vehicle door, it drives the first rack 2111 to move backward, so that the connecting part 2 drives the armrest part 3 to move backward, thereby satisfying the user's demand for the armrest part 3 to move backward.

[0070] Furthermore, if Figure 6 As shown, the second embedded end 22 includes a second embedded component 221 and a second connecting component 222. Similar to the first embedded end 21, the second embedded end 22 may also be in a T-shaped structure.

[0071] The second groove 31 of the armrest portion 3 extends along the width direction of the vehicle body. The shape of the second groove 31 corresponds to the shape of the second embedded end 22, and is a T-shaped structure to accommodate the second embedded end 22. The second embedded member 221 is embedded in the second groove 31; the second connecting member 222 connects the second embedded member 221 and the connecting rod 23. The opening width of the second groove 31 is smaller than the width of the second embedded member 221, so that the second embedded member 221 will not fall out of the second groove 31 after being embedded in the second groove 31.

[0072] The bottom length L3 of the second groove 31 is greater than the length L4 of the second insert 221, thereby leaving enough space for the second insert 221 to move left and right in the second groove 31. The number of the second grooves 31 should be the same as the number of the second inserts 221, and each second groove 31 is correspondingly provided with a second insert 221.

[0073] The second insert 221 is provided with a second rack on one side corresponding to the bottom of the second groove 31. Figure 8 As shown, a second transmission chain 311 meshing with the second rack is disposed at the bottom of the second groove 31. Driven by an external force, the second transmission chain 311 rotates in the width direction of the vehicle body, so that the second rack drives the second insert 221 to move in the width direction of the vehicle body, and then the connecting portion 2 drives the armrest portion 3 to move to the left and right relative to the vehicle door, thereby meeting the user's demand for the armrest portion 3 to move to the left or right, and at the same time, the extension amount of the armrest portion 3 from the notch 41 can also be adjusted.

[0074] As an example, when the second transmission chain 311 moves to the left relative to the vehicle door, it drives the second rack to move to the left, so that the armrest portion 3 moves to the left, thereby satisfying the user's demand for the armrest portion 3 to move to the left or to reduce the extension amount of the armrest portion 3; when the second transmission chain 311 moves to the right relative to the vehicle door, it drives the second rack to move to the right, so that the armrest portion 3 moves to the right, thereby satisfying the user's demand for the armrest portion 3 to move to the right or to increase the extension amount of the armrest portion 3.

[0075] In an optional embodiment, if Figure 6 As shown, the first embedded end 21 and the connecting rod 23 may be connected via a rotating shaft 24. Driven by an external force, the rotating shaft 24 rotates, so that the connecting rod 23 drives the armrest portion 3 to switch between the hidden state and the extended state.

[0076] When the user needs to use the armrest part 3, the rotating shaft 24 can be driven by external force to rotate, so that the armrest part 3 in the hidden state can be extended from the inside of the door through the slot 41 and switched to the extended state for the user to lean on; when the user no longer needs to use the armrest part 3, the rotating shaft 24 can be driven by external force to rotate, so that the armrest part 3 in the extended state can be retracted into the inside of the door through the slot 41 and switched to the hidden state, so as to provide the user with a more spacious space for activities in the cabin.

[0077] In an optional embodiment, the armrest portion 3 includes an outer layer 32 and an inner layer 33, wherein the outer layer 32 wraps the inner layer 33. The outer layer 32 and the inner layer 33 cooperate to provide the user with a comfortable sense of support. The pattern, fabric, and appearance of the outer layer 32 can be customized according to the user's preferences. The outer layer 32 can be made of elastic materials, including but not limited to polyvinyl chloride, polyurethane, etc.

[0078] Optionally, in the thickness direction, the content layer 33 includes a foaming layer 331, an airbag layer 332 and a skeleton layer 333 stacked in sequence. The airbag layer 332 may be a folded airbag having different heights when the gas volume inside the airbag is different. The skeleton layer 333 may be made of a hard material to support the structure of the armrest portion 3. For example, the foaming layer 331 may be made of a polyurethane foam material, a 3D spacer fabric, or the like.

[0079] The foaming layer 331 is provided to increase the comfort of the armrest 3 when in use and enhance the sense of support. The airbag layer 332 is provided to adjust the volume of gas inside the airbag and thus adjust the height of the armrest 3.

[0080] Furthermore, the automobile door panel armrest assembly of the embodiment of the present invention may further include: an inflation and deflation device. The inflation and deflation device may be arranged at any position in the vehicle cabin or inside the vehicle door, and connected to the airbag layer 332 through a pipeline, and is used to inflate and deflate the airbag layer 332, adjust the volume of gas in the airbag layer 332, and further adjust the height of the armrest portion 3, so as to meet the height requirements of the armrest portion 3 for users of different body shapes and postures.

[0081] In an optional embodiment, the automobile door panel armrest assembly may further include: a control unit. The control unit is used to receive a control signal and generate a driving force for driving the armrest portion 3 and the connecting portion 2 based on the control signal, so that the armrest portion 3 moves relative to the vehicle door in any one or more of the following directions: height direction, front, rear, top and bottom.

[0082] The control unit is connected to the vehicle computer and receives control signals from the vehicle computer. It is understandable that the control signals may include control signals for the first transmission chain 111, the second transmission chain 311, the inflating device, the rotating shaft 24, etc., so that the armrest 3 is driven to move forward or backward by controlling the rotation of the first transmission chain 111 in the length direction of the vehicle body, the armrest 3 is driven to move left or backward by controlling the rotation of the second transmission chain 311 in the width direction of the vehicle body, the airbag layer 332 is inflated or deflated by controlling the inflating and deflation device, the gas volume in the airbag layer 332 is adjusted to adjust the height of the armrest 3, and the rotation of the rotating shaft 24 is controlled to switch the armrest 3 between the hidden state and the extended state.

[0083] The control signal can be triggered by the user through the vehicle computer, or it can be automatically triggered by the vehicle computer under a preset scenario. When the control signal is triggered by the user through the vehicle computer, the user triggers the control signal through the vehicle computer to adjust the armrest 3 to a position that meets their own needs; when the control signal is automatically triggered by the vehicle computer, the armrest 3 can be automatically hidden and extended based on the current scene of the vehicle. As an example, when the driver uses automatic driving, the control signal of the automatic hiding of the armrest 3 is triggered to provide the driver with a more spacious space for activities in the cabin; when the driver manually takes over the driving operation of the vehicle, the control signal of the automatic extension of the armrest 3 is triggered to facilitate the driver to lean on it; when the vehicle computer recognizes that the current vehicle has collided, the control signal of the automatic hiding of the armrest 3 is triggered to prevent the extended armrest 3 from causing secondary damage to the user. By automatically triggering the control signal in different scenarios, the flexibility and utilization rate of the armrest 3 are improved.

[0084] It should be noted that Figure 1 , Figure 2 , Figure 3 and Fig.11 Only two connecting parts 2 are shown as examples. In the embodiment of the present invention, the number of connecting parts 2 can be 2 or more, and the actual number can be set according to actual conditions. Fig.12 Only one first transmission chain 111 is shown as an example. In actual situations, the number of first transmission chains 111 can be the same as the number of first inserts 211, so that each first insert 211 corresponds to a first transmission chain 111. Driven by external force, all first transmission chains 111 move in the same direction at the same speed, driving each first insert 211 to move, and then driving the armrest portion 3 to move in the length direction of the vehicle body through the connecting portion 2, even if the armrest portion 3 moves in the front and rear directions relative to the door.

[0085] The automobile door panel armrest assembly of the embodiment of the present invention is configured such that the armrest portion 3 can be switched between a hidden state and an extended state by fixing the fixing portion 1 inside the door and connecting the fixing portion 1 and the armrest portion 3 through the connecting portion 2. When the user needs to lean on the armrest, the armrest portion 3 can be extended from the inside of the door and switched from the hidden state to the extended state for the user to use; when the user does not need to lean on the armrest, the armrest portion 3 can be retracted into the door and switched from the extended state to the hidden state, thereby expanding the user's activity space in the vehicle.

[0086] The structure of the automobile door panel armrest assembly in the embodiment of the present invention can realize the adjustment of the armrest part 3 in the height direction, front-to-back direction and left-to-right direction, and can meet the personalized needs of users with different body shapes and postures for the armrest.

[0087] In addition, the automobile door panel armrest assembly of the embodiment of the present invention decouples the armrest from the automobile door, making the armrest assembly independent. Only the fixing part 1 needs to be fixed inside the door, which is convenient for the installation, maintenance and replacement of the armrest assembly, and the armrest assembly can be customized and personalized according to user needs.

[0088] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may occur depending on design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
