[0040] Please also read Figures 1 to 6 The seat elbow pillow provided by the utility model is now described. The seat elbow pillow comprises: a receiving cavity, an elbow pillow body 3, a driving mechanism 4 and a swing arm connecting rod mechanism 2.

[0041] The accommodating cavity is arranged on the side of the seat 5, and can rely on the larger space inside the seat 5 frame to hide the driving mechanism 4 and the swing arm connecting rod mechanism 2 in the accommodating cavity without occupying the external space of the seat 5, so it has a reasonable layout and sufficient layout space; wherein, the accommodating cavity is arranged at a rotation position close to the backrest of the seat 5, and is located on the left or right side of the backrest of the seat 5; at the same time, in order to avoid interference with the installation position of the seat belt, the seat elbow pillow provided in the present application can be preferentially installed on the side of the backrest of the seat 5 where the seat belt buckle is not arranged.

[0042] The elbow pillow body 3 has a support surface for supporting the elbow, wherein the support surface has a certain length extending along the front-rear direction of the vehicle body so as to be able to support the forearm of the arm. The elbow pillow body 3 is driven by the drive motor 401 and the gear transmission group. Therefore, the swing arm connecting rod mechanism 2 can be stopped at a certain angle by the rotation of the drive motor 401, and the elbow pillow body 3 rises from the side of the seat 5, and the maximum rising position is when the support surface is in a horizontal state. Considering the design of the installation position of the gear transmission group, the design structure of the swing arm connecting rod mechanism 2, the swing arm length of the swing arm connecting rod mechanism 2, the design of the motion trajectory and other related factors, the elbow pillow body 3 rotates and rises from the side of the seat 5 to the front side of the backrest of the seat 5 when rising, and when stored, the support surface of the elbow pillow body 3 can be connected or flush with the seat cushion of the seat 5.

[0043] The driving mechanism 4 is hidden and installed in the accommodating cavity; the driving mechanism 4 includes a driving motor 401 and a gear transmission group connected to the main shaft of the driving motor 401; the present application utilizes the gear transmission group with a compact structure, stable and reliable force transmission and good self-locking performance, providing a power source and stable and reliable support for the movement of the elbow pillow body 3.

[0044] The swing arm link mechanism 2 is connected between the gear transmission group and the elbow pillow body 3, and drives the elbow pillow body 3 to rise or be stored to the side of the seat 5 through the rotation of the gear transmission group. The swing arm link mechanism 2 plans the movement trajectory of the elbow pillow body 3, and provides reliable support for the elbow pillow body 3 as a support function after the elbow pillow body 3 rises.

[0045] The seat elbow pillow provided by the utility model can be stored to the side of the seat 5 and will not occupy the lateral space of the seat 5. Therefore, it can be arranged on the side of the co-pilot seat 5 and the rear seat 5 to provide elbow support for the passengers in the car and meet the needs of the passengers in the car; Fig. 9 As shown, when the passenger needs elbow support, the electrically driven gear transmission group drives the elbow pillow body 3 to rotate counterclockwise and rise to a certain height through the swing arm connecting rod mechanism 2, which can provide support for the passenger's elbow. When the passenger is in a zero-gravity state with full body relaxation, it can provide additional support for the passenger's waist, so that the passenger's waist and arms can be effectively relaxed and rested, avoiding the problem of shoulder and waist pain caused by long-term riding, and improving the passenger's riding comfort; Figure 7 As shown, when the passenger does not need elbow support, the elbow pillow body 3 is driven by the swing arm linkage mechanism 2 to rotate clockwise and be stored on the side of the seat 5. The elbow pillow body 3 will not occupy the lateral space of the seat back 5, reducing the crowded feeling in the vehicle interior and improving the riding experience.

[0046] To explain, the lateral direction in the lateral space of the seat back 5 referred to here refers to the left-right direction of the vehicle body.

[0047] The installation position of the seat elbow pillow of this application is as follows Figures 7 to 10As shown, the examples are as follows: Example 1, installed on the right side of the front passenger seat 5, near the B-pillar of the vehicle body, before opening the door, the elbow pillow body 3 is driven by the driving motor 401 and the swing arm linkage mechanism 2 to be stored on the side of the seat back 5, or the side of the seat cushion of the seat 5, and is flush with the seat cushion of the seat 5, or slightly lower than the upper surface of the seat cushion, and will not interfere with the occupant getting off the vehicle; when the occupant gets on the vehicle and closes the door, the elbow pillow body 3 can be raised according to personal needs; Example 2, installed on the left and right sides of the rear seat 5 or between the rear seats 5.

[0048] It should be noted that an electric button for controlling the opening and closing of the drive motor 401 can be set on the seat 5 at a position that does not interfere with the sitting posture of the human body, so that the occupant can operate the elbow pillow body 3 according to personal preference; the electric button can also be set on the body near the left and right sides of the seat 5.

[0049] In some embodiments, Figures 3 to 6 As shown, the gear transmission group includes a driving gear 402, a driven gear 404, a first gear 405, a second gear 406, a third gear 407 and a fourth gear 408, the driving gear 402 is connected to the main shaft of the driving motor 401, the driven gear 404 is meshed with the driving gear 402, the driven gear 404, the first gear 405 and the second gear 406 are coaxially connected to the first shaft; the third gear 407 is connected to the second shaft 409, and the fourth gear 408 is loosely sleeved on the second shaft 409, so the fourth gear 408 has a different rotation speed from the third gear 407, the third gear 407 is meshed with the first gear 405, the fourth gear 408 is meshed with the second gear 406, and the first gear 405, the second gear 406, the third gear 407 and the fourth gear 408 constitute a differential transmission structure; wherein the second shaft 409 is parallel to the first shaft, and the second shaft 409 and the first shaft are both connected to the accommodating cavity. The gear transmission group has two transmission routes. In route one, the driving gear 402 drives the driven gear 404 to rotate, and the driven gear 404 drives the first shaft to rotate, thereby driving the first gear 405 and the second gear 406 to rotate, and the first gear 405 drives the third gear 407 to rotate, thereby driving the short arm rod 21 to swing; in route two, the driving gear 402 drives the driven gear 404 to rotate, and the driven gear 404 drives the first shaft to rotate, thereby driving the first gear 405 and the second gear 406 to rotate, and the second gear 406 drives the fourth gear 408 to rotate, thereby driving the long arm rod 23 to swing, and two different rotation speeds are obtained through a driving motor 401.

[0050] like Figure 1 and Figure 2As shown, the swing arm connecting rod mechanism 2 includes a long arm rod 23, a short arm rod 21 and a connecting rod 22; one end of the long arm rod 23 is fixed on the fourth gear 408, and the other end is hinged on the elbow pillow body 3; one end of the short arm rod 21 is fixed on the second shaft 409, and the other end is hinged on the connecting rod 22, and the two ends of the connecting rod 22 are respectively hinged on the short arm rod 21 and the elbow pillow body 3, the rotation speed of the long arm rod 23 is less than the rotation speed of the short arm rod 21, and the long arm rod 23 and the short arm rod 21 rotate differentially through the differential transmission structure; the long arm rod 23 is an integral structure, and the long arm rod 23 is driven to rotate at a low speed through the fourth gear 408, providing high power support for the elbow pillow body 3; the short arm rod 21 is hinged to the connecting rod 22, and the short arm rod 21 obtains a fast rotation speed through the third gear 407, and changes the transmission direction through the hinged connecting rod 22, thereby adjusting the movement trajectory of the elbow pillow body 3. Therefore, driven by the driving motor 401, the long arm lever 23 and the short arm lever 21 start to rotate at the same time at different rotation speeds, driving the elbow pillow body 3 to rise along a certain trajectory.

[0051] The long arm 23 and the short arm 21 rotate differentially through a differential transmission structure, and have a certain speed ratio, which is as follows:

[0052] Defined as follows: the number of teeth of the first gear 405 is n1, the number of teeth of the second gear 406 is n2, the number of teeth of the third gear 407 is n3, and the number of teeth of the fourth gear 408 is n4. Then, the ratio of the rotation speed of the long arm 23 to the rotation speed of the short arm 21 is i=(n2×n3)÷(n1×n4). Specifically, according to the installation position of the driving mechanism 4, the length of the transmission chain of the gear transmission group, the structural design and length selection of the long arm 23, the short arm 21 and the connecting rod 22, the ratio of the rotation speed of the long arm 23 to the rotation speed of the short arm 21 is i=1:3, or i=0.345, that is, the rotation speed ratio is preferably between 0.3 and 0.5.

[0053] Among them, the length of the long arm is greater than the length of the short arm.

[0054] In some embodiments, Figure 3 As shown, the gear transmission group further includes an intermediate transmission gear 403, which is meshed between the driving gear 402 and the driven gear 404. Since the space on the side of the seat 5 is relatively narrow, the drive motor 401 will occupy a certain space, and the intermediate transmission gear 403 is used to increase the transmission chain, so that the drive motor 401 can be arranged inside the seat 5, thereby ensuring the installation space of the drive mechanism 4 and the swing arm connecting rod mechanism 2.

[0055] In some embodiments, Figure 3As shown, the intermediate transmission gear 403, the driving gear 402 and the driven gear 404 have the same number of teeth. The intermediate transmission gear 403 is an intermediate force transmission component. By matching the same number of teeth, the rotation speed of the driving gear 402 is stable and the same rotation speed is transmitted to the driven gear 404, and then to the first gear 405 and the second gear 406. For example, the number of teeth of the driving gear 402 is 35, 30 or 40, etc.

[0056] In some embodiments, Figure 3 As shown, the number of teeth n1 of the first gear 405 is greater than the number of teeth n3 of the third gear 407, the number of teeth n2 of the second gear 406 is the same as the number of teeth n3 of the third gear 407, and the number of teeth n4 of the fourth gear 408 is the same as the number of teeth n1 of the first gear 405. In the selection of the number of teeth of the gears, the ratio of the number of teeth of the third gear 407 to that of the fourth gear 408 is kept at 1:1.7, and the ratio of the number of teeth of the first gear 405 to that of the second gear 406 is kept at 1.7:1. For example, n1=46, n2=27, n3=46, n4=27, then i=0.345; n1=40, n2=24, n3=40, n4=24, then i=0.36; n1=42, n2=24, n3=42, n4=24, then i=0.33.

[0057] In some embodiments, Figure 1 and Figure 2 As shown, the hinge point between the connecting rod 22 and the elbow pillow body 3 is located above the hinge point between the long arm rod 23 and the elbow pillow body 3. The long arm rod 23 is an integral component, with a hinge point at the bottom and a slow rotation speed, providing large torque support for the elbow pillow body 3; the short arm rod 21 and the connecting rod 22 form a component, with a fast rotation speed, capable of changing direction, and providing guidance for the rotation direction of the elbow pillow body 3.

[0058] In some embodiments, Figure 1 and Figure 2 As shown, a protective shell 1 is provided in the accommodating cavity, the second shaft 409 is penetrated in the protective shell 1, and the long arm rod 23 and the connecting rod 22 are partially located in the protective shell 1; the elbow pillow body 3 includes an elbow pillow shell 31, and the long arm rod 23 and the connecting rod 22 are partially located in the elbow pillow shell 31. When the elbow pillow body 3 is stored to the side of the seat 5, the elbow pillow shell 31 is connected to the protective shell 1, and the long arm rod 23 and the connecting rod 22 can be hidden in the elbow pillow shell 31 and the protective shell 1. Among them, except for the second shaft 409, the other components of the driving mechanism 4 are located outside the protective shell 1 and hidden in the space inside the seat 5. The protective shell 1 is on the side of the seat 5 and is an appearance part, which has a protective effect on the swing arm connecting rod mechanism 2. The elbow pillow body 3 is also an appearance part, and the elbow pillow shell 31 also has a protective effect on the swing arm connecting rod mechanism 2, and needs to have a smooth outer surface to avoid scratches and injuries to the occupants.

[0059] Furthermore, if Figure 1 and Figure 2 As shown, the elbow pillow body 3 also includes a protective pad 33 arranged on the elbow pillow shell 31. The protective pad 33 can be wrapped with leather material and directly contact the occupant's elbow to improve the comfort of elbow support.

[0060] Furthermore, the elbow rest housing 31 comprises an exterior housing and an exterior housing cover clamped on the exterior housing, wherein a long hole for the long arm rod 23 and the connecting rod 22 to swing is provided on the exterior housing.

The protective housing 1 swings with the long arm rod 23 to provide real-time protection for the long arm rod 23, and since the rotation speed of the connecting rod 22 is different from that of the long arm rod 23, the protective housing 1 also needs to be provided with an avoidance hole 13 (such as Figure 4 As shown), this can also reduce the opening length of the avoidance hole 13 and improve the visibility of the appearance.

[0063] The cover plate 12 and the decorative shell 11 are connected by clamping or bolting, wherein a clamping claw 121 is provided on the cover plate 12 , and a clamping hole 111 for clamping the clamping claw 121 is provided on the decorative shell 11 .

[0064] In some embodiments, Figure 6 As shown, the long arm lever 23 has a second through hole through which the second shaft 409 passes, and a radially extending synchronous block 231 is arranged in the second through hole, and the axially extending first sleeve of the fourth gear 408 has an axial keyway 4081 meshing with the synchronous block 231; the short arm lever 21 has an axially extending second sleeve, which is sleeved on the second shaft 409 and fixed by bolts. The fourth gear 408 drives the long arm lever 23 to rotate synchronously by meshing with the long arm lever 23; the short arm lever 21 is directly fastened to the second shaft 409 and rotates synchronously with the third gear 407.
