[0030] The following refers to Figures 1-4 Describe the seat 100 according to an embodiment of the present utility model. By connecting the headrest 2 to the headrest rod 3, the headrest 2 is supported by the headrest rod 3, and the headrest 2 can move driven by the headrest rod 3, that is, the height of the headrest 2 is adjusted to meet the needs of occupants of different heights. In addition, by connecting the headrest rod 3 to the adjustment mechanism 4, the headrest rod 3 can drive the headrest rod 3 to rise and fall under the action of the adjustment mechanism 4, realizing the automatic adjustment of the height of the headrest 2, which can improve the convenience of use, and the headrest rod 3 can move forward when rising to provide a more comfortable riding experience for the occupants, which is beneficial to improving user satisfaction.

[0031] As Figures 1-4 As shown, the seat 100 according to an embodiment of the present utility model includes: a seat backrest 1, a headrest 2, a headrest rod 3, and an adjustment mechanism 4.

[0032] Among them, the seat backrest 1 and the headrest 2 can be used to support the back and head of the occupant respectively, so as to relieve the fatigue of the occupant caused by long-time riding, reduce the impact on the back and neck of the occupant when the vehicle collides, protect the occupant, and provide a more comfortable riding experience for the occupant. The headrest rod 3 is used to support and fix the headrest 2 to ensure that the headrest 2 can be firmly fixed on the seat 100. Connecting the headrest 2 to the headrest rod 3 can realize the installation of the headrest 2 on the vehicle through the headrest rod 3, and enable the headrest 2 to move relative to the seat backrest 1 driven by the headrest rod 3 to adjust the height of the headrest 2 to meet the needs of occupants of different heights. At the same time, setting the headrest rod 3 above the seat 100 and connecting the headrest 2 to the upper end of the headrest rod 3 can set the headrest 2 at the top of the seat 100 to facilitate the support and protection of the occupant's head by the headrest 2.

[0033] In addition, it should be noted that the headrest 2 and the headrest rod 3 can be an integrated mechanism, that is, the headrest 2 and the headrest rod 3 can be fixedly connected so that there is no relative movement between them, thereby improving the reliability of the movement of the headrest 2 driven by the headrest rod 3.

[0034] The adjustment mechanism 4 is installed in the seat backrest 1. The adjustment mechanism 4 includes a driving member 41, a transmission member 42 and a headrest rod holder 43. The lower end of the headrest rod 3 is connected to the headrest rod holder 43. The driving member 41 is connected to the transmission member 42. The transmission member 42 is in threaded cooperation with the headrest rod holder 43. The driving member 41 is adapted to drive the transmission member 42 to rotate so that the headrest rod holder 43 drives the headrest rod 3 to move up and down. The headrest rod 3 is arranged to move up and down in an arc track, and the upper part of the headrest rod 3 is arranged to move forward when rising.

[0035] Specifically, the adjusting mechanism 4 is used to adjust the height of the headrest 2. By arranging the adjusting mechanism 4 inside the seat backrest 1, the installation of the adjusting mechanism 4 can be achieved, and the exposure of the adjusting mechanism 4 can be avoided, preventing it from easily colliding with other components on the vehicle and causing damage and failure. At the same time, the adjusting mechanism 4 includes a driving member 41, a transmission member 42, and a headrest rod holder 43. The driving member 41 is used to provide driving force for the movement of the headrest 2. Connecting the driving member 41 to the transmission member 42 enables the transmission member 42 to rotate under the action of the driving member 41 and transmit the driving force provided by the driving member 41. Connecting the transmission member 42 to the headrest rod holder 43 allows the transmission member 42 to transmit the driving force provided by the driving member 41 to the headrest rod holder 43. Moreover, connecting the headrest rod holder 43 to the headrest rod 3 enables the transmission member 42 to transmit the driving force provided by the driving member 41 from the driving member 41 through the headrest rod holder 43 to the headrest rod 3, so that the driving member 41 can drive the transmission member 42 to rotate, causing the headrest rod holder 43 to drive the headrest rod 3 to move up and down. Consequently, the headrest 2 can move up and down under the action of the driving member 41, achieving automatic adjustment of the height of the headrest 2 to adapt to occupants of different heights. Additionally, the maximum stroke of the movement of the headrest rod 3 can be controlled through the movement of the headrest rod holder 43 to prevent the headrest rod 3 from moving too far and falling off the seat 100 or interfering with other components inside the seat 100 and causing damage.

[0036] Furthermore, the headrest rod 3 moves in an arc trajectory, allowing the headrest rod 3 to move forward or backward while rising or falling, that is, it can approach or move away from the user's head while moving up and down. The upper part of the headrest rod 3 is set to move forward when rising, enabling the headrest rod 3 to approach the user's head while rising, which conforms to ergonomics and provides a more comfortable riding experience for the occupant, facilitating the improvement of user satisfaction.

[0037] Among them, it should be noted that as Figures 2-3 shown, connecting the lower end of the headrest rod 3 to the headrest rod holder 43 can connect the headrest 2 and the headrest rod holder 43 to the two ends of the headrest rod 3 respectively, spacing them apart to avoid interference between them and preventing the adjustment of the height of the headrest 2. At the same time, a threaded fit between the transmission member 42 and the headrest rod holder 43 can be achieved, enabling the transmission member 42 to form an external thread and the headrest rod holder 43 to form an internal thread, or vice versa, to realize the connection between the transmission member 42 and the headrest rod holder 43 through the cooperation between the external thread and the internal thread. The connection method is simple and reliable. In addition, the driving member 41 can be configured as an electric motor.

[0038] Thus, by providing the seat back 1 and the headrest 2 on the seat 100, the occupant can be protected. The headrest 2 is connected to the headrest rod 3, so that the headrest 2 can move relative to the seat back 1 driven by the headrest rod 3. Moreover, by providing an adjustment mechanism 4 inside the seat back 1, the driving member 41 can drive the transmission member 42 to rotate, so that the headrest rod holder 43 drives the headrest rod 3 to move up and down, and the headrest rod 3 moves forward when rising, so that the headrest 2 can approach the occupant's head.

[0039] For the seat 100 according to the embodiment of the present invention, by providing the seat back 1 and the headrest 2 on the seat 100, the occupant can be protected. At the same time, by connecting the headrest 2 to the headrest rod 3, the headrest 2 can be supported by the headrest rod 3, and the headrest 2 can move driven by the headrest rod 3, that is, the height of the headrest 2 is adjusted to meet the needs of occupants of different heights. Moreover, by connecting the headrest rod 3 to the adjustment mechanism 4, the headrest rod 3 can drive the headrest rod 3 to move up and down under the action of the adjustment mechanism 4, realizing the automatic adjustment of the height of the headrest 2, which can improve the use convenience. And the headrest rod 3 can move forward when rising, providing a more comfortable riding experience for the occupant, which is beneficial to improving user satisfaction.

[0040] In some embodiments, the seat back 1 is provided with an arc-shaped guiding structure 11, and the headrest rod 3 is passed through the arc-shaped guiding structure 11 and is adapted to move up and down along the arc-shaped guiding structure 11.

[0041] Specifically, the arc-shaped guiding structure 11 is used to guide the movement of the headrest 2. By providing the arc-shaped guiding structure 11 on the seat back 1, the installation and fixation of the arc-shaped guiding structure 11 can be realized. At the same time, by passing the headrest rod 3 through the arc-shaped guiding structure 11, the connection between the headrest rod 3 and the arc-shaped guiding structure 11 can be realized, so as to improve the reliability of guiding the movement of the headrest rod 3 by the arc-shaped guiding structure 11. Moreover, the headrest rod 3 is used to drive the headrest 2 to move, so that the headrest rod 3 can move up and down along the arc-shaped guiding structure 11, that is, the headrest 2 can move up and down along the arc-shaped guiding structure 11 driven by the headrest rod 3, thereby improving the accuracy and reliability of the movement direction of the headrest 2.

[0042] In some embodiments, the arc-shaped guiding structure 11 forms an arc-shaped guiding cavity 111, the headrest rod 3 is configured as an arc-shaped rod, and the headrest rod 3 is passed through the arc-shaped guiding cavity 111 and moves up and down along the arc-shaped guiding cavity 111 in an arc-shaped trajectory.

[0043] Specifically, the arc-shaped guiding structure 11 is used to guide the movement of the headrest 2 through the headrest rod 3. The headrest rod 3 is passed through the arc-shaped guiding structure 11 so that the headrest rod 3 can be lifted and lowered along the arc-shaped guiding structure 11. And the arc-shaped guiding structure 11 is formed with an arc-shaped guiding cavity 111. That is, the headrest rod 3 can be passed through the arc-shaped guiding cavity 111 to realize the connection between the headrest rod 3 and the arc-shaped guiding structure 11. Furthermore, the reliability of the headrest rod 3 being lifted and lowered along the arc-shaped guiding structure 11 can be improved. At the same time, the arc-shaped guiding cavity 111 extends in an arc shape, so that the movement trajectory of the headrest rod 3 in the arc-shaped guiding cavity 111 is also arc-shaped. And the headrest rod 3 is configured as an arc-shaped rod, so that the headrest rod 3 can adapt to the shape of the arc-shaped guiding cavity 111. Furthermore, the headrest rod 3 can be lifted and lowered along the arc-shaped guiding cavity 111 in an arc-shaped trajectory in the arc-shaped guiding cavity 111, so that the headrest 2 can be lifted and lowered in an arc-shaped trajectory under the drive of the headrest rod 3, providing a more comfortable riding experience for the occupant.

[0044] In some embodiments, the headrest rod 3 is configured to bend and extend forward from bottom to top.

[0045] Specifically, the arc-shaped guiding cavity 111 extends in an arc shape, and the headrest rod 3 is configured as an arc-shaped rod, so that the headrest 2 can be lifted and lowered in an arc-shaped trajectory along the arc-shaped guiding cavity 111 under the drive of the headrest rod 3. The headrest rod 3 is configured to bend and extend forward from bottom to top, so that the headrest 2 will move forward while moving upward, approaching the occupant's head, which conforms to ergonomics and provides a more comfortable riding experience for the occupant. And the headrest rod 3 can provide a forward supporting force for the headrest 2, improving the reliability of supporting the headrest 2 through the headrest rod 3. On the contrary, when the headrest 2 moves downward, it will move backward and move away from the occupant to achieve reset, which can reduce space occupancy and is beneficial to improving user satisfaction.

[0046] In some embodiments, both the headrest rod 3 and the arc-shaped guiding structure 11 are multiple, and the multiple arc-shaped guiding structures 11 are cooperatively matched with the multiple headrest rods 3 one by one.

[0047] Specifically, the headrest rod 3 is used to support the headrest 2. Multiple headrest rods 3 can be provided on the seat 100 at the same time, that is, the number of headrest rods 3 provided can be two, three or more. Furthermore, the headrest 2 can be supported by multiple headrest rods 3 together to improve the reliability of supporting the headrest 2. And multiple headrest rods 3 can be arranged at intervals to support the headrest 2 from multiple positions at the same time, improving the stability of supporting the headrest 2. At the same time, the arc-shaped guiding structure 11 is used to guide the movement of the headrest rod 3. Multiple arc-shaped guiding structures 11 can be provided on the seat 100 at the same time, and the number of arc-shaped guiding structures 11 provided is the same as the number of headrest rods 3 provided, and multiple arc-shaped guiding structures 11 are matched with multiple headrest rods 3 one by one. That is, for each headrest rod 3, an arc-shaped guiding structure 11 is provided to guide it, which can improve the reliability of guiding the movement of the headrest rod 3 through the arc-shaped guiding structure 11, and further improve the accuracy of the movement direction of the headrest 2.

[0048] In some embodiments, the seat 100 further includes a connecting bracket 5. The seat backrest 1 includes a backrest frame 12. The connecting bracket 5 is relatively fixed to the backrest frame 12. The driving member 41 is connected to the connecting bracket 5 through a flexible connecting member 6.

[0049] Specifically, the connecting bracket 5 is used to install and fix the adjusting mechanism 4. The seat backrest 1 includes a backrest frame 12. The connecting bracket 5 is relatively fixed to the backrest frame 12. That is, the connecting bracket 5 can be connected to the backrest frame 12 to realize the installation of the connecting bracket 5. At the same time, by connecting the driving member 41 to the connecting bracket 5, the connection between the driving member 41 and the backrest frame 12 can be realized through the connecting bracket 5, that is, the installation and fixation of the driving member 41 are realized, improving the reliability of the driving member 41 working. And the driving member 41 is connected to the connecting bracket 5 through a flexible connecting member 6. Because the flexible connecting member 6 has a certain elastic force, the driving member 41 can realize the linkage swing in the front and back directions when the headrest 2 moves up and down. Furthermore, the driving member 41 can adapt to the movement track of the lower end of the headrest rod 3, ensuring that the headrest rod 3 can move up and down along an arc-shaped track.

[0050] In the embodiment as Figure 3 shown, a fixing bracket 7 is further provided between the backrest frame 12 and the connecting bracket 5. The backrest frame 12 and the connecting bracket 5 are respectively connected to the fixing bracket 7 to realize the connection between the backrest frame 12 and the connecting bracket 5. Among them, the backrest frame 12 can be connected to the fixing bracket 7 by welding, and the connecting bracket 5 can extend to the front side of the fixing bracket 7 and be attached to the fixing bracket 7. And the fixing bracket 7 can be connected to the connecting bracket 5 by threaded connection to realize the relative fixation between the backrest frame 12 and the connecting bracket 5.

[0051] Also, it should be noted that in this application, the flexible connecting member 6 is used to achieve the synchronous swinging of the driving member 41. In actual design, the synchronous swinging of the driving member 41 can also be achieved by using a chute mechanism.

[0052] In some embodiments, the flexible connecting member 6 includes a first clamping portion 61 and a second clamping portion 62. The first clamping portion 61 is used for clamping connection with the driving member 41, and the second clamping portion 62 is used for clamping connection with the connecting bracket 5.

[0053] Specifically, the flexible connecting member 6 is used to connect the driving member 41 and the connecting bracket 5. That is, the driving member 41 and the connecting bracket 5 can be respectively connected to the flexible connecting member 6, so that the flexible connecting member 6 includes a first clamping portion 61 and a second clamping portion 62. The first clamping portion 61 is used for clamping connection with the driving member 41, that is, the connection between the flexible connecting member 6 and the driving member 41 can be achieved through the first clamping portion 61. The second clamping portion 62 is used for clamping connection with the connecting bracket 5, that is, the connection between the flexible connecting member 6 and the connecting bracket 5 can be achieved through the second clamping portion 62. And the clamping connection method is simple and reliable, and can reduce the number of connecting parts used and lower the setting cost.

[0054] Exemplarily, as Figure 3 shown, the flexible connecting member 6 is configured as an I-shaped. A first clamping portion 61 is formed below the flexible connecting member 6, and a first clamping groove 63 is formed on the driving member 41. The clamping connection between the flexible connecting member 6 and the driving member 41 can be achieved through the cooperation between the first clamping portion 61 and the first clamping groove 63. A second clamping portion 62 is formed above the flexible connecting member 6, and a second clamping groove 64 is formed on the connecting bracket 5, so that the second clamping portion 62 can penetrate through the second clamping groove 64 and be in clamping cooperation with the second clamping groove 64, and the clamping connection between the flexible connecting member 6 and the connecting bracket 5 can be achieved, thereby the connection between the driving member 41 and the connecting bracket 5 can be achieved.

[0055] Also, it should be noted that, as Figure 3 shown, two first clamping portions 61 are spaced apart on the flexible connecting member 6. That is, the connection between the flexible connecting member 6 and the driving member 41 can be achieved through the two first clamping portions 61, which can improve the connection reliability and connection stability between the two. At the same time, two second clamping portions 62 are spaced apart on the flexible connecting member 6. That is, the connection between the flexible connecting member 6 and the connecting bracket 5 can be achieved through the two second clamping portions 62, which can improve the connection reliability and connection stability between the two.

[0056] In some embodiments, the transmission member 42 is configured as a transmission lead screw. The driving member 41 is connected to the transmission lead screw. The headrest rod holder 43 is provided with a threaded hole 431, and the transmission lead screw passes through the threaded hole 431 and is in threaded cooperation with the headrest rod holder 43.

[0057] Specifically, as Figures 2-4 shown, the transmission member 42 is used to transmit the driving force provided by the driving member 41. By constructing the transmission member 42 as a transmission lead screw, the driving force of the driving member 41 can be transmitted through the transmission lead screw. Moreover, by connecting the transmission lead screw to the driving member 41, the reliability of the transmission of the driving force of the driving member 41 by the transmission lead screw can be improved. At the same time, by arranging the transmission lead screw vertically along the vehicle and providing a threaded hole 431 on the headrest rod holder 43, the transmission lead screw can be passed through the threaded hole 431 and threadedly engaged with the headrest rod holder 43, so that the connection between the transmission lead screw and the headrest rod holder 43 can be achieved through the threaded engagement method. Furthermore, the headrest rod holder 43 can be lifted and lowered under the action of the transmission lead screw, that is, the headrest rod holder 43 can drive the headrest rod 3 to lift and lower, and thus the height of the headrest 2 can be adjusted.

[0058] Among them, it should be noted that the driving member 41 can be arranged horizontally or vertically along the vehicle in the seat back 1. When the driving member 41 is arranged vertically along the vehicle, the transmission lead screw can be directly connected to the output shaft of the driving member 41. When the driving member 41 is arranged horizontally along the vehicle, the transmission lead screw can be connected to the output shaft of the driving member 41 through a gear structure, so that the headrest rod holder 43 can drive the headrest rod 3 to lift and lower. In this application, the driving member 41 is arranged at the upper end of the transmission member 42. In actual design, the driving member 41 can also be arranged at the lower end of the transmission member 42, which can be flexibly set according to specific situations and space sizes.

[0059] In addition, it should be noted that a lead screw holder 8 is also arranged in the seat back 1. The lead screw holder 8 is sleeved outside the transmission lead screw and is used to support the transmission lead screw to improve the reliability of the operation of the transmission lead screw. The lead screw holder 8 can be connected to the driving member 41 by a clamping method to realize the installation and fixation of the lead screw holder 8, and further improve the reliability of supporting the transmission lead screw by the lead screw holder 8.

[0060] In some embodiments, there are multiple headrest rods 3, and the lower end of each headrest rod 3 is clamped and connected to the headrest rod holder 43.

[0061] Specifically, the headrest rod 3 is used to support the headrest 2 and drive the headrest 2 to move to adjust the height of the headrest 2. By setting the headrest rods 3 in multiple numbers, the headrest 2 can be supported by multiple headrest rods 3 together, which can improve the reliability of supporting the headrest 2. Moreover, the headrest 2 can be driven to rise and fall by multiple headrest rods 3 together, which can improve the reliability of the headrest 2 rising and falling driven by the headrest rods 3. At the same time, each headrest rod 3 is connected to the headrest rod holder 43, so that the headrest rod holder 43 can drive multiple headrest rods 3 to move simultaneously. In addition, the lower end of each headrest rod 3 is connected to the headrest rod holder 43, so that the headrest rod holder 43 can drive the headrest rod 3 to move under the headrest rod 3, and the headrest 2 and the headrest rod holder 43 can be spaced apart at both ends of the headrest rod 3 to avoid interference between the two, resulting in the inability to adjust the height of the headrest 2.

[0062] In addition, the headrest rod 3 and the headrest rod holder 43 are connected by snap connection. That is, the headrest rod 3 can form a snap, and the headrest rod holder 43 can form a slot, or the headrest rod 3 can form a slot, and the headrest rod holder 43 can form a snap, so as to realize the connection between the headrest rod 3 and the headrest rod holder 43 through the cooperation between the snap and the slot, and the headrest rod holder 43 can drive the headrest rod 3 to rise and fall.

[0063] Alternatively, there are two headrest rods 3, and the lower end of each headrest rod 3 is connected to the headrest rod holder 43 by snap connection, and the transmission lead screw is located between the two headrest rods 3.

[0064] Specifically, as Figures 2-3 shown, the number of the headrest rods 3 can be set to two. The headrest 2 can be supported by two headrest rods 3 together and driven to rise and fall, so as to improve the reliability of supporting the headrest 2 and the reliability of driving the headrest 2 to rise and fall. Both of the two headrest rods 3 are connected to the headrest rod holder 43, so that the headrest rod holder 43 can drive the two headrest rods 3 to move simultaneously. In addition, the lower ends of the two headrest rods 3 are connected to the headrest rod holder 43, so that the headrest rod holder 43 can drive the headrest rods 3 to move under the headrest rods 3, and the headrest 2 and the headrest rod holder 43 can be spaced apart at both ends of the headrest rods 3 to avoid interference between the two, resulting in the inability to adjust the height of the headrest 2.

[0065] Moreover, the headrest rod 3 is connected to the headrest rod holder 43 in a snap-fit manner, so that the connection between the two can be realized through the snap-fit connection, and the connection method is simple and reliable. The transmission lead screw can be arranged between the two headrest rods 3, that is, the driving force of the driving member 41 can be transmitted to the two headrest rods 3 on both sides at the same time, the forces on both sides of the transmission lead screw can be balanced, and then the headrest 2 can be lifted and lowered smoothly. And the transmission lead screw is relatively close to the two headrest rods 3, so as to improve the transmission efficiency of the driving force, and further improve the efficiency of adjusting the height of the headrest 2, which is beneficial to improving the user satisfaction.

[0066] In addition, it should be noted that the movement stroke of the headrest 2 in this application can reach 160 mm, effectively increasing the adjustment range of the height of the headrest 2, and further increasing the applicable range of the seat 100.

[0067] The present utility model also proposes a vehicle.

[0068] The vehicle according to the embodiment of the present utility model is provided with the seat 100 in any one of the above. By providing the seat back 1 and the headrest 2 on the seat 100, the occupants can be protected. At the same time, by connecting the headrest 2 to the headrest rod 3, the headrest 2 can be supported by the headrest rod 3, and the headrest 2 can move under the drive of the headrest rod 3, that is, the height of the headrest 2 is adjusted to meet the needs of occupants of different heights. Moreover, by connecting the headrest rod 3 to the adjustment mechanism 4, the headrest rod 3 can drive the headrest rod 3 to rise and fall under the action of the adjustment mechanism 4, realizing the automatic adjustment of the height of the headrest 2, which can improve the use convenience, and the headrest rod 3 can move forward when rising, providing a more comfortable riding experience for the occupants, which is beneficial to improving the user satisfaction.
