[0046] This application provides a handrail assembly 100, which will be described in detail below with reference to the accompanying drawings.

[0047] Referring to Figures 1 to 4, a structural schematic diagram of a handrail assembly 100 provided in an embodiment of this application is shown. Referring to Figure 5, a partial enlarged view of position A in Figure 4 is shown. Referring to Figure 6, a structural schematic diagram of a lifting device 3 provided in an embodiment of this application is shown. Referring to Figure 7, a structural schematic diagram of a first support 31 provided in an embodiment of this application is shown. Referring to Figures 8 and 9, a structural schematic diagram of a display screen device 2 provided in an embodiment of this application is shown. Referring to Figures 10 and 11, structural schematic diagrams of the handrail 1 in a first position and a second position provided in an embodiment of this application are shown respectively.

[0048] As shown in Figures 1 to 5 and Figures 10 to 11, this application provides a handrail assembly 100, including: a handrail 1, a display screen device 2, and a lifting device 3; the handrail 1 is connected to the lifting device 3, which drives the handrail 1 to switch between a first position and a second position, the second position being higher than the first position; the display screen device 2 includes a display screen 21 and a flipping mechanism 22, the display screen 21 being movably connected to the handrail 1 through the flipping mechanism 22, which drives the display screen 21 to switch between an unfolded state and a retracted state. In the unfolded state, the display screen 21 can be unfolded relative to the handrail 1; in the retracted state, the display screen 21 can be retracted into the interior or side of the handrail 1.

[0049] In this embodiment, a lifting device 3 and a flipping mechanism 22 are provided. The lifting device 3 can drive the armrest 1 to switch between a first position and a second position, and the flipping mechanism 22 can drive the display screen 21 to switch between an unfolded state and a retracted state. Thus, when the armrest 1 and display screen 21 are needed, the lifting device 3 can first raise the armrest 1 from the first position to the second position, and then the flipping mechanism 22 can switch the display screen 21 to the unfolded state, so that the display screen 21 is unfolded relative to the armrest 1, thereby meeting the user's needs and improving the comfort and entertainment of the seat. When the armrest 1 and display screen 21 are not needed, the flipping mechanism 22 can first switch the display screen 21 to the retracted state, so that the display screen 21 is retracted into the interior or side of the armrest 1, and then the lifting device 3 can lower the armrest 1 from the second position to the first position, thereby increasing the seat space and improving the user experience.

[0050] It should be noted that the second position in this embodiment can be a fixed position, i.e., the height difference between the first position and the second position is fixed; or it can be a variable position, i.e., the height difference between the first position and the second position is adjustable. This is not limited here, and those skilled in the art can adjust it according to actual needs. It is understood that the second position can be variable by controlling the lifting height of the lifting device 3, thereby allowing the handrail assembly 100 to adapt to users of different heights, which is beneficial to improving the versatility of the handrail assembly 100.

[0051] Furthermore, when the lifting device 3 is in the first position, the armrest 1 is flush with the surface 61 of the seat body. In this way, when the armrest 1 is lowered to the first position, the top surface of the armrest 1 can remain flush with the surface 61 of the seat body, thereby improving the user's riding comfort.

[0052] Generally, the width of the display screen 21 is greater than the width of the armrest 1, which increases the size of the display screen 21 and improves the user's viewing comfort. Based on this, in one embodiment, the display screen 21 can be located on the front side of the armrest 1 (i.e., the side of the armrest 1 away from the seat back). In this way, in the unfolded state, the display screen 21 can be unfolded relative to the armrest 1, so that at least part of the display screen 21 protrudes from the inner side of the armrest 1 for user use; in the retracted state, the display screen 21 is retracted into the space in front of the armrest 1, so that the display screen 21 is flush with the inner side of the armrest 1 or maintains a certain distance from the inner side of the armrest 1, so as to prevent the display screen 21 from interfering with the seat body 6 during the descent of the armrest 1.

[0053] In some optional embodiments of this application, as shown in Figures 8 and 9, the flipping mechanism 22 includes a guide rail assembly 224 and a first drive assembly 223. The guide rail assembly 224 connects the display screen 21 and the first drive assembly 223. The first drive assembly 223 is configured to drive the guide rail assembly 224 to switch the display screen 21 between an unfolded state and a retracted state. Thus, by connecting the guide rail assembly 224 to the display screen 21 and the first drive assembly 223, under the driving action of the first drive assembly 223, the guide rail assembly 224 can drive the display screen 21 to flip, thereby achieving the switching between the unfolded and retracted states.

[0054] In this embodiment, the guide rail assembly 224 includes: a guide rail 221 and a guide block 222; a display screen 21 is connected to the guide block 222; the guide rail 221 is fixedly connected to the armrest 1, and the guide rail 221 includes a third position and a fourth position; the guide block 222 is slidably connected to the guide rail 221; when the guide block 222 slides to the third position, the display screen 21 is in a retracted state; when the guide block 222 slides to the fourth position, the display screen 21 is in an unfolded state; a first drive assembly 223 is connected to the guide block 222, and the first drive assembly 223 is used to drive the guide block 222 to slide relative to the guide rail 221. The first drive assembly 223 is fixedly connected to the armrest 1.

[0055] Furthermore, the guide rail 221 includes a guide rail body 2214 and a first guide groove 2211 and a second guide groove 2212 disposed on the guide rail body 2214, the first guide groove 2211 and the second guide groove 2212 being connected; a third position is located in the first guide groove 2211 and a fourth position is located in the second guide groove 2212.

[0056] In this embodiment, on one hand, since a guide rail 221 and a guide block 222 are provided, and the guide rail 221 includes a third position and a fourth position, wherein the third position is located in the first guide groove 2211 and the fourth position is located in the second guide groove 2212, the guide block 222 can switch between the third and fourth positions during the sliding process relative to the guide grooves (including the first guide groove 2211 and the second guide groove 2212), thereby driving the display screen 21 to flip, and thus achieving the switching between the unfolded state and the retracted state. On the other hand, since a first driving component 223 is provided and the first driving component 223 is connected to the guide block 222, the guide block 222 can be driven to slide relative to the guide rail 221, thereby driving the display screen 21 to flip.

[0057] Furthermore, the handrail 1 includes a handrail body 11 and a handrail support 12. The handrail body 11 is fixedly connected to the handrail support 12, and the handrail support 12 is fixedly connected to the lifting device 3. The guide rail 221 and the first drive assembly 223 of the tilting mechanism 22 are both fixedly connected to the handrail support 12. In addition, as shown in Figure 2, the handrail body 11 also includes a support member 111 and a handrail glove 112. The support member 111 is connected to the handrail support 12, and the handrail glove 112 is disposed on the side of the support member 111 facing away from the handrail support 12 and at least covers the support member 111, thereby providing comfortable and reliable support for the user. The support member 111 can be made of foam and / or plastic, and the handrail glove 112 can be made of foam.

[0058] In some optional embodiments of this application, as shown in FIG9, the display screen 21 includes: a display screen body 211 and a display screen bracket 212; the display screen body 211 is fixedly connected to the display screen bracket 212; the display screen bracket 212 is rotatably connected to the guide rail 221, and the display screen bracket 212 has a sliding groove 2121, with a guide block 222 slidably connected to the sliding groove 2121. That is, the guide block 222 is slidably connected to both the guide rail 221 and the display screen bracket 212. Thus, under the driving action of the first driving component 223, the guide block 222 moves and rotates relative to the guide rail 221 on the one hand, and moves relative to the display screen bracket 212 on the other hand, thereby causing the display screen bracket 212 to rotate relative to the guide rail 221, thereby realizing the flipping of the display screen 21.

[0059] Furthermore, if the extension direction of the guide rail 221 is the first direction, at least a portion of the display screen bracket 212 is fitted onto the guide rail 221, allowing the display screen bracket 212 to rotate relative to the guide rail 221 around the first direction, thereby causing the display screen body 211 to flip. In addition, the first guide groove 2211, the second guide groove 2212, and the slide groove 2121 all extend along the first direction to prevent the display screen bracket 212 from moving in any direction other than rotation, thus improving the flipping reliability of the display screen 21. Furthermore, in one embodiment, the shape of the guide block 222 perpendicular to the first direction and the cross-sectional shape of the slide groove 2121 perpendicular to the first direction are both T-shaped, allowing the guide block 222 to better fit with the slide groove 2121 and the guide rail 221.

[0060] Furthermore, the display screen 21 may also include a display screen fixing plate 213, which is disposed between the display screen body 211 and the display screen bracket 212 and is fixedly connected to the display screen body 211 and the display screen bracket 212 respectively, thereby better supporting the display screen body 211.

[0061] In some optional embodiments of this application, the first guide groove 2211 and the second guide groove 2212 are arranged at intervals along the circumference of the guide rail body 2214; the guide rail body 2214 also includes a third guide groove 2213 in the shape of an arc, the third guide groove 2213 is disposed between the first guide groove 2211 and the second guide groove 2212 and communicates with the first guide groove 2211 and the second guide groove 2212.

[0062] In this embodiment, by providing a third guide groove 2213, the first guide groove 2211 and the second guide groove 2212 can be connected, allowing the guide block 222 to slide between the first guide groove 2211 and the second guide groove 2212, thereby switching the display screen 21 between a retracted state and an unfolded state. Furthermore, since the third guide groove 2213 is arc-shaped, on the one hand, during the sliding process of the guide block 222 in conjunction with the third guide groove 2213, the guide block 222 can move and rotate simultaneously, thereby causing the display screen 21 to flip. On the other hand, the arc-shaped third guide groove 2213 allows the guide block 222 to smoothly switch between the first guide groove 2211 and the second guide groove 2212, thereby improving the stability and reliability of the flipping process.

[0063] It should be noted that when the guide rail 221 is cylindrical, the second guide groove 2212 is obtained by deflecting and translating the first guide groove 2211. This embodiment does not limit the deflection angle of the second guide groove 2212 relative to the first guide groove 2211; those skilled in the art can adjust it according to actual needs. In one embodiment, as shown in FIG9, the deflection angle of the second guide groove 2212 relative to the first guide groove 2211 is 90°. Specifically, the opening of the first guide groove 2211 faces to the left or right, and the opening of the second guide groove 2212 faces upward. This allows the display screen 21 to be horizontally unfolded and vertically retracted.

[0064] In some optional embodiments of this application, the first driving assembly 223 includes: a first lead screw guide sleeve 2231, a first lead screw 2232, and a first driving member 2233; a guide block 222 is fixedly connected to the first lead screw guide sleeve 2231; the first lead screw guide sleeve 2231 is sleeved on the first lead screw 2232; the first lead screw 2232 passes through the guide rail 221 and is connected to the first driving member 2233; the first driving member 2233 is fixedly connected to the handrail 1; the first driving member 2233 is used to drive the first lead screw 2232 to rotate and drive the first lead screw guide sleeve 2231 to move, so that the guide block 222 slides relative to the guide rail 221. The first lead screw 2232 extends in a horizontal direction (i.e., the first direction mentioned above).

[0065] In this embodiment, a first lead screw 2232 and a first lead screw guide sleeve 2231 are provided, with the first lead screw guide sleeve 2231 fixedly connected to the guide block 222, and the first lead screw 2232 connected to the first driving member 2233. Thus, the first driving member 2233 can drive the first lead screw 2232 to rotate, causing the first lead screw guide sleeve 2231 to move back and forth horizontally, thereby allowing the guide block 222 to slide relative to the guide rail 221, and thus enabling the display screen 21 to flip. The first driving member 2233 can be a motor.

[0066] In some optional embodiments of this application, the first drive assembly 223 further includes a reducer 2234, which is disposed between the first drive member 2233 and the first lead screw 2232, and is connected to both the first drive member 2233 and the first lead screw 2232. By providing the reducer 2234, the rotational speed of the first lead screw 2232 can be reduced, thereby allowing the first lead screw guide sleeve 2231 to move more smoothly along the first lead screw 2232, which is beneficial for improving the rotational smoothness and reliability of the display screen 21.

[0067] It should be noted that the embodiments of this application do not specifically limit the type of reducer 2234, and those skilled in the art can select it according to actual needs. In one embodiment, the reducer 2234 is a gear reducer 2234, which includes a first input shaft and a first output shaft, and the first driving member 2233 includes a first driving shaft. The first input shaft is drively connected to the first driving shaft, and the first output shaft is fixedly connected to the first lead screw 2232, thereby reliably transmitting the power of the first driving member 2233 to the first lead screw 2232, realizing the rotation of the first lead screw 2232.

[0068] In some optional embodiments of this application, as shown in FIG3, the lifting device 3 includes: a first bracket 31, a second bracket 32, and a lifting mechanism 33; the first bracket 31 is adapted to be connected to the vehicle body; the second bracket 32 ​​is connected to the armrest 1; the lifting mechanism 33 is disposed between the first bracket 31 and the second bracket 32 ​​and is connected to the first bracket 31 and the second bracket 32 ​​respectively, and the lifting mechanism 33 is used to drive the second bracket 32 ​​to move relative to the first bracket 31 and drive the armrest 1 to switch between a first position and a second position. Specifically, the second bracket 32 ​​is connected to the armrest bracket 12.

[0069] In this embodiment, a lifting mechanism 33 is provided between the first support 31 and the second support 32, and the first support 31 is connected to the vehicle body, while the second support 32 is connected to the handrail 1. Thus, under the action of the lifting mechanism 33, the second support 32 can move relative to the first support 31, thereby causing the handrail 1 to switch between a first position and a second position, meeting different user needs and improving the user experience.

[0070] In some optional embodiments of this application, the lifting mechanism 33 includes: a linkage assembly 331 and a second drive assembly 332; the linkage assembly 331 includes a first end and a second end that are opposite to each other, the first end is connected to the first bracket 31, and the second end is connected to the second bracket 32; the second drive assembly 332 is fixedly connected to the first bracket 31 and connected to the linkage assembly 331, and the second drive assembly 332 is used to drive the second end to move in a direction away from or close to the first end, so that the second bracket 32 ​​moves relative to the first bracket 31.

[0071] In this embodiment, the linkage assembly 331 provides good support and transmission stability, which helps improve the reliability and smoothness of lifting. Because a second drive assembly 332 is provided and the linkage assembly 331 is connected to it, the second end of the linkage assembly 331 can move away from or towards the first end under the drive of the second drive assembly 332. That is, the linkage assembly 331 can extend and retract, driving the second support 32 to move relative to the first support 31, thereby achieving the lifting and lowering of the handrail 1.

[0072] In one embodiment, as shown in FIG6, the linkage assembly 331 includes: a first linkage 3311, a second linkage 3312, a third linkage 3313, a fourth linkage 3314, a fifth linkage 3315, and a sixth linkage 3316; the first linkage 3311 and the second linkage 3312 are arranged intersectingly, and the intersection of the first linkage 3311 and the second linkage 3312 is hinged to the output end of the second drive assembly 332; the third linkage 3313 and the fourth linkage 3314 are respectively hinged to the first linkage 3311. At both ends of the rod 3311, the end of the third link 3313 facing away from the first link 3311 is hinged to the first bracket 31, and the end of the fourth link 3314 facing away from the first link 3311 is hinged to the second bracket 32; the fifth link 3315 and the sixth link 3316 are respectively hinged to both ends of the second link 3312, with the end of the fifth link 3315 facing away from the second link 3312 hinged to the first bracket 31, and the end of the sixth link 3316 facing away from the second link 3312 hinged to the second bracket 32. This scissor-like structure can improve the overall structural strength of the link assembly 331, not only better supporting the second bracket 32 ​​and the handrail 1 mounted on the second bracket 32, thus improving the support reliability of the handrail 1; but also making the lifting mechanism 33 more compact and stable, thus improving the lifting stability and reliability of the handrail 1.

[0073] In some optional embodiments of this application, as shown in Figures 4 and 5, the second drive assembly 332 includes: a second lead screw guide sleeve 3321, a second lead screw 3322, and a second drive member 3323; the connecting rod assembly 331 is connected to the second lead screw guide sleeve 3321; the second lead screw guide sleeve 3321 is sleeved on the second lead screw 3322; the second drive member 3323 is fixedly connected to the first bracket 31 and connected to the second lead screw 3322, and is used to drive the second lead screw 3322 to rotate and drive the second lead screw guide sleeve 3321 to move, so that the second end of the connecting rod assembly 331 moves toward or away from the first end. The second lead screw 3322 extends in a vertical direction (i.e., perpendicular to the first direction mentioned above).

[0074] In this embodiment, a second lead screw 3322 and a second lead screw guide sleeve 3321 are provided, with the second lead screw guide sleeve 3321 connected to the connecting rod assembly 331, and the second lead screw 3322 connected to the second driving member 3323. Thus, the second driving member 3323 can drive the second lead screw 3322 to rotate, causing the second lead screw guide sleeve 3321 to move vertically up and down. This causes the second end of the connecting rod assembly 331 to move towards or away from the first end, thereby extending and retracting the connecting rod assembly 331 and driving the second bracket 32 ​​to move relative to the first bracket 31, thereby achieving the lifting and lowering of the handrail 1. The second driving member 3323 can be a motor.

[0075] In one embodiment, as shown in Figures 5 and 7, the connecting rod assembly 331 and the second drive assembly 332 are respectively disposed on opposite sides of the first bracket 31, and the first bracket 31 is provided with a limiting groove 311 extending in the vertical direction. The connecting rod assembly 331 is also provided with a pin, which passes through the intersection of the first connecting rod 3311 and the second connecting rod 3312, thereby realizing the hinge connection between the first connecting rod 3311 and the second connecting rod. The second drive assembly 332 is also provided with a connecting shaft 3324, which is slidably connected to the limiting groove 311, and the two opposite ends of the connecting shaft 3324 are respectively fixedly connected to the pin and the second lead screw guide sleeve 3321. In this way, the intersection of the first connecting rod 3311 and the second connecting rod 3312 can be hinged to the output end of the second drive assembly 332, and the connecting rod assembly 331 can adaptively extend and retract during the vertical movement of the second lead screw guide sleeve 3321, thereby realizing the lifting and lowering of the handrail 1.

[0076] In some optional embodiments of this application, as shown in FIG6, the lifting mechanism 33 further includes a guide assembly 333, which includes at least two guide members 3334 that are slidably connected in sequence; wherein, the two outermost guide members 3334 are respectively connected to the first bracket 31 and the second bracket 32. In this way, it can be ensured that the lifting mechanism 33 always rises or falls in the vertical direction, effectively avoiding the problem of the handrail 1 not being able to rise or fall in place due to deviation or tilt, which is conducive to improving the lifting stability and reliability of the lifting mechanism 33.

[0077] It should be noted that the specific location and number of guide components 333 are not limited in the embodiments of this application, and those skilled in the art can adjust them according to actual needs. In one embodiment, four guide components 333 are provided, with two guide components 333 located on the side of the first bracket 31 and the second bracket 32 ​​near the connecting rod assembly 331 and symmetrically distributed on both sides of the limiting groove 311, and the other two guide components 333 located on the front and rear sides of the first bracket 31 and the second bracket 32, thereby further improving the lifting stability and reliability of the lifting mechanism 33. In addition, the number of guide members 3334 of a single guide component 333 is not limited in the embodiments of this application, and those skilled in the art can adjust them according to actual needs. In one embodiment, the guide assembly 333 is provided with three guide members 3334, which are a first guide member 3331, a second guide member 3332, and a third guide member 3333, which are slidably connected in sequence. The side of the first guide member 3331 facing away from the second guide member 3332 is fixedly connected to the first bracket 31, and the side of the third guide member 3333 facing away from the second guide member 3332 is fixedly connected to the second bracket 32. The first guide member 3331, the second guide member 3332, and the third guide member 3333 ensure that the lifting mechanism 33 always rises or falls in a vertical direction, effectively avoiding the problem of the handrail 1 not reaching its full position due to deviation or tilt, which is beneficial to improving the lifting stability and reliability of the lifting mechanism 33.

[0078] In practical applications, as shown in Figures 1 and 2, the handrail assembly 100 further includes an outer guard plate 4 and an inner guard plate 5. The outer guard plate 4 and the inner guard plate 5 are disposed on opposite sides of the handrail bracket 12 and fixedly connected to the handrail bracket 12. The outer guard plate 4 and the inner guard plate 5 enclose a receiving cavity, within which at least a portion of the lifting device 3 is disposed. Furthermore, the handrail assembly 100 also includes a control button, which is electrically connected to the first drive member 2233 and the second drive member 3323. The control button is used to control the start or stop of the first drive member 2233 and the second drive member 3323. The control button can be located on the inner guard plate 5 for user operation. Alternatively, the control button can be replaced by a control screen or other components.

[0079] The following is an example of the operation of the armrest assembly 100 according to an embodiment of this application:

[0080] When it is necessary to use the armrest 1 and display screen 21:

[0081] When the control button is activated, firstly, the control button activates the second drive member 3323 and drives the second lead screw 3322 to rotate, thereby causing the second lead screw guide sleeve 3321 to move upward, allowing the connecting rod assembly 331 to extend, and then causing the second bracket 32 ​​to move upward, so that the handrail 1 rises from the first position to the second position; secondly, the control button activates the first drive member 2233 and drives the first lead screw 2232 to rotate, thereby causing the first lead screw guide sleeve 2231 to move backward (i.e., move towards the handrail 1), so that the guide block 222 slides from the first guide groove 2211 through the third guide groove 2213 to the second guide groove 2212, thereby causing the display screen 21 to flip and switch from the retracted state to the unfolded state.

[0082] Understandably, during the above operation, after the armrest 1 reaches the second position, the control button can control the second drive component 3323 to stop or the second drive component 3323 to stop automatically; after the display screen 21 is in the unfolded state, the control button can control the first drive component 2233 to stop or the second drive component 3323 to stop automatically.

[0083] When the armrest 1 and display screen 21 are not needed:

[0084] When the control button is activated, firstly, the control button activates the first drive member 2233 and drives the first lead screw 2232 to rotate, thereby causing the first lead screw guide sleeve 2231 to move forward (i.e., move away from the handrail 1), so that the guide block 222 slides from the second guide groove 2212 through the third guide groove 2213 to the first guide groove 2211, thereby causing the display screen 21 to flip and switch from the unfolded state to the retracted state; secondly, the control button activates the second drive member 3323 and drives the second lead screw 3322 to rotate, thereby causing the second lead screw guide sleeve 3321 to move downward, so that the connecting rod assembly 331 can retract, thereby causing the second bracket 32 ​​to move downward, so that the handrail 1 descends from the second position to the first position.

[0085] It is understandable that during the above operation, after the display screen 21 is in the retracted state, the control button can control the first drive component 2233 to stop or the second drive component 3323 to stop automatically; after the handrail 1 reaches the first position, the control button can control the second drive component 3323 to stop or the second drive component 3323 to stop automatically.

[0086] In summary, the handrail assembly 100 provided in this application embodiment has at least the following advantages:

[0087] In this embodiment, a lifting device 3 and a flipping mechanism 22 are provided. The lifting device 3 can drive the armrest 1 to switch between a first position and a second position, and the flipping mechanism 22 can drive the display screen 21 to switch between an unfolded state and a retracted state. Thus, when the armrest 1 and display screen 21 are needed, the lifting device 3 can first raise the armrest 1 from the first position to the second position, and then the flipping mechanism 22 can switch the display screen 21 to the unfolded state, thereby meeting user needs and improving the comfort and entertainment of the seat. When the armrest 1 and display screen 21 are not needed, the flipping mechanism 22 can first switch the display screen 21 to the retracted state, and then the lifting device 3 can lower the armrest 1 from the second position to the first position, thereby increasing the seat space and improving the user experience.
