At the same time, in order to ensure the collision safety, the handrail needs to have the locking function, so that the handrail needs to be unlocked first and then opened when used.

[0003] At present, the more mainstream handrail unlocking system on the market is to arrange the locking mechanism in the lower shaft area of the handrail, arrange the unlocking structure in the upper part of the handrail, and use the cable to connect between the upper unlocking mechanism and the lower locking mechanism. The unlocking structure is generally divided into two kinds, one is to arrange a plastic piece buckle in the middle of the upper part of the handrail. This scheme will affect the comfort of the passengers to a certain extent, because in order to assemble and fix the buckle, a larger size structural part is needed in the handrail, which occupies a part of the space of the handrail foam, which serves as the backrest of the seat when the handrail is closed. When the passengers sit, the passengers may feel the foreign body sensation on the back, thereby affecting the comfort. The other scheme is to arrange a pull belt on the side of the handrail, which can effectively solve the problem of comfort. However, this also produces two new problems, first, the pull belt is arranged on the side, and the distance between the passengers on both sides and the position of the pull belt is different, from the human-machine angle, the operation convenience of the passenger far away is reduced. At the same time, since the pull belt is arranged on the side, an opening needs to be provided on the face cover, which affects the appearance of the handrail to a certain extent. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] As shown in Figure 1 and Figure 2 The embodiment of the application provides a handrail framework structure, which comprises two main supports 10 arranged symmetrically, a locking mechanism 20 arranged at the lower end of each main support 10, a headrest framework 30, a fixed plate 40, an unlocking mechanism 50, a cable 60 and an unlocking pull belt 70.

[0029] Specifically, the headrest framework 30 is connected with the upper ends of the two main supports 10. The fixed plate 40 is connected with the upper parts of the two main supports 10. The lower ends of the two main supports 10 are connected with the backrest framework of the seat through the locking mechanism 20, and have a locking function. The unlocking mechanism 50 is arranged on the fixed plate 40 and connected with the locking mechanism 20 through the cable 60. One end of the cable 60 is fixed on the unlocking mechanism 50, and the other end is connected with the locking mechanism 20.

[0030] Further, the headrest framework 30 can be connected with the upper ends of the main supports 10 in a detachable manner. Through this connection mode, different types of headrest frameworks 30 can be configured for the handrail according to needs.

[0031] As shown in Figure 3As shown, the unlocking mechanism 50 includes an unlocking lever 51 pivotally arranged on a pivot shaft 53 fixed on the fixed plate 40, and a reset spring 52 sleeved on the pivot shaft 53. The unlocking pull strap 70 is connected to one end of the unlocking lever 51. One end of the reset spring 52 is connected to the other end of the unlocking lever 51 away from the end connected to the unlocking pull strap 70, and the other end of the reset spring 52 is connected to the fixed plate 40. In a specific embodiment, one end of the reset spring 52 can be connected to the fixed plate 40 by hanging on a protruding structure of the fixed plate 40; the other end of the reset spring 52 can be inserted into a hole opened on the unlocking lever 51, which is located on the other end of the unlocking lever 51 away from the end connected to the unlocking pull strap 70. The upper end of the pull cable 60 is connected to the unlocking lever 51.

[0032] Further, the unlocking pull strap 70 can be detachably connected to the end of the unlocking lever 51. When the unlocking pull strap 70 is damaged, it is convenient to replace or repair; different types of unlocking pull straps 70 can also be configured for the handrail according to the needs of use.

[0033] When the user pulls the unlocking pull strap 70, the unlocking pull strap 70 pulls the end connected to the unlocking lever 51, so that the unlocking lever 51 rotates around the pivot shaft 53. At the same time, the unlocking lever 51 drives the pull cable 60 to perform an unlocking operation on the locking mechanism 20 connected to the lower end of the pull cable 60. In this process, one end of the reset spring 52 fixed on the other end of the unlocking lever 51 rotates around the pivot shaft 53 together with the unlocking lever 51, so that the reset spring 52 is in a compressed state. Then, when the user removes the pulling force applied to the unlocking pull strap 70, the unlocking lever 51 returns to the initial position under the restoring force of the reset spring 52, and the unlocking pull strap 70 returns to the state of being collected from the state of being pulled out.

[0034] Further, the two ends of the pull cable 60 can be detachably connected to the unlocking lever 51 and the locking mechanism 20, respectively. When the pull cable 60 is damaged, it is convenient to replace or repair; different types of pull cables 60 can also be configured for the handrail according to the needs of use.

[0035] Further, as shown in Figure 3 and Figure 4 The fixed plate 40 is provided with a first limiting portion 41 and a second limiting portion 42 near the end of the unlocking lever 51 connected to the reset spring 52. By providing the first limiting portion 41 and the second limiting portion 42 on the fixed plate 40, the range of rotation of the unlocking lever 51 around the pivot shaft 53 can be controlled, and the unlocking pull strap 70 is protected from being damaged due to improper operation.

[0036] As shown in Figure 3 and Figure 4As shown, the first support 43 is arranged at the middle of the upper end of the fixed plate 40, and the first rotating shaft 44 is arranged on the first support 43, and the unlocking pull belt 70 is arranged around the first rotating shaft 44. In addition, the second rotating shaft 45 is also arranged on the first support 43, and the unlocking pull belt 70 is also arranged between the first rotating shaft 44 and the second rotating shaft 45. The first rotating shaft 44 provides support for the unlocking pull belt 70, so that the user can conveniently pull the unlocking pull belt 70 to rotate around the first rotating shaft 44, reduces the operation force of pulling the unlocking pull belt 70 to unlock, makes the unlocking process more smooth, and improves the experience of the passenger. The gap formed by the cooperation of the second rotating shaft 45 and the first rotating shaft 44 can limit the arrangement mode (for example, the direction of the unlocking pull belt 70) of the unlocking pull belt 70, so that the exposed part of the unlocking pull belt 70 (that is, the end of the unlocking pull belt 70 for the user to pull and the part of the unlocking pull belt 70) can be attached to the outer surface of the armrest, so that the appearance of the seat is better.

[0037] The first support 43 provided with the first rotating shaft 44 and the second rotating shaft 45 is arranged at the middle of the upper end of the fixed plate 40, so that the unlocking pull belt 70 can be arranged at the middle of the upper end of the fixed plate 40. If the unlocking pull belt 70 is arranged at one side of the armrest, although the user sitting close to the unlocking pull belt 70 is convenient to operate the unlocking pull belt 70; however, the user sitting away from the unlocking pull belt 70 is not convenient to operate the unlocking pull belt 70 to unlock the armrest. The embodiment of the present application arranges the unlocking pull belt 70 at the middle of the armrest, so that the passengers sitting on the seats on both sides of the armrest are convenient to operate the unlocking pull belt 70 to unlock and open the armrest, and the experience of the user is improved.

[0038] In addition, compared with the existing way of arranging a plastic buckle on the armrest and opening the armrest by pulling the buckle, the way of unlocking the armrest by cooperating the unlocking pull belt 70 with the unlocking mechanism 50 in the embodiment of the present application not only improves the convenience of the user to open the armrest; and when the passenger sits at the corresponding position of the armrest and leans against the armrest, because there is no plastic buckle, the comfort of the passenger is improved; in addition, the cost of the armrest is reduced and the complexity of the assembly of the armrest is reduced because the plastic buckle is cancelled.

[0039] The embodiment of the present application also provides an armrest, which comprises the armrest framework structure, the armrest foam and the armrest cover as described above. The armrest foam is wrapped outside the armrest framework structure, and the armrest cover is sleeved outside the armrest foam. The armrest framework structure, the armrest foam and the armrest cover jointly constitute the armrest assembly.

[0040] Further, the handrail cover is provided with an opening at a position corresponding to the unlocking pull belt 70, and the free end of the unlocking pull belt 70 is pulled out from the opening, so that the passenger can pull the unlocking pull belt 70 to unlock the handrail. As shown in Figure 5 the opening of the handrail cover is arranged at a middle position of a gap formed by the intersection of the outer contour line of the middle part of the handrail and the outer contour line of the headrest part of the handrail. The unlocking pull belt 70 is pulled out from the gap, which well conceals the internal structure of the handrail and improves the appearance of the handrail.

[0041] The handrail skeleton structure and the handrail in the embodiments of the present application can be unlocked and opened by the cooperation of the unlocking pull belt 70 and the unlocking mechanism 50. The unlocking pull belt 70 is arranged at a middle position of the upper part of the handrail, and a part of the unlocking pull belt 70 is pulled out from the gap between the middle part of the handrail and the headrest part, and the other part is connected with the unlocking mechanism 50 inside the handrail. The unlocking pull belt 70 pulls the unlocking rod 51 and drives the pull rope 60 to finally unlock the locking mechanism 20 and unlock the handrail. Compared with the unlocking scheme of arranging a plastic handrail on the handrail, the embodiments of the present application improve the comfort of the handrail. Compared with the scheme of arranging the unlocking pull belt 70 on the side of the handrail, the embodiments of the present application not only solve the problem of poor appearance of the handrail caused by the exposed outlet of the unlocking pull belt 70, but also solve the problem of inconvenient operation of the passenger on one side of the seat caused by arranging the unlocking pull belt 70 on the side of the handrail, thereby improving the human-machine use experience.

[0042] The embodiments of the present application further provide a seat, which comprises the handrail as described above.

[0043] The embodiments of the present application further provide a vehicle, which comprises the seat as described above. The seat is usually a second-row and / or third-row seat in the vehicle.

[0044] So far, the technical scheme of the present application has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical schemes after the changes or replacements will fall within the protection scope of the present application.
