[0033] See also Figure 1-12A multi-directional adjustable frame passenger auxiliary tool comprises a mounting frame 1, which is used to be mounted on a carrier. The mounting frame 1 is provided with an adjustment rod 2, a headrest seat 3, and a siderest seat 4. The adjustment rod 2 can be slid forward and backward and is arranged on the mounting frame 1. The headrest seat 3 can be slid up and down and is arranged on the adjustment rod 2. The siderest seat 4 can be rotatably arranged on the headrest seat 3. The headrest seat 3 is used to support the user's back leaning, and the siderest seat 4 is used to support the user's side leaning. A first locking mechanism 5 is provided on the mounting frame 1, and a first locking portion 8 corresponding to the first locking mechanism 5 is provided on the adjustment rod 2. After the adjustment rod 2 slides on the mounting frame 1 to adjust its position, the first locking mechanism 5 is used to lock the adjustment rod 2. A second locking mechanism 6 is provided on the adjustment rod 2, and a second locking portion 9 corresponding to the second locking mechanism 6 is provided on the headrest seat 3. After the headrest seat 3 slides on the adjustment rod 2 to adjust its position, the second locking mechanism 6 is used to lock the headrest seat 3. The headrest seat 3 is provided with a rotating mechanism 7, and the headrest seat 3 and the side pillow seat 4 are rotated in steps through the rotating mechanism 7. The user can slide the adjustment rod 2 forward and backward and lock it through the first locking mechanism 5 to adjust the front and rear positions of the headrest seat 3 and the side pillow seat 4. The user can slide the headrest seat 3 up and down and lock it through the second locking mechanism 6 to adjust the up and down positions of the headrest seat 3 and the side pillow seat 4. The user can rotate the side pillow seat and lock it through the rotating mechanism 7 to adjust the support angle of the side pillow seat 4 for the user. The overall adjustable range is wide and the applicability is better.

[0034] Specifically, the mounting frame 1 is formed with a first slide groove 101, and the rear end of the adjustment rod 2 is inserted into the first slide groove 101 and can slide forward and backward on the first slide groove 101. The headrest seat 3 is connected with a second sliding member 201, and the adjustment rod 2 is provided with a second slide rail 202, and the second sliding member 201 can slide up and down on the second slide rail 202. The headrest seat 3 is connected with a shaft sleeve 301, and the side pillow seat 3 is connected with a rotating shaft 302, and the rotating shaft 302 is rotatably connected to the shaft sleeve 301.

[0035] like Figure 1 As shown, side pillow seats 4 are provided on both sides of the left and right sides of the headrest seat 3, and the user can lean on either side.

[0036] Preferably, the side pillow seat 4 can be horizontally rotatably arranged on the headrest seat 3, and when the supporting angle of the side pillow seat 4 is adjusted horizontally, the user can more easily obtain a comfortable supporting point.

[0037] In order to make the headrest seat 3 and the side pillow seat 4 more comfortable when supporting the user, soft pillow covers 10 are fixed on the headrest seat 3 and the side pillow seat 4.

[0038] In the embodiment of the present invention, the first locking part 8 includes a first locking groove 801 formed on the rear end of the adjusting rod 2 at a front-to-back interval. The first locking mechanism 5 includes a ball sleeve 501 sleeved on the rear end of the adjusting rod 2, and a locking sleeve 502 is sleeved on the outer side of the ball sleeve 501, and an elastic reset member 503 is connected to the outer side of the locking sleeve 502. Pull the elastic reset member 503 to make the elastic reset member 503 elastically deform, and the locking sleeve 502 is separated from the ball 504 on the ball sleeve 501, and the first locking part 8 and the ball sleeve 501 can slide with each other to adjust the position of the adjusting rod 2 forward and backward. After adjusting the position of the adjusting rod 2, release the elastic reset member 503 to make the elastic reset member 503 recover its deformation, and the locking sleeve 502 pushes the ball 504 on the ball sleeve 501 into the corresponding first locking groove 801, and the first locking part 8 and the ball sleeve 501 cannot slide with each other, so as to lock the adjusting rod 2 on the mounting frame 1. The first locking portion 8 can be loosened and locked by pulling the elastic reset member 503 and releasing the elastic reset member 503. The control method is simple. The ball sleeve 501 is used to prevent the adjustment rod 2 from moving in the front-rear direction when the first locking portion 8 is locked, and the structure is more stable.

[0039] In the embodiment of the present invention, the second locking mechanism 6 includes a second locking block 601 and a second lock body 602, and the second locking block 601 has two locking positions on the second lock body 602. When the second locking block 601 is located at the first locking position on the second lock body 602, the second locking block 601 locks the second locking portion 9 to restrict the second sliding member 201 from sliding on the second slide rail 202; when the second locking block 601 is located at the second locking position on the second lock body 602, the second locking block 601 is separated from the second locking portion 9, and the second sliding member 201 can slide up and down on the second slide rail 202, and the locking method is simple.

[0040] Furthermore, the second locking part 9 includes a second fixing block 901, on which a plurality of second locking grooves 902 are formed at intervals, and the spacing direction of the plurality of second locking grooves 902 on the second fixing block 901 is consistent with the sliding direction of the second sliding member 201 on the second slide rail 202. The second locking block 601 has a second locking protrusion 603, and when the second locking block 601 is located at the second locking position on the second lock body 602, the second locking protrusion 603 is inserted into the corresponding second locking groove 902 to restrict the second sliding member 201 from sliding on the second slide rail 202. By inserting the second locking protrusion 603 into the second locking groove 902, the headrest seat 3 is locked, and the headrest seat 3 is not easy to move in the up and down direction.

[0041] Fig. 9 The plurality of second locking grooves 902 are arranged in an up-and-down direction on the second fixing block 901 .

[0042] Further, the second lock block 601 can be slidably arranged on the second lock body 602. The second lock body 602 is formed with a first card slot 604 and a second card slot 605, and the direction in which the first card slot 604 and the second card slot 605 are arranged at intervals on the second lock body 602 is consistent with the sliding direction of the second lock block 601 on the second lock body 602. The second lock block 601 is connected to a second elastic member 606, and a card block 607 is connected to one end of the second elastic member 606 away from the second lock block 601. When the second lock block 601 is located at the first card position on the second lock body 602, the card block 607 is correspondingly carded into the first card slot 604. When the second lock block 601 is located at the second card position on the second lock body 602, the card block 607 is correspondingly carded into the second card slot 605. When the second locking block 601 is changed from the first locking position to the second locking position, the second elastic member 606 is subjected to elastic deformation, so that the locking block 607 is separated from the first locking slot 604; until the locking block 607 corresponds to the second locking slot 605, the second elastic member 606 is elastically deformed and the locking block 607 is pushed to lock the locking block 607 into the second locking slot 605. After the locking block 607 is separated from the first locking slot 604 or the second locking slot 605, the resistance of the second locking block 601 when sliding on the second lock body 602 is small; after the locking block 607 is locked in the first locking slot 604 or the second locking slot 605, the resistance of the second locking block 601 when sliding on the second lock body 602 is large. The design of the card block 607, the first card slot 604 and the second card slot 605 allows the user to judge whether the second lock block 601 is correspondingly located at the first card position and the second card position on the second lock body 602 by the resistance generated by the card block 607 being inserted into the first card slot 604 and the second card slot 605 when the user changes the second lock block 601 between the first card position and the second card position. The judgment method is simple and accurate. After the card block 607 is inserted into the first card slot 604 or the second card slot 605, it is not easy for the position between the second lock block 601 and the second lock body 602 to change when the user leans on the headrest seat 3.

[0043] Figure 7 The first locking slot 604 and the second locking slot 605 are arranged in a direction of being spaced apart on the second lock body 601 in a front-to-back direction.

[0044] In the embodiment of the present invention, a slot 608 matching the shape of the front end of the adjusting rod 2 is formed on the rear side of the second locking block 601, and the front end of the adjusting rod 2 is correspondingly engaged in the slot 608. A locking block slide groove 609 is formed on the rear side of the second lock body 602, and the second locking block 601 can slide forward and backward in the locking block slide groove 609. The second locking protrusion 603 is located on the front side of the second locking block 601. The front side of the second lock body 602 is connected to the rear side of the second slide rail 202. A second locking protrusion connecting groove 610 is penetrated from front to back on the front side of the second slide rail 202, and the second locking protrusion connecting groove 610 is connected to the locking block slide groove 609 and corresponds to the second locking protrusion 603. A fixed block mounting groove 611 is formed on the rear side of the second sliding member 201, and the second fixed block 901 is mounted on the fixed block mounting groove 611, and the second locking groove 902 is located on the rear side of the second fixed block 901. The first card slot 604 and the second card slot 605 are located on the side surface adjacent to the front side of the second lock body 602 on the second lock body 601, and the first card slot 604 and the second card slot 605 are arranged at intervals in front and back, and the first card slot 604 and the second card slot 605 are both connected to the lock block slide slot 609. The second elastic member 606 can be elastically deformed toward the inner side of the second lock block 601 on the second lock block 601, and deformed and restored toward the outer side of the second lock block 601. When the second lock block 601 is located at the first card position on the second lock body 602, the second elastic member 606 is deformed and restored toward the outer side of the second lock block 601, and the card block 607 is correspondingly inserted into the first card slot 604. When the second lock block 601 is located at the second card position on the second lock body 602, the second elastic member 606 is deformed and restored toward the outer side of the second lock block 602, and the card block 607 is correspondingly inserted into the second card slot 605. When the headrest seat 3 needs to be adjusted, the second lock body 602 only needs to be pulled forward to make the second lock block 601 on the second lock body 602 at the second position, and after sliding the headrest seat 3 up and down, the second lock body 602 is pushed backward to make the second lock block 601 on the second lock body 602 at the first position to lock the headrest seat 3. The control process is simple and the structure is stable. To achieve the purpose of making the second lock block 601 on the second lock body 602 at the second position, the second lock body 602 can be pulled, or the second slide rail 202, the second slide member 201, the headrest seat 3, and the components connected to the headrest seat 3 can be pulled. The more convenient way is to pull the headrest seat 3.

[0045] Further, the second lock block 601 is also connected with an anti-slip block 612. The second lock body 602 is correspondingly formed with an anti-slip groove 613 that cooperates with the anti-slip block 612. The anti-slip groove 613 is connected to the lock block groove 609, and the anti-slip groove 613 is located on the side adjacent to the front side of the second lock body 602 on the second lock body 602, and the anti-slip block 612 can slide forward and backward on the anti-slip groove 613. When the second lock block 601 is located in the second card position on the second lock body 602, the rear side of the anti-slip block 612 is against the inner wall of the anti-slip groove 613. It is prevented that when the user changes the second lock block 601 from the first card position to the second card position, the second lock block 601 is separated from the second lock body 602 due to excessive force. Preferably, the front side of the anti-slip block 612 is chamfered to facilitate the anti-slip block 612 to enter the anti-slip groove 613.

[0046] Furthermore, a spring mounting hole 614 is formed on the front side of the second slide rail 202, a spring 615 is arranged in the spring mounting hole 614, and a positioning ball 616 is arranged at the opening of the spring mounting hole 614. A plurality of positioning grooves 617 are formed vertically at intervals on the front side of the second fixing block 901. When the second locking block 601 is located at the second locking position on the second lock body 602, the spring 615 pushes the positioning ball 616 so that a part of the positioning ball 616 is located on the spring mounting hole 614, and another part of the positioning ball 616 is located on the positioning groove 617. The design of the spring mounting hole 614, the spring 615, the positioning ball 616 and the positioning groove 617 enables the spring 615 to push the positioning ball 616 into the corresponding positioning groove 617 after the position of the headrest seat 3 is adjusted by sliding up and down, so as to perform pre-tightening and positioning, so as to facilitate the locking of the headrest seat 3 by the second locking mechanism 6.

[0047] Preferably, the positioning groove 617 is consistent with the shape of the second locking groove 902. The spacing direction of the positioning groove 617 and the second locking groove 902 on the second fixed block 901 is consistent with the sliding direction of the second sliding member 201 on the second slide rail 202, and the positioning groove 617 is located in the middle of two adjacent second locking grooves 902. The second locking protrusion 603 and the positioning ball 616 can share the same groove, that is, the second locking protrusion 603 can be correspondingly inserted into the positioning groove 617, and the positioning ball 616 can be correspondingly inserted into the second locking groove 902, the spacing of the up and down adjustment can be set closer, and the number of grooves can be reduced, which is more convenient for production.

[0048] In the embodiment of the present invention, the rotating shaft 302 is a hollow shaft, and a rotating shaft through groove 701 connected to the inner side of the rotating shaft 302 is provided on the outer side of the rotating shaft 302. The rotating mechanism 7 includes a return spring 702 and a rotating block 703 provided on the inner side of the rotating shaft 302. The rotating block 703 is connected with an arc-shaped positioning portion that can pass through the rotating shaft through groove 701. The inner ring of the sleeve 301 is provided with a plurality of arc-shaped grooves. The rotating shaft 302 is rotated to align the rotating shaft through groove 701 with the arc-shaped groove, and the return spring 702 is elastically deformed and restored, so as to clamp the arc-shaped positioning portion into the arc-shaped groove.
