DETAILED DESCRIPTION

[0027] In order to better understand the purpose, structure and function of the utility model, the utility model of a handrail fixed framework is further described in detail below in combination with the drawings.

[0028] As shown in Figure 1 , Figure 2 , it shows a handrail fixed framework of the utility model embodiment, which comprises a handrail frame 1 rotatably connected with the outer wall of the car seat, a sliding groove 4 is formed on the lower bottom surface of the handrail frame 1, a moving seat 5 is slidably connected in the sliding groove 4, the moving seat 5 is rotatably connected with one side of the extension frame 3, the extension frame 3 is accommodated in the handrail frame 1, and the handrail frame 1 is provided with an opening 20 on the side away from the moving seat 5 for the extension frame 3 to be pulled out of the handrail frame 1.

[0029] Specifically, the handrail fixed framework of the embodiment comprises a handrail frame 1, a rotating shaft 2 is fixedly connected with the outer wall of the handrail frame 1, and the handrail frame 1 is rotatably connected with the outer wall of the car seat through the rotating shaft 2, wherein the handrail frame 1 is a hollow structure surrounded by an upper surface, a lower bottom surface and four side surfaces, and the side surface close to the rotating shaft 2 is a curved surface.

[0030] The extension frame 3 is arranged in the handrail frame 1, and the extension frame 3 is rotatably connected with the moving seat 5, and in the process of being pulled out of the handrail frame 1, the extension frame 3 will drive the moving seat 5 to move in the sliding groove 4, that is, the sliding groove 4 is arranged to limit the movement track of the moving seat 5; the handrail frame 1 is provided with an opening 20 on the side away from the moving seat 5 for the extension frame 3 to be pulled out of the handrail frame 1, and after the extension frame 3 is pulled out of the handrail frame 1 through the opening 20, the extension frame 3 will not fall due to the moving seat 5 being located in the sliding groove 4.

[0031] The extension frame 3 and the moving seat 5 are rotatably connected, so that after the extension frame 3 is pulled out of the handrail frame 1 through the aforementioned opening 20, the extension frame 3 can be rotated, for example, to be rotated to the front of the body, so as to facilitate the taking and using of articles; and when the extension frame 3 is not needed to be used, the extension frame 3 can be accommodated in the handrail frame 1 through the cooperation of the moving seat 5 and the sliding groove 4, thereby improving the diversity and convenience of the use of the handrail frame 1.

[0032] As shown in Figure 3 , a resistance assembly is arranged between the extension frame 3 and the handrail frame 1, and the resistance assembly is used for resisting the pulling out and retracting of the extension frame 3 and limiting the extension frame 3 at any position in the handrail frame 1. The arrangement of the resistance assembly in the embodiment avoids the extension frame 3 from being pulled out of the handrail frame 1 without human pulling, and after the extension frame 3 is partially pulled out of the handrail frame 1, the resistance assembly can limit the extension frame 3 at the position in the handrail frame 1.

[0033] In an embodiment, as shown in Figure 3 , Figure 4As shown, the inner wall of the handrail frame 1 is fixedly connected with a magnet one 6, and the side wall of the moving seat 5 away from the expansion frame 3 is fixedly connected with a magnet two 7. The magnet one 6 and the magnet two 7 are magnetically connected to make the expansion frame 3 stored in the handrail frame 1.

[0034] The magnet one 6 and the magnet two 7 are magnetically connected to make the expansion frame 3 stored in the handrail frame 1.

[0035] In an embodiment, the upper surface of the handrail frame 1 is provided with a circular hole 19. After the expansion frame 3 is pulled out of the handrail frame 1 to the limit position, the magnet two 7 is located between the opening 20 and the circular hole 19.

[0036] The circular hole 19 is used to place a water cup. Since the moving shaft is clamped in the sliding groove 4, and the magnet two 7 is arranged on the side wall of the moving seat 5 away from the expansion frame 3, the expansion frame 3 needs to meet the demand of placing a water cup after being completely pulled out of the handrail frame 1. The magnet two 7 is arranged to be located between the opening 20 and the circular hole 19 after the expansion frame 3 is pulled out of the handrail frame 1 to the limit position. In this case, the water cup is placed on the lower bottom surface of the handrail frame 1 through the circular hole 19. For this case, the limit position of the magnet two 7 is that the edge of the magnet two 7 is aligned with the edge of the circular hole 19 of the handrail frame 1.

[0037] In an embodiment, as shown in the drawings, Figure 3 The expansion frame 3 is provided with a containing groove 16 corresponding to the circular hole 19. The inner wall of the containing groove 16 is fixedly connected with an anti-skid strip 17, and the groove bottom of the containing groove 16 is attached with a water absorption pad 18.

[0038] The containing groove 16 is used to contain the water cup passing through the circular hole 19. The position of the containing groove 16 needs to correspond to the position of the circular hole 19. For example, after the expansion frame 3 is completely stored in the handrail frame 1, the containing groove 16 is just located directly below the circular hole 19. Or, after the expansion frame 3 is partially pulled out of the handrail frame 1, the containing groove 16 is just located directly below the circular hole 19.

[0039] Again, the anti-skid strip 17 is a plurality of anti-skid strips. The anti-skid strip 17 is arranged on the inner wall of the containing groove 16, and is used to prevent the water cup from sliding in the containing groove 16. In specific implementation, for example, the anti-skid strip 17 is arranged in a semi-cylindrical shape. The water absorption pad 18 is used to absorb the condensed water flowing down the cup wall when the ice drink is placed in the containing groove 16, so as to avoid the situation that the containing groove 16 needs to be wiped later due to water accumulation.

[0040] Finally, the expansion frame 3 is provided with a storage groove. The storage groove is used to place articles. The bottom of the storage groove can be provided with an anti-skid strip 17 or a weight-reducing hole as needed.

[0041] In an embodiment, as shown in the drawings, Figure 6As shown, the extension frame 3 is fixedly connected with a fixed seat 21 close to one end of the moving seat 5, the moving seat 5 is fixedly connected with a fixed block 22 close to one side of the extension frame 3, the fixed seat 21 and the fixed block 22 are rotationally connected through a connecting shaft, the connecting shaft is limited on the fixed seat 21, the axis direction of the connecting shaft is perpendicular to the upper surface of the handrail frame 1, and the extension frame 3 can rotate in a rotation plane parallel to the upper surface of the handrail frame 1 after being pulled out of the handrail frame 1.

[0042] In the embodiment, the extension frame 3 and the moving frame are connected through the fixed block 22, the fixed seat 21 and the connecting shaft, for the connecting shaft, for example, the upper end and the lower end of the connecting shaft exposed from the fixed seat 21 or the fixed block 22 are respectively connected with a nut, so that the connecting shaft is limited on the fixed seat 21. Wherein, the axis direction of the connecting shaft is perpendicular to the upper surface of the handrail frame 1, therefore, after the extension frame 3 is pulled out of the handrail frame 1, the extension frame 3 can rotate around the connecting shaft as the pivot, that is, the rotation plane of the extension frame 3 is parallel to the upper surface of the handrail frame 1, and the connecting shaft is limited on the fixed seat 21, therefore, the extension frame 3 can be prevented from being separated from the moving seat 5 after being pulled out of the handrail frame 1, that is, the situation that the extension frame 3 falls after being pulled out is avoided.

[0043] Wherein, as shown in Figure 5 , Figure 6 shown, the part close to the moving seat 5 of the extension frame 3 is provided with a mounting groove 8, the mounting groove 8 is fixedly connected with a fixed rod 13, the fixed rod 13 is fixedly connected with a circular ring 23, and the part of the circular ring 23 exposed outside the mounting groove 8 is connected with a toothed section 12; the moving seat 5 is provided with a fixed groove 9, the fixed groove 9 is fixedly connected with a supporting shaft 10, the axis of the supporting shaft 10 is parallel to the upper surface of the handrail frame 1, the supporting shaft 10 is rotationally connected with a gear 11, and the gear 11 is meshingly connected with the toothed section 12.

[0044] In the embodiment, the extension frame 3 is fixedly connected with the circular ring 23, the circular ring 23 is provided with the toothed section 12, the supporting shaft 10 is fixedly connected with the moving seat 5, the gear 11 is sleeved outside the supporting shaft 10 and can rotate around the axis of the supporting shaft 10, the gear 11 has no displacement along the axis direction of the supporting shaft 10, and the gear 11 and the toothed section 12 are meshed with each other.

[0045] In use, when the extension frame 3 is pulled out of the armrest frame 1, the extension frame 3 is pivoted about the connecting shaft 2, the extension frame 3 drives the gear segment 12 to rotate, and the gear segment 12 drives the gear 11 to rotate, so that the extension frame 3 can be pivoted to a corresponding position, for example, in front of the user, according to the needs. When the extension frame 3 is pivoted to the target position, the engagement force between the gear 11 and the gear segment 12 can provide the extension frame 3 with the switching-limiting function in the absence of external force. Alternatively, other structures can be adopted to keep the extension frame 3 at the target position after being pivoted to the target position.

[0046] In an embodiment, as shown in Figure 3 The resistance assembly includes at least one blocking block 14 and a plurality of rubber blocks 15. The blocking block 14 is fixed on one of the side walls of the sliding groove 4 in the armrest frame 1, and the rubber blocks 15 are evenly distributed on the corresponding sides of the extension frame 3. The blocking block 14 and the rubber blocks 15 cooperate to hinder the extension frame 3 from being pulled out and retracted, and to limit the extension frame 3 at any position in the armrest frame 1.

[0047] In this embodiment, the blocking block 14 and the rubber blocks 15 cooperate to hinder the extension frame 3 from being pulled out and retracted. The rubber blocks 15 are made of rubber, have anti-slip properties, and can be deformed. Specifically, during the process of pulling the extension frame 3 out of the armrest frame 1, the rubber blocks 15 on the extension frame 3 need to pass through the blocking block 14 of the armrest frame 1 in sequence. During the process of storing the extension frame 3 in the armrest frame 1, the rubber blocks 15 on the extension frame 3 again pass through the blocking block 14 of the armrest frame 1 in sequence. For both the process of pulling the extension frame 3 out and the process of storing the extension frame 3 in the armrest frame 1, the pulling force applied by the user is used to deform the rubber blocks 15 to pass through the blocking block 14 after the rubber blocks 15 come into contact with the blocking block 14.

[0048] In an embodiment, as shown in Figure 3 The side of the blocking block 14 close to the moving seat 5 and the side of each rubber block 15 away from the moving seat 5 are straight planes 24 perpendicular to the movement direction of the moving seat 5. The side of each rubber block 15 close to the moving seat 5 is an inclined plane 25, and the side of the blocking block 14 away from the moving seat 5 is provided with a matching surface abutting against the inclined plane 25.

[0049] Specifically, during the process of pulling out the extension frame 3, the rubber block 15 of the extension frame 3 deforms through the blocking block 14 of the handrail frame 1 in sequence, and the rubber block 15 of the extension frame 3 and the blocking block 14 of the handrail frame 1 are in contact with the straight plane 24, so that a large pulling force is required to deform the rubber block 15; when the extension frame 3 is pushed into the handrail frame 1, the rubber block 15 of the extension frame 3 and the blocking block 14 of the handrail frame 1 are in contact with the inclined plane 25 and the matching surface, so that a small pushing force can deform the inclined plane 25 of the rubber block 15 to pass through the matching surface of the blocking block 14. The setting of the embodiment makes the resistance to pulling out the extension frame 3 greater than the resistance to retracting the extension frame 3, thereby avoiding the extension frame 3 from extending out of the handrail frame 1 without human pulling on one hand, and facilitating the retraction of the extension frame 3 pulled out of the handrail frame 1 into the handrail frame 1 on the other hand.

[0050] When the extension frame 3 is pulled out of the handrail frame 1, the pulling force makes the magnet two 7 separate from the magnetic attraction of the magnet one 6, and in the process of gradually moving the extension frame 3 out of the handrail frame 1, the blocking block 14 will be in contact with the rubber block 15, and the two are in contact with the straight plane 24 and the straight plane 24, so a large pulling force is required; when the extension frame 3 is partially pulled out of the handrail frame 1, and no pulling force is applied to the extension frame 3, the blocking block 14 will provide a certain limiting function for the extension frame 3, so that the extension frame 3 remains at this position; when the extension frame 3 is partially pulled out of the handrail frame 1 to align the circular hole 19 of the handrail frame 1 and the accommodating groove 16 of the extension frame 3, the water cup or other drinks can be placed in the accommodating groove 16 through the circular hole 19; when the extension frame 3 is completely pulled out of the handrail frame 1, the setting of the sliding groove 4 makes the moving seat 5 not separate from the handrail frame 1, and the extension frame 3 also does not separate from the moving seat 5, and then the extension frame 3 is moved, the toothed section 12 drives the gear 11 engaged therewith to rotate, at this time the extension frame 3 can rotate, for example, to the front of the user, and provides the requirement of accommodating food or articles for the user during long-distance driving.

[0051] The handrail fixed framework of the embodiment of the utility model cooperates the sliding groove 4, the moving seat 5 and the extension frame 3, so that the extension frame 3 can move in the handrail frame 1, and the extension frame 3 can rotate after being pulled out of the handrail frame 1, for example, to the front of the user, thereby improving the diversity and convenience of the use of the handrail frame 1.

[0052] The cooperation of the blocking block 14 and the rubber block 15 avoids the extension frame 3 from extending out of the handrail frame 1 without human pulling, and after the extension frame 3 is partially pulled out of the handrail frame 1, the cooperation of the blocking block 14 and the rubber block 15 can limit the extension frame 3 at this position in the handrail frame 1.

[0053] The water absorption pad 18 is arranged to absorb condensed water flowing down the cup wall when the ice drink is placed inside the containing groove 16, thereby avoiding the need for later wiping due to water accumulation inside the containing groove 16.
