DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] See also Figure 1-6 The utility model provides a technical solution: an inward-opening handle assembly with a buffering function, including a mounting shell 1, a handle 2, a return spring 3, a rotating shaft 4, a friction ball 5, a buffer block 6, a support block 7, a rotating plate 8, a soft pressure block 9, a spring 10, a protective plate 11, a sliding ball 12, a piston 13, a slide groove 14, and an air guide tube 15.
[0031] Embodiment 1: The inward opening handle 2 assembly with a buffer function is provided with an anti-bending structure, which can limit the speed of the handle 2 when it is pulled up to avoid bending when it is pulled up too quickly, specifically:
[0032] The upper surface of the mounting shell 1 is provided with a slot, the lower surface of the handle is rotatably connected to the rotating shaft through a connecting piece, and the two ends of the rotating shaft 4 are rotatably mounted on the inner wall surface of the mounting shell 1, and the outer surface of the rotating shaft 4 is installed with a return spring 3, the lower surface of the protective plate 11 is set to a soft silicone material, and the protective plate 11 is connected to an anti-bending structure, and the anti-bending structure includes a slide groove 14, the slide groove 14 is set on the lower surface of the protective plate 11, and the slide groove 14 is slidably installed with a sliding ball 12, and the lower end of the sliding ball 12 is connected to a piston 13, and the piston 13 is embedded in the interlayer of the mounting shell 1, and the lower surface of the piston 13 is connected with an air guide pipe 15, and the sliding ball 12 is set to a sphere, and the sliding ball 12 rotates in the slide groove 14;
[0033] When the inner opening handle assembly 2 with a buffer function is used, first, Figure 1 When the hand is inserted into the gap between the mounting shell 1 and the handle 2, the handle 2 is pulled out, so that the handle 2 rotates through the rotating shaft 4. At this time, a protective plate 11 is rotatably mounted on the upper surface of the mounting shell 1, so the handle 2 will drive the protective plate 11 to rotate. Since the lower surface of the protective plate 11 is set to a soft silicone material, it will not cause damage to the upper surface of the handle 2. When the protective plate 11 rotates upward, Figure 6 As shown, the protective plate 11 will drive the sliding ball 12 to move upward and slide through the slide groove 14, so that the sliding ball 12 pulls up the piston 13, and the air flow inside the piston 13 will flow through the air duct 15. The size of the air duct 15 will limit the surge of air flow, so that the rotation of the protective plate 11 can be controlled to avoid excessive rotation, thereby preventing the passenger from accidentally using too much force when opening the door. The reaction force on the handle 2 will be applied to the handle 2 through the rotating arm, causing the handle 2 to break at the overlap of the rotating arm.
[0034] Embodiment 2: The inner opening handle 2 assembly with a buffering function is also provided with a buffering structure, which can reduce the impact of the handle 2 during the reset time and avoid damage, specifically:
[0035] A buffer structure is installed inside the mounting shell 1, and the buffer structure includes a friction ball 5, and a buffer block 6 is installed on the lower surface of the handle 2, and a support block 7 is fixedly installed on the bottom surface of the inner wall of the mounting shell 1. The upper end of the support block 7 is rotatably connected to a rotating plate 8, and the lower surface of the rotating plate 8 is connected to a spring 10, and the lower end of the spring 10 is fixedly installed on the bottom surface of the inner wall of the mounting shell 1. A soft pressure block 9 is arranged between the two support blocks 7, and the upper part of the soft pressure block 9 corresponds to the buffer block 6, and the lower end of the buffer block 6 is arranged to be a semicircular structure;
[0036] When the handle 2 is released, the return spring 3 installed on the outer surface of the shaft 4 will drive the handle 2 to return to its original position. Due to the excessive rotation, an impact will be generated. Figure 4As shown, the friction balls 5 are installed at equal intervals on the side surface of the handle 2, so the friction balls 5 will generate friction with the inner wall surface of the mounting shell 1 to slow down the rotation speed. Further, the buffer block 6 on the lower surface of the handle 2 will press the two rotating plates 8, as shown in FIG. Figure 5 As shown, the rotating plate 8 uses the support block 7 as a fulcrum and one end rotates downward, and the other end of the rotating plate 8 will pull the spring 10 installed on the lower surface, so that the tension of the spring 10 produces resistance to the buffer block 6 pressing the rotating plate 8, so that the handle 2 is buffered, and a soft pressure block 9 is correspondingly installed under the buffer block 6 to avoid collision, so that the handle 2 is reset to reduce the impact force.
[0037] Working principle: When using the inward-opening handle 2 assembly with a buffering function, an anti-bending structure is provided, which can drive the piston 13 to stretch and limit the rotation speed of the handle 2 through the protective plate 11. A buffering structure is also provided, which can press the rotating plate 8 to rotate the pulling spring 10 through the buffer block 6 when the handle 2 is rotated and recovered to reduce the impact force, thereby increasing the overall practicality.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
