Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] The balance limiting device provided by this application includes: an outer tube having an opening; a connector installed at the opening; a buffer member disposed in the outer tube and fixed to the connector; a plug disposed in the outer tube and disposed opposite to the buffer member; a flocked helical spring abutted between the plug and the buffer member; a wire, one end of which is fixed to the plug and the other end of which passes through the flocked helical spring and the buffer member along the extending direction of the outer tube; a limiting member disposed between the two ends of the wire; wherein, when a pulling force acts on the other end of the wire, the limiting member can abut against the buffer member. In this way, the balance limiting device can eliminate noise and abnormal noise during the opening and closing of the ground door.

[0036] Please refer to Figures 1 - 4 , Figure 1 which is a schematic structural diagram of the balance limiting device provided by the embodiment of this application, Figure 2 is Figure 1 a cross-sectional view of the balance limiting device at A-A, Figure 3 which is an exploded schematic diagram of the balance limiting device provided by the embodiment of this application, Figure 4It is a schematic structural diagram of the outer tube provided by an embodiment of the present application. The balance limiting device 100 may include, but is not limited to, an outer tube 110, a connector 120, a buffer 130, a plug 140, a flocked helical spring 150, a wire 160, and a limiting member 170. The outer tube 110 has an opening 111. The connector 120 is installed at the opening 111. The buffer 130 is disposed in the outer tube 110 and fixed to the connector 120. The plug 140 is disposed in the outer tube 110 and is oppositely arranged with the buffer 130. The flocked helical spring 150 abuts between the plug 140 and the buffer 130. One end of the wire 160 is fixed to the plug 140. The other end of the wire 160 passes through the flocked helical spring 150 and the buffer 130 along the extending direction of the outer tube 110. The limiting member 170 is disposed between the two ends of the wire 160. When a pulling force acts on the other end of the wire 160, the limiting member 170 can abut against the buffer 130.

[0037] It can be understood that the setting of the flocked helical spring 150 can eliminate noise and abnormal noise during the compression and / or stretching process of the flocked helical spring 150.

[0038] It can be understood that the setting of the buffer 130 can prevent the limiting member 170 from directly hitting the connector 120 to generate noise and abnormal noise when the wire 160 is stretched to the limit position.

[0039] Optionally, the material of the limiting member 170 can be zinc alloy. The material of the buffer 130 can be nitrile rubber, so that the buffer 130 can withstand a large external force.

[0040] Further, the plug 140 has a positioning post 141. The balance limiting device 100 further includes a positioning ring 180. The positioning ring 180 is sleeved on the positioning post 141. One end of the flocked helical spring 150 is connected to the positioning ring 180.

[0041] It can be understood that the setting of the flocked helical spring 150 connected between the positioning ring 180 and the buffer 130 can prevent the two ends of the flocked helical spring 150 from rubbing against the plug 140 and the connector 120 respectively to generate noise and abnormal noise.

[0042] Optionally, the material of the plug 140 can be zinc alloy. The material of the positioning ring 180 can be polyhexamethylene adipamide, so that the positioning ring 180 has wear-resistant and self-lubricating properties, thereby avoiding noise and abnormal noise generated by friction between the positioning ring 180 and the plug 140.

[0043] Further, the limiting member 170 has a spindle shape, so that when the limiting member 170 moves in the outer tube 110 along with the telescopic movement of the pull wire 160, the friction with the air is reduced, thereby avoiding the generation of noise and abnormal noise. One end of the limiting member 170 facing the buffer member 130 is flattened to protect the buffer member 130 and achieve a better buffering effect.

[0044] Further, the balance limiting device 100 further includes a soft rubber sheath 190. The soft rubber sheath 190 is sleeved on the outer tube 110 to protect the outer tube 110 and prevent the outer tube 110 from directly colliding with the external structure when it shakes, thereby generating noise and abnormal noise.

[0045] Please refer to Figures 1 - 8 , Figure 5 which is a schematic structural diagram of the connector provided by the embodiment of the present application, Figure 6 is Figure 5 the right view of the connector, Figure 7 is Figure 6 the sectional view of the connector at B-B, Figure 8 which is a sectional view of the buffer member provided by the embodiment of the present application. The connector 120 may include, but is not limited to, a mounting body 121 and a pressing column 122. The pressing column 122 is connected to the mounting body 121. The pressing column 122 is press-fitted to one end of the outer tube 110 having an opening 111. A plurality of first annular grooves 1221 are provided on the circumferential side of the pressing column 122.

[0046] Further, the buffer member 130 may include, but is not limited to, a column body 131 and a first through hole 1311. The first through hole 1311 penetrates the column body 131. A second annular groove 132 is formed on the circumferential side of one end of the column body 131. The second annular groove 132 is an annular groove with an inner edge. A third annular groove 1222 is provided at one end of the pressing column 122. The third annular groove 1222 is an annular groove with a high and low edge. The connector 120 is provided with a second through hole 1223 penetrating the pressing column 122. The column body 131 is inserted into the second through hole 1223. The pull wire 160 passes through the first through hole 1311 and the second through hole 1223. The inner edge of the second annular groove 132 is elastically deformed and clamped in the third annular groove 1222, so that the buffer member 130 is fixed to the connector 120.

[0047] Optionally, the gap between the pressing column 122 and the buffer member 130 is less than or equal to 1 mm, so that particles with a larger diameter cannot enter the gap, which is beneficial to avoiding the generation of noise and abnormal noise.

[0049] It can be understood that the setting of the lubricating layer 162 enables the wire rope 160 to reduce or even eliminate the noise and abnormal noise generated by friction when it rubs against the channel 123 and the outlet 124.

[0050] Optionally, the material of the strength body 161 is carbon structural steel to ensure the tensile strength of the wire rope 160. The material of the lubricating layer 162 is nylon, enabling the wire rope 160 to have good anti-wear and self-lubricating properties.
