All directional indications in the embodiments of this application (such as up, down, left, right, front, back...) are only used to explain the relative positional relationship, movement, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications also change accordingly. In addition, the terms "including" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products, or devices.

[0043] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] The balance limiter provided in the present application includes: a shell, provided with a accommodating cavity and a first opening connected to the accommodating cavity; an elastic member, arranged in the accommodating cavity; a pull rope assembly, part of which is arranged in the accommodating cavity, one end of the pull rope assembly abuts against the elastic member, and the other end of the pull rope assembly passes through the first opening; a first connecting member, part of which passes through the first opening and blocks the accommodating cavity, the first connecting member is provided with a channel connected to the accommodating cavity, the channel passes through the first connecting member, and the other end of the pull rope assembly passes through the channel; a second connecting member, connected to the other end of the pull rope assembly; wherein the first connecting member is used to connect one of the moving member and the fixed member, and the second connecting member is used to connect the moving member and the other of the fixed member. In this way, the balance limiter can assist the moving member in moving closer to the fixed member and can counterbalance the movement of the moving member away from the fixed member.

[0045] Please refer to Figures 1 to 7The balancing limiter 100 may include but is not limited to a housing 110, an elastic member 120, a pull rope assembly 130, a first connecting member 140, and a second connecting member 150. The housing 110 is provided with a housing chamber 111 and a first opening 112. The first opening 112 is in communication with the housing chamber 111. The elastic member 120 is disposed in the housing chamber 111. Part of the structure of the pull rope assembly 130 is disposed in the housing chamber 111. One end of the pull rope assembly 130 abuts against the elastic member 120. The other end of the pull rope assembly 130 passes through the first opening 112. Part of the structure of the first connecting member 140 passes through the first opening 112 and is blocked in the housing chamber 111. The first connecting member 140 is provided with a channel 146 in communication with the housing chamber 111. The channel 146 passes through the first connecting member 140. The other end of the pull rope assembly 130 passes through the channel 146. The second connecting member 150 is connected to the other end of the pull rope assembly 130. Among them, the first connecting member 140 is used to connect one of the moving member and the fixed member. The second connecting assembly 150 is used to connect the moving member and the other of the fixed member. In this way, when the moving member moves away from the fixed member under the action of the driving force, one end of the pull rope assembly 130 compresses the elastic member 120, and under the action of the restoring force of the elastic member 120, a balancing force is generated to limit the movement of the moving member away from the fixed member, thereby making the moving member more stable in the process of moving away from the fixed member. When the moving member moves closer to the fixed member under the action of the driving force, the pull rope assembly 130 is partially retracted into the accommodating cavity 111 of the shell 110 under the action of the restoring force of the elastic member 120, and at the same time, the restoring force of the elastic member 120 can help the moving member move closer to the fixed member. In particular, please refer to Figures 17 to 19 In the floor door system 1000 of vehicle 2000, the floor door 300 is hinged to the rear end 400, and a balancing stopper 100 is connected between the floor door 300 and the rear end 400. When the floor door 300 rotates between an open and closed position, the balancing stopper 100 not only constrains the floor door 300 from rotating away from the rear end 400, making the opening process smoother, but also assists the floor door 300 in rotating toward the rear end 400, thereby preventing insufficient closing force. This is particularly true when the floor door 300 is heavy, as the gravitational force component of the floor door 300 is greater, making insufficient closing force more likely to occur. When the floor door 300 is hovering at any position between the open and closed positions, the balancing stopper 100 can also provide a force to keep the floor door 300 in a suspended position. When the floor door 300 is closed and the vehicle 2000 is traveling uphill, for example, the balancing stopper 100 can also provide a force to keep the floor door 300 closed.

[0046] Furthermore, the elastic member 120 can be a coil spring. One end of the elastic member 120 abuts against the first connecting member 140. The shell 110 is tubular, so that the outer wall of the shell 110 is easy to be embraced and clamped, and the inner wall can provide guidance for the elastic member 120. A second opening 113 is provided at one end of the shell 110 away from the first opening 112. The balance limiter 100 also includes a plug 170. At least part of the structure of the plug 170 passes through the second opening 113 and blocks the accommodating cavity 111. In the initial state, the elastic member 120 is in a pre-stressed state so that one end of the pull rope assembly 130 is clamped between the other end of the elastic member 120 and the plug 170. The other end of the pull rope assembly 130 passes through the interior of the elastic member 120. The setting of the pre-stressed state of the elastic member 120 prevents loosening inside the shell 110 and avoids the pull rope assembly 130 compressing the free travel of the elastic member 120. The second opening 113 and the plug 170 are provided so that the preload of the elastic member 120 can be adjusted to meet the use requirements by adjusting the amount of ingress blocked by the plug 170 or replacing plugs 170 with different lengths of blocked ingress. The initial state refers to the state when the pull cord assembly 130 is not stretched.

[0047] In some embodiments, the plug 170 may be screwed to the inner wall of the housing 110 , and the preload of the elastic member 120 may be adjusted by adjusting the screwing process of the plug 170 .

[0048] Please refer to Figures 1 to 8 The pull cord assembly 130 may include but is not limited to a pull cord 131, a contact member 132, and a limit member 133. The contact member 132 is fixed to one end of the pull cord 131 and contacts the elastic member 120. The contact surface of the contact member 132 is circular and has a diameter greater than the outer diameter of the elastic member 120, so as to fully contact the elastic member 120. The limit member 133 is fixed between the two ends of the pull cord 131. In the ultimate tensile state, the limit member 133 contacts the first connecting member 140 to limit the range of movement of the moving member away from the fixed member. In particular, please refer to Figures 17 to 19 In the floor door system 1000 of vehicle 2000, the opening angle of the floor door 300 relative to the rear end 400 is limited to prevent excessive opening. The distance between the stopper 133 and the first connector 140 can be set according to actual needs. The pull cord 131 is flexible and can be threaded through the channel 146 of the first connector 140. The internal force generated by the flexible pull cord 131 also helps maintain stability when the moving part moves away from the fixed part and maintains strength when the moving part moves toward the fixed part.

[0049] Optionally, the pull rope 131 may be made of stainless steel, specifically 304 stainless steel.

[0050] Please refer to Figures 1 to 10The first connector 140 may include, but is not limited to, a main body 141, a blocking portion 142, a first mounting portion 143, and an outlet portion 144. The blocking portion 142 is connected to one end of the main body 141. At least a portion of the blocking portion 142 passes through the first opening 112 and blocks the accommodating cavity 111. The first mounting portion 143 is connected to the other end of the main body 141. The first mounting portion 143 is used to connect one of the moving part and the fixed part. The outlet portion 144 is disposed on the side of the first mounting portion 143 facing away from the main body 141. The outlet portion 144 is provided with a trumpet-shaped outlet 1441 that communicates with a channel 146 to guide the pull cord assembly 130 and reduce wear on the pull cord assembly 130 during extension and retraction. The channel 146 extends through the blocking portion 142, the main body 141, and the first mounting portion 143. The channel 146 has a smooth curved shape to guide the pull cord assembly 130 and reduce wear on the pull cord assembly 130 during extension and retraction. The other end of the pull rope assembly 130 passes through the trumpet-shaped outlet 1441 .

[0051] Furthermore, the first connecting member 140 also includes a second mounting portion 145. The second mounting portion 145 cooperates with the first mounting portion 143 to connect one of the moving member and the fixed member. The second mounting portion 145 may include but is not limited to an extension structure 1451 and a fixed structure 1452. The extension structure 1451 is connected between the main body 141 and the fixed structure 1452. The fixed structure 1452 is provided with a first mounting hole 1452a. The first mounting portion 143 is provided with a second mounting hole 1431 and a third mounting hole 1432. The connecting lines between the first mounting hole 1452a, the second mounting hole 1431 and the third mounting hole 1432 form a triangle, so that the connection between the first connecting member 140 and one of the moving member and the fixed member is more firm and reliable.

[0052] Furthermore, the blocking portion 142 may include, but is not limited to, a first limiting structure 1421 and a blocking structure 1422 connected to one side of the first limiting structure 1421. The blocking structure 1422 passes through the first opening 112 and blocks the accommodating cavity 111. One end of the housing 110 having the first opening 112 abuts against the first limiting structure 1421.

[0053] Furthermore, a plurality of annular protrusions 1422a are provided around the periphery of the blocking structure 1422. These annular protrusions 1422a abut against the inner wall of the housing 110, ensuring a more complete contact between the blocking structure 1422 and the inner wall of the housing 110 and facilitating subsequent fusion connection. A stepped hole 1422b is provided on the end surface of the blocking structure 1422 facing the elastic member 120.

[0054] Optionally, the first connecting member 140 may be integrally formed.

[0055] Optionally, the first connecting member 140 may be made of aluminum alloy.

[0056] Please refer to Figures 1 to 12 The balance limiter 100 also includes a buffer member 160 clamped on the first connecting member 140. The buffer member 160 is clamped and connected to the blocking structure 1422. The buffer member 160 is accommodated in the accommodating cavity 111 and is arranged near the first opening 112. In the tensile limit state, the limit member 133 abuts against the buffer member 160. The buffer member 160 is provided with a through hole 164 connecting the accommodating cavity 111 and the channel 146. The other end of the pull rope assembly 130 passes through the through hole 164. The provision of the buffer member 160 plays a role in protection and reducing vibration and noise.

[0057] Furthermore, the buffer member 160 may include but is not limited to a clamping cap 161, a second limiting structure 163, and a connecting shaft 162 connected between the clamping cap 161 and the second limiting structure 163. The clamping cap 161 passes through the small hole of the stepped hole 1422b, enters the large hole of the stepped hole 1422b, and is clamped at the step connected to the stepped hole 1422b. The connecting shaft 162 is provided through the small hole of the stepped hole 1422b. The second limiting structure 163 abuts against the end face of the blocking structure 1422 facing the elastic member 120. The through hole 164 passes through the second limiting structure 163, the connecting shaft 162, and the clamping cap 161. The through hole 164 and the stepped hole 1422b constitute part of the channel 146.

[0058] Please refer to Figures 1 to 16 The second connecting assembly 150 may include but is not limited to a ball stud 151, a clip 153, and a ball and socket clamp 152. The ball stud 151 is rotatably connected to the ball and socket clamp 152. The clip 153 is passed through the ball and socket clamp 152 to limit the ball stud 151.

[0059] Furthermore, ball stud 151 may include, but is not limited to, a connected ball head portion 1511 and a bolt portion 1512. Ball and socket clamp 152 may include, but is not limited to, a connected ball socket portion 1521 and a clamp portion 1522. Ball head 1511 is disposed within socket portion 1521, allowing ball stud 151 and ball and socket clamp 152 to be rotatably connected. Clamp portion 1522 is connected to the other end of cable assembly 130. Bolt portion 1512 is used to connect the other of the moving component and the fixed component.

[0060] Furthermore, the socket portion 1521 is provided with two opposing cutouts 1521a. The clip 153 surrounds the outer periphery of the socket portion 1521, with both ends passing through the cutouts 1521a to retain the ball head 1511 within the socket portion 1521. A retaining groove 1521b is provided on the outer periphery of the socket portion 1521 between the two cutouts 1521a. The portion of the clip 153 between its two ends is disposed within the retaining groove 1521b to maintain its position on the outer periphery of the socket portion 1521.
