[0024] Please refer to Figures 1 to 3The embodiment of the present application provides a charging pile gun wire clamping device 10. The charging pile gun wire clamping device 10 comprises a gear-rack engagement mechanism 100 and a connecting rod mechanism 200. The gear-rack engagement mechanism 100 is used to drive the connecting rod mechanism 200 to move, so as to tighten or loosen the gun wire of the charging gun. The gear-rack engagement mechanism 100 comprises a driving member 110, a gear 120, a rack 130 and a first mounting cover 140. The gear 120 is coaxially fixedly connected with the driving member 110. The rack 130 is assembled on the first mounting cover 140. The rack 130 is movably connected with the gear 120 and the connecting rod mechanism 200 respectively. The driving member 110 controls the rack 130 to move up and down through the gear 120, and the rack 130 drives the connecting rod mechanism 200 to move, so as to tighten or loosen the gun wire of the charging gun.

[0025] In some embodiments, the structure of the driving member 110 is not limited, as long as the gear 120 can be controlled to rotate. Specifically, the driving member 110 can be a step motor. The gear 120 is coaxially fixedly connected with the output shaft of the driving member 110 through a tight screw or a key groove.

[0026] In some embodiments, the first mounting cover 140 serves as a support and guide base, and a precise linear sliding groove is processed on the first mounting cover 140. The rack 130 is embedded in the sliding groove and can smoothly slide along the length direction of the sliding groove. Meanwhile, the toothed surface of the rack 130 is engaged with the gear 120. In some embodiments, the rack 130 is a symmetrical rack.

[0027] In some embodiments, the rack 130 is slidably arranged in the sliding groove of the first mounting cover 140, and a continuous straight tooth portion is arranged on one side of the rack 130. The straight tooth portion is engaged with the gear teeth of the gear 120 to form a gear-rack transmission pair. The rack 130 is movably connected with the input end of the connecting rod mechanism 200 through a first hinged shaft. When the rack 130 linearly reciprocates under the driving of the gear 120, the displacement and force of the rack 130 can be transmitted to the connecting rod mechanism 200 through the hinged point, so that the connecting rod mechanism 200 is driven to move.

[0028] In some embodiments, the connecting rod mechanism 200 serves as a clamping execution unit. When the driving member 110 controls the rack 130 to move up and down through the gear 120, a certain displacement is generated, so that the rack 130 drives the connecting rod mechanism 200 to move, thereby tightening or loosening the gun wire of the charging gun. In this way, the gun wire of the charging gun with different wire diameters can be processed and tightened or loosened, which is good in universality and can improve the assembly efficiency.

[0029] In some embodiments, the linkage mechanism 200 can be designed in a symmetrical manner as a clamping execution unit, including two sets of identical linkage assemblies which are mirror arranged with the longitudinal center line of the rack 130 as the axis of symmetry. Different wire diameter gun wire fastening can be achieved, and the use convenience, compatibility and assembly efficiency can be improved.

[0030] In some embodiments, the linkage mechanism 200 includes a first linkage assembly 210 and a second linkage assembly 220, which are symmetrically arranged on both sides of the rack 130. The first linkage assembly 210 and the second linkage assembly 220 are both movably connected with the rack 130, and the first linkage assembly 210 and the second linkage assembly 220 are structurally identical. On the one hand, the assembly efficiency is improved, and on the other hand, the structure is completely consistent, the compatibility is good, and the use convenience is improved.

[0031] In some embodiments, the first linkage assembly 210 and the rack 130 can be movably connected in any applicable mechanical connection form. For example, the first linkage assembly 210 can be movably connected with the rack 130 through a hinge shaft. Specifically, an axle hole can be arranged at the corresponding end of the rack 130, and a connecting hole is arranged at the input end of the first linkage assembly 210. The hinge shaft is arranged in the axle hole and the connecting hole, so as to realize the rotational pair connection between the rack 130 and the first linkage assembly 210. This connection mode can effectively convert the linear reciprocating motion of the rack 130 into the planar motion of the first linkage assembly 210, and allows the two to rotate relative to each other at the connection in a predetermined direction. Similarly, the second linkage assembly 220 and the rack 130 can also be movably connected in the above-mentioned manner, which will not be described here.

[0032] In some embodiments, the first linkage assembly 210 includes a first linkage 211 and a second linkage 212, which are movably connected. The first linkage 211 is movably connected with the rack 130.

[0033] In some embodiments, the first linkage 211 and the second linkage 212 can be movably connected in any applicable mechanical connection form. In some embodiments, the first linkage 211 and the second linkage 212 are connected through a pin 213. Through the rotation of the first linkage 211, the rotation of the second linkage 212 is driven, so that the first linkage assembly 210 generates contraction and expansion, which can meet the fastening of gun wires with different wire diameters in cooperation with the second linkage assembly 220.

[0034] In some embodiments, the first connecting rod 211 is provided with a first sliding slot, and the rack 130 is provided with a protrusion matched with the first sliding slot, when the rack 130 drives the first connecting rod assembly 210 to move, the protrusion slides in the first sliding slot. In some embodiments, the rack 130 and the first connecting rod 211 are movably connected through a sliding fit structure. Specifically, the first connecting rod 211 is formed with a first sliding slot; correspondingly, the rack 130 is provided with a protrusion matched with the first sliding slot, the protrusion is at least partially embedded in the first sliding slot and can slide in the first sliding slot. When the gear 120 drives the rack 130 to move linearly reciprocatingly, through the sliding fit of the protrusion and the first sliding slot, the linear movement of the rack 130 is converted into the compound movement of the first connecting rod 211, wherein the sliding of the protrusion along the first sliding slot adapts to the change of the angle and position of the first connecting rod 211 during the movement.

[0035] In some embodiments, when it is needed to clamp the gun wire, the driving member 110 (step motor) receives a control signal to rotate in a positive direction, driving the gear 120 to rotate. The gear 120 drives the rack 130 engaged therewith to move downward (or upward) along the sliding slot of the first mounting cover 140. The linear movement of the rack 130 pulls the first connecting rod assembly 210 and the second connecting rod assembly 220 articulated therewith to rotate inward around the respective articulation points with the rack 130 (the rotation of the first connecting rod 211 pushes the second connecting rod 212 through the bolt). The two groups of symmetrical connecting rod assemblies are collectively contracted inward, thereby clamping the gun wire 101 of the charging gun placed in the center of the mechanism from both sides. Due to the holding torque of the step motor, the mechanism can stably maintain the clamping state.

[0036] When it is needed to release the gun wire, the driving member 110 rotates reversely, driving the rack 130 to move in the opposite direction through the gear 120. The rack 130 pushes the two first connecting rods 211 to rotate outward, thereby pulling the second connecting rod 212 through the bolt 230, so that the whole connecting rod mechanism 200 expands outward, thereby releasing the clamped gun wire 101. In the embodiment, through the gear and rack engagement transmission mode, the displacement amount of the gun wire clamping mechanism is adjusted by controlling the transmission ratio of the gear, and the transmission precision is high.

[0037] In some embodiments, the first linkage assembly 210 further comprises a roller 214 fixed to an end of the second linkage 212 away from the first linkage 211. The roller 214 is fixedly arranged on the second linkage 212 away from the end connected with the first linkage 211. The central axis of the roller 214 is perpendicular to the extension direction of the second linkage 212 or forms a predetermined angle with the extension direction, so that the roller 214 can roll along a predetermined path or working surface under the driving of the second linkage 212. Such arrangement makes the swing or compound motion of the second linkage 212 finally converted into smooth rolling contact through the roller 214, which is beneficial to reduce friction and transmit specific motion trajectory.

[0038] In some embodiments, the gear-rack engagement mechanism 100 further comprises a second mounting cover 150 fixedly connected with the first mounting cover 140, and a cavity is formed between the first mounting cover 140 and the second mounting cover 150, and the rack 130 and the first linkage 211 are uniformly arranged in the cavity.

[0039] In some embodiments, the way in which the second mounting cover 150 is fixedly connected with the first mounting cover 140 is not limited, for example, the second mounting cover 150 and the first mounting cover 140 are fixedly connected with each other by fasteners, buckles or welding.

[0040] After the second mounting cover 150 is fixedly connected with the first mounting cover 140, a closed or semi-closed cavity can be formed between them. The rack 130 and at least a part of the first linkage assembly 210 (for example, the first linkage 211) are accommodated and arranged in the cavity. This structure not only provides stable installation and motion space for the rack 130 and the linkage mechanism, but also plays a role in protection, dust prevention and motion safety guarantee.

[0041] Please attend Figure 4Another embodiment of the present application provides a charging pile 20. The charging pile 20 comprises a pile body 21 and the charging pile gun wire clamping device 10 in any one of the above embodiments. The charging pile gun wire clamping device 10 comprises a gear rack engagement mechanism 100 and a connecting rod mechanism 200. The gear rack engagement mechanism 100 is used to drive the connecting rod mechanism 200 to move to tighten or loosen the gun wire of the charging gun. The gear rack engagement mechanism 100 comprises a driving member 110, a gear 120, a rack 130 and a first mounting cover 140. The gear 120 is coaxially fixedly connected with the driving member 110. The rack 130 is assembled in the first mounting cover 140. The rack 130 is movably connected with the gear 120 and the connecting rod mechanism 200 respectively. The driving member 110 controls the rack 130 to move up and down through the gear 120, and the rack 130 drives the connecting rod mechanism 200 to move to tighten or loosen the gun wire of the charging gun. In this embodiment, the gear rack engagement mechanism 100 cooperates with the connecting rod mechanism 200 to realize the processing and tightening or loosening of the gun wire 101 of the charging gun with different wire diameters, which not only has good universality, but also improves the assembly efficiency.
