[0032] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the following through the drawing and example, the utility model is as a further description of the utility model detailed description. But it should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.
[0033] Reference Figures 1-6 A charging pile with telescopic charging socket, comprising a crossbar 1 and a telescopic mechanism 2, the telescopic mechanism 2 is fixedly installed on the crossbar 1.
[0034] The telescopic mechanism 2 comprises a telescopic motor 21, a transmission screw rod 22, a screw rod nut 23, a telescopic box body 24 and a scissor assembly 25, the telescopic motor 21 is fixedly installed on the crossbar 1, the output end of the telescopic motor 21 is connected with the transmission screw rod 22, the transmission screw rod 22 is installed with the screw rod nut 23, the screw rod nut 23 is connected with the scissor assembly 25, the axle pin head 253 of the scissor assembly 25 is connected on the inner wall of the telescopic box body 24, a plurality of charging sockets 3 are installed on the outer panel of the telescopic box body 24. The shaft coupling 26 is installed between the telescopic motor 21 and the transmission screw rod 22. When the extension movement is carried out, the charging socket 3 on the outer wall of the telescopic box body 24 can be exposed, which is convenient for more users to charge. The telescopic mechanism 2 is installed on the crossbar 1, and the crossbar 1 is installed on the parking shed 4 or the wall. The crossbar 1 is a hollow structure, and the inside is used for walking power cable. The installation height of the crossbar 1 is higher than that of the traditional charging pile crossbar, so as to avoid touching the electric vehicle during the extension process of the telescopic device.
[0035] The charging pile has the above structural design and exhibits significant advantages in actual use. When the extension movement is carried out, a plurality of charging sockets 3 can be additionally exposed. Compared with the traditional fixed charging pile, the number of vehicles that can be charged simultaneously in a unit area is greatly increased, and the space utilization rate of the charging facility is greatly improved. Because the charging socket 3 can be flexibly telescoped, the user can easily access without moving other vehicles during charging, and the operation time is shortened by an average of 2-5 minutes, effectively improving the convenience of user charging. At the same time, because the charging socket 3 is exposed and the cable is placed randomly, the risk of socket damage and the probability of tripping and crushing the cable are reduced, and the safety is significantly improved.
[0036] As a further illustration of the present embodiment, the telescopic box body 24 comprises n box sleeves 241 of different cross-sectional sizes, which are sequentially nested together. The outermost box sleeve 241 to the innermost box sleeve 241 are sequentially counted as the first box sleeve 241, the second box sleeve 241, the third box sleeve 241, and the nth box sleeve 241. Specifically, the box sleeves adopt a stepped nested structure, and a guide sliding groove and a sealing rubber strip are arranged between adjacent box sleeves. The sliding groove depth is greater than or equal to 3 times the wall thickness of the box sleeve, which ensures smooth sliding between the box sleeves, and at the same time, the sliding fit tolerance is strictly controlled within ±0.05 mm, effectively improving the telescopic stability. The sealing rubber strip is made of silicon rubber material with strong weather resistance, which ensures good waterproof and dustproof performance.
[0037] As a further illustration of the present embodiment, the charging socket 3 is installed on the outer panel of the box sleeve 241. The charging socket 3 can be installed on each panel of the box sleeve 241 as needed, such as the charging socket 3 being installed on each of the five outer panels of the first box sleeve 241. The socket panel is flush with the surface of the box sleeve through embedded installation, which ensures aesthetics and is not easily damaged by external forces. The charging socket 3 can be installed on the four outer panels of the second box sleeve 241, the third box sleeve 241, and the nth box sleeve 241, and the installation method is the same as that of the first box sleeve.
[0038] Through the above box sleeve structure and charging socket layout design, the charging pile exhibits significant advantages in actual use. Compared with traditional fixed charging piles, the use of multiple nested box sleeves and the reasonable distribution of charging sockets increases the number of charging interfaces, which can provide charging services for more electric vehicles in the same installation space, greatly improving the space utilization. In addition, due to the telescopic design of the box sleeve, when there are fewer charging vehicles, the telescopic box body can be retracted to reduce the occupation of public space; when there are more vehicles, the box body is expanded to quickly increase the charging interface, effectively improving the charging efficiency and meeting the charging demand at different times. At the same time, the good sealing and guide structure between the box sleeves enhances the stability and durability of the charging pile, reducing maintenance costs.
[0039] As a further illustration of the present embodiment, the scissor assembly 25 comprises a plurality of connecting rods 251 and a plurality of shaft pins 252. The shaft pins 252 are vertically arranged, and the upper and lower ends of the shaft pins 252 are connected to the connecting rods 251 in a hinged manner with a gap fit precision of H7 / g6. The connecting rods 251 and the shaft pins 252 form a four-bar linkage scissor mechanism. The shaft pins 252 can be divided into long shaft pins 2521 and short shaft pins 2522. The long shaft pins 2521 are installed at the center pivot position, and the upper and lower ends of the long shaft pins 2521 are both installed with the connecting rods 251. The adjacent connecting rods 251 are connected through the short shaft pins 2522.
[0040] As a further illustration of the embodiment, the shaft pin 252 at the head is provided with a shaft pin head 253 connected to the inner wall of the first box sleeve 241. Specifically, the shaft pin head 253 is firmly connected to the inner wall of the first box sleeve 241 by welding. The shaft pin head 253 is integrally formed with the shaft pin 252 and is made of high-strength alloy steel to ensure the connection strength. In actual application, only the head of the scissor assembly 25 is stably connected to the first box sleeve 241 by this connection mode, and the telescopic mechanism 2 can stably drive the box sleeve 241 to smoothly perform the telescopic movement when the telescopic mechanism 2 is driven.
[0041] Working principle:
[0042] The output shaft of the telescopic motor 21 is connected to the transmission screw rod 22 through the shaft coupling 26, and the transmission screw rod 22 penetrates the screw nut 23. The screw nut 23 is fixed to the central shaft position of the two connecting rods 251 by means of the upper and lower short shaft pins 2522. The connecting rods 251 are hinged by the short shaft pins 2522 and the long shaft pins 2521, thereby forming a scissor structure. The shaft pin head 253 is connected to the inner wall of the first box sleeve 241.
[0043] When the telescopic motor 21 is started, the output shaft starts to rotate, thereby driving the transmission screw rod 22 to rotate synchronously. Due to the cooperation between the screw nut 23 and the transmission screw rod 22, the rotary motion of the transmission screw rod 22 is converted into the linear motion of the screw nut 23, so that the screw nut 23 moves forward and backward on the transmission screw rod 22. The movement of the screw nut 23 drives the multi-stage connecting rods 251 connected thereto to perform the telescopic action. Because the shaft pin head 253 on the long shaft pin 2521 is connected to the first box sleeve 241, the telescopic movement of the connecting rods 251 drives the first box sleeve 241 to move.
[0044] Because the first to nth box sleeves 241 increase in size in sequence, and each box sleeve 241 is nested inside the previous box sleeve 241, a stepped nested structure is formed. When the first box sleeve 241 moves, it will in turn drive the subsequent second box sleeve 241, third box sleeve 241, …, and nth box sleeve 241 to perform the telescopic movement, so as to realize the expansion and contraction of the entire telescopic box body 24 to meet different charging needs.
[0045] The above is only a specific embodiment of the present application, but the technical features of the present application are not limited thereto. Any simple change, equivalent replacement or modification made on the basis of the present application to solve basically the same technical problem and achieve basically the same technical effect is covered by the protection scope of the present application.
