Description

Technical Field

[0001] The utility model belongs to the technical field of charging, and in particular relates to a flexible charging connector mechanism for an electric vehicle charging station. Background Art

[0002] Shared transportation is the sum of various smart travel modes that integrate social idle vehicles, car space or driving skills and other transportation resources under the background of sharing economy, relying on the Internet platform, and efficiently matching travel supply and demand through big data calculation to achieve shared travel capabilities. There are many modes of shared transportation, such as platform-based shared transportation, bicycle sharing, short-distance travel sharing, long-distance travel sharing and electric car sharing.

[0003] At present, shared charging vehicles require manual insertion of batteries. Users do not park at designated locations, which undoubtedly greatly increases labor costs and the difficulty of battery replacement. Users charge directly by plugging in. Most plugging methods are rigid connections. Excessive force during plugging can easily cause damage to the charging station. There is no buffering function, and an adjustable structure is used during the plugging process. During plugging, the plug connector is easily displaced, resulting in difficulty in insertion and inconvenience in use. Utility Model Content

[0008] The connector assembly is used to be plugged into the charging compartment for charging. The connector assembly is divided into a plug-in end and a fixed end. The plug-in end is used to plug and cooperate with the charging compartment, and the fixed end is used to fix to the electric vehicle.

[0009] In a preferred embodiment, an inner column is provided on the inner wall of the plug end, a mounting plate is bolted on the upper part of the inner column, a shaft cylinder is provided on the upper part of the mounting plate, and a conductive groove is fixed on the bottom of the plug end.

[0010] In a preferred embodiment, a positioning shaft is installed inside the fixed end, wherein a nut is installed below the positioning shaft through the mounting plate, a sleeve is sleeved around the periphery of the positioning shaft, and a spring is sleeved around the periphery of the positioning shaft to act between the sleeve and the mounting plate. The use of the spring can keep the positioning shaft lifted up, and when the plug-in end is plugged into the charging compartment, an impact force will be generated. At this time, the fixed end will be slightly displaced downward under the action of the spring, thereby buffering and reducing the force generated during plugging.

[0011] In a preferred embodiment, a flat square cutout is provided at the bottom of the positioning shaft, a flat square groove is provided on the mounting plate to limit the flat square cutout, a semicircular head is provided at the head of the positioning shaft, and a semicircular groove is provided inside the fixed end to cooperate with the semicircular head, so that the maximum downward movement distance of the positioning shaft is limited by the semicircular head within the semicircular groove.

[0012] In a preferred embodiment, the semicircular head has symmetrical and detachable limit bolts installed on both sides, and the semicircular groove is provided with a stabilizing groove and the limit bolt to limit each other. The cooperation between the limit bolt and the stabilizing groove allows the fixed end and the positioning shaft to remain integrated without deviation, and the cooperation between the flat square groove and the flat square cutout can greatly improve the stability of the positioning shaft and the fixed end.

[0013] In a preferred embodiment, the outer wall of the plug end is symmetrically provided with side blocks that are inclined and reduced from top to bottom and cooperate with the slideway, and the outer wall of the plug end is also provided with a raised platform that cooperates with the limit groove.

[0014] In a preferred embodiment, the top of the fixed end is symmetrically provided with extension blocks. The distance formed between the extension blocks is fixed by nuts in a shape that matches the head of the electric vehicle, so that the joint assembly can be fixed on the electric vehicle.

[0015] The technical solution of the utility model has the following beneficial effects:

[0016] 1. The unique positioning of the side block and the slide can make it easier for users to align and plug it into the charging bin. It can also help stabilize the plug-in end inside the charging bin and prevent the problem of displacement inside the charging bin. The setting of the side block tilting from top to bottom can make the plug-in process between the plug-in end and the charging bin smoother.

[0017] 2. The cooperation between the limit bolt and the stabilizing groove makes the fixed end and the positioning shaft remain integrated without deviation. The cooperation between the flat square groove and the flat square cut can greatly improve the stability of the positioning shaft and the fixed end, so that the fixed end always maintains a horizontal position with the plug-in end, and ensures that the plug-in end will not deflect during the displacement process of plugging, so as to avoid affecting the plug-in charging. This device can stabilize the position of the plug-in end while maintaining a certain degree of flexibility, so that the plug-in charging is smooth and there will be no jamming.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] refer to Figure 1 and Figure 2 , a flexible charging connector mechanism for an electric vehicle charging station, comprising;

[0032] A charging component, wherein the charging component comprises a charging seat 10, wherein a charging compartment 11 is provided inside the charging seat 10, and the charging seat 10 is fixed in a charging base station, and the charging base station directly supplies power to the charging seat 10;

[0033] refer to Figure 1 and Figure 3 , the connector assembly is used to be plugged into the charging compartment 11 for charging. The connector assembly is divided into a plug-in end 15 and a fixed end 16. The plug-in end 15 is used to plug and match with the charging compartment 11, and the fixed end 16 is used to fix with the electric vehicle. The top of the fixed end 16 is symmetrically provided with extension blocks 33, and there is a distance between the extension blocks 33. The distance formed between the extension blocks 33 is stuck in a shape that matches it and is fixed by a nut. The matching shape is the head of the electric vehicle, so that the connector assembly will be fixed on the electric vehicle. The bottom of the charging compartment 11 is provided with a conductive sheet 14, and the bottom of the plug-in end 15 is fixed with a conductive groove 19.

[0034] In the above scheme, when the electric vehicle needs to be charged, the mobile electric vehicle will plug the plug-in terminal 15 into the charging compartment 11. After the plug-in is completed, the conductive groove 19 and the conductive sheet 14 correspond to each other to start power supply. Furthermore, the inner wall of the charging compartment 11 is symmetrically provided with a slideway 12, and the inner wall of the charging compartment 11 is also symmetrically provided with a limit groove 13. The outer wall of the plug-in terminal 15 is symmetrically provided with side blocks 17 that are inclined and reduced from top to bottom and cooperate with the slideway 12. The unique positioning of the side blocks 17 and the slideway 12 can make it more convenient for the user to align and plug in the charging compartment 11. At the same time, it can also help the plug-in terminal 15 to stabilize in the charging compartment 11 and prevent the problem of displacement in the charging compartment 11. The setting of the side blocks 17 that are inclined and reduced from top to bottom can make the plug-in process of the plug-in terminal 15 and the charging compartment 11 smoother.

[0035] Furthermore, the outer wall of the plug-in terminal 15 is also provided with a protruding platform 18 which cooperates with the limiting groove 13. The combination of the protruding platform 18 and the limiting groove 13 provides the maximum plug-in distance of the plug-in terminal 15, while further improving the stability of the plug-in terminal 15, and improving the electrical connection effect between the conductive groove 19 and the conductive sheet 14, so that the charging is stable and efficient.

[0036] refer to Figure 4-Figure 8 An inner column 20 is provided on the inner wall of the plug-in end 15, a mounting plate 21 is bolted on the upper part of the inner column 20, a shaft cylinder 22 is provided on the upper part of the mounting plate 21, a positioning shaft 25 is installed inside the fixed end 16, a nut 24 is installed below the positioning shaft 25 passing through the mounting plate 21, a sleeve 29 is sleeved on the outer periphery of the positioning shaft 25, and a spring 30 is also sleeved on the outer periphery of the positioning shaft 25 to act between the sleeve 29 and the mounting plate 21.

[0037] In the above scheme, the assembly between the plug-in end 15 and the fixed end 16 is as follows: first, the sleeve 29 is inserted into the outer periphery of the positioning shaft 25, and then the spring 30 is inserted, and the nut 24 is installed at the bottom of the mounting plate 21 below the positioning shaft 25. Then, the mounting plate 21 is bolted to the top of the inner column 20, and finally fixed to the electric vehicle head through the extension block 33. The use of the spring 30 can keep the positioning shaft 25 lifted up. When the plug-in end 15 is plugged into the charging compartment 11, an impact force will be generated. At this time, the fixed end 16 will be slightly displaced downward under the action of the spring 30, thereby buffering and reducing the force generated during plugging, effectively protecting the charging seat 10, and effectively improving the flexibility of the joint assembly under the action of the spring 30. At the same time, the service life of the plug-in end 15 and the fixed end 16 is also improved. There is a baffle 34 bolted to the fixed end 16 above the fixed end 16, which is used to seal one end of the fixed end 16 to prevent dust from entering the fixed end 16.

[0038] Further references Figure 4 , Figure 6 and Figure 7 A flat square cutout 26 is provided at the bottom of the positioning shaft 25, and a flat square groove 23 is provided on the mounting plate 21 to limit the flat square cutout 26. The cooperation between the flat square groove 23 and the flat square cutout 26 can prevent the positioning shaft 25 from rotating; a semicircular head 27 is provided at the head of the positioning shaft 25, and a semicircular groove 31 is provided inside the fixed end 16 to cooperate with the semicircular head 27, so that the maximum downward movement distance of the positioning shaft 25 is limited by the semicircular head 27 within the semicircular groove 31;

[0039] The limiting bolts 28 are symmetrically and detachably installed on both sides of the semicircular head 27. A stabilizing groove 32 is provided in the semicircular groove 31 to limit the limiting bolt 28 to each other. With the cooperation of the limiting bolt 28 and the stabilizing groove 32, the fixed end 16 and the positioning shaft 25 are kept as one without deviation. The cooperation of the flat square groove 23 and the flat square cutout 26 can greatly improve the stability of the positioning shaft 25 and the fixed end 16, so that the fixed end 16 always maintains a horizontal position with the plug-in end 15, and ensures that the plug-in end 15 will not deflect when the plug-in produces displacement, so as to avoid affecting the plug-in charging. The device can stabilize the position of the plug-in end 15 while maintaining a certain degree of flexibility, so that the plug-in charging is smooth and there will be no jamming.

[0040] It is worth noting that the maximum displacement distance of the plug-in end 15 will not cause the flat square groove 23 and the flat square cutout 26 to be separated from each other. During installation, the installation position of the nut 24 is adjusted to control the maximum displacement distance of the positioning shaft 25.

[0041] The specific implementation process of this embodiment is as follows:

[0042] When charging the electric vehicle, the mobile electric vehicle inserts the plug-in terminal 15 into the charging compartment 11. After the plug-in is completed, the conductive groove 19 and the conductive sheet 14 correspond to each other to start power supply. The unique positioning of the side block 17 and the slide 12 can make it more convenient for the user to align and plug in the charging compartment 11. At the same time, it can also help the plug-in terminal 15 to be stable in the charging compartment 11 to prevent the problem of displacement in the charging compartment 11.

[0043] The use of the spring 30 can keep the positioning shaft 25 lifted up. When the plug-in end 15 is plugged into the charging compartment 11, an impact force will be generated. At this time, the fixed end 16 will be slightly displaced downward under the action of the spring 30, thereby buffering and reducing the force generated during plugging to protect the charging base 10.

The protection scope of the present invention is defined by the claims. Various modifications or equivalent substitutions may be made to the present invention within the essence and protection scope of the present invention.
