Description

Technical Field

[0001] The utility model belongs to the field of three-dimensional charging equipment, and in particular relates to a main guide device of a plug-in component, a charging plug-in device and a three-dimensional charging station. Background Art

[0002] With the development of society, the number of new energy vehicles is gradually increasing, and new energy vehicles need to be charged in three-dimensional charging stations. In the existing technology, the prominent defect of three-dimensional charging stations is that when the vehicle carrier with electric vehicles enters the charging position of the three-dimensional charging station and plugs into the charging facility to draw power, the vehicle carrier with electric vehicles is mobile and generates vibration. In a vibrating environment, it is easy to cause inaccurate docking, which may damage the plug-in mechanism. Alternatively, in a vibrating environment, other plug-in mechanisms may produce loose connections, which in turn generates heat, reduces charging power, and prolongs charging time. This problem cannot be effectively solved, leaving safety hazards. Summary of the Invention

[0003] The purpose of the present utility model is to address the deficiencies of the existing technology and provide a charging plug device and a three-dimensional charging station using the charging plug device, which can realize automatic correction and centering of the plug components and close connection in an environment where the connection position of the charging device will vibrate when the vehicle is moving, thereby preventing the occurrence of false connections and ensuring charging safety.

[0004] The technical solutions adopted in this utility model are as follows.

[0005] A charging plug device for a three-dimensional charging station is characterized by comprising a charging plug device mounting assembly, two charging plug connectors, and at least two plug-in main docking guide assembly.

[0006] The charging plug device mounting assembly includes a first connecting vertical plate, a second connecting vertical plate, and a third connecting vertical plate, wherein the second connecting vertical plate is located between the first connecting vertical plate and the third connecting vertical plate; a plurality of support rod mounting through holes are provided on the first connecting vertical plate, wherein the central axis of each support rod mounting through hole is perpendicular to the side of the second connecting vertical plate away from the first connecting vertical plate, and each support rod is hingedly connected to a support rod mounting through hole at an end away from the second connecting vertical plate; each support rod is fixed to the second connecting vertical plate at an end away from the first connecting vertical plate; a spring is mounted on each support rod, wherein one end of the spring contacts the first connecting vertical plate and the other end contacts the second connecting vertical plate;

[0007] A charging connector is installed on the side of the second connecting vertical plate close to the third connecting vertical plate and the side of the third connecting vertical plate close to the second connecting vertical plate. Each plug-in main docking guide assembly includes a main guide rod and a main guide rod guide sleeve.

[0008] Each main guide rod is located on the second connecting plate and each main guide rod guide sleeve is located on the third connecting plate, or each main guide rod guide sleeve is located on the second connecting plate and each main guide rod is located on the third connecting plate. The main guide rods of each set of plug-in main docking guide components are inserted into the main guide rod guide sleeves, and the two charging connectors are docked and connected.

[0009] The beneficial effect of the present invention is that when the third connecting plate approaches the first connecting plate and each plug-in main connecting guide device is docked, the two charging docking assemblies can be docked. When the second connecting plate and the third connecting plate approach each other, each support rod is movable, and the blocking body can be used as a hinge point so that the end of each support rod away from the support rod installation through hole can move slightly in a straight line direction perpendicular to the second connecting plate, thereby facilitating docking; each support rod is provided with a spring, one end of the spring contacts the first connecting plate, and the other end contacts the second connecting plate. In this way, before docking, each support rod can be constrained to be in a horizontal state, which is convenient for accurate centering; at the same time, during docking, a clamping force is also applied to the second support plate. Accurate docking of each plug-in main connecting guide device can create a good docking environment for the charging docking assemblies arranged on the first connecting plate and the second connecting plate.

[0010] A support rod is inserted into each support rod installation through hole of the second connecting vertical plate, and a movable gap is provided between the portion where each support rod is inserted into the support rod installation through hole and the support rod installation through hole;

[0011] The diameter of the part of each support rod inserted into the support rod mounting hole is smaller than the diameter of the rest of the support rod, thereby forming a step on the support rod, and the support rod is provided with a side blocker at the end away from the second connecting vertical plate, and the distance between the step and the side blocker is greater than the thickness of the first connecting vertical plate, or, the support rod is provided with a side blocker at the end away from the second connecting vertical plate, and a middle blocker is provided on the side of the first connecting vertical plate on the support rod close to the second connecting vertical plate; the distance between the side blocker and the middle blocker is greater than the thickness of the first connecting vertical plate.

[0012] There is a movable gap between the part of each support rod inserted into the support rod mounting through hole and the support rod mounting through hole, so that the second connecting vertical plate is equivalent to a cantilever structure installed on the first connecting vertical plate, which can move slightly in a direction perpendicular to the second connecting vertical plate and away from the normal direction of the side of the first connecting vertical plate; each support rod is equipped with a spring, and when vibration occurs, the second vertical plate can move slightly. When each plug-in main connecting guide device is docked, the spring presses the second connecting vertical plate, and even if the second connecting vertical plate and the third connecting vertical plate are slightly misaligned, the charging docking components on the second connecting vertical plate and the third connecting vertical plate can be tightly docked.

[0013] As a preferred technical solution, each side blocking body or each middle blocking body is threadedly connected to the support rod.

[0014] As a preferred technical solution, each side blocker on the support rod is provided with a gasket on the side closest to the first connecting plate. The gasket facilitates adjustment of the distance between the side blocker and the second connecting plate, while also increasing the frictional resistance of the side blocker on the second connecting plate.

[0015] As a preferred technical solution, a first spring positioning groove is coaxially provided on the outside of each support rod mounting through-hole on the side of the first connecting vertical plate near the second connecting vertical plate, and a second spring positioning groove is coaxially provided on the outside of each support rod on the side of the second connecting vertical plate near the first connecting vertical plate. The two ends of each spring are respectively inserted into the first spring positioning groove closest to it and the second spring positioning groove closest to it. With this technical solution, when vibration occurs, when the second connecting vertical plate moves slightly in a direction perpendicular to the normal of the second connecting vertical plate away from the side of the first connecting vertical plate, the spring exerts a centripetal force on the second connecting vertical plate to return to its original position, automatically adjusting the second connecting vertical plate back to its initial position, which is conducive to centering.

[0016] As a preferred technical solution, each main guide rod is arranged on the side of the second connecting vertical plate close to the third connecting vertical plate, and the diameter of the main guide rod near the third connecting vertical plate gradually decreases along the direction close to the third connecting vertical plate to form a pointed head, and the third connecting vertical plate is provided with a plurality of guide sleeve mounting holes, and each main guide rod guide sleeve is installed on a guide sleeve mounting hole. Alternatively, each main guide rod is arranged on the side of the third connecting vertical plate close to the second connecting vertical plate, and the diameter of the main guide rod near the second connecting vertical plate gradually decreases along the direction close to the second connecting vertical plate to form a pointed head, and the second connecting vertical plate is provided with a plurality of guide sleeve mounting holes, and each main guide rod guide sleeve is installed on a guide sleeve mounting hole. Alternatively, each main guide rod is arranged on the side of the second connecting vertical plate close to the third connecting vertical plate, and the third connecting vertical plate is provided with a plurality of guide sleeve mounting holes, and each main guide rod guide sleeve is installed on a guide sleeve mounting hole, and each main guide rod guide sleeve is provided with a bell mouth near the end of the second connecting vertical plate.

[0017] With this technical solution, during docking, each guide plug can be inserted into its corresponding guide plug hole. The docking end of the main guide plug rod is provided with a pointed head and the docking end of the guide plug hole is provided with a bell mouth, leaving an adjustment margin, which can solve the problem that the main guide plug cannot be inserted into the guide plug hole when the position is slightly mismatched due to vibration; a spring is provided on each support rod, one end of the spring contacts the first connecting vertical plate, and the other end contacts the second connecting vertical plate. In this way, before docking, each support rod can be constrained to be in a horizontal state, which facilitates accurate docking; at the same time, during docking, a pressing force is also applied to the second support plate. This further creates a good docking environment for the charging docking components arranged on the first connecting vertical plate and the second connecting vertical plate. Its beneficial effects are: when docking, the second connecting vertical plate is equivalent to a cantilever structure installed on the first connecting vertical plate, which can move slightly in a direction perpendicular to the second connecting vertical plate and away from the normal line of the side surface of the first connecting vertical plate. When docking with the plug-in main connecting guide device, the position change of the charging docking assembly caused by vibration can be overcome to achieve accurate horizontal docking; after docking, under the action of the spring, the charging docking assembly is always tightly combined, and the connection position of the charging equipment is always closely close even in a vibration environment, which solves the problems of virtual connection in the existing technology, eliminates heat generation, reduces charging power, prolongs charging time, and has safety hazards.

[0076] Below, the utility model is further described with reference to the accompanying drawings and embodiments.

[0077] Example 1. Figure 1-3As shown, a charging plug device for a three-dimensional charging station is characterized by comprising a charging plug device mounting assembly, two charging plug connectors 6, and two plug-in main docking guide assembly.

[0078] like Figure 4-9 As shown, the charging plug device installation assembly includes a first connecting plate 1, a second connecting plate 2, and a third connecting plate 3 arranged from left to right. The second connecting plate 2 is located between the first connecting plate 1 and the third connecting plate 3. Four support rod mounting holes 11 are provided on the first connecting plate 1. The central axis of each support rod mounting hole 11 is perpendicular to the side of the second connecting plate 2 away from the first connecting plate 1. The left end of each support rod 21 is hingedly connected to a support rod mounting hole 11; the right end of each support rod 21 is fixed to the second connecting plate 2; each support rod 21 is fitted with a spring 4, one end of the spring 4 is in contact with the first connecting plate 1, and the other end is in contact with the second connecting plate 2.

[0079] Each plug-in main docking guide assembly includes a main guide rod 5 and a main guide rod guide sleeve 52. Each main guide rod 5 is located on the second connecting vertical plate 2 and each main guide rod guide sleeve 52 is located on the third connecting vertical plate 3.

Among the three charging contact assemblies, one is a DC power supply positive charging contact assembly, one is a DC power supply negative charging contact assembly, and one is a grounding charging contact assembly. When the two charging connectors 6 are docked, the two charging contacts 63 in each charging contact assembly make contact. Of the two charging contacts 63 in each charging contact assembly, one is a conductive rod and the other is a conductive socket.
