[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-4 This utility model discloses a photovoltaic energy storage and charging integrated device, comprising:

[0027] Energy storage unit 1 is used for storing and discharging energy;

[0028] Photovoltaic carport 2 is used to convert solar energy into electrical energy and store the electrical energy in energy storage unit 1. Multiple parking spaces are set under photovoltaic carport 2.

[0029] Charging pile 3, the charging pile 3 is equipped with a charging cable for outputting electrical energy from the energy storage unit 1, and the end of the charging cable away from the charging pile 3 is equipped with a charging head for connecting to the vehicle.

[0030] At least one suspended moving unit 4 is installed on the photovoltaic canopy 2 and is detachably connected to the charging head, enabling the charging cable to be suspended in the air;

[0031] The drive unit 5, located on the photovoltaic carport 2, can drive one or more suspended moving units 4 to move the charging head along the length of each parking space.

[0032] This invention, by setting a suspended moving unit 4 corresponding to the number of parking spaces on the photovoltaic carport 2, and detachably connecting the suspended moving unit 4 to the charging head, allows the charging cable and charging head to be suspended and moved by the suspended moving unit 4 after the drive unit 5 is started, thereby avoiding the problem of the charging cable rubbing against the ground during the process of moving to the vehicle charging port.

[0033] It should be noted that the energy storage unit 1, the photovoltaic carport 2, and the charging pile 3 are common knowledge in this field, so their specific structural composition and working principle will not be described in detail in this article.

[0034] In one embodiment, the photovoltaic carport 2 includes a roof 21 and at least one support column 22 disposed at the bottom of the roof 21, the charging pile 3 is located below the roof 21, and an equipment mounting beam 23 is also disposed at the bottom of the roof 21;

[0035] The suspended moving unit 4 includes a first bracket 41 detachably mounted on the equipment mounting beam 23. A reciprocating screw 42 is rotatably mounted on the side of the first bracket 41 away from the equipment mounting beam 23. A second bracket 43 is detachably connected to the equipment mounting beam 23 at the end of the reciprocating screw 42 away from the first bracket 41. The reciprocating screw 42 is rotatably connected to the second bracket 43. A screw nut 44 is mounted on the reciprocating screw 42, which can reciprocate along the axis of the reciprocating screw 42 when the reciprocating screw 42 rotates. A suspension frame 45 is mounted at the bottom of the screw nut 44. The bottom end of the suspension frame 45 is detachably connected to the charging head. A guide rod 46 is provided between the first bracket 41 and the second bracket 43, passing through the suspension frame 45. Both the first bracket 41 and the suspension frame 45 are fixedly connected to the charging cable, and the length of the charging cable between the first bracket 41 and the suspension frame 45 is not less than the maximum distance that the screw nut 44 can move.

[0036] With this design, when the reciprocating screw 42 rotates, the suspension bracket 45, whose movement is restricted by the guide rod 46, moves back and forth along the axis of the reciprocating screw 42 under the drive of the screw nut 44. This allows the charging head mounted on it to change its position, so that the charging head can be inserted into the vehicle charging port at different locations after being pulled off the suspension bracket 45. At the same time, since the length of the charging cable between the first bracket 41 and the suspension bracket 45 is not less than the maximum distance that the screw nut 44 can move, the movement of the charging head is not limited by the length of the charging cable.

[0037] In one embodiment, a protective barrier 6 is provided at the bottom of the canopy 21 to prevent the vehicle from colliding with the suspension frame 45. The bottom end of the suspension frame 45 is inserted into the protective barrier 6. The protective barrier 6 has a sliding groove for the suspension frame 45 to move back and forth and a loading and unloading hole for the charging head to be picked up and put in.

[0038] This design uses the protective barrier 6 as a reminder and warning to prevent the vehicle from getting too close to the suspension frame 45 when it is parked for charging, thus avoiding a collision with the suspension frame 45 and protecting the suspension frame 45 in different positions.

[0039] In one embodiment, the drive unit 5 includes a drive motor 51 mounted on the equipment mounting beam 23. The output end of the drive motor 51 is provided with a drive shaft 52. A gear mounting seat 53 corresponding to the suspension moving unit 4 is sleeved on the drive shaft 52. The gear mounting seat 53 is detachably connected to the equipment mounting beam 23. A driving bevel gear 54 is rotatably mounted on the gear mounting seat 53. The drive unit 5 also includes a driven bevel gear 55 mounted on the reciprocating screw 42. The driving bevel gear 54 meshes with the driven bevel gear 55. A turntable 56 is detachably mounted on the drive shaft 52, which can rotate with the drive shaft 52 and move axially along the drive shaft 52. An eccentric block 57 with the same rotation radius is provided on the opposite side of the turntable 56 and the driving bevel gear 54. A pushing component 58 is provided on the equipment mounting beam 23 for driving the turntable 56 to move closer to and away from the driving bevel gear 54.

[0040] With this design, when the pushing component 58 pushes the turntable 56 close to the driving bevel gear 54, since the eccentric block 57 corresponding to the turntable 56 and the eccentric block 57 corresponding to the driving bevel gear 54 have the same rotation radius, one eccentric block 57 moves into the rotation area of ​​the other eccentric block 57, which enables the turntable 56 and the driving bevel gear 54 to rotate synchronously. Under the transmission action of the driven bevel gear 55, the reciprocating screw 42 is driven to rotate. The gear mounting base 53, the driving bevel gear 54, the driven bevel gear 55, the turntable 56 and the pushing component 58 can all be modularly installed according to the number of suspension moving units 4, so that this drive unit 5 can be modularly adjusted according to various parking space requirements, and only a single drive motor 51 is needed to drive multiple suspension moving units 4.

[0041] In actual operation, each suspension moving unit 4 is equipped with a corresponding controller. When the user needs to charge, they press the controller near the corresponding parking space. If the drive motor 51 is stopped at this time, the drive motor 51 will be started. If the drive motor 51 is already running, the control push component 58 will push the turntable 56 closer to the drive bevel gear 54, so that the suspension moving unit 4 of the corresponding parking space will move. When the suspension frame 45 moves to the required position, the user stops operating the controller, so that the corresponding push component 58 pushes the turntable 56 away from the drive bevel gear 54. At the same time, if no controller is in operation at this time, the drive motor 51 will stop. If there is still a controller in operation, the drive motor 51 will continue to work, so that each suspension moving unit 4 can work without interfering with each other.

[0042] In one embodiment, the pushing component 58 includes a mounting plate 581 detachably mounted on the equipment mounting beam 23. The mounting plate 581 is sleeved on the drive shaft 52, and the mounting plate 581 is located on the side of the turntable 56 away from the drive bevel gear 54. An electromagnet 582 is provided on the side of the mounting plate 581 near the turntable 56. When the electromagnet 582 is energized, it repels the turntable 56. A tension spring 583 is rotatably provided between the mounting plate 581 and the turntable 56. When the electromagnet 582 is energized, the eccentric block 57 on the turntable 56 is located within the rotation area of ​​the eccentric block 57 on the drive bevel gear 54. When the electromagnet 582 is de-energized, the eccentric block 57 on the turntable 56 is not located within the rotation area of ​​the eccentric block 57 on the drive bevel gear 54.

[0043] This design allows the electromagnet 582 to be switched on and off, which, in conjunction with the tension spring 583, changes the relative position of the turntable 56 and the drive bevel gear 54, thus achieving the effect of moving the turntable 56 closer to or further away from the drive bevel gear 54. The entire drive assembly 58 has a simple structure and low assembly cost.

[0044] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0045] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0046] Additionally, "multiple" refers to two or more.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
