Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and particularly relates to a household charging pile for electric vehicles. Background Technique

[0002] With the further development of automobiles, electric vehicles are gradually accepted by people. The advantage of electric vehicles is energy conservation and emission reduction in urban commuting, which can reduce the use cost of automobiles. With the popularization of electric vehicles, people usually install household charging piles on private parking spaces and use household electricity to charge electric vehicles, which is not only convenient but also can further save the charging cost.

[0003] Among them, in an underground garage, when a private parking space is neither against a wall nor against a column, a suspended charging pile is often adopted. By fixing the charging pile on the wall top above the parking space, it does not occupy the ground space and thus will not be collided by vehicles, having the advantage of high safety.

[0004] Since the suspended charging pile is fixed on the wall top, the position of the charging gun is relatively high. Therefore, the suspended charging pile usually has a lifting function. The charging pile is lowered through a lifting structure to facilitate the taking of the charging gun. For example, a suspended charging pile disclosed in Chinese Patent CN221049535U can lift the charging pile body through a lifting drive assembly to facilitate the user to take the charging gun. However, the existing suspended charging piles generally have the following disadvantages:

[0005] The existing suspended charging piles often lift the charging pile body. Since the charging pile body is heavy, a driving structure with a relatively large power is required for driving, and the energy-saving performance is poor. Moreover, a certain movable length needs to be reserved for the cable connected to the charging pile, so the line is relatively messy. Content of the Utility Model

[0006] The purpose of the utility model aims to solve at least one of the technical defects described in the background technique.

[0007] For this reason, an object of the utility model is to provide a household charging pile for electric vehicles, aiming to solve the problem of poor energy-saving performance of the existing suspended charging piles in the prior art.

[0008] To achieve the above object, an embodiment of one aspect of the utility model provides a household charging pile for electric vehicles, including a positioning seat. A charging pile body is fixedly installed at the bottom of the positioning seat. A motor is fixedly installed at the bottom of the positioning seat. The output end of the motor is fixedly connected with a winding roller. A traction rope is fixedly connected to the outer surface of the winding roller. One end of the traction rope far away from the winding roller is fixedly connected with an L-shaped plate. A cylinder is fixedly connected to the inner side of the L-shaped plate. A limiting plate is fixedly connected to one end of the cylinder far away from the L-shaped plate.

[0009] The beneficial effects are as follows:

[0010] First, the power cord connected to the charging gun can be wound around the surface of the cylinder. Then, by controlling the rotation of the roller with a motor, the towing rope is wound up, and the L-shaped plate can be lifted, so as to achieve the purpose of lifting the charging gun. The electric vehicle on the lower parking space is charged by lifting the charging gun. The structure to be lifted has a small weight, so a motor with a relatively small power can be used, thus achieving the purpose of energy conservation. Moreover, the charging pile body does not need to be lifted, so the cable connected to the charging pile body does not need to reserve a movable length, and thus the circuit is more regular;

[0011] Second, by setting the L-shaped plate and fixing the cylinder inside the L-shaped plate, when the connection line of the charging gun is wound around the surface of the cylinder, the center of gravity is still located in the middle of the L-shaped plate. Therefore, the L-shaped plate will not tilt. With the setting of the limiting plate, the power cord connected to the charging gun wound around the surface of the cylinder will not fall off, thus ensuring the reliability of the structure.

[0012] Preferably, according to any of the above solutions, a positioning ring is fixedly connected to the bottom of the positioning seat. A jack is opened at the bottom of the positioning ring, a rotating groove communicating with the jack is opened at the top of the positioning ring, a counterbore is opened at one side of the rotating groove away from the jack, a positioning column is fixedly connected to the top of the charging pile body, and a clamping block is fixedly connected to the outer surface of the positioning column.

[0013] The beneficial effects are as follows: The charging pile body is inserted into the positioning ring through the positioning column, and then by rotating the charging pile body, the clamping block is rotated into the counterbore through the rotating groove, thus completing the installation of the charging pile body. Due to the limitation of the counterbore on the clamping block, the charging pile body will not rotate and will not fall off, thus achieving the purpose of facilitating the installation of the charging pile body. When disassembling, only need to push the charging pile body upward to rotate and disassemble it, thus achieving the purpose of facilitating disassembly. Therefore, when maintenance is needed later, it is convenient to disassemble and repair the charging pile body.

[0014] Preferably, according to any of the above solutions, a connecting rod is fixedly connected to the bottom of the positioning seat. The bottom end of the connecting rod is rotatably connected to a positioning cylinder. One side of the positioning cylinder is rotatably connected to a circular ring. A pressing rod and a pulling rod are fixedly connected to the outer surface of the circular ring. The end of the pulling rod away from the circular ring is fixedly connected to a pulling rope. A support seat is fixedly connected to the bottom of the positioning seat. A first button switch and a second button switch are fixedly installed at the bottom of the support seat. A first limiting rod and a second limiting rod are fixedly connected to the bottom of the positioning seat.

[0015] The beneficial effects are as follows: The pressing rod can be controlled to press the first button switch or the second button switch through the pull rope, so as to control the lifting of the charging gun. Since the pull rope hangs down above the parking space, it is convenient for the user to pick up and place the charging gun. The setting of the first limiting rod and the second limiting rod facilitates the alignment of the pressing rod with the first button switch or the second button switch, so it is convenient for the operator to control the pressing rod to press the first button switch or the second button switch.

[0016] Preferably, according to any of the above solutions, it further includes a power box with a lock.

[0017] The beneficial effects are as follows: The power box can be installed on the column or wall closest to the parking space to control the power supply of the charging pile body and the motor. Thus, when not in use, the power supply of the charging pile body and the motor can be disconnected through the air switch in the power box, and then the power box can be locked to prevent others from stealing electricity.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The present utility model provides a household charging pile for electric vehicles.

[0028] Embodiment 1:

[0029] As Figure 1-2 shown, it includes a positioning seat 1. There are multiple through holes 15 on the positioning seat 1. Expansion bolts can be inserted into the through holes 15, so that the positioning seat 1 can be fixed on the top of the wall of the underground garage through the expansion bolts. A charging pile body 2 is fixedly installed at the bottom of the positioning seat 1, and a motor 3 is fixedly installed at the bottom of the positioning seat 1. The output end of the motor 3 is fixedly connected to a winding roller 31. A traction rope 32 is fixedly connected to the outer surface of the winding roller 31. By driving the winding roller 31 to rotate forward and backward by the motor 3, the purpose of taking in and releasing the traction rope 32 can be achieved. One end of the traction rope 32 away from the winding roller 31 is fixedly connected to an L-shaped plate 33. A cylinder 34 is fixedly connected to the inner side of the L-shaped plate 33. A limiting plate 35 is fixedly connected to one end of the cylinder 34 away from the L-shaped plate 33. The cable connected to the charging gun on the charging pile body 2 can be wound around the surface of the cylinder 34, and the traction rope 32 is fixedly connected to the top of the L-shaped plate 33. After the cable is wound around the surface of the cylinder 34, it is located directly below the L-shaped plate 33. Therefore, the L-shaped plate 33 will not tilt excessively. With the restriction of the limiting plate 35, the cable connected to the charging gun is not easily detached when wound around the surface of the cylinder 34.

[0030] Embodiment 2:

[0031] As Figure 2-3As shown, on the basis of the first embodiment, a positioning ring 11 is fixedly connected to the bottom of the positioning seat 1. A jack 12 is opened at the bottom of the positioning ring 11, and a rotating groove 13 communicating with the jack 12 is opened at the top of the positioning ring 11. A counterbore 14 is opened on one side of the rotating groove 13 away from the jack 12. A positioning post 21 is fixedly connected to the top of the charging pile body 2. The positioning post 21 can be inserted into the middle of the positioning ring 11. A clamping block 22 is fixedly connected to the outer surface of the positioning post 21. The clamping block 22 can be inserted through the jack 12 and then rotated through the rotating groove 13 so that the clamping block 22 is staggered from the jack 12. When the clamping block 22 rotates to the position of the counterbore 14, it can fall into the counterbore 14, so that the charging pile body 2 cannot be rotated without pushing the charging pile body 2 upward, achieving the purpose of fixing the charging pile body 2.

[0032] Embodiment Three:

[0033] As Figure 2 and Figure 4As shown, on the basis of the first or second embodiment, the bottom of the positioning seat 1 is fixedly connected with a connecting rod 4, the bottom end of the connecting rod 4 is rotatably connected with a positioning cylinder 5, the bottom end of the connecting rod 4 is fixedly connected with a positioning shaft 41, the positioning cylinder 5 is sleeved on the surface of the positioning shaft 41, so as to realize the rotation connection, and the outer surface of the bottom end of the positioning shaft 41 is threadedly connected with a nut 42, which can limit the positioning cylinder 5 to avoid the problem of the positioning cylinder 5 slipping, and a thrust bearing 43 is also provided between the nut 5 and the positioning cylinder 5, which can avoid the nut 5 following the rotation when the positioning cylinder 5 rotates. In order to solve the problem of nut 5 falling off, a ring 51 is rotatably connected to one side of the positioning cylinder 5, and a pressure rod 52 and a pull rod 53 are fixedly connected to the outer surface of the ring 51, and a pull rope 54 is fixedly connected to the end of the pull rod 53 away from the ring 51. The weight of the pressure rod 52 is greater than the total weight of the pull rod 53 and the pull rope 54, thereby ensuring that when no force is applied to the pull rope 54, the pressure rod 52 sags and the pull rod 53 rises. In addition, a limiting column 510 is fixedly connected to the surface of the positioning cylinder 5, which can limit the pull rod 53 to prevent the pull rod 53 and the pressure rod 52 from being in a vertical state. The bottom of the seat 1 is fixedly connected with a support 55, and the bottom of the support 55 is fixedly installed with a first button switch 56 and a second button switch 57. The first button switch 56 and the second button switch 57 are respectively connected in series in the forward rotation and flipping circuits of the motor 3. By rotating the positioning cylinder 5, the end of the pressure rod 52 corresponds to the first button switch 56 or the second button switch 57, and then by pulling the pull rope 54 downward, the pressure rod 52 presses the first button switch 56 or the second button switch 57 upward, thereby controlling the forward rotation or flipping of the motor 3 to achieve the retracting and releasing of the traction rope 32. For purpose, the bottom of the positioning seat 1 is fixedly connected with a first limit rod 58 and a second limit rod 59. When the positioning cylinder 5 is rotated, when the pressure rod 52 abuts against the first limit rod 58, the end of the pressure rod 52 corresponds to the first button switch 56. When the positioning cylinder 5 is rotated, when the pressure rod 52 abuts against the second limit rod 59, the end of the pressure rod 52 corresponds to the second button switch 57. Therefore, the setting of the first limit rod 58 and the second limit rod 59 facilitates the adjustment of the rotation angle of the positioning cylinder 5, so that the pressure rod 52 can quickly and accurately correspond to the first button switch 56 or the second button switch 57.

[0034] Embodiment 4:

[0035] like Figure 1As shown in the figure, on the basis of the first embodiment, the second embodiment or the third embodiment, it further includes a power supply box 6 with a lock, and the cabinet door of the power supply box 6 can be locked by the lock to prevent others from opening it casually. An air switch is installed in the power supply box 6, and the power supply lines of the charging pile body 2 and the motor 3 are passed into the power supply box 6 and connected to the air switch. Therefore, the power supply lines of the charging pile body 2 and the motor 3 can be disconnected through the air switch. Therefore, when not in use, the circuit is powered off through the air switch, and then the cabinet surface of the power supply box 6 is locked, so as to prevent others from casually pulling the pull rope 54 and causing the charging gun to fall to charge other people's electric vehicles.

[0036] The working principle of the present utility model is as follows: During installation, the positioning seat 1 is fixed on the top of the wall in the underground garage using expansion bolts, and then the charging pile body 2 is lifted so that the positioning post 21 is inserted into the positioning ring 11 and the clamping block 22 is inserted into the jack 12. Then, the charging pile body 2 is rotated so that the clamping block 22 enters the counterbore 14. The power supply box 6 is fixed on the column or wall closest to the parking space. The power supply lines of the charging pile body 2 and the motor 3 are introduced into the power supply box 6 and connected to the air switch in the power supply box 6, thus completing the installation.

[0037] During use, use the key to open the power supply box 6, turn on the air switch to supply power to the charging pile body 2 and the motor 3, and then rotate the positioning cylinder 5 through the pull rope 54 so that the pressure rod 52 corresponds to the first button switch 56. Then, pull down the pull rope 54, and the pressure rod 52 presses the first button switch 56, and the winding roller 31 releases the towing rope 32. Thus, the L-shaped plate 33 descends, and the charging gun can be taken off from the surface of the cylinder 34 to charge the electric vehicle.

[0038] After charging is completed, wind the charging gun and the cable line of the lower part around the surface of the cylinder 34, and then rotate the positioning cylinder 5 through the pull rope 54 so that the pressure rod 52 corresponds to the second button switch 57. Then, pull down the pull rope 54, and the pressure rod 52 presses the second button switch 57, and the winding roller 31 rotates to wind up the towing rope 32, thereby raising the charging gun. The cable line connected to the charging gun that is not wound around the surface of the cylinder 34 will fold as the L-shaped plate 33 rises, thus not affecting the parking of the electric vehicle. After the charging gun is raised, turn off the air switch and lock the power supply box 6.
