Description

Technical Field

[0001] The present invention relates to the technical field of new energy charging piles, and in particular to an intelligent new energy charging pile with a fault warning function. Background Art

[0002] As a core supporting infrastructure for the development of new energy vehicles, new energy charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or wall and installed in parking lots or charging stations in public buildings and residential communities. They can charge various models of electric vehicles at different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] The current transmitted by the charging pile during the charging process is large. As the usage time increases, the temperature of the charging head will continue to rise. The existing charging piles are not convenient for early warning of the high temperature of the charging head. If the heat is not dissipated in time, the internal components may melt due to excessive temperature, resulting in a short circuit and causing the charging pile to be damaged and unable to be used normally. In addition, when dissipating the heat of the charging head in rainy weather, most of the existing charging piles are unable to clean the rainwater attached to the surface of the charging head. During the heat dissipation process, the rainwater attached to the surface of the charging head may enter the interior of the body, thereby causing a short circuit in the electronic components inside the charging pile, affecting subsequent use.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original one. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent new energy charging pile with a fault warning function to solve the problems raised by the above background technology. The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: an intelligent new energy charging pile with a fault warning function, comprising a charging pile body and a charging gun head, wherein a protective plate is fixedly installed on the outer surface of the charging pile body at the plug interface of the charging gun head, a temperature sensor is fixedly installed inside the protective plate, the charging pile body is provided with a plug slot, a charging socket is movably installed inside the plug slot, and an electromagnet is fixedly installed inside the charging pile body;

[0007] An overheat protection component is provided inside the socket to provide heat dissipation protection for an overheated charging gun head;

[0008] A position limiting cleaning component is arranged in the inner wall of the charging pile body. The position limiting cleaning component is used to clean the residual water droplets on the charging gun head when the charging gun head is undergoing heat dissipation treatment, and to limit the charging gun head.

[0009] Preferably, the overheat protection assembly includes a movable groove that is symmetrical up and down about the horizontal center line of the plug-in slot, a fixed rack is installed inside the movable groove, and the plug-in slot is hexagonal when viewed from the side.

[0010] Preferably, a limiting slot is provided on the charging socket, and a connecting rod is fixedly installed at both the upper and lower ends of the charging socket, a rotating gear is fixedly installed at the outer end of the connecting rod, the rotating gear is meshed with the fixed rack, and a cooling fan is installed on the back of the charging socket.

[0011] Preferably, the upper end of the connecting rod 1 is rotatably connected to the connecting block 1, the connecting block 1 is connected to the connecting block 2 through a rod, the connecting block 2 is slidably installed inside the charging pile body, and the connecting rod 2 is fixedly installed on the connecting block 2, and the connecting rod 2 is slidably installed inside the charging pile body.

[0012] Preferably, the left end of the connecting rod 2 is connected to the electromagnet through a spring, the lower end of the electromagnet is connected to the limiting block 1 through a spring, the limiting block 1 and the limiting groove are mutually engaged, and the limiting block 1 is trapezoidal when viewed from the front.

[0013] Preferably, the limit cleaning assembly includes a clamping member slidably installed inside the charging pile body, the bottom of the clamping member is provided with an extrusion block movably installed through a slider, the inner surface of the clamping member and the extrusion block are fitted with a sponge, and the upper end of the slider is fixedly installed with a movable rack.

[0014] Preferably, a limit block 2 is installed inside the clamping member through spring sliding, and tooth blocks are fixedly installed on both sides of the limit block 2. The lower end of the limit block 2 is set to an arc shape, and the limit block 2 is engaged with the groove on the charging gun head.

[0015] Preferably, a rotating gear 2 is rotatably installed inside the clamping member, and the rotating gear 2 forms a transmission structure through a transmission belt. The rotating gears 2 on both sides of the transmission assembly are respectively engaged with the movable rack and the tooth blocks on the two sides of the limit block.

[0016] Preferably, the clamping member is fixedly connected to the connecting block 2 via the connecting rod 2, and two clamping members are symmetrically arranged up and down about the horizontal center line of the charging gun head.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention installs a temperature sensor in a protective plate provided on the surface of the charging pile body, so that the charging gun head entering the plug slot is monitored in real time and a high temperature warning is provided, thereby ensuring that the temperature of the charging gun head is within a reasonable usage range. When it is detected that the surface temperature of the charging gun head is too high, the temperature sensor cuts off the power to the body and changes the current direction of the electromagnet inside the charging pile body, thereby causing its magnetism to flip, thereby releasing the limit on the charging socket, and pushing the charging socket backward by moving the connecting block downward so that it no longer contacts the charging gun head. During the backward movement of the charging socket, the rotating fan connected to the back is simultaneously rotated to face the charging gun head so that it blows air to dissipate heat for the charging gun head. The falling clamping piece is pressed against the surface of the charging gun head, and moisture or dust attached to the surface is absorbed and wiped by a sponge to prevent rainwater and dust from entering the body.

[0019] When the temperature sensor detects that the temperature of the charging gun head is too high, the circuit is disconnected, the direction of the current inside the electromagnet is changed, and its magnetism is changed. At the same time, the electromagnet changes from the original repulsion of the connecting rod 2 and the limit block 1 to adsorption, thereby driving the connecting block 2 to move downward, and sucking the limit block 1 out of the groove above the charging socket to release the limit on the limit block 1, so that the limit block 1 can move backward by the push of the rod when the connecting block 2 falls. At the same time, the rotating gear above the charging socket and the fixed rack engage in the process of backward movement, so that the charging socket can be flipped 180 degrees during the backward movement, so that the cooling fan can face the charging gun head directly and dissipate heat efficiently.

[0020] Furthermore, as the connecting rod 2 drives the clamping part to move downward, the charging gun head will abut against the limit block 2 in the clamping part when entering the interior of the charging pile body, thereby pushing the limit block 2 to move upward. The upward moving limit block 2 drives the moving rack to move through the rotating gear 2 and the transmission belt. At the same time, the moving rack simultaneously drives the extrusion block inward during the movement, so that the sponge arranged on the inner wall absorbs the water droplets attached to the surface of the charging gun head. At the same time, as the charging gun head continues to go deeper, the limit block 2 will engage with the groove opened on the surface of the charging gun head to limit the charging gun head and prevent it from being pulled out for use during the heat dissipation process.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 7 The present invention provides a technical solution: an intelligent new energy charging pile with a fault warning function, wherein a protective plate 3 is fixedly installed on the outer surface of the charging pile body 1 at the plug interface of the charging gun head 2, a temperature sensor 31 is fixedly installed inside the protective plate 3, the charging pile body 1 is provided with a plug slot 4, a charging socket 5 is movably installed inside the plug slot 4, and an electromagnet 6 is fixedly installed inside the charging pile body 1;

[0031] The overheat protection component is arranged inside the plug slot 4, and the overheat protection component provides heat dissipation protection for the overheated charging gun head 2;

[0032] The position limiting cleaning component is arranged in the inner wall of the charging pile body 1. The position limiting cleaning component is used to clean the residual water droplets on the charging gun head 2 when the charging gun head 2 is undergoing heat dissipation treatment, and to limit the charging gun head 2.

[0033] As an embodiment of the present invention, the overheat protection assembly includes a movable groove 7 that is symmetrical up and down about the horizontal center line of the plug-in slot 4. A fixed rack 701 is installed inside the movable groove 7. The plug-in slot 4 is hexagonal when viewed from the side.

[0034] As an embodiment of the present invention, a limiting slot 501 is provided on the charging socket 5, and a connecting rod 502 is fixedly installed at both the upper and lower ends of the charging socket 5, a rotating gear 503 is fixedly installed at the outer end of the connecting rod 502, and the rotating gear 503 is engaged with the fixed rack 701. A cooling fan 504 is installed on the back of the charging socket 5.

[0035] As an embodiment of the present invention, the upper end of the connecting rod 1 502 is rotatably connected to the connecting block 1 8, the connecting block 1 8 is connected to the connecting block 2 10 through the rod 9, the connecting block 2 10 is slidably installed inside the charging pile body 1, and the connecting rod 2 11 is fixedly installed on the connecting block 2 10, and the connecting rod 2 11 is slidably installed inside the charging pile body 1.

[0036] As an embodiment of the present invention, the left end of the connecting rod 2 11 is connected to the electromagnet 6 through a spring, and the lower end of the electromagnet 6 is connected to the limiting block 12 through a spring. The limiting block 12 and the limiting groove 501 are mutually engaged, and the limiting block 12 is trapezoidal when viewed from the front.

[0037] By installing a temperature sensor 31 in the protective plate 3 set on the surface, it can monitor the charging gun head 2 entering the plug slot 4 in real time. When it is detected that the surface temperature of the charging gun head 2 is too high, the temperature sensor 31 cuts off the power to the charging pile body 1 and inputs a current in the opposite direction to the electromagnet 6, so that the magnetic field of the electromagnet 6 is reversed, causing the electromagnet 6 to adsorb the originally repelling connecting rod 2 11 and limit block 1 12, contacting the limit of the charging socket 5 by the limit block 12, and driving the connecting block 2 10 to slide downward through the connecting rod 2 11, so that the connecting block 2 10 pushes the connecting block 1 8 to move backward in the movable groove 7 through the rod 9. At the same time, the rotating gear 1 503 connected at the bottom engages with the fixed rack 701, so that the charging socket 5 rotates 180 degrees during the backward movement, thereby directing the cooling fan 504 directly towards the charging gun head 2 to quickly dissipate heat.

[0038] As an embodiment of the present invention, the limiting cleaning assembly includes a clamping member 13 slidably installed inside the charging pile body 1, and the bottom of the clamping member 13 is provided with an extrusion block 1301 movably installed through a slider 1302. A sponge is provided on the inner surface of the clamping member 13 and the extrusion block 1301, and a movable rack 1303 is fixedly installed on the upper end of the slider 1302.

[0039] As an embodiment of the present invention, a limit block 2 1304 is installed inside the clamping member 13 through spring sliding, and tooth blocks are fixedly installed on both sides of the limit block 2 1304. The lower end of the limit block 2 1304 is set to an arc shape, and the limit block 2 1304 is engaged with the groove on the charging gun head 2.

[0040] As an embodiment of the present invention, a rotating gear 2 14 is installed inside the clamping member 13, and the rotating gear 2 14 forms a transmission structure through a transmission belt. The rotating gear 2 14 on both sides of the transmission assembly are respectively engaged with the tooth blocks on the side of the movable rack 1303 and the limit block 2 1304.

[0041] As an embodiment of the present invention, the clamping member 13 is fixedly connected to the second connecting block 10 through the second connecting rod 11 , and two clamping members 13 are symmetrically arranged up and down about the horizontal center line of the charging gun head 2 .

[0042] The connecting rod 2 11 drives the clamping part 13 to fall synchronously, so that the charging gun head 2 abuts against the limit block 2 1304 at the lower end of the clamping part 13 when entering the plug-in slot 4, causing the limit block 2 1304 to move upward, and the transmission part composed of the rotating gear 2 14 and the transmission belt arranged inside the clamping part 13 drives the moving rack 1303 to move. As the moving rack 1303 moves, it will synchronously drive the extrusion block 1301 to fit the charging gun head 2, so that the sponge arranged on the inner surface of the clamping part 13 absorbs the water droplets attached to the surface of the charging gun head 2, until the limit block 2 1304 is engaged with the groove opened on the charging gun head 2, thereby completing the limiting of the charging gun head 2.

[0043] Working principle: When the charging gun head 2 is inserted into the charging pile body 1, the temperature sensor 31 set inside the protective plate 3 will first monitor the surface temperature of the charging gun head 2. When the temperature does not reach the threshold, the device can be used normally. When the surface temperature of the charging gun head 2 is higher than the threshold, the temperature sensor 31 will control the device to cut off the power, and at the same time input the current opposite to the original one to the internal electromagnet 6, thereby changing the magnetic direction of the electromagnet 6, so that the electromagnet 6 can adsorb the originally repelling connecting rod 2 11 and the limit block 12, and suck the limit block 12 out of the limit groove 501, contact the limit block 12 to limit the charging gun head 2, and at the same time, the electromagnet 6, the connecting rod 2 11 moves downward, synchronously driving the connecting block 2 10 to move downward. When the connecting block 2 10 moves downward, it pushes the connecting block 1 8 to move backward in the movable groove 7 through the rod 9, so that the connecting block 1 8 can drive the charging socket 5 to move backward. At the same time, the rotating gear 1 503 fixedly installed on the charging socket 5 through the connecting rod 1 502 engages with the fixed rack 701 installed inside the movable groove 7, so that the charging socket 5 is flipped 180 degrees during the backward movement through the rotation of the rotating gear 1 503, so that the cooling fan 504 on the back of the charging socket 5 is facing the charging gun head 2, which dissipates heat quickly and effectively.

[0044] When the connecting rod 1 502 moves downward, the clamping member 13 will be driven to fall at the same time, so that the clamping member 13 will pop out from the inside of the charging pile body 1 when the charging gun head 2 enters. At the same time, the charging gun head 2 that enters will abut against the limit block 2 1304 set on the clamping member 13, so that the limit block 2 1304 will move upward. When the limit block 2 1304 moves upward, the tooth blocks on both sides will mesh with the rotating gear 2 14. At the same time, the rotating gear 2 14 drives the rotating gear 2 14 on the other side to mesh with the moving gear 2 through the transmission belt. The movable rack 1303 is engaged, thereby driving the extrusion block 1301 to move closer to the charging gun head 2 by moving the rack 1303, and absorbing the moisture attached to the surface of the charging gun head 2 through the sponge attached to the inner side of the clamping part 13, preventing rainwater from dripping into the body during the heat dissipation process. At the same time, as the charging gun head 2 continues to penetrate deeper, the limit block 2 1304 is stuck in the groove opened on the charging gun head 2, limiting the charging gun head 2 to prevent the charging gun head 2 from being pulled out and continued to be used during the heat dissipation process.
