Description

Technical Field

[0001] This invention relates to the field of new energy charging equipment technology, and in particular to a new energy charging device with a protective device. Background Technology

[0002] New energy charging devices are systems used to provide electrical energy to new energy vehicles (such as electric vehicles and plug-in hybrid electric vehicles). They are an important component of new energy transportation and green energy systems, encompassing the integration of technologies from multiple fields, including power electronics, communication, control, and new energy storage technologies.

[0003] The prior art publication CN115257422B provides a new energy vehicle charging pile with a charging cable protection device. By setting a retractable wire limiting component, the protection range of the charging cable protection mechanism can be adjusted according to the actual situation. Moreover, the adaptive protection unit can automatically adjust the clamping range according to the model of the charging cable, thereby better protecting the charging cable and extending the service life of the charging cable.

[0004] Existing technologies provide protection for charging cables, but during the process of unplugging the charging gun from the charging station and inserting it into the car's charging port, when the charging station is used outdoors, rainwater may fall into the socket during the unplugging process, as existing technologies are not convenient for protecting the socket. After entering the socket, the rainwater may remain on the metal contacts or internal insulating components. Inserting the charging gun into the vehicle in a wet or waterlogged state may cause safety risks such as short circuits, leakage, corrosion, and electric arcs.

[0005] In summary, the existing technology lacks a technology that automatically waterproofs the charging gun's socket. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a new energy charging device with a protective device.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a new energy charging device with a protective device, including a charging pile, a cable fixedly installed inside the charging pile, a charging gun fixedly installed at the outer end of the cable, a waterproof mechanism fixedly connected inside the charging gun, an air pump fixedly installed on the inner wall of the charging pile, a transmission ring provided on one side of the air pump, a transmission mechanism rotatably connected to the transmission ring, and an anti-blocking mechanism rotatably connected inside the transmission ring.

[0008] Preferably, the charging pile has a charging gun port, and the inner wall of the charging gun port is movably connected to the charging gun.

[0009] Preferably, the outer wall of the cable is fixedly connected with multiple protective rings, the two ends of the protective rings are tapered, and the outer circle of the protective rings is embedded with multiple balls in a ring structure.

[0010] Preferably, the waterproof mechanism includes a main pipe, which is fixedly connected to the inner wall of the charging gun. Multiple air jet pipes are fixedly connected to the main pipe in a ring structure. The other end of each air jet pipe extends into the socket of the charging gun. An air guide hose is fixedly connected to one end of the main pipe. The other end of the air guide hose passes through the inner wall of the cable, extends into the charging pile, and is fixedly connected to a pipe connector. The pipe connector is fixedly connected to the output end of the air pump.

[0011] Preferably, the bottom end of the air pump is fixedly connected to a mounting bracket, the mounting bracket is fixedly connected to the inner wall of the charging pile, a filter tube is fixedly connected to the mounting bracket, one end of the filter tube is fixedly connected to a pipe connector, the pipe connector is fixedly connected to the input end of the air pump, and a transmission rack is fixedly connected to the mounting bracket.

[0012] Preferably, the inner wall of the transmission ring has an annular groove, a sliding frame is fixedly connected to the transmission ring, the other end of the sliding frame extends into the gun port and is fixedly connected to a contact plate, the contact plate is slidably engaged with the inner wall of the gun port, a plurality of springs are fixedly connected to one side of the contact plate, the other end of the springs is fixedly connected to the inner wall of the gun port, and the other side of the contact plate is movably in contact with the end of the charging gun.

[0013] Preferably, a cleaning ring is slidably fitted at the bottom end of the transmission ring, a toothed ring is fixedly connected to the outer wall of the cleaning ring, the toothed ring meshes with the transmission rack for transmission, a plurality of bristle combs are slidably fitted on the inner wall of the cleaning ring in an annular structure, a tension spring is fixedly connected to the outer end of the bristle comb, the other end of the tension spring is fixedly connected to the cleaning ring, an arc-shaped block is fixedly connected to the bottom end of the transmission ring, and one end of the bristle comb is in slidable contact with the arc-shaped block.

[0014] Preferably, the transmission mechanism includes a universal joint, which is rotatably connected to the sliding frame. A drive wheel is fixedly connected to the top of the universal joint, and a fixed rack is engaged with one side of the drive wheel. One end of the fixed rack is fixedly connected to the mounting frame, and a driven wheel is fixedly connected to the bottom of the universal joint.

[0015] Preferably, the anti-clogging mechanism includes a rotating ring, a limiting ring fixedly connected to the outer wall of the rotating ring, the limiting ring being rotatably connected to the inner wall of the annular groove, an annular rack fixedly connected to the inner wall of the limiting ring, the annular rack being meshed with a driven wheel for transmission, and bristles fixedly connected to the inner wall of the rotating ring in an annular structure, the bristles being in frictional contact with the outer wall of the filter tube.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. By incorporating a waterproof mechanism inside the charging gun, after the charging gun is unplugged, high-pressure air generated by an air pump is sprayed out from each socket of the charging gun through the jet pipes on the waterproof mechanism. In rainy weather, when rainwater flows to the sockets of the charging gun, the high-pressure air can form an air curtain in the socket area, reducing the possibility of rainwater directly entering the sockets and effectively preventing electrical faults caused by moisture intrusion. This significantly reduces the risk of electric shock or short circuit and improves the safety of users during charging operations. 2. By setting up a transmission ring, transmission mechanism and anti-blocking mechanism, when the charging gun is plugged into or unplugged from the charging pile, the contact plate is squeezed and the spring causes the transmission ring to move back and forth, thereby driving the bristles on the rotating ring to clean the outer wall of the filter tube at the air pump inlet. At the same time, under the action of the transmission mechanism, the rotating ring can rotate on its own. Through the structural self-cleaning mechanism, the high-pressure jetting capacity is maintained without decay, and the timeliness and effectiveness of automatic drainage in rainy weather are improved. 3. By setting a cleaning ring below the transmission ring, when the transmission ring drives the brush on the rotating ring to clean the outer wall of the filter tube, the cleaning ring can rotate under the action of the transmission rack. This allows the brush comb on the cleaning ring to automatically clean the adhering substances on the brush bristles, keeping the brush bristles clean, extending the service life of the brush bristles, and ensuring the effectiveness and consistency of each filter tube cleaning. At the same time, by setting multiple protective rings on the cable, the contact between the cable and the ground can be reduced, and the cable is suspended off the ground for protection, avoiding wear and achieving cable protection.

Detailed Implementation

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-9 The new energy charging device with protective devices shown includes a charging pile 1, a cable 2 installed and fixed inside the charging pile 1, a charging gun 3 installed and fixed at the outer end of the cable 2, a waterproof mechanism 4 fixedly connected inside the charging gun 3, an air pump 5 installed and fixedly installed on the inner wall of the charging pile 1, a transmission ring 6 provided on one side of the air pump 5, a transmission mechanism 7 rotatably connected to the transmission ring 6, and an anti-blocking mechanism 8 rotatably connected inside the transmission ring 6.

[0021] like Figure 4 As shown, the charging pile 1 has a charging gun port 101, and the inner wall of the charging gun port 101 is movably connected to the charging gun 3.

[0022] like Figure 4As shown, multiple protective rings 201 are fixedly connected to the outer wall of the cable 2. The two ends of the protective rings 201 are tapered, and multiple balls 202 are embedded in the outer circle of the protective rings 201 in a ring structure.

[0023] The protective ring 201 is made of wear-resistant nylon, enabling the cable 2 to be suspended off the ground. The tapered structure at both ends reduces the hooking and friction between the protective ring 201 and obstacles such as the ground and walls when the cable 2 is dragged, improving ease of use. The ball bearing 202 is made of stainless steel with a smooth surface, which can convert the sliding friction between the protective ring 201 and the contact surface into rolling friction, greatly reducing the wear of the cable 2 when dragging, while reducing dragging resistance, avoiding the risk of leakage caused by long-term friction damage to the insulation layer of the cable 2, and effectively extending the service life of the cable 2.

[0024] like Figure 5 As shown, the waterproof mechanism 4 includes a main pipe 401, which is fixedly connected to the inner wall of the charging gun 3. Multiple air jet pipes 402 are fixedly connected to the main pipe 401 in a ring structure. The other end of the air jet pipes 402 extends into the socket of the charging gun 3. One end of the main pipe 401 is fixedly connected to an air guide hose 403. The other end of the air guide hose 403 passes through the inner wall of the cable 2 and extends into the charging pile 1 and is fixedly connected to a pipe connector 404. The pipe connector 404 is fixedly connected to the output end of the air pump 5.

[0025] By incorporating a waterproof mechanism 4 within the charging gun 3, after the charging gun 3 is unplugged, high-pressure air generated by the air pump 5 is ejected from each socket of the charging gun 3 through the jet pipe 402 on the waterproof mechanism 4. In rainy weather, when rainwater flows to the sockets of the charging gun 3, the high-pressure air can form an air curtain in the socket area, reducing the possibility of rainwater directly entering the sockets and effectively preventing electrical faults caused by moisture intrusion. This significantly reduces the risk of electric shock or short circuit and improves user safety during charging operations.

[0026] like Figure 6 As shown, an installation bracket 501 is fixedly connected to the bottom of the air pump 5. The installation bracket 501 is fixedly connected to the inner wall of the charging pile 1. A filter tube 502 is fixedly connected to the installation bracket 501. One end of the filter tube 502 is fixedly connected to a pipe connector 503. The pipe connector 503 is fixedly connected to the input end of the air pump 5. A transmission rack 504 is fixedly connected to the installation bracket 501.

[0027] The filter tube 502 can effectively filter dust, particulate matter and other impurities in the air, preventing impurities from entering the air pump 5 and causing wear, while also preventing impurities from being ejected with high-pressure air and clogging the jet pipe 402.

[0028] like Figure 7 , Figure 8 As shown, an annular groove 601 is provided on the inner wall of the transmission ring 6. A sliding frame 602 is fixedly connected to the transmission ring 6. The other end of the sliding frame 602 extends into the gun port 101 and is fixedly connected to a contact plate 603. The contact plate 603 is slidably engaged with the inner wall of the gun port 101. A plurality of springs 604 are fixedly connected to one side of the contact plate 603. The other end of the springs 604 is fixedly connected to the inner wall of the gun port 101. The other side of the contact plate 603 is in movable contact with the end of the charging gun 3.

[0029] The contact plate 603 is made of rubber with a smooth surface, which will not cause wear when it contacts the end of the charging gun 3. It also has a certain buffering effect. When the charging gun 3 is inserted, the spring 604 is compressed and stores elastic potential energy. When it is pulled out, the elastic potential energy is released, which drives the transmission ring 6 to reset, realizing the reciprocating movement of the transmission ring 6.

[0030] A cleaning ring 605 is slidably fitted at the bottom of the transmission ring 6. A toothed ring 606 is fixedly connected to the outer wall of the cleaning ring 605, and the toothed ring 606 meshes with the transmission rack 504 for transmission. Multiple bristle combs 607 are slidably fitted in a ring structure on the inner wall of the cleaning ring 605. A tension spring 608 is fixedly connected to the outer end of the bristle comb 607, and the other end of the tension spring 608 is fixedly connected to the cleaning ring 605. An arc-shaped block 609 is fixedly connected to the bottom of the transmission ring 6, and one end of the bristle comb 607 slides in contact with the arc-shaped block 609. The arc-shaped block 609 enables the bristle comb 607 to move automatically outward, which can automatically remove the debris wrapped around its outer wall and improve its cleaning effect on the bristles 804.

[0031] like Figure 9 As shown, the transmission mechanism 7 includes a universal joint 701, which is rotatably connected to the sliding frame 602. A drive wheel 702 is fixedly connected to the top of the universal joint 701, and a fixed rack 703 is engaged with one side of the drive wheel 702. One end of the fixed rack 703 is fixedly connected to the mounting frame 501, and a driven wheel 704 is fixedly connected to the bottom of the universal joint 701.

[0032] like Figure 9 As shown, the anti-clogging mechanism 8 includes a rotating ring 801. A limiting ring 802 is fixedly connected to the outer wall of the rotating ring 801. The limiting ring 802 is rotatably connected to the inner wall of the annular groove 601. An annular rack 803 is fixedly connected to the inner wall of the limiting ring 802. The annular rack 803 is meshed with the driven wheel 704 for transmission. Brush bristles 804 are fixedly connected to the inner wall of the rotating ring 801 in an annular structure. The brush bristles 804 are in frictional contact with the outer wall of the filter tube 502.

[0033] The bristles 804 are made of high-density nylon material and are in close contact with the outer wall of the filter tube 502. This effectively cleans the dust and debris attached to the outer wall of the filter tube 502, prevents the filter tube 502 from becoming clogged, and ensures the air intake efficiency of the air pump 5.

[0034] Working principle: When charging is needed, the user pulls the charging gun 3 out of the plug-in port 101. At this time, the compressed spring 604 releases its elastic potential energy, pushing the contact plate 603, the sliding frame 602 and the transmission ring 6 to reset and move. During the movement of the transmission ring 6, the universal joint 701 on the sliding frame 602 drives the driving wheel 702 to roll along the fixed rack 703 and rotate. The driving wheel 702 drives the driven wheel 704 to rotate through the universal joint 701. The driven wheel 704 meshes with the annular rack 803 on the inner wall of the limiting ring 802, driving the rotating ring 801 to rotate. The bristles 804 on the inner wall of the rotating ring 801 rub against the outer wall of the filter tube 502, performing preliminary cleaning on the outer wall of the filter tube 502. At the same time, the transmission ring 6 drives the cleaning ring 605 to move synchronously. The toothed ring 606 on the outer wall of the cleaning ring 605 meshes with the transmission rack 504, causing the cleaning ring 605 to rotate. Under the action of the tension spring 608, the bristle comb 607 cleans the deposits on the bristles 804. When one end of the bristle comb 607 contacts the arc-shaped block 609, the bristle comb 607 moves outward under the action of the arc-shaped block 609, causing the bristle comb 607 to slide on the cleaning ring 605, thereby automatically removing the debris wrapped around the bristle comb 607 and ensuring its cleaning efficiency on the bristles 804. Simultaneously, the insertion and removal of the charging gun 3 triggers the air pump 5 to start. The air pump 5 draws in filtered air through the filter tube 502, generating high-pressure air. The high-pressure air enters the main tube 401 through the pipe connector 404 and the air guide hose 403, and then is ejected from the charging gun 3's socket through multiple jet pipes 402, forming an annular air curtain. If it is raining, the air curtain can effectively prevent rainwater from entering the charging gun 3's socket, while blowing away residual moisture and dust in the socket, preventing moisture intrusion that could cause electrical faults. Meanwhile, the protective ring 201 on the cable 2 keeps the cable 2 suspended off the ground, and the ball bearing 202 reduces wear on the cable 2 when it is dragged, achieving effective protection for the cable 2.
