Description

Technical Field

[0001] The present invention relates to the technical field of charging equipment, and in particular to an intelligent protective charging pile. Background Art

[0002] The intelligent protection charging pile is a new type of charging equipment that integrates advanced technology and innovative design. It has multiple protection functions. First of all, in terms of mechanical structure, it has a sturdy and durable shell that can effectively resist external impact and collision, and prevent damage to internal key components due to accidental impact. Its charging plug adopts an automatic telescopic design, which retracts when not charging, avoiding the plug from being exposed to pollution and damage, and extending its service life. The waterproof and dustproof sealing structure uses special sealing rings and sealing grooves to ensure that the charging pile can still operate safely and stably under various severe weather conditions, such as heavy rain and sandstorm environments, reducing the risk of failure caused by water and dust entering. In addition, the intelligent protection charging pile is also equipped with an intelligent temperature adjustment system, which can automatically start the fan or heating device according to the internal temperature, always maintain a suitable working temperature, and ensure charging efficiency and equipment reliability. At the same time, it also has a complete safety protection mechanism, such as anti-leakage protection mechanism, automatic fire extinguishing device, etc. When an emergency such as leakage or fire occurs, it can respond quickly and take measures to maximize the safety of users and equipment. This intelligent protection charging pile provides strong support for the popularization and convenient use of electric vehicles.

[0003] When the existing mechanical seal is installed and used, the charging head of the intelligent protection charging pile is in use. When the user is plugging and unplugging the charging head, if the charging head is not held firmly, the charging head may accidentally fall to the ground, which may cause the precise circuit components and connection structures in the charging head. The impact force generated by the fall may cause the internal electronic components to loosen, shift or even be damaged, which will directly affect the normal use function of the charging head at the moment, resulting in poor charging contact, inability to charge normally and other problems, and may also bury safety hazards for the subsequent charging process, such as causing short circuits, leakage and other dangerous situations. In addition, during the long-term use of the charging head, dust, dirt and other debris are easily accumulated on its surface and interface. These impurities not only affect the appearance of the charging head, but more importantly, they may affect the good contact between the charging head and the charging device interface, reducing the charging efficiency. Moreover, if dust and other impurities enter the tiny gaps inside the charging head, it may also damage its internal circuit, affecting its service life and performance stability, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose an intelligent protection charging pile. Summary of the invention

[0015] Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the present invention, when the charging device falls, the limit slider is pushed by the first return spring, and the first buffer spring, the first torsion spring buckle and the protective outer plate and other components work together to absorb and disperse the impact force, so as to protect key components such as the charging handle and the telescopic charging head, reduce the risk of physical damage caused by falling impact, reduce the frequency of equipment maintenance and replacement, thereby reducing costs, and at the same time, it can also ensure charging safety, prevent dangerous situations such as leakage and short circuit caused by equipment damage, and ensure the normal use of the charging device and the safety of users.

[0018] 2. In the present invention, the sealing protection structure can prevent moisture from entering the key parts of the charging device, and can prevent rainwater from penetrating and damaging internal components on rainy days, ensuring that the device works normally in a humid environment; it can prevent dust and impurities from entering the interior of the charging device, keep the interior of the device clean, extend the service life of electronic components, reduce the trouble of cleaning and maintenance, improve charging stability and reliability, ensure a smooth charging process, and provide users with efficient and safe charging services.

[0019] 3. In the present invention, the clamping and cleaning structure plays a key role in the charging process. The clamping function can ensure that the charging handle is firmly connected to the charging stand, prevent the charging connection from loosening or being interrupted due to external force in a complex environment, ensure the continuity and stability of charging, avoid the trouble of re-plugging the charging head, and improve the charging efficiency. The cleaning function automatically cleans impurities on the surface of the telescopic charging head through the cleaning head to ensure good contact of the charging interface, reduce the risk of increasing the charging resistance due to impurities affecting the charging efficiency and damaging the equipment, improve the charging efficiency and quality, reduce the risk of equipment failure, and extend the service life of the equipment. Its automation function also reduces the need for human intervention and reduces the user's operating safety risks.

[0020] 4. In the present invention, the power-saving and heat-dissipating structure helps the charging equipment to operate efficiently and save energy and reduce emissions. In terms of power saving, by adjusting the angle of the solar panel to fully receive solar energy and convert it into electrical energy, the dependence on traditional power grid electricity can be reduced, and energy consumption and costs can be reduced. For example, charging piles in open-air parking lots can use solar energy to charge electric vehicles, saving user costs and helping environmental protection, alleviating the impact of power supply. In terms of heat dissipation, the cooling fan pays attention to the temperature changes inside the charging pile. The electronic components generate heat during charging, and the cooling fan can quickly dissipate heat to maintain the appropriate operating temperature of the equipment, ensure stable operation, and avoid excessive temperature affecting equipment performance and life and causing safety accidents. Good heat dissipation can also extend the service life of electronic components, reduce the frequency of equipment maintenance and replacement, and provide long-term reliable charging services.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] Embodiment 1, as Figure 1 - Figure 6 As shown, in this intelligent protective charging pile, the charging pile 1 is used as the main structure to carry various components. The display screen 101 in the middle of the front side of the charging pile 1 is used to display charging-related information. The heat dissipation holes 102 on both sides help the device to dissipate heat. When charging is required, the power port 103 is connected to the charging handle 25 through the power conduit 24. The retractable charging head 104 on the charging handle 25 is used to connect to the device to be charged. The first servo motor 21 drives the winding reel 23 to rotate, thereby retracting and releasing the power conduit 24.

[0042] When the charging handle 25 is accidentally subjected to external force and may fall and hit the ground, the outer protective plate 215 will first contact the ground to hit the protective plate 215. When the protective plate 215 is hit, the impact force will be transmitted to the rotating telescopic rod 211, causing the rotating telescopic rod 211 to deflect to one side to reduce the force generated by the collision. Then, when the rotating telescopic rod 211 is deflected, the buffer sleeve 212 slides on the buffer ring 216, and then the sliding of the buffer sleeve 212 is used to stretch the rotating telescopic rod 211. Since the first buffer spring 214 is provided on the opposite side of the rotating telescopic rod 211, the impact force is transmitted to the rotating telescopic rod 211 when it is deflected. During the process, the first buffer spring 214 is transmitted to the first buffer spring 214 to further reduce the impact force. At the same time, the first return spring 27 in the limiting groove 26 on the outer wall of one side of the charging handle 25 will push the protective outer ring 29 through the limiting slider 28. The rotating telescopic rod 211 on the mounting sleeve 210 between adjacent protective outer rings 29 will drive the buffer sleeve 212 to move. While the buffer sleeve 212 slides on the buffer ring 216, on the one hand, the first torsion spring buckle 213 will adaptively rotate, and on the other hand, the first buffer spring 214 on one side of the buffer sleeve 212 will be compressed to absorb the impact force. The protective outer plate 215 will also cooperate to buffer the external force impact under the action of the first torsion spring buckle 213.

[0043] Embodiment 2, as Figure 5 - Figure 7As shown, when a sealing protection operation is required, the second servo motor 31 is started, and the second servo motor 31 drives the first cylindrical gear 32 at the output shaft end to rotate. The rotation of the first cylindrical gear 32 causes the first rack 33 meshing therewith to move, thereby pushing the movable turntable 34 on one side of the first rack 33 to move. Several arc grooves 37 opened on the outer wall of the movable turntable 34 change their positions with the movement of the movable turntable 34. The sliding rod 38 in the arc groove 37 slides along its trajectory driven by the arc groove 37, and the sealing block 35 connected to one end of the sliding rod 38 close to the charging pile 1 also moves accordingly. Since the sliding trajectory of the sealing block 35 changes with the change of the arc groove 37, multiple sealing blocks 35 cooperate with each other and gather or disperse from different directions toward the center position of the mounting shell 36 at the front end of the charging handle 25, thereby realizing the operation of sealing or releasing the sealing state of the gap between the charging handle 25 and the mounting shell 36, thereby achieving the effect of sealing protection.

[0044] Embodiment three, as Figure 8 - Fig.11 As shown, when the charging handle 25 is inserted into the movable chamber 41 of the charging pile 1, the charging handle 25 pushes the movable rod 44 to move into the movable chamber 41, and the movable rod 44 drives the long plate 45 to move, compressing the second return spring 46 to store force. While the long plate 45 moves, it drives the auxiliary rod 48 to move, and the auxiliary rod 48 slides on the outer wall of the first rotating frame 49, pushing the first rotating frame 49 to rotate a certain angle. At the same time, the second buffer spring 416 inside the movable rod 44 pushes the deflection rod 417 to move outward, so that the cleaning head 420 contacts the telescopic charging head 104. During the movement of the deflection rod 417, the pin 419 slides in the external embedded groove 418 to play a limiting and guiding role, and the second rack 421 of the cleaning head 420 drives the second cylindrical gear 422 to rotate, and the second cylindrical gear 422 then The clamping block 423 is driven to move to clamp and fix the charging handle 25. When the charging handle 25 needs to be taken out, the charging handle 25 is pulled outward, and the long plate 45 is reset under the elastic force of the second reset spring 46. The auxiliary rod 48 slides in the opposite direction to drive the first rotating frame 49 to reverse. The ratchet groove 411 on the first rotating frame 49 pushes the boosting tooth 412 to rotate, and the boosting tooth 412 drives the clamping rod 414 to move through the reset torsion spring 413. At the same time, the boosting tooth 412 itself rotates a certain angle to disengage from the ratchet groove 411 to prepare for the next insertion of the charging handle 25. The movable rod 44 is reset under the drive of the long plate 45. At the same time, the deflection rod 417 is retracted under the drive of the movable rod 44, and the cleaning head 420 is disengaged from the contact with the telescopic charging head 104, and the clamping block 423 also releases the charging handle 25.

[0045] Embodiment 4, as Fig.12 - Fig.14As shown, the third servo motor 51 is started, and the third servo motor 51 drives the third cylindrical gear 52 at the output shaft end to rotate. The rotation of the third cylindrical gear 52 drives the first sliding frame 53 and the second sliding frame 54 meshed with it to move. Since the third cylindrical gear 52 is located in the middle position, the first sliding frame 53 and the second sliding frame 54 on both sides thereof will make relative or contradictory movements. At this time, the third buffer spring 55 between the two plays a role of buffering and auxiliary reset. When the first sliding frame 53 and the second sliding frame 54 move, the third rack 56 on the side away from them also moves accordingly, thereby driving the fourth rack 56 meshed with them. The column gear 57 rotates, and the fourth cylindrical gear 57 drives the rotating frame 59 to rotate through the mounting rod 58, thereby adjusting the angle of the solar panel 510 in the middle of the rotating frame 59, so that it can better receive solar energy, convert solar energy into electrical energy for storage or directly use it for partial power supply of the charging pile, so as to achieve the purpose of saving electricity. At the same time, the two cooling fans 512 on the side of the charging pile 1 close to the dustproof plate 511 are started, and airflow is generated by rotation, which accelerates the air flow inside the charging pile 1, quickly dissipates the heat, plays a role in heat dissipation and cooling, and ensures that the electronic components inside the charging pile work in a suitable temperature environment.

[0046] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
