Description

Technical Field

[0001] This utility model relates to the field of new energy charging gun technology, specifically a shockproof and waterproof new energy charging gun. Background Technology

[0002] In the field of new energy vehicles, the charging gun, as a key interface device connecting charging equipment and electric vehicles, directly affects the safety and convenience of charging. With the increasing popularity of electric vehicles, the technological development and innovation of charging guns have become particularly important. However, existing charging gun technologies still have some shortcomings, especially in terms of impact resistance and waterproofing.

[0003] Existing charging guns often neglect adaptability to complex environments in their design. Especially in rainy and humid climates, the waterproof design of the charging gun is particularly important. When the charging gun is plugged into the charging station to charge the electric vehicle, rainwater can easily flow into the head of the charging gun through gaps and come into contact with the probe. If this is not noticed by the user, it may cause a serious safety accident. In addition, when the user uses brute force to force the insertion, the probe is easily affected by the pushing force, resulting in wear and damage, which is not conducive to long-term charging use. At the same time, during daily storage, the head of the charging gun is easily damaged by collisions with external objects.

[0004] To address the aforementioned issues, this application provides a shockproof and waterproof new energy charging gun. Utility Model Content

[0005] The purpose of this utility model is to provide a shockproof and waterproof new energy charging gun in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A shockproof and waterproof new energy charging gun includes a charging gun body, a sealing component, a first buffer component, and a second buffer component, wherein:

[0008] The charging gun body consists of a gun head and a handle;

[0009] The sealing assembly is mounted on the gun head and is used to seal the gun head during the charging process;

[0010] The first buffer component is used to buffer the insertion force of the gun head;

[0011] The second buffer assembly is used to protect the gun head.

[0012] Furthermore, the sealing assembly includes a mounting plate fixedly sleeved on the gun head, a corrugated sealing ring fixed to one end of the mounting plate, a connecting ring plate fixed to the other end of the sealing ring, and a rubber suction cup fixed to the end of the connecting ring plate facing away from the sealing ring, the rubber suction cup being close to the charging end of the gun head.

[0013] Furthermore, the number of the first buffer components is multiple and they are distributed in a circular array. The first buffer component includes a fixing plate fixed on the inner wall of the connecting ring plate, and a spring located inside the sealing ring is connected between the fixing plate and the mounting plate.

[0014] Furthermore, a guide cylinder is fixed on the mounting plate along the length of the sealing ring, and a guide rod is movably inserted into one end of the guide cylinder facing away from the mounting plate. The other end of the guide rod is fixed to the fixing plate, and the spring is sleeved on the guide cylinder and the guide rod.

[0015] Furthermore, the second buffer assembly comprises two components, which are respectively installed on the outer wall of the mounting plate and the outer wall of the connecting ring plate. Each second buffer assembly includes a protective ring fixed to the outer periphery of the mounting plate or the outer periphery of the connecting ring plate. The outer periphery of the protective ring is provided with a plurality of evenly distributed buffer portions, wherein:

[0016] The buffer section includes a movable arc-shaped protective plate, and a spring is connected between the open side of the arc-shaped protective plate and the outer side of the protective ring.

[0017] Furthermore, a guide cylinder two is fixed on the outer side of the protective ring, and a guide rod two is movably inserted into one end of the guide cylinder two facing away from the protective ring. The other end of the guide rod two is fixed to the opening side of the arc-shaped protective plate, and the spring two is sleeved on the guide cylinder two and the guide rod two.

[0018] Furthermore, a cushioning air cushion is installed on the side of the arc-shaped protective plate facing away from the opening.

[0019] Furthermore, several buffer sections on the two protective rings are staggered.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This solution significantly improves the waterproofing capability of the charging gun in rainy and humid climates through the design of the sealing components, especially the application of corrugated sealing rings and rubber suction cups. It effectively prevents rainwater from flowing into the gun head, reducing safety accidents caused by liquid contact with the probe. Since the probe is effectively sealed during the charging process, the risk of short circuits and electric shocks caused by environmental factors is reduced, thus improving the safety of the charging process.

[0022] The design of the first and second buffer components in this solution reduces the wear on the probe when inserting and removing the charging gun, as well as the physical damage to the gun head during daily use and storage, thus extending the service life of the charging gun. The design of the first and second buffer components allows the charging gun to withstand greater external impacts without being damaged, especially when it is forcibly inserted with brute force when the charging socket is not aligned.

[0023] The spring in this design not only reduces wear on the probe when inserting and removing the charging gun, but also ensures that the rubber suction cup is stably attached to the charging station, protecting the charging process. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] This application provides a collision-proof and waterproof new energy charging gun, mainly to address the problem that existing charging guns often neglect adaptability to complex environments in their design. Especially in rainy and humid climates, the waterproof design of the charging gun is particularly important. When the charging gun is plugged into a charging station to charge an electric vehicle, rainwater can easily seep into the head of the charging gun through gaps and come into contact with the probe. If this is not noticed by the user, it may cause a serious safety accident. Furthermore, when the user forcibly inserts the charging gun, the probe is easily affected by the pushing force, resulting in wear and damage, which is not conducive to long-term charging use. Additionally, during daily storage, the head of the charging gun is easily damaged by collisions with external objects. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0031] A shockproof and waterproof new energy charging gun mainly includes a charging gun body 1, a sealing component 2, a first buffer component 3, and a second buffer component 4, wherein:

[0032] The charging gun body 1 consists of a gun head 11 and a handle 12. The gun head 11 is the key part for charging contact, while the handle 12 provides a convenient grip structure for the user.

[0033] The sealing assembly 2 is installed on the gun head 11 and is used to seal the gun head 11 during the charging process to prevent liquid intrusion.

[0034] The first buffer component 3 is used to buffer the insertion force of the gun head 11, reducing probe damage caused by brute force insertion;

[0035] The second buffer assembly 4 is used to protect the gun head 11 and prevent damage caused by collisions during daily storage.

[0036] In this novel anti-collision and waterproof new energy charging gun, the design of the sealing component 2 is crucial. Its ingenious structure aims to ensure the sealing of the gun head 11 during the charging process, preventing the intrusion of moisture and impurities. Specifically, please refer to... Figure 2 and Figure 4 The sealing assembly 2 includes a mounting plate 21 fixedly sleeved on the gun head 11, which serves to connect and fix subsequent components. A corrugated sealing ring 22 is fixed on one end of the mounting plate 21. This corrugated design increases the elasticity of the sealing ring 22, enabling it to adapt to different environmental conditions and pressure changes, thereby providing a more reliable sealing effect. A connecting ring plate 23 is fixed on the other end of the sealing ring 22. A rubber suction cup 24 is fixed on the end of the connecting ring plate 23 facing away from the sealing ring 22. The rubber suction cup 24 is close to the charging end of the gun head 11. When the gun head 11 is inserted into the charging interface, it can be adsorbed onto the charging pile by the adsorption force of the rubber suction cup 24, increasing the sealing between the gun head 11 and the charging interface, and further preventing the intrusion of moisture and impurities.

[0037] Overall, the sealing component 2, through this structural design, not only enhances the waterproof performance of the charging gun in rainy and humid environments, but also improves the safety and reliability of the charging gun. This design reflects a deep consideration of the environmental factors that the charging gun may encounter during use, ensuring that the charging gun can maintain its performance even in harsh environments, protecting the internal circuitry from damage, thereby extending the service life of the charging gun and reducing maintenance costs.

[0038] In this impact-resistant and waterproof new energy charging gun, the design of the first buffer component 3 reflects a meticulous design for the impact forces that the charging gun may encounter during use. Specifically, please refer to... Figure 2 and Figure 4 The first buffer assembly 3 is multiple and arranged in a circular array to ensure the uniformity of force. The first buffer assembly 3 includes a fixing plate 31 fixed on the inner wall of the connecting ring plate 23. A spring 32 located inside the sealing ring 22 is connected between the fixing plate 31 and the mounting plate 21. The design of the spring 32 allows it to deform when subjected to external impact, thereby absorbing the impact force and reducing damage to the internal structure of the gun head 11.

[0039] Furthermore, a guide cylinder 33 is fixed on the mounting plate 21 along the length of the sealing ring 22. A guide rod 34 is movably inserted into one end of the guide cylinder 33 facing away from the mounting plate 21. The other end of the guide rod 34 is fixed to the fixing plate 31. A spring 32 is sleeved on the guide cylinder 33 and the guide rod 34. This design provides precise guidance for the movement of the spring 32, ensuring that the direction of the buffer force transmission is correct and avoiding additional wear caused by deviation. At the same time, it enhances the flexibility and response speed of the first buffer assembly 3. The spring 32 sleeved on the guide cylinder 33 and the guide rod 34 allows the spring 32 to quickly return to its original shape when compressed or stretched, thus improving the buffer efficiency.

[0040] Meanwhile, under the elastic force of multiple springs 32, the rubber suction cup 24 can be stably attached to the charging pile, improving the sealing performance;

[0041] The design of the first buffer component 3 not only improves the durability and reliability of the charging gun, but also optimizes the user experience during the charging process. Through precise structural design and material selection, this solution ensures the stability and safety of the charging gun during insertion and removal, reduces the risk of damage caused by improper operation or external impact, thereby extending the service life of the charging gun and reducing maintenance costs.

[0042] Furthermore, please refer to Figure 2 , Figure 3 and Figure 4Two second buffer assemblies 4 are installed on the outer side wall of the mounting plate 21 and the outer side wall of the connecting ring plate 23, respectively, ensuring that the gun head 11 is effectively protected in all directions. The second buffer assembly 4 includes a protective ring 41 fixed on the outer periphery of the mounting plate 21 or the outer periphery of the connecting ring plate 23. Several evenly distributed buffer parts are installed on the outer periphery of the protective ring 41. This evenly distributed design allows the protective ring 41 to absorb and disperse the impact force evenly in all directions, thereby protecting the gun head 11 from damage.

[0043] The buffer section includes a movable arc-shaped protective plate 42. This arc-shaped design helps to absorb energy through deformation when subjected to impact, reducing the direct impact on the gun head 11. A spring 43 is connected between the open side of the arc-shaped protective plate 42 and the outer side of the protective ring 41. The design of the spring 43 allows the arc-shaped protective plate 42 to make appropriate displacement when subjected to external force, and can quickly return to its original shape after the impact force disappears, maintaining the structural stability of the gun head 11.

[0044] A guide cylinder 44 is fixed on the outer side of the protective ring 41. A guide rod 45 is movably inserted into the end of the guide cylinder 44 facing away from the protective ring 41. The other end of the guide rod 45 is fixed to the opening side of the arc-shaped protective plate 42. A spring 43 is sleeved on the guide cylinder 44 and the guide rod 45, providing precise guidance for the movement of the arc-shaped protective plate 42, ensuring that the buffer part can effectively deform along the predetermined direction when it is impacted, and improving the service life of the spring 43.

[0045] The design of the second buffer component 4 not only enhances the charging gun's impact resistance but also improves its stability and reliability under external impact. Through precise structural design and material selection, this solution ensures the safety and durability of the charging gun in various usage environments, reduces the risk of damage caused by collisions with foreign objects, thereby extending the service life of the charging gun and reducing maintenance costs. This design reflects a deep understanding and comprehensive consideration of various situations that the charging gun may encounter during use, showcasing an innovative solution to meet the high safety and high reliability requirements of the new energy vehicle charging field.

[0046] In the anti-collision and waterproof new energy charging gun of this utility model, the design of the arc-shaped protective plate 42 further enhances the protective performance of the second buffer component 4. For details, please refer to... Figure 3 and Figure 4A buffer air cushion 46 is installed on the side of the arc-shaped protective plate 42 facing away from the opening. This ingenious design provides an additional protective layer for the gun head 11. The buffer air cushion 46 can further reduce the impact of the remaining impact force on the charging gun head 11. The design of the buffer air cushion 46 allows the force to be dispersed and absorbed by deformation when impacted, thereby greatly reducing the possibility of the impact force being directly transmitted to the gun head 11 and protecting the sensitive internal charging interface and circuit.

[0047] In addition, the several buffer sections on the two protective rings 41 are staggered. This layout not only provides all-round protection, but also ensures that impacts in any direction can be effectively absorbed and dispersed. The staggered buffer sections can work independently at different impact angles without interfering with each other. This design improves the efficiency and effectiveness of the entire buffer system. Each buffer section can provide maximum protection in its corresponding direction, without causing insufficient protection in some directions due to an overly concentrated layout.

[0048] When using this charging gun:

[0049] Align the gun head 11 with the interface on the charging pile, move the gun head 11, and the probe of the gun head 11 will be inserted into the interface. Then the rubber suction cup 24 will adhere to the charging pile. At the same time, the spring 32 will provide cushioning to reduce damage to the internal structure of the gun head 11.

[0050] When the gun head 11 is fully inserted into the interface, under the elastic force of the spring 32, the rubber suction cup 24 is tightly attached to the charging pile, forming a seal to prevent the intrusion of moisture and impurities.

[0051] When the gun head 11 is hit by an external object, the buffer air cushion 46 and the second spring 43 will buffer the force and protect the gun head 11.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
