Description

Technical Field

[0001] This utility model belongs to the field of charging gun technology, and specifically relates to an anti-slip structure for charging gun grips. Background Technology

[0002] In the popularization of new energy vehicles, portable charging guns, as core accessories for home and emergency charging scenarios, directly impact user experience in terms of ease of use and safety. Currently, most mainstream portable charging guns use smooth plastic or simple textured handles, prioritizing ease of injection molding over adequate anti-slip properties in different usage scenarios. In daily use, the operator's hand condition (e.g., sweat, oil) and environmental factors (dry, stiff hands in low temperatures, damp hands in rainy weather) significantly reduce the friction between the handle and the palm. For example, during summer charging, the operator's palms are prone to sweating due to heat, reducing the coefficient of friction of a smooth handle surface from the usual 0.6 to below 0.2. If there is resistance when plugging or unplugging the charging gun into the vehicle's charging port, or if the cable's weight creates a downward pull, the handle can easily slip out of the hand.

[0003] More importantly, when the charging gun slips from the operator's hand, it typically falls from a height of 0.8-1.5 meters (a height that is consistent with the gripping habits of adults). The impact force is concentrated at the connection between the handle and the plug. This area is both a stress concentration point for the cable and a weak point for the internal terminals, which can easily lead to loosening of the cable interface, deformation of the terminals, or even poor contact in the internal circuit. If the plug hits the ground downwards during the fall, it may also cause the plug shell to crack and the metal contacts to be exposed, which not only directly damages the charging gun but also poses a risk of leakage during subsequent use, threatening the personal safety of the user. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-slip structure for the charging gun grip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a charging gun grip anti-slip structure, including a charging gun body, an anti-slip groove is provided at one end of the charging gun body, and symmetrical side mounting parts are fixedly installed at one end of the charging gun body. A rope is provided at the top of the charging gun body, and both ends of the rope pass through to the bottom of the side mounting parts. A contact layer is fixedly adhered to one side inside the side mounting parts.

[0006] The side mounting component has an abutment on the other side inside. One side of the abutment contacts an elastic element. Both ends of the abutment have side rods that extend to the outside of the side mounting component. The side mounting component has a button on its outside.

[0007] Preferably, one side of the side mounting member has a mounting arc surface that matches the curvature of the charging gun body surface.

[0008] Preferably, the side mounting member has an embedding cavity on its inner side, which is used to embed the contact layer, and the contact layer is in contact with the outer side of the rope.

[0009] Preferably, an abutment layer is fixedly adhered to the other side of the abutment member, and the abutment layer is in contact with the inner side of the rope.

[0010] Preferably, the elastic element is made of shape memory alloy, and both ends of the elastic element are fixedly installed with connectors, which are fixedly connected to the inner side of the side mounting component.

[0011] Preferably, side blocks are fixedly installed at both ends of the abutment member, and the side blocks are fixedly connected to the side rod.

[0012] Preferably, a trapezoidal block is fixedly installed at one end of the side rod, and the trapezoidal block and the button are fixedly connected to each other.

[0013] Preferably, both ends of the rope are fixedly installed with limiting end blocks located at the bottom of the side mounting component.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. When handling the charging gun, fingers can naturally rest and embed into the anti-slip grooves on the grip surface. The cord naturally wraps around the operator's wrist, forming a dual protective structure of hand grip and wrist restraint. The anti-slip grooves enhance the stability of the fit between the palm and the charging gun, while the cord limits the displacement of the charging gun relative to the wrist, significantly improving the reliability of the connection between the operator and the charging gun. This effectively avoids the risk of slippage due to hand slippage or accidental force during insertion, removal, or movement, providing dual protection for the safety and stability of the charging operation.

[0016] 2. During use, the rope is flexibly adjustable to accommodate users with different hand sizes and body shapes. Whether it's the initial contact with the charging gun to connect to the vehicle or the subsequent removal and return to the charging station after charging, it provides a comfortable grip that fits the user's hand shape, significantly improving comfort and usability during new energy vehicle charging. When the charging gun is still plugged into the charging station and idle, the operator can roughly adjust the cavity size between the rope and the charging gun according to their body shape and hand size. This design prevents people with wider hands from experiencing discomfort due to excessive rope constriction, while also preventing people with smaller hands from easily slipping out of the space created by the rope due to an excessively large cavity. This effectively broadens the applicable user range of this anti-slip structure, improves the product's compatibility and adaptability for users with different hand sizes, and allows all types of people to have a comfortable and safe grip experience.

[0017] 3. During use, the trapezoidal block serves as the connecting medium between the side rod and the button. Its special trapezoidal structure effectively disperses the external force on the side rod, expands the stress-bearing area, and reduces local stress concentration, thereby reducing the risk of deformation or bending of the side rod under frequent stress and extending the service life of the component. Simultaneously, the limiting end blocks at both ends of the rope have an outer diameter larger than the diameter of the rope channel inside the side mounting component, forming a physical barrier that completely prevents the rope from slipping out of the side mounting component during use, ensuring the stable operation of the anti-slip structure.

[0031] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0032] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0033] Example:

[0034] refer to Figures 1-4 The anti-slip structure of the charging gun grip includes a charging gun body 1, an anti-slip groove 101 at one end of the charging gun body 1, a symmetrical side mounting piece 2 fixedly installed at one end of the charging gun body 1, a rope 3 at the top of the charging gun body 1, both ends of the rope 3 passing through to the bottom of the side mounting piece 2, and a contact layer 4 fixedly adhered to one side inside the side mounting piece 2.

[0035] The side mounting component 2 has an abutting component 5 on the other side inside. One side of the abutting component 5 contacts an elastic component 6. Both ends of the abutting component 5 have side rods 702 that extend to the outside of the side mounting component 2. The side mounting component 2 has a button component 7 on its outside.

[0036] Specifically, when using the charging gun body 1, fingers can naturally fit into the anti-slip grooves 101 on the grip surface, while the rope 3 naturally wraps around the operator's wrist during the gripping process, forming a dual protective structure of hand grip and wrist restraint. The anti-slip grooves 101 enhance the stability of the fit between the palm and the charging gun body 1, while the rope 3 limits the displacement of the charging gun body 1 relative to the wrist, significantly improving the reliability of the connection between the operator and the charging gun body 1. This effectively avoids the risk of the charging gun body 1 slipping off due to hand slippage or accidental force during insertion, removal, and movement, providing dual protection for the safety and stability of the charging operation.

[0037] The side mounting component 2 has a mounting arc surface 201 on one side, which matches the curvature of the surface of the charging gun body 1.

[0038] Specifically, the curvature of the mounting arc surface 201 precisely matches the curvature of the outer surface of the charging gun body 1, which can increase the contact area between the side mounting part 2 and the charging gun body 1 and reduce the gap between them; at the same time, it makes the side mounting part 2 fit tightly against the surface of the charging gun body 1, avoiding local stress concentration caused by poor fit, thereby significantly improving the overall connection between the side mounting part 2 and the charging gun body 1.

[0039] The side mounting component 2 has an embedded cavity 401 on its inner side. The embedded cavity 401 is fitted into the contact layer 4 for internal installation. The contact layer 4 is in contact with the outer side of the rope body 3. The other side of the abutment component 5 is fixedly bonded with an abutment layer 501, which is in contact with the inner side of the rope body 3.

[0040] Specifically, the contact layer 4 and the abutment layer 501 form a bidirectional wrapping contact from the outside and inside of the rope body 3, respectively. This double-pinch contact method can significantly increase the contact area between the rope body 3 and the inside of the side mounting component 2. At the same time, through the pressure transmission of the double contact surfaces, the friction of the rope body 3 inside the side mounting component 2 is significantly improved, effectively preventing the rope body 3 from sliding. Among them, the embedded cavity 401 pre-set on the inside of the side mounting component 2 is precisely matched with the outer dimensions of the contact layer 4, which can realize the embedded installation of the contact layer 4, ensuring the structural stability of the contact layer 4 after assembly, and preventing its positional displacement due to external force.

[0041] The elastic element 6 is made of shape memory alloy. Both ends of the elastic element 6 are fixedly installed with connectors 601. The connectors 601 are fixedly connected to the inner side of the side mounting part 2. Both ends of the abutting part 5 are fixedly installed with side blocks 701. The side blocks 701 are fixedly connected to the side rod 702. One end of the side rod 702 is fixedly installed with a trapezoidal block 703. The trapezoidal block 703 is fixedly connected to the button part 7. Both ends of the rope body 3 are fixedly installed with limiting end blocks 8 located at the bottom of the side mounting part 2.

[0042] Specifically, when button 7 is pressed, it will drive side rod 702, side block 701 and abutment 5 to move synchronously along a preset trajectory. During this process, the displacement of abutment 5 will form a stable compression on elastic element 6. The shape memory alloy material of elastic element 6, with its excellent shape memory characteristics, can quickly trigger the rebound action after being compressed and deformed, pushing abutment 5 and button 7 back to the initial working position.

[0043] Furthermore, the trapezoidal block 703, serving as the connecting medium between the side rod 702 and the button component 7, effectively disperses the external force on the side rod 702 due to its special trapezoidal structure, expands the stress-bearing area, and reduces local stress concentration. This reduces the risk of deformation or bending of the side rod 702 under frequent stress, extending the service life of the component. Simultaneously, the limiting end blocks 8 at both ends of the rope 3 prevent the rope 3 from slipping out of the side mounting component 2 during use, ensuring the stable operation of the anti-slip structure.

[0044] The working principle of this utility model is as follows: When using the charging gun body 1, the palm needs to be inserted into the fitting cavity formed between the top of the charging gun body 1 and the rope 3, while holding the gripping end of the charging gun body 1. At this time, the fingers can naturally fit and embed into the anti-slip groove 101 on the surface of the grip. The physical fit between the fingers and the anti-slip groove 101 increases the grip friction, initially achieving an anti-slip effect during the use of the charging gun body 1. During the gripping process, the rope 3 will naturally wrap around the operator's wrist, forming a dual protective structure of hand grip and wrist restraint, which works synergistically with the anti-slip groove 101 to provide anti-slip protection. The anti-slip groove 101 enhances the stability of the fit between the palm and the charging gun body 1, while the rope 3 limits the displacement of the charging gun body 1 relative to the wrist, greatly improving the connection reliability between the operator and the charging gun body 1. This effectively avoids the risk of slippage caused by hand slippage or accidental force during use scenarios such as plugging, unplugging, and moving the charging gun body 1, providing dual protection for the safety and stability of the charging operation.

[0045] Meanwhile, the rope 3 is adaptable to different users, providing a more suitable and comfortable user experience when picking up and dropping the charging gun 1 during charging. When the charging gun 1 is still plugged into the charging pile and not in use, the operator can roughly adjust the size of the cavity between the rope 3 and the charging gun 1 according to their body size and hand size. By pressing the button 7, the side rod 702, side block 701 and abutment 5 move synchronously along the preset trajectory. During this process, the abutment 5 will form a stable compression on the elastic element 6. The elastic element 6, due to its own elasticity, will trigger a rebound action after being compressed and deformed, ensuring that the abutment 5 and the button 7 are accurately reset to the initial working position. At the same time, the movement of the abutment 5 will cause the abutment layer 501 to detach from the contact with the inside of the rope 3. At this time, the rope 3 loses the bidirectional clamping force, is in a natural vertical state and separates from the contact layer 4. The operator can easily push the rope 3 to move and stretch inside the side mounting part 2, thereby flexibly adjusting the size of the cavity between the rope 3 and the charging gun 1.
