Description

Technical Field

[0001] This utility model relates to the field of charging gun technology, specifically a charging gun tail fixing structure. Background Technology

[0002] Currently, with the widespread adoption of electric vehicles, the demand for charging infrastructure is surging. As a critical interface, the convenience and safety of daily storage and management of charging guns are receiving increasing attention. Most charging gun holders on the market are of fixed sizes, only compatible with specific models or size ranges of charging guns.

[0003] Currently, charging guns of different brands, models, and power levels vary significantly in diameter, length, weight, and handle shape. The standardized bracket design in existing technology often requires users to frequently change brackets or use incompatible fixing methods when faced with diverse charging guns. This is not only cumbersome but also poses a risk of the charging gun not being securely fixed, slipping, or tipping over. Utility Model Content

[0004] The purpose of this utility model is to provide a charging gun tail fixing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a charging gun tail fixing structure, including a base and a sleeve, the sleeve being slidably installed inside the base, a mounting seat being fixedly installed on the sleeve, a fixing seat being fixedly installed below the mounting seat, three sets of annularly distributed guide rails being fixedly installed inside the mounting seat, an adjusting frame being slidably installed inside each of the three sets of guide rails, an adjusting rod being fixedly installed on each of the three sets of adjusting frames, an adjusting disc being rotatably installed inside the mounting seat, a first toothed ring being sleeved on the adjusting disc, a rack being slidably installed inside the mounting seat, the rack being meshed with the first toothed ring, three sets of annularly distributed adjusting grooves being opened on the adjusting disc, the three sets of adjusting grooves being correspondingly arranged with the three sets of adjusting frames, and the three sets of adjusting rods being slidably connected to the adjusting disc through the corresponding adjusting grooves.

[0006] As a further preferred embodiment of this technical solution, a circulating air pump is fixedly installed inside the mounting base, and a cylinder is fixedly installed inside the mounting base. The rack is fixedly connected to the output end of the cylinder piston rod. The air outlet of the circulating air pump is connected to the air inlet of the cylinder through a high-pressure air pipe, and the air outlet of the cylinder is connected to the air inlet of the circulating air pump through a purification pipeline.

[0007] As a further preferred embodiment of this technical solution, an installation ring is rotatably installed inside the fixed base, and a second toothed ring is sleeved on the installation ring. The fixed base is provided with multiple sets of annularly distributed limiting plates, and the multiple sets of limiting plates are rotatably connected to the fixed base through an installation shaft.

[0008] As a further preferred embodiment of this technical solution, multiple sets of mounting shafts are distributed in a ring around the mounting ring, and gears are sleeved on each set of mounting shafts, with each set of gears meshing with the second gear ring.

[0009] As a further preferred embodiment of this technical solution, two sets of cross-distributed brackets are provided between the sleeve and the base. The upper ends of the two sets of brackets are rotatably connected to the sleeve via a rotating shaft, and a slider is rotatably installed at the lower end of the bracket. A sliding rod is fixedly installed inside the base.

[0010] As a further preferred embodiment of this technical solution, the slider is slidably connected to the base, the slider is slidably sleeved with the slide rod, and two sets of symmetrically distributed first springs are sleeved on the slide rod, with the two ends of the first springs being fixedly connected to the slider and the base, respectively.

[0011] As a further preferred embodiment of this technical solution, a damper is fixedly installed between the slider and the base, and a second spring is sleeved on the damper.

[0012] This utility model provides a charging gun tail fixing structure, which has the following beneficial effects:

[0013] (1) This utility model, through the design of three sets of synchronously radially movable adjustment frames, can firmly clamp the tail of charging guns of different brands, models and diameters, effectively overcoming the problem that a single bracket cannot be compatible with various gun types. At the same time, multiple sets of synchronously converged limiting plates in the fixed base can flexibly adapt to and stably constrain charging connection cables of different thicknesses. With the rack and pinion transmission mechanism driven by the circulating air pump and cylinder, the opening and closing action of the adjustment frame is automated and precisely controlled, making the operation of adapting to different charging guns more convenient, efficient and stable, greatly reducing the risk of slippage or tipping due to mismatched fixing, and improving the safety and user experience.

[0014] (2) This utility model uses a cross bracket to connect the sleeve and the base, and with the cooperation of the slider, the slide rod, the first spring, the second spring and the damper, it forms a highly efficient multi-level buffer system. This design can effectively absorb and dissipate the energy generated by the vibration, impact and accidental pulling from the charging gun body and its connecting cable. The first and second springs provide elastic support and restoring force, while the damper effectively suppresses the reciprocating oscillation of the spring and quickly attenuates the vibration. Together, they ensure that the charging gun remains stable in a fixed state, prevent displacement, loosening or even falling damage caused by external interference or vibration of the equipment itself, and extend the service life of the equipment.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, a charging gun tail fixing structure includes a base 1 and a sleeve 2. The sleeve 2 is slidably installed inside the base 1. A mounting seat 3 is fixedly installed on the sleeve 2, and a fixing seat 4 is fixedly installed below the mounting seat 3. Three sets of annularly distributed guide rails 5 are fixedly installed inside the mounting seat 3. Adjusting brackets 6 are slidably installed inside each of the three sets of guide rails 5. Adjusting rods 7 are fixedly installed on each of the three sets of adjusting brackets 6. An adjusting disc 8 is rotatably installed inside the mounting seat 3. A first toothed ring 9 is sleeved on the adjusting disc 8. A rack 10 is slidably installed inside the mounting seat 3. The rack 10 meshes with the first toothed ring 9. Three annular... The system includes three sets of adjustment slots 13, each corresponding to one of three sets of adjustment frames 6. Three sets of adjustment rods 7 are slidably connected to the adjustment discs 8 via their respective adjustment slots 13. A circulating air pump 12 is fixedly installed inside the mounting base 3. A cylinder 11 is also fixedly installed inside the mounting base 3. A rack 10 is fixedly connected to the output end of the piston rod of the cylinder 11. The outlet of the circulating air pump 12 is connected to the inlet of the cylinder 11 via a high-pressure air pipe. The outlet of the cylinder 11 is connected to the inlet of the circulating air pump 12 via a purification pipe. A mounting ring 14 is rotatably installed inside the fixed base 4. A second toothed ring 15 is fitted onto the mounting ring 14. The fixed base 4 contains multiple... The mounting ring 14 is surrounded by a series of ring-shaped limiting plates 16, each rotatably connected to the mounting base 4 via mounting shafts 17. Gears 18 are fitted onto each mounting shaft 17, and these gears mesh with the second gear ring 15. When the charging gun needs to be fixed, the circulating air pump 12 starts, generating air pressure to extend the piston rod of the cylinder 11, pushing the rack 10, which is fixed thereto, to move linearly. The rack 10 meshes with the first gear ring 9 on the adjusting disc 8, causing the adjusting disc 8 to rotate within the mounting base 3. The adjusting disc 8 has three sets of annular inclined or curved adjusting grooves 13. The three sets of adjusting rods 7 are slidably connected to each other. The rotational motion of the adjusting plate 8 is converted into synchronous radial linear motion of the three sets of adjusting rods 7 and their fixed adjusting frames 6 in their respective guide rails 5 through the adjusting groove 13. This enables the three sets of adjusting frames 6 to adaptively clamp or loosen the tails of charging guns of different diameters inserted into them. At the same time, the motor in the fixed base 4 drives a set of mounting shafts 17 to rotate. The second toothed ring 15 meshes with the gears 18 on the multiple sets of mounting shafts 17, so that the multiple sets of mounting shafts 17 rotate synchronously. This, in turn, drives the limiting plates 16 fixed to the mounting shafts 17 to synchronously close or open, so as to achieve a stable constraint on charging cables of different thicknesses.

[0023] like Figure 4 and Figure 5As shown, two sets of cross-distributed brackets 19 are provided between the sleeve 2 and the base 1. The upper ends of the two sets of brackets 19 are rotatably connected to the sleeve 2 via a rotating shaft. A slider 20 is rotatably installed at the lower end of the bracket 19. A sliding rod 21 is fixedly installed inside the base 1. The slider 20 is slidably connected to the base 1. The slider 20 and the sliding rod 21 are slidably sleeved. Two sets of symmetrically distributed first springs 22 are sleeved on the sliding rod 21. The two ends of the first springs 22 are fixedly connected to the slider 20 and the base 1, respectively. A damper 23 is fixedly installed between the slider 20 and the base 1. A second spring 24 is sleeved on the damper 23. When the charging gun or cable is subjected to external vibration, impact or accidental pulling, the force is transmitted to the sleeve 2. After the sleeve 2 is subjected to force, it will drive the two sets of cross brackets 19 rotatably connected to it to move. The lower end of the bracket 19 slides on the slide rod 21 of the base 1 via the slider 20. Two sets of first springs 22 are sleeved on the slide rod 21. The first springs 22 are pre-compressed and further compressed or stretched when the slider 20 moves, absorbing and storing impact energy. At the same time, the damper 23 connected between the slider 20 and the base 1 generates a damping force opposite to the movement speed of the slider 20, effectively dissipating vibration energy and suppressing the reciprocating oscillations generated when the first springs 22 release energy. The second spring 24 sleeved on the damper 23 can provide auxiliary elastic support and restoring force. The synergistic effect of the first springs 22, the second springs 24 and the damper 23 constitutes a highly efficient multi-stage buffer system, which quickly attenuates vibration, prevents impact energy from being directly transmitted to the base 1 or causing the charging gun to loosen or shift, and ensures stability in the fixed state.

[0024] This utility model provides a charging gun tail fixing structure, the specific working principle of which is as follows: When it is necessary to fix the charging gun, the circulating air pump 12 starts to generate air pressure, drives the piston rod of the cylinder 11 to extend, pushes the rack 10 fixed thereto to move linearly, the rack 10 meshes with the first toothed ring 9 on the adjusting plate 8, and drives the adjusting plate 8 to rotate in the mounting base 3. The adjusting plate 8 has three sets of annular inclined or curved adjusting grooves 13, which are slidably connected to three sets of adjusting rods 7 respectively. The rotational motion of the adjusting plate 8 is converted into synchronous radial linear motion of the three sets of adjusting rods 7 and their fixed adjusting frames 6 in their respective guide rails 5 through the adjusting grooves 13. The movement allows for adaptive clamping or loosening of the three sets of adjustment brackets 6, which are inserted into the tails of charging guns of different diameters. Simultaneously, the motor inside the fixed base 4 drives a set of mounting shafts 17 to rotate, and the second gear ring 15 meshes with the gears 18 on multiple sets of mounting shafts 17, enabling multiple sets of mounting shafts 17 to rotate synchronously. This, in turn, drives the limiting plates 16 fixed to the mounting shafts 17 to move synchronously, achieving a stable constraint on charging cables of different thicknesses. When the charging gun or cable is subjected to external vibration, impact, or accidental pulling, the force is transmitted to the sleeve 2. After the sleeve 2 is subjected to force, it will drive the two sets of cross brackets 19 connected to it to move. The lower end of the bracket 19 slides on the slide rod 21 of the base 1 via the slider 20. Two sets of first springs 22 are sleeved on the slide rod 21. The first springs 22 are pre-compressed and further compressed or stretched when the slider 20 moves, absorbing and storing impact energy. At the same time, the damper 23 connected between the slider 20 and the base 1 generates a damping force opposite to the movement speed of the slider 20, effectively dissipating vibration energy and suppressing the reciprocating oscillations generated when the first springs 22 release energy. The second spring 24 sleeved on the damper 23 can provide auxiliary elastic support and restoring force. The synergistic effect of the first springs 22, the second springs 24 and the damper 23 constitutes a highly efficient multi-stage buffer system, which quickly attenuates vibration, prevents impact energy from being directly transmitted to the base 1 or causing the charging gun to loosen or shift, and ensures stability in the fixed state.
