Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically a self-locking device for new energy charging piles. Background Technology

[0002] Charging stations function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging station is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging stations generally provide two charging methods: regular charging and fast charging. Users can use a specific charging card by swiping it on the human-machine interface provided by the charging station.

[0003] Currently, charging cables at charging stations are typically exposed. When charging a vehicle, the charging gun is inserted into the vehicle's surface, and the long cable can easily trip over passersby, posing a safety hazard. When not charging, the charging gun is usually placed in a fixed compartment and secured to the charging station with clips. However, the locking effect is not very strong. When the charging cable is pulled by external forces, the clips can easily loosen or even be damaged, causing the charging gun to fall off, resulting in poor usability. Summary of the Invention

[0004] The purpose of this invention is to provide a self-locking device for new energy charging piles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A self-locking device for a new energy charging pile includes a charging pile and a charging gun. One end of the charging gun is connected to a charging cable, and the end of the charging cable away from the charging gun is connected to the charging pile. A storage compartment is provided on the side wall of the charging pile, and a locking cylinder is provided on the outside of the charging pile. A positioning component is provided on the surface of the charging pile, and the positioning component is connected to the storage compartment and the locking cylinder. The positioning component is used to adjust the position angle of the storage compartment and the locking cylinder, thereby synchronously adjusting the position angle of the charging gun. A locking mechanism is provided on the surface of the charging gun. The locking mechanism includes a self-locking component and a protective component. The self-locking component is disposed inside the locking cylinder and is used to fix the charging gun inside the locking cylinder. The protective component is disposed on the surface of the charging cable and is used to fix the position of the charging cable on the outside of the vehicle.

[0007] As a further aspect of the present invention: the positioning component includes a storage groove provided on the side wall of the charging pile, a semi-circular structure inside the storage groove, a rotating shaft provided on the surface of the placement cylinder, the placement cylinder being rotatably installed in the storage groove via the rotating shaft, a fixing block being fixedly installed on the surface of the locking cylinder, and an annular guide rod being fixedly installed on the side wall of the charging pile, the fixing block being slidably installed on the surface of the guide rod.

[0008] As a further aspect of the present invention: the self-locking assembly includes a plurality of vertical guide grooves arranged in an annular pattern and evenly spaced on the inner sidewall of the locking cylinder; a horizontal guide groove is provided on the inner sidewall of the locking cylinder; the horizontal guide groove is connected to the inner end of the vertical guide groove; a locking groove is provided on the inner sidewall of the locking cylinder; the locking groove is connected to the end of the horizontal guide groove away from the vertical guide groove; a locking block is fixedly installed on the surface of the charging gun; an annular baffle is fixedly installed on the surface of the charging gun; and a plurality of compression springs are fixedly installed on the surface of the locking cylinder.

[0009] As a further aspect of the present invention: the protective component includes a fixing member fixedly mounted on the surface of the charging cable, a suction cup is provided at the end of the fixing member away from the charging cable, a vent hole is opened on the surface of the suction cup, and a sealing plug is detachably installed in the vent hole.

[0010] As a further aspect of the present invention: two positioning springs are fixedly installed inside the storage slot, the two positioning springs are respectively located on both sides of the placement cylinder, and the extension and retraction ends of the positioning springs are connected to the side wall of the placement cylinder.

[0011] As a further aspect of the present invention: a traction rope is fixedly installed on the surface of the fixing member, and the end of the traction rope away from the fixing member is connected to the sealing plug.

[0012] As a further embodiment of the present invention: the card block is made of magnetic material, and a magnetic block is fixedly installed in the card slot.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the positioning component and the self-locking component to cooperate with each other, the position and angle of the charging gun can be easily adjusted. When the charging cable is pulled by external force, it can effectively prevent the charging gun and the charging cable from being severely bent at the connection position. It can also easily lock the position of the charging gun, effectively improving the installation and use effect of the charging gun. It solves the problem that the current charging pile locking effect is generally poor, the buckle and the charging gun are easy to loosen or even be damaged, causing the charging gun to fall off and the use effect is poor.

[0014] By setting up protective components in conjunction with the charging cable, a portion of the charging cable can be controlled to provide buffering during the charging process, thereby providing tensile protection for the charging gun and effectively preventing the charging gun from becoming loose at the vehicle's charging port, thus improving the charging effect.

Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0025] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4The diagram shown is a structural diagram of a self-locking device for a new energy charging pile according to an embodiment of the present invention. It includes a charging pile 1 and a charging gun 2. One end of the charging gun 2 is connected to a charging cable 21, and the end of the charging cable 21 away from the charging gun 2 is connected to the charging pile 1. A storage compartment 3 is provided on the side wall of the charging pile 1, and a locking cylinder 31 is provided on the outer side of the charging pile 1. A positioning component 4 is provided on the surface of the charging pile 1, and the positioning component 4 is connected to the storage compartment 3 and the locking cylinder 31. The positioning component 4 is used to adjust the position angle of the storage compartment 3 and the locking cylinder 31, thereby synchronously adjusting the position angle of the charging gun 2. A locking mechanism 5 is provided on the surface of the charging gun 2. The locking mechanism 5 includes a self-locking component 51 and a protective component 52. The self-locking component 51 is disposed inside the locking cylinder 31 and is used to fix the charging gun 2 inside the locking cylinder 31. The protective component 52 is disposed on the surface of the charging cable 21 and is used to fix the position of the charging cable 21 on the outside of the vehicle.

[0027] Positioning component 4 positions the placement chamber 3 and locking cylinder 31 on the side wall of charging pile 1. When not in use, charging gun 2 passes through locking cylinder 31 and is inserted into placement chamber 3. Self-locking component 51 stably fixes charging gun 2 inside locking cylinder 31, while charging cable 21 is exposed outside charging pile 1. When charging cable 21 is pulled by external force, it applies tension to charging gun 2, and self-locking component 51 continuously fixes charging gun 2 inside locking cylinder 31. During this process, charging gun 2 and placement chamber 3 remain relatively stationary, effectively preventing loosening between them and improving the service life of charging gun 2. When the vehicle needs to be charged, the self-locking component 51 can easily release the restriction of the locking cylinder 31 on the charging gun 2. The user can then easily remove the charging gun 2 from the storage compartment 3 and insert it into the charging port on the vehicle surface. During charging, the charging cable 21 remains exposed on the outside of the vehicle. The protective component 52 positions a portion of the charging cable 21 on the side wall of the vehicle. When the charging cable 21 is pulled by an external force, the protective component 52 can control a portion of the charging cable 21 to form a buffer, preventing the charging cable 2 from being affected by the pulling. The charging gun 2 remains stably inserted into the charging port on the vehicle surface for continuous charging, effectively improving the charging efficiency. After charging is completed, the protective component 52 releases the restriction on the charging cable 21, and the user passes the charging gun 2 through the locking cylinder 31 and inserts it back into the storage compartment 3.

[0028] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, in a preferred embodiment of the present invention, the positioning component 4 includes a storage groove 41 provided on the side wall of the charging pile 1, the storage groove 41 having a semi-circular structure, the surface of the placement cylinder 3 being provided with a rotating shaft 42, the placement cylinder 3 being rotatably installed in the storage groove 41 via the rotating shaft 42, the surface of the locking cylinder 31 being fixedly installed with a fixing block 43, the side wall of the charging pile 1 being fixedly installed with an annular guide rod 44, and the fixing block 43 being slidably installed on the surface of the guide rod 44.

[0029] The rotating shaft 42 positions the storage compartment 3 within the storage slot 41, while the guide rod 44 positions the fixing block 43 and the locking cylinder 31. The charging gun 2 passes through the locking cylinder 31 and is inserted into the storage compartment 3. When the charging cable 21 is pulled by an external force and a tension is applied to the charging gun 2, the storage compartment 3 rotates within the storage slot 41. The locking cylinder 31 and the fixing block 43 rotate along the length of the guide rod 44, thereby synchronously adjusting the position and angle of the charging gun 2. This effectively prevents the charging gun 2 from locking up and the charging cable 21 from severely bending at the connection point, effectively improving the service life of the charging gun 2 and the charging cable 21.

[0030] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the self-locking assembly 51 includes a plurality of vertical guide grooves 511 arranged in an annular pattern and evenly spaced on the inner wall of the locking cylinder 31, a horizontal guide groove 512 provided on the inner wall of the locking cylinder 31, the horizontal guide groove 512 being connected to the inner end of the vertical guide groove 511, a locking groove 513 provided on the inner wall of the locking cylinder 31, the locking groove 513 being connected to the end of the horizontal guide groove 512 away from the vertical guide groove 511, a locking block 514 fixedly installed on the surface of the charging gun 2, an annular baffle 515 fixedly installed on the surface of the charging gun 2, and a plurality of compression springs 516 fixedly installed on the surface of the locking cylinder 31.

[0031] During the process of passing the charging gun 2 through the locking cylinder 31 and inserting it into the placement chamber 3, the locking block 514 on the surface of the charging gun 2 slides in the vertical guide groove 511. When the locking block 514 moves to the deepest part of the vertical guide groove 511, the compression spring 516 applies a pushing force to the baffle 515 on the surface of the locking cylinder 31. The user rotates the charging gun 2, at which time the locking block 514 moves in the horizontal guide groove 512. When the locking block 514 moves to the end of the horizontal guide groove 512 away from the vertical guide groove 511, the user releases the charging gun 2, and the compression spring 516 pushes the charging gun 2 and the baffle 515 to move in the opposite direction. At this time, the locking block 514 is stably inserted into the slot 513. The multiple locking blocks 514 and the slot 513 cooperate with each other to conveniently fix the charging gun 2 in the locking cylinder 31. When charging is required, the user applies a pushing force to the charging gun 2, thereby moving the charging gun 2. At this time, the locking block 514 moves in the opposite direction into the horizontal guide groove 512. Rotating the charging gun 2 causes the locking block 514 to move in the direction of the vertical guide groove 511 within the horizontal guide groove 512. When the locking block 514 is aligned with the vertical guide groove 511, the user can easily pull the charging gun 2 out of the locking cylinder 31.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, in a preferred embodiment of the present invention, the protective component 52 includes a fixing member 521 fixedly mounted on the surface of the charging cable 21. A suction cup 522 is provided at one end of the fixing member 521 away from the charging cable 21. A vent hole is opened on the surface of the suction cup 522, and a sealing plug 523 is detachably installed in the vent hole.

[0033] When charging the vehicle, the suction cup 522 is pressed against the vehicle surface, ensuring it remains stable. The suction cup 522, in conjunction with the fixing component 521, positions the charging cable 21. When the charging cable 21 is pulled by external force, the suction cup 522 can control a portion of the cable, creating a buffer and preventing it from affecting the charging gun 2. The charging gun 2 remains stably inserted into the charging port on the vehicle surface, continuously charging and effectively improving charging efficiency. After charging is complete, the sealing plug 523 on the surface of the suction cup 522 is removed, opening the vent. The suction cup 522 then detaches from the vehicle side wall, releasing the restriction on the charging cable 21.

[0034] like Figure 3 As shown, in a preferred embodiment of the present invention, two positioning springs 6 are fixedly installed in the storage slot 41. The two positioning springs 6 are located on both sides of the placement cylinder 3, and the extension and retraction ends of the positioning springs 6 are connected to the side wall of the placement cylinder 3.

[0035] The positioning spring 6 further positions the placement chamber 3 within the storage slot 41, thereby further improving the stability of the placement chamber 3 and the charging gun 2.

[0036] like Figure 8 As shown, in a preferred embodiment of the present invention, a traction rope 7 is fixedly installed on the surface of the fixing member 521, and the end of the traction rope 7 away from the fixing member 521 is connected to the sealing plug 523.

[0037] In a preferred embodiment of the present invention, the card block 514 is made of magnetic material, and a magnetic block is fixedly installed in the card slot 513.

[0038] The working principle of this invention is as follows: When the charging gun 2 is not in use, it passes through the locking cylinder 31 and is inserted into the placement chamber 3. During the process of passing the charging gun 2 through the locking cylinder 31 and inserting it into the placement chamber 3, the locking block 514 on the surface of the charging gun 2 slides in the vertical guide groove 511. When the locking block 514 moves to the deepest part of the vertical guide groove 511, the compression spring 516 applies a pushing force to the baffle 515 on the surface of the locking cylinder 31. When the user rotates the charging gun 2, the locking block 514 moves in the horizontal guide groove 512. When the locking block 514 moves to the end of the horizontal guide groove 512 away from the vertical guide groove 511, the user releases the charging gun 2. The compression spring 516 pushes the charging gun 2 and the baffle 515 to move in the opposite direction. At this time, the locking block 514 is stably inserted into the slot 513. The multiple locking blocks 514 and the slot 513 cooperate with each other to conveniently fix the charging gun 2 in the locking cylinder 31.

[0039] When charging is required, the user applies a pushing force to the charging gun 2, causing it to move. At this time, the locking block 514 moves in the opposite direction into the horizontal guide groove 512. Rotating the charging gun 2 causes the locking block 514 to move towards the vertical guide groove 511 within the horizontal guide groove 512. Once the locking block 514 is aligned with the vertical guide groove 511, the user can easily pull the charging gun 2 out of the locking cylinder 31. The charging gun 2 is then inserted into the charging port on the vehicle surface. During charging, the charging cable 21 remains exposed on the outside of the vehicle. The suction cup 522 is pressed against the vehicle surface, ensuring its stable position. The suction cup 522, in conjunction with the fixing member 521, positions the charging cable 21. When the charging cable 21 is pulled by an external force, the suction cup 522 can control a portion of the cable to form a buffer, preventing damage to the charging gun 2. The charging gun 2 remains stably inserted into the charging port on the vehicle surface, continuously charging and effectively improving the charging efficiency. After charging is complete, remove the sealing plug 523 from the surface of the suction cup 522. At this time, the vent is open, and the suction cup 522 detaches from the side wall of the vehicle, thereby releasing the restriction on the charging cable 21.

[0040] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
