Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically to a mobile charging pile. Background Technology

[0002] In the field of electric vehicle charging, mobile shared charging piles have emerged to solve the problems of gasoline vehicles occupying charging spaces and insufficient power supply capacity in parking lots, especially in underground parking lot applications.

[0003] In existing technologies, most electric vehicle charging stations are installed in fixed locations to charge vehicles. However, fixed-location charging stations limit their applicability and cannot flexibly adapt to various parking layouts and changes in charging locations, causing numerous inconveniences for users. Therefore, current designers use motor-driven methods to move the charging stations to the required locations. However, while motor-driven charging stations solve the problem of location flexibility, they also bring higher costs and more complex maintenance requirements. Motor-driven systems not only increase the initial investment cost of the equipment, but the long-term maintenance workload is also considerable, resulting in a significant burden on users. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mobile charging pile that can be manually pulled to move the charging body and has a lower cost.

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] A mobile charging station, comprising:

[0007] track;

[0008] The first slider can move freely on the track;

[0009] The second slider can move freely on the track;

[0010] The charging body is connected to the first sliding member;

The plurality of second connecting members are connected to a plurality of positions on the cable, with adjacent positions distributed on the cable and spaced apart by a distance.

[0016] In one embodiment, the cable is a straight cable or a spiral cable.

[0017] In one embodiment, the track is provided with multiple limiting structures, each corresponding to a different target position. The multiple limiting structures are used to limit the first slider when it slides on the track, so that the charging body can stay at different target positions.

[0018] In one embodiment, the limiting structure includes a slot or a protrusion.

[0019] In one embodiment, the bottom end of the second slider is located below the horizontal line at the top of the charging body.

[0020] In one embodiment, the charging body includes a housing, a charging motherboard housed within the housing, and a charging gun portion electrically connected to the charging motherboard.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Please refer to Figure 1-4 As shown, this embodiment provides a mobile charging pile, which includes: a track 20, a first sliding member 30, a second sliding member 31, a charging body 40, and a cable 60; wherein, both the first sliding member 30 and the second sliding member 31 can move freely on the track 20, the charging body 40 is connected to the first sliding member 30, and in this embodiment, the charging body 40 is installed on the first sliding member 30, the cable 60 is electrically connected to the charging body 40 and is suspended from the track by the second sliding member 31, and one end of the cable 60 is connected to a power source in the parking lot to provide current, thereby realizing the power supply to the charging pile; wherein, the charging body 40 can slide along the axial direction of the track 20 through the first sliding member 30 and move to the target position, that is, above the charging position of the electric vehicle, thereby realizing the charging of the electric vehicle; moreover, since the cable is connected to the charging body, when the charging body slides, the cable and the second sliding member also slide, and the cable is contracted or stretched.

[0042] Please refer to Figure 2-6 and Figure 9As shown, the cable 60 is supported by the second sliding member to be suspended below the track. The second sliding member 31 includes multiple first connecting members 70 installed on the track 20 and able to slide freely on the track 20, and also includes multiple second connecting members 71. Each first connecting member 70 is provided with a rotatably connected second connecting member 71. In this embodiment, all the first connecting members 70 are located on one side of the first sliding member 30. Any two adjacent first connecting members 70 are spaced apart, and each first connecting member 70 has a rotatable second connecting member 71 at its lower end. The cable 60 passes through all the second connecting members 71 in sequence and is limited and fixed to the inner wall of each second connecting member 71, so that the multiple second connecting members 71 are connected to multiple positions on the cable 60. The adjacent positions are distributed on the cable and spaced apart by a distance.

[0043] Understandably, the cable 60 is connected to the second connector 71 at multiple points spaced apart, allowing the cable 60 to suspend below the track 20. Under external force, the cable can contract or stretch, thus making its length variable. When the charging body 40 is at the starting end (e.g....), Figure 3 As shown), multiple second sliding members 31 approach each other. When the user pulls the charging body 40 to move along the track 20, the cable 60 is driven because the cable is connected to the charging body, and the second connecting member 71 and the first connecting member 70 slide sequentially on the track 20, and the cable is stretched in the length direction.

[0044] Understandably, this design employs a combination structure of a first connector 70 and a second connector 71 to manage the cable 60. The rotatable second connector 71 at the lower end of each first connector 70 allows the cable 60 to smoothly adjust its position as the charging body 40 moves, effectively avoiding damage caused by pulling or tangling. This design not only ensures the safety and durability of the cable 60, but also makes the entire system look neater and more orderly, improving the overall aesthetics.

[0045] In addition, such as Figure 3 As shown, by setting the original position of the charging body 40 (the left or right end of the track 20) ​​and the relative position of the first connector 70, it is ensured that the cable 60 can follow smoothly without obstruction or jamming, no matter which direction the user pulls the charging body 40. This design concept fully considers the actual needs of user experience, making the charging process smoother and more natural.

[0046] Understandably, in this embodiment, the charging unit is moved by the free movement of the first slider on the track. Users can easily move the charging unit to any desired target location for charging, which solves the high cost and maintenance problems caused by relying on motor drive, greatly reduces the moving cost and complexity of the charging pile, and enhances the flexibility and convenience of using the charging pile. It provides users with an economical, practical and easy-to-operate solution, enabling the equipment to adapt to different layouts and application scenarios.

[0047] In this embodiment, the first and second sliding members are roller structures. The structure is simple and the cost is low.

[0048] Please refer to Figure 2-4 As shown, in the first embodiment, the cable is configured as a straight cable 610, and the straight cable 610 is connected to multiple second connectors 71 at multiple points spaced apart. When the charging body is in the starting position, as shown... Figure 3 As shown, the straight cable 610 is compressed along its length, and the straight cable is tightly packed together in a coiled structure. When the charging unit moves, as... Figure 2 As shown, the straight cables in a concentric loop structure are elongated. The advantage of this arrangement is that it prevents the straight cables 610 between the two second connectors 71 from drooping during compression, improving the overall aesthetics of the straight cables 610 on the track 20, and also preventing the drooping of the straight cables 610 from affecting the height of the parking space 100, resulting in higher space utilization.

[0049] like Figure 5 As shown, optionally, in the second embodiment, the cable is configured as a spiral cable 611, and the spiral cable 611 is connected to multiple second connectors 71 at multiple positions spaced apart. The spiral cable 611 with this structure has a larger shrinkage space, and its length can be longer when stretched, making greater use of space and more conducive to saving space.

[0050] Preferably, in some embodiments, the track 20 is set as a straight track and a single track. The slider 30 is set on the single track and slides along the axial direction of the track 20, thereby driving the charging body 40 to move. In the track 20, the charging body 40 is moved to different charging positions on the single track for charging.

[0051] Preferably, in other embodiments, the track 20 is configured as a straight track and a double track. The two sides of the slider 30 are respectively installed in the two tracks of the straight double track and can slide along the axial direction of the straight double track, thereby driving the charging body 40 to slide between the double tracks along the axial direction of the straight double track. In the straight double track, the charging body 40 is moved to different charging positions on the straight double track for charging.

[0052] Preferably, in other embodiments, the track 20 is a curved track. In this embodiment, an S-shaped curved track is selected and it is set as a double track. The two sides of the slider 30 are respectively installed on the curved double track and can slide along the axial direction of the curved double track. The curved double track is used in vehicle parking spaces 100 where the charging positions are not on the same horizontal line. In the curved double track, the charging body 40 is moved to different charging positions on the curved double track for charging.

[0053] In other embodiments, track 20 may also be configured as a curved monorail track.

[0054] In the four different embodiments described above, the number of charging bodies 40 set on the track 20 is one. In other embodiments, it can be set to multiple. On the track 20 with multiple charging bodies 40, a branch rail corresponding to each parking space 100 is set on the track 20 so that the multiple charging bodies 40 do not interfere with each other when moving on the track 20.

[0055] like Figure 4 As shown, preferably, the track is provided with multiple limiting structures, each corresponding to a different target position. The multiple limiting structures are used to limit the sliding of the first sliding member 30 on the track 20, so that the charging body 40 can stay at different target positions.

[0056] Preferably, the limiting structure includes a slot or a protrusion.

[0057] Specifically, the limiting structure can be set as a limiting groove. In this example, the limiting structure is set as a first limiting groove 201a. Multiple first limiting grooves 201a are provided on the track 20. The first sliding member 30 can move along the track 20 and be engaged or disengaged from the first limiting groove 201a. Multiple first limiting grooves 201a are provided on the track 20 and are spaced apart from each other. It can be understood that the position of the first limiting groove 201a in this embodiment corresponds to the target position. That is, after the first sliding member 30 is engaged in the first limiting groove 201a, the charging body 40 suspended by the first sliding member 30 is located at the target position, so that positioning can be performed. The advantage of this structure is that when the charging body 40 stops at the target position that needs to be charged, the first sliding member 30 can be limited, preventing the first sliding member 30 from sliding freely on the track 20, which would cause the charging body 40 to deviate from the target charging position.

[0058] Optionally, although Figure 4 Only one first limiting groove 201a is shown in the diagram, but multiple first limiting grooves 201a can be provided on the track 20. When charging the vehicle using the charging body 40, by pulling the charging body 40, the first sliding member 30 can move and be locked into different first limiting grooves 201a, so that the first sliding member 30 is locked and disengaged in different first limiting grooves 201a. When the user pulls the charging body to the target position corresponding to the charging, the user stops pulling the charging body 40. At this time, the first sliding member 30 is locked. The user can use the charging body 40 to charge the vehicle with confidence without worrying about the charging body 40 deviating during the charging process.

[0059] like Figure 4 As shown, preferably, the bottom end of the second sliding member 31, i.e., the bottom end of the second connecting member 71, is located below the horizontal line of the top end of the charging body 40, that is, the second connecting member 71 is lower than the side of the charging body 40 near the track 20 on the track 20; as Figure 4 The length L1 from the bottom end of the second connector 71 to the top surface of the track 20, and the length L2 from the bottom surface of the charging body 40 to the top surface of the track 20 are shown. ， L1 is greater than L2. This structure is designed to prevent the cable of the charging body 40 from getting caught in the sliding member 30 and causing damage during movement.

[0060] like Figure 6As shown, in some preferred embodiments, the charging body 40 includes a housing 411, a charging motherboard housed within the housing 411, and a charging gun portion 413 electrically connected to the charging motherboard. The mobile charging station also includes a telescopic mechanism 80 and a charging gun 424. The telescopic mechanism 80 is mounted on the charging body 40 and has the charging gun portion 413 on it. The charging gun 424 is detachably plugged into the charging gun portion 413. One end of the charging gun 424 is connected to a cable, and the other end is detachably plugged into the charging gun portion 413. The telescopic mechanism 80 can drive the charging gun portion 413 to telescopically move and move closer to or away from the housing 411 under the action of external force. It can be understood that the telescopic mechanism 80 is used to drive the charging gun portion 413 to move, so that the charging gun 424 on the charging gun portion 413 moves up and down with the charging gun portion 413, thereby moving to a suitable position for picking up or inserting, for use or return of the charging gun 424. In this embodiment, the charging body 40 does not have a cable reel, and the charging gun is equipped with a charging cable 420 electrically connected to the charging motherboard; the charging cable 420 is spiral-shaped. The spiral shape of the charging cable allows for greater contraction and extension space, which is beneficial for convenient long-distance charging when the cable is extended, while also preventing the cable from becoming too long when contracted. In this embodiment, the charging body does not contain a cable reel or related electrical components for operating the cable reel, thus saving significant costs.

[0061] like Figure 7 As shown, in preferred embodiments, the charging body 40 includes a housing 411, a charging main board housed within the housing 411, and a charging gun portion 413 electrically connected to the charging main board. However, the charging body 40 does not contain a cable reel or a charging gun. The charging station also includes a telescopic mechanism 80, which is mounted on the charging body 40, and the charging gun portion 413 is mounted on the telescopic mechanism 80. The telescopic mechanism 80 can extend and retract downwards on the charging body 40 to move the charging gun portion 413. The telescopic mechanism 80 is used to move the charging gun portion 413. It is understood that this embodiment is applied to the case where the user brings their own charging gun. The user inserts their own charging gun into the charging gun portion 413 to connect the charging gun to power. This mobile charging station structure has no charging gun and no cable reel, making it simpler and less expensive.

[0062] Preferably, the maximum height of the telescopic mechanism 80 from the ground is not less than 150 cm. It can be understood that in this embodiment, by setting the distance between the telescopic mechanism 80 and the ground, the telescopic height of the telescopic mechanism 80 is avoided from being too high from the ground, which would result in the height of the charging gun part 413 on the telescopic mechanism 80 being too high, thus preventing the charging gun 424 inserted therefrom from charging the vehicle waiting to be charged in the parking space.

[0063] like Figure 8As shown, in some preferred embodiments, the charging body 40 includes a housing 421, a charging gun 424, a charging motherboard 422 housed in the housing 421, and a cable reel 423. The cable reel 423 is provided with a charging cable 425 that is electrically connected to the charging motherboard 422 and the charging gun 424. Since the cable is electrically connected to the charging motherboard, the charging cable 425 is electrically connected to the charging motherboard 422. The charging gun 424 is connected to the charging cable 425, and the end of the charging cable 425 is connected into the inside of the cable reel 423 and electrically connected to the cable.

[0064] Please refer to Figure 4-5 As shown, the housing 421 is further provided with a through hole 421a that can accommodate the charging gun 424 to extend or retract. It can be understood that in the charging body 40 structure with a winding reel 423, the charging gun 424 can retract the charging cable 425 by rotating the winding reel 423, so that the charging gun 424 can be retracted from the through hole 421a and housed in the housing 421, or it can be lowered out from the through hole 421a of the housing 421 by rotating the winding reel 423.

[0065] like Figure 8 As shown, preferably, in the design scheme of the above embodiment, the charging body further includes a driving component 913 for controlling the cable reel 423 to release or retract the cable. In this embodiment, the driving component 913 is configured as a drive motor. The driving component 913 is installed in the housing 421 of the charging body 40. The charging gun 424 is provided with a button 912. The button 912 is used to control the length of the charging cable 425. By pressing the button 912, the operation of the driving component 913 is controlled, so that the driving component 913 rotates to drive the charging cable 425 to be released or pulled back.

[0066] Preferably, the maximum height of the charging gun above the ground is not less than 150 cm.

[0067] In the two solutions mentioned above, designers can switch between two different charging gun 424 usage modes according to specific usage scenarios to provide users with a better experience.

[0068] Please refer to Figure 1-4 As shown, preferably, the mobile charging pile also includes a flexible traction mechanism 50 installed on the charging body 40. The height of the flexible traction mechanism 50 from the ground is not less than 150 cm. It can be understood that in this embodiment, the flexible traction mechanism 50 is set as a flexible connecting belt for traction of the charging body 40. By pulling the flexible traction mechanism 50, the charging body 40 is moved to the target position. In addition, this embodiment sets the height range of the flexible traction mechanism 50 from the ground to avoid the flexible traction mechanism 50 being too high, making it difficult for the user to pull.

[0069] Optionally, the telescopic mechanism in the above embodiments is made of metal to improve the structural robustness of the telescopic mechanism and make its movement more stable.

[0070] like Figure 4 As shown, preferably, the straight-line distance L3 between the side of the track 20 away from the charging body 40 and the side of the charging body 40 away from the track 20 is between 15 and 30 cm. By limiting the distance between the highest surface of the track 20 and the lowest surface of the charging body 40, the overall height of the charging pile is limited. In an underground parking lot, the height of the parking space 100 determines whether a vehicle can be parked there. By limiting the height of the charging pile above the parking space 100, when the underground parking garage assembles the charging pile of this structure, the charging pile is located directly above the parking space 100 on the top wall. This allows the vehicle to be quickly charged by pulling the charging body 40 when it enters the parking space 100, avoiding the space of the parking space 100 being affected by the charging pile being designed too high or too low.

[0071] Please refer to Figure 1-2 As shown, preferably, the mobile charging pile also includes a first baffle 81 arranged along the axial direction of the track 20 and a second baffle 82 disposed at the end of the track 20. There are two of each of the first baffle 81 and the second baffle 82, which are respectively disposed on opposite sides, thereby providing all-round shielding of the track 20, cables and charging body, making the overall appearance of the charging pile more aesthetically pleasing. The second baffle 82 is used to shield the first sliding member 30 and the second sliding member 31 to prevent them from sliding off the track.

[0072] Preferably, the width L4 of the first baffle and / or the second baffle is between 15 and 30 cm; optionally, in this embodiment, the width L4 of the first baffle 81 and the second baffle 82 is the same, and the width L4 range limits the first baffle 81 and the second baffle 82, so as to avoid the first baffle 81 and the second baffle 82 being too long and causing the space of the vehicle parking position to be compressed, and also to avoid the width L4 being too short and causing the structure in the track to be not completely blocked.

[0073] In summary, this utility model provides a mobile charging station that uses the free movement of a sliding component on a track to move the charging unit. Users can easily move the charging unit to any desired location for charging, solving the high cost and maintenance problems associated with motor-driven systems. This significantly reduces the cost and complexity of moving the charging station and enhances its flexibility and convenience. It provides users with an economical, practical, and easy-to-operate solution, enabling the device to adapt to different layouts and application scenarios.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
