Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging pile technology, and in particular to a mobile charging pile for new energy vehicles. Background Technology

[0002] Charging piles for new energy vehicles are specialized devices that provide electrical energy replenishment for these vehicles. Their core function is to transmit alternating current (AC) from the power grid (or convert it to direct current through a built-in rectifier module) to the vehicle's power battery through a standardized charging interface, thus realizing battery energy storage. They are equivalent to the "gas station pump" for traditional gasoline vehicles and are a key infrastructure supporting the widespread adoption of new energy vehicles. Based on installation scenarios, they can be categorized into public charging piles, private charging piles, and dedicated charging piles; based on charging power, they can be categorized into slow charging piles (AC piles) and fast charging piles (DC piles).

[0003] Traditional charging piles are mostly fixed installations (such as parking lot pillars or ground pre-embedded ones), but with the growth of the number of new energy vehicles and the diversification of usage scenarios, the demand for mobile charging piles has gradually become prominent. The core reason is to solve the limitations of fixed charging piles and improve the flexibility and coverage of charging services.

[0004] A search revealed a patent document with publication number CN221340260U that discloses a portable charging pile for new energy vehicles. The charging pile includes a charging pile body, a fixed base plate installed on the bottom outer wall of the charging pile body, and support plates installed on the bottom outer wall of the fixed base plate. A dovetail slide plate is pulled out from inside the dovetail base, and a support spring drives the locking connector to re-engage with the dovetail slide plate. Then, the adjusting bolt is reversed. This charging pile can prevent malicious interruption during charging and prevent malicious damage to the display and buttons on the charging pile body when not in use.

[0005] However, during use, the above-mentioned charging piles still have the following technical problems:

[0006] During the relocation of charging stations, the slope of the road surface is unpredictable. When encountering uphill or downhill sections, the charging station will tilt during the relocation process. This will not only cause the electrical components inside the charging station to shift, making the charging station unable to operate normally, but also pose a risk of the charging station tipping over and falling, affecting the service life of the charging station. Utility Model Content

[0007] The purpose of this invention is to solve the problem in the prior art where the charging pile body is tilted during movement, causing the charging pile to malfunction. The invention proposes a movable charging pile for new energy vehicles that avoids tilting when moving on sloping roads and prevents internal electrical components from failing due to displacement.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A portable charging station for new energy vehicles, comprising:

[0010] The charging pile body has a protective mechanism on its side wall to protect the buttons and display screen on the charging pile body when it is moved. The lower end of the charging pile body has a support mechanism for moving the charging pile body.

[0011] The protective mechanism includes limiting grooves on both sides of the charging pile body. Two symmetrically distributed U-shaped protective plates are slidably connected between the two limiting grooves in the vertical direction. A bidirectional threaded rod is rotatably connected in each limiting groove. The two sides of the bidirectional threaded rod are provided with threads in opposite directions. The threads on both sides of the bidirectional threaded rod are threadedly connected to the two U-shaped protective plates respectively. A drive motor for driving the bidirectional threaded rod is fixedly connected inside the charging pile body.

[0012] The support mechanism includes a support plate fixedly connected to the lower end of the charging pile body. The lower end of the support plate is provided with a fixed wheel assembly and a movable wheel assembly. The fixed wheel assembly includes two fixed plates fixedly connected to the lower end of the support plate and a fixed roller rotatably connected between the two fixed plates. The movable wheel assembly includes two telescopic plates fixedly connected to the lower end of the support plate and a movable roller rotatably connected between the telescopic ends of the two telescopic plates.

[0013] Preferably, it further includes: a slope adjustment mechanism for adjusting the height of the moving wheel assembly according to the slope of the road surface, so that the charging pile body can be transported in a vertical state. The slope adjustment mechanism includes a movable plate hinged to one side wall of the support plate. A support block is fixedly connected to the lower end of the movable plate. A rotating rod is rotatably connected to the support block. Support rods are fixedly connected to both ends of the rotating rod. A detection roller is rotatably connected between the two support rods. A detection groove is opened inside the movable plate. A counterweight piston plate is slidably connected in the detection groove. A return spring is provided between the counterweight piston plate and the inner wall of the detection groove. A three-way pipe is fixedly connected to one side outer wall of the movable plate. One end of the three-way pipe is connected to the inside of the detection groove, and the other two ends are respectively connected to the inside of two telescopic plates.

[0014] Preferably, there are two drive motors, which are used to drive two bidirectional threaded rods respectively, and the two drive motors are controlled by a PLC controller to always move synchronously, and the two bidirectional threaded rods always move in the same way.

[0015] Preferably, the telescopic plate includes a fixed outer sleeve fixedly connected to the lower end of the support plate, and a movable inner rod that is sealed and slidably connected to the inner wall of the fixed outer sleeve.

[0016] Preferably, the other two ends of the three-way pipe are respectively connected to the interior of the two fixed outer sleeves, and a liquid storage space is formed between the interior of the two fixed outer sleeves, the three-way pipe and the interior of the detection tank, and the liquid storage space is filled with hydraulic oil.

[0017] Preferably, a push handle is fixedly connected to the end of the support plate away from the movable plate.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. By setting up a protective mechanism, this utility model can close the button and display screen area with a protective plate before moving, avoiding direct impact from external objects during the movement; when in use, the protective plate quickly resets without affecting normal operation, greatly reducing the probability of equipment failure due to physical damage and extending the service life of the charging pile.

[0020] 2. This utility model achieves adaptive slope balance through the coordinated design of the slope adjustment mechanism and the support mechanism:

[0021] The support mechanism adopts a combination structure of "fixed wheel set + movable wheel set". The fixed wheel set provides basic support, while the movable wheel set achieves height adjustment through a telescopic plate (fixed outer sleeve + movable inner rod), providing a structural basis for balance adjustment.

[0022] The slope adjustment mechanism senses changes in road slope in real time through the detection rollers. In conjunction with the counterweight piston plate, return spring and hydraulic transmission system (the reservoir is filled with hydraulic oil) in the movable plate, it realizes dynamic adjustment of the height of the moving wheel set: the moving wheel set is raised when going uphill and lowered when going downhill, ensuring that the support plate always remains in a horizontal state.

[0023] It fundamentally avoids the tilting problem of charging piles when moving on sloping roads, prevents internal electrical components from failing due to displacement, and eliminates the safety hazard of equipment tipping over and falling, significantly improving the safety of movement on complex road surfaces.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1 to 3 A portable charging station for new energy vehicles, comprising:

[0034] The charging pile body 1 has a protective mechanism 2 on its side wall to protect the buttons and display screen on the charging pile body 1 when it is moved. The lower end of the charging pile body 1 has a support mechanism 3 for moving the charging pile body 1.

[0035] The protective mechanism 2 includes limiting grooves 21 on both sides of the charging pile body 1. Two symmetrically distributed U-shaped protective plates 22 are slidably connected between the two limiting grooves 21 in the vertical direction. A bidirectional threaded rod 23 is rotatably connected in each limiting groove 21. The two sides of the bidirectional threaded rod 23 are provided with threads in opposite directions. The threads on both sides of the bidirectional threaded rod 23 are threadedly connected to the two U-shaped protective plates 22 respectively. A drive motor for driving the bidirectional threaded rod 23 is fixedly connected inside the charging pile body 1.

[0036] Specifically, there are two drive motors, which are used to drive two bidirectional threaded rods 23 respectively. The two drive motors are controlled by a PLC controller to always move synchronously, so that the two bidirectional threaded rods 23 always move in the same way, thereby enabling the two U-shaped protective plates 22 to move closer to each other or further away from each other.

[0037] Before moving the charging pile, a protective mechanism 2 is used to prevent damage to the buttons and display screen on the charging pile body 1 during the movement. The drive motor inside the charging pile body 1 is started. Since the two drive motors are synchronously controlled by a PLC controller, they can drive the bidirectional threaded rods 23 in the two limit slots 21 to rotate synchronously. Because the two sides of the bidirectional threaded rods 23 have threads with opposite helical directions, and the threads on both sides are threadedly connected to two U-shaped protective plates 22, when the bidirectional threaded rods 23 rotate, the two U-shaped protective plates 22 will move closer to each other in the vertical direction until they completely cover the button and display screen area on the charging pile body 1, thus achieving protection during the movement. When the charging pile reaches the target position and stops moving, the drive motor is reversed by the PLC controller, the bidirectional threaded rods 23 rotate in the opposite direction, and the two U-shaped protective plates 22 move away from each other and reset, exposing the buttons and display screen for normal use.

[0038] The support mechanism 3 includes a support plate 31 fixedly connected to the lower end of the charging pile body 1. The lower end of the support plate 31 is provided with a fixed wheel set 32 ​​and a movable wheel set 33. The fixed wheel set 32 ​​includes two fixed plates 321 fixedly connected to the lower end of the support plate 31 and a fixed roller 322 rotatably connected between the two fixed plates 321. The movable wheel set 33 includes two telescopic plates 331 fixedly connected to the lower end of the support plate 31 and a movable roller 332 rotatably connected between the telescopic ends of the two telescopic plates 331.

[0039] Specifically, the telescopic plate 331 includes a fixed outer sleeve fixedly connected to the lower end of the support plate 31, and a movable inner rod that is sealed and slidably connected to the inner wall of the fixed outer sleeve.

[0040] When moving the charging station, staff can hold the push handle on the end of the support plate 31 away from the movable plate 41 and move the entire station through the support mechanism 3. The fixed wheel set 32 ​​in the support mechanism 3 is the basic support structure. Two fixed plates 321 form a stable limit on the fixed rollers 322, and the fixed rollers 322 provide basic moving support in contact with the ground. The moving wheel set 33 works with the slope adjustment mechanism 4 to achieve height adjustment. Its telescopic plate 331 consists of a fixed outer sleeve and a slidingly connected moving inner rod. The moving rollers 332 are rotatably connected to the end of the moving inner rod and work together with the fixed rollers 322 to enable the charging station to move smoothly on the ground.

[0041] The slope adjustment mechanism 4 is used to adjust the height of the moving wheel set 33 according to the slope of the road surface, so that the charging pile body 1 can be transported in a vertical state. The slope adjustment mechanism 4 includes a movable plate 41 hinged to one side wall of the support plate 31. A support block 42 is fixedly connected to the lower end of the movable plate 41. A rotating rod 43 is rotatably connected to the support block 42. Support rods 44 are fixedly connected to both ends of the rotating rod 43. A detection roller 45 is rotatably connected between the two support rods 44. A detection groove 46 is opened inside the movable plate 41. A counterweight piston plate 47 is slidably connected inside the detection groove 46. A return spring 48 is provided between the counterweight piston plate 47 and the inner wall of the detection groove 46. A three-way pipe 49 is fixedly connected to one side outer wall of the movable plate 41. One end of the three-way pipe 49 is connected to the inside of the detection groove 46, and the other two ends are connected to the inside of the two telescopic plates 331 respectively.

[0042] Specifically, the other two ends of the three-way pipe 49 are respectively connected to the interior of the two fixed outer sleeves, and a liquid storage space is formed between the interior of the two fixed outer sleeves, the three-way pipe 49 and the interior of the detection tank 46, and the liquid storage space is filled with hydraulic oil.

[0043] Specifically, a push handle is fixedly connected to one end of the support plate 31 away from the movable plate 41.

[0044] When the charging pile moves on a sloping road surface, the slope adjustment mechanism 4 can adjust the height of the moving wheel set 33 in real time to ensure that the charging pile body 1 remains vertical. The specific process is as follows: The movable plate 41 is hinged to the side wall of the support plate 31, and its lower end support block 42 is connected to the support rod 44 and the detection roller 45 through the rotating rod 43, which are always in contact with the ground. When there is an uphill or downhill slope on the road surface, the detection roller 45 drives the movable plate 41 to rotate around the hinge point as the road surface slope changes. At this time, the counterweight piston plate 47 in the detection groove 46 inside the movable plate 41 will overcome the elastic force of the return spring 48 and slide in a sealed manner in the detection groove 46 due to gravity and slope changes. Since the detection groove 46, the three-way pipe 49 and the fixed outer sleeve of the telescopic plate 331 form a sealed liquid storage space and are filled with hydraulic oil, the sliding of the counterweight piston plate 47 will squeeze or draw the hydraulic oil, so that the hydraulic oil flows in the liquid storage space through the three-way pipe 49. When on a downhill section, the height of the end where the detection roller 45 is located decreases, the movable plate 41 rotates, causing the counterweight piston plate 47 to compress the hydraulic oil. The hydraulic oil flows into the fixed outer sleeve through the three-way pipe 49, pushing the moving inner rod downward to lower the height of the moving roller 332. When on an uphill section, the height of the end where the detection roller 45 is located increases, the counterweight piston plate 47 resets under the action of the return spring 48, the hydraulic oil flows back from the fixed outer sleeve to the detection groove 46, and the moving inner rod retracts upward to raise the height of the moving roller 332. Through the above hydraulic transmission adjustment, the height of the moving wheel set 33 changes in real time with the slope, and together with the fixed wheel set 32, keeps the support plate 31 in a horizontal state, thereby ensuring that the charging pile body 1 is vertical, avoiding displacement or damage to internal electrical components due to tilting, and preventing the charging pile from tipping over and falling.

[0045] The functional principle of this utility model can be explained through the following operation methods:

[0046] I. Protective Function Principle of Protective Mechanism 2

[0047] The core function of the protective mechanism 2 is to physically isolate and protect the buttons and display screen on the charging pile body 1 during the movement of the charging pile, so as to avoid damage to the equipment due to external forces such as collision and friction.

[0048] Drive control: The charging pile body 1 is equipped with two drive motors, which respectively drive the bidirectional threaded rods 23 in the two limit slots 21. The two drive motors are synchronized through a PLC controller to ensure that the rotation direction and speed of the two bidirectional threaded rods 23 are completely consistent.

[0049] Transmission and protection actions: The two sides of the bidirectional threaded rod 23 are machined with threads in opposite directions, and the threads on both sides are threadedly connected to the two U-shaped protective plates 22 respectively. When the drive motor rotates forward, the bidirectional threaded rod 23 rotates synchronously. Due to the opposite thread direction, the two U-shaped protective plates 22 move closer to each other along the vertical direction of the limiting groove 21 until they completely cover the button and display screen area, forming a closed protective space. When the charging pile moves to the target position, the drive motor reverses, the bidirectional threaded rod 23 rotates in the opposite direction, the two U-shaped protective plates 22 move away from each other and reset, exposing the operating interface for normal use.

[0050] II. Principle of the movable support function of support mechanism 3

[0051] The support mechanism 3 provides a mobile foundation and stable support for the charging pile, and achieves flexible movement through the cooperation of the fixed wheel set 32 ​​and the mobile wheel set 33.

[0052] Function of fixed wheel assembly 32: Fixed wheel assembly 32 consists of two fixed plates 321 and fixed rollers 322. The fixed plates 321 are vertically fixed to the lower end of the support plate 31, providing rigid restraint for the fixed rollers 322. The fixed rollers 322 are rotatably connected between the two fixed plates 321 via a rotating shaft, serving as a basic support point in contact with the ground, bearing part of the equipment's weight and assisting in movement.

[0053] Function of the movable wheel set 33: The movable wheel set 33 consists of two telescopic plates 331 and movable rollers 332. The fixed outer sleeve of the telescopic plate 331 is fixedly connected to the lower end of the support plate 31. The movable inner rod is nested inside the fixed outer sleeve through a sealed sliding structure to achieve length extension and retraction adjustment. The movable rollers 332 are rotatably connected between the telescopic ends of the two movable inner rods, and can adjust their contact position with the ground according to the height change of the telescopic plate 331, thus enabling overall movement in conjunction with the fixed wheel set 32. Workers apply pushing force by gripping the push handle on the support plate 31, driving the fixed rollers 322 and movable rollers 332 to roll, completing the relocation of the charging pile.

[0054] III. The Principle of Balance Adjustment Function of Slope Adjustment Mechanism 4

[0055] The slope adjustment mechanism 4 detects the road slope in real time and adjusts the height of the moving wheel set 33 to ensure that the charging pile body 1 remains vertical when moving on an inclined road, thus preventing internal components from shifting or the equipment from tipping over.

[0056] Slope detection: The movable plate 41 is hinged to one side wall of the support plate 31. Its lower end is connected to the detection roller 45 through the support block 42, the rotating rod 43 and the support rod 44. The detection roller 45 is always in contact with the ground. When there is a slope on the road surface, the detection roller 45 drives the movable plate 41 to rotate around the hinge point as the road surface height changes, so that the movable plate 41 forms an inclination angle with the horizontal plane.

[0057] Hydraulic transmission adjustment: The detection groove 46 inside the movable plate 41, the three-way pipe 49, and the fixed outer sleeve of the telescopic plate 331 form a sealed liquid storage space, which is filled with hydraulic oil. The counterweight piston plate 47 inside the detection groove 46, affected by gravity and slope, overcomes the elastic force of the return spring 48 and slides sealed along the detection groove 46.

[0058] When going downhill, the height of the detection roller 45 decreases, the movable plate 41 tilts, causing the counterweight piston plate 47 to compress the hydraulic oil. The hydraulic oil flows into the fixed outer sleeve through the three-way pipe 49, pushing the moving inner rod to extend downward and reducing the height of the moving roller 332.

[0059] When going uphill, the height of the detection roller 45 increases, the counterweight piston plate 47 is reset under the action of the return spring 48, the hydraulic oil flows back from the fixed outer sleeve to the detection groove 46, the moving inner rod retracts upward, raising the height of the moving roller 332.

[0060] Balance effect: By adjusting the height of the movable wheel set 33 in real time, and with the support of the fixed wheel set 32, the support plate 31 always remains horizontal, thereby ensuring that the charging pile body 1 is vertical and guaranteeing the stability and safety of the equipment operation.

[0061] 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.
