Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging equipment technology, specifically a new energy vehicle charging device that can be raised, lowered, and floated for plugging in. Background Technology

[0002] With the increasing popularity of new energy vehicles and the growing demand for automation in charging stations, automatic plug-in charging devices are being widely used. These devices can autonomously align, plug in, and lock the charging connector to the vehicle's charging port without manual intervention, improving the convenience and operational efficiency of the charging process. They are suitable for charging scenarios involving passenger vehicles, freight vehicles, and many other types of vehicles. Currently, most automated charging piles use a rigid connection between the charging connector and the pile body, maintaining the connection through a locking mechanism after docking.

[0003] However, in actual use at charging stations, even after the vehicle engages parking brake, unavoidable changes in vehicle posture still occur. For freight vehicles, loading or unloading cargo alters the overall vehicle load, causing suspension compression or rebound, leading to multi-dimensional posture shifts at the charging port. Passenger vehicles also experience suspension deformation when passengers get on or off. Simultaneously, the operation of surrounding equipment and ground vibrations are transmitted to the vehicle body, causing minor, unpredictable swaying. Existing rigid connection structures cannot buffer the tension and torque generated by these posture shifts, easily causing charging port detachment and connector wear and damage. Conventional spring-type buffer structures can only provide buffering in limited directions and generate rebound reaction forces, making them unsuitable for handling the aforementioned unpredictable and variable-amplitude vehicle posture disturbances. Their protective effect on the charging port is limited, making it difficult to guarantee the stability of the charging process and the lifespan of the connectors. Summary of the Invention

[0012] Preferably, a sliding groove is provided on one side of the pusher frame, the plug base is slidably connected to the middle of the pusher frame, and a return spring is fixedly connected to both sides of the inner wall of the sliding groove.

This invention addresses the core pain points of existing automated charging piles, such as rigid charging interfaces that cannot adapt to the multi-directional and variable amplitude swaying of vehicles, which leads to easy damage to the interfaces due to tension and torsion and poor charging stability. It proposes an invention concept of a split charging pile body combined with a flexible air cushion buffer.

It improves charging stability from the structural root. 3. This invention enables dual-state switching of the floating platform by setting a locking docking column and an air supply operation. During the docking phase, rigid locking ensures the insertion accuracy, while during the charging phase, unlocking and floating achieves displacement buffering. The cam friction locking structure of the insertion ejection component, combined with the asymmetrical damping air inlet, balances the insertion thrust transmission efficiency and optimizes the motion resistance during the floating phase, forming an omnidirectional displacement buffering system and improving the operational stability of the device.

[0018] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] Example 1 Existing automated charging piles (201) typically lock the charging head after it connects to the vehicle's charging interface, resulting in a fixed connection. However, during the charging process of existing new energy vehicles, the vehicle body can still experience suspension compression or rebound due to changes in overall vehicle load, causing multi-dimensional attitude shifts in the charging port. Simultaneously, the operation of surrounding equipment and ground vibrations can also be transmitted to the vehicle body, resulting in unpredictable minor undulations, swaying, or displacement. This swaying and displacement is not only horizontal but also includes simultaneous lifting movements. These movements, which are unpredictable in direction, timing, and amplitude, can easily cause the charging interface to detach under tension or torque, or damage the interface structure, resulting in insufficient charging stability and structural durability.

[0020] like Figures 1 to 8In this embodiment, the new energy vehicle charging device with lifting and floating plug-in capability includes a platform 101, a charging pile 201 on one side of the platform 101, and a drive mechanism for moving the charging pile 201. The charging pile 201 includes a fixed pile body and a floating pile body. The fixed pile body is equipped with a lifting component for driving the overall lifting and lowering movement of the floating pile body. The lifting component can be implemented using existing mature equipment such as a lifting cylinder. The floating pile body includes a floating platform. A mounting frame 203 is fixedly connected to the top of the floating platform. A plug-in ejection component is slidably arranged inside the mounting frame 203. A charging connector 204 is provided at the output end of the plug-in ejection component. The floating platform includes a top plate 205 and a bottom plate. A floating air cushion 202 is provided between the top plate 205 and the bottom plate. An opening for cables to pass through is provided in the middle of the floating platform. A flexible sleeve 206 is fixedly connected to the inner wall of the opening. The bottom of the top plate 205 is fixedly connected to the bottom of the mounting frame 203.

[0021] The drive mechanism is used to achieve the overall flipping and translation operation of the charging pile 201. Its specific structure can be implemented with reference to existing technical means. In this embodiment, the drive mechanism includes a storage slot 105. A drive slide 102 is fixedly connected to the bottom of the inner wall of the storage slot 105. A slide seat 103 is slidably installed on the inner wall of the drive slide 102. A flipping motor is fixedly installed on one side of the slide seat 103. A flipping frame 104 is fixedly connected to the output end of the flipping motor. One side of the flipping frame 104 is fixedly connected to the charging pile 201. A closing cover 106 is slidably connected to one side of the inner wall of the storage slot 105. In order to realize the automatic pushing and retraction of the closing cover 106, a push motor is fixedly connected to both sides of the closing cover 106. A push guide wheel is fixedly connected to the output end of the push motor. The push guide wheel is in close contact with the edge of the closing cover 106. The closing cover 106 is used to cover the storage slot 105 when not in use to prevent dust and debris from falling into the storage slot 105 and affecting the operation of the device.

[0022] How the Floating Air Cushion 202 and its Infrastructure Work: Figures 7-8 The floating air cushion 202 can support the multi-directional displacement deformation of the top plate 205 and the upper structure, buffering the tension and torque caused by vehicle shaking, and preventing the force from being directly transmitted to the connection position between the charging connector 204 and the vehicle; the drive slide 102 can drive the charging pile 201 to move horizontally to adjust the docking distance, and the flip motor can drive the charging pile 201 to flip and adjust its posture to adapt to the charging port position of different models; when not in operation, the charging pile 201 can be stored in the storage slot 105, and the closed cover 106 closes to achieve full-enclosure protection and keep the surface of the platform 101 flat.

[0023] It should be emphasized that this embodiment adopts a separate structure of fixed pile body and floating pile body, and uses floating air cushion 202 as the core buffer element to replace the traditional rigid connection structure. Compared with the conventional mechanical buffer structure, which can only achieve buffering in certain specific directions and has rebound reaction force, this application can achieve multi-directional displacement compensation without rebound reaction force, fundamentally solving the core problem that fixed charging interface is easily damaged by tension and torsion; at the same time, it adopts an integrated storage and drive architecture of platform 101, which takes into account both position and posture adjustment capability and closed protection performance.

[0024] It should be noted that the port provides a built-in routing channel for the charging cable and control circuit, keeping the circuit inside the device throughout and avoiding external wear; the flexible sleeve 206 can elastically deform with the displacement of the floating platform, sealing the gap of the port to block dust and moisture, without restricting the freedom of movement of the floating platform, and protecting the cable from friction damage.

[0025] Example 2 It is understandable that, in Embodiment 1, although the flexible structure of the floating air cushion 202 can achieve displacement buffering during the charging stage, it directly results in the lack of rigid constraint on the floating platform and the charging connector 204 above during the insertion and docking stage. During the stage when the driving mechanism drives the charging pile 201 to move and dock with the charging interface, the position of the charging connector 204 is prone to horizontal displacement, twisting and shaking, which makes it impossible for the displacement adjustment of the driving mechanism and the insertion thrust to be accurately transmitted to the charging connector 204, and the positioning accuracy of automatic insertion cannot be guaranteed.

[0026] like Figure 5 , Figures 7 to 8 To address the aforementioned issues, the base plate has several mating interfaces in its center. A mating sleeve 209 is fixedly connected to the bottom of each interface, and the bottoms of these mating sleeves 209 are connected to a common air supply pipe 212. One end of the air supply pipe 212 is fixedly connected to the output end of an air pump. The bottom of the top plate 205 has several mating posts 207 fixedly connected, each corresponding to one of the mating interfaces. A locking push rod 210 is fixedly installed on one side of each mating sleeve 209, and a locking block 211 is fixedly connected to the output end of the locking push rod 210. A locking groove 208 is provided at the bottom of the side wall of each mating post 207, and the locking block 211 corresponds to the locking groove 208. The top of the inner cavity of the docking column 207 is provided with a flow guide cavity, the top of which is connected to the inside of the mounting bracket 203. A flow divider 213 is provided on the bottom side of the flow guide cavity, and a flow guide spring is fixedly connected inside the flow divider 213 and inclined to the inside of the flow guide cavity.

[0027] The working principle of floating platform switching: Figure 8During the insertion and docking phase, the docking post 207 is inserted into the docking interface, and the locking push rod 210 drives the latching block 211 to engage with the locking slot 208, making the top plate 205 and the bottom plate rigidly locked together. The floating platform returns to a rigid whole, ensuring docking positioning accuracy. After the charging connector 204 is inserted into place, the locking push rod 210 retracts and unlocks, the air pump starts and supplies air to the docking sleeve 209 through the air supply pipe 212, lifting the docking post 207 upward to disengage it from the docking interface. At the same time, the floating air cushion 202 is inflated, and the floating platform enters a free-floating state. Please refer to the status at this time. Figure 7 The flow guide cavity and flow divider 213 structure opened at the top of the inner cavity of the docking column 207 allow some airflow to be guided into the mounting bracket 203 through the flow divider 213 and the flow guide cavity, so as to achieve air cooling for the internal electrical components.

[0028] It should be emphasized that this embodiment addresses the inherent defect in docking accuracy caused by the flexible air cushion in Embodiment 1. Through the insertion and engagement of the docking post 207 with the docking interface and the active locking of the locking push rod 210, the floating platform achieves dual-state switching between rigid docking and flexible floating during charging. While retaining the advantages of floating buffering, it completely solves the landing problem of insufficient docking accuracy in flexible floating structures. Furthermore, the unlocking drive and air cushion inflation are completed simultaneously using the same air supply system, resulting in a simplified and efficient structure. The configured airflow structure can reuse the air supply source for component heat dissipation, eliminating the need for additional heat dissipation components and improving air source utilization and device operational stability.

[0029] It should be noted that the multiple sets of docking posts 207 are symmetrically distributed with the docking interface, which can limit the horizontal translation and torsion of the floating stage and effectively improve the success rate of automatic insertion.

[0030] It should be noted that the inclined guide blades inside the guide cavity create a one-way conduction effect, allowing airflow to enter the mounting bracket 203 in the forward direction for heat dissipation.

[0031] Example 3 It is understandable that in Embodiment 2, only the dual-state locking and releasing of the floating platform as a whole is realized, but the state constraint of the plug-in ejection component inside the mounting bracket 203 is not applied: During the docking phase, the plug-in ejection component can slide freely along the mounting bracket 203. When the charging connector 204 is pushed, the movable base 301 will be pushed backward by the reaction force, which will cause the plug-in thrust to be unable to be effectively transmitted, the plug insertion depth to be insufficient, and the docking reliability to be greatly reduced; During the charging floating phase, the plug-in ejection component needs to move forward and backward with the vehicle, but the cavity of the mounting bracket 203 is relatively closed. When the component moves backward, the air in the rear cavity is compressed to form a large damping. If the vehicle moves slightly too much, it will pull the charging connector 204 and cause it to detach.

[0032] like Figures 6 to 7To address the aforementioned issues, the plug-in ejection assembly includes a movable base 301. An electric push rod 302 is fixedly mounted in the center of the movable base 301. A pusher frame 303 is fixedly connected to the output end of the electric push rod 302. A plug base 305 for mounting a charging plug is provided on one side of the pusher frame 303. A positioning motor 307 is fixedly mounted in the center of the movable base 301. A positioning cam 308 is fixedly connected to the output end of the positioning motor 307. A friction pad is fixedly connected to the outer wall of the positioning cam 308. The friction pad increases the friction between the cam and the inner wall of the mounting frame 203, improving locking reliability and preventing component wear caused by rigid contact. Several air inlets 214 are provided at the end of the mounting frame 203 furthest from the charging plug. Air inlet vanes 215, inclined towards the inner cavity of the mounting frame 203, are fixedly connected to the inner walls of each air inlet 214. The inclined air inlet vanes 215 form a bent flow channel, preventing dust and splashing moisture from directly entering the mounting frame 203, thus improving the protection level of internal electrical components.

[0033] The working principle of the dual-state switching of the plug-in ejection component: During the plug-in stage, the positioning motor 307 drives the positioning cam 308 to rotate, pressing the inner wall of the mounting bracket 203 with the friction pad, so that the movable base 301 is relatively fixed with the mounting bracket 203, ensuring that the plug-in thrust of the electric push rod 302 is effectively transmitted; During the charging and floating stage, the positioning motor 307 drives the positioning cam 308 to rotate and release, and the movable base 301 can slide freely along the mounting bracket 203, moving forward and backward with the vehicle; The inclined air intake fins 215 make the exhaust and intake resistance of the mounting bracket 203 asymmetrical. When the component moves backward to exhaust, the resistance is small, and it can smoothly follow the vehicle away. When the component moves forward to intake, the resistance is large, which can buffer the impact force of the vehicle approaching.

[0034] It should be emphasized that, in order to address the functional deficiency of only constraining the floating platform as a whole in Embodiment 2, this embodiment extends the constraint object of the dual-state switching from the entire floating platform to the plug-in ejection assembly. Through the friction locking structure formed by the positioning cam 308 and the friction pad, the synchronous dual-state switching of the plug-in ejection assembly and the floating platform is realized. During docking, the locking ensures the plug-in thrust and alignment accuracy, and during charging, the locking releases the assembly to allow free floating in the front and rear directions. In conjunction with the inclined air inlet 215, a bidirectional asymmetric damping is formed to optimize the motion resistance characteristics during the floating stage, further preventing the charging connector 204 from being pulled out, and at the same time buffering the impact force of the approaching vehicle to protect the interface structure.

[0035] Example 4 Based on Example 3, in order to further improve the planar displacement compensation capability, orthogonally complete the buffer degrees of freedom in the left and right directions, and enhance the adaptability of the device to multi-directional composite swaying scenarios, the following extended improvements are made.

[0036] like Figure 6A sliding groove is provided on one side of the pusher 303, and the plug base 305 is slidably connected to the middle of the pusher 303. A return spring 304 is fixedly connected to both sides of the inner wall of the sliding groove. Both return springs 304 are fixedly connected to the plug base 305. One side of the plug base 305 is fixedly connected to the charging plug. Push blocks 306 are fixedly connected to both sides of the inner wall of the mounting bracket 203. One side of the two push blocks 306 is set as an inclined surface. The two ends of the pusher 303 are respectively set to correspond to the two push blocks 306.

[0037] It should be emphasized that this embodiment is an extension and supplement to the buffer degree of freedom. The sliding plug base 305, together with the return spring 304, absorbs the force of lateral displacement of the vehicle and forms an independent and non-interfering planar compensation system with the front and rear floating buffer, which can jointly adapt to planar displacement in any direction.

[0038] It should be noted that the reset spring 304 can provide flexible buffering during charging to absorb lateral impact force, and can also drive the plug base 305 to automatically reset to the center of the sliding groove after the plug is unplugged at the end of charging, so as to prepare for the next docking.

[0039] It should be noted that during insertion, the plug base 305 is pushed out to be misaligned with the push block, thereby allowing the charging connector 204 to slide freely left and right, which can adapt to the left and right position deviation of the vehicle charging port and reduce the alignment accuracy requirements.

[0040] The working principle of the device is as follows: In standby mode, the charging pile 201 is stored inside the storage slot 105 of the platform 101, and the closed cover 106 closes to cover the opening of the storage slot 105; the docking column 207 of the floating platform is inserted into the docking interface of the base plate, and the locking push rod 210 drives the locking block 211 to engage with the locking slot 208 on the side wall of the docking column 207, and the top plate 205 and the base plate are rigidly locked together; the positioning motor 307 inside the mounting frame 203 drives the positioning cam 308 to rotate, and presses the inner wall of the mounting frame 203 with the friction pad, and the movable base 301 and the mounting frame 203 remain relatively fixed. After the vehicle is parked, the push motor drives the push guide wheel to rotate, causing the closed cover 106 to slide open along the inner wall of the storage slot 105; the flip motor drives the flip frame 104 to rotate, flipping the charging pile 201 from the storage slot 105 and standing it up; the drive slide 102 drives the sliding seat 103 to move horizontally along the slot, adjusting the lateral docking distance between the charging pile 201 and the vehicle; the lifting component inside the fixed pile body drives the floating pile body to move up and down, so that the charging connector 204 corresponds to the position of the vehicle's charging port; After alignment, the electric push rod 302 pushes the pusher 303 forward, causing the charging connector 204 to move closer to the vehicle charging port. During the forward movement of the pusher 303, the plug base 305 remains aligned until the plug base 305 disengages from the two side push blocks 306. At this time, the plug base 305 slides horizontally along the pusher plate, which facilitates the final stage of the charging connector 204 being inserted into the vehicle charging port to complete the connection. After the docking is confirmed, the locking push rod 210 drives the snap block 211 to retract, releasing the mechanical lock between the top plate 205 and the bottom plate; the air pump starts, and the airflow is distributed to each docking sleeve 209 through the air supply pipe 212, lifting the docking column 207 upward to disengage the docking column 207 from the docking interface. At the same time, the airflow fills the floating air cushion 202 between the top plate 205 and the bottom plate, making the air cushion full. The floating platform enters a free floating state and can move in multiple directions with the vehicle's movement; part of the airflow enters the guide cavity through the diversion port 213 on the side wall of the docking column 207, and is guided upward into the mounting bracket 203, flowing through the internal electrical components. Synchronously, the positioning motor 307 drives the positioning cam 308 to rotate and release, the movable base 301 is released from friction lock and can slide freely along the inner wall of the mounting bracket 203; the air inlet 214 at the end of the mounting bracket 203 away from the charging plug, together with the inclined air inlet 215, forms asymmetrical airflow damping, the movable base 301 has less resistance when it moves backward to exhaust air, and greater resistance when it moves forward to intake air; the plug base 305 can slide left and right along the sliding groove of the pusher 303, and the return springs 304 on both sides deform accordingly with the sliding of the plug base 305; After charging is completed, the electric push rod 302 drives the push frame 303 to retract backward, the charging connector 204 is pulled out of the vehicle's charging port, the air pump stops supplying air, the floating air cushion 202 gradually depressurizes, the top plate 205 resets under gravity, the drive slide 102 drives the sliding seat 103 back to its initial position, the flip motor drives the flip frame 104 to rotate in the opposite direction, and the charging pile 201 is laid down and stored inside the storage slot 105; at this time, the floating pile body and the end of the storage slot 105 push together, so that the docking post 207 is re-inserted into the corresponding docking interface; the positioning motor 307 drives the positioning cam 308 to rotate again, pressing the inner wall of the mounting frame 203 with the friction pad, and locking the movable base 301 again; finally, the push motor drives the push guide wheel to rotate in the opposite direction, driving the closing cover 106 to slide and close, covering the opening of the storage slot 105 again, and the device returns to the standby state.
