Description

TECHNICAL FIELD

[0002] When charging a new energy vehicle, the charging port needs to be opened, and a handheld charging gun is inserted into the vehicle charging port. Most fast charging guns are connected to power distribution cabinets or charging piles by cables, and the on-board charger is charged by directly inserting a household 220V power supply. Manual intervention is required for operation during the charging process. The weight of the charging gun and the heavy charging cable is more than 10kg during fast charging, which is laborious and inconvenient to carry. With the continuous updating and iteration of super charger technology, the current is increasing. In order to bear a larger current, the cross section of the cable needs to be set larger, resulting in heavier cables and charging guns, which are inconvenient to use. At the same time, since the size of the charging port is made according to the national standard, the metal cross-sectional area of the charging interface is fixed. If a higher current load is to be carried, a material with a lower resistance value is needed, and the price of the material with a lower resistance value will also be more expensive, such as precious metals silver and gold, which increases the overall cost. The high cost, the current carrying capacity limitation of the charging interface, the cumbersome charging process, and the high operation intensity of the charging process affect the application of super charging technology.

[0037] The specification can use phrases such as "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which can refer to one or more of the same or different embodiments according to the present application.

[0038] Figures 1 to 4 The structural schematic diagram of the charging device of the electric vehicle provided by the embodiments of the application is shown. As shown in the figure, Figures 1 to 4 The first embodiment of the application provides a charging device for an electric vehicle, comprising:

[0039] The charging pile comprises a column 1 and a charging machine 2 installed on the top of the column 1, the charging machine 2 comprises a track plate 21, an adjusting sliding block 22, a cantilever 23, a swing assembly 24, a driving mechanism and a first electrode 25, the track plate 21 is installed on the top of the column 1, the adjusting sliding block 22 is movably installed on the track plate 21 and connected with the cantilever 23, one end of the swing assembly 24 is connected with the cantilever 23, the other end of the swing assembly 24 is connected with the first electrode 25, and the driving mechanism is connected with the adjusting sliding block 22;

[0040] The second electrode 3 is installed on the top of the vehicle and connected with the battery 20 of the vehicle.

[0041] The vehicle in the application is an electric vehicle. Specifically, the track plate 21 is transversely arranged at the front end of the top of the column 1, the track plate 21 is provided with a transversely arranged sliding rail, one end (rear end) of the adjusting sliding block 22 is slidably connected with the sliding rail, the other end (front end) of the adjusting sliding block 22 is connected with the cantilever 23, and the cantilever 23 is connected with the first electrode 25 through the swing assembly 24.

[0042] After the vehicle is parked in the parking position, the charging machine 2 is located above the vehicle. The driving mechanism drives the adjusting slider 22 to move along the sliding rail on the rail plate 21 according to the lateral position of the second electrode 3 on the top of the vehicle, drives the cantilever 23 connected with the adjusting slider 22 to move, adjusts the lateral position of the cantilever 23, and further adjusts the lateral position of the first electrode 25 connected with the cantilever 23. After the lateral position of the cantilever 23 is adjusted, the swing assembly 24 swings the first electrode 25 according to the relative position of the second electrode 3 and the first electrode 25, so that the first electrode 25 and the second electrode 3 on the top of the vehicle are connected in contact, and then the vehicle battery 20 connected with the second electrode 3 is charged through the charging pile. After the charging is completed, the swing assembly 24 first operates to make the first electrode 25 and the second electrode 3 disengage, and then the driving mechanism is controlled to work to drive the adjusting slider 22 to move to the initial position.

[0043] The relative position of the second electrode 3 and the first electrode 25 can be the height between the second electrode 3 and the first electrode 25, the lateral distance (left-right distance) between the second electrode 3 and the first electrode 25, and the longitudinal distance (front-rear distance) between the second electrode 3 and the first electrode 25. Since the position of the second electrode 3 on the top of the vehicle is fixed, in the embodiment, the lateral position of the first electrode 25 can be adjusted according to the width of the vehicle first, and then the position of the first electrode 25 is fine-tuned according to the position error between the first electrode 25 and the second electrode 3, so that the first electrode 25 and the second electrode 3 can be reliably contacted. The adjusting slider 22 (adjusting the lateral position) and the swing assembly 24 (adjusting the longitudinal position and the lateral position) can adjust the position of the first electrode 25 from different directions according to the position of the second electrode 3 on the top of the vehicle.

[0044] The charging device of the electric vehicle provided by the embodiment of the application comprises a charging pile and a charging machine 2 installed on the top of the charging pile 1, the charging machine 2 comprises a track plate 21, an adjusting sliding block 22, a cantilever 23, a swing assembly 24, a driving mechanism and a first electrode 25, the track plate 21 is installed on the top of the charging pile 1, the adjusting sliding block 22 is movably installed on the track plate 21 and connected with the cantilever 23, one end of the swing assembly 24 is connected with the cantilever 23, the other end of the swing assembly 24 is connected with the first electrode 25, the driving mechanism is connected with the adjusting sliding block 22, and a second electrode 3 connected with a vehicle battery 20 is installed on the top of the vehicle, after the vehicle is parked in the parking position, the adjusting sliding block 22 can be driven to move along the track plate 21 by the driving mechanism, the lateral position of the first electrode 25 is adjusted, at the same time, the position of the first electrode 25 is further adjusted by swinging of the swing assembly 24, so that the first electrode 25 and the second electrode 3 on the top of the vehicle are reliably matched for charging, and the charging reliability and the charging effect are improved; in addition, the adjusting sliding block 22, the cantilever 23, the swing assembly 24 and the first electrode 25 are sequentially connected, the structure is reasonable, the position of the first electrode 25 can be accurately adjusted by two position adjustments in sequence, the adjustment is convenient and fast, and the charging efficiency is improved.

[0045] The charging electrode of the charging machine 2 automatically falls to connect the charging electrode on the top of the vehicle for charging, the whole charging process does not need manual operation of the charging gun, and the whole charging process can be completed without the driver getting off the vehicle; when the electric vehicle is charged, the parking mode is not limited, the vehicle can be reversed into the garage or the vehicle head can be parked in the garage; the above charging device is friendly to novice drivers, the position of the first electrode 25 can be automatically adjusted by using the adjusting sliding block 22 and the swing assembly 24, and the vehicle does not need to be accurately parked in the charging position. As known from the above, the charging device is convenient for charging, has high automation degree, low cost and wide application range. In addition, in the application, the charging electrode is used to replace the charging interface with a certain cross-sectional area, can bear higher current load, and has low cost.

[0046] In some embodiments, the driving mechanism comprises a driving motor and an adjusting screw, the adjusting screw is installed on the track plate 21, and the driving motor and the adjusting sliding block 22 are respectively sleeved on the adjusting screw. The driving motor and the adjusting sliding block 22 are in transmission connection with the adjusting screw, when the driving motor works, the adjusting screw is driven to rotate, the adjusting screw drives the adjusting sliding block 22 to move along the track plate 21, so as to adjust the lateral position of the cantilever 23. The adjusting screw transmits power as a transmission member, and can also guide the movement of the adjusting sliding block.

[0047] In some embodiments, as Figures 2 to 4As shown, the second electrode 3 is two, which are respectively arranged on the left and right sides of the top of the vehicle, the adjusting slider 22 includes a first adjusting slider 221 and two second adjusting sliders 222, the second adjusting slider 222 is respectively arranged on the left and right sides of the first adjusting slider 221, the driving motor includes a first driving motor 261 and a second driving motor 262, the adjusting screw includes a first adjusting screw 271 connected with the first driving motor 261 and a second adjusting screw 272 connected with the second driving motor 262, the two second adjusting sliders 222 and the second driving motor 262 are respectively sleeved on the second adjusting screw 272, and the second driving motor 262 is located at the middle position of the two second adjusting sliders 222, the second driving motor 262 is also connected with the first adjusting slider 221, the cantilever 23 is two, which are respectively connected with the two second adjusting sliders 222 in correspondence, and the track plate 21 is provided with a first sliding rail 211 slidably connected with the first adjusting slider 221 and a second sliding rail 212 slidably connected with the second adjusting slider 222.

[0048] In the embodiment, one second electrode 3 can be arranged on the left and right sides of the top of the vehicle, and correspondingly, one first electrode 25 is arranged on the left and right sides of the charging machine 2. In order to ensure the adjusting accuracy and facilitate the adjustment of the positions of the two first electrodes 25, the first adjusting slider 221 and the two second adjusting sliders 222 located on the left and right sides of the first adjusting slider 221 are arranged, each second adjusting slider 222 is connected with a cantilever 23, and each cantilever 23 is connected with a first electrode 25 through a swing assembly 24.

[0049] After the vehicle is parked and positioned, the first driving motor 261 drives the first adjusting slider 221 to move along the first sliding rail 211, so that the first adjusting slider 221 moves to the middle position of the two second electrodes 3 on the top of the vehicle body. Since the second driving motor 262 is connected with the first adjusting slider 221, the second driving motor 262 moves to the middle position of the two second electrodes 3. At this time, the second driving motor 262 works to drive the two second adjusting sliders 222 sleeved on the second adjusting screw 272 to move respectively, so as to adjust the transverse positions of the two first electrodes 25, so that the transverse positions of the two first electrodes 25 are roughly aligned with the transverse positions of the two second electrodes 3. Since there may be a certain deviation in the relative positions of the first electrode 25 and the second electrode 3, the corresponding first electrode 25 is adjusted through the two swing assemblies 24 at this time.

[0050] Through the first adjusting slider 221 and the two second adjusting sliders 222, the first adjusting slider 221 is first moved to the middle position of the two second electrodes 3 by the first driving motor 261, and then the two first electrodes 25 are moved to the positions corresponding to the two second electrodes 3 by driving the two second adjusting sliders 222 to move synchronously by the second driving motor 262 with the first adjusting slider 221 (or the second driving motor 262) as the adjusting center, so that the synchronous adjustment of the positions of the two first electrodes 25 can be realized, and the accuracy of the position adjustment is ensured.

[0051] In some other embodiments, the first driving motor 261, the first adjusting slider 221 and the first sliding rail 211 are not provided, and two second driving motors 262 are provided, each of which is connected with a second adjusting slider 222, that is, the positions of the two first electrodes 25 are adjusted respectively by the different second driving motors 262 driving the different second adjusting sliders 222 respectively. In order to avoid adjustment interference, a second adjusting screw 272 needs to be provided for each second driving motor 262.

[0052] In the structure in which the two second driving motors 262 drive the two second adjusting sliders 222 respectively, the position of each first electrode 25 needs to be adjusted according to the position of each second electrode 3. In the structure in which the first adjusting slider 221 and the two second adjusting sliders 222 cooperate, the position of each second electrode 3 does not need to be determined specifically, for example, only the distance between the two second electrodes 3 needs to be known. For vehicles of different widths, the distance between the two second electrodes 3 is determined relative to the specific position of the two second electrodes 3 (for example, the position of the second electrode 3 on the top of the vehicle needs to be determined according to different vehicle models), which is convenient to determine and can effectively improve the position adjustment efficiency of the first electrode 25.

[0053] In some embodiments, the first adjusting screw 271 and the second adjusting screw 272 are relatively parallel in the up-down direction, and the first sliding rail 211 and the second sliding rail 212 are relatively parallel in the up-down direction.

[0054] The first adjusting screw 271, the second adjusting screw 272, the first sliding rail 211 and the second sliding rail 212 are arranged at different heights on the track plate 21, for example, in the embodiment, the first sliding rail 211 and the second sliding rail 212 are arranged on the plate surface of the track plate 21 respectively, and the first sliding rail 211 is above the second sliding rail 212, so that the first adjusting slider 221 and the second adjusting slider 222 at different heights can move smoothly. The first adjusting screw 271 is preferably arranged above the top of the track plate 21, and is arranged close to the first sliding rail 211 in the height direction. A first driving motor 261 is installed at one end of the top of the track plate 21, and is sleeved on the first adjusting screw 271 and in transmission connection with the first adjusting screw 271. The first adjusting slider 221 is also sleeved on the first adjusting screw 271 and in transmission connection with the first adjusting screw 271. Since the first adjusting slider 221 moves near the middle position of the two second electrodes 3, the length of the first adjusting screw 271 can be set to be greater than half of the length of the track plate 21, thereby reducing the overall weight of the charging machine 2. The second adjusting screw 272 is preferably arranged below the front side of the second sliding rail 212, that is, the second adjusting screw 272 is connected with the two second adjusting sliders 222 and the second driving motor 262, the second driving motor 262 is connected with the first adjusting slider 221, and the movement of the second adjusting slider 222 along the second sliding rail 212 is not affected. The overall structure of the charging machine 2 is compact and reasonable, and the position of the first electrode 25 can be adjusted conveniently.

[0055] In the embodiment, one second electrode 3 is arranged on each of the left and right sides of the top of the vehicle, and one first electrode 25 is arranged on each of the left and right sides of the charging machine 2, corresponding to the second electrode 3. Two groups of first electrodes 25 and second electrodes 3 can be used to charge at the same time, thereby improving the charging efficiency. When one group of first electrodes 25 and second electrodes 3 is in poor contact (for example, the exposed second electrode 3 is rusty or adhered with other objects), the other group of first electrodes 25 and second electrodes 3 can be used to effectively charge.

[0056] In specific implementation, the charging device can also be provided with only one group of first electrodes 25 and second electrodes 3, for example, one second electrode 3 is arranged at the middle of the vehicle in the width direction, the first sliding rail 211 is arranged on the track plate 21 of the charging machine 2, the first adjusting slider 221 is in sliding connection with the first sliding rail 211, the first adjusting slider 221 is connected with the first driving motor 261 through the first adjusting screw 271, the front end of the first adjusting slider 221 is connected with a cantilever 23, and the cantilever 23 is connected with the first electrode 25 through a swing rod 24. This can reduce the parts of the charging machine 2, reduce the cost of the charging machine 2, and be suitable for vehicle models with small charging current or charging power.

[0057] In some embodiments, as Figure 3 andFigure 4 As shown, the swing assembly 24 comprises a swing rod 241 and a telescopic rod 242, one end of the swing rod 241 is connected with the adjusting slider 22 through a first rotating shaft 243, the other end of the swing rod 241 is connected with the first electrode 25 through a second rotating shaft 244, one end of the telescopic rod 242 is connected with the cantilever 23 through a third rotating shaft 245, the other end of the telescopic rod 242 is connected with the rod body of the swing rod 241 through a fourth rotating shaft 246.

[0058] The telescopic rod 242 is vertically arranged between the cantilever 23 and the first electrode 25, the swing rod 241 is inclined relative to the telescopic rod 242, the telescopic rod 242 can be telescoped along its axis, so that the first electrode 25 moves outwards to contact the second electrode 3 below, or retracts upwards to be separated from the second electrode 3; at the same time, the position of the first electrode 25 can be finely adjusted through the swing of the swing rod 241 to ensure reliable contact with the second electrode 3. When the telescopic rod 242 is telescoped, the swing rod 241 can swing with the telescopic rod 242. The swing rod 241, the telescopic rod 242 and the cantilever 23 cooperate to form a triangular structure, which has good stability and further ensures the charging reliability. In addition, the swing of the swing rod 241 can be limited within a certain range by swinging the swing rod 241 through the telescopic rod 242, so as to avoid arbitrary swing of the swing rod 241.

[0059] In specific implementation, the swing assembly 24 can also only comprise the swing rod 241, the swing rod 241 can be movably connected with the cantilever 23 through two rotating shafts arranged in cross, one of which is used for swinging in the front-rear direction (longitudinal direction) of the vehicle, and the other is used for swinging in the left-right direction (transverse direction) of the vehicle, so as to finely adjust the position of the first electrode 25. At this time, an additional limiting mechanism can be needed to limit the swing rod 241 after swinging.

[0060] Further, as shown in Figure 3 and Figure 4 The first electrode 25 has a plurality of connecting surfaces facing the second electrode 3, which facilitates the face-to-face contact connection between the first electrode 25 after swinging and the second electrode 3 by using different connecting surfaces, increases the connecting area, and ensures the charging reliability. For example, in the embodiment, the second electrode 3 is arranged as a concave structure comprising a bottom surface and two inclined surfaces on both sides of the bottom surface, so that any one of the connecting surfaces of the first electrode 25 after swinging can be in full contact with the second electrode 3, avoiding poor contact of the charging electrode.

[0061] In some embodiments, the charging pile further comprises a distribution box 4 mounted on one side of the column 1, the distribution box 4 is connected with the first electrode 25 through the first cable 5, the first cable 5 passes through the column 1 from bottom to top and is connected with the first electrode 25, and the distribution box 4 is also connected with the driving mechanism and the swing assembly 24 respectively.

[0062] The power distribution box 4 is provided with a first charging controller (not shown in the figure). When the vehicle enters the charging position, the vehicle parking related information can be transmitted to the first charging controller. The first charging controller analyzes the vehicle parking related information, determines whether the position of the first electrode 25 needs to be adjusted, and outputs the position adjustment instruction to the first driving motor 261 and the second driving motor 262 when adjustment is needed. The first driving motor 261 starts working after receiving the first position adjustment instruction, drives the first adjusting slider 221 to move along the first sliding rail 211 to the middle position of the two second electrodes 3. Then, the second driving motor 262 works after receiving the second position adjustment instruction, drives the second adjusting slider 222 to move along the second sliding rail 212 to the position corresponding to the second electrode 3.

[0063] The first charging controller can send a third position adjustment instruction to the swing assembly 24 to control the extension and retraction of the telescopic rod 242, and the up and down swing of the swing rod 241 along the first rotating shaft 243, thereby driving the first electrode 25 to swing up and down until the first electrode 25 contacts the second electrode 3, and then stopping the swing to determine that the first electrode 25 and the second electrode 3 are in reliable contact. After the first electrode 25 and the second electrode 3 are connected, the first charging controller can determine the positive and negative poles of the second electrode 3 on the left and right sides of the vehicle body through the polarity of the connected charging electrode (the first electrode 25), and start charging after determining that the first electrode 25 is consistent with the second electrode 3 of the vehicle body.

[0064] After the whole vehicle charging is completed, or the vehicle user sends a stop charging instruction to the first charging controller, the first charging controller can control the swing assembly 24, the first driving motor 261 and the second driving motor 262 to work, so that the telescopic rod 242, the first adjusting slider 221 and the second adjusting slider 222 return to the initial position, for example, the telescopic rod 242 is in the retracted state, and the first electrode 25 and the second electrode 3 are separated and powered off.
