Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of new energy vehicles, and relates to a charging technology of a new energy vehicle, in particular to an automatic interaction control method of a charging pile. BACKGROUND

[0002] With the development of new energy vehicles, the proportion of new energy vehicles is getting higher and higher, and the demand for charging piles is getting more and more vigorous. At present, the charging pile basically has one charging pile and one charging gun matched with one parking space, but the phenomenon of new energy parking spaces being occupied by fuel vehicles often occurs, resulting in that the charging pile becomes a decoration or has a low utilization rate.

[0003] For this phenomenon, a shared charging pile appears in the prior art. For example, the patent application with the application number 202110588619.9 discloses a mobile charging pile, which is arranged above the parking space. The charging package can move on the track. Specifically, it comprises an installation carrier and a charging package. The installation carrier is mainly used for installing the charging package and is used as a carrier during installation of the charging package. The installation carrier can be a power taking track. One end / side of the power taking track is fixedly installed on the ground, wall, stand or ceiling of the parking lot. The other end / side is installed with the charging package. The charging package can move on the power taking track along the length direction of the power taking track and stop at the position corresponding to the parking space according to the charging demand. When the user parks the vehicle, as long as the two-dimensional code corresponding to the parking space is scanned, the charging package will automatically move to the corresponding parking space for charging.

[0004] However, the invention patent and other prior arts have a common defect: there is only one track and only one charging package can be hung. Therefore, the patent application with the application number 202210834481.0 discloses a screw guide type closed loop mobile charging pile. The arc segment tracks and straight line segment tracks located at the corners of the guide rail are hung on the top of the garage wall, and a plurality of variable track gaps are left between them. The guide columns with sliding blocks of the variable track assembly of the variable track device are supported on the short side frames of the variable track frame body at both ends, the variable track guide rail with a connecting frame is installed on the sliding block, the electric push rod is hingedly connected to the push rod lug and the connecting frame at both ends, and the variable track device is installed in the variable track gap. The cable-wound take-up drum of the take-up device of the moving device is supported on the moving frame at both ends, the take-up drive on the moving frame is connected with the take-up roll, the guide rod and the guide screw with the guide assembly are supported on the moving frame of the moving device at both ends, the guide gear on the guide screw is engaged with the take-up gear of the take-up device, and the plurality of moving devices are hung on the guide rail through the moving assembly installed on the moving frame.

[0005] In the prior art, when the charging package is controlled to move, the user initiates a charging request, and then the system outputs a control command according to the charging request. The motor on the charging package starts and pushes the charging package to move on the guide rail after receiving the control command. However, when there are multiple charging packages on a track and multiple charging requests at the same time, how the charging packages move on the track and how to effectively avoid the movement conflict between the moving charging packages are necessary to provide a charging pile automatic interaction control method suitable for independent movement of multiple charging packages on a track. SUMMARY

[0019] When the direct current charging cabinet controls the charging bag to charge, if only one charging bag is charging, the charging bag charges at 100% charging power; if there are multiple charging bags, the first charging bag charges at 50% charging power according to the charging time from long to short, and the subsequent charging bag is half of the charging power of the previous charging bag.

[0020] Further, the charging device comprises a charging guide rail, a charging bag and a mounting frame, the charging bag is connected to the charging guide rail and can move along the direction of the charging guide rail, characterized in that: a notch is arranged on the charging guide rail corresponding to the position of each mounting frame, and a rail changing mechanism is arranged at the bottom of the mounting frame,

[0022] The charging bag is movably connected to the moving guide rail, and a driving mechanism for driving the first bevel gear to rotate is arranged on the charging bag.

[0023] The beneficial effects of the present application are as follows:

[0024] A charging pile automatic interaction control method, comprising a charging device, when the charging device charges, the control steps are:

[0025] Step S1, moving each charging bag to the moving guide rail of the rail changing mechanism which is not connected with the charging guide rail;

[0026] Step S2, according to the charging request, controlling the rail changing mechanism where the idle charging bag closest to the required charging position to push the moving guide rail where the charging bag is located to move and connect with the charging guide rail;

[0027] Step S3, controlling the charging bag to move to the specified position on the charging guide rail;

[0029] Step S5, the charging gun is output from the charging bag, and the charging gun is inserted into the charging interface on the vehicle to charge the vehicle; after charging is completed, the charging gun is collected and stored in the charging bag.

[0030] 1、In the present application, all charging bags before charging are on the mobile guide rail which is not connected with the charging guide rail, when there is a charging request and the corresponding rail changing mechanism works to push the charging bag into the charging guide rail, and when the charging bag moves on the charging guide rail, the remaining charging bags are on the mobile guide rail which is not connected with the charging guide rail, and will not hinder the movement of the charging bag, the charging bag can be moved to the corresponding charging position in time and efficiently, and can be separated from the charging guide rail under the action of the rail changing mechanism; effectively solve the problem that the movement of multiple charging bags on one track will affect each other, the whole charging movement process is not affected by other charging bags, and the efficiency of vehicle charging is higher.

[0031] 2、In the present application, the charging power is distributed by the direct current charging cabinet, if multiple charging bags are charged at the same time, according to the charging time from long to short (i.e. the order, the charging power of the first charging bag is higher), the first charging bag can be allocated 50% power, the second charging bag can be allocated 25% power, the third charging bag can be allocated 12.5% power, and so on, so that the vehicle that charges first can allocate more power, and the charging efficiency is higher, which can effectively solve the problem of charging position and charging gun occupation.

[0032] 3、In the present application, the rail changing mechanism is composed of a transverse guide rail, a mobile guide rail, a rail changing mechanism, a sliding wheel and the like, which has simple structure, easy manufacturing and low production cost; the rail changing frame is provided with a screw rod and a first bevel gear matched with the screw rod, the driving device on the charging bag can drive the first bevel gear to rotate through a transmission mechanism, and the first bevel gear, the mobile guide rail and the charging bag can move together through the thread connection of the first bevel gear and the screw rod, so that the charging bag needing maintenance or charging can be removed from the charging guide rail through moving the mobile guide rail, avoiding affecting the normal use of the charging device; and in this structure, it is very convenient and fast to move the mobile guide rail, and the failure rate is very low.

[0033] 4. In this invention, since the charging pack and the track-changing mechanism are driven by gear meshing, and during normal charging, the charging pack needs to travel between the charging guide rail and the track-changing mechanism, and when track changing is required, the track-changing mechanism will be driven by gear transmission to achieve track changing. This requires that the gear transmission mechanism is not prone to collision and that the gears do not collide when the charging pack travels between the charging guide rail and the track-changing mechanism. Therefore, a notch is provided on the second gear. When the charging pack travels between the charging guide rail and the track-changing mechanism, the notch on the second gear is opposite to the gear on the track-changing mechanism. The notch on the second gear can effectively avoid collision with the gear on the track-changing mechanism. When track changing is required, the second gear is rotated to achieve meshing between the second gear and the gear on the track-changing mechanism. That is, the second gear and the gear on the track-changing mechanism switch between "meshing-non-meshing-meshing-non-meshing-…-meshing-non-meshing-meshing-non-meshing". Attached Figure Description

DETAILED DESCRIPTION

[0044] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0046] The present embodiment provides a charging pile automatic interaction control method for charging control of a vehicle.

[0047] The control method needs to be matched with a charging device. When the vehicle is charged by using the charging device, the specific control steps are as follows:

[0048] Step S1, move each charging pack to the rail changing mechanism, and move the charging pack out of the charging guide rail 1 through the rail changing mechanism, so that the moving guide rail 32 where the charging pack is located is not connected with the charging guide rail 2.

[0049] Since each charging pack 2 is moved out of the charging guide rail 1 when it is idle, it will not affect the movement of other charging packs 2 moving on the charging guide rail 1.

[0050] Step S2, after the vehicle stops at the charging parking space, the driver or passenger initiates a charging request by scanning the two-dimensional code on the charging rail 2 (for details, please refer to the technical solution described in the 202211360889.5 invention patent application), and the charging system will control the idle charging pack 2 closest to the required charging parking space to work according to the charging request. At this time, the rail switching mechanism pushes the mobile rail 32 where the charging pack 2 is located to move, and the rail switching mechanism pushes the charging pack 2 into the charging rail 1, so that the mobile rail 32 where the charging pack 2 is located is connected with the charging rail 1.

[0051] Step S3, the system controls the driving motor on the charging pack 2 to work, drives the charging pack 2 to move on the charging rail 1, and finally stops after moving to the designated position.

[0052] Step S4, the system controls the rail switching mechanism to push the mobile rail 32 where the charging pack 2 is located to move, and pushes the charging pack 2 out of the charging rail 1. The rest of the mobile rail 32 of the rail switching mechanism is connected with the charging rail 1 and ensures that the entire charging rail 1 is through.

[0053] Step S5, the system controls the driving mechanism 201 in the charging gun to work, outputs the charging gun and charging cable from the charging pack 2, and stops outputting the charging cable after the charging cable is output for a certain distance. The driver or passenger inserts the charging gun into the charging interface on the vehicle to charge the vehicle. After charging is completed, the charging gun is collected and the charging cable and charging gun are stored in the charging pack 2, completing the charging of the vehicle.

[0054] When receiving other charging requests and the system controls the charging pack 2 to charge other vehicles, repeat the above steps to complete the charging of other vehicles.

[0055] In order to realize the communication between the charging pack 2 and the mobile rail 32, a network connection contact 6 is arranged on the mobile rail 32, and a network connector 5 is arranged on the charging pack 2. The network connector 5 is matched with the network connection contact 6. When the charging pack 2 moves to the mobile rail 32 and stops on the mobile rail 32, the network connection contact 6 is connected with the network connector 5 to realize information communication.

[0056] Since the charging pack 2 moves on the charging rail 1 and contacts the corresponding mobile rail 32, the network connector 5 on the charging pack 2 contacts the network connection contact 6 on the mobile rail 32. In order to avoid false communication between the network connection contact 6 and the network connector 5 during the normal movement of the charging pack 2, a contact time threshold can be set. When the network connection contact 6 and the network connector 5 are connected for more than the threshold, they are connected with each other and with the outside to realize information communication.

[0057] In order to facilitate the movement of the charging pack, the charging rail 1 is arranged as a ring rail, such as Figure 1As shown, the charging pack can move back and forth on the annular guide rail. The annular guide rail includes track one on the left side and track two on the right side, and the track one and the track two are connected end to end to form an annular structure. A plurality of charging positions are arranged on each track, and each charging position is provided with a track switching mechanism. In order to improve the utilization rate of the charging pack and avoid excessive idle of the charging pack, the number of charging positions on the charging guide rail is greater than the number of charging packs.

[0058] In addition, two direct current charging cabinets are also included, one of which is electrically connected with the track one on the left side, and the other is electrically connected with the track two on the right side.

[0059] The charging pack 2 moves to the moving guide rail 32 and stops on the moving guide rail 32, and the network connection contact 6, the network line joint 5 and the corresponding direct current charging cabinet are connected, and the direct current charging cabinet controls the corresponding charging pack 2 to charge or stop charging.

[0060] When the direct current charging cabinet controls the charging pack 2 to charge, if there is only one charging pack 2, the charging pack 2 charges at 100% charging power; if there are multiple charging packs 2, the first charging pack charges at 50% charging power according to the charging time from long to short, and the subsequent charging pack is half of the charging power of the previous charging pack.

[0061] The charging device includes a charging guide rail 1, a charging pack 2, a mounting frame 4, and a charging pack track switching mechanism. The charging pack 2 is installed on the charging guide rail 1 and can move along the track direction of the charging guide rail 1 to charge different new energy vehicles. Since the charging device is a shared charging device, it may simultaneously charge multiple new energy vehicles, so multiple charging packs 2 can be arranged on one charging guide rail 1, and each charging pack 2 can freely slide on the charging guide rail 1. A plurality of mounting frames 4 are arranged on the charging guide rail 1 in the direction of the charging guide rail 1, the charging guide rail 1 is disconnected at the position of each mounting frame 4 to form a gap, and a charging pack track switching mechanism is arranged at each gap. The charging pack track switching mechanism is connected with the mounting frame 4. When the charging pack 2 that cannot be used (faulty charging pack, charging pack without power, etc.) moves to the charging pack track switching mechanism, the charging pack track switching mechanism starts to work, moves the charging pack 2 and the track where the charging pack 2 is located out of the charging guide rail 1, connects the other tracks of the charging pack track switching mechanism with the charging guide rail 1, and the remaining charging packs 2 normally pass through.

[0062] The rail changing mechanism of the charging package includes a rail changing frame 3 fixedly connected to the bottom of the mounting frame 4. The rail changing frame 3 includes two groups of transverse rails 31 arranged in front and back along the direction of the charging rail 1, and the direction of the transverse rails 31 is perpendicular to the direction of the charging rail 1. Two groups of moving rails 32 are arranged in front and back along the direction of the transverse rails 31, and the direction of the moving rails 32 is perpendicular to the direction of the transverse rails 31. The inner side of each group of transverse rails 31 is provided with a groove 311, and each group of moving rails 32 is provided with two sliding wheels 34 arranged in front and back, which are clamped in the groove 311 and can move along the length direction of the groove 311. After the two groups of moving rails 32 are installed on the transverse rails 31, the two groups of moving rails 32 can move synchronously on the transverse rails 31. The rail changing mechanism 33 is fixedly connected to the transverse rails 31 or the mounting frame 4, which can push the moving rails 32 to move along the direction of the transverse rails 31, so as to switch different moving rails 32 to be in communication with the charging rail 1.

[0063] The rail changing mechanism 33 includes two screw rod seats 331 arranged in front and back along the length direction of the transverse rails 31, and the two screw rod seats 331 are fixedly connected to the transverse rails 31 or the mounting frame 4. A screw rod 332 is fixedly connected between the two screw rod seats 331, and the screw rod 332 cannot rotate on the screw rod seat 331. A connecting plate 333 and a second bevel gear 334 are sleeved on the screw rod 332. The connecting plate 333 is clearance-fitted with the screw rod 332, and the connecting plate 333 is connected with the moving rail 32. The connecting plate 333 is connected with the second bevel gear 334 through a bearing, and the connecting plate 333 is fixed and cannot rotate, while the second bevel gear 334 can rotate. The second bevel gear 334 is connected with the screw rod 332 through threads, and when an external force drives the second bevel gear 334 to rotate on the screw rod 332, the second bevel gear 334 rotates and moves along the axial direction of the screw rod 332.

[0064] When the external power drives the second bevel gear 334 to rotate, since the second bevel gear 334 is threadedly connected with the screw rod 332, and under the action of the connecting plate 333 and the moving rail 32 (which can only move along the axial direction of the screw rod 332 and cannot rotate), the second bevel gear 334 can only move along the axial direction of the screw rod 332 on the screw rod 332, and drives the moving rail 32 to move synchronously. During the movement of the moving rail 32, when the moving rail 32 moves to a specified position (a gap of the charging rail 1), the moving rail 32 can be in communication with the charging rail 1 (communication), and the charging package 2 can move to the specified position through the charging rail 1 and the moving rail 32 to charge the vehicle.

[0065] The foregoing external driving is a driving mechanism on the charging package 2. The charging package 2 is movably connected to the moving rail 32, and the charging package 2 is further provided with a driving mechanism for driving the first bevel gear 334 to rotate. The driving mechanism drives the second bevel gear 334 to rotate.

[0066] The embodiment also provides a specific structure of the charging package 2. That is, the charging package 2 comprises a package shell 21, the package shell 21 is hung on the moving guide rail 32 through a roller 23 on the package shell 21, and the charging package 2 can move on the moving guide rail 32 and the charging guide rail 1 through the roller 23. The driving mechanism comprises a transverse driving motor 216 arranged on the package shell 21, the transverse driving motor 216 can adopt a servo motor, and the rotation angle thereof can be accurately controlled. The driving mechanism also comprises a second bevel gear 211 arranged on the package shell 21, the second bevel gear 211 can freely rotate on the package shell 21 under the driving of the transverse driving motor 216. The second bevel gear 211 is vertically engaged with the first bevel gear 334. The vertical engagement has two functions, one is to realize transmission, and power is transmitted from the second bevel gear 211 to the first bevel gear 334; the other is to realize power steering, and the rotation around the y-axis is converted into the rotation around the x-axis.

[0067] In order to realize that the charging package 2 does not cause the transmission structure to collide when moving, and on the other hand, the moving guide rail 3 can be driven to move by the transmission structure. Therefore, the first gear 217 and the second gear 214 are further installed on the package shell 21, and the first gear 217 and the second gear 214 are coaxially connected and synchronously rotated. The output shaft of the transverse driving motor 216 is provided with a worm 215, and the worm 215 is coaxially rotated with the output shaft of the transverse driving motor 216. The worm 215 is connected with the first gear 217 through a first transmission mechanism on one side, and more specifically, the first transmission mechanism is a gear set, the worm 215 is meshed with the first gear of the first transmission mechanism, the gears in the first transmission mechanism are sequentially meshed, and the last gear of the first transmission mechanism is meshed with the first gear 217. In this way, the movement of the worm 215 can be transmitted to the first gear 217 through the first transmission mechanism, and the first gear 217 generates rotation. The second gear 214 can be directly meshed with the second bevel gear 211, or can be meshed with the second bevel gear 211 through a second transmission mechanism. The second gear 214 is meshed with the first gear of the second transmission mechanism, the gears in the second transmission mechanism are sequentially meshed, and the last gear of the second transmission mechanism is meshed with the second bevel gear 211. In this way, the movement of the second gear 214 can be transmitted to the second bevel gear 211 through the second transmission mechanism, and the second bevel gear 211 generates rotation. In addition, a notch 2141 is formed on the second gear 214, and the notch 2141 is arranged along the axial direction of the second gear 214. By forming the notch 2141 on the second gear 214, when the charging package 2 passes between the charging rail 1 and the rail changing mechanism 3, the notch 2141 on the second gear 214 is opposite to the gear on the rail changing mechanism 3. The charging package 2 can smoothly transition from the charging rail 1 to the moving guide rail 32 of the rail changing mechanism 3, and the notch 2141 on the second gear 214 can effectively avoid collision with the gear on the rail changing mechanism 3; when rail changing is needed, the second gear 214 is rotated, and the second gear and the gear on the rail changing mechanism are meshed, that is, the second gear and the gear on the rail changing mechanism are switched between "meshing - not meshing - meshing - not meshing - … - meshing - not meshing - meshing - not meshing", and the first bevel gear 334 of the rail changing mechanism 3 is driven to rotate by the second gear 214.

[0068] As a preferred, the second transmission mechanism includes a fourth gear 212 and a third gear 213, the second gear 214 is meshed with the third gear 213, the third gear 213 is meshed with the fourth gear 212, and the fourth gear 212 is coaxially rotated with the second bevel gear 211.

[0069] The mobile guide rail 32 is an I-shaped guide rail, and the bottom of the two sides of the I-shaped guide rail is a guide rail surface for the rollers 23 on the charging bag 2 to slide. The top of the bag body shell 21 is provided with a U-shaped connecting frame 22, the rollers 23 are installed inside the U-shaped connecting frame 22, and the bottoms of the rollers 23 on both sides are in contact with the tracks on both sides of the mobile guide rail 32, so that the bag body shell 21 is hung on the mobile guide rail 32 through the rollers 23, and the charging bag 2 can move on the mobile guide rail 32. Similarly, the charging guide rail 1 and the charging bag 2 are connected in the same way.

[0070] The transverse guide rail 31 is provided with at least two groups of mobile guide rails 32 along the length direction of the transverse guide rail 31, and the two groups of mobile guide rails 32 are linked and moved together along the length direction of the transverse guide rail 31. When the charging bag 2 is abnormal (has a charging task, is damaged, or is out of power, etc.), the charging bag 2 moves to the mobile guide rail 32 at a certain gap, and then the first bevel gear 334 is finally driven to rotate by the transverse drive motor 216, the first bevel gear 334 rotates while moving on the lead screw 332 along the axial direction of the lead screw 332, and the plurality of groups of mobile guide rails 32 are synchronously moved, so that the other group of mobile guide rails 32 is moved to be aligned with the charging guide rail 1, the charging bag 2 is transitioned from one charging guide rail 1 to the other charging guide rail 1 through the mobile guide rail 32, and the smooth sliding of the charging bag 2 is realized, so that the charging bag can be moved to any specified position of the charging guide rail 1.
