Description

Technical Field

[0001] The present invention discloses a combined system and method for a charger towing cart, and belongs to the field of vehicle charging. Background Art

[0002] New energy electric vehicles refer to vehicles that use unconventional vehicle fuels as the power source (or use conventional vehicle fuels and adopt new in-vehicle power devices), and integrate advanced technologies in the power control and drive aspects of the vehicle to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] With the popularization of new energy electric vehicles, there are more and more charging parking spaces, but they still cannot meet the charging needs of all vehicles. Especially when some gasoline vehicles park in the charging parking spaces, the utilization rate of the charging parking spaces decreases, resulting in a more scarce supply of charging parking spaces. Therefore, some cities have issued regulations prohibiting fuel vehicles from parking in charging parking spaces, but there are still problems of mixed parking in some cities that have not issued such regulations.

[0004] Currently, charging parking spaces generally have one charging pile for one parking space, and the charging piles are fixed. Especially for a parking lot with both new energy electric vehicle parking spaces and fuel vehicle parking spaces, new energy electric vehicles can only be charged when parked in the designated positions, which is very restrictive. In addition, when a fuel vehicle parks in a charging parking space, there is one less charging parking space, and the charging pile cannot be utilized. This not only fails to guarantee the charging of new energy electric vehicles but also leads to a waste of resources. Based on this, a combined system of a charger towing cart is needed to solve the above problems. Summary of the Invention

[0005] In view of the above, the present invention provides a combined system and method for a charger towing cart, which can solve the problems mentioned in the background art.

[0016] Furthermore, the charger support plate includes a first square steel layer and a second square steel layer. The first square steel layer and the second square steel layer are arranged perpendicular to each other. Both the first square steel layer and the second square steel layer are formed by laying a plurality of square steel bars flat. Insertion positions are formed between adjacent square steel bars in the first square steel layer and the second square steel layer. The insertion positions are used in corresponding matching with the pin plate. A plurality of angle irons are provided on the first square steel layer. The corners of the charger are defined within the angle irons.

[0036] The following specific embodiments will further illustrate the present disclosure in conjunction with the above-mentioned drawings. Specific embodiments

[0037] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the present disclosure will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other. In the following description, many specific details are set forth in order to fully understand the present disclosure. The described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present disclosure belongs. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0039] In each embodiment, for the convenience of description rather than limiting the present disclosure, the term "connection" used in the specification and claims of the present patent application for the present disclosure is not limited to physical or mechanical connection, but may include electrical connection, whether direct or indirect. "Upper", "lower", "below", "left", "right", etc. are only used to represent relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0040] Such as Figure 1As shown in the figure, it is a schematic structural diagram of a new energy electric vehicle in a charging state in a parking lot provided by an embodiment of the present disclosure. There are several parking spaces in the parking lot 3, which can be used for parking new energy electric vehicles and fuel vehicles. After the new energy electric vehicle parks in the parking space, the charger towing trolley 2 will carry the charger assembly 1 to the corresponding new energy electric vehicle 4, and then insert the charging plug 104 and the charging gun 103 into the socket of the parking lot 3 and the charging socket of the new energy electric vehicle 4 respectively through the robotic arm 203 on the charger towing trolley 2, and then charging can start. Through the setting of the charger towing trolley structure of the present application, when a new energy electric vehicle 4 enters and needs to be charged, the charger towing trolley 2 will carry the charger assembly 1 to the corresponding new energy electric vehicle 4 for charging, ensuring the full utilization of the charger assembly 1, and there is no phenomenon that the charging pile is installed in advance in the parking space in the traditional parking lot but finally not utilized, thus avoiding waste of resources; nor is it necessary to separately demarcate a special parking area for new energy electric vehicles 4 and fuel electric vehicles, which is beneficial to improving the flexibility of parking new energy electric vehicles 4 and fuel electric vehicles, and also helps to improve the utilization rate of the entire parking lot 3.

[0041] As Figures 2 to 5 shown, a charger towing trolley combination system includes a charger assembly 1 and a charger towing trolley 2; the charger assembly 1 includes a charger pallet 101, and a charger 102 is arranged on the charger pallet 101. Figure 3 It can be seen that the charger pallet 101 includes a first square steel layer 1011 and a second square steel layer 1012. The first square steel layer 1011 and the second square steel layer 1012 are arranged perpendicular to each other, and both the first square steel layer 1011 and the second square steel layer 1012 are formed by laying a number of square steel bars flat, so that the formed charger pallet 101 has relatively good compressive strength and flatness, a durable structure, and good load-bearing effect.

[0042] A charging gun 103 and a charging plug 104 are connected to the charger 102. The charging gun 103 is matched with the charging socket of the new energy electric vehicle 4, and the charging plug 104 is matched with the socket of the parking lot 3.

[0043] The charger towing trolley 2 includes a vehicle body 201. The vehicle body 201 is provided with driving wheels 202 and a robotic arm 203. The vehicle body 201 includes a base 2011 and a frame 2012. Figure 2 It can be seen that the frame 2012 is fixedly connected to the base 2011, and the frame 2012 is also fixed by welding square steel, which is durable and strong. The robotic arm 203 is fixedly connected to the frame 2012 by bolts, and the driving wheels 202 are located below the base 2011; actually, the driving wheels 202 are located on the lower surface of the base 2011. Figure 2 、 Figure 4 and Figure 5Only a part of the powered wheels 202 is shown in perspective, and the movement of the powered wheels 202 drives the movement of the vehicle body 201.

[0044] A robotic arm clamp 204 is provided at the end of the robotic arm 203. The robotic arm clamp 204 is a prior art and has the functions of clamping and loosening. The robotic arm clamp 204 is used in correspondence and matching with the charging gun 103 and the charging plug 104, and can clamp, hold and loosen the charging gun 103 and the charging plug 104.

[0045] A carrying component is provided on the vehicle body 201. The carrying component is a lifting component or a dragging component. When the carrying component adopts the structure of the lifting component, it will lift and carry the charger component 1 to the new energy electric vehicle 4; when the carrying component adopts the structure of the dragging component, it will lift and drag the charger component 1 to the new energy electric vehicle 4; either of the above two structures is acceptable and is not limited herein. In this embodiment, the carrying component adopts the structure of the lifting component, and the lifting component is used in correspondence and matching with the charger support plate 101. The lifting component is inserted into the charger support plate 101 and lifted, so as to carry the charger component 1. Specifically, the carrying component includes a bracket 205, a lifting device 206 and a bracket 207. The bracket 205 is fixedly connected to the vehicle body 201 by welding or screwing. The lifting device 206 includes a linear pair guide rail, a driving motor, a lead screw and a nut. The linear pair guide rail is fixedly welded to the bracket 205, and the bracket 207 is slidably connected to the linear pair guide rail; the driving motor is located at the top of the bracket 205 and is fixedly connected to the bracket 205. The driving motor is connected to the lead screw, and the driving motor drives the rotation of the lead screw. The nut is connected to the lead screw in a matching manner, and the nut is fixedly connected to the bracket 207. Therefore, when the driving motor drives the lead screw to rotate forward or backward, according to the working principle of the lead screw and the nut, it will drive the bracket 207 to lift along the linear pair guide rail.

[0046] A split pin plate 2071 is formed in front of the bracket 207. Correspondingly, an insertion position is formed between adjacent square steel bars in the first square steel layer 1011 and the second square steel layer 1012. The insertion position is used in correspondence and matching with the pin plate 2071. Therefore, when it is necessary to carry the charger component 1, first lift the charger component 1. At this time, insert the pin plate 2071 into the insertion position formed between adjacent square steel bars, and then control the bracket 207 to rise through the lifting device 206.

[0047] From Figure 3It can be seen that several angle irons 208 are provided on the first square steel layer 1011. The angle irons 208 are fixed on the surface of the first square steel layer 1011 by welding machines or screws. The corners of the charger 102 are limited within the angle irons 208, that is, the angle irons 208 play a role in limiting the charger 102, which helps to maintain the stability of the charger 102 on the charger pallet 101.

[0048] When the charger transportation trolley 2 needs to carry the charger assembly 1, it moves forward and inserts the pin plate 2071 in the carrying assembly into the charger pallet 101. Therefore, when designing the structure of the charger transportation trolley 2, the carrying assembly is designed on one side of the vehicle body 201 in the forward direction, which helps the charger transportation trolley 2 to move and operate.

[0049] The charger assembly 1 is provided with a positioning transmitter, and the charger transportation trolley 2 is provided with a positioning receiver. The positioning transmitter and the positioning receiver are used in a matching manner; both the positioning transmitter and the positioning receiver are existing technologies. When a vehicle needs to be charged, the charger transportation trolley 2 receives the signal emitted by the positioning transmitter in the charger assembly 1 through the positioning receiver to find the position of the charger assembly 1. Then, the charger transportation trolley 2 carries and moves the charger assembly 1 to the new energy electric vehicle 4 that needs to be charged through the carrying assembly. Finally, the charging plug 104 and the charging gun 103 are clamped by the robotic arm fixture 204 on the robotic arm 203 of the charger transportation trolley 2 and inserted into the socket in the parking lot 3 and the charging socket of the new energy electric vehicle 4 respectively, and then the charging can start.

[0050] The present invention also provides a method for applying a charger transportation trolley combined system, which is applied to a charger transportation trolley combined system. The charger transportation trolley combined system includes a charger assembly 1 and a charger transportation trolley 2. The application method includes:

[0051] When a new energy electric vehicle needs to be charged, the charger transportation trolley 2 will search for the charger assembly 1, carry the charger assembly 1 to the new energy electric vehicle 4, and charge the new energy electric vehicle 4.

[0052] The charger assembly 1 includes a charger 102 and a positioning transmitter. A charging gun 103 and a charging plug 104 are connected to the charger 102; the motor transportation trolley 2 includes a vehicle body 201. A carrying assembly, a robotic arm 203, and a positioning transmitter are provided on the vehicle body 201. A robotic arm fixture 204 is provided at the end of the robotic arm 203. The robotic arm fixture 204 is used in corresponding matching with the charging gun 103 and the charging plug 104. The steps for the charger transportation trolley 2 to search for the charger assembly 2, carry the charger assembly 2 to the new energy electric vehicle 4, and charge the new energy electric vehicle 4 include the following:

[0053] (1) When a new energy electric vehicle 4 needs to be charged, the positioning transmitter in the charger assembly 1 will emit a signal. The charger towing cart 2 receives the signal emitted by the positioning transmitter through the positioning receiver and moves to the charger assembly 1;

[0054] (2) The charger towing cart 2 lifts or drags the charger assembly 1 through the carrying component and moves to the new energy electric vehicle 4 that needs to be charged;

[0055] (3) The gripper 204 on the robotic arm 203 of the charger towing cart 2 successively grips the charging plug 104 and the charging gun 103. After inserting the charging plug 104 into the socket in the parking lot and inserting the charging plug 104 into the charging socket of the new energy electric vehicle 4, charging can begin.

[0056] The above system and method can help improve the flexibility of parking new energy electric vehicles 4 and fuel vehicles, without being restricted by the specified area, improve the overall utilization efficiency of the parking lot, and also avoid the phenomenon that the charging piles are fixedly installed in a traditional parking lot but not utilized, reducing waste of resources.
