Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging technology, and in particular to a DC split-type charging host. Background Technology

[0002] With social progress and technological development, green and environmentally friendly sustainable development is our development philosophy. The use of new energy vehicles can effectively reduce gasoline consumption and usage, reduce carbon dioxide emissions, and make a significant contribution to protecting air cleanliness. Therefore, new energy vehicles have been widely promoted and loved since their introduction.

[0003] New energy vehicles need to recharge at designated charging stations, but existing charging units still have the following problems: Existing charging hosts are divided into two types: integrated charging hosts and separate charging hosts. Among them, the separate charging host adopts a one-machine-multiple-terminal mode. However, the existing separate charging hosts are more troublesome to transport and need to be moved multiple times. In addition, the charging terminals exist independently and are easily damaged when working in some poor environmental conditions, which affects their service life.

[0004] To address the above problems, this invention proposes a DC split-type charging host. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of transporting separate main units and insufficient protection for charging terminals, and to propose a DC separate charging main unit.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A DC split-type charging host includes: The installation box has a base fixedly installed at the bottom, two movable doors hinged to one side of the installation box for easy maintenance by the user, and a storage compartment fixedly installed on the top of the installation box. The first charging terminal and the second charging terminal are respectively disposed on both sides of the mounting box. The first charging terminal and the second charging terminal can be used to connect with the vehicle to be charged. The ejection component is used to eject the first and second charging terminals on both sides to facilitate connection with surrounding vehicles waiting to be charged; A shielding component that can move synchronously when the first charging terminal and the second charging terminal move, and that can provide shielding above the first charging terminal and the second charging terminal.

[0007] In one possible design, the ejection assembly includes a motor fixedly mounted on the inner wall of one side of the mounting box. A first bevel gear is fixedly mounted on one end of the motor's output shaft via a rotating shaft. The first bevel gear meshes with a second bevel gear. A gear disk is fixedly mounted on the bottom of the second bevel gear and is rotatably connected to the bottom inner wall of the mounting box. A first sliding bracket and a second sliding bracket are respectively provided on both sides of the mounting box. Each of the first and second sliding brackets consists of a support plate and two connecting rods. The first and second sliding brackets are located on the same plane. The two connecting rods of the first and second sliding brackets are staggered, closely abutting each other, and slidingly pass through both sides of the mounting box. Multiple locking teeth are provided on the side of the first and second sliding brackets closest to the connecting rods of the gear disk. The gear disk meshes with the first and second sliding brackets via these multiple locking teeth. A first charging terminal is fixedly mounted to the top of the support plate of the first sliding bracket by bolts, and a second charging terminal is fixedly mounted to the top of the support plate of the second sliding bracket by bolts.

[0008] In one possible design, the shielding assembly includes a first L-shaped connecting rod (33) fixedly installed on one side of a first sliding bracket and a second L-shaped connecting rod (34) fixedly installed on one side of a second sliding bracket (10). A first sliding plate is fixedly installed on the top of the first L-shaped connecting rod, and a second sliding plate is fixedly installed on the top of the second L-shaped connecting rod. Both the first and second sliding plates are slidably connected to one side of the storage compartment. Fixed plates are fixedly installed at the ends of the first and second sliding plates that are far apart from each other. A first tarpaulin and a second tarpaulin are fixedly installed on one side of each of the two fixed plates, respectively. One end of the first tarpaulin and the second tarpaulin slide through both sides of the storage compartment. A first winding shaft and a second winding shaft are rotatably installed between the inner walls of both sides of the storage compartment. One end of the first tarpaulin is fixedly connected to the outer wall of the first winding shaft and the first tarpaulin is wound onto the first winding shaft. One end of the second tarpaulin is fixedly connected to the outer wall of the second winding shaft and the second tarpaulin is wound onto the second winding shaft. A torsion spring is sleeved on the outer wall of both the first winding shaft and the second winding shaft. One end of each torsion spring is fixedly connected to the outer wall of the first winding shaft and the second winding shaft, respectively. The other end of each torsion spring is fixedly connected to one inner wall of the storage compartment.

[0009] In one possible design, a third bevel gear and a fourth bevel gear mesh on both sides of the first and second bevel gears, respectively. A first rotating shaft is fixedly installed on one side of the third bevel gear, and a second rotating shaft is fixedly installed on one side of the fourth bevel gear. A sixth bevel gear is fixedly installed on the other end of both the first and second rotating shafts. Both sixth bevel gears mesh with fifth bevel gears. Two fixed brackets are fixedly installed on the bottom inner wall of the mounting box. A winding wheel is rotatably connected inside each of the two fixed brackets. The outer walls of the two winding wheels are fixedly connected to the two fifth bevel gears, respectively. Connecting wires are wound on the outer walls of the two winding wheels. The other ends of the two connecting wires slide through both sides of the mounting box and are connected to the first charging terminal and the second charging terminal, respectively.

[0010] In one possible design, the interior of the mounting box is divided into two parts: a mounting cavity and a heat dissipation cavity. The heat dissipation cavity is located at the top of the mounting cavity and is connected to the mounting cavity through holes. Multiple heat dissipation holes are provided on both outer walls of the heat dissipation cavity.

[0011] In one possible design, an L-shaped partition is fixedly installed on the bottom inner wall of the mounting box, and the L-shaped partition is located above the ejection assembly.

[0012] In one possible design, multiple through holes are provided on the support plates of both the first and second sliding brackets.

[0013] In one possible design, the shorter end of the second L-shaped connecting rod is longer than the shorter end of the first L-shaped connecting rod, which can meet the need for fixed connection with the second sliding bracket and the first sliding bracket.

[0014] In this application, during use, the user can start the motor, which drives the gear disk to rotate via the first and second bevel gears. The gear disk simultaneously engages with the first and second sliding brackets, completing the simultaneous ejection of the first and second charging terminals on both sides. At the same time, the first and second bevel gears also engage with the third and fourth bevel gears during rotation, driving the take-up wheels on both sides to rotate via the transmission of the first and fourth bevel gears. This facilitates the output of the corresponding connecting cables in coordination with the movement of the first and second charging terminals, preventing obstruction of the movement of the first and second charging terminals. Simultaneously, it also allows for the output of the corresponding connecting cables from the first and second charging terminals. When the terminal is retracted, it facilitates the winding of the connecting cable. When the first and second charging terminals are extended, the first and second tarpaulins on top of the first and second charging terminals move synchronously with the movement of the first and second sliding brackets. With the connection of the first and second L-shaped connecting rods, the movement of the first and second tarpaulins is well-controlled and highly synchronized, ensuring that the first and second charging terminals are stably and continuously shielded, facilitating use in various environments. The torsion springs also keep the first and second tarpaulins taut at all times, and facilitate easy winding of both during retraction, making them convenient to use.

[0015] In this invention, a DC split-type charging host can install the charging terminal on both sides of the charging host through the push-out component, which can facilitate transportation. In the installed state, the charging terminal can be extended without affecting the use of the charging state. When needed, the charging terminal can also be removed for normal split-type use, making it more flexible in use. In this invention, the DC split-type charging host, through the shielding component, can continuously shield the charging terminal when it is installed on both sides of the charging host, which can reduce the damage of the external environment to the charging terminal. At the same time, the tarpaulin used for shielding can extend synchronously with the extension of the terminal, so the shielding effect is good and it is beneficial for the long-term use of the charging terminal. In this invention, the split-type charging host can be combined with up to two charging terminals for easy transportation. The charging terminals can be extended while installed without affecting charging. When needed, the charging terminals can be detached for normal split-type use, offering great flexibility. Furthermore, when the charging terminals are installed on both sides of the charging host, they can be continuously shielded, reducing damage from the external environment. The tarpaulin used for shielding extends synchronously with the terminals, providing effective shielding and promoting long-term use. Attached Figure Description

The first sliding bracket 9 and the second sliding bracket 10 are each composed of a support plate and two connecting rods. The first sliding bracket 9 and the second sliding bracket 10 are located on the same plane. The two connecting rods of the first sliding bracket 9 and the second sliding bracket 10 are staggered and closely attached and slide through both sides of the mounting box 1.

The push-out component is used to push out the first charging terminal 5 and the second charging terminal 6 on both sides, so that they extend to both sides, ensuring that there is a large space around the first charging terminal 5 and the second charging terminal 6, which can be easily connected to the surrounding vehicles waiting to be charged and is convenient to use. The shielding assembly includes a first L-shaped connecting rod 33 fixedly installed on one side of the first sliding bracket 9 and a second L-shaped connecting rod 34 fixedly installed on one side of the second sliding bracket 10.

[0020] Example 2 Improvements based on Example 1: Reference Figure 4 In this embodiment, a third bevel gear 16 and a fourth bevel gear 18 are respectively meshed on both sides of the first bevel gear 12 and the second bevel gear 13. A first rotating shaft 17 is fixedly installed on one side of the third bevel gear 16, and a second rotating shaft 19 is fixedly installed on one side of the fourth bevel gear 18. A sixth bevel gear 23 is fixedly installed on the other end of both the first rotating shaft 17 and the second rotating shaft 19. Both sixth bevel gears 23 mesh with fifth bevel gears 22. Two fixed brackets 20 are fixedly installed on the bottom inner wall of the mounting box 1. Both fixed brackets 20 rotate within their respective inner walls. The device is equipped with two take-up wheels 21. The outer walls of the two take-up wheels 21 are fixedly connected to two fifth bevel gears 22, respectively. The outer walls of the two take-up wheels 21 are wound with connecting wires 24. The other ends of the two connecting wires 24 slide through both sides of the mounting box 1 and are connected to the first charging terminal 5 and the second charging terminal 6, respectively. By providing two take-up wheels 21, the two charging terminals can be moved easily, avoiding the connection wires 24 from restricting movement. At the same time, the take-up wheels 21 can rotate synchronously as the charging terminals extend, resulting in better performance.

[0021] Reference Figure 2 In this embodiment, the interior of the mounting box 1 is divided into two parts: the mounting cavity and the heat dissipation cavity. The heat dissipation cavity is located at the top of the mounting cavity and is connected to the mounting cavity through holes. Multiple heat dissipation holes 8 are provided on both outer walls of the heat dissipation cavity, which can facilitate better heat dissipation of the charging host during use.

[0022] Reference Figure 2 , 3 In this embodiment, an L-shaped partition 7 is fixedly installed on the bottom inner wall of the mounting box 1. The L-shaped partition 7 is located above the ejection assembly and can cover multiple mounting structures at the bottom of the mounting box 1. It can also facilitate the subsequent installation of the charging host body inside the mounting box.

[0023] Reference Figure 6 In this embodiment, multiple through holes 35 are provided on the support plates of the first sliding bracket 9 and the second sliding bracket 10, which can prevent water from accumulating on the top of the support plate during use, and also facilitate the fixing of the charging terminal.

[0024] Reference Figure 4 , 6 In this embodiment, the shorter end of the second L-shaped connecting rod 34 is longer than the shorter end of the first L-shaped connecting rod 33, which can meet the need for fixed connection with the second sliding bracket 10 and the first sliding bracket 9. Since the first sliding bracket 9 and the second sliding bracket 10 are installed alternately, the above design can ensure that the two L-shaped connecting rods can be better connected with the corresponding sliding brackets.

[0025] However, as is well known to those skilled in the art, the working principle and wiring method of motor 11 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0026] The working principle and usage process of this technical solution are as follows: During use, the user can start the motor 11. The motor 11 will drive the gear disk 14 to rotate through the first bevel gear 12 and the second bevel gear 13. The gear disk 14 will simultaneously mesh with the first sliding bracket 9 and the second sliding bracket 10, completing the simultaneous ejection of the first charging terminal 5 and the second charging terminal 6 on both sides. At the same time, the first bevel gear 12 and the second bevel gear 13 will also mesh with the third bevel gear 16 and the fourth bevel gear 18 while rotating. Through the transmission of the first rotating shaft 17 and the second rotating shaft 19, the winding wheels 21 on both sides will also rotate, facilitating the output of the corresponding connecting wires 24 in coordination with the movement of the first charging terminal 5 and the second charging terminal 6, avoiding obstruction of the movement of the first charging terminal 5 and the second charging terminal 6. Simultaneously, it also facilitates the winding of the connecting wires 24 when the first charging terminal 5 and the second charging terminal 6 are retracted. When terminal 5 and the second charging terminal 6 are extended, the first sliding bracket 9 and the second sliding bracket 10 move, and the first tarpaulin 27 and the second tarpaulin 28 on the top of the first charging terminal 5 and the second charging terminal 6 also move synchronously. With the connection of the first L-shaped connecting rod 33 and the second L-shaped connecting rod 34, the movement of the first tarpaulin 27 and the second tarpaulin 28 can be well ensured and the synchronization rate is high. This ensures that the first charging terminal 5 and the second charging terminal 6 can be stably and continuously shielded, making it convenient to use in various environments. The torsion spring 29 can also keep the first tarpaulin 27 and the second tarpaulin 28 taut at all times, and at the same time, it can be easily rolled up when retracted, making it convenient to use. By making the charging terminal detachable and installable on the charging host, it is convenient for users to transport it. At the same time, it can shield and protect the charging terminal when used in a poor environment. It can be detached and separated when needed, making it flexible to use.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
