Description

Technical Field

[0001] The invention relates to the field of electric vehicle charging, in particular to a sliding contact charging structure for electric vehicles. Background Art

[0002] With the rapid development of my country's economy, transportation has also improved greatly. As a new type of transportation newly developed in recent years, electric vehicles have many advantages that other transportation vehicles do not have, such as lightness, environmental protection, and economy. Therefore, in the case of urban traffic congestion, electric vehicles are the transportation of choice for more and more office workers. When charging electric vehicles, they are generally charged at charging piles in designated locations to ensure charging safety.

[0003] At present, existing electric bicycles are all charged by wired means. This wired charging method has safety hazards such as wire aging, leakage caused by socket plugging and unplugging, and contact sparks. Although patent document CN110014890A discloses an electric bicycle wireless charging system, which avoids the safety hazards of traditional wired charging methods and improves charging safety, it does not take into account the influence of factors such as the tilt of the electric bicycle and the charging distance on the charging efficiency. In addition, the charging distance of the wireless charging device in the prior art is fixed and cannot flexibly adapt to the wireless charging of electric bicycles of different models. When there is a large offset between the transmitting end and the receiving end, the charging efficiency will be significantly reduced. Summary of the invention

[0004] The present invention aims to solve the above technical problems and provides a sliding contact charging structure for electric vehicles.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a sliding contact charging structure for an electric vehicle comprises a sub-plug mechanism, a female plug mechanism and an installation mechanism, wherein the sub-plug mechanism is arranged at the front side of the electric vehicle and comprises a fixing mechanism and a sub-contact sheet;

[0006] The female plug mechanism includes a mounting groove and a female contact piece, and the sub-contact piece and the female contact piece cooperate with each other;

[0007] The installation mechanism comprises a fixed vertical plate and a sliding block, and one side of the sliding block is connected to the installation groove through a spring structure.

[0008] Furthermore, the fixing mechanism includes a fixing block with cylinders on both sides of the fixing block. The sub-contact piece is designed as a V-shaped structure and is fixed on one side of the cylinder, so that the sub-contact piece and the mother contact piece can be effectively prevented from shifting during charging.

[0009] Furthermore, the fixed block is installed on the front side of the electric vehicle through a spring structure, and the spring structure includes a C-shaped plate, a spring is arranged in the C-shaped plate, and the spring is connected to the movable plate. One end of the movable plate is rotatably connected to the C-shaped plate, and the other end is fixedly connected to the fixed block. This spring structure can ensure that the entire sub-plug mechanism can rotate slightly left and right, limit shaking up and down, and prevent the position of the sub-plug mechanism and the mother plug mechanism from being offset.

[0010] Furthermore, the fixed block is a rectangular block structure, and elastic baffles are rotatably provided on the upper and lower sides, the two elastic baffles are symmetrically arranged, and the elastic baffles are arranged in an arc shape. When not charging, the elastic baffles can be used to protect the sub-contact sheet to prevent water or dust from affecting the accuracy of use;

[0011] Furthermore, the mounting groove and the female contact piece are both V-shaped structures that match the female contact piece, the female contact piece is fixed on the inner side of the mounting groove, and a female plug-in piece is provided at one end of the mounting groove away from the female contact piece, and the mounting groove can be used to protect the female contact piece;

[0012] Furthermore, the female blocking piece is rotatably connected to the mounting groove, and the female blocking piece is designed as an arc-shaped structure. When making contact, the female blocking piece can push up the elastic blocking piece. Due to the resistance, the female blocking piece itself will also rotate, so that the sub-contact piece and the female contact piece can be fully exposed.

[0013] Furthermore, when the two female blocking pieces are in a vertical state, the elastic blocking piece is located above the female blocking piece, so that when the sub-contact piece approaches, the female blocking piece can lift up the elastic blocking piece to fully expose the sub-contact piece and complete the contact with the female contact piece.

[0014] Furthermore, the fixed vertical plate is provided with a slide groove matched with the slider, and the slide groove is provided with a plurality of limiting holes. By adjusting the position of the slider and installing cylinders in the limiting holes to limit the slider, it is suitable for sub-plugs of different heights.

[0015] Furthermore, a wrapping strip is provided on a side of the installation slot away from the spring structure, and the wrapping strip is made of a flexible rubber material.

[0016] The advantages of the present invention compared with the prior art are:

[0017] 1. Design a spring in the fixing mechanism so that the sub-contact piece and the mother contact piece can swing back and forth when they come into contact, thus reducing the impact of the electric vehicle on the installation slot;

[0018] 2. Design a fixed vertical plate in the fixing mechanism, and the height of the entire structure can be adjusted through the limit holes to meet the needs of different heights;

[0019] 3. Both the sub-contact and the mother contact are designed to be powered, and the sub-contact is designed with positive and negative poles for attracting and fixing each other. In this way, the sub-contact and the mother contact are in sliding contact, which makes charging simple and convenient, improves safety and saves time.

[0020] Changing the traditional charging method, a separate charger is no longer needed, and charging is done by sliding contact, which is simple and convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Working principle of the present invention: The sliding contact charging structure for electric vehicles includes a sub-plug mechanism 1, a female plug mechanism 2 and a mounting mechanism 3. The sub-plug mechanism 1 is arranged on one side of the electric vehicle, including a fixing mechanism 4 and a sub-contact sheet 101. Fig.10 , Fig.11 As shown, cylinders 402 are provided on both sides of the fixing block 401, and the sub-contact piece is designed with a V-shaped structure. The sub-contact piece can be a copper contact and is fixed on two cylinders, wherein one sub-contact piece 101 is a positive electrode and the other sub-contact piece 101 is a negative electrode;

[0036] The female plug mechanism 2 includes a mounting groove 201 and a female contact sheet 202. The sub-contact sheet 101 and the female contact sheet 202 cooperate with each other, so one end of the female contact sheet is designed as a negative electrode and the other end is designed as a positive electrode. In this way, when the sub-contact sheet is in contact, they can attract each other, and can be energized for charging, and it is ensured that there is no displacement during charging, and the charging is stable;

[0037] like Figure 4 Figure 5As shown, the fixed block 401 is installed on the front side of the electric vehicle through the spring structure 5, and the spring structure 5 includes a C-shaped plate 501, and a spring 502 is arranged inside the C-shaped plate 501, and the spring 502 is connected to the movable plate 503, and one end of the movable plate 503 is rotatably connected to the C-shaped plate 501, and the other end is fixedly connected to the fixed block 401, so that when the sub-plug mechanism moves forward, when the elastic blocking piece and the mother plug blocking piece are squeezed, it is ensured that the entire sub-plug mechanism can be slightly shaken left and right with the mother plug mechanism, and will not shake up and down, in order to better ensure the contact between the sub-contact piece and the mother contact piece;

[0038] The mounting mechanism 3 includes a fixed vertical plate 301 and a slider 302. The fixed vertical plate 301 is provided with a slide groove 304 matched with the slider 302. The slide groove 304 is provided with a plurality of limiting holes 305. The height of the entire structure can be adjusted by moving the slider up and down. It is suitable for different electric vehicles. The slider can be fixed by installing objects such as cylinders in the limiting holes.

[0039] One side of the slider 302 is connected to the mounting groove 201 via a spring structure 5. The connection method of the spring structure is the same as that of the sub-plug mechanism. When the sub-plug mechanism is close to the mother plug mechanism, it is squeezed with the mother plug mechanism. In this way, the sub-plug mechanism can swing back and forth with the mother plug mechanism without moving up and down, and the impact on the entire charging device is reduced.

[0040] like Fig.10 , Fig.11 As shown, the fixed block 401 is a rectangular block structure, and elastic baffles 405 are rotatably arranged on the upper and lower sides, and the two elastic baffles 405 are symmetrically arranged. Figure 5 As shown, the elastic baffle 405 is arranged in an arc shape, so that when it is installed on the electric vehicle, the two elastic baffles can protect the sub-contact piece to prevent water or dust from affecting the accuracy of use;

[0041] The mounting groove 201 and the mother contact piece 202 are both V-shaped structures that match the child contact piece 101. The mother contact piece 202 is fixed on the inner side of the mounting groove 201. The mounting groove can protect the mother contact piece, and if charging is performed on a rainy day, the mother contact piece and the child contact piece will not be completely exposed to prevent accidents.

[0042] like Figure 4 Figure 5As shown, a female plug-in blocking piece 203 is provided at one end of the mounting groove 201 away from the female contact piece 202. The female plug-in blocking piece 203 is rotatably connected to the mounting groove 201, and the female plug-in blocking piece 203 is designed to be an arc-shaped structure. When the two female plug-in blocking pieces 203 are in a vertical state, the elastic blocking piece 405 is located above the female plug-in blocking piece 203. When the sub-plug mechanism is close to the female plug mechanism, the elastic blocking piece 405 is located above the female plug-in blocking piece 203. In this way, the female plug-in blocking piece can lift up the elastic blocking piece, so that the sub-contact piece and the female contact piece are fully exposed, and the female plug-in blocking piece can also be rotated to prevent breakage.

[0043] A wrapping strip 6 is provided on one side of the mounting groove 201 away from the spring structure 5. The wrapping strip 6 is made of a flexible rubber material. Figure 7 As shown, the cross-section of the entire wrapping strip presents a V-shaped structure, so that when charging is completed, the electric vehicle can be pushed forward directly. Due to the design of the spring structure, the entire female plug mechanism can be bent, and the wrapping strip can prevent the female plug mechanism from scratching the electric vehicle, and there is no need to return the electric vehicle.

[0044] Specific implementation method: Now fix the fixed vertical plate on the wall, and fix it by welding or screws. Adjust the height of the slider as needed, and use screws, cylinders and other items to cooperate with the limit holes to fix the height of the slider. Use a spring mechanism to install the sub-plug mechanism to the front side of the electric vehicle, and the power cord energizes the sub-contact piece and the mother contact piece through the wiring hole. When charging, the sub-plug mechanism is close to the mother plug mechanism, and the ends of the elastic baffle pieces are respectively located above the mother plug baffle pieces. When the sub-plug mechanism continues to move forward, the mother plug baffle piece will lift the elastic baffle piece, and the sub-contact piece and the mother contact piece will be fully exposed. Both the sub-contact piece and the mother contact piece are designed with positive and negative poles, so that sliding charging is more stable and no displacement occurs. When charging is completed, the sub-contact piece and the mother contact piece are separated, and the elastic baffle piece and the mother plug baffle piece are reset.

[0045] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
