Description

Technical Field

[0001] This invention relates to the field of electric vehicle technology, and in particular to a child electric vehicle with a concealed battery charging port. Background Technology

[0002] Two-wheeled electric vehicles are a modern and common means of transportation. With the development of technology, electric technology has been applied to the field of children's vehicles. Currently, in order to make the charging port of two-wheeled electric vehicles waterproof and dustproof during operation, it is usually equipped with a flip cover on the outside.

[0003] CN207029323U discloses a hidden charging port structure for electric vehicles. The charging port can be opened with one hand before charging, and the cover can be automatically closed after the plug is unplugged after charging is completed.

[0004] However, applying this type of concealed charging port to children's electric vehicles presents the following drawbacks and shortcomings:

[0005] 1. Children have small hands and need to hold the plug with one hand and open the flip cover with the other to charge the vehicle, which is inconvenient. In addition, children tend to rush to charge the vehicle before it is fully upright, which can damage the plug and charging port if the vehicle is tilted over due to instability.

[0006] 2. In addition, children are often reckless and use electric vehicles without realizing that the vehicle is charging, causing excessive strain on the plug and charging port, which damages the aforementioned accessories. Summary of the Invention

[0007] This invention addresses the shortcomings of existing technologies by providing a child electric vehicle with a concealed battery charging port.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a child electric vehicle with a hidden battery charging port, comprising a vehicle body, a charging port, and a flip cover disposed on the vehicle body that cooperates with the charging port.

[0028] Figure 2 This is a partial enlarged structural diagram of point A in the present invention.

[0029] Figure 3 This is a diagram showing the state of the stand when the legs of the present invention are folded.

[0030] Figure 4 This is a diagram showing the state of the present invention when standing upright. Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-4 A child electric vehicle with a concealed charging port includes a vehicle body 1, a charging port 2, and a flip cover 3 mounted on the vehicle body 1 that mates with the charging port 2. Specifically, the flip cover 3 is rotatably mounted on the outer wall of the vehicle body 1, and the charging port 2 is slidably disposed through the wall of the vehicle body 1. The wall of the vehicle body 1 has guide holes that conform to the shape of the charging port 2. When the charging port 2 slides towards the flip cover 3, the flip cover 3 can be moved along... Figure 1 Rotate counterclockwise as shown to open the flip cover 3, revealing the charging port 2. The user can then directly insert the plug into the charging port 2 to charge the device.

[0032] To ensure that the charging port 2 is automatically exposed when the vehicle is standing, a limiting plate 502 is fixed on the side of the charging port 2 away from the flip cover 3. A first spring 105 is provided between the limiting plate 502 and the wall of the vehicle body 1. The first spring 105 is sleeved on the outer wall of the charging port 2 and its two ends abut against the limiting plate 502 and the inner wall of the vehicle body 1, respectively. Preferably, the vehicle body 1 is provided with a cavity space for the charging port 2 and the limiting plate 502 to move. This is a conventional setting and will not be described in detail here.

[0033] A pull rope 102 is provided on the limiting plate 502, and a second guide plate 104 is provided on the vehicle body 1 for the pull rope 102 to pass through. One end of the pull rope 102 is fixedly connected to the limiting plate 502, and the other end is passed through the guide plate 104. When the pull rope 102 pulls the limiting plate 502, the charging port 2 can slide towards the flip cover 3, opening the flip cover 3. At the same time, the limiting plate 502 compresses the first spring 105 to store force. When the pulling force of the pull rope 102 disappears, the charging port 2 is reset under the elastic force of the first spring 105.

[0034] The vehicle body 1 is also equipped with a stand 101, which is used for standing after the vehicle body 1 is parked. A tension spring is installed between the vehicle body 1 and the stand 101 so that the stand 101 is in a folded state when the vehicle is in motion, i.e. Figure 3 The state shown is the standard setup for a two-wheeled electric vehicle, and will not be described in detail here. The support 101 includes a support rod and a rotating plate 106. A rotating shaft 201 is provided on the vehicle body 1, and the support 101 is rotatably connected to the rotating shaft 201 through the rotating plate 106. When the support 101 moves along... Figure 3 After rotating clockwise as shown, it can form Figure 4 The standing position is shown, at which point the rotating plate 106 rotates clockwise along the rotating shaft 201 by an angle, preferably 70-130°.

[0035] The rotating plate 106 is provided with a drive plate 501 connected to the pull rope 102, such as Figure 3 As shown, the vehicle body 1 is provided with a first guide plate 103 for the pull rope 102 to pass through. That is, one end of the pull rope 102 is fixed to the limiting plate 502, and the other end passes through the second guide plate 104 and the first guide plate 103 in sequence and is fixedly connected to the drive plate 501. The pull rope 102 and the drive plate 501 can be riveted. When the stand 101 rotates, the drive plate 501 pulls the pull rope 102 under the rotation of the rotating plate 106, providing tension to the limiting plate 502, so that the charging port 2 slides to the side of the flip cover 3, so that the charging port 2 is exposed. That is, when the electric vehicle is parked, the stand 101 rotates and stands up, and the charging port 2 automatically pushes open the flip cover 3 through the pull rope 102. Then the user can directly insert the plug into the charging port 2 for charging.

[0036] To ensure that the stand 101 is locked during charging, the rotating plate 106 is provided with a locking groove 202, such as... Figure 3As shown, a locking pin 203 is slidably provided on the first guide plate 103 to cooperate with the rotating locking groove 202. The right end of the locking pin 203 is provided with an arc-shaped surface that can cooperate with the locking groove 202. The left end slides through the first guide plate 103 and is fixed with a magnetic suction plate 206. A first electromagnet 205 is fixed on the left end face of the first guide plate 103, which can attract the magnetic suction plate 206 when energized. A second spring 207 is provided between the magnetic suction plate 206 and the first guide plate 103. Specifically, the second spring 207 is sleeved on the locking pin 203 and its two ends abut against the first guide plate 103 and the magnetic suction plate 206 respectively. In use, the stand 101 is rotated clockwise to Figure 4 In the state shown, after the locking groove 202 rotates, it aligns with the position of the locking pin 203. Then, by energizing the first electromagnet 205, the magnetic plate 206 is attracted, causing the locking pin 203 to slide to the right and insert into the locking groove 202, thus locking the foot 101. Figure 4 The state shown is the state when the stand 101 is locked.

[0037] The bottom of the inner wall of the charging port 2 is provided with a first switch 204 that can trigger the first electromagnet 205 to be energized. That is, the first electromagnet 205 is electrically connected to the first switch 204. When the plug is inserted into the charging port 2, the plug abuts against the first switch 204, triggering the switch, thereby energizing the first electromagnet 205 to lock the locking groove 202, that is, to lock the stand 101. As can be seen from the above, when the electric vehicle is parked, the stand 101 rotates and stands up. At this time, the charging port 2 automatically opens the flip cover 3 to reveal itself. When charging is required, the plug is inserted into the charging port 2, triggering the first switch 204 to energize the first electromagnet 205. Then the stand 101 is locked by the locking pin 206, ensuring the stability of the vehicle in the charging state.

[0038] To prevent children from forcibly unlocking the stand 101 while it is charging, thus damaging the charging port 2 and plug, a sac 301 is provided on the side of the locking pin 203 near the rotating plate 106. Figure 3 As shown, the locking pin 203 passes through the bladder body 301. The right end of the bladder body 301 is fixed to the outer wall of the locking pin 203, and the left end is fixed to the first guide plate 103. The bladder body 301 is preferably a plastic folding bladder body, which is provided with an air inlet valve. This air inlet valve is a one-way valve, and its flow direction is from the outside into the inside of the bladder body 301. When the locking pin 203 slides towards the rotating plate 106, the bladder body 301 can be extended into a folding shape. Figure 4In the indicated state, gas flows into the bladder 301 through the inlet valve, causing the bladder 301 to expand. A cylinder 302, connected to the bladder 301 via a flexible hose, is located on the side of the limiting plate 502 away from the charging port 2. An outlet valve is provided between the bladder 301 and the cylinder 302, located on the flexible hose. This outlet valve is also a one-way valve, allowing gas to flow from the bladder 301 to the cylinder 302. A piston plate 303 slides within the cylinder 302, and the piston plate 303 is connected to the first switch 20 via a piston rod 304. 4. Fixed connection: The piston rod 304 is slidably installed through the wall at the bottom of the charging port 2. In use, when the stand 101 is forcibly rotated without the plug being pulled out, the locking groove 202 on the rotating plate 106 overcomes the attraction force of the first electromagnet 205 and pushes out the locking pin 203, which compresses the bladder 301. After the bladder 301 is compressed, gas is filled into the cylinder 302, causing the piston plate 303 to slide. This causes the piston rod 304 to push the plug out from inside the charging port 2, so that the plug is separated from the charging port 2, preventing dragging when the vehicle is forcibly driven.

[0039] As can be seen from the above embodiments, during normal use, the charging port 2 is exposed after the foot 101 is in a standing position. To prevent rainwater from entering the charging port 2 when parking in the wild, an extension component is provided based on this embodiment. A moisture sensing switch 401 is provided on the side of the flip cover 3 away from the charging port 2. The extension component includes a second electromagnet 402, a clutch plate 403, and a third spring 404. The second electromagnet 402 is electrically connected to the moisture sensing switch 401. The second electromagnet 402 is connected to the clutch plate 403 through the third spring 404. The pull rope 102 is fixed to the electromagnet 402 and the clutch plate 403 respectively. The third spring 404 is a tension spring. A third guide plate 405 is provided on the vehicle body 1 to cooperate with the pull rope 102. The extension component is set between the third guide plate 405 and the third guide plate 404. Between the guide plate 103; initially, the second electromagnet 402 is energized and firmly attracted to the clutch plate 403. After the foot 101 stands up, the pull rope 102 is pulled to push out the charging port 2. At this time, the pull rope 102 is in a taut state, and the clutch plate 403 and the second electromagnet 402 are also in a state of overall attraction. When the moisture sensor switch 401 senses moisture on the flip cover 3, it triggers the second electromagnet 402 to be de-energized. At this time, the clutch plate 403 is disengaged. The distance between the clutch plate 403 and the second electromagnet 402 is extended by the stretching of the third spring 404. Under the elastic force of the first spring 105, the extended distance of the charging port 2 is pulled, thereby resetting the charging port 2 and keeping it hidden inside the vehicle body 1, thus preventing rainwater from entering the charging port 2 and achieving protection when parking in the rain.

[0040] Using the above-mentioned method for a child electric vehicle with a hidden battery charging port: When the vehicle is stopped, step on the footrest 101 to make it rotate around the pivot 201 via the rotating plate 106, thereby making the vehicle stand up. At this time, the rotating plate 106 pulls the pull rope 102 through the drive plate 501, which pushes the charging port 2 open from the inside and opens the flip cover 3, thus realizing the automatic pop-out of the charging port.

[0041] Then the plug is inserted into the charging port 2, the first switch 204 is triggered, the first electromagnet 205 is energized and attracts the magnetic plate 206, the locking pin 203 slides under the drive of the magnetic plate 206 and cooperates with the locking groove 202, so that the stand 101 is locked, that is, when charging, the stand 101 is locked and cannot move.

[0042] When the footrest 101 is forcibly kicked away during charging, the locking groove 202 on the rotating plate 106 overcomes the attraction force of the first electromagnet 205 and pushes out the locking pin 203, which compresses the bladder 301. After the bladder 301 is compressed, gas is injected into the cylinder 302, causing the piston plate 303 to slide. This causes the piston rod 304 to push the plug out from inside the charging port 2, so that the plug is separated from the charging port 2, preventing dragging when the vehicle is forcibly driven.

[0043] Furthermore, when the electric vehicle is parked in the wild without being charged, the moisture sensor switch 401 on the flip cover 3 is triggered after rain, causing the second electromagnet 402 to be de-energized. At this time, the clutch plate 403 disengages from the magnet, and the distance between the clutch plate 403 and the second electromagnet 402 is extended by the stretching of the third spring 404. Under the elastic force of the first spring 105, the extended distance of the charging port 2 is pulled, thereby resetting the charging port 2 and keeping it hidden inside the vehicle body 1, thus preventing rainwater from entering the charging port 2 and achieving protection when parking in the rain.
