Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging sockets, in particular to an electric tricycle charging hole with a waterproof function. Background Art

[0002] After searching, the Chinese patent "A safe charging socket for electric tricycles" has the authorization announcement number "CN212046992 U". This patented technology uses a control circuit to cut off the power of the entire vehicle during charging, and the entire vehicle cannot be driven during charging, avoiding forgetting to unplug the charger when using the vehicle and other misoperations; an RC oscillator for timing is provided in the single-chip microcomputer, which can monitor the charging time and automatically cut off the charging power supply when the charging time is exceeded to avoid overcharging and damaging the battery; over-temperature monitoring is achieved through a temperature sensor, and the power supply is automatically cut off and an alarm is issued when the temperature is too high to avoid spontaneous combustion; it avoids excessive charging time of electric vehicles, plug-in riding, and spontaneous combustion, thereby increasing charging safety.

[0003] Although the patented technology solves the problem that electric vehicle batteries need to be charged frequently and the charging time is 8-9 hours, users have no time to consider the charging time, which leads to overcharging, battery heating and aging, and reduced battery life. Second, most charging sockets are on the rear side of the vehicle, and when using, people often forget to unplug the charger and drive the electric vehicle directly, which can easily cause the charger to be damaged by dragging or even cause electric shock. Third, after long-term use, poor contact of the socket can easily cause the socket contacts to heat up, which can easily cause the vehicle to spontaneously combust. However, the waterproof groove and sealing strip of the patented technology cannot protect the charging needle of the charging port, and the charging needle will rust when it comes into contact with water vapor, resulting in poor contact between the charging needle and the plug, which may cause the charger to heat up and catch fire. Therefore, a waterproof charging port for electric tricycles is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide an electric tricycle charging port with a waterproof function in order to solve the above-mentioned problem, thereby improving the problem that the charging needle will rust when it comes into contact with water vapor, resulting in poor contact between the charging needle and the plug, which may cause the charger to heat up and catch fire.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a charging hole of an electric tricycle with a waterproof function, comprising a charging port; a protective component, wherein the protective component comprises a protective cover located in the charging port, a sensing plate is fixedly connected to one side of the protective cover, two photoelectric sensors are arranged in the charging port and are axially symmetrically distributed relative to the axis of the sensing plate, and an alarm light is arranged on the outside of the charging port.

[0006] Preferably, a charging needle is provided in the charging port, and the protective cover is connected to the charging needle, which can protect the charging needle to prevent the charging needle from rusting due to contact with water vapor.

[0007] Preferably, two fixing seats are fixedly connected to the outer side of the charging port and are axially symmetrically distributed relative to the axis of the charging port. A fixing hole is opened in the fixing seat. By installing a bolt into the fixing hole, the charging port can be installed in the electric vehicle.

[0008] Preferably, the length of the sensing plate is slightly smaller than the length between the two photoelectric sensors, which makes it easier for the photoelectric sensor to sense the position of the sensing plate in a timely manner to prevent the photoelectric sensor from not being able to sense the position due to the sensing plate being too short. At the same time, the photoelectric sensor will stop working during charging to prevent misjudgment.

[0009] Preferably, a buzzer is provided in the warning light, which is convenient for reminding the user to prevent the user from ignoring the light of the warning light during the day, which is safer.

[0010] Preferably, two support frames are fixedly connected to the outer side of the charging port, and a rotating shaft is rotatably connected inside the two support frames, which makes it easy for the user to open the waterproof cover and drive the waterproof cover to rotate through the rotating shaft, which is more labor-saving.

[0011] Preferably, the outer surface of the rotating shaft is provided with a waterproof cover, and the cross-sectional area of ​​the waterproof cover is larger than the cross-sectional area of ​​the inner side of the charging port, so that the waterproof cover protects the charging port to prevent rainwater from entering the charging port on rainy days and affecting the charging needle.

[0012] Preferably, one side of the waterproof cover is fixedly connected to the same connecting rope, and the other end of the connecting rope is fixedly connected to one side of the protective cover. The connecting rope is made of high-strength fiber material. The protective cover is connected to the waterproof cover through the connecting rope. When charging, it can be hung under the waterproof cover to prevent the protective cover from being lost. At the same time, the connecting rope has good toughness to prevent the connecting rope from breaking.

[0013] The beneficial effects of the utility model are:

[0014] 1. When the charging port stops charging, the photoelectric sensor starts working and controls the alarm light to flash and beep to remind the user to insert the protective cover into the charging port. When the protective cover is inserted into the charging port, the induction plate on one side of the protective cover will pass through the photoelectric sensor set in the charging port. When the photoelectric sensor senses the induction plate, it will control the alarm light to stop working, which solves the problem that the charging needle will rust when it comes into contact with water vapor, resulting in poor contact between the charging needle and the plug, which may cause the charger to heat up and catch fire.

[0015] 2. The protective cover is connected to the waterproof cover through a connecting rope. When charging, it can be hung under the waterproof cover to prevent the protective cover from being lost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When implementing: Figure 1-4 As shown, a charging port of an electric tricycle with a waterproof function includes a charging port 1; a protective component 2, the protective component 2 includes a protective cover 21 located in the charging port 1, a sensing plate 22 is fixedly connected to one side of the protective cover 21, two photoelectric sensors 23 are arranged in the charging port 1 and are axially symmetrically distributed with respect to the axis of the sensing plate 22, and an alarm light 24 is arranged on the outside of the charging port 1. After charging is completed, the protective cover 21 is reinserted into the charging port 1, and the sensing plate 22 on one side of the protective cover 21 will pass through the photoelectric sensor 23 arranged in the charging port 1, and the photoelectric sensor 23 will work after charging is stopped, and the working photoelectric sensor 23 will control the start and stop of the alarm light 24 through electrical signals.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, a charging needle 11 is provided in the charging port 1, and a protective cover 21 is connected to the charging needle 11. Two fixing seats 12 are fixedly connected to the outside of the charging port 1 and are axially symmetrically distributed relative to the axis of the charging port 1. A fixing hole 121 is provided in the fixing seat 12. The length of the induction plate 22 is slightly smaller than the length between the two photoelectric sensors 23. A buzzer is provided in the alarm light 24. When the charging port 1 needs to be installed, the fixing hole 121 on the outside of the charging port 1 is aligned with the mounting hole on the electric vehicle, and the bolt is inserted into the mounting hole through the fixing hole 121 to fix the charging port 1. When the alarm light 24 is working, the bulb in the alarm light 24 will flash, and at the same time, the buzzer in the alarm light 24 will make a sound to remind the user to insert the protective cover 21 into the charging port 1.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, two support frames 3 are fixedly connected to the outside of the charging port 1, and a rotating shaft 4 is rotatably connected inside the two support frames 3. A waterproof cover 5 is sleeved on the outer surface of the rotating shaft 4.

When charging is needed, pull the waterproof cover 5, the waterproof cover 5 will rotate through the rotating shaft 4, and then take out the protective cover 21 on the surface of the charging needle 11, and charging can be carried out.

[0025] When the utility model is in use, when the charging port 1 stops charging, the photoelectric sensor 23 starts working, and controls the alarm light 24 to flash and buzz, so as to remind the user to insert the protective cover 21 into the charging port 1. After the protective cover 21 is inserted into the charging port 1, the induction plate 22 on one side of the protective cover 21 will pass through the photoelectric sensor 23 arranged in the charging port 1. When the photoelectric sensor 23 senses the induction plate 22, it will control the alarm light 24 to stop working, thereby ensuring that the charging needle 11 can be protected when it does not need to be energized, so as to prevent the charging needle 11 from rusting due to contact with water vapor.
