Description

Technical Field

[0001] The present invention relates to the technical field related to automobile hybrid power charging equipment, and in particular to an automobile charging equipment slot and a use method thereof. Background Art

[0002] With the depletion of oil resources and the rising gasoline prices, it has become a top priority to find a green and environmentally friendly alternative energy source for cars. At present, solar energy, natural gas and electricity are more considered, which has led to the emergence of a large number of energy-saving and environmentally friendly new energy vehicles. The use of electricity must be charged frequently. A good charging device must ensure both charging safety and charging quality. New energy vehicles are charged by inserting the charging gun into the slot in the charging pile and charging through the charging part that is connected to the slot; In a new energy vehicle fast charging device disclosed in publication number CN107825978A, when the charging gun needs to be pulled out, the charging gun is first held, and then the motor is controlled to work in reverse, so that the sliding block slides to the left to the leftmost end position of the recessed groove, so that the left locking block and the right locking block are respectively retracted into the left sliding groove and the right sliding groove and are respectively disengaged from the left locking groove and the right locking groove, so that the device is restored to the initial position state, so that the gun head is in an unlocked state, and the socket is in a power-off state, and finally the gun head is pulled out from the slot to realize the pulling out of the charging gun; A charging slot device for an electric vehicle disclosed in publication number CN203611897U includes a triangular socket connected to a car battery and a protective cover for blocking rainwater. An opening is provided on the car body, the triangular socket is located in the car body and the front of the triangular socket faces obliquely downward and outward, the protective cover includes an upper end face and an outer side face, one side end edge of the outer side face is vertically hinged to the car body at the opening and can close the opening, the upper end edge of the outer side face is fixedly connected to the upper end face and the upper end face and the outer side face are 90°; a buckle is provided on the other side end edge of the outer side face, and a buckle groove is provided at a corresponding position of the car body, the protective cover can be opened or closed by pressing the buckle, and the protective cover can be popped out by pressing the buckle, and the power cord can be plugged into the triangular socket after opening. When charging is completed, the protective cover can be closed and buckled into the buckle slot through the buckle piece, so as to achieve the purpose of opening the protective cover lock column; when the vehicle needs to be charged, the protective cover on the opening is opened, and the power cord is plugged into the triangular socket for charging. Even if charging is done outdoors on a rainy day, there is no need to worry about water ingress and leakage. The upper end surface and the outer side surface can effectively prevent the entry of rainwater. At the same time, since the front of the triangular socket is tilted downward and outward, it can also effectively prevent rainwater from flowing back into the charging slot along the vehicle body or the power cord. When charging is not needed, the protective cover is closed, which can prevent rainwater and dust from entering without affecting the appearance. A wire clamping groove is provided on the outer surface. When charging, the charging cable is clamped into the wire clamping groove to prevent sliding or falling off of the charging cable. However, the above solution still has the following problems during use: during use, the charging gun is directly inserted into the slot, and then a protective cover is set to protect the slot from dust and water. When the charging gun is inserted back into the charging device, the charging port is not firmly fixed to the charging gun, and the charging gun is easy to slip out of the charging port, which can easily cause electric shock accidents. Moreover, when the charging gun is separated from the slot during use, the slot will be in an open state, and dust and water can still enter the slot, which poses a major safety hazard.

[0003] Therefore, we propose a car charging device slot and a method of use to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a car charging device slot and a method of use, so as to solve the problem of the existing car hybrid charging device slot on the market proposed in the above background technology. During use, the charging gun is directly inserted into the slot, and then the slot is protected from dust and water by setting a protective cover. When the charging gun is inserted back into the charging device, the charging port is not firmly fixed to the charging gun, and the charging gun is easy to slip out of the charging port and easily cause electric shock accidents. Moreover, when the charging gun is separated from the slot during use, the slot will be in an open state, and dust and water can still enter the slot, thereby posing a large safety hazard.

[0005] To achieve the above object, the present invention provides the following technical solution: a car charging device slot, comprising a charging pile, and a slot body is provided on the side of the charging pile, and a charging gun is plugged into the slot body; It also includes: an anti-dropout frame, which is connected to the front side of the slot body by rotating at an equal angle, and the end of the anti-dropout frame is engaged with the concave edge of the outer side of the charging gun, and the anti-dropout frame is set as an "L"-shaped structure as a whole; The sealing plate is slidably connected to the receiving groove, and the receiving groove is opened in the inner wall of the slot body, and the socket of the slot body is set as a circular structure, and the slot body forms a sealed closed structure through the sealing plate.

[0006] Preferably, an adjusting gear is connected to the front bottom of the slot body through the bearing, and a torsion spring is installed between the adjusting gear and the slot body, and a gear ring is meshed on the outer side of the adjusting gear, and the adjusting gear is rotatably connected to the inner wall in the middle of the slot body.

[0007] Preferably, a driven gear is meshed equiangularly on the outer side of the gear ring, and the driven gear bearing is connected to the inner wall in the middle of the slot body, and a worm is integrally installed on the shaft of the driven gear, and the worm passes through the bearing and is connected to the front side of the slot body.

[0008] Preferably, the outer side of the worm is meshingly connected with a worm wheel, and the worm wheel equiangular bearing is connected to the front side of the slot body, and the outer side of the shaft of the worm wheel is fixedly connected with an anti-slip frame, and the end of the anti-slip frame is arranged as an arc structure, and the anti-slip frame forms a limiting and anti-loosening structure through the worm and the worm wheel.

[0009] Preferably, an extrusion plate is fixedly connected to the outer middle part of the worm, and the extrusion plate is rotatably connected to the rotating groove, and the rotating groove is opened at equal angles in the interior of the front part of the slot body, and an air storage bag is fixedly installed in the rotating groove, and the outlet of the air storage bag is connected to the sealing bag.

[0010] Preferably, the extrusion plate is in extrusion contact with the air storage bag through a worm, and the sealing bag connected to the air storage bag is set to a circular ring structure, and the sealing bag is installed on the inner wall of the slot body, and the slot body and the charging gun form an inflatable sealing structure through the sealing bag.

[0011] Preferably, a receiving groove is provided through the inner wall at the rear of the slot body, and the receiving groove is arranged in an "X"-shaped structure, and a sealing plate in the receiving groove is arranged in a fan-shaped structure of a quarter arc.

[0012] Preferably, the side of the sealing plate facing the entrance of the slot body is arranged as a structure inclined toward the center, and a spring is installed between the sealing plate and the receiving slot, and the sealing plate forms an elastic sliding structure between the sealing plates.

[0013] A method for using a car charging device slot comprises the following steps: The first step is to rotate the adjustment gear on the slot body, and then reverse the torsion spring, so that the gear ring drives the driven gear to rotate synchronously. After the driven gear rotates, it will drive the worm to rotate. The worm drives the anti-drop frame to rotate and unfold through the worm gear, thereby making room for the charging gun and the slot body to be plugged in. Step 2: After the charging gun is plugged into the slot body, loosen the adjustment gear and it will rotate left and right under the elastic force of the torsion spring, thereby causing the anti-dropout frame to rotate synchronously. The end of the anti-dropout frame will be engaged with the concave edge on the outside of the charging gun to limit the charging gun, thereby preventing the charging gun from being loosened due to unstable plugging between the charging gun and the slot body, which may cause safety hazards. Step 3: When the worm rotates, it drives the extrusion plate to squeeze the air storage bag, and the air storage bag delivers air to the sealing bag. The sealing bag expands to seal the slot body and the charging gun. The fourth step is that when the charging gun is pulled out of the slot body for use, the sealing plate will be closed under the push of the spring, thereby sealing the slot body to prevent dust and rain from entering the interior of the slot body during the charging process. When the charging gun is returned to its place later, it will be squeezed against the inclined surface of the sealing plate, thereby pushing the sealing plate into the storage slot for easy use next time.

[0014] Compared with the prior art, the automobile charging device slot and the use method of the present invention have the following beneficial effects: when in use, the charging gun and the slot body can be reinforced to prevent loosening, so as to avoid the charging gun being not firmly fixed to the charging gun when the charging gun is put back into the slot, so that the charging gun is easy to slip out of the charging port and easily cause electric shock accidents, and when the charging gun is taken out for use, the slot body can be automatically closed to prevent dust and rain from entering the slot. The specific contents are as follows: 1. The worm and worm gear can be used to drive the anti-drop frame to rotate. After the anti-drop frame rotates, it is used to reinforce the connection between the charging gun and the slot body. Compared with directly inserting the charging gun back into the slot, the connection between the charging gun and the slot body is more stable, thereby preventing the charging gun from slipping out of the charging port and causing an electric shock accident; Furthermore, the arrangement of the gear ring and the driven gear enables the gear ring to rotate after the adjusting gear drives the gear ring to rotate, and the gear ring can synchronously drive the driven gear to rotate, so that the external anti-slip frame can be opened and closed synchronously, thereby improving the use efficiency, and the arc structure at the end of the anti-slip frame is adapted to the external shape of the charging gun, thereby improving the anti-slip reinforcement effect; 2. Through the setting of the air storage bag and the sealing bag, when the worm rotates, it will drive the rotating plate to rotate synchronously. After the rotating plate rotates, it squeezes the air storage bag, and the gas will be transported to the sealing bag. After the sealing bag expands, it seals the gap between the charging gun and the slot, thereby improving the sealing effect and preventing rainwater from seeping in. 3. Through the setting of the storage slot and the sealing plate, the slot can be automatically closed and sealed when the charging gun is taken out of the slot for use. Compared with the existing protective cover, the protective cover is closed when the charging gun is returned to its position and is open when the charging gun is in use, which cannot achieve the dustproof and waterproof effect. The sealing plate can automatically close the slot to achieve a better protection effect; Furthermore, a spring is installed between the sealing plate and the storage slot. The spring can provide a resilient force for the sealing plate so that the charging gun can be automatically closed after being separated from the slot. BRIEF DESCRIPTION OF THE DRAWINGS
