Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and in particular to an automatic rainproof method and device for charging guns of new energy electric vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures.

[0003] New energy vehicles include four main types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. Unconventional vehicle fuels refer to fuels other than gasoline and diesel. The most common way to charge new energy vehicles is through public outdoor charging stations. When charging outdoors, if it rains, water can easily get into the charging port, causing short circuits and damage to the charging gun or the car's charging port. To address this, we propose an automatic rainproof method and device for charging guns of new energy electric vehicles. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing an automatic rainproof method and device for charging guns of new energy electric vehicles.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic rainproof device for a charging gun of a new energy electric vehicle, comprising a charging gun body, a slot provided at the upper end of the charging gun body, an outer shell installed on the inner side of the slot, an inner shell rotatably connected to the inner side of the outer shell, a second connecting rod provided on the inner side of the outer shell, a first connecting rod rotatably connected to the inner side of the inner shell, a rainproof cloth wrapped around the outer sides of the first connecting rod and the second connecting rod, a sensor installed at the upper end of the outer shell, and a connector for fixing the inner shell to the inner side of the outer shell at the upper end of the inner shell.

[0006] Preferably, a third connecting rod is rotatably connected between the first connecting rod and the second connecting rod, and a rotating cylinder is fixedly connected to the inner side of both the outer shell and the inner shell. The first connecting rod and the second connecting rod are respectively rotatably connected to the inner side of the two sets of rotating cylinders, and a third spring is provided on the inner side of the rotating cylinder.

[0007] Preferably, the upper end of the rain cover is provided with three sets of elastic sheets, and the lower end of the rain cover is fixedly connected with a magnetic sheet.

[0008] Preferably, a rotating head is fixedly connected to one side of the inner shell, and a second connecting shaft is rotatably connected to the inner side of the rotating head. The second connecting shaft is fixedly connected to the outer shell. A second spring is provided on the inner side of the rotating head. One end of the second spring is fixedly connected to the inner wall of the rotating head, and the other end of the second spring is fixedly connected to the second connecting shaft.

[0009] Preferably, the inner side of the card slot is provided with an installation groove, the inner side of the installation groove is fixedly connected with an electric push rod, the upper end of the electric push rod is fixedly connected with a rotating shell, the inner side of the rotating shell is rotatably connected with a first connecting shaft, the first connecting shaft is fixedly connected to the outer shell, and the inner side of the rotating shell is provided with a first spring piece.

[0010] Preferably, the connector includes a rotating rod fixedly connected to both the front and rear ends of the inner shell, a connecting cylinder rotatably connected to the outer side of the rotating rod, a hook fixedly connected to the outer side of the connecting cylinder, a locking block fixedly connected to the outer side of the outer shell, the hook engaging with the locking block, and a fourth spring plate provided on the inner side of the connecting cylinder.

[0011] Preferably, a connecting plate is fixedly connected to the outer side of the connecting cylinder, a pull rod is fixedly connected between the two sets of connecting plates, an installation block is fixedly connected to the upper end of the inner shell, a motor is installed on the upper end of the installation block, a connecting rope is wound around the output end of the motor, and the connecting rope is fixedly connected to the pull rod.

[0012] An automatic rainproof method for charging guns of new energy electric vehicles, comprising:

[0013] Step 1: When charging the electric vehicle, use a sensor to detect if there is rain. Once rain is detected, activate the electric push rod to push the outer casing out from the inside of the slot.

[0014] Step 2: Use the first spring to drive the first connecting shaft to rotate, which in turn drives the outer shell to rotate, so that the outer shell is perpendicular to the charging gun body;

[0015] Step 3: Start the motor to wind up the connecting rope, pull the lever to make the connecting plate drive the connecting cylinder to rotate on the rotating rod, so that the hook and the block are separated. At this time, the second spring will drive the rotating head to rotate and open the inner shell.

[0016] Step 4: After the inner shell is opened, the third spring will drive the first connecting rod and the second connecting rod to rotate, so that the rain cover will wrap around the first connecting rod and the second connecting rod, and pop outward under the action of the elastic piece. The magnetic piece will make the rain cover stick to the vehicle body, and the rain cover will cover the charging connection.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The outer casing can be secured by a slot for easy concealment. The first spring plate drives the first connecting shaft to rotate, which in turn drives the outer casing to rotate, making the outer casing perpendicular to the charging gun body. This facilitates the rain cover covering the connection point. The motor can rewind the connecting rope and pull the lever, causing the connecting plate to rotate the connecting cylinder on the rotating rod, separating the hook and the locking block. At this time, the second spring plate will drive the rotating head to open the inner casing. The outer and inner casings can conceal the first and second connecting rods, facilitating the rolling and concealment of the rain cover. After the inner casing is opened, the first, second, and third connecting rods will form a straight rod, facilitating the rolling and unfolding of the rain cover. The third spring plate will drive the first and second connecting rods to rotate, allowing the rain cover to wrap around them. The elastic sheet allows the rain cover to pop out easily, ensuring that the magnetic sheet can adhere to the vehicle body. The rain cover covers the charging connection point, preventing rainwater from entering and causing a short circuit during charging. Attached Figure Description

A second connecting rod 9 is provided inside the shell 3. A first connecting rod 8 is rotatably connected to the inner side of the inner shell 4. A rainproof cloth 10 is wrapped around the outer sides of the first connecting rod 8 and the second connecting rod 9. A sensor 5 is installed at the upper end of the shell 3. A connector 6 for fixing the inner shell 4 to the inner side of the shell 3 is provided at the upper end of the inner shell 4.

[0033] In this embodiment, a third connecting rod 18 is rotatably connected between the first connecting rod 8 and the second connecting rod 9. Rotary cylinders 19 are fixedly connected to the inner sides of both the outer shell 3 and the inner shell 4. The first connecting rod 8 and the second connecting rod 9 are rotatably connected to the inner sides of the two sets of rotating cylinders 19, and a third spring piece 20 is provided on the inner side of the rotating cylinder 19.

[0034] Specifically, after the inner shell 4 is opened, the first connecting rod 8, the second connecting rod 9 and the third connecting rod 18 will form a straight rod, which facilitates the rolling and unfolding of the rain cover 10. The third spring piece 20 will drive the first connecting rod 8 and the second connecting rod 9 to rotate, so that the rain cover 10 can be wrapped around the first connecting rod 8 and the second connecting rod 9.

[0035] In this embodiment, the upper end of the rainproof cloth 10 is provided with three sets of elastic sheets 101, and the lower end of the rainproof cloth 10 is fixedly connected with a magnetic sheet 102.

[0036] Specifically, the elastic sheet 101 allows the rain cover 10 to pop out easily, ensuring that the magnetic sheet 102 can be attached to the vehicle body. The rain cover 10 is used to cover the charging connection point to prevent rainwater from entering and causing a short circuit during charging.

[0037] In this embodiment, a rotating head 15 is fixedly connected to one side of the inner shell 4, and a second connecting shaft 17 is rotatably connected to the inner side of the rotating head 15. The second connecting shaft 17 is fixedly connected to the outer shell 3. A second spring piece 16 is provided on the inner side of the rotating head 15. One end of the second spring piece 16 is fixedly connected to the inner wall of the rotating head 15, and the other end of the second spring piece 16 is fixedly connected to the second connecting shaft 17.

[0038] Specifically, the second spring 16 will drive the rotating head 15 to rotate, causing the inner shell 4 to open, so that the first connecting rod 8, the second connecting rod 9, and the third connecting rod 18 can be connected into a straight rod.

[0039] In this embodiment, the inner side of the slot 2 is provided with an installation slot 7, the inner side of the installation slot 7 is fixedly connected with an electric push rod 11, the upper end of the electric push rod 11 is fixedly connected with a rotating shell 12, the inner side of the rotating shell 12 is rotatably connected with a first connecting shaft 13, the first connecting shaft 13 is fixedly connected with the outer shell 3, and the inner side of the rotating shell 12 is provided with a first spring piece 14.

[0040] Specifically, the outer shell 3 can be locked in place by the slot 2, making it easy to hide the outer shell 3. The first spring piece 14 drives the first connecting shaft 13 to rotate, thereby driving the outer shell 3 to rotate, so that the outer shell 3 is perpendicular to the charging gun body 1, which makes it easy for the rain cover 10 to cover the connection.

[0041] In this embodiment, the connector 6 includes a rotating rod 61 fixedly connected to both the front and rear ends of the inner shell 4, a connecting cylinder 62 rotatably connected to the outer side of the rotating rod 61, a hook 64 fixedly connected to the outer side of the connecting cylinder 62, a locking block 610 fixedly connected to the outer side of the outer shell 3, the hook 64 and the locking block 610 engaging with each other, and a fourth spring piece 63 provided on the inner side of the connecting cylinder 62.

[0042] A connecting plate 65 is fixedly connected to the outside of the connecting cylinder 62, and a pull rod 66 is fixedly connected between the two sets of connecting plates 65. An installation block 67 is fixedly connected to the upper end of the inner shell 4. A motor 68 is installed on the upper end of the installation block 67. A connecting rope 69 is wound around the output end of the motor 68, and the connecting rope 69 is fixedly connected to the pull rod 66.

[0043] Specifically, the motor 68 can wind up the connecting rope 69 and pull the lever 66 to make the connecting plate 65 drive the connecting cylinder 62 to rotate on the rotating rod 61, so that the hook 64 separates from the locking block 610.

[0044] An automatic rainproof method for charging guns of new energy electric vehicles, comprising:

[0045] Step 1: When charging the electric vehicle, the sensor 5 is used to detect whether there is rain. Once rain is detected, the electric push rod 11 is activated to push the outer casing 3 out from the inside of the slot 2.

[0046] Step 2: Use the first spring piece 14 to drive the first connecting shaft 13 to rotate, thereby driving the outer shell 3 to rotate, so that the outer shell 3 is perpendicular to the charging gun body 1;

[0047] Step 3: Start the motor 68 to wind up the connecting rope 69, pull the lever 66 to make the connecting plate 65 drive the connecting cylinder 62 to rotate on the rotating rod 61, so that the hook 64 separates from the locking block 610. At this time, the second spring 16 will drive the rotating head 15 to rotate and open the inner shell 4.

[0048] Step 4: After the inner shell 4 is opened, the third spring 20 will drive the first connecting rod 8 and the second connecting rod 9 to rotate, so that the rain cover 10 will wrap around the first connecting rod 8 and the second connecting rod 9, and pop outward under the action of the elastic piece 101. The magnetic piece 102 will be used to make the rain cover 10 stick to the vehicle body, and the rain cover 10 will cover the charging connection.

[0049] Working principle: Sensor 5 detects whether it is raining outside. After detecting rain, the electric push rod 11 is activated to push the outer shell 3 out from the inside of the slot 2. The first spring 14 drives the first connecting shaft 13 to rotate, which in turn drives the outer shell 3 to rotate, so that the outer shell 3 is perpendicular to the charging gun body 1. The motor 68 is activated to wind up the connecting rope 69. Pulling the pull rod 66 causes the connecting plate 65 to drive the connecting cylinder 62 to rotate on the rotating rod 61, so that the hook 64 separates from the locking block 610. At this time, the second spring 14 is activated to push the outer shell 3 out of the slot 2. 16 will drive the rotating head 15 to rotate, causing the inner shell 4 to open. After the inner shell 4 is opened, the first connecting rod 8, the second connecting rod 9 and the third connecting rod 18 will form a straight rod. At this time, the third spring 20 will drive the first connecting rod 8 and the second connecting rod 9 to rotate, causing the rain cover 10 to wrap around the first connecting rod 8 and the second connecting rod 9, and pop outward under the action of the elastic piece 101. The magnetic piece 102 will be used to make the rain cover 10 stick to the vehicle body, and the rain cover 10 will cover the charging connection.
