Description

Technical Field

[0001] The present invention relates to the field of new energy automobile accessories, and more specifically to a new energy automobile charging pile with a protection function. Background Art

[0002] In recent years, electric vehicles, as a green means of transportation with broad development prospects, will be popularized at an extremely rapid speed in the future, and the future market prospects are also huge. At present, the Chinese government is actively promoting the application and development of new energy vehicles. Charging piles, as an important supporting infrastructure necessary for the development of electric vehicles, have very important social and economic benefits.

[0003] The charging pile is composed of a main body, a charging gun, and a circuit system such as a circuit board arranged in the main body. When charging, the charging gun is inserted into the charging port of the new energy vehicle to complete the charging. Once some users forget to unplug the charging gun from the car charging port after charging, it will cause the charging cable to be straightened when the car is driving, and when the charging cable is stretched to the maximum length, the charging pile will be skewed or the charging cable will be broken, and even the charging gun will be inertially impacted in the car charging port and cause damage to the charging port. When the charging pile suddenly encounters the above situation, it has safety hazards and affects its service life. The Chinese patent with publication number CN113147457B discloses a self-cleaning new energy vehicle charging pile. Through the charging mechanism and limiting mechanism, the charging mechanism is in a closed state when not charging, so as to prevent dust from accumulating on the outside of the charging mechanism and on the wheels of the car. After the tire is fitted with the limiting mechanism, the second wire is connected, thereby connecting the air pump. The output end of the air pump is eccentrically arranged with the sealing plate and is input into the air duct through the air inlet. The air duct is connected with the air cavity, so as to blow air to the outer wall of the display screen to prevent dust from adhering to the outside of the display screen, thereby improving the cleanliness of the display screen and effectively solving the problem that dust is easily attached to the screen of the charging pile. The charging pile limits the front tire through the limiting mechanism and limits the rear tire by pushing the limiting block through the cylinder to prevent the owner from forgetting to pull the charging head out of the charging port due to long-term charging, resulting in the charging head being pulled off. However, this method still has defects. The rear tire can easily cross the limiting block and pull off the charging head, posing a safety hazard. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a new energy vehicle charging pile with a protective function, so that the front and rear tires of the vehicle can be limited by a limiting component when charging, ensuring that the vehicle cannot move during charging, and the tires can be unlocked by a fixing component after the charging is completed and the charging head is returned, avoiding safety problems during and after charging.

[0005] The technical solutions of the present invention are as follows:

[0006] A new energy vehicle charging pile with a protective function comprises a charging pile body and a bottom plate on the ground in front of the charging pile body, wherein the bottom plate is symmetrically provided with buffer grooves, wherein a driving component and a limit component driven by the driving component are arranged in the buffer groove, and a fixing component is arranged on the bottom plate, wherein the limit component is used for limiting and locking a tire driven by the driving component, and the fixing component is used for unlocking the tire after fixing the limit component.

[0007] Preferably, the driving assembly includes a motor fixed in the buffer groove, a gear fixed on the output shaft of the motor, a first rack and a second rack slidably disposed in the buffer groove, and the first rack and the second rack are both meshed with the gear.

[0008] As a preferred embodiment, the limiting assembly includes two rotating sleeves slidably arranged in the buffer groove, a limiting shaft rotatably arranged in the rotating sleeve, and a limiting roller fixedly arranged on the limiting shaft. The top surface of the limiting roller and the top surface of the buffer groove are in the same plane, and the two rotating sleeves are fixedly connected to the first rack and the second rack respectively.

[0009] Preferably, the fixing assembly comprises baffles fixedly arranged on upper and lower sides of the buffer groove, and a fixing plate fixedly arranged on the limiting shaft.

[0010] As a preference, upslopes and downslopes are respectively provided on both sides of the bottom plate.

[0011] As a preference, the charging pile body comprises a charging head, and the charging head is provided with a top block.

[0012] As a preference, a switch is provided on the charging pile body, the switch is electrically connected to the motor, and the top block cooperates with the switch.

[0013] As a preference, the fixing plate and the baffle are both provided with rounded corners and cooperate with each other.

[0014] As a preferred embodiment, the limiting roller is made of stainless steel.

[0015] The beneficial effects of the present invention are

[0016] 1. The present invention is provided with a driving assembly and a limiting assembly. The car drives onto the bottom plate by going uphill and the tire is located on the limiting roller in the buffer groove. Then the charging head is pulled out from the charging pile body. When the charging head is pulled out, the top block releases the switch. The switch starts the motor to rotate through an electrical signal, driving the gear to rotate, so that the first rack, the second rack and the limiting shaft move in opposite directions, so that the two limiting rollers move away from each other until the tire sinks and is located between the two limiting rollers, so as to limit the tire. When the owner forgets to unplug the charging head and starts the car, the tire rotates between the limiting rollers, driving the limiting rollers to rotate in the same way, which can prevent the tire from moving forward, ensure that the tire is always between the limiting rollers, and remind the owner that the charging head is not unplugged to prevent the charging head from being torn off.

[0017] 2. The present invention is provided with a fixing component. When charging is completed and the charging head is inserted into the charging pile body, the top block presses the switch, and the switch starts the motor to rotate in the opposite direction through an electrical signal. The motor drives the gear to rotate in the opposite direction, driving the first rack, the second rack and the two limit shafts to reset. When the two limit rollers approach each other, the tires rise. Then, after the car is started, the tires rotate on the limit rollers, driving the limit shafts to rotate. During the rotation, the fixed plate is blocked by the baffle, so that the two limit rollers stop rotating, and the wheels can leave the buffer groove, ensuring that the wheels are quickly unlocked after the car is charged, making it convenient for the owner to drive away.

[0018] In summary, the present invention has the advantages of protecting the charging pile body and facilitating charging, and is suitable for the field of new energy vehicle accessories. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] like Figures 1 to 6 As shown, a new energy vehicle charging pile with a protective function includes a charging pile body 1 and a base plate 2 on the front ground of the charging pile body 1, a buffer groove 3 is symmetrically opened on the base plate 2, a driving component 4 and a limiting component 5 driven by the driving component 4 are arranged in the buffer groove 3, a fixing component 6 is arranged on the base plate 2, the limiting component 5 is used to limit and lock the tire under the drive of the driving component 4, and the fixing component 6 is used to unlock the tire after fixing the limiting component 5.

[0031] like Figure 2 As shown, the driving assembly 4 includes a motor 41 fixedly disposed in the buffer slot 3, a gear 42 fixedly disposed on the output shaft of the motor 41, a first rack 43 and a second rack 44 slidably disposed in the buffer slot 3, and the first rack 43 and the second rack 44 are both meshed with the gear 42.

[0032] like Figure 3 and Figure 4As shown, the limiting assembly 5 includes two rotating sleeves 51 slidably arranged in the buffer groove 3, a limiting shaft 52 rotatably arranged in the rotating sleeve 51, and a limiting roller 53 fixedly arranged on the limiting shaft 52. The top surface of the limiting roller 53 is in the same plane as the top surface of the buffer groove 3. The two rotating sleeves 51 are fixedly connected to the first rack 43 and the second rack 44 respectively. When in use, when the vehicle wheel enters the buffer groove 3 and is located on the limiting roller 53, when charging is required, the motor 41 drives the gear 42 to rotate. The first rack 43, the second rack 44 and the two limit shafts 52 move in opposite directions, so that the two limit rollers 53 move away from each other until the tire sinks and is located between the two limit rollers 53, thereby limiting the tire. When the owner forgets to unplug the charging head 9 and starts the car, the tire rotates between the limit rollers 53, driving the limit rollers 53 to rotate in the same way, thereby preventing the tire from moving forward and ensuring that the tire is always between the limit rollers 53, thereby reminding the owner that the charging head 9 is not unplugged, thereby preventing the charging head 9 from being torn off.

[0033] like Figure 5 and Figure 6 As shown, the fixing assembly 6 includes a baffle 61 fixedly arranged on the upper and lower sides of the buffer groove 3, and a fixing plate 62 fixedly arranged on the limiting shaft 52. When in use, after the car owner returns the charging head 9, the motor 41 drives the gear 42 to rotate in the opposite direction, driving the first rack 43, the second rack 44 and the two limiting shafts 52 to reset, and when the two limiting rollers 53 approach each other, the tire rises, and then after the car is started, the tire rotates on the limiting roller 53, driving the limiting shaft 52 to rotate. During the rotation, the fixing plate 62 is blocked by the baffle 61, so that the two limiting rollers 53 stop rotating, and the wheel can leave the buffer groove 3, ensuring that the wheel is quickly unlocked after the car is charged, making it convenient for the car owner to drive away.

[0034] like Figure 1 As shown, an uphill slope 7 and a downhill slope 8 are respectively arranged on both sides of the bottom plate 1 to facilitate automobile driving.

[0035] like Figure 4 As shown, the charging pile body 1 includes a charging head 9 , on which a top block 10 is provided.

[0036] like Figures 4 to 6 As shown, a switch 11 is provided on the charging pile body 1, and the switch 11 is electrically connected to the motor 41, and the top block 10 cooperates with the switch 11. When in use, after the charging head 9 is unplugged from the charging pile body 1, the top block 10 releases the switch 11, and the switch 11 starts the motor 41 to rotate through an electrical signal to ensure that the car cannot move during charging. When charging is completed and the charging head 9 is inserted into the charging pile body 1, the top block 10 presses the switch 11, and the switch 11 starts the motor 41 to rotate in the opposite direction through an electrical signal to unlock the tire and facilitate the movement of the car.

[0037] like Figure 6 As shown, both the fixed plate 62 and the baffle plate 61 are provided with rounded corners 12 and cooperate with each other. When the limiting shafts 52 are close to each other, the rounded corners 12 of the baffle plate 61 can drive the fixed plate 62 to rotate to prevent it from getting stuck.

[0038] Embodiment 2

[0039] like Figure 4 As shown, the components that are the same or corresponding to those in the first embodiment are marked with the corresponding figure marks in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that the limiting roller 53 is set to be made of stainless steel.

[0040] Here, in this embodiment, the limiting roller 53 is set to be made of stainless steel, which is friction-resistant. During charging, the tire rotates on the smooth surface of the stainless steel, which can prevent the tire from moving forward and causing the charging head 9 to be torn off.

[0041] Working process

[0042] The car drives onto the bottom plate 1 through the uphill slope 7 and the tire is located on the limiting roller 53 in the buffer groove 3. Then the charging head 9 is unplugged from the charging pile body 1. At the same time, the top block 10 releases the switch 11. The switch 11 starts the motor 41 to rotate through an electrical signal, driving the gear 42 to rotate, so that the first rack 43, the second rack 44 and the limiting shaft 52 move in opposite directions, so that the two limiting rollers 53 move away from each other until the tire sinks and is located between the two limiting rollers 53, and the tire is limited. When the owner forgets to unplug the charging head 9 and starts the car, the tire rotates between the limiting rollers 53, driving the limiting rollers 53 to rotate in the same way, which can prevent the tire from moving forward and ensure that the tire is always between the limiting rollers 53, which can remind the car The main charging head 9 is not pulled out to prevent the charging head 9 from being torn off. When charging is completed, the charging head 9 is inserted into the charging pile body 1, and the top block 10 presses the switch 11. The switch 11 starts the motor 41 to rotate in the opposite direction through an electrical signal. The motor 41 drives the gear 42 to rotate in the opposite direction, driving the first rack 43, the second rack 44 and the two limit shafts 52 to reset. When the two limit rollers 53 approach each other, the tire rises. Then, after the car is started, the tire rotates on the limit roller 53, driving the limit shaft 52 to rotate. During the rotation, the fixed plate 62 is blocked by the baffle 61, so that the two limit rollers 53 stop rotating, and the wheel can leave the buffer slot 3, ensuring that the wheel is quickly unlocked after the car is charged, which is convenient for the owner to drive away.
