Description

Technical Field

[0001] The utility model relates to the technical field of automobile charging, in particular to a buffer protection device for an electric vehicle charging pile. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It is installed in public buildings, shopping malls, public parking lots, etc. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. More and more people now choose to take or drive new energy vehicles when traveling, and electric vehicles need to use charging piles for charging.

[0003] However, the following problems may occur when using charging piles: (1) When a car approaches a charging pile, the charging pile is smaller than the car and the driver cannot observe the position of the charging pile through the rearview mirror, resulting in the inability to determine the distance between the car and the charging pile, which may cause a collision. (2) Existing charging piles do not have anti-collision bars around them. If the driver does not operate the car accurately, the vehicle may crash into the charging pile and damage the charging pile. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an electric vehicle charging pile buffer protection device, which has the advantages of continuous reminder and buffering of the car from colliding with the charging pile when the car approaches the charging device, thereby reducing the risk of collision between the car and the charging pile.

[0005] In order to achieve the purpose of continuous reminder and buffering of collision between the car and the charging pile when the car approaches the charging device, the utility model provides the following technical solutions:

[0006] A buffer protection device for an electric vehicle charging pile comprises a foundation, a buffer box is slidably connected to the surface of the foundation, a charging device is fixedly connected to the top of the buffer box, and further comprises:

[0007] A buffer pad is slidably connected to the inner wall of the buffer box, and the buffer pad extends to the outside of the buffer box, a first spring is fixedly connected between the buffer pad and the buffer box, an L-shaped tube is fixedly connected to the side wall of the buffer box, a mounting plate is fixedly connected to the top of the L-shaped tube, a rotating column is fixedly connected to the side wall of the mounting plate at the top of the opening of the L-shaped tube, a fan blade is fixedly connected to the side wall of the rotating column, a striking device is fixedly connected to the side wall of the rotating column on both sides of the fan blade, a bell body is fixedly connected to the side wall of the rotating column on both sides of the fan blade, and the striking device is contacted with the bell body, and the pressure difference generated by the sliding of the buffer pad into the inner cavity of the buffer box is used to discharge the gas in the inner cavity of the buffer box to the outside through the L-shaped tube, so that the rotating column can rotate by using the fan blade, and the rotation of the rotating column drives the striking device to rotate and collide with the bell body, thereby generating a sound to remind the driver.

[0008] According to some embodiments, the striking device includes a connecting column, a second spring and a striking column, the connecting column is fixedly installed on the side wall of the rotating column, the end of the connecting column is fixedly connected to the second spring, the end of the second spring is fixedly connected to the striking column, after the striking column collides with the clock body, the second spring bends, so that the striking column can pass over the clock body, so that when the rotating column rotates, it drives the striking column to continuously hit the clock body to produce a sound, the side wall of the connecting column is fixedly connected to the limiting column, and the limiting column is in contact with the striking column. The function of the limiting column can prevent the striking column from continuously hitting the clock body to produce a sound when the rotating column reverses, causing the driver to make a misjudgment, and the bottom of the buffer box located in the inner cavity of the foundation is fixedly connected to a sliding block, and a third spring is fixedly connected between the sliding block and the inner wall of the foundation. The elastic force of the third spring can be used to buffer the collision force generated between the car and the charging device.

[0009] According to some embodiments, a connecting plate is fixedly connected to the side wall of the buffer box, and the connecting plate can protect the third spring in the inner cavity of the foundation.

[0010] The utility model provides a buffer protection device for an electric vehicle charging pile, which has the following beneficial effects:

[0011] (1) When the electric vehicle charging pile buffer protection device approaches the charging device, the car will contact the buffer pad. Under the pressure of the car, the buffer pad slides into the inner cavity of the buffer box, and the pressure in the inner cavity of the buffer box increases, so that the air in the inner cavity of the buffer box is discharged from the inner cavity of the L-shaped tube, and the rotating column is driven to rotate through the fan blades. When the rotating column rotates, it drives the striking device on its side wall to rotate. The striking device will strike the bell body, causing the bell body to make a sound, thereby alerting the driver.

[0012] (2) The buffer protection device of the electric vehicle charging pile utilizes the flexible material of the buffer pad to protect the vehicle when it is in contact with the vehicle. When the reminder is ineffective and the vehicle continues to approach the charging device, the buffer box and the charging device slide on the surface of the foundation through the sliding block, and at the same time squeeze the third spring. The rebound force of the third spring protects the charging device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] 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.

[0019] Reference Figure 1-4 , a buffer protection device for an electric vehicle charging pile, comprising a foundation 1, a buffer box 101 is slidably connected to the surface of the foundation 1, a charging device 102 is fixedly connected to the top of the buffer box 101, and further comprising:

[0020] The inner wall of the buffer box 101 is slidably connected with a buffer pad 2, and the buffer pad 2 extends outward from the buffer box 101, a first spring 201 is fixedly connected between the buffer pad 2 and the buffer box 101, an L-shaped tube 202 is fixedly connected to the side wall of the buffer box 101, a mounting plate 203 is fixedly connected to the top of the L-shaped tube 202, and a rotating column 204 is fixedly connected to the side wall of the mounting plate 203 at the top of the opening of the L-shaped tube 202;

[0021] The side wall of the rotating column 204 is fixedly connected with a fan blade 205, and the side wall of the rotating column 204 on both sides of the fan blade 205 is fixedly connected with a striking device;

[0022] The side walls of the mounting plates 203 on both sides of the rotating column 204 are fixedly connected with a bell body 206, and the striking device can contact the bell body 206;

[0023] It should be noted that: when the car needs to be charged and is close to the charging device 102, the car will come into contact with the buffer pad 2 during the driving process. The buffer pad 2 slides toward the inner cavity of the buffer box 101 under the pressure of the car. At this time, the first spring 201 is squeezed to generate a rebound force. At the same time, the pressure in the inner cavity of the buffer box 101 increases, so that the air in the inner cavity of the buffer box 101 is discharged from the inner cavity of the L-shaped tube 202, and the rotating column 204 is driven to rotate through the fan blades 205. When the rotating column 204 rotates, it drives the striking device on its side wall to rotate, and the striking device will strike the bell body 206, causing the bell body 206 to make a sound, thereby reminding the driver.

[0024] Reference Figure 1-4 The striking device includes a connecting column 3, a second spring 301 and a striking column 302. The connecting column 3 is fixedly mounted on the side wall of the rotating column 204, and the end of the connecting column 3 is fixedly connected to the second spring 301;

[0025] The end of the second spring 301 is fixedly connected with a striking column 302, and the side wall of the connecting column 3 is fixedly connected with a limiting column 303, and the limiting column 303 is in close contact with the striking column 302;

[0026] A sliding block 304 is fixedly connected to the bottom of the inner cavity buffer box 101 located in the foundation 1, and a third spring 305 is fixedly connected between the sliding block 304 and the inner wall of the foundation 1;

[0027] It should be noted that: when the striking device rotates with the rotating column 204, that is, the connecting column 3, the second spring 301 and the striking column 302 rotate, the striking column 302 collides with the bell body 206 when rotating, and a sound is generated. When the rotating column 204 continues to rotate, the bell body 206 squeezes the striking column 302, causing the second spring 301 to bend. Subsequently, the striking column 302 passes over the bell body 206 and is driven by the rotating column 204 to continue to rotate, generating continuous striking sounds, thereby reminding the driver. When the car moves away from the buffer pad 2, the buffer pad 2 returns to its original position under the rebound force of the first spring 201. At this time The L-shaped tube 202 plays the role of suction. At this time, the rotating column 204 rotates in the opposite direction. However, since the limiting column 303 is in contact with the striking column 302, the second spring 301 cannot bend at this time, causing the striking column 302 to be unable to pass over the bell body 206, so that it cannot produce continuous sound, thereby avoiding interference to the driver when leaving. When the buffer pad 2 cannot play a reminder role and the car is still close to the charging device 102, the buffer box 101 and the charging device 102 slide on the surface of the foundation 1 through the sliding block 304, and at the same time squeeze the third spring 305, thereby protecting the charging device 102 again.

[0028] Reference Figure 1-4 , a connecting plate 306 is fixedly connected to the side wall of the buffer box 101, and a shielding plate 307 is fixedly connected to the top of the charging device 102;

[0029] The buffer pad 2 is made of flexible material, and the buffer box 101, the L-shaped tube 202 and the mounting plate 203 are connected;

[0030] It should be noted that the connecting plate 306 will cover the gaps on the surface of the foundation 1 to prevent garbage outside the foundation 1 from entering the inner cavity of the foundation 1 and causing damage to the device. The shield 307 can protect the charging device 102 from sunlight and heavy rain. The flexible material setting of the buffer pad 2 can protect the car when it is in contact with the car.

[0031] Operation method: When the car needs to be charged and approaches the charging device 102, the car will contact the buffer pad 2 during the driving process. The buffer pad 2 slides toward the inner cavity of the buffer box 101 under the pressure of the car. At this time, the first spring 201 is squeezed to generate a rebound force. At the same time, the pressure in the inner cavity of the buffer box 101 increases, so that the air in the inner cavity of the buffer box 101 is discharged from the inner cavity of the L-shaped tube 202, and the rotating column 204 is driven to rotate through the fan blade 205. When the rotating column 204 rotates, it drives the striking device on its side wall to rotate, that is, the connecting column 3, the second spring 301 and the striking column 302 rotate. When the striking column 302 rotates, it collides with the clock body 206 to generate a sound, and the rotating column 2 When the first spring 204 continues to rotate, the bell body 206 squeezes the striking column 302, causing the second spring 301 to bend, and then the striking column 302 passes over the bell body 206 and is driven by the rotating column 204 to continue to rotate, producing continuous striking sounds, thereby reminding the driver, and when the car moves away from the buffer pad 2, the buffer pad 2 returns to its original position under the rebound force of the first spring 201. At this time, the L-shaped tube 202 plays a role of suction, and the rotating column 204 rotates in the opposite direction. However, since the limiting column 303 fits with the striking column 302, the second spring 301 cannot bend at this time, causing the striking column 302 to be unable to pass over the bell body 206, so that it cannot produce continuous sounds, avoiding interference to the driver when leaving;

[0032] When the buffer pad 2 fails to serve as a reminder and the car is still close to the charging device 102, the buffer box 101 and the charging device 102 slide on the surface of the foundation 1 through the sliding block 304, and at the same time squeeze the third spring 305, thereby protecting the charging device 102 again.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
