[0002] A car charging pile is a device used to charge electric vehicles. It can transfer electricity from the power grid to the battery of the electric vehicle for driving or storing electricity to ensure the normal driving of the electric vehicle.

[0003] Generally, there are many electronic components inside the new energy vehicle charging pile, which may generate heat during operation. To prevent them from overheating and damage, heat dissipation holes are opened on the outer wall of the charging pile. These heat dissipation holes are generally fixed and cannot be closed. On rainy days, rainwater may be blown into the charging pile through the heat dissipation holes by the wind, causing damage to the electronic components inside. The protection is too low, and when the vehicle approaches the charging pile, the driver may make an error in operation, causing the charging pile to be hit and damaged. The charging pile does not have an alarm function and cannot warn the driver. Therefore, a parking lot charging pile anti-collision alarm is proposed to solve the above problems.

[0029] 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.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment of a parking lot charging pile anti-collision alarm, comprising a body 1, an inner wall on the right side of the body 1 is elastically connected with a shielding plate 2 through a limit spring 5, the shielding plate 2 is slidably connected to the inner wall on the right side of the body 1, a heat dissipation hole is provided at the position of the body 1 corresponding to the shielding plate 2, and a guide groove is provided on the outer wall of the body 1 to fit the shielding plate 2, so that the shielding plate 2 can only move up and down on the inner wall of the guide groove, one end of the limit spring 5 is fixedly connected to the bottom end of the outer wall of the shielding plate 2, and the other end of the limit spring 5 is fixedly connected to the inner wall of the body 1, the function of the limit spring 5 is that when the shielding plate 2 is pulled down, when it is not fixed, the shielding plate 2 will be automatically restored to its initial position by elasticity, and the top of the outer wall of the body 1 is fixedly connected with an alarm 3.

[0031] Reference Figure 2-Figure 4The inner wall of the right bottom end of the body 1 is elastically connected with a block 9 through a connecting spring 10, and the block 9 is slidably connected to the inner wall of the body 1. The block 9 is in a U-shape, and a pressing block is arranged at one end, and the other end fits in the slot of the shielding plate 2. A slot is provided at the bottom end of the inner side wall of the shielding plate 2, and the block 9 is engaged with the inner wall of the slot. The engagement between the two moves the shielding plate 2 to the bottommost position of the outer wall of the body 1 for fixing, thereby preventing it from being subjected to the elastic action of the limit spring 5 and automatically restoring to the initial position. One end of the connecting spring 10 is fixedly connected to the inner wall of the bottom end of the body 1, and the other end of the connecting spring 10 is fixedly connected to the bottom end of the outer wall of the block 9. The function of the connecting spring 10 is that when the block 9 is pressed to the inner wall of the body 1, it can be automatically reset by the elastic action of the connecting spring 10. A fixing column 6 is fixedly connected to the surface of the body 1, and the outer wall of the fixing column 6 is elastically connected to the contact plate 4 through a reset spring 12.

[0032] Reference Figure 2 and Figure 4 One end of the return spring 12 is fixedly connected to the outer wall of the fixed column 6, and the other end of the return spring 12 is fixedly connected to the inner side wall of the contact plate 4. The function of the return spring 12 is that when the contact plate 4 is hit, the elastic action of the return spring 12 can reduce the buffering and reset it at the same time. A contact switch 8 is provided on the surface of the contact plate 4, and the contact switch 8 is connected to the alarm 3 by wire. When the vehicle hits the contact plate 4, it will first contact the contact switch 8, so that the contact switch 8 transmits an electrical signal to let the alarm 3 sound an alarm, wherein the contact switch 8 and the alarm 3 are both prior art, and a buffer component is provided on the inner wall of the fixed column 6.

[0033] Reference Figure 4 The buffer assembly includes a sliding column 7, and the bottom end of the outer wall of the sliding column 7 contacts with a damping ring 11. The damping ring 11 is a prior art and is composed of multiple groups of hard rubber. When the sliding column 7 moves on the inner wall of the fixed column 6, it will contact the damping ring 11, so that the damping ring 11 can reduce the impact on it. The top end of the outer wall of the sliding column 7 is fixedly connected to the outer side wall of the contact plate 4, and the sliding column 7 is slidably connected to the inner wall of the fixed column 6. Multiple groups of damping rings 11 are provided, and multiple groups of damping rings 11 are slidably connected to the inner wall of the fixed column 6.

[0034] Working principle: when it rains, the shielding plate 2 will block and close the heat dissipation vents of the body 1, thereby preventing rainwater from entering the inner wall of the body 1 from the ventilation and heat dissipation vents. When it is necessary to open the shielding plate 2, you can first grab the handle of the shielding plate 2 and pull the shielding plate 2 to move downward on the inner wall of the body 1. During the descent process, the limit spring 5 will be elastically compressed until the shielding plate 2 is completely moved to the bottom end, the outer wall of its bottom end will squeeze the arc surface of the card block 9, and allow the card block 9 to move on the inner wall of the body 1, and allow the connecting spring 10 to be elastically compressed until the shielding plate 2 completely passes through the card block 9. The card block 9 will be elastically acted upon by the connecting spring 10 to restore it to its initial position, thereby engaging with the card slot at the current position of the shielding plate 2, thereby fixing the downwardly deployed position of the shielding plate 2. At the same time, when the card block 9 is pressed to cancel the engagement with the card slot at the bottom end of the shielding plate 2, the shielding plate 2 will be elastically acted upon by the connecting spring 10 to restore it to its initial position.

[0035] At the same time, when the device is in use, when the vehicle accidentally collides with the body 1, it will first contact the contact plate 4 and squeeze the contact switch 8, so that the alarm 3 will sound through the contact switch 8, thereby alerting the vehicle owner of the collision. At the same time, when the contact plate 4 is hit, it will squeeze the sliding column 7 to move on the inner wall of the fixed column 6, so that the sliding column 7 squeezes the damping ring 11, thereby increasing a certain buffering effect when the sliding column 7 moves through the damping ring 11. At the same time, when the contact plate 4 moves, the return spring 12 will also be elastically compressed, thereby increasing double buffering when the contact plate 4 is contacted, thereby ensuring the use of the charging pile.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
