Description

Technical Field

[0001] The present invention relates to the technical field of new energy charging piles, and in particular to a new energy charging pile with an alarm function. Background Art

[0002] With the world's increasing attention to environmental protection and sustainable development, new energy vehicles, as a green mode of travel, have been increasingly widely used and promoted.

[0003] Patent application number 202121989177.0 relates to a charging pile for new energy vehicles with a high-temperature alarm function, specifically comprising a charging pile body and a fixed base, wherein the lower surface of the charging pile body is fixedly mounted with the fixed base. By providing a temperature sensor body, when the device is used, the temperature sensor body is inserted into the interior of the charging pile body, and then the temperature sensor body is placed on the surface of the second support plate. At this time, the clamping plate is bent into an expanded state, and then the temperature alarm body is placed on the upper surface of the first support plate. At this time, the force applied to the clamping plate is canceled, and then the first spring cooperates with the first telescopic rod to drive the clamping plate to reset. When the clamping plate is reset, the temperature alarm body is clamped to a limit position, and then the baffle protects the temperature alarm body to prevent the charging pile body from overheating during long-term charging. In severe cases, it may cause the charging pile body to explode and cause an accident. However, if the device is not put back when the charging plug is put back, no alarm will be issued, which may easily cause a safety hazard. Therefore, a new energy charging pile with an alarm function is proposed to solve the above-mentioned problems. Summary of the invention

The movement of the protrusion 11 will contact the button 14. When the button 14 is pressed, the signal will be transmitted to the alarm 8 through the wire, so that the alarm 8 will sound an alarm, avoiding the user from waiting for charging for a long time without knowing it, avoiding the waste of energy, making the equipment safer, and reducing the incidence of accidents. The inner wall of the cabinet 1 is fixedly connected with a motor 16, and the output end of the motor 16 is fixedly connected with a threaded rod 17. The circumferential surface of the threaded rod 17 is threadedly connected with a fire extinguishing device 18. The inner wall of the cabinet 1 is fixedly connected with a fixing block 19. The inner wall of the cabinet 1 is installed with a smoke alarm device 20. When in use, such as If a fire occurs inside the cabinet 1, the smoke will activate the smoke alarm device 20, which will start the motor 16 through an electrical signal, and will also activate the fire extinguishing device 18. The motor 16 drives the threaded rod 17 to rotate through the output end, and the rotation of the threaded rod 17 drives the fire extinguishing device 18 to move and spray fire extinguishing dry powder, thereby preventing the fire from spreading rapidly, reducing the damage to the charging pile and surrounding facilities caused by the fire, protecting the key components and circuits of the charging pile, reducing the cost of maintenance and replacement, and improving the safety of the equipment; the inner wall of the cabinet door 3 is provided with a barrier mechanism 5 for blocking air, and protective mechanisms 6 are provided on both sides of the charging head 15 to prevent damage from falling;One end of the charging head 15 away from the charging case 7 is installed on the inner wall of the cabinet body 1.

[0017] The blocking mechanism 5 includes a clamping plate 54. One side of the clamping plate 54 close to the cabinet body 1 is fixedly connected with a connecting rod 53. One end of the connecting rod 53 away from the clamping plate 54 is fixedly connected with a mortgaging block 52. A baffle 55 is slidably connected to the inner wall of the cabinet door 3. While extinguishing the fire, the movement of the fire extinguishing device 18 drives the movement of the L-shaped rod 51. The movement of the L-shaped rod 51 drives the mortgaging block 52 to move through the inclined surface. The movement of the mortgaging block 52 drives the connecting rod 53 to move. The movement of the connecting rod 53 drives the clamping plate 54 to move. The movement of the clamping plate 54 will release the limit on the baffle 55, so that the baffle 55 automatically slides down by gravity, thus blocking the heat dissipation port 4, preventing air from continuing to enter, and preventing oxygen in the air from entering and increasing or spreading appropriately, improving the fire extinguishing effect of the alarm 8, further improving the fire extinguishing speed of the device. The left side of the fire extinguishing device 18 is fixedly connected with an L-shaped rod 51; An expansion hinge rod 56 is hinged to the inner wall of the cabinet body 1. The rear side of the expansion hinge rod 56 is hinged to a moving rod 58. A connecting rod 59 is rotatably connected to the inner wall of the moving rod 58. A pulley 510 is fixedly connected to the circumferential surface of the connecting rod 59. A brush barrel 511 is fixedly connected to the circumferential surface of the connecting rod 59. A limiting rod 57 is fixedly connected to the right side of the cabinet door 3. While closing the cabinet door 3, because the expansion hinge rod 56 is hinged to the inner wall of the cabinet body 1, it will drive the moving rod 58 to move through the rotational movement of the expansion hinge rod 56. The moving rod 58 drives the connecting rod 59 to move. The movement of the connecting rod 59 drives the pulley 510 to move. The pulley 510 drives the pulley 510 to rotate through the contact with the limiting rod 57. The rotation of the pulley 510 drives the connecting rod 59 to rotate. The rotation of the connecting rod 59 drives the brush barrel 511 to rotate, thereby cleaning the heat dissipation port 4, preventing the blockage of the heat dissipation port 4 caused by excessive dust, improving the overall heat dissipation effect of the device, reducing the aging and damage of components caused by high temperature, further extending the overall service life of the charging pile, and reducing the maintenance and replacement costs of the device; The clamping plate 54 is slidably connected to the inner wall of the cabinet door 3.

[0018] Working principle: After the charging of the new energy vehicle is completed, the driver puts the charging head 15 back into the charging shell 7. When putting it in, the inclined plane of the charging head 15 contacts the inclined plane of the trapezoidal rod 13, thereby driving the trapezoidal rod 13 to move. The movement of the trapezoidal rod 13 drives the clamping plate 12 to move, the movement of the clamping plate 12 drives the sliding rod 9 to move, and the movement of the sliding rod 9 drives the limiting plate 10 to move. When the charging head 15 enters, it will be pre-clamped by the spring. If the charging head 15 slips after being surface-unlocked, the stability of the device is improved. At the same time, if the driver does not place the charging head 15 properly, the clamping plate 12 will be deflected, which will cause the clamping plate 12 to move and drive the convex block 11 to move. The movement of the convex block 11 will contact the button 14, and the button 14 being pressed will conduct a signal to the alarm 8 through the wire, so that the alarm 8 emits an alarm, avoiding the user waiting for charging for a long time without knowing it, avoiding waste of energy, making the device safer, reducing the accident rate. When in use, if a fire breaks out inside the cabinet 1, the smoke will activate the smoke alarm device 20 to work. The smoke alarm device 20 working will start the motor 16 to work through an electrical signal, and at the same time will also activate the fire extinguishing device 18 to work. The motor 16 working drives the threaded rod 17 to rotate through the output end, and the rotation of the threaded rod 17 drives the fire extinguishing device 18 to move and spray fire extinguishing powder, avoiding the rapid spread of the fire, reducing the damage of the fire to the charging pile and surrounding facilities, protecting the key components and circuits of the charging pile, reducing the maintenance and replacement costs, and improving the safety of the device.

The movement of the connecting rod 53 drives the clamping plate 54 to move. The movement of the clamping plate 54 will release the limit on the partition plate 55, so that the partition plate 55 automatically slides down by gravity, thereby blocking the heat dissipation port 4, avoiding the continuous entry of air, and avoiding the entry of oxygen in the air to increase or spread the fire appropriately, improving the fire extinguishing effect of the alarm 8, and further improving the fire extinguishing speed of the device. When closing the cabinet door 3, because the telescopic hinge rod 56 is hinged to the inner wall of the cabinet 1, it will drive the moving rod 58 to move through the rotation and movement of the telescopic hinge rod 56. The moving rod 58 drives the connecting rod 59 to move. The movement of the connecting rod 59 drives the pulley 510 to move. The pulley 510 contacts the limiting rod 57, thereby driving the pulley 510 to rotate. The rotation of the pulley 510 drives the connecting rod 59 to rotate. The rotation of the connecting rod 59 drives the brush barrel 511 to rotate, thereby cleaning the heat dissipation port 4, avoiding the blockage of the heat dissipation port 4 caused by excessive dust, improving the overall heat dissipation effect of the device, reducing the aging and damage of components caused by high temperature, and further extending the overall service life of the charging pile, and reducing the maintenance and replacement costs of the device.

The movement of the knocking rod 63 drives the slant block 64 to move. When the slant block 64 moves, it contacts the round rod 65 through an inclined surface, thereby driving the slant block 64 to press down. The slant block 64 drives the knocking rod 63 to press down to knock on the cabinet door 3, preventing the heat dissipation holes from being blocked by some relatively stubborn debris. Gently knocking around the heat dissipation holes can loosen these stubborn debris by vibration, making it easier to clean them out, helping to keep the heat dissipation holes unobstructed, maintaining a good heat dissipation effect, and increasing the service life of the device.

The telescopic protection plate 67 will drive the elastic telescopic rod 66 to elastically expand and contract, preventing the charging head 15 from hitting the ground directly and causing damage to the charging head 15, increasing the service life of the charging head 15, and making the overall safety performance of the device better; the rear side of the moving rod 58 is fixedly connected to the positioning block 62. The rear side of the limiting block 61 contacts the knocking rod 63. The slant block 64 contacts the circumferential surface of the round rod 65.

The movement of the positioning block 62 drives the knocking rod 63 to move. The movement of the knocking rod 63 drives the slant block 64 to move.
