Description

Technical Field

[0001] This application relates to the technical field of charging gun devices, and particularly to a fingerprint lock charging gun. Background Art

[0002] With the rapid development of the electric vehicle industry, the market demand for charging facilities is increasing day by day. To meet this demand, various types of electric vehicle charging stations and mobile chargers have emerged. However, the potential safety hazards during use have gradually become one of the issues of social concern.

[0003] Since many people own the same type of electric vehicle and their charging piles are also the same, for private charging piles, unauthorized persons using others' accounts to charge not only wastes resources but also causes economic losses. Therefore, some existing charging guns are equipped with fingerprint modules for fingerprint recognition. However, due to the charging guns being parked exposed, the fingerprint recognition area of the fingerprint module is easily scratched or accumulate dust in the environment. If there is rain in the environment, it is also easy to form water stains in the fingerprint recognition area, affecting people's use, thus making it inconvenient to quickly and accurately identify fingerprints. Summary of the Invention

[0004] In order to improve the convenience of the fingerprint lock charging gun during operation, this application provides a fingerprint lock charging gun.

[0005] This application provides a fingerprint lock charging gun, adopting the following technical solutions: A fingerprint lock charging gun includes a charging gun body. A fingerprint module for controlling the charging gun to be powered on is installed on the charging gun body. A shielding component for shielding the fingerprint module is installed on the charging gun body. A protection component for protecting the fingerprint module is installed on the charging gun body. The protection component includes a mounting frame, the mounting frame is installed on the charging gun body, a sliding cylinder is installed on the mounting frame, a sliding rod is slidably installed on the sliding cylinder, one end of the sliding rod is arranged inside the sliding cylinder, and the other end is arranged outside the sliding cylinder. A pressing plate is installed at the end of the sliding rod arranged inside the sliding cylinder. A first spring is connected to the pressing plate, and the end of the first spring away from the pressing plate is connected to the sliding cylinder. A first slider is slidably installed on the mounting frame. A pushing plate is installed on the first slider, the pushing plate is connected to the sliding rod. A first push rod is installed on the first slider, and a first shielding plate for shielding the fingerprint module is installed on the first push rod.

[0006] By adopting the above technical solution, the fingerprint module is initially shielded by the shielding component, avoiding the entire fingerprint module being exposed, preventing dust from accumulating on the fingerprint module, and enhancing the service life of the fingerprint module. When fingerprint recognition is required, by pushing the push plate, the push plate drives the sliding rod to retract into the sliding cylinder, the push plate drives the first slider to slide on the mounting rack, and the first slider drives the first shielding plate to move out above the fingerprint module, enabling the fingerprint recognition area of the fingerprint module to be quickly exposed, thus facilitating the user to quickly perform fingerprint verification. After the fingerprint verification is completed, the first spring rebounds to push the sliding rod and the first slider back to their original positions, enabling the first shielding plate to quickly move above the fingerprint module to shield the fingerprint module, protecting the fingerprint module again, preventing dust accumulation and also preventing scratches on the fingerprint module, maintaining the cleanliness of the fingerprint module, and being beneficial to improving the user experience of the fingerprint lock charging gun.

[0007] In a specific feasible implementation, a rotating frame is rotatably mounted on the mounting rack, a second slider is slidably mounted on the rotating frame, a first fixing rod is mounted on the second slider, the first fixing rod passes through the first push rod and is rotatably connected to the first push rod, a third slider is slidably mounted on the rotating frame, the third slider and the second slider are respectively arranged at both ends of the rotating frame, and a second fixing rod is mounted on the third slider; a fourth slider is slidably mounted on the mounting rack, a second push rod is mounted on the fourth slider, the second fixing rod passes through the second push rod and is rotatably connected to the second push rod, and a second shielding plate that shields the fingerprint module is mounted on the second push rod.

[0008] By adopting the above technical solution, through the sliding connection of the second slider and the third slider with the rotating frame, the rotating connection of the first push rod with the first fixing rod, and the rotating connection of the second push rod with the second fixing rod, the situation that the first push rod and the second push rod are jammed with the rotating frame when the rotating frame rotates is ingeniously avoided, and the movement path of the second push rod is restricted by the fourth slider, enabling the second push rod to perform a linear motion. The rotating frame is used to control and link the second push rod, enabling the first push rod and the second push rod to move in opposite directions, so that the first shielding plate and the second shielding plate can move away from and approach each other. By using the way of clamping and separating the first shielding plate and the second shielding plate, it is convenient to quickly expose the touch area of the fingerprint module and quickly shield above the fingerprint module for shielding protection.

[0009] In a specific feasible implementation, a first installation groove is formed in the first push rod. A first lifting rod is slidably installed on the first push rod. One end of the first lifting rod extends into the first installation groove, and the other end extends out of the first installation groove. The end of the first lifting rod extending out of the first installation groove is connected to the first shielding plate. A second spring is sleeved on the first lifting rod. One end of the second spring is connected to the first shielding plate, and the other end is connected to the first push rod. A first limiting plate is installed on the first push rod. The first limiting plate is arranged in the first installation groove. A first convex block is installed at the end of the first lifting rod extending into the first installation groove. The first convex block passes through the first limiting plate and is slidably connected to the first limiting plate. A first pressing column for pressing the first convex block is installed on the second push rod.

[0010] In a specific feasible implementation, a second installation groove is formed in the second push rod. A second lifting rod is slidably installed on the second push rod. One end of the second lifting rod extends into the second installation groove, and the other end extends out of the second installation groove. The end of the second lifting rod extending out of the second installation groove is connected to the second shielding plate. A third spring is sleeved on the second lifting rod. One end of the third spring is connected to the second shielding plate, and the other end is connected to the second push rod. A second limiting plate is installed on the second push rod. The second limiting plate is arranged in the second installation groove. A second convex block is installed on the second lifting rod. The second convex block passes through the second limiting plate and is slidably connected to the second limiting plate. A second pressing column for pressing the second convex block is installed on the first push rod.

[0011] By adopting the above technical solution, the first shielding plate and the second shielding plate are set to be capable of lifting adjustment. When the first shielding plate and the second shielding plate shield above the fingerprint module, the first shielding plate and the second shielding plate will descend to reduce the distance from the fingerprint module, preventing dust from falling in, and can more effectively protect the fingerprint module.

[0012] In a specific feasible implementation, a first cleaning cotton is installed on the first shielding plate, and a second cleaning cotton is installed on the second shielding plate.

[0013] By adopting the above technical solution, cleaning cotton is added to the first shielding plate and the second shielding plate. First, the cleaning cotton can absorb the moisture in the touch area of the fingerprint module, keep it dry, and enhance the recognition effect. Second, when the first shielding plate and the second shielding plate leave above the fingerprint module, the cleaning cotton can wipe the fingerprint module, wipe off pollutants such as dust and water stains, enhance the cleaning effect, and is beneficial to enhancing the use performance of the charging gun.

[0017] By adopting the above technical solution, the movement of the sliding cover is controlled by turning the dial button, so that the fingerprint touch recognition area of ​​the fingerprint module can be quickly opened and closed.

[0018] In a specific possible implementation manner, a blocking piece is installed on the push plate, and a pushing piece for pushing the blocking piece is installed on the sliding cover.

[0019] By adopting the above technical solution, a push piece is installed on the sliding cover, and the push piece is used to push the blocking piece to control the movement of the first sliding block, so that when the user opens the sliding cover, the first shielding plate can be moved to the side of the fingerprint module together with the first push rod. When the sliding cover is opened, the fingerprint module is exposed, which is convenient for the operator to use.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. The shielding component is used to initially shield the fingerprint module, so as to avoid the entire fingerprint module being exposed outside and prevent dust from accumulating on the fingerprint module, thereby enhancing the service life of the fingerprint module. When fingerprint recognition is required, the push plate is pushed, and the push plate drives the slide bar to be retracted in the slide barrel, and the push plate drives the first slider to slide on the mounting frame, and the first slider drives the first shielding plate to move out from above the fingerprint module, so that the fingerprint recognition area of ​​the fingerprint module can be quickly exposed, thereby facilitating the user to quickly verify the fingerprint; after the fingerprint verification is completed, the first spring rebounds to push the slide bar and the first slider back to their positions, so that the first shielding plate can be quickly moved to the top of the fingerprint module to shield the fingerprint module, and the fingerprint module is protected again to prevent dust accumulation and scratches on the fingerprint module, thereby keeping the fingerprint module clean, which is conducive to improving the user experience of the fingerprint lock charging gun.

Detailed Description of the Embodiment

[0032] The following will further elaborate on the present application in conjunction with the attached Figure 1-10 drawings.

[0033] Embodiment: An embodiment of the present application discloses a fingerprint lock charging gun. Refer to Figure 1and Figure 2 , including a charging gun body 1, on which is installed a fingerprint module 2 for controlling the power supply of the charging gun through fingerprint recognition, and on which is installed a shielding component 3 and a protection component 4 for shielding the fingerprint recognition touch area of ​​the fingerprint module 2. In this embodiment, the fingerprint module 2 is a prior art and will not be described in detail in the embodiments of this application.

[0034] Reference Figure 3 The shielding component 3 includes a slide rail 31, which is fixedly mounted on the charging gun body 1. A slide cover 32 is slidably mounted on the slide rail 31. The slide cover 32 is a C-shaped cover plate buckled on the charging gun body 1. A buckle 33 is fixedly mounted on the slide cover 32, and an anti-slip pattern is provided on the buckle 33.

[0035] By turning the dial button 33 to control the movement of the sliding cover 32, the fingerprint touch recognition area of ​​the fingerprint module 2 can be quickly opened and closed. By covering the fingerprint module 2 with the sliding cover 32, dust and water in the environment can be initially prevented from accumulating on the fingerprint module 2, and the fingerprint module 2 can be initially protected.

[0036] Reference Figure 4 , Figure 5 and Figure 10 The protection component 4 includes a mounting frame 41, which is fixedly mounted on the charging gun body 1. The mounting frame 41 is a U-shaped frame. A slide 421 is fixedly mounted on the mounting frame 41. A slide rod 422 is slidably mounted on the slide 421. One end of the slide rod 422 extends into the slide 421, and the other end extends out of the slide 421. A pressure plate 423 is fixedly mounted on the end of the slide rod 422 extending into the slide 421. A first spring 424 is fixedly mounted on the pressure plate 423. The end of the first spring 424 away from the pressure plate 423 is fixedly connected to the slide 421. A first slider 425 is slidably mounted on the mounting frame 41. A push plate 426 is fixedly connected to the first slider 425. The end of the push plate 426 away from the first slider 425 is fixedly connected to the slide rod 422. A blocking piece 4261 is arranged on the push plate 426. A push piece 34 for pushing the blocking piece 4261 to move is fixedly mounted on the sliding cover 32.

[0037] Reference Figure 5 and Figure 6 A first push rod 427 is fixedly mounted on the first slider 425 , a first shielding plate 428 shielding the top of the fingerprint module 2 is fixedly mounted on the first push rod 427 , and a first cleaning cotton 429 is fixedly mounted on the first shielding plate 428 .

[0038] Reference Figure 5 , Figure 6 and Figure 10, when fingerprint recognition is required, the operator pushes the sliding cover 32 towards the baffle 4261. When the sliding cover 32 drives the pushing piece 34 to move until it abuts against the baffle 4261, the pushing piece 34 will push the baffle 4261, causing the baffle 4261 to drive the sliding rod 422 to move and retract into the sliding cylinder 421. When the sliding rod 422 retracts into the sliding cylinder 421, it will compress the first spring 424. When the pushing piece 34 pushes the baffle 4261 and the push plate 426 to move, the push plate 426 will drive the first slider 425 to slide on the mounting bracket 41. The first slider 425 drives the first push rod 427 to move towards the sliding cylinder 421. The first push rod 427 drives the first shielding plate 428 to move to the side of the fingerprint module 2, and during the movement, the touch area of the fingerprint module 2 is wiped by the first cleaning cotton 429, so that the touch area remains clean when it is exposed, which is beneficial to enhancing the accuracy of fingerprint reading and recognition and enabling quick recognition.

[0039] After fingerprint recognition is completed and the charging gun is powered on, the sliding cover 32 is pushed to move away from the sliding cylinder 421. After the baffle 4261 loses the thrust of the pushing piece 34, the first spring 424 pushes the sliding rod 422 to extend out of the sliding cylinder 421. The sliding rod 422 drives the first slider 425 to slide on the mounting bracket 41 through the push plate 426. The first slider 425 drives the first push rod 427 to move to reposition the first shielding plate 428 and the first cleaning cotton 429 above the fingerprint module 2 to protect the fingerprint recognition touch area of the fingerprint module 2.

[0040] Refer to Figure 5 and Figure 6 , a rotating frame 431 is rotatably mounted on the mounting bracket 41. The rotating frame 431 has an I-shaped frame structure. A second slider 432 is slidably mounted on the rotating frame 431. A first fixed rod 433 is fixedly mounted on the second slider 432. The first fixed rod 433 passes through the first push rod 427 and is rotatably connected to the first push rod 427. A third slider 434 is slidably mounted on the rotating frame 431. The third slider 434 and the second slider 432 are oppositely arranged at both ends of the rotating frame 431. A second fixed rod 435 is fixedly mounted on the third slider 434. A fourth slider 436 is slidably mounted on the mounting bracket 41. The fourth slider 436 and the first slider 425 are oppositely arranged. A second push rod 437 is fixedly mounted on the fourth slider 436. The second fixed rod 435 passes through the second push rod 437 and is rotatably connected to the second push rod 437. A second shielding plate 438 that shields above the fingerprint module 2 is connected to the second push rod 437. A second cleaning cotton 439 is fixedly mounted on the second shielding plate 438.

[0041] When the first slider 425 moves on the mounting frame 41 toward the slide 421, the first slider 425 drives the first push rod 427 to pull one end of the rotating frame 431 to rotate in the direction of the slide 421, and the other end of the rotating frame 431 drives the second push rod 437 to move in the direction away from the slide 421, and is slidably connected to the rotating frame 431 through the second slider 432 and the third slider 434, the first push rod 427 is rotationally connected to the first fixed rod 433, and the second push rod 437 is rotationally connected to the second fixed rod 435, which cleverly avoids the first push rod 427 and the second push rod 437 from getting stuck with the rotating frame 431 when the rotating frame 431 rotates, and the fourth slider 436 is used to limit the moving path of the second push rod 437, so that the second push rod 437 moves in a straight line. The rotating frame 431 is used to control the linkage of the second push rod 437, so that the first push rod 427 and the second push rod 437 can move in opposite directions, so that the first shielding plate 428 and the second shielding plate 438 can move away from and close to each other, which is convenient for quickly exposing the touch area of ​​the fingerprint module 2 and quickly shielding the top of the fingerprint module 2 for protection.

[0042] Reference Figure 7 , Figure 8 and Figure 9 A first mounting groove 4271 is provided on the first push rod 427, and a first lifting rod 4272 is slidably installed on the first push rod 427. One end of the first lifting rod 4272 extends into the first mounting groove 4271, and the other end extends out of the first mounting groove 4271. One end of the first lifting rod 4272 extending out of the first mounting groove 4271 is fixedly connected to the first baffle plate 428. A second spring 4273 is sleeved on the first lifting rod 4272, and one end of the second spring 4273 is fixedly connected to the first baffle plate 428, and the other end is fixedly connected to the first push rod 427. A first limiting plate 4274 is fixedly mounted on the first push rod 427, and the first limiting plate 4274 is disposed in the first mounting groove 4271. The first limiting plate 4274 is disposed above the first lifting rod 4272. A first protrusion 4275 is fixedly mounted on the first lifting rod 4272. The first protrusion 4275 is configured in an arc shape at one end away from the first shielding plate 428. The first protrusion 4275 passes through the first limiting plate 4274 and is slidably connected to the first limiting plate 4274. A first pressing column 4276 that pushes the first protrusion 4275 is fixedly mounted on the second push rod 437.

[0043] A second installation groove 4371 is formed in the second push rod 437. A second lifting rod 4372 is slidably installed on the second push rod 437. One end of the second lifting rod 4372 extends into the second installation groove 4371, and the other end extends out of the second installation groove 4371. The end of the second lifting rod 4372 extending out of the second installation groove 4371 is connected to a second shielding plate 438. A third spring 4373 is sleeved on the second lifting rod 4372. One end of the third spring 4373 is fixedly connected to the second shielding plate 438, and the other end is fixedly connected to the second push rod 437. A second limiting plate 4374 is fixedly installed on the second push rod 437. The second limiting plate 4374 is arranged in the second installation groove 4371 and above the second lifting rod 4372. A second convex block 4375 is fixedly installed on the second lifting rod 4372. The end of the second convex block 4375 away from the second shielding plate 438 is arc-shaped. The second convex block 4375 passes through the second limiting plate 4374 and is slidably connected to the second limiting plate 4374. A second pressing column 4376 for pressing the second convex block 4375 is fixedly installed on the first push rod 427.

[0044] Figure 7 and Figure 8 When the first shielding plate 428 and the second shielding plate 438 move away from each other to expose the fingerprint recognition touch area on the fingerprint module 2, when the first push rod 427 drives the first shielding plate 428 to move and the second push rod 437 drives the second shielding plate 438 to move, and the first shielding plate 428 and the second shielding plate 438 move closer to each other, the first pressing column 4276 will contact the arc surface of the first convex block 4275. Through the action of the arc surface of the first convex block 4275, the first pressing column 4276 will press the first convex block 4275 downward below the first limiting plate 4274. The first convex block 4275 drives the first lifting rod 4272 to descend. The first lifting rod 4272 drives the first shielding plate 428 to approach the fingerprint module 2 and presses the first cleaning cotton 429 tightly against the fingerprint module 2. At the same time, the second pressing column 4376 will press the second convex block 4375 to press the second cleaning cotton 439 tightly against the fingerprint module 2. By adjusting the first shielding plate 428 and the second shielding plate 438, the first cleaning cotton 429 and the second cleaning cotton 439 can be pressed tightly against the fingerprint module 2, preventing gaps between the first cleaning cotton 429 and the second cleaning cotton 439 and the fingerprint module 2 when the first shielding plate 428 and the second shielding plate 438 block the fingerprint module 2, preventing rainwater or dust from falling on the touch area of the fingerprint module 2 to form water marks and affecting fingerprint recognition, which is beneficial to enhancing the cleaning and protection effect of the first cleaning cotton 429 and the second cleaning cotton 439 on the fingerprint module 2 and enhancing the use effect of the fingerprint module 2.

[0045] The implementation principle of the embodiment of this application is as follows: When fingerprint recognition is required, the buckle 33 is toggled to control the movement of the sliding cover 32, which can quickly open and close the fingerprint touch recognition area of the fingerprint module 2. The sliding cover 32 drives the pushing piece 34 to move until it abuts against the blocking piece 4261. The pushing piece 34 pushes the blocking piece 4261, causing the blocking piece 4261 to drive the first slider 425 to slide on the mounting bracket 41. The first slider 425 drives the first push rod 427 to move towards the sliding cylinder 421. The first push rod 427 drives the first shielding plate 428 to move towards the side of the fingerprint module 2, and during the movement, the touch area of the fingerprint module 2 is wiped by the first cleaning cotton 429, keeping the touch area clean when it is exposed, which is beneficial to enhancing the accuracy of fingerprint reading and recognition for quick recognition. The rotating frame 431 is used to control the linkage of the second push rod 437, enabling the first push rod 427 and the second push rod 437 to move in opposite directions, so that the first shielding plate 428 and the second shielding plate 438 can move away from and approach each other, facilitating the quick exposure of the touch area of the fingerprint module 2 and the quick shielding above the fingerprint module 2 for shielding protection.
