Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery swapping technology, specifically to a battery swapping device for electric vehicles. Background Technology

[0002] Electric bicycles are convenient, time-saving, and labor-saving, and are increasingly becoming the preferred mode of transportation for the public. As a result, electric bicycles have become more widespread, and many shared bicycle companies have also begun to invest in electric bicycles to facilitate people's travel, with a large number of shared bicycles being put on the roads.

[0003] The current announcement number CN214028284U discloses a battery swapping device for electric vehicles, including a main body. A display screen is located at one end of the main body, and a cleaning mechanism is located on the outer side of the display screen. The cleaning mechanism includes a fixing block, a connecting block connected to the inner side of the fixing block, a spiral spring at the connection between the connecting block and the fixing block, and a pull rope movably connected to the surface of the connecting block. A connecting groove is formed on the bottom surface of the fixing block, and one end of the pull rope passes through the connecting groove and is connected to a cleaning block on the outer side of the fixing block. A sponge block is located on one end of the cleaning block. Through this cleaning mechanism, consumers can use the cleaning block to wipe the display screen clean before using the device, avoiding the screen malfunction caused by prolonged exposure to the outside air and environmental factors. Keeping the display screen clean and tidy improves the stability of the device.

[0004] To address the cleaning issue, existing technologies employ cleaning mechanisms to clean the screen. However, this method still presents challenges when removing the battery, as the weight makes it difficult to remove the battery using only the handle, thus reducing the device's usability and making battery removal difficult.

[0030] The present invention will be further described in detail below with reference to embodiments: Example

[0031] like Figure 1-5 As shown, this utility model provides a battery swapping device for electric vehicles, including a swapping cabinet 1. The swapping cabinet 1 has a convenient access unit 2 inside, a fixing unit 3 on the bottom surface of the swapping cabinet 1, a rainproof unit 4 on the top surface of the swapping cabinet 1, and an extension unit 5 inside the rainproof unit 4. The convenient access unit 2 includes a sliding plate 21, which is slidably connected inside the swapping cabinet 1. A fixing rod 22 is slidably connected inside the sliding plate 21. A limit block 23 is fixedly connected to the inner side of the fixing rod 22. A spring 24 is provided on one side of the limit block 23, with one end of the spring 24 fixedly connected inside the swapping cabinet 1 and the other end of the spring 24 fixedly connected to the sliding plate 2. On one side of the battery swapping cabinet 1, a telescopic damping rod 25 is fixedly connected to one side of the sliding plate 21. One end of the telescopic damping rod 25 is fixedly connected to the inside of the battery swapping cabinet 1. By controlling the battery swapping cabinet 1 to open the cabinet door, the battery is placed inside the cabinet 1. At the same time, pushing the battery causes the spring 24 on the back of the sliding plate 21 to retract, which in turn causes the telescopic damping rod 25 to extend. Then, rotating the fixing rod 22 causes the left side of the limiting block 23 to fit against the right side of the sliding plate 21, thus limiting the battery. When the battery is taken out, rotating the fixing rod 22 causes the battery on one side of the sliding plate 21 to pop out through the elastic action of the spring 24, and then the user can take out the battery. Example

[0032] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing unit 3 includes a threaded rod 31, which is threadedly connected to the inside of the battery swapping cabinet 1. A buckle 32 is provided on the inner side of the threaded rod 31. One end of the buckle 32 extends to the bottom side of the battery swapping cabinet 1 and is rotatably connected to an anti-slip fixing block 33. A universal wheel 34 is provided on one side of the anti-slip fixing block 33. One side of the universal wheel 34 is fixedly connected to the bottom surface of the battery swapping cabinet 1. The device is moved to the work location by means of the universal wheel 34. Then, the threaded rod 31 is rotated to make the anti-slip fixing block 33 contact the ground, thereby raising the battery swapping cabinet 1. Then, the threaded rod 31 is clamped by the buckle 32, thereby completing the fixing of the battery swapping cabinet 1. Example

[0033] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the rainproof unit 4 includes a rainproof canopy 41, which is fixedly connected to the top surface of the battery swapping cabinet 1. A motor 42 is fixedly connected to the bottom surface of the rainproof canopy 41. A gear 43 is fixedly sleeved at the output end of the motor 42. A gear 44 is meshed with one side of the gear 43. A threaded rod 45 is fixedly connected to one side of the gear 44. A scraper 46 is threadedly connected to the inner side of the threaded rod 45. The inner side of the scraper 46 is slidably connected to the inside of the rainproof canopy 41. The expansion unit 5 includes a limiting box 51, which is fixedly connected to the bottom surface of the rainproof canopy 41. A motor 52 is fixedly connected to one side of the limiting box 51. A gear 3 53 is fixedly sleeved at the output end. A rack 54 is meshed with one side of the gear 3 53. An extension plate 55 is fixedly connected to one side of the rack 54. The two sides of the extension plate 55 are slidably connected to the inside of the limit box 51. In rainy weather, the rain shelter 41 blocks rainwater. At the same time, when the rainfall is heavy, the motor 2 52 is controlled to drive the gear 3 53 to mesh with the rack 54, thereby driving the extension plate 55 to extend, further protecting the inside of the battery swapping cabinet 1 and preventing rainwater from affecting the use of the battery swapping cabinet 1. At the same time, during long-term use, the motor 1 42 is controlled to drive the gear 1 43 to mesh with the gear 2 44, thereby cleaning the leaves and other impurities on the top surface of the rain shelter 41 through the threaded rod 2 45.

[0034] The working principle of this electric vehicle battery swapping device will be explained in detail below.

[0035] like Figure 1-5As shown, the device is moved to the work location via the casters 34. Then, rotating the threaded rod 31 causes the anti-slip fixing block 33 to contact the ground, raising the battery swapping cabinet 1. The threaded rod 31 is then secured by the buckle 32, thus fixing the battery swapping cabinet 1. The cabinet door is opened by controlling the battery swapping cabinet 1, and the battery is placed inside. Simultaneously, pushing the battery causes the spring 24 on the back of the sliding plate 21 to retract, while simultaneously extending the telescopic damping rod 25. Rotating the fixing rod 22 then causes the left side of the limiting block 23 to adhere to the right side of the sliding plate 21, thus limiting the battery. When removing the battery, the device is rotated... The movable fixing rod 22, through the elastic action of the spring 24, causes the battery on one side of the sliding plate 21 to pop out, allowing the user to retrieve the battery. In rainy weather, the rain shelter 41 blocks rainwater. When the rainfall is heavy, the control motor 2 52 drives the gear 3 53 to mesh with the rack 54, thereby extending the extension plate 55 to further protect the interior of the battery swapping cabinet 1 and prevent rainwater from affecting its use. During long-term use, the control motor 1 42 drives the gear 1 43 to mesh with the gear 2 44, and the threaded rod 2 45 cleans the top surface of the rain shelter 41 of leaves and other impurities.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
