[0021] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 6 As shown, a device locking device in this embodiment includes a device body 1, a roller assembly, a pull rod 5 and a locking mechanism, the roller assembly is rotatably connected to the device body 1, the pull rod 5 is slidably connected to the device body 1, the pull rod 5 can move to a locking position or an unlocking position, and the pull rod 5 is linked to the locking mechanism; when the pull rod 5 is in the locking position, the pull rod 5 performs angular positioning locking on the roller assembly through the locking mechanism; when the pull rod 5 is in the unlocking position, the pull rod 5 causes the locking mechanism to release the angular positioning locking on the roller assembly.

[0023] Preferably, the pull rod 5 is installed on the device body 1 so that it can slide up and down. The pull rod 5 can be retracted into the device body 1 by sliding downward, so as to facilitate storage. At this time, the pull rod 5 after retracting the device body 1 is in a locked position, which can drive the locking mechanism to perform angle positioning and locking on the roller assembly, thereby preventing the roller assembly from rotating, so that the device body 1 can be stably placed on the ground or other places. For example, if the device body 1 is a charging pile device, it can be stably placed on the ground during charging to prevent the movement of the device body 1 from affecting the charging. The pull rod 5 can slide upward to at least partially extend out of the device body 1 as a gripping part for the user. At this time, the pull rod 5 is in an unlocked position, and the roller body can rotate freely, so that the user can pull the device body 1 to move. In short, the device locking device can enable the device body 1 to take into account both the ease of transportation between different locations and the stability and reliability when fixed.

[0024] In this embodiment, the locking mechanism includes a compression spring 35 and a locking pressure rod 34 arranged between the pull rod 5 and the roller assembly; when the pull rod 5 is retracted into the device body 1, the pull rod 5 moves to the locking position, and the end of the locking pressure rod 34 away from the pull rod 5 abuts against the roller assembly to achieve angular positioning locking of the roller assembly; when the pull rod 5 is at least partially extended from the device body 1, the pull rod 5 moves to the unlocking position, and the locking pressure rod 34 is separated from the roller assembly to achieve the release of the angular positioning lock of the roller assembly.

[0025] The compression spring 35 can have a buffering function to reduce the contact impact between the components. After the pull rod 5 moves to the locked position, the compression spring 35 is in a contracted state, and the elastic force of the compression spring 35 and the pressure of the pull rod 5 act on the locking pressure rod 34. The end of the locking pressure rod 34 is in an arc shape and can conform to and fit tightly with the outer wall of the connecting shaft 37, ensuring that the locking pressure rod 34 is tightly against the connecting shaft 37 of the roller assembly, and the friction force prevents the connecting shaft 37 of the roller assembly from rotating relative to the locking pressure rod 34. In addition, when the unlocking and locking mechanism contacts the locking of the pull rod 5, the compression spring 35 can also pop out the pull rod 5, so that the user can pull out the pull rod 5.

[0026] In this embodiment, a guide constraint cavity is provided on the side of the pull rod 5 facing the roller assembly, the compression spring 35 is provided in the guide constraint cavity, and the locking pressure rod 34 is slidably matched with the guide constraint cavity.

[0027] The guide constraint cavity is used to ensure that the movement direction of the locking pressure rod 34 is in the up-down direction to prevent the locking pressure rod 34 from deflecting. Preferably, the top of the locking pressure rod 34 can also be provided with a limiting boss for preventing it from escaping from the guide constraint cavity.

[0028] In this embodiment, a travel limit slot 33 is provided on the device body 1 , and a travel limit slider 36 slidably matched with the travel limit slot 33 is provided on the locking pressure rod 34 .

[0029] The length of the travel limit slot 33 is along the up and down direction, and is used to limit the displacement of the travel limit slider 36 in the up and down direction, thereby limiting the up and down displacement of the locking pressure rod 34, and further limiting the up and down displacement of the pull rod 5. At the same time, when the user holds the pull rod 5 and pulls the device body 1 to move, the pulling force is transmitted to the device body 1 through the pull rod 5, the limiting boss, the locking pressure rod 34, the travel limit slider 36 and the travel limit slot 33, so that the user can pull the device body 1 as a whole to move through the pull rod 5.

[0030] In this embodiment, an unlocking and locking mechanism is also included. A pull rod storage groove 25 and an unlocking and locking slide groove 26 are provided on the device body 1. The unlocking and locking mechanism includes an unlocking and locking button 29 and an unlocking and locking spring 31. The unlocking and locking button 29 is slidably matched with the unlocking and locking slide groove 26. A locking clamp 30 is provided on the unlocking and locking button 29. The two ends of the unlocking and locking spring 31 are respectively connected to the device body 1 and the locking clamp 30; a locking groove 32 is provided on the pull rod 5; when the pull rod 5 is located in the pull rod storage groove 25, the locking clamp 30 is inserted into the locking groove 32, so that the pull rod 5 can be locked in the locked position; by pressing the unlocking and locking button 29, the locking clamp 30 can be separated from the locking groove 32 to release the lock of the pull rod 5.

[0031] The unlocking and locking slot 26 is connected to a telescopic slot 27 and a clamping head slot 28. The locking clamping head 30 slides in the clamping head slot 28. The unlocking and locking button 29 slides in the unlocking and locking slot 26. The telescopic slot 27 is located on the side of the unlocking and locking slot 26 facing the unlocking and locking spring 31, and is used to make way to prevent interference with the unlocking and locking button 29.

[0032] The inside of the pull rod storage slot 25 is connected with an unlocking slot, and the unlocking slot runs forward through the upper side of the front end of the mobile electric pile. The rear end of the unlocking slot is connected with a telescopic slot 27, and the telescopic slot 27 runs through the upper side of the inner wall of the rear end of the pull rod storage slot 25. The upper side of the front end of the telescopic slot 27 is connected with a locking card slot 32, and the locking card slot 32 runs through the upper side of the inner wall of the rear end of the pull rod storage slot 25 and is located on the upper side of the unlocking slot. By unlocking the locking mechanism and locking the pull rod 5 in the locked position, the position of the pull rod 5 can be fixed, and pressure can be continuously provided to the compression spring 35 and the locking pressure rod 34, thereby ensuring the stability and reliability of the device body 1 when placed on the ground or other places. When unlocking, it is only necessary to press the unlocking and locking button 29 to move it toward the direction close to the device body 1 and drive the locking card head 30 to disengage from the locking card slot 32, the compression spring 35 is stretched, and the elastic force of the compression spring 35 can pop out the pull rod 5, so that it is convenient for the user to pull out the pull rod 5.

[0033] In this embodiment, the pull rod 5 is in an inverted "U" shape, and includes a cross beam and two longitudinal beams. The upper ends of the two longitudinal beams are respectively connected to the left and right ends of the cross beam, and the lower ends of the two longitudinal beams are respectively provided with a guide constraint cavity. The compression spring 35, the locking pressure rod 34, the travel limit slot 33 and the travel limit slider 36 are respectively provided with two. Among them, the locking slot 32 is provided in the middle of the cross beam.

[0034] In this embodiment, the roller assembly includes a connecting shaft 37 and two roller bodies 3 respectively arranged at the left and right ends of the connecting shaft 37. The connecting shaft 37 is rotatably connected to the bottom of the device body 1. The two roller bodies 3 rotate coaxially with the connecting shaft 37. The two roller bodies 3 protrude downward from the device body 1. A downwardly protruding support foot 2 is provided at the bottom of the device body 1. The support foot 2 is located on the front side of the device body 1. The pull rod 5 and the roller assembly are located on the rear side of the device body 1.

[0035] When the device body 1 is placed on the ground or other places, the roller body 3 and the support foot 2 that cannot rotate provide support together. When the device body 1 needs to be driven to move, the unlocking and locking button 29 is pressed to move it toward the direction close to the device body 1 and drive the locking card head 30 to disengage from the locking card slot 32, and the compression spring 35 is stretched. The elastic force of the compression spring 35 can pop out the pull rod 5. At this time, the locking mechanism no longer prevents the connecting shaft 37 and the roller body 3 from rotating. The user pulls out the pull rod 5 and tilts the device body 1. The support foot 2 leaves the ground and the two roller bodies 3 are in contact with the ground. The user can easily pull the device body 1 to move.

[0036] like Figure 1-Figure 11 As shown, a mobile charging device in this embodiment includes a device locking device; the device body 1 is a charging pile device with a built-in power distribution mechanism and a power storage mechanism; the device body 1 is provided with a charging head 7, a charging cable 6 and a wire collection box 4, the head end of the charging cable 6 is connected to the power distribution mechanism, the tail end of the charging cable 6 is connected to the charging head 7, the charging cable 6 is wound in the wire collection box 4, and a cleaning wheel 8 for cleaning the charging cable 6 is provided at the outlet of the wire collection box 4.

[0037] The power distribution mechanism can also be equipped with components such as a control panel and a charging interface. The power distribution mechanism, power storage mechanism, control panel and charging interface are all existing technologies and do not belong to the improvement content of this application. Their principles will not be repeated here.

[0038] In order to facilitate the placement of the charging head 7 , a plug interface for installing the charging head 7 can be provided on the device body 1 .

[0039] When in use, the pull rod 5 slides upward to at least partially extend out of the device body 1, serving as the user's gripping part. At this time, the pull rod 5 is in the unlocked position, and the roller body can rotate freely, so that the user can pull the device body 1 to move near the charging port of the car. Then, the pull rod 5 slides downward to retract the device body 1. After the pull rod 5 is retracted, it is in the locked position, which can drive the locking mechanism to lock the roller assembly at an angle, thereby preventing the roller assembly from rotating, so that the device body 1 can be stably placed on the ground or other places, ensuring that it can be stably placed on the ground during charging to prevent the device body 1 from moving. Finally, the user removes the charging head 7 from the plug interface, and pulls the charging head 7 to pull the charging line 6 out of the wire box 4, and then connects the charging head 7 to the charging port of the car for charging, so that the charging location is no longer limited to a specific location, which can improve the convenience and flexibility of car charging. The mobile charging device can also be used as a backup charging power source for long-distance driving. The cleaning wheel 8 can ensure the cleanliness of the charging cable 6, the wire box 4 can prevent the charging cable 6 from being tangled, and the device locking device can make the device body 1 take into account both the ease of movement and the stability and reliability when fixed. Therefore, this embodiment can overcome the defects of traditional charging equipment in terms of charging cable 6 management, cleaning and maintenance, mobility and stability.

[0040] In this embodiment, the device body 1 is provided with a connecting hole 9 corresponding to the position in the wire taking-up box 4, and two annular power-connecting electrode sheets 10 of different diameters are provided in the connecting hole 9; the wire taking-up box 4 is provided with a limiting rotary head 11, a winding rod 12 and a winding baffle 13 connected in sequence, the limiting rotary head 11 is rotatably matched with the connecting hole 9, and the charging line 6 is wound on the winding rod 12; the limiting rotary head 11 is provided with two power-connecting electrode sleeves 16, and the two power-connecting electrode sleeves 16 are respectively provided with power-connecting electrode heads 18, and the two power-connecting electrode heads 18 are respectively connected to the two annular power-connecting electrode sheets 10, and the rotation center axis of the limiting rotary head 11 coincides with the center of the two annular power-connecting electrode sheets 10; the end of the power-connecting electrode head 18 away from the power-connecting electrode sheet is connected to the charging line 6 through a power spring 17.

[0041] The annular power electrode sheet 10 is connected to the power distribution mechanism. By rotating the limit rotary head 11, the winding rod 12 and the winding baffle 13, the charging cable 6 can be stored on the winding rod 12. When the charging cable 6 is pulled out, the limit rotary head 11, the winding rod 12 and the winding baffle 13 can rotate accordingly. During the winding and pulling out of the charging cable 6, the limit rotary head 11 and the power electrode head 18 both rotate. By setting the annular power electrode sheet 10, the power electrode head 18 can always be connected to the annular power electrode sheet 10 and the power distribution mechanism during the rotation process, ensuring the power connection stability of the mobile charging device.

[0042] In this embodiment, a beveled tooth groove 24 is provided at the edge of the winding baffle 13, a wire threading tube 19 is provided at the outlet of the wire taking-up box 4, and a wire ring 23 is provided on the equipment body 1; one end of the cleaning wheel 8 is rotatably connected to the wire ring 23, and the other end of the cleaning wheel 8 is rotatably connected to the wire threading tube 19 through a connecting rotating tube 20, and a beveled gear 21 is provided at the end of the connecting rotating tube 20 away from the cleaning rotation, and the beveled gear 21 is meshed with the beveled tooth groove 24, and the cleaning wheel 8 can be driven to rotate by the rotation of the winding baffle 13.

[0043] In this embodiment, a plurality of cleaning bristles 22 are arranged at intervals inside the cleaning wheel 8, and a through groove structure is provided on the cleaning wheel 8 between two adjacent cleaning bristles 22; the winding baffle 13 is rotatably connected to the wire take-up box 4, and a winding handle 14 is provided on the winding baffle 13, and a handle rotating sleeve 15 is provided on the winding handle 14.

[0044] During the process of pulling out and winding up the charging cable 6, the winding baffle 13 also rotates. At this time, the winding baffle 13 can drive the bevel gear 21 to rotate together through the meshing between the bevel tooth groove 24 and the bevel gear 21. The bevel gear 21 drives the cleaning wheel 8 to rotate between the threading tube 19 and the wire ring 23 through the connecting rotating tube 20. Since the charging cable 6 passes through the cleaning wheel 8 through the connecting rotating tube 20 and the wire ring 23, the multiple cleaning bristles 22 arranged inside the cleaning wheel 8 can rotate and clean the outer wall of the charging cable 6 during the process of pulling out and winding up the charging cable 6, and the dust and debris cleaned can leak out through the through groove structure of the cleaning wheel 8, thereby ensuring the cleanliness of the outer wall of the charging cable 6, preventing dust and debris from eroding the outer wall of the charging cable 6, and preventing dust and debris from entering the wire take-up box 4. Maintaining the cleanliness of the charging cable 6 can reduce the failure rate of the charging cable 6 due to external pollution and extend the service life of the charging cable 6.

[0045] The winding handle 14 and the handle rotating sleeve 15 can facilitate the user to rotate the winding baffle 13 to wind up the charging cable 6 .
