[0002] At present, there are many ways to charge electric vehicles, such as configuring one charging pile for one parking space, but this method is relatively expensive and requires a dedicated parking space for adaptation. In Chinese Patent Publication No.: CN105162218B, a safe charging station for electric vehicles with high charging gun utilization and low cost is disclosed. The charging station of the present invention is composed of two or more mechanical storage devices suspending a corresponding number of charging circuits; a charging circuit is composed of a charging gun and a charging cable, and the charging circuit is connected to the distribution cabinet; the mechanical storage device includes: a high-mounted hanging rail and a tension spring balancer; wherein, two or more sliding hanging wheels are installed on the high-mounted hanging rail, and the sliding hanging wheel close to the charging gun side is connected to the tension spring balancer, and the tension spring balancer is connected to the charging gun or connected to the charging cable connected to the charging gun, and the sliding hanging wheel close to the distribution cabinet side is connected to the charging cable.

[0003] Although the above-mentioned charging station can realize charging at multiple different parking spaces with one charging station, its power cord still has a great safety hazard due to the telescopic pulling method. Utility Model Content

[0004] Therefore, in view of the above-mentioned problems, the present invention proposes a mobile charging device, which solves the technical problem that the power cord of the existing charging station is pulled by telescopic means, which poses a potential safety hazard.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mobile charging device, including a transverse walking track, a plurality of main seat bodies that can move along the transverse walking track, a plurality of longitudinal resident tracks, and a power track, each longitudinal resident track is close to or connected to the transverse walking track, each main seat body can enter the longitudinal resident track from the transverse walking track, a power sub-terminal is provided on the main seat body, and a power female terminal is provided on the power track corresponding to each resident track. When the main seat body moves along the longitudinal resident track, the power sub-terminal can be inserted into the corresponding power female terminal to realize electrical connection, a charging gun is connected to the main seat body through a power cord, and the power cord is electrically connected to the power sub-terminal.

[0006] Furthermore, a winding disc is disposed on the main seat body, and a winding driving device for driving the winding disc to rotate is disposed on the main seat body.

[0007] Furthermore, the winding drive device is a servo motor, and the winding disc body includes a connecting shaft connected to the main shaft of the winding drive device, a supporting ring body connected to the connecting shaft, and a plurality of winding columns arranged on the circumference of the supporting ring body, and the lower end of each winding column is bent outward to form a supporting foot.

[0008] Furthermore, a pressure sensor for sensing the pressure between the power sub-terminal and the power female terminal is arranged on the power sub-terminal and / or the power female terminal.

[0009] Furthermore, a pushing mechanism for separating the power sub-end from the power female end is provided on the power rail at the power female end, and the pushing mechanism includes a pushing cylinder and a pushing plate provided on the piston rod of the pushing cylinder.

[0010] Furthermore, the power sub-end or the power female end is provided with a locking device for realizing a tight connection between the power sub-end and the power female end.

[0011] Furthermore, the locking device includes a locking threaded sleeve arranged on the power supply sub-end, a threaded section arranged on the power supply female end, and a rotation driving device that drives the locking threaded sleeve to move toward the power supply female end and rotate.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] 1. This device can realize the movement of the main seat body on the transverse track to realize the conversion of different parking spaces through the setting of the main seat body, transverse travel track, longitudinal residence track, and power track. The setting of the longitudinal residence track can realize the avoidance of the transverse travel track during charging to avoid occupying the transverse travel track during charging. The setting of the power track can make the main seat body only realize electrical connection when charging is needed after entering the longitudinal residence track. The power track can be closed, with only the female end of the power supply exposed to connect with the sub-end of the power supply. This can greatly improve the safety performance of charging.

[0014] 2. The setting of the winding reel and the winding drive device can realize the automatic lowering and folding of the charging gun. In this way, the horizontal walking track, the longitudinal resident track, the power track, and the main seat can be placed at a high place in places such as garages. The charging gun is lowered only when charging is needed, thereby realizing the rational use of space and ensuring the safety of the equipment.

[0015] 3. The setting of the winding reel can effectively realize the effective winding of the power cord and achieve fast and stable retraction and release.

[0016] 4. The setting of the pressure sensor can realize the induction of the connection between the power sub-end and the power female end, thereby ensuring a tight connection between the power sub-end and the power female end.

[0017] 5. When the power supply sub-end and the power supply female end need to be separated after charging, it is difficult to separate them due to the tight connection, which requires a large driving force from the main seat. However, this method will increase power consumption. Therefore, a push-out mechanism is added to assist in separating the power supply sub-end and the power supply female end, thereby reducing the power consumption of the main seat, and the separation method of the push-out mechanism is more stable.

[0018] 6. The locking device is set to achieve the tight connection between the power sub-end and the power female end. After the main seat pushes the power sub-end and the power female end to be tightly connected, there is no need to increase the driving force, which is also to reduce power consumption and increase the connection effect.

[0019] 7. The locking device adopts a locking thread sleeve, a thread section, and a rotary drive device, and its structure is relatively simple and has a good locking effect. Of course, the locking device can also adopt other structures, such as a buckle structure, an electromagnetic adsorption structure, etc. BRIEF DESCRIPTION OF THE DRAWINGS

Each longitudinal resident track 3 is close to or connected to the transverse travel track 1, and each main seat body 2 can enter the longitudinal resident track 3 from the transverse travel track 1. A power sub-terminal 21 is provided on the main seat body 2, and a power female terminal 41 is provided on the power track 4 corresponding to each resident track. When the main seat body 2 travels along the longitudinal resident track 3, the power sub-terminal 21 can be inserted into the corresponding power female terminal 41 to achieve electrical connection. A charging gun 23 is connected to the main seat body 2 through a power cord 22, and the power cord is electrically connected to the power sub-terminal 21. Baffles are provided on both sides of the transverse travel track 1 to prevent the main seat body 2 from sliding off. Similarly, baffles are also provided on both sides of the longitudinal resident track 3 to prevent the main seat body 2 from sliding off. The baffles are not marked in the figure, and can be referred to Figure 2 The filling pattern portion in the figure is a schematic cross-section of the baffle.

[0029] The main seat body 2 is provided with a winding disc body, and the main seat body 2 is provided with a winding driving device (not shown in the figure, which is located inside the main seat body) for driving the winding disc body to rotate. The winding driving device is a servo motor, and the winding disc body includes a connecting shaft 241 connected to the main shaft of the winding driving device, a supporting ring body 242 connected to the connecting shaft 241, and a plurality of winding columns 243 arranged on the circumference of the supporting ring body 242, and the lower end of each winding column 243 is bent outward to form a supporting foot 244.

[0030] The power sub-terminal 21 and / or the power female terminal 41 are provided with a pressure sensor 411 for sensing the pressure between the power sub-terminal 21 and the power female terminal 41. In this solution, the pressure sensor 411 is provided on the power female terminal 41.

[0031] The power rail 4 is provided with a push-out mechanism for separating the power sub-terminal 21 from the power female end 41 at the power female end 41, and the push-out mechanism includes a push-out cylinder 42 and a push plate 43 provided on the piston rod of the push-out cylinder 42. The power sub-terminal and / or the power female end are provided with a magnetic attraction structure for achieving adsorption between the power sub-terminal and the power female end. When the value of the pressure sensor meets the standard value, the power sub-terminal 21 and the power female end 41 are magnetically adsorbed through the magnetic attraction structure. The magnetic attraction structure is a magnetic ring 412 provided on the power female end, and the magnetic ring 412 is located on the inner side of the pressure sensor 411. The magnetic ring 412 is coated with a polyvinyl chloride layer 413 except for a side close to the power sub-terminal 21.

[0032] The power sub-end 21 or the power female end 41 is provided with a locking device for realizing a tight connection between the power sub-end 21 and the power female end 41. The locking device comprises a locking threaded sleeve 51 provided on the power sub-end 21, a threaded section 52 provided on the power female end 41, and a rotation driving device 53 for driving the locking threaded sleeve 51 to move toward the power female end 41 and rotate, and a driving screw head 531 is provided on the free end of the rotation driving device 53, and the driving screw head 531 cooperates with the outer surface of the locking nut sleeve 51 to realize rotation driving and pushing.

[0033] A charging method applied to the above mobile charging device comprises the following steps:

[0034] In the first step, the main seat body moves along the horizontal walking track and then enters the longitudinal resident track, thereby realizing the plugging of the power supply sub-end and the power supply female end, setting the standard value of the pressure until the value of the pressure sensor is 120% to 150% of the standard value, and then the main seat body reduces the driving force to realize the value of the pressure sensor is 95% to 105% of the standard value;

[0035] In the second step, the rotary drive device on the power supply sub-end is started to realize the threaded matching between the locking threaded sleeve on the power supply sub-end and the threaded section on the power supply female end, and then the power of the main seat body disappears and remains stationary;

[0036] In the third step, the winding drive device on the main seat body is started to release the charging gun, and the user can use the charging gun to charge.

[0037] After charging is completed, the user unplugs the charging gun. When the recycling instruction is received, the winding drive device starts to rewind the charging gun, and then the main seat body starts to realize that the value of the pressure sensor is 110% to 120% of the standard value, and then the rotation drive device starts to realize the disengagement of the locking thread sleeve and the thread segment, and then the ejection mechanism starts to realize that the push plate pushes the power sub-end to disengage from the power female end, and then the main seat body moves out of the longitudinal residence track and enters the transverse walking track, and then returns to the initial position or enters the next longitudinal residence track.

[0038] By controlling the plugging of the power sub-end and the power female end, a better plug-in connection can be achieved. When the value of the pressure sensor is 120% to 150% of the standard value, it can be ensured that the plugging is too tight, that is, the degree of plugging is sufficient. Then it is reduced to 95% to 105% to ensure the thread matching of the locking thread sleeve on the power sub-end and the thread segment on the power female end. After charging is completed, the value of the pressure sensor is 110% to 120% of the standard value, in order to achieve the convenience of disengagement of the locking thread sleeve and the thread segment and prevent the increase of friction. Then the ejection mechanism is used to assist the disengagement of the power sub-end and the power female end, so as to achieve a better disengagement purpose.

[0039] The power sub-end, power female end, and charging gun in the above scheme are all conventional components in this field, which can be selected according to actual needs. The above winding drive device and rotation drive device are servo motors, which are conventional technologies in this field. The walking structure of the above main seat body is a conventional technical means in this field, and reference can be made to the horizontal and vertical walking vehicle disclosed in Chinese Patent Application No.: CN201420201181.X, or a special chassis with optional vertical and horizontal walking disclosed in Chinese Patent Application No.: CN201510029380.6.

[0040] By adopting the above technical solution, the beneficial effects of the present invention are:

[0041] 1. This device can realize the movement of the main seat body on the transverse track to realize the conversion of different parking spaces through the setting of the main seat body, transverse walking track, longitudinal resident track, and power track. The setting of the longitudinal resident track can realize the avoidance of the transverse walking track during charging, so as to avoid occupying the transverse walking track during charging. The setting of the power track can make the main seat body electrically connected only when it enters the longitudinal resident track and needs to be charged. The power track can be closed, with only the power female end exposed to connect with the power sub-end. This can greatly improve the safety performance of charging. The setting of the pressure sensor can realize the induction of the connection between the power sub-end and the power female end, thereby ensuring a tight connection between the power sub-end and the power female end.

[0042] 2. The setting of the winding reel and winding drive device can realize the automatic lowering and retracting of the charging gun, so that the horizontal walking track, longitudinal resident track, power track and main seat can be placed at a high place in the garage and other places. Only when charging is needed, the charging gun is lowered, so as to realize the rational use of space and ensure the safety of the equipment. The setting of the winding reel can effectively realize the effective winding of the power cord and realize quick and stable retraction and release.

[0043] 3. When the power supply sub-end and the power supply female end need to be separated after charging, it is difficult to separate them due to the tight connection, which requires a large driving force from the main seat. However, this method will increase power consumption. Therefore, a push-out mechanism is added to assist in separating the power supply sub-end and the power supply female end, thereby reducing the power consumption of the main seat, and the separation method of the push-out mechanism is more stable.

[0044] 4. The setting of the locking device realizes the tight connection between the power sub-end and the power female end. After the main seat pushes the power sub-end and the power female end to connect tightly, there is no need to increase the driving force, which is also to reduce power consumption and increase the connection effect. The locking device adopts a locking threaded sleeve, a threaded section, and a rotating drive device. Its structure is relatively simple and has a good locking effect. Of course, the locking device can also adopt other structures, such as a snap-on structure, an electromagnetic adsorption structure, etc.

[0045] 5. The setting of magnetic attraction structure can assist in the connection between the power supply sub-end and the power supply female end, and the purpose is still to make the connection between the power supply sub-end and the power supply female end tighter. The setting of polyvinyl chloride layer can effectively avoid interference with the pressure sensor, and make the magnetic lines of force concentrated on the side close to the power supply sub-end, thereby enhancing the magnetic attraction effect.
