[0032] Reference Figure 1 , showing a schematic diagram of a locking component locking a clamping component in a charging device for a vehicle provided in an embodiment of the present application; referring to Figure 2 , showing a schematic diagram of a locking component in a charging device for a vehicle provided in an embodiment of the present application releasing the locking of a clamping component; referring to Figure 3 , showing a schematic diagram of a fixing cylinder provided in an embodiment of the present application; referring to Figure 4 , showing Figure 1 A partial enlarged view of the middle part; refer to Figure 5 , shows a schematic diagram of a sliding column connected to a lever provided in an embodiment of the present application and embedded in a guide groove on a guide frame. Figures 1 to 5 As shown, the charging device for the vehicle comprises: a charging plug 10 and a clamping assembly 20 , wherein the clamping assembly 20 is used for being installed at a charging interface 200 on a body 100 of the vehicle.

[0033] The outer wall of the charging plug 10 is connected with a moving component 30, and the moving component 30 is movable along the axial direction of the charging plug 10. The outer wall of the charging plug 10 is movably connected with a locking component 40, and the locking component 40 is connected to the moving component 30. The moving component 30 is used to drive the locking component 40 to rotate relative to the outer wall of the charging plug 10 so that the locking component 40 switches between the first position and the second position; when the charging plug 10 is plugged into the charging interface 200 on the vehicle body 100, the locking component 40 is opposite to the snap-on component 20. When the moving component 30 slides along the first direction, the moving component 30 drives the locking component 40 to move to the first position, and the locking component 40 abuts against the snap-on component 20 to lock the charging plug 10; when the moving component 30 slides along the second direction, the moving component 30 drives the locking component 40 to move to the second position, and the locking component 40 is separated from the snap-on component 20 to release the lock of the charging plug 10. The first direction is opposite to the second direction.

[0034] In the embodiment of the present application, since the outer wall of the charging plug 10 is connected to the moving component 30, and the moving component 30 is movable along the axial direction of the charging plug 10, and the outer wall of the charging plug 10 is movably connected to the locking component 40, once the moving component 30 moves along the axial direction of the plug, the moving component 30 can drive the locking component 40 to move, so that the locking component 40 will rotate relative to the outer wall of the charging plug 10. During the rotation of the locking component 40, the locking component 40 can switch between the first position and the second position. The clamping assembly 20 is used to be installed at the charging interface 200 on the vehicle body 100. Therefore, once the clamping assembly 20 is installed at the charging interface 200 on the vehicle body 100, when the charging plug 10 is plugged into the charging interface 200 on the vehicle body 100 to charge the vehicle body 100, the moving assembly 30 can slide along the first direction, so that the moving assembly 30 drives the locking assembly 40 to rotate relative to the outer wall of the charging plug 10, so that the charging plug 10 moves to the first position, and the locking assembly 40 is easy to abut against the clamping assembly 20, thereby locking the assembly 40. The charging plug 10 is locked and fixed to prevent the charging plug 10 from being easily detached from the charging interface 200. After the charging of the vehicle body 100 is completed, the moving component 30 can slide along the second direction, so that the moving component 30 drives the locking component 40 to rotate relative to the outer wall of the charging plug 10 again, so that the locking component 40 moves to the second position, and the locking component 40 is separated from the clamping component 20. The locking component 40 releases the lock on the charging plug 10, and the charging plug 10 can be separated from the charging interface 200 on the vehicle body 100. That is, in the embodiment of the present application, by providing a moving component 30 and a locking component 40 on the outer wall of the charging plug 10, and the clamping component 20 is used to be installed at the charging interface 200 on the vehicle body 100, when the vehicle body 100 is charged, once the charging plug 10 is inserted into the charging interface 200, the moving component 30 can be moved, driving the locking component 40 to rotate relative to the charging plug 10, so that the locking component 40 abuts against the clamping component 20 to lock the charging plug 10, thereby preventing the charging plug 10 from being easily separated from the charging interface 200, that is, during the process of charging the vehicle body 100, the charging plug 10 is prone to fall off, thereby avoiding the problem of charging failure or poor charging of the vehicle body 100. That is, the charging device provided in the embodiment of the present application can improve the safety of charging the vehicle body 100 and the charging efficiency of charging the vehicle body 100.

[0035] It should be noted that, in the embodiment of the present application, the charging plug 10 may be a charging plug 10 on a charging gun for charging the vehicle body 100 , and the charging plug 10 may be connected to a charging cable, which is connected to a charging pile.

[0036] In addition, in some embodiments, the moving assembly 30 may include a screw barrel 31, which is connected to the locking assembly 40, the outer wall of the charging plug 10 is sleeved with the fixed barrel 11, and the outer wall of the fixed barrel 11 is provided with an external thread, the inner wall of the screw barrel 31 is provided with an internal thread, the screw barrel 31 is sleeved on the fixed barrel 11, and the screw barrel 31 and the fixed barrel 11 are threadedly connected through external threads and internal threads; when the screw barrel 31 is rotated, the screw barrel 31 is movable relative to the fixed barrel 11, so that the locking assembly 40 switches between the first position and the second position.

[0037] Since the screwing barrel 31 is connected to the locking assembly 40, the outer wall of the charging plug 10 is sleeved with the fixing barrel 11, and the outer wall of the fixing barrel 11 is provided with an external thread, and the inner wall of the screwing barrel 31 is provided with an internal thread. The screwing barrel 31 is sleeved on the fixing barrel 11, and the screwing barrel 31 and the fixing barrel 11 are threadedly connected through the external thread and the internal thread. Therefore, when the screwing barrel 31 is rotated, the screwing barrel 31 can move relative to the fixing barrel 11 due to the threaded connection between the screwing barrel 31 and the external threaded tube, which is equivalent to making the screwing barrel 31 move on the fixing barrel 11, so that the screwing barrel 31 can drive the locking assembly 40 to rotate relative to the outer wall of the charging plug 10, so that the locking assembly 40 can switch between the first position and the second position. Specifically, when the screw barrel 31 is rotated along the first rotation direction, the screw barrel 31 can move along the first direction, so that the screw barrel 31 drives the lock to move to the first position, so that the locking assembly 40 abuts against the clamping assembly 20 that has been installed on the vehicle body 100, and the locking assembly 40 can fix the charging plug 10. When the lock abuts against the clamping assembly 20, the clamping assembly 20 can apply a reaction force to the locking assembly 40, and the locking assembly 40 applies the reaction force to the screw barrel 31. However, the threaded connection between the screw barrel 31 and the fixing barrel 11 can prevent the screw barrel 31 from moving, so that after the locking assembly 40 moves to the first position, once the screw barrel 31 is stopped, the screw barrel 31 will be stationary and will not move along the second direction, so that the locking assembly 40 can continue to lock the charging plug 10. When the screw barrel 31 is screwed in the second rotation direction, the screw barrel 31 moves in the second direction, so that the screw barrel 31 drives the locking assembly 40 to move to the second position, the locking assembly 40 is separated from the clamping assembly 20, and the locking assembly 40 releases the fixing of the charging plug 10. That is, by providing the screw barrel 31 and connecting the screw barrel 31 with the locking assembly 40, the locking assembly 40 can be easily switched between the first position and the second position.

[0038] The first rotation direction is opposite to the second rotation direction. For example, the first rotation direction is clockwise, and the second rotation direction is counterclockwise.

[0039] It should be noted that the fixing cylinder 11 can be welded to the outer wall of the charging plug 10, so that the fixing cylinder 11 is fixed to the outer wall of the charging plug 10. Of course, the fixing cylinder 11 can also be fixed to the outer wall of the charging plug 10 in other ways, for example, an interference fit between the charging plug 10 and the fixing cylinder 11. The embodiment of the present application does not limit the way in which the fixing cylinder 11 is fixed to the charging plug 10.

[0040] In addition, in the embodiment of the present application, an external thread may be directly provided on the outer wall of the charging plug 10 , and the screw barrel 31 may be directly sleeved on the outer wall of the charging plug 10 , so that when the screw barrel 31 is rotated, the screw barrel 31 moves relative to the charging plug 10 .

[0041] In addition, in the embodiment of the present application, when the fixing cylinder 11 is sleeved on the outer wall of the charging plug 10, the locking assembly 40 can be movably connected to the outer wall of the fixing cylinder 11, so that the locking assembly 40 can move relative to the charging plug 10. When the outer wall of the charging plug 10 is provided with an external thread, the locking assembly 40 can be directly movably connected to the outer wall of the charging plug 10.

[0042] In addition, in some embodiments, one end of the screw barrel 31 can be connected to a guide member 311, and a guide groove 312 is provided on the guide member 311. Part of the locking assembly 40 is embedded in the guide groove 312 and is movable relative to the guide groove 312. The guide groove 312 is used to guide the locking assembly 40 when the locking assembly 40 switches between the first position and the second position.

[0043] Since one end of the screw barrel 31 is connected to a guide member 311, a guide groove 312 is provided on the guide member 311, and part of the locking assembly 40 is embedded in the guide groove 312 and is movable relative to the guide groove 312, once the screw barrel 31 is rotated to move the screw barrel 31 along the outer wall of the fixed barrel 11, the screw barrel 31 can drive the guide member 311 to move, so that the guide member 311 can apply force to the locking assembly 40, so that the locking assembly 40 moves in the guide groove 312, so that the guide groove 312 guides the locking assembly 40, and facilitates the switching of the locking assembly 40 between the first position and the second position. That is, by embedding part of the locking assembly 40 in the guide groove 312 on the guide member 311, when the screw barrel 31 is rotated, the locking assembly 40 can be easily switched between the first position and the second position.

[0044] In addition, in the embodiment of the present application, one end of the screw barrel 31 can also be directly connected to the locking assembly 40, which is equivalent to one end of the screw barrel 31 not being connected to the guide member 311 but being directly connected to the locking assembly 40. This embodiment of the present application does not limit this.

[0045] In addition, in some embodiments, the moving assembly 30 may further include a sliding cylinder 32, which is sleeved on the fixed cylinder 11 and can slide relative to the fixed cylinder 11. The first end of the sliding cylinder 32 is connected to one end of the screwing cylinder 31, and the second end of the sliding cylinder 32 is connected to the locking assembly 40. When the screwing cylinder 31 is rotated, the screwing cylinder 31 is movable relative to the fixed cylinder 11, so that the sliding cylinder 32 moves axially along the fixed cylinder 11 to drive the locking assembly 40 to switch between the first position and the second position.

[0046] Since the sliding cylinder 32 is sleeved on the fixed cylinder 11 and the sliding cylinder 32 is slidable relative to the fixed cylinder 11, the first end of the sliding cylinder 32 is connected to one end of the screwing cylinder 31, and the second end of the sliding cylinder 32 is connected to the locking assembly 40. Therefore, when the screwing cylinder 31 is rotated, the screwing cylinder 31 can move relative to the fixed cylinder 11, so that the screwing cylinder 31 drives the sliding cylinder 32 to slide along the outer wall of the fixed cylinder 11, and the sliding cylinder 32 drives the locking assembly 40 to rotate relative to the charging plug 10, so that the locking assembly 40 switches between the first position and the second position, so that the locking assembly 40 can abut against the clamping assembly 20 to lock the charging plug 10, or the locking assembly 40 is separated from the clamping assembly 20 to release the lock on the charging plug 10. That is, by providing the sliding cylinder 32, it can be further facilitated that when the screwing cylinder 31 rotates, the locking assembly 40 switches between the first position and the second position.

[0047] In addition, in the embodiment of the present application, the first end of the sliding cylinder 32 is connected to one end of the screwing cylinder 31 in the following manner: the first end of the sliding cylinder 32 may be provided with a clamping groove 321, one end of the screwing cylinder 31 is fixed with a clamping boss 313, and the clamping boss 313 is embedded in the clamping groove 321, so that the first end of the sliding cylinder 32 is connected to one end of the screwing cylinder 31. Through such a setting, when it is necessary to connect the first end of the sliding cylinder 32 to one end of the screwing cylinder 31, the clamping boss 313 can be embedded in the clamping groove 321 by the bracket, so as to realize the connection between the sliding cylinder 32 and the screwing cylinder 31, that is, through such a setting, it is convenient to connect the sliding cylinder 32 to the screwing cylinder 31.

[0048] Of course, the first end of the sliding cylinder 32 can be connected to one end of the screwing cylinder 31 in other ways, for example, a slot is provided at one end of the screwing cylinder 31, and a clamping platform is provided at the first end of the sliding cylinder 32, and the clamping platform is embedded in the slot. The specific way in which the first end of the sliding cylinder 32 is connected to one end of the screwing cylinder 31 is not limited in the embodiment of the present application.

[0049] In addition, in some embodiments, a first slide groove 111 may be provided on the outer wall of the fixed cylinder 11, and the first slide groove 111 extends along the axial direction of the fixed cylinder 11, and a first sliding platform 322 is provided on the inner wall of the sliding cylinder 32, and the first sliding platform 322 is embedded in the first slide groove 111; or, a second sliding platform is provided on the outer wall of the fixed cylinder 11, and a second slide groove is provided on the inner wall of the sliding cylinder 32, and the second slide groove extends along the axial direction of the sliding cylinder 32, and the second sliding platform is embedded in the second slide groove.

[0050] Since the first slide groove 111 can be provided on the outer wall of the fixed cylinder 11, and the first slide platform 322 is provided on the inner wall of the sliding cylinder 32, and the first slide platform 322 is embedded in the first slide groove 111, once the screwing tube is rotated, the screwing tube moves, so that the screwing tube can apply force to the sliding cylinder 32, and the first slide platform 322 can slide in the first slide groove 111, so that the sliding cylinder 32 can move relative to the fixed cylinder 11. That is, by providing the first slide groove 111 and the first slide platform 322, it is easy to realize that the sliding cylinder 32 slides relative to the fixed cylinder 11.

[0051] It should be noted that the number of the first slide grooves 111 can be set according to actual needs, wherein when the number of the first slide grooves 111 is multiple, the multiple first slide grooves 111 can be spaced apart along the circumferential direction of the fixed cylinder 11. For example, the number of the first slide grooves 111 is 5, and the 5 first slide grooves 111 are spaced apart along the circumferential direction of the fixed cylinder 11. In addition, the number of the first sliding platforms 322 can be equal to the number of the first slide grooves 111.

[0052] In addition, since the outer wall of the fixed cylinder 11 is provided with a second sliding platform and the inner wall of the sliding cylinder 32 is provided with a second sliding groove, once the screwing tube is rotated, the screwing tube moves, so that the screwing tube can apply force to the sliding cylinder 32, and the second sliding platform can slide in the second sliding groove, so that the sliding cylinder 32 can move relative to the fixed cylinder 11. That is, by providing the second sliding groove and the second sliding platform, it is easy to realize the sliding of the sliding cylinder 32 relative to the fixed cylinder 11.

[0053] It should be noted that the number of the second chute can be set according to actual needs, wherein when the number of the second chute is multiple, the multiple second chute can be spaced apart along the circumferential direction of the fixed cylinder 11. For example, the number of the second chute is 5, and the 5 second chute are spaced apart along the circumferential direction of the fixed cylinder 11. In addition, the number of the second sliding tables can be equal to the number of the second chute.

[0054] In addition, in some embodiments, the movable component 30 may also include a sliding cylinder 32, which is sleeved on the fixed cylinder 11 and can slide relative to the fixed cylinder 11, the first end of the sliding cylinder 32 is connected to one end of the screwing cylinder 31, the second end of the sliding cylinder 32 is connected to a guide member 311, and a guide groove 312 is provided on the guide member 311, and a part of the locking component 40 is embedded in the guide groove 312 and can move relative to the guide groove 312.

[0055] By such a configuration, when the screw tube is rotated, the screw tube can move along the axial direction of the fixed tube 11, so that the screw tube can drive the sliding tube 32 to slide, and the sliding tube 32 can drive the guide member 311 to move, and the guide member 311 can apply force to the locking assembly 40, so that the locking assembly 40 rotates relative to the charging plug 10, so that the locking assembly 40 switches between the first position and the second position. That is, by such a configuration, when the screw tube is rotated, the locking assembly 40 can switch between the first position and the second position, so that the locking assembly 40 locks the charging plug 10, or unlocks the locking assembly 40.

[0056] In addition, in the embodiment of the present application, the guide member 311 can be directly connected to the screw tube. Of course, the guide member 311 can also be connected to the sliding cylinder 32, and the sliding cylinder 32 is connected to the screw tube.

[0057] In addition, in some embodiments, the locking assembly 40 may include a lever 41 and a sliding column 42, the sliding column 42 is fixed to the outer wall of the first end of the lever 41, and the sliding column 42 is connected to the moving assembly 30, and the middle part of the lever 41 is movably connected to the outer wall of the charging plug 10; when the moving assembly 30 slides along the first direction, the moving assembly 30 drives the lever 41 to move to the first position, and the second end of the lever 41 abuts against the clamping assembly 20 to lock the charging plug 10; when the moving assembly 30 slides along the second direction, the moving assembly 30 drives the lever 41 to move to the second position, and the second end of the lever 41 is separated from the clamping assembly 20 to release the lock on the charging plug 10.

[0058] Since the sliding column 42 is fixed to the outer wall of the first end of the lever 41, and the sliding column 42 is connected to the moving assembly 30, the middle part of the lever 41 is movably connected to the outer wall of the charging plug 10. Therefore, once the moving assembly 30 moves relative to the outer wall of the charging plug 10, the moving assembly 30 can drive the sliding column 42 to move, thereby causing the lever 41 to rotate relative to the outer wall of the charging plug 10, and the lever 41 moves to the first position or the second position. Specifically, when the moving component 30 slides along the first direction, the moving component 30 drives the lever 41 to move to the first position, and the second end of the lever 41 abuts against the clamping component 20, so that the lever 41 can lock the charging plug 10 to prevent the charging plug 10 from being separated from the charging interface 200, so that the charging plug 10 can charge the vehicle body 100 more safely; when the moving component 30 slides along the second direction, the moving component 30 drives the lever 41 to move to the second position, and the second end of the lever 41 separates from the clamping component 20, so that the lever 41 can unlock the charging plug 10, so that the charging plug 10 can be separated from the charging interface 200, thereby facilitating the separation of the charging plug 10 from the charging interface 200 after the charging of the vehicle body 100 is completed.

[0059] Of course, the locking assembly 40 may also be of other types, for example, the locking assembly 40 is a locking frame, and the locking frame is connected to the sliding column 42. The specific type of the locking assembly 40 is not limited in the embodiment of the present application.

[0060] In addition, in the embodiment of the present application, when the moving assembly 30 includes a screwing tube, the screwing tube is connected to the sliding cylinder 32, and the sliding cylinder 32 is connected to the guide member 311, the sliding column 42 can be embedded in the guide groove 312, so that when the screwing tube 31 is rotated, the screwing tube 31 drives the sliding cylinder 32 to slide, and the sliding cylinder 32 drives the guide member 311 to move, so that the sliding column 42 can move in the guide groove 312, and then the lever 41 can rotate relative to the outer wall of the charging plug 10. Specifically, as Figure 1 As shown, when the screw tube is rotated to move the screw tube in the first direction, the screw tube drives the sliding cylinder 32 to move in the first direction, so that the sliding cylinder 32 drives the guide member 311 to move, so that the sliding column 42 moves in the guide groove 312, so that the lever 41 rotates to the first position, the lever 41 abuts against the clamping assembly 20, and the lever 41 can lock the charging plug 10; Figure 2 As shown, when the screw tube is rotated to move along the second direction, the screw tube drives the sliding cylinder 32 to move along the second direction, so that the sliding cylinder 32 drives the guide member 311 to move, so that the sliding column 42 moves in the guide groove 312, so that the lever 41 rotates to the second position, the lever 41 is separated from the clamping assembly 20, and the lever 41 can release the lock on the charging plug 10.

[0061] In addition, in some embodiments, a connecting member 50 is fixed to the outer wall of the charging plug 10, and the connecting member 50 includes a first fixed arm 51 and a second fixed arm 52. The first end of the first fixed arm 51 is fixedly connected to the outer wall of the charging plug 10, the second end of the first fixed arm 51 is fixedly connected to the first end of the second fixed arm 52, the second end of the second fixed arm 52 is movably connected to the middle part of the lever 41, and there is an angle between the first fixed arm 51 and the second fixed arm 52.

[0062] Through such a configuration, the second fixed arm 52 can ensure that the lever 41 does not contact the outer wall of the charging plug 10 during its movement. When a fixing cylinder 11 is provided on the outer wall of the charging plug 10, it can ensure that the lever 41 does not contact the fixing cylinder 11, thereby facilitating the rotation of the lever 41, so that the lever 41 locks the charging plug 10 or unlocks the charging plug 10.

[0063] It should be noted that the middle portion of the lever 41 can be connected to the second end of the second fixed arm 52 via a rotating shaft, so that the lever 41 can rotate relative to the second fixed arm 52 , that is, the lever 41 can move relative to the second fixed arm 52 .

[0064] In addition, in the embodiment of the present application, the angle between the first fixed arm 51 and the second fixed arm 52 can be set according to actual needs, for example, the angle between the first fixed arm 51 and the second fixed arm 52 is 120 degrees, and for another example, the angle between the first fixed arm 51 and the second fixed arm 52 is 135 degrees. This embodiment of the present application is not limited here.

[0065] In addition, in the embodiment of the present application, the snap-on assembly 20 may be an annular structure, that is, the snap-on assembly 20 is equivalent to a snap-on ring. In this case, the snap-on ring may be fixed to the charging interface 200 on the vehicle body 100, and the lever 41 may be in contact with or separated from the snap-on ring.

[0066] In the embodiment of the present application, since the outer wall of the charging plug 10 is connected to the moving component 30, and the moving component 30 is movable along the axial direction of the charging plug 10, and the outer wall of the charging plug 10 is movably connected to the locking component 40, once the moving component 30 moves along the axial direction of the plug, the moving component 30 can drive the locking component 40 to move, so that the locking component 40 will rotate relative to the outer wall of the charging plug 10. During the rotation of the locking component 40, the locking component 40 can switch between the first position and the second position. The clamping assembly 20 is used to be installed at the charging interface 200 on the vehicle body 100. Therefore, once the clamping assembly 20 is installed at the charging interface 200 on the vehicle body 100, when the charging plug 10 is plugged into the charging interface 200 on the vehicle body 100 to charge the vehicle body 100, the moving assembly 30 can slide along the first direction, so that the moving assembly 30 drives the locking assembly 40 to rotate relative to the outer wall of the charging plug 10, so that the charging plug 10 moves to the first position, and the locking assembly 40 is easy to abut against the clamping assembly 20, thereby locking the assembly 40. The charging plug 10 is locked and fixed to prevent the charging plug 10 from being easily detached from the charging interface 200. After the charging of the vehicle body 100 is completed, the moving component 30 can slide along the second direction, so that the moving component 30 drives the locking component 40 to rotate relative to the outer wall of the charging plug 10 again, so that the locking component 40 moves to the second position, and the locking component 40 is separated from the clamping component 20. The locking component 40 releases the lock on the charging plug 10, and the charging plug 10 can be separated from the charging interface 200 on the vehicle body 100. That is, in the embodiment of the present application, by providing a moving component 30 and a locking component 40 on the outer wall of the charging plug 10, and the clamping component 20 is used to be installed at the charging interface 200 on the vehicle body 100, when the vehicle body 100 is charged, once the charging plug 10 is inserted into the charging interface 200, the moving component 30 can be moved, driving the locking component 40 to rotate relative to the charging plug 10, so that the locking component 40 abuts against the clamping component 20 to lock the charging plug 10, thereby preventing the charging plug 10 from being easily separated from the charging interface 200, that is, during the process of charging the vehicle body 100, the charging plug 10 is prone to fall off, thereby avoiding the problem of charging failure or poor charging of the vehicle body 100. That is, the charging device provided in the embodiment of the present application can improve the safety of charging the vehicle body 100 and the charging efficiency of charging the vehicle body 100.

[0067] An embodiment of the present application provides a vehicle, which includes a vehicle body 100 and a charging device for a vehicle according to any one of the first aspects described above.

[0068] The vehicle body 100 has a charging interface 200 , and a charging slot 110 is disposed at the charging interface 200 .
