[0040] The specific embodiments of the utility model will be further illustrated below in combination with the drawings.

[0041] It is easy to understand that according to the technical scheme of the utility model, the general technical personnel in the art can replace the various structural modes and implementation modes of each other without changing the essential spirit of the utility model. Therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the utility model.

[0042] In the present specification, the orientation terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or possibly mentioned are defined with respect to the structure shown in the drawings, and they are relative concepts, so they may change accordingly according to their different positions, different use states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0043] In some embodiments of the utility model, such as Figures 1-4As shown, the lifting type charging gun includes a base 1, a lifting assembly 2, a charging head 3, a protective cover 4 and a motor 5, the lifting assembly 2 is installed on the base 1, the motor 5 drives the lifting assembly 2 to move the charging head 3 up and down, the protective cover 4 is used for covering above the charging head 3, further comprising a linkage assembly, a first drive gear 6 and a second drive gear 7, the linkage assembly further comprises a protective cover linkage unit 8 and a lifting linkage unit 9, the protective cover linkage unit 8 is connected with the protective cover 4, the lifting linkage unit 9 is connected with the lifting assembly 2, the driving shaft 51 of the motor 5 is connected with the first drive gear 6 and the second drive gear 7 and synchronously drives them;

[0044] When the first drive gear 6 rotates to be connected with the protective cover linkage unit 8, the protective cover linkage unit 8 drives the protective cover 4 to open or close, and at the same time, the second drive gear 7 is not connected with the lifting linkage unit 9;

[0045] When the first drive gear 6 rotates to be not connected with the protective cover linkage unit 8, the second drive gear 7 is connected with the lifting linkage unit 9, and the lifting linkage unit 9 drives the lifting assembly 2 to extend or retract.

[0046] Specifically, as shown in the figure, Figure 1 The lifting type charging gun is in a closed state, the protective cover 4 covers on the base 1, and the lifting assembly 2 and the charging head 3 are retracted to the inside of the base 1. The protective cover 4 can protect the charging head 3 and prevent rainwater from entering.

[0047] As shown in the figure, Figure 2 The motor 5 and the lifting assembly 2 are installed on the base 1. In the closed state, the motor 5 does not work, and the lifting assembly 2 is also retracted to the shortest length.

[0048] As shown in the figure, Figure 3 The protective cover linkage unit 8 and the lifting linkage unit 9 are also installed on the base 1. The first drive gear 6 and the second drive gear 7 are fixedly connected on the driving shaft 51 of the motor 5. In the closed state, the first drive gear 6 is in the connected state with the protective cover linkage unit 8, and is prepared to drive the protective cover 4 to open. At this time, the second drive gear 7 is not connected with the lifting linkage unit 9.

[0049] As shown in the figure, Figure 4 The lifting type charging gun is in an open cover state, and at this time, the protective cover 4 is opened to expose the charging head 3.

[0050] As shown in the figure, Figure 5 In the open cover state, the motor 5 rotates forward to drive the protective cover linkage unit 8 to drive the two protective covers 4 to move in opposite directions.

[0051] As shown in the figure, Figure 6As shown, motor 5 rotates forward, driving the first drive gear 6 and the second drive gear 7 to rotate. Since the first drive gear 6 is connected to the protective cover linkage unit 8, the first drive gear 6 drives the protective cover linkage unit 8, which in turn drives the protective cover 4 to open. At this time, the second drive gear 7 also rotates synchronously, but it does not rotate to a position where it is not connected to the lifting linkage unit 9, and therefore does not drive the lifting linkage unit 9 to move.

[0052] like Figure 9 As shown, motor 5 continues to rotate forward. When the first drive gear 6 separates from the protective cover linkage unit 8 and the second drive gear 7 connects to the lifting linkage unit 9, the protective cover 4 remains open. The lifting linkage unit 9 then begins to drive the lifting assembly 2 upward, which in turn causes the charging head 3 to rise.

[0053] like Figure 7 As shown, the charging head 3 rises upwards and moves toward the charging seat on the vehicle body to begin charging.

[0054] After charging is complete, motor 5 rotates in the reverse direction, and the second drive gear 7 connects to the lifting linkage unit 9. The second drive gear 7 drives the lifting linkage unit 9, which in turn drives the lifting assembly 2 to move downwards. The lifting assembly 2 then drives the charging head 3 to retract into the base 1. Subsequently, the second drive gear 7 rotates to disengage from the lifting linkage unit 9, and the first drive gear 6 rotates to connect with the protective cover linkage unit 8. The protective cover linkage unit 8 drives the two protective covers 4 to move closer to each other, thus closing the protective covers 4 and returning them to their original positions. Figure 1 The location.

[0055] In this embodiment, a single motor drives the opening and closing of the protective cover and the raising and lowering of the charging head, saving on motor costs. Furthermore, by simply controlling the forward and reverse rotation of the motor, the series of actions of opening and closing the protective cover and raising and lowering the charging head can be displayed, simplifying the control process.

[0056] Furthermore, such as Figure 3 As shown, the protective cover linkage unit 8 includes a first driven wheel 81, a first transmission wheel 82 and a first connecting rod 83, and the first drive gear 6 is a half gear;

[0057] When the first drive gear 6 rotates to mesh with the first driven wheel 81, the first driven wheel 81 drives the first transmission wheel 82 to rotate, the first transmission wheel 82 drives the first connecting rod 83, and the first connecting rod 83 drives the protective cover 4 to open or close.

[0058] Specifically, such as Figure 3As shown, in the closed state of the protective cover 4, the first drive gear 6 is just engaged with the first driven gear 81. The first driven gear 81 is always engaged with the first transmission gear 82, the first transmission gear 82 is rotatably connected with one end of the first connecting rod 83, and the other end of the first connecting rod 83 is rotatably connected with the protective cover 4.

[0059] As shown, when the motor 5 rotates forward, the motor 5 drives the first drive gear 6 to rotate, the first drive gear 6 drives the first transmission gear 82 to rotate, the first transmission gear 82 drives the first connecting rod 83, and the first connecting rod 83 swings from inside to outside, thereby driving the upper protective cover 4 to open outward. Figure 6

[0060] As shown, when the motor 5 rotates forward, the motor 5 drives the first drive gear 6 to rotate, the first drive gear 6 drives the first transmission gear 82 to rotate, the first transmission gear 82 drives the first connecting rod 83, and the first connecting rod 83 swings from inside to outside, thereby driving the upper protective cover 4 to open outward.

[0061] Further, as shown, the protective cover 4 includes two half covers, each half cover is connected with a set of protective cover linkage units 8 on both sides, and the two first driven gears 81 on the same side of the two half covers are connected by a first belt 84. The first drive gear 6 has two, respectively connected with the first driven gear 81 on both sides of one of the half covers. Figures 5-6

[0062] Specifically, the protective cover linkage unit 8 has two sets, and the left and right ends of the motor 5 each extend a drive shaft 51, and each drive shaft 51 is provided with a first drive gear 6 and a second drive gear 7. The first drive gear 6 also has two, respectively corresponding to a set of protective cover linkage units 8. Each set of protective cover linkage units 8 includes two first driven gears 81, two first transmission gears 82, two first connecting rods 83 and a first belt 84, and the first belt 84 connects the two first driven gears 81.

[0063] When the motor 5 rotates forward, it simultaneously drives the two first drive gears 6 to rotate, the first drive gear 6 drives the first driven gear 81 engaged with it to rotate, and synchronously drives the other first driven gear 81 to rotate through the first belt 84. The two first connecting rods 83 on the same set of protective cover linkage units 8 swing away from each other, thereby driving the two protective covers 4 to open outward.

[0064] Further, as shown, the lifting linkage unit 9 includes a second driven gear 91, a second transmission gear 92 and a second connecting rod 93, and the second drive gear 7 is a half gear. Figures 8-9

[0065] ​​​When the second drive gear 7 rotates to mesh with the second driven wheel 91, the first drive gear 6 disengages from the first driven wheel 81. The second driven wheel 91 drives the second transmission wheel 92 to rotate, and the second transmission wheel 92 drives the second connecting rod 93. The second connecting rod 93 drives the lifting assembly 2 to extend or retract.

[0066] Specifically, such as Figure 9 As shown, there are two sets of lifting linkage units 9, with each of the two second drive gears 7 corresponding to one set of lifting linkage units 9. Each set of lifting linkage units 9 includes two second driven wheels 91, two second transmission wheels 92, two second connecting rods 93, and a second belt 94, with the second belt 94 connecting the two second driven wheels 91.

[0067] When the first drive gear 6 disengages from the first driven wheel 81, the second drive gear 7 rotates to mesh with the second driven wheel 91, and the two second drive gears 7 simultaneously drive the two sets of lifting linkage units 9 to move.

[0068] like Figure 8 As shown, the four second connecting rods 93 extend upwards, simultaneously causing the lifting assembly 2 to extend upwards, and the lifting assembly 2 causes the charging head 3 to rise vertically upwards.

[0069] Since the second drive gear 7 is also a half gear, when the first drive gear 6 meshes with the first driven wheel 81, the second drive gear 7 disengages from the second driven wheel 91; when the first drive gear 6 rotates to the point of disengagement from the first driven wheel 81, the second drive gear 7 rotates to the position of meshing with the second driven wheel 91. This allows for the operation of first opening the protective cover 4, and then raising the charging head 3. When the motor 5 rotates in the reverse direction, it first drives the charging head 3 downwards back into the base 1, and then drives the protective cover 4 to close.

[0070] Furthermore, such as Figure 9 As shown, the first drive gear 6 and the second drive gear 7 are coaxially mounted, with the first drive gear 6 closer to the outside and the second drive gear 7 closer to the inside. The first belt 84 and the second belt 94 are arranged in parallel, making the overall structure more compact and preventing interference between the first connecting rod 83 and the second connecting rod 93.

[0071] Furthermore, such as Figure 8 As shown, the second link 93 includes two folding rods. When the lifting assembly 2 retracts, the folding rods fold to the upper surface of the base 1. When the second link 93 is driven to unfold, the second link 93 unfolds upward and pushes the lifting assembly 2 to extend upward.

[0072] Furthermore, such as Figure 8As shown, the lifting assembly 2 includes a lifting platform 21, a lifting slider 22, and a lifting rail 23. The charging head 3 is installed on the upper surface of the lifting platform 21. The lifting slider 22 is connected to the bottom of the lifting platform 21 and can slide up and down along the lifting rail 23.

[0073] Specifically, the upper end of the second connecting rod 93 is connected to the lower surface of the lifting platform 21, and the lower end of the second connecting rod 93 is connected to the second transmission wheel 92. When the second connecting rod 93 extends, it drives the lifting platform 21 to rise, and the lifting slider 22 moves upward with the lifting platform 21. The lifting slide rail 23 is mounted on the base 1.

[0074] The lifting assembly 2 provides more stable support for the charging head 3, and the second link 93 provides the power source for the lifting of the charging head 3.

[0075] Furthermore, such as Figure 4 As shown, the base 1 includes a base plate 11 and a surrounding plate 12. The surrounding plate 12 is arranged around the base plate 11, and an opening is left on the top of the surrounding plate 12. A protective cover 4 is placed on the top of the surrounding plate 12, and the opening is exposed when the protective cover 4 is opened.

[0076] Furthermore, such as Figure 4 As shown, the top surface of the enclosure 12 has a movable groove 121. The protective cover linkage unit 8 passes through the movable groove 121 and is connected to the protective cover 4, and can move in the movable groove 121.

[0077] Furthermore, such as Figure 4 As shown, the enclosure 12 is also provided with a lifting groove 122, and at least part of the structure of the lifting assembly 2 can extend and retract along the lifting groove 122.

[0078] Specifically, the lifting slide rail 23 is installed in the lifting groove 122, and the lifting slide rail 23 can move up and down along the lifting groove 122.

[0079] like Figure 7 As shown, when the lifting slider 22 slides out to its maximum stroke relative to the lifting slide rail 23, the lifting slider 22 drives the lifting slide rail 23 to continue to move up and down relative to the lifting groove 122, thereby increasing the maximum stroke of the lifting assembly 2.

[0080] When the charging head 3 descends, the lifting slider 22 moves downward relative to the lifting slide rail 23. When the lifting slider 22 and the lifting slide rail 23 are completely overlapped, the lifting slide rail 23 slides downward relative to the lifting groove 122.

[0081] In this invention, a single motor drives the opening and closing of the protective cover and the raising and lowering of the charging head, saving on motor costs. Furthermore, by simply controlling the forward and reverse rotation of the motor, the series of actions of opening and closing the protective cover and raising and lowering the charging head can be displayed, simplifying the control process.

[0082] The above merely describes the principles and preferred embodiments of the present application. It should be noted that, for those skilled in the art, on the basis of the principles of the present application, a number of other variants can also be made, and should also be considered within the protection scope of the present application.
