Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1 to 4 As shown, the charging port structure includes a charging port base 100, a charging door (not shown), a drive assembly 200, a plug 300, and a transmission assembly 400. The charging port base 100 has an opening and a charging port 110. The charging door is located in the opening. The drive assembly 200 is located on the charging port base 100 and is connected to the charging door. The plug 300 is connected to the charging port base 100. The transmission assembly 400 is connected to both the drive assembly 200 and the plug 300. The drive assembly 200 can drive the charging door to open and close the opening, and the transmission assembly 400 can drive the plug 300 to open and close the charging port synchronously.

[0032] The charging port structure provided by this utility model is connected to the charging door through the driving component 200 and to the plug 300 through the transmission component 400. The driving component 200 can drive the charging door to open and close, and the transmission component 400 drives the plug to open and close the charging port 110 simultaneously, realizing the automatic opening and closing of the plug 300 and the charging door without manual operation, making it more convenient to use and meeting the needs of automatic charging.

[0033] In one embodiment of this utility model, such as Figure 2 As shown, the charging port base 100 provides a mounting base for components such as the plug 300 and the transmission assembly 400. By integrating multiple components onto the same charging port base 100, the overall structure is simplified, making installation and maintenance more convenient. The charging port 110 includes a first charging port and a second charging port. The plug 300 includes a first plug 320 corresponding to the first charging port and a second plug 330 corresponding to the second charging port. The first charging port and the second charging port are arranged side by side. The first charging port and the second charging port have the same shape but different sizes, wherein the first charging port is... Figure 2 The fast charging port is on the left side, and the second charging port is... Figure 2 The slow charging port is on the right side of the middle.

[0034] In one embodiment of this utility model, such as Figure 6 and Figure 7As shown, the transmission assembly 400 includes a first transmission component 401 and a second transmission component 402. The first end of the first transmission component 401 is connected to the drive assembly, and the second end is connected to the first end cap 320. The first end of the second transmission component 402 is connected to the first end of the first transmission component 401, and the second end is connected to the second end cap 330. Of course, the number of transmission components is not limited to two; it is determined based on the number of charging ports 110. The first transmission component 401 is connected to the second triggering mechanism, and the second transmission component 402 is connected to the first triggering mechanism. By adopting a cross-type mechanical linkage mechanism, linkage is achieved through a purely mechanical structure, avoiding the use of complex electronic control systems, sensors, and actuators. This not only significantly reduces manufacturing costs but also improves the reliability and durability of the system.

[0035] In one embodiment of this utility model, such as Figure 2 and Figure 7 As shown, the drive assembly includes a drive motor 210 and a transmission mechanism. The drive motor 210 is mounted on the charging port base 100. The shaft of the drive motor 210 is connected to the charging door via an arc-shaped connecting rod. The arc-shaped connecting rod can efficiently transmit the driving force to the charging door. The drive motor 210 controls the opening and closing of the charging door by rotating in the forward and reverse directions. The transmission mechanism is connected between the shaft of the drive motor 210 and the first end of the first transmission component 401.

[0036] In one embodiment of this utility model, such as Figure 7 As shown, the transmission mechanism includes a first pulley 220, a second pulley 230, and a drive gear 240. The first pulley 220 is mounted on the shaft of the drive motor 210. The second pulley 230 is connected to the first pulley 220 via a belt. The drive gear 240 is connected to the second pulley 230 and is coaxial with the second pulley 230. The drive gear 240 meshes with the first end of the first transmission component 401.

[0037] In one embodiment of this utility model, a first triggering mechanism is provided for the first charging port, and a second triggering mechanism is provided for the second charging port. The first triggering mechanism and the second triggering mechanism are respectively connected to the transmission assembly 400.

[0038] When the charging gun is inserted into the first charging port, the first triggering mechanism is triggered by the charging gun to drive the second plug 330 to block the corresponding second charging port via the transmission component 400. Specifically, the first triggering mechanism is connected to the second transmission component 402, and the second end of the second transmission component 402 is connected to the second plug 330. When the charging gun is inserted into the first charging port, the charging gun pushes the first triggering mechanism to move, causing the first triggering mechanism to switch from the initial state to the triggered state. The first triggering mechanism drives the second transmission component 402 to move, causing the clutch of the second transmission component 402 to disengage, thereby triggering the second reset component 520 to reset. The second reset component 520 drives the second plug 330 to seal the second charging port. With this setting, the plug 300 automatically identifies the charging gun type and closes the unused side of the charging port 110 to meet the sealing requirements and usage regulations of the charging port 110. By closing the unused side of the charging port 110, the safety and all-weather protection capability of the charging device are enhanced, ensuring the long-term stable operation of the equipment. Similarly, when the charging gun is inserted into the second charging port, the second triggering mechanism is triggered by the charging gun to drive the first plug 320 to seal the corresponding first charging port via the transmission component 400.

[0039] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the charging port structure also includes a housing 600, which is connected to the charging port base 100. The first plug 320, the second plug 330, and the transmission assembly 400 are all housed inside the housing 600. The housing 600 provides a relatively enclosed installation space for the transmission assembly and the plug 300, providing structural support and protection for them, effectively isolating them from the external environment, thus ensuring the normal operation of the transmission mechanism and preventing mechanical failures caused by foreign objects obstructing the connection. The first plug 320 and the second plug 330 are slidably fitted with the housing 600. The housing 600 has an outlet, and the slidable fit between the plug 300 and the housing 600 guides the movement of the plug 300, ensuring its stability and accuracy during extension and retraction, preventing jamming or deflection, and ensuring smooth sealing operations each time. Preferably, the housing 600 has an internal groove, with the first plug 320 and the second plug 330 slidably fitted into the groove. When the first triggering mechanism is triggered by the charging gun, the second cover 330 extends from the outlet to block the corresponding second charging port; when the second triggering mechanism is triggered by the charging gun, the first cover 320 extends from the outlet to block the corresponding first charging port.

[0040] In one embodiment of this utility model, such as Figure 7 and Figure 8 As shown, both the first transmission component 401 and the second transmission component 402 include a first rotating shaft 410, a second rotating shaft 430, and a clutch. One end of the first rotating shaft 410 is configured as the first end of either the first transmission component 401 or the second transmission component 402. Figure 8 The left end of the first rotating shaft 410 located at the top is configured as the first end of the first transmission component 401, and the left end of the first rotating shaft 410 located at the bottom is configured as the first end of the second transmission component 402. The first rotating shaft 410 is arranged perpendicular to the insertion direction of the charging gun, and the first rotating shaft 410 is rotatably connected to the housing 600. Preferably, a support frame is provided inside the housing 600, and the first rotating shaft 410 is rotatably connected to the support frame.

[0041] Two first rotating shafts 410 are arranged parallel and spaced apart. A first transmission component 420 is provided at one end of each first rotating shaft 410. The first transmission component 420 of the first transmission component 401 is connected to the first transmission component 420 of the second transmission component 402. The first transmission component 420 of the first transmission component 401 is connected to the drive assembly. The connection between the first transmission component 420 of the first transmission component 401 and the first transmission component 420 of the second transmission component 402 enables the first rotating shafts 410 of the two transmission components to rotate synchronously. By adopting this synchronous linkage structure, only a single drive assembly 200 is needed to drive the entire device, simplifying the structure of the entire device and reducing production costs.

[0042] One end of the second rotating shaft 430 is configured as the second end of the first transmission component 401 or the second transmission component 402; that is... Figure 8 The right end of the upper second rotating shaft 430 is configured as the second end of the first transmission component 401, and the right end of the lower second rotating shaft 430 is configured as the second end of the second transmission component 402. A second transmission member 450 is provided at one end of the second rotating shaft 430. The second transmission member 450 of the first transmission component 401 is connected to the first plug 320, and the second transmission member 450 of the second transmission component 402 is connected to the second plug 330. The other end of the first rotating shaft 410 is connected to the other end of the second rotating shaft 430 through a clutch.

[0043] In one embodiment of this utility model, the first transmission member 420 includes a first gear. The first gears of the first transmission component 401 and the second transmission component 402 mesh with each other, which can ensure that the two first rotating shafts 410 achieve precise and timely synchronous reverse rotation, thereby ensuring the consistency of the actions of the first plug 320 and the second plug 330 during the opening process. Of course, the specific structural form of the first transmission member 420 is not limited to this, and it can also be implemented by a friction wheel.

[0044] In one embodiment of this utility model, the second transmission component 450 includes a second gear, and both the first cover 320 and the second cover 330 are provided with racks 310 on the side opposite to the charging port 110. The second gears of the first transmission component 401 and the second transmission component 402 mesh with the corresponding racks 310. Figure 8As shown, the second shaft of the first transmission component 401 meshes with the rack 310 of the first plug 320 through a second gear, and the second shaft of the second transmission component 402 meshes with two second gears in sequence, and then meshes with the rack 310 of the second plug 330.

[0045] In one embodiment of this utility model, the charging port structure further includes a first reset member 510 and a second reset member 520. The first reset member 510 is connected between the first plug 320 and the charging port base 100. Of course, the first reset member 510 and the second reset member 520 can also be connected to the housing. The second reset member 520 is connected between the second plug 330 and the charging port base 100. The first reset member 510 is used to drive the plug 300 from the open state to the closed state. By setting the first reset member 510 and the second reset member 520, when the clutch 440 is in the disengaged state, the corresponding plug 300 can be driven from the open state to the closed state. By setting the first reset member 510 and the second reset member 520, when the corresponding clutch 440 is in the disengaged state, an active reset driving force can be provided to the corresponding plug 300, so that it can automatically switch from the open state to the closed state, thereby closing the unused charging port 110.

[0046] When the first triggering mechanism is triggered by the charging gun, the first triggering mechanism drives the clutch of the second transmission component 402 to disengage, so that the second reset component 520 drives the second plug 330 to seal the second charging port.

[0047] Specifically, when the first triggering mechanism is triggered by the charging gun, the first triggering mechanism drives the clutch of the second transmission component 402 to disengage. After the clutch 440 is in the disengaged state, the first rotating shaft 410 is disconnected from the second rotating shaft 430. At this time, the second rotating shaft 430 is no longer restricted by external force and can rotate freely. This triggers the second reset component 520 to reset. The second reset component 520 drives the second cover 330 to move upward, so that the second cover 330 blocks the second charging port. By releasing the restriction on the second reset component 520 corresponding to the second charging port through the clutch 440, the second charging port can be automatically closed by the pre-stored energy second reset component 520, realizing the charging safety interlock function, effectively preventing misoperation, and ensuring the safe operation of the entire charging system.

[0048] When the second triggering mechanism is triggered by the charging gun, the second triggering mechanism drives the clutch of the first transmission component 401 to disengage, so that the first reset component 510 drives the first plug 320 to block the first charging port.

[0049] Specifically, when the second triggering mechanism is triggered by the charging gun, the second triggering mechanism drives the clutch of the first transmission component 401 to disengage. After the clutch 440 is in the disengaged state, the first rotating shaft 410 is disconnected from the second rotating shaft 430. At this time, the second rotating shaft 430 is no longer restricted by external force, which triggers the first reset component 510 to reset. The first reset component 510 drives the first plug 320 to move upward, so that the first plug 320 blocks the first charging port.

[0050] In a preferred embodiment of this utility model, such as Figure 5 As shown, both the first reset element 510 and the second reset element 520 are tension springs. By providing reset power through tension springs, reliable reset power can be provided without external power supply, improving the reliability and fault safety of the device. The tension springs are located at the lower part of the housing 600, and there are two tension springs. The two tension springs correspond one-to-one with the two plugs 300. By configuring an independent reset spring for each plug 300, their independent reset functions are realized, ensuring that the reset action of the other plug 300 is not affected when one charging port 110 is in use. Of course, in order to increase the reset pull force, each plug 300 can also be equipped with two tension springs, which can not only provide a stronger and more reliable reset pull force, but also ensure that the other can still work normally when one tension spring fails, significantly enhancing the durability and safety of the system.

[0051] In one embodiment of this utility model, such as Figure 9 As shown, the clutch 440 includes a first contact 441, a second contact 442, and a compression spring 443. The first contact 441 is sleeved on one end of the first rotating shaft 410. Preferably, the first contact 441 and the first rotating shaft 410 are integrally formed. The second contact 442 is slidably sleeved on the other end of the second rotating shaft 430. The first side of the second contact 442 abuts against the first contact 441. The second contact 442 can move along the length direction of the second rotating shaft 430, thereby moving closer to or away from the first contact 441. The second contact 442 and the second rotating shaft 430 adopt a sliding fit, which can realize the engagement and disengagement of the clutch 440, simplify the structure, and ensure that the actuator can quickly respond to the action of the triggering mechanism. The compression spring 443 is sleeved on the second rotating shaft 430, with one end abutting against the second side of the second contact 442 and the other end abutting against a limiting part provided on the second rotating shaft 430. The limiting part is annular and integrally formed with the second rotating shaft 430.

[0052] When the first triggering mechanism and the second triggering mechanism are in the initial state, the first contact 441 and the second contact 442 are in contact on the first side. At this time, the compression spring 443 is in the first compression state, so that the frictional torque between the first contact 441 and the second contact 442 is greater than the output torque of the first reset member 510 and the second reset member 520. This ensures that when the first plug 320 and the second plug 330 are kept in the open state, the reaction force of the tension spring is insufficient to overcome the static friction of the clutch 440, so that the first plug 320 and the second plug 330 can be reliably locked in the open position to prevent them from closing accidentally. At the same time, the frictional torque between the first contact 441 and the second contact 442 is less than the output torque of the drive assembly 200, ensuring that when the drive assembly 200 drives the unclosed plug 300 to close, the first contact 441 and the second contact 442 corresponding to the closed plug 300 will rotate relative to each other, which will not affect the normal closing of the unclosed plug 300.

[0053] When the first triggering mechanism is triggered by the charging gun, the first contact 441 and the second contact 442 of the second transmission component 402 separate; specifically, when the first triggering mechanism is triggered by the charging gun, the first contact 441 and the second contact 442 separate, and at this time, the second contact 442, pushed by the first triggering mechanism, moves towards the limiting part (i.e., Figure 8 (In the direction indicated by the middle arrow A) the compression spring 443 is in the second compression state, and the compression spring 443 is further compressed, and the first rotating shaft 410 is disconnected from the second rotating shaft 430.

[0054] When the second triggering mechanism is triggered by the charging gun, the first contact 441 of the first transmission component 401 separates from the second contact 442. The situation where the second triggering mechanism is triggered by the charging gun is the same as that where the first triggering mechanism is triggered by the charging gun, and will not be described in detail here.

[0055] It should be noted that the first contact 441 and the second contact 442 can achieve synchronous rotation through friction surfaces, or synchronous rotation can be achieved by setting positioning protrusions on the end faces and coupling them with positioning holes.

[0056] In one embodiment of the present invention, the frictional torque between the first contact 441 and the second contact 442 is greater than the output torque of the first reset member 510 and the second reset member 520, and the frictional torque between the first contact 441 and the second contact 442 is less than the output torque of the drive assembly 200.

[0057] In one embodiment of this utility model, such as Figure 8As shown, both the first and second triggering mechanisms include a pressing connector 121 and a transmission rod 122. A sliding groove is provided on the charging port base 100 or the housing 600, and the pressing connector 121 is slidably engaged within the sliding groove to achieve a sliding fit between the pressing connector 121 and the charging port base 100 or the housing 600. The transmission rod 122 is arranged along the length of the first rotating shaft 410 and is slidably engaged with the housing 600. The first end of the transmission rod 122 abuts against the first side of the second contact member 442, and the second end of the transmission rod 122 is provided with a first guide slope 123, which is slidably engaged with the pressing connector 121.

[0058] When the first triggering mechanism is triggered by the charging gun, the pressing connector 121 of the first triggering mechanism pushes the first contact 441 of the second transmission component 402 to separate from the second contact 442 via the transmission rod 122.

[0059] When the charging gun is inserted into the first charging port, the charging gun triggers the first trigger mechanism, pressing the connector 121 along the insertion direction of the charging gun. Figure 8 Slide the middle arrow B in the direction of the sliding, pressing the connector 121 to push the transmission rod 122 along the length direction of the first rotating shaft 410 via the first guide slope 123. Figure 8 Move in the direction indicated by the middle arrow A to cause the transmission rod 122 to push the first contact 441 to separate from the second contact 442.

[0060] When the second triggering mechanism is triggered by the charging gun, the pressing connector 121 of the second triggering mechanism pushes the first contact 441 of the first transmission component 401 and the second contact 442 apart via the transmission rod 122. Since the triggering principle of the second triggering mechanism is the same as that of the first triggering mechanism, it will not be described in detail here.

[0061] In one embodiment of this utility model, such as Figure 8 As shown, a second guide slope is provided on the side of the pressing connector 121 facing the first guide slope 123. The second guide slope and the first guide slope 123 are slidably engaged. By adopting this wedge-shaped mechanism design with double slope engagement, a stable and linear contact surface can be formed, making the entire sliding process smoother and without jamming, greatly reducing wear, and improving the durability and operational stability of the entire trigger mechanism 120. In addition, when the charging gun is pulled out, the sliding engagement of the second guide slope and the first guide slope 123 ensures that the pressing connector 121 can return to its initial position.

[0062] In one embodiment of this utility model, the plug 300 is disposed on the side of the charging port base 100 opposite to the side where the charging gun is inserted. That is, the plug 300 is disposed on the side of the charging port base 100 opposite to the user when the user inserts the charging gun. By hiding these moving parts behind the user's line of sight and operating path, damage to the mechanism due to accidental contact during the insertion and removal of the charging gun can be effectively prevented, thereby greatly improving safety. At the same time, placing the plug 300 in a non-visible position on the charging port base 100 makes the overall appearance of the charging port base 100 complete and aesthetically pleasing.

[0063] The working principle of the charging port structure: When the drive motor 210 rotates, the shaft of the drive motor 210 drives the charging door to open via the arc-shaped connecting rod. At the same time, the drive motor 210 drives the first pulley 220 to rotate, the first pulley 220 drives the second pulley 230 to rotate via the belt, the second pulley 230 drives the drive gear 240 to rotate, and the drive gear 240 drives the first gear to rotate. Since the two first gears are meshed, the two first shafts 410 rotate synchronously. The two first shafts 410 drive the corresponding second shafts 430 to rotate via the clutch 440, and the two second shafts 430 drive the second gears to rotate. The second gears drive the corresponding first caps 320 to open via the rack 310. At this time, both tension springs are stretched.

[0064] When the charging gun is inserted into the first charging port, the charging gun triggers the first trigger mechanism, pressing the connector 121 along the insertion direction of the charging gun. Figure 8 Slide the middle arrow B in the direction of the sliding, pressing the connector 121 to push the transmission rod 122 along the length direction of the first rotating shaft 410 via the first guide slope 123. Figure 8 The transmission rod 122 moves in the direction indicated by the middle arrow A, causing the transmission rod 122 to push the first contact 441 and the second contact 442 to separate, and the first rotating shaft 410 of the second transmission component 402 to disconnect from the second rotating shaft 430; at this time, the second rotating shaft 430 is no longer restricted by external force and can rotate freely, and the second reset component 520 drives the second plug 330 to seal the second charging port; similarly, the principle of inserting the charging gun into the second charging port is the same as described above, and will not be described in detail here.

[0065] When charging is complete and the first charging port needs to be closed, the drive motor 210 rotates in the opposite direction, sequentially driving the first rotating shaft 410 and the second rotating shaft 430 to rotate in the opposite direction, so that the first cover 320 seals the first charging port, and the charging door closes under the drive of the drive motor 210. During this process, since the second cover 330 of the second charging port has been closed in place, the second cover 330 cannot move, which causes the first contact 441 and the second contact 442 of the second transmission component 402 to slide relative to each other.

[0066] This utility model also provides a vehicle, which includes the charging port structure described in any of the above embodiments.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
