Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a novel charging port cover assembly for new energy electric vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the charging system, as one of the core components of new energy vehicles, is receiving increasing attention for its ease of use and safety. The charging port cover, as a key protective component of the charging system, must be reliably opened during charging to expose the charging port, and must be closed after charging is complete to prevent the entry of foreign objects, rainwater, etc., while also avoiding accidental opening during driving that could lead to component damage or safety risks.

[0003] Currently, most new energy vehicle charging port cover assemblies on the market adopt a simple hinge connection structure, lacking an effective opening and closing control mechanism. Specifically, when the cover is opened, it relies solely on the frictional resistance of the hinge itself to maintain the open state. When subjected to slight external forces (such as wind, vehicle vibration, or accidental contact), the cover is prone to automatically closing and impacting the charging gun, potentially interrupting the charging process. Users must manually adjust the cover to continue charging, which is extremely inconvenient. When closed, the cover is only fixed by a simple buckle structure. If the buckle loosens when the vehicle is bumpy or subjected to external force, the cover will open unexpectedly, affecting the vehicle's appearance and potentially exposing the charging port to harsh environments, shortening the component's lifespan, and even posing safety hazards. Utility Model Content

[0004] This utility model provides a novel charging port cover assembly for new energy electric vehicles, which overcomes the shortcomings of the prior art and adopts the following technical solution:

[0005] A novel charging port cover assembly for new energy electric vehicles includes a charging base, a cover, a locking structure, and a hinge structure connecting the charging base and the cover. The charging base has a recessed upper surface with a downward-facing groove for accommodating the cover, and a charging port is provided within the groove. The cover is shaped to fit the groove and can be closed or opened by rotation. The locking structure is installed between the cover and the charging base, and its opening and closing action confines the cover within the groove or allows it to detach from the groove. The hinge structure includes a movable flap fixed to the cover and a fixed component to the bottom wall of the groove. A fixed page plate is provided, wherein the movable page plate and the fixed page plate are hinged together by a pin to form a rotating shaft, and the movable page plate can rotate around the rotating shaft with the cover; at least one end of the rotating shaft has a V-shaped torsion spring, the first torsion arm of the torsion spring is connected to the movable page plate, and the second torsion arm is limited and installed on the fixed page plate; when the cover rotates from the open position to the closed position, the torsion spring deforms with the movement of the movable page plate and generates elastic resistance to prevent the cover from rotating in the closing direction; when the cover rotates from the closed position to the open position, the torsion spring deforms with the movement of the movable page plate and generates elastic resistance to prevent the cover from rotating in the opening direction.

[0006] Preferably, a torsion spring is provided at each of the left and right ends of the rotating shaft, the two torsion springs are arranged opposite each other and the second torsion arms of both are located on the fixed plate.

[0007] Preferably, the two torsion springs are arranged opposite each other on the fixed plate.

[0008] Preferably, the torsion spring rotates synchronously with the movable page plate on the fixed page plate with the second torsion arm as the rotation axis. When the cover is opened, the torsion spring is inclined relative to the bottom wall of the cavity. When the cover is closed, the torsion spring is flat relative to the bottom wall of the cavity.

[0009] Preferably, the second torsion arm includes a transition arm located outside the fixed page plate and a connecting arm that is limited and mounted on the fixed page plate; the transition arm and the connecting arm are integrally formed, the transition arm is connected to the first torsion arm, and the connecting arm is limited and mounted on the fixed page plate by a limiting structure and can rotate.

[0010] Preferably, the connecting arm is configured as a connecting shaft, and the two connecting shafts on the fixed page are arranged opposite each other, with their axes coinciding.

[0011] Preferably, the limiting structure includes a screw, a nut, and an anti-detachment washer located between the two. The anti-detachment washer is disposed on the fixed plate, and its side skirt extending upward relative to the fixed plate has a cavity for accommodating the connecting arm. The connecting arm is located in the cavity. The screw passes through the fixed plate, and the bottom wall of the cavity cooperates with the nut to lock the anti-detachment washer to the fixed plate. The head of the screw at least partially covers the cavity to prevent the connecting arm from detaching from the cavity.

[0012] Preferably, the limiting structure is configured as a guide sleeve, which is fixed to the fixed page plate and its axis is parallel to the length direction of the fixed page plate; the connecting arm is inserted into the guide sleeve and is limited, and can rotate within the guide sleeve.

[0013] Preferably, the bottom wall of the charging socket cavity has an annular guide portion formed around the charging port. The guide portion extends upward perpendicularly to the bottom wall of the cavity, and its top end is lower than the upper surface of the charging socket.

[0014] Preferably, the movable plate extends to form side wing holes on both sides, and the first torsion arm is inserted into the side wing holes and abuts against them. The extension direction of the side wing holes is the same as the axial direction of the rotation shaft.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] (1) This utility model provides a novel charging port cover assembly for new energy electric vehicles, which effectively solves the problem that existing charging port covers for new energy vehicles are easily affected by external forces and accidentally open or close when in the open or closed state. Through the design of the V-shaped torsion spring, targeted elastic resistance is generated during the opening and closing of the cover, which effectively prevents the cover from being accidentally opened or closed, ensuring the safety of the charging port. The overall structure is simple, and the core function is achieved through the cooperation of the hinge structure and the torsion spring, which is easy to manufacture and assemble.

[0017] (2) Two torsion springs are placed opposite each other on both sides of the rotating shaft to ensure that the moving plate is subjected to balanced force when it rotates, avoiding the cap from tilting, lifting or local wear caused by a single torsion spring, thus significantly improving structural stability and service life.

[0018] (3) The two torsion springs are set opposite each other, which enhances the elastic symmetry and synergistic effect applied to both sides of the movable plate. In this way, the lateral forces generated by the torsion springs on both sides can cancel each other out, further improving the structural stability. At the same time, the abutting design ensures that the torsion springs are subjected to force and rotate synchronously during deformation, making the resistance output more uniform.

[0019] (4) The torsion spring is rotated around the second torsion arm. The tilted posture when it is open and the flat posture when it is closed ensures that the movement trajectory of the torsion spring matches the rotation of the cover and avoids structural interference. The switching between tilted and flat postures can adapt to the space requirements under different conditions, reduce friction with the surrounding parts of the charging port cover assembly, and extend the service life of the torsion spring.

[0020] (5) The guide section can guide the charging gun to quickly align with the charging port, improving the convenience of charging operation; secondly, the design of the height being lower than the upper surface of the charging base can not only prevent the cover from closing, but also guide the water in the cavity to drain to the edge, avoiding rainwater accumulation in the charging port and damaging the charging components, thus taking into account both practicality and waterproofness.

[0037] Please see Figures 1 to 8 .

[0038] This embodiment provides a novel charging port cover assembly for new energy electric vehicles, including a charging base 1, a cover 2, a locking structure, and a hinge structure connecting the charging base 1 and the cover 2. This assembly utilizes the elastic deformation characteristics of a V-shaped torsion spring 5 to generate targeted elastic resistance during the opening and closing of the cover 2, effectively solving the problem of existing charging port covers being easily opened and closed accidentally by external forces, thus improving safety and convenience. This embodiment mainly includes a charging base 1, a cover 2, a locking structure, and a hinge structure connecting the charging base 1 and the cover 2; wherein,

[0039] Charging station 1 is part of the vehicle body (or fixed to the vehicle body), see [link / reference]. Figures 1 to 3 The upper end of the cavity is recessed downwards to form a cavity 11 for accommodating the cover 2. The shape of the cavity 11 is adapted to the outline of the cover 2 (which adopts a rectangular or circular design). A charging port 12 is provided at the bottom of the cavity 11, which is used to cooperate with the charging gun to achieve charging. An annular guide portion 13 is integrally formed on the periphery of the charging port 12. The guide portion 13 extends upwards perpendicular to the bottom wall of the cavity 11, and the top height is lower than the upper end surface of the charging base 1. In this embodiment, the guide portion 13 can guide the charging gun to quickly align with the charging port 12 during charging, reducing the alignment operation time. Secondly, when it rains or the car is washed, the water accumulated in the cavity 11 can be guided to the edge of the cavity 11 to drain out. That is, the guide portion 13 can block rainwater and prevent water from seeping into the charging port 12 and damaging the electrical components.

[0040] The cover 2 is made of metal and its shape is perfectly matched to the cavity 11 of the charging base 1. It can be rotated through the hinge structure to completely cover the cavity 11 or completely expose the charging port 12.

[0041] Locking structure, see Figure 2 and Figure 3 It is installed between the cover 2 and the charging base 1, and through the opening and closing action, the cover 2 is confined within the cavity 11 or can be disengaged from the cavity 11. The locking structure in this embodiment is an existing rotary switch structure. The locking structure includes a lock cylinder 31 and a lock seat 32 that cooperate with each other. The lock cylinder 31 is fixedly installed on the inner side of the cover 2, and the lock seat 32 is fixedly installed on the charging base 1. The lock seat 32 is offset relative to the charging port 12 to prevent obstruction of the charging gun from being inserted into the plug-in port. The lock cylinder 31 is provided with a turning groove for key insertion. When the cover 2 needs to close the cavity 11, the key (not shown) is inserted and the lock cylinder 31 is turned clockwise, so that the lock cylinder 31 rotates and locks itself with the lock seat 32, and the cover 2 is confined within the cavity 11. The key is turned counterclockwise, which drives the lock cylinder 31 to rotate and disengage from the lock seat 32. At this time, the cover 2 can be disengaged from the cavity 11 by rotation. The locking structure is installed in a position that avoids the hinge structure, so as not to affect the opening and closing of the cover 2.

[0042] Hinged structure, see Figure 4It includes a movable leaf plate 41, a fixed leaf plate 42, and a pin 43, all of which are metal structural components. The movable leaf plate 41 and the fixed leaf plate 42 are hinged together by the pin 43 to form a rotating shaft. The movable leaf plate 41 can rotate around the rotating shaft with the cover 2. Specifically, one end of the movable leaf plate 41 is fixed to the inner edge of the cover 2 by welding, and the other end has a shaft hole for the pin 43 to pass through. The fixed leaf plate 42 is fixed to the bottom wall of the cavity 11 by screws 61, and its end has a shaft hole that is offset from the shaft hole of the movable leaf plate 41. The pin 43 passes through the shaft holes of the movable leaf plate 41 and the fixed leaf plate 42 in sequence, and the two are hinged to form a rotating shaft, so that the movable leaf plate 41 and the cover 2 can rotate flexibly around the pin 43.

[0043] In this embodiment, see Figures 4 to 6 At least one end of the rotating shaft has a V-shaped torsion spring 5. The torsion spring 5 is made of spring steel and has good elastic recovery performance. The first torsion arm 51 of the torsion spring 5 is connected to the movable leaf plate 41, and the second torsion arm 52 is limited and installed on the fixed leaf plate 42. Specifically, in this embodiment, there are two torsion springs 5. One torsion spring 5 is provided on each of the left and right ends of the rotating shaft (pin 43). The two torsion springs 5 ​​are arranged opposite each other (the V-shaped openings face each other), and the second torsion arms 52 of both are located on the fixed leaf plate 42 and are abutted against each other. Side wing holes are formed on both sides of the movable leaf plate 41. The extension direction of the side wing holes is the same as the axial direction of the rotating shaft (pin 43). The side wing holes are used to insert the first torsion arm 51 of the torsion spring 5 and form an abutting connection.

[0044] When the cover 2 rotates from the open position to the closed position, the torsion spring 5 deforms with the movement of the movable leaf plate 41 and generates elastic resistance to prevent the cover 2 from rotating in the closed direction; when the cover 2 rotates from the closed position to the open position, the torsion spring 5 deforms with the movement of the movable leaf plate 41 and generates elastic resistance to prevent the cover 2 from rotating in the open direction.

[0045] In this embodiment, Figure 4 and Figure 6 The torsion spring 5, with its second torsion arm 52 as the rotation axis, can rotate synchronously with the movable page plate 41 on the fixed page plate 42. When the cover 2 is opened, the torsion spring 5 is inclined relative to the bottom wall of the cavity 11; when the cover 2 is closed, the torsion spring 5 is flat relative to the bottom wall of the cavity 11.

[0046] In this embodiment, see Figure 8The second torsion arm 52 includes a transition arm 521 located outside the fixed page plate 42 and a connecting arm 522 that is limited and mounted on the fixed page plate 42. The transition arm 521 and the connecting arm 522 are integrally formed. The transition arm 521 is connected to the first torsion arm 51, and the connecting arm 522 is limited and mounted on the fixed page plate 42 by a limiting structure and can rotate. The connecting arms 522 of the two torsion springs 5 ​​are both configured as cylindrical connecting shafts, with their axes coinciding and their ends abutting against each other to ensure force balance.

[0047] In this embodiment, see Figures 6 to 8 The limiting structure includes a screw 61, a nut 62, and an anti-detachment washer 63 (which may be made of rubber or hard metal) located between them. The anti-detachment washer 63 is provided on the fixed leaf plate 42, and its side skirt 421 extending upward relative to the fixed leaf plate 42 has a cavity A for accommodating the connecting arm 522. The connecting arm 522 is located in the cavity A. The screw 61 passes through the fixed leaf plate 42 and the bottom wall of the cavity 11, and cooperates with the nut 62 to lock the anti-detachment washer 63 onto the fixed leaf plate 42. See [reference needed] Figure 7 The head of screw 61 at least partially covers the cavity A to prevent the connecting arm 522 from detaching from the cavity A. Specifically, the connecting arm 522 is placed inside the cavity A, and screw 61 passes through the central hole of the fixing plate 42 and the anti-detachment washer 63. The anti-detachment washer 63 is locked in place with nut 62, and the head of screw 61 covers at least half of the area above the cavity A, which both restricts the connecting arm 522 from detaching radially and allows it to rotate within the cavity AA.

[0048] The working principle and usage process of this utility model:

[0049] During structural installation,

[0050] First, fix the lock cylinder 31 onto the cover 2 and fix the lock seat 32 onto the charging base 1;

[0051] Second, weld the movable leaf plate 41 to the inner side of the cover 2;

[0052] Third, the movable leaf plate 41 and the fixed leaf plate 42 are connected by the shaft hole of the pin 43 to form a rotating shaft, ensuring that the cover 2 can rotate flexibly around the shaft;

[0053] Fourth, torsion springs 5 ​​are installed on the left and right ends of the pin 43 respectively. The first torsion arm 51 is inserted into the side wing hole of the movable page plate 41, and the connecting arm 522 of the second torsion arm 52 is also inserted above the fixed page plate 42 to ensure that the two torsion springs 5 ​​are opposite each other and the connecting arms 522 abut against each other.

[0054] Fifth, place the fixing plate 42 into the cavity 11 of the charging base 1, so that the two through holes on the fixing plate 42 correspond to the through holes in the cavity 11; then, pass the screw 61 through the anti-detachment washer 63, the fixing plate 42, and the bottom wall of the cavity 11 in sequence, and then complete the screw connection with the nut 62 to lock the anti-detachment washer 63 and the fixing plate 42 onto the charging base 1; at the same time, the connecting arm 522 located in the cavity A between the anti-detachment washer 63 and the side skirt 421 will also be limited by the screw 61 and cannot be radially disengaged.

[0055] When using the charging port cover of this utility model...

[0056] Before charging, the cover 2 needs to be opened (see...). Figures 1 to 3 At this point, with the cover 2 in the closed position, first turn the key to rotate the lock cylinder 31 of the locking structure (counterclockwise) to disengage the lock cylinder 31 from the lock seat 32. At this time, the cover 2 remains closed due to the elastic resistance of the torsion spring 5; that is, the torsion spring 5 generates a certain elastic force through compression and torsion. See [link to relevant documentation]. Figure 4 The torsion spring 5 is set horizontally, and its first torsion arm 51 and second torsion arm 52 generate an interaction elastic force that abuts against the side wing of the movable page plate 41 and the fixed page plate 42 respectively. This elastic force restricts the movable page plate 41 from moving toward the open position. An external force greater than the elastic force of the torsion spring 5 needs to be applied to push the cover 2 upward in order to drive the movable page plate 41 to rotate around the rotation axis.

[0057] As the force applied to the cap 2 gradually increases, the opening angle of the cap 2 increases, and the second torsion arm 52 of the torsion spring 5 rotates synchronously within the cavity A of the fixed page plate 42, while the first torsion arm 51 of the torsion spring 5 rotates upward with the movable page plate 41; see also Figure 6 When the cover 2 is opened to its maximum angle (preset 90°), the torsion spring 5 becomes tilted, and the first torsion arm 51 and the second torsion arm 52 interact to form a force in the tilting direction. The first torsion arm 51 elastically presses against the movable leaf plate 41, restricting the movable leaf plate 41 from moving in the closing direction. At this time, the charging port 12 is fully exposed for the charging gun to be inserted. Conversely, when it is necessary to close the cover 2, an external force greater than the elastic force of the torsion spring 5 must be applied to rotate and pry the cover 2 downward until the torsion spring 5 returns to its original position above the cavity 11 from tilted to flat. Finally, the lock cylinder 31 of the screw-locking structure cooperates with the lock seat 32 to completely close the cover 2. Therefore, this utility model, through the design of the V-shaped torsion spring 5, generates targeted elastic resistance during the opening and closing of the cover 2, effectively preventing the cover 2 from being accidentally opened or closed, ensuring the safety of the charging port. The overall structure is simple, and the core function is achieved through the cooperation of the hinge structure and the torsion spring 5, making it easy to manufacture and assemble.

[0058] Second Embodiment

[0059] The difference between the second embodiment and the first embodiment is that the limiting structure in the second embodiment is configured as a guide sleeve (not shown in the figure).

[0060] In this embodiment, the guide sleeve is a metal structural component, fixed on the fixed leaf plate 42, with its axis parallel to the length direction of the fixed leaf plate 42. The connecting arm 522 is inserted into the guide sleeve, allowing it to rotate along the sleeve axis while being restricted from radial wobble by the sleeve. Therefore, the sleeve structure of the guide sleeve allows the connecting arm 522 to provide stable rotational guidance, reducing radial wobble during rotation and lowering frictional losses. The simple fit between the sleeve and the connecting arm 522 requires lower machining precision, reducing manufacturing costs while improving the smoothness of the rotation process.

[0061] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
