Due to the limited or irregular complex installation space layout, this structure cannot meet the multi-degree-of-freedom unlocking requirements of the unlocking mechanism, and cannot drive the locking rod from multiple directions to complete the unlocking action.

Detailed Implementation

[0056] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0057] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0058] This application provides an unlocking mechanism, such as... Figures 1 to 4 As shown, the unlocking mechanism includes:

[0059] Locking rod structure 1, which can move along a first direction under the action of external force to unlock the part to be unlocked;

[0060] The push shaft structure 2 can move along the second direction under the action of external force, and drive the locking rod structure 1 to move along the first direction; wherein the first direction and the second direction have a certain angle.

[0061] Specifically, such as Figure 1As shown, the unlocking mechanism of this application includes a locking rod structure 1, which can move along a first direction under the action of an external force to unlock the part to be unlocked; and a push shaft structure 2, which can move along a second direction under the action of an external force and drive the locking rod structure 1 to move along the first direction; wherein, the first direction and the second direction have a certain angle. The push shaft structure 2 can reciprocate along the second direction under the drive mechanism (such as a motor) or manual drive, and the push shaft structure 2 drives the locking rod structure 1 to move along the first direction; the locking rod structure 1 can also reciprocate along the first direction under the drive mechanism (such as a motor) or manual drive, and can unlock the part to be unlocked when the locking rod structure 1 moves along the first direction. The first direction and the second direction have a certain angle, and this angle design can be adjusted according to the actual installation environment. The typical angle range is between 60° and 150°, preferably 90°, to ensure that when the push shaft structure 2 applies force in a direction perpendicular to the charging gun axis, the locking rod structure 1 can cut into the locking area at the optimal angle to achieve efficient and low-resistance unlocking. The first direction is typically up and down, and the second direction is typically left and right, but they can also be designed in opposite directions. The specific design can be adjusted according to the actual installation environment. This structure breaks through the linear dependence of traditional linear push rod structures on installation space by setting the input movement direction of the push shaft structure 2 and the output unlocking direction of the locking rod structure 1 to a non-collinear angular relationship. This allows the unlocking mechanism to be flexibly arranged in narrow areas where there is an angular offset between the charging gun and the vehicle body interface, avoiding problems such as cumbersome mechanisms or assembly failures caused by spatial interference. Simultaneously, it ensures that if the push shaft structure 2 cannot push the locking rod structure 1 from the second direction to complete the unlocking action due to power outages, maintenance, or damage to the drive mechanism, the user can manually operate the locking rod structure 1 directly from the first direction to complete the unlocking action.

[0062] In summary, the unlocking mechanism of this application, by setting a transmission structure in which the movement directions of the push shaft structure 2 and the locking rod structure 1 are not collinear, can drive the locking rod structure 1 to move along the first direction from the second direction through the push shaft structure 2 to complete the unlocking action. It can also drive the locking rod structure 1 to move directly from the first direction through external force to complete the unlocking action, thereby realizing the multi-degree-of-freedom unlocking requirements of the unlocking mechanism and solving the problems of single unlocking direction and poor spatial adaptability of unlocking mechanisms in related technologies.

[0063] In some embodiments, the unlocking mechanism includes:

[0064] The crank-connecting rod structure 3 is connected to the push shaft structure 2 and the locking rod structure 1 respectively;

[0065] The push shaft structure 2 drives the locking rod structure 1 to move along the first direction through the crank-connecting rod structure 3.

[0066] Optional, in Figure 1The unlocking mechanism also includes a crank-connecting rod structure 3, which is connected to the push shaft structure 2 and the locking rod structure 1 respectively. The push shaft structure 2 drives the locking rod structure 1 to move along the first direction through the crank-connecting rod structure 3. By introducing the crank-connecting rod structure 3, the linear motion of the push shaft structure 2 along the second direction is converted into the oscillating or sliding motion of the locking rod structure 1 along the second direction, achieving precise conversion of the motion trajectory. As the core transmission unit, the crank-connecting rod structure 3 has its geometric parameters (such as the length of the crank 31, the length of the connecting rod 32, and the hinge position) optimized through mechanical simulation to ensure that the locking rod structure 1 can obtain effective displacement within the stroke range of the push shaft 21, meeting the unlocking stroke requirements of the charging gun latch.

[0067] In some embodiments, the locking rod structure 1 includes:

[0068] The first locking rod section 11 is connected to the crank-connecting rod structure 3, and the push shaft structure 2 drives the first locking rod section 11 to move along the first direction through the crank-connecting rod structure 3.

[0069] The second locking rod segment 12 is connected to the first locking rod segment 11. The first locking rod segment 11 drives the second locking rod segment 12 to move along a side opposite to the direction of movement of the first locking rod segment 11, so as to unlock the component to be unlocked.

[0070] Optional, such as Figure 2 , Figure 3 As shown, the locking rod structure 1 includes a first locking rod segment 11 and a second locking rod segment 12. The first locking rod segment 11 is connected to the crank-connecting rod structure 3, and the push shaft structure 2 drives the first locking rod segment 11 to move in a first direction through the crank-connecting rod structure 3. The second locking rod segment 12 is connected to the first locking rod segment 11, and the first locking rod segment 11 drives the second locking rod segment 12 to move in the opposite direction to the movement of the first locking rod segment 11, so as to unlock the part to be unlocked. The locking rod mechanism is designed as a segmented locking rod design with the first locking rod segment 11 and the second locking rod segment 12, which creates a "linkage" mechanism in the kinematic chain: when the first locking rod segment 11 moves inward under the drive of the crank-connecting rod structure 3, the second locking rod segment 12 swings outward in the opposite direction due to structural constraints, thereby concentrating the unlocking action at the end of the slot structure 121. This avoids the problem of the unlocking force being dispersed due to the overall displacement of the traditional one-piece locking rod, and concentrates the unlocking force at the lock contact point, significantly improving the unlocking success rate.

[0071] In some embodiments, the second locking rod segment 12 includes:

[0072] The slot structure 121 is located at the end of the second locking rod segment 12 away from the first locking rod segment 11, and the slot structure 121 is used to unlock the unlockable part.

[0073] Optionally, the second locking rod segment 12 includes a slot structure 121. The slot structure 121 is located at the end of the second locking rod segment 12 away from the first locking rod segment 11. The slot structure 121 is used to unlock the part to be unlocked. The slot structure 121 is a U-shaped or semi-circular groove with anti-slip texture on its inner wall, forming an enveloping contact with the cylindrical boss of the charging gun latch. When the second locking rod segment 12 and the slot structure 121 move upward to a certain distance, the slot structure 121 disengages from the charging gun latch to achieve unlocking, avoiding the jamming phenomenon caused by centering deviation in traditional push-type unlocking.

[0074] In some embodiments, the second locking rod segment 12 includes a locking rod mating portion 122, which is disposed at the end of the second locking rod segment 12 near the first locking rod segment 11; the first locking rod segment 11 includes a groove-shaped structure, and the locking rod mating portion 122 is disposed within the groove-shaped structure.

[0075] Optional, in Figure 2 In the first locking rod section 11, the second locking rod segment 12 includes a locking rod mating part 122, which is located at the end of the second locking rod segment 12 near the first locking rod segment 11. The first locking rod segment 11 includes a groove-shaped structure, and the locking rod mating part 122 is disposed within the groove-shaped structure. The locking rod mating part 122 serves as a motion coupling element between the second locking rod segment 12 and the first locking rod segment 11. It is embedded in the groove-shaped structure to form a sliding guide pair, ensuring that the second locking rod segment 12 can only move in the opposite direction along a preset trajectory, thus preventing rotational offset or lateral swaying.

[0076] In some embodiments, the unlocking mechanism includes:

[0077] The first rotating shaft 4 is connected to the second locking rod segment 12, and the first locking rod segment 11 drives the second locking rod segment 12 to rotate around the first rotating shaft 4.

[0078] Optionally, the unlocking mechanism includes a first rotating shaft 4, with a second locking rod segment 12 movably connected to the first rotating shaft 4. The first locking rod segment 11 drives the second locking rod segment 12 to rotate around the first rotating shaft 4. The first rotating shaft 4 is a fixed component, fixed to the mounting base, and its material can be stainless steel. Both ends are fixed to the mounting base via bearing seats. The rotational connection method allows the second locking rod segment 12 to achieve pure rotation rather than sliding during the unlocking process, significantly reducing frictional loss and improving long-term reliability. The rotation center is aligned with the geometric center of the slot structure 121 to ensure a uniform distribution of unlocking torque.

[0079] In some embodiments, the second locking rod segment 12 includes:

[0080] A shaft hole is located between the slot structure 121 and the locking rod mating part 122;

[0081] The first rotating shaft 4 passes through the shaft hole.

[0082] Optionally, the second locking rod section 12 includes a shaft hole located between the slot structure 121 and the locking rod mating part 122; the first rotating shaft 4 passes through the shaft hole. The shaft hole is a precision-machined through hole, which fits with the first rotating shaft 4 to ensure zero clearance during rotation. This structure can maintain positioning accuracy even under vibration, avoiding unlocking offset due to loosening.

[0083] In some embodiments, the unlocking mechanism includes a first elastic element 13 and a first fixed limiting portion 10, and the first locking rod segment 11 includes a button 111; the first elastic element 13 is disposed between the button 111 and the first fixed limiting portion 10, and the first elastic element 13 is used to reset the first locking rod segment 11.

[0084] Optional, such as Figure 3 , Figure 4 As shown, the unlocking mechanism includes a first elastic element 13 and a first fixed limiting part 10. The first locking rod segment 11 includes a button 111. The first elastic element 13 is disposed between the button 111 and the first fixed limiting part 10, and is used to reset the first locking rod segment 11. The button 111 is made of plastic or metal and is manually triggered by the user. The first fixed limiting part 10 is also a fixing element, fixed to the mounting base. When not under force, the first elastic element 13 maintains the first locking rod segment 11 in its initial locked position. When the push shaft structure 2 drives the locking rod structure 1 to move in the first direction, or when the button 111 is manually operated to drive the locking rod structure 1 to move in the first direction, the first elastic element 13 stores potential energy and automatically rebounds after the external force is removed, achieving automatic reset of the locking rod structure 1 without the need for an additional power source.

[0085] In some embodiments, the first locking rod segment 11 includes a limiting shaft 112, the button 111 is connected to the limiting shaft 112, and the limiting shaft 112 is located between the button 111 and the first fixed limiting part 10; the first elastic member 13 includes a first spring structure, and the first spring structure passes through the limiting shaft 112.

[0086] Optionally, the first locking rod segment 11 includes a limiting shaft 112, with the button 111 connected to the limiting shaft 112. The limiting shaft 112 is located between the button 111 and the first fixed limiting part 10. The first elastic element 13 includes a first spring structure, which passes through the limiting shaft 112. The limiting shaft 112 is a stepped shaft structure, with one end welded to the button 111, or the button 111 and the limiting shaft 112 being an integrally formed structure. The other end is inserted into the guide hole of the first fixed limiting part 10, and the first spring structure is sleeved on the intermediate rod segment. This structure ensures that the first spring structure is subjected to uniform force along the axial direction of the limiting shaft 112, avoiding spring failure caused by eccentric compression.

[0087] In some embodiments, the unlocking mechanism includes a second fixed limiting part 20, at least a portion of the first locking rod segment 11 is disposed on the second fixed limiting part 20; the second fixed limiting part 20 is used to limit the displacement of the first locking rod segment 11 in a third direction.

[0088] Optionally, the unlocking mechanism includes a second fixing limiting part 20, with at least a portion of the first locking rod segment 11 disposed on the second fixing limiting part 20; the second fixing limiting part 20 is used to limit the displacement of the first locking rod segment 11 in a third direction. The second fixing limiting part 20 is a metal bracket with a guide groove on its inner wall, matching the side profile of the first locking rod segment 11 to limit its offset in a third direction (i.e., lateral) perpendicular to the first and second directions. The second fixing limiting part 20 is also a fastener, fixed to the mounting base, and is usually located in the middle position of the first locking rod segment 11. This structure effectively prevents the first locking rod segment 11 from laterally vibrating under high-frequency vibration.

[0089] In some embodiments, the crank-connecting rod structure 3 includes:

[0090] Crank 31, which is connected to the push shaft structure 2, and the push shaft structure 2 drives the crank 31 to move along the second direction;

[0091] The connecting rod 32 is connected to the crank 31 and the first locking rod section 11 respectively. During the movement of the crank 31 in the second direction, it drives the connecting rod 32 to move in the first direction.

[0092] Optionally, the crank-connecting rod structure 3 includes a crank 31 and a connecting rod 32. The crank 31 is connected to the push shaft structure 2, which drives the crank 31 to move in a second direction. The connecting rod 32 is connected to both the crank 31 and the first locking rod section 11. During the movement of the crank 31 in the second direction, it drives the connecting rod 32 to move in the first direction. The crank 31 is a forged steel part with a certain radius of rotation and is connected to the push shaft structure 2 via a second hinge 34. When the push shaft structure 2 pushes the crank 31 to move in the second direction, the crank 31 rotates around the second hinge 34, thereby converting the motion into displacement of the first locking rod section 11 in the first direction through the connecting rod 32, achieving efficient transmission of force and displacement.

[0093] In some embodiments, the link 32 includes:

[0094] The snap-fit ​​component 321 is connected to the first locking rod segment 11 and is used to drive the first locking rod segment 11 to move along the first direction.

[0095] Optionally, the connecting rod 32 includes a locking member 321, which is connected to the first locking rod section 11. The locking member 321 is used to drive the connecting rod 32 to move in a first direction. The locking member 321 is a pin structure with a boss or a T-shaped structure, which cooperates with the first locking rod section 11 to drive the first locking rod section 11 to move in the first direction.

[0096] In some embodiments, the first locking rod segment 11 includes:

[0097] The snap-fit ​​hole 113 is through which the snap-fit ​​member 321 passes.

[0098] Optionally, the first locking rod segment 11 includes a snap-fit ​​hole 113, and a snap-fit ​​member 321 passes through the snap-fit ​​hole 113. The snap-fit ​​hole 113 is a through hole, and the snap-fit ​​member 321 passes through the snap-fit ​​hole 113. The T-shaped structure of the snap-fit ​​member 321 can pull the first locking rod segment 11 to move in a first direction.

[0099] In some embodiments, the crank-connecting rod structure 3 includes:

[0100] The first hinge 33 is connected to the connecting rod 32 and the crank 31 respectively;

[0101] The crank 31 can rotate along the first hinge 33.

[0102] Optionally, the crank-connecting rod structure 3 includes a first hinge 33, which is connected to both the connecting rod 32 and the crank 31; the crank 31 is rotatable along the first hinge 33. During the rotation of the crank 31 along the first hinge 33, the crank 31 pulls the connecting rod 32 to move in a first direction.

[0103] In some embodiments, the crank-connecting rod structure 3 includes:

[0104] The second hinge 34 is connected to the push shaft structure 2 and the crank 31 respectively;

[0105] The crank 31 can rotate along the second hinge 34.

[0106] Optionally, the crank-connecting rod structure 3 includes a second hinge 34, which is connected to the push shaft structure 2 and the crank 31 respectively; the crank 31 can rotate along the second hinge 34. During the process of the push shaft structure 2 driving the crank 31 and the second hinge 34 to move in a second direction, one end of the crank 31 rotates along the first hinge 33, while the other end rotates along the first hinge 33, pulling the connecting rod 32 to move in a first direction. Through the cooperation of the crank 31 with the first hinge 33 and the second hinge 34, the second-direction movement of the push shaft structure 2 is converted into the first-direction movement of the connecting rod 32, which then drives the first locking rod segment 11 to move in the first direction. In some embodiments, the unlocking mechanism includes:

[0107] The third fixed limiting part 30 is provided with the connecting rod 32, and the third fixed limiting part 30 is used to limit the displacement of the connecting rod 32 in the second direction.

[0108] Optionally, the unlocking mechanism includes a third fixed limiting part 30, in which the connecting rod 32 is disposed. The third fixed limiting part 30 is used to limit the displacement of the connecting rod 32 in the second direction. The third fixed limiting part 30 is also a fixing member, fixed to the mounting base. The third fixed limiting part 30 is a U-shaped guide rail in which the connecting rod 32 can slide, restricting its movement only in the second direction, preventing lateral sway, and reducing the impact of lateral stress on the first hinge 33 and the second hinge 34.

[0109] In some embodiments, the push shaft structure 2 includes:

[0110] Push shaft 21, which is connected to crank 31 via the second hinge 34.

The fourth fixed limiting part 40 is also a fixing member, fixed on the mounting base. The limiting member 22 is an annular baffle, threadedly connected to the push shaft 21, or it can be welded to the push shaft 21 or be an integrally formed structure. During the movement of the push shaft 21 in the second direction, the limiting member 22 and the fourth fixed limiting part 40 compress the second elastic member 23. The second elastic member 23 can act as a buffer to maintain the linear movement of the push shaft 21, while preventing excessive thrust from damaging other components; after the drive mechanism (such as a motor) or manual release of the drive push shaft 21, the second elastic member 23 is used to reset the push shaft 21.

[0114] In some embodiments, the second elastic element 23 includes a second spring structure that passes through the push shaft 21.

[0115] Optionally, the second elastic element 23 includes a second spring structure that passes through the push shaft 21. The second spring structure is a stainless steel helical spring, with a hole passing through the push shaft 21, forming an axial compression circuit with the limiting element 22 and the fourth fixed limiting part 40, ensuring that the push shaft 21 automatically retracts to its initial position when there is no external force; at the same time, the second elastic element 23 passing through the push shaft 21 can limit the swing of the second elastic element 23 in the non-movement direction.

[0116] When Figure 4 As shown, the drive mechanism (such as a motor) drives the push shaft 21 from position 21' to position 21. The push shaft 21 compresses the second elastic element 23 and drives the second hinge 34 and the lower end of the crank 31 to move together in the second direction. At this time, the lower end of the crank 31 rotates around the second hinge 34, moving from position 31' to position 31; at the same time, the upper end of the crank 31 rotates around the first hinge 33. During this process, the crank 31 changes from a vertical state to an inclined state. At the first connection point between the crank 31 and the connecting rod 32... The hinge 33 is subjected to a pulling force in the tilt direction, which generates horizontal and vertical components. The vertical component drives the connecting rod 32 and the latching member 321 of the connecting rod 32 to move along the first direction, so that the latching member 321 moves from position 321' to position 321, which drives the entire first connecting rod 32 segment to move along the first direction (such as the button 111 moving from position 111' to position 111), so that the slot structure 121 moves from position 121' to position 121, thereby unlocking the unlocking member.

[0117] In some embodiments, the component to be unlocked includes a charging gun.

[0118] Optionally, the component to be unlocked includes a charging gun.

[0119] This application also provides an unlocking device, which includes the unlocking mechanism of any of the above embodiments.

[0120] Specifically, the unlocking device of this application includes the aforementioned unlocking mechanism, which can be integrated into the charging pile or vehicle. It can achieve one-click unlocking by driving the push shaft structure 2 by a motor or by triggering the unlocking device by a manual button 111. It is suitable for public charging stations, home charging piles and vehicle emergency unlocking scenarios.

[0121] The unlocking device of this application adopts the above-mentioned unlocking mechanism. By setting a transmission structure in which the movement directions of the push shaft structure 2 and the locking rod structure 1 are not collinear, the unlocking action can be completed by driving the locking rod structure 1 to move along the first direction from the second direction through the push shaft structure 2. Alternatively, the locking rod structure 1 can be directly driven to move from the first direction by external force to complete the unlocking action. This realizes the multi-degree-of-freedom unlocking requirements of the unlocking mechanism and solves the problems of single unlocking direction and poor spatial adaptability of unlocking devices in related technologies.

[0122] This application also provides an application device, which includes the unlocking mechanism of any of the above embodiments, and / or the unlocking device described above.

[0123] Specifically, the application equipment of this application can be electric vehicles, charging piles, battery swapping stations or intelligent parking systems, whose charging interface modules have the unlocking mechanism or unlocking device built in, realizing automatic and manual dual-mode unlocking, significantly improving user experience and system security.

[0124] The application device of this application adopts the above-mentioned unlocking mechanism or unlocking device.
