Description

Technical Field

[0001] This invention relates to the field of electric vehicle charging equipment technology, and in particular to an electronic lock motor for a charging gun. Background Technology

[0002] The electric vehicle charging gun is a key component connecting the charging station and the vehicle for power transmission. To ensure a safe and reliable charging process and prevent accidental interruptions or arcing risks caused by accidental disconnection or vehicle movement, modern charging guns typically integrate an electronic lock function. The basic principle is that a motor inside the gun drives a locking bolt to extend and engage with the corresponding slot in the vehicle's charging port, achieving mechanical locking. When charging is complete, the motor drives the locking bolt to retract and unlock.

[0003] However, in real-world applications, even after the charging gun is locked to the vehicle, it may still face abnormal and significant external impacts, such as the vehicle being accidentally dragged while it is still locked, or people or other objects tripping and pulling on the charging cable.

[0004] At this point, if the locking mechanism remains rigidly locked, the enormous pulling force may directly cause irreversible mechanical damage to the lock tongue, motor transmission mechanism, or vehicle charging port, resulting in high repair costs.

[0005] There is an urgent need for a technical solution for overload protection mechanism of electronic lock for charging guns to avoid irreversible damage. Summary of the Invention

[0021] The present invention will now be clearly and completely described with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are exemplary, and the present invention is not limited to the specific embodiments described herein.

[0022] Please see Figure 1 and Figure 2As shown, the charging gun electronic lock motor in this embodiment of the invention includes: a charging gun body 1, one end of which is provided with a charging plug 2 for insertion into the charging interface of an electric vehicle to transmit electrical energy; a locking component 6 is also fixedly provided at one end of the charging gun body 1, the locking component 6 including a locking plug 601 and a locking tenon 602, the locking plug 601 being fixedly provided at the side of the charging plug 2, the locking plug 601 being provided with a slidable locking tenon 602, the locking tenon 602 being used to engage with a slot in the vehicle charging port when extended, thereby achieving mechanical locking of the charging gun.

[0023] A fixed chamber 5 is fixedly connected to the outer wall of the charging gun body 1, and a connecting cable 4 is connected to the other end of the charging gun body 1 through a buffer tail assembly 3, forming a cable connection structure with stress buffering function.

[0024] The fixed chamber 5 is also equipped with an overload unlocking component 7, which is connected to the buffer tail component 3. When the buffer tail component 3 is in an overloaded tension state, it senses the tension and automatically triggers the locking component 6 to unlock.

[0025] This invention uses a buffer tail component 3 to sense abnormal tension, an overload unlocking component 7 to convert mechanical displacement into an unlocking action, and a linkage reset component 8 to achieve protection and reset. It can trigger mechanical unlocking when an unexpected overload occurs, thereby protecting the equipment. The entire protection mechanism can be reset subsequently. It is particularly suitable for public and home electric vehicle charging scenarios where the safety and continuity of use of the equipment are highly required.

[0026] In a preferred embodiment of the present invention, see [reference needed]. Figure 3 and Figure 4 As shown, the locking assembly 6 also includes a guide slider 603 and an unlocking unit. The guide slider 603 is disposed in the inner cavity of the fixed chamber 5. The guide slider 603 is fixedly connected to the locking tenon 602 to form a synchronously moving whole. It is used to directly transmit the linear motion of the guide slider 603 to the locking tenon 602 to control its extension and retraction.

[0027] Furthermore, in order to ensure the stability and accuracy of the movement direction of the locking latch 602, a number of fixed guide rods 604 are fixedly connected in the inner cavity of the fixed chamber 5, preferably four. The four fixed guide rods 604 all pass through the guide slider 603 and slide with the guide slider 603 to form a stable guide pair.

[0028] A connecting spring 605 is also fixedly connected to the upper surface of the guide slider 603. The other end of the connecting spring 605 is fixedly connected to the upper wall of the inner cavity of the fixing chamber 5 to provide a preload force that keeps the locking latch 602 extending.

[0029] Preferably, such as Figure 2 or Figure 6 As shown, one side of the locking tenon 602 is a bevel or arc surface, which is used to contact and be squeezed with the edge of the charging port when the charging plug 2 is inserted into the vehicle charging port, thereby guiding the locking tenon 602 to retract automatically. With this technical solution, when the charging plug is fully inserted, the elastic force of the connecting spring 605 pushes the guide slider 603 and the locking tenon 602 to return to their original position and extend, thereby automatically locking into the slot of the charging port to achieve locking, thus eliminating the need for additional locking operations.

[0030] For a preferred technical solution, please refer to Figure 4 and Figure 5 As shown, the unlocking unit of the locking assembly 6 includes an unlocking turntable 606, a first protrusion 607 and a second protrusion 608. The unlocking turntable 606 is disposed in the inner cavity of the fixed chamber 5 and is rotatably connected to the fixed chamber 5.

[0031] A first protrusion 607 is fixedly connected to the unlocking turntable 606, and a second protrusion 608 is fixedly connected to the guide slider 603. When the unlocking turntable 606 rotates, the first protrusion 607 and the second protrusion 608 interact. When the control motor 611 drives the unlocking turntable 606 to rotate, the first protrusion 607 can push the second protrusion 608, thereby causing the guide slider 603 to move in the retracting direction against the elastic force of the connecting spring 605.

[0032] The unlocking turntable 606 is also connected to a rotary drive unit to provide the rotational power required for unlocking.

[0033] Further, see Figure 4 As shown, the rotary drive unit includes a rotary drive rod 609 and a control motor 611. The rotary drive rod 609 is rotatably connected in the inner cavity of the fixed chamber 5. The rotary drive rod 609 is fixedly connected to the unlocking turntable 606 and is used to transmit the rotary motion to the unlocking turntable 606.

[0034] A control motor 611 is also fixedly installed in the inner cavity of the fixed chamber 5. The control motor 611 is connected to the rotary drive rod 609 for transmission and is used to provide a power source for the active unlocking of the entire locking assembly 6.

[0035] Specifically, a first bevel gear 610 is fixedly connected to the arc-shaped wall of the rotary drive rod 609, and a second bevel gear 612 is fixedly connected to the end of the output shaft of the control motor 611. The second bevel gear 612 and the first bevel gear 610 mesh with each other.

[0036] With the above technical solution, when the control motor 611 is started, the second bevel gear 612 drives the first bevel gear 610 and the rotary drive rod 609 to rotate, thereby driving the unlocking turntable 606 to rotate, thus realizing the electric unlocking function of the locking tenon 602 controlled by the electrical signal.

[0037] In order to solve the problem that in the existing technology, when the cable of a conventional charging gun is accidentally pulled, the pulling force is directly transmitted to the inside of the gun body, which can easily lead to loosening of the internal connector or damage to the locking mechanism, the present invention designs a buffer tail assembly 3.

[0038] In one specific embodiment of the present invention, see [reference needed]. Figure 6 As shown, the buffer tail assembly 3 includes a fixed sleeve 301, a sliding sleeve 302 and a buffer spring 303. The fixed sleeve 301 is fixedly installed at one end of the charging gun body 1, and the sliding sleeve 302 is sleeved on the fixed sleeve 301 to form a sleeve structure that can slide relative to each other axially.

[0039] A buffer spring 303 is also fixedly connected between the fixed sleeve 301 and the sliding sleeve 302, which provides a restoring force after the sliding sleeve 302 is stretched and generates a preset displacement when overloaded.

[0040] A connecting cable 4 is fixedly connected to one end of the sliding sleeve 302. A spiral cable 304 is fixedly connected between the sliding sleeve 302 and the charging gun body 1. The spiral cable 304 and the connecting cable 4 are electrically connected to maintain the continuity and reliability of the electrical connection when the sliding sleeve 302 extends or retracts.

[0041] With this technical solution, when the connecting cable 4 is subjected to abnormal axial tension, the sliding sleeve 302 can be pulled to slide relative to the fixed sleeve 301 and stretch the buffer spring 303, thereby absorbing part of the energy and preventing the tension from acting entirely on the charging gun body 1.

[0042] With the setting of the buffer tail assembly 3, when the connecting cable is accidentally pulled, the energy can be absorbed and buffer displacement can be generated by the deformation of the buffer spring 303, thereby protecting the internal structure of the charging gun. The greater the external force, the greater the stretch of the buffer spring 303, and the greater the displacement of the sliding sleeve 302.

[0043] In a preferred embodiment of the present invention, see [reference needed]. Figure 7 and Figure 9 As shown, the overload unlocking assembly 7 includes a lifting plate 701 and a movement control unit 705. The lifting plate 701 is disposed in the inner cavity of the fixed chamber 5 and is rotatably connected to the fixed chamber 5 to form a lever structure.

[0044] Specifically, a fixed shaft 702 is rotatably connected to the middle position of the lifting plate 701, and the fixed shaft 702 is fixedly installed in the inner cavity of the fixed chamber 5; it serves as a fulcrum for the rotation of the lifting plate 701.

[0045] One end of the lifting plate 701 is provided with a rectangular slide groove 7011, and one end of the guide slider 603 is provided with a guide post 6031. The guide post 6031 and the rectangular slide groove 7011 slide together to form a sliding pair. When the lifting plate 701 rotates around the fixed shaft 702, its other end pushes the guide post 6031 and the guide slider 603 through the rectangular slide groove 7011, thereby driving the locking tenon 602 to move in the unlocking direction.

[0046] A connecting spring 703 is also fixedly connected to the bottom surface of the lifting plate 701.

[0047] Furthermore, a first inclined block 704 is fixedly connected to one end of the lifting plate 701, and a movable movement control unit 705 is provided in the inner cavity of the fixed chamber 5. A second inclined slider 706 is fixedly connected to one end of the movement control unit 705. The second inclined slider 706 is used to cooperate with the inclined surface of the first inclined block 704 to convert the linear motion of the movement control unit 705 into the rotational motion of the lifting plate 701.

[0048] One end of the movement control unit 705 is fixedly connected to the outer wall of the sliding sleeve 302 to form a mechanical linkage. When the sliding sleeve 302 is displaced due to overload tension, it can drive the movement control unit 705 and the second inclined plane slider 706 to move, thereby pushing the first inclined plane block 704 and the lifting plate 701 to rotate and trigger unlocking.

[0049] Furthermore, to allow adjustment of the tension threshold required to trigger overload protection, see [reference needed]. Figure 7 As shown, the motion control unit 705 includes a first connecting arm 7051 and a second connecting arm 7052. The second connecting arm 7052 is fixedly disposed on the outer wall of the sliding sleeve 302. An inner cavity is provided inside the second connecting arm 7052. The first connecting arm 7051 is slidably connected in the inner cavity of the second connecting arm 7052, forming a linkage mechanism with adjustable length.

[0050] As a specific technical solution, a fixing sleeve 7053 is fixedly connected in the inner cavity of the first connecting arm 7051, and an adjusting screw 7054 is rotatably connected in the inner cavity of the second connecting arm 7052. The adjusting screw 7054 passes through the fixing sleeve 7053 and is threadedly engaged with the fixing sleeve 7053. A transmission rod 7055 is fixedly connected to one end of the adjusting screw 7054, and a first bevel gear 7056 is fixedly connected to the arc-shaped wall of the transmission rod 7055.

[0051] A rotatable adjustment knob 7057 is provided on the outer wall of the second connecting arm 7052. A second bevel gear 7058 is fixedly connected to one end of the adjustment knob 7057. The second bevel gear 7058 meshes with the first bevel gear 7056 to transmit the rotational movement of the adjustment knob 7057 to the adjustment screw 7054.

[0052] With the above technical solution, the adjustment knob 7057 can be rotated to drive the adjustment screw 7054 to rotate through the bevel gear pair, thereby pushing the first connecting arm 7051 into or out of the inner cavity of the second connecting arm 7052 through the threaded engagement, thereby adjusting the total length of the movement control unit 705.

[0053] With the stiffness of the buffer spring 303 fixed, adjusting the length of the moving control unit 705 changes the displacement of the sliding sleeve 302 required to trigger unlocking, which is equivalent to adjusting the trigger threshold of the overload tension.

[0054] In a preferred embodiment of the present invention, see [reference needed]. Figure 8 and Figure 9 As shown, in order to prevent the locking tongue from extending again due to automatic reset of the mechanism before the abnormal pulling force disappears after overload unlocking, a linkage reset component 8 is also fixedly connected to the movement control unit 705. The linkage reset component 8 includes a one-way limit unit and a reset unit.

[0055] The one-way limiting unit includes a toothed plate 801 and a ratchet 804. The toothed plate 801 is fixedly installed on the outer wall of the movement control unit 705, and a plurality of limiting tooth grooves that cooperate with the ratchet 804 are provided on the toothed plate 801.

[0056] A fixed seat 802 is also fixedly connected in the inner cavity of the fixed chamber 5. A limit slider 803 is slidably connected in the inner cavity of the fixed seat 802. A ratchet 804 is fixedly connected to the side wall of the limit slider 803. One end of the ratchet 804 extends to the tooth groove movement path of the tooth plate 801.

[0057] The other end of the limit slider 803 is provided with a positioning spring 806, which is used to keep the ratchet 804 engaged with the toothed plate 801. With this technical solution, when an overload occurs, when the movement control unit 705 moves in the triggering direction, it can drive the toothed plate 801 to move. At this time, the ratchet 804 slides along the back of the tooth of the toothed plate 801 and will not block it. When the overload is triggered, the ratchet 804 is locked into the current tooth groove of the toothed plate 801 under the action of the positioning spring 806, thereby preventing the movement control unit 705 from rebounding under the action of the buffer spring 303, playing a mechanical locking role and preventing the unlocked state from being accidentally restored.

[0058] Further, see Figure 10 As shown, a disc 805 is rotatably connected in the inner cavity of the fixed base 802. One end of a positioning spring 806 is connected to the eccentric position of the disc 805. When the disc 805 rotates, it can change the pulling direction of the positioning spring 806, thereby driving the limit slider 803 connected to the positioning spring 806 to move, so that the ratchet 804 disengages from the toothed plate 801, realizing the manual or electric reset preparation of the overload protection state.

[0059] Furthermore, see Figure 9 and Figure 10 As shown, the reset unit includes a rotating link 807, a first link 811, and a second link 812. The rotating link 807 is rotatably connected in the inner cavity of the fixed chamber 5, and one end of the rotating link 807 is fixedly connected to the disk 805.

[0060] A first transmission gear 808 is fixedly connected to the arc-shaped wall of the rotating connecting rod 807, and a second transmission gear 809 is rotatably connected in the inner cavity of the fixed chamber 5. The second transmission gear 809 and the first transmission gear 808 mesh with each other.

[0061] A movable rack 810 is slidably connected in the inner cavity of the fixed chamber 5. The movable rack 810 meshes with the second transmission gear 809. One end of the movable rack 810 is rotatably connected to one end of the first connecting rod 811. The other end of the first connecting rod 811 is rotatably connected to the second connecting rod 812. One end of the second connecting rod 812 is fixedly connected to the unlocking turntable 606.

[0062] With this technical solution, when the control motor 611 drives the unlocking turntable 606 to rotate in the unlocking direction, the moving rack 810 can be pulled simultaneously through the second link 812 and the first link 811, thereby driving the second transmission gear 809 and the first transmission gear 808 to rotate, and finally driving the rotating link 807 and the disc 805 to rotate, so that the ratchet 804 disengages from the toothed plate 801.

[0063] By setting the linkage reset component 8, the locking of the one-way limit unit to the movement control unit 705 can be automatically released while the control motor 611 executes the normal unlocking command, realizing the restoration of the overload protection state. This solves the problem of inconvenient reset after the overload protection mechanism is triggered or the reset is disconnected from the main control logic in the prior art. Thus, after the fault is cleared, the entire locking structure and mechanical overload protection mechanism can be fully reset to the ready state through a single active unlocking operation.

[0064] In summary, the present invention has been described in detail through specific embodiments. However, the above description is only a preferred embodiment of the present invention, and various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should fall within the protection scope of the present invention, which is defined by the appended claims.
