Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicle charging, and in particular, relates to a charging gun for a new energy vehicle. Background Art

[0002] The charging gun is a key component for charging new energy vehicles. Its main function is to transmit the power of the charging cabinet or the socket strip to the battery in the new energy vehicle. In order to prevent the charging gun from accidentally falling off or being directly pulled out during the charging process, the charging gun is currently equipped with an anti-falling device and a dustproof device.

[0003] The anti-detachment device of the charging gun includes a button, a lock plate, and an electromagnetic lock. After the charging gun is inserted into the socket, the lock plate and the socket are locked with each other. When the button is pressed, the lock plate can be driven to move upward and contact the lock with the plug plate. When the charging gun is in the charging state, the lock rod on the electromagnetic lock extends outward and blocks under the button, so that the button enters the locked state to prevent the button from being pressed during the charging process. After charging is completed, the lock rod automatically retracts inward and the button enters the unlocked state. At this time, you can press the button to contact the lock between the charging gun and the socket.

[0004] The above-mentioned anti-dropping device is currently widely used in charging guns of various sizes due to its simple structure. However, in actual use, the following inconveniences still exist: there is a lack of structure for manual locking control of the button, and each locking or unlocking of the button needs to be achieved through an electromagnetic lock, which is not convenient enough; when the charging gun is powered off, the button cannot be locked or unlocked. If the charging gun is powered off on the socket, it may also cause the charging gun to be unable to be unplugged, affecting its normal use. Summary of the invention

[0005] The existing charging gun lacks a structure for manually locking and controlling the button. The locking and unlocking of the button rely on the control of the electromagnetic lock, which is inconvenient. Moreover, when the charging gun is powered off, the button cannot be locked or unlocked. To solve the above problems, the following invention is proposed:

[0006] A charging gun for new energy vehicles comprises a gun body and a plug, wherein a lock plate, a button and an electromagnetic lock are arranged on the gun body, a lock head is arranged at the end of the lock plate, and when the button is pressed, the lock plate is driven to lift upward near one end of the lock head, and a retractable lock rod is arranged on the electromagnetic lock, and the lock rod is blocked under the button after extending outward, and an outward push block and an inward push block are also arranged on the gun body, and a push arm engaged with the inward push block is arranged on the outward push block, and a locking block and an unlocking block are arranged on the inward push block, and the locking block is blocked between the button and the lock rod, and the unlocking block is located on one side of the lock rod.

[0007] After the locking rod extends outward, the unlocking block pushes the inner pushing block to move. After the inner pushing block moves, it drives the locking block to block under the button. At this time, the button enters a locked state and cannot be pressed downward; after the outer pushing block moves, it drives the locking block and the unlocking block to move together through the inner pushing block. After the locking block moves, it no longer blocks the button. The locking rod is also pushed by the unlocking block to shrink inward, and the button enters an unlocked state and can be pressed downward; after the outer pushing block is moved in the opposite direction, the locking block is blocked under the button again, and the button enters a locked state again.

[0008] Even if the electromagnetic lock is powered off and the locking rod cannot be controlled, the operator can manually move the push-out block to allow the locking block to lock or unlock the button, thereby preventing the gun body from being locked and improving reliability during use.

[0009] Furthermore, it also includes an anti-touch cover blocking the top of the button, the push-out block is provided with a slot, the anti-touch cover is provided with an insert block that fits and is inserted into the slot, and when the push-out block moves, the anti-touch cover moves with it.

[0010] Furthermore, guide grooves and slide blocks are respectively provided on both sides of the gun body, a guide column which is inserted into the guide groove is provided on one side of the anti-touch cover, and a slide groove which is movably inserted into the slide block is provided on the other side.

[0011] Furthermore, a first pushing portion is provided on one side of the anti-touch cover, and the first pushing portion includes a plurality of groove-shaped structures. The groove-shaped structures on the first pushing portion can increase the stability when the operator pushes the anti-touch cover.

[0012] Furthermore, it also includes a dust cover mounted on the outside of the plug, the top of the dust cover is provided with a lock groove for the lock head to fit into, a mounting seat is provided at the bottom of the gun body, and a movable arm is provided at the bottom of the dust cover. The movable arm is movably arranged on the mounting seat and can drive the dust cover to move horizontally relative to the mounting seat. After the dust cover moves to detach from the plug, the movable arm can also drive the dust cover to rotate downward relative to the mounting seat.

[0013] Furthermore, a guide hole is penetrated through the mounting seat, and a connecting rod is provided at the end of the movable arm. The connecting rod is movably arranged in the guide hole and can move horizontally and rotate in the guide hole.

[0014] Furthermore, a snap-fit ​​hole is provided on the gun body, and a snap-fit ​​head is provided on the dust cover. After the dust cover is separated from the plug and moves along the mounting seat, the snap-fit ​​head can cooperate with the snap-fit ​​hole to fix the dust cover.

[0015] Furthermore, a second push portion is provided at the bottom of the dust cover, and a plurality of groove-shaped structures are provided on the second push portion. Similarly, the operator can quickly move the dust cover by pressing the second push portion.

[0016] In summary, compared with the existing charging guns for new energy vehicles, the present invention has the following advantages: (1) Regardless of whether the gun body itself is connected to the power supply, the operator can lock or unlock the button by manually controlling the movement of the push-out block to prevent the gun body from being locked by the lock plate, which is more reliable; (2) A dust cover is installed on the gun body to facilitate opening the dust cover and re-covering the plug, and the dust cover is not easy to lose, which is more convenient.

These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0030] In addition to being used to indicate a position or location relationship, some of the above terms may also be used to indicate other meanings. For example, the term "on" may also be used to indicate a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0031] like Figure 1-Figure 2 As shown in the figure, it is a preferred embodiment of the present invention, a charging gun for a new energy vehicle, comprising a gun body 1 and a plug 2 installed at the end of the gun body 1, a button 3 and a lock plate 11 are elastically connected at the top of the gun body 1, an extension block 31 extending vertically downward is provided at the bottom of the button 3, and a lock head 12 is provided at the end of the lock plate 11. After the plug 2 is inserted into the charging socket of the car, the lock head 12 cooperates with the groove structure on the socket to lock the plug 2 with the socket. After the button 3 is pressed, the lock plate 11 is driven to lift up the end close to the lock head 12 to release the lock between the plug 2 and the socket; an electromagnetic lock 13 is provided inside the gun body 1, and a retractable lock rod 14 is provided on the electromagnetic lock 13. After the gun body 1 is powered on, the extension of the lock rod 14 is controlled by the electric control system. After the plug 2 is inserted into the charging socket, the lock rod 14 automatically extends outward and blocks below the extension block 31 of the button 3 to prevent the button 3 from being pressed downward, thereby preventing the charging gun from being separated from the socket during the charging process.

[0032] like Figure 3-Figure 5 As shown, the gun body 1 is also movably provided with an outward push block 32 located on the outside of the gun body 1 and an inner push block 34 inside the gun body 1, the outward push block 32 is provided with a push arm 33, and the inner push block 34 is provided with a notch 35, a locking block 36, and an unlocking block 37, the push arm 33 is engaged in the notch 35, so that after the outward push block 32 is pushed to move horizontally, it drives the inner push block 34 to move horizontally together, and the locking block 36 is blocked between the extension block 31 and the locking rod 14, so that the locking rod 14 will not contact the extension block 31, and a columnar structure is also provided on one side of the locking block 36, which is movably inserted into and matched with the columnar structure set in the gun body 1 to realize the installation of the locking block 36, and the unlocking block 37 is blocked at the end side of the locking rod 14.

[0033] According to the conditions of the charging gun and the electromagnetic lock 13, the following three conditions can be classified: (1) When the locking rod 14 is in the extended state and the gun body 1 is in the powered state, the unlocking block 37 is pressed by the end of the locking rod 14, so that the inner push block 34 cannot move horizontally, and the locking block 36 is blocked directly below the extension block 31 to prevent the button 3 from being pressed downward. In this case, the locking and unlocking of the button 3 on the gun body 1 are preferentially controlled by the electromagnetic lock 13 to prevent the operator from directly unplugging the plug 2 from the socket when the gun body 1 is in the charging state, thereby damaging the plug; (2) When the locking rod 14 is in the extended state, the gun body 1 is powered off. At this time, the electromagnetic lock 13 loses control of the locking rod 14, and drives the inner push block 34 to move by horizontally moving the outer push block 32. The inner push block 34 then drives the locking block 36 and the unlocking block 37. When the lock rod 14 is in the inward contraction state, the unlocking block 37 is not pressed by the lock rod 14. Whether the gun body 1 is powered on or not, the unlocking block 37 does not affect the normal movement of the push-out block 32. The button 3 is locked or unlocked by the locking block 36. When the gun body 1 is powered on, the lock rod 14 of the electromagnetic lock 13 can force the button 3 to enter the locked state.

[0034] The operator can manually lock and unlock the button 3 by moving the push block 32, or use only the electromagnetic lock 13 to lock and unlock the button 3 like a common charging gun. In this case, manual control cannot directly unlock the button 3 to ensure the safe use of the charging gun.

[0035] Furthermore, if Figure 1 and Figure 6 As shown, it also includes an anti-touch cover 4 arranged above the button 3, and arm plates 41 extending downward to both sides of the gun body 1 are respectively provided on both sides of the anti-touch cover 4, and an insertion block 46 and a slide groove 44 are provided on the inner side of the arm plate 41 close to the side of the push-out block 32, and a slot 47 for the insertion block 46 to be inserted is provided on the push-out block 32. A first pushing portion 48 is provided on the outer side of the arm plate 41, and the first pushing portion 48 includes a plurality of groove-like structures, and sliders 45 and guide grooves 43 are respectively provided on both sides of the gun body 1, and the slider 45 is movably inserted into the slide groove 44, and a threaded guide column 42 is provided on the other side of the arm plate 41, and the guide column 42 is movably inserted into the guide groove 43.

[0036] When the button 3 is blocked by the locking block 36 and is locked, the anti-touch cover 4 is blocked just above the button 3. On the one hand, the operator can directly know whether the gun body 1 is currently manually locked. On the other hand, it prevents the operator from pressing the button 3, reducing unnecessary pressure on the locking block 36. After the push-out block 32 and the anti-touch cover 4 are moved at the same time by pressing the first pushing portion 48, the slide groove 44 moves along the slider 45, and the guide column 42 moves along the guide groove 43. When the push-out block 32 is pushed to the button 3 in the unlocked state, the anti-touch cover 4 releases the barrier on the button 3. At this time, the button 3 can be pressed and it must be in the unlocked state.

[0037] In this embodiment, a dust cover 5 is also provided on the outside of the plug 2 to reduce dust from entering the plug 2 when the gun body 1 is idle. A lock groove 56 is provided on the top of the dust cover 5 for the lock head 12 to fit in. Through the above-mentioned manual locking structure, the operator can easily lock the button 3 to avoid the dust cover 5 from being separated from the plug 2 due to the button 3 being pressed, which is more stable.

[0038] Furthermore, if Figure 1 and Figure 7 As shown, a mounting seat 51 is further provided at the bottom of the gun body 1, and an oblong guide hole 52 is penetrated through the mounting seat 51, and two spaced-apart movable arms 53 are provided at the bottom of the dust cover 5, and a connecting rod 54 is threadedly connected between the ends of the movable arms 53, and the connecting rod 54 is movably arranged in the guide hole 52. The movable arm 53 moves horizontally in the guide hole 52 through the connecting rod 54 to drive the dust cover 5 to move horizontally relative to the mounting seat 51. When the dust cover 5 moves to be separated from the plug 2, the movable arm 53 can also rotate in the guide hole 52 through the connecting rod 54 to drive the dust cover 5 to flip downward, so that the plug 2 is exposed to the outside.

[0039] Furthermore, a snap-fit ​​hole 15 is provided on the gun body 1, and a snap-fit ​​head 57 is provided on the dust cover 5. After the dust cover 5 is detached from the plug 2 and rotated downward, it can continue to move along the mounting seat 51 and allow the snap-fit ​​head 57 to snap into the snap-fit ​​hole 15 to fix the dust cover 5, which is suitable for when the gun body 1 is in a charging state; a second pushing portion 55 is also provided at the bottom of the dust cover 5, and a plurality of groove-like structures are provided on the second pushing portion 55. Similarly, the operator can quickly move the dust cover 5 by pressing the second pushing portion 55.

[0040] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
