Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic locks, and in particular to an electronic lock for a new energy vehicle. Background Art
[0002] The locking device of the charging gun of new energy vehicles is indeed usually composed of a mechanical lock and an electronic lock. In the application scenarios of existing electronic locks for new energy vehicles, the state switching of the lock pin plays a vital role. It accurately controls the locking and releasing of the charging gun. However, with the continuous accumulation of usage time, the lock pin will inevitably gradually wear out due to various environmental factors and usage conditions. This wear can easily cause the locking device of the charging gun to appear stuck, abnormal noise and other problems. In severe cases, it may even affect the stability and safety of the charging process. After the above problems occur, the lock pin needs to be replaced, but the lock pin design on the traditional electronic lock is often directly fixed on the output shaft of the motor. Although this design is simple, it brings considerable difficulties when the lock pin needs to be replaced. Due to the close connection between the lock pin and the motor output shaft, the disassembly and assembly work becomes quite cumbersome, which is not only time-consuming and labor-intensive, but may also damage other key components due to improper operation, further increasing the difficulty and cost of maintenance. Summary of the invention
[0003] The disclosed embodiment relates to an electronic lock for a new energy vehicle, which improves the convenience of disassembly of the limit pin block by slidingly installing the limit pin block on the limit slide seat. Compared with the traditional method of directly installing it on the output shaft, the sliding method is more conducive to replacing the worn limit pin block, and when the limit pin block is put into a state of limiting the mechanical lock, the limit pin block can be automatically limited by the limit plug column, thereby improving the stability of the limit pin block when it is put into use. When the limit pin block moves backward and is put into use, the limit pin block will move backward with the transmission push plate and the transmission push column, and when the transmission push column moves backward, it will cooperate with the driven groove and the transmission member to indirectly control the inward movement of the clamping positioning block, so that the clamping positioning block stably clamps the micro switch through the inward movement, thereby improving the stability of the micro switch when it is in use.

[0015] 2. When the limit pin block is in the operating state of limiting the mechanical lock, it will be automatically accurately positioned by the limit plug, thereby ensuring the stability of the limit pin block after it is put into use. This design not only simplifies the operating process, but also greatly improves the overall reliability and durability of the device.

During this process, the transmission push column will cooperate closely with the driven groove and the transmission part, and through clever mechanical linkage, it will indirectly prompt the clamping positioning block to move inward. This movement process ensures that the clamping positioning block can stably and firmly clamp the micro switch, thereby improving the stability and safety of the micro switch in use.

[0023] After the charging gun is mechanically locked into the charging port, the driving motor 3 will rotate with the power conversion screw groove 15. At this time, the power conversion screw groove 15 will use its own semi-helical structure to cooperate with the driven column 18 to move the limiting slide 17, the transmission push plate 19 and the transmission push column 20 backward along the guide column 16. During the backward movement, the transmission push column 20 will use the inclined part of the driven groove 10 to move the transmission member 7 downward, so that the bending structure on the transmission member 7 pushes the inclined surface of the clamping positioning block 12 by descending, so that the clamping positioning block 12 is affected by the inclined surface push and moves inward, thereby realizing the clamping positioning of the micro switch 4.
[0024] Embodiment 2 On the basis of the first embodiment, one end of the restoring spring A9 is embedded and installed at the bottom of the embedded baffle 8; the other end of the restoring spring A9 is embedded and installed at the top of the guide block 6; the top of the transmission member 7 is provided with a bending structure; the front end of the driven groove 10 is an inclined structure; the top outer end of the clamping positioning block 12 is an inclined structure; the bending structure of the transmission member 7 is in contact with the inclined surface of the clamping positioning block 12; one end of the restoring spring B14 is embedded and installed on the inner side of the embedded side plate 13; the other end of the restoring spring B14 is embedded and installed inside the limit block 11; the driven column 18 is also slidably connected with the power conversion screw groove 15; The top of the driven column 18 is a hemispherical structure; the transmission push column 20 is a cylindrical structure; the position of the trigger push column 22 corresponds to the front and rear level of the reed on the micro switch 4; a force-bearing inward displacement groove 26 is provided on the circumferential outer wall of the force-bearing column 25; the inner end of the force-bearing inward displacement groove 26 is an inclined structure; the inclined surface of the force-bearing inward displacement groove 26 corresponds to the front and rear level of the position of the push plate 5; one end of the restoring spring C27 is embedded and installed on the inner side of the force-bearing column 25; the other end of the restoring spring C27 is embedded and installed on the outer wall of the limit slide 17.
[0025] After the limit slide 17 moves backward to a certain position, the push plate 5 will push the inclined surface of the force-bearing inward displacement groove 26, so that the inclined surface of the force-bearing inward displacement groove 26 will move inward with the force-bearing column 25 and the limit plug 24 after being pushed, so that the limit plug 24 is inserted into the interior of the limit plug hole 23, positioning the limit pin block 21, and ensuring the stability of the limit pin block 21 after being put into use.
[0026] Embodiment 3 On the basis of the second embodiment, when the driving motor 3 rotates with the power conversion screw groove 15, the power conversion screw groove 15 will use its own semi-helical structure to cooperate with the driven column 18 to move the limiting slide 17 backward along the guide column 16; when the limiting slide 17 moves backward, the transmission push plate 19 on the limiting slide 17 will move the transmission push column 20 backward; when the transmission push column 20 moves backward, it will use the inclined part of the driven groove 10 to move the transmission member 7 downward; when the transmission member 7 moves downward, The bending structure on the transmission member 7 will push the inclined surface of the clamping positioning block 12; after the limit slide 17 moves backward to a certain position, the push plate 5 will push the inclined surface of the force-bearing inward displacement groove 26; after the inclined surface of the force-bearing inward displacement groove 26 is pushed, it will move inward with the force column 25 and the limit plug 24; after the limit plug 24 moves inward, it will be inserted into the interior of the limit plug hole 23; when the limit slide 17 moves backward with the limit pin block 21, the trigger push column 22 on the limit pin block 21 will push the reed on the micro switch 4.
[0027] When the limit slide 17 moves backward with the limit pin block 21, the trigger push column 22 on the limit pin block 21 will push the reed on the micro-switch 4, so that the micro-switch 4 will energize the charging port and the charging gun to ensure smooth charging. At this time, due to the backward movement of the limit pin block 21, the pressing action of the mechanical lock structure of the charging gun will be blocked by the limit pin block 21, so the mechanical lock cannot be triggered, ensuring that the charging gun will not be accidentally pulled out.
[0028] The working principle of this embodiment: After the charging gun is locked inside the charging port by the mechanical lock, the driving motor 3 will rotate with the power conversion screw groove 15. At this time, the power conversion screw groove 15 will use its own semi-helical structure to cooperate with the driven column 18 to move the limit slide 17, the transmission push plate 19 and the transmission push column 20 backward along the guide column 16. During the backward movement, the transmission push column 20 will use the inclined part of the driven groove 10 to move the transmission member 7 downward, so that the bending structure on the transmission member 7 pushes the inclined surface of the clamping positioning block 12 by descending, so that the clamping positioning block 12 is affected by the inclined surface and moves inward, thereby realizing the clamping positioning of the micro switch 4. After the limit slide 17 moves backward to a certain position, the push plate 5 will push the force-bearing inward displacement groove 26 The inclined surface pushes up, so that the inclined surface of the force-bearing inward displacement groove 26 is pushed up and moves inward with the force-bearing column 25 and the limit plug 24, so that the limit plug 24 is inserted into the interior of the limit plug hole 23, positioning the limit pin block 21, and ensuring the stability of the limit pin block 21 after being put into use. Moreover, when the limit slide 17 moves backward with the limit pin block 21, the trigger push column 22 on the limit pin block 21 will push the reed on the micro-switch 4, so that the micro-switch 4 will energize the charging port and the charging gun to ensure smooth charging. At this time, due to the backward movement of the limit pin block 21, the pressing action of the mechanical lock structure of the charging gun will be blocked by the limit pin block 21, so the mechanical lock cannot be triggered, ensuring that the charging gun will not be accidentally pulled out.
