Description

Technical Field

[0001] This application relates to the field of charging pile technology, and more specifically, to a charging pile locking structure and a charging pile. Background Technology

[0002] When using charging stations or car charging, the charging gun with the cable needs to be placed on the charging gun socket for charging or storage. After the car is finished charging, the user unplugs the charging gun from the car's socket and inserts it back into the charging gun socket of the charging station using the locking buckle on the charging gun.

[0003] However, the existing charging gun holder and charging gun head mating structure has significant flaws. The clip in the gun stock uses a fixed structure, requiring the user to tilt the gun head downwards at a specific angle to insert it into the gun stock, and then rely on the gun head's upward tilt under gravity to engage the clip. This operation requires extremely precise angle control; in actual use, if the insertion angle is slightly off, the charging gun head is difficult to hook, and users often need to try multiple times to successfully hook the gun. This not only reduces the efficiency of charging gun storage but also provides a poor user experience. Furthermore, frequent attempts to hook the gun may increase wear on the charging gun head and gun stock, shorten the equipment's lifespan, and affect the overall performance and reliability of the charging station. Utility Model Content

[0004] The purpose of this application is to provide a charging pile locking structure and a charging pile, which can improve the storage stability of the charging pile.

[0005] The embodiments of this application are implemented as follows:

[0006] One aspect of this application provides a charging pile locking structure, including a gun holder and a gun head. The gun holder has a receiving cavity for accommodating the gun head. A locking structure is provided on the gun holder. The locking structure includes a lock body and a latch slidably disposed in the lock body. The gun head is provided with a lock groove. The gun head has a locked position and an unlocked position in the receiving cavity. When the gun head extends into the receiving cavity and is located in the locked position, the latch slides relative to the lock body and engages with the lock groove. When the gun head rotates from the locked position to the unlocked position, the gun head drives the latch to retract towards the lock body to disengage from the lock groove.

[0007] Optionally, as an implementable method, the latch is provided with adjacent first and second guide ramps. During the process of the gun head extending into the receiving cavity and being in the locked position, the gun head guides the latch head to retract towards the lock body via the first guide ramp. When the gun head is in the locked position, the latch head extends relative to the lock body and engages with the lock groove. During the process of the gun head rotating from the locked position to the unlocked position within the receiving cavity, the gun head guides the latch head to retract towards the lock body via the second guide ramp, so that the latch head disengages from the lock groove.

[0008] Optionally, as an implementable method, a spring is provided in the lock body, one end of the spring being connected to the lock body and the other end being connected to the bolt.

[0009] Optionally, as one possible implementation, the latch includes a connecting section and a snap-fit ​​section, with the first guide ramp and the second guide ramp disposed in the snap-fit ​​section, and the connecting section connected to the spring.

[0010] Optionally, as an implementable method, a limiting part is provided in the lock body, and the end of the connecting section away from the locking section cooperates with the limiting part.

[0011] Optionally, as an implementable method, the gun head has a supporting plate, and a limiting step is provided on the opening side of the receiving cavity, with the supporting plate abutting against the limiting step.

[0012] Optionally, as an implementable method, the lock body is provided with guide ribs that extend along the sliding direction of the bolt, and the bolt is provided with guide grooves corresponding to the guide ribs.

[0013] Alternatively, as an implementable method, both the first guide ramp and the second guide ramp are curved surfaces.

[0014] Optionally, as an implementable method, the opening side of the receiving cavity has a locking mark corresponding to the locking position and an unlocking mark corresponding to the unlocking position.

[0015] In another aspect of the embodiments of this application, a charging pile is provided, including a pile body and a charging pile locking structure as described in any of the above.

[0016] The beneficial effects of the embodiments of this application include:

[0017] The charging pile locking structure and charging pile provided in this application include a gun holder and a gun head. The gun holder has a cavity for accommodating the gun head and a locking structure is provided on the gun holder. The locking structure includes a lock body and a locking tongue slidably disposed within the lock body. The gun head has a locking groove and has a locked position and an unlocked position within the cavity. When the gun head is inserted into the cavity and is in the locked position, the locking tongue slides relative to the lock body and engages with the locking groove. When the gun head rotates from the locked position to the unlocked position, the gun head drives the locking tongue to retract towards the lock body to disengage from the locking groove. Locking and unlocking are achieved by changing the position of the gun head within the cavity. Users do not need to precisely control the insertion angle of the gun head; they only need to insert the gun head into the cavity until it reaches the locked position for automatic locking, greatly reducing the difficulty of operation, improving the efficiency of charging gun storage, and providing users with a more convenient and smooth user experience. It reduces ineffective operations and friction during the gun hanging process, effectively extending the service life of the charging gun head and gun stock, thereby improving the overall performance and reliability of the charging pile.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a charging pile locking structure 100, including a gun holder 110 and a gun head 120. The gun holder 110 has a receiving cavity for accommodating the gun head 120. A locking structure 130 is provided on the gun holder 110. The locking structure 130 includes a lock body 131 and a locking tongue 132 slidably disposed in the lock body 131. A locking groove 121 is provided on the gun head 120. The gun head 120 has a locking position and an unlocking position in the receiving cavity. When the gun head 120 extends into the receiving cavity and is in the locking position, the locking tongue 132 slides relative to the lock body 131 and then engages with the locking groove 121. When the gun head 120 rotates from the locking position to the unlocking position, the gun head drives the locking tongue 132 to retract toward the lock body 131 to disengage from the locking groove 121.

[0030] When using the charging pile locking structure 100 of this application, when it is necessary to hang the charging head 120 into the charging head holder 110, the charging head 120 is aligned with the locking position of the receiving cavity of the charging head holder 110 and inserted. During insertion, the charging head 120 presses against the locking tongue 132, causing the locking tongue 132 to retract into the lock body 131. When the charging head 120 reaches the locking position, the locking tongue 132 extends relative to the lock body 131 and engages with the locking groove 121 on the charging head 120, thereby locking the charging head 120. When it is necessary to remove the charging head 120, the charging head 120 is rotated from the locking position to the unlocking position, and the locking tongue 132 retracts into the lock body 131 to disengage from the locking groove 121, thereby unlocking the charging head 120.

[0031] The charging pile locking structure 100 provided in this application includes a gun holder 110 and a gun head 120. The gun holder 110 has a receiving cavity for accommodating the gun head 120. A locking structure 130 is provided on the gun holder 110. The locking structure 130 includes a lock body 131 and a locking tongue 132 slidably disposed in the lock body 131. A locking groove 121 is provided on the gun head 120. The gun head 120 has a locking position and an unlocking position in the receiving cavity. When the gun head 120 is inserted into the receiving cavity in the locking position, the locking tongue 132 slides relative to the lock body 131 and then engages with the locking groove 121. When the gun head 120 rotates from the locking position to the unlocking position in the receiving cavity, the locking tongue 132 retracts towards the lock body 131 to disengage from the locking groove 121. Locking and unlocking are achieved by changing the position of the gun head 120 in the receiving cavity. Users do not need to precisely control the insertion angle of the charging gun head 120; they only need to insert the charging gun head 120 into the receiving cavity until it reaches the locking position for automatic locking. This greatly reduces the difficulty of operation, improves the efficiency of charging gun storage, and brings users a more convenient and smooth user experience. It reduces unnecessary operations and friction during the gun hanging process, effectively extending the service life of the charging gun head 120 and the gun stock, thereby improving the overall performance and reliability of the charging pile.

[0032] In one possible embodiment of this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the latch 132 is provided with a first guide slope 1321 and a second guide slope 1322 adjacent to each other. During the process of the gun head 120 extending into the receiving cavity and being in the locked position, the gun head 120 guides the latch 132 to retract toward the lock body 131 via the first guide slope 1321. When the gun head 120 is in the locked position, the latch 132 extends relative to the lock body 131 and is engaged with the lock groove 121. During the process of the gun head 120 rotating from the locked position to the unlocked position in the receiving cavity, the gun head 120 guides the latch 132 to retract toward the lock body 131 via the second guide slope 1322, so that the latch 132 disengages from the lock groove 121.

[0033] Specifically, when the user inserts the nozzle 120 into the receiving cavity, the nozzle 120 first contacts the first guide slope 1321. Under the action of the insertion force, the nozzle 120 pushes the bolt 132 along the first guide slope 1321 to slide into the lock body 131 until the nozzle 120 reaches the locked position, at which point the bolt 132 is engaged in the lock groove 121. When unlocking is required, the nozzle 120 is rotated, and the lock groove 121 contacts the second guide slope 1322. During the rotation, the second guide slope 1322 guides the bolt 132 to retract towards the lock body 131, causing the bolt 132 to disengage from the lock groove 121, making it easier to remove the nozzle 120. By setting the first guide slope 1321 and the second guide slope 1322, a clear guide is provided for the sliding of the locking tongue 132 during the insertion and rotation unlocking process of the gun head 120, making the locking tongue 132 and the locking groove 121 more smoothly, reducing the jamming phenomenon caused by poor cooperation, and improving the smoothness of the operation of the locking structure.

[0034] In one possible embodiment of this application, such as Figure 2 As shown, a spring 133 is provided inside the lock body 131. One end of the spring 133 is connected to the lock body 131, and the other end is connected to the bolt 132.

[0035] Specifically, spring 133 provides elastic restoring force to the locking tongue 132. When the charging head 120 is inserted into the receiving cavity and the locking tongue 132 retracts, spring 133 is compressed and stores elastic potential energy. When the charging head 120 reaches the locked position, spring 133 releases its elastic potential energy, pushing the locking tongue 132 out and engaging with the locking groove 121, thus reliably locking the charging head 120. During unlocking, spring 133 assists in the retraction of the locking tongue 132, ensuring that the locking tongue 132 smoothly disengages from the locking groove 121. Spring 133 provides a stable and continuous elastic restoring force to the locking tongue 132, ensuring a reliable holding force between the locking tongue 132 and the locking groove 121, preventing the charging head 120 from accidentally falling off during use, and improving the safety of the charging gun placement.

[0036] In one possible embodiment of this application, such as Figure 2 As shown, the locking tongue 132 includes a connecting section and a snap-fit ​​section. The first guide slope 1321 and the second guide slope 1322 are disposed in the snap-fit ​​section, and the connecting section is connected to the spring 133.

[0037] Specifically, the connecting section is used to connect the locking tongue 132 and the spring 133, and to transmit the force of the spring 133 during the sliding of the locking tongue 132; the snap-fit ​​section, by setting the first guide slope 1321 and the second guide slope 1322, cooperates with the gun head 120 and the lock groove 121 to complete the locking and unlocking functions.

[0038] In one possible embodiment of this application, such as Figure 2As shown, a limiting part is provided inside the lock body 131, and the end of the connecting section away from the locking section cooperates with the limiting part.

[0039] Specifically, by setting a limiting part, the limiting part restricts the sliding of the lock tongue 132 during the process of the spring 133 pushing the lock tongue 132 out and into the lock groove 121, so as to ensure that the lock tongue 132 moves within a reasonable range of stroke.

[0040] In one possible embodiment of this application, such as Figure 1 and Figure 2 As shown, the gun head 120 has a supporting plate 122, and a limiting step 111 is provided on the opening side of the accommodating cavity. The supporting plate 122 abuts against the limiting step 111.

[0041] Specifically, when the gun head 120 is inserted into the receiving cavity and reaches the locking position, the abutment plate 122 contacts and abuts against the limiting step 111. Through the cooperation of the abutment plate 122 and the limiting step 111, the insertion depth of the gun head 120 in the receiving cavity is limited, ensuring that the gun head 120 is in the correct locking position, while providing support and positioning for the gun head 120.

[0042] In one possible embodiment of this application, such as Figure 2 As shown, the lock body 131 is provided with guide ribs, which extend along the sliding direction of the latch 132, and the latch 132 is provided with guide grooves corresponding to the guide ribs.

[0043] The cooperation between the guide rib and the guide groove provides precise guidance for the sliding of the locking tongue 132, effectively reducing the offset and wobbling of the locking tongue 132 during the sliding process. This allows the locking tongue 132 to accurately engage with the gun head 120 and the locking groove 121, improving the accuracy and reliability of the locking structure. The cooperation between the guide rib and the guide groove is simple and intuitive, facilitating installation and adjustment during assembly, reducing assembly difficulty, improving production efficiency, and also helping to ensure the assembly quality of the product.

[0044] In one possible embodiment of this application, such as Figure 4 As shown, both the first guide slope 1321 and the second guide slope 1322 are curved surfaces.

[0045] Compared to a flat, inclined surface, the curved surface better matches the gun head 120 and the locking groove 121. During the insertion and unlocking of the gun head 120, the guiding effect of the curved surface is gentler, resulting in less resistance felt by the user during operation, making the operation easier and smoother, and improving the user experience. This makes hanging and retrieving the gun more comfortable and convenient. The curved surface can better adapt to the angle changes during the insertion and rotation of the gun head 120. Even if there is a certain angle deviation during operation, the curved surface can still ensure a good guiding effect, improving the adaptability and reliability of the locking structure to different operating conditions.

[0046] In one possible embodiment of this application, such as Figure 5 As shown, the opening side of the accommodating cavity has a locking mark 112 corresponding to the locking position and an unlocking mark 113 corresponding to the unlocking position.

[0047] Specifically, the locking indicator 112 and the unlocking indicator 113 are used to visually indicate to the user the locking and unlocking positions of the gun head 120 within the accommodating cavity, helping the user to operate correctly and avoid locking or unlocking failures due to improper operation.

[0048] This application also discloses a charging pile, including a pile body and the charging pile locking structure 100 in the foregoing embodiments. This charging pile has the same structure and beneficial effects as the charging pile locking structure 100 in the foregoing embodiments. The structure and beneficial effects of the charging pile locking structure 100 have been described in detail in the foregoing embodiments and will not be repeated here.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
