Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle charging device technology, and in particular to an automatic locking gun structure and a charging converter. Background Technology

[0002] A Chinese utility model patent with patent number ZL202421939280.8 and patent title "A Charging Adapter" discloses the following technical solution: A charging adapter includes a main body. One end of the main body has a first cavity that connects to a charging gun on a charging pile. The end of the main body away from the first cavity has two second cavities that connect to the charging head of a battery in a new energy vehicle. An adjustment cavity is provided at the end of the main body near the first cavity. A retaining block is slidably installed in a first sliding hole connecting the adjustment cavity and the first cavity. The two ends of the retaining block extend into the corresponding adjustment cavity and the first cavity, respectively. An adjustment mechanism is provided on the main body. The adjustment mechanism includes a first spring that abuts against a retaining block. When the charging gun enters the first cavity, the charging gun abuts against the retaining block, causing the first spring to compress. Two second sliding holes communicating with the adjustment cavity are opened at one end of the main body near the second cavity. An adjustment assembly is provided on the main body. The adjustment assembly includes an adjustment rod, an adjustment plate, a push rod, and an adjustment block slidably installed in the adjustment cavity, which are connected in sequence. A second spring is sleeved on the push rod, and the adjustment block is connected to the push rod. A limiting block is provided on the adjustment block. The adjustment block is also equipped with a reset assembly, which includes a connecting block integrally formed with the adjustment block. A reset block is fixedly connected to the end of the connecting block away from the adjustment block.

[0003] When the aforementioned charging adapter is in use, if the main body is not connected to the charging head of the new energy vehicle, the second spring is in an extended state and the adjusting rod extends away from the adjusting block. When the charging gun is located in the first cavity of the main body and the clamping block remains in contact with the charging gun, the main body is then connected to the charging head of the new energy vehicle. When the main body is connected to the charging head, the adjusting rod will contact the vehicle body. At this time, the adjusting component moves and the second spring is compressed. The adjusting block drives the limiting block to move closer to the clamping block, and finally makes the limiting block contact the clamping block. At this time, the clamping block locks the charging gun. After charging is completed, pull out the main body or the charging gun to separate the main body from the charging head. Then move the reset block. The reset block drives the connecting block to move. The connecting block drives the adjusting block to move away from the lifting block, so that the limiting block on the adjusting block separates from the clamping block. Finally, pull out the charging gun to separate the charging gun from the first cavity on the main body.

[0004] It should be noted that the above-mentioned charging adapter has the following defects: Specifically, the locking structure is composed of a retaining block, a first spring, an adjusting rod, an adjusting plate, an adjusting block, a limiting block, a second spring, a connecting block, and a reset block. When locking the charging gun, the adjusting rod, adjusting plate, adjusting block, and limiting block move towards the retaining block, causing the limiting block to abut against the retaining block, thereby locking the charging gun in the first cavity. After charging is completed, the reset block and connecting block are moved to reset the adjusting block, thereby eliminating the limiting effect of the limiting block. At this time, the locking of the charging gun is released. The overall structure of the above-mentioned locking structure is complex and requires manual operation to move the reset block. Because it cannot achieve automatic reset, the ease of use is poor. Utility Model Content

Detailed Implementation

[0042] The present invention will now be described in conjunction with specific embodiments.

[0043] Example 1, as Figures 1 to 4 As shown, an automatic locking gun structure is applied to a charging converter 1. The charging converter 1 includes a converter body 2. The converter body 2 has a first cavity 21 for inserting a charging gun 7 and a second cavity 22 for inserting a new energy vehicle charging socket. The first cavity 21 is located at the rear end of the converter body 2, and the second cavity 22 is located at the front end of the converter body 2.

[0044] Among them, such as Figures 2 to 6 As shown, the automatic gun locking structure includes a gun locking slider 3, a sliding member 4, and a return spring 5 that elastically pushes the sliding member 4 toward the second cavity 22. The gun locking slider 3 and the sliding member 4 are slidably mounted on the converter body 2, and the sliding direction of the gun locking slider 3 is perpendicular to the sliding direction of the sliding member 4. The sliding member 4 is provided with a straight rod part 41 that extends into the second cavity 22.

[0045] Furthermore, such as Figure 3 and Figure 4 As shown, a slider drive unit 42 is provided at the rear end of the slider 4, and the locking gun slider 3 is movably mounted on the slider drive unit 42 of the slider 4; when the slider 4 moves backward relative to the converter body 2, the slider 4 drives the locking gun slider 3 to move toward the first cavity 21 side through the slider drive unit 42; when the slider 4 moves forward relative to the converter body 2, the slider 4 drives the locking gun slider 3 to move away from the first cavity 21 through the slider drive unit 42.

[0046] Specifically, such as Figure 3 and Figure 4 As shown, the locking gun slider 3 has an oblique hole 31 corresponding to the sliding member 4, and the slider driving part 42 is provided with an inclined section 421. The inclined section 421 of the slider driving part 42 is slidably inserted into the oblique hole 31 of the locking gun slider 3. When the sliding member 4 slides back and forth relative to the converter body 2, the inclined section 421 of the slider driving part 42 of the sliding member 4 cooperates with the oblique hole 31 of the locking gun slider 3, and the inclined section 421 of the slider driving part 42 drives the locking gun slider 3 to move relatively closer to or away from the first cavity 21.

[0047] The automatic locking gun structure of this embodiment will be described in detail below using the NACS standard charging gun 7 to a US standard CCS1 car charger for new energy vehicles as an example. Specifically: During charging, the NACS standard charging gun 7 is first inserted into the first cavity 21 of the converter body 2. When the NACS standard charging gun 7 is inserted in place, the locking groove 71 of the NACS standard charging gun 7 is aligned with the locking slider 3. At this time, the straight rod 41 of the sliding member 4 extends into the second cavity 22 and the return spring 5 is in the extended state. After the NACS standard charging gun 7 is inserted into the first cavity 21, the second cavity 22 of the converter body 2 is aligned with the US standard CCS1 car charger, and the US standard CCS1 car charger is inserted into the second cavity 22 of the converter body 2. During this process, the CCS1 standard car charger will abut against the straight rod 41 of the slider 4 towards the first cavity 21, causing the slider 4 to move towards the first cavity 21. As the slider 4 moves backward, the return spring 5 is compressed, and the slider 4 drives the locking slider 3 towards the first cavity 21 via the slider drive part 42, ultimately causing the locking slider 3 to insert into the locking groove 71 of the NACS standard charging gun 7, thereby locking and fixing the NACS standard charging gun 7 within the first cavity 21 of the converter body 2. When charging is completed and the NACS standard charging gun 7 is unlocked, because the locking slider 3 locks the NACS standard charging gun 7, the converter body 2 and the NACS standard charging gun 7 move synchronously and retract from the CCS1 standard car charger of the new energy vehicle.

[0048] During this process, the reset force of the reset spring 5 causes the slider 4 to move toward the second cavity 22. The straight rod part 41 of the slider 4 re-enters the second cavity 22. As the slider 4 moves forward relative to the converter body 2, the slider drive part 42 of the slider 4 drives the locking slider 3 to move away from the first cavity 21, and causes the locking slider 3 to gradually exit the locking groove 71 of the NACS standard charging gun 7. When the locking slider 3 completely exits the locking groove 71 of the NACS standard charging gun 7, the locking effect of the locking slider 3 on the NACS standard charging gun 7 is released, and the NACS standard charging gun 7 can be pulled out from the first cavity 21 of the converter body 2. This can effectively avoid the risk of pulling out the gun while it is energized during high voltage charging.

[0049] It should be emphasized that the automatic gun locking structure of this embodiment includes a sliding member 4, a return spring 5, and a gun locking slider 3, and the sliding member 4 and the gun locking slider 3 are linked together; compared with the prior art, the overall structure of the automatic gun locking structure of this embodiment is simpler.

[0050] In addition, when the converter body 2 is removed from the charging socket of the new energy vehicle, the sliding member 4 automatically moves towards the second cavity 22 under the action of the reset spring 5, thereby causing the locking gun slider 3 to move automatically and retract from the charging gun 7; compared with the prior art, the automatic locking gun structure of this embodiment is more convenient to operate and use.

[0051] In summary, the automatic gun locking structure of this embodiment has the advantages of novel design, simple structure, and convenient operation through the above structural design.

[0052] Example 2, as Figures 3 to 6 As shown, the difference between this embodiment 2 and embodiment 1 is that the converter body 2 is equipped with a locking gun auxiliary block 6, and the sliding member 4 includes a base 43 located between the slider driving part 42 and the straight rod part 41.

[0053] The base 43 of the sliding member 4 is slidably mounted on the gun locking auxiliary block 6, and the return spring 5 is installed between the gun locking auxiliary block 6 and the base 43 of the sliding member 4. The front end of the return spring 5 abuts against the base 43 of the sliding member 4, and the rear end of the return spring 5 abuts against the gun locking auxiliary block 6.

[0054] Example 3, as Figure 3 and Figure 4 As shown, the difference between this embodiment 3 and embodiment 2 is that: the locking gun auxiliary block 6 has an auxiliary block through hole 61 for the locking gun slider 3 to pass through, and the converter body 2 has a main body through hole 23 that communicates with the first cavity 21 and is aligned with the auxiliary block through hole 61; when the charging gun 7 is inserted into the first cavity 21, the locking groove 71 of the charging gun 7 is aligned with the main body through hole 23.

[0056] The sidewall of the slide groove 62 is provided with a guide groove 63 corresponding to the sliding member 4, and the base 43 of the sliding member 4 is provided with a guide post 431 corresponding to the guide groove 63. The guide post 431 of the sliding member 4 extends into the guide groove 63.

[0057] During the sliding motion of the slider 4 relative to the converter body 2, in this embodiment, the guide groove 63 of the locking gun auxiliary block 6 cooperates with the guide post 431 of the slider 4 to guide the slider 4 to move accurately, so as to improve the stability of the sliding motion of the slider 4.

[0058] Example 5, as Figure 5 and Figure 6 As shown, the difference between this embodiment 5 and embodiment 4 is that: the locking gun auxiliary block 6 has a spring positioning cavity 64 on the side of the slide groove 62, and the spring positioning cavity 64 is connected to the slide groove 62.

[0059] The reset spring 5 is positioned and installed in the spring positioning cavity 64, and the base 43 of the sliding member 4 is provided with a protrusion 432 that extends into the spring positioning cavity 64. The front end of the reset spring 5 abuts against the protrusion 432.

[0060] In this embodiment, the reset spring 5 is positioned by the spring positioning cavity 64, which can effectively improve the convenience of installing the reset spring 5 and effectively improve the stability of the reset spring 5 during operation.

[0061] Example 6, as Figure 3 and Figure 4 As shown, the difference between this sixth embodiment and the first embodiment is that the straight rod portion 41 of the slider 4 of the converter body 2 is provided with a guide hole 24 that communicates with the second cavity 22, and the straight rod portion 41 of the slider 4 passes through the guide hole 24 of the converter body 2.

[0062] Example 7, as Figures 1 to 4 As shown, a charging converter includes the aforementioned automatic locking gun structure.

[0063] It should be noted that, since the above-mentioned automatic gun locking structure has the advantages of novel design, simple structure and convenient operation, the charging converter 1 of this embodiment 7, which includes the automatic gun locking structure, also has the advantages of novel design, simple structure and convenient operation.

[0064] Example 8, as Figure 7 and Figure 8 As shown, the difference between this embodiment eight and embodiment seven is that the converter body 2 includes a main body shell, the first cavity 21 is disposed at the front end of the main body shell, and the second cavity 22 is disposed at the rear end of the main body shell.

[0065] An insulating bracket 91 is securely installed inside the main body shell. A terminal assembly is securely installed on the insulating bracket 91. The terminal assembly includes a DC+ terminal 921, a DC- terminal 922, an AC L1 terminal 923, and an AC N terminal 924. The DC+ terminal 921 and the DC- terminal 922 are arranged at intervals. The front ends of the DC+ terminal 921 and the DC- terminal 922 extend into the first cavity 21 and are electrically connected to the charging gun 7 during charging. The rear ends of the DC+ terminal 921 and the DC- terminal 922 extend into the second cavity 22.

[0066] In addition, AC N terminal 924 is securely connected to DC DC+ terminal 921 and AC N terminal 924 and DC DC+ terminal 921 are connected in series, AC L1 terminal 923 is securely connected to DC DC- terminal 922 and AC L1 terminal 923 and DC DC- terminal 922 are connected in series.

[0067] It should be explained that the AC N terminal 924 can be fastened to the DC+ terminal 921 by riveting, and similarly, the AC L1 terminal 923 can be fastened to the DC- terminal 922 by riveting.

[0068] Furthermore, the converter body 2 is equipped with a charging switch button 8. The function of the charging switch button 8 in this embodiment eight is as follows: the charging switch button 8 can switch between AC and DC charging. When the charging gun 7 input is AC, the charging switch button 8 can be used to switch to AC charging mode. At this time, an AC signal is input to the charging dock of the new energy vehicle, and the AC L1 terminal 923 and AC N terminal 924 will receive the input of electrical energy. When the charging gun 7 input is DC, the charging switch button 8 can be used to switch to DC charging mode. At this time, a DC signal is input to the charging dock of the new energy vehicle, and the DC+ terminal 921 and DC- terminal 922 will receive the input of electrical energy.

[0069] The charging converter in this embodiment eight can realize both AC charging and DC charging, thus achieving a two-in-one function.
