Description
Technical Field
[0001] This utility model relates to the technical field of adapters for charging guns and charging sockets, specifically an adapter with a reverse insertion timing protection mechanism. Background Technology
[0002] With increasing environmental awareness, new energy vehicles are becoming more widely used due to their advantages of not requiring fuel and being safe and environmentally friendly. These vehicles rely on electric power and need to be charged at specific charging stations using a charging gun connected to the charging station via a cable. However, with the development of the new energy vehicle industry, different countries and regions have formulated their own different charging interface standards, which often results in the vehicle socket and the charging gun being incompatible, causing inconvenience to vehicle charging. To solve this problem, a charging gun adapter is needed.
[0003] A charging adapter is a device used to connect charging interfaces of different specifications, enabling compatibility between charging equipment and power sources or vehicles. In terms of electrical connection, it enables physical docking between interfaces of different specifications, resolving connection problems caused by differences in interface shape and size, and establishing a stable physical path for previously incompatible devices. Regarding signal conversion, it can convert electrical signals under different standards, including adjusting parameters such as voltage, current, and frequency, ensuring accurate signal transmission and recognition between different devices. In terms of compatibility expansion, it breaks down barriers between devices caused by different interface and signal standards, allowing devices of different brands and models to work together, improving device versatility and utilization. Furthermore, the adapter provides certain protection functions, such as overcurrent and overvoltage protection, preventing damage to connected devices due to abnormal electrical conditions and ensuring safe and stable operation.
[0004] The existing adapter can be inserted into the vehicle body first and then into the gun body, or the gun body can be inserted first and then both can be inserted into the vehicle body. This does not meet the customer's requirement for the correct insertion and removal sequence. The normal sequence should be to insert the gun body first and then into the vehicle body. When inserting and removing in reverse, the spring is compressed too much, which can easily damage the spring. In addition, there is a risk of leakage when inserting and removing in reverse, which also poses a certain danger to people when using it. Utility Model Content
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an adapter with a reverse insertion timing protection mechanism. This solves the problem that the adapter can be inserted into the vehicle body first and then into the gun body, or the gun body can be inserted first and then both can be inserted into the vehicle body. This allows for both forward and reverse insertion, which does not meet the customer's requirement for the correct insertion and removal sequence. The normal sequence should be to insert the gun body first and then into the vehicle body. When inserting and removing the adapter in the reverse direction, the spring is compressed too much, which can easily damage the spring. Furthermore, there is a risk of leakage when inserting and removing the adapter in the reverse direction, which also poses a certain degree of danger to users.
[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an adapter with a reverse insertion timing protection mechanism, comprising an adapter body, a vehicle body insertion end on one side of the adapter body, a charging gun insertion end on the other side of the adapter body, an unlocking button on the top of the adapter body, a reverse insertion mechanism on the inner top side of the adapter body located below the button, the reverse insertion mechanism including a feedback post slidably connected to the inner side of the adapter body, one end of the feedback post extending to the outside of the adapter body, anti-misalignment pins provided on both sides of the feedback post and the inner wall of the adapter body, and a locking mechanism inside the adapter body, wherein one end of the locking mechanism... The end is snapped into the inside of the feedback column. The locking mechanism is located on the top side of the anti-fool pin. A pressing port is provided on the top of the locking mechanism. The bottom end of the unlocking button passes through the pressing port and extends to the bottom side of the locking mechanism. A spring is sleeved between the feedback column and the locking mechanism. In this invention, when using the adapter body, the charging gun is first inserted into the charging gun insertion end on the adapter body, and then the vehicle body insertion end on the adapter body is inserted into the vehicle body socket for charging. After charging is completed, the adapter body is first pulled out of the vehicle body socket, and then the charging gun is pulled out of the adapter body. During use, the anti-reverse insertion mechanism provides protection, ensuring that people use it in the correct order, guaranteeing safety during use, and extending the service life of the spring in the adapter body.
[0007] Preferably, the spring is sleeved on the outside of the lock, and one end of the spring is sleeved inside the feedback post.
[0008] Preferably, the feedback column has track grooves on both sides, and the track grooves are located inside the adapter body.
[0009] Preferably, a slider is fixedly connected to the surface of the anti-fool pin, the slider is slidably connected to the inside of the track groove, and one side of the anti-fool pin is rotatably connected to the inner wall of the adapter body. In this invention, by moving the slider forward and backward in the track groove, one side of the anti-fool pin can rotate upward or downward, thereby enabling the anti-fool pin to engage or disengage from the locking mechanism, thus enabling the determination of whether the unlock button can be pressed and whether the charging gun hook can be inserted into or removed from the adapter body.
[0010] Preferably, a charging gun hook is attached to one side of the adapter body. The charging gun hook is located on the side near the insertion end of the charging gun and on the locking side. In this invention, after the charging gun is inserted into the adapter body, the charging gun hook can hook the charging gun and the adapter body together, preventing the charging gun from being accidentally pulled out during charging and causing danger.
[0011] Preferably, one side of the feedback column abuts against the vehicle body charging port flange, which is located near the vehicle body insertion end. In this invention, the vehicle body charging port flange can abut against the feedback column to move left and right, and the surface of the feedback column is provided with a track groove. When the adapter body is plugged in or unplugged from the vehicle body, the slider slides on the track groove, and the movement of the feedback column can cause the anti-fool pin to rise or fall, thereby enabling the anti-fool pin to engage or disengage from the locking mechanism.
[0012] (III) Beneficial Effects This utility model provides an adapter with a reverse insertion timing protection mechanism. It has the following beneficial effects: (i) The adapter with anti-reverse insertion timing protection mechanism, through the setting of the anti-reverse insertion mechanism, makes the feedback post contact the vehicle body and move backward when it is inserted into the vehicle body first, causing the slide and anti-fool pin to rise, preventing the charging gun hook at the charging gun end from moving forward, thereby preventing the charging gun from being inserted, playing the role of preventing reverse insertion, meeting people's needs for the adapter to be inserted in the correct direction, and extending the life of the internal spring of the adapter, as well as reducing the risk of leakage when reverse insertion and removal, and improving the safety of the charging gun during the charging process.
[0013] (ii) The adapter with anti-reverse insertion timing protection mechanism, through the setting of the locking and charging gun hook, can make the charging gun inserted more securely when charging through the adapter, preventing the charging gun from being pulled out of the adapter during the charging process, thus improving the safety of the adapter during use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] See Figure 1-7 This utility model provides a technical solution: an adapter with a reverse insertion timing protection mechanism, the structure of which includes an adapter body 1, a vehicle body insertion end 2 on one side of the adapter body 1, a charging gun insertion end 3 on the other side of the adapter body 1, an unlocking button 4 on the top of the adapter body 1, a reverse insertion mechanism 5 on the inner top side of the adapter body 1, the reverse insertion mechanism 5 being located below the button 4, the reverse insertion mechanism 5 including a feedback post 51, the feedback post 51 being slidably connected to the inner side of the adapter body 1, one end of the feedback post 51 extending to the outside of the adapter body 1, anti-foolproof pins 52 being provided on both sides of the feedback post 51 and the inner wall of the adapter body 1, and a locking lock 53 being provided inside the adapter body 1, one end of the locking lock 53 being engaged with the inner side of the feedback post 51. The locking mechanism 53 is located on the top side of the anti-fooling pin 52. A pressing port 54 is provided on the top of the locking mechanism 53. The bottom end of the unlocking button 4 passes through the pressing port 54 and extends to the bottom side of the locking mechanism 53. A spring 55 is sleeved between the feedback post 51 and the locking mechanism 53. Specifically, when using the adapter body 1, first insert the charging gun into the charging gun insertion end 3 on the adapter body 1, and then insert the vehicle body insertion end 2 on the adapter body 1 into the vehicle body socket for charging. After charging is completed, first pull the adapter body 1 out of the vehicle body socket, and then pull the charging gun out of the adapter body 1. During use, the anti-reverse insertion mechanism 5 provides protection, ensuring that people use it in the correct order, guaranteeing safety during use, and extending the service life of the spring 55 in the adapter body 1.
[0018] The spring 55 is sleeved on the outside of the lock 53, and one end of the spring 55 is sleeved inside the feedback post 51.
[0019] The feedback column 51 has track grooves 56 on both sides, and the track grooves 56 are located inside the adapter body 1.
[0020] The surface of the anti-fool pin 52 is fixedly connected to a slider 57, which is slidably connected to the inside of the track groove 56. One side of the anti-fool pin 52 is rotatably connected to the inner wall of the adapter body 1. Specifically, by moving the slider 57 in the forward and reverse directions in the track groove 56, one side of the anti-fool pin 52 can rotate up or down, thereby enabling the anti-fool pin 52 to engage or disengage from the lock 53. This allows the unlock button 4 to be pressed and the charging gun hook 6 to be inserted into or removed from the adapter body 1.
[0021] The adapter body 1 has a charging gun hook 6 attached to one side. The charging gun hook 6 is located on the side near the charging gun insertion end 3 and on the side of the lock 53. Specifically, after the charging gun is inserted into the adapter body 1, the charging gun hook 6 can hook the charging gun and the adapter body 1 together to prevent the charging gun from being accidentally pulled out during charging and causing danger.
[0022] The feedback post 51 has a body charging port flange 7 on one side, which is located near the body insertion end 2. Specifically, the body charging port flange 7 can move left and right against the feedback post 51. The surface of the feedback post 51 is provided with a track groove 56. When the adapter body 1 is plugged in or unplugged from the body, the slider 57 slides on the track groove 56. The movement of the feedback post 51 can cause the anti-fool pin 52 to rise or fall, thereby enabling the anti-fool pin 52 to engage or disengage from the lock 53.
[0023] Working principle: When the adapter is inserted in the normal order, that is, the charging gun is inserted first and then the adapter and the charging gun are inserted into the vehicle socket. At this time, there is no engagement between the anti-misalignment pin 52 and the locking pin 53. When the charging gun is inserted into the charging gun insertion end 3, the charging gun hook 6 can resist the movement of the locking pin 53 and engage with the inside of the adapter body 1. Then the adapter body 1 is inserted into the vehicle charging socket. When the vehicle insertion end 2 is inserted into the vehicle charging socket, the slider 57 slides relative to the track groove 56 on the feedback post 51, so that one end of the anti-misalignment pin 52 rotates and rises until the feedback post 51 moves to the innermost position. At this time, the anti-misalignment pin 52 locks the locking pin 53 and the locking pin 53 cannot move, so the unlock button 4 cannot be pressed down. When the adapter is pulled out in the normal order, that is, the adapter body 1 is pulled out of the vehicle body first and then the charging gun is pulled out. When the adapter body 1 is pulled out of the vehicle body, the feedback post 51 gradually moves outward, and at the same time the slider 57 slides in the opposite direction in the track groove 56. When the adapter is completely pulled out of the vehicle body, the feedback post 51 moves to the outermost position and the slider 57 moves to the rightmost position of the track groove 56. As a result, the anti-fool pin 52 rotates in the opposite direction and descends. At this time, the anti-fool pin 52 is disengaged from the lock 53, and the lock 53 can move left and right. Press the unlock button 4 down and the lock 53 moves to the left, so that the charging gun hook 6 can be removed from the adapter body 1, that is, the charging gun can be removed from the adapter body 1. When the adapter is inserted in an abnormal order, i.e., the adapter is inserted into the vehicle body first and then the charging gun is inserted into the adapter, the feedback post 51 is pushed into the adapter by the vehicle body charging port flange 7, thereby the anti-fouling pin 52 rotates open and pushes against the lock 53. At this time, the lock 53 is fixed and cannot be moved, so the unlock button 4 cannot be pressed, and the charging gun hook 6 cannot push the lock 53 and engage with the adapter body 1. That is, the charging gun cannot continue to be pushed and inserted into the adapter body 1. When the adapter is pulled out in an abnormal order, i.e., the charging gun is pulled out first and then the adapter body 1 is pulled out from the vehicle body socket, the anti-fooling pin 52 and the locking pin 53 are locked together by rotation, so the unlocking button 4 cannot be pressed, and the charging gun hook 6 cannot move against the locking pin 53 and be pulled out. As a result, the charging gun cannot be removed from the adapter body 1 first.
