Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of new energy vehicles, in particular to a new energy vehicle charging anti-falling mechanism. BACKGROUND

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels, adopt new vehicle power devices), and combine advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. Currently, most new energy vehicles on the market use electric energy, i.e. new energy electric vehicles, which are equipped with charging mechanisms that can be charged through charging guns to provide electric energy for the driving motor of the electric vehicle, and the electric energy of the power supply is converted into mechanical energy by the motor.

[0003] During the actual charging process of a new energy vehicle, it is necessary to ensure the stable connection of the charging gun and the charging mechanism during charging to avoid the influence of external forces and the phenomenon of falling off, which may lead to charging interruption or reduced charging efficiency. Therefore, a certain anti-falling design is required. The traditional anti-falling design is achieved by direct extrusion and friction between the charging gun and the charging mechanism charging connection end. This structure has poor anti-falling effect, and long-term plugging and unplugging can easily cause wear and tear, further reducing the anti-falling effect, making the charging gun prone to loosening. Another anti-falling mechanism is achieved by setting a buckle between the charging mechanism and the charging gun to prevent falling off. This structure also has wear and tear problems, and when subjected to violent plugging and unplugging, it may also break off. In addition, it is not convenient to observe and repair after wear and tear or breakage.

[0004] Therefore, the present application provides a new energy vehicle charging anti-falling mechanism to solve the above problems. SUMMARY

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present application provides a new energy vehicle charging anti-falling mechanism to solve the problem of poor anti-falling effect.

[0006] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0007] A new energy vehicle charging anti-detachment mechanism includes a fixed base, on which a charging mechanism is provided. The charging mechanism includes a charging slot opened on the front side of the fixed base and a plurality of charging connection ends disposed in the charging slot. The rear end of the charging connection end slides through the fixed base in the front-back direction and is provided with an elastic limiting mechanism. The charging mechanism also includes a slide plate that slides in the charging slot in the front-back direction and a baffle plate fixedly disposed on a portion of the charging connection ends. The baffle plate is located in front of the slide plate. The fixed base has a cavity communicating with the charging slot. A transmission mechanism is provided in the cavity. The transmission mechanism includes a gear that rotates in the cavity and a rack that slides in the cavity. The rack is meshed with the gear. The gear is fixedly connected to a rotating arm. The rotating arm is connected to a locking piece A. A pull rope is provided between the rack and the slide plate.

[0008] It also includes a card B that is compatible with card A. Card B is used to install on the charging gun. When the charging gun is inserted into the charging slot, it drives the slider to move to the last side, which in turn drives the pull rope, rack, gear, rotating arm and card A to move in sequence, so that card A corresponds to card B.

[0009] Preferably, the fixed base is provided with two charging mechanisms, namely a first charging mechanism and a second charging mechanism. The first charging mechanism includes a first charging slot, a first charging connection end, a first sliding plate and a first baffle. The second charging mechanism includes a second charging slot, a second charging connection end, a second sliding plate and a second baffle. A cavity is disposed between the two first charging slots and the second charging slot. A fixed plate is provided in the middle of the cavity. The gear is rotatably disposed on the fixed plate. The gear is fixedly connected to a connecting shaft and is fixedly connected to the rotating arm through the connecting shaft. The rack (806) is slidably disposed on the fixed plate in the left and right direction. Pull ropes are provided on the left and right sides of the rack and are connected to the corresponding sliding plates through the pull ropes. A dustproof plate A is provided on the rotating arm.

[0010] When the charging gun is inserted into one of the charging slots, so that card A corresponds to card B, the dustproof plate A seals off the other charging slot.

[0011] Preferably, the rack is U-shaped, and a return spring is provided between the two ends of the rack and the fixing plate.

[0012] Preferably, the cavity has an open front side and is provided with a dustproof plate B. The dustproof plate is detachably connected to the fixed base, the connecting shaft passes through the dustproof plate B and is detachably connected to the rotating arm, and the return spring is detachably connected to the fixed plate and the rack.

[0013] Preferably, the dustproof plate B is made of rubber, snaps into the cavity, and has metal through holes adapted to the connecting shaft.

[0014] Preferably, the elastic limiting mechanism is located on the rear side of the fixed base and includes a connecting plate, a connecting rod, and a limiting spring. The connecting plate is fixedly connected to the charging connection end, and the rear end of the charging connection end passes through the connecting plate. The limiting spring is located between the connecting rod and the fixed base.

[0015] Preferably, the card A is a protrusion with a universal ball at the end, and the card B is a tapered slot.

[0016] For optimal performance, the pull rope is replaced with a steel wire rope.

[0017] Preferably, the slider is in a sealed sliding connection with the charging slot and the charging connection end.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. In this invention, clip B is used to install on the charging gun. During charging, the charging gun is first inserted into the charging slot and connected to the charging connector. As the charging gun is further inserted, it drives the charging connector to move. The charging connector drives the baffle to move, the baffle drives the slider to move, the slider drives the rack to move through the pull rope, the rack drives the gear to rotate, and the gear drives the rotating arm to rotate until the rotating arm rotates to its maximum angle. Clip A on the rotating arm corresponds to clip B on the charging gun. Then, the charging gun is quickly moved backward so that clip A and clip B engage. Under the action of the elastic limiting mechanism, the charging connector and the charging gun are tightly pressed together, thereby preventing them from falling off.

[0020] 2. In this invention, when the charging gun is being charged, it is limited by clips B and A and the rotating arm, preventing it from moving forward when subjected to an outward force. Clips A and B are easy to observe, and even if wear or damage occurs, they are easy to detect and replace. When the charging gun is subjected to an inward force, if the force is small, clips A and B do not disengage, and the charging gun moves backward a short distance before resetting. If the force is large, clips A and B disengage, and the charging gun moves backward a distance before resetting. After resetting, clips A and B disengage, and the rotating arm rotates under gravity. By observing the state of the rotating arm, the state of clips A and B can be determined, allowing for re-locking and restoring the anti-disengagement state. Furthermore, when the charging gun is subjected to a backward force, the charging connection end moves backward, reducing the impact and friction between the charging gun and the charging connection end, thus protecting the charging connection end and the charging gun.

[0021] 3. In practical operation, the present invention only requires one hand to hold the charging gun, which can realize the plugging, unplugging and fixing of the charging gun, making it easy to operate. Attached Figure Description

[0031] The following will refer to the attached reference. Figures 1 to 8 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] A new energy vehicle charging anti-detachment mechanism, as shown in the attached figure. Figure 1 , Figure 2As shown, the device includes a fixed base 1, which is erected. A charging mechanism is provided on the fixed base 1. The charging mechanism includes a charging slot opened on the front side of the fixed base 1 and a plurality of charging connection ends disposed in the charging slot. The charging connection ends are arranged in the front-back direction. In this embodiment, the fixed base 1 is provided with two charging mechanisms, namely a first charging mechanism 2 and a second charging mechanism 5. The first charging mechanism 2 is for fast charging, and the second charging mechanism is for slow charging. The first charging mechanism 2 includes a first charging slot, a first charging connection end 202, a first slider 201, and a first baffle 203. The second charging mechanism 5 includes a second charging slot, a second charging connection end 502, a second slider 501, and a second baffle 503.

[0033] In practical use, the charging gun is inserted into the charging slot from the front and connected to the charging connector to start charging. In this embodiment, two charging mechanisms, fast and slow, can be used for fast and slow charging of new energy vehicles. This part is existing technology and will not be described in detail here.

[0034] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the rear ends of the first charging connection end 202 and the second charging connection end 502 slide along the front-back direction through the fixed base 1 and are provided with an elastic limiting mechanism. That is, the first charging connection end 202 and the second charging connection end 502 remain stationary in their natural state, and can move along the front-back direction when subjected to force, overcoming the elastic limiting mechanism. Furthermore, the rear ends of the first charging connection end 202 and the second charging connection end 502 can be connected to corresponding spring wires, thereby connecting to the battery in the vehicle body. The spring wires can adaptively extend and retract when sliding.

[0035] The charging mechanism also includes a sliding plate that slides within the charging slot in a front-to-back direction and a baffle plate fixedly mounted on a portion of the charging connection end. The baffle plate is located in front of the sliding plate. The fixed base 1 has a cavity communicating with the charging slot. A transmission mechanism is provided within the cavity. The transmission mechanism includes a gear 802 that rotates within the cavity and a rack 806 that slides within the cavity. The rack 806 meshes with the gear 802. A rotating arm 6 is fixedly connected to the gear 802. A locking piece A7 is connected to the rotating arm 6. A pull rope 805 is provided between the rack 806 and the sliding plate. In this embodiment, the cavity is located between the first charging slot and the second charging slot. A fixed plate 801 is provided in the middle of the cavity. The gear 802 is rotatably mounted on the fixed plate 801. The rotation axis of the gear 802 is along the front-back direction. The gear 802 is fixedly connected to the connecting shaft 803 and is fixedly connected to the rotating arm 6 through the connecting shaft 803. The rack 806 is slidably mounted on the fixed plate 801 in the left-right direction. Pull ropes 805 are provided on the left and right sides of the rack 806 respectively and are connected to the corresponding sliding plates through the pull ropes 805. A dustproof plate A4 is provided on the rotating arm 6.

[0036] Working principle: When the first slider 201 in the first charging mechanism 2 moves backward under force to its final position, the corresponding pull rope 805 drives the rack 806 to move to the left. The rack 806 drives the gear 802 to move clockwise, the gear 802 drives the connecting shaft 803 to rotate clockwise, and the connecting shaft 803 drives the rotating arm 6 to rotate clockwise, so that the card A7 aligns with the first charging mechanism 2. At the same time, the dustproof plate A4 seals the second charging slot of the second charging mechanism 5. For specific details, please refer to the attached diagram. Figure 8 Conversely, when the second slider 501 in the second charging mechanism 5 moves backward under force, the corresponding pull rope 805 drives the rack 806 to move to the right. The rack 806 drives the gear 802 to rotate counterclockwise, the gear 802 drives the connecting shaft 803 to rotate counterclockwise, and the connecting shaft 803 drives the rotating arm 6 to rotate counterclockwise, so that the card A7 corresponds to the second charging mechanism 5. At the same time, the dustproof plate A4 seals the first charging slot of the first charging mechanism 2. When neither the first slider 201 nor the second slider 501 is under force, the rotating arm 6, the card A7, and the dustproof plate A4 are in a balanced position due to gravity. In this embodiment, the balanced position can be referred to the attached diagram. Figure 1 , Figure 2 The rotating arm 6 rotates within a range of -90° to 90°. At this time, the dustproof plate A4 does not block the first charging slot and the second charging slot.

[0037] It also includes a card B10 that is compatible with card A7. Card B10 is used to install on the charging gun. When the charging gun is inserted into the charging slot and moves backward, it can drive the baffle to move backward, which in turn drives the slider to move backward, so that card A7 corresponds to card B10.

[0038] In practical use, when installing the mounting base 1, an installation slot is provided on the vehicle body. First, the rear ends of the first charging connection terminal 202 and the second charging connection terminal 502 are connected to the battery inside the vehicle body through spring wires, leaving room for movement for the first charging connection terminal 202 and the second charging connection terminal 502. Then, the mounting base 1 is fixed in the installation slot, and a corresponding cover is set, thus completing the installation of the mounting base 1. A clip B10 is set on the corresponding charging gun. Normally, the cover is closed. When charging is required, the cover is first opened to expose the first charging mechanism 2 and the second charging mechanism 5. The corresponding charging mechanism is selected, such as the first charging mechanism 2 for fast charging. The charging gun is then inserted into the first charging slot, so that the charging gun is connected to the first charging slot. Once the charging connector 202 is connected, the charging gun is pushed further. The charging gun drives the first charging connector 202 to move backward over the elastic limiting mechanism until the first baffle 203 contacts the first slider 201, causing the first slider 201 to move together. As the first slider 201 moves, it drives the transmission mechanism until it reaches the bottom. At this point, the rotating arm 6 drives the locking piece A7 to move to the position corresponding to the locking piece B10, and then quickly reverses to drive the charging gun to move, so that the locking piece A7 engages with the locking piece B10, thus completing the fixing of the charging gun. At the same time, the rotating arm 6 drives the dustproof plate A4 to seal the second charging slot. Conversely, the movement principle is the same when slow charging is selected and the second charging mechanism 5 is used, which will not be elaborated on here.

[0039] In this embodiment, after the charging gun is fixed, the front side of the charging gun is blocked by the clips B10 and A7 and the rotating arm 6, preventing it from moving forward. The rear side is secured by the charging connection end and the elastic limiting mechanism. That is, the charging gun is fixed by the front and rear compression, thus preventing it from falling off. In this embodiment, clips A7 and B10 are exposed for easy observation. Even if wear and damage occur, it is easy to find and replace them. When the charging gun is subjected to an inward force, if the force is small, clips A7 and B10 do not disengage, and the charging gun moves backward a short distance before returning to its original position. If the force is large, clips A7 and B10 disengage. After the charging gun moves backward a certain distance and then resets, the locking pieces A7 and B10 disengage, and the rotating arm 6 rotates under gravity. At this time, the charging gun can maintain its charging state, but it can no longer prevent external forces from causing it to fall off. However, by observing the state of the rotating arm 6, the state of the locking pieces A7 and B10 can be determined, and the operation can be repeated to lock the locking pieces A7 and B10, restoring the anti-fall-off state. Furthermore, when the charging gun is subjected to a backward force, the charging connection end moves backward, which can reduce the impact and friction between the charging gun and the charging connection end, thereby protecting the charging connection end and the charging gun.

[0040] In this embodiment, during operation, the charging gun can be plugged in, unplugged, and fixed with just one hand, making the operation convenient.

[0041] In this embodiment, under natural conditions, the rotating arm 6 is in a balanced position, and neither of the two charging mechanisms is obstructed. When the cover on the vehicle body is opened, the desired charging mechanism can be quickly selected for operation. Furthermore, when one charging mechanism is used, the other charging mechanism can be simultaneously blocked by the dustproof plate A4, thus protecting both charging mechanisms when the cover is open. Moreover, the two charging mechanisms share a single card A7 and dustproof plate A4, making the overall structure relatively simple.

[0042] In this embodiment, by blocking one charging mechanism while using another, the other charging mechanism cannot be used, thus avoiding the situation of using two charging mechanisms at the same time. This completely avoids the erroneous operation of simultaneously fast charging and slow charging the vehicle body, preventing the battery management system from becoming chaotic, unable to accurately judge and control the charging status, thereby affecting the safety and lifespan of the battery, causing different charging currents and voltages to interfere with each other, causing circuit failures, and even posing a serious risk of fire, thus protecting the vehicle body.

[0043] As attached Figure 1 , Figure 2 , Figure 3 As shown, in this embodiment, the rack 806 is U-shaped, and the left and right ends can serve as a connection. A return spring 804 is provided between the two ends of the rack 806 and the fixing plate 801. Since the position of the fixing plate 801 is fixed, the rack 806 can be automatically reset to the balance position by the return spring 804 when no external force is applied. In actual use, there is no need to rely on gravity, so that when the fixing base 1 is placed flat, all structures can also be reset, making the use and installation more flexible.

[0044] As attached Figure 1 , Figure 2 , Figure 6 As shown, in this embodiment, the front of the cavity is open and a dustproof plate B3 is provided. The dustproof plate B3 can protect the cavity from dust, and the dustproof plate B3 is detachably connected to the fixed base 1. Specifically, the dustproof plate B3 is made of rubber and snaps into the cavity. It has a metal through hole that matches the connecting shaft 803. The connecting shaft 803 passes through the dustproof plate B3 and is detachably connected to the rotating arm 6. The return spring 804 is detachably connected to the fixed plate 801 and the rack 806. The transmission mechanism of the cavity can be inspected and replaced by removing the rotating arm 6, installing or removing the dustproof plate B3.

[0045] As attached Figure 1 , Figure 5As shown, in this embodiment, the elastic limiting mechanism is located on the rear side of the fixed base 1, including a connecting plate 903, a connecting rod 902, and a limiting spring 901. The connecting plate 903 is fixedly connected to the charging connection end, and the rear end of the charging connection end passes through the connecting plate 903. The limiting spring 901 is located between the connecting rod 902 and the fixed base 1, which can elastically limit the charging connection end. Furthermore, by connecting each charging connection end through the connecting plate 903, each charging connection end can move synchronously, thereby ensuring stable communication with the charging gun.

[0046] As attached Figure 1 , Figure 6 As shown, in this embodiment, the card A7 is a protrusion with a universal ball at its end, and the card B10 is a tapered slot. When the charging gun is inserted into the charging slot and quickly reversed to move the charging gun, even if the rotating arm 6 rotates slightly, causing the card A7 and card B10 to not be completely aligned, the card A7 can still be controlled to move to align with the card B10 after the card A7 and card B10 come into contact, and the card A7 and card B10 can be locked together. Furthermore, the universal ball reduces friction and wear, reduces operational requirements, and makes it more convenient to use.

[0047] In addition, in this embodiment, the pull rope 805 is made of steel wire rope. Steel wire rope has high strength, light weight, low working noise, and long service life. The slider is sealed and slidably connected to the charging slot and the charging connection end. That is, the space behind the slider is relatively sealed, which can prevent dust in this part of the space, thus making it easy to clean the entire charging slot.

[0048] It should be noted that in the description of this invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0049] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
