Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to a charging anti-falling mechanism for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. At present, most new energy vehicles on the market use electricity, that is, new energy electric vehicles, which are equipped with a charging mechanism that can be charged through a charging gun to provide electrical energy for the electric vehicle's drive motor, and convert the electrical energy of the power supply into mechanical energy through the motor.

[0003] During the actual charging process of new energy vehicles, it is necessary to ensure the stable connection between the charging gun and the charging mechanism during charging to avoid being affected by external forces and falling off, resulting in charging interruption or reduced charging efficiency. That is, a certain anti-falling design is required. The traditional anti-falling design is directly achieved through the extrusion and friction between the charging gun and the charging connection end of the charging mechanism. The anti-falling effect of this structure is not good, and long-term plugging and unplugging can easily cause wear, further reducing the anti-falling effect and making the charging gun easy to loosen. There is also an anti-falling mechanism that achieves anti-falling by setting a buckle between the charging mechanism and the charging gun. This structure also has the problem of wear, and when it is violently plugged and unplugged, it will also be disconnected and broken, and it is inconvenient to observe and repair after wear or disconnection.

[0004] Therefore, the present invention provides a new energy vehicle charging anti-falling mechanism to solve the above-mentioned problem. Summary of the invention

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

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

[0013] Preferably, the dustproof plate B is made of rubber material, is snap-fitted to the cavity, and is provided with a metal through-hole adapted to the connecting shaft.

[0014] Preferably, the elastic limiting mechanism is arranged on the rear side of the fixing seat, including 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, and the limiting spring is arranged between the connecting rod and the fixing seat.

[0019] 1. The card B in the present invention is used to be installed on the charging gun. When charging, first, the charging gun is inserted into the charging slot and connected with the charging connection end. Then, as the charging gun continues to be inserted, the charging connection end is driven to move, the charging connection end drives the baffle to move, the baffle drives the slide to move, the slide 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 the maximum angle. The card A on the rotating arm corresponds to the position of the card B on the charging gun. Then, the charging gun is quickly moved backward to engage the card A with the card B, and under the action of the elastic limiting mechanism, the charging connection end and the charging gun are tightly squeezed together, thereby playing a role in preventing them from falling off.

[0020] 2. In the present invention, when charging is performed through the charging gun, when the charging gun is subjected to outward force, it is limited by the clamp B, clamp A and the rotating arm and cannot move forward. The clamp A and clamp B are easy to observe, and even if they are worn and damaged, they are easy to find and replace. When the charging gun is subjected to inward force, when the force is small, the clamp A and clamp B are not disengaged, and the charging gun first moves backward for a short distance and then resets. When the force is large, the clamp A and clamp B are disengaged, and the charging gun moves backward for a distance and then resets. After resetting, the clamp A and clamp B are disengaged, and the rotating arm rotates under the action of gravity. The state of the clamp A and clamp B can be known by observing the state of the rotating arm, so that it can be operated again to re-secure it and restore the anti-falling state. When the charging gun is subjected to 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.

[0021] 3. In the specific operation of the present invention, only one hand is needed to hold the charging gun for operation, and the charging gun can be plugged in, unplugged and fixed, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0032] A new energy vehicle charging anti-falling mechanism, as shown in the attached Figure 1 , Figure 2As shown, it includes a fixed base 1, which is upright. 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 terminals arranged in the charging slot. The charging connection terminals are along the front-to-back direction. In this embodiment, two left and right charging mechanisms are provided on the fixed base 1, namely a first charging mechanism 2 and a second charging mechanism 5, wherein the first charging mechanism 2 is fast charging and the second charging mechanism is slow charging. The first charging mechanism 2 includes a first charging slot, a first charging connection terminal 202, a first slide 201 and a first baffle 203. The second charging mechanism 5 includes a second charging slot, a second charging connection terminal 502, a second slide 501 and a second baffle 503.

[0033] During specific use, insert the charging gun into the charging slot from the front side, and connect it to the charging connection end to achieve charging. In this embodiment, two charging mechanisms, fast charging and slow charging, are used for fast charging and slow charging of new energy vehicles. This part is existing technology and will not be elaborated on 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 are slidably inserted into the fixing seat 1 along the front-to-back direction 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 a natural state, and can move forward and backward by overcoming the elastic limiting mechanism when subjected to force, and the rear ends of the first charging connection end 202 and the second charging connection end 502 can be connected to corresponding spring wires, and then connected to the battery in the vehicle body, and the spring wires can be adaptively retracted and contracted during sliding.

[0035] The charging mechanism also includes a slide plate slidably arranged in the charging slot along the front-back direction and a baffle fixedly arranged on a part of the charging connection end, the baffle is located in front of the slide plate, a cavity connected to the charging slot is opened on the fixing seat 1, a transmission mechanism is arranged in the cavity, the transmission mechanism includes a gear 802 rotatably arranged in the cavity and a rack 806 slidably arranged in the cavity, the rack 806 is meshed and connected with the gear 802, the gear 802 is fixedly connected with a rotating arm 6, the rotating arm 6 is connected with a clamp A7, and a pull rope 805 is arranged between the rack 806 and the slide plate In this embodiment, the cavity is arranged between the first charging slot and the second charging slot, and a fixed plate 801 is provided in the middle of the cavity. The gear 802 is rotatably arranged on the fixed plate 801. The rotating axis of the gear 802 is along the front-to-back direction. The gear 802 is fixedly connected with a connecting shaft 803, and is fixedly connected to the rotating arm 6 through the connecting shaft 803. The rack 806 is slidably arranged on the fixed plate 801 along the left-right direction. Pull ropes 805 are respectively provided on the left and right sides of the rack 806, and are connected to the corresponding sliding sheet through the pull ropes 805. A dustproof plate A4 is provided on the rotating arm 6.

[0036] Working principle: When the first slide 201 in the first charging mechanism 2 is forced to move backward to the end, the corresponding pull rope 805 drives the rack 806 to move leftward, the rack 806 drives the gear 802 to move clockwise, the gear 802 drives the connecting shaft 803 to rotate clockwise, the connecting shaft 803 drives the rotating arm 6 to rotate clockwise, so that the card A7 corresponds to the first charging mechanism 2, and the dustproof plate A4 blocks the second charging slot of the second charging mechanism 5. For specific status, please refer to the attached Figure 8 On the contrary, when the second slide 501 in the second charging mechanism 5 is forced to move backward to the last position, the corresponding pull rope 805 drives the rack 806 to move rightward, 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, and the dustproof plate A4 blocks the first charging slot of the first charging mechanism 2; when the first slide 201 and the second slide 501 are not subjected to force, the rotating arm 6, the card A7, and the dustproof plate A4 are in a balanced position due to gravity. The balanced position in this embodiment can be referred to in the attached figure. Figure 1 , Figure 2 The rotation range of the rotating arm 6 is -90 to 90 degrees. 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 the card A7. The card B10 is used to be installed 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, and then drive the slide to move backward, so that the card A7 corresponds to the card B10.

[0038] In specific use, when installing the fixing seat 1, a mounting groove 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 in the vehicle body through a spring wire, and movement space is reserved for the first charging connection terminal 202 and the second charging connection terminal 502. Then, the fixing seat 1 is fixed in the mounting groove, and a corresponding cover is set, that is, the installation of the fixing seat 1 is completed, and a card B10 is set on the corresponding charging gun; the cover is usually closed. When charging is required, the cover is first opened to expose the first charging mechanism 2 and the second charging mechanism 5, and the corresponding charging mechanism is selected. For example, for fast charging, the first charging mechanism 2 is selected, and the charging gun is inserted into the first charging slot so that the charging gun is connected to the first The charging connection terminal 202 is adapted to be connected, and then the charging gun is continued to be pushed, and the first charging connection terminal 202 is driven by the charging gun to overcome the elastic limiting mechanism and move backward until the first blocking piece 203 contacts the first sliding piece 201, driving the first sliding piece 201 to move together, and with the movement of the first sliding piece 201, the transmission mechanism is driven until it moves to the bottom. At this time, the rotating arm 6 drives the card A7 to move to the position corresponding to the card B10, and then quickly drives the charging gun to move in the opposite direction, so that the card A7 is engaged with the card B10, and the charging gun is fixed. At the same time, the rotating arm 6 drives the dustproof plate A4 to block the second charging slot. On the contrary, when slow charging is selected and the second charging mechanism 5 is used, the movement principle is the same, and no further details will be given here.

[0039] In this embodiment, after the charging gun is fixed, the front side of the charging gun is blocked by the clamp B10, the clamp A7 and the rotating arm 6 and cannot move forward. The rear side is fixed by the charging connection end and the elastic limiting mechanism, that is, the charging gun is fixed by squeezing the front and rear sides, thereby preventing it from falling off. In this embodiment, the clamp A7 and the clamp B10 are exposed to facilitate observation. Even if they are worn and damaged, they are easy to find and replace. When the charging gun is subjected to an inward force, when the force is small, the clamp A7 and the clamp B10 are not disengaged, and the charging gun first moves backward a short distance and then resets. When the force is large, the clamp A7 and the clamp B10 are disengaged. The charging gun moves backward for a distance and then resets. After resetting, the clamp A7 and the clamp B10 are disengaged, and the rotating arm 6 rotates under the action of gravity. At this time, the charging gun can maintain the charging state, but it can no longer prevent the outward force from falling off. However, the state of the rotating arm 6 can be observed to know the state of the clamp A7 and the clamp B10, so as to operate again to fix the clamp A7 and the clamp B10 and restore the anti-falling state. When the charging gun is subjected to 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 the specific operation, only one hand is needed to hold the charging gun for operation, so that the charging gun can be plugged in, unplugged and fixed, which is convenient to operate.

[0041] In this embodiment, in a natural state, the rotating arm 6 is in a balanced position, and the two charging mechanisms are not blocked. When the cover on the vehicle body is opened, the required charging mechanism can be quickly selected for operation, and when one charging mechanism is used, the other charging mechanism can be blocked at the same time by the dustproof plate A4, so that both charging mechanisms can be protected when the cover is opened, and the two charging mechanisms share a card A7 and a dustproof plate A4, and the overall structure is relatively simple.

[0042] In the present embodiment, since one charging mechanism is blocked when the other charging mechanism is in use, making the other charging mechanism unusable, the situation of using two charging mechanisms at the same time can be avoided, thereby completely avoiding the erroneous operation of fast charging and slow charging of the vehicle body at the same time, and avoiding confusion in the battery management system, the inability to accurately judge and control the charging status, thereby affecting the safety and life of the battery, causing different charging currents and voltages to interfere with each other, causing circuit failures, and even serious problems such as the risk of fire, thereby protecting the vehicle body.

[0043] As attached Figure 1 , Figure 2 , Figure 3 As shown, in this embodiment, the rack 806 is in a "U" shape, and the left and right ends can play a connecting role, so that a reset spring 804 is provided between the two ends of the rack 806 and the fixed plate 801. Since the position of the fixed plate 801 is fixed, when there is no external force, the rack 806 can be automatically reset to a balanced position through the reset spring 804. In specific use, there is no need to rely on gravity, so that when the fixed base 1 is placed flat, each structure can also be reset, and the use and installation are more flexible.

[0044] As attached Figure 1 , Figure 2 , Figure 6 As shown, in this embodiment, the front side of the cavity is open and is provided with a dustproof plate B3. The cavity can be protected from dust by the dustproof plate B3, and the dustproof plate B3 is detachably connected to the fixing seat 1. Specifically, the dustproof plate B3 is made of rubber material, is clamped with the cavity, and is provided with a metal perforation adapted to the connecting shaft 803. The connecting shaft 803 passes through the dustproof plate B3 and is detachably connected to the rotating arm 6. The reset spring 804 is detachably connected to the fixing plate 801 and the rack 806. The dustproof plate B3 can be installed and removed by disassembling the rotating arm 6, and the transmission mechanism of the cavity can be inspected and replaced.

[0045] As attached Figure 1 , Figure 5As shown, in this embodiment, the elastic limiting mechanism is arranged on the rear side of the fixed seat 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 arranged between the connecting rod 902 and the fixed seat 1, which can realize elastic limiting of the charging connection end, and the charging connection ends are connected through the connecting plate 903, which can make the charging connection ends move synchronously, thereby ensuring stable connection with the charging end.

[0046] As attached Figure 1 , Figure 6 As shown, in this embodiment, the card A7 is a protrusion and a universal ball is provided at the end. The card B10 is a conical card slot. When the charging gun is inserted into the charging slot and the charging gun is quickly driven to move in the reverse direction, even if the rotating arm 6 rotates slightly, so that the card A7 and the card B10 are not completely corresponding, after the card A7 and the card B10 contact, the card A7 can be controlled to move to correspond to the card B10, and the card A7 and the card B10 are fixed, and the friction between them is reduced by the universal ball, the wear is reduced, and the requirements for operation are reduced, so that it is more convenient to use.

[0047] In addition, in the present embodiment, the pull rope 805 is replaced by a steel wire rope, which has high strength, light weight, low working noise and long service life. The slide is sealed and slidably connected to the charging slot and the charging connection end, that is, the space behind the slide is relatively closed, which can prevent dust from entering this part of the space, thereby facilitating the cleaning of the entire charging slot.

[0048] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0049] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle 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 these changes or substitutions will fall within the protection scope of the present invention.
