Description

Technical Field

[0001] The present invention relates to the technical field of protective devices, and more particularly, to a protective device for a charging pile control panel. Background Art

[0002] Charging piles are devices that replenish electricity for electric vehicles. Their function is similar to that of gas pumps in traditional gas stations. Floor-standing models are mostly installed in outdoor parking lots or community parking spaces. Users operate them through the control panel on the front of the charging pile, which accounts for a relatively high cost of the entire machine.

[0003] However, in actual scenarios, the following situations often occur: the driver makes an operational error when reversing, or mistakenly presses the brake pedal instead of the accelerator pedal, causing the vehicle to collide with the charging pile. In addition, different types of vehicles such as SUVs, trucks, and sedans have different body heights. When these vehicles collide with the front of the charging pile, the vibration or deformation of the charging pile itself can easily cause damage to the control panel. What's worse, the vehicle directly collides with the control panel, making the control panel the first to bear the brunt of the damage, so damage often occurs. Summary of the Invention

[0004] The present invention provides a protective device for a charging pile control panel, which solves the technical problem in the related art that the control panel is easily damaged.

[0005] The present invention provides a protective device for a charging pile control panel, comprising a charging pile and a control panel arranged on the charging pile, wherein the charging pile is provided with a plurality of protective mechanisms for protecting the control panel;

[0006] A buffer guide mechanism is provided at the bottom of the charging pile, and a positioning mechanism and a reminder mechanism are provided on the buffer guide mechanism. The positioning mechanism is used to prevent the charging pile from moving back after it moves;

[0007] The charging pile has a first position state, a second position state and a third position state;

[0008] In the first position state, the protection mechanism is cushioned by vehicle collision;

[0009] In the second position state, the vehicle acts on the charging pile to move along the buffer guide mechanism, and the positioning mechanism and the buffer guide mechanism alternately change the connection state. During the alternating connection state, the vehicle acts on the reminder mechanism to sound a reminder.

[0010] In the third position state, the charging pile is separated from the buffer guide mechanism by the action of the vehicle and provides buffering when it falls.

[0011] As a further optimization solution of the present invention, the protection mechanism includes a mounting rod and an anti-collision tube, and the anti-collision tube is connected to the charging pile through the mounting rod to cushion the impact.

[0012] As a further optimization solution of the present invention, the anti-collision tube has a flexible part and a rigid part, and the rigid part is connected to the charging pile through a mounting rod.

[0013] As a further optimization scheme of the present invention, the interior of the anti-collision tube is filled with liquid, and a plug is provided at the top of the anti-collision tube, a hanging rope is connected between the two plugs, a hanging ring is provided on the hanging rope, and the hanging ring is connected to protective plate one, and protective plate one is hinged to the control panel through protective plate two.

[0014] As a further optimization scheme of the present invention, the buffer guide mechanism includes a guide frame, a right-angle plate, a guide block and a buffer spring. The guide frame forms an opening upward, and the guide block is slidably arranged inside the guide frame. One end of the buffer spring is fixedly connected to the guide block, and the other end is connected to one end inside the guide frame. The right-angle plate is located at the top of the guide frame and is fixedly connected to the guide block, and the right-angle plate is fixedly connected to the bottom of the charging pile.

[0015] As a further optimization solution of the present invention, a guide rod is horizontally installed inside the guide frame, and the guide rod slides through the buffer spring.

[0016] As a further optimization scheme of the present invention, the positioning mechanism includes a positioning pin and a return spring. The insertion end of the positioning pin is tilted and slides into the interior of the guide frame. One side of the guide frame is provided with multiple slots along its length direction that are adapted to the insertion end of the positioning pin. The return spring is movably sleeved on the outer periphery of the positioning pin. One end of the return spring is connected to the reminder mechanism, and the other end is connected to the T-shaped end of the positioning pin.

[0017] As a further optimization scheme of the present invention, the reminder mechanism includes a sleeve, a moving block and a sounding member. The sleeve is installed on a right-angle plate, the moving block is slidably arranged inside the sleeve, the insertion end of the positioning pin slides through the sleeve and the moving block, and the sounding member is arranged on the sleeve.

In case of further collisions, the charging pile slides directionally along the buffer guide mechanism, the buffer spring and the guide rod ensure smooth buffering, and the positioning pin and the slot cooperate to prevent back movement. In case of severe collisions, the buffer bag absorbs the impact force during the dumping process. This system can cope with collisions of different models such as SUVs, trucks, and cars, adapt to complex outdoor environments, greatly reduce the probability of damage to the control panel, and extend its service life.

[0022] 2. The protective device for the charging pile control panel described in the present invention automatically blocks the control panel through a protective plate upon collision, and the reminder mechanism warns surrounding personnel in real time through a sounding member. The positioning mechanism prevents the charging pile from moving back and causing secondary damage, thereby protecting both equipment and personnel safety and reducing the risk of accidents expanding. At the same time, the rigid-flexible design of the anti-collision tube, the directional sliding structure of the buffer guide mechanism, and the coordination of the positioning pin and the return spring ensure the stability of the overall structure and high buffering efficiency, thereby improving the reliability of the device.

[0038] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0039] like Figure 1 As shown, a protective device for a charging pile control panel according to an embodiment of the present invention includes a charging pile 1 and a control panel 2 arranged on the charging pile 1. A buffer bag 7 is provided on the top of the back of the charging pile 1. The buffer bag 7 is an air bag. The charging pile 1 is provided with several groups of protective mechanisms 3 for protecting the control panel 2.

[0040] A buffer guide mechanism 4 is provided at the bottom of the charging pile 1. A positioning mechanism 5 and a reminder mechanism 6 are provided on the buffer guide mechanism 4. The positioning mechanism 5 is used to prevent the charging pile 1 from moving back after it moves.

[0041] The charging pile 1 has a first position state, a second position state and a third position state;

[0042] In the first position state, the protection mechanism 3 is buffered by the collision of the vehicle;

[0043] In the second position state, the vehicle acts on the charging pile 1 to move along the buffer guide mechanism 4, and the positioning mechanism 5 and the buffer guide mechanism 4 alternately change the connection state. During the connection state alternation, the vehicle acts on the reminder mechanism 6 to sound a reminder.

[0044] In the third position, the charging pile 1 is separated from the buffer guide mechanism 4 by the action of the vehicle and provides buffering when it falls.

[0045] The protective mechanism 3 on the charging pile 1 provides the first layer of protection for the control panel 2. The buffer guide mechanism 4 at the bottom is used to guide the movement direction of the charging pile 1 after it is subjected to force and to provide buffering. The positioning mechanism 5 can limit the back movement of the charging pile 1 after it moves. The reminder mechanism 6 issues a reminder when the positioning and buffer mechanism states alternate.

[0046] When in the first position: the vehicle first contacts the protection mechanism 3 , and the protection mechanism 3 absorbs the impact energy through its own structural deformation, thereby reducing the impact force transmitted to the control panel 2 and preliminarily protecting the panel 2 .

[0047] When in the second position: the impact force causes the charging pile 1 to move in a directional manner along the buffer guide mechanism 4. During the movement, the connection status of the positioning mechanism 5 and the buffer guide mechanism 4, such as the positioning pin 51 inserted into or out of the slot 411, changes alternately. This alternating action triggers the reminder mechanism 6 to sound, which can further buffer the force through the buffer guide mechanism 4 and prevent the charging pile 1 from moving back through positioning, while issuing a reminder alert to the surroundings.

[0048] Due to continuous collisions, when in the third position state: the charging pile 1 is forced to separate from the buffer guide mechanism 4, and is cushioned by the buffer bag 7 during the tipping process, thereby reducing the vibration after the charging pile 1 falls to the ground and causing damage to the control panel 2. Through the progressive protection of the three-level position state, from initial buffering to directional movement buffering to tipping buffering, combined with the reminder function, the risk of damage to the control panel 2 is reduced in all directions.

[0049] like Figure 2 、 Figure 3 and Figure 7 As shown, the protection mechanism 3 includes a mounting rod 31 and an anti-collision tube 32 . The anti-collision tube 32 is connected to the charging pile 1 through the mounting rod 31 to cushion the impact.

[0050] When a vehicle collides, the anti-collision tube 32 contacts the vehicle before the control panel 2, and absorbs the impact energy through deformation of its own material (such as bending and compression). The mounting rod 31 stably connects the anti-collision tube 32 to the charging pile 1, ensuring that the anti-collision tube 32 can effectively bear the impact force, avoiding the anti-collision tube 32 from falling off and causing protection failure. The deformation buffer of the anti-collision tube 32 and the stable connection of the mounting rod 31 are used to form a physical barrier, reducing the probability of the vehicle directly colliding with the control panel 2 and enhancing the initial protection capability.

[0051] Furthermore, the anti-collision tube 32 has a flexible portion and a rigid portion, and the rigid portion is connected to the charging pile 1 through the mounting rod 31 .

[0052] Flexible part: Thermoplastic polyurethane elastomer (TPU) can be selected. It has excellent wear resistance, high elasticity and high mechanical strength. It can fully deform and absorb energy during a collision. Rubber materials such as natural rubber or synthetic rubber can also be selected. They have good flexibility and low cost. They can effectively buffer minor collisions and are commonly used in protective devices such as flexible anti-collision guardrails.

[0053] Rigid part: Carbon fiber material is used, which has high strength, light weight, good fatigue resistance, can firmly support the protective structure, and can ensure the overall protective performance. Ultra-high molecular weight polyethylene can also be used. It has super wear resistance, self-lubrication, high strength and stable chemical properties, which can ensure that the rigid part can work stably for a long time in complex environments.

[0054] When a vehicle collides, the flexible part first deforms, such as bending and squeezing, and absorbs most of the impact energy through its own elastic deformation. The rigid part, due to its fixed connection with the mounting rod 31, maintains the overall structural stability of the anti-collision tube 32, avoiding excessive deformation of the flexible part that may cause the anti-collision tube 32 to separate from the charging pile 1, ensuring continuous and effective protection. The flexible part is responsible for buffering and energy absorption, and the rigid part is responsible for structural stability. The combination of the two enables the anti-collision tube 32 to adapt to collisions of different intensities and maintain a stable protection position, thereby improving the reliability of the protection mechanism 3.

[0055] like Figures 1 to 3 As shown, the interior of the anti-collision tube 32 is filled with liquid, and a plug 33 is provided at the top of the anti-collision tube 32, a hanging rope 34 is connected between the two plugs 33, a hanging ring 35 is provided on the hanging rope 34, and the hanging ring 35 is connected to a protective plate 1 36, and the protective plate 1 36 is hinged to the control panel 2 through a protective plate 2 37.

[0056] When the vehicle collides with the anti-collision tube 32, the flexible part of the anti-collision tube 32 deforms and squeezes the internal liquid. The impact energy is further consumed during the flow of the liquid, which is similar to a hydraulic buffer. Since the flexible part is squeezed, the internal liquid acts on the plug 33, causing the plug 33 to separate from the anti-collision tube 32, releasing the impact energy. The separation of the plug 33 from the anti-collision tube 32 releases the restriction of the hanging rope 34 on the hanging ring 35, and the protective plate 1 36 and the protective plate 2 37 rotate accordingly, and finally the protective plate 1 36 covers the surface of the control panel 2 to form a physical shielding. The liquid flow enhances the buffering energy absorption effect. The linkage between the protective plate 1 36 and the protective plate 2 37 realizes active shielding of the control panel 2. The double protection reduces the risk of the panel being directly hit. At the same time, when the protective plate 1 36 and the protective plate 2 37 are not protected, they play an auxiliary role in shielding the top of the control panel 2, which is convenient for the operator to use.

[0057] like Figure 4As shown, the buffer guide mechanism 4 includes a guide frame 41, a right-angle plate 42, a guide block 43 and a buffer spring 44. The guide frame 41 forms an opening upward, and the guide block 43 is slidably arranged inside the guide frame 41. One end of the buffer spring 44 is fixedly connected to the guide block 43, and the other end is connected to one end inside the guide frame 41. The right-angle plate 42 is located at the top of the guide frame 41 and is fixedly connected to the guide block 43, and the right-angle plate 42 is fixedly connected to the bottom of the charging pile 1.

[0058] When the anti-collision tube 32 is hit and drives the charging pile 1 to continue moving, the impact force is transmitted to the guide block 43 through the right-angle plate 42, causing the guide block 43 to slide along the length direction of the guide frame 41 and compress the buffer spring 44 at the same time. The deformation of the buffer spring 44 generates a reverse elastic force, which offsets part of the impact force and realizes buffer energy storage. The guide frame 41 limits the sliding direction of the guide block 43 to ensure that the charging pile 1 moves along the preset trajectory and avoids secondary collisions caused by offset. The impact force is converted into a horizontal buffer force through the sliding of the guide block 43 and the deformation of the buffer spring 44, thereby reducing the instantaneous force on the charging pile 1 and the control panel 2.

[0059] Furthermore, a guide rod 45 is horizontally installed inside the guide frame 41, and the guide rod 45 slides through the buffer spring 44. A rolling member (not shown in the figure) is provided on the top of the guide frame 41, and the rolling member is rollingly connected to the right-angle plate 42. The rolling member is a ball, and the ball is rotatably sleeved on the guide frame 41 to facilitate smoother movement of the right-angle plate 42.

[0060] When the guide block 43 slides in the guide frame 41, the guide rod 45 provides guidance for the guide block 43 to prevent the guide block 43 from shifting or getting stuck during the sliding process. At the same time, the guide rod 45 limits the deformation direction of the buffer spring 44 to avoid lateral bending of the spring due to uneven force, ensuring that the buffering force of the spring is stable and effective, enhancing the structural stability of the buffer guide mechanism 4, and ensuring smooth sliding of the guide block 43 and regular deformation of the buffer spring 44.

[0061] like Figure 5 As shown, the positioning mechanism 5 includes a positioning pin 51 and a return spring 52. The insertion end of the positioning pin 51 is tilted and slides into the interior of the guide frame 41. One side of the guide frame 41 is provided with a plurality of slots 411 adapted to the insertion end of the positioning pin 51 along its length direction. The return spring 52 is movably sleeved on the outer periphery of the positioning pin 51. One end of the return spring 52 is connected to the reminder mechanism 6, and the other end is connected to the T-shaped end of the positioning pin 51.

[0062] When the charging pile 1 drives the guide block 43 to move, the guide block 43 squeezes the inclined insertion end of the positioning pin 51, causing the positioning pin 51 to exit the current slot 411. At this time, the return spring 52 is stretched to store energy. When the guide block 43 moves to the next slot 411, the return spring 52 resets, pushing the positioning pin 51 into the new slot 411, limiting the guide block 43 from moving back. Through the cooperation between the positioning pin 51 and the slot 411, the one-way positioning of the charging pile 1 after movement is realized to prevent back movement. The return spring 52 ensures that the positioning pin 51 can be automatically reset and inserted, thereby improving positioning reliability.

[0063] like Figure 5 and Figure 6 As shown, the reminder mechanism 6 includes a sleeve 61, a moving block 62 and a ringing member 63. The sleeve 61 is installed on the right-angle plate 42, the moving block 62 is slidably set inside the sleeve 61, the insertion end of the positioning pin 51 slides through the sleeve 61 and the moving block 62, and the ringing member 63 is set on the sleeve 61.

[0064] When the positioning pin 51 is squeezed out of the slot 411 by the guide block 43, the inserted end of the positioning pin 51 slides on the side of the guide frame 41. At the same time, the positioning pin 51 drives the moving block 62 to slide in the sleeve 61. As the positioning pin 51 reciprocates in and out of the slot 411, the moving block 62 reciprocates to squeeze the air inside the sleeve 61. The air inside the sleeve 61 passes through the sounding piece 63 to make it sound, forming a continuous sound. The action linkage of the positioning mechanism 5 is used to trigger the sound, which promptly reminds the surrounding personnel of the collision, facilitating rapid response and processing.

[0065] Specifically, the sounding member 63 is an air nozzle or a whistle. When the air nozzle is selected, the air nozzle is set at the exhaust port of the sleeve 61. When the whistle is selected, the air inlet of the whistle is connected to the exhaust port of the sleeve 61.

[0066] Working principle:

[0067] When in the first position, when a vehicle collides, the protective mechanism 3 first contacts the collision force, and the anti-collision tube 32 is fixed to the charging pile 1 through the mounting rod 31. The flexible part deforms first to absorb energy, while the rigid part maintains structural stability. The internal liquid flows with the deformation of the anti-collision tube 32 to further cushion the impact force. At the same time, the anti-collision tube 32 is squeezed by the impact liquid and the plug 33 is separated from the anti-collision tube 32. The hanging rope 34 releases the limit of the hanging ring 35, and the protective plate 1 36 and the protective plate 2 37 rotate to cover the control panel 2, forming a physical shielding to reduce the risk of direct collision.

[0068] In the second position, if the impact force is large, the charging pile 1 drives the guide block 43 to slide along the guide rod 45 in the guide frame 41 through the right-angle plate 42, compressing the buffer spring 44, converting the impact force into the elastic potential energy of the spring to achieve directional buffering. The rolling element on the top of the guide frame 41 reduces the friction of the movement of the right-angle plate 42 to ensure smooth sliding.

[0069] During the movement, the guide block 43 squeezes the inclined end of the positioning pin 51 to make it exit the slot 411, and the return spring 52 stretches to store energy. When the guide block 43 moves to the next slot 411, the return spring 52 pushes the positioning pin 51 to insert, limiting the back movement of the charging pile 1. The reciprocating action of the positioning pin 51 drives the moving block 62 to slide in the sleeve 61, squeezing the air to make the sounding piece 63 sound, alerting people around.

[0070] In the third position, the charging pile 1 continues to move, and the charging pile 1 breaks away from the buffer guide mechanism 4 and falls over. At this time, the buffer bag 7 on the top of the back first contacts the ground, and absorbs the impact force of the fall through its own deformation (such as gas compression and elastic material deformation), thereby reducing the damage to the control panel 2 caused by the vibration of the whole machine.

[0071] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
