Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a semi-buried charging pile. Background Art

[0002] In order to reduce the damage caused by vehicle collisions with charging piles, the charging pile industry has adopted two major types of anti-collision technologies: passive and active. Passive anti-collision technology mainly improves collision resistance through structural reinforcement and external buffering. On the other hand, active anti-collision technology mainly uses an intelligent sensing system to quickly initiate automatic avoidance actions when a collision threat is detected. However, in extreme cases, especially when the impact force and impact speed exceed the upper limit of conventional protection, passive anti-collision technology cannot effectively avoid damage due to energy absorption limitations. The response speed of active anti-collision technology is limited by the detection efficiency of the sensor and the movement speed of the mechanical components. The time from the sensor identifying the collision signal to the mechanical components completing the avoidance action is not enough to avoid the collision, resulting in a reduced effectiveness of anti-collision measures and resulting in greater losses.

[0003] Existing anti-collision technology for charging piles has technical problems in that it cannot avoid damage in extreme collision situations due to insufficient response time or limited energy absorption. Utility Model Content

[0004] The purpose of the utility model is to provide a semi-buried charging pile to solve the technical problem in the related art that damage cannot be avoided due to insufficient response time or energy absorption limitation in extreme impact situations.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] The semi-buried charging pile provided by the utility model comprises:

[0007] A connecting component, an underground component and a charging component, wherein the connecting component includes a first joint, a second joint, a separation spring and a pin. The underground component is connected to the first joint, and the charging component is connected to the second joint. The first joint is detachably connected to the second joint, and the separation spring is installed between the first joint and the second joint in a compressed state. The pin is inserted into the first joint and the second joint at the same time to lock the first joint and the second joint; the pin can slide along its own axial direction to disengage from the second joint so that the separation spring separates the first joint from the second joint.

[0008] Specifically, the first joint is provided with a docking hole, and the second joint is inserted into the docking hole. The separation spring is inserted into the first joint and abuts against the second joint. The second joint is provided with a through hole in a vertical direction of the axis of the docking hole, and the pin penetrates the first joint and is inserted into the through hole.

[0009] Specifically, the connecting component also includes a secondary spring, one end of which is connected to the pin, and the other end of which is connected to the buried component, and is used to apply a thrust to the pin so that the pin is plugged into the second joint.

[0010] Specifically, the connection assembly also includes an electromagnet and a speed sensor, wherein the electromagnet is installed at one end of the secondary spring away from the pin. The pin is set to be a ferromagnetic material. The speed sensor is installed on the ground and is connected to the electromagnet control to detect the speed of the moving object.

[0011] Specifically, the buried component includes a buried box, a power supply unit, a control unit and a protection unit, wherein the power supply unit and the control unit are both installed in the buried box and connected to the first connector. The power supply unit is electrically connected to the charging component through the connecting component, and the control unit is electrically connected to the charging component through the connecting component.

[0012] Specifically, the charging assembly includes a housing, a charging gun, a charging cable, and an interactive interface. The charging gun is installed on the housing, the housing is sleeved on the charging cable and connected to the second connector, one end of the charging cable is connected to the second connector, and the other end is connected to the charging gun. The charging gun is electrically connected to the power supply unit through the connecting assembly, and the interactive interface is installed on the housing and electrically connected to the control unit through the connecting assembly.

[0013] Specifically, the charging assembly also includes a motor and a cable drum, wherein the motor is connected to the housing, the cable drum is mounted on the output shaft of the motor, and the charging cable is connected to the cable drum. The motor is used to drive the cable drum to rotate so as to retract and release the charging cable.

[0014] Specifically, the housing includes a shell and a cover. The charging gun and the interactive interface are installed in the shell, and the shell is provided with an operation window for taking and placing the charging gun and operating the interactive interface. The cover is movably connected to the shell to open and close the operation window.

[0015] Specifically, the charging assembly also includes a filling piece, which is arranged between the housing and the charging cable.

[0016] Specifically, the filling piece is made of an elastic material, and buffers the impact force borne by the charging assembly through elastic deformation.

[0017] Based on the above technical solutions, the beneficial effects of the present invention are analyzed as follows:

[0018] The utility model provides a semi-buried charging pile, comprising:

[0019] A connecting component, an underground component and a charging component, wherein the connecting component includes a first joint, a second joint, a separation spring and a pin. The underground component is connected to the first joint, and the charging component is connected to the second joint. The first joint is detachably connected to the second joint, and the separation spring is installed between the first joint and the second joint in a compressed state. The pin is inserted into the first joint and the second joint at the same time to lock the first joint and the second joint; the pin can slide along its own axial direction to disengage from the second joint so that the separation spring separates the first joint from the second joint.

[0020] In specific applications, when the charging assembly is hit, the separation spring between the first connector and the second connector is released from the compressed state, and the elasticity separates the first connector from the second connector, thereby separating the charging assembly from the buried assembly. The charging assembly is completely separated from the ground and flies out under the impact, and the buried assembly does not bear the impact. The impact force of the charging assembly is absorbed and dispersed by the flying action, reducing the damage to the charging equipment in the event.

[0021] It can be seen that compared with the existing technology, the charging component of the semi-buried charging pile is connected to the buried component through a detachable connecting component, and the impact force is absorbed and dispersed by making the charging component detach from the ground and fly out in the event of a collision, without energy absorption restrictions. This overcomes the technical problem that the existing charging pile anti-collision technology cannot avoid damage due to insufficient response time or energy absorption restrictions in extreme collision situations.

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] Existing anti-collision technology for charging piles has technical problems in that it cannot avoid damage in extreme collision situations due to insufficient response time or limited energy absorption.

[0038] In view of this, the utility model provides a semi-buried charging pile, comprising:

[0039] The connecting component 100, the buried component 200 and the charging component 300, the connecting component 100 includes a first joint 110, a second joint 120, a separation spring 130 and a pin 140. The buried component 200 is connected to the first joint 110, and the charging component 300 is connected to the second joint 120. The first joint 110 is detachably connected to the second joint 120, and the separation spring 130 is installed between the first joint 110 and the second joint 120 in a compressed state. The pin 140 is inserted into the first joint 110 and the second joint 120 at the same time to lock the first joint 110 and the second joint 120; the pin 140 can slide along its own axial direction to disengage from the second joint 120 so that the separation spring 130 separates the first joint 110 and the second joint 120, thereby separating the charging component 300 from the buried component 200.

[0040] Based on the above technical solutions, the semi-buried charging pile provided by the utility model can achieve the following technical effects:

[0041] The charging component 300 of the semi-buried charging pile is connected to the buried component 200 via a detachable connecting component 100, and the charging component 300 is separated from the ground 001 and flies out in the event of a collision to absorb and disperse the impact force, without energy absorption restrictions. This overcomes the technical problem that the existing charging pile anti-collision technology cannot avoid damage in extreme collision situations due to insufficient response time or energy absorption restrictions.

[0042] The following combination Figures 1 to 6 The structure and shape of the semi-buried charging pile provided in this embodiment are described in detail:

[0043] Regarding the structural composition of the connection component 100, specifically:

[0044] The connection assembly 100 includes a first joint 110 , a second joint 120 , a release spring 130 , a pin 140 , a secondary spring 150 , an electromagnet 160 , and a speed sensor 170 .

[0045] The first joint 110 is provided with a docking hole 101, which is a blind hole, and the second joint 120 is inserted into the docking hole 101. The separation spring 130 is inserted into the first joint 110 and abuts against the second joint 120. The second joint 120 is provided with a through hole 102 in a vertical direction of the axis of the docking hole 101. The pin 140 penetrates the first joint 110 and is inserted into the through hole 102 to lock the first joint 110 and the second joint 120. One end of the secondary spring 150 is connected to the pin 140, and the other end is connected to the buried component 200. The electromagnet 160 is installed at one end of the secondary spring 150 away from the pin 140. The pin 140 is set as a ferromagnetic material, which is used to apply a thrust to the pin 140 so that the pin 140 is inserted into the second joint 120. Among them, the ferromagnetic material of the pin 140 can be set as iron, carbon steel, nickel, etc. The electromagnet 160 is used to attract the pin 140 to overcome the elastic force of the secondary spring 150 to detach from the second connector 120. The speed sensor 170 is installed on the ground 001 and is connected to the control of the electromagnet 160 to detect the speed of the moving object. When the speed sensor 170 recognizes an object approaching at high speed, it is considered that a collision event has occurred. At this time, the electromagnet 160 is triggered to generate a magnetic field so that the pin 140 overcomes the elastic force of the secondary spring 150 and detaches from the second connector 120, thereby releasing the separation spring 130 to separate the first connector 110 and the second connector 120, thereby detaching the charging assembly 300 from the ground 001.

[0046] In the scheme of this embodiment, multiple speed sensors 170 are evenly distributed in a ring around the axis of the separation spring 130 and are all controlled and connected to the electromagnet 160. Any speed sensor 170 can trigger the electromagnet 160 to generate a magnetic field to attract the pin 140 and release the separation spring 130. The change of direction improves the triggering sensitivity of the electromagnet 160 in a collision event.

[0047] In the preferred solution of this embodiment, the charging assembly 300 includes an acceleration sensor, which is connected to the electromagnet 160 for detecting the acceleration data of the charging assembly 300. When the acceleration sensor detects the generation of an acceleration signal, it is determined that an impact event has occurred. At this time, the electromagnet 160 is triggered to generate a magnetic field so that the pin 140 overcomes the elastic force of the secondary spring 150 and detaches from the second joint 120, thereby releasing the separation spring 130 to separate the first joint 110 and the second joint 120, thereby detaching the charging assembly 300 from the ground 001. Any speed sensor 170 and acceleration sensor can trigger the electromagnet 160, further reducing the risk of the electromagnet 160 failing to trigger due to detection sensitivity problems in an impact event.

[0048] Regarding the structure of the buried component 200, specifically:

[0049] The buried component 200 includes a buried box 210, a power supply unit 220, a control unit 230 and a protection unit 240. The power supply unit 220 and the control unit 230 are both installed in the buried box 210 and connected to the first connector 110. The power supply unit 220 is electrically connected to the charging component 300 through the connecting component 100, the control unit 230 is electrically connected to the charging component 300 through the connecting component 100, and the protection unit 240 is installed in the buried box 210 and connected to the power supply unit 220, and is used to cut off the power supply of the power supply unit 220 when overload, short circuit or leakage occurs.

[0050] In the solution of this embodiment, the power supply unit 220, the control unit 230 and the protection unit 240 are arranged in the buried component 200 that does not withstand direct impact, which significantly reduces the risk of damage to the power supply unit 220, the control unit 230 and the protection unit 240, and further reduces the economic losses in the impact event.

[0051] Specifically, the power supply unit 220 includes a transformer, a current sensor, and a voltage sensor for transporting and distributing electric energy. The control unit 230 includes a microcontroller and a communication antenna for processing user interface interaction and controlling the charging logic of the power supply unit 220. The protection unit 240 includes an overload protector, a circuit breaker protector, a leakage protector, and a temperature sensor, which are respectively used to cut off the power supply of the power supply unit 220 when the charging pile line is overloaded, short-circuited, or leaks electricity.

[0052] Regarding the structural composition of the charging assembly 300, specifically:

[0053] The charging assembly 300 includes a housing 310, a charging gun 320, a charging cable 330, a motor 350, a cable drum 360, an electric slip ring, and an interactive interface 340. The charging gun 320 is installed in the housing 310, and the housing 310 is sleeved on the charging cable 330 and connected to the second connector 120. One end of the charging cable 330 is connected to the second connector 120, and the other end is connected to the charging gun 320. The charging gun 320 is electrically connected to the power supply unit 220 through the connecting assembly 100. The motor 350 is connected to the housing 310, and the cable drum 360 is installed on the output shaft of the motor 350. The charging cable 330 is connected to the cable drum 360 through an electric slip ring, and the motor 350 is used to drive the cable drum 360 to rotate to retract and release the charging cable 330. The interactive interface 340 is installed in the housing 310 and is electrically connected to the control unit 230 through the connecting assembly 100.

[0054] In order to prevent the charging gun 320 and the interactive interface 340 from directly colliding with the ground 001 after the charging component 300 is thrown out, in the scheme of this embodiment, the housing 310 includes a shell 311 and a cover 312. The charging gun 320 and the interactive interface 340 are installed in the shell 311, and the shell 311 is provided with an operation window 301 for taking and placing the charging gun 320 and operating the interactive interface 340. The cover 312 is movably connected to the shell 311 to open and close the operation window 301. The cover 312 is used to prevent the charging gun 320 and the interactive interface 340 from directly colliding with the ground 001 after the charging component 300 is knocked out. Among them, the cover 312 can be set as a flip cover, a sliding cover, a rotating cover, etc., and the movable connection mode with the shell 311 can be correspondingly set as a hinge, a sliding connection, a rotating connection, etc.

[0055] The charging gun 320, charging cable 330, motor 350, cable drum 360, electric slip ring and operation interaction interface 340 in the charging assembly 300 are functional components. In order to further ensure the functional integrity of the functional components after experiencing an impact event, in the solution of this embodiment, the charging assembly 300 also includes a filling piece, which is arranged between the shell 310 and the functional components, so that the shell 310 is used to concentrate the damage of the impact force to preserve the functional components, and the damage risk of the functional components is transferred to the shell 310.

[0056] In order to further reduce the interruption time and recovery cost of charging service after an incident, in the solution of this embodiment, the filling piece is detachably connected to the shell 310. When the shell 310 is damaged by an impact event, the original functional components can be retained and the spare shell 310 can be replaced, and the connection component 100 can be re-docking to quickly restore the charging service.

[0057] In an optional solution of this embodiment, the filling piece can be set to an elastic material to alleviate the damage to the functional component caused by the impact force through elastic deformation. The elastic material can be set to rubber, foam material, silicone, etc.

[0058] In an optional solution of this embodiment, the filler can be set as a filler of a non-Newtonian fluid. When subjected to the impact force of the collision, the viscosity of the non-Newtonian fluid increases, and it exhibits rigidity to absorb the impact energy and provide protection for the functional components. Even if it breaks under an impact exceeding the upper limit, the fragments of the non-Newtonian fluid exhibit flexibility due to the reduced viscosity, reducing sharp edges and penetration, thereby reducing the risk of secondary damage to the functional components.

[0059] In summary, the specific working process of the semi-buried charging pile provided in this embodiment is as follows:

[0060] Take the filling piece as an example, which is set to be an elastic material. The buried component 200 is connected to the charging component 300 through the connecting component 100. During daily charging, the cover 312 is flipped up to open the operation window 301. After operating the interactive interface 340, the charging gun 320 is taken out to complete the charging. After charging is completed, the motor 350 drives the cable drum 360 to reel in the charging cable 330, and then the cover 312 is flipped over to close the operation window 301.

[0061] The speed sensor 170 detects the speed of the surrounding moving objects in real time. When any speed sensor 170 detects that an object is approaching at high speed and there is no sign of deceleration, it is determined that a car collision event has occurred, triggering the electromagnet 160 to generate a magnetic field to apply magnetic attraction to the pin 140 to overcome the elastic force of the secondary spring 150. The pin 140 is separated from the second connector 120 to release the locking state between the first connector 110 and the second connector 120, thereby releasing the separation spring 130 to separate the first connector 110 and the second connector 120, thereby separating the charging assembly 300 from the ground 001, and finally the charging assembly 300 is hit by the car and flies out.

[0062] When the charging component 300 is hit by a car and flies out, the shell 310 flies out after being directly hit to absorb and disperse the impact force. The functional components dissipate the impact through the elastic deformation of the filling parts, and the shell 310 bears most of the risk of damage.

[0063] After the collision, the semi-buried charging pile is repaired and the charging service function is restored. When the shell 310 is not damaged, the second connector 120 can be directly inserted into the docking hole 101 of the first connector 110. When the shell 310 is damaged, the original functional components can be retained and the spare shell 310 can be replaced, and the second connector 120 can be inserted into the docking hole 101 of the first connector 110. At this time, the separation spring 130 is compressed, and the pin 140 is inserted into the through hole 102 under the elastic force of the secondary spring 150 to restore the locking state between the first connector 110 and the second connector 120.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
