Description

Technical Field

[0001] The present invention belongs to the field of new energy technology, and particularly relates to a mobile energy storage charging pile. Background Art

[0002] Since existing high-voltage DC charging piles have a large instantaneous demand on the power grid, they may affect the stability of the power grid, especially when the power grid capacity is limited or during peak load periods. These problems lead to contradictions in the charging demand for new energy batteries in highway service areas, shopping malls, and old communities.

[0003] Mobile energy storage charging piles can store electricity during low-consumption periods and release it during peak-consumption periods, thereby meeting electricity demand during peak-consumption periods.

[0004] Existing mobile energy storage charging piles cannot be quickly charged for secondary operation after a single discharge, and cannot be quickly dispatched to different regions based on peak electricity consumption.

[0005] Therefore, a mobile energy storage charging pile with replaceable batteries is proposed to ensure continuous discharge of the charging pile during peak power consumption periods and facilitate regional energy scheduling. Summary of the Invention

[0006] The purpose of the present invention is to provide a mobile energy storage charging pile, which can extend the working time of the charging pile by quickly replacing the battery of the charging pile, and facilitate the regional scheduling of energy.

[0007] The technical solutions adopted by the present invention are as follows:

[0008] A mobile energy storage charging pile includes a vehicle frame, a hub motor wheel for driving the vehicle frame to move is provided at the bottom of the vehicle frame, and an infrared acquisition camera for controlling the movement of the vehicle frame is provided at the top of the vehicle frame;

[0010] An air compression group and an air tank are provided in the vehicle body frame, and the air tank is connected to each air spring through a distribution valve;

[0011] The air spring is provided with an air pressure sensor;

[0012] The first anti-collision shell is elastically supported by the air spring, so that the first anti-collision shell is in a stable state under normal circumstances. When the vehicle frame collides, the first anti-collision shell contacts the collision object first and slides as a whole, thereby causing the air pressure of the air spring between the vehicle frame and the first anti-collision shell to change, thereby confirming the collision position and driving the hub motor wheel to quickly drive to avoid it.

[0013] A support frame is provided inside the first anti-collision shell, and a second anti-collision shell is provided on the outside of the vehicle body frame. One side of the air spring is fixedly connected to the second anti-collision shell, and the other side of the air spring is fixedly connected to the first anti-collision shell. When the first anti-collision shell is displaced as a whole due to a collision, the air pressure of the air spring on the collision side is increased, and the air pressure of the air spring away from the collision side is reduced due to tension.

[0014] The air spring is provided with a pressure relief valve, which operates when the air spring is subjected to a pressure exceeding its operating threshold;

[0015] The air springs are symmetrically distributed, and the forces exerted on the first anti-collision shell by the air springs on both sides of the vehicle body frame offset each other, and the pressure inside each air spring is equal.

[0016] The positions of the air compression group, the gas tank and the radiator correspond to each other. When the air compression group and the gas tank are hit, the air compression group and the gas tank collapse toward the inside of the radiator.

[0017] The vehicle frame is provided with a plurality of battery compartments, each of which contains batteries. A battery management component and a voltage regulating component are provided on the vehicle frame. An electrically controlled hinge plate is hingedly connected to the position of the limiting plate corresponding to the battery.

[0018] A clamping hole is provided in the middle of the top of the battery, and a positioning hole is provided on the top of the battery;

[0019] The bottom of the battery is provided with a socket, and the bottom of the battery is provided with a supporting foot;

[0020] The battery compartments are arranged in opposite directions, and the battery compartments are located on both sides of the vehicle body frame. A radiator is arranged between the battery compartments.

[0021] The battery compartment includes a battery heat dissipation shell, a limiting clamping plate is provided on a side of the battery heat dissipation shell away from the radiator, a guide block is fixedly connected to the bottom of the limiting clamping plate, a guide groove 1 is provided at a position of the battery heat dissipation shell corresponding to the guide block, two circular protrusions are provided on the guide block, and the top of the guide groove 1 is connected to the guide groove 2, a spring is provided between the guide block and the battery heat dissipation shell, the spring applies an upward force to the limiting clamping plate as a whole, and a traction plate is provided on the bottom of the limiting clamping plate facing the battery heat dissipation shell;

[0022] The battery heat dissipation shell is provided with a plurality of heat pipes, and the battery heat dissipation shell is made of heat-conducting material.

[0023] The top of the radiator is connected to an air inlet, and the cooling fins of the radiator are distributed longitudinally.

[0024] A power connection device is provided at the bottom of the vehicle body frame, and the power connection device includes an on-off shaft, and the on-off shaft is rotatably and slidably connected to the bottom of the vehicle body frame, and both ends of the on-off shaft are hinged with a, and the end away from the swing plate is hinged with a, which is fixedly connected to the first anti-collision shell;

[0025] The on-off shaft is fixedly connected to a gear 1, the on-off shaft is slidably connected to a transmission wheel, the bottom of the vehicle body frame is fixedly connected to a stepper motor, and the stepper motor is connected to the transmission wheel through a belt;

[0026] A plug is slidably connected to the bottom of the vehicle body frame, a screw rod is provided on one side of the plug, one end of the screw rod is fixedly connected to gear 2, and a torsion spring is provided at one end of the screw rod. Gear 2 corresponds to the middle part of gear 1 under normal conditions.

[0027] The technical effects achieved by the present invention are:

[0028] In the present invention, when the mobile energy storage charging pile collides with a collision object, the air spring on the collision side is squeezed, and the air spring with increased air pressure is inflated through the air tank and the distribution valve to offset part of the impact force of the collision object.

[0029] The present invention simulates collisions at various locations on the first crashproof housing and collects data on the air pressure changes in the air springs on each side. This data is then compared with the actual collision data to determine the impact location of the mobile energy storage charging station, thereby facilitating control of the in-wheel motor wheel operation for rapid avoidance.

[0030] In the present invention, after the battery is discharged, the vehicle frame is brought into the battery swap station, and the clamping head is positioned through the positioning hole until the clamping head extends into the clamping hole, so that the battery is pulled out as a whole, and the battery is replaced, thereby extending the working time of the mobile energy storage charging pile.

[0031] According to the present invention, when the first anti-collision shell is impacted, it will slide as a whole, and the swing plates and support plates on both sides of the on-off shaft will push and guide the on-off shaft as a whole, until the engagement between gear 2 and gear 1 is disengaged. At this time, the screw rod disengages the plug from the socket under the reverse rotation of the torsion spring, thereby disconnecting the circuit of the pair of batteries and avoiding leakage.

[0032] In this invention, the heat sink has a thin fin with a gap in the middle. Therefore, when the heat sink is impacted, the fin will bend. As a result, when the battery is impacted, the heat sink can collapse, allowing the battery to deflect a small distance, thereby absorbing the impact force of the battery.

[0033] The present invention modularizes the battery to facilitate cross-regional transportation of the battery, thereby coping with the increased demand for electricity in holiday service areas. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0050] like Figure 1-10 As shown, a mobile energy storage charging pile includes a body frame 1, a hub motor wheel 2 for driving the body frame 1 to move is provided at the bottom of the body frame 1, and an infrared acquisition camera 11 for controlling the movement of the body frame 1 is provided at the top of the body frame 1;

[0051] A limit plate 13 is provided on the top of the vehicle body frame 1, a limit plate 2 14 is provided on the bottom of the vehicle body frame 1, a first anti-collision shell 10 is provided between the limit plate 13 and the limit plate 2 14, and a plurality of air springs 3 are provided between the vehicle body frame 1 and the first anti-collision shell 10;

[0052] An air compression group 4 and an air tank 5 are provided in the vehicle body frame 1. The air tank 5 is connected to each air spring 3 through a distribution valve.

[0053] An air pressure sensor is provided on the air spring 3;

[0054] The first anti-collision shell 10 is elastically supported by the air spring 3, so that the first anti-collision shell 10 is in a stable state under normal circumstances. When the vehicle frame 1 collides, the first anti-collision shell 10 contacts the collision object first and slides as a whole, thereby causing the air pressure of the air spring 3 between the vehicle frame 1 and the first anti-collision shell 10 to change, thereby confirming the collision position and driving the hub motor wheel 2 to quickly drive to avoid it.

[0055] According to the above structure, since the in-wheel motor wheel 2 has a short response time and the rotation speed and direction can be independently controlled, and the working environment of the mobile energy storage charging pile is mostly low-speed vehicles, when a vehicle collides with the mobile energy storage charging pile, the first anti-collision shell 10 will slide between the limit plate 13 and the limit plate 2 14, and can squeeze the air spring 3 on the collision side. According to the pressure difference of the air spring 3 on the collision side, the collision position of the first anti-collision shell 10 is determined, and the operation of each in-wheel motor wheel 2 is controlled accordingly, so as to separate the mobile energy storage charging pile from the collision object and prevent the battery in the mobile energy storage charging pile from being burned by the impact;

[0056] When the mobile energy storage charging pile collides with an object, the air spring 3 on the collision side is squeezed, and the air spring 3 with increased air pressure is inflated through the gas tank 5 and the distribution valve to offset part of the impact force of the collision object.

[0057] Furthermore, the hub motor integrates the motor directly into the wheel. The fixed part of the hub motor is equipped with the motor, and the rotating part is equipped with a permanent magnet. The speed is controlled by the input current size or frequency, and the rotation direction is controlled by the direction of the input current. Each wheel of the hub motor can be controlled independently, and the control ability is stronger. The mobile energy storage charging pile can achieve mobile control of the mobile energy storage charging pile by controlling the rotation direction and rotation speed of each wheel.

[0058] Furthermore, the first anti-collision shell 10 is divided into blocks, so that after the first anti-collision shell 10 is broken by a collision, it can be replaced more conveniently and the replacement cost can be reduced.

[0059] Refer to the attached Figure 1 and attached Figure 5 A support frame is provided inside the first anti-collision shell 10, and a second anti-collision shell 20 is provided on the outside of the vehicle body frame 1. One side of the air spring 3 is fixedly connected to the second anti-collision shell 20, and the other side of the air spring 3 is fixedly connected to the first anti-collision shell 10. When the first anti-collision shell 10 is displaced as a whole due to a collision, the air pressure of the air spring 3 on the collision side is increased, and the air spring 3 away from the collision side is pulled and the air pressure decreases.

[0060] According to the above structure, a simulated collision can be performed on each position of the first anti-collision shell 10 in advance, and data on the air pressure changes of the air springs 3 on each side can be collected for comparison with the data of the actual collision, so as to confirm the impact position of the mobile energy storage charging pile, thereby facilitating the control of the operation of the hub motor wheel 2 and performing quick avoidance.

[0061] The air spring 3 is provided with a pressure relief valve, which operates when the air spring 3 is subjected to a pressure exceeding its operating threshold;

[0062] The air springs 3 are symmetrically distributed, and the forces exerted by the air springs 3 on both sides of the vehicle body frame 1 on the first anti-collision shell 10 cancel each other, and the pressure in each air spring 3 is equal.

[0063] According to the above structure, when the vehicle speed is too fast and collides with the first anti-collision shell 10, the air pressure of the air spring 3 increases rapidly per unit time. When the air pressure exceeds the safety threshold, the pressure relief valve works to reduce the air pressure of the air spring 3.

[0064] Furthermore, an airbag may be provided between the first anti-collision shell 10 and the vehicle body frame 1 . When the pressure relief valve is working, the airbag is activated to offset part of the impact force, thereby protecting the battery 21 .

[0065] Refer to the attached Figure 3 The positions of the air compression group 4 , the gas tank 5 and the radiator 15 correspond to each other. When the air compression group 4 and the gas tank 5 are hit, the air compression group 4 and the gas tank 5 collapse toward the inside of the radiator 15 .

[0066] According to the above structure, when the side of the mobile energy storage charging pile close to the air compression group 4 is hit, the air compression group 4 and the gas tank 5 will be squeezed toward the radiator 15, thereby preventing the air compression group 4 and the gas tank 5 from directly squeezing the battery 21 and causing a short circuit of the battery 21.

[0067] Refer to the attached Figure 6 and attached Figure 7 The vehicle body frame 1 is provided with a plurality of battery compartments 8, in which batteries 21 are provided. The vehicle body frame 1 is provided with a battery management component 6 and a voltage regulating component 7. The position of the limiting plate 13 corresponding to the position of the battery 21 is hinged with an electric control hinge plate 19;

[0068] A clamping hole 22 is provided in the middle of the top of the battery 21, and a positioning hole 23 is provided on the top of the battery 21;

[0069] The bottom of the battery 21 is provided with a socket 24 and a supporting foot 25;

[0070] The battery compartments 8 are arranged in opposing relation, and the battery compartments 8 are located on both sides of the vehicle body frame 1 , and a radiator 15 is provided between the battery compartments 8 .

[0071] Furthermore, the battery 21 may be composed of recycled batteries from new energy vehicles. As the sales of new energy vehicles increase, the demand for charging gradually increases, and recycled batteries can be used to alleviate the charging demand of new electric vehicles.

[0072] Furthermore, the battery swap station consists of a storage warehouse and a battery swap warehouse. The battery storage warehouse is used to store modular batteries, and the battery swap warehouse is used to replace batteries in mobile energy storage charging piles. The storage warehouse and the battery swap warehouse are connected by a battery conveying rail. The battery swap warehouse is equipped with a variety of positioners, three-axis guide rails, and internal expansion clamps. The internal expansion clamp is placed on the working part of the three-axis guide rail. The positioner is used to control the operation of the three-axis guide rail and the internal expansion clamp.

[0073] Furthermore, an annular groove is provided in the clamping hole 22, and the internal expansion clamp of the battery swap compartment can be quickly fixed by engaging with the groove and the positioning hole 23.

[0074] Furthermore, a guide surface is provided at the top of the positioning hole 23 to position and guide the positioning pin of the internal expansion clamp of the battery swap station, thereby reducing the movement accuracy requirements of the internal expansion clamp and reducing the overall cost of the battery swap station.

[0075] According to the above structure, when the battery 21 is discharged, the vehicle frame 1 is brought into the battery swap station, and the clamping head is positioned through the positioning hole 23 until the clamping head extends into the clamping hole 22, so that the battery 21 is pulled out as a whole, and the battery 21 is replaced. The pull-up replacement simplifies the structure of the battery swap station, reduces the cost of the battery swap station, and effectively improves work efficiency.

[0076] Refer to the attached Figure 7 and attached Figure 8 The battery compartment 8 includes a battery heat dissipation housing 801. A limiting clamp 803 is provided on the side of the battery heat dissipation housing 801 away from the radiator 15. A guide block 804 is fixedly connected to the bottom of the limiting clamp 803. A guide groove 1 807 is provided at a position of the battery heat dissipation housing 801 corresponding to the guide block 804. Two circular protrusions with a gap are provided on the guide block 804. The top of the guide groove 1 807 is connected to the guide groove 2 805. A spring 806 is provided between the guide block 804 and the battery heat dissipation housing 801. The spring 806 applies an upward force to the limiting clamp 803 as a whole. A traction plate 808 is provided on the bottom of the limiting clamp 803 facing the battery heat dissipation housing 801.

[0077] The battery heat dissipation housing 801 is provided with a plurality of heat pipes 802 , and the battery heat dissipation housing 801 is made of heat-conducting material.

[0078] When the battery 21 is not placed in the battery compartment 8, the limiting clamp 803 slides upward under the pull of the spring 806 through the guidance of the guide groove 2 805 and the guide groove 1 807, and then deflects at a small angle, so that the limiting clamp 803 is deflected and protruded upward, so that the battery 21 under the expansion clamp in the battery swap station can be laterally aligned through the limiting clamp 803, and then the battery 21 is transported to the battery heat dissipation shell 801 along the guidance of the limiting clamp 803 under the joint operation of the three-axis guide rail. After the bottom of the battery 21 contacts the traction plate 808 at the bottom of the limiting clamp 803, the limiting clamp 803 slides downward under the pressure of the battery 21, and when the circular protrusion of the guide block 804 is between the hinge of the guide groove 2 805 and the guide groove 1 807, the battery 21 is pushed toward the battery heat dissipation shell 801 to ensure the installation of the battery 21.

[0079] Furthermore, the traction plate 808 and the bottom of the battery 21 are provided with corresponding bosses.

[0080] Refer to the attached Figure 3 The top of the radiator 15 is connected to the air inlet 12, and the cooling fins of the radiator 15 are distributed longitudinally.

[0081] According to the above structure, since the battery 21 generates a large amount of heat during discharge, in order to ensure the stability of battery discharge, the heat generated by the battery 21 needs to be guided. Therefore, the heat pipe 802 on the surface of the battery heat dissipation shell 801 is used to ensure the uniformity of the overall temperature of the battery heat dissipation shell 801, thereby achieving the goal of guiding the heat generated by the battery 21 inside the battery heat dissipation shell 801 to the radiator 15.

[0082] Furthermore, a dustproof net 26 is provided at the bottom of the radiator 15, and dustproof plates 16, rainproof plates 17, and fans 18 are provided on both sides of the air inlet 12 from outside to inside.

[0083] The dustproof plate 16 is used to prevent dust. The dustproof plate 16 is placed on the top of the mobile energy storage charging pile to facilitate subsequent maintenance;

[0084] The rain shield 17 is used to prevent rainwater from entering the air duct;

[0085] The fan 18 is used to input airflow into the radiator 15 .

[0086] Furthermore, a cold zone delivery port is provided in the working chamber of the battery management component 6 and the voltage regulating component 7, and the heat sink fins of the radiator 15 are distributed horizontally on the side close to the battery management component 6, so as to facilitate the guidance of the airflow in the battery management component 6.

[0087] Furthermore, because the heat sink 15 has a gap in the middle and the heat sink is thin, when the heat sink 15 is impacted, the heat sink will bend. As a result, when the battery 21 is impacted, the heat sink 15 can collapse, allowing the battery 21 to deflect a small distance, thereby absorbing the impact force of the battery 21.

[0088] Refer to the attached Figure 1 and attached Figures 9 to 10 A power connection device 9 is provided at the bottom of the vehicle body frame 1. The power connection device 9 includes an on-off shaft 901. The on-off shaft 901 is rotatably and slidably connected to the bottom of the vehicle body frame 1. Both ends of the on-off shaft 901 are hinged with a swing plate 910. The end of the swing plate 910 away from the on-off shaft 901 is hinged with a support plate 903. The support plate 903 is fixedly connected to the first anti-collision shell 10.

[0089] A gear 1 902 is fixedly connected to the on-off shaft 901, and a transmission wheel 905 is slidably connected to the on-off shaft 901. A stepper motor 904 is fixedly connected to the bottom of the vehicle frame 1, and the stepper motor 904 is connected to the transmission wheel 905 through a belt.

[0090] A plug 906 is slidably connected to the bottom of the vehicle body frame 1, a screw rod 907 is provided on one side of the plug 906, one end of the screw rod 907 is fixedly connected to gear 2 908, and a torsion spring 909 is provided on one end of the screw rod 907. Gear 2 908 corresponds to the middle part of gear 1 902 under normal conditions.

[0091] According to the above structure, when the battery 21 is installed, the stepper motor 904 drives the transmission wheel 905, the on-off shaft 901, and the transmission wheel 905 to rotate, and the gear 1 902 drives the gear 2 908 and the screw rod 907 to rotate, thereby engaging the plug 906 with the socket 24 to realize the series connection of the battery 21.

[0092] At the same time, since the batteries 21 are located on both sides of the mobile energy storage charging pile, when both sides of the mobile energy storage charging pile are subjected to a positive impact, the probability of damage to the batteries 21 increases and the risk of leakage increases. Therefore, when only one side of the two sides is impacted, the battery 21 needs to be powered off. When impacted, the first anti-collision shell 10 will slide as a whole after the impact, and through the pushing and guidance of the swing plates 910 and the support plates 903 on both sides of the on-off shaft 901, the on-off shaft 901 is driven to slide as a whole until the gear 2 908 is disengaged from the gear 1 902. At this time, the screw rod 907 disengages the plug 906 from the socket 24 under the reverse reversal of the torsion spring 909, thereby realizing the circuit disconnection of the pair of batteries 21.

[0093] Furthermore, a guide rod is provided on one side of the plug 906 to ensure the stability of the movement of the plug 906.

[0094] Furthermore, the width of the gear 1 902 is smaller than twice the maximum lateral movement distance of the first anti-collision shell 10 minus the width of the gear 2 908 .

[0095] The working principle of the present invention is as follows: since the in-wheel motor wheel 2 has a short response time and the rotation speed and direction can be independently controlled, and the working environment of the mobile energy storage charging pile is mostly low-speed vehicles, when a vehicle collides with the mobile energy storage charging pile, the first anti-collision shell 10 will slide between the limiting plate 13 and the limiting plate 2 14, and can squeeze the air spring 3 on the collision side. The collision position of the first anti-collision shell 10 is determined according to the pressure difference of the air spring 3 on the collision side, and the operation of each in-wheel motor wheel 2 is controlled accordingly, so that the mobile energy storage charging pile is separated from the collision object, thereby preventing the battery 21 in the mobile energy storage charging pile from being impacted and burning.

[0096] When the battery 21 has completed discharging, the vehicle frame 1 is brought into the battery swap station, and the clamping head is positioned through the positioning hole 23 until the clamping head extends into the clamping hole 22. The battery 21 is thereby pulled out as a whole, and the battery 21 is replaced, thereby extending the working time of the mobile energy storage charging pile. At the same time, the detachable battery 21 facilitates cross-regional transportation of the battery 21 to meet the emergency power needs of a single local area.

[0097] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
