Description

Technical Field

[0001] This utility model relates to the field of energy storage and charging equipment technology, specifically a mobile energy storage and charging vehicle. Background Technology

[0002] With the rapid development of electric vehicles and renewable energy technologies, the demand for mobile energy storage and charging equipment is increasing. Traditional charging equipment often relies on fixed power grid supply, which is inconvenient when used outdoors or in remote areas. Mobile energy storage charging vehicles primarily store electrical energy through onboard battery systems. When there is a charging need, the charging vehicle is driven to a designated location and connected to electric vehicles and other devices via a charging interface, transferring the stored electrical energy to the devices that need charging. It can utilize off-peak electricity hours for charging and provide charging services for various electric devices during peak electricity demand or emergencies.

[0003] Most existing mobile energy storage charging vehicles place multiple rows of battery racks containing energy storage batteries in the same compartment and minimize the gaps between the racks while meeting basic heat dissipation requirements. However, since there are no barriers between adjacent battery racks, when one energy storage battery becomes abnormally hot and spontaneously combusts, it can easily cause a chain reaction, resulting in all power sources burning simultaneously in a short period of time, which is unsafe. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile energy storage and charging vehicle, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a mobile energy storage and charging vehicle, including a vehicle body, a protective box is provided on the upper surface of the rear of the vehicle body, a lower hollow box is provided in the center of the bottom wall of the protective box, an energy storage box is fixedly connected to the top of the lower hollow box, an upper hollow box is fixedly connected to the top of the energy storage box, and a charging pile and a rescue tool box are respectively provided on both sides of the bottom wall of the protective box.

[0006] The energy storage box is equipped with battery racks evenly spaced along its length. The battery racks are equipped with energy storage batteries that are electrically connected to the charging pile. Rock wool heat insulation and flame retardant boards are installed between two adjacent battery racks.

[0007] The energy storage box is equipped with heat dissipation components on both sides of the battery rack for heat exchange and cooling of the air inside the energy storage box. The outer walls of the energy storage box are equipped with impact buffer components on both sides. The top wall of the energy storage box, above the battery rack, is equipped with fire-fighting components for extinguishing fires when the energy storage batteries are burning.

[0008] Preferably, the heat dissipation assembly includes heat dissipation pipes disposed inside the energy storage box on both sides of the battery rack for connecting the upper hollow box and the lower hollow box, air inlets opened on the protective box and the lower hollow box, and air outlets opened on the protective box and the upper hollow box. The air inlets opened on the protective box and the air inlets opened on the lower hollow box are connected by air inlet hoses, and the air outlets opened on the protective box and the air outlets opened on the upper hollow box are connected by air outlet hoses.

[0009] A filter screen is installed in the air inlet on the protective box, and a negative pressure fan is installed in the air outlet on the protective box.

[0010] Preferably, the impact buffer assembly includes multiple sets of sliding rods fixedly connected to both sides of the outer wall of the protective box. Each end of the sliding rod is fixedly connected to a fixed ring. The sliding rod is slidably connected to two movable rings between the two fixed rings. A spring is provided between the fixed rings and the movable rings. The outer walls of the two movable rings are rotatably connected to rotating rods. The ends of the two rotating rods away from the movable rings are rotatably connected to fixed rods. The ends of the fixed rods away from the rotating rods are fixedly connected to the inner wall of the protective box.

[0011] Preferably, a photovoltaic panel electrically connected to the energy storage battery is provided at the center of the upper surface of the protective box, and jacks are provided around the rear of the vehicle body.

[0012] Preferably, the fire-fighting component includes a smoke sensor disposed on the top wall of the energy storage box directly above the battery rack, and dry powder fire extinguishers electrically connected to the smoke sensor are disposed on both sides of the top wall of the energy storage box located above the battery rack.

[0013] Preferably, heat dissipation fins are provided on all four sides of the outer wall of the heat dissipation pipe, and support rods are evenly provided between the top wall and the bottom wall of the lower hollow box.

[0014] This utility model has the following beneficial effects:

[0015] This mobile energy storage and charging vehicle, through the cooperation of the vehicle body, protective box, lower hollow box, energy storage box, upper hollow box, battery racks, energy storage batteries, rock wool insulation and flame retardant board, and fire-fighting components, can effectively improve the safety of the device by extinguishing the fire as much as possible after the energy storage battery on one battery rack spontaneously combusts. This is because the rock wool insulation and flame retardant board can separate the adjacent battery racks, preventing the spontaneous combustion of the energy storage battery on the battery rack from quickly causing a chain reaction of fires on multiple battery racks. The fire-fighting components can also effectively extinguish the fire and prevent it from spreading after the energy storage battery on the battery rack spontaneously combusts.

[0016] This mobile energy storage and charging vehicle, through the cooperation of a sliding rod, a fixed ring, a movable ring, a spring, a rotating rod, and a fixed rod, when an external vehicle accidentally hits the protective box, the impacted part of the protective box deforms first, causing the fixed rod to move closer to the energy storage box. This, in turn, pushes the two rotating rods and the movable ring closer to the fixed ring, thereby compressing the spring and absorbing and buffering the impact force, thus minimizing the risk of the energy storage battery catching fire due to the impact force after the vehicle body is hit.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides a mobile energy storage and charging vehicle, including a vehicle body 1. A protective box 2 is provided on the upper surface of the rear of the vehicle body 1. Jacks 15 are provided on all four sides of the rear of the vehicle body 1. When the vehicle body 1 stops moving, the output end of the jacks 15 can be moved downward to touch the ground, thereby maximizing the stability of the vehicle when it stops moving and avoiding accidental impact that could cause the vehicle body 1 to overturn. A lower hollow box 3 is provided in the center of the bottom wall of the protective box 2. An energy storage box 4 is fixedly connected to the top of the lower hollow box 3. Support rods 16 are evenly provided between the top wall and the bottom wall of the lower hollow box 3. The support rods 16 can maximize the structural strength of the lower hollow box 3 and minimize the deformation of the lower hollow box 3 due to the excessive weight of the energy storage box 4.

[0026] The top of the energy storage box 4 is fixedly connected to the upper hollow box 5 and the protective box 2. Charging piles 6 and rescue tool boxes 7 are respectively installed on both sides of the bottom wall of the inner wall. Staff can put commonly used road rescue tools in the rescue tool box 7 so that they can use the road rescue tools in the rescue tool box 7 to provide road rescue for vehicles in case of accidents at any time.

[0027] Reference Figure 4 and Figure 5 Inside the energy storage box 4, battery racks 8 are evenly spaced along the length of the energy storage box 4. Energy storage batteries 9, which are electrically connected to the charging pile 6, are installed on the battery racks 8. Rock wool heat-insulating and flame-retardant boards 10 are installed between two adjacent battery racks 8. A photovoltaic panel 14, which is electrically connected to the energy storage batteries 9, is installed at the center of the upper surface of the protective box 2. When the photovoltaic panel 14 is exposed to sunlight, it can convert light energy into electrical energy to replenish the energy storage batteries 9, thereby effectively improving the battery life of the energy storage batteries 9. The installation of rock wool heat-insulating and flame-retardant boards 10 can separate the battery racks 8, which helps to maintain the independence between two adjacent battery racks 8 and prevents the energy storage batteries 9 on multiple battery racks 8 from rapidly catching fire due to abnormal high temperature when one of the battery racks 8 spontaneously combusts at high temperature.

[0028] Reference Figure 2 , Figure 4 and Figure 5The energy storage box 4 is equipped with heat dissipation components 11 on both sides of the battery rack 8 for heat exchange and cooling of the air inside the energy storage box 4. The heat dissipation components 11 include heat dissipation pipes 111 on both sides of the battery rack 8 inside the energy storage box 4 for connecting the upper hollow box 5 and the lower hollow box 3, air inlets 112 on the protective box 2 and the lower hollow box 3, and air outlets 113 on the protective box 2 and the upper hollow box 5. The air inlets 112 on the protective box 2 and the air inlets 112 on the lower hollow box 3 are connected by air inlet hoses 114, and the air outlets 113 on the protective box 2 and the air outlets 113 on the upper hollow box 5 are connected by air outlet hoses 115.

[0029] A filter 116 is installed in the air inlet 112 on the protective box 2, and a negative pressure fan 117 is installed in the air outlet 113 on the protective box 2. When the temperature of the energy storage battery 9 in the energy storage box 4 is high, the negative pressure fan 117 is turned on. The air outside the protective box 2 enters the lower hollow box 3 through the air inlet 112 and the air inlet hose 114, then flows through the heat dissipation pipe 111 into the upper hollow box 5, and is discharged to the external space of the protective box 2 through the air outlet hose 115 and the air outlet 113. When the outside air flows through the heat dissipation pipe 111, it exchanges heat with the air on both sides of the battery rack 8 through the pipe wall of the heat dissipation pipe 111, reducing the temperature of the air around the battery rack 8, thereby dissipating heat from the energy storage battery 9 on the battery rack 8. Heat dissipation fins 15 are provided around the outer wall of the heat dissipation pipe 111. The heat dissipation fins 15 can effectively increase the heat dissipation area between the heat dissipation pipe 111 and the air, thereby further improving the heat dissipation effect of the heat dissipation component 11.

[0030] The filter 116 can minimize the entry of dust and prevent it from adhering to the inner wall of the heat sink 111, thereby affecting the heat exchange efficiency when the airflow passes through the heat sink 111 wall and exchanges heat with the air on both sides of the battery rack 8.

[0031] Reference Figure 3 , Figure 4 and Figure 6 Impact buffer assemblies 12 are provided on both sides of the outer wall of the energy storage box 4. The impact buffer assembly 12 includes multiple sets of slide rods 121 fixedly connected to both sides of the outer wall of the protective box 2. Fixed rings 122 are fixedly connected to both ends of the slide rods 121. Two movable rings 123 are slidably connected between the two fixed rings 122. A spring 124 is provided between the fixed rings 122 and the movable rings 123. Rotating rods 125 are rotatably connected to the outer walls of the two movable rings 123. Fixed rods 126 are rotatably connected to the ends of the two rotating rods 125 away from the movable rings 123. The ends of the fixed rods 126 away from the rotating rods 125 are fixedly connected to the inner wall of the protective box 2.

[0032] When an external vehicle accidentally hits the protective box 2, the impacted part of the protective box 2 first deforms and drives the fixed rod 126 to move closer to the energy storage box 4, which in turn pushes the two rotating rods 125 and the movable ring 123 to move closer to the fixed ring 122, thereby compressing the spring 124 and absorbing and buffering the impact force.

[0033] Reference Figure 4 and Figure 5 The energy storage box 4 is equipped with fire-fighting components 13 above the battery rack 8 on the inner top wall for extinguishing fires when the energy storage battery 9 is burning. The fire-fighting components 13 include a smoke sensor 131 located on the inner top wall of the energy storage box 4 directly above the battery rack 8, and dry powder fire extinguishers 132 electrically connected to the smoke sensor 131 are installed on both sides of the inner top wall of the energy storage box 4 above the battery rack 8.

[0034] The charging pile 6, energy storage battery 9, negative pressure fan 117, smoke sensor 131 and dry powder fire extinguisher 132 are all electrically connected to the control panel (not shown in the figure). When the energy storage battery 9 malfunctions and produces smoke, the smoke sensor 131 detects the smoke and converts the smoke signal into an electrical signal, which is then transmitted to the dry powder fire extinguisher 132. This causes the dry powder fire extinguisher 132 to spray dry powder extinguishing agent onto the malfunctioning battery rack 8, thus minimizing the spread of the fire.

[0035] The working principle of this utility model is as follows:

[0036] When in use, first move the vehicle body 1 to the predetermined position, then move the output end of the jack 15 downwards to touch the ground, thereby maximizing the stability of the vehicle when it stops moving and avoiding accidental impacts that could cause the vehicle body 1 to overturn and the energy storage battery 9 on the battery rack 8 to tip over, creating a safety hazard. Then, the staff can use the charging pile 6 to charge the electric vehicle, or place commonly used road rescue tools in the rescue toolbox 7 so that they can be used at any time to provide road rescue for the vehicle in case of an accident. When the photovoltaic panel 14 is exposed to sunlight, it can convert light energy into electrical energy to replenish the energy storage battery 9, thereby effectively improving the battery life of the energy storage battery 9.

[0037] When an external vehicle accidentally hits the protective box 2, the impacted part of the protective box 2 first deforms and drives the fixed rod 126 to move closer to the energy storage box 4, which in turn pushes the two rotating rods 125 and the movable ring 123 to move closer to the fixed ring 122, thereby compressing the spring 124 and absorbing and buffering the impact force.

[0038] By using rock wool insulation and flame retardant panels 10 to separate the battery racks 8, it helps to maintain the independence between two adjacent battery racks 8, and avoids a chain reaction caused by the abnormal high temperature and spontaneous combustion of the energy storage batteries 9 on one of the battery racks 8. At the same time, when the energy storage battery 9 abnormally produces smoke, the smoke sensor 131 detects the smoke and converts the smoke signal into an electrical signal, which is then transmitted to the dry powder fire extinguisher 132. This causes the dry powder fire extinguisher 132 to spray dry powder extinguishing agent onto the abnormal battery rack 8, thus minimizing the spread of the fire.

[0039] When the temperature of the energy storage battery 9 inside the energy storage box 4 is high, the negative pressure fan 117 is turned on. The air outside the protective box 2 enters the lower hollow box 3 through the air inlet 112 and the air inlet hose 114, then flows through the heat dissipation pipe 111 into the upper hollow box 5, and is then discharged to the external space of the protective box 2 through the air outlet hose 115 and the air outlet 113. When the outside air flows through the heat dissipation pipe 111, it exchanges heat with the air on both sides of the battery rack 8 through the pipe wall and heat dissipation fins 15 of the heat dissipation pipe 111, thereby reducing the temperature of the air around the battery rack 8 and thus dissipating heat from the energy storage battery 9 on the battery rack 8.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
