Technical Field

[0001] The present invention relates to the field of energy storage charging, and particularly to a portable mobile energy storage charging robot. Background Art

[0002] With the development of society and the progress of the times, more and more electronic and electrical devices have emerged in people's lives, and people's dependence on electricity has also become higher and higher. Therefore, the stability and reliability of power supply are of crucial importance; with the acceleration of energy transformation and the continuous progress of energy storage technology, energy storage charging technology has gradually matured. Energy storage charging technology can be used as a backup power supply and can become the key to ensuring the normal operation of critical equipment in emergencies such as power grid failures and power outages, reducing economic losses and social impacts caused by power outages. At the same time, it can also store electrical energy during low electricity consumption periods through the energy storage charging system and use it during peak periods, thereby reducing electricity costs and effectively improving electricity efficiency and reducing electricity costs.

[0003] At present, with the improvement of people's living standards, the ownership of electric vehicles and the frequency of outdoor activities have gradually increased, and the demand for portable energy storage charging devices has also been growing; for example, in scenarios such as camping and self-driving tours, people need portable and easy-to-use energy storage charging devices to provide power support for electronic devices, lighting devices, and transportation tools; however, most of the existing energy storage charging devices are large-sized non-mobile ones, and such non-mobile energy storage charging devices are greatly restricted by the regionality of power supply and are inconvenient to carry, which greatly limits the practicality and universality of the application of the energy storage charging system and causes great inconvenience to people's daily life; moreover, due to the small volume of the existing mobile energy storage robots, most of their internal heat dissipation systems use air cooling for heat dissipation, with low heat dissipation efficiency and poor effects. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background art and provide a portable mobile energy storage charging robot, which is small in volume and convenient to carry. A liquid cooling system for use in battery charging and discharging is also equipped in the internal battery pack, which can effectively perform liquid cooling heat dissipation on the battery pack, making the energy storage effect of the portable mobile energy storage charging robot better.

[0005] The above technical object of the present invention is achieved through the following technical solutions: A portable mobile energy storage charging robot, comprising a vehicle body, and the interior of the vehicle body includes a plurality of battery pack compartments, a motor compartment, and a module compartment; each of the battery pack compartments is provided with a battery pack, the motor compartment is provided with a liquid chiller and a PCS bidirectional inverter, the upper layer of the module compartment is provided with a vision detection module, and the lower layer is also provided with a drive module; a battery pack is arranged inside the battery pack box body, the battery pack is composed of a plurality of battery cells electrically connected, a certain gap is arranged between each of the battery cells for heat dissipation, and a heat conduction plate is further arranged at the bottom of the battery pack; the bottom plate of the battery pack box body is a liquid-cooled heat dissipation plate, and the heat conduction plate is arranged above the liquid-cooled heat dissipation plate.

[0006] Preferably, a battery pack is arranged inside the battery pack box body, the battery pack is composed of a plurality of battery cells electrically connected, a certain gap is arranged between each of the battery cells for heat dissipation, and a heat conduction plate is further arranged at the bottom of the battery pack; gaps are arranged between the plurality of battery cells in the battery pack, so that the heat generated by the battery cells during operation will not be too concentrated, resulting in difficult heat dissipation. The heat conduction structure design of the heat conduction plate at the bottom of the battery pack can better transfer the heat of the battery pack to the liquid-cooled plate at the bottom of the heat conduction plate, making the heat dissipation effect better.

[0007] Preferably, the heat conduction plate is provided with an upper layer and a lower layer, and the upper layer and the lower layer are supported and connected by a plurality of support columns; the upper layer and the lower layer of the heat conduction plate are supported and connected by a plurality of support columns, so that the heat conduction plate can bear the weight of the battery pack on the heat conduction plate. The upper layer of the heat conduction plate can absorb the heat generated by the battery cells in the battery pack and transfer it to the lower layer of the heat conduction plate, and then the lower layer of the heat conduction plate will transfer the heat to the liquid-cooled plate and dissipate the heat through the liquid-cooled water.

[0008] Preferably, the top of the upper layer of the heat conduction plate is a heat conduction top cover, and a layer of top liquid absorption core is fixedly arranged below the heat conduction top cover; the lower layer of the heat conduction plate is sequentially provided with a bottom liquid absorption core and a heat conduction bottom cover, and the bottom liquid absorption core is fixedly connected to the heat conduction bottom cover; the heat conduction top cover and the heat conduction bottom cover of the heat conduction plate are made of copper plates with excellent heat conduction performance. Using the good heat conduction performance of copper, the heat generated by the battery cells of the battery pack can be quickly conducted out, preventing heat accumulation from causing too high heat in the battery pack.

[0009] Preferably, the surfaces of the top liquid absorption core and the bottom liquid absorption core are relatively rough. The interior of the liquid absorption core contains abundant capillary pores, and the liquid absorption core contains a cooling liquid for cooling. The top liquid absorption core and the bottom liquid absorption core are formed by sintering copper powder through a specific process. Abundant capillary pores are formed between the copper powders, which can provide good capillary force for the cooling liquid inside the liquid absorption core, enabling the cooling liquid to flow and circulate smoothly therein, making heat transfer more efficient. When the battery pack works, the heat generated is absorbed by the heat conduction top cover of the heat conduction plate. After absorbing the heat, the heat conduction top cover transfers the heat to the top liquid absorption core. The cooling liquid contained in the top liquid absorption core vaporizes into steam when heated. The steam diffuses to the bottom liquid absorption core with a lower temperature under the action of air pressure. When the steam reaches the bottom liquid absorption core, it condenses into a liquid and transfers the heat to the heat conduction bottom cover through the bottom liquid absorption core and then transfers it out. Finally, the heat is dissipated through the liquid cooling water in the liquid cooling plate under the heat conduction bottom cover to complete the liquid cooling of the battery pack. The liquid condensed from the steam will finally flow back through the capillary effect to form a cycle in the heat conduction plate.

[0010] Preferably, the surfaces of the top liquid absorption core and the bottom liquid absorption core are relatively rough. The rough surface of the liquid absorption core is equivalent to forming more tiny capillary pores, and the radius of these capillary pores is smaller, thereby enhancing the capillary force of the cooling liquid, which can make the cooling liquid more easily flow back from the condensed bottom liquid absorption core at the bottom layer to the top liquid absorption core at the upper layer, ensuring the circulation of the cooling liquid in the heat conduction plate and making the heat transfer and conduction of the heat conduction plate more efficient.

[0011] Preferably, the heat conduction bottom cover of the heat conduction plate is arranged on the liquid cooling plate. Liquid cooling inlets and liquid cooling outlets are arranged at both ends of the liquid cooling plate. The liquid cooling inlets and the liquid cooling outlets are connected through the liquid cooling circulation pipelines buried in the heat conduction plate. After the heat conduction plate absorbs the heat of the battery pack, it transfers the heat to the liquid cooling plate through the heat conduction bottom cover. The liquid cooling circulation pipelines are buried in the liquid cooling plate. The liquid cooling water in the pipelines continuously circulates and flows to take away the heat of the battery pack. The liquid cooling inlets and the liquid cooling outlets arranged at both ends of the liquid cooling plate connect the liquid cooling circulation pipelines to form a closed loop for the liquid cooling circulation.

[0012] Preferably, a number of pipeline bends are arranged on the liquid cooling circulation pipeline to increase the contact area with the heat conduction bottom cover. Increasing the number of pipeline bends on the liquid cooling circulation pipeline can increase the contact area with the heat conduction bottom cover of the heat conduction plate, making the heat dissipation efficiency higher and the heat dissipation effect better.

A number of branches are provided on the liquid cooling outlet pipe and are respectively communicated with the liquid cooling inlets on the liquid cooling radiating plates. A number of branches are provided on the liquid cooling return pipe and are respectively communicated with the liquid cooling outlets on the liquid cooling radiating plates. The liquid cooling radiating plates of each battery pack are respectively connected to the liquid cooling outlet pipe and the liquid cooling return pipe, so that the liquid cooling water can enter the liquid cooling radiating plates to take away heat and then take the heat out of the battery pack through the liquid cooling return pipe, enabling continuous cooling of the battery pack. The reciprocating cycle keeps the battery pack at a relatively low temperature all the time, making the energy storage charging robot more stable and reliable.

[0014] Preferably, a visual acquisition probe is provided on the vehicle body and is electrically connected to the visual detection module. A number of ranging radars are also provided around the sides of the vehicle body and are electrically connected to the visual detection module. A lighting device is further provided below the visual acquisition probe. The visual acquisition probe can collect the surrounding environmental information during the movement of the energy storage charging robot. Moreover, a number of ranging radars are provided around the sides of the vehicle body, enabling the robot to keep a distance from the objects in the surrounding environment during movement and preventing collisions, ensuring the safety and reliability during the movement of the robot. A lighting device is also provided below the vehicle body, enabling the robot to work normally at night or under poor lighting conditions.

[0015] Preferably, a number of wheels for the movement of the robot are provided at the bottom of the vehicle body. The driving module can control the movement of the robot. A handle is also provided on the upper part of the vehicle body. The wheels at the bottom of the vehicle body enable the energy storage charging robot to move normally. The driving module can control the movement of the robot. The handle on the upper part of the vehicle body enables people to intervene in the activities of the robot.

[0016] Preferably, a charging device is provided on the vehicle body. The charging device is connected with a charging gun for charging external devices through a charging cable. The charging cable is wound and fixed by a cable reel. A charging port for charging the robot is also provided on the vehicle body. The charging device, the charging port, the PCS bidirectional converter and the battery pack are all electrically connected. The charging port of the energy storage charging robot enables external charging devices to charge the energy storage charging robot. The charging device on the vehicle body is connected with a charging gun for charging external devices through a charging cable. The charging gun of the energy storage charging robot can be used to charge external new energy vehicles or other electrical devices. The charging cable can be wound and fixed by a cable reel, making the overall appearance of the energy storage charging robot neater.

[0017] In summary, the beneficial effects of the present invention are as follows: 1.

[0024] According to Figure 3As shown in the figure, a battery pack 2 is provided with a battery pack 21 inside the box body. The battery pack 21 is composed of a plurality of battery cells 211 electrically connected. A certain gap is provided between each battery cell 211 for heat dissipation. A heat conduction plate 22 is also provided at the bottom of the battery pack 21. A gap is provided between the plurality of battery cells 211 in the battery pack 21, so that the heat generated by the battery cells 211 during operation will not be too concentrated, resulting in difficult heat dissipation. The heat conduction structure design of the heat conduction plate 22 at the bottom of the battery pack 21 can better transfer the heat of the battery pack 21 to the liquid cooling plate 23 at the bottom of the heat conduction plate 22, making the heat dissipation effect better.

[0025] According to Figure 4 As shown in the figure, the heat conduction plate 22 is provided with an upper layer and a lower layer, and the upper layer and the lower layer are supported and connected by a plurality of support columns 225. The upper layer and the lower layer of the heat conduction plate 22 are supported and connected by a plurality of support columns 225, so that the heat conduction plate 22 can bear the weight of the battery pack 21 on the heat conduction plate 22. The upper layer of the heat conduction plate 22 can absorb the heat generated by the battery cells 211 in the battery pack 21 and transfer it to the lower layer of the heat conduction plate 22. After that, the lower layer of the heat conduction plate 22 will transfer the heat to the liquid cooling plate 23 and then dissipate the heat through the liquid cooling water.

[0026] According to Figure 4 As shown in the figure, the top of the upper layer of the heat conduction plate 22 is a heat conduction top cover 221, and a layer of top liquid absorption core 222 is fixedly provided at the lower part of the heat conduction top cover 221. The lower layer of the heat conduction plate 22 is successively provided with a bottom liquid absorption core 223 and a heat conduction bottom cover 224, and the bottom liquid absorption core 223 and the heat conduction bottom cover 224 are fixedly connected. The heat conduction top cover 221 and the heat conduction bottom cover 224 of the heat conduction plate 22 are both made of copper plates with excellent heat conduction performance. Using the good heat conduction performance of copper, the heat generated by the battery cells 211 of the battery pack 21 can be quickly conducted out, and the heat accumulation can be prevented from causing the temperature of the battery pack 2 to be too high.

Abundant capillary pores are formed between the copper powders, which can provide good capillary force for the cooling liquid inside the wick, enabling the coolant to flow and circulate smoothly therein, making heat transfer more efficient; the heat generated when the battery pack 21 works is absorbed by the heat conduction top cover 221 of the heat conduction plate 22. After the heat conduction top cover 221 absorbs the heat, it will transfer the heat to the top wick 222. The cooling liquid contained in the top wick 222 vaporizes into steam when heated. The steam will diffuse to the bottom wick 223 with a lower temperature at the bottom under the action of air pressure. When the steam reaches the bottom wick 223, it will condense into a liquid and transfer the heat to the heat conduction bottom cover 224 through the bottom wick 223 and then transfer it out. Finally, the heat is dissipated through the liquid-cooled water in the liquid-cooled plate 23 below the heat conduction bottom cover 224 to complete the liquid cooling and heat dissipation of the battery pack 2. The liquid condensed from the steam will finally flow back through the capillary effect to form a cycle inside the heat conduction plate 22; the rough surface of the wick is equivalent to forming more tiny capillary pores, and the radius of these capillary pores is smaller, thereby enhancing the capillary force of the cooling liquid, which can make the cooling liquid more easily flow back from the bottom wick 223 at the bottom layer to the top wick 222 at the upper layer, ensuring the circulation of the cooling liquid inside the heat conduction plate 22 and making the heat transfer and conduction of the heat conduction plate 22 more efficient.
