Description

Technical Field

[0001] This invention relates to the field of power vehicle technology, specifically a modular emergency mobile energy storage vehicle. Background Technology

[0002] Emergency mobile energy storage vehicles are mobile energy storage and power supply equipment designed for peak electricity demand replenishment and emergency power outage scenarios. They use modular battery packs as the core energy storage carrier and achieve continuous and stable power output through the charging and discharging cycles of the battery packs. They can quickly reach various power demand sites to complete deployment, promptly make up for power grid gaps, and ensure the normal operation of production and daily life.

[0003] For example, patent CN218586904U discloses a portable power bank cart, including omnidirectional rollers, a base frame, a power bank frame, a servo motor, movable blocks, and movable plates. The power bank frame is fixedly installed at the top center of the base frame with bolts. A fixed box is fixedly installed at the top center of the outer side of the base frame with bolts. Bearing seats are fixedly installed at the top centers of both ends of the inner top of the base frame with bolts, and a rotating rod is fixedly installed between the movable parts of the bearing seats. Movable blocks are movably connected to the two ends of the rotating rod inside the base frame through positive and negative threads. The omnidirectional rollers enable the movement of the power bank frame. When fixed, the servo motor reverses to cause the movable plate to drive the omnidirectional rollers into the movable holes. The support feet achieve stable fixation of the power bank frame, preventing the cart from falling off when connecting to power, thus ensuring strong safety performance.

[0004] For example, patent CN219394470U discloses a portable DC mobile power supply vehicle, including a carriage, a rectifier module, and a battery module. The carriage is divided into two layers by a transverse partition, with the rectifier module located on the upper layer and the battery module on the lower layer. The outer surface of the carriage is equipped with an AC power input module and a DC power output module. The input and output ends of the rectifier module are electrically connected to the AC power input module and the DC power output module, respectively. The battery module is connected in parallel with the rectifier module. By setting up the rectifier module and the battery module and connecting them in parallel, the DC mobile power supply vehicle can not only be directly connected to an AC power source to convert it into DC power, but also store electrical energy through the battery module, which is convenient for providing power when there is no external power source, thus improving the flexibility of use.

[0005] For example, patent CN219833812U discloses a mobile power bank vehicle. This vehicle includes a body, a walking module, and a power module. The walking module is located below the body, and the body contains a mounting frame and multiple slide rails. Each slide rail is mounted on the mounting frame, and the power module is mounted on the mounting frame via the slide rails. The power module includes multiple battery packs, each with a first connection end. The mounting frame contains multiple second connection ends. The walking module can make minor adjustments to the mobile power bank vehicle. Because each battery pack is slidably connected to each slide rail, the first connection end of each battery pack can abut against the respective second connection ends of the mounting frame, thereby connecting each battery pack. The first connection end of the battery pack is electrically connected to each of the second connection ends of the mounting bracket. Therefore, by pushing the battery pack, the power module can be installed and electrically connected to the vehicle body at the same time, which is convenient. However, in some existing vehicles, the interior space is limited, making it inconvenient for staff to enter the vehicle during the battery pack installation and removal process. It is also inconvenient to operate the battery pack and connect it to the vehicle's charging and discharging system. In addition, after the battery pack is connected and installed, the connection between it and the vehicle's charging and discharging system is prone to loosening due to the vibration and shaking caused by the vehicle driving or parking. This can lead to poor contact, increased charging and discharging contact resistance, and affect the stability and efficiency of power transmission.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing emergency mobile energy storage vehicles. Summary of the Invention

[0007] The purpose of this invention is to provide a modular emergency mobile energy storage vehicle to solve the problems mentioned in the background art, such as limited interior space in some existing vehicles, making it inconvenient for workers to enter the vehicle interior during battery pack installation and removal, and making it difficult to connect the battery pack to the vehicle's charging and discharging system. In addition, after the battery pack is connected and installed, the connection between the battery pack and the vehicle's charging and discharging system is prone to loosening due to vibrations and shaking from vehicle movement or parking, leading to poor contact, increased charging and discharging contact resistance, and affecting the stability and efficiency of power transmission.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a modular emergency mobile energy storage vehicle, comprising a vehicle body for providing emergency power, a side compartment mounted on the vehicle body, and multiple protective doors rotatably mounted on the side compartment; a frame fixedly mounted inside the side compartment, a mounting plate fixedly mounted centrally on the frame, and multiple pin interfaces fixedly mounted on the mounting plate; a guide rail fixedly mounted on the frame, a slide block slidably mounted on the guide rail, and a mounting seat fixedly mounted on the slide block; two sets of mounting seats are symmetrically arranged about the pin interfaces, and a connecting column is fixed between the upper and lower sets of mounting seats; a mounting groove is provided on the mounting seat, and a battery pack is fitted inside the mounting groove; a plug interface for docking with the pin interfaces is installed on the back of the battery pack; a correction mechanism for adjusting the charging docking position of the battery pack is provided on the mounting seat, and a locking-disconnecting composite mechanism for assisting in the stable insertion and removal of the battery pack is provided on the mounting seat.

[0009] Preferably, a BMS module for managing the safety status of multiple battery packs is fixedly installed inside the vehicle compartment, and a PCS module for regulating the power conversion and charging / discharging of multiple battery packs is also fixedly installed inside the vehicle compartment.

[0010] Preferably, the correction mechanism includes a guide slide rod vertically fixed on the connecting column, a movable bracket slidably mounted on the guide slide rod, and a pressure column fixed on the side of the movable bracket near the battery pack. The pressure column moves along the direction of the guide slide rod and contacts and presses against the side of the battery pack.

[0011] Preferably, the frame is fixedly installed with a directional slide rail by a support, and the movable bracket is slidably connected in the directional slide rail; the directional slide rail is provided with a rear straight groove, an oblique groove and a front straight groove, the rear straight groove is located on the side near the pin interface, and the oblique groove is connected through the rear straight groove and the front straight groove.

[0012] Preferably, the locking-disconnecting composite mechanism includes a locking pin rotatably mounted on a pressure pin, the locking pin rotatably pressing against the front surface of the battery pack, and the side of the battery pack near the locking pin having an angled edge; a rubber ring is fitted around the locking pin, and a handle is fixed to the locking pin along the rotation axis.

[0013] Preferably, a C-shaped frame is slidably installed between the upper and lower mounting seats. Hollow slip rings are fixed at both the upper and lower parts of the C-shaped frame, and a rod is slidably inserted through the hollow slip rings longitudinally. A sliding groove is opened laterally on the mounting seat, and the hollow slip ring is slidably installed inside the sliding groove. A crossbar is fixedly installed on the frame, and a positioning hole corresponding to the position of the rod is opened on the crossbar. The rod moves upward and engages with the positioning hole.

[0014] Preferably, a rotating rod is rotatably connected to the side of the pressure post away from the locking post. The rotating rod is fixedly connected to the locking post, and a protruding rod is fixedly installed on the rotating rod. A driven rod is rotatably connected to the protruding rod, and the other end of the driven rod is rotatably connected to the insertion rod.

[0015] Preferably, a speed limiter for limiting the insertion and removal speed of the battery pack is installed on the side of the C-shaped frame near the mounting plate, and two sets of speed limiters are arranged longitudinally on the C-shaped frame.

[0016] Preferably, the speed limiter includes a telescopic rod fixedly connected to the C-shaped frame, a speed limit sleeve fixed to the telescopic end of the telescopic rod, and a speed limit spring elastically connected inside the speed limit sleeve to the surface of the C-shaped frame.

[0017] Preferably, the locking-disconnecting composite mechanism further includes a transmission disc fixed to the outside of the speed limiting sleeve near the rotating rod; a push block is fixed to one end of the rotating rod extending out of the C-shaped frame, and a power disc is fixed to the side of the push block near the transmission disc.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the modular emergency mobile energy storage vehicle realizes charging and discharging operations in emergency situations through multiple battery packs in the vehicle compartment, provides emergency power, ensures power demand, and the battery packs are connected to the pin interfaces in the vehicle compartment through plug interfaces, which can be quickly assembled and disassembled in the vehicle compartment to meet the needs of emergency power supply.

[0019] The mounting base is equipped with a correction mechanism to adjust the charging docking position of the battery pack. After the battery pack is installed on the mounting base, it is moved into the vehicle compartment by a slide block and guide rail. At this time, the moving bracket moves from the front straight groove to the rear straight groove in the adjusting slide. Guided by the inclined groove, the moving bracket generates lateral displacement, which drives the pressure column to move closer to the battery pack, correcting the position of the battery pack on the mounting base and keeping the battery pack centered and stable on the mounting base so that the socket interface on the battery pack can be quickly docked with the pin interface in the vehicle compartment. The installation process does not require personnel to enter the vehicle compartment, making it convenient and highly accurate.

[0020] The mounting base is equipped with a locking-disconnecting composite mechanism to assist in the stable insertion and removal of the battery pack. After the battery pack is connected to the pin interface, the locking pin rotates and locks itself to the front of the battery pack. The rubber ring on the locking pin deforms elastically and presses against the surface of the battery pack, pushing the battery pack to move closer to the pin interface. This keeps the connection between the socket interface and the pin interface stable. Furthermore, when the battery pack is pushed to connect with the pin interface, the speed limiter reduces its movement and connection speed, preventing the pin interface and socket interface from colliding rapidly and causing local structural deformation.

[0021] The battery pack is clamped and limited by the pressure columns on both sides, and the front surface of the battery pack is clamped and limited by the locking columns. Under the multiple limiting effects, the battery pack can be stably installed in the vehicle compartment for power supply and use, reducing the impact of vehicle compartment shaking on its connection to power supply or charging.

[0022] The locking-disconnecting composite mechanism also includes a push block that is rotatably mounted at the end of the mounting base. During the disassembly of the battery pack, as the locking pin rotates away from the surface of the battery pack, it can drive the push block to rotate synchronously. The push block rotates and approaches the transmission disc. Under the squeezing action of the power disc and the transmission disc, it can push and adjust the distance between the speed limiting sleeve and the C-shaped frame, thereby providing power for the battery pack to move away from the pin interface. The mechanical action assists in the movement and disassembly of the battery pack, making the operation convenient. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figure 1 - Figure 7 The present invention provides the following technical solution: a modular emergency mobile energy storage vehicle, comprising a vehicle body 1 for providing emergency power, a side compartment 2 mounted on the vehicle body 1, and multiple protective doors 3 rotatably mounted on the compartment 2, a frame 4 fixedly mounted inside the compartment 2, a mounting plate 5 centrally fixed on the frame 4, and multiple pin interfaces 6 fixed on the mounting plate 5; a guide rail 7 fixedly mounted on the frame 4, a slide seat 8 slidably mounted on the guide rail 7, and a mounting base 9 fixedly mounted on the slide seat 8, two sets of mounting bases 9 symmetrically arranged about the pin interfaces 6, and a connecting column 15 fixed between the upper and lower sets of mounting bases 9, a mounting groove 10 opened on the mounting base 9, a battery pack 11 fitted inside the mounting groove 10, and a plug interface 12 for docking with the pin interfaces 6 mounted on the back of the battery pack 11; a correction mechanism for adjusting the charging docking position of the battery pack 11 is provided on the mounting base 9, and a locking-disconnecting composite mechanism for assisting in the stable insertion and removal of the battery pack 11 is provided on the mounting base 9. The interior of the carriage 2 is equipped with a BMS module 14 that manages the safety status of multiple battery packs 11. The interior of the carriage 2 is also equipped with a PCS module 13 that regulates the power conversion and charging / discharging of multiple battery packs 11.

[0041] Please see Figure 5 - Figure 10The correction mechanism includes a guide slide rod 16 vertically fixed to the connecting column 15. A movable bracket 17 is slidably mounted on the guide slide rod 16. A pressure column 18 is fixed on the side of the movable bracket 17 near the battery pack 11. The pressure column 18 moves along the direction of the guide slide rod 16 and contacts and presses against the side of the battery pack 11. An adjusting slide rail 172 is fixedly mounted on the frame 4 via a support 171. The movable bracket 17 is slidably connected in the adjusting slide rail 172. The adjusting slide rail 172 has a rear straight groove 1721, an oblique groove 1722, and a front straight groove 1723. The rear straight groove 1721 is located on the side near the pin interface 6. The oblique groove 1722 is connected between the rear straight groove 1721 and the front straight groove 1723.

[0042] Multiple battery packs 11 are installed in the carriage 2. The socket interface 12 on the battery pack 11 is connected to the pin interface 6 in the carriage 2. The PCS module 13 collects the voltage, current, temperature of each cell in each battery pack 11 in real time, as well as the remaining power, health status, and charge / discharge cycle count of the battery pack 11. This allows for accurate monitoring of the real-time working status of the battery pack 11 and provides data for adjusting the charging and discharging strategy. The BMS module 14 realizes the conversion of electrical energy form and bidirectional energy scheduling, allowing the electrical energy of the battery pack 11 to adapt to the load and grid demand, while ensuring the stability and quality of power transmission. During discharge, the DC power output of the battery pack 11 is converted into AC power that meets the mains power standard to power various emergency AC loads. During charging, the AC power from the grid is converted into DC power that is compatible with the battery pack 11, realizing constant voltage and constant current charging of the battery pack 11 and meeting the charging system requirements of the battery pack 11.

[0043] When installing the battery pack 11 into the carriage 2, rotate and open the protective door 3. Pull the mounting base 9 outwards along the guide rail 7 via the sliding block 8, allowing workers to install the battery pack 11 outside the carriage 2. The battery pack 11 is fitted into the mounting base 9 via the mounting groove 10. The movable bracket 17 on the mounting base 9 is slidably positioned in the directional slide rail 172. As the mounting base 9 moves into the carriage 2, the movable bracket 17 moves sequentially from the front straight groove 1723 of the directional slide rail 172 to the inclined groove 1722 and then to the rear straight groove 1721. The movable bracket 17 undergoes a change in position within the inclined groove 1722. Lateral displacement causes the pressure column 18 to move laterally, pressing it against the outside of the battery pack 11 and pushing it to be centered on the mounting base 9, correcting its installation position. The pressure column 18 presses firmly on the left and right sides of the battery pack 11, keeping it stably mounted on the mounting base 9. When the mounting base 9 is completely moved into the frame 4, the insertion interface 12 on the back of the battery pack 11 mates with the pin interface 6 on the surface of the mounting plate 5, enabling the battery pack 11 to be quickly and accurately connected without the operator entering the carriage 2.

[0044] Example 2: Please refer to Figure 7 - Figure 14 Based on Embodiment 1, a locking-disconnecting composite mechanism is also disclosed, the specific structure of which is as follows: The locking-disconnecting composite mechanism includes a locking pin 19 rotatably mounted on the pressure pin 18, the locking pin 19 rotatably pressing against the front surface of the battery pack 11, and the side of the battery pack 11 near the locking pin 19 having an angled edge; a rubber ring 191 is sleeved on the outside of the locking pin 19, and a handle 192 is fixed to the locking pin 19 along the rotation axis. A C-shaped frame 20 is slidably mounted between the upper and lower mounting seats 9, and hollow slip rings 21 are fixed above and below the C-shaped frame 20, with a rod 23 slidingly penetrating through the hollow slip ring 21 longitudinally; a sliding groove 22 is opened laterally on the mounting seat 9, and the hollow slip ring 21 is slidably mounted inside the sliding groove 22; a crossbar 24 is fixedly mounted on the frame 4, and a positioning hole 25 corresponding to the position of the rod 23 is opened on the crossbar 24, and the rod 23 moves upward and engages with the positioning hole 25. A rotating rod 26 is rotatably connected to the side of the pressure post 18 away from the locking post 19. The rotating rod 26 is fixedly connected to the locking post 19, and a protruding rod 27 is fixedly installed on the rotating rod 26. A driven rod 28 is rotatably connected to the protruding rod 27, and the other end of the driven rod 28 is rotatably connected to the insertion rod 23.

[0045] Please see Figure 11 - Figure 14 A speed limiter 29, which limits the insertion and removal speed of the battery pack 11, is installed on the side of the C-shaped frame 20 near the mounting plate 5. Two sets of speed limiters 29 are longitudinally arranged on the C-shaped frame 20. The speed limiter 29 includes a telescopic rod 291 fixedly connected to the C-shaped frame 20. A speed limiting sleeve 292 is fixed to the telescopic end of the telescopic rod 291. A speed limiting spring 293 is elastically connected to the surface of the C-shaped frame 20 inside the speed limiting sleeve 292. The locking-disconnecting compound mechanism also includes a transmission disc 294 fixed to the outside of the speed limiting sleeve 292 near the rotating rod 26. A push block 30 is fixed to the end of the rotating rod 26 extending out of the C-shaped frame 20. A power disc 301 is fixed to the side of the push block 30 near the transmission disc 294.

[0046] After the battery pack 11 is inserted, the handle 192 drives the locking pin 19 to rotate. The locking pin 19 rotates and approaches the battery pack 11, making contact with the beveled surface of the corner of the battery pack 11. This pushes the battery pack 11 to move closer to the pin interface 6, keeping the socket interface 12 and the pin interface 6 in stable contact. At the same time, the rubber ring 191 outside the locking pin 19 undergoes elastic deformation, pressing between the locking pin 19 and the battery pack 11, further limiting the installation position of the battery pack 11, ensuring that the battery pack 11 is fully connected, and also improving the stability of the battery pack 11 installed on the mounting base 9.

[0047] During the process of pushing the battery pack 11 for installation, the speed limiting sleeve 292 first contacts the surface of the mounting plate 5. As the battery pack 11 is pushed, the speed limiting spring 293 connected between the speed limiting sleeve 292 and the C-shaped bracket 20 undergoes elastic deformation. Under the elastic buffering effect, the battery pack 11 is prevented from moving quickly close to the pin interface 6, and the socket interface 12 and the pin interface 6 are slowly and stably connected.

[0048] During the rotation of the locking pin 19, the rotating rod 26 drives the protruding rod 27 to rotate synchronously. When the protruding rod 27 rotates, the two ends of the driven rod 28 connected between the protruding rod 27 and the insertion rod 23 rotate. The rotating driven rod 28 pushes the insertion rod 23 to move upward, so that the insertion rod 23 moves into the interior of the positioning hole 25. It can limit the position of the slide 8 on the guide rail 7 at this time, and keep the battery pack 11 fully and stably installed inside the carriage 2.

[0049] When disassembling the battery pack 11, due to the limited operating space inside the compartment 2, it is inconvenient for staff to pull the battery pack 11 outwards. At this time, the locking pin 19 is rotated in the opposite direction by the handle 192, causing the locking pin 19 to rotate away from the battery pack 11. Under the transmission of the reverse rotation of the protruding rod 27, the insertion rod 23 moves away from the positioning hole 25. At this time, the handle 192 is rotated in the opposite direction. The handle 192 drives the push block 30 to rotate through the rotating rod 26. The power disc 301 on the push block 30 moves closer to the transmission disc 294. The arc surface of disc 301 contacts and presses against the arc surface of transmission disc 294. Under mechanical pressure transmission, the C-shaped frame 20 and the speed limiting sleeve 292 can move and separate. The speed limiting sleeve 292 is pressed against the surface of mounting plate 5. Under the reverse force, the C-shaped frame 20 generates a force to move out of the carriage 2, which can drive the mounting base 9 and battery pack 11 to move and extend out of the carriage 2. Thus, the plug interface 12 and pin interface 6 are separated by mechanical force. There is no need to manually pull out the battery pack 11, making the operation more convenient and safer.
