Battery charging and cooling device for automobile battery swap station

Abstract

A battery charging and cooling device for a car battery swapping station, belonging to the field of automotive battery technology, addresses the problem that existing fast charging of car batteries results in high current and rapid heat generation, while also considering the need for efficient battery swapping stations. This invention utilizes a hollow tube pressure plate with a hollow connection at both ends to a cooling mechanism, allowing air to blow outwards from an air outlet on one side of the exhaust pipe. A spring provides elasticity to the positioning mechanism to prevent battery damage. The charging component is located at the top, where charging heat is first transferred to the upper part of the casing. The exhaust pipes are located on both sides of the upper part of the car battery, allowing flowing cool air to contact the high-temperature surface, carrying away heat and becoming hot air. This hot air is then forced out by the exhaust pipes, moving away from the heat source. A positioning frame is used to fix car batteries in multiple rows and columns, enabling mass movement of the batteries. A telescopic rod can move the entire car battery assembly placed on the rack. The charging component corresponds to the charging head fixed on the hollow tube pressure plate, achieving simultaneous charging of large quantities.

Description

Technical Field

[0001] This invention relates to the field of automotive battery technology, and in particular to a battery charging and cooling device for automotive battery swapping stations. Background Technology

[0002] With the increasing popularity of new energy battery vehicles, battery swapping stations are also becoming more and more common. These stations are mainly used to replace the batteries in electric vehicles. They can pre-charge batteries that may need to be swapped in the future, so that the swapping can be done directly when the vehicle arrives.

[0003] Existing car batteries typically require centralized, dense, and high-power charging at battery swapping stations. Fast charging equals high current, which in turn generates rapid heat. High temperatures cause a sharp drop in battery life, a surge in the risk of thermal runaway, and a significant increase in the probability of fire and heat spread. At the same time, battery swapping stations need to consider turnover efficiency to prevent batteries from running out of power, which would cause waiting time and affect customer experience. Centralized charging compartments are high-risk areas and must be equipped with strong heat dissipation and heat accumulation prevention measures.

[0004] To address the aforementioned problems, a battery charging and cooling device for car battery swapping stations is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a battery charging and cooling device for car swapping stations, which solves the problems in the prior art where existing car batteries are typically charged at high power in a concentrated, dense, and simultaneous manner at swapping stations. Fast charging equals high current, which leads to rapid heat generation. When the temperature is high, the battery life drops sharply, the risk of thermal runaway increases dramatically, and the probability of fire and heat spread increases significantly. At the same time, swapping stations need to consider the turnover efficiency to prevent the batteries from running out of power, which would cause waiting time and affect the customer experience. The centralized charging compartment is a high-risk area and must be equipped with strong heat dissipation and heat accumulation prevention measures.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery charging and cooling device for a car swapping station, comprising a charging pusher, a lifting mechanism, a positioning mechanism, an air-cooling mechanism, and a car battery. The upper end of the charging pusher is fixedly equipped with a lifting mechanism for pressing, and the lower end of the lifting mechanism is connected to a positioning mechanism for fixing. The output end of the charging pusher holds the car battery, and the side end of the car battery is fixedly equipped with an air-cooling mechanism. The charging pusher includes a fixedly installed telescopic rod, the output end of which is connected to a frame plate. Multiple sets of car batteries are provided, and the outer end of each car battery is surrounded by a positioning frame plate, with a charging component at the upper end. The lifting mechanism includes a vertically lifting hollow tube pressure plate, with a charging head corresponding to the charging component on the hollow tube pressure plate. One end of the hollow tube pressure plate is connected to the air-cooling mechanism. The positioning mechanism is fixed to both ends of the hollow tube pressure plate and is used to align and press the positioning frame plate. The positioning mechanism includes an elastically installed spring. The air-cooling mechanism includes an air outlet pipe connected to the hollow tube pressure plate, with an air outlet at one end.

[0007] Furthermore, two sets of guide rails are fixedly installed at the upper end of the housing.

[0008] Furthermore, beveled blocks are provided around the perimeter of the frame.

[0009] Furthermore, the lifting mechanism also includes a top frame fixedly installed at the upper end of the housing, and multiple sets of cylinder components are fixedly installed inside the top frame.

[0010] Furthermore, the lifting mechanism also includes a pressure plate positioning component that is aligned with the car battery, and the pressure plate positioning component is fixedly disposed at the lower end of the empty tube pressure plate.

[0011] Furthermore, the positioning mechanism also includes a screw connector fixedly disposed on the upper end of the spring member, the screw connector being fixed to the empty tube pressure plate screw, and a pressure rod being sleeved on the lower end of the spring member.

[0012] Furthermore, the air-cooling mechanism also includes fan boxes fixedly installed on both sides inside the top frame. Two sets of fan boxes are symmetrically arranged, and the output end of the fan box is connected to an external air duct.

[0013] Furthermore, a connecting pipe is fixedly provided on the side end of the empty pipe pressure plate.

[0014] Furthermore, the air outlet is located inside the air outlet pipe.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention provides a battery charging and cooling device for a car battery swapping station. The hollow ends of the hollow pipe pressure plate are connected to a wind-cooling mechanism, allowing air to blow outwards from the air outlet on one side of the air pipe. Two sets of air outlets and four sets of positioning mechanisms are provided on the side of each car battery. Multiple sets of positioning mechanisms are also provided on both sides of the positioning frame plate. These positioning mechanisms surround the positioning frame plate to achieve precise positioning and ensure the charging position does not shift. Springs provide elastic force to the positioning mechanism as a whole to prevent battery damage. During charging, the charging component of the car battery is positioned at the upper end, and the positioning frame plate... The car battery is connected in multiple sets. Since the charging components are located at the top, the heat from the charging heating elements is first transferred to the top of the casing. The air ducts are located on both sides of the top of the car battery. The flowing cool air can come into contact with the high-temperature surface, carrying away the heat and turning it into hot air. The hot air is forced out by the air ducts, away from the heat source, avoiding heat backflow and accumulation. This solves the problem that existing car batteries usually need to be charged in a concentrated, dense, and high-power manner at the same time in battery swapping stations. Fast charging equals high current, which equals rapid heat generation. When the temperature is high, the battery life drops sharply, the risk of thermal runaway soars, and the probability of fire and heat spread increases significantly.

[0016] 2. The present invention provides a battery charging and cooling device for a car swapping station. The positioning frame is used to fix car batteries in multiple rows and columns. The positioning frame is a device for the overall movement of existing car swapping station mechanical equipment, realizing the batch movement of car batteries. The telescopic rod can drive the car batteries placed on the frame to move as a whole, so as to align with the lifting mechanism to move to the charging position at the lower end. The charging component corresponds to the charging head fixed on the empty tube pressure plate, realizing the synchronous charging of a large number of batteries. This solves the problem of the turnover efficiency that the swapping station needs to consider, and prevents the battery of the swapping station from running out of power, causing waiting time and affecting the customer experience.

Detailed Implementation

[0019] 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.

[0020] In order to solve existing technical problems, such as Figures 1-8 As shown, the following preferred technical solutions are provided: A battery charging and cooling device for a car swapping station includes a charging pusher 1, a lifting mechanism 2, a positioning mechanism 3, an air-cooling mechanism 4, and a car battery 5. The upper end of the charging pusher 1 is fixedly equipped with the lifting mechanism 2 for pressing, and the lower end of the lifting mechanism 2 is connected to the positioning mechanism 3 for positioning and fixing. The output end of the charging pusher 1 holds the car battery 5, and the side end of the car battery 5 is fixedly equipped with the air-cooling mechanism 4. The charging pusher 1 includes a fixedly installed telescopic rod 12, and the output end of the telescopic rod 12 is connected to a frame plate 13. Multiple sets of car batteries 5 are provided. The outer end is surrounded by a positioning frame plate 52, and the upper end is provided with a charging component 51. The lifting mechanism 2 includes a vertically lifting empty tube pressure plate 23. A charging head 25 is provided on the empty tube pressure plate 23 corresponding to the charging component 51. One end of the empty tube pressure plate 23 is connected to a wind-cooling mechanism 4. The positioning mechanism 3 is fixed at both ends of the empty tube pressure plate 23. The positioning mechanism 3 is used to align and press the positioning frame plate 52. The positioning mechanism 3 includes a spring 32 that is elastically provided. The wind-cooling mechanism 4 includes an air outlet pipe 44 that is connected to the empty tube pressure plate 23. One end of the air outlet pipe 44 is provided with an air blowing port 441.

[0021] Specifically, the positioning frame plate 52 is used to fix multiple rows and columns of car batteries 5. The positioning frame plate 52 is a device for the overall movement of existing battery swapping station mechanical equipment, realizing the batch movement of car batteries 5. The telescopic rod 12 can drive the car batteries 5 placed on the frame plate 13 to move as a whole, so as to align with the lifting mechanism 2 to move to the lower charging position. The hollow ends of the hollow tube pressure plate 23 are hollowly connected to the air cooling mechanism 4, so that the air outlet 441 opened on one side of the air outlet 44 can blow air outward. Two sets of air outlet 44 are set on the side of each car battery 5. Four sets of positioning mechanisms 3 are also set on both sides of the positioning frame plate 52. The positioning mechanisms 3 are set around the positioning frame plate 52 to achieve precise positioning and ensure that the charging position does not shift. The spring 32 provides elastic force for the positioning mechanism 3 as a whole to prevent damage to the battery. When this battery swapping station charging device is charging, the charging component 51 of the car battery 5 is set in At the upper end, the positioning frame plate 52 is connected to the car battery 5 in multiple sets. Since the charging component 51 is located at the upper end, the heat of the charging heating element is first transferred to the upper end of the shell. The air outlet pipe 44 is located on both sides of the upper end of the car battery 5. The flowing cold air can come into contact with the high temperature surface, take away the heat and become hot air. The hot air is blown out by the air outlet pipe 44 and forced away from the heat source to avoid heat backflow and accumulation. This solves the problem that existing car batteries usually need to be charged in a concentrated, dense and high-power manner at the same time in the battery swapping station. Fast charging is equivalent to high current, which is equivalent to rapid heat generation. When the temperature is high, the battery life drops sharply, the risk of thermal runaway soars, and the probability of fire and heat spread increases greatly. The charging component 51 corresponds to the charging head 25 fixed on the empty pipe pressure plate 23 to realize the synchronous charging of a large number of batteries. This solves the problem that the battery swapping station needs to consider the turnover efficiency and prevents the battery swapping station from running out of power, which causes waiting time and affects the customer experience.

[0022] Two sets of guide rails 111 are fixedly installed at the upper end of the housing 11. The two sets of guide rails 111 provide guidance for the movement of the frame plate 13. Angled blocks 131 are provided around the frame plate 13. One side of the angled block 131 is set as an angle to provide angled positioning for the positioning frame plate 52. A total of eight sets of angled blocks 131 are provided, which are evenly distributed on the outer ends of the four sides of the positioning frame plate 52 to realize the movement and positioning of the car battery 5.

[0023] The lifting mechanism 2 further includes a top frame 21 fixedly arranged at the upper end of the box body 11. Inside the top frame 21, multiple cylinder components 22 are fixedly arranged. The top frame 21 is used to support and fix the cylinder components 22. The cylinder components 22 are evenly distributed to achieve uniform extrusion during charging. The multiple cylinder components 22 are mechanically forced to be synchronized. The output ends of the multiple cylinder components 22 are fixedly connected with an air tube pressing plate 23. The air tube pressing plate 23 is a steel plate with sufficient rigidity. The two ends are hollow and connected to the air outlet pipe 44. Since the air tube pressing plate 23 has sufficient rigidity, no matter how small the differences in thrust and speed of the cylinder components 22 are, they will be forced to be synchronized by the rigid plate of the air tube pressing plate 23. The lifting mechanism 2 further includes a pressing plate positioning part 24 arranged to align with the vehicle battery 5. The pressing plate positioning part 24 is fixedly arranged at the lower end of the air tube pressing plate 23. The pressing plate positioning part 24 reserves space for the air-cooling of the air-cooling mechanism 4. The pressing plate positioning part 24 is arranged in a "king" shape to ensure that the pressing is in place and guarantee the stability of the charging connection.

[0024] The positioning mechanism 3 further includes a screw connecting part 31 fixedly arranged at the upper end of the spring part 32. The screw connecting part 31 is fixedly connected to the air tube pressing plate 23 by screws. The lower end of the spring part 32 is sleeved with a pressing rod 33. The spring part 32 provides elastic force for the pressing rod 33. The screw connecting part 31 realizes the connection between the spring part 32 and the air tube pressing plate 23. The elastic force of the spring part 32 provides a certain buffer force for the positioning mechanism 3 to press and position the positioning frame plate 52.

[0025] The air-cooling mechanism 4 further includes blower boxes 41 fixedly arranged on both sides inside the top frame 21. There are two groups of blower boxes 41 arranged symmetrically. The output ends of the blower boxes 41 are connected with external air ducts 42. The blower boxes 41 serve as an energy storage and buffer center, responsible for delivering air with low temperature, dryness, and stable pressure to the external air ducts 42 as required. Inside the blower boxes 41, there is dry and cold air connected from a cold dryer. A pressure regulating valve is arranged at the outlet of the blower boxes 41. Through the pressure regulating valve, the high-pressure gas can be reduced to the working pressure to achieve stable cold air flow delivery. A connecting pipe 43 is fixedly arranged at the side end of the air tube pressing plate 23. The connecting pipe 43 is connected to the external air duct 42 to realize air delivery. An air outlet 441 is opened inside the air outlet pipe 44. The air outlet 441 is opened inside and can blow air towards the upper end of the vehicle battery 5 to increase the air flow velocity at the charging and heat dissipation end of the vehicle battery 5.
