A battery for electric vehicle with temperature control alarm function

Abstract

The present invention relates to a battery for electric vehicles with a temperature control alarm function applied to the field of batteries. When working, a hair dryer blows air toward the interior of an assembly box, and the wind can dissipate heat for all batteries. When the temperature of the batteries on the left side of the vent rises, the wind blocking plate moves downward to close the vent, and the opening and closing plate flips to open the switch tube. At this time, the high-temperature wind on the left side of the vent is discharged outwardly through the air regulating tube and the switch tube on the left, and the exhaust fan is driven to rotate during the discharge process. After the exhaust fan rotates, the blower fan is driven to rotate through the rotating shaft, the transmission wheel, and the transmission belt. At this time, the low-temperature wind from the outside enters the interior of the assembly box through the switch tube and the air regulating tube on the right side of the vent, and dissipates heat for the batteries on the right side of the vent. Through the above-mentioned arrangement, it can be avoided that when one of the batteries has an abnormal temperature rise, the heat dissipation effect of the other batteries is affected, thereby improving the overall heat dissipation effect of the multiple batteries.

Description

Technical Field

[0001] The invention relates to a storage battery for electric vehicles with a temperature control alarm function, in particular to a storage battery for electric vehicles with a temperature control alarm function applied in the field of storage batteries. Background Art

[0002] Electric vehicle batteries generate heat when working or charging. When the temperature of the battery is too high, it will affect the service life of the battery. In severe cases, it will cause damage to the battery. In order to protect the battery, an air-cooled radiator is usually installed at the battery.

[0003] When the air-cooled radiator is working, the heat of the battery is taken away by the flow of wind. The battery is composed of multiple individual batteries. When the temperature of the battery close to the air-cooled radiator rises abnormally, the temperature of the wind blown out by the air-cooled radiator rises after passing through the battery with abnormal temperature. At this time, after the high-temperature wind flows to the position of the remaining batteries, it not only fails to dissipate heat for the battery, but also causes the temperature of the remaining batteries to rise, seriously affecting the overall heat dissipation effect of the battery. Therefore, further improvement is needed. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that when the temperature of the battery near the air-cooled radiator rises abnormally, it not only fails to dissipate heat for the remaining batteries, but also causes the temperature of the remaining batteries to rise, seriously affecting the overall heat dissipation effect of the battery.

[0006] As a further improvement of the present application, a thermal control mechanism is installed in the assembly box between the two air regulating pipes, and the thermal control mechanism includes a support plate and a pressure pipe fixedly connected to the outer wall of the assembly box, and a heating box fixedly connected to the inner wall of the assembly box.

[0007] As a further improvement of the present application, the inner wall of the pressure tube is slidably connected to a piston, the top of the piston is fixedly connected to a lifting rod, the top of the lifting rod and the top of the wind blocking plate are both fixedly connected to an intermediate tooth plate, and the side wall of the support plate is fixedly connected to a conversion gear, which meshes with the two conversion gears.

[0008] As a further improvement of the present application, a connecting pipe is provided between the top end of the heating box and the bottom end of the pressure pipe, and the heating box is located on the left side of the vent.

Through the above arrangement, it is possible to avoid affecting the heat dissipation effect of the remaining batteries when one of the batteries has an abnormal temperature rise, thereby improving the overall heat dissipation effect of multiple batteries.

[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

[0025] Figure 1-7A battery for electric vehicles with a temperature control alarm function is shown, comprising an assembly box 1, a plurality of evenly distributed lower wind shields 2 are fixedly connected to the inner wall at the bottom end of the assembly box 1, a plurality of evenly distributed upper wind shields 3 are fixedly connected to the inner wall at the top end of the assembly box 1, a plurality of lower wind shields 2 and upper wind shields 3 are alternately distributed, a plurality of batteries 4 are installed inside the assembly box 1, the plurality of batteries 4 are respectively located between the plurality of lower wind shields 2 and the upper wind shields 3, a vent 5 is set between the top of the lower wind shield 2 and the inner wall of the assembly box 1, a blower 6 and an exhaust port 7 are respectively fixedly connected to the two ends of the assembly box 1, an air regulating duct 8 is fixedly connected to the top of the assembly box 1 on both sides of the vent 5, and the air regulating duct 8 A support rod 9 is fixedly connected to the inner wall, and a rotating shaft 10 is rotatably connected to the middle part of the support rod 9. The top end of the rotating shaft 10 extends to the outside of the air regulating pipe 8 and is fixedly connected to a transmission wheel 11. A transmission belt 12 is rotatably connected between the two transmission wheels 11. The ends of the two air regulating pipes 8 close to each other are fixedly connected to switch pipes 15, and the switch pipes 15 are connected to the air regulating pipes 8. The inner wall of the switch pipe 15 is rotatably connected to a switch shaft 13, and an opening and closing plate 14 is fixedly connected to the outer wall of the switch shaft 13. One end of the switch shaft 13 extends to the outside of the switch pipe 15 and is fixedly connected to a rotating tooth 16. A slide groove 19 is fixedly connected to the top of the assembly box 1 near the vent 5, and a wind blocking plate 20 is slidably connected to the inner wall of the slide groove 19.

[0026] The hair dryer 6 blows air toward the interior of the assembly box 1. Under the action of the lower wind shield plate 2 and the upper wind shield plate 3, the wind passes through the vent 5 in an S shape inside the assembly box 1 and is discharged outward through the exhaust port 7. At this time, the wind blown by the hair dryer 6 can dissipate heat for all batteries 4.

[0027] When the temperature of the battery 4 on the left side of the vent 5 rises abnormally, the temperature of the wind will rise. At this time, when the wind flows inside the assembly box 1, it will not only fail to dissipate the heat for the battery 4, but may also cause the temperature of the remaining batteries 4 to rise abnormally due to the high temperature of the wind itself.

[0028] Through the above arrangement, when the temperature of the battery 4 on the left side of the vent 5 rises, the wind blocking plate 20 moves downward to close the vent 5, and the opening and closing plate 14 flips over to open the switch tube 15. At this time, the high-temperature wind on the left side of the vent 5 is discharged outward through the air regulating tube 8 and the switch tube 15 on the left, and the exhaust fan 17 is driven to rotate during the discharge process. After the exhaust fan 17 rotates, the blower fan 18 is driven to rotate through the rotating shaft 10, the transmission wheel 11, and the transmission belt 12. At this time, the low-temperature wind from the outside enters the interior of the assembly box 1 through the switch tube 15 and the air regulating tube 8 on the right side of the vent 5 to dissipate the heat of the battery 4 on the right side of the vent 5.

[0029] Through the above arrangement, it is possible to avoid affecting the heat dissipation effect of the remaining batteries 4 when one of the batteries 4 has an abnormal temperature rise, thereby improving the overall heat dissipation effect of the multiple batteries 4.

[0030] A temperature sensor 23 is fixedly connected to the top of the switch tube 15, and a buzzer 24 is fixedly connected to one end of the assembly box 1. The temperature sensor 23 and the buzzer 24 are electrically connected. Through the above arrangement, the temperature sensor 23 can detect the temperature of the gas discharged from the switch tube 15. When the temperature of the gas discharged from the switch tube 15 is too high, an electrical signal is sent to the buzzer 24 to make it sound an alarm, thereby reminding the rider.

[0031] A protection frame 25 is fixedly connected to the outer wall of the assembly box 1 , and the protection frame 25 covers the outer sides of the two air regulating pipes 8 .

[0032] The second implementation method:

[0033] Figure 1-3 and Figure 6-7 A battery for electric vehicles with a temperature control alarm function is shown. Different from the first embodiment, the assembly box 1 is provided with a thermal control mechanism between the two air regulating pipes 8. The thermal control mechanism includes a support plate 22 and a pressure pipe 2201 fixedly connected to the outer wall of the assembly box 1, and a heat receiving box 2205 fixedly connected to the inner wall of the assembly box 1. A piston 2207 is slidably connected to the inner wall of the pressure pipe 2201. A lifting rod 2208 is fixedly connected to the top of the piston 2207. The top of the lifting rod 2208 and the air blocking plate 2 0 are fixedly connected with an intermediate tooth plate 2203 at the top, a conversion gear 2204 is fixedly connected to the side wall of the support plate 22, the conversion gear 2204 is meshed with the two conversion gears 2204, a connecting pipe 2206 is connected between the top of the heating box 2205 and the bottom end of the pressure pipe 2201, the heating box 2205 is located on the left side of the vent 5, and the ends of the two intermediate tooth plates 2203 away from each other are fixedly connected with a gear plate 2202, and the two gear plates 2202 are respectively meshed with two rotating teeth 16.

[0034] When the temperature of the battery 4 on the left side of the vent 5 rises abnormally, the heat box 2205 is heated and the gas inside expands, pushing the piston 2207 to move upward. After the piston 2207 moves upward, it pushes the middle tooth plate 2203 on the left to move upward. After the middle tooth plate 2203 on the left moves upward, it drives the middle tooth plate 2203 on the right to move downward through the conversion gear 2204. After the middle tooth plate 2203 on the right moves downward, it pushes the air blocking plate 20 to move downward to block the vent 5. At the same time, the middle tooth plates 2203 on the left and right sides drive the opening and closing plates 14 to flip through the gear plate 2202 and the rotating gear 16 during the process of rising and falling, thereby opening the two switch tubes 15.

[0035] Through the above arrangement, when an abnormal temperature occurs at the position of the vent 5 , the high temperature generated by the battery 4 can be used to automatically block the vent 5 and open the switch tube 15 .

[0036] One end of the hair dryer 6 and the top of the switch tube 15 on the right side of the vent 5 are both fixedly connected with a filter 21 . The filter 21 can filter the air entering the assembly box 1 .

[0037] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
