Description

Technical Field

[0002] A battery is a device that can convert chemical energy into electrical energy and release electrical energy when needed. It is mainly composed of a positive electrode, a negative electrode, a shell, etc. The battery will generate heat during operation. If the battery generates heat seriously, it will cause damage to the battery. If the battery generates heat further, it may endanger life safety or even cause serious consequences such as fire. Batteries in the prior art are usually unable to detect the heat generated by the battery during use, and are unable to dissipate heat by themselves, which may cause danger. It is necessary to perform self-inspection on the battery during use, and take different heat dissipation measures according to different heating conditions to ensure the safety of the battery during use.

[0004] Furthermore, the battery device includes a connecting ear fixedly installed on the outer shell, a box cover fixedly installed on the outer shell, an alarm is provided on the box cover, an air push box is fixedly installed on the box cover, the air push box is in close contact with the battery, a one-way valve is provided on the box cover, a lifting column is slidably installed on the air push box, a lifting frame is fixedly installed on the lifting column, a top column is fixedly installed on the lifting frame, an inner push plate is fixedly installed on the lifting column, the inner push plate slides in the air push box, an inner cavity between the inner push plate and the air push box is filled with gas that expands due to heat, the one-way valve is connected to the inner cavity, and a sensor sheet is fixedly installed on the air push box.

[0005] Furthermore, a fan mechanism is provided in the shell, and the fan mechanism includes a long rotating shaft rotatably mounted on the connecting rotating ear, a transverse transmission wheel is fixedly mounted on the long rotating shaft, four fans are fixedly mounted on the inner walls of the shell on both sides of the battery, a blade wheel is fixedly mounted on the blade shaft of the fan, a transverse transmission belt is wound around the blade wheel and the transverse transmission wheel on the fan above near the terminal, a motor frame is fixedly mounted on the shell, a motor is fixedly mounted on the motor frame, a motor is fixedly mounted on the motor shaft of the motor, and a motor wheel is fixedly mounted on the motor shaft of the motor, and a blade transmission belt is wound around the motor wheel and the four blade wheels.

[0006] Furthermore, a power supply mechanism is provided on the motor frame, and the power supply mechanism includes an insulating sleeve fixedly installed on the motor frame, an electrode plate and a docking electrode plate are fixedly installed in the insulating sleeve, a wire taking-in is fixedly installed on the electrode plate, the wire taking-in is fixedly installed on the terminal, a motor wire is fixedly installed on the docking electrode plate, the motor wire is connected to the motor, and the insulating sleeve is made of insulating material.

[0007] Furthermore, the lifting frame is provided with a connection mechanism, and the connection mechanism includes a plastic block fixedly installed on the lifting frame, the plastic block is an insulating material, an outer slide cylinder is slidably installed on the plastic block, an inner contact piece is fixedly installed on the outer slide cylinder, an inner spring is arranged between the inner contact piece and the plastic block, an inner slide column is slidably installed in the outer slide cylinder, an outer contact piece is fixedly installed on the inner slide column, an outer spring is arranged between the outer contact piece and the plastic block, and slopes are arranged on the outer contact piece and the inner contact piece.

[0008] When the battery is working, it will generate heat, and the gas in the air push box will expand due to the heat, which will drive the inner push plate and the lifting column to rise. When the lifting column rises, it will drive the lifting frame to rise, thereby driving the top column and the plastic block to rise. When the lifting frame rises a certain distance, the outer contact piece and the inner contact piece enter between the electrode plate and the docking electrode plate, and the outer spring and the inner spring make the outer contact piece and the electrode plate in close contact, and the inner contact piece and the docking electrode plate in close contact. The current passes through the terminal, the wire, the electrode plate, the outer contact piece, the inner contact piece, the docking electrode plate and the motor wire and is connected to the motor. The motor starts to rotate and drives the motor wheel to rotate, thereby driving the fan wheel to rotate through the fan blade drive belt, thereby driving the fan blades to rotate, blowing air to cool the battery, and driving the horizontal drive wheel and the long shaft to rotate through the horizontal drive belt, thereby driving the fan on the other side of the battery to rotate synchronously. As the lifting frame continues to rise, the outer contact piece and the inner contact piece are always located between the electrode plate and the docking electrode plate, and the fan remains in working condition.

[0009] When the battery is not working and is at room temperature, if the amount of heated expansion gas in the air push box is insufficient, the inner push plate and the lifting column will descend, thereby driving the lifting frame to descend. When the lifting frame contacts the sensor sheet, the alarm will sound to prompt that there is insufficient heated expansion gas in the air push box. At this time, it is connected to the one-way valve through an external air pipe, and the one-way valve opens to replenish the heated expansion gas into the air push box.

[0010] Furthermore, the water cooling device includes a water inlet pipe fixedly mounted on a water cooling box, two switch shells are fixedly mounted on the water cooling box, an inlet end of a cooling pipe is fixedly mounted on the switch shell, the cooling pipes are distributed on both sides of the battery, and an outlet end of the cooling pipe is connected to another switch shell.

[0011] Furthermore, an opening mechanism is provided on the outer shell, and the opening mechanism includes a single-leaf rotating block rotatably mounted on the outer shell, a torsion spring is provided between the single-leaf rotating block and the outer shell, an inner rotating block is rotatably mounted in the switch shell, a through hole is provided on the inner rotating block, the inner rotating blocks of the two switch shells are fixedly connected by a long axis, a rotating wheel is fixedly mounted on the inner rotating block, and an opening transmission belt is wrapped around the rotating wheel and the single-leaf rotating block.

[0012] As the heated and expanded gas in the air push box continues to expand, it drives the inner push plate and the lifting frame to continue to rise. At this time, relying solely on the fan can no longer effectively dissipate heat. The rise of the lifting frame will drive the single-leaf rotating block to rotate, and the torsion spring will be twisted, thereby turning on the transmission belt to drive the rotating wheel, the inner rotating block and the long shaft to rotate, thereby realizing the rotation of the two cooling pipes, so that the through hole of the inner rotating block is connected to the cooling pipe, and the built-in water pump in the water cooling box draws cooling water into the cooling pipe, and the battery is cooled through the cooling pipe. When there is insufficient water in the water cooling box, water is replenished through the water inlet pipe.

[0013] Furthermore, the forced cutting device includes a fixed inner column fixedly mounted on the fixed block, a movable block is slidably mounted on the fixed inner column, an upper push plate is fixedly mounted on the movable block, a magnet is fixedly mounted on the fixed block, a magnetic sheet is fixedly mounted on the lifting frame, a tension spring is arranged between the movable block and the fixed block, the external terminal is inserted into the movable block, the movable block and the external terminal form an interference fit, and the external terminal is tightly attached to and connected with the terminal.

[0014] After the water cooling device is started, if the inner push plate and the lifting column continue to rise, the lifting frame will continue to rise and drive the top column to rise. At this time, water cooling and blowing can no longer achieve the cooling effect, and the external terminal posts need to be cut off from the terminal posts. When the top column rises and the magnetic sheet reaches a certain range of the magnet, the magnetic sheet will be adsorbed by the magnet, and the magnetic sheet will drive the lifting frame and the top column to rise. The top column will lift the upper push plate and the movable block, and the movable block will slide upward along the fixed inner column. The tension spring is stretched, and the movable block rises and drives the external terminal posts to rise, and the external terminal posts are separated from the terminal posts. At this time, the battery stops supplying power to the outside, and the alarm starts to alarm. The magnet continues to adsorb the magnetic sheet, and manual inspection is required. Then, the magnetic sheet and the magnet are manually separated to reset the lifting frame.

[0015] Compared with the prior art, the present invention has the following advantages: (1) The gas pusher box of the battery device provided in the present invention is provided with heat-expanding gas to detect the heating condition of the battery. When the battery is slightly heated, a fan mechanism is used to dissipate heat. When moderate to severe heating occurs, a water cooling device is used to dissipate heat. When particularly severe heating occurs, the terminal and the external terminal are disconnected, and the degree of automation is high. (2) After the heat-expanding gas provided in the present invention is heated and expanded, when the external contact sheet and the internal contact sheet enter between the electrode plate and the docking electrode plate, the fan mechanism starts to work. After the terminal and the external terminal are disconnected, the fan device stops working. When the water cooling device is started, the fan device keeps working, and double heat dissipation is performed, and the heat dissipation effect is good. (3) When the amount of heat-expanding gas provided in the present invention is insufficient, an alarm will be automatically sounded. When the terminal and the external terminal are disconnected, an alarm will also be automatically sounded, so as to remind the user in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figure 3-Figure 7 As shown, a power supply mechanism is provided on the motor frame 111, and the power supply mechanism includes an insulating sleeve 130 fixedly mounted on the motor frame 111, an electrode plate 131 and a docking electrode plate 132 are fixedly mounted in the insulating sleeve 130, a take-up wire 121 is fixedly mounted on the electrode plate 131, the take-up wire 121 is fixedly mounted to the terminal 102, a motor wire 122 is fixedly mounted on the docking electrode plate 132, the motor wire 122 is connected to the motor 112, and the insulating sleeve 130 is an insulating material.

[0034] like Figure 3-Figure 7 As shown, a connection mechanism is provided on the lifting frame 117, and the connection mechanism includes a plastic block 123 fixedly installed on the lifting frame 117, the plastic block 123 is an insulating material, an outer slide cylinder 128 is slidably installed on the plastic block 123, an inner contact piece 127 is fixedly installed on the outer slide cylinder 128, an inner spring 129 is provided between the inner contact piece 127 and the plastic block 123, an inner slide column 125 is slidably installed in the outer slide cylinder 128, an outer contact piece 124 is fixedly installed on the inner slide column 125, an outer spring 126 is provided between the outer contact piece 124 and the plastic block 123, and slopes are provided on the outer contact piece 124 and the inner contact piece 127.

[0035] The battery 101 generates heat when working, and the gas in the air push box 105 expands due to the heat, which drives the inner push plate 120 and the lifting column 118 to rise. When the lifting column 118 rises, it drives the lifting frame 117 to rise, thereby driving the top column 116 and the plastic block 123 to rise. When the lifting frame 117 rises a certain distance, the outer contact piece 124 and the inner contact piece 127 enter between the electrode plate 131 and the docking electrode plate 132. The outer spring 126 and the inner spring 129 make the outer contact piece 124 and the electrode plate 131 in close contact, and the inner contact piece 127 and the docking electrode plate 132 in close contact. The current passes through the terminal 102, the wire 121, the electrode plate 131, the outer contact piece 124, and the inner contact piece 127. The contact piece 124, the inner contact piece 127, the docking electrode plate 132 and the motor wire 122 are connected to the motor 112, and the motor 112 starts to rotate, driving the motor wheel 113 to rotate, thereby driving the fan wheel 108 to rotate through the fan drive belt 109, thereby driving the blades of the fan 107 to rotate, blowing air to cool the battery 101, and driving the horizontal drive wheel 115 and the long rotating shaft 104 to rotate through the horizontal drive belt 114, thereby driving the fan 107 on the other side of the battery 101 to rotate synchronously, and as the lifting frame 117 continues to rise, the outer contact piece 124 and the inner contact piece 127 are always located in the electrode plate 131 and the docking electrode plate 132, and the fan 107 remains in a working state.

[0036] When the battery 101 is not working and is at room temperature, if the amount of heat-expanded gas in the air push box 105 is insufficient, the inner push plate 120 and the lifting column 118 will descend, thereby driving the lifting frame 117 to descend. When the lifting frame 117 contacts the sensor sheet 110, the alarm 133 alarms to prompt that the heat-expanded gas in the air push box 105 is insufficient. At this time, it is connected to the one-way valve 106 through the external air pipe, and the one-way valve 106 is opened to replenish the heat-expanded gas in the air push box 105.

[0037] like Figure 8-Figure 10 As shown, the water cooling device includes a water inlet pipe 202 fixedly mounted on a water cooling box 201, two switch shells 203 are fixedly mounted on the water cooling box 201, the inlet end of a cooling pipe 204 is fixedly mounted on the switch shell 203, the cooling pipe 204 is distributed on both sides of the battery 101, and the outlet end of the cooling pipe 204 is connected to another switch shell 203.

[0038] like Figure 8-Figure 10As shown, an opening mechanism is provided on the shell 4, and the opening mechanism includes a single-leaf rotating block 209 rotatably mounted on the shell 4, a torsion spring 210 is provided between the single-leaf rotating block 209 and the shell 4, an inner rotating block 206 is rotatably mounted in the switch shell 203, a through hole is provided on the inner rotating block 206, the inner rotating blocks 206 of the two switch shells 203 are fixedly connected by a long axis 207, a rotating wheel 205 is fixedly mounted on the inner rotating block 206, and an opening transmission belt 208 is wound around the rotating wheel 205 and the single-leaf rotating block 209.

[0039] As the heated and expanded gas in the air push box 105 continues to expand, it drives the inner push plate 120 and the lifting frame 117 to continue to rise. At this time, the fan 107 alone cannot effectively dissipate heat. The rise of the lifting frame 117 will drive the single-leaf rotating block 209 to rotate, and the torsion spring 210 will be twisted, thereby turning on the transmission belt 208 to drive the rotating wheel 205, the inner rotating block 206 and the long shaft 207 to rotate, thereby realizing the rotation of the two cooling pipes 204, so that the through hole of the inner rotating block 206 is connected to the cooling pipe 204, and the built-in water pump in the water cooling box 201 passes the cooling water into the cooling pipe 204, and the battery 101 is cooled through the cooling pipe 204. When there is insufficient water in the water cooling box 201, water is replenished through the water inlet pipe 202.

[0040] like Fig. 9 , Fig.10 As shown, the forced cutting device includes a fixed inner column 306 fixedly mounted on the fixed block 301, a movable block 303 is slidably mounted on the fixed inner column 306, an upper push plate 307 is fixedly mounted on the movable block 303, a magnet 304 is fixedly mounted on the fixed block 301, a magnetic sheet 308 is fixedly mounted on the lifting frame 117, a tension spring 302 is arranged between the movable block 303 and the fixed block 301, an external terminal 305 is inserted into the movable block 303, the movable block 303 and the external terminal 305 form an interference fit, and the external terminal 305 is tightly attached to and connected with the terminal 102.

[0041] When the water cooling device is started, if the inner push plate 120 and the lifting column 118 continue to rise, the lifting frame 117 continues to rise, which will drive the top column 116 to rise. At this time, water cooling and blowing can no longer achieve the cooling effect, and the external terminal 305 needs to be disconnected from the terminal 102. When the top column 116 rises, the magnetic sheet 308 reaches a certain range of the magnet 304, and the magnetic sheet 308 will be attracted by the magnet 304. The magnetic sheet 308 drives the lifting frame 117 and the top column 116 to rise, and the top column 116 will be on the top. The push plate 307 and the movable block 303 are lifted up, and the movable block 303 slides upward along the fixed inner column 306. The tension spring 302 is stretched, and the movable block 303 rises to drive the external terminal 305 to rise. The external terminal 305 is separated from the terminal 102. At this time, the battery 101 stops supplying power to the outside, and the alarm 133 starts to alarm. The magnet 304 keeps adsorbing the magnetic sheet 308. After manual inspection, the magnetic sheet 308 and the magnet 304 are manually separated to reset the lifting frame 117.

[0042] The working principle of a self-heating storage battery with a self-checking function disclosed in the present invention is as follows: the battery 101 generates heat when working, and the gas in the air push box 105 expands when heated, which drives the inner push plate 120 and the lifting column 118 to rise. When the lifting column 118 rises, it drives the lifting frame 117 to rise, thereby driving the top column 116 and the plastic block 123 to rise. When the lifting frame 117 rises a certain distance, the outer contact piece 124 and the inner contact piece 127 enter between the electrode plate 131 and the docking electrode plate 132. The outer spring 126 and the inner spring 129 make the outer contact piece 124 and the electrode plate 131 in close contact, and the inner contact piece 127 and the docking electrode plate 132 in close contact. The current passes through the terminal 102 and the power is taken. Wire 121, electrode plate 131, outer contact piece 124, inner contact piece 127, docking electrode plate 132 and motor wire 122 are connected to motor 112, motor 112 starts to rotate, driving motor wheel 113 to rotate, thereby driving fan wheel 108 to rotate through fan drive belt 109, thereby driving fan blades of fan 107 to rotate, cooling battery 101, and driving horizontal drive wheel 115 and long rotating shaft 104 to rotate through horizontal drive belt 114, thereby driving fan 107 on the other side of battery 101 to rotate synchronously, and as lifting frame 117 continues to rise, outer contact piece 124 and inner contact piece 127 are always located between electrode plate 131 and docking electrode plate 132, and fan 107 keeps working. When the battery 101 is not working and is at room temperature, if the amount of heat-expanded gas in the air push box 105 is insufficient, the inner push plate 120 and the lifting column 118 will descend, thereby driving the lifting frame 117 to descend. When the lifting frame 117 contacts the sensor sheet 110, the alarm 133 alarms to prompt that the heat-expanded gas in the air push box 105 is insufficient. At this time, it is connected to the one-way valve 106 through the external air pipe, and the one-way valve 106 is opened to replenish the heat-expanded gas in the air push box 105. As the heated and expanded gas in the air push box 105 continues to expand, it drives the inner push plate 120 and the lifting frame 117 to continue to rise. At this time, the fan 107 alone cannot effectively dissipate heat. The rise of the lifting frame 117 will drive the single-leaf rotating block 209 to rotate, and the torsion spring 210 will be twisted, thereby turning on the transmission belt 208 to drive the rotating wheel 205, the inner rotating block 206 and the long shaft 207 to rotate, thereby realizing the rotation of the two cooling pipes 204, so that the through hole of the inner rotating block 206 is connected to the cooling pipe 204, and the built-in water pump in the water cooling box 201 passes the cooling water into the cooling pipe 204, and the battery 101 is cooled through the cooling pipe 204. When there is insufficient water in the water cooling box 201, water is replenished through the water inlet pipe 202.When the water cooling device is started, if the inner push plate 120 and the lifting column 118 continue to rise, the lifting frame 117 continues to rise, which will drive the top column 116 to rise. At this time, water cooling and blowing can no longer achieve the cooling effect, and the external terminal 305 needs to be disconnected from the terminal 102. When the top column 116 rises, the magnetic sheet 308 reaches a certain range of the magnet 304, and the magnetic sheet 308 will be attracted by the magnet 304. The magnetic sheet 308 drives the lifting frame 117 and the top column 116 to rise, and the top column 116 will be on the top. The push plate 307 and the movable block 303 are lifted up, and the movable block 303 slides upward along the fixed inner column 306. The tension spring 302 is stretched, and the movable block 303 rises to drive the external terminal 305 to rise. The external terminal 305 is separated from the terminal 102. At this time, the battery 101 stops supplying power to the outside, and the alarm 133 starts to alarm. The magnet 304 keeps adsorbing the magnetic sheet 308. After manual inspection, the magnetic sheet 308 and the magnet 304 are manually separated to reset the lifting frame 117.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
