The invention comprises a main device of the battery current fuse protector, wherein one side of the main device of the battery current fuse protector is connected with a fuse protection reminder device, and the other side is connected with a fuse tilting rod. The fuse in the fuse tilting rod is melted by the heat generated by the current exceeding a threshold value, so that the upper tilting rod loses balance, thereby realizing the descent of a round rod, and the descent of an extrusion block is used to extrude a lower pressing block filled with condensate to complete the cooling, prevent the device from being damaged due to excessive temperature, and dissipate heat for the entire circuit and the battery.

Description

Technical Field

[0001] The invention relates to the technical field of fuse protectors, in particular to a battery current fuse protector. Background Art

[0002] Current fuses are usually used to protect various components in the circuit. The core component, the fuse, is usually made of aluminum alloy, lead-tin, aluminum alloy or zinc. The fuse is also called a fuse, a fuse piece, etc. The rated current is usually used as its specification. Different fuses have different rated currents that can be carried. When the current in the circuit is less than the specified value of the fuse, the fuse will not break. When the current in the circuit is greater than the specified value of the fuse, that is, when the electrical equipment in the circuit is overloaded or short-circuited, the fuse itself will generate heat, melt itself through the generated heat, and break. When the fuse breaks, the circuit is disconnected to protect the circuit from damage to components or equipment caused by the thermal effect of the current, so as to achieve the purpose of protecting the circuit. However, in actual use, the heat dissipated by the fuse is too large, and sometimes the heat dissipated during its own break may affect and damage the surrounding components. If there are combustibles around the fuse, it may cause the combustion of combustibles. There is a certain risk, and the traditional fuse can only be found when the user opens the equipment. A battery current fuse protector provided by the present invention mainly protects the battery. As one of the important components in the circuit, the battery provides power for other components. The present invention adds a fuse protection reminder device and a fuse lift rod on the basis of an ordinary current fuse protector. The fuse protection reminder device reminds the user of the fuse being blown, and the fuse is cooled by the condensate in the fuse protection reminder device to avoid the harm caused by the high temperature generated when the fuse is blown, thereby improving the safety during its use.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. A battery current fuse protector, by setting a downward pressing block, using the deadweight of the downward pressing block to exert a downward force on the winding rod, so that the entire fuse tilting rod is in a balanced state tilted in the direction of the downward pressing block, by setting a winding rod on the second panel, the hole of the upward tilting rod is connected with the winding rod, forming a structure similar to a seesaw, when the upward tilting rod fuse is melted by the heat generated by the current, the balance state is broken, and the upward tilting rod moves by the movement of the hole of the upward tilting rod on the winding rod to make an arc-shaped trajectory, and by setting the upward tilting rod The rod is fixedly connected to the upward connecting block, and the upward connecting block is fixedly connected to the caliper plate to drive the caliper plate to move downward, thereby realizing the descending behavior of the round rod. The descending behavior of the round rod drives the extrusion block to descend and extrude. By storing condensate in the downward pressing block and utilizing the extrusion effect of the extrusion block, the condensate is driven into the hollow protective shell to complete the cooling of the device and prevent the device from being damaged due to overtemperature. At the same time, the hollow protective shell filled with condensate can cool the entire circuit and dissipate heat for the entire circuit and the battery.

[0016] 2. A battery current fuse protector, which sets the initial liquid water level of the condensate in the condensate extrusion tube at the connecting junction between the condensate extrusion tube and the hollow protective shell, thereby ensuring that when the extrusion block extrudes the lower pressing block, the condensate in the condensate extrusion tube first enters the hollow protective shell, and the condensate stored in the lower pressing block first enters the condensate extrusion tube and then is pumped into the hollow protective shell under the action of the extrusion block, thereby ensuring that the condensate can completely fill the entire hollow protective shell cavity, ensuring that the condensate in the hollow protective shell cavity is evenly distributed, and avoiding uneven cooling.

[0017] 3. A battery current fuse protector, which ensures that the current is not transmitted to the upward connecting block after passing through the upward rod by setting an upward connecting block. The fuse protection reminder device is made of conductive material except for the extrusion rod, and a small motor is connected to the motor connection port. The small motor is connected to a power supply, and the current reaches the lifting mechanism on the fuse protection reminder device through the small motor. By setting the lifting mechanism, the lifting action of the upper pressure plate is used to lift the extrusion block fixedly connected to the upper pressure plate, thereby driving the extrusion block to rise. Through the short rise of the extrusion block, the extrusion block is separated from the lower pressure block again, the current is interrupted, and the small motor stops working. Under the action of gravity, the extrusion block drops again, and the extrusion block makes a second contact with the bottom of the lower pressure block, and the current transmission of the small motor is restored. The above actions are repeated, and the collision generated by the extrusion block and the lower pressure block makes a sound to remind the user that the battery current fuse protector has been fused, so that the battery can be repaired and protected in time to extend its service life.

[0018] 4. A battery current fuse protector ensures that when the upper pressure plate descends, the upper pressure plate does not fully contact the upper surface of the lower pressure block by setting a spring. The power current connected to the small motor can only be transmitted through the lower surface of the extrusion block in contact with the lower pressure block, ensuring that the motor is not triggered when the extrusion block has not completely squeezed the condensate in the lower pressure block, thereby avoiding unnecessary work of the small motor and reducing its own consumption.

[0019] 5. A battery current fuse protector, which realizes the lifting action of the upper pressure plate by setting the lifting plate as an irregular arc-shaped panel and utilizing its shape with one side high and the other side low. The stability of the lifting plate and the fixed movement trajectory are ensured by setting a fixed track, ensuring that it is not easy to shake or fall when the lifting cylinder contacts it, ensuring that the upper pressure plate can be stably lifted and lowered.

[0020] 6. A battery current fuse protector, which is threadedly connected to a hollow protective shell by setting a first panel and a second panel. When the fuse 1011) and the upward rod fuse are blown, the user can replace them by opening the screws on the first panel, thereby improving the reuse rate of the device and avoiding waste of resources.

[0021] 7. A battery current fuse protector, by arranging a winding rod connected to the second panel, and sleeved on the upward rod through the winding rod, to ensure that the upward rod can perform an incomplete circular motion around the winding rod after the fuse of the upward rod is blown, thereby realizing the descent of the fuse protection reminder device.

[0044] The first panel 102 is provided with a first panel hole 1021 , the second panel 104 is provided with a long arc groove 1041 , and a revolving rod 1042 is fixedly connected inside the groove of the second panel 104 .

[0045] Embodiment: Step 1: Connect the battery current fuse protector to the powered end of the battery, turn on the battery, and when the current and voltage of the entire circuit run smoothly within the threshold, the battery current fuse protector does not blow, and the circuit runs normally. The current in the battery current fuse protector is conducted through the small conductive head 1011 to the fuse 1011 and the large conductive head 1013, and the current is safely transmitted to the circuit. In the same time period, the current passes through the winding rod 3011, and the winding wire 3012 is wound on one end of the winding rod 3011. One end of the winding wire 3012 is connected to the downward pressing block 3013. The downward pressing block 3013 has a certain deadweight. The downward pressing block 3013 pulls the winding wire 3012 by its deadweight, so that the winding rod 3011 tilts downward. The other end of the winding rod 3011 is fixedly connected to the downward pressing tilting rod 302, and the current is conducted to the downward pressing tilting rod 302. The other end of the downward pressing tilting rod 302 is connected to the upward tilting rod fuse 303. The current is conducted to the upward tilting rod fuse 303 through the downward pressing tilting rod 302. The tail of the upward rod fuse 303 is fixedly connected to the upward rod 304, and the current is transmitted to the upward rod 304 through the upward rod fuse 303. The winding rod 1042 is sleeved in the small hole 3041 opened on the upward rod 304. The other end of the upward rod 304 is fixedly connected to the upward connection block 305. The upward connection block 305 is made of insulating material and is not conductive. The upward connection block 305 is fixedly connected to 2012. The caliper groove 2012a opened on 2012 is stuck on the winding clamp wheel 2011b. The entire fuse lifting rod 3 is in a force balance state tilted downward in the direction of the downward pressing mechanism 301.

[0046] Step 2: When the working current and voltage in the circuit in the previous step exceed the threshold value, the current in the battery current fuse protector is conducted through the small conductive head 1011 to the blown fuse 1011. The blown fuse 1011 generates heat under the action of the overload current and is blown by the heat generated by itself. After the blown fuse 1011 is blown, the battery and the components in the entire circuit are protected. In the same time period, the current passes through the downward pressing mechanism 301 to reach the downward pressing tilting rod 302. When the current on the downward pressing tilting rod 302 is transmitted to the upward tilting rod melting fuse 303, the current threshold of the upward tilting rod melting fuse 303 is the same as that of the melting fuse 1011. The upward tilting rod melting fuse 303 generates heat to melt. Since the upward tilting rod melting fuse 303 is broken, the force balance state of the entire melting tilting rod 3 is broken. The upward tilting rod hole 3041 opened on the upward tilting rod 304 fixedly connected to the tail of the upward tilting rod melting fuse 303 is sleeved with the winding rod 1042. One end of the upward tilting rod 304 loses the force of the upward tilting rod melting fuse 303, and the other end of the upward tilting rod 304 is affected by the caliper connected to the upward connecting block 305. The gravity of plate 2012 starts to move downward around the orbiting rod 1042 as the axis, and the caliper plate 2012 fixedly connected to the upturned connecting block 305 also starts to move downward. The caliper groove 2012a on the caliper plate 2012 is clamped on the orbiting clamp wheel 2011b, one end of the extrusion rod 2017 is sleeved on the hole 2013 of the upper pressure plate, and the other end of the extrusion rod 2017 is sleeved on the hole 2018 of the lower pressure plate. The movement of the caliper plate 2012 drives the round rod 2011 to move downward along the extrusion rod 2017. When the upper support cap 2017a on the extrusion rod 2017 hits the hole 2013 of the upper pressure plate and the lower pressure block 2016 hits the spring 2017c, the spring 2017c performs buffering.

[0047] Step 3: In the previous step, the round rod 2011 moves downward, and the extrusion block 2015 fixedly connected to the bottom of the round rod 2011 also moves downward, and the extrusion block 2015 enters the square groove opened inside the lower pressing block 2016 through the groove opening 2016a of the lower pressing block. The lower pressing block 2016 is filled with condensate, and the condensate extrusion tube 202 is also filled with condensate. When the extrusion block 2015 is not performing an extrusion movement, the liquid water level of the condensate is at the connection point between the condensate extrusion tube 202 and the bottom of the hollow protective shell 103. When the extrusion block 2015 is pressed downward, the condensate in the lower pressing block 2016 is squeezed downward, and the squeezed condensate enters the condensate extrusion tube 202, generating thrust on the condensate extrusion tube 202, and the condensate in the condensate extrusion tube 202 begins to be pumped out of the hollow protective shell 103. The hollow protective shell 103 is a hollow shell. The condensate pumped out from the condensate extrusion tube 202 fills the entire cavity of the hollow protective shell 103, and the temperature in the hollow protective shell 103 is cooled and the heat is dissipated.

[0048] Step 4: When the extrusion block 2015 is completely squeezed downward and the condensate in the lower pressing block 2016 is completely pumped out, the extrusion block 2015 completely contacts the bottom of the lower pressing block 2016. The entire fuse protection reminder device 2 is made of conductive material. A small motor is connected to the motor connection port 2034. When the extrusion block 2015 does not contact the lower pressing block 2016, the current passing through the small motor is disconnected in the lower pressing block 2016, and the small motor does not work. When the extrusion block 2015 completely contacts the lower pressing block 2016, the small motor and the push rod 2033 and the lifting plate 2031 on the push rod 2033 form a complete circuit. The current flows through the extrusion block 2015 and the lower pressing block 2016, and the small motor starts to work, driving the motor connection port 2034 to move forward, as shown in the attached figure. Fig.12 As shown, the motor connection port 2034 is fixedly connected to the push rod 2033, driving the push rod 2033 to move forward, and the lifting plate 2031 fixedly connected to the push rod 2033 moves forward along the fixed track 2032. The upper pressure plate 2014 in the previous step has moved to the point where the lifting cylinder 2014a contacts the lifting plate 2031, and the lifting cylinder 2014a is close to the lifting plate 2031. The lifting cylinder 2014a is gradually lifted during the forward movement of the lifting plate 2031.

[0049] Step 5: In the previous step, the entire upper pressing plate 2014 is lifted by gradually lifting the lifting cylinder 2014a. The upper pressing plate 2014 sleeved on the extrusion rod 2017 moves upward along with the lifting of the extrusion rod 2017. The extrusion block 2015 fixedly connected to the upper pressing plate 2014 moves upward, and the round rod 2011 fixedly connected to the extrusion block 2015 moves upward. Since the other end of the extrusion rod 2017 is sleeved on the hole 218 of the lower pressing plate, the hole 218 of the lower pressing plate moves upward along with the upward movement of the extrusion rod 2017. It rises during the movement, and the extrusion block 2015 separates from the bottom of the lower pressing block 2016. The condensate flows back into the condensate extrusion tube 202 and the lower pressing block 2016. The current is terminated, the small motor stops working, and the upper pressing plate 2014 drops again until the extrusion block 2015 fixedly connected to the upper pressing plate 2014 contacts the bottom of the groove of the lower pressing block 2016 again, and the current is restored. The above-mentioned movements are repeated in sequence. When the extrusion block 2015 collides with the lower pressing block 2016, a sound is emitted to remind the user that the circuit is faulty.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
